Exclusive natural DHA/EPA enrichment processes THE POWER OF MOTHER NATURE TO ENRICH, PRESERVE AND FILTER

NEO-3™: Enzymatic cleavage

Enrichment through the power of natural digestive enzymes We gently concentrate the levels of EPA and DHA by using natural lipase enzymes (and no alcohol or chemicals) which selectively remove shorter chain fatty acids from the fish oil triglyceride, leaving the EPA and DHA untouched. This NEO-3™ process mimics the first stages of our normal digestive process and produces a mixture of natural tri- and di-glycerides with enriched levels of EPA and DHA. SHORTER FATTY ACIDS

Enrichment through the strength of nature’s cold grip When subjected to low temperature, triglycerides that have a high proportion of saturated fatty acids start to solidify due to the higher ‘freezing point’ of saturated fatty acids compared to unsaturated fatty acids such as EPA and DHA. In the CRYO-3 process, the fish oil is gradually taken to very low temperatures, enabling accurate fractional crystallization or ‘precipitation’ of the triglycerides carrying high levels of saturated fatty acids.

Once the solid fractions have been separated, the remaining liquid fraction has a higher ratio of EPA and DHA.

Happy New Year!

A

s spring approaches a fresh start awaits all of us... IHP has undergone some tremendous changes as-of late, changes we are very pleased with: we have created the Journal of IHP, and we have welcomed a talented, energetic, and experienced new Associate Editor in Chris Habib. Excited to see IHP continue to grow into 2013 and beyond!

The Natural Health Products Directorate of Health Canada has pledged enforcement of their recently- created requirements for natural health products. This should serve to bring clarity on where things stand between many brands in the marketplace.

Reflecting on the year that was has me rethinking the role of technology in my life... As much as I embrace technology I have come to notice that in many ways it has made people somewhat antisocial.

People are walking around typing away on their mobile devices instead of taking in their surroundings... My New Year’s resolution this year is less time with devices, more time spent picking up a phone and calling someone.

Overall it has been an excellent start to what is shaping up to be an incredible year... Enjoy the ride!

The 4 Herb Formula

Product Monograph for IHP, Feb 2013

By Terry Vanderheyden, ND

At 30% of all deaths, cancer now exceeds cardiovascular disease as the number one killer in Canada. From 2000 to 2009, deaths caused by cancer increased in Canada by 13.5% (StatsCan 2009). In the US in 2009, however, cardiovascular disease still exceeded cancer as the leading killer.

Rene Caisse Canadian operating room nurse Rene Caisse learned of this herbal formula in 1922 from a patient who had recovered from cancer with a mix of herbs given to her by an Ojibwe medicine man. A few months later, Caisse’s aunt was diagnosed with metastatic stomach cancer. Caisse decided to employ the newfound treatment and administered the tea. Her aunt recovered and lived another 21 years, cancer-free. Caisse opened a clinic in Bracebridge, Ontario in 1933 and began using the formula with cancer patients.

Royal Cancer Commission and Dr. Benjamin Guyatt A Royal Cancer Commission was set up in 1938 to investigate Caisse’s work. Dr. Benjamin Guyatt, a University of Toronto professor of anatomy, spent time in her clinic as an independent observer. He testified at the Commission, noting that, â€œâ€Ś I saw patients come in, in very bad shape, and the next time I went along I found improvement in a number of those cases.â€? As a result, he prompted the Canadian Medical Association to investigate her work. (Glum 1988) Mary McPherson There has been some controversy over the authentic formula used by Caisse. Mary McPherson is the only person, besides Caisse herself, who prepared the tea for use in her clinic. On December 23, 1994, McPherson divulged the recipe in her own handwriting, in a sworn affidavit (McPherson 1994). It is this same formula, originally published in Gary Glum’s 1988 book, that St. Francis Herb Farm makes, both in the original tea format as well as in a convenient tincture formula.

Alterative St. Francis Herb Farm’s Four Herb Tea and The ‘4’ Herb Formula (tincture) are alterative combinations designed specifically to support detoxification and the treatment of conditions of a degenerative nature, as well as the general maintenance of good health. Alteratives, it should be noted, are that class of herbal medicines that amend the metabolic processes, enabling the body to deal properly with nutrition and eliminative functions, gradually ridding it of waste tissue.

Terry Vanderheyden, ND (Research Consultant) Terry Vanderheyden, ND, has practiced in Ontario since graduating from the CCNM in 1994, specializing in homeopathic, nutritional, and botanical therapies.

He also works as a consultant for St. Francis Herb Farm, Inc. Terry lives in Barry’s Bay with his wife Laurie and their six children.

The herbs In terms of specific indications relating to the individual ingredients, medieval German philosopher, herbalist, and religious, St. Hildegard of Bingen, used burdock (Arctium lappa) to treat cancerous tumours (Kemper 1999). Taking the history of its use as a folk remedy for abnormal growths as their point of departure, scientists Dombradi and Foldeak (1966) screened burdock for antitumor activity and noted significant properties.

Meanwhile, J. Milton Welch, M.D. classes sheep sorrel as an alterative, calling it “a great cancer remedyâ€? (Welch 1882). Fellow Eclectic physician John M. Scudder, M.D. adds regarding sheep sorrel that, â€œâ€Ś Its use in the treatment of cancer has been quite extensive, and if we can believe the reports given, it has proven fully as successful as any other remedy.â€?

Sereniten Plus

An effective solution consisting of Lactium®, L-Theanine and Vitamin D to reduce the symptoms of mental and physical stress.

A novel formula with anxiolytic activity • Bioactive decapeptide Lactium® with specific binding to GABA (A-1) receptors • Appropriate receptor binding without the side effects of drowsiness, memory loss, tolerance or addiction • Re-establishes the HPA feedback loop by increasing the sensitivity of the hypothalamus to cortisol • Decreases cortisol and CRH during chronic stress

Unregulated elevated levels of cortisol impair stage four delta wave sleep, destabilize mast cells, inhibit digestive enzyme production and increases endothelin and LDL levels. All of these effects contribute to increased cardiovascular disease, allergies, IBS and IBD. Balancing the hypothalamic-pituitary axis by re-establishing appropriate sensitivity within the feedback loop assists in mitigating these effects and normalizing cortisol levels.

research news Fruit, vegetable, and antioxidant intakes are lower in older adults with depression

Caffeinated and caffeinefree beverages and risk of type 2 diabetes This study prospectively examined the association of caffeinated compared with caffeine-free beverages, including coffee, tea, sugar-sweetened beverages (SSBs), and carbonated artificially sweetened beverages (ASBs), with Type 2 Diabetes (T2D) risk. 74,749 women from the Nurses’ Health Study (NHS, 1984-2008) and 39,059 men from the Health Professionals FollowUp Study (HPFS, 1986-2008) were followed. After major lifestyle and dietary risk factors were controlled for, caffeinated and caffeine-free SSB intake was significantly associated with

a higher risk of T2D in the NHS (RR per serving: 13% for caffeinated SSB, 11% for caffeine-free SSB; P < 0.05) and in the HPFS (RR per serving: 16% for caffeinated SSB, 23% for caffeinefree SSB; P < 0.01). Only caffeinefree ASB intake in NHS participants was associated with a higher risk of T2D. Conversely, the consumption of caffeinated and decaffeinated coffee was associated with a lower risk of T2D. Only caffeinated tea was associated with a lower T2D risk among NHS participants (RR per serving: 5%; P < 0.0001). The authors conclude that SSB intake was associated with a higher risk of T2D and coffee intake was associated with a lower risk of T2D.Am J ClinNutr.

CBT causes an improvement in quality of life in patients with chronic musculoskeletal pain This randomized controlled study examined the effectiveness of cognitive behavioral therapy (CBT) in a group of patients with chronic pain. Chronic pain causes functional incapacity and compromises an individual’s affective, social, and economic life. CBT is a psychotherapeutic approach that targets maladaptive behaviours and cognitive processes by utilizing goal-oriented procedures. It is generally used for a variety of health conditions, including anxiety, mood disorders, substance abuse, disordered eating, and psychotic disorders. This randomized clinical trial employed two parallel groups comprising 93 patients with chronic pain. Forty-eight patients were submitted to CBT and 45 continued the standard treatment. The visual analogue, hospital anxiety and depression, and quality of life SF-36 scales were applied. Patients were evaluated before and after ten weeks of treatment.When the Control Group and CBT were compared, the CBT group had a reduction of depressive symptoms (p=0.031) and improvement in the domains ‘physical limitations’ (p=0.012), ‘general state of health’ (p=0.045), and ‘limitations by emotional aspects’ (p=0.025).Therefore, CBT was effective and showed an improvement in more domains of quality of life when compared to the Control Group, after ten weeks of treatment. ArqNeuropsiquiatr. 2012 Nov;70(11):864-8. PMID: 23175199

This study examined the crosssectional associations between clinically diagnosed depression and intakes of antioxidants, fruits, and vegetables in older adults. Antioxidant, fruit, and vegetable intakes were assessed in 278 elderly participants (144 with depression, 134 without depression) using a food frequency questionnaire

that was administered between the years 1999 and 2007. All participants were aged 60 years or older. Vitamin C, lutein, and beta cryptoxanthin intakes were significantly lower among individuals with depression than in comparison participants (P<0.05). In addition, fruit and vegetable consumption, a primary determinant of antioxidant intake, was lower in individuals with clinical depression. In multivariable models controlling for age, sex, education, vascular comorbidity score, body mass index, total dietary fat, and alcohol; vitamin C, beta cryptoxanthin, fruits, and vegetables remained significant.

Antioxidants from dietary supplements were not associated with depression.

Antioxidant, fruit, and vegetable intakes were lower in individuals with latelife depression than in comparison participants. The authors conclude that these associations may partially explain the elevated risk of cardiovascular disease among older individuals with depression and point to the importance of antioxidant food sources rather than dietary supplements.

research news Patient-reported experiences with first-time naturopathic care for type 2 diabetes This study provides the first report of the perceptions of persons with type 2 diabetes of their first experiences with naturopathic care for their diabetes. This study was conducted in a naturopathic clinic at Bastyr University in Washington.

Following their participation in a one-year prospective cohort study of adjunctive naturopathic care for diabetes, twenty-two patients were interviewed about their experiences working with a naturopathic physician (ND). Using a content analysis approach, nine dominant themes were identified. Three themes characterized the nature of the ND-patient interaction: 1) patient-centered, 2) holistic health rather than diabetes focused, and 3) collaborative. Five themes characterized the content of the clinical encounter: 1) individualized and detailed health promotion, 2) counseling that promoted self-efficacy, 3) pragmatic and practical self-care recommendations, 4) novel treatment options that fostered hopefulness, and 5) patient education that addressed both diabetes self-care and general health. A ninth theme was cross-cutting: the contrast between ND care and conventional medical care. The results of this study indicate that the routine clinical approach used by NDs is consistent with behaviour change theory and clinical strategies found most effective in promoting self-efficacy and improving clinical outcomes. PLoS One. 2012;7(11):e48549. PMID: 23144900

Exercise for cancer-related fatigue during and following treatment: a meta-analysis This meta-analysis examined the improvements in fatigue due to exercise training. Articles were retrieved using Google Scholar, MEDLINE, PyscINFO, PubMed, and Web of Science databases.

Seventy studies involving 4881 cancer patients during or following treatment were utilized. Articles were included when they utilized randomized allocation to exercise or non-exercise and had outcome measures of cancer-related fatigue at baseline and post-intervention. Effect sizes were computed and the quality of the studies was evaluated. A random effects model was used to estimate sampling error and population variance. The evidence

demonstrated that exercise significantly reduced cancer-related fatigue by a mean effect change of 0.32 (0.21, 0.43) and 0.38 (0.21, 0.54) during and following cancer treatment, respectively. During treatment, patients with lower baseline fatigue scores and higher exercise adherence had the largest improvements.

After treatment, those who were in trials with a longer duration between treatment completion and exercise initiation had the largest improvements. Those in trials with shorter exercise program lengths and wait-list comparisons also had the largest improvements. Therefore, the authors conclude that exercise has a palliative effect and reduces cancer-related fatigue for cancer patients both during and following cancer treatment.

Meta-analysis of probiotics during helicobacter pylori eradication therapy

This meta-analysis examined whether Lactobacillus-containing and Bifidobacterium-containing probiotic compound preparations could improve Helicobacter pylori (H. pylori) eradication rates and limit side effects. This study included all parallel controlled trials comparing Lactobacillus-containing and Bifidobacterium-containing probiotic compound preparations supplementation or not during H. pylori eradication therapy.

Statistical analysis was performed with the Stata version 11.0 software. Subgroup analysis and sensitivity analysis were also performed. The results included ten clinical trials in the meta-analysis. Eradication odds ratio (OR) was available for 1469 patients (708 in probiotics supplementation group and 761 in the control group).

The pooled OR by intention-to-treat analysis and by per-protocol analysis in the probiotics supplementation versus without probiotics was 2.066 [95% confidence interval (CI), 1.398-3.055] and 2.321 (95% CI, 1.715-3.142), respectively.

The pooled OR of incidence of total side effects was significantly decreased in the probiotics supplementation group (OR=0.305; 95% CI, 0.117-0.793) by the random model without significant publication bias. Therefore, this study showed that Lactobacillus-containing and Bifidobacterium-containing probiotic compound preparations during initial H. pylori eradication therapy in adults may have beneficial effects on eradication rate and incidence of total side effects.

Product Monograph

PROGRESSIVE NUTRITIONAL THERAPIES OMEGESSENTIAL™ Progressive OmegEssential™ is a high potency blend of cold water, wild caught, purified fish oil along with a family of strategic support nutrients.

Fish Oils for the Maintenance of Good Health As a source of omega-3 fatty acids, namely EPA and DHA, fish oils aid in the maintenance of good health, help support cognitive health/brain function and cardiovascular health (NHPD Monograph: Fish Oil).

Fontani, et al (2005) conducted a study to evaluate the effect of omega-3 supplementation on cognitive performance in 33 normal healthy men and women (aged 22 – 51 years) during a 35-day period. Tests involving different types of attention were used, along with the Profile of Mood States (POMS). Results showed a mood profile with increased vigour and reduced anger, anxiety and depression states after omega-3.

Furthermore, findings indicated that omega-3 supplementation is associated with an improvement of attentional and physiological functions, particularly those involved in complex cortical processing.

Higher consumption of fish and omega-3 fatty acids has been associated with a lower risk of coronary heart disease (CHD). Hu, et al (2002) examined the association between fish and omega-3 fatty acid consumption and risk of CHD in women. Dietary consumption and follow-up data from 84,688 female nurses (aged 34 to 59 years) free from cardiovascular disease and cancer were compared from validated questionnaires. The outcomes indicated that women who consumed more fish and fish oil (omega-3 fatty acids) significantly reduced their risk of heart disease (particularly CHD deaths) by 30%, compared to women who rarely ate fish.

Similarly, a prospective, nested case-control analysis was performed among apparently healthy men, who had no evidence of prior heart disease by Albert, et al (2002) to address the hypothesis that long-chain omega-3 fatty acids found in fish are associated with a reduced risk of sudden death from cardiac causes. The fatty-acid composition of whole blood in 184 men was compared with the previously collected blood of 94 men, in whom sudden death occurred as the first manifestation of cardiovascular disease. The study reported that men who consumed long-chain omega-3 fatty acids had a significantly reduced risk of sudden death.

Dosage Indication: Fish Oil Supplement. Helps support cardiovascular health, brain function and healthy mood balance.

Vitamin B-12 and folate deficiencies predict cognitive decline This prospective epidemiological study investigated the cognitive significance of low plasma vitamin B-12 concentrations and the role that folate status plays. The authors evaluated vitamin B-12 and folate during an 8-year period. The Framingham Heart Study was used to provide data for analysis. Five hundred forty-nine individuals with a mean age of 74.8 were studied. The measurements included a mini-mental status examination (MMSE), plasma folate, vitamin B-12, methylmalonic acid, homocystieine, demographic factors, and body mass index. The results showed that MMSE scores declined by 0.24 points

per year over the follow-up period. The decline was significantly faster in cohort members who were in the bottom two plasma vitamin B-12 quintile categories. No cognitive advantage was associated with plasma vitamin B-12 in higher categories.

In those with lower vitamin B-12 levels, a plasma folate concentration greater than 20.2 nmol/L was associated with a 1-point per year decline, as was the use of supplemental folate. The authors conclude that plasma vitamin B-12 levels from 187 to 256.8 pmol/L predict cognitive decline.

In addition, having vitamin B-12 levels in this range or below with high plasma folate or using supplemental folate predicts rapid cognitive decline. J Am Geriatr Soc. 2012;60(8):1457-64.PMID: 22788704

Recovery of probiotic in tonsil tissue after oral administration This randomized, double-blind, placebo-controlled study was conducted to determine whether consumption of probiotic Lactobacillus rhamnosus GG (GG) would lead to the recovery of GG in tonsil tissue. After 3 weeksâ&#x20AC;&#x2122; daily consumption of GG as a single strain (twenty patients), GG as a part of a multispecies combination (17 patients) or placebo (20 patients), tonsil tissue samples were collected from fifty-seven young adults during tonsillectomy due to chronic or recurrent tonsillitis. Strain-specific real-time PCR was used to detect GG in the tonsil tissue. GG was recovered in the tonsil sample of 40% of the subjects in the GG group, 41% in the multispecies group and 30% in the placebo group. In all subjects with positive recovery of GG in the tonsil tissue, GG was also recovered in the fecal sample taken at the start of the intervention and at the time of the tissue sample collection, which indicates more persistent adherence of the probiotic. Therefore, the results of this study demonstrate that GG can be recovered from tonsil tissue after oral administration as a single-strain probiotic or as a part of a multispecies probiotic combination.

This prospective cohort and metaanalysis investigated the association between chocolate consumption and the risk of stroke in men and conducted a meta-analysis to compile the available evidence from prospective studies. 37,103 men were followed prospectively in the Cohort of Swedish Men. A food-frequency questionnaire was used at baseline to assess for chocolate consumption. Cases of first

stroke were obtained from the Swedish Hospital Discharge Registry. For the meta-analysis, pertinent studies were identified using PubMed and EMBASE databases. Study-specific results were combined using a randomeffects model. The results of the study showed that during 10.2 years of followup, there were 1,995 incident cases of stroke, including 1,511 cerebral infarctions, 321 hemorrhagic strokes, and 163 unspecified strokes. It was found that high chocolate consumption was associated with a lower risk of stroke. The multivariable relative risk of stroke comparing the highest quartile of consumption (62.9g/week) with the lowest (0g/week) was 0.83 (95% CI 0.70-0.99). This did not differ by stroke subtypes. In the meta-analysis of 5 studies, the overall relative risk of stroke for the highest versus lowest category of consumption was 0.81 (95% CI 0.730.90), suggesting moderate chocolate consumption may lower stroke risk.

research news Effect of essential oil aromatherapy on heart rate and blood pressure This study examined the use of aromatherapy to measure its impact on heart rate and blood pressure. 100 healthy spa workers in Taiwan were recruited from various spa centers.

Three repeated measurements of resting heart rate, systolic blood pressure, and diastolic blood pressure were taken of each spa worker in a study room.

Participants were exposed to essential oil vapour that was generated from an ultrasonic atomizer for two consecutive hours. The total volatile organic compound level in the study room was measured.

The results showed that for times from 15 minutes to 60 minutes after the start of exposure, the volatile organic compound level was significantly associated with reduced 15 minute mean blood pressure and heart rate. After exposures of more than 1 hour, the volatile organic compound levels were associated with increased 15 minute mean blood pressure and heart rate. The authors conclude that exposure to essential oil aromatherapy for 1 hour can be an effective method of relaxation as indicated by decreases in heart rate and blood pressure. However, prolonged exposure for longer than 1 hour to essential oils may be harmful to cardiovascular health. Eur J PrevCardiol. 2012. PMID: 23197402

Bioavailability comparison of two forms of vitamin K2 (MK-4 and MK-7) This study examined two vitamin K2 homologues, menaquinone-4 (MK-4) and menaquinone-7 (MK-7). Vitamin K2 plays a role in bone health and cardiovascular health and both forms have been used as nutrients in food and as nutritional supplements. This study investigated the bioavailability of nutritional doses when administered to healthy Japanese women. A single dose of MK-4 (420 ug or 945 nmol) or MK-7 (420 ug or 647 nmol) was administered in the morning to participants together with a standardized breakfast. MK-7 was

well absorbed and reached maximum serum level after 6 hours of intake and was detected up to 48 hours after intake. MK-4 was not detectable in the serum of all subjects at any time point.

Consecutive administration of MK-4 (60 ug or 135 nmol) or MK-7 (60 ug or 92 nmol) for one week demonstrated that MK-4 supplementation still failed to increase serum MK-4 levels. Consecutive administration of MK-7 successfully increased MK-7 levels. The authors conclude that MK-4 present in food does not contribute to the vitamin K status as measured by serum vitamin K levels.

MK-7 was significantly associated with increases in vitamin K levels and may be important for extrahepatic tissues. Nutr J. 2012;11:93. PMID: 23140417

Omega-3 polyunsatured fatty acids slow cognitive decline and improve cardiometabolic risk markers This randomized controlled crossover study examined the impact of omega-3 polyunsaturated fatty acids (PUFA) on age related cognitive

decline and cardiometabolic risk factors. Previous studies have not examined the possible relation between cardiometabolic factors and cognitive performance. This study looked at a five week intake of long chain omega-3 PUFA in healthy individuals. 3 grams daily were consumed during 5 weeks, separated by a 5 week washout period in a cross-over placebo controlled manner.

40 healthy middle aged to elderly subjects participated in the study.

Cognitive performance was determined by tests measuring working memory and selective attention. The results showed that omega-3 PUFA supplementation resulted in better performance in working memory tests. The omega-3 PUFA lowered plasma triglycerides and systolic blood pressure. In addition, they also lowered fasting glucose, and s-TNF-alpha and all were inversely related to performance in cognitive tests.

The authors conclude that the intake of omega-3 PUFA improves cognitive performance in healthy subjects after 5 weeks compared to placebo. There is also a potential of dietary prevention strategies by increasing omega-3 PUFA intake in order to delay the onset of metabolic disorders and the associated cognitive decline.Nutr J. 2012;11(1):99.

Health Canada approves Bio-K+® for reduction of C. difficile infections in hospitals

Hospital acquired C difficile infection remains a common cause of morbidity and mortality. An estimated 1% of patients admitted to hospital in Canada acquire C difficile, and an estimated 10% of them die regardless of their basis for admission to the hospital. Bio-K+® is the first natural health product to have a Health Canada approved claim for reducing risk of acquiring C difficile infection. Makers Bio-K Plus International Inc call upon health care providers and hospital administrators across the country to make coadministration of probiotics with antibiotics in hospital settings a standard of care. They estimate adopting such a standard would save the Canadian healthcare system over $200 million per year.

Takeda marks one billion treatments with gastric ulcer drug Pantoprazole

Takeda Pharmaceuticals International recently announced that over one billion treatment courses of its gastrointestinal product Pantoprazole have been administered around the world. Initially launched in 1994 in Germany, pantoprazole is a proton pump inhibitor used to treat acid related disease and is available as a prescription treatment and over-the-counter product. Daily Pantoprazole maintenance therapy for up to 15 years for severe acid-peptic disease is effective and well tolerated.

Historically, no major safety concerns were identified in large clinical trials. No evidence of an enhanced risk for gastric carcinoma has been observed in assessments of laboratory and histological parameters.

Canadian surgical first to remove cancer from the liver At the London Health Sciences Centre, Dr. Roberto Hernandez-Alejandro completed the first of a two stage surgery to remove cancer from the liver.

Formally called an associating liver partition and portal vein ligation for stage hepatectomy, or ALPPS procedure, the surgical first is that both stages of the hepatectomy, or removal of the liver, are completed in one week to ensure that cancer does not spread to other parts of the liver.

Integrated Diabetes Management Program provides rapid improvements in patient care

In Canada, approximately 2 million people have diabetes. The University of Ottawa Heart Institute reported that over 40% of their inpatients are diagnosed with diabetes. As a result, they implemented a program in May 2011 to identify and manage every patient with diabetes admitted as an inpatient.

They trained nurses to serve as diabetes specialists. These champions utilized peer-to-peer training to other nurses, doctors, dietitians, and residents that centered on a new guideline and educational tool box designed to walk staff through the steps to identifying and managing diabetes. A year and a half after initially being implemented, the guideline became a mandatory medical directive. After implementation of the program, 85% of patients had their doctors notified of their diabetic status compared with only 26% before the program. More importantly, the average HbA1c in diabetic inpatients dropped by almost 2%, to the target level considered reflective of wellmanaged diabetes.

The results of an international survey called ‘Mind the Gap’ assessed patients’ and healthcare professionals’ differing perceptions of ulcerative colitis and were presented during the United European Gastroenterology Week. On average, patients reported almost six flare ups in the previous year while physicians reported almost four. Pain was ranked as very important for patients while physicians ranked urgency and stool frequency the highest. These key differences identified that improved communication between patients and their physician or specialist and better patient education would potentially address these issues.

Large genetic study shows evidence of link between inflammation and heart disease

The University of Ottawa Heart Institute participated in the largest genetic study of coronary artery disease to date. The study was published in the scientific magazine Nature. 15 genetic regions were newly associated with the disease, bringing the total to 46. The research team also identified 104 independent genetic variants that are highly likely to be associated with the disease. These discoveries have helped other doctors from the Heart Institute identify biological pathways that underlie the disease and showed that lipid metabolism and inflammation play a significant role. These findings show clear evidence that several of the genetic risk factors for coronary artery disease function through known inflammatory pathways, which could pave the way for developing new therapies.

Study cautions provinces about tendering generic medicines

A new study called “Tendering generic drugs: What are the risks?” was commissioned by the Canadian Generic Pharmaceutical Assocation (CGPA). According to the study, tendering generic drugs in Canada could cause many negative consequences such as potential drug shortages because of less redundancy in the drug supply system, less manufacturing of generic drugs in Canada, less customer services offered by generic suppliers to pharmacies, the closure of some pharmacies, and others. The study discusses how tendering removes the incentive for generic pharmaceutical manufacturers to mount legal challenges to invalid or non-infringement patents on brand-name drugs. The authors argue that tendering has important implications and is only one of the approaches that can be used to procure generic drugs.

New treatment for Obstructive Sleep Apnea available in Canada

Ventus Medical has announced the introduction of its proprietary Provent Sleep Apnea Therapy into Canada. Provent Therapy is an innovative, non-invasive treatment for obstructive sleep apnea. This is a scientifically validated and user-friendly approach that uses nasal expiratory positive airway pressure to keep a patient’s airway open during sleep.

Over 1 in 4 Canadian adults are at high risk of obstructive sleep apnea. Continuous positive airway pressure is the primary treatment, but not all patients can tolerate it as a long term treatment. Provent Therapy improved quality of sleep while reducing sleep apnea, daytime sleepiness and snoring in clinical studies in the US. It is easy to use, portable and discreet for use at home or when travelling.

industry news Health Canada gives nurse practitioners more prescribing authority

Health Canada has published new regulations to grant more prescribing authority to nurse practitioners (NPs), midwives and podiatrists. NPs are registered nurses with additional education, advanced nursing experience, and who work collaboratively with other health care providers. Current legislation and regulation authorize NPs to independently diagnose and treat health conditions, but with limited prescription authority. The new regulations allow NPs across Canada (except Yukon) to prescribe controlled substances under the federal Controlled Drug and Substances Act. This will help to provide more timely and comprehensive care to patients.

First public information service devoted to gut microbiota now online

Gut Microbiota World Watch is a new online platform aimed at increasing knowledge and understanding of gut microbiota and its importance for health and quality of life.

The intestines are populated with a universe of lifeforms called gut microbiota that perform a variety of vital functions, including functioning as part of the immune system.

Launched by the Gut Microbiota and Health section of the European Society of Neurologastroenterology and Motility, this public information service will provide the latest news about gut microbiota. It will act as a point of reference for gut microbiota issues and offer information in straight-forward and easy to understand language. The composition of gut microbita is unique to each individual and evolves throughout the entire life. It is affected by external factors, including conditions of birth, diet, environment, or use of antibiotics. The information service can be accessed at gutmicrobiowatch.org.

ENDECE Neural presents remyelination findings at 2013 Biotech Showcase

Dr. James Yarger, CEO of ENDECE Neural, will discuss the company’s novel therapeutic for directly inducing remyelination of demyelinated axons to treat neurological diseases such as Multiple Sclerosis (MS). Currently there are no drugs commercially available for remyelination in MS, or any other disease associated with demyelination. ENDECE Neural may have one of the first compounds with the ability to directly induce remyelination. This new therapeutic could potentially be used alone or in combination with other immunosuppressant or anti-inflammatory therapies to help restore function and mobility in MS patients.

Potent Antibodies neutralize HIV and offer potential new therapy

Researchers at The Rockefeller University have shown that a therapeutic approach harnessing proteins from the human immune system can suppress HIV in mice without need for daily application. Five different antibodies effectively suppressed HIV-1 replication and kept the virus at bay for 60 days after termination of therapy, which has a longer half-life. These potent antibodies were recently discovered.

Called broadly-neutralizing antibodies, they were identified and cloned from HIV patients whose immune systems had a high ability to neutralize HIV. Recently, these antibodies have also been shown to prevent HIV from infecting non-human primates, leading to the potential for a vaccine in humans.

Breast milk probiotic launched in Australia: world first

Biosearch Life’s Hereditum probiotic strain Lactobacillus fermentum Lc40 is being sold in sachet form and it is marketed for pregnant and breastfeeding mothers. Studies have shown that certain strains of probiotics such as this one can improve the immune system of the mother and infant. In addition, it can prolong breastfeeding by reducing the incidence of mastitis, which the World Health Organization ranks as the number one reason mother’s cease breastfeeding.

The probiotic is being sold under the name Qiara and is being endorsed by some professionals as an alternative to antibiotics that have proven ineffective in some situations due to drug resistance in breastfeeding women.

New drug targets aggressive Non-Hodgkin’s Lymphoma

An international research team led by two laboratories from Weill Cornell Medical College have developed a new experimental drug to target an aggressive form of lymphoma, called activated B-cell diffuse large B-cell lymphoma (ABC-DLBCL). An experimental small molecule agent called MI-2 irreversibly inactivates a key protein, MALT1, that is responsible for driving the growth and survival of lymphoma cells. In their study, the researchers showed that the MI-2 inactivates any MALT1 it comes into contact with and also does so without any apparent toxicity in animal models.

Social Media changing the behaviour of health care practitioners

A recent study analyzed the factors that influence the adoption and use of social media by physicians to share medical information. The authors developed a survey that was emailed to 1695 practicing oncologists and primary care physicians in the United States. Responses from 485 physicians were analyzed. Overall, almost one in four physicians used social media daily or many times daily to scan or explore medical information and 14% contributed new information through social media. Physicians largely had favourable attitudes toward the use of social media and most perceived social media to be beneficial, engaging, and a good way to get high-quality information. A majority of the physicians also identified that social media enabled them to care for patients more effectively and improve the quality of patient care they delivered. The main factors influencing physician’s usage or share information was perceived ease of use and usefulness.

testosterone to DHT (which is the primary molecule that causes hair loss). The SDG from flax lignans in both formulas also decreases excess cholesterol - the building block of testosterone. Based on new research on the rate of metabolism of SDG in flax lignans (8-12 hours on average), the dosage in both products has been revised from once a day to twice a day for optimum results.

Twice the Strength! Double the Power!

Bio-Fen® Plus for Men: The mechanism that causes AGA in men follows the same pathway that results in benign prostatic hyperplasia (BPH). For example, the prescription drug finasteride also works by blocking the enzyme 5αreductase and is used as a treatment for both BPH and AGA. For AGA it is marketed under the brand name of Propecia, but the exact same molecule for BPH is sold under the name of Proscar.

Hair Grow Technology’s Bio-Fen® product line is continually moving forward! We are introducing our two latest versions; Bio-Fen® Plus for Men and Bio-Fen® Plus for Women. These products have been assigned Natural Product Numbers (NPN’s) by the Natural Health Products Directorate (NHPD) of Health Canada.

We recognize that both men and women experience androgenic alopecia (AGA, or male / female pattern baldness) and have made some improvements to the original formulation based on the latest science to address their specific needs. You will notice that we now have additional complementary (Health Canada Approved) health claims on each product.

What causes hereditary hair loss?

Each hair grows from a pocket in the skin called the hair follicle.

During its growing phase the follicle has a bulb-shaped bottom, the center of which is called the dermal papilla. The paplla is fed by very small blood vessels, which bring it food, oxygen and remove wastes.

The papilla is highly sensitive to hormones and chemicals secreted by the body (or ingested as a medicine) which impacts hair growth It is believed that some individuals have a genetic predisposition to a receding hairline (most common in men) or hair (follicle) thinning over larger areas of the scalp (more common in women). These conditions result from hormonal changes caused by an enzyme in the dermal papilla called 5-alpha-reductase. This enzyme breaks down the hormone testosterone into dihyrotestosterone (DHT). Over a period of time, an over abundance of DHT causes the hair follicle to degrade and shortens the active phase of the hair, eventually leading to thinner hair and eventual hair loss.

How does Bio-Fen® PLUS work?

We are bringing you two new products with double the number of capsules and triple the number of health claims for men and four times the number of health claims for women, As in the previous formulation, the fenugreek seed extract in both new formulas reduces excess blood lipid levels (hyperlipidemia). Fenugreek contains β-sitosterol, an active plant sterol, which has been shown to inhibit 5-alphareductase activity – the enzyme responsible for converting excess

As before, the saw palmetto extract inhibits the enzyme 5-alpha reductase, and this action slows down the conversion of testosterone to dihydrotestosterone (or DHT) – the overabundance of which causes the miniaturization of hair follicles. This activity of the saw palmetto also helps to relieve the urinary symptoms of mild to moderate BPH for men.

The saw palmetto that originally was an extract standardized to 45% free fatty acids, esters, and sterols while the new formula is a 4:1 extract to support the BPH claim. The product still contains these molecules for hair loss, but they are now at proprietary amounts based on our research so that the competition cannot duplicate our formula.

Bio-Fen® Plus for Men will also help to: • Relieve the urologic symptoms associated with mild to moderate benign prostatic hyperplasia - BPH (e.g. weak urine flow, incomplete voiding, frequent daytime and night time urination).

• Reduce elevated blood lipid levels / hyperlipidemia.

Bio-Fen® Plus for Women: The women’s formula is almost the same as the men’s formula. The mechanisms and results for the women formula is the same. The only difference is it contains silicon and iron instead of saw palmetto.

Silicon has been shown to contribute to hair shaft strength and thus healthy hair growth. It also contains iron which helps prevent iron deficiency. A number of studies have related sub-clinical iron deficiency in women to diffuse hair loss/alopecia.

The increased amount of SDG and other revisions to the regulations allow us to make some additional health claims for Bio-Fen® Plus for Women.

•

Bio-Fen® Plus for Women will also help to: • Reduce elevated blood lipid levels/hyperlipidemia • Prevent iron deficiency.

• Metabolize carbohydrates, fats and proteins.

How long must I use Bio-Fen® Plus?

Bio-Fen® Plus for Men capsules are usually effective at stopping hair loss within the first two months. However, since healthy hair grows only about 1 cm each month, it may take up to three months before you notice that hair growth is increased or the rate of hair loss is decreased. Anyone experiencing new growth should see it within four months. In some people the original pigmentation may come back.

Once you stop completely your hair growth pattern will slowly go back to the point where you started. However, some people may be able to go with a lower maintenance dose.

Why has the recommended dose doubled?

Based on new research on the rate of metabolism of SDG in flax lignans (8-12 hours on average), the dosage in both products has been increased to twice a day for optimum results. The flax lignan extract in the original formulation was 100 mg standardized to 20% SDG x 1 capsule per day, which equaled to 20 mg/day of SDG. The new formulations have 200 mg per capsule of flax lignan extract standardized to 50% SDG x 2 caps/day equals 200 mg/day of SDG. As such, one is getting 10 times the amount of SDG per day!.

How safe is Bio-Fen® Plus?

The ingredient combination in Bio-Fen® Plus is generally safe for most adults. However, the following cautions are advised: For Men: Consult a health care practitioner prior to use to exclude a diagnosis of prostate cancer, or if you have diabetes. For BPH or elevated blood lipid levels, consult a health care practitioner if symptoms persist or worsen. People sensitive to niacin may experience flushing of the skin that is generally mild and transient. Discontinue use if you experience hypersensitivity to flax, such as an allergy (may occur in rare cases).

For Women: Consult a health care practitioner prior to use if you are pregnant or if you have diabetes. Consult a health care practitioner if elevated blood lipid levels persist or worsen. People sensitive to niacin may experience flushing of the skin that is generally mild and transient. Discontinue use if you experience hypersensitivity to flax, such as an allergy (may occur in rare cases). Because of the iron content, some people may experience constipation, diarrhea and/or vomiting. Keep out of the reach of children. There is enough iron in this package to seriously harm a child.

Call for Nominations 2013 Do you know someone who has made a significant contribution to the field of Complementary & Alternative Medicine in Canada?

Nominations are now being accepted for the $250,000 Dr. Rogers Prize for Excellence in Complementary & Alternative Medicine Nominations close: Friday, May 31, 2013, 5:00 pm PST

Prize to be presented at the Gala Award Dinner in Vancouver, BC on Thursday, September 26, 2013 Nominations and information: www.drrogersprize.org

20 13 Dr. Roger Prize Recipients Catalysts in the Field of CAM $250,000 Prize realizes exponential impact in the future of health care The Dr. Rogers Prize highlights the important contributions of complementary and alternative medicine to health care. Awarded biennially, it is intended to recognize and reward people who have made significant contributions in the field. The largest prize of its kind in North America, the first Dr. Rogers Prize was awarded in 2007.

True pioneers in CAM, previous recipients of the prize have used the award to continue their groundbreaking work. Dr. Hal Gunn and Dr. Badri Rickhi, co-recipients of the 2009 prize, have each used the award to further research in their respective fields. Dr. Gunn, co-founder of InspireHealth, has utilized the funds for the Research Department at InspireHealth, as well as the development and research of Site Specific Immunotherapies, a novel cancer immunotherapy treatment that stimulates that body’s innate immune system. Having achieved success with a spiritual approach to treatment of adult depression, Dr. Rickhi, Research Chair at the Canadian Institute of Natural and Integrative

IHPAPR2012_XXXX_ADVERTISER_Product_FP.indd 1

Medicine, has used the prize to develop and test a similar internetbased approach to treating adolescents. Dr. Rickhi firmly believes in keeping an open mind in the treatment of illness. “If we stay in the box, what we’re trying to do is become better technicians. If we go outside the box – for me – that is what being a scientist is about.”

2011 winner, Dr. Marja Verhoef, Research Chair in Complementary Medicine at the University of Calgary recognizes the importance of collaboration and is passionate about Whole Systems Research. She will use the Prize to improve the quality of CAM research and the CAM research training opportunities.

“CAM treatment systems can only be done justice by research that acknowledges their complexity and the interconnectedness of the various treatment elements,” says Dr. Verhoef. “It is not acceptable to say that we don’t have such methodological approaches. If that is so – we need to develop them.”

UBQHTM, a patented form of ubiquinol in an exclusive, clinically studied delivery system Integrative TherapeuticsTM introduced the first stable ubiquinol product to the practitioner market in 2006. UBQH supplementation results in a greater sustained plasma level of total CoQ10 than traditional CoQ10 supplementation.* For many patients, supplementation with CoQ10 is not enough.

Genetic predisposition and aging can limit the bodyâ&#x20AC;&#x2122;s ability to convert ubiquinone (CoQ10) to its active form, ubiquinol (QH).

With UBQH, the potential is limitless.

TECHNICAL DATA

Description

Coenzyme Q10, or CoQ10, is dynamically cycled between two stable states: ubiquinone, the fully oxidized (energy supporting) state that shuttles electrons, and ubiquinol, the fully reduced (antioxidant) state that releases electrons. Ubiquinol is an extremely unstable compound and converts to ubiquinone upon exposure to light or oxygen.1 However, research has led to the development of a method to stabilize ubiquinol. UBQH contains Kaneka QH™, patented (US10/501,698 US Appl. # 20050147598), stabilized, active ubiquinol.2 Studies have shown that in older individuals, supplementation with stable ubiquinol resulted in greater sustained plasma levels of the active form of CoQ10 (ubiquinol).3

Background

CoQ10, an essential component of cellular energy production, was first isolated from beef heart mitochondria in 1957 by Frederick Crane, PhD at the University of Wisconsin Enzyme Institute.5 In 1958, a team of researchers led by Karl Folkers, PhD determined the precise chemical structure of CoQ10 (2,3 dimethoxy-5 methyl-6 decaprenyl benzoquinone), synthesized it, and successfully produced it by fermentation.6 That same year, another team of scientists led by RA Morton, PhD isolated the same substance from mitochondria and named it ubiquinone because of its widespread (ubiquitous) occurrence in nature.7

How It Works

Most of the cells in the human body contain mitochondria, small organelles that make adenosine triphosphate (ATP), the energy-rich compound that fuels the body’s activities. The synthesis of ATP within the mitochondria is a highly complex, multi-stepped process involving a series of biochemical reactions called the electron transport chain.9 As ATP cannot be stored, it must be replaced as it is used.

This means that ATP production is an ongoing event. While ATP can be produced by a number of distinct cellular processes, the majority of ATP is generated by the electron transport chain.8,10 CoQ10 is a natural nutrient that’s found in the mitochondria. Called a “coenzyme” because of its unique ability to participate in chemical reactions and remain unchanged, CoQ10 assists in two vital cellular activities: ATP production and free radical scavenging.*8 To carry out these activities, mitochondrial CoQ10 continuously cycles from ubiquinone, its ATP production state, to ubiquinol, its antioxidant free radical scavenging state.*11 As previously stated, the generation of ATP within the electron transport chain is a complex process.

Each step results in the building up of energy. Ubiquinone contributes to ATP production by the shuttling or transporting of electrons. Similar to people in a bucket brigade passing buckets of water to one another, ubiquinone passes electrons from one enzyme complex to another.12 To meet the considerable energy needs of cellular activities, the electron transport chain makes considerable quantities of ATP.7 The electron transport chain also creates an enormous amount of free radicals – about 1 trillion oxygen radicals per cell every day. Most of these oxygen radicals are contained within the membrane folds of the mitochondria; however, about two percent are able to get free, generating toxins that present a significant danger to the entire cell.*13,14,15 The antioxidant form of CoQ10, ubiquinol, scavenges free radicals within the mitochondria and cell membranes.1 While free radical formation is harmful to all cells, it is especially dangerous to cells with high biologic activity, such as heart and brain cells.* The highest concentration of CoQ10 is found in cardiovascular (heart) and nervous system (brain) cells to protect their vital functions.*10,11 Ubiquinol is an important antioxidant because it is present at sites where free radicals inflict significant damage.*1,5,7 While more than 90 % of the CoQ10 found in a healthy person’s plasma is in its reduced form, ubiquinol is highly unstable and reverts back to ubiquinone when it is exposed to air and light.16 This is why, until very recently, only ubiquinone has been available in supplement form. The process of stabilizing ubiquinol outside of the body took several years to test and perfect.17 The KanekaQH in UBQH ubiquinol has the innate ability to be absorbed more efficiently than ubiquinone. While supplemental CoQ10 must be cycled to ubiquinol for absorption, the Kaneka QH in UBQH is able to avoid this reduction reaction as it is already in the reduced state. UBQH is especially helpful for those individuals whose DNA cannot properly process CoQ10 or those that are experiencing a natural decline in CoQ10 production associated with aging.*

Scientific Research

When individuals have substandard plasma levels of (total) CoQ10 (<2.0 g/ml), CoQ10 supplementation frequently fails to provide an adequate therapeutic response, even at doses up to 900 mg/day.*18,19 Many individuals respond poorly, if at all. A study by Watson demonstrated a mean plasma CoQ10 level of only 1.7 g/ml in the treatment group with only two of 30 patients (ages 18-75 years old) having a level greater than 2.0 g/ml.18 The Khatta trial, which included fifty-five participants (mean age=64 years), demonstrated a mean plasma CoQ10 level of 2.2±1.2 g/ml indicating that some patients on treatment had levels as low as 1.0 g/ml.19 A recent clinical study of seven adult men and women (ages 58-78) with low serum CoQ10 levels (mean level 1.4 g/ml) and corresponding left ventricular output decreases investigated their response to Kaneka QH supplementation.4 Follow-up data showed an increase in mean plasma CoQ10 levels from 1.6 mcg/ml to 6.5 mcg/ml, as well as an improvement in left ventricular function from 22% up to 39%.

A 2011 study demonstrated the ability of ubiquinol to support healthy lipid metabolism.*20 The study included 53 healthy men who were given 50 mg of Kaneka QH ubiquinol three times daily for two weeks. The researchers reported that supplementation with ubiquinol was shown to support healthy LDL cholesterol metabolism.* In an experiment which used an animal model of aging, ubiquinol supplementation was associated

Total CoQ10 measurement consists of the sum of both ubiquinone and ubiquinol levels. For most people, the Total CoQ10 measurement is approximately 97% ubiquinol and 3% ubiquinone.

This large body of evidence has established that CoQ10 supplementation can improve cell energy production and extend cell life by enhancing cellular mitochondrial levels of CoQ10, thus supporting all physical systems, including support of cardiac, neurological, periodontal, skin, and immune health.* It has also been previously demonstrated (through research utilizing Integrative Therapeutics’ Vitaline CoQ10) that supplementation with coenzyme Q10 raises serum and mitochondrial levels of CoQ10, thereby supporting healthy cellular respiration.*

In the late 1970s, CoQ10 research dramatically increased as the technology to produce large quantities of pure CoQ10 was perfected and the ability to accurately measure its presence in blood and tissue samples was developed. To date, CoQ10 has been the subject of more than 4,000 studies, eleven international conferences, and, in 1978, the Nobel Prize in Chemistry. British biochemist Peter Mitchell, PhD was awarded the Nobel Prize for his contribution to the understanding of biological energy transfer which includes the vital role of CoQ10 in energy transfer systems.8

with healthier aging (as determined by skin, eye, skeletal and general health) in comparison to aging in the both the CoQ10 and control group.*21 The control group in this experiment experienced double the senescence scores in mid-life when compared to the ubiquinol group, while the CoQ10 supplemented group had senescence scores approximately 1.5 times as high as the ubiquinol group.* Increased senescence scores are an indication of the signs of aging.*

Stability and Safety

The safety, absorption, and bioavailability of ubiquinol have been established. Acute toxicity and safety studies of ubiquinol including genotoxicity tests, Ames, chromosome, and micronucleus tests have all been negative.21 In a recent placebo-controlled safety trial, single doses of Kaneka QH were given to 15 healthy volunteers (5 males and 5 females for the 150 mg dose and 5 males for the 300 mg dose).22 No safety concerns were noted, no changes in standard laboratory tests were observed, and no adverse events were reported in doses of up to 300 mg for up to two weeks after the study’s completion. In the bioavailability arm of the study, 78 healthy volunteers (10 males and 8 females each for placebo, 90 mg, 150 mg, and 300 mg dose groups) received Kaneka QH for 4-weeks. No clinically relevant changes induced by Kaneka QH were noted in the subjects’ standard laboratory tests, physical examination, vital signs, or electrocardiograph (ECG) readings in any dosage group.

Conclusion

Kaneka QH in UBQH is the same form of CoQ10 that is present in over 90 % of the human bloodstream.16 UBQH would be appropriate for older adults, individuals presenting with NQ01 genetic inefficiencies, or those requiring higher doses of CoQ10 due to conditions that are associated with reduced blood CoQ10 levels.* Requiring no conversion from ubiquinone to ubiquinol, UBQH is ready to support nervous system and cardiovascular health in these populations.*

Dr Erika Schwartz, MD

Dr. Erika Schwartz is the go-to physician for all types of healthcare providers looking to train in prevention and wellness. In that context she is perhaps best known for her role as physician educator in the methodology and science of bioidentical hormone replacement therapy for prevention and wellness. Her career, however, started in a very different area of medicine. At the age of 28, Dr. Erika was the Medical Director of a major trauma centre in New York City. Five years later she went into the private practice of internal medicine and developed a highly successful practice for the following Training integrative healthcare fifteen years affiliated with three hospitals and on the providers for delivery of board of a New York medical school. What lead this respected, classically- trained physician to seek Bioidentical Hormone Therapy wella new approach to patient management? “I didn’t like

By Philip Rouchotas MSc, ND the style of medicine I was practicing... everything was disease focused... I was waiting for people to get sick Photography by Babar Khan while doing testing and sending them home to wait for something to go wrong”, was her reply.

cover story Dr. Erika’s career path is as unique as the life path that brought her to her current position.

Born in Bucharest, Romania, she graduated from an American high school in Rome, then off to the “Big Apple” to attend college and medical school in New York City. Graduating from medical school in 1975, Dr. Erika’s internship, residency and fellowship focused on internal medicine and critical care, all disease centered practices. Twenty years into the practice of this conventional type of medicine, Dr. Erika found herself asking more questions than the system had answers for... By the early 1990’s, her interest in prevention was firmly established.

Dr. Erika researched physicians in New York and California that were engaged in the practice of integrative medicine and found few credible resources and no formal training available in the area. Dr.Erika found herself spending countless hours researching available data and training in the practices of integrative medicine. Her role today as a leading educator in prevention and bioidentical hormones for clinical practitioners stems from Dr. Erika’s personal frustration with the lack of quality education and training in areas considered outside conventional medicine.

Erika has written a highly successful series of books aimed at educating the general public on principles of wellness and disease prevention. Her first book, entitled Natural Energy (From Tired to Terrific in 10 Days) (1999) reviewed and highlighted the importance of CoEnzyme Q10 and Lcarnitine in fighting fatigue. We at IHP are in total agreement that these two agents are crucial in maintaining healthy mitochondrial function, an area receiving more and more attention as the focus of care shifts to health maintenance rather that disease treatment.

Dr. Erika attributes tremendous importance to hormone balance as a means of preventing chronic diseases in the 21st century. “Running out of hormones is unhealthy. Using human identical hormones as replacement opens the door to true disease prevention. Prevention strategies are likely to fail if people feel drained, exhausted, depressed, and generally unwell.

Using human identical hormones to create much needed hormone balance leads to improved mood, energy, and general well being allowing a person to be able to address the multiple lifestyle factors (diet, exercise, sleep) responsible for disease prevention”.

Dr. Erika’s second book was published in 2002, and we feel it important to point out it was published three months before the results of the Women’s Health Initiative study demonstrated the use of synthetic (pregnant horse urine) estrogen as a source of higher risk for heart disease, strokes and cancer. In her book, The Hormone Solution, Dr. Erika raised concerns about synthetic hormone replacement therapies (estrogen derived from pregnant mare’s urine), while highlighting the advantages of human identical hormone therapy (also known as bioidentical or natural hormones) and discussed the impact on overall health when individualized hormone therapies are provided for each patient. In 2004 Dr Erika authored her next book “The 30 Day Natural Hormone Plan”, reinforcing the importance of hormone health and simultaneously providing useful tools for implementing health sustaining plans for diet, exercise, relationships, and sleep. In 2007 Erika published Hormone Solution for your Daughter, which showcased the role of hormones in balancing the health of teenagers, and reviewed important skills for parenting, diet, exercise, relationships and sleep.

Treatment with bioidentical hormones has witnessed various methods of usage. Dr. Erika applies a concept of therapy we found incredibly unique; unlike the conventional approach of “treat to a target blood level”, Dr.Erika adopts the approach of “treat until the person feels well and then assess blood levels. Those are then the target blood levels for the individual in question”. It is an approach that may result in “higher than typically used in compounding ” levels of hormones being prescribed, yet is an approach that is truly individualized, and inherently identifies each patient’s particular optimum hormone levels. The approach may be applied to a broad array of treatment plans, not isolated to the application of bioidentical hormones.

cover story

Dr. Erika has emerged as a leading authority in the education of healthcare providers. In 2007, along with a few other key opinion leaders in the field of prevention she founded the not for profit organization Bioidentical Hormone Initiative www.bhionline.org www.bioidenticalhormoneinitiative.org Through this organization and its affiliation with a New York medical school, Dr. Erika is able to offer practitioners clinical in office and seminar format training on the use of bioidentical hormone therapy. The seminars Dr. Erika teaches are not just about how to use bioidentical hormones in your practice; they are powerful examples of patient advocacy, and a tremendous and effective tool in bridging the gap between conventional and integrative healthcare providers.

The seminars attract practitioners from all disciplines leading to successful much needed inter-professional relationships that result in truly integrative care for the patients and mutual respect and information sharing.

Dr. Erika has a new book in the works. The book focuses on helping patients take responsibility for their own healthcare by giving them the tools and confidence necessary to avoid bad medical decisions. “The book is intended for the public, yet delivers an important message to physicians as well; physicians need to change their attitudes. They have to become patient partners and serve the patient rather than their own egos. The book teaches patients to take responsibility for their own care, to trust themselves and not allow others to dictate their path to wellness. Ultimately, there is no reason to be sick!” she affirms.

IHP is grateful to Dr. Schwartz for taking the time to allow us to showcase her work to you. Dr. Erika is an incredible, energized, brilliant physician whose presence motivates you to ask yourself “what else can I do to help others”... Her parting words for me seem an ideal way to end this story: “you are only as good as the last past patient you helped make well”. ■

PRODUCT MONOGRAPH OIL OF OREGANO

Oil of Oregano is a hydrophobic extract of Origanum vulgare leaf. Major active constituents include the monoterpene phenolic compounds carvacrol and thymol. Carvacrol and thymol are potent antimicrobials with synergistic bactericidal, fungicidal, and antihelminthic activity.

Human studies

Oil of Mediterranean Oregano had antihelminthic effects when given at 600 mg emulsified oil per day in 14 adults who had tested positive for enteric parasites Blastocystis hominis, Entamoeba hartmanni, and Endolimax nana. After 6 weeks of treatment, there was complete resolution of parasitic infection in 8 cases, while Blastocystis hominis scores decreased in three more cases; gastrointestinal symptoms improved in 7 of the 11 subjects who had presented with Blastocystis hominis infection. (Force 2000)

Animal and In vitro studies

Carvacrol for oral candidiasis in immunocompromised rats was found to be as effective as treatment with Nystatin, reducing the number of colony forming units (CFU’s) and completely clearing hyphae from oral surfaces when given for 8 days (Chami 2004). In vitro, carvacrol was determined to exert an inhibitory effect against 6 different strains of Candida species primarily due to extensive lesion of the plasma membrane (Salgueiro 2003).

Carvacrol has potent antimicrobial activity against several microbial species, including Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Psuedomonas aeruginosa, Candida albicans, and Aspergillus niger; out of these, Candida albicans has been found most susceptible (Santoyo 2006). Carvacrol and thymol are thought to exert an additive effect by disrupting bacterial membrane integrity (Lambert 2001). Oregano has been shown to inhibit Methicillin resistant strains of Staph.

aureus and epidermis, and attenuates biofilm formation in vitro (Nostra 2004; 2007).

Toxicology

Essential oil extracts are categorically known to be toxic in high doses, and are therefore typically given in drop doses; essential oils should not be used internally by pregnant or breastfeeding women. Animal studies to date, however, indicate relative safety of Oregano oil.

Carvacrol was shown to be hepatoprotective against ischemia and reperfusion injury in rats; both carvacrol and silymarin had similar beneficial effects on AST and ALT levels (Canbek 2007). Carvacrol also increased liver regeneration rate in rats after partial hepatectomy (Uyanoglu 2008).

Mutagenicity studies of carvacrol show only weak activity; carvacrol is excreted in urine after 24 hours in large quantities, unchanged or as glucoronide and sulphate conjugates (De Vincenzi 2004).

HP is proud to introduce Paradigm Health Group, a 2000 square foot integrative medicine clinic in Calgary, Alberta. Dr. Jason Ahlan and Dr. Trevor Hoffman founded Paradigm after working together at the Integrative Medicine Institute of Canada (IMI), a collaboration amongst medical doctors, naturopathic doctors, dentists, and other healthcare professionals. When IMI closed its doors in 2007, these highly enthusiastic naturopathic doctors opened Paradigm with the vision that “by doing what we love, taking care of our patients one at a time, we can translate that to a positive experience for all.”

Dr. Ahlan and Dr. Hoffman recognized that successful individual naturopathic practices can be extremely difficult to establish. Believing that “there is power in numbers”, they opted to build a strong medical practice comprised of six naturopathic doctors with different backgrounds, strengths, and specialities, who are each held to the same level of excellence. Paradigm offers comprehensive care to patients that strongly consists of in-house cross-referrals. In an attempt to provide patients with the best care possible, Paradigm realizes that practitioners must sometimes acknowledge when another practitioner can provide superior care, especially considering the broad range of services offered, including prolotherapy, photoactivated platelet rich plasma injection therapies, nutrient IVs, chelation therapy, ozone therapy, ultraviolet blood irradiation, neural therapy, and mesotherapy. On the horizon, services offered will also include ultrasound guided injection therapies and adipose derived stem cell therapies. Numerous programs are offered that address stress, sleep, cancer, sports medicine and performance enhancement, pain management, autoimmunity, Firstline Therapy (FLT), allergies/sensitivities and related disorders, and detoxification.

Detailed descriptions of these services and programs can be found on Paradigm’s website (http://www.paradigmhealth.ca).

Paradigm strives to offer a wide variety of therapies in an effort to address numerous patient needs.

Paradigm Health Group Leaders in innovation By: Angela MacNeil, MSc, ND

In addition to the naturopathic doctors, the clinic boasts an amazing network of 15 in-house/affiliated medical doctors with different specialities, and a broad referral network that includes chiropractors, massage therapists, physiotherapists, and holistic nutritionists. This network has contributed immensely to Paradigm’s success and the practitioners feel very fortunate to have these ties.

An effective networking strategy employed by Paradigm is the attendance of medical conferences; this serves to further the knowledge base within the clinic while simultaneously increasing contacts. In recent months alone, Paradigm practitioners have attended prestigious conferences world-wide, including the Restorative Medicine Conference, the Ironman Hawaii Sports Medicine Conference, the American College for Advancement in Medicine, and the American Academy of Orthopaedic Medicine. Since naturopathic medicine is a rapidly expanding field, staying on the cutting edge of research requires

clinic profile training from experts around the world.

Admittedly, these conferences are costly to attend but the practitioners note that the education, improved experience, and expanded network they confer are priceless and have had tremendous impacts on the practice’s success.

In addition to a strong focus on continuing education, Paradigm is represented at the Canadian Institute of Natural and Integrative Medicine (CINIM), a registered charitable organization that conducts scientific research in complementary/alternative medicine (CAM).

CINIM was the first of four Canadian institutions to become involved with the United States Consortium of Academic Health Centres for Integrative Medicine whose membership includes 51 highly esteemed academic medical centers and affiliate institutions, including Harvard, Yale, and the Mayo Clinic. Dr. Ahlan is one of only three naturopathic doctors in this collaboration, representing the University of Calgary Medical School. CINIM was developed in response to public demand for information about alternative therapies and access to these therapies.

Several of Paradigm’s practitioners are also involved with the Pure North S’Energy Foundation, a non-profit initiative that focuses on the delivery of innovative preventative and integrative health and wellness strategies. Pure North includes a comprehensive team of expert health and dental care professionals including physicians, naturopathic doctors and nurses that travel throughout Canada providing first-rate personalized services to populations who cannot afford integrative medicine. At last count, this funded program has taken the team to multiple sites internationally, seeing almost 15,000 patients from the firefighters in the Slave Lake disaster, to the Native American communities in Inuvik, to the off-shore oil sites in the North Sea of Scotland.

Paradigm’s practitioners also belong to a wide array of boards and advisory councils that include Winsport Canada, Hockey Canada, Alpine Canada, Bobsleigh Canada, The Calgary Flames Hockey

Club, College of Naturopathic Doctors of Alberta (CNDA), and the Competancy Committee for Restricted Activities for the CNDA. Paradigm offers patients a broad range of evidence-based diagnostic tests to verify clinical diagnoses and treatment of various health challenges.

Diagnostic testing is offered from Rocky Mountain Analytical, Doctor’s Data, PharmaSan Labs, NeuroScience, Genova Diagnostics, Metametrix, and Meridian Valley. Paradigm practitioners consider themselves fortunate as the majority of their patients receive blood work through affiliated medical doctors as part of diagnostic work-ups. The clinic also offers a dispensary that features the best products from a variety of companies, including AOR, Douglas Labs, Metagenics, Priority One, Restorative Formulations, Bioclinic Naturals, BioMed, Genestra, Vitanica, Pascoe, and Heel.

60 patients per day. Paradigm has also fully transitioned to electronic medical records (EMR) and despite the large financial investment and steep learning curve, this has opened many doors for the clinic. Although patient records are paperless, all new patients receive a binder that outlines the clinic’s comprehensive referral network, patient expectations, and success stories. Believing that marketing starts at home, Paradigm attempts to offer services of value, and this means taking care of each and every patient first. Consequently, word of mouth is Paradigm’s most powerful marketing tool.

IHP is thoroughly impressed with the success Paradigm has achieved and is thankful that we were given a glimpse into this cutting edge practice. A nice way to conclude is reiterating a statement from Dr. Ahlan: “[you] must follow what you love, by doing that you will always be successful." ■

When Paradigm was established, a focus was placed on billable square feet so that all 10 treatment rooms are full at all times. As a business model, Paradigm focuses on maximizing efficiency, running approximately 100 intravenous treatments per week and seeing roughly

Neurodegeneration

R

eceiving a diagnosis of Alzheimer’s disease, or Parkinson’s, is to most as devastating and fear- provoking as the experience we immediately associate with a cancer diagnosis. Typically symptoms are already present, and it doesn’t take out tech-savvy elders long to learn the prognosis of such a condition. This issue of the journal includes a review of the emerging roles of medium chain triglycerides in Alzheimer’s management from a frequent contributor, William R Ware. We are also grateful to present Part I of a twopart series on CRP-40 from an esteemed team of neuropsychiatry researchers from McMaster University, as their paper bring us up-tospeed on molecular chaperones. Part II delves into unique and exciting prospects for the not-to-distant future application of these molecules in neurodegenerative disease treatment.

Heidi Fritz provides a thorough review of the role of DHEA in improving fertility outcomes in women. Colin MacLeod, a rare and welcomed East Coast contributor provides the issues continuing education lesson with an excellent review of an array of clinical applications for oral and IV administration of N-acetyl cysteine.

Medium Chain Triglycerides (MCT’s)

An alternative approach to the treatment of Alzheimer’s disease William R Ware, PhD Faculty of Science University of Western Ontario London, Ontario, Canada warewr@rogers.com

If one takes a realistic view, modern medicine appears to have little of real significant to offer patients with Alzheimer’s disease.

Treatments are symptomatic and do not significantly decelerate or prevent progression. Behavioural and psychiatric challenges of great concern to caregivers are attacked with powerful drugs not approved for these indications, and have serious and sometimes permanent adverse effects. A new approach appears desperately needed. While it has been known for decades that Alzheimer’s diseases is associated with impaired cerebral glucose metabolism, only recently has this observation begun to attract serious attention and now some even call Alzheimer’s disease Type 3 diabetes. This article addresses therapeutic approaches to cerebral hypoglycemia which directly or indirectly involve providing an alternative brain fuel to counteract decreased glucose metabolism. The alternative fuel consists of ketone bodies produced by ketogenesis in the liver. Clinical studies and limited randomized controlled trials have provided evidence for both the biological plausibility of this alternative approach and its efficacy and safety in the treatment of mild cognitive impairment and Alzheimer’s disease. In addition, what appear to be highly satisfactory oral precursors of the required ketone bodies are natural products readily available in many health food stores. This has generated considerable anecdotal evidence recently reviewed in a book by a respected physician that makes an important contribution to this field.

Introduction Mainstream medicine treats early to moderate stages of Alzheimer’s disease (AD) with cholinesterase inhibitors (Aricept, Exelon, Razadyne and rarely Cognex).

For moderate to severe stages, memantine (Ebixa), a drug that regulates the activity of glutamate, a chemical involved in learning and memory, is frequently employed. While aggressive combination therapies can produce small decreases in the frequently relentless increase of dementia or deteriation in daily living scores, progression remains (Atri 2008).

“Currently available treatments for AD are symptomatic and do not decelerate or prevent the progression of the disease” (Herrmann 2011). There is considerable support for this view (Farrimond 2012, Galvin 2012, Lanctot 2009, Popp 2011).

“Modern medicine appears to have little of real significant to offer patients with Alzheimer’s disease.”

In the US there are no drugs approved for dealing with behavior and psychiatric challenges associated with AD which cause significant problems for caregivers. However, the whole arsenal of antidepressants, anxiolytics and antipsychotics are widely used off-label. The problems and side effects associated with these drugs, both transient and permanent, can be significant (Breggin 2008). While these drugs modify symptoms, their adverse effect profile casts doubt on their true utility. Conventional therapies and the small changes they can affect provide false hope (Breggin 2008, Herrmann 2011). A new approach seems desperately needed.

The Brain Hypometabolism Hypothesis There is growing interest in this hypothesis, initiated in 2005 by Suzanne de la Monte, that Alzheimer’s disease and type 2 diabetes have a number of pathologic features in common (de la Monte 2005). It was suggested that impaired glucose metabolism and impaired

insulin action in the brain, which in part leads to mitochondrial dysfunction and decreased energy production, could be significantly responsible for the pathology observed as AD develops. This led to the suggestion that AD be called Type 3 diabetes. However, the notion that there is a connection between AD and decreased glucose metabolism (hypometabolism) in the brain goes back at least several decades (Hoyer 1970), and there is growing interest in this phenomenon (Yao 2011). Abnormalities in metabolism have been linked to brain insulin and insulin-like growth factor resistance with disruption of signalling pathways that regulate neuronal survival, energy production, gene expression and brain plasticity (de la Monte 2012b). The use of PET scans with a metabolic tracer have provided significant and extensive evidence supporting the presence of hypometabolism and the notion of Type 3 diabetes, and its mechanistic details are the subject of current research (de la Monte 2012a).

A recent review of brain hypometabolism (Cunnane 2011) points out the potential for a vicious cycle generated by brain damage associated with hypometabolism. The authors suggest that this cycle can be effectively broken by sustained improvement in brain metabolism, which can be achieved with ketone bodies acting as replacement fuel. Brain hypometabolism now appears to be an attractive target in AD therapy (Costantini 2008) Ketone Bodies--A Replacement Brain Fuel The three so-called ketone bodies are water soluble compounds (acetone, acetoacetate and beta-hydroxybutyrate) produced in the liver from fatty acids (ketogenesis). Ketone bodies bypass insulin controlled cellular entry and can serve as energy sources in the mitochondria of tissues including the brain.

It was once accepted that upon weaning, the brain was limited solely to glucose for metabolic energy. This view has changed as the neuroprotective potential of ketone body administration has been shown for neurodegenerative conditions, epilepsy, hypoxia/ischemia and traumatic brain injury,

and that there is an age-related therapeutic potential for ketone bodies as an alternative substrate (Prins 2008, White 2011). Also dietary ketosis has been shown to enhance memory in mild cognitive impairment, and there is evidence of protection against neuronal insults, an increase in metabolic efficiency relative to glucose, and in general such diets appear to some extent to mitigate neurodegenerative mechanisms (Krikorian 2012, Veech 2004). Perspective regarding the role of ketones in brain metabolism can be gained by considering that during starvation or very low carbohydrate intake, the liver turns to making ketones (Owen 1967). This defence mechanism evolved eons ago and was likely necessary for human survival.

Starvation is obviously not a practical therapeutic intervention. Neither is a severely ketogenic diet for many patients. Adherence to a classical ketogenic diet is a serious problem since about 90% of energy must come from fat. An obvious solution is an oral supplement or “medicinal food” that provides a source of the needed ketone bodies. Either natural or synthetic medium chain triglycerides (MCT) are obvious sources.

Oral Medium-Chain Triglycerides To Treat Alzheimer’s Disease One of the prominent researchers in the field of brain hypometabolism, Samuel Henderson, was instrumental in the development of a MCT-based product to treat AD called AC-1202, which contained one MCT and could be taken as a dissolved powder. It was patented and tested in several trials and recently a multicenter randomized controlled trial reported (Costantini 2008, Henderson 2009). The compound rapidly elevated serum ketone bodies in patients with AD and resulted in significant improvement in cognitive scores in those with mild to moderate AD when compared to a placebo. MCT oil ingestion has also been found in a placebo controlled study to preserve brain function during hypoglycaemia in intensively treated patients with Type 1 diabetes (Page 2009). Some would consider these results convincing evidence concerning the biological plausibility of the hypometabolic hypothesis.

AC-1202 is available only by prescription and approved by the FDA as a “medicinal food” called Axona.

It contains only one ketone generating MCT. Coconut oil and MCT oil are natural sources generating several ketone bodies and offering flexible dosing throughout the day.

The leading advocate of MCT oil and coconut oil is Dr. Mary Newport, M.D., a paediatrician and director of a neonatal ICU at a Florida hospital. In 2008 her husband had moderately advanced AD that was progressing significantly. She first heard of the use of MCTs for AD in 2008 when she came across reference to Henderson’s patent, found AC-1202 contained a MCT and ascertained that MCTs were present in coconut oil which was available at natural food and health food stores.

She decided there was nothing to lose by trying coconut oil. This was a turning point in her husband’s life as well as hers. Results were remarkably rapid, AD progression apparently stopped, and over the following three to four years many cognitive and behavioural deficits were significantly reduced and many lost functions recovered.

In her words, she “got her husband back.” This is detailed in Dr. Newport’s recent book (Newport 2011).

One of the most fascinating aspects of Dr. Newport’s husband’s change was that initially he was totally unable to draw a clock, a standard test in mental assessment, and a few weeks after starting coconut oil his clock, while not perfect, was significantly improved. This is illustrated in Dr. Newport’s book and in the article on the internet (Newport 2008). In addition, sequential MRI studies revealed that the progression of brain atrophy had been totally halted. It appears that conventional, approved treatments have never produced such a result, or in a significantly sustained manner, any of the above results, especially when the patient has fairly severe AD. Today, most of the interest in this intervention is among lay persons who become aware of MCT oil and coconut oil while doing an internet search for natural AD treatments, through the social media, by word-of-mouth or from Dr. Newport’s book (Newport 2011).

In this book, Dr. Newport provides details and a summary of anecdotal caregiver reports (60 cases) she received after the do-it-yourself treatment became popular. Unfortunately, there is uncertainty as to dose, source of MCTs, adherence, severity of the disease and the quality of reportage from caregivers concerning changes. Nevertheless, 90% of those who tried MCTs were observed to be improved, as indicated by better scores on tests, improved clock drawing, better cognition, more alertness, brighter outlook, improved awareness, less foggy or hazy behaviour, being able again to recognize people or places, being less distractible, and having a better sense of direction.

MCT oil yields higher serum ketone body levels than coconut oil, but the decline over time is more rapid

than seen with coconut oil. Thus coconut oil taken with MCT oil helps smooth out daily fluctuations with higher average levels and coconut oil may have some other benefits not provided by the commercial MCT oils since it contains other fatty acids (Newport 2011). This influenced Newport’s final protocol which involved using an approximately 1:1 mixture of coconut oil and MCT oil at a dose of three tablespoons with each meal and two at bedtime. To avoid diarrhea, the only known adverse effect of MCTs reported, dose escalation is sometimes needed. It is important to note that while attention was paid to a healthy diet, the macronutrient intake of Dr. Newport’s husband was not drastically altered. In fact, the use of MCTs has the advantage of not requiring significant diet changes and can even be used along with conventional treatments.

Ketogenic Diets An alternative to ingesting MCTs is to use a ketogenic diet. Newport claims that the ketogenic diet is capable of producing up to 10 times or more ketone bodies than possible with the doses of MCTs commonly being used, and this becomes an attractive next step for those who do not respond to MCT therapy (Newport 2011).

The ketogenic diet has been used to treat epilepsy and especially patients who failed to respond to antiepileptic drug therapy. The initial interest occurred in the early 1920s and then there was a long hiatus followed by recent renewed interest. There is now considerable evidence of efficacy in epileptic adults and children (Auvin 2012, Lambrechts 2012, Nam 2011). There has also been recent interest in ketogenic diets to treat Alzheimer’s disease (Kossoff 2012, McPherson 2012, Yao 2011).

It has also been found that dietary ketosis enhances memory in mild cognitive impairment (Krikorian 2012).

In addition, improvement in memory impaired adults has been correlated with orally induced increases in the serum level of the ketone body beta-hydroxybuterate (Reger 2004).

There are four recognized major ketogenic diets, the classical diet with 90% of calories from fat, the MCT diet, the modified Atkins diet and the low glycemic index diet. The MCT diet has been used since the 1970s and involves using coconut oil while limiting carbohydrates.

The modified Atkins diet uses a very low carbohydrate induction diet (70% calories from fat, 24% from protein) as the permanent intervention, whereas the low glycemic diet has 45% from fat and 28% from protein with emphasis on carbohydrates selected for low glycemic index (Kossoff 2012).

Conclusions What might be called the alternative fuel approach to treating AD has strong biological plausibility. Limited results from clinical and randomized controlled trials provide evidence of efficacy and safety. Treating hypometabolism with a prescription MCT (Axona) has FDA approval for the indication of cognitive impairment.

When trial data is combined with a large body of anecdotal evidence, the picture emerges suggesting AD patients appear to obtain much more benefit from this alternative approach than from conventional medical therapy.

Individuals with AD frequently have a mixture of vascular and AD-type abnormalities and some have dementia associated with Lewy bodies. Hypothyroidism, micronutrient deficiencies, heavy metal overload, etc., may also contribute to the symptomatic presentation and the alternative fuel approach would not be expected to impact some of these abnormalities. There is also an issue with genetics. In the AC-1202 clinical studies patients not carrying the E4 variant of the apolipoprotein gene (about half of those with AD) showed the highest response (Costantini 2008, Henderson 2009). However, Dr Newport’s husband is ApoE4+ and showed remarkable regression (Newport 2011).

It is disappointing that there is not more clinical trial evidence, but therapies involving natural MCT oil and coconut oil are of no interest to pharmaceutical companies, and the very nature of this therapy invites the criticism of not being adequately evidence based and in fact simply another quack treatment. Those who believe in the future of alternative treatments must recognize the necessity of tolerating these hostile views because meeting the demands of so-called evidence-based medicine will be a slow and frustrating adventure, and individuals with AD and their caregivers may be actively discouraged from trying a therapy with the potential for greater benefit than appears attainable by any other means. Judging by what Dr. Newport reports, many AD caregivers will not settle for what mainstream medicine has to offer and seek to circumvent the hostile attitude of modern medicine. They simply adopt the approach that “What is there to loose? We can do this at home...”; a view directly applicable to MCT therapy. Everything needed is available online or at the local health food store, including a mixture of MCT and coconut oil in the proportions used by Dr. Newport (sold as a salad dressing). Finally, the use of MCTs in primary prevention as one ages remains to be studied but intuitively would appear to have merit.

The Journal of IHP

The website of the company making Axona mentions caution when patients have a history of gastrointestinal problems, metabolic syndrome, uncontrolled diabetes and/or kidney disease. The extent to which these warnings apply to mixed MCT oil and coconut oil is unknown, but Dr. Newport reports only diarrhea.

Guidance and monitoring by a physician is always highly desirable. ■

DHEA

Outcomes in female fertility Heidi Fritz, MA, ND Research Fellow, Canadian College of Naturopathic Medicine hfritz@ccnm.edu Bolton Naturopathic Clinic 64 King St W, Bolton, Ontario, L7E1C7

DHEA and DHEA-S are together the most abundant steroid hormones in the body, and function as weak androgens. In women, DHEA is mainly converted to testosterone, and to a lesser degree estrogen (Buster 1992). Androgen stimulation is thought to play a key role in early follicular development, with androgen receptor deficient mice showing problems with follicular development, ovulation, and ovarian response to gonadotropins that are similar to problems experienced by women with diminished ovarian reserve (DOR). Fuelled by an early case report showing a â&#x20AC;&#x153;dramatic and continuousâ&#x20AC;? (Barad 2005) improvement in ovarian function over an 11 month selftreatment period with DHEA alongside weekly acupuncture, subsequent studies have since shown statistically significant improvements in clinical pregnancy rates, live birth rates, miscarriage rates, increased antral follicle count, number of retrievable mature oocytes and high quality embryos, reduced aneuploidy, and a reduction of IVF cycle cancellations.

DHEA is currently in use as a treatment for DOR, and further investigations are warranted to determine whether DHEA may be of benefit in other related conditions such as premature ovarian failure.

Introduction Dehydroepiandrosterone (DHEA), and its sulphated form DHEA-S, are weak adrenal androgens and the most abundant steroid hormone in the body (Andus 2003).

DHEA acts as a precursor for other steroid hormones in the body, predominantly estradiol and testosterone via androstenedione (Gleicher 2012, Olech 2005). In women, DHEA is mainly converted to testosterone, and to a lesser degree estrogen (Buster 1992, Gleicher 2012).

As a result, DHEA is used as a hormone replacement for older women, in which circumstance it has been shown to benefit bone health (Weiss 2009). DHEA has also been shown to possess anti-inflammatory effects through inhibition of NF-kappaB activation, as well as inhibition of IL-6 and IL-12 secretion via PPAR-alpha (Andus 2003), and has on the basis of this activity been utilized in various autoimmune conditions (Petri 2004, Andus 2003). These applications will be covered in detail in part II of this review. This review focuses on DHEA supplementation as a treatment for diminished ovarian reserve (DOR) and female infertility.

Review of Reproductive Physiology Grynnerup defines the follicle as “the basic functional unit in the ovaries” (2012). The follicle consists of the oocyte in association with surrounding theca cells and granulosa cells; during follicular development, granulosa cells support the maturation of and interact with the oocyte, producing growth factors and hormones to direct follicular development. After ovulation, the granulosa cells become the corpus luteum and secrete progesterone. The number of follicles is set during embryonic development; over the course of a woman’s life, resting primordial follicles are recruited to become growing follicles, a process called initial recruitment that continues until the follicle pool is exhausted (Grynnerup 2012). Growing follicles either undergo atresia (most) or they undergo cyclic recruitment, an ongoing process that begins at puberty, which involves recruitment by FSH. A cohort of follicles is selected with each “cycle” of recruitment, only one of which is selected to become the dominant follicle that will reach ovulation.

Figure 1 depicts the stages of follicular maturation. During early follicular development (pre-antral and antral stages), the granulosa cells secrete anti-Mullerian hormone (AMH). AMH inhibits excessive recruitment by FSH, which would lead to premature exhaustion of the follicle pool (Grynnerup 2012); however, since it is produced by the early pre-antral follicles, AMH can be used as a marker of the remaining growing follicular pool, and by extension the remaining primordial follicle pool, or ovarian reserve (Grynnerup 2012). Similarly, inhibin B is a less studied

but similar marker that is produced during the early to mid stages of follicular development; it inhibits pituitary release of FSH and may also serve as a marker of ovarian reserve (Sill 2009).

The mechanism by which DHEA impacts folliculogenesis is not well defined. Until recently, DHEA was thought to promote follicular development during the very early stages of follicular maturation (Gleicher 2012). This is perhaps surprising since androgens are considered detrimental in other conditions of impaired fertility such as polycystic ovarian syndrome (PCOS).

Nonetheless, evidence based on animal studies shows that androgen receptor mediated function in granulosa cells is crucial to the development of preantral follicles at early stages of development and the prevention of follicular atresia (Gleicher 2012, Sen 2010). In mouse models, androgen receptor knock out animals (ARKO) share striking resemblances with women who suffer from DOR: they become subfertile, have defective folliculogenesis, lower numbers of antral (pre-ovulatory) follicles, fewer corpora lutea, higher rates of granulosa cell apoptosis, and ultimately develop premature ovarian failure (Hu 2004, Kimura 2007, Sen 2010, Shiina 2006, Walters 2007). When subjected to superovulation through gonadotropin administration, these mice ovulate fewer oocytes (Hu 2004).

In humans, intrafollicular androgen levels have been shown to increase granulosa cell AMH (anti-Mullerian hormone) production and decrease inhibin-B levels (Andersen 2008). The authors of this study speculate that this seemingly opposite effect on AMH and inhibin B respectively may reflect a dual activity of androgens on ovarian function: during the early stage of follicular differentiation, androgens induce FSHreceptor expression on granulosa cells, promoting FSH- stimulated follicular differentiation; however in the later (pre-ovulatory) stages, excess androgens may induce atresia of granulosa cells and inhibit LH receptor formation, thus inhibiting ovulation (Andersen 2008). This type of activity does appear to be profiled in conditions of androgen excess most notably PCOS, with hyper-development of follicles but failure of ovulation.

More recently, Hyman et al demonstrated that DHEA therapy was able to improve antral follicle count but not change AMH or inhibin B, suggesting that DHEA does not so much influence the early stages of follicular development (AMH and inhibin B are secreted at these stages) as it increases the rescue rate of the small antral follicles (later stage) from atresia (increased AFC) (2013).

Other earlier studies showed conflicting results with respect to AMH, with one RCT reporting no change

and one retrospective study reporting a large improvement (Gleicher 2010A, Yeung 2012).

It is hoped that more research will be able to more clearly define the mechanism(s) of DHEA. Over the past ten years or so, several investigations into the effect of DHEA supplementation in women with DOR and/ or poor responders to IVF have been conducted, following upon the heels of an initial case series in 2000 and an impressive case report in 2005 (Barad 2005, Casson 2000; both in Table 1). There are only two RCTs among 15 identified studies, in part due to the ethical difficulty of randomizing this particular population, with a highly time-sensitive condition, to an inactive arm (Gleicher 2011).

Instead study designs include prospective, uncontrolled trials and case-control studies in which DHEA- treated cycles are compared to non-DHEA treated cycles in the same group of women.We include all human level interventional evidence pertaining to the treatment of infertility identified in Pubmed up to January 2013, using the terms “DHEA supplementation”.

Diminished Ovarian Reserve (DOR) According to the Society of Assisted Reproductive Technology (SART), DOR does not consist of clearly defined criteria; rather it describes the number and quality of eggs remaining in a woman’s ovaries as assessed or estimated through a number of tests and prognostic factors (Practice Committee 2012).

Initial recruitment

The SART document describes DOR as referring to “women of reproductive age having regular menses whose response to ovarian stimulation or fecundity is reduced compared to those women of comparable age” (2012).

Tests/ factors often used to assess DOR include: day 3 FSH (>10 is considered a poor prognostic) and estradiol; antral follicle count (follicles measuring 2-10mm, normal count is >10); anti-mullerian hormone (AMH) (<1ng/ mL is considered low); clomiphene citrate challenge (FSH >10 following treatment with clomiphene); age >35 years; family history of early menopause; single ovary or history of ovarian surgery, chemotherapy, or pelvic radiation (Practice Committee 2012).

Clinical Evidence Collectively, the 14 reviewed studies reported the following outcomes in women described as having DOR or as poor responders to IVF: • Higher clinical pregnancy rates between 22.1- 28.4% with DHEA supplemented cycles (Barad 2007, Gleicher 2012, Gleicher 2010A, Sonmezer 2009, Weghofer 2012). Three of these trials were uncontrolled; in the one casecontrol study, the control group had a clinical pregnancy rate of 11.9%, versus 28.4% in the DHEA group, HR pregnancy 3.8 (95% CI 1.2-11.8, p<0.05) (Barad 2007). In the second study, the DHEA supplemented cycle resulted in pregnancy rates of 44.4% versus 0% after embryo transfer compared to the first unsupplemented cycle (p<0.01) (Sonmezer 2009).

• Higher live birth rate: 23.1% with DHEA compared to 4.0% (p=0.05) without DHEA (RCT evidence) (Wiser 2010).

• Lower miscarriage rate: 15.1% with DHEA, which was lower than the national average; odds of miscarriage was reduced by approximately half: OR 0.49 (0.250.94, p=0.04) (Gleicher 2009). The miscarriage rate was reduced at all ages but most especially so in women over 35 years of age.

• Improvements in the follicular microenvironment due to a better blood supply to the ovaries as measured

by FF HIF1 levels (Artini 2012).

• Greater numbers of mature oocytes retrieved from selected follicles following ovarian stimulation (Artini 2012); and increased number of follicles >15mm (p=0.004), 17mm (p<0.05) and 10mm respectively (Hyman 2013, Sonmezer 2009, Yeung2012 RCT evidence).

• No significant change in AMH or FSH levels, but significantly increased antral follicle count and ovarian volume at wk 12 and 20 (RCT evidence, Yeung 2012; and Hyman 2013).

• Reduction in the number of aneuploidy embryos (p<0.029) (Gleicher 2010B) and increased embryo quality (p=0.04) (RCT evidence) (Wiser 2010).

• Increased good quality embryos at day two and three (p<0.05) (Barad 2006, Sonmezer 2009).

• Decrease in mean day three estradiol (p<0.01) (Sonmezer 2009).

• Reduction in cycle cancellation rates, 5.3% versus 42.1%, p<0.01 (Hyman 2013, Sonmezer 2009).

Of note, Gleicher et al investigated the effect of DHEA conversion to testosterone as a prognostic marker of the response to DHEA (2012). Androgen conversion was compared between conception and non-conception cycles. They found that the beneficial effect of DHEA on pregnancy rates was statistically associated with the efficiency of androgen conversion from DHEA, and the amplitude of testosterone gain; both younger women and certain FMR1 genotypes were found to convert more efficiently (Gleicher 2012).

In an excellent review, Gleicher and Barad briefly discuss other fertility related applications, for example the use of DHEA for idiopathic infertility and premature ovarian failure (POF) as distinct from DOR; however there is a lack of clinical evidence regarding these applications and the focus of published papers to date is on DOR (2011). Anecdotally, however, Gleicher et al report a handful of cases of POF at their and colleagues’ fertility centers that achieved pregnancy following several months use of DHEA, and are currently investigating this

more rigorously through a clinical trial(ClinicalTrials.gov ID#NCT00948857) (Gleicher2011, Mamas 2009).

Criticism Some have been critical of the use of DHEA in clinical practice for the treatment of DOR. In a commentary article, Urman et al argue that the evidence in support of DHEA is not of sufficient quality to merit use in practice (2012). At the time of publication there was only retrospective or uncontrolled studies and one RCT in existence (Wiser 2010), the latter of which Urman critiques as underpowered to detect the effects on pregnancy and other endpoints that were reported (2012). Although one additional placebo controlled RCT has since reported similar benefit of DHEA on DOR (Yeung 2012), there is admittedly still a need for further RCT level evidence. In addition, Urman is of the opinion that DOR with low AMH and few antral follicles will not be amenable to pharmacological therapy of any sort: “It is unlikely that any medication will be of benefit in a woman harboring ovaries devoid of antral follicles.

After all, one cannot stimulate what is not there” (Urman 2012). This statement does not however sufficiently explain the observations reported in several studies of DHEA that have been published, the majority of which have documented some level of improvement in markers of ovarian function associated with use of DHEA. A recent study exploring the mechanism of DHEA in DOR suggested that rather than somehow increasing the set number of follicles a woman possesses, DHEA may instead increase the quality of the few existing, antral follicles (Hyman 2013). This study found that although DHEA had no impact on baseline AMH or inhibin B levels, which are secreted by early to mid stage follicles, the antral follicle count nonetheless improved.

Authors concluded that “DHEA does not appear to exert influence via recruitment of pre-antral or very small antral follicles (no change in AMH and inhibin B), but rather by rescue from atresia of small antral follicles (increased AFC)” (Hyman 2013). There is clearly a need for further research to confirm the effect and mechanism of DHEA, however in the meantime a basis to utilize this promising therapy does appear to exist, particularly in women whose existing therapeutic options are limited.

Dosing The dosage generally used by studies reviewed here is 25mg three times per day. This is beyond that considered to be physiologic replacement dosages, typically considered to be 20-50mg/d for men and 10-30mg/d for women; however Olech points out that “higher dosages February/March 2013 l www.ihpmagazine.com 59

Fritz2.indd 59

13-02-01 4:00 PM

may be necessary for increasing suppressed DHEA and DHEAS levels secondary to chronic disease, adrenal exhaustion, and corticosteroid therapy” (2005). Indeed, higher dosages have been used in lupus, as will be reviewed in part II of this series.

Adverse Effects No serious side effects were reported by the studies included in this review. Gleicher et al report having treated over 1000 women with DOR with DHEA 25mg three times daily and observing no serious side effects other than acne, hair loss, or oily skin (2011).

Conclusion DHEA is a weak adrenal androgen that appears to positively influence early follicular development in women with diminished ovarian reserve (DOR). Two RCTs and 13 non-randomized studies in women with DOR show a promising role for DHEA in improving ovarian function and fertility. These studies suggest that DHEA can be dosed at 25mg three times daily for a minimum of six weeks up to three to four months for DOR. DHEA is a relatively safe agent with few side effects that may include acne, hair loss and oily skin. ■

The aging population in developed countries is experiencing an increase in the prevalence of neurodegenerative disorders that are placing a high burden on healthcare systems. The combined problems of lack of sustainable therapies and the absence of validated biomarkers for early diagnosis and intervention make these debilitating disorders a high priority for research. However, before biomarkers and therapies can be developed, scientists need to establish a clearer and more complete understanding of the molecular mechanisms behind neurodegeneration. Recently, researchers have linked the pathogenesis of many neurodegenerative disorders such as Parkinson’s (PD) and Alzheimer’s disease (AD) to abnormal protein folding, oxidative stress, and mitochondrial dysfunction. A specific class of proteins, called molecular chaperones (also known as heat-shock proteins), have emerged as potential targets for neuroprotection because of their ability to modulate abnormal protein folding and aggregation in disease states. We have discovered in our laboratory a novel molecular chaperone protein called Catecholamineregulated protein 40 (CRP40; 40kDa) that is expressed solely in the central nervous system (CNS) and blood. Our preliminary findings indicate CRP40 is an alternative splice variant of a larger, ubiquitously-expressed protein called mortalin, which has been linked to protein homeostasis, pathophysiology of neurodegenerative disorders, and has been shown to protect neurons from oxidative stress. Studies on CRP40 have revealed the presence of a conserved heat-shock motif, upregulated expression under cell stress, as well as its ability to decrease aggregation of proteins, suggesting heat-shock like functions of this novel protein. Interestingly, evidence has revealed that CRP40 may play a role in neurodegenerative disorders characterized by impairments of the dopamine (DA) system, such as Schizophrenia (SCZ) and PD, through its ability to bind DA and colocalize with components of the DA-synthesis pathway. Our group has also discovered that CRP40 expression is dysregulated in human post-mortem SCZ and Parkinson’s brain samples – a compelling finding that requires further study. In this review, we present evidence that CRP40 may play a role in CNS disorders, particularly disorders related to abnormal protein folding and impairments of the dopaminergic system. Further study of CRP40 and its mechanisms may aid in increasing the understanding of molecular chaperone function in neurodegenerative disorders, which is essential for accelerating future developments of biomarkers and sustainable therapeutics.

Neurodegenerative disorders: How molecular chaperones play a role Neurodegenerative diseases are increasing in prevalence in many developing countries and this trend is set to continue due to the rapidly aging population.

They encompass a heterogeneous group of disorders that can be described by progressive and selective loss of neuronal systems that are anatomically or physiologically related. Despite research advances over the past several decades, critical challenges still remain in understanding the pathology and underlying mechanisms behind these debilitating disorders. Converging lines of evidence have suggested a common â&#x20AC;&#x153;protein-conformationalâ&#x20AC;? pathogenic pathway for AD, PD, familial amyotrophic lateral sclerosis (FALS), Huntingtonâ&#x20AC;&#x2122;s disease (HD) and related polyglutamine (polyQ) expansion diseases.

Collectively, these disorders are characterized by the abnormal accumulation of insoluble neuronal or extracellular protein aggregates in the CNS (Hartl 2011, Muchowski 2005). However, the significance of these phenomena to the process of neurodegeneration is incompletely understood. Several groups have proposed that the formation of protein aggregates may be neuroprotective (Caughey 2003, Sisodia 1998).

However, any perturbation of protein homeostasis can impair the ability of proteins to function properly and perform their diverse biological roles that are essential for life.

There is still some debate about whether the aggregates formed by disease proteins are toxic.

Evidence has suggested that misfolded proteins can induce excitotoxicity or apoptosis via activation of caspase 3, and also affect neuronal synaptic function and axonal transport (Forman 2004). As well, toxic species in neurodegenerative disorders have been linked to various inflammatory responses, including increased oxidative stress, and mitochondrial dysfunction (Lin 2006). Indeed, there seems to be a common link between misfolded proteins and the resulting aberrations that occur in neurodegenerative disorders.

Protein quality or proteostasis is regulated by an

integrated network of proteins known as molecular chaperones. Molecular chaperones perform diverse roles in the cell including assisting with de novo protein folding, refolding of denatured proteins, protein trafficking, and degradation (Hartl 2011, Soti 2005).

Numerous classes of molecular chaperones have been described thus far. Many of these proteins are also known as heat-shock proteins (Hsp) or stress proteins because it has been found that various cellular stresses upregulate their expression. These may include heat-shock, glucose deprivation, exposure to heavy metals, protein kinase C (PKC) stimulators, amino acid analogues, calcium increasing agents, ischemia, microbial infections and various hormones (Ellis 2006).

Different families of molecular chaperone proteins are classified according to their molecular weights and include the Hsp40, Hsp60, Hsp70, Hsp90, Hsp100, and small Hsp proteins (Ellis 2006). Heat-shock proteins are expressed in the cytosol, nucleus, mitochondria, and endoplasmic reticulum, and typically have long half-lives of about 48 hours (Ellis 2006). Although the function of these proteins is broad, the Hsp70s, Hsp90s, and the chaperonins (Hsp60s) are specifically involved in de novo protein folding and refolding.

These classes of proteins are characterized as multicomponent molecular machines that have the ability to recognize exposed hydrophobic amino-acid side chains of misfolded proteins and guide proper folding through adenosine triphosphate (ATP)- and cofactor- mediated mechanisms (Hartl 2011). Due to their various roles, molecular chaperones are currently being investigated in a variety of disorders.

Indeed, molecular chaperone proteins are emerging as important players in a number of neurodegenerative diseases characterized by aberrations in protein conformation. The purported roles of molecular chaperones in neurodegeneration may include the following: 1) control of potentially toxic structural changes in disease-related polypeptides; 2) regulation of aggregation of proteins by directing towards formation of less toxic species; 3) control of degradation of toxic

agents and preservation of cellular degradation systems; 4) involvement in cell signalling and apoptotic events stimulated by abnormal protein aggregates, along with preservation of survival pathways; and 5) protection of mitochondria and neurons against oxidative stress evidenced in neurodegenerative disorders (Muchowski 2005). Further understanding of cellular chaperone networks will help to define their roles in neurodegenerative diseases where protein homeostasis has been impaired, and elucidate ways in which they may be manipulated to serve as possible therapeutic factors in these debilitating disorders.

Mortalin: an essential mitochondrial heat-shock protein The heat-shock protein 70 (Hsp70; 70kDa) family represents one of the most ubiquitous classes of molecular chaperones. Mortalin, also known as the mitochondrial heat-shock protein (also referred to as mtHsp70 or Grp75), is an essential ubiquitously expressed molecular chaperone with multiple roles in mitochondrial biogenesis, maintenance of mitochondrial protein integrity, and regulation of import of mitochondrial proteins into the matrix (Deocaris 2008).

Recently, mortalin has been implicated in neurogenesis and neurodegeneration processes and linked to AD, PD, as well as HD (Deocaris 2008). Also, since mortalin has been found to exert various cytoprotective functions that permit cell survival under stressful conditions, it has been implicated in cancer and aging systems (Kaul 2007).

Evidence for the involvement of mortalin in several human diseases has been accumulating over the past decade. Gabriele and colleagues (2010) studied the possible involvement of mortalin in the pathogenesis of SCZ and have shown that antisense knockdown of mortalin in the medial prefrontal cortex resulted in impairments of DA-mediated behaviours including prepulse inhibition and social interaction deficits (Gabriele 2010). Mortalin has also been implicated in AD through several studies. Osorio and colleagues (2007) showed differential expression of mortalin isoforms in hippocampi of AD patients. In another study using an animal model of AD, the ApoE knockout mouse model, it was shown that mortalin sustained ADassociated oxidative damage, suggesting the involvement of this protein in the pathogenesis of AD (Choi 2004).

Mortalin has also been linked to neurodegeneration in PD based on interactions with PD-associated proteins,

including the redox-sensing DJ-1 protein that maintains mitochondrial function (Kaul 2007).

Mortalin is expressed from chromosome 5q31.1 (Kaul 1995). A recent study found that PD patients display mutations in the mortalin gene that have been associated with impaired mitochondrial function that is critical in protection from neurodegeneration (Burbulla 2010). Two of these mutations were located in the carboxyl-terminal substrate-binding domain of mortalin, indicating that this functional region of mortalin further characterization.

The combined evidence from literature underscores the critical role of mortalin as an important mitochondrial stress protein in a variety of neurodegenerative disorders that needs to be investigated in more detail.

Interestingly, several studies have suggested that mortalin may play a role in brain ischemia, as it is upregulated following brain injury (Deocaris 2008).

This protein may serve a protective function in ischemia by limiting the accumulation of reactive oxygen species in neurons (Liu 2005). Further, in vivo overexpression of mortalin in rat brain neurons and astrocytes following induction of ischemia significantly reduced infarct volume, improved neurological function and provided protection from oxidative damage in animals (Xu 2009).

Mortalin has been found to interact with the apoptosis-inducing factor (AIF) (Sun 2006). Normally, when AIF is released from the mitochondria, it may be translocated to the nucleus where it can cause caspase-independent apoptosis. It has been suggested that mortalin sequesters AIF and thus suppresses cell death (Sun 2006). Interestingly, this protective ability of mortalin was not retained in Hsp70 deletion mutants lacking the carboxyl-terminal (Ravagnan 2001). The functionality of the mortalin carboxyl-terminal was further confirmed in studies by Sun and colleagues (2006) who found that Hsp70 mutants lacking the entire amino-terminal domain and Hsp70 ATPasedeficient point mutants retained the ability to protect primary astrocytes against ischemic insults in vitro as well as to inhibit AIF translocation to the nucleus.

This indicated that the carboxyl-terminal was indeed sufficient for protection against ischemic brain injury (Sun 2006).

Indeed, the carboxyl-terminal of mortalin seems to serve a specific function in neurodegenerative disorders and oxidative stress. McMaster University researchers have recently discovered a novel protein that is

related to the carboxyl-terminal of mortalin, and this protein is under investigation for its possible roles in neurodegeneration.

Catecholamine-regulated protein 40 (CRP40): A novel molecular chaperone The Catecholamine-Regulated Protein 40 is a novel heat-shock like protein that was discovered and characterized by Drs. Mishra and Gabriele of McMaster University (Hamilton, Canada) (Gabriele 2009, Nair 2001). CRP40 is a splice variant of mortalin, showing significant homology to mortalinâ&#x20AC;&#x2122;s carboxyl-terminus.

Specifically, the sequence between exons 10-17 is identical to mortalin, with a promoter region at intron 9 (Gabriele 2009). Interestingly, this carboxyl-terminus homology means that the above discussed PD-related mortalin mutations would affect CRP40 function as well.

Like mortalin, CRP40 belongs to the Hsp70 family, as evidenced by the following characteristics: 1) CRP40 exhibits the characteristic and conserved heat-shock motif; 2) expression of CRP40 is inducible by elevated temperature; and 3) the organellar localization motif, which allows Hsp70s to translocate between organelles, is conserved (Gabriele 2009, Nair 2001). Although the full mechanistic functions of CRP40 have not yet been elucidated, evidence suggests that it may play a role as a molecular chaperone, not unlike mortalin. Further study is required to determine how CRP40 functions in protein folding and proteostasis as related to neurodegenerative conditions.

One major distinction between CRP40 and mortalin lies in their localization. While mortalin is expressed in all cells, CRP40 is found exclusively in the CNS and in specific blood cells (Ross 1995). This pattern of expression makes CRP40 of particular interest to research in neurological disorders, especially neurodegeneration, as CRP40 may serve a more specific function in CNS disorders.

CRP40 may have similar roles to mortalin as a chaperone protein, but CRP40 also displays some functions in neuroprotection. Thus far, studies have shown that upregulation of CRP40 in the presence of excess DA can actually be inhibited by treatment of cells with antioxidants, suggesting that CRP40 is a reactant protein to the oxidative stress caused by the natural oxidation of DA (Nair 2001). Further, heat-shocked cells that were subsequently treated with CRP40 protein showed decreased denaturation and aggregation of

proteins in comparison to untreated cells â&#x20AC;&#x201D; a finding that highlights CRP40 as a heat-shock protein and molecular chaperone (Gabriele 2009, Nair 2001).

Unlike other members of the Hsp70 family, CRP40 contains the tyrosine and aspartate residues necessary for DA binding (Gabriele 2009, Nair 2001). Staining studies show that CRP40 colocalizes in neuronal cells with DA and Tyrosine Hydroxylase (TH), the ratelimiting molecule in DA synthesis (Gabriele 2009, Goto 2001, Nair 2001). This protein actually displays covalent interactions with the catecholamine neurotransmitters, but does not interrelate with serotonin or other amines (Nair 2001, Ross 1993, Ross 1995). In fact, CRP40 expression is inducible by presence of excess DA, which makes it an interesting target for research related to the neurodegenerative disorders with dopaminergic components, like SCZ and PD (Nair 2001).

Recent reports have revealed the importance of CRP40 to these dopaminergic degenerative conditions.

Gabriele et al. (2005) conducted a study using human post-mortem SCZ samples obtained from the Stanley Foundation Neuropathology Consortium. Results showed that CRP40 is dysregulated in the affected brain regions and suggest its involvement in the pathogenesis of SCZ. In fact, there was a significant decrease in the protein expression of CRP40 in patients with SCZ (Gabriele 2005). Similarly, in studies using human postmortem PD brain samples, Mortalin/CRP40 were found to be dysregulated in PD-specific brain regions (Jin 2006, Shi 2008). Specifically, there is a quantitative decrease in Mortalin/CRP40 expression with progression of the disease (Shi 2008). These reports present important evidence that CRP40 may act as a potential biomarker for neurological disorders. Future studies will be conducted to determine whether CRP40 and its dysregulation in neurological disorders may be exploited for early disease-detection and monitoring of disease progression.

Since the discovery of CRP40, new findings and evidence have converged to reveal its involvement in neurodegenerative disease pathology.

Specifically, CRP40 seems to have great significance to CNS disorders involving DA. As well, CRP40 may be involved in the crucial process of proteostasis that is impaired in neurodegenerative diseases. The Gabriele group is moving forward with this important research and has engaged in studies of both basic and clinical sciences in order to elucidate potential breakthroughs of CRP40 in the realm of neurodegenerative disorders. â&#x2013;

METAGENICS PHYTOMULTI PhytoMulti by Metagenics is a robust multivitamin fortified with over 20 phytonutrient extracts, including lutein, greet tea extract, and resveratrol. As such, PhytoMulti is an ideal product for use in adults in order to optimize vitamin and mineral status, in lieu of poor dietary intake or increased physiological requirements, but also provides a broad spectrum of plant nutrients in order to mimic the many health effects of a plant-based diet. The USDA MyPlate recommendations include between 9-10 servings of fruits and vegetables per day, but less than 10% of adults achieve this target (Murphy 2011).

The Mediterranean dietary pattern is an example of a well-researched diet that is very high in phytonutrients. The Mediterranean diet is associated with markedly lower risk of several chronic diseases, including cardiovascular disease and diabetes (Eustruch 2006, Interact Consortium 2011, Nordmann 2011), and a high fruit and vegetable diet has been shown to reduce risk of cancer (Block 1992), in large part due to high amounts of combined phytonutrients. Phytonutrients have been shown to confer beneficial health effects through numerous mechanisms, including modulation of signal transduction pathways, antioxidant properties, and through hormonal effects. PhytoMulti contains over 20 of these plant substances, including: lutein, zeaxanthin, acacia nilotica, and extracts of artichoke leaf, grape seed extract, green coffee, green tea, citrus bioflavonoids, resveratrol, prune skin, watercress, rosemary, pomegranate, lycopene, cinnamon, bitter melon, and blueberry.

Multivitamin supplementation has been shown to benefit a variety of physical and cognitive parameters particularly in children, pregnant women or women who may become pregnant, individuals under increased stress, individuals with poor absorption, and the elderly. In pregnancy, supplementation with a folic acid containing multivitamin has been shown to reduce risk of complications such as placental abruption, preeclampsia, in addition to decreasing risk of congenital defects including neural tube defects, anencephaly, myelomeningocele, meningocele, oral facial cleft, structural heart defects, limb defects, urinary tract anomaly, and hydrocephalus when used prior to conception and during the first trimester (Wilson 2007).

Periconceptional multivitamin use in lean women has been shown to decrease the risk of small-for-gestational-age (SGA) under the 5th percentile by up to 46% compared to non-users (OR=0.54, 95% CI), and has been associated with a 71% reduction in preeclampsia risk (OR=0.29, 95% CI) in lean women, users versus non-users (Catov 2007; Bodnar 2006). Periconceptional multivitamin use has also been associated with reduced risk of several pediatric cancers, including leukemia (OR=0.61) (39% reduced risk); pediatric brain tumors (OR=0.73) (27% reduced risk); and neuroblastoma (OR=0.53) (47% reduced risk) in a recent metaanalysis (Goh 2007).

In patients under high levels of psychological stress, use of a multivitamin has been shown improve perceived levels of stress and psychometric parameters.

Gruenwald et al (2002) found that use of a multivitamin for 6 months resulted in a 40.7% overall improvement in self rated stress levels using a psychologicalneurological questionnaire to assess “psycho-organic, central vegetative, and somatic discomforts.” Other outcomes included a 29% decrease in frequency of infections and 91% decrease in gastrointestinal discomfort. Schlebusch et al (2000) found similar benefit on various psychometric parameters in a 30 day trial (1997), and Harris found that multivitamin supplementation can improve measures of mood, stress, and alertness in older men (2011). Importantly, supplementation with a spectrum of B vitamins has also been shown to reduce ratings of workplace stress (Stough 2011).

Several trials have shown increased cognitive performance in children taking a multivitamin supplement. Benton et al (1988) found a significant increase in nonverbal intelligence in children taking a multi versus those taking placebo after 8 months’ intervention. In a 14 month study of 608 children, Vazir et al (2006) found a significant increase in attention-concentration increment scores in those supplemented with a micronutrient-fortified beverage versus those receiving placebo.

Additional benefits demonstrated in children include a reduced mean duration (5.0 versus 7.5 days, supplement versus placebo) of several common childhood illnesses including such as fever, cough and cold, diarrhea, and ear infections (Sarma 2006).

In the elderly, multivitamin supplementation has been shown to significantly improve status of such nutrients as vitamin D, vitamin B6, vitamin B12, folate, vitamin C, vitamin E, zinc, and selenium (McKay 2000; Girodon 1997). In addition, supplementation has also been found to significantly reduce rates of infection in the elderly, as found a trial in 81 subjects given various supplemental combinations of micronutrients and followed over a 2 year period (Girodon 1997).

N-acetyl-cysteine A Versatile Intervention Colin MacLeod, ND Kinesis Health Associates 164-166 Ochterloney St. Dartmouth, Nova Scotia, Canada

NAC at high oral or intravenous doses is the gold standard treatment for acetaminophen toxicity. NAC antidotes acetaminophen poisoning by repleting glutathione stores and as a result mitigates liver damage. NAC exerts its therapeutic action through glutathione repletion, as well as glutamate modulation and mucous thinning in treating other health conditions. Recently data has surfaced supporting NAC as an effective treatment for a variety of health conditions, including non-acetaminophen-induced acute liver failure, COPD, flu prevention, idiopathic pulmonary fibrosis, acute renal failure due to contrast media, schizophrenia, bipolar disorder, autism, grooming disorders, obsessive compulsive disorder, addiction and angina. Adverse effects of NAC by the oral route are mild at low doses and exclusively gastrointestinal, while IV NAC can lead to anaphylactic reactions, including pruritus, rash, tachycardia, hypotension, bronchospasm and syncope. Care should be taken with concomitant treatment with nitrates and NAC, due to NACâ&#x20AC;&#x2122;s potentiating effect on nitrates. It is evident from the published data that NAC is a safe and valuable clinical tool, useful for treating a wide variety of health conditions.

Introduction Although widely accepted as the primary antidote to acetaminophen overdose and as a mucolytic agent, N-acetyl-cysteine (NAC) has a variety of clinical applications, some of which have only recently come to light. Cysteine is a non-essential amino acid that is found mostly in animal products. NAC is essentially cysteine with an acetyl group attached. This acetyl group limits digestive degradation and promotes absorption. NAC powder has a white colour and dissolves clear to slightly purple in water. NAC has a sulphur-like odour and unpleasant taste which makes high oral doses challenging to administer.

Standard Dosing NAC is commonly available without prescription in 500mg or 600mg capsules. NAC is also available at 200mg/ml solution for oral and intravenous use in the treatment of acetaminophen overdose and as a mucolytic in pulmonary conditions with excessive mucous. Dosing of NAC is condition specific

and has been best established in the treatment of acetaminophen toxicity.

In the treatment of acetaminophen toxicity in adults, the oral dose of NAC is 1,330 mg/kg (93,100 mg in 70 kg individual) in 18 doses spread over three days: a loading dose of 140 mg/kg followed by 17 doses of 70 mg/kg every four hours (Prescott 2005). The intravenous dose is 300 mg/kg (21,000 mg in 70 kg individual) divided into three separate IV bag drips over 21 hours: a loading dose of 150 mg/kg in 5% dextrose is given over a 15-minute period, followed by 50 mg/kg in four hours and 100 mg/kg in 16 hours, for a total dose of 300 mg/kg in 20 and one quarter hours (Prescott 2005).

The intravenous route is used in Canada, Europe and Australia, whereas the oral route is used in the United States.

Liver damage is prevented most effectively when treatment is administered orally (Smilkstein 1988) or intravenously (Whyte 2007) within eight hours of the acetaminophen overdose. However, treatment should not be denied up to 24 hours after poisoning as there February/March 2013 l www.ihpmagazine.com 73

is still life-saving potential (Prescott 2005). Most conditions experimentally treated with NAC have used considerably smaller doses than that used for acetaminophen toxicity. Limited data exists on the efficacy and safety of nebulized NAC. Pharmacokinetics When 600mg of NAC was administered orally to healthy human volunteers, 6.4-10% was absorbed into the bloodstream intact (Borgström 1986). In an animal model, it has been found that low oral bio-availability is due, in part, to de-acetylation and conversion to other sulphur-containing compounds within the digestive tract, but that a significant amount of NAC reaches the blood as other-sulphur containing compounds (Cotgreave 1987).

The half-life of NAC in healthy adults has been reported differently by different investigators, including 2.27 hours (Borgström 1986) and 5.7 hours (Prescott 1989) for the intravenous route, and 3.7 hours for the oral route (Nolin 2010). The newborn half-life of NAC has been reported to be between 7.8 and 15.2 hours when administered intravenously, but depends largely on weight and gestational age (Ahola 1999). The half-life of NAC is significantly longer when given orally to patients with end-stage renal disease (Nolin 2010), or chronic liver disease (Jones 1997).

Pregnant women with acetaminophen poisoning should be treated with a standard high-dose oral NAC protocol due to its life-saving potential for the mother and fetus (Riggs 1989). If NAC is given to a pregnant woman in high oral or intravenous doses placental transfer will occur (Horowitz 1997).

Minimal data exists on the safety and efficacy of IV NAC in pregnant women for treatment of acetaminophen toxicity.

Mechanism of Action NAC is believed to act through three major mechanisms: providing glutamate for neurotransmission, providing cysteine for the synthesis of glutathione, and cleaving disulphide bonds present in mucous.

Glutathione, the most ubiquitous endogenous antioxidant is composed of three major amino acids: glutamate, glycine and cysteine. Of its three components, cysteine supply is the rate limiting step in glutathione production (Lu 2012, Radtke 2012). Some of the therapeutic effects of NAC have been attributed to its ability to provide glutathione, including in pulmonary conditions

and hepatic injury. NAC does not seem to increase plasma glutathione in healthy human controls but will increase plasma glutathione in humans who have depressed glutathione stores from oral acetaminophen dosing (Burgunder 1989).

The activity of NAC in psychiatric conditions has been postulated to be due to its ability to provide glutamate for neurotransmission and in restoring brain glutathione. Altered glutamate status has been reported to be an important factor in psychiatric conditions with an addictive or compulsive component (Dean 2011). NAC’s structure also includes a free sulphhydryl (-SH) group which is thought to act on the relatively weak disulphide bonds within mucous to break it into smaller, less viscous segments which can be more easily cleared.

Clinical Indications Acetaminophen Toxicity NAC has been used for over 30 years as an antidote to acetaminophen toxicity (Scalley 1978). NAC’s remarkable efficacy as an acetaminophen antidote can be seen in observational evidence where a delay of NAC administration of even a few hours can be the difference between full recovery and liver failure (Smilkstein 1988). NAC’s ability to replete glutathione is the mechanism by which it antidotes acetaminophen toxicity.

Non-Acetaminophen-Induced Acute Hepatic Failure NAC has proven to be helpful in increasing survival in hepatitis- and drug-induced liver failure at high oral (Mumtaz 2009, Sotelo 2009) and intravenous (Kortsalioudaki 2008, Lee 2009) doses similar to those used in acetaminophen toxicity. Kortsalioudaki found that intravenous NAC administered to children with non-acetominophen acute liver failure resulted in shorter length of hospital stay, higher incidence of native liver recovery without transplantation, and better survival after transplantation (2008). Much smaller oral doses of 600mg/day have been associated with no change in duration of hospitalization compared to controls (Gunduz 2003).

High-dose NAC is a promising treatment in drug- or hepatitis-induced acute hepatic failure.

Although no firm dosing schedule can be identified, an oral or intravenous protocol similar to that used in acetaminophen toxicity should be considered due to the increased survival evidenced in four human trials (Mumtaz 2009, Sotelo 2009, Kortsalioudaki 2008, Gunduz 2003).

Chronic Obstructive Pulmonary Disease Several studies have been performed on the effectiveness of NAC for Chronic Obstructive Pulmonary Disease (COPD) using oral doses of 6001200mg/day. Some studies (Hansen 1994, Pela 1999, Stav 2009, Völkl 1992, Zuin 2005) though not all (Black 2004, Decramer 2005, Lukas 2005, Schermer 2009) found that use of NAC in addition to conventional treatments is more effective in the management of COPD related symptoms compared to conventional treatment alone. In addition, several trials report improvements in specific measurements of lung function, including FEV1, inspiratory capacity (IC), and functional residual capacity (FRC) (Decramer 2005, Pela 1999, Stav 2009).

It should be noted that although many of the trials utilize FEV1 as the primary measure of effectiveness, failure to show benefit on this outcome should not be strictly interpreted as a failure of treatment success. Stav et al point out that although FEV1 is used to classify disease severity and is a good predictor of COPD mortality, it is a “poor predictor of clinical symptoms, exercise tolerance, and response to bronchodilators in COPD” (2009). Furthermore, COPD is characterized by “disease changes at the level of small airways, which is not usually expressed by the measurement of FEV1… IC [inspiratory capacity], however, is a lung volume measure that has been found to correlate well with patient dyspnea and exercise tolerance (2009). For instance, reduced IC during exercise correlated well with dynamic hyperinflation (Stav 2009). Some trials have shown small but significant improvements in FEV1 associated with NAC treatment (Pela 1999, Völkl 1992, Zuin 2005), while others have not (Decramer 2005).

The BRONCUS trial was a large (N=523), high quality trial showing no effect of 600mg NAC compared with placebo on the maximal forced expiratory volume in one second (FEV1) and prevention of COPD exacerbations (primary outcomes) when given over a three year period (Decramer 2005). However, a significant reduction in the functional residual capacity (FRC), the volume remaining in the lungs at the end of passive expiration, was seen in the NAC group on secondary analysis: FRC decreased from 4·46L to 4·09L in patients assigned to NAC, p<0.0001 (Decramer 2005). Other trials have also noted improvements in other measures of lung function associated with air trapping, including IC and FVC (Stav 2009). Considering its negligible adverse effects, low cost, and data showing benefit on measures of lung function associated with air trapping, NAC deserves to be considered as an adjunctive treatment option in COPD at oral doses of 600-1200mg/day.

Flu Prevention One large (N=262), high-quality trial has been performed on the effect of NAC on influenza. Elderly patients were treated prophylactically for six months during flu season with oral NAC at 600mg twice daily or placebo. Although influenza infection rates were not different between treatment and placebo groups, influenza-like episodes, symptom severity and length of time confined to bed in the NAC group were significantly lower. The NAC group was also found to have a significant immune stimulation as compared to baseline and compared to the placebo group, as measured through anergy (De Flora 1997).

Idiopathic Pulmonary Fibrosis Idiopathic Pulmonary Fibrosis (IPF) is a condition of unknown etiology which is characterized by scarring of the lungs and most commonly affects people 50-70 years of age. One randomized, double-blind placebocontrolled trial (N=182) administered NAC orally at 600mg three times daily as an add-on to standard treatment in patients with IPF. The NAC group had significantly slowed deterioration of lung vital capacity (VC) and diffusion capacity compared to the placebo group (Demedts 2005). Conversely, data on nebulized NAC suggests that it does not improve outcomes in IPF (Bando 2010, Tomioka 2005) and may even lead to acute exacerbations (Bando 2010). On considering these trials, oral NAC at 600mg three times daily should be considered as an add-on to standard medical treatment for IPF. Renal Protection from X-ray Contrast Media Contrast media used during radiographic examination can cause nephropathy and acute renal failure. Risk factors for contrast-induced nephropathy include compromised kidney function, diabetes and reduced intravascular volume. Numerous clinical trials have been conducted over the past decade on prevention of acute renal failure with most using oral doses of 600mg NAC twice daily on the day before and the day of contrast media administration. As a whole the results have been mixed with some studies showing benefit from NAC (Briguori 2011, Koc 2012, Sar 2010) and others showing no effect (Anderson 2011, Gurm 2012, Jaffery 2012).

As is the case with COPD, the evidence is equivocal, but the intervention has negligible adverse effects and the cost is low. With this in mind, oral NAC at 600mg twice daily on the day before and the day of contrast media administration should be considered for patients with compromised kidney function as an add-on to standard treatment for prevention of acute kidney failure.

Nitrate-treated Angina Sulfhydryls seem to be fundamental to nitrateinduced vasodilation (Mehra 1994). Data also suggests that in angina patients receiving nitrates, NAC given orally may lead to a significant decrease in ischemic effects as assessed by ECG (Boesgaard 1991), myocardial infarction rates (Ardissino 1997), angina symptoms and death rates (Ardissino 1997).

Oral dosages in this setting have ranged from 18002400 mg per day in divided doses (Ardissino 1997, Boesgaard 1991). NAC given intravenously may lead to a decreased tolerance to nitrates (Boesgaard 1992, Pizzulli 1997) and a decreased rate of myocardial infarction (Horowitz 1988) in nitratetreated angina patients. However, not all trials have shown that NAC is of benefit, when given orally (Hogan 1990) or intravenously (Parker 1987).

Considerable care must be taken when giving NAC to nitrate-treated patients orally (Ardissino 1997) or intravenously (Horowitz 1988) due to NACs ability to potentiate associated hypotension and headaches. If prescribed, oral NAC should be started at a low dose (600mg three (Ardissino 1997) or four times daily (Boesgaard 1991)) with careful monitoring of blood pressure and headache occurrence. No clear recommendation can be given for intravenous dosing.

Schizophrenia Three trials have examined NAC in patients with schizophrenia (Berk 2008, Carmeli 2012, Lavoie 2008). One double-blind, placebo-controlled trial (N= 140) using oral NAC at 1,000mg twice daily showed statistically significant improvements in those treated with NAC across several standardized schizophrenia measurement scales, and akathisia (restless leg syndrome) also improved significantly compared to placebo (Berk 2008). The mechanism by which NAC treats schizophrenia is thought to be through brain glutamate/ NMDA receptor modulation and reduction of oxidative stress (Dean 2011).

Lavoie et al conducted a randomized, doubleblind, cross-over trial comparing 2g NAC to placebo for a period of 60 days to investigate N-methyl-D-aspartate (NMDA) receptor function, characteristically low in schizophrenia (2008).

Mismatch negativity (MMN) is an auditory evoked potential (AEP) component related to NMDA receptor function that is impaired in patients with schizophrenia (Lavoie 2008). In this study, treatment with NAC significantly improved MMN generation compared with placebo (p=0.025),

suggesting improved NMDA receptor activity, but the study was not continued for long enough to observe changes in clinical severity as reported by the same group in Berk 2008 (above) (Lavoie 2008).

Lastly, a recent proof-of-concept study found that NAC was able to significantly increase multivariate phase synchronization (MPS) on EEG testing compared to placebo over the left parieto-temporal, the right temporal, and the bilateral prefrontal regions in patients with schizophrenia (Carmeli 2012). Authors suggested that this may be an early marker of clinically important treatment effects.

Bipolar Disorder Two small double-blind, placebo-controlled trials (N=75, N=17) in patients diagnosed with bipolar disorder showed very encouraging improvement in measures of symptom severity, functioning and quality of life with oral NAC at 1,000mg twice daily as an add-on to conventional therapy (Berk 2008, Magalhães 2011A). Improvements were evident by eight weeks (Beck 2008). In a sub-analysis of the study

by Berk 2008, six of seven participants with bipolar II in the NAC group experienced a full remission of depressive and manic symptoms, compared to only two of seven in the placebo group (p=0.031) (Magalhaes 2011B). In an analysis of the effect of adjunctive NAC treatment on depressive symptoms in bipolar patients, Magalhaes et al reported “very large effect sizes in favor of NAC … for depressive symptoms and functional outcomes .... Eight of the ten participants on NAC had a treatment response at endpoint; the same was true for only one of the seven participants allocated to placebo” (2011A).

A report of a larger cohort (N=149) from the two-month open label phase following an RCT showed similar results, which were described by the authors as a “robust decrement in depression scores” associated with NAC treatment (Berk 2011). Adverse effects were non-significant in all three trials.

Autism A small (N=33), 12-week double-blind randomized placebo-controlled trial treated autistic patients (3.210.7 years of age) with oral NAC in an escalating dose schedule reaching a maximum of 900mg three times daily. Compared with the placebo group, the NAC group had significant improvements on the Aberrant Behaviour Checklist irritability subscale. Adverse effects were mild and exclusively gastrointestinal (Hardan 2012).

Grooming Disorders There are several case reports and small trials of oral NAC in the treatment of addiction, compulsive disorder and excessive grooming disorders. It has been suggested that the mechanism of action may involve changes to glutamate levels in the brain (Dean 2011).

One small (N=50) randomized, double-blind trial compared NAC 1,200mg or 2,400mg per day to placebo in the treatment of trichotillomania (compulsive hair pulling). Significant improvements were noticed after nine weeks of treatment in hair pulling with 56% of participants in a NAC treated group reporting “much or very much improved” whereas 16% in placebo group reported the same level of improvement (Grant 2009). Another two cases of trichotillomania showed encouraging improvement when treated with oral NAC at 1,200 mg/day for three and six months, respectively (Rodrigues-Barata 2012).

In the case of nail biting, three patients showedcomplete abstinence of nail-biting after oral NAC at 1,000mg bid for four to seven months (Berk 2009). Encouraging improvement was also seen in one case of trichotillomania, one case of nail biting with trichotillomania and one case of skin picking when treated with oral NAC at 1,800-2,400mg/day (Odlaug 2007).

Obsessive Compulsive Disorder A small (N=36) randomized, double-blind trial compared 600-2,400mg/day NAC and placebo orally for 12 weeks in patients with obsessive compulsive disorder who were refractory to SSRI treatment.

The patients in the NAC group had a 52.6% rate of “full response”, while the patients taking placebo had a 15% rate of “full response”. Full response was defined as a 35% or greater reduction on the YaleBrown Obsessive Compulsive Scale. The Yale-Brown Obsessive Compulsive Scale (Y-BOCS) score was also significantly improved in the NAC group as a whole (p<0.001) (Afshar 2012).

Addiction Two small (N=13) (N=15) placebo-controlled trials (LaRowe 2006, 2007) and one small (N=23) openlabel trial (Mardikian 2006) have shown significant reductions in cocaine craving and usage with oral doses of NAC at 1200-3600mg/day.

Another small (N=116), eight-week doubleblind randomized placebo-controlled trial targeted promoting cannabis abstinence in adolescents.

Participants were given 1200mg NAC twice daily or placebo orally, along with brief weekly counselling sessions and a small cash-based reward system. When

adjusted for cannabis use at baseline, the NAC group had significantly higher odds than the placebo group of negative urine cannabinoid tests during treatment, OR 2.4 (95% CI 1.1-5.2) (Gray 2012).

An open-label trial followed by a double blind placebo-controlled trial investigated the effect of oral NAC at 1,800mg/day on pathological gambling.

Significant improvements were seen in the Yale-Brown Obsessive Compulsive Scale Modified for Pathological Gambling in the NAC group compared to the placebo group in both sections of the study (Grant 2007).

Although individually these case studies and clinical trials modestly support NAC use, the totality of evidence supports oral NAC at 1,200-3,600mg/day as a viable treatment option in addiction (specifically cocaine, cannabis and gambling), excessive grooming behaviours (specifically trichotillomania, skin picking and nail biting) and obsessive compulsive disorder.

Adverse Effects and Toxicity A safety analysis of high-dose NAC examined its effects on 503 patients with acetaminophen toxicity.

The oral route caused nausea and vomiting in 23% of patients and anaphylactic reactions in 2%. The IV route caused anaphylactic reactions in 9% of patients and nausea and vomiting in 6% of patients. The anaphylactic reactions were, in decreasing order of occurrence, pruritus, tachycardia, flushing, urticaria, non-urticarial rash, hypotension, bronchospasm and syncope (Bebarta 2010).

One retrospective study of 187 patients with acetaminophen toxicity treated with intravenous NAC found only seven adverse reactions, six being cutaneous and one being life-threatening, but not clearly caused

by NAC (Kao 2003). Massive accidental intravenous overdoses have been reported to cause kidney failure (Mullins 2011), severe brain injury (Heard 2011) and death (Bailey 2004, Elms 2011).

Oral and intravenous NAC are considered to be of equal efficacy in treating acetaminophen poisoning (Kanter 2006). The intravenous route is not recommended for patients prone to anaphylaxis or at high risk for bronchospasm, such as asthmatics. The oral route is not recommended for patients with nausea or vomiting severe enough to render oral treatment ineffective (Kanter 2006). Oral doses of 600mg twice daily were associated with an insignificant adverse effect profile compared to placebo in a 262 person trial (De Flora 1997).

Conclusion NAC, the standard treatment for acetaminophen toxicity, has several relatively unknown clinical uses, including treatment of acute liver failure, COPD, flu prevention, idiopathic pulmonary fibrosis, acute renal failure due to

contrast media, schizophrenia, bipolar disorder, autism, grooming disorders, obsessive compulsive disorder, addiction and angina. Care should be taken to avoid adverse effects associated with nitrate potentiation in angina treatment. ■

PRODUCT MONOGRAPH Bio-Fen Bio-Fen Plus is an oral natural health product used in the treatment of hereditary androgenic alopecia (AGA) for male or female pattern baldness.

Without treatment, AGA is progressive, and causes social distress in many affected men and women (Sinclair 1998). Bio-Fen Plus contains extracts of fenugreek seeds, saw palmetto berries and flax lignans, as well as activfuel+ specific vitamins. Each ingredient is known to possess inhibitors of the enzyme 5 -reductase.

These inhibitors responsible for relieving symptoms associated with hereditary activfuel+ is a sports nutrition supplementare designed specifically for pre- and during- exercise consumption.

Bio-Q10 SAP PRODUCT MONOGRAPH

WHAT IS COENZYME Q10?

Coenzyme Q10 (CoQ10) is a quinone compound synthesized in the human body and has properties similar to those of vitamins.(1, 2) Coenzyme Q10 occurs widely in living organisms, and because of its ubiquitous distribution in nature it is also known as ubiquinone. Structurally, CoQ10 (C59H90O4) is a benzoquinone ring compound, has 10 isoprenoid units in the side chain, and occurs naturally in the trans configuration.

CoQ10 is present in all human tissues, highly concentrated in the mitochondria as an endogenous cofactor in the mitochondrial energy production.(2, 3) Another important function of CoQ10 is as an antioxidant.(1) Many chronic diseases are associated with dysfunctional energy metabolism, and CoQ10 supplementation has been widely tested and used in the treatment of cardiac, neurologic, oncologic, as well as other disorders.(3) Used in most countries, CoQ10 supplementation targets improving cellular bioenergies, counteracting oxidative stress and slowing down some aging-related pathologies.(2, 4)

with other medications with a health care provider.(3) There is not enough scientific evidence to support the safe use of CoQ10 during pregnancy or lactation.(3) Statins, which are potent inhibitors of cholesterol biosynthesis, also inhibit CoQ10 synthesis and thus lower its endogenous levels in the body.(8) Even brief exposure to statin therapy causes a marked decrease in blood CoQ10 concentration leading to exercise intolerance, myalgia (heart pain) and myoglobinuria. However, these conditions are reversed with CoQ10 supplementation.(8)

CARDIOVASCULAR INDICATIONS

Present in all human tissues, ~50% of CoQ10 is localized in the mitochondrial membrane.(5) CoQ10, a cofactor in the mitochondrial electron transport chain (ETC), is essential for ATP production and therefore plays a fundamental role in cellular bioenergies. CoQ10 mainly functions in the ETC as a mobile redox agent shuttling electrons and protons; however, the redox functions of CoQ10 exist outside of the mitochondria. CoQ10 in its reduced form, ubiquinol, is a powerful antioxidant. As an antioxidant, CoQ10 prevents lipid peroxidation (3) and can recycle and regenerate other antioxidants such as tocopherol and ascorbate.(5)

Numerous clinical trials supplementing with 100–300 mg/day of CoQ10 have found improvements in several clinical parameters related to chronic heart failure (CHF), including frequency of hospitalization, dyspnea, fatigue, and edema.(3, 4, 9) A clinical trial of 23 patients with CHF supplementing oral CoQ10 (100 mg t.i.d.) resulted in improved functional capacity, endothelial function, and left ventricular contractility without any side effects.(10) Similarly, CoQ10 supplementation may offer myocardial protection during cardiac surgery and improve postoperative cardiac function, as well as reduce myocardial structural damage.(11) A review of clinical trials using CoQ10 at various doses for hypertension, typically as adjuvant therapy, found a mean decrease in systolic and diastolic blood pressure of 16 and 10 mmHg, respectively.(12) Additionally, preliminary human studies of patients within three days after a heart attack given CoQ10 orally reported reductions in deaths, abnormal heart rhythms, and second heart attacks.(9) CoQ10 supplementation may also benefit cardiomyopathy (dilated, hypertrophic), angina from clogged heart arteries, and atherosclerosis.(9)

ABSORPTION AND TRANSPORT

NEUROLOGIC AND METABOLIC INDICATIONS

ENERGY PRODUCTION AND ANTIOXIDANT PROPERTIES

CoQ10 is a lipophilic substance (or fat-soluble nutrient) and is therefore absorbed in the gastrointestinal tract by the same method as lipids, such as vitamin E.(2) Being hydrophobic and of large molecular weight, the absorption of dietary CoQ10 is enhanced in the presence of lipids or fatty meals. Secretions from the pancreas and bile acid facilitate emulsification and micelle formation that is necessary for the absorption of CoQ10 in the small intestine.

In a study examining the absorption rates of CoQ10, 60 subjects were divided into 4 groups and administered 100 mg of CoQ10 daily. Group 1 took Bio-Q10 in a soft capsule, Group 2 Bio-Q10 in a hard capsule, Group 3 CoQ10 (ubiquinone) in a soft capsule and Group 4 CoQ10 (ubiquinone) in a hard capsule. After 3 weeks, the highest absorption rate was seen in group 1 (1624 ng/mL), followed by group 2 (985 ng/mL), then group 3 (1066 ng/mL) and then group 4 (737 ng/mL).(6) In an animal study, researchers divided rats in to 6 groups and administered 100 mg/kg of regular ubiquinone with one of four emulsifiers (sorbitan stearate, polysorbate 80, glycerin esters or fatty acid, or propylene glycol state), ubiquinol or Bio-Q10. Three hours later, the plasma concentration was measured. In the four groups who received the emulsified ubiquinone, levels ranged between 0.75–1.25 g/ml; the ubiquinol group was 3.0 g/ml, and the Bio-Q10 group measured at 3.2 g/ml. This demonstrates that the absorption of the Bio-Q10 was comparable to ubiquinol and between 2.5–4.25 times that of the emulsified ubiquinone.(7) CoQ10 is packaged into chylomicrons and transported via the lymphatics to the circulation.

Being mostly carried by VLDL/LDL particles, plasma CoQ10 concentrations are highly dependent on plasma lipoproteins. In the human circulatory system, about 95% of CoQ10 in circulation exists in its reduced form as ubiquinol. CoQ10 is most concentrated in tissues with high energy requirements such as the heart, brain, liver, muscles and kidney. Studies show that with chronic dosing, there appears to be a dose-dependent relationship between supplementation and CoQ10 tissue levels for oil-based, powderbased and solubilized formulations of CoQ10.(2)

UBIQUINONE VS. UBIQUINOL

CoQ10 is found in the body in two forms: ubiquinone and ubiquinol. Ubiquinone is an oxidized form of CoQ10 that is used to create energy. Ubiquinol is the reduced form of CoQ10 that is used to provide antioxidant protection. Both of these forms are needed and used by the body, and it is the location in the body which will determine which form CoQ10 will take. For energy production inside cells, ubiquinone is used and outside cells for antioxidant function, ubiquinol is the form the body uses. Ubiquinone and ubiquinol form a redox pair, which means the body can easily convert from one form to the other.

Ubiquinol taken in supplement form is unstable and is converted back to ubiquinone before it is absorbed. Oil-based ubiquinol does, however, have improved bioavailability over powdered ubiquinone with absorption.(6)

SAFETY AND CONTRAINDICATIONS

CoQ10 has an excellent safety record. The observed safe level risk assessment method reveals strong evidence of safety at intakes up to 1200 mg/day.(1) Adverse effects with CoQ10 supplementation are rare, with <1% of the patient population reporting GI discomfort.(3) There may be potential interactions with warfarin (Coumadin), and due to CoQ10’s potential hypoglycemic and hypotensive effects, discuss adjunctive use of CoQ10

In Parkinson’s disease, CoQ10 may be used for slowing of functional decline. A clinical trial of 80 patients supplementing 1200 mg/day of CoQ10 experienced 44% less functional decline.(13) Furthermore, CoQ10 also has demonstrated positive trends in improving metabolism and physical endurance and reducing symptoms associated with selected mitochondrial diseases.(3, 9) In early Alzheimer’s disease, evidence from human research suggests that CoQ10 supplementation may slow down, but not cure, dementia in patients.(9) In migraine studies, patients taking 150–300 mg/day of CoQ10 experienced a significant decrease in frequency (≥50%) of migraine attacks, and it was concluded that the number to treat was three.(3) Preliminary studies also show potential benefits of CoQ10 supplementation with Friedreich’s ataxia, as well as Huntington’s disease.(3, 9)

OTHER DISORDERS

Due to CoQ10’s hypoglycemic and hypotensive effects, CoQ10 supplementation has been studied in patients with type 2 diabetes.(14) A recent study supplementing 200 mg/ day of CoQ10 for 12 weeks observed improved blood pressure and glycemic control in type 2 diabetes patients; however, these results were not associated with a reduction in oxidative stress. Since CoQ10 is vital in energy production, the effects of CoQ10 supplementation on exercise performance in athletes and normal healthy adults have been studied; however, results are variable.(9) Preliminary studies in periodontitis (gum disease) have also observed improvements in bleeding, swelling and pain with oral or topical application of CoQ10.(9) CoQ10 can also have an impact on fertility. A study performed on human seminal fluid found that seminal CoQ10 concentrations have a direct correlation with seminal parameters including count and motility. Changes in CoQ10 levels were associated with conditions involved in male infertility, including asthenozoospermia and varicocele.

In two separate studies looking at idiopathic asthenozoospermia, researchers found that CoQ10 in the ubiquinol and ubiquinone forms were significantly increased in both sperm cells and seminal plasma after treatment. Researchers concluded that patients with lower baseline levels of motility and CoQ10 levels had the highest probability to be responders to treatment and that exogenous supplementation of CoQ10 can be effective for improving idiopathic asthenozoospermia.(15)

Bio-Q10 SAP

Science-based soy-emulsified coenzyme Q10 for optimal absorption Coenzyme Q10 is produced by the human body and is necessary for the basic functioning of healthy living cells. It has 2 main physiological roles: energy production and antioxidant protection. Without CoQ10, the chain of cellular energy is broken and without energy, cellular life ceases. CoQ10 levels decrease with age and are even lower in patients with chronic diseases. Prescription drugs, including statins, may also lower CoQ10 levels, yet they can be increased by supplementing with CoQ10. Bio‑Q10 has the ability to be absorbed 2.5–4.25 times more efficiently than the standard ubiquinone form of CoQ10.

ACTIVE INGREDIENTS

Each vegetable capsule contains:

Bio‑Q10 (Coenzyme Q10) (Ubiquinone‑10 from Japan) (Bacterial fermentation) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 100 mg

Contains no: Preservatives, artificial flavor or color, sugar, dairy, starch, wheat, gluten, yeast, citrus, corn or egg.

Bio-Q10 SAP does contain soy.

Bio-Q10 SAP contains 60 vegetable capsules per bottle.

ADULT DOSAGE

Adults: Take 1 capsule two to three times daily or as directed by your health care practitioner.

INDICATIONS

ɶ Bio‑Q10 provides protection against cardiovascular disease. ɶ Bio‑Q10 has the ability to transfer electrons and therefore acts as an antioxidant. ɶ Bio‑Q10 can help prevent deficiency from statins medications. ɶ Bio‑Q10 can help treat idiopathic asthenozoospermia, which can contribute to infertility. ɶ Bio‑Q10 may be helpful in slowing decline in Parkinson’s patients. ɶ Bio‑Q10 may help lower blood pressure and improve glycemic control in patients with type 2 diabetes.

HIGH-BIOAVAILABILITY FORM OF UBIQUINONE

NFH’s Bio-Q10 SAP is manufactured by blending a unique emulsifier—a specific soy protein—with CoQ10. The protein is ideal for blending with CoQ10, as it has both a hydrophobic and hydrophilic component. The water‑insoluble components are dispersed with the emulsifier in water and are then absorbed well in the small intestine. Bio‑Q10 has the ability to be absorbed 2.5–4.25 times more efficiently than the standard ubiquinone form of CoQ10.

PURITY AND STABILITY

Third‑party testing is performed on the finished product to ensure Bio-Q10 SAP is free of heavy metals, pesticides, volatile organics and other impurities.
