I am both honoured and privileged to present you the first publication of Brock Health! The purpose of this academic publication is to enhance the peer-to-peer educational experience and to inform the student body of current health research. This magazine covers a wide range of topics from public health issues to treating cancer because health care these days is also taking more of a multidisciplinary approach. It is through this manner that we can achieve the best health results for the community.

For a long time, it was thought that saturated fats were the most dangerous type of fat. It was recently determined, however, that trans fats are responsible for 2.5–10 times more risk of ischemic heart disease than saturated fats.1 Trans fats not only increase ‘bad’ LDL cholesterol levels, but reduce levels of ‘good’ HDL cholesterol. They also raise triglyceride levels in the blood, and impair endothelial function resulting in vasoconstriction and inflammation.2 Worse still, trans fatty acids affect gene expression by inserting themselves into cell membranes, which increases the risk of many chronic illnesses, especially after a lifetime of consumption.1 As a result of their detrimental effects, Health Canada urges citizens to consume as few trans fats as possible, if any at all,3 and mandated their labelling in 2005.4

Academic Advising Why Should I Bother?

Jackie Robb, CHSC Undergraduate Program Coordinator & Advisor As you (hopefully) know, the Department of Community Health Sciences has a full-time Undergraduate Program Coordinator that is available to help guide students in areas of course selection and registration, career guidance, and to help you navigate your way through University. Many of you have come in for appointments and I love getting to know students faceto-face. In this electronic world, it’s nice to actually meet the people behind the email conversations so I can get a better feel for your personality, interests and goals. One of my main tasks is to provide academic advising to majors and prospective students in the Department. I encourage all students to make at least one advising appointment per year to ensure you are taking the proper courses to satisfy your degree requirements. These appointments can be very quick (and painless), taking between 10 – 30 minutes depending on the number and type of issues that we discuss.

SUDOKU!

Some of the things we can discuss in an appointment: • Degree and course requirements • Internship and Directed Reading opportunities • Time management pertaining to the scheduling of courses and non-academic activities • Graduate studies – prerequisites that may be needed and other application requirements • Career goals and prospects • Getting involved at Brock and in Niagara – why and how For the inaugural edition of the Brock Health publication, I was asked to provide some course reviews and I eagerly accepted. However, as I began to think about writing these, I realized that I can’t really provide a ‘review’ of a course because everyone has a different experience, and, I haven’t taken every course offered in the Department!

Five Ways to Pass! CHEM 2P20 according to Yumna

So, instead here are some tips for course selection: • Think about what you want to do after your undergraduate degree at Brock. Work? Graduate school? Second undergraduate degree? • There are so many options, but it’s important to take some time to figure out some areas of study in which you have an interest (rather than taking a course you are not at all interested in, but that fits into your schedule) • Narrow your options down to a few general areas - this will help guide your course selection because you can fit in prerequisites that may satisfy requirements for a few different graduate programs rather than taking random courses • Don’t overwhelm yourself - it’s ok to take four courses instead of five; if you know a course is very challenging and may require extra time, it’s better to take an extra term or year (or take spring/ summer courses) and do well in all of your courses, than to take five but have your other marks suffer because you had to focus so much on one class – lots of students do this! I wish you all the best this term – don’t be afraid to stop in to say hi or to make an appointment!

Stress, It’s a Killer Yumna Ahmed Today, academics are becoming more important and have a huge impact on one’s future and eligibility for a career. University students planning to enter the work force in their future must become very educated and knowledgeable in their field of interest. Yet with assignments, tests, essays, presentations and deadlines to be met along with other commitments other than academics such as sports and social events, university proves to be very stressful. High levels of stress in the lives of university students lead to negative effects that must be dealt with properly. Some serious negative effects include anxiety and depressive disorder, gastrointestinal disorder and a weakening of the immune system. Anxiety is a feeling of fear and is experienced by everyone. Some symptoms are sweating, nausea, hyperventilation, tachycardia, dizziness etc. University students have high amounts of anxiety and stress because of all the problems and challenges they must face in this transitional and developmental period. 1 Anxiety disorders make it difficult for one to live a healthy fulfilling life. University students are very susceptible to these disorders due to the stress in their lives. There are many treatments such as behavior therapy, cognitive therapy, relaxation exercises such as meditation and prescribed medication. Many anxiety disorders lead to depressive disorders. Symptoms of depressive disorder are having low energy, loss of appetite, decrease in level of physical activity, loss of interest to maintain relationships, lack of sleep and suicidal thoughts. Depression can lead to major depression, dysthymia and in some cases bipolar disorder. 1 Major depression includes exces5

sive crying, and the body feeling very sore. Some treatment methods for depressive disorder are psychotherapy, electroconvulsive therapy, and medication.2 Another effect that is linked with anxiety and depressive disorder that university students experience due to high levels of stress is gastrointestinal disorders such as irritable bowel syndrome (IBS). Those with IBS have psychosomatic and psychological symptoms such as depression, insomnia, cramps, bloating, headaches, anxiety and back ache.3 IBS has an impact on one’s interpersonal relationships, social connections and overall quality of life. Treatments for this syndrome are learning to manage stress, avoiding caffeine, taking medications, increasing fibre in one’s diet, emotional treatment and psychological help. One more negative effect that university students may experience due to high levels of stress is the weakening of the immune system. People with high levels of chronic stress tend to have fewer white blood cells than the average amount. Stress increases the likelihood to catch infectious diseases, the seriousness of the infectious disease, lowers the immune system’s ability to accept vaccines and slows healing.4 Stress actually prolongs the release of neurotransmitters and hormones from the endocrine and nervous system which assist with the functioning of the tissues and the

nerves in the body. So, a long period of inactivation of these areas will have damaging and negative effects on the human body. Some treatments are simply having a well balanced diet, setting achievable goals, drinking lots of water, exercising, learning how to manage stress, and developing a strong support system. Thus, high levels of stress in the lives of university students have negative effects that must be dealt with and treated effectively and properly. Some negative effects are anxiety, depressive disorder, gastrointestinal disorder and the weakening of the immune system. Learning to cope with stress is an important life skill. Some techniques one can use to deal with stress are to do something they enjoy everyday, talk to friends/ family, visualize positive things and treat one’s body right. Taking responsibility for one’s life, being aware of one’s choices, setting goals and being organized are other useful techniques. University students should be educated and knowledgeable about stress and how to deal with it, in order to live physically, emotionally, mentally and socially healthy lives.

Food Deserts

Healthy eating in a Drive-Thru city

Brent Gilliard Since the end of the Second World War, cities have sprawled with the construction of low-density, single use neighbourhoods on the fringes of existing urban areas. Many jobs have followed residents out of the city centre and urban areas have increased in size much faster than their populations. This new urban form is well suited to the automobile, but to the exclusion of all other modes of transportation.1 Living in the modern North Ameri can city, a car is usually needed to perform the most essential tasks, like commuting to work. As automobile ownership approaches (but does not reach) universality, the minority of people or households without a car are left “transport-deprived”. The most apparent alternative, public transportation, poorly serves low-density neighbourhoods by nature of their spatial structure (i.e. culs-de-sac)and dispersed demand. Individuals and families without a car are left with few good alternatives for accessing important but distant destinations.2 March 2010 - Issue 1

Of importance, there is a tendency for grocery stores to close down in older, poorer, neighbourhoods, while new supermarkets open in the affluent suburbs. The unequal distribution of supermarkets has a disproportionate impact on transportdeprived people. When a neighbourhood with a high proportion of zero-car households loses its local supermarket, it can become part of a phenomenon known as a food desert, a socioeconomically disadvantaged area with limited food retail choices.3 Accessibility of supermarkets is important because they provide a wide selection of healthy foods at a reasonable cost. Convenience stores, on the other hand, carry a narrower selection of healthy food, and, according to a survey of Waterloo, are about 60% more expensive than supermarkets4. The problem then is, that supermarkets would be most helpful for low-income, low-mobility people but are the least accessible, while accessible retailers offer high-cost, unhealthy foods.5

It is widely accepted that unhealthy diets play a major role in the rising global burden of chronic, non-communicable diseases including type II diabetes, cardiovascular disease, and certain cancers. Of particular concern is “elevated consumption of energy-dense, nutrient-poor foods that are high in fat, sugar and salt.”6 While research proving that low-income Canadians are eating less healthy than other Canadians is limited, in other Western, industrialized countries, people with high socioeconomic status tend to eat more fruits and vegetables but less fat, oils, and meat. It is reasonable to expect these trends to exist in Canada.7,8 Access to supermarkets is not the only variable that determines healthy eating among low-income Canadians. The causes of unhealthy eating and ultimately obesity are often conceptualized as a causal web. There are dozens of interconnected elements at all levels, from global to local, that help or hinder healthy eating, including advertising, culinary culture, and the cost of food.8,9 The appearance of food deserts in cities is an important example of how decisions that seem unrelated to health (proximally, urban planning and the operating practices of supermarkets) can have profound impacts on the health of many people.

ADHD

Treatment with drugs or therapy?

Kresimir Mijaljevic Attention deficit hyperactivity disorder (ADHD) is a “problem with inattentiveness, over-activity, impulsivity, or a combination” beyond what is normal for a child’s age and development.1 It is more commonly diagnosed than any other behavioural disorder in children, affecting approximately 3-5% of school aged children; it is more common in boys than in girls.1 In Canada, 35% of all children referred to mental health clinics are diagnosed with ADHD.2 A prominent form of treatment noted in clinical settings was with the administration of Sertraline – marketed as Zoloft. Issued in 1996, Zoloft was developed by Pfizer for the purposes of treating Obsessive Compulsive Disorder (OCD). It is the Food and Drug Administration’s obligation to make certain that the therapeutic agent must ensure safety and efficacy.3 Hinshaw argues that “medication is the only viable option for treating children with ADHD, and that behavioural intervention strategies are not important for treating the core symptoms of ADHD”.4 A significant problem that arises with the administration of any drug is the problem of physiological dependence and proper adherence to the regimen. By offering a medicinal form of intervention for the treatment of a psychological disorder, new conditions and challenges arise in evaluating the efficacy of the treatment. Furthermore, the initial concern becomes a problem at the regulatory level. On the contrary, The National Initiative for Children’s Healthcare Quality supports a chronic care model that accounts for teens and adolescents, and their families requiring supports in addition to an individualized and appropriate clinically based program.5 Lilienfield examines the treatment of 7

ADHD in the psychosocial domain.7 She notes that cognitive-training therapy programs help enrich a child’s way of expressing an underlying psychological barrier that cannot be otherwise expressed in communicated words. The play therapy was based on the notion that integrating toy props such as dolls and other inanimate play objects to help the child express an underlying psychological conflict. In reality, these programs help highlight the child’s self-control problems by communicating self-instructional skills to advance their ability to ‘stop, look, listen’. Lilienfield highlights the fact that some controlled studies mainly focus on school-based behavioural interventions which focus on the positive reinforcement of attention sustainability.6 This exemplifies the simplicity in treating a complex disorder, in that the elementary constructs of the child’s mind are examined and manipulated in such a way to highlight undeveloped or repressed parts of the psyche. Similarly, Chronis and colleagues, examined both behavioural parent training and classroom behaviour management, in a study evaluating psychosocial treatment for children and adolescents with ADHD in a school setting.8 The study was directed toward teaching parents and teachers to implement behavioural modification principles supported by social learning principles, targeting deviant behaviours, using praise and positive attention, as well as rewarding exemplary and improved behaviour. Thus, Chronis highlights a potentially successful redirection in treatment of ADHD, which can serve as a model for many other mental disorders.7 This model highlights the importance of improving behavioural treatment and implementing it as a guide for enhancing the training of caregivers, educators, and parents working with children plagued by this

disorder. It is clear that medicinal interventions have significant immediate effects on mediating and controlling psychosocial disorders, but for the health and well-being of the child treatment models must be re-examined. Similarly, behavioural models demonstrate the positive implications upon the child’s psychological framework as well the child’s overall wellbeing. Truly, positive implications on the individual will lead advocates to encourage various collaborative programs to help treat and possibly reduce the prevalence and future incidence of these disorders in our society. However, this will likely be a constant battle against the pharmaceutical industry since the best interests of the child will ultimately compete with the marketing of medicine in our society.

Medical ethics may as well be the law behind medical practice and research, and is directly related to the decisions made in diagnosis, medical treatment and lifestyle treatment of diseases. Currently, a particular bioethical debate is concerned with the invention of a 'smart pill'. Will it reshape civilization in the future, positively impacting one’s intellect? Dr. Jeynes is concerned with the impact this ‘smart pill’ will have on “personhood and individuality.” Surely, he

Cigarette butts that is. More than 36,000 of them Between March and April 2009, discarded cigarette butts were collected from the grounds of 25 post-secondary institutions in Ontario. Far from a garbage pick-up, these butts were collected with a research purpose in mind- to determine if post-secondary students in the province are using contraband tobacco. Contraband tobacco In simple terms contraband tobacco is cheap, illegal tobacco. A more official definition from the RCMP states contraband tobacco is any product that does not comply with the requirements of all federal and provincial laws.1 In other words, if the laws regulating the manufacturing, packaging or distribution processes are broken, or if appropriate taxes or duties aren’t charged, the tobacco is illegal; it is 9

Neglected Diseases

Poverty and illness out of sight Brent Gilliard Approximately 600 million people worldwide are infected with small intestinal parasites that feed on human blood, called hookworms (Necator americanus and Ancylostoma duodenale). The resulting blood loss can be so severe it causes anaemia, negatively affecting children’s growth, education, and future economic productivity. Importantly, there are safe, effective treatments for hookworm infection, yet we do not have the situation under control.1 This can be explained mostly due to the fact that hookworm infection is just one of several neglected tropical diseases (NTDs). Of the poorest billion people in the world, almost all have at least one NTD.2 Collectively, they reduce child health, hinder education, reduce productivity, disrupt social ties, and impose steep costs for medical care. These diseases thrive in conditions of poverty, and they trap people in it. The symptoms of NTDs are diverse, including anaemia, blindness, disfigurement, organ damage, severe itching, pain, and diarrhea (Table 1). What they share is a high burden of disability and low mortality rate.2,3 The resources marshalled against NTDs have been too few despite the billion or more people with these diseases. They have a collective burden of disability in excess of better-known diseases such as malaria or tuberculosis, but investment and even awareness have been stymied by the nature of NTDs. Most are not threats to wealthy nations, because they are tied to tropical environments and do not travel well, so there is very little self-interested investment by these governments or pharmaceutical corporations. Even within affected nations, NTDs are concentrated in marginalized populations where 11

they disable, rather than kill. Cashstrapped developing nations tend to focus on visible, highly fatal diseases like HIV/AIDS. Unfortunately, the stigma attached to some NTDs means that they are neglected by even neighbours and family members.4,5 Fortunately, many NTDs might be controlled or eliminated for as little as fifty cents per person per year.2 Mass drug administration, the treatment of entire populations with safe drugs, has proven effective and affordable for several NTDs. The drugs are often donated by multinational pharmaceutical corporations. (Not to look a gift horse in the mouth, but these are the same corporations that neglect new research and development.) When communities are trained to manage their own treatment programs the local health systems are strengthened and more people can be treated at lower cost. The burden of NTDs is already falling in some countries, thanks to successful interventions. The immediate challenge, therefore, is not developing new treatments; it is brining existing treatments to the people who need them.2,5 Despite remarkably low costs per person, NTDs are so widespread – remember, at least one billion people are affected – that $2-3 billion in financial assistance is needed in the short term to address the most important NTDs alone. This figure does not include the long term costs of managing NTDs. In addition to fundraising, there is also significant organizational work to be done; each disease and local health system is unique.2 Bringing NTD control to every person in the world is not a simple task, but it is a manageable task. It promises a tremendous return on investment by breaking a vicious cycle of disease and poverty for a billion people.

Neural Interfaces

Exactly as creepy as it sounds

In our modern world, it’s hard to believe that anything is impossible anymore. Decades ago, mind control was something read in a fiction novel or seen on television and film. However, in recent years, it has become a reality for many. Though nothing as extravagant as freely moving objects (yet), those with paralysis and amputations have and will benefit from a technology known as neural interface systems (NIS), also known as brainmachine interface (BMI) or bionics. Research on this relatively young technology is being developed in an effort to return accessibility to individuals with missing or damaged appendages. It helps to restore control, communication, and independence to those individuals with paralysis when the motor control structures are disconnected from muscle output.1

Singha Chanthanatham the brain to the target muscle. Anticipation of potential errors occurring will need to be considered in the design of the system in order to predict and prevent any possibility of misinterpreted movement, such as a slip of a handgrip. In a damaged brain this would produce a significant dilemma seeing as the initial intended movement might not be the most direct one. It requires a buffer for translation to extend the signal to the limb. The ultimate goal of this buffering can lead to a beneficial improvement in speed and accuracy, reaching a more natural, nearly unconscious level of use.2

One of the first times this exciting advancement was demonstrated was in a study conducted in North Carolina on primates, sparking lots of interest.

Nanomagnets Cancer Cured? Shahla A. Grewal The exciting field of magnetic nanoparticles is really picking up speed these days. The possibility of treating cancer through nanomagnets (hyperthermia and direct drug delivery) is slowly but surely materializing. The idea behind this approach is to artificially induce hyperthermia with the nanomagnets to kill cancer cells. This technology began in the late 1950s when Gilchrist et al at St. Luke’s Hospital in Chicago heated various tissue samples with 20-100 nm size particles of iron oxide.2 It has improved since then and will continue improving in the future.

Currently, the survival rate is approximately seven months, however, with this procedure they are hoping to increase it by at least three more months if not more.1 It is worth noting that not all of the work in this field appears in the scientific literature, but rather kept hidden in company patents or on the down low until commercialization of this technology is legally approved and full blown.3 So, for at least the next couple of months or years, the growth of such companies should be observed closely. All in all, this field is emerging and the future looks bright for the end of these vicious diseases. Whether it be now or a hundred years from now I believe cancer will be cured and that shining knight may very well be nanomagnetic technology.


Brock Heart Institute

Helping Hearts Steve Demetriades

Although we rarely hear about students making a difference in our community, Brock students are extremely important in the success of many community projects throughout Niagara both through Brock initiatives and individually. Students donate their time and energy to help and improve the lives of others within our community. One specific community project occurs at the Brock University Heart Institute (BUHI) located on Lockhart Drive at the base of the Glenridge hill. Within this Institute, desperately needed cardiac rehabilitation takes place in an environment that is extremely unique for volunteers, staff and members.

Peter, a member for over a year, says that the Institute has a great atmosphere and great people. “The volunteers really help make this place great. The atmosphere and friendliness really makes it easy to come back week after week” explains Peter. Brandon, a master’s student who prescribes exercises to new and existing members, states that research shows that only around 1/3 of people who begin treatment with exercise continue after 6 months.

Prescription Drug Abuse

What’s really going on? OxyContin. Prozac. Ritalin. For most of us, these aren’t your typical everyday items. However, popularized by every imaginable media outlet, be it from chastising celebrities or new health care technologies, prescription drugs and their abuse are increasing. If taken as directed by the doctor or physician, prescription drugs can offer relief and positive reinforcement. On the other hand, when not taken for the intended use, they pose certain dangers and hazardous consequences.

Exercise Motivation Mind Over Matter Michael Carrigan Have you ever looked at yourself and thought perhaps you should exercise more? Do you ever put your jeans on in the morning to find that they are a little too snug? When a friend of yours invites you to run with them would you prefer to stay in and watch TV? You need motivation to get you up and moving, though often this is hard to produce. Here are some helpful tips to get you moving in the right direction. I have found that a positive attitude can go a long way when contemplating exercise. If you want to feel and look healthier then you will be more obliged to exercise. Remember, exercising requires both mental and physical endurance, so if you can fight the urge to relax, that is half the battle. Once you begin to exercise you will feel healthier and more confident. The will to exercise will increase because you have felt its positive effects. If you find yourself stressed out from work and studying, physical exertion is an excellent way to relieve it. According to Cotman, Berchtold, and Christie, “This will stimulate brain activity and is recognised to increase memory and learning capacity, further protecting from neural degeneration and the alleviation of depression and stress.”1 By exercising you can relieve stress and simultaneously stimulate your brain so that when you return to study or work, you will retain more knowledge than if you had not exercised. If you find that what would typically be a long enough sleep does not make you feel rested or it takes a long time for you to fall asleep at night, exercise can increase March 2010 - Issue 1

the depth and effect sleep takes. A study done on athletes by the Journal of Adolescent Health reported a higher quality of sleep, shorter sleep onset, fewer awakenings during the night and higher concentration during the day.2 Having a regulated sleep pattern will reflect a positive outlook on life, study and work, in addition to higher attentiveness and healthiness. If the idea of running on a treadmill and staring at your watch discourages you from exercising then try something innovative. Take a trip somewhere like Chinguacousy Hill in Brampton and try skiing or snowboarding. These places offer classes once a week for beginners and are a great way to embrace the Canadian winters. If cold, wet snow is not your forte then perhaps a dance class in jazz or salsa will get your feet moving. This way, you will be exercising and learning a new skill as well. For something local and free, try going for a walk around the scenic Brock campus in the spring. Try participating in something active every other day for three weeks. Although it may hurt for some time, once you get into the habit, you will soon look forward to making your body and mind healthier. Exercising does not have to be an aggravating task; it should be a positive experience. It will increase your attentiveness, make your body and mind healthier and give you a better attitude and self-image.

HOT HEADLINES! “Health-care staff close to burnout, study finds” Katelyn Cullen Researchers say excessive demands on hospital staff and managers, and a culture of urgency, are fuelling stress and absenteeism The fact that one in three hospital employees are at risk of burnout suggests that it is time for hospitals to start caring for their employees, in addition to caring for their patients. The demands faced by hospital employees appear to be taking excessive tolls on their mental and physical health, with over half of the respondents reporting sleeping less, and 18% saying they had used alcohol or prescription drugs as stress relievers. Insufficient amounts of rest and use of drugs or alcohol can certainly hinder the performance ability of an employee during their following shift, which could ultimately jeopardize the safety of a patient. Implementation of a health care policy seems beneficial for employees, as it would provide them with the appropriate amount of time needed to rest and recuperate from an extensive shift, thus improving their performance and general state of health. It is questionable whether to allow an employee that faces such high demands, stress and work overload, to continue a shift past a specified number of hours – or to apply a regulation that limits the number of hours clocked, and enforces a time of recuperation. 16


Designer Babies

Build a Baby Hind El-Hussein

How far would one go to create the “trophy” child? Imagine a build-a-bear store filled with different shapes, sizes, colours and even stuffing’s to create your “perfect” bear. Now imagine the same concept except replace stuffed bears with human babies.This idea comes from a medical procedure known as pre-implantation genetic diagnosis, or PGD. PGD has been used for medical purposes to avert life threatening genetic disorders in children. Briefly, a three day old embryo that consists approximately six to eight cells are examined for genetic diseases, and the cells free of any disease are implanted back into the mother’s womb.1 This highlights the potential benefits of PGD. For example, frequently diagnosed disorders include cystic fibrosis, sickle cell disease, Huntington’s disease and myotonic dystrophy. But the advances in science are not limited to avoiding certain traits; it is now also possible to pick and choose certain traits (analogous to build-a-bear store). For example, parents could choose to have a green eyed, blonde hair daughter. To do this, first, a woman’s eggs are fertilized with sperm in a lab, creating several embryos. Then a single cell is removed from each embryo and tested for biomarkers associated for female gender, green eyes and blonde hair. Finally, only embryos with the biomarkers for the required traits are placed in the woman’s womb. The procedure guarantees that the child will be female, and increases the probability of having green eyes and blonde hair.2

back? Do you take legal action? It seems foolish, but believe it or not a couple in Utah are taking legal action towards the University of Utah medical centre for allegedly using the sperm of a donor, other than one they had originally selected. The mother gave birth to three healthy triplets, but claimed that if they had used donor #183 as opposed to #83 the children would have turned out better looking, and this caused her severe emotional distress. The judge ruled there was not enough evidence of emotional distress or bodily harm and the couple lost the case. 3 This is a clear example of parental control and the idea of creating the perfect child. The idea that all is wanted is a healthy baby no matter what he or she may look like, has been diminished. These parents are only being selfish and forgetting what is best for the child, and looking for personal gain. Just like we have created genetically engineered foods, crops and animals, it is inevitable that genetically engineered babies will be coming up in the next decade. The fact is that parents will always want what is best for their children. But does designing a child take it too far? Are parents now only feeding their own desires? On one hand, it reduces the chances of a baby being born with several serious diseases. On the other hand, there is a sense of playing God. The level of biodiversity will cease to exist, and there will be discrimination towards anyone who appears different. Furthermore, parents who decide their children’s traits, eliminates what the child has to say about his or her life.

HOT HEADLINES! “Sale of junk food to be banned in Ontario schools” Jacey Allardyce A ban effective the first day of school in 2011 on the sale of junk food in schools is intended to target the rise in childhood obesity Although this proposal is being met with mixed reviews, the regulation of foods sold in schools is an example of a preventative health care approach instead of addressing the issue of obesity when it is too late and more costly to the Canadian health care system. People may feel that this is some type of privacy invasion but students are still permitted to bring in their own lunches and having healthier options at school may inspire students to request healthier choices from their homes. Addressing obesity and the negative repercussions that can occur will no doubt save money in the long run.

Hot Headlines! “Diabetes Huge Problem on Canadian Reserves” Colin Horne Diabetes is spiralling out of control among aboriginal Canadians, with women being alarmingly affected, a new study of more than 90,000 people shows. As is well known when discussing aboriginal Canadians, the transition from a traditional and cultural lifestyle to a more sedentary one has created devastating health affects in aboriginal communities and raised many concerns for their health. With current conditions worsening by the year, changes must be made in order to help young aboriginal women most at risk of developing diabetes. Our current healthcare policies need to acknowledge the unique situation and needs of aboriginal Canadians and in particular aboriginal women, emphasizing preventative care strategies for areas and ages most at risk. By adjusting the accessibility to our healthcare and healthcare professionals in northern regions, many at risk aboriginal women would be able to gain the necessary education to reverse this worsening trend. “U.S. links bisphenol-A to health risk”

we would be more aware of issues like these, especially since BPA can be found in many common household items. There is still debate as to whether it is actually harmful or not but research has proven it to be harmful in animals. In my opinion, the fact that it is even remotely controversial is enough for me to think it should be eliminated from production. This issue also makes people wonder about the government and whether there should be more policies and regulations in place to help prevent issues like this from happening in the future. BPA is found in many things that we come into contact with on a daily basis. This causes one to question what else we are exposed to frequently that could slowly be affecting our health that we aren’t even aware of? ? Did the government drop the ball when it comes to policies to prevent the mass manufacturing of potentially harmful substances? “For sale: 1 farmhouse, great views, a bit smelly” Dan Harasymiw A century-old farmhouse included in Toronto's purchase of its new landfill site will be sold off

Talking distracts drivers, study finds” Katelyn Cullen Research discovers dramatic decrease in comprehension for drivers This study found that driving a vehicle affects how well someone talks or understands what is being said to them. With such attention being placed on the use of cell phones while driving, it’s no wonder that further investigations are taking place that study similar distractions - which may also hinder one’s ability to concentrate while behind the wheel of a moving vehicle. This article raises questions as to the number of passengers a driver should be allowed to cargo, when each additional passenger can apparently increase the distraction felt by the driver. If a policy, which limits the number of passengers allowed in a vehicle were enforced, should this be done among all age groups, or should this solely be limited to the new and often less experienced drivers? It is believed that a passenger limit would be quite difficult to enforce, especially with the manufacturing of larger vehicles that have the ability to hold up to seven people – as well as the notion that good drivers are able to concentrate on their driving and allow the other things they are doing at the same time to suffer.

Five Ways to Pass! CHSC 1F90 according to Kresimir

1. Do the readings prior to class and ask questions if uncertain about something. Use your resources. 2. Asking questions brings you one step closer to knowing something new and something that may be on the exam! 3. DO NOT miss seminars. You recieve participation marks for simply saying something relevant to the topic of discussion. Start early for your seminar presentation! 4. Dr. Faught likes stats on his exams. So be sure to jog your memory every once in a while with facts that he provides in class. 5. Be sure to set out time to look over your notes after lecture and once before the following lecture. This will minimize cram-time in the final hours before your exam.

Ontario's push to have family doctors work in collaborative teams with other health professionals is paying off financially for the physicians and is resulting in better patient care, according to the New England Journal of Medicine. Ontario’s desire to increase collaborative teams with family physicians and other health professionals is a good policy because it ensures that Canadians will have better patient care. The usual feefor-service model focuses only on the physicians’ advice and does not allow patients to seek other health professionals’ advice, unless there is a referral issued from their family physician whereas family health teams allow patients to have better care in a one stop shop experience. These multi-disciplinary groups expose physicians and health professionals to effective communication with sharing of expertise, which in turn, ultimately benefits the patients. Ontario’s policy for collaborative teams should be expanded throughout Canada to ensure that all Canadians have access to the best health care possible. Tahmina Taraky
