from the editor Welcome to a wide variety of articles for you to feast your eyes on and I hope there is something for everyone.

Chris Rudd NHD Editor Chris Rudd’s career in continuous dietetic service has spanned 35 years. She is now working part time with the Sheffield PCT Medicines Management Team, as a Dietetic Advisor.

Obesity in post liver transplant patients is an increasing problem which is under recognised with no definite guidelines for surveillance or treatment. Susie Hamlin and Julie Leaper’s comprehensive article Weight gain and obesity after liver transplantation provides that problem-solving approach of what to do, when and how. Keeping with the obesity theme, Mary O’Kane provides us with Bariatric surgery and the importance of nutrition. This article covers the eligibility for bariatric surgery and its impact on diet and nutrition and helps us learn more about NCEPOD, BOMMS survey and guidance and also about the GP guidance.

Pregnancy may be challenging for many mums-to-be, but have you thought about what happens if that mum-to-be has Phenylketonuria? Paula Hallam and Sarah Ripley explain Maternal PKU which includes the key challenges of the diet, including a case study of Nicola. The outcome is that 99 percent of the babies born to PKU mums will not have PKU, a truly healthy reward.

Prescribing costs and appropriate prescribing may be of interest to many who work with Medicines Management Teams.

Cows’ milk allergy seems to be a well discussed topic and this month; Juliana Scapin covers Cows’ milk allergy specialist formulae: appropriate prescribing. What do we need to know?

Again, it shows that a dietitian who is ‘advising the right product for the right patient for the right length of time, will not only save money, but can enhance patients’ clinical outcomes and safety’.

Patient feedback and receiving comments about their experience of care is vital and having the carer’s feedback is also welcomed. Home enteral tube feeding services - five years of change: a view from patients and carers looks at a small retrospective survey of home enterally tube-fed patients and their carers, conducted by Gillian White.

Positive outcomes and a patient-centred approach to care are highlighted.

The ketogenic diet has been used as a treatment for epilepsy since the 1920s, pre-dating most anticonvulsant drugs.

PaediaSure Peptide. Contains all the nutrition a funny tummy needs.

(As recommended by Dr. Alex, age 5).

Life can be hard when playtime is ruined by the symptoms of malabsorption and poor feed tolerance. So if over 7% of paediatric patients experience gastrointestinal (GI) symptoms in the two weeks before they start an ONS,1 isn’t it important to get them on the right one first time? PaediaSure Peptide is formulated with 100% peptides to effectively manage impaired GI tolerance. And with a taste that most children prefer,* changing over from a whole protein ONS is child’s play. 2

Nuts and blood pressure: New metaanalysis

New EUFIC article on gestational diabetes

Dr Emma Derbyshire PhD RNutr (Public Health) Nutritional Insight Ltd

Gestational diabetes is fast becoming a rising health concern in pregnancy. Now, a new article published for the European Food Information Council (EUFIC) looks into the wider implications of this.

Most importantly, gestational diabetes (i.e. when a woman’s blood sugar levels in pregnancy become higher than normal) can affect the health of the mother and her baby. Over-growth of the foetus, leading to the delivery of larger babies (macrosomia) and subsequent delivery complications, are the main concerns, along with increased risk of pre-eclampsia.

Being a healthy body weight before becoming pregnant, being physically active, eating a diet that includes plenty of wholegrains, lean proteins, oily fish and polyunsaturated and monounsaturated fats, are key messages that should be communicated to women of childbearing age. Intakes of foods and drinks with a high glycaemic index should be kept to a minimum.

For more information see: Derbyshire EJ (2015) Food Today. Available at: www. eufic.org/article/en/artid/The_rising_ concern_of_gestational_diabetes/

Past work has looked at how certain nuts affect blood pressure, but findings have been mixed. Taking this on board, a new meta-analysis has pooled data from 21 randomised controlled trials.

Findings showed that pistachios significantly reduced systolic blood pressure (P=0.002), while both pistachios and mixed nuts led to significant reductions in diastolic blood pressure (P=0.04). These findings were most apparent in subjects without Type 2 diabetes.

Overall, eating pistachios may help to reduce both systolic and diastolic blood pressure in healthy adults without Type 2 diabetes. Eating mixed nuts may also help to lower diastolic blood pressure.

Eating habits which are not in line with our evolutionary progress are thought to be fuelling an epidemic of obesity and diet-related diseases, such as cancer and cardiac problems.

Now a new review has looked into this in more detail.

The article exploring how nutrition influenced the development of Homo sapiens concluded that genetically, we are still stone-age hunter-gatherers who thrive on lean meat, fruits, vegetables and nuts, but, environmentally, we are surrounded by foods laden with sugar, simple carbohydrates and the wrong type of fats.

Overall, the evidence base identified that we were likely to have evolved as

omnivores with animal products playing a key role in brain development and acquisition of skills. In addition, the same evidence noted that trialists who ate a diet of lean meat, fruits, vegetables and nuts, while avoiding cereal grains, dairy and legumes had lower blood pressure and lower blood levels of glucose, LDL cholesterol and triglycerides after just 10 days. And other evidence revealed significant reductions in body weight, waist measurement and blood pressure.

Hence, later shifts towards a cerealbased diet are likely to have happened too suddenly for our genome to adapt appropriately. This, in turn, is likely to have increased non-communicable disease risk.

Main sources of sodium after birth

Sodium intakes are high in the US and this trend starts early in life. New data from the highly-regarded National Health and Nutrition Examination Survey (NHANES 2003-10) has now looked into the main exposures during the first two years of life.

Data was analysed from 778 infants aged 0-5.9 months, 914 infants aged six to 11.9 months and 1,219 toddlers aged 12 to 23.9 months. It was found that sodium intakes were lowest in the youngest children but exposures increased with age.

With weaning (six to 11.9 months) commercial baby foods, soups and pasta mixed dishes provided extra sodium. In the oldest age group cheese and sausages were some of the main sources of sodium. Restaurant foods also provided nine percent of sodium.

Overall, this shows that most sodium comes from foods other than infant formula or human milk once children begin weaning. It also highlights the need to educate parents about how restaurant settings can increase children’s exposure to sodium.

For more information see: Maalouf J et al (2015) American Journal of Clinical Nutrition Vol 101 no 5, pg 1021-1028.

Parents influence on children’s eating habits

Emotional eating can lead to childhood obesity, but where does this stem from? Now, latest work has looked at how parental control in early life may play a role in this.

The study recruited 41 parents with a child aged between two and five years. Baseline data about feeding practices was collected and then families were followed up again two years later. At this point parents were observed feeding their children who were then exposed to an emotional stressor or a control and snacking habits were monitored.

Results showed that parents who used food as a reward, or restricted food for health reasons in the earlier years, were more likely to have children who ate more under conditions of negative emotion at age five to seven years.

These are interesting findings implying that parents who overly control their children’s food intakes may be doing more harm than good.

This may inadvertently lead to children relying on palatable foods to cope with negative emotions.

For more information see: Farrow AV et al (2015) the American Journal of Clinical Nutrition. Vol 101 no 5, pg 908-913.

Taking a look at the German National Nutrition Survey II As well as looking at food intakes in the UK, it’s important to look at trends in other parts of Europe. New data has now been published from the German National Nutrition Survey (NVS II) which measured food intakes in 15,371 subjects aged 14 to 80 years, comparing this with German Nutrition Society (DGE) guidelines.

The survey found that German men consume twice as much meat and soft drinks and drink six times more beer than women. Women, however, tend to eat more vegetables and fruit and drink more herbal/fruit tea. Older subjects consume less meat, fruit juice/nectars, soft drinks and

spirits, but more fish, vegetables, fruit and herbal/fruit tea than younger adults and teenagers.

People from lower socio-economic groups also eat more meat/meat products and drink more soft drinks and beer.

Overall, these findings show that German males, younger populations and lower socioeconomic groups have the most concerning food intake patterns, with a tendency for these to fall short of official dietary guidelines.

Latest on wholegrains

Wholegrains (WGs) are undoubtedly important for health, but, at times, comparing findings between studies can be cumbersome.

Now, conclusions from a new paper published in The American Journal of Clinical Nutrition recommends several approaches to ease this. These include reporting WG intakes in grams, as dry weight; defining the term WG in the paper; describing the different types of grain used; describing the structure of grains used, i.e. intact, crushed, partially milled etc; describing the products and processes used to make the WGs. Most recently, median WG intakes (on a dry weight basis) were measured in the UK 2008-11

BDA to support a new award in memory of Pat Judd and her work

In memory of Pat and her work, her family and friends have set up a BDA award with the aim to raise enough money to cover the support of a PhD for a dietitian.

The details have not yet been finalised, but those wishing to contribute to the award are invited to do so.

Please send a cheque made out to the BDA General and Educational Trust, addressed to Pat Judd Memorial Award, c/o Andy Burman, Secretary to the Trustees, The British Dietetic Association, 5th Floor, Charles House, Queensway, Birmingham, B3 3HT.â&#x20AC;&#x2122;

National Diet and Nutrition Survey. Data analysed from 3,073 people showed that median WG intakes were 20 grams per day for adults and 13 grams per day for children, with teens and young adults having some of the lowest intakes.

Interestingly, 18 percent of adults and 15 percent of children/teens did not report eating any WG foods at all.

A second paper by the same team of scientists also showed that adults with the lowest WG intakes had significantly higher levels of C-reactive protein (a marker of inflammation).

Consumers eating WGs also had nutrient intakes that were more closely in line with dietary reference values for fibre, magnesium and iron and lower intakes of sodium, indicating that higher WG intakes may also be associated with improved diet quality.

These are important findings, highlighting the need to continue encouraging WG consumption, especially amongst teenagers and young adults. Improved reporting in studies will also enable high quality meta-analysis papers to be complied in the future.

The importance of tender loving care: Elsie Widdowsonâ&#x20AC;&#x2122;s research in Germany

Ursula Arens Writer; Nutrition & Dietetics Ursula has spent most of her career in industry as a company nutritionist for a food retailer and a pharmaceutical company. She was also a nutrition scientist at the British Nutrition Foundation for seven years. Ursula helps guide the NHD features agenda as well as contributing features and reviews

Dr Margaret Ashwell, OBE, PhD, FAfN, RNutr (Public Health), Research Fellow Dr Margaret Ashwell has been a Senior Research Scientist with the Medical Research Council, Science Director of the BNF and an Independent Consultant, working for government and industry. She is an author and editor of the biography of the nutrition pioneers, McCance and Widdowson. She was appointed an OBE in 1995 and was elected as a Fellow of the Association for Nutrition (AfN) in 2012.

Dr Elsie Widdowson (1906-2000) was an extraordinary pioneer dietitian and the fact that the BDA annual lecture bears her name is just one of the many ways that her achievements continue to be recognised. A tribute to her and Professor Robert McCance was edited by one of the authors (MA) and published by the British Nutrition Foundation in 1993. Their joint professional timeline spanned 60 years, but some of their most fascinating research adventures occurred during their time in bleak, post-war Germany.

In 1946, the Medical Research Council suggested that funding was given to Robert McCance and Elsie Widdowson to examine how war and extreme food shortages had affected the German civilian population. They toured many cities and found that the hospital in Wuppertal had the best laboratory facilities, but especially of interest, was the presence of a completely bilingual English-German doctor who was anxious to support their research.

What had started as a six-month project stretched into three years of data collection.

One of the projects that Elsie led, was an examination of the effects of different kinds of bread on growth.

This was specifically to support decisions on post-war bread specifications, for although the war time national loaf made from high extraction flour was healthy, it was unpopular. In January 1947, Elsie found a suitable orphanage in Duisburg for the bread feeding experiments. The children were all underweight and under height and for 18 months they were fed five different diets where 75 percent of energy was provided by bread. The breads were made from one of five types of flour: 100 percent (wholemeal), 85 percent and 72 percent extraction (white) and two white flours enriched with B vitamins and iron by a smaller or greater amount. In addition, all flours were for-

NHDmag.com July 2015 - Issue 106

tified with calcium carbonate. Conclusions were that all of the breads were equal in relation to supporting growth in the children. Elsie announced her results at the annual conference of the British Medical Association and, in a time before PowerPoint, presented five of the girls, one from each of the different bread groups, and challenged the learned audience to detect any differences (there were none). Perhaps not the most scientific way to document the effects on growth of different diets, but a very exciting adventure for some young German orphans and a very interesting visual aid for the learned medics.

Another project that Elsie led was an examination of the effects of providing additional bread to the meagre baseline diets of young children. In 1948, Elsie recruited two small municipal orphanages which each housed about 50 children between the ages of four and 14 (the average age was just under nine). The children were all short and thin and would be weighed every fortnight for a year. For the first half year, all children would be on the normal official rations and for the second half year, children at one of the orphanages would be given unlimited amounts of additional bread to fully satisfy their appetites, along with some extra margarine/jam and concentrated orange juice.

PROFESSIONAL PROFILE

The results observed in the first six months were peculiar. Although all the children appeared to consume the same diet, changes in weight and height were different. At one of the homes, children gained exactly the predicted average amount of 1.4kg weight. In contrast, children in the other home gained on average less than 0.5kg.

The results in the next six months were even more peculiar. In complete contradiction to prediction, weights and heights of the children kept on standard meagre rations increased significantly. Children given the extra bread rations grew at only modest levels and, astonishingly, after the six month period, their average weights and heights were below those of the children in the orphanage not receiving supplementary foods. The observations were completely bizarre because weights had been so systematically collected, the food intakes so carefully measured and observed. The results

seemed absurd and Elsie was mystified.

Elsie was busy, but always had time to care for the little things that needed thought and attention. Lois Thrussell was a research nurse tasked with doing all the measurements for the energy and mineral balance studies. But Lois was unhappy about the fact that she had been commanded out of a room in the orphanage; she had to do her research in a hen house. The issue of concern was that the hen house had whitewash on the walls, but it was prone to flake off and ruin the calcium balance measurements. Elsie was the Miss Fix-it, and found an expensive piece of cretonne to drape over the walls. But Lois was still full of tears and told Elsie of her anxieties over the way that the orphans were treated by the very harsh and vindictive housemother. Mealtimes were dreaded by the children, because this was the time in their day for public scorn and rebuke over trivial misdemeanours.

Of course, it would be impossible to repeat or confirm the research. But in poetic form, she included in her 1951 Lancet paper, the biblical reference from Proverbs that, ‘Better is a dinner of herbs where love is, than a stalled (fattened) ox and hatred therewith’.

More than 20 years ago, one of the authors (MA) was able to get Elsie to pull together her thoughts on research into a very short list of golden nuggets of advice, and many of the items reflect outcomes from her projects in Germany.

This guidance, resulting from 60 years of research into nutrition science, is still valuable to dietitians and other researchers today and is the essential share-it item.

Advice to a young scientist by Elsie Widdowson Elsie went to investigate and was able to confirm the constant fear of the children over public and victimizing reprimand by the housemother at mealtimes. Food would be cold and children would be in tears. Further examination led Elsie to find out the amazing coincidence that the ‘dragon-lady’ had transferred from one of the orphanages to the other (the one being given the additional bread) at exactly the six-month changeover period of the project. During the dragon-lady’s reign at the first orphanage, the children gained nearly one kilo less than at the second orphanage, despite identical food rations. During her reign at the second orphanage, growth in the children decelerated to the point that weights were below those of children not receiving the additional bread and juice. Elsie further discovered that the dragon-lady had a few particular favourites; children who could do no wrong in her eyes were always given praise.

When she transferred between orphanages, she was able to transfer eight of these children with her; in the year of the project, the favourite children gained on average four kilos: one kilo more than any of the other children.

Elsie concluded from her study that psychological stresses due to harsh and unsympathetic handling could seriously curtail growth 12

Cows’ milk allergy specialist formulae: appropriate prescribing.

What do we need to know?

Juliana Scapin Paediatric Dietitian, Central London Community Healthcare NHS Trust

Food allergy is a recognised healthcare problem, with cows’ milk protein being the most common food causing allergy symptoms in infants and young children (1). It is established that the management of cows’ milk protein allergy (CMPA) following the diagnosis is complete or individualised avoidance of cows’ milk protein alongside the usage of suitable substitute milks.

Breast milk is suitable for the majority of infants suffering from CMPA, and mothers normally do not need dietary restrictions unless their infant presents symptoms whilst being breastfed (2).

However, when breast milk is not available, advice on a suitable milk alternative is needed.

Cows’ milk allergy specialist formulae spend has been increasing significantly in the past years (3). It has been reported that the NHS spends £23.6 million per year on paediatric cows’ milk protein allergy management (4). It is estimated that the NHS cost of managing an infant suffering from CMPA with extensively hydrolysed formula (EHF) over a period of one year would be £1,853 and with amino acid formula (AAF) this would be

£3,161 (5). Considering the NHS current financial situation, inappropriate spending has to be avoided (6).

Adding to future savings, the NHS aims to improve the quality of patients’ care (6), and it is known that appropriate prescribing can improve patient outcomes and safety (7). Therefore, it is essential to ensure that cows’ milk allergy specialist formulae are correctly and timely prescribed and reviewed.

REASONS THE SPEND ON COWS’ MILK ALLERGY FORMULAE IS RISING

Cows’ milk allergy specialist formulae expenditure is progressively increasing in London over the years and is significantly higher compared with other specialist paediatric nutritional products.

paediatric food allergy The following factors are believed to have been contributing to this (7): • increasing research in allergy, which leads to increased awareness of CMPA; • rising cost of products; • AAF being used inappropriately as first line, by some; • inappropriate initiation and/or prolonged usage of products caused by: - disparity in HCP knowledge about CMPA management and products; - poor communication to GPs, e.g. incomplete correspondence from HCPs recommending cow’s milk allergy specialist formulae in regards indicators for changing/stopping/reducing formula; + volume of prescriptions (number of tins per month); - GPs not acting as correspondence’s advice from specialists; - patients not reviewed by a paediatric

dietitian as inequality in paediatric dietetic service provision.

CHOOSING AN APPROPRIATE COWS’ MILK PROTEIN ALTERNATIVE MILK

The NICE guideline (8) recommends that a HCP with the appropriate competencies takes an allergy-focus clinical history in order to find/exclude a food allergy diagnose, which may lead to a formula initiation.

This guideline also advises that a dietitian should be involved in the care of children suffering from food allergies and, therefore, in monitoring/advising the type, quantity and length of cows’ milk allergy specialist formula usage in combination with breast milk or as a replacement when breast milk is not available, as well as an appropriate diet.

The following cows’ milk allergy specialist formulae options are currently available in the UK (9):

paediatric food allergy Extensively Hydrolysed formulae (EHF) About 90 percent of children suffering from IgE mediated CMPA (10) and 70 percent presenting non-IgE mediated CMPA (11) will achieve symptoms resolution with an EHF. Although the majority of infants will tolerate all EHF types, it is important to note that some with more severe presentations of CMPA may not and therefore need an AAF. Also the presence of lactose will improve the palatability of the EHF (2).

Amino Acid formulae (AAF) Option for severe CMPA allergic symptoms when exclusively breastfed, severe forms of non-IgEmediated CMPA (e.g. eosinophilic eosophagitis), CMPA combined with faltering growth, reacting to EHF (2). Choosing an AAF when not indicated increases the cost burden on managing CMPA and may affect development of tolerance (albeit the data is very preliminary at this time) (13).

Alternatively consider referral to a paediatric dietitian for assessment prior to prescribing or setting a repeat prescription SUGGESTIONS TO IMPROVE APPROPRIATE PRESCRIBING PRACTICE

Understand local spend data and then create initiatives to target local issues.

With local acute and community agreement produce local guidelines on infant formula prescribing aiming to educate local GPs and other HCPs on the appropriate options to prescribe, as well as the appropriate quantities and length of usage, as well as when and where to refer for specialist review.

Increase awareness of cows’ milk allergy specialist formulae range and prices in HCPs that may be initiating a prescription; updates can be accessed on the London Procurement Partnership (LPP) website (www.lpp.nhs.uk).

Improve your own prescribing practice: • Ensure best practice based on CMPA current guidelines to prevent CMPA misdiagnosis and, therefore, inappropriate usage of the specialist formulae, e.g. encourage regular formula reintroduction after period of cows’ milk protein exclusion to confirm diagnosis of CMPA (8).

• Review prescriptions needs - review patients regularly advising on the most appropriate options. Consider over-the-counter milk alternatives enriched with calcium for patients over one year of age when under the close guidance of a dietitian as deficit in energy, protein, riboflavin, vitamin A and D and fatty acids are likely without adequate dietary sources (2).

• Good communication - ensure correspondences to GPs are complete and clear in regards the formula prescription request to prevent unnecessary prolonged/excessive usage. Inform GPs that soya formula can be purchased by patients.

• Be aware of the MAP and BSACI guidelines providing clear information on the diagnosis and management of CMPA. Cows’ milk allergy specialist formulae appropriate prescribing in a nutshell

Maternal PKU

Phenylketonuria (PKU) was first discovered in 1934 by a Norwegian biochemist and medical doctor called Dr Asbørg Følling (1). In 1957, Prof Charles Dent reported three children (without PKU) of mothers with PKU, all of whom had significant brain damage (2), but it was not until much later that the ‘maternal PKU syndrome’ was properly recognised, described and treated with a low phenylalanine diet for the mother with PKU in order to protect her developing foetus from the teratogenic effects of raised blood phenylalanine levels.

History of maternal PKU

In 1980, Lenke and Levy (3) published an international survey that included data on 524 pregnancies in 155 women with PKU. They reported that in women with PKU untreated during their pregnancy, 92 percent of the babies had mental retardation, 73 percent had microcephaly, 12 percent had congenital heart disease and 40 percent had low birth weights (3).

The Lenke and Levy survey (3) paved the way for a prospective study of the treatment and its benefits, called the International Maternal PKU Collaborative Study (4). This study of 574 pregnancies in 382 women with PKU, demonstrated that intervention with a phenylalanine-restricted diet reduces

microcephaly, intrauterine growth retardation, congenital heart disease and mental retardation in the offspring of PKU mothers (4).

These results are illustrated in the original graph below from the Koch et al paper (4). McCarthy general cognitive index (MGCI) scores are shown for offspring at four years of age, grouped by weeks of gestation after which maternal blood Phe was consistently below 600μmol/L. Graph 1 illustrates the relationship between the timing of dietary intervention and the outcome of the offspring.

The earlier the Phe-restricted diet is started, the better the outcome for the child. The ideal situation is to start the diet before conception, as children

Children of mothers with mild hyperphenylalaninaemia (MHPA) also have a similar outcome as Phe levels are controlled even without treatment. The offspring of women who started the Phe-restricted diet the latest (>20 weeks gestation) had the worst outcome with a MGCI of 70 at four years of age.

From this study, the US researchers recommended blood phenylalanine levels during pregnancy of 120-360Îźmol/L. In the UK, we tend to be slightly more conservative and use phenylalanine levels of 100-250Îźmol/L during pregnancy, possibly up to 300Îźmol/L in some UK metabolic centres.

NHDmag.com July 2015 - Issue 106

The first challenge during the preconception period is to understand the use of 50mg phenylalanine (phe) exchanges (1.0g protein), which must be accurately weighed and counted each day. Where the phe content of a food is not known, 1.0g protein exchanges are used and an understanding of food labelling will be needed to enable this to be calculated. For the many women who are not following a phe- restricted diet, this can prove difficult to understand at first as significant dietary changes will be needed and they may be unfamiliar with the concept of exchanges.

All women are encouraged to bring their partner or a relative to the education sessions for support, as this will be invaluable to help manage the diet at home. The format and number of education sessions is tailored to the individual and home visits may be required in addition to the monthly hospital visit.

Cooking skills are essential when following a phe-restricted diet and this may need to be part of the education sessions. All the companies who manufacture low protein foods have excellent recipe books that give ideas and tips for the use of their products. The tolerance of the phe-free amino acid supplements, e.g. PKU Cooler, PKU Lophlex LQ, can prove problematic due to the unfamiliar taste and, in some cases, abdominal symptoms have been reported. These are essential to meet daily protein, vitamin and mineral requirements and dietary restriction cannot commence until these are established.

When phe control is sub-optimal in childhood, it can cause mild learning difficulties and the level of support required will be significantly increased. During preconception it is essential to control body weight as rapid weight loss can cause an unwanted rise in blood phe levels, which must be corrected as soon as possible, and further weight loss prevented. This is more likely in women who usually follow an unrestricted diet, as the low phe diet is less energy dense than their usual diet. Including a wide variety of low protein foods in the diet will help prevent this, although in some cases further energy supplementation may be required.

pku

During the early stages of pregnancy, related nausea and vomiting can be problematic and can lead to reduced intake or absorption of the amino acid supplements.

Monitoring of blood phe levels is done by dried blood spot, which the women send from home directly to the laboratory twice weekly.

These results are phoned or emailed to the patient as soon as they become available and advice is given if dietary changes are necessary. A minimum of four consecutive levels within the target range of 100-250Âľmol/l is required at Salford Royal Hospital before contraception can be discontinued. These phe levels need to be maintained throughout pregnancy for optimal outcome for mother and baby. Women need to be made aware that, although PKU does not obviously affect fertility, the length of time taken to conceive varies greatly and the low phe diet may be required for many weeks or months prior to pregnancy as well as during.

During the early stages of pregnancy, related nausea and vomiting can be problematic and can lead to reduced intake or absorption of the amino acid supplements. Accurate reporting of the quantity of supplement managed daily is essential and strategies, such as taking smaller more frequent amounts of supplement, often help. The Metabolic dietitian will carefully monitor phe levels to ensure these remain as optimal as possible. In some cases, medication can be used, or in severe cases, hospital admission may be required. At the start of pregnancy, the number of phe exchanges is usually low; in classical PKU this can be as few as two to five exchanges per day (2.0-5.0g natural protein). However, after approximately 20 weeks, these tend to increase as the demand for protein from the foetus increases and by the end of pregnancy some women can be on as many as 25 to 30 exchanges (25-30g natural protein).

In women who usually follow a low phe diet, increasing the number of daily exchanges can prove challenging when only carbohydrate

based foods are used for phe exchanges. The use of a high protein exchange list can help, using small quantities of High Biological Value protein e.g. one egg = six exchanges. The amino acid supplement intake is reviewed by the dietitian as natural protein intake increases and may be gradually reduced to maintain a steady total protein intake.

The Metabolic Team will liaise with the local obstetrician who may decide that additional growth scans would be beneficial. If phe control is good, these are not essential and not all maternity units carry these out. PKU does not carry any additional risks to the mother or baby during delivery. Post-partum, some women choose to remain on a phe-restricted diet, in which case the daily phe exchanges will need to be adjusted to control blood levels to approximately 700Âľmol/l. This is recommended if future pregnancies are desired and current advice in the UK recommends diet for life in all PKU patients. If returning to an unrestricted diet, the nutritional adequacy of this is essential and daily protein requirements must be met. If this is problematic, a small dose of amino acid supplement is recommended by the Metabolic dietitian at Salford Royal.

Case study Nicola age 34 years old follows a relatively strict low phenylalanine diet (12 exchanges). She was initially worried about whether she could manage the diet and whether the baby would be OK. With reassurance and support from the dietitians, she commenced a preconception diet on only two exchanges. Weight loss in her first pregnancy resulted in the need to use extra NHDmag.com July 2015 - Issue 106

artificial calories, as her diet was limited. Nicola found recording exchanges and the PKU Coolers helped; she also noted her phe levels and any changes in exchanges. During her first pregnancy, Nicola struggled with being hungry, not eating enough and when to take the PKU Coolers. Good phe control was managed throughout the pregnancy and a healthy baby boy was born.

During her second pregnancy, Nicola included more low protein foods in her diet and did not require any artificial calories. Any nausea was overcome by snacking and Nicola found that taking the PKU Coolers at the same time as her meals helped with controlling her phe results. Good phe control was managed throughout the pregnancy and a healthy baby girl was born on her older brother’s third birthday.

“For the time you are on the diet, it does take over your life and it is a struggle, but you can do it because you want to. It’s all about planning your diet, using the low protein foods, getting family involved, be it support or making food for you just take it seriously and stick at it ...it’s all very worthwhile.”

What about the baby and PKU?

The baby of a mother with PKU will inherit one copy of the mother’s PKU gene, but this does not

mean that the baby will have PKU. The father of the child needs to be a carrier of the PKU gene in order to ‘pass on’ another copy of the PKU gene, as two copies are required to result in a child with PKU. There is approximately a one in 100 chance of this happening, as the carrier rate for PKU in the UK is one in 50 and there is a one in two chance of the baby inheriting the father’s copy of the PKU gene.

In summary, approximately one percent of babies born to PKU mothers have PKU themselves.

When the baby is born, he/she will be screened for PKU in the same way that all newborn babies in the UK are screened, with the heel prick test taken on day five to eight of life. The heel prick test is not only to detect PKU but other inherited conditions too.

Conclusion

Managing a PKU pregnancy is both challenging and rewarding for the Metabolic team and the patient involved. It requires focused education and intense support from the Metabolic dietitian as well as motivation and determination from the woman with PKU and her family. With the right support in place, both mother and baby can achieve a healthy outcome.

Ketogenic diet

Ketogenic therapy for adults with drug resistant epilepsy: time it was on the menu for adults

Susan Wood Specialist Dietitian, Ketogenic Therapies Matthewâ&#x20AC;&#x2122;s Friends Clinics and Charity

Susan works full time for Matthewâ&#x20AC;&#x2122;s Friends Clinics and Charity as a Specialist Ketogenic Dietitian, treating children and adults with drug resistant epilepsy and adults with brain tumours.

28

Despite the best efforts of modern anticonvulsant medicines and the availability of novel approaches, such as vagal nerve stimulation and epilepsy surgery, around 30 percent of children and adults are refractory to treatment, enduring a life of poor seizure control and impaired quality of life.

The ketogenic diet (KD) has been used as a treatment for epilepsy since the 1920s, pre-dating most anticonvulsant drugs.

It evolved from the knowledge that extended fasting readily led to a significant seizure improvement and that this effect could be replicated by altering the macronutrient profile of the diet, triggering a metabolic shift away from carbohydrate to fat as the predominant dietary energy source.

It was not until 2008 that the first randomised controlled trial (RCT) of KDs in children was published by a pioneering team from Great Ormond Street Hospital, proving efficacy equivalent to modern anticonvulsant drugs and endorsing the use by specialist paediatric teams across the world (1).

The first and largest ever study of KDs in adults (n=81) was published in America in 1930 (2), but despite positive results (over half achieved a 50 percent or greater reduction in seizures) and further small trials over the decades, they continue to be rarely used within the adult epilepsy world.

A recent meta-analysis of 12 relevant adult trials (270 adults) reported efficacy in 42 percent of cases, suggesting parity with paediatric trials (3).

Almost half of these studies used a modified Atkins diet (MAD); a more liberal approach first used in children in 2003 (4), making treatment a more practical possibility for adults and children alike. A UK adult trial is in the early planning stages and results from a Norwegian RCT started in 2011 are eagerly awaited (5).

How does a ketogenic diet work?

(See Figure 1). Carbohydrate reduction, the cornerstone of ketogenic diets, reduces glucose availability and the stimulus for insulin secretion. This triggers an increase in the rate of fatty acid oxidation in the liver and the release of

Ketogenic diet ketones into the circulation. Brain tissue rapidly adapts to this altered state, using ketones as the primary fuel to drive energy metabolism. The exact mechanisms by which a ketogenic diet exerts its anticonvulsant effect are likely varied and as yet unconfirmed, but it is thought that it enhances brain energy reserves, stabilising neuronal tissue and influences the balance of neurotransmitters and a range of compounds involved in exciting and inhibiting electrical activity within brain tissue (6).

What does a ketogenic meal look like?

Three meals providing 6gCHO & 60g Fat:

What changes can it deliver?

Ketogenic therapy can deliver a significant reduction in seizure frequency, intensity and reduce the time needed to recover from seizures.

Adult responders often report more subjective changes, such as being able to think more clearly, concentrate better, have more energy and feel generally brighter in mood (7). Overweight individuals successfully lose weight, reporting positive changes in body shape; particularly waist circumference. These changes readily occur within the first three months of KD treatment, despite there being no change in the anticonvulsant doses. Considering that those referred into ketogenic therapy may have failed for decades to gain adequate seizure symptom control from all available medications, you may appreciate how exciting it is to the patient, the carers and the ketogenic team, when it delivers a life-changing response.

The diet prescription

All ketogenic regimes are designed around the nutritional requirements of the individual and are low in carbohydrate, high in fat and provide adequate protein. Traditional ketogenic approaches require weighing of all food items so that ratios (the Classical KD) or percentages (the Medium Chain Triglyceride KD) of fat protein and carbohydrate are maintained consistently in all meals and snacks. However, for the majority of UK adults, we use a more liberal modified ketogenic approach based on the Modified Atkins Diet (MAD) devised by the team at Johns Hopkins Hospital (8).

The basic essentials of a Modified Ketogenic Diet used at Matthewâ&#x20AC;&#x2122;s Friends Clinics are as follows:

Ketogenic diet • Carbohydrate is restricted to 5.0-10g per meal and 2.0-3.0g in snacks (a total of 20-30g per day) and is always accompanied by fat.

A 1.0g carbohydrate exchange system is used and foods are weighed on gram scales. Typical carbohydrate sources are non-starchy vegetables, fruits (mainly berries), nuts, seeds and double cream.

• Fat must always be consumed alongside

any carbohydrate containing food. Portion guidance is based on a 10g exchange system and designed to meet individual calorie requirements. For example a 2,000kcal regime will likely require a minimum of 170g fat. Typical fat sources are olive oil, butter, double cream and mayonnaise, with supplementary amounts provided from dietary protein sources.

Figure 2: Treatment criteria and treatment stages Criteria for ketogenic therapy in adults The adult will have failed to respond to at least two anticonvulsant medications and be keen to explore the KD. Medical contraindications (biochemical screening is essential): • Fatty acid oxidation defects, organic acidurias, pyruvate carboxylase deficiency, any disorders requiring a high carbohydrate treatment.

• A history of familial hyperlipidaemia, renal stones or eating disorders.

• Pregnancy or planning pregnancy.

• Proceed with caution and optimise management before initiating KD therapy: dysphagia, gastrooesophageal reflux, chronic constipation or diabetes.

Summary of treatment stages Pre-KD diet assessment appointment; neurologist and dietitian • Review of epilepsy history, medical management and all relevant tests including biochemical screening.

• Discussion of the practical issues (the food, importance of monitoring), possible negative side effects (mainly lethargy during initial week of transition and constipation. Increased risk of renal stones and osteoporosis long term) and possible outcomes.

• Timing of the treatment to enable commitment to three months with no planned interruptions.

KD treatment education session; dietitian and ketogenic diet assistant • • • • •

KD prescription based on BMI, activity levels, estimated energy requirements and whether weight maintenance or loss are desired.

Guidance on sources of protein CHO and fat.

Practical menu guidance based on food preferences and lifestyle.

Guidance on monitoring: blood ketone (1.0-5.0mmol/l) and glucose testing or urine ketone testing as appropriate, seizure, symptom and weight monitoring.

Guidance on vitamin and mineral supplementation; in most cases, a one-a-day adult multivitamin and mineral, plus additional calcium and vitamin D.

Follow up; dietitian and ketogenic diet assistant • •

Regular contact by phone/email; generally once or twice a week until a level of stability is reached.

Adjust diet prescription as required, based on seizure symptoms, weight and blood or urine ketones.

Three-month follow up; neurologist and dietitian • Repeat blood biochemistry.

• If no change in seizure pattern or any related parameters (energy levels, alertness, clarity of mind, seizure recovery time etc), consider weaning back towards mainstream low GL diet.

• If proving beneficial, continue treatment and review in a further three months and thereafter six monthly.

At two years, discuss the possibility of weaning back towards a more mainstream low GL diet regime.

However, if it is working well for them, adults are reluctant to make significant changes.

Ketogenic diet

Adults seeking advice from their neurology teams are readily told that ketogenic therapy is too complex, unpleasant, unhealthy and only effective in children. â&#x20AC;˘ Protein is consumed with each meal and in normal portions (a therapeutic ketogenic diet is not a high protein diet). Typical protein sources are eggs, poultry, red meat, fish, cheese, nuts and seeds.

Enteral feeds are normally based on the Classical KD, with ketogenic ratios for adults (perhaps 2:1 to 3:1) generally lower than those used in children, due to larger protein requirements. As there are no commercially available adult KD formulae, feeds tend to be based around the paediatric product Ketocal (Nutricia), available in liquid or powdered form and designed for children aged one to 10 years. It always requires adjustment with additional protein, carbohydrate, vitamins and minerals when used for adults. See Figure 2 for treatment criteria and treatment stages.

Current barriers to adult treatment

Adults seeking advice from their neurology teams are readily told that ketogenic therapy is too complex, unpleasant, unhealthy and only effective in children. This is due to a lack of knowledge and experience in the practicalities of modern day ketogenic therapy within the adult neurology and dietetic sector and the lack of RCT evidence to enable NHS service developments for adults.

The high fat intake required by KDs raises concerns in uninitiated healthcare professionals and patients alike. All treatment protocols involve elements of energy prescription to deliver precise control of body weight and the full lipid profile is measured at baseline, then three to six monthly onwards as part of the biochemical monitoring. The KD prescription is adjusted as often as required to optimise outcomes and, where necessary, steps can be taken to influence lipid fractions by altering dietary fat sources. A study in adults on a MAD KD for three months or longer, reported that the increased levels of total cholesterol 32

NHDmag.com July 2015 - Issue 106

and LDL found in the first three months, normalised within 12 months.

No cardiovascular or cerebrovascular incidents were reported in 12 adults followed for three or more years (9). Over recent years, there has been increasing interest in the potential value of low carbohydrate regimes in the management of obesity, Type 2 diabetes and metabolic syndrome, in terms of weight loss, increased serum high density lipoprotein cholesterol, increased low density lipoprotein particle size, reduced serum triglyceride levels and improved sensitivity to insulin (10, 11). It is possible that the flatter glucose/insulin profiles and the metabolic shift from fat storage towards fat oxidation induced by the KD may convey additional metabolic benefits to some adults with refractory epilepsy.

In 30 years of clinical practice, I havenâ&#x20AC;&#x2122;t encountered a more powerful and life transforming dietary treatment than ketogenic therapy. Frustratingly, we are still unclear about the mechanisms of action and have no way of predicting who will respond and who will not. With the current limitations on the provision of ketogenic services, this knowledge would be immensely helpful. However, the potential of ketogenic diets to bring hope and a sense of control to individuals who have neither, is a powerful driver to those patients and clinical specialists in pursuit of increased availability of this century-old therapy that modern medicine cannot yet find a way to replace.

In the UK, ketogenic therapy for adults with epilepsy is provided through Matthewâ&#x20AC;&#x2122;s Friends Clinics (www.mfclinics.com), the adult metabolic team at the National Hospital for Neurology & Neurosurgery in London and a neuropsychiatry team at The Barberry in Birmingham, with some single case provision in other centres.

For further information on ketogenic therapy including adult protocols, please see reference 12.

Ketogenic diet

“Within a few weeks of starting the ketogenic diet, the intensity and frequency of my seizures decreased . . .”

Case study: Andy, aged 50, has seizures as a result of a brain tumour.

He has been using a modified KD for three and a half years.

“I have tried a variety of different anticonvulsant drugs with varying degrees of success and failure. Some of the drugs have me made me short tempered; some of them have made me fixate on small, insignificant issues, others have just not controlled the seizures enough and I have wound up back in hospital. And all of them give me fatigue and I find this the hardest to deal with.

“Within a few weeks of starting the ketogenic diet, the intensity and frequency of my seizures decreased and, with the guidance of my neurologist, I was able to gradually taper my Clobazam dose and withdraw it completely eight months after commencing ketogenic therapy. This has resulted in a significant improvement in my concentration and overall energy levels with no worsening of the seizures. It has given me a huge chunk of my life back.”

Liver disease

Weight gain and obesity after liver transplantation Obesity in post liver transplant patients is an increasing problem which is under recognised with no definite guidelines for surveillance or treatment.

Susie Hamlin Senior Specialist Hepatology, Liver Transplant/ ICU Dietitian, Leeds Teaching Hospitals NHS Trust

Julie Leaper Senior Specialist Hepatology, Liver Transplant/ ICU Dietitian, Leeds Teaching Hospitals NHS Trust

Susie and Julie work in hepatology and liver transplantation, providing nutritional advice to patients with complex nutritional issues.

They are joint clinical liver leads for the gastroenterology specialist group of the British Dietetic Association.

Sixty-seven percent of men and 57 percent of women in the UK are overweight or obese from data that uses a Body Mass Index (BMI) of over 25kg/ m2 to define overweight and a BMI over 30kg/m2 or more to define obese (1).

The incidence of post liver transplant (LTX) obesity is suspected to be higher than the UK population figure. As the incidence of overweight and obesity rises in the general population, more people than before become ill with liver diseases with a BMI higher than seen in previous decades (2).Obesity also accelerates the progression of liver cirrhosis in patients with Hepatitis C and alcohol related liver disease (ARLD) (3).

Most significantly, there is a rising epidemic of patients presenting for LTX assessments with non-alcoholic fatty liver disease (NAFLD), which is considered the hepatic manifestation of metabolic syndrome and directly linked to obesity and being overweight (4). NAFLD is defined as the presence of >five percent deposition of triglycerides in the liver in the absence of significant alcohol consumption. This results in a liver injury similar to the hepatic injury seen in ARLD. The stages of disease progression are the same as ARLD in that they range from simple steatosis, fibrosis to non-alcoholic steatohepatitis (NASH) and finally cirrhosis (5, 6). As NAFLD is directly linked to Metabolic Syndrome (MS), being overweight and obesity, more patients with NAFLD present for LTX assessment with additional risk factors for cardiovascular disease.

A recent analysis of the Scientific Registry of Transplant Recipients in the USA confirmed that NASH, as an indi-

cation for LTX, increased over sevenfold from 2001 to 2009, while no other indication for liver transplantation increased over the same time period (7).

In the UK and western societies, with rising rates of obesity, a similar clinical picture is predicted in the coming years.

NAFLD is now the third most common indication for LTX and is predicted to surpass Hepatitis C and alcohol as the leading indication for LTX in the near future due to the increase in features of metabolic syndrome (8). This is important as obesity affects outcome both at the time of transplant and in the longer term (9). The United States United Network for Organ Sharing (UNOS) database examined the outcomes of 29,000 LTX patients which showed higher early and late mortality, mostly as a result of adverse cardiovascular events in overweight and obese patients (10).

Some weight gain after LTX is inevitable, as most cirrhotic patients on a waiting list for LTX display characteristics of protein energy malnutrition, regardless of their underlying disease or diagnosis of NASH, cirrhosis and presence of obesity. Muscle wasting is apparent, despite dry BMI being >25kg/m2 due the severe metabolic changes that occur in cirrhosis (11). These patients recover their nutritional status, but seem to achieve a higher weight than pre-transplant, which increases the prevalence of overweight and obesity after LTX (12, 13).

The reasons for weight gain are multifactorial. Having undergone a transplant, patients feel better, appetite improves, taste changes resolve, abdominal distension and early satiety from ascites resolve, metabolism returns to a non-catabolic NHDmag.com July 2015 - Issue 106

35

liver disease state, patients can relax pre-transplant dietary restriction and functional ability is improved. Dietetic therapy in the first three months post-transplant aims to recover nutritional status and, during the initial three months post-transplant, this is the time corticosteroids are often prescribed which aids appetite and can promote weight gain.

Rezende et al (14) examined weight changes and incidence of excessive weight up to three years post LTX. The incidence of excessive weight (BMI ≥25kg/m2) and obesity (BMI ≥30kg/m2) was measured before LTX and at year one, two and three post LTX. The results demonstrated a significant number of patients who were overweight or obese one, two and three years after LTX and who were also overweight before having liver disease (p <0.01), but the percentage of patients with excessive weight (BMI >25kg/m2) was higher within two (51.3%) and three years (56.3%) after surgery than before liver disease (49.4%).

These studies support the need for weight loss strategies in patients post LTX which should be considered during the three to six months postoperative period following initial rehabilitation.

As life expectancy of post LTX patients increases, the problems associated with excessive weight gain rise too, including greater incidence of post transplant metabolic syndrome (PTMS) and cardiovascular events post LTX (8). NAFLD and NASH can reoccur in patients post LTX and the risks of it developing are directly linked to post-transplant overweight and obesity, female sex, Type 2 diabetes or family history of Type 2 diabetes and development of PTMS (15). PTMS has an estimated prevalence of 44 to 58 percent in LTX recipients and is associated with increased cardiovascular mortality (16). Weight loss in overweight obese patients post LTX with concurrent medical treatment of each element of PTMS has benefits both in term of cardiovascular and liver outcomes (17). Evaluation of the weight gain after LTX is necessary to identify overweight and obesity and propose strategies to prevent and treat as the extent and consequences of this condition are becoming increasingly well recognised.

Three key interventions that have been shown to be effective in weight loss management are: 1 weight loss via dietary means 2 bariatric surgery 3 Orlistat use 36

NHDmag.com July 2015 - Issue 106

Dietary intervention

Guidelines produced by the American Gastroenterological Association (2002) following a systematic review of the evidence at that time stated that: • those who are overweight (body mass index >25kg/m2) and have NAFLD should be considered for a weight loss program; • a target of 10 percent of baseline initial weight should be the goal of weight loss; • weight loss should proceed at a rate of one to two lb/wk; • exercise 30 to 60 minutes daily is recommended (daily exercise can help achieve weight loss and improve insulin sensitivity); • those with a body mass index of >35kg/m2 and NAFLD can be considered for more aggressive weight management, including a gastric bypass.

A more recent review by NICE in 2011 (18) concluded that: ‘Weight reduction with different measures for treating NAFLD is recommended.’

Other cohort studies looking at NAFLD have observed a beneficial effect in ALT and cardiovascular outcomes with five to 10 percent weight loss initially, then aiming for 0.5-1.0Kg/week (19).

Studies have also reported beneficial results with weight loss on NASH by lowering body weight and increasing physical activity (20). Another study showed weight loss of at least three to five percent appeared to be necessary to improve steatosis, but greater loss of up to 10 percent may be needed to improve necroinflammation (19).

A randomised control trial by Promrat et al (21) examined the effects of lifestyle intervention (LI) using diet, exercise and behaviour modification, with a goal of seven percent to 10 percent weight reduction on the clinical parameters of NASH. Patients were randomised to a lifestyle intervention and received an intensive weight loss program based on the Diabetes Prevention Program ‘Look AHEAD’, used in the USA for Type 2 diabetes with successful outcomes, or structured education provided by a health professional in large groups every 12 weeks (control) (22). After 48 weeks of intervention patients in the LI group lost an average of 9.3% of their weight versus 0.2% in the control group (p=0.003).

Patients who achieved a weight loss goal (>7.0%) compared with those who lost less than

liver disease 7.0% had significant improvements in steatosis (-1.36 versus -0.41 p<0.001) and Nash Activity Score (-3.45 versus -1.18 p <0.001). This study adds strong evidence that weight loss and exercise improve histological liver features in patients with NASH and, therefore, could be an appropriate treatment in NAFLD/NASH recurrence in LTX patients.

There appears to be a clear benefit in five to 10 percent weight loss in NAFLD and seven percent weight loss in NASH. Achieving this weight loss is a challenge in clinical practice. The level of intensity of treatment to reduce weight by five to 10 percent would require access to weight management services in local areas. NICE Guidance 53 (23) gives a framework for the provision of obesity services and there has recently been a change in commissioning for Tier 2 obesity services to local authorities. There is likely to be large discrepancies in the availability of Tier 2 and 3 services in different areas.

Bariatric surgery post LTX

Bariatric surgery is known to improve metabolic profiles in non-transplant patients and this may be beneficial in preventing recurrence or development of NAFLD post LTX (24). There is a small number of case reports published that describe bariatric surgery post LTX. As yet, it is not clear how and when to consider bariatric surgery and the type of bariatric operation to do in this group.

Procedures that induce malabsorption, such as Roux En Y bypass and duodenal switch, are likely to result in difficulties with the management of immunosuppression levels. This problem could be avoided with bariatric surgeries that restrict volume consumed, such as gastric band and sleeve gastrectomy, as this would have very little influence on the absorption of immunosuppression medications. Lin et al (25) and Butte et al (26) both described case reports with sleeve gastrectomy post LTX. Another case report by Campsen et al (27) describes a gastric band placement at the time of LTX which reported good outcomes and weight reduction from BMI 42 kg/m2 to 34kg/ m2 within six months of surgery.

There is evidence that outcomes at BMI +40kg/m2 at time of transplant are poor and some LTX centres use BMI greater than 40kg/m2 as an excluding factor from liver transplantation (28).

However, it is highly likely that, as the number of patients with overweight and obesity having liver transplants for NAFLD and other conditions increases and the predicted post transplant weight gain occurs (29), there will be more patients presenting with BMI +35kg/m2 with co-morbidities or BMI =40kg/m2 post LTX who will be eligible to access Tier 4 bariatric services.

The role of Orlistat

Historically, Orlistat was not considered suitable for LTX recipients because it was thought to interfere with the absorption and resulting suboptimal serum levels of immunosuppression drugs Tacrolimus and Cyclosporine. With the rising incidence of obesity post LTX, the use of Orlistat is being reconsidered.

In a meta analysis of 16 clinical trials by Rucker et al (30), Orlistat reduced weight by 2.9kg (95 percent confidence interval 2.5kg to 3.2kg). Another small cohort study (N=15) by Cassiman et al (31) described the safe short-term use of Orlistat in a post-transplant group of patients on tacrolimus. The patients were advised to take tacrolimus separately from meals, one hour before the meal, NHDmag.com July 2015 - Issue 106

37

liver disease or more than two hours after. Orlistat was taken half an hour before meals and target tacrolimus levels were achieved throughout the study.

This study was the first to show that immunosuppression could remain within therapeutic levels whilst taking Orlistat. This area needs further research and development of clear guidelines on proposed Orlistat use in post LTX patients. It would be imperative that patients could access their local Tier 3 obesity services if they met the referral criteria of BMI +35kg/m2 with significant co morbidities or BMI +40kg/m2 in line with NHS England. Guidance on timing of immunosuppression medication and frequent blood tests would be required during the treatment period.

Conclusion

The barriers to providing obesity-centred initiatives in post liver transplant patients lie in the lack of recognition of prevalence and clear treatment pathways for this group of patients. There are no

local, regional or national initiatives specifically for this group of patients despite the long-term increased cardiovascular risk and clear benefit of weight loss programs which can achieve five to 10 percent weight loss. The development of treatment pathways to identify obese and overweight patients and develop referral criteria within the first six months post operatively to signpost patients to appropriate Tier 1-4 obesity services in their local areas, is underway .Leeds Teaching Hospitals NHS Trust liver unit covers a population of approximately seven million which crosses several local authorities providing Tier 1 and 2 services and clinical commissioning groups that provide Tier 3 and 4 services. The inequality will lie in what services are offered in different areas as weight loss programs cannot be supported by regional liver units.

Obesity surgery

Bariatric surgery and the importance of nutrition The prevalence of obesity in the UK continues to rise and is associated with many health issues such as diabetes, metabolic syndrome, obstructive sleep apnoea and osteoarthritis. The focus of treatment is on dietary, activity and lifestyle changes; however, for those with severe and complex obesity, bariatric surgery may be a treatment option.

Mary Oâ&#x20AC;&#x2122;Kane Consultant Dietitian (Adult Obesity), Leeds Teaching Hospitals NHS Trust

The main bariatric surgical procedures are the gastric band, gastric bypass and sleeve gastrectomy (Figures 1-4).

The duodenal switch is performed less frequently. All procedures affect the dietary intake and the gastric bypass, sleeve gastrectomy and duodenal switch affect absorption to varying degrees. For patients with severe and complex obesity, bariatric surgery is an additional tool which will aid weight loss and result in metabolic improvements. The National and Bariatric Surgery Registry (NBSR) reported that the average weight loss at one year after surgery was 58.4% excess weight (1). Two years after surgery, 65 percent of patients with Type 2 diabetes were able to stop their medication.

Eligibility for bariatric surgery

Mary is a Consultant dietitian supporting patients with severe and complex obesity in the medical and surgical obesity pathways.

Member of BOMSS council.

Member of NICE clinical guidelines Obesity 2006 and 2014.

To be eligible for bariatric surgery, a number of criteria must be met (National Institute for Health and Care Excellence (NICE) 2014 (Table 1) (2). In the NHS, patients are referred in for surgery by the Tier 3 medical obesity services. The patient will undergo a comprehensive multidisciplinary team (MDT) assessment which includes exploring the benefits and risks of surgery. The dietitian plays a key role in the assessment of the patientâ&#x20AC;&#x2122;s understanding of bariatric surgery and ability to comply with postoperative dietary advice and cope with the emotional impact. Not all patients will go forward for surgery as the team may consider some patients to be too high risk or recommend further investigation and treatment. Other patients will de-

cide that surgery is not for them or that the timing is not appropriate.

Impact on diet and nutrition

All of the surgical procedures impact on dietary and nutritional intake (Table 2).

The gastric bypass, sleeve gastrectomy and duodenal switch procedures affect the absorption of micro and macronutrients to varying degrees. The specialist bariatric dietitian plays an important role is supporting patients through their weight loss journeys and ensuring nutritional needs are met.

Following surgery, all patients are advised to progress their diet slowly, beginning with a liquid diet before moving onto blended food, soft food and then foods of a more normal texture. They must learn to chew their food well, eat slowly and avoid having drinks with meals. Certain textures of food are difficult to manage for example, roast or grilled meats and poultry, bread, rice and pasta. These can be replaced with casseroled meats and poultry, crisp breads, crackers and toasted bread and potatoes. The initial portion sizes are very small, but will increase over time. Patients need support to make the dietary changes including the planning of meals. Some patients may struggle to follow the advice. If they try foods of an inappropriate texture or do not chew their food, they may find it becomes lodged in the gastric pouch causing pain and discomfort. This may then lead to food avoidance /phobias or replacement with soft high calorie foods NHDmag.com July 2015 - Issue 106

Obesity surgery and a diet of poor quality (3). Unfortunately, soft and crispy textured foods such as crisps, biscuits, cakes and ice cream are easy to consume.

In addition, the sleeve gastrectomy, gastric bypass and duodenal switch affect absorption.

For all of these procedures, the absorption of calcium, vitamin D, vitamin B12, zinc, copper and selenium may be reduced (4, 5). The duodenal switch also impacts on the absorption of fat, protein and fat soluble vitamins and so carries additional risks. Consequently patients are advised to take additional multivitamin and mineral supplements.

NCEPOD

The National Enquiry into Patient Outcome and Death 2012 report ‘Too Lean a Service’ reviewed the bariatric patient journey from referral to postsurgical follow up and made a number of recommendations (6). In the report’s foreword, Bertie Leigh, NCEPOD chairman, said, “If changes in eating behaviour are to be sustained, the advice of the dietitian will be invaluable. If surgery is to be sufficiently radical to resolve problems of extreme obesity in isolation, the dangers of malnutrition cannot be avoided with confidence.”

Recommendations included access to good quality postoperative dietary advice and a continuous long-term follow up plan.

BOMSS survey

A survey of current practice of British Obesity and Metabolic Surgery Society (BOMSS) members with respect to nutritional assessment and monitoring of patients undergoing bariatric surgery was undertaken in 2012 (7). This showed that whilst there were areas of good practice, there was also considerable variation. It highlighted variation in nutritional monitoring and the use of vitamin and mineral supplements. Although the American Association of Clinical Endocrinologists, The Obesity Society and American Society for Metabolic and Bariatric Surgery (AACE/ASMBS/TOS) had published guidance (Medical Guidelines for Clinical Practice for the peri-operative Nutritional, Metabolic and Non-surgical Support of the Bariatric Surgery Patient), many centres had found this difficult to implement (4). BOMSS council agreed that UK guidance was needed and a working group

led by Mary O’Kane was formed. Its remit was to develop the first UK guidance on nutritional monitoring and supplementation for patients undergoing bariatric surgery.

BOMSS guidance

As part of the BOMSS survey, relevant literature, including other guidelines, was reviewed (7).

The working group agreed the BOMSS guidance would cover pre-operative assessment, post-operative nutritional monitoring, abnormal results and clinical problems and vitamin and mineral supplementation. A further literature review was undertaken.

Writing the guidelines was a challenge.

Whilst the AACE/ASMBS/TOS guidelines were comprehensive, they were difficult to apply in practice in the UK. There were significant differences in the recommendations around vitamin D in the US and usual practice in the UK. It was agreed that the BOMSS guidelines should be practical and easy to implement and address many of the clinical concerns.

Where there were no clear conclusions from the literature, consensus opinion was reached.

Recommendations were made about pre-operative nutritional assessment, post-operative nutritional monitoring and frequency, vitamin and mineral supplements and clinical problems/abnormal blood results. The draft guidelines went out to wide consultation within BOMSS and there was healthy debate. In addition, the views of endocrinologists were sought, especially concerning vitamin D. The final version ‘BOMSS Guidelines on perioperative and postoperative biochemical monitoring and micronutrient replacement for patients undergoing bariatric surgery’ was launched in October 2014 and is available from the BOMSS website (8). A summary of vitamin and mineral supplementation is given in Table 3, but the guidelines contain the full recommendations on nutritional monitoring and supplementation.

The BOMSS nutritional guidelines have been well received by the bariatric surgery community, GPs and patients and have stimulated debate. for the management of patients post-bariatric surgery in primary care’ (9). As part of this work, a shorter version of the BOMSS guidance was produced for GPs: ‘GP Guidance: Management of nutrition following bariatric surgery’ (10).

NICE Clinical Guidelines 189 Obesity

In the update of the NICE Clinical Guidelines 189 Obesity, the recommendations on longerterm nutritional follow up of bariatric patients were strengthened (2). There is lack of clarity however as to how this will be achieved.

Feedback and next steps

The BOMSS nutritional guidelines have been well received by the bariatric surgery community, GPs and patients and have stimulated debate. They are available on the BOMSS website.

The NHS England Obesity Clinical Reference Group is writing the service specification for the follow up of bariatric surgery patients.

Mary O’Kane is chairing and leading this subgroup and the guidelines will play a key part of this work. Defining the components of the longer-term follow up of these patients is a challenge. Generally, the bariatric centres are only commissioned to provide two years follow up after the bariatric procedure with care returning to the GP. Although the bariatric centre has a responsibility to ensure that there is clear communication at the time of discharge around nutritional monitoring and vitamin and mineral supplementation, there is no robust mechanism for ensuring lifelong nutritional monitoring.

This is stimulating active discussion in the subgroup as to how it is best addressed.

Table 1: NICE criteria for bariatric surgery Bariatric surgery is a treatment option for people with obesity if all of the following criteria are fulfilled: •

They have a BMI of 40kg/m2 or more, or between 35kg/m2 and 40kg/m2 and other significant disease (for example, Type 2 diabetes or high blood pressure) that could be improved if they lost weight.

•

All appropriate non-surgical measures have been tried but the person has not achieved or maintained adequate, clinically beneficial weight loss.

•

The person has been receiving or will receive intensive management in a Tier 3 service.

•

The person is generally fit for anaesthesia and surgery.

•

The person commits to the need for long-term follow up.

Bariatric surgery for people with recent-onset Type 2 diabetes: •

Offer an expedited assessment for bariatric surgery to people with a BMI of 35 or over who have recentonset Type 2 diabetes [12] as long as they are also receiving or will receive assessment in a Tier 3 service (or equivalent).

•

Consider an assessment for bariatric surgery for people with a BMI of 30-34.9 who have recent-onset Type 2 diabetes, as long as they are also receiving or will receive assessment in a Tier 3 service (or equivalent).

•

Consider an assessment for bariatric surgery for people of Asian family origin who have recent-onset Type 2 diabetes at a lower BMI than other populations, as long as they are also receiving or will receive assessment in a Tier 3 service (or equivalent).

Conclusion

Bariatric surgery is an appropriate treatment option for some patients with severe and complex obesity, providing certain criteria are met. It can result in significant weight loss and resolution or improvement in comorbidities. If patients receive the correct advice and support and are compli-

ant, there should be minimal risk of nutritional issues. Long-term nutritional monitoring and compliance with vitamin and mineral supplements are essential components of aftercare. The BOMSS guidelines give clear recommendations which support the care of these patients and may stimulate future research in this area.

Home Enteral Tube Feeding Services

Five years of change: a view from patients and carers An innovative nutritional products contract, awarded in 2007, was the catalyst for significant development of the Home Enteral Tube Feeding (HETF) support for adults and children across Nottinghamshire. Changes made during this period had clear benefits for service provision and costs, but the impact on patients and carers had never been formally reviewed.

Gillian White Dietitian

Five years on seemed a good time to canvas the views of patients and carers made possible by a small Research into Practice Grant from The East Midlands Collaboration for Leadership in Applied Health Research and Care (CLAHRC). Although I had been part of the Nottingham HETF service since 1999 and was involved in many of the changes that had taken place, at the time of the project I had little direct patient contact and would be unknown to the patients and carers.

Background

Gillian has dietetic experience in oncology, palliative care and nutrition support. She held the post of Therapy Services Manager at Nottingham University Hospital, which included leading the development of Nottinghamshireâ&#x20AC;&#x2122;s Home Enteral Tube Feeding Service, until October 2013.

NICE Guidance (2006) recommended a multi-professional team approach for tube-fed patients at home, with individualised care plans, including monitoring and aims, and training for patients and carers to manage tubes, delivery systems, procedures and regimen, recognise risks and troubleshoot common problems.

Routine and emergency contact numbers, information about delivery and regimen, contact details for delivery company and instruction manuals should also be provided. Before 2007, small, separate dietetic teams of one to three staff provided HETF support throughout Nottinghamshire, aiming to meet NICE guidance, but struggling to cope with growing demand and complexity. Since 2007, gradual change has led to the creation of one service based within a single organisation, aiming to provide consistent best practice for all HETF patients within Nottingham and Nottinghamshire.

Combining existing budgets with new funding, specifically for nutritional

products and ancillaries, enabled better use of existing funds (e.g. economy of scale, shared approach), with savings ploughed into service development including staffing. A coordinated service with increased staffing, including specialist nursing and support workers, meant that there was time to provide training for all patients and carers, as well as school and community nurses and care homes.

Commercial partners were monitored more carefully and liaison with partners in hospital and community were strengthened. The overarching direction of change was from inconsistency and a â&#x20AC;&#x2DC;fire fightingâ&#x20AC;&#x2122; approach towards planned and equitable care.

In 2012, Nottinghamshire had a single HETF Service with a team of dietitians and dietetic assistants (18wte cf 5wte in 2007) based together and working to shared guidelines to support adults and children. A locally agreed patient pathway allowed better monitoring of patients and resources, a flexible response to external change and the development of a supportive team approach, including close working relationships with hospital dietitians and other partners. This service change happened in the context of many NHS changes and increasing pressure on funding, with further change being planned to ensure future sustainability.

The project

I carried out a small retrospective survey of home enterally tube-fed patients and their carers who had been in contact with NHDmag.com July 2015 - Issue 106

45

Home Enteral Tube Feeding Services the HETF team since 2007, electing to talk directly to a small number of individuals about their experiences. Of the active 655 patients on the HETF database in May 2012, 159 started home enteral feeding before 2007 (i.e. for the whole of this period), but only 80 of these were living in their own homes with more involvement in feed delivery and care.

From this group, seven patients fully supported by the core HETF team, rather than sharing care with specialist hospital colleagues, were interviewed, representing a cross section of age groups and managed by different members of the team.

Team meeting records and reports, plus discussion with long-standing team members helped identify the variety of changes made since 2007. As well as planned changes linked to the new contract (for example moving to an ‘off script’ system and change of feeding pump in hospital and community), there were wider changes, such as the development of Clinical Commissioning Groups, Trust mergers, responding to national guidance such as NPSA alerts, and practical changes such as moving office, new staff, change of feed and equipment, record keeping and electronic systems. Discussion with the team also helped form an interview schedule with key questions to be used in all the interviews (see Box 1). Interviews started with open exploratory questions about individual experience, then moved on to asking questions about specific changes that we knew had taken place. Interviews usually took place in patients’ homes and were recorded; initial written notes were typed, then reviewed and expanded by listening to the interview recording. The format and outcomes of the project were discussed with a patient representative for more objective feedback about content and clarity, as well as with the CLAHRC team.

Findings

Over 40 changes were identified, including contractual change, feed and equipment, staffing, resources, costs and organisation; but many of these were ‘backroom’ changes supporting team working or systems of care.

None of the patients or carers interviewed recalled the change from prescribed enteral feeds to an ‘off script’ approach, seen by the team as the most significant change in 2007. Indeed, few of the changes listed were highlighted directly, although, with prompting, some people remembered changes 46

NHDmag.com July 2015 - Issue 106

such as feed reformulation or a new type of pump.

Changes to feeding regimen or routine equipment (e.g. syringes) were more memorable depending on impact on the individual.

“As a user I have noticed very little, which is fantastic! There may be massive change behind the scenes, but dietetic services ‘hide’ the change so it doesn’t impact on families which is a real benefit.”

“Changes happen but aren’t noticed. One was the feeding pump; we preferred the old type and kept that, but might not have given it long enough.”

All the patients and carers knew how to contact their dietitian and the HETF service if needed. Relationships with dietitians, who carry out regular face-to-face reviews, were stronger than with assistants, who do telephone reviews and help with ordering and problem solving. Planned regular contact was viewed very positively by all those interviewed, with positive feedback about the feed provider and delivery service confirming their annual patient survey.

The team supports a significant number of patients for more than five years, with trust and confidence building up over time and developing a therapeutic relationship which supports patient care. This is especially important when tube feeding starts in childhood and in the transition from paediatric to adult services, including change of dietitian; these are often all traumatic times.

“Very positive about the impact of feeding.

Since had gastrostomy health improved, no longer back and forward into hospital, chest improved, ‘never looked back’. Initially reluctant but would recommend it to anyone now.”

Early experiences of feeding could be especially traumatic and the interviews reinforced the importance of the team during the first few months of feeding and during periods of change.

“To start with I wanted more contact, lot to learn. Getting used to new dietitian, no contact with assistant yet.”

“It’s really nice to talk outside the hospital environment, face to face, to have time to talk rather than rushing in the hospital. Someone comes into your home and sits opposite you at the table, you talk more, explain how you are doing it at home, talk about problems at home instead of hospital where it’s a different world.”

Good communication was important, with some requests for more explanation of things that

Home Enteral Tube Feeding Services the team may take for granted, such as the role of assistants and out-of-hours services.

Patients or carers contacted were pleased to be give feedback and would be willing to contribute to further reviews or service development.

letter with regular updates about staffing and service issues. These interviews suggested that it would be beneficial (and not too difficult) to involve patients and carers in service design and review, perhaps also in staff training and induction.

Discussion

Conclusions

Anyone working in the NHS is aware of working in a constantly changing environment, but it was helpful to stop and reflect, specifically on the variety and scope of the change experienced by this specific team. Small changes are easily forgotten and this review showed more change than I initially expected. Despite this, it was striking how little the people interviewed noticed; changes that were important to the team seemed to have minimal impact whereas issues that seemed small to healthcare staff loomed large for patients and carers. Preparation for significant changes aimed to minimise the impact on patients, for example, the move from feed being prescribed by the GP to being ordered by the dietitian, which had major implications for the service, went largely unnoticed and generated few of the problems predicted. Changes to feed and equipment in regular use were more significant for patients and carers. Explanation about the reasons for change as well as the practical impact was welcomed by patients and carers, for example, regular reviews of ancillary equipment, such as syringes, to ensure best value.

There was very positive feedback about the service and staff, especially the dietitians. The role of dietetic assistants, who carry out telephone reviews, was less clear to patients and carers, an initial faceto-face visit by the assistant would help start their relationship with people they will support mostly by telephone. Use of new technologies such as Skype, could also be considered with more explanation of the assistant’s role by dietitians during visits. Patients and carers, especially in paediatrics, placed great value on developing a relationship with individual HETF team members, particularly in longterm tube feeding. Some staff changes are unavoidable, while staff rotation and varying caseload can provide better and more flexible support in the longer term. Recognising the importance of relationships with patients and carers helps the team explore ways of minimising the impact of this sort of change, for example, making time for a personal handover to a new dietitian where possible, or producing a news-

Overall, these interviews provided positive feedback for the HETF service and the changes that have been made, with much to learn by making time to listen directly to patients and carers. Not surprisingly, staff perceptions were different to those of patients and carers; issues that loomed large for the team had little impact on service users, partly because we worked to prevent negative impact, but also because their concerns are different.

A patient-centred approach, including listening to patients and carers, as well as explaining and problem solving, is at the heart of HETF support as of so many other areas of dietetics.

Interview Outline • Introduce self and talk a little about the service.

• Ask permission to record the interview and show equipment.

• Introduce the project, explain that there are no right or wrong answers, not checking up on the team, just want to find out about their experience.

• What have they noticed since 2007 (without prompting)?

• Ask about specific changes and how that has affected them.

- No longer need a prescription for feed from the GP. - Dietitian and assistant in contact every three months at least to review feeding.

- Standardising equipment to get best value, e.g. syringes.

- Team based together on one site, more staff.

• Have other service changes affected them positively or negatively, e.g. equipment changes, changes to delivery service, electronic systems?

• Are they aware that they have a named dietitian and regular system of reviews including link with a dietetic assistant?

Bowel cancer diagnosis statistics Recent figures released by the charity Beating Bowel Cancer show that the majority of bowel cancer patients are still diagnosed too late, costing the NHS millions. There is currently a large variation within the NHS across England in terms of early diagnosis of bowel cancer, with the best performing Clinical Commissioning Groups diagnosing 63 percent of patients early, compared with only 30 percent in the worst. The figures show that if every NHS region in England performed as well as the best at diagnosing bowel cancer early (stages 1 and 2), 3,200 lives could be saved and £34 million could be diverted to other bowel cancer services and treatments. www.beatingbowelcancer.org/news/apr2015/lackprogress-diagnosing-bowel-cancer Physical activity statistics The British Heart Foundation’s latest publication Physical Activity Statistics 2015 shows that 44 percent of British adults perform no moderate physical activity. A comparison of 28 countries from the European Union ranks the UK in 16th position based on the frequency of moderate physical activity performed in the last seven days. The Netherlands lead the way in Europe with only 14 percent of adults performing no moderate physical activity, followed by Finland and Denmark (23 percent). The British Heart Foundation expressed their concern that physical inactivity is contributing

Older people and cancer Public Health England and NHS England have updated the publication Older People and Cancer originally published in December 2014. This report summarises what is known about older people and cancer, drawing together information from different sources and studies. This report defines older people as those aged 75 and over and is focused on England; however, other age groups and geographies are presented and compared where it is useful to do so. Each chapter provides high level key messages, followed by a more comprehensive overview of the evidence and statistics. www.ncin.org. uk/publications/ Cancer survival in the UK Public Health England’s National Cancer Intelligence Network has published in conjunction with Cancer Research UK, Major resections by cancer site, in England; 2006 to 2010. Cancer survival in the UK is lower than in many comparable countries. This difference may be caused by a number of factors, including later diagnosis and less access to optimal treatment.

Although surgery can be used in combination with radiotherapy and/ or chemotherapy, experts believe that it is responsible for around half of the cases where cancer is cured, making it the most effective form of treatment.

If you are not going to a sunny beach, or to lush hills this summer (= August), you could go somewhere that offers neither of these attractions (= Manchester), but promises a chance to meet and mingle with progressive dietitians from around the world.

The international conference for dietitians in Manchester in August has the theme: ‘Doing Justice: shaping change through experience, science and imagination’. There will be debates to consider how to promote new understandings for advancing health equity, food justice and nutritional wellbeing using diverse means of knowledge creation.

The themes of the conference involve a critical examination of the dietetic practice that is shaped by familiar norms, but also shaped by less explicit silences.

Critical Dietetics is a fairly new concept, but this event will be the fifth International Conference on this theme. Manchester follows other exciting venues of Chicago, Nova Scotia in Canada and Sydney. The venue will be the Manchester International Conference Centre and full details of the programme and registration are listed on: www.criticaldietetics.org. Star speakers will include Dr Clare Gerada, who was the first female Chair of the Royal College of General Practitioners, with a particular interest in female leadership, and Food Policy expert Dr Geoff Tansey.

The UK host organiser is dietitian Dr Lucy Aphramor, who is one of the founder members of the Critical Dietetics movement. She describes the trigger of her need to re-examine care concepts from thoughts she had during her first dietetics post. “As I sat in clinic in some of the most deprived areas of

NHDmag.com July 2015 - Issue 106

Coventry, using only the knowledge I brought from university, I had a growing sense that I was missing something important that linked people’s lived experience and their health.”

In 2004, Lucy won the Rose Simmonds Special Award, which funded her attendance at the 14th International Congress of Dietetics in Chicago.

This allowed her to develop contacts with many fellow dietitians in the US and Canada, which led to the organisation of a seminar in Canada in 2009 entitled Beyond Nutritionism: Rescuing Dietetics through Critical Dialogue. It was at this event that a declaration was made to launch the concept of Critical Dietetics.

Critical Dietetics is interested in sparking conversations about novel ways of approaching the complex social, political and cultural issues encountered in the broad field of dietetics and nutrition practice, research and education. Some of the multiple perspectives that define the term ‘critical’ may lead to different, perhaps improved ways, to support nutrition aspects of public health, particularly in relation of social and environmental issues.

There is perhaps no full definition of the term Critical Dietetics, but some intentions are captured in the declaration agreed in June 2009. It aspires to capture the relationships between food and health as more than the nutrient contents of foods connecting to

Conference update physiological effects in the body. It is impossible to escape cultural values in discussions of diet and health, but Critical Dietetics attempts to make the assumptions upon which food and health choices are made more visible. Professional strengths come from openness to diversity and debate and themes at the conference will consider many of the social aspects that affect dietetics practice in a scholarly way. It is an opportunity to celebrate what dietitians have achieved and to discuss in what ways the profession could evolve.

Topics and themes to be addressed at the conference in Manchester include the following: • Doing justice to innovation in nutrition and dietetic education, practice, activism, research and practitioner development.

• Student, practitioner and activists’ experiences of speaking and practicing from their own lives and/or disenfranchised positions, or feeling silenced.

• Promoting diverse ways of knowing in dietetics and nutrition, including embodied knowledge.

• What is the role of the medical humanities in nutrition and dietetics?

• Can creativity be taught?

• Arts-based or arts-informed inquiry as a means for challenging knowledge hierarchies and supporting knowledge co-creation.

• Creativity, leadership and equity.

• What conceptual frameworks support a reorientation of health to embrace social justice?

• How can we simultaneously improve nutritional wellbeing and avoid healthism?

And there’s more! Five years ago, the first Dietitian as Artist exhibition was held as part of the Dietitians of Canada Annual Conference in Montreal, and Conference attendees are all invited to take part in the follow-on event Making: An Exhibition of Ourselves.

The Manchester conference is an exciting opportunity for more UK dietitians to discover the vibrant, supportive community of Critical Dietetics. Registration is now open at: www. criticaldietetics.org

A day in the life of a renal dietetics assistant

Charlotte Jennifer-Louise Routen Nutritionist/ Dietetics Assistant, Fresenius

Charlotte is a degree qualified nutritionist with experience working for the NHS and privately both in employed and freelance positions. She enjoys being in the countryside and by the sea, with her family and my dogs. Her favourite place is Cornwall.

Whilst studying for my degree in Nutrition at the University of Nottingham, I worked for NutraTech, a company which creates online diet tools and websites. Once I had graduated in 2010, I set up my own business Route2nutriton and did some work for the NHS and for private companies too. I then went travelling around the world, discovering new cultures and tasting lots of different cuisines.

ments help to determine the patient’s target weight which is important for their comfort and dialysis treatment: if too much water is taken off during HD, the patient’s blood pressure may drop, which often leads to dizziness, cramps and headaches, or if too little is taken off, they can become overloaded which requires further hospital care. The routine measurements also highlight those patients who may require additional support, for example, if they are losing weight readily.

A renal diet can feel very restrictive to patients and can be more difficult to manage if they have other dietary requirements such as coeliac, irritable bowel, diabetes, or if the patient is vegetarian or vegan. It is our job to help make their diets as varied as possible. We often search supermarket websites and visit local stores to find suitable and accessible products for patients. There is a lot of educational material available to the patients as well, such as handouts and diet sheets.

Some of my other jobs include: taking patient’s diet history, chasing patient prescription by ringing their doctors or pharmacy to ensure that they are getting the medication and supplements required, creating new dietetic displays for the patient waiting area, photocopying diet sheets (less

interesting!) and writing up new patient files.

As a renal dietetic assistant there are certain limitations to my job role- I am not permitted to recommend or supply patients with medication such as phosphate binders, renal multivitamins, or nutritional supplements without the permission of a RD. Working within this unit environment, has allowed me to build a strong rapport with patients, which has made me appreciate the importance of good patient-practitioner relationships; we must gain a patient’s trust before they feel comfortable enough to open up and be honest about their eating habits. In turn, this makes our job more effective as it ensures that we get accurate information and can offer tailored advice to help patients achieve nutritional adequacy and optimal health.

I find the renal system really interesting as it is very complex and requires some detective work. It can be hard to get some patients to see the importance of diet as part of their treatment; it requires good communication techniques to encourage adherence.

I thoroughly enjoy my job, there is always something to do or patients to chat to and I can definitely say that it inspired me to continue my studies in dietetics.

The final helping A few weeks ago I read an article in a tabloid newspaper about ‘Britain’s fattest man’. Some days later he also appeared on ‘This Morning’ television.

The article and the programme discussed the ‘takeaway’ lifestyle that this 33-year-old man was living. He was confined to his bed at home and relied on NHS carers. His current calorie intake was estimated to be around 10,000 calories a day. A few days ago I read that he had died. The police said that his death was not being treated as suspicious.

I was going to discuss this in this issue of Helping, but then we were invited for an overnight stay in the Lake District by my Mother-in-law. This obviously took precedence! Whilst there, we visited Allan Bank, a property near Grasmere owned and managed by the National Trust. William Wordsworth lived there for three years and in one of the rooms, Wordsworth’s study, there had been placed an old typewriter with the challenge: ‘What will you write?’

(See pic). Here is my offering, not written, I hasten to add, from the wonderful vista afforded to Wordsworth overlooking the Lake and Rydal Water, but from my dining room table overlooking a glass of wine, much later the following evening.

O mortal man who canst not see A weight you are that should not linger Thus I am glad it is not me Who needs to lift more than a finger And we know what will be will be In life there is no certainty

So you have seen obesity With eyes and mind and heart and soul Your future in your hands to be Your life once fragile, now a whole That looks forever o’er the hills Your golden host of daffodils

But I have seen and tell you so The beauty that you can enjoy Upon this earth so you will know The tasks that must you now employ Lest it be written on your stone Alongside those who are alone

A child you were but are no more Now show your future, let them make A life well lived for three or four Score years and 10 and they will take Your memory on, with thanks to you They’ll live their life, will do, can do.

Stand up and tell me to a man That wandered lonely as a cloud I hear you all say yes he can And gather round, they are so proud That you have conquered mountains high Now see your world, go touch the sky

Recent figures suggest that over 68 million people in the USA are obese. More than the population of the whole of the United Kingdom including Northern Ireland.
