Plain language summary
Dementia is a chronic condition characterised as a decline in cognitive functioning that leads to dependence in the performance of daily activities, including nutritional sufficiency. As the dis-ease progresses, eating and drinking may become more difficult. The aim of this study was to investigate the effects of oral nutrition supplements (ONS) on nutritional intake and clinical outcomes in older persons with dementia. This study is a systemic review which included ten studies of which 9 where experimental studies (n=6 RCTs; n=3 non RCTs) based on patients with dementia who were undernourished. Results indicate that ONS improved daily intake of energy and protein, compliance was high, and more persons met the recommended nutrition intake. In fact, intervention with ONS improved nutritional status; however, no effects on cognitive or functional outcomes were reported. Authors conclude that there is the need for a more comprehensive intervention plan for people with cognitive impairments that addresses the individual nutritional challenges in order to systematically meet nutritional needs.
Abstract
OBJECTIVE Persons with dementia are at risk of malnutrition, evidenced by low dietary intake, which has consequences for nutritional status, activity of daily living and disease progression. The effects of oral nutrition supplements (ONS) on nutritional intake, nutritional status, and cognitive and physical outcomes in older persons with dementia were evaluated. METHODS PubMed, Medline, Embase, CINAHL and the Cochrane Central Register of Controlled Trials were searched in December 2017, and this was repeated in May 2019. The Preferred Reporting Items for Systematic Reviews and Analysis (PRISMA) checklist was used. Papers were considered if they presented experimental clinical trials using oral nutritional supplements to persons diagnosed with dementia, including Alzheimer's disease and mild cognitive impairment, and conducted in hospitals, nursing homes or homes. RESULTS We included ten articles reporting nine clinical trials. A total of 407 persons with dementia were included, of whom 228 used ONS for 7 to 180 days. Nutritional intake improved by 201 to 600 kcal/day. Energy intake from ordinary foods was not affected, thus ONS improved the persons daily intake of energy and protein. Body weight, muscle mass, and nutritional biomarkers in blood improved in the intervention groups compared with the control groups. No effects on cognition or physical outcomes were observed. CONCLUSION ONS increases the intake of energy and protein and improves nutritional status in persons with dementia; however, RCTs with longer intervention periods are needed to investigate the impact on cognitive and functional outcomes.

Plain language summary
Certain inborn errors of metabolism have been linked to several conditions with intellectual disability (ID). Treating these preventable or treatable forms of ID require the support of experts in nutrition and medicine. However, nutritional measures and diet must be adjusted to the different syndromes and their inherent implications, which requires knowledge of ID in general, and of specific diagnosis groups in particular. In addition, challenging behaviour, lower cognitive functions, and capacity in daily-life activities translate into nutritional problems such as shopping, cooking and eating patterns, including snacking, that require systematic professional support. This study shows that the development of adapted mobile phone programs and apps will be of great value in interventions, educational studies and for persons with ID to help them manage their daily chores and their diet, particularly those with moderate and light ID. Addressing the multifaceted challenges of nutrition and health in persons with ID requires more research and increased priority from funding agencies, along with increased visibility and knowledge of the various forms of ID in general.
Abstract
Intellectual disability (ID) is a condition that affects approximately 1% of the population (Maulik et al, 2011). The numbers may differ across nations, owing to different systems and diagnosis entries or lack of such, but usually range between 0.6 and 3% (Stromme & Valvatne, 1998). Persons with ID are a heterogeneous group with different diagnoses and different levels of intellectual ability. These range from profound (IQ < 20) and serious ID (IQ 20-34) to moderate (IQ 35-49) and light ID (IQ 50-69); this roughly translates into the intellectual capacity of children between 3-12 years of age. More than 75% of persons with ID have the mild form and their intellectual capacity and potential may be underestimated in some cases if IQ is the only diagnostic criteria. However, the range in itself is an important factor to take into account when addressing nutrition and health issues. It is further important to recognize that ID is also a feature of several rare disorders, and many disorders not yet identified, adding to the complexity of this group.

Plain language summary
Undernutrition during childhood may contribute to brain impairments resulting in reduced learning and understanding, which may be irreversible. Foods that are fortified with added vitamins and minerals may help to promote brain regeneration in those who are malnourished. This randomised control trial aimed to assess the effects of a new fortified food on memory and an iron rich component of blood in 1059 children aged 15 months to 7 years. The results showed that memory improved in children under 4 years old, but this was not observed in children over 4 years. Iron rich components of the blood were also increased in children under the age of 4 years but again remained unchanged in those over 4 years old. It was concluded that food fortification was of benefit to memory, brain function and iron rich blood components in children under the age of 4 years old. Although tested in a low-income country, these results may be translatable into middle and affluent countries where children are malnourished due to an unhealthy diet. This study could be used by healthcare professionals to understand the importance of a balanced nutritious diet for a child’s learning and the possibility of recommending fortified foods to children who are malnourished.
Abstract
OBJECTIVE To assess the effects of food supplementation on improving working memory and additional measures including cerebral blood flow in children at risk of undernutrition. DESIGN Randomized controlled trial. SETTING 10 villages in Guinea-Bissau. PARTICIPANTS 1059 children aged 15 months to 7 years; children younger than 4 were the primary population. INTERVENTIONS Supervised isocaloric servings (≈1300 kJ, five mornings each week, 23 weeks) of a new food supplement (NEWSUP, high in plant polyphenols and omega 3 fatty acids, within a wide variety and high fortification of micronutrients, and a high protein content), or a fortified blended food (FBF) used in nutrition programs, or a control meal (traditional rice breakfast). MAIN OUTCOME MEASUREMENTS The primary outcome was working memory, a core executive function predicting long term academic achievement. Additional outcomes were hemoglobin concentration, growth, body composition, and index of cerebral blood flow (CBFi). In addition to an intention-to-treat analysis, a predefined per protocol analysis was conducted in children who consumed at least 75% of the supplement (820/925, 89%). The primary outcome was assessed by a multivariable Poisson model; other outcomes were assessed by multivariable linear mixed models. RESULTS Among children younger than 4, randomization to NEWSUP increased working memory compared with the control meal (rate ratio 1.20, 95% confidence interval 1.02 to 1.41, P=0.03), with a larger effect in the per protocol population (1.25, 1.06 to 1.47, P=0.009). NEWSUP also increased hemoglobin concentration among children with anemia (adjusted mean difference 0.65 g/dL, 95% confidence interval 0.23 to 1.07, P=0.003) compared with the control meal, decreased body mass index z score gain (-0.23, -0.43 to -0.02, P=0.03), and increased lean tissue accretion (2.98 cm2, 0.04 to 5.92, P=0.046) with less fat (-5.82 cm2, -11.28 to -0.36, P=0.04) compared with FBF. Additionally, NEWSUP increased CBFi compared with the control meal and FBF in both age groups combined (1.14 mm2/s×10-8, 0.10 to 2.23, P=0.04 for both comparisons). Among children aged 4 and older, NEWSUP had no significant effect on working memory or anemia, but increased lean tissue compared with FBF (4.31 cm2, 0.34 to 8.28, P=0.03). CONCLUSIONS Childhood undernutrition is associated with long term impairment in cognition. Contrary to current understanding, supplementary feeding for 23 weeks could improve executive function, brain health, and nutritional status in vulnerable young children living in low income countries. Further research is needed to optimize nutritional prescriptions for regenerative improvements in cognitive function, and to test effectiveness in other vulnerable groups.

Plain language summary
All bariatric surgery procedures impact on nutrition to varying degrees and can potentially cause clinically significant deficiencies of micronutrients. The British Obesity and Metabolic Surgery Society (BOMSS) published its first nutritional guidelines in 2014. In fact, the aim of this document is to systematically review the current evidence for preoperative and postoperative biochemical monitoring and micronutrient replacement for adolescents and adults undergoing bariatric surgery, and to update the recommendations for safe practice in the U.K. setting. One hundred and thirty-nine papers were included in the review. Results show that following surgery, the risk of nutritional deficiencies increases because of the impact of bariatric surgery on both oral intake and absorption. Thus, preoperative care should include: - a comprehensive nutritional assessment prior to bariatric surgery, - a clinically investigative and corrective approach of nutritional deficiencies before surgery, - preparatory support and education by a dietitian, and - guidance on following a low calorie/low carbohydrate diet. Whereas, postoperative care should include access to lifelong monitoring following bariatric surgery to ensure that nutritional requirements are met, and risks of developing post-bariatric surgery related nutritional deficiencies are reduced. Authors conclude that these guidelines have the potential to improve clinical practice and safety for people undergoing bariatric surgery and should be considered for adoption by healthcare organizations.
Abstract
Bariatric surgery is recognized as the most clinically and cost-effective treatment for people with severe and complex obesity. Many people presenting for surgery have pre-existing low vitamin and mineral concentrations. The incidence of these may increase after bariatric surgery as all procedures potentially cause clinically significant micronutrient deficiencies. Therefore, preparation for surgery and long-term nutritional monitoring and follow-up are essential components of bariatric surgical care. These guidelines update the 2014 British Obesity and Metabolic Surgery Society nutritional guidelines. Since the 2014 guidelines, the working group has been expanded to include healthcare professionals working in specialist and non-specialist care as well as patient representatives. In addition, in these updated guidelines, the current evidence has been systematically reviewed for adults and adolescents undergoing the following procedures: adjustable gastric band, sleeve gastrectomy, Roux-en-Y gastric bypass and biliopancreatic diversion/duodenal switch. Using methods based on Scottish Intercollegiate Guidelines Network methodology, the levels of evidence and recommendations have been graded. These guidelines are comprehensive, encompassing preoperative and postoperative biochemical monitoring, vitamin and mineral supplementation and correction of nutrition deficiencies before, and following bariatric surgery, and make recommendations for safe clinical practice in the U.K. setting.

Selecting foods for a day is easily influenced by the social environment and eating together or alone plays a big role in that decision. The study aims to evaluate the association between diet quality of the modern Korean adult population based on the eating behaviour and the socioeconomic factors that influence their diet quality. The study is a cross-sectional study which included 3365 men and 5258 women aged between 19 and 64 years. The study included demographic, socioeconomics, and health behaviour factors as covariates. Results indicate that diet quality is influence by eating behaviour. Authors observed that when Korean adults ate without a companion, their diet quality was significantly lower than those who consistently ate with others. Furthermore, from the higher education to lower education level, the diet quality declined when they eat alone. Authors conclude that many Korean adults are experiencing low diet quality when they eat alone. The study provides evidence to promote interventions to improve diet quality among the public.
Abstract
BACKGROUND To discover the association between eating alone and diet quality among Korean adults who eat alone measured by the mean adequacy ratio (MAR), METHODS The cross-sectional study in diet quality which was measured by nutrient intakes, indicated as MAR and nutrient adequacy ratio (NAR) with the Korean National Health and Nutrition Examination Survey (KNHANES) VI 2013-2015 data. Study population was 8523 Korean adults. Multiple linear regression was performed to identify the association between eating behaviour and MAR and further study analysed how socioeconomic factors influence the diet quality of those who eat alone. RESULTS We found that the diet quality of people who eat alone was lower than that of people who eat together in both male (β: - 0.110, p = 0.002) and female participants (β: - 0.069, p = 0.005). Among who eats alone, the socioeconomic factors that negatively influenced MAR with the living arrangement, education level, income levels, and various occupation classifications. CONCLUSIONS People who eat alone have nutrition intake below the recommended amount. This could lead to serious health problems not only to those who are socially disadvantaged but also those who are in a higher social stratum. Policy-makers should develop strategies to enhance diet quality to prevent potential risk factors.
