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
Several viruses have been associated with the onset of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), however the data has been controversial. The aim of this observational study of 108 individuals was to assess the presence and type of viruses present in patients with ME/CFS. The results showed that Eppstein-Barr virus (EBV) was more prevalent in individuals with ME/CFS compared to those without. It was concluded that a high rate of EBV was present amongst individuals with ME/CFS and in this subset of individuals EBV may have a role in the development of ME/CFS. This study could be used by healthcare professionals to understand that individuals may be at risk of developing ME/CFS following EBV.
Abstract
Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a disabling multisystem chronic disease. The etiology and pathogenesis of ME/CFS are unknown. Infections of cytomegalovirus (CMV), Epstein-Barr virus (EBV), and human herpesvirus-6 (HHV-6) are suspected as etiological agents for ME/CFS. This study aims to estimate prevalence and type (active/latent) of EBV, CMV, and HHV-6 infections in Bulgarian ME/CFS patients. In the study were included 58 patients with ME/CFS and 50 healthy controls. Virus-specific antibodies were detected by enzyme-linked immunosorbent assay and viral genomic sequences in peripheral blood mononuclear cell (PBMCs) and plasma samples by nested polymerase chain reaction (PCR). We did not observe any significant differences in virus-specific immunoglobulin G and immunoglobulin M positivity rates between patients with ME/CFS and control group. In ME/CFS plasma samples, EBV DNA was found in 24.1%, CMV DNA in 3.4%, and HHV-6 DNA in 1.7% of samples. EBV DNA was detected in 4%, and CMV and HHV-6 DNA were not found in plasma samples of controls. The frequency of viral genome detection in PBMCs of patients and controls was 74% vs 78% for CMV, 81% vs 84% for EBV, and 82.8% vs 82% for HHV-6. The difference in frequency of EBV active infection in ME/CFS and control group was statistically significant (P = .0027). No ME/CFS and control individuals with active CMV and HHV-6 infection were observed. In conclusion, this study using both serological and PCR-based techniques for distinguishing between active and latent infection showed high rate of active EBV infection among patients with ME/CFS indicating that at least in a subset of cases, EBV is important factor for the development of disease.

Plain language summary
A good understanding of the disease course is vital not only for the design of preventative and intervention studies, but also to assess the timing and type of intervention that minimizes disease risk or optimizes prognosis. The aim of this review was to explore the long-term course of Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) and how presentation and pathophysiological abnormalities may vary with time. Literature shows that it is unknown how the initial host response to a stressor or insult compares in individuals who do or do not develop typical symptoms of ME/CFS. However, the return to good health, following exposure to mild or moderate levels of insult, seems to be impeded in ME/CFS when symptoms persist for longer than 3–6 months. Authors sought to provide a simple framework, similar to those of other chronic diseases, in an effort to extend the temporal perception of ME/CFS and better incorporate the less defined pre-illness stages of the disease. In fact, they conclude that by applying this framework to ME/CFS research efforts could better elucidate the pathophysiological mechanisms of the disease and identify potential therapeutic targets at distinct stages.
Abstract
We propose a framework for understanding and interpreting the pathophysiology of Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) that considers wider determinants of health and long-term temporal variation in pathophysiological features and disease phenotype throughout the natural history of the disease. As in other chronic diseases, ME/CFS evolves through different stages, from asymptomatic predisposition, progressing to a prodromal stage, and then to symptomatic disease. Disease incidence depends on genetic makeup and environment factors, the exposure to singular or repeated insults, and the nature of the host response. In people who develop ME/CFS, normal homeostatic processes in response to adverse insults may be replaced by aberrant responses leading to dysfunctional states. Thus, the predominantly neuro-immune manifestations, underlined by a hyper-metabolic state, that characterize early disease, may be followed by various processes leading to multi-systemic abnormalities and related symptoms. This abnormal state and the effects of a range of mediators such as products of oxidative and nitrosamine stress, may lead to progressive cell and metabolic dysfunction culminating in a hypometabolic state with low energy production. These processes do not seem to happen uniformly; although a spiraling of progressive inter-related and self-sustaining abnormalities may ensue, reversion to states of milder abnormalities is possible if the host is able to restate responses to improve homeostatic equilibrium. With time variation in disease presentation, no single ME/CFS case description, set of diagnostic criteria, or molecular feature is currently representative of all patients at different disease stages. While acknowledging its limitations due to the incomplete research evidence, we suggest the proposed framework may support future research design and health care interventions for people with ME/CFS.

Plain language summary
Chronic fatigue syndrome /myalgic encephalomyelitis (CFS/ME) is complex and probably triggered by several interconnected factors and the identification of these is essential to develop better treatments and preventative measures. This systematic scoping review of 1161 studies aimed to discuss potential causal factors of CFS/ME. The results showed that there were several main causal factors that were investigated in the literature and no single factor dominated the research; immunological, psychological/psychosocial/socioeconomic, infectious, and neuroendocrinal/hormonal/metabolic. Studies varied in their design and methods. Interestingly research in this area was at its highest before 1995 and from 2015-2019, studies have markedly decreased. It was concluded that large variations in methods and design of studies of causal factor studies, is problematic. More large, well designed studies are required especially as research has declined recently and considering post covid-19 fatigue. This study could be used by healthcare professionals to understand where there are gaps in the research to design more robust studies in the future.
Abstract
BACKGROUND Chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) is understood as a complex condition, likely triggered and sustained by an interplay of biological, psychological, and social factors. Little oversight exists of the field of causal research. This systematic scoping review explores potential causal factors of CFS/ME as researched by primary studies. METHODS We searched eight databases for primary studies that examined potential causal factors of CFS/ME. Based on title/abstract review, two researchers independently sorted each study's factors into nine main categories and 71 subordinate categories, using a system developed with input given during a 2018 ME conference, specialists and representatives from a ME patient advocacy group, and using BMJ Best Practice's description of CFS/ME etiology. We also extracted data related to study design, size, diagnostic criteria and comparison groups. RESULTS We included 1161 primary studies published between January 1979 and June 2019. Based on title/abstract analysis, no single causal factor dominated in these studies, and studies reported a mean of 2.73 factors. The four most common factors were: immunological (297 studies), psychological (243), infections (198), and neuroendocrinal (198). The most frequent study designs were case-control studies (894 studies) comparing CFS/ME patients with healthy participants. More than half of the studies (that reported study size in the title/abstract) included 100 or fewer participants. CONCLUSION The field of causal hypotheses of CFS/ME is diverse, and we found that the studies examined all the main categories of possible factors that we had defined a priori. Most studies were not designed to adequately explore causality, rather to establish hypotheses. We need larger studies with stronger study designs to gain better knowledge of causal factors of CFS/ME.

Plain language summary
Fibromyalgia syndrome (FMS) is a complex multifaceted condition with chronic widespread pain as the most common symptom. Currently there is no standard diagnostic process nor treatment protocol for individuals diagnosed with FMS as symptoms and co-morbidities vary widely among individuals. Since most dietary advice regarding FMS has been anecdotal, this review evaluates the impact of dietary changes on symptoms related to fibromyalgia and discusses the potential mechanisms by which nutrition could help reduce symptoms. This review included 22 studies that found pain to be significantly improved after the consumption of chlorella green algae, a vegan diet, a low FODMAP diet, coenzyme Q10 and acetyl-L-carnitine. Outcome measures aside from pain were inconclusive. Overall, the authors found insufficient evidence to soundly recommend a specific nutritional intervention for the management of fibromyalgia. They suggest further research is needed that include improved study design, larger sample sizes and measurements of oxidative stress and inflammatory biomarkers.
Abstract
Fibromyalgia syndrome (FMS) is characterised by chronic widespread pain alongside fatigue, poor sleep quality and numerous comorbidities. It is estimated to have a worldwide prevalence of 1.78%, with a predominance in females. Treatment interventions for fibromyalgia have limited success, leading to many patients seeking alternative forms of treatment, including modifications to their diet and lifestyle. The effectiveness of dietary changes in fibromyalgia has not been widely researched or evaluated. This systematic review identified twenty-two studies, including 18 randomised control trials (RCTs) and four cohort studies which were eligible for inclusion. In total these studies investigated 17 different nutritional interventions. Significant improvements in reported pain were observed for those following a vegan diet, as well as with the low fermentable oligo di-mono-saccharides and polyols (FODMAP) diets. Supplementation with Chlorella green algae, coenzyme Q10, acetyl-l-carnitine or a combination of vitamin C and E significantly improved measures of pain. Interpretation of these studies was limited due to the frequent poor quality of the study design, the wide heterogeneity between studies, the small sample size and a high degree of bias. Therefore, there is insufficient evidence to recommend any one particular nutritional intervention for the management of fibromyalgia and further research is needed.

Plain language summary
Seasonal affective disorder (SAD) is a mood disorder characterised by annual depression or bipolar disorder in a seasonal pattern. Recent evidence suggests dietary intervention and nutrition status can affect the symptoms in depressed patients, but none have specifically considered depression among SAD patients. The aim of this review was to assess the associations between diet, eating behaviour and nutrition intervention in SAD patients. Eleven studies were included and found vegetarian diet patterns and alcoholism to be associated with higher SAD prevalence. Additionally, SAD patients tend to consume larger dinners, more snacks, and show more cravings for starch-rich foods. Despite these patterns, dietary supplementation or nutrition intervention did not show benefit for SAD symptoms. Overall, the authors conclude there is a lack of evidence to draw conclusions on dietary pattern and nutritional interventions for preventing and managing SAD. The authors suggest further evidence is needed from larger controlled trials and encourage investigation of the role of the B vitamin group, rather than an isolated B12 supplementation.
Abstract
Background: Seasonal affective disorder (SAD) is a biological and mood disorder with a seasonal pattern. Dietary intervention and nutritional status have been reported to affect SAD severity. The objective of this study was to systematically review the evidence of associations between SAD and diet, eating behavior, and nutrition intervention. Methods: We performed a comprehensive search of MEDLINE, EMBASE, Web of Science, and Google Scholar from inception up to July 1, 2019. Studies that examined diet and eating behaviors in SAD patients and tests of nutrition interventions for SAD were included. Two independent investigators extracted data based on study designs, participants, outcomes, exposures, and association measures. Results: Eleven studies were included: six studies examined distinctive dietary patterns and eating behaviors in SAD patients and five studies explored the efficacy of nutrition interventions for SAD. Vegetarianism and alcoholism were associated with higher SAD prevalence, but normal alcohol intake was not correlated with SAD severity. Compared with non-clinical subjects, SAD patients tended to consume significantly larger dinners and more evening snacks during weekdays and weekends and exhibit a higher frequency of binge eating, external eating, and emotional eating. Additionally, compared to healthy controls, SAD patients presented more cravings for starch-rich food and food with high fiber. However, neither the ingestion of carbohydrate-loaded meals nor Vitamin D/B12 supplementation showed benefit for SAD. Conclusion: Studies suggest that SAD patients may exhibit distinctive diet preferences and eating behaviors, but no current nutrition intervention has demonstrated efficacy for ameliorating SAD symptoms. Further evidence is needed from randomized controlled trials with larger sample sizes and longer durations.

Ageing and the emergence of age-associated illnesses are currently one of the main health challenges in our society. Alzheimer’s disease (AD) is closely associated with ageing and is characterized by progressive memory loss and severe dementia. Currently, there are no therapy options available that halt the progression of the disease. Despite the condition being known for decades, the definitive causes and pathways of the disease and its development are not fully understood. Many drug developments that target some of the known aspects of the disease have failed in the clinical stages, and for nearly 20 years, no new drugs have met FDA approval for the treatment of AD. As increasing evidence suggests diet is an influencing risk factor for AD, the concept of exploring cost-effective, food-derived novel substances with low adverse effects has become more attractive. The first part of this work discusses AD, the prevalence of cognitive decline, limitations of current therapies, the three hallmarks of the disease (autophagy, neuroinflammation, and senescence) and the potential role of food derived substances (nutraceuticals). The second part introduces three nutraceuticals of interest, being epigallocatechin gallate, fisetin, and spermidine. All three compounds have captured scientific interest in regards to aspects of longevity over the recent years. In detail are discussed the current evidence of these compounds concerning autophagy, neuroinflammation, and senescence. This article yields a comprehensive summary of the current evidence from epigallocatechin gallate, fisetin, and spermidine and their potential role in the clinical management of AD.
Abstract
Aging and the emergence of age-associated illnesses are one of the major challenges of our present society. Alzheimer's disease (AD) is closely associated with aging and is defined by increasing memory loss and severe dementia. Currently, there are no therapy options available that halt AD progression. This work investigates three hallmarks of the disease (autophagy, neuroinflammation, and senescence) and systematically analyzes if there is a beneficial effect from three substances derived from food sources, the so called "nutraceuticals" epigallocatechin gallate, fisetin, and spermidine, on these hallmarks. The results imply a positive outlook for the reviewed substances to qualify as a novel treatment option for AD. A combination of nutraceutical substances and other preventive measures could have significant clinical impact in a multi-layered therapy approach to counter AD.

Plain language summary
Iron deficiency is the most common vitamin or mineral deficiency worldwide and is particularly common among pregnant women, infants and young children due to high iron demands during periods of rapid growth. Iron plays an important role in the development of the brain, and animal studies suggest that getting enough iron in pregnancy and early childhood is particularly important. The aims of this systematic review were to (i) investigate the relationship between iron status and brain development and (ii) assess whether this relationship differs according to age or type of development (‘domain’). The researchers looked for studies on iron deficiency or iron supplementation in pregnancy and up to 4 years of age. 26 observational studies and 28 intervention studies were included in the review. There was no clear relationship between iron status and developmental outcomes across any of the ages or domains included. Many of the studies were of low quality and there was a wide variation in study design, along with a lack of research on pregnancy and early infancy. The researchers concluded that evidence for the impact of iron deficiency or iron supplementation on early development is inconsistent. Further high-quality research is needed, particularly within pregnancy and early infancy, which has previously been neglected.
Abstract
One-third of children falter in cognitive development by pre-school age. Iron plays an important role in many neurodevelopmental processes, and animal studies suggest that iron sufficiency in pregnancy and infancy is particularly important for neurodevelopment. However, it is not clear whether iron deficiency directly impacts developmental outcomes, and, if so, whether impact differs by timing of exposure or developmental domain. We searched four databases for studies on iron deficiency or iron supplementation in pregnancy, or at 0-6 months, 6-24 months, or 2-4 years of age. All studies included neurodevelopmental assessments in infants or children up to 4 years old. We then qualitatively synthesized the literature. There was no clear relationship between iron status and developmental outcomes across any of the time windows or domains included. We identified a large quantity of low-quality studies, significant heterogeneity in study design and a lack of research focused on pregnancy and early infancy. In summary, despite good mechanistic evidence for the role of iron in brain development, evidence for the impact of iron deficiency or iron supplementation on early development is inconsistent. Further high-quality research is needed, particularly within pregnancy and early infancy, which has previously been neglected.

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
Besides the high infection and mortality rate, the COVID-19 pandemic also causes considerable psychological stress. Research from previous epidemics and pandemics found that health concerns and anxieties relating to a virus outbreak can have a significant psychological impact and have been linked to behaviours ineffective for disease prevention. Health anxiety exists on a spectrum from absent health awareness to pathological health anxiety or hypochondria. Unhelpful practices, such as excessive online information searching (cyberchondria) or doctor visits can amplify or sustain such anxieties. Furthermore, media consumption during a pandemic has been positively associated with anxiety, and so has been related to dysfunctional emotion regulation (i.e. ruminating, catastrophizing). So far, it was assumed that individuals with pre-existing health anxiety are particularly prone to experience virus anxiety with little numerical evidence to back this up. Hence this study sought to quantify whether during the COVID -19 pandemic, pre-existing health anxiety influenced levels of virus anxiety and whether there was a relationship between cyberchondria and virus anxiety. An online survey was conducted within the German population in March 2020 (N = 1615, female predominant, mean age of = 33.36 years) and data was collected using a series of questionnaires. The outcome was consistent with previous studies showing that about half of the participants reported moderate to severe anxiety associated with COVID-19, women being particularly affected. Predisposition to health anxiety and cyberchondria were consistently positively correlated to virus anxiety. Whereby being well informed and having coping strategies seemed to contribute to reduced levels of virus anxiety. The study may be of interest to those who seek evidence on the association between health anxiety and media consumption in relation to pandemic-associated anxiety.
Abstract
According to cognitive-behavioral models, traits, triggering events, cognitions, and adverse behaviors play a pivotal role in the development and maintenance of health anxiety. During virus outbreaks, anxiety is widespread. However, the role of trait health anxiety, cyberchondria, and coping in the context of virus anxiety during the current COVID-19 pandemic has not yet been studied. An online survey was conducted in the German general population (N = 1615, 79.8 % female, Mage = 33.36 years, SD = 13.18) in mid-March 2020, which included questionnaires on anxiety associated with SARS-CoV-2, trait health anxiety, cyberchondriaPandemic (i.e. excessive online information search), and emotion regulation. The participants reported a significantly increasing virus anxiety in recent months (previous months recorded retrospectively), especially among individuals with heightened trait health anxiety. CyberchondriaPandemic showed positive correlations with current virus anxiety (r = .09-.48), and this relationship was additionally moderated by trait health anxiety. A negative correlation was found between the perception of being informed about the pandemic and the current virus anxiety (r=-.18), with adaptive emotion regulation being a significant moderator for this relationship. The findings suggest that trait health anxiety and cyberchondria serve as risk factors, whereas information about the pandemic and adaptive emotion regulation might represent buffering factors for anxiety during a virus pandemic.
