Coeliac disease (CD) is an autoimmune disorder triggered by the ingestion of gluten in genetically susceptible individuals. A wide range of extraintestinal manifestations has been attributed to CD, changing the classic perception of a disease limited to the intestine, to a multisystem disorder. The aim of this study was to analyse the published neuropathology of confirmed cases of gluten-related neurological dysfunction to aid our understanding of the pathogenesis. CD can therefore manifest with dental problems, consequences of malabsorption, skin and neurological disorders. This study is a systematic review of thirty-two neurological disorder focused studies. Results show that: - the neuropathological findings in gluten-related neurological disorders are widespread and not limited to the cerebellum. - the pathology is immune mediated and not related to vitamin or trace elements deficiencies. - the pathophysiology of neurological damage in the context of gluten sensitivity has an immune mediated basis. - more gluten-related neurological disorders affected men (57%), which was even higher in the ataxia group (76%). - transglutaminase 6 antibodies might be helpful in the diagnostic workup of gluten-related neurological disorders. Authors conclude that the current evidence is suggestive of both humoral and cell-mediated immunological responses. Further research is required to investigate the underlying neuropathological mechanism by characterisation of the inflammatory cell infiltrate and identification of target epitopes.
Abstract
Gluten-related neurological disorders (GRND) represent a spectrum of neurological manifestations that are triggered by gluten. In coeliac disease, a T-cell mediated enteropathy is triggered by gluten in genetically predisposed individuals. The underlying pathological mechanism of the neurological dysfunction is not yet clear. The aim of this review is to collate existing neuropathological findings in GRND as a means of aiding the understanding of the pathophysiology. A systematic search of the Pubmed Database yielded 188 articles, of which 32 were included, containing 98 eligible cases with a description of pathological findings in GRND. In gluten ataxia, loss of Purkinje cells, atrophy, gliosis and astrocytosis were apparent, as well as diffuse lymphocytic infiltration and perivascular cuffing with lymphocytes. In patients with large-fiber neuropathy, nerve biopsies revealed axonopathy, loss of myelinated fibers and focal and perivascular infiltration by inflammatory cells. Inflammatory infiltrate was also observed in muscle in myopathy and in cerebrum of patients with encephalopathy and patients with epilepsy. Such changes were not seen in skin biopsies from patients with small fiber neuropathies. The findings from this systematic review suggest an immune mediated pathogenesis for GRND. Future research should focus on the characterization of the inflammatory cell infiltrates and identifying target epitopes.

Plain language summary
Type 2 Diabetes is considered a lifelong condition, but calorie restriction or weight loss can lead to complete remission. Patients newly diagnosed with Type 2 Diabetic may benefit from behavioural change over the long run. When Type 2 Diabetes is diagnosed early in the disease trajectory, it may increase the patient's motivation and make them more receptive to weight-loss interventions. This prospective cohort study included 865 newly diagnosed Type 2 diabetic patients from the ADDICTION Cambridge Trial, a pragmatic, parallel-group cluster randomised controlled trial. The study assessed the relationship between behaviour change and weight loss and the prospect of type 2 diabetes remission in the first year, following four years and after five years without intense dietary or lifestyle intervention in patients. 30% of the patients achieved diabetes remission at 5-year follow-up, with a significant likelihood of remission among those who achieved ≥ 10% weight loss in the first year of diagnosis. A self-reported change in intake of alcohol units was found to be the only consistent association between behaviour change and remission in this study. The role of behaviour change in the remission of diabetes requires further robust research. This study will help healthcare professionals understand the association between weight loss and remission in diabetic patients.
Abstract
AIM: To quantify the association between behaviour change and weight loss after diagnosis of Type 2 diabetes, and the likelihood of remission of diabetes at 5-year follow-up. METHOD We conducted a prospective cohort study in 867 people with newly diagnosed diabetes aged 40-69 years from the ADDITION-Cambridge trial. Participants were identified via stepwise screening between 2002 and 2006, and underwent assessment of weight change, physical activity (EPAQ2 questionnaire), diet (plasma vitamin C and self-report), and alcohol consumption (self-report) at baseline and 1 year after diagnosis. Remission was examined at 5 years after diabetes diagnosis via HbA1c level. We constructed log binomial regression models to quantify the association between change in behaviour and weight over both the first year after diagnosis and the subsequent 1-5 years, as well as remission at 5-year follow-up. RESULTS Diabetes remission was achieved in 257 participants (30%) at 5-year follow-up. Compared with people who maintained the same weight, those who achieved ≥ 10% weight loss in the first year after diagnosis had a significantly higher likelihood of remission [risk ratio 1.77 (95% CI 1.32 to 2.38; p<0.01)]. In the subsequent 1-5 years, achieving ≥10% weight loss was also associated with remission [risk ratio 2.43 (95% CI 1.78 to 3.31); p<0.01]. CONCLUSION In a population-based sample of adults with screen-detected Type 2 diabetes, weight loss of ≥10% early in the disease trajectory was associated with a doubling of the likelihood of remission at 5 years. This was achieved without intensive lifestyle interventions or extreme calorie restrictions. Greater attention should be paid to enabling people to achieve weight loss following diagnosis of Type 2 diabetes.

Plain language summary
Covid-19 may cause brain dysfunction evidenced by symptoms individuals experience once they have contracted the disease. Loss of smell, taste and confusion have all been reported by patients and a number of severe cases have reported incidences of stroke. These are all of concern, as Covid-19 can severely affect the elderly who ordinarily are the most likely to suffer from brain disorders. This small review paper of 27 studies stated that there are four possible ways in which Covid-19 may affect the brain, which put Covid-19 sufferers at an increased risk of long-term brain disorders. This was supported by findings, which showed one third of Covid-19 patients leave hospital with evidence of brain dysfunction. Inflammation was heavily reviewed by the authors as a possible causal factor. It was concluded that patients who survive Covid-19 infection are at an increased risk for developing brain disorders such as Alzheimer's disease, however it was acknowledged that further studies are required. Clinicians could use this study to understand the possible need for both short-term and long-term monitoring of brain function in individuals who have survived Covid-19, especially if they are elderly.
Abstract
Increasing evidence suggests that infection with Sars-CoV-2 causes neurological deficits in a substantial proportion of affected patients. While these symptoms arise acutely during the course of infection, less is known about the possible long-term consequences for the brain. Severely affected COVID-19 cases experience high levels of proinflammatory cytokines and acute respiratory dysfunction and often require assisted ventilation. All these factors have been suggested to cause cognitive decline. Pathogenetically, this may result from direct negative effects of the immune reaction, acceleration or aggravation of pre-existing cognitive deficits, or de novo induction of a neurodegenerative disease. This article summarizes the current understanding of neurological symptoms of COVID-19 and hypothesizes that affected patients may be at higher risk of developing cognitive decline after overcoming the primary COVID-19 infection. A structured prospective evaluation should analyze the likelihood, time course, and severity of cognitive impairment following the COVID-19 pandemic.

Plain language summary
Current quarantine measures aim to reduce transmission of Covid-19 to prevent deaths and ensure healthcare systems do not become overwhelmed. However the long term effects of quarantine can have negative consequences on an individual’s health. Stress, increased heart related diseases and affected mental health have all been implicated as outcomes of extended quarantine. This review paper aimed to assess the impact of quarantine on lifestyle factors such as nutrition, physical activity and the role of technology in a Covid-19 adapting world. The paper outlines that quarantine may increase chronic stress, which activates certain nervous and hormonal systems, resulting in adverse affects on the heart. However physical data on this in relation to quarantine is lacking. Quarantine can also lead to changes in lifestyle habits, such as an increased intake of sugar-rich food, alcohol and a decrease in physical activity, which may be maintained after quarantine has lifted in response to economic crisis. Stress related eating, the availability of fresh foods and restricted shop opening hours were implicated as reasons why many people switch to unhealthy eating habits. Prevention of Covid-19 through the use of vitamin D was discussed, due to its ability to protect against infection and inflammation, especially in those who are deficient. Preventative measures to quarantine related stress and reducing the risk of heart related diseases were also highlighted through staying physically active and healthy eating strategies. The paper concluded that after the Covid-19 pandemic it is likely that there will be an increase in heart related diseases. Clinicians could use this paper to encourage healthy eating and exercise in patients who have heart related diseases or to decrease the risk of heart related diseases in patients who are suffering from stress as a direct result of quarantine.
Abstract
AIMS: CoV-19/SARS-CoV-2 is a highly pathogenic virus that is causing a global pandemic with a high number of deaths and infected people. To contain the diffusion of infection, several governments have enforced restrictions on outdoor activities or even collective quarantine on the population. The present commentary briefly analyzes the effects of quarantine on lifestyle, including nutrition and physical activity and the impact of new technologies in dealing with this situation. DATA SYNTHESIS Quarantine is associated with stress and depression leading to unhealthy diet and reduced physical activity. A diet poor in fruit and vegetables is frequent during isolation, with a consequent low intake of antioxidants and vitamins. However, vitamins have recently been identified as a principal weapon in the fight against the Cov-19 virus. Some reports suggest that Vitamin D could exert a protective effect on such infection. During quarantine, strategies to further increase home-based physical activity and to encourage adherence to a healthy diet should be implemented. The WHO has just released guidance for people in self-quarantine, those without any symptoms or diagnosis of acute respiratory illness, which provides practical advice on how to stay active and reduce sedentary behavior while at home. CONCLUSION Quarantine carries some long-term effects on cardiovascular disease, mainly related to unhealthy lifestyle and anxiety. Following quarantine, a global action supporting healthy diet and physical activity is mandatory to encourage people to return to a good lifestyle routine.

Plain language summary
Research suggests that weight stigma is increasing and is associated with multiple negative health and psychological outcomes. Public health messaging presently emphasises weight gain as lack of personal control of diet and exercise, which contributes to the stigma and ignores the myriad of uncontrollable factors that also contribute to weight gain. One component of weight gain is food addiction, in which food is shown to be as rewarding to the brain as other addictive substances. It is currently unclear whether an explanation of the food addiction model (FAM) will affect weight stigma, and there is a need to understand the factors that contribute and reinforce weight stigmatisation. The aim of this study is to assess whether providing a FAM explanation for weight gain would impact expressions of weight stigma. Two experiments were done in which college students were randomly allocated to read a simulated article that focused on either food addiction or diet and exercise as contributing factors to obesity. The participants then completed a survey assessing their perception of obesity. This study found the FAM explanation resulted in a significantly lower weight stigma. Based on these results, the authors suggest current public health messaging that attributes obesity to lack of personal control needs to be changed as it exacerbates weight stigma.
Abstract
There is increasing scientific and public support for the notion that some foods may be addictive, and that poor weight control and obesity may, for some people, stem from having a food addiction. However, it remains unclear how a food addiction model (FAM) explanation for obesity and weight control will affect weight stigma. In two experiments (N = 530 and N = 690), we tested the effect of a food addiction explanation for obesity and weight control on weight stigma. In Experiment 1, participants who received a FAM explanation for weight control and obesity reported lower weight stigma scores (e.g., less dislike of 'fat people', and lower personal willpower blame) than those receiving an explanation emphasizing diet and exercise (F(4,525) = 7.675, p = 0.006; and F(4,525) = 5.393, p = 0.021, respectively). In Experiment 2, there was a significant group difference for the dislike of 'fat people' stigma measure (F(5,684) = 5.157, p = 0.006), but not for personal willpower weight stigma (F(5,684) = 0.217, p = 0.81). Participants receiving the diet and exercise explanation had greater dislike of 'fat people' than those in the FAM explanation and control group (p values < 0.05), with no difference between the FAM and control groups (p >0.05). The FAM explanation for weight control and obesity did not increase weight stigma and resulted in lower stigma than the diet and exercise explanation that attributes obesity to personal control. The results highlight the importance of health messaging about the causes of obesity and the need for communications that do not exacerbate weight stigma.

Plain language summary
Polycystic Ovary Syndrome (PCOS) is a common endocrine disorder affecting women in their reproductive years. The condition is often associated with higher rates of depression and anxiety, particularly with a Body Mass Index (BMI) of >30. As weight-loss has shown to improve a host of symptoms experienced in PCOS, the authors sought to investigate whether weight-loss would also lead to a reduction in depressive symptoms. This secondary analysis of a longitudinal, randomised trial of 155 women, compared a combined lifestyle intervention of diet advice, eating behaviour, exercise and standardised Cognitive Behaviour Therapy (CBT) to standard advice for weight reduction. Over a 12-months the chosen lifestyle interventions demonstrated a sustained improvement in self-assessed depression scores, though independent of weight-loss. However, weight-loss itself was closely linked with improved body image and self-esteem. Additional monitoring of hormones (androgens, insulin, cortisol) and calculations for insulin sensitivity (HOMA-IR ) did not show any direct link with depressive scores. This study affirms the benefit of integrative lifestyle approaches on emotional well-being in women with PCOS. Practitioners might find it of interest that improvements in emotional well-being can occur independent of weight loss in individuals experiencing depressive symptoms with PCOS.
Abstract
Many women with Polycystic Ovary Syndrome (PCOS) report high depression rates. The relationship between PCOS and these high depression rates is unclear. Two-component lifestyle interventions have revealed short-term effects on depression scores in this group of women. In general, 3-component interventions including diet, exercise, and cognitive behavioral therapy (CBT) are more effective in the long-term to improve emotional well-being. This has not yet been studied in women with PCOS. This study examined the effect of 20 CBT lifestyle (LS) sessions combined with a healthy diet and physical therapy with or without 9 months additional feedback through Short Message Service (SMS) via mobile phone, compared to care as usual (CAU, involving advice to lose weight). In this secondary analysis, 155 women with PCOS and a BMI above 25 kg/m2 were eligible. Depression scores decreased significantly in the LS programme compared to CAU (P = 0.045). In both the LS programme without SMS (P = 0.036) and the LS programme with SMS (P = 0.011) depression scores decreased while no change was observed in CAU (P = 0.875). Self-esteem scores improved significantly in the LS programme compared to CAU (P = 0.027). No differences in body image scores were observed in LS participants compared to CAU (P = 0.087), although body image improved significantly in both the LS without SMS (P = 0.001) and with SMS (P = 0.008) study arms. We found no significant mediating role by androgens in the relationship between LS participants and emotional well-being. Only weight-loss mediated the relationship between LS and self-esteem. To conclude, a three-component lifestyle intervention programme with or without additional SMS resulted in significant improvements in depression and self-esteem compared to CAU, in women with PCOS, obesity, and a wish to achieve a pregnancy. Testosterone, androstenedione, DHEA, insulin, HOMA-IR, and cortisol did not mediate this effect. Weight loss mediated the effects on self-esteem but not on depression and body-image. This suggests that lifestyle treatment independent of weight loss can reduce depression and body-image, but both lifestyle treatment and weight loss can improve self-esteem. Thus, a three-component lifestyle intervention based on CBT could prove successful in improving mood in women with PCOS who are overweight or obese and attempting to become pregnant.

Plain language summary
Being overweight or obese is extremely harmful and can affect both physical and psychological health, increasing the risk of chronic non-communicable diseases. The aim of this study was to evaluate the impact of a comprehensive family-individual-school-based intervention approach involving obesity-related health education, diet control, and physical exercise on the quality of life (QoL) of Chinese children and adolescents. This study is a cluster-based randomized controlled trial involving 4 schools. The schools were randomly separated into 2 groups: an intervention group that received comprehensive obesity-related interventions and a control group that received no specific interventions. The most robust finding of this study was improved psychological QoL in the intervention group. However, social and pubertal dimensions as well as overall QoL were also all significantly improved following the implementation of the family-individual-school-based intervention strategy. The intervention effect was more substantial in boys than in girls. Authors conclude that family-individual-school-based interventions incorporating obesity-related health education, physical exercise, and diet control can improve psychological and pubertal well-being, as well as overall QoL in children, particularly among boys.
Abstract
BACKGROUND AND PURPOSE Obesity has become a serious public health problem and family- and school-based interventions including physical exercise and diet control have been widely applied to attempt to combat this issue. The purpose of our study was to verify the effectiveness of an obesity-related comprehensive intervention model aimed at improving quality of life (QoL) among adolescents. METHODS A cluster randomized controlled trial (RCT) was conducted involving 948 subjects who were divided into an intervention group (n = 518) and a control group (n = 430). The intervention group received 1 year of obesity-related health education, physical exercise, and diet control. Their baseline body mass index (BMI) was calculated, and their QoL and basic information were assessed both before and after the intervention period using a self-designed Adolescent Quality of Life Scale and a basic information questionnaire. RESULTS After the intervention, significant differences in the psychological, social, and pubertal dimensions, and in total QoL (P < 0.05) were observed in the intervention group relative to the control group. Improved psychological QoL in the intervention group was our most robust study finding, with increases in psychological (B = 1.883, SE = 0.646, P = 0.004), pubertal (B = 0.853, SE = 0.296, P = 0.004) and total (B = 3.024, SE = 1.214, P = 0.013) QoL all being higher in this group. This intervention effect was found to be more substantial in boys than in girls. CONCLUSIONS Family-individual-school-based interventions combining obesity-related health education, physical exercise, and diet control can improve psychological, pubertal, and total QoL in children, with these effects being most pronounced in boys.

Plain language summary
Exercise is a long-standing remedy for nearly all of obesity’s comorbidities and often recommended as an economical and health-promoting option for weight loss and weight loss maintenance. The aim of this study was to investigate the effect of exercise on food reinforcement (reward-driven feeding), and to examine whether changes in body composition would be correlated with changes in food reinforcement. This study is randomized controlled trial with a total of 52 participants aged 18 to 40 years. Participants were randomly assigned to one of the three groups (six exercise sessions per week, two sessions per week, and sedentary control). Results indicate that there is great variability in individuals’ change in food reinforcement after a 12-week aerobic exercise intervention. Furthermore, those who did increase their food reinforcement were also those who lost the greatest amount of fat-free mass post-intervention. Authors conclude that preventing the loss of fat-free mass may be a valuable piece to a weight loss programme (with resistance training or dietary protein intake as adjunct therapy).
Abstract
BACKGROUND Obesity remains a primary threat to the health of most Americans, with over 66% considered overweight or obese with a body mass index (BMI) of 25 kg/m2 or greater. A common treatment option many believe to be effective, and therefore turn to, is exercise. However, the amount of weight loss from exercise training is often disappointingly less than expected with greater amounts of exercise not always promoting greater weight loss. Increases in energy intake have been prescribed as the primary reason for this lack of weight loss success with exercise. Research has mostly focused on alterations in hormonal mediators of appetite (e.g.: ghrelin, peptide YY, GLP-1, pancreatic polypeptide, and leptin) that may increase hunger and/or reduce satiety to promote greater energy intake with exercise training. A less understood mechanism that may be working to increase energy intake with exercise is reward-driven feeding, a strong predictor of energy intake and weight status but rarely analyzed in the context of exercise. DESIGN Sedentary men and women (BMI: 25-35 kg/m2, N = 52) were randomized into parallel aerobic exercise training groups partaking in either two or six exercise sessions/week, or sedentary control for 12 weeks. METHODS The reinforcing value of food was measured by an operant responding progressive ratio schedule task (the behavioral choice task) to determine how much work participants were willing to perform for access to a healthy food option relative to a less healthy food option before and after the exercise intervention. Body composition and resting energy expenditure were assessed via DXA and indirect calorimetry, respectively, at baseline and post testing. RESULTS Changes in fat-free mass predicted the change in total amount of operant responding for food (healthy and unhealthy). There were no correlations between changes in the reinforcing value of one type of food (healthy vs unhealthy) to changes in body composition. CONCLUSION In support of previous work, reductions in fat-free mass resulting from an aerobic exercise intervention aimed at weight loss plays an important role in energy balance regulation by increasing operant responding for food.

Weight gain is a well-known consequence of smoking cessation. The aim of this study was to compare standard stop smoking behavioural support with an intervention that, in addition to providing standard stop smoking support, included personalised weight management support, provided by Slimming World. This study is a parallel group, individually randomised controlled trial. Participants were randomised (1:1) to usual care or Slimming World with usual care. Stop smoking advisors were unaware of the randomisation sequence. Results showed that referral to the Slimming World programme plus usual stop smoking support achieved significantly less weight gain than usual stop smoking support alone. Furthermore, percentage quit was no worse in the treatment than the control group. Authors conclude that referral to a behavioural weight loss programme may be a pragmatic option within stop smoking clinics.
Abstract
INTRODUCTION Most people who stop smoking gain weight. Dietary modification may seem an obvious solution, but food restriction may increase cigarette craving and smoking relapse. TRIAL DESIGN An unblinded parallel randomised controlled trial. METHODS Participants were adult smokers with a body mass index greater or equal to 23 kg/m2. Setting was National Health Service commissioned Stop Smoking Services, interventions were referral to a commercial weight management programme, plus stop smoking support (treatment group), compared with stop smoking support alone (control group). Objective was to compare weight change between interventions in smoking abstainers and not abstinent rates in all. Primary outcome was change in weight (kg) at 12 weeks. Randomisation sequence was computer generated and concealed until allocation. RESULTS Seventy-six participants were recruited, 37 were randomised to the treatment group and 39 to the control group. Change in weight was analysed in long-term abstainers (13 treatment, 14 control) only because the aim was to prevent weight gain associated with smoking cessation. Abstinence was analysed on an intention-to-treat basis (37 treatment, 39 control). At 12 weeks weight gain was less in the treatment than the control group with an adjusted mean difference of -2.3 kg 95% CI (-4.4 to -0.1). Craving scores were lower (Mood and Physical Symptoms Scale craving domain -1.6 (-2.7 to -0.5)) and quit rates were higher in the treatment than the control group (32% vs 21%), although the trial was not powered to superiority in cravings and quit rates. No adverse events or side effects were reported. CONCLUSION In people who are obese and want to quit smoking, these data provide modest encouragement that providing weight management at the time of quitting may be helpful. Those who are not obese, but who are informed about potential weight gain during their quit attempt, were uninterested in a weight management programme. TRIAL REGISTRATION NUMBER ISRCTN65705512.

Plain language summary
Bariatric surgery is currently the most effective method of weight loss for individuals with obesity. However sustained weight loss after surgery can be hindered by unhealthy behaviours that have sustained since before the procedure. Motivational, educational, diet and exercise programmes have been shown to help sustain weight loss following surgery. This non-randomised control trial over 12 months, aimed to assess the effects of a motivational, educational diet and exercise programme on fitness and quality of life in 82 individuals following bariatric surgery. The results showed that a diet and exercise programme improved quality of life and fitness. There was an increased daily intake of fruits and vegetables, eating behaviours were improved and there was a greater weight loss in those following the programme. It was concluded that the diet and exercise programme was responsible for behavioural changes that ensured better quality of life and sustained weight loss following surgery. Health care professionals could use this study to understand the need to recommend motivational and educationally based diet and exercise programme to patients following bariatric surgery.
Abstract
INTRODUCTION Unhealthy lifestyles may hinder bariatric surgery outcomes. This non-randomized controlled study aimed to evaluate the effects of an integrated post-operative exercise-based educational and motivational program in improving behaviors, quality of life, anthropometric features, cardiorespiratory and physical fitness in bariatric patients respect to the only surgical intervention. METHODS A group of adult sedentary bariatric patients chose to attend a 12-month exercise program integrated with diet education and motivational support, or to receive usual care. Dietary habits, binge eating disorder, physical activity, obesity-related quality of life, Body Mass Index, waist and hip circumference, VO2max, strength and flexibility were assessed at the start and at the end of the study in both groups. RESULTS On a total of 82 patients enrolled, follow-up measures were obtained from 28 (85.7% females, mean age 38.2±8.7) and 42 (71.4% females, mean age 40.2±9.5) patients included in the intervention and control group, respectively. All the behavioral and physical outcomes improved significantly in the participants to the intervention, while the control group showed lesser changes, especially regarding quality of life and physical fitness. CONCLUSIONS Notwithstanding the self-selection, these results suggest that a timely postoperative behavioral multidisciplinary program for bariatric patients may be effective in establishing healthy behaviors which can lead to better surgery outcomes.
