Previous research has shown that the use of melatonin by individuals with irritable bowel syndrome (IBS) has improved symptoms and quality of life (QoL) but did not affect sleep. This research has been shown to have some limitations in that it has been conducted in a small number of individuals and did not use the latest IBS diagnostic criteria. This randomised control trial aimed to determine in 136 individuals with IBS with and without sleep disorders the effects of melatonin on IBS score, gastrointestinal (GI) symptoms, QoL, and sleep. The results showed that compared to placebo, the use of melatonin for 8 weeks resulted in improved IBS score and GI symptoms in individuals with and without sleep disorders. Severity and frequency of abdominal pain, satisfaction with bowel habits, disease impacts on life, and stool consistency were all improved, however frequency of defecations was unaffected. Sleep was improved in those with sleep disorders, but not those without. It was concluded that melatonin can be used to improve IBS and QoL in individuals with or without sleep disorders and may also improve sleep in those with sleep disorders and IBS. This study could be used by healthcare professionals to recommend the use of melatonin to individuals with IBS to improve symptoms and QoL.
Abstract
BACKGROUND Irritable bowel syndrome (IBS) is one of the world's most common gastrointestinal (GI) disorders, and current treatments do not meet patients' demands. This study aimed to investigate melatonin's therapeutic effects on IBS score, GI symptoms, quality of life, and sleep parameters in both groups of IBS patients with and without sleep disorders. METHODS In this randomized double-blinded placebo-controlled trial study, 136 patients with a diagnosis of IBS based on ROME IV criteria were enrolled and then divided into two groups respecting having sleep disorders or not. Patients of each group were randomized in a 1:1 ratio to receive melatonin 6 mg daily (3 mg fasting and 3 mg at bedtime) for 2 months (8 weeks). Blocked randomization was used in this process. All patients were evaluated both at the beginning and the end of the trial regarding IBS score, GI symptoms, quality of life, and sleep parameters through valid questionnaires. RESULTS In both groups of patients with and without sleep disorders, a significant improvement was observed in IBS score and GI symptoms, including the severity and the frequency of abdominal pain, the severity of abdominal bloating, satisfaction with bowel habits, disease's impact on patient's life, and stool consistency; however, there was no significant improvement in the frequency of defecations per week. In patients with sleep disorders, significant improvement in sleep parameters, including subjective sleep quality, sleep latency, sleep duration, sleep efficiency, and daytime dysfunction, was observed, while in patients without sleep disorders, there was no significant improvement in sleep parameters. In addition, quality-of-life improvement was observed in a significant number of melatonin recipients compared to placebo in both groups of patients. CONCLUSION Melatonin can be considered an effective treatment for improving IBS score, GI symptoms, and quality of life in IBS patients with and without sleep disorders. It is also effective to improve sleep parameters in IBS patients with sleep disorders. TRIAL REGISTRATION This study has been registered to the Iranian Registry of Clinical Trials (IRCT) with the approval number IRCT20220104053626N2 on the date of 13/02/2022.

Plain language summary
Digital health interventions (DHIs) have the potential to transform the diagnosis, monitoring, and management of chronic cardiovascular conditions. Many DHIs are widely deployed in health systems across the world, with adoption rapidly increasing in response to the coronavirus disease 2019 pandemic. The aim of this study was to provide an updated synthesis of evidence on the effectiveness of telemedicine in the management of cardiovascular diseases. This study is a systematic review and meta-analysis of seventy-two studies with a total of 127,869 participants, of whom 82,818 (65%) were males and 45051 (35%) were females. Results showed reduced cardiovascular-related mortality and hospitalisation for patients with heart failure who received combined remote telemedicine monitoring and consultation compared with usual care. Authors conclude that the findings of their study suggest a definite role for telemedicine in the management of heart failure, particularly in early treatment optimisation, but the value is less clear for long-term management strategy and other cardiovascular diseases. Thus, future research should focus to address the application of these technologies to unselected populations and longer-term effectiveness.
Abstract
BACKGROUND Telemedicine has been increasingly integrated into chronic disease management through remote patient monitoring and consultation, particularly during the COVID-19 pandemic. We did a systematic review and meta-analysis of studies reporting effectiveness of telemedicine interventions for the management of patients with cardiovascular conditions. METHODS In this systematic review and meta-analysis, we searched PubMed, Scopus, and Cochrane Library from database inception to Jan 18, 2021. We included randomised controlled trials and observational or cohort studies that evaluated the effects of a telemedicine intervention on cardiovascular outcomes for people either at risk (primary prevention) of cardiovascular disease or with established (secondary prevention) cardiovascular disease, and, for the meta-analysis, we included studies that evaluated the effects of a telemedicine intervention on cardiovascular outcomes and risk factors. We excluded studies if there was no clear telemedicine intervention described or if cardiovascular or risk factor outcomes were not clearly reported in relation to the intervention. Two reviewers independently assessed and extracted data from trials and observational and cohort studies using a standardised template. Our primary outcome was cardiovascular-related mortality. We evaluated study quality using Cochrane risk-of-bias and Newcastle-Ottawa scales. The systematic review and the meta-analysis protocol was registered with PROSPERO (CRD42021221010) and the Malaysian National Medical Research Register (NMRR-20-2471-57236). FINDINGS 72 studies, including 127 869 participants, met eligibility criteria, with 34 studies included in meta-analysis (n=13 269 with 6620 [50%] receiving telemedicine). Combined remote monitoring and consultation for patients with heart failure was associated with a reduced risk of cardiovascular-related mortality (risk ratio [RR] 0·83 [95% CI 0·70 to 0·99]; p=0·036) and hospitalisation for a cardiovascular cause (0·71 [0·58 to 0·87]; p=0·0002), mostly in studies with short-term follow-up. There was no effect of telemedicine on all-cause hospitalisation (1·02 [0·94 to 1·10]; p=0·71) or mortality (0·90 [0·77 to 1·06]; p=0·23) in these groups, and no benefits were observed with remote consultation in isolation. Small reductions were observed for systolic blood pressure (mean difference -3·59 [95% CI -5·35 to -1·83] mm Hg; p<0·0001) by remote monitoring and consultation in secondary prevention populations. Small reductions were also observed in body-mass index (mean difference -0·38 [-0·66 to -0·11] kg/m2; p=0·0064) by remote consultation in primary prevention settings. INTERPRETATION Telemedicine including both remote disease monitoring and consultation might reduce short-term cardiovascular-related hospitalisation and mortality risk among patients with heart failure. Future research should evaluate the sustained effects of telemedicine interventions. FUNDING The British Heart Foundation.

Plain language summary
With the continuing spread of COVID-19 and lack of any approved treatments, this paper examines possible strategies for prevention. The data emerging so far highlights that individual health status plays a critical role in determining clinical severity of COVID-19 symptoms ranging from asymptomatic, mild, moderate, to death. Metabolic status, as determined by a patient’s diet, nutrition, age, sex, medical conditions, lifestyle, and environmental factors can therefore be considered preventative strategies to improve the severity of COVID-19 outcomes. Social distancing and personal hygiene are stated as the most effective strategies to prevent or slow spread of the disease. However individual health status, age and the presence of pre-existing comorbidities influences outcomes, as shown by global data highlighting a prevalence in older, males with metabolic conditions; hypertension in 23.7% patients and diabetes in 16.2% of patients. Older males appear more prone to infectious diseases with high pro-inflammatory immune responses and low adaptive immune responses than an older woman. Diet and healthy intestinal and respiratory tract microbiota may also influence immune system competence. Numerous micronutrients are essential for immunocompetence, particularly vitamin A, C, D, E, Bs, iron, selenium, and zinc. A balanced diet, high in colourful fruits and vegetables with a variation of prebiotic fibres, probiotics, and plant polyphenols and phytonutrients, help promote a healthy, diverse microbiota. Oral probiotics may also be beneficial to vulnerable individuals. Vitamin D supplementation is also proving helpful in prevention of acute respiratory tract infections. Other lifestyle factors such as smoking and exposure to environmental toxins should also be considered. Together these preventative measures may reduce personal risk of getting the disease.
Abstract
It is an ugly fact that a significant amount of the world's population will contract SARS-CoV-II infection with the current spreading. While a specific treatment is not yet coming soon, individual risk assessment and management strategies are crucial. The individual preventive and protective measures drive the personal risk of getting the disease. Among the virus-contracted hosts, their different metabolic status, as determined by their diet, nutrition, age, sex, medical conditions, lifestyle, and environmental factors, govern the personal fate toward different clinical severity of COVID-19, from asymptomatic, mild, moderate, to death. The careful individual assessment for the possible dietary, nutritional, medical, lifestyle, and environmental risks, together with the proper relevant risk management strategies, is the sensible way to deal with the pandemic of SARS-CoV-II.

Obesity in children is an increasing problem in Westernised societies; obese children are more at risk of poorer health in the short and long term. The aim of the study was to explore the views of children about the meanings of obesity and body size, shape or weight and their own experience of these issues. This systemic review looked at 28 studies done in UK, conducted after 1997 in children aged 4-11. The review’s findings suggest that for children, the health consequences of obesity seemed to be mostly irrelevant. Impact on their social lives was far more important. Also, despite often having healthy body sizes, children continue to dislike their own bodies. This review highlights the need to consider the social aspect of childhood obesity and that children’s perspectives should be used in the policy making process. The authors conclude that the studies did not fully represent children’s diversity and therefore higher quality research is needed to enable relevant interventions to be put into place.
Abstract
BACKGROUND There are high levels of concern about childhood obesity, with obese children being at higher risk of poorer health both in the short and longer terms. Children's attitudes to, and beliefs about, their bodies have also raised concern. Children themselves have a stake in this debate; their perspectives on this issue can inform the ways in which interventions aim to work.This systematic review of qualitative and quantitative research aimed to explore the views of UK children about the meanings of obesity and body size, shape or weight and their own experiences of these issues. METHODS We conducted sensitive searches of electronic databases and specialist websites, and contacted experts. We included studies published from the start of 1997 which reported the perspectives of UK children aged 4-11 about obesity or body size, shape or weight, and which described key aspects of their methods. Included studies were coded and quality-assessed by two reviewers independently.Findings were synthesised in two analyses: i) an interpretive synthesis of findings from open-ended questions; and ii) an aggregative synthesis of findings from closed questions. We juxtaposed the findings from the two syntheses. The effect of excluding the lowest quality studies was explored. We also consulted young people to explore the credibility of a subset of findings. RESULTS We included 28 studies. Instead of a focus on health, children emphasised the social impact of body size, describing experiences and awareness of abuse and isolation for children with a greater weight. Body size was seen as under the individual's control and children attributed negative characteristics to overweight people. Children actively assessed their own size; many wished their bodies were different and some were anxious about their shape.Reviewers judged that children's engagement and participation in discussion had only rarely been supported in the included studies, and few study findings had depth or breadth. CONCLUSIONS Initiatives need to consider the social aspects of obesity, in particular unhelpful beliefs, attitudes and discriminatory behaviours around body size. Researchers and policy-makers should involve children actively and seek their views on appropriate forms of support around this issue.
