Plain language summary
Children exposed to early life stress (ELS) show alterations in brain development and are at increased risk of developing mental illness. This study aims to clarify whether ELS influences the gut microbiome and whether this can be a predictor for the development of mental disorders. 13 articles were included in this systemic review. 4 looked at pre-natal stress and 9 at post-natal stress. Prenatal stress (via maternal stress) may be associated with an increase in Proteobacteria phylum and with a lower abundance of Bifidobacterium and lactic acid bacteria. In the postnatal group, greater microbiome diversity was related to lower depression and anxiety. In boys scores for adaptive skills were higher in those with good levels of Bifidobacterium. A positive association was found between EA (early adversity) experiences and gastrointestinal symptoms and anxiety. This review demonstrates links between ELS and gut microbiome changes. Further research will be necessary to draw more robust conclusions.

Summary Review:
Introduction
A systematic review was conducted to consolidate clinical evidence examining the impact of early life stress (ELS) on the human intestinal microbiome.
Method
Thirteen observational studies were included in the review, sourced from Pubmed, Scopus, Web of Science, and EMBASE. Methodological quality was assessed using the Newcastle-Ottawa Assessment Scale (NOS), with most studies scoring seven or eight out of nine stars.
Study designs varied, including prospective prenatal studies, postnatal longitudinal studies, case-control studies, and cross-sectional studies. Four prenatal studies were prospective in design. The other nine postnatal studies included one longitudinal study, five case-control studies, and three cross-sectional studies. All 13 studies were published between 2015 and 2022. Because study designs and outcome assessments varied, the results were presented in a narrative form. Data was extracted by 2 independent authors.
Results
The primary findings from the review were as follows:
- Four longitudinal stress studies indicated that pregnant mothers experiencing psychological stress, increased cortisol levels, HIV, and lack of social support exhibited a lower abundance of beneficial Bifidobacterium and an increased abundance of Enterobacter genus.
- One postnatal stress longitudinal study (n=260) demonstrated lower depression and anxiety and improved internalising behaviour in patients with high microbiome diversity.
- . One postnatal stress case-control study (n=344) showed changes in the microbiome and an abundance of several bacterial taxa in stressed groups, including genera Prevotella, Bacteroides (Bacteroidetes), Coprococcus, Streptococcus, and Escherichia.
- One cross-sectional study of 128 adults without psychiatric conditions revealed that higher stress correlated with increased levels of Bacteroides, Parabacteroides, Rhodococcus, Methanobrevibacter, and Roseburia at the genus level, as well as lower Phascolarcto bacterium and Firmicutes at the phylum level.
- One large prospective study (n=446) found infants exposed to higher cumulative stress exhibited an increased relative abundance of Proteobacteria groups and lower Bifidobacterium.
Conclusion:
Due to the inconsistency of study designs and their results this review failed to find consensus microbiome signatures associated with pre- or postnatal stress, or both.
Clinical practice applications:
- Early life stress, and alterations in the gut microbiome, have been linked to mental health conditions
- Maternal prenatal stress may be linked to emotional, behavioural, and cognitive outcomes in infants.
Considerations for future research:
- Future research should standardise questionnaires, to ensure consistency and comparability across studies
- Additionally, future studies should consider using standard procedures and specific species and strain resolution shotgun metagenomics sequencing
- Consideration should be given to the influence of environmental variables (diet, physical activity, etc.) and sex in gut microbiome analysis.
Abstract
Exposure to early life stress (ELS), prenatal or postnatal during childhood and adolescence, can significantly impact mental and physical health. The role of the intestinal microbiome in human health, and particularly mental health, is becoming increasingly evident. This systematic review aims to summarize the clinical data evaluating the effect of ELS on the human intestinal microbiome. The systematic review (CRD42022351092) was performed following PRISMA guidelines, with ELS considered as exposure to psychological stressors prenatally and during early life (childhood and adolescence). Thirteen articles met all inclusion criteria, and all studies reviewed found a link between ELS and the gut microbiome in both prenatal and postnatal periods. However, we failed to find consensus microbiome signatures associated with pre- or postnatal stress, or both. The inconsistency of results is likely attributed to various factors such as different experimental designs, ages examined, questionnaires, timing of sample collection and analysis methods, small population sizes, and the type of stressors. Additional studies using similar stressors and validated stress measures, as well as higher-resolution microbiome analytical approaches, are needed to draw definitive conclusions about the links between stress and the human gut microbiome.

Plain language summary
A sedentary or physically inactive lifestyle significantly contributes to non-communicable diseases such as coronary heart disease, type 2 diabetes and stroke. Wearable activity trackers are low-cost solutions that encourage users to engage in physical activity. This umbrella review of systematic reviews and meta-analyses investigated the benefits of wearable activity trackers in improving physical activity levels and their beneficial effects on physiological and psychosocial outcomes. This umbrella review included thirty-nine systematic reviews, of which twenty-five systematic reviews included meta-analyses of the benefits of wearable trackers on physical activity levels. Results of this umbrella review suggest that wearable trackers increased physical activity levels, especially daily steps count and energy expenditure. The physiological outcomes included improvements in BMI, blood pressure, cholesterol, glycosylated haemoglobin, waist circumference, and body weight. There was also a slight improvement in the quality of life of the participants who used wearable activity trackers. Further robust studies are required to evaluate the effects of wearable trackers on the psychosocial outcomes in people with mental illness. However, healthcare professionals can use the results of this study to understand the impact of wearable trackers on physiological and psychosocial effects in a non-clinical population.
Abstract
Wearable activity trackers offer an appealing, low-cost tool to address physical inactivity. This systematic review of systematic reviews and meta-analyses (umbrella review) aimed to examine the effectiveness of activity trackers for improving physical activity and related physiological and psychosocial outcomes in clinical and non-clinical populations. Seven databases (Embase, MEDLINE, Ovid Emcare, Scopus, SPORTDiscus, the Cochrane Library, and Web of Science) were searched from database inception to April 8, 2021. Systematic reviews of primary studies using activity trackers as interventions and reporting physical activity, physiological, or psychosocial outcomes were eligible for inclusion. In total, 39 systematic reviews and meta-analyses were identified, reporting results from 163 992 participants spanning all age groups, from both healthy and clinical populations. Taken together, the meta-analyses suggested activity trackers improved physical activity (standardised mean difference [SMD] 0·3-0·6), body composition (SMD 0·7-2·0), and fitness (SMD 0·3), equating to approximately 1800 extra steps per day, 40 min per day more walking, and reductions of approximately 1 kg in bodyweight. Effects for other physiological (blood pressure, cholesterol, and glycosylated haemoglobin) and psychosocial (quality of life and pain) outcomes were typically small and often non-significant. Activity trackers appear to be effective at increasing physical activity in a variety of age groups and clinical and non-clinical populations. The benefit is clinically important and is sustained over time. Based on the studies evaluated, there is sufficient evidence to recommend the use of activity trackers.

Plain language summary
COVID-19 has been found to cause neurological manifestations in up to 50% of patients. The aim of this study was to inform future service provision for those who develop long-term neurological symptoms due to COVID-19, as well as exploring the effect of COVID-19 on health professionals’ perceptions towards those with symptoms of functional neurological disorder (FND). This study is a systematic overview of current systematic reviews which included 45 studies in qualitative synthesis. Results show that: - COVID-19 appears to be becoming chronic for some patients, presenting similar neurological symptoms to FND and to chronic fatigue syndrome; - the long-term neurological effects of COVID-19 may impact neurological and wider health care services; - the neurological symptoms seen in COVID-19 may affect health professionals’ perceptions of FND and chronic fatigue syndrome. Authors conclude that there is increasing evidence of the presence of long-COVID symptoms persisting beyond 3 months. Further research is recommended to explore whether the neurological symptoms of COVID-19 will improve acceptance and understanding of FND, or whether this will worsen the experience for those who suffer from FND.
Abstract
AIMS: In response to the rapid spread of COVID-19, this paper provides health professionals with better accessibility to available evidence, summarising findings from a systematic overview of systematic reviews of the neurological symptoms seen in patients with COVID-19. Implications of so-called 'Long Covid' on neurological services and primary care and similarities with other neurological disorders are discussed. METHODS Firstly, a systematic overview of current reviews of neurological symptoms of COVID-19 was conducted. Secondly, the implications of these findings are discussed in relation to the potential effect on neurological services and the similarities in the experience of patients with COVID-19 and those with other neurological disorders. A total of 45 systematic reviews were identified within seven databases, published between 11 April 2020 and 15 October 2020, following a search in June 2020, updated on 20 October 2020. RESULTS The results indicated that COVID-19 exhibits two types of neurological symptoms; life-threatening symptoms such as Guillain-Barre Syndrome (GBS) and encephalitis, and less devastating symptoms such as fatigue and myalgia. Many of these so-called lesser symptoms appear to be emerging as longer-term for some sufferers and have been recently labelled Long Covid. When compared, these less devastating symptoms are very similar to other neurological conditions such as chronic fatigue syndrome (CFS) and functional neurological disorder (FND). CONCLUSION Implications for neurological healthcare services in the United Kingdom (UK) may include longer waiting times and a need for more resources (including more qualified health professionals). There is also a possible change-effect on health professionals' perceptions of other neurological conditions such as CFS and FND. Future research is recommended to explore changes in health professionals' perceptions of neurological symptoms because of COVID-19.

Plain language summary
In response to the Covid-19 pandemic, many individuals have health-related fear of contracting the disease. In some, this has developed into health anxiety (HA) whereby the sufferer is obsessed with contracting or developing a serious illness, impairing their day-to-day functioning. HA is commonplace in adulthood and most research is in adults; however, it is now thought that it can develop in children. This review on HA in adults aimed to identify adaptations needed to ensure diagnosis and interventions are appropriate for children. The review discussed that children may not be diagnosed with HA, as the criteria used for diagnosis may not be age appropriate; HA symptoms in adults may not be the same in children and adolescents. Health-related worries are relatively common in children but may not be diagnosed as HA. The authors then went on to discuss HA in children in the context of Covid-19 and outlined that limited brain development, pre-existing mental health or physical problems and the influence of parent or carer mental health may contribute to its development. Finally, the paper discussed how diagnosis and treatment in adults could be adapted for children, with a strong focus on cognitive behavioural therapy. It was concluded that HA can develop in children and for those individuals an adapted multi-pronged approach to diagnosis and treatment may be of benefit, however more research is needed. This study could be used by healthcare professionals to understand that children can suffer from HA, how it presents itself and possible treatments for children.
Abstract
Health-related fear is a normal and common response in the face of the global pandemic of COVID-19. Children and young people are frequently being exposed to messages about the threat to health, including from the media and authorities. Whilst for most, their anxiety will be proportionate to the threat, for some, existing pre-occupation with physical symptoms and illness will become more problematic. There is a growing body of evidence that health anxiety may occur in childhood, however much of the literature is taken from research using adult samples. This practitioner review aims to give an overview of the assessment and treatment of health-related worries in children and young people in the context of the COVID-19 pandemic. This review is based on the limited existing evidence in this population and the more substantial evidence base for treating health anxiety in adults. We consider the adaptations needed to ensure such interventions are developmentally appropriate.

Plain language summary
The causes of anxiety and depression are unclear, but growing evidence points to a role of the gut microbiota. One possible way that the gut microbiota may have an influence on mental health is through a group of chemical messengers in the brain, known as neurotransmitters. This review summarised the research surrounding neurotransmitters and gut microbiota. The review began by looking at research in animal models and the roles of various neurotransmitters and how they may be influenced by the gut microbiota. The neurotransmitters outlined were serotonin, dopamine, and noradrenaline and it was stated that there is evidence that gut microbiota may be able to influence them alleviating anxiety and/or depression, however there was limited evidence with noradrenaline. It was concluded that there is a close connection between the gut microbiota and anxiety and depression. There is more research needed in humans, as most work has been completed in animal models. This paper could be used by healthcare professionals to understand the role of the gut microbiota in mental health disorders and the importance of gut health in individuals suffering from these.
Abstract
Anxiety and depression are highly prevalent mental illnesses worldwide and have long been thought to be closely associated to neurotransmitter modulation. There is growing evidence indicating that changes in the composition of the gut microbiota are related to mental health including anxiety and depression. In this review, we focus on combining the intestinal microbiota with serotonergic, dopaminergic, and noradrenergic neurotransmission in brain, with special emphasis on the anxiety- and depression-like behaviors in stress-related rodent models. Therefore, we reviewed studies conducted on germ-free rodents, or in animals subjected to microbiota absence using antibiotics, as well as via the usage of probiotics. All the results strongly support that the brain neurotransmitter modulation by gut microbiota is indispensable to the physiopathology of anxiety and depression. However, a lot of work is needed to determine how gut microbiota mediated neurotransmission in human brain has any physiological significance and, if any, how it can be used in therapy. Overall, the gut microbiota provides a novel way to alter neurotransmitter modulation in the brain and treat gut-brain axis diseases, such as anxiety and depression.

Plain language summary
Heart disease, stroke and their associated complications are a leading cause of death worldwide. Factors such as obesity, type 2 diabetes, smoking and inactivity all contribute to heart diseases, however these can be modified. Certain behavioural change strategies have been shown to be effective in reducing these diseases, however the emergence of the use of digital technologies to effect change needs to be better understood. This systematic review and meta-analysis aimed to determine the effectiveness of digital technology to affect change and highlight methods, which may be particularly effective. The results showed that the most researched digital device interventions were cell phones, smart phones, personal computers, and wearables coupled with the internet, SMS, and mobile sensors. Through these methods of delivery benefits were seen in total cholesterol, blood lipid concentrations, physical activity, and diet. However, there were no benefits to body mass index (BMI), blood pressure, blood sugar, alcohol intake, smoking or medication adherence. It was concluded that digital interventions may improve some clinical measures and behaviours, however some remained unaffected highlighting limitations of digital technology to affect change. This study could be used by healthcare professionals to understand that although digital interventions may help to change some aspects of behaviour, other support strategies may need to be employed in challenging cases.
Abstract
BACKGROUND Approximately 50% of cardiovascular disease (CVD) cases are attributable to lifestyle risk factors. Despite widespread education, personal knowledge, and efficacy, many individuals fail to adequately modify these risk factors, even after a cardiovascular event. Digital technology interventions have been suggested as a viable equivalent and potential alternative to conventional cardiac rehabilitation care centers. However, little is known about the clinical effectiveness of these technologies in bringing about behavioral changes in patients with CVD at an individual level. OBJECTIVE The aim of this study is to identify and measure the effectiveness of digital technology (eg, mobile phones, the internet, software applications, wearables, etc) interventions in randomized controlled trials (RCTs) and determine which behavior change constructs are effective at achieving risk factor modification in patients with CVD. METHODS This study is a systematic review and meta-analysis of RCTs designed according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analysis) statement standard. Mixed data from studies extracted from selected research databases and filtered for RCTs only were analyzed using quantitative methods. Outcome hypothesis testing was set at 95% CI and P=.05 for statistical significance. RESULTS Digital interventions were delivered using devices such as cell phones, smartphones, personal computers, and wearables coupled with technologies such as the internet, SMS, software applications, and mobile sensors. Behavioral change constructs such as cognition, follow-up, goal setting, record keeping, perceived benefit, persuasion, socialization, personalization, rewards and incentives, support, and self-management were used. The meta-analyzed effect estimates (mean difference [MD]; standard mean difference [SMD]; and risk ratio [RR]) calculated for outcomes showed benefits in total cholesterol SMD at -0.29 [-0.44, -0.15], P<.001; high-density lipoprotein SMD at -0.09 [-0.19, 0.00], P=.05; low-density lipoprotein SMD at -0.18 [-0.33, -0.04], P=.01; physical activity (PA) SMD at 0.23 [0.11, 0.36], P<.001; physical inactivity (sedentary) RR at 0.54 [0.39, 0.75], P<.001; and diet (food intake) RR at 0.79 [0.66, 0.94], P=.007. Initial effect estimates showed no significant benefit in body mass index (BMI) MD at -0.37 [-1.20, 0.46], P=.38; diastolic blood pressure (BP) SMD at -0.06 [-0.20, 0.08], P=.43; systolic BP SMD at -0.03 [-0.18, 0.13], P=.74; Hemoglobin A1C blood sugar (HbA1c) RR at 1.04 [0.40, 2.70], P=.94; alcohol intake SMD at -0.16 [-1.43, 1.10], P=.80; smoking RR at 0.87 [0.67, 1.13], P=.30; and medication adherence RR at 1.10 [1.00, 1.22], P=.06. CONCLUSIONS Digital interventions may improve healthy behavioral factors (PA, healthy diet, and medication adherence) and are even more potent when used to treat multiple behavioral outcomes (eg, medication adherence plus). However, they did not appear to reduce unhealthy behavioral factors (smoking, alcohol intake, and unhealthy diet) and clinical outcomes (BMI, triglycerides, diastolic and systolic BP, and HbA1c).

The 2019 coronavirus disease (COVID-19), is a public health emergency with serious adverse implications for populations, healthcare systems, and economies globally. The aim of this review was to explore the possible association between ethnicity, incidence and outcomes of COVID-19 using both recent COVID-19 studies and studies of previous pandemics. Findings show that: - ethnic minorities have lower lung function compared to their Caucasian counterparts. - Black, Asian and Minority Ethnics communities are prone to higher rates of cardiovascular disease and are subject to adverse healthcare disparities. - ethnic minorities are disproportionately affected, and experience worse health outcomes compared to other groups. They are also more likely to be socioeconomically disadvantaged compared to white communities. - Africans are at a higher risk of receiving later and more indigent healthcare compared to other ethnic groups. Authors conclude that data on ethnicity should be routinely collected by governments to robustly determine magnitude of association. In addition, governments should also recommend strategies to mitigate risks on minority ethnicities due to socioeconomic disadvantages.
Abstract
The 2019 coronavirus disease is a serious public health emergency, with serious adverse implications for populations, healthcare systems, and economies globally. Recently, concerns have been raised about possible association between ethnicity, incidence and outcomes of COVID-19 arisen from early government data. In this review, we will explore the possible association using both recent COVID-19 studies and studies of previous pandemics. We call for data on ethnicity to be routinely collected by governments, as part of an international collaboration, alongside other patient demographics and further research to robustly determine the magnitude of association. Moreover, governments must learn from previous pandemics and recommended strategies to mitigate risks on minority ethnicities due to socioeconomic disadvantages.

Plain language summary
Food packages with nutrient warnings are increasingly being produced to promote healthier eating. However, better understanding is needed to see how these affect consumer behaviour. This scoping review summarises evidence for randomised control trials on how behaviour is affected by nutrient package warnings and what the trials are assessing to determine this. The results included 22 studies which showed that studies focused on positive outcomes such as attention, comprehension, and behavioural intentions, but not behavioural change, negative effects, or social interactions. Amongst the studies nutrient warnings were attention grabbing, easy to understand, and discouraged buying, however why this is the case was left unexplained. It was concluded that front of package warnings are easy to understand and discouraged buying, however further studies are needed to determine negative effects.
Abstract
Policies that require front-of-package (FoP) nutrient warnings are becoming increasingly common across the globe as a strategy to discourage excess consumption of sugary drinks and ultra-processed food. However, a better understanding of the pathway through which FoP nutrient warnings work, as well as a review of how outcomes being measured in recent studies map onto this pathway, are needed in order to inform policy on the most effective FoP label design for reducing purchases of ultra-processed foods. This scoping review describes a conceptual model for how FoP nutrient warnings affect consumer behavior, examines which of these outcomes are currently being measured, and summarizes evidence from randomized controlled experiments. Twenty-two studies which experimentally tested nutrient warnings against a control label or other labeling systems were included for full-text review. Our conceptual model includes attention; comprehension, cognitive elaboration, and message acceptance; negative affect and risk perception; behavioral intentions, and behavioral response, along with other elements such as external factors and interpersonal communications. We found that many studies focused on outcomes such as attention, comprehension, and behavioral intentions, but considerable gaps in the evidence remain, particularly for intermediary steps on the pathway to behavioral change, such as negative affect and social interactions. FoP nutrient warnings were visually attended to by consumers, easy to understand, helped consumers identify products high in nutrients of concern, and discouraged them from purchasing these products, although other labeling systems were perceived as containing more information and performed better at helping consumers rank the healthfulness of products. More research is needed to understand whether and how nutrient warnings work in the real world to discourage consumer purchases of sugary drinks and ultra-processed food.

Plain language summary
This viewpoint article raises awareness of the threat of COVID-19 poses to psychiatric patients who are in mental health hospitals. Those patients appear to have a much elevated mortality rate and are potentially more vulnerable to the effects of panic/anxiety due to the pandemic. Their lifestyle choices, influenced by fears about the virus, may also have a negative effect on their immunity. The article also raises the issue of the effects the pandemic and associated changes to day-to-day life can have on the mental and general health of the rest of the population, and in particular to mental health professionals, whose ability to care for their psychiatric patients may be impaired. The authors also briefly discuss the psychological and immunological mechanisms that connect our mental state to the ability of our immune system to fight infections, and the impact of our lifestyles and environments. To summarise they state that infected patients, uninfected quarantined individuals and medical professionals all require mental health supporting strategies, and that epidemiological studies of potential long-term psychiatric consequences are essential.
Abstract
The worldwide outbreak of coronavirus disease 2019 (COVID-19) raises concerns of widespread panic and anxiety in individuals subjected to the real or perceived threat of the virus. Compared to general populations, patients who are institutionalized in a closed unit are also very vulnerable to COVID-19 infection and complications. This crisis touched on difficult issues of not only psychiatric care and ethics, but also psychological impacts to psychiatric care givers. In this Viewpoint, we address both physical and biopsychosocial aspects of this infection, as well as the psychoneuroimmunity of preventive strategies of healthy lifestyle, regular exercise, balanced nutrition, quality sleep and a strong connection with people. Social distancing and wearing masks might help us from pathogen exposure, yet such these measures also prevent us from expressing compassion and friendliness. Therefore, all forms of psychological support should be routinely implemented not only to consider psychological resilience but also to enhance psychoneuroimmunity against COVID-19.

Plain language summary
Treating severe and complex obesity requires specialist multi-professional teams for assessment, management and optimizing patients’ health outcomes. The aim of this study was to review existing evidence for defining commissioning and delivery of primary or secondary care weight assessment and management clinics to patients needing specialist care for severe and complex obesity. Twenty-two UK royal colleges and professional organizations were invited to develop the guidance revision according to the NICE-accreditation process. Fifty references were included in the final report. The following additions have been identified as new emergent developments to be included in the guidance: - multi-disciplinary team pathways for children/adolescent patients and their transition to adult care, and - anaesthetic assessment and recommendations for ongoing shared care with general practitioners, as a chronic disease management pathway. Authors indicate that the Guidance Development Group recommends the use of the NICE-accredited commissioning guidance as healthcare services in different countries develop services to manage patients with severe and complex obesity.
Abstract
The challenge of managing the epidemic of patients with severe and complex obesity disease in secondary care is largely unmet. In England, the National Institute of Health and Care Excellence and the National Health Service England have published guidance on the provision of specialist (non-surgical) weight management services. We have undertaken a systematic review of 'what evidence exists for what should happen in/commissioning of: primary or secondary care weight assessment and management clinics in patients needing specialist care for severe and complex obesity?' using an accredited methodology to produce a model for organization of multidisciplinary team clinics that could be developed in every healthcare system, as an update to a previous review. Additions to the previous guidance were multidisciplinary team pathways for children/adolescent patients and their transition to adult care, anaesthetic assessment and recommendations for ongoing shared care with general practitioners, as a chronic disease management pathway.
