Does the quality of our diet during early life impact our long-term mental health? Accumulating evidence suggests that nutrition interacts with our genes and that there is a strong association between the quality of diet and mental health throughout life. Environmental influences such as maternal diet during pregnancy or offspring diet have been shown to cause epigenetic changes during critical periods of development, such as chemical modifications of DNA or histones by methylation for the regulation of gene expression. One-carbon metabolism, which consists of the folate and methionine cycles, is influenced by the diet and generates S-Adenosylmethinoine (SAM), the main methyl donor for methylation reactions such as DNA and histone methylation. This review provides current knowledge on how the levels of one-carbon metabolism associated micronutrients such as choline, betaine, folate, methionine and B vitamins that play a role in brain function can impact our well-being and mental health across the lifespan. Micronutrients that act as methyl donors for SAM formation could affect global or gene methylation, altering gene expression and phenotype. Strategies should then be adopted to better understand how these nutrients work and their impact at different stages of development to provide individualized dietary recommendations for better mental health outcomes.

Folate and choline are water-soluble micronutrients that serve as methyl donors in the conversion of homocysteine to methionine. Inadequacy of these nutrients can disturb one-carbon metabolism as evidenced by alterations in circulating folate and/or plasma homocysteine. Among common genetic variants that reside in genes regulating folate absorptive and metabolic processes, homozygosity for the MTHFR 677C > T variant has consistently been shown to have robust effects on status markers. This paper will review the impact of genetic variants in folate-metabolizing genes on folate and choline bioefficacy. Nutrient-gene and gene-gene interactions will be considered along with the need to account for these genetic variants when updating dietary folate and choline recommendations.

Abstract Background Surgery is the cornerstone of esophageal cancer treatment but remains burdened with significant postoperative changes of gastrointestinal function and quality of life. Purpose The aim of this narrative review is to assess and summarize the current knowledge on postoperative functional syndromes and quality of life after esophagectomy for cancer, and to provide orientation for the reader in the challenging field of functional aftercare. Conclusions Post-esophagectomy syndromes include various conditions such as dysphagia, reflux, delayed gastric emptying, dumping syndrome, weight loss, and chronic diarrhea. Clinical pictures and individual expressions are highly variable and may be extremely distressing for those affected. Therefore, in addition to a mostly well-coordinated oncological follow-up, we strongly emphasize the need for regular monitoring of physical well-being and gastrointestinal function. The prerequisite for an effective functional aftercare covering the whole spectrum of postoperative syndromes is a comprehensive knowledge of the pathophysiological background. As functional conditions often require a complex diagnostic workup and long-term therapy, close interdisciplinary cooperation with radiologists, gastroenterologists, oncologists, and specialized nutritional counseling is imperative for successful management.

Sleep disorders, despite being very frequent in adults with Down syndrome (DS), are often overlooked due to a lack of awareness by families and physicians and the absence of specific clinical sleep guidelines. Untreated sleep disorders have a negative impact on physical and mental health, behavior, and cognitive performance. Growing evidence suggests that sleep disruption may also accelerate the progression to symptomatic Alzheimer’s disease (AD) in this population. It is therefore imperative to have a better understanding of the sleep disorders associated with DS in order to treat them, and in doing so, improve cognition and quality of life, and prevent related comorbidities. This paper reviews the current knowledge of the main sleep disorders in adults with DS, including evaluation and management. It highlights the existing gaps in knowledge and discusses future directions to achieve earlier diagnosis and better treatment of sleep disorders most frequently found in this population.

AbstractHematopoiesis requires finely tuned regulation of gene expression at each stage of development. The regulation of gene transcription involves not only individual transcription factors (TFs) but also transcription complexes (TCs) composed of transcription factor(s) and multisubunit cofactors. In their normal compositions, TCs orchestrate lineage-specific patterns of gene expression and ensure the production of the correct proportions of individual cell lineages during hematopoiesis. The integration of posttranslational and conformational modifications in the chromatin landscape, nucleosomes, histones and interacting components via the cofactor–TF interplay is critical to optimal TF activity. Mutations or translocations of cofactor genes are expected to alter cofactor–TF interactions, which may be causative for the pathogenesis of various hematologic disorders. Blocking TF oncogenic activity in hematologic disorders through targeting cofactors in aberrant complexes has been an exciting therapeutic strategy. In this review, we summarize the current knowledge regarding the models and functions of cofactor–TF interplay in physiological hematopoiesis and highlight their implications in the etiology of hematological malignancies. This review presents a deep insight into the physiological and pathological implications of transcription machinery in the blood system.

ObjectiveTo examine the extent, nature and quality of literature on the impact of the COVID-19 pandemic on the mental health of imprisoned people and prison staff.DesignScoping review.Data sourcesPubMed, Embase, CINAHL, Global Health, Cochrane, PsycINFO, PsychExtra, Web of Science and Scopus were searched for any paper from 2019 onwards that focused on the mental health impact of COVID-19 on imprisoned people and prison staff. A grey literature search focused on international and government sources and professional bodies representing healthcare, public health and prison staff was also performed. We also performed hand searching of the reference lists of included studies.Eligibility criteria for selection of studiesAll papers, regardless of study design, were included if they examined the mental health of imprisoned people or prison staff specifically during the COVID-19 pandemic. Imprisoned people could be of any age and from any countries. All languages were included. Two independent reviewers quality assessed appropriate papers.ResultsOf 647 articles found, 83 were eligible for inclusion, the majority (58%) of which were opinion pieces. The articles focused on the challenges to prisoner mental health. Fear of COVID-19, the impact of isolation, discontinuation of prison visits and reduced mental health services were all likely to have an adverse effect on the mental well-being of imprisoned people. The limited research and poor quality of articles included mean that the findings are not conclusive. However, they suggest a significant adverse impact on the mental health and well-being of those who live and work in prisons.ConclusionsIt is key to address the mental health impacts of the pandemic on people who live and work in prisons. These findings are discussed in terms of implications for getting the balance between infection control imperatives and the fundamental human rights of prison populations.

Parents from individualist cultures (those focused on autonomy of individuals; that is, Australian) may view their autistic children differently compared to parents from collectivist cultures (where community needs are valued over an individual’s, that is, South-East Asian cultures). As most research on autism and parenting has been undertaken in Western individualist cultures, knowledge of parenting beliefs and mental health within collectivist cultures is lacking. We compared the mental health, quality of life, well-being and parenting sense of competency between families raising an autistic child from two groups: 97 Australian parents and 58 parents from South-East Asian backgrounds. Children from both groups were receiving the same community-based early intervention. No group differences were found on the measures of mental health but, when compared to Australian parents, parents from South-East Asian backgrounds reported higher well-being and less impact on their quality of life resulting from their child’s autism-specific difficulties. Furthermore, a positive association between well-being and quality of life was only observed for South-East Asian parents. Hence, the views of, and responses to, disability for South-East Asian parents may act as a protective factor promoting well-being. This novel research indicates that culture plays a role in parenting autistic children and highlights the need to accurately capture cultural background information in research. Lay abstract We know that parents of autistic children experience poorer mental health and lower well-being than parents of non-autistic children. We also know that poorer mental health among parents of autistic children has been observed across different cultures. Most research focuses on Western cultures, so we know little about parental mental health and well-being of parents from different cultural backgrounds; yet, it is likely that cultural background contributes to how parents view their child’s condition and respond to the diagnosis. Here, we compared mental health, quality of life and well-being between families raising an autistic child from Australian backgrounds to families from South-East Asian backgrounds. All children in the current study were receiving the same community-based early intervention. When compared to the general population, parents had poorer mental health overall, but there were no differences between the two groups of parents. However, parents from South-East Asian backgrounds reported higher well-being and fewer difficulties associated with their child’s autism. These findings suggest that cultural background likely influences not only parent’s view of, and response to, their child’s autism, but also their own sense of well-being. As researchers and clinicians working with families of autistic children, we should more explicitly consider family’s cultural background within our work.

The onset of the infectious disease Covid19 originating in Wuhan, China, took over the world in December 2019 and was declared a pandemic in January 2020.  Empirical evidence resulting from relevant research illustrated that the effects of the pandemic itself but also of the strict measures to contain the spread of the virus on the mental health and well-being of affected populations were just as unanticipated as the pandemic itself. Data led to the identification of six idioms of distress: (1) Demoralization and pessimism towards the future, (2) anguish and stress, (3) self-depreciation, (4) social withdrawal and isolation, (5) somatization, (6) withdrawal into oneself. Our research explores the psychological impact of the Covid19 pandemic on college students and their quality of life. The study took place in Cyprus with 356 young participants, whereas 256 were female (72%) and 100 were male (28%). They all completed the General Health Questionnaire-28 and the Life Satisfaction Inventory (LSI). The present study's findings revealed that six factors, including residence without family, the deterioration of the financial situation of the family, the loss of employment, the deterioration of social relationships, young age, and gender, have significantly affected in a negative way the mental health and quality of life of young people. Research findings revealed that the strict lockdown and physical/social isolation measures had a significant adverse effect on our sample, whereas participants showed increased symptoms of anxiety and insomnia, social dysfunction, and somatization. Young adults who lost their jobs during the pandemic or had a significant decrease in their family income, and students who stayed away from their families, experienced a negative impact on their quality of life and had to cope with more mental health problems.

Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity. Mental health refers to our overall psychological well-being. It includes the way we feel about our self, the quality of our relationships, and our ability to manage our feelings and deal with difficulties. Good mental health isn’t just the absence of mental health problems. People who are emotionally or mentally healthy are in control of their emotions and their behavior. They are able to handle life’s challenges, build strong relationships, and recover from setbacks. Positive mental health is a state of well-being in which we realize our abilities, can cope with life’s normal stresses, and can work regularly and productively. Physical health means a good body health, which is healthy because of regular physical activity, good nutrition, and adequate rest. Physical health can be determined by considering someone’s height/weight ratio, their Body Mass Index. Another term for physical health is physical wellbeing. Physical wellbeing is defined as something a person can achieve by developing all health-related components of his/her lifestyle. It can be concluded that mental and physical health is fundamentally linked. There are multiple associations between mental health and chronic physical conditions that significantly impact people’s quality of life. Just as physical fitness helps our bodies to stay strong, mental fitness helps us to achieve and sustain a state of good mental health. When we are mentally healthy, we enjoy our life and environment, and the people in it.

Susceptibility to complex pathological conditions such as obesity, type 2 diabetes and cardiovascular disease is highly variable among individuals and arises from specific changes in gene expression in combination with external factors. The regulation of gene expression is determined by genetic variation (SNPs) and epigenetic marks that are influenced by environmental factors. Aging is a major risk factor for many multifactorial diseases and is increasingly associated with changes in DNA methylation, leading to differences in gene expression. Four and a half LIM domains 2 (FHL2) is a key regulator of intracellular signal transduction pathways and the FHL2 gene is consistently found as one of the top hyper-methylated genes upon aging. Remarkably, FHL2 expression increases with methylation. This was demonstrated in relevant metabolic tissues: white adipose tissue, pancreatic β-cells, and skeletal muscle. In this review, we provide an overview of the current knowledge on regulation of FHL2 by genetic variation and epigenetic DNA modification, and the potential consequences for age-related complex multifactorial diseases.

This study aimed to test a model that hypothesized that the compassionate coach, as perceived by the athletes, has an impact on athlete-related social safeness and psychological health, through shame and self-criticism. The sample comprised 270 Portuguese adult athletes, who practiced different competitive sports. The path analysis results confirmed the adequacy of the proposed model, which explained 45% of the psychological health’s variance. Results demonstrated that athletes who perceive their coaches as more compassionate tend to present higher levels of social safeness (feelings of belonging to the team) and of psychological health, through lower levels of shame and self-criticism. These novel findings suggest the importance of the adoption of supportive, warm, safe, and compassionate attitudes from coaches in athletes’ mental health. This study also offers important insights by suggesting that feelings of acceptance and connectedness in team relationships may be at the root of athletes’ emotional processes and well-being.
