Much of the evidence on the relationship between stress, lifestyle and other physical and mental health outcomes comes from studies conducted in high-income countries. Thus, there is a need for research among populations of low- and middle-income settings.

The aim of this manuscript was to measure levels of stress, as well as to identify associated factors and health consequences of high stress level.

This was a population-based cross-sectional study, carried out in 2016, with adults aged 18 years or older in a municipality in southern Brazil. Sampling strategy was conducted in two stages based on census tracts. Stress level was measured through Perceived Stress Scale (PSS-14). The impact of high stress level on each outcome was assessed by etiologic fraction (EF).

Groups most stressed were females (PR=1.51, 95%CI 1.25-1.81), younger (PR=1.76, 95%CI 1.26-2.46) and middle-aged individuals (PR=1.60, 95%CI 1.17-2.19), with lower schooling (PR=1.56, 95%CI 1.20-2.02), physically inactive (PR=1.51, 95%CI 1.20-1.91), with three or more hours of television time per day (PR=1.29, 95%CI 1.12-1.50), and with food insecurity (PR=1.44, 95%CI 1.19-175). Possible consequences of high stress level were regular or poor self-perception of health (EF=29.6%), poor or very poor sleep quality (EF=17.3%), lower quality of life (EF=45.6%), sadness (EF=24.2%), and depressive symptoms (EF=35.8%).

Stress plays an important role in several domains of health. Both public policies that target reduction of inequalities and specific stress-management interventions can reduce stress levels of population, therefore decreasing the burden of other negative physical and mental health outcomes related to stress.

Workplace silence impedes productivity, job satisfaction and retention, key issues for the hospital workforce worldwide. It can have a negative effect on patient outcomes and safety and human resources in healthcare organisations. This study aims to examine factors that influence workplace silence among hospital doctors in Ireland.

A national, cross-sectional, online survey of hospital doctors in Ireland was conducted in October-November 2019; 1,070 hospital doctors responded. This paper focuses on responses to the question "If you had concerns about your working conditions, would you raise them?". In total, 227 hospital doctor respondents (25%) stated that they would not raise concerns about their working conditions. Qualitative thematic analysis was carried out on free-text responses to explore why these doctors choose to opt for silence regarding their working conditions.

Reputational risk, lack of energy and time, a perceived inability to effect change and cultural norms all discourage doctors from raising concerns about working conditions. Apathy arose as change to working conditions was perceived as highly unlikely. In turn, this had scope to lead to neglect and exit. Voice was seen as risky for some respondents, who feared that complaining could damage their career prospects and workplace relationships.

This study highlights the systemic, cultural and practical issues that pressure hospital doctors in Ireland to opt for silence around working conditions. https://www.selleckchem.com/products/cc-885.html It adds to the literature on workplace silence and voice within the medical profession and provides a framework for comparative analysis of doctors' silence and voice in other settings.

The goal of this exploratory study was to evaluate the effects of an exercise intervention - progressive resistance training (PRT) on the metabolome of people with MS (pwMS) and to link these to changes in clinical outcomes.

14 pwMS with EDSS <4.0 and 13 age- and sex-matched healthy controls completed a 12-week in-person PRT exercise intervention. Outcome measures included plasma metabolomics analysis, cardiovascular fitness tests, EDSS, timed 25-foot walk (T25FW), six-minute walk test (6MWT), hip strength, and modified fatigue impact scale (MFIS). We identified changes in the metabolome with PRT intervention in both groups using individual metabolite abundance and weighted correlation network defined metabolite module eigenvalues and then examined correlations in changes in metabolite modules with changes in various clinical outcomes.

In both groups PRT intervention improved hip strength, distance walked in 6WMT, speed of walking, while fatigue (MFIS) was improved in pwMS. Fatty acid, phospholipid, and sex steroid metabolism were significantly altered by PRT in pwMS but not in controls. Changes in fatigue (MFIS score) were strongly inversely correlated and hip strength was moderately correlated with change in sex steroid metabolite module in pwMS. A similar relationship was noted between change in dehydroepiandrosterone sulfate abundance (sex steroid metabolite) and fatigue in pwMS. We also noted an inverse correlation between changes in fatty acid metabolism and cardiovascular fitness in pwMS.

PRT-induced metabolic changes may underlie improved clinical parameters in pwMS and may warrant investigation as potential therapeutic targets in future studies.

While rheumatoid arthritis (RA) and its treatments are associated with an increased infection risk, it remains unclear whether these factors impact the risk or severity of COVID-19.

We conducted a matched cohort study using national Veterans Affairs data. Among non-deceased individuals on January 1, 2020 who received VA care in 2019, we matched RA to non-RA patients (11) on age, sex, and VA site. COVID-19 and severe COVID-19 (hospitalization or death) were obtained from a national VA COVID-19 surveillance database through December 10, 2020. We used multivariable Cox models to compare the risk of COVID-19 and COVID-19 hospitalization or death after adjusting for demographics, comorbidities, health behaviors, and county level COVID-19 incidence rates.

RA and non-RA patients (n=33,886 each) were male predominant (84.5%) and had a mean age of 67.8 years. During follow-up, there were 1,503 COVID-19 diagnoses, 388 severe COVID-19 cases, and 228 non-COVID-19 related deaths. After multivariable adjustment, RA was associated with a higher risk of COVID-19 (hazard ratio [HR] 1.25 [95% confidence interval 1.13, 1.39]) and COVID-19 hospitalization or death (HR 1.35 [1.10, 1.66]). DMARDs and prednisone, but not RA autoantibody seropositivity, as well as black race, Hispanic ethnicity, and several chronic conditions were associated with COVID-19 and COVID-19 hospitalization or death.

Patients with RA are at higher risk for COVID-19 and COVID-19 hospitalization or death than non-RA. With a COVID-19 risk that approaches other recognized chronic conditions, these findings suggest RA patients should be prioritized for COVID-19 prevention and management.

Provision of tailored treatment options accounting for individual and family needs, preferences, and capacity may encourage adolescents with obesity to seek treatment, and/or improve treatment outcomes. Delivered by trained health care professionals, novel dietary interventions may have utility for adolescents not responding to conventional diets, adolescents with comorbidities or severe obesity, and/or when rapid or substantial weight loss is required. This review describes current evidence and clinical considerations relating to the use of very low energy diets, low carbohydrate diets, and intermittent energy restriction in the treatment of adolescent obesity. Emerging evidence on the use of these novel dietary interventions demonstrates short-term weight-related and cardiometabolic improvements. While the evidence is encouraging, and no serious adverse effects have been reported, monitoring of intervention safety is essential. Considerations for health care professionals providing care to adolescents include nutritional adequacy, psychosocial health and social relationships during the intervention. Furthermore, long-term weight-related, cardiometabolic and psychological health outcomes of these dietary interventions are not well understood. Large randomised controlled trials are warranted to inform clinical practice and future guidelines for the use of novel dietary interventions in adolescents with obesity.The most common cancer diagnosis in female population is breast cancer, which affects every year about 2.0 million women worldwide. In recent years, significant progress has been made in oncological therapy, in systemic treatment, and in radiotherapy of breast cancer. Unfortunately, the improvement in the effectiveness of oncological treatment and prolonging patients' life span is associated with more frequent occurrence of organ complications, which are side effects of this treatment. Current recommendations suggest a periodic monitoring of the cardiovascular system in course of oncological treatment. The monitoring includes the assessment of occurrence of risk factors for cardiovascular diseases in combination with the evaluation of the left ventricular systolic function using echocardiography and electrocardiography as well as with the analysis of the concentration of cardiac biomarkers. The aim of this review was critical assessment of the breast cancer therapy cardiotoxicity and the analysis of methods its detections. The new cardio-specific biomarkers in serum, the development of modern imaging techniques (Global Longitudinal Strain and Three-Dimensional Left Ventricular Ejection Fraction) and genotyping, and especially their combined use, may become a useful tool for identifying patients at risk of developing cardiotoxicity, who require further cardiovascular monitoring or cardioprotective therapy.
Skeletal muscle (SM) alterations contribute to exercise intolerance in heart failure patients with preserved (HFpEF) or reduced (HFrEF) left ventricular ejection fraction (LVEF). Protein degradation via the ubiquitin-proteasome-system (UPS), nuclear apoptosis, and reduced mitochondrial energy supply is associated with SM weakness in HFrEF. These mechanisms are incompletely studied in HFpEF, and a direct comparison between these groups is missing.

Patients with HFpEF (LVEF≥50%, septal E/e'>15 or >8 and NT-proBNP>220pg/mL, n=20), HFrEF (LVEF≤35%, n=20) and sedentary control subjects (Con, n=12) were studied. Inflammatory markers were measured in serum, and markers of the UPS, nuclear apoptosis, and energy metabolism were determined in percutaneous SM biopsies. Both HFpEF and HFrEF showed increased proteolysis (MuRF-1 protein expression, ubiquitination, and proteasome activity) with proteasome activity significantly related to interleukin-6. Proteolysis was more pronounced in patients with lower exercise capacity as indicated by peak oxygen uptake in per cent predicted below the median.
