Prevalence of Vitamin D Deficiency and Its Relationship with Clinical Outcomes in Patients with Fibromyalgia: a Systematic Review of the Literature

Fibromyalgia is a debilitating chronic condition which poses a therapeutic challenge to the clinician. With a large backlog in patient flow subsequent to the COVID-19 pandemic and rising numbers of patients with post-acute sequelae of COVID-19 (PASC) presenting with fibromyalgia-like clinical features, there is an increasingly pressing need to identify broad cost-effective interventions. Low levels of vitamin D have previously been reported in patients with fibromyalgia, though any causative link has been difficult to establish. A systematic literature review on the association between vitamin D deficiency and fibromyalgia was performed examining retrospective evidence both for and against an association between vitamin D deficiency (VDD) and fibromyalgia and evaluating the therapeutic benefit from supplementation. A group of six studies were selected based on relevance, use of controls, quality of research and citations. Four primary studies assessing the prevalence of VDD in fibromyalgia patients versus controls were evaluated with a total 3,496 subjects. Three included females only and one larger study assessed males. Two (n = 313) concluded the presence of a statistically significant association, and two (n = 161) found none. Two randomised controlled trials assessing the effect of vitamin D supplementation in a total of 80 subjects found conflicting results, with pain reduction in one and none in the other. It is likely there exists an association between VDD deficiency and fibromyalgia in a large subset of patients, although establishing primary causation is difficult. There is a need for larger randomised controlled trial designs with more effective comparison with healthy subjects and control for confounding factors. Given VDD is a major problem in the general population, we recommend supplementation be recommended by healthcare professionals to fibromyalgia patients for the purpose of maintaining bone health given their potentially increased susceptibility to developing deficiency and its sequelae.

Symptoms of Survivors of Pediatric Hematopoietic Stem Cell Transplant by Age, Sex, and Transplant Type

Purpose: The purpose of this study was to describe symptoms experienced by survivors of pediatric hematopoietic stem cell transplant (HSCT), and demographic and treatment-factors associated with ongoing symptomology. Methods: Fifty pediatric survivors completed a cross-sectional pilot study. Questionnaires were administered online via REDCap to assess symptoms experienced in the last week. Survivors also consented to a medical record chart review. Results: Survivors were on average 5.4 years post-HSCT (range 1.1 to 9 years), male (58%), and Caucasian (80%) who received an allogeneic HSCT (92%). The most commonly reported symptoms were difficulty concentrating (42.5%), pain (38%), worry (38%), nervousness (37.5%), and lack of energy/fatigue (34%). Survivors reported up to 14 symptoms, with 90% of the sample experiencing at least one symptom in the previous week. Average number of symptoms varied by age group between 2.1 (8–9 years) and 6.8 (18 and older). Age and female gender were associated with higher levels of fatigue. Conclusions: The majority of survivors experienced at least one symptom in the previous week. Neuropsychological symptoms and pain endure well into survivorship that can influence outcomes such as function and health-related quality of life (HRQOL). Research is needed on biological mechanisms of ongoing symptomology, effective interventions to prevent or mitigate symptoms, and the impact of symptoms on patient outcomes including daily functioning and HRQOL. Implications Survivors of pediatric HSCT continued to experience symptoms for up to nine years. Survivors should be frequently screened for symptoms, as symptoms may affect function, learning/employment outcomes, and HRQOL.

The burden of diarrhea, etiologies, and risk factors in India from 1990 to 2019: evidence from the global burden of disease study

Background This study aims to measure the burden of diarrhea in India and analyze the trend of mortality associated with it for the past 30 years. We also intend to find the prevailing etiology and risk factors associated with diarrheal mortality in India. Methods The study has used the latest round of Global Burden of Disease (GBD) study-2019. GBD data is available across age groups and gender-wise over the period from 1990 to 2019. The study has identified 13 etiologies for the cause of diarrhea deaths and 20 risk factors to analyze the burden of disease. Results Our study shows, childhood diarrhea has declined over the years significantly, yet contributes to a larger share of DALYs associated with the disease. Among all the death cases of Diarrhea, in 2019, the most prevalent disease-causing pathogen is found to be Campylobacter. But Adenovirus is the major contributor to childhood diarrheal deaths. Though the burden of diarrhea is declining over the period, still there is a need to progress the interventions to prevent and control diarrhea rapidly to avoid the huge number of deaths and disabilities experienced in India. Conclusions Consumption of safe and clean water, proper sanitation facility in every household, required nutrition intake by mother and child, safe breastfeeding and stool disposal practices and careful case management, rotavirus vaccination are some of the effective interventions to be implemented all over the country. Further, evidence-based policies should be made and implemented to sustain diarrhea prevention programs.

Hybrid simulation modelling of networks of heterogeneous care homes and the inter-facility spread of Covid-19 by sharing staff

Although system dynamics [SD] and agent-based modelling [ABM] have individually served as effective tools to understand the Covid-19 dynamics, combining these methods in a hybrid simulation model can help address Covid-19 questions and study systems and settings that are difficult to study with a single approach. To examine the spread and outbreak of Covid-19 across multiple care homes via bank/agency staff and evaluate the effectiveness of interventions targeting this group, we develop an integrated hybrid simulation model combining the advantages of SD and ABM. We also demonstrate how we use several approaches adapted from both SD and ABM practices to build confidence in this model in response to the lack of systematic approaches to validate hybrid models. Our modelling results show that the risk of infection for residents in care homes using bank/agency staff was significantly higher than those not using bank/agency staff (Relative risk [RR] 2.65, 95% CI 2.57–2.72). Bank/agency staff working across several care homes had a higher risk of infection compared with permanent staff working in a single care home (RR 1.55, 95%CI 1.52–1.58). The RR of infection for residents is negatively correlated to bank/agency staff’s adherence to weekly PCR testing. Within a network of heterogeneous care homes, using bank/agency staff had the most impact on care homes with lower intra-facility transmission risks, higher staff-to-resident ratio, and smaller size. Forming bubbles of care homes had no or limited impact on the spread of Covid-19. This modelling study has implications for policy makers considering developing effective interventions targeting staff working across care homes during the ongoing and future pandemics.

Challenges and Attitude towards Research among Physicians of Bangladesh: A Cross Sectional Questionnaire Survey.

In the history of human civilization, research has played a significant role. There is no doubt that meeting the challenges of the 21st century will be tough if we are not world leaders in science and technology. The objective of this study was to assess physicians' attitude about research and the challenges they confront when doing research. From July to December 2020, a cross-sectional questionnaire survey was performed among physicians in Bangladesh. The questionnaire poll had 626 responses in total. There were 55.6 % female physicians and 44.4% male physicians among them. The majority of physicians (87.6%) felt that conducting research is critical to become a specialist. Research methodology training at the medical colleges are extremely beneficial, according to a substantial percentage of physicians (72.2%). Research methodology should be included in undergraduate curriculum, according to 89% of physicians. Research is beneficial as it aids critical thinking and policy implementation, according to almost all respondents (96.7%). The majority of respondents cited insufficient research training (92%), insufficient funding (92.2%), insufficient time (61%), insufficient familiarity with statistical analysis (88%), insufficient skill to design and conduct a research project and write a scientific paper (90%), as barriers to research. Priority on teaching and clinical practices over research and lack of interest to do research also mentioned by 93.3% and 61% responded respectively. Consequently, this study identified challenges and attitude of physicians towards research. This finding will guide for further studies to find out effective interventions to address the obstacles raised by research participants.

The Relationship Between Gender Self-Stereotyping and Life Satisfaction: The Mediation Role of Relational Self-Esteem and Personal Self-Esteem

Individuals voluntarily internalize gender stereotypes and present personality characteristics and behaviors that conform to gender role requirements. The aim of the current study was to explore the reasons people internalize gender stereotypes. We conducted surveys with 317 college students in China to examine the relationship between gender self-stereotyping and life satisfaction. We also analyzed the mediating roles of relational self-esteem (RSE) and personal self-esteem (PSE) and the moderation role of gender. The results of path analysis showed that gender self-stereotyping directly affected life satisfaction and indirectly affected life satisfaction through RSE and PSE in a serial pattern; however, the serial mediation model was only significant in the male sample. Higher gender self-stereotyping was associated with male participants’ higher level of RSE and PSE and further correlated with higher life satisfaction. This study addressed the questions: “What are the benefits of gender self-stereotyping?” and “What are the major barriers to counter-stereotyping?” The results enrich our understanding of these issues, especially relative to the collectivist culture in China, and may be used to create more effective interventions to help people break through the stereotypes.

Neuromuscular Excercise in Children with Down Syndrome. A Systematic Review

Objective to evaluate the effects of neuromuscular exercise, specifying the parameters and characteristics of effective interventions to improve balance, muscle strength and flexibility in children with DS between the ages of 4 and 18 years. Data Sources: A search was carried out on PubMed, PEDro, EMBASE, SCIELO, Lilacs, Cochrane library. Study Selection: The search yielded 1384 eligible articles. Randomized clinical trials were selected, and that would have reported the effectiveness in the outcomes. Data Extraction: The methodology and results of the studies were critically appraised in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes guidelines. Data Synthesis: Ten studies were included. The interventions included mechanotherapy, vibration, and use of different unstable surfaces. The exercise frequency ranged from three days to five days a week, and the duration of each session was between six and 15 minutes. The frequency was between two and three times a week for 6 and 12 weeks and the intensity was between 60% and 80% of maximum resistance (MR). Conclusion neuromuscular exercise appears to be effective for the improvement of both lower limb and chest muscle strength and balance in children over 8 years of age.

Wider, faster, more: Re-envisioning the treatment and research of depression to address its public health burden in the United States

Depression and other internalizing disorder symptoms are leading causes of disability in theUnited States. Although there are effective interventions, the burden of disability attributableto internalizing disorder symptoms is not decreasing. I review clinical and epidemiological datato identify solutions to the public health burden of internalizing disorder symptoms. Contemporary research efforts have a focus on treatment development and the identification of biomarkers of response. However, these solutions are not scalable because internalizing disorders are much more common than usually appreciated and there are substantial disparities in access to mental health care. Improving the dissemination of individual interventions may also be of limited value given data suggesting that high rates of symptom remission can only be achieved with multiple (e.g., 4-10) treatment steps. The logic of stepped care approaches for internalizing disorders is well-supported by these data, but initial treatments likely should be low-intensity and “stepping up” should occur more quickly than usually done in most trials. Efforts that promise to make an impact in the public health burden of internalizing disorder symptoms need to consider their high prevalence and heterogeneity in the level of care as well as in the mechanisms that treatments may need to engage.

Targeting Epigenetic Mechanisms in Vascular Aging

Environment, diseases, lack of exercise, and aged tendency of population have becoming crucial factors that induce vascular aging. Vascular aging is unmodifiable risk factor for diseases like diabetes, hypertension, atherosclerosis, and hyperlipidemia. Effective interventions to combat this vascular function decline is becoming increasingly urgent as the rising hospitalization rate caused by vascular aging-related diseases. Fortunately, recent transformative omics approaches have enabled us to examine vascular aging mechanisms at unprecedented levels and precision, which make our understanding of slowing down or reversing vascular aging become possible. Epigenetic viz. DNA methylation, histone modifications, and non-coding RNA-based mechanisms, is a hallmark of vascular aging, its deregulation leads to aberrant transcription changes in tissues. Epigenetics mechanisms by mediating covalent modifications to DNA and histone proteins, consequently, influence the sensitivity and activities of signaling pathways in cells and tissues. A growing body of evidence supports correlations between epigenetic changes and vascular aging. In this article, we will provide a comprehensive overview of epigenetic changes associated with vascular aging based on the recent findings with a focus on molecular mechanisms of action, strategies to reverse epigenetic changes, and future perspectives.
