18 to 1.53) compared with "not supervised" areas. Organisation and supervision might influence PA choices and PA levels of children in the primary school playground. Further investigation is required to explore different playgrounds settings, and context and gender preferences.The Minority Stress Model has proposed that connectedness to a specific minority community may be a protective factor for stigmatized groups. This study evaluated the mediational role of connectedness with the gay men's and lesbian women's community on the relationship between two minority stressors (internalized homophobia and perceived sexual stigma) with anxiety-depressive symptomatology and life satisfaction. The sample consisted of 467 Chilean self-identified as gay men (57%) and lesbian women (43%). Results revealed that the two minority stressors were associated with anxiety-depressive symptomatology, but only internalized homophobia was associated with life satisfaction. The mediation hypothesis was partially supported by the relationship between internalized homophobia and life satisfaction. Unexpectedly, we found a negative association between connectedness with the gay men's and lesbian women's community and life satisfaction. This finding introduces a view that contrasts with the literature, which proposes that connectedness with the specific community would be a protective factor against sexual stigma.Family caregivers faced unprecedented circumstances and experienced increased levels of stress during the COVID-19 pandemic. Resourcefulness can minimize the effect of stress on health outcomes. The purpose of this study was to examine the associations between caregiving stress during the pandemic, resourcefulness, and self-rated health and assess the mediating effect of resourcefulness. A convenience sample of 70 family caregivers of adults with chronic and/or disabling conditions was recruited using social media groups and professional networking platforms. Data were collected using an online survey and analyzed using linear regression. Mediation analysis was conducted using the PROCESS macro. Higher levels of caregiving stress during the pandemic and lower levels of resourcefulness were associated with worse self-rated health, while controlling for age, employment status, and weekly caregiving hours. Resourcefulness mediated the relationship between caregiving stress and self-rated health. Our findings highlight the importance of assessing the psychological impact of the pandemic on family caregivers' outcomes. Resourcefulness skills can be targeted to improve the health and well-being of family caregivers during and beyond the pandemic.Epstein-Barr virus (EBV) infection is prevalent and associated with distinct diseases including infectious mononucleosis (IM), chronic active EBV infection (CAEBV) and NK/T-cell lymphoma (NKTL). However, the specific roles of EBV in these diseases remain unclear. Here, the whole miRNA expression datasets derived from 7 IM, 6 CAEBV, and 3 NKTL biopsies were obtained. Homo sapiens microRNA-372-5p (Hsa-miR-372-5p) was upregulated in both CAEBV and NKTL patients. Overexpression of hsa-miR-372-5p altered the expression of over 100 proteins. Selleck Box5 In addition, hsa-miR-372-5p may target NIMA related kinase 7 to regulate NLRP3 inflammasome activation in host cell. Taken together, we reported different miRNA expression profiles in distinct EBV associated diseases, which provided novel insights to understand how host miRNAs contribute to the mechanism of EBV associated diseases. Hsa-miR-372-5p, as well as other differential expressed miRNA, might serve as potential targets in the therapy of various EBV associated diseases.The treatment landscape for patients with acute lymphoblastic leukemia (ALL) is changing. Continued investigation into the biology of ALL, and broader use and more precise methods of measuring residual disease allow for improved risk stratification of patients and identification of the subset of patients at greatest risk of disease relapse and who may benefit from hematopoietic cell transplantation (HCT) in first complete remission. Further, recent advances in HCT preparative regimens, donor selection, graft manipulation, and graft-versus-host disease prophylaxis and treatment have resulted in fewer transplant-related morbidities and mortality and better survival outcomes. Finally, the development of effective immunotherapeutic salvage agents, such as the chimeric antigen receptor T-cell therapy, tisagenlecleucel, have significantly changed the treatment landscape of this disease, allowing patients with advanced disease to be considered for HCT with curative intent. In this review, we will provide an update on the indications and outcome of pediatric and adult ALL.Homemade cloth masks and other improvised face coverings have become widespread during the COVID-19 pandemic driven by severe shortages of personal protective equipment. In this study, various alternative (mostly common household) materials, which have not traditionally been used in respiratory protective devices, were tested for particle filtration performance and breathability. Most of these materials were found of some-but rather limited-utility in facemasks. At a breathing flow rate of 30 L min-1, 17 out of 19 tested materials demonstrated collection efficiency below 50%; at 85 L min-1, only one material featured particle collection efficiency above 50%. Pressure drop values were mostly below 4 mm w.g. (observed in 89% of cases for the two flow rates), which provides comfortable breathing. Only for one fabric material (silk) tested at 85 L min-1 did the pressure drop reach 11 mm w.g. Based on these results, a three-layer facemask prototype was designed and fabricated comprised of the best performing materials. Additional tests were conducted to examine possible particle detachment/shedding from the materials used in the newly developed facemask, but no such phenomenon was observed. The prototype was evaluated on 10 human subjects using the standard OSHA-approved quantitative fit testing protocol. The mask protection level, determined as an adopted fit factor, was found to lie between that of the two commercial surgical/medical masks tested for comparison. A 10-cycle washing of the mask prototype lowered its collection efficiency across the particle size range; however, washing did not substantially affect mask breathability. The study revealed that although homemade masks offer a certain level of protection to a wearer, one should not expect them to provide the same respiratory protection as high-end commercial surgical/medical masks or-by any means-NIOSH-certified N95 filtering facepieces.
