In response to the coronavirus disease 2019 (COVID-19) pandemic, 107 countries had implemented national school closures by March 18, 2020. It is unknown whether school measures are effective in coronavirus outbreaks (eg, due to severe acute respiratory syndrome [SARS], Middle East respiratory syndrome, or COVID-19). We undertook a systematic review by searching three electronic databases… Continue reading School closure and management practices during coronavirus outbreaks including COVID-19: a rapid systematic review
Inverse association between serum 25-hydroxyvitamin D and nonalcoholic fatty liver disease
AbstractBackground & AimsSerum 25-hydroxyvitamin D (S-25(OH)D) and nonalcoholic fatty liver disease (NAFLD) are correlated in many observational studies, whereas the causality of this association is uncertain, especially in European populations. We conducted a bidirectional Mendelian randomization study to determine the association between S-25(OH)D and NAFLD. MethodsSeven and six independent genetic variants associated with S-25(OH)D and… Continue reading Inverse association between serum 25-hydroxyvitamin D and nonalcoholic fatty liver disease

Prevalence and Durability of SARS-CoV-2 Antibodies Among Unvaccinated US Adults by History of COVID-19
As of December 28, 2021, approximately 27% of the US population was unvaccinated against SARS-CoV-2,1 yet the prevalence of natural immunity remains unknown. Blood donor studies may have selection bias and lack clinical information.2 Previous COVID-19 infection is a possible surrogate for natural immunity, but 1 study suggested that 36% of COVID-recovered individuals are serologic… Continue reading Prevalence and Durability of SARS-CoV-2 Antibodies Among Unvaccinated US Adults by History of COVID-19
Evaluation of Adiposity and Cognitive Function in Adults
Excess adipose tissue increases other cardiovascular risk factors, which may be associated with vascular brain injury and cognitive impairment. However, the extent to which the amount and distribution of adipose tissue may be associated with lower cognitive scores, independent of its association with cardiovascular risk factors, is not well characterized. Objective To investigate the association… Continue reading Evaluation of Adiposity and Cognitive Function in Adults
Pre-infection 25-hydroxyvitamin D3 levels and association with severity of COVID-19 illness
Studies have demonstrated a potential correlation between low vitamin D status and both an increased risk of infection with SARS-CoV-2 and poorer clinical outcomes. This retrospective study examines if, and to what degree, a relationship exists between pre-infection serum 25-hydroxyvitamin D (25(OH)D) level and disease severity and mortality due to SARS-CoV-2. ParticipantsThe records of individuals… Continue reading Pre-infection 25-hydroxyvitamin D3 levels and association with severity of COVID-19 illness
Ketoconazole 2% Cream Alters the Skin Fungal Microbiome in Seborrheic Dermatitis: a Cohort Study
Seborrheic dermatitis (SD) is a common chronic inflammatory dermatosis. Current theories highlight the role of microbes on the skin surface in the pathogenesis of SD. Ketoconazole is commonly used for the treatment of SD. However, there remains limited data focusing on the effects of ketoconazole on shaping the skin microbiome in patients with SD. ObjectiveIn… Continue reading Ketoconazole 2% Cream Alters the Skin Fungal Microbiome in Seborrheic Dermatitis: a Cohort Study
Air quality improvement and cognitive decline in community-dwelling older women in the United States: A longitudinal cohort study
Late-life exposure to ambient air pollution is a modifiable risk factor for dementia, but epidemiological studies have shown inconsistent evidence for cognitive decline. Air quality (AQ) improvement has been associated with improved cardiopulmonary health and decreased mortality, but to the best of our knowledge, no studies have examined the association with cognitive function. We examined… Continue reading Air quality improvement and cognitive decline in community-dwelling older women in the United States: A longitudinal cohort study
Adipogenic Activity of Chemicals Used in Plastic Consumer Products
Bisphenols and phthalates, chemicals frequently used in plastic products, promote obesity in cell and animal models. However, these well-known metabolism-disrupting chemicals (MDCs) represent only a minute fraction of all compounds found in plastics. To gain a comprehensive understanding of plastics as a source of exposure to MDCs, we characterized the chemicals present in 34 everyday… Continue reading Adipogenic Activity of Chemicals Used in Plastic Consumer Products
