Deficient (ie, <20 ng/mL) or insufficient (ie, 20 to <30 ng/mL) 25-hydroxyvitamin D (also known as calcifediol) levels are more common in Black individuals than White individuals and are associated with increased coronavirus disease 2019 (COVID-19) risk. Whether COVID-19 risk is associated with differences in vitamin D levels of 30 ng/mL or greater is not… Continue reading Association of Vitamin #D Levels, Race/Ethnicity, and Clinical Characteristics With #COVID-19 Test Results

Effect of Marine #Omega-3 Fatty Acid and Vitamin #D Supplementation on Incident Atrial #Fibrillation
Atrial fibrillation (AF) is the most common heart rhythm disturbance, continues to increase in incidence, and results in significant morbidity and mortality. The marine omega-3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), and vitamin D have been reported to have both benefits and risks with respect to incident AF, but large-scale, long-term randomized… Continue reading Effect of Marine #Omega-3 Fatty Acid and Vitamin #D Supplementation on Incident Atrial #Fibrillation
Circulating Vitamin #D levels status and clinical prognostic indices in #COVID-19 patients
Several immune mechanisms activate in COVID-19 pathogenesis. Usually, coronavirus infection is characterized by dysregulated host immune responses, interleukine-6 increase, hyper-activation of cytotoxic CD8 T lymphocytes. Interestingly, Vitamin D deficiency has been often associated with altered immune responses and infections. In the present study, we evaluated Vitamin D plasma levels in patients affected with different lung… Continue reading Circulating Vitamin #D levels status and clinical prognostic indices in #COVID-19 patients
Low vitamin #D status is associated with #coronavirus disease 2019 outcomes: A systematic review and meta-analysis
Observational studies suggest that the risk and clinical prognosis of coronavirus disease 2019 (COVID-19) are related to low vitamin D status; however, the data are inconsistent.. ..A total of 10 articles with 361, 934 participants were selected for meta-analysis. Overall, the pooled OR in the fixed-effect model showed that vitamin D deficiency or insufficiency was… Continue reading Low vitamin #D status is associated with #coronavirus disease 2019 outcomes: A systematic review and meta-analysis
Vitamin #D metabolites and the gut #microbiome in older men
The vitamin D receptor is highly expressed in the gastrointestinal tract where it transacts gene expression. With current limited understanding of the interactions between the gut microbiome and vitamin D, we conduct a cross-sectional analysis of 567 older men quantifying serum vitamin D metabolites using LC-MSMS and defining stool sub-Operational Taxonomic Units from16S ribosomal RNA… Continue reading Vitamin #D metabolites and the gut #microbiome in older men
Vitamin #D Insufficiency Reduces Grip Strength, Grip Endurance and Increases Frailty in Aged C57Bl/6J Mice
Low 25-OH serum vitamin D (VitD) is pervasive in older adults and linked to functional decline and progression of frailty. We have previously shown that chronic VitD insufficiency in “middle-aged” mice results in impaired anaerobic exercise capacity, decreased lean mass, and increased adiposity. Here, we examine if VitD insufficiency results in similar deficits and greater… Continue reading Vitamin #D Insufficiency Reduces Grip Strength, Grip Endurance and Increases Frailty in Aged C57Bl/6J Mice
Effect of Vitamin #D and ω-3 #Fatty Acid Supplementation on Risk of Age-Related #Macular Degeneration An Ancillary Study of the VITAL Randomized Clinical Trial
Observational studies suggest that higher intake or blood levels of vitamin D and marine ω-3 fatty acids may be associated with lower risks of age-related macular degeneration (AMD). However, evidence from randomized trials is limited.. ..In total, 25 871 participants with a mean (SD) age of 67.1 (7.0) years were included in the trial. Of them,… Continue reading Effect of Vitamin #D and ω-3 #Fatty Acid Supplementation on Risk of Age-Related #Macular Degeneration An Ancillary Study of the VITAL Randomized Clinical Trial
Vitamin #D sufficiency, a serum 25-hydroxyvitamin D at least 30 ng/mL reduced risk for adverse clinical outcomes in patients with #COVID-19 infection
..Based on CDC criteria, among our study patients, 74% had severe COVID-19 infection and 32.8% were vitamin D sufficient. After adjusting for confounding factors, there was a significant association between vitamin D sufficiency and reduction in clinical severity, inpatient mortality serum levels of C-reactive protein (CRP) and an increase in lymphocyte percentage. Only 9.7% of… Continue reading Vitamin #D sufficiency, a serum 25-hydroxyvitamin D at least 30 ng/mL reduced risk for adverse clinical outcomes in patients with #COVID-19 infection
Vitamin #D sufficiency, a serum 25-hydroxyvitamin D at least 30 ng/mL reduced risk for adverse clinical outcomes in patients with #COVID-19 infection
To investigate the association between serum 25-hydroxyvitamin D levels and its effect on adverse clinical outcomes, and parameters of immune function and mortality due to a SARS-CoV-2 infection.. ..Based on CDC criteria, among our study patients, 74% had severe COVID-19 infection and 32.8% were vitamin D sufficient. After adjusting for confounding factors, there was a… Continue reading Vitamin #D sufficiency, a serum 25-hydroxyvitamin D at least 30 ng/mL reduced risk for adverse clinical outcomes in patients with #COVID-19 infection
