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 associated with an increased risk of COVID-19 (OR = 1.43, 95% CI … 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 gene sequencing data. Faith’s Phylogenetic Diversity and non-redundant covariate analyses … 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 frailty progression in old-aged (24 to 28 months of age) … 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, 50.6% were women, 71.3% were self-declared non-Hispanic White participants, and … 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 patients older than 40 years who were vitamin D sufficient … 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 receptor is overexpressed in the duodenum of patients with #irritable bowel syndrome

Irritable bowel syndrome (IBS) is one of the most common functional gastrointestinal disorders and bile acids are thought to be associated with the pathogenesis of IBS. Bile acid receptors are expressed on intestinal epithelial cells. However, no study has assessed bile acid receptor proteins in IBS. Therefore, we examined the intestinal mucosal expression of bile acid receptors in patients with IBS.. Intestinal biopsies were performed … Continue reading Vitamin #D receptor is overexpressed in the duodenum of patients with #irritable bowel syndrome

Vitamin #D for treatment of non‐alcoholic #fatty liver disease detected by transient elastography: A randomized, double‐blind, placebo‐controlled trial

To evaluate the effects of vitamin D on transient elastography (TE, FibroScan) indices of liver steatosis (controlled attenuation parameter [CAP]) and fibrosis (liver stiffness measurement [LSM]) in adults with non‐alcoholic fatty liver disease (NAFLD).. ..Both CAP and LSM gradually decreased in vitamin D‐treated patients and slightly increased in the placebo arm. Vitamin D was superior to placebo for both primary outcomes (mean differences in CAP … Continue reading Vitamin #D for treatment of non‐alcoholic #fatty liver disease detected by transient elastography: A randomized, double‐blind, placebo‐controlled trial

Effect of Vitamin #D Supplementation on the Incidence of #Diabetes Mellitus

The effect of vitamin D supplementation on the risk of type 2 diabetes mellitus (T2DM) remains controversial because most randomized controlled trials (RCTs) have been small or have reported low doses of vitamin D.. ..Nine RCTs were included (43 559 participants). The mean age (standard deviation) was 63.5 (6.7) years. The RR for vitamin D compared with placebo was 0.96 (95% CI, 0.90-1.03); P = … Continue reading Effect of Vitamin #D Supplementation on the Incidence of #Diabetes Mellitus
