The Possible Role of Vitamin #D in Suppressing Cytokine Storm and Associated Mortality in #COVID-19 Patients

Large-scale data show that the mortality of COVID-19 varies dramatically across populations, although the cause of these disparities is not well understood. In this study we investigated whether severe COVID-19 is linked to Vitamin D (Vit D) deficiency. Method Daily admission, recovery and deceased rate data for patients with COVID-19 from countries with a large number of confirmed patients (Germany, South Korea (S. Korea), China … Continue reading The Possible Role of Vitamin #D in Suppressing Cytokine Storm and Associated Mortality in #COVID-19 Patients

Association of #bisphosphonate therapy with incident lower extremity #fractures in persons with spinal cord injuries/disorders

To investigate the association between prescriptions for bisphosphonates, calcium/Vitamin D supplements, and receipt of DXA screening, and incident fracture risk in men and women with a spinal cord injury/disorder (SCI/D).. There was no significant association between prescriptions for bisphosphonates and incident lower extremity fractures in men (OR 1.04, 95% CI: 0.62-1.77) or women (OR 1.02, 95% CI 0.28-3.75). In men, similar null associations were seen … Continue reading Association of #bisphosphonate therapy with incident lower extremity #fractures in persons with spinal cord injuries/disorders

Early High-Dose Vitamin #D3 for Critically Ill, Vitamin D–Deficient Patients

Vitamin D deficiency is a common, potentially reversible contributor to morbidity and mortality among critically ill patients.. ..A total of 1360 patients were found to be vitamin D–deficient during point-of-care screening and underwent randomization. Of these patients, 1078 had baseline vitamin D deficiency (25-hydroxyvitamin D level, <20 ng per milliliter [50 nmol per liter]) confirmed by subsequent testing and were included in the primary analysis … Continue reading Early High-Dose Vitamin #D3 for Critically Ill, Vitamin D–Deficient Patients

Effects of One Year of Vitamin #D and Marine #Omega-3 Fatty Acid Supplementation on Biomarkers of Systemic Inflammation in Older US Adults

..(VITAL) tested vitamin D (2000 IU/day) and/or n-3 FA (1 g/day) supplementation in a 2 × 2 factorial design among women ≥55 and men ≥50 years of age. Baseline characteristics were well balanced. In the active arms, 25-OH vitamin D rose 39% and n-3 FA rose 55% vs minimal change in placebo arms. Neither supplement reduced biomarkers at 1 year. Vitamin D resulted in 8.2% … Continue reading Effects of One Year of Vitamin #D and Marine #Omega-3 Fatty Acid Supplementation on Biomarkers of Systemic Inflammation in Older US Adults

Vitamin #D-VDR signaling inhibits Wnt/beta-catenin-mediated #melanoma progression and promotes anti-tumor immunity

..1α,25-dihydroxyvitamin D3 signals via the Vitamin D Receptor (VDR). Higher serum vitamin D is associated with thinner primary melanoma and better outcome, although a causal mechanism has not been established. As melanoma patients commonly avoid sun exposure, and consequent vitamin D deficiency might worsen outcomes, we interrogated 703 primary melanoma transcriptomes to understand the role of vitamin D-VDR signalling and replicated the findings in TCGA … Continue reading Vitamin #D-VDR signaling inhibits Wnt/beta-catenin-mediated #melanoma progression and promotes anti-tumor immunity

Comparison of #fracture risk using different supplemental doses of #vitamin D, #calcium or their combination: a network meta-analysis of randomised controlled trials

Inconsistent findings in regard to association between different concentrations of vitamin D, calcium or their combination and the risk of fracture have been reported during the past decade in community-dwelling older people A total of 25 randomised controlled trials involving 43 510 participants fulfilled the inclusion criteria. There was no evidence that the risk of total fracture was reduced using different concentrations of vitamin D, … Continue reading Comparison of #fracture risk using different supplemental doses of #vitamin D, #calcium or their combination: a network meta-analysis of randomised controlled trials
