Kampm doi:10.1016/j.jphotobiol.2010.04.003 Multiple sclerosis (MS) risk is determined by environmental influences acting on the individual genetic background. Recent epidemiologic and experimental evidence supports a role of low environmental supplies of vitamin D in mediating an increased susceptibility to MS. We review available evidence suggesting t...

Vitamin D is important for the development, growth, and mineralization of the skeletal in neonates and children. Vitamin D is essential for intestinal absorption of calcium. Vitamin D is metabolized to 25-hydroxyvitamin D and then to 1,25-dihydroxyvitamin D. Pregnant women in developed countries often have insufficient serum concentrations of 25-hydroxyvitamin D and a supplementation of vitamin...

OBJECTIVE The aim of this study was to analyze the correlation of serum 25-hydroxyvitamin D level with vascular calcification in patients treated with hemodialysis. METHODS As a cross-sectional study, 126 patients receiving maintenance hemodialysis (MHD) in our hospital were enrolled in this study. According to the serum 25-hydroxyvitamin D level, the patients were divided into 25-hydroxyvita...

Lower serum level of 25-hydroxyvitamin D is associated with several negative outcomes. However, previous studies have indicated that 25-hydroxyvitamin D is associated with lung cancer risk and survival, but presented controversial results.PubMed and Embase databases were searched update to August 2017 to identify and quantify the potential association between 25-hydroxyvitamin D and lung cancer...

The main aim of the study was to determine the influence of genetic factors on the serum 25-hydroxyvitamin D response to vitamin D supplementation. The main outcome measure was an increase in serum 25-hydroxyvitamin D after vitamin D supplementation. The patients are part of a randomized controlled trial in individuals with prediabetes assigned to 20 000 IU of vitamin D3 per week or placebo for...

BACKGROUND & AIMS To explore vitamin D status and its dynamic changes during pregnancy in women living in Northeast China. The association between 25-hydroxyvitamin D and serum calcium, phosphate and parathyroid hormone was studied. Because vitamin D deficiency or thyroid dysfunction/autoimmunity during pregnancy may lead to similar adverse events, the relationship between 25-hydroxyvitamin D a...
