Association Between Low Vitamin D Status and Colorectal Cancer
… Past studies have shown an association between vitamin D status and colorectal cancer rate. However, the researcher's objective is to use the cross sectional data collected in the NHANES III, which is a program of studies designed to assess the health and nutritional status of adults and …

Key Genotypes and the Response to Nutrient Supplementation in Crohn’s Disease
… at 26/10. Having gene variants associated with low levels of betacarotene, vitamin D and Omega-3 polyunsaturated fatty acids can impede the immune response. Not known is the prevalence of these variants in a New Zealand CD population. Methods Project One To identify in New Zealand adults with CD …

The Impact of Maternal Methyl-Donor Nutrient Supplementation on Vitamin D Status and Inflammation among Adult Offspring
… with higher risks of childhood obesity. Low vitamin D (VD) status is often observed among overweight and obese (OWO) individuals, enhancing their risk for the development of secondary complications, such as inflammatory bowel diseases, cardiovascular diseases, and cancers. In addition to …

Vitamin D status and longitudinal lung function decline in the Lung Health Study
Low vitamin D blood levels are postulated to be a risk factor for worse lung function, largely based on cross-sectional data. We sought to use longitudinal data to test the hypothesis that baseline plasma 25-hydroxyvitamin D [25(OH)D] is lower in subjects with more rapid lung function decline, …

Studies on the differentiation of inflammatory and regulatory T-cells
Low vitamin D is associated with an increased risk of autoimmune diseases, whose pathology might involve T\(_R\)\(_e\)\(_g\) and T\(_h\)17 dysregulation. Thus, understanding how vitamin D modifies CD4\(^+\) T-cell responses holds therapeutic potential. I therefore investigated the effect of …

Risk for Preeclampsia Associated with Nutritional Deficiencies and Modified by APOL1 Genotype
… in placental health and maintenance, such as vitamin D and folate, are important nutrients to assess in the risk of PE. As gestational age increases, the levels of vitamin D and folate potentially have incrementally increasing concentrations associated with PE. In addition to micronutrient …

Effects of vitamin D on pro-inflammatory cytokines associated with Non-alcoholic fatty liver disease
… shown a negative association between NAFLD and vitamin D levels. In fact, low vitamin D levels were correlated to histological severity, necro-inflammation and fibrosis in NAFLD. Vitamin D is recognized for its anti-inflammatory and anti-proliferative properties and mediates these functions …

The Role of Vitamin D in Skeletal Muscle Function and Regeneration
… the group of seco-steroids collectively termed Vitamin D. Skeletal muscle expresses both CYP27A1 and CYP27B1 encoding for the hydroxylases required to convert Vitamin D to 25[OH]D and subsequently the bioactive 1α-25-dihydroxyvitamin D3 (1α-25[OH]2D3) (Girgis et al., 2014b). Crucially, the …

Exploration of diet quality and physical activity level among British Bangladeshi population living in the United Kingdom.
… cut-offs (Choo, 2002; (Shaikh et al,. 2019). A low diet quality score was observed among both gender with a HEI scores of 38.31 points (±8.34) and 37.57 points (±7.33) respectively. Low physical activity level (PAL) 1.32 (±0.21) and 1.24 (±0.11) was observed between male and females …

Vitamin D in Human Health and Performance: The Pursuit of Evidence-Based Practice in an Era of Scientific Uncertainty
Background: Calciferol (vitamin D) is an essential nutrient that can be synthesized in the skin upon exposure to ultraviolet-B (UVB) light, or obtained through dietary and supplement sources. Traditionally known for its role in bone metabolism, vitamin D is currently described as a pleiotropic …

Uraemic vascular damage and calcification in children with chronic kidney disease
… and high phosphate, in association with low vitamin D levels, is key to the pathophysiology of ectopic vascular and soft tissue calcification. In addition, a number of treatment- related factors can potentially lead to a high calcium load, contributing to an increased risk of …

Do Calcium and Vitamin D Levels in Blood Predict Clinical Features and/or Response to Treatment in People with Psoriasis?
… is of interest to establish whether calcium or vitamin D serum levels are linked with response to treatment in people with variable (moderate to severe) psoriasis in our population. Aims: This study aims to establish whether: 1. Clinical type or severity of psoriasis is correlated with serum …

The Impact of Vitamin D Status upon Markers of Athlete Health
Introduction At present there is a pandemic of low serum vitamin D (25[OH]D) concentration, partly due to a lack of sun exposure (the primary route for synthesis) and modern lifestyle choices. The bioactive form of vitamin D, 1,25-dihydroxyvitamin D (1,25[OH]2D3) exerts its biological activity by …
