Clinical, research, and public health implications of poor measurement of Vitamin D status

New initiatives to develop a standard reference method and the assignment of "true" values to samples provide a solution to these problems.

Are low sun exposure and/or Vitamin D risk factors for type 1 diabetes

Evidence supports that higher sun exposure and/or vitamin D sufficiency in pregnancy, or supplementation in early life, decreases type 1 diabetes risk

Ultraviolet radiation, Vitamin D and the development of obesity, metabolic syndrome and type-2 diabetes

Emerging findings suggest a protective role for ultraviolet radiation (UVR) and sun exposure in reducing the development of obesity and cardiometabolic dysfunction, but more epidemiological and clinical research is required that focuses on measuring the direct associations and effects of exposure to UVR in humans.

Recent developments and emerging trends in dietary vitamin D sources and biological conversion

This review elaborates on biochemical characteristics, in vivo metabolism, biological conversion through UV irradiation, as well as dietary fortification of vitamin D. Recent innovations in vitamin D utilization, including nanoencapsulation, direct or indirect addition, emulsion, ultrasound, microwave processing, CRISPR-Cas9 genome editing, as well as UV photoconversion, were summarized.

New research links poor language to lack of Vitamin D in womb

New research has found that children of mums who had low levels of Vitamin D during pregnancy are twice as likely to have language difficulties.

Calcium and Vitamin D for obesity: review of randomized controlled trials

Obesity often coexists with low calcium intake and vitamin D insufficiency.

Vitamin D C3-epimer levels are proportionally higher with oral vitamin D supplementation compared to ultraviolet irradiation of skin in mice but not humans

The proportion of 25(OH)D3 that undergoes epimerization is greater with oral vitamin D3 supplementation than exposure to UVR in mice, but not in humans

Predictors of vitamin D-containing supplement use in the Australian population and associations between dose and serum 25-hydroxyvitamin D concentrations

The prevalence of vitamin D-containing supplement use was generally low in the Australian population, particularly for single vitamin D supplements

Novel drug targets for asthma and COPD: Lessons learned from in vitro and in vivo models

This paper is a review of potential novel therapeutic targets or tools for the treatment of asthma and COPD.

Immune mechanisms by which topically applied vitamin D acts as a therapeutic agent

Vitamin D, nutrition, diet, therapeutic agent
