Effect of vitamin D supplementation on non-skeletal disorders: a systematic review of meta-analyses and randomised trials.

Randomised trials reported up to Dec 31, 2012, did not confirm that vitamin D supplementation could protect from non-skeletal health conditions affecting adults, as was expected on the basis of data from observational studies. To examine whether the more recently published meta-analyses and trials would change past conclusions, we systematically reviewed meta-analyses of vitamin D supplementation and non-skeletal disorders published between Jan 1, 2013, and May 31, 2017, that included study participants of all ages, including pregnant women. We also searched for randomised trials not included in meta-analyses.

Physical activity and change in fasting glucose and HbA1c: a quantitative meta-analysis of randomized trials.

Aims: A systematic review was conducted of randomized trials which evaluated the impact of physical activity on the change in fasting glucose and HbA1c.

Methods: A literature search was conducted in PubMed until December 2015. Studies reporting glucose or HbA1c at baseline and at the end of study were included, and the change and its variance were estimated from studies with complete data.

Prognostic Value of 25-hydroxyvitamin D3 Levels at Diagnosis and During Follow-up in Melanoma Patients.

Background: A low 25-hydroxyvitamin D3 (25(OH)D3) serum concentration at melanoma diagnosis might be associated with worse survival. We prospectively studied the prognostic value of 25(OH)D3 at diagnosis and during follow-up.

Methods: MelanCohort is a cohort of invasive melanoma patients.
