Review Meta Analysis
Serum selenium level and gestational diabetes mellitus: a systematic review and meta-analysis.
The association between serum selenium level and gestational diabetes mellitus (GDM) is controversial. The aim of our study was to systematically review available literature linking selenium to GDM for a comprehensive understanding of the relationship between serum selenium level and GDM in human. ⋯ The available evidences suggested that serum selenium level was lower in women with GDM than those with normal glucose tolerance, especially within the non-Caucasian population and in the third trimester. However, well-designed prospective studies are needed to understand dynamic associations between selenium status and GDM risk.

Meta Analysis
Vitamin D deficiency is associated with increased risk of Alzheimer's disease and dementia: evidence from meta-analysis.
In recent years, the associations between vitamin D status and Alzheimer's disease (AD) and dementia have gained increasing interests. The present meta-analysis was designed to estimate the association between vitamin D deficiency and risk of developing AD and dementia. ⋯ Available data indicates that lower vitamin D status may be associated with increased risk of developing AD and dementia. More studies are needed to further confirm the associations and to evaluate the beneficial effects of vitamin D supplementation in preventing AD and dementia.
