Association between physical activity measured by accelerometry and cognitive function in older adults: a systematic review.

Objective: To analyze studies that investigated the association between physical activity assessed by accelerometry and cognitive function in older people.

Methods: A systematic review was carried out in four electronic databases (PubMed, Web of Science, Scopus, and SportsDiscus).

Results: In total, 195 records were identified.

The effect of physical activity on total homocysteine concentrations and cardiovascular risk in older Brazilian adults with type 2 diabetes.

A low level of physical activity has a potential association with high levels of homocysteine, which implies an increased chance of older adults with type 2 diabetes mellitus developing cardiovascular disease (CVD). However, the effects of physical activity on homocysteine levels have been poorly explored in the literature. Therefore, this study compared homocysteine levels and cardiovascular risk among physically active and inactive older women with type 2 diabetes mellitus.

Effects of Creatine Supplementation on Renal Function: A Systematic Review and Meta-Analysis.

Creatine supplements are intended to improve performance, but there are indications that it can overwhelm liver and kidney functions, reduce the quality of life, and increase mortality. Therefore, this is the first systematic review and meta-analysis study that aimed to investigate creatine supplements and their possible renal function side effects. After evaluating 290 non-duplicated studies, 15 were included in the qualitative analysis and 6 in the quantitative analysis.
