Dance as an Intervention to Reduce Fall Risk in Older Adults: A Systematic Review With a Meta-Analysis.

The purpose of this study was to summarize the evidence from randomized clinical trials on the effects of dance on fall risk in older adults through a systematic review with meta-analysis. Fall risk was assessed through timed up and go, Berg Balance Scale, or one-leg stand tests. Data are presented as mean differences for timed up and go test and standardized mean differences for Berg Balance Scale and one-leg stand tests between treatments with 95% confidence intervals, and calculations were performed using random effects models. Significance was accepted when p < .05. A significant difference was found between dance interventions and the control groups in the general analysis of fall risk assessed by timed up and go (mean differences: -1.446 s; 95% confidence interval [-1.586, -1.306]; p < .001) and Berg Balance Scale and one-leg stand tests (standardized mean differences: 0.737; 95% confidence interval [0.508, 0.966]; p < .001) in favor of the intervention group. Different dance interventions decreased the fall risk in older practitioners.

Effects of fructose consumption on postprandial TAG: an update on systematic reviews with meta-analysis.

The aim of this study was to re-examine the chronic effect (>7 d) of fructose consumption on postprandial TAG, in adolescents and adults. The research was carried out in March 2017 and used different electronic databases, such as Medline ® (Pubmed®), Embase® and Cochrane. The review considered clinical trials (parallel or crossed) that evaluated the effect of fructose consumption for a period longer than 7 d, in humans. Two investigators independently performed data extraction. The outcome was the absolute delta of TAG concentration in a 4-h postprandial period. The results were presented with delta mean difference between treatments with 95 % CI. The calculations were made based on random-effect models. Statistical heterogeneity of treatment effects between studies was assessed by Cochrane's 'Q Test' and 'I 2' inconsistency test. The meta-analysis of the twelve selected interventions (n 318) showed that fructose generated larger variation (δ) of TAG concentrations during the postprandial period, compared with other carbohydrates (mean difference: 8·02 (95 % CI 0·46, 15·58) mg/dl (0·09 (95 % CI 0·01, 0·18) mmol/l); I 2: 74 %). High heterogeneity was generated almost exclusively by one study, and its withdrawal did not alter the result. We concluded that chronic consumption of fructose (>7 d) has a negative role on postprandial TAG in healthy adolescents and adults, as well as in overweight/obese individuals, but not in diabetics.
