Review Meta Analysis
Effect of alpha-lipoic acid supplementation on lipid profile: A systematic review and meta-analysis of controlled clinical trials.
Several studies have shown the effect of alpha-lipoic acid (ALA) on lipid profile. However, findings remain controversial. This systematic review and meta-analysis was conducted to systematically summarize the available clinical trials that examined the effects ALA supplementation on the lipid profile of adults. ⋯ Significant changes were not observed in serum high-density lipoprotein (WMD, -0.092 mg/dL; 95% CI, -3.014 to 2.831; P = 0.025). Supplementation dosage and body mass index were potential sources of heterogeneity, in which those with body mass index >30 kg/m2 who received >600 mg/d ALA showed better improvements in lipid profile. Our findings showed that supplementation with ALA significantly decreased the serum concentrations of TG, total cholesterol, and low-density lipoprotein but did not affect serum levels of high-density lipoprotein in adults.

The aim of this review is to summarize recent developments on the mechanisms involved in stress hyperglycemia associated with critical illness. Different aspects of the consequences of stress hyperglycemia as well as the therapeutic approaches tested so far are discussed: the physiological regulations of blood glucose, the mechanisms underlying stress hyperglycemia, the clinical associations, and the results of the prospective trials and meta-analyses to be taken into consideration when interpreting the available data. Current recommendations, challenges, and technological hopes for the future are be discussed.

Randomized Controlled Trial
Effects of cholecalciferol supplementation on inflammatory markers and muscle damage indices of soccer players after a simulated soccer match.
Soccer-induced muscle damage and inflammation lead to a reduction in athletic performance. The aim of this study was to determine whether supplementation with cholecalciferol would reduce inflammation and muscle damage in soccer players after a simulated soccer match. ⋯ The study showed that 50 000 IU/wk of cholecalciferol supplementation for 8 wk increased the 25-hydroxyvitamin D levels, with no effect on muscle damage indices or CRP. However, The IL-6 concentration was generally higher in the intervention group.

Digestive health plays key role in our active daily life; but maintaining proper bowel movements, i.e., being free from constipation, diarrhea, irritable bowel syndrome, inflammatory bowel disease, flatulence, bloating, and abdominal pain, is complex. Dietary fibers often are recommended to maintain proper digestive health, but none seems to provide a single comprehensive solution for overall maintanance of proper digestive health. Guar fiber, however, has emerged as a credible candidate for just such a solution. ⋯ The studies suggest that a regular intake of 5 to 10 g/d guar fiber is effective to treat most of the morbidities associated with digestive health. Guar fiber is all natural. It may offer potential protection and promotion of digestive health both alone and when combined with probiotics as a synbiotic formula.

Observational Study
Diet quality of patients with acute coronary syndrome receiving public and private health care.
The aim of this study was to investigate the quality of the diets consumed by patients with acute coronary syndrome (ACS) who received public and private health care. ⋯ The overall post-ACS diet quality remained unsatisfactory, especially in terms of cardioprotective components and among patients receiving public health care. Sociodemographic factors and the assistance model/quality were determinants of the observed differences in dietary quality.
