The Potential benefits and possible risks of perioperative supplementation with probiotics/synbiotics in surgical patients are not fully understood. Recent evidence has rapidly evolved and conveys conflicting results. Thus, we undertook a meta-analysis of randomized controlled trials (RCTs) to valuate the effectiveness, safety, cost-effectiveness and quality of life of perioperative supplementation with pro-/synbiotics. ⋯ For surgical patients, perioperative supplementation with pro-/synbiotics is effective in preventing or controlling SSI and other infectious complications. Perioperative pro-/synbiotics might also be associated with fewer side effects, lower hospital cost and better quality of life. Current evidence indicated that perioperative synbiotics supplementation is preferred and recommended as an adjunct in surgical patients.

Meta Analysis
Alpha-lipoic acid supplement in obesity treatment: A systematic review and meta-analysis of clinical trials.
Previous studies have supported positive roles of antioxidant supplements on weight-loss. One antioxidant supplement is Alpha-lipoic acid. However, recommending ALA as an anti-obesity supplement remains controversial. Accordingly, the purpose of the present study was to perform a meta-analysis on the effects of ALA supplement on anthropometric indices among adult subjects. ⋯ The present study revealed that supplementation with ALA slightly but significantly decreased body weight and BMI. Safe dosage for ALA is up to 1200 mg/day. However, it seems that ALA cannot be cost-effective. Further studies are needed to clarify the effects of ALA on metabolic parameter in unhealthy obese individuals.
