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.

Review Meta Analysis
Omega-3 polyunsaturated fatty acids in cardiac surgery patients: An updated systematic review and meta-analysis.
Omega-3 polyunsaturated fatty acids (ω-3 PUFA) supplementation is an attractive therapeutic option for patients undergoing open-heart surgery due to their anti-inflammatory and anti-arrhythmic properties. Several randomized controlled trials (RCT) have found contradictory results for perioperative ω-3 PUFA administration. Therefore, we conducted an updated systematic review and meta-analysis evaluating the effects of perioperative ω-3 PUFA on some clinically important outcomes for cardiac surgery. ⋯ In patients undergoing cardiac surgery, ω-3 PUFA supplementation by oral/enteral and parenteral route reduces hospital LOS and POAF. Nonetheless considerable clinical and statistical heterogeneity weaken our findings.

Review Meta Analysis
Optimal postoperative nutrition support for patients with gastrointestinal malignancy: A systematic review and meta-analysis.
To improve clinical outcomes, parenteral nutrition, standard enteral nutrition and immuno-enhanced nutrition are widely used in the gastrointestinal tumor patients undergoing surgery, but the optimal management of postoperative nutrition support remains uncertain. ⋯ Early use of Enteral nutrition in digestive tumor patients after surgery could significantly reduce the postoperative complications and shorten the length of hospital stay, IEN should be the optimal management, while the use of parenteral nutrition should be restrict to few patients with severe intolerance to enteral nutrition.

Review Meta Analysis
Coffee intake and the incident risk of cognitive disorders: A dose-response meta-analysis of nine prospective cohort studies.
Previous epidemiological studies have provided inconsistent conclusions on the impact of coffee consumption in the developing of cognitive disorders. However, no previous meta-analysis has pooled the evidence from the prospective cohort studies to assess the influence of coffee drinking and its potential dose-response patterns on the risk of developing cognitive disorders specifically. ⋯ A "J-shaped" association was presented between coffee intake and incident cognitive disorders, with the lowest risk of incident cognitive disorders at a daily consumption level of 1-2 cups of coffee.
