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
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
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.

Early oral feeding is the preferred mode of nutrition for surgical patients. Avoidance of any nutritional therapy bears the risk of underfeeding during the postoperative course after major surgery. ⋯ The focus of this guideline is to cover nutritional aspects of the Enhanced Recovery After Surgery (ERAS) concept and the special nutritional needs of patients undergoing major surgery, e.g. for cancer, and of those developing severe complications despite best perioperative care. From a metabolic and nutritional point of view, the key aspects of perioperative care include: • integration of nutrition into the overall management of the patient • avoidance of long periods of preoperative fasting • re-establishment of oral feeding as early as possible after surgery • start of nutritional therapy early, as soon as a nutritional risk becomes apparent • metabolic control e.g. of blood glucose • reduction of factors which exacerbate stress-related catabolism or impair gastrointestinal function • minimized time on paralytic agents for ventilator management in the postoperative period • early mobilisation to facilitate protein synthesis and muscle function The guideline presents 37 recommendations for clinical practice.
