Meta AnalysisThe effects of hesperidin supplementation or orange juice consumption on anthropometric measures in adults: A meta-analysis of randomized controlled clinical trials.
The current evidence-base regarding the effect of hesperidin (a flavanone found in citrus fruits) on body composition is equivocal. ⋯ The present study revealed that there is no significant beneficial effect of orange juice and/or hesperidin supplementation on anthropometric measures. The authors advocate that more high-quality clinical trials are needed to better discern the potential efficacy of orange juice and/or hesperidin.

Review Meta AnalysisGlutamine dipeptide-supplemented parenteral nutrition improves the clinical outcomes of critically ill patients: A systematic evaluation of randomised controlled trials.
Early randomised controlled trials (RCTs) testing whether parenteral nutrition regimens that include glutamine dipeptides improves the outcomes of critically ill patients demonstrated convincingly that this regimen associates with reduced mortality, infections, and hospital stays. However, several new RCTs on the same question challenged this. To resolve this controversy, the present meta-analysis was performed. Stringent eligibility criteria were used to select only those RCTs that tested the outcomes of critically ill adult patients without hepatic and/or renal failure who were haemodynamically and metabolically stabilised and who were administered glutamine dipeptide strictly according to current clinical guidelines (via the parenteral route at 0.3-0.5 g/kg/day; max. 30% of the prescribed nitrogen supply) in combination with adequate nutrition. ⋯ This meta-analysis clearly confirms that when critically ill patients are supplemented with parenteral glutamine dipeptide according to clinical guidelines as part of a balanced nutrition regimen, it significantly reduces hospital mortality, infectious complication rates, and hospital LOS. The latter two effects indicate that glutamine dipeptide supplementation also confers economic benefits in this setting. The present analysis indicates the importance of delivering glutamine dipeptides together with adequate parenteral energy and nitrogen so that the administered glutamine serves as precursor in various biosynthetic pathways rather than simply as a fuel.
