Sarcopenia is a syndrome in which skeletal muscle reduction is the main manifestation of age-related and/or disease-related malnutrition associated with postoperative complications and mortality. ⋯ Sarcopenia is associated with the total length of hospital stay, postoperative hospital stay, and severe complications in GC patients undergoing gastrectomy. Moreover, SMI may be a more meaningful index than TPI in reducing the rate of misdiagnosis and in predicting adverse perioperative risk. In addition, sarcopenia may cause severe malnutrition and increases perioperative adverse risk. Thus, both sarcopenia and the NRS2002 nutritional score should be assessed during preoperative nutritional screening and evaluation for GC patients.

Acute kidney injury (AKI) is a common disorder with a high risk of mortality and development of chronic kidney disease. With the validation of the recent classification systems, RIFLE in 2004 and KDIGO, in use today, our understanding of AKI has evolved. We now know that community-acquired AKI is also associated with an increased risk of worse outcomes. ⋯ The second project of the 0 by 25 initiative, the Global AKI Snapshot (GSN) study, provided insights into the recognition, treatment, and outcomes of AKI worldwide [Mehta et al.: Lancet 2016;387:2017-25]. Following the GSN, a Pilot Project was designed to test whether education and a simple protocol-based approach can improve outcomes in patients at risk of community-acquired AKI in low-resource settings [Macedo: J Am Soc Nephrol 2017]. In this review, we will comment on the main findings and lessons learned from the 0 by 25 initiative.

Lactose intolerance primarily refers to a syndrome having different symptoms upon the consumption of foods containing lactose. It is one of the most common form of food intolerance and occurs when lactase activity is reduced in the brush border of the small bowel mucosa. ⋯ When lactose is not digested, it can be fermented by gut microbiota leading to symptoms of lactose intolerance that include abdominal pain, bloating, flatulence, and diarrhea with a considerable intraindividual and interindividual variability in the severity of clinical manifestations. These gastrointestinal symptoms could be similar to cow's milk allergy and could be wrongly labeled as symptoms of "milk allergy." There are important differences between lactose intolerance and cow's milk allergy; therefore, a better knowledge of these differences could limit misunderstandings in the diagnostic approach and in the management of these conditions.

Comparative Study
Increased Incretin But Not Insulin Response after Oral versus Intravenous Branched Chain Amino Acids.
Branched chain amino acids (BCAAs) are known to exert an insulinotropic effect. Whether this effect is mediated by incretins (glucagon like peptide 1 [GLP-1] or glucose-dependent insulinotropic peptide [GIP]) is not known. The aim of this study was to show whether an equivalent dose of BCAA elicits a greater insulin and incretin response when administered orally than intravenously (IV). ⋯ An equivalent dose of BCAA elicited a comparable insulin and greater incretin response when administered orally and not when administered through IV. We conclude that insulinotropic effects of BCAA are partially incretin dependent.
