Meta AnalysisThe impact of perioperative glutamine-supplemented parenteral nutrition on outcomes of patients undergoing abdominal surgery: a meta-analysis of randomized clinical trials.
The objective of this study was to evaluate the impact of perioperative glutamine-supplemented parenteral nutrition (GLN-PN) on clinical outcomes in patients undergoing abdominal surgery. MEDLINE, EMBASE, and the Cochrane Controlled Clinical Trials Register were searched to retrieve the eligible studies. Eligible studies were randomized controlled trials (RCTs) that compared the effect of GLN-PN and standard PN on clinical outcomes in patients undergoing abdominal surgery. ⋯ The overall effect indicated glutamine significantly reduced the length of hospital stay in the form of alanyl-glutamine (weighted mean difference [WMD], -3.17; 95% CI, -5.51 to -0.82; P = 0.008) and in the form of glycyl-glutamine (WMD, -3.40; 95% CI, -5.82 to -0.97; P = 0.006). A positive effect in improving postoperative cumulative nitrogen balance was observed between groups (WMD, 7.40; 95% CI, 3.16 to 11.63; P = 0.0006), but no mortality (RR, 1.52; 95% CI, 0.21 to 11.9; P = 0.68). Perioperative GLN-PN is effective and safe to shorten the length of hospital stay, reduce the morbidity of postoperative infectious complications, and improve nitrogen balance in patients undergoing abdominal surgery.

Comparative StudyWhat is the role of nodal ratio as a prognostic factor for gastric cancer nowadays? Comparison with new TNM staging system and analysis according to the number of resected nodes.
Nodal ratio (NR) has been demonstrated to be an important prognostic factor in patients with gastric cancer. The aim of this study is to evaluate the prognostic role of nodal ratio comparing it with the new TNM (2010) classification. One hundred forty-two patients were submitted to potentially curative gastrectomy for cancer. ⋯ Overall five-year survival was 81 per cent for N0 patients, 72 per cent for N1, and 26 and 23 per cent for N2 and N3, respectively. Patients with NR0 had 81 per cent five-year survival, whereas NR1 67 per cent, NR2 51 per cent, and NR3 22 per cent. NR seems to be a simple method to predict the prognosis of patients with gastric cancer; unlike N status, it is independent from the number of resected nodes, and therefore it is particularly useful in case of inadequate lymphadenectomy.

Comparative StudyCoronary stents and subsequent surgery: reported provider attitudes and practice patterns.
Management of antiplatelet therapy in patients with cardiac stents who need subsequent surgery is complex. Current guidelines recommend delaying elective surgery or, if surgery is emergent, proceeding without aspirin cessation. This study assessed provider knowledge, attitudes, and practices for patients with cardiac stents needing subsequent surgery. ⋯ In adjusted models for early surgeries, cardiologists and anesthesiologists were more likely to report continuation of dual therapy as compared with surgeons regardless of stent type (drug-eluting P = 0.03; bare metal P < 0.01). Despite successful guideline adoption, significant variations in practice patterns by provider type were found. Understanding reasons behind the variation and outcomes of various antiplatelet management strategies are important steps in optimizing care of patients with coronary stents undergoing noncardiac surgery.

Percutaneous cholecystostomy is a definitive treatment for acute cholecystitis in elderly high-risk patients.
Percutaneous cholecystostomy (PC) is an alternative treatment for acute cholecystitis (AC) in elderly patients with high surgical risk and has lower morbidity and mortality than emergency cholecystectomy. There is controversy about whether cholecystectomy should be performed after PC in elderly high-risk patients. Medical records of patients with AC admitted to the Department of Surgery, Jinling Hospital, Nanjing University School of Medicine, China, between January 2004 and July 2009 were reviewed retrospectively. ⋯ The one-year survival rate was 82.2 per cent, and the three-year survival rate was 39.7 per cent. No death was related to cholecystitis, but one patient died of septic shock on the second day after PC. Considering limited survival and a low recurrence rate of cholecystitis in elderly high-risk patients with AC, we propose that PC is a definitive treatment and cholecystectomy is not necessary after resolution of AC symptoms.
