Intestinal alkaline phosphatase (IAP) plays a pivotal role in maintaining gut health and well-being. Oral supplementation with IAP in mice improves gut barrier function and prevents luminal proinflammatory factors from gaining access to the circulation. In this study, we sought to explore the relationship between IAP and tight junction protein (TJP) expression and function. ⋯ Intestinal alkaline phosphatase is a major regulator of gut mucosal permeability and appears to work at least partly through improving TJP levels and localization. These data provide a strong foundation to develop IAP as a novel therapy to maintain gut barrier function.

Venous thromboembolism (VTE) can be a devastating postoperative complication, with about one-third of VTEs occurring post-discharge. We previously retrospectively evaluated the Caprini VTE risk assessment model (RAM) in postoperative lung and esophageal cancer patients, demonstrating that "high risk" patients were more likely to have a postoperative VTE. In this study, we sought to implement the RAM protocol in thoracic surgical patients to evaluate adherence, safety, and VTE outcomes. ⋯ Implementation of a VTE risk assessment protocol with extended course prophylaxis in high risk patients is safe and feasible for providers and thoracic surgical patients at a large safety net institution with a diverse patient population. Follow-up studies are needed to assess efficacy of the RAM in this surgical population.

Randomized Controlled Trial Comparative Study Pragmatic Clinical Trial
Program Director Perceptions of Surgical Resident Training and Patient Care under Flexible Duty Hour Requirements.
The Flexibility in Duty Hour Requirements for Surgical Trainees (FIRST) trial was a national, cluster-randomized, pragmatic, noninferiority trial of 117 general surgery programs, comparing standard ACGME resident duty hour requirements ("Standard Policy") to flexible, less-restrictive policies ("Flexible Policy"). Participating program directors (PDs) were surveyed to assess their perceptions of patient care, resident education, and resident well-being during the study period. ⋯ Program directors involved in the FIRST trial perceived improvements in patient safety, continuity of care, and multiple aspects of resident education and well-being with flexible duty hours.

Multicenter Study
Portal Vein Embolization Followed by Right-Side Hemihepatectomy for Hepatocellular Carcinoma Patients: A Japanese Multi-Institutional Study.
Portal vein embolization (PVE) is useful to expand the indications of major hepatectomy; however, its oncologic effects are not fully understood. This study aimed to confirm the efficacy of preoperative PVE for hepatocellular carcinoma patients. ⋯ Even though hepatocellular carcinoma patients who underwent preoperative PVE and right-side hemihepatectomy had a significantly larger resected liver volume on admission, they have a comparable long-term prognosis as patients with up front hepatectomy. In addition, PVE might decrease extrahepatic recurrences.
