Perforations, anastomotic leak, and subsequent intra-abdominal sepsis are among the most common feared complications of invasive interventions in colon remaining intestinal tract. During physiological healing, tissue protease activity is finely orchestrated to maintain strength integrity submucosa collagen layer wound. We (Shogan, BD et al. Sci Trans Med 7: 286ra68, 2015.) have previously demonstrated both mice humans that commensal microbe Enterococcus faecalis selectively colonizes wounded...

Osteoarthritis (OA) is a group of common, chronic, and painful inflammatory joint diseases. One important finding in OA patients remarkable decrease the molecular weight hyaluronic acid (HA) synovial fluid affected joints. Therapeutic HA available to most parts world as viscosupplementation product for treatment OA. Previous clinical reports show that high (HMWHA) more effectively relieves pain than low (LMWHA). However, mechanism behind this remains unclear. In study, we investigated...

Abstract – Habitat suitability criteria (HSC) for depth, mean velocity, nose substrate, embeddedness, and cover were developed brown trout ≥170 mm ( Salmo trutta Linnaeus) on the West Branch Farmington River, CT, USA. Microhabitat data was collected by underwater observation using an equal effort habitat sampling design; HSC constructed nonparametric tolerance limits. Transferability of previously published to River poor; only 1 13 tested considered transferable. The transferability East...

Objective: To investigate the role of bacterial- mediated plasminogen (PLG) activation in pathogenesis anastomotic leak (AL) and its mitigation by tranexamic acid (TXA). Background: AL is most feared complication colorectal resections. The pathobiology setting a technically optimal procedure involves excessive submucosal collagen degradation resident microbes. We hypothesized that host PLG system pathogens central targetable pathway AL. Methods: employed kinetic analysis binding human...

Background and Objectives:The advantages of laparoscopy over open surgery are well established. Laparoscopic resection for gastric cancer is safe results in equivalent oncologic outcomes when compared with resection. The purpose this study was to assess the use treat associated outcomes.Methods:The American College Surgeons National Surgical Quality Improvement Project (NSQIP) dataset queried patients (ICD-9 Code 151.0–151.9) from January 2005 through December 2012. Logistic regression used...

Although >10% of surgical patients receive alternative antibiotic prophylaxis for reported penicillin allergies, it is estimated that <20% such cases represent true allergies preclude standard prophylaxis. Each class has a distinct impact on the intestinal microbiota and postoperative metabolomics. The community structure function are linked to ability lose weight after bariatric surgery. This study demonstrates differential loss laparoscopic sleeve gastrectomy between who received...

We measured serum calcium concentrations in mature white suckers and bluegills collected from clear‐water Wisconsin lakes before spawning. The mean concentration female was greater a circumneutral lake than two naturally acidic lakes, whereas fish the did not differ. Serum four varied among but no relation apparent between level either pH or waterborne calcium. In contrast, strong negative correlation relative density of bluegill populations eight observed, suggesting that levels this...

Introduction The 2017 surgical infection society (SIS) guidelines recommend 4 days of antibiotic therapy after source control for complicated intra-abdominal infections (cIAIs). Inappropriate exposure to antibiotics has a negative impact on outcomes in individual patients and populations. goal this study was evaluate our institution’s practice patterns adherence current guidelines. Methods Medical records from 2010 2018 cIAIs were examined. Complicated appendicitis diverticulitis cases...
