Opioids are routinely used analgesics in patients with chronic wounds; however the impact of opioid exposure on wound healing is poorly understood. The purpose of this study was to investigate the association between opioid exposure and wound outcome in the WE-HEAL study. This longitudinal observational study was conducted on 450 subjects enrolled in the WE-HEAL biorepository. Data were collected prospectively including baseline characteristics, pain score, longitudinal opioid exposure, and total wound surface area (tWSA)...

BACKGROUND: Gastric cancer (GC) is characterized by the excessive deposition of extracellular matrix, which is thought to contribute to this tumor's malignant behavior. Epithelial-mesenchymal transition (EMT) is regarded as a crucial contributing factor to cancer progression. Galectin-1 (Gal-1), a β-galactoside-binding protein abundantly expressed in activated cancer-associated fibroblasts (CAFs), has been reported to be involved in GC progression and metastasis by binding to β1 integrin, which, in turn, can bind to matrix proteins and activate intracellular cascades that mediate EMT...

OBJECTIVES: Patients with diabetes mellitus often have more complicated postoperative courses and worse outcomes after coronary artery bypass grafting than those without this condition. Dipeptidyl-peptidase-4 inhibitors are a new class of oral medication for treating type 2 diabetes mellitus. We investigated how these drugs influence the postoperative course after coronary artery bypass in patients with type 2 diabetes mellitus. METHODS: We retrospectively reviewed the clinical records of 177 patients with type 2 diabetes who has undergone coronary artery bypass surgery between 2009 and 2013; 107 were treated with dipeptidyl-peptidase-4 inhibitors postoperatively, and 70 who did not receive dipeptidyl-peptidase-4 inhibitors served as a control group...

We assessed wound healing in patients on hemodialysis (HD) with critical limb ischemia (CLI). This study enrolled 267 patients (including 120 patients on HD and 147 patients not on HD) who underwent endovascular therapy (EVT) for CLI. The primary endpoint was wound-healing rate at two years. Secondary endpoints were time to wound healing, wound recurrence rate, and limb salvage at two years. The percentage of male and young patients was higher in the HD patients (p < 0.01). A lower patency of the pedal arch after EVT was observed frequently in HD patients (p < 0...

BACKGROUND: The definition of angiosome-targeted revascularization is confusing, especially when a tissue lesion affects several angiosomes. Two different definitions of direct revascularization exist in the literature. The study aim was (1) to compare the 2 definitions of direct revascularization in patients with foot lesions involving more than one angiosome and (2) to evaluate which definition better predicts clinical outcome. METHODS: This study cohort comprises 658 patients with Rutherford 5-6 foot lesions who underwent infrapopliteal endovascular or surgical revascularization between January 2010 and July 2013...

OBJECTIVE: Elevated serum phosphate levels have been associated with increased risks of cardiovascular events and death in several patient populations. The effects of serum phosphate on outcomes in patients with critical limb ischemia (CLI) have not been evaluated. In this study, we assessed the effect of abnormal phosphate levels on mortality and major limb events after surgical intervention for CLI. METHODS: A retrospective review was undertaken to identify all patients at a single institution who underwent a first-time open or endovascular intervention for CLI between 2005 and 2014...

BACKGROUND AND OBJECTIVE: The systemic responses triggered by burns and resuscitative measures may cause pulmonary damage and edema in the acute phase. These effects may occur in the absence of inhalation injury. Currently, there is a paucity of data on the recovery of the respiratory system postburn. This study aimed to examine 10-year hospital service use for respiratory morbidity in children with cutaneous burns and no smoke inhalation injury. METHODS: A population-based longitudinal study with 10-year follow-up using linked hospital and death from Western Australia for children <5 years when hospitalized for a first burn injury (n = 5290) between 1980 and 2012 and a frequency matched noninjury comparison cohort, randomly selected from Western Australia's birth registrations (n = 27 061)...

BACKGROUND: The individual and societal burden of Alzheimer's disease (AD) is substantial. Identifying relevant factors deteriorating AD and inducing need for nursing care would be of high relevance for healthcare planning. OBJECTIVE: The main objective of this study was the identification of predictors of first assignment of a level of long-term care in AD, used as an approximation for disease progression. METHODS: In a retrospective cohort study using data from a large German statutory health and long-term care insurance (SHI) company, co-morbidities and drug exposure were evaluated with respect to their predictive value for disease progression (first day the amount of daily nursing care exceeded 1...

Importance: Epidural analgesia (EA) is used as an adjunct procedure for postoperative pain control during elective abdominal aortic aneurysm (AAA) surgery. In addition to analgesia, modulatory effects of EA on spinal sympathetic outflow result in improved organ perfusion with reduced complications. Reductions in postoperative complications lead to shorter convalescence and possibly improved 30-day survival. However, the effect of EA on long-term survival when used as an adjunct to general anesthesia (GA) during elective AAA surgery is unknown...

BACKGROUND: Patients with morbid obesity, defined as a BMI greater than 40 kg/m(2), and super obesity, defined as a BMI greater than 50 kg/m(2), increasingly present for total hip replacement. There is disagreement in the literature whether these individuals have greater surgical risks and costs for the episode of care, and the magnitude of those risks and costs. There also is no established threshold for obesity as defined by BMI in identifying increased complications, risks, and costs of care...

INTRODUCTION: Timely hemorrhage control is paramount in trauma; however, a critical time interval from emergency department arrival to operation for hypotensive gunshot wound (GSW) victims is not established. We hypothesize that delaying surgery for more than 10 minutes from arrival increases all-cause mortality in hypotensive patients with GSW. METHODS: Data of adults (n = 309) with hypotension and GSW to the torso requiring immediate operation from January 2004 to September 2013 were retrospectively reviewed...

BACKGROUND: The significance of hospital readmission after endovascular therapy for critical limb ischemia (CLI) is not well established. We sought to investigate the incidence, timing, and causes of readmissions after endovascular therapy for CLI and whether readmission is associated with major adverse limb events (MALE) or mortality. METHODS AND RESULTS: This was a retrospective study of 252 patients treated with endovascular therapy for CLI. During median follow-up of 381 days (interquartile range [IQR], 115-718), 140 (56%) were readmitted, with median time to readmission of 83 days (IQR, 33-190)...

BACKGROUND: A follow-up analysis from a large trial of oxygen and surgical-site infections reported increased long-term mortality among patients receiving supplemental oxygen, especially those having cancer surgery. Although concerning, there is no obvious mechanism linking oxygen to long-term mortality. We thus tested the hypothesis that supplemental oxygen does not increase long-term mortality in patients undergoing colorectal surgery. Secondarily, we evaluated whether the effect of supplemental oxygen on mortality depended on cancer status...

PURPOSE: Excessive ST3Gal-I levels predict a poor outcome for patients with several types of tumors. This study aims to investigate the role of ST3Gal-I in determining the invasive and metastatic potential of human hepatocellular carcinoma (HCC) and clinical prognosis for patients with HCC. METHODS: We compared the expression of ST3Gal-I in various HCC cell lines and in 20 pairs of tumor and peritumor tissue samples using Western blot analysis. Changes in the degree of invasiveness and migration were determined before and after small interfering RNA-induced knockdown of ST3Gal-I using a Transwell matrigel invasion assay and scratch wound assay...
