Filter by:Prior studies investigating the etiopathogenesis of surgical site infection (SSI) traditionally suggested three main ways for the infection to occur: local contamination occurring during the surgery, hematogenous translocation of bacteria during concomitant bacteraemia, and contamination from adjacent infected tissues by the progression of the infective process. While most of the research on SSI focused on minimizing any source of pathogens at the time of the surgery, emerging evidence shows how acute and chronic SSI can emerge more often from bacteraemia or other tissues in the body, such as the gastrointestinal system, especially when dysbiosis and high permeability are retrieved. Intercellular tight junctions (TJs) tightly regulate paracellular antigen trafficking. TJs are extremely dynamic structures that operate in several critical functions of the intestinal epithelium under both physiological and pathological circumstances. This paradigm was subverted in 1993 by the discovery of zonula occludens 1 (ZO-1) as the first component of the TJ complex 11 now being comprised of more than 150 proteins, including occludin, claudins, junctional adhesion molecules (JAMs), tricellulin , and angulins . However, despite major progress in our knowledge on the composition and function of the intercellular TJ, the mechanisms by which they are regulated are still incompletely understood. One of the breakthroughs in understanding the role of gut permeability in health and disease has been the discovery of zonulin, and the only physiologic intestinal permeability modulator described so far. Since then, zonulin has been used as a marker for increased intestinal permeability and associated with soluble CD14 (sCD14) and lipopolysaccharide (LPS), other common markers associated with surgical complication, inflammation, and bacterial translocations. As such, Zonulin could be a biomarker for mid- and long-term complications after total joint replacement such as infection, loosening, and mechanical complications associated with painful symptomatology.
Healthcare-associated infections (HAIs) occur frequently and are associated with patient harm. It is important that healthcare facilities take the necessary steps to prevent the spread of resistant bacteria. ESKAPE bacteria (Enterococcus, S. aureus, Klebsiella, Acinetobacter, Pseudomonas, and Enterobacter spp.) are particularly pathogenic. Isolation of these pathogens from intraoperative reservoirs has been associated with postoperative infection development (i.e. surgical site infections). This project involves implementation of a software platform and bacterial collection system (OR PathTrac) that leverages the epidemiology of intraoperative bacterial transmission to guide dynamic, prospective improvements in perioperative infection control measures. We will assess the effectiveness of OR PathTrac feedback in optimizing an evidence-based, multifaceted, perioperative infection control program.
This study is a prospective, multi-institutional, noninferiority, randomized control trial that will compare the efficacy of two antibiotic treatments in preventing SSI in patients receiving immediate breast reconstruction with tissue expanders (TE-BR). The patients will be randomly assigned to one of the two treatment groups. One group will receive a single dose of antibiotics just before surgery and if necessary, more doses during the surgery. The other group will receive the same treatment as the first group, along with an additional week of antibiotics after surgery. The study will assess the rates of SSI from the two groups. It will also assess the type, duration and method (oral vs. intravenous) of subsequent antibiotic use for patients who develop SSIs in each group.
The overarching aim of this research project is to prevent orthopedic implant-associated infections. This study aims to investigate if PDT has an effect on bacterial skin colonization in order to improve skin antisepsis strategies for the prevention of surgical site infections.
To study whether a device has a nudging effect on the time spend on surgical rub.
The overall objective is to compare the effect of Vancomycin and Tobramycin powder combined (treatment) to Vancomycin powder (control) in the reduction of post-fixation infections of tibial plateau and tibial pilon fractures at high risk of infection (collectively considered the "study injuries").
This is a prospective randomized study to evaluate the difference in the rate of surgical site infection between the patients who used Sodium Picosulfate solution(PicosolutionⓇ) and tablet Oral Sulphate Solution(ORA·FANGⓇ) for bowel preparation before colorectal cancer surgery .
The aim of this study is to systematically explore the perioperative presence of P acnes in all layers of sternal wound incision as well as contamination of graft material and prosthetic valves during primary operation. Secondly, to compare if different regimes of antibiotics affects the bacterial growth. Cultures will be taken from the skin, subcutaneous, and from the implanted valve prostheses with a rayon swab.Graft and Felt material will, after being pressed subcutaneous for 15 sec, placed into prepared sterile bottles containing broth for aerobe and anaerobe cultures. Surgical gloves will be cultured.
The purpose of the study is to assess the effectiveness of a single dose of preoperative antibiotic in reducing surgical site infections in certain dermatological procedures. Patients will undergo surgical excision or Mohs surgery as is clinically indicated and part of usual care. The study will be a double blinded, placebo-controlled clinical trial. Patients meeting inclusion criteria will be assigned to one of three participant categories: 1) patients undergoing repair with skin flap or graft on the nose, 2) patients undergoing repair with skin graft, flap, or wedge resection on the ear, or 3) patients undergoing Mohs surgery with closure or partial closure or surgical excision on the lower extremity below the knee. Within each category, participants will be randomized into one of two groups: group one will receive a preoperative placebo pill and group two will receive preoperative antibiotic prophylaxis (either a single dose of Cephalexin 2g PO or single dose of Clindamycin hydrochloride 600 mg PO if allergy to penicillin or cephalosporin). Patients will followed for 30 days +/- 7 after surgery to evaluate for any surgical site infection.
Surgical hand scrubbing is the removal of transient flora and reduction of permanent flora as much as possible before any sterile gloves are worn before any surgical intervention. It is a cheap and easy method to prevent infections. Effective use of surgical hand scrubbing has an important role in preventing and reducing the transfer of health-related infections. Although many studies have been performed on surgical hand scrubbing, no standard practice has been found in the method of scrubbing and optimal duration of scrubbing time. The aim of this study is to compare evidence-based surgical hand scrubbing methods in order to prevent surgical site infections. Methods H0: There is no difference between the effectiveness of different surgical hand scrubbing methods on the bacterial flora in the hand H1: There is a difference between the effectiveness of different surgical hand scrubbing methods on the bacterial flora in the hand. Time H0: There is no difference between the effectiveness of different the duration of scrubbing time on the bacterial flora in the hand. H1: There is a difference between the effectiveness of different the duration of scrubbing time on the bacterial flora in the hand.
