Zonulin Biomarker for Diagnosis of Hip and Knee Infections

Surgical Site InfectionZonulin

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.

Oral Antibiotic Prophylaxis in Colorectal Surgery

Surgical Site InfectionAnastomotic Leak

The investigators perform a case-control study to compare preparation before elective colorectal surgery. The first group is a prospective patient - registry in all patients with mechanical bowel preparation (MBP) and oral antibiotic prophylaxis the day before colorectal surgery. The second group is a historic collective of patients with MBP only and colorectal surgery. The cases were matches in American Society of Anesthesiologists (ASA) physical status classification system, BMI, operative procedure and risk factors.

WHO Checklist- Based Infection Prevention Guidelines in Mulago Hospital

Surgical Site Infection

This prospective cohort study will assess all mothers undergoing elective and emergency caesarean delivery in the labour ward theatre at Mulago National Referral Hospital based temporarily at Kawempe Hospital. Mothers will be recruited into the study systematically over a period of 3 months and follow-up daily until discharge or 30 days .

Wound Contamination During Orthopaedic Surgery

Surgical Site InfectionHip Fractures2 more

In the present study we will compare bacteriological findings and the incidence of SSI in relation to laminar airflow (LAF) ventilated ORs, conventional (also called displacement or mixed) ventilated ORs and conventional ventilated ORs with the addition of tables equipped with units providing a local LAF over the surgical instruments. The hypothesis is that there exist a correlation between number and types of airborne bacteria and bacteria in the surgical wound and on surgical instruments at the time of wound closure.
