Active clinical trials for "Staphylococcal Infections"

This is a retrospective multinational, multicenter cohort study with a nested case-control. The study includes all surgical procedures performed at a participating site to prevent bias. Data will be assessed in two populations. Cohort population: Export of electronic file data on demographics, surgical procedure ICPM code, duration of procedure, American Society of Anesthesiologists (ASA) score, body mass index, comorbidity ICD codes, and wound class of all patients undergoing surgery. Nested case-control population: For patients establishing S. aureus SSI and 1:1 matched controls from the same center further data will be captured: Length of hospitalization, length of ICU stay and reason as well as attribution to SSI, survival at 30 and at 90 days, antibiotic treatments including duration, functional status at admission and at final discharge; necessity for surgical revision, and death attributed to SSI. If readmission is necessary, reason and attribution to SSI, length of hospitalization and length of ICU stay as well as all antibiotic treatments and their duration will be recorded. The cases causative pathogens including resistance patterns and type of SSI according to CDC criteria will be captured. Matching criteria comprise the following: Type of procedure Age ASA score BMI Duration of procedure (as percentile for this procedure) Diabetes Sex

The purpose of this investigation is to study the relationships between antimicrobial stewardship program efforts, antimicrobial drug use, and infection control efforts to the incidence rates of hospital acquired infections with Staphylococcus aureus in a sample of US academic medical center hospitals.

The intent of this study is to: Define the prevalence of MRSA carriage in the pediatric population in Kansas City. Systematically define patient risk factors for MRSA carriage and infection. Characterize the unique genetic characteristics of MRSA strains, both community acquired (CA) and healthcare associated (HCA) that are present in the different pediatric populations.

Staphylococcus lugdunensis is a coagulase-negative staphylococcus belonging to the human commensal cutaneous flora, and has been little studied in the field of prosthetic joint infections. However, it shares many virulence traits with Staphylococcus aureus, including many adhesins and its ability to form biofilm, and the few series of cases reports a significant failure rate.

This was a prospective study performed between November 2011 and September 2013. Patients with a confirmed S. epidermidis infection after fracture fixation or prosthetic joint infection were included. Exclusion criteria included infections involving external fixation pins, infections without any implanted hardware and culture positive patients not displaying any clinical sign of infection. The following surgical parameters were documented: affected bone or joint; type of implant; time between implantation of the device and onset of symptoms. Personal characteristics and patients'health status were also documented. Any revision surgeries involving the site of interest and all isolated pathogens were recorded throughout the course of treatment and follow-up. A follow up examination was performed an average of 26 months after discharge. Primary outcome at follow up was cure. Cure was define by the authors as: missing local (at site of interest) or systemic signs of infection, terminated surgical and systemic therapy and restoration of joint or limb function. At the first surgical procedure after enrolment, at least four deep bone biopsies were taken from the interface between implant and affected bone. Identification and antibiotic susceptibility testing of all growth was performed. Multi-drug-resistance (MDR) was defined according to the definitions of the European Committee of Antimicrobial Susceptibility Testing (EUCAST). Biofilm formation was analysed and quantified in microtitre plate assays according to protocol of Stepanovic et al.(see references).

The purpose of this study is to identify bacterial and/or clinical features involved in the pathogenesis of Staphylococcus aureus implant-associated infections (IAI). Materials & methods: In total, 57 IAI S. aureus and 31 nasal carriage (NC) S. aureus isolates were studied. Staphylococcus aureus genetic background was obtained by microarray analysis. Multilocus sequence typing was performed to determine clonal complexes (CC). Biofilm production was investigated by resazurin and crystal violet methods

1.To assess whether the Elution swab (ESwab) is superior to Amies transport swabs for the detection of Methicillin Resistant Staphylococcus aureus (MRSA) and Vancomycin Resistant Enterococci (VRE) in colonized patients and to determine whether nasal cultures alone is sufficient for detection of MRSA isolates in hospitalized patients. 2.To assess patient comfort in the use of the ESwab vs. Amies Transport swab for screening patients for methicillin resistant Staphylococcus aureus and vancomycin-resistant Enterococcus.

To study whether fluoroquinolone (trovafloxacin or levofloxacin), added to standard treatment, could reduce the high mortality and complication rates in Staphylococcus aureus bacteremia.

The purpose of this study is to investigate the role of T helper 17 cells (Th17) in the pathogenesis of MRSA infections.

To establish the clinical test performance characteristics of sensitivity, specificity and predictive values for direct detection of nasal Staphylococcus aureus colonization against clinical microbiology laboratory culture methods.
