Filter by:The purpose of this study is to determine if oral vancomycin used as primary Clostridium difficile prophylaxis can reduce the incidence of this infection in high-risk patients.
Implementation of perineural catheters may lead to infection by catheter colonization. Catheters may be colonized by the bacteria present on the skin. This is most often commensal organisms as Staphylococcus or gram negative bacilli. In a large study of 1416 peripheral nerve catheters, 28.7% of catheters were cultured positive. This colonization is most often silent because in the same study only 3% of patients had signs of local inflammation and one psoas abscess was observed (0.07%). The germs are most often coagulase negative staphylococci (61%) and gram negative bacillus (21.6%).
Microorganisms that colonize hospital environments play an important role in the transmission of hospital acquired infections (HAI) and multi-drug resistant organisms. Previous studies examining microorganisms in the hospital environment have been limited by reliance on targeted culture-based methods resulting in potentially missed or unrecognized organisms. Evidence now suggests that using microbiome analysis offers an innovative strategy that may improve our understanding of HAI and how best to prevent them. This pilot longitudinal observational study aims to characterize the taxonomic composition of microbial communities on environmental surfaces and people in these environments prior to and following the introduction of patients, caregiver, and hospital staff to newly constructed inpatient care areas at St. Jude Children's Research Hospital (SJCRH). This proposed study is uniquely characterized by evaluating the hospital environment of a pediatric immunocompromised oncology patient population that has not been studied in the past using advanced molecular techniques such as microbiome analysis. PRIMARY OBJECTIVE: - To describe the pattern of microbial communities of the hospital environment before, during and after patient occupancy of a newly constructed hospital space. SECONDARY OBJECTIVES: - To describe the similarity or difference of environment microbial communities to that of the humans occupying this environment in a newly occupied hospital space. - To describe the pattern in environment microbial communities after each step of disinfection (manual cleaning with chemical disinfectant and Ultraviolet light disinfection machine) after patient discharge from the inpatient hospital environment. - To evaluate the correlation between environmental Adenosine Triphosphate (ATP) measures and organism bioburden.
Most genital infections by human papillomaviruses (HPV) are asymptomatic or benign and clear within a few months or years. There infections are much less studies than chronic infections, even though they represent the main reservoir for the virus. The goal of this project is to decipher the kinetics of the virus and of the host immune response in acute HPV genital infections in your women. This will be performed by following women longitudinally and regularly in order to measure variations in virus load, immune cell count, cytokine concentration and antibody titers. The investigators will also investigate the interaction between these kinetics and host genetics and host vaginal microbiota
Both patient and staff safety are of major importance during the procedure of fibreoptic bronchoscopy. Patient safety depends partly on adequate disinfection of instruments and accessories used as well as careful monitoring during the procedure.
Unwarranted use of antibiotics for pediatric acute respiratory tract infections (ARTIs) and use of second-line, broad spectrum antibiotics for bacterial ARTIs has contributed to the rapid development of resistance in many strains of bacteria. Provider-parent communication during pediatric visits for ARTIs strongly influence antibiotic prescribing rates. The overall goal of this study is to develop and test a distance learning quality improvement (QI) program called Dialogue Around Respiratory Illness Treatment - DART. The DART program aims to improve provider communication practices and treatment decisions during pediatric ARTI visits, with the ultimate goal being to decrease rates of antibiotic prescribing for these illnesses in children.
ASPIRE-SSI is a prospective, observational, multicentre cohort study among adult surgical patients, which aims to determine the incidence of healthcare-associated S. aureus infections, particularly S. aureus surgical site infections (SSIs), across Europe and to assess the most important risk factors for this type of infection.
The purpose of the Prospective Clinical Evaluation of the FilmArray Lower Respiratory Tract Infection (LRTI) Panel BioFire Study #DX-SDY-024947 is to collect data in support of the proposal to the FDA to support the classification of the LRTI panel as an in vitro diagnostic device for the diagnosis of lower respiratory tract infections. The study will enroll up to 1500 specimens across at least 3 study sites of sputum and bronchoalveolar lavage (BAL) specimens that are left over as excess from routine clinical care. Additionally, the study will collect residual whole blood or blood fractionation to evaluate the utility of procalcitonin (PCT) as an additional test to diagnose lower respiratory infection when it is available. Enrolled sputum and BAL specimens will be run on the FilmArray LRTI panel. If residual whole blood or blood fractionation is available it will be sent to BioFire Diagnostics, LLC where they will perform PCT testing. All specimens will be excess from routine standard of care testing.
This is a multicenter prospective collection of leftover respiratory tract secretions, paired blood and NP swabs, and clinical circumstances from pediatric HCT patients, followed by next generation genomic sequencing, transcriptome analysis, protein biomarker measurement, and statistical modeling.
Rationale: Oral vaccination is known to induce a systemic immune response as well as an immune response in mucosal tissues, and can therefore serve as a model to study systemic and mucosal immunity. In this study, the oral cholera vaccine Dukoral® was chosen as model vaccine. The kinetics of the immune response and the interaction with a raw milk matrix have been evaluated in a previous, pilot study (NL49042.081.14). Based on the outcomes of this pilot, in this study oral cholera vaccination will be applied to study the support of immunity by raw milk, compared to heat-treated milk. The study design has been optimised based on previous results: study duration is extended and sample size is based on relevant change and known variation in the primary outcome parameters. Infections are an important worldwide cause of death, both in elderly and young children. Therefore, support of immunity could help to reduce the incidence of infections. To screen the potential of specific foods or food ingredients to support immunity, oral vaccination can serve as a model. In a previous study, this model was developed using oral cholera vaccination in human adult volunteers. In that study, raw milk was shown to support the immune response to vaccination. In this follow-up study, the effect of raw milk will be compared with pasteurized and ultra-heat treated (UHT) milk. Objective: To investigate whether pasteurized milk and/or UHT milk are able to enhance the immune response as induced by oral cholera vaccination, in comparison to raw milk and to regular vaccination. Study design: The study is designed as a single-blind randomized controlled trial of 6 weeks. Study population: Healthy subjects of 18-50 years of age. Interventions: 1) Raw milk, obtained from farms that comply to the high quality requirements for production of raw milk, and that has been screened according to the safety criteria for raw milk; 2) commercially available full-fat UHT milk; 3) commercially available full-fat pasteurized milk.
