Filter by:Investigators designed an open, two-arm study to compare oral vancomycin with a fecal microbiota transplant (FMT) from a fecal donor-unrelated donor mix (FURM) as treatments for the first Clostridium difficile infection (CDI) episode among hospitalized patients.
The investigators hypothesize that long-term fermented high-fibre rye intake may reduce the Helicobacter pylori infection through dampening inflammation and thereby leading to lower adherence of the bacteria to surfaces.The investigators further hypothesize that that inflammation could be a potential causal link between HP infection and insulin resistance, a risk factor for type 2 diabetes and cardiovascular disease.
Urinary Tract Infection (UTI) complications following catheter use in surgical patients remains high. Using an aseptic protocol has been shown to drastically reduce UTI incidence by 50%. Reducing UTIs will prevent extended hospital stays, readmission, and antibiotic use associated with this complication and improve cost-effectiveness of care. The investigators hypothesize that they can reduce the incidence of UTIs after catheter placement with the implementation of a Quality Improvement (QI) protocol to prevent excess exposure to the environment exposure of the catheter before, during and after insertion.
Postoperative urinary tract infections (UTIs) affect 20-30% of patients undergoing elective gynecologic surgery and have a significant socioeconomic impact and cost. Preoperative antibiotics, sterile operating techniques, postoperative antibiotic and non-antibiotic medical therapies have been utilized to attempt to decrease this rate with little improvement. Utilization of an intraoperative antibiotic cystoscopic irrigant may decrease postoperative UTIs. The investigators have designed a prospective randomized controlled study to evaluate the effectiveness of an antibiotic cystoscopic fluid in preventing postoperative urinary tract infections in women undergoing elective pelvic floor surgery with cystoscopy.
The purpose of this study is to evaluate the effect of utilizing a rapid turnaround CT/NG test on treatment of female patients in the emergency department or urgent care setting with possible STIs.
Community-acquired pneumonia (CAP) is a heterogeneous disease causing great morbidity, mortality and health care burden globally. Typing methods for discriminating different clinical conditions of the same disease are essential to a better management of CAP. Traditional typing systems based separately on clinical manifestations (such as PSI and CURB-65), pathogens(bacterial types, virulence, drug resistance, etc) or host immune state (immunocompetent, immunocompromised or immunodeficiency). Thus, they are barely able to represent the real disease status nor to precisely predict the mortality. As the development of multi-omic technologies, the relatedness of different phenotypes at a molecular level have revolutionized our ability to differentiate among patients. Our study is aimed at establishing a novel molecular typing method of CAP. Multi-omic (including genomics, transcriptomes, and metabolisms) data obtained from enrolled CAP patients and isolated pathogens would be integrated analyzed and interpreted. Tthe investigators believe that an appropriate molecular typing method would lead to revolutionary changes in current arrangements of CAP.
Respiratory virus infections cause a majority of asthma exacerbations in the fall to spring months. Current diagnostic platforms for respiratory viruses have limitations including cost, availability, and invasiveness. The use of noninvasive breath collection to analyze breath metabolites may be used to differentiate virus-infected asthmatics from other causes of acute asthma exacerbations.
Cotrimoxazole preventive therapy (CPT) is recommended for prevention of morbidity and mortality due to Pneumocystis pneumonia and other infections in HIV positive patients with low immunity. Common clinical practice is to start CPT in any patient with CD4 counts below 200/µL, and, conversely, to stop CPT when immunity has been restored by antiretroviral treatment to CD4 counts above 200/µL or when viral suppression has been documented for 3 months. However, the latest WHO guidelines widely expands the indication for CPT by advocating for settings with high prevalence of malaria and bacterial infections, that all patients with HIV start CPT regardless of CD4 counts and clinical stage. Furthermore, WHO recommends these patients to continue CPT indefinitely regardless of evidence of immune restoration (The recommendation is for settings with high prevalence of malaria and bacterial infections, not for high-income countries). There is limited scientific evidence to recommend prolonged CPT, as studies have shown it is associated with modestly reduced morbidity due to pneumonia, meningitis and malaria, but no corresponding reduction in mortality. The impact of such a large increase in antibiotic use on the emergence of antimicrobial resistance has not been thoroughly considered. Our previous studies in Tanzania showed that multidrug-resistant bacteria frequently cause bloodstream infections with resultant very high case-fatality rates. As genes encoding for multiple antibiotic resistance traits are transferred by plasmids together with resistance towards cotrimoxazole, prolonged CPT will likely favor the selection of carriage of multidrug-resistant gut bacteria. The proposed randomized clinical trial is designed to assess whether prolonged CPT in HIV-positive patients results in increased fecal carriage of multi-drug resistant gut microbes or increased nasal carriage of methicillin-resistant Staphylococcus aureus (MRSA). Secondary endpoints are morbidity (clinical events, hospitalizations) and mortality. Stool specimens, nasal swabs and clinical data will be collected from persons attending voluntary counseling and testing facilities and HIV-clinics in Dar es Salaam, Tanzania. The study results may have important impact on public health in terms of assisting development of rational recommendations for CPT use, and may help prevent emerging antibiotic resistance.
This study validate the usefulness of SIMPLICITY score to characterize the immune status of the kidney transplant receiver at two points along its course (the one and six months after transplantation), by determination in peripheral blood of various parameters related to cellular immunity (count subpopulations of CD3+ (cluster of differentiation 3), CD4+ (cluster of differentiation 4) and CD8+( cluster of differentiation 8)), humoral immunity (immunoglobulins count) and innate (complement).
The purpose of this study is to assessed the efficacy of a combined solution of ethanol (4%) and low molecular weight heparins LMWH in preventing tunnelled dialysis catheter infection in chronic hemodialysis patients
