Filter by:Approximately, 3% of males and 8% of females will develop a urinary tract infection (UTI) during childhood, and most of these will be effectively treated by short-term antibiotic therapy. A subset of these children (20-48%), will develop recurrent UTI (RUTI), which may have long-term effects in the form of hypertension or renal damage. In an effort to prevent RUTIs physicians prescribe sulfamethoxazole-trimethoprim (Septra) or nitrofurantoin as low dose antibiotic prophylaxis. However, recent evidence suggests that during prophylactic therapy the body is exposed to antibiotic levels capable of increasing antibiotic resistance and bacterial virulence. This has been shown to be true in the uropathogens E. coli and Staphylococcus saprophyticus, yet it is not known if Enterococcus sp. demonstrate similar mechanisms. Additionally, antibiotics have been shown to disrupt the natural balance of the human microbiome, potentially leading to major long term problems. As a uropathogen, enterococci consistently rank in the top 3 causes of RUTI, especially in children under 3 years of age. Additionally, Enterococcus is notorious for developing antibiotic resistance and studies have shown that children with enterococcal UTIs exhibit a higher rate of recurrence than those with non-enterococcal UTIs. The investigators hypothesize the current practice of antibiotic prophylaxis in children with RUTI is detrimental and can change the bacterial and sensitivity profiles of these patients.
In order to improve the investigators knowledge about uveitis and the underlying mechanism of disease, the investigators propose collecting blood from patients with uveitis, isolating DNA and sequencing the DNA to identify genetic mutations or associations in these patients.
The purpose of this study is to evaluate the safety and efficacy of ombitasvir/paritaprevir/ritonavir and dasabuvir with or without sofosbuvir (SOF) and ribavirin (RBV) in DAA treatment-experienced adults with Genotype 1 Chronic Hepatitis C Virus infection. This study will contain 2 parts. Part 1: Approximately 20 participants and at least 10 of the 20 participants previously treated with the combination of ombitasvir/paritaprevir/ritonavir and dasabuvir, with or without RBV, and experienced treatment failure. Part 2: Approximately 10 participants and all participants previously treated with SOF/ledipasvir and experienced treatment failure.
The study aims to address the following aims 1. To provide an overview of the epidemiology of the patients who are managed in the Singapore General Hospital for NTM infections. 2. To evaluate the medical care of patients in the institution with regards to the type of medical and/or surgical treatment received and specifically, the antibiotic regime and duration administered. 3. A longitudinal follow up which will allow an assessment of our care and patient outcome in this population cohort
GSK1265744 (744) is an integrase strand transfer inhibitor (INSTI) currently in development for both the treatment and prevention of human immunodeficiency virus (HIV) infection. Renal elimination of unchanged 744 is extremely low, with no parent 744 detected in the urine after a single 30 mg radiolabeled dose. Despite the minimal contribution of renal clearance on overall 744 elimination, renal impairment may potentially inhibit some pathways of hepatic and gut drug metabolism and transport, and as a result may impact 744 pharmacokinetics. The current Food and Drug Administration (FDA) draft guidance for renal impairment studies suggests that a pharmacokinetic (PK) study in patients with renal impairment be conducted even for those drugs primarily metabolized or secreted in bile. The study will be comprised of two cohorts (severe renal impairment and normal renal function) of 8 subjects each. Upon enrolment, each subject will be admitted to the study center and undergo serial PK sampling following a single dose of oral 744 30 milligrams (mg). Subjects will return to the clinic for follow-up evaluations 10-14 days after the 744 30 mg dose.
The LIMIT-Study is a placebo-controlled, double-blinded randomized controlled trial designed to explore the efficacy of a carrageenan-based lubricant as a topical microbicide for preventing HPV acquisition. Individuals at high risk for infection (men who have sex with men, or MSM, and especially those with HIV) will be included in the trial. Participants will complete a self-administered baseline questionnaire during the enrollment visit, and follow-up questionnaires during all other six visits. The shorter follow-up questionnaires are intended to evaluate recent sexual behaviours and to corroborate the responses given during the baseline visit. These questionnaires will measure HPV risk factors, compliance, and monitor safety and tolerability of the gels. Between follow-up visits, participants will be asked to log into a secure web module at least once a week to answer questions on daily sexual activities, condom and study gel use, and adverse events. Individuals will be screened for eligibility over the telephone or in person and eligible men will attend an enrollment visit, where the nurse will obtain informed consent and instruct the participant on gel use. They will receive a one month's supply of gel and provide the first specimen. Random number sets will be assigned to the treatment and control gel. Each participant will be assigned an individual code, which will be used to match him to the study arm. Lastly, the nurse will provide details about HPV infection and advice about condom use and sexual health. HPV infection status will be measured using anal specimens at baseline (enrollment/time 0), and at all follow-up clinic visits (1, 2, 3, 6, 9 and 12 months).
This is an observational safety and efficacy study on dihydroartemisinin-piperaquine in Timika, Indonesia with a 42 day follow up period.
This is a prospective Infection Control study comparing rates of antibiotic usage and infections in the General Intensive Care Unit (GICU) in beds with copper impregnated linens versus regular linens.
The overall goal of this Community Central Line Infection Prevention (CCLIP) trial, supported by grant R01 HS022870 from the Agency for Healthcare Research and Quality, is to determine whether use of a promising new intervention, namely 70% isopropyl alcohol embedded protective caps on central lines, in the home setting is associated with a reduction in ambulatory central line-associated bloodstream infections (CLABSI) in a high-risk population of pediatric hematology/oncology patients. Despite successes in CLABSI reduction efforts for inpatients, it remains unknown what generalizable best practices should be with chronic central lines in the home setting and how effective involving patients and caregivers across multiple institutions in CLABSI reduction efforts will be. This research will involve a cluster-randomized, cross-over design, clinical trial. This proposal will focus on the caregivers integral to ambulatory pediatric central line care: patients and families. The specific aims of the proposed research program are: Specific Aim #1: Evaluate whether use of 70% isopropyl alcohol embedded protective caps on central lines reduces the rate of CLABSI in ambulatory pediatric hematology/oncology patients. Hypothesis: Use of 70% isopropyl alcohol embedded protective caps on central lines will be associated with at least a 25% reduction in the ambulatory CLABSI rate for pediatric hematology/oncology patients. Specific Aim #2: Evaluate whether use of 70% isopropyl alcohol embedded protective caps on central lines reduces the rate of all positive blood cultures in ambulatory pediatric hematology/oncology patients. Hypothesis: Use of 70% isopropyl alcohol embedded protective caps on central lines will be associated with at least a 25% reduction in the positive blood culture rate at home for pediatric hematology/oncology patients. Specific Aim #3: Evaluate whether the use of 70% isopropyl alcohol embedded protective caps on central lines changes the distribution of bacteria isolated from blood cultures of pediatric hematology/oncology patients. Hypothesis: Use of 70% isopropyl alcohol embedded protective caps on central lines will reduce Gram-positive CLABSI, secondary blood steam infections, and single positive blood cultures at home for pediatric hematology/oncology patients.
The purpose of this study is to determine if the use of inhaled beclomethasone after a community-acquired respiratory viral infection in a lung transplant recipient decreases the risk of the subsequent development of chronic lung allograft dysfunction.
