Filter by:The Vancomycin Study is a multi-center, prospective randomized controlled trial that will compare the proportion of deep surgical site infections within 6 months in patients treated with local Vancomycin powder compared to those treated without local Vancomycin powder at the time of fracture fixation.
This study is being implemented to identify the role of prophylactic use of ethanol lock in adult patients on home parenteral nutrition (HPN). Central catheter related blood stream infection is a major complication in patients on HPN. The investigators hypothesize that the prophylactic use of ELT will decrease the number of catheter related blood stream infections compared to the control group. The investigators further hypothesize that with the introduction of prophylactic ELT, the number of infections will decrease.
This study is to evaluate the antiviral efficacy, safety, and tolerability of combination therapy with ledipasvir/sofosbuvir (LDV/SOF) fixed-dose combination (FDC) + vedroprevir (VDV) ± ribavirin (RBV) for 8 weeks in treatment-experienced adults with chronic genotype 1 hepatitis C virus (HCV) infection and cirrhosis.
The purpose of this study is to know the effects of probiotics on the incidence of Necrotizing Enterocolitis (NEC) in preterm infants less than 1500 g.
In the Netherlands about 18,000 surgical procedures with implant removal are annually performed after fracture healing, of which 30-80% concern the foot, ankle and lower leg region. For clean surgical procedures, the rate of postoperative wound infections (POWIs) should be less than 5%. However, rates of 10-12% following implant removal, specifically after foot, ankle and lower leg fractures are reported. Currently, surgeons decide individually if antibiotics prophylaxis is given, since no guideline exists. This leads to undesirable practice variation. Therefore, the investigators propose a double-blind randomized controlled trial (RCT) in patients scheduled for implant removal following a foot, ankle or lower leg fracture, to assess the (cost-)effectiveness of a single gift of antibiotic prophylaxis. Primary outcome is a POWI within 30 days after implant removal. Secondary outcomes are quality of life, functional outcome at 30 days and 6 months after implant removal and costs. With 2 x 250 patients a decrease in POWI from 10% to 3.3% (expected rate in clean-contaminated elective orthopedic trauma procedures) can be detected (Power=80%, 2-sided alpha=5%, including 15% lost to follow up). If the assumption of the investigators, that prophylactic antibiotics prior to implant removal reduces the infectious complication rate, is confirmed by this RCT, this will offer a strong argument to adopt a single gift of antibiotic prophylaxis as standard practice of care. This will reduce the incidence of POWIs and consequently will lead to less physical and social disabilities and health care use. In addition, it will decrease the rate of use of empiric broad-spectrum antibiotics (and antibiotic resistance) prescribed upon suspicion or diagnosis of a POWI. A preliminary, conservative estimation suggests yearly cost savings in the Netherlands of €3.5 million per year.
Background: Tuberculosis (TB) is a severe disease and a major cause of death in many people worldwide. It is caused by a bacteria that enters through the lungs and can spread elsewhere in the body. People with latent TB have the bacteria that lie dormant but can become active and cause disease. These people are offered treatment to prevent development of active TB. Worldwide, a lot of people with LTBI also have a parasitic worm called a helminth that can stay in the gut or the blood. These parasites can affect the immune system and cause diseases like TB to become worse. Researchers want to see how helminth infection makes it harder for people to fight TB infection. Objectives: - To study how the immune system of people with latent tuberculosis infection (LTBI) acts to prevent development of active TB. Also, to study how helminth infection might affect this immune response. Eligibility: - Adults age 18 70 with LTBI as defined by an approved blood test called QuantiFERON TB Gold. - No evidence of infections like Hepatitis or HIV - Pregnant subjects and subjects taking medications that suppress the immune system are not eligible. - Have not received prior treatment for LTBI. Participants might be still eligible if prior treatment for active TB has been received Design: Screening phase: - Participants will be screened with medical history, physical exam, and blood tests for other infections/conditions which might affect the immune system. They will have testing for active TB i.e. blood testing as well as testing of their spit, scans and X-rays. Baseline phase: - Only eligible participants will be entered into the study. - Participants will have interviews, medical history, and physical exam. - Blood will be drawn from an arm vein for testing. - Participants will collect stool samples at home for 3 days in a row to test for helminth infection.. - Participants may have apheresis. Blood cells are removed by needle. They pass through a separator machine which returns everything but the cells back to the participant. - Participants may have procedures at the start and end of the study that let researchers look into the lungs and collect cells. Study phase, about 2 years: - All participants will be offered treatment for LTBI which lasts 6-9 months. - Participants being treated for LTBI will have about 11 study visits. They will visit monthly for 9 months while on treatment, then 6 and 12 months after treatment. - Participants not eligible/refusing treatment for LTBI will be made aware of active TB, then have 3 other visits, about 6, 12, and 24 months after the baseline visit. - Participants who have helminth infection will receive appropriate treatment. - All participants will have blood drawn at each visit.
This was a single-center study using induced blood stage malaria infection to characterize the activity of ACT-451840 against early Plasmodium falciparum blood stage infection
The aim of this study is to conduct an Asia-Pacific, multi-center, prospective observational study to characterize patients with CDI as well as to understand treatment and management of the disease.
The microbiota represents the collections of microbial communities that colonize a host. In health, the microbiota protects against pathogens and maturation of the immune system. In return, the immune system determines the composition of the microbiota. Altered microbial composition (dysbiosis) has been correlated with a number of diseases in humans. The real role of the microbiota in transplant recipients is still unknown even though we suspect that it may be affected directly or indirectly by immunosuppressive drugs and antimicrobial prophylaxis taken by transplant patients, as well as by inflammatory process secondary to ischemia/reperfusion injury. A number of studies have investigated the impact of liver transplantation on the intestinal microbiota. In a recent analysis of stool flora (Microb Ecol 2013; 65: 781-791) in 12 liver transplant recipients, changes in the microbiota were correlated to post-transplant infections. The authors suggested that the shift to pathogenic strains of bacteria due to the use of prophylactic antibiotics may be contributing to post-transplant complications. In a larger study, Wu et al (Hepatobiliary Pancreat Dis Int 2012; 11: 40-50) demonstrated marked changes in the gut microbiota post-transplantation with an increase in Enterobacteriaceae and Enterococcus, and reduction in Eubacteria, Bifidobacterium and Lactobacillus species. These changes, however, resolved over time such that by 6 months, at times when bacterial prophylaxis ends and immunosuppression is reduced. A better characterization of the impact of post-transplant therapy on the human microbiota has the potential to improve our understanding of the infection process and translate into development of new therapeutic strategies. The main goal of this study is to characterize intestinal microbiota and confirm the same bacterial DNA in peripheral blood and portal lymph nodes in patients affected with end-stage chronic liver disease, and to analyze its evolution from the moment of inclusion in waiting list throughout the first year after liver transplantation. For each patient, a healthy CONTROL with a similar age (± 10 years) will be selected from the same family setting, in whom just one sample will be obtained during the enrollment phase. The second goal is to analyze the potential associations between microbiota flora and transplant outcomes during the same period.
Hand hygiene is the single most effective practice in preventing the spread of hospital-acquired infections. Despite the strength of the evidence, hospital staff continue to sanitize their hands less than half of the time required by guidelines. Effective interventions are needed to improve hand hygiene compliance rates among hospital staff, but most are of poor quality and do not examine the specific effects of individual interventions. This study will build a "bundle" of three hand hygiene interventions using a research design that allows for the effectiveness of each intervention to be measured individually and combined.
