Filter by:The empirical use of vancomycin in combination with a broad-spectrum beta-lactam is currently recommended after the initial surgery of prosthetic joint infection (PJI). However, the tolerability of such high-dose intravenous regimens is poorly known. T
iSpecimen aims to create a clinical partner network of hospitals, laboratories, academic institutions, and other healthcare organizations ("institutions") capable of providing researchers and educators ("researchers") with annotated biospecimens for use in biomarker discovery and validation; diagnostic test and instrumentation development and validation; therapeutics development; other medical research including the impact that various specimen collection and handling methods and conditions have on research results; and in education such as researcher or physician training (collectively "research").
This study evaluates the effectiveness of a new intervention, fluoroquinolone (FQ) Preprescription Authorization (PPA) strategy, to reduce and prevent Clostridium difficile infection (CDI) in hospital intensive care units (ICUs). The investigators will model a successful FQ PPA strategy in several Wisconsin ICUs and compare whether the intervention has improved outcomes in reducing CDIs. An additional goal of the study is to evaluate environmental and work system factors using systems engineering models in order to determine the most successful way to implement these new strategies.
People living with HIV (PLWH) often have poor sleep, which may put them at a higher risk for many chronic diseases, including cardiovascular disease. One of the mechanisms by which this may occur is via chronic inflammation and endothelial dysfunction. Adenosine plays an important role in sleep homeostasis, with levels increasing in the CSF in response to sleep deprivation and falling with sleep. Peripherally, adenosine, via its signaling pathway, plays an important role in immunoregulation by suppressing the inflammatory response. PLWH, even on antiretroviral therapy, have suppressed peripheral adenosine levels which are predictive of adverse cardiovascular outcomes. The hypothesis underlying this study is that acute sleep deprivation in PLWH does not result in a compensatory increase in extracellular adenosine and its signaling peripherally, and this failure to appropriately compensate, leads to an increase in systemic inflammation and endothelial dysfunction.
One-step exchange arthroplasty is more and more used in the treatment of chronic infections, especially in patients at risk anesthetic. This strategy is not recommended in patients infected with multidrug-resistant organisms or difficult to treat because of a risk of bacterial persistence on the new implant. Antibiotic pretreatment by a narrow-spectrum molecule and for which resistance acquisition is difficult might be of interest to try to reduce the inoculum and avoid contamination of the new implant.
At Rigshospitalet, Denmark, we will examine the immune function of solid organ transplant recipients before and at several timepoints after transplantation as well as the clinical outcome, especially the risk of infections complications and graft rejections. The immune function will be assessed with a complete immunological profiling consisting of immune phenotype (flow cytometry), immune function (TruCulture®) and circulating biomarkers. The study aims to generate prediction models of patients at excess risk of poor clinical outcome, with the ultimate intent to propose personalized immunosuppressive regimes to be tested in future randomized clinical trials.
The purpose of this study is to evaluate the use of a blood test: Karius® plasma-based next-generation sequencing test (Karius Test), to see if we can detect and measure the infection causing agent in children with musculoskeletal infections (MSKI).
This is a double blind, randomized, placebo-controlled, parallel design, study in which 24 HIV-infected participants with durable viral suppression will be randomly assigned to receive vaccination with MVA.tHIVconsv3 (M3), MVA.tHIVconsv4 (M4), M3+M4 combined, or placebo. Participants will be randomized 7:7:7:3 to one of four study arms, and receive study treatment or placebo at Day 0. Each enrolled participant will complete the study in approximately 33.5 weeks (8.4 months). The purpose of this study is to find out: - If it is safe for people to receive injections of two investigational HIV vaccines, called MVAtHIVconsv3 and MVAtHIVconsv4 alone or in combination. - If giving participants these vaccine doses will increase their immune system's ability to kill HIV virus.
Annually, more than 250,000 patients in the U.S. with end-stage heart failure stand to benefit from ventricular assist device (VAD) therapy. 60% of patients develop a healthcare-associated infection (HAI) within 90-days of implantation. The investigators long term goal is to develop and subsequently promote wide-scale adoption of evidence-based HAI prevention practices following durable VAD implantation. This will be done by addressing the following aims: Aim 1. Identify determinants of center-level variability in HAI rates. Aim 2. Develop a comprehensive understanding of barriers and facilitators for achieving low center HAI rates. Aim 3. Develop, iteratively enhance, and disseminate a best practices toolkit for preventing HAIs that accommodates various center contexts. The investigators will use a focused survey of U.S. VAD centers to identify determinants of center variation in 90-day HAI rates: - Process Factors (e.g., intranasal mupirocin), - Provider Factors (e.g., surgeon technique), - Device Factors (e.g., centrifugal vs. axial), - Center Factors (e.g., provider communication). Understanding the barriers and facilitators within individual centers for maximizing adoption of prevention measures would serve as the foundation for targeted improvement strategies. Without this knowledge, evidence-based, action-oriented recommendations will have limited local adoption and ultimately effectiveness in preventing HAIs after VAD implantation.
Death and vascular tears occur in up to 1% of the patients undergoing lead extraction procedures. These complications are due to abnormal force vectors during the procedure. The investigators postulate that use of bidirectional traction (superior and inferior directions) and feedback from a digital force gauge is associated with minimal lead displacement compared to conventional lead extraction. Lead displacement is an indirect risk factor for potentially fatal lead extraction complications
