Filter by:Bronchiolitis obliterans (BO) is the well-known manifestation of the chronic pulmonary graft-versus-host disease(GVHD) after allogeneic hematopoietic stem cell transplantation (HSCT). The pathophysiology of BO is, however, poorly known. The available data strongly support the role of respiratory viruses, in particular paramyxoviruses (parainfluenzae virus (PIV), respiratory syncytial virus, metapneumovirus). It is likely that the alloimmune response triggered by the respiratory virus is inadequate and leads to the peribronchiolar fibrotic process. The objective is to analyze the kinetics of profiles of the blood and respiratory host responses resulting from a high or low parainfluenza respiratory infection, in order to evaluate if the occurrence of a BO is associated with a specific signature We will evaluate the predictive signature of a BO after a parainfluenza virus infection by characterizing the differences between the patients evolving and those not evolving to a BO at 2 months after the infection.
This study is a multi-center study with a minimum of three CLIA-waived intended operator sites in the United States in which prospectively self-collected vaginal specimens obtained from subjects who are symptomatic or asymptomatic for CT, NG, or TV will be evaluated with the Click Sexual Health Test in a Clinical Laboratory Improvement Amendments (CLIA) waived setting. Subjects interested in participating in this study will be assessed for eligibility and asked to give informed consent and assent, if applicable, by the Investigational Review Board (IRB). Only those subjects who meet the inclusion and exclusion criteria may be enrolled in the study.
A prospective randomized within-subject controlled study to compare the clinical performance of conventional autografting with and without the RECELL system on acute non-burn full-thickness skin defects.
Health care associated infection (HCAI) is a serious health hazard as it leads to increased morbidity and mortality of patients, length of hospital stay and costs associated with increased hospital stay. A total of 361 subjects divided into four groups were included in this study. The first group comprised of 179 doctors, the second had 31 nurses, third group had 110 OT Technicians and the fourth group included 41 subjects which included housekeeping staff and cleaners. Swabs were collected from OT staff at the time of entry and at exit from the OT. Places of swabs taken were: A) Web space, B) OT dress and C) Anterior nares.
In summary, in this project the investigators propose to study the proviral DNA genotyping to implement a lower cost and wider than the commercial systems currently in use, in order to analyze all HIV genes that are therapeutic targets of antiretroviral drugs. Using HIV proviral DNA we can obtain information for: HIV-1 Viral Tropism, Mutations associated to Integrase Inhibitors, Mutations associated to Transcriptase reverse Inhibitors, Mutations associated to Protease Inhibitors, and Mutations associated to GP41 Inhibitors. Along with this the investigators propose to validate the proviral DNA as starting material for genotyping which is independent of the patient's viral load and achieve a greater number of patients living with HIV have access to this important test that is essential in monitoring the HIV infection. 3.2 RESEARCH QUESTIONs Is proviral DNA a genetic compartment suitable for carrying out a genotypic resistance test in patients with low or undetectable viral load? Does proviral DNA have the same clinical validity that RNA? 3.3.- HYPOTHESIS A resistance genotyping test carried out by Proviral DNA detects the same mutations associated to resistance that viral RNA. 3.4.- OBJECTIVES: General/Specific General objective Develop a methodology to assess the proviral HIV-1 DNA or RNA as the genetic material for genotyping assays in genes that are targets of pharmacological interest as TR reverse transcriptase and protease (PRO), Integrase or GP41 Inhibitors and HIV tropism. Specific Objectives 1. Carry out genotyping by proviral DNA and compare it with the same genes genotyping performed with viral RNA. 2. Once the correlation between proviral DNA and RNA has shown, standardize a method to use the technique for clinical use in monitoring HIV patients according to each patient's needs. RNA for patients with viral load above 1,000 copies/mL. Proviral DNA for patients with low or undetectable viral load.
This study aims to evaluate the modifications in body composition and insulin resistance state in patients with grade II and III obesity included in an interventional lifestyle changes program and treated with probiotics (1 x 1011 CFU) or placebo for 16 weeks and its associations with intestinal microbiota behaviour
Elderly patients residing in nursing homes are particularly at risk of experiencing urgent medical problems needing admission to the Emergency Department (ED). This circumstance contributes to ED overcrowding, increases the risk of ward admission of elderly patients, and puts them at an even higher risk of hospitalization-related adverse events. The study hypothesis is that a complex intervention, delivered directly in nursing homes by hospital physicians in case of urgent medical problems, would contribute to reduce hospitalization of older nursing home residents. The intervention consists in a hospital-based "multidisciplinary mobile unit" (MMU), composed of a hospital specialist and a resident in emergency-urgency medicine who are coordinated by a senior physician serving as "flow manager". The team is active on work days, 8 am to 6 pm, and is activated by general practitioners of nursing homes, in case of urgent medical needs of one of the residents. The activation is made by a phone call to the "flow manager", who triages the clinical needs of the case. The output of the phone consultation may include therapeutic advice provided by phone, immediate on-site visit by the MMU team (specialist and resident), scheduled visit by the MMU team, or direct admission to the hospital unit where MMU is based, avoiding ED visits. The MMU team is provided with a portable ultrasound system, an essential set of drugs and medical devices useful in a urgency setting (central venous lines, nasogastric tubes, rectal tubes, bladder catheters). During on-site visits, the MMU team performs diagnosis, stabilization and therapeutic advice, with the mission of avoiding ED visits and hospital admissions whenever possible. The MMU intervention is already active in two nursing homes, since December 2018. The aim of this prospective, pragmatic, multicenter, quasi-experimental study (sequential design with two cohorts) is to test the effects of the implementation of the MMU care model in terms of reduction of unplanned hospitalization rates (primary outcomes), mortality, health service use and costs (secondary outcomes). Two nursing homes (i.e., the ones who already benefit from the intervention) will serve as study group, and two nursing homes with similar geographical location will serve as control group. All residents of the participating nursing homes will be eligible for study inclusion. The study will last for 18 months, and a number of 338 residents is planned for inclusion.
To evaluate the effect on quality of life of consumers with self-reported onychomycosis during the first 4 weeks of treatment in relation to the appearance of the infected toenail.
The current study is a pilot study to assess the feasibility of a superordinate project. The final objective of this superordinate project is to describe and model the pharmacokinetic behaviour of a small number of standard antimicrobials used in the treatment of frequent blood stream infections, and to link this via pharmacodynamic models to (inhibition of) bacterial or fungal growth as well as to clinical outcomes in patients.
Diabetic foot problems, especially infections (DFI), require multiple resources including iterative surgeries and amputations, long-lasting antibiotic therapies, education, off-loading and eventually revascularization and appropriate foot-ware. Treatment is complicated, multidisciplinary, and marked with a high risk of recurrences. This is a retrospective and prospective cohort with side studies of pathologies and academic research questions that cannot be separated from each other. The investigators establish a retro-and prospective cohort of diabetic foot problems (ambulatory and hospitalized patients) and perform side studies to reduce the incidence of complications, and to reduce recurrences of DFI, cost and adverse events related to therapies. Cohort: Prospective and retrospective cohort of all diabetic foot problems with emphasis on surgical and infectious variables. Trial 1 (Randomized trial on residual infection after amputation): Determination of the level of amputation per MRI followed by a randomization concerning the duration of post-amputation systemic antibiotic therapy, if there is residual bone infection. Trial 2 (Randomized trial on infection without amputation): Determination of the duration of systemic antibiotic therapy in diabetic foot infections without Amputation of the infection.
