Filter by:The purpose of this study is to demonstrate that viral specific T-cells (a type of white blood cell) can be generated from an unrelated donor and given safely to patients with viral infections.
This non-interventional study aims to characterize the cells infected with HIV over time in different types of vagino-uterine tissue.
This phase II trial studies how well donor cytotoxic T lymphocytes work in treating patients with malignancies with BK and/or JC virus. Cytotoxic T lymphocytes are made from donated blood cells that are grown in the laboratory and are designed to kill viruses that can cause infections in transplant patients and may be an effective treatment in patients with malignancies with BK and/or JC virus.
This is an open-label dynamic whole-body PET/CT (positron emission tomography/computed tomography) study for investigation of radiation dosimetry, plasma pharmacokinetics, biodistribution, safety and diagnostic performance of 18F-FDS in healthy volunteers and patients with suspected infection. A single dose of nearly 370 MBq 18F-FDS will be intravenously injected into healthy volunteers and patients with suspected infection. Visual and semiquantitative method will be used to assess the PET/CT images. Changes of blood pressure, pulse, respiration, temperature, routine blood and urine tests, serum alanine aminotransferase, albumin, and creatinine, and any adverse events will be collected from the volunteers. Adverse events will also be observed in the patients.
Background: - Inflammation is how the body reacts to infection or injury. Infections or inflammation in the brain and nerves can be serious. There aren t always good tests to detect this. Researchers want to learn more about how diseases affect the brain and nerves to develop better tests and treatments. Objective: - To learn more about how inflammation and infections hurt the brain and nervous system. Eligibility: - People at least 2 years old with a diagnosis or suspected diagnosis of nervous system infection or inflammation. Design: - For some participants, a clinician outside of NIH will collect blood, tissue, and other samples. These will be sent to NIH and analyzed. - Other participants will have several visits to NIH. Children may not have all these tests. - Participants will have: - Medical history. - Physical and neurological exam. - Blood and urine samples collected. - Saliva collected. They will chew on a piece of sterile cotton for one minute. - Magnetic resonance imaging (MRI) scan. The scanner is a metal cylinder in a strong magnetic field. Participants will lie on a table that slides in and out of the cylinder. Participants will get a contrast agent through an intravenous (IV) catheter during the MRI. A needle will be used to guide a thin plastic tube (catheter) into an arm vein. - Lumbar puncture. Skin will be numbed and a needle will be inserted into the space between the bones in the back. Fluid will be removed. - Some participants may have optional study procedures. These may include eye tests, memory and thinking testing, tests with electrodes on the head, or skin biopsy.
Implantable venous access port infections are mainly due to coagulase negative staphylococci and may be managed by antibiotic lock therapy with retention of the port. Most of the time a vancomycin lock is used. Experimental data show that vancomycin may be poorly effective in eradicating the staphylococcal biofilm in the port. Another disadvantage of Vancomycin-containing lock solution is the occurrence of resistant organisms and the risk of catheter occlusion. Ethanol-containing lock solution is highly effective in vitro and does not expose to the risk of emergence resistance.
This is a prospective, randomized, blinded clinical trial to determine if the Air Barrier System device reduces the incidence of surgical site infection after total hip replacement, acetabular repair, posterior spinal fusion, and prosthetic vascular graft procedures.
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 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
The great diversity of regimens and treatment lines, the different efficacy of these, mostly due to the increase in bacterial antibiotic resistance and regional differences, requires a continuous critical analysis of clinical practice, evaluating systematically the efficacy and safety of the different regimens and the cost-effectiveness of the different diagnostic-therapeutic strategies. This will help in the design of an efficient and optimized treatment that will reduce number of re-treatments, diagnostic tests and the appearance of associated pathologies such as peptic ulcers, gastrointestinal bleeding and, probably, gastric cancers. Therefore, the evaluation of real clinical practice using non-interventionist registries will help to improve the design and organization of European Consensus on the management of H. pylori infection, which is the best way to establish healthcare efficiency. Primary aim To obtain a database registering systematically over a year a large and representative sample of routine clinical practice of European gastroenterologists in order to produce descriptive studies of the management of H. pylori infection. Secondary aims 1. To evaluate H. pylori infection consensus and clinical guidelines implementation in different countries. 2. To perform studies focused on epidemiology, efficacy and safety of the commonly used treatments to eradicate H. pylori. 3. To evaluate accessibility to healthcare technologies and drugs used in the management of H. pylori infection. 4. To allow the development of partial and specific analysis by the participating researchers after approval by the Registry's Scientific Committee Methodology Non-interventionist prospective multicentre international registry promoted by the European Helicobacter Study Group. A renowned gastroenterologist from each country was selected as Local Coordinator (30 countries). They will in turn select up to ten gastroenterologists per country that will register the routine clinical practice consultations they receive over 10 years in an electronic Case Report Form (e-CRF). Variables retrieved will include clinical, diagnostic, treatment, eradication confirmation and outcome data. The database will allow researchers to perform specific subanalysis after approval by the Scientific Committee of the study.
