Filter by:This is a longitudinal, prospective observational study focusing on health-related outcomes relative to potential changes in the respiratory microbiome seen with weekly SARS-CoV-2 testing in nursing home residents.
Pilot study to evaluate the feasibility of a pilot embedded pragmatic cluster randomized controlled trial to reduce the duration of antibiotic therapy and number of antibiotic prescriptions in nursing home residents with AD/ADRD.
This study is being conducted to assess the performance of the BD Veritor™ Plus System for Rapid Detection of SARS-CoV-2, used in serial testing, in identification of infectious, asymptomatic individuals. This information may be used to inform development of an effective testing strategy by policy makers.
Otitis media is more common in young children and it is estimated that 75% of all children experience at least one episode before the age of three. Otitis media is one of the common pediatric diagnoses and recurrent episodes account for the most commonly performed surgical procedure. Despite this a high degree of inaccuracy exists in diagnosis of this condition which depends on subjective assessment of the ear drum via direct visualization using an otoscope. Researchers can use LED-based multi wavelength light absorption and scattering measurements for the analysis of ear drum and the middle ear.
The purpose of this study is to assess SARS CoV-2 infection, viral shedding, and subsequent potential transmission in individuals immunized with the Moderna COVID-19 vaccine.
The primary objective of this study is to evaluate the safety and tolerability of a combination of the broadly neutralizing antibodies (bNAbs) teropavimab (formerly GS-5423) and zinlirvimab (formerly GS-2872) in combination with the HIV capsid inhibitor lenacapavir (LEN).
The study aims to evaluate the safety and efficacy of a 2 drugs ART regimen (lamivudine plus dolutegravir) for prevention of mother to child transmission in pregnant women with HIV. 20 pregnant women will be enrolled in this proof of concept protocol. They will be prescribed DTG-3TC (fixed-dose combination), and will be followed up to the end of gestation. Initially, a total of 10 pregnant women will be recruited for the first phase of the study. Once the first phase is successfully completed, 10 additional participants will be included in a second step.
This is a randomized study that sought to analyze the diagnostic accuracy of the telemedicine consultation of patients suspected of respiratory tract infections during COVID-19 pandemic in comparison with the face-to-face evaluation at the emergency department.
This is a Phase I/IIa trial designed to evaluate topical bacteriophage therapy in patients with diabetic foot ulcers.
Exacerbations, in particular during chronic Pseudomonas aeruginosa (PA) infection, are very important in the prognosis of patients with non-cystic fibrosis bronchiectasis (BE). In Cystic Fibrosis patients, PA biofilms are associated with chronic respiratory infections and are the primary cause of their increased morbidity and mortality. However, the presence and role in exacerbations of PA biofilms, microbiome dysbiosis and inflammatory biomarkers has not been studied in depth in BE patients. Our aim is to determine the association between PA chronic infection and its biofilms with the number of exacerbations in the next year (primary outcome), time until next exacerbation, quality of life, FEV1 and inflammatory biomarkers (secondary outcomes) in BE patients with or without chronic obstructive pulmonary disease (COPD). The investigators will include and follow up during 12 months post study inclusion, 48 patients with BE and 48 with BE-COPD, with a positive sputum culture of PA. During stability and follow up (and in each exacerbation) The investigators will collect 4 sputum, 4 serum samples, perform spirometry, and quality of life tests every three months. For the biomarkers subproject, 4 additional serum samples will be collected at: exacerbation, 3-5 days after treatment, at 30 days and three months post-exacerbation. Biomarkers will be measured by commercial kits and Luminex. The investigators will quantify PA colony forming units (CFU)/mL, their resistance pattern, their mutation frequency and isolate mucoid and non-mucoid colonies. In each sputum, the investigators will analyze by Confocal Laser Scanning Microscopy (CLSM) and Fluorescent in situ Hybridizatrion (FISH) PA biofilms, their size, bacterial density and their in situ growth rate. Specific serum antibodies against PA will be determined through Crossed Immunoelectrophoresis. In addition, the investigators will indentify potential respiratory microbiome and gene expression patterns predictive for exacerbations, or with a protective role against chronic PA infection, as well as their association with biofilms. Microbiome analysis will be performed through the Illumina Miseq platform. Finally, the investigators will explore the antimicrobial activity of novel combinations of antibiotics against PA, both in in vitro planktonic cultures and in a biofilm model, and will include testing of antibiotic-containing alginate nanoparticles.
