Filter by:The study titled " The Effect of Definitive Identification of Viral Etiology in Emergency Department Patients with Acute Respiratory Infection on Antibiotic Utilization (RADIATE)" aims to investigate the effectiveness of a rapid diagnostic approach in reducing unnecessary antibiotic use in the emergency department (ED) for patients presenting with acute respiratory illness (ARI) due to a virus. Using a prospective design, eligible participants are individuals who visit the ED with complaints related to acute respiratory illness. The study will employ a single-arm consecutive enrollment approach. The intervention involves the implementation of a rapid point-of-care multiplex polymerase chain reaction (PCR) test to promptly identify the viral cause of the infection. By utilizing a rapid diagnostic tool to identify viral etiology, the study aims to provide healthcare professionals in the ED with more accurate information to guide treatment decisions. Ultimately, the goal is to decrease the unnecessary use of antibiotics for ARI's due to a virus, which has several negative outcomes including promotion of antibiotic resistance, exacerbating ED length of stay and encouraging unnecessary additional diagnostic tests.
Vapendavir (VPV) is a drug being developed to treat human rhinovirus (RV) infection, one virus responsible for the common cold. Vapendavir prevents the virus from entering cells and making more infectious copies of itself. A study is being planned to investigate VPV in patients with chronic obstructive pulmonary disease (COPD, a lung disease making it difficult to breathe) who develop a rhinoviral infection; however, VPV has not been approved for use in treating any indication (disease) by the FDA or any other global regulatory agency. Therefore, VPV is considered investigational, and the study doctor is conducting this investigational research study. Safety will be monitored throughout the entire study.
The goal of this observational study is to learn about infectious complications in patients affected by B-cell acute lymphoblastic leukemia treated with inotuzumab-ozogamicin (INO). The main question it aims to answer is: • incidence of infectious complications (bacterial, fungal, viral) in patients receiving inotuzumab ozogamicin up to 60 days after the end of treatment
The goal of this randomized clinical trial is to test the efficacy of high efficiency particulate air (HEPA) cleaners in reducing respiratory viral exposure and infections in elementary school classrooms. Classrooms will be randomized to active vs. sham HEPA cleaners. The main questions it aims to answer are: - Do classroom HEPA cleaners reduce exposure to viruses? - Do classroom HEPA cleaners reduce student and teacher infections? - Do classroom HEPA cleaners reduce infections in family members?
The goal of this randomized clinical trial is to investigate the optimal supportive treatment of bronchiolitis in infants from 0-12 months of age. The main question[s] it aims to answer are: - To investigate whether isotonic saline should be used as supportive treatment for children with bronchiolitis, and if so, identify the optimal route of administration. The primary outcome is duration of hospitalization. - To investigate the current epidemiology of the viral pathogens causing bronchitis in children in Denmark, and to assess whether children infected with specific pathogens might benefit from treatment with isotonic saline. The children are randomized after inclusion through computer randomization to one of the 3 arms in the study: 1. Nebulized isotonic saline 2. Nasal irrigation with isotonic saline 3. No treatment with saline The investigators will compare treatment with saline (both methods) with no treatment, and the investigators will also compare the two methods of delivery of saline (nebulized vs. nasal irrigation).
The fast increase of Multidrug-resistant microorganisms (MDRO) due to the high amount of antimicrobials being poorly used may be limited by better regulating antimicrobial usage globally. The goal of this observational study is the performance of the MeMed BV® test in the MeMed Key® device at the emergency department to a) support the differential diagnosis between bacterial and viral infections of the respiratory tract and b) provide evidence of how the use of this test may limit gut colonization by MDRO.
The goal of this interventional study is to learn about nasal microbiome and viral infections in newborns hospitalised in neonatology. The main questions it aims to answer are : - how often are newborns infected by viruses in neonatology ? - how does the microbiome develop during first weeks of life ? - how does microbiome and viruses interacts together ? - is there a link between viral infection, microbiome, and medical complications during hospitalisation in neonatology ? Participants will have a nasal swab taken each week during their hospitalisation in neonatology, and researchers will take medical data from the medical chart.
The goal of this observational analytic study with a cohort desing is to evaluate the epidemiology, risk factors and clinical phenotype of headache during Influenza infection. The study will be done in collaboration with the Healthcare Sentinel Network of Castile and Leon (Red Centinela Sanitaria de Castilla y León, RCSCYL) and the National Influenza Center of Valladolid (CNGV). First, the historical data of the VIGIRA network of the 2010-2022 flu seasons will be analyzed, assessing the epidemiology and risk factors of headache during Influenza infection; and second, a study with a case series design with prospective follow-up will be carried out for the incident cases of the 2022-2023 and 2023-2024 Influenza seasons, evaluating the clinical phenotype and the duration of the headache.
Patient admitted in intensive care unit (ICU) for acute infection whether it be viral or bacterial had major impairment of the immune response. One hallmark of the immune impairment is presence of immature granulocyte (IG) in blood. Depend of initial trigger (virus or bacteria) concentration, phenotype and function of IG seems to be different. In this prospective trial, immature granulocytes will be analyzed in depth in immunocompetent patients hospitalized in the intensive care unit for an acute viral or bacterial infection.
The purpose of this research study is to identify the effects of 2 over-the-counter mouthwashes on bacteria and 3 viruses in the participant's mouth and gut. The participant will be randomly allocated to rinse their mouth twice daily either with Listerine mouthwash, Lumineux Oral Essentials mouthwash, or water. The overall duration of the study will be approximately 180 days and will include approximately 5 visits and 15-30 minutes for each visit with a total of approximately 2.5 hours of your time. Additionally, fecal matter will also be collected in some subjects using a commercial collection kit.
