Filter by:Rationale and Background: Since 2013, Butantan Institute has been performing passive pharmacovigilance activities related to its triavalent, fragmented and inactivated vaccine (IB TIV). Objetive: To conduct an active surveillance study focusing on the elderly and health care professionals as part of Butantan pharmacovigilance plan, while passive surveillance activities will continue. The pharmacovigilance plan, via active surveillance, is being implemented in response to WHO requirements for pre-qualification of IB TIV.
LRTI (Lower respiratory tract infection) is a severe disease in China. The fast and accurate diagnosis of pathogens, bacteria or viruses that cause the infection is critical for the therapy. In this study, investigators assume that the use of FilmArray Respiratory Panel will provide more rapid and comprehensive evidences to physicians to diagnose LRTI which is caused by viruses or atypical pathogens and then reduce the length of antibiotics use by 0.5-1.0 days as well as other hospital resources (length of hospital/ICU stay, take-away oral antibiotics, etc.). Secondly, investigators assume that in LRTI patients with viral infection and a low serum PCT level, fewer length of antibiotics use can be expected. Thirdly, the use of FilmArray Respiratory Panel will provide clearer epidemiology data of virus and atypical pathogens in hospitalized LRTI patients.
The purpose of this study is to assess the duration of the viral shedding in hematology and oncology patients after a respiratory tract viral infection. This duration has not been much studied in that population whereas it is probably longer than that in immunocompetent patients. Thereby it may be a source of transmission amongst these immunocompromised patients.
Background: One of the main causes of respiratory infections in children and adults is RSV. This stands for respiratory syncytial virus. Healthy adults usually get a cold when they get an infection with RSV. They generally recover without any problems. But some infections can be life-threatening. Researchers want to study RSV infection in a safe, controlled setting in healthy adults to help develop new treatments. Objective: To test the safety of a high dose of RSV A2 by spraying the virus into the nose, and studying how the body responds. Eligibility: Healthy adults ages 18-50 Design: Participants will be screened during 2 screening visits with: - Medical interview - Physical exam - Blood and nasal samples - Chest X-ray (chest radiograph) - Participants will have a heart test. Sticky patches on the body will detect heart electrical activity. - Pulmonary function test (PFT). They will blow into a machine to measure airflow. - Urine tests for pregnancy or drug use. Participants will be admitted to the hospital before they get RSV A2. Participants will get a single dose of RSV A2 as two sprays, one into each nostril. Participants will stay in the hospital under isolation for as long as it takes the body to clear RSV A2 from nasal fluids. This can take as long as 14 days or more. Participants cannot take any cold medicine to try to feel better. Every day, participants will: - Answer questions about their symptoms - Have nasal washes and/or nasal swabs collected - Have a physical exam Participants will have blood drawn most days. After discharge, participants will keep a health diary. Participants will have 2 follow-up visits at 1 month and 2 months after receiving the RSV A2 dose. A history and physical examination, a blood draw, and nasal wash and swab will be performed.
Antibiotic resistance is an increasingly serious problem in Switzerland which is associated with the exposure and overall uptake of antibiotics in a population. Reduced antibiotic prescribing for outpatients is paralleled by a decrease in antibiotic resistance rates. In a recent pragmatic trial, the investigators found only promising yet not very conclusive results as those were present only in some groups. This nationwide antibiotic stewardship program with routine feedback on antibiotic prescribing was not associated with an overall change in antibiotic use. In older children, adolescents, and younger adults fewer antibiotics were prescribed, but not consistently over the entire intervention period. Hence, the investigators now aim to evaluate a better-tailored program to obtain a better understanding of the effects on patient-relevant outcomes, antibiotic resistance, and the underlying mechanisms leading to different effects in certain subgroups of patients. The investigators plan to evaluate a nationwide antibiotic stewardship program combining routine prescription feedback with the provision of physician and patient education material for primary care physicians in Switzerland. The project is conducted within the framework of the National Program on antimicrobial resistance by the Swiss National Science Foundation. Also, additional subprojects will be done where we will assess the impact of COVID-19 on AB prescription by comparing the years 2017,2018, and 2019 with the year 2020 data.
The purpose of this study is to evaluate the efficacy, tolerability, and safety of BEZ235 alone and in combination with RAD001 to support further development to reduce the incidence of respiratory tract infections (RTIs) in elderly subjects.
This is a performance study to test the sensitivity and specificity of the BioFire FilmArray Lower Respiratory Tract Infection (LRTI) Panel. The purpose of this study is to prospectively collect and test residual Bronchoalveolar lavage (BAL) and sputum specimens and generate performance data to support regulatory classification of the FilmArray LRTI as an in vitro diagnostic (IVD) in the US, European Union (EU), Canada, and other regions.
Pediatric patients between 6months and 6years old will be included. They are scheduled for elective general or urologic surgery at a single tertiary medical center. Before the operation, the researcher interviews the parents of the pediatric patients to check whether they have the upper respiratory tract infection and asks them to fill out a questionnaire about the severity of their symptoms. The researcher will get the symptom score of the upper respiratory tract infection in the questionnaire. The degree of anesthesia induced atelectasis is measured using lung ultrasound. Pulmonary ultrasound is performed after endotracheal intubation and at the end of the operation dividing the patient's thorax into 12 regions. The investigator grades the degree of atelectasis at each region form 0 to 3 points. After the end of the operation, check whether the respiratory adverse effects occurred during emergence and recovery at the post anesthesia care unit.
Antimicrobial resistance is one of today's most urgent public health problems. One of the most important strategies to slow the spread of antimicrobial resistance is the promotion of judicious antimicrobial use. There are tremendous opportunities to reduce unnecessary antimicrobial-prescribing, particularly in Emergency Departments (EDs). In this study, the investigators will work collaboratively with ED providers in the Veterans Health Administration (VHA) to reduce unnecessary antimicrobial use. Academic-detailing and an audit-and-feedback intervention will be implemented, and the study will assess how overall antimicrobial-prescribing changes once these interventions are performed. ED providers will be shown how their antimicrobial-prescribing compares to their peers, thereby encouraging them to consider their professional reputation when making prescribing decisions. To assess the impact of this intervention, the study will monitor providers' antimicrobial-prescribing behavior through an automated metric, i.e. number of antimicrobial prescriptions per number of patient-visits. To assess changes in the appropriateness of antimicrobial-prescribing, the study team will also perform manual chart reviews and compare prescribing decisions to published guidelines.
This is a randomized, double-blinded, placebo-controlled, non-inferiority multicenter clinical trial of azithromycin vs. placebo in adults presenting as outpatients with suspect Lower Respiratory Tract Infection (LRTI) and a Procalcitonin (PCT) level of < / = 0.25 ng/mL, as a strategy for reducing antibiotic prescriptions. The study is designed to compare the efficacy of azithromycin versus placebo on Day 5 (i.e., after 4 days of treatment) in subjects with suspect LRTI and PCT levels of < / = 0.25 ng/mL at enrollment using a non-inferiority approach. The study will recruit potential subjects 18 years of age or older who are suspected to have LRTI. The enrollment cap will be 840 participants, for the goal of approximately 674 randomized participants who will be randomized 1:1 to receive oral azithromycin or placebo for five days. Randomized subjects will have efficacy measured from the time of the first dose of study drug (Day 1) through approximately Day 28. The Primary Objective is to compare the efficacy of azithromycin versus placebo on Day 5 (i.e., after 4 days of treatment) in subjects with suspect LRTI and PCT levels of < / = 0.25 ng/mL at enrollment using a non-inferiority approach.
