Filter by:The acute respiratory infection is the fourth most common cause of hospital stay between elderly people. The purpose of this study is to evaluate the repercussion of hospital stay in hospitalized patients with a respiratory infection.
The main purpose of this study is to determine whether weekly oral vitamin D supplementation is effective to prevent acute respiratory tract infections in children. The hypothesis of the study is that vitamin D supplementation reduces the incidence and severity of acute respiratory tract infections in children.
This study assesses the seasonal of influenza vaccine effectiveness in adults hospitalised with laboratory-confirmed influenza through a network of hospitals in France. Also, To better understand the burden of other respiratory viruses such as respiratory syncytial virus (RSV) and SARS-CoV-2 in hospitalized adults, we need to describe and quantify the population hospitalized due to theses other respiratory viruses.
The TAILORED-Treatment consortium was established to develop new tools aimed to increase the effectiveness of antibiotic and antifungal therapy, reduce adverse events, and help limit the emergence of antimicrobial resistance in children and adults.
Acute illness is the most common presentation of children attending ambulatory care settings. Serious infections (e.g. meningitis, sepsis, pyelonephritis, pneumonia) are rare, but their impact is quite large (increased morbidity, mortality, induced fear in parents and defensive behaviour in clinicians). Early recognition and adequate referral of serious infections are essential to avoid complications (e.g. hearing loss after bacterial meningitis) and their accompanied mortality. Secondly, we aim to reduce the number of investigations, referrals, treatments and hospitalisations in children who are diagnosed with a non-serious infection. Apart from the cost-effectiveness, this could lead to less traumatic experiences for the child and less fear induction for the concerned parent. Finally, we aim to support the clinicians to rationalise their antibiotic prescribing behaviour, resulting in a reduction of antibiotic resistance in the long run.
This is a 5-year long-term follow-up study of open label, single-center, phase I clinical trial to evaluate the safety and efficacy of PNEUMOSTEM® in premature infants with bronchopulmonary dysplasia.
A phase I trial conducted in a single centre, observer-blind, randomized, dose-ranging, placebo-controlled study to evaluate the safety, tolerability, and immunogenicity of 2 intramuscular injections of plant-based H7 VLP Influenza Vaccine administered to healthy adults, 18-60 years of age.
Chronic exposure to (cigarette smoke) CS causes biological changes, including airway remodeling and changes in baseline gene expression profiles at the level of the epithelium. Our own data indicate that chronic exposure to CS suppresses the ability of epithelial cells to enhance antiviral gene expression in response to influenza infection and activate host defense responses. While there is a large body of evidence supporting the notion that exposure to CS causes significant changes in host defense responses, which may be linked to permanent changes in epithelial cells at the genomic level, it is not known whether new and emerging tobacco products have similar or distinct effects. Using live attenuated influenza virus (LAIV) inoculation in human volunteers, this study will compare influenza-induced responses in non-smokers (NS), cigarette smokers (CS), e-cigarette smokers (EC), hookah smokers (HS), and Little Cigar smokers (LCS) in vivo. This will be done by analyzing nasal viral titers, antiviral defense responses, inflammatory mediator production, and markers of immune responses for LAIV-induced responses between the different groups of volunteers.
The aim of this study is to determine performance characteristics of the FebriDx test in predicting viral or bacterial infection etiology among febrile (observed or reported) patients presenting the emergency department, urgent care centers or primary care offices with suspected acute respiratory tract infection.
The primary objective of this study is to evaluate the effectiveness of ingesting an alkylamide-rich echinacea root product (Quick Defense, Gaia Herbs) for 2 days immediately following each onset of acute respiratory illness (ARI) symptomatology during a 12-week period in the winter and early spring in women. Hypothesis: Subjects randomized to Quick Defense compared to placebo over a 12-week period will experience reduced ARI symptomatology, both acutely during each ARI episode and collectively over the entire 12-week study period.
