Filter by:The purpose of the current study is to test different interventions to determine the most effective way to promote flu vaccine uptake in a high-risk population identified by an "artificial intelligence" (AI) or machine learning (ML) algorithm. The specific aims are: 1. Evaluate the effect on flu vaccination rates of informing health-system patients who are identified by an ML analysis of EHR data to be at high risk for flu complications that they are at high risk with either (a) no additional explanation, (b) an explanation that this determination comes from an analysis of their medical records, and (c) the additional explanation that an AI or ML algorithm made this determination. 2. Evaluate the effects of the same three interventions on diagnoses of flu in the same patients.
Although the vaccination is the preferred method of influenza prevention, there are some occasions on which a postexposure prophylaxis (PEP) is required. Two neuraminidase inhibitors (NAIs) may be used in chemoprophylaxis in children: oral oseltamivir, and inhaled zanamivir. Both, oseltamivir and zanamivir, are effective in treatment and in prophylaxis of influenza, and the efficacy is calculated to reach 70-90%. Oseltamivir is used more frequently, since zanamivir is licensed in older children (5 years of age and above), and children under the age of 5 years are at higher risk of influenza complications. Oseltamivir use correlated in children with higher risk of vomiting, with no increased risk of other adverse events, including those observed in adult patients (nausea, renal events, and psychiatric effects). The PEP may be indicated by individual patient's characteristics (e.g. patients in high-risk group) or epidemiological reasons, i.e. prevention of institutional outbreaks.The one research that analyzed efficacy of 3-days PEP versus 7 or 10-days and showed overall efficacy of shorter oseltamivir prophylaxis to be high and comparable to that of longer regimens. The study included several pediatric patients and made the investigators perform such an analysis in pediatric population. In this randomized controlled trial, the investigators aimed to compare efficacy, safety, and costs of 3 versus 7-days prophylaxis with oral oseltamivir in children hospitalized. The hypothesis is that 3-days duration of PEP is not less effective than 7-days PEP, and patients might gain from lower number of adverse reactions related to drug administration.
Multicapillary Ion mobility spectrometry of nasal air aspirates shall be investigated as screening tool for the detection of Influenza and SARS-CoV-2- infection.
The main purpose of this study is: • to evaluate the efficacy and safety of MMH-407 in the treatment of influenza in outpatient adults.
This study series consists of four related studies and aims to explore and describe many important elements of alopecia areata over three key areas: (1) the current epidemiology of alopecia areata, (2) the prevalence and incidence of psychiatric co-morbidities in people with alopecia areata, (3) the prevalence and incidence of autoimmune and atopic conditions in people with alopecia areata, and (4) the incidence of common infections in people with alopecia areata.
Invasive pulmonary aspergillosis (IPA) has been reported in critically ill patients with influenza infection with a highly variable incidence between 1 to 21%. Studies investigating IPA in critically ill patients with influenza infection suffer limitations in their methods. It remains unknown whether patients with influenza are more at risk of IPA than other patients hospitalized in intensive care unit and whether patients with influenza who develop IPA have specific risk factors for this infection. Our study aims to determine the incidence of IPA in a large multicenter cohort and to identify risk factors for IPA in these patients.
The main aim of research is to determine of the prevalence of influenza virus and influenza vaccination coverage rate among hospital and GPs healthcare workers. Course of research: Participation in the study is voluntary and carried out after the consent of the examined person. The examination consists of: 1) completing the questionnaire and 2) taking the throat swab twice by the researcher. Two throat swab samples will be taken at the same time. Both samples will be used for virological examination to determine the presence of influenza virus material using non-invasive tests: one sample will be analyzed by a quick 'on-site' test - Flu SensDx kit, while the other sample will be transported to the laboratory, where the reverse transcriptase polymerase chain reaction (RT-PCR) - reference method - will be performed to confirm the presence of influenza genetic material. Swabs are planned to be collected during the 2019/2020 influenza epidemic season (January-March). In the last stage of the study, the results obtained from the survey questionnaire and the results of virological tests will be subject to statistical analysis and based on the data obtained, conclusions will be drawn from the study, indicating their practical application. The results obtained from this study will be used to develop a quality improvement program to control influenza virus infection, which will improve the safety of both patients and medical staff.
The primary objectives of the study were: - To demonstrate the non-inferiority of the immune response in terms of geometric mean titers (GMTs) and seroconversion rates of the SP Shz QIV compared with the SP Shz TIV containing the Victoria lineage strain (TIV1) and the SP Shz TIV containing the Yamagata lineage strain (TIV2) for each strain - To describe the safety profile of each dosage of SP Shz QIV, TIV1 or TIV2 The secondary objectives of the study were: - Group 1 (subjects 6-35 months): To demonstrate the superiority of the immune response of SP Shz QIV compared to TIV2 or TIV1 group after the last dose; demonstrate the superiority of the immune response of the 0.5 mL dose of SP Shz QIV compared to 0.25 mL dose of SP Shz QIV group after the last dose; describe the immune response after administration of the last dose of either SP Shz QIV or SP Shz TIV1 or SP Shz TIV2. - Groups 2 through 5 (subjects ≥ 3 years): To demonstrate the superiority of the immune response of SP Shz QIV compared to TIV2 or TIV1 group after a single dose; describe the immune response after each and every dose for all subjects ≥ 3 years of either SP Shz QIV or SP Shz TIV1 or SP Shz TIV2 - Group 2 (subjects 3 to 8 years), previously unvaccinated ,receiving SP Shz QIV: To describe the immune response after administration of each dose of SP Shz QIV, first dose and second dose of SP Shz QIV respectively - Group 5 (subjects ≥ 65 years only): To assess the compliance, in terms of immunogenicity, of SP Shz QIV with the requirements of the CHMP NfG CPMP/BWP/214/96 in subjects aged 65 years or older. - To describe the safety profile of SP Shz QIV 0.5 mL after each dose.
This Phase 2a clinical study is designed to evaluate the immunogenicity and the safety of one dose of OVX836 influenza vaccine administered IM, confirm the dose level and regimen, and expand immunogenicity and safety data to adults through age 65.
The investigators intend to observe the inflammatory marker procalcitonin (PCT) in comparison with patient variables on morbidity, mortality and antibiotic treatment. The overall aim is to observe if a low PCT value can have potential in reducing unessesary antibiotic use in seasonal influenza patients.
