This study was carried out to determine the fear of Covid-19 and the compliance with protective measures of students who continue their education face-to-face during the covid-19 pandemic process.
The primary objective of this study is to determine the vaccine effectiveness of 2 doses of Pfizer-BioNTech BNT162b2 vaccine against COVID-19-associated hospitalization. There will be a large retrospective database study using two parallel study designs: a test-negative case-control design and a retrospective cohort design. Exploratory analyses of VE estimates by strain type will be conducted.
This is a multicentre observational study with the aim of evaluating the antibody and cellular response after vaccination for SARS-CoV-2 with Pfizer-BioNTech or Moderna vaccines in frail subjects with impaired immuno-competence, due to their underlying diseases or ongoing therapies.
Aim:There is still not enough data to determine methylprednisolone treatment timing, dosage, duration of use and indication in Covid 19 pneumonia. The aim of this study is to examine the relationship between drug dose and hospitalisation time and mortality rates in patients with pre-diagnosis of severe covid pneumonia and systemic methylprednisolone. Materials and Methods: The demographic data, symptom durations, thorax CT findings, methylprednisolone dose and duration of treatment, hospitalisation times, intensive care hospitalizations of the patients who were initiated and hospitalized in the emergency department will be retrospectively recorded. Finally, the fate of the patients (such as discharge, referral, death) will be recorded.Statistical analysis will be conducted using the Statistical Package for Social Sciences (SPSS) (IBM Corp. Released 2015. IBM SPSS Statistics for Windows, Version 21.0. Armonk, NY: IBM Corp.) program.
Covid-19 disease is one of the most important health system challenges which is the result of the recent SARS CoV-2 virus outbreak. So far, despite the use of different types of pharmaceuticals, none has been served as a curative treatment and research is continued to find one or more effective drugs; either palliative or curative ones. One of the most important clinical problems in Covid-19 patients is lung involvement, which may causes significant sequels; leading to a main part of morbidity and/or mortality. Surfactant is one of the drugs that can have valuable effects on the lungs, both by reducing the alveolar surface tension and by exerting immunomodulatory effects. In a previous study by the same team, favorable effects were seen in intubated patients; however, the aim of this study was to evaluate the effect of exogenous nebulized surfactant in the pre-intubation stages of the disease.
The purpose of the study is to compare the efficacy of anti-COVID-19 immune globulin (human) 20% (C19-IG 20%) (2 doses) versus placebo with regard to the percentage of asymptomatic participants who remain asymptomatic, i.e., who do not develop symptomatic coronavirus disease 2019 (COVID-19) through Day 14 as per the protocol defined criteria.
Approximately 28,000 subjects will be enrolled in this trial. Eligible subjects will be stratified by age (<60 years of age and ≥60 years of age, the proportion of elderly people ≥60 years old is planned to be ≥25%) and randomly assigned into the study group and the control group at a ratio of 1:1 (14,000 in each group) to be intramuscularly administered with the investigational vaccine or placebo in a 2-dose regimen at an interval of 28 days. The experimental vaccines will be cross-vaccinated after available data of the investigational vaccine show that expected efficacy and good safety have been achieved (i.e., subjects in the study group will be vaccinated with placebo and those in the control group will be vaccinated with the investigational vaccine in the same schedule as stated above ). After the completion of the second dose for crossover vaccination, subjects will be followed up for 12 months for safety observation. An immunogenicity subgroup (n≥3000) and a reactogenicity subgroup (n≥6000) will also be included in this trial to evaluate the humoral immunity induced by the investigational vaccine and the solicited adverse events observed within 7 days post immunization. All enrolled subjects will be followed up for the evaluation of protective efficacy as well, which will be primarily characterized by the incidence rate (person-year) of COVID-19 cases collected from 14 days after complete series. Adverse events will be collected over 0-28 days after each vaccination and serious adverse events will be collected from Dose 1 through 12 months post complete series.
Adaptive platform trial to enable the evaluation of investigational products for early treatment and post-exposure prophylaxis of COVID-19.
This is the first study performed within the ESPERES cohort, related to prevention against COVID-19, in particular vaccination against COVID-19 and more broadly on the COVID-19 pandemic. ESPERES is a national prospective e-cohort study providing a resource for collecting information on healthcare workers (HCWs) currently working in France. The overall goal of ESPERES is to develop the infrastructure necessary to create and engage a community of HCWs who may be eligible for participation in future research studies. ESPERES is set up to answer research questions, in the field of prevention for HCWs, prevention for their own health, that of their relatives, their colleagues, and users of the hospital. These research questions will be carried out in the context of specific subsequent studies.
The objective of this study is to compare the effects of twice-a-day 15-minute sessions of inpatient physical therapy (PT) to the standard daily 30 minute sessions. The patient outcomes that will be evaluated will be length of stay, change in functional status, and disposition (home/acute rehab vs. subacute/LTAC/death) in patients admitted with COVID-19.
