Filter by:This is a multi-center, randomized, double-blind, placebo-controlled clinical trial to assess the efficacy and safety of GST-HG171/Ritonavir in the treatment of mild to moderate COVID-19.
The Grand Est region is one of the most affected regions in France during the first wave of the COVID-19 epidemic. A significant increase in the number of patients hospitalized for SARS-CoV 2 infection at the University Hospitals of Strasbourg (HUS) led to a sudden saturation of their capacities. Hospital workers appear to be a population at particular risk for this new infectious agent. The percentage of hospital workers who have been in contact with the virus or have contracted COVID-19 is unknown. The objective of this work is to determine the prevalence of SARS-CoV-2 positive serologies among hospital staff screened from June 22, 2020 to November 1, 2020 following a screening campaign offering serological testing to all volunteer HUS professionals.
This study is a randomized, double-blind, placebo-controlled Phase II clinical trial to evaluate the safety and immunogenicity of SCTV01E in population of different ages who have been vaccinated against COVID-19. A total of 750 participants ≥3 years old who have received the recommended dose and immunization procedure of domestically approved COVID-19 vaccines will be enrolled, including 250 participants ≥18 years old (group A), 250 participants aged 12-17 years old (group B), and 250 participants aged 3-11 years old (group C). The study will be carried out gradually according to the age of the participants from older to younger. Considering that SCTV01E in this study is the first clinical study in participants under 18 years old, 15 sentinel participants will be assigned to group B and 30 sentinel participants will be assigned to group C (including 15 aged 6-11 years old and 15 aged 3-5 years old). The Primary end points are 1. The incidence and severity of solicited adverse events on days 0-7 after inoculation with SCTV01E. 2. IgG total antibody concentrations (ELISA) against SARS-CoV-2 prototype strains and neutralizing antibodies titer (Live virus neutraliztion antibody test) against SARS-CoV-2 Omicron variant at 28 days post-vaccination.
It is aimed to reveal the treatment and prognostic values by evaluating the differences in hematological parameters and indices, especially in dead Covid-19 cases. Material Method: It is planned to retrospectively examine the hemogram parameters of 125 male, 44 female and 169 critical Covid-19 patients hospitalized between 01.03.2020 and 31.12.2021. Subjects were divided into 2 groups as deceased (77) and living (92) patients according to demographic data such as age and gender. Statistical evaluation: All analyzes were SPSS 25.0, Kolmogorov Smirnov test was used to determine distribution, median and interquartile range (Tukey's Hinges Percentile) were used to summarize variables. The differences between the Independent-Samples Mann Whitney U Test and the data of the patient groups and the optimal cut-off values, sensitivity and specificity values will be determined by ROC analysis. It will be considered statistically significant when the p value is below 0.05 (with the two-tailed test)
In this study we aim to evaluate the radiological and functional changes in post-acute covid-19 pulmonary fibrosis patients in relation to anti-inflammatory and/or antifibrotic drugs prescribed during and after covid-19 pneumonia.
The goal of this clinical trial is to learn about the effectiveness of supportive psychotherapy in post covid-19 syndrome patients. The main questions it aims to answer are: 1. What is the effect of supportive psychotherapy on psychological and somatic symptoms in post covid-19 syndrome patients? 2. What is the effect of supportive psychotherapy on the neutrophil lymphocyte ratio in post covid-19 syndrome patients? 3. What is the effect of supportive psychotherapy on heart rate variability in post covid-19 syndrome patients? Participants will be given supportive psychotherapy in the form of an online group for 3 times a week with a duration of psychotherapy ranging from 1 - 2 hours per session. Researchers will compare the supportive psychotherapy group to education group as control. The control group will be given education about Post Covid-19 syndrome in the form of an online group for 3 times a week with a duration of around 1 - 2 hours per session.
This study has two main objectives. First, the clinical characteristics and outcomes of hospitalized patients with symptomatic Covid-19 disease will be compared between persons with a history of past or current TB infection or disease and those, who have had no TB history. The possible impact of an HIV-coinfection will be also addressed in the planned investigations and analysis. Second, the long-term consequences and clinical outcomes of Covid-19 up to 12 months post-infection will be analysed in both groups (with and without TB history) with the main focus on cardio-pulmonary outcomes.
Randomized trial testing 6 forms of a communication summarizing the results of a recent study (about the effects of wearing glasses on reducing covid infection risk). The goal of the trial is to test the effect of different language options to describe uncertainty, and of including the margin of error around the main result.
Schools serve important community roles beyond academic education. In historically marginalized communities they are trusted providers for a range of support services for families in need. The tradeoff between these crucial benefits of in-person learning against the risk of SARS-CoV-2 transmission in school settings has been hotly debated throughout much of 2020 and 2021. The stakes are particularly high in historically marginalized communities which rely most heavily on school services, but have also been hit the hardest by COVID-19 primarily due to structural issues. The Safer at School Early Alert (SASEA) program was co-developed by the University of California, San Diego, the County of San Diego, and 15 partner schools serving socially vulnerable students in 5 school districts across San Diego County. SASEA utilizes daily wastewater and surface (floor) environmental monitoring to detect asymptomatic SARS-CoV-2 infections among students and staff on campus. Positive environmental signals are immediately followed by targeted responsive testing for a whole school (in the case of wastewater) or classroom (for a positive surface sample). In this project, we will develop the Safer at School Early Alert HUB (SASEA HUB), an online school environmental monitoring report dashboard with resources to address structural barriers to COVID-19 diagnostic testing in historically marginalized communities (Aim 1). We will also create a toolkit to allow any school to rapidly adapt the template to their specific setting. In Aims 2 and 3, we will use a randomized stepped wedge trial to compare SASEA (control) vs SASEA HUB (intervention) in 26 schools across 3 diverse school clusters in San Diego County. Our primary outcome (Aim 2) is higher rates of diagnostic testing in intervention schools. Our secondary outcome (Aim 3) is increased risk mitigation behaviors in school community members when environmental surveillance data suggests a potential case on campus. In Aim 4, we will use parent-child narrative interviews with 40 parent-student pairs to understand how children perceive COVID-19 risk at school, assess differences in perceptions of testing barriers between intervention and control sites, and better understand how children understand the process of environmental surveillance and responsive testing.
This is a Phase 2, randomized, double-blind, multicentre, placebo-controlled study in adults to assess the safety and efficacy of inhaled IBIO123, for post-exposure prophylaxis of COVID-19. This study aims to evaluate the efficacy and the safety of IBIO123 and the prophylaxis effect of IBIO123 in participants exposed to COVID-19 in the setting of current and uninterrupted household contacts.
