Filter by:This clinical study aims to investigate the safety and efficacy of nebulized inhalation of extracellular vesicles derived from mesenchymal stem cells combined with standard therapy for COVID-19-infected individuals. The primary objective is to determine whether nebulized MSC-secreted extracellular vesicles may be a feasible approach to alleviate COVID-19-induced lung injuries and promote recovery. Participants will be allocated to receive either nebulized MSC-secreted extracellular vesicles twice a day (BID) for 5 days as the test group or nebulized saline solution twice a day for 5 days as the control group. Researchers will compare the test and control groups to evaluate the safety and efficacy of extracellular vesicles in combination with standard therapy.
Rationale: The highest rates of coronavirus disease (i.e., COVID-19) vaccine hesitancy in the US are among young adults (YAs) aged 18-25. Our preliminary studies show that social norms - perceptions of peers' vaccination attitudes/behaviors - are most strongly related to YAs' vaccine intentions/uptake. Most YAs underestimate the perceived importance of vaccination and their peers' intentions to be vaccinated. The proposed research will develop and test an intervention to correct misperceived norms for vaccination hesitancy and uptake. Methodology: Rapid prototyping with 20 unvaccinated YAs will help refine the content and design of the online intervention. Then, a diverse national sample (N=600) of unvaccinated YAs will be randomized to treatment or an attention-matched control. The treatment condition will receive personalized normative feedback (PNF) designed to correct normative misperceptions for vaccine hesitancy and uptake. Normative feedback will be derived from the US Census Bureau's Household Pulse Survey. Follow-up surveys will be administered at 1, 2, 3, and 6 months to assess key outcomes including vaccine uptake, intentions, and reasons for vaccine hesitancy. Aims and Data Analysis: - Aim 1: Develop and refine a PNF intervention for vaccine hesitancy/uptake with user feedback from YAs. Rapid analysis of qualitative data will involve looking for themes in responses. Changes will be made iteratively to refine intervention content, design, and delivery. - Aim 2: Evaluate intervention efficacy for increasing vaccine uptake and reducing time to first vaccine dose, relative to control, over the following year. - Aim 3: Examine mediators (changes in perceived norms) and moderators (intellectual humility, identification with other people and young adults) of intervention efficacy. A longitudinal moderated mediation model will be examined. Impact: Findings will clarify the causal role of psychological determinants of vaccine hesitancy (social norms, intellectual humility, group identification). If preliminary intervention efficacy is supported, this intervention could be a low-cost, and easily disseminated strategy to promote YAs' vaccine uptake and contribute to public health efforts to address the COVID-19 pandemic.
The goal of this clinical trial is to evaluate the safety, tolerability, and efficacy of NP-101 in treating high-risk participants who have tested positive for Covid-19. The main question[s] it aims to answer are: - To evaluate the safety of NP-101, as well as establish the maximum tolerated dose in high risk Covid-19 positive patients. Participants will [describe the main tasks participants will be asked to do, treatments they'll be given and use bullets if it is more than 2 items]. If there is a comparison group: Researchers will compare [insert groups] to see if [insert effects].
The aim of this study is to evaluate the effectiveness and safety of MIR 19 ® in preventing development of moderate and/or severe course of the disease in mild COVID-19 outpatients. Primary endpoint: The proportion of patients with the development of moderate or severe COVID-19 disease (in accordance with the criteria specified in the Interim Guidelines "Prevention, diagnosis and treatment of new coronavirus infection (COVID-19)" by the Ministry of Health of the Russian Federation, version 14 of 27.12.2021 or current at the time of the study) by the 28th day of observation.
The goal of this clinical trial is to learn about the safety and efficacy of Sesderma LACTYFERRIN™ Forte and Sesderma ZINC Defense™ in non-hospitalized patients with COVID-19. The main question is: Is there a reduction in the signs and symptoms of COVID-19 from baseline to end of treatment? Participants will complete the following activities. - Screening and first day of treatment - Treatment that will be administered for up to 10 days, two treatment evaluation visits will be completed - After treatment completion. Two visits are scheduled, one 28 days after the last dose and the other 60 days after the last dose. Researchers will compare Treatment Group (Sesderma LACTYFERRIN™ Forte and Sesderma ZINC Defense™ + Standard of care (SOC)) with the Control group (Placebo +SOC) to see if there is Reduction in the signs and symptoms of COVID-19 at the end of treatment
The Basel Long COVID Cohort Study (BALCoS) is a registry-based cohort study that focuses on the patients' present health status, symptoms, the course of these symptoms, and potential mechanisms involved. The project aims to investigate proposed mechanisms behind Post COVID-19 condition (PCC), including a) autoimmunity, b) chronic inflammation, c) genetics, d) coagulation disorders, and e) psychosocial factors. Patients in the cohort can also join the Digital Long COVID Study (DiLCoS). This substudy evaluates whether doing exercises delivered via a smartphone app (referred as digital intervention) can help with PCC. The digital intervention is a 12-week program that includes different kinds of exercises like breathing exercises, relaxation techniques, and tips on managing fatigue and other symptoms. It also teaches patients how to monitor their activities and energy levels, and provides psychological exercises to cope with negative thoughts and pain. Patients in the cohort complete a set of assessments that include the collection of sociodemographic and clinical data, biomarkers, neurocognitive testing, psychometric questionnaires, and measures of physical performance, and provide consent that their data from routine clinical care can be used for the study.
To explore the relationship between SARS-CoV-2 infection in different time before operation and postoperative main complications (mortality, main pulmonary and cardiovascular complications) 30 days after operation; To determine the best timing of surgery after SARS-CoV-2 infection.
This study investigates healthcare workers' attitudes towards co-administering COVID-19 and seasonal influenza vaccines, a method supported globally for its efficiency and potential to lessen healthcare burdens. It explores various factors affecting workers' willingness to accept or decline this approach, ranging from demographic to logistical aspects, and examines the link between vaccine hesitancy and co-administration acceptance, aiming to identify and address hesitancy towards both vaccines
