Active clinical trials for "COVID-19"

This is a multicenter, international, randomized, active-controlled platform study with each sub-study designed to randomize subjects to receive a single injection with UB-612 or a comparator COVID-19 vaccine in 1:1 ratio.

In the current COVID-19 pandemic, many patients have an acute respiratory distress syndrome (ARDS). Among mechanisms related to COVID-19 acute respiratory distress syndrome, cytokine storm and secretion of IL-6 play a central role. ARDS management involves intubation for protective mechanical ventilation, deep sedation and curarisation. During intensive care unit (ICU) hospitalization, improvement of hematosis induces a switch from a controlled ventilation mode to a withdrawal ventilation mode, such as Spontaneous Ventilation with Pressure Support (SP-PS) or Adaptative Support Ventilation (ASV). This step is essential prior to considering complete weaning from controlled ventilation and sometimes ends with a failure. In this case, deterioration of hematosis and/or ventilatory mechanics is observed. At the same time as withdrawal failure, the investigators observed biological inflammatory rebound in some patients. Therefore, influence of inflammatory biological parameters, including IL-6, on withdrawal failure, needs to be investigated. To this end, the investigators decide to dose different inflammatory markers - such as IL6, C-Reactive Protein (CRP), Procalcitonin (PCT) - in patients with acute respiratory distress syndrome due to COVID-19, during standard of care. Indeed, in patients with acute respiratory distress syndrome not due to COVID-19, the increase in IL6 is a negative prognosis during medical first aid but also when the mechanical ventilation is withdrawn. In addition, IL6 rise is associated with poor prognosis for patients with COVID-19 and longer stays in intensive care.

It is a Single Arm, Open Label Clinical Study to Evaluate the Immunogenicity and Safety of Sequential Immunization of V-01-351/V-01D Bivalence Vaccine in Healthy Adults Aged 18 Years and Older After the Vaccination of 2 Doses of Inactivated Vaccines. A total of 20 participants were enrolled.

The aim of the study is to assess the incidence of potentially inappropriate medication (PIM) administration, polypharmacy, and potential drug-drug-interactions (PDDIs) in cardiovascular patients enrolled in the reimbursement program in the time of coronavirus disease (COVID-19) pandemic. Medical information system (MIS) "BARS" will be used for inclusion and retrieval of relevant data of cardiovascular patients aged 75 years and older enrolled in the reimbursement programs in the Tomsk Region. The incidence rates of PIM prescriptions will be assessed. Potentially inappropriate medications will be defined according to 2015 Beers criteria. Polypharmacy will be defined as being administered five or more medications at the same time. PDDIs will be checked with Medscape Drug Interaction Checker and rated as 'Contraindicated', 'Serious', and 'Requiring Monitoring'. Combined analysis of retrospective and prospective occurrences of study parameters will be performed. PIM-BARS will evaluate the incidence rates and patterns of PIM prescriptions, polypharmacy, and PDDIs in elderly cardiovascular patients enrolled in the reimbursement program in the time of COVID-19 pandemic.

A Clinical Study to Evaluate the Immunogenicity and Safety of Sequential Immunization of Recombinant SARS-CoV-2 Fusion Protein Vaccine (V-01) Against COVID-19 in Healthy Adults Aged 18 Years and Older After the Vaccination of 2 Doses of Inactivated Vaccines

The purpose of this study is to evaluate a unique culturally-tailored intervention aimed at increasing healthy eating and physical activity in Ultra-Orthodox Jewish women during the COVID-19 pandemic. Utilizing a pre-post study design, this intervention is based on the CDC's Diabetes Prevention Program (DPP) and integrates low-tech media, partner learning, group support, and practical workbook content.

Recent research evidence shows that levels of antibodies acquierd post vacunation against SARS-Cov-2 decrease over time as well as the efficacy to control the infection, additionally in a multicenter study carried out in 2020 were evidenced differences in the time it took to decrease the antibodies according to the type of vaccine, defined as mRNA or other types of vaccine. In this study , the variation of the SARS-Cov-2 antibody levels in patients from Valle de Aburrá will be correlated according to the COVID-19 vaccine received.

The study is aimed at assessing the role of the activity of high-risk markers of thrombotic events (MCP-1, MIP1α, IP-10, phosphatedylserine, calreticulin) on the development of thrombotic complications in patients with COVID -19.

The impact of the Covid-19 pandemic on medical education is real but little known. ENT interns were directly affected by the management of Covid-19 patients (performing surgical tracheostomies), many conferences and trainings were cancelled, their usual hospital activity deeply reshuffled. Although each student has a personal story of the impact of Covid-19 on their training, there is no doubt that the effects of Covid-19 are felt at scale. This study aims to investigate the effect of the pandemic on the medical and surgical training of ENT and Cervico-Facial Surgery interns in France from November 2019 to May 2021 (Auvergne-Rhône-Alpes, Grand Est, Ile de France, Nouvelle Aquitaine and Provence-Alpes-Côte d'Azur areas). A questionnaire will be sent by mail to ENT interns in France to assess the impact of Covid-19 on the training of ENT interns in France.

Background:The impact of the emergence of SARS-CoV-2 variants on the severity and clinical outcomes of COVID-19 is controversial. Whether virological characteristics including the mutational patterns of the different viral proteins (e.g., Spike, NSP proteins, ORF6) could be associated with a different immune response and subsequent severity of the disease is unknown. ln the next coming months, new variants carrying the same or new mutational patterns will continue to emerge. Monitoring their dynamics over time and their impact on disease severity is required for refining national and international disease control policies. Main objective: To unravel the relationships between specific viral mutations/mutational patterns and the clinical outcomes of COVID-19 in patients hospitalized in intensive care units (ICUs) for acute respiratory failure following severe SARS-CoV-2 infection. Design of the study Prospective multicentre observational cohort study Schedule for the study: Inclusion period: 24 months; Participation period: 28 days ; Total duration : 24 months + 28 days;
