Filter by:The nature of the planned study: The topic is of an applied nature and is aimed at improving the results of comprehensive treatment of patients with COVID-19, the course of whose disease was complicated by thrombotic or hemorrhagic catastrophes. It is planned to analyze the results of treatment of this category of patients based on the work of several centers that provided surgical care to patients with COVID-19 during the pandemic (8 cities). As a result of the analysis, it is planned to develop algorithms for the prevention and treatment of thrombotic and hemorrhagic complications in patients with COVID-19. The proposed study will be multicenter, cohort, retrospective. The purpose of the study: Improvement of treatment results in COVID-19 patients with thrombotic or hemorrhagic complications Scientific novelty: For the first time, as a result of a multicenter study, it is expected to identify the most effective approach to the treatment and prevention of thrombotic and hemorrhagic complications in patients with COVID-19. For the first time, it is planned to develop and put into practice algorithms for the application of the most effective methods of treatment and prevention of thrombohemorrhagic complications of COVID-19.
Evaluation of the Efficacy and Safety of Molnupiravir Treatment in Mild/Moderate Covid-19 Patients. Turkey Cohort, Prospective, Observational, Comparative Study In the antiviral treatment of COVID-19, molnupiravir, an RdRp (RNA-dependent RNA polymerase) inhibitor, was the first agent shown to reduce death and hospitalization in a reliable/adequate phase-3 clinical trial. For this reason, molnupiravir has been approved for emergency use in many countries, including Turkey, as it is still an unmet need in the treatment of COVID-19. However, it is not yet known which factors related to the patient or the disease are important for this drug to be effective. In addition, since this is the first time it will be widely used, rare or long-term adverse effects have not been identified. Since molnupiravirin is known to exert antiviral activity by inducing mutations in the virus, there are some hypotheses that this effect may lead to the emergence of new and more dangerous variants.
This cross-over study will assess a no added sugar diet, a restricted daily eating window, and one or two full day water fasts to determine if there is an effect on self-reported symptoms of Long Covid (PASC).
The primary purpose of this study is to learn about how well different versions of the Pfizer-BioNTech COVID-19 vaccine (called BNT162b2) work at preventing death, severe COVID-19 that requires a trip to the hospital, and overall use of healthcare resources, such as needing to go the doctor or urgent care due to illness. Pfizer is not enrolling any participants for this study. Instead, existing data from different health data sources will be used to help answer the scientific questions Pfizer is interested in learning more about.
the aim of this study will be to investigate the effect of aerobic exercises vs incentive spirometer device on post-covid patients with residual lung diseases.
The research objective is to assess the safety and potential efficacy of spleen ultrasound stimulation as an intervention for Long COVID in a pilot study. Specific Aims include: - Measure Long COVID disease activity before, during and after an 8-week course of spleen-directed daily ultrasound stimulation. - Measure molecular correlates of Long COVID disease activity before, during and after an 8-week course of spleen-directed daily ultrasound stimulation. - Track adverse events throughout the study to assess safety of the ultrasound intervention.
The main goal of this study is to characterize presentation, clinical course, and long-term outcomes of myocarditis temporally associated with administration of mRNA-1273 (SPIKEVAX) COVID-19 vaccine.
This is a phase IIb/III, double-blind, randomised, active-controlled, multi-centre, non-inferiority clinical trial that aims to determine safety, tolerability and immunogenicity of a booster vaccination with a recombinant protein receptor binding domain (RBD) fusion homodimer of XBB.1.16 adapted candidate against SARS-CoV-2 developed by HIPRA (PHH-1V81).
The purpose of this study is to understand the safety and effects of a combined influenza and COVID-19 vaccine. This combined vaccine is compared to separate vaccines for the protection against influenza and SARS-CoV-2. Influenza and COVID-19 are diseases that can spread easily from one person to another and cause body aches, fever, cough, and other symptoms. Giving both influenza and COVID-19 vaccines together against influenza and SARS-CoV-2 could provide great benefits to both patients and caregivers in terms of simple and easy care. Around 8550 participants will be assigned into 1 of 8 vaccination groups (Group A, B, C, D, E, F, G or H) by chance. Cohort 1: Approximately 450 participants will be assigned by chance to one of the following: - Group A:Influenza and COVID-19 combination A vaccine, given at the same time in one arm and placebo (an injection consisting of just salt water and no medicines in it) in the opposite arm. - Group B: COVID-19 vaccine, given at the same time to one arm and licensed influenza vaccine in the opposite arm. Cohort 2: Approximately 4500 participants will be assigned by chance to one of the following: - Group C: Influenza and COVID-19 combination B vaccine, given at the same time in one arm and placebo in the opposite arm. - Group D: COVID-19 vaccine, given at the same time in one arm and licenced influenza vaccine in the opposite arm. Cohort 3: Approximately 3600 participants will be assigned by chance to one of the following: - Group E: Influenza and COVID-19 combination B vaccine. - Group F: COVID-19 vaccine. - Group G: Licenced influenza vaccine. - Group H: Investigational influenza vaccine. All participants in cohort 1 and cohort 2 will receive 2 injections and participants in cohort 3 will receive 1 injection as per their assigned study group at Visit 1. The participants will be followed for about 6 months. During this time, researchers will assess safety and the body's reaction to the vaccination over approximately 6 months. This will help understand if the study medicine is safe.
The goal of this observational study is to retrospectively analyze left atrial function in mild to moderate COVID-19-recovered patients. The main questions it aims to answer are: - Whether left atrial function is involved in patients with mild to moderate COVID-19 after recovery. - What are the factors that may be associated with persistent heart-related symptoms (including chest pain, chest tightness, palpitations, shortness of breath, or postural tachycardia) in patients with mild to moderate COVID-19 ? Participants will undergo transthoracic echocardiography to obtain conventional ultrasound parameters, two-dimensional strain parameters will been obtained through software post-processing, and general clinical data and laboratory test results will been obtained.
