Filter by:The COVID-19 pandemic has had an outsized impact on individuals with underlying social and medical vulnerability, leading to increased rates of severe disease, hospitalization, and death in these groups. Participants with underlying immune compromise, such as those with multiple myeloma, represent one such group. The advent of vaccines against SARS-CoV-2 has significantly limited morbidity and mortality across all groups, but the effectiveness of vaccination in individuals who are less likely to mount sufficient antibody response is uncertain. For this reason, booster vaccines have been recommended for those with underlying immune compromise. However, several key gaps remain in our understanding of how to best protect these individuals. There is a dearth of real-world evidence about the effectiveness of vaccination and boosters in patients who are immunocompromised, and very little information specifically about the recently approved mRNA boosters. Additionally, rates of vaccination and booster uptake in the United States remain low. A rapid, decentralized method of ascertaining information related to booster vaccine response and adverse events related to vaccines and COVID-19 infection is critical not only to answer questions about the booster vaccines, but to develop an infrastructure for answering similar questions about future vaccines or other diseases.
During the pandemic of the new coronavirus infection COVID-19 in the world community, in the Russian Federation, in particular in the Samara region throughout the pandemic period from the end of 2019, when the first outbreak of a new coronavirus infection occurred in Wuhan (Hubei Province) in the People's Republic of China, the main focus on prevention (development of modern vaccines), diagnosis, treatment and further rehabilitation was done on the adult population. Children acted mainly as carriers of this infection and the manifestation of the disease usually occurred in most cases (not counting children with comorbid conditions) in a mild or latent form. At the moment, after 2 years, we can say that postcovid syndrome also occurs in children, regardless of the severity of the disease.
Investigators are evaluating whether an intervention consisting of box-fans with MERV 16 filters ("filtration fans") and recommendations for improving ventilation in the home can reduce secondary spread of Covid19 from an index case to susceptible contacts within the home.
Conduct a study of people who use drugs (PWUD) perceptions of and access to COVID-19 vaccines as well as reasons for vaccine hesitancy/barriers
As the COVID-19 pandemic continues and the number of individuals with previous infection rises, numbers of SARS-CoV-2 reinfection are increasing. The second Omicron wave in Shanghai, China caused by BA.5-sublineages led to a large fraction of reinfections among BA.2 primary infections. To better understand the SARS-CoV-2 reinfection rate and clinical severity of reinfections, the investigators conducted a multi-centre cohort study. The investigators hope to provide valuable clinical evidences for reinfections and offer guidance for future policy making.
Long COVID patients experience high symptom burden for many months after initial infection of the COVID-19 virus. This study will investigate a mobile intervention Merging Yoga and Self-Management Skills (MY-Skills Mobile) as a complementary therapy for fatigue, pain, mood and quality of life in long COVID patients at the UCHealth Center for Integrative Medicine. The study aim is to assess the feasibility and acceptability of MY-Skills Mobile and research procedures including planned assessments.
To evaluate the dynamics of IgG levels to the SARS-CoV-2 virus after a booster dose of Soberana Plus vaccine.
A prospective monitoring study for those individuals treated with Paxlovid
Aim of this prospective, observational, multi-centered, randomized study is to detect cardiovascular complications in patients after coronavirus infection. The study will include 100 patients who underwent confirmed by laboratory tests COVID-19 infection (polymerase chain reaction (PCR) testing, enzyme-linked immunosorbent assay (positive result at least 1 time)) 1-3 months ago with the degree of lung lesion more than 25%, who were admitted to the University Clinical Hospital No. 4 of I.M. Sechenov First Moscow State Medical University. The study consists of 4 periods: 1. Screening for up to 6 months. 2. Inclusion in the study, undergoing of identical laboratory and instrumental testing. 3. Re-examination of patients. After 6 months from the initial examination (9 months after discharge from the infectious diseases department), patients will be re-examined. 4 Determination of end points, statistical data processing. Estimated result of the study is to confirm or refute the hypothesis: 1. As a result of the analysis of ECG and pulse wave data and comparison with echocardiography data, identify cardiovascular complications of COVID-19 infection. 2. To determine the diagnostic significance of pulse wave parameters for assessing cardiovascular complications in patients with a history of COVID-19 infection (sensitivity, specificity, positive and negative predictive value). 3. Identify correlations between pulse wave parameters and biochemical markers of endothelial dysfunction (endothelin-1). 4. As a result of the analysis of exhaled air by the proton mass spectrometry, to identify markers of cardiovascular complications in patients after COVID-19 infection. 5. As a result of a cardiorespiratory stress test, determine the respiratory and cardiovascular causes of dyspnea, exercise tolerance of patients after infection with COVID-19.
This study is a platform protocol designed to be flexible so that it is suitable for a wide range of settings within health care systems and in community settings where it can be integrated into COVID-19 programs and subsequent treatment plans. This protocol is a prospective, multi-center, multi-arm, double-blind, randomized, controlled platform trial with different interventions organized as appendices to the protocol. Each appendix (or sub-study) evaluates potential mechanisms of action, efficacy, and safety of antivirals and other therapeutics in individuals with PASC, according to the platform protocol objectives. The hypothesis is that persistent viral infection, viral reactivation, and/or overactive/chronic immune response and inflammation are underlying contributors to PASC and that antiviral and other applicable therapies may result in viral clearance or decreased inflammation and improvement in PASC symptoms.
