Since the first report of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant of concern (VOC) P.1 in Manaus, Brazil, a rapid spread of this lineage across the country has been observed. Recent studies indicate that this variant is associated with higher transmissibility; it is not known whether it is associated with clinical severity and higher mortality rates. This is a retrospective cohort study carried out at Hospital de Clínicas de Porto Alegre. Adult patients aged 18 years or more and 65 years or less who were admitted to the hospital due to symptomatic COVID-19 from June 2020 to May 2021 and had a reverse transcriptase-polymerase chain reaction (RT-PCR) cycle threshold value for either SARS-CoV-2 N1 or N2 target ≤ 25 were eligible to the study. Samples from 86 patients (43 from June 2020 to November 2020 and 43 from February 2021 to May 2021) were sequenced for further evaluation. These dates were defined since the emergence of P.1 lineage in late January. Clinical data regarding ventilatory support, date of onset of symptoms, laboratory findings and mortality were collected from each patient. This retrospective cohort aims to assess whether the number of days needed for supplementary oxygen either by noninvasive ventilation or high-flow nasal cannula from onset of symptoms differs among patients infected with the P.1 SARS-CoV-2 variant and those infected with other variants.
This study will evaluate the effectiveness of utilizing Osteopathic Manipulative Treatment (OMT) procedures as an addition to current mRNA COVID-19 vaccines in terms of enhancing the immune response of participants as assessed by looking for increased levels and duration of antibody titers.
The purpose of this study is to evaluate the efficacy and safety of XAV-19 drug in patients with moderate-to-severe COVID-19.
The key objective of the study is to measure the immune response against SARS-CoV-2 after different vaccinations in Health Care Workers (HCW) from 18 to 65 years old vaccinated once with Janssen vaccine. Determination of antibodies by a quantitative immunoglobulin G (IgG) assay (LIAISON SARS-CoV-2 TRIMERICS IgG essay) 28 days after second vaccination (booster) comparing, per protocol, the following three groups: 1. Janssen vaccine/- vs. Janssen vaccine/Janssen vaccine 2. Janssen vaccine/Janssen vaccine vs. Janssen vaccine/Pfizer vaccine 3. Janssen vaccine/Janssen vaccine vs. Janssen vaccine/Moderna vaccine
Background: People with COVID-19 have varying degrees of illness. It can range from no or mild symptoms to critical illness and death. Some people with COVID-19 have long-term effects regardless of the severity of their disease initially. Researchers want to learn more to see if they can better predict where a person may fall on the illness spectrum. Objective: To follow and record symptoms of COVID-19 to see how it progresses in people and why some people stay sick longer than others. Eligibility: People ages 18-65 who received a COVID-19 positive test result in the 72 hours before their enrollment in the study. Design: Participants will complete a 30-minute baseline survey. They will answer questions about themselves and their health. Participants will get a digital wristband and temperature sensor in the mail. They will get instructions on how to set up and wear the devices. They will download a mobile application on their phone. The app will collect data from the devices. Participants will wear the wristband and sensor every day for the first month. Then they will wear the devices for a total of 40 days over the next 5 months. On the days they wear the devices, they will answer a 2-question health survey via the app. Participants will answer a 20-minute online survey about their health every 30 days. If participants are hospitalized, a family member or close friend will be asked to complete a brief 7-minute online survey about their hospital stay and treatment. Participants will be sent alerts and reminders throughout the study. Participation will last for 6 months.
- To determine the impact of moderate exercise training on vitals (BP, HR) in different age categories of adult in COVID-19. - To determine the Impact of moderate exercise training on Peak VO2 in different age categories of adult in COVID-19 - To determine muscle discomfort due to physical training.
Comparison of the effects of CYT107 vs Placebo administered by intra-muscular route (IM) at 10μg/kg twice a week for three weeks on immune reconstitution of lymphopenic COVID-19 patients
This is a research study to evaluate the Sensitivity and Specificity of BIOZEK COVID-19 Antigen Rapid Test (Saliva) and BIOZEK COVID-19 Antigen Rapid Test (Nasopharyngeal Swab) on samples that are self-collected; and to perform analysis to compare results. In addition, to obtain RT-PCR test results, performed prior to enrollment, and compare all three results.
To estimate the pulmonary response microvascular thrombosis in critical patients due to SARS-Cov-2., at the Hospital General de México "Dr. Eduardo Liceaga", a 15 patients compassionate treatment study was authorized and approved by the ethics and research committee DI-222-2020. Because of the severity of the illness the legal representative sign informed consent in all the patients for performing in-situ thrombolysis with alteplase selectively by catheter in each main pulmonary artery, under fluoroscopic guidance and acquiring images with the iFlow software to assess immediate and post-procedure response.
