Filter by:AIM 1. Characterize cardiovascular phenotypes of long COVID by cardiopulmonary, meta-bolic, and cardiac mechanical/physiological responses to exercise and microvascular vasomotor function. AIM 2. Identify intercellular signaling between immune cells and cardiac cells associated with microvascular phenotypes of long COVID.
The main purpose of this study is to understand: - the symptoms of COVID-19 or influenza - health-related outcomes of people with COVID-19 or influenza - the effects of vaccines in people with COVID-19 or influenza. This study will take in participants who are: - 18 years or older - reported to have symptoms with lab tests that have confirmed illness. The lab tests can be tested at any of Walgreens pharmacy COVID-19 or influenza test sites. The study will collect vaccine history information from participants who are ready to take part in the study. Participant will be emailed a form with questions about their health related to COVID-19 or influenza during twelve follow-ups over a 6-month period.
The aim of the trial is to assess the safety of using simplified personal protective equipment (PPE) for vaccinated or COVID-19 convalescent healthcare workers working in COVID-19 ICU or COVID-19 wards. The trial is designed as a prospective randomiyed observational trial with volunteer medical staff working in COVID-19 departments aiming to show non-inferiority of simplified PPE vs standard COVID-19 PPE.
The purposes of our study are to: 1) determine the incidence of paradoxical response to chest wall loading in mechanically ventilated patients; 2) identify sub-populations in which it is most likely to occur (e.g., severe ARDS); and 3) standard the bedside procedure for demonstrating this physiology.
The expanded access program for investigational convalescent plasma (CP) is being utilized nationwide despite its unproven benefit and optimal timing of transfusion. The optimal administration of CP during a viral pandemic must consider the supply of the product, ideal patient selection, and appropriate timing in order to produce maximum benefit with a scarce resource [2]. Currently, the FDA suggested guidelines for use include "severe", "critical" or at risk for critical disease. The optimal administration of CP with anti-SARS-CoV-2 antibodies is theoretically early in the course of the illness [1], before multiorgan failure or a maladaptive immune response, like seen in the cytokine release syndrome, occurs. Our open-label trial will randomize COVID-19+ patients admitted to the hospital who are at high risk for severe disease to receive 1 dose CP ordered within 48 hours of admission plus standard of care vs. standard of care. The primary clinical endpoint will be time to clinical improvement within 28 days after randomization (based on the ordinal scale as specified below). The purpose of this trial will be to obtain data which can be further utilized in future clinical trials and help clinicians understand the effectiveness of CP.
The COVID-19 pandemic severely impacted the medical system both directly but also through incomplete recovery from the virus in the form of post-acute sequelae of COVID-19 (PASC). PASC affects at least 9.6 million individuals as of May 2022 and continues to affect many more. PASC is a multisystem disorder often presenting with mental fog, dyspnea on exertion, and fatigue among other symptoms. The etiology of PASC is uncertain but theories include direct cytotoxicity, dysregulated immune responses, endotheliitis associated with microthrombi, eNOS uncoupling, and myocardial fibrosis with impaired ventricular compliance. To date, there are no established treatments. Exercise has the potential as a therapeutic option to improve VO2peak and improve each of the aforementioned underlying etiologies. The investigators plan to examine the effect of High-Intensity Interval Training (HIIT) and Moderate intensity exercise training (MOD) on the symptoms and exercise tolerance of patients with PASC. The investigators approach will consist of a randomized, blinded, 2-arm, parallel-group design. Enrolled subjects will be randomly assigned to one of two groups in a 1:1 allocation ratio. All groups will undergo a 4-week intervention of 3 days of HIIT per week and 2 days of MOD per week or control of light stretching and controlled breathing. Subjects will be assessed before and after the 4-week intervention to examine the extent to which 4 weeks of the HIIT and MOD combination improves VO2peak and left ventricular diastolic function, global longitudinal strain (GLS), and global circumferential strain (GCS). Further, the investigators will explore changes in markers such as heart rate, heart rhythm, blood pressure, quality of life, exercise tolerance, and PASC symptoms as well as blood/serum markers.
The purpose of this study is to collect information on the: - general information of a group of people such as their age, sex, and other facts. - clinical information of the patients such as any other illness before having COVID 19. In adult patients with COVID-19 who have been prescribed nirmatrelvir and ritonavir treatment. This study will be conducted in Morocco. The study will capture information of the adult COVID-19 outpatients and inpatients who have been prescribed nirmatrelvir, ritonavir treatment. The inpatients will be admitted in the hospital for other reasons than COVID-19. This study will have about 150 patients. The study will involve collection of patient information from medical records. The information collected can be either from papers or from computers. The study will include patient information of those who: - are confirmed to have COVID-19 infection during the study period from 01 June 2022 to 30 June 2023. - are 18 years of age or older. - are prescribed Nirmatrelvir and ritonavir. This study will help to inform decision-making on use of Paxlovid at the national level.
In this multi-center phase II clinical trial, adults in stable health conditions will be vaccinated twice with either a low dose or high dose of the candidate vaccine MVA-SARS-2-S, or placebo. The aim of the study is to assess the safety and immunogenicity of the candidate vaccine.
The purpose of this study is to assess the immunogenicity and safety of SCB-2023 trivalent vaccine compared to the prototype SCB-2019 monovalent vaccine in participants previously vaccinated with 3 doses of inactivated COVID-19 vaccine ≥6 months prior to enrollment.
