Filter by:Despite COVID-19 pandemic having started more than one year ago, there are still limited treatment options for these patients, and over 145 million cases and 3 millions deaths have ensued worldwide. Fortunately, SARSCoV2 vaccines have been developed at an unprecedented pace. While the vaccination programs are still ongoing, early reports on efficacy are mainly centered on healthy population. In Chile most people have received the inactivated Coronavac vaccine. Data on the immune response after vaccination in immunocompromised patients is lacking. Therefore, this study aims to evaluate the immune response after Coronavac vaccine in 5 cohorts of immunocompromised patients and healthy controls. We will include patients with cancer, HIV, solid organ transplant and patients receiving immunomodulatory agents for rheumatic diseases.
Study of the safety and immunogenicity of 20vPnC and a booster dose of BNT162b2 administered at the same visit or each vaccine given alone
Patients requiring admission to the hospital due to a moderate and severe COVID-19 infection may differ in their ability to respond to viral infection and to eliminate viral load. Several comorbidities and interventions like antivirotic or antiinflammatory treatment may also modify expected patients response and decrease of viral load. In this observational study, evolution of selected inflammatory markers, indicators of severity of infection and patient characteristics will be followed and recorded in hospitalized patients with COVID-19.
Background: Respiratory and cardiovascular complications have emerged as dominant threats during and following coronavirus disease (COVID19) infection. Severe COVID19 infection is categorized as acute respiratory dysfunction leading to hospitalization, where as a mild infection is identified as symptoms of dyspnea, muscle pains, migraines, palpitations and/or fatigue persisting for several weeks. Recovery from COVID19 infection is poorly characterized, but symptoms appear to gradually decline over a four to eight-week period. Unfortunately, recovery from severe infection is similar to symptoms experienced with mild infection making it rather difficult to provide a physiological definition of recovery for mild infection sufferers. Considering that 81% of COVID19 infections are found to be mild, approximately 4.5 million Americans may be vulnerable to inadequate cardiovascular recovery that exacerbates reductions in physical capacity and quality of life. Combined respiratory muscle and exercise training enhance cardiorespiratory function, maximize return to activities of daily living, and reduces hospitalization times in heart failure, sepsis and severe acute respiratory syndrome. However, it is unclear if these interventions will also enhance cardiorespiratory and cerebrovascular COVID19 recovery. Therefore, utilizing cardiorespiratory and cerebrovascular rehabilitation techniques we propose these specific research aims and hypotheses to investigate the following: 1. Does individualized cardiac exercise rehabilitation enhance cardiorespiratory & cerebrovascular recovery? Hypotheses: 1. Individualized exercise therapy designed to increase fitness will enhance cardiorespiratory function at rest, as well as during and following exercise in individuals recovering from COVID19. 2. Cerebrovascular function at rest, as well as during and following exercise will be enhanced following individualized exercise therapy in individuals recovering from COVID19 infection. 3. The magnitude of post-training cardiorespiratory enhancements will be associated with cerebrovascular adaptations in individuals recovering from COVID19 infection. 2. Does combining inspiratory muscle and cardiac exercise rehabilitation provide additive cardiorespiratory and cerebrovascular COVID19 recovery benefits? Hypotheses: 1. The addition of inspiratory muscle training to individualized exercise therapy will enhance cardiorespiratory adaptation in individuals recovering from COVID19 infection. 2. Improved cardiorespiratory function associated with inspiratory muscle training and exercise therapy will add further recovery advantage to cerebrovascular function in individuals recovering from COVID19 infection. Study Design Scientific Plan: This project aims to collect pre- and post-intervention cardiorespiratory and cerebrovascular measures in individuals 1- 4 weeks after recovering from COVID19 infection (n=40; 20 ♀ & 20♂). Each participant will be randomized to either Supervised Exercise Training (EXT; n=20) or combined inspiratory muscle and exercise testing (IMET; n=20) interventions. Randomization will match for age and sex, and will attempt balanced matching of any cardiovascular (hypertension, atherosclerosis), respiratory (chronic obstructive pulmonary disease, asthma), and metabolic (diabetes, metabolic syndrome) comorbidities between interventions. Prior to beginning EXT or IMET, participants will complete baseline fitness, respiratory muscle testing, cardiovascular, and cerebrovascular measures to DEXA body composition scan (dual energy X-ray absorptiometry, DEXA) determine the initial intensity and post-intervention effectiveness, respectively. Following baseline testing, participants will complete a 6-week EXT or IMET intervention. EXT: Supervised EXT will include a progressive individualized program that combines aerobic and resistance protocols. Volume progression will begin with 3-days of supervised training sessions/wk and will increase by 1 session/wk to a maximum of 5-days/wk. Each EXT session will include 30 minutes of aerobic training (15 minutes cycling; 15 minutes treadmill walking/running/elliptical) and 30 minutes of resistance training (specifics below). Considering individual fatigue will be a concern, therefore similar to exercise training standards in COPD, the duration of rest periods may be extended (~1-3 min) as needed, however all exercise durations will be completed within a 1.5-hour time slot. IMET: All IMET sessions will be performed similar to EXT, with the exception of having 3-sessions of at home IMT training. On these days, all training will be spread out over a 2-hour session with periods of IMT training occurring at the beginning, middle and end of the session.
There are relevant questions that need to be answered about the effectiveness and safety of COVID-19 vaccines. The objective of this observational study is to follow up the clinical outcomes after vaccination in all the headquarters of the National University of Colombia. It is a project that is considered institutional importance and is part of the actions that the National University of Colombia has proposed to the national government to accompany the national vaccination program. The proposed follow-up includes the sociodemographic, cultural, clinical and pharmacological characterization of the vaccinated population, including the report of adverse events occurring after the vaccination process, the behavior of the population after the administration of the vaccine, monitoring serological outcomes, identification of medication errors and therapeutic failure. Three stages are proposed in which the population affiliated to UNISALUD is gradually included, then the beneficiaries and later the student community and their families. The scope of the attached protocol includes Stage I, which corresponds to teachers and administrative staff (active and retired) linked to UNISALUD.
This Phase III study is a global multicenter, randomized, double-blind, placebo-controlled clinical trial to evaluate the efficacy, safety, and immunogenicity of the recombinant COVID-19 vaccine (Sf9 cells) in 40,000 participants aged 18 years and older who do not have a known history of SARS-CoV-2 infection but whose locations or circumstances put them at appreciable risk of acquiring COVID-19 or SARS-CoV-2 infection.
The primary goal of the VIRIONUM project is to analyze the association of clinical, socio-demographic characteristics of patients and their genetic polymorphism, inflammatory and other biochemical markers with disease progression and death in subjects with COVID-19 disease. The research is an observational, cohort study with nested-case control design, including adult, male and female COVID-19 inpatients. Primary dependent variable will be outcome of disease, defined as discharge from the hospital or death. The outcomes and putative risk factors will be analyzed using binary logistic regressions. The proposed multi- and inter-disciplinary study should provide additional scientific evidence about risk factors for the development of severe forms of the disease and the COVID-19-related death.
The purpose of this study is to understand how to prevent COVID-19 spread in a school like the Mary Cariola Center (MCC) in Rochester, NY by answering questions like these: how do activities in the school alter chances of infection? Are there people infected with the COVID-19 virus who have no symptoms? How is spread of COVID-19 affected by vaccination rates? Is there any hesitancy to get the vaccine and what are the reasons? This information will be used to help keep the school open and the students and staff safe. Eligible participants are those that work at the Mary Cariola Center (MCC) and interact with the students at MCC who have a high risk of infection from COVID-19. The study lasts for up to 16 months.
Healthcare workers and COVID-19 patients may experience psychological distress consequent to the pandemic, and are at particularly elevated risk for experiencing posttraumatic stress disorder (PTSD), based on evidence from previous infectious disease outbreaks. The best-validated treatment for PTSD is exposure therapy. Exposure therapy help patients suffering from PTSD to revisit and overcome their traumatic experiences. Including virtual reality in exposure therapy has a long history in treating PTSD; and has been used to treat military veterans and first-responders following 9/11. The investigators are developing and testing a virtual reality platform to be used in treating healthcare workers and COVID-19 patients who develop PTSD resulting from their experiences in the COVID-19 pandemic. Participants will complete ten ninety minute sessions, twice a week for five weeks aimed at mitigating their symptoms of PTSD. The pilot study will aim to demonstrate the feasibility and the tolerability of the virtual reality intervention in these populations.
This study aims to enroll patients with acute infection with Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) who do not meet criteria for hospital admission according to protocols developed by the Honduras Ministry of Health (MOH). Patients who are triaged to home must also be over the age of 60 years or have one high risk comorbidity and be over 45 years in order to meet inclusion criteria. These patients will be randomly assigned to one of four home-based care strategies, which may or may not include regular blood oxygenation monitoring and provision of alcohol-based hand-rub. Patients will be followed until resolution of their acute illness, and data will be collected on feasibility, impact and acceptance of the intervention. Some patients will be followed for up to one year to monitor for post-Coronavirus Disease 2019 (COVID-19) symptoms.
