Active clinical trials for "COVID-19"

The current project is a prospective, multicentric cohort study aiming at a multidisciplinary assessment (pulmonary, cardiometabolic, sleep and mental health) of the consequences of infection by SARS-CoV-2, 3 months after the diagnosis in order to better characterize these complications. 400 patients with a positive diagnosis of SARS-CoV-2 will be included in the study 3 months after their diagnosis: They will be followed at 6 months, 1 year, 3 years, and 5 years, as function of their after-effects discovered at 3 months and their evolution.

Patients with COVID-19 diagnoses are treated under isolation in hospitals and with high-stress level. Currently, there is little information on the mental health implications of exposure amongst COVID-19 survivors and their family members. Research exploring the psychological impact amongst survivors of exposure to COVID-19 is desperately needed to understand the effects, mental health toll, and support required in survivors of COVID-19. This study aims to assess the psychological impact of the COVID-19 outbreak on COVID-19 survivors and their family members.

Experience from the 2003 Severe Acute Respiratory Syndrome (SARS) outbreak taught that healthcare workers (HCWs) often experience chronic stress effects for months or years after such an event, and that supporting HCWs requires attention to the marathon of occupational stress, not just the sprint of dramatic stressors that occur while infections are dominating the news. This study will test if the well-being of hospital workers facing a novel coronavirus outbreak is improved by adding either of two interventions: (1) Peer Resilience Champions (PRC): an interdisciplinary team of professionals who actively monitor for early signs of heightened stress within clinical teams, liaise between staff and senior management to improve organizational responsiveness, and provide direct support and teaching (under the supervision of experts in resilience, infection control, and professional education). Investigators will test the effectiveness of this PRC Intervention by rolling it out to different parts of the hospital in stages and comparing levels of burnout before and after the intervention reaches particular teams and units (a stepped wedge design). By the end of the study, PRC Support will have been provided to all clinical and research staff and many learners (> 6,000 people). Note that the provision of PRC support will be directed to the entire organization. The research portion of the study is the evaluation of PRC support through a repeated survey completed by consenting staff. Investigators will test the effectiveness of the PRC by measuring trends in burnout and other effects of stress over the course of the study in a subgroup of hospital workers (as many as consent, target ~1000 people) through an online questionnaire (called "How Are You?"). (2) The second intervention is an enriched version of the "How Are You?" Survey, which provides personalized feedback about coping, interpersonal interactions and moral distress. Participants will be randomized (1:1) to receive the shorter Express Survey (identifying data and outcome measures only), or the Enriched survey (all of the Express measures plus additional measures with feedback based on responses). It is hypothesized that both the PRC intervention and the Enriched Survey intervention will help prevent or reduce instances of burnout in HCWs.

The purpose of this clinical trial is to learn about the safety, tolerability and immunogenicity of BNT162b RNA-based SARS-CoV-2 vaccine candidates in adults to prevent COVID-19. For all cohorts (groups of participants), this study is seeking participants who are healthy (who may have preexisting disease if it is stable); All participants will receive a single dose of the study vaccine at the first study clinic and will return to the study clinic at least 4 more times. At each clinic visit, a blood sample will be taken. The study is about 6 months long for each participant. The vaccine candidates in this study are investigational but are very similar to BNT162b2 (Comirnaty), a COVID-19 RNA vaccine approved for use in the US and in many countries. For Cohort 1, this study included participants who were: 18 through 55 years of age have received 1 booster dose of a US-authorized COVID-19 vaccine, with the last dose being 90 or more days before Visit 1 of this study. All participants in Cohort 1 will receive 1 of the 2 study vaccines at a 30 microgram dose: BNT162b5 Bivalent (WT/OMI BA.2) or BNT162b2 Bivalent (WT/OMI BA.1). For Cohort 2, this study included participants who were: 12 years of age and older have received 3 prior doses of 30 micrograms BNT162b2, with the last dose being 150 to 365 days before Visit 1 of this study. Participants 12 through 17 years of age will receive BNT162b2 Bivalent (WT/OMI BA.4/BA.5) 30 micrograms. Participants 18 years and older will receive BNT162b2 Bivalent (WT/OMI BA.4/BA.5) at either a 30 microgram or a 60 microgram dose. For Cohort 3, this study included participants who were: 18 years of age and older have received 3 prior doses of 30 micrograms BNT162b2, with the last dose being 150 to 365 days before Visit 1 of this study. Participants will receive BNT162b2 Bivalent (WT/OMI BA.4/BA.5) 30 micrograms. For Cohort 4, this study is seeking participants who are: 18 through 55 years of age have received 3 or 4 prior doses of a US-authorized mRNA COVID-19 vaccine (and dose level), with the last dose being a US-authorized BA.4/BA.5-adapted bivalent vaccine and dose level at least 150 days before Visit 1 of this study. All participants in Cohort 4 will receive 1 of the 5 study vaccines at a 30 microgram dose: BNT162b2 Bivalent (Original/ OMI BA.4/BA.5), BNT162b5 Bivalent (Original/OMI BA.4/BA.5), BNT162b6 Bivalent (Original/OMI BA.4/BA.5), BNT162b7 Bivalent (Original/OMI BA.4/BA.5) or BNT162b7 Monovalent (OMI BA.4/BA.5).

This is a Phase II/III, randomized, double-blinded study in adults ≥ 18 years old who received 2 or more doses of inactivated COVID-19 vaccine to evaluate the efficacy, safety and immunogenicity of a booster dose of PIKA COVID-19 vaccine compared to the comparator inactivated COVID-19 vaccine. Phase II/III will be a competitive enrollment process in all participating countries. Once the target number of subjects is reached, the enrollment in all participating countries in the particular phase will be stopped.

This research is characterized as a cross-sectional observational study, which follows the recommendations of the STROBE instrument. Therefore, it is being performed at the Intensive Care Unit of Hospital Otávio de Freitas (HOF) in Recife/PE, with patients over 18 years of age who have a clinical diagnosis of COVID-19, using two methods of oxygen therapy (Nasal Oxygen Catheter and mask without rebreathing). That through clinical assessments of the disease, degree of severity of COVID-19, perception of respiratory effort and electromyography of respiratory muscles. The hypothesis of this study is that the higher the level of muscle activation and fatigue, the greater the risk of intubation and length of stay in the ICU. The rationale for the study is that Surface Electromyography is a widely used resource to analyze and compare respiratory muscle responses and thus provide prior treatment. Identifying which muscles undergo changes in patients with COVID-19 is essential to analyze and understand the likely functional changes of the respiratory system in COVID-19 and how they reflect according to their level of respiratory support and disease severity.

COVID-19 (Coronavirus Disease 2019) Registry of University Hospital of Ioannina. Retrospective datasource registry with quantitative and qualitative patient data from the hospital medical records. Epidemiological, clinical and laboratory parameters are recorded on 7 different time points (day: 1, 3, 5, 7, 9, 11, 15) concerning 793 variables of interest in an electronic (computerised) database. Patients are also followed-up after 90 days from hospital discharge (number of visits of follow-up depends on patient's health status) at the Post-COVID and Long-term effects of coronavirus (long COVID) outpatient clinic of University Hospital of Ioannina. Data from this outpatient clinic are also recorded in an electronic database (189 variables of concern for each patient)

Patients with chronic rheumatic diseases (such as systemic lupus erythematosus [SLE], rheumatoid arthritis [RA], ankylosing spondylitis [AS], juvenile idiopathic arthritis [JIA], poly/dermatomyositis [PM/DM], systemic sclerosis [SSc], systemic vasculitis, and primary Sjögren's syndrome [pSS]) are particularly susceptible to infectious diseases due to autoimmune disorder itself and its treatment (immunosuppressive therapies). Similarly, people living with HIV/AIDS (PLWHA) are predisposed to infections by different agents. The current 2019 Coronavirus Disease Pandemic-19 (COVID-19), caused by the SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) began in December 2019 in Wuhan, China, and quickly became a global health and economic emergency by taking to an unprecedented burden on health systems around the world. However, SARS-Cov-2 infection raised particular concern in patients with autoimmune rheumatic diseases (DRAI) since, due to chronic inflammatory immune dysregulation and the regular use of immunosuppressive drugs, these patients are considered to be at high risk of contracting SARS-CoV-2 and potentially evolving to a worse prognosis. The overlap between the COVID-19 pandemic and the HIV/AIDS pandemic also poses an additional challenge, as the impact of co-infection is not yet fully known. The response to vaccines for other agents, however, has already been described as compromised in PLWHA. Vaccination is the most effective preventive measure to control the spread of coronavirus and to reduce associated complications. Usually, live or attenuated vaccines are not recommended for patients with chronic rheumatic diseases using immunosuppressants. However, immunization with inactivated agents is strongly indicated, resulting, in general, in good immunogenicity and adequate vaccine safety, as well as without relevant deleterious effects on diseases. Vaccine efficacy studies are needed to verify the immunogenicity of the vaccine against COVID-19 in immunosuppressed patients with rheumatological disease and those with HIV-related disease considering the risk of greater severity. In addition, it is important to assess the safety of the vaccine in this population as well as the possibility of reactivating the rheumatological disease itself. The present study will evaluate the safety and immunogenicity of the CoronaVac (Coronavirus vaccine, Sinovac Biotech Ltd.) in patients with rheumatic diseases and PLWHA

The global pandemic caused by the SARS-CoV-2 virus is confronting the German health system with a novel pathogen. This means that a timely evaluation of all available results is required. In the field of intensive care in particular, there are significant gaps in knowledge, particularly with regard to delirium. In this respect, this study also serves directly to investigate the pathways of delirium outcome in COVID-19 patients.

The primary objectives of the study are: To assess the safety profile of the study vaccines in each study intervention group. To assess the neutralizing antibody profile after primary series vaccination in SARS-CoV-2-naïve adults. To demonstrate that a booster dose of monovalent or bivalent SARS-CoV-2 vaccine given to adults previously vaccinated with an authorized/approved COVID-19 vaccine induces an immune response that is non-inferior to the response induced by a twodose priming series with the monovalent vaccine, and superior to that observed immediately before booster. The secondary objectives of the study are: To assess the neutralizing and binding antibody profiles after primary series vaccination at pre-defined time points during the study. To assess the neutralizing and binding antibody responses of booster vaccination. To describe the occurrences of laboratory-confirmed symptomatic COVID19 after primary series and booster vaccination. To describe the occurrences of serologically-confirmed SARS-CoV-2 infection after primary series vaccination.
