Filter by:This is a randomized, phase Ⅱ, single-blind, randomized, parallel-group controlled clinical trial. The study plans to enroll subjects who have completed homologous primary vaccination with either inactivated or mRNA or Viral Vector COVID-19 vaccines (one or two doses) and have not been infected with COVID-19. All subjects will be evaluated for safety and immunogenicity after a single dose booster immunization with Recombinant COVID-19 variant Vaccine (Sf9 Cell) or inactivated COVID-19 vaccine (Vero cell) or mRNA vaccine or Viral Vector vaccine.
This is a phase 2, randomized, observer-blinded, placebo-controlled clinical study to evaluate the immunogenicity and safety of SARS-CoV-2 mRNA Vaccine (SYS6006）in healthy participants aged 18 or more.
Phase II, non-randomized, open-label, comparative, single center national trial in Guinea, aimed to assess the humoral vaccine immune response induced by BBIBP-CorV vaccine in 200 adults aged between 18 and 45 years or 55 or older, one month after receiving the complete COVID-19 vaccination schedule.
Healthcare systems around the world have faced tremendous stress because of the COVID-19 pandemic. Healthcare workers (HCWs) (ie. physicians, nurses, and support staff), who serve as the foundation of the healthcare system, report high levels of psychological stress and burnout, which will likely worsen as the pandemic continues. The consequences of stress and burnout can reduce quality of life for providers and lead to adverse health behaviors (poor dietary choices, reduced physical activity, increased alcohol intake, increases in weight etc.) among HCWs. In addition, burnout can have dire consequences on healthcare delivery effectiveness including poor quality of care and significant cost implications due to medical errors and HCW absenteeism and turnover. In fact, annual estimates of burn-out related turnover range from $7,600 per physician to >$16,000 per nurse. However, programs focused on reducing burnout in HCWs have the potential to reduce costs to the healthcare system by $5,000 per HCW per year. Maintaining and recovering psychological and behavioral well-being is essential to ensuring we have a workforce that is resilient to acute and ongoing stressors such as the COVID-19 pandemic, ensuring that they are capable of providing the highest level of quality and compassionate care to patients. In this project, we will strengthen the resiliency of the Northwestern Medicine (NM) healthcare system by implementing an online psychological well-being intervention (PARK). We will assess HCW willingness to engage in PARK, which has been shown in other populations experiencing stress (e.g. dementia caregivers, general public coping with COVID-19) to be effective. We will also assess if the PARK is effective in reducing stress and associated-burnout, absenteeism, and intentions to leave the workforce in a subset of 750 persons who have been participating in a study of HCWs at NM since Spring 2020. In the entire cohort, we will measure the psychological well-being, levels of burnout, health behaviors, absenteeism, and plans to leave the workforce at three time periods: the start, middle, and end of the study period and assess whether they differ by HCW characteristics including gender, race, and role in health care. Results from this study will provide much-needed information: 1) about the current state of psychological well-being and burnout among NM HCWs, now over 1 ½ years into the pandemic; 2) on the role of an online wellness intervention to improve well-being during a protracted pandemic; and 3) about the contribution of PARK to reduce burnout, HCW absenteeism and turnover, and potential impacts on costs. PARK has the potential to have a significant impact on not only NM HCWs but also to be generalizable to other healthcare organizations for addressing burnout and to contribute to lessons learned on how to support HCWs responding to future pandemics; ensuring resiliency in the healthcare delivery system. In addition, we will work with our already engaged stakeholder committee to ensure results can provide actionable policy and fiscal insights. Future opportunities will include collaboration with other healthcare systems to expand roll-out of the successful PARK intervention.
Since its inception, KPMP has developed sophisticated protocols for collection and analysis of human kidney tissue, and for collection of biofluids. Members of the consortium have wide-ranging expertise in conducting clinical studies, processing kidney tissue, advanced structural and molecular analysis and complex bioinformatics analysis, which will be used to leverage effectively as a group to better understand kidney disease. This joint protocol aims to synergize the COVID-19 study efforts of KPMP academic research centers, to collectively study COVID-19, including its renal presentation using kidney tissue and/or biofluids from patients suffering from COVID-19. This will increase the breadth and depth of data available to the public to expedite discoveries, identify therapeutics, and improve outcomes for patients with COVID-19. It will additionally bring the expertise of KPMP investigators to bear against this pandemic.
The study is a randomized, double-blind, and positive-controlled Phase III booster study. It will evaluate the immunogenicity and safety of one dose of SCTV01C or SCTV01E as booster compared with either one dose of Sinopharm inactivated COVID-19 vaccine (Cohort 1) or one dose of Comirnaty (Cohort 2).
The objective of this study is to evaluate the effectiveness of SCTV01E in participants aged ≥18 years.
The main aim of this study is to evaluate the efficacy of S-217622 versus placebo among outpatient adults with mild and moderate COVID-19 starting intervention within 3 days of symptom onset.
The study aims to characterize the community burden (including the clinical features) and transmissibility of SARS-CoV-2 within the context of a functional antibody response. In addition,the study will assess the effect of the interaction of SARS-CoV-2 with influenza virus and RSV on disease severity and transmission dynamics. A household-level prospective cohort study will be conducted in one rural and one urban community located in Mpumalanga Province and North West Province, respectively. The study will be conducted for 12 months of intensive follow up (July 2020 to August 2021) with a post-intensive follow-up continuing for a further 16 months (until December 2022). Two hundred households; 1,000 study participants of all ages; will be randomly selected from a list of 327 hoseholds that participated and successfully completed a 10-months follow-up period in a study similar to that currently proposed, but directed at community burden and transmission dynamics of influenza, respiratory syncytial virus and other respiratory pathogens. Each household and household member will be enumerated and the HIV infection status and the level of immunosuppression of HIV-infected individuals will be assessed. Each household member will be followed twice per week during the intense follow-up period (12 months) of the study. During this period upper respiratory tract samples will be collected irrespective of presence of symptoms and data on key symptoms, healthcare seeking, hospitalization and death will be captured at each follow up visit. Respiratory samples will be tested by reverse transcriptase real-time polymerase chain reaction (rRT-PCR) for SARS-CoV-2, influenza and RSV, and selected samples will be cultured and sequenced. An infection risk questionnaire will be administered to all study participants at enrollment and every month thereafter. Sera will be collected at enrollment and every 2 months during the 12-month intense follow-up period from all participants. In addition, sera will be collected every 2 months for a further 6 months following the 12-month intense follow-up period from study participants that tested positive for SARS-CoV-2 by rRT-PCR on respiratory specimens at 14, 16 and 18 months and from all study participants at 18 months. Sera will be tested for the presence of SARS-CoV-2, influenza and RSV antibodies. Wearable proximity sensors will be deployed for 8-12 days in each household over the 6-month intense follow-up period.
The measures to control the transmissibility of the Covid-19 pandemic have changed the daily routines of the population, increasing sedentary lifestyles, decreasing outdoor physical activity and limiting contact with neighbors, family and friends. This could be having negative consequences for the health of vulnerable people. The investigators want to know how this situation has affected the health of people aged 75 years or older and their caregivers and how the circumstances experienced may mark new care needs. To this end, will be analyzed clinical data, follow up people who have become ill with COVID-19 and those who have not, and interview groups of caregivers and patients to hear about the personal impact of the pandemic on them. This will allow us to explore what changes are needed in health care to achieve an improvement in the health and quality of life of this population. CUIDAMOS+75 seeks the commitment of the population and of the different people in charge of the health services from the very beginning.
