Filter by:The coronavirus disease 2019 (COVID-19) which is caused by the virus SARS-CoV-2 has resulted in an ongoing global pandemic. It is unclear whether the relatively low number of reported cases of COVID-19 in people with CF (pwCF) is due to enhanced infection prevention practices or whether pwCF has protective genetic/immune factors. This study aims to prospectively assess the proportion of pwCF, including both adults and children with CF who have evidence of SARS-CoV-2 antibodies over a two-year period. This study will also examine whether pwCF who have antibodies for SARS-CoV-2 have a different clinical presentation and what impact this has on their CF disease. The proposed study will recruit pwCF from paediatric and adult CF centres in Europe. Serological testing to detect antibodies will be performed on blood samples taken at month 0, 6, 12, 18 and 24 with additional time-points if bloodwork is available via normal clinical care. Clinical data on, lung function, CF-related medical history, pulmonary exacerbations, antibiotic use, and microbiology and vaccination receipt, will be collected during routine clinical assessments. Associations will be examined between sociodemographic and clinical variables and serologic testing. The effects of SARS-CoV-2 infection on clinical outcomes and analyze end-points will be examined to explore any age-related or gender-based differences, as well as a subgroup analysis of outcomes in lung transplant recipients and pwCF receiving CFTR modulator therapies. As pwCF receive COVID-19 vaccination a comparison of the development and progression of anti-SARS-CoV-2 antibodies in pwCF following natural infection and vaccination SARS-CoV-2 over time will be performed.
Our main objective is to analyze the development of physical impact, mental health and blood profile over follow-up time during the 1st wave of the COVID-19. Besides, we aim to establish a database of post-COVID-19 based on simultaneous cortico-spinal magnetic resonance imaging data to identify high-risk patients with long COVID and prevent the neurological symptoms evolution, optimize the tactics of management in China.
The goal of this clinical trial is to learn about, test, and compare JCXH-221 in healthy volunteers. The main aims to answer are: - To assess the safety and tolerability of the JCXH-221 vaccine in healthy adult subjects - To identify an optimal dose for the JCXH-221 vaccine in healthy adult subjects - To assess the humoral immunogenicity of the JCXH-221 vaccine in healthy adult subjects - To characterize the cellular immunogenicity of the JCXH-221 vaccine in healthy adult subjects Participants for Phase I will be randomized to either JCXH-221 or placebo. In Phase 2, participants will be randomized to either JCXH-221 or a FDA approved Active comparator.
To further characterize Long COVID-19 by collecting data from individuals who already own wearable devices or are provided with a wearable device along with basic and enhanced educational materials to determine if both can improve Long COVID-19 symptom management and post-exertional malaise.
This study is to evaluate the safety and efficacy of umbilical cord mesenchymal stem cells Therapy for COVID-19.
This is a prospective observational study. In this study, we aim to investigate the effect of a recent past Covid-19 infection on the live birth rate in the frozen embryo transfer cycles
COVID-19 is an infectious disease caused by SARS-CoV-2 virus, causing millions of deaths around the globe since the beginning of the pandemic. COVID-19 vaccination was proven to be effective at reducing both mortality and development of severe COVID-19 after infection. Vaccine-elicited protection is particularly important for immunocompromised patients, as they are more susceptible to infections with their defective immune response, for instance, previous review had suggested that patients with malignancies and recipients of solid organ transplants may be at increased risk of developing severe COVID-19 disease and even death. To further complicate the scenario, there are two obstacles: firstly, immunocompromised individuals may have suboptimal response from vaccinations, as studies have shown that recipients of solid organ transplant have suboptimal or even are seronegative after the fourth dose booster vaccination . Secondly, with constant mutation of the SARS-CoV-2 viruses, new variants evolve over time, leading to reduction in vaccine efficacy and breakthrough infection in healthy individuals. Therefore, novel vaccine strategy should be considered to enhance the vaccine response in these immunocompromised individuals. In this study, intradermal injection instead of intramuscular injection for vaccine delivery is proposed, as the investigators have observed improved immunogenicity and few adverse events from previous experience of influenza vaccination. The study aims to evaluate the immunogenicity, safety and tolerability of intradermal COVID-19 vaccination in immunocompromised patients.
Mixed-method observational study: the impact of pandemic related changes in healthcare on quality of life and experiences with healthcare in Dutch patients undergoing surgery or another intervention during the covid pandemic (2020-2021). Phase 1: qualitative study to gain insight in relevant themes in Patient Reported Experiences Measures (PREMs) by conducting focus groups Phase 2: creating and validating a questionnaire based on themes identified in phase 1 Phase 3: questionnaire study among Dutch patients who underwent an intervention in 2020-2021 using the validated questionnaire of phase 2. The answers will be linked to data from national patients registries in surgery, cardiology, orthopedics and neurology.
The goal of this observational study is to describe the symptoms that persist for more than 12 weeks after the acute episode in participants who had COVID-19, and compare the functional, socioeconomic and occupational effects with a post-COVID-19 control group without persistent symptoms after the COVID-19 acute event. The main questions it aims to answer are: - What are the characteristics of symptoms that persist for more than 12 weeks in participants who have had COVID19 in the last year? - What are the health-related quality of life and psychosocial effects in participants with persistent symptoms of COVID-19, compared to a post-COVID-19 control group without persistent symptoms after the acute episode of COVID-19?
The objective of this prospective cohort study is to explore the association between the development of post-traumatic stress disorder (PTSD) in surgeons and anesthesiologists and postoperative prognosis in surgical patients they care for during the COVID-19 pandemic. There are 2 cohorts included in this study. The first cohort consists of registered surgeons and anesthesiologists in the study center. The development of PTSD will be evaluated with a series of questionnaires and scales. This cohort defines exposure (with PTSD). The second cohort consists of surgical patients managed by the surgeons and anesthesiologists in the first cohort. The postoperative outcome of these patients will be evaluated thus to explore the association between PTSD in physicians and adverse patient outcomes. The second cohort defines the outcomes( response).
