Filter by:According to the comprehensive evaluation, the completion of vaccination and the prevention and treatment strategy of integrated traditional Chinese and western medicine have obvious advantages in improving the symptoms of infection in patients with autoimmune diseases, shortening the course of disease and controlling disease activity, and can play a positive role in the whole process of epidemic prevention and treatment. Now the investigators plan to conduct multi-center clinical and basic research to observe the preventive effect and safety of the vaccine on COVID-19, as well as the preventive effect of the combination of traditional Chinese medicine, in order to obtain high-quality evidence-based evidence and provide scientific basis for the clinical value of the drug.
The COVID-19 pandemic has had an outsized impact on individuals with underlying social and medical vulnerability, leading to increased rates of severe disease, hospitalization, and death in these groups. Participants with underlying immune compromise, such as those with multiple myeloma, represent one such group. The advent of vaccines against SARS-CoV-2 has significantly limited morbidity and mortality across all groups, but the effectiveness of vaccination in individuals who are less likely to mount sufficient antibody response is uncertain. For this reason, booster vaccines have been recommended for those with underlying immune compromise. However, several key gaps remain in our understanding of how to best protect these individuals. There is a dearth of real-world evidence about the effectiveness of vaccination and boosters in patients who are immunocompromised, and very little information specifically about the recently approved mRNA boosters. Additionally, rates of vaccination and booster uptake in the United States remain low. A rapid, decentralized method of ascertaining information related to booster vaccine response and adverse events related to vaccines and COVID-19 infection is critical not only to answer questions about the booster vaccines, but to develop an infrastructure for answering similar questions about future vaccines or other diseases.
The primary purpose of this study is to assess the feasibility and acceptability of a coping and resilience intervention for adolescents in school settings named CERIA, in the post-coronavirus disease 2019 or COVID-19 era. Whereas the secondary purpose of this study is to assess the effect of the intervention among adolescents on several outcomes, including posttraumatic stress disorder (PTSD) symptoms, defensive coping, courageous coping, social support, resilience, and health-related quality of life (HRQOL), in the post-COVID-19 era, at baseline or pre-test (one week before), right after/immediate effect or post-test (one week after), and one-month follow-up or short-term effect (one month after intervention). The research questions in this study include the following: - Is CERIA feasible for adolescents in the post-COVID-19 era? - Is CERIA acceptable for adolescents in the post-COVID-19 era? - What is the effect of CERIA on PTSD symptoms, defensive coping, courageous coping, social support, resilience, and HRQOL in adolescents in the experimental group compared to those in the control group in the post-COVID-19 era? - Are there any differences in the mean scores of PTSD symptoms, defensive coping, courageous coping, social support, resilience, and HRQOL between the experimental and control groups at: - one week before, - one week after, and - one month after CERIA? Participants in the experimental group will be given six-weekly 45-60 minutes CERIA sessions, whereas participants in the control groups will be treated as active control. Researchers will compare the experimental and control groups to see the effect of the intervention (CERIA) to decrease the adolescents' PTSD symptoms and defensive coping and increase courageous coping, social support, resilience, and HRQOL at three different time points: one week before intervention, one week after intervention, and one month after the intervention.
This is double-blind,randomized, single and multiple dose trial to evaluate the pharmacokinetics(PK), safety, tolerability and drug-drug interaction of RAY1216, and the effect of food on RAY1216 Pharmacokinetics.
Defining the antibody response to SARS-CoV-2 will be essential for understanding disease progression, long-term immunity, and vaccine efficacy. Investigators designed a study investigating the neutralizing antibody response among post-infected and post-vaccinated individuals to determine how the spike protein neutralizing antibody correlates with natural infection and vaccination and how mutations of viral strains affect associated antibodies. New Taipei City Municipal TuCheng Hospital established a special infectious pneumonia ward in May 2021 to treat patients infected with symptomatic SARS-CoV-2 patients. During the period, 97 patients were admitted and enrolled. In light of the current timing of the pandemic, most published serological studies are predominantly cross-sectional or, at most, include a longitudinal follow-up. Cognitive function and PhenoAgeAccel will be examined for SARS-CoV-2 N and S titers decline trend analysis to correlate long-COVID brain fog or early decline of N and S antibodies.Therefore, investigators designed a three-year longitudinal study to detect patients' SARS-CoV-2 neutralizing and spike antibodies.
This study focuses on the population of malignant lymphoma patients who are also in clinical research. Through a real world cross-sectional survey of infection and death risk during the COVID-19 pandemic in Guangzhou from December 2022 to January 2023, this study aims to clarify the risk, level and mortality of lymphoma patients infected with COVID-19 during their clinical research, and provide necessary research data for Chinese lymphoma patients during the COVID-19 pandemic,
The Peking University Health Cohort in Anning, Yunnan (PKUHC-AN) is a prospective cohort study carried out in Anning, Yunnan. The primary aim of this study is to investigate the impact of COVID-19 on older adults' health, and to provide high-quality evidence of real world research for the optimization of prevention and control strategies of COVID-19 and other emerging infectious diseases. Data will be collected regarding health status, history of COVID-19 infections and vaccines, lifestyle and socioeconomic characteristics, as well as the short- and long-term health outcomes.
The purpose of this study is to investigate the efficacy of orally administered nirmatrelvir/ritonavir compared with placebo/ritonavir to improve quality of life in non-hospitalized adult participants suffering from post-acute COVID-19 syndrome.
COVID-19 can trigger a dysregulated immune response, and previous studies have shown that immune modulation can improve outcomes in hospitalized patients. This trial is designed to determine whether intensification of immune modulation early in the course of the disease (while patients are on low flow oxygen) with abatacept (active arm) combined with standard of care (SOC) improves recovery as compared with placebo + SOC (placebo arm). For both groups, intensification of immunomodulation will be provided as part of SOC in case of signs of disease progression (patient requires high flow nasal oxygen (HFNO) or more support) and/or if the patient has rapidly increasing oxygen requirement.
To establish the efficacy of a community-based POL (Popular Opinion Leader) intervention with two different trainings designed to increase COVID-19 vaccine and booster uptake and reduce hesitancy among social networks of Black individuals with rheumatic conditions. The investigators will also determine the structure and composition of the personal and outreach social networks of POLs.
