Filter by:In this trial the researchers plan to recruit 4,000 volunteers to be randomly allocated either wearing face masks in public spaces where they are close to other people, or not wear face masks in such circumstances. For each participant the trial period is 2 weeks, after which they will be asked to complete a brief questionnaire which includes questions about whether they experienced the common cold, influenzas or COVID-19 symptoms during the trail period.
With the knowledge of currently transmitted omicron variant being less virulent, over 90 percent of the Chinese population is fully vaccinated, and the Chinese health workers have sufficient experience treating the illness. China 's epidemic prevention and control has entered a new stage to restore the normal functioning of society and basic medical services, On Dec, 7, China released a circular on further optimizing its COVID-19 response, announcing 10 new prevention and control measures.This has marked the watershed for sharply increased number of elective surgical patients diagnosed with COVID-19 during preoperativley, fully recovered or during recovery. Beijing faced a wave of omicron infection starting that would result in of a wide range of population infections. At which time there is limited evidence regarding the optimal timing of surgery following SARS-CoV-2 infection especially for omiron among Chinsese patients .This study intends to explore the relationship between the incidence of postoperative complications after elective surgery and COVID-19 infection in Peking Union Medical College Hospital, and provide data support for the policy formulation of elective surgical timing for patients after COVID-19 infection.
This is prospective multicentre comparative randomized double blind placebo controlled study conducted in 6 medical facilities.The objective of the study is to assess the safety and efficacy of the sequential therapy with BRAINMAX®, solution for intravenous infusion and intramuscular injection, and BRAINMAX®, capsules for the treatment of patients with asthenia after having the novel coronavirus infection (COVID-19)
Secondary bacterial pathogen infection has been demonstrated to aggravate COVID-19 clinical outcomes. Bacterial infections acquired during a hospital stay are likely resistant to several antimicrobial medicines, making COVID-19 patient management difficult. As a result, it is believed that aerosolized colistin might be a viable choice for treating secondary bacterial infections caused by gram-negative resistant strains in individuals who also have COVID-19 infection.
This is a randomized, placebo-controlled, double-blinded phase I study, designed to evaluate the safety including reactogenicity and immunogenicity of this investigational DNA vaccine delivered intramuscularly by in vivo EP in human adults. The vaccine doses will be given to healthy adults aged 18 to 60 years, who have been previously vaccinated against COVID-19 with 3 doses of either Comirnaty® or Spikevax®, or both in any combination ≥3 months ago.
Immunomodulation of local immune response at the oropharyngeal mucosa can hypothetically activate mucosal immunity, which can difficult SARS-CoV-2 main immune evasion mechanisms in early stages of the disease and send an effective warning to the adaptive immune system. There are previous studies on immunotherapeutic management of upper respiratory tract infections with olive polyphenols. The investigators would like to study if participants following oromucosal immunomodulation with tiny quantities of high polyphenolic olive oil (early harvest olive oil) could have more possibilities to have less severe symptoms and a better outcome after SARS-CoV-2 infection.
Ursodeoxycholic acid is a clinically approved drug which widely used in patients with chronic liver diseases, especially liver transplantation. In China, the COVID-19 infection is in an epidemic state, and the population is generally susceptible to COVID-19. More attention needs to be paid to the prevalence and severity of people taking immunosuppressants after organ transplantation. Recent cohort studies and experiments based on tissue cells, animals and human beings suggest that ursodeoxycholic acid has the potential ability to prevent the entry of COVID-19 into cells, revealing that Ursodeoxycholic acid may be used to prevent the COVID-19 infection. Based on the medical records of patients( already registered on the management website http://www.cltr.org or www.csrkt.org.cn) who received organ transplantation in the First Affiliated Hospital of Xi'an Jiaotong University and the First Affiliated Hospital of Zhengzhou University, this project intends to collect information and data from patients received organ transplantation, aim to understand the COVID-19 infection and severe condition of organ transplantation patients, also explore whether ursodeoxycholic acid has preventive and therapeutic effects on COVID-19 infection and severity rate in patients. This research provides a theoretical basis for further standardizing the prevention and treatment of COVID-19 in patients received organ transplantation.
This is an open-label study. This study includes 2 parts, in which part 1 is a relative BA study, Part 2 is a DDI study. Part 1 and Part 2 could be performed in parallel.
In our study, yoga asana and pranayama practices, which will be applied by video call from computer or phone, will be advantageous in terms of time, transportation and access to asthmatic children whose anxiety and anxiety levels increase during the COVID-19 period, whose access to hospital services is difficult, and whose physical activity level decreases due to the increase in screen time. It was aimed to examine the effects of these group exercises on Asthma Control, Functional Capacity, Physical Fitness, Physical Activity and Quality of Life. In the randomized controlled study, the treatment and control group will be determined by the closed envelope method, the control group will be placed on the waiting list and yoga will be practiced at the end of the study. The first and final evaluation will be done face to face in a clinical setting. The total duration will be 12 weeks, 3 days a week and 36 sessions between 8-8:40 in the evening. Researchers who will do yoga have a certificate of practice. Patients will be followed up in Hacettepe University Medical Faculty Asthma Allergy Clinic.
According to the WHO, contact tracing - along with robust testing, isolation, and care of cases is a key strategy for interrupting chains of transmission of SARS-CoV-2 and reducing mortality associated with COVID-19. Contact tracing, however, has a number of challenges. These include incomplete identification of contacts, inefficiencies in paper-based reporting systems, complex data management requirements, and delays in the identification of contacts and testing of contacts. In many settings, contact tracing has proven to be too resource-intensive to implement at scale, especially with higher levels of community transmission, highlighting the need for more efficient contact tracing approaches. Digital tools afford the possibility of strengthening contact tracing for COVID-19, in a more efficient way. However, there is limited evidence of the effectiveness and impact of these tools in the COVID-19 response, including contact tracing. This study proposes to compare the cascade of care between two strategies for COVID-19 contact tracing of SARS-CoV-2 infected index patients in Cameroon. In one strategy (intervention), the health facilities and health district testing units will implement contact tracing using a digital tool developed to support the tracing and testing of contacts (addition of a digital contact tracing module to the main platform for COVID-19 testing in Cameroon (Mamal Pro app)). This strategy will be compared to the standard contact tracing process (control), based on the current routine approach (use of the Mamal Pro application without the digital contact tracing module).
