This phase II trial studies low-dose radiation therapy as a treatment for patients with severe COVID-19 pneumonia to improve clinical status.
To explore the relationship between SARS-CoV-2 infection in different time before operation and postoperative main complications (mortality, main pulmonary and cardiovascular complications) 30 days after operation; To determine the best timing of surgery after SARS-CoV-2 infection.
VIDO has developed a vaccine called COVAC-1. The COVAC-1 study vaccine contains a portion of the SARS-CoV-2 spike protein, called S1. The spike protein is the part of the virus that is responsible for attaching to the surface of host cells. COVAC-1 contains a TriAdj adjuvant. An adjuvant is a compound that is added to a vaccine to help the vaccine produce a better immune response. The vaccine is expected to stimulate the body to make antibodies against the S1 protein. The antibodies will recognize the viral spike protein if the body is exposed to the virus and prevent COVID-19 illness. In animal studies, the immune response generated by the COVAC-1 vaccine was able to protect the vaccinated animals against a severe SARS-CoV-2 infection. The COVAC-005 Study is a Phase I, multi-centre trial of a SARS-CoV-2 vaccine booster. This is a randomized, observer-blinded, and placebo-controlled study to assess the safety and immunogenicity of COVAC-1 booster dose administered once in generally healthy adults 18-65 years of age who have received a minimum of 2 doses of an authorized COVID-19 vaccine at least 4 months prior to Day 0. The study will follow a dose-escalation design to test the safety and immunogenicity of three dosage levels (10, 25 and 50 µg). In each dose escalation group participants will be randomized in a 3:1 ratio, to receive either the investigational product or a placebo, respectively. Stratification will be according to the Investigational product dose received. Sub-analysis will be completed in two age groups, 18-54 and 55-65 years. Study participants will be initially randomized to the lowest dose of 10 µg or placebo. After approval by the Sponsor and based on the recommendations from the DSMB following the Day 7 safety analysis, new study participants will be allowed to be randomized in the higher dose escalation group of 25 µg. Approval will also be sought from the Sponsor, based upon the DSMB recommendation, to proceed with the higher dose of 50 µg. Within each dose escalation group of 16 participants (12 active vaccine recipients, and 4 placebo recipients) it is proposed to randomize a first cohort of 4 participants, including at least 3 active vaccine recipients, and pending no holding rule is met after 48 hours, as determined by the post-injection phone call, the remaining 12 participants within that dose escalation group will be randomized.
The purpose of this waitlist-controlled, single-blind, one-way crossover, pilot trial is to evaluate the potential effects of ~8 weeks of chiropractic care on patient-reported fatigue and the autonomic nervous system in adults with long COVID. This study will allow us to estimate the standard deviation of the primary endpoint in our population with which a formal power calculation for a future randomized, controlled trial can be performed.
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.
Real clinical practice register of Albuminuria detection in patients with previously undiagnosed chronic kidney disease
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.
The goal of this study is to explore whether a chatbot based on NLP techniques has better educational effect than printed booklets on knowledge of COVID-19 and its vaccination.
To investigate whether treatment with Azvudine reduces the risk of severe illness or death in patients who are at a potential risk of progressing to severe COVID-19 infection.
This study aims to observe the impact of COVID-19 infection on the reproductive function and assisted pregnancy outcome of infertile couples undergoing assisted reproductive technology and to determine which factors are related to the clinical pregnancy rate. A multicenter, prospective, observational cohort study was adopted. Infertile couples who met the selection criteria were included in this study, the SAS anxiety self-rating scale was filled out, the basic situation was observed, and blood samples and related tissues were collected for testing. Relevant reproductive function, laboratory, clinical, and psychological indicators were collected, and the correlation between the above indicators and the outcome of the ART-related pregnancy were analyzed.
