Awake prone positioning has been reported to improve oxygenation for patients with COVID-19. Awake timed and repositioning is a novel method to improve patients' compliance and prolong the prone time. This study aims to explore the impact of timed prone and repositioning on the intubation rate and prognosis of COVID-19 patients with hypoxic respiratory failure.
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.
The goal of this observational study is to learn about the effects of coronavirus infection in patients with early-stage lung cancer. The main question it aims to answer is whether the interval of surgery and COVID-19 infection will affect the surgery and prognosis of the patients.
Evaluation of the efficacy and safety of ursodeoxycholic acid in blocking the transmission of infectious novel coronaviruses in a population of medical workers
Knowing that the vaccine antigen includes the ACE2 binding moiety (RBD), the hypothesis is that circulating vaccine antigen could reduce the enzymatic activity of ACE2, and thus increase circulating AngII concentration, monocyte ROS production and lymphocyte apoptosis. This hypothesis is supported by the fact that the Spike protein of SARSCoV-1, which uses the same receptor as SARS-CoV-2, induces a decrease in expression and activation of the Angiotensin II pathway in mice (Kuba et al. 2005).
This is a future-proof and randomized controlled clinical study on the clinical efficacy of graphene photothermal adjuvant therapy in Corona Virus Disease 2019(COVID-19) patients with mild symptoms. The objective is to examine the effect of graphene photothermal adjuvant therapy on the time line for such Corona Virus Disease 2019 patients to achieve a negative severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleic acid test result, and their duration of disease. Patients who meet study criteria will be randomized into the Grapheme adjuvant therapy combined with conventional therapy group (treatment group) and the conventional therapy only group (control group). Contrasted to the control groups, the treatment groups will undergo 30-min of graphene adjuvant therapy every day for 7 d.
All participants will be assessed for immunogenicity and safety endpoints and provide a blood sample before the administration of the first dose of IP. Blood samples will be collected on days 0, 9 (Groups 1, 3 and 4), 28,37 (Groups 2 and 4), 56, 90 and 180 to assess the neutralizing antibody titer against the SARSCoV-2 virus. A subset of 160 Participants (40 participants from each group) will be assessed for immunogenicity analysis, among these subset 10mL of blood and 5mL of saliva will be collected on days 0, 9 (Groups 1, 3 and 4), 28, 37 (Groups 2 and 4), 56, 90 and 180 to assess cell-mediated immunity and mucosal immunogenicity. Group 1 (COVAXIN® + COVAXIN®): In this group, 152 participants will be recruited who will receive COVAXIN® on day 0 and on day 28 via the intramuscular route. Group 2 (COVAXIN® + BBV154): In this group, 152 participants will be recruited who will receive COVAXIN® (Intramuscular) on day 0 and BBV154 (Intranasal) day 28. *Post 56 days of vaccination, participants with seroconversion rate less than 3 folds will receive another dose of COVAXIN® viaintramuscular route. Group 3 (BBV154 + COVAXIN®): In this group, 152 participants will be recruited who will receive BBV154 (Intranasal) on day 0 and COVAXIN® (Intramuscular) on day 28. *Post 56 days of vaccination, participants with seroconversion rate less than 3 folds will receive another dose of COVAXIN® via intramuscular route. Group 4 (BBV154 + BBV154): In this group, 152 participants will be recruited who will receive BBV154 on day 0 and on day 28 via the intranasal route.
The study aims to investigate the safety and immunogenicity of one dose vs two doses of a T-cell priming next-generation vaccine against Coronavirus disease.
The patients with coronavirus infection usually have fever, respiratory symptoms, headache, toothache, muscle soreness, physical decline, and so on, while others are asymptomatic patients. It is urgent to find drugs to improve the long-term rehabilitation of symptomatic patients with coronavirus infection and decrease the duration of viral shedding in both symptomatic and asymptomatic patients. This study aims to investigate the efficacy and safety of Lianhua Qingwen capsules in patients with coronavirus infection. The duration of viral shedding and symptoms before discharge, as well as the negative conversion ratio and disappearance ratio of main symptoms after 7-day treatment, will be evaluated. 6-month follow-up will be performed to evaluate the effect of Lianhua Qingwen on all infection events and the long-term rehabilitation of the symptoms induced by coronavirus infection.
The patients with Omicron infection usually have fever, respiratory symptoms, tachycardia, headache, toothache, muscle soreness, physical decline, and so on, while others are asymptomatic patients. It is urgent to find drugs to improve the long-term rehabilitation of symptomatic patients with Omicron infection and decrease the duration of viral shedding in both symptomatic and asymptomatic patients. This study aims to investigate the efficacy and safety of Lianhua Qingke tablets in patients with Omicron infection. The duration of viral shedding and symptoms will be evaluated. 6-month follow-up will be performed to evaluate the effect of Lianhua Qingke on long-term rehabilitation of all symptoms induced by Omicron infection, as well as infection events.
