Filter by:The purpose of this study is to evaluate the safety and efficacy of mRNA COVID-19 vaccines in: • People with prior COVID-19 (SARS-CoV-2 infection) who were in the ACTIV-2/A5401 study. And • People who have never had COVID-19 (SARS-CoV-2 infection).
Surveys administered to subjects who have recovered from COVID-19 to assess how effective their treatment was.
Hip fracture in the elderly is a worldwide public health issue and a medical challenge for early postoperative rehabilitation. More than 2 million people are treated annually with an annual incidence between 100 and 300/100,000 (USA, Europe, China), resulting in a cost of billion dollars and a strain on most surgical facilities. In this context, an early surgical management of patient with fracture within the first 24-48h has been shown to reduce morbidity, length of hospital stay and mortality. During the Covid-19 pandemics, a higher risk of 30-day mortality has been reported in patients with pre-operative SARS-CoV-2 infection diagnosed 0-2 weeks, 3-4 weeks and 5-6 weeks before surgery compared with patients who did not have a pre-operative SARS-CoV-2 infection. However, this risk seems to disappear in patients diagnosed with SARS-CoV-2 ≥ 7 weeks before surgery. These findings led to propose delayed elective surgery when the benefit-risk ratio was acceptable (cancer, cardiac surgeries). However, delaying surgery in COVID-19 patients (with high risk of immune and thrombotic disorders) with hip fracture could be questionable as the risk related to COVID-19 could be counteracted by the risk delayed surgery. For assessing the mortality risk related to hip fracture surgery associated with COVID-19, we decided to use the French national hospital discharge records database for comparing the 30-day postoperative mortality in patients with hip fracture and with or without an hospitalization for SARS-COV-2 infection in the 30 previous days before surgery.
The study is designed to evaluate the safety, reactogenicity and immunogenicity of three groups ages ≤18 - >12, ≤12 ->6, ≤ 6 - >2 years of healthy volunteers who receive two doses of the whole virion inactivated SARS-CoV-2 virus vaccine (COVAXIN®) 28 days apart. Data will be un-blinded to the third party bio-statistician and an interim analysis will be performed on day 56 for Immunogenicity, Safety and submitted to CDSCO.
For an antiviral agent to act as an effective biological barrier on nasal mucosal surface, the formulation preferably has to be maintained on the site of action for several hours, and the nasal spray dispenser can be utilized for administering the solution to the upper respiratory tract. A "first-in-man" clinical study of the nasal spray containing anti-SARS-CoV-2 antibodies derived from bovine colostrum was conducted. The study on healthy volunteers was undertaken to evaluate how long the bovine antibodies would be maintained on the nasopharyngeal surface after administration of nasal spray. In addition, the study enabled to determine which of the two concentrations of antibodies should be used in the final nasal-spray formulation. The volunteers were followed up for 4h after administration of antibody spray and sampling was done at different time-points during this period. The concentration of antibodies from patient samples was measured using ELISA analysis. In addition, as this was a "first-in-man" study any adverse events following the administration of spray were also monitored.
The world is currently facing a crisis because of this potentially fatal situation of the COVID-19 epidemic without proven efficacy for any drug treatment, while the vaccination is not yet. This epidemic is caused by a new betacorona virus, now called SARS-CoV-2. The most common symptoms reported are fever, cough or chest tightness, and dyspnea. Most cases have a mild course
To evaluate the analytical and clinical sensitivity and specificity of antigen tests performed as oropharyngeal swabs, outer nasal swabs, saliva swabs or breath tests including self-tests for SARS-CoV-2 towards standard RT-PCR testing. For each test 200 SARS-CoV-2 positive and 200 SARS-CoV-2 negative individuals previously defined by RT-PCR are tested. When tested an additional RT-PCR test is performed to verify status. Analytical sensitivity and specificity is determined on 210 SARS-CoV-2 positive samples with known Cq and 100 SARS-CoV-2 negative samples. 30 companies with a total of 55 tests participate in this nationwide study.
COVID-19 is respiratory disease caused by the severe acute respiratory coronavirus 2 (SARS-CoV-2), a novel coronavirus which has spread rapidly across the world with over 149.9 million laboratory confirmed cases and over 3.1 million reported deaths since December 2019. Approximately 4-8% of hospitalized patients with COVID-19 have co-infection with bacterial pathogens however there is widespread and often broad-spectrum antibiotic use in these patients. This is a prospective, multi-center, non-inferiority pragmatic clinical trial of antimicrobial stewardship prospective audit and feedback versus no antimicrobial stewardship intervention on physicians attending to patients with proven SARS-CoV-2 infection confirmed by nucleic acid testing in the preceding 2 weeks of hospitalization for acute COVID-19 pneumonia. Prospective audit and feedback is the real time review of antibacterial prescriptions and immediate feedback to prescribers to optimize antimicrobial prescriptions. Hospital beds will be stratified by COVID unit and critical care unit beds, and will be computer randomized in a 1:1 fashion into 2 arms (antimicrobial stewardship intervention versus no antimicrobial stewardship intervention) prior to study commencement at the participating site. Patients hospitalized to study-eligible beds will be followed for primary and secondary outcomes. The objective of this study is to determine the effect of an antimicrobial stewardship intervention (prospective audit and feedback) on clinical outcomes in patients hospitalized with acute COVID-19.
The SARS-Cov2 virus was identified in china at the end of 2019 and spread worldwide causing a global pandemic. Current research showed that SARS-Cov2 virus invades human cells via the receptor angiotensin-converting enzyme 2 (ACE2) through scRNA-seq data analyses. The study identified the organs that are at risk and are vulnerable to SARS-CoV-2 infection. Therefore, cells with ACE2 receptor distribution may become host cells for the virus and cause inflammatory response in related organs and tissues, such as the tongue mucosa and salivary glands. These results suggest that oral mucosa could be a target of SARS-CoV-2 infection
In April 2020, a meta-analysis on the long-term sequelae of respiratory syndromes related to seasonal coronaviruses (SARS and MERS) showed a significant alteration in quality of life, with in particular a decrease in physical and emotional capacities and a deterioration of social life. An improvement of the quality of life is evidenced after 6 months but without reaching the level usually observed in healthy people. The impact of SARS-CoV-2 infection on quality of life can be explained by the persistence of pleomorphic symptoms in the medium to long term. In the military population, the majority of SARS-CoV-2 cases present minor to moderate forms of the disease. Military personnel have living conditions that differ from those of the general population, in particular because of their geographic mobility, which may be responsible for isolation from the family. This isolation can be regular (we speak of "geographical celibacy" when the soldier is posted in a geographical area far from the family unit) and/or occasional, during missions on the national territory or outside. This singularity justifies a study on the impact of SARS-CoV-2 (COVID-19) infection on the quality of life in this specific population.
