Filter by:This study will assess the safety and immunogenicity of AG0301-COVID19 in healthy adult volunteers.
The purpose of this prospective, Phase 2, multicenter, blinded, randomized placebo controlled study is to demonstrate that early treatment with mavrilimumab prevents progression of respiratory failure in patients with severe COVID-19 pneumonia and clinical and biological features of hyper-inflammation.
When the COVID-19 virus infects a person, it enters the lung epithelial cells of its host and uses its genetic material to replicate. The pulmonary epithelial cells of a part of the population, known as "secretors", are capable of expressing the antigens of the "ABO" system on their surface. This secretory status can be established by determining the antigens of the Lewis blood group system. When the virus replicates in an "secreting" individual, the antigens of the "ABO" system of the infected individual will be present on the surface of the viruses formed in his/her lungs. It was shown in 2003 that the response of a given individual to the transmission of a virus depends on his/her blood group and on the antigens of the "ABO" system carried by the virus. A patient of group "O" would thus defend himself much better against a virus carrying antigens of blood group "A", the natural antibodies "anti-A" of the patient reducing the ability of the virus to bind to its specific receptor on pulmonary epithelial cells, to penetrate them to replicate itself. The first data collected in Wuhan (China) seems to confirm this hypothesis. A COVID-19 virus transmission model can therefore be established on the basis of blood groups. In order to reduce the spread of the virus among nursing staff, it is possible to establish a preferential algorithm for patient management based on the "ABO" and "Lewis" blood groups of patients and "ABO" of nursing staff in health care units, if operational and human conditions allow.
This study tests different messages about vaccinating against COVID-19 once the vaccine becomes available. Participants are randomized to 1 of 12 arms, with one control arm and one baseline arm. We will compare the reported willingness to get a COVID-19 vaccine at 3 and 6 months of it becoming available between the 10 intervention arms to the 2 control arms. Study participants are recruited online by Lucid, which matches census based sampling in online recruitment.
The purpose of this research study is to evaluate and improve a rapid COVID-19 test. The test is designed to identify people who are most contagious and likely to spread the virus to others. This test will be performed at various locations in the Madison area using a mobile laboratory or standard lab space for processing. Saliva samples can be collected and processed at these locations or participants can self-collect at home and drop their samples off at designated locations for same day processing. Results of potential findings of clinical significance will be communicated to the participants by a physician with appropriate expertise on the study team. Individuals with a potential finding of clinical significance will be encouraged to self-isolate and obtain a diagnostic test at their earliest convenience. No results will be given if the test is negative. If the participant consents, advanced molecular testing such as PCR or viral sequencing can be done and results can be shared via online databases, presentations and publications along with the date, site and county of collection to help facilitate tracking the spread of the virus.
This study will study the potential utility of the Quantra QPlus System in patients inflicted with COVID-19 disease.
The PREPARE-IT investigator-initiated trial program is a simple, pragmatic, therapeutic strategy evaluating pure icosapent ethyl (IPE) at initially higher doses intended to reduce infection rates and subsequent morbidity and mortality among subjects at high risk of infection due to COVID-19 (prevention arm), and to reduce the hospitalization rate and complications in patients with a positive diagnosis of COVID-19 (treatment arm).
The objective of this study is to look for the presence of SARS-CoV-2 in the semen of patients diagnosed with COVID+ based on RT-PCR analysis of nasopharyngeal swabs.
Covid-19, the infection caused by a novel corona virus detected in December 2019 in Wuhan (Hubei province), is now a pandemic announced by World Health Organization, raising concerns of widespread panic and increasing anxiety in individuals. This outbreak results in mass quarantine in Egypt since middle of March 2020. Brooks et al. (2019) reviewed and reported quarantine could bring "post traumatic stress symptoms, confusion, and anger. Stressors included longer quarantine duration, infection fears, frustration, boredom, inadequate supplies, inadequate information, financial loss, and stigma.". Many universities decided to suspend in-person classes and evacuate students in responding to the intensifying concerns surrounding Covid-19. This action can lead to negative psychological consequences among college students. Oral health related behavior and attitudes habits correlate with oral health status and can be considered to be its predictors . There is a claim of potential connection between high bacterial load in the mouth and complications associated with Covid-19 infection. Bacteria present in the meta genome of patients severely infected with Covid-19 included high reads for Prevotella, Staphylococcus, and Fusobacterium, all usually commensal organisms of the mouth. Over 80% of patients in ICU exhibited an exceptionally high bacterial load. Accordingly, the investigators assume that good oral hygiene better to be maintained during a Covid-19 outbreak in order to reduce the bacterial load in the mouth and the risk of a bacterial super infection in case of catching the infection . While there seems to be a common belief that psychosocial stress affects oral hygiene behavior, this assumption has rarely been proved9 Dental students, as the future providers of dental care, are ex¬pected to be role models for their patients regarding the oral hygiene practice and they supposed to be aware of the importance of preserving the oral health. Thus, we intended to select them as our population to study how the level of anxiety during pandemic could affect the practice of oral hygien
Coronavirus disease-19 (Covid-19) had an unprecedented effect on both nations and health systems. Time series modeling using Auto-Regressive Integrated Moving Averages (ARIMA) models have been used to forecast variables extensively mainly in statistics and econometrics. The investigators aimed to predict the total number of cases for Covid-19 using ARIMA models of time-series analysis.
