Filter by:This study aims to determine whether patients with different real-time reverse transcriptase-polymerase chain reaction (PCR), chest computed tomography (CT) and laboratory findings have different clinical outcomes.
It is known that enhances wound healing by oxidative stress and supports immune system besides it is cheap and has not any side effects. Aim of the study is to prevent pulmonary fibrosis by using ozone therapy as a supportive therapy on the patients who have pneumonia and ground glass opacity on thorax CT both in ICU and wards. Patients will follow for a year.
This is a quasi-experimental study with risk-based allocation. Public security and education professionals from the state government will be included. In the initial evaluation, the presence of comorbidities associated with an increased risk of serious disease due to COVID-19 will be evaluated, according to the national plan for the implementation of vaccination against COVID-19. Those with at least one of these comorbidities will be invited to receive the study vaccine in two doses, with an interval of 28 days (±7 days). Participants with low risk (without comorbidities as a risk factor for severe COVID-19 according to the national plan for the implementation of vaccination against COVID-19) will not receive the vaccine within the scope of the research project. If, after 12 months, the participant in the low-risk group (no vaccine) has not received CoronaVac, or any other vaccine available, he/she will receive the vaccine, exactly as offered in the other group (two doses of CoronaVac with an interval of 28 days - with a tolerance of 7 days before or after). All participants will be followed up for 12 months from inclusion in the study. Immunization is expected to reduce the risk of moderate to severe disease of those with comorbidities to the level of those of the same age group who do not have these comorbidities but face similar occupational risks.

This is a multicentre, open-label Phase 1/2 study, with a first-in-human (FIH) dose escalation part (Phase 1 study) followed by an open-label single arm (or two-arms, randomized) dose expansion part (Phase 2 study). The vaccine will be administered by intramuscular (IM) injection followed by electroporation (EP) applied to the injection site. The study is aimed at assessing the safety and immunogenicity of COVID-eVax, a DNA plasmid-based vaccine whose target antigen is a portion of the S protein of SARS-CoV-2 virus (the Receptor Binding Domain located in the CTD1 of the S1 region of the S protein). In animal models COVID-eVax was safe and induced high immunological humoral and cellular response.
COVID infection has resulted in multi-organ injury and may result in cardiovascular, pulmonary, neurological, and muscular damage. It is associated with significant asthenia and the long-term effects of the infection are still unclear, particularly for the development of pain and delayed functional rehabilitation. Glycomics "is the systematic study of the structure of glycans in a given cell type or organism. Glycans are complex oligosaccharides attached to proteins and lipids that regulate a variety of organic processes, including immunity Thus, glycans may influence different moments of the response to the virus and involved in the clinical severity of the disease, but may also change depending on the severity of symptoms and the organic response to SARS-CoV-2 infection. Glycomic data could provide important insights into interindividual differences at the molecular level that directly interact with SARS-CoV-2 and the development of mid- and long-term side effects. The ability to identify early those susceptible to developing COVID-19 infection and at higher risk for COVID-19 with unfavorable outcomes long after infection would help guide therapeutic strategy and provide important guidance for rational health care organization, which is of outmost importance. Long-term outcome data regarding post-COVID patient functional capacity and glycomics will be compared to assess whether there may be differences in protein glycosylation that may predict patient outcome.
The primary objective of this study is to evaluate the efficacy of the drug nitazoxanide 500 mg, administered three times a day, in relation to placebo in preventing the development of COVID-19 in household contacts of patients diagnosed with the disease.
Covid-19 is an important human and animal pathogen, it mostly causes respiratory and gastrointestinal symptoms. Clinical features range from a common cold to severe diseases such as severe acute respiratory distress syndrome, bronchitis, pneumonia, multi-organ failure, and even death. It seems to be less commonly affecting children and to cause fewer symptoms and less severe disease in this age group compared with adults. Clinicians have observed many extrapulmonary manifestations of COVID-19, as hematologic, cardiovascular, renal, gastrointestinal and hepatobiliary, endocrinologic, neurologic, ophthalmologic, and dermatologic systems can all be affected. This retrospective study that will be conducted at Hamad General Hospital in Qatar, aims to determine the renal involvement in all pediatric patients who were hospitalized with COVID-19 from March 1, 2020, to January 1, 2021.
The objective of the National Survey of Early Care and Education (NSECE) is to document the nation's current supply of early care and education (ECE) services. Because the COVID-19 pandemic is likely to have had an impact on the ECE supply, and because the availability of ECE services is critical to restoring the U.S. economy, updated data on the ECE supply will be crucial for policy-making and research. The purpose of the NSECE COVID-19 Follow-up Study is to describe the impact of the COVID-19 pandemic on the pre-pandemic ECE supply and the ECE workforce, including changes in supply or departures from and re-entries to the workforce. Data from the study can be used to estimate the impact of the pandemic on ECE supply and the financial health of ECE providers, as well as providers' experiences during and after the pandemic emergency. Through a two-wave design, the NSECE COVID-19 Follow-up Study data will trace providers' and workforce members' experiences from 2019, through the initial months of the pandemic (to be reported in the Wave 1 interview), and then to the one-year point since the onset of the pandemic (to be reported in the Wave 2 interview). This design is intended to capture the trajectories of providers and workforce members, for example through recovery back to full or modified participation in ECE supply, or long-term exits from ECE supply. Prospectively collecting these data allows inference about the types of providers and workforce members most likely to have exited or survived in ECE, as well as the programmatic supports received by those who remain in ECE at the time of the second interview.
