Filter by:The thyroid gland has been shown to be a common target for COVID 19 virus. Babies born to mothers positive for COVID 19 infections were noticed to have elevated thyroid stimulating hormone ( TSH ) levels on screening. Thyroid function tests were monitored in these babies to determine presence of temporary or permanent thyroid disorders following COVID 19 infections during pregnancy.
Novel coronavirus disease (COVID-19), caused by Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus, was first reported in December 2019 in Wuhan, China. The disease has spread to many countries in a few weeks and has become a global public health problem. By 2022, the virus has infected more than 500 million people worldwide and caused more than 6 million deaths. Case fatality rates (CFR) are an important index that helps to understand the epidemiological characteristics of an epidemic. In the data coming in 2020, COVID-19 CFR values were generally reported in the range of 0.001-0.706. However, from 2019 to 2022, there were 2 major changes that could affect the CFR of the disease. The first of these is vaccine applications, and the second is the new variants of SARS-CoV-2, which appeared first. From 2019 to 2022, it is likely that there will be a change in the mortality of COVID-19 in relation to both the vaccines administered and the new variants emerging. However, the data on this subject are not clear yet and more studies are needed. The aim of this study is to determine whether there is a change in the mortality of COVID-19 from 2019, when it first appeared, to 2022.
Under protocol versions 1.01-1.06: The five recently emerged SARS-CoV2 variants that were designated as VOCs are the Alpha variant, Beta variant, Gamma variant, Delta variant and the Omicron variant. The current dominant Omicron variant was designated a VOC by WHO on Nov 26, 2021, and was found to comprise 85% of reported variants in late January 2022. Studies have shown that the prevalent Omicron mutations in the S1 subunit RBD region and NTD region could dramatically change the antigenic features of the viral spike, leading to significantly reduced neutralization Omicron harbors 30 signature mutations (>50% prevalence) of which 15 are in the S1 subunit RBD region and 8 are in the S1 subunit NTD region. Omicron is a highly contagious variant with threatening immune evasion capabilities even despite robust immune response. Initial modeling showed the Omicron variant being 2.8 times more infectious than the Delta variant. While current vaccines are losing protection against Omicron with respect to infection and mild disease, there is still considerable protection from hospitalisation and severe COVID-19, especially after a booster dose. The International Coalition of Medicines Regulatory Authorities (ICMRA) COVID-19 Omicron Variant Workshop encouraged the international scientific community and vaccine developers to look at alternative approaches to monovalent vaccines. In ICMRA's view, companies should also explore the feasibility of developing bivalent or multivalent variant vaccines to determine if they offer advantages to monovalent vaccines. As advised by ICMRA, the investigated vaccine, mRNA-1273.214 is a bivalent vaccine containing the ancestral SARS-CoV-2 and the Omicron variant spike sequences that will be evaluated as a heterologous boost. Under protocol version 1.07:The study will also investigate the safety, reactogenicity and immune response of the mRNA-1273.222 administered as a boost vaccine after primary series vaccination comprising 3 doses of an mRNA vaccine . This study hypothesizes that the peak level of antibodies against SARS CoV-2, will be at two weeks after the first study dose is administered, which is similar to other recent findings (Anderson et al., 2022).2.2.1. The bivalent mRNA-1273.222 vaccine contains mRNA encoding for the spike protein of BA.4/BA.5 as well as mRNA encoding for the original (ancestral Wuhan-Hu-1) strain of the SARS-CoV-2 virus.
Integration of antigen-detecting rapid diagnostic tests (Ag-RDT) for COVID-19 into services that provide care for vulnerable populations such as pregnant women, children, people with HIV infection, and patients with tuberculosis (TB) will identify more people with Coronavirus infection. This will allow for earlier treatment and tracing of contacts to decrease the spread of the coronavirus. This study is looking at two models for providing the testing in Maternal, Newborn and Child Health (MNCH), Tuberculosis (TB) and HIV clinics in Cameroon and Kenya. In some clinics, attendees with be screened for Coronavirus symptoms and history of exposure and if positive they will receive the rapid coronavirus test right in the clinic. In other facilities, all people attending the clinic with be provided with the coronavirus testing even if they screen negative to see how many people are infected but do not show any symptoms. Hospitalized and non-hospitalized patients with the coronavirus infection will be followed to document their illness and health outcomes. We will also ask health care workers about how well the testing in these clinics is working and what are some of their challenges, and collect information about the costs associated with both the models of testing.
The coronavirus disease 2019 (COVID-19) is a highly contagious disorder caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). COVID-19 is a multisystem disease and therefore presents a variety of symptoms in the acute phase, such as fever, dry cough, fatigue, sore throat, loss of taste or smell, shortness of breath, nasal congestion, chest pain, muscle or joint pain, headache, and nausea. COVID-19 primarily affects the respiratory functions of individuals. Although this situation is more difficult in hospitalized patients, it also causes severe effects in individuals who recover with home medication. It is thought that this damage caused by COVID-19 may cause permanent effects on individuals in the long term. During the COVID-19 period, individuals also had to maintain an inactive lifestyle due to quarantine. This decrease in physical activity capacity also causes permanent damage to the respiratory functions of individuals. In addition, studies have focused on this population, as COVID-19 usually affects older individuals. However, considering that young people are also exposed to the COVID-19 virus, the effect on respiratory functions in these individuals should also be examined. Combined with the available information on pulmonary functions, there is insufficient evidence about extrapulmonary features in post-COVID-19 patients who survive mild illness in the long term. It is also necessary to examine whether there is permanent damage to extrapulmonary features such as peripheral muscle strength in these individuals. Therefore, in our study, it is aimed to examine the long-term results of respiratory functions, respiratory muscle strength and peripheral muscle strength of young individuals who recovered from COVID-19 and recovered from mild disease.
Most people who have coronavirus disease (COVID-19) recover completely without any sequelae. However, some patients continue to experience symptoms of COVID-19 even though their tests turn negative. This clinical spectrum that occurs after acute infection is called the post-COVID syndrome (PCS). Dyspnea, pain, decreased exercise capacity, limitations in activities of daily living, poor sleep quality, anxiety and depression are common symptoms in PCS. The aim of our study is to examine the effect of tele-rehabilitation-based exercise program on dyspnea, pain, functional capacity, sleep quality, anxiety and depression in individuals with PCS.
Open label clinical trial of persons (adults) that will determine the safety and efficacy of the diet supplement oral mitoquinone/mitoquinol mesylate (Mito-MES) to prevent the development and progression of severe viral infections like COVID-19 after high-risk exposure to a person with possible respiratory viral infection such as SARS-CoV-2 infection in persons who will receive Mito-MES compared to persons who will not receive Mito-MES (controls).
This is a randomized, double-blind, active-controlled Phase Ⅲ clinical trial, as well as an immuno-bridging clinical trial by parallel testing previous serum after primary immunization of COVID-19 vaccine (Vero cell), inactivated (Omicron variant). The main purpose of this study is to evaluate the superiority of immunogenicity against SARS-CoV-2 Omicron strain induced by one-dose booster immunization of inactivated COVID-19 vaccine (Omicron variant), developed by Sinovac Research and Development Co., Ltd.in subjects who have received two- or three-dose Prototype COVID-19 vaccine （CZ strain）, compared with one-dose booster of Prototype COVID-19 vaccine （CZ strain） in subjects who have received three-dose Prototype COVID-19 vaccine （CZ strain）, and to evaluate the non-inferiority of immunogenicity against SARS-CoV-2 Omicron strain induced by one-dose booster immunization of inactivated COVID-19 vaccine (Omicron variant), developed by Sinovac Research and Development Co., Ltd., in subjects who have received two- or three-dose Prototype COVID-19 vaccine, compared with the immunogenicity against SARS-CoV-2 Prototype strain induced by two-dose Prototype COVID-19 vaccine（CZ strain）after primary immunization.
Socio-demographic factors in relation to the diagnosis of COVID cases are increasingly mentioned in the role of transmission, but unfortunately with a small number of conclusive publications on French data. Our objective is to analyse the distribution of cases according to these factors and their possible role during the first 6 weeks of 2021 when the Alpes Maritimes was the department with the highest incidence rate. The collaboration between ARS06 and the Public Health Department in the field of COVID-19 has made it possible to have a departmental bulletin for monitoring the evolution of the epidemic (incidence, screening, hospitalisation). Knowledge of the socio-demographic, meteorological and environmental factors associated with the transmission of SARS-CoV2 would make it possible to reflect on how to act on these factors and to implement a public health policy.
The aim of this study is to determine what impact the COVID-19 pandemic may have had on the choices of high school students to pursue medicine as a career.
