Filter by:A prospective and retrospective cohort study. The objective will to determine the frequency of COVID-19 in pregnant and postpartum women hospitalized with flu syndrome, to evaluate clinical and laboratory predictors of COVID-19 progression and to determine the factors associated with adverse maternal and perinatal outcomes in healthcare centers in two states of Northeast Brazil.The study will be conducted including pregnant and postpartum women with clinical or laboratorial diagnosis of COVID-19, admitted in six healthcare centers in the Northeast of Brazil. All pregnant and postpartum women with clinical and/or diagnosis of COVID-19, attended in prenatal care, in emergency (maternity triage), high-risk pregnancy ward, obstetric intensive care unit and rooming-in ward will be included. The data will be collected in specific forms. The exams will be carried out by trained professionals within each institution.
A novel coronavirus was identified in late 2019 in Wuhan, China On 11 February, The International Committee on Taxonomy of Viruses (ICTV) announced that the official classification of the new coronavirus (2019-nCoV) is called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The World Health Organization (WHO) announced on the same day that the official name of the disease caused by the virus is Corona Virus Disease-19 (COVID-19). WHO has declared the infection a Pandemic on March 11, 2020. Based on previous studies on SARS in 2003 and SARS-MERS 2013 there was a genetic polymorphism associated with the susceptibility and severity of the disease. Interleukin-12 (IL-12) is a cytokine secreted by activated phagocytes and dendritic cells. It plays a pivotal role in promoting Th1-type immune responses and cell-mediated immunity. IL-12 triggers many biological functions: it stimulates the proliferation of activated T- and NK-cells, enhances T- and NK-cell-mediated cytolytic activity, and induces the production of IFN-γ by both T-and NK-cells. The interferon-γ production induced by IL-12 forms a major link between innate and adaptive immunity. A recent study revealed that interferon-mediated immunopathological events are associated with atypical innate and adaptive immune responses in SARS patients. Also, TNF-α is a key mediator of the inflammatory response and is critical for host defense against a wide variety of pathogenic microbes. However, the over-expression of this cytokine may lead to badness in disease recovery. The dual role of TNF, acting as an agent of both innate immunity and inflammatory pathology, poses a considerable challenge for gene regulation.
Assessment of the clinical effects of infusions of cryopreserved allogeneic multipotent mesenchymal stem cells of the placenta and umbilical cord for COVID-19 patients with acute respiratory distress syndrome.
In Mexico the total number of confirmed cases of COVID-19 is 232, 000 and 28,510 deaths. Health workers are at high risk of COVID-19 infection. Their absence from work dramatically limits the ability to contain the disease. There is currently no vaccine to prevent the disease. Since the introduction to the vaccination schedule of the Bacillus Calmette-Guerin (BCG) live attenuated vaccine directed towards tuberculosis prevention, a decrease in infant mortality has been reported, not related only to tuberculosis. BCG vaccine has been hypothesized to have a non-specific role towards other unrelated pathogens such as viruses that cause airway disease, with reduced morbidity and mortality. In murine as well as in human models it has been shown to decrease the incidence of acute respiratory influenza infections. Likewise, in countries with a high endemicity for tuberculosis, the BCG vaccine reduces the incidence of respiratory infections by up to 80% . In healthy subjects, the BCG vaccine increases the production of proinflammatory cytokines in monocytes. Likewise, it increases the epigenetic response, causing an increase in the transcription of genes important in the antimicrobial response, as well as an improvement in cellular function. This is the first national clinical trial to evaluate prospectively the effect that the BCG vaccine offers towards the prevention and reduction of severity in cases of COVID-19.
This research is planned to illustrate the efficacy and safety of sirolimus as an adjuvant agent to the standard treatment protocol against COVID-19 infection
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).
On 11th of March 2020, WHO characterized COVID-19 infection as a Pandemic. After the COVID-19 infection is declared as a Pandemic there was an outburst regarding COVID-19 Research. The Research interest led to registration of Interventional and Observational studies world wide. There are constant efforts by Health care workers to seek information regarding the Interventional and Observational studies which can help in decision making regarding effective handling of COVID-19 infected patients. It is also important to track on the happenings in various frontiers of COVID-19 Research in view of historical interest and clinical relevance. This Observational Cross sectional study aims to explore the completed Researches in WHO-compliant registries to understand the trends of COVID-19 Research. This study aims to get a birds eye view of ongoing COVID-19 Research scenario worldwide. This study results can directly benefit the worldwide Academicians and Health Care Professionals to understand the ongoing COVID-19 Research trends.
