Filter by:One of the major problems in suppressing the spreading of an epidemic resides in understanding and monitoring its propagation patterns, and in evaluating how these are modified by enforced policies. The standard solution requires detailed information at the microscopic scales, e.g. how infected people have moved and whom they came in contact with, which is hardly ever available. The researchers propose a novel approach to the study of the propagation of COVID-19, in which a proxy of this information is derived at macroscopic scales. This will be based on two ingredients: the spatiotemporal study in shiny with mathematical models with aggregated or non aggregated data and the reconstruction of functional networks of spreading patterns, and the development of a supporting software.
This is a study of validation for diagnostic techniques used on epidemiological control in the COVID-19 pandemic. It will be carried out in accredited public, private and university clinical laboratories of the collaborator institutions of the project based in Tarija, Bolivia. It is designed as a sectional validation study, using samples from specific groups of participants from the municipality of Tarija grouped according to their category with respect to symptoms and viral load of COVID-19. The sample is selected for convenience.
This is a prospective, multisite, descriptive, observational clinical/epidemiological study examining both quantitative and qualitative data pertaining to clinical outcomes and organizational responses to the 2020 SARS-Coronavirus-2 (SARS-CoV-2) pandemic.
COVID-19 had a major impact on dermatology practice globally with special emphasis on chronic diseases e.g. psoriasis. The main objective of this work is to investigate the effect of COVID-19 pandemic on psoriasis management. This work is designed as a cross-sectional survey based on a questionnaire directed to Egyptian dermatologists.
This is a pilot study to assess whether artificial intelligence (AI) combined with continuous vital signs monitoring from wearable sensors can predict clinically relevant outcomes in patients with suspected or confirmed Covid-19 infection on general medical wards.
In December 2019, a cluster of pneumonia cases of unidentified cause emerged in Wuhan,was identified as the culprit of this disease currently being identified as "Coronavirus Disease 2019" (COVID-19) by World Health Organization. Coronavirus was found to not only target the patient's lungs but also multiple organs. Around 2-33% of Coronavirus Disease-19 patients developed gastrointestinal symptoms. Studies have shown that Severe acute respiratory syndrome coronavirus 2 (SAR-CoV-2) was found in patient's feces, suggesting that the virus can spread through feces. In our previous study, stool samples from 15 patients with COVID-19 were analysed. Depleted symbionts and gut dysbiosis were noted even after patients were detected negative of SARS-CoV-2. A series of microbiota were correlated inversely with the disease severity and virus load. Gut microbiota could play a role in modulating host immune response and potentially influence disease severity and outcomes. The investigators are uncertain about the impact of synbiotic on patients with COVID-19. However, a therapeutic strategy aiming at investigating the gut Imicrobiota of patients with COVID-9 who take synbiotic or not, leading to lesser progression to severe disease, less hospital stay and improved quality of life.
CORONAVIT is an open-label, phase 3, randomised clinical trial testing whether implementation of a test-and-treat approach to correction of sub-optimal vitamin D status results in reduced risk and/or severity of COVID-19 and other acute respiratory infections.
An observational cross sectional questionnaire study looking into facial hair of hospital doctors during the COVID-19 pandemic, and how personal protective equipment guidance has affected this.
The purpose of this research study is to determine if high-frequency, rapid turn-around SARS-CoV-2 surveillance testing with this assay is feasible and able to be optimized to enable isolation and follow-up diagnostic testing. This test will be performed at various locations in the Madison, Wisconsin 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. Up to 10000 participants will be recruited for this study.
This project will provide novel data using a large cohort of more than 3000 transplanted patients. Risk and protective factors for SARS-CoV-2 infection and COVID-19 disease severity will be identified. The proportion of patients who develop antibodies after infection will be revealed. In this way the presence of these antibodies can be evaluated as a test for prior infection. Our study additionally will demonstrate how long these antibodies remain present and whether they are protective against a new infection.
