Active clinical trials for "COVID-19"

We are trying to see whether a self-collected saliva swab in the home setting is as good as or better than a study clinician-collected anterior nose swab in evaluating whether you are positive for COVID-19 or Influenza A/Influenza B. You may have no symptoms, so you may be positive and capable of spreading the infection to others and you don't know it. Knowing whether you are positive is important because you would have to quarantine and not go out to prevent spreading the infection to others.

Purpose: to develop an international validated patient-reported outcome measure for COVID-19 patients according to international guidelines. In this phase III of the project, the preliminary questionnaire of 80 items will be tested. It has been developed based on literature review and interviews with health care professionals and patients (phase I-II). In Phase III A patients will fill in the questionnaire followed by interviews on relevance, importance and wording of the questionnaire In Phase III B patients will fill in the questionnaire and an debriefing questionnaire. We will do explorative psychometric analyses.

This is a case series of patients with COVID-19 admitted to the northeast Brazil region, in a referenced hospital for COVID-19, during the 2020 COVID-19 pandemic. Data will be collected prospectively and retrospectively. The main objective is to describe the characteristics of critically ill patients with COVID-19 and their clinical outcomes, and to identify risk factors associated with survival, to guide the strategy to mitigate the epidemic, both within each hospital and ICU and in public health management.

An observational study of patients with COVID-19 confirmed cases (with various degrees of severity) and controls. Oral and nasal swabs will be taken from 150 patients (50 with mild form and 50 with severe form of COVID-19 with or without mechanical ventilation, 50 healthy controls).

The coronavirus disease 2019 (COVID-19) pandemic represents a major threat to global health. Since the beginning of the COVID-19 epidemic, all eyes have been focused on the significant somatic complications of COVID-19, but the impact on behaviors, particularly those that can lead to addictive disorders, remains little studied. A set of factors could explain a change in gambling activities, both in number of gamblers and in intensity of practices, due to the pandemic. On the one hand, the reduction or even the interruption of sporting and horse racing competitions may induce a decrease in these activities (both online and offline). Moreover, the closure of certain gambling venues and travel restrictions may also lead to a decrease of offline gambling activities in general. On the other hand, gamblers who can no longer perform their usual gambling activity could refer to available online gambling activities (poker, lotteries, casinos, etc.). Moreover, the threat of a financial crisis, the negative impact on psychological well-being (due to social isolation, stress of being infected, etc.), and increased time spent freely online, could also very largely motivate an initiation or an exacerbation of the gambling activity, especially online and in people in a situation of vulnerability. Both in France and Sweden, the closing of sports and horse race events has led to a sharp decrease in sports and horse-race betting. In both countries, the increase in other gambling types, including illegal gambling, and their potential for gambling problems is a source of concerns for public health authorities. As a consequence, more research is promptly needed in this area. The use of gambling tracking data, widely acclaimed in recent years in research on online gambling given its ecological nature, could allow observing longitudinally changes in online gambling practices (both the raw gambling activity and risky behaviors) and in the use of responsible gambling (RG) tools due to the pandemic. Moreover, the combination of French and Swedish data will allow comparing two countries with very distinct politics regarding the pandemics, i.e. a lockdown in France in March - May 2020 and then in November - December 2020 compared to no lockdown in Sweden. Finally, gambling in women is on the rise and women display specific gambling behaviors, especially in early stages of the online gambling practice. The project will include the investigation of gender specificities both in the investigation of the impacts of the pandemic and in the comparison of French and Sweden gambling behaviors. Age, type of gambling activity and country (France / Sweden) will also be taken into account.

Our primary aim is to collect breath samples from COVID-19 positive patients at the time of diagnosis, during and after recovery using the same patient as his/her own control to identify VOCs specific to SARS-COV-2 viral infection. A secondary aim is to determine the patient's likely disease trajectory in terms of recovery versus progression to respiratory and or multi-organ failure. Breath samples will be collected as soon as the patient is admitted to the Vancouver General Hospital COVID Ward with a diagnosis of COVID-19 by RT-PCR in nasopharyngeal/throat swab. A second breath sample will be obtained one week later, or before hospital discharge or if they become sicker prior to transfer to the intensive care. A third sample will be taken to 8-12 weeks after recovery from the illness with a negative COVID-19 RT-PCR test. VOCs in exhaled breath will be measured by gas chromatography-mass spectrometry (GC-TOF-MS or GCxGC-TOFMS). VOC profiles from the symptomatic phase and recovery phase will be compared to determine if there are unique VOCs associated with COVID-19 infection. Comparison of VOC profiles between those who recover and those who progressed will provide information on potential prognostic features. The results of this pilot study will form the basis to determine if a larger study is warranted.

During this exceptional health crisis, this study of the current care of a neurosurgical activity, which is essential in a University Hospital Centre, will enable us to better understand how we function, the response given to a population with the means at our disposal, the implementation of new therapeutic strategies and their limits, ethical reflection, and, how to pursue a distributive and quality medicine. The restriction of conventional medical resources to our care activity (resuscitation, personnel, operating theatre, constraints linked to the risk of contamination...) is leading to a new medical organisation imposing new Covid-19 standards, the description of which seems essential to us. A knowledge of the strategies to be adopted during a disaster health situation in order to continue providing care to the civilian population. How can we prevent the setting up of health care systems outside the cause of the health crisis? n triage medicine, Avoiding the "burn-out" of doctors struck by the health crisis.

In this study, investigators try to estimate Covid-19 Cases and Deaths using countrywide annual macro-scale indicators (i.e., estimators) such as non-communicable disease data from WHO (who. int), social and economical indicators from UN (un.org) and Worldbank (worldbank.org), and Covid-19 Cases and Deaths from Worldometer (https://www.worldometers.info).

COVID-19 infection manifests in its severe form as acute alveolo-interstitial and vascular pneumonitis. However, long-term outcome remains unknown. A progression to fibrosing pneumonia could affect 10 to 30% of survivors of severe forms, making it a public health problem through secondary disability. The project concerns the analysis of CT images of patients followed at the Avicenne APHP hospital (Bobigny) in collaboration with two expert image treatment/modelling teams for an evaluation of vascular remodelling and mechanical simulation of the regional lung compliance. These parameters obtained at 2-4 months of COVID-19 infection will be correlated with clinical, CT, and functional data at 6 months and 1 year follow-up. This project should make it possible to understand the COVID-19 infection manifests as an acute alveolo-interstitial and vascular pneumonitis in its severe form. However, long-term outcome remains unknown. It has been hypothesized that a progression to fibrosing pneumonia could affect 10 to 30% of survivors of severe forms, making it a public health problem through secondary disability. But there is no parameter which could currently allow to predict such an outcome. The SILICOVILUNG project is based on the CT images analysis of patients followed at the Avicenne APHP hospital (Bobigny, France) after severe COVID pneumonitis in collaboration with two expert image treatment/modelling teams [ Artemis Telecom Sud-Paris (Evry, France) and LMS INRIA Ecole Polytechnique (Palaiseau, France)] for an evaluation of vascular remodeling and mechanical simulation of the regional lung compliance using a poromechanical model. These parameters obtained at 2-4 months of COVID-19 infection will be correlated with clinical, CT, and functional data at 6 months and 1-year follow-up. This project should make it possible to understand the mechanisms of regional physiology in the evolution of COVID-19 pneumonias in their severe forms and to anticipate the development or not of sequelae, particularly fibrosing.

BACKGROUND COVID-19 response is heavily impacting the availability of essential health services, especially services for pregnant women and newborns that cannot be delayed or rapidly reorganized in other settings. In the current pandemic, due to multiple factors access to high quality and timely maternal and newborn (MN) health care is threatened. Major concerns have also been raised with respect to maternal rights and on disruption of essential practices and increased medicalization of care, despite existing WHO guidance. Based on preliminary reports heterogeneities in practices is expected within the WHO European Region, with major inequities (eg women experiencing disruption of essential MC health services only in selected countries or areas within the countries, while having access to adequate care in others). With IMAgiNE EURO we aim at conducting a survey to explore the health service preparedness, quality and resilience, with a specific focus on health services around the time of childbirth, in the WHO European Region during COVID-19 pandemic, and to make available data, which, in collaboration with WHO and other partners, can contribute in improving the quality of MN health care. HYPHOTESIS AND SIGNIFICANCE This project has been developed in coordination with WHO Regional Office for Europe (EURO) and other partners, and ultimately aims at making available and disseminate data that can help improving the quality of MN health services in the Region. Collecting data on the quality of essential MN health services across different countries within the WHO European Region will help addressing specific gaps and planning coordinate response to improve quality of MN care and improve MN health outcomes. The project will also offer the opportunity to develop tools and methods to monitor the quality of MN health care across different countries and settings. The project will establish and consolidate a research network Primary objective: 1. Record, analyse, and describe data on MN health service preparedness, quality and resilience - with a specific focus around the time of childbirth as measured both from health workers and women perspectives- across different countries within the WHO European Region, during COVID-19 pandemic. Secondary objectives: 2.Develop tools and methods to measure, through rapid online surveys, the quality of MN health care across different countries and settings 3.Establish and consolidate a research network
