Filter by:The overall goal of this study is to understand the immune response (IgG) to SARS-CoV-2 to fill critical knowledge gaps in the natural history of this virus and to inform the development of future infection mitigation efforts. The study team aims to assess the prevalence of circulating IgG antibodies to SARS-CoV-2 and the factors associated with sero-prevalence. These data will be used to estimate the total population that has been exposed to the virus (asymptomatic and symptomatic), the proportion of the population that may be protected by natural immunity, and the proportion that is susceptible. Data obtained from this research will be shared with the Florida Department of Health.
There is an urgent need to evaluate effective treatments for COVID-19 patients. Melatonin has significant anti-inflammatory and antioxidant properties and it lacks of side-effects. This randomized controlled trial seeks to evaluate the efficacy of intravenous melatonin in reducing mortality in Covid-19 patients in the ICUs.
The purpose of this study is to determine if there may be COVID-19 virus in various samples collected from mothers and infants.
As dental practices reopen their practices during a global pandemic, the risk of 2019 novel coronavirus (COVID-19) infection that dental hygienists face in providing dental care remains unknown. Estimating the occupational risk of COVID-19, and producing evidence on the types of infection control practices and dental practices that may affect COVID-19 risk, is therefore imperative. These findings could be used to describe the prevalence and incidence of COVID-19 among dental hygienists, determine what infection control steps dental hygienists take over time, describe dental hygienists' employment during the COVID-19 pandemic, and estimate whether infection control adherence in dental practice is related to COVID-19 incidence.
Evaluating the smell and taste perceptions of patients hospitalized in the intensive care unit with suspicion of Coronavirus disease-19 diagnosis with a survey study
This pilot study is being performed to assess the efficacy and safety of inhaled ensifentrine delivered via pMDI compared with a matching placebo in conjunction with standard of care treatments on recovery in patients hospitalized due to COVID-19 infection.
While many people with COVID-19 suffer from respiratory disease, there is growing evidence that the virus also affects other organs. The purpose of this study is to better understand the effects of COVID-19 on the lungs and other organs. The study investigators have developed new techniques in Magnetic Resonance Imaging (MRI) to scan the lungs, heart, brain and liver. The study investigators hope to learn more about how the virus causes inflammation in these organs and how this inflammation changes over time as people recover from COVID-19 illness. The study aims to enroll 228 people in Alberta. Participants will undergo one or more MRI scans and have blood testing at one or more time points to assess for inflammation, kidney function, liver function and possible heart injury. Participants will also undergo testing to assess sense of smell, cognition (thinking and memory), spirometry (breathing test for lung function) and and exercise tolerance (walk test). The study investigators hope this study will help us learn more about the long-term risks of COVID-19 disease.
Clinical observation has found that COVID-19 patients often present inconsistency of clinical features, nucleic acid of the SARS-CoV-2 and imaging findings, which brings challenges to the management of patients.The quantitative assessment of patients' pulmonary lesions of chest CT, combined with the basic information, epidemiological history, clinical symptoms, basic diseases and other information of patients, will quickly establish a reliable prediction model for the severe COVID-19. This model will greatly contribute to the effective diagnosis and treatment of COVID-19.
Severe pneumoniae related to Coronavirus Disease (COVID-19), had a high in-hospital mortality; this condition are worst in subjects with acute kidney disease (AKI); conditioning increased mortality, days of assisted mechanical ventilation (AMV), increased nosocomial infections and high costs. We need many studies for determinated the risk factors for AKI in subjects with COVID-19. This study pretends identify the incidence of AKI in subjects with severe pneumoniae by COVID-19, describe the role of some biomarkers in the physiopathology of AKI-COVID-19; and determine the evolution of urinary biomarkers during hospitalization, like neutrophil gelatinase-associated lipocalin (NGAL), tissue inhibitor of metalloproteinases-2 (TIMP-2), insulin-like growth factor binding protein-7 (IGFBP7), and interleukin-6 (IL-6) and the progression of viruria of Severe Acute Respiratory Syndrome (SARS) related to CoronaVirus 2 (CoV2) in subjects with or without AKI.
Evaluating the rate of exposure to the virus in the close contact population who shared the home of a person infected with SARS-CoV-2 at the time of infection of the index case - adults or children - is a major factor in assessing the spread. virus in the family environment, assess the factors of circulation and determine whether immunity has been acquired. Screening for specific antibodies to SARS-CoV-2 will determine the exposure and protection acquired against this virus. Knowing the intra-family secondary transmission rate is essential for supporting the strategies for lifting the confinement envisaged and implementing a personalized approach. As of March 8, a platform for the home management of COVID + patients was set up when they, pauci or moderately symptomatic, do not require hospitalization. As of May 6, 2020, 881 patients have been registered in COVID and followed, constituting the active COVIDOM / PSL file. Of the 512 patients included between March 1 and 31, 45% have a household consisting of 3 people. All patients had weekly clinical follow-up by telephone for the duration of the disease with a maximum of 4 weeks having been achieved. If the recommendations of barrier gestures, isolation in an apartment were made during the symptomatic phase, the absence of masks available to all did not allow, in practice, to achieve the isolation and quarantine recommended ideally. to break the transmission of the virus. The FAMI-CoV study proposes to assess the rate of exposure to the virus in contacts sharing the same focus of index cases. A sub-study will assess the proportion of antibodies that have been neutralizing.
