Filter by:Coronavirus Disease 2019 (COVID-19) is a disease caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) virus. It was first isolated in Wuhan, China in December 2019 and then rapidly spread to the rest of the world posing a severe threat to global health. Many therapeutics have been investigated for the treatment of this disease with inconclusive outcomes. Protease inhibitors are one of the proposed agents, but their use is limited to their significant drug interactions and side effects. The aim of this study is to compare the efficacy and safety outcomes of Darunavir/Cobicistat versus Lopinavir /Ritonavir in the treatment of patients with COVID-19 pneumonia in Qatar.
Recently, the world was shaken awake by a pandemic caused by a novel coronavirus SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2). In most nations drastic isolation measures were taken to minimize the further spread of the Coronavirus Disease 2019 (COVID-19). Being the first pandemic sparked by a Coronavirus, little was known on COVID-19 and its implications on general health. Our understanding on the virus and its potential effects on health is growing. In Belgium, the situation is stabilizing, and doctors and healthcare workers are slowly recommencing routine work and consultations. As also fertility treatments were abruptly interrupted, many patients are in need to resume their treatment. The limited evidence of SARS-CoV-2 on pregnancy seems to be rather satisfying1, but practically nothing is known about the possible impact of an active SARS-CoV-2 infection on female gametes. Viral transmission occurs predominantly through respiratory droplets, but transmission to gametes cannot be ruled out. Since the onset of the pandemic, knowledge about the molecular details of SARS-CoV-2 infection rapidly grew. Coronaviruses are enveloped RNA viruses. For a virus to deliver their genome into the host cell, attachment and entrance into that cell is a crucial step. The coronavirus surface protein spike (S) mediates entry into target cells by binding to a cellular receptor and subsequent fusing of the viral envelope with a host cell membrane. The SARS-CoV-2-S protein (SARS-S) utilizes angiotensin-converting enzyme 2 (ACE2) as a receptor for host cell entry. Host proteases such as transmembrane serine protease 2 (TMPRSS2) are then needed to cleave the viral S protein, allow-ing permanent fusion of the viral and host cell membranes2. Expression of ACE2 and TMPRSS2 has been shown in testicular, uterine and placental cells. Based on available transcriptomic data, co-expression of ACE2 and TMPRSS2 is also seen on oocyte level, but the possible impact on reproduction is unknown. The BSG (basigin or CD147), a receptor on host cells, was also identified as a possible route for viral invasion.
This will be a phase 1a randomized, open label, multi-center study with approximately 24 subjects. All subjects will receive standard of care (SOC) per institutional guidelines for treatment of hospitalized patients with COVID-19 infection. In addition to SOC, the brequinar group will receive 5 daily doses of brequinar 100 mg.
Disproportionate impact of COVID-19 in patients with obesity is now well established. Obesity is associated with severe forms of COVID-19 and may be a risk factor of intensive care unit (ICU) admission. Obesity is associated with COVID-19 related hospital death in a large United Kingdom cohort study. However, there is a gap of knowledge on assessment of outcomes such as severity of Acute Respiratory Distress syndrome (ARDS), duration of hospitalisation and mortality in ICU. Moreover, an obesity survival paradox has been observed in patients with ARDS. This raises the question whether the obesity paradox has been broken by COVID-19. The investigators aim to explore risk factors of in-ICU death for patient with COVID-19, including obesity and other chronic diseases and to describe the clinical course and outcomes, including the management of acute respiratory failure and other intensive care management.
The objectives of this study are to test the level of accuracy of the prediction models that could be used as a 'digital test' to evaluate whether an individual is infected with COVID-19, based on their symptoms reported in the "AiM COVID-19" app
The purpose of the questionnaire is to find risk factors for the development of post-traumatic stress disease (PTSD) in health workers during COVID-19 pandemy.
Background: Nasopharyngeal (NP) swabbing is being used to test for SARS-CoV-2 infection. For this, a swab is inserted deep into the back of the nose to collect a sample. It can cause discomfort for most people. Researchers want to find an easier way to collect samples. Objective: To learn if testing for SARSCoV-2 with a saliva sample only, a nasal swab from just the front part of the nostril only, or a saliva sample plus a nasal swab gives results that are as accurate as the NP swab. Eligibility: NIH staff members age 18 and older who are taking part in NIH CC SARS-CoV-2 surveillance. Design: The Occupational Medical Service (OMS) collects NP swabs as part of standard NIH staff screening. Participants will give 1 or 2 saliva samples and 1 or 2 nasal swabs when their NP swab is collected by OMS. If their NP swab was already collected, their OMS record will be reviewed for the result. If the NP swab result is positive, the participant will have another NP swab. At that time, they will also give 1 or 2 saliva samples and 1 or 2 nasal swabs. If the NP swab result is negative, they will give 1 or 2 saliva samples and 1 or 2 nasal swabs the next time they have an NP swab. For the saliva sample, participants will spit into a tube. For the nasal swab, the inside of the front part of the nostril will be swabbed. Participation ends after the study samples are collected. Participants can choose to keep giving saliva and nasal swab samples each time they have an NP swab.
The medical and paramedical staff of the front-line services are potentially exposed to SARS-CoV-2. Therefore, despite the application of standard protective measures, it is possible that a certain number of these personnel have already contracted SARS-CoV-2, including in its asymptomatic form. Serological testing in this context would be useful for deploying immune healthcare workers as to limit the risk of viral infection and transmission. Therefore, it is of utmost importance to prove that the serological response entails the production of neutralizing antibodies.
The objectives of this research is to: - Assess perceptions, concerns, and practices related to the COVID-19 pandemic and mitigation strategies using the MURDOCK Study Community Registry and Biorepository population as a measure of these features in Cabarrus County through a biweekly electronic survey. - Estimate the prevalence and change in prevalence of COVID-19 infection based on responses to questionnaire items on symptoms and practices using a biweekly electronic survey. - Among respondents to the baseline questionnaire, conduct at home mid-turbinate nasal swab collection for viral PCR testing for active COVID-19 infection as an estimate of the prevalence of active infection in Cabarrus County. - Among respondents to the baseline questionnaire, conduct serologic testing for IgG antibodies to SARS-CoV-2 as an estimate of the prevalence of exposure and potential immunity to COVID-19.
The purpose of this study was to assess the performance of a machine learning algorithm which identifies patients for whom hydroxychloroquine treatment is associated with predicted survival.
