Active clinical trials for "Severe Acute Respiratory Syndrome"

This QI project seeks to evaluate the relative test sample acquisition throughput, personal protective equipment utilization, and relative operational costs of provider-administered COVID-19 (SARS-CoV-2) nasal samples with and with the use of HEPA-filtered, positive pressure isolation booths.

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.

This is an expanded access program providing COVID-19 convalescent plasma to patients hospitalized with severely or life-threateningly ill COVID-19.

As dentists begin reopening their practices during a global pandemic, the risk of COVID-19 infection that dentists 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. The goal of the proposed study is to understand U.S.-based dentists' health and dental-practice reactions to COVID-19. To estimate this, U.S-based dentists will be surveyed monthly. These findings could be used to describe the prevalence and incidence of COVID-19 among dentists, determine what infection control steps dentists take over time, and estimate whether infection control adherence in dental practice is related to COVID-19 incidence.

Background. The current coronavirus disease (COVID-19) has a great impact worldwide. Healthcare workers play an essential role and are one of the most exposed groups.Information about the psychosocial impact on healthcare workers is limited. Methods. 3109 healthcare workers completed a national, internet-based, cross-sectional 45-item survey between 9 and 19 April 2020. The objective is to assess the psychological impact of the COVID-19 pandemic in Spanish healthcare workers. A Psychological Stress and Adaptation at work Score (PSAS) was defined combining four modified versions of validated psychological assessment tests (A) Healthcare Stressful Test, (B) Coping Strategies Inventory,(C) Font-Roja Questionnaire and (D) Trait Meta-Mood Scale.

Emerging in China in December 2019, Covid-19, whose pathogen is SARS-Cov-2, was declared a global pandemic in March 2020. The clinical presentation is highly variable, ranging from asymptomatic forms to acute respiratory distress and even death. Transmission is by droplet route, with an R0 of approximately 3. Rapidly, population protection measures were put in place by governments, including the confinement of all persons whose functions were not considered essential and the closure of educational institutions. Health care institutions are places at risk of Covid-19 transmission and hospital staff are particularly exposed, either through direct contact with patients, contact with exposed persons or through the environment. In order to protect personnel, hygiene measures were immediately recalled and reinforced. During the period of containment, the majority of students from the Lyon-Bron Military Medical Schools were sent as reinforcement in Army Training Hospitals and in the Military Reanimation Unit (Mulhouse). Some students developed symptomatic forms of SARS-Cov-2 infection, documented by positive PCR, during Operation Resilience or on their return from the mission. The Lyon-Bron Military Medical Schools staff, exposed both to the initial phase of the epidemic and to national protection measures, represent an extremely interesting population for understanding the epidemiological dynamics of the virus.

There are several clinical presentations of SARS-CoV-2 infection. Among the severe forms, pulmonary involvement with respiratory failure is common. Although severe lung involvement with SARS-CoV-2 meets the Berlin criteria for Acute Respiratory Distress Syndrome (ARDS), it differs from classic ARDS in that compliance (reflecting distensibility of the lung parenchyma) is frequently preserved. If the interest of Electrical Impedance Tomography has been demonstrated in classical ARDS, this is not the case in ARDS with COVID-19. However, the use of this technique in this particular patient population would make it possible to distinguish patients with severe hypoxemia linked to derecruitment from those without derecruitment, in whom hypoxemia is more likely to be linked to the loss of hypoxic vasoconstriction.

The investigators aim to carry out a retrospective observational study, analysing lung ultrasound images from patients who have presented to A&E for routine diagnostic purposes (ruling out cardiogenic pulmonary oedema, Pulmonary embolism and pericardial effusions) and systematically assessing for abnormalities typical for COVID-19 infection (Pleural irregularities, B lines, consolidations, pleural effusions). Doing this, the investigators will also develop a suggestion for a standardised technique for lung ultrasound which can be transferred to other clinical settings (Intensive Care, Acute medical Unit) and could form the basis for an international standard. Thirdly, the investigators aim to correlate our findings to clinical severity judged by oxygenation status on arrival in ED. To the investigators' knowledge, this is the first study of this kind.

This treatment protocol is designed to provide convalescent plasma as a therapeutic option for patients diagnosed with and hospitalized for COVID-19 with symptoms ranging from mild to life-threatening.

On January 2020, the discovery of a new coronavirus (SARS-CoV-2) was officially announced by the Chinese health authorities and the World Health Organization (WHO). Its complete genome was sequenced by the laboratory of respiratory infection viruses at the Institut Pasteur on 29 January 2020 in France. This will allow the identification of antigenic structures involved in the immune response and the development of serological diagnostic tests. Many questions are being asked about this new virus and the infection it causes, including questions about the percentage of asymptomatic and pauci-symptomatic forms. Serological studies can provide answers to these questions. There is no serological test for SARS-COV-2 yet, but the laboratory of respiratory infection viruses at the Institut Pasteur is working on its development. This study proposes to carry out a collection of samples taken from subjects who travelled to China before the epidemic outbreak or suspected of being infected with SARS-CoV-2. As soon as it is available, serology will be performed on the collected samples.
