Active clinical trials for "Coronavirus Infections"

Short description of the protocol intended for the lay public. Include a brief statement of the study hypothesis (Limit : 5000 characters) The management of critically-ill patients with organ failure due to COVID-19 represents a major healthcare burden. While endothelial inflammation has been reported in these patients, the pathophysiological mechanisms remain incompletely elucidated.

Medical context: Follow-up of a retrospective cohort of 499 cases of CoViD-19, hospitalized at the University Hospital of Reims during the health crisis, prospectively up to two years of follow-up. Possible intervention for serological monitoring, leading to a change from category 3 to category 2 (French law on human person research) Aim of the study: To know the factors of gravity of CoViD-19, to know its prognostic factors, to see how the evolution of the treatments implemented have influenced the fate of the patients. Material and methods: Type of study: cohort study Population: Patients in the CoViD-19 cohort - Reims Calendar: September 2020 - July 2022 Expected results: Better knowledge of the cares of patients with CoViD-19

The objective of this study is to compare psychological distress and needs of nurses in ICU before and during coronavirus pandemic.

Acute Respiratory Distress Syndrome (ARDS) is the main clinical presentation of SARS-CoV-2 (Covid-19) infected patients admitted in Intensive Care Unit (ICU). During the first phase of the outbreak (between February and May 2020), the use of invasive Mechanical Ventilation (MV) was largely required with 63% of ICU patients intubated in the first 24 hours after admission and up to 80% of patients during the overall ICU stay. Mortality was especially higher when using MV in the first 24 hours. In contrast, the use of non-invasive oxygenation strategies in the first 24 hours was only 19% for High Flow Nasal Cannula oxygen therapy (HFNC) and 6% for Non-Invasive Ventilation (NIV). Several non-invasive oxygenation strategies were proposed in order to delay or avoid MV in ICU patients suffering from Covid-19 ARDS. The use of HFNC became the recommended oxygenation strategy, based in particular on publications prior to the outbreak. The use of NIV or Continuous Positive Airway Pressure (CPAP) combined with HFNC have also been proposed. Although these non-invasive oxygenation strategies seem widely used in the second phase of the outbreak, they have not yet confirmed their clinical impact on MV requirement and patient's outcome. Moreover, no comparison has been made between these different non-invasive oxygenation strategies. The aim of this study is to compare different non-invasive oxygenation strategies (HFNC, NIV, CPAP) on MV requirement and outcome in ICU patients treated for ARDS related to Covid-19.

The investigators planned to examine a cohort of admitted patients at University of Chile Clinical Hospital with COVID-19 diagnosis. Authors report data on mortality, ICU admission, need of invasive mechanical ventilation, awake and ventilated prone positioning, use of High Flow Nasal Cannula, Thromboembolic disease, Acute Kidney Injury (AKI) and Renal Replacement Therapy. Additionally, the risk of in-hospital death according to chronic disease burden and severity of illness at admission was assessed.

Sedation of severe COVID-19 disease are often complicated. We try to find a correlate for this observation by encephalographic studies.

Covid-19 is an important human and animal pathogen, it mostly causes respiratory and gastrointestinal symptoms. Clinical features range from a common cold to severe diseases such as severe acute respiratory distress syndrome, bronchitis, pneumonia, multi-organ failure, and even death. It seems to be less commonly affecting children and to cause fewer symptoms and less severe disease in this age group compared with adults. Clinicians have observed many extrapulmonary manifestations of COVID-19, as hematologic, cardiovascular, renal, gastrointestinal and hepatobiliary, endocrinologic, neurologic, ophthalmologic, and dermatologic systems can all be affected. This retrospective study that will be conducted at Hamad General Hospital in Qatar, aims to determine the renal involvement in all pediatric patients who were hospitalized with COVID-19 from March 1, 2020, to January 1, 2021.

Over the last months, the Rizzoli Orthopedic Institute in Bologna, Italy, has drained orthopedic urgencies from all other hospitals in the urban and suburban area. In this context urgencies are defined as fractures and primary or metastatic bone lesions with indication to non-deferrable surgery. A subset of these patients tested positive for SARS CoV 2, either before or after the surgical procedure. Anesthesiological clinical management of covid19 cases is complicated by the consequences of the viral infection on respiratory and cardio-vascular systems, renal function and coagulation. Similarly, management of asymptomatic patients is challenging because of the lack of data on possible specific complications. This study will report a snapshot of our early experience on perioperative clinical management of patients undergoing orthopedic surgery in the presence of SARS CoV 2 infection, ascertained or not at the time of surgery.

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.

Between June 10t h and July 1st, a cross-sectional design study in an Argentina slum, showed a prevalence based on immunoglobuling G-class (IgG) antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) of 53.4%. It remains unanswered whether natural infection produces sustained antibodies. The aim of this study is to evaluate the presence of IgG antibodies for Coronavirus disease 2019 (COVID-19) after 5 months in inhabitants of Barrio 31 who consented the Seroprevalence Study for COVID-19.
