Active clinical trials for "COVID-19"

With the influx of patients suspected of Covid-19 and the limited number of hospital beds, there is a need for sensitive triage to detect patients at risk of pulmonary complications and therefore requiring hospitalization, but also specific triage to safely discharge patients without risk factors or signs of clinical or ultrasound severity. The use of pulmonary ultrasound in addition to clinical assessment seems appropriate. Indeed, it allows early detection of signs of pneumopathy which, in the current context, most often correspond to Covid-19. These signs include B-lines, which indicate interstitial pulmonary oedema, and an anfractuous and thickened pleural line, or even centimetric parenchymal condensations with a low level of pleural effusion. Conversely, the presence of a medium to large pleural effusion is not very suggestive of the diagnosis of Covid-19. In addition, a lung ultrasound score has been developed and validated to assess the severity of acute respiratory distress and predict the occurrence of acute respiratory distress syndrome. It is based on the performance of a 12-point (6 per hemi-thorax) pulmonary ultrasound with the collection of the presence of B-lines, condensation or pleural effusion. In the hands of a trained operator, this examination takes only a few minutes. The aim of the study is to develop a score based on clinical and ultrasound evidence to allow early and safer referral than that based on clinical evidence alone. To do this, the study will retrospectively collect clinical and lung ultrasound data from departments that use this technique on a daily basis.

During this pandemic period, the goal of the health care system is to optimize the use of intensive care services for patients infected with SARS-CoV-2, given the frequency of complications that can lead to high mortality. When patients with suspected or confirmed COVID-19 are admitted to hospital, whether or not they are symptomatic, there is currently no method to predict who will progress to complications requiring the use of intensive measures in 24-48 hours.

COVID-19 has a big impact on individuals and society as a whole. Especially persons with (multiple) comorbidities such as stroke are affected. The impact of COVID-19 on stroke rehabilitation delivery and stroke patients' functioning is unclear.

The understanding of haemostasis and inflammation cross-talk has gained considerable knowledge during the past decade in the field of arterial and venous thrombosis. Complex and delicately balanced interaction between coagulation and inflammation involve all cellular and humoral components. Elements of the coagulation system such as activated thrombin, fibrinogen or factor Xa may increase inflammation by promoting the production of pro-inflammatory cytokines, chemokines, growth factors and adhesion molecules that lead to a procoagulant state amplifying the pathological process. Recent evidence supports inflammation as a common pathogenic contributor to both arterial and venous thrombosis, giving rise to the concept of inflammation-induced thrombosis. Patients with infection of COVID-19 and severe pneumoniae seem to have higher risk of thromboembolism. Very few data are available regarding the biological disorders of coagulation in these patients. Th purpose of this project is to analyze hemostasis and coagulation of patients with infection of COVID-19 and severe pneumonia.

During COVID-19 epidemic, hydroxychloroquine was proposed and authorized as a possible key agent in the treatment of COVID-19 hospitalized pneumonia, including in France. Gautret et al. proposed the combination regimen with azithromycin. However only one study reported the interest of azithromycin alone. Retrospective study reporting the impact of the anti-infective agents used during the pandemic in a tertiary care hospital, using azithromycin with or without hydroxychloroquine.

Aim of the study is to investigate whether the Covid-19 is found in the vaginal swab samples of female patients diagnosed with covid-19, to evaluate the presence of Covid-19 and the risk of transmission of Covid-19 by intercourse or vaginal delivery.

This study seeks to determine how COVID-19 affects the clinical outcome of patients with chronic liver disease, and whether the clinical course of COVID-19 is influenced by underlying chronic liver disease.

Little is known about the physical function outcomes in patients with severe COVID-19 patients who are admitted to Intensive Care Unit (ICU) for invasive mechanical ventilation. The purpose of this study is to evaluate the short-term impact on physical function before hospital discharge in subjects with severe COVID-19 who have survived ICU admission for invasive mechanical ventilation.

The overall goal is to study the immune response to SARS-CoV-2 infection over the period of one year in the blood of a representative cohort of ETH students/employees.

The current COVID-19 pandemic has caused delays in initial or follow-up encounters between surgical patients and physicians. While this delay allows for resource allocation to those most severely affected by the pandemic, surgeons are faced with potential important delays in diagnosis and the expanding backlog of elective cases and initial evaluations. This project will assess surgeon and patient telemedicine perspectives. Pre-pandemic views on telemedicine among a cohort of surgeons will be obtained and compared to views at 3 months from the peak of the pandemic. Patients will be surveyed following telemedicine appointments with an anonymous questionnaire to learn about patient receptiveness to telemedicine. Barriers to implementation will be addressed throughout the duration of the study.
