Filter by: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.
Phase I / II multicentre, randomized and controlled clinical trial to evaluate the efficacy of treatment with hyperimmune plasma obtained from convalescent antibodies of COVID-19 infection.
This study will describe and explore the recovery process of patients undergoing cardiac surgery during the covid-19 pandemic. This will include mortality, morbidity, health-related quality of life, event-specific distress and depression.
The trial will be done to determine the impact of a barrier enclosure, COVID (coronavirus disease -19) barrier box on endotracheal intubation attempts, and duration. This study will be a prospective, open-label, randomized controlled trial. A total of 100 patients scheduled for elective surgery will be randomly assigned in two groups (intervention group and control group). Participating attending anesthesiologists will intubate the intervention group patients with COVID barrier box and the control group patients without the box. The anesthesiologists and the intervention group patients will be surveyed about their perception after the surgery. The result of this study will help in decision making about using COVID barrier box to minimize the viral transmission from patients to healthcare workers during the pandemic.
In this study we propose to treat 560 patients with ramipril or placebo for 14 days. After an initial evaluation for COVID-19 status, medical history, and symptom assessment, patients will receive either 2.5 mg/day of ramipril or placebo. Patients' symptoms and study endpoints will be monitored at regular intervals. After 14 days, patients will undergo a laboratory assessment and an end-of-treatment follow-up visit at day 28. The primary endpoints of successful therapy will be improved survival, reductions in ICU admissions, and/or reductions in use of mechanical ventilator support.
Investigators use clinical data from a large sample of COVID-19 disease patients to screen out biomarkers associated with disease severity. Then, a novel nomogram model will be established to predict covid-19 disease severity, which could provide important assistance and supplement for clinical work. In the case of extremely shortage of front-line medical resources, patients with potential severe diseases will be timely treated with the help of the novel nomogram model.
The prone position during mechanical ventilation in patients with Acute Respiratory Distress Syndrome (ARDS) is able to improve oxygenation and thus reduce mortality. The objective of the study is to evaluate the ability of the prone position to increase the oxygenation of the patient with SARS-cov-2 pneumonia.
Describe the main clinical features impacting the food intake, and therefore the nutritional status of a population infected by a coronavirus.
Several treatments have been used in during the Covid-19 pandemic of 2020. Using patients' registries from several hospitals in Paris, the investigators retrospectively analyzed associations between specific treatments, including but not limited to vaccines targeted against SARS-CoV-2, hydroxychloroquine, azithromycin, remdesivir, baricitinib, tocilizumab, sarilumab, lopinavir/ritonavir and oseltamivir; and clinical outcomes including, death and mechanical ventilation.
The aim of this study is to investigate the efficacy of pulmonary rehabilitation(PR) applied in the isolation processes of post-acute patients with mild and moderate symptoms who had positive COVID-19 test on dyspnea,muscle pain,chest expansion,lower limb muscle strength and dynamic balance,fatigue,anxiety and depression.
