Filter by:Vaccine hesitancy also concerns healthcare workers (HCWs). However, HCWs are at the frontline of the COVID-19 pandemic and identified as a priority target group for COVID-19 vaccines. Thus, the identification of interventions likely to improve COVID-19 vaccine attitudes and intentions among HCWs is of interests to increase the vaccine coverage among HCWs. The study hypothesis is that the use of the same chatbot as the one tested in the general population in France could also improve the COVID-19 vaccine intentions and perceptions in HCWs.
The pathophysiological processes involved in COVID-19 pneumonia are not fully understood. Specific alterations of the airways, lung parenchyma and pulmonary vascular tree could explain a severe ventilation/perfusion heterogeneity resulting in severe hypoxemia during the active phase of the disease. Additional skeletal muscle impairment related to systemic inflammation may also explain persisting symptoms in the follow-up phase. The first aim of the present project is to explore these different processes by evaluating the impact of the COVID-19 pneumonia on exercise capacity, pulmonary function and perfusion by a physiological and radiologic study. An ambulatory pulmonary rehabilitation will also be studied to assess its impact on the physiological parameter mentioned and the health-related quality of life questionnaire as a potential long-term treatment. The investigators propose a single center randomized controlled study at the University Hospitals of Geneva. 60 adult patients having suffered a hypoxemic COVID-19 pneumonia with persistent symptoms at 3-months after hospital discharge will be included. A functional and physiological study will be performed, including a six-minute walk test, pulmonary function testing, diffusing capacity for carbon monoxide, maximal inspiratory pressure and sniff nasal inspiratory pressure. Those with at least one abnormal value will be invited to fill the Saint Georges Respiratory Questionnaire, the Short Form 36 and the Hospital Anxiety and Depression Scale and will undergo a chest dual energy computed tomography (DECT), a cardiopulmonary exercise testing with non-invasive cardiac output and stroke volume evaluation and an evaluation of the pulmonary shunt by hyperoxia (100% oxygen breathing) at rest and during light effort. Then patients will be randomized on a 1:1 basis for pulmonary rehabilitation program or usual care. All work-up except DECT will be repeated at 6 and 12 months after hospital discharge. The investigators hypothesize that our study will allow a better understanding of pathophysiological mechanisms involved in COVID-19. This will potentially determine therapeutic target for patients with persisting symptoms and functional decay after COVID-19. The investigators also expect to see an improvement of exercise capacity and physiological parameters in the pulmonary rehabilitation group, as compared to the control group, suggesting pulmonary rehabilitation as a possible long-term treatment of this condition.
Immune aging or immunosenescence is characterized by a loss of T cell clonal diversity and a contraction of naïve T cells with proliferative capacity associated with the functional impairment of many others immune cells as well as a chronic low degree of inflammation. A restrictive T cell repertoire is likely more prone to antigen-mediated exhaustion observed during chronic viral infections. Notably, lymphopenia is the most consistent laboratory abnormality in COVID-19 infected patients and both lung-resident and circulating T cells potently up-regulate markers of T cell exhaustion. It is not clear today if the association of COVID-19 disease severity with age is mainly related with the immunosenescence of infected patients. Interestingly, T cell exhaustion and premature immunosenescence have also been observed in chronic inflammatory diseases such as rheumatoid arthritis (RA). To better understand the immunological mechanisms involved in SARS-Cov-2 pathophysiology, the investigators propose to compare the immunosenescence patterns observed during RA, aging and SARS-Cov-2 infected patients in order to design improved therapeutic interventions.
The study is a Randomized, Open-Label, Multi-Centre, Phase 2a Study to Evaluate the Safety and Effect of STC3141 Continuous Infusion in Subjects with Severe Corona Virus Disease 2019（COVID-19）Pneumonia.
Aerosol Generating Medical Procedures (AGMP) are procedures that have the potential to create tiny particles suspended in the air. These particles can contain germs such as viruses. The current Coronavirus Disease 2019 (COVID-19) pandemic is caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Patients infected with SARS-CoV-2 experience unusually high rates of critical illness that needs advanced airway management and intensive care unit admission. Bag-valve-mask (BVM) ventilation, laryngeal mask airway insertion (LMA), and endotracheal Intubation (ETI) are common AGMP for critically ill COVID-19 patients, and may contribute to a high risk of infection amongst Health Care Workers (HCW). To lessen HCW risk during high-risk AGMPs, a device called an aerosol box has been developed to place over the head of the patient, shielding the provider's face from virus droplets suspended in the air. The purpose of this research study is to better understand how particles disperse during AGMPs. The project team hopes what is learned from the project can help inform infection control measures. This could help make changes to the clinical environment and make it safer for HCW's. The investigators intend to investigate how an aerosol box performs in reducing contamination of HCW's who perform critical airway interventions.
This trial is a randomized, double-blind, placebo-controlled, parallel-group, 2-arm, multicenter trial to evaluate the efficacy and safety of C21 versus placebo as add-on to standard of care (SoC) in adult subjects with COVID-19. The trial planned to enroll a total of maximum 300 randomized subjects, 150 per arm (oral C21 100 mg twice a day (BID) or placebo for 14 days) according to the 1:1 randomization.
Post-marketing study, Cohort study of COMIRNATY vaccines. To collect information on adverse events and COVID-19 observed after vaccination with COMIRNATY and to assess safety in patients with underlying disease considered to be at high risk of aggravation of COVID-19 who have received vaccination with this product under actual use conditions.
The main aim is to validate non-gated 5-min computed tomography myocardial relative enhancement (CT-MRE), which can be readily estimated via contrast-enhanced non-gated chest CT, as a tool for estimating myocardial extracellular volume (ECV) using cardiac magnetic resonance (CMR)-derived ECV as a reference standard in a consecutive series of patients scheduled for cardiac CT. A secondary explorative aim is to evaluate the presence and extent of possible myocardial alterations in those patients enrolled in the VALETUDO study who have been infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
This is a phase I study to evaluate the safety and efficacy of inhaled Ampion on patients with prolonged respiratory symptoms due to COVID-19 (Long COVID).
This study investigates whether or not the stretching and strengthening exercises are effective both at home and under supervision for people suffering from neck pain from using equipment for online courses due to quarantine during COVID-19.
