Effect of Mechanical Power on Dead Space Assessed by Volumetric Capnography: Preliminary Studies and Pilot Testing in ARDS Patients
This study assesses changes in physiological variables, aiming to determine whether a reduction in the mechanical power delivered by artificial ventilation while maintaining constant peep levels generates a reduction in the Bohrs dead space in patients with moderate to severe acute respiratory distress syndrome (ARDS). Commonly used ventilatory strategies aimed …
Investigation of Antibody and Immune Responses to SARS-CoV-2 Proteins
SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), has negatively impacted global health and requires more research to develop better tests and to improve disease treatment. The purpose of this research is to aid in the testing effort by collecting samples from people who have been diagnosed with COVID-19 …

Among patients receiving long-term immunomodulatory drugs, especially in the context of auto-immune diseases, there may be legitimates interrogations about the appropriateness of continuing treatment, without modification, in the current context. Juvenile Idiopathic Arthritis is concerns by these fears …
Comparison of Dual Task Gait Characteristics in Individuals With Amputation and Healty Individuals
In amputee, dual task has been found to cause a decrease in walking speed. However, there is no study of how gait characteristics are affected when the speed does not change. The aim of this study is to compare the time-distance characteristics of walking with single task, cognitive dual task, …
Hemodynamic Changes Due to Prone Position
Perioperative prone position may be associated with hemodynamic instability. The causes of instability have not yet been precisely elucidated. The aim of this study is to demonstrate physiological changes during prone positioning in healthy volunteers .
Non Exudative AMD Imaged With SS-OCT- Extension
The investigators wish to better understand the role of the choriocapillaris (CC) in the formation and progression of non-exudative in age related macular degeneration (armd) by imaging the retinal pigment epithelium (rpe) and the choroidal microvasculature and by studying their inter-dependence to determine if the loss of the CC could …
Design and Implementation of the Pediatric Liver Transplantation Biobank
The purpose of the pediatric liver transplant biobank is to systematically collect clinical specimens from pediatric end-stage liver disease. It is expected to contribute to the research and development of paediatric end-stage liver disease in the future.
Cardiac Biomarkers in Preeclampsia: Prediction of Disease and the Risk of Future Cardiovascular Events in Survivors
SUMMARY Background: Improvements in the management and prevention of obstetric haemorrhage and sepsis, in addition to magnesium sulphate for preeclampsia have led to significant reduction in global maternal mortality rates; thus leaving increasing number of survivors of preeclampsia than previously. Preeclampsia is associated with inflammatory changes that alter vascular integrity …
