Prospective Cohort of Patients With Critical Limb Ischemia Undergoing Revascularization
Peripheral Arterial Occlusive Disease is associated with a high risk of cardiovascular events. The critical ischemia stage represents the most severe stage of Peripheral Arterial Occlusive Disease, associated with decubitus pain and / or foot ulceration. The severity of this arterial involvement involves functional prognosis of the lower limb with …
Natural History in Primary Mitochondrial Myopathies
This is a longitudinal study in a cohort of patients with a genetic diagnosis of Primary Mitochondrial Myopathy to describe the natural history of the disease and identify clinical, biochemical, molecular, and radiological variables that allow evaluation of the severity and progression of the disease and may be useful in …
Observational Study on Extreme Hypofractionation for Localized Prostate Cancer
Radiotherapy (RT) is an established treatment option for localized prostate cancer (PCa), with cure rates similar to those of radical prostatectomy. In the last decade, conventionally fractionated RT (1.8-2.0 Gy per fraction to 78-80 Gy) has been replaced by moderately hypofractionated RT (2.3-3.65 Gy per fraction to 56-70 Gy). The …
Brain PERfusion Evaluation by Contrast-Enhanced UltraSound
The objective of the study is to assess brain tissue perfusion by contrast-enhanced ultrasound perfusion imaging (PerCEUS) in acute brain injuries. More precisely, it aims : to evaluate the heterogeneity of brain perfusion and thus diagnose brain tissue hypoperfusion with contrast-enhanced ultrasound. to correlate contrast-enhanced ultrasound with perfusion measurements by …
Endometriosis, Food Consumption and Fertility
To investigate parameters related to fertility in women with endometriosis in relation to food items.
Neurophysiologic Biomarkers in Rett Syndrome
The goal of this observational study is to identify candidate biomarkers in individuals with Rett Syndrome (RTT). The main questions it aims to answer are: Do these biomarkers change during clinical changes in individuals with RTT? Are biomarkers stable over time in clinically stable individuals? Do these biomarkers correlate with …
Cognitive Decline and Underlying Mechanisms in Asymptomatic Intracranial Artery Stenosis Patients
The purpose of this study is to explore the mechanism of cognitive impairment in patients with asymptomatic intracranial atherosclerotic stenosis(ICAS),and to examine the natural history and the pathogenesis of asymptomatic ICAS.
Exosome Cargo From Preeclampsia Patients
Although extensively studied, the cause of preeclampsia remains uncertain other than it is thought that the placenta plays a critical role in the development of preeclampsia. Recent data revealed that exosomes released from the placenta could cause preeclampsia by transporting specific cargo responsible for the pathophysiological changes associated with the …
Imaging Techniques for Identifying Factors of Sudden Cardiac Death Risk
Sudden cardiac death is a tragic event that strikes all age groups and is unfortunately increasing in prevalence. Because it is difficult to predict those at highest risk, this study is designed to test the hypothesis that new imaging techniques (magnetic resonance imaging [MRI] and computed tomography [CT]) are useful …
Basal Plasma Lithium Levels and Suicidal Events
Suicidal behavior is a major public health issue and there are currently no specific treatments for it. However, lithium, the reference treatment for bipolar disorder, have been shown to be effective in preventing suicidal risk. Apart from drug treatments, lithium is present in our environment and its levels varies from …
