The aim of this study is to evaluate the impact of endometriosis on folliculogenesis and oocyte quality. To do so, a metabolomic approach will be conducted in order to analyze the follicular fluid. This evaluation will be completed by a transcriptomic analysis from the cumulus cells of the oocyte. The normal and pathological oocyte cohort after controlled ovarian stimulation will be also characterized by identifying the oocyte leading to live birth.

This study is to establish a noninvasive diagnostic platform based on hemodynamic information for the assessment of liver fibrosis, liver cirrhosis and portal hypertension.

To develop a patient-reported questionnaire to investigate the impact of PAH (pulmonary arterial hypertension) on patients' daily lives in terms of bothersomeness and disability.

Patients with chronic obstructive pulmonary disease (COPD) are 2-3 times more likely to occur together with chronic gastrointestinal tract (GIT) diseases, such as inflammatory bowel disease (IBD) or irritable bowel syndrome (IBS). Similarly, despite many patients have no history of acute or chronic respiratory disease, up to 50% of IBD patients and 33% of IBS patients have pulmonary involvement, such as inflammation or impaired lung function. Increasing evidence indicated chronic gut and lung disease share key conceptual features with the disorder and dysregulation of the microbial ecosystem. However, the underlying mechanisms are not well understood. Our study is aimed to elucidate the intimate relationship between the gastrointestinal tract and respiratory tract, and uncover the mechanisms by which the gut microbiota affects the immune responses in the lungs, and vice versa.

FEVRIER study is an observatory of hospitalizations in cardiology units in sub-Saharan Africa.

To investigate the relationship between initial ClearSight™ derived hemodynamic parameters and outcomes (death, ongoing organ dysfunction or delayed ICU admission) in patients with acute infection and possible sepsis, with a focus on venous blood lactate (< 2.0, 2.0-3.9, and ≥ 4.0 mmol/dL) and hemodynamic subgroups, using ED patients presenting with minor infections or asthma/COPD exacerbations as controls (henceforth referred to as Sepsis Mimic Group).

The aim of this observational study is to examine supplementation (e.g. caffeine or creatin) use in both male and female professional tennis players.

The purpose of this study is to pilot data for a systematic molecular characterization of pathophysiologic perturbations incurred by snake envenomation and compare this to other inflammatory physiologic states such as trauma and sepsis. This sub-study will analyze samples of participants enrolled under the parent study "Surgical Critical Care Initiative Tissue and Data Acquisition Protocol".

assess diagnostic performance of 3-Tesla DW-MRI in detecting and staging bladder cancer and potential role of the ADC value as a biomarker reflecting histological grade and stage.

Cardiovascular disease remains the leading cause of morbidity and mortality worldwide. Coronary computed tomography angiography (CCTA) and, if indicated, invasively measured fractional flow reserve (FFR) is currently used for ruling out significant coronary artery disease. FFRCT is a novel non-invasive technique in which FFR is derived from CT images, however this method is currently, just like CCTA, lacking specificity. Spectral Detector CT (SDCT) is a novel technique whereby a spectrum of monoenergetic images at different kiloelectron Volt (keV) values (40 to 200 keV) can be reconstructed. By using these monoenergetic images, a decrease in blooming and beam-hardening artifacts could be achieved. In addition, SDCT offers the opportunity to assess myocardial iodine distribution and quantification. When combining these factors, we hypothesize more accurate information will be available about the coronary anatomy, degree of stenosis and FFRCT and thereby contribute to a more accurate way for the detection of hemodynamic significant stenosis. Therefore, the aim of this study is to assess the accuracy of SDCT as a non-invasive way for the detection of hemodynamically significant coronary artery stenosis. Objective: The overall objective of this project is to assess the accuracy of SDCT for the detection of flow limiting stenosis in the coronary arteries using invasive FFR as the standard of reference. Whereby different sub-aims (e.g. improvement of FFRCT) are made to answer the overall objective. The secondary objective is to determine the decrease of calcium blooming of calcifications and beam-hardening artifacts and the improvement of myocardial blood volume quantification on SDCT in comparison with conventional CT.
