HF vs NIV in Acute Cardiogenic Pulmonary Edema
Pulmonary Edema Cardiac CauseThe study's primary aim is to compare the effects of two different ventilation modalities, non-invasive positive-pressure ventilation (NPPV) and high-flow nasal cannulae (HFNC), in the acute cardiogenic pulmonary edema (ACPE) setting, in terms of echocardiographic parameters of RV systolic and RV strain. to determine the differences of the two interventions on other hemodynamic parameters echocardiographically assessed. to assess the differences between the two interventions on physiological parameters, i.e., mean arterial pressure (MAP), heart rate (HR), respiratory rate (RR), oxygen saturation (SpO2), and on arterial blood gases (ABG) analysis parameters (i.e. relief of dyspnea and respiratory distress, patient comfort). Enrolled patients will receive NPPV and HFNC oxygen therapy in a randomized, cross-over fashion, for 40 minutes each (time 0, T0 and time 1, T1), followed by clinical and echocardiographic evaluation
Microinvasive Pars Plana Vitrectomy Combined ILM Peeling Versus Anti-VEGF Intravitreal Injection...
Diabetic Macular EdemaPars Plana Vitrectomy1 moreDiabetic macular edema (DME) is the main cause of vision loss in patients with diabetes. At present, anti-vascular endothelial growth factor (VEGF) intravitreal injection is the first-line therapy for DME, nevertheless, some patients do not respond well to anti-VEGF agents and often require multiple injections, which increases the psychological and economic burden of patients. Microinvasive pars plana vitrectomy (PPV) has been proven to be safe and effective for refractory DME. However, there are few studies on treatment-naïve DME. The purpose of this study is to explore whether early PPV combined with internal limiting membrane (ILM) peeling can reduce the treatment burden of DME patients, prevent vision loss, and maintain long-term stabilization of diabetic retinopathy.

MRI Assessment of Pulmonary Edema in Acute Heart Failure
Acute Heart FailurePulmonary Edema With Heart FailureResearchers are testing a more accurate way to measure how much fluid is in the lungs (also called pulmonary edema, or "increased lung water") in people with Heart Failure (HF) using MRI (Magnetic Resonance Imaging). There is little known about the exact level of lung water in patients with AHF or how these levels change from the time of hospital admission to discharge. The purpose of this research study is to measure the lung water in patients hospitalized for HF, to determine the change in lung water over the course of hospitalization and treatment, and to find out if lung water levels can predict if patients are higher or lower risk for returning to the hospital or dying from heart failure.

The study is a scientific evaluation of the ESD compared with water displacement volumetry and tape measure.
Oedema Study : Chroedem
Lower Limb Chronic OedemaThe chroedem study is aiming to assess tissue and biomolecular components of chronic lower limb oedema (CO). The investigators working hypothesis is that according to the aetiology of CO, the proportion of oedema & composition of peri-oedema tissues (fat, muscle, fibrosis/inflammation) might differ and could at least in part explain differences in failure/success of compressive therapies from one patient to another. For that purpose, 24 patients with a post-thrombotic syndrome (PTS)-related oedema and 24 patients with a primary lymphedema will undergo a magnetic resonance imaging (MRI)) of the legs and biological (genetic) testing.
