This study aims to understand the onset an functional consequences of left ventricular interstitial fibrosis in patients with chronic kidney disease (stage 2 to 5), as well as assess whether transplantation results in a regression of cardiac fibrosis.Thus all patients will undergo: 1) a cardiac magnetic resonance imaging (MRI) scan to assess cardiac function and measure left ventricular interstitial fibrosis; 2) a cardiopulmonary stress echocardiogram to understand the functional consequences of fibrosis and rule out any underlying ischaemic heart disease; 3) a 24 hour holter monitor and electrocardiogram (ECG) to assess whether these patients are at higher risk of arrhythmia.
Quantification of hepatic fibrosis by IVIM sequences in 1.5T MRI.
This multicenter RCT is designed to investigate if TIPS with covered stents improves transplant-free survival for cirrhotic patients with early stage of refractory ascites compared to LVP+albumin during 1 year follow-up period.
Introduction: Bronchiectasis is a chronic lung disease in which the underlying condition causes permanent damage to the conducting airways. Bronchiectasis is associated with considerable morbidity and poor quality of life. While cystic fibrosis (CF) is the most common cause of bronchiectasis in childhood, non-CF bronchiectasis is associated with a wide variety of disorders. CF bronchiectasis patients show reduced daily habitual physical activity and exercise capacity. Cardiopulmonary exercise test (CPET) is increasingly gaining importance in clinical medicine and considered the gold standard exercise test for assessing aerobic exercise capacity. The test objectively evaluates exercise physiological functions, may help assess morbidity and predict the outcome and mortality in different clinical circumstances and may serve as a basis for individualized exercise prescription within the limitation of the disease. Unlike CPET in CF, there is a paucity of data on exercise capacity using CPET in non- CF bronchiectasis patients, and on the implications of physical activity on non- CF bronchiectasis morbidity and mortality. Aim: To evaluate and compare exercise capacity in CF and non-CF bronchiectasis patients. Methods: This will be a cross-sectional retrospective/prospective study population. The retrospective study will include data analysis of patients that preformed CPET as part of their clinical evaluation. In the prospective study, patients that are scheduled to perform CPET as part of their clinical evaluation will sign (or legal guardian) informed consent prior to participation. Patients will be recruited from the exercise clinic at the Pediatric Pulmonary Institute at the Rappaport Children's Hospital. Inclusion criteria: 1. Children and adults (age >7 years, height >125cm), with CF and non CF bronchiectasis. 2. Completed a maximal CPET test according to accepted criteria; (maximal VO2 > 80% predicted, maximal heart rate > 80% predicted, acceptable RER (RER > 1.0 in children (under 18 years), RER > 1.05 for adults) or reaching a VO2 plateau..3. Evidence of bronchiectasis in computed tomography (CT). Exclusions criteria: preforming submaximal CPET, lack of data from the exercise test, exacerbation of patient's condition within three days before the exercise evaluation, relevant related chronic diseases that affecting test results.
Study Design and Methodology - Study Population:Compensated Cirrhosis - Study Design: An Ambi Prospective Cohort study - Study Period: 2 Years - Sample size: Retrospective- All patients from Jan 2010 to Mar 2017 Prospective- Assuming the incidence of clinical decompensation is 5%/year.With alpha of 5%, power 80% we need to enroll 138 cases. Further assuming 20% drop out 166 cases will be enrolled. - Intervention: This is an observational study. No intervention will be given. Monitoring and assessment: All the routine investigation and clinical information will be collected at 6, 12,18 and 24 months.
Tobacco and alcohol are the two major risk factors for upper respiratory tract cancer (VADS).
Inflammatory aortitis probably represents a heterogeneous group, and the clinical experience accumulated over the last ten years, shared by the experts of the subject, is that the initial clinical, biological or radiological characteristics should make it possible to differentiate them and dismember the Nosological field. This will be an essential first step before studying prognosis, risk factors, and therapeutic options. The search for diagnostic criteria on a large series, similar to the study of classification of vascularites of the ACR in 1990, should make it possible to homogenize the diagnoses for the different teams working on the subject, and to begin work Collaborations, which alone can improve patient care in the future.
Cirrhosis is characterized by loss of muscle as well as fat mass, which increases morbidity and mortality before, during, and after liver transplantation. A common mechanism for the reduced muscle and fat mass in cirrhosis is an increased expression of the TGF (transforming growth factor)beta superfamily member, myostatin, in the muscle and adipose tissue. The present study will examine the expression of myostatin, its receptor and intracellular signaling pathways in the skeletal muscle and mesenteric adipose tissue in cirrhotic patients undergoing liver transplantation as compared to healthy controls undergoing planned abdominal surgery. 16 cirrhotic patients will be identified from the transplant list, and 16 healthy controls from outpatient surgery lists. Nutritional assessment will be performed, including anthropometry (triceps skinfold thickness, mid arm circumference), dual energy x-ray absorptiometry (DEXA), and bioelectrical impedance analysis (BIA). Rectus abdominis muscle tissue and omental fat tissue will be harvested in the operating room, and the expression of signaling proteins involved in skeletal muscle protein synthesis will be quantified. The investigator will also quantify the expression of genes involved in lipolysis and lipid synthesis. The investigator anticipates that the expression of myostatin will be higher in the skeletal muscle and adipose tissue of cirrhotics as compared to controls. There will be a reduction in the expression of the signaling proteins that regulate skeletal muscle protein synthesis, as well as the expression of genes regulating lipogenesis. The increased expression of myostatin will also correlate with reduced anthropometric and DEXA measurements of lean body mass and fat mass.
The investigators hypothesised that novel MRI metrics derived from myocardium post-gadolinium T1 mapping analysis will improve the current knowledge about the role interstitial fibrosis and cardiomyocyte hypertrophy in the development of left ventricular (LV) remodelling and clinical Heart Failure (HF). The investigators believe that these recently described variables will be associated with prognostically important indices in HF development.
