The investigators will evaluate the determinants of cerebral impairment in patients with non-ischemic heart failure compared to controls, and its relation to cognitive function. They hypothesize that patients with heart failure have impaired brain perfusion and hemodynamic factors are associated with cognitive dysfunction.

The purpose of this study is to determine whether whole-body MRI (WB-MRI) accuracy is superior to FDG-PET-CT considered as the gold-standard for the staging of distant lesions of rectal cancer.

Comparison of noninvasive glucose measurement performance versus standard invasive reference measurements.

An adnexal mass is the most common indication for gynaecological surgery . Pre operative characterization is crucial and a scoring system would be useful to standardize the imaging report and thus, improve patient management. Recently, our center developed the first MR scoring system named ADNEXMR SCORING system in a retrospective study which is accurate and reproducible (1). Our objectives are to perform an external prospective validation of this scoring system, to evaluate its potential impact on therapeutic strategy and to test its reproducibility. This is a prospective large multicenter study. All patients with a sonographically indeterminate adnexal mass referred for MR imaging will be consecutively included in each center. Then, patients will undergo a routine pelvic MR imaging. Prospectively, one senior and one junior radiologists independently analyze the different MR criteria to characterize adnexal masses. The MR report will be issued as standard and the patient will be managed accordingly. Then, the reader will classify the mass using ADNEXMR SCORING system. The classification will be compared to the reference standard as defined below. The reproducibility of the classification will be tested between the junior and the senior radiologist. After anonymisation, images will be analyzed by another senior radiologist of another center blinded from any clinical or ultrasonographical data and correlated with the reference standard. Reference standard: Reference standard will be surgical procedure with histology or standard clinical follow-up depending on most appropriate routine practice. Sample size: The sample size was computed to ensure a power of at least 90% (with a two-sided type I error rate of 5%) to conclude that SCORE 2 and 3 and SCORE 4 and 5 would have a different PPV. It would thus be necessary to have at least 569 patients classified as SCORE 2, 259 as SCORE 3, 52 as SCORE 4 and 51 as SCORE 5 (18). Given the prevalences, and assuming 6% of patients would be classified, as SCORE 1 and 10% would be lost to follow-up, 1340 patients will be included in this study to insure a probability of at least 95% to obtain the aforementioned number of patients in each score category. The inclusion period will last 18 months (extension for a period of 12 months) and monitoring will continue for 2 years. Thomassin Naggara I., et al.

The primary objective of the study is to validate an EEG base algorithm system to detect and monitor changes in cerebral electrophysiological parameters as compared to clinical evaluation in patients undergoing Carotid Endarterectomy. The secondary objectives is measure time from ICA clamping to algorithm asymmetry detection, time from clinical deterioration to algorithm asymmetry detection Thi study is a prospective, open label, single arm, self control, single center study. This study will be conducted in 50 subjects according to the inclusions/exclusions criteria.

The purpose of this study is to describe gastrointestinal (GI) motility in patients suffering from severe Ulcerative Colitis (UC) and to compare these results with similar results obtained in remission. The study is done with the use of Motilis 3D-Transit system which consists of a small electronic capsule ingested and detected by a receiver carried by the patient. Position and orientation of the capsule are interpreted by dedicated computer software and transit times, progression velocity and contraction frequencies can be revealed. The study is mainly descriptive and is designed to test and evaluate the usefulness of the Motilis 3D Transit system in UC patients and to tell investigators more about GI motility during and after severe inflammation. Motilis 3D-Transit system gives investigators a unique chance to study the gastrointestinal canal as a whole during and after severe illness. The investigators expect to include 20 patients suffering from severe UC admitted to Hospital with the purpose of getting medical treatment. The investigators do not expect any drop out, but in case of drop out a new patient will be included.

Pregnancies of patients with Diabetes are associated with increase adverse pregnancy outcome . The risk for vascular complications including: Intra uterine growth restriction (20%), hypertension (31%), preeclampsia (15%), eclampsia and placental abruption are significantly greater than those in background populations. The risk of developing vascular complications in diabetes pregnancies although is correlated with the severity and length of the disease is not fully understood. Enhanced oxidation has been suggested to be the underlying abnormality responsible for some of the complications of diabetes. Haptoglobin (Hp) is an abundant plasma glycoprotein produced in the liver. The best understood function of Hp is to bind free hemoglobin (Hb) released from red blood cells. Extracorpuscular Hb is a potent Fenton reagent.capable of of inflicting oxidative tissue damage. Hp binds to Hb and serves to inhibit the oxidative potential of Hb by preventing the release of heme iron. The haptoglobin (Hp) gene at chromosomal locus 16q22 is polymorphic, with two common alleles denoted 1 and 2. the prevalence of Hp 1-1, Hp 1-2 and Hp 2-2 genotypes is approximately 16%, 48% and 36%, respectively. In the western world. A total of five independent longitudinal studies have demonstrated that DM individuals with Hp 2-2 genotype have a two to five-fold increased risk of CVD as compared to DM individuals without the Hp 2-2 genotype We sought to determine whether HP genotype plays important role in development of vascular complications in pregastational pregnancies. and whether Hp genotype 2-2 is a risk factor for developing gestational diabetes (GDM)

This will be a retrospective study. Details on all women who delivered in McGill University between 2001-2007 will be retrieved anonymously from the MOND database (McGill University Obstetrics and Neonatal database). Women will be divided to 2 groups according to their smoking status in pregnancy. Obstetric complications will be recorded in both groups.

Stroke is an important cause of perioperative morbidity and mortality, particularly in patients > 60 years. In cardiac, neurological and carotid surgery the incidence is known to be high (2.2-5.2%). However, little is known regarding perioperative stroke following other types of surgery including general, urological, orthopedic, thoracic and gynecological procedures. We therefore propose to undertake a multicenter, observational cohort study, to determine the current incidence of, the risk factors for, and outcome associated with perioperative stroke in patients undergoing non-cardiac and non-neurological surgery.

Myocardial infarction (MI) outcomes strictly depend on the time to reponed the infarct-related coronary artery. Networks have been activated in the last years in many countries to achieve fast track access of patients with ST-elevation MI to hospital with h24 primary PCI availability or directly to Cath Labs. From 2011 a regional STEMI network have been formally activated in Piedmont. The aim of our registry is to monitor the activity of the STEMI network in the large suburban area of Novara (population of about 800.000 subjects).
