All clinical trials

The purpose of this investigation is to evaluate how early biomarkers of infection and inflammation perform in identifying patients at risk for poor outcome in sepsis and septic shock.

In this prospective observational cohort study the potential clinical consequences of antibiotic use in early life and perturbations in the gastrointestinal microbiota composition due to that antibiotic use are studied. It is hypothesized that altered microbiota may be an important underlying mechanism for impediments in the developing immune system. Differentiation will be made between a group of neonates who received antibiotics in the first week of life, and control infants who were not exposed to antibiotics in the neonatal period.

Systemic sclerosis is a rare disease. The early cardiac disease affects 10% of patients sclérodemiques. Heart transplantation in the early cardiac involvement in systemic sclerosis is exceptional. we see patient data analysis with systemic sclerosis who used cardiac transplantation to understand the primitive cardiac damage associated with systemic sclerosis

Observational, retrospective and perspective study with acute and chronic endpoints

Retrospective analysis of all patients receiving TAVI in the United Kingdom (UK). Stroke rates following TAVI are roughly 3%. There are several device and procedure related characteristics which may increase the risk of stroke. We will examine if there is a signal in the UK registry. This will be important is TAVI is to be extended down to lower risk patient cohorts.

The main objective is to identify obstacles and elements facilitating the implementation of a tracking device Broncho Pulmonary Cancer during the course of care. The secondary objective is to assess patient knowledge and information received on their previous occupational exposure during their professional activity. This is a prospective multicenter study of qualitative methodology through in-depth interviews conducted with patients treated at ICLN and CHU Saint-Etienne

Hip Muscle Strength in femoro-acetabular impingement participants versus normal controls. To investigate the hip muscle strength in a normal control group and compare this to patients who have a diagnosis of femoro-acetabular impingement (diagnosed clinically and with confirmed radiological features).

Portal hypertension (PH) results from the increase of portal flow resistance in fibrotic tissue of the liver in patients with chronic liver diseases, leading to complications such as varices formation and variceal bleeding, ascites formation, spleenomegaly and hypersplenismus, systemic haemodynamic disorders and porto-systemic shunts formation. Early detection of PH in patients with chronic liver diseases is clinically important as it should change patient management in order to prevent the formation/onset or recurrence of PH complications. Hepatic venous pressure gradient (HVPG) measurement is the gold standard for the assessment of the severity of PH. However, it is an invasive method with its risks, and relatively costly. On the other hand transient elastography (TE) emerged as a non-invasive, easy, safe and low cost method with the potential to assess the severity of PH, as liver stiffness (LS) and spleen stiffens (SS) measured by TE showed very good correlation with HVPG. Real-time 2D shear wave elastography (RT-2D-SWE) is an ultrasound elastography method reliable for non-invasive assessment of fibrosis stage especially in chronic viral hepatitis, but only preliminary data exist on the correlation of RT-2D-SWE measured LS/SS with and HVPG. In this study we hypothesized that LS and SS measured by RT-2D-SWE correlate with HVPG enabling RT-2D-SWE to be used for the assessment of severity of PH. The primary aim of this study is to analyse correlation between LS and SS as assessed by RT-2D-SWE and TE with the grade of portal hypertension as assessed by HVPG. The secondary aims are: 1) to analyse clinical outcomes of these patients in order to determine if LS and/or SS as assessed by RT-2D-SWE might predict adverse outcomes (liver decompensation, death or HCC development), and 2) to compare clinical performance (AUC) of RT-2D-SWE and TE for the assessment of the PH severity as well as for predicting clinical outcomes. Patients with suspicion of having compensated advanced chronic liver disease (cACLD) as assesed by non-invasive methods (transabdominal ultrasound, laboratory findings, FIB-4 and APRI score, and LS measurements by TE), will be included. Since positive predictive value of non-invasive methods for cirrhosis is generally not very reliable, these patients will be offered transjugular liver biopsy and HVPG measurements as gold-standard methods to define the stage of liver disease and severity of PH. These patients will undergo LS and SS measurements by RT-2D-SWE on Aixplorer SuperSonic Imagine ultrasound system and HVPG measurements as well, with transjugular liver biopsy performed during the same session. After SWE™ and HVPG measurement, 5-year follow-up is planned, including standard surveillance: laboratory findings, transabdominal US every six months and upper-GI endoscopy according to relevant guidelines, as well as treatment according to relevant guidelines as indicated: beta blockers, endoscopic variceal ligation, etiologic treatment and dietary measures. Appropriate statistical analysis will be undertaken after the enrollment period, as well as after follow-up period.

The investigators believe that there is an association between H. pylori infection and nutritional status and between H. pylori infection and cognitive development. The current study will examine this association in Israeli children, aged 6-12 years.

TAVI induced LBBB is a complication that occurs between 7 and 65 % of the cases, numbers that differ considerably between devices. There is an increased risk of progression to total AV-block at follow-up, with the risk of brady-arrhythmic death. The aim of the study is to elucidate the anatomical location of the conduction pathology of a TAVI induced LBBB. This could impact valve design and placement and thereby reduce the number of new LBBB induced by TAVI in the future. Furthermore, finding predictors for progression to a high degree AV block in the follow-up (and thus an indication for permanent pacemaker) could improve management of post-operative conduction abnormalities and prevent the risk of brady-arrhythmic death.
