NCT ID: NCT03994029 Recruiting - Obesity, Childhood Clinical Trials

Effect of Polyphenol Supplementation on Hepatic Steatosis and Vascular Compliance

Start date: July 4, 2021
Phase: N/A
Study type: Interventional

The main objective is to study the effect of polyphenol supplementation on hepatic steatosis as measured by hepatic ultrasound, hepatic magnetic resonance imaging and on intima-media thickness and vascular elastography in obese adolescents known for hepatic steatosis as diagnosed by liver biopsy

NCT ID: NCT03097679 Active, not recruiting - Stent Restenosis Clinical Trials

Self-expanding Nitinol Stents of High vs. Low Chronic Outward Force in De-novo Femoropopliteal Occlusive Arterial Lesions

BIOFLEX-COF
Start date: October 1, 2015
Phase: N/A
Study type: Interventional

The objective of the BIOFLEX-COF trial is to investigate differences in formation of intimal hyperplasia at one and two years after implantation of nitinol-stents with high vs. low COF in de-novo femoropopliteal occlusive lesions in patients with symptomatic peripheral arterial disease. The BIOFLEX-COF trial is a prospective, randomized controlled trial. 80 subjects will be enrolled and randomly assigned to either a high COF group (LifeStent Vascular Stent) or low COF group (Pulsar).

NCT ID: NCT00379366 Terminated - Thrombosis Clinical Trials

External Ionizing Radiation to Prevent Restenosis on Haemodialysis Vascular Access

RASTA
Start date: December 2006
Phase: Phase 2/Phase 3
Study type: Interventional

Although ionizing radiations have been proposed for the prevention of intimal hyperplasia in coronary and peripheral arteries, information is lacking on how irradiation may prevent neointimal smooth-muscle cell proliferation and restenosis on prosthetic haemodialysis vascular access. We will assess the preventive effect of one dose of radiations (14 Gy) administered transcutaneously one day after dilatation of stenosis on prosthetic haemodialysis vascular access in a randomized controlled trial with a standardized clinical and ultrasonographic one-year follow-up.
