Filter by:The goal of this single-center prospective, randomized, open-label clinical trial is to compare the effectiveness of imaging-based DBS programming with threshold assessment-based DBS programming in patients with Parkinson's disease and motor response fluctuations. The main question the study aims to answer is: Is the improvement of motor symptoms in the OFF-drug phase following STN DBS for Parkinson's disease, using imaging-based DBS programming only, non-inferior to the improvement of motor symptoms following DBS programming with threshold assessment at six months follow-up? Participants will be randomized to imaging-based programming or to threshold assessment-based programming. The main clinical outcome is motor symptoms; secondary outcomes are level of physical disability and quality of life, among others.
Biomarkers and mechanisms in the progression of aortic valve stenosis are sometimes not sufficiently understood. The current project will take into account image morphological and immunological aspects that predict the development of hemodynamically relevant aortic valve stenosis in order to identify high-risk patients and to develop further therapeutic options.
The management of acute adhesive small bowel obstruction remains challenging for the digestive surgeon. The Bologna guidelines recommend that conservative management of aSBO. The literature reports that this form of management has a failure rate between 10 and 40%. A radiological score has been proposed and was associated with an increased risk of failure of conservative management. This tool is promising to select patients further requiring surgery but it has to be assessed in a multi centric prospective cohort.
To examine inter-subject variations of optimal late arterial phase contrast-enhancement defined as the greatest difference in contrast attenuation of hepatocellular carcinoma (HCC) compared to background liver parenchyma resp. pancreatic lesions compared to pancreatic parenchyma. To evaluate which time-points best depict an optimal late arterial phase.
Phase 1/2 study of ALM-488 to highlight nerves in patients undergoing head & neck surgery.
This study will use magnetic resonance imaging (MRI) and ultrasound images to study how muscles, tendons, and bones work together to cause motion. The procedure is one of several tools being developed to characterize normal and impaired musculoskeletal function, with the goal of developing improved methods of diagnosis and treatment of movement disorders. Healthy normal volunteers must be age 5 to unlimited, with or without joint impairment, may be eligible for this study. Volunteers with joint impairment may not have serious injury to the joint being studied, previous surgery on the joint being studied, or extreme pain at the joint being studied. MRI uses a strong magnet and radio waves to create images of the inside of the body. The subject lies on a long narrow couch inside a metal cylinder (the scanner) for up to 3 hours while the scanner gathers data. Earplugs are worn to muffle loud noises caused by electrical switching of radiofrequency circuits used in the scanning process. A special pad or tube may be placed over or around the region being scanned to improve the quality of the data. The subject will be asked to repeatedly move a specific joint, such as the knee, for brief periods, usually less than 5 minutes. The subject can communicate via intercom with the person performing the study at all times during the procedure, and may request to stop the study at any time.
