There are about 9403 clinical studies being (or have been) conducted in Switzerland. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The purpose of this study is to provide clinical data pertaining to the safety and performance of the Globe® Mapping and Ablation System for treating patients with atrial fibrillation.
This study aims at assessing the hypothesis that dietary protein content is a major factor regulating lean body mass gain and energy expenditure during overfeeding, and thus long term body weight gain To test this hypothesis, healthy normal weight male and female subjects will before and after a 7-day hypercaloric, high-sucrose diet (+40% excess energy as sucrose) and either a low (5% total energy) or a high (20% total energy) protein intake. Each subject will be studied with both low- and high protein diets according to a randomized, crossover study. On each occasion the following measurements will be done in basal conditions (after 2-day isoenergetic, controled diet) and at the end of the 7-day overfeeding: - whole-body protein turnover, oxidation and synthesis in fasting conditions and fed conditions (13C-labelled leucine) - intrahepatic and intramuscular fat concentration (1H-Magnetic Resonance Spectroscopy) - Energy metabolism in fasted and fed conditions (indirect calorimetry) - plasma concentration of glucose, non-esterified fatty acids, total triglyceride, very-low density lipoprotein (VLDL)-triglyceride, insulin, glucagon, growth hormone (GH), insulin-like growth factor 1 (IGF1), insulin-like growth factor binding protein (IGFBP) 1,2 and 3 in fasting and fed conditions The effects of high-protein and low-protein sucrose overfeeding on whole body protein synthesis will be compared using two-way ANOVA; relationships between changes in whole body protein synthesis on one hand, and intrahepatic/intramuscular fat concentrations, total energy expenditure, and plasma concentration of metabolic variables on the other hand, will be evaluated by linear regression analysis
This clinical investigation is a prospective, non-randomized, multi-center, pivotal trial.This trial is being performed in order to demonstrate the sensivity of the diagnostic feature "Physiological Diagnostic" (PhD).
The hypothesis of this trial are that: - avoiding axillary surgery does not worsen the outcome of patients with small breast cancer the absence of the pathological information on the risk of recurrence given by nodal status is not worsening outcome of these patients - pre-operative imaging of the axilla can identify patients with clinically relevant nodal burden. The aims of this prospective randomized study are: - to verify whether, in presence of a negative preoperative axillary assessment, SLN can be spared - to verify whether, in presence of a negative preoperative axillary assessment, the decision on adjuvant medical treatment can be taken according only to the biology of the tumour without the prognostic information achieved by SLNB on the nodal status - to verify whether, in presence of a negative preoperative axillary assessment, the patients' quality of life can be improved by a less invasive surgical procedure.
The objectives of this registry are to 1. Collect clinical data on Boston Scientific's ImageReady MR Conditional Pacing Systems involving the INGEVITY lead based on observations / events 2. Gather data on actual number of MRI scans performed in the patient cohort implanted with an ImageReady system including information about scanned body parts. 3. Collect physician feedback on lead handling with the INGEVITY lead in a real-life, market-released standard of care environment using devices on intended purpose and which are authorized to bear the CE (Communauté Européenne) marking / are approved for use in the applicable area of participating centers. No additional invasive or other burdensome examinations are to be carried out other than the ones conducted by the centers per their general standard of care.
In assisted reproductive technology (ART) semen needs to be processed. Commonly used methods rely on physical properties of the spermatozoa, such as the swim-up methods and density gradient centrifugation. It is now known that current processing of spermatozoa does not prevent the admixture of spermatozoa with damaged genetic material. The latter have a negative impact on the outcome of ART. The investigators developed a new method for the processing of spermatozoa with intact genetic material based on flow cytometry and sorting (FACS) and on staining using a deye, YoPro. The investigators aim at examining the effect of this novel method of sperm sorting on the outcome of ART.
In the cross-sectional component of this study, our overall objective is to gather a large pool of data from which we can generate gait "profiles". These profiles will consist of a constellation of gait (+/- electrophysiological) parameters associated with a particular neurological diagnosis or specific lesion(s) in neuroanatomical systems. Once developed, these profiles can be compared for differences and similarities; allowing insights into the specificity of the effect on gait of a given diagnosis or lesion in the case of the former and redundancy of neuroanatomical systems in that of the latter. A longitudinal component of the study will look at the evolution of gait parameters over time in a group of patients with spinal cord injury.
Prospective, randomized, placebo-controlled, double-blind multicenter trial including 4 tertiary sacral neuromodulation referral centers in Switzerland (Zürich, Bern, Nottwil, St.Gallen). Patients with refractory neurogenic LUTD are included and randomized after neuromodulator implantation into sacral neuromodulation ON or sacral neuromodulation OFF (n=30) for a 2 months double-blind phase. In addition to standard neuro-urological assessments, patients who agree will also undergo neurophysiological investigation of the lower urinary tract, i.e. recording of current perception thresholds, sensory evoked potentials, and electroencephalography after stimulation of the urethra and bladder.
Quality control and improvement project: Assessment and analysis of processes and outcome in trauma emergency room and major trauma patients at the Aarau trauma center (cantonal hospital) with regard to initial emergency management, hospital processes and short- and long-term (1-and 2-year) outcome of patients (subjective and objective). Comparison of processes and outcome pre- and post- project initiative. Benchmarking with the literature and by participation in the German and Swiss Trauma registry each.
Retinopathy of prematurity (ROP) is a neovascular retinal disorder of premature born children, characterized by the development of retinal neovascularisation, macular dragging and eventually retinal detachment. ROP is a leading cause for childhood blindness, especially in developing countries. Vascular endothelial growth factor (VEGF) plays an important role in the development of the disease. Recently, the BEAT ROP study tested the efficacy of intravitreal bevacizumab for stage 3 plus ROP in a prospective, controlled, randomized, stratified, multicenter trial. Authors found that bevacizumab showed a significant benefit for Zone I but not Zone II disease, with continuation of peripheral retinal vessel growths after treatment. The authors also concluded that safety could not be assessed due to the small sample size. Other authors raised concerns regarding the results of the BEAT ROP study and the safety of bevacizumab. The investigators suspected a better safety profile for ranibizumab to treat stage 3 plus ROP. Here we present the outcome of 6 eyes with ROP stage 3 plus treated with a single injection of ranibizumab.
