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.
Evaluation of the safety and performance of the Navitor TAVI System in a Global Study
Commercially pure (CP) titanium is the gold standard to produce dental implants because it has a huge volume of scientific publications over a period of more than 50 years, it is cheap and simple to produce (i.e., making dental implants economically "affordable") and comes in numerous specitic designs of screws tor various indications. That is why more than 95% of the implant market 5 dominated by titanlum. However, there is an innovation trend to manufacture implants from more inert and biocompatible materials. Ceramic implants represent a valuable alternative for expanding the patient base of clinicians, especially in cases with challenging aesthetic demand. Furthermore, there has been a significant increase in the number of patients requesting metal-free dentistry or bio-holistic implant treatments. In the past, ceramics were often branded as "inferior" quality due to its reputation as being brittle but the growing volume of scientific publications specifically an zirconia are demonstrating that lt is comparable in fracture-strength with titanium implants. There is a clear market niche for zirconia implants, especially in cases of: - Aesthetic reconstructions in the anterior region, especially in patients with a thin gingival biotype - Gingival recessions where a white colored implant is a great advantage - For patients with a titanium intolerance/sensitivity - For patients who prefer a bio-holistic/metal-free dental approach. Today, clinicians are asking tor long-term clinical results of zirconia as a dental implant material. Therefore, Z-Systems AG is conducting this zirconia dental implant registry. A registry design was chosen because it will capture long-term benefits/risks from clinical routine without patient selection.
The aim of this study is to evaluate the difference between the use of paper- versus application-based (smartphone application) exercises in the rehabilitation of intra-articular fractures of the distal radius at the Cantonal Hospital of Fribourg, Switzerland. The operation itself will proceed as usual. However, the rehabilitation will be aided by exercises based either on a paper support or on a digital application (smartphone application), in addition to follow-up by a hand therapist. The aim is to determine which support provides the best improvement in wrist mobility and function, and to speed up the return to work.
The aim of this randomised controlled trial is to compare the effects of an antenatal education class including a breathing and relaxation technique on self-efficacy compared to a standard antenatal education class without a focus on breathing and relaxation techniques.
The main study objective is to evaluate the long-term outcome in a prospective follow-up visit of patients who underwent hardware removal after surgical stabilization of rib fractures (SSRF) after a blunt chest trauma .
The purpose of this study is to evaluate the efficacy, safety, and tolerability of BMS-986278 in participants with Idiopathic Pulmonary Fibrosis.
The investigators aim to study the effect of SOT in participants with pulmonary vascular diseases (PVD) defined as pulmonary arterial hypertension or chronic thromboembolic pulmonary hypertension (PH) who permanently live >2500m on 6-minute walk distance (6MWD) assessed at 2840m.
The present study aims to assess the safety and feasibility of repeated transcranial alternating current stimulation (tACS) by the Miamind Neurostimulator in a cohort of healthy participants. Based on the findings of this investigation, subsequent clinical trials assessing the efficiency of tACS by the Miamind Neurostimulator for treatment of Alzheimer's Disease will be conducted.
The purpose of the study is to assess the usability of the PNA and satisfaction with the treatment within the framework of usual care remote nutritional counselling for GLP-1-supported weight management and collect pilot data on its potential to support weight loss.
The investigators propose a behavioral experiment with SEEG recording and stimulation, to both confirm the role of a brain region known as the anterior insula in identifying surprise, and disambiguate between competing principles behind adaptation: optimizing and satisficing. Optimizers continue to learn and adapt if performance can be improved, while satisficers are satisfied with a good enough performance and will cease adapting once that is reached. To study surprise signals in the anterior insula, a brain structure where these signals have been very prominent, the investigators will employ an experiment with subjects who are under SEEG (stereoelectroencephalogram) recording, that is, recording from electrodes which have been surgically implanted in the brain. These recordings will be done as patients perform a task where they try to anticipate the movements of a target on a line in two different learning environments (conditions). The experimenters will then determine whether these signals reflect surprise relative to past engagement with the environment, or surprise that reveals that the agent no longer feels in control because uncertainty is not in line with the reference model. If evidence is consistent with the former, adaptation reflects traditional reinforcement and aims at optimizing behavior. If evidence instead is consistent with the latter, behavior is guided by a prior model (a reference model) and behavior is satisficing. An fMRI study by d'Acremont and Bossaerts provides initial evidence that activation in the anterior insula supports the satisficing hypothesis, however it lacks the temporal granularity to completely rule out optimizing. In the current project, the investigators propose to use the higher time resolution of SEEG recordings to confirm these findings and reject the optimizing hypothesis. Additionally, stimulations of the anterior insula during a subset of trials will be used to determine whether insular activation following surprise signals and preceding changes in behavior (learning) is merely correlational or in fact causal. Stimulation will allow us to determine to what extent the subjects' sense of control and subsequent behavior can be influenced in accordance with surprise-based modeling of behavior. The cohort for this study will be patients with drug-resistant, focal epilepsy and who are hospitalized at the Hôpitaux Universitaires de Genève (HUG) for pre-surgical evaluation of their epilepsy using SEEG. The protocol will run in parallel with the patients' clinical procedures.
