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.
Multimodal training, including physical and cognitive activities, has been associated with a reduction in age-related physical and cognitive decline. Therefore, combining these activities into a home-based computerized training program may represent a powerful approach to foster independent life at home. The StayFitLonger study is a 6-month multi-site randomized controlled, double-blind trial, which tests the efficacy of a home-based computerized intervention that combines physical and cognitive exercises through virtual coaching to enhance motivation. In Switzerland, Canada and Belgium, a total of 128 older participants will be recruited and randomly assigned to one of two physical and cognitive home-based interventions for 6 months: StayFitLonger or active control training. The StayFitLonger intervention provides physical and cognitive training exercises, feedback and instructions through a virtual coach to optimize motivation. It also offers social and psycho-educational contents. Monthly supervision (home-visits and phone calls) will be provided during this 6-month intervention. Outcomes will be measured at baseline, and after 6 months of training. This study will demonstrate the feasibility, sustainability and efficacy of a home-based multi-domain intervention program allowing further development and possible commercialization of a scientifically validated training program to slow down cognitive and physical decline.
The primary objective of this study is to evaluate the effectiveness and safety of robotic-assisted endovascular embolization procedures compared to objective performance criteria for traditional, manual operation based on the scientific literature.
Cigarette smoking is the leading cause of preventable death in Switzerland and still more than a quarter of the Swiss population smokes cigarettes. Recently, electronic nicotine delivery systems (ENDS; also called vaporizer or electronic cigarette) have become popular with smokers who want to stop smoking or reduce their exposure to inhaled chemicals since ENDS use appears to be safer than tobacco smoking. Only two rigorous randomized controlled trials (RCTs) on the efficacy of ENDS to help smokers quit have been published so far. They have promising, yet inconclusive results, as the number of included participants were small. The safety and potential adverse effects of ENDS are also largely unknown. While the aerosol the users inhale appears safe in laboratory conditions, the difference in exposure to chemicals (such as reduction in exposure to volatile organic compounds) and effects of chemicals on the body (adverse events, improved health-related outcomes and measures of oxidative stress) between smokers who quit (with or without ENDS) and those who use ENDS for a long time have not yet been assessed in an RCT. This study will therefore test the efficacy of ENDS for cigarette smoking cessation, the safety of ENDS on adverse events and the effect of ENDS on health-related outcomes and exposure to inhaled chemicals. The primary hypothesis of this trial is that providing cigarette smokers willing to quit smoking tobacco cigarettes with ENDS leads to a higher rate of smokers who quit cigarette smoking than only smoking cessation counseling with nicotine replacement therapy (NRT), which represents nowadays the standard of care. For this trial, cigarette smokers motivated to quit smoking cigarettes will be included. Participants in the intervention group will receive an ENDS and nicotine-containing e-liquids, which they will be allowed to use ad libitum. Additionally, they will receive smoking cessation counseling. Participants in the control group will receive smoking cessation counseling only. Participants in both groups will be allowed to additionally use nicotine replacement therapy. All participants will be followed over a 24-month period. Smoking cessation counseling will be provided in person at the first clinical visit and then over the phone at the target quit date and again at week 1, 2, 4 and 8 after the target quit date. After 6,12 and 24 months, participants will be asked to come to a clinical visit.
To compare in diabetic patients eligible for percutaneous coronary intervention (PCI) with minimal exclusion criteria, the efficacy and safety of Abluminus DES+ sirolimus- eluting stents (SES) versus XIENCE Everolimus-Eluting Stents (EES). At least 40% of patients are expected to be affected by multivessel coronary artery disease and 30% with acute coronary syndrome
Accidental vaccine injection into adjunct shoulder structures can cause tissue damage, termed Shoulder injury related to vaccine administration (SIRVA). The immunopathological mechanisms and consequences of SIRVA are unknown. The study assesses the clinical and immunological consequences of an influenza vaccine if accidentally administered in periarticular space.
This study evaluates the effectiveness of an existing Specialised Paediatric Palliative Care programme and reports on its potential to improve patient-, family-, health professionals-, and healthcare-related outcomes. Data will be compared between an intervention and a comparison group.
Effects of a 6 months low-carb dietary intervention on glycemic control, body composition and gut-brain interaction in obese and lean patients with and without glucose intolerance or diabetes
The study's goal is to check and verify basic assumptions of a new selective mutism developmental model from Melfsen and Walitza through standardized and routinely used patient questionnaires. The primary emphasis is the question of a connection between selective mutism and high sensitivity, dissociation, emotional regulation, family structure, social anxiety and self-esteem.
The CoLiPri study is a cluster randomized controlled trial funded by the Swiss National Science Foundation to evaluate the clinical and cost effectiveness as well as the implementation of a complex consultation-liaison intervention to help improve symptoms of anxiety and depression of screened patients in primary care. The intervention includes expert consultations, on demand referral for structured mental health diagnostics, psychoeducation and treatment planning, as well as brief psychotherapeutic interventions and triage.
High field MR-technologies are expected to boost metabolic spectroscopic imaging (MRSI), but also CEST-MRI. This is due to the fact that increased SNR is available which can be used to increase the spatial resolution of all sequences, or reduction of measurement times. Recent findings has shown that MRSI can be used to evaluate the isocitrate dehydrogenase (IDH) status of gliomas, a brain tumor type which is most often diagnosed in humans. Patients with IDH-mutated gliomas have a much longer survival time that IDH-wildtype. In IDH-mutated gliomas the substance 2-hydroxy-glutarate (2HG) is found, whereas in IDH-wildtype gliomas it is not. The underlying trial aims to measure 2HG directly with different MRSI sequences at 3 Tesla (3T) and 7 Tesla (7T) magnetic field strength. Apart from MRSI-techniques for IDH-typing it has been shown that CEST-imaging can also be performed to determine the IDH-status of gliomas. A total of 75 patients and 50 healthy controls will be examined in this study to evaluate the most accurate method for pre-operative IDH-status determination.
