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.
Peripheral muscle weakness is a predominant problem in patients with COPD and treated using exercise training in pulmonary rehabilitation. Despite pulmonary rehabilitation being an effective intervention, muscle strength impairment is a persisting problem in COPD patients. Patients have problems to tolerate the high training loads, which are necessary to develop strength. Low-load blood flow restriction training (LL-BFRT) might therefore be an option to enhance muscular response of patients with COPD to strength training. Up to now, no studies investigating LL-BFRT in respiratory diseases are available. The primary outcome of this randomized pilot study is knee extensor muscle strength. Secondary, the study will evaluate if LL-BFRT is well tolerated and feasible in COPD patients attending outpatient pulmonary rehabilitation.
Congenital heart disease (CHD) is the most common congenital defect, affecting about 1% of newborns. Among adults surviving complex CHD, the cohort of survivors after the Fontan palliation for univentricular physiology is the most rapidly growing. Given their unique physiology without a pumping chamber supporting the pulmonary circulation, their exercise capacity as adults is often severely reduced. Therefore, patients with grown-up CHD typically need long-term expert medical care causing constantly increasing healthcare- related costs. Specific exercise regimes might offer a safe, efficacious and cost-effective alternative to pharmacologic interventions and surgery. The underlying mechanisms of impaired exercise capacity in Fontan patients are, however, not fully understood and consequently, training regimes specifically tackling the limiting factors cannot be developed. In patients with CHD, studies have suggested that exercise limitations are secondary to the cardiac defects, factors related to cardiac surgery, chronotropic incompetence and underlying lung disease. Similar to heart failure patients, exercise limitations could be traced back to insufficient respiratory and leg muscle functions and impaired cardiovascular regeneration processes possibly due to an altered stem cell number and function in the peripheral blood. The present study will investigate cardiac, respiratory and quadriceps muscle function at rest and during submaximal and maximal whole-body exercises. A special focus will be given on respiratory and quadriceps muscle strength, and proneness of these muscles to fatigue, which has not yet been objectively investigated. Moreover, different respiratory muscle training (RMT) protocols will be executed, to assess the safety of these interventions. Moreover, the current study will be the first to investigate the influence of exhaustive exercise protocols on the number and function of circulating stem and progenitor cells (CPCs) in Fontan patients. The number of these cell populations was shown to strongly correlate with long-term outcome and recovery in several diseases. This study aims to reveal whether Fontan patients show similarly alternated stem cell number and function in the peripheral blood, that likely result in impaired vascular regeneration processes and possibly also contribute to reduced exercise capacity.
The trial will test whether a standard music program that is an offset to the general program provides the same benefit as a music program that is individually customized for each test participant. The trial seeks to investigate the benefit received by musicians that regularly play an instrument and belong to an organized music group or orchestra instead of people that listen to music.
The Purpose of the study is to show that the performance of the new feedback cancellation system is better than the feedback system used in the currently marketed hearing aids. Speech understanding should not be negatively affected by the new system, ad there should be no consequential artifacts or unwanted noises caused by the new system.
This study will evaluate whether the degree of central sensitization as measured by the questionnaire "central sensitization inventory CSI" is related to the outcome of surgical endometriosis treatment
Effects of serotonin 2A/1A receptor stimulation by psilocybin on alcohol addicted patients: a randomized double-blind placebo-controlled study
This is a prospective, multicenter, open-label, single-arm registry. The primary objective of this registry is to confirm the results of the Supraflex Cruz stent in real life all-comer patients (800 patients as in the Supraflex arm of the TALENT trial) and demonstrate that the Supraflex Cruz stent is not inferior to the BioFreedom stent in High Bleeding Risk (HBR) patients (400 patients) with respect to device oriented composite endpoint (DOCE) at 12 months. All patients will be followed up to 12 months after the index procedure.
BIOFLOW-DAPT is a prospective, multi-center, international, two-arm randomized controlled clinical study. A total of 1'948 subjects will be randomized 1:1 to receive either Orsiro Mission or Resolute Onyx. After index procedure, all patients will receive DAPT (ASA + P2Y12 inhibitor) for 30 days, followed by monotherapy with either P2Y12 inhibitor or ASA only until the end of the study. Clinical follow-up visits will be scheduled at 1, 6 and 12 months post-procedure.
In this pilot study the feasibility of continous monitoring of health data with a small, on-skin wearable device (the Everion®, by Biovotion, Zurich) in pediatric patients under chemotherapy for cancer, is studied. Feasibility is assessed by the number of patients wearing the device on seven consecutive days for at least 18h/day, what will be measured by monitored heart rate. Study duration for each participant is 14 days.
MET-REPAIR CONVAL is an international cohort study to examine the ability of self-reported exercise capacity to predict perioperative cardiovascular events correcting for preoperative risk factors.
