There are about 6193 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 Clinical Research Collaboration is to investigate the prognostic implications of pulmonary hemodynamics during exercise based on a large scale multi-centre approach by using retrospective and prospective analysis of hemodynamic data.
The suprascapular nerve innervates the musculi supra- and infraspinatus, which, as part of the rotator cuff, allow lifting and external rotation in the shoulder joint. Damage to this nerve can lead to pain and functional deficit. Causes of injury are compression by bony / ligamentous anomalies, fracture sequelae and traction damage. In the literature, a (often subclinical) traction damage is increasingly claimed by a muscle retraction after rupture of the supra- and / or infraspinatus tendon as a cause of pain and functional disturbances. The retraction of the ruptured tendon-muscular unit is said to lead to traction damage of the nerve, which can be demonstrated by pathological EMG derivations. By repositioning the tendon to its outbreak site, the nerve is occasionally overstretched, so that individual authors propagate a routine nerve decompression as prophylaxis. In individual cases, a previously pathologic EMG result could be improved after reconstitution of an rotator cuff rupture. However, prospective studies are not available. It is not known how often a nerve damage is present before a rotator cuff operation and it is not known how often the tendon repair leads to nerve damage or recovery of damage. It is not known whether the surgical nerve decompression is associated with reduced postoperative pain and what a profit or what risks bring about a routine decompression of the nerve to the patient. To answer this question, this prospective randomized study is to be carried out.
Comparison of two different pediatric emergency rulers for length-based body weight estimation in pediatric emergencies. Primary outcome is the time needed to identify four defined parameters from the pediatric emergency rulers during a low-fidelity pediatric emergency scenario (cardiac arrest). Secondary outcome is the correctness of the identified parameters and the percentage deviation from the correct value.
This trial will be designed as a multi-center randomized non-inferiority clinical trial to demonstrate safety and efficacy of the FEMTO LDV Z8 laser for cataract surgery in a Chinese population in China compared to the conventional technique.
The reason for this study is to see if the study drug called baricitinib works and is safe in children and teenage participants with atopic dermatitis.
This retrospective observational study analyses the surgical performance, clinical and radiologic outcome as well as the rate of infections with a main focus on revision surgeries after primary implantation of the Optimys short stem femoral prosthesis.
This study is to quantify changes in muscle activity and pelvic stability during prolonged walking in patients with symptomatic lumbar spinal stenosis (sLSS) and healthy control subjects and to determine their association with the severity of the stenosis and the crosssectional area and fatty atrophy of lumbo-pelvic-hip muscles.
A 5-year chart review study of patients with haemophilia A with inhibitors treated with rFVIIIFc (Elocta®) for immune tolerance induction.
Coronary artery disease and the benefit of bypasses: Despite considerable advances in medicine, cardiovascular diseases remain the number one cause of death globally, primarily consequence of myocardial infarction (MI). Coronary collaterals exert a protective effect by providing an alternative source of blood flow to a myocardial territory potentially affected by an acute coronary occlusion. Coronary collaterals represent pre-existing inter-arterial anastomoses and as such are the natural counter-part of surgically created bypasses. Sufficient coronary collaterals have been shown to confer a significant benefit in terms of overall mortality and cardiovascular events. In this regard, the concept of augmenting coronary collateral function as an alternative treatment strategy to alter the course of CAD, as well as to control symptoms, is attractive. Durable promotion of coronary collateral circulation: Before the advent of coronary artery bypass grafting, permanent augmentation of coronary collateral supply by a single structural modification has already been attempted. Bilateral ligation of the internal mammary arteries (IMA) was performed in CAD patients to alleviate angina pectoris and electrocardiographic (ECG) signs of ischemia. The prevalent in vivo function of natural internal mammary arteries (IMA)-to-coronary artery bypasses and their anti-ischemic effect has been recently demonstrated by the investigators' research group. Levels of collateral function and myocardial ischemia were determined in a prospective, open-label clinical trial of permanent IMA device occlusion. In this study, coronary collateral function, has been shown to be augmented in the presence vs the absence of distal permanent ipsilateral IMA occlusion. These findings have been corroborated by the observed reduction in ischemia in the intracoronary ECG. After this first step, the concept of permanent right IMA occlusion will be now investigated with a randomized, sham-controlled clinical trial.
