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.
Our overall hypothesis is that a sudden ambulatory load reduction (caused by corrective osteotomy) leads to changes in cartilage biology that delay or reverse osteoarthritic processes determining the clinical outcome and representing an in vivo model for assessing cartilage mechanosensitivity.
The study aims to determine the effect size of magnesium and bicarbonate supplementation as a basis for future randomized controlled trials aiming at the T50-guided improvement of hard clinical endpoints in dialysis patients.
The primary objective of this study is to investigate the impact of continuous renal replacement therapy and intermittent renal replacement therapy on microbubble / cerebral microemboli generation in a cohort of critically ill patients with dialysis-dependent acute kidney injury.
Monosymptomatic nocturnal enuresis (MEN) is a common problem in children, affecting 7-10% of all 7 year olds. MEN is often leading to psychosocial problems because of its burden and stigmatism. The only available medical treatment option is the vasopressin analogum Desmopressin®. However, according to the literature, only one third of patients shows a good treatment response, defined as more than 90% of reduced bed wetting. Furthermore, treatment with Desmopressin® may lead to psychosocial problems, high costs and potentially dangerous side effects like water intoxication and hypertension. Copeptin, mirroring arginine vasopressin (AVP), has been shown to be significantly lower in patients with MEN compared to controls and lower in patients with severe bed wetting compared to patients with only slight bed wetting.
The study intends to investigate a novel compression system termed Socknleg composed of an understocking covering the foot with three added stockings extending from the ankle to the knee without covering the foot. The novel Socknleg system is compared to a standard class III compression stocking.
The purpose of this multi-center, non-interventional, prospective, post-market clinical study is to collect real world data on patient outcomes and evaluate the procedural success and performance of the Lifetech CeraFlex™ occluders for patients with secundum type Atrial Septum Defect (ASD), Patent Foramen Ovale (PFO) or Patent Ductus Arteriosus (PDA).
This study is designed to evaluate the potential effect of administration of tradipitant on CYP3A4 using midazolam pharmacokinetics as markers. The study will also further characterize the pharmacokinetics of tradipitant.
There is a high prevalence of vitamin D deficiency in Switzerland. In indoor-athletes as well as wheelchair users, vitamin D deficiency occurs even more often. It is well established that vitamin D deficiency has a negative effect on health. However, vitamin D supplementation in individuals with a vitamin D deficiency has a positive effect on muscle performance. In recently published studies with able-bodied subjects, it has been shown that a normal vitamin D level (>75nmol/L) can only be achieved with a high-dose supplementation of vitamin D. The aim of this study is to examine the effect of vitamin D supplementation on exercise performance in wheelchair athletes with vitamin D deficiency . All participants with a vitamin D deficiency are assigned to the intervention group and treated with 6000 IU of vitamin D3 daily over a period of 12 weeks. All participants who have a normal vitamin D level will receive placebo treatment (control group). The physical performance is measured three times at baseline, after six weeks and 12 weeks. The measurements include a Wingate and a dynamometer test.
The purpose of this prospective single center study is to investigate if a developed algorithm is more accurate than the Broselow Tape (BT). For this study 500 patients are required to collect anonymized data (length, weight, age, anaesthesia material used during anaesthesia) for achieving a power of 80% during statistical analysis. The main hypothesis ist that the algorithm has a better accuracy than the BT.
Skin prick tests (SPT) are commonly used in daily allergological practice to assess skin reactivity to allergens. Multiple factors can contribute to non-optimal results of conventional wheal and flare measurement (CWFM) of SPT such as inaccurate measurements, observer-dependency and absence of traceability. This study aims to evaluate the quantification of SPT by a novel High Speed Laser Doppler Imaging (HSL-DI) and to compare it with CWFM. First, SPT with birch and/or grass pollen extracts as well as positive and negative controls will be performed in 20 volunteers (11 atopics, 9 non-atopics) to establish the characteristics (cut-off, optimal reading time and allergen concentration) of HSL-DI analysis based on two parameters ("area" and "flow" measurement). In a second step, fifty patients will be tested with birch and grass pollen extracts at optimal allergen concentration and time window. Analysis of SPT by HSL-DI and CWFM will be compared.
