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.
This is a postmarketing study to assess the overall performance and survivorship of the SIGMA HP® PARTIAL KNEE SYSTEM.
This is a Natural History study to characterize key aspects of the clinical course of late onset Lysosomal Acid Lipase (LAL) Deficiency/ Cholesteryl Ester Storage Disease (CESD).
TOPDOCS is a prospective cohort study including COPD patients from currently six study centers in Switzerland. Patients with COPD GOLD stages I-IV will be enrolled and followed-up annually for at least 3 years. Yearly assessments will include a detailed patient history, quality of life and activity questionnaires, history of exacerbations, lung function, measurements of exercise capacity, measurements of vascular function, exhaled breath analysis and blood sampling. The overall objective of the project is to establish a meticulously characterized cohort of COPD patients living in Switzerland in order to allow high quality research on the pathogenesis, treatment and complications of COPD. The specific aim of the project is to determine clinically relevant COPD phenotypes and biological factors influencing vascular function in COPD patients.
The aim of this trial is to assess the effect of hydrolyzed egg orally administered on oral tolerance induction to egg in children allergic to egg as compared to a placebo.
Kidney stones are very common in industrialized countries and the lifetime risk is about 10 to 15% in this population. Kidney stones are composed of inorganic and organic components. Calcium containing stones are the most common stone type accounting for more than 80% of kidney stones. Many factors predispose or contribute to the development of kidney stones, including genetic variants or mutations, diet, environmental factors, and behavior. To date, little is known on fibroblast growth factor (FGF23) levels in patients with calcium nephrolithiasis. FGF23 is crucial for phosphate homeostasis including physiological and pathophysiological conditions such as X-linked hypophosphatemic rickets and it seems that FGF23 is probably the most important regulator of serum phosphate and calcitriol (1,25(OH)2D3) levels in addition to parathyroid hormone (PTH) produced by the parathyroid gland. Novel factors such as Klotho and Sclerostin, which are involved in the bone-kidney-parathyroid endocrine axis, have been identified recently. Klotho is a putative aging suppressor gene and its deficiency results in osteopenia, hyperphosphaturia, and calcification. Klotho is mainly expressed in the kidney but also in the parathyroid gland and acts as a FGF23 specific co-receptor mediating FGF23 participation in the bone-kidney-parathyroid endocrine axis as described above. Sclerostin is a protein secreted by osteocytes that inhibits bone formation by osteoblasts. However, the potential role of FGF23, Klotho, and Sclerostin in nephrolithiasis is still poorly under-stood or even unexplored. The aim of this study is to test if levels of FGF23, Klotho, and Sclerostin are differentially regulated in kidney stone formers.
Data on quality of clinical anesthesia are important for the improvement of both quality and patient safety in this field. Routine quality data are often collected by professionals busy with patient care. This study examines the reliability of routinely collected quality data by comparing the electronic anesthesia record with the respective reports on quality-indicating events, i.e. whether events during the anesthetic (e.g., drop of blood pressure, irregular heart rhythm, and others) were actually reported or not. Additionally, interviews with reporting staff (physicians and nurses) are performed to gain insight in possible obstacles to reporting during the working process.
The purpose of the Registry is to provide continuing evaluation and periodic reporting of safety and effectiveness of Medtronic market-released products. The Registry data is intended to benefit and support interests of patients, hospitals, clinicians, regulatory bodies, payers, and industry by streamlining the clinical surveillance process and facilitating leading edge performance assessment via the least burdensome approach.
Computed tomography (CT) scanning has become essential in the early diagnostic phase of trauma care because of its high diagnostic accuracy. The introduction of multi-slice CT scanners and infrastructural improvements made 'total body' CT scanning (TBCT) technically feasible and its usage is currently becoming common practice in several trauma centers. However, literature provides limited evidence whether immediate 'total body' CT scanning leads to better clinical outcome then conventional radiographic imaging supplemented with selective CT scanning in trauma patients. The aim of the REACT-2 trial is to determine the value of immediate TBCT scanning in trauma patients. The investigators hypothesize that immediate 'total body' CT scanning during the primary survey of severely injured trauma patients has positive effects on patient outcome compared with standard conventional ATLS based radiological imaging supplemented with selective CT scanning.
The primary objective of the drug-drug interaction study is to evaluate any drug interaction between the CYP2D6 substrate metoprolol and pyronaridine-artesunate in healthy volunteers. The primary objective of the pyronaridine-artesunate redosing study is to determine the safety of redosing a 3-day regimen of pyronaridine-artesunate following 60 or 90 days in healthy volunteers.
There is growing but limited information on the long term clinical status of aHUS patients who have previously received or are continuing to receive treatment with eculizumab. This study is designed to collect clinical data that will provide insight into the long-term outcomes of patients with aHUS.
