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.
In this study the investigators want to investigate to what extent the application of an artificial bone flape (space flap) influences the success of a decompressive craniectomy. In all participants, a space flap is placed immediately after removal of the skull cap. In a second operation, after 1-3 months, an operation is performed, in which the stored own skull bone is re-inserted. The artificial bone cover is removed at this point.
Lysergic acid diethylamide (LSD) is used as recreational substance and as a research substance to study the mind. Recreationally, LSD is typically used in the form of "blotters" containing LSD tartrate. In research, both LSD base (LSD alone) or LSD salt in the form of LSD tartrate are used. The oral bioavailability of LSD is not known and LSD alone and LSD as salt have never been directly compared regarding their equivalence of plasma concentrations and effects. Because different forms of LSD are used in research it is important to know their difference or equivalence for correct dosing of LSD. The present study will compare equivalent doses of LSD base in ethanol orally, LSD tartrate in water administered orally, LSD base in an orodispersible film administered orally and LSD tartrate in water administered intravenously, as well as a placebo using a double-blind, randomized, counterballanced cross-over design in healthy participants.
The CARE-HK in HF is a registry study based on the hypothesis that adherence to guidelines is associated with improved real-world outcomes for heart failure (HF) patients. For the purpose of this study, adherence to guidelines is defined as adherence to RAASi treatment recommendations, according to the AHA/ACC and ESC guidelines. Objectives relating to patiromer effectiveness will only be evaluated if a sufficient number of patients are available. The study aims to evaluate in patients at high risk of hyperkalaemia; patients treated with ACEi/ARB/ARNi, and either treated with or candidates for treatment with MRA.
Improving Low ASPECTS Stroke Thromectomy (I-LAST) is an academic, independent, prospective, multicenter, observational registry study. Consecutive patients treated with endovascular stroke treatment will be enrolled in German stroke centers. Patients receive regular care and data will be collected as part of clinical routine. Baseline clinical and procedural information as well clinical follow-up information during in-hospital stay, and up to 90 days of stroke onset are collected. Data collected include demographics, National Institute of Health Stroke Scale (NIHSS) on admission, pre-treatment ASPECTS, information on timing and success of interventional treatment, procedural complications, intracranial hemorrhage, and functional outcome. Advanced imaging biomarkers will be tested and validated aiming to improve treatment selection and outcome prediction of patients presenting with extensive baseline infarction.
Patients who were surgically treated with ACL reconstruction at a single clinic between 2013 and 2018 will be approached by a questionnaire regarding their return to sport after surgery. Questions will focus on the timepoint of the return, subsequent injuries, and the impact of the initial injury on the life of the patients. In addition, existing clinical data from the baseline visit and from the follow-up visits offered routinely to the patient will be used.
Walking difficulties, mobility decline and falls are prevalent among older adults. The incidence of each of these increases with age and the presence of each can negatively affect the quality of life in older adults. The purpose of this prospective clinical trial is to evaluate the efficacy of the Power Centering for Seniors multimodal, twice weekly, 12-week group intervention program to improve the mobility and quality of life in older, community-dwelling adults.
When diagnosing chronic cough (cough lasting longer than 8 weeks), the physician nowadays very often relies on the patient's narrative and description. In our research project we want to find out whether a cough detector can continuously and reliably record the cough, how the user-friendliness of the cough detector is assessed and whether this continuous recording can support the physician in his diagnosis.
This study will evaluate real-world outcomes for the SAPIEN 3 Ultra Transcatheter Heart Valve System in transcatheter aortic valve implantation centres that are implementing minimalist periprocedural practices and facilitating early discharge home.
The precision of the novel diagnostic near-infrared spectroscopy (NIRS) device for the measurement of tissue oxygenation and hemoglobin concentration (OxyPrem) is assessed by repeated measurements. The accuracy of OxyPrem is assessed by comparing the measurement data to those acquired simultaneously by established NIRS devices and standard clinical monitoring devices. In substudy 1, healthy adult subjects are enrolled, in substudy 2, measurements are conducted on preterm neonates.
A Prospective Randomized, Multi-center, International, Single-blind, Clinical trial compared the Selution DEB strategy versus DES strategy.
