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.
The popliteal plexus block has been described as an alternative analgesic postoperative pain treatment for total knee arthroplasty. It consists of injecting local anaeshetics inside the distal end of the adductor canal close to the adductor hiatus, adjacent to the femoral artery, between the medial vastus muscle and the adductor magnus muscle, in order to anesthetize the popliteal plexus. However, the analgesic efficacy has never been demonstrated in a randomized controlled trial. Therefore the objective of this study is to investigate the analgesic benefit of this block combined with a continuous femoral nerve block, on patients scheduled for total knee athroplasty.
Patients with severe CAR-T cell associated cytokine release syndrome (CRS) (defined as vasopressor dependent) will be treated with standard of care (SOC) + cytokine adsorption (6hourly for 24 hrs). Primary endpoint is the change in plasma IL-6 between 0 and 24 hrs.
We implement a prospective, randomized, unblinded, non-inferiority trial regarding the duration of systemic, targeted antibiotic therapy after the first surgical debridement for spine infection; randomizing 1:1 between 1. Six and twelve weeks of antibiotic therapy if there is an implant left in place 2. Three and six weeks of antibiotic therapy if there is no implant left
BERING-MELANOMA - designed as a prospective, longitudinal, non-interventional study - investigates real-world effectiveness, quality of life, safety and tolerability of encorafenib plus binimetinib in unresectable advanced or metastatic BRAF(Rapidly Accelerated Fibrosarcoma isoform B)-V600-mutant malignant melanoma after commercial availability of these two products in Germany, Austria and Switzerland. The study focusses on the documentation of the first and second line setting (i.e. after one line of prior checkpoint inhibition) by documenting patients treated according to the SmPC (Summary of Product Characteristics).
Patients with subarachnoid hemorrhage are prone to suffer from dysnatriemia. Evidence shows that hyponatriemia is associated with increased incidence of vasospasm, brain swelling and mortality in these patients. Patients with subarachnoid hemorrhage often require large amounts of iv fluids in order to maintain euvolemia and support cardiocirculatory function. Prior evidence shows that the type of infusion fluid significantly influences blood sodium content. Hence, this study evaluated whether the sodium content of the infusion solution impacts mortality and morbidity in patients with subarachnoid hemorrhage.
Primary objectives: - Randomization R1, all patients eligible: To examine, whether the cumulative incidence of relapses with involvement of the CNS (CNS relapse, pCICR) can be decreased by a modified induction therapy including dexamethasone (experimental arm) instead of prednisone (standard arm) - Randomization R2, only patients with high risk LBL eligible: to examine, whether the probability of event-free survival (pEFS) in these patients can be improved by receiving an intensified treatment arm versus a standard treatment arm (as used in the EURO-LB 02)
To compare presence and kinetics of Mycoplasma pneumoniae (Mp)-specific immunoglobulin (Ig) M antibody-secreting cells (ASCs) with Mp DNA and Mp-specific IgM antibodies in patients with community-acquired pneumonia (CAP) of the KIDS-STEP study.
This study contributes to fundamental research investigating the role of the articulatory-motor integration and cerebro-acoustic coherence in speech comprehension. In a series of experiments non-invasive brain stimulation (NIBS) techniques including transcranial electric stimulation with alternating current waveforms (tACS) and transcranial magnetic stimulation (TMS) will be applied to the left ventral motor cortex (vMC) to test the contribution of this area to speech comprehension under challenging listening situations. As long as the exclusion criteria for TMS and tACS are strictly considered, only very minimal risks and no long-term effects are expected. There are no known risks associated with NIBS and pregnancy; however, since risks cannot be completely excluded, pregnant women will be excluded from participation. If a female participant is uncertain whether she is pregnant, she will be provided with a pregnancy test at no cost.
Reperfusion is the main goal of early medical interventions after stroke, such as thrombolysis and thrombectomy. Recanalization works only if applied early - the earlier the better, but with a statistical cutoff of 4.5 hours where risk of hemorrhage outweighs the benefit. Recently, this cutoff has been put into perspective using standardized perfusion measurements by magnetic resonance imaging (MRI) or computed tomography (CT). Two trials have shown that revascularization is beneficial up to 24 hours after stroke onset if patient selection is based on perfusion imaging. This suggests interindividual differences in the temporal evolution of an infarction. One explanation for interindividual differences is the variability of the collateral blood supply to the brain, which in turn can maintain different perfusion pressures around the infarct core, also called the penumbra region. Insufficient recruitment of these collateral pathways is an independent negative predictor of poor outcome; the insufficiency may in part be explained by insufficient dilatation of arterioles ("low dilator reserve"). So far, interventions to improve collateral perfusion, e.g., induced hypertension, have not demonstrated effectiveness, likely because our understanding of collateral perfusion, demand-dependent dilatation of arteries (cerebrovascular reserve, CVR) and their effect on microcirculation is insufficient. Functional recovery after a brain lesion is based on plasticity. Plasticity involves the creation of new synapses, fibers (axons and dendrites) and lasting modification to synaptic strength as well as the formation and migration of new neurons. In the cortex surrounding an infarct, plasticity is facilitated by ischemia via modification of gene expression, i.e. a certain time window after stroke, and is stimulated by activity and training. Tissue microcirculatory status and perfusion surrounding the stroke lesion may play a role in the formation of this plasticity. The investigators will analyze the contributions of pre-existing vascular networks, the impact of stroke-affected vessels, timing and degree of recanalization success, brain excitability, and short-term intra-cortical inhibition to better understand how these factors relate to functional recovery after stroke.
The primary objective of this study is to confirm the safety and clinical effectiveness of the Genio™ system, used according to its instructions for use, in moderate to severe Obstructive Sleep Apnea (OSA) adult patients over a period of 3 years post-surgery.
