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 purpose of this study is to investigate how well the standard treatment (platinum-based doublet chemotherapy) in combination with denosumab works compared with the standard treatment alone in patients with a type of lung cancer called "non small cell lung cancer" (NSCLC) that has spread to other parts of the body.
Glioblastoma multiforme (GBM) is the most common malignant central nervous system (CNS) tumor in adulthood with a median survival of 12-16 months. The drastically shorted life expectancy, intellectual changes and rapid physical decline in those patients are devastating and do impose a profound chronic stress on patients and their families. There is extensive evidence that chronic stress can promote cancer growth and progression. In the setting of GBM patients, three major questions still have to be answered and will be analysed in this study: 1. Is there a prognostic significance of stress in patients with newly diagnosed GBM on treatment tolerance and (progression free) survival? 2. Can this stress be modulated by other factors, like stress of patients partners and patients physical activity, a known independent prognostic factor in recurrent glioma patients? 3. How is the longitudinal course of patients and partners stress and physical condition over the disease course and do they influence (progression free) survival? Answers to these questions will help to establish future projects studying non drug interventions in patients and patients partners to help improving clinical and tumor related outcome in patients with newly diagnosed GBM. The investigators hypothesize that chronic stress, specifically measured as a disruption of the diurnal cortisol rhythmicity, is an independent prognostic factor in patients with GBM. Furthermore, physical activity of patients and stress level in patients` partners may impact - as stress-modulating factors- on stress in patients and on their prognosis. Aiming at identifying stress-related prognostic factors as potential targets for novel treatment approaches, we propose, in a first step, a prospective multicenter cohort study: all patients with newly diagnosed GBM and good performance status (KPS ≥ 50%) who undergo standard treatment with combined radiochemotherapy with temozolomide (RCT) followed by 6 month of cyclic temozolomide, are eligible. In addition, one "partner", defined as a close person living in the same home or close daily contact to the patient, will be asked for inclusion.
Prospective clinical study to investigate the pathogenesis of Terson syndrome and the prognostic value of the CSF-biomarkers tau-protein and amyloid-β 40 and 42 in patients with aneurysmatic subarachnoid hemorrhage. Our two hypotheses are as follows: 1. The incidence of Terson syndrome correlates with the initial intracranial opening pressure (measured with extra ventricular drain) 2. The CSF-biomarkers correlate with the outcome assessed at discharge, 3-, 6- and 12-months postictally using Glasgow-Outcome-Scale-Extended (GOSE) and Euro-Qol-5 as well as with complications related to aneurysmatic subarachnoid hemorrhage such as cerebral vasospasm, delayed cerebral ischemia and re-bleed.
Objectives Primary objective: To determine if rivaroxaban (Xarelto) is feasible and safe for prevention of major complications in patients undergoing a mechanical aortic heart valve replace-ment. Secondary objectives: To identify the value of molecular markers suitable for monitoring of anticoagulation effectiveness of rivaroxaban and its correlation with transcranial Doppler emboli count in patients undergoing a mechanical aortic heart valve replacement. Design This is a prospective, open-label phase 2 pilot study with independent evaluation of all outcomes and a historical control group. Number of patients 30 in experimental group (patients in the center's registry database serve as control group). Main eligibility criteria All patients between 18 and 70 years old receiving a mechanical aortic valve replacement with a pre-operative left ventricular ejection fraction >/=35%. Interventions Experimental: Rivaroxaban 20mg p.o., once daily, for six months Historical control: Phenprocoumon (Marcoumar) p.o., once daily Outcomes Primary outcome: Composite outcome of prosthetic thrombus requiring reoperation/intervention, major bleeding, visceral ischemia, stroke, pulmonary embolism, myocardial infarction or death from any cause 180 days after intervention. Secondary outcomes: Each component of the composite outcome plus serious adverse events. Prosthetic thrombus requiring reoperation/intervention plus non-clinically relevant thrombi will be used as an additional safety outcome. Molecular markers suitable for monitoring the effectiveness of rivaroxaban.
The surgical management of long bone infections is often challenging. Adequate surgical debridement decreases the bacterial load, removes dead tissues, and gives a chance for the host immune system and antibiotics to arrest infection. Adequate debridement may leave a large bony defect. An appropriate management of the dead space is essential to arrest the disease, and for maintenance of the bone's integrity. The current strategy includes the use of antibiotic-loaded bone cement that can be used to sterilize and temporarily maintain the dead space. The cement are usually removed after 2 to 4 weeks and replaced with a cancellous graft harvested from the hip of the patient. CERAMENT™| G is a CE-marked resorbable ceramic bone graft substitute composed by calcium sulfate and calcium hydroxyapatite, intended to fill gaps and voids in the skeleton system and to promote bone healing. The antibiotic gentamicin is included in the ceramic to prevent colonization of gentamicin-sensible microorganisms in order to protect bone healing. The aim of this study is to investigate the device absorption and bone in-growth of CERAMENT™| G in a surgically revised bone infection. In addition, bone healing and infection non-recurrence will be evaluated during 12 months of follow-up. The investigators expect a treatment success of >90 % and that a similar bone healing will be obtained as with a standard two-stage surgical procedure. In addition, the investigators believe that the use of CERAMENT™| G will be of advantage for the patient as bone healing will be achieved with a one-stage surgical procedure (in combination with antibiotic therapy), instead of a two-stage procedure, thus decreasing potential surgery-related complications.
The aim of this study is to find the most agreeable and in the long term most efficient treatment for epistaxis.
Insulinoma: Insulinoma are rare, small insulin secreting neuroendocrine tumors. The only curative approach is the surgical excision. The preoperative detection remains a challenge. A non-invasive, highly sensitive tool in localizing the insulinomas would be appreciated in the preoperative work-up of these patients. To this aim Glucagon-like peptide-1 receptor (GLP-1R) imaging (Single Photon Emission Computer Tomography co-registered with a CT; SPECT/CT) could be a convenient tool. The possibly more sensitive approach of targeting GLP-1R using Positron emission tomography (PET/CT) methodology has not been investigated in patients so far.
Increasing evidence suggests pancreatic islet beta-cell regeneration occurs throughout the course of the disease in patients with type 1 diabetes. Therefore, decreased beta-cell mass in type 1 diabetes may be improved through inhibition of beta-cell destruction and stimulation of proliferation, even after prolonged duration of disease. Physical activity improves insulin secretion via unknown underlying mechanisms. We recently observed that Interleukin-6 induces glucagon like Peptide (GLP)-1 production and release from the islet alpha-cell and the intestinal L-cell. Furthermore, exercise induces release of Interleukin-6 from skeletal muscle resulting in elevated circulating Interleukin-6 levels. Therefore we hypothesize that exercise-induced Interleukin-6 promotes glucagon like peptide-1 secretion from the islet α-cell and the intestinal L-cell, thereby providing a mechanism how physical activity can help maintain and improve beta-cell function in patients with type 1 diabetes. This mechanism can be enhanced by concomitant dipeptidyl peptidase-IV inhibition. Physical activity is also known to enhance insulin sensitivity and to attenuate the immune system activity. Therefore by combining physical activity and dipeptidyl peptidase-IV inhibition we aim to allow for beta-cell regeneration in a interventional randomized open-label study.
The study was conducted to investigate the metabolism and mass balance of ACT-128800, and to identify the elimination pathways (metabolism and excretion) of ACT-128800 and compare them with the known metabolic profiles of ACT-128800 in animals.
Temporal dynamics of the EEG microstates show scale-free monofractal properties. This means that information is encoded in the same way at different scales. It may be postulated that these monofractal properties of the EEG microstate sequences constitute a necessary prerequisite of consciousness. We postulate that clinical variations of consciousness may also be linked to alterations of fractal properties of EEG microstates.
