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.
Background: High- and low-flux dialysis membranes made of different materials may correlate with various hemodynamic tolerance profiles. This study aims to investigate hemodynamic response and incidence of hypotensive episodes by comparing some of the most commonly used high- and low-flux dialyzers. Methodology: The study was designed as an open label, randomized, cross-over investigation, including 25 patients undergoing chronic hemodialysis. Four polysulfone dialyzers of 1.8 m2, A (Revaclear, Gambro), B (Helixone high flux, Fresenius), C (Xevonta, BBraun) and D (Helixone low flux, Fresenius), were compared with each other. The hemodynamic profile was assessed with a non-invasive technique and patients were asked to provide tolerance feedback through a questionnaire.
The purpose of this study is to demonstrate that treatment with etelcalcetide (AMG 416) is not inferior to treatment with cinacalcet for lowering serum parathyroid hormone (PTH) levels by > 30% from baseline among patients with chronic kidney disease (CKD) and secondary hyperparathyroidism (SHPT) who require management with hemodialysis.
The present research aims at examining the effectiveness of a specific set of therapist relational interventions and attitudes, called the Motive-Oriented Therapeutic Relationship (MOTR), based on Plan Analysis (Caspar, 2007) in the early-phase treatment of patients diagnosed with Borderline Personality Disorder. The investigators intend to include N = 80 outpatients diagnosed with Borderline Personality Disorder, consulting at the Outpatient Personality Disorder Program of the Karl Jaspers Clinical Unit, in collaboration with the Institute of Psychotherapy, at the Department of Psychiatry-CHUV, University of Lausanne and in collaboration with the University of Berne, Switzerland. Patients are assigned by chance to two treatment conditions 1) Control condition (General Psychiatric Management; Gunderson & Links, 2008) and 2) MOTR-condition. The investigators hypothesize better results in the MOTR-condition, as compared to the control condition in terms of symptom reduction pre-post. The conduct of the study represents a significant contribution to the understanding and enhancement of relationship aspects in the treatment of patients diagnosed with Borderline Personality Disorder which may be of potential benefit for these patients.
The main objectives of this large phase IIb/III paediatric study are to assess the efficacy and safety of dabigatran etexilate relative to standard of care and to document the appropriateness of the proposed dabigatran etexilate dosing algorithm for use in patients from birth to less than 18 years of age.
Within few years the peritoneal membrane of adult peritoneal dialysis (PD) patients undergoes substantial morphological transformation, including progressive fibrosis, vasculopathy and neoangiogenesis. Ultrafiltration capacity steadily declines and ultimately results in PD failure. In children, peritoneal biopsies demonstrating PD associated alterations have not yet been obtained. They, however, should be particularly informative, since secondary tissue and vascular pathology related to ageing or diabetes is absent. An international, prospective peritoneal membrane biopsy study in children on PD will therefore be performed. Biopsies will be obtained at time of PD catheter insertion, on occasion of intercurrent abdominal surgery (e.g. hernia repair, catheter exchange) and at time of renal transplantation. Quantitative histomorphometry and tissue protein expression analyses will be correlated with time integrated PD treatment modalities and functional characteristics as well as inflammatory and cardiovascular comorbidity surrogate parameter. Blood will be obtained during clinical routine sampling. Biopsies will be obtained during clinically indicated operations, without substantially increasing operation time and associated surgical risks. The detailed histomorphometry of the PD membrane will give additional information, potentially impacting on the individual PD regime. 3/2018: The analyses of the pediatric PD biopsy demonstrated early and major transformation of the peritoneal membrane with neutral pH low GDP fluids, and significant vasculopathy already in children with CKD stage 5, further progressing with PD. The underlying mechanisms are partly understood, only. In view of these major findings and the numerous open questions, collection of biosamples will be continued in children and also in adult PD patients. The following questions will be addressed: Molecular counterparts of peritoneal semi-permeability, solute and water transport (beyond AQP1), pathomechanisms and molecular and functional impact of peritoneal transformation with low and high GDP fluids, and the respective pathomechanisms and molecular and functional impact of vascular disease in CKD and with different PD fluids. The impact of renal transplantation following PD will be assessed in a subgroup of patients with tenckhoff catheter removal several weeks after transplantation and a functioning graft.
The study is to assess whether the influenza vaccine Inflexal V for season 2013/2014 fulfills the EMA requirements for re-registration of influenza vaccines.
The best way to combine a loco-regional procedure such as chemoembolisation or radioembolization combined with an anti-angiogenic drug is not clear. This phase I trial aims to establish, first, the tolerability of the combination of liver radioembolization with SirSpheres® and sorafenib in uveal melanoma patients with liver metastasis studying different schedules of administration of sorafenib after and before radioembolization. Secondly, we aim to evaluate angiogenic markers modifications during these different schedules, either in the serum or radiologicaly. Dose of Sorafenib will be 400 mg BID and the timing of introduction will differ for one cohort to the other, given after the radioembolization for initials cohorts and finally, before and concomitantly to radioembolization for the last cohort.
This study is aimed at assessing how Roux-en-Y gastric bypass (RYGP) impacts on energy and nutrients' intake, energy expenditure, and nutritional status in obese patients. It will try quantitate energy and protein balance after RYGP, and to identify how RYGP effects the intake of various common dietary protein sources 16 female patients with BMI > 40 kg/m2 and on a waiting list for bariatric surgery will be included. The following measurements will be performed before, and 1, 3, 6, 12, and 36 months after RYGP - body weight - body composition (bio impedancemetry) - basal metabolic rate (open circuit indirect calorimetry) - 24-hour urinary urea excretion - fasting blood chemistry - energy and macronutrient's intake (3-day dietary recall)
Background: The presence of orthostatic hypotension (OH) as a consequence of blood volume redistribution during verticalisation in persons with spinal cord injury (SCI) is a common condition. Aims: To investigate the impact of three different types of electric stimulation (ES) (ES of the abdominal muscles versus ES of lower limb muscles versus simultaneously ES of abdominal and lower limb muscles versus control) on blood pressure stabilization and verticalisation-degrees between 0° and 70°. The hypothesis is, that the ES-induced contractions of the muscles cause a stabilisation respectively an increase of the blood pressure during the tilt-table test. Subjects: 20 Women and men, at least 18 years of age, following an acute and traumatic SCI, with a lesion level above T6, an American Spinal Injury Association (AIS) Impairment Scale A,B or C and a diagnosis of OH (by tilt table test) were eligible for the study. Methods: Each patient underwent randomly three different types of ES sessions while being positioned on a tilt-table. The following sessions were planned: A) ES of the abdominal muscles B) ES of the lower limb muscles C) Combination of A and B D) Control session (=diagnostic session) Study type: Intervention Design: Prospective interventional study
Participants being evaluated for suspected or known Coronary artery Disease (CAD) based on signs and/or symptoms, will be invited to participate in the study. The duration for a participant in the study may range from 2 days to 4-6 weeks. One to four visits to the study doctor will be required. This study will investigate the diagnostic results of gadobutrol-enhanced Cardiac Magnetic Resonance Imaging (CMRI) images regarding the detection (sensitivity) and exclusion (specificity) of coronary artery disease utilizing a uniform image acquisition software. The CMR images will be tested either against the results from routine clinical Coronary Angiography (CA) or those from Computed Tomography Angiography (CTA), which is used as the standard of reference. The CA/CTA may have been performed up to 4 weeks prior to enrollment or be scheduled up to 4/6 weeks after the study. CMRI and CA/CTA images will be collected for an independent image review (blinded read).
