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 aim of this prospective single-center study is to evaluate sympathetic nervous system directly measured by microneurography, 24-hour blood pressure, endothelial function, vascular compliance, quality of life and platelet adhesion in patients with sleep apnea syndrome (defined by a complaint of excessive daytime sleepiness, an Epworth sleepiness score>8[10], and an apnea/hypopnea index (AHI>15/h) before and after catheter-based radiofrequency ablation of renal nerve. If the selected patients are treated with CPAP, this therapy should be stable during the whole study time. Primary and secondary end-point will be measured before and 1, 3, 6 and 12 months after renal sympathetic denervation.
Huntington's disease (HD) is an incurable and fatal disorder characterised by progressive degeneration of the basal ganglia and the cerebral cortex. Contrary to earlier thinking, HD is associated with abnormalities in peripheral tissues which might even contribute to brain pathology including muscle wasting, mitochondrial abnormalities, and impaired muscle energy metabolism. Mitochondrial impairment and muscle atrophy in human HD patients and murine models of HD are associated with altered expression of PGC-1a, a transcriptional cofactor that seems to regulate many, if not all of the adaptations of muscle fibres to chronic endurance training, and induces improved exercise performance and increased peak oxygen uptake. We aim at investigating whether endurance exercise has the capability of stabilizing and / or reversing PGC-1a dependent alterations of muscle function and structure in HD patients, and whether muscle training ameliorates musculoskeletal and cardiovascular function, as well as motor and cognitive symptoms in HD patients.
the purpose of the study is to investigate whether arginine infusion is a new tool to differentiate patients with diabetes insipidus, primary polydipsia and healthy subjects.
The purpose of this study is to characterize the acute psychological, physiological, endocrine, and pharmacokinetic, as well as long-term psychological effects of LSD in humans.
The aims of the APRICOT study are: - To establish the incidence of severe critical events in children undergoing anesthesia in Europe. - To describe the differences in paediatric anaesthesia practice throughout Europe. - To study the potential impact of this variability on the occurrence of severe critical events (Laryngospasm, Bronchospasm, Pulmonary aspiration, Drug error, Anaphylaxis, Cardiovascular instability, Neurological damage, Perianaesthetic cardiac arrest and postanaesthetic Stridor).
Patients with an edentulous mandible restored with implants who have participated in the core study CR 04/07 will be recruited for this extension study. No further interventions will be made for this extension study other than a clinical follow-up examination and questionnaires. Patients will not receive an investigational treatment in this study. Patients will be followed at 5 to 10 years from the date of the original implant loading
The purpose of this study is the validation of the Brief Michigan Hand Questionnaire by patient with Morbus Dupuytren and to build up a register.
Adult recipients of cochlear implants (CI) generally loose interest in listening to music. This may be due to the rather limited spectral resolution of CI. However, child CI-recipients, if offered the opportunity, like to listen to music. They participate actively in musical acitivities, such as singing, dancing or playing an instrument. Thus, there seems to be a fundamental difference in the music perception of people who receive CI as child or as adult. This study assesses music perception skills of child, teen and adult cochlear implant recipients in settings with simple tone sequences and in a more complex, melodious context.
Pathogens of ventilator-associated pneumonia (VAP) come from colonizers of the trachea. The hypothesis of the investigators is that during the first days of intubation, independently of the use of antibiotics, there is a change in the oro-pharyngeal flora leading to the selection of one pathogen in the trachea, that will finally be the cause of VAP. The investigators designed a prospective study including 300 patients intubated for more than 3 days, with daily analysis of oro-pharyngeal juice and tracheal aspirate by culture and metagenomics, in order to determine if this microbiological surveillance permits: 1. To predict a high risk to develop a VAP in the next 48h and even to predict its agent 2. To better understand the development of VAP by studying the evolution of the "respiratory flora" in the context of intubation
The objective of this study is to examine gastric emptying and satiety hormones after oral glucose stimulation in 2 different concentrations in normal-weight and obese patients.
