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 experience of pain is more than the conscious perception of nociceptive signals. Emotional and motivational aspects accompany pain, leading to its aversiveness and motivation for avoidance. In chronic pain, a negative hedonic shift has been proposed that is characterized by disproportionally increased emotional-motivational compared to sensory-discriminative pain responses. Such a negative hedonic shift is, for example, mirrored in very high comorbidity rates of chronic pain and affective disorders such as depression and anxiety. The aim of this study is to develop methods that allow the differentiation of sensory-discriminative and emotional-motivational pain response and to characterize mechanisms of the negative hedonic shift.
This study aims at investigating the role of low-gamma activity in phonemic encoding and its implication in dyslexia. Indeed, a phonological deficit, i.e. a difficulty in perceiving the sounds of speech, is strongly suspected in dyslexia but has never been conclusively associated with a specific underlying mechanism. The study employs transcranial alternating current stimulation in adults with and without dyslexia to exploit the effect of the stimulation on phonemic processing and neural activity measured with electroencephalography. In doing so, it would be possible to establishing a causal link between gamma oscillations and the phonological deficit in dyslexia.
With aging the amount of slow wave sleep decreases drastically and this disruption is markedly exaggerated in older adults suffering from mild cognitive impairment and Alzheimer's disease. Critically, the disruption of slow wave sleep and cognitive decline seem bidirectionally linked forming a vicious cycle. In the long run, improving slow wave sleep might be a useful intervention tool to delay the onset of cognitive decline. The present study aims at improving slow wave sleep and memory functions through a closed-loop acoustic stimulation approach. A closed-loop algorithm is used that detects slow waves in the electroencephalogram and is programmed to present short tones (50 ms) in the rhythm of these waves. This procedure has shown to boost both slow wave sleep as well as memory performance, mainly in young adults and when applied for one night. Here, the investigators apply tones via multiple consecutive nights and assess memory performance during this 3-night intervention.
Sleep is ubiquitous in animals and humans, and disruptions are of high clinical importance. Still, the neural basis of sleep perception is insufficiently understood, which limits the development of new treatments. The current project is designed to further contribute to the understanding of the neural basis of sleep perception and to the development of innovative treatments for disrupted sleep (insomnia).
Mauriac syndrome (MS) is an entity of individuals combining poorly controlled diabetes mellitus type 1, short stature and glycogenic hepatopathy. Thus, the functional significance of Mauriac syndrome for glucose metabolism remains disputed, and whether genetic defects in glycogen metabolism contribute to glycogenic hepatopathy in MS remains to be clarified.Coupling the genetic analysis of targeted genes involved in glucose regulation with a dynamic exploration will eventually determine if a genetic abnormality leads to the disease and explains the nature of the phenotype.
This randomized controlled study aims to investigate whether, during a painful medical procedure in an emergency department (ED), the diffusion of a virtual environment through a virtual reality (VR) headset worn by the patient has a greater impact on the patient's pain and anxiety levels than the diffusion of an identical environment through a computer screen. The study design allows differentiating the impact of the medium from that of the media. The feeling of telepresence of patients in both groups and its association with the impact of the medium will also be investigated. In addition, this study aims to explore whether the wearing of VR headphones is considered comfortable and acceptable by patients.
Far infrared light (FIR, 5.6-1000 µm) penetrates our skin and reaches the underlying tissue up to 4 cm and promotes widening of the blood vessels (vasodilation). This results in increased blood flow in the tissue under the skin, without heating up the skin itself. Increased blood flow allows more oxygen to reach the muscles and more metabolic waste products to be transported away from the muscles. Studies assessing clothing containing an FDA approved ceramic particles covered yarn that reflect FIR light showed delayed onset muscle pain decreased and a reduction in inflammatory markers in professional athletes. The aim of this study is to investigate the effect of far infrared reflecting sleepwear on night-time recovery and Sleep in a broader population, namely physically active adults (non-professional).
High and Very High Risk cardiovascular patient journeys seems to vary from country to country, and current understanding of the process is incomplete. This real-life observational study which documents meaningful patient journey-related parameters can be expected to provide meaningful insight into the care process, country-by-country.
The iLIVE project involves a cohort study in which patients with an estimated life expectancy of six months or less are followed until they die. In total, the investigators will include 2200 patients in 11 countries, i.e. 200 per country. The primary outcome for the cohort study is a descriptive assessment of the concerns, expectations and preferences around dying and end-of-life care of patients and their relatives, in different settings and cultures..
The statistical risk of intrastent stenosis has fallen considerably with the emergence of latest generation coated stents (drug-eluting stents: DES). The number and clinical lifespan of stents implanted over the last twenty-five years, however, explain the fact that restenosis remains a not unusual clinical problem which is expressed as a recurrence of angina or of an acute coronary syndrome (ACS). The mechanisms involved in this restenosis are multifactorial in nature and differ depending on the type of stent and the time since the restenosis occurred. In symptomatic stent restenosis (angina or acute coronary syndrome), a further angioplasty is usually required, occasionally on an emergency basis. Coronary angiography is often not capable of explaining the mechanical causes of this complication. Optical coherence tomography (OCT), a high-resolution endocoronary imaging technique can assist in the understanding of the mechanism of restenosis and guide treatment. OCT during angiography provides a detailed analysis of the stents and potential complications: the presence of neoatherosclerosis with or without plaque rupture, intimal hyperplasia, stent under-deployment, stent fracture and distal or proximal progression of the atherosclerosis. The investigators propose a prospective, multicentre study of all cases of intrastent restenosis, examined by angiography, causing clinical features involving stable angina and acute coronary syndrome. The coronary artery involved will be routinely studied by OCT for a mechanical cause of the intrastent restenosis. The routine use of intrastent OCT may assist in the understanding of causes of restenosis and in the decision on appropriate treatment. There are several possible treatments for restenosis, including balloon angioplasty, coated balloon angioplasty, stenting or aorto-coronary bypass graft surgery.
