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.
Evaluation of sensitivity after primary surgical treatment of digital nerve injuries with microsurgical epineural end-to-end neurorrhaphy alone or in combination with the fibrin glue Tisseel®
Alcohol use causes more overall harm than any other drug and is the seventh leading risk factor for both deaths and disability-adjusted life years. Alcohol use disorders (AUD) are among the most common and undertreated mental disorders in developed countries. Pharmacological and psychotherapeutic treatments only show limited efficacy and around 60% of the patients relapse in the short-term after withdrawal. Lysergic acid diethylamide (LSD) was investigated in numerous clinical trials during the 1950s and 1960s. Specifically, the use of LSD in the treatment of AUD was investigated extensively. A pooled analysis of six historical clinical trials demonstrated, that a single dose of LSD significantly reduced alcohol use at three and six months after LSD administration. However, these trials are limited by several factors, including the use of diagnostic standards that are no longer not up to date, single, high-dose treatment regimes, missing biological assessment for alcohol use, and no consequent assessment of blinding. Therefore, the present study aims to evaluate the safety and efficacy of LSD for the treatment of AUD and addresses the shortcomings of previous studies. The trial has a double-blind, active placebo-controlled, randomized, parallel design and will be conducted in specialized treatment centers for addictive disorders in Switzerland. The study will include 126 patients after withdrawal treatment and will primarily assess the efficacy of LSD for the treatment of AUD. Patients will be treated using a 1:1 allocation. Each arm will last 20 weeks and will comprise nine study visits without drug administration and two study days involving LSD or active placebo administration. In the first session, patients in the treatment group will receive a dose of 150 µg LSD, followed by another 150 µg or 250 µg LSD in the second session, which will take place approximately 4 weeks after the first session. The primary outcome is the mean of percent heavy drinking days after administration of two doses of LSD at 3 months follow-up. Additionally, the study will assess neurobiological mechanisms of action and several other measures.
Neck pain-associated disorders (NAD) and whiplash-associated disorders (WAD) are major health problems. NAD has a lifetime prevalence of 54%. Although the majority of patients recovers within the first three months, a minority develops persistent pain. WAD, in contrast, is reported less frequently, but patients are often suffering more badly. Patients with chronic symptoms represent a considerable burden in terms of pain, suffering, health care needs, and social costs. Findings on the natural course of NAD and WAD reflect the necessity to identify factors besides pain related to the persistence of symptoms. First, alterations of input and processing of multiple sensory modalities causing movement control impairment can result in persistent symptoms and affect the quality of life. Besides, findings of psychosocial factors predictive of pain outcomes support the growing body of research proposing a bidirectional relationship between somatic and psychosocial variables. In particular, there is a pressing need to investigate pain-related activity patterns, besides fear-avoidance behavior in NAD and WAD. Maladaptive activity pattern have an impact on on pain and disability in the long-term prognosis. Mt important, given the high prevalence of NAD and WAD, the cortical representation of the cervical spine has not yet been investigated and, reports on neuroplasticity remain scarce. These shortcomings should be addressed to provide evidence for the temporal aspect of neuroplasticity and its involvement in pain persistence. Hypotheses: We hypothesize I. that impaired sensorimotor abilities, mental health at baseline increase pain intensity and disability during measurement. II. that maladaptive pain-related activity patterns avoidance and overactivity at baseline are prognostic factors for pain persistence and disability. III. that the WAD cohort shows more depression, anxiety and stress compared to the NAD cohort.
The main aim of this study is to investigate the effects of cone-modulated light emitted from a visual display on human circadian physiology and cognitive performance in the evening.
The clinical efficacy of tralokinumab has been demonstrated in the treatment of AD; its MOA however remains insufficiently understood. A better understanding of the mechanisms underlying the clinical effects of tralokinumab would be of great clinical benefit since it may ultimately help us to identify more precisely candidate patients who may benefit from a therapy with tralokinumab.
The purpose of the study is to evaluate the validity of PROMS after reconstructive surgery or amputation in the leg region. In this context, the German version of the LIMB-Q, a questionnaire-based "Patient-reported outcome measurement" (PROM), will be validated for the German-speaking region and any necessary cultural adaptations will be made for the future use of the questionnaire. In addition, the aim is to establish a context between the LIMB-Q as a PROM and clinical outcome measurements (Maryland Foot Score, American Orthopedic Foot and Ankle Society Score).
Aging is associated with an increased inflammation named "inflammageing" and with an altered immune response. Different mechanisms have been proposed to explain the phenomenon of inflammageing and increased oxidative stress: deficiencies in essential amino acids, and some micronutrients have an important impact and may induce immune cell dysregulation. Mitochondrial dysfunction may explain the complex relationship between malnutrition sarcopenia, immune dysfunction and aging. Therefore, a personalized nutritional strategy aiming to improve mitochondrial function, decrease oxidative stress, down-regulate inflammation and restore immunity appears to be a logical approach in order to treat malnutrition and its biological and clinical consequences. MIMOSA will investigate the role of nutritional supplements in rescuing altered mitochondrial function and redox state imbalance.
The aim of this cross-sectional online study is to investigate the association between regular feeding behavior and stress, sleep as well as anxiety and depressive symptoms in healthy subjects.
Objectives: To perform pilot study using unilateral transcutaneous electrical stimulation (TENS) on thegenital nerves (dorsal nerve penis and cavernous nerves) for improving of the intracorpereal pressure and full penil erection in men after exclusion neurogenic, endrogenic and earteriogenic disorders. The investigators hypothesize that this therapy will be effective at improving erectile dysfunction (ED). Material and methods: The study will comprised 20 patients with ED randomized in two groups. Two adhesive skin electrodes are placed, one at the root of the penis and near the pubic symphysis as a cathode, and a second 2-3cm lateral to the penis. Stimulation is delivered for 30 min at the maximal tolerable stimulation amplitude at 210μs pulse width and in one group with a pulse rate at 20Hz, the second group at 60Hz. The penile tumescence and rigidity observed during stimulation are recorded in both groups of patients. Erection Harness Score (EHS) and Quality of Erection Questionnaire (QEQ) are assessed at baseline, immediately after stimulation and 2 weeks after stimulation.
WHO: 32 participants with executive deficits related to a stroke, able to engage in moderate physical activity. WHY: Around one third of stroke patients suffer from cognitive deficits in the long term, which have a detrimental impact on everyday personal and professional life. The purpose of this study is to evaluate two sets of computerized exercises combining cognitive and physical effort to see if they can improve executive function. WHAT: Study participants first undergo cognitive and physical assessments. Additional questionnaires will assess mood, everyday life cognition, function and quality. This will be followed by a 6 week training period with 3 training sessions a week. The effect of the cognitive and physical training will be measured in a post-training evaluation session. Six months after completion of the training, the study will evaluate cognitive and physical abilities of participants to study long-term effects of the respective training program. WHERE: Both the evaluation and the training sessions will be conducted on the premises of the Centre Hospitalier Universitaire Vaudoise (Pavillon 4, Avenue de Beaumont, 1005 Lausanne, Switzerland)
