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.
Primary objective: To determine whether pregnancy increases the risk of recurrent CeAD and delayed stroke in women with prior CeAD based on long-term data. Methods: Multicentric, observational case-control study based on pooled individual patient data from several stroke centers. Primary endpoint: Primary composite outcome measure includes the following outcomes: (i) occurrence of recurrent CeAD, (ii) occurrence of ischemic or hemorrhagic stroke, (iii) death.
Established gait assessments for subjects with spinal cord injury (SCI) (6MWT, 10MWT, TUG, SCIM III and WISCI II) are widely used in the clinical and research setting. So far, no valid measurement exists that assesses the patients' perspective of walking ability in SCI. As there is the 12-item Multiple Sclerosis Walking Scale (12-WS) to assess the patients' perspective on gait ability in patients with multiple sclerosis, it is hypothesized that the 12-WS would also be a valid instrument for subjects with incomplete SCI. The main goal of this study is to collect data from clinical gait assessments in subjects with spinal lesions and to demonstrate that the 12-WS is a valid and reliable patient-reported outcome measurement for individuals with incomplete spinal cord injury.
The goal of this observational study is to compare a novel dermal substitute to a the current standard procedure in the treatment of full thickness skin defects. The main questions aim to answer are: • Is the skin elasticity treated with the novel dermal substitute better than the skin elasticity treated with the current standard procedure Participants skin elasticity will be measured by Cutometer® MPA-580 assessment.
The few reports on effects of psychedelic substances on cerebral metabolic rate (CMRglc) indicate increases (psilocybin; human FDG-PET) or decreases (LSD, rat autoradiography; 5-MeO-DMT rat autoradiography). There are no reports of effects of DMT and/or harmine on cerebral energy metabolism. The primary objective of this study is thus to assess acute cerebrometabolic effects of harmine/DMT in healthy volunteers using quantitative FDG-PET, that is, to measure CMRglc before and after simultaneous treatment with an oral harmine and DMT formulation developed (and already applied) by the investigators' project partners at the University of Zurich. As a secondary objective, the researchers aim to correlate the time-dependent effects on CMRglc as assessed in the PET images with the time-dependent self-reported intensity of participants' psychedelic experience.
The goal of this clinical trial is to investigate the use of virtual reality therapy in dialysis patients. The main question it aims to answer is: Does virtual reality improve symptom burden in dialysis patients and improve their mental wellbeing? Over a period of one month, one virtual reality therapy session of 30 minutes will be performed during each regular hemodialysis session. Since we will conduct a monocentric, crossover randomized controlled trial, the participants act as their own control group.
This project will study the effects of a major reorganization of psychiatric inpatient wards. This reorganization will affect many aspects of day-to-day work, with the aim of improving the individualization of care, the integration of relatives and the participation of the patients in treatment planning. This new organization will initially involve a first pilot ward, before being extended to other wards. The aim of this project is to understand whether this new organization has positive effects on the use of coercive measures, the average length of stay, the improvement in patients' clinical condition, as well as on patient satisfaction, their perception of coercion, the wards' atmosphere on the unit and patients' personal recovery. All patients admitted to three wards of the Division of adult psychiatry of the Geneva University Hospital aged 18 and over, with a good knowledge of French and being treated for any type of diagnosis except dementia, are invited to take part in the study. They will be assessed at discharge regarding the selected outcomes. The study will last 18 months: during the first 9 months, the new model will be applied on the pilot ward, and the wo other wards will serve as comparison wards. After 9 months, the model will also be applied to these other two wards.
Treatment of rectal cancer by standard neoadjuvant chemoradiotherapy protocols leads to a complete response in about 15% of patients, or even a higher fraction if radiotherapy is followed by an Oxaliplatin based chemotherapy as published recently. If patient presents with a (near) complete response at the time of restaging after neoadjuvant treatment, an organ preservation strategy can be an alternative treatment to low anterior resection or abdominoperineal excision of the rectum. An organ preserving strategy is an ideal option for patients that are too frail for a major oncological resection. Furthermore, organ preservation is increasingly an option for a broader spectrum of patients as there is growing evidence that it allows to avoid surgical risks, including major dysfunction of the urinary, sexual and anorectal function at equivalent oncological outcomes. Studies investigating organ preserving rectal cancer treatment can broadly be divided into two categories. The first option is a planned local resection of the remaining scar at the site of the tumor after chemoradiotherapy. This can be achieved by direct transanal resection in very low tumors or by an endoscopic procedure as TEM (transanal endoscopic microsurgery) or TAMIS (trans-anal minimally invasive surgery). The advantage of this approach is the resulting pathological diagnosis which can confirm the complete response microscopically or indicate if there is remnant tumor tissue left and whether this is completely removed. However, local resection might have an additional negative functional impact and cumulate with function impairment from chemoradiotherapy. Alternatively, patients after complete clinical response can directly enter a surveillance programme without excision of the remaining scar after neoadjuvant treatment. This strategy provides less certainty about the complete regression of the primary tumor, but allows a treatment completely without surgical interventions and might lead to an even better functional outcome compared to patients undergoing local excision. There is good evidence that the influence of chemoradiotherapy on anorectal and genitourinary function is relevant. However there is lack of good quality data how much local excision adds to this impairment on the long run. In this study the investigator aims to compare functional outcomes and subjective treatment satisfaction in patients undergoing organ preserving treatment for rectal cancer with and without local resection after chemoradiotherapy. This data will help patients and healthcare personal to choose between these treatment options in the future, knowing the difference in functional outcome between the groups. As this is an observational study, there will not be any influence on treatment decisions for the included subjects. Clinical data will be collected by questionnaires and compared between the two cohorts, which is in line with a risk category A according to HRO (Human Research Ordinance).
Oxytocin has been proposed as a neuroendocrine mechanism that may mediate the relationship between dog ownership and positive health outcomes and be linked to human-dog interactions and is thought to be a mechanism of interspecies bonding. While the role of oxytocin in human bonding behaviours and social behaviour, in general, is becoming well-established the role of oxytocin in human-animal interaction and Animal-Assisted Interventions (AAI) remains unclear. This research gap calls for more high-quality research investigating this possible neuroendocrine underlying mechanism to advance knowledge about AAI. If oxytocin indeed might be involved in interspecies bonding, intranasally administered oxytocin should not only enhance trust toward a human but also towards a dog.
The present study consists of 3 projects in total and aims to investigate the (neuro-) psychological patterns from suicidal ideation to suicidal behavior as well as the effects and feasibility of ASSIP Home Treatment. The overall aim of project 1 is to determine (neuro-) psychological differences between suicide attempters, suicide ideators, a clinical control group, and healthy controls. Study participants in project 1 will participate in a one-time (neuro-) psychological assessment. Project 1 of this study is an observational cross-sectional study with four groups that will be conducted at the University Hospital of Psychiatry and Psychotherapy Bern (Switzerland): Patients with at least one suicide attempt in their past (SUAT), patients with suicidal ideation (SUID), patients from the same clinical cohort, without neither suicidal behavior or ideation (CLIN) and the healthy group (HLTH). The cohorts to be examined (SUAT & SUID) will be compared to the two control groups (CLIN & HLTH). Only people who have signed the informed consent and meet the eligibility criteria can participate in this study.
The goal of this pilot RCT is to investigate the acceptability and feasibility of an unguided culturally adapted self-help app for grieving Syrian refugees in Switzerland. Furthermore, the study will examine whether using the app has an effect on secondary outcomes (e.g., grief symptoms).The main questions it aims to answer are: - Is the self-help app culturally acceptable and feasible in this target group and what do we need to adapt? - Does the use of the self-help app reduce grief symptoms? (amongst other secondary outcomes) Participants will be asked to: - Complete a baseline assessment - then use the self-help app for 5 weeks - Complete a second assessment and participate in a short semi-structured interview regarding acceptability and feasibility. Researchers will compare an intervention group to a wait-list control group to see if the use of the self-help app has an effect on secondary outcomes.
