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.
With the proposed study, the investigators aim to evaluate the long-term efficacy of the open-label placebo (OLP) intervention in premenstrual syndrome (PMS) and to contribute to a broader understanding of how OLPs work. It is planned to survey participants of the intervention groups (OLP+ and OLP-) regarding symptom intensity and impairment due to PMS after the conclusion of our randomized controlled trial (RCT) and intervention provision. Additionally, it will be examined if there is a difference between the OLP group with and without a treatment rationale (OPL+ vs. OLP-) across time. More precisely, it will be investigated whether participants of the intervention groups with and without treatment rationale experience any long-term improvement.
A prospective patients' registry collecting all new cases of AL amyloidosis evaluated at referral Centers from across Europe and a sample sharing network will be created to study mechanisms of the disease through the use of advanced molecular technologies and big data analysis tools.
The goal of this observational study is to learn about the relation between grip position and maximal strength and power in wheelchair rugby and basketball athletes. The main question is to investigate the relationship between maximal isometric force, acceleration, and sprint time. Participants will - pull in their sport wheelchair against a force transducer - push in their sport wheelchair from a force transducer - accelerate as fast as possible with one push - accelerate as fast as possible over a distance of 20m Researchers will compare the wheelchair basketball against wheelchair rugby players to see if there is a difference in the parameters.
Transient mild hypothermia (core body temperature 35-32°C) is common and usually without consequences for the brain or other organs. However, prolonged severe accidental hypothermia (core body temperature below 28°C) due to accidents is rare, and usually fatal in more than 50% of cases. Little is known on its physiopathology, on prognostic factors for rewarming decision or ideal rewarming techniques for better survival. Furthermore, complications after successful rewarming are extremely frequent and very often severe or fatal. Accidental hypothermia is a frequent problem during the winter months and can be caused by snow sport accidents, near drowning and urban cold exposure. The International Hypothermia Registry's principle goal is to increase knowledge on accidental hypothermia by creating the largest database on accidental hypothermia which will comprise enough patient data to give a statistical power since the causes of accidental hypothermia and its treatment varies greatly. The International Hypothermia Registry (IHR) will enable improvement of pre- and in-hospital treatment and rewarming methods, study survival predictors and prevention of post-rewarming complications. By this way, the IHR will permit the establishment of evidence-based diagnosis and treatment guidelines.
Given the high prevalence of mental health issues, such as anxiety and depression, in pretrial detainees, the Swiss Federal Justice Department (SFJD) approved a model trial ("Modellversuch Untersuchungshaft", MV). The MV will be carried out in 11 pretrial detention facilities in the cantons of Zurich and Bern and aims to improve the wellbeing and social integration of individuals in pretrial detention. As part of the MV the investigators are evaluating the impact of two interventions using a randomized controlled trial (RCT). The first intervention, "Prison Stress Management" (PRISMA), addresses the issue of poor mental health of inmates during pretrial detention and after release. PRISMA is a scalable World Health Organization (WHO)-developed psychological intervention based on cognitive-behavioral therapy (CBT) program and goes beyond the status-quo mental health support offered in jails. Currently, only inmates with severe mental health problems are referred to the psychiatric ward of the health services provided in jails and no continuation of support is offered after the transition to the outside world. The second intervention (SOCIAL) uses extended social services to address potential disruptions incarceration might cause in detainees' social and economic lives. The isolation from the outside world implies that detainees might lose their jobs and housing, their relationships with their family and friends are strained, all factor hindering re-integration into society and taxing their mental wellbeing. This project will provide much needed insights to criminal justice authorities to design detention facilities and the detention experience in ways that empower incarcerated individuals to cope with the disruptions and psychological stress that come along with their detention.
This is a randomized, double-blind sham-controlled monocentric trial. 30 patients that are diagnosed with hypertension and with moderate to severe chronic kidney disease are included in this trial. 20 of them are randomized into the active treatment arm, 10 into the sham arm. Low-intensity extracorporal shock wave (Li-ESWT) sessions (arm1) or sham sessions (arm2), will be administered with a dedicated probe within three consecutive weeks to the kidneys of patients.The study will add data to the effects of the shock wave treatment on blood pressure and will assess whether this treatment improves renal function, perfusion and oxygenation. The study includes a third arm (arm3) in which treatment sessions are administered to patients that were in the placebo group in the first phase of the study (arm2).
The goal of this randomized crossover trial is to compare the results of a stationary and a mobile ergospirometry system in 20 healthy endurance trained participants. The main question it aims to answer is to investigate the differences in VO2-measurements between the mobile K5 and the stationary Quark ergospirometry system. Participants will do a maximal ramp test followed by a sub maximal step test with 6 stages on two different days.
Objective: This study is designed to address the complex interplay between the gut microbiome, environmental factors, and inflammatory diseases, with a specific emphasis on serving as a healthy cohort for several related projects. Primary hypotheses: Since data from this study will be used as control data for four studies, four primary hypothesis will be defined. Hypothesis H1: Levels of intestinal inflammation will be substantially higher in Zimbabweans living in rural areas and low-resource settings (i.e. high-density areas) compared to Zimbabwean and Swiss individuals living in high-resource settings. Hypothesis H2: Bottlenecks and blooms of bacterial strains are less frequent in healthy participants than in inflammatory bowel disease (IBD) patients and bacterial strains will have lower mutation rates in healthy patients when compared to strains from IBD subjects (partner study: BASEC 2021-00871). Hypothesis H3: Longitudinal changes of the faecal microbiome of healthy Swiss individuals differ systematically compared to longitudinal changes of the faecal microbiome of Swiss UC patients with active disease (partner study: BASEC 2022-02008). Hypothesis H4: The HRV of healthy Swiss individuals differ systematically from HRV of Swiss IBD patients and can be associated with differentially abundant bacterial taxa (partner study: BASEC 2022-02008).
This clinical trial at the University Department of Geriatric Medicine FELIX Platter in Basel, Switzerland, is designed to evaluate a new transitional care model aimed at helping frail older adults after they get discharged from the hospital. The AdvantAGE study aims to explore the following questions: - Does the new care model help reduce the number of patients who need to return to the hospital within 90 days? - How effective is the implementation of this care model? Participants in the trial will be followed by advanced practice nurses for up to 90 days after hospital discharge. The patients and their caregivers will receive support in coordinating care, managing medications, and learning to manage the patient's health conditions on their own. Additionally, they will have the opportunity to engage in discussions about advanced care planning.
The goal of this international, multicenter, mixed retrospective-prospective, exploratory, observational study is to establish an international registry to fill the knowledge gap created by the rarity of lenticulostriate and basilar perforator aneurysms and the resulting lack of knowledge about their natural history, diagnostic evaluation, management, and clinical outcomes. Specifically, comparative analyses of outcomes in patients with intracranial perforator aneurysms treated conservatively, endovascularly, and surgically will be performed. The study will also evaluate the size and location of lenticulostriate and basilar intracranial perforator aneurysms, collect information on the specific type of endovascular treatment used, compare patients with predominantly perimesencephalic subarachnoid hemorrhage (SAH) who have a perforator aneurysm to those without, and evaluate spontaneous occlusion in conservatively treated aneurysms. Core lab analysis of these aneurysms on various imaging modalities will be performed at the Inselspital and changes in aneurysm characteristics over time will be documented. In addition, the relationship between baseline characteristics and aneurysm characteristics on the incidence of hemorrhage will be examined. The study will involve approximately 20-30 centers worldwide with an estimated total sample size of 200-300 patients by 2025.
