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.
In this research project, the investigators want to find out whether the additional intake of vitamin D further reduces the inflammatory events in the intestines of IBD patients. There are three groups of subjects: the 1st group takes a capsule of 24,000 IU per week, the 2nd group takes 24,000 IU per month, the 3rd group is the control group. The intake extends over 6 months during the autumn and winter period.
Development and feasibility test of an Ecological Momentary Intervention (EMI) - Imager, to promote and improve stress resilience, specifically to increase reward sensitivity.
• This study investigates and compares the within and in-between variances of the body responses to different heat stressors in a controlled lab-setting. The participants will be exposed to different heat sources while a variety of physiological heat strain reactions such as heartrate, sweat rate, and core body temperature are recorded using on- and in-body devices. For the participant monitoring during the study, medical grade devices such as a certified ECG and a swallowable sensor-pill to continuously monitor the core body temperature will be applied. A one-for-all wearable device is additionally applied for physiological validation. Further, sweat will be collected to assess (i) the local sweat rate and (ii) the appearance of different heat stress associated molecular markers in this non-invasively collectable biofluid. As a secondary aim, a model will be developed that will enable to predict the different heat stress sources out of the heat strain measurements.
The goal of this observational study is to assess the risk of viral infections in patients receiving hematopoietic stem cell transplantation (HSCT) from a haploidentical donor compared to those who receive HSCT from a HLA-matched donor. The main question it aims to answer is: to describe which viruses are replicating in the blood of the above two patient groups on the day of transplantation and at 1, 3 and 6 months after transplantation. Blood samples taken as part of routine care on the day of transplantation and at 1, 3 and 6 months post-transplantation visits are analyzed and the types and amount of viruses detected in the two groups of patients are described.
This pilot study is to investigate a patient transfer path from the hospital to Hospital@Home to their general practitioners (GPs) using telemedical procedures. Telemedical support will be executed by Medgate who will refer the patients to their GPs after the telemedical consultations are completed. Inclusion criteria is the need for short time follow up procedures that can be handled by telemedicine. Throughout the study, patient and stakeholder satisfaction will be measured and data-based methods will be developed to assess patient transfer success. Overall, new information flow and communication between the stakeholders (hospital, telemedicine and general practitioners) are defined and tested. The Hospital@Home pilot study is intended to become a flagship project for new healthcare models.
The study investigates the effects of a digital, scalable self-efficacy training of repeated recall of self-efficacy memories on mental health outcomes, such as self-efficacy, anxiety, stress, hopelessness, and other mental health outcomes. A total of 94 students with elevated stress levels (≤ 13 on the Perceived Stress Scale) will be recruited and randomly assigned to training and control group. Individuals will either engage in the self-efficacy training app combined with Ecological Momentary Assessment (EMA) for 1 week (training group) or in EMA only for 1 week (control group). Baseline and post assessments will measure changes in self-efficacy, anxiety, stress, hopelessness, and other mental health outcomes.
This retrospective study examines the surgical and antibiotic treatment of diabetic foot syndrome infections treated at the University Hospital Basel since 2019. It analyses the implementation of the hospital in-house guidelines published in 2019 with regard to antibiotic therapy in diabetic foot infections, taking into account clinical, microbiological and histopathological criteria. The defined endpoints are (i) fully compliant with internal policies, (ii) partially compliant with internal policies, and (iii) not compliant with internal policies. The recording of these proportions is descriptive.
Delayed wound healing is considered a health problem with devastating consequences for patients, healthcare systems, and societies. Over the past 20 years, many other groups, as well as ourselves, have evaluated various alternatives to improve wound healing. Despite this, the scientific evidence demonstrating the efficacy of recently developed treatments is often limited. Stratacel® and Stratamed® are two gels approved by Swissmedic and the FDA for use in improving wound healing. To this end, the efficacy of these formulations has been visually tested by a physician or by patients. Using the most advanced medical technologies (confocal microscopy and LCOCT), this study aims to investigate the effect of these formulations on the healing of human skin. For this research, a total of 20 volunteers will be included in this study. Volunteers will have up to 7 follow-up appointments over 21 days. Each appointment will last approximately 30 minutes and will be used to perform external measurements of skin healing. All volunteers will use the same formulations (Stratacel® and Stratamed®) with the only difference between volunteers being the anatomical area of application of the formulation. This will be determined by chance. The active participation of the participant is requested for the application of the formulations on the skin twice a day during the trial.
The aim of this study is to assess the sensitivity, specificity, and accuracy of the Resistell Phenotech device in testing antibiotic susceptibility of Gram-negative bacteria (i.e., E. coli or K. pneumoniae) to clinically relevant antibiotics. The study is designed as a prospective, non-interventional, multi-center, single-arm study. The blood culture samples from bacteremia patients that are positive for E. coli or K. pneumoniae will be tested with the Resistell Phenotech device after strain identification by MALDI-TOF. The results of the Resistell AST will be compared with the results from the disk diffusion tests (all sites use the Kirby-Bauer disk diffusion test), and site dependent tests (VITEK® 2, BD Phoenix™, MicroScan WalkAway system, and/or EUCAST RAST), which are currently the standard AST methods in the microbiology laboratories at the participating sites.
Supervised exercise training (SET) is considered among first-line therapies for patients with symptomatic lower extremity peripheral artery disease (PAD), combined with general cardiovascular risk management, lifestyle adaptation and pharmacological treatment. Although without clear consistency, the guidelines give recommendations in terms of claudication pain severity, SET volume, duration, and frequency. However, no or little guidance is offered as far as training intensity is concerned. Most of the previous studies on SET, in the context of PAD, did not distinguish between symptom intensity and common training intensity measures such as % of maximal heart rate (%HRmax), % of HR reserve (%HRR), % of peak oxygen uptake (%VO2peak), % of VO2 reserve (%VO2R), or the rate of perceived exertion (RPE). In a recent meta-analysis, we demonstrated that both training modality and exercise intensity (based on %peak heart rate, %peak oxygen uptake, or the rate of perceived exertion) should be considered when looking for the best results in patients with symptomatic PAD. These results call for study of the individual roles of each exercise intensity and modality on walking performance and cardiorespiratory fitness in patients with symptomatic PAD. High-intensity interval training (HIIT) is composed of brief bursts of vigorous intensity interspersed with periods of rest or low-intensity exercise. HIIT may be better than moderate-intensity training (MIT) in improving cardiorespiratory fitness and functional capacity in patients with cardiovascular and metabolic diseases, but in patients with symptomatic PAD, the effects of such modalities on walking ability and cardiorespiratory fitness remain to be clearly determined. The primary objective of this study is to compare the effects of 12-week-long exercise training (short-duration high-intensity intervals vs. low-to-moderate intensity) on treadmill performance in patients with symptomatic PAD. It is hypothesized that treadmill performance would be improved to a greater extent after high-intensity exercise training
