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.
CYP2D6 metabolizes ~25% of all marketed drugs. There is an important variability in the activity of this enzyme among individuals. The cause of this variability might be environmental, genetic, ethnical or even related to a disease. The administration of a CYP2D6 probe drug (e.g. dextromethorphan) is a good way to characterize CYP2D6 phenotype. Nonetheless, it is relatively invasive and the vulnerable population (e.g. pregnant women) cannot be phenotyped in this manner. Therefore, finding an endogenous substance which is metabolized by CYP2D6 could replace usual phenotyping procedure using a probe drug. This study evaluates the impact of a CYP2D6 inhibitor and of genetic polymorphism on the metabolome of healthy volunteers in order to identify new CYP2D6 biomarkers. To this end, untargeted metabolomics analysis using LC-HRMS will be performed on plasma and urine samples This single-centre open-label clinical trial will include 40 healthy subjects (men and women) between 18 and 65 years. Eligible participants will be assigned to a study group according to their CYP2D6 genotypes: poor metabolizers (PMs) and extensive/ultrarapid metabolizers (EMs-UMs). Two sessions will take place for each subjects. Session 1: CYP2D6 phenotyping (dextromethorphan 5 mg, single dose) Session 2: idem session 1 with prior uptake of a CYP2D6 inhibitor (paroxetine 10 or 20 mg, one dose a day for 7 days). In both sessions, urine will be collected up to 24 hours and capillary/venous blood will be sampled before phenotyping for metabolomics analyses. Urine will also be collected for 4 hours after dextromethorphan intake in order to phenotype the CYP2D6 enzyme.
In a non-anatomical resection of a liver tumor, only the part of the liver with the tumor and a safety margin of 5 - 10 mm are resected. This is done to ensure a negative resection margin, which means that no tumor cells are at the boundary of the resection. These non-anatomical resections can be performed repeatedly in case of recurrence. However, compared to anatomical resections, it is more challenging to keep a negative resection margin as anatomical landmarks cannot be used for intra-operative guidance. In this study, the investigators aim to clinically evaluate a 3d navigation system, where navigated intra-operative ultrasound data is used to create a virtual model and a surgical plan.
Phonak Hearing Devices pass through different development and study phases. At an early stage, feasibility studies are conducted to investigate new algorithms, features and functions in an isolated manner. If the benefit is proven, their performance is then investigated regarding interdependency between all available algorithms, features and functions running in parallel in a hearing aid (pivotal/pre-validation studies) and, resulting from the pre-validation studies, they get optimized. Prior to product launch, the Phonak Hearing Systems get reviewed by a final quality control in terms of clinical trials. This is a validation study, investigating improved algorithms, features, functions and wearing comfort. This will be a clinical investigation which will be conducted mono centric at Sonova AG Headquarters based in Stäfa (Switzerland).

This qualitative study with quantitative elements examines the health care provided to women who suffered from mental disorder during pregnancy and / or in the first year after birth (i.e. during the perinatal phase). Investigators will perform individual interviews with former PMD patients, and health and social care professionals to gain insights into current health care for PMD patients.
The registry aims to follow clinically all consecutive patients treated by percutaneous coronary interventions at hospital & university Fribourg.
This study will compare the efficiency of the iPad distraction or the administration of Nitrous Oxide on the anxiety decrease when a peripheral venous catheter is needed in children between 3 and 9 years old.
This intervention study aims to evaluate the effectivity of web-based cognitive therapy in reducing depression and anxiety in pregnant and postpartum women. Moreover, it aims to assess treatment feasibility and usability of the treatment in the same population. After an initial screening to determine the eligibility to participate, all participants fulfilling the inclusion criteria will receive their personal access login in order to start the intervention.
Background and Rationale: The gold standard to assess fever, is to conduct invasive intravascular, esophageal or bladder thermistor core body temperature (CBT) measurements. Since these methods are time consuming for the medical staff and more importantly displeasing to the patients, alternative CBT/fever assessments is needed. greenTEG is developing a CBT algorithm that will be able to reliably calculate CBT continuously form skin temperature (ST) and the corresponding heat flux (HF). This can be achieved from subjects developing fever in intensive care unit, since the prevalence of fever is high and optimally assessed. Objective(s): The aim of this study is to develop and validation of an algorithm that allows the detection of fever in patients through a non-invasive wearable prototype sensor, which calculates CBT from ST, HF and heart rate (HR) data streams, allowing a more effective patient management Endpoint(s): ST, HF, HR and CBT data are collected for at least 24hrs until 3 day, depending on the ICU length of stay of the patient. ST, HF, HR and CBT values from different measurement positions (subclavicular, lateral ribcage, upper arm and wrist) of the non-invasive wearable research prototypes will be compared with each other and compared to clinical invasive method particularly CBT measured by blood temperature from a pulmonary catheter if present or vesical temperature Study Design: Interventional-Single Group Assignment, monocentric, open label. Statistical Considerations: The measure of quality will be the mean absolute difference (MAD) between the CBT prediction and the reference signal where the mean is taken over the whole measurement of a single candidate. An aggregate performance measure over a group of candidates is defined by averaging the MAD values of each candidate in the group. When a group of candidates for algorithm validation is defined, the total improvement will be defined by comparing aggregate performances of old and new algorithm for the validation group. Balancing the probability of occurrence of the factors in the population and the overall size of the study, a final size of 50 candidates is reasonable. Inclusion- / Exclusion Criteria: Inclusion criteria: - Age ≥18 years old. - Patients which are treated at the cardiosurgical and vascular intensive care unit of the University Hospital Zurich. - Expected length of stay in the intensive care unit at least 24 hours - Clinical standard monitoring including an invasive CBT measurement (e.g. blood temperature from a pulmonary catheter if present or from a vesical catheter routinely placed) - Informed consent signed by the patient Exclusion criteria: - Acute medical contraindications against the measurement of the non-invasive wearable device (e.g. skin diseases) and band-aid allergies. - Implanted pacemakers or other implanted life sustaining devices - Comatose state of the patient - Pregnant Women Number of Participants with Rationale: Number of participants in the study :50 candidates. The study will be divided in two parts. In the first part data are collected from 38 patients. In the second part, data form 12 patients will be collected. The reason for the first part is to collect data in order to develop the algorithm. The reason to collect additional data from 12 candidates in the second part is to validate and adjust the algorithm that is develop in the first part of the study. Study Intervention: 50% of the research prototypes (4 pieces) will be mounted to the patient on left side of the body (sub clavicula, lateral ribcage, upper arm and wrist), after being admitted to the ICU and having signed the informed consent. As soon as a patient gets fever, the other 50% of the research prototypes (4 pieces) will be applied on the right side of the body (sub clavicula, lateral ribcage, upper arm and wrist). Control Intervention: Not applicable Study procedures: Patients will be recruited and screened 1-3 days before the measurements starts. 50% of the research prototypes (4 pieces) will be applied to the patient on the left side of the body (sub clavicula, lateral ribcage, upper arm and wrist), after being admitted to the ICU and having signed the informed consent. After the development of the fever, the other 50% of the research prototypes (4 pieces) will be applied on the right side of the body (sub clavicula, lateral ribcage, upper arm and wrist). At the end of intervention all prototypes will be removed from the patient. A greenTEG employee will collect all the prototypes.
