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.
The hypothesis of MAP IN HEART is that catheter ablation for post-infarction ventricular tachycardia (VT) can be largely improved through a direct definition of primary ablation targets from pre-operative CT scan imaging. The objective of is to demonstrate that catheter ablation of post-infarction VT targeting left ventricular wall thickness channels as defined from CT scan is feasible and associated with favorable efficacy, efficiency and safety profiles. A single-arm prospective cohort study will be conducted, including 40 patients over 3 European centres. Baseline, procedural and 6-month follow-up data will be analyzed
The study design is a single-center prospective pilot study. Hypothesis: Results of cerebral fNIRS examination in unconscious patients with severe hemorrhagic or ischemic stroke in the ICU are congruent with the results of SSEP and AEP. Hence, making it a potential prognostic tool for unconscious ICU patients. In a specific subgroup of unconscious patients after cardiac arrest and cardiopulmonary resuscitation the fNIRS measurement is congruent with the results of electroencephalography (EEG). The primary purpose of this study is to evaluate the agreement of the results of fNIRS examination to those of evoked potentials and EEG in unconscious ICU patients with severe hemorrhagic, or ischemic strokes or hypoxic brain injury after cardiac arrest and cardiopulmonary resuscitation. fNIRS will be compared to evoked potentials in an experimental group consisting of unconscious neuro-intensive care patients and in a control group consisting of healthy, conscious subjects. To compare fNIRS with evoked potentials there are two test phases: 1. The cerebral response to a somatosensory stimulus (peripheral nerve stimulation) is measured by fNIRS and SSEP 2. The cerebral response to an auditory stimulus is measured by fNIRS and AEP To avoid biases the following has to be considered: - The timing of the measurements plays an important role. A time difference between compared measurements can influence the outcome significantly due to deterioration or recovery of the neuronal network during the time gap. Therefore, fNIRS and evoked potentials will be measured simultaneously. - If the compared measurement methods are conducted by the same researcher the possibility of bias is high. Hence, two different researcher will conduct each one measurement without knowing the results of each other during the measurement.
Multiple Sclerosis (MS) is a chronic inflammatory disease leading to the demyelination of the central nervous system. Promoting physical activity has gathered attention as an effective means to improve health-related quality of life and to mitigate symptoms such as fatigue and depressive symptoms in individuals suffering from MS. However, persons suffering from MS often experience difficulties in staying active. A comprehensive understanding of barriers to staying physical active for persons with MS in Switzerland is currently lacking. Given the importance of physical activity in the context of MS a detailed understanding of this matter would be key for future research and treatment. A key challenge when studying physical activity in the context of MS is to obtain objective and accurate measurements that are not prone to reporting bias. While accelerometer-based measurements hold promise in this regard they are not convenient for routine implementation in real-world environments. Initial research has identified consumer-grade wearables such as Fitbits as a promising alternative whereby focusing on the main outcome average step count. Given the rich detail of activity patterns that can be derived from such devices, research has so far underutilized the available information that has the potential to provide more comprehensive insight into this matter. Objectives: The present project aims to determine the common factors in real-life settings limiting physical activity in persons with MS and the impact of these barriers on physical activity. Further, the present study aims to provide precedence for future research investigating physical activity in MS by examining the quality, reliability, internal consistency, and validity of PA metrics derived from the wide-spread consumer-grade activity tracker Fitbit in comparison to an accelerometer.
Uncomplicated costal fractures often result in persistent pain over the long term. Indeed, cohort studies showed that at 6 months, 22% of patients still had pain and 56% had functional disability. The impact of costal fractures on quality of life is underestimated. The socio-psycho-economic consequences are substantial. Previous studies have shown that an important factor for persistent pain and functional disability is the intensity of the initial pain. However, preliminary studies have shown promising results with surgical fixation of rib fractures: reduced need for analgesic drugs, reduced pain at 1 month, reduced complications and improved motor skills in patients over 65 years of age. To date, the only clinical trials that exist focused on the fixation of complicated rib dislocations. While fixation of uncomplicated rib fractures is a common practice, no randomized studies have been conducted to evaluate its impact on pain and quality of life in the medium and long term. In this context, the aim of our randomized study is to compare pain at 2 months between operated and non-operated patients with uncomplicated rib fractures.
ID/IDA affects many young children in Africa. Vaccines provide tremendous benefits in LMIC; however, they currently fail to reach their full potential. We need to better understand the causes of vaccine failure, in order to develop new strategies to improve vaccine immunogenicity. This study will contribute to children's health by: (1) providing updated guidelines to better define the prevalence of ID/IDA in early infancy, and its safe and effective control using iron; and (2) providing a new approach to improve response to pediatric vaccines in LMIC, by ensuring adequate iron status at time of vaccination.
In our society the population consists of more elderly patients. Medical treatment needs to be adjusted to this patient group. This research project focusses on patients with a fragility fracture of the pelvis. This results from a minor trauma and can cause a long immobilization period because of severe pain. For FFP type II b and II c there is no consensus on the best treatment option. Either a surgical minimal invasive sacroiliac osteosynthesis or conservative treatment is a possibility. Of course, both treatment options have pros and cons. This research project will randomize all patients with a FFP IIb or IIc fracture in either surgical or conservative treatment. These treatments will be evaluated at the follow-ups, 4 weeks, 4 months and 1 year after trauma. This will be evaluated with the DEMMI, Accelerometer, EQ-5D (EuroQol Quality of Live Questionnaire), radiological results, range of motion, pain-levels and reporting any postoperative complications or adverse events. Patient will be included over a period of 18 months and will be followed for at least a year. This research project aim to answer the question which treatment option for FFP type IIb and IIc is the most adequate.
This study evaluates the diagnostic performance and safety of [18F]PSMA-1007 PET/CT imaging in patients with suspected recurrence of prostate cancer after previous definitive treatment.
Phase 2 Study Investigating the Efficacy of AMT-101 in Subjects with Chronic Antibiotic-resistant Pouchitis
The purpose of this study is to evaluate the safety and efficacy of fixed dose coformulated pembrolizumab/quavonlimab (MK-1308A) plus lenvatinib in a first line (1L) hepatocellular carcinoma (HCC) setting. No hypothesis testing will be performed.
Reduced Hypoxic Ventilatory Response (HVR) and systemic O2 saturation subsequently leading to blunted aerobic capacity as well as decreased overall physical and cognitive performance are the main physiological challenges faced by prematurely born individuals in hypobaric hypoxia (i.e. during high altitude sojourn). While these phenomena have been described previously, the underlying mechanisms are currently unresolved. Given that the reduction in altitude-performance and its underlying mechanisms are not well understood, it is currently impossible to give evidence-based recommendation for altitude sojourns in this cohort. It is also of note, that even hypobaric hypoxia exposure during long-haul flights might be detrimental to well-being of pre-term born individuals. The present project aims to comprehensively investigate physiological responses to altitude/hypoxia during rest and exercise in prematurely born, but otherwise healthy adults. Specifically, we aim to elucidate the underlying mechanisms of the altered resting and exercise cardiovascular, respiratory, cerebral and hematological responses to hypoxia in prematurely born individuals. The obtained results from this cohort will be compared to the data from a control groups consisting of healthy, age and aerobic capacity-matched individuals born at full-term. While acute hypoxic effects will be the focus of the project's first phase, we will test the effect of prolonged terrestrial (real) or simulated (normobaric hypoxia) altitude exposures in the second part. This phase will, in addition to the insight into the prolonged altitude acclimatization modulation in prematurely born individuals, also enable us to investigate the potential differences between the effects of normobaric (simulated) and hypobaric (terrestrial) hypoxia in this cohort.
