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 purpose of this study is to investigate the impact of supraphysiologic oxygen (hyperoxia) on myocardial function in anaesthetized patients undergoing non-cardiac vascular surgery.
Reverse total shoulder arthroplasty (RTSA) has become an established treatment for cuff arthropathy, severe osteoarthritis and in certain fracture cases. Due to the increasingly aging population, patients who have already exceeded their life-expectancy pose a significant challenge to the shoulder surgeon. Therefore, we wanted to investigate patient demographics, hospital stay length, complication rate functional outcome, patient reported outcome scores and mortality retrospectively for patients, who were older than 83 years at time of implantation of a RTSA.
This is an open-label, randomized, window-of-opportunity phase 2 clinical study evaluating the biological activity of preoperative Stereotactic Body RadioTherapy (SBRT) alone (Arm 1), and combined with subcutaneous (SC) followed by intra-tumoral (IT) administrations of CMP-001 (Arm 2), in subjects with early stage TNBC. Safety and efficacy of the treatments are also examined. The main hypothesis that the study treatment induces an increase in stromal tumor infiltrating lymphocytes (sTILs) will be explored in each arm separately. The study is designed as a randomized selection study, with randomization used to address patient selection bias while each arm is run as an independent study. No formal statistical comparison between the two arms is planned. 40 patients will be equally (1:1) randomized in this study (20 per arm).
Acute compartment syndrome (ACS) after revascularization for acute limb ischemia is a potentially limb-threatening condition and requires urgent fasciotomy. Compression ultrasound (CU) is an established method for measuring intravenous pressure in superficial veins and, for example, can determine central venous pressure in critically ill patients. In cadaver studies, compression ultrasound has been proven to correlate with invasive intra compartmental pressure (ICP) measurements. This study aims to determine CU's added diagnostic value compared to ICP in detecting ACS after revascularisation.
The aim of this pilot study is to provide an assessment of safety and feasibility of early minimally invasive image guided endoscopic hematoma evacuation (within 24 hours of symptom onset) in patients suffering from intracerebral haemorrhage (ICH).
This study is to set up a flexible trial platform using two existing national cohorts of immunocompromised patients (i.e. Swiss HIV Cohort Study [SHCS] and Swiss Transplant Cohort Study [STCS]) to assess the comparative effectiveness and safety of approved SARS-CoV-2 vaccines in immunocompromised patients. This platform will be tested in the frame of an exploratory pilot trial and a framework will be set up to conduct a larger, flexible, randomized controlled trial (RCT) to test approved SARS-CoV-2 vaccines to prevent SARS-CoV-2 infections. The first sub-protocol for a pilot trial is to investigate the operability of a platform trial that is nested into two existing cohort studies and compare immune response, safety and clinical efficacy of the first two mRNA vaccines (Comirnaty® by Pfizer / BioNTech and COVID-19 mRNA Vaccine Moderna®, by Moderna) in immune compromised patients in the Swiss HIV and Swiss Transplant Cohort studies. The second sub-protocol (observational study) is to collect a blood sample before the third vaccination and 8 weeks after vaccination to analyze an additional benefit of a third SARS-CoV-2 vaccine in these immunocompromised patients. In the third sub-protocol (substudy-3; observational) we will recruit patients who have received m-RNA-1273.214 by Moderna in the frame of clinical routine. We will start a second arm of our observational study as soon as another bivalent mRNA vaccine (from Pfizer-BioNTech) has been approved by Swissmedic. We aim to compare the immunologic response and safety of the bivalent mRNA-1273.214 vaccine from Moderna among immunocompromised persons (persons living with HIV or kidney or lung transplant recipients) to the immunologic response of immunocompromised persons who received the bivalent mRNA vaccine from Pfizer-BioNTech.
The aim is to find out more about how corneal sensory fibres react to different types of stimuli (liquid / tactile / nylon thread) and how this can be consciously perceived by the individual. Is it possible to generate a stimulus that delivers a repeatable and reliable response within a useful stimulus force range which allows an interpretation / evaluation of normal / expected activity of superficial nerve fibres in the cornea? The study group will be divided into three groups of individuals: two groups with different types of contact lenses (CL) and one without CL, as sensitivity changes are thought to occur with CL wear. A very interesting research question is to find out, if such sensitivity differences can be detected with the nature of the stimuli applied in this study.
To improve the quality of medical care in the group of poststroke patients, we are planning to examine neurological patients in a rehabilitation clinic simultaneously with a non-contact method (Sleepiz One) and a standard diagnostic polygraphy measurement. This easy and comfortable pre-screening (Sleepiz One) should reduce the barrier for ward physicians to request a sleep study. The method could help to overcome the bottleneck of resource-intense procedures. It is simple to carry out and does not disturb the sleep of the patients. The scoring is done according to the AASM Manual Version 2.6. Patients with a confirmed diagnosis will be informed about therapy options by a sleep physician and receive a recommendation for further therapy in the discharge letter from the rehabilitation clinic. The goal of the study is then to evaluate if a non-contact method, the Sleepiz One, presents an opportunity for a fast and easy pre-screening during rehabilitation. Therefore, the precision of binary classification of subjects based on their sleep apnea severity (AHI >= 15) made by Sleepiz One will be compared to PG data manually scored by expert sleep scorers.
This is a single centre prospective observational study to assess the immune response to SARS-CoV-2 vaccines in cancer patients receiving active treatment or in follow-up at the IOSI and in non-cancer patients (age and gender matched).
The Epios early feasibility study aims to explore the uses of novel sub-scalp lead devices in the detection of epileptic seizures. Epios leads are inserted subcutaneously through dedicated tunneling toolkits and have been designed for continuous EEG recording in inpatients. This clinical investigation is part of a stepwise program to validate the entire Epios system and it starts with the validation of the Epios leads alone in this two steps study.
