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.
This prospective study is to explore different predictive factors for response to steroid treatment in patients with PMR and/or GCA. It evaluates the association of endogenous GC suppression (plasma and urinary cortisol and cortisone) to the responsiveness of PMR/GCA to GCs.
By bringing together the fields of seizure detection and that of Sudden Unexpected Death in Epilepsy (SUDEP), the current project aims at delineating which set of biosensors and related biomarkers would optimally characterize the severity of GTCS and the associated risk of SUDEP.
The VOYAGER study is a primary data collection, non-interventional, prospective, multinational, multicenter study. It is designed to collect real-world, long-term data to explore long-term effectiveness, safety, clinical insights, treatment patterns, and factors driving the treatment decisions among patients being treated with specified Roche ophthalmology products (Faricimab and Port Delivery System with Ranibizumab) in approved retinal indications (neovascular age-related macular degeneration [nAMD] and diabetic macular edema [DME]) in routine clinical practice. This study will not provide or make recommendations on use of any products including Roche products; treatment decisions will be determined by the treating physician and must be made independently to the decision to participate in this study. Participation in this study will not change or influence a patient's standard of care in any way.
The investigators will collect PAP-test samples from women undergoing colposcopy. Laboratory providers will prepare the samples with a liquid-based cytology method. The providers will then digitalise the slides using a digital scanner. The slides will be sent to cytopathologists who will assess the quality of the slides.
In this preliminary short-term study it is investigated, whether a short olfactory stimulation with distinct odours impacts energy expenditure in patients with obesity and lean patients.
Investigation of underlying metabolic mechanisms and impact on the two surgical procedures on inflammatory factors.
This is an open-label, non-randomized trial that will be conducted at three clinical sites, Thomas Jefferson University (TJU), the Hospital of the University of Pennsylvania (HUP) and University of Bern (UB). Enrollment will be allocated into one of 4 different cohorts depending on the inclusion criteria for each cohort. Cohort 1: Patients scheduled for hepatic vein pressure gradient (HVPG) measurements will subsequently undergo two consecutive SHAPE (subharmonic aided pressure estimation) procedures using different ultrasound contrast agents (Definity [Lantheus Medical Imaging, N Bilerica, MA, USA] and Sonazoid [GE Healthcare, Oslo, Norway] in randomized order) to estimate portal pressures with a Logiq E10 scanner (GE Healthcare, Waukesha, WI, USA) and determine the reproducibility of the SHAPE algorithm. Cohort 2: Patients identified as having clinically significant portal hypertension (CSPH) will be monitored by SHAPE with Sonazoid for the duration of this project (18-24 months on average). These subjects will have follow-up ultrasound scans every 6 ± 2 months to check for hepatocellular carcinoma (HCC) (using the Barcelona-Liver Cancer staging system) as well as ascites and at those times a repeat SHAPE examination will be performed. Liver stiffness values will be measured with elastography as well. This cohort will examine if serial SHAPE can accurately predict development of ascites and other liver related events in patients with compensated cirrhosis undergoing routine HCC surveillance in a multi-center setting. Cohort 3: Subjects newly diagnosed with portal hypertension and starting treatment with non-selective β-blockers will be monitored with SHAPE and results compared to elastography measurements of liver stiffness with standard assessments (e.g., serum liver function tests and measurement of spleen size as well as platelet count). This cohort will establish if SHAPE can be used to monitor treatment response in patients identified with portal hypertension. Cohort 4: Patients with compensated advanced chronic liver disease scheduled for an endoscopy examination for screening of varices relative to the Baveno VI and the expanded-Baveno VI criteria as well as the AST to Platelet Ratio Index will undergo a SHAPE examination. This cohort will compare the predictive ability of SHAPE for allocating patients with compensated advanced chronic liver disease to screening of varices compared to the current standard of care.
Acute respiratory infections are a common reason of attendance at emergency departments. It is also the main reason of unnecessary antibiotic prescription. Antibiotics save lives, but can also directly harm patients by causing antibiotic-associated adverse events. Antibiotic use is directly related to resistance, which is one of the major threats of our century. In addition, some microorganisms live in and on the human body and promote many aspects of our health. Antibiotic treatment can disturb those microorganisms and therefore have long-lasting negative effects on our health. Unfortunately, it is difficult to differentiate between viral infections, which usually heal spontaneously, and bacterial pneumonia, which needs antibiotics treatment. This is one of the reasons of this over-prescribing of antibiotics. This project aims to reduce widespread use of antibiotics in the emergency department through a new diagnostic strategy of bacterial pneumonia. This strategy includes sequential use of well-known techniques: a clinical score, lung ultrasound and finally a biomarker, procalcitonin. The latter tends to be higher in bacterial infections. The combination of these different tests improves the diagnostic process and allows improved use of targeted antibiotics, with the ultimate goal of better patient management. The study will compare the antibiotic prescription rate and the clinical course of patients managed using this new diagnostic approach with those managed as usual. The project will also evaluate the acceptability and feasibility of this strategy and its cost-effectiveness. These two aspects are essential for a wider implementation of this innovative diagnostic approach and decrease antibiotic resistance.
This is a Post-Marketing Surveillance of GMK SpheriKA knee stem prosthesis.
This is a Phase Ib/II, open-label, multicenter, randomized, umbrella study in participants with locally advanced squamous cell carcinoma of the head and neck (SCCHN). The study will enroll treatment-naive participants with resectable Stage III-IVA human papillomavirus (HPV)-negative, programmed death-ligand 1 (PD-L1)-positive SCCHN with measurable disease, as assessed by the investigator according to Response Evaluation Criteria in Solid Tumors, Version 1.1 (RECIST v1.1) who have not received systemic treatment for their disease.
