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 ongoing warfare and economic instability in the Middle East and in North Africa causes many people to leave their home countries. Arrived in a host countries, in this example, in Switzerland, they face a lot of structural and psychosocial hurdles. Particularly in the first years, building up a certain quality of life is complicated and challenging. To support this process, the Swiss Red Cross and the University of Bern have developed the Sui app. It contains structural and social information as well as low-intensity psychological tools to provide support to the everyday life of Arabic-speaking people in Switzerland.
The management of patients with unprotected left main coronary artery (LMCA) disease undergoing percutaneous coronary intervention (PCI) in contemporary interventional cardiology practice remains matter of intense debate. Particularly, the combination of the optimal drug-eluting stent (DES) selection and antiplatelet regimen for patients who require LMCA PCI remains undetermined. Newest-generation thin-strut polymer-free drug-coated stents have the potential to further mitigate chronic inflammation and promote faster re-endothelialization. In the LEADERS FREE randomized trial, PCI with the early-generation BioFreedom (Biosensors International, Switzerland) thick-strut stainless-steel drug-coated stent group was associated with significantly lower rates of the primary safety endpoint, defined as a composite of cardiac death, myocardial infarction, or stent thrombosis at 12 months compared to bare-metal stents among 2,466 patients at high-risk of bleeding who received one-month dual antiplatelet therapy (DAPT), a difference driven by a significantly lower risk for clinically driven target-lesion revascularization. In the ONE-MONTH DAPT randomized study, which enrolled 3,020 patients with coronary artery disease considered for PCI for noncomplex lesions, the rates of the primary composite endpoint of cardiac death, nonfatal myocardial infarction, target vessel revascularization, stroke, or major bleeding within 12 months occurred similarly in patients treated with 1-month DAPT after PCI with early-generation thick-strut stainless-steel polymer-free drug-coated stent (BioFreedom, Biosensors International, Switzerland) and those treated with 6- to 12-month DAPT after newer-generation biodegradable polymer DES (Biomatrix, Biosensors International, Switzerland or Ultimaster, Terumo Corp., Japan) implantation. However, no dedicated randomized clinical trial to date has evaluated the safety and efficacy of newest-generation thinner-strut cobalt-chromium polymer-free drug-coated stents combined with a P2Y12 inhibitor-based SAPT strategy among patients undergoing highly complex PCI procedures, such as those treated for LMCA disease. Recent evidence from a large-scale meta-analysis of several randomized clinical trials including >32'000 patients indicated that 1-3 months of DAPT followed by P2Y12 inhibitor single antiplatelet therapy (SAPT) after second-generation DES implantation was associated with lower risk for major bleeding and similar risk for adverse ischemic outcomes compared with conventional DAPT. These findings suggest that P2Y12 inhibitor SAPT following a short DAPT course (1-3 months) may represent a valuable treatment option for patients undergoing PCI with newer-generation DES compared to standard conventional 12 months DAPT, but this strategy has never been investigated in dedicated randomized clinical trials focused on patients at highest-risk for ischaemic events, such as patients undergoing LMCA PCI. The ULTRA-LM randomized trial aims at filling this current gap of knowledge, which may have large impact on clinical practice and international guidelines. ULTRA-LM will be the first randomized clinical trial to investigate the safety and efficacy of a novel thin-strut cobalt-chromium BioFreedom Ultra polymer-free drug-coated stent (Biosensors International, Switzerland) combined with P2Y12 inhibitor-based single antiplatelet therapy among patients undergoing PCI for LMCA disease.
The PRESC1SE-MI study compares two algorithms for triage of patients presenting with chest pain and symptoms of heart attack (myocardial infarction) to the emergency department. Both algorithms are recommended by the European Society of Cardiology: the 0/3-hour algorithm and the 0/1-hour algorithm. Currently, most emergency departments worldwide use the 0/3-hour troponin algorithm. Cardiac troponin (cTn) is a heart-specific biomarker which indicates damage of the heart muscle and which increases after a heart attack. In the 0/3-hour algorithm, the amount of troponin in the bloodstream is measured with a high-sensitivity assay at admission and 3 hours thereafter. Likewise, the 0/1-hour algorithm means that the blood sample in which the troponin is measured is collected at admission and 1 hour later. Since recent clinical studies suggest that the 0/1-hour algorithm is superior to the 0/3-hour algorithm, many hospitals consider switching to the 0/1-hour algorithm. The aim of this study is to assess how feasible the time-saving 0/1-hour algorithm would be in reality and whether it provides the same accuracy and safety in the diagnosis of myocardial infarction as the current practice the 0/3-hour algorithm.
In this study, a patient space occupied by a patient with confirmed COVID-19 in an open-space multiple bed area in the Intermediate Care Unit will be equipped with a mobile, optimally placed high efficiency particulate air ("HEPA")-equivalent air filtration unit ("Baldachin") in addition to existing hospital policy infection prevention and control measures. The investigators are going to evaluate this intervention regarding its capacity to prevent the nosocomial onwards transmission of Sars-COV2 to patients located in the same multiple-bed open space patient area.
The general decolonization of the human body surface by industrial antiseptic agents, before elective surgery is recommended by the World Health Organization (WHO). A specific randomized-controlled trial specifically among high-risk adult orthopedic patients for infection has not been performed. In this single-center, prospective, randomized, and controlled superiority trial, which is planned over a period of two years, we target on an orthopedic patient population with an elevated risk for revision surgery and surgical site infections
This is a prospective, multinational, multicentre, randomised, parallel-group, open-label study to assess the safety, tolerability and performance of the NucleoCapture extracorporeal apheresis device in the reduction of circulating cell-free DNA (cfDNA)/Neutrophil Extracellular Traps (NETs) in sepsis patients.
The purpose of this study is to evaluate the efficacy, safety and tolerability of pelacarsen (TQJ230) administered subcutaneously once monthly compared to placebo in slowing the progression of calcific aortic valve stenosis.
The primary purpose of this study is to characterize the pharmacokinetics and pharmacodynamics of treatment with ravulizumab intravenous infusion in pediatric participants with gMG.
This retrospective study aims at analysing demographics and clinical, functional and biomechanical outcomes in patients after ACL injury (conservative therapy and/or surgery) in patients of different ages and healthy controls. Demographics, as well as clinical, functional and biomechanical parameters were collected between 2019 and 2022 in two research projects approved by the Ethikkommission Nordwestschweiz (EKNZ 2019-00491, EKNZ 2019-01315, EKNZ 2020-00551). The primary research question analyzes if maximal SLH distance and LSISLH distance are related to the predictors age, sex, isokinetic muscle strength and the presence of injury.
The goal of this interventional study is to test the influence of food intake with characteristics of the urinary bladder. The main questions it aims to answer are: - How does food intake modify the characteristics of urothelial cells? - Does change of specific diet regimes influence biomarker characteristics in urine? Participants will follow specific diet regime for a given time period. After completion of this period biomarker assessment is performed. Thereafter the participants follow an opposite diet regime for the same time period with identical biomarker assessment at the end. Biomarkers within the participants and between the diet regimes will be compared to investigate the influence of food intake on the urinary bladder.
