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.
In patients with cirrhosis (scarring of the liver), bacterial fragments leak from the gut into the blood and cause harm. This study looks into a new way to lower the leakage of bacterial fragments into the blood. Yaq-001 is a new type of carbon that in previous laboratory studies has been shown to have the ability to bind these bacterial fragments and so confine them to the gut. The purpose of this clinical trial is to test the product Yaq-001 for the first time in patients with cirrhosis. This trial will assess if the treatment with Yaq-001 is safe, is well tolerated, and if it helps improve the overall health status of the cirrhotic patients. Candidate patients must be at least 18 years old and have a clinical diagnosis of cirrhosis for any cause. Only postmenopausal women or with surgical sterilisation are eligible. Additional inclusion and exclusion criteria of medical nature will be determined with the investigator at the screening visit, by means of standard care routines plus an additional test to assess the bowel transit time. Eligible patients will be randomly grouped to receive standard care treatment plus Yaq-001, or standard treatment plus placebo (non-active treatment). The use of placebo is necessary to better understand how safe and tolerable Yaq-001 really is. The treatment lasts for 12 weeks. During treatment, the patient will be visited by a study doctor 5 times. At all the visits the patients will undergo a routine physical examination, electrocardiogram, collection of blood and urine samples. On three occasions the patients will be asked to provide additional samples of blood, urine and stool for analysis outside the hospital. 56 patients from 9 hospitals in UK, France, Italy, Portugal, Spain and Switzerland will participate in this study.
The aim of this quality control study is to describe the presence and intensity of postoperative nausea and vomiting (PONV) and its correlation with intraoperative fentanyl dosing. Additionally, the investigators will examine pain scores.
The purpose of the study is to investigate whether hypoglycaemia observed after food intake in bariatric patients can be either influenced by an SGLT2 inhibitor, empagliflozin, or via inhibition of inflammation with an human interleukin-1 receptor antagonist (IL1-RA, anakinra).
Treatment of malignant ascites with the alfapump offers a new treatment option for this patient group. So far, there is no systematic analysis of patients with this indication available in the literature. This retrospective analysis offers the possibility to assemble already existing data within a reasonably short time frame. Based on this analysis, a prospective analysis can be designed.
Infective endocarditis (IE) is an infection of cardiac valves. IE mainly involves bacteria, more rarely fungi. IE is an uncommon diseases with an estimated incidence of 1-12 cases per 100,000 inhabitants per year. The diagnostic of IE relies on the culture of biological samples (blood cultures and per-operative samples) in the bacteriology laboratory in order to identify the pathogen and its susceptibility to antimicrobials. Nonetheless in about 10% of the cases, the blood cultures remain negative, due to antibiotics taken before harvesting, to non-culturable bacteria or to aseptic phenomena. Clinical metagenomics is defined as the application of high-throughput sequencing (NGS) followed by a specific bioinformatics analysis to obtain clinical information, i.e. pathogen identification and the prediction of their susceptibility to antimicrobials. The metagenome of a sample (i.e. all the genomes of the organisms present) virtually contains all the information necessary for bacteriological diagnosis: what is the pathogenic bacteria , and to which antibiotics it is susceptible. Hence, using clinical metagenomics in the context of IE appears seducing in order to overcome the limitations of conventional methods based on culture. Here, we propose to assess the performance of clinical metagenomics in the diagnostic of IE.
The collected data from the Zurich Registry for pulmonary Hypertension (PH) are evaluated in a retrospective analysis. This study examines the number of patients and their exact diagnoses who are treated at the University Hospital of Zurich and potentially other participating in the Zurich Registry. Other demographic parameters such as age, gender and body-mass-index are also part of the evaluation. Furthermore, the analysis will focus on the newest guidelines on PH. Therefore, it will be checked how many patients would fulfill the therapeutic goals in terms of New York Heart Classification (NYHA), 6-minute walk distance, sign of right heart failure and N-terminal pro-brain-natriuretic peptide(NTproBNP). Additionally, the study examines on how the patients are treated. Despite the different kind of Drugs, the focus lies on the combination therapy (single, double, triple) and the impact the therapy had on the patients.
Motivation represents a core aspect of goal-directed behavior as it determines how much effort individuals are willing to invest to reach their goals. While research on effort-based decision-making focuses mainly on effort preferences in younger adults, loss of motivation might be a key component of the apathetic tendencies frequently seen in older adults. However, an open question refers to which brain mechanisms underlie motivational processes in older adults. The investigators have recently shown that the frontopolar cortex plays a crucial in motivating the exertion of rewarded effort in younger adults. The goal of the current study is to determine whether frontopolar cortex plays a crucial role for motivation also in older adults and may thus be a promising target for improving the motivation deficits in healthy aging. Participants perform computer-based experimental tasks measuring the propensity to exert cognitive or physical effort for monetary rewards. During task performance, participants receive anodal or sham transcranial direct current stimulation (tDCS) over their frontopolar cortex. The study tests whether tDCS over frontopolar cortex allows modulating participants' motivation to engage in rewarded effort.
This is a single center, open label, randomized control trial to assess the efficacy of a one-lead ECG handheld device (Zenicor) for the detection of previously unknown atrial fibrillation (AF) in hospitalized patients. All patients admitted to the internal medicine department of the Hospital Fribourg throughout the study period will be screened for study enrollment. Patients < 18 years, with known or previously documented atrial fibrillation, patients with a cardiac pacemaker, and implantable cardioverter-defibrillator or intra-cardiac monitoring device will be excluded from the present trial. The study population will consist of approximately 800 patients in each group at the University of Fribourg Medical Center. Patients must meet all eligibility criteria for inclusion into the study. Patients allocated to the treatment group will undergo twice daily monitoring with the handheld Zenicor ECG. Additional recordings will be obtained whenever patients notice palpitations. Recordings will be obtained in the presence of specially trained nurses. The recordings will then be validated through a web-based interface offered by Zenicor. The one-lead ECGs will be reviewed by the investigating physicians through the Web-based analysis service (Zenicor-ECG Doctor System) to assess the presence of atrial fibrillation. The primary end point of the study is the percentage of newly detected atrial fibrillation at 6 months
Oral appliances (OA) have emerged as an alternative to continuous positive airway pressure (CPAP) for obstructive sleep apnea (OSA) treatment. The most commonly used OA reduces upper airway collapse by advancing the mandible (mandibular advancement devices, MAD). There is a strong evidence base demonstrating that MADs improve OSA in the majority of patients, including some with more severe disease. However, MADs are not efficacious for all, with approximately one-third of patients experiencing no therapeutic benefit. Patients often prefer MADs to gold-standard CPAP treatment. Head-to-head trials confirm CPAP is superior in reducing OSA parameters on polysomnography; however, this greater efficacy does not necessarily translate into better health outcomes in clinical practice. Comparable effectiveness of MADs and CPAP has been attributed to higher reported nightly use of MADs, suggesting that inferiority in reducing apnoeic events may be counteracted by greater treatment adherence. The MAD in study, called Bite-Velo Linguale (BVL), features a novel monobloc device including a tongue retainer, a suction cavity that maintains the tongue down onto the mouth floor in order to prevent it from raising towards the hard palate, and therefore increasing the retro lingual aerial space. Its design requires the presence of only four occlusal points, allowing for a direct anchorage onto the mandibular bone, thus reducing the risk for occlusal changes, tooth loosening and the development of an anterior cross bite, which represent some of the major long-term adverse effects of oral appliances. MADs are generally well tolerated, although short-term adverse effects during acclimatization are common. Long-term dental changes do occur, but these are for the most part subclinical and do not preclude continued use. The BVL in study features technological advances aimed at preventing long-term dental changes, as well as improving tolerability and easiness of use.
In a randomized, sham-controlled trial the investigators will test whether supplemental oxygen given during cardiopulmonary exercise testing will improve exercise performance and physiological parameters in patients with chronic obstructive pulmonary disease.
