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.
Objective: Investigators aimed to evaluate the impact of a high resolution standardized laparoscopic (HRSL) cholecystectomy protocol on operative time and intraoperative interruptions in a teaching hospital. Background: Interruptions of the surgical workflow or microcomplications (MC) lead to prolonged procedure times and costs and can be indicative for surgical mistakes. Reducing MC can improve operating room efficiency and prevent intraoperative complications. Methods: Audio video records of laparoscopic cholecystectomies were reviewed regarding type, frequency and duration of MC before and after the implementation of a HRSL which included the introduction of a stepwise protocol for the procedure and a teaching video. After consent operating team members were obliged to prepare the operation with these resources.
The purpose of this study is to see if BMS-986205 combined with nivolumab, compared to nivolumab by itself, is more effective in treating Melanoma that has spread or is unable to be removed by surgery, and has not previously been treated
Anemia prevalence in orthopedic surgery is up to 30 %. Identifying those patients prior to surgery and treating them would be ideal. Different ways of determining hemoglobin Levels are available. In this study classical laboratory determination, determination with HemoCue® and Rad-67™ will be performed to compare precision of those three methods as well as their correlation.
Young adults who do not successfully transition from compulsory education to upper secondary level are at increased risk of developing mental illness, as compared with their working peers. The causality is unclear: they are either unable to find a job due to a pre-existing mental illness, or their failure in finding a job has contributed to the mental illness. The Zurich University of Applied Sciences has developed an innovative intervention that includes psychotherapeutic support in a work integration programme. Recognising and treating mental illness early increases the chances of a successful transition to the labour market.
Perimetry is a well-established method that is used to measure the visual field functions of humans. Commercially available products, such as the OCTOPUS 900 (Haag-Streit AG, Koeniz, Switzerland), are commonly used for assessing the visual field. Such devices are of critical value for patients suffering of glaucoma and neuro-ophthalmic conditions. The operating principle is to sequentially present light stimuli of different intensity at different locations within the visual field in an automatic way. Algorithms that select what locations and intensities to present over time are called strategies. These have the goal to provide both a fast and accurate estimation of the visual field function. Recently, new strategies were developed that are faster and equally accurate as the strategies used today. The technological advancement of these new methods lies primarily in the ability to estimate location sensitivities without observing them directly but by leveraging previously queried locations. For this the investigators plan to implement the next generation of perimetry strategies into an OCTOPUS 900 and to test it in healthy subjects and glaucoma patients.
Rationale: According to the WHO, iron deficiency is still the most common and widespread nutritional disorder in the world. Current iron supplements have limitations in terms of bioavailability and tolerability. Prebiotic fibers, such as galacto-oligosaccharides (GOS), selectively enhance growth of beneficial colonic bacteria. Prebiotics in general enhance the production of short-chain fatty acids (SCFAs) and thereby decrease luminal pH. Through the reduction in colonic pH, prebiotics can enhance absorption of minerals such as calcium and magnesium and they have been proposed to potentially improve iron absorption as well. The primary objective of this study is to investigate the effect of an addition of GOS to an iron supplement on iron absorption in iron deplete, healthy, normal weight women.
The purpose of this study is to evaluate the efficacy and safety of pembrolizumab plus epacadostat compared to pembrolizumab plus placebo as first-line treatment in participants with metastatic non-small cell lung cancer (NSCLC) expressing high levels of programmed cell death ligand 1 (PD-L1).
In this pilot study a new surgical treatment approach for perianal fistulae, called Fistulodesis, is performed. The study aims to assess effectiveness, safety and tolerability of the Fistulodesis procedure. The investigators are aiming to include 20 patients with Crohn's disease and 20 patients without underlying Crohn's disease. It is an open label study with an anticipated duration from January 2017 to January 2020.
Serotonin receptors, especially the 5HT2A receptor, are thought to be involved in the effects of various recreationally used psychedelic substances such as LSD. LSD potently stimulates the 5-HT2A receptor but also 5-HT2B/C, 5-HT1 and dopaminergic receptors. LSD induces acute transient alterations in waking consciousness including visual perceptual alterations, audio-visual synesthesia, derealization and depersonalization. LSD has therefore been used as experimental tool ("psychotomimetic") in modern psychiatric research to study psychotic-like states and model psychosis in healthy subjects [1-5]. However, the dose-effects of 5-HT2A receptor stimulation by LSD has not yet been studied. Additionally, there is still very limited data to what extent the 5HT2A receptor contributes to LSD's effects and its role in the mediation of the full response to LSD at a high dose is unclear. A recent experimental human study showed the 5-HT2A receptor antagonist ketanserin fully blocked the subjective effects of a moderate dose of 100 µg of LSD [6]. But, whether the effects of a high 200 µg oral dose of LSD can be blocked by the selective pharmacological 5-HT2A antagonist ketanserin remains to be tested to confirm the critical role of the 5-HT2A receptor in more pronounced alterations of consciousness and perception. The present study therefore explores the role the 5-HT2A receptor in LSD-induced altered states of consciousness using escalating doses of LSD and the 5-HT2A receptor blocker ketanserin administered before a high dose of LSD.
Patients using multiple drugs including generics have found different solutions to manage their medication. During a Polymedication-Check (medication review type 2a service in community pharmacies) additional information about the organisation of patients' medication in daily life will be compiled in Swiss community pharmacies. Data will allow to better address patients' needs in their medication organisation and comprehension of generics.
