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 clinical trial aims to evaluate the efficacy of fecal microbiota transplantation (FMT) after standard of care treatment (either vancomycin or fidaxomicin) vs the pragmatic use of standard of care treatment (either vancomycin or fidaxomicin) in severe and non-severe first episode and first recurrence of Clostridioides difficile infection (CDI). Experimental arm: antibiotic treatment (vancomycin or fidaxomicin as initially prescribed per SoC continued for 10 days) followed by FMT by oral capsules (one FMT, i.e. 20 FMT capsules given on 2 consecutive days, and followed by a 2nd FMT in severe CDI). Control Arm: vancomycin or fidaxomicin as initially prescribed per SoC continued for 10 days.
The primary research project objective is to investigate whether a maltodextrin with high degree of polymerization (Roquette Glucidex 2) and a dextran with comparable degree of polymerization (Pharmacosmos Dextran 10) have lower post-prandial glucose response than glucose syrup (Roquette Glucidex 40). To confer further robustness to the results, the post-prandial glucose response will be compared to a negative control represented by a resistant dextrin with a complex structure containing 70% non-digestible dietary fiber (Promitor 70), which is currently used for sugar replacement. Additional key objective is to investigate the safety and gastrointestinal tolerability of the investigational products.
This retrospective study is to determine whether age is a risk factor for postoperative complications in patients undergoing transforaminal lumbar interbody fusion; specifically whether the risk (odds) of implant failure and the need for revision surgery increases with age.
This retrospective study is to analyse microbiological cultures from the sonication fluid of the explanted prothesis to detect bacteria in the biofilm on the implant surface and to investigate whether the number of bacteria in the biofilm correlates with the duration of the PJI respectively with the period between symptom onset and date of revision surgery.
The primary goal of the study is to assess ultrasonographic Power Doppler signals after ultrasound-guided puncture and lavage of rotator cuff calcific tendinitis of the shoulder. Secondary outcomes are sonographic features like the course of residual calcific material and the course of tendon healing als well as the clinical symptoms of the patient.
This study is to review the the effect of PTH on the outcome of spinal fusion surgery by analyzing the procedure with Forsteo (PTH) previously used in the University Hospital Basel and the Endonet Clinic, as part of a retrospective, observational study.
The impact of hypoxia on maximal work rate during incremental ramp exercise within 3-6 hours after arriving at 2500m of high altitude in patients with precapillary pulmonary hypertension
CYP2C19 is responsible for the metabolism of approximately 10% of drugs currently on the market, including several proton pump inhibitors, clopidogrel, benzodiazepines and some tricyclic antidepressants, including amitriptyline. It is a cytochrome whose activity is characterized by a great variability in the general population. This variability can be explained, in part, by genetic and environmental factors The classification of phenotypes associated with CYP2C19 has evolved over time. Today, five distinct phenotypes are used to characterize this variability: the slow metabolizer (SM) phenotype, the intermediate metabolizer (IM) phenotype, the normal metabolizer (NM) phenotype, the fast metabolizer (RM) phenotype and finally the ultra-fast metabolizer (UM) phenotype. (UM) phenotype. Although directly measurable with test substances, CYP2C19 phenotypes are often assigned on the basis of genotype. They may be impacted by intrinsic (e.g., comorbidities) or extrinsic (e.g., co-medications) factors. Phenoconversion or phenotypic change is the phenomenon by which an individual switches from one phenotype to another due to an environmental influence such as a drug interaction. However, genotype is likely to influence the degree of response to a drug interaction. Vulnerability to phenoconversion therefore differs according to the genotype of the individual. The purpose of our study is to determine whether individuals genetically MR, NM and IM have the same vulnerability to phenoconversion. Thus, the magnitude of the response to CYP2C19 inhibition will be studied in these 3 groups of individuals (NM:*1/*1, RM:*1/*17 and IM:*1/*2-*2/*17). Inhibition will be studied in two steps, using a strong (fluvoxamine) and a weak (voriconazole) inhibitor of CYP2C19.
Musculoskeletal aging is one of the major responsibilities and challenges for public health. In particular, sarcopenia correlates with an increased risk of falls and increased morbidity and mortality. With regard to screening for sarcopenia, the guidelines of the European Working Group on Sarcopenia in Older People (EWGSOP2) refer to algorithmic case finding, diagnosis, and quantification of the severity of sarcopenia in clinical. While functional measurements are more difficult to standardize and associated with higher variability, Dual-energy X-ray absorptiometry (DXA) is considered a highly accurate method, even referred to as the "gold standard" to determine muscle mass in the scientific literature. Nevertheless, DXA, which is routinely used, shows inconsistent correlation with functional decline in muscle strength. Another method of muscle quantification is bioelectrical impedance analysis (BIA), a simple, portable instrument that is more readily available and applicable due to its lower cost. However, it tends to overestimate muscle mass and is also more susceptible to a person's hydration status. Because of these difficulties, recent research has focused on the potential of using shear wave elastography. This method indirectly serves to quantify the rapid type II muscle fibers in order to make statements about the muscle quality because an age-related decrease in type II muscle fibers is associated with a more frequent fall frequency. First, the investigators will define three different categories according to the EWGSOP 2 guidelines based on the muscle strength (grip strength, assessed by pneumatic hand dynamometer) and muscle mass (Appendicular skeletal muscle mass, assessed by BIA): "No Sarcopenia", "Probable Sarcopenia" and "Confirmed Sarcopenia". Within these categories, the Investigators would like to establish a multivariate data analysis of different functional measurements with quantitative imaging results. This exploratory trial design is intended to improve understanding within the three categories and to test proxy measurements of different patients who are ruled out for common routine measurements due to, for example, cognitive impairment or pre-existing rheumatic disease. This is essential to consider the heterogeneity of the aging society proportionally.
This is a monocentric prospective, randomized, double-blind placebo-controlled study. It is designed to evaluate the superiority of the rTMS over sham treatment of depressive symptoms in the context of dementia. It is aimed at a population ≥ 65 years old, with affective BPSD. We wish to recruit 44 participants, with an estimated rate of potential drop out of 20%. Patients will be randomly assigned to the sham or rTMS group. The sham stimulation reproduces the procedure in all the steps, has the same duration and differs exclusively by the device setting. After inclusion, both groups will receive 15 sessions distributed over 5 days a week for 3 weeks
