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.
Management of ACLF is mainly supportive. The poor outcomes lead physicians to consider liver transplantation as an option, even if controversial. In sicker recipients, LT results in immediate survival, but poor medium-term survival rates in some studies. The scarcity of deceased donors obliges to maximize LT success. Alternative strategies, as living-donor LT, should be explored. LDLT has impressive results in Eastern centers, but it is restrained in Western countries, due to potential life-threatening complications in the donor.
Recent literature shows that the sensitivity of the PCR tests for the detection of SARS-CoV-2 using saliva samples is close to that using nasopharyngeal swabs. This type of sampling represents a practical advantage since it can be performed by the patient herself/himself and would thus allow to speed up the collection process. It is also less painful and could prevent the rare lesions to the nasal mucosa that can occur when using nasopharyngeal swabs. Rapid Diagnostic Tests for the detection of SARS-CoV-2 antigens have been developed using nasophayngeal swabs and have shown very high sensitivity against PCR, ranging from 93% to 98% when based on laboratory validation, 80% when based on clinical validation.This method offers the considerable advantage to inform the patient of the test result on site, and allow the provision of appropriate recommendations on the spot of testing. The studies performed so far have been conducted using nasopharyngeal samples only. There are no data with saliva yet. It is expected that the RDT would also work on the saliva. Even if slightly less sensitive due to the fact that it detects antigens and not multiplied RNA as PCR does, RDT on saliva could better serve the public health goal to test widely and quickly and have ultimately more COVID cases detected and isolated, and hence reduced transmission. To investigate the case detection rates of both PCR on saliva and nasopharynx and RDT on nasopharynx and saliva, the patient will be taken four samples, two swabs on saliva, one for RDT and one for PCR, and two swabs on nasopharynx, one for RDT and one for PCR. Patients who have at least one of the common symptoms and who consent to such a procedure will be recruited to compare the four results. The primary objective is to compare the case detection rates for SARS-CoV-2 of the four testing methods (two sampling types and two test types).
Injured brain tissue supplied by a disturbed state of cerebral autoregulation (CA) is at risk of secondary ischemia, e.g. in patients with stroke, subarachnoid hemorrhage, intracerebral hemorrhage or bacterial Meningitis. Up to now, there is lack of a simple and easy to perform bed side test that would allow for to intervene when CA failure is indicated. For this purpose, we explore the dynamics of the interplay between blood pressure and cerebral blood flow velocity using transcranial Doppler ultrasound (or near infrared spectroscopy derived haemoglobin concentration changes) as a measure of CA. To describe these dynamics different mathematical models are used, but they all still need validation and proof of concept because these dynamics are poorly understood with respect to the factors which influence the composition of the mathematical models. Objectives: To what amount is CA disturbed in the different stroke subgroups ? Is a disturbed CA a risk factor of poorer outcome ?
The aim of this project is to measure behavioural disorders in Parkinson's disease (PD) patients in a more objective way, in order to facilitate the detection of those symptoms and improve the treatment of non-motor symptoms in Parkinson's disease.
The Ear-Nose-Throat (ENT) Prospective International Cohort of patients with Primary Ciliary Dyskinesia (EPIC-PCD) is a prospective observational clinical cohort study, set up as a multinational multi-centre study. It is embedded into routine patient care of participating reference centres for PCD and patients keep being managed according to local procedures and guidelines.
The cochlear implant is a neural prosthesis and has been the gold standard treatment for severe to profound sensorineural hearing loss over several decades. The surgical procedure for cochlear implantation aims to atraumatically insert the electrode array of the cochlear implant into the cochlea. However, due to the location of the cochlea inside the skull, the surgeon is required to create an access from the surface of the temporal bone to the cochlea (inner ear). In conventional methods, this access is acquired by removal of portions of the mastoid bone through a mastoidectomy and posterior tympanotomy. The outcome and success of the conventional procedure varies due to mainly two factors: surgeon skill and subject anatomical variation. To overcome these variables toward a more consistent and less invasive cochlear implantation surgery, the development of robotic and image guided cochlear implantation has taken place. This study primarily aims to explore the performance of robotic cochlear implantation surgery.
This study will investigate the accuracy of implant navigation for spinal instrumentation. The tested technique is based on commercially available AR-glasses and a specially developed software component
The purpose of this study is to assess the effect of Dexamethasone on postoperative pain and nausea after hip arthroscopy.
In this clinical trial, an un-controlled, repeated measures open design with within-subject comparison will be used to evaluate the effect of the device under investigation on sound perception. This design was shown to be successful in previous studies for the evaluation of sound coding strategies. Furthermore, a within-subject comparison decreases the variance in the results allowing for fewer subjects when the population using the investigational device is not large in general.
Patients hospitalized at the clinic Cecil who need telemetry will be monitored for 48 hours with the SmartCardia system in addition to conventional monitoring.
