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.
This study is to describe the incidence of infectious meningitis and/or encephalitis, and to analyze clinical, diagnostic and treatment characteristics of patients with suspected (and subsequently verified and not verified) infection.
Datas are lacking concerning weaning from mechanical ventilation for tracheostomized patients. In particular, the effect of different modalities of spontaneous breathing trials on respiratory effort has not been extensively described. This crossover physiology study will include 18 tracheostomized patients ventilated for more than 72 hours. The objective of this study is to compare the effect of three different modalities of SBTs on respiratory effort in tracheostomized patients. The modalities tested are : Pressure Support Ventilation (PSV level 5 cmH2O, PEEP 5 cmH2O), T-piece test and high-flow Oxygen. Each modality is applied in a randomized order, during 30 minutes. During every modality tested, esophageal and gastric pressure, expired CO2, and comfort will be monitored, in addition to standard monitoring. Based on esophageal pressure monitoring, patient's respiratory efforts can be calculated either by esophageal pressure-time product and work of breathing. Pressure generated by inspiratory muscles will also be assessed.
During orotracheal intubation failure in securing an airway can result in serious oxygenation problems. Beside the classic laryngoscopes and fibreoptic scopes, devices with high-resolution video cameras placed in the tip of the devices, were developed and attained in daily routines. Studies and case reports reveal them to be superior in both normal and difficult intubation, especially improving the first-attempt success rate. Latest advancements of the Bonfils fiberscope resulted in the C-MAC VS, which combines rigid and semi-rigid abilities to a rigid video stylet with a flexible tip. Because of its front positioned high-resolution camera resulting in an indirect visualization, it may also have the benefits of video laryngoscopes. Very little data is available on larger numbers of use and the investigators do not know about rare side effects and complications with the use of the device, such as esophageal intubations. Due to its direct view and positioning on vocal cord level, the investigators expect a similar or even lower rate of endotracheal intubation, using the C-MAC VS. The investigators therefore plan to analyze the use of the C-MAC VS regarding its efficiency and safety during airway management in everyday clinical practice. This should provide the evidence about safe use, possible risk factors, rare complications and adverse events, as well as the preferred clinical airway situations to use the C-MAC VS.
The aim of the study is to evaluate the degree of refractive error postoperatively in combined procedures and to calculate a new constant in order to improve current state of the art biometry calculations.
The investigators plan to study the association between physical activity, malnutrition and sarcopenia and the occurrence of acute exacerbations of COPD / the evolution of the COPD assessment test (CAT) over 1 year in a telehealthcare cohort of patients with COPD. The investigators hypothesize that malnutrition and/or sarcopenia at baseline and a decline in the fat-free mass index over time is associated with an increased rate of acute exacerbations of COPD and an increased CAT score meaning a higher risk for mortality, morbidity and impairment of quality of life.
This is a multicenter, open-label, extension study to evaluate the long-term safety, tolerability, and efficacy of treatment with AG-348 in participants who were previously enrolled in Study AG348-C-006 or Study AG348-C-007.
Altered waking states of consciousness and its underlying functional organization have gained increasing interest in recent years, i.e. in identifying the neural basis of consciousness. To overcome fundamental shortcomings of current methods to objectively assess the level of consciousness, the investigators propose here to apply a novel and empirically validated measure called 'perturbational complexity index' (PCI) based on the integrated information theory (IIT). This involves a combination of transcranial magnetic stimulation (TMS) and highdensity electroencephalography (hd-EEG) to measure electrocortical responses as distributed cerebral interactions ('integration') and spatiotemporal pattern ('information'). Given the finding of subjectively expanded consciousness as induced here by psilocybin, the investigators hypothesize that the PCI may be higher in such states. This will be the first TMS/hd-EEG study to investigate quantitatively the level of consciousness in a pharmacologically altered waking state of consciousness.
The aim of the present project is to evaluate the frequency of distant metastases and clinically relevant relapse and mortality, respectively, of aNEN (Neuroendocrine Neoplasms of the Appendix) measuring 1 - 2 cm. The investigators hypothesize that the mortality rate of aNET (Neuroendocrine Tumors of the Appendix) measuring 1 - 2cm is less than 1%. Furthermore, the investigators hypothesize that regional lymph node metastases of aNET measuring 1 - 2 cm are clinically not relevant and are not associated with reduced survival. The investigators therefore hypothesize that oncological right-sided hemicolectomy has no impact on long-term survival after complete resection of aNET measuring 1 - 2 cm and that the malignant potential quo ad vitam of these tumors is lower than the risk of oncological hemicolectomy.
A clinical trial to asses the accuracy, usefulness and usability of a stereotactic image-guidance system during lateral skull base surgery.
This pilot project investigates the use of a structured medication history (Best Possible Medication History, BPMH) in patients (primarily admitted at the emergency department of University Hospital Basel) after transfer to a medical ward. Unintentional medication discrepancies are analyzed comparing outpatient and inpatient medication therapy.
