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 retrospective observational cohort study is to assess and analyze clinical, electroencephalographic, laboratory, comorbidity, and treatment characteristics of Intensive care unit (ICU)-patients with epileptic seizures and to subsequently compare their characteristics with ICU-patients with status epilepticus (SE).
This observational study investigates whether 3 paints are superior compared to 2 paints in reducing microbial skin counts in the disinfection area of cardiac and abdominal surgery patients.
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.
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.
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.
This study evaluates the diagnostic value of the addition of indocyanine green and near infrared fluorescence imaging during laparoscopy in patients with suspected endometriosis.
The hypothesis of this study is that there are people running following a total knee arthroplasty (TKA). The objective is (1) to determine if there are people that ran/run following their TKA and (2), in case (1) is true, to identify some general running parameters such as duration, frequency, perceived barriers for running. Patients with a TKA and a score equal or higher than 9 on the UCLA activity scale at any time between 2 years prior to surgery and at present will be invited to participate in the trial by phone. All these patients will receive the study's information form and questionnaire by post with a pre-stamped envelope to return the documents.The survey was created and piloted internally for this study. There are 21 questions, most of them are "yes or no" and some others open questions to assess parameters such as duration of difficulties faced. The questionnaire is composed of three parts. The first part is interested in the preoperative activity (during the 2 years before surgery), the second part in the postoperative activity (during the 2 years after surgery) and the third part refers to the current practice. For each part, people are asked about specific practice parameters and modalities. Furthermore, we seek to determine whether there was/is a willingness to run following TKA, if patients receive any education/information about it and their personal attitudes towards running with a TKA. The anonymized data will be collected by the main author for subsequent analysis.
Fluid treatment is usually performed with either balanced crystalloid fluids or iso-oncotic colloids, (synthetic colloids, plasma and 5% albumin). Doubts have been raised about synthetic colloids (impairment of renal function and coagulation), and the natural albumin has been used more extensively. Albumin is the main protein responsible for plasma oncotic pressure and its volume expansion effect. An alternative therapeutic option is the mobilization of tissue fluid by infusing a small amount of hyper-oncotic fluid like the 20% albumin solution (endogenous fluid recruitment). The primary objective of this study is to test the effect of 20% albumin on plasma volume expansion and fluid recruitment in the frame of blood loss replacement during cystectomy using established fluid kinetic models. The investigators expect that fluid replacement with crystalloid will be better sustained intravascularly with the administration of 20% albumin and be able to recruit fluid into the vascular compartment.
Food & You is a large-scale citizen science research project in Switzerland. With this project, the researchers want to confirm that individuals respond differently to food, that is, that the blood sugar response (the level of sugar in the blood after a meal) varies among individuals, even after consumption of the same food or beverage. Secondly, the researchers want to develop an algorithm that will predict the individual blood sugar response and provide personalized diet recommendations.
