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 interventional part of the study aims to assess the acute effect of the Brain2Business (B2B) tool on creative thinking (primary objective) in adults with psychological disorders. Additionally, the study assesses the B2B effects on energy-related sensations and metabolism, technique adherence, gratefulness and goal-directed activation (secondary objectives) in adults with and without psychological disorders. The observational part of the study primarily aims to investigate the link between psychopathology, intelligence, energy-related sensations and metabolism validating the "c factor mito-bioenergetics" (CMB) model in a sample of adults with and without psychological disorders.
This retrospective, monocentric study aims to examine risk factors for postpartum hemorrhage in women with histologically verified placenta accreta. Women with histologically verified placenta accreta are divided into two groups: women with normal blood loss (BV < 500 ml) versus women with increased blood loss (BV ≥ 500 ml). The clinical data of pregnant women with histologically verified placental disorders, who gave birth in the Women's Clinic University Hospital Basel (USB) between 1986 and 2019, are compared with each other.
This retrospective single-centre study aims to examine the success rate of concomitant surgical ablation in patients with atrial fibrillation (AF) with an up to eight years follow-up period. Moreover, the focus of this study was to identify variables which predict freedom from AF, such as the type of AF, lesion set performed, energy source used and the patient's characteristics.
This retrospective collaborative study on persistent exercise intolerance after COVID-19 offers to perform a large descriptive analysis of CPET performed in real-life by pulmonologists, cardiologists and physiologists. Indeed, these practicians are regularly consulted for a persistent intolerance to exercise expressed by dyspnea and/or frank fatigability sometimes associated with muscular or thoracic pain. When these complaints persist beyond 3 months after the first symptoms, it is legitimate to perform a CPET: - Either to evaluate the functional impact of an identified organ deficiency (e.g. myocarditis, pulmonary fibrosis, etc.), - Or, in the absence of formal arguments for an identified organ deficiency, to observe possible abnormalities in physiological responses during an incremental exercise test, likely to explain the persistence of symptoms and intolerance to exercise. Indeed, the recent literature highlights the presence of non-specific ventilatory and cardio-circulatory abnormalities leading to various physio-pathological observations. Unfortunately, these reports now concern relatively small numbers of patients with very diverse clinical forms of Covid, comorbidities and habitus. In order to improve the understanding of persistent symptoms and in particular the diversity of physiological response presentations, the investigators propose to collect a very large amount of data through a web-based platform designed to collect the measurements made throughout the exercise test directly from the ergospirometer. The relevant data covers the period from January 2, 2020 to December 31, 2022 (i.e. 35 months), The retrospective data collection will be carried out from February 1, 2023 to December 31, 2023. The descriptive analysis will focus on the kinetics of all the variables measured and calculated on subgroups defined a priori on age, sex, comorbidities, acute covid severity, persistent symptoms post covid, regular habitual physical activity level, etc. according to the sample. The study is expected to collect data from around 1000 patients and to involve around 40 French-speaking investigators. However, this collaborative study is open on request to all centers wishing to participate, as the web platform has been developed for data collection in English.
The aim of this study project is to clarify whether defined practical application skills are learned by anesthesiology specialists through a self-directed learning program with learning videos and a hands-on exercise station ("intervention group"). "Control group" is a traditional instructor-led practical workshop classroom teaching. Hypothesis: A video-based and self-directed learning program shows no difference in the learning successes than traditional face-to-face workshops.
End-ischemic hypothermic oxygenated machine perfusion (HOPE) of human donor livers mitigates ischemia-reperfusion injury, resulting in a reduction of post-reperfusion syndrome, early allograft dysfunction and biliary complications, when compared with static cold storage. According to IDEAL-D (Idea, Development, Exploration, Assessment, Long term study-Framework for Devices), with several published randomized controlled trials on short-to-medium term outcomes, scientific evidence for HOPE has currently reached stage 3. Assessment of long-term outcomes after HOPE preservation based on real-world data (i.e., IDEAL-D stage 4) is currently still lacking. Therefore, we aim to conduct an international, multi-center, retrospective, observational cohort study to assess long-term outcomes after transplantation of donor livers preserved by hypothermic oxygenated machine perfusion (HOPE).
Ethical research on detained persons remains limited, including research on informed consent. This study aimed to fill in this research gap and compared audio-visual and paper-based materials for a one-time general informed consent for research in prison, using a randomized design. The primary outcome was whether participants sign the inform consent. Secondary outcomes included understanding, evaluation, and time to read/watch the informed consent.
This study is a non-blinded single armed pilot study aiming to apply a newly created medical device in patients with seventh nerve palsy suffering from lagophthalmus in order to determine the best way for neuromuscular stimulation of the orbicularis oculi muscle and facial nerve in order to enable eyelid closure (blink). Initially, a tailored external neurostimulation prototype will be created in collaboration with the ETH for patients with facial nerve palsy and lagophthalmos. Aim of this study is to create an efficient, safe and comfortable medical device that can achieve an effective blinking through external electrical neuromuscular stimulation of the orbicularis oculi in patients with facial palsy and lagophthalmos. Such a device can become an essential part of facial palsy treatment.
Isolated vertebral artery occlusions (VAO) account for approximately one third of posterior circulation occlusions, but have been given the least attention among posterior circulation strokes. If the two recent ATTENTION and BAOCHE randomized clinical trials have proven the superiority of endovascular thrombectomy (EVT) in basilar artery occlusions, data on the effectiveness and harm of acute revascularization treatment on isolated VAO is scarce. We aim to investigate the impact of acute recanalisation treatments in acute ischemic stroke patients with isolated VAO. In the absence of RCT, observational data with appropriate statistical methods may give indications on benefits and harms of treating neglected stroke situations like acute vertebral occlusion. Results may also lay the basis for prospective studies, such as randomized clinical trials.
Osteoporotic fractures are associated with significant morbidity, increased mortality and reduction in the quality of life, available treatments reduces the fracture risk between 30 and 70%, however some patients experience a new fracture and/or continue to loose bone during treatment; this has been defined as treatment failure (TF). The epidemiology and biological bases of TF are currently under-investigated, thus it is impossible for the physician to forecast patients' answer to treatment. The aims of TAILOR study are to collect sounded epidemiological data on TF in a real life setting. To this extent, the investigators will retrospectively a large cohort of 5000 patients with at least 60 months of anti-osteoporotic treatment followed in our center for the diagnosis and care of bone metabolic diseases, and compare TF patients to adequate responders (ARs) for clinical characteristic and biological parameters. The results will be a "signature" to identify those patients who will experience TF.
