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.
With the project Smart Muscle for Incontinence Treatment (SMIT) a multidisciplinary consortium consisting of representatives ranging from clinical medicine via microelectronics towards biomaterial science aims to develop a novel implant to treat faecal incontinence. The aim of this campaign includes development of implantable prototype devices acting as artificial continence muscles using low-voltage electrically activated polymers (EAPs) controlled by implemented pressure sensors and the patient. Subsequently, the knowledge of the anatomical and biomechanical properties of the anal sphincter complex are of cardinal importance. Most of the existing data on anatomy and physiology results is based on old studies and almost no data on biomechanical properties are available. However, new technologies or even merging data from different examination methods might provide new information in this field.
This study will be carried out as a retrospective, non-interventional observational review of medical records for patients in multiple countries with platinum-sensitive recurrent serous ovarian cancer. The objectives are to describe in a real-world population, treatment patterns, BRCA mutation testing and results, overall survival, health care utilization and also to estimate rates of selected treatment- and/or disease-related side effects
Randomized, multicenter trial to evaluate the cost-effectiveness of 2 different follows up programs in head and neck cancer survivors. Patients in complete remission at month 6 (+/- 1 month) after curative treatment will be randomized in two arms according to 2 different follow up approaches: Non Intensive Follow up approach (Arm A) with no radiologic evaltuations scheduled, but required only at the occurence of any signs or symptoms and Intensive Follow up approach (Arm B) with scheduled radiologic evaluations.
The investigators are undertaking the first European Randomised Controlled Trial (RCT) for epilepsy surgery in children with FCD type II, to prospectively evaluate the role of the KD prior to surgery in improving seizure outcome. The investigators will evaluate the role of KD as a disease-modifying treatment to achieve seizure control and improve neurodevelopment and quality of life. Children age 3 - 15 years with pharmacoresistant epilepsy believed to be the result of focal cortical dysplasia type II, considered to be surgically treatable, will be randomised to either receive 6m treatment presurgery with a ketogenic diet, or to proceed direct to surgery (no pretreatment). Primary outcome will be the time to achieve a period of 6 months of seizure freedom from the date of randomisation. Tissue resected at surgery will also be evaluated with regard to the degree of any methylation of DNA.
Femoral component rotation in total knee arthroplasty (TKA) has been considered an important factor for outcome. However, measurement of femoral component rotation is difficult to perform. Femoral TKA component rotation can be assessed on special radiographs (Kanekasu technique), axial CT slices and 3D reconstructed CT images. It was the hypothesis that measurements on radiographs are comparable to measurement on CT images. Measurements of femoral TKA rotation will be measured three times by three different observers and inter- and intraobserver reliability is calculated. The absolute values of each measurement method is noted in degrees.
Spontaneous intracerebral hemorrhage (ICH) remains a devastating disease with mortality rates up to 52% at 30 days. It is a major public health problem with an annual incidence of 10-30 per 100'000 population, accounting for 2 million (10-15%) of about 15 million strokes worldwide each year. The strategy of decompressive craniectomy (DC) is beneficial in patients with malignant middle cerebral artery (MCA) infarction. Based on the common pathophysiological mechanisms of these two conditions, this procedure is also frequently performed in patients with ICH, but is has not yet been investigated in a randomized trial. The primary objective of this randomized controlled trial is to determine whether decompressive surgery and best medical treatment in patients with spontaneous ICH will improve outcome compared to best medical treatment only. Secondary objectives are to analyze mortality, dependency and quality of life. Safety endpoints are to determine cause of any mortality and the rate of medical and surgical complications after DC compared with best medical treatment alone.
Efficacy of transitional case management following psychiatric hospital discharge: a randomized trial Background The movement of deinstitutionalisation in Western societies has modified the role of psychiatric hospital, which has lost its asylum function to become a place for acute care. Psychiatric stays are now shorter and close interactions with the outpatient care network is therefore more critical than before. The first weeks following discharge from psychiatric hospital represent a period of high risk for relapse, readmission or even suicide. Case management has a proven efficacy in facilitating patients' deinstitutionalisation after very long hospitalisations and in stabilizing high users of psychiatric care. In contrast, studies exploring the impact of time limited case management following discharge from short stays (transitional case management) in earlier phases of psychiatric disorders in connection with primary care are lacking. Working Hypotheses The investigators hypothesize that transitional case management following hospital discharge decreases risk of readmission, improves adherence to outpatient care, facilitates recovery and improves patients' satisfaction with treatment as compared to routine care. Specific Aims In this study, the investigators will compare the impact of both intervention on number of contact and level of adherence to outpatient care. The investigators will also compare both groups on number of readmission, risk of early aggravation of the disorders, level of functioning and satisfaction with care. Methods This is a randomized single-blind study comparing transitional case management after discharge with routine post-hospitalization care for subjects living independently without institutional psychiatric follow-up. Demographic and clinical data will be gathered during hospitalization, and 1, 3, 6 and 12 months after discharge. Quantitative assessment of outcomes using validated instruments will be: contact and level of adherence to outpatient care (primary outcomes), as well as number of hospitalization days, number of readmissions, severity of illness and satisfaction with care (secondary outcomes). Expected Value of the Proposed Project This study should improve psychiatric patients follow-up in collaboration with the different levels of care in the global context of deinstitutionalization.
Due to successes in the last decades in pediatric heart surgery and cardiology, 90-95% of the children with congenital heart disease reach adult age.This results in an increasing number of adults or "grown-ups" with congenital heart disease (ACHD or GUCH patients) that require special health care organization and training programmes. Long term complications of these GUCH patients and optimum treatment strategies are still poorly known. The aim of this registry is to collect quantitative and qualitative data regarding GUCH patients treated in specialised centres in Switzerland.
BACKGROUND: Surgical injury and inflammation provoke a stereotypical stress response. Insulin resistance plays an intriguing role in these metabolic alterations and depends on the intensity of injury. Metabolic derangements resulting from peripheral insulin resistance are unambiguously related to adverse outcomes and higher perioperative complication rates. Therefore, insulin resistance offers to act as a marker for stress and is potentially relevant in predicting clinical outcome. Plasma-glycosylated hemoglobin A (HbA1c) is an established indicator for blood glucose control and has a prognostic value regarding outcomes after major surgical interventions. Adipose tissue holds a key function in endocrine metabolism by releasing multiple substances, so-called adipose-derived secreted factors or adipokines. Recent studies have linked several adipokines to overall insulin sensitivity in metabolic syndrome-related conditions as well as in critical illness. Irisin, a recently identified myokine acts on white adipose tissue and plays a role in the prevention of insulin resistance. AIMS OF THE STUDY: The aim of this study is to assess the level and the effects of perioperative insulin resistance on clinical outcome in cardiac surgery patients. Based on previous studies suggesting glucose homeostasis and insulin resistance are associated with severity of illness and outcome in critically ill patients,it is proposed that patients with marked insulin resistance suffer from worse clinical outcome. This study protocol evaluates the ability of homeostasis model assessment (HOMA), quantitative insulin sensitivity check index (QUICKI), HbA1c, the adipokines Angiopoietin-like protein 2 (ANGPTL2), C-X-C motif chemokine 5 (CXCL5), and visfatin, and the myokine irisin to indicate perioperative insulin resistance and explores for correlation with adverse clinical outcomes after 30 days. MATERIAL & METHODS: 325 patients admitted to the surgical intensive care unit after elective on-pump cardiac surgery will be consecutively enrolled. Baseline characteristics and routine blood samples will be assessed the day before surgery. Study blood samples will be drawn preoperatively in the induction bay of anesthesia to measure the insulin resistance indices HOMA and QUICKI, HbA1c, ANGPTL2, CXCL5, visfatin, and irisin. Blood glucose, irisin, adipokines, and routine biochemical tests will be assessed upon admission to the intensive care unit and on postoperative days 1 and 3. Adverse outcomes will be assessed 30 days after surgery. Sample size is set to ensure at least 80% power at a significance level of 0.05.
