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 purpose of this randomized controlled trial is to compare clinical data and implant stability of immediately loaded TSIII Osstem implants with Sandblasted and Acid-etched (SA) surface versus implants with SA surface modified with pH buffering agent for the rehabilitation of single implant-supported crown.
This registry is being conducted to support ongoing post-market surveillance activities.
This study is to create a self-learning software that can detect acne lesions. Patients take a picture of their face every single day for 3 months with a secure mobile phone and fill out a pre-designed questionnaire. After 3 months, the mobile will be collected back and the pictures will be evaluated by 3 dermatologists. The software is able to learn from the dermatologists' evaluation and -using machine learning- a mechanism that should be able to automatically detect acne to some extent will be established.
The objective of this study is to better understand the structural and functional changes that the CNS undergoes following stroke and how these changes relate to clinical measures. Both macroscopic and microscopic changes of the brain and the spinal cord will be examined in stroke patients and compared to healthy controls. In terms of structural plasticity, we aim to identify MR biomarkers that allow predicting the course of the patient's neurological status and accurately describe the course of the disease and the recovery. Importantly, we aim to investigate which factors scale the patients' symptoms. In terms of functional plasticity, we will combine fMRI with behavioural motor and sensory testing to understand i) the structural and functional interplay between spinal and supraspinal neural circuits after stroke possibly driven by beneficial plasticity/regeneration vs. maladaptive plasticity/degeneration and ii) which clinical and behavioural determinants drive functional hand representations in the primary somatosensory and motor cortices to be maintained and which determinants drive reorganisation of functional representations following sensory input loss. We will further investigate the contribution of brainstem reorganisation to plasticity observed at the cortical level and, by doing so, aim to better understand the mechanistic underpinnings of functional reorganisation.
Sepsis, a multi organ failure caused by infectious diseases, is a major health burden with an average mortality rate of 26%. Cells of the innate immune system of hosts recognize specific patterns of pathogenic bacteria and trigger an inflammatory response. In case of sepsis, this inflammatory response takes a deregulated course, expressing an overwhelming amount of pro-inflammatory cytokines leading to a loosening of endothelial tight junctions, evasion of intravasal fluids and proteins into the interstitium, as well as direct tissue damage throughout an overproduction of reactive oxygen species by neutrophils. These pathological changes of the host's proper immune system lead to a multi organ failure, which characterize a clinical pathomechanism of sepsis. Several studies confirmed an immunomodulatory effect of sevoflurane's primary metabolite hexafluoroisopropanol (HFIP) attenuating pro-inflammatory cytokine expression with a consecutive improvement of organ function and survival in rodent models of sepsis. Until now, there are no data available confirming this effect in septic patients as well. With this study, the direct impact of sevoflurane's primary metabolite HFIP on cytokine expression in the blood of septic patients will be investigated for the first time.
The purpose of this study is to continue to assess safety and tolerability, and to allow continued access to study treatment for subjects already receiving spartalizumab as single agent or in combination with other study treatments.
The project investigates the situation of patients with chronic pelvic and chronic belly pain before and after our group therapy.
Laser surgery and radiotherapy are well-established standards of care for unilateral stage 0 & I carcinoma in situ (Cais) and squamous cell carcinoma of glottic larynx (SCCGL). Based on meta-analyses, functional and oncological outcome after both treatment modalities are comparable1-5. However, no properly conducted randomized trials comparing these treatments exist. The only such trial with the endpoint of voice quality had to be prematurely closed due to low accrual6. The traditional radiotherapy involves the treatment of the whole larynx. Recently, a new radiotherapy technique was introduced by a team of researchers from Netherlands, where the treated target volume consists of involved vocal cord and therefore 8 to 10-fold smaller than the target volumes used for traditional whole larynx irradiation. The treatment is reduced to 16 fractions which corresponds to 3 weeks and a day7-12. The results of a prospective cohort (n=30) with single vocal cord irradiation (SVCI) were compared with the results of a historical prospective cohort previously treated with whole larynx radiotherapy (n=131) in the same institute. The median follow-up was 30 months. The voice handicap index (VHI) at all time points beginning from the 6th week after SVCI was significantly superior to the same time points with conventional radiotherapy. Moreover, a comparable local control with SVCI (100%) vs. conventional radiotherapy (92%) was reported at two years, p=0.2412. Based on this information, the investigators' main aim is to compare SVCI to Transoral CO2-Laser Microsurgical Cordectomy (TLM) with the main focus of patient-reported voice quality.
The present study is a monocentric, observational, single arm, study, with the aim to determinate the ability of FFR-CT to exclude or confirm the presence of hemodynamically significant coronary stenosis, compared to coronary angiography in high-risk acute coronary syndrome patients.
Background: In Switzerland, about 6000 individuals live with the consequences of a spinal cord injury (Brinkhof et al, 2016). One of the major goals after an incomplete spinal cord injury (iSCI) is to regain walking function. To this end, different approaches are used in rehabilitation such as treadmill-based, robotic-assisted (exoskeleton or end-effector) and conventional gait training. According to current literature, the superiority of one of these approaches remains unclear (Mehrholz, Harvey, Thomas, and Elsner, 2017); In the research on gait rehabilitation after iSCI, recent randomized clinical trials (RCTs) found no statistical differences between conventional gait training and robotic-assisted gait training. Nevertheless, according to the comparison of effect sizes obtained from these training, these trials suggested that the conventional training approach leads to larger improvements in gait capacity when compared to robotic-assisted therapy (Field-Fote and Roach, 2011; Nooijen, Ter Hoeve, and Field-Fote, 2009). Therefore, these trials highly recommended further research considering these aspects. However, in clinical settings, the implementation of such systematic and intense training sessions remains challenging. The present study aims to test the hypothesis that conventional training might have larger effect sizes on gait capacity and to evaluate the feasibility of such systematic training in a clinical setting of inpatient rehabilitation. Objectives: To contribute to the current knowledge on best clinical practice in gait rehabilitation within the iSCI population. More specifically, the study objectives are two-fold: A first objective is to compare the effects of conventional training, end-effector based therapy and the combination of these interventions on the gait ability of iSCI. A second objective is the evaluation of the feasibility of systematic gait training protocols in a clinical setting. Participants: Individuals with motor incomplete spinal cord injury (iSCI), presenting a traumatic or non-traumatic iSCI with an injury onset <6 months. Intervention: Participants will be trained in one of the three groups by trained physical therapists during 10 sessions, 3x/week with an average duration of 30 minutes. Outcomes: To attain the first objective the effects will be quantified by the following main outcomes: Walking capacity (independence), walking speed, and safety. Feasibility of the systematic intervention will be evaluated using the drop-outs of therapy interventions.
