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 study aims to summarize patients with mastocytosis and hypertryptasämia (without underlying mastocytosis or no bone marrow biopsy) in relation to demographic information, clinical progress and treatment courses. Biologic samples are collected from available routine diagnostics (serum, skin tissue, gut mucosa, bone marrow, and others) for further use in experimental research.
Stroke is the most common neurological disease in the elderly population and accounts for substantial disability and health care costs. Disability is largely driven by mobility deficits caused by impaired gait. Effective treatments are available to restore lower limb function and improve gait, but response to treatment varies greatly from patient to patient and often shows only small effect sizes. Addressing this heterogeneity requires personalization, a concept referred to precision neurorehabilitation. StimuLOOP.S intends to foster structured and reproducible methods for precision neurorehabilitation of gait in stroke. The investigator will carry out a proof-of-concept study to investigate the integration of two personalized methods for each patient. Two innovative technologies are applied in concert to enhance the recovery of lower limb function. 1. Hyper-personalized feedback (HPF): For lower limb motor rehabilitation, the investigator will employ real-time continuous feedback for movement aspects that are specific to each participant's motor deficit. The feedback will be adapted and tailored to each participant. This results in a two-step personalization; in the first step, the investigator will choose what movement aspect is therapeutically targeted, and in the second step, the investigator will define the feedback presented to the participant. 2. Targeted auditory stimulation during sleep (TASS):The investigator aim to reactivate rehabilitation- related memories through the presentation of auditory stimuli during sleep with the goal of promoting motor memory consolidation into stable motor commands. The HPF intervention is expected to induce rapid adaptations, which however do not persist over multiple days. To counter this, the investigator will leverage memory reactivation during sleep to enhance the consolidation of the movement patterns that are learned during HPF. The investigator expect that these interventions will lead to greater gains in functional walking ability. Beyond demonstrating a proof-of-concept for novel methods of precision neurorehabilitation, positive results of this project may have implications for neurorehabilitation treatment in general by providing first insights into the benefits and interplay of HPF and TASS.
A pilot study is being conducted to compare a new plant-based protein drink to commercially available animal-based protein drinks. The goal is to assess if the plant-based drink delivers amino acids to the bloodstream as effectively as the animal-based drinks, potentially offering a viable option for those on plant-based diets. The study will involve approximately 12 healthy adults aged 18-40. Each participant will try all three drinks (the new plant-based drink, a commercial animal-based drink, and another animal-based recipe) on separate days in a randomized order. Before and after (30, 60, and 90 minutes) consuming each drink, a small blood sample will be drawn to measure amino acid levels (leucine). By comparing the results, the investigators hope to determine if the plant-based drink can match the effectiveness of animal-based protein drinks in delivering essential nutrients. This research could contribute to the development of sustainable and nutritious plant-based protein alternatives.
The aim of this project is to monitor, guide and document vaccination, vaccine responses, persistence of protection, vaccine efficacy and safety in immune compromised patients at various moment of their disease: right after the diagnosis, before the introduction of the immunosuppressive treatment, once the individual is under immunosuppressive treatment, or once immunosuppression is over.
One of the main side effects of radiation therapy to the head and neck region is altered taste sensation. This causes significant morbidity and has profound effects on the quality of life (QoL) of patients. While radiation-associated toxicities like xerostomia and dysphagia are part of large investigations, data on taste impairment is sparse. The TASTE study sets out to further our understanding of this common side effect with the goal to prevent radiation-associated taste impairment in future patients. In this prospective, observational multicenter study 150 head and neck cancer patients undergoing radiation therapy will be recruited. Participants will undergo repetitive (semi-) objective and subjective assessment of their taste, smell and salivary function at specific time points before, during and after radiotherapy. Primary endpoint will be patient-reported taste impairment 12 months post radiation therapy using a standardized quality of life questionnaire (MDASI-HN). Secondary endpoints will include taste impairment measured using taste strips at 12 months and 2 years post radiation therapy. Differences between subgroups (radiation side, chemotherapy, etc.) and changes over time will be assessed while adjusting for confounding factors (e.g. age, sex, smoking history). Based on the aquired data, a normal tissue complication probability model for late radiation-associated taste impairment will be develeoped.
Peripheral regional anesthesia is the current gold standard of opioid-sparing perioperative analgesia, especially in shoulder, upper limb, and leg surgery. Axillary brachial plexus nerve block is one possible block for upper limb surgery. Loss and return of sensation require time and loss of sensation is supposed to spread from the proximal part to the distal part of the upper limb. Interestingly, until now there is no study about the return of sensation related to the anatomic region. The investigators hypothesize that the loss and return of sensation after axillary brachial plexus nerve block will first occur in the proximal part of the upper limb and last in the distal part.
The development of neuropathic pain is one of the most debilitating sequels after a spinal cord injury (SCI). The overall aim of this study is to investigate potential underlying pathophysiological mechanisms of neuropathic pain after SCI. The functionality of the nociceptive pathway in humans as well as its plastic changes following SCI will be inferred with sophisticated sensory and pain phenotyping using quantitative sensory testing (i.e., psychophysical measures), objective neurophysiological measures of pain processing and the recording of pain-related autonomic responses (i.e., galvanic skin response, cardiovascular measures and pupil dilation). In addition, the interplay between the somatosensory and autonomic nervous system and its association with the development and maintenance of neuropathic pain after SCI will be investigated.
The goal of this observational study is to learn about quality of life, stress and caregiver burden in patients with stroke and their caregivers. The main question is: • to discover the factors associated with quality of life and stress in patient-caregiver dyads. Participants will be asked to fill out questionnaires and agree to provide a hair sample (in order to measure stress hormones in hair) and consent to use of their routine clinical and laboratory data. Researchers will compare a group of participants without stroke to establish a comparable baseline.
RED4MS is a clinical trial to assess the safety, tolerability and efficacy of autologous peptide coupled red blood cells (CLS12311) in patients with relapsing remitting multiple sclerosis (RRMS). CLS12311 consists of autologous red blood cells (RBCs) chemically coupled with antigenic peptides and aims to treat RRMS by induction of antigen-specific immune tolerance.
The permanent bedding of critically ill neonates and infants in the pediatric intensive care unit (PICU) for an extended amount of time can result in the development of pressure injuries (PI). PIs can form due to high and permanent local interface pressure induced by contact with bed surfaces or other medical devices. The currently used state-of-the-art support systems consist of conventional foam mattresses. In this study, the investigators explore the effect of a newly developed air mattress with regard to contact are and reduction in the average interface pressure in infants assigned to the pediatric intensive care unit of the childrens hospital in Zurich.
