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.
Chronic wounds are common and carry out an important and often neglected burden not only to the individual, the family but also to the society as a whole. The therapeutic approach to the management of chronic wounds include wound bed preparation or wound dressing management. Wound bed preparation is a concept emphasizing a holistic and systematic approach to evaluate and remove barriers to the healing process to allow the wound healing process to progress normally. Debridement is an integrated part of wound bed preparation, achieving certain goals and, thus, creating a healthy wound bed, margins and peri-wound skin with the objective to promote and accelerate healing. Debridement is defined as the removal of foreign material and necrotic tissue from a wound and it can also help to stimulate wound healing. However, not all methods of debridement are the same. Each method has advantages and disadvantages that must be clearly understood. In the present clinical practice, there are several methods of wound debridement: autolytic, enzymatic, mechanical, surgical (sharp) and biologic. The most common method is the mechanical debridement. Currently a micro-water jet technique was introduced into clinical practice. The micro-water jet technique Debritom+ is an effective alternative to traditional instrument interventions performed with the scalpel and/or curette. A sterile liquid is expelled from a nozzle at a selected intensity and accurately sprayed onto the wound surface. The desired effect is the generation of targeted micro-bleedings to stimulate regeneration and healing processes while preserving the underlying healthy tissue. Today, there is no clinical evidence quantitatively comparing one debridement method over the other. Therefore the invesitgators propose a pilot study to measure the extent of tissue loss after debridement using Debritom+ micro-water jet technology versus traditional instrument debridement procedure using scalpel and curette.
The "BPET prototype" is a small aperture PET scanner. The BPET prototype will be used with patients, which have just finished their regularly scheduled PET examination on a clinical whole body PET system. The radioactive tracer used for this procedure will still be active. This remaining acitivity will be used for an image acquisition with the BPET prototype without the need for an additional radioactive tracer dose. The control intervention is be a brain PET scan as part of standard clinical routine. It will be done immediately before the scan on the BPET prototype.
Due to the growing world population, there is a need to develop viable ecological and nutritional alternatives to animal food products. However, animal products are a key dietary source of well-absorbed iron, and iron deficiency and iron deficiency anemia remain highly prevalent in high- and low-income countries. Meat and fish provide a substantial proportion of absorbed iron in the western diet by two distinct components: a) heme iron is well absorbed (20-45% fractional absorption) and is not affected by most dietary enhancers and inhibitors, which often affect non-heme iron absorption; b) peptides in muscle meat exert an enhancing effect the absorption of non-heme iron contained in other meal components. The potential of edible insects as a dietary source of well-absorbed iron has not been investigated in detail. In particular, it is unclear whether insects provide an iron moiety similar to hemoglobin which would be well absorbed and unaffected by other dietary components, and whether their presence in a test meal exerts an enhancing effect on iron bioavailability from the whole meal. Furthermore, chitin, a major component of insect biomass, is a known iron binder and is potentially responsible for a decreased iron absorption from insect-based foods. Decreasing chitin content could allow the high amounts of iron in insects to be well-absorbed, and enhance the absorption of iron from plant-based foods. To differentiate iron absorption from insect biomass from other sources, insects will be intrinsically labelled with the stable iron isotope 57Fe, while other food iron components will be labelled with the iron isotope 58Fe.The present study will provide novel data to elucidate the nutritional value as sources of dietary iron of insect species (Tenebrio molitor). Since 2017 T.molitor is recognised as an edible insect in the Swiss food legislation and commercially available (Essento Food AG, Zürich; Insekterei, GmbH, Zürich).
The purpose of this study is to evaluate whether Canakinumab has beneficial effects on patients with Type 2 diabetes mellitus and coronavirus disease 19 (COVID19).
The Investigators plan to study the innate and adaptive immune response, the inflammatory response, and associated complications such as complement activation and neurological damage in SARS-Cov-2 infected individuals. Patients with mild, moderate and severe COVID-19 disease will be enrolled.
We aim to assess the benefits and harms of higher (12 mg) vs lower doses (6 mg) of dexamethasone on patient-centered outcomes in patients with COVID-19 and severe hypoxia.
The objective of the study is to evaluate the effects a complex recovery intervention during the breaks of a repeated sprint test on exercise performance compared to placebo and control conditions. The enhanced recovery package (ERP) includes neck cooling with an iced gel pad, drinking a 6% CHO solution, mouth-rinsing with a 10% CHO, 6 mg･kg -1 caffeine solution, performing submaximal squats and hyperventilating a hyperoxic mixture; all applied in each 3-min break in-between the six 30-s sprints. This intervention will be compared to a placebo and a control condition.
In this study, we investigate the role that deep sleep plays in the prevention of posttraumatic stress disorder after someone has been exposed to a trauma by boosting deep sleep with two drug conditions compared to placebo condition. Each volunteer in the study goes through all three conditions. The quantity of intrusive memories of the trauma will be compared between the three conditions.
This study investigates under controlled conditions the variation of poorly ventilated lung units (silent spaces) in children between 1 and 6 years of age measured by electrical impedance tomography during intravenous anaesthesia in a day-hospital setting and before discharge to help further raise safety standards in paediatric anaesthesia
Background: Lateral maxillary sinus augmentation (MSA) is a predictable bone regeneration technique in case of atrophy of the posterior-upper maxilla. Aimed at obtaining quantity and quality of bone suitable for receiving osseointegrated implants, its success is largely due to the skill of the surgeon, but also to the characteristics of the biomaterial used. Methods: Twenty-four patients needing MSA were included in the study. The patients were randomly allocated to 3 different groups: Anorganic Bovine Bone Mineral (ABBM) as control, Tricalcium Phosphate (TCP) with or without hyaluronic acid (HA) as test groups. Nine months after MSA bone biopsies were harvested for the histomorphometric analysis. Secondary outcomes were mean bone gain, intraoperative and post-operative complications, implant insertion torque, implant failure and patient related outcome measures (PROMs).
