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.
Phonak Hearing Devices pass through different development and study phases. At an early stage, feasibility studies are conducted to investigate new algorithms, features and functions in an isolated manner. If the benefit is proven, their performance is then investigated regarding interdependency between all available algorithms, features and functions running in parallel in a hearing aid (pivotal/pre-validation studies) and, resulting from the pre-validation studies, they get optimized. Prior to product launch, the Phonak Hearing Systems get reviewed by a final quality control in terms of clinical trials. This is a validation study, investigating improved algorithms, features, functions and wearing comfort. This will be a clinical investigation which will be conducted mono centric at Sonova AG Headquarters based in Stäfa (Switzerland).
This study is to investigate the current use and intention to use of teledermatology in Swiss dermatology patients, dermatologists, other physicians and medical staff.
The use of quantitative, automated, infrared technology for pupillary examination has long been used in ophthalmology and anesthesiology research. Its interest in neurocritical care has progressively grown, in parallel with the advancements in device technology. In this regard, the use of the noninvasive NPi®-200 pupillometer (Neuroptics, Laguna Hills, California, USA) allows the measurement of a series of dynamic pupillary variables (including the percentage pupillary constriction, latency, constriction velocity, and dilation velocity), which can be integrated into an algorithm, to compute the Neurological Pupil index (NPi). The NPi is a proprietary scalar index with values between 0 and 5 (with a 0.1 decimal precision), an NPi value < 3 indicating an abnormal pupillary reactivity. Importantly, the NPi is not influenced by sedation-analgesia, at the doses used in neurocritical care practice, and by mild hypothermia. Preliminary single-center data recently demonstrated that abnormal NPi is associated with worse outcome in patients with traumatic and hemorrhagic ABI, and can be a useful adjunct for ICP monitoring and therapy. There is currently a great need for quantitative tools to predict early prognostication in ABI patients, and the NPi appears of potential great value. We hypothesize that: 1. Abnormal NPi (defined as NPi <3) are strongly predictive of poor GOS-E (1-4) at 6 months after the acute event. 2. NPi=0 is strongly predictive of mortality (GOS 1). 3. Abnormal NPi is predictive of a higher ICP 20 index (number of end-hourly measures of ICP >20 mm Hg divided by the total number of measurements, multiplied by 100) and a greater burden of interventions needed to control ICP (measured by the Therapy Intensity Level scale for ICP management, Therapy Intensity Level (TIL) 4). Methods This international multicentre prospective observational study aims to recruit >400 patients admitted to intensive care units. Duration of the study 18 months, including 12-month of recruitment based on 60 patients/centre plus 6 months GOS-E follow-up.
This randomised double blinded clinical trial has the aim to assess the effect of ubiquinone (Coenzyme Q10) on early wound healing following gingival recession coverage. Coenzyme Q10 (CoQ10) is a critical intermediate of the mitochondrial electron transport chain for the synthesis of adenosine triphosphate. The biological importance of CoQ10 is related to antioxidant activity, which can scavenge free radicals as well as restore the antioxidant defence system. Both in vitro and animal studies have suggested that CoQ10 acts as anti-inflammatory agent reducing the inflammatory response by inhibiting the translocation of nuclear factor kappa beta into the nucleus. Gingival recessions particularly in the esthetic area have become a common indication for treatment. The use of subepithelial palatal connective tissue graft (SCTG) in conjunction with either a coronally advanced flap (CAF) or a coronally advanced tunnel are well established techniques for both the treatment of single and multiple gingival recessions. Interestingly, despite the fact that CoQ10 is widely investigated, virtually no information exists on its effects upon early wound healing of oral tissues. Therefore, the aim of this study is to investigate the effect of CoQ10 on wound healing after gingival recession surgery.
The study is to investigate the antibody response in the blood and saliva of people with a known COVID-19 infection in the canton of Baselland.
Investigators suggest that in lean subjects cortisol increases in response to overfeeding and that this increase is blunted in obese subjects. A group of 18 male healthy lean subjects and another group of 18 male healthy obese subjects will undergo a high-calorie meal test. Prior to the meal intake, an indirect calorimetry, bioelectrical impedance, heart rate variability, a fasting blood sample and a perceived stress questionnaire will be assessed. After intake of the study meal, blood tests will be performed in order to measure the secretion of cortisol, glucose and lipid metabolism and inflammatory markers. Indirect calorimetry will be assessed again 60 and 180 minutes after the meal intake.
Burns treatment and management has evolved since the 90s, particularly for massive burns (≥ 50% of total body surface area (TBSA)). This study aims at analyzing the impact of the management changes on the length of intensive care unit (ICU) stay, the take of skin grafts and the mortality.
Night-time micturition, called nocturia, is a very common problem that unfavourably influences sleep- and life-qualities. The International Continence Society (ICS) defines nocturia as micturition once or several times during the night. Nocturia is one of the cardinal symptoms of overactive bladder (OAB). Persons with nocturia have the intention to continue sleep after going to the toilet which does not succeed to the same extent, depending on age. The natural occurrence of the plant, Bryophyllum pinnatum (BP) which is used in this observational study origins from Madagascar as well as in tropical Africa, South America and Asia. In the folk medicine of these countries BP is widely used. BP has a calming, spasmolytic, anti-inflammatory, pain-relieving, diuretic and cytotoxic effects. According to previous preclinical and clinical studies the inhibiting effect of BP on overactive bladder was proven. The pharmacological effect of this plant on uterine smooth muscle cells, on spontaneous and oxytocin-stimulated contractions, and on detrusor muscle cells in an in-vitro model of the pig's bladder was shown. Smooth muscle relaxation is not only required for preventing premature labour but also for symptom's relief of overactive bladder (OAB). The flavonoid, aglycons and bufadienolides, are components of the pressed juice of the BP leaves that have comparable effects to the standard drug oxybutynin on vesical smooth muscle cells. Since many year BP is used in obstetrics not only as tocolytics but also as a sedative and sleeping pill. There are known only few adverse events, such as skin irritation by intravenous application. The interest in phytotherapeutical drugs for treatment the chronic diseases is very high and Bryophyllum is also frequently used in Switzerland for hyperactive conditions. In Switzerland, following the vote on complementary medicine on 17.05.2009, alternative treatments will be covered by basic health insurance. Definitive inclusion in the catalogue of benefits will be granted if effectiveness, safety and cost-effectiveness can be demonstrated. The potential and side-effect profile of BP, as well as the social interest in research into alternative methods is the background to the implementation of this observational study.
It is studied whether multi-parametric biomarkers such as speed-of-sound imaging or others, applied during breast ultrasound (BUS) imaging allows to classify lesions according to its malignancy. The standard reference intervention is BUS guided biopsy or the consensus of the board of experts judging the BUS imaging results if no biopsy is done.
Traumatic anterior shoulder instability is a common injury for the contact athlete, with high rates of recurrence in some athletic populations. The specific indication for the Latarjet procedure differs amongst surgeons, however it is generally accepted that it is indicated in patients with anterior glenohumeral instability that are unlikely to have a successful outcome from either an arthroscopic or open anatomical Bankart repair. Overall the rate of reoperation following a Latarjet is around 5-7%. Infection, hematoma as well as screw removal and glenoid bony rim fractures are the most common indications for reoperation. The rate of instability after a Latarjet is low, with 1.7%-5.0% rate of dislocation. However, in terms of rehabilitation, there are only a few studies and evidence of best practices. A recent review of the literature has highlighted four studies, comparing different rehabilitation protocols, which include different immobilization periods ranging from 0 to 3 weeks, and different types of mobilization (under physiotherapist supervision or not, with machine or not). They found a similar rate of recurrent dislocation between the different protocols. But early passive motion enables to improve the range of motion during first 3-6 months, with similar results at one year. One main aspect which the surgeon can influence is immobilization time. In all above-mentioned studies, patients had to wear a sling for at least 3 weeks, even in the early mobilization groups. Short protocols with encouraging results have been recently emphasized by in other fields of shoulder surgery. The investigators would like to determine if the absence of postoperative immobilization could lead to improved function and better range of motion. To the investigators best knowledge, no study has sought to compare the usefulness of sling wearing after Latarjet procedure. Avoiding the sling could simplify rehabilitation and should provide a return to normal function faster.
