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.
Undernutrition has a known and well recognized negative impact on reproductive hormones, and ultimately fertility. In contrast, much less is known regarding the potential effects of overnutrition on the same hormones. Epidemiological data suggest that overnutrition might have a deleterious impact as well on the fertile potential of affected women, but very little is known about the mechanisms implicated. Such knowledge may be of importance, given the increasing prevalence of overweight and obesity worldwide.
A prospective, randomized, controlled study to assess efficacy, safety, and tolerability of selective laser trabeculoplasty vs. pattern laser trabeculoplasty in patients with open-angle glaucoma.
The primary objectives of the study are to determine the incidence of serious adverse events (SAEs) in participants with relapsing forms of multiple sclerosis (MS) in routine clinical practice and to assess the overall long-term clinical effectiveness of Plegridy in participants with relapsing forms of MS in routine clinical practice. The secondary objectives of this study in this study population are to describe Plegridy prescription and utilization adherence patterns in routine clinical practice; to assess the specific long-term clinical effectiveness of Plegridy in participants with relapsing forms of MS in routine clinical practice; to monitor the safety and tolerability of Plegridy in routine clinical practice by assessing the incidence of adverse events (AEs) of flu-like symptoms (FLS), injection site reactions (ISRs), and AEs (including laboratory abnormalities) leading to treatment discontinuation; to assess the effect of FLS on participant-reported effectiveness of, and satisfaction with, prophylactic management using a FLS-Visual Analog Scale (FLS-VAS); to evaluate the change in health-related quality of life (HRQoL), FLS, FLS-VAS, healthcare resource consumption, and treatment adherence over time.
Enamel matrix proteins have been shown to play a crucial role during tooth development and its supporting tissues. This is used in periodontal surgery where regeneration of lost tissues around the teeth is intended. Emdogain, a product of Straumann Institute contains these matrix proteins and has been successfully used in regenerative periodontal surgery for more than 16 years. The treatment of gum recession is a common requirement, more and more patients are seeking treatment at the investigators' clinic due to aesthetic concern, root sensitivity and difficulties in performing adequate oral hygiene. The standard treatment comprises the transplantation of a piece of connective tissue from the palate to the denuded root surface. In many cases Emdogain is additionally applied to enhance healing. So far the effect of Emdogain on the early wound healing process after surgical root coverage has not been investigated. The purpose of the investigators' study is to compare early wound healing parameters between treatment with and without Emdogain. For this study 40 patients undergoing root coverage surgery at the investigators' department will be included. Early wound healing features between the two groups will be described and compared. Furthermore, inflammatory markers typical for early healing will be evaluated together with patients`subjective postoperative comfort. Finally, outcomes 6 months after the treatment will be assessed. The investigators' hypothesis is that Emdogain treatment enhances wound healing and decreases post-operative complication rates.
This study investigates wether patients with increased trigeminal perception threshold and low expression of TRP channels have more often nasal blockage despite functionally successful nasal surgery (TRP channel = transient receptor potential channel).
The important role played by the GI tract microflora on the metabolic health of an individual are increasingly recognized. In this respect, the initial studies of Metchinkoff that suggested a role of fermented food (specifically yoghourts ) to modulate the gut microflora have evolved into the concept of "probiotics". Probiotics are living microorganisms that bring a benefit to the host when administered in sufficient quantity (WHO/FAO, 2001). Here the investigators will study, in normal young male volunteers, the potential to modulate post-prandial metabolic and inflammatory responses by the administration of a yoghourt containing the probiotic Lactobacillus rhamnosus (LGG).
The majority of testicular cancer patients can be cured with cisplatin-based chemotherapy. Mortality has been reduced even more within the last 15 years due to the stringent application of standard chemotherapy followed by resection of residual disease. This is a positive development considering that testicular cancer usually affects young men. Active surveillance has become an acceptable and widely used strategy in stage I testicular cancer. Thus, it is important to follow these patients in a standardized way and to adhere to a rationale surveillance strategy. There is no international consensus regarding follow-up of testicular cancer patients. Stratification according to risks and patterns of relapse would allow to tailor follow-up schedules, aiming at early identification of relapse without causing unnecessary harm by using excessive radiation in these young long-term survivors. Follow-up procedures should not only aim at detecting relapse, but also long-term side effects from therapy, including hypogonadism, metabolic syndrome, cardiovascular disease and secondary malignancies. The Swiss Austrian German Testicular Cancer Cohort Study (SAG TCCS) will comprise consecutive newly diagnosed testicular cancer patients and is the first study to prospectively evaluate the initial indictor of relapse in testicular cancer patients, the frequency and pattern of relapse and document long-term toxicities of the treatment (cardiovascular, gonadal, hearing impairment, renal function and second malignancies) and psychosocial aspects. This cohort study will determine the relevance of each test performed routinely during follow-up. The collected data will have direct implications for the care of patients with testicular cancer and inform future adaptations of follow-up recommendations. The dataset will give information on baseline factors of testicular cancer patients patients, current treatment strategies in Switzerland, Austria and Germany, outcome and late sequelae.
The purpose of this study is to evaluate if the new and simplified fitting method with Cochlear Nucleus Fitting Software (a major component of a suite of tools which form the Clinical Care Innovation) provides Cochlear Implants Recipients with the same hearing outcome as the current and established clinical fitting method with Cochlear Nucleus Custom SoundTM Suite. The Clinical Care Innovation method reduces fitting to simple volume, bass and trebles adjustments, operations which are familiar to anyone who has used an audio player.
Measuring ocular motility and alignment is important for diagnosing different causes of strabismus, following patients recovering from cranial nerve palsies, preparing patients for strabismus surgery and follow-up post surgery. The current clinical gold standards for measuring ocular alignment are the Hess screen and the Harms tangent screen. These tests are accurate, but require patient cooperation, and are not objective because the patient has to indicate the position of the light he sees on the screen. Our objective is to develop an accurate and easy to use goggles system to measure ocular alignment and motility using 3D video oculography.
In obese individuals cortisol production and secretion is increased but the underlying mechanism is not known. Obesity leads to a pathological activation of the innate immune system partly driven by tissue production of IL-1β. Furthermore, IL-1β is also known to stimulate the release of adrenocorticotropin hormone (ACTH). Therefore, the investigators hypothesise that in obese individuals tissue inflammation stimulates ACTH via IL-1β, thereby explaining the observed hypercortisolism.
