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.
A methodical evaluation of novel sound changing principles in CE-labelled Sonova brand hearing instruments (e.g. Phonak hearing instruments) is intended to be conducted on hearing impaired participants. These sound changing principles are enabled by respective hearing instrument technologies and hearing instrument algorithms. The aim of the study is to investigate and asses strength and weaknesses of these novel sound changing principles in terms of hearing performance to determine their application in hearing instruments (Phase of development). Both, objective laboratory measurements as well as subjective evaluations in real life environment will be carried out. This will be a controlled, single blinded and randomised active comparator clinical evaluation which will be conducted mono centric at Sonova AG Headquarter based in Stäfa
In this retrospective study, approximately 60 patients treated with 6mm short implants (Straumann, SLA (sandblasted, large-grit, acid-etched surface), SLActive (sandblasted, large-grit, acid-etched, hydrophilic surface), 4.1 or 4.8 mm in diameter) will be followed for 4.5-18.2 years. Clinical and radiographic parameters will be assessed in a follow-up examination.
The measurement of nitric oxide lung diffusing capacity (DLNO) has been recently standardised. To date, two pulmonary function devices are commercially available and are used for the measurement of DLNO. No previous study assessed differences in gas exchange outcomes (e.g., DLNO values) between both devices. The aim of this project is to compare two commercially available devices that measure lung diffusing capacity for nitric oxide (DLNO). 1. "MasterScreenTM" (PFT Pro, Jaeger, CareFusion, Hoechberg, Germany 2. "HypAir" ("HA", Medisoft, Dinant, Belgium).
Retrospective cohort study using routinely collected annual data on lung clearance index (LCI) in combination with clinical data to predict survival in patients with Cystic Fibrosis. The primary study endpoint is the association of LCI with the compound outcome survival or lung transplantation in patients with CF.
Dyspnoea is a very common symptom in many diseases, not only cardiorespiratory, but also renal or neurological diseases. It can be defined as " difficult, laboured and uncomfortable breathing […]. It is a subjective symptom. As pain, it involves both the patient's perception of the sensation and his reaction to it ". It can occur during even moderate effort and sometimes also at rest and tends to increase as the disease causing it progresses. Dyspnoea has therefore a significant on the various aspects of the patient's daily life and those around him or her (travel, leisure, daily activities, etc.) leading to a decrease in quality of life and possibly to anxiety and/or depressive symptoms. Among a vulnerable, elderly population that benefits from home care, it affects more than 46 % of patients in north-west of Switzerland. Despite the handicap generated by daily dyspnoea, this complaint is often difficult to recognize by health professionals or family and friends, due in particular to a feeling of helplessness in the care provided. In addition, the treatment of the disease responsible for dyspnoea by the doctor does not always provide relief. In this context, it is essential that people with dyspnoea, families and friends are supported in their experiences and acquire techniques and alternatives that help them better manage dyspnoea on a daily basis. The first objective is to evaluate the feasibility of a dyspnoea support program led by a respiratory care team non-specialized in palliative care and its effect on quality of life and control of dyspnoea symptoms by patients . A second objective is to measure patient's satisfaction about the program.
In addition to intraocular pressure blood perfusion pressure in the optic nerve is an important factor determing the cause of glaucoma. Increasing evidence suggests that in glaucoma patients retinal blood may be decreased.
Single centered diary-based study to identify course and characteristics of hormone withdrawal headaches/migraines in users of combined hormonal contraceptives Objectives of the Research Project: to identify the course and characteristics of hormone withdrawal headaches/migraines in users of combined hormonal contraceptives (CHC)
Pretest and validation of the German version of the Amsterdam instrumental activities of daily living questionaire short in elderly people with normal cognition, mild cognitive impairment (MCI) or mild dementia in the German speaking part of Switzerland. The aim is to investigate the psychometric properties of the final Amsterdam instrumental activities of daily living questionaire short (A-IADL-Q-SV) German. Participants with normal cognition will be recruited in the community and participants with MCI and mild dementia in three memory clinic settings.
The aim of the study is to evaluate the effect and effectiveness of the nurse-led integrated care programme for the management of COPD (Chronic Obstructive Pulmonary Disease) exacerbations on patients' quality of life, rehospitalisation and exacerbation rate, illness-related emotional distress, selected health behaviours and cost-utility at three months. Furthermore, understanding barriers and facilitators to implementation success is of interest.
In the first retrospective part of the study the investigators will conduct a data analysis of patients having received a bovine aortic graft. The investigators will analyze charts and CT / MRI at various time intervals and identify if there are signs of inflammation. In the second prospective part the investigators will select survivors from the first part with and without inflammation signs. If they consent to participate in the study the investigators will do a blood sampling in order to perform further immunological analysis. Additionally, the investigators will examine their quality of life by QoL SF-12 questionnaire.
