There are about 25560 clinical studies being (or have been) conducted in Germany. 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 primary purpose of this study is to estimate the percentage of participants in the population considered clinically as not having pulmonary hypertension (PH) that are positive for PH biomarker (micro ribonucleic acid [RNA]); estimate the percentage of participants in the population considered clinically as not having PH that are positive for PH by cardiac magnetic resonance imaging (MRI) and compare results of the MRI to the biomarker results; to determine the performance of the biomarker signatures identified in the CIPHER (NAPUH0001) study in terms of sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV), in a population considered clinically as not having PH.
A validated mobile Allergen exposure chamber (AEC) is used to expose qualified study participants suffering from house dust mite (HDM) induced allergic rhinoconjunctivitis. A maximum of four individuals are exposed at a time under standardized conditions with a mixture of allergens from Dermatophagoides pteronyssinus and Dermatophagoides farinae (each 50%, faeces and body allergens; doses of 250 μg/m3 air; 21°C, and 55% relative air moisture). After the first exposure, a dietary supplement lozenge, containing beta-lactoglobulin (BLG), iron, retinoic acid, zinc and polyphenols, is taken twice daily for a period of 12 weeks, followed by the second exposure. A minimum of thirty persons are challenged with HDM allergen. After entering the chamber there is an acclimatization phase of 20 minutes with no exposure. Exposure time starts after acclimatization in the chamber and is 120 minutes at each visit. Objective parameters are recorded every 30 minutes, and subjective parameters are recorded every 10 minutes over a period of 120 minutes. During the exposure a plateau (steady-state) of total nasal symptom score with a difference from baseline is measured in all participants for each of the two exposures with HDM.
The study aims to compare the conventional pull-percutaneous endoscopic gastrostomy (pull-PEG) with a pull-PEG with gastropexy suture regarding the peristomal infection rate.
Malnutrition and loss of muscle mass frequently occur in patients undergoing chemotherapy and can negatively effect therapy outcome. Especially patients with cancer of the gastrointestinal tract are often affected by malnutrition. Therefore, this study aims to examine changes in nutritional status of patients with cancer of the gastrointestinal tract during chemotherapy. Findings of this study will help to improve nutritional treatment of patients undergoing chemotherapy.
To evaluate the efficacy and safety of INCB054707 in participants with hidradenitis suppurativa over a 16-week placebo-controlled treatment period followed by a 36-week open-label extension period. All eligible participants will be invited to continue treatment for an additional 48-week Long-term extension period (also open label).
The purpose of this study is the investigation of biomechanical properties of the cornea using computer-aided data analysis. Currently, it is known that keratoconus and glaucoma are ocular disease that are associated with biomechanical alterations of the cornea. Corneal ectasia, especially keratoconus, is a corneal disease that leads to an irreversible loss of visual acuity while the cornea becomes steeper, thinner and irregular. For these patients, surgical intervention (e.g. corneal cross-linking) is performed, in case of disease progression. In glaucoma, the information about corneal alterations serves in two ways, first, correct measurement of intra ocular pressure (IOP); second, early diagnosis of suspects before visual field defects are detectable. Especially, the Corvis ST is an air-puff tonometer that measures intraocular pressure, corneal thickness (CCT) as well as dynamic corneal response (DCR) parameters. Most of the DCR parameters are affected by IOP and CCT: Therefore, algorithm are needed to determine parameters without impact of IOP and CCT that are describe the biomechanical properties of the cornea.
The DIPS (Diagnostisches Interview bei psychischen Störungen) is a structured interview to assess a variety of the most frequent psychological disorders. Its reliability and validity has been studied in clinical samples. Since structured interviews are also used in non-clinical samples like epidemiological research the investigators would like to conduct a study in a community sample to test the interview's reliability, validity and acceptance.
In healthy people, but especially in people with diabetes, dry and cracked skin areas on the feet can occur. It is believed that the appearance of dry skin results from a deterioration in the barrier function due to (neuro-) physiological or neuropathic changes in the skin. The standard treatment for skin dryness mainly consists of appropriate care with moisturizing cleaning and care products to protect and restore the barrier function of the skin. Care products containing urea are often used here because urea reduces the feeling of dry and cracked skin due to its moisturizing, keratoplastic, bacteriostatic, antifungal, itch-relieving and proteolytic properties. However, urea-containing preparations can cause painful skin irritation and burning pain on cracked, injured or extremely inflamed skin. Comparable care effects with better tolerance were postulated for care creams enriched with L-arginine. Therefore, a newly developed cream containing 4% L-arginine for the care of dry and cracked skin should be tested in comparison to a conventional care cream containing 5% urea.
Malnutrition and muscle wasting are common consequences of life-threatening, chronic diseases of the gastrointestinal tract. Such diseases include liver cirrhosis, chronic pancreatitis and short bowel syndrome. Malnutrition and muscle wasting increase the risk of complications, reduce the life expectancy and impair the quality of life. The development of malnutrition and muscle wasting is different, as is the diagnosis and nutritional treatment. There are also different mechanisms of origin for the underlying diseases. The aim of the study is to compare data related to nutrition and physical condition of patients with liver cirrhosis, chronic pancreatitis and short bowel syndrome. Malnutrition and muscle wasting within the specific diseases will be characterized and possible correlations will be identified. For this, malnourished and non-malnourished patients of the different diseases are compared with controls patients with non-specific complaints of the gastrointestinal tract as well as with healthy study participants. Data on food intake, physical activity, body composition and body measurements as well as muscle strength and muscle function are recorded. Blood values as well as transport and barrier properties of the intestine will also be examined.
In this study, the main goal is to implement and evaluate a novel, evidence-based psycho-educative program for children in oncological care. Patients are provided with booklets tailored to each specific stage of their treatment. Among other factors, children's emotional well-being is evaluated as well as feasibility. The study is carried out at multiple sites across Austria, Germany and Italy/South Tirol.
