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.
To evaluate and to validate accuracy, precision and trending ability of blood pressure and cardiac output measurement by applanation tonometry in cardiological patients having: - atrial fibrillation - severe impaired leftventricular function - severe aortic valve stenosis - patients having left ventricular assist device Experimental measurement: continuous blood pressure measurement and cardiac output measurement is performed by the T-Line 200 pro device (Tensys Medical Inc., San Diego, USA) Control measurement: gold-standard continuous blood pressure measurement is performed by invasive blood pressure measurement by arterial cannulation and cardiac output reference is assessed by transcardiopulmonary thermodilution
QT interval changes is measured during all phases of the operation. The protocol is focusing at intraoperative bleeding events and is also observing QT interval changes during anesthetic and operative procedures.
The key goals of EUROSCA-NHS is to determine and compare the rate of disease progression in SCA1, SCA2, SCA3 and SCA6 including determination of the order and occurrence of non-ataxia symptoms, assessment of activities of daily living (ADL) and quality of life (QoL), and identification of predictors of disease progression and survival.
It is hypothesized, that local retinoic acid (RA) homeostasis is functionally involved in the pathophysiology of depression. In a cross-sectional (and partly longitudinal) analysis, serum RA status will be assessed in healthy controls and subjects with Major Depression, Alzheimer's disease, alcoholism and in subjects with schizophrenia.
Obesity is considered to be caused by an imbalance between energy expenditure and energy intake. A major determinant of our daily energy intake is the size of the meals that we consume. It has been suggested that decisions about portion sizes are often made in advance, before a meal begins. This pre-meal planning is considered to especially depend on the estimated 'expected satiety' and 'expected satiation' of different foods. Further, also factors like weight concern and palatability of the food might have their influence on meal size selection. In general, it is not clear how these factors are integrated during pre-meal planning and which brain networks are involved in these decisions/this process. Thus, the investigators plan to study pre-meal planning in healthy, normal-weight and overweight/obese individuals with functional magnetic resonance imaging under different cognitive instructions including pleasure, expected satiety and self-control in terms of health consequences. The investigators will explore the neural networks involved in pre-meal planning and expect them to be modulated by the before mentioned factors. Further, the investigators plan to explore gender differences and expect that female subjects will select smaller portion sizes especially in the self-control condition as they are often more concerned about their weight/health. Finally, the investigators will explore differences between lean and overweight subjects to elucidate factors that might lead to increased meal sizes in overweight subjects.
The aim of this long-term observational study is the documentation of the use of PASCORBIN® 7.5 g in patients with vitamin C deficiency. Regarding the vitamin C deficiency, the investigators focus on the acquisition of data of the underlying diseases and the reduction of symptoms, that are related to oxidative stress and vitamin-C-deficiency. Next to this, exact assessment of medical tolerance and details of treatment requirements are further aims. Here the investigators take into account acute and chronic underlying medical conditions. Further health economic data are collected.
The bioresorbable polymer SYNERGY EES exhibits a favourable vascular healing profile in patients undergoing coronary intervention for de novo lesions. Specifically, the SYNERGY EES is superior to the ABSORB bioresorbable vascular scaffold in terms of antirestenotic efficacy as assessed by angiography at 6-8 months.
The purpose of the international prospective PCD Patient Registry is to systematically measure, survey and compare different aspects of PCD manifestation, course and treatment, to provide data for epidemiological research and to identify special patient groups suitable for multi-center trials. This International PCD Registry is also part of the European Reference Network ERN-LUNG. We follow the recommendations of the EU Expert Committee on Rare Diseases (EUCERD), which recommend an international interoperability of registries and databases to pool and exchange knowledge and data on rare diseases.
Deep Phenotyping of adult asthma patients: - severity from mild to severe - both atopic and non-atopic - both childhood and adult onset - both smokers and non-smokers - corresponding pediatric cohort (Pediatric Arm of DZL All Age Asthma Cohort) with equivalent SOPs regarding collection of biomaterial and clinical data incl. lung function, further processing of biomaterial and further analyses
Magnetic Resonance Imaging of the heart at rest and stress conditions relative to the cardiopulmonary exercise capacity in young adults after neonatal surgery for transposition of the great arteries.
