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 purpose of this study is to determine whether extracorporeal circulation during cardiac surgery has an influence on ADAMTS13-Activity.
The current standard for biopsy-based diagnoses of dysfunction of kidney transplants is the Banff Classification which represents arbitrary international consensus. Recent data-driven approaches using molecular and conventional technologies indicate that mere consensus produces frequently incorrect diagnoses with potential harm to patients due to inappropriate treatment. To address this unmet need and improve diagnostics in the area of organ transplantation, the Alberta Transplant Applied Genomics Centre (ATAGC) has developed a new diagnostic system that combines the molecular and histopathological features of transplant biopsies, plus clinical and laboratory parameters, to create the first Integrated Diagnostic System. The present study will validate and refine this system in 500 prospectively unselected biopsies for clinical indications from American, Canadian and European centres in addition to 300 biopsies already collected. Due to a considerable interest and support from participating Centers, the study is further extended to 1500 prospective biopsies. Thus this is the extension of the INTERCOM study (INTERCOMEX). In addition to demonstrating the feasibility and value of this System in routine patient care and clinical trials, the study will develop and optimize a transparent and user-friendly reporting format to communicate this information to clinicians and obtain detailed feedback on how this system can best improve patient care.
Electrical Impedance Tomography (EIT)is a technique based on the injection of small currents and voltage measurements using electrodes on the skin surface generating cross-sectional images representing impedance change in a slice of the thorax. It is a radiation free, non-invasive and portable lung imaging technique. Impedance changes in lung ventilation are investigated in mechanically ventilated patients who routinely undergo bronchoscopy in intensive care medicine. Bronchoscopy is performed to suction secretions as well as to analyze the secretions to recognize inflammations and diseases. It is an essential intervention which causes changes in ventilation which remain for 1-2 hours. It is not completely investigated why these changes in ventilation remain for so long time and how they are distributed regionally. Therefore the purpose of this study is to investigate the change in pulmonary regional ventilation in patients who routinely undergo bronchoscopy to possibly generate ideas how to optimize the ventilation after bronchoscopy to optimize the patient´s treatment.
Cardiac output can be monitored using different invasive devices. Nexfin HD is a new, noninvasive device that uses model flow technology to measure stroke volume and thus computes cardiac output (CO). To evaluate this new device the investigators compared esophageal doppler CO to Nexfin HD CO in patients scheduled for elective abdominal surgery.
Neuropeptide Y (NPY) may play a major role in the pathophysiology of aneurysmal subarachnoid hemorrhage (aSAH). To investigate the correlation of NPY in cerebrospinal fluid (CSF) and blood (serum) and the neurological outcome in the acute stage of aSAH.
The purpose of this study is to determine whether levels of circulating endothelial progenitor cells (cEPC) are increased in the acute phase of ischemic stroke.
The aim of the study is to investigate the epidemiology, natural history and treatment outcomes of acute hepatitis C (HCV) infection. Given the current pattern of case reporting, the cohort will be largely made up of human immunodeficiency virus (HIV)-positive patients, but HIV-negative patients with acute hepatitis C (AHC) will also be enrolled to enable comparisons to be made as appropriate and possible.
The purpose of the Multi-National Gilenya Pregnancy Exposure Registry in Multiple Sclerosis (MS) is to continuously monitor, evaluate, and assess for major and minor teratogenic effects in the offspring of women exposed to fingolimod before (up to 8 weeks before last menstrual period (LMP)) and during pregnancy in routine clinical practice. The overall aim is to collect and evaluate data on maternal, fetal, and infant outcomes and compare it with reference populations.
The purpose of the study is to describe and characterize CML in a large pediatric cohort of patients.
In ventilated patients with acute respiratory failure endotracheal suctioning may lead to alveolar derecruitment, which can be monitored by means of functional residual capacity (FRC) measurements. Regional distribution of ventilation can be followed at bedside using electrical impedance tomography. The investigators hypothesize that a FRC guided recruitment strategy, aimed at restoring a baseline FRC value after open endotracheal suctioning, improves oxygenation and regional distribution of ventilation. In addition the investigators research the impact of such a strategy on the inflammatory response to mechanical ventilation.
