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 aim of this study is to improve treatment of Moderate Aplastic Anemia (MAA) by evaluating the safety and efficiency of Eltrombopag as a new treatment option in patients with therapy requiring MAA.
The purpose of this study is to estimate the proportion of participants fulfilling criteria for symptomatic remission following a transition to 12 months treatment with flexible-dose paliperidone palmitate 3 month formulation (PP3M) in participants with schizophrenia previously adequately treated with paliperidone palmitate 1 month formulation (PP1M) for at least 4 months.
Treatment of complex unruptured intracranial aneurysms (UIA) remains challenging to date. Therefore, advanced techniques are required to achieve an optimal result in treating these patients safely. In this study, the safety and efficacy of rapid ventricular pacing (RVP) to facilitate microsurgical clip-reconstruction has been studied prospectively in a joined neurosurgical, anesthesiological and cardiological study.
ProtoChoice-P is a prospective multicenter trial to evaluate proton therapy in patients suffering from prostate cancer. Primary aim of the study is a decrease of moderate or severe genito-urinary or intestinal side effects (Common Terminology Criteria for Adverse Events (CTCAE) 4.0 grade 2 or higher) by the use of proton therapy. Secondary endpoints contain assessment of quality of life, biochemical recurrence and recurrence free survival as well as overall survival and economic comparison between photon and proton therapy.
The Cognition Intervention Study Dortmund (CogniDo) and the Cognition Intervention Study Dortmund PLUS (CogniDo PLUS) investigated the short-term effects of having school lunch versus skipping it on children's basal (CogniDo) and executive (CogniDo PLUS) cognitive functions in the afternoon. The The Cognition Intervention Study Dortmund Continued (Coco) connected this two previous studies and investigates the effect of having school lunch versus skipping it on children's basal and executive cognitive functions later in the afternoon. The present study the Cognition Intervention Study Dortmund- Glycemic Index (CogniDo GI) examines the influence of the gylcemic index of lunch on cognitive performance of school children in the afternoon.
Adenomas and hyperplastic polyps are polypoid lesions that can occur in any part of the colon. Currently all polyps should be resected endoscopically, however adenomas have the potential to develop into colorectal cancer whereas hyperplastic polyps do not. This approach enables the lesions to be evaluated under the microscope. Currently only the pathological diagnosis can distinguish exactly between adenomas and hyperplastic polyps. Acetic acid (AA) chromoendoscopy is already widely used in order to improve optical determination of mucosal lesions in the upper gastrointestinal tract. In the colon only few studies investigated the impact of AA in differentiating normal mucosa from suspicious mucosa. The aim of the present study is to evaluate the value of spraying acetic acid as an adjunct for optical characterization of colon polyps. Using AA may be beneficial for determining optical diagnoses of colon polyps during real time colonoscopy. This is a single-arm proof of principle study. If colon polyps are found during colonoscopy a 1.5 percent AA solution will be used for chromoendoscopy. Endoscopists are encouraged to use the Narrow Band Imaging (NBI) function of the endoscope prior to the use of AA. After AA is sprayed endoscopists will diagnose the polyp optically. Endoscopists have to predict adenomatous or non-adenomatous histology based upon optical features of the polyp. All polyps will be resected endoscopically so that histopathological diagnoses can be determined. After completing the trial the investigators aim to compare optical and histopathological-based diagnoses of polyps. Histopathological diagnoses will serve as the gold standard. Based upon this information the accuracy of the optical diagnoses will be calculated. The investigators hypothesis is, that optical-based diagnosis using NBI and AA will be accurate in > 75% of all polyp cases.
The purpose of this study is to evaluate the safety and effectiveness of the Hybrid Closed Loop system (HCL) in adult and pediatric patients with type 1 diabetes in the home setting. A diverse population of patients with type 1 diabetes will be studied. The study population will have a large range for duration of diabetes and glycemic control, as measured by glycosylated hemoglobin (A1C). They will be enrolled in the study regardless of their prior diabetes regimen, including using Multiple Daily Injections (MDI), Continuous Subcutaneous Insulin Infusion (CSII) or Sensor-Augmented Pump therapy (SAP)
The main objective of the project is to bring the existing radio frequency ablation (RFA) model for liver cancer treatment (Project IMPPACT, Grant No. 223877, completed in February 2012) into clinical practice. Therefore the project will pursue the following objectives: i) to prove and refine the RFA model in a small clinical study; ii) to develop the model into a real-time patient specific RFA planning and support system for Interventional Radiologists (IR) under special consideration of their clinical workflow needs; iii) to establish a corresponding training procedure for IR's; iv) to evaluate the clinical practicality and benefit of the model for use in the routine workflow in a user survey and expert forum.
Acetate is the primary acidifying solution used in bicarbonate-based hemodialysis worldwide. It has been published in small trials or case series that the addition of acetate is associated with a rise in nitric oxide production of vascular smooth muscle cells, endothelial cells and myocardial cells as a sign of vascular dysfunction. Furthermore clinical side effects of dialysis e.g. nausea, malnutrition, intradialytic blood pressure drops, induction of proinflammatory cytokines and activation of complement and leukocytes have been described with acetate. Citrate on the other hand was associated with: Acid-base disorders (metabolic alkalosis), Disturbances of the calcium homeostasis (Hypocalcemia), but also anti-inflammatory effects. Both dialysate additives (citrate and acetate) are commercially available and are used world wide in dialysis centers. The investigators hypothesize that substitution of acetate by citrate reduces the cardiovascular risk (measured by a change in the surrogate parameter of pulse wave velocity and Augmentation index) and might improves quality of life in the participants. Furthermore the investigators speculate that citrate in the dialysis solution could reduce systemic inflammation in the participants of the study.
This monocentric, non-interventional observational registry study was designed in order to obtain data of patients with the indication for a flexible bronchoscopy to control and optimize a guideline conform therapy of these patients.
