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 determine whether a prewarming period of at least 30 minutes during induction of general and combined epidural anesthesia reduces the core temperature drop normally occuring in patients undergoing cyto-reductive and major abdominal surgery. In addition the effect of prewarming on intra and postoperative body core temperature will be evaluated.
Observational prospective multicenter study to investigate efficacy and safety of endoscopic full thickness resection in the lower GI tract using a novel over-the-scope full thickness resection device.
This is a prospective, non-randomised, non-blinded, single center study of children and adolescents with multiple sclerosis and clinically isolated syndrome to detect differences or early changes in diffusion-weighted imaging (DTI) by magnetic resonance imaging (MRI).
The event-related potentials may be different in patients with Takotsubo cardiomyopathy than in patients without Takotsubo.
This study is a prospective, randomized, monocentre, controlled explorative study in the parallel-group design to determine the pain relief after RT of patients with spinal bone metastases. Thereby two different techniques were evaluated: single fraction IMRT with 1 x 24 Gy versus fractionated RT with 10 x 3 Gy. Prior to their enrolment into the study, the patients will undergo a staging of the vertebral column in connection with their radiation-planning computed tomography (CT) and MRI to measure the myelon dimension. After the baseline results have been recorded, the patients will be randomized into one of the two groups: single-fraction IMRT 1 x 24 Gy (n = 30) or fractionated RT 10 x 3 Gy (n = 30). The target parameters will be measured and recorded at baseline, at the end of RT (t1) and twelve weeks (t2) and six months following the end of the irradiation period (t3).
The primary aim of the study is to investigate new cardiac biomarkers and algorithms to diagnose acute coronary syndrome in patients with suspected acute myocardial infarction.
Adenomatous lesions of the colon are premalignant lesions which have the potential to develop cancer. Therefore adenomas should be resected endoscopically (endo- mucosa resection, EMR). EMR is conducted after submucosal injection of saline which allows to lift the desired lesion prior to resection. In some cases EMR is complicated due to incomplete or failed lifting after the injection of saline. This so- called "non- lifting" sign is a predictor for malignancy of the lesion. Difficult- to- lift polyps are also difficult- to- resect. A higher proportion of these lesions fail to be resected completely using the EMR technique. Alternatively, an over- the- scope full- thickness resection device (FTRD) can be used in order to resect colonic lesions. The FTRD technique has been described elsewhere (Schmidt et al. Gastroenterology 2014; 147: 740-742.e2). No comparative data exists until now on the performance of FTRD resection compared to standard EMR resection of difficult- to- resect colon adenomas. In this study the investigators aim to compare the success of FTRD versus EMR of difficult- to- resect adenomatous lesions (≤ 20 mm).
Drug metabolism in the liver is subject to large fluctuations (differences between women and men, people of different ethnic backgrounds, children and adults). These large differences are responsible for very different drug effects and side-effects (and especially liver damage caused by drugs) between individuals. Recent scientific findings suggest that blood derived cells can be used to model individual effects of drugs on the liver reflect inter-individual differences. Since liver damage caused by drugs is a diagnosis of exclusion, the aforementioned cells can be used to identify patients that show higher sensitivity to hepatotoxic side-effects and - in case several drugs are involved - identify the causal agent or possible interactions.
Patients with locally advanced suqamous cell carcinoma of the head and neck region receive a hypoxia scan either by magnetic resonance tomography, computed tomography or fluoromisonidazole (FMISO)-PET-CT. Patients presenting with hypoxia are randomized into standard therapy consisting of intensity modulated radiotherapy (IMRT) with 70 Gy plus either 5-fluorouracil/mitomycin C or cisplatinum (Arm A) or a dose escalation of 10% (77Gy) to the hypoxic volume applied via simultaneous integrated boost in addition to the standard treatment (Arm B).
The purpose of this study is to shed light on the basic neurobiological mechanisms which underlie social information processing in healthy men. More specifically, we intend to examine whether a person's social competence level is related to the patterns of neural activity and his visual search strategies during evaluation of social scenes. Furthermore, it will be assessed whether an oxytocin-driven increase in activity in brain areas relevant to the task will facilitate social information processing and thus enhance task performance. Additionally it will be examined whether oxytocin can facilitate response inhibition in an emotional context.
