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 the study is to establish tDCS as a prognostic tool to predict VNS therapy outcome among patients with pharmacoresistant epilepsy.
Experimental data suggest that angiotensin II-antagonists reduce the atrial expression of prothrombotic adhesion molecules and oxidative stress parameters. The present study is designed to investigate the effects on angiotensin II-antagonist irbesartan to reduce the amounts of circulating oxidative stress markers and adhesion molecules in patients with persistent atrial fibrillation.
The objective of this study is to compare radiation dose of a standard spiral scan with the a new sequential scan protocol. We hypothesize that the sequential scan protocol is associated with a reduction in dose estimates of at least 20%, while the diagnostic image quality is not inferior. Secondary endpoints of the study include quantitative image quality parameters, diagnostic accuracy for spiral versus sequential studies compared to invasive angiography in patients who underwent subsequent invasive coronary angiography.
The objective of this study is to compare radiation dose of a 100kV scan protocol to the standard 120kV scan protocol. We hypothesize that the 100kV scan protocol is associated with a reduction in dose estimates of at least 20%, while the diagnostic image quality is not inferior. Secondary endpoints of the study include quantitative image quality parameters, diagnostic accuracy for 120 vs.100kV studies compared to invasive angiography in patients who underwent subsequent invasive coronary angiography
We conduct a randomized study comparing the safety and effectiveness of two interventional ablation techniques for treatment of paroxysmal atrial fibrillation: the segmental pulmonary vein ablation approach, (1) with empiric isolation of all pulmonary veins or (2) Segmental Isolation of the arrhythmogenic pulmonary vein(s)
Study Objectives: To collect and describe demographics, disease-management, and treatment outcomes of Myelodysplastic Syndromes (MDS) patients who are newly diagnosed and classified according to the World Health Organization (WHO) criteria. To perform observational studies concerning relevant scientific research questions in MDS using clinical data and biological samples, and to present relevant research outcomes in the fields of diagnosis and prognostication, health related quality of life issues, health economics, and risk stratification for newly developed classes of drugs. To disseminate results of the studies to all stakeholders involved.
The purpose of the study is to evaluate the quality of care on a 16 bed stroke unit by using a new developed clinical pathway.
1. Scientific background In patients with multiple myeloma high-dose chemotherapy followed by autologous stemcell transplantation is preferred to conventional therapy, since the superiority in respect to complete remission, complete remission duration, event-free survival and overall survival has been proven within well controlled clinical trials (Fassas et al., 2002; Goldschmidt et al., 2003). Nausea and vomiting are well known and the most distressing side-effects of a high dose chemotherapy regimen. The administration of selective 5-HT3-receptor antagonists (5-HT3 RAs) in combination with a corticosteroid (= antiemetic standard therapy) is effective for the prevention of those adverse effects in 70 to 80 % of patients. However, 25 to 40 % of the patients still suffer from vomiting and nausea in the delayed phase of the chemotherapy. Superior protection could be achieved with the addition of Aprepitant (EMEND®) to the antiemetic standard therapy in acute and delayed phases of highly emetogenic chemotherapies. The enhanced antiemetic protection can be maintained over multiple chemotherapy-cycles to an extent superior to that of standard therapy alone (de Wit et al., 2003). Furthermore addition of Aprepitant (EMEND®) to standard therapy was generally well tolerated and the impact of chemotherapy-induced nausea and vomiting (CINV) on daily life was significantly reduced (Hesketh et al., 2003; Dando & Perry, 2004). 2. Trial Rationale Aprepitant (EMEND®) is a selective high-affinity receptor antagonist of human substance P/neurokinin-1 (NK1) and has been shown to inhibit emesis induced by cytotoxic chemotherapeutic agents and augments the antiemetic activity of 5-HT3 RAs (e.g. Granisetron, Ondansetron) and corticosteroids (e.g. Dexamethasone). Thus Aprepitant (EMEND®) in addition to antiemetic standard therapy has been shown to possess powerful superior protection and has been reported in several clinical trials to significantly improve both acute and delayed CINV. The aim of this study is to evaluate, during and up to 7 days after high-dose chemotherapy with Melphalan (moderate emetogenic drug) followed by autologous peripheral blood stemcell transplantation, an antiemetic treatment regimen in respect to efficacy and safety in patients with multiple myeloma. To the best of our knowledge effects of Aprepitant on Melphalan induced CINV have never been investigated.
A relevant reduction of blood pressure (BP) in placebo-treated control groups is a phenomenon often observed in pharmacological studies of hypertension. This effect was shown to differ from spontaneous remission tendencies and regression to the mean effect by comparing placebo groups with untreated controls. However, it is not fully understood whether these effects are due to a global reaction of the autonomous nervous system (affecting the overall organ systems of the body) or a specific reaction (affecting the cardiovascular system only). We therefore aim to differentiate specific effects (reduction of blood pressure) from global effects (e.g. changes in electrodermal and gastric activity). In our study we aim to test the following hypotheses: 1. Placebo administration leads to a significant changes of blood pressure compared with untreated controls. 2. The direction of blood pressure change depends on the type of suggestion (either decrease or increase) 3. This effect is specific for blood pressure; changes in electrodermal and gastric activity do not differ between groups. 4. The placebo response can be enhanced by a prestige intervention (information about the suggested drug action given by doctor or in written form).
Earlier investigations have detected low levels of macular pigment (MP) in the center of the fovea and a halo of MP at a higher eccentricity in persons with type 2 idiopathic juxtafoveal teleangiectasia (MACTEL)[Helb H-M, Charbel Issa P, Pauleikhoff D, Scholl HPN, Holz FG, MacTel-Study Group. Macular Pigment Density and Distribution in Patients with Macular Telangiectasia. ARVO Annual Meeting 2006, Fort Lauderdale, 30.04.-5.05.2006. Program # 5701/B795]. To date it is not known whether the total MP is reduced in MACTEL or whether even more MP accumulates at higher eccenticities compared to healthy probands. With the suggested study we aim to 1. investigate Lutein and Zeaxanthin serum levels in MACTEL probands 2. investigate and quantify MP at the posterior pole of MACTEL probands 3. detect possible changes of MP concentration and distribution following supplementation with Lutein and Zeaxanthin
