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 study aims to compare the results of pulmonary vein isolation (PVI) with a single technology approach in patients suffering from paroxysmal atrial fibrillation (PAF) with patients who have persistent AF of less than 3 months. Many studies have shown that electrical reconnection of the pulmonary veins following the index procedure can occur in up to 40% of targeted veins leading to a recurrence of PAF. Endoscopically guided laser ablation utilising the HeartLight system (CardioFocus Inc., USA) has been shown to be safe and effective and has also shown promising rates of durable isolation compared to point by point radio frequency techniques. However, the impact of employing this technique for patients with persistent AF has not yet been reported. The study hypothesis is that there will be no statistically significant difference between the results of PVI in the two groups of patients.
Background: For treating deep caries lesions, selective or stepwise, i. e. one- and two-step incomplete excavation seems advantageous compared with complete caries removal. However, current evidence regarding the success, as defined by not requiring any re-treatments, or survival of teeth after different excavations is insufficient for definitive recommendation, especially when treating deciduous teeth. Moreover, restoration integrity has not been comparatively analyzed longitudinally, and neither patients', dentists' or parents' preferences nor the clinical long-term costs emanating from both initial and re-treatments have been reported yet. Our primary hypothesis is that success rates differ significantly between selectively and stepwise excavated teeth. Secondary hypotheses are that restoration integrity is assumed to significantly differ between selectively and stepwise excavated teeth.
Relapse is a major risk in substance abuse disorders, which is closely related to craving for a substance, describing a strong urge for consumption. Cue-exposure therapy is an intervention aiming at the reduction of perceived craving by repeated confrontation. It is based on the assumption that craving drops after repeated exposure without the reinforcing experience elicited by consumption. In the present study, patients with alcohol dependency take part in nine cue-exposure training sessions. Each session consists of mood induction reflecting a high risk situation with subsequent in vivo confrontation with one's preferred alcoholic beverage followed by the training of coping strategies. During the cue-exposure, patients focus on perceiving automatic responses to alcohol-related cues. We hypothesize that especially patients exhibiting initially high reactions to such cues should profit from this intervention the most. The reactions are measured on a subjective (craving) and physiological level (hemodynamics of the prefrontal cortex, heart rate variability, electrodermal activity). Furthermore, we want to strengthen the expected training effects during the cue-exposure by an activating transcranial direct current stimulation of the dorsolateral prefrontal cortex, which has been shown to be hypoactive in substance abuse disorders. We investigate how the cue-exposure training affects the processing of alcoholic cues (cue-reactivity) and its relation to clinical symptoms of alcohol dependency.
A multicenter, open-label Phase 2b study of selinexor (KPT-330) in participants with relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL) who have no therapeutic options of demonstrated clinical benefit.
The purpose of this study is to determine the safety, performance and efficacy of the Hyperion™ Occluder Systems during treatment of ASD and PDA patients.
Evaluation if physostigmine reduces symptoms in patients who has developed a delirium in Intensive care after a surgery
The main objectives of the PATHOS study are: To assess whether swallowing function can be improved following transoral resection of HPV-positive OPSCC, by reducing the intensity of adjuvant treatment protocols. The aim is to personalise treatment, based on disease biology (HPV status and pathology findings), to optimise patient outcomes. To demonstrate the non-inferiority of reducing the intensity of adjuvant treatment protocols in terms of overall survival in the reduced intensity treatment arms.
Cardiac surgery leeds to a systematic inflammatory response induced by the surgical trauma and the use of the cardiopulmonary bypass (CPB). Activation of inflammatory cascades can cause a systemic inflammatory response syndrome (SIRS) which is associated with increased morbidity and mortality. Therefore, strategies to reduce the inflammatory response have a potential benefit for cardiac surgery patients. The clinical benefit of reducing proinflammatory cytokines such as IL-6, Il-8 and TNF-a with the use of a cytokine adsorbing circuit (Cytosorb) during CBP remains unclear. Therefore, the investigators conduct this prospective, observational pilot study to determine the clinical impact of the use of a cytokine adsorbing circuit during CBP.
In this study the investigators hypothesize that pathological alterations in adipose tissue biology already occur during the development and progression of obesity in children and adolescents. The investigators aim to identify and characterize mechanisms and molecular targets that affect the development of adipose tissue and ensuing obesity in childhood and adolescence.
Aim of the scientific analysis is to find biological factors (biomarkers) allowing a prediction of disease progression and a better choice of therapy. After diagnosis the kidney and the tumor will be removed by standard surgery followed by drug therapy. Within surgery remaining tumor tissue will be used for the scientific analysis. In case of disease progression during the drug treatment the drug therapy will be changed. Before therapy change a small tissue sample will be collected for molecular diagnostics. This will be done by puncture through the skin under local anesthesia. Blood samples taken before surgery and at the time of first and second disease progression will also be used for molecular-biological analysis. As there is no clear recommendation for drug therapy after disease progression this study should serve to determine an individual therapy on the basis of the molecular profile and the molecular changes. As the tumor disease changes and developes resistance to drugs, analysis at the time of disease progression shall identify biological factors which will predict a likelihood response to a specific drugs. This shall allow to give the patient an individual therapy.
