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.
Percutaneous edge-to-edge repair of the mitral valve has been shown to be a safe and effective alternative treatment option for selected patients at high risk for cardiac surgery. Patients with recurrent mitral regurgitation after surgical mitral valve repair (sMVR) are per se at increased risk for another cardiac surgery. The purpose of this multicenter retrospective analysis of patients treated with a MitraClip® after sMVR, is to evaluate the effectiveness and durability of this minimally invasive treatment option in this subset of patients.
In this study the investigators sonicate the bearing components of the explanted hip prosthesis which allows highly sensitive detection of in vivo biofilms (qualitatively and quantitatively). The hip prosthesis bearing components are composed from different material. The purpose of this study is to analyse the resistance against biofilm adhesion of ceramic, metal and polyethylene prosthesis components through microbiologic analysis of sonicates.
Generation of a common European database and biobank Continous assessment and implementation of guidelines and treatment protocols Establishment of a large observational cohort of chILD patients Determination the value of outcomes used in child Assess treatment variations used, deliver data from defined protocols and linked outcomes
This is a Phase II, multicentre, open-label, randomized, and controlled study, evaluating the efficacy and safety of combined modularized treatment of treosulfan, pioglitazone and clarithromycin in patients with with squamous and non- squamous cell lung cancer, respectively after platin failure.
Obsessive-Compulsive Disorder (OCD) is among the most disabling psychiatric disorders as more than 40% of patients are resistant to the standard pharmacological and psychotherapy approaches and about 10% show severe disability and require institutionalization. These resistant patients may benefit from new surgical therapeutic approaches such as Deep Brain Stimulation (DBS) using high frequency stimulation of specific cerebral regions to modulate neural networks. Although promising, these results need nevertheless to be replicated and confirmed within a larger cohort of patients and considering a different main objective, instead of clinical improvement only. Indeed, despite a positive treatment response, adaptive functioning and quality of life may continue to be negatively impacted in OCD. Thus beyond symptom reduction, health-related quality of life (QoL) represents a more important objective of a treatment, as it includes both the individual's functional status and the individual's subjective perception of the impact of the illness on the patient's life. STN DBS induces significant clinical improvement, which may not be proportional to the QoL gain. Consequently, QoL appears to be a better outcome to target in the coming studies than clinical improvement alone. THe investigators thus propose a prospective study assessing the QoL changes of resistant OCD patients under STN DBS+BMT versus Best Medical Treatment (BMT) at 12 months, in order to assess the DBS induced gain in QoL in BMT-managed patients versus BMT alone.
The study would examine by hypericin-supported Fluoreszenzlaparoskopy in terms of tumor size, number and location of the combination of photodynamic diagnosis (PDD) and therapy (PDT) with regard to the detection of peritoneal metastases of locally advanced gastric cancer at 50 adult patients.
Screening colonoscopy is considered the gold standard for adenoma detection in the colon. However, it has been shown that a considerable number of polyps can be missed during screening colonoscopy. Until now the endoscopist himself is responsible for the detection of adenomatous polyps. No automatic tools are available supporting the colonoscopist to detect lesions. Recently, a computer program was developed that can be used to recognize and extract suspicious structure from colonoscopy video sequences. The program was built to automatically detected colonic polyps and to highlight the polyps by colour marking. The program was now refined so that the respective structures can be highlighted during real time colonoscopy. The aim of this feasibility study is to test whether the software is applicable during real time colonoscopy.
Although gastroenteropancreatic neuroendocrine neoplasia (GEP-NEN) were considered for years as rare tumors, their incidences are increasing. Due to their potential of early metastases and their heterogenous response to therapy, these tumors are important clinical entities. A major problem remains the impossibility to adequately predict tumors' response to treatment, precluding an individualized therapy. Further, there is no method to efficiently screen these tumors. Protein based analyses (proteomic analyses) gain in interest as methods to address this problematic. The present study was designed to investigate epidemiologic data of patients with GEP-NEN and to answer following questions using proteomic analysis applied to existing pathology specimens (paraffin-embedded specimens, FFPE): is it possible to explore protein signatures in this type of tumors? Is the response to therapy predictable using specific protein signatures? Is the tumor's tendency to metastasize related to specific protein signatures?
SPECTA is a quality assured platform for collecting clinicopathologically annotated biological material, imaging data, operative images, environmental assessment, questionnaires as well as patient-reported outcomes from cancer patients to support biospecimen-based translational research and clinical cancer research, including biomarker discovery to improve the understanding of tumor biology and cancer patients care.
It is the aim of this project to develop and validate a German language screening questionnaire for symptoms of respiratory muscle weakness and sleep-disordered breathing (SDB) in patients with neuromuscular disorders.
