The primary aim of the DEDEMAS (Determinants of Dementia After Stroke) study is to identify predictors of post stroke dementia (PSD). A particular focus will be on biological markers (neuroimaging, biochemical markers derived from blood) and on interactions between vascular and neurodegenerative mechanisms. For this purpose patients with an acute stroke and without prior dementia will be followed for 10 years. Note: Starting from 01.01.2014 this study is expanded to a multi-centric design funded by the German Center for Neurodegenerative Diseases (The DZNE - Mechanisms of Dementia After Stroke (DEMDAS) Study). This includes the following study sites: DZNE/München - Institute for Stroke and Dementia Research, Klinikum der Universität München (Coordinator); DZNE/Berlin - Neuroscience Research Center - Campus Mitte Charité; DZNE/Bonn - Klinik und Poliklinik für Neurologie, Universitätsklinikum Bonn; DZNE/Göttingen - University Medical Center Göttingen; DZNE/Magdeburg - Universitätsklinikum Magdeburg.
The purpose of this study is to evaluate the clinical performance of a decompression using the FDA cleared iO-Flex® System on-label in treating patients with spinal stenosis and stable grade I degenerative lumbar spondylolisthesis using a precision estimate assuming a 55% positive response rate.
The purpose of this study is to evaluate the safety of deploying and implanting the Altura Abdominal Aortic Aneurysm (AAA) Endograft in the treatment of abdominal aortic aneurysms in subjects who are candidates for open surgical aneurysm repair.
Background: Patients undergoing hip fracture surgery are elderly and usually have co-morbidities; hence they are at risk for perioperative MI. Troponin is the gold standard for diagnosis of myocardial damage and currently the cornerstone of MI diagnosis. Perioperative troponin elevation is a poor prognosis factor. The significance of minor troponin elevation, detected by highly sensitivity troponin T assay, is unknown. Objectives: To determine the frequency of perioperative troponin T elevation using highly sensitivity troponin T assay, and to determine the clinical significance of this elevation. Methods: Serum Troponin T levels of patients undergoing hip fracture surgery will be tested prior to surgery 48 hrs and 72 hrs after surgery, using highly sensitivity troponin T assay. Patients will be followed for 1 year. Primary outcomes- The number of patients with elevated troponin levels perioperatively and cardiac mortality at 3 months, 6 months and 1 year.
The purposes of the study are - to determine which kind of supervised exercise intervention (aerobic endurance training versus strength endurance training versus combined aerobic endurance and strength endurance training) is more effective in improving the metabolic parameters in typ 2 diabetes patients - to investigate what kind of intervention is more successful in reduction of concomitant diseases and improving quality of life - to assess what kind of intervention induces highest effects in long term persistence of these positive changes
Hypothesis: Portable sleep testing of hospitalized medical inpatients suspected of having OSA is accurate in determining the need for positive airway pressure (PAP) therapy when compared to outpatient laboratory-based polysomnography. - Hospitalized medical inpatients referred for suspected OSA will be tested with a portable sleep apnea testing device during hospitalization. - These patients will then undergo an outpatient laboratory-based attended polysomnography after hospital discharge. - Results of the inpatient portable sleep apnea test will be compared to the outpatient laboratory-based polysomnography in terms of diagnostic accuracy.
This study focuses on Cardioprotective strategies.
This is a single, one time, limited dose infusion of Paclitaxel, that will potentially prevent recurrent stenosis secondary to intimal hyperplasia when compared to the control group at 10 months.
A Study to Evaluate the Safety and Feasibility of Transcranial MRI-Guided Focused Ultrasound Surgery in the Treatment of Brain Tumors
This screening study will address the lack of molecular strategies for the early detection of lung cancer and integrate those with epidemiological and imaging strategies. The hypothesis is that the repeated measure of biomarkers of risk obtained from the molecular analysis of biological specimens including those from bronchoscopy (bronchial brushings and biopsies) may contribute to the refinement of high-risk populations and allow an earlier clinical diagnosis. The goal of the investigators study is to provide screening for lung cancer in a high-risk population. In this prospective cohort it will be tested whether repeated measure of biomarkers of risk allows early detection of lung cancer.
