Outcome after surgery for acute aortic dissection type A in patients over 70 years: data analysis from the German Registry for Acute Aortic Dissectio…
2010
Objective: The number of elderly patients undergoing emergency surgery for acute aortic dissection type A (AADA) is rising. Published results report a higher risk for thesepatients comparedwith younger patients. The aim of our study wasto analyse the surgicaloutcomeof these patients and to identify those at risk. Methods: Between July 2006 and June 2009, 44 centres participating in the German Registry for Acute Aortic Dissection Type A (GERAADA) reported a total of 1558 patients. As many as 381 patients were between 70 and 80 years of age (septuagenarians), while 83 patients were 80 years and older (octogenarians). We compared the clinical features and events occurring 30 days after surgery…
Mortality in patients with acute aortic dissection type A: analysis of pre- and intraoperative risk factors from the German Registry for Acute Aortic…
2015
Acute aortic dissection type A (AADA) is an emergency with excessive mortality if surgery is delayed. Knowledge about independent predictors of mortality on surgically treated AADA patients is scarce. Therefore, this study was conducted to identify pre- and intraoperative risk factors for death.Between July 2006 and June 2010, 2137 surgically treated patients with AADA were enrolled in a multicentre, prospective German Registry for Acute Aortic Dissection type A (GERAADA), presenting perioperative status, operative strategies, postoperative outcomes and AADA-related risk factors for death. Multiple logistic regression analysis was performed to identify the influence of different parameters …
Assessing quality of care for the dying from the bereaved relatives' perspective: Using pre-testing survey methods across seven countries to develop …
2019
Background: The provision of care for dying cancer patients varies on a global basis. In order to improve care, we need to be able to evaluate the current level of care. One method of assessment is to use the views from the bereaved relatives. Aim: The aim of this study is to translate and pre-test the ‘Care Of the Dying Evaluation’ (CODETM) questionnaire across seven participating countries prior to conducting an evaluation of current quality of care. Design: The three stages were as follows: (1) translation of CODE in keeping with standardised international principles; (2) pre-testing using patient and public involvement and cognitive interviews with bereaved relatives; and (3) utilising …
Molecular Basis of Hereditary C1q Deficiency
1998
Abstract Complete selective deficiencies of the complement component C1q are rare genetic disorders which are associated with recurrent infections and a high prevalence of lupus erythematosus-like symptoms. The improvements in molecular biology techniques have facilitated the analysis of such genetic defects to a great extend. To date the basis of C1q deficiencies from 13 families have been studied at the genetic level. In each case single base mutations leading to either termination codons, frame shift or amino acid exchanges were thought to be responsible for these defects as no other aberrations were found. In addition to DNA analysis, conventional immunochemical and biochemical methods …
No evidence for an association of plasma homocysteine levels and refractive error – Results from the population-based Gutenberg Health Study (GHS)
2020
Purpose There is a strong association between severe hyperhomocysteinemia and myopia. Thus we studied the hypothesis that even moderately increased levels of homocysteine (Hcy) might be a potentially treatable risk factor for myopia. Methods The Gutenberg Health Study (GHS) is a population-based, prospective, observational cohort study in Germany, including 15,010 participants aged between 35 and 74 at recruitment. The baseline examination was conducted from 2007–2012. Refraction was measured using autorefraction (HARK 599, Carl Zeiss AG, Jena, Germany). Hcy was measured by an immunoassay. We included only phakic participants without a history of corneal surgery or corneal laser treatment. …
Characteristics and pathologies of the vitreo‐macular interface—results from the Gutenberg Health Study
2019
Purpose We aimed to determine the prevalence of characteristics and pathologies of the vitreo-macular interface within the general population. Methods The Gutenberg Health Study is a population-based study in Germany, including an ophthalmological examination with refraction, biometry and optical coherence tomography (OCT) imaging. Characteristics of the vitreo-macular interface were graded on volume scans including visibility of an epiretinal membrane, full-thickness macular hole, lamellar hole and pseudohole. Overall and age-specific prevalences including 95% confidence intervals [95%-CI] were calculated. Association analyses were conducted to determine systemic and ocular factors that ar…
Endovascular Aneurysm Sealing (EVAS) and Chimney EVAS in the Treatment of Failed Endovascular Aneurysm Repairs
2016
Purpose: To assess the technical success and clinical outcome of reinterventions using the Nellix Endovascular Aneurysm Sealing (EVAS) System to treat complications after endovascular aneurysm repair (EVAR). Methods: Fifteen consecutive patients (mean age 79 years; 14 men) with prior EVAR were treated with EVAS between March 2014 and December 2015 at 2 institutions. The failed prior EVARs included 13 bifurcated endografts, 1 bifurcated graft plus fenestrated cuff, and 1 tube endograft. Endoleaks were the predominant indications: type Ia in 10 and type III in 5 (3 type IIIa and 2 type IIIb). All patients presented with progressive aortic aneurysms (median 7.85-cm diameter; range 6.5–11). Ei…
Interest in meta-research in geriatric medicine: a survey of members of the European Geriatric Medicine Society
2020
To know the knowledge of the EuGMS members regarding meta-research, especially systematic reviews and meta-analyses. Interest in systematic reviews and meta-analyses is high and there is a demand for education on these topics in relation to geriatric medicine. We need more resources in the EuGMS for education for meta-research tailored for geriatric medicine. There has been an exponential increase in meta-research, especially in the branch dealing with systematic reviews [SRs] and meta-analyses [MAs]. However, the knowledge regarding these topics in geriatric medicine is still poorly explored. We therefore undertook a survey of the current knowledge and needs in meta-research in geriatrics.…
Impact of pulmonary embolism on in-hospital mortality of patients with ischemic stroke
2020
Pulmonary embolism (PE) is a frequent complication in immobile stroke patients and an important cause of death in stroke patients. We aimed to investigate predictors of PE and the impact of PE on survival of ischemic stroke patients.Patients were selected by screening the German nationwide inpatient sample (2005-2017) for ischemic stroke (ICD-code I63) and stratified for occurrence of PE (ICD-code I26). Impact of PE on mortality and predictors for PE in ischemic stroke patients were analysed.Overall, 2,914,546 patients were hospitalized due to ischemic stroke (50.5% females; 69.3% aged ≥70 years) in Germany 2005-2017. Among these, 0.4% had PE and 7.2% died during hospitalization. In-hospita…
A locus on 2p12 containing the co-regulated MRPL19 and C2ORF3 genes is associated to dyslexia.
2007
DYX3, a locus for dyslexia, resides on chromosome 2p11-p15. We have refined its location on 2p12 to a 157 kb region in two rounds of linkage disequilibrium (LD) mapping in a set of Finnish families. The observed association was replicated in an independent set of 251 German families. Two overlapping risk haplotypes spanning 16 kb were identified in both sample sets separately as well as in a joint analysis. In the German sample set, the odds ratio for the most significantly associated haplotype increased with dyslexia severity from 2.2 to 5.2. The risk haplotypes are located in an intergenic region between FLJ13391 and MRPL19/C2ORF3. As no novel genes could be cloned from this region, we hy…
