Analysis of risk factors for neurological dysfunction in patients with acute aortic dissection type A: data from the German Registry for Acute Aortic…

2012

OBJECTIVES: Acute aortic dissection type A (AADA) is associated with major adverse events, such as transient or persistent neurological dysfunction (ND), which may be patient-, disease- or surgery-related. There is a lack of consensus regarding risk factors for ND in AADA patients. The aim of this study was to analyse and identify risk factors for new postoperative ND after aortic repair for AADA. METHODS: Between July 2006 and June 2010, 2137 AADA patients were enrolled in the multi-centre, prospective German Registry of AADA (GERAADA). Perioperative data were prospectively gathered from 50 institutes in Austria, Switzerland and Germany, and multivariate logistic regression analysis was pe…

Disease Burden of Rotavirus Gastroenteritis in Children Residing in Germany: A Retrospective, Hospital-based Surveillance.

We compared the clinical features and events occurring 30 days after surgery…

Participation in adjuvant clinical breast cancer trials: Is there a difference in survival compared to guideline adherent adjuvant treatment? A retro…

2012

1082 Background: Clinical trials (CT) usually compare a standard treatment regime versus innovative new substances or regimens. However participation in CT is available for only few patients and exclusion criteria is usually very strict. Therefore this study tries to answer the following questions: (1) Does participation in adjuvant CT improve survival in breast cancer (BC)? (2) Is there a difference in survival compared to guideline adherence and what is the role of the other treatments surrounding adjuvant breast cancer treatment? Methods: This German multi-center [17 participating hospitals all are certified as breast cancer centers] retrospective cohort study called BRENDA (BRENDA = qu…

Participation in adjuvant clinical breast cancer trials: does study participation improve survival compared to guideline adherent adjuvant treatment?…

2012

Abstract Adjuvant clinical trials (CTs) usually compare a standard treatment regime versus an innovative new substance or regimen. Participation in CT however, is available for only few patients and exclusion criteria are usually very strict. Therefore we used an unselected patient cohort to investigate the following questions: (1) Is participation in adjuvant CT associated with improved survival in breast cancer (BC)? (2) What is the impact of guideline conform therapy on survival in BC compared to that of participants in CT? Does guideline-conform adjuvant treatment provide an equal impact? Material and methods This German retrospective multi-centre cohort study included 9433 patients wit…

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 …

Integrative Genome-Scale DNA Methylation Analysis of a Large and Unselected Cohort Reveals 5 Distinct Subtypes of Colorectal Adenocarcinomas

2019

BACKGROUND & AIMS: Colorectal cancer is an epigenetically heterogeneous disease, however, the extent and spectrum of the CpG island methylator phenotype (CIMP) is not clear. METHODS: Genome-scale methylation and transcript expression were measured by DNA Methylation and RNA expression microarray in 216 unselected colorectal cancers, and findings were validated using The Cancer Genome Atlas 450K and RNA sequencing data. Mutations in epigenetic regulators were assessed using CIMP-subtyped Cancer Genome Atlas exomes. RESULTS: CIMP-high cancers dichotomized into CIMP-H1 and CIMP-H2 based on methylation profile. KRAS mutation was associated significantly with CIMP-H2 cancers, but not CIMP-H1 can…

Intraoperative neuroprotective drugs without beneficial effects? Results of the German Registry for Acute Aortic Dissection Type A (GERAADA).

2013

OBJECTIVES: Cerebral protection during acute aortic dissection Type A (AADA) surgery may be affected by perfusion strategies and ischaemic protective drugs. METHODS: We analysed the impact of intraoperative barbiturate, steroid and mannitol use and adjunctive cerebral perfusion (CP), on 30-day mortality and new postoperative mortality-corrected permanent neurological dysfunction (PNDmc) in the German Registry for Acute Aortic Dissection Type A. RESULTS: Two thousand one hundred and thirty-seven AADA patients were registered over a 4-year period. The overall 30-day mortality was 16.9%, and the overall rate of PNDmc was 10.0%. A total of 48% of patients received no neuroprotective drugs (cont…

Effects of stepped psychooncological care on referral to psychosocial services and emotional well-being in cancer patients: A cluster-randomized phas…

2016

Objective Emotional distress in cancer patients often goes unnoticed in daily routine; therefore, distress screening is now recommended in many national guidelines. However, screening alone does not necessarily translate into better well-being. We examined whether stepped psychooncological care improves referral to consultation-liaison (CL) services and improves well-being. Methods In a cluster-randomized trial, wards were randomly allocated to stepped versus standard care. Stepped care comprised screening for distress, consultation between doctor and patient about the patient's need for CL services, and provision of CL service. Primary outcomes were referral to psychosocial services and em…

In vitro model for DNA double‐strand break repair analysis in breast cancer reveals cell type–specific associations with age and prognosis

2016

Dysfunction of homologous recombination is a common denominator of changes associated with breast cancer-predisposing mutations. In our previous work, we identified a functional signature in peripheral blood lymphocytes from women who were predisposed that indicated a shift from homologous recombination to alternative, error-prone DNA double-strand break (DSB) repair pathways. To capture both hereditary and nonhereditary factors, we newly established a protocol for isolation and ex vivo analysis of epithelial cells, epithelial-mesenchymal transition cells (EMTs), and fibroblasts from breast cancer specimens (147 patients). By applying a fluorescence-based test system, we analyzed the error-…

Supracoronary ascending aortic replacement in patients with acute aortic dissection type A: What happens to the aortic root in the long run?

2013

ObjectiveOur objective was to determine long-term outcome predictors for patients with acute aortic dissection type A (AADA) and aortic root involvement.MethodsFrom 2001 through 2009, 119 of 152 patients operated on for AADA at a tertiary medical center underwent supracoronary ascending aortic replacement (52 women; mean age, 61 ± 15 years). Those with at least 1-year follow-up (n = 97) were retrospectively assessed for preoperative aortic root disease. Follow-up data were assessed for evidence of new-onset aortic root disease by computed tomography and echocardiography, and for reoperation for aortic root disease.ResultsMedian follow-up was 33.8 months (range, 0-112 months). Twenty-six (27…

Construct Validity and Population-Based Norms of the German Brief Resilience Scale (BRS).

2018

Abstract. The Brief Resilience Scale (BRS) measures the ability to recover from stress. To provide further evidence for construct validity of the German BRS and to determine population-based norms, a large sample (N = 1,128) representative of the German adult population completed a survey including the BRS and instruments measuring perceived stress and the resilience factors optimism, self-efficacy, and locus of control. Confirmatory factor analyses showed best model fit for a five-factor model differentiating the ability to recover from stress from the three resilience factors. On the basis of latent and manifest correlations, convergent and discriminant validity of the BRS were fair to g…

Indikatoren schulischen Wohlbefindens bei gesunden und chronisch kranken Kindern: Psychometrische Prüfung und Validierung adaptierter FEESS-Skalen

2020

Zusammenfassung. Das schulbezogene Wohlbefinden (SBWB) ist eine wichtige Voraussetzung für schulischen Erfolg. Trotzdem existieren – insbesondere mit Blick auf die Erfassung des SBWB von Erstklässlern – im deutschsprachigen Raum nur vereinzelt Studien. Dies lässt sich möglicherweise durch das Fehlen geeigneter Instrumente begründen. Dies gilt auch und insbesondere dann, wenn der Gesundheitszustand der Kinder berücksichtigt werden soll. Das Ziel der vorliegenden Arbeit besteht in der Validierung des adaptierten Fragebogens zur Erfassung von emotionalen und sozialen Schulerfahrungen (FEESS 1 – 2; Rauer & Schuck, 2004 ) mit Fokus auf die Eignung des Instruments für chronisch kranke und ge…
