Survival of ovarian cancer patients in Germany in the early 21st century: a period analysis by age, histology, laterality, and stage.

2012

Population-based studies on ovarian cancer providing survival estimates by age, histology, laterality, and stage have been sparse. We aimed to derive the most up-to-date and detailed survival estimates for ovarian cancer patients in Germany. We used a pooled German national dataset including data from 11 cancer registries covering 33 million populations. A total of 21 651 patients diagnosed with ovarian cancer in 1997-2006 were included. Period analysis was carried out to calculate the 5-year relative survival (RS) for the years 2002-2006. Trends in survival between 2002 and 2006 were examined using model-based period analysis. Age adjustment was performed using five age groups (15-44, 45-5…

Death certificate only proportions should be age adjusted in studies comparing cancer survival across populations and over time

2015

Abstract Background The proportion of cases notified by death certificate only (DCO) is a commonly used data quality indicator in studies comparing cancer survival across regions and over time. We aimed to assess dependence of DCO proportions on the age structure of cancer patients. Methods Using data from a national cancer survival study in Germany, we determined age specific and overall (crude) DCO proportions for 24 common forms of cancer. We then derived overall (crude) DCO proportions expected in case of shifts of the age distribution of the cancer populations by 5 and 10 years, respectively, assuming age specific DCO proportions to remain constant. Results Median DCO proportions acros…

Assessing Planning Ability Across the Adult Life Span: Population-Representative and Age-Adjusted Reliability Estimates for the Tower of London (TOL-…

2015

Planning ahead the consequences of future actions is a prototypical executive function. In clinical and experimental neuropsychology, disc-transfer tasks like the Tower of London (TOL) are commonly used for the assessment of planning ability. Previous psychometric evaluations have, however, yielded a poor reliability of measuring planning performance with the TOL. Based on theory-grounded task analyses and a systematic problem selection, the computerized TOL-Freiburg version (TOL-F) was developed to improve the task's psychometric properties for diagnostic applications. Here, we report reliability estimates for the TOL-F from two large samples collected in Mainz, Germany (n = 3,770; 40-80 y…

International, multicenter evaluation of a new D-dimer assay for the exclusion of venous thromboembolism using standard and age-adjusted cut-offs.

2017

We sought to determine the test characteristics of an automated INNOVANCE D-dimer assay for the exclusion of pulmonary embolism (PE) and deep venous thrombosis (DVT) in emergency department (ED) patients using standard and age-adjusted cut-offs.Cross-sectional, international, multicenter study of consecutive patients with suspected DVT or PE in 24 centers (18 USA, 6 Europe). Evaluated patients had low or intermediate Wells PE or DVT scores. For the standard cut-off, a D-dimer result500 ng/ml was negative. For the age adjusted cut-off, we used the formula: Age (years) ∗ 10. The diagnostic standard was imaging demonstrating PE or DVT within 3 months. We calculated test characteristics using s…

Benefit of using an age-adjusted D-dimer cut-off

2015

Introduction: The association between a low-moderate pretest clinical probability and a negative D-dimer (DD) value is able to exclude the possibility of pulmonary embolism (PE). The value of DD seems to increase with age, reducing its specificity. Therefore, we intend to evaluate the usefulness of an age-adjusted cut-off value for age above 50 years, applying the formula suggested by Douma (age*10) set to our laboratory method (age*5) (1) . Patients and Methods: Observational, retrospective study from January to December 2011. DD test were performed to 1515 patients attended in the emergency room of our hospital according to the clinical suspicion made by the doctor who evaluated them. The…

Population Level Survival of Patients with Chronic Myeloid Leukemia in Germany in the Early 21st Century

2012

Abstract Abstract 759 Background: Chronic myeloid leukemia (CML) is a rare but highly treatable form of leukemia. Recent advances in the treatment of CML have dramatically improved survival in clinical trials. Prior work using the Surveillance, Epidemiology, and End Results (SEER) database in the United States (US) suggest that survival on the population level has increased, but still lags behind that seen in clinical trials1. In the past, evaluation of population level survival in other countries has been hampered by the lack of high quality data from a large enough population to evaluate trends in survival in this rare disease. Recently, a collaborative effort between the German Cancer Re…

Modelo predictivo preliminar para la identificación de pacientes con oportunidades de mejora farmacoterapéutica

2010

Objective: To develop a prediction model for identifying patients with the possibility of improving pharmacotherapy during the process of pharmaceutical validation of the prescription. Method: Cross-sectional study over two months, performed in the Internal Medicine and Infectious Disease divisions. Detecting opportunities for improving quality of pharmaco¬therapy is done by means of a pharmacist's validation of the prescription. Based on the information we obtained through this process, we performed a multivariate logistic regression analysis using as prognostic factors the demographic, pharmacotherapy and clinical variables related to identifying any drug-related problems (DRPs) in the pa…

Lung cancer survival in Germany: A population-based analysis of 132,612 lung cancer patients.

2014

Lung cancer is the most common cancer-related death worldwide. In Germany it accounts for 25% of cancer deaths in men, and 14% in women. The aim of this study is to provide an overview of 5-year relative survival by sex, age, histology, and tumour stage in Germany representing a population of 26.7 million people.The study is based on a pooled German dataset including data from 12 population-based cancer registries covering around one third of the German population. A total of 132,612 patients diagnosed with lung cancer from 2002 to 2010 were included in the analysis. Survival estimates for the time period 2007-2010 were calculated using period analysis. Differences in survival between sexes…

Ocular signs in Fabry disease have generally been regarded to be primarily of diagnostic value. We explored whether ocular findings, alone or in particular in combination with the α-galactosidase A gene mutation, have predictive value for disease severity. Data from the Fabry Outcome Survey (FOS), a large, global database sponsored by Shire, were selected for adult patients who had undergone ophthalmological examination. Three ocular signs were assessed: cornea verticillata, tortuous conjunctival and/or retinal vessels, and cataract. Fabry disease severity was measured using FOS Mainz Severity Score Index and modifications thereof. Ophthalmological data were available for 1203 (699 female, …

Gender-related disparities in the treatment and outcomes in patients with non-ST-segment elevation myocardial infarction: results from the Polish Reg…

2017

Introduction: Gender-related differences in the treatment of patients with non-ST elevation myocardial infarction (NSTEMI) have been reported in many previous studies despite the fact that an equal approach is recommended in all current guidelines. The aim of the study was to investigate whether gender-related discrepancies in the management of NSTEMI patients have changed. Material and methods: Between 2012 and 2014 a total of 66,667 patients (38.3% of whom were women) with the final diagnosis of NSTEMI were included into the retrospective analysis of the Polish Registry of Acute Coronary Syndromes (PL-ACS). Differences in clinical profile, treatment, and outcomes were analysed. Results: W…
