Etiology-specific assessment of predictors of long-term survival in chronic systolic heart failure.

Background: We sought to identify prognostic factors of long-term mortality, specific for the underlying etiology of chronic systolic heart failure (CHF).

Methods And Results: Between 1995 and 2009 baseline characteristics, treatment and follow-up data from 2318 CHF-patients due to ischemic (ICM; 1100 patients) or dilated cardiomyopathy (DCM; 1218 patients) were prospectively compared. To calculate hazard ratios with 95%-confidence intervals cox regression was used.

Burnout and effort-reward-imbalance in a sample of 949 German teachers.

Objectives: High rates of teachers' premature retirement initiated a research investigating their occupational burden. The aim of this study was to elaborate on and extend previous investigations exploring (1) teacher burnout and (2) the relationship between teachers' efforts and their rewards.

Methods: A sample of 949 German teachers in 10 Gymnasien (grammar schools) and 79 Hauptschulen (secondary modern schools) was investigated applying the Maslach Burnout Inventory (MBI-D) and the Effort Reward Imbalance Inventory (ERI).

Working conditions, adverse events and mental health problems in a sample of 949 German teachers.

Objectives: The aim of this study was (1) to explore in detail the working load of teachers, (2) to analyse the extent of negative or threatening school-related events teachers are confronted with, and (3) to evaluate mental health strain by applying the general health questionnaire (GHQ).

Methods: A sample of 949 teachers in 10 grammar schools (German: Gymnasien) and 79 secondary modern schools (German: Hauptschulen) was investigated applying (1) a questionnaire covering different aspects of the occupational burden and threatening school-associated events and (2) the general health questionnaire (GHQ-12).

Results: Based on what teachers indicated in the questionnaire, full-time teachers work more than 51 h weekly.
