BACKGROUND: In patients with chronic heart failure (CHF) increasing levels of total serum cholesterol are associated with improved survival - while statin usage is not. The impact of statin treatment on the "reverse epidemiology" of cholesterol is unclear. METHODS: 2992 consecutive patients with non-ischemic CHF due to left ventricular systolic dysfunction from the Norwegian CHF Registry and the CHF Registries of the Universities of Hull, UK, and Heidelberg, Germany, were studied...

BACKGROUND: The WHO classification of brain tumours describes 15 subtypes of meningioma. Nine of these subtypes are allotted to WHO grade I, and three each to grade II and grade III. Grading is based solely on histology, with an absence of molecular markers. Although the existing classification and grading approach is of prognostic value, it harbours shortcomings such as ill-defined parameters for subtypes and grading criteria prone to arbitrary judgment. In this study, we aimed for a comprehensive characterisation of the entire molecular genetic landscape of meningioma to identify biologically and clinically relevant subgroups...

Objective: After passing of the National Competency-based Learning Objectives Catalogue in Medicine (Nationaler Kompetenzbasierter Lernzielkatalog Medizin, [NKLM, retrieved on 22.03.2016]), the German medical faculties must take inventory and develop their curricula. NKLM contents are expected to be present, but not linked well or sensibly enough in locally grown curricula. Learning and examination formats must be reviewed for appropriateness and coverage of the competences. The necessary curricular transparency is best achieved by systematic curriculum mapping, combined with effective change management...

Background: Primary health care in rural regions is currently undergoing a global crisis in respect of the next generation of practitioners. National and international recommendations advise placing greater emphasis upon practical skills and competences in medical studies. It is also in the interest of training the next generation to include mentoring and longitudinal integration of contact to teaching practices for general medicine in an early stage. Consequently, the General Practice Class (KAM) was introduced in Halle in 2011 as an elective with 20 individually mentored students per year, beginning with the first subject-related semester...

Salmonella enterica serovar Heidelberg (S. Heidelberg) is one of the pathogens most frequently detected in recent years in food products from animals; here, we examine the acid tolerance of this strain. Mild acid (pH5.5-5.0) induced a strong acid resistance in S. Heidelberg; the induced acid resistance improved within 0.5-6h and resulted in >95% cell survival following challenge in pH3.0 medium. Addition of lysine or arginine to pH2.5 acid challenge medium significantly improved the survival of S. Heidelberg; lysine induced the largest increase in survival...

Metagenomics has become an integral part of defining microbial diversity in various environments. Many ecosystems have characteristically low biomass and few cultured representatives. Linking potential metabolisms to phylogeny in environmental microorganisms is important for interpreting microbial community functions and the impacts these communities have on geochemical cycles. However, with metagenomic studies there is the computational hurdle of 'binning' contigs into phylogenetically related units or putative genomes...
