[Health and Social Status in Hamburg's Urban Quarters - An Approach to Mapping Social Status with Health-Related Routine Data].

Aim Of The Study: The aim of this study was to test an innovative approach to the small-scale and social situation-sensitive localisation and analysis of health-related routine data. For this purpose, SHI billing data and deployment data of the ambulance service were supplemented with a small-scale neighbourhood-related indicator of the social situation of the place of residence and/or deployment as a proxy for the personal social situation.

Methods: Anonymised accounting data from three statutory health insurances and deployment data from the rescue service of the Hamburg fire brigade, each from the year 2017, were used.

[Physicians at the Interface to the Non-Medical Sector of Home- and Community-Based Services for People with Dementia].

Objective: The study examined the function of physicians between the medical and nonmedical sector of home- and community-based services in the ambulatory care of people with dementia and their relatives. Therefore, the study took a differentiated look at the status quo of physicians' activities regarding non-medical home- and community-based services as well as approaches for optimizing the current situation from the physicians' perspective.

Methods: An explorative cross-sectional study was conducted using a standardized postal survey (based on a qualitative preliminary study with 6 physicians).

Polar Nature of Biomimetic Fluorapatite/Gelatin Composites: A Comparison of Bipolar Objects and the Polar State of Natural Tissue.

The correspondence of the state of alignment of macromolecules in biomimetic materials and natural tissues is demonstrated by investigating a mechanism of electrical polarity formation: An in vitro grown biomimetic FAp/gelatin composite is investigated for its polar properties by second harmonic (SHGM) and scanning pyroelectric microscopy (SPEM). Hexagonal prismatic seed crystals formed in gelatin gels represent a monodomain polar state, due to aligned mineralized gelatin molecules. Later growth stages, showing dumbbell morphologies, develop into a bipolar state because of surface recognition by gelatin functionality: A reversal of the polar alignment of macromolecules, thus, takes place close to that basal plane of the seed.

Delineation of brain tumor extent with [11C]L-methionine positron emission tomography: local comparison with stereotactic histopathology.

Purpose: Methyl-[11C]L-methionine ([11C]MET) positron emission tomography (PET) in brain tumors reflects amino acid transport and has been shown to be more sensitive than magnetic resonance imaging in stereotactic biopsy planning. It remains unclear whether the increased [11C]MET uptake is limited to solid tumor tissue or even detects infiltrating tumor parts.

Experimental Design: In 30 patients, a primary or recurrent brain tumor was suspected on magnetic resonance imaging.
