[The controversy over early diagnosis of Alzheimer's disease: A literature review of the advantages and disadvantages].

Background: The continuum of Alzheimer's disease (AD) comprises three stages: the pre-clinical stage (with few to no subjective symptoms), the prodromal stage (measurable mild cognitive impairment) and the final stage of clinically manifest (AD) dementia. Neuropathological correlates in accordance with these stages have been found with varying frequency. The aim of early AD diagnosis is to determine such correlates in these preclinical and prodromal stages and to determine the probability of the manifestation of a later AD dementia.

[Database indexing of health science journals from the German-speaking area: A journal analysis].

Background: Journal hand searching offers the possibility to complement a literature search as part of systematic reviews and other evidence syntheses. Hand searching is indicated in cases where scientific journals with potentially relevant publications addressing the research question are not indexed in a literature database. However, it is often unclear whether these journals are actually indexed, and when they are, in which literature databases.

Serotonin transporter dependent modulation of food-seeking behavior.

The olfactory pathway integrates the odor information required to generate correct behavioral responses. To address how changes of serotonin signaling in two contralaterally projecting, serotonin-immunoreactive deutocerebral neurons impacts key odorant attraction in Drosophila melanogaster, we selectively alter serotonin signaling using the serotonin transporter with mutated serotonin binding sites in these neurons and analyzed the consequence on odorant-guided food seeking. The expression of the mutated serotonin transporter selectively changed the odorant attraction in an odorant-specific manner.

The Effectiveness of Biographical Approaches in Long-Term Care: A Systematic Review.

Background And Objectives: Older adults in long-term residential aged care experience loneliness and reduced quality of life (QoL). Biographical approaches use the recall of the past events to increase self-efficacy, promote acceptance, and improve QoL. The aim of the systematic review was to examine the effectiveness of biographical approaches in improving the QoL of older adults in long-term residential aged care.
