Aging and Elder Care in Japan: A Call for Empowerment-Oriented Community Development.

This article provides a brief overview of the situation of the elderly and their caregivers in Japan, including demographic changes in Japan, development and changes in long-term care policy that have targeted the poorly integrated community care system, and other challenges that the elderly and family caregivers face. Policy direction designed to address these issues is increasingly targeting care by the community versus support care by society (which was initially the main strategy). The potential of empowerment-oriented community development intervention strategies to decrease the gap between available institutional and formal community-based services and the needs of the elderly and their families in their efforts to meet late life challenges is described. The need for an increased role of social workers in community development interventions is explored and strategies are suggested.

Coping with late-life challenges: Development and validation of the care-receiver efficacy scale.

PURPOSE: Measures are lacking that address the challenges that people think they face in their roles as elderly care receivers. However, the development of a sense of efficacy in this role by mentally competent care receivers is critical to successful partnerships between caregivers and care receivers. The purpose of this article is to report the development and psychometric analysis of the Care-Receiver Efficacy Scale (CRES). DESIGN AND METHODS: Content validity, internal consistency reliability, factor structure, and convergent validity were assessed through a pilot study, expert review, and field administration with 177 participants. RESULTS: Results suggest that the CRES comprises five subscales, with strong reliability evidenced for three subscales but marginal reliability for the remaining two. Strong support was found for content validity from expert review and moderate support from the relationship between empirical and expert judgment of item location. Support for validity also was found from correlation with the Geriatric Depression Scale-Short Form and the Philadelphia Geriatric Center Morale Scale. IMPLICATIONS: The CRES may be useful as an outcome measure for psycho-socio-behavioral interventions aimed at increasing the capacity of care receivers to direct and improve their own care. Future measure revision and validation are important to optimize its utility.

Isolation of 8-hydroxyglycitein and 6-hydroxydaidzein from soybean miso.

We isolated from soybean miso 8-hydroxyglycitein and 6-hydroxydaidzein as DPPH-radical scavengers, and elucidated their chemical structures by mass spectrometric, and (1)H- and (13)C-NMR spectrosopic analyses. These compounds showed DPPH-radical scavenging activity as high as that of alpha-tocopherol, 8-hydroxygenistein and 8-hydroxydaidzein. This is the first report of the isolation of 8-hydroxyglycitein from a natural source.

Antimutagenic activity of 8-hydroxyisoflavones and 6-hydroxydaidzein from soybean miso.

The antimutagenic activity of four isoflavones isolated from soybean miso toward three kinds of mutagens, AF-2, MNNG, and Trp-P-1, was evaluated by the Ames test. 8-Hydroxyisoflavones had greater suppressive potency than that of daidzein, and 6-hydroxydaidzein had almost the same activity as daidzein. These results indicated the number of hydroxy and methoxy groups and the position of these functional groups were important for antimutagenic activity.
