Background: The aim of this study was to clarify the engagement status of meaningful activities (MA) and its association with behavioural and psychological symptoms of dementia (BPSD) among people with early-onset dementia (EOD).
Methods: This cross-sectional study included 367 facilities that provide long-term care insurance (LTCI) services in Sapporo, Japan. A questionnaire was sent to these facilities to determine whether they had ever cared for people with EOD who developed dementia before the age of 65 and used LTCI services.
Article Synopsis
- Self-disclosure refers to sharing personal experiences and feelings, which is linked to mental health and a person's openness.
- This study focused on older adults in Japan, analyzing how self-disclosure relates to frailty, a condition indicating reduced physical and psychological strength, using a new questionnaire designed for this purpose.
- Results showed that frail individuals tended to disclose less about positive life events, motivations, and relationships, suggesting that enhancing self-disclosure could help prevent frailty and support better mental health among seniors.
Article Synopsis
- The study examined the photophysical behavior of the benzimidazolium derivative BID in different environments including water, organic solvents, and synthetic saponite.
- The fluorescence quantum yield of BID was significantly higher on the saponite surface (0.91) compared to water (0.010), a phenomenon termed "surface-fixation induced emission (S-FIE)."
- The findings suggested that the enhanced fluorescence was due to increased radiative deactivation rate constants and a dramatic decrease in non-radiative deactivation rate constants on the saponite surface, highlighting the impact of nanosheets.
Triarylamine-substituted benzimidazoliums (BI-PhNAr), new electron donor-acceptor dyad molecules, were synthesized. Their photocatalytic properties for reductive organic transformations were explored using absorption and fluorescence spectroscopy, redox potential determinations, density functional theory calculations, transient absorption spectroscopy, and reduction reactions of selected substrates. The results show that irradiation of BI-PhNAr promotes photoinduced intramolecular electron transfer to form a long-lived (∼300 μs) charge shifted state (BI-PhNAr).

Preventing frailty is imperative to maintaining productive roles of older adults. Therefore, this study aimed to examine the association between productive roles and frailty factors among community-dwelling older adults.

From January to March 2014, semi-structured interviews were conducted with 18 participants with mental illness living in the community in Japan. The qualitative data were analyzed using a modified grounded theory approach.
