Needs of persons with dementia and their family caregivers in dementia cafés.

BACKGROUND AND AIMS: Several studies have shown the effectiveness and diversity of dementia cafés, whereas there are few published articles in academic research focusing on what persons with dementia and their family caregivers need and whether the services provided satisfy their needs. This study aimed to identify the needs of persons with dementia and their family caregivers participating in dementia cafés in Japan. METHODS: Interviews and participant observations were conducted in nine dementia cafés. Study participants were persons with dementia, their caregivers, and the staff in dementia cafés. Data were analysed using qualitative content analysis. RESULTS AND DISCUSSION: A total of 24 participants were recruited. Needs for persons with dementia were subdivided into five categories: to express their feelings about their current condition; to be accommodated through consideration of their physical and cognitive status; for changes in their health conditions to be noticed; to enjoy entertainment; and to keep in touch with others inside and outside of the dementia café. Needs for family caregivers were subdivided into four subcategories: to express their feelings such as anxiety and guilt and complaints regarding caregiving; to consult about difficulties in daily life; to listen to other family caregivers' experiences; and to keep in touch with others inside and outside of the dementia café. The needs of persons with dementia and family caregivers differ partly. CONCLUSIONS: Dementia cafés should create programmes and comfortable environments answering to the differences of their needs.

Transport of Oligopeptide from Aqueous Phase to Span 80 Reverse Micelles in Microdroplet Array.

The partitioning of water and tetramethylrhodamine-conjugated-10-residue oligopeptides from the aqueous phase of microdroplets into Span 80 reverse micelles was observed by utilizing microdroplet arrays. Each peptide was dissolved in phosphate buffer saline, and initially encapsulated in arrayed droplets. An organic phase containing the reverse micelles was added to the microdroplets. Here, the hydration degree of the reverse micelle was adjusted by contact of the organic phase with a 1.0 M NaCl aqueous solution or with a phosphate buffer saline before combining it with the microdroplets. For micelles treated with a 1.0 M NaCl, significant water transport from the microdroplet to the micelle was observed, and peptide with low solubility in water was transported to the reverse micelles, while those with high solubility in water were not. For micelles treated with phosphate buffer saline, the water transport was minimal, and no significant peptide transport was observed. These results suggest that the partitioning of low-solubility oligopeptides requires accompanying water transport to the reverse micelle phase.
