A National Typology of Health Service Regulation in Assisted Living.

BACKGROUND AND OBJECTIVES: State-regulating agencies use 350 different licenses and certifications to govern assisted living (AL), resulting in significant variation in regulations governing health services, the scope of practice, and capacity. This lack of standardization makes it difficult to compare and contrast AL operations and residents' outcomes across similarly regulated communities. RESEARCH DESIGN AND METHODS: We used qualitative and quantitative methods to empirically develop and describe a typology of state AL regulations that captures inter- and intrastate variation. Based on the rules governing health services, we created regulatory specificity scores for 5 thematic dimensions: medication administration, third-party care, skilled nursing, medication review, and licensed nurse staffing. With these scores, we conducted a K-means cluster analysis to identify groups of AL license types. To differentiate the regulatory types, we calculated standardized mean differences across structure, process, outcome, and resident characteristics of the AL communities licensed under each type. RESULTS: We identified 6 types of AL differentiated by the regulatory provisions governing health services: Housing, Holistic, Hybrid, Hospitality, Healthcare, and Health Support. The types align with previous work and reflect tangible differences in resident characteristics, health service structures, processes, and outcomes. DISCUSSION AND IMPLICATIONS: This typology effectively captures differences across regulated dimensions and can inform and support quality of care. Researchers, policy-makers, and consumers may benefit from using this typology and acknowledging these differences in AL licensure when designing research studies, developing policies, and selecting an AL community.

Hydroxycinnamic Acid Amide Dimers from Goji Berry and Their Potential Anti-AD Activity.

Three undescribed hydroxycinnamic acid amide dimers 1-3 were isolated and identified from an extract of Goji berry. Their molecular structures were elucidated based on NMR, MS, and IR spectra analysis. Compounds 1-3 were hydroxycinnamic acid amide dimers, which possess a cyclic butane moiety formed by head-to-head connection. These compounds at 25 µM showed the disaggregation potency on the copper-mediated Aß1-42 aggregation ranging from 27.3±3.2 to 31.0±2.9 %. This study provides new information on the antiaging traditional usage of goji berry.
