Informed by the biopsychosocial framework, our study uses the Chinese Longitudinal Healthy Longevity Survey (CLHLS) dataset to examine cognitive function trajectories among the oldest-old (80+). Employing K-means clustering, we identified two latent groups: High Stability (HS) and Low Stability (LS). The HS group maintained satisfactory cognitive function, while the LS group exhibited consistently low function. Lasso regression revealed predictive factors, including socioeconomic status, biological conditions, mental health, lifestyle, psychological, and behavioral factors. This data-driven approach sheds light on cognitive aging patterns and informs policies for healthy aging. Our study pioneers non-parametric machine learning methods in this context.

Comorbid dementia complicates cancer therapy decision-making in older adults. We aimed to synthesize the recent literature (<5 years) on the challenges associated with cancer therapy decision-making among older people living with dementia (PLWD) and their caregivers. Of the 20,763 references, 8767 had their title and abstract screened, and eight met the inclusion criteria. Six studies were qualitative, one study employed mixed methods, and one study was quasi-experimental. Most studies were conducted in the UK (89%) and reported homogeneity in race and geography. Breast (56%) and prostate (45%) were the most frequent reported cancers. Five studies (56%) reported multiple types of dementia, with two (22%) indicating stages. The studies indicated that communication between patients, caregivers, and clinical teams might alleviate stress caused by worsening health prospects and potential ethical concerns. Information from this review can lead to better-informed, patient-centered treatment decision processes among older PLWD and cancer, their caregivers, and clinicians. [ABSTRACT FROM AUTHOR]

In this study, the parametric analysis was conducted on different designs of the free-suspended ceiling radiant cooling panel (CRCP) and panel area to improve its cooling performance. A three-dimensional CFD simulation model was developed to investigate the cooling capacity and heat transfer coefficient of the CRCPs. Four parameters were used to be the design parameters: the panel length L, the panel curvature radius r, the void distance between each panel or panel segment d, and the panel coverage area Ac. The L/r ratio was also considered, representing the curvature of panel. Twenty-three designs were compared under seven different cooling load conditions. The cooling capacity curve of each design was given as the regression curve of the cooling capacity and temperature difference between air and panel surface. The results show that the CRCPs with curved shape and void have better cooling performance compared to the reference results. The cooling capacity and heat transfer coefficient increase with increasing curvature radius and coverage area and decreasing the panel length. Additionally, the nominal cooling capacity is the largest when L/r is 0.5. The distance between adjacent panels or panel segments and the panel to the wall is most significant in enhancing cooling capacity.

Informed by Donabedian's quality-of-care framework, this study aims to examine elderly clients' service satisfaction and service recommendation for community-based meal services in Shanghai. We analyzed secondary survey data from randomly sampled elderly clients of a community-based meal service in the old Jing'an District in Shanghai (N= 690). Quality of food and caregivers' attitudes were key to respondents' service recommendation while tidiness of tableware and interactions with caregivers were positively related to their service satisfaction. Overlaps and differences between structure and process factors are discussed. We also provide tailored policy recommendations. [ABSTRACT FROM AUTHOR]

Objective: This article examines the relative importance of cancer-related and noncancer illness factors as they predict the health quality of life among older adult, long-term cancer survivors. Specifically, it examines the effects that continuing cancer symptoms and comorbidities have on functional difficulties and how they in turn affect perceptions of disability and self-rated health. Method: Data from an National Cancer Institute (NCI)-funded, tumor registry–based 10-year study of 321 older adult (age 60+), long-term (5+years post diagnosis) survivors of breast colorectal and prostate cancer are examined using regression analyses. Results: The analyses documented the independent effects of both cancer-related and age-related health factors as they contribute to explaining functional difficulties, perceptions of disability and self-rated health. Gender and racial differences in health quality of life were also identified. Discussion: The findings suggest that geriatricians, geriatric nurses, and clinical gerontologists who work with cancer survivorsneed to be aware of the ways in which both cancer and noncancer illness factors work together in producing threats to health quality of life through the extent and nature of functional impairments.

The purpose of this study is to explore direct carers’ work experience and formal caring relationships with older adults in a community-based eldercare program in Shanghai. Existing evidence has primarily focused on direct carers’ work experience in residential care settings. However, direct carers’ experiences of caring older adults in the community also deserve exploration. This qualitative study purposively sampled direct carers who worked in government-sponsored programs. Carers participated in semi-structured, in-depth interviews (N = 37). Results reveal that despite occasional frustration, direct carers undertook demanding workloads and fostered strong emotional attachments with older adult clients. “Karma” was a critical cultural factor pertaining to their work ethic and motivated their care provision to benefit their future elderly selves. This study recognizes the cultural aspects of caring relationships that contribute to the quality of care of the community-based older adults in urban China. [ABSTRACT FROM AUTHOR]

This study assesses whether prior marital quality moderates the impact of divorce or widowhood on subsequent depression. Poor marital quality may buffer depression associated with divorce/widowhood; conversely, the effect of divorce/widowhood on depression could be exacerbated by previous marital quality. Three waves from the National Survey of Families and Households based on respondents, ages 50 and older, (N = 2,570) included eight marital quality measures. We find limited evidence suggesting higher marital quality elevates, while lower marital quality decreases, depression after divorce. No moderating effects were found for widowhood. Additionally, health condition is more important than current marital status for elders’ well-being after divorce or widowhood. Heterogeneity in the context of the marriage before divorce should be considered when examining marital termination effects on elders’ depression. [ABSTRACT FROM PUBLISHER]
