Background: The intersection of race/ethnicity with disability is a critical dimension of mental health outcomes in later ages that remains under-investigated.

Objective: We examined the role of race-ethnicity in moderating the associations between functional disabilities and subsequent depression among Americans 51 and older and stratified into the two age-groups of midlife (51-64) and older adults (≥65).

Methods: Using a nationally representative sample of community-dwelling Americans (≥51; n = 7475) in the 2016-2018 Health and Retirement Study, we conducted bivariate and multivariable regression analyses.

Guided by the Rowe and Kahn model, the current study examined the longitudinal association of objective and subjective components of successful aging (SA) with individuals' life satisfaction and level of optimism across adulthood aiming to validate the related scanty existing research. Data were from waves 2 and 3 (2004-14) of the Midlife in the United States (MIDUS) study. Using structural equation modeling, we examined ( = 2,040) whether subjective life satisfaction (wave 2) has any effect on a composite measure of SA (wave 3) while controlling for baseline sociodemographic and health factors.

Complaints represent an important metric for assessing the quality of nursing home (NH) care. Using the Automated Survey Processing Environment (ASPEN) Complaints/Incidents Tracking System dataset (2017), we examined the relationships between zero-deficiency complaints (ZDCs) and zero-deficiency substantiated complaints (ZDSCs) and the proportion of residents with dementia. NHs ( = 15,339) were separated into three groups-proportion of residents with dementia in the top, two middle, and the bottom quartiles.

Assisted Living (AL) residents are embedded in "care convoys" comprised of a dynamic network of formal and informal care partners. Using the model-a multi-level framework connecting care convoy properties to resident outcomes-we examined healthcare management and communication between convoy members. We recommend strategies to engage primary care in supporting collaboration, communication, and consensus-building for older adults and their convoys.

Reactive oxygen species (ROS) plays important role to maintain homeostasis in living bodies. Here we have studied interaction of ROS generated from hydrogen peroxide (HO) with a well-known spectroscopic probe Rose Bengal (RB) encapsulated in nanoscopic sodium dodecyl sulphate (SDS) micelles in aqueous medium and entrapped in microscopic nylon 66 solid matrix generated using electrospinning technique. A detailed spectroscopic characterization of ROS with SDS encapsulated RB (RB-SDS) shows efficient interaction compared to that in bulk medium.

Background: Cognitive function is an important component of healthy ageing. However, it is unclear whether relaxation/meditation practices provide cognitive benefits, particularly in midlife and early late life. Meditative practices are associated with higher self-esteem, and self-esteem serves as a general protective factor for many health outcomes.

Nursing home (NH) residents' capacity to communicate deteriorates with dementia. Consequently, NHs with high proportions of people living with dementia (PLWD) may receive fewer resident complaints, and/or investigating complaints may be challenging. We assessed NHs' proportion of PLWD in relation to total and substantiated complaints.

Objectives: The current study examined whether informal caregivers performed worse, better, or similar to non-caregivers on cognitive tests of executive functioning and episodic memory over 10 years. Data were from waves 2 (2003-04) and 3 (2013-14) of the Midlife in the United States (MIDUS) study ( = 2086). Multiple linear regression models examined whether caregiving at both waves 2 and 3 predicted better cognitive functioning at wave 3, than caregiving at only one time point or no caregiving (reference) while controlling for baseline covariates (i.

Informal caregiving has been associated with higher stress and lower levels of subjective well-being. Mind-body practices including yoga, tai chi, and Pilates also incorporate stress reducing activities. The current study aimed to examine the association between mind-body practice and subjective well-being among informal family caregivers.

A person-centered approach to care shifts the mind-set of care partners from a traditional medical model to a social model in managing chronic conditions. Using a qualitative descriptive approach, this study examines the barriers and facilitators to the implementation of person-centered care (PCC) and how the integration of complementary and alternative approaches (CAA) has the potential to improve residents' quality of life in nursing homes (NHs). Findings indicate that NHs offer a wide range of engagement activities, but these activities are not purposefully integrated into a person-centered plan of care.
