Age as a Factor in Diversity, Equity, and Inclusion Initiatives in Higher Education.

Demographic shifts and the growth of diversity, equity, and inclusion (DEI) initiatives are occurring simultaneously on college campuses. This study seeks to understand their intersection by focusing on age in DEI initiatives on college campuses. Findings from six focus groups suggest that age is not given much attention in DEI initiatives. Participants acknowledge the issue of age; but in general, they strive to keep other identities, like race and gender, in the forefront, especially in the face of low resources. While it may be difficult to elevate age in DEI initiatives on campuses, interventions were identified.

Explicating Ageism in the Productive Aging Framework.

This essay argues for a fuller integration of ageism and age discrimination into the productive aging framework. We briefly review the productive aging scholarship and the extent to which ageism has been considered in regards to working, volunteering, education, and caregiving. We suggest that ageism has not been adequately considered, and we identify how it permeates productive engagement in later life. We introduce modifications to the productive aging framework to more directly capture the roles of ageism and age discrimination in activity engagement and the outcomes achieved. We argue for the integration of key concepts from minority stress theory and critical race theory that may yield important insights for an increasingly diverse older population. We conclude with research directions that will guide intervention development to reduce ageism at the societal, organizational and individual level.

Civic Activities and Mental Health in Later Life: The Moderating Role of Generative Concerns.

This study examined the moderating mechanisms of generative concerns (perception of making contributions to others) between generative civic activities and mental health among middle-aged and older adults. A total of 1,109 community-dwelling adults aged over 45 were recruited through an online survey. Generative civic activities (political participation and volunteering), generative concerns (the Loyola Generativity Scale), and two outcomes of mental health (depressive symptoms and mental wellbeing) were measured. Linear regression models and simple slope analyses were used to probe the moderating effects of generative concerns, stratified by age (45-64 years and 65+). Generative activities, but not concerns, were associated with lower depressive symptoms among middle-aged and older adults. Generative concerns and activities were related to better mental wellbeing among middle-aged adults. Generative concerns moderated the associations between civic activities and depressive symptoms. Those with higher generative concerns but lower civic activities had higher depression scores. Conversely, a stronger reduction in depressive symptoms by engaging in civic activities was found only when individuals had greater concerns. No moderating effect was found on mental wellbeing. The positive effect of civic engagement on reducing depressive symptoms depends on generative concerns, particularly among older people and those with greater concerns. Bridging the gap between perceived generative concerns and actual civic actions may improve later-life mental health.

Progressive Cardiac Metabolic Defects Accompany Diastolic and Severe Systolic Dysfunction in Spontaneously Hypertensive Rat Hearts.

Background Cardiac metabolic abnormalities are present in heart failure. Few studies have followed metabolic changes accompanying diastolic and systolic heart failure in the same model. We examined metabolic changes during the development of diastolic and severe systolic dysfunction in spontaneously hypertensive rats (SHR). Methods and Results We serially measured myocardial glucose uptake rates with dynamic 2-[18F] fluoro-2-deoxy-d-glucose positron emission tomography in vivo in 9-, 12-, and 18-month-old SHR and Wistar Kyoto rats. Cardiac magnetic resonance imaging determined systolic function (ejection fraction) and diastolic function (isovolumetric relaxation time) and left ventricular mass in the same rats. Cardiac metabolomics was performed at 12 and 18 months in separate rats. At 12 months, SHR hearts, compared with Wistar Kyoto hearts, demonstrated increased isovolumetric relaxation time and slightly reduced ejection fraction indicating diastolic and mild systolic dysfunction, respectively, and higher (versus 9-month-old SHR decreasing) 2-[18F] fluoro-2-deoxy-d-glucose uptake rates (Ki). At 18 months, only few SHR hearts maintained similar abnormalities as 12-month-old SHR, while most exhibited severe systolic dysfunction, worsening diastolic function, and markedly reduced 2-[18F] fluoro-2-deoxy-d-glucose uptake rates. Left ventricular mass normalized to body weight was elevated in SHR, more pronounced with severe systolic dysfunction. Cardiac metabolite changes differed between SHR hearts at 12 and 18 months, indicating progressive defects in fatty acid, glucose, branched chain amino acid, and ketone body metabolism. Conclusions Diastolic and severe systolic dysfunction in SHR are associated with decreasing cardiac glucose uptake, and progressive abnormalities in metabolite profiles. Whether and which metabolic changes trigger progressive heart failure needs to be established.

Evidence That Binding of Cyclic GMP to the Extracellular Domain of NKA (Sodium-Potassium ATPase) Mediates Natriuresis.

BACKGROUND: Extracellular renal interstitial guanosine cyclic 3',5'-monophosphate (cGMP) inhibits renal proximal tubule (RPT) sodium (Na+) reabsorption via Src (Src family kinase) activation. Through which target extracellular cGMP acts to induce natriuresis is unknown. We hypothesized that cGMP binds to the extracellular α1-subunit of NKA (sodium-potassium ATPase) on RPT basolateral membranes to inhibit Na+ transport similar to ouabain-a cardiotonic steroid. METHODS: Urine Na+ excretion was measured in uninephrectomized 12-week-old female Sprague-Dawley rats that received renal interstitial infusions of vehicle (5% dextrose in water), cGMP (18, 36, and 72 µg/kg per minute; 30 minutes each), or cGMP+rostafuroxin (12 ng/kg per minute) or were subjected to pressure-natriuresis±rostafuroxin infusion. Rostafuroxin is a digitoxigenin derivative that displaces ouabain from NKA. RESULTS: Renal interstitial cGMP and raised renal perfusion pressure induced natriuresis and increased phosphorylated SrcTyr416 and Erk 1/2 (extracellular signal-regulated protein kinase 1/2)Thr202/Tyr204; these responses were abolished with rostafuroxin coinfusion. To assess cGMP binding to NKA, we performed competitive binding studies with isolated rat RPTs using bodipy-ouabain (2 µM)+cGMP (10 µM) or rostafuroxin (10 µM) and 8-biotin-11-cGMP (2 µM)+ouabain (10 µM) or rostafuroxin (10 µM). cGMP or rostafuroxin reduced bodipy-ouabain fluorescence intensity, and ouabain or rostafuroxin reduced 8-biotin-11-cGMP staining. We cross-linked isolated rat RPTs with 4-N3-PET-8-biotin-11-cGMP (2 µM); 8-N3-6-biotin-10-cAMP served as negative control. Precipitation with streptavidin beads followed by immunoblot analysis showed that RPTs after cross-linking with 4-N3-PET-8-biotin-11-cGMP exhibited a significantly stronger signal for NKA than non-cross-linked samples and cross-linked or non-cross-linked 8-N3-6-biotin-10-cAMP RPTs. Ouabain (10 µM) reduced NKA in cross-linked 4-N3-PET-8-biotin-11-cGMP RPTs confirming fluorescence staining. 4-N3-PET-8-biotin-11-cGMP cross-linked samples were separated by SDS gel electrophoresis and slices corresponding to NKA molecular weight excised and processed for mass spectrometry. NKA was the second most abundant protein with 50 unique NKA peptides covering 47% of amino acids in NKA. Molecular modeling demonstrated a potential cGMP docking site in the ouabain-binding pocket of NKA. CONCLUSIONS: cGMP can bind to NKA and thereby mediate natriuresis.

Anti-Ageism for Gerontologists.

We argue that gerontologists are products of our ageist culture and that we both perpetuate ageism and suffer from internalized ageism ourselves. We make ageist comments, deny our own age, fail to teach students to recognize and confront ageism, and use language that otherizes and categorizes older people. Gerontologists are in ideal positions to confront ageism through our scholarly work, teaching, and community engagement. However, we suggest that, despite our deep gerontological knowledge, we do not have enough awareness, knowledge, and skills for taking anti-ageism actions in these arenas of our professional lives. We offer some suggestions for confronting ageism, including self-study, increasing content on ageism in the classroom and beyond, pointing out ageist language and behaviors to colleagues and students, working with diversity, equity and inclusion offices on campus, and giving careful consideration to our research approaches and academic writing. To go forward, we must increase awareness about ageism and gain skills in promoting anti-ageism.

Deaths of Despair and Population Aging in Missouri.

Recent declines in life expectancy in the US, especially for middle-aged White persons, have called attention to mortality from deaths of despair - deaths due to alcohol, drugs, and suicide. Using data from the Centers for Disease Control and the U.S. Census Bureau, this paper examined deaths of despair by race/ethnicity, age, cause of death, birth cohort, and sex in Missouri. We focused on Area Agencies on Aging as geographic units of interest to increase usefulness of our findings to public administrators. Deaths of despair began trending up for all age groups beginning in 2007-2009, with the sharpest increases occurring for Black or African American non-Hispanics beginning in 2013-2015. The most dramatic increases occurred for the population age 50-59 in St. Louis City and Area Agency on Aging regions in southern Missouri. For older adults, considerable variation in rates, trends, and cause of deaths of despair is evident across the state.

Pandemic Pivots for Older Volunteers: Online Tutoring and Pen Pal Programs.

This study explored the experiences of older adult volunteers who pivoted from in-person tutoring to letter writing and online tutoring during the COVID-19 pandemic. Sixty-one older adult volunteers were surveyed in the beginning and end of the school year about their experiences, including their perceived benefits, challenges, and feedback on the pandemic transition. Eleven of the surveyed volunteers participated in focus groups at the end of the school year. Perceived benefits included having a positive impact on a child's life and meaningful engagement during the pandemic, and perceived challenges included difficulty engaging students and lack of control over learning environments. The participants also suggested increasing opportunities for informal interactions with staff and students, technology training, and peer support between volunteers. There was agreement that the remote volunteering experience was not a substitute for in-person tutoring, but it was better than no volunteering at all.

Situating the Pandemic in the Life-Course: Older Adults' Perspectives on the Challenges and Positives of the COVID-19 Pandemic.

Older adults experienced the highest rates of infections and deaths and significant social isolation during the COVID-19 pandemic. While these negative impacts are important to address, the positive outcomes among older adults during the pandemic are equally important. A survey was distributed to adults aged 65 or older living in St. Louis, Missouri from August 2020 through March 2021 to characterize the challenges and positives they found during the pandemic. A total of 103 older adults participated. Compared to previous times in their lives, a majority of participants felt the pandemic had been more disruptive (62%) and more confusing (78%) and a majority were more worried (58%) and more afraid of dying (53%) during the pandemic. The most common positives were increased emotional well-being (23% of responses) and stronger personal connections (20% of responses). This ability to identify positive outcomes of the pandemic demonstrates the resilience of older adults and counters the ageist narrative that dominated the dialogue early in the pandemic, which depicted older adults as weak, vulnerable, and dispensable. As the pandemic evolves, nurturing and leveraging these positives will be key to combatting the cycle of fear and restrictions that the pandemic could bring.

Emergency Department Communication in Persons Living With Dementia and Care Partners: A Scoping Review.

OBJECTIVES: To synthesize published research exploring emergency department (ED) communication strategies and decision-making with persons living with dementia (PLWD) and their care partners as the basis for a multistakeholder consensus conference to prioritize future research. DESIGN: Systematic scoping review. SETTINGS AND PARTICIPANTS: PLWD and their care partners in the ED setting. METHODS: Informed by 2 Patient-Intervention-Comparison-Outcome (PICO) questions, we conducted systematic electronic searches of medical research databases for relevant publications following standardized methodological guidelines. The results were presented to interdisciplinary stakeholders, including dementia researchers, clinicians, PLWD, care partners, and advocacy organizations. The PICO questions included: How does communication differ for PLWD compared with persons without dementia? Are there specific communication strategies that improve the outcomes of ED care? Future research areas were prioritized. RESULTS: From 5451 studies identified for PICO-1, 21 were abstracted. From 2687 studies identified for PICO-2, 3 were abstracted. None of the included studies directly evaluated communication differences between PLWD and other populations, nor the effectiveness of specific communication strategies. General themes emerging from the scoping review included perceptions by PLWD/care partners of rushed ED communication, often exacerbated by inconsistent messages between providers. Care partners consistently reported limited engagement in medical decision-making. In order, the research priorities identified included: (1) Barriers/facilitators of effective communication; (2) valid outcome measures of effective communication; (3) best practices for care partner engagement; (4) defining how individual-, provider-, and system-level factors influence communication; and (5) understanding how each member of ED team can ensure high-quality communication. CONCLUSIONS AND IMPLICATIONS: Research exploring ED communication with PLWD is sparse and does not directly evaluate specific communication strategies. Defining barriers and facilitators of effective communication was the highest-ranked research priority, followed by validating outcome measures associated with improved information exchange.

Neighborhood resources associated with frailty trajectories over time among community-dwelling older adults in China.

BACKGROUND AND OBJECTIVES: Recent research has identified neighborhoods as an important contributor to later-life frailty. However, little is known about how neighborhood resources are associated with frailty trajectories over time, especially in developing countries. This study examines the impact of neighborhood physical and social resources on the trajectories of frailty over time among older people in China. RESEARCH DESIGN AND METHODS: Using the four waves of the China Health and Retirement Longitudinal Study (2011-2018), 5673 respondents aged 60 and above at baseline were included for analyses. Multilevel growth modeling was fitted to estimate the effects of neighborhood resources on frailty trajectories over a 7-year period, controlling for individual-level characteristics. RESULTS: Older Chinese people who lived in neighborhoods with better basic infrastructures and a greater number of voluntary organizations were less frail at baseline. Accessible exercise facilities were associated with a lower initial level of frailty only among rural older adults, while higher community-level socioeconomic status (SES) was associated with a lower initial level of frailty only among urban older adults. Over the 7-year follow-up period, better basic infrastructures and accessible exercise facilities were associated with a slower increase rate of frailty scores among rural residents. DISCUSSION AND IMPLICATIONS: Neighborhood resources are important contributors to the level of frailty among older Chinese people. Our findings of significant urban-rural differences have important implications for designing and implementing infrastructure development and community building programs in rural and urban China.

The Association Between Patterns of Social Engagement and Conversion From Mild Cognitive Impairment to Dementia: Evidence From the Health and Retirement Study.

OBJECTIVES: This study examined the association between patterns of social engagement and conversion from cognitive impairment, no dementia (CIND) to dementia. It also tested whether social engagement is associated with conversion independently from physical and cognitive engagements. METHOD: Data from 2 waves (2010 and 2014) of the Health and Retirement Study (HRS) were used. The sample consisted of 1227 people who had CIND in 2010. To identify the heterogeneity of social engagement, latent class analysis was utilized. Multinomial logistic regression analysis was utilized to investigate the association between patterns of social engagement and probability of conversion to dementia and death or dropout. RESULTS: The result showed that patterns of social engagement that represent higher level and more variety of social engagement were associated with lower probabilities of conversion to dementia in 4 years but not with probabilities of death or dropout. The relationship held after controlling for physical and cognitive engagements. DISCUSSION: Findings implied that promoting social engagement may be protective against developing dementia even for the high-risk group of people with CIND. Future studies should investigate the mechanism behind the relationship between patterns of social engagement and lower probabilities of conversion to dementia.

Perceived Life Expectancy Predicts Time Investment in Productive Aging Activities: An Ecological Momentary Assessment Study.

OBJECTIVES: Despite known benefits of productive aging, it is unclear what explains time allocation in productive activities. We investigated whether productive engagement in older people can be explained by their age, health, socioeconomic status, and perceived life expectancy in Hong Kong. METHODS: We interviewed 390 community-dwelling older persons for their health and perceived life expectancy, followed by a 7-day ecological momentary assessment to record their activities. RESULTS: A total of 366 participants who completed the study (age 75 ± 8.3 years; 79% women) reported an average perceived life expectancy of nearly 10 years. The majority (59%) engaged in productive activities. Estimates of the structural equation model (RMSEA = 0.046) showed that age and health were associated with productive engagement, mediated by perceived life expectancy. DISCUSSION AND IMPLICATIONS: Future efforts in promoting productive aging and related research should include interventions addressing perceived life expectancy, a potentially modifiable factor.

Challenges and opportunities of age diverse universities: Perspectives from admissions and career services.

Universities are experiencing shifts in age distributions of students, with fewer younger students and an increase in the number of people mid-life and beyond seeking education and job training. Thus, there are strong arguments for universities to embrace opportunities to increase age-diversity on campus. This qualitative study explores the challenges, opportunities, and strategies related to university age-diversity from the perspective of Admissions and Career Services staff from one midwestern university. From focus group data, six subthemes were identified as challenges (fitting in; acclimating; stressors; career concerns; return on investment; and ageism/undervaluing age diversity), three subthemes were identified as assets (intentionality; experienced students; and age diverse educational settings) and eight strategies were recommended to better serve an age-diversity student body (support groups; familial supports; social opportunities; job placement; financial aid; targeted outreach; flexibility in learning; and staff support). This article discusses the benefits and challenges of serving older students from the perspective of staff and administrators and provides action steps for universities to promote age-diversity on campus.

The Impact of COVID-19 on Villages: Results from a National Survey.

Villages are consumer-driven organizations that promote aging-in-place. This study documents the effects of the COVID-19 pandemic on Villages and explores variation in response by age of the organization, size of the membership, staffing model, and geographic location. In summer, 2020, we distributed an online survey to executive administrators of 286 Villages in the network. During the pandemic, over 75% of Villages were seen as more or equally valuable for members. Seventy-seven percent of Villages offered virtual socialization events. Most Villages reported a decrease in service requests, given reductions in need for transportation. New services of food and medication delivery were initiated. There is much variation between organizations, but findings suggest that Villages that are older, have more members, and bigger budgets had more capacity and cushion; and although they took a negative hit in income and participation, it was a smaller hit proportionately, compared to younger and smaller Villages. Villages have demonstrated adaptability and creativity. They kept their operations running, provided services, and offered social connection. Vulnerabilities have been exposed: memberships have dropped for many and some members have not been able to participate as before the pandemic. Many lessons learned can help future developments of the Village model.

Renal AT2 Receptors Mediate Natriuresis via Protein Phosphatase PP2A.

BACKGROUND: How signals from activated angiotensin type-2 receptors (AT2R) mediate inhibition of sodium ion (Na+) reabsorption in renal proximal tubule cells is currently unknown. Protein phosphatases including PP2A (protein phosphatase 2A) have been implicated in AT2R signaling in tissues other than kidney. We investigated whether inhibition of protein phosphatase PP2A reduced AT2R-mediated natriuresis and evaluated changes in PP2A activity and localization after renal AT2R activation in normal 4- and 10-week-old control Wistar-Kyoto rats and 4-week-old prehypertensive and 10-week-old hypertensive spontaneously hypertensive rats. METHODS AND RESULTS: In Wistar-Kyoto rats, direct renal interstitial administration of selective AT2R nonpeptide agonist Compound-21 (C-21) increased renal interstitial cyclic GMP (cGMP) levels, urine Na+ excretion, and simultaneously increased PP2A activity ≈2-fold in homogenates of renal cortical tubules. The cyclic GMP and natriuretic responses were abolished by concurrent renal interstitial administration of protein phosphatase inhibitor calyculin A. In renal proximal tubule cells in response to C-21, PP2A subunits A, B55α and C, but not B56γ, were recruited to apical plasma membranes together with AT2Rs. Calyculin A treatment abolished C-21-induced translocation of both AT2R and PP2A regulatory subunit B55α to apical plasma membranes. Immunoprecipitation of AT2R solubilized from renal cortical homogenates demonstrated physical association of AT2R with PP2A A, B55α, and C but not B56γ subunits. In contrast, in spontaneously hypertensive rats, administration of C-21 did not alter urine Na+ excretion or PP2A activity and failed to translocate AT2Rs and PP2A subunits to apical plasma membranes. CONCLUSIONS: In renal proximal tubule cells of Wistar-Kyoto rats, PP2A is activated and PP2A subunits AB55αC are recruited to C-21-activated AT2Rs during induction of natriuresis. This response is defective in prehypertensive and hypertensive spontaneously hypertensive rats, presenting a potential novel therapeutic target for treating renal Na+ retention and hypertension.

Functional outcomes of Tai Chi exercise prescription in women with knee osteoarthritis.

Knee Osteoarthritis (KOA) is the most common type of knee joint injury and also a risk factor for multiple health consequences and is prevalent among older women. The updated clinical guidelines for KOA treatment by the American Rheumatism Association recommend Tai Chi exercise. However, a literature review outlined limitations in Tai Chi intervention implementations. This study aimed to address some of the gaps. This study selected thirty female patients to participate in Tai Chi exercises and undergo relevant tests. The subjects were randomly assigned to Tai Chi or education groups. Independent sample t-tests were conducted to compare the difference in health indicators between the two groups after the intervention. The difference-in-differences (DID) regression was performed to assess the difference in the health outcomes between the two groups at baseline and follow-up and the difference in the differences. After the completion of the intervention, the Tai Chi group reported significantly improved KOA symptoms, physical fitness, and health status indicators than the control group. Specifically, the group differences were significantly larger at the baseline than at the follow-up. Our findings provide compelling evidence of the effects of the innovative Tai Chi exercise prescription specifically designed for KOA patients. The empirical evidence on its effectiveness in alleviating KOA symptoms and improving the overall health of middle-aged and elderly women with KOA suggested that Tai Chi intervention exercise has huge prospects for integration in KOA rehabilitation therapy.

Research priorities for elder abuse screening and intervention: A Geriatric Emergency Care Applied Research (GEAR) network scoping review and consensus statement.

The Geriatric Emergency Care Applied Research (GEAR) Network (1) conducted a scoping review of the current literature on the identification of and interventions to address elder abuse among patients receiving care in emergency departments and (2) used this review to prioritize research questions for knowledge development. Two questions guided the scoping review: What is the effect of universal emergency department screening compared to targeted screening or usual practice on cases of elder abuse identified, safety outcomes, and health care utilization?; and What is the safety, health, legal, and psychosocial impact of emergency department-based interventions vs. usual care for patients experiencing elder abuse? We searched five article databases. Additional material was located through reference lists of identified publications, PsychInfo, and Google Scholar. The results were discussed in a consensus conference; and stakeholders voted to prioritize research questions. No studies were identified that directly addressed the first question regarding assessment strategies, but four instruments used for elder abuse screening in the emergency department were identified. For the second question, we located six articles on interventions for elder abuse in the emergency department; however, none directly addressed the question of comparative effectiveness. Based on these findings, GEAR participants identified five questions as priorities for future research - two related to screening, two related to intervention, and one encompassed both. In sum, research to identify best practices for elder abuse assessment and intervention in emergency departments is still needed. Although there are practical and ethical challenges, rigorous experimental studies are needed.

Older Adults' Attitudes Toward Virtual Volunteering During the COVID-19 Pandemic.

This study explored older adults' technology use patterns and attitudes toward virtual volunteering during the COVID-19 pandemic. A 22-item survey was administered to 229 volunteers in the St. Louis region who tutor children through the Oasis Intergenerational Tutoring program. Although most respondents are familiar with technology and expressed that they are likely to volunteer virtually, their responses varied significantly by age, education, gender, income, and school districts. Some tutors expressed that virtual volunteering may eliminate barriers to in-person volunteering, while others were concerned with establishing a personal connection with students online. These findings suggest that tutors anticipate both benefits and challenges with virtual volunteering and that efforts to engage older adults during the pandemic should factor in prior use of technology and ensure that different subgroups are not marginalized.

Within-couple dissimilarities in functional impairment as determinants of spousal care arrangement among older married couples.

Existing research on spousal care focuses on one spouse receiving care from the other, which fails to address the complexity that is created when both spouses experience some impairments. Our study included situations in which one or both spouses have functional impairments when examining the extent to which spouses from the same couple hold a (dis)similar level of functional impairment and whether such within-couple (dis)similarity has an impact on the spousal care arrangement. A subsample of 1170 older married couples was selected from the 2014 Health and Retirement Study. Descriptive statistics were used for describing the level of each spouse's functional impairment regarding the number of limitations in activities (activities of daily living [ADL]) or instrumental ADL (IADL). Logistic regressions were used to examine whether spousal dissimilarity in functional impairment (dissimilar, similarly low, similarly high) was associated with spousal care arrangement. Within couples with one functionally impaired spouse, the impaired spouse was more likely to receive spousal care when reporting a higher level of ADL/IADL impairment. Within couples with two functionally impaired spouses, the more impaired person was more likely to receive spousal care (without giving back) when spouses reported dissimilar level of IADL impairment; spouses were more likely to report mutual care when they had similarly high levels of IADL impairment. By documenting the role of spousal dissimilarities in functioning for determining spousal care arrangement, our study can inform couple-based interventions that capitalize on each spouse's capabilities and resources.
