RESUMEN

Despite the association of neighborhood quality with poorer adult health, limited research has explored the association between neighborhood disadvantage, e.g. Area Deprivation Index (ADI), and older Black adults' health, prospectively. This observational study examined the association between ADI and changes in longitudinal physical health within older Black adults. The analytic sample (n = 317) included data from waves 1 & 2 of the Baltimore Study of Black Aging: Patterns of Cognitive Aging (BSBA-PCA). Study variables included the Area Deprivation Index (ADI), objective (e.g. average heart rate) and subjective (e.g. activities of daily living) measures of physical health. Multiple linear regression models were conducted controlling for sociodemographic and social support characteristics. Participants living in more disadvantaged neighborhoods, based on national and state ADIs, were more likely to have a decreasing heart rate even after adjusting for covariates. Likewise, participants reporting increasing levels of ADL difficulty were living in a neighborhood with greater disadvantage based on national and state ADI rankings. Significant social support received and ADI (national and state) interactions were observed for average heart rate. The findings suggest that research on the effect of neighborhood quality and social support can enhance our understanding of its impact on older Black adults' health prospectively.

RESUMEN

INTRODUCTION: Compared with other racial/ethnic groups, African Americans have higher rates of chronic conditions and suffer a disproportionate burden of disability. We aimed to examine the effects of social support on physical functioning among older African Americans. METHODS: We analyzed a sample of 448 urban, community-dwelling, older African Americans (aged 48-98 years) from the Baltimore Study of Black Aging. Baseline physical functioning was collected between 2006 and 2008 (wave 1), and change in physical functioning was collected between 2009 and 2011 (wave 2), physical functioning was assessed by self-reported limitations in 7 activities of daily living-eating, dressing, grooming, walking, bathing, using the toilet, and transferring in and out of bed-using a binary variable to indicate whether the individual had difficulty performing each specific activity. Social support was measured by how frequently participants provided/received goods and services, financial assistance, transportation, companionship, advice, or encouragement (never [0], rarely [1], sometimes [2], frequently [3]). Negative binomial regression models were used to test the effects of social support given, received, and a ratio (support received/support given) on physical functioning for those who improved and those who declined in physical functioning. RESULTS: Participants reported physical functioning at wave 1 (1.24, standard deviation [SD] = 1.98) and at wave 2 (0.34, SD = 0.83). Average social support given was 7.49 (SD = 3.26), and average social support received was 7.81 (SD = 3.17). Those who improved in physical function gave less social support and had lower social support ratios; social support received had no effect. Those who remained stable or declined in physical function gave more social support; neither social support received nor social ratio had an effect. CONCLUSION: Social support given and social support received as well as the ratio should be considered when seeking to understand how physical functioning changes over time among older African Americans.

RESUMEN

Older African Americans consistently report diminished capacities to perform activities of daily living (ADL) compared with other racial groups. The extent to which bodily pain is related to declining abilities to perform ADL/ADL disability in African Americans remains unclear, as does whether this relationship exists to the same degree in African American men and women. For nurses to provide optimal care for older African Americans, a better understanding of the relationship between bodily pain and ADL disability and how it may differ by sex is needed. The aim of this study was to examine whether pain, age, education, income, marital status and/or comorbid conditions were associated with ADL disabilities in older African American women and men. This was a cross-sectional descriptive study. The sample included 598 participants (446 women, 152 men) from the first wave of the Baltimore Study on Black Aging. African American women (odds ratio [OR] = 4.06; 95% confidence interval [CI] 2.63-6.26) and African American men (OR = 6.44; 95% CI = 2.84-14.57) who reported bodily pain had greater ADL disability than those who did not report bodily pain. Having two or more comorbid conditions also was significantly associated with ADL disability in African American women (OR = 3.95; 95% CI: 2.09-7.47). Further work is needed to understand pain differences between older African American women and men to develop interventions that can be tailored to meet the individual pain needs of both groups.

RESUMEN

OBJECTIVE: Vascular burden has been linked to future depression and cognitive change in predominately European American samples. This study investigated these relationships in older African Americans. METHODS: To examine the connection between vascular risk factors, depression, and cognitive change, this study utilized data from 435 older African Americans. Specifically, the study examined the link between vascular risk at baseline with depression and cognitive functioning at a 2.5-year follow-up visit. RESULTS: High baseline vascular risk was associated with increased odds of future depression while controlling for age and current depression. A series of path analyses demonstrated links between baseline vascular risk, increases in depression, and decreases in processing speed. CONCLUSIONS: These findings suggest that African Americans with greater vascular burden are at greater risk for depression and cognitive change.

RESUMEN

BACKGROUND: Insurance benefit design influences whether individuals with diabetes who require a continuous glucose monitor (CGM) to provide real-time feedback on their blood glucose levels can obtain the CGM device from either a pharmacy or a durable medical equipment supplier. The impact of the acquisition channel on device adherence and health care costs has not been systematically evaluated. OBJECTIVE: This study aims to compare the adherence rates for patients new to CGM therapy and the costs of care for individuals who obtained CGM devices from a pharmacy versus acquisition through a durable medical equipment supplier using retrospective claims analysis. METHODS: Using the Mariner commercial claims database, individuals aged >18 years with documented diabetes and an initial CGM claim during the first quarter of 2021 (2021 Q1, index date) were identified. Patients had to maintain uninterrupted enrollment for a duration of 15 months but file no CGM claim during the 6 months preceding the index date. We used direct matching to establish comparable pharmacy and durable medical equipment cohorts. Outcomes included quarterly adherence, reinitiation, and costs for the period from 2021 Q1 to the third quarter of 2022 (2022 Q3). Between-cohort differences in adherence rates and reinitiation rates were analyzed using z tests, and cost differences were analyzed using 2-tailed t tests. RESULTS: Direct matching was used to establish comparable pharmacy and durable medical equipment cohorts. A total of 2356 patients were identified, with 1178 in the pharmacy cohort and 1178 in the durable medical equipment cohorts. Although adherence declined over time in both cohorts, the durable medical equipment cohort exhibited significantly superior adherence compared to the pharmacy cohort at 6 months (pharmacy n=615, 52% and durable medical equipment n=761, 65%; P<.001), 9 months (pharmacy n=579, 49% and durable medical equipment cohorts n=714, 61%; P<.001), and 12 months (pharmacy 48% and durable medical equipment n=714, 59%; P<.001). Mean annual total medical costs for adherent patients in the pharmacy cohort were 53% higher than the durable medical equipment cohort (pharmacy US $10,635 and durable medical equipment US $6967; P<.001). In nonadherent patients, the durable medical equipment cohort exhibited a significantly higher rate of therapy reinitiation during the period compared to the pharmacy cohort (pharmacy 61/613, 10% and durable medical equipment 108/485, 22%; P<.001). CONCLUSIONS: The results from this real-world claims analysis demonstrate that, in a matched set, individuals who received their CGM through a durable medical equipment supplier were more adherent to their device. For individuals who experienced a lapse in therapy, those whose supplies were provided through the durable medical equipment channel were more likely to resume use after an interruption than those who received their supplies from a pharmacy. In the matched cohort analysis, those who received their CGM equipment through a durable medical equipment supplier demonstrated a lower total cost of care.

RESUMEN

OBJECTIVES: This study explored the association between place-based characteristics (e.g., neighborhood socioeconomic deprivation) and physical health within older Black adults, a critical gap in the literature as identified by the National Institute on Minority Health and Health Disparities. METHODS: The sample was from Wave 1 data of Baltimore Study of Black Aging: Patterns of Cognitive Aging (N = 450; Mage = 68.34). Variables included the area deprivation index (ADI), objective (e.g., average blood pressure) and subjective (e.g., self-rated health) measures of physical health. Multiple linear regression models were conducted controlling for key sociodemographic characteristics. RESULTS: Participants reporting better self-rated health and less likely to need help with activities of daily living were significantly more likely to be living in more disadvantaged neighborhoods based on national and state ADI, respectively, even after adjusting for covariates. A significant age and ADI interaction revealed better self-rated health was associated with a more disadvantaged neighborhood particularly for individuals ≤66 years. There was no significant association between ADI and objective physical health measures. DISCUSSION: The findings suggest that national- and state-level place-based characteristics should be considered along with individual-level factors, which can enrich the scientific understanding of how neighborhood characteristics relate to varying health indicators among older Black adults.

RESUMEN

UNLABELLED: BACKGROUND/STUDY CONTEXT: Everyday cognition represents the ability to solve problems within domains that are representative of issues faced by adults on a daily basis. The current study examined individual differences in everyday cognitive ability among aging Black/African American adults. METHODS: Demographic data on age, gender, education, physical functioning, chronic illnesses, self-reported health, and depression were collected from 248 African American adults (mean age = 67.8 years, standard deviation = 8.47 years). A multiple indicators, multiple causes (MIMIC) modeling approach was used to examine the associations of individual characteristics with latent everyday cognitive ability and composite score indicators. RESULTS: Age, depressive symptoms, and number of chronic illnesses were negatively related to latent everyday cognition. The individual characteristics of age, depressive symptoms, self-rated health, and education were directly associated with composite indicators of latent everyday cognition. This suggests that within this sample of older Black/African American adults that certain composite scores (i.e., telephone use, food preparation, and finances) may be particularly sensitive to these individual characteristics. CONCLUSION: These results identify specific sources of variability in everyday cognitive ability among aging Blacks/African Americans. These individual differences should be accounted for when studying everyday cognition among Blacks/African Americans and when comparing the everyday cognitive ability of Blacks/African Americans with other groups.

RESUMEN

UNLABELLED: BACKGROUND/STUDY CONTEXT: The current study examined the relationship between intellectual control and cognition and related the results to everyday problem solving in a mixed ethnicity sample of 35% African American and 65% Caucasian elders. METHODS: Participants completed the Personality in Intellectual Aging Contexts Inventory (PIC; Lachman et al., 1982 , Journal of Research in Personality, 16, 485-501), Everyday Cognition Battery (ECB; Allaire & Marsiske, 1999 , Psychology & Aging, 14, 627-644; 2002 , Psychology & Aging, 17, 101-115), and a battery of basic cognitive ability tests assessing memory, inductive reasoning, and verbal meaning. RESULTS: Results indicated that African Americans had significantly lower intellectual control beliefs relative to Caucasian older adults. Regression models suggested that relationship between control beliefs and cognition was moderated by education and race. Decomposing the interactions with simple slope analysis revealed that across cognitive abilities, better cognitive performance was related to higher control beliefs in African Americans with at least 13 years of education. A similar relationship was also found in Caucasian elders with lower education. CONCLUSION: African American elders' reaching a higher level of education may provide a basis for which individual differences in intellectual control beliefs are activated and thereby more strongly associated with cognitive performance.

RESUMEN

BACKGROUND: This systematic literature review examines the current immune checkpoint inhibitors treatment paradigms, treatment gaps and unmet needs for treating SCLC with respect to efficacy, safety, health related quality of life (HRQoL) and cost-effectiveness. METHODS: A search strategy was developed and executed using the National Library of Medicine bibliographic database (PubMed), Cochrane Library, Embase and Google Scholar. Data regarding efficacy, safety, cost-effectiveness and HRQoL were extracted and entered in a data extraction sheet created a priori. RESULTS: A total of 4961 patients were comprised in all the 12 studies combined. All the studies focus on extensive stage SCLC (ES-SCLC) and not limited stage SCLC (LS-SCLC). All studies used an ICI as the intervention arm and chemotherapy as the control arm. A statistically significant increase in overall survival (OS) and progression free survival (PFS) was observed when ICIs were added to chemotherapy, especially atezolizumab and durvalumab. ICIs in SCLC resulted in immune-related toxicities that have been well-documented in prior immunotherapy trials; their addition to cytotoxic chemotherapy did not worsen chemotherapy-related toxicities. Out of 12 studies, only 3 (25%) included measures to assess the impact of immunotherapy on SCLC patients' HRQoL. Although domain level scores were limited, the addition of ICIs did not seem to worsen symptoms. Two studies conducted a cost-effectiveness analysis of the combination of atezolizumab plus chemotherapy vs. chemotherapy. The addition of atezolizumab to chemotherapy was not found to be cost-effective in either study. CONCLUSION: Combining ICIs with chemotherapy enhanced OS and PFS as well as not worsening HRQoL. Among all ICIs, PD-L1 inhibitors showed better effectiveness. Future studies should focus on real-world settings and more clinical trials using ICIs for not only ES-SCLC but also LS-SCLC.

RESUMEN

OBJECTIVES: This study examined engagement levels across various domains of leisure activities in community-dwelling Black adults (age range = 50-80 years) and variability in daily leisure activity engagement and positive affect (PA; positive emotions or mood) and negative affect (NA; negative emotions or mood). Additionally, we explored whether PA and NA were associated with leisure activity engagement and whether these associations varied by sociodemographics. METHODS: Fifty adults (78% women; mean education = 11.62 years, standard deviation = 2.4) reported affect and leisure activity engagement over 8 occasions (2-3 weeks). RESULTS: Participants averaged 3 leisure activities/day with more engagement in watching television (news), walking, reading, and visiting others. Multilevel models identified significant within-person variation across domains of leisure activity engagement. A significant main effect was observed between daily NA and reduced social activity engagement. A significant interaction between NA and education was further illustrated on those occasions when NA was higher than usual, social and total leisure activity engagement tended to be lower, particularly for adults with ≤10 years of education. A significant interaction between NA and education was observed for entertainment activities. However, results indicated adults with ≥14 years of education, and a mean NA above the sample average, tended to engage in more entertainment activities. Finally, a significant interaction between PA and age was observed indicating adults aged ≥73 had a greater social engagement, particularly when daily PA was heightened. DISCUSSION: Results demonstrate within-person changes in the types of leisure engagement among Black adults. Potential factors related to these changes may result from interconnections between affect and demographic factors (age and education).

RESUMEN

The present study examined age differences in the within-person daily associations of basic cognition, everyday cognition, and busyness with forgetting to take medication. The authors extend previous interindividual difference findings by conducting a daily diary study of a baseline assessment and 8 consecutive days of 40 older adults (age = 60-89 years, M = 74.86) and 31 younger adults (age = 18-20 years, M = 18.30) where basic cognition, everyday cognition, busyness, and forgetting medication were assessed each day and entered simultaneously into one model. Results from a logistic multilevel model indicated that performance on Letter Series was beneficial for both age groups, but the role of fluctuations in busyness on forgetting to take medications was opposite for younger and older adults. Younger adults remembered to take their medication the most on days when they had high everyday cognition and were busier. Older adults remembered to take their medication the most on days when they had high everyday cognition but were less busy. These findings highlight the importance of contextual variation in busyness in relation to daily medication adherence for younger and older adults.

RESUMEN

The current analysis examined (a) if measures of psychological well-being predict subjective memory, and (b) if subjective memory is consistent with actual memory. Five hundred seventy-nine older African Americans from the Baltimore Study of Black Aging completed measures assessing subjective memory, depressive symptomatology, perceived stress, locus of control, and verbal and working memory. Higher levels of perceived stress and greater externalized locus of control predicted poorer subjective memory, but subjective memory did not predict objective verbal or working memory. Results suggest that subjective memory is influenced by aspects of psychological well-being but is unrelated to objective memory in older African Americans.

RESUMEN

INTRODUCTION: Esophageal cancer (EC) makes up 3.2% of all cancers but ranks sixth among cancer-related deaths worldwide. This real-world analysis determined the use of PD-1/PD-L1 (PD[L]1) inhibitors in EC patients after receiving first-line therapy. METHODS: Newly diagnosed EC patients initiating first-line treatment were identified in the IBM MarketScan administrative claims databases during the study period (1 May 2015 to 31 October 2020) using ICD-9/ICD-10 codes. Patients were assigned to either the chemotherapy only, radiation only, chemotherapy plus radiation (chemoradiation), or esophageal transhiatal/transthoracic surgery cohorts. RESULTS: 7276 EC patients started first-line therapy (chemotherapy only = 2502, radiation only = 3355, chemoradiation = 1180, surgery = 239). The average age at diagnosis was 62 years and 23% were female. The median time from start of first-line therapy to utilization of a PD(L)1 inhibitor was 259 days. Pembrolizumab (72%) was the most frequently used PD(L)1 inhibitor across the three cohorts, followed by nivolumab (25%). Furthermore, the number of patients receiving a PD(L)1 inhibitor increased each year with the majority (73%) of use occurring between 2018 and 2020. DISCUSSION: Findings from this real-world study suggest that PD(L)1 inhibitors are increasingly used after first-line therapies in EC, especially among patients initially receiving chemotherapy only. New immunological therapies such as PD(L)1 inhibitors hold great promise for patients with solid tumors. A clearer understanding of their real-world utilization is critical.

RESUMEN

OBJECTIVES: The theory of selective survival suggests that possibly around 70-75 years of age, Blacks may display substantive changes in their pattern of cognitive decline. This study examined the age-graded pattern of cognitive decline within older Blacks by describing a trend that characterizes differences in the change of cognitive decline from ages 51.5 to 95.5, and hypothesized that this age-graded pattern is nonlinear. METHOD: Utilizing 2 waves of longitudinal data from the Baltimore Study of Black Aging, this study used multilevel modeling to test whether the interaction between age and the 3-year study period (time between waves) had a positive effect on changes in inductive reasoning, declarative memory, working memory, and perceptual speed. RESULTS: A significant positive interaction between age and wave was found for inductive reasoning, demonstrating an age-grade pattern of change/decline in cognitive pattern for Blacks aged 51.5-95.4. Simple slope probing via the Johnson-Neyman Technique suggested that Black adults ~64 years and younger experienced significant decline in inductive reasoning across study time, whereas for those older than 63.71, the decline was nonsignificant. No significant age-wave interactions were found for declarative memory, working memory, or perceptual speed. DISCUSSION: Findings suggest a selective survival effect for inductive reasoning ability among Blacks. With decline evident so early, common cognitive intervention programs targeting adults 65+ may come too late for Blacks, signifying the importance and urgency for early health interventions and public policy designed to promote cognitive reserve.

RESUMEN

OBJECTIVES: To examine the frequency of Mild Cognitive Impairment (MCI) in African American older adults. The study also plans to explore the specific cognitive domains of impairment as well as whether there are differences in demographics, health, and cognitive performance between MCI and normal participants. DESIGN: Cross-sectional. SETTING: Independent-living sample of urban dwelling elders in Baltimore, Maryland. PARTICIPANTS: The sample consisted of 554 subjects ranging in age from 50 to 95 (Mean = 68.79 +/- 9.60). MEASUREMENTS: Socio-demographics and health were assessed. Several cognitive measures were administered to assess inductive reasoning, declarative memory, perceptual speed, working memory, executive functioning, language and global cognitive functioning. RESULTS: Approximately 22% of participants were considered MCI (i.e. 18% non-amnestic vs. 4% amnestic). A majority of the non-amnestic MCI participants had impairment in one cognitive domain, particularly language and executive function. Individuals classified as non-amnestic MCI were significantly older and had more years of education than normal individuals. The MCI groups were not significantly different than cognitively normal individuals on health factors. Individuals classified as MCI performed significantly worse on global cognitive measures as well as across specific cognitive domains than cognitively normal individuals. CONCLUSION: This study demonstrates that impairment in a non-memory domain may be an early indicator of cognitive impairment, particularly among African Americans.

RESUMEN

This study examined the fluid-crystallized distinction of cognitive abilities in African Americans. We analyzed the factorial invariance of a battery of cognitive ability measures in a sample of 197 community-dwelling African American elders. Specifically, factorial invariance was tested in groups of African American elders differing in age (50-61 years, 62-79 years) and education (low, high). Using a partial invariance approach, if non-invariance was found between two groups, we explored the specific model parameters that contributed to the overall lack of invariance. The results indicated that the factor structure was confirmed in the sample as a whole. Evidence of strict invariance was found between age groups. However, a lack of invariance of specific factor loadings, intercepts, and uniqueness terms was found between education groups. The importance of highlighting idiosyncrasies in cognitive performance among African Americans is shown using a within group variation approach.

RESUMEN

OBJECTIVES: The present study examined potential sources of intra- and inter-individual differences in older adults' control beliefs using a micro-longitudinal design. METHOD: Older adults (n = 205) ranging in age from 60 to 94 (M = 72.70, SD = 6.72) completed 8 in-person testing sessions within 3 weeks which included assessments of control beliefs (Locus of Control and Perceived Competence), physical health (physical symptoms and sleep self-efficacy), stressors, emotional well-being (Positive Affect and Negative Affect), and cognition (basic cognition tests, everyday cognition, and memory failures). RESULTS: Multilevel models indicated that on days when older adults had higher sleep self-efficacy, more positive affect, and less negative affect, they also had more internal locus of control and higher perceived competence. Having stressors on the previous occasion was associated with lower internal locus of control on the subsequent occasion. Physical symptoms, everyday cognition, and memory failures could be predictive of locus of control for some older adults. DISCUSSION: Our findings showed the differentiated antecedents of locus of control and perceived competence, the unique role of sleep self-efficacy, positive affect, and negative affect in understanding antecedents of both, as well as the need to study well-being and cognition antecedents of control beliefs in future studies.

RESUMEN

OBJECTIVES: Identify mechanisms associated with video-game-related gains in cognitive functioning. METHOD: Seventy-nine older adults (Mean age = 72.72, SD = 7.16) participated in a pretest-posttest intervention study. A video game that required four cognitive abilities was developed. The game had two modes: (1) variable priority training (VPT) and (2) single priority training (SPT). After a pretest session, participants completed a battery of cognitive tasks and 'were randomly assigned to either the VPT (n = 42) or the SPT mode (n = 37) for an average of 15.94 (SD = 2.15) one-hour game play sessions. Post-testing was administrated within one week after completion of training. RESULTS: Time (pretest/posttest) by game mode (VPT/SPT) interactions were examined using Multivariate Repeated Measure ANOVAs. No significant multivariate training effects were observed. DISCUSSION: Results suggest that VPT may not be the underlying mechanism responsible for video-game-related gains in cognition. Our results also cast doubts on whether playing video games could lead to cognitive enhancements in older adults.

RESUMEN

The structure and organization of cognitive abilities has been examined across the life span. The current analysis had three specific aims: (1) test the factor structure of a broad cognitive ability battery across three age groups; (2) examine differences in the pattern of factor covariation across age groups; and (3) examine the pattern of factor mean differences across age groups. A sample of 512 older African Americans (mean age = 66.6 years, 25.4% male) from the Baltimore Study of Black Aging was administered a battery of cognitive tests assessing the domains of perceptual speed, verbal memory, inductive reasoning, vocabulary, and working memory. Factor models were estimated separately in middle-age adults (50-59 years, n = 107), young-old adults (60-69 years, n = 198), and old-old adults (70-79 years, n = 207). There was loading invariance across the three age groups that suggests that the selected tests measured cognition similarly across age. There was no evidence of dedifferentiation across increasingly older age groups. Factor mean differences were observed with the middle-age group having significantly higher factor means than the young-old and old-old groups; however, there was only one factor mean difference between the young-old and the old-old groups. The results suggest that a pattern of dedifferentiation of cognitive abilities does not exist within this sample of older African Americans and that the 60-69 year age range may be a critical period for cognitive decline in this population.

RESUMEN

Objective: The purpose of the current study is to examine the association between subjective memory complaints and sleep (quantity and quality) in African American older adults. Method: Participants from the Baltimore Study of Black Aging (BSBA; n = 351; mean age = 71.99) completed a self-report sleep scale, subjective memory complaint scale, global cognitive status measure, and demographic questionnaire. Results: Worse overall sleep quality was significantly associated with subjective reports of difficulty recalling the placement of objects, recalling specific facts from reading materials, and worse memory currently compared to the past. Specific sleep parameters (e.g., longer sleep latency and shorter sleep duration) were associated with negative appraisals of participants' ability to do specific tasks involving memory (e.g., difficulty recalling placement of objects). Participants classified as poor sleepers (Pittsburgh Sleep Quality Index [PSQI] total score > 5) were more likely to report worse memory now compared to the past than participants classified as good sleepers (PSQI total score ≤ 5). Conclusions: Evaluation of sleep may be warranted when older adults, particularly African Americans, communicate concerns regarding their memory. Insufficient sleep may be a useful marker of acute daytime dysfunction and, perhaps, cognitive decline. Given memory problems are the hallmark of dementia, our findings support further evaluation of whether poor sleep can aid in the diagnosis of cognitive impairment.
