Deriving life-course residential histories in brain bank cohorts: A feasibility study.

INTRODUCTION: The exposome is theorized to interact with biological mechanisms to influence risk for Alzheimer's disease but is not well-integrated into existing Alzheimer's Disease Research Center (ADRC) brain bank data collection. METHODS: We apply public data tracing, an iterative, dual abstraction and validation process rooted in rigorous historic archival methods, to develop life-course residential histories for 1254 ADRC decedents. RESULTS: The median percentage of the life course with an address is 78.1% (IQR 24.9); 56.5% of the sample has an address for at least 75% of their life course. Archivists had 89.7% agreement at the address level. This method matched current residential survey methodology 97.4% on average. DISCUSSION: This novel method demonstrates feasibility, reproducibility, and rigor for historic data collection. To our knowledge, this is the first study to show that public data tracing methods for brain bank decedent residential history development can be used to better integrate the social exposome with biobank specimens. HIGHLIGHTS: Public data tracing compares favorably to survey-based residential history. Public data tracing is feasible and reproducible between archivists. Archivists achieved 89.7% agreement at the address level. This method identifies residences for nearly 80% of life-years, on average. This novel method enables brain banks to add social characterizations.

Association between military service and Alzheimer's disease neuropathology at autopsy.

INTRODUCTION: Anti-amyloid therapies are at the forefront of efforts to treat Alzheimer's disease (AD). Identifying amyloid risk factors may aid screening and intervention strategies. While veterans face increased exposure to risk factors, whether they face a greater neuropathologic amyloid burden is not well understood. METHODS: Male decedents donating to two Alzheimer's Disease Research Center (ADRC) brain banks from 1986 to 2018 with categorized neuritic plaque density and neurofibrillary tangles (n = 597) were included. Using generalized ordered logistic regression we modeled each outcome's association with military history adjusting for age and death year. RESULTS: Having served in the military (60% of sample) is associated with post mortem neuritic amyloid plaque (for each comparison of higher to lower C scores OR = 1.26; 95% confidence interval [CI] = 1.06-1.49) and tau pathology (B score OR = 1.10; 95% CI = 1.08-1.12). DISCUSSION: This is the first study, to our knowledge, finding increased levels of verified AD neuropathology in those with military service. Targeted veteran AD therapies is a pressing need.

Overcoming Barriers to Walk With Ease Implementation in Community Organizations.

INTRODUCTION: The Arthritis Foundation's Walk With Ease (WWE) program has been shown to reduce arthritis symptoms and increase physical performance for up to 1 year. However, research on community-based WWE implementation is limited. The purpose of this study was to examine early implementation at community organizations that received 1-year WWE implementation grants from the Osteoarthritis Action Alliance. METHOD: Program managers at five Osteoarthritis Action Alliance grantee organizations participated in 45-minute telephone interviews. Interviewees represented organizations with the highest WWE enrollment at 6 months (n = 3, >30% of goal enrollment) and no enrollment at 6 months (n = 2). The Planning for Sustainability framework guided qualitative analysis of factors affecting early implementation. RESULTS: All grantees were confident in WWE's evidence base, thought it a beneficial supplement to other programming, stressed the importance of senior leadership support for WWE, and engaged community partners for marketing support and as walking sites. Implementation experiences unique to low enrollment grantees were (1) recent major structural changes within their organization, (2) difficulties in communicating logistics internally, and (3) difficulties in balancing WWE with other responsibilities. All organizations experienced barriers that required altering their original implementation plans; however, practical solutions like adapting the program to improve flexibility, training organizational staff as leaders, and utilizing community partnerships served to address multiple barriers simultaneously. DISCUSSION: Building organizational capacity by overcoming early barriers is a key element of early implementation. Our findings offer concrete solutions to early WWE implementation barriers and suggest the need for further research on adaptations to improve WWE's flexibility in community organizations.

Association of Neighborhood-Level Disadvantage With Alzheimer Disease Neuropathology.

Importance: Social determinants of health, such as income, education, housing quality, and employment, are associated with disparities in Alzheimer disease and health generally, yet these determinants are rarely incorporated within neuropathology research. Objective: To establish the feasibility of linking neuropathology data to social determinants of health exposures using neighborhood disadvantage metrics (the validated Area Deprivation Index) and to evaluate the association between neighborhood disadvantage and Alzheimer disease-related neuropathology. Design, Setting, and Participants: This cross-sectional study consisted of decedents with a known home address who donated their brains to 1 of 2 Alzheimer disease research center brain banks in California and Wisconsin between January 1, 1990, and December 31, 2016. Neither site had preexisting social metrics available for their decedents. Neuropathologic features were obtained from each site for data collected using the standardized Neuropathology Data Set form and from autopsy reports. Data were analyzed from June 7 to October 10, 2019. Exposures: Geocoded decedent addresses linked to neighborhood disadvantage as measured by the Area Deprivation Index calculated for the year of death. Main Outcomes and Measures: Presence of Alzheimer disease neuropathology. The association between neighborhood disadvantage and Alzheimer disease neuropathology was evaluated via logistic regression, adjusting for age, sex, and year of death. Results: The sample consisted of 447 decedents (249 men [56%]; mean [SD] age, 80.3 [9.5] years; median year of death, 2011) spanning 24 years of donation. Fewer decedents (n = 24 [5.4%]) originated from the top 20% most disadvantaged neighborhood contexts. Increasing neighborhood disadvantage was associated with an 8.1% increase in the odds of Alzheimer disease neuropathology for every decile change on the Area Deprivation Index (adjusted odds ratio, 1.08; 95% CI, 1.07-1.09). As such, living in the most disadvantaged neighborhood decile was associated with a 2.18 increased odds of Alzheimer disease neuropathology (adjusted odds ratio, 2.18; 95% CI, 1.99-2.39). Conclusions and Relevance: The findings of this cross-sectional study suggest that social determinants of health data can be linked to preexisting autopsy samples as a means to study sociobiological mechanisms involved in neuropathology. This novel technique has the potential to be applied to any brain bank within the United States. To our knowledge, this is the first time Alzheimer disease neuropathology has been associated with neighborhood disadvantage.

Educational Attainment, Health Status, and Program Outcomes in Latino Adults With Arthritis Participating in a Walking Program.

INTRODUCTION: Latinos are disproportionately likely to lack a high school diploma, compared with non-Hispanic whites, a trend associated with worse outcomes in arthritis and indicating a need for health interventions. Camine Con Gusto (CCG) is the Spanish version of the evidence-based Walk With Ease program for arthritis. This study compared baseline health status and examined differences in program efficacy and adherence among Latino adults with and without a high school diploma enrolled in a pre-post evaluation of CCG. METHODS: CCG participants (n = 233) were classified into 2 groups: high school diploma or more (n = 129) and less than high school diploma (n = 104). We used logistic regression to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for associations of education with measures of baseline health and program adherence. We computed effect sizes for the difference between education groups by using mean change scores for arthritis symptoms, physical function, and psychosocial variables. RESULTS: The group without a high school diploma was more likely to report worse general health (OR = 2.40; 95% CI, 1.28-4.53) and lower levels of arthritis self-efficacy (OR = 1.95; 95% CI, 1.05-3.63) than the group with a high school diploma. CCG improved outcomes for both groups, with no significant between-group differences. The group without a high school diploma was less likely to read most of the program workbook (OR = 0.51; 95% CI, 0.27-0.97), but we found no significant differences in the amount of walking between the 2 groups. CONCLUSION: CCG was equally effective among Latinos with and without a high school diploma; however, education did affect participants' engagement with the program workbook. Adaptation of interventions for Latinos should consider how information can best be conveyed to those with lower levels of formal education.

Socioeconomic burden of pain in rheumatic disease.

Socioeconomic inequities in the health outcomes of rheumatic diseases, including pain, have been well documented across countries and study designs. Nevertheless, health disparities remain surprisingly-poorly understood in the rheumatic diseases, owing both to the complex nature of those disorders, and to methodological challenges surrounding the evaluation of social class and of its ties to health. Methodological difficulties in measuring SES can complicate interpretation of results to understand mechanisms of these associations. Current research on associations between SES and pain in rheumatic diseases are summarised in this article. Our review indicates that inequalities in pain in patients with OA and RA with low individual SES are strong and well-established, although associations in other rheumatic conditions and with community or childhood SES are less well-established. Further, the range of proposed mechanisms underlying disparities is broad, encompassing numerous indicators of SES, such as occupation, income, and education and varying widely by disease.

Evaluation of the Arthritis Foundation's Camine Con Gusto Program for Hispanic Adults With Arthritis.

INTRODUCTION: Camine Con Gusto (CCG) is the Hispanic version of an evidence-based walking program for people with arthritis. This study examined CCG outcomes, feasibility, tolerability, safety, and acceptability and potential tailoring. METHOD: A pre and post 6-week evaluation was conducted in Hispanic people with arthritis. Outcomes included pain, stiffness, fatigue, functional capacity, helplessness, and self-efficacy. A formative evaluation with program participants and key stakeholders explored program tailoring. RESULTS: Participants' mean age was 46.9 years, 44.4% had a high school degree or less, 2.5% were born in United States, 60.1% spoke only Spanish, and 74.7% were female. Moderate effect sizes were found: 0.50 for pain, 0.75 for fatigue, 0.49 for stiffness, 0.33 for function, 0.26 for helplessness, and 0.24 for self-efficacy. There were 285 participants recruited with an 82% 6-week retention (feasibility), no adverse events were reported (safety), and 98% reported program satisfaction (acceptability). Recommended adaptations included simpler language, more pictures and content addressing nutrition and chronic conditions, shortened materials, and inclusion of motivational strategies. CONCLUSION: CCG showed improvement in outcomes in Hispanic individuals comparable to those noted in non-Hispanic White and Black individuals with arthritis.
