Interpretive Qualitative Evaluation Informs Research Participation and Advocacy Training Program for Seniors: A Pilot Study.

Background: An 8-week educational intervention co-taught by medical students and faculty was designed to foster communication between clinical researchers and populations of interest to ultimately increase participation in clinical research by older adults, including underrepresented groups. Weekly topics focused on age-related changes and health conditions, socio-contextual factors impacting aging populations, and wellness strategies. Objectives: To evaluate the successes and weaknesses of an educational intervention aimed at increasing the participation of older adults in clinical research. Design: A focus group was assembled after an 8-week educational intervention, titled DREAMS, to obtain participants' feedback on the program, following a pre-formulated interview guide. Settings: Participants were interviewed in a health center office environment in the United States of America in April of 2016. Participants: A post-intervention focus group was conducted with a group of eight older adults (mean age = 75.8 ± 11.4 years) from 51 total participants who completed the intervention. Methods: The focus group was interviewed loosely following a pre-formed question guide. Participants were encouraged to give honest feedback. The conversation was recorded, transcribed verbatim, and analyzed using thematic analyses. Results: While participants viewed most aspects of the study as a success and stated that it was a productive learning experience, most participants had suggestions for improvements in the program content and implementation. Specifically, the composition of and direction to small breakout groups should be carefully considered and planned in this population, and attention should be paid to the delivery of sensitive topic such as death and dementia. A clear main benefit of this programmatic approach is the development of a rapport amongst participants and between participants and clinical researchers. Conclusions: The results provide useful insights regarding improving participation among hard-to-reach and historically underrepresented groups of older adults in clinical research. Future iterations of this program and similar educational interventions can use these findings to better achieve the programmatic objectives.

Relationship between parental history of dementia, motor-cognitive and executive function performance in African American women.

People with parental history (PH) of Alzheimer's Disease (AD) and Alzheimer's Disease and related dementias (ADRD) are themselves at risk of developing dementia. ADRD are more prevalent in African Americans and women. A decline in executive function and motor-cognitive integration can cause an impaired performance of functional skills. The monitoring of cognitive and psychosocial function in individuals with a PH of ADRD is important for implementing interventions to delay or prevent ADRD diagnosis. This study compared 58 African American women (M age = 63.2 ± 7.2 years) with PH of ADRD (n = 34) versus without PH (NPH; n = 24) on the performance of motor-cognitive and executive function tasks, and mental and physical quality of life (QOL) using point biserial correlations and linear regression. Linear regression revealed no difference between participants with and without PH on motor-cognitive tests. However, compared to participants with NPH, participants with PH of ADRD performed significantly worse on the DKEFS (Delis Kaplan Executive Function System) Tower Test (PH: M = 9.9 ± 2.0; NPH: M = 11.5 ± 4.3; p = 0.046), had poorer mental QOL (PH: M = 46.8 ± 10.7; NPH: M = 52.8 ± 7.8 l; p = 0.007); and physical QOL (PH: M = 40.9 ± 9.3; NPH: M = 44.7 ± 8.6; p = 0.023). African American women at risk for ADRD may exhibit deficiencies in executive function and physical and mental quality of life before memory deficits meet the criterion for ADRD diagnosis. Motor-Cognitive tasks may be preserved. Executive function and mental and physical health-related QOL may be important targets for identifying individuals at increased risk for ADRD and developing appropriate rehabilitative interventions.

A Pilot randomized clinical trial of adapted tango to improve cognition and psychosocial function in African American women with family history of Alzheimer's disease (ACT trial).

Alzheimer's disease (AD) is a devastating, progressive neurodegenerative disease resulting in memory loss and a severe reduction in the ability to perform activities of daily living. Ethnicity-related genetic factors promoting the development of dementias among African Americans (AA) and increased risk among women for developing AD indicates that AA women with a parental history of AD are at great risk for developing AD. This phase I study assessed the impact of a 12 week, 20-lesson adapted Argentine Tango intervention (n = 24) to a no-contact control group (n = 10) on measures of plasma inflammatory markers, cognition, and motor and psychosocial performance in middle-aged AA woman at increased risk for AD by virtue of parental history. Some woman (n = 16) were also caregivers; thus, the impact of the intervention on caregiving burden was examined in this subset. Preliminary analysis of efficacy was conducted with significance tests on biomarkers and key measures of cognition, including visuospatial and executive function, balance, and strength. After 12 weeks, Tango participants had significantly decreased inflammatory cytokine, including reductions in IL-7 (p = 0.003), IFN-γ (p = 0.011), TNFα (p = 0.011), and MCP-1 (p = 0.042) compared to controls. Large effects were noted for the Tango group on tests of executive functioning (d = 0.89), and inhibition (p = 0.031). Participants in Tango improved in dynamic and static balance (p = 0.018) and functional lower body strength (p = 0.023). Secondary assessment revealed trends favoring the intervention group were noted in spatial cognition and executive function. Moderate effects were noted in caregiving burden measures among the subset of caregivers. These data demonstrate substantial reductions in inflammatory biomarkers along with cognitive and motor improvements through a non-pharmacologic, affordable intervention among a small, well-characterized cohort of AA women with a parental history of AD.

Improved Mobility, Cognition, and Disease Severity in Corticobasal Degeneration of an African American Man After 12 Weeks of Adapted Tango: A Case Study.

Corticobasal degeneration (CBD) has no available treatment to slow disease progression and generally resists drug therapy. Corticobasal degeneration has symptoms and decreased quality of life similar to Parkinson disease. Adapted Tango, a successful rehabilitation for Parkinson, may address CBD. A 63-yr-old African American man with CBD (alias: YD; CBD duration = 2 yrs) was evaluated for motor, cognitive, and psychosocial function before, immediately after, 1 mo after, and 6 mos after 12 wks of 20, biweekly 90-min adapted-tango lessons. After intervention, disease-related motor symptoms improved and YD reported fewer problems in nonmotor experiences of daily living, which include mood, cognition, pain, fatigue, etc. Motor symptoms remained above baseline at 6-mo posttest. YD's balance confidence improved after intervention but declined below baseline at 6-mo posttest. Quality of life was maintained despite worsened depression. YD improved or maintained executive function, and visuospatial function and attention at posttest and 1-mo posttest. At posttest, YD maintained mobility and improved on dynamic balance. At 1-mo posttest, most mobility measures had improved relative to baseline. However, YD showed executive function and overall motor decline 6 mos after intervention. Adapted tango may have temporarily slowed disease progression and improved or maintained mobility and cognition. Gains were poorly maintained after 6 mos. Further study is warranted.

Rationale and Design of a Clinical Trial of Adapted Tango to Improve Negative Health Impacts in Middle Aged African-American Female Caregivers of Persons with Alzheimer's Disease (ACT Trial).

Alzheimer's disease (AD) is a devastating progressive neurodegenerative disease resulting in memory loss and a severe reduction in ability to perform activities of daily living. The role of caring for someone with AD frequently falls to female family members, often daughters. The burden of caregiving can increase stress and anxiety and cause health decline in the caregiver. The combination of ethnicity-related genetic factors promoting the development of dementias among African-Americans (AA) and the increased risk among women for developing AD means that AA women who are caregivers of a parent with AD are at great risk for developing dementias including AD. The proposed study would compare the cognitive, motor, and psychosocial benefits of a well-established 12 week, 20-lesson adapted Argentine Tango intervention (N = 30) to a no-contact control group (N = 10) in middle-aged (45-65 years) AA women who are caregivers of a parent with AD in the metro Atlanta area.
