RESUMEN

A patient with severe aortic stenosis and left ventricular hypertrophy underwent a transcatheter aortic valve replacement. The patient's blood pressure significantly dropped after protamine administration. A diagnosis of suicide left ventricle post-valve replacement was made. The diagnosis and management of the protamine reaction are detailed. This case highlights the need to slowly infuse protamine sulfate and monitor for adverse events.

RESUMEN

The transcatheter aortic valve replacement procedure is used in patients with aortic stenosis. Transcatheter aortic valve replacement devices are quite versatile; thus, they are increasingly being used for nonaortic applications, such as tricuspid valve-in-valve implantation. This case series describes a transcatheter aortic valve replacement procedure in 4 patients with anatomic challenges (eg, aortic tortuosity, high valvular calcium burden, highly calcified bicuspid valve, low coronary artery takeoff, left main coronary artery occlusion, and large aortic annulus) and a fifth patient who had a failed tricuspid bioprosthesis and underwent a tricuspid valve-in-valve implantation with the Edwards SAPIEN 3 transcatheter heart valve (Edwards Lifesciences). All procedures required adjustments to the standard protocol, and each procedure was successful. The critical, technical adjustments in the deployment technique and preprocedural planning of the procedures are detailed to provide a road map for other cardiologists who encounter similar challenges.

RESUMEN

Comparative effectiveness of behavioral interventions to mitigate the impacts of degeneration-based cognitive decline is not well understood. To better address this gap, we summarize the studies from the Healthy Action to Benefit Independence & Thinking (HABIT®) program, developed for persons with mild cognitive impairment (pwMCI) and their partners. HABIT® includes memory compensation training, computerized cognitive training (CCT), yoga, patient and partner support groups, and wellness education. Studies cited include (i) a survey of clinical program completers to establish outcome priorities; (ii) a five-arm, multi-site cluster randomized, comparative effectiveness trial; (iii) and a three-arm ancillary study. PwMCI quality of life (QoL) was considered a high-priority outcome. Across datasets, findings suggest that quality of life was most affected in groups where wellness education was included and CCT withheld. Wellness education also had greater impact on mood than CCT. Yoga had a greater impact on memory-dependent functional status than support groups. Yoga was associated with better functional status and improved caregiver burden relative to wellness education. CCT had the greatest impact on cognition compared to yoga. Taken together, comparisons of groups of program components suggest that knowledge-based interventions like wellness education benefit patient well-being (e.g., QoL and mood). Skill-based interventions like yoga and memory compensation training aid the maintenance of functional status. Notably, better adherence produced better outcomes. Future personalized intervention approaches for pwMCI may include different combinations of behavioral strategies selected to optimize outcomes prioritized by patient values and preferences.

RESUMEN

OBJECTIVES: This study evaluated the efficacy of a multidomain brain health intervention on health behavior change and sought to understand whether health literacy or brain health knowledge predicted engagement with the intervention. METHODS: One-hundred thirty midlife and older adults were assigned to one of three intervention conditions: brain fitness (B-Fit) utilizing education and goal setting, education-only, or waitlist. Questionnaires were completed at baseline and post-intervention. RESULTS: Both B-Fit and education-only conditions reported improvements in health behaviors over time. Although effect size for the education-only condition was moderate, only the B-Fit condition differed significantly in health behaviors from the waitlist post-intervention. Lower baseline brain health knowledge predicted improvements in health behaviors for education-only condition. DISCUSSION: The multidomain brain health intervention was successful in helping participants change their behaviors, but it was not more effective than the education-only condition. For those with lower brain health knowledge, an education-only intervention may be sufficient to encourage behavior change.

RESUMEN

OBJECTIVE: This study used multiple assessment methods to examine instrumental activities of daily living (IADLs) performance in individuals with Parkinson's disease with mild cognitive impairment (PD-MCI) compared to individuals with mild cognitive impairment (MCI) and cognitively healthy older adults (HOA). Associations between functional performance and cognition were also examined. METHODS: Eighteen individuals with PD-MCI, 48 individuals with MCI, and 66 HOAs were assessed with multiple IADL measures, including direct observation, a performance-based measure, and self- and informant-report questionnaires. Performance on the direct-observation measure was further characterized by coding for four error types: omissions, substitutions, and inefficient and irrelevant/off-task actions. RESULTS: Both the PD-MCI and MCI groups performed more poorly on the overall score for all IADL measures relative to HOAs. Although the PD-MCI and MCI groups did not differ in overall performance, on the direct-observation measure, the PD-MCI group took longer and made more inefficient and irrelevant/off-task errors relative to the HOA and MCI groups, whereas the MCI group made more omission and substitution errors relative to HOAs. Further, the pattern of cognitive correlates that associated most strongly with the functional measures varied across groups and functional assessment methods. CONCLUSION: Compared to HOAs, PD-MCI and MCI groups demonstrated increased difficulties performing everyday activities, and cognitive and motor abilities differentially contributed to the everyday task difficulties of these two groups.

RESUMEN

OBJECTIVE: The night out task (NOT) was developed as a naturalistic, open-ended, multitasking measure that requires individuals to complete eight subtasks comparable to those encountered during real-world functioning (e.g., pack travel bag, prepare tea). We examined psychometric properties and administration feasibility of this direct observation measure within a clinic-like setting using a tablet-based coding application. METHOD: A sample of 148 community-dwelling older adults (82% cognitively healthy; 18% mild cognitive impairment) and 57 younger adults completed the NOT along with other neurocognitive tests and questionnaires. RESULTS: Inter-rater reliability across NOT primary (i.e., time, accuracy, efficiency) and process-related (e.g., error-types, self-corrections) variables was mostly excellent. NOT primary measures showed expected patterns of convergent and discriminant validity with measures of cognition, demographics, and well-being. External validity was established by the NOT ability to distinguish between age and diagnostic (cognitively healthy vs. mild cognitive impairment) groups. Demonstrating incremental validity, the NOT primary variables (execution time in particular) were predictive of self-reported functional abilities and completion quality of in-home everyday tasks over and earlier variables such as demographics, cognition, and mobility. CONCLUSIONS: These findings suggest that the NOT and its app interface, which allows for continuous logging of observations, are a feasible in-clinic measure to assess cognitive capacities important for real-world functioning. With further validation, the NOT may allow for earlier detection of functional difficulties. Understanding errors and strategies used during NOT performance could also have implications for individualized interventions.

RESUMEN

OBJECTIVES: Accumulating research indicates that engaging in healthy lifestyle behaviors (e.g. exercise, cognitive and social engagement, stress reduction) can prevent illness and disability as people age and improve mental health. The Healthy Aging Activity Engagement (HAAE) scale was developed to holistically assess an individual's level of engagement in healthy aging behaviors across multiple health domains. METHODS: Participants were 275 healthy younger, midlife and older adults. Participants rated engagement in 38 healthy aging lifestyle behaviors over the past 7 days on a scale from 1 (strongly disagree) to 5 (strongly agree). RESULTS: Traditional measurement analysis and Rasch modelling techniques resulted in a 32-item scale with three subscales representing biologic health, social and cognitive strategies, and health safeguard behaviors. With the exception of the health safeguard subscale, the HAAE total score and subscales demonstrated good internal consistency, test-retest reliability, convergent and discriminant validity, and responsiveness to a program designed to promote engagement in healthy brain aging behaviors. DISCUSSION: With further validation, the HAAE may be useful for holistic clinical assessment of behaviors that promote healthy aging, support brain and mental health, and for treatment planning. Furthermore, the HAAE can be used to measure the outcome of multi-domain lifestyle interventions.

RESUMEN

OBJECTIVE: This study examined content and temporal order memory for subject-performed activities in an incidental learning condition in cognitively healthy individuals with Parkinson's disease (PD) (N = 20) and controls (N = 20). METHOD: Participant's free recall of activities provided a measure of content memory. Temporal order memory was assessed with a reconstruction task of activities. Self- and informant-reports of everyday memory were used to examine the relationship between everyday memory, and content and temporal order memory. RESULTS: Individuals with PD recalled fewer activities although recognition memory was intact. Temporal order memory was also impaired for individuals with PD. For the PD group, both self- and informant-reports of changes in current memory abilities were strongly associated with temporal order memory but not content memory for activities. CONCLUSIONS: These findings suggest that there is a strong link between everyday memory abilities and temporal order memory for activities, and support the need for additional study of temporal order memory abilities in PD.

RESUMEN

OBJECTIVE: Few studies have examined functional abilities and complaints in healthy older adults (HOAs) with subjective cognitive concerns (SCC). The aims of this study were to assess everyday functioning in HOAs reporting high and low amounts of SCC and examine cognitive correlates of functional abilities. METHOD: Twenty-six HOAs with high SCC and 25 HOAs with low SCC, as well as their knowledgeable informants, completed the Instrumental Activities of Daily Living-Compensation (IADL-C), a questionnaire measure of everyday functioning. RESULTS: After controlling for depression, the high-SCC group self-reported significantly more everyday difficulties on the IADL-C, including all subdomains. Compared to the low-SCC group, informants for the high-SCC group endorsed more difficulties on the IADL-C and specifically the social skills subdomain. For the high-SCC group, poorer self-report of everyday functioning was related to poorer executive functioning and temporal order memory. CONCLUSIONS: These findings indicate that there may be subtle functional changes that occur early in the spectrum of cognitive decline in individuals with high SCC, and these functional changes are evident to informants. Further work is needed to investigate whether individuals with both SCC and functional difficulties are at an even higher risk for progression to mild cognitive impairment.

RESUMEN

Everyday functioning and its executive functioning cognitive correlates (i.e., switching, inhibition, and updating) were investigated in healthy older adults (HOAs) using multiple methods of functional status. In addition to whether computerized experimental tasks would better dissociate these subcomponents than neuropsychological measures of executive functioning, we were also interested in the contributions of both experimental and neuropsychological measures of executive function subcomponents to functional abilities. Seventy HOAs (45 young-old and 25 old-old) and 70 younger adults completed executive function and neuropsychological tests. In addition to self- and informant questionnaires of functional abilities, HOAs completed two performance-based measures. An aging effect was found on all executive function measures. Old-old older adults and their informants did not report more functional difficulties but demonstrated more difficulties on performance-based measures than did young-old participants. For the HOAs, after controlling for age and education, the neuropsychological measures of executive functioning, but not experimental measures, explained a significant amount of variance in the informant-report and both performance-based measures. Updating measures differentially predicted performance-based measures, while switching was important for questionnaire and performance-based measures. The contribution of executive functioning to functional status when measured with experimental measures specifically designed to isolate the executive subcomponent was not as strong as hypothesized. Further research examining the value of isolating executive function subcomponents in neuropsychological assessment and the prediction of functional abilities in older adults is warranted.

RESUMEN

Everyday memory lapses experienced by older adults (OAs) were examined using a daily-diary checklist and retrospective questionnaire. In Experiment 1, 138 younger and 138 OAs indicated the frequency of forgetting of 16 memory lapses, and whether each occurred daily during the course of a week. OAs reported more memory lapses on the questionnaire, but not the daily diary. OAs reported more frequently forgetting names and words, while younger adults had more difficulty with appointments and personal dates. Fewer memory lapses on the daily diary were related to better performance on a laboratory-memory measure for OAs. In Experiment 2, 62 OAs returned for a five-year follow-up and endorsed experiencing more memory lapses on the daily diary compared to baseline, specifically forgetting more names and words, but not the retrospective questionnaire. Daily checklist memory lapses again correlated with the laboratory-memory measure. A daily checklist may be a viable way to assess everyday memory lapses.

RESUMEN

The objective of this meta-analysis was to improve understanding of the heterogeneity in the relationship between cognition and functional status in individuals with mild cognitive impairment (MCI). Demographic, clinical, and methodological moderators were examined. Cognition explained an average of 23% of the variance in functional outcomes. Executive function measures explained the largest amount of variance (37%), whereas global cognitive status and processing speed measures explained the least (20%). Short- and long-delayed memory measures accounted for more variance (35% and 31%) than immediate memory measures (18%), and the relationship between cognition and functional outcomes was stronger when assessed with informant-report (28%) compared with self-report (21%). Demographics, sample characteristics, and type of everyday functioning measures (i.e., questionnaire, performance-based) explained relatively little variance compared with cognition. Executive functioning, particularly measured by Trails B, was a strong predictor of everyday functioning in individuals with MCI. A large proportion of variance remained unexplained by cognition.

RESUMEN

Everyday multitasking and its cognitive correlates were investigated in an older adult population using a naturalistic task, the Day Out Task. Fifty older adults and 50 younger adults prioritized, organized, initiated, and completed a number of subtasks in a campus apartment to prepare for a day out (e.g., gather ingredients for a recipe, collect change for a bus ride). Participants also completed tests assessing cognitive constructs important in multitasking. Compared to younger adults, the older adults took longer to complete the everyday tasks and more poorly sequenced the subtasks. Although they initiated, completed, and interweaved a similar number of subtasks, the older adults demonstrated poorer task quality and accuracy, completing more subtasks inefficiently. For the older adults, reduced prospective memory abilities were predictive of poorer task sequencing, while executive processes and prospective memory were predictive of inefficiently completed subtasks. The findings suggest that executive dysfunction and prospective memory difficulties may contribute to the age-related decline of everyday multitasking abilities in healthy older adults.

RESUMEN

OBJECTIVE: The day-out task (DOT), a naturalistic task that requires multitasking in a real-world setting, was used to examine everyday functioning in individuals with mild cognitive impairment (MCI). METHOD: Thirty-eight participants with MCI and 38 cognitively healthy older adult controls prioritized, organized, initiated, and completed a number of subtasks in a campus apartment to prepare for a day out (e.g., determine and gather change for bus, bring a magazine). Participants also completed tests assessing cognitive constructs important in multitasking (i.e., retrospective memory, prospective memory, planning). RESULTS: As compared with controls, the MCI group required more time to complete the DOT and demonstrated poorer task accuracy, performing more subtasks incompletely and inaccurately. Despite poorer DOT task accuracy, the MCI and control groups approached completion of the DOT in a similar manner. For the MCI group, retrospective memory was a unique predictor of the number of subtasks left incomplete and inaccurate, while prospective memory was a unique predictor of DOT sequencing. The DOT measures, but not the cognitive tests, were predictive of knowledgeable informant report of everyday functioning. CONCLUSIONS: THESE findings suggest that difficulty remembering and keeping track of multiple goals and subgoals may contribute to the poorer performance of individuals with MCI in complex everyday situations.

RESUMEN

This community needs assessment surveyed 21 administrators and 75 direct care staff at 9 larger and 12 smaller assisted living facilities (ALFs) regarding perceptions of resident mental health concerns, direct care staff capacity to work with residents with mental illness, and direct care staff training needs. Group differences in these perceptions were also examined. Both administrators and directcare staff indicated that direct care staff would benefit from mental health-related training, and direct care staff perceived themselves as being more comfortable working with residents with mental illness than administrators perceived them to be. Implications for gerontological social work are discussed.
