Strategies to Locate Lost Persons with Dementia: A Case Study of Ontario First Responders.

Information on strategies and practices in the search of missing persons with dementia is inconsistent which creates challenges for first responders, such as police, when they choose appropriate search and rescue approaches. The purpose of this study was to describe current strategies among police services in Ontario. Telephone interviews with police were conducted. Questions included what strategies were used for locating missing persons living with dementia, and what gaps exist in search practices. Participants described they used high- and low-tech solutions in search and rescue. They identified gaps in education and awareness, proactive strategies, resources, and funding. Information collected from the interviews was used to develop a practice guideline for police in partnership with the Alzheimer Society of Ontario.

Development and validation of a conceptual model and strategy adoption guidelines for persons with dementia at risk of getting lost.

Various solutions are available to address critical wandering; however, no guideline exists to allow for the successful adoption of these strategies. This study developed and validated a conceptual model and series of guidelines to facilitate choice of wander-management strategies. Face and content validity of the model and guidelines were assessed through an online and paper survey, individual interviews and focus groups across stakeholders. Directed content analysis was performed. Overall impression of the conceptual model and guidelines was positive. Valued features included the guidelines' ability to help users in choosing proactive wander-management strategies. Suggested changes included revisions in terminology and more factors and strategies to be added to the model and guidelines. This work is being disseminated and used by persons with dementia, caregivers, health practitioners and community service providers to identify strategies to mitigate the risks associated with critical wandering.

Dissemination and implementation of strategy adoption guidelines for persons with dementia at risk of getting lost.

OBJECTIVES: To address risks associated with critical dementia-related wandering, three guidelines were developed for use by persons living with dementia, their care partners, and professional staff, to choose wander-management strategies. This evidence-based research incorporates knowledge mobilization approaches that directly involve the three types of stakeholders in using the guidelines in the real world. The purpose of this project was to evaluate the knowledge translation of three guidelines on wander-management strategies, and to further deploy these guidelines to organizations across Canada. METHODS: Steering committees across Canada were established for consultation. Guidelines were then shared among these organizations via Google slides. Health professionals, caregivers, community organizations and persons living with dementia completed an online survey (via Google) or paper-based survey to provide feedback on the guidelines. The guidelines were then translated from English to French using a forward-translation method. RESULTS: The guidelines were adopted across ten organizations in four Canadian provinces. Adoption included introduction and formal training to staff. It took 22 months from the development of the guidelines to the dissemination and launch of the guidelines to the organizations. Participants (n = 73) were very satisfied with the developed guidelines and agreed they were easy to navigate, easy to understand, and the information provided was useful. CONCLUSIONS: A stakeholder-driven approach used for guideline development and dissemination were successful methods for minimizing the time for this work to become practice. This in addition to the use of online platforms can replace conventional methods which take longer and become quickly outdated.

Evaluation of antecedent behaviors of dementia-related wandering in community and facility settings.

Aim: To understand antecedent behaviors to critical wandering among persons living with dementia in or outside of a facility. Materials & methods: Caregivers were asked to write down the type and number of antecedent behaviors they observed in persons with dementia that were about to critically wander for 2-4 weeks. Observations were made through a developed questionnaire. Results: Six antecedent behaviors were observed: stating intent to leave, door lingering/tampering, preparing to go outside, packing up belongings, calling to be picked up and draw to outside stimuli. Conclusion: Information from this study can be used in the education of wander-management strategy adoption among caregivers of persons with dementia at risk of getting lost.

Age and sex-related decline of muscle strength across the adult lifespan: a scoping review of aggregated data.

Muscle strength is sex-related and declines with advancing age; yet, a comprehensive comparative evaluation of age-related strength loss in human females and males has not been undertaken. To do so, segmented piecewise regression analysis was performed on aggregated data from studies published from 1990 to 2018 and are available in CINAHL, EMBASE, MEDLINE, and PsycINFO databases. The search identified 5613 articles that were reviewed for physical assessment results stratified by sex and age. Maximal isometric and isokinetic 60°·s-1 knee extension (KE) and knee flexion (KF) contractions from 57 studies and 15 283 subjects (N = 7918 females) had sufficient data reported on females and males for meaningful statistical evaluation to be undertaken. The analysis revealed that isometric KE and KF strength undergo similar rapid declines in both sexes late in the sixth decade of life. Yet, there is an abrupt age-related decline in KE 60°·s-1 peak torque earlier in females (aged 41.8 years) than males (aged 66.7 years). In the assessment of KF peak torque, an age-related acceleration in strength loss was only identified in males (aged 49.3 years). The results suggest that age-related isometric strength loss is similar between sexes while the characteristics of KE and KF peak torque decline are sex-related, which likely explains the differential rate of age-related functional decline. Novelty Inclusion of muscle strength and torque of KE and KF data from >15 000 subjects. Isometric KE and KF strength loss are similar between sexes. Isokinetic 60°·s-1 KE torque decline accelerates 25 years earlier in females and female age-related KF peak torque decline does not accelerate with age.

EMG Functional tasks recordings determines frailty phenotypes in males and females.

BACKGROUND: Identification of frailty is essential to understanding and mitigating age-related physical impairments. Previous studies have indicated that frailty phenotype can be identified through electromyography (EMG) when collected over the course of an 8-h day. However, long duration recordings challenge both the clinician and the older adults but activities of daily living that are most sensitive to changes in frailty status are currently unknown. The purpose of this study was to determine if muscle activity recorded during specific task, or groups of tasks, could be used to correctly classify middle-aged, non-frail, pre-frail, and frail older adult pheonotypes. METHODS: Fifteen middle-aged (49 ± 5 years) and 76 older adults (77 ± 8 years) participated. Older adults were categorized as non-frail (n = 49), pre-frail (n = 20), or frail (n = 7) using self-selected normal gait speed and a modified frailty index score. Bursts and gaps in EMG of the biceps brachii, triceps brachii, vastus lateralis, and biceps femoris were measured bilaterally during nine different functional tasks. RESULTS: Relatively high levels of success for frailty group classification (near 90%) can be achieved from EMG. Bursts were more frequent and gaps fewer in frail compared with middle-aged and non-frail adults. The numbers of gaps and muscle quiescence in the upper limbs were particularly important. Changes in muscle activity offer predictive value in identifying frailty phenotype. Completing functional tasks (rising from the floor, toilet and chair) while undergoing EMG assessment can contribute to the identification of differences in frailty phenotype among older adults.

Adjustment and vocational satisfaction of patients treated during childhood or adolescence for acute lymphoblastic leukemia.

This investigation evaluated the psychosocial consequences of the diagnosis and treatment of acute lymphoblastic leukemia (ALL) on the long-term adjustment of a sample of 46 patients less than 20 years of age at diagnosis (mean age: 7.46 years). Subjects were followed up for an average of 15.4 years after diagnosis and were a mean of 22.87 years old at assessment. A sample of Hodgkin's disease and non-Hodgkin's lymphoma survivors served as a comparison group. Patients completed standardized measures of well-being, stress reaction, vocational satisfaction, and a questionnaire assessing defensiveness regarding their history of cancer treatment, experienced job discrimination, and social involvement. Overall, the subjects appeared to be well-adjusted; female subjects, however, exhibited an increased tendency to experience anxiety in stressful situations. Vocational discrimination did not appear to be a significant problem for this group of survivors, and subjects exhibited levels of vocational satisfaction that did not differ from population norms. Greater defensiveness regarding a history of cancer treatment was associated with lower levels of well-being and heightened stress reaction. Survivors who received CNS prophylaxis that included cranial irradiation had lower well-being scores than did those survivors receiving only intrathecal methotrexate.
