Development of a novel strategy to understand the impact of shaving on skin health: combining tape strip exfoliation and human skin equivalent technology.

Introduction: The removal of unwanted hair is a widespread grooming practice adopted by both males and females. Although many depilatory techniques are now available, shaving remains the most common, despite its propensity to irritate skin. Current techniques to investigate the impact of shaving regimes on skin health rely on costly and lengthy clinical trials, which hinge on recruitment of human volunteers and can require invasive biopsies to elucidate cellular and molecular-level changes.

Sleep Mediates Age-Related Executive Function for Older Adults with Limited Cognitive Reserve.

Objective: Sleep quantity and quality are associated with executive function (EF) in experimental studies, and in individuals with sleep disorders. With advancing age, sleep quantity and quality decline, as does the ability to perform EF tasks, suggesting that sleep disruption may contribute to age-related EF declines. This cross-sectional cohort study tested the hypothesis that poorer sleep quality (i.

Does the Key Task Measure Prospective Memory? Cautionary Findings from Parallel Studies in HIV Disease and Older Adults.

Objective: Despite its brevity and face validity, little is known about the construct validity of the naturalistic "Key Task" of prospective memory (PM), in which an examinee is instructed to remind the examiner at a designated time to retrieve keys (or another belonging) placed out of sight.

Method: Study 1 included 162 HIV+ and 52 HIV- comparison participants who completed the Key Task alongside well-validated measures of PM and a comprehensive neuropsychological battery that included everyday functioning measures. Study 2 used broadly parallel methods in 168 older community-dwelling Australians.

Repeatable Battery for the Assessment of Neuropsychological Status (RBANS): Normative Data for Older Adults.

Objective: Provide updated older adult (ages 60+) normative data for the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), Form A, using regression techniques, and corrected for education, age, and gender.

Method: Participants (aged 60-93 years; N = 415) were recruited through the Healthy Ageing Research Program (HARP), University of Western Australia, and completed Form A of the RBANS as part of a wider neuropsychological test battery. Regression-based techniques were used to generate normative data rather than means-based methods.

Sleep disruption explains age-related prospective memory deficits: implications for cognitive aging and intervention.

The high prevalence of sleep disruption among older adults may have implications for cognitive aging, particularly for higher-order aspects of cognition. One domain where sleep disruption may contribute to age-related deficits is prospective memory-the ability to remember to perform deferred actions at the appropriate time in the future. Community-dwelling older adults (55-93 years, N = 133) undertook assessment of sleep using actigraphy and participated in a laboratory-based prospective memory task.

Retrieval cue and delay interval influence the relationship between prospective memory and activities of daily living in older adults.

Objective: Older adults commonly experience mild declines in everyday functioning and the strategic aspects of prospective memory (PM). This study used multiprocess theory to examine whether the strategic demands of retrieval cue type (event vs. time based) and delay interval length (2 vs.

Does prospective memory influence quality of life in community-dwelling older adults?

Older adults commonly experience declines in prospective memory, which describes one's ability to "remember to remember," and can adversely affect instrumental activities of daily living and healthcare compliance. However, the extent to which prospective memory failures may influence quality of life in typically aging older adults is not well understood. One-hundred and four community-dwelling older Australians (aged 50 to 82 years) were administered a comprehensive, neuropsychological battery that included the Memory for Intentions Screening Test (MIST), Prospective and Retrospective Memory Questionnaire (PRMQ), Instrumental Activities of Daily Living Questionnaire (IADLQ), and World Health Organization Quality of Life-8 (WHOQOL-8).
