Actigraphic and Self-reported Sleep Measures in Older Adults: Factor Analytic Study.

Actigraphy has been used to measure older adults' sleep, but few studies have evaluated the factor structure among actigraphy-measured sleep parameters. Additionally, previous studies have reported the association between actigraphy-measured and self-reported sleep parameters in older adults but have not controlled for covariates of gender, insomnia, cognitive impairment, depression, and health conditions. We therefore investigated the factor structure of actigraphy-measured sleep parameters and, controlling for covariates, the association between actigraphy-measured and self-reported sleep parameters in 62 older adults (female: 75.

Sleep-Wake Disturbances and Episodic Memory in Older Adults.

Sleep-wake disturbances have been associated with episodic memory loss, but past studies were limited by use of single measures of objective or perceived disturbances. Notably, cognitive reserve and depressive symptoms have been associated with sleep-wake disturbances and poorer episodic memory in older adults. The aims of this study were to determine the relationship between episodic memory and sleep-wake disturbances using objective and perceived measures in older adults and to examine cognitive reserve and depressive symptoms as moderators of this relationship.

An Integrative Review of Brain-Derived Neurotrophic Factor and Serious Cardiovascular Conditions.

Background: There is emerging evidence that supports a role for brain-derived neurotrophic factor (BDNF) in the risk and presence of serious cardiovascular conditions. However, few existing literature reviews methodically describe empirical findings regarding this relationship.

Objectives: The purpose of this integrative review was to (a) evaluate BDNF (serum/plasma BDNF levels, BDNF Val66Met genotype) among humans at risk for or with serious cardiovascular conditions and (b) investigate the relationship between BDNF and risk/presence of serious cardiovascular conditions in humans.

Integrative Review of the Relationship Between Sleep Disturbances and Episodic Memory in Older Adults.

Impaired episodic memory in older adults has been linked to many factors. One of these factors is sleep disturbances, which are reported by more than 50% of older adults. The relationship between episodic memory and sleep disturbances remains unclear, however, because of the multiple types of measures of sleep and episodic memory used in previous studies.

Heart failure and skilled nursing facilities: review of the literature.

Background: Almost one-fourth of older adults hospitalized with heart failure (HF) are discharged to skilled nursing facilities (SNFs). The purpose of this review was to evaluate knowledge about HF patients discharged to SNFs to provide a foundation for future studies.

Methods And Results: A search was conducted of Medline, CINAHL, PubMed, and Google Scholar.
