Based on the premise that stressors can have a cumulative effect on people with dementia throughout the day that contributes to negative consequences later in the day, we examined if daytime activity, unit tumult, and mood were associated with sleep quality. A convenience sample of 53 long-term care (LTC) residents participated in this correlational study. Objective sleep quality was measured using actigraphy, and comorbid illness and level of dementia were control variables. Half of the sample had a sleep efficiency that was less than 80% and was awake for more than 90 min at night. Comorbid illness, negative mood at bedtime, and daytime activity level accounted for 26.1% of the variance in total sleep minutes. Census changes and the use of temporary agency staff were associated with poor sleep. Findings suggest daytime activity, mood at bedtime, and unit tumult should be considered when designing and testing interventions to improve sleep quality.

Abstract Sleep quality declines in old age and is particularly poor for long-term care (LTC) residents with dementia. Compromised sleep quality is associated with severe cognitive and neuropsychiatric symptoms, agitation, aggressiveness, and poor quality of life. Based on the premise that stressors can have a cumulative effect on people with dementia throughout the day that contributes to negative consequences later in the day, we examined if daytime activity, mood, and unit tumult were associated with sleep quality. A convenience sample of 53 LTC residents with dementia participated in this correlational study. Objective sleep quality and activity variables were measured using Actigraphy, and mood was measured by the Observed Emotion Rating Scale. Unit tumult was defined as events in the residents living area that are deviations from the typical day (i.e., census changes, being cared for by a certified nursing assistant from a temporary staffing agency, and lower than usual staffing level). Comorbid illness and level of dementia were control variables. Half of the sample had a sleep efficiency that was less than .85 and were awake for more than 90 minutes at night. Comorbid illness, negative mood at bedtime, and daytime activity level accounted for 26.1% of the variance in total sleep minutes. Census changes and the use of temporary agency staff were associated with poor total sleep time and sleep efficiency. Findings suggest that daytime activity, mood at bedtime, and unit tumult should be considered when designing and testing interventions to improve sleep quality among LTC residents with dementia.

Abstract Background: Patients suffering from chronic pain (CP) with overactivity frequently experience sleep disturbance. In order to improve the sleep disturbance of such individuals, changing their daytime activity patterns may be a key treatment strategy.Case presentation: The patient is a 35-year-old woman suffering from CP with sleep disturbance. First, cognitive behavioral therapy for insomnia was conducted to improve her sleep disturbance. However, due to the overactivity, she did not want to go to sleep earlier. Thus, she practiced activity pacing and changed her daytime activity patterns. Through activity pacing and cognitive restructuring, she stabilized her wake-up and bed times, and returned to work.Conclusions: To improve the sleep disturbance of individuals suffering from CP with overactivity, it is important to combine cognitive behavioral therapy for insomnia and activity pacing.

AbstractWe combined a high-resolution acoustic telemetry array with presence/absence receivers to conduct a preliminary study of the seasonal movements, activity patterns, and habitat associations of the newly described Deacon Rockfish (Sebastes diaconus). Eleven mature female Deacon Rockfish were tagged and monitored during an 11-month period, at a nearshore rocky reef off Seal Rock, Oregon, USA, an area of recurring seasonal hypoxia (defined as dissolved oxygen concentration [DO] < 2 mg l−1). Two tags were detected leaving the study area by day 35, indicating predation or emigration. Three tags became inactive within the array, indicating tag loss or fish death. Six “resident” fish inhabited the array for 246–326 days. Resident fish exhibited high site fidelity, small home ranges (mean 95% KDE = 4907 m2), and consistent activity patterns for the duration of the summertime high-resolution array (5 months), except during seasonal hypoxia. Resident fish were strongly diurnal in summer, with high levels of daytime activity above the bottom in relatively rugose habitat, followed by nighttime rest periods in deeper, less rugose habitat. During summertime hypoxia, resident fish exhibited less daytime activity during daytime hours with no rest periods at night, inhabited shallower water depths, and moved well away from their core activity areas on long, erratic forays. During the winter, diel patterns were less evident with higher activity levels at night (than in the summer) and lower activity levels in the day (than in the summer). We propose that some Deacon Rockfish continuously inhabit nearshore reefs throughout the year, but that daily/seasonal movement patterns, seasonally occurring hypoxia, and prey preferences for planktonic organisms influence relocation.

Working nonstandard work schedules is often associated with increased sedentary behavior and risk of sleep disorders. Night shift workers are prone to accumulating sleep debt, which they recover by sleeping during the day. The effect on daytime activity levels is unknown. The present study aims to objectively assess whether daytime sleep could affect daytime activity levels of shift worker nurses, resulting in an accumulation of their activity debt differently between working and rest periods. The study population (N = 37; mean age 41.7 ± 9.1 years) was composed of orthopedic nurses working on a rotating schedule, including either a night shift (NS) or only day/afternoon shift (DS). Actigraph monitoring lasted both on the working and the rest period. For the NS nurses, the working period recorded higher daytime activity levels than the rest period, while daytime sleep during the working and rest periods was similar. Conversely, DS nurses showed higher daytime activity levels and shorter daytime sleep during the working period. NS nurses were less active than DS nurses during the working period, probably because NS tended to have a longer daytime sleep. During the rest period, daytime activity levels for both groups were decreased. For NS nurses, sleep recorded the better sleep parameters during the rest period, while sleep parameters did not show significant differences between the working and the rest periods in DS. During the working period, NS nurses slept worse than the DS nurses. Both groups tended to accumulate a debt in daytime activity levels during the rest period. While daytime sleep may be an excellent way to counteract sleep debt and increase sleep duration over 24 h period, on the other hand, it makes nurses less active.

Activity patterns provide insight into the overall relationship between a species and its environment. Despite declines in populations of argali and some attention on ecological questions, limited information exists on argali behavior. We measured diurnal activity budgets of argali for 12 months by recording behavior (i.e., foraging, bedding, standing, traveling, other) with instantaneous scan sampling at 5-minute intervals. Argali exhibited seasonal differences in activity budgets. The greatest proportion of daytime in winter was spent foraging. The greatest proportion of daytime in summer was spent bedding. Argali reduced all other behaviors in winter in favor of foraging. In summer argali reduced their foraging to a seasonal low and increased bedding. Behavior was constrained by forage in winter and by temperatures in summer. Females fed more than males in all seasons. Other behaviors varied according to season and reproductive periods. Females demonstrated highest vigilance in spring and summer, while males exhibited highest vigilance during the autumn rut. These data are the first regarding detailed behavior of argali and are valuable to their management and conservation by providing information on constraints faced by the species.
