BACKGROUND: Sleep disturbance during intensive care unit (ICU) admission is common and severe. Sleep disturbance has been observed in survivors of critical illness even after transfer out of the ICU. Not only is sleep important to overall health and well-being, but patients after critical illness are also in a physiologically vulnerable state. Understanding how sleep disturbance impacts recovery from critical illness after hospital discharge is therefore clinically meaningful. OBJECTIVE: This systematic review aimed to summarize studies that identify the prevalence of and risk factors for sleep disturbance after hospital discharge for critical illness survivors...

Physiological evidence suggests that sleep modulates kidney function. Our objective was to examine the cross-sectional association between kidney function and objectively-estimated habitual sleep duration, quality and timing in a cohort of patients with mild to moderate chronic kidney disease. This study involved two US clinical centers of the Chronic Renal Insufficiency Cohort (CRIC) study, including 432 participants in a CRIC ancillary sleep study. Habitual sleep duration, quality and timing were measured using wrist actigraphy for 5-7 days...

OBJECTIVES: Night workers often experience high levels of sleepiness due to misalignment of the sleep-wake cycle from the circadian pacemaker, in addition to acute and chronic sleep loss. Exposure to light, in particular short wavelength light, can improve alertness and neurobehavioural performance. This randomised controlled trial examined the efficacy of blue-enriched polychromatic light to improve alertness and neurobehavioural performance in night workers. DESIGN: Participants were 71 night shift workers (42 males; 32...

Atopic dermatitis is a chronic inflammatory skin condition affecting both children and adults and is associated with pruritus. A method for objectively quantifying nocturnal scratching events could aid in the development of therapies for atopic dermatitis and other pruritic disorders. High-resolution wrist actigraphy (3-D accelerometer sensors sampled at 20 Hz) is a non-invasive method to record movement. This work presents an algorithm to detect nocturnal scratching events based on actigraphy data. The twofold process consists of segmenting the data into "no motion", "single handed motion" and "both handed motion" followed by discriminating motion segments into scratching and other motion using a bi-directional recurrent neural network classifier...

PURPOSE: Although the clinical usefulness of actigraphy (ACT) in chronic insomnia disorder (CID) is extensively investigated, the evaluation on the utility of ACT in sleep-disordered breathing (SDB) is limited and the report of comparison with perceived sleep by patients and polysomnography (PSG) is scarce. METHODS: Thirty-six patients with SDB and 30 with CID underwent PSG and ACT, and they reported perceived sleep time and latency simultaneously. Sleep parameters (total sleep time [TST], sleep onset latency [SOL], sleep efficiency, and wakefulness after sleep onset [WASO]) were compared...

BACKGROUND: Experimental and epidemiologic data suggest that among non-pregnant adults, sleep duration may be an important risk factor for chronic disease. Although pregnant women commonly complain of poor sleep, few studies have objectively evaluated the quality of sleep in pregnancy or have explored the relationship between sleep disturbances and maternal and perinatal outcomes. OBJECTIVES: Our objective was to examine the relationship between objectively assessed sleep duration, timing and continuity (measured via wrist actigraphy) and maternal cardiovascular and metabolic morbidity specific to pregnancy...

RATIONALE: Methamphetamine is one of the most largely consumed illicit drugs, and its use is associated with abuse liability and several adverse health effects, such as sleep impairment. Importantly, sleep quality can influence addiction treatment outcomes. Evidence suggests that tolerance can develop to the sleep-disrupting effects of stimulant drugs. OBJECTIVE: The aim of the present study was to investigate the development of tolerance to the actigraphy-based sleep-disrupting and stimulant effects of methamphetamine self-administration in rhesus monkeys...

A significant number of adolescents have been exposed to traumatic life events. However, knowledge about the specific sleep disturbance that occurs in individuals after trauma exposure is predominantly based on studies of adults. This study reports specific sleep disturbance in 42 survivors of the 2011 mass shooting at a youth summer camp on the Norwegian island Utøya, mean age = 20.91 years, SD = 2.32, 62.5% females. When compared with matched controls, significantly more survivors reported having sleep disturbances, 52...

BACKGROUND: COPD is a debilitating disease that affects patients' daily lives. One's daily physical activity (DPA) decreases due to multifactorial causes, and this decrease is correlated with a poor prognosis in COPD patients. Muscle wasting may at least be partly due to increased activity of the ubiquitin proteasome pathway and apoptosis. METHODS: This study investigated the relationships among DPA, circulating proteasome activity, and protein carbonyl in COPD patients and healthy subjects (HSs)...

Study Objectives: Sleep quality is associated with different aspects of psychopathology, but relatively little research has examined links between sleep quality and externalizing behaviors or callous-unemotional traits. We examined: (1) whether an association exists between sleep quality and externalizing behaviors; (2) whether anxiety mediates this association; (3) whether callous-unemotional traits are associated with sleep quality. Methods: Data from two studies were used...

Glucagon-like peptide 1 plays a role in glucose regulation. Sleep disturbances (obstructive sleep apnea, insufficient or poor sleep quality) have been shown to adversely affect glucose metabolism. This study aimed to explore the relationship between sleep and glucagon-like peptide 1 regulation in patients with abnormal glucose tolerance. Seventy-one adults with haemoglobin A1c levels between 5.7% and < 6.5% and no history of diabetes participated. Habitual sleep duration and efficiency were obtained from 7-day actigraphy recordings...
