OBJECTIVE: We aimed to compared sleep characteristics associated with quick returns (QRs, <11 hours between shift intervals) with those associated with other common shift transitions. METHODS: Sixty-seven nurses completed a 2-week work and sleep diary (94.0% female, mean age 47.7 years). A multilevel fixed effects model was used to examine the sleep in QRs compared with two consecutive night shifts, two consecutive evening shifts, and two consecutive day shifts, respectively...

OBJECTIVES: Across age groups, bipolar disorder (BD) carries the greatest risk of death by suicide of all psychiatric conditions; 25%-50% of those with BD will make one or more suicide attempt. Psychometrically sound instruments are required to reliably measure suicide ideation and risk of self-harm for older adults with BD. For this study, we validate the geriatric suicide ideation scale (GSIS) with adults 50+ years with BD. METHODS: We recruited a global sample of 220 older adults with BD (M = 58...

Existing mathematical models for predicting neurobehavioural performance are not suited for mobile computing platforms because they cannot adapt model parameters automatically in real time to reflect individual differences in the effects of sleep loss. We used an extended Kalman filter to develop a computationally efficient algorithm that continually adapts the parameters of the recently developed Unified Model of Performance (UMP) to an individual. The algorithm accomplishes this in real time as new performance data for the individual become available...

BACKGROUND: Although stress during pregnancy has negative effects on children's development and pregnant women's health, no study has assessed stress and its predictors among pregnant Saudi women. The aim of this study was to assess stress and identify its predictors in a sample of pregnant Saudi women. METHODS: A correlational study was carried out at King Abdulaziz Medical City in Riyadh, Kingdom of Saudi Arabia, on 438 pregnant women who attended the obstetrics/gynecology clinic...

Parkinson's disease (PD) is more commonly associated with its motor symptoms and the related degeneration of dopamine (DA) neurons. However, it is becoming increasingly clear that PD patients also display a wide range of non-motor symptoms, including memory deficits and disruptions of their sleep-wake cycles. These have a large impact on their quality of life, and often precede the onset of motor symptoms, but their etiology is poorly understood. The fruit fly Drosophila has already been successfully used to model PD, and has been used extensively to study relevant non-motor behaviours in other contexts, but little attention has yet been paid to modelling non-motor symptoms of PD in this genetically tractable organism...

Sleep deprivation (SD) negatively impacts memory, which was related to oxidative stress induced damage. L-carnitine is a naturally occurring compound, synthesized endogenously in mammalian species and known to possess antioxidant properties. In this study, the effect of L-carnitine on learning and memory impairment induced by rapid eye movement sleep (REM-sleep) deprivation was investigated. REM-sleep deprivation was induced using modified multiple platform model (8hrs/day, for 6 weeks). Simultaneously, L-carnitine was administered (300mg/kg/day) intraperitoneally for 6 weeks...

The detailed molecular mechanisms underlying the regulation of sleep/wake cycles in mammals are elusive. In this regulation, at least two mechanisms with fast and slow time scales are involved. In the faster time scale, a state of non-rapid-eye-movement (NREM) sleep can be microscopically characterized by the millisecond-to-second-order electrical behavior of neurons, namely slow-wave oscillations described by electrophysiology. In the slower time scale, the total duration of NREM sleep is homeostatically regulated by sleep pressure (the need for sleep), which is usually sustained for hours or even days and can be macroscopically described by electroencephalogram (EEG)...

CONTEXT: Cancer treatment symptoms play a major role in determining the health of children with cancer. Symptom toxicity often results in complications, treatment delays, and therapy dose reductions that can compromise leukemia therapy and jeopardize chances for long-term survival. Critical to understanding symptom experiences during treatment is the need for exploration of "why" inter-individual symptom differences occur; this will determine who may be most susceptible to treatment toxicities...

BACKGROUND: Disclosure of the use of complementary health approaches (CHA) is an important yet understudied health behavior with important implications for patient care. Yet research into disclosure of CHA has been atheoretical and neglected the role of health beliefs. PURPOSE: Using a consumer commitment model of CHA use as a guiding conceptual framework, the current study tests the hypotheses that perceived positive CHA outcomes (utilitarian values) and positive CHA beliefs (symbolic values) are associated with disclosure of CHA to conventional care providers in a nationally representative US sample...

BACKGROUND: Patients suffering from depression have a high risk of relapse and readmission in the weeks following discharge from inpatient wards. Electronic self-monitoring systems that offer patient-communication features are now available to offer daily support to patients, but the usability, acceptability, and adherence to these systems has only been sparsely investigated. OBJECTIVE: We aim to test the usability, acceptability, adherence, and clinical outcome of a newly developed computer-based electronic self-assessment system (the Daybuilder system) in patients suffering from depression, in the period from discharge until commencing outpatient treatment in the Intensive Outpatient Unit for Affective Disorders...

While chronic systemic inflammation in obstructive sleep apnea (OSA) has been traditionally considered a consequence of intermittent hypoxia, several treatment studies targeting inflammation suggest that this process may precede the development of the disorder. A recent cross-sectional study in the Penn State Child Cohort (PSCC) revealed that inflammation largely mediates the association between visceral adiposity and OSA in adolescence. The purpose of this study was to examine for the first time whether, longitudinally, inflammation precedes OSA during this developmental period...

Primary caregivers for victims of chronic illness and or trauma experience both positive and negative emotional consequences. These are broadly classified as compassion satisfaction (CS) and compassion fatigue (CF). Because one of the components of CF, burnout, varies with chronotype and sleep quality, we assessed the influence of chronobiological features on the broader constructs of CS and CF. Responses from primary ambulatory care oncology staff working dayshifts were assessed for potential relationships of chronotype and sleep quality with CS and CF using the professional quality of life scale...

BACKGROUND: Pruritus is still a forgotten aspect of hidradenitis suppurativa (HS) and, to date, has never been adequately studied. OBJECTIVE: The aim of this study was to determine the prevalence, and explore the characteristics, of pruritus in a well-defined cohort of HS patients. SETTING: An academic hospital-based cross-sectional study in The Netherlands. METHODS: A numerical rating scale (NRS, 0-10) was used to determine the prevalence of HS-related itch (NRS score ≥3)...

PURPOSE: A growing number of longitudinal studies report associations between adverse psychosocial factors at work and sleep problems. However, the evidence regarding the direction of these associations and the effects of changes in exposure across time is limited. This study examined the plausibility of normal, reverse, and reciprocal associations between ten psychosocial factors at work and sleep problems. In addition, we analyzed if reduced exposure across time had the anticipated result of reducing the risk of sleep problems...

BACKGROUND: The patterns of mandibular movements (MM) during sleep can be used to identify increased respiratory effort periodic large-amplitude MM (LPM), and cortical arousals associated with "sharp" large-amplitude MM (SPM). We hypothesized that Cheyne Stokes breathing (CSB) may be identified by periodic abnormal MM patterns. The present study aims to evaluate prospectively the concordance between CSB detected by periodic MM and polysomnography (PSG) as gold-standard.

BACKGROUND: Socioeconomic status (SES) and lifestyle-related factors are determinants of subjective health. However, changes in SES are inevitable in times of natural disaster, while lifestyle-related factors remain modifiable. The aim of this study was to use a cross-sectional approach to examine lifestyle-related factors that may attenuate the negative impact of disaster-induced changes in SES on poor subjective health. METHODS: We analyzed 33,350 men and women aged 20-64 years who were living in evacuation zones due to the radiation accident in Fukushima, Japan...

The serotonergic system integrates sex steroid information and plays a central role in mood and stress regulation, cognition, appetite and sleep. This interplay may be critical for likelihood of developing depressive episodes, at least in a subgroup of sensitive individuals. The serotonin 4 receptor (5-HT4R) indexes central serotonergic tonus, which may be related to endogenous sex-steroid levels in the mentally healthy state even though this remains elusive. Here we evaluate if peripheral levels of estradiol and testosterone are associated with 5-HT4R binding as imaged by [(11)C]SB207145 positron emission tomography in a group of 41 healthy men...

OBJECTIVE: Emerging research demonstrates race differences in diurnal cortisol slope, an indicator of hypothalamic-pituitary-adrenocortical (HPA)-axis functioning associated with morbidity and mortality, with African Americans showing flatter diurnal slopes than their White counterparts. Sleep characteristics are associated with both race and with HPA-axis functioning. The present report examines whether sleep duration may account for race differences in cortisol dynamics. METHOD: Participants were 424 employed African American and White adults (mean age = 42...

BACKGROUND AND PURPOSE: New venues are currently being explored to predict disease progression in Parkinson's disease (PD), such as non-motor subtypes and models merging motor and non-motor symptoms (NMS). By involving a subgroup of 585 patients from the PRIAMO (Parkinson Disease Non-motor Symptoms) study, the present 24-month longitudinal prospective analysis aimed to demonstrate that urinary dysfunction is an early marker of higher motor and non-motor burden as well as lower health-related quality of life...

PURPOSE: The primary objective of this paper was to identify significant factors associated with positional Obstructive Sleep Apnea (POSA) and to provide a clinical tool for discriminating non positional from POSA. Secondary objectives were about estimating the prevalence of POSA, comparing the polysomnographic variables across POSA and non-POSA patients. METHODS: This was a cross sectional study on 278 patients who completed an overnight sleep study for OSA assessment...
