BACKGROUND: Obstructive sleep apnea (OSA) is associated with changes in pharyngeal anatomy. The goal of this study was to objectively and reproducibly quantify pharyngeal anatomy using digital morphometrics based on a laser ruler, and to assess differences between apneics and controls and associations with AHI (apnea-hypopnea index). This is the first study to use digital morphometrics to quantify intraoral risk factors for OSA. METHODS: Digital photographs were obtained using an intraoral laser ruler and digital camera in 311 controls (mean AHI=4...

Brain histamine acts as a neurotransmitter and regulates various physiological functions, such as learning and memory, sleep-wake cycles, and appetite regulation. We have recently shown that histamine H3 receptor (H3R) is expressed in primary mouse microglia and has a strong influence on critical functions in microglia, including chemotaxis, phagocytosis, and cytokine secretion in vitro. However, the importance of H3R in microglial activity in vivo remains unknown. Here, we examined the effects of JNJ10181457 (JNJ), a selective and potent H3R inverse agonist, on microglial functions ex vivo and in vivo...

INTRODUCTION: Many adults experience poor sleep quality, and personality traits have emerged as important predictors of self-reported sleep. However, it is still unclear whether personality predicts sleep quality independent of other correlates, including mood, emotion regulation, and hyperarousal. AIMS AND METHOD: The aim of this study was twofold. First, using an online survey, we assessed the relationship between perceived sleep quality (defined here as the total score of the Pittsburgh Sleep Quality Index) and personality in 498 Italians (M age=26...

BACKGROUND: Insomnia symptoms are prevalent and associated with impaired health and well-being. However, scant research has investigated whether midlife insomnia symptoms are also associated with earlier retirement, thereby contributing to additional economic consequences. PARTICIPANTS AND METHODS: We analyzed data from a community-based sample of 1635 Wisconsin State employees (51.6% women) that were collected from 1988 until 2014. Study participants were asked about insomnia symptoms (difficulty getting to sleep, difficulty getting back to sleep, repeated nocturnal awakenings, and early morning awakenings) in midlife, with prospective follow-up questions about the specific reasons for retirement between 2010 and 2014...

Study Objectives: Menopausal transition is associated with increased dissatisfaction with sleep, but the effects on sleep architecture are conflicting. This prospective six-year follow-up study was designed to evaluate the changes in sleep stages and sleep continuity that occur in women during menopausal transition. Methods: Sixty women (mean age 46.0 years, SD 0.9) participated. All women were premenopausal at baseline, and at the six-year follow-up, women were in different stages of menopausal transition...

Study objectives: We conceptualised sleep quality judgement as a decision-making process and examined the relative importance of 17 parameters of sleep quality using a choice-based conjoint analysis. Methods: 100 participants (50 good sleepers; 50 poor sleepers) were asked to choose between two written scenarios to answer one of two questions: "Which describes a better (or worse) night of sleep?". Each scenario described a subjective experience of sleep, stringing together 17 possible determinants of sleep quality that occur at different times of the day (day before, pre-sleep, during sleep, upon waking, day after)...

The mechanisms by which the work environment might influence cardiovascular risk are still a matter of debate. In particular, the involvement of the main behavioral and clinical risk factors and their relationships with working conditions are not always clear despite an abundant literature. Most studies have investigated the impact of a limited number of characteristics of the work environment on the occurrence of one or a few risk factors. In contrast, this study uses a global approach in which 30 objective and subjective indicators of working conditions are tested as predictors of 9 modifiable cardiovascular risk factors in a well-characterized cohort of 20,625 middle-aged French workers who were followed until they retired...

Microglia are the resident immune cells of the central nervous system (CNS) and they contribute to primary inflammatory responses following CNS injuries. The morphology of microglia is closely associated with their functional activities. Most previous research efforts have attempted to delineate the role of ramified and amoeboid microglia in the pathogenesis of neurodegenerative diseases. In addition to ramified and amoeboid microglia, bipolar/rod-shaped microglia were first described by Franz Nissl in 1899 and their presence in the brain was closely associated with the pathology of infectious diseases and sleeping disorders...

STUDY OBJECTIVES: The study aimed to compare urinary biomarkers in patients with Down syndrome (DS) with and without obstructive sleep apnea (OSA) to those of age- and sex-matched neurotypically developing healthy controls (HC). We further investigated whether we could predict OSA in patients with DS using these biomarkers. METHODS: Urine samples were collected from 58 patients with DS the night before or the morning after their scheduled overnight polysomnogram or both, of whom 47 could be age- and sex-matched to a sample of 43 HC...

BACKGROUND: Associations between sleep duration and cardiovascular conditions have been inconsistent. Both short and long sleep duration are associated with increased risk for diabetes, hypertension, obesity, high cholesterol, depression, and overall metabolic dysfunction; all of which are cardiovascular disease risk factors. This study aimed to determine if deficient or excessive sleep duration is associated with cardiovascular conditions. METHODS: Data were obtained from the 2013 Behavioral Risk Factor Surveillance System for the state of Nevada...

BACKGROUND: Sleep-disordered breathing (SDB) is often co-morbid with conductive hearing loss in early childhood due to a shared aetiology of adenotonsillar hypertrophy. Hearing loss is independently associated with impairment of executive function and behavioural difficulties. We hypothesised that these impairments in children with SDB may be mediated through hearing loss. METHODS: Fifty-eight children including 37 snorers awaiting adenotonsillectomy and 21 healthy non-snoring controls, aged 3-5 years, were assessed with pure tone audiometry, Strengths and Difficulties (SDQ), Behaviour Rating of Executive Function (BRIEF-P), and Childhood Middle Ear Disease and Hearing questionnaires...

OBJECTIVE: Primary snoring (PS) and obstructive sleep apnea (OSA) not only affect the quality of sleep in a large number of young children, but have also been repeatedly associated with a variety of behavioral and cognitive problems. However, little is known about the potentially differing relationships of behavioral and cognitive pathology within the sleep disordered breathing (SDB) spectrum. METHOD: This study examined data from an enriched for snoring community sample of 631 children aged between 4 and 10 years...

OBJECTIVES: In older adults, traditional metrics derived from polysomnography (PSG) are not well correlated with subjective sleep quality. Little is known about whether the association between PSG and subjective sleep quality changes with age, or whether quantitative electroencephalography (qEEG) is associated with sleep quality. Therefore, we examined the relationship between subjective sleep quality and objective sleep characteristics (standard PSG and qEEG) across middle to older adulthood...

OBJECTIVE: Traumatic events, particularly those that are interpersonal in nature, are associated with increased risk for co-occurring sequelae, including sleep disturbances, posttraumatic stress disorder (PTSD), and alcohol use disorder (AUD). However, the associations between these phenotypes have not been explored among college students. METHODS: We examined relationships between type of potentially traumatic event (PTE) exposure (pre-college) and sleep disturbances, as well as mediating effects of lifetime PTSD and AUD symptoms on these relationships, in a large undergraduate sample (N = 1599, 64...

BACKGROUND: Associations between sleep duration and cardiovascular disease (CVD) risk factors have been demonstrated in past studies. However, previous studies have not investigated these relationships using objective sleep measures in sub-Saharan Africa. Our objective was to investigate the association between sleep duration and cardiovascular risk factors in a sample of community-dwelling Ghanaian adults. METHODS: We used wrist actigraphy along with a seven-day sleep diary to measure sleep duration, wake after sleep onset, sleep latency, and sleep quality...
