Obstructive sleep apnea syndrome is very prevalent in hypertensive subjects. Moreover, obstructive sleep apnea syndrome activates multiple processes that might be associated with silent cerebral infarct independently of established risk factors. Our aim is to estimate the frequency of obstructive sleep apnea syndrome in hypertensive patients with and without silent cerebral infarct, and to determine whether obstructive sleep apnea syndrome is an independent risk factor of silent cerebral infarct and/or lacunar silent cerebral infarct in patients with hypertension...

Objective From April 2008, specific health checkups have been implemented to prevent metabolic syndrome (MetS) and related cardiovascular diseases based on assurance of medical care for the elderly in Japan. In its "Standard Health Checkup and Counseling Guidance Program," 22 standard question items are recommended to assess health conditions of Japanese citizens. However, there are few community-based studies to clarify the relationship between question items and new onset of high risk conditions for cardiovascular diseases such as MetS...

BACKGROUND: The nature of the relationship between the non-medical use of prescription drugs (NMUPD) and suicide has not been clearly elucidated. Some studies have suggested that the relationship between substance use and suicidal ideation may be spurious and could be explained by other variables. METHODS: A school-based cross-sectional study was performed in Guangzhou. A total of 5853 students completed questionnaires and were included in the study. NMUPD, alcohol use, illicit drug use, depressive symptoms, sleep quality, and suicidal behaviors were assessed...

REVIEW
Zhengqing Zhao, Xiangxiang Zhao, Sigrid C Veasey
Approximately one-third of adolescents and adults in developed countries regularly experience insufficient sleep across the school and/or work week interspersed with weekend catch up sleep. This common practice of weekend recovery sleep reduces subjective sleepiness, yet recent studies demonstrate that one weekend of recovery sleep may not be sufficient in all persons to fully reverse all neurobehavioral impairments observed with chronic sleep loss, particularly vigilance. Moreover, recent studies in animal models demonstrate persistent injury to and loss of specific neuron types in response to chronic short sleep (CSS) with lasting effects on sleep/wake patterns...

Associations between sleep disordered breathing (SDB) and cardiometabolic outcomes have not been examined in highlanders.We performed nocturnal polygraphy in Peruvian highlanders (3825 m). Multivariable linear regression models examined associations between SDB metrics and haemoglobin, glucose tolerance (haemoglobin A1c (HbA1c)), fasting glucose, homeostatic model-based assessments of insulin resistance and β-cell function (HOMA-IR and HOMA-β, respectively), blood pressure, and lipids, while adjusting for age, sex, body mass index (BMI) and wake oxygenation...

INTRODUCTION: Sleep is important to promote optimal health and avoid negative health outcomes. Short-duration and low-quality sleep may be more common and more detrimental among women compared with men. Identifying the determinants of behaviour is one of the first steps in designing effective interventions. To our knowledge, no systematic review has identified the individual, social and environmental determinants of sleep among adult women. METHODS AND ANALYSIS: Studies reporting data on adult women from 18 to 64 years of age will be included...

RATIONALE: Obstructive sleep apnea (OSA) has been postulated to contribute to idiopathic pulmonary fibrosis by promoting alveolar epithelial injury via tractional forces and intermittent hypoxia. OBJECTIVE: To determine whether OSA is associated with subclinical interstitial lung disease (ILD) and with biomarkers of alveolar epithelial injury and remodeling. METHODS: We performed cross-sectional analyses of 1,690 community-dwelling adults who underwent 15-channel in-home polysomnography and thoracic computed tomography (CT) imaging in the Multi-Ethnic Study of Atherosclerosis...

Accurate breath detection is crucial in sleep and respiratory physiology research and in several clinical settings. However, this process is technically challenging due to measurement and physiological artifacts and other factors such as variable leaks in the breathing circuit. Recently developed techniques to quantify the multiple causes of obstructive sleep apnea, require intermittent changes in airway pressure applied to a breathing mask. This presents an additional unique challenge for breath detection...

The association of irregular sleep schedules with circadian timing and academic performance has not been systematically examined. We studied 61 undergraduates for 30 days using sleep diaries, and quantified sleep regularity using a novel metric, the sleep regularity index (SRI). In the most and least regular quintiles, circadian phase and light exposure were assessed using salivary dim-light melatonin onset (DLMO) and wrist-worn photometry, respectively. DLMO occurred later (00:08 ± 1:54 vs. 21:32 ± 1:48; p < 0...

OBJECTIVE: We aimed to assess the measurement properties of the ten-item Major Depression Inventory when used on clinical suspicion in general practice by performing a Rasch analysis. METHODS: General practitioners asked consecutive persons to respond to the web-based Major Depression Inventory on clinical suspicion of depression. We included 22 practices and 245 persons. Rasch analysis was performed using RUMM2030 software. The Rasch model fit suggests that all items contribute to a single underlying trait (defined as internal construct validity)...

Objective: Extant literature has demonstrated that symptoms of postconcussive syndrome (PCS) persist well beyond the expected 3-month post-injury recovery period in a minority of individuals with mild traumatic brain injury (mTBI). Suboptimal performance on validity measures and pre- and post-injury psychosocial stressors - rather than actual mTBI or current cognitive functioning - have been identified as predictors of chronic PCS. Whether premorbid IQ has any influence on chronic PCS has been understudied, in the context of established psychogenic etiologies...

BACKGROUND: Intermittent hypoxia (IH) induces activation of the integrated stress response (ISR), but its role in IH-induced visceral white adipose tissue (vWAT) insulin resistance in unknown. CHOP is activated by chronic ISR, while GADD34 dephosphorylates the subunit of translation initiation factor 2 (eIF2α), leading to termination of ISR. We hypothesized that CHOP/Gadd34 null mice would not manifest evidence of insulin resistance following IH exposures. METHODS: 8-week-old CHOP/GADD34-/- (DM) and wild type (WT) littermates were randomly assigned to IH or RA exposures for 6 weeks...

Poor sleep quality and inadequate sleep in adolescents are a rising trend globally. The Theory of Planned Behaviour (TPB)-which centres on an individual's attitude toward performing the behaviour, subjective norms and perceived behavioural control-has been applied to examine sleep hygiene behaviours in young adults. We expanded on prior works by using a longitudinal design to examine the effects of TPB factors, together with sleep hygiene knowledge and planning constructs, on sleep hygiene behaviours and on sleep quality and health in a group of Iranian adolescents...

The present study aimed to investigate the efficacy of adenotonsillectomy (AT) for children with obstructive sleep apnea syndrome (OSAS) and the improvement of their cognitive function. Studies on cognitive performance of OSAS children treated with or without AT were identified by searching the Pubmed, EMBASE and Cochrane library. A meta-analysis was conducted to analyze the literature. The random-effects model was used to evaluate 11 eligible studies using an inverse- variance method. The neuropsychological test results of 4 cognitive domains (general intelligence, memory, attention-executive function and verbal ability) were obtained and analyzed...
