Insomnia is considered a hyperarousal disorder, in which several psychophysiological domains including the autonomic nervous system (ANS) are over-activated, potentially contributing to increased risk for cardiovascular (CV) disease. Here, we aimed to determine whether insomnia that develops in the context of the transition to menopause (menopausal transition insomnia, MTI) is similarly characterized by autonomic arousal. We also took into account modulation of the ANS by the hormonal changes of the menstrual cycle, a factor that has not previously been considered in studies on insomnia...

BACKGROUND: Insomnia is a robust correlate of suicidal ideation and behavior. Preliminary research has identified thwarted belongingness (c.f. social disconnection) as an explanatory link between insomnia and suicidal ideation. OBJECTIVES: This study replicates and extends previous findings using both cross-sectional and longitudinal designs in four demographically diverse samples. Additionally, the specificity of thwarted belongingness was evaluated by testing anxiety as a rival mediator...

The interaction between different brain structures could be crucial to predicting seizure occurrence, threshold and spread. Moreover, the sleep-wake cycle and electrical activity of brain structures in different phases of sleep could significantly affect the pattern and extent of seizure spread, and therefore the characteristics of epileptic activity. In this animal model using 15 Wistar rats, we show that the duration of hippocampal seizures, induced by electrical stimulation of the hippocampus, is significantly increased during slow sleep...

Rapid eye movement sleep behavior disorder (RBD) is thought to be one of the most frequent preceding symptoms of Parkinson's disease (PD). However, the prevalence of RBD in PD stated in the published studies is still inconsistent. We conducted a meta and meta-regression analysis in this paper to estimate the pooled prevalence. We searched the electronic databases of PubMed, ScienceDirect, EMBASE and EBSCO up to June 2016 for related articles. STATA 12.0 statistics software was used to calculate the available data from each research...

PURPOSE: Obstructive sleep apnoea (OSA) is a prevalent disorder, characterised by collapse of the upper airways during sleep. The impact of sleep-disordered breathing on pulmonary function indices is however currently not well described. The aim of the study was to evaluate diurnal change in lung function indices in a cohort of patients with OSA and relate pulmonary function changes to disease severity. METHODS: 42 patients with OSA and 73 healthy control subjects participated in the study...

Obesity is among the leading risk factors for obstructive sleep apnea (OSA). A reciprocal relationship between obesity and OSA has been proposed, which may be due to excessive food intake. We conducted a pilot study to test the effects of continuous positive airway pressure (CPAP) on energy intake (EI) in OSA patients using a sham-controlled crossover design. In-laboratory total daily EI was assessed after 2mo of active and sham CPAP. Four men were enrolled (age±SEM: 51.8±2.1y; body mass index: 31.5±1.5kg/m(2))...

BACKGROUND: Although sleep is considered an essential part of individuals' lives, there are no previous studies analysing how sleep duration affects the levels of life satisfaction reported by males and females with disabilities. OBJECTIVE/HYPOTHESIS: To analyse and compare the impact of hours of sleep on life satisfaction scores reported by people without and with disabilities (stratified by sex) in Germany. METHODS: Using data taken from the German Socio-Economic Panel for the period 2008-2013, we estimate life satisfaction equations for males and females (running a fixed-effects model) which include a set of variables measuring the number of sleep hours on workdays and weekends...

Pannexins are membrane channel proteins that play a role in a number of critical biological processes (Panchin et al., 2000; Shestopalov, Panchin, 2008). Among other cellular functions, pannexin hemichannels serve as purine nucleoside conduits providing ATP efflux into the extracellular space (Dahl, 2015), where it is rapidly degraded to adenosine. Pannexin1 (Panx1) is abundantly expressed in the brain and has been shown to contribute to adenosine signaling in nervous system tissues (Prochnow, 2012)...

Obesity, along with hypertrophy of the adenoids and the tonsils, represents one of the major risk factors for obstructive sleep apnea (OSA) in children. Obesity is associated with an increase in the prevalence and the severity of OSA and is a major factor in the persistence and aggravation of OSA over time. Neurocognitive dysfunction and abnormal behavior are the most important and frequent end-organ morbidities associated with OSA in children. Other deleterious consequences such as cardiovascular stress and metabolic syndrome are less common in children than in adults with OSA...

The French Society of Research and Sleep Medicine (SFRMS) organized a meeting on obstructive sleep apnea syndrome (OSAS) in children. A multidisciplinary group of specialists (pulmonologist, ENT surgeons, pediatricians, orofacial myofunctional therapists, neurophysiologists, and sleep specialists) reached a consensus on the value of isolated or clustered clinical symptoms and of questionnaires completed by parents in the clinical diagnosis and in assessing the severity of OSAS. Are clinical history with validated questionnaires and a rigorous physical examination sufficient to suspect OSAS, to appreciate its severity, and finally to confirm the diagnosis? Usually, a sleep recording of respiratory parameters remains mandatory for the diagnosis of OSAS to be made...

Attention deficit hyperactivity disorder (ADHD) is a common disorder, often associated with sleep disorders. Patients with primary sleep disorders often present hyperactivity and/or attention deficit symptoms. Indeed, obstructive sleep disorder breathing (snoring, hypoventilation disorder, and obstructive sleep apnea syndrome) with poor sleep quality can mimic ADHD in children. In this case, inattention and hyperactivity behavior are induced by sleep disorders but do not constitute a clinical diagnosis of ADHD...

BACKGROUND: Most children in Western populations do not meet recommendations for fish consumption. Oily fish is an important source of n-3 long-chain polyunsaturated fatty acids (LCPUFA), which reduce blood pressure and plasma triacylglycerol in adults and may affect cognitive development and behavior. However, to our knowledge, the potential effects of oily fish on cardiometabolic health, cognitive function, and behavior in children have not been investigated. The aim of the FiSK Junior study is to investigate the effects of oily fish consumption on cardiovascular risk markers, cognitive function, and behavior in healthy children...

BACKGROUND: A disturbed circadian rhythm seems to be a causal factor in the occurrence of depressive disorders in patients with Parkinson's disease (PD). The circadian rhythm can be restored with light. Therefore, Bright Light Therapy (BLT) might be a new treatment option for depression in PD patients. METHODS/DESIGN: In this double-blind controlled trial, 84 subjects with idiopathic PD are randomized to either BLT or a control light condition. The BLT condition emits white light with an intensity of 10,000 Lux, while the control device emits dim white light of 200 Lux, which is presumed to be too low to influence the circadian rhythm...

Infant mortality rate is generally regarded as a fundamental indicator of population health and is often used to validate public health interventions. Hamilton County, Ohio, has one of the highest rates in the nation. Most deaths that do not occur in the hospital fall under the jurisdiction of a coroner/medical examiner. We reviewed all infant deaths evaluated by the Hamilton County Coroner from 2006 to 2013 in order to identify opportunities for public health interventions. We predicted that the majority of these infant deaths were unintentional, but preventable...

RATIONALE: Prior research found that individual-level environmental and social indicators did not explain the racial disparity in obstructive sleep apnea syndrome. Neighborhood socioeconomic variables, risk factors for a range of adverse behavioral and health outcomes, may better explain this racial disparity and help identify modifiable intervention targets. OBJECTIVES: To evaluate the associations of neighborhood socioeconomic variables with obstructive sleep apnea severity and to assess whether the neighborhood variables explain the association between race and obstructive sleep apnea severity...
