BACKGROUND: The psychomotor vigilance task (PVT) has been widely used to assess the effects of sleep deprivation on human neurobehavioral performance. To facilitate research in this field, we previously developed the PC-PVT, a freely available software system analogous to the "gold-standard" PVT-192 that, in addition to allowing for simple visual reaction time (RT) tests, also allows for near real-time PVT analysis, predictions, and visualization in a personal computer (PC)...

INTRODUCTION: Delirium, which is prevalent in postcardiac surgical patients, is an acute brain dysfunction characterised by disturbances in attention, awareness and cognition not explained by a pre-existing neurocognitive disorder. The pathophysiology of delirium remains poorly understood. However, basic science and clinical studies suggest that sleep disturbance may be a modifiable risk factor for the development of delirium. Dexmedetomidine is a α-2A adrenergic receptor agonist medication that patterns the activity of various arousal nuclei similar to sleep...

The retrotrapezoid nucleus (RTN) is one of several CNS nuclei that contribute, in various capacities (e.g. CO2 detection, neuronal modulation) to the central respiratory chemoreflex (CRC). Here we test how important the RTN is to PCO2 homeostasis and breathing during sleep or wake. RTN Nmb positive neurons were killed with targeted microinjections of substance-P-saporin conjugate in adult rats. Under normoxia, rats with large RTN lesions (92 ± 4 % cell loss) had normal blood pressure (BP) and arterial pH but were hypoxic (-8 mmHg PaO2 ) and hypercapnic (+10 mmHg PaCO2 )...

Individuals with more or stronger social bonds experience enhanced survival and reproduction in various species, though the mechanisms mediating these effects are unclear. Social thermoregulation is a common behaviour across many species which reduces cold stress exposure, body heat loss, and homeostatic energy costs, allowing greater energetic investment in growth, reproduction, and survival, with larger aggregations providing greater benefits. If more social individuals form larger thermoregulation aggregations due to having more potential partners, this would provide a direct link between sociality and fitness...

CONTEXT: The loss of progesterone during menopause is linked to sleep complaints of the affected women. Previously we demonstrated sleep promoting effects of oral progesterone replacement in postmenopausal women. The oral administration of progesterone, however, is compromised by individual differences in bioavailability and metabolism of the steroid. OBJECTIVE: We compared the sleep-endocrine effects after intranasal progesterone (MPP22), zolpidem and placebo in healthy postmenopausal women...

Modafinil is primarily prescribed for treatment of narcolepsy and other sleep-associated disorders. However, its off-prescription use as a cognition enhancer increased considerably, specially among youths. Given its increasing use in young adults the effect of modafinil on peak bone accrual is an important issue but has never been investigated. Modafinil treatment to young male rats caused trabecular and cortical bone loss in tibia and femur, and reduction in biomechanical strength. Co-treatment of modafinil with alendronate (a drug that suppresses bone resorption) reversed the trabecular bone loss but failed to prevent cortical loss...

Clinico-pathological studies that focus on sudden unexpected death (SUD) in the neonatal period are rare. The objective of this study was to elucidate the frequency and pathological spectrum of anatomical causes of death (CODs), found in the setting of sudden unexpected death in neonates (SUD-N), and to correlate the COD with premortem circumstantial information. We conducted a detailed review of all autopsy reports on SUD-N cases at our institution from 1997 to 2015. Analyzed clinical data included obstetrical history, postpartum/neonatal medical course, and circumstances surrounding death...

Sexually dimorphic phenotypes are a universal phenomenon in animals. In the model animal fruit fly Drosophila, males and females exhibit long- and short-sleep phenotypes, respectively. However, the mechanism is still a mystery. In this study, we showed that juvenile hormone (JH) is involved in regulation of sexually dimorphic sleep in Drosophila, in which gain of JH function enlarges differences of the dimorphic sleep phenotype with higher sleep in males and lower sleep in females, while loss of JH function blurs these differences and results in feminization of male sleep and masculinization of female sleep...

PURPOSE: Bariatric surgery (BS) is a treatment option for morbid obesity leading to substantial and sustained weight loss in adults. As obstructive sleep apnea (OSA) is highly prevalent in obese subjects and may increase the perioperative risk, screening for OSA is recommended prior to BS. In clinical routine, BS is performed more frequently in women. Therefore, we sought to assess the gender-specific performance of four sleep questionnaires (Epworth Sleepiness Scale (ESS), Fatigue Severity Scale (FSS), STOPBang, and NoSAS) to predict moderate to severe OSA in the morbidly obese population...

REVIEW

Kleine-Levin syndrome (KLS) is a rare, relapsing-remitting disease that affects mostly adolescents. It is characterized by episodes lasting from 1 to several weeks, and comprises neurological (hypersomnia, confusion, slowness, amnesia) and neuropsychiatric symptoms (derealization and apathy). Some psychiatric symptoms (megaphagia, hypersexuality, anxiety, depressed mood, hallucinations, delusions) arise during episodes, albeit less frequently, while patients are normal between episodes. However, sudden severe (>18h/day of sleep) and recurrent hypersomnia helps to differentiate KLS from other psychiatric mimics...

OBJECTIVE: Auditory brainstem response (ABR) testing is the gold-standard procedure for hearing evaluation in pediatric patients who cannot complete a behavioral hearing test. The amount of audiological information obtained depends on the quality of the patient's sleep during the test. In this retrospective database review, we aimed to assess the amount and the characteristics of the audiological information obtained in ABR testing in pediatric patients with age-appropriate sedation. METHODS: A retrospective chart review was conducted on 501 consecutive ABR sedation sessions performed between January 2014 and June 2016 at the Tel Aviv Medical Center...
