Study Objective: No studies have investigated sequential changes in the heart on MRI, along with observation of functional lung phenotypes and genetics, over the duration of chronic intermittent hypoxia (CIH). We investigated chronological changes in heart and lung phenotypes after CIH using a mouse model to provide new insights into the pathophysiology of sleep apnea-induced cardiovascular disease. Methods: C57BL/6J adult male mice were randomized to 4 weeks or 8 weeks of CIH...

Study Objectives: We tested the hypothesis that estradiol (E2) protects against cardio-respiratory disorders and oxidative stress induced by chronic intermittent hypoxia (CIH) in adult female rats. Methods: Sprague-Dawley female rats (230-250g) were ovariectomized (OVX) and implanted with osmotic pumps delivering vehicle (Veh) or E2 (0.5 mg/kg/day). After 14 days of recovery, the rats were exposed to chronic CIH (21%-10% O2 - 8 hours/day - 10 cycles/hour) or room air (RA)...

Study Objectives: Experimental evidence suggests that restorative processes depend on synaptic plasticity changes in the brain during sleep. We used the expression of plasticity-related genes to assess synaptic plasticity changes during drug-induced sleep. Methods: We first characterized sleep induced by eszopiclone in mice during baseline conditions and during the recovery from sleep deprivation. We then compared the expression of 18 genes and 2 miRNAs critically involved in synaptic plasticity in these mice...

Objectives: Daytime sleepiness is a significant public health concern. Early evidence points towards the computerized VIGALL (Vigilance Algorithm Leipzig) as time-efficient tool to assess sleepiness objectively. In the present study, we investigated the association between VIGALL variables of EEG-vigilance (indicating brain arousal in resting state) and subjective daytime sleepiness in the LIFE cohort study. Additionally, we validated VIGALL against the self-rated likelihood of having fallen asleep during the conducted resting EEG and against heart periods...

Study Objectives: Sleep quality is associated with different aspects of psychopathology, but relatively little research has examined links between sleep quality and externalizing behaviors or callous-unemotional traits. We examined: (1) whether an association exists between sleep quality and externalizing behaviors; (2) whether anxiety mediates this association; (3) whether callous-unemotional traits are associated with sleep quality. Methods: Data from two studies were used...

Study Objectives: To examine and compare the arousability threshold and fall risk upon awakening of doxepin (6 mg) versus zolpidem (10 mg). Methods: A total of 52 healthy adult males were included in a double-blind, placebo-controlled, 4-way crossover study. The experimental procedure included four nights with polysomnography in the lab (zolpidem, doxepin, and their respective placebo conditions). Arousability was measured using an auditory awakening threshold delivered at the peak-plasma concentration for the active hypnotics and at matched times for the respective placebo conditions...

Dysregulation of sleep is associated with metabolic diseases, and metabolic rate is acutely regulated by sleep-wake behavior. In humans and rodent models, sleep loss is associated with obesity, reduced metabolic rate, and negative energy balance, yet little is known about the neural mechanisms governing interactions between sleep and metabolism. We have developed a system to simultaneously measure sleep and metabolic rate in individual Drosophila, allowing for interrogation of neural systems governing interactions between sleep and metabolic rate...

Study Objectives: Social isolation has a multitude of negative consequences on human health including the ability to endure challenges to the immune system, sleep amount and efficiency, and general morbidity and mortality. These adverse health outcomes are conserved in other social species. In the fruit fly Drosophila melanogaster, social isolation leads to increased aggression, impaired memory and reduced amounts of daytime sleep. There is a correlation between molecules affected by social isolation and those implicated in sleep in Drosophila...

Study Objectives: Infants, children and adolescents are increasingly being prescribed continuous positive airway pressure (CPAP) for treatment of obstructive sleep apnea (OSAS), yet adherence is often poor. The purpose of this study was to examine the relationship between caregiver and patient-reported health cognitions about CPAP prior to starting CPAP, and CPAP adherence at one month. We hypothesized that greater caregiver-reported self-efficacy would be positively associated with CPAP adherence in children...

Study Objectives: This study examined whether sleep duration changes during the transition from full-time work to statutory retirement and, if this were the case, which pre-retirement factors, including sociodemographic, work, lifestyle and health factors, predict these changes. Methods: Data from repeated surveys of the Finnish Public Sector study, linked to records of retirement, were used. The study population consisted of 5,785 participants who retired on a statutory basis in 2000-2011 and who had responded to surveys on sleep duration at least once immediately before and after their retirement (mean number of repeat study waves 3...

Study Objectives: Upper airway surgery is often recommended to treat OSA patients who cannot tolerate continuous positive airways pressure (CPAP). However, the response to surgery is variable, potentially because it does not improve the non-anatomical factors (i.e. loop gain and arousal threshold) causing OSA. Measuring these traits clinically might predict responses to surgery. Our primary objective was to test the value of loop gain and arousal threshold to predict surgical success defined as 50% reduction in apnea-hypopnea index (AHI) and AHI <10 events/hr post-surgery...

Study objectives: Musculoskeletal pain is a major burden on society. Adults with sleep problems are at higher risk for musculoskeletal pain onset, but there is no evidence for this relationship in children and adolescents. This study aimed to systematically review prospective studies on the risk for musculoskeletal pain onset in children and adolescents with sleep problems. Methods: Five databases (MEDLINE, PsycINFO, AMED, EMBASE, HMIC) were systematically searched to identify prospective studies that investigated if children and adolescents (aged 6-19 years) with sleep problems are at higher risk for musculoskeletal pain onset...

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: To describe sleep duration patterns of adults over a 20-year period, to compare sociodemographic, lifestyle, and health characteristics across these patterns, and to relate the patterns to sleep quality. Methods: The study population consisted of 3,695 adults aged 20 to 59 years at baseline. Five measurements of self-reported sleep duration were used to compose seven patterns from 1987 to 2012: persistent short (≤6 hours), moderate (7-8 hours), or long (≥9 hours) sleep duration and several changing patterns (varying and became short, moderate, or long sleepers)...

Study Objectives: To determine if weekend catch-up sleep (CUS) impacts body mass index (BMI) in the general population. Methods: A stratified random sample (2,156 subjects; age 19-82 years old, 43.0±14.5; 1,183 male) from the general population was evaluated, in 2010, using face-to-face interviews about sociodemographic characteristics, height, weight, habitual sleep duration and time-in-bed at night on weekdays and weekend, sleep-related profiles, mood and anxiety scales, and comorbid-medical conditions...

Introduction: Impaired sleep has been reported as an important non-motor feature in dystonia, but so far, subjective complaints have never been compared with nocturnal video-polysomnographic recording, which is the gold standard to assess sleep-related disorders. Methods: Twenty patients with idiopathic isolated cervical dystonia and 22 healthy controls underwent extensive clinical investigations, neurological examination and questionnaires screening for excessive daytime sleepiness and sleep-related disorders...

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)...

Study Objectives: Sudden unexpected death during sleep (SUDS) is the most common cause of death in patients with familial dysautonomia, an autosomal recessive disease characterized by sensory and autonomic dysfunction. It remains unknown what causes SUDS in these patients and who is at highest risk. We tested the hypothesis that SUDS in FD is linked to sleep-disordered breathing. Methods: We retrospectively identified patients with familial dysautonomia who died suddenly and unexpectedly during sleep and had undergone polysomnography within the 18-month period prior to death...
