OBJECTIVE: Epidemiological and laboratory-based driving simulator studies have shown the detrimental impact of moderate, legal levels of alcohol consumption on driving performance in sleepy drivers. As less is known about the time course of decaying alcohol alongside performance impairment, our study examined impairment and recovery of performance alongside decaying levels of alcohol, with and without sleep restriction. METHODS: Sixteen healthy young males (18-27 years) underwent 4 counterbalanced conditions: Baseline, Alcohol (breath alcohol concentration [BrAC] < 0...

The objective of this review is to provide an overview of intermittent fasting regimens, summarize the evidence on the health benefits of intermittent fasting, and discuss physiological mechanisms by which intermittent fasting might lead to improved health outcomes. A MEDLINE search was performed using PubMed and the terms "intermittent fasting," "fasting," "time-restricted feeding," and "food timing." Modified fasting regimens appear to promote weight loss and may improve metabolic health. Several lines of evidence also support the hypothesis that eating patterns that reduce or eliminate nighttime eating and prolong nightly fasting intervals may result in sustained improvements in human health...

In today's 24/7 society, sleep restriction is a common phenomenon which leads to increased levels of sleep pressure in daily life. However, the magnitude and extent of impairment of brain functioning due to increased sleep pressure is still not completely understood. Resting state network (RSN) analyses have become increasingly popular because they allow us to investigate brain activity patterns in the absence of a specific task and to identify changes under different levels of vigilance (e.g. due to increased sleep pressure)...

Shiftworkers are exposed to several adverse health conditions, one being eating at night. Food consumption at an unnatural time-of-day is thought to be one of the main factors responsible for the increased risk of developing metabolic diseases, such as obesity and diabetes mellitus. The underlying mechanism is considered to include disruption of the circadian organization of physiology, leading to disruption of metabolism. When food is consumed at night, the hypothalamus, a brain region central to homeostasis, receives contradicting input from the central clock and the systemic circulation...

BACKGROUND: According to recent studies, sleep restriction and disruption both have a prominent negative influence on glucose metabolism. This could also be shown in sleep disorders, such as sleep apnea and the restless legs syndrome. However, similar studies regarding insomnia have not been that consistent, yet. Moreover, most previous studies did not include objective polysomnography (PSG) data. METHODS: Patients with primary insomnia (N = 17) and healthy controls (N = 15) were investigated using psychometric tests such as the Epworth Sleepiness Scale and the Pittsburgh sleep quality index (PSQI)...

Olfaction can increase the drive to eat and may partially explain the consistent increases in energy intake (EI) following sleep restriction. We investigated the effects of 50% sleep restriction with altered sleep timing on olfactory performance. We also evaluated whether changes (Δ) in olfactory performance were associated with Δ24 h EI. Twelve men and six women (age: 23±4 years; BMI: 23±3 kg/m(2)) completed three randomized cross-over conditions: habitual sleep duration, 50% sleep restriction with advanced wake-time, and 50% sleep restriction with delayed bedtime...

Although non-invasive ventilation (NIV) has been used since the 1960's in the polio epidemic, the development of modern bilevel PAP devices did not become a reality until the 1990's. Over the last 25 years bilevel PAP technology options have exponentially increased. The number of patients receiving this treatment both in the acute setting as well as at home is steadily growing. However, a knowledge gap exists in the way these device settings are adjusted to achieve synchrony and match patient's unique respiratory failure physiology...

Snoring, chronic rhinitis and fragmentation of sleep are common symptoms in pregnancy, especially in the third trimester. The prevalence of obstructive sleep apnea is also increased in pregnant women and can be associated with pregnancy induced hypertension, preeclampsia and diabetes mellitus. The fetus is as well exposed to a higher risk of prematurity and intra-uterine growth restriction. Given the lack of adequate screening tool, the diagnosis of obstructive sleep apnea is a challenge for the physician and a high degree of clinical suspicion is necessary in order to identify the patients at risk and propose an appropriate management...

Sleep is important for normative cognitive functioning. A single night of total sleep deprivation can reduce the capacity to encode new memories. However, it is unclear how sleep restriction during several consecutive nights affects memory encoding. To explore this, we employed a parallel-group design with 59 adolescents randomized into sleep-restricted (SR) and control groups. Both groups were afforded 9 h time in bed (TIB) for 2 baseline nights, followed by 5 consecutive nights of 5 h TIB for the SR group (n = 29) and 9 h TIB for the control group (n = 30)...

In a previous case report, we determined for the first time that uvulopalatopharyngoplasty (UPPP) does not change the volume of the upper airway but causes morphological changes in the entire upper airway. The objective of this study is to elucidate the mechanisms underlying the improvement in obstructive sleep apnea syndrome (OSAS) by UPPP. We present an additional case involving a patient with OSAS treated using UPPP. Morphological and numerical parameter changes after surgery were compared with the corresponding preoperative values...

Stress fractures can be seen as an undesired byproduct of demanding physical training. The threshold value of stress that places an individual bone at high risk for stress fracture has not been identified. In a prospective study of stress fractures in 1983, a 31% incidence was found during demanding Israeli infantry basic training by bone scan criteria. Within a subgroup of these recruits, an elite infantry unit was found to have a 40% incidence. Since then and until 2015, eight additional induction companies of the same elite infantry unit were prospectively monitored for stress fractures during their basic training...

The raccoon dog (Nyctereutes procyonoides) is an invasive canid originating from eastern Asia. Here, we review its physiological adaptations to wintering, with an emphasis on northern Europe, where the raccoon dog spends the coldest part of the year in winter sleep. The timing of physiological changes related to wintering is connected to photoperiod by melatonin. In preparation to winter, raccoon dogs display autumnal hyperphagia and fattening probably regulated by the interaction of several peptide hormones...

OBJECTIVE: In times of the ubiquitous debate about doctors' working hour restrictions, it is still questionable if the physician's performance is impaired by high workload and long shifts. In this study we evaluated the impact of sleep interruption on the neurosurgical performance. METHODS: Ten medical students and ten neurosurgical residents were tested on the virtual-reality simulator NeuroTouch by performing the identical microsurgical task, well-rested (baseline test), and after sleep interruption at night (stress test)...

Obstructive sleep apnoea (OSA) is associated with increased cardiovascular disease (CVD) morbidity and mortality. It is accepted that OSA and obesity commonly coexist. The American Academy of Sleep Medicine recommends dietary-induced weight loss and exercise as lifestyle treatment options for OSA. However, most clinical trials upon which this recommendation is based have focused on establishing the effectiveness of calorie-restricted, often low-fat diets for improving OSA severity, whereas less attention has been given to the means through which weight loss is achieved (e...

Chronic sleep restriction is a common experience; and while it has negative physiological effects, little is known about how it affects human behavior. To date, no study has investigated whether chronic sleep restriction can influence implicit attitudes (e.g., towards a race). Here, in a randomized, counterbalanced crossover design, we subjected participants to 3 weeks of chronic sleep restriction in the lab (i.e., 3 weekly cycles of 5 nights of 4 hours of sleep per night followed by 2 nights of 8 hours of sleep) and found evidence for an increased negative implicit bias towards Arab Muslims...

Disturbance of rapid eye movement (REM) sleep appears early in both patients with Huntington's disease (HD) and mouse models of HD. Selective serotonin reuptake inhibitors are widely prescribed for patients with HD, and are also known to suppress REM sleep in healthy subjects. To test whether selective serotonin reuptake inhibitors can correct abnormal REM sleep and sleep-dependent brain oscillations in HD mice, we treated wild-type and symptomatic R6/2 mice acutely with vehicle and paroxetine (5, 10, and 20 mg/kg)...
