Nicola Cellini
In recent years sleep-related memory consolidation has become a central topic in the sleep research field. Several studies have shown that in healthy individuals sleep promotes memory consolidation. Notwithstanding this, the consequences of sleep disorders on offline memory consolidation remain poorly investigated. Research studies indicate that patients with insomnia, obstructive sleep apnea, and narcolepsy often exhibit sleep-related impairment in the consolidation of declarative and procedural information...

Delayed sleep phase disorder (DSPD) is common among adolescents and further increases their susceptibility to chronic sleep restriction and associated detrimental outcomes, including increased risk of depression, drug and alcohol use, behavioral problems, and poor scholastic performance. DSPD is characterized by sleep onset that occurs significantly later than desired bedtimes and societal norms. Individuals with DSPD exhibit long sleep latencies when attempting to sleep at conventional bedtimes. Circadian sleep disorders such as DSPD can occur when there is misalignment between sleep timing and societal norms...

BACKGROUND: Physical activity level is an important tool to identify individuals predisposed to developing chronic diseases, which represent a major concern worldwide. OBJECTIVE: To identify correlates of daily step counts measured using pedometers, as well as analyze the associations between health outcomes and three different amounts of daily physical activity. METHODS: The sample comprised 278 participants with a mean age of 46.51±9.02 years, of both sexes (126 men and 153 women)...

REVIEW
Shona L Halson
Sleep has numerous important physiological and cognitive functions that may be particularly important to elite athletes. Recent evidence, as well as anecdotal information, suggests that athletes may experience a reduced quality and/or quantity of sleep. Sleep deprivation can have significant effects on athletic performance, especially submaximal, prolonged exercise. Compromised sleep may also influence learning, memory, cognition, pain perception, immunity and inflammation. Furthermore, changes in glucose metabolism and neuroendocrine function as a result of chronic, partial sleep deprivation may result in alterations in carbohydrate metabolism, appetite, food intake and protein synthesis...

Many patients suffering from the majority of anxiety disorders complain about their sleep by reporting difficulties in initiating and maintaining it. Polysomnographic studies have shown that, in comparison to normal subjects, the sleep of patients with panic disorder is characterized by longer sleep latency, increased time awake and reduced sleep efficiency. Sleep architecture is normal and there are no significant changes in REM sleep measures. Nocturnal panic attacks are non-REM-related events and occur without an obvious trigger in 18-45% of panic disorder patients...

REVIEW
Megan E Petrov, Kenneth L Lichstein
Meta-analyses and other previous reviews have identified distinct ethnic/racial differences in the quantity, quality, and propensity for sleep disorders between black and white adults. The present article reviews the meta-analytic evidence along with recent epidemiological, community, and clinical studies to clarify what is known and not known about sleep differences between these two groups. Black individuals tend to have poorer sleep continuity and quality, excessively short or long sleep duration, greater sleep variability, and greater risk of sleep apnea than white individuals...

Short sleep duration is increasingly recognized as a risk factor for obesity. Sleep is now considered 1 of the 3 lifestyle behaviors, along with diet and exercise, which are closely associated with health. If sleep duration is a causal factor in the etiology of obesity, it must affect energy intake and/or energy expenditure to create a positive energy balance. The preponderance of evidence to date points to an effect of sleep restriction on energy intake that exceeds the added energy costs of maintaining longer wakefulness...

BACKGROUND: The increased risk of obesity among short sleepers is most likely explained by increased energy intake. However, food intake could not only be altered quantitavely but also qualitatively. Therefore, we performed a correlational analysis on self-reported food intake and sleep in 51 students from Maastricht and surroundings. RESULTS: Students that slept longer had a lower caloric intake: ρ = -0.378, p = 0.006, the amount of calories consumed per minute awake remaining relatively stable...

In the last three decades the two-process model of sleep regulation has served as a major conceptual framework in sleep research. It has been applied widely in studies on fatigue and performance and to dissect individual differences in sleep regulation. The model posits that a homeostatic process (Process S) interacts with a process controlled by the circadian pacemaker (Process C), with time-courses derived from physiological and behavioural variables. The model simulates successfully the timing and intensity of sleep in diverse experimental protocols...

Sleep contributes importantly to energy homeostasis, and may impact hormones regulating appetite, such as leptin, an adipocyte-derived hormone. There is increasing evidence that sleep duration, and reduced rapid eye movement sleep, are linked to obesity. Leptin has central neural effects beyond modulation of appetite alone. As sleep is not a unifrom process, interactions between leptin and sleep stages including rapid eye movement sleep may play a role in the relationship between sleep and obesity. This study examined the relationship between serum leptin and rapid eye movement sleep in a sample of healthy adults...

REVIEW
Shawn D Youngstedt
Historically, perhaps no daytime behavior has been more closely associated with better sleep than exercise. The assumption that exercise promotes sleep has also been central to various hypotheses about the functions of sleep. Hypotheses that sleep serves an energy conservation function, a body tissue restitution function, or a temperature down-regulation function all have predicted a uniquely potent effect of exercise on sleep because no other stimulus elicits greater depletion of energy stores, tissue breakdown, or elevation of body temperature, respectively...

BACKGROUND: Patients often complain about insufficient sleep or chronic insomnia in the belief that they need 8 hours of sleep. Treatment strategies may be guided by what sleep durations predict optimal survival and whether insomnia might signal mortality risks. METHODS: In 1982, the Cancer Prevention Study II of the American Cancer Society asked participants about their sleep duration and frequency of insomnia. Cox proportional hazards survival models were computed to determine whether sleep duration or frequency of insomnia was associated with excess mortality up to 1988, controlling simultaneously for demographics, habits, health factors, and use of various medications...

This study sought to characterize the impact of sleep location (own sleeping environment vs. partner's sleeping environment), social setting (sleeping in pairs vs. sleeping alone), and sex on sleep. An experimental 2 x 2 (sleep location x social setting) within-subject design was employed with 15 young heterosexual couples. The results suggest that sleep location does not appear to have a strong and consistent effect on sleep quantity or quality. The social setting had a specific effect in heterosexual young men, who were found to sleep longer and rise later when cosleeping with their partner...

Most forms of suprathreshold sensory stimulation perturb sleep. In contrast, presentation of pure olfactory or mild trigeminal odorants does not lead to behavioral or physiological arousal. In fact, some odors promote objective and subjective measures of sleep quality in humans and rodents. The brain mechanisms underlying these sleep-protective properties of olfaction remain unclear. Slow oscillations in the electroencephalogram (EEG) are a marker of deep sleep, and K complexes (KCs) are an EEG marker of cortical response to sensory interference...

OBJECTIVE: To investigate the effects of objectively measured habitual sleep patterns on cardiac autonomic modulation (CAM) in a population-based sample of adolescents. METHODS: We used data from 421 adolescents who completed the follow-up examination in the Penn State Children Cohort study. CAM was assessed by heart rate (HR) variability (HRV) analysis of beat-to-beat normal R-R intervals from a 39-h electrocardiogram, on a 30-min basis. The HRV indices included frequency domain (HF, LF, and LF/HF ratio), and time domain (SDNN, RMSSD, and heart rate or HR) variables...

Alteration in cardiac autonomic activity during sleep is a common feature of sleep disorders. Diurnal sympathetic overactivity is a possible consequence and could contribute to future cardiovascular complications. The aim of this study is to assess the relationship between cardiac autonomic activity during sleep and diurnal autonomic cardiovascular control. In a large cohort (n = 1011) of subjects aged 65 years old (± 0.4) free of cardiac and cerebrovascular events and of sleep-related breathing disorders, we evaluated (cross-sectional study) the prevalence of unexpected alteration in sleep-related autonomic overactivity according to the presence of a cyclical nocturnal heart rate variability [quantified using the relative power spectral density of the very low-frequency band of the heart rate increment (VLFi%) from ECG Holter monitoring]...
