The Social Patterning of Sleep in African Americans: Associations of Socioeconomic Position and Neighborhood Characteristics with Sleep in the Jackson Heart Study
Conclusions:Social and environmental characteristics are associated with sleep duration and quality in African Americans. Depressive symptoms may explain at least part of this association.Citation:Johnson DA, Lisabeth L, Hickson D, Johnson-Lawrence V, Samdarshi T, Taylor H, Diez Roux AV. The social patterning of sleep in African Americans: associations of socioeconomic position and neighborhood characteristics with sleep in the Jackson Heart Study.SLEEP 2016;39(9):1749–1759.

Sleep Duration and White Matter Quality in Middle-Aged Adults
Conclusions:Short sleep duration was associated with worse markers of white matter integrity in midlife. These mid-life differences in white matter may underlie the link between poor sleep and risk of dementia and stroke.Citation:Yaffe K, Nasrallah I, Hoang TD, Lauderdale DS, Knutson KL, Carnethon MR, Launer LJ, Lewis CE, Sidney S.

The Evolution of REM Sleep Behavior Disorder in Early Parkinson Disease
Conclusions:RBD increased significantly in PD patients from the de novo state to two-year follow-up. We propose RBE being named“prodromal RBD” as it may follow a continuous evolution in PD possibly similar to the spreading of Lewy bodies in PD patients. RBD itself was shown as a robust and stable marker of early PD.Citation:Sixel-Döring F, Zimmermann J, Wegener A, Mollenhauer B, Trenkwalder C.

Spatiotemporal Organization and Cross-Frequency Coupling of Sleep Spindles in Primate Cerebral Cortex
Conclusions:Spindles in widespread cortical regions are possibly driven by independent rhythm generators, but are temporally associated to spindles in other regions and to slow and gamma oscillations by corticocortical and thalamocortical pathways.Citation:Takeuchi S, Murai R, Shimazu H, Isomura Y, Mima T, Tsujimoto T. Spatiotemporal organization and cross-frequency coupling of sleep spindles in primate cerebral cortex.SLEEP 2016;39(9):1719–1735. (Source: Sleep)

Onset of Impaired Sleep and Cardiovascular Disease Risk Factors: A Longitudinal Study
Conclusions:Results suggest that onset of sleep disturbances rather than short or long sleep mark an increase in physiological risk factors, which may partly explain the higher risk of CVD observed among impaired sleepers.Commentary:A commentary on this paper appears in this issue on page 1629.Citation:Clark AJ, Salo P, Lange T, Jennum P, Virtanen M, Pentti J, Kivimäki M, Rod NH, Vahtera J.

Actigraphy Measured Sleep Indices and Adiposity: The Multi-Ethnic Study of Atherosclerosis (MESA)
Conclusions:Among an older multi-ethnic cohort, we found robust associations across multiple indices of sleep and adiposity. Targeting sleep characteristics may be of benefit in obesity interventions, but more research is needed to rule out reverse causality.Citation:Ogilvie RP, Redline S, Bertoni AG, Chen X, Ouyang P, Szklo M, Lutsey PL.

The Sleep/Wake Cycle is Directly Modulated by Changes in Energy Balance
Conclusions:We demonstrate that changes in energy homeostasis directly and reversibly impact on the sleep/wake cycle. These findings provide a mechanistic framework for investigating the association between sleep duration and obesity risk.Citation:Collet TH, van der Klaauw AA, Henning E, Keogh JM, Suddaby D, Dachi SV, Dunbar S, Kelway S, Dickson SL, Farooqi IS, Schmid SM.

Sleep Restriction Impairs Vocabulary Learning when Adolescents Cram for Exams: The Need for Sleep Study
Conclusions:Spaced learning conferred strong protection against the effects of sleep restriction on recall performance, whereas students who had insufficient sleep were more likely to forget items studied over short time intervals. These findings in adolescents demonstrate the importance of combining good study habits and good sleep habits to optimize learning outcomes.Citation:Huang S, Deshpande A, Yeo SC, Lo JC, Chee MW, Gooley JJ. Sleep restriction impairs vocabulary learning when adolescents cram for exams: the Need for Sleep Study.SLEEP 2016;39(9):1681–1690. (Source: Sleep)

Exposure to Blue Light Increases Subsequent Functional Activation of the Prefrontal Cortex During Performance of a Working Memory Task
Conclusions:This is the first study to suggest that a relatively brief, single exposure to blue light has a subsequent beneficial effect on working memory performance, even after cessation of exposure, and leads to temporarily persisting functional brain changes within prefrontal brain regions associated with executive functions. These findings may have broader implication for using blue-enriched light in a variety of work settings where alertness and quick decision-making are important.Citation:Alkozei A, Smith R, Pisner DA, Vanuk JR, Berryhill SM, Fridman A, Shane BR, Knight SA, Killgore WD.

Restricting Time in Bed in Early Adolescence Reduces Both NREM and REM Sleep but Does Not Increase Slow Wave EEG
Conclusions:Our findings suggest that the selective NREM reduction and the small increase in REM we observed longitudinally across 9–18 years are not produced by sleep restriction. We hypothesize that the selective NREM decline reflects adolescent brain maturation (synaptic elimination) that reduces the need for the restorative processes of NREM sleep.Citation:Campbell IG, Kraus AM, Burright CS, Feinberg I. Restricting time in bed in early adolescence reduces both NREM and REM sleep but does not increase slow wave EEG.SLEEP 2016;39(9):1663–1670. (Source: Sleep)

Racial/Ethnic and Socio-Contextual Correlates of Chronic Sleep Curtailment in Childhood
Conclusions:Chronic sleep curtailment from infancy to mid-childhood was more prevalent among black, Hispanic, and Asian children. These differences were partially but not entirely explained by socio-contextual variables. Independently, children from lower socioeconomic status and those with greater exposures to TV also had greater sleep curtailment.Citation:Peña MM, Rifas-Shiman SL, Gillman MW, Redline S, Taveras EM.

Interaction between Obstructive Sleep Apnea and Shortened Telomere Length on Brain White Matter Abnormality

The results generate new hypotheses regarding mechanisms of impaired brain health in sleep apnea.Citation:Choi KM, Thomas RJ, Yoon DW, Lee SK, Baik I, Shin C.
