High prevalence of post-stroke sleep disordered breathing in mexican americans
• Mexican American (MA) stroke patients have a high burden of SDB.• SDB risk factors and stroke severity do not explain greater prevalence of SDB in MAs.• Physicians treating MA stroke patients should have a high index of suspicion for SDB.

High prevalence of poststroke sleep-disordered breathing in Mexican Americans
Sleep-disordered breathing (SDB) is common in middle-aged and older adults in the United States, with recent work suggesting a higher prevalence in Hispanics compared with non-Hispanic whites (NHWs) [1]. SDB is also highly prevalent post stroke, with prevalence estimates>50% [2]. As the existing studies of poststroke SDB have largely been conducted in NHW populations, whether the ethnic difference in SDB observed in the general population extends to the stroke population remains unclear. Mexican Americans (MAs), the largest subpopulation of Hispanic Americans, have an increased risk of stroke and worse outcomes following i...

Identifying obstructive sleep apnea after stroke/TIA: evaluating four simple screening tools
We examined whether paper-based screening tools could rule out OSA after stroke/TIA• We evaluated 69 patients (53 with stroke, 16 with TIA); 32 patients (46.4%) had OSA• The 4V and STOP-BAG were the best tools for ruling out OSA• Future work should refine these tools to enhance their utility after stroke/TIA

Regional Neocortical Gray Matter Structure and Sleep Fragmentation in Older Adults
Conclusions:Lower cortical gray matter volume in the lateral orbitofrontal cortex and inferior frontal gyrus pars orbitalis is associated with greater sleep fragmentation in older community-dwelling adults. Further work is needed to clarify whether this is a consequence of or contributor to sleep fragmentation.Commentary:A commentary on this article appears in this issue on page 15.Citation:Lim AS, Fleischman DA, Dawe RJ, Yu L, Arfanakis K, Buchman AS, Bennett DA. Regional neocortical gray matter structure and sleep fragmentation in older adults. SLEEP 2016;39(1):227–235.

Lack of Association between Genetic Risk Loci for Restless Legs Syndrome and Multimorbidity
Conclusions:Based on these results it is unlikely that known genetic risk factors for RLS would lead to increased multimorbidity.Citation:Szentkirályi A, Völzke H, Hoffmann W, Winkelmann J, Berger K. Lack of association between genetic risk loci for restless legs syndrome and multimorbidity. SLEEP 2016;39(1):111–115.

Sleep and Stroke
Evidence increasingly suggests sleep disorders are associated with higher risk of cardiovascular events, including stroke. Strong data correlate untreated sleep apnea with poorer stroke outcomes and more recent evidence implicates sleep disruption as a possible etiology for increased cerebrovascular events. Also, sleep duration may affect incidence of cardiovascular events. In addition, sleep-disordered breathing, insomnia, restless legs syndrome, and parasomnias can occur as a result of cerebrovascular events. Treatment of sleep disorders improve sleep-related symptoms and may also improve stroke recovery and risk of future events.

Nocturnal Hypoxemia Is Associated with White Matter Hyperintensities in Patients with a Minor Stroke or Transient Ischemic Attack
Conclusions:We conclude that nocturnal hypoxemia, predominantly related to OSA, is independently associated with WMH in patients who present with minor ischemic stroke and TIA and may contribute to its pathogenesis.Citation:Patel SK, Hanly PJ, Smith EE, Chan W, Coutts SB. Nocturnal hypoxemia is associated with white matter hyperintensities in patients with a minor stroke or transient ischemic attack. J Clin Sleep Med 2015;11(12):1417–1424.

The Determining Risk of Vascular Events by Apnea Monitoring (DREAM) study: design, rationale, and methods.
CONCLUSIONS: This manuscript provides the rationale for the inclusion of veterans in a study to determine the association between physiologic sleep measures and cardiovascular outcomes and specifically the development of a corresponding outcome-based prognostic model.

Sleep-disordered breathing among acute ischemic stroke patients in Brazil
• Obstructive sleep apnea (OSA) is very frequent in Brazilian patients with acute stroke.• Severe OSA was associated with a poor long-term functional outcome following stroke.• OSA is a treatable condition and therefore its treatment seems to be a potential target to improve outcome of acute stroke patients.

Comparison of in-laboratory and home diagnosis of sleep apnea using a cordless portable acoustic device
Sleep apnea (SA) is characterized by recurrent cessation of breathing during sleep. The two main types of SA are obstructive sleep apnea (OSA) and central sleep apnea (CSA). OSA is the most common type and is associated with hypersomnolence that increases the risk of motor vehicle accidents [1]. OSA also increases the risk of developing cardiovascular diseases including hypertension, heart failure, and stroke [2,3], and of death from cardiovascular diseases [4]. Patients with untreated OSA consume twice as many health-care resources for treatment of cardiorespiratory diseases as subjects without OSA [5].

Associations between Cardioembolic Stroke and Obstructive Sleep Apnea
Conclusions:There appears to be a strong association between obstructive sleep apnea (OSA) and cardioembolic (CE) stroke. In patients with OSA presenting with cryptogenic stroke, high clinical suspicion for CE is warranted. This may lead to consideration of diagnostic studies to identify CE risk factors such as paroxysmal atrial fibrillation (AF). CE strokes are more common in patients with OSA even after adjusting for AF. This finding may reflect a high rate of occult paroxysmal AF in this population; alternatively, OSA may lead to CE strokes through mechanisms independent of AF.Citation:Lipford MC, Flemming KD, Calvin AD...

Identification of Sleep-Modulated Pathways Involved in Neuroprotection from Stroke
Conclusion: Our data indicate that sleep deprivation before stroke reprogrammed the signaling response to injury. The inhibition of cell cycle regulation and inflammation are neuroprotective mechanisms reported also for other forms of preconditioning treatment, whereas the implication of the neuroendocrine function is novel and has never been described before. These results therefore provide new insights into neuroprotective mechanisms involved in ischemic tolerance mechanisms. Citation: Pace M, Baracchi F, Gao B, Bassetti C.
