Conclusions:Relative to the acknowledged willingness-to-pay threshold of $50,000–$100,000/QALY, our results indicate upper airway stimulation is a cost-effective therapy in the U.S. healthcare system.Citation:Pietzsch JB, Liu S, Garner AM, Kezirian EJ, Strollo PJ. Long-term cost-effectiveness of upper airway stimulation for the treatment of obstructive sleep apnea: a model-based projection based on the STAR Trial. SLEEP 2015;38(5):735–744.

Sleep apnea diagnosis varies with the hypopnea criteria applied.
CONCLUSION: The difference is significant between the AHIs achieved by the A- and the B-/2012-hypopnea criteria, with much lower AHIs achieved with the A-criteria. As SRBD treatment lessens the risk of complications, correct identification of SRBD patients is of the utmost importance. PMID: 26070533 [PubMed - as supplied by publisher]

Restless legs syndrome, a predictor of subcortical stroke: a prospective study in 346 stroke patients
Restless legs syndrome (RLS), first described by Ekbom in 17th century, is a common sleep-related movement disorder [1]. RLS is characterized by four essential criteria established by the International Restless Legs Syndrome Study Group (IRLSSG) [2]: namely, an urge to move the legs, usually accompanied or caused by uncomfortable and unpleasant sensations in the legs; beginning or worsening during periods of rest or inactivity, such as lying down or sitting; partial or total relief by movement, such as walking or stretching, at least as long as the activities are continued; and worsening in the evening or at night as compa...

Decreased cerebral vasomotor reactivity in patients with obstructive sleep apnea syndrome
In obstructive sleep apnea syndrome (OSAS), any of the activated neural, vascular, hemodynamic, metabolic, inflammatory, and thrombotic mechanisms may be related to increased cerebrovascular disease and risk of death; however, the possible pathophysiological process between obstructive sleep apnea syndrome and stroke has not been clearly explained. We hypothesize that alterations in vasomotor reactivity in patients may be responsible for their altered cerebral blood flow, and may contribute to the increased risk of ischemic stroke.

Obstructive sleep apnea increases the risk of cardiac events after percutaneous coronary intervention: a meta-analysis of prospective cohort studies.
CONCLUSIONS: In patients after PCI, OSA appears to increase the risk of cardiac death, non-fatal MI, and coronary revascularization. PMID: 28421375 [PubMed - as supplied by publisher]

Risk of gallstones in patients with obstructive sleep apnea: a nationwide observational cohort study.
CONCLUSION: The study shows a strong association between OSA and gallstones. Moreover, our findings suggest the requirement for survey and health education for gallstones in OSA and further studies to verify whether the treatment of OSA can reduce the risk of gallstones.

Good long-term adherence to continuous positive airway pressure therapy in patients with resistant hypertension and sleep apnea.
rcia MA, on behalf the Spanish Sleep Network Abstract Although adequate adherence is paramount in achieving the beneficial effects of continuous positive airway pressure therapy in patients with obstructive sleep apnea, long-term adherence and the variables involved in continuous positive airway pressure compliance in patients with resistant hypertension and obstructive sleep apnea are yet unknown. We conducted a prospective, multicentre, observational study in 177 patients recruited from hypertensive units with resistant hypertension confirmed by means of 24-hr blood pressure monitoring (blood pressure ≥ 130 ...

Self-reported snoring and incident cardiovascular disease events: results from the Jackson Heart Study.
CONCLUSION: In conclusion, self-reported habitual snoring was not associated with incident CVD among this large African American cohort. Future studies providing objective data on snoring and sleep apnea may provide more information on the snoring-CVD association among African Americans.

30 Days to Better Sleep: Snoring and Sleepiness Equals Sleep Apnea
In reviewing the articles in this blog series, you may have become convinced that the only thing that affects sleep is not sleeping as part of insomnia. However, there are many other sleep disorders that can contribute to difficulty sleeping and waking refreshed. One of the major contributors to excessive sleepiness during the day is trouble breathing at night, best characterized by sleep apnea. Sleep apnea occurs when the upper airway collapses during sleep. Tissues in the airway, from the nose past the soft palate to the base of the tongue, may obstruct the flow of air. When this occurs, this obstruction may be partial ...

A time sequence analysis of the relationship between cardiovascular risk factors, vascular diseases and restless legs syndrome in the general population.
Abstract Previous cross-sectional studies regarding the association of restless legs syndrome (RLS) with cardiovascular morbidity are controversial. Our aim was to evaluate prospectively the relationship of cardiovascular risk factors and vascular diseases with incident RLS in the general population. The results are from two prospective population-based cohort studies: the Dortmund Health Study (n = 1312, median follow-up of 2.1 years) and the Study of Health in Pomerania (n = 4308, median follow-up of 5.0 years). RLS status was assessed twice according to the minimal criteria. Diabetes, hypertension, myocar...

Obstructive sleep apnoea as a risk factor for silent cerebral infarction.
This study recruited a total of 746 participants (252 men and 494 women) aged 50-79 years as part of the Korean Genome and Epidemiology Study (KoGES); they underwent polysomnography, brain magnetic resonance imaging and health screening examinations. SCI was assessed by subtypes and brain regions, and lacunar infarction represented lesions <15 mm in size in the penetrating arteries. Moderate-severe OSA was determined by apnoea-hypopnoea index ≥15. The results indicated that 12.06% had moderate-severe OSA, 7.64% of participants had SCI and 4.96% had lacunar infarction. Moderate-severe OSA was associated positively wi...
