Study of the obstructive sleep apnea syndrome in cerebral infarction patients
ConclusionObstructive sleep apnea Syndrome is a factor in the prognosis of cerebral infarction as well as cardiovascular diseases such as hypertension. Thus, understanding the risk of stroke in people with sleep apnea is necessary and working with a doctor to diagnose and treat sleep apnea is important.

The relationship between cephalometric carotid artery calcification and Framingham Risk Score profile in patients with obstructive sleep apnea.
CONCLUSION: While the presence of a calcified mass on a cephalometric radiograph is not diagnostic of atherosclerosis, this information indicates some cardiovascular risk. PMID: 23208741 [PubMed - as supplied by publisher]

Untreated obstructive sleep apnea and the risk for serious long-term adverse outcomes: A systematic review
Conclusion: Evidence exists in men for a relationship between OSA and all-cause mortality and a composite CV outcome. Associations between OSA and other outcomes remain uncertain. Among OSA-specific markers, only AHI was a consistent predictor. Other consistent predictors were traditional CV risk factors. Research is required to identify effect modifiers and the predictive ability of various AHI threshold values and hypopnea definitions. An enhanced set of OSA-specific predictors will allow better risk stratification to guide OSA treatment.

Comparing Periodic Limb Movements in Sleep in Subjects with and without Waking Paretic/Plegic Limbs (P5.286)
CONCLUSIONS: In this study, PLMS were more prevalent in subjects with waking paralysis/paresis compared to those without waking paralysis/paresis. We intend to meticulously analyze these PLMS and identify, qualify and quantify unique elements that more accurately approximate surviving neuronal connections between cortex/brainstem sleep and spinal movement centers, to improve prognostication and selection of paralyzed patients regarding aggressive physical/functional electrical stimulation therapies.Disclosure: Dr. Dyken has received research support for a study concerning Obstructive Sleep Apnea. Dr. Zimmerman has nothing ...

Who Is Getting Tested for Obstructive Sleep Apnea Using a Portable Recording System? Test Results from 193,221 Patients
Conclusions:The majority of PR has been conducted on patients with a high degree of suspicion for OSA. These data suggest that PR has been used in patients with a high pretest probability of OSA. Patients with a history of insomnia, stroke, and/or lung disease may especially benefit by a comprehensive evaluation by a physician trained in sleep medicine, especially if PR results are negative for OSA. Future studies should evaluate the utility of gender-appropriate screening measures. Although questionnaire-based screening is helpful in determining OSA risk, it is imperative that it be used in conjunction with clinical decis...

Cerebral blood flow (CBF) response to orthostatic stress in patients with obstructive sleep apnea (OSA)
Conclusions:These preliminary results suggest an impairment cerebral vascular reactivity in severe OSA patients related with obesity and oxygen saturation. Diffuse optical techniques may allow noninvasive assessment of the involvement of the cerebral microvasculature.1) B. L. Edlow et al, Physiological Meas 2010.2) T.

Long-Term Cost-Effectiveness of Upper Airway Stimulation for the Treatment of Obstructive Sleep Apnea: A Model-Based Projection Based on the STAR Trial
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.

Hypertension and sleep apnea
Publication date: Available online 16 May 2015 Source:Canadian Journal of Cardiology Author(s): John S. Floras Obstructive sleep apnea is more prevalent in patients with hypertension than in the general population and many with obstructive sleep apnea also have hypertension. Obstructive sleep apnea increases the risk of hypertension-related morbidities such as stroke, heart failure, and premature death. Are such associations co-incidental or causal and if the latter, what are its implications for clinical practice? Despite compelling epidemiological and mechanistic links between obstructive sleep apnea and hypertension, ...

Obstructive sleep apnea is a common disorder in the population-a review on the epidemiology of sleep apnea.
Authors: Franklin KA, Lindberg E Abstract The prevalence of obstructive sleep apnea (OSA) defined at an apnea-hypopnea index (AHI) ≥5 was a mean of 22% (range, 9-37%) in men and 17% (range, 4-50%) in women in eleven published epidemiological studies published between 1993 and 2013. OSA with excessive daytime sleepiness occurred in 6% (range, 3-18%) of men and in 4% (range, 1-17%) of women. The prevalence increased with time and OSA was reported in 37% of men and in 50% of women in studies from 2008 and 2013 respectively. OSA is more prevalent in men than in women and increases with age and obesity. Smoking and al...

OSA results in nocturnal cerebral hypoxia which is prevented by CPAP - Data from a randomised controlled trial
Conclusions: CPAP therapy withdrawal – and thus recurrence of OSA – results in intermittent and sustained nocturnal cerebral tissue deoxygenation to a degree reported to cause functional impairment. These findings suggest that patients with untreated OSA are at increased risk of nocturnal cerebral damage, a threat than can be prevented by CPAP therapy.
