Sleep dramatically influences cardiovascular regulation. Changes in sleep duration or quality as seen in sleep disorders may prevent blood pressure to fall during sleep as expected in human physiology. This supports the increased prevalence of hypertension and drug-resistant hypertension in those with sleep loss. Other cardiovascular outcomes i.e. coronary lesions seem to be associated with sle...

Background: Obstructive Sleep Apnea (OSA) has been observed to be common among people living with HIV/AIDS (PLWHA). Sleep scales can be used to screen patients at increased “risk” of OSA who can benefit from polysomnography. This study therefore sought to generate preliminary data on this often unattended complication of HIV Infection in Cameroon. Methods: A case control study carried out at th...

As a follow-up to a previous assessment of complications of sleep-disturbed breathing in 265 patients, we have reevaluated measures of sleepiness and hypertension in patients with obstructive sleep apnea (OSA) (n = 518), central sleep apnea (n = 50), and subclinical sleep-disordered breathing (SDB) (n = 107). Both subjective and objective (multiple sleep latency test [MSLT]) measures indicated ...

INTRODUCTION The Berlin questionnaire (BQ) is a common tool to screen for Obstructive Sleep Apnea (OSA) in the general population, but its application in the clinical sleep setting is still challenging. The aim of this study was to determine the specificity and sensitivity of the BQ compared to the apnea-hypopnea index obtained from polysomnography recordings obtained from a sleep clinic in Ira...

Obstructive sleep apnea (OSA) afflicts tens of millions of Americans and hundreds of millions of people worldwide, and the possibility that the disease may cause permanent neural injury is therefore a significant concern. Numerous comorbidities--including diabetes, cardiovascular disease, and obesity--are associated with the disease, and it is quite difficult, if not impossible, in clinical stu...

STUDY OBJECTIVES The authors reviewed neuroimaging studies of obstructive sleep apnea (OSA) to summarize findings, evaluate their contribution to a current understanding of the neurophysiology of the disorder, and propose directions for future research. METHOD Manuscripts were identified using the National Institutes of Health PubMed literature search system. Search terms included obstructive...

We describe a patient with obstructive sleep apnea (OSA) whose apnea-hypopnea index (AHI) improved remarkably in the prone position accompanied by an improved sleep quality, despite a higher AHI in the supine position and even in the lateral position. Magnetic resonance imaging revealed the most dilated upper airway in the prone position, which suggests the role of anatomical narrowing of the u...

Abstract Introduction Moderate-Severe Obstructive Sleep Apnea (OSA, AHI>15) disturbs sleep through frequent bouts of apnea and is associated with daytime sleepiness. However, many individuals without moderate or severe OSA (i.e. AHI≤15) also report We propose that sleepiness may be a consequence substantial flow limitation, even in the absence overt reductions airflow (apnea/hypopnea). M...

Abstract Background Obstructive Sleep Apnea (OSA) is one of the diseases related to diabetes. Considering varying prevalence OSA in patients with type 2 diabetes different parts world, order aggregate results and come a general review about topic mentioned, current study performed systematic meta-analysis Methods In this study, international databases (PubMed, Scopus, Web science, Cochran libra...

Obstructive sleep apnea (OSA) results from a structural compromise of the upper airway combined with decrease in muscle tone during sleep. Overt upper airway pathology is rare, however a variety of pharyngeal tumors have been well described as a cause of OSA. We describe a case of a mass originating in the carotid body resulting in severe OSA with hypersomnia resistant to positive pressure vent...
