The incidence of obstructive sleep apnea has been underestimated in morbidly obese patients who present for evaluation for weight loss surgery. This retrospective study shows that the incidence of obstructive sleep apnea in this patient population is greater than 70 per cent and increases in incidence as the body mass index increases. Obstructive sleep apnea (OSA) is a common comorbidity in obe...

CONTEXT AND OBJECTIVE Impaired autonomic cardiac function is an important consequence of obstructive sleep apnea (OSA). This impairment is mainly due to intermittent hypoxia episodes following apneas. However, the impact of apnea severity on autonomic cardiac function remains unclear. The aim of this study was to evaluate the relationship between the severity of sleep apnea and heart rate turbu...

leep apnea has an association with various cardiovascular diseases and generally, it is classified as either obstructive sleep apnea (OSA) or central sleep apnea (CSA). OSA is a well-known trigger of cardiovascular diseases, whereas CSA is associated with cardiac pathologies that could further worsen prognosis. CSA, rather than OSA, is common in patients with heart failure. However, OSA and CSA...

background and objective: obstructive sleep apnea (osa) is a disease with serious consequences. many portable devices have been developed to overwhelm some of limitations in the accessibility of the gold standard test for osa, polysomnography (psg). this study aimed to determine diagnostic accuracy of a portable sleep apnea screener against psg in patients of a sleep clinic. materials and metho...

Introduction: Obstructive sleep apnea (OSA) is a highly prevalent sleep-disordered breathing (SDB).   Case Report: Two 53- and 51-year-old male cases with daytime sleepiness and opium abuse and severe sleep apnea and long respiratory events duration (200 and 275 seconds respectively) noted in polysomnography were reported at Ebn-e-Sina and Razavi hospita...

Obstructive sleep apnea (OSA) has been the engine that has driven the remarkable growth of the sleep field over the last 25 years. Although the medical community and the general public have been interested in the performance and quality-of-life problems that result from sleep apnea, the real concern has been the potential relationship between OSA and the cardiovascular system. This goes back as...

ABSTRACT The Board of Directors of the American Academy of Sleep Medicine (AASM) commissioned a Task Force to develop quality measures as part of its strategic plan to promote high quality patient-centered care. Among many potential dimensions of quality, the AASM requested Workgroups to develop outcome and process measures to aid in evaluating the quality of care of five common sleep disorders...

Obstructive sleep apnea (OSA) occurs frequently in people with Down syndrome (DS) with reported prevalences ranging between 55% and 97%, compared to 1-4% in the neurotypical pediatric population. Sleep studies are often uncomfortable, costly, and poorly tolerated by individuals with DS. The objective of this study was to construct a tool to identify individuals with DS unlikely to have moderate...

A patient with obesity resulting from sleep-related eating disorder demonstrated signs and symptoms of obstructive sleep apnea (OSA). Incarceration restricted access to food during the night, leading to weight loss and clinical improvement. Release from prison allowed recurrence of unrestricted sleep-eating, recurrent obesity, and documented OSA. Successful treatment of sleep-related eating dis...

The aim of the present cohort study was to evaluate possible occurrence central sleep apnea (CSA) in patients with obstructive (OSA) after treatment a mandibular advancement device (MAD). In this case, 56 OSA treated MAD were enrolled. Inclusion criteria age over 20 years, body mass index (BMI) less than 34 kg/m2, diagnosis confirmed by polysomnography (PSG), and therapy for OSA. Exclusion smok...
