TL;DR: The choice of therapy should be tailored to the individual patient with sleep apnea, and careful follow-up is essential to ensure a positive response to therapy.
Abstract: Obstructive sleep apnea syndrome is the most common cause of hypersomnolence in patients referred to sleep disorders centers. This type of sleep apnea is characterized by loud snoring, nocturnal oxyhemoglobin desaturation, and disrupted sleep that leads to daytime hypersomnolence. The anatomic configuration of the pharynx and the physiologic responses to occlusion of the upper airway play a major role in the pathogenesis of this disorder. Polysomnography can accurately identify obstructive sleep apnea, and the multiple sleep latency test allows an objective measurement of daytime alertness. Weight loss and training the patient to sleep in a lateral position are frequently used to alleviate mild cases. Nasally applied continuous positive airway pressure is an extremely effective modality for treating moderate and severe obstructive sleep apnea. Surgical correction of obvious anatomic defects has a role in diminishing obstructive sleep apnea, but the exact role of surgical intervention in patients without obvious anatomic defects remains unknown. The choice of therapy should be tailored to the individual patient with sleep apnea, and careful follow-up is essential to ensure a positive response to therapy.

TL;DR: It is concluded that SEE decreases and weight improves after resolution of OSAS and it is speculated that the poor growth seen in some children with OSAS is secondary to increased caloric expenditure caused by increased work of breathing during sleep.

TL;DR: Common diseases and disease mechanisms in OSA and obesity suggest that conditions related to obesity may be better managed if patients, particularly those who are morbidly obese, are evaluated and treated for previously undiagnosed OSA.

TL;DR: Although perimenopausal and postmenopausal women were less satisfied with their sleep, menopause was not a strong predictor of specific sleep-disorder symptoms, and symptoms and signs of sleep abnormalities in midlife women should not be attributed primarily toMenopause before ruling out underlying sleep disorders.
Abstract: Study Objective: Assess objectively measured sleep quality in premenopausal, perimenopausal, and postmenopausal women. Design: Observational epidemiology study. Setting: Community-based. Participants: Probability sample of 589 premenopausal, perimenopausal, and postmenopausal women recruited from state employee records. Interventions: None. Measurements and Results: Menopausal status was determined by menstrual history, surgical history, and use of hormone replacement therapy. Sleep quality was objectively measured by full in-laboratory polysomnography and by self-reported sleep problems. Linear and logistic regression were used to estimate associations adjusted for potential confounding factors. Objective: Sleep quality was not worse in perimenopausal or postmenopausal women, compared with premenopausal women. To the contrary, postmenopausal woman had more deep sleep (16% vs 13% stages 3/4, P<0.001) and significantly longer total sleep time (388 minutes vs 374 minutes, P=0.05). Menopausal status was moderately related to self-reported dissatisfaction with sleep but was not consistently associated with symptoms of insomnia or sleepiness. Conclusions: Menopause is not associated with diminished sleep quality measured by polysomnography. Although perimenopausal and postmenopausal women, relative to premenopausal women, were less satisfied with their sleep, menopause was not a strong predictor of specific sleep-disorder symptoms. Symptoms and signs of sleep abnormalities in midlife women should not be attributed primarily to menopause before ruling out underlying sleep disorders. Citation: Young T; Rabago D; Zgierska A et al.

TL;DR: In the wake of traumatic events, subjective reports of sleep disturbance are common and objectively confirmed sleep disorders after traumatic events are examined.
Abstract: In the wake of traumatic events, subjective reports of sleep disturbance are common. This review article examines both subjectively identified and objectively confirmed sleep disorders after traumatic events. Recommendations with respect to diagnostic procedures and therapeutic options are also reviewed.
