Obstructive sleep apnea (OSA) is a chronic and common adult disorder characterized by recurrent episodes of upper-airway obstruction and reopening during sleep. OSA is associated with intermittent hypoxia, sympathetic overactivity, oxidative stress and high cardiovascular mortality and morbidity. It is known to be more common in men than women, partly due to differences in anatomy and functional respiratory components. There are also gender differences in reported symptoms, leading to potential under-diagnosis in females. This gender difference tends to decrease after menopause, demonstrating a role of menopausal status itself in OSA phenotypes. Aging, fat mass distribution, sex hormones and upper-airway collapsibility are postulated to play a major role in these findings. This review focuses on the most recent studies exploring gender differences in the prevalence, pathogenesis and clinical features of OSA. It discusses the role of menopause in this, and explore the underlying pathophysiological mechanisms.

Background: Obstructive sleep apnea (OSA) is frequently associated with increased incidence and mortality of pulmonary hypertension (PH). The immune response contributes to pulmonary artery remodeling and OSA-related diseases. The immunologic factors linked to OSA-induced PH are not well understood.

Background: Accumulating research highlights that exposure to serum brominated flame retardants (BFRs) may elevate health risks. The effects of serum BFRs, both alone and in combination, on obstructive sleep apnea syndrome (OSAS) have not been thoroughly studied. Our main goal was to examine the association between individual and mixtures of serum BFRs and OSAS risk.

Objectives: The presented study aimed to evaluate the effect of mandibular protrusion with a temporarily applied mandibular advancement device (MAD) on the posterior airway space and to determine a reliable metric constant based on a three-dimensional computed tomography (CT) evaluation.
Materials And Methods: The study population consisted of patients with oral squamous cell carcinoma who were treated at least six months prior to the follow-up CT in supine position. Each patient received an individually adjusted MAD that was temporarily applied with three different protrusion distances (P = 0 mm, P = 4 mm, and P = 8 mm) during follow-up CT.

To assess the impact of resident involvement and resident postgraduate year (PGY) on head and neck obstructive sleep apnea (OSA) surgical outcomes. We analyzed head and neck OSA surgeries from 2005-2012 via the National Surgical Quality Improvement Program database. Demographic, preoperative, and postoperative variables were analyzed via multivariate regression to determine the impact of resident involvement and resident PGY on 30-day outcomes.

Obstructive Sleep Apnea (OSA) is a prevalent sleep disorder marked by repeated episodes of partial or complete upper airway obstruction during sleep, which leads to intermittent hypoxia and fragmented sleep. These disruptions negatively impact cardiovascular health, metabolic function, and overall quality of life. Obesity is a major modifiable risk factor for OSA, as it contributes to both anatomical and physiological mechanisms that increase the likelihood of airway collapse during sleep.
