Evaluation of human obstructive sleep apnea using computational fluid dynamics. [PDF]

, 2019
Obstructive sleep apnea (OSA) severity might be correlated to the flow characteristics of the upper airways. We aimed to investigate the severity of OSA based on 3D models constructed from CT scans coupled with computational fluid dynamics (CFD ...

Fast cycle of vagus nerve stimulation is associated with increased sleep‐related breathing disorder in patients with epilepsy

Epilepsia, EarlyView.
Abstract Objective This work was undertaken to study the association between vagus nerve stimulation (VNS) parameters and the apnea–hypopnea index (AHI) measured by polysomnography in patients with drug‐resistant epilepsy. Methods Patients with epilepsy who underwent polysomnography with an active VNS device between 2018 and 2023 were retrospectively ...

Effectiveness of Maxillomandibular advancement (MMA) surgery in sleep apnea treatment: Case report

Sleep Science, 2016
Obstructive sleep apnea (OSA) is characterized by episodes of pharyngeal collapse during sleep. Craniofacial alterations such as retrognathia are often found in OSA patients. Maxillomandibular advancement (MMA) surgeries increase the pharyngeal space and

The Benefit of Sleeve Gastrectomy in Obese Adolescents on Nonalcoholic Steatohepatitis and Hepatic Fibrosis [PDF]

, 2017
Objective To determine whether bariatric surgery is effective for the treatment of nonalcoholic steatohepatitis (NASH) in adolescence, we compared the efficacy of laparoscopic sleeve gastrectomy (LSG) with that of lifestyle intervention (nonsurgical ...

Obstructive Sleep Apnea Following Head and Neck Chemoradiation: A Scoping Review With Exploratory Meta‐Analysis

Head &Neck, EarlyView.
ABSTRACT Background Obstructive sleep apnea (OSA) may contribute to fatigue in head and neck cancer patients undergoing chemotherapy and radiotherapy, particularly as both have the potential to impact the mechanics and dynamics of the airway.

Brain Age from the Electroencephalogram of Sleep [PDF]

, 2018
The human electroencephalogram (EEG) of sleep undergoes profound changes with age. These changes can be conceptualized as "brain age", which can be compared to an age norm to reflect the deviation from normal aging process.

Cardiac autonomic control in the obstructive sleep apnea [PDF]

Libyan Journal of Medicine, 2015
Introduction: The sympathetic activation is considered to be the main mechanism involved in the development of cardiovascular diseases in obstructive sleep apnea (OSA). The heart rate variability (HRV) analysis represents a non-invasive tool allowing the

Effects of the CPAP Treatment on the NON-REM Sleep Microstructures in Patients with Severe Apnea-Hypoapnea Syndrome [PDF]

, 2014
Sleep quality is affected in patients with sleep apnea- hypopnea syndrome (SAHS) with nocturnal and diurnal consequences. Most of these patients who are treated with positive airway pressure (CPAP) return to normal sleep patterns.
