Objectives: This study evaluated whether the symptoms of laryngopharyngeal reflux (LPR) change after multilevel surgery for obstructive sleep apnea (OSA). Methods: Patients who underwent multilevel surgery for OSA between April 2009 and September 2014 were enrolled in this study. All patients underwent preoperative polysomnography prior to surgery and were asked to complete the reflux symptom index (RSI) questionnaire before and after surgery. Results: Of 73 enrolled patients, 24 (33%) reported an RSI score >13 and were thus classified as having reflux...

Sleep disorders are a critical issue for the military, as they impact operational readiness, personnel health, wellbeing and health-care costs. The incidence of insomnia and obstructive sleep apnea (OSA) are increasing in the United States civilian population, and rates in military personnel exceed those of civilians. Using a comprehensive database, rates of medical encounters for insomnia and OSA were investigated and their associations with various demographic factors examined in the total US military population [1,381,406 ± 25,123, mean ± standard deviation (SD) personnel per year] from 2005 to 2014...

OBJECTIVES: Obstructive sleep apnea syndrome (OSAS) is associated with major morbidity and mortality but OSAS is frequently under recognized. To promote awareness of OSAS, the Swiss Lung League launched an online questionnaire combined with annual advertisements in mass media. Characteristics of participants, prevalence of sleep apnea, OSAS-related symptoms, and their association with accidents were investigated. METHODS: A questionnaire was created incorporating anthropometrics, the Epworth sleepiness scale (ESS), the OSAS domain of the sleep disorders questionnaire (SDQ), and a question on accidents related to sleepiness...

Study Objectives: Weight loss fails to resolve obstructive sleep apnea (OSA) in most patients, however it is unknown as to whether weight loss differentially affects OSA in the supine compared to non-supine sleeping positions. We aimed to determine if weight loss in obese OSA patients results in a greater reduction in the non-supine Apnea Hypopnea Index (AHI) compared to the supine AHI, thus converting subjects into supine predominant OSA. Methods: Post hoc analysis of data from a randomized controlled trial assessing the effect of weight loss (bariatric surgery vs medical weight loss) on OSA in 60 obese subjects (body mass index: >35 and <55) with recently diagnosed (<6 months) OSA and AHI of ≥ 20 events/hour...

REVIEW
Walter T McNicholas
Chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea syndrome (OSA) are both highly prevalent, which implies that both disorders occurring together (overlap syndrome) is likely to be common based on chance association alone. However, different clinical COPD phenotypes influence the likelihood of co-existing OSA in that the increased lung volumes and low body mass index (BMI) associated with the predominant emphysema phenotype protects against OSA, whereas the higher likelihood of peripheral edema and increased BMI associated with the predominant chronic bronchitis phenotype promotes OSA...

OBJECTIVE: Patients with obesity are at risk for chronic kidney disease. The aim is to characterize the spectrum of kidney disease in these patients, which may be related to obesity, termed obesity-related glomerulopathy (ORG), or may have other diseases secondary to associated or unassociated medical conditions. METHODS: Native kidney biopsies from 2000 to 2012 were retrospectively reviewed from all patients with body mass index >30kg/m(2). Glomerular diameter was measured using a standard micrometer and clinicopathologic characteristics were analyzed...

Socioeconomic status (SES) is defined as an individual's social or economic standing, and is a measure of an individual's or family's social or economic position or rank in a social group. It is a composite of several measures including income, education, occupation, location of residence or housing. Studies have found a lower SES has been linked to disproportionate access to health care in many diseases. There is emerging data in pulmonary diseases such as COPD, asthma, cystic fibrosis, pulmonary hypertension and other chronic respiratory conditions that allude to a similar observation noted in other chronic diseases...

Chronic intermittent hypoxia (CIH), the hallmark of obstructive sleep apnea syndrome (OSAS), has been reported to play a key role in the development of OSAS-associated cardiovascular diseases including cardiac remodeling. RhoA/Rho-kinase (ROCK) pathway has also been implicated in myocardial remodeling, but the exact mechanisms are not fully elucidated. The current study's purpose is to investigate the influence of fasudil, a selective ROCK inhibitor, on CIH-induced left ventricular remodeling in rats and its possible mechanisms...

Continuous positive airway pressure (CPAP) is currently the most used and efficient therapy in OSAS. Efficiency of CPAP on sleep respiratory disorders is the same whether in fixed or automatic mode. Larger studies are required to evaluate their respective beneficial impact on cardiovascular or metabolic complications of OSAS. Close medical monitoring is necessary during the first weeks of CPAP therapy. Compliance to CPAP therapy is crucial for efficacy in preventing cardiovascular or metabolic complications of OSAS...

While chronic systemic inflammation in obstructive sleep apnea (OSA) has been traditionally considered a consequence of intermittent hypoxia, several treatment studies targeting inflammation suggest that this process may precede the development of the disorder. A recent cross-sectional study in the Penn State Child Cohort (PSCC) revealed that inflammation largely mediates the association between visceral adiposity and OSA in adolescence. The purpose of this study was to examine for the first time whether, longitudinally, inflammation precedes OSA during this developmental period...

OBJECTIVE: Patients with heart failure (HF) and sleep disordered breathing (SDB) are typically not sleepy, unlike patients without heart failure. Previous work in HF patients with obstructive SDB suggested that sleepiness was associated with a reduction in daytime activity. The consequences of predominately central SDB on sleepiness in HF are less well understood. The aim of this study was to test the hypothesis that subjective sleepiness is associated with reduced daytime activity in HF patients with central SDB, compared to those without SDB...
