PURPOSE: Obstructive sleep apnea (OSA) is the most commonly seen clinical sleep disorder. STOP-Bang, a widely used screening tool, yields a composite score based on eight dichotomized items including male gender. This study was designed to validate STOP-Bang among clinically referred patients and tested alternative scoring designs on tool performance, with a focus on gender differences in OSA. METHOD: STOP-Bang was administered to 403 female and 532 male subjects, followed by comprehensive sleep evaluation that included measurement of apnea-hypopnea indexes...

Edita Fino, Michela Mazzetti
Smartphone applications are considered as the prime candidate for the purposes of large-scale, low-cost and long-term sleep monitoring. How reliable and scientifically grounded is smartphone-based assessment of healthy and disturbed sleep remains a key issue in this direction. Here we offer a review of validation studies of sleep applications to the aim of providing some guidance in terms of their reliability to assess sleep in healthy and clinical populations, and stimulating further examination of their potential for clinical use and improved sleep hygiene...

PURPOSE: Obstructive sleep apnea (OSA) is associated with increased levels of systemic inflammatory markers, increased arterial stiffness, and endothelial dysfunction, which may lead to increased cardiovascular risk. We aimed to quantify the effects of continuous positive airway pressure (CPAP) on cardiovascular biomarkers and to establish predictors of response to CPAP. METHODS: We searched PubMed and the Cochrane Library from inception to May 31, 2017. Randomized controlled trials (RCTs) assessing the efficacy of CPAP on high-sensitivity C-reactive protein (hs-CRP), interleukin 6 (IL-6), tumor necrosis factor- alpha (TNF-α), augmentation index (AIx), pulse wave velocity (PWV), and flow-mediated dilatation (FMD) in patients with OSA were selected by consensus...

PURPOSE: Cumulative evidence supports the clear relationship of obstructive sleep apnea (OSA) with cardiovascular disease (CVD). And, adherence to continuous positive airway pressure (CPAP) treatment alleviates the risk of CVD in subjects with OSA. Vascular endothelial growth factor (VEGF), a potent angiogenic cytokine regulated by hypoxia-inducible factor, stimulates the progression of CVD. Thus, whether treatment with CPAP can actually decrease VEGF in patients with OSA remains inconclusive...

INTRODUCTION: Obstructive sleep apnea (OSA) is common, and diagnosis requires expensive and laborious testing to assess the apnea hypopnea index (AHI). We performed an analysis to explore the relationship between the oxygen desaturation index (ODI) as measured with pulse oximetry and the AHI in our large portable monitoring (PM) database to find an optimal cutoff value for the ODI in order to be able to exclude AHI ≥ 5 on PM. METHODS: Three thousand four hundred thirteen PM recordings were randomly divided into a training set (N = 2281) and a test set (N = 1132)...

REVIEW
Saad Mohammed AlShareef, Richard Mark Smith, Ahmed Salem BaHammam
Kleine-Levin syndrome (KLS) is the commonest recurrent sleep disorder, with a prevalence of 1-2 per million population. Clear diagnostic criteria are now defined, but effective treatment remains elusive. The significant body of published literature allows consideration of possible aetiological mechanisms, an understanding of which could guide the development of therapeutic strategies. Functional imaging studies have been inconclusive; although diencephalic abnormalities are a common finding, no consistent pattern has emerged, and these studies have not revealed the mechanism(s) underlying the development of the abnormalities detected...

Currently, the relationship between uvula size and sleep-disordered breathing (snoring and obstructive sleep apnea) lacks data for objective interpretation. This study conducted a systematic review of the international literature for research describing the measurable characteristics of the uvula (i.e., size, length, width) and any association with snoring and obstructive sleep apnea (OSA). PubMED, Scopus, Google Scholar, Embase, and the Cochrane Library were each systematically searched from inception through November 15, 2016...

PURPOSE: In 2005, the American Academy of Sleep Medicine stated, "Oral appliances are indicated for use in patients with mild to moderate obstructive sleep apnea (OSA) who prefer them to CPAP therapy, or who do not respond to, are not appropriate candidates for, or who fail treatment attempts with CPAP." However, this recommendation is based upon variable results from only six studies with more than 100 participants. These studies have assessed the effectiveness of mandibular advancement devices (MADs) in specific groups (military populations, academic institutions, or hospital settings) with no large study conducted in a fee-for-service private practice where the majority of patients receive MADs for OSA...

PURPOSE: Until now, there is no clear consensus on optimal care for mild sleep-related breathing disorders (SRBD) in general or for positional obstructive sleep apnea (POSA) in particular. Most proposed treatment options are either invasive and/or expensive. Positional therapy (PT) may therefore present as a valuable first-line intervention in POSA. METHODS: Twenty-eight patients presenting with POSA were enrolled in a prospective cohort study. The protocol consisted of three nights of polysomnography (PSG) in an academic sleep lab...
