“…In addition, the OVS group had more o ce clerks or workers, which may correspond to more current smoking and alcohol consumption, higher BMI and larger neck circumference, which are established risk factors for OSA. 6,15,[20][21][22][23][24] Cigarette smoking was very popular in these COPD patients. There were fewer than 20% patients who never smoked, and the proportions of current smokers among OVS patients and COPD only patients were 56.3% and 48.0%, respectively.…”

BackgroundObstructive sleep apnea (OSA) is prevalent in chronic obstructive pulmonary disease (COPD). Underweight and overweight have paradoxical effect on COPD prognosis, while obesity is a risk factor for OSA. We aimed to examine the association between BMIs and OSA risk in COPD patients. MethodsThis cross-section study included 1637 COPD subjects in the final analysis. BMI was classified into different groups. OSA was defined as varying severity by AHI. The associations between BMIs and risks of diverse severity of OSA were examined. ResultsFor varying severity of OSA, obesity associated with higher risk, while normal weight group associated with lower risk; overweight had no differences and underweight group had lower risk of moderate-to-severe OSA. Compared with normal weight, for OSA, the overweight group showed a trend of high risk whereas the underweight group indicated a higher risk (OR 1.424, 95% CI 1.015-1.988) (multivariable adjusted). BMI exhibited a J-shaped association with OSA; the risk for OSA was relatively flat at BMIs of 20-24 kg/m2 and above or below the risk increased (P for non-linearity 0.0057); for severe OSA, the plot depicted a S-shaped relation, the risk reached the lowest around 24 kg/m2 and then increased thereafter (P for non-linearity 0.0200). ConclusionsIn COPD population, for various severity of OSA, obesity is a firmly risk factor, overweight not influence the risk, while normal weight associate with lower risk; compared with normal weight, underweight increased the risk for OSA; BMI had a J-shaped association with OSA and a S-shaped with severe OSA.

“…Snoring is an age- and gender-dependent phenomenon and affects 40% of the adult population [ 1 , 2 ]. According to the International Classification of Sleep Disorders (ICSD-3), snoring is ranked among the sleep-related breathing disorders [ 3 ] and frequently acts as a symptom of obstructive sleep apnea (OSA) or the upper airway resistance syndrome (UARS) [ 2 , 4 , 5 ]. OSA has been associated with serious health implications like daytime sleepiness and increased risk of accidents, pulmonary hypertension, heart failure, stroke, diabetes mellitus and depression.…”

“…Given the fact that OSA is commonly underdiagnosed and most patients with critical symptoms do not discuss them with their primary care physician [ 10 , 11 ], a screening of patients for snoring seems reasonable. The American Academy of Sleep Medicine recommends a screening for patients with obesity, family history of OSA, mandibular retrognathia and other known OSA comorbidities [ 5 ]. Mandibular retrognathia is diagnosed and treated by dentists and orthodontists.…”

About 40% of the adult population is affected by snoring, which is closely related to obstructive sleep apnea (OSA) and can be associated with serious health implications. Commercial smartphone applications (apps) offer the possibility of monitoring snoring at home. However, the number of validation studies addressing snoring apps is limited. The purpose of the present study was to assess the accuracy of recorded snoring using the free version of the app SnoreLab (Reviva Softworks Ltd., London, United Kingdom) in comparison to a full-night polygraphic measurement (Miniscreen plus, Löwenstein Medical GmbH & Co., KG, Bad Ems, Germany). Nineteen healthy adult volunteers (4 female, 15 male, mean age: 38.9 ± 19.4 years) underwent simultaneous polygraphic and SnoreLab app measurement for one night at home. Parameters obtained by the SnoreLab app were: starting/ending time of monitoring, time in bed, duration and percent of quiet sleep, light, loud and epic snoring, total snoring time and Snore Score, a specific score obtained by the SnoreLab app. Data obtained from polygraphy were: starting/ending time of monitoring, time in bed, total snoring time, snore index (SI), snore index obstructive (SI obstructive) and apnea-hypopnea-index (AHI). For different thresholds of percentage snoring per night, accuracy, sensitivity, specificity, positive and negative predictive values were calculated. Comparison of methods was undertaken by Spearman-Rho correlations and Bland-Altman plots. The SnoreLab app provides acceptable accuracy values measuring snoring >50% per night: 94.7% accuracy, 100% sensitivity, 94.1% specificity, 66.6% positive prediction value and 100% negative prediction value. Best agreement between both methods was achieved in comparing the sum of loud and epic snoring ratios obtained by the SnoreLab app with the total snoring ratio measured by polygraphy. Obstructive events could not be detected by the SnoreLab app. Compared to polygraphy, the SnoreLab app provides acceptable accuracy values regarding the measurement of especially heavy snoring.

“…These attacks are associated with frequent desaturations of oxyhemoglobin and sleep interruptions. Severity of OSA according to apnea-hypopnea index [AHI] divided into: Mild OSA: AHI ≥ 5 and <15/h, Moderate OSA: AHI ≥ 15 and <30/h and Severe OSA: AHI ≥ 30/h [2] .…”

Background: Obstructive sleep apnea (OSA) is a common and challenging health problem, especially in adults, as it is the second most common disease related to sleep. Surgical treatment plays an important role in management of OSA. However, the optimal procedure is not yet determined. Aim of the work: To compare between modified hyoid bone suspension and midline glossectomy in management of OSA due to hypopharyngeal obstruction. Patients and Methods: 40 patients with OSA due to hypopharyngeal obstruction were randomly assigned to either modified hyoid bone suspension (group A; 20 patients) or midline glossectomy (group B; 20 patients). All had been assessed by full history, clinical examination and Lab investigations and underwent pre-assigned surgical intervention. Indicators of OSA such as minimal oxygen saturation, Apnea hypopnea Index [AHI] and Epworth Sleepiness Scale [ESS] had been measured preoperatively and 6 months after surgery. Results: The studied groups were comparable as patient characteristics and preoperative data. However, hyoid suspension was associated with significant decrease of AHI [16.67±6.06 vs 20.72±4.41] and ESS [9.10±2.42 vs 11.20±2.33]. Also, minimal oxygen saturation improved significantly in group A than group B. The percentage of responders increased significantly in group A (75.0% vs 40.0% respectively). Conclusion: Modified hyoid suspension is superior than the midline glossectomy, as a safer and more effective procedure for treatment of OSA due to hypopharyngeal obstruction.
