Comparative Study
Simplifying STOP-BANG: use of a simple questionnaire to screen for OSA in an Asian population.
We aim to assess the utility of a simple-to-use 8-point questionnaire in screening for moderate-severe obstructive sleep apnea (OSA) and to assess the validity of cutoffs used to score body mass index (BMI) in this questionnaire. ⋯ STOP-BANG is a clinically useful tool with high sensitivity that can be used to screen patients for moderate and severe OSA. Using cutoffs of 30 for BMI, 40 cm for neck circumference, and 50 years for age simplifies the application of the tool without affecting performance.

Current screening for obstructive sleep apnea (OSA) emphasizes self-reported snoring and other breathing symptoms. Nocturia, a symptom with a precise pathophysiological link to sleep apnea, has not been assessed as a screening tool for this common disorder of sleep respiration. In a large sample of adults presenting to area sleep centers, we aimed to determine the predictive power of nocturia for OSA and compare findings with other markers of OSA commonly used to screen for this disease. ⋯ Nocturia appears comparable to snoring as a screening tool for OSA in patients presenting to a sleep medical center. Research in urology and primary care clinics is needed to definitively clarify the use of nocturia as a screening instrument for obstructive sleep apnea.

Evidence suggests that obesity hypoventilation syndrome (OHS) is underrecognized and undertreated. Aim of this study was to evaluate the prevalence and clinical characteristics of OHS among patients reporting sleep-related breathing disorders in northern Greece. ⋯ In our study population, OHS was accounted for a significant percentage of the patients with reported breathing disorders in sleep. As obesity has become an international epidemic, it is crucial that physicians have the ability to recognize and treat obesity-associated diseases.

The frequency of obstructive sleep apnea-hypopnea syndrome (OSAHS) in patients with idiopathic pulmonary fibrosis (IPF) remains controversial. The aim of this study was to assess the frequency of OSAHS in newly diagnosed IPF patients and to identify possible correlations with body mass index and pulmonary function testing parameters. ⋯ Sleep-disordered breathing seems frequent, although remains usually under diagnosed in IPF patients. A decrease in TLC, reflecting the severity of pulmonary restriction, might predispose IPF patients in SDB, especially during the vulnerable REM sleep period.
