Elevated economic burden in obstructive lung disease patients with concomitant sleep apnea syndrome.
The purpose of this study is to examine the incremental economic burden of sleep apnea syndrome (SAS) among individuals with concomitant asthma, chronic obstructive pulmonary disease (COPD), or both (i.e., asthma/COPD). ⋯ SAS may add additional economic burden on beneficiaries who already have COPD or asthma/COPD.

Evaluation of a portable recording device (ApneaLink) for case selection of obstructive sleep apnea.
This study was designed to assess the sensitivity and specificity of a portable sleep apnea recording device (ApneaLink) using standard polysomnography (PSG) as a reference and to evaluate the possibility of using the ApneaLink as a case selection technique for patients with suspected obstructive sleep apnea (OSA). ⋯ The ApneaLink is an ambulatory sleep monitor that can detect OSA and/or hypopnea with acceptable reliability. The screening and diagnostic capability needs to be verified by further evaluation and manual scoring of the ApneaLink. It could be a better choice than traditional oximetry in terms of recording respiratory events, although severity may be under- or overestimated.

Primary care is central for the diagnosis and treatment of obstructive sleep apnea (OSA). The aim of this study was to estimate the prevalence of symptoms and risk of OSA in primary care in Jordan. ⋯ Obstructive sleep apnea, snoring, and daytime sleepiness were common among Jordanian patients attending primary care clinics. More attention to OSA is needed in primary care, and patients at risk should be referred for further evaluation.

The purpose of this study was to investigate apnea-hypopnea index (AHI) across two polysomnographies (PSGs) to examine AHI variability and impact on clinical diagnosis. ⋯ Utilizing a large patient population, this study supports the significant night-to-night variability in PSG respiratory variables. Identification of sleep apnea in some patients is reduced when sleep experts are provided with only one PSG recording. The clinical implication is that about 13% of sleep clinic patients might benefit from a second night of PSG.

To develop an intermittent hypoxia/reoxygenation (IH/ROX) rabbit carotid artery model and then investigate the inflammation status of rabbit carotid artery endothelium after IH exposure and its relationship with leptin. ⋯ IH/ROX activated the inflammation pathway significantly in the endothelium, which was more intensive than CH and intensity-dependent. When exposed to both IH/ROX and leptin, inflammation occurs more dramatically. It means that synergic activating roles were performed by IH/ROX and leptin. This study may have a clinical implication that IH can cause endothelial damage through activated inflammation in OSA patients, and if the OSA patients have obesity at the same time, the endothelial damage or the inflammation would be more significant because of elevated leptin level as a synergic factor.
