Randomized Controlled Trial
Stage-matched intervention for adherence to CPAP in patients with obstructive sleep apnea: a randomized controlled trial.
The objective of the study was to evaluate the effectiveness of stage-matched intervention on adherence to continuous positive airway pressure (CPAP) in patients with obstructive sleep apnea syndrome. ⋯ Stage-matched intervention could not only facilitate intention formation and enhance treatment self-efficacy but significantly improve CPAP adherence in OSA patients for the 3-month treatment.

Is portable monitoring for diagnosing obstructive sleep apnea syndrome suitable in elderly population?
Obstructive sleep apnea syndrome (OSAS) is highly prevalent in the elderly. Unattended, at-home portable monitoring (PM) is a diagnostic alternative to polysomnography in adults with high clinical probability of OSAS. However, no studies have evaluated the diagnostic accuracy of PM in elderly population. The aim of our study was to evaluate the effectiveness of PM in elderly patients. ⋯ PM was effective for diagnosing OSAS in the elderly and can be used as an alternative to PSG in elderly patients with a high clinical probability of OSAS.

Obstructive sleep apnea (OSA) is a common medical disorder affecting at least 2 % of women and 4 % of men living in Western societies. Obesity, older age, male gender, alcohol and sedative use, smoking, craniofacial parameters, and volume overload are some of the risk factors for this disorder. ⋯ Hemodialysis and renal transplantation can markedly improve the severity of OSA in patients with concomitant kidney disease. Finally, there is a potential of a vicious cycle between OSA and fluid overload disorders, whereby OSA can contribute to the pathogenesis of arterial hypertension, heart failure, and chronic kidney disease, which in turn will significantly contribute to the course OSA.

The Berlin Questionnaire (BQ) is a useful tool to identify the high-risk group for obstructive sleep apnea (OSA) in the primary care sites or hospital, but the usefulness of the BQ to identify the high-risk group for OSA in the general population has not been evaluated. The purpose of our study was to develop the Korean version of the BQ (KBQ) and evaluate the usefulness of the BQ in identifying patients with OSA in the general population. ⋯ This is the first study to confirm the usefulness of the BQ as a screening tool for OSA by prioritizing subjects at high risk for OSA in the general population.

Attempts to understand the causes of cognitive impairment in obstructive sleep apnea (OSA) are complicated by the overlap among clinical and demographic factors that may impact cognition. The goal of the current study was to isolate the contribution of hypoxemia to cognitive impairment in OSA. ⋯ This study is one of the first to compare the cognitive performance of patients with high and low hypoxemia after controlling for demographic factors and aspects of OSA severity that could confound the relationship. In our carefully matched sample, we observed an unexpected advantage of higher hypoxemia on memory. These preliminary findings are discussed in the context of basic science literature on the protective effects of adaptation to intermittent hypoxemia. Our data suggest that the association between hypoxemia and cognition may not straightforward. Future research targeting the effects of hypoxemia on cognition controlling for other clinical factors in large groups of patients with OSA will be important.
