Comparative Study
A quantitative approach to distinguishing older adults with insomnia from good sleeper controls.
Establishing quantitative criteria to distinguish individuals with and without insomnia is important for clinical and research applications, but consensus has not yet been reached for specific values. The purpose of this study was to identify the optimal quantitative thresholds for actigraphy and sleep diary that differentiate older adults (> 60 years) with insomnia from good sleeper controls. ⋯ Sleep diary parameters discriminated individuals with insomnia from good sleepers more accurately than actigraphy. These quantitative criteria are similar to those reported by other investigators using different methods and samples, including younger adults. The results suggest that the sleep diary, an inexpensive self-report sleep measure, may be used in clinical and research settings to help distinguish older adults with and without insomnia.

Randomized Controlled Trial Multicenter Study Comparative Study
CPAP and hypertension in nonsleepy patients.
Is continuous positive airway pressure (CPAP) therapy better than no therapy in reducing the incidence of hypertension or cardiovascular (CV) events in a cohort of nonsleepy patients with obstructive sleep apnea (OSA)? ⋯ Instituto de Salud Carlos III (PI 04/0165) (Fondo de Investigaciones Sanitarios, Ministerio de Sanidad y Consumo, Spain), Spanish Respiratory Society (SEPAR) (Barcelona), Resmed (Bella Vista, Australia), Air Products-Carburos Metalicos (Barcelona), Respironics (Murrysville, Pennsylvania), and Breas Medical (Madrid, Spain).

Comparative Study
Morbidity prior to a diagnosis of sleep-disordered breathing: a controlled national study.
Sleep-disordered breathing (SDB) causes burden to the sufferer, the healthcare system, and society. Most studies have focused on cardiovascular diseases (CVDs) after a diagnosis of obstructive sleep apnea (OSA) or obesity hypoventilation syndrome (OHS); however, the overall morbidity prior to an SDB diagnosis has not been evaluated. The aim of this study was to identify morbidity prior to a SDB diagnosis to identify patients at risk for having/developing SDB. ⋯ Patients with SDB show significant morbidities several years prior to a diagnosis of OSA or OHS. OSA should be considered in all medical specialties as an important comorbidity. In our study, evidence points to particular emphasis for considering this diagnosis in endocrinology and metabolic specialties.

Although disturbed sleep has been frequently reported in patients with seizures, little is known about insomnia and epilepsy. The aims of this study were (1) to analyze the prevalence and degree of insomnia in patients with epilepsy, (2) to examine the clinical features and correlates of insomnia in these patients, and (3) to evaluate the impact of poor sleep on their quality of life. ⋯ These results suggest that insomnia and poor sleep are common in patients with epilepsy and may adversely impact quality of life. Further studies should examine whether improvements in sleep can improve seizure control and quality of life of these patients.
