Automatic sleep/wake identification from wrist activity.
The purpose of this study was to develop and validate automatic scoring methods to distinguish sleep from wakefulness based on wrist activity. Forty-one subjects (18 normals and 23 with sleep orExpand
Mortality associated with sleep duration and insomnia.
Patients can be reassured that short sleep and insomnia seem associated with little risk distinct from comorbidities, and Slight risks associated with 8 or more hours of sleep and sleeping pill use need further study. Expand
Reliability and validity of the Women's Health Initiative Insomnia Rating Scale.
Findings suggest that a between-group mean difference of approximately 0.50 of a standard deviation on the WHIIRS may be clinically meaningful. Expand
The role of actigraphy in the evaluation of sleep disorders.
The data suggest that actigraphy, despite its limitations, may be a useful, cost-effective method for assessing specific sleep disorders, such as insomnia and schedule disorders, and for monitoring their treatment process. Expand
Suggestive evidence for association of the circadian genes PERIOD3 and ARNTL with bipolar disorder
Haplotypes in ARNTL and PER3 were found to be significantly associated with BPAD via single‐gene permutation tests and are suggestive of their involvement in bipolar disorder and warrant further study in a larger sample. Expand
Circadian polymorphisms associated with affective disorders
Findings suggest that perturbations of the circadian gene network at several levels may influence mood disorders, perhaps ultimately through regulation of MAOA and its modulation of dopamine transmission. Expand
Twenty-four-hour intraocular pressure pattern associated with early glaucomatous changes.
The diurnal IOP is higher, the diurnal-to-nocturnal change of habitual Iop is less, and the posture-independent IOP pattern around normal awakening time is different in eyes with early glaucomatous changes. Expand
Sleep estimation from wrist movement quantified by different actigraphic modalities
Sleep--wake estimates from nocturnal wrist activity quantified by different motion-quantifying algorithms were compared, suggesting that the transducers of these two devices performed comparably for monitoring sleep and wakefulness. Expand
Criterion validity of the Pittsburgh Sleep Quality Index: Investigation in a non-clinical sample
The PSQI has good internal homogeneity, but may be less reflective of actual sleep parameters than a negative cognitive viewpoint or pessimistic thinking, and the sleep complaints measured may often be more indicative of general dissatisfaction than of any specifically sleep-related disturbance.

Sleep-disordered breathing in community-dwelling elderly.
Body mass index, falling asleep at inappropriate times, male gender, no alcohol within 2 hr of bedtime and napping were the best predictors of sleep-disordered breathing. Expand
