The objective of this secondary analysis was to evaluate concurrent validity of actigraphy and polysomnography (PSG) in older women with insomnia. ⋯ Actigraphy offers a relatively inexpensive and unobtrusive method for measuring sleep, but it appears to underestimate sleep disturbance, particularly at sleep efficiency levels below 73%, in older women with insomnia.

To evaluate the current state of sleep medicine educational resources and training offered by US neurology residency programs. ⋯ This is the first report providing an analysis of the current state of sleep medicine training in US Neurology Residency Programs. Our data provide evidence that investment by the residency program in sleep education may enhance the ultimate decision by the neurology trainee to pursue a career in sleep medicine.

Review Meta Analysis
Effect of oral appliances on blood pressure in obstructive sleep apnea: a systematic review and meta-analysis.
Obstructive sleep apnea (OSA) is an independent risk factor for the development of hypertension. However the effect of continuous positive airway pressure (CPAP) on lowering systemic blood pressure (BP) in OSA patients has been conflicting. Oral appliance (OA) therapy is an important alternative therapy to CPAP for patients with mild to moderate OSA. ⋯ The pooled estimate shows a favorable effect of OAs on SBP, MAP, and DBP. Most of the studies were observational. Therefore, more RCTs are warranted involving a larger number of patients and longer treatment periods to confirm the effects of OA on BP.

Multicenter Study Comparative Study
Nightmares and dysfunctional beliefs about sleep mediate the effect of insomnia symptoms on suicidal ideation.
Many studies have reported a positive association between sleep problems and suicidal ideation. Some prospective studies in the elderly have shown that insomnia is a risk factor for suicide death after controlling for other depressive symptoms. However, hypotheses to explain how this risk is mediated have not previously been assessed. We tested the hypothesis that insomnia symptoms are related to suicidal ideation through mediation by dysfunctional beliefs and attitudes about sleep and/or nightmares. ⋯ Nightmares as well as dysfunctional beliefs and attitudes about sleep each are positively and independently related to the intensity of suicidal ideation, and the effect of insomnia symptoms appears to be mediated through these two variables.

Comparative Study
Evaluation of a single-channel nasal pressure device to assess obstructive sleep apnea risk in laboratory and home environments.
To evaluate the sensitivity and specificity of a portable single-channel (intra-nasal pressure) sleep apnea device (ApneaLink) in both the laboratory and at home for assessment of sleep apnea risk in comparison with standard polysomnography (PSG). ⋯ The ApneaLink demonstrated good sensitivity and specificity in quantifying AHI when compared to PSG in a population with and without confirmed OSA. This simple, easy-to-use device may be useful in de novo large-scale occupational or underserved community OSA diagnostic programs to identify those with unambiguous disease who need immediate treatment or indicate those who may be at increased risk of OSA.
