Comparative Study
Assessing health-related quality of life in patients with restless legs syndrome in Korea: comparison with other chronic medical diseases.
There have been few quality of life (QoL) studies of patients with restless legs syndrome (RLS) in Asian countries. We studied the QoL of patients with RLS and compared it to normal controls and patients with hypertension, type 2 diabetes, or osteoarthritis in Korea. ⋯ These findings show that RLS has a considerable impact on the QoL of Koreans, which is comparable with studies of western countries. The QoL impairment relates to the degree of depression with RLS for Koreans.

Some epidemiological data are available on the association between sleep duration and sleep quality, sleep complaints, and the aging related cognitive impairment in the elderly. In this study we examined a large sample of healthy elderly subjects to assess the relationship between sleep quality, subjective cognitive complaints, and neuropsychological performance. ⋯ Our results suggest that in healthy elderly subjects, subjective sleep quality and duration did not significantly affect subjective and objective cognitive performances, except the attention level, for that the interference of sleep medication should be considered.

Review Meta Analysis
Acupressure, reflexology, and auricular acupressure for insomnia: a systematic review of randomized controlled trials.
Previous randomized controlled trials (RCTs) have shown that acupuncture may be efficacious for insomnia. Instead of needling, acupressure, reflexology, and auricular acupressure are procedures involving physical pressure on acupoints or reflex areas. These variants of acupuncture are gaining popularity, perhaps due to their non-invasive nature. ⋯ Studies that compared auricular acupressure and sham control showed equivocal results. It was also found that acupressure, reflexology, or auricular acupressure as monotherapy or combined with routine care was significantly more efficacious than routine care or no treatment. Owing to the methodological limitations of the studies and equivocal results, the current evidence does not allow a clear conclusion on the benefits of acupressure, reflexology, and auricular acupressure for insomnia.

Women with premenstrual dysphoric disorder (PMDD) experience disturbed mood, altered melatonin circadian rhythms, and frequent reports of insomnia during the luteal phase (LP) of their menstrual cycle. In this study we aimed to investigate nocturnal polysomnographic (PSG) sleep across the menstrual cycle in PMDD women and controls. ⋯ PMDD women who experience insomnia during LP had decreased melatonin secretion and increased SWS compared to controls. The sleep and melatonin findings in PMDD women may be functionally linked. Results also suggest an altered homeostatic regulation of the sleep-wake cycle in PMDD, perhaps implicating melatonin in the homeostatic process of sleep-wake regulation.

Sleep disturbance is common during critical illness, yet little is known about its prevalence or role in post-discharge quality of life among high-risk acute lung injury (ALI) patients. ⋯ Post-discharge insomnia symptoms were common and significantly associated with physical quality of life impairment among six-month ALI survivors, even after adjustment for PTSD and depression symptoms. Further studies are needed to validate these results and to characterize sleep disturbance after ALI using sleep-specific metrics.
