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.

This study evaluated the prevalence of, and the risk factors for, obstructive sleep apnea syndrome (OSAS) among Brazilian railroad workers. ⋯ The prevalence of OSAS in Brazilian railroad workers was higher than that observed in the general population but similar to that found in the population of the city of São Paulo, Brazil. These results suggest that age, BMI, a high risk of developing apnea through subjective self-reporting (Berlin), and alcohol use are associated with a higher risk of developing OSAS. These data reinforce the need to be more attentive to this population because they have a higher propensity for accidents.

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.

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.
