Docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA)-omega-3 fatty acids with various functions-influence sleep in children and young adults. However, only limited studies on their effects on sleep in middle- and old-aged adults have been reported. Therefore, we investigated the effects of DHA and EPA on sleep quality in subjects aged ≥ 45 years. We performed a randomized, placebo-controlled, double-blinded, parallel-grouped study, in which we randomly assigned 66 healthy Japanese males and females. Each individual received six 480 mg capsules containing 576 mg DHA and 284 mg EPA per day (DHA/EPA group, = 33), or corn oil (placebo group, = 33), for 12 weeks. Before and after the intervention, the Oguri-Shirakawa-Azumi sleep inventory MA version (OSA-MA) and the sleep state test were conducted. In the DHA/EPA group, factor III (frequent dreaming) scores among the OSA-MA scores were significantly improved compared to the placebo group. Additionally, sleep state tests revealed that sleep efficiency improved in the DHA/EPA group. To our knowledge, this study is the first to report that DHA/EPA improves sleep quality in middle- and old-aged individuals, even at doses lower than those administered in previous studies.

Atopic dermatitis (AD), a common chronic inflammatory skin disorder is characterized by a complex pathology with skin-barrier abnormalities, immune dysregulation, and microbial dysbiosis. Patients' quality of life is often negatively impacted by persistent pruritus, sleep disturbance, and recurrent skin infections. In addition, patients may have comorbid atopic as well as nonatopic diseases.

Obstructive sleep apnea (OSA) is widespread, under-recognized, and under-treated, impacting the health and quality of life for millions. The current gold standard for sleep apnea testing is based on the in-lab sleep study, which is costly, cumbersome, not readily available and represents a well-known roadblock to managing this huge societal burden. Assessment of neuromuscular function involved in the upper airway using electromyography (EMG) has shown potential to characterize and diagnose sleep apnea, while the development of transmembranous electromyography (tmEMG), a painless surface probe, has made this opportunity practical and highly feasible.

Introduction: Sciatica is a debilitating condition that often becomes chronic, and for which there are few effective treatment options. Treatments such as the anti-depressant duloxetine have shown promise, but the evidence is inconclusive. We are describing a high quality, definitive trial to investigate the efficacy, safety and cost-effectiveness of duloxetine in chronic sciatica.

This study aimed to improve our understanding of sleep problems as a comorbidity of hereditary deaf-blindness due to Usher syndrome type 2a. Fifteen patients with Usher syndrome type 2a with a conclusive genetic diagnosis and 15 unaffected controls participated in comprehensive sleep and activity assessments for 2 weeks, using the MotionWatch 8 actigraph and consensus sleep diary. Various sleep parameters including sleep opportunity window, sleep latency, sleep efficiency, and self-reported sleep quality were analysed.
