Phase-amplitude coupling (PAC) across frequency might be associated with the long-range synchronization of brain networks, facilitating the spatiotemporal integration of multiple cell assemblies for information transmission during inhibitory control. However, sleep problems may affect these cortical information transmissions based on cross-frequency PAC, especially when humans work in environments of social isolation. This study aimed to evaluate changes in the theta-beta/gamma PAC of task-related electroencephalography (EEG) for humans with insufficient sleep. Here, we monitored the EEG signals of 60 healthy volunteers and 18 soldiers in the normal environment, performing a Go/Nogo task. Soldiers also participated in the same test in isolated cabins. These measures demonstrated theta-beta PACs between the frontal and central-parietal, and robust theta-gamma PACs between the frontal and occipital cortex. Unfortunately, these PACs significantly decreased when humans experienced insufficient sleep, which was positively correlated with the behavioral performance of inhibitory control. The evaluation of theta-beta/gamma PAC of Go/Nogo task-related EEG is necessary to help understand the different influences of sleep problems in humans.

跨频率的相位振幅耦合(PAC)可能与大脑网络的远程同步有关,促进了抑制控制过程中多个细胞组件的时空整合以传递信息。然而,睡眠问题可能会影响这些基于交叉频率PAC的皮质信息传输,特别是当人们在社会隔离的环境中工作时。本研究旨在评估睡眠不足的人在任务相关脑电图(EEG)中β - β / γ PAC的变化。在这里,我们监测了60名健康志愿者和18名在正常环境下执行Go/Nogo任务的士兵的脑电图信号。士兵们也在孤立的小木屋里参加了同样的测试。这些测量表明前额和中央顶叶皮层之间有β - PACs,前额和枕叶皮层之间有强大的β - PACs。不幸的是,当人类睡眠不足时,这些pac显著减少,这与抑制控制的行为表现呈正相关。评估Go/Nogo任务相关脑电图的theta-beta/gamma PAC对于帮助理解人类睡眠问题的不同影响是必要的。

Worldwide, approximately one in three people are myopic or short-sighted. Myopia in children is of particular concern as younger onset age implies a higher risk of progression, and consequently greater risk of developing vision-threatening complications. The importance of sleep in children's health has long been acknowledged, but evidence for its role in childhood myopia is fairly new and mixed results were presented across studies. To facilitate better understanding of this relationship, a broad literature search, up to and including October 31, 2022, was performed using three databases (PubMed, Embase, and Scopus). Seventeen studies were included in the review, covering four main aspects of sleep, namely duration, quality, timing, and efficiency, and their associations with myopia in children. The present literature review discussed these studies, revealed potential limitations in their methodologies, and identified gaps that need to be addressed in the future. The review also acknowledges that current evidence is insufficient, and the role of sleep in childhood myopia is far from being fully understood. Future studies that primarily, objectively, and accurately assess sleep and myopia, taking other characteristics of sleep beyond duration into consideration, with a more diverse sample in terms of age, ethnicity, and cultural/environmental background, and control for confounders such as light exposure and education load are much needed. Although more research is required, myopia management should be a holistic approach and the inclusion of sleep hygiene in myopia education targeting children and parents ought to be encouraged.

在世界范围内,大约三分之一的人是近视或近视。儿童近视尤其值得关注,因为发病年龄越小,进展的风险就越大,因此出现威胁视力的并发症的风险也越大。睡眠对儿童健康的重要性早已得到承认,但它在儿童近视中的作用的证据是相当新的,各种研究的结果不一。为了更好地理解这种关系,我们使用三个数据库(PubMed、Embase和Scopus)进行了广泛的文献检索,检索时间截止到2022年10月31日。这篇综述包括17项研究,涵盖了睡眠的四个主要方面,即持续时间、质量、时间和效率,以及它们与儿童近视的关系。目前的文献综述讨论了这些研究,揭示了其方法的潜在局限性,并确定了未来需要解决的差距。该综述还承认,目前的证据不足,睡眠在儿童近视中的作用还远未被完全了解。未来的研究需要主要、客观、准确地评估睡眠和近视,考虑睡眠持续时间以外的其他特征,在年龄、种族、文化/环境背景方面采用更多样化的样本,并控制光照和教育负荷等混杂因素。虽然还需要更多的研究,但近视管理应该是一个整体的方法,应该鼓励将睡眠卫生纳入针对儿童和家长的近视教育中。

Study objectives: Sleep-related adverse effects during acute treatment with antidepressants undermine adherence and impede remission. We aimed to address subtypes of sleep-related adverse effects and depict the relationship between dose and sleep-related adverse events.

Methods: We searched PubMed, Embase, Cochrane Central Register of Controlled Trials, and Web of Science for double-blind randomized controlled trials of depression published before April 30th, 2023. Eligible studies reporting sleep-related adverse effects during short-term monotherapy were included. The odds ratios (ORs) for sleep-related adverse effects were addressed with network meta-analysis. A Bayesian approach was used to depict the dose-effect relationship. Heterogeneity among studies was assessed using the τ2 and I2 statistics. Sensitivity analyses were performed without studies featuring high risk of bias.

Results: Studies with 64 696 patients were examined from 216 trials. Compared to placebo, 13 antidepressants showed higher ORs for somnolence, of which fluvoxamine (OR = 6.32; 95% CI: 3.56 to 11.21) ranked the top. Eleven had higher risks for insomnia, reboxetine ranked the top (OR = 3.47; 95% CI: 2.77 to 4.36). The dose-effect relationships curves between somnolence or insomnia and dose included linear shape, inverted U-shape, and other shapes. There was no significant heterogeneity among individual studies. The quality of evidence for results in network meta-analyses was rated as very low to moderate by Grading of Recommendations Assessment, Development, and Evaluation.

Conclusions: Most antidepressants had higher risks for insomnia or somnolence than placebo. The diverse relationship curves between somnolence or insomnia and dose of antidepressants can guide clinicians to adjust the doses. These findings suggest clinicians pay more attention to sleep-related adverse effects during acute treatment with antidepressants.

研究目的:抗抑郁药急性治疗期间与睡眠相关的不良反应会破坏依从性并阻碍病情缓解。我们旨在解决睡眠相关不良反应的亚型,并描述剂量与睡眠相关不良事件之间的关系。方法:我们检索了PubMed、Embase、Cochrane Central Register of Controlled Trials和Web of Science在2023年4月30日之前发表的抑郁症双盲随机对照试验。纳入了报告短期单药治疗期间睡眠相关不良反应的合格研究。睡眠相关不良反应的比值比(OR)通过网络荟萃分析进行处理。使用贝叶斯方法来描述剂量-效应关系。使用τ2和I2统计来评估研究之间的异质性。进行敏感性分析时没有进行具有高偏倚风险的研究。结果:对216项试验中的64696名患者进行了研究。与安慰剂相比,13种抗抑郁药表现出更高的嗜睡ORs,其中氟伏沙明(OR=6.32;95%CI:3.56至11.21)位居榜首。11人失眠风险较高,瑞波西汀排在首位(OR=3.47;95%CI:2.77~4.36)。嗜睡或失眠与剂量之间的量效关系曲线包括线性、倒U形和其他形状。个体研究之间没有显著的异质性。网络荟萃分析结果的证据质量被建议评估、发展和评估分级评定为极低至中等。结论:大多数抗抑郁药比安慰剂有更高的失眠或嗜睡风险。嗜睡或失眠与抗抑郁药剂量之间的不同关系曲线可以指导临床医生调整剂量。这些发现表明临床医生在抗抑郁药的急性治疗过程中更加关注睡眠相关的不良反应。

Study objectives: To compare the 24-hour sleep assessment capabilities of two contactless sleep technologies (CSTs) to actigraphy in community-dwelling older adults.

Methods: We collected 7-14 days of data at home from 35 older adults (age: 65-83), some with medical conditions, using Withings Sleep Analyser (WSA, n = 29), Emfit QS (Emfit, n = 17), a standard actigraphy device (Actiwatch Spectrum [AWS, n = 34]), and a sleep diary (n = 35). We compared nocturnal and daytime sleep measures estimated by the CSTs and actigraphy without sleep diary information (AWS-A) against sleep-diary-assisted actigraphy (AWS|SD).

Results: Compared to sleep diary, both CSTs accurately determined the timing of nocturnal sleep (intraclass correlation [ICC]: going to bed, getting out of bed, time in bed >0.75), whereas the accuracy of AWS-A was much lower. Compared to AWS|SD, the CSTs overestimated nocturnal total sleep time (WSA: +92.71 ± 81.16 minutes; Emfit: +101.47 ± 75.95 minutes) as did AWS-A (+46.95 ± 67.26 minutes). The CSTs overestimated sleep efficiency (WSA: +9.19% ± 14.26%; Emfit: +9.41% ± 11.05%), whereas AWS-A estimate (-2.38% ± 10.06%) was accurate. About 65% (n = 23) of participants reported daytime naps either in bed or elsewhere. About 90% in-bed nap periods were accurately determined by WSA while Emfit was less accurate. All three devices estimated 24-hour sleep duration with an error of ≈10% compared to the sleep diary.

Conclusions: CSTs accurately capture the timing of in-bed nocturnal sleep periods without the need for sleep diary information. However, improvements are needed in assessing parameters such as total sleep time, sleep efficiency, and naps before these CSTs can be fully utilized in field settings.

研究目的:比较两种非接触式睡眠技术(CST)与活动描记术在社区老年人中的24小时睡眠评估能力。方法:我们在家中收集了35名老年人(年龄:65-83岁)7-14天的数据,其中一些人患有疾病,使用Withings睡眠分析仪(WSA,n=29)、Emfit QS(Emfit,n=17)、标准活动描记设备(Actiwatch Spectrum[AWS,n=34])和睡眠日记(n=35)。我们将CST和无睡眠日记信息的活动描记术(AWS-A)估计的夜间和日间睡眠测量值与睡眠日记辅助活动描记法(AWS|SD)进行了比较。结果:与睡眠日记相比,两种CST都准确地确定了夜间睡眠的时间(组内相关性[ICC]:上床、起床、上床时间>0.75),而AWS-A的准确性要低得多。与AWS|SD相比,CST高估了夜间总睡眠时间(WSA:+92.71±81.16分钟;Emfit:+101.47±75.95分钟),AWS-A(+46.95±67.26分钟)也是如此。CST高估了睡眠效率(WSA:+9.19%±14.26%;Emfit:+9.41%±11.05%),而AWS-A估计值(-2.38%±10.06%)是准确的。大约65%(n=23)的参与者报告白天在床上或其他地方小睡。大约90%的床上小睡时间是由WSA准确确定的,而Emfit则不那么准确。这三种设备都估计了24小时的睡眠时间,与睡眠日记相比,误差约为10%。结论:CST可以准确地捕捉床上夜间睡眠时间,而无需睡眠日记信息。然而,在现场设置中充分利用CST之前,需要改进评估参数,如总睡眠时间、睡眠效率和小睡。

Study objectives: Despite the negative impact of poor sleep on mental health, evidence-based insomnia management guidelines have not been translated into routine mental healthcare. Here, we evaluate a state-wide knowledge translation effort to disseminate sleep and insomnia education to graduate psychology programs online using the RE-AIM (reach, effectiveness, adoption, implementation, and maintenance) evaluation framework.

Methods: Using a non-randomized waitlist control design, graduate psychology students attended a validated 6-hour online sleep education workshop delivered live as part of their graduate psychology program in Victoria, Australia. Sleep knowledge, attitudes, and practice assessments were conducted pre- and post-program, with long-term feedback collected at 12 months.

Results: Seven out of ten graduate psychology programs adopted the workshop (adoption rate = 70%). The workshop reached 313 graduate students, with a research participation rate of 81%. The workshop was effective at improving students' sleep knowledge and self-efficacy to manage sleep disturbances using cognitive behavioral therapy for insomnia (CBT-I), compared to the waitlist control with medium-to-large effect sizes (all p < .001). Implementation feedback was positive, with 96% of students rating the workshop as very good-to-excellent. Twelve-month maintenance data demonstrated that 83% of students had used the sleep knowledge/skills learned in the workshop in their clinical practice. However, more practical training is required to achieve CBT-I competency.

Conclusions: Online sleep education workshops can be scaled to deliver cost-effective foundational sleep training to graduate psychology students. This workshop will accelerate the translation of insomnia management guidelines into psychology practice to improve sleep and mental health outcomes nationwide.

研究目标:尽管睡眠不足对心理健康有负面影响,但循证失眠管理指南尚未转化为常规心理健康。在这里,我们使用RE-AIM(覆盖范围、有效性、采用、实施和维护)评估框架,评估了全州范围内的知识翻译工作,以在线向研究生心理学项目传播睡眠和失眠教育。方法:采用非随机等待名单对照设计,心理学研究生参加了一个经过验证的6小时在线睡眠教育研讨会,该研讨会是他们在澳大利亚维多利亚州的研究生心理学项目的一部分。睡眠知识、态度和实践评估在项目前后进行,并在12个月时收集长期反馈。结果:十分之七的心理学研究生课程采用了研讨会(采用率=70%)。研讨会有313名研究生参加,研究参与率为81%。与中等至较大效果的等待名单对照组相比,该研讨会有效地提高了学生的睡眠知识和自我效能,以使用失眠认知行为疗法(CBT-I)来管理睡眠障碍(均p<0.001)。实施反馈是积极的,96%的学生将该研讨会评为非常好至优秀。12个月的维护数据表明,83%的学生在临床实践中使用了在研讨会上学到的睡眠知识/技能。然而,要获得CBT-I能力,还需要更多的实践培训。结论:在线睡眠教育研讨会可以扩大规模,为心理学研究生提供具有成本效益的基础睡眠培训。该研讨会将加速将失眠管理指南转化为心理学实践,以改善全国范围内的睡眠和心理健康状况。

Study objectives: This study investigated alterations in resting-state functional connectivity (RSFC) and hyperarousal biomarkers in patients with chronic insomnia disorder (CID), compared with good sleepers (GS). We also examined the relationships between altered RSFC and hyperarousal biomarkers.

Methods: Fifty patients with CID and 52 GS completed self-reporting questionnaires, and then underwent polysomnography and resting-state functional magnetic resonance imaging. We analyzed RSFC in the amygdala (AMG) and anterior insula (aINS), which are core regions of the salience network that are likely to be involved in hyperarousal. We also analyzed electroencephalography (EEG) relative beta power and heart rate variability (HRV) parameters (e.g. low and high frequency) during sleep. We then tested between-group differences in the RSFC and hyperarousal biomarkers; we examined correlations of RSFC with EEG beta power and HRV.

Results: Compared with GS, patients with CID showed more negative RSFC between the right amygdala (R.AMG) and left supramarginal gyrus (L.SMG), but less positive RSFC between the left aINS and bilateral lateral prefrontal cortex. The R.AMG-L.SMG RSFC was negatively correlated with EEG beta power in central regions (C3: r = -0.336, p = 0.012; C4: r = -0.314, p = 0.024).

Conclusions: Decreased RSFC between the R.AMG and L.SMG in patients with insomnia may reflect the difficulty in cortical top-down regulation of the AMG, indicating daytime hyperarousal. Individuals who experience hyperarousal during the daytime may also exhibit cortical hyperarousal during sleep, as indicated by increased EEG beta power.

研究目的:本研究调查了与良好睡眠者(GS)相比,慢性失眠障碍(CID)患者静息状态功能连接(RSFC)和超兴奋生物标志物的变化。我们还研究了RSFC改变与超兴奋生物标志物之间的关系。方法:50例CID患者和52例GS患者完成自我报告问卷,然后进行多导睡眠图和静息状态功能磁共振成像。我们分析了杏仁核(AMG)和前脑岛(aINS)中的RSFC,这两个区域是显著性网络的核心区域,可能与过度兴奋有关。我们还分析了睡眠期间的脑电图(EEG)相对β功率和心率变异性(HRV)参数(例如低频和高频)。然后,我们测试了RSFC和超兴奋生物标志物的组间差异;结果:与GS相比,CID患者右侧杏仁核(R.AMG)和左侧缘上回(L.SMG)的RSFC呈阴性,而左侧aINS和双侧外侧前额叶皮层的RSFC阳性较少。R.AMG-L.SMG-RSFC与中心区域的EEGβ功率呈负相关(C3:R = -0.336,p = 0.012;C4:r = -0.314,p = 0.024)。结论:失眠患者R.AMG和L.SMG之间的RSFC降低可能反映了AMG的皮质自上而下调节的困难,表明白天过度兴奋。白天经历过度兴奋的个体在睡眠期间也可能表现出皮层过度兴奋,如脑电图β功率增加所示。
