Background and ObjectiveaaWe used the Symptom Checklist 90-Revised (SCL-90-R) to compare the psychosomatic symptom profiles between periodic limb movement disorder (PLMD) and restless legs syndrome (RLS) patients. MethodsaaTwenty consecutive drug-naïve RLS patients, 20 ageand sex-matched patients with PLMD and healthy controls were enrolled. Questionnaires evaluating sleep (Pittsburgh Sleep Quality Index, and Insomnia Severity Index), depression (Beck Depression Inventory II), and psychosomatic symptoms (SCL-90-R) were administered. Polysomnography was performed in the patients with PLMD or RLS. ResultsaaThe mean age of the subjects was 57.5 ± 10.9 years, and half of the subjects were male. Compared with the patients with RLS, the patients with PLMD exhibited a reduced total sleep time (276.6 ± 41.3 vs. 322.4 ± 42.9, p = 0.04) and a decreased proportion of REM sleep (12.5 ± 6.6 vs. 17.8 ± 7.8, p = 0.009). The patients with RLS exhibited higher SCL-90-R T-scores on the somatization (post hoc p < 0.001), obsessive-compulsive (post hoc p < 0.001), interpersonal sensitivity (post hoc p = 0.003), anxiety (post hoc p = 0.005), and psychoticism (post hoc p = 0.004) domains than the controls. Compared to the controls, the patients with PLMD exhibited higher SCL-90-R scores only in hostility (post hoc p = 0.016). Somatization in the RLS patients was significantly worse than that in the PLMD patients (post hoc p = 0.003). ConclusionsaaThe results of our study demonstrate that psychosomatic distress is greater in RLS patients and lesser in PLMD patients. Somatization was a distinguishing symptom between RLS and PLMD.

Research exploring the relationship between mental health difficulties and insomnia amongst students in the UK remains limited. This study further examined the extent of potential relationships between insomnia, anxiety and depression symptoms amongst university students in the UK. A sample of 487 students from four northern universities completed The Insomnia Severity Index, SLEEP-50, and Hospital Anxiety and Depression Scales. Approximately one fifth of students experienced mild to severe levels of depressive symptoms, and two thirds reported anxious symptoms. One quarter of students indicated insomnia symptoms in the clinical range, however the prevalence of sleep-disorders other than insomnia remained low ( < 5%). Finally, symptoms of insomnia and apnoea were significantly related to depression, after controlling for co-morbid anxiety. The current outcomes highlight the high prevalence of depressive and insomnia symptoms amongst university students in the UK. Considering the relationship between insomnia and depression, student- focused mental health services should explore the possibility of treating insomnia to circumvent depression.

Background and ObjectiveaaObstructive sleep apnea syndrome (OSAS) is considered to be closely related to systemic inflammation. Resistin levels have been demonstrated to be a measure of systemic inflammation. For children, salivary resistin (SR) sampling is an easy and pain-free method for sample collection and is optimal for multiple sampling. Therefore, we aimed to evaluate correlations among SR levels, objective polysomnography (PSG) parameters, and subjective sleep symptoms. MethodsaaFifty-six children who attended our clinic over 1 year were enrolled prospectively; these children underwent clinical evaluation, questionnaire studies, and PSG. SR was measured at 2 points: at night before PSG and in the early morning after PSG. resultsaaThe subjects (n = 56) were divided into the control [n = 23, apnea hypopnea index (AHI) < 1] and OSAS (n = 33, AHI ≥ 1) groups. SR levels after PSG in the OSAS and control groups were similarly higher than that before PSG. There was no significant difference in SR levels between the two groups and among the control and OSAS subgroups. SR levels in the OSAS subgroups were not related to AHI, tonsil size, AN (adenoid-nasopharyngeal) ratio, questionnaire results, lowest oxygen saturation, and oxygen desaturation index (ODI). ConclusionsaaSR levels had no significant correlation with AHI, scores of the Korean version of modified pediatric Epworth Sleepiness Scale, the lowest oxygen saturation, and ODI; SR levels exhibited diurnal variations regardless of the presence of OSAS. However, there is no consensus regarding the relationship between resistin levels and OSAS. Further studies should be pursued in the future. Sleep Med res 2018;9(2):77-82
背景与目的阻塞性睡眠呼吸暂停综合征(OSAS)被认为与全身炎症密切相关。抵抗素水平已被证明是衡量全身炎症的指标。对于儿童来说,唾液抵抗素(SR)采样是一种简单、无痛的样本采集方法,是多次采样的最佳方法。因此,我们旨在评估SR水平、客观多导睡眠图(PSG)参数和主观睡眠症状之间的相关性。方法前瞻性地纳入56名在我们诊所就诊超过1年的儿童;这些儿童接受了临床评估、问卷调查和PSG。SR在两个点进行测量:巴黎圣日尔曼足球俱乐部之前的晚上和巴黎圣日曼足球俱乐部之后的凌晨。结果56例受试者分为对照组(n=23,AHI<1)和OSAS组(n=33,AHI≥1)。OSAS组和对照组PSG后的SR水平同样高于PSG前。两组之间以及对照组和OSAS亚组之间的SR水平没有显著差异。OSAS亚组的SR水平与AHI、扁桃体大小、AN(腺样体-鼻咽)比率、问卷结果、最低血氧饱和度和氧去饱和指数(ODI)无关。结论saaSR水平与AHI、韩国版改良儿童Epworth嗜睡量表评分、最低血氧饱和度和ODI无显著相关性;无论OSAS的存在与否,SR水平都表现出昼夜变化。然而,对于抵抗素水平与OSAS之间的关系还没有达成共识。今后应进行进一步的研究。Sleep Med res 2018;9(2):77-82

Background and ObjectiveaaA nightmare is an unpleasant dream that awakes individuals and causes anxiety, fear and despair which lead to impulsive behaviors such as night eating. The purpose of this study is to investigate the mediating effects of depression and anxiety on the relationship between nightmare and night eating syndrome (NES). Both depression and anxiety are strongly relevant to a nightmare, which could increase night eating behaviors. MethodsaaParticipants of the study were 171 female undergraduate students (mean age 21.70 ± 1.76 years). All completed the following questionnaires: Disturbing Dream and Nightmare Severity Index, Night Eating Questionnaire, Hospital Anxiety and Depression Scale, and the Insomnia Severity Index. resultsaaResults showed there was a significant correlation among nightmare severity and night eating, depression, anxiety and insomnia (p < 0.05). After controlling for insomnia, anxiety continued to partially mediate the relationship between nightmare severity and NES (n = 171, B = 0.033, 95% CI = 0.001, 0.107). However, depression was not significant. ConclusionsaaIn conclusion, anxiety but not depression may be an important treatment target in treating females who have both nightmares and night eating.

背景和目的噩梦是一种令人不快的梦,它会唤醒个人,引起焦虑、恐惧和绝望,从而导致冲动行为,如夜间进食。本研究的目的是探讨抑郁和焦虑对噩梦与夜食综合征(NES)关系的中介作用。抑郁和焦虑都与噩梦密切相关,噩梦可能会增加夜间进食行为。方法研究对象为171名女大学生(平均年龄21.70±1.76岁)。所有人都完成了以下问卷调查:扰梦噩梦严重程度指数、夜间饮食问卷、医院焦虑抑郁量表和失眠严重程度指数。结果梦魇严重程度与夜食、抑郁、焦虑、失眠之间存在显著相关性(p<0.05)。控制失眠后,焦虑继续部分介导梦魇严重程度和NES之间的关系(n=171,B=0.033,95%CI=0.00010.107)。结论焦虑而非抑郁可能是治疗同时做噩梦和夜食的女性的重要治疗靶点。Sleep Med res 2018;9(2):104-109

Restless legs syndrome (RLS) is associated with dopaminergic dysfunction, and iron deficiency, manifesting as low ferritin. However, ferritin levels do not correlate well with demographic data. Based on the hypothesis that very low ferritin can accurately reflect clinical information, we herein described characteristics and treatment efficacy of RLS patients with ferritin levels under 15 ng/mL. We retrospectively reviewed 196 patients and collected clinical data. Twenty-one patients had ferritin levels under 15 ng/mL and were compared with those having ferritin levels over 15 ng/mL. The patients with very low ferritin levels were predominantly female, had earlier onset of symptoms, and showed a superior response to iron therapy. In conclusion, RLS patients with ferritin levels under 15 ng/mL showed distinct demographic features and treatment efficacy. Further studies on more patients with long-term follow-up are warranted to support this observation. Sleep Med Res 2018;9(2):118-123
