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.

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.","PeriodicalId":37318,"journal":{"name":"Sleep Medicine Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45440530","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

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.

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.
