Objective

To assay peripheral inter-ictal cytokine serum levels and possible relations with non-invasive vagus nerve stimulation (nVNS) responsiveness in migraineurs.

Methods

This double-blinded, sham-controlled study enrolled 48 subjects and measured headache severity, frequency [headache days/month, number of total and mild/moderate/severe classified attacks/month], functional state [sleep, mood, body weight, migraine-associated disability] and serum levels of inflammatory markers [inter-ictal] using enzyme-linked immunoassays at baseline and after 2 months of adjunctive nVNS compared to sham stimulation and suitably matched controls.

Results

No significant differences were observed at baseline and after 2 months for headache severity, total attacks/month, headache days/month and functional outcome [sleep, mood, disability] between verum and sham nVNS. However, the number of severe attacks/month significantly decreased in the verum nVNS group and circulating pro-inflammatory IL-1β was elevated significantly in the sham group compared to nVNS. Levels of anti-inflammatory IL-10 were significantly higher at baseline in both groups compared to healthy controls, but not at 2 months follow-up [p?<?0.05]. Concentrations of high-mobility group box-1 (HMGB-1), IL-6, tumor-necrosis factor-α (TNF-α), leptin, adiponectin, ghrelin remained unchanged [p?>?0.05]. No severe device-/stimulation-related adverse events occurred.

Conclusion

2 months of adjunctive cervical nVNS significantly declined the number of severe attacks/month. Pro-inflammatory IL-1β plasma levels [inter-ictal] were higher in sham-treated migraine patients compared to verum nVNS. However, pro- [IL-6, HMGB-1, TNF-α, leptin] and anti-inflammatory [IL-10, adiponectin, ghrelin] mediators did not differ statistically. Profiling of neuroinflammatory circuits in migraine to predict nVNS responsiveness remains an experimental approach, which may be biased by pre-analytic variables warranting large-scale biobank-based systematic investigations [omics].  相似文献

Most literature on the relationship between video gaming and sleep disturbances has looked at children and adolescents. There is little research on such a relationship in adult samples. The aim of the current study was to investigate the association of video game volume with sleep quality in adults via face‐to‐face interviews using standardized questionnaires. Adults (n = 844, 56.2% women), aged 18–94 years old, participated in the study. Sleep quality was measured using the Pittsburgh Sleep Quality Index, and gaming volume was assessed by asking the hours of gaming on a regular weekday (Mon–Thurs), Friday and weekend day (Sat–Sun). Adjusting for gender, age, educational level, exercise and perceived stress, results of hierarchical regression analyses indicated that video gaming volume was a significant predictor of sleep quality (β = 0.145), fatigue (β = 0.109), insomnia (β = 0.120), bedtime (β = 0.100) and rise time (β = 0.168). Each additional hour of video gaming per day delayed bedtime by 6.9 min (95% confidence interval 2.0–11.9 min) and rise time by 13.8 min (95% confidence interval 7.8–19.7 min). Attributable risk for having poor sleep quality (Pittsburgh Sleep Quality Index > 5) due to gaming >1 h day was 30%. When examining the components of the Pittsburgh Sleep Quality Index using multinomial regression analysis (odds ratios with 95% confidence intervals), gaming volume significantly predicted sleep latency, sleep efficiency and use of sleep medication. In general, findings support the conclusion that gaming volume is negatively related to the overall sleep quality of adults, which might be due to underlying mechanisms of screen exposure and arousal.  相似文献

目的 回顾1959年至2018年发表的灸法治疗失眠的临床文献,总结归纳灸法治疗失眠的临床应用规律。方法 检索《中国针灸信息库》、中国期刊全文数据库(清华同方)、万方数字化期刊(万方)、中文科技期刊全文数据库(维普),按照纳入和排除标准筛选灸法治疗失眠的临床研究文献,进行计量分析、聚类分析和关联性分析。结果 艾灸治疗失眠应用频次较高的穴位依次为百会、三阴交、神门、足三里;足太阳膀胱经穴应用频次最高,其次是督脉穴和肾经穴。下肢部的腧穴使用频次最高,其次为头面部、背部。关联性较高的穴对为内关、足三里、神门、百会和三阴交,关联性较高的治疗方法为艾条灸配合针刺。灸法配合中药的总有效率最高,其次为灸法配合针刺,疗效均优于单纯灸法(均P < 0.05)。对比灸法、灸药并用、灸刺并用疗法治疗前后的PSQI评分,灸法与灸药并用疗法比较差异有统计学意义(P < 0.05),与灸刺并用比较差异无统计学意义(P > 0.05)。结论 灸法治疗失眠的组方中主要穴对为内关、足三里、神门、百会和三阴交。配合疗法中灸刺结合的使用频率最高,但灸法配合中药疗法的有效率最高,对于PSQI评分的改善程度亦最大。  相似文献

BackgroundAllostatic load (AL) measures the cumulative impact of chronic stress and is associated with adverse health outcomes. A novel scoring system has previously been developed for AL in early pregnancy that is associated with pre-eclampsia. It was hypothesized that AL, as identified by the present model, is associated with psychosocial stressors and, specifically, poor sleep quality.MethodsWomen were selected from a low-risk, community-dwelling study population who enrolled at <15 weeks gestation. Nine physiologic components were divided among the domains of cardiovascular, metabolic, and inflammatory function. Spearman's rank correlations were used to examine the association of AL with age, income, the Revised Prenatal Distress Questionnaire (NuPDQ), Inventory of Depressive Symptoms (IDS), and Pittsburgh Sleep Quality Index (PSQI). The Wilcoxon rank-sum test was used to compare AL by race and educational attainment.ResultsA total of 103 women were identified, with: a mean age of 29.8 ± 5.0 years, 17.5% black, and mean gestational age 12.2 ± 1.1 weeks. Allostatic load was positively correlated with the PSQI (ρ = 0.23, p = 0.018). There were no associations with age, income, prenatal distress, race, or depression scores. College-educated women had lower AL compared with those with less education (0.57 ± 0.43 vs 0.81 ± 0.55, p = 0.045).ConclusionHigher AL, measured by the pregnancy-specific model, was associated with poorer sleep quality and lower educational attainment, both of which were considered to be chronic stressors. These relationships were consistent with previous findings in non-pregnant populations, and suggest that AL may be useful for capturing the physiologic impact of chronic stress in early pregnancy.  相似文献

 目的 研究药物联合正念减压治疗对广泛性焦虑障碍(generalized anxiety disorder,GAD)的效果。方法 收集2017-06至2019-05入院的GAD患者76例为研究对象,采用随机数字表法分为研究组和对照组,各38例,两组均给予常规精神科心理指导及系统药物治疗,研究组同时给予正念减压疗法,治疗时间2个月。比较治疗前后两组的焦虑自评量表(self-rating anxiety scale,SAS)[5]、汉密尔顿焦虑量表(hamilton anxiety scale,HAMA)[6],抑郁自评量表(self-rating depression scale,SDS)[7]、匹兹堡睡眠质量指数量表(pittsburgh sleep quality index,PSQI)得分。结果 两组患者治疗前SAS、SDS、HAMA总分均值比较,差异均无统计学意义;两组患者治疗后与治疗前比较,差异有统计学意义(P<0.05);研究组治疗后SAS、SDS、HAMA总分均值与对照组比较,明显下降,差异有统计学意义(t=3.14,P<0.05)。治疗后研究组PSQI各因子均值均低于对照组,差异有统计学意义(P<0.05)。结论 药物联合正念减压治疗比单纯药物治疗更能缓解GAD焦虑抑郁症状,改善睡眠水平,提高生活质量。  相似文献
