摘要:目的带状疱疹后神经痛(postherpetic neuralgia,PHN)是中国老年带状疱疹患者的一种严重而痛苦的并发症。PHN与高交感神经活动有关,目前通过脊髓电刺激(spinal cord stimulation,SCS)置入可有效缓解PHN。近年来,心率变异性(heart rate variability, HRV)分析作为自主神经系统(autonomic nervous system, ANS)可靠、客观的反馈指标被广泛应用于慢性疼痛。很少有研究报道ANS在SCS引起的疼痛缓解机制。因此,此研究旨在探讨SCS置入对PHN患者HRV的临床影响及其与疼痛结局的相关性。方法本研究为一项回顾性研究:选取2023年11月至2024年3月在中南大学湘雅三医院疼痛病房符合纳入标准的患者28例。每位患者均接受SCS置入治疗,获取SCS置入前后HRV数据,包括:连续24h所有正常至正常(心搏)间隔的标准偏差(standard deviation of normal-to-normal intervals,SDNN);差值均方的平方根(root mean square of successive differences,RMSSD);差值的标准差(standard deviation of successive differences,SDSD);相邻R-R间期差值>50ms的个数所占百分比(percentage of adjacent normal-to-normal intervals that differ by more than 50 milliseconds,PNN50);低频范围内的功率(low frequency,LF);高频范围内的功率(high frequency,HF); LF和HF比值(LF/HF); 5 min 内所有频率总功率(total power,TP)。结果SCS置入后,SDNN、RMSSD、SDSD、PNN50明显降低,LF、HF、TP略有降低。经SCS治疗后,LF/HF值无变化。SCS治疗对疼痛缓解、负面情绪改善、精神压力下降均有积极作用。同时,T8以上置入SCS对SDNN、LF、HF明显升高。同时计算了SCS治疗前后HRV参数的相关性。结论证实了PHN患者疼痛结局与自主神经活动存在同步变化,SCS置入改善了PHN患者的HRV稳定性,有利于心脏节律。此外,引入了HRV测量作为PHN患者ANS活动的证据。
“Reporting on a groundbreaking study, a 40-year-old man diagnosed with bilateral atypical optic neuritis experienced persistent visual acuity loss. Despite initial tests indicating syphilis, further examinations, including mitochondrial gene testing, revealed Leber hereditary optic neuropathy (LHON). This case underscores the importance of comprehensive etiological examinations, particularly gene testing, for early diagnosis and treatment in young male patients presenting with acute visual acuity loss and bilateral eye involvement.”
“In the field of women's health, a study has translated the German Pelvic Floor Questionnaire for Pregnant and Postpartum Women into Chinese and verified its reliability and validity. The Chinese version of the questionnaire has four dimensions and 45 entries, with good reliability, providing solutions to assess pelvic floor disorders and underlying risk factors during pregnancy and postpartum period.”
“In the field of osteosarcoma research, a team of experts has established a prognostic model based on anoikis-related genes and the tumor microenvironment. This model offers new insights into the treatment of osteosarcoma and is expected to provide clinicians with suitable therapeutic approaches.”
摘要:目的了解急诊科医务人员的职业倦怠现状,分析其影响因素,为预防急诊科医务人员职业倦怠提供参考。方法采取便利抽样的方法,通过问卷星平台,于2022年12月-2023年1月对急诊科医务人员进行横断面调查。采用职业倦怠量表(Maslach Burnout Inventory General Survey,MBI-GS)来评价医务人员的职业倦怠水平,采用单因素分析及二元logistic回归分析探索急诊科医务人员发生职业倦怠的影响因素。结果回收有效问卷1173份。其中职业倦怠者:946人(81%),轻中度和重度职业倦怠的比例分别为74%和7%。急诊医务人员职业倦怠三维度得分:情感耗竭(Emotional Exhaustion,EE)均分为2.33±0.31;去人格化(Depersonalization,DP)均分为1.88±0.28;低个人成就感(Low Personal Accomplishment,LPA)均分为3.20±0.39;总均分为2.46±0.22。急诊医务人员职业倦怠与是否独生子女、平均晚夜班数量(月)、工作中亲身经历过职场暴力事件有关。结论急诊科医务人员职业倦怠发生率高,管理者需采取有效的措施及时干预,以降低急诊医务人员的职业倦怠,保障急诊医务工作的顺利开展。
