This longitudinal observational study used data from actively deployed troops to correlate third-person observer ratings of deployment peritraumatic behaviors [Peritraumatic Behavior Questionnaire- Observer Rated(PBQ-OR)] collected on a bimonthly basis with post-deployment(1-wk follow-up) ratings of the previously validated PBQ self-rate version(PBQ-SR), and(3-mo follow-up) clinician assessed and self-report posttraumatic stress disorder(PTSD) symptoms(Clinician Administered PTSD Scale, PTSD Checklist). Cronbach's alpha(α) and correlation coefficients were calculated to assess internal reliability and concurrent validity respectively. RESULTS: Eight hundred and sixty male Marines were included in this study after signing informed consents at pre-deployment(mean age 23.2 ± 2.6 years). Although our findings were limited by an overall sparse return rate of PBQ-OR ratings, the main results indicate satisfactory psychometric properties with good internal consistency for the PBQ-OR(α = 0.88) and high convergent and concurrent validity with 1-wk post-deployment PBQSR ratings and 3-mo posttraumatic stress symptoms. Overall, later PBQ-OR report date was associated with higher correlation between PBQ-OR and postdeployment measures. Kappa analysis between PBQOR and PBQ-SR single items, showed best agreement in questions relating of mortal peril, desire for revenge, and experience of intense physical reactions. Logistic regression demonstrated satisfactory predictive validity of PBQ-OR total score with respect to PTSD caseness(OR = 1.0513; 95%CI: 1.011-1.093; P = 0.02).CONCLUSION: Since no comparable tools have been developed, PBQ-OR could be valuable as real-time screening tool for earlier detection of Service Members at risk.展开更多

It is described as an enhanced version of the current definition of PTSD, with clinical features of PTSD plus three additional clusters of symptoms namely emotional dysregulation, negative self-cognitions and interpersonal hardship, thus resembling the clinical features commonly encountered in borderline personality disorder(BPD). Complex PTSD is related to complex trauma which is defined by its threatening and entrapping context, generally interpersonal in nature. In this manuscript, we review the current findings related to traumatic events predisposing the above-mentioned disorders as well as the biological correlates surrounding them, along with their clinical features. Furthermore, we suggest that besides the present distinct clinical diagnoses(PTSD; Complex PTSD; BPD), there is a cluster of these comorbid disorders, that follow a continuum of trauma and biological severity on a spectrum of common or similar clinical features and should be treated as such. More studies are needed to confirm or reject this hypothesis, particularly in clinical terms and how they correlate to clinical entities' biological background, endorsing a shift from the phenomenologically only classification of psychiatric disorders towards a more biologically validated classification.展开更多

文摘目的探讨胎盘间充质干细胞(P-MSCs)对胰腺创伤(PT)大鼠的保护作用。方法健康成年雄性SD大鼠60只,随机分为对照组、胰腺创伤组(胰腺损伤区域及创伤周围局部注射1 ml PBS溶液)与P-MSCs组[胰腺损伤区域及创伤周围局部注射1 ml P-MSCs(1×106个/ml)],每组20只。采用400 kPa的致伤压强建立胰腺创伤大鼠模型。于术后1、3、5、7 d每组处死5只大鼠,收集血清及胰腺组织。HE染色观察胰腺组织病理学变化并进行病理损伤评分,ELISA法测定血清中淀粉酶(AMS)、脂肪酶(LPS)、肿瘤坏死因子-α(TNF-α)、白细胞介素-6(IL-6)、IL-10、转化生长因子-β1(TGF-β1)浓度,以及胰腺组织中髓过氧化物酶(MPO)、超氧化物歧化酶(SOD)活性,TUNEL法观察胰腺组织细胞凋亡情况。结果与对照组比较,胰腺创伤组与P-MSCs组在胰腺创伤发生后腹腔积液量增加(P<0.05),胰腺/体重比、胰腺组织病理损伤总评分均升高(P<0.05),血清AMS、LPS、TNF-α、IL-6浓度及MPO活性早期升高,随时间延长呈下降趋势(P<0.05),而抗炎因子IL-10浓度及SOD活性随时间延长呈上升趋势(P<0.01),TGF-β1浓度早期下降,随时间延长呈上升趋势(P<0.01),凋亡指数(AI)明显升高(P<0.001)。与胰腺创伤组比较,P-MSCs组大鼠胰腺组织大体形态得以改善,腹腔积液量减少(P<0.001),胰腺/体重比、胰腺组织病理损伤总评分降低(P<0.05),血清AMS、LPS、IL-6、TNF-α浓度及MPO活性更快恢复至正常水平(P<0.05),而抗炎因子IL-10、TGF-β1浓度及SOD活性升高速度增加(P<0.05),AI升高(P<0.001)。结论P-MSCs可促进PT大鼠组织修复,减轻其局部及全身炎症,改善组织氧化应激反应,促进胰腺腺泡细胞凋亡,对PT大鼠具有保护作用。
文摘目的探究创伤重症监护室(trauma intensive care unit,TICU)患者环境压力源感知程度及其影响因素对谵妄进展的影响。方法采用抽样法选取2022年6月—2023年6月于山东大学齐鲁医院TICU的395例患者为研究对象,采用一般资料调查表、ICU环境压力源量表(intensive care unit environmental stressor scale,ICUESS)进行调查分析患者环境压力源感知程度及其影响因素,采用多元线性回归分析TICU患者环境压力源感对谵妄进展的影响。结果创伤患者入住TICU期间影响压力感受程度最大的因素分别为疼痛、思念家人,环境压力源总分为(91.48±28.80)分,其中人文环境维度得分最高为(24.03±7.39)分,物理环境维度得分最低(21.82±7.25)分。多元线性回归分析显示,疼痛程度(>3分)、监护时间(>3 d)、肢体约束(是)、镇静(是)、焦虑总分是TICU患者环境压力感受程度的影响因素(P<0.05)。有98例患者发生亚谵妄,89例发生谵妄,发生率分别为24.8%、22.5%,发生亚谵妄患者环境压力源感知程度介于无谵妄与完全谵妄之间。结论TICU患者感受到的环境压力源感知程度处于较高的水平,疼痛程度较大、监护时间长、采取约束措施、镇静措施、焦虑程度较大的患者环境境压力源感知程度越重。监护室环境压力源感知程度越重的患者更易发生亚谵妄和谵妄,发生谵妄患者的压力源感知程度高于亚谵妄患者。护理人员应针对影响因素采取精准的干预措施,降低TICU患者对环境压力源的感知程度,减少患者亚谵妄及谵妄的发生,改善患者预后。
