Repurposing of parenterally administered active substances used to treat pain both systemically and locally

Pain is a constant in our lives. The efficacy of drug therapy administered by the parenteral route is often limited either by the physicochemical characteristics of the drug itself or its adsorption–distribution–metabolism–excretion (ADME) mechanisms. One promising alternative is the design of innovative drug delivery systems that can improve the pharmacokinetics |(PK) and/or reduce the toxicity of traditionally used drugs. In this review, we discuss several products that have been approved by the main regulatory agencies (i.e., nano- and microsystems, implants, and oil-based solutions), highlighting the newest technologies that govern both locally and systemically the delivery of drugs. Finally, we also discuss the risk assessment of the scale-up process required, given the impact that this approach could have on drug manufacturing.Teaser: The management of pain by way of the parenteral route can be improved using complex drug delivery systems (e.g., micro- and nanosystems) which require high-level assessment and shorten the regulatory pathway.     

EEG functional connectivity contributes to outcome prediction of postanoxic coma

ObjectiveTo investigate the additional value of EEG functional connectivity features, in addition to non-coupling EEG features, for outcome prediction of comatose patients after cardiac arrest.MethodsProspective, multicenter cohort study. Coherence, phase locking value, and mutual information were calculated in 19-channel EEGs at 12 h, 24 h and 48 h after cardiac arrest. Three sets of machine learning classification models were trained and validated with functional connectivity, EEG non-coupling features, and a combination of these. Neurological outcome was assessed at six months and categorized as “good” (Cerebral Performance Category [CPC] 1–2) or “poor” (CPC 3–5).ResultsWe included 594 patients (46% good outcome). A sensitivity of 51% (95% CI: 34–56%) at 100% specificity in predicting poor outcome was achieved by the best functional connectivity-based classifier at 12 h after cardiac arrest, while the best non-coupling-based model reached a sensitivity of 32% (0–54%) at 100% specificity using data at 12 h and 48 h. Combination of both sets of features achieved a sensitivity of 73% (50–77%) at 100% specificity.ConclusionFunctional connectivity measures improve EEG based prediction models for poor outcome of postanoxic coma.SignificanceFunctional connectivity features derived from early EEG hold potential to improve outcome prediction of coma after cardiac arrest.     

目标教学在手术室护理带教中的应用效果观察

目的观察目标教学在手术室护理带教中的应用效果。方法选取2018年9月—2019年6月期间,医院手术室的48名实习护士,随机分为对照组和试验组,每组各24例。对照组行传统护理带教方法,试验组行目标教学带教。对比带教后两组考核成绩及带教满意度。结果带教后,试验组职业防护意识、风险意识、无菌观念、常见小中手术配合熟练度、常见小中手术护理要点掌握、基本工作职责及流程掌握等评分与对照组差异具有统计学意义(P<0.05)。试验组专科操作、操作测评及理论测评成绩与对照组差异具有统计学意义(P<0.05)。结论于手术室护理带教中应用目标教学,具有理想效果,有助于提升考核成绩及专业技能。     

EZH2对弥漫大B细胞淋巴瘤RCHOP方案治疗效果的预测价值

目的:探讨Zeste基因增强子(enhancer of zeste homolog 2,EZH2)对弥漫大B细胞淋巴瘤(diffuse large B-cell lymphoma,DLBCL)RCHOP方案治疗的效果的预测价值。方法:纳入2017年1月至2018年5月南华大学附属第二医院80例接受RCHOP方案治疗的DLBCL患者,分析患者EZH2表达情况与治疗效果的关系,绘制EZH2预测治疗效果的ROC曲线,并对患者pCR与病理特征的关系进行讨论。结果:80例患者中EZH2高表达者49例,EZH2低表达者31例,DLBCL患者RCHOP治疗的pCR率为51.25%,其中EZH2高表达患者完全缓解(complete response,CR)、客观缓解率(objective response rate,ORR)均明显低于EZH2低表达患者(P<0.05);EZH2预测治疗效果的曲线下面积为0.874(P<0.05);pCR与性别、年龄、美国东部肿瘤协作组(Eastern Cooperative Oncology Group,ECOG)得分、淋巴瘤国际预后指数(International Prognostic Index,IPI)得分、乳酸脱氢酶(lactate dehydrogenase,LDH)因素无相关关系(P>0.05);与Hans分型、EZH2表达水平存在一定的相关性(P<0.05)。结论:DLBCL患者EZH2低表达是RCHOP治疗后高pCR率的预测因子,在临床上有助于为DLBCL患者临床治疗提供更好的指导。
