1氯吡格雷的使用与药物洗脱支架植入后远期临床结果显示文摘背景:近来的冠状动脉内药物洗脱支架研究提示,现行的抗血小板治疗方案可能并不足以预防后期支架内血栓形成。目的:于接受药物洗脱支架(drug-eluting stents,DESs)和裸金属支架(bare-metal stents,BMSs)治疗的冠状动脉病患者中评估氯吡格雷使用与患者远期结果的关系。设计、地点及患者:于连续患者中进行观察性研究。患者于2000年1月1日至2005年7月31日在杜克心脏治疗中心(一家位于北卡罗来纳州达累姆市的三级治疗中心)接受冠状动脉内支架治疗。于6、12、24个月时进行随访,直至2006年9月7日。研究人群包括4666例最初接受BMS(n=3165)或DES(n=1501)经皮冠状动脉介入治疗的患者。对随访6和12个月没有事件(没有死亡、心肌梗死或血管重建手术)的患者进行界标分析(landmark analysis)。在这些时间点上根据支架类型以及自我报告之氯吡格雷的使用情况将患者分为4组:DES使用氯吡格雷组、DES不用氯吡格雷组、BMS使用氯吡格雷组以及BMS不用氯吡格雷组。主要观测指标:随访24个月时死亡、非致命性心肌梗死以及死亡或心肌梗死之复合终点。结果:在6个月时没有事件发生的DES组患者(637例使用、579例未使用氯吡格雷)中,氯吡格雷的使用是随访24个月校正死亡率较低(使用2.0%比未使用5.3%;差异,-3.3%;95%CI,-6.3%至-0.3%;P=0.03)以及死亡或心肌梗死发生率较低(3.1%比7.2%;差异,-4.1%;95%CI,-7.6%至-0.6%;P=0.02)的显著预测指标。然而,在BMS组患者中(417例使用、1976例未用氯吡格雷),死亡(3.7%比4.5%;差异,-0.7%;95%CI,-2.9%至1.4%;P=0.50)以及死亡或心肌梗死发生率(5.5%比6.0%;差异,-0.5%;95%CI,-3.2%至2.2%;P:0.70)没有差异。在12个月随访没有事件发生的DES组患者(252例使用、276例未用氯吡格雷)中,氯吡格雷的使用依然可以预测24个月死亡(0%比3.5%;差异,-3.5%;95%CI,-5.9%至-1.1%;P=0.004)以及死亡或心肌梗死发生率(0%比4.5%;差异,-4.5%;95%CI,-7.1%至-1.9%;P〈0.001)较低。然而,在BMS组患者中(346例使用、1644例未用氯吡格雷),在死亡(3.3%比2.7%;差异,0.6%;95%CI,1.5%至2.8%;P=0.57)以及死亡或心肌梗死(4.7%比3.6%;差异,1.0%;95%CI,-1.6%至3.6%;P=0.44)发生方面,依然没有差异。结论:在接受DES治疗的患者中,延长氯吡格雷的使用可以使死亡以及死亡或心肌梗死的发生率下降。然而,使用氯吡格雷的适宜期限只能通过大型临床随机试验确定。Eric L Eisenstein, DBA Kevin J.

11On the reliability of predictions on Covid-19 dynamics: A systematic and critical review of modelling techniques显示文摘Since the emergence of the novel 2019 coronavirus pandemic in December 2019(COVID-19),numerous modellers have used diverse techniques to assess the dynamics of transmission of the disease,predict its future course and determine the impact of different control measures.In this study,we conducted a global systematic literature review to summarize trends in the modelling techniques used for Covid-19 from January 1st,2020 to November 30th,2020.We further examined the accuracy and precision of predictions by comparing predicted and observed values for cumulative cases and deaths as well as uncertainties of these predictions.From an initial 4311 peer-reviewed articles and preprints found with our defined keywords,242 were fully analysed.Most studies were done on Asian(78.93%)and European(59.09%)countries.Most of them used compartmental models(namely SIR and SEIR)(46.1%)and statistical models(growth models and time series)(31.8%)while few used artificial intelligence(6.7%),Bayesian approach(4.7%),Network models(2.3%)and Agent-based models(1.3%).For the number of cumulative cases,the ratio of the predicted over the observed values and the ratio of the amplitude of confidence interval(CI)or credibility interval(CrI)of predictions and the central value were on average larger than 1 indicating cases of inaccurate and imprecise predictions,and large variation across predictions.There was no clear difference among models used for these two ratios.In 75%of predictions that provided CI or CrI,observed values fall within the 95%CI or CrI of the cumulative cases predicted.Only 3.7%of the studies predicted the cumulative number of deaths.For 70%of the predictions,the ratio of predicted over observed cumulative deaths was less or close to 1.Also,the Bayesian model made predictions closer to reality than classical statistical models,although these differences are only suggestive due to the small number of predictions within our dataset(9 in total).In addition,we found a significant negative correlation(rho=-0.56,p=0.021)between this ratio and the length(in days)of the period covered by the modelling,suggesting that the longer the period covered by the model the likely more accurate the estimates tend to be.Our findings suggest that while predictions made by the different models are useful to understand the pandemic course and guide policy-making,some were relatively accurate and precise while other not.Janyce Eunice Gnanvi KolawoléValère Salako Gaëtan Brezesky Kotanmi Romain GlèlèKakaïPhD 2021Infectious Disease Modelling2021,6,1:1
