| 1 | Sequential organ failure assessment score is superior to other prognostic indices in acute pancreatitis显示文摘BACKGROUND Acute pancreatitis(AP)is a common surgical condition,with severe AP(SAP)potentially lethal.Many prognostic indices,including;acute physiology and chronic health evaluation II score(APACHE II),bedside index of severity in acute pancreatitis(BISAP),Glasgow score,harmless acute pancreatitis score(HAPS),Ranson’s score,and sequential organ failure assessment(SOFA)evaluate AP severity and predict mortality.AIM To evaluate these indices'utility in predicting severity,intensive care unit(ICU)admission,and mortality.METHODS A retrospective analysis of 653 patients with AP from July 2009 to September 2016 was performed.The demographic,clinical profile,and patient outcomes were collected.SAP was defined as per the revised Atlanta classification.Values for APACHE II score,BISAP,HAPS,and SOFA within 24 h of admission were retrospectively obtained based on laboratory results and patient evaluation recorded on a secure hospital-based online electronic platform.Data with<10%missing data was imputed via mean substitution.Other patient information such as demographics,disease etiology,and patient outcomes were also derived from electronic medical records.RESULTS The mean age was 58.7±17.5 years,with 58.7%males.Gallstones(n=404,61.9%),alcohol(n=38,5.8%),and hypertriglyceridemia(n=19,2.9%)were more common aetiologies.81(12.4%)patients developed SAP,20(3.1%)required ICU admission,and 12(1.8%)deaths were attributed to SAP.Ranson’s score and APACHE-II demonstrated the highest sensitivity in predicting SAP(92.6%,80.2%respectively),ICU admission(100%),and mortality(100%).While SOFA and BISAP demonstrated lowest sensitivity in predicting SAP(13.6%,24.7%respectively),ICU admission(40.0%,25.0%respectively)and mortality(50.0%,25.5%respectively).However,SOFA demonstrated the highest specificity in predicting SAP(99.7%),ICU admission(99.2%),and mortality(98.9%).SOFA demonstrated the highest positive predictive value,positive likelihood ratio,diagnostic odds ratio,and overall accuracy in predicting SAP,ICU admission,and mortality.SOFA and Ranson’s score demonstrated the highest area under receiver-operator curves at 48 h in predicting SAP(0.966,0.857 respectively),ICU admission(0.943,0.946 respectively),and mortality(0.968,0.917 respectively).CONCLUSION The SOFA and 48-h Ranson’s scores accurately predict severity,ICU admission,and mortality in AP,with more favorable statistics for the SOFA score. | Thomas Zheng Jie Teng Jun Kiat Thaddaeus Tan Samantha Baey Sivaraj K Gunasekaran Sameer P Junnarkar Jee Keem Low Cheong Wei Terence Huey Vishal G Shelat | 2021 | World Journal of Critical Care Medicine2021，10，6： | 9 |
| 2 | Reliability of ultrasound ovarian-adnexal reporting and data system amongst less experienced readers before and after training显示文摘BACKGROUND The 2018 ovarian-adnexal reporting and data system(O-RADS)guidelines are aimed at providing a system for consistent reports and risk stratification for ovarian lesions found on ultrasound.It provides key characteristics and findings for lesions,a lexicon of descriptors to communicate findings,and risk characterization and associated follow-up recommendation guidelines.However,the ORADS guidelines have not been validated in North American institutions or amongst less experienced readers.AIM To evaluate the diagnostic accuracy and inter-reader reliability of ultrasound ORADS risk stratification amongst less experienced readers in a North American institution with and without pre-test training.METHODS A single-center retrospective study was performed using 100 ovarian/adnexal lesions of varying O-RADS scores.Of these cases,50 were allotted to a training cohort and 50 to a testing cohort via a non-randomized group selection process in order to approximately equal distribution of O-RADS categories both within and between groups.Reference standard O-RADS scores were established through consensus of three fellowship-trained body imaging radiologists.Three PGY-4 residents were independently evaluated for diagnostic accuracy and inter-reader reliability with and without pre-test O-RADS training.Sensitivity,specificity,positive predictive value,negative predictive value(NPV),and area under the curve(AUC)were used to measure accuracy.Fleiss kappa and weighted quadratic(pairwise)kappa values were used to measure inter-reader reliability.Statistical significance was P<0.05.RESULTS Mean patient age was 40±16 years with lesions ranging from 1.2 to 22.5 cm.Readers demonstrated excellent specificities(85%-100%pre-training and 91%-100%post-training)and NPVs(89%-100%pre-training and 91-100%post-training)across the O-RADS categories.Sensitivities were variable(55%-100%pre-training and 64%-100%post-training)with malignant ORADS 4 and 5 Lesions pre-training and post-training AUC values of 0.87-0.95 and 0.94-098,respectively(P<0.001).Nineteen of 22(86%)misclassified cases in pre-training were related to mischaracterization of dermoid features or wall/septation morphology.Fifteen of 17(88%)of posttraining misclassified cases were related to one of these two errors.Fleiss kappa inter-reader reliability was‘good’and pairwise inter-reader reliability was‘very good’with pre-training and post-training assessment(k=0.76 and 0.77;and k=0.77-0.87 and 0.85-0.89,respectively).CONCLUSION Less experienced readers in North America achieved excellent specificities and AUC values with very good pairwise inter-reader reliability.They may be subject to misclassification of potentially malignant lesions,and specific training around dermoid features and smooth vs irregular inner wall/septation morphology may improve sensitivity. | Prayash Katlariwala Mitchell P Wilson Yeli Pi Baljot S Chahal Roger Croutze Deelan Patel Vimal Patel Gavin Low | 2022 | World Journal of Radiology2022，14，9： | 2 |
| 3 | 胚胎巨噬细胞和小胶质细胞消融调控小鼠胚胎背根神经节感觉神经元的发育显示文摘众所周知,小胶质细胞可以调节中枢神经系统发育的一些方面。在第11.5天的小鼠胚胎中的小胶质细胞定殖脊髓时,它们与背根神经节感觉神经元(SN)的生长中心轴突相互作用,这表明它们可能在SN发育中发挥一定功能。为了解决这个问题,我们使用缺乏胚胎巨噬细胞(PU.1敲除小鼠)和免疫细胞消融的小鼠胚胎分析胚胎巨噬细胞消融对SNs早期发育的影响。我们发现,除小胶质细胞外,胚胎巨噬细胞还与来自第11.5天的小鼠胚胎的原肌球蛋白受体激酶(Trk)C+感觉神经元,TrkB+感觉神经元和TrkA+感觉神经元外周神经突产生交联。免疫细胞剥夺会导致第11.5天的小鼠胚胎的TrkC+感觉神经元和TrkB+感觉神经元初始数量的减少,这与其发育细胞死亡(DCD)的改变有关联的可能性较小,因为其后在第12.5天的胚胎中的数量有短暂增加。在分析的发育期(第11.5~15.5天),它也导致TrkA+感觉神经元数量减少,尽管我们没有观察到他们的DCD有任何变化。与神经元祖细胞可能存在一致性的脑脂肪酸结合蛋白(BFABP-)阴性细胞的增殖在第11.5天的胚胎中增加,而它们的增殖在第12.5天的胚胎减少,这可部分解释从11.5 d观察到的SN亚型产生的改变。此外,我们观察到在缺乏胚胎巨噬细胞的情况下神经胶质细胞祖细胞(BFABP+细胞)增殖的改变。我们的数据表明,胚胎巨噬细胞和小胶质细胞消融调控SN的发育。 | Angelim MKSC Maia LMSS Mouffle C Ginhoux F Low D Amancio-Dos-Santos A Makhoul J Le Corronc H Mangin JM Legendre P 聂昊(编译) | 2018 | 神经损伤与功能重建2018，13，9： | 2 |
