2Nationwide trends and predictors of inpatient mortality in 83884 transjugular intrahepatic portosystemic shunt显示文摘AIM: To evaluate and validate the national trends and predictors of in-patient mortality of transjugular intrahepatic portosystemic shunt(TIPS) in 15 years.METHODS: Using the National Inpatient Sample which is a part of Health Cost and Utilization Project, we identified a discharge-weighted national estimate of 83884 TIPS procedures performed in the United States from 1998 to 2012 using international classification of diseases-9 procedural code 39.1. The demographic, hospital and co-morbility data were analyzed using a multivariant analysis. Using multi-nominal logistic regression analysis, we determined predictive factors related to increases in-hospital mortality. Comorbidity measures are in accordance to the Comorbidity Software designed by the Agency for Healthcare Research and Quality.RESULTS: Overall, 12.3% of patients died during hospitalization with downward trend in-hospitalmortality with the mean length of stay of 10.8 ± 13.1 d. Notable, African American patients(OR = 1.809 vs Caucasian patients, P < 0.001), transferred patients(OR = 1.347 vs non-transferred, P < 0.001), emergency admissions(OR = 3.032 vs elective cases, P < 0.001), patients in the Northeast region(OR = 1.449 vs West, P < 0.001) had significantly higher odds of inhospital mortality. Number of diagnoses and number of procedures showed positive correlations with in-hospital death(OR = 1.249 per one increase in number of procedures). Patients diagnosed with acute respiratory failure(OR = 8.246), acute kidney failure(OR = 4.359), hepatic encephalopathy(OR = 2.217) and esophageal variceal bleeding(OR = 2.187) were at considerably higher odds of in-hospital death compared with ascites(OR = 0.136, P < 0.001). Comorbidity measures with the highest odds of in-hospital death were fluid and electrolyte disorders(OR = 2.823), coagulopathy(OR = 2.016), and lymphoma(OR = 1.842).CONCLUSION: The overall mortality of the TIPS procedure is steadily decreasing, though the length of stay has remained relatively constant. Specific patient ethnicity, location, transfer status, primary diagnosis and comorbidities correlate with increased odds of TIPS in-hospital death.Edward Wolfgang Lee Andrew Kuei Sammy Saab Ronald W Busuttil Francisco Durazo Steven-Huy Han Mohamed M El-Kabany Justin P Mc Williams Stephen T Kee 2016World Journal of Gastroenterology2016,22,25:7

5Randomised controlled trial comparing modified Sano's and narrow band imaging international colorectal endoscopic classifications for colorectal lesions显示文摘AIM To assess the utility of modified Sano′s(MS) vs thenarrow band imaging international colorectal endoscopic(NICE) classification in differentiating colorectal polyps.METHODS Patients undergoing colonoscopy between 2013 and 2015 were enrolled in this trial.Based on the MS or the NICE classifications,patients were randomised for real-time endoscopic diagnosis.This was followed by biopsies,endoscopic or surgical resection.The endoscopic diagnosis was then compared to the final(blinded) histopathology.The primary endpoint was the sensitivity(Sn),specificity(Sp),positive predictive value(PPV) and negative predictive value(NPV) of differentiating neoplastic and non-neoplastic polyps(MSⅡ/Ⅱo/Ⅲa/Ⅲb vs I or NICE 1 vs 2/3).The secondary endpoints were 'endoscopic resectability'(MSⅡ/Ⅱo/Ⅲa vs Ⅰ/Ⅲb or NICE 2 vs 1/3),NPV for diminutive distal adenomas and prediction of post-polypectomy surveillance intervals.RESULTS A total of 348 patients were evaluated.The Sn,Sp,PPV and NPV in differentiating neoplastic polyps from non-neoplastic polyps were,98.9%,85.7%,98.2% and 90.9% for MS;and 99.1%,57.7%,95.4% and 88.2% for NICE,respectively.The area under the receiver operating characteristic curve(AUC) for MS was 0.92(95%CI:0.86-0.98);and AUC for NICE was 0.78(95%CI:0.69,0.88).The Sn,Sp,PPV and NPV in predicting 'endoscopic resectability' were 98.9%,86.1%,97.8% and 92.5% for MS;and 98.6%,66.7%,94.7% and 88.9% for NICE,respectively.The AUC for MS was 0.92(95%CI:0.87-0.98);and the AUC for NICE was 0.83(95%CI:0.75-0.90).The AUC values were statistically different for both comparisons(P = 0.0165 and P = 0.0420,respectively).The accuracy for diagnosis of sessile serrated adenoma/polyp(SSA/P) with high confidence utilizing MS classification was 93.2%.The differentiation of SSA/P from other lesions achieved Sp,Sn,PPV and NPV of 87.2%,91.5%,89.6% and 98.6%,respectively.The NPV for predicting adenomas in diminutive rectosigmoid polyps(n = 150) was 96.6% and 95% with MS and NICE respectively.The calculated accuracy of post-polypectomy surveillance for MS group was 98.2%(167 out of 170) and for NICE group was 92.1%(139 out of 151).CONCLUSION The MS classification outperformed the NICE classification in differentiating neoplastic polyps and predicting endoscopic resectability.Both classifications met ASGE PIVI thresholds.Leonardo Zorrón Cheng Tao Pu Kuan Loong Cheong Doreen Siew Ching Koay Sze Pheh Yeap Amanda Ovenden Mahima Raju Andrew Ruszkiewicz Philip W Chiu James Y Lau Rajvinder Singh 2018World Journal of Gastrointestinal Endoscopy2018,10,9:4
6Chemokines,chemokine receptors and the gastrointestinal system显示文摘The biological properties of tumor cells are known to be regulated by a multitude of cytokines and growth factors,which include epidermal growth factor receptor agonists and members of the transforming growth factor β family.Furthermore,the recent explosion of research in the field of chemokine function as mediators of tumor progression has led to the possibility that these small,immunomodulatory proteins also play key roles in carcinogenesis and may,therefore,be potential targets for novel therapeutic approaches.In this review,we will summarize recently reported findings in chemokine biology with a focus on the gastrointestinal tract.Hiroshi Miyazaki Kazuaki Takabe W Andrew Yeudall 2013World Journal of Gastroenterology2013,19,19:4
7Scaffolds based therapy for osteochondral lesions of the talus:A systematic review显示文摘AIM To clarify the effectiveness of scaffold-based therapy for osteochondral lesions of the talus(OLT). METHODS A systematic search of MEDLINE and EMBASE databases was performed during August 2016 and updated in January 2017. Included studies were evaluated with regard to the level of evidence(LOE) and quality of evidence(QOE) using the Modified Coleman Methodology Score. Variable reporting outcome data, clinical outcomes, and the percentage of patients who returned to sport at previous level were also evaluated. RESULTS Twenty-eight studies for a total of 897 ankles were included; 96% were either LOE Ⅲ or Ⅳ. Studies were designated as either of poor or fair quality. There were 30 treatment groups reporting six different scaffold repair techniques: 13 matrix-induced autologous chondrocyte transplantation(MACT), nine bone marrow derived cell transplantation(BMDCT), four autologous matrixinduced chondrogeneis(AMIC), and four studies of other techniques. The categories of general demographics(93%) and patient-reported outcome data(85%) were well reported. Study design(73%), imaging data(73%), clinical variables(49%), and patient history(30%) were also included. The weighted mean American Orthopaedic Foot and Ankle Society(AOFAS) score at final follow-up was: 86.7 in MACT, 88.2 in BMDCT, and 82.3 in AMIC. Eight studies reported that a weighted mean of 68.3% ofpatients returned to a previous level of sport activity. CONCLUSION Scaffold-based therapy for OLT may produce favorable clinical outcomes, but low LOE, poor QOE, and variability of the data have confounded the effectiveness of this treatment.Yoshiharu Shimozono Youichi Yasui Andrew W Ross Wataru Miyamoto John G Kennedy 2017World Journal of Orthopedics2017,8,10:4
8生物素——抗结核药物新研究方向(英文)显示文摘耐药菌的出现对全球公共卫生构成了巨大的挑战,结核分枝杆菌(TB)是结核病的病原菌,是临床上最重要的病原体之一。新抗生素的研发用以治疗耐药性结核病已成为临床及公共卫生管理亟待解决的重要问题。生物素(维生素B7)在结核杆菌的代谢途径如脂肪酸合成和三羧酸循环中发挥重要作用,通过生物素蛋白连接酶连接活性辅助因子而被激活。生物素蛋白连接酶及其相关生物合成通路是微生物合成生物素过程中必不可或缺的关键分子,因而有可能成为新的药物靶点。遗传研究表明,结核杆菌需要由菌体进行生物素的全程合成,因此,生物素合成酶在在结核杆菌代谢过程中起着至关重要的作用,引起了抗结核药物研究者的高度重视。本文论述了结核杆菌生物素合成通路,并重点分析了生物素合成过程中可能成为药物靶点的关键酶,旨在为结核病的治疗提供新思路,具有重要的临床意义。THOMPSON Andrew P STERNICKI Louise M WEGENER Kate L 陆伟 竺丽梅 BOOKER Grant W POLYAK Steven W 李燕 2016江苏预防医学2016,27,3:4
9Gastric intestinal metaplasia is associated with gastric dysplasia but is inversely correlated with esophageal dysplasia显示文摘AIM To determine which clinical factors might be associated with gastric intestinal metaplasia(IM) in a North American population.METHODS Pathology and endoscopy databases at an academicmedical center were reviewed to identify patients with and without gastric IM on biopsies for a retrospective cohort study. Patient demographics, insurance status, and other clinical factors were reviewed.RESULTS Four hundred and sixty-eight patients with gastric IM(mean age: 61.0 years ± 14.4 years, 55.5% female) and 171 without gastric IM(mean age: 48.8 years ± 20.8 years, 55.0% female) were compared. The endoscopic appearance of atrophic gastritis correlated with finding gastric IM on histopathology(OR = 2.05, P = 0.051). Gastric IM was associated with histologic findings of chronic gastritis(OR = 2.56, P < 0.001), gastric ulcer(OR = 6.97, P = 0.015), gastric dysplasia(OR = 6.11, P = 0.038), and gastric cancer(OR = 6.53, P = 0.027). Histologic findings of Barrett's esophagus(OR = 0.28, P = 0.003) and esophageal dysplasia(OR = 0.11, P = 0.014) were inversely associated with gastric IM. Tobacco use(OR = 1.73, P = 0.005) was associated with gastric IM.CONCLUSION Patients who smoke or have the endoscopic finding of atrophic gastritis are more likely to have gastric IM and should have screening gastric biopsies during esophagogastroduodenoscopy(EGD). Patients with gastric IM are at increased risk for having gastric dysplasia and cancer, and surveillance EGD with gastric biopsies in these patients might be reasonable.Justin M Gomez James T Patrie Wissam Bleibel Jeanetta W Frye Bryan G Sauer Vanessa M Shami Edward B Stelow Christopher A Moskaluk Andrew Y Wang 2017World Journal of Gastrointestinal Endoscopy2017,9,2:3

12A new Early Cretaceous dinosaur track assemblage and the first definite non-avian theropod swim trackway from China显示文摘The trackway of a swimming theropod (ichnogenus Characichnos) is reported from the Lower Cretaceous Feitianshan Formation of Sichuan, China. These swim tracks help confirm that non-avian theropods were capable of forging moderately deep bodies of water. The trackway occurs on the same surface as a typical walking trackway of a sauropod (ichnogenus Brontopodus). Both occurrences are the first reported from the Cretaceous of Sichuan, and the swim tracks are the first well-preserved example of a Characichnos trackway from China. Additionally, a theropod walking trackway and several ornithopod walking trackways (similar to the ichnogenus Caririchnium) occur in the same horizon. The ornithopod trackways show a parallel orientation, suggesting gregarious behavior of the trackmakers, which may have been iguanodontiforms and/or hadrosauriforms. The co-occurrence of theropod swim tracks and theropod walking tracks suggests a fluctuation of water depth within a distinct time span.XING LiDa LOCKLEY Martin G ZHANG JianPing MILNER Andrew R C KLEIN Hendrik LI DaQing PERSONS IV W Scott EBI JieFang 2013Chinese Science Bulletin2013,58,19:3
