| 1 | Artificial intelligence in gastroenterology: A state-of-the-art review显示文摘The development of artificial intelligence(AI)has increased dramatically in the last 20 years,with clinical applications progressively being explored for most of the medical specialties.The field of gastroenterology and hepatology,substantially reliant on vast amounts of imaging studies,is not an exception.The clinical applications of AI systems in this field include the identification of premalignant or malignant lesions(e.g.,identification of dysplasia or esophageal adenocarcinoma in Barrett’s esophagus,pancreatic malignancies),detection of lesions(e.g.,polyp identification and classification,small-bowel bleeding lesion on capsule endoscopy,pancreatic cystic lesions),development of objective scoring systems for risk stratification,predicting disease prognosis or treatment response[e.g.,determining survival in patients post-resection of hepatocellular carcinoma),determining which patients with inflammatory bowel disease(IBD)will benefit from biologic therapy],or evaluation of metrics such as bowel preparation score or quality of endoscopic examination.The objective of this comprehensive review is to analyze the available AI-related studies pertaining to the entirety of the gastrointestinal tract,including the upper,middle and lower tracts;IBD;the hepatobiliary system;and the pancreas,discussing the findings and clinical applications,as well as outlining the current limitations and future directions in this field. | Paul T Kröner Megan ML Engels Benjamin S Glicksberg Kipp W Johnson Obaie Mzaik Jeanin E van Hooft Michael B Wallace Hashem B El-Serag Chayakrit Krittanawong | 2021 | World Journal of Gastroenterology2021，27，40： | 6 |
| 2 | 一种房颤风险评分系统的建立(Framingham心脏研究):基于社区的队列研究显示文摘背景房颤导致了发病率和病死率的显著上升。本研究旨在建立一种预测个体罹患房颤绝对风险的风险评分系统,并提供研究人员评价新危险因素的流程。方法作者评估了Framingham心脏研究中于1968年6月至1987年9月间进行了8044次检测的4764例参与者(55%为女性,年龄45~95岁)。此后,参与者被随访至房颤首发,随访期最长达10年。多变量Coxi回归确认出1(1年内罹患房颤的临床危险因素。次级分析纳入了常规超声心动图检测指标(5152例4参与者,7156次检测)对房颤风险进行再分层评估,并评价超声检测指标能否提高风险预测能力。结果4764例参与者中的457例4(10%)罹患房颤。年龄、性别、体重指数、收缩压、降压治疗、PR间期、有临床意义的心脏杂音及心力衰竭与房颤相关,并被纳入了风险评分模型(除体重指数P=0.08外,其余均为P〈0.05),模型的C统计量为0.78(95%CI0.76~0.80)。10年房颤风险随年龄变化:年龄〈65岁的人群中53例(1%)风险高于15%,而〉65岁的人群中为783例(27%)。为提高预测能力而纳入超声检测指标仅使模型C统计量略微增高,由0.78(95%C10.75~0.80)增至0.79(95%CI0.77~0.82:P=0.005)。超声心动图检测指标并不能改善风险再分层评估(P=0.18)。结论基于社区医疗中易得的临床因素建立的风险评分系统,有助于确认社区个体罹患房颤的风险,评估技术或标志物能否改善风险预测,以及针对高危个体采取预防措施。 | Renate B Schnabel Lisa M Sullivan Daniel Levy Michael J Pencina Joseph M Massaro Ralph B D'Agostino Sr Christopher Newton-Cheh Jennifer F Yamamoto Jared W Magnani Thomas M Tadros William B Kannel Thomas J Wang Patrick T Ellinor Philip A Wolf Ramachanclran S Vasan Emelia J Benjamin 黄刚(译) | 2009 | 世界临床医学2009，，9： | 2 |
| 3 | Endothelin-1 activation in pediatric patients undergoing surgical coarctation of the aorta repair显示文摘AIM To determine endothelin-1(ET-1)concentration before and after surgical coarctectomy and evaluate its association with left ventricular geometric change.METHODSA prospective,cohort study of 24 patients aged 2 d to 10years with coarctation of the aorta undergoing surgical repair.A sub-cohort of patients with age<1 mo was classified as'neonates'.Echocardiograms were performed just prior to surgery and in the immediate post-op period to assess left ventricle mass index and relative wall thickness(RWT).Plasma ET-1 levels were assessed at both time points.Association between ET-1 levels and ventricular remodeling was assessed.RESULTSPatients<1 year demonstrated higher pre-op ET-1 than post-op(2.8 pg/m L vs 1.9 pg/m L,P=0.02).Conversely,patients>1 year had no change in ET-1 concentration before and after surgery(1.1 vs 1.4,NS).Pre-op,patients<1 year demonstrated significantly higher ET-1 than older children(2.8 vs 1.1,P=0.001).Post-op there was no difference between the age groups(1.9 vs 1.4,NS).Neither RWT nor left ventricle mass index(LVMI)varied from pre-op to post-op.The subset of neonates showed a strong positive correlation between pre-op ET-1 and RWT(r=0.92,P=0.001).Patients with ET-1>2 pg/m L preop demonstrated higher LVMI(65.7 g/m^(2.7) vs 38.5 g/m^(2.7),P=0.004)and a trend towards higher RWT(45%vs39%,P=0.07)prior to repair than those with lower ET-1concentration.CONCLUSIONET-1 concentration is significantly variable in the perioperative period surrounding coarctectomy.Older children and infants have different responses to surgical repair suggesting different mechanisms of activation. | Benjamin Steven Frank Tracy T Urban Suhong Tong Courtney Cassidy Max B Mitchell Christopher S Nichols Jesse A Davidson | 2017 | World Journal of Cardiology2017，9，12： | 2 |
