1Colon cancer-associated B2 Escherichia coli colonize gut mucosa and promote cell proliferation显示文摘AIM:To provide further insight into the characterization of mucosa-associated Escherichia coli(E.coli)isolated from the colonic mucosa of cancer patients.METHODS:Phylogroups and the presence of cyclomodulin-encoding genes of mucosa-associated E.coli from colon cancer and diverticulosis specimens weredetermined by PCR.Adhesion and invasion experiments were performed with I-407 intestinal epithelial cells using gentamicin protection assay.Carcinoembryonic antigen-related cell adhesion molecule 6(CEACAM6)expression in T84 intestinal epithelial cells was measured by enzyme-linked immunosorbent assay and by Western Blot.Gut colonization,inflammation and procarcinogenic potential were assessed in a chronic infection model using CEABAC10 transgenic mice.Cell proliferation was analyzed by real-time mRNA quantification of PCNA and immunohistochemistry staining of Ki67.RESULTS:Analysis of mucosa-associated E.coli from colon cancer and diverticulosis specimens showed that whatever the origin of the E.coli strains,86%of cyclomodulin-positive E.coli belonged to B2 phylogroup and most harbored polyketide synthase(pks)island,which encodes colibactin,and/or cytotoxic necrotizing factor(cnf)genes.In vitro assays using I-407 intestinal epithelial cells revealed that mucosa-associated B2 E.coli strains were poorly adherent and invasive.However,mucosa-associated B2 E.coli similarly to Crohn’s disease-associated E.coli are able to induce CEACAM6expression in T84 intestinal epithelial cells.In addition,in vivo experiments using a chronic infection model of CEACAM6 expressing mice showed that B2 E.coli strain11G5 isolated from colon cancer is able to highly persist in the gut,and to induce colon inflammation,epithelial damages and cell proliferation.CONCLUSION:In conclusion,these data bring new insights into the ability of E.coli isolated from patients with colon cancer to establish persistent colonization,exacerbate inflammation and trigger carcinogenesis.Jennifer Raisch Emmanuel Buc Mathilde Bonnet Pierre Sauvanet Emilie Vazeille Amélie de Vallée Pierre Déchelotte Claude Darcha Denis Pezet Richard Bonnet Marie-Agnès Bringer Arlette Darfeuille-Michaud 2014World Journal of Gastroenterology2014,20,21:12
2Vanishing bile duct syndrome in human immunodeficiency virus infected adults:A report of two cases显示文摘Vanishing bile duct syndrome(VBDS) is a group of rare disorders characterized by ductopenia,the progressive destruction and disappearance of intrahepatic bile ducts leading to cholestasis.Described in association with medications,autoimmune disorders,cancer,transplantation,and infections,the specific mechanisms of disease are not known.To date,only 4 cases of VBDS have been reported in human immunodeficiency virus(HIV) infected patients.We report 2 additional cases of HIV-associated VBDS and review the features common to the HIV-associated cases.Presentation includes hyperbilirubinemia,normal liver imaging,and negative viral and autoimmune hepatitis studies.In HIV-infected subjects,VBDS occurred at a range of CD4+ T-cell counts,in some cases following initiation or change in antiretroviral therapy.Lymphoma was associated with two cases;nevirapine,antibiotics,and viral co-infection were suggested as etiologies in the other cases.In HIV-positive patients with progressive cholestasis,early identification of VBDS and referral for transplantation may improve outcomes.Ana Paula Oppenheimer Christopher Koh Mary McLaughlin John C Williamson Thomas D Norton Jennifer Laudadio Theo Heller David E Kleiner Kevin P High Caryn G Morse 2013World Journal of Gastroenterology2013,19,1:8

4Using quality improvement methods to increase use of pain prevention strategies for childhood vaccination显示文摘AIM To increase evidence-based pain prevention strategy use during routine vaccinations in a pediatric primary care clinic using quality improvement methodology.METHODS Specific intervention strategies(i.e.,comfort positioning,nonnutritive sucking and sucrose analgesia,distraction) were identified,selected and introduced in three waves,using a Plan-Do-Study-Act framework.System-wide change was measured from baseline to post-intervention by:(1) percent of vaccination visits during which an evidence-based pain prevention strategy was reported as being used; and(2) caregiver satisfaction ratings following the visit.Additionally,self-reported staff and caregiver attitudes and beliefs about pain prevention were measured at baseline and 1-year post-intervention to assess for possible long-term cultural shifts.RESULTS Significant improvements were noted post-intervention.Use of at least one pain prevention strategy was documented at 99% of patient visits and 94% of caregivers were satisfied or very satisfied with the pain prevention care received.Parents/caregivers reported greater satisfaction with the specific pain prevention strategy used [t(143) = 2.50,P ≤ 0.05],as well as greater agreement that the pain prevention strategies used helped their children's pain [t(180) = 2.17,P ≤ 0.05] and that they would be willing to use the same strategy again in the future [t(179) = 3.26,P ≤ 0.001] as compared to baseline.Staff and caregivers also demonstrated a shift in attitudes from baseline to 1-year post-intervention.Specifically,staff reported greater agreement that the pain felt from vaccinations can result in harmful effects [2.47 vs 3.10; t(70) =-2.11,P ≤ 0.05],less agreement that pain from vaccinations is 'just part of the process' [3.94 vs 3.23; t(70) = 2.61,P ≤ 0.05],and less agreement that parents expect their children to experience pain during vaccinations [4.81 vs 4.38; t(69) = 2.24,P ≤ 0.05].Parents/caregivers reported more favorable attitudes about pain prevention strategies for vaccinations across a variety of areas,including safety,cost,time,and effectiveness,as well as less concern about the pain their children experience with vaccination [4.08 vs 3.26; t(557) = 6.38,P ≤ 0.001],less need for additional pain prevention strategies [3.33 vs 2.81; t(476) = 4.51,P ≤ 0.001],and greater agreement that their doctors' office currently offers pain prevention for vaccinations [3.40 vs 3.75; t(433) =-2.39,P ≤ 0.05].CONCLUSION Quality improvement methodology can be used to help close the gap in implementing pain prevention strategies during routine vaccination procedures for children.Jennifer Verrill Schurman Amanda D Deacy Rebecca J Johnson Jolynn Parker Kristi Williams Dustin Wallace Mark Connelly Lynn Anson Kevin Mroczka 2017World Journal of Clinical Pediatrics2017,6,1:3
5一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

7Brugada phenocopy: A new electrocardiogram phenomenon显示文摘Brugada phenocopies(BrP) are clinical entities that are etiologically distinct from true congenital Brugada syndrome. BrP are characterized by type 1 or type 2 Brugada electrocardiogram(ECG) patterns in precordial leads V1-V3. However, BrP are elicited by various un-derlying clinical conditions such as myocardial ischemia, pulmonary embolism, electrolyte abnormalities, or poor ECG filters. Upon resolution of the inciting underlying pathological condition, the BrP ECG subsequently nor-malizes. To date, reports have documented BrP in the context of singular clinical events. More recently, recur-rent BrP has been demonstrated in the context of re-current hypokalemia. This demonstrates clinical repro-ducibility, thereby advancing the concept of this new ECG phenomenon. The key to further understanding the pathophysiological mechanisms behind BrP requires experimental model validation in which these phenom-ena are reproduced under strictly controlled environ-mental conditions. The development of these validation models will help us determine whether BrP are tran-sient alterations of sodium channels that are not repro-ducible with a sodium channel provocative test or al-ternatively, a malfunction of other ion channels. In this editorial, we discuss the conceptual emergence of BrP as a new ECG phenomenon, review the progress made to date and identify opportunities for further investiga-tion. In addition, we also encourage investigators that are currently reporting on these cases to use the term BrP in order to facilitate literature searches and to help establish this emerging concept.Daniel D Anselm Jennifer M Evans Adrian Baranchuk 2014World Journal of Cardiology2014,6,3:2

9胸腹主动脉瘤:杂交修复术结果显示文摘目的:胸腹主动脉瘤(TAAA)的治疗依然是外科中最富挑战性的工作,特别是存在退行性变动脉瘤的老年患者同时患肺疾病更是如此。这篇更新后的单中心报道是关于我们对高危TAAA患者采用完全内脏动脉去分支化结合动脉瘤腔内隔绝的杂交修复术经验。方法:从2005年3月—2012年6月间58名患者在单中心接受解剖外内脏血管去分支化及随后的动脉瘤腔内隔绝术。内脏旁路的中位数为4支,最初的33例采用同期手术方式,而最近的25例采用分期手术。结果:患者中位年龄为69.0岁,50%为女性,所有患者存在严重合并症而不适合传统开放修复术。平均主动脉直径(6.7±1.2)cm,30 d/住院病死率、脑卒中率、永久性轻瘫/截瘫率分别为9%、0%以及4%。最近25例分期手术患者的这三种并发症率分别为4%、0%以及0%。平均随访时间(26±21)个月,内脏人工血管通畅率95.3%,所有闭塞的内脏人工血管均为肾动脉,无1例引起永久性截瘫,2例患者需再干预,1例出现Ib型内漏,1例出现III型内漏,5年免于再干预率为94%,Kaplan-Meier总体生存率为1年78%、5年62%,5年主动脉相关生存率为87%。结论:这些更新后的结果 ,继续支撑着这一观点:运用完全内脏动脉去分支联合动脉瘤腔内隔绝的杂交技术治疗高龄且不适合传统开放手术的高危TAAA患者是一种理想的选择,而采取分期手术的方式能取得更佳的结果。Gchad Hughes Nicholas D Andersen Jennifer M Hanna Richard L McCann 老启芳 2015中国普通外科杂志2015,24,6:2
10Lymphoepithelial cysts and cystic lymphangiomas: Underrecognized benign cystic lesions of the pancreas显示文摘AIM: To identify their diagnostic and prognostic clinical characteristics in a large series.METHODS: Retrospective review of clinicopathologic and imaging characteristics of patients diagnosed with lymphoepithelial cysts and cystic lymphangiomas of the pancreas at Massachusetts General Hospital.RESULTS: Twelve patients were identified between 1/1/1997 and 8/1/2007. Their median age was 55.5 years(range 19-78 years), and 6 were females. The le-sion was incidentally discovered in half of the patients.Contrast enhanced computed tomography demonstrat-ed that the cysts had thin walls, without calcifications, pancreatic duct dilation or pancreatic parenchyma inva-sion. Endoscopic ultrasound with fine needle aspiration(EUS/FNA) confirmed the diagnosis of a lymphoepithe-lial cyst in 3 patients, one of whom was spared an op-eration and continues to do well after 6 years. Eleven patients had a resection: 3 pancreaticoduodenecto-mies, 7 distal pancreatectomies, and 1 enucleation. The median size of the cysts was 3 cm(range 2-20 cm). At a median follow-up of 57 mo no recurrences or other pancreas-related conditions occurred.CONCLUSION: Lymphoepithelial cysts and cystic lymphangiomas of the pancreas can be diagnosed with a combination of contrast-enhanced computed tomog-raphy scans and EUS/FNA. If the lesion is asymptom-atic, an operation might be avoided.Ioannis T Konstantinidis Avinash Kambadakone Onofrio A Catalano Dushyant V Sahani Vikram Deshpe David G Forcione Jennifer A Wargo Carlos Fernandez-del Castillo Keith D Lillemoe Andrew L Warshaw Cristina R Ferrone 2014World Journal of Gastrointestinal Surgery2014,6,7:2
