1Beyond the Pediatric end-stage liver disease system: Solutions for infants with biliary atresia requiring liver transplant显示文摘Biliary atresia(BA), a chronic progressive cholestatic disease of infants, is the leading cause for liver transplant in children, especially in patients under two years of age. BA can be successfully treated with the Kasai portoenterostomy; however most patients still require a liver transplant, with up to one half of BA children needing a transplant by age two. In the current pediatric end-stage liver disease system, children with BA face the risk of not receiving a liver in a safe and timely manner. In this review, we discuss a number of possible solutions to help these children. We focus on two general approaches:(1) preventing/delaying need for transplantation, by optimizing the success of the Kasai operation; and(2) expediting transplantation when needed, by performing techniques other than the standard deceased-donor, whole, ABO-matched organ transplant.Mary Elizabeth M Tessier Sanjiv Harpavat Ross W Shepherd Girish S Hiremath Mary L Brandt Amy Fisher John A Goss 2014World Journal of Gastroenterology2014,20,32:14

3Relationship between the exocrine and endocrine pancreas after acute pancreatitis显示文摘AIM:To determine the prevalence and time course of pancreatic exocrine insufficiency in individuals with newly diagnosed prediabetes or diabetes mellitus after acute pancreatitis.METHODS:Relevant literature cited in three major biomedical journal databases(EMBASE,MEDLINE,and Scopus)was reviewed independently by two authors.There were no language constraints but the search was limited to human studies.Studies included were cohort studies of adult patients who were discharged after an attack of acute pancreatitis.Patients were excluded if they were under 18 years of age or had a previous diagnosis of prediabetes or diabetes mellitus,pancreatic exocrine insufficiency,or chronic pancreatitis.The main outcome measure was the prevalence of concomitant pancreatic exocrine insufficiency in patients who were diagnosed with prediabetes and diabetes mellitus after an attack of acute pancreatitis.Subgroup analysis was conducted for patients who were diagnosed with prediabetes only and those who were diagnosed withdiabetes mellitus only.Subgroup analysis looking at the time course of concomitant pancreatic exocrine and endocrine insufficiency was also conducted.Pooled prevalence and corresponding 95%confidence intervals were calculated for all outcome measures and P-values<0.05 were deemed statistically significant.RESULTS:Eight clinical studies comprising of 234patients met all eligibility criteria.The pooled prevalence of newly diagnosed prediabetes or diabetes in individuals after acute pancreatitis was 43%(95%CI:30%-56%).The pooled prevalence of pancreatic exocrine insufficiency in individuals after acute pancreatitis was 29%(95%CI:19%-39%).The prevalence of concomitant pancreatic exocrine insufficiency in individuals with newly diagnosed prediabetes or diabetes was 40%(95%CI:25%-55%).The prevalence of concomitant pancreatic exocrine insufficiency among individuals with prediabetes alone and diabetes mellitus alone was 41%(95%CI:12%-75%)and 39%(95%CI:28%-51%),respectively.Further analysis showed that the prevalence of concomitant pancreatic exocrine insufficiency in individuals with prediabetes or diabetes decreases over time after an attack of acute pancreatitis.CONCLUSION:Pancreatic exocrine insufficiency occurs in 40%of individuals with newly diagnosed prediabetes or diabetes mellitus after acute pancreatitis.Further studies are needed to investigate the pathogenesis of diabetes in this setting.Stephanie L M Das James I C Kennedy Rinki Murphy Anthony R J Phillips John A Windsor Maxim S Petrov 2014World Journal of Gastroenterology2014,20,45:9
4Characterization of a critical role for CFTR chloride channels in cardioprotection against ischemia/ reperfusion injury显示文摘目的: 进一步描绘膀胱的纤维变性 transmembrane 传导力管理者(CFTR ) 的功能的角色在早、迟了(第二扇窗户) ischemic preconditioning (欧洲电脑生产厂商)- 并且 postconditioning (停靠港) 调停了对 ischemia/reperfusion (I/R ) 的 cardioprotection 损害。Sunny Yang XIANG Linda L YE Li-lu Marie DUAN Li-hui LIU Zhi-dong GE John A AUCHAMPACH Garrett J GROSS Dayue Darrel DUAN 2011Acta Pharmacologica Sinica2011,32,6:9
5Effect of music on patients undergoing outpatient colonoscopy显示文摘AIM: To evaluate the effect of relaxing music during colonoscopy under low-dose conscious sedation, on patient satisfaction, scope insertion time and procedure duration, medication doses, and the perceived adequacy of sedation and scope insertion difficulty on the part of the endoscopist. METHODS: One hundred and sixty-seven consecutive adult outpatients presenting for routine colonoscopy under low-dose conscious sedation were randomized to undergo their procedures either with music played during the procedure or no music played. RESULTS: There were no statistical differences between the two groups in terms of meperidine dose, midazolam dose, time to reach the cecum, total procedure time, endoscopist assessment of scope insertion difficulty, endoscopist assessment of adequacy of sedation, or the pain experience of the patients during their procedure. The music group did report significantly better overall procedure satisfaction as compared to the non music group on two of our three different scales. CONCLUSION: While music does not result in shortened procedure times, lower doses of sedative medications or perceived patient pain, the patients who have music playing during their procedures report modestly greater satisfaction with their procedures.Matthew L Bechtold Rodney A Perez Srinivas R Puli John B Marshall 2006World Journal of Gastroenterology2006,12,45:8
6Near-infrared fluorescence imaging of a solitary fibrous tumor of the pancreas using methylene blue显示文摘A 67-year-old female presented with unexplained abdominal pain. A contrast-enhanced computed tomography scan of the abdomen incidentally revealed a mass in the uncinate process of the pancreas. This mass was resected and based on histopathological findings, diagnosed as a solitary fibrous tumor (SFT) of the pancreas. A SFT is an extremely rare benign mesenchymal tumor that in 65% of cases affects the visceral pleura but can also affect extra-pleural sites. The intraoperative demarcation of pancreatic tumors, such as SFTs, can bechallenging. In this report, the first clear intraoperative identification of a SFT of the pancreas in a human was shown using near-infrared fluorescence and methylene blue.Joost R van der Vorst Alexander L Vahrmeijer Merlijn Hutteman Tjalling Bosse Vincent THBM Smit Cornelis JH van de Velde John V Frangioni Bert A Bonsing 2012World Journal of Gastrointestinal Surgery2012,4,7:7
7抗炎介质表达缺陷参与中性粒细胞型支气管哮喘发病机制:半乳糖凝集素-3和白细胞介素-1RA/白细胞介素-1beta比例显著下降显示文摘支气管哮喘(哮喘)是具有异质性的气道炎症性疾病,其主要特点表现为气道高反应和可变的气流受限。在哮喘的发病机制中,过敏原诱导的TH2淋巴细胞激活以及IL-5介导的嗜酸粒细胞渗出起到重要的作用。近年来发现超过50%的哮喘患者气道的嗜酸粒细胞水平并不增高,并将这种亚型定义为非嗜酸粒细胞型哮喘。其中部分患者表现为气道中性粒细胞明显增高,称为中性粒细胞型哮喘。高鹏 Peter G Gibson Katherine J Baines Ian A Yang John W Upham Paul N Reynolds Sandra Hodge Alan L James Christine Jenkins Matthew J Peters 张捷 Jodie L Simpson 2016中华结核和呼吸杂志2016,39,11:5
8针对患者利益的机器学习和人工智能研究:在透明性、可重复性、伦理和有效性等方面的20个关键问题显示文摘机器学习(ML)、人工智能(AI)和其他现代统计方法正为利用先前尚未开发且极速增长的数据资源提供新的机会,以期让患者获益。尽管目前正在进行许多有前景的研究,特别是在图像方面,但就文献整体而言还缺乏透明度、对可重复性清晰的阐述、对潜在伦理问题的探究,以及对有效性的明确验证。这些问题的存在有许多原因,其中最重要的一点(为此我们提供了初步解决方案)就是当前缺乏针对ML和AI的最佳实践指南。我们认为从事研究的跨学科团队和应用ML/AI影响健康的项目,将因解决有关透明度、可重复性、伦理和有效性(TREE)的一系列问题而受益。这里提出的20个关键问题为研究团队提供了一个研究设计、实施和报告框架;帮助编辑和同行评审专家评估文献的贡献;让患者、临床医生和政策制定者评估新发现可能会给患者带来的获益。Sebastian Vollmer Bilal A Mateen Gergo Bohner Franz J Kirdly Rayid Ghani Pall Jonsson Sarah Cumbers Adrian Jonas Katherine S L McAllister Puja Myles David Granger Mark Birse Richard Branson Karel G M Moons Gary S Collins John P A Chris Holmes Harry Hemingwayp 李峰(译) 徐磊(校) 赵邑(校) 2020英国医学杂志中文版2020,23,9:5

11全球药物滥用的疾病负担:来自2010年全球疾病负担研究显示文摘背景:直到目前还没有研究者系统地估计过全球及区域性的苯丙胺类、大麻、可卡因和阿片类药物依赖的患病率及其造成的疾病负担。我们旨在用伤残损失寿命年(YLDs)、过早死亡损失寿命年(YLLs)和伤残调整寿命年(DALYs)来估计药物依赖的患病率和其造成的疾病负担。方法:采用贝叶斯Meta回归的方法(Dis Mod-MR)对药物依赖的流行病学研究及2010年全球疾病、伤害及危险因素负担研究(GBD 2010)进行了系统综述,估计人群水平的药物依赖患病率。GBD 2010通过代表性社区调查和基于互联网的调查计算出新的失能权重。我们把估计的药物依赖患病率和新的失能权重结合起来估算药物依赖导致的YLDs、YLLs、DALYs和其作为相关疾病危险因素时导致的YLDs、YLLs和DALYs。结果:2010年,药物依赖直接造成了2千万的DALYs(95%UI(不确定区间)1.3-2.54千万),占全球全因DALYs的0.8%(0.6%-1.0%)。世界范围内,相比于其他药物,越来越多的人依赖于阿片类和苯丙胺类药物。阿片类药物依赖直接造成的疾病负担最大(DALYs为920万,95%UI为710-1140万)。在某些地区,药物依赖导致的DALYs所占比例比其他地区高出20倍,收入越高的国家药物依赖造成的负担所占比例也越高。注射吸毒所致HIV感染造成210万的DALYs(95%UI 110-360万),所致HCV感染导致50.2万的DALYs(95%UI 28.6-89.1万)。苯丙胺类药物依赖所致自杀造成85.4万的DALYs(95%UI 29.1-179.1万),阿片类药物依赖所致自杀造成67.1万的DALYs(95%UI 32.9-173.0万),可卡因依赖所致自杀造成32.4万的DALYs(95%UI 10.9-68.2万)。药物依赖导致的疾病负担最高的国家(>650 DALYs/10万人)包括美国,英国,俄罗斯和澳大利亚。结论:药物滥用是造成全球疾病负担的一个重要因素。为减少人群水平的疾病负担,我们需采取有效的措施(比如给予阿片类药物依赖者替代治疗及针具交换等)降低阿片类药物依赖和注射吸毒导致的疾病负担。王同瑜 Degenhardt L Whiteford HA Ferrari AJ Baxter AJ Charlson FJ Hall WD Freedman G Burstein R Johns Engell RE Flaxman A Murray CJ Vos T 2015中国药物依赖性杂志2015,24,6:3
12Th1 cytokines promote T-cell binding to antigen-presenting cells via enhanced hyaluronan production and accumulation at the immune synapse显示文摘Hyaluronan(HA)production by dendritic cells(DCs)is known to promote antigen presentation and to augment T-cell activation and proliferation.We hypothesized that pericellular HA can function as intercellular‘glue’directly mediating T cell–DC binding.Using primary human cells,we observed HA-dependent binding between T cells and DCs,which was abrogated upon pre-treatment of the DCs with 4-methylumbelliferone(4-MU),an agent which blocks HA synthesis.Furthermore,T cells regulate HA production by DCs via T cell-derived cytokines in a T helper(Th)subset-specific manner,as demonstrated by the observation that cell-culture supernatants from Th1 but not Th2 clones promote HA production.Similar effects were seen upon the addition of exogenous Th1 cytokines,IL-2,interferon c(IFN-c)and tumor necrosis factor a(TNF-a).The critical factors which determined the extent of DC–T cell binding in this system were the nature of the pre-treatment the DCs received and their capacity to synthesize HA,as T-cell clones which were pre-treated with monensin,added to block cytokine secretion,bound equivalently irrespective of their Th subset.These data support the existence of a feedforward loop wherein T-cell cytokines influence DC production of HA,which in turn affects the extent of DC–T cell binding.We also document the presence of focal deposits of HA at the immune synapse between T-cells and APC and on dendritic processes thought to be important in antigen presentation.These data point to a pivotal role for HA in DC–T cell interactions at the IS.Paul L Bollyky Stephen P Evanko Rebecca P Wu Susan Potter-Perigo S Alice Long Brian Kinsella Helena Reijonen Kelly Guebtner Brandon Teng Christina K Chan Kathy R Braun John A Gebe Gerald T Nepom Thomas N Wight 2010Cellular & Molecular Immunology2010,7,3:3

15Perforated jejunal ulcer associated with gastric mucosa in a jejunal diverticulum显示文摘Jejunal diverticula are rare and subsequent complications even more so. The usual small bowel diverticulum encountered by general surgeons is a Meckel's. These are embryological remnants of the vitello-intestinal duct and are on the anti-mesenteric surface of the terminal ileum. They may contain heterotopic gastric or pancreatic mucosa. Herein we explore the case of a young girl who presented with features of peritonitis secondary to a complication from a jejunal diverticulum. The case, pathology, complications and treatment of jejunal diverticulosis and heterotopic gastric mucosa in the jejunum are explored.John Bunni Helen L Barrett Tim A Cook 2014World Journal of Clinical Cases2014,2,6:2

17Clinical decision support for drug related events: Moving towards better prevention显示文摘Clinical decision support(CDS) systems with automated alerts integrated into electronic medical records demonstrate efficacy for detecting medication errors(ME) and adverse drug events(ADEs). Critically ill patients are at increased risk for ME, ADEs and serious negative outcomes related to these events. Capitalizing on CDS to detect ME and prevent adverse drug related events has the potential to improve patient outcomes. The key to an effective medication safety surveillance system incorporating CDS is advancing the signals for alerts by using trajectory analyses to predict clinical events, instead of waiting for these events to occur. Additionally, incorporating cutting-edge biomarkers into alert knowledge in an effort to identify the need to adjust medication therapy portending harm will advance the current state of CDS. CDS can be taken a step further to identify drug related physiological events, which are less commonly included in surveillance systems. Predictive models for adverse events that combine patient factors with laboratory values and biomarkers are being established and these models can be the foundation for individualized CDS alerts to prevent impending ADEs.Sandra L Kane-Gill Archita Achanta John A Kellum Steven M Handler 2016World Journal of Critical Care Medicine2016,5,4:2

20Personalising pancreas cancer treatment:When tissue is the issue显示文摘The treatment of advanced pancreatic cancer has not moved much beyond single agent gemcitabine until recently when protocols such as FOLFIRINOX(fluorouracil,leucovorin,irinotecan and oxaliplatin)and nab-paclitaxelgemcitabine have demonstrated some improved outcomes.Advances in technology especially in massively parallel genome sequencing has progressed our understanding of the biology of pancreatic cancer especially the candidate signalling pathways that are involved in tumourogenesis and disease course.This has allowed identification of potentially actionable mutations that may be targeted by new biological agents.The heterogeneity of pancreatic cancer makes tumour tissue collection important with the aim of being able to personalise therapies for the individual as opposed to a one size fits all approach to treatment of the condition.This paper reviews the developments in this area of translational research and the ongoing clinical studies that will attempt to move this into the everyday oncology practice.Katrin M Sjoquist Venessa T Chin Lorraine A Chantrill Chelsie O'Connor Chris Hemmings David K Chang Angela Chou Marina Pajic Amber L Johns Adnan M Nagrial Andrew V Biankin Desmond Yip 2014World Journal of Gastroenterology2014,20,24:2
