1评估大气细颗粒物暴露引起的全球疾病负担的一个综合风险函数显示文摘[背景]评估由于环境空气中细颗粒物(PM2.5)长期暴露引起的疾病负担,需要了解相对风险度(RR)函数的图形和幅度。然而,在世界上很多观察到高PM2.5环境浓度的地方,都缺乏足够的直接证据确定死亡RR函数的图形。[目的]建立可用于全球PM2.5暴露范围内成人死因的RR函数:缺血性心脏病(IHD)、脑血管疾病(脑卒中)、慢性阻塞性肺病(COPD)和肺癌(LC)。建立急性下呼吸道感染(ALRI)发病的RR函数,用于估算〈5岁的儿童中死亡率和健康生活损失年数。[方法]通过整合现有的来自于环境空气污染(AAP)、二手烟草烟雾、家用固体烹饪用燃料和主动吸烟(AS)等研究的RR信息,拟合综合暴露-反应(IER)模型。采用颗粒物质的吸入剂量,通过转化AS暴露来估计全年PM2.5的暴露当量。在估算全球环境PM2.5浓度的基础上,得出各国的人群归因分数(PAFs)。[结果]与以往负担评估中使用的其他7种模型相比,IER模型是一种优越的RR预测方法。在不同国家中,归因于AAP暴露的PAF百分数各不相同,分别为:IHD,2~41;脑卒中,1~43;COPD,〈1~21;LC,〈1~25;ALRI,〈1~38。[结论]我们建立了一种以细颗粒物为基础的RR模型,它通过整合来自不同类型的燃烧所产生颗粒物排放的RR信息,涵盖全球范围的暴露。当获得新的RR信息时,可以对这个模型进行更新。Richard T.Burnett C.Arden Pope III Majid Ezzati Casey Olives Stephen S.Lim Sumi Mehta Hwashin H.Shin Gitanjali Singh Bryan Hubbell Michael Brauer H.Ross Anderson Kirk R.Smith John R.Balmes Nigel G.Bruce Haidong Kan Francine Laden Annette Prüss-Ustün Michelle C.Turner Susan M.Gapstur W.Ryan Diver Aaron Cohen 何蓉 张伊人 金泰廙 2014环境与职业医学2014,31,11:80
2Selective embolization for bleeding visceral artery pseudoaneurysms in patients with pancreatitis显示文摘BACKGROUND:Pancreatitis is associated with arterial complications in 4%-10%of patients,with untreated mortality approaching 90%.Timely intervention at a specialist center can reduce the mortality to 15%.We present a single institution experience of selective embolization as first line management of bleeding pseudoaneurysms in pancreatitis. METHODS:Sixteen patients with pancreatitis and visceral artery pseudoaneurysms were identified from searches of the records of interventional angiography from January 2000 to June 2007.True visceral artery aneurysms and pseudoaneurysms arising as a result of post-operative pancreatic or biliary leak were excluded from the study. RESULTS:In 50%of the patients,bleeding complicated the initial presentation of pancreatitis.Alcohol was the offending agent in 10 patients,gallstones in 3,trauma,drug-induced and idiopathic pancreatitis in one each.All 16 patients had a contrast CT scan and 15 underwent coeliac axis angiography. The pseudoaneurysms ranging from 0.9 to 9.0 cm affected the splenic artery in 7 patients:hepatic in 3,gastroduodenal and right gastric in 2 each,and left gastric and pancreatico-duodenal in 1 each.One patient developed spontaneous thrombosis of the pseudoaneurysm.Fourteen patients had effective coil embolization of the pseudoaneurysm.One patient needed surgical exclusion of the pseudoaneurysm following difficulty in accessing the coeliac axis radiologically.There were no episodes of re-bleeding and no in-hospital mortality. CONCLUSIONS:Pseudoaneurysms are unrelated to the severity of pancreatitis and major hemorrhage can occur irrespective of their size.Co-existent portal hypertension and sepsis increase the risk of surgery.Angiography and selective coil embolization is a safe and effective way to arrest the hemorrhage.Harsheet Sethi Praveen Peddu Andreas Prachalias Pauline Kane John Karani Mohamed Rela Nigel Heaton 2010Hepatobiliary & Pancreatic Diseases International2010,9,6:12
3A history of high-power laser research and development in the United Kingdom显示文摘The first demonstration of laser action in ruby was made in 1960 by T.H.Maiman of Hughes Research Laboratories,USA.Many laboratories worldwide began the search for lasers using different materials,operating at different wavelengths.In the UK,academia,industry and the central laboratories took up the challenge from the earliest days to develop these systems for a broad range of applications.This historical review looks at the contribution the UK has made to the advancement of the technology,the development of systems and components and their exploitation over the last 60 years.Colin N.Danson Malcolm White John R.M.Barr Thomas Bett Peter Blyth David Bowley Ceri Brenner Robert J.Collins Neal Croxford A.E.Bucker Dangor Laurence Devereux Peter E.Dyer Anthony Dymoke-Bradshaw Christopher B.Edwards Paul Ewart Allister I.Ferguson John M.Girkin Denis R.Hall David C.Hanna Wayne Harris David I.Hillier Christopher J.Hooker Simon M.Hooker Nicholas Hopps Janet Hull David Hunt Dino A.Jaroszynski Mark Kempenaars Helmut Kessler Sir Peter L.Knight Steve Knight Adrian Knowles Ciaran L.S.Lewis Ken S.Lipton Abby Littlechild John Littlechild Peter Maggs Graeme P.A.Malcolm OBE Stuart P.D.Mangles William Martin Paul McKenna Richard O.Moore Clive Morrison Zulfikar Najmudin David Neely Geoff H.C.New Michael J.Norman Ted Paine Anthony W.Parker Rory R.Penman Geoff J.Pert Chris Pietraszewski Andrew Randewich Nadeem H.Rizvi Nigel Seddon MBE Zheng-Ming Sheng David Slater Roland A.Smith Christopher Spindloe Roy Taylor Gary Thomas John W.G.Tisch Justin S.Wark Colin Webb S.Mark Wiggins Dave Willford Trevor Winstone 2021High Power Laser Science and Engineering2021,9,2:5

5Developing a donation after cardiac death risk index for adult and pediatric liver transplantation显示文摘AIM To identify objective predictive factors for donor after cardiac death(DCD) graft loss and using those factors, develop a donor recipient stratification risk predictive model that could be used to calculate a DCD risk index(DCD-RI) to help in prospective decision making on organ use.METHODS The model included objective data from a single institute DCD database(2005-2013, n = 261). Univariate survival analysis was followed by adjusted Cox-regressional hazard model. Covariates selected via univariate regression were added to the model via forward selection, significance level P = 0.3. The warm ischemic threshold was clinically set at 30 min. Points were given to each predictor in proportion to their hazard ratio. Using this model, the DCD-RI was calculated. The cohort was stratified to predict graft loss risk and respective graft survival calculated.RESULTS DCD graft survival predictors were primary indication for transplant(P = 0.066), retransplantation(P = 0.176), MELD > 25(P = 0.05), cold ischemia > 10 h(P = 0.292) and donor hepatectomy time > 60 min(P = 0.028).According to the calculated DCD-RI score three risk classes could be defined of low(DCD-RI < 1), standard(DCD-RI 2-4) and high risk(DCD-RI > 5) with a 5 years graft survival of 86%, 78% and 34%, respectively.CONCLUSION The DCD-RI score independently predicted graft loss(P < 0.001) and the DCD-RI class predicted graft survival(P < 0.001).Shirin Elizabeth Khorsandi Emmanouil Giorgakis Hector Vilca-Melendez John O'Grady Michael Heneghan Varuna Aluvihare Abid Suddle Kosh Agarwal Krishna Menon Andreas Prachalias Parthi Srinivasan Mohamed Rela Wayel Jassem Nigel Heaton 2017World Journal of Transplantation2017,7,3:3

8Liver resection for the treatment of a congenital intrahepatic portosystemic venous shunt显示文摘Intrahepatic portosystemic shunts(IPSS) are rare congenital anomalies arising from disordered portal vein embryogenesis.It has been described in both children and adults and may be asymptomatic or be associated with a variety of neurophysiological and pulmonary complications.When recognized,early intervention to occlude the shunt will reverse the associated complications.Literature review reports of surgical and radiological occlusion of the shunt,but due to its rarity,a standard therapeutic protocol has not been established.A case of a 38-year-old woman with abdominal pain and low grade encephalopathy,diagnosed with an IPSS and treated by right hepatectomy was reported.michail papamichail amir ali alberto quaglia john karani nigel heaton 2016Hepatobiliary & Pancreatic Diseases International2016,15,3:2
