1Application of polyurethane geocomposites to help maintain track geometry for high-speed ballasted railway tracks显示文摘There are many issues surrounding the performance of critical assets on high-speed ballasted railway lines.At assets like switch & crossings and bridge transitions high track forces can be produced resulting in higher ballast settlements and hence track misalignments.The latter result in higher track forces and hence more settlement,leading to the need for increased track maintenance to ensure comfort and safety.Current technologies for solving issues like ballast movement under high-speed loading regimes are limited.However,a technique that has been well used across the UK and now increasingly overseas to stabilise and reinforce ballasted railway tracks is the application of in-situ polyurethane polymers,termed XiTRACK.This paper discusses how this technique can be used to solve these types of long-standing issues and presents actual polymer application profiles at two typical critical sites,namely a junction and a transition onto concrete slab-track.Peter Keith WOODWARD Abdellah EL KACIMI Omar LAGHROUCHE Gabriela MEDERO Meysam BANIMAHD 2012Journal of Zhejiang University-Science A(Applied Physics & Engineering)2012,13,11:20

3男性与女性糖尿病患者致死性冠心病的额外危险:37个前瞻性队列研究的汇总分析显示文摘目的:估计男性和女性糖尿病患者致死性冠心病的相对危险。设计:前瞻性队列研究的汇总分析。数据来源:自1966年至2005年3月间Embase和Medline确认并发表的研究,加上源自亚太队列研究协作组的研究,采用正文词组与MeSH主题词相结合的策略进行检索。综述方法:对入选研究的要求为报告有或无糖尿病的男性与女性致死性冠心病的相对危险比较的估计值。如果对估计值仅做年龄调整(而其它因素来经调整——泽者注),则将该研究排除在外。结果:总共纳入37项2型糖尿病和致死性冠心病的研究,涉及447064例患者。糖尿病患者的致死性冠心病发生率显著高于非糖尿病患者(5.4%比1.6%)。与无糖尿病者相比,糖尿病患者发生致死性冠心病的总的相对危险,女性为3.50,95%可信区间为2.70~4.53,显著高于男性患者(2.06,95%可信区间1.81~2.34)。在除外8项仅根据年龄调整的研究后,两性之间危险的差异大大减小,但仍然具有极显著统计学意义。汇集29项经多因素调整估计值的研究,总的相对危险比(女性比男性)为1.46(1.14~1.88)。结论:糖尿病相关的致死性冠心病相对危险,女性比男性高出50%。这种额外的冠心病危险可以通过女性糖尿病患者具有更多不利的心血管危险因素特点以及倾向于对男性患者更注重治疗的可能偏差来解释。Rachel Huxley Federica Barzi Mark Woodward 杨靓(译) 刘靖(校) 2006英国医学杂志中文版2006,9,3:9

8Total pancreatectomy: Short- and long-term outcomes at a high-volume pancreas center显示文摘AIM To identify the current indications and outcomes of total pancreatectomy at a high-volume center. METHODS A single institutional retrospective study of patients undergoing total pancreatectomy from 1995 to 2014 was performed.RESULTS One hundred and three patients underwent totalpancreatectomy for indications including: Pancreatic ductal adenocarcinoma(n = 42, 40.8%), intraductal papillary mucinous neoplasms(n = 40, 38.8%), chronic pancreatitis(n = 8, 7.8%), pancreatic neuroendocrine tumors(n = 7, 6.8%), and miscellaneous(n = 6, 5.8%). The mean age was 66.2 years, and 59(57.3%) were female. Twenty-four patients(23.3%) underwent a laparoscopic total pancreatectomy. Splenic preservation and portal vein resection and reconstruction were performed in 24(23.3%) and 18 patients(17.5%), respectively. The 90 d major complications, readmission, and mortality rates were 32%, 17.5%, and 6.8% respectively. The 1-, 3-, 5-, and 7-year survival for patients with benign indications were 84%, 82%, 79.5%, and 75.9%, and for malignant indications were 64%, 40.4%, 34.7% and 30.9%, respectively.CONCLUSION Total pancreatectomy, including laparoscopic total pancreatectomy, appears to be an appropriate option for selected patients when treated at a high-volume pancreatic center and through a multispecialty approach.Hazem M Zakaria John A Stauffer Massimo Raimondo Timothy A Woodward Michael B Wallace Horacio J Asbun 2016World Journal of Gastrointestinal Surgery2016,8,9:3
9Accelerated infliximab infusions for inflammatory bowel disease improve effectiveness显示文摘AIM:To study the safety and effectiveness associated with accelerated infliximab infusion protocols in patients with inflammatory bowel disease(IBD).METHODS:Original protocols and infusion rates were developed for the administration of infliximab over 90-min and 60-min.Then the IBD patients on stable maintenance infliximab therapy were offered accelerated infusions.To be eligible for the study,patients needed a minimum of four prior infusions.An initial infusion of 90-min was given to each patient;those tolerating the accelerated infusion were transitioned to a 60-min infusion protocol at their next and all subsequent visits.Any patient having significant infusion reactions would be reverted to the standard 120-min protocol.A change in a patient's dose mandated a single 120-min infusion before accelerated infusions could be administered again.RESULTS:The University of Virginia Medical Center's Institutional Review Board approved this study.Fifty IBD patients treated with infliximab 5mg/kg,7.5mg/kg and 10mg/kg were offered accelerated infusions.Forty-six patients consented to participate in the study.Nineteen(41.3%) were female,five(10.9%) were African American and nine(19.6%) had ulcerative colitis.The mean age was 42.6 years old.Patients under age 18 were excluded.Ten patients used immunosuppressive drugs concurrently out of which six were taking azathioprine,three were taking 6-mercaptopurine and one was taking methotrexate.One of the 46 study patients used corticosteroid therapy for his IBD.Seventeen of the patients used prophylactic medications prior to receiving infusions;six patients received corticosteroids as pre-medication.Four patients had a history of distant transfusion reactions to infliximab.These reactions included shortness of breath,chest tightness,flushing,pruritus and urticaria.These patients all took prophylactic medications before receiving infusions.46 patients(27 males and 19 females) received a total of fifty 90-min infusions and ninety-three 60-min infusions.No infusion reactions were reported.There were no adverse events,including drug-related infections.None of the patients developed cancer of any type during the study timeframe.Total cost savings for administration of the both 90-min and 60-min accelerated infusions compared to standard 120-min infusions was estimated to be $53 632($116 965 vs $63 333,P=0.001).One hundred and eighteen hours were saved in the administration of the accelerated infusions(17 160 min vs 10 080 min,P=0.001).In the study population,overweight females [body mass index(BMI)>25.00kg/m2] were found to have statistically higher BMIs than overweight males(mean BMI 35.07±2.66kg/m2 vs 30.08±0.99kg/m2,P=0.05),finding which is of significance since obesity was described as being one of the risk factors for Crohn's disease.CONCLUSION:We are the first US group to report substantial cost savings,increased safety and patient satisfaction associated with accelerated infliximab infusion.John McConnell Simona Parvulescu-Codrea Brian Behm Beth Hill Elizabeth Dunkle Karen Finke Kathryn Snyder Anne Tuskey Debbie Cox Beth Woodward 2012World Journal of Gastrointestinal Pharmacology and Therapeutics2012,3,5:2
