1基于信号质量评估和卡尔曼滤波的心率估计算法显示文摘目的:研究基于多导重症监护导联心电分析的逐搏心率估计算法。方法:通过开放源码的QRS搏动识别算法计算逐搏心率,通过分析信号的波形特征、统计特性和相互关系导出反映信号质量好坏的信号质量指数(signalqualityindex,SQI)。应用基于信号质量指数调节的卡尔曼滤波方法进行心率估计,通过残差值和信号质量指数的大小来动态调节卡尔曼滤波器的状态变量,获得逐搏心率的最佳估计。应用美国麻省理工学院多参数智能重症监护数据库II中437例病人的6000多小时高质量数据和人为添加真实心电干扰的数据进行算法评价。结果:与直接心率估计及采样保持等算法比较,本算法在严重干扰存在时,心率估计的均方根误差最小。结论:基于信号质量评估和卡尔曼滤波的心率估计算法在严重干扰存在时仍能提供精确的心率估计。李桥 Roger G Mark Gari D Clifford 俞梦孙 2007中国医学物理学杂志2007,24,6:8

4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
5A 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

10A rare case of Staphylococcus lugdunensis septicemia associated with myocarditis and atrioventricular block显示文摘Myocarditis is a relatively rare,possibly life-threatening disease characterized by the inflammation of the myocardium.111 The disease pathogenesis is primarily initiated by acute injury and necrosis of cardiomyocytes,leading to an inflammatory response mediated by the immune system that can potentially cause further aggravation of myocardial damage and organ dysfunction.Prognosis in patients with myocarditis depends on the clinical presentation,which ranges from an asymptomatic disease course to the concomitant development of cardiac arrhythmias,heart failure,cardiogenic shock and even the occurrence of death in extreme cases[1].Alex Tsz Lai Nganh Sharen Lee Tong LIU Mark Tam Ka Hou Christien Li Michelle Vangi Wong Michael Huen Sum Lam Gary Tse Ishan Lakhani 2019Journal of Geriatric Cardiology2019,16,1:2
