1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

3Digital templating in total hip arthroplasty:Additional anteroposterior hip view increases the accuracy显示文摘AIM To analyze planning total hip arthroplasty(THA) with an additional anteroposterior hip view may increases the accuracy of preoperative planning in THA.METHODS We conducted prospective digital planning in 100 consecutive patients: 50 of these procedures were planned using pelvic overview only(first group), and the other 50 procedures were planned using pelvic overview plus antero-posterior(a.p.) hip view(second group). The planning and the procedure of each patient were performed exclusively by the senior surgeon. Fifty procedures with retrospective analogues planning were used as the control group(group zero). After the procedure, the planning was compared with the eventually implanted components(cup and stem). For statistic analysis the x^2 test was used for nominal variables and the t test was used for a comparison of continuous variables.RESULTS Preoperative planning with an additional a.p. hip view(second group) significantly increased the exact component correlation when compared to pelvic overview only(first group) for both the acetabular cup and the femoral stem(76% cup and 66% stem vs 54% cup and 32% stem). When considering planning ± 1 size, the accuracy in the second group was 96%(48 of 50 patients) for the cup and 94% for the stem(47 of 50patients). In the analogue control group(group zero), an exact correlation was observed in only 1/3 of the cases.CONCLUSION Digital THA planning performed by the operating surgeon and based on additional a.p. hip view significantly increases the correlation between preoperative planning and eventual implant sizes.Sophia K Stigler Franz J Müller Sebastian Pfaud Michael Zellner Bernd Füchtmeier 2017World Journal of Orthopedics2017,8,1:3
4Proteome alterations in aqueous humour of primary open angle glaucoma patients显示文摘AIM: To unravel the primary open angle glaucoma(POAG) related proteomic changes in aqueous humour(AH).METHODS: Totally 35 patients listed for cataract surgery(controls: n=12, age: 67.4±13.6 y) or trabeculectomy for POAG(n=23, age: 72.5±8.3 y) were included. AH samples of those patients were obtained during cataract surgery or trabeculectomy. AH samples were subsequently pooled into the experimental groups under equal contribution in terms of protein amount of each individual patient. Protein samples were analyzed by a linear trap quadrupol Orbitrap Mass Spectrometry device with an upstream liquid chromatography system. The obtained raw data were analyzed using the Maxquant proteome software and compared. Proteins with a fold-change ratio higher than a cut-off of 2 were considered as noticeably altered.RESULTS: A total number of 175 proteins could be identified out of the AH from POAG and cataract by means of quantitative mass spectrometric analysis. Apolipoprotein D(fold change, 3.16 times), complement C3(2.96), pigment epithelium-derived factor(2.86), dickkopf-related protein 3(2.18) and wingless-related integration(Wnt) inhibitory factor 1(2.35) were significantly upregulated within the AH of glaucoma compared to cataract serving as controls.CONCLUSION: AH provides a tool to analyze changes in glaucoma and shows striking changes in Wnt signaling inhibitory molecules and other proteins.Hanhan Liu Fabian Anders Sebastian Funke Karl Mercieca Franz Grus Verena Prokosch 2020International Journal of Ophthalmology(English edition)2020,13,1:2
5An automated, 0.5 Hz nano-foil target positioning system for intense laser plasma experiments显示文摘We report on a target system supporting automated positioning of nano-targets with a precision resolution of 4 μm in three dimensions. It relies on a confocal distance sensor and a microscope. The system has been commissioned to position nanometer targets with 1 Hz repetition rate. Integrating our prototype into the table-top ATLAS 300 TW-laser system at the Laboratory for Extreme Photonics in Garching, we demonstrate the operation of a 0.5 Hz laser-driven proton source with a shot-to-shot variation of the maximum energy about 27% for a level of confidence of 0.95. The reason of laser shooting experiments operated at 0.5 Hz rather than 1 Hz is because the synchronization between the nano-foil target positioning system and the laser trigger needs to improve.Ying Gao Jianhui Bin Daniel Haffa Christian Kreuzer Jens Hartmann Martin Speicher Florian H.Lindner Tobias M.Ostermayr Peter Hilz Thomas F.Rsch Sebastian Lehrack Franz Englbrecht Sebastian Seuferling Max Gilljohann Hao Ding Wenjun Ma Katia Parodi Jorg Schreiber 2017High Power Laser Science and Engineering2017,5,2:1

15Resilience in Agriculture: Communication and Energy Infrastructure Dependencies of German Farmers显示文摘Agriculture is subject to high demands regarding resilience as it is an essential component of the food production chain. In the agricultural sector, there is an increasing usage of digital tools that rely on communication and energy infrastructures. Should disruption occur,such strengthened dependencies on other infrastructures increase the probability of ripple effects. Thus, there is a need to analyze the resilience of the agricultural sector with a specific focus on the effects of digitalization. This study works out resilience capacities of the interconnected technologies used in farm systems based on the experiences and opinions of farmers. Information was gathered through focus group interviews with farmers(N = 52) and a survey with participants from the agricultural sector(N =118). In particular, the focus is put on the digital tools and other information and communication technologies they use. Based on a definition of resilience capacities, we evaluate resilience regarding energy and communication demands in various types of farm systems. Especially important are the resilience aspects of modern systems’ digital communication as well as the poorly developed and nonresilient network infrastructure in rural areas that contrast with the claim for a resilient agriculture. The result is a low robustness capacity, as our analysis concludes with the risk of food production losses.Franz Kuntke Sebastian Linsner Enno Steinbrink Jonas Franken Christian Reuter 2022International Journal of Disaster Risk Science2022,13,2:0
