    关于DNA条形码企业历史的这一章试图通过解决以下问题,为本卷中更多的学术贡献奠定基础。DNA条形码企业是如何开始的?它的目标是什么,它是如何发展的,我们对条形码运动及其与分类法的关系产生了浓厚的兴趣,收藏品,和生物多样性信息学更广泛地考虑。本章整合了我们对条形码的两种不同观点。DES在2004年至2017年期间担任生命条形码联盟的执行秘书,其使命是支持DNA条形码的成功,而无需直接参与生成条形码数据。RDMP将条形码视为生物多样性数据的重要入口,与景观的其他组成部分有许多潜在的联系。我们也认为这是朝着国际基因组研究时代迈出的关键一步。就像阿波罗计划为登月铺平了道路的水星计划一样,我们认为DNA条形码是全基因组研究成功所需的跨学科和国际合作的证明基础。
    This chapter on the history of the DNA barcoding enterprise attempts to set the stage for the more scholarly contributions in this volume by addressing the following questions. How did the DNA barcoding enterprise begin? What were its goals, how did it develop, and to what degree are its goals being realized? We have taken a keen interest in the barcoding movement and its relationship to taxonomy, collections, and biodiversity informatics more broadly considered. This chapter integrates our two different perspectives on barcoding. DES was the Executive Secretary of the Consortium for the Barcode of Life from 2004 to 2017, with the mission to support the success of DNA barcoding without being directly involved in generating barcode data. RDMP viewed barcoding as an important entry into the landscape of biodiversity data, with many potential linkages to other components of that landscape. We also saw it as a critical step toward the era of international genomic research that was sure to follow. Like the Mercury Program that paved the way for lunar landings by the Apollo Program, we saw DNA barcoding as the proving grounds for the interdisciplinary and international cooperation that would be needed for success of whole-genome research.

    目的:放射学报告的结论部分对于以自然语言总结主要放射学发现至关重要,对于向临床医生传达结果至关重要。然而,创建这些摘要非常耗时,重复,并且容易在不同的放射科医师之间出现差异和错误。为了解决这些问题,我们评估了一个经过微调的文本到文本转换转换器(T5)模型,用于抽象总结,以便以低资源语言自动生成神经放射学MRI报告的结论.
    方法:我们将我们的方法应用于西班牙语的232,425例神经放射学MRI报告的数据集。我们比较了各种预训练的T5模型,包括多语种T5和新改编的西班牙语。为了精确评估,我们雇佣了BLEU,METEOR,ROUGE-L,CIDEr,和余弦相似性度量以及放射科专家评估。
    结果:研究结果是有希望的,这些模型专门针对神经放射学MRI进行了微调,在BLEU-1,METEOR中得分分别为0.46、0.28、0.52、2.45和0.87,ROUGE-L,CIDEr,和余弦相似性度量,分别。在放射学专家的评估中,他们发现在75%的案例中,系统生成的结论与人工生成的结论一样好,甚至更好。
    结论:这些方法证明了为神经放射学定制最先进的预训练模型的潜力和有效性,产生自动MRI报告结论,几乎符合专家质量。此外,这些结果强调了为放射学报告总结设计和预训练专用语言模型的重要性.
    OBJECTIVE: The conclusion section of a radiology report is crucial for summarizing the primary radiological findings in natural language and essential for communicating results to clinicians. However, creating these summaries is time-consuming, repetitive, and prone to variability and errors among different radiologists. To address these issues, we evaluated a fine-tuned Text-To-Text Transfer Transformer (T5) model for abstractive summarization to automatically generate conclusions for neuroradiology MRI reports in a low-resource language.
    METHODS: We retrospectively applied our method to a dataset of 232,425 neuroradiology MRI reports in Spanish. We compared various pre-trained T5 models, including multilingual T5 and those newly adapted for Spanish. For precise evaluation, we employed BLEU, METEOR, ROUGE-L, CIDEr, and cosine similarity metrics alongside expert radiologist assessments.
    RESULTS: The findings are promising, with the models specifically fine-tuned for neuroradiology MRI achieving scores of 0.46, 0.28, 0.52, 2.45, and 0.87 in the BLEU-1, METEOR, ROUGE-L, CIDEr, and cosine similarity metrics, respectively. In the radiological experts\' evaluation, they found that in 75% of the cases evaluated, the conclusions generated by the system were as good as or even better than the manually generated conclusions.
    CONCLUSIONS: The methods demonstrate the potential and effectiveness of customizing state-of-the-art pre-trained models for neuroradiology, yielding automatic MRI report conclusions that nearly match expert quality. Furthermore, these results underscore the importance of designing and pre-training a dedicated language model for radiology report summarization.

    大型语言模型(LLM)通过将临床发现总结为印象,在加速放射学报告方面显示出希望。然而,全身PET报告的自动印象生成提出了独特的挑战,很少受到关注。我们的研究旨在评估LLM是否可以为PET报告创造临床有用的印象。为此,我们在从我们机构收集的37,370份回顾性PET报告的语料库上微调了12个开源语言模型.所有模型都使用教师强迫算法进行训练,以报告结果和患者信息为输入,以原始临床印象为参考。一个额外的输入令牌编码阅读医生的身份,允许模型学习医生特定的报告风格。为了比较不同型号的性能,我们计算了各种自动评估指标,并根据医生的偏好对其进行了基准测试,最终选择PEGASUS作为顶级LLM。为了评估其临床效用,3名核医学医师在6个质量维度(3分量表)和总体效用评分(5分量表)评估了PEGASUS产生的印象和原始临床印象.每位医生审查了他们自己的12份报告和其他医生的12份报告。当医生评估以自己的风格产生的LLM印象时,89%被认为是临床上可以接受的,平均效用分数为4.08/5。平均而言,医生将这些个性化印象评价为在总体效用上与其他医生指示的印象相当(4.03,P=0.41)。总之,我们的研究表明,在大多数情况下,PEGASUS产生的个性化印象在临床上是有用的,强调其通过自动起草印象来加快PET报告的潜力。
    Large language models (LLMs) have shown promise in accelerating radiology reporting by summarizing clinical findings into impressions. However, automatic impression generation for whole-body PET reports presents unique challenges and has received little attention. Our study aimed to evaluate whether LLMs can create clinically useful impressions for PET reporting. To this end, we fine-tuned twelve open-source language models on a corpus of 37,370 retrospective PET reports collected from our institution. All models were trained using the teacher-forcing algorithm, with the report findings and patient information as input and the original clinical impressions as reference. An extra input token encoded the reading physician\'s identity, allowing models to learn physician-specific reporting styles. To compare the performances of different models, we computed various automatic evaluation metrics and benchmarked them against physician preferences, ultimately selecting PEGASUS as the top LLM. To evaluate its clinical utility, three nuclear medicine physicians assessed the PEGASUS-generated impressions and original clinical impressions across 6 quality dimensions (3-point scales) and an overall utility score (5-point scale). Each physician reviewed 12 of their own reports and 12 reports from other physicians. When physicians assessed LLM impressions generated in their own style, 89% were considered clinically acceptable, with a mean utility score of 4.08/5. On average, physicians rated these personalized impressions as comparable in overall utility to the impressions dictated by other physicians (4.03, P = 0.41). In summary, our study demonstrated that personalized impressions generated by PEGASUS were clinically useful in most cases, highlighting its potential to expedite PET reporting by automatically drafting impressions.

    在放射学报告中纳入比较研究是重要的,标准做法。尽管如此,我们发现,本机构受训人员在下班后提交的初步报告往往忽略了对儿科住院患者便携式射线照片的比较研究的参考.我们通过针对儿科X光片的质量改进项目解决了这个问题。主要干预措施包括通过删除比较字段中的默认文本来修改结构化报表,将比较字段指定为必填字段,并重组报告模板以删除无关信息。我们还发起了有针对性的教育运动。评估了干预前的392例报告和干预后的267例报告(共732例报告),以确定缺乏比较信息的报告数量。在干预之后,在不完整报告中,有统计学显著下降,从12.5%降至6%.该项目突出了利用结构化报告来提高培训生报告质量的成功。
    The inclusion of comparison studies within radiology reports is an important, standard practice. Despite this, we identified that after-hours preliminary reports rendered by trainees within our institution often omitted reference to comparison studies for pediatric inpatient portable radiographs. We addressed this issue through a quality improvement project targeting pediatric radiographs. Key interventions included modifying the structured reports by removing default text in the comparison field, designating the comparison field as mandatory, and restructuring the report templates to remove extraneous information. We also initiated a targeted educational campaign. 392 reports before and 267 reports after intervention (total 732 reports) were evaluated to determine the number of reports lacking comparison information when comparisons were available. Following the interventions, there was a statistically significant decrease in incomplete reports from 12.5% to 6%. This project highlights the success of utilizing structured reporting to improve the quality of trainee reports.

    UNASSIGNED: To determine if fine-tuned large language models (LLMs) can generate accurate, personalized impressions for whole-body PET reports.
    UNASSIGNED: Twelve language models were trained on a corpus of PET reports using the teacher-forcing algorithm, with the report findings as input and the clinical impressions as reference. An extra input token encodes the reading physician\'s identity, allowing models to learn physician-specific reporting styles. Our corpus comprised 37,370 retrospective PET reports collected from our institution between 2010 and 2022. To identify the best LLM, 30 evaluation metrics were benchmarked against quality scores from two nuclear medicine (NM) physicians, with the most aligned metrics selecting the model for expert evaluation. In a subset of data, model-generated impressions and original clinical impressions were assessed by three NM physicians according to 6 quality dimensions (3-point scale) and an overall utility score (5-point scale). Each physician reviewed 12 of their own reports and 12 reports from other physicians. Bootstrap resampling was used for statistical analysis.
    UNASSIGNED: Of all evaluation metrics, domain-adapted BARTScore and PEGASUSScore showed the highest Spearman\'s ρ correlations (ρ=0.568 and 0.563) with physician preferences. Based on these metrics, the fine-tuned PEGASUS model was selected as the top LLM. When physicians reviewed PEGASUS-generated impressions in their own style, 89% were considered clinically acceptable, with a mean utility score of 4.08 out of 5. Physicians rated these personalized impressions as comparable in overall utility to the impressions dictated by other physicians (4.03, P=0.41).
    UNASSIGNED: Personalized impressions generated by PEGASUS were clinically useful, highlighting its potential to expedite PET reporting.

    在一项回顾性单中心研究中,作者评估了自动成像检查分配系统在增强肿瘤成像研究员报告的亚专科检查多样性方面的功效.该研究旨在减轻人工案例选择的传统偏见,并确保公平地接触各种案例类型。方法包括评估系统实施前后研究员报告的“不常见”与“常见”病例的比例,并测量每周的香农多样性指数以确定病例分布公平性。报告的罕见病例比例从8.6%增加到17.7%,增加了一倍以上,以并发9.0%为代价,普通病例从91.3%下降到82.3%。每个研究员的每周香农多样性指数从0.66(95%CI:0.65,0.67)显着增加到0.74(95%CI:0.72,0.75;P<.001),在引入自动分配后,确认研究员之间更平衡的案例分布。©RSNA,2023年关键词:计算机应用,教育,伙计们,信息学,MRI,肿瘤成像。
    In a retrospective single-center study, the authors assessed the efficacy of an automated imaging examination assignment system for enhancing the diversity of subspecialty examinations reported by oncologic imaging fellows. The study aimed to mitigate traditional biases of manual case selection and ensure equitable exposure to various case types. Methods included evaluating the proportion of \"uncommon\" to \"common\" cases reported by fellows before and after system implementation and measuring the weekly Shannon Diversity Index to determine case distribution equity. The proportion of reported uncommon cases more than doubled from 8.6% to 17.7% in total, at the cost of a concurrent 9.0% decrease in common cases from 91.3% to 82.3%. The weekly Shannon Diversity Index per fellow increased significantly from 0.66 (95% CI: 0.65, 0.67) to 0.74 (95% CI: 0.72, 0.75; P < .001), confirming a more balanced case distribution among fellows after introduction of the automatic assignment. © RSNA, 2023 Keywords: Computer Applications, Education, Fellows, Informatics, MRI, Oncologic Imaging.

    意大利政府计划投资150亿欧元的欧洲资金用于国家卫生服务数字化和初级保健增强。大流行给医院护理带来的沉重负担意味着这些投资不能再拖延了,考虑到许多治疗的大量积压和零散的长期护理的普通差距,在意大利和国外。已经发布了国家指南,以规范整个意大利地区的干预措施,远程医疗经常被提到是实现这两个目标的关键创新。非常精确地定义了运行初级保健设施所需的专业资源,但是没有提供有关如何在这种情况下实施数字化和远程护理技术的详细信息。在这个政策案例的基础上,本文关注数字化和远程医疗对特定初级保健创新的贡献,借鉴实施的技术驱动政策,这些政策可能支持有效的分层,预防和管理慢性病患者的需求,包括预期医疗保健,人口健康管理,调整后的临床组,慢性护理管理,质量和成果框架,患者报告的结局和患者报告的经验.所有这些政策都可以从数字化和远程护理技术中受益匪浅,前提是设计考虑了一些风险和限制。
    The Italian Government planned to invest €15 billion of European funds on National Health Service digitalization and primary care enhancement. The critical burden brought by the pandemic upon hospital care mean these investments could no longer be delayed, considering the extraordinary backlogs of many treatments and the ordinary gaps of fragmented long-term care, in Italy and abroad. National guidelines have been published to standardize interventions across the Italian regions, and telemedicine is frequently mentioned as a key innovation to achieve both goals. The professional resources needed to run the facilities introduced in primary care are defined with great precision, but no details are given on how digitalization and remote care technologies must be implemented in this context. Building on this policy case, this paper focuses on what contribution digitalization and telemedicine can offer to specific primary care innovations, drawing from implemented technology-driven policies which may support the effective stratification, prevention and management of chronic patient needs, including anticipatory healthcare, population health management, adjusted clinical groups, chronic care management, quality and outcomes frameworks, patient-reported outcomes and patient-reported experience. All these policies can benefit significantly from digitalization and remote care technology, provided that some risks and limitations are considered by design.

    在过去的十年中,机器学习应用于计算机辅助综合计划,在预测化学和反应信息学方面取得了令人印象深刻的发展。虽然这些发展中的许多都是在相对较小的情况下取得的,定制的数据集,为了大规模推进人工智能在该领域的作用,反应数据的报告必须有重大改进。目前,大多数公开可用的数据以非结构化格式报告,并且严重不平衡,这会影响可以成功训练的模型类型。从这个角度来看,我们分析了在化学和分子生物学方面取得了成功的几个数据管理和共享计划。我们讨论了促成其成功的几个因素,以及我们如何从这些案例研究中吸取教训并将其应用于反应数据。最后,我们聚焦开放反应数据库,并总结社区可以采取的关键行动,使反应数据更容易发现,可访问,可互操作,和可重复使用(FAIR),包括使用资助机构和出版商的授权。
    The past decade has seen a number of impressive developments in predictive chemistry and reaction informatics driven by machine learning applications to computer-aided synthesis planning. While many of these developments have been made even with relatively small, bespoke data sets, in order to advance the role of AI in the field at scale, there must be significant improvements in the reporting of reaction data. Currently, the majority of publicly available data is reported in an unstructured format and heavily imbalanced toward high-yielding reactions, which influences the types of models that can be successfully trained. In this Perspective, we analyze several data curation and sharing initiatives that have seen success in chemistry and molecular biology. We discuss several factors that have contributed to their success and how we can take lessons from these case studies and apply them to reaction data. Finally, we spotlight the Open Reaction Database and summarize key actions the community can take toward making reaction data more findable, accessible, interoperable, and reusable (FAIR), including the use of mandates from funding agencies and publishers.

    护理和信息学在使用领域的结构化表示方面具有共同的优势,特别是“事物”的基本概念(即,概念,constructs,或命名实体)以及这些事物之间的关系。以机器可解释的格式准确表示护理知识是利用当代技术的必要下一步。在本体论中表达有效的护理理论,特别是形式本体论,不仅是护理服务,还有其他领域的调查员,临床信息系统开发人员,以及人工智能等先进技术的用户,这些技术寻求从护士和其他人产生的现实世界数据和证据中学习。这些努力将能够在护理和生成领域分享关于现象的知识和概念化,测试,修改,并在利用当代技术时提供基于理论的观点。护理处于这项工作的有利位置,利用护士信息学家之间的有意和有针对性的合作,科学家,和理论家。
    Nursing and informatics share a common strength in their use of structured representations of domains, specifically the underlying notion of \'things\' (ie, concepts, constructs, or named entities) and the relationships among those things. Accurate representation of nursing knowledge in machine-interpretable formats is a necessary next step for leveraging contemporary technologies. Expressing validated nursing theories in ontologies, and in particular formal ontologies, would serve not only nursing, but also investigators from other domains, clinical information system developers, and the users of advanced technologies such as artificial intelligence that seek to learn from the real-world data and evidence generated by nurses and others. Such efforts will enable sharing knowledge and conceptualizations about phenomena across the domains of nursing and generating, testing, revising, and providing theoretically-based perspectives when leveraging contemporary technologies. Nursing is well situated for this work, leveraging intentional and focused collaborations among nurse informaticists, scientists, and theorists.
