  • 文章类型: Review
    目标:Dissemination-implementation.org概述了110个理论,模型,和框架(TMF):我们对83个TMF进行了引文分析,搜索WebofScience和PubMed数据库。
    方法:搜索词广泛,包括“老化,\"\"较老,\"\"老年人\"和\"老年人。“我们提取了每个TMF从成立到2022年1月28日的识别文章中的内容。纳入的文章必须在与美国老年人直接相关的研究或质量改进工作中使用了TMF。
    结果:我们回顾了2,677篇文章,其中295篇文章引用了56种理论中的至少一种,模型,和框架(TMF)。五个TMF占引文的50%:到达,有效性,收养,实施,和维护(RE-AIM)1.0,实施研究综合框架(CFIR),服务组织创新的Greenhalgh扩散,质量增强研究倡议(QUERI)基于社区的参与式研究(CBPR)和促进卫生服务研究实施的行动(PARIHS)。TMF的应用各不相同,随着时间的推移,TMF的引文稳步增加,2020-2021年引文增加2-3倍。我们发现,只有41%的TMF使用是有意义的。
    结论:我们的结果表明,老化研究中的TMF利用率正在增加,但是需要更有意义地利用TMF。随着老年人人口的持续增长,对有效的循证实践和护理模式的需求将越来越大,以快速有效地转化为常规护理。TMF的使用对于建立此类证据以及识别和评估支持此翻译的方法至关重要。
    Dissemination-implementation.org outlines 110 theories, models, and frameworks (TMFs): we conducted a citation analysis on 83 TMFs, searching Web of Science and PubMed databases.
    Search terms were broad and included \"aging,\" \"older,\" \"elderly,\" and \"geriatric.\" We extracted each TMF in identified articles from inception through January 28, 2022. Included articles must have used a TMF in research or quality improvement work directly linked to older adults within the United States.
    We reviewed 2,681 articles of which 295 articles cited at least one of 56 TMFs. Five TMFs represented 50% of the citations: Reach, Effectiveness, Adoption, Implementation, and Maintenance 1.0, Consolidated Framework for Implementation Research, Greenhalgh Diffusion of Innovation in Service Organizations, Quality Enhancement Research Initiative, Community-Based Participatory Research, and Promoting Action on Research Implementation in Health Services. TMF application varied and there was a steady increase in TMF citations over time, with a 2- to 3-fold increase in citations in 2020-2021. We identified that only 41% of TMF use was meaningful.
    Our results suggest TMF utilization is increasing in aging research, but there is a need to more meaningful utilize TMFs. As the population of older adults continues to grow, there will be increasing demand for effective evidence-based practices and models of care to be quickly and effectively translated into routine care. Use of TMFs is critical to building such evidence and to identifying and evaluating methods to support this translation.

  • 文章类型: Systematic Review
    目的:本系统综述旨在确定引文分析的特点和在评估理由中的应用。设计,并将临床健康研究的研究结果置于早期类似研究的背景下。
    方法:我们搜索了MEDLINE(Ovid),Embase(Ovid),以及用于荟萃研究的Cochrane方法论注册。我们纳入了元研究研究,评估研究人员是否使用了早期的类似研究和/或对此类研究的系统评价,以告知新研究的理由或设计。研究人员是否使用系统评价来解释新结果,和荟萃研究评估冗余研究是否在特定领域发表。结果作为叙事综合呈现。
    结果:共纳入27项研究。引文分析的作者如何定义他们的结果似乎相当随意,以及如何参考具有里程碑意义的审查或遵守报告准则的预期将有助于启动,理由,设计,或相关临床试验的背景。
    结论:需要继续和改进促进循证研究的努力,在元研究研究中包括明确定义和合理的结果,以监测基于证据的方法的实施。
    This systematic review aimed to identify the characteristics and application of citation analyses in evaluating the justification, design, and placement of the research results of clinical health studies in the context of earlier similar studies.
    We searched MEDLINE (Ovid), Embase (Ovid), and the Cochrane Methodology Register for meta-research studies. We included meta-research studies assessing whether researchers used earlier similar studies and/or systematic reviews of such studies to inform the justification or design of a new study, whether researchers used systematic reviews to inform the interpretation of new results, and meta-research studies assessing whether redundant studies were published within a specific area. The results are presented as a narrative synthesis.
    A total of 27 studies were included. How authors of citation analyses define their outcomes appears rather arbitrary, as does how the reference of a landmark review or adherence to reporting guidelines was expected to contribute to the initiation, justification, design, or contextualization of relevant clinical trials.
    Continued and improved efforts to promote evidence-based research are needed, including clearly defined and justified outcomes in meta-research studies to monitor the implementation of an evidence-based approach.

    在线和虚拟教学一直是大多数教育机构从新冠肺炎创造的迫切需求中采用的灵丹妙药。我们提供了涵盖1991年至2021年的关于高等教育虚拟实验室的9523种出版物的全面文献计量研究。有影响力的文献计量学,如出版物和引文,有生产力的国家,捐助机构,资助者,期刊,作者,使用科学程序和系统文献审查原理(SPAR-4-SLR)协议研究了书目耦合。引入了一种新的指标来补充引文,称为场加权引文影响,该指标考虑了跨学科研究行为的差异。研究结果表明,72%的研究工作是在2011年至2021年之间发表的,很可能是由于数字化。2020-2021年的出版物数量最多,强调了大流行的影响。捐款最多的机构来自西班牙发达经济体,德国,和美国。与国际合著者的出版物的引用影响是最高的,强调与不同国家共同撰写论文的重要性。第一次,尽管在引用和Altmetrics注意力得分之间观察到非常低的相关性,但在虚拟实验室的背景下研究了Altmetrics。尽管如此,关注出版物的总体百分比呈线性增长。我们的工作还强调,虚拟实验室可以在实现联合国可持续发展目标方面发挥重要作用。特别是SDG4-质量教育,这在很大程度上仍然没有得到解决。
    Online and virtual teaching-learning has been a panacea that most educational institutions adopted from the dire need created by COVID-19. We provide a comprehensive bibliometric study of 9523 publications on virtual laboratories in higher education covering the years 1991 to 2021. Influential bibliometrics such as publications and citations, productive countries, contributing institutions, funders, journals, authors, and bibliographic couplings were studied using the Scientific Procedures and Rationales for Systematic Literature Reviews (SPAR-4-SLR) protocol. A new metric to complement citations called Field Weighted Citation Impact was introduced that considers the differences in research behavior across disciplines. Findings show that 72% of the research work was published between 2011-and 2021, most likely due to digitalization, with the highest number of publications in 2020-2021 highlighting the impact of the pandemic. Top contributing institutions were from the developed economies of Spain, Germany, and the United States. The citation impact from publications with international co-authors is the highest, highlighting the importance of co-authoring papers with different countries. For the first time, Altmetrics in the context of virtual labs were studied though a very low correlation was observed between citations and Altmetrics Attention Score. Still, the overall percentage of publications with attention showed linear growth. Our work also highlights that virtual laboratory could play a significant role in achieving the United Nations Sustainable Development Goals, specifically SDG4-Quality Education, which largely remains under-addressed.

    背景:Tivozanib(Fotivda)是一种抗血管生成酪氨酸激酶抑制剂,被食品和药物管理局(FDA)拒绝进入美国市场。相比之下,它被欧洲药品管理局(EMA)批准用于治疗成人肾细胞癌.鉴于这些监管机构的决定相互矛盾,以下研究的目的是(i)批判性地审查支持tivozanib批准的证据;(ii)通过引文分析来分析这些证据在文献中的传播.
    方法:Pivotal试验由两名独立的评论者使用Medline进行搜索,科克伦图书馆,ClinicalTrials.gov和欧洲公共评估报告。然后对每个试验的偏倚风险进行归纳评估。引用这些试验的文章是使用WebofSciences鉴定的。最后,引文的质量由两名独立评审员根据标准数据提取方法进行评估.
    结果:对主要证据的搜索确定了两项关键研究:FDA和EMA决定所基于的TIVO-1,TIVO-3是在机构的决定发布后进行的。TIVO-1试验提出了几个限制,损害了因果推断,关于(I)设计(没有盲化,不合适的比较器,和单向交叉),(ii)主要终点结果的内部一致性差,(iii)观察到的无进展生存期的获益(HR:0.80,95%CI[0.64-0.99])与总生存期无差异(HR:1.25,95%CI[0.95-1.62])之间存在差异。我们的引文搜索协议确定了在TIVO-1发表后的7年内引用了229篇文章,其中151篇(65.9%)引用讨论疗效的文章。在这151篇引用的文章中,有64篇(42.4%)发现了自旋的存在,39篇(25.8%)额外文章引用了结果,但没有提供足够的元素来解释TIVO-1结果。
    结论:EMA的批准是基于一项具有关键局限性的关键试验,使试验结果可能不确定。TIVO-1结果在科学文献中的广泛传播可能受到自旋的影响,或者结果以不充分的批评方式呈现。
    BACKGROUND: Tivozanib (Fotivda) is an anti-angiogenic tyrosine kinase inhibitor that was denied access to the US market by the Food and Drug Administration (FDA). In contrast, it was granted approval by the European Medicines Agency (EMA) for the treatment of Renal Cell Carcinoma in adults. Given the conflicting decisions from these regulatory agencies, the objectives of the following study are (i) to critically review the evidence supporting the approval of tivozanib; (ii) to analyse the dissemination of this evidence in the literature by way of a citation analysis.
    METHODS: Pivotal trials were searched by two independent reviewers using Medline, Cochrane Library, ClinicalTrials.gov and the European Public Assessment Report. The risk of bias for each trial was then inductively assessed. Articles citing any of these trials were identified using Web of Sciences. Finally, the quality of the citations was evaluated by two independent reviewers according to standard data extraction methods.
    RESULTS: The search for primary evidence identified two pivotal studies: TIVO-1 upon which the FDA and the EMA decisions were based, and TIVO-3 which was conducted after the agencies\' decisions had been issued. The TIVO-1 trial presented several limitations that compromised causal inference, in relation to (i) design (absence of blinding, inappropriate comparator, and one-way crossover), (ii) poor internal consistency in the results for the primary endpoint, (iii) a discrepancy between a benefit observed for progression-free survival (HR: 0.80, 95% CI [0.64-0.99]) and the absence of difference for overall survival (HR: 1.25, 95% CI [0.95 - 1.62]). Our citation search protocol identified 229 articles that cited TIVO-1 in the 7 years following its publication, among which 151 (65.9%) citing articles discussing efficacy. Presence of spin was identified in 64 (42.4%) of these 151 citing articles, and 39 (25.8%) additional articles citing results without providing enough elements to interpret the TIVO-1 results.
    CONCLUSIONS: EMA\'s approval was based on a single pivotal trial presenting critical limitations, rendering the results from the trial potentially inconclusive. The broad dissemination of TIVO-1 results in the scientific literature may have been affected by spin or results were presented in an inadequate critical manner.

    Peer-review of manuscripts submitted to scholarly journals for publication dates back ~ 350 years and this process represents the foundation of scientific publishing. After a manuscript has undergone and survived a rigorous peer-review, this conveys a stamp of approval, because it signifies the work has been checked by independent experts in the scientific discipline concerned. The publication and citation track records of people instructed to appear as expert witness in civil and criminal litigation are important considerations. Using a publically available database, the most highly cited scientists in the discipline legal and forensic medicine were identified. For each scientist, a composite score was calculated based on six different citation metrics; (i) Total number of citations, (ii) H-index, (iii) Hm-index, which modifies the H-index for multi-authored papers, (iv) Citations to single-author papers, (v) Citations to single and first author papers and (vi) citations to single, first and last author papers. The top 100,000 most highly cited scientists from all disciplines were identified along with the top 2% of the most highly cited in each of 176 sub-fields. The latest version of the citation databases, up to the end of 2020, classified 14.163 people as having legal and forensic medicine as their primary research discipline. Of these, there were 29 names listed among the top 100,000 most highly cited in all disciplines and 299 were among the top cited 2% in their particular sub-field. More than 50% of the highly cited forensic practitioners resided in four countries (USA, Germany, UK and Australia). The top-ten most highly cited individuals were the same in all four versions of the database (2017, 2018, 2019 and 2020) and represented the sub-disciplines of toxicology (n = 3), genetics/DNA/heredity (n = 3), whereas two specialized in pathology/toxicology and two in pathology/genetics.

    由于缺乏标准治疗,瘢痕疙瘩对临床医生来说仍然很麻烦。潜在的机制仍不清楚。文献计量分析可能是全面审查研究趋势的有力工具,评估出版物的性能,并提供未来的观点。没有针对瘢痕疙瘩研究的文献计量学分析。
    从1990年到2019年的出版物在WebofScienceCoreCollection中搜索了瘢痕疙瘩相关出版物。提供了文件类型的文献计量数据,年度出版物编号,最有生产力的期刊,出版地理,顶级潜在作者,被高度引用的文章。分析了单词在文章标题中的分布情况,评价了文章的主要研究热点,并确定了其发展趋势。进一步进行词聚类分析以检测瘢痕疙瘩研究中的新兴趋势。
    年度文章数量从1990年的24篇增加到2006年的63篇,然后急剧增加,2019年达到139。皮肤外科发表的文章数量最多,其次是整形和重建外科。美国以六项出版指标排名第一,中国自2012年以来的年度文章数量急剧增加。最近的研究热点包括潜在的致病机制,瘢痕疙瘩治疗,和治疗效果评价。
    瘢痕疙瘩仍是研究热点。将不断努力了解瘢痕疙瘩形成的潜在机制。尽管有许多治疗方式,瘢痕疙瘩治疗没有黄金标准,在探索新疗法方面正在做出许多努力。此外,可以预见,客观测量工具在瘢痕疙瘩和疤痕的评估中将具有更高的地位。
    UNASSIGNED: Keloids remain troublesome for clinicians because of the lack of standard therapy, and the underlying mechanisms are still unclear. Bibliometric analysis could be a powerful tool to comprehensively review research trends, evaluate publication performances and provide future perspectives. There is no bibliometric analysis focusing on keloid research.
    UNASSIGNED: Keloid related publications were searched in Web of Science Core Collection from the publication year 1990 to 2019. Bibliometric data were provided on document type, annual publication number, most productive journals, publication geography, top potential authors, and highly cited articles. The distribution of single words in article titles was analyzed to evaluate the main research focuses and determine their development trends. Word cluster analysis was further performed to detect emerging trends in keloid research.
    UNASSIGNED: The number of annual articles increased from 24 in 1990 to 63 in 2006 and then increased sharply, reaching 139 in 2019. Dermatologic Surgery published the highest number of articles followed by Plastic and Reconstructive Surgery. The USA ranked top with six publication indicators and China had a dramatic increase in the annual number of articles since 2012. Recent research hotspots include underlying pathogenetic mechanisms, keloid treatment, and therapeutic effect evaluation.
    UNASSIGNED: Keloids remain a research focus. Efforts will be continuously made to understand the underlying mechanism of keloid formation. Despite many treatment modalities, there is no gold standard for keloid treatment, and many efforts are being made in the exploration of new therapies. Moreover, it is foreseeable that objective measurement tools will have a higher status in the assessment of keloids and scars.

    The lateral lumbar interbody fusion technique for lumbar arthrodesis is gaining popularity and being added as an option to traditional posterior and anterior approaches. In light of this, we analyzed the literature to identify the 25 most cited articles regarding lateral lumbar interbody fusion. The Thomson Reuters Web of Science was systematically searched to identify papers pertaining to lateral lumbar interbody fusion. The results were sorted in order to identify the top cited 25 articles. Statistical analysis was applied to determine metrics of interest, and observational studies were further classified. A search of all databases in the Thomson Reuters Web of Science identified 379 articles pertaining to lateral lumbar interbody fusion, with a total of 3800 citations. Of the 25 most cited articles, all were case series, reporting on a total of 2981 patients. These 25 articles were cited 2232 times in the literature and total citations per article ranged from 29 to 433. The oldest article was published in 2006, whereas the most recent article was published in 2015. The most cited article, by Ozgar et al., was cited 433 times, and the journal Spine published 7 of the 25 most cited articles. Herein, we report and analyze the 25 most cited articles on lateral lumbar interbody fusion, which include 25 cases series reporting a variety of data on a total of 2513 patients. Such data might assist in the design and interpretation of future studies pertaining to this topic.
