      BACKGROUND: With the emergence of social media platforms, new bibliometric profiles measuring impact and exposure of scientific research online have been introduced as an alternative to traditional bibliometric outcomes. The objective of this article is to evaluate relationships between Altmetric scores, journal impact factor, and citation counts among the surgical literature.METHODS: We analyzed the top 10 highest cited articles for the 10 general surgery journals with the highest impact factors for 2013 and 2016 by noting citation counts and Altmetric scores for each article. We also identified the journal impact factor and age of journal associated Twitter accounts. Variables were assessed for correlation using Pearson's correlation testing via Microsoft Excel.
    RESULTS: A total of 240 articles were analyzed. For 2013, Altmetrics score analysis demonstrated a significant, positive correlation with citation number (r = 0.462, P < 0.0001) and journal impact factor (r = 0.439, P < 0.0001). The 2016 cohort also demonstrated significant, positive correlations between Altmetric scores and citation count after the removal of one outlier (r = 0.182, P = 0.047) and journal impact factor when considering all articles (r = 0.425, P < 0.0001). From 2013 to 2016, the total number of citations for all articles decreased from 11,027 to 7661, but cumulative Altmetric scores increased from 1078 to 4782. Age of creation for a journal's Twitter account did not significantly affect Altmetric score or traditional bibliometric measures in either 2013 (r = 0.370, P = 0.293) or 2016 (r = 0.441, P = 0.202).
    CONCLUSIONS: Altmetric scores, while significantly associated with citation count in the surgical literature, should not necessarily be used as a surrogate marker for evaluating research performance, impact, or exposure. It is possible, however, that as the use of social media for distributing and sharing scientific research continues to expand, that exposure on such platforms could impact future interest or studies.

      BACKGROUND: Randomised controlled trials (RCTs) provide the most reliable information to inform clinical practice and patient care. We aimed to map global clinical research publication activity through RCT-related articles in high-impact-factor medical journals over the past five decades.METHODS: We conducted a cross-sectional analysis of articles published in the highest ranked medical journals with an impact factor > 10 (according to Journal Citation Reports published in 2017). We searched PubMed/MEDLINE (from inception to December 31, 2017) for all RCT-related articles (e.g. primary RCTs, secondary analyses and methodology papers) published in high-impact-factor medical journals. For each included article, raw metadata were abstracted from the Web of Science. A process of standardization was conducted to unify the different terms and grammatical variants and to remove typographical, transcription and/or indexing errors. Descriptive analyses were conducted (including the number of articles, citations, most prolific authors, countries, journals, funding sources and keywords). Network analyses of collaborations between countries and co-words are presented.
    RESULTS: We included 39,305 articles (for the period 1965-2017) published in forty journals. The Lancet (n = 3593; 9.1%), the Journal of Clinical Oncology (n = 3343; 8.5%) and The New England Journal of Medicine (n = 3275 articles; 8.3%) published the largest number of RCTs. A total of 154 countries were involved in the production of articles. The global productivity ranking was led by the United States (n = 18,393 articles), followed by the United Kingdom (n = 8028 articles), Canada (n = 4548 articles) and Germany (n = 4415 articles). Seventeen authors who had published 100 or more articles were identified; the most prolific authors were affiliated with Duke University (United States), Harvard University (United States) and McMaster University (Canada). The main funding institutions were the National Institutes of Health (United States), Hoffmann-La Roche (Switzerland), Pfizer (United States), Merck Sharp & Dohme (United States) and Novartis (Switzerland). The 100 most cited RCTs were published in nine journals, led by The New England Journal of Medicine (n = 78 articles), The Lancet (n = 9 articles) and JAMA (n = 7 articles). These landmark contributions focused on novel methodological approaches (e.g. the "Bland-Altman method") and trials on the management of chronic conditions (e.g. diabetes control, hormone replacement therapy in postmenopausal women, multiple therapies for diverse cancers, cardiovascular therapies such as lipid-lowering statins, antihypertensive medications, and antiplatelet and antithrombotic therapy).
    CONCLUSIONS: Our analysis identified authors, countries, funding institutions, landmark contributions and high-impact-factor medical journals publishing RCTs. Over the last 50 years, publication production in leading medical journals has increased, with Western countries leading in research but with low- and middle-income countries showing very limited representation.

      BACKGROUND: Bibliometric analysis highlights the key topics and research trends which have shaped the understanding and management of a concerned disease. The objective of this study was to identify and characterize the most-cited articles on oral lichen planus (OLP), and highlight the analysis of key topics and research trends.METHODS: A comprehensive search was performed and identified in the Scopus database from 1907 to 5 March 2019 for the top-100 most-cited articles on OLP.
    RESULTS: The number of citations of the 100 selected articles varied from 101 to 570, with a mean of 178.7 citations per article. Malignant potential, immunopathogenesis, and topical drug therapy were the top-3 study topics, and the majority of high-quality articles were the research of the 3 topics. Journal of Oral Pathology and Medicine (n = 19) and Oral Surgery Oral Medicine Oral Pathology Oral Radiology (n = 14) were 2 journals with the most articles published. Both van der Waal I. and Scully C. were the most frequently contributing authors (n = 9). United States (n = 27) and Academic Centre for Dentistry Amsterdam (n = 7) was the most contributing country and institution, respectively. Systematic reviews (n = 2), randomized controlled trial (n = 1), cohort studies (n = 17) were study designs with higher evidence level, but the large majority (n = 80) were considered lower level.
    CONCLUSIONS: The results of this first citation analysis of the 100 most cited articles on OLP provide a historical perspective on scientific evolution, and suggest further research trends and clinical practice in the field of OLP.

      Background: To systematically analyze the global development trends and research focuses of shared decision-making (SDM) studies as a reference for researchers. Methods: We conducted a systematic search of the Web of Science (WoS) Core Collection on April 17, 2019, to retrieve studies related to SDM published from 2009 to 2018. VOSviewer (1.6.10), CiteSpace (5.4.R1) and Excel 2016 were used to analyze key features of SDM studies, including annual output, countries/regions, organizations, journals, authors, references, research hot-spots, and frontiers. Results: Up to April 17, 2019, a total of 6,629 studies on SDM were identified as published between 2009 and 2018. The United States participated in the most studies (n = 3,118), with the University of California-San Francisco ranking first (n = 183). Patient Education and Counseling [impact factor (IF) 2017 = 2.785] published the most studies (n = 257). Legare F participated in the most studies (n = 101), and the paper "Charles C, 1997, Soc Sci Med, V44, P681" occupied the highest co-citation (n = 657) position. The research hotspots and frontiers included "Informed consent," "Surgery," "Depression," "Older adult," and "Patient-centered care." Conclusion: The number of studies concerning SDM has continued to increase since 2009, with the United States leading the field. The landscape of the basis of SDM included mainly concept, practice framework and effect assessment of SDM. "Informed consent," "Surgery," "Depression," "Older adult," and "Patient-centered care" reflected the latest research focuses, and should receive more attention.

      In recent years, climate change and carbon sinks have been widely studied by the academic community, and relevant research results have emerged in abundance. In this paper, a scientometric analysis of 747 academic works published between 1991 and 2018 related to climate change and carbon sinks is presented to characterize the intellectual landscape by identifying and revealing the basic characteristics, research power, intellectual base, research topic evolution, and research hotspots in this field. The results show that ① the number of publications in this field has increased rapidly and the field has become increasingly interdisciplinary; ② the most productive authors and institutions in this subject area are in the USA, China, Canada, Australia, and European countries, and the cooperation between these researchers is closer than other researchers in the field; ③ 11 of the 747 papers analyzed in this study have played a key role in the evolution of the field; and ④ in this paper, we divide research hotspots into three decade-long phases (1991-1999, 2000-2010, and 2011-present). Drought problems have attracted more and more attention from scholars. In the end, given the current trend of the studies, we conclude a list of research potentials of climate change and carbon sinks in the future. This paper presents an in-depth analysis of climate change and carbon sink research to better understand the global trends and directions that have emerged in this field over the past 28 years, which can also provide reference for future research in this field.

      Background  Despite the number of female medical-school applicants reaching an all-time high and the increasing number of females in surgical training, males retain an overwhelming majority in senior surgical academic positions and formal leadership positions. This study aims to better understand the extent of and influences for gender disparity in general surgical societies throughout North America, Europe, and Oceania.  Methods  Data collection for this retrospective cross-sectional study took place between June and December 2017. Committee and subcommittee members from the eight selected general surgical societies that met the inclusion criteria (n = 311) were compiled into an Excel spreadsheet in which the data was recorded. Analyzed metrics included university academic ranking, surgical society leadership position, h-index, number of citations, and total publications. SCOPUS database (Elsevier, Amsterdam, Netherlands) was used to generate author metrics, and STATA version 14.0 (StataCorp, College Station, TX) was used for statistical analysis. Results Overall, 83.28% of members of the entities we studied were male and 16.72% were females. Males had significantly higher representation than females in all societies (Pearson chi2 = 29.081; p-value = 0.010). Females were underrepresented in all society leadership positions and university academic rankings. Male members had a higher median h-index, more number of citations, and more total publications. Conclusions The composition of the general surgical societies included in this study demonstrated significant gender disparity. Female inclusivity initiatives and policies must be initiated to promote greater research productivity and early career opportunities for female surgeons in the specialty of general surgery.

      BACKGROUND: Many researchers use the National Health Insurance Research Database (HIRD) to publish medical papers and gain exceptional outputs in academics. Whether they also obtain excellent citation metrics remains unclear.METHODS: We searched the PubMed database (http://www.ncbi.nlm.nih.gov/pubmed) using the terms Taiwan and HIRD. We then downloaded 1997 articles published from 2012 to 2016. An authorship-weighted scheme (AWS) was applied to compute coauthor partial contributions from the article bylines. Both modified x-index and author impact factor (AIF) proved complementary to Hirsch's h-index for calculating individual research achievements (IRA). The metrics from 4684 authors were collected for comparison. Three hundred eligible authors with higher x-indexes were located and displayed on Google Maps dashboards. Ten separate clusters were identified using social network analysis (SNA) to highlight the research teams. The bootstrapping method was used to examine the differences in metrics among author clusters. The Kano model was applied to classify author IRAs into 3 parts.
    RESULTS: The most productive author was Investigator#1 (Taichung City, Taiwan), who published 149 articles in 2015 and included 803 other members in his research teams. The Kano diagram results did not support his citation metrics beyond other clusters and individuals in IRAs.
    CONCLUSION: The AWS-based bibliometric metrics make individual weighted research evaluations possible and available for comparison. The study results of productive authors using HIRD did not support the view that higher citation metrics exist in specific disciplines.

      PURPOSE: To identify the 50 most frequently cited publications related to hip arthroscopy.METHODS: The Clarivate Analytics Web of Knowledge database was used to search for publications relating to hip arthroscopy. The top 50 most cited articles that met the inclusion criteria were recorded and reviewed for various metrics.
    RESULTS: The top 50 publications were cited a total of 8,306 times, with an average of 437.2 total citations per year. Of the 50 articles identified, 44 had been published since 2000. Case series, expert opinion articles, and review articles were the most common study types.
    CONCLUSIONS: The majority of the most influential articles on hip arthroscopy are case series and expert opinions; however, as hip arthroscopy continues to become more widely performed, higher-level articles should supplant some of the articles included in this analysis. As indications for hip arthroscopy have expanded, so has its body of literature, with the vast majority of articles identified in our study having been published since 2000. Elucidating the 50 most cited articles in hip arthroscopy will allow practicing physicians a quick reference to the highest-yield articles and will allow residency programs to guide their education on the topic.
    CLINICAL RELEVANCE: The top 50 list provides residents, fellows, and researchers with a comprehensive list of the major academic contributions to hip arthroscopy.

      The number of citations a publication receives has been regarded as one measure of its importance and clinical impact. However, studies have yet to investigate which characteristics are predictors of citation rates within the spine subspecialty literature. To explore this topic, all articles published in 2010 in Spine and from 2010 to 2011 in The Spine Journal and the Journal of Neurosurgery: Spine were reviewed. The Web of Science search engine was used to determine the number of times each article was cited in the 5 years following its publication. Sample characteristics were collected and were compared with a χ test for differences Multivariate logistic regression was utilized to determine if collected study characteristics were associated with achievement of citation frequency higher than the median for the entire study sample. Among the 927 articles analyzed, the 5-year citation number ranged from 0 to 125, with a median of 8 (interquartile range: 4-16). Upon multivariate analysis, the following were identified as predictors of citation number higher than the median: North American origin (P=0.014), sample size >30 (P<0.001), study topic (P<0.050), and publication in the Journal of Neurosurgery: Spine (P<0.001). Practitioners and research personnel can use these findings to help elucidate which factors might affect the potential impact and overall reach of their work in the spine literature.

      The purpose of this study is to determine the highest-cited articles on developmental dysplasia of the hip (DDH) and analyze their bibliometric characteristics. We searched the Web of Science (WoS) for articles with the highest number of citations on DDH and recorded their number of citations in WoS, Scopus, and Google Scholar (GS). We ranked and selected the top 100 cited articles. The average number of citations in WoS was 148 (range 66-638). The most-cited article in all databases was Crowe's total hip replacement cohort on DDH. The Journal of Bone and Joint Surgery American Volume (n = 35) had the most articles in the list, and the United States (n = 46) contributed with the most articles. The University of Bern had the most publications (n = 8). Most studies were therapeutic (n = 45) or diagnostic (n = 29). Hip preservation and arthroplasty investigations have had an increment in citations in recent decades. We provide an historical perspective on research conducted on DDH. A majority of the articles were observational and therapeutic. All databases had good correlation in the number of citations.

      INTRODUCTION: In 2015, with a stated goal of disseminating best teaching practices and developing a community of educational scholars, the Council of Emergency Medicine Directors (CORD) and the Clerkship Directors of Emergency Medicine (CDEM) created an annual Special Issue in Educational Research and Practice (Special Issue) in cooperation with the Western Journal of Emergency Medicine. The intention of this study was to analyze the impact of this effort to date.METHODS: Bibliometric data was gathered on all four special issues, 2015-2019, from the Web of Science and then verified with the eScholarship website. Authorship, academic affiliation, date published, article type, and format were tabulated for descriptive analysis. Using metrics from Google Scholar, alternative scholarly impact metrics (altmetrics), and the eScholarship website, the authors identified top articles and grouped them into themes.
    RESULTS: Of the 136 articles included in the first four years of the Special Issue, 126 represented peer-reviewed publications with an overall acceptance rate of 25.0% (126/505). Authors from this cohort represented 103 of the 182 (56.6%) Accreditation Council for Graduate Medical Education (ACGME) programs in existence at the time of the inaugural issue. Multi-institutional studies represented 34.9% (44/126) of the peer-reviewed publications. Traditional and alternative publication metrics are reported to assess the impact of articles from the Special Issues.
    CONCLUSION: The Special Issue is a proven outlet to share best practices, innovations, and research related to education. Additionally, the infrastructure of this process promotes the development of individual faculty and a community of teaching scholars.

      Ever-growing globalization and industrialization put forward impending requirements for green and sustainable logistics (G&SL). Over the past decades, G&SL initiatives triggered worldwide deliberations, aiming at easing negative transport externalities and improving supply chain performance. This review-based paper attempts to offer a joint quantitative and qualitative understanding for the overall evolutionary trend, knowledge structure, and literature gaps of the G&SL research field. Employing the science mapping approach, a total of 306 major paper published from 1999 to 2019 were retrieved, elaborated on, and synthesized. Visualized statistics regarding publication years, journal allocation/co-citation, inter-country/institution collaboration, influential articles, co-occurred keywords, and time view clusters of research themes were analyzed bibliographically. On this basis, a total of 50 sub-branches of G&SL knowledge were classified and thematically discussed based on five alignments, namely (i) social-environmental-economic research, (ii) planning, policy and management, (iii) application and practice, (iv) technology, and (v) operations research. Finally, the current knowledge obstacles and the future research opportunities were suggested. The findings contribute to portray a systematic intellectual prospect for the state quo, hotspots, and academic frontiers of G&SL research. Moreover, it provides researchers and practitioners with heuristic thoughts to govern transportation ecology and logistics service quality.

      PURPOSE: The purpose of this study was to analyze the projects submitted to the ITI International Team for Implantology for funding and the scientific publications ensuing from these projects, over a period of 30 years.MATERIALS AND METHODS: This analysis was performed based on information available in the database of the ITI. For each project, data related to institution, country of origin, and grant status (financed or rejected) were extracted. For the financed projects, the grant amount and number of publications were recorded. Publications were searched independently by two investigators. For all publications, the study topic, study design, and citation number were recorded.
    RESULTS: From a total of 1,372 submitted projects from 51 different countries and 308 different institutions, 514 (37.46%) were financed by the ITI. This amounts to more than CHF 52 million invested in favor of implant dentistry and related fields. A total of 552 publications (including original research and reviews) were identified related to these projects, with the majority being in vitro studies (n = 198), and the most common topic researched was implant surface modification (n = 134). The United States was the country and the University of Bern was the institution with the largest number of financed projects and published papers.
    CONCLUSION: This analysis revealed that the ITI has been actively supporting research in the field of implant dentistry and related areas globally. Several concepts in present-day implantology are based on literature from ITI-funded projects.

      INTRODUCTION: Forming effective networks is important for personal productivity and career development. Although critical for success, these networks are not well understood. The objective of this study was to usze a social network analysis tool to demonstrate the growth of institutional publication networks for education researchers and show how a single institution has expanded its publication network over time.METHODS: Publications from a single institution's medical education research group (MERG) were pulled since its inception in 2010 to 2019 using Web of Science to collect publication information. Using VOSViewer software, we formed and plotted a network sociogram comparing the first five years to the most recent 4.25 years to compare the institutions of authors from peer reviewed manuscripts published by this group.
    RESULTS: We found 104 peer-reviewed research articles, editorials, abstracts, and reviews for the MERG authors between 2010 and 2019 involving 134 unique institutions. During 2010-2014, there were 26 publications involving 56 institutions. From 2015-2019, there were 78 publications involving 116 unique institutions.
    CONCLUSION: This brief report correlates successful research productivity in medical education with the presence of increased inter-institutional collaborations as demonstrated by network sociograms. Programs to intentionally expand collaborative networks may prove to be an important element of facilitating successful careers in medical education scholarship.

      Construct: In this study, the authors investigated the validity of a quantitative measure of self-authorship among medical students. Self-authorship is a cognitive-structural theory incorporating the ability to define one's beliefs, identity, and social relations to operate in a complex, ambiguous environment.Background: Competency-based medical education (CBME) provides learners with the opportunity to self-direct their education at an appropriate pace to develop and exhibit required behaviors while incorporating functioning relationships with supervisors and trainers. Students must develop skills to adjust and succeed in this educational climate. Self-authorship is a theoretical lens that is relevant to identifying the development of the skills necessary to succeed in a CBME curriculum. Understanding the level of attained self-authorship by medical students can provide important information about which professional characteristics are more prevalent among those who are more self-authored and about how students succeed in medical school. Although there are calls in the extant literature for the application of self-authorship in medical education, there is no quantitative measure to assess its development among medical students.
    Approach: The authors developed a survey to measure self-authorship, including a free text question regarding the thought process around a hypothetical ethical situation during training. Data were collected in 2014 and 2015 from undergraduate medical students and analyzed using factor analysis and qualitative analysis of the free text. Validity evidence was sought regarding content, internal structure, and relationships to other variables.
    Results: Analysis supports the use of a 22-item instrument to assess 3 constructs of self-authorship: asserting independence and autonomy, knowledge processing, and sense of self in ethical situations. Content analysis of text responses supported the ability of the instrument to separate development, or a lack thereof, of self-authorship.
    Conclusions: The authors identified an instrument that measures multidimensional, higher-order characteristics that intersect with self-authorship. This instrument can be useful at a macro level for curricular and student assessment of self-authorship. Development of these characteristics can help foster success in a CBME environment and support curricular efforts in this regard. Understanding a student's level of self-authorship can help identify areas for support as well as allow for comparisons of different student characteristics.

      Contemporary inquiries in psychology and law increasingly cross disciplinary boundaries for inspiration. Our focus is on whether such research is substantive in both directions and whether interdisciplinary psychology-and-law author teams produce more meaningful interdisciplinary work, specifically in decision-making research conducted between 2004 and 2017. We found that interdisciplinary psychology-and-law author teams (a) produce publications that show more cross-disciplinary integration in methods than single-discipline teams, (b) produce publications with more conceptual integration in the introduction and discussion than only law author teams, and (c) elicit more citations than only law or only psychology author teams. When considering a collaborative team approach, we suggest that the disciplinary background of the collaborators is a meaningful indicator of the type of interdisciplinary research to be conducted. We also suggest that it would be beneficial for both psychology and law journals to be more open to publishing scholarship from mixed disciplinary teams.

      JIB.tools 2.0 is a new approach to more closely embed the curation process in the publication process. This website hosts the tools, software applications, databases and workflow systems published in the Journal of Integrative Bioinformatics (JIB). As soon as a new tool-related publication is published in JIB, the tool is posted to JIB.tools and can afterwards be easily transferred to bio.tools, a large information repository of software tools, databases and services for bioinformatics and the life sciences. In this way, an easily-accessible list of tools is provided which were published in JIB a well as status information regarding the underlying service. With newer registries like bio.tools providing these information on a bigger scale, JIB.tools 2.0 closes the gap between journal publications and registry publication. (Reference: https://jib.tools).

      OBJECTIVES: To analyze the proportion of gastroenterology society guidelines and technical reviews with female authors.METHODS: Retrospective study of the sex of authors of American Association for the Study of Liver Disease (AASLD), American College of Gastroenterology (ACG) and American Gastroenterological Association (AGA) guidelines and technical reviews.
    RESULTS: Between 2007 and 2019, 21% of authors of AASLD, ACG and AGA guidelines, and technical reviews were female. Eighteen percent of first authors were female. There was a statistically significant increase in female authorship over the past 10 years only for AASLD guidelines.
    CONCLUSIONS: There were fewer female authors of AASLD, ACG and AGA guidelines, and technical reviews than males. This disparity decreased over time only in AASLD guidelines. Addressing disparities in guideline and technical review authorship may promote academic advancement for female gastroenterologists.

      BACKGROUND: Around the world in tropical areas, certain vector-borne diseases have become endemic and hyperendemic. Among the developing nations, there are common difficulties in establishing the incidences of various diseases, especially vector-borne diseases with complex etiologies and a broad spectrum of presentations. One alternative approach to characterization of the disease outbreaks examines the possibilities of developing proxy information from online news articles. Such sources are being evaluated for applications to disease surveillance, early outbreak detection, and epidemiology research. Our study here looks to examine the potential of news articles in elucidating outbreaks of dengue in India and zika disease in Brazil.OBJECTIVE: This study is designed to assess the potential usefulness of news articles in tracking case numbers of dengue and zika through an improved understanding of how news outlets report on disease. We specifically examine the possibilities of providing near real-time reporting on the development of outbreaks of dengue and zika.
    METHODS: Newspaper articles related to dengue fever and zika disease in India and Brazil, respectively were extracted from the LexisNexis database. We targeted news articles available from five popular international news sources and two local newspapers in each country. The news articles were processed to provide yearly and weekly time series in the number of articles concerned with dengue and zika to test their potential suitability as proxies for disease prevalence. The collections of articles were analyzed using a text mining tool-kit that subdivides a collections of news articles into smaller clusters to study the topical focus of articles and their relevance to tracking diseases.
    RESULTS: For dengue fever in India, the local newspapers provide a better source of information than international newspapers. The multi-year analysis (2010-2016) suggests that the numbers of dengue cases are strongly correlated with the numbers of news reports, with an R2 value of 0.88. For zika disease in Brazil, the news reports provided useful information on the timing of the zika outbreak. Reporting increase sharply at the beginning of 2016, peaked in weeks 5 to 8, and decreased sharply. The numbers of articles remained low for the remainder of 2016 and 2017. Comparisons with reported case again show article numbers to be a useful proxy of prevalence of zika in Brazil.
    CONCLUSIONS: The paper describes a strategy that applies newspaper as proxies to monitor outbreaks of infectious diseases and to study the epidemiology. It has potential applicability in some developing countries and regions with relatively poor medical infrastructures and records. Clearly, large national newspapers in India provide a better source of information on diseases than international outlets. This approach has potential with selected diseases in a few selected countries. Article numbers internationally appear to vary in proportion to the perceived health impact.
