    The State of Music Therapy Studies in the Past 20 Years: A Bibliometric Analysis.
    Kailimi Li, Linman Weng, Xueqiang Wang.
      Purpose: Music therapy is increasingly being used to address physical, emotional, cognitive, and social needs of individuals. However, publications on the global trends of music therapy using bibliometric analysis are rare. The study aimed to use the CiteSpace software to provide global scientific research about music therapy from 2000 to 2019. Methods: Publications between 2000 and 2019 related to music therapy were searched from the Web of Science (WoS) database. The CiteSpace V software was used to perform co-citation analysis about authors, and visualize the collaborations between countries or regions into a network map. Linear regression was applied to analyze the overall publication trend. Results: In this study, a total of 1,004 studies met the inclusion criteria. These works were written by 2,531 authors from 1,219 institutions. The results revealed that music therapy publications had significant growth over time because the linear regression results revealed that the percentages had a notable increase from 2000 to 2019 (t = 14.621, P < 0.001). The United States had the largest number of published studies (362 publications), along with the following outputs: citations on WoS (5,752), citations per study (15.89), and a high H-index value (37). The three keywords "efficacy," "health," and "older adults," emphasized the research trends in terms of the strongest citation bursts. Conclusions: The overall trend in music therapy is positive. The findings provide useful information for music therapy researchers to identify new directions related to collaborators, popular issues, and research frontiers. The development prospects of music therapy could be expected, and future scholars could pay attention to the clinical significance of music therapy to improve the quality of life of people.

    A Bibliometric Analysis and Visualization of the Top-Cited Publications in Mild Traumatic Brain Injury.
    Jian Shi, Xianping Du, María José Cavagnaro, Na Li.
      Background: For measuring their impact in scientific research, the citation count of the publications is used in the bibliometric analysis, though still in the bibliometric analysis, there is no comprehensive summary of mild traumatic brain injury (mTBI) research. This article intends to provide the physicians and the neuroscientists with a reference guide to assess the most influential publications written on this subject through a macroscopic view of the research activities on mTBI. Methods: The database of the Web of Science was used to compile the 100 top-ranking publications on mTBI. The selected publications were evaluated on the basis of the several categorizations including the type of the publications, number of citations, country of origin, and year of publication. Results: Between 1946 and 2020, the 13,040 publications that were published were included in the database. The least cited publications received 274 citations, while the most cited received 1,748. Altogether, 71 publications were from the USA while 29 were from other countries. Among all the institutions, the University of Pittsburgh Medical Center led the list with six publications. Around 100 papers, mostly on the clinical studies in the categories of neurology and neurosciences, were published in 54 different journals. Conclusions: This study provides both a transverse section summary and historical retrospect for the clinical advances of mTBI, and the publications of important observations that contributed a significant impact on the treatment and prevention of mTBI had been identified.

    Runlin Yang, Yifan Ren, Julian Maingard, Vincent Thijs, Dustin Viet Anh Le, Hong Kuan Kok, Michael J Lee, Joshua A Hirsch, Ronil V Chandra, Duncan Mark Brooks, Hamed Asadi.
      BACKGROUND: The literature base for endovascular treatment of brain arteriovenous malformations (BAVMs) has grown exponentially in recent decades. Bibliometric analysis has been used to identify impactful articles in other medical specialties. The aim of this citation analysis was to identify and characterize the top 100 most cited articles in the field of endovascular BAVM treatment.METHODS: The top-cited papers were identified by searching selected keywords ("endovascular treatment," "interventional treatment," "brain arteriovenous malformation," "emboliz(s)ation") on the Web of Science platform. The top 100 articles were ranked according to their number of citations. Each article was further evaluated to obtain predefined characteristics including citation(s) per year, year of publication, authorship, journal-title and impact factor, article topics, article type, and level of evidence.
    RESULTS: The top 100 most cited articles for endovascular BAVM treatment were published between 1960 and 2014. The total number of citations for these articles ranged from 56 to 471 (median 85.5). Most articles (76%) were published between 1990 and 2009 in three journals (56%), originated in the USA (52%) followed by France (16%). The most common topic related to embolization agents and the majority of articles constituted level IV or V evidence.
    CONCLUSIONS: This study provides a comprehensive overview of the most cited articles in the field of endovascular BAVM treatment. Our analysis recognizes key contributions from authors and institutions in the field and leads to a better understanding of the evidentiary framework for BAVM treatment.

      AIM: The International Endodontic Journal (IEJ) has served as a platform for research and clinical practice in Endodontics since 1967. This study provides a bibliographic analysis and overview of the publications that have appeared in the IEJ from 1967-2020.METHODOLOGY: A literature search was performed in Elsevier's Scopus database to locate all the publications of the International Endodontic Journal. Various bibliometric software packages including the open-source visualization software Gephi and Biblioshiny (version 2.0) were employed for data visualisation and analysis.
    RESULTS: A total of 3739 records with citation and bibliographic details were selected and retrieved to allow a bibliometric analysis to be performed. The bibliometric analysis indicates that the IEJ has grown both in terms of productivity and influence. Over time, the journal has been associated with an increase in the number of manuscripts published and the citations they have attracted, but with minor downward fluctuations in citations in the last few years. Bibliographic coupling of the IEJ articles revealed that the major research themes published in the journal include "endodontics", "root canal treatment", "calcium hydroxide", "apical periodontitis", "mineral trioxide aggregate", "microbiology", "cyclic fatigue", "cone-beam computed tomography", and "micro-computed tomography". Authors affiliated to institutions in the UK were the major contributors to the journal and linked with other countries such as Brazil, United States, and Malaysia. The largest number of publications were from the University of São Paulo, Brazil.
    CONCLUSION: The IEJ is one of the leading journals in Endodontology and has been providing a platform for innovative research and clinical reports for more than 50 years. Publications have been associated with a wide range of authors, institutions, and countries around the world.

    Beatriz Tarazona-Álvarez, Andres López-Roldan, Antonio Vidal-Infer, Daniel López-Padilla, Adolfo Alonso-Arroyo.
      BACKGROUND: The exponential increase in implant placement worldwide and the high prevalence of its associated pathologies have prompted an increasing contribution by the scientific community to the number of publications related to peri-implant pathologies.PURPOSE: The objective of this work is to carry out a bibliometric analysis of scientific production on peri-implant diseases.
    MATERIALS AND METHODS: The search strategy included titles, keywords, and abstracts based on the term peri-implantitis and all the possible combinations existing in Science Citation Index Expanded (SCIE) of the main collection of Web of Science. Two limits were established: the document typology was limited to Article and Review, and articles published up to 2019 were selected. All articles were refined and standardized manually to avoid typographical errors and duplications in authors' names or institutions.
    RESULTS: The total number of papers collected was 2547. A significant increase was observed in the number of articles published, especially in the past 10 years. The three most productive authors were Europeans, and the 45 most productive institutions were the universities. The most productive funding entities were the governments. Of the published works, 42.28% were funded. Of the 2547 records, 86.53% presented keywords.
    CONCLUSIONS: Scientific literature on peri-implantitis shows scientific growth in recent years, with a growing trend towards collaboration between authors and institutions. Most of the works have been published in high-impact journals, and in the last 2 years, more than half of the works have received some type of public or private funding.

    Nicolas Vuillemin, Hans-Christoph Pape, Pol Maria Rommens, Kurt Lippuner, Klaus-Arno Siebenrock, Marius Johann Keel, Johannes Dominik Bastian.
      Background and Objectives: The population is aging and fragility fractures are a research topic of steadily growing importance. Therefore, a systematic bibliometric review was performed to identify the 50 most cited articles in the field of fragility fractures analyzing their qualities and characteristics. Materials and Methods: From the Core Collection database in the Thomson Reuters Web of Knowledge, the most influential original articles with reference to fragility fractures were identified in February 2021 using a multistep approach. Year of publication, total number of citations, average number of citations per year since year of publication, affiliation of first and senior author, geographic origin of study population, keywords, and level of evidence were of interest. Results: Articles were published in 26 different journals between 1997 and 2020. The number of total citations per article ranged from 12 to 129 citations. In the majority of publications, orthopedic surgeons and traumatologists (66%) accounted for the first authorship, articles mostly originated from Europe (58%) and the keyword mostly used was "hip fracture". In total, 38% of the articles were therapeutic studies level III followed by prognostic studies level I. Only two therapeutic studies with level I could be identified. Conclusions: This bibliometric review shows the growing interest in fragility fractures and raises awareness that more high quality and interdisciplinary studies are needed.

    Xinning Mi, Xiaoxiao Wang, Ning Yang, Yongzheng Han, Yue Li, Taotao Liu, Dengyang Han, Yi Yuan, Yiyun Cao, Chengmei Shi, Xiangyang Guo, Yang Zhou, Zhengqian Li.
      BACKGROUND: In line with aging populations and increased application of anesthesia and surgery, perioperative neurocognitive disorder (PND) has received growing attention worldwide. Considerable researches into PND are being conducted; however, the quantity and quality of such researches have not been reported. Through a retrospective bibliometric analysis, this study aims to identify and characterize the top 100 cited publications on PND.METHODS: We searched the Web of Science database to find the top 100 cited articles focusing on PND. We collected bibliographic information, including year of publication, country of origin, article type, published journal, citation count, and authorship. To determine changes with time, we compared older and newest articles.
    RESULTS: The top 100 cited articles were published between 1955 and 2016; the number of citations ranged from 111 to 1248. The United States had the most published papers; clinical trial was the most common article type. The specialty journals of Anesthesiology and Anesthesia & Analgesia were the two most cited journals. Newest articles had a comparable number of citations to older articles, but the former had higher annual citation rates, greater funding disclosures, more focus on basic research, and more open access publications.
    CONCLUSIONS: This study provides a comprehensive overview of the most cited articles and highlights the increasing attention on PND. High-quality clinical trials with a greater journal impact factor receive more citations. However, there has been a growth in the number of basic science studies as an area of research with respect to the pathogenesis of PND.

    Characterization of top 100 researches on e-waste based on bibliometric analysis.
    Xianghong Chen, Ming Liu, Bo Xie, Liwei Chen, Jingting Wei.
      With rapid development of energy, information, and communication technology, e-waste problem has become one of the global issues to be settled urgently. The main features on publication years, journals, countries and institutions, authors, keywords, and content types of the 100 most-cited articles on e-waste had been unfolded in this research. The direction and way forward were illustrated, the trends to date were demonstrated, and the terrain and pathways were evaluated on the research of e-waste. Bibliometric analysis method was applied to analyze various attributes on the 100 most-cited articles which were retrieved from WoSCC on May 25, 2021, by utilizing the software tools Microsoft Excel 2016 and VOS viewer 1.6.9. The publication year and citation number of the 100 articles ranged between 2003 and 2017 and from 83 to 925, respectively. Environmental Science & Technology (n=17) published the maximum articles. Waste Management, Journal of Hazardous Materials, and Environmental Science & Technology were the core journals on e-waste. One hundred twenty-three institutions and 25 countries were involved in publishing the 100 articles. Three hundred seventy authors contributed to the 100 articles in total. A total of 267 keywords occurred in the 100 articles. The keywords "e-waste" and "recycling" held the highest occurrences. The study content of the 100 articles could be classified into four types including the characteristic-and-property type, the environment-and-health type, the management-and-economic type, and the technique-and-processing type. Overall completeness and applicability of the evidence found in this study were verified sufficiently; the potential biases in the review process were also considered. The innovations of the research from the past bibliometric analysis work on e-waste were stated, and the implication for practice and research of this study were explained as well. 2007, 2008, and 2009 were a peak of the researches on e-waste, while the recent years were experiencing a valley. China and its institutions were most influential in this field on e-waste. India was becoming more and more influential on e-waste research in the world. Nigeria was the research center in Africa, and Brazil was the research center in Latin America. Wong Minghung was the most important expert on e-waste. The impact on environment and human being's health was the hot topic of researches on e-waste; the characteristic and property of e-waste were studied not enough. The researches of technique and processing would be the direction and way forward in the study field on e-waste. The characteristic and property on e-waste would need more attention to be researched. The researchers could develop new pathways based on and beyond the four types of content evaluated in this research.

      The aim of the paper is to provide an in-depth evaluation of the research output of yoga intervention on type 2 diabetes mellitus from 1975 to 2019 using large-scale data analysis, bibliometric indicators, and density equalizing mapping. Data related to yoga-diabetic research, as search descriptors were retrieved using the Scopus database. The most common bibliometric indicators were annual research output, total citations, productive countries and leading authors, journals and institutions, and frequently cited articles. The number of global research articles retrieved for yoga-diabetic research over the study period 1975-2019 was 411. The growth rate of global publications in 2015-2019 is four times as high as in 1975-2003. The total number of citations for the retrieved articles was 7189, and the average number of citations per article was 23.82. Of these journals, the Journal of Alternative and Complementary Medicine has published the highest number of papers, which accounts for 2.9% of total publications. This study showed a wide variety of journals in which yoga-diabetic articles are published; these bibliometric indicators provide useful information on performance assessment of productivity and quality of research output. Therefore, this study provides a helpful reference for endocrinologists, yoga therapists, policy decision-makers, and diabetes researchers.

    Yang Zhang, Lei Huang, Yongwei Wang, Yajia Lan, Yonggang Zhang.
      This study aimed to analyze the bibliometric characteristics of the publications on occupational stress and highlight key research topics and future trends. The Web of Science Core Collection database was searched to collect publications on occupational stress, from inception to December 9, 2020. Two authors independently screened eligible literature and extracted the data. Bibliometric analyses were performed using VOSviewer 1.6.6 and R 3.6.3 software. Overall, 6,564 publications on occupational stress were included. "Stress," with a total link strength of 1,252, appeared as the most co-occurrence keyword, followed by "occupational stress," "job stress," and "job satisfaction." All studies were published between 1956 and 2020. Among them, 6,176 (94.35%) papers were written in English, and 4,706 (70.25%) were original articles. The top three Web of Science categories were "public environmental occupational health" (n = 1,711), "psychology, applied" (n = 846), and "psychology, multidisciplinary" (n = 650). The 100 top-cited articles were mentioned a total of 36,145 times, with a median of 361, ranging from 174 to 5,574. The United States was the most productive country, with 1,780 publications. The main partners of the United States were England and China. Three themes of occupational stress research were identified: job satisfaction, burnout, and occupational stress-related health problems. This bibliometric analysis provides a comprehensive understanding of the trends and most influential contributions to the field of occupational stress, thus promoting ideas for future research.

    Srinivas B S Kambhampati, Nagashree Vasudeva, Raju Vaishya, Mohit Kumar Patralekh.
      BACKGROUND & AIMS: It has been just over a year since the Covid-19 pandemic started. The top 50 cited articles on this subject would help identify trends and focus on the research efforts.METHODS: We utilised e-utilities in PubMed to find publications on Covid-19 until the date of search on 7/2/21. The iCite website was used to find the top 50 citations of the output from the search strategy. We looked into their full text for the editorial dates, type of study, level of evidence, focus of the article and country of origin. We also counted the errata and comments on each of them.
    RESULTS: The total number of citations of all 50 articles was 123,960, the highest being 10, 754 for a single article. Huang C was the most cited first author. They were published from week 4-17, with February being the month with most citations. Lancet was the most cited journal, having published 9 of the 50 articles. Majority belonged to level 3 of the evidence ladder and were retrospective studies. Thirty percent of them had an errata published and an average of 7 comments per article.
    CONCLUSION: The top 50 most cited articles identify the most impactful studies on Covid-19, providing a resource to educators while identifying trends to guide research and publishing efforts. There has been an explosion of publications and an unprecedented rate and number of citations within the first year for any single condition in the literature.

    Bibliometric Evaluation of Global Tai Chi Research from 1980-2020.
    Yanwei You, Leizi Min, Meihua Tang, Yuquan Chen, Xindong Ma.
      While studies on the health benefits of Tai Chi have sprung up over the past four decades, few have engaged in collecting global data, estimating the developing trends, and conducting reviews from the perspective of visualization and bibliometric analysis. This study aimed to provide a summary of the global scientific outputs on Tai Chi research from 1980 to 2020, explore the frontiers, identify cooperation networks, track research trends and highlight emerging hotspots. Relevant publications were downloaded from the Web of Science Core Collection (WoSCC) database between 1980 and 2020. Bibliometric visualization and comparative analysis of authors, cited authors, journals, co-cited journals, institutions, countries, references, and keywords were systematically conducted using CiteSpace software. A total of 1078 publications satisfied the search criteria, and the trend of annual related publications was generally in an upward trend, although with some fluctuations. China (503) and Harvard University (74) were the most prolific country and institution, respectively. Most of the related researches were published in the journals with a focus on sport sciences, alternative medicine, geriatrics gerontology, and rehabilitation. Our results indicated that the current concerns and difficulties of Tai Chi research are "Intervention method", "Targeted therapy", "Applicable population", "Risk factors", and "Research quality". The frontiers and promising domains of Tai Chi exercise in the health science field are preventions and rehabilitations of "Fall risk", "Cardiorespiratory related disease", "Stroke", "Parkinson's disease", and "Depression", which should receive more attention in the future.

    Insight into the characteristics of research published in traditional, complementary, alternative, and integrative medicine journals: a bibliometric analysis.
    Jeremy Y Ng.
      BACKGROUND: Traditional, complementary, alternative and integrative medicine (TCAIM) can be described as diverse medical and healthcare interventions, practices, products, or disciplines that are not considered as part of conventional medicine. Inherent in its definition, TCAIMs are comprised of a wide variety of therapies with highly variable safety and effectiveness evidence profiles. Despite this, the use of many TCAIMs is highly prevalent among patients globally. The present study consists of a bibliometric analysis of TCAIM journals.METHODS: A single search of all International Standard Serial Number (ISSNs) of all journals categorized as "complementary and alternative medicine" (code 2707) based on the All Science Journal Classification (ASJC) was run on Scopus on April 17, 2021. All publication types were included; no further search limits were applied. The following bibliometric data were collected: number of publications (in total and per year), authors and journals; open access status; journals publishing the highest volume of literature and their impact factors; language, countries, institutional affiliations, and funding sponsors of publications; most productive authors; and highest-cited publications. Trends associated with this subset of publications were identified and presented. Bibliometric indicators of production were calculated, and bibliometric networks were constructed and visualized using the software tool VOSviewer.
    RESULTS: A total of 172,466 publications (42,331 open access), were published by 219,680 authors in 143 journals from 1938 to 2021. Since the 1940s, an upward trend with respect to the volume of publications can be observed, with a steep increase observed between the mid-2000s and mid-2010s. The journal that published the largest number of publications was the Journal of Natural Products (n = 15,144). The most productive countries included China (n = 45,860), the United States (n = 29,523), and Germany (n = 10,120); a number of the most common institutional affiliations and funding sponsors also originated from these three countries.
    CONCLUSIONS: The number of publications collectively published in TCAIM journals follows an upward trend. Given a high prevalence of TCAIM use among patients, increased acceptance of TCAIM among conventional healthcare providers, and growing interest in the research of TCAIM, future work should continue to investigate and track changes in the publication characteristics of the emerging research on this topic.

    Gender disparity in critical care publications: a novel Female First Author Index.
    Sowmya Chary, Karin Amrein, Djøra I Soeteman, Sangeeta Mehta, Kenneth B Christopher.
      BACKGROUND: Bibliometric analyses show gender bias against women in scientific publications and citations. We hypothesized that a metric of an individual senior author's inclusivity of women as first authors in critical care publications would predict gender inequality.METHODS: Using PubMed and Web of Science, we conducted a bibliometric analysis of original research publications in critical care from 2008 to 2018 in 11 specialty and general journals. Gender for first and senior authors was assigned by a gender determination application, and manually if needed. For all senior authors we defined the novel Female First Author Index (FFA-index) = #Female first authors in publications by an individual senior author/Total # publications by that senior author. We produced a novel interactive web-based application using the R package Shiny to increase potential utilization of the FFA-index.
    RESULTS: Of 7370 publications, 30.4% had female first authors and 15.5% had female senior authors. After adjustment for impact factor, journal, year of publication, number of authors, country, and gender determination accuracy, female senior authorship was associated with a 1.9-fold increase in female first authorship [OR = 1.85 (95% CI 1.62, 2.11); p < 0.001] compared with male senior authorship. The mean (SD) FFA-index for all individual senior authors was 30.5 (42.9); with a significant difference in FFA-index between male and female senior authors (27.6 versus 42.5, respectively; p < 0.001). The interactive web-based application (FFA-index App) produces the same FFA-index output as our study results.
    CONCLUSIONS: Female representation at prominent authorship positions in critical care publications is still far from achieving gender parity. By creating an authorship index score, we propose a frame of reference for the advancement of female first authorship.

    Gender Disparity in Citations in High-Impact Journal Articles.
    Paula Chatterjee, Rachel M Werner.
      Importance: Women are less likely to be promoted and hold leadership positions in academic medicine. How often academic articles are cited is a key measure of scholarly impact and frequently assessed for professional advancement; however, it is unknown whether peer-reviewed articles written by men and women are cited differently.Objective: To evaluate whether academic articles from high-impact medical journals written by men and women are cited differently.
    Design, Setting, and Participants: In this cross-sectional study of all original research and commentary articles from 5 high-impact medical journals (Annals of Internal Medicine, British Medical Journal, JAMA, JAMA Internal Medicine, and The New England Journal of Medicine) from 2015 to 2018, the gender of the primary and senior authors of each article were identified using an online database, and the number of times each article has been cited was identified using Web of Science. The number of citations by primary and senior author gender were then compared. Data were analyzed from July 2020 to April 2021.
    Exposures: Primary and senior authors' genders.
    Main Outcomes and Measures: Number of citations per article.
    Results: Among 5554 articles, women wrote 1975 (35.6%) as primary author and 1273 of 4940 (25.8%) as senior author. Original research articles written by women as primary authors had fewer median (interquartile range) citations than articles written by men as primary authors (36 [17-82] citations vs 54 [22-141] citations; P < .001) and senior authors (37 [17-93] citations vs 51 [20-128] citations; P < .001). Articles written by women as both primary and senior authors had approximately half as many median (interquartile range) citations as those authored by men as both primary and senior authors (33 [15-68] citations vs 59 [23-149] citations; P < .001). Differences in citations remained in each year of the study and were less pronounced among commentary articles.
    Conclusions and Relevance: In this study, articles written by women in high-impact medical journals had fewer citations than those written by men, particularly when women wrote together as primary and senior authors. These differences may have important consequences for the professional success of women and achieving gender equity in academic medicine.

    Altmetric Score Has a Stronger Relationship With Article Citations Than Journal Impact Factor and Open Access Status: A Cross-Sectional Analysis of 4,022 Sports Science Articles.
    Danilo de Oliveira Silva, Bianca Taborda, Marcella F Pazzinatto, Clare Ardern, Christian J Barton.
      OBJECTIVE: To assess the relationship of individual article citations in the Sport Sciences field to (i) journal impact factor; (ii) each article's open access status; and (iii) Altmetric score components.DESIGN: Cross-sectional.
    METHODS: We searched the ISI Web of Knowledge InCites Journal Citation Reports database "Sport Sciences" category for the 20 journals with the highest 2-year impact factor in 2018. We extracted the impact factor for each journal and each article's open access status (yes or no). Between September 2019 and February 2020, we obtained individual citations, Altmetric scores and details of Altmetric components (e.g. number of tweets, Facebook posts, etc.) for each article published in 2017. Linear and multiple regression models were used to assess the relationship between the dependent variable (citation number) and the independent variables article Altmetric score and open access status, and journal impact factor.
    RESULTS: 4,022 articles were included. Total Altmetric score, journal impact factor and open access status, respectively explained 32%, 14%, and 1% of the variance in article citations (when combined, the variables explained 40% of the variance in article citations). The number of tweets related to an article was the Altmetric component that explained the highest proportion of article citations (37%).
    CONCLUSION: Altmetric scores in Sports Sciences journals have a stronger relationship with number of citations than does journal impact factor or open access status. Twitter may be the best social media platform to promote a research article as it has a strong relationship with article citations.

      STATEMENT OF PROBLEM: A comprehensive bibliometric analysis to determine different aspects of the Journal of Prosthetic Dentistry is lacking.PURPOSE: The purpose of this bibliometric study was to analyze the characteristics of the Journal of Prosthetic Dentistry between 1970 and 2019.
    MATERIAL AND METHODS: The Web of Science Core Collection was used to retrieve 9 categories of the Journal of Prosthetic Dentistry, including keywords and terms used, cited documents published, the countries and organizations of the authors, references, and sources cited during this period. Data were exported to a software program and analyzed for each 10-year period and for the entire 50 years. The highest 10 in each category were reported. Co-occurrence, couthorships, and linkage were also reported.
    RESULTS: A total of 11 989 records were reached by the search on the Web of Science Core Collection database; of which, 10 638 (92.9%) were included in the analysis. Articles made up 91.1%, of all records, with 217 review documents (1.8%). The most productive decade was 1980 to 1989 with 2936 documents. The total number of citations of all documents (available period 1980 to 2019) including self-citations was 155 112. During the period 1970 to 2019, 14 837 terms were used. The total number of keywords was 4933 (available period 1990 to 2019). There were 15 382 authors, 82 countries, and 2113 organizations identified in articles published in the Journal of Prosthetic Dentistry during this period, with most from the United States. There were 43 027 authors, 95 324 references, and 14 594 sources cited in the Journal of Prosthetic Dentistry during the period surveyed.
    CONCLUSIONS: This bibliometric analysis provided a comprehensive overview of the impactful role of the Journal of Prosthetic Dentistry in contemporary dentistry, particularly in the field of prosthodontics.

    The h-index is no longer an effective correlate of scientific reputation.
    Vladlen Koltun, David Hafner.
      The impact of individual scientists is commonly quantified using citation-based measures. The most common such measure is the h-index. A scientist's h-index affects hiring, promotion, and funding decisions, and thus shapes the progress of science. Here we report a large-scale study of scientometric measures, analyzing millions of articles and hundreds of millions of citations across four scientific fields and two data platforms. We find that the correlation of the h-index with awards that indicate recognition by the scientific community has substantially declined. These trends are associated with changing authorship patterns. We show that these declines can be mitigated by fractional allocation of citations among authors, which has been discussed in the literature but not implemented at scale. We find that a fractional analogue of the h-index outperforms other measures as a correlate and predictor of scientific awards. Our results suggest that the use of the h-index in ranking scientists should be reconsidered, and that fractional allocation measures such as h-frac provide more robust alternatives.

    A Bibliometric Analysis of Overall and Top 100 Most-Cited Studies About Robotic Surgery Versus Open Surgery.
    Xiajing Chu, Peijing Yan, Na Zhang, Lufang Feng, Kangle Guo, Cuncun Lu, Tingting Lu, Chengbin Wang, Ke-Hu Yang.
      BACKGROUND: In the last 30 years, significant progress in the field of surgery has been achieved with the advent of robotic surgery. In this study, we aimed to conduct a bibliometric analysis to identify the distribution and characteristics overall and of the top 100 most-cited studies about robotic surgery versus open surgery.METHODS: A systematic search was conducted on March 26, 2021 using Web of Science Core Collection. Two reviewers independently screened documents, and the top 100 most-cited studies were identified. Excel 2019 and VOSviewer were used to collect the data, and visual information was obtained.
    RESULTS: A total of 2306 documents were searched from the Web of Science Core Collection, and 1065 journals and 2913 institutes were extracted. A significant growth was observed in the last 15 years. The number of citations from the United States accounted for 33.31% of the total number of citations. There were nine American institutes and one Swedish institute in the top 10 institutes. Four journals in the field of urology or gynecology were present in the top 10 published journals. Few global communications between authors, institutes, and countries authors were observed.
    CONCLUSION: The lack of close cooperation among scientific research institutions may have affected the industrialization process of surgical robots. Some developing countries, including South America and Africa, should seize the development opportunity of robotic surgery to improve the level of domestic research on robotic surgery.

    Kevin J Bondar, Dhanur Damodar, Nicholas C Schiller, Johnathon R McCormick, Nolan B Condron, Nikhil N Verma, Brian J Cole.
      Purpose: To analyze the 50 most-cited articles pertaining to "Bankart lesions," also known as anteroinferior labral tears, by means of citation analysis as well as to provide analysis and summary of the origins and trends of research on Bankart lesions.Methods: Scopus was used to query the literature on Bankart lesions. Included articles were related to Bankart lesions and the indications, risk factors, techniques, and outcomes of arthroscopic and open Bankart repair. The 50 most-cited articles were analyzed in the following areas: year of publication, citations in the most recent year, total citation count, contributing authors, institutions, countries, and journals, article classifications, and level of evidence.
    Results: Years of publication ranged from 1938 to 2013. There were 608 total citations in the most recent year. Total citation count was 12,441. Regarding country, journal, and authorship, United States, R. A. Arciero, and Arthroscopy were the highest respective contributors. Rush University had the greatest number of publications. The most common article classification was clinical outcomes. Of 49 clinical articles, the most frequent Level of Evidence was IV. The majority of the top 50 Bankart literature consisted of case series and retrospective studies performed in the United States.
    Conclusions: Our findings are consistent with the hypothesis that the 50 most-cited articles about Bankart lesions are predominantly U.S.-based, produced by academic orthopaedic groups, clinical outcomes articles, and of Level IV and V evidence. This list of articles should serve as a reference tool for any orthopaedist looking to review Bankart literature.

    Evaluating obesity publications: from bibliometrics to altmetrics.
    Azadeh Aletaha, Akbar Soltani, Firoozeh Dokhani.
      Purpose: study the bibliometrics indicators of Iranian authors in the field of obesity and Correlation Comparison between conventional citation counts and altmetrics scores from 2005 to 2019.Methods: The study uses bibliometric characteristics and altmetric analysis. Population consists of 5359 articles out of 8220 in the field of obesity which have specified Iran as the affiliated country and indexed by Scopus between 2005 to 2019. Citations was extracted from Scopus database and visualized bibliographic data by VOS viewer software version 17, as well as Altmetric Explorer was applied for altmetrics data. The spearman correlation was used to analyze distributions of altmetrics and citation. Statistical analysis was utilized using SPSS software version 17.
    Results: According to altmetrics finding among 2221 articles, 90% of articles had focused on different social media. The major interaction of researches has taken place in Twitter respectively News and Facebook. a positive correlation (r = 0.31) has been found between citation and altmetrics. As a result, Institutes with the highest degree of co-authorship had the top 10 articles with the highest altmetrics score.
    Conclusion: Depending on the degree of correlation suggest that altmetrics should be seen as complements to, rather than alternatives to citations. Altmetrics indicators will be very useful for health policymaking and aid them with identifying important factors driving altmetric events. Also it could help to reveal the hidden value of some medical papers. Our findings can help international communications for scientific collaboration at the level of business and health care industry, and emergency managers gain a comprehensive understanding of the research area.

    Muhammad Irfan Sheeraz, Ungku Norulkamar Ungku Ahmad, Muhammad Ishtiaq Ishaq, Muhammad Sarfraz, Khalil Md Nor.
      The organizational justice terminology has had a long journey to become one of the significant contributors to organizational success. Recently, an intense global upsurge in the use of organizational justice terms in publications has forced us for this bibliometric analysis in order to look at the overall publications on organizational justice. The objective of the current research is to advance knowledge about organizational justice research trends using Scopus database and bibliometric analysis research. The analysis was performed to see the publication trends between the years 1941 and 2018; it used authors, journals, countries, academic discipline, research institutes/universities, and various keywords related to organizational justice as search words. After careful consideration and using multiple checkpoints for eliminating irrelevant studies, 5,650 research articles were analyzed. In the realm of organizational justice, procedural justice was the most frequently occurred among other dimensions. Moreover, variables such as organizational trust, job satisfaction, organizational commitment, citizenship behavior, ethics, and turnover are major concepts that occurred within organizational justice research. Some variables with infrequent occurrences, along with future recommendations and study limitations, are also discussed.

    Publication Trends in Physical Medicine and Rehabilitation in Japan from 2001 to 2019.
    Yoshitaka Wada, Nobuyuki Kawate.
      Objectives: The aim of this study was to examine, using PubMed, the number of articles in the field of physical medicine and rehabilitation medicine originating in Japan, especially those containing high-quality scientific evidence (randomized controlled trials [RCTs], systematic reviews, meta-analyses) and those published in high impact factor journals.Methods: We searched the PubMed database to identify articles, RCTs, systematic reviews, and meta-analyses from Japan covering physical medicine and rehabilitation published between 2001 and 2019; we then calculated the proportion of articles from Japan. Additionally, using Journal Citation Reports, we selected the top ten highest impact factor journals on "Rehabilitation" each year between 2001 and 2019. For each year, we searched PubMed for the total number of articles in these top ten journals and for articles originating in Japan. The Cochran-Armitage test was used to evaluate the change in the proportion of publications from Japan over time.
    Results: The proportion of articles on physical medicine and rehabilitation originating in Japan increased from 2001 to 2019 (P<0.0001). An increase in the percentages of systematic reviews (P=0.046) and meta-analyses (P=0.0013) originating in Japan and a decrease in the percentage of original articles published in the top ten highest impact factor journals were demonstrated (P=0.002). However, there was no change in the percentage of RCTs from Japan over time (P=0.055).
    Conclusions: Our findings suggest that the proportion of articles from Japan containing high-quality scientific evidence is increasing. However, there is a need to expand the support system for research while considering the quality of research.

    Contribution of Arab world in transplant research: A PubMed-based bibliometric analysis.
    LemirMajed E L Ayoubi, Jad E L Masri, Marc Machaalani, Said E L Hage, Pascale Salameh.
      BACKGROUND: The Arab world consists of 22 countries situated in the Middle East and North Africa, tied together by linguistic and cultural bonds. Over numerous past decades, this region tended to fall behind regarding biomedical research. Organ, tissue, and cell transplantation are life-saving and life-improving treatments for various diseases. Given the positive correlation between research activity and the improvement of the clinical frame of transplantation, this article intended to examine the regional activity of transplantation research between 2005 and 2019.METHODS: Using the PubMed database, the number of transplantation-related articles published by each country, and regarding 26 different procedures, was assessed. The results were normalized with respect to each country's average population & average Gross Domestic Product (GDP). In addition, the co-occurrence of keywords and the co-authorships were analyzed by VOS Viewer.
    RESULTS: Arab countries contributed to 1.25% of total transplantation publications. The number of transplantation publications had an inflection in 2013, with the last six years alone contributing to 65.27% of the overall regional transplantation-related publications. Kuwait and Lebanon ranked first in terms of publications per million persons, while Egypt ranked first in terms of publications per national GDP. Stem cell, bone & kidney transplantations had the highest number of Arab transplantation-related publications. Low levels of collaboration between authors and organizations were observed, besides a modest but increasing trend towards experimental work on animals and newer therapies.
    CONCLUSION: Despite the increase in transplant-related research activity in recent years, the Arab world still lags behind in this field compared to the worldwide contribution.

    Female Participation in Academic European Neurosurgery-A Cross-Sectional Analysis.
    Catharina Conzen, Karlijn Hakvoort, Hans Clusmann, Anke Höllig.
      The study aims to provide data on authors' gender distribution with special attention on publications from Europe. Articles (October 2019-March 2020) published in three representative neurosurgical journals (Acta Neurochirurgica, Journal of Neurosurgery, Neurosurgery) were analyzed with regard to female participation. Out of 648 publications, 503 original articles were analyzed: 17.5% (n = 670) of the 3.821 authors were female, with 15.7% (n = 79) females as first and 9.5% (n = 48) as last authors. The lowest ratio of female first and last authors was seen in original articles published in the JNS (12.3%/7.7% vs. Neurosurgery 14.9%/10.6% and Acta 23.0/11.5%). Articles originated in Europe made up 29.8% (female author ratio 21.1% (n = 226)). Female first authorship was seen in 20.7% and last authorship in 10.7% (15.3% and 7.3% were affiliated to a neurosurgical department). The percentages of female authorship were lower if non-original articles (n = 145) were analyzed (11.7% first/4.8% last authorships). Female participation in editorial boards was 8.0%. Considering the percentages of European female neurosurgeons, the current data are proportional. However, the lack of female last authors, the discrepancy regarding non-original articles and the composition of the editorial boards indicate that there still is a structural underrepresentation and that females are limited in achieving powerful positions.

    Research Trends in Octopus Biological Studies.
    Anna Di Cosmo, Claudia Pinelli, Anna Scandurra, Massimo Aria, Biagio D'Aniello.
      Octopuses represent interesting model studies for different fields of scientific inquiry. The present study provides a bibliometric analysis on research trends in octopuses biological studies. The analysis was executed from January 1985 to December 2020 including scientific products reported in the Web of Science database. The period of study was split into two blocks ("earlier period" (EP): 1985-2010; "recent period" (RP): 2011-2020) to analyze the evolution of the research topics over time. All publications of interest were identified by using the following query: ((AK = octopus) OR (AB = octopus) OR (TI = octopus)). Data information was converted into an R-data frame using bibliometrix. Octopuses studies appeared in 360 different sources in EP, while they increased to 408 in RP. Sixty countries contributed to the octopuses studies in the EP, while they were 78 in the RP. The number of affiliations also increased between EP and RP, with 835 research centers involved in the EP and 1399 in the RP. In the EP 5 clusters (i.e., "growth and nutrition", "pollution impact", "morphology", "neurobiology", "biochemistry") were represented in a thematic map, according to their centrality and density ranking. In the RP the analysis identified 4 clusters (i.e., "growth and nutrition", "ecology", "pollution impact", "genes, behavior, and brain evolution"). The UK with Ireland, and the USA with Canada shared the highest number of publications in the EP, while in the RP, Spain and Portugal were the leading countries. The current data provide significant insight into the evolving trends in octopuses studies.

    STEAM in education: a bibliometric analysis of performance and co-words in Web of Science.
    José-Antonio Marín-Marín, Antonio-José Moreno-Guerrero, Pablo Dúo-Terrón, Jesús López-Belmonte.
      Background: Emerging methodologies that apply and integrate science, technology, engineering, art, and math (STEAM) in education have appeared in recent years as a pedagogical alternative providing more holistic and attractive education.Method: The research methodology used in this work is of a bibliometric nature. Specifically, an academic performance analysis and a co-word analysis has been carried out. The term STEAM was analyzed in the Web of Science (WoS) database. The WoS programs Analyze Results, Creation Citation Report, and SciMAT were used. A total of 1116 manuscripts were analyzed.
    Results: The results show that studies in the field education of STEAM began in 2006 and have continued uninterruptedly up to the present day, although interest generated in the scientific community has been irregular.
    Conclusions: It can be concluded that STEAM studies have not had an established and robust line of research over time, although it can be observed that the trends in this aspect are focused on the scientific branch of education. In addition, the topics of study on STEAM include points related to gender differences, the influence of STEAM on people of different races, the skills developed by students, and training teachers to implement teaching and learning processes with STEAM.

    Visual abstracts do not increase some impact scores more than conventional abstracts of clinical research: A retrospective cohort study.
    Vaibhav Aggarwal.
      BACKGROUND AND OBJECTIVE: We examined whether the use of visual abstracts on social media platforms can improve comprehensive social media and conventional metrics such as total altmetric attention score, full text page views and citation counts (study outcomes) through retrospective cohort study.METHODS: We included all original research articles (Total 307 articles: N = 69 in visual abstract group and N = 238 in control group) published between July 2018 and January 2019 in the JAMA, BMJ and the NEJM and used negative binomial regression to adjust for article characteristics.
    RESULTS: Adjusted analysis showed no significant differences between articles with and without visual abstracts in the altmetric attention score (p = 0.37) and in number of page views (p = 0.44). Citations in the Web of Science core collection were found to be statistically significant favouring control group (p = 0.028). We also found no significant differences in altmetric attention score and page views after stratification for article type [randomised controlled trial (RCT) vs. non-RCT]. Citations counts were found to be borderline significant for RCT (p = 0.04) and non-significant for non-RCT.
    CONCLUSION: Visual abstracts might not be effective in disseminating scientific research. We should look at other innovative ways to improve the visibility of the research.

    A Bibliometric Meta-Analysis of Colistin Resistance in Klebsiella pneumoniae.
    Ozioma Forstinus Nwabor, Pawarisa Terbtothakun, Supayang P Voravuthikunchai, Sarunyou Chusri.
      Colistin is a last resort antibiotic medication for the treatment of infections caused by carbapenem-resistant Klebsiella pneumoniae. In recent years, various mechanisms have been reported to mediate colistin resistance in K. pneumoniae. This study reports a bibliometric analysis of published articles retrieved from the Scopus database relating to colistin resistance in K. pneumoniae. The research trends in colistin resistance and mechanisms of resistance were considered. A total of 1819 research articles published between 1995 and 2019 were retrieved, and the results indicated that 50.19% of the documents were published within 2017-2019. The USA had the highest participation with 340 (14.31%) articles and 14087 (17.61%) citations. Classification based on the WHO global epidemiological regions showed that the European Region contributed 42% of the articles while the American Region contributed 21%. The result further indicated that 45 countries had published at least 10 documents with strong international collaborations amounting to 272 links and a total linkage strength of 735. A total of 2282 keywords were retrieved; however, 57 keywords had ≥15 occurrences with 764 links and a total linkage strength of 2388. Furthermore, mcr-1, colistin resistance, NDM, mgrB, ceftazidime-avibactam, MDR, combination therapy, and carbapenem-resistant Enterobacteriaceae were the trending keywords. Concerning funders, the USA National Institute of Health funded 9.1% of the total research articles, topping the list. The analysis indicated poor research output, collaboration, and funding from Africa and South-East Asia and demands for improvement in international research collaboration.

    A Survey of Iranian Retracted Publications Indexed in PubMed.
    Mohammad Javad Mansourzadeh, Javad Ghazimirsaeid, Nadia Motamedi, Ali Najafi, Auwal Abdullahi Abubakar, Hossein Dehdarirad.
      Background: Retraction is a mechanism for correcting the literature and a warning for readers in relation to publications that contain serious flaws or erroneous data. As a result of growth and development of Iranian publications in the last two decades, that brings unethical behavior of researchers led to retraction of their publications. We aimed to investigate Iranian retracted publications indexed in PubMed database.Methods: All Iranian retracted publications published in PubMed up to Dec 2017 have been retrieved. Bibliographic information of retracted publications, retraction notice, time lag between article publication date and the date of retraction notice, reasons of retraction, Issuer of retraction and acknowledge information of retracted publication were recorded. Additionally, citation data of retracted publications before 2013 were analyzed.
    Results: Overall, 164 Iranian retracted publications were identified. Meantime lag was 20.8 months. "Islamic Azad University" and "Tehran University of Medical Sciences (TUMS)" were two affiliations that have received highest number of retracted publications. The most issuer of retraction publications was editor-in-chief and the most mentioned reasons for retractions were authorship issues, plagiarism, and redundant publication. Thirty-three (20.12%) publications have received funds from various agencies. Citation study of retracted publications indicates that these publications have received 789 citations (Citation per publication=11.6).
    Conclusion: Although Iranian retracted publications represent small portion of all Iranian publications, but the number of retracted publications has increased. More than half of retracted publications have had authorship issues and plagiarism that requires more attention to research ethics authorities.

    Growth of science in activated sludge modelling - a critical bibliometric review.
    Markus Ahnert, Peter Krebs.
      In this paper, the tool of bibliometric analysis is applied to the field of activated sludge modelling and its suitability as a first step of a literature analysis is assessed. The analysis is applied to the total dataset considered as well as a time-based classification. It can be shown that this tool is very well suited to filtering the relevant authors and publications, thus enabling a subsequent visual review. The methodology presented can also be applied to sub-disciplines or other subject areas. However, the sole use of the multiple statistical and visual tools is critically questioned. Thus, misinterpretations and apparent findings can result from structural problems in the data or parameters used. Not all of the metrics used are suitable for finding relevant publications, but rather for ranking the criteria studied. However, the latter represents the most widespread application of bibliometrics. From the analysis of the keywords, it could be deduced that there has been a temporal shift from fundamental model aspects to detailed questions such as the integration of sorption and adsorption processes or anaerobic digestion. The modelling of biological phosphorus removal has also surprisingly lost a great amount of importance in the scientific literature.

    Praveen Koovalamkadu Velayudhan, Alka Singh, Aditya Korekallu Srinivasa.
      This research article attempts a bibliometric analysis of global research on biofertilizers carried out from 2000 to 2019. The main purpose of this analysis is in technology foresight; to understand where the research interest lies within the domain of biofertilizer and also to identify the major research networks. The analysis is based on 344 research articles identified using the ISI Web of Science tool, which is processed further using VOSviewer. The results demonstrated that there is an increase in the number of articles, particularly from countries like Brazil, India China, the USA, and Iran. The research focus has been on the assessment of nitrogen fixation capacity of biofertilizers, and the yield improvement due to biofertilizers, and the economics of biofertilizer application. Our findings can act as a useful reference for the researchers, and provide insights for directing future research on biofertilizers.

    Savannah C Roy, David W Wassef, Wissam A Nasser, Nicole I Farber, Christina H Fang, Soly Baredes, Stacey T Gray, Jean Anderson Eloy.
      OBJECTIVE: To investigate the demographics of CORE grant recipients (Centralized Otolaryngology Research Efforts) over the last decade and evaluate disparity among recipients as compared with otolaryngology overall. To assess whether procurement of a grant predicts pursuit of an academic career.STUDY DESIGN: Analysis of grant recipients' bibliometrics.
    SETTING: Academic medical center.
    METHODS: The list of recipients of grants from 2010 to 2019 was obtained from the website of the American Academy of Otolaryngology-Head and Neck Surgery. Demographics of recipients were collected through an internet search, including gender, race, residency program, and h-index. Recipients from 2010 were searched to determine current academic faculty rank. Univariate and multivariate analyses were used to compare these factors with otolaryngology overall.
    RESULTS: The distribution of gender among recipients over the last decade remained nearly constant, with no significant difference versus residents in otolaryngology (P > .05). However, there were significantly more female recipients when adjusted for gender differences in the field overall (P < .01). Asians were relatively overrepresented, while Black and Hispanic residents were underrepresented (P < .01). Many recipients (52.6%) trained at institutions recognized as the best training programs with reputations for quality research output. The h-index of recipients decreased over the last decade (P < .01). The h-index of duplicate winners was significantly higher than those of nonduplicate winners (P < .01). After adjusting for gender and rank, recipients were significantly more likely to hold academic positions (P < .01).
    CONCLUSION: CORE grants are favorably distributed as related to gender and racial disparities, and recipients frequently go on to achieve high levels of academic success.

    A further increase in Acta Physiologica's impact factor.
    P B Persson.
      Another good year for Acta Physiologica. Our current impact factor increased to 6.3. Of course, the impact factor is not very useful to measure science performance and flawed in many ways.1, 2 Keeping this in mind, we are proud that, as for the past recent years,3, 4 Acta Physiologica is in the top 10% of the physiology journals. Acta Physiologica is the leading physiology journal to publish original articles covering all physiology disciplines and funding agencies recognize this.5.

    What are the variables associated with Altmetric scores?
    Amanda Costa Araujo, Adriane Aver Vanin, Dafne Port Nascimento, Gabrielle Zoldan Gonzalez, Leonardo Oliveira Pena Costa.
      BACKGROUND: Social media has been used to disseminate the contents of scientific articles. To measure the impact of this, a new tool called Altmetric was created. Altmetric aims to quantify the impact of each article through online media. This systematic review aims to describe the associations between the publishing journal and published article variables and Altmetric scores.METHODS: Searches on MEDLINE, EMBASE, CINAHL, CENTRAL, and Cochrane Library were conducted. We extracted data related to both the publishing article and the publishing journal associated with Altmetric scores. The methodological quality of included articles was analyzed by the Appraisal Tool for Cross-sectional Studies.
    RESULTS: A total of 19 articles were considered eligible. These articles summarized a total of 573,842 studies. Citation counts, journal impact factor, access counts, papers published as open access, and press releases generated by the publishing journal were associated with Altmetric scores. The magnitude of these associations ranged from weak to strong.
    CONCLUSION: Citation counts and journal impact factor are the most common variables associated with Altmetric scores. Other variables such as access counts, papers published in open access journals, and the use of press releases are also likely to be associated with online media attention.
    SYSTEMATIC REVIEW REGISTRATION: This review does not contain health-related outcomes. Therefore, it is not eligible for registration.

    Mapping themes trends and knowledge structure of trophoblastic invasion, a bibliometric analysis from 2012-2021.
    Wenyan Gao, Liyuan Yang, Bei Shi.
      OBJECTIVES: Trophoblastic invasion at the maternal-fetal interface can affect pregnancy outcomes. To describe an intuitive theme trends and knowledge structure of trophoblastic invasion-related literature from a bibliometric perspective, and provide researchers with new research hotspots.STUDY DESIGN: The literature form PubMed database related to trophoblastic invasion from January 1, 2012 to April 30, 2021 were extracted, and then biclustering analysis, co-word analysis, strategy diagram and social network analysis were performed to provide immature, or newly emerging research hotspots for researchers.
    RESULTS: A total of 96 high-frequency medical subjects heading terms were extracted and classified into 6 clusters. Themes in the first and second quadrant of strategy diagram, including trophoblasts metabolism, placenta metabolism, pre-eclampsia, etc., as the mature parts of the research on trophoblastic invasion have been well developed. On the other hand, themes in the third and fourth quadrants of strategy diagram, such as embryo implantation and trophoblasts immunology, pregnancy complication, matrix metalloproteinase and trophoblasts metabolism, habitual abortion and trophoblasts metabolism, etc., are immature themes. Social network analysis suggests that themes at the edge, such as habitual abortion / metabolism, placenta / immunology, natural killer cells / physiology, natural killer cells / immunology, embryo implantation / immunology, are considered new research hotspots and have considerable research space.
    CONCLUSION: By analyzing the research hotspots related to trophoblastic invasion, immature themes and emerging hotspots deserve more attention and can be considered as hints when launching new research projects.

    Theresa W Gyorkos, Hélène Carabin, Maneesh Phillip, Leshawn Benedict, Amy Davis, Janet Hatcher Roberts, Kishor M Wasan, Momar Ndao, Alison Krentel.
      BACKGROUND: The World Health Organization's (WHO) Neglected Tropical Disease (NTD) Road Map for 2021-2030 was recently endorsed by all member states at the World Health Assembly in November 2020. Although only 3 of the 20 NTDs are endemic in Canada (i.e., echinococcosis, rabies, and scabies), the Canadian research community has contributed to advancing the knowledge base of all 20 NTDs. Previous research comprehensively detailed Canadian research on 11 NTDs between 1950 and 2010 using a network analysis approach. The specific objective of the present analysis was to update the publication record over the last decade (2010-2019) to include all 20 NTDs.MATERIALS AND METHODS: A bibliometric analysis was conducted in Scopus and Web of Science databases (for English or French articles published between January 1, 2010 and December 31, 2019) using appropriate search terms for each of the 20 NTDs and where at least 1 of the authors had a Canadian institution address. A 21st search was added to include publications including multiple NTDs or a discussion of NTDs in general. Following assessment of inclusion and exclusion criteria, 2 reviewers independently screened all abstracts, with discordant observations rereviewed to arrive at an agreement. Duplicates were removed.
    RESULTS: A total of 1,790 publications were retrieved (1,738 with a disease-specific NTD focus and 52 with a general NTD focus, resulting in 1,659 unique publications), giving an average of over 160 articles per year. Over 80% were classified as full-length research articles. The top 3 journals in terms of frequency were PLOS Neglected Tropical Diseases, PLOS ONE, and the American Journal of Tropical Medicine and Hygiene. Authors' institutions were from all Canadian provinces. While all 20 NTDs were addressed in these publications, the 5 most commonly studied were leishmaniasis, dengue fever and chikungunya, Chagas disease, soil-transmitted helminthiases, and rabies.
    CONCLUSIONS: Canadian researchers across the country have contributed to the evidence base of all 20 NTDs, publishing an average of over 160 publications per year between 2010 and 2019. As WHO NTD Road Map 2021-2030 rolls out globally, the Canadian research community, in collaboration with its partners and in solidarity with people living in vulnerable circumstances in endemic regions worldwide, is well positioned to meet future research challenges so that the goal of eliminating the disease burden attributable to NTDs can be achieved.

    Does Publication History Predict Future Publication Output in Orthopaedics?
    Madison L Goss, Sarah McNutt, Jesse E Bible.
      Background The number of publications is widely used as a measure of academic productivity in the field of orthopaedics. How "productive" a physician is has a great influence on consideration for employment, compensation, and promotions. Predictors of potential high-output researchers would be of value to the orthopaedic department and university leadership for new faculty evaluation. Methods The study population included orthopaedic faculty from the top 10 orthopaedic institutions in the United States. Their names and the number of publications at each point in their training (medical school, residency, and fellowship) and early career (first five and 10 years following fellowship) along with a total number of publications to date were collected by using PubMed. Results Strong correlations were seen between publications during total training and publications output in the first five years following fellowship (rs =0.717, P<0.0001). However, no significant correlations were found comparing publications during each stage of training and the first 10 years following fellowship. A moderate positive correlation was found when comparing publications during medical school and residency output (rs =0.401, P<0.0001). Conclusions The data presented here may be utilized by department chairs during the evaluation of faculty and candidates to not interpret the number of publications during training and early career as a gauge of research interest and potential for future publications. Program directors may also use the only moderate correlation between publications in medical school and residency when evaluating applications as support of a more holistic review of applicants to determine research interest.

    Abstract-To-Publication Rates From Australian Society of Medical Imaging and Radiation Therapy Conferences.
    Jo-Anne Pinson.
      PURPOSE: To review authorship details of Australian Society of Medical Imaging and Radiation Therapy (ASMIRT) conference accepted abstracts for medical imaging and radiation therapy disciplines; identify the Australian or international institutions that submitted abstracts; and to determine the rates of ASMIRT conference abstracts to papers and their citation number.METHODS: Retrospective analysis of oral and poster conference abstracts published in the Journal of Medical Radiation Sciences (JMRS) from 2015 through 2017 identified 581 Australian and international abstracts. Of these, 513 Australian abstracts were analyzed using Google Scholar, PubMed, and Google databases. Abstracts were allocated to medical imaging or radiation therapy disciplines. Abstract titles, key words, institutions, and author names were used to search for peer-reviewed papers. Papers were authenticated through open access, publicly available author information, or library access.
    RESULTS: During a 3-year period, medical imaging and radiation therapy averaged 12.7 ± 7.8 and 12.7 ± 2.8 abstracts and posters, respectively. Oral abstracts averaged 70.0 ± 26.9 (medical imaging) and 76.3 ± 24.0 (radiation therapy). A total of 111 publications from 117 Australian conference presentations were distributed across 53 journals or books between the 2 disciplines. ASMIRT conference presentation to full publication rate was 18.3% (medical imaging) and 24.7% (radiation therapy). The citation number exceeded 270 for medical imaging publications and 540 for radiation therapy publications at the time of writing.
    DISCUSSION: Many factors affect whether medical radiation practitioners present their research at conferences. Conferences in Australia have smaller audiences compared with well-known journals such as JMRS, which limits the dissemination of data and the research impact. Research collaborations can improve publication opportunity and build research capacity, while the publication citation number can reflect the impact of the published research. The publication of research findings is a challenging process but essential to sharing medical knowledge and improving clinical practice.
    CONCLUSION: The rate of ASMIRT conference abstract to full publication was at the lower end of reported literature. This finding provides a benchmark for future studies on abstract-to-publication rates in Australia and globally.

    Publication misrepresentation amongst pediatric anesthesiology fellowship applicants: A retrospective single center cohort study.
    Ashin Mehta, Palak Patel, Thomas J Caruso, Thomas Anthony Anderson.
      BACKGROUND: Many medical specialties have found publication misrepresentation in residency and fellowship applications, but pediatric anesthesia fellowship application data is lacking.AIMS: We sought to determine the prevalence of publication misrepresentation among pediatric anesthesia fellowship applications.
    METHODS: In this retrospective cohort study, fellowship applications to Stanford University's pediatric anesthesiology fellowship program from 2009 to 2019 were reviewed. Only peer-reviewed journal articles listed as accepted or published were included. Nine additional variables were collected: applicant age, gender, citizenship status, American vs. international medical school, public vs. private medical school, allopathic doctor versus osteopathic doctor, number of years between college and medical school, additional degrees, and application year. The primary outcome was the rate of publication misrepresentation, defined as peer-reviewed journal citations listed on the application that could not be verified or on which the applicant was not listed as an author. Secondary outcomes were the associations between publication misrepresentation and the additional collected variables.
    RESULTS: 1280 peer-reviewed journal publications from 877 applicants were reviewed. 3.4% of all citations listed as peer-reviewed journal articles were misrepresented and 9.0% of all applicants with at least 1 publication had ≥ 1 misrepresented publications. 30.2% of publications labelled "misrepresented" were located in our search of databases but did not have the applicant as an author, and 69.8% could not be located using the search databases. Only one of the 9 collected variables (public vs private medical school) was significantly associated with publication misrepresentation.
    CONCLUSIONS: In this single center retrospective study, publication misrepresentation was found to occur in one out of 11 pediatric anesthesia fellowship applications with at least one publication. Since residency and fellowship applicant publications may be heavily weighted during the application process, programs may want to include additional inquiries into the accuracy of applicant publications.

    A critical review on altmetrics: can we measure the social impact factor?
    Cristina García-Villar.
      Altmetrics measure the digital attention received by a research output. They allow us to gauge the immediate social impact of an article by taking real-time measurements of how it circulates in the Internet. While there are several companies offering attention scores, the most extensive are Altmetric.com (Altmetric Attention Score-AAS) and Plum X (Plum Print). As this is an emerging topic, many medical specialities have tried to establish if there is a relationship between an article's altmetric data and the citations it subsequently receives. The results have varied depending on the research field. In radiology, the social network most used is Twitter and the subspeciality with the highest AAS is neuroimaging. This article will review the process involved from the start when an article is published through to finally obtaining its altmetric score. It will also address the relationship between altmetrics and more traditional approaches focusing on citations in radiology and will discuss the advantages and limitations of these new impact indicators.

    Occupational risk factors of contracting COVID-19 among health workers: A systematic review.
    Haizhe Jin, Yuxiao Chen, Quanwei Fu, Qingxing Qu.
      BACKGROUND: With the spread of COVID-19 and the worsening global prevention and control situation, the risk of infection faced by health workers has been unprecedented. It is necessary to fully understand the occupational risks of health workers to protect them and reduce their risk of infection.OBJECTIVE: This study aimed to obtain comprehensive and detailed information on occupational risk factors of infectious diseases for HWs in different dimensions and to propose control strategies for three risk dimensions to protect HWs who are at high risk of infection during the pandemic.
    METHODS: A total number of 619 articles published from 2010 to 2021 were searched to conduct bibliometric analysis, which were retrieved in the Web of Science database with defined search terms. There were 26 articles met the criteria, and they were screened to identify occupational risk factors.
    RESULTS: We conducted an analysis of cited institutions, co-citation network analysis of journals, and references from bibliometric analysis. Nine risk factors were extracted, and they were classified and sorted into three dimensions. Infection control strategies for each dimension were proposed.
    CONCLUSIONS: The risk of infection faced by HWs is unprecedented. Medical institutions should pay more attention to the nine risk factors that we identified and use the three risk dimensions to carry out risk identification and infection control to reduce the infection risk of HWs and protect them better.

    A 50-Year Overview of the Coronavirus Family with Science Mapping Techniques: A Review.
    Ayhan Tabur, Ali Arslanoğlu.
      Background: The COVID-19 pandemic from the coronavirus family is the most important agenda of today's world, also called the "New World". In this outbreak period, declared a pandemic by WHO and affected the whole world and humanity on a global scale, all kinds of scientific information and evidence-based sharing on the subject gained great importance.Methods: Overall, 12,301 articles from the web of Science (WOS) Core Collection database were analyzed using SciMAT software, conducted to examine the development of coronavirus publications in the process and to reveal the scientific mapping related to the subject. To analyze the development in the process based on periods, the articles covering the 50 years were compared as five periods of 10 years.
    Results: The most publications with the Coronavirus theme were made between 2010 and 2020 (n=1020), the total number of citations of these articles was 15,966 and the h-index value was 54. The theme "Coronavirus" was associated with the themes "infection" (w=0.04), "SARS" (w=0.03), "virus" (w=0.04), "identification" (w=0.05) and "swine" (w=0.03). Due to the recent emergence of the COVID-19 theme, it was found to be directly related to the "outbreak" theme (w=0.01). In terms of the distribution of the articles on coronavirus by country, most articles were published by the USA. This country is followed by China, Germany, England and the Netherlands.
    Conclusion: This research on the coronavirus family can offer a holistic view of the virus family in the scientific world and can make a scientific contribution to the fight against the virus by creating awareness on this issue.

    CAR-based cell therapy: evaluation with bibliometrics and patent analysis.
    Yajun Yuan, Qihan Fu, Yaqun Zhang, Danhai Xu, Yeqing Wu, Qiufei Qiu, Wuyuan Zhou.
      Chimeric antigen receptors-based cell therapies have shown impressive preclinical and clinical success and revolutionized biomedicine. However, the link between science and invention, the impact of international cooperation, and the influence and prestige of CARs research have not been explored. This study analyzed the landscape of peer-reviewed articles and patents related to CARs. A total of 5,681 publications were analyzed using bibliometrics and machine learning-based text mining to assess publication metrics, subject areas, and research hotspots. 5,010 Inpadoc families were also analyzed for patent filing trends, priority countries, and applicant and inventor rankings. The results show that CARs research has the following distinctive features: high research prestige among research community; strong global geographical bias in both academic output and patenting patterns; strong links between science and invention, but significant differences among countries; and an inverse relationship between country size and international collaboration rates.

    Academic Radiology in the United States: Defining Gender Disparities in Faculty Leadership and Academic Rank.
    Abhishek K Goswami, Nima Kokabi, Minhaj S Khaja, Wael E Saad, Akram Khaja, Aksal P Vashi, Amrit Bhatia, Lingyi Peng, Suma Yellamraju, Rithvik Sarasani, Harsha Sripadrao, Laura K Findeiss, Janice M Newsome, Carolyn C Meltzer, Bill S Majdalany.
      RATIONALE AND OBJECTIVES: Female physicians in academic medicine have faced barriers that potentially affect representation in different fields and delay promotion. Little is known about gender representation differences in United States academic radiology departments, particularly within the most pursued subspecialties.PURPOSE: To determine whether gender differences exist in United States academic radiology departments across seven subspecialties with respect to academic ranks, departmental leadership positions, experience, and scholarly metrics.
    MATERIALS AND METHODS: In this cross-sectional study from November 2018 to June 2020, a database of United States academic radiologists at 129 academic departments in seven subspecialties was created. Each radiologist's academic rank, departmental leadership position (executive-level - Chair, Director, Chief, and Department or Division Head vs vice-level - vice, assistant, or associate positions of executive level), self-identified gender, years in practice, and measures of scholarly productivity (number of publications, citations, and h-index) were compiled from institutional websites, Doximity, LinkedIn, Scopus, and official NPI profiles. The primary outcome, gender composition differences in these cohorts, was analyzed using Chi2 while continuous data were analyzed using Kruskal-Wallis rank sum test. The adjusted gender difference for all factors was determined using a multivariate logistic regression model.
    RESULTS: Overall, 5086 academic radiologists (34.7% women) with a median 14 years of practice (YOP) were identified and indexed. There were 919 full professors (26.1% women, p < 0.01) and 1055 executive-level leadership faculty (30.6% women, p < 0.01). Within all subspecialties except breast imaging, women were in the minority (35.4% abdominal, 79.1% breast, 12.1% interventional, 27.5% musculoskeletal, 22.8% neuroradiology, 45.1% pediatric, and 19.5% nuclear; p < 0.01). Relative to subspecialty gender composition, women full professors were underrepresented in abdominal, pediatric, and nuclear radiology (p < 0.05) and women in any executive-level leadership were underrepresented in abdominal and nuclear radiology (p < 0.05). However, after adjusting for h-index and YOP, gender did not influence rates of professorship or executive leadership. The strongest single predictors for professorship or executive leadership were h-index and YOP.
    CONCLUSION: Women academic radiologists in the United States are underrepresented among senior faculty members despite having similar levels of experience as men. Gender disparities regarding the expected number of women senior faculty members relative to individual subspecialty gender composition were more pronounced in abdominal and nuclear radiology, and less pronounced in breast and neuroradiology. Overall, h-index and YOP were the strongest predictors for full-professorship and executive leadership among faculty.
    KEY RESULTS: ● Though women comprise 34.7% of all academic radiologists, women are underrepresented among senior faculty members (26.1% of full professors and 30.6% of executive leadership) ● Women in junior faculty positions had higher median years of practice than their male counterparts (10 vs 8 for assistant professors, 21 vs 13 for vice leadership) ● Years of practice and h-index were the strongest predictors for full professorship and executive leadership.

    Geographical distribution and international collaboration of Latin American and Caribbean scientific publications on tuberculosis in Pubmed.
    Cristina Torres-Pascual, Héctor Javier Sánchez-Pérez, Pilar Ávila-Castells.
      OBJECTIVE: The objective of the study was to describe the geographical coverage of Latin American and Caribbean scientific publications on tuberculosis and its international collaboration.MATERIALS AND METHODS: The records were retrieved from the PubMed database (2009-2018), limiting the search to Latin American and Caribbean countries. Articles were analyzed in several categories, such as the total number, countries, institutions, authors, collaborations, and citations. The software UCINET and VOSviewer were used.
    RESULTS: 2,495 items were recovered, 4.2% of world production. More than half of the research came from Brazil (52.5%), Mexico (16.6%) and Peru (10.5%). 97.6% of the production is co-authored, with a rate of international collaboration of 24.5%. The countries with the highest production in international collaboration are Brazil (39.1%), Peru (26.8%) and Mexico (16%); they are also the countries with the best OutDegree, OutCloseness and Betweenness. The United States (11.9%), United Kingdom (5.8%), France (2.1%), Spain and Switzerland (1.7%), South Africa (1.7%) and Italy (1.6%) are the main collaborators with Latin America.
    CONCLUSION: Brazil, together with Peru and Mexico, is the undisputed leader in Latin American and Caribbean tuberculosis production, due to the volume of articles and its position in the collaborative network. The eradication of tuberculosis requires continuing research in international collaboration, to carry out more effective health policies on tuberculosis.

    Kevin M Klifto, Joseph Mellia, Alexander I Murphy, Fortunay Diatta, John P Fischer, Stephen J Kovach.
      Background Metrics were evaluated between academic plastic surgeons from different tiered training programs to determine promotion predictors within tiers and between tiers for those seeking promotion from assistant professor, associate professor, to full professors. Methodology We performed a retrospective, cross-sectional study by collecting 61 variables from full-time plastic surgery faculty affiliated with United States residency training programs during the 2020-2021 academic year. Surgeons were stratified into nine cohorts for comparison by professorship (assistant, associate, professor) and Doximity-ranked institution program tiers (Tier 1 = T1, Tier 2 = T2, Tier 3 = T3). Univariate followed by multivariate regressions with reciprocal transformation were performed to determine predictors more likely associated with promotion or lateral movement. Results A total of 98 programs listed 851 surgeons. T1/T2/T3 surgeon promotion predictors included more years in practice (p = 0.002; p < 0.001; p < 0.001) and greater number of last-author publications (p < 0.001; p < 0.001; p = 0.007). T1/T3 surgeon promotion predictors included higher h-indexes (p = 0.001; p = 0.002). T1 surgeon promotion predictors included being on journal editorial board (p = 0.040). T2 surgeon promotion predictors from assistant to associate included non-white race (p = 0.010). T3 surgeon promotion predictors included residency director (p = 0.009) and greater number of citations (p = 0.026). Promotion predictors from assistant, associate, and professors for T3/T2/T1 programs included greater number of last-author publications (p = 0.007; p = 0.002; p < 0.001). Movement from assistant and associate between T3/T2/T1 programs included plastic surgery department (p = 0.002; p < 0.001). Movement from assistant between programs included attending Top 10 US News medical schools (p = 0.012), attending more favorable Doximity-ranked research programs (p < 0.001), greater number of first-author publications (p = 0.017), and greater number of citations (p = 0.023). Movement from associate between programs included attending more favorable Doximity-ranked reputation programs (p = 0.017) and higher h-indexes (p = 0.017). Movement from professor between programs included receiving any American Association of Plastic Surgeons (AAPS) award (p = 0.039) and greater number of AAPS awards (p = 0.012). Conclusions Promotion predictors provided evidence to synthesize the Doximity-tiered Promotion Ladder of Academic Plastic Surgery.

    Digital Technologies in the Architecture, Engineering and Construction (AEC) Industry-A Bibliometric-Qualitative Literature Review of Research Activities.
    Bilal Manzoor, Idris Othman, Juan Carlos Pomares.
      Digital technologies (DTs) are proven helpful in the Architecture, Engineering and Construction (AEC) industry due to their varied benefits to project stakeholders, such as enhanced visualization, better data sharing, reduction in building waste, increased productivity, sustainable performance and safety improvement. Therefore, researchers have conducted various studies on DTs in the AEC industry over the year; however, this study explores the state-of-the-art research on DTs in the AEC industry by means of a bibliometric-qualitative review method. This research would uncover new knowledge gaps and practical needs in the domain of DTs in the AEC industry. In addition, bibliometric analysis was carried out by utilizing academic publications from Scopus (i.e., 11,047 publications for the AEC industry, 1956 for DTs and 1778 for DTs in the AEC industry). Furthermore, a qualitative review was further conducted on 200 screened selected research publications in the domain of DTs. This study brings attention to the body of knowledge by envisioning trends and patterns by defining key research interests, journals, countries, new advancements, challenges, negative attitudes and future directions towards DTs in the AEC industry. However, this study is the first in its vital importance and uniqueness by providing a broad updated review of DTs in the AEC literature. Furthermore, this research laid a foundation for future researchers, policy makers and practitioners to explore the limitations in future research.

    The Scientific Value of Abstracts on Prostate Cancer Presented at the European Association of Urology Congresses.
    Jasmin Ataei, Christian Bach, Aida Javan, Thomas-Alexander Vögeli, Christina Grafe, Mohammad Sajjad Rahnama'i.
      Background: Scientific congresses are an important medium for presenting recent clinical findings. Publication of abstracts allows wider dissemination. Objectives: To determine the publication rates of prostate cancer abstracts presented at the annual congress of the European Association of Urology (EAU). Design, Setting, and Participants: All abstracts with the term prostate cancer or carcinoma presented at the congress of the European Association of Urology from 2015 to 2018 were analyzed. We captured their publication rate, journal impact factor and time to publication. Moreover, we formulated a scoring system to determine the grade of discrepancy between the conclusions mentioned in the congress abstract and published abstract. Results: A total of 834 abstracts presented at EAU annual meeting included prostate cancer or carcinoma in their title. We recorded a publication rate of 56.8% with 474 of the 834 abstracts being published with a mean time of 12.5 months. Conclusion: Approximately, 57% of the prostate cancer abstracts presented at the EAU congress are published in peer reviewed journals. This acceptance rate indicates the high distribution and dissemination of these abstracts.

    Demographics of Surgical Specialty Residency Program Directors in the United States: A Cross-sectional Analysis.
    Annika Patel, Adam Burton, Shivani Pandya, Michael Venincasa, Steven J Gedde, Kara M Cavuoto, Divya Sridhar, Amy Kloosterboer, Jayanth Sridhar.
      Objective: To evaluate program director (PD) demographics, training background, and academic productivity in 11 surgical specialties.Summary Background Data: There is currently no comprehensive study comparing educational background, research output, and gender differences between PDs of surgical residencies in the United States.
    Methods: The Accreditation Council for Graduate Medical Education (ACGME) and the Association of American Medical Colleges (AAMC) websites were used to identify residency PDs. Age, information related to service as PD, educational background, and research output were collected utilizing online searches including Doximity, PubMed, and Scopus.. The ACGME Data Resource Book was used to obtain data on the gender makeup of residents in each surgical specialty. Data collection occurred between December 14, 2019, and May 9, 2020.
    Results: 1571 residency PDs across 11 surgical specialties were included. Significant differences between specialties were found with respect to PD gender, current age, age at appointment, years between residency and assignment, term duration, number of PubMed publications, and Scopus h-index. The current age (mean ± SD) ranged from 46.8 ± 8.5 years among Interventional Radiology (IR) PDs to 53.4 ± 9.1 years among Neurological Surgery (NEUROSURG) PDs. The proportion of female PDs ranged from 5.9% in NEUROSURG to 63.5% in Obstetrics and Gynecology (OB-GYN). Completion of a post-residency fellowship was least common for OB-GYN PDs at 9.1%, and most common for IR PDs at 98.8%. The number (mean ± SD) of PubMed publications and Scopus h-index ranged from 13.1 ± 22.3 publications and h index 4.5 ± 5.7 among OB-GYN PDs to 112.5 ± 103.0 publications and h index 27.4 ± 16.7 among Thoracic Surgery PDs. Age and academic productivity as measured by PubMed publications and Scopus h-index were significantly lower among female PDs in multiple surgical specialties.
    Conclusions: There were significant variations in the PDs of surgical specialties, particularly with respect to gender and academic productivity. Efforts should be made to support and encourage greater female representation in the role of surgical residency PD.

    Scholarly Productivity and Rank in Academic Hospital Medicine.
    Andrew Sumarsono, Neil Keshvani, Sameh N Saleh, Nathan Sumarsono, Mindy Tran, Maryam Warsi, Christiana Renner, Eugene S Chu.
      Despite the rapid growth of academic hospital medicine, scholarly productivity remains poorly characterized. In this cross-sectional study, distribution of academic rank and scholarly output of academic hospital medicine faculty are described. We extracted data for 1,554 hospitalists on faculty at the top 25 internal medicine residency programs. Only 11.7% of faculty had reached associate (9.0%) or full professor (2.7%). The median number of publications was 0.0 (interquartile range [IQR], 0.0-4.0), with 51.4% without a single publication. Faculty 6 to 10 years post residency had a median of 1.0 (IQR, 0.0-4.0) publication, with 46.8% of these faculty without a publication. Among men, 54.3% had published at least one manuscript, compared to 42.7% of women (P < .0001). Predictors of promotion included H-index, number of years post residency graduation, completion of chief residency, and graduation from a top 25 medical school. Promotion remains uncommon in academic hospital medicine, which may be partially due to low rates of scholarly productivity.

    Temporal evolution, most influential studies and sleeping beauties of the coronavirus literature.
    Milad Haghani, Pegah Varamini.
      Following the outbreak of SARS-CoV-2 disease, within less than 8 months, the 50 years-old scholarly literature of coronaviruses grew to nearly three times larger than its size prior to 2020. Here, temporal evolution of the coronavirus literature over the last 30 years (N = 43,769) is analysed along with its subdomain of SARS-CoV-2 articles (N = 27,460) and the subdomain of reviews and meta-analytic studies (N = 1027). The analyses are conducted through the lenses of co-citation and bibliographic coupling of documents. (1) Of the N = 1204 review and meta-analytical articles of the coronavirus literature, nearly 88% have been published and indexed during the first 8 months of 2020, marking an unprecedented attention to reviews and meta-analyses in this domain, prompted by the SARS-CoV-2 pandemic. (2) The subset of 2020 SARS-CoV-2 articles is bibliographically distant from the rest of this literature published prior to 2020. Individual articles of the SARS-CoV-2 segment with a bridging role between the two bodies of articles (i.e., before and after 2020) are identifiable. (3) Furthermore, the degree of bibliographic coupling within the 2020 SARS-CoV-2 cluster is much poorer compared to the cluster of articles published prior to 2020. This could, in part, be explained by the higher diversity of topics that are studied in relation to SARS-CoV-2 compared to the literature of coronaviruses published prior to the SARS-CoV-2 disease. (4) The analyses on the subset of SARS-CoV-2 literature identified studies published prior to 2020 that have now proven highly instrumental in the development of various clusters of publications linked to SARS-CoV-2. In particular, the so-called "sleeping beauties" of the coronavirus literature with an awakening in 2020 were identified, i.e., previously published studies of this literature that had remained relatively unnoticed for several years but gained sudden traction in 2020 in the wake of the SARS-CoV-2 outbreak. This work documents the historical development of the literature on coronaviruses as an event-driven literature and as a domain that exhibited, arguably, the most exceptional case of publication burst in the history of science. It also demonstrates how scholarly efforts undertaken during peace time or prior to a disease outbreak could suddenly play a critical role in prevention and mitigation of health disasters caused by new diseases.Supplementary Information: The online version contains supplementary material available at 10.1007/s11192-021-04036-4.

    The American Glaucoma Society 100: Articles with Significant Impact on Clinical Glaucoma Care.
    Kateki Vinod, Steven J Gedde, Pradeep Y Ramulu.
      OBJECTIVE: To identify 100 articles with significant impact on the clinical care of patients with glaucoma.DESIGN: Cross-sectional study.
    PARTICIPANTS: 108 members of the American Glaucoma Society (AGS) in the original survey and 63 in the follow-up survey.
    METHODS: The 100 most frequently cited English-language original articles relevant to glaucoma were identified via a Scopus search. The American Academy of Ophthalmology (AAO) Preferred Practice Pattern Glaucoma Panel selected an additional 100 articles including newer and "classic" papers. An anonymous survey including the list of 200 articles was distributed to the AGS membership. Survey participants were asked to rate the impact of each article on the clinical care of glaucoma patients using a 4-point Likert scale. Survey respondents were able to provide "write-in" suggestions for the AGS 100. A subsequent anonymous follow-up survey was distributed asking participants to use the same Likert scale to rate 31 "write-in" articles suggested in the original survey. The AGS 100 was created by ranking the top 100 articles based on mean Likert scores from the original and follow-up surveys.
    MAIN OUTCOME MEASURES: Original English-language articles that have influenced the clinical care of patients with glaucoma.
    RESULTS: The mean ± standard deviation Likert score of articles included in the AGS 100 was 2.9 ± 0.3 (range, 2.47 - 3.69). The median citation number was 345 (range, 11 - 2426). Publication year ranged from 1965 to 2020. Articles were published in 14 journals, the most common of which were Ophthalmology (42%), American Journal of Ophthalmology (21%), and Archives of Ophthalmology (20%). Forty-eight articles were derived from randomized clinical trials.
    CONCLUSIONS: The AGS 100 is a collection of articles judged to have significant clinical impact on glaucoma care. The list will serve as an online educational resource for ophthalmologists in training and in practice.

      OBJECTIVE: Although the representation of women in science has improved, women remain underrepresented in scientific publications. This study compares women and men in scholarly dissemination through the AMIA Annual Symposium.MATERIALS AND METHODS: Through a retrospective observational study, we analyzed 2017-2020 AMIA submissions for differences in panels, papers, podium abstracts, posters, workshops, and awards for men compared with women. We assigned a label of woman or man to authors and reviewers using Genderize.io, and then compared submission and acceptance rates, performed regression analyses to evaluate the impact of the assumed gender, and performed sentiment analysis of reviewer comments.
    RESULTS: Of the 4687 submissions for which Genderize.io could predict man or woman based on first name, 40% were led by women and 60% were led by men. The acceptance rate was smilar. Although submission and acceptance rates for women increased over the 4 years, women-led podium abstracts, panels, and workshops were underrepresented. Men reviewers increased the odds of rejection. Men provided longer reviews and lower reviewer scores, but women provided reviews that had more positive words.
    DISCUSSION: Overall, our findings reflect significant gains for women in the 4 years of conference data analyzed. However, there remain opportunities to improve representation of women in workshop submissions, panel and podium abstract speakers, and balanced peer reviews. Future analyses could be strengthened by collecting gender directly from authors, including diverse genders such as non-binary.
    CONCLUSION: We found little evidence of major bias against women in submission, acceptance, and awards associated with the AMIA Annual Symposium from 2017 to 2020. Our study is unique because of the analysis of both authors and reviewers. The encouraging findings raise awareness of progress and remaining opportunities in biomedical informatics scientific dissemination.

    Emotional Creativity in Art Education: An Exploratory Analysis and Research Trends.
    Mariana-Daniela González-Zamar, Emilio Abad-Segura.
      The emotions that human beings experience have a key role in the environments in which they operate. In art education, creative processes are influenced by the emotions and experiences lived by the individual, enabling a more emotional and creative design to make life more pleasant. The aim was to examine the research during the period 1917-2020 on the development of emotional creativity in art education. Mathematical and statistical techniques were applied to 984 articles carried from Elsevier's Scopus database. The findings yielded data on the scientific productivity of the journal, authors, research institutions, and countries/territories that promoted this field. The data showed an exponential trend, mostly in the last decade. Five lines of research stand out: emotion, higher education, education, art, and leadership. Moreover, five future research directions related to visual art education, affective paradigm, metacompetency, expressive arts therapy group, and cognitive empathy were detected. This study establishes the link between psychology, neuroscience, and artistic education to constitute the decision-making of the promoters of this topic of research. The analysis of international research allowed us to focus the future publications of academics and researchers, in addition to guaranteeing an adequate approach to the objectives of the institutions and funding centers.

    A scoping review of retracted publications in anesthesiology.
    Marco Fiore, Aniello Alfieri, Maria Caterina Pace, Vittorio Simeon, Paolo Chiodini, Sebastiano Leone, Stefan Wirz, Arturo Cuomo, Vincenzo Stoia, Marco Cascella.
      Context: Fraudulent publication is a scourge of scientific research.Objectives: This scoping review was aimed at characterizing retracted publications for fraud or plagiarism in the field of anesthesia. Does the reputation of the journal (Quartile and Impact Factor, IF) protect the reader from the risk of having the manuscript he read withdrawn for fraud/plagiarism?
    Methods/Design: This scoping review was planned following the Joanna Briggs Institute recommendations. Data sources: PubMed and the Retraction Watch Database (http://retractiondatabase.org/RetractionSearch.aspx?). Study selection: All types of publications retracted. Data extraction: Year, first author nationality, journal name, journal category, IF, Quartile, H index. Data analysis: The association with Quartile and IF was investigated.
    Results: No significant association between retraction of papers published in no-Quartile journals and retractions published in journals placed in the highest quartile.
    Conclusions: The quality of the surveillance in paper submission is not higher in journals of the first Quartile than in journals not placed in other Quartiles. (The protocol was prospectively registered in the Open Science Framework https://doi.org/10.17605/OSF.IO/TGKNE).

    The role and impact of Zootaxa in mammalogy in its first 20 years.
    Pedro Cordeiro-Estrela, Anderson Feijó, Philippe Gaubert, Marcelo Weksler, Lionel Hautier, Paúl M Velazco, Pablo Teta, Pierre-Henri Fabre, Geraldine Veron, Janet K Braun.
      Zootaxa came as a new and innovative publication medium for taxonomy, amidst a scenario of devaluation of this important biological science. After 20 years, it has ascertained itself as one of the main journals in animal taxonomy. However, the contribution of the journal to the taxonomy of Mammalia (mammals), one of the most studied groups of animals with a long-standing, dedicated spectrum of specialized journals (mammalogy), could have been expected as minor. All the current and former editors of the Mammalia section of Zootaxa analyzed the relative contribution of the journal to the description of new species of mammals since 2001. We also analyzed the contribution of Zootaxa by taxon, geographic origin of taxa, and geographic origin of first authors. The taxonomic methodology of authors in species description is described as well as the temporal trends in publications and publication subjects. We highlight the editors' picks and eventually, the challenges for the future. We found that Zootaxa has had a significant contribution to mammalogy, being the second journal (the first being Journal of Mammalogy) in terms of number of new species described (76; 10.6% of the new mammalian species described between 2001 and 2020). The majority of the new species were described following an integrative taxonomic approach with at least two sources of data (86%). The analysis of published taxa, their geographic origin, and the country of origin of first authors shows a wide coverage and exhaustive representation, except for the species from the Nearctic. We conclude that Zootaxa has likely responded to a repressed demand for an additional taxonomic journal in mammalogy, with as possible appeals the absence of publication fees and an established publication speed. With 246 articles published in the past 20 years, the Mammalia section of Zootaxa embraces a large spectrum of systematic subjects going beyond alpha taxonomy. The challenges for the future are to encourage publications of authors from the African continent, still poorly represented, and from the palaeontology community, as the journal has been open to palaeontology since its early days.

    What difference might retractions make? An estimate of the potential epistemic cost of retractions on meta-analyses.
    Daniele Fanelli, Julie Wong, David Moher.
      The extent to which a retraction might require revising previous scientific estimates and beliefs - which we define as the epistemic cost - is unknown. We collected a sample of 229 meta-analyses published between 2013 and 2016 that had cited a retracted study, assessed whether this study was included in the meta-analytic estimate and, if so, re-calculated the summary effect size without it.The majority (68% of N=229) of retractions had occurred at least one year prior to the publication of the citing meta-analysis. In 53% of these avoidable citations, the retracted study was cited as a candidate for inclusion, and only in 34% of these meta-analyses (13% of total) the study was explicitly excluded because it had been retracted. Meta-analyses that included retracted studies were published in journals with significantly lower impact factor. Summary estimates without the retracted study were lower than the original if the retraction was due to issues with data or results and higher otherwise, but the effect was small.We conclude that meta-analyses cite retracted articles to similar rates than other types of study and have a problematically high probability of including them in their pooled summaries, butt the overall epistemic cost is contained.

    Harvestmen in the first twenty years: a scientometric analysis of Zootaxa's contribution to opilionology (Arthropoda, Arachnida, Opiliones).
    Abel P Rez-González, Luis E Acosta, Daniel N Proud, Jeffrey W Shultz.
      In its first twenty years of existence Zootaxa has been widely utilized among researchers of Opiliones, mainly those coming from Latin American countries, principally Brazil. During 20032020, a total of 141 papers on Opiliones were published in Zootaxa (no papers were published on Opiliones in the first two years, 20012002). The journal has greatly facilitated the dissemination of knowledge on Opiliones, especially with respect to the taxonomy and systematics of harvestmen from the Neotropical Realm. Those 141 papers in Zootaxa include almost a quarter (191) of the new species of Opiliones described between 2001 and 2020, as well as 112 new synonymies. Additionally, 27 of those papers proposed 182 new or restored combinations. A total of 108 authors working in 25 countries have contributed papers to Zootaxa focusing on Opiliones. There is clearly a predominance for collaborative contributions with more than twice as many papers authored by two or more authors compared to single-author publications. In general, the majority of papers deal within the local biogeographic realm (where the lead author resides). Studies of harvestmen from seven of the eight biogeographic realms were published in Zootaxa during 20032020. The largest portion of these contributions were by far focused on the Neotropical opiliofauna, but Australasian, Nearctic, Indomalayan, Palearctic, Afrotropical and Antarctic opiliofauna are covered as well. No papers on Opiliones have been published in Zootaxa by authors representing countries in Africa. We also recognize a strong gender bias in authorship and the current composition of Opiliones subject editors. We will strive to create an inclusive environment and aim to promote diversity of scientists who study Opiliones.

    Sex Differences in Academic Productivity Across Academic Ranks and Specialties in Academic Medicine: A Systematic Review and Meta-analysis.
    Giang L Ha, Eric J Lehrer, Ming Wang, Emma Holliday, Reshma Jagsi, Nicholas G Zaorsky.
      Importance: Despite equal numbers of men and women entering medical school, women are underrepresented in the upper echelons of academic medicine and receive less compensation and research funding. Citation-related publication productivity metrics, such as the h-index, are increasingly used for hiring, salary, grants, retention, promotion, and tenure decisions. Exploring sex differences in these metrics across academic medicine provides deeper insight into why differences are observed in career outcomes.Objective: To systematically examine the available literature on sex differences in h-index of academic faculty physicians across all medical specialties and all levels of academic rank.
    Data Sources: Medical literature with the term h-index found in PubMed and published between January 1, 2009, and December 31, 2018, was used.
    Study Selection: A PICOS (Population, Intervention, Comparison, and Outcomes), PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses), and MOOSE (Meta-analysis of Observational Studies in Epidemiology) selection protocol was used to find observational studies that published h-indexes for faculty physicians that were stratified by sex. Studies were excluded if they were review articles, retracted, or unavailable online. Ultimately, 14 of 786 studies (1.78%) met the inclusion criteria.
    Data Extraction and Synthesis: Data from 9 studies across 16 specialties were examined using weighted random-effects meta-analyses. Five studies were excluded because of overlapping specialties with another study or because they were missing appropriate statistics for the meta-analysis. Four of these studies were included in qualitative synthesis to bring the total to 13 studies.
    Main Outcomes and Measures: The primary study outcome was the h-index.
    Results: The meta-analysis included 10 665 North American unique academic physicians across 9 different studies from the years 2009 to 2018. Of the 10 665 physicians, 2655 (24.89%) were women. Summary effect sizes for mean h-indexes of men and women and mean h-index difference between men and women were determined for all faculty physicians and at each academic rank. Overall, female faculty had lower h-indexes than male faculty (mean difference, -4.09; 95% CI, -5.44 to -2.73; P < .001). When adjusting for academic rank, female faculty still had lower h-indexes than male faculty at the ranks of assistant professor (mean difference, -1.3; 95% CI, -1.90 to -0.72; P < .001), associate professor (mean difference, -2.09; 95% CI, -3.40 to -0.78; P = .002), and professor (mean difference, -3.41; 95% CI, -6.24 to -0.58; P = .02).
    Conclusions and Relevance: In this systematic review and meta-analysis, women had lower h-indexes than men across most specialties and at all academic ranks, but it is unclear why these differences exist. These findings suggest that future investigation should be conducted regarding the causes of lower h-indexes in women and that interventions should be developed to provide a more equitable environment for all physicians regardless of sex.

    Measuring novelty in science with word embedding.
    Sotaro Shibayama, Deyun Yin, Kuniko Matsumoto.
      Novelty is a core value in science, and a reliable measurement of novelty is crucial. This study proposes a new approach of measuring the novelty of scientific articles based on both citation data and text data. The proposed approach considers an article to be novel if it cites a combination of semantically distant references. To this end, we first assign a word embedding-a vector representation of each vocabulary-to each cited reference on the basis of text information included in the reference. With these vectors, a distance between every pair of references is computed. Finally, the novelty of a focal document is evaluated by summarizing the distances between all references. The approach draws on limited text information (the titles of references) and publicly shared library for word embeddings, which minimizes the requirement of data access and computational cost. We share the code, with which one can compute the novelty score of a document of interest only by having the focal document's reference list. We validate the proposed measure through three exercises. First, we confirm that word embeddings can be used to quantify semantic distances between documents by comparing with an established bibliometric distance measure. Second, we confirm the criterion-related validity of the proposed novelty measure with self-reported novelty scores collected from a questionnaire survey. Finally, as novelty is known to be correlated with future citation impact, we confirm that the proposed measure can predict future citation.

    Mining Proteome Research Reports: A Bird's Eye View.
    Jagajjit Sahu.
      The complexity of data has burgeoned to such an extent that scientists of every realm are encountering the incessant challenge of data management. Modern-day analytical approaches with the help of free source tools and programming languages have facilitated access to the context of the various domains as well as specific works reported. Here, with this article, an attempt has been made to provide a systematic analysis of all the available reports at PubMed on Proteome using text mining. The work is comprised of scientometrics as well as information extraction to provide the publication trends as well as frequent keywords, bioconcepts and most importantly gene-gene co-occurrence network. Out of 33,028 PMIDs collected initially, the segregation of 24,350 articles under 28 Medical Subject Headings (MeSH) was analyzed and plotted. Keyword link network and density visualizations were provided for the top 1000 frequent Mesh keywords. PubTator was used, and 322,026 bioconcepts were able to extracted under 10 classes (such as Gene, Disease, CellLine, etc.). Co-occurrence networks were constructed for PMID-bioconcept as well as bioconcept-bioconcept associations. Further, for creation of subnetwork with respect to gene-gene co-occurrence, a total of 11,100 unique genes participated with mTOR and AKT showing the highest (64) number of connections. The gene p53 was the most popular one in the network in accordance with both the degree and weighted degree centrality, which were 425 and 1414, respectively. The present piece of study is an amalgam of bibliometrics and scientific data mining methods looking deeper into the whole scale analysis of available literature on proteome.

    Trends in Nursing Research on Infections: Semantic Network Analysis and Topic Modeling.
    Jongsoon Won, Kyunghee Kim, Kyeong-Yae Sohng, Sung-Ok Chang, Seung-Kyo Chaung, Min-Jung Choi, Youngji Kim.
      BACKGROUND: Many countries around the world are currently threatened by the COVID-19 pandemic, and nurses are facing increasing responsibilities and work demands related to infection control. To establish a developmental strategy for infection control, it is important to analyze, understand, or visualize the accumulated data gathered from research in the field of nursing.METHODS: A total of 4854 articles published between 1978 and 2017 were retrieved from the Web of Science. Abstracts from these articles were extracted, and network analysis was conducted using the semantic network module.
    RESULTS: 'wound', 'injury', 'breast', "dressing", 'temperature', 'drainage', 'diabetes', 'abscess', and 'cleaning' were identified as the keywords with high values of degree centrality, betweenness centrality, and closeness centrality; hence, they were determined to be influential in the network. The major topics were 'PLWH' (people living with HIV), 'pregnancy', and 'STI' (sexually transmitted infection).
    CONCLUSIONS: Diverse infection research has been conducted on the topics of blood-borne infections, sexually transmitted infections, respiratory infections, urinary tract infections, and bacterial infections. STIs (including HIV), pregnancy, and bacterial infections have been the focus of particularly intense research by nursing researchers. More research on viral infections, urinary tract infections, immune topic, and hospital-acquired infections will be needed.

    Scientometric Analysis and Systematic Review of Multi-Material Additive Manufacturing of Polymers.
    Yufan Zheng, Wenkang Zhang, David Moises Baca Lopez, Rafiq Ahmad.
      Multi-material additive manufacturing of polymers has experienced a remarkable increase in interest over the last 20 years. This technology can rapidly design and directly fabricate three-dimensional (3D) parts with multiple materials without complicating manufacturing processes. This research aims to obtain a comprehensive and in-depth understanding of the current state of research and reveal challenges and opportunities for future research in the area. To achieve the goal, this study conducts a scientometric analysis and a systematic review of the global research published from 2000 to 2021 on multi-material additive manufacturing of polymers. In the scientometric analysis, a total of 2512 journal papers from the Scopus database were analyzed by evaluating the number of publications, literature coupling, keyword co-occurrence, authorship, and countries/regions activities. By doing so, the main research frame, articles, and topics of this research field were quantitatively determined. Subsequently, an in-depth systematic review is proposed to provide insight into recent advances in multi-material additive manufacturing of polymers in the aspect of technologies and applications, respectively. From the scientometric analysis, a heavy bias was found towards studying materials in this field but also a lack of focus on developing technologies. The future trend is proposed by the systematic review and is discussed in the directions of interfacial bonding strength, printing efficiency, and microscale/nanoscale multi-material 3D printing. This study contributes by providing knowledge for practitioners and researchers to understand the state of the art of multi-material additive manufacturing of polymers and expose its research needs, which can serve both academia and industry.

    Publication patterns' changes due to the COVID-19 pandemic: a longitudinal and short-term scientometric analysis.
    Shir Aviv-Reuven, Ariel Rosenfeld.
      In recent months the COVID-19 (also known as SARS-CoV-2 and Coronavirus) pandemic has spread throughout the world. In parallel, extensive scholarly research regarding various aspects of the pandemic has been published. In this work, we analyse the changes in biomedical publishing patterns due to the pandemic. We study the changes in the volume of publications in both peer reviewed journals and preprint servers, average time to acceptance of papers submitted to biomedical journals, international (co-)authorship of these papers (expressed by diversity and volume), and the possible association between journal metrics and said changes. We study these possible changes using two approaches: a short-term analysis through which changes during the first six months of the outbreak are examined for both COVID-19 related papers and non-COVID-19 related papers; and a longitudinal approach through which changes are examined in comparison to the previous four years. Our results show that the pandemic has so far had a tremendous effect on all examined accounts of scholarly publications: A sharp increase in publication volume has been witnessed and it can be almost entirely attributed to the pandemic; a significantly faster mean time to acceptance for COVID-19 papers is apparent, and it has (partially) come at the expense of non-COVID-19 papers; and a significant reduction in international collaboration for COVID-19 papers has also been identified. As the pandemic continues to spread, these changes may cause a slow down in research in non-COVID-19 biomedical fields and bring about a lower rate of international collaboration.

    The trends of dental biomaterials research and future directions: A mapping review.
    Sundus Iftikhar, Noureen Jahanzeb, Mehvish Saleem, Shafiq Ur Rehman, Jukka Pekka Matinlinna, Abdul Samad Khan.
      Objective: This literature research aimed to compare, contrast and quantify the innovations in the most commonly used dental biomaterials.Methodology: Original research articles based on experimental dental biomaterials published between 2007 and 2019 were retrieved and reviewed. A search of electronic databases, PubMed, Scopus, and Web of Science indexed dental/biomaterials journals, has been conducted. The inclusion criteria in this research were: synthesis of experimental dental materials, whereas commercial dental materials, review articles, and clinical trials (case reports) were excluded.
    Results: It was found that the amount of publications related to dental subgingival implants, computer-aided modeling ceramics, aesthetic restorative materials, adhesives cements, ceramics, bioceramics, endodontic materials, bioactive scaffolds, stem cells, and guided-tissue membranes had increased significantly from 2007. At the same time, the number of publications related to dental cements, silver amalgam, and dental alloys has decreased. For characterization of dental materials it was noted that mechanical properties were tested mostly for restorative materials. On the other hand, biological properties were most assessed for dental subgingival implants and endodontic materials, however, physical properties predominantly for bioceramics.
    Conclusion: It is concluded that to meet clinical demands there was more focus on restorative materials that provided better aesthetics, including resin composites, adhesive resin composites (luting cements), zirconia, and other ceramics. The boost in laboratory and animal research related to bioceramics was attributed to their regenerative potential. This current literature study will help growing researchers to consider and judge the direction to which research might be guided in order to plan prospective research projects.

    Independent or Integrated Plastic Surgery Residency Pathways: Trends in Representation in Academic Plastic Surgery in the United States.
    Sarah P Erpenbeck, Samyd S Bustos, Brandon T Smith, Francesco M Egro, Vu T Nguyen.
      INTRODUCTION: The training pathway for plastic surgery has evolved in recent years with the adoption and rise in popularity of the integrated model. Studies have demonstrated that there may be differences between integrated graduates and independent graduates, specifically in career choices and type of practice. This study seeks to understand if there are differences in representation at academic and leadership positions between graduates of the 2 pathways.METHODS: A cross-sectional study was conducted in June of 2018 to assess integrated and independent pathway graduate's representation in academic plastic surgery in the United States. Factors examined were career qualifications, academic productivity, faculty positions, and influence of pathway on career advancement.
    RESULTS: A total of 924 academic plastic surgeons were analyzed, 203 (22.0%) of whom were integrated graduates and 721 (78.0%) of whom were independent graduates. Independent graduates had greater National Institutes of Health funding (integrated, $40,802; independent, $257,428; P = 0.0043), higher h-index (integrated, 7.0; independent, 10.0; P < 0.001), and higher publication number (integrated, 17; independent, 25; P = 0.0011). Integrated graduates were more likely to be assistant professors (integrated, 70%; independent, 40.7%; P < 0.001) and required a shorter postresidency time to reach all positions examined compared with independent graduates.
    CONCLUSIONS: Residency training pathway influences academic plastic surgeons in research output, qualifications, and academic positions. This is likely due to the relatively new nature of the integrated program compared with the independent, as well as the shorter length of training for integrated graduates. However, trends are moving toward integrated graduates showing increased interest and productivity in academic medicine.

    Disparity in Gender Representation of Speakers at National Emergency Medical Services Conferences: A Current Assessment and Proposed Path Forward.
    Alexandra Davic, Erin Carey, Erin Lambert, Therese Luckingham, Nikki Mongiello, Randi Peralta, Nicolina Puccio, Kimberly Rivera, Kirsten Torre, Lauren M Maloney.
      INTRODUCTION: Gender disparities between Emergency Medicine physicians with regards to salary, promotion, and scholarly recognition as national conference speakers have been well-documented. However, little is known if similar gender disparities impact their out-of-hospital Emergency Medical Services (EMS) colleagues. Although there have been improvements in the ratio of women entering the EMS workforce, gender representation has improved at a slower rate for paramedics compared to emergency medical technicians (EMTs). Since recruitment, retention, and advancement of females within a specialty have been associated with the visibility of prominent, respected female leaders, gender disparity of these leaders as national conference speakers may contribute to the "leaky pipeline effect" seen within the EMS profession. Gender representation of these speakers has yet to be described objectively.STUDY OBJECTIVE: The primary objective of this study was to determine if disparity exists in gender representation of speakers at well-known national EMS conferences and trade shows in the United States (US) from 2016-2020. The secondary objective was to determine if males were more likely than females to return to a conference as a speaker in subsequent years.
    METHODS: A cross-sectional analysis of programs from well-known national conferences, specifically for EMS providers, which were held in the US from 2016-2020 was performed. Programs were abstracted for type of conference session (pre-conference, keynote, main conference) and speakers' names. Speaker gender (male, female) was confirmed via internet search.
    RESULTS: Seventeen conference programs were obtained with 1,709 conference sessions that had a total of 2,731 listed speaker names, of whom 537 (20%) were female. A total of 30 keynote addresses had 39 listed speaker names of whom six (15%) were female. No significant difference was observed in the number of years males returned to present at the same conference as compared to females.
    CONCLUSION: Gender representation of speakers at national EMS conferences in the US is not reflective of the current best estimate of the US EMS workforce. This disparity exists not only in the overall percent of female names listed as speakers, but also in the percent of individual female speakers, and is most pronounced within keynote speakers. Online lecture platforms, as an unintentional consequent of the COVID-19 pandemic, coupled with intentional speaker development and mentorship initiatives, may reduce barriers to facilitating a new pipeline for more females to become speakers at national EMS conferences.

    Scientific Cooperation and the Co-production of Scientific Outcomes for Physical Activity Promotion: Results From a Transdisciplinary Research Consortium.
    Susanne Ferschl, Maike Till, Karim Abu-Omar, Klaus Pfeifer, Peter Gelius.
      Background: To tackle complex societal challenges such as the high prevalence of physical inactivity, research funding is increasingly channeled toward cross-disciplinary research consortia. This study focused on exchange and cooperation (E&C) among the scientists of a 5-year transdisciplinary research initiative in Germany. Researchers' perceptions of E&C were combined with numbers of collaborative products during the project's life to make the developments of E&C and the quality of collaborative products visible. Methods: We applied a mixed-methods design including a qualitative content analysis of pre-interviews, focus-group interviews, and documents as well as a quantitative analysis of research (scientific publications, books, conference participations) and training outcomes (supervised bachelor's, master's, and Ph.D. theses). Inductive and deductive approaches were combined to analyze factors of collaborative readiness and to identify perceptions of E&C among project teams. Based on Hall et al.'s "Conceptual Model for Evaluation of Collaborative Initiatives," the project period was separated into phases of "collaborative readiness," "collaborative capacity," and "collaborative products." Results: Our findings revealed a discrepancy between the objectively assessed concepts of collaborative readiness and researchers' reported perceptions of E&C during the early project stage. A set of E&C hindering factors identified during the initial project phase remained present until the final project stage. Further, E&C among scientists increased over time, as reflected by researchers' perceptions. Reports of scientists also showed that outcomes were co-produced at the final project stage for the first time, while knowledge integration had not yet been achieved. Generally, the number of collaborative products (particularly scientific publications) also substantially increased over time. E&C was supported and promoted by the efforts of the coordinating sub-project. Conclusion: Scientific E&C is a learning process and needs time to develop. A participatory research approach taking into account the perspectives on and requirements for E&C during the project's design might lay the ground for suitable, supportive, and transparent conditions for effective and successful E&C. Despite their time- and resource-consuming nature, cross-disciplinary research initiatives provide a fertile context in which to generate new solutions for pressing societal issues given that long-term funding and the establishment of an overarching coordination organ is assured.

    What is the Trend in Representation of Women and Under-represented Minorities in Orthopaedic Surgery Residency?
    Max R Haffner, Benjamin W Van, Joseph B Wick, Hai V Le.
      BACKGROUND: Orthopaedic surgery training programs have lagged behind other surgical specialties in increasing their representation of women and people from under-represented minority (URM) groups. Comparative data between orthopaedic surgery and other specialties are needed to help identify solutions to closing the diversity gap.QUESTIONS/PURPOSES: (1) Which surgical specialties have the greatest representation of women residents and residents from URM groups? (2) How have the proportions of women residents and residents from URM groups changed across the surgical specialties during the past decade?
    METHODS: This was a retrospective evaluation of a large, longitudinally maintained survey database. Resident data by gender and ethnicity were retrieved from the Accreditation Council for Graduate Medical Education Data Resource Books for the 2011 to 2012 through 2019 to 2020 academic years. The Accreditation Council for Graduate Medical Education database is updated annually; thus, it is the most up-to-date and complete database available for gender and ethnicity data for all surgical residents. Data were obtained and analyzed for seven different surgical specialties: orthopaedic surgery, neurosurgery, ophthalmology, otolaryngology, plastic surgery, general surgery, and urology. No sampling was necessary, and thus descriptive statistics of the data were completed. Because the entire population of residents was included for the period of time in question, no statistical comparisons were made, and the reported differences represent absolute differences between the groups for these periods. Linear regression analyses were performed to estimate the annual growth rates of women residents and residents from URM groups in each specialty.
    RESULTS: Among the seven surgical specialties, representation of women residents increased from 28% (4640 of 16,854) or residents in 2012 to 33% (6879 of 20,788) in 2020. Orthopaedic surgery had the lowest representation of women residents every year, with women residents comprising 16% of residents (700 of 4342) in 2020. Among the seven surgical specialties, representation of residents from URM groups increased from 8.1% (1362 of 16,854) in 2012 to 9.7% (2013 of 20,788) in 2020. In 2020, the representation of residents from URM groups in orthopaedic surgery was 7.7% (333 of 4342). In 2020, general surgery had the highest representation of women residents (42%; 3696 of 8809) as well as residents from URM groups (12%; 1065 of 8809). Plastic surgery (1.46% per year) and general surgery (0.95% per year) had larger annual growth rates of women residents than the other specialties did. In each surgical specialty, the annual growth rate of residents from URM groups was insignificant.
    CONCLUSION: During the past decade, there was only a small increase in the representation of women in orthopaedic surgery, while the representation of people from URM groups did not change. In contrast, by 2020, general surgery had become the most diverse among the seven surgical specialties. To increase diversity in our field, we need to evaluate and implement some of the effective interventions that have helped general surgery become the diverse surgical specialty that it is today.
    CLINICAL RELEVANCE: General surgery has substantially reduced gender and ethnic disparities that existed in the past, while those in orthopaedic surgery still persist. General surgery residencies have implemented a holistic review of resident applications and longitudinal mentoring programs to successfully address these disparities. Orthopaedic surgery programs should consider placing less emphasis on United States Medical Licensing Examination score thresholds and more weight on applicants' non-academic attributes, and put more efforts into targeted longitudinal mentorship programs, some of which should be led by non-minority faculty.
