      INTRODUCTION: This study aimed to identify and analyze the 100 most-cited articles published in orthodontic scientific journals in the past 21 years.METHODS: The research was conducted in the Thomson Reuters Web of Science data citation index, considering articles from 2000 to 2020 and the category of dentistry, oral surgery, and medicine. Information about the number of citations, citations per year, title, authors, year of publication, the title of scientific journals, type of study, keywords, and thematic field were extracted for each article. Descriptive statistical analyses were performed to evaluate the collected data. The Pearson correlation analysis was used to explore the relationship between publication and the number of citations received. The VOSviewer software (Leiden University Center for Science and Technology Studies, Leiden, the Netherlands) was used to generate the keyword cooccurrence network.
    RESULTS: The number of citations of the 100 selected articles ranged from 122 to 547. The journal with the largest number of cited articles was the American Journal of Orthodontics and Dentofacial Orthopedics. Most of the papers were cross-sectional and longitudinal studies, and the most frequent thematic fields among the selected articles were anchorage, root resorption, and rapid maxillary expansion. Orthodontic treatment, anchorage, and root resorption were the most frequent keywords.
    CONCLUSIONS: Bibliometric analysis of citations revealed a greater centralization of orthodontic studies. Most of the articles were published in a single journal and by one country. Anchorage is a trending topic in orthodontics, and cross-sectional and longitudinal studies are the most-cited types of papers.

    Decades on emergency decision-making: a bibliometric analysis and literature review.
    Lin-Xiu Hou, Ling-Xiang Mao, Hu-Chen Liu, Ling Zhang.
      When an emergency occurs, effective decisions should be made in a limited time to reduce the casualties and economic losses as much as possible. In the past decades, emergency decision-making (EDM) has become a research hotspot and a lot of studies have been conducted for better managing emergency events under tight time constraint. However, there is a lack of a comprehensive bibliometric analysis of the literature on this topic. The objective of this paper is to provide academic community with a complete bibliometric analysis of the EDM researches to generate a global picture of developments, focus areas, and trends in the field. A total of 303 journal publications published between 2010 and 2020 were identified and analyzed using the VOSviewer in regard to cooperation network, co-citation network, and keyword co-occurrence network. The findings indicate that the annual publications in this research field have increased rapidly since 2014. Based on the cooperation network and co-citation network analyses, the most productive and influential countries, institutions, researchers, and their cooperation networks were identified. Using the co-citation network analysis, the landmark articles and the core journals in the EDM area are found out. With the help of the keyword co-occurrence network analysis, research hotspots and development of the EDM domain are determined. According to current trends and blind spots in the literature, possible directions for further investigation are finally suggested for EDM. The literature review results provide valuable information and new insights for both scholars and practitioners to grasp the current situation, hotspots and future research agenda of the EDM field.

    Global Trends in Intertrochanteric Hip Fracture Research From 2001 to 2020: A Bibliometric and Visualized Study.
    Ze Zhang, Yudian Qiu, Yawen Zhang, Yi Zhu, Fengpo Sun, Junchuan Liu, Tongyi Zhang, Liangyuan Wen.
      Background: Intertrochanteric femur fractures, which are common geriatric osteoporotic fractures, have imposed a huge economic and social burden. This study clarified the global status of research on intertrochanteric fractures between 2001 and 2020 and predicted future research trends in this field using bibliometric and visualized studies. Methods: Publications related to intertrochanteric fractures were retrieved from the Web of Science (WoS) database. All studies were published between 2001 and 2020. Bibliometric and co-occurrence analyses were conducted using VoS viewer software. Results: In total, 2,632 studies were retrieved. The number of global publications regarding intertrochanteric fractures increased annually. The United States was the largest contributor, ranking first in total publications, citations, and the H-index. Switzerland had the highest average citation frequency among the 10 countries with the highest number of publications. The journal that published the most articles regarding intertrochanteric fractures was the Injury International Journal of The Care of The Injured, with 290 articles published. This journal also ranked first in the citation frequency. MJ Parker, an author, published the most papers in the field, and the University of California research team at San Francisco contributed the most publications in this field. During the co-occurrence analysis, all keywords were divided into four clusters: internal fixation study, complication study, risk-factor study, and survival and prognosis analysis study. The internal fixation and survival and prognosis analysis studies were predicted as the next hot topics in the field of intertrochanteric fractures. Conclusions: Intertrochanteric fractures are gaining increasing research attention according to the current global trend, and the number of publications regarding intertrochanteric hip fractures will continue to increase. The United States currently publishes the most articles on intertrochanteric fractures. The number of studies related to internal fixation, survival, and prognosis analysis is increasing, suggesting that these topics may become the next research hotspots in the area of intertrochanteric fractures.

    The Top 100 Most Cited Articles on Intrauterine Adhesion: a Bibliometric Analysis.
    Pan Gu, Waixing Li, Xingping Zhao, Dabao Xu.
      Bibliometric analysis is a statistical method that attempts to assess articles by their citations, analyzing their frequency and citation pattern, which subsequently gleans direction and guidance for future research. Over the past few years, articles focused on intrauterine adhesions have been published with increasing frequency. Nevertheless, little is known about the properties and qualities of this research, and no current analysis exists that has examined the progress in intrauterine adhesion research. Web of Science Core Collection, BIOSIS Citation Index, and MEDLINE database were searched to identify articles on intrauterine adhesion published from 1950 to October 2020. The 100 most cited articles were chosen to analyze citation count, citation density, authorship, theme, geographic distribution, time-related flux, level of evidence, and network analysis. An overwhelming majority of these 100 articles were published in the 2010s (35%). Citations per article ranged from 30 to 253. Chinese authors published the most papers in the top 100, followed by the USA, France, Israel, and Italy. The most salient study themes included operative hysteroscopy and adjunctive treatments for improving reproductive outcomes. The most common level of evidence was level II, and there was no statistical difference in the number of citations between the levels. The network analysis indicated that hysteroscopy, hysteroscopic adhesiolysis, infertility, and the reproductive outcome had a great degree of centrality in the 2000s and 2010s. In comparison, placental implantation had a great degree of centrality in the 2000s, and stem cell and fibrosis had a great degree of centrality in the 2010s. The value of IUA investigation has been gradually appreciated recently. Hysteroscopic adhesiolysis was continuously explored to achieve better reproductive outcome. Over time, the main focus of research has gradually shifted from complications to postoperative adjuvant treatment. Moreover, breakthrough progress is needed in underlying mechanism and early prevention of IUA.

    Developments, focuses, and trends in early-onset scoliosis from 2005 to 2020: A systematic bibliometric analysis.
    Ziyang Liu, Kang Gao, Yong Hai, Tie Liu.
      OBJECTIVE: Although several studies have been published on early-onset scoliosis (EOS), bibliometric analysis is still lacking. The systematic bibliometric analysis enables researchers to understand the scope of research topics, identify research focuses and key literature, and predict future research directions.METHODS: Literature data were retrieved from the Web of Science Core Collection database. Web of Science's Results Analysis and Citation Report were used to analyze the published literature in different views. CiteSpace and VOSviewer were used for further analysis, including cooperation network analysis of authors, institutions, countries/regions, discipline, and journal analysis, reference co-citation analysis, and keyword co-occurrence analysis.
    RESULTS: The final analysis included 674 relevant papers published between 2005 and 2020. From 2005 to 2020, the field of EOS has expanded rapidly. There is multiple cooperation among authors, institutions, and countries/regions, with some making great contributions. The results of reference co-citation analysis show that studies have several main focuses, including growing rod (GR), magnetically controlled growing rod (MCGR), an early-onset scoliosis 24-item questionnaire (EOSQ-24), and growth evaluation.
    CONCLUSIONS: From 2005 to 2020, surgical treatment has remained the focus of research in the EOS field. MCGR is the latest research focus, which may become more comprehensive in the future. GR remains the most popular topic, and potential new surgical techniques may need to improve to become the favored ones. Besides, assessing the health-related quality of life (HRQOL) status and growth parameters of EOS patients have become a popular topic.

    Haroon
      Introduction: Every year, millions of children die from preventable causes worldwide. According to World Health Organization, injuries are the leading cause of disability and death among all age groups below 60 years. Aim: This study aimed to evaluate the global research outcomes and trends, and some key bibliometric indicators in pediatric trauma. Methods: A descriptive bibliometric analysis study was designed. On June 14, 2021, an electronic search was performed in the Web of Science Core Collection database using the potential searching keywords "Pediatric AND Trauma" in the title field without any limitations. The search was performed using the Boolean search query method. The data were downloaded in plaintext and comma-separated values format. The required graphs were generated using OriginPro 2018. Furthermore, the data were transferred to HistCite™ software for bibliometric analysis. In addition, the obtained data were plotted for network visualization mapping using VOSviewer software version 1.6.15 for windows. Results: A total of 2,269 documents were included in the final analysis. The included documents were authored by 7,894 authors and published in 395 research and academic journals, mainly in the English language (n = 2,222). The main document types were articles (n = 1,276, citations = 18,244), and meeting abstracts (n = 331, citations = 19). Pediatric (n = 2,269) and trauma (n = 2,257) were the most widely used keywords. The most productive year was 2019 (n = 184, citations = 527). The most prolific author was Upperman JS (n = 29, citations = 202). The most attractive journals in pediatric trauma research were The Journal of Trauma and Acute Care Surgery (n = 290, citations = 5,199) and the Journal of Pediatric Surgery (n = 256, citations = 5,088). The most active institute was the University of California System (n = 110). The most dominant country was the United States of America (USA) (n = 1,620, citations = 22,983). The USA and Canada had the highest total link strength, 103 and 70, respectively. Conclusion: This study provides a comprehensive overview of research output in pediatric trauma. The USA continues to dominate scientific research and funding in pediatric trauma. Findings of the current study will help the researchers and clinicians to understand the recent achievements and research frontiers. Collaborative research initiative needs to be established between institutions in developed and developing countries and among researchers.

    The global status of research in breast cancer liver metastasis: a bibliometric and visualized analysis.
    Yanlong Shi, Wei Wei, Li Li, Qian Wei, Fei Jiang, Guozhi Xia, Hongzhu Yu.
      This study aimed to investigate the distribution laws and research frontiers of international literature, so as to present a holistic bibliometric evaluation of the studies on breast cancer liver metastasis(BCLM). Data were collected from the Web of Science Core Collection database, including publications, year, country, journal, author and keywords. The software VOSviewer and CiteSpace were used for bibliometric coupling, co-authorship, co-citation and co-occurrence analysis. In total, 1,031 publications were analyzed from 2004 to 2020 on BCLM. The year with the highest number of publications was 2006, with 103 papers. The United States, followed by China and Germany were the leading countries on BCLM, accounting for 59% of the whole. The journals that published about BCLM were mainly located in Q1/Q2. Keywords co-occurrence analysis divides BCLM into five clusters:"basic research", "auxiliary diagnosis and therapy", "liver resection", "clinical trial" and "prognosis". Main treatment therapies were the latest focus. Burst detection indicated that the trends in BCLM concentrated on subtype and SEER. There is apparently brighter perspective for BCLM research in the coming years, especially in liver resection, subtype and bioinformatics. The consequence of our study as the exclusive scientific evaluation offered an integral overview of BCLM, particularly for research focus and future directions, which can further accurately guide scholars on diagnosis, treatment, and personalized prevention.

    On the social and conceptual structure of the 50-year research landscape in entrepreneurial finance.
    Minh-Hoang Nguyen, Thanh-Hang Pham, Manh-Toan Ho, Huyen Thanh T Nguyen, Quan-Hoang Vuong.
      In recent decades, drastic changes in global social-economic situations have led to significant shifts in the financial market for entrepreneurial firms, thus resulting in changes in entrepreneurial finance discipline. The current body of literature, despite its significant growth, has not provided an overview landscape of this research area. Consequently, this study aims to fill this gap by employing the bibliometric analysis of 6902 articles from 1970 to 2019 extracted from the Web of Science database. By doing so, this paper attempts to provide an overview of the discipline's research output, social and conceptual structure, and offer strategies facilitating the scientific development within the field. The findings indicate that entrepreneurial finance is a young and growing field with an exponential increase in the number of publications (approx. 19.75 percent per year) and rising collaboration tendency among authors. The 1991-2000 period is a crucial milestone of the field thanks to the remarkable growth and impact of studies during this period as well as simultaneously occurring historical events. We also notice a sign of Western ideological homogeneity from the collaboration networks and lists of most productive authors, institutions, and countries. Additionally, using thematic mapping, five major research domains are identified: "venture capital", "crowdfunding", "SMEs finance", "social entrepreneurship finance", "IPO and corporate governance". Based on these findings, we raise the concern of lacking diversity in entrepreneurial finance research and propose strategies for authors, journals, and policymakers to diversify the literature.

    Forty Years of Risk Analysis: A Scientometric Overview.
    Floris Goerlandt, Jie Li.
      Risk Analysis was first published in 1981, established with a vision to provide a platform for inquiry into fundamental risk-related concepts and theories, and to disseminate new knowledge about methods and approaches for identifying, analyzing, evaluating, managing, and communicating risk. The journal has also contributed significantly to a scientific understanding of specific risks related to human health and safety, engineering, ecological, and social systems. Published on behalf of the Society for Risk Analysis, the journal has become a leading platform over its 40-year history. Complementing recent celebratory overviews and perspectives on the evolution, achievements, and future challenges for Risk Analysis, this article presents a scientometric overview of the journal between 1981 and 2020. The study presents high-level insights in the journal publication trends and structure and trends in the leading countries/regions, institutions, and authors, in relation to their respective collaboration networks. Furthermore, the structure and evolution of research focus issues is analyzed, and highly cited publications are identified. The findings are primarily intended to provide high-level insights, which may be useful for early career academics and risk practitioners to understand the structure and development of the research domain, and its main contributors and topics, and for experienced researchers to reflect on the achievements and future developments.

    Insights in Neuropsychiatry: Suicide and Self-Mutilation in the Mena Region- a Bibliometric Quantitative and Co-occurrence Medline-Based Analysis.
    Elyas Wakim, Said El Hage, Steven Safi, Antonio El Kareh, Jad El Masri, Pascale Salameh.
      Background  Little is known about self-mutilation and suicide-related research in the Arab world. Aim We aim to quantify research activity related to suicide and self-mutilation, according to socio-economic factors, and assess inter-regional collaborations and trends of topics in the Arab world in the last 16 years. Methods A search was conducted through the PubMed database to find articles related to suicide and self-mutilation, according to author affiliation in the 22 Arab countries between 2004 and 2019 (inclusive), and standardized according to mean population, suicide, and self-mutilation disability associated life years (DALY), and gross domestic product (GDP). VOS Viewer was used for keyword and organization co-occurrence analysis. Results Only 0.61% of articles related to suicide and self-mutilation published between 2004 and 2019 were of Arab origin, compared to 1.76% in South America and 7.94% in Far East Asia. Suicide and self-mutilation articles make up 0.09% of the total publications in the Arab region. Egypt, Saudi Arabia, and Lebanon had the highest number of published articles related to suicide and self-mutilation. When comparing publications per million persons, Lebanon and Kuwait ranked first with 5.15 and 3.40 publications per million persons. Lebanon showed the highest number of publications per USD billion GDP, with 0.75 publications. The highest number of publications per 1% self-injury-related DALY was recorded in Saudi Arabia, with 46.97 publications. In recent years, VOS Viewer revealed poor inter-regional collaborations and a modest but increasing trend towards depression, poisoning, and cross-sectional studies. Conclusion Despite increasing publications, the region still lags in terms of suicide and self-mutilation research activity. A pan-Arab strategy should be implemented to refine suicide-related research and increase mental health awareness.

    Knowledge atlas of post-traumatic epilepsy research: Based on citespace visualization analysis.
    Jingjing Zhan, Yixun Ma, Dong Zhao, Zheng Li, Huachao Tan, Xu Wang, Hongxia Liu, Tiantong Yang.
      The mechanism of posttraumatic epilepsy (PTE) is complicated and the treatment and prognostic effects are not satisfactory. In this study, CiteSpace and VOSviewer are used to analyze the literature related to PTE (January 2000-June 2020). The aspects of the cooperative network (author, institution, and country), keywords co-occurrence, document co-citation clustering, and journal dual-map overlay were analyzed, and the atlas was constructed. The United States, Finland, and other research institutions have frequently published PTE-related articles, thus having richer research results. The relevant research was mostly published in journals, such as Journal of Neurotrauma, Journal of Neuroscience, Brain Research, Neurobiology of Disease. Quantitative diffusion MRI plays a critical role in PTE research. The study on the susceptibility to seizures and the underlying mechanism of PTE received different degrees of attention. The present study provided an in-depth understanding of the research foundation, relevant research results, the current research frontiers, and the main research focus in the PTE field. Herein, we briefly discussed relevant key articles and also provided ideas for future research directions.

    Knowledge Hiding: Current Research Status and Future Research Directions.
    Peixu He, Cuiling Jiang, Zhixing Xu, Chuangang Shen.
      This article provides a review of scientific articles addressing the topic of knowledge hiding in organizations. Based on a descriptive analysis, bibliometric analysis, and content analysis of a sample of 81 articles published in the academic journals in the Web of Science from 2012 to 2020, we identify the main areas and current dynamics of knowledge hiding research. Our results show that the central research themes of knowledge hiding include five clusters: concept and dimensions, antecedents, consequences, theories, and influence mechanisms. Based on our findings, we suggest future research should further develop the concept and dimensions of knowledge hiding; probe deeper into the consequences of knowledge hiding; explore multilateral, cross-level, and collective knowledge hiding; employ innovative theoretical perspectives and research methods to study knowledge hiding; and address how cultural and other contextual factors may shape the knowledge hiding behavior.

    Women's Authorship of Reviews in Ophthalmic Journals Over Time.
    Demi Gertig, Miriam C Keane, Janet M Matthews, Keryn A Williams, Justine R Smith.
      PURPOSE: To investigate prevalence and trends in women's authorship of articles in ophthalmic review journals over 2 decades.DESIGN: Literature survey.
    METHODS: Total number of authors, and number and gender of first and senior (last-named) authors, were identified in all full reviews published in Prog Retin Eye Res, Surv Ophthalmol, and Curr Opin Ophthalmol for the calendar years 1999, 2009, and 2019. The gender of authors was assigned manually by multiple methods. The subspecialty area of each review was captured by keyword and text search. Country of origin was determined from attributions of first and senior authors.
    RESULTS: The gender of 841 first and senior authors was assigned unequivocally for 471 articles (96%). The frequency of women's authorship rose significantly over time (1999, 2009, 2019) for both first authors (19%, 32%, 44%; P < 0.001) and senior authors (16%, 19%, 29%; P = 0.018). The number of single-author reviews decreased significantly over time (P < 0.001), as did the proportion of reviews with neither a first nor a senior woman author (P < 0.001). Women's first authorship increased over time for reviews on glaucoma (P < 0.001), while women's senior authorship increased for anterior segment/cataract (P = 0.036). The proportion of reviews with a woman first or senior author did not differ by country of origin (P = 0.887 and P = 0.520, respectively).
    CONCLUSIONS: Women's authorship of articles in ophthalmic review journals increased significantly over the 20-year period, but a gender disparity remained: in 2019, more than 55% of first authors, and more than 70% of senior authors, were men.

    Evaluating Strength of Evidence of Pediatric Otolaryngology Research Literature: A 20-Year Review.
    Jennifer A Silver, Jeffrey C Yeung, Deema Almutawa, Rachel Szwimer, Lily H P Nguyen.
      OBJECTIVES/HYPOTHESIS: Quantity and quality of Otolaryngology-Head and Neck Surgery (OTL-HNS) research are increasing, yet patterns within Pediatric OTL-HNS publications are unknown. This study examines trends in the level of evidence of pediatric OTL-HNS articles over a 20-year period to quantify the growth and characterize contributing factors.STUDY DESIGN: Review article.
    METHODS: A retrospective review was conducted on 12 peer-reviewed OTL-HNS journals at three time-points: 1996, 2006, and 2016. Pediatric-specific OTL-HNS journals were selected; all were among the top 10 highest impact factor journals, with one pediatric-specific and one Canadian journal. Publication details, author characteristics, and study focus were collected. Papers were classified based on the Oxford Centre for Evidence-Based Medicine Levels of Evidence by two independent reviewers.
    RESULTS: Of the 1,733 articles reviewed, 727 met inclusion criteria. A greater absolute number of pediatric OTL-HNS articles were published over the years studied: from 95 in 1996 to 359 in 2016 (P < .001). As well, the absolute number of high-quality studies has increased over the study period, from 28 articles in 1996 to 100 articles in 2016. However, the relative percentage of high-quality papers remained stable between 27.9% and 32.2% with an average of 29.7% (P = .89). Higher impact factor journals did not tend to publish higher-quality pediatric OTL-HNS articles (P = .48).
    CONCLUSIONS: Over the past 20 years, there is no appreciable improvement in the proportion of high-quality publications in pediatric OTL-HNS; however, there is an overall greater number of high-quality papers within OTL-HNS literature. These findings likely relate to challenges of research within pediatric surgical specialties.

    Scoping and bibliometric analysis of promoters of therapeutic inertia in hypertension.
    Ramzi Shawahna.
      OBJECTIVES: Therapeutic/clinical inertia is thought to be responsible for up to 80% of cardiovascular events. This study was conducted as a comprehensive scoping and bibliometric analysis of peer-reviewed scholarly documents reporting on factors associated with therapeutic/clinical inertia in caring for patients with hypertension. Additionally, this study identified the factors associated with therapeutic/clinical inertia in hypertension.STUDY DESIGN: This study was a scoping and bibliometric analysis.
    METHODS: The databases MEDLINE/PubMed, Embase, CINAHL/EBSCO, Cochrane, and Scopus were searched from inception to September 23, 2020, using relevant keywords. Documents reporting on factors associated with therapeutic/clinical inertia in caring for patients with hypertension were selected based on inclusion criteria. Bibliometric indicators and VOSviewer were used to analyze and map citation and keyword networks.
    RESULTS: Data were collected from 71 documents. Of those, 43 (60.6%) were original articles, 54 (76.1%) were published after 2010, and 41 (57.7%) originated from the United States. Mapping cooccurrence of terms identified 112 hot topics that were grouped into 4 clusters. A total of 41 factors associated with therapeutic/clinical inertia were identified from the documents selected. Of those, 23 (56.1%) were related to the physician, 12 (29.3%) were related to the patient, and 6 (14.6%) were related to the health care system.
    CONCLUSIONS: This scoping and bibliometric study provides insights into the width and depth of scholarly peer-reviewed documents on factors associated with therapeutic/clinical inertia in caring for patients with hypertension. Findings of this study could be helpful in shaping future directions of research into therapeutic/clinical inertia in hypertension.

    Visualization and analysis of mapping knowledge domains for the global transition towards clean cooking: a bibliometric review of research output from 1990 to 2020.
    Sandylove Afrane, Jeffrey Dankwa Ampah, Emmanuel Aboagye Mensah.
      Current statistics report that 2.6 billion households across the globe rely on polluting and inefficient cooking fuels and technologies, posing death-threatening health risks to people mainly from developing countries/regions. Several studies on clean cooking have been conducted with the emergence of international organizations such as the Clean Cooking Alliance to raise awareness. In the current study, a bibliometric tool, CiteSpace, was employed to analyze the 877 documents retrieved from the SCI-EXPANDED, SSCI, and A&HCI databases on clean cooking research from 1990 to 2020. The results reveal that interest in clean cooking research took a sharp rise in the last decade, especially after 2016. The research field has become increasingly interdisciplinary but has mostly centered on environment, energy, and health. The most productive countries/regions in this field are the USA, India, England, and China. The keyword and citation analyses indicate that research in this field mostly focuses on adverse impacts of household air pollution from unclean cooking fuels and technologies on the environment and public health particularly, in developing countries/regions. Also, the drivers and barriers to the large-scale adoption of clean cooking fuels and technologies have become a topic of interest in recent years. The three most studied clean cooking fuels among various regions are LPG, biogas, and electricity. This study synthesizes global research on clean cooking and may be beneficial to other researchers in understanding current trends in this field and serve as a guide for concentrating on the most important topics.

    Scientific Literacy in Communicating Science and Socio-Scientific Issues: Prospects and Challenges.
    Yanyan Li, Mengmeng Guo.
      A holistic view of scientific literacy-related literature was generated based on bibliometric analysis. The purpose was to provide insight into and knowledge on evolving knowledge fronts and to highlight the turning points in the existing literature between 1980 and 2019. Scientific literacy in society can potentially help to answer unsolved riddles of socio-scientific issues (SSI) to enable people to become smart and responsible global citizens. Specifically, two decades before and after the year 2000 was taken into account as it comprised the most noticeable revolutionary developments in terms of economics, technology, culture, and society. Interestingly, the attention paid to scientific literacy significantly increased after the financial crisis of 2008. International Journal of Science Education and the Journal of Research in Science Teaching were observed to be the top-cited and top publishing journals, respectively. Similarly, Jonathan Osborne, Rosalind Driver, and Norman G. Lederman were recorded as the most cited and most published authors, respectively, during the study period. Alarmingly, most of the literature evolved in and was dominated by the Western region, indicating the need to understand the regional-cultural complexities of the East and the rest of the world. The recent evolving clusters, with titles of literacy (as a concept), learning progression, and informal reasoning, were observed to be currently active knowledge areas in the evolution of the intellectual structure of scientific literacy-related literature. However, no recent trend or emerging research direction was noticed in the last decade, even though new and digital media (including immersive media) have revolutionized the communication channels and public understanding of science and socio-scientific issues.

    Head and neck research in plastic surgery-Ahead of the rest? An analysis of abstracts presented at British association of plastic reconstructive and aesthetic surgeons meetings.
    Alexander S North, Thomas P Kidd, Calum M Ferris, Alexander S Dearden, Maniram Ragbir.
      INTRODUCTION & AIMS: Historically, the head and neck (H&N) discipline has been integral to the service a plastic surgeon provides. Recently, it has been postulated that its popularity is declining. The output of scientific meetings may indicate the popularity of each sub-speciality interest, also allowing comparison with other H&N conferences.AIM: To analyse the proportion of H&N themed, podium and poster presentations from British Association of Plastic Reconstructive and Aesthetic Surgeons' (BAPRAS) scientific meetings and the resulting contribution to published literature.
    MATERIAL AND METHODS: H&N-themed abstracts were identified from finalised programmes of the biannual BAPRAS meetings between 2008 and 2015. PubMed and Google Scholar databases were searched using keywords and author names from each abstract to identify subsequent publication in a peer-reviewed journal.
    RESULTS: Overall, 19.3% (350/1815) of BAPRAS abstracts were H&N themed. The publication rate of H&N abstracts was 40.3% (141/350), comprising 43.0% (114/265) of podium and 31.8% (27/85) of poster presentations. H&N reconstruction and cleft and craniofacial were the most frequent topics, with facial palsy having the lowest conversion rate at 15.4%. The mean time to publication was 17.8 months. Research was published in 39 journals, with a mean impact factor of 2.151 (range = 0.772-11.541). The most popular journal was Journal of Plastic, Reconstructive & Aesthetic Surgery (JPRAS; 31.7%; 45/141). Published abstracts originated from 17 different countries. The senior author was a plastic surgeon in 77.3% of abstracts.
    CONCLUSIONS: From the multiple potential sub-specialties, H&N-themed abstracts consistently contributed 20% of all research presented at BAPRAS. The 40.3% publication rate exceeds the international average of scientific meetings. H&N remains a prominent field in the armamentarium of a plastic surgeon.

    Research on the Emotions Based on Brain-Computer Technology: A Bibliometric Analysis and Research Agenda.
    Wei Yan, Xiaoju Liu, Biaoan Shan, Xiangxian Zhang, Yi Pu.
      This study conducts a scientific analysis of 249 literature on the application of brain-computer technology in emotion research. We find that existing researches mainly focus on engineering, computer science, neurosciences neurology and psychology. PR China, United States, and Germany have the largest number of publications. Authors can be divided into four groups: real-time functional magnetic resonance imaging (rtfMRI) research group, brain-computer interface (BCI) impact factors analysis group, brain-computer music interfacing (BCMI) group, and user status research group. Clustering results can be divided into five categories, including external stimulus and event-related potential (ERP), electroencephalography (EEG), and information collection, support vector machine (SVM) and information processing, deep learning and emotion recognition, neurofeedback, and self-regulation. Based on prior researches, this study points out that individual differences, privacy risk, the extended study of BCI application scenarios and others deserve further research.

    Sex Disparity Among Canadian Cardiologists in Academic Medicine: Differences in Scholarly Productivity and Academic Rank.
    Jacqueline Rano, Sabeena Jalal, Tara Sedlak, Javed Butler, Muhammad S Khan, Warren J Manning, Faisal Khosa.
      Background Women remain relatively underrepresented in all subspecialties of academic medicine. While sex disparity is prevalent in a number of specialties, the association between academic productivity and sex in academic cardiology has not been assessed in the Canadian context. Methods Academic faculty of accredited Canadian Resident Matching Service (CaRMS) programs were included from cardiology division websites across 17 universities. Cardiology faculty members' names, academic ranks, leadership positions, and sex were obtained from each institutions' website. The Elsevier database Scopus© was used to extract the Hirsch index (H-index), years of active research, and number of publications of each faculty member. The H-index was used as a metric of academic output and research productivity. Univariate regression was run with the H-Index as the outcome of interest, and multiple linear regression analysis was used to determine factors associated with higher H-index. Results Sex was identified for 1,040 members, of whom 836 (80%) were male. Male members had higher numbers of publications (p <0.001). There was a trend for males in a leadership position to have a higher H-index (p = 0.07). Median H-index was lower for women (p = 0.02). Males across assistant and associate professor ranks had a higher H-index. Women achieving professor rank demonstrated greater productivity with a higher median H-index (p = 0.002). Conclusions There is a prevalent sex gap in academic cardiology with regard to scholarly productivity and academic achievement. Factors that may help narrow the sex gap need to be identified and corrective measures implemented to enhance sex equity.

    Subspecialty Selection Impacts Research Productivity and Faculty Rank of Academic Orthopaedic Surgeons.
    Sean Haimowitz, Jacob Veliky, Lynn Ann Forrester, Joseph Ippolito, Kathleen Beebe, Alice Chu.
      BACKGROUND: Faculty promotion and research productivity are important for the overall career trajectory of academic orthopaedic surgeons. The purpose of this study was to investigate the role that subspecialty and demographic factors play in research productivity and academic advancement among orthopaedic surgeons.METHODS: We conducted a retrospective cross-sectional analysis of academic rank among orthopaedic surgeons in 2018. We identified academic orthopaedic programs in the United States from the Fellowship and Residency Electronic Interactive Database (FREIDA) and collected publicly available data for surgeons, including fellowship training, gender, faculty rank, geographic region, and years since residency, from institutional websites. Research productivity was defined with the Hirsch index (h-index) from Scopus, and the m-index was calculated from the surgeon's h-index and the date of the first publication. Multivariate regression analyses were performed to determine the variables that are associated with associate professorship, full professorship, and the h-index.
    RESULTS: In this study, we identified and included 2,879 academic orthopaedic surgeons. Completion of a fellowship in foot and ankle (odds ratio [95% confidence interval]: 2.45 [1.17 to 5.15]), sports medicine (2.15 [1.12 to 4.15]), trauma (2.83 [1.42 to 5.66]), hand and upper extremity (2.20 [1.13 to 4.28]), musculoskeletal oncology (3.28 [1.49 to 7.21]), or upper-extremity reconstruction (3.20 [1.31 to 7.81]) was associated with associate professorship. Completion of a trauma fellowship was associated with full professorship (2.93 [1.27 to 6.77]). Completion of a fellowship in adult reconstruction (difference in least-squares means [95% confidence interval]: 5.01 [1.22 to 8.81]), sports medicine (4.52 [1.00 to 8.04]), spine (5.40 [1.63 to 9.18]), or upper-extremity reconstruction (10.64 [6.15 to 15.12]) or the completion of multiple fellowships (5.12 [1.27 to 8.94]) were independently associated with a higher h-index. Women had significantly lower h-indices than men at the assistant (median [interquartile range]: 3 [1 to 6] versus 4 [2 to 8]) and full professor (17 [12 to 26] versus 22 [13 to 34]) levels. There were no differences in the m-index between men and women at any academic rank.
    CONCLUSIONS: Orthopaedic subspecialty selection is independently associated with research productivity and academic rank. The differences in research productivity may be important to consider when evaluating orthopaedic surgeons for promotion. While female surgeons had lower h-indices than their male counterparts, this difference was not seen when using the m-index.

    Evidence-Based Blepharoplasty: An Analysis of Highly Cited Research Papers.
    Walton N Charles, Hong Kai Lim, Roselin C Charles, Mhafrin Basta, Ankur Khajuria.
      PURPOSE: The purpose of the study was to appraise the methodological quality of the highest impact blepharoplasty research and to describe prevalent research themes.METHODS: The 100 most highly cited research papers relevant to blepharoplasty were obtained from Web of Science, with no journal or date limitations applied. Data extraction included the study design, main research topic and specialty, outcome measures, and citation count. Each paper's level of evidence was independently evaluated by 2 authors according to the Oxford Centre for Evidence-Based Medicine system.
    RESULTS: Overall, the 100 most cited blepharoplasty research papers were cited by 4,194 papers. The mean number of citations for each paper was 73 (range: 42-239). Most of the papers presented level 4 (n = 51) or level 5 (n = 35) evidence, which is consistent with the predominance of case series (n = 47) and expert opinions (n = 18) amongst study designs. No papers achieved level 1 (highest) evidence. Six papers presented level 2 evidence and 8 papers presented level 3. Significant research foci included innovative surgical techniques (n = 65) and anatomical considerations (n = 10), with reconstructive and cosmetic implications. Senior authors were mainly affiliated with centers of plastic (n = 53) or ophthalmic/oculoplastic (n = 34) surgery. Only 3 papers used validated subjective or objective cosmetic outcome measures.
    CONCLUSIONS: Despite a significant impact on current practice, the level of evidence of the highly cited blepharoplasty research was predominantly low. Robust research methodology, through well-designed studies and standardized outcome measures, is necessary to facilitate evidence synthesis and guide clinical practice.

    Is coronavirus-related research becoming more interdisciplinary? A perspective of co-occurrence analysis and diversity measure of scientific articles.
    Yi Zhao, Lifan Liu, Chengzhi Zhang.
      The outbreak of coronavirus disease 2019 (COVID-19) has had a significant repercussion on the health, economy, politics and environment, making coronavirus-related issues more complicated and difficult to adequately address by relying on a single field. Interdisciplinary research can provide an effective solution to complex issues in the related field of coronavirus. However, whether coronavirus-related research becomes more interdisciplinary still needs corroboration. In this study, we investigate interdisciplinary status of the coronavirus-related fields via the COVID-19 Open Research Dataset (CORD-19). To this end, we calculate bibliometric indicators of interdisciplinarity and apply a co-occurrence analysis method. The results show that co-occurrence relationships between cited disciplines have evolved dynamically over time. The two types of co-occurrence relationships, Immunology and Microbiology & Medicine and Chemical Engineering & Chemistry, last for a long time in this field during 1990-2020. Moreover, the number of disciplines cited by coronavirus-related research increases, whereas the distribution of disciplines is uneven, and this field tends to focus on several dominant disciplines such as Medicine, Immunology and Microbiology, Biochemistry, Genetics and Molecular Biology. We also measure the disciplinary diversity of COVID-19 related papers published from January to December 2020; the disciplinary variety shows an upward trend, while the degree of disciplinary balance shows a downward trend. Meanwhile, the comprehensive index 2Ds demonstrates that the degree of interdisciplinarity in coronavirus field decreases between 1990 and 2019, but it increases in 2020. The results help to map the interdisciplinarity of coronavirus-related research, gaining insight into the degree and history of interdisciplinary cooperation.

    Microalgae cultivation in wastewater from agricultural industries to benefit next generation of bioremediation: a bibliometric analysis.
    Jessica Muniz Melo, Marina Ronchesel Ribeiro, Tiago Santos Telles, Higo Forlan Amaral, Diva Souza Andrade.
      The aim of this study was to provide a bibliometric analysis and mapping of existing scientific papers, focusing on microalgae cultivation coupled with biomass production and bioremediation of wastewater from agricultural industries, including cassava, dairy, and coffee. Using the Web of Science (WoS) database for the period 1996-2021, a search was performed using a keyword strategy, aiming at segregating the papers in groups. For the first search step, the keywords "wastewater treatment", AND "microalgae", AND "cassava" OR "dairy" OR "coffee" were used, resulting in 59 papers. For the second step, the keywords "wastewater treatment" AND "biomass productivity" AND "microalgae" AND "economic viability" OR "environmental impacts" were used, which resulted in 34 articles. In these papers, keywords such as "carbon dioxide biofixation" and "removal of nutrients by the production of biomass by microalgae" followed by "environmental and economic impacts" were highlighted. Some of these papers presented an analysis of the economic feasibility of the process, which reveal the state-of-the-art setup required to make the cultivation of microalgae economically viable. Researches focusing on the efficiency of microalgae biomass harvesting are needed to improve the integration of microalgae production in industrial eco-parks using wastewater to achieve the global goal of bioremediation and clean alternatives for renewable energy generation.

    The State of Diversity in Academic Plastic Surgery Faculty across North America.
    Sahil Chawla, Amey Chawla, Mehwish Hussain, Ahmer A Karimuddin, Faisal Khosa.
      Background: Gender and racial disparity is prevalent in all surgical subspecialties with women and racial groups historically underrepresented in academic plastic surgery. This study evaluated gender and racial profiles of academic plastic surgery faculty in North America and correlated both with research productivity and its effect on academic ranks of faculty in plastic surgery.Methods: In this cross-sectional study, we compiled a list of accredited medical schools that offer plastic surgery training for residency. Data were collected on demographics, academic rank, and research output using the Doximity, LinkedIn, and Scopus databases. Data analyses were performed with a Mann-Whitney U test and a Kruskal-Wallis test.
    Results: Women who were black, indigenous, and/or other color occupied only 6.25% of plastic surgery faculty leadership positions in North America. There are more women and underrepresented minorities in leadership positions in Canada, when compared with the USA, relative to each country's demographic. In both countries, women and underrepresented minority plastic surgeons had fewer publications, citations, and years of active research. Interestingly, having women in leadership positions was associated with a higher number of women faculty members.
    Conclusions: Gender and racial disparity exist in academic plastic surgery in North America. Several changes are required in order for women and underrepresented minorities in medicine to have an equal chance at career advancement. Better representation and diverse leadership have the potential to bring about equity, diversity, and inclusion in academic plastic surgery.

    Application of a feature extraction and normalization method to improve research evaluation across clinical disciplines.
    Rui Liu, Qian Liu, Jianwei Shi, Wenya Yu, Xin Gong, Ning Chen, Yan Yang, Jiaoling Huang, Zhaoxin Wang.
      Background: To deal with the large disparity across disciplines using impact factor, which is widely used in hospitals and has recently come under attack for distorting good scientific practices, we propose a set of systematic methods to improve the equality of research evaluations of various clinical disciplines.Methods: We used bibliometric information on 18 clinical disciplines from 2016 to 2018. We first sought to clarify disciplinary characteristics with the aim of identifying the characteristic fields for each clinical discipline, and we constructed a keyword database. To minimize the disparity across various clinical disciplines, we used normalized evaluation, referring to the calculation of the normalized coefficient of a specific discipline, to enable a relatively clear evaluation across different disciplines.
    Results: Feature extraction was performed, and over 700,000 journals were retrieved each year. Using this information, the journal correlation coefficient was calculated. From 2016 to 2018, oncology had the largest normalized coefficient (0.133, 0.136, 0.146 respectively), which reflects the highest correlation between the characteristic journals of the discipline. The findings showed a clear distinction in journal coverage and journal correlations for different disciplines.
    Conclusions: The new evaluation indicator and normalized process measure different features of disciplines, providing a basis for the further balancing of evaluations, and considering differences across disciplines.

    Sleeping Beauties of Coronavirus Research.
    Mohsen Fazeli-Varzaneh, Ali Ghorbi, Marcel Ausloos, Emanuel Sallinger, Sahar Vahdati.
      A "Sleeping Beauty" (SB) in science is a metaphor for a scholarly publication that remains relatively unnoticed by the related communities for a long time; - the publication is "sleeping". However, suddenly due to the appearance of some phenomenon, such a "forgotten" publication may become a center of scientific attention; - the SB is "awakened". Currently, there are specific scientific areas for which sleeping beauties (SBs) are awakened. For example, as the world is experiencing the COVID-19 global pandemic (triggered by SARS-CoV-2), publications on coronaviruses appear to be awakened. Thus, one can raise questions of scientific interest: are these publications coronavirus related SBs? Moreover, while much literature exists on other coronaviruses, there seems to be no comprehensive investigation on COVID-19, - in particular in the context of SBs. Nowadays, such SB papers can be even used for sustaining literature reviews and/or scientific claims about COVID-19. In our study, in order to pinpoint pertinent SBs, we use the "beauty score" (B-score) measure. The Activity Index (AI) and the Relative Specialization Index (RSI) are also calculated to compare countries where such SBs appear. Results show that most of these SBs were published previously to the present epidemic time (triggered by SARS-CoV or SARS-CoV-1), and are awakened in 2020. Besides outlining the most important SBs, we show from what countries and institutions they originate, and the most prolific author(s) of such SBs. The citation trend of SBs that have the highest B-score is also discussed.

    Gender Equity of Promoting Practices in Academic Neurosurgery in the United States.
    Kathryn N Kearns, Emily P Rabinovich, Leah Shabo, Mark E Shaffrey, John A Jane, Min S Park.
      BACKGROUND: Women have historically been underrepresented in academic medicine, particularly in surgical subspecialties. This study investigates potential associations between gender and promoting practices in academic neurosurgery.METHODS: Faculty data including time from residency, professorship, specialty, and h-index were obtained from websites of the institutions listed in the American Association of Neurological Surgeons (AANS) Neurosurgical Residency Training Program Directory. Demographics, training, and appointments were compared between male and female neurosurgeons. Predictors of professorship, chair, directorship, and division leadership were identified using multivariable models.
    RESULTS: 1629 faculty members were examined. Women were more likely to be assistant professors(p<0.0001), while men were more likely to be full professors(p<0.0001), hold chair positions(p=0.007), lead subspecialty divisions(p=0.008), and have a higher Scopus h-index(p<0.0001). In a multivariable analysis, years from training(p<0.001), fellowship(p=0.009), h-index(p<0.001), and chair/program director/division leadership position(p<0.001) were significant positive predictors of full professorship. Holding additional advanced degrees(p=0.010), leading a subspecialty division(p=0.005), and having a higher h-index(p=0.002) positively predicted chair position. However, when accounting for all other factors, gender was not a significant predictor of full professorship, division leadership, chair, or program directorship.
    CONCLUSIONS: While significantly more men hold leadership positions in United States academic institutions, after controlling for contributing variables there did not appear to be an association between gender and full professorship, division leadership, chair, or program directorship in academic neurosurgery. While our field still has significant work to do to achieve gender equity, these results may serve as encouragement to women who are looking to advance their careers in academic neurosurgery.

    Therapeutic Effects of Melatonin on Ocular Diseases: Knowledge Map and Perspective.
    Haozhe Yu, Qicong Wang, Wenyu Wu, Weizhen Zeng, Yun Feng.
      Melatonin plays a critical role in the pathophysiological process including circadian rhythm, apoptosis, and oxidative stress. It can be synthesized in ocular tissues, and its receptors are also found in the eye, triggering more investigations concentrated on the role of melatonin in the eye. In the past decades, the protective and therapeutic potentials of melatonin for ocular diseases have been widely revealed in animal models. Herein, we construct a knowledge map of melatonin in treating ocular diseases through bibliometric analysis and review its current understanding and clinical evidence. The overall field could be divided into twelve topics through keywords co-occurrence analysis, in which the glaucoma, myopia, and retinal diseases were of greatest research interests according to the keywords burst detection. The existing clinical trials of melatonin in ocular diseases mainly focused on the glaucoma, and more research should be promoted, especially for various diseases and drug administration. We also discuss its bioavailability and further research topics including developing melatonin sensors for personalized medication, acting as stem cell therapy assistant drug, and consuming food-derived melatonin for facilitating its clinical transformation.

    The Research Trend of Big Data in Education and the Impact of Teacher Psychology on Educational Development During COVID-19: A Systematic Review and Future Perspective.
    Jia Li, Yuhong Jiang.
      The COVID-19 outbreak, along with post-pandemic impact has prompted Internet Plus education to re-examine numerous facets of technology-oriented academic research, particularly Educational Big Data (EBD). However, the unexpected transition from face-to-face offline education to online lessons has urged teachers to introduce educational technology into teaching practice, which has had an overwhelming impact on teachers' professional and personal lives. The aim of this present work is to fathom which research foci construct EBD in a comprehensive manner and how positive psychological indicators function in the technostress suffered by less agentic teachers. To this end, CiteSpace 5.7 and VOSviewer were applied to examine a longitudinal study of the literature from Web of Science Core Collection with the objective of uncovering the explicit patterns and knowledge structures in scientific network knowledge maps. Thousand seven hundred and eight articles concerned with educational data that met the criteria were extracted and analyzed. Research spanning 15 years was conducted to reveal that the knowledge base has accumulated dramatically after many governments' initiatives since 2012 with an accelerating annual growth and decreasing geographic imbalance. The review also identified some influential authors and journals whose effects will continue to have future implications. The authors identified several topical foci such as data mining, student performance, learning environment and psychology, learning analytics, and application. More specifically, the authors identified the scientific shift from data mining application to data privacy and educational psychology, from general scan to specific investigation. Among the conclusions, the results highlighted the important integration of educational psychology and technology during critical periods of educational development.

    The lost art of short communications in academia.
    Jeremiah Joven Joaquin, Raymond R Tan.
      Short communications are an integral part of academic journal publishing since they serve as a forum for scholarly debate on recently published journal articles. Their prestige and popularity, however, have been declining in the present academic setting. In this short note, we offer several reasons for this phenomenon.

    Examining Trends in Dermatology Publications: A 10-Year Follow-up.
    Reem Qabas Al Shabeeb, Kamaria Nelson, Kelley Redbord.
      INTRODUCTION: Examining trends in adult and pediatric dermatology publications by Mimouni et al for 15 years (1993&ndash;2007) showed that there was a higher yearly increase in articles with higher level of evidence such as clinical and randomized controlled trials with a slower rise in articles with a lower level of evidence such as letters and case reports.1 We wanted to see if trends in dermatology research have differed over the following 10 years (2008&ndash;2017).METHODS: We used the methodology of Mimouni et al to find the total number and categorization of publications in adult and pediatric dermatology from 2008 to 2017. We used MEDLINE to search the terms &lsquo;skin&rsquo; AND &lsquo;disease&rsquo; OR &lsquo;dermatology&rsquo; for adults and pediatrics. A regression analysis (SAS 9.4) was used to understand the change in frequency across the years.
    RESULTS AND DISCUSSION: By analyzing publications from 2008 to 2017, speculations mentioned in Mimouni et al held true regarding the statistically significant increase in total number of publications in addition to meta-analyses and practice guidelines, which was not shown in the 1993&ndash;2007 analysis. The statistically significant increase previously mentioned in clinical trials, case reports, and pediatric randomized controlled trials was lost in the 2008-2017 data.
    CONCLUSION: Trends in pediatric and adult dermatology publications in 2008&ndash;2017 differ from those identified in 1993&ndash;2007. There is a new significant increase in higher level of evidence not reported previously such as meta-analyses and practice guidelines. This is good for dermatology, and we hope the trend continues to further the specialty. J Drugs Dermatol. 2021;20(11)1248-1251. doi:10.36849/JDD.6088.

    The relevance of transversal competences in vocational education and training: a bibliometric analysis.
    Inmaculada Calero López, Beatriz Rodríguez-López.
      Vocational Education and Training (VET) programmes have included the acquisition of transversal competences in their curricula as a tool to increase employability. The number of researches has exponentially grown in the last years, emphasizing its relevance and the multiple approaches and factors involved in the learning process. The present bibliometric study aims to provide an overview of the scientific research carried out during the last 10 years and to shed some light on several relevant topics in this field. The results indicate the need to improve students' transversal competences in order to meet the demands of the labour market, the importance of the collaboration of all the actors involved in the process (policy makers, industry and educators) and from a pedagogical point of view, the necessity of introducing new teaching approaches to implement and assess the acquisition of transversal competences. However, and despite the surge of interest in the study of transversal competences in the last decade, further empirical research is needed, especially at Vocational Education and Training level, to understand how transversal competences develop and what kind of initiatives have an impact of their acquisition.

    High variability in results and methodological quality among overlapping systematic reviews on the same topics in surgery: a meta-epidemiological study.
    Morihiro Katsura, Akira Kuriyama, Masafumi Tada, Yasushi Tsujimoto, Yan Luo, Kazumichi Yamamoto, Ryuhei So, Masaharu Aga, Kazuhide Matsushima, Shingo Fukuma, Toshi A Furukawa.
      BACKGROUND: Redundant publication of systematic reviews and meta-analyses (SRs/MAs) on the same topic presents an increasing burden for clinicians. The aim of this study was to describe variabilities in effect size and methodological quality of overlapping surgery-related SRs/MAs and to investigate factors associated with their postpublication citations.METHODS: PubMed/MEDLINE was searched to identify SRs/MAs of RCTs on thoracoabdominal surgeries published in 2015. Previous SRs/MAs on the same topics published within the preceding 5 years (2011-2015) were identified and 5-year citation counts (through to 2020) were evaluated. Discrepancies in pooled effect sizes and their methodological quality using A Measurement Tool to Assess Systematic Reviews (AMSTAR) among overlapping SRs/MAs were assessed. The SR/MA-level factors associated with 5-year citation counts were explored, using a mixed-effects regression model with a random intercept for surgical topics.
    RESULTS: A total of 57 surgery-related SRs/MAs (48 topics) published in 2015 were identified, and 146 SRs/MAs had overlapping publications on 29 topics (60.4 per cent of all topics) in the preceding 5 years. There was considerable variability in methodological quality of SRs/MAs and coverage probability for relevant RCTs, resulting in discrepant effect size estimates for the same topic. High quality (AMSTAR score 8-11) was independently associated with higher 5-year citation counts (coefficient = 32.82; 95 per cent c.i. 15.63 to 50.02; P < 0.001).
    CONCLUSION: Overlapping SRs/MAs with high variability in results and methodological quality were common in surgery. A high-quality SR/MA score was an independent predictor of more frequent citations. Researchers and journal editors should concentrate their efforts on limiting publications to higher-quality reviews.

    The top 100 Twitter influencers in cardiology.
    Onoriode Kesiena, Henry K Onyeaka, Setri Fugar, Alexis K Okoh, Annabelle Santos Volgman.
      Importance: Twitter represents a growing aspect of the social media experience and is a widely used tool for public education in the 21st century. In the last few years, there has been concern about the dissemination of false health information on social media. It is therefore important that we assess the influencers of this health information in the field of cardiology.Objective: We sought to identify the top 100 Twitter influencers within cardiology, characterize them, and examine the relationship between their social media activity and academic influence.
    Design: Twitter topic scores for the topic search "cardiology" were queried on May 01, 2020 using the Right Relevance application programming interface (API). Based on their scores, the top 100 influencers were identified. Among the cardiologists, their academic h-indices were acquired from Scopus and these scores were compared to the Twitter topic scores.
    Result: We found out that 88/100 (88%) of the top 100 social media influencers on Twitter were cardiologists. Of these, 63/88 (72%) were males and they practiced mostly in the United States with 50/87 (57%) practicing primarily in an academic hospital. There was a moderately positive correlation between the h-index and the Twitter topic score, r = +0.32 (p-value 0.002).
    Conclusion: Our study highlights that the top ranked cardiology social media influencers on Twitter are board-certified male cardiologists practicing in academic settings in the US. The most influential on Twitter have a moderate influence in academia. Further research should evaluate the relationship between other academic indices and social media influence.

      Implementing the best research principles initiates an important shift in clinical research culture, improving efficiency and the level of evidence obtained. In this article, we share our own view on the best research practice and our experience introducing it into the scientific activities of the N.N. Burdenko National Medical Research Center of Neurosurgery (Moscow, Russian Federation). While being adherent to the principles described in the article, the percentage of publications in the international scientific journals in our Center has increased from 7% to 27%, with an overall gain in the number of articles by 2 times since 2014. We believe it is important that medical informatics professionals equally to medical experts involved in clinical research are familiar with the best research principles.

    Scholarly maturation and other factors supporting publishing productivity in educational scholarship for clinical faculty.
    Eliza A Dy-Boarman, Bethany Wippermann, Kristin K Janke.
      INTRODUCTION: In order to advance curricula and faculty career progression, it would be helpful to increase publishing success and productivity in educational scholarship. The objective of this study was to describe the key factors and strategies that contribute to publishing success and productivity in the publication of educational scholarship by clinical pharmacy faculty.METHODS: Participants were identified from 2007 to 2016 PubMed and Science Direct publication records or by having received the American Association of Colleges of Pharmacy Emerging Teaching Scholars Award. Participants were required to have an active clinical practice and not have administrative positions or doctor of philosophy training. Qualitative data were gathered through dyadic and individual interviews and analyzed to identify core factors contributing to publishing success and productivity.
    RESULTS: Nine clinical pharmacy faculty participated in dyadic or individual interviews, including seven associate professors and two professors. Participants' teaching and learning publications covered two to 13 topic areas, and participants had 20 to 70 unique co-authors. Five core factors and 17 strategies were identified as supporting publishing success and productivity in educational scholarship. The five factors included inputs/assets, the team, the project, the process, and scholarly maturation.
    CONCLUSIONS: Participants' responses confirm some conceptions, while also disputing common misconceptions that may discourage clinical faculty from pursuing educational scholarship. Fundamental research skill development is required in educational scholarship as in other scholarly areas. In addition, the roles of team building, receiving and providing mentorship, and the development of small significant networks merit further investigation as assets to productivity.

    Author Diversity on Clinical Practice Guideline Committees.
    Monica Verduzco-Gutierrez, Nicole B Katz, Talya K Fleming, Emily M Silver, Tracey L Hunter, Nuha El Sayed, Miguel X Escalon, Gianni R Lorello, Julie K Silver.
      ABSTRACT: Reports have demonstrated that women overall and women physicians in particular, are underrepresented as authors of clinical practice guidelines (CPGs). This analysis used publicly available information to explore the diversity of rehabilitation-related CPG authors by gender, race, and ethnicity. Primary analysis identified authors' gender, race, ethnicity, and visible minority status. Two sets were analyzed: (1) CPGs by Department of Veterans Affairs categorized as "Rehabilitation" or "Pain" (n = 7; VA CPGs); and, (2) a set (n = 10) published in the United States (US) from 2019-2021 and were selected due to low numbers of inclusion at less than 20% women authors. Key findings are among physician authors both VA and US CPGs underrepresented women (15 [24.2%] and 27 [16.7%], respectively) and those coded as a racial or ethnic minority were particularly underrepresented. Notably, women authors overall were equally represented (92 [50.0%]) in the VA CPGs. The US CPGs had women authors were underrepresented (36 [19.0%]). Secondary analysis of the entire set of VA CPGs (n = 21) found gaps in diversity-related content. CPGs have far-reaching impact health and economic impact and addressing disparities in the diversity of author teams and/or gaps in diversity-related content is of paramount importance.

    Downstream funding success of early career researchers for resubmitted versus new applications: A matched cohort.
    Jamie Mihoko Doyle, Michael T Baiocchi, Michaela Kiernan.
      BACKGROUND: Early career researchers face a hypercompetitive funding environment. To help identify effective intervention strategies for early career researchers, we examined whether first-time NIH R01 applicants who resubmitted their original, unfunded R01 application were more successful at obtaining any R01 funding within 3 and 5 years than original, unfunded applicants who submitted new NIH applications, and we examined whether underrepresented minority (URM) applicants differentially benefited from resubmission. Our observational study is consistent with an NIH working group's recommendations to develop interventions to encourage resubmission.METHODS AND FINDINGS: First-time applicants with US medical school academic faculty appointments who submitted an unfunded R01 application between 2000-2014 yielded 4,789 discussed and 7,019 not discussed applications. We then created comparable groups of first-time R01 applicants (resubmitted original R01 application or submitted new NIH applications) using optimal full matching that included applicant and application characteristics. Primary and subgroup analyses used generalized mixed models with obtaining any NIH R01 funding within 3 and 5 years as the two outcomes. A gamma sensitivity analysis was performed. URM applicants represented 11% and 12% of discussed and not discussed applications, respectively. First-time R01 applicants resubmitting their original, unfunded R01 application were more successful obtaining R01 funding within 3 and 5 years than applicants submitting new applications-for both discussed and not discussed applications: discussed within 3 years (OR 4.17 [95 CI 3.53, 4.93]) and 5 years (3.33 [2.82-3.92]); and not discussed within 3 years (2.81 [2.52, 3.13]) and 5 years (2.47 [2.22-2.74]). URM applicants additionally benefited within 5 years for not discussed applications.
    CONCLUSIONS: Encouraging early career researchers applying as faculty at a school of medicine to resubmit R01 applications is a promising potential modifiable factor and intervention strategy. First-time R01 applicants who resubmitted their original, unfunded R01 application had log-odds of obtaining downstream R01 funding within 3 and 5 years 2-4 times higher than applicants who did not resubmit their original application and submitted new NIH applications instead. Findings held for both discussed and not discussed applications.
