    Christopher M Mikhail, John T Schwartz, Joseph Barbera, Stephen R Selverian, Darwin Chen.
       Background: Citation analysis is a commonly used method for appraising the impact of academic publications within a particular field of study. A gap exists in the citation analysis literature with regard to the topic of direct anterior approach (DAA) hip arthroplasty. The purpose of this study is to identify the 50 most frequently cited publications related to this topic.
    Methods: The Clarivate Analytics Web of Knowledge database was utilized to search for publications relating to DAA hip arthroplasty. The top 50 most cited articles that met inclusion criteria were recorded and reviewed for various metrics.
    Results: The top 50 publications were cited a total of 3521 times, with an average of 86.3 total citations per year between 1980 and 2019. 47 of the 50 articles identified had been published since the year 2000. Cohort designs were the most common study type.
    Conclusions: This analysis provides insight into factors that characterize highly cited articles on the specific topic of DAA hip arthroplasty. These factors include higher levels of evidence, recent publication, and origin in the United States. Citations of DAA hip arthroplasty papers appear to be on the rise. The curation and analysis of this set of 50 articles will provide orthopaedic surgery clinicians, researchers, and residency program directors a guide for quickly isolating influential articles on the topic of DAA hip arthroplasty. This may serve as a quick reference for clinical decision-making, foundation for further research, and curriculum on DAA hip arthroplasty.

    Global research trends in complex oral sensitivity disorder: a systematic bibliometric analysis of the framework.
    Giulio Fortuna, Massimo Aria, Carmela Iorio, Michele D Mignogna, Gary D Klasser.
       OBJECTIVES: A systematic bibliometric analysis was performed to investigate trends in Complex Oral Sensitivity Disorder (COSD) research worldwide and compare the contributions of different countries/institutions, scientific journals, authors, keywords, and citations.
    METHODS: Web of Science database from 1985 to 2018 was systematically searched to identify all relevant articles using the MeSH terms "complex oral sensitivity disorder" and all synonyms used in the literature. We included original articles, review articles, letters to the editor, and book chapters in the English language and in 27 different ISI categories of medical sciences. Several bibliometric indicators were used.
    RESULTS: We identified 10,633 articles, of which only 3,349 were eligible with only 443 being included for quantitative analyses. The annual percentage growth rate for article publication was 9.16 fractionalized articles with the most productive countries (reported only in 428 out of 443 articles) being Italy (n=66, 15.42%) followed by USA (n=61, 14.25%) and with Italy achieving the greatest number of citations (n=1415). Similarly, the most productive institution for article publication was the University of Turku, Finland with 39 (8.8%) published articles. Among the top twenty departments, 15 were affiliated with dental institutions. The most productive source was "Journal of Oral Pathology and Medicine" with 38 (8.58%) articles, whereas the most productive author was "Lopez-Jornet P" with 19 articles (6.52 fractionalized articles).
    CONCLUSIONS: There is an increasing trend for publications on COSD. Collaboration among different countries must improve in order to implement research on this disorder, which seems to be mainly a condition for the dental discipline.

    Bibliometric analysis of publications on research into cotton leaf curl disease.
    Ayyaz Khan, Darya Khan, Fazal Akbar.
      Cotton leaf curl disease (CLCuD), caused by viruses of the family Geminiviridae (genus Begomovirus), is of great concern for cotton production worldwide. The aim of the study was to characterize and quantify the worldwide scientific output of CLCuD research using bibliometric analysis. PubMed, Google Scholar and Scopus search engines were used to extract available data from 1901 to July 2017. A total of 854 CLCuD-related published documents were identified. Most of the documents were published in the form of original research articles (644, 75.4 %) and English was the main language of publication (807, 94 %). The results demonstrate that the study of CLCuD exhibits an overall increasing trend from 1991 to 2017, with the highest number of articles published in 2013. The top 10 countries in terms of absolute research output (number of publications) on this subject were Pakistan (217; 25.40%), India (161; 18.85%), the United States of America (USA; 122; 14.85%), China (85; 9.95%), United Kingdom (57; 6.67%), Sudan (31; 3.62%), Israel (14; 1.63%), Spain (13; 1.52%), Australia (11; 1.28%), Saudi Arabia (9; 1.05%) and Iran (9; 1.05%). Pakistan's most important collaborator was United States of America, followed by China. Noteworthy, not one of the papers listed here was the result of scientific collaboration between India and Pakistan. The total number of citations for all the publications was 3174, with an average of 3.71 citations per publication. The h-index for all extracted data related to CLCuD was 91. The top h-index was achieved by Pakistan (54) followed by the United Kingdom (43), the USA (41) and India (39). The National Institute for Biotechnology and Genetic Engineering (NIBGE), Faisalabad, ranked the first in the top 10 list of the most productive institutes. This bibliometric analysis highlights the leading role of Pakistan, India and the USA in research on CLCuD and points out that the initiation of a collaboration between Pakistan and India may have a significant impact on the research output and progress.

    Does academic authorship reflect gender bias in pediatric surgery? An analysis of the Journal of Pediatric Surgery, 2007-2017.
    Alexandra F Marrone, Loren Berman, Mary L Brandt, David H Rothstein.
       BACKGROUND: Gender representation in academic publications has been considered a surrogate for gender equity in medicine, although this concept has not been evaluated in pediatric surgery.
    METHODS: First and last author genders for Journal of Pediatric Surgery articles from United States and/or Canadian institutions (2007, 2012, 2017) were identified. These data were compared to gender proportions for applicants to and matriculants in pediatric surgery fellowships as well as among American Pediatric Surgical Association (APSA) members.
    RESULTS: Authorship gender was identified for 632/640 primary articles (98.8%). From 2007 to 2017, the proportion of women as first authors increased from 33.0% to 53.9% (p < 0.001) and as last authors from 16.2% to 26.4% (p = 0.01). The proportion of women fellowship applicants rose from 35.9% to 57.6% (p < 0.001); among those who successfully matched the rise was nonlinear (20.5%-34.0%, p = 0.16). APSA junior and senior women membership proportions rose during the study period [from 28.1% to 43.4% (p = 0.06 for linear trend) and 17.9% to 24.4% (p = 0.005 for linear trend), respectively].
    CONCLUSIONS: Over the past decade, the overall proportion of women authors in a leading academic pediatric surgery journal has increased significantly, although representation among last authors remains disproportionately low. The numbers of women applicants to pediatric surgery fellowship increased but there was not a concordant rise in the number of women accepted into training positions.

    The evolution of hypospadias publications: A bibliometric approach.
    Gül Doğan, Hülya İpek.
       BACKGROUND/OBJECTIVE: Although the increasing prevalence of hypospadias has been reported in many countries, there is a lack of bibliometric studies that make a holistic assessment of the publications about this issue. This study aims to make a holistic evaluation, latest developments, and trend topics about hypospadias publications between 1980 and 2018 through bibliometric analysis.
    METHODS: All the publications about hypospadias published in the Web of Science index between 1980 and 2018 were downloaded and analyzed using bibliometric methods. The Spearman's correlation coefficient was utilized to analyze the correlations between economic productivity and performance of the countries on hypospadias. Linear regression analysis was performed to estimate the number of publications for the following years.
    RESULTS: Bibliometric analyses were performed with 1940 articles. With 527 (27.2%) publications, the USA was the country that made the most contribution to the literature. The top active 3 journals were the Journal of Urology, Journal of Pediatric Urology, and Urology. A high correlation was detected between hypospadias publication productivity and GDP (r=0.791, p<0.001). The regression analysis results showed that the expected number of articles to be produced was 95 (75-116) for 2019 and 106 (47-164) for 2024.
    CONCLUSIONS: This study provides a holistic evaluation of the articles about hypospadias, which is an anomaly that should be repaired and treated with surgery due to its potential problems for the children at kindergarten and school age. Increasing the collaboration between especially developing countries and research in different countries with samples from different communities through multidisciplinary studies are recommended.

    Necati Enver, Akın Şahin, Said Sönmez, Semra Demokan.
       OBJECTIVES: The number of citations an article receives is an important indication of its impact. The main objectives of this investigation provide readers with a practical guide in evaluating head and neck oncology literature and determine the characteristics of trends in ORL.
    METHODS: This was a retrospective bibliometric analysis that did not involve human participant. The Thomson Reuters Web of Science was searched to determine the citations of all published HNO articles. Most cited 300 article analyzed and a total of 100 articles were included in our investigation under the topic search "Head AND NECK AND (cancer OR carcinoma OR oncology)." Articles include malignancies other than head and neck are excluded. The top 100 cited articles were selected and analyzed by 2 independent investigators. Country, Institution, First Author, Journal name, study design, cites per year information gathered and analyzed.
    RESULTS: The journal with the highest number of top 100 cited articles was New England Journal Of Medicine with 19 paper, followed by The Journal of Clinical Oncology(17) and Cancer Research (12). The top article on the list (Radiotherapy plus cetuximab for squamous cell carcinoma of the head and neck-NEJM) has 2243 citations. A statistically significant association was found between the journal impact factor and the number of top 100 cited articles (P < .05). The United States had the highest number of articles (63). John Hopkins is differed from other institutions with 15 contributing articles.
    CONCLUSION: Our analysis provides an insight into the citation frequency of top cited articles published in HNO to help recognize the quality of the works, discoveries and the trends steering the study of HNO. This is also a modern reading list for young HNO scientist.

    Trends in Female Authorship in High Impact Surgical Journals Between 2008 and 2018.
    Kamber L Hart, Laura T Boitano, Adam Tanious, Mark F Conrad, Matthew J Eagleton, Keith D Lillemoe, Roy H Perlis, Sunita D Srivastava.
       OBJECTIVE: This study evaluates the distribution of authorship by sex over the last 10 years among the top 25 surgical journals.
    SUMMARY OF BACKGROUND DATA: Despite an increase in women entering surgical residency, there remains a sex disparity in surgical leadership. Scholarly activity is the foundation for academic promotion. However, few studies have evaluated productivity by sex in surgical literature.
    METHODS: Original research in the 25 highest-impact general surgery/subspecialty journals were included (1/2008-5/2018). Journals with <70% identified author sex were excluded. Articles were categorized by sex of first, last, and overall authorship. We examined changes in proportions of female first, last, and overall authorship over time, and analyzed the correlation between these measurements and journal impact factor.
    RESULTS: There were 71,867 articles from 19 journals included. Sex was successfully predicted for 87.3% of authors (79.1%-92.5%). There were significant increases in the overall percentage of female authors (β = 0.55, P < 0.001), female first authors (β = 0.97, P < 0.001), and female last authors (β = 0.53, P < 0.001) over the study period. Notably, all cardiothoracic subspecialty journals did not significantly increase the proportion of female last authors over the study period. There were no correlations between journal impact factor and percentage of overall female authors (rs = 0.39, P = 0.09), female first authors (rs = 0.29, P = 0.22), or female last author (rs = 0.35, P = 0.13).
    CONCLUSIONS: This study identifies continued but slow improvement in female authorship of high-impact surgical journals during the contemporary era. However, the improvement was more apparent in the first compared to senior author positions.

    The Past, Present and Future of Literature Pertaining to Betel (Areca) Nut: A Citation Analysis.
    Mohit Vashney, Arpit Parmar, Ashwani Kumar Mishra.
      Objective and method: Betel (areca) nut has recently received interest from researchers and policy makers for its role as a psychoactive substance. It was historically limited to Asia-pacific region, but with the advent of globalization, it has become an equally challenging public health problem across the globe. Previously published literature can give us valuable insights in terms of historical interest and understanding related to betel nut. With the expansion of biomedical research a huge number of articles have been published on the same. In terms of understanding the impact of an article, citations are considered a proxy estimate measure. Thus we decided to analyze the top 100 cited articles (till November 2018) related to betel nut. The search in Google scholar database was done with the help of freely available software, Publish or Perish. Results: Overall we found that most articles were published from the fields of dentistry and oncology, with relatively minimal contribution from the field of Addiction Psychiatry. Hence, most articles have addressed the issue of epidemiology and mechanism with lesser share of treatment related publications. Various important information related to these articles have been discussed including the institutions, countries, journals and impactful authors in the field. Subsequently, original research articles are further classified into descriptive/epidemiology, mechanism, management, scale/measurement, imaging and medical psychiatry. Importance: This citation analysis provides valuable information with regards to the emphasis of researchers in the field, and areas where more emphasis is required from contemporary world.

    Knowledge Mapping of Drug-Induced Liver Injury: A Scientometric Investigation (2010-2019).
    Lixin Ke, Cuncun Lu, Rui Shen, Tingting Lu, Bin Ma, Yunpeng Hua.
       Background: Drug-induced liver injury (DILI) is a common adverse event, which compromises the safety of numerous drugs, poses a significant risk to patient health, and enhances healthcare expenditures. Many articles have been recently published on DILI related research, though no relevant scientometric study has been published yet. This scientometric study was aimed at comprehensively analyzing the knowledge base and emerging topics on DILI.
    Methods: The articles and reviews related to DILI, published from 2010 to 2019 in the Web of Science Core Collection (WoSCC), were retrieved on March 15, 2020, using relevant keywords. Four different scientometric software (HistCite, VOSviewer, CiteSpace, and R-bibliometrix) was used to conduct this scientometric study.
    Results: A total of 1,995 publications were retrieved (including 1,550 articles and 445 reviews) from 592 academic journals with 56,273 co-cited references in 10 languages by 2,331 institutions from 79 countries/regions. The majority of publications (n = 727, 36.44%) were published in the United States, and the University of North Carolina contributed the most publications (n = 89, 4.46%). The most productive academic journal on DILI was the Toxicological Sciences [n = 79, 3.96%; impact factor (IF) 2018 = 3.564], and Hepatology was the first co-cited journal (n = 7,383, IF 2018 = 14.971). Fontana RJ and Teschke R may have significant influence on DILI research, with more publications (n = 46; n = 39) and co-citations (n = 382; n = 945). Definition, incidence rate or clinical characteristics, etiology or pathogenesis (such as the character of the innate immune system, the regulation of cell-death pathways, and susceptible HLA-B*5701 genotype), identification of main drugs and causality assessment (criteria and methods) were the knowledge base for DILI research. Exploring the microscopic mechanism (such as the organelle dysfunction and cytotoxicity induced by drugs, and exploration of role of neutrophils in DILI using mouse models) and developed newer approaches to prevent DILI (such as the prospective HLA-B*5701 screening and in vitro approaches for assessing the potential risk of candidate drugs for DILI) were the recent major topics for DILI research.
    Conclusion: This scientometric study comprehensively reviewed the publications related to DILI during the past decade using quantitative and qualitative methods. This information would provide references for scholars, researching on DILI.

    Cristian Morán-Mariños, Carlos J Toro-Huamanchumo, Josmel Pacheco-Mendoza.
       OBJECTIVE: To analyse the scientific production and collaboration networks on publications in systemic lupus erythematosus in Latin America.
    MATERIALS AND METHODS: Bibliometric study between 1982 and 2018 of journals indexed in Scopus. Data were analysed by annual production and a co-occurrence analysis of the collaboration between countries with VOSviewer was plotted.
    RESULTS: 3,843 related documents on systemic lupus erythematosus were recorded between 1982 and 2018 in Scopus. An increasing trend was observed, with a significant increase in the last 20 years, the original articles being the highest percentage (75.4%). Eleven Latin American countries were identified in collaboration with 29 extra-regional countries, with Brazil, Mexico and Argentina having the highest production and scientific collaboration, mainly with the United States and Spain.
    CONCLUSION: In Latin America, there is a sustained increase in research on systemic lupus erythematosus. Brazil and Mexico generated more than half the publications and are the main collaboration network together with Argentina.

    Fifty Years of Accident Analysis & Prevention: A Bibliometric and Scientometric Overview.
    Xin Zou, Hai L Vu, Helai Huang.
      Accident Analysis & Prevention (AA&P) is a leading academic journal established in 1969 that serves as an important scientific communication platform for road safety studies. To celebrate its 50th anniversary of publishing outstanding and insightful studies, a multi-dimensional statistical and visualized analysis of the AA&P publications between 1969 and 2018 was performed using the Web of Science (WoS) Core Collection database, bibliometrics and mapping-knowledge-domain (MKD) analytical methods, and scientometric tools. It was shown that the annual number of AA&P's publications has grown exponentially and that over the course of its development, AA&P has been a leader in the field of road safety, both in terms of innovation and dissemination. By determining its key source countries and organizations, core authors, highly co-cited published documents, and high burst-strength publications, we showed that AA&P's areas of focus include the "effects of hazard and risk perception on driving behavior", "crash frequency modeling analysis", "intentional driving violations and aberrant driving behavior", "epidemiology, assessment and prevention of road traffic injuries", and "crash-injury severity modeling analysis". Furthermore, the key burst papers that have played an important role in advancing research and guiding AA&P in new directions - particularly those in the fields of crash frequency and crash-injury severity modeling analyses were identified. Finally, a modified Haddon matrix in the era of intelligent, connected and autonomous transportation systems is proposed to provide new insights into the emerging generation of road safety studies.

    Bibliometric analysis of adverse drug reactions and pharmacovigilance research activities in Nepal.
    Sunil Shrestha, Krisha Danekhu, Bhuvan Kc, Subish Palaian, Mohamed Izham Mohamed Ibrahim.
       Background: Bibliometric analyses have been used previously to study the measures of quality and impact of research performed in several health-related areas such as adverse drug reactions (ADRs) and pharmacovigilance (PV), etc. This method can assess the research performance of publications quantitatively and statistically. There is no evidence of bibilometric studies analyzing ADRs and PV from Nepal. Therefore, the present study aimed to assess scientific output on ADRs and PV-related research activities in Nepal using a bibliometric analysis of publications from 2004 January to December 2018, that is, 15 years.
    Methods: A systematic search was conducted in PubMed, Web of Science, Google Scholar, Scopus and Nepal Journal Online (NepJOL) databases. 'Adverse Drug Reactions' or 'ADRs' or 'ADR' or 'Adverse drug reaction' or 'AE' or 'Adverse Event' or 'Drug-Induced Reaction' or 'Pharmacovigilance' or 'PV' and 'Nepal'. The search covered 15 years (January 2004 to December 2018) of study on ADRs and PV in Nepal. Only articles retrieved from databases were included, whereas published/unpublished drug bulletins, pharmacy newsletters and thesis were excluded. The articles thus retrieved were recorded, and thereafter analyzed. Word count code was used for the analysis of keywords used in the retrieved articles.
    Results: A total of 124 articles were retrieved, with the highest rate of publications in 2006 and 2007, with 16 papers each. Among the articles, 10 (8.1%) were published in Kathmandu University Medical Journal (KUMJ). Single papers were published in 38 different journals. Brief reports (1.6%), case reports (31.2%), case series (0.8%), education forums (0.8%), letters to the editor (5.6%), original research articles (41.9%), review articles (9.7%), short communications and short reports (8.1%) on ADRs and PV were recorded. Out of 124 papers, 52 (41.9%) were original research publications. The majority (74.1%) of research was done in the category of ADR incidence, types, prevention, and management, followed by policy and suggestions for strengthening national and regional pharmacovigilance centers of Nepal (14.5%).
    Conclusions: During the study years, there was an increase in scientific publications on drug safety. A total of 124 published articles were found during bibliometric analysis of ADRs and PV research activities in Nepal.

    Future trends and guidance for the triple bottom line and sustainability: a data driven bibliometric analysis.
    Ming-Lang Tseng, Chia-Hao Chang, Chun-Wei Remen Lin, Kuo-Jui Wu, Qing Chen, Li Xia, Bing Xue.
      This study conducts a comprehensive literature review of articles on the triple bottom line (TBL) published from January 1997 to September 2018 to provide significant insights and support to guide further discussion. There were three booms in TBL publications, occurring in 2003, 2011, and 2015, and many articles attempt to address the issue of sustainability by employing the TBL. This literature analysis includes 720, 132, and 58 articles from the Web of Science (WOS), Inspec, and Scopus databases, respectively, and reveals the gaps in existing research. To discover the barriers and points of overlap, these articles are categorized into six aspects of the TBL: economic, environmental, social, operations, technology, and engineering. Examining the top 3 journals in terms of published articles on each aspect reveals the research trends and gaps. The findings provide solid evidence confirming the argument that the TBL as currently defined is insufficient to cover the entire concept of sustainability. The social and engineering aspects still require more discussion to support the linkage of the TBL and to reinforce its theoretical basis. Additionally, to discover the gaps in the data sources, theories applied, methods adopted, and types of contributions, this article summarizes 82 highly cited articles covering each aspect. This article offers theoretical insights by identifying the top contributing countries, institutions, authors, keyword networks, and authorship networks to encourage scholars to push the current discussion further forward, and it provides practical insights to bridge the gap between theory and practice for enhancing the efficiency and effectiveness of improvements.

    Evaluating "startup readiness" for researchers: case studies of research-based startups with biopharmaceutical research topics.
    Tomotaka Goji, Yuki Hayashi, Ichiro Sakata.
      For research domains such as life sciences, which pursue fundamental scientific understanding and applications intended for immediate use, academic entrepreneurship has played a pivotal role in commercialization. This paper presents an evaluation method of researchers related to user-inspired fundamental research, using global databases of startup finances and academic research papers of "startup readiness." Case studies of startups related to biopharmaceutical research topics suggest that the biopharmaceutical field has rich opportunities stemming from scientific research, commercialization, and entrepreneurship. This evaluation method sorts specific industry segments by which financing activities are active, and by which related growing research topics attract increased academic attention. We constructed networks of author citation and co-authorship from paper citation networks related to research topics in industry segments in the biopharmaceutical domain. Results obtained across all research topics we surveyed demonstrated that authors in the top 10% of degree centrality ranking in both networks are far more likely to be startup participants than other authors. Our computational approach might provide convenient, dynamic, global, and real-time understanding of the "startup readiness" of researchers working with research topics for which academic attention is emerging in actively financed biopharmaceutical fields.

    Global trends and prospects in microplastics research: A bibliometric analysis.
    Ying Zhang, Shengyan Pu, Xue Lv, Ya Gao, Long Ge.
      Microplastic pollution is a global enviromental issues. This is the first time in recent decades that quantitative and qualitative evidence from bibliometrics and Altmetric has been used to conduct an in-depth statistical analysis of global microplastics research knowledge and demonstrate research progress, trends and hotspots. We comprehensively searched the Web of Science Core Collection scientific database from its inception (1986) to September 21, 2019. The study shown that the number of papers on microplastics has increased significantly since 2011. Worldwide, researchers in the field come mostly from Western Europe, mainly spread in the UK, Netherlands and Belgium. With the exception of China, the contribution of developing countries was very limited. Moreover, this study systematically elaborated the hotspots in this field (especially in ecological toxicity and human health risks). The results shown that research on marine systems and marine plankton is still dominant. Since human beings are the ultimate consumers of the food chain, microplastics may have potential effects on the human respiratory system and gastrointestinal tract. Towards that end, some topics and perspectives are noted that could indicate the current scientific hotspots and guide future research directions.

    Integrated Plastic Surgery Match: Trends in Research Productivity of Successful Candidates.
    Ledibabari M Ngaage, Adekunle Elegbede, Katie L McGlone, Brooks J Knighton, Carisa M Cooney, Damon S Cooney, Scott D Lifchez, Sheri Slezak, Yvonne M Rasko.
       BACKGROUND: Plastic surgery continues to be one of the most competitive specialties in the residency match. Research productivity is a key component of the selection process. Nevertheless, potential applicants have a poor understanding of the strength of their research credentials in comparison to other applicants.
    METHODS: The authors identified successful applicants from the 2012 to 2017 integrated plastic surgery residency application cycles. The authors performed a bibliometric analysis of these residents using Scopus, PubMed, and Google Scholar to identify published articles at the time of application. The authors then calculated the h-index of each applicant at the time of application.
    RESULTS: The authors included 829 integrated residents. The median h-index was 0 (interquartile range, 0 to 3) and the median number of publications was 2 (interquartile range, 0 to 5) for all applicants. The proportion of applicants with at least one publication at the point of application increased significantly over time (60 percent in 2012 versus 76 percent in 2017; p = 0.0072). In addition, the number of publications per applicant increased over time (one in 2012 versus two in 2017; p = 0.0005), as did h-index (0 in 2012 versus 1 in 2017; p = 0.0015). Strikingly, the number and percentage of review articles among applicants increased significantly over this time frame (9 percent versus 14 percent; p = 0.0299).
    CONCLUSIONS: The increasing level of academic productivity among applicants may reflect the increasing competitiveness of the integrated plastic surgery residency application process. As the pressure to compete for a training position increases, students may seek faster-to-publish articles to gain an edge.

    Measuring researchers' potential scholarly impact with structural variations: Four types of researchers in information science (1979-2018).
    Jianhua Hou, Xiucai Yang, Chaomei Chen.
      We propose a method to measure the potential scholarly impact of researchers based on network structural variations they introduced to the underlying author co-citation network of their field. We applied the method to the information science field based on 91,978 papers published between 1979 and 2018 from the Web of Science. We divided the entire period into eight consecutive intervals and measured structural variation change rates (ΔM) of individual authors in corresponding author co-citation networks. Four types of researchers are identified in terms of temporal dynamics of their potential scholarly impact-1) Increasing, 2) Decreasing, 3) Sustained, and 4) Transient. The study contributes to the understanding of how researchers' scholarly impact might evolve in a broad context of the corresponding research community. Specifically, this study illustrated a crucial role played by structural variation metrics in measuring and explaining the potential scholarly impact of a researcher. This method based on the structural variation analysis offers a theoretical framework and a practical platform to analyze the potential scholarly impact of researchers and their specific contributions.

    Gender and Authorship in Pediatric Critical Care Randomized Control Trials.
    Grace M Xu, Samara Zavalkoff, Saskia N de Wildt, Mark Duffett.
       OBJECTIVES: To examine the gender distribution of authorship of pediatric critical care randomized control trials.
    DATA SOURCES: The 415 randomized control trials in pediatric critical care published before 2019.
    STUDY SELECTION: We included all randomized control trials enrolling children in a PICU. We used PICUtrials.net, which uses comprehensive search strategies of multiple databases, to identify published randomized control trials.
    DATA EXTRACTION: We manually extracted the name and profession of each listed author from each publication and classified each author as male or female based on their name.
    RESULTS: We included 2,146 authors and were able to classify 1,888 (88%) as men or women. Overall, 38% of authors were women, this varied with the authorship position: 37% of first, 38% of middle, and 25% of last authors were women (p < 0.001). The three most common professions were physician (63%), nonclinician (11%), and nurse (6%)-of which 30%, 45%, and 97%, respectively, were women. The percentage of female authorship overall has increased from 28% in 1985-1989 to 39% in 2015-2018 (p for trend = 0.004). There were no significant differences in the characteristics of randomized control trials published with a female first or last author versus those with both male first and last authors with respect to the median number of children randomized (60 vs. 50; p = 0.41), multicentred trials (17% vs. 24%; p = 0.12), trials at low risk of bias (50% vs. 66%; p = 0.26), reporting any funding (55% vs. 51%; p = 0.66), or median number of citations per year (1.5 vs. 2.4; p = 0.09).
    CONCLUSIONS: Although increasing over time, the percentage of researchers publishing pediatric critical care randomized control trials who are women still lags behind the percentage clinicians who are women. Trials that female researchers publish are similar in characteristics and impact as male researchers. Further work should identify barriers to gender diversity and potential solutions in pediatric critical care research.

    Are We Conditioning EBM Researchers to be Innovative or Narrow?
    Samuel Seery.
      This short essay considers preferential publication and impact factor as stimuli, instrumentally conditioning medical researchers. The author postulates that publication houses emphasising publication of the highest levels of evidence (ie, meta-analyses) at the detriment of other levels of evidence, is inadvertently guiding researchers to overlook necessary research for more individualised care. The author recommends preferential publication and impact factor should be openly discussed by medical educators to ensure we are training researchers to conduct meaningful, high quality, innovative research.

    A cross-sectional analysis of self-reported scholarly publications among United States pharmacy practice faculty.
    Kacey Hight, Nalin Payakachat, Melanie Reinhardt, Amy M Franks.
       INTRODUCTION: The objectives of this study were to provide an estimate of self-reported peer-reviewed publications and evaluate characteristics associated with publication rates among pharmacy practice faculty within United States (US)-based colleges and schools of pharmacy.
    METHODS: An online survey instrument was distributed to pharmacy practice faculty via email listserv. Information regarding faculty members' publication histories, faculty position, institutional characteristics, and faculty demographic characteristics was gathered. Descriptive statistics were used to characterize participants, and t-tests and analysis of variance were used for comparisons among groups.
    RESULTS: Two hundred and nine pharmacy practice faculty were included. The majority were female (67%), white (81%), and from public institutions (66%). Academic ranks were well-represented. Reporting higher percent time spent in research, employment at public institutions, and having earned a doctor of philosophy (PhD) degree were all significantly associated with higher total number of publications and a higher annualized publication rate. Tenure track faculty who were not yet tenured had higher annual publication rates than faculty who were tenured or in non-tenure track positions. The overall annual publication rate was 2.0 ± 2.1 publications per year.
    CONCLUSIONS: Characteristics such as being in a tenure track position, holding a PhD, spending more time in research, and employment within a public institution were all associated with a higher publication rate. These self-reported data from pharmacy practice faculty also indicate an increase in the average number of scholarly publications per year from previously reported estimates.

    Trends in Research and Graduate Programs in Schools and Colleges of Pharmacy, Part 1: Programs.
    Lisa Lebovitz, Peter W Swaan, Natalie D Eddington.
      Objective. To examine the landscape of research and graduate education nationally and within schools and colleges of pharmacy. This report is part 1 of a three-part series and focuses on graduate programs' research funding and science faculty composition and diversity. Findings. Between FY2008 and FY2017, the number of full-time faculty members in schools and colleges of pharmacy increased 36%. The number of pharmacy schools with National Institutes of Health (NIH) awards increased by 15%, while NIH grants per faculty principal investigator (PI) increased by 31%. However, unadjusted for inflation, the mean NIH dollar amount per-faculty member PI increased just 14% and the mean NIH dollar amount per-school declined 7%, indicating that number of funded faculty outpaced dollars available. Proportionately, the percentage of science faculty members at pharmacy schools decreased from 47% to 43%. Only 15 public, research-intensive schools and colleges of pharmacy received more than half of the combined FY2017 NIH funding and total funding, while all other public and private schools and colleges of pharmacy shared the remaining funds. Interdisciplinary programs are developing slowly, and may help to diversify and increase future funding. Proportions of tenured and tenure-track positions are declining, but biological sciences and social and administrative sciences disciplines are growing and women faculty are making significant gains in these fields and at the assistant professor rank. Summary. Research-intensive schools and colleges of pharmacy are best-positioned to lead the academy to reframe graduate education to build interdisciplinary team skills and attract more diverse funding and science faculty members.

    Research methodology and characteristics of journal articles with original data, preprint articles and registered clinical trial protocols about COVID-19.
    Mahir Fidahic, Danijela Nujic, Renata Runjic, Marta Civljak, Filipa Markotic, Zvjezdana Lovric Makaric, Livia Puljak.
       BACKGROUND: The research community reacted rapidly to the emergence of COVID-19. We aimed to assess characteristics of journal articles, preprint articles, and registered trial protocols about COVID-19 and its causal agent SARS-CoV-2.
    METHODS: We analyzed characteristics of journal articles with original data indexed by March 19, 2020, in World Health Organization (WHO) COVID-19 collection, articles published on preprint servers medRxiv and bioRxiv by April 3, 2010. Additionally, we assessed characteristics of clinical trials indexed in the WHO International Clinical Trials Registry Platform (WHO ICTRP) by April 7, 2020.
    RESULTS: Among the first 2118 articles on COVID-19 published in scholarly journals, 533 (25%) contained original data. The majority was published by authors from China (75%) and funded by Chinese sponsors (75%); a quarter was published in the Chinese language. Among 312 articles that self-reported study design, the most frequent were retrospective studies (N = 88; 28%) and case reports (N = 86; 28%), analyzing patients' characteristics (38%). Median Journal Impact Factor of journals where articles were published was 5.099. Among 1088 analyzed preprint articles, the majority came from authors affiliated in China (51%) and were funded by sources in China (46%). Less than half reported study design; the majority were modeling studies (62%), and analyzed transmission/risk/prevalence (43%). Of the 927 analyzed registered trials, the majority were interventional (58%). Half were already recruiting participants. The location for the conduct of the trial in the majority was China (N = 522; 63%). The median number of planned participants was 140 (range: 1 to 15,000,000). Registered intervention trials used highly heterogeneous primary outcomes and tested highly heterogeneous interventions; the most frequently studied interventions were hydroxychloroquine (N = 39; 7.2%) and chloroquine (N = 16; 3%).
    CONCLUSIONS: Early articles on COVID-19 were predominantly retrospective case reports and modeling studies. The diversity of outcomes used in intervention trial protocols indicates the urgent need for defining a core outcome set for COVID-19 research. Chinese scholars had a head start in reporting about the new disease, but publishing articles in Chinese may limit their global reach. Mapping publications with original data can help finding gaps that will help us respond better to the new public health emergency.

    Mental Health and Well-Being of University Students: A Bibliometric Mapping of the Literature.
    Daniel Hernández-Torrano, Laura Ibrayeva, Jason Sparks, Natalya Lim, Alessandra Clementi, Ainur Almukhambetova, Yerden Nurtayev, Ainur Muratkyzy.
      The purpose of this study is to map the literature on mental health and well-being of university students using metadata extracted from 5,561 journal articles indexed in the Web of Science database for the period 1975-2020. More specifically, this study uses bibliometric procedures to describe and visually represent the available literature on mental health and well-being in university students in terms of the growth trajectory, productivity, social structure, intellectual structure, and conceptual structure of the field over 45 years. Key findings of the study are that research on mental health and well-being in university students: (a) has experienced a steady growth over the last decades, especially since 2010; (b) is disseminated in a wide range of journals, mainly in the fields of psychology, psychiatry, and education research; (c) is published by scholars with diverse geographical background, although more than half of the publications are produced in the United States; (d) lies on a fragmented research community composed by multiple research groups with little interactions between them; (e) is relatively interdisciplinary and emerges from the convergence of research conducted in the behavioral and biomedical sciences; (f) tends to emphasize pathogenic approaches to mental health (i.e., mental illness); and (g) has mainly addressed seven research topics over the last 45 years: positive mental health, mental disorders, substance abuse, counseling, stigma, stress, and mental health measurement. The findings are discussed, and the implications for the future development of the field are highlighted.

    Use of AMSTAR-2 in the methodological assessment of systematic reviews: protocol for a methodological study.
    Cuncun Lu, Tingting Lu, Long Ge, Nan Yang, Peijing Yan, Kehu Yang.
       Background: Systematic reviews (SRs) with or without meta-analyses (MAs) are widely used in resolving questions in various healthcare areas (such as, traditional Chinese medicine, public health and surgery), and they are the cornerstone of evidence-based healthcare. However, the reliability of SRs is typically influenced by their methodological quality. AMSTAR (A Measurement Tool to Assess Systematic Reviews) and AMSTAR-2 tools can assess the methodological quality of SRs, and the use of AMSTAR has been investigated. However, AMSTAR-2 is now widely used to evaluate the methodological quality of SRs, but the use of AMSTAR-2 for determining the methodological quality of SRs has not yet been investigated and assessed thoroughly. Thus, we designed the present study to investigate the use of AMSTAR-2 in studies that assessed the methodological quality of a sample of SRs with the AMSTAR-2 and provide references to potential users of AMSTAR-2 tool.
    Methods: Four commonly used electronic databases including PubMed, EmBase, the Cochrane Library, and Web of Science will be searched following a comprehensive search strategy to identify and retrieve studies that have used AMSTAR-2 tool for evaluating the methodological quality of SRs. Two independent authors will retrieve bibliometric information and methodological data, including all author names, time of publication, and journal names, whether a specific score value was given for each item, and whether overall quality assessment was performed. Descriptive statistical analyses will be used to present the study results, e.g., frequencies and percentages, mean and standard deviation (SD) or median and interquartile range (IQR). In addition, subgroup analyses will be performed to identify the methodological differences (e.g., the reporting of study designs included in SRs) between overviews and methodological studies. The risk ratio (RR) with 95% confidence interval (95% CI) will be calculated to measure the methodological differences. Cytoscape 3.7.1 software tool will be used to construct collaboration network maps. Further, Microsoft Office Excel 2016 and Stata 12.0 will be used to manage and analyze data.
    Discussion: The results of this study will identify any gaps in the use of AMSTAR-2 and important bibliometric features, such as active researchers and journals, provide guidance to researchers in various healthcare areas (such as, traditional Chinese medicine and public health) for using AMSTAR-2 tool and help them in developing cooperation and submitting their manuscripts.

    Paradox in melanoma: more patients fewer publications.
    Faruk Tas, Kayhan Erturk.
      The incidence of melanoma has increased more dramatically than any other malignancy in the last years. In this study, we compared the numbers of publications between melanoma and other cancers over the last 20 years, and we aimed to understand the relationship between publications on melanoma and other cancers using publication rates and frequencies. We conducted a systematic search through PubMed using search terms 'melanoma' and 'cancer' to identify the numbers of publications on melanoma and other cancers. The numbers and life-time risk rates of both melanoma and other cancer patients over the years were obtained from 'Cancer Statistics' articles published annually by American Cancer Society. Both melanoma and other cancer related publications increased in number steadily at the same rate (3.01 times) and the ratio of melanoma-related publications to all cancer publications has not changed over the years: around 3.4% on average. The rates of melanoma increased more rapidly than those of other cancers; 2.02 and 1.44 times, respectively. Similarly, the incidence of melanoma among all malignancies has increased from 3.91 to 5.47%. The lifetime risk of developing cancer has stayed stable at around 40%, whereas the lifetime risk of developing melanoma has increased by 2.12 times over the years, from 1.47 to 3.1%. In conclusion, the increase in the melanoma-related publication numbers has failed short to meet the dramatic increment of melanoma patient numbers. We believe that more publications are required according to the rising incidence of the disease.
