       OBJECTIVE: To explored the progress of intensive care unit (ICU) delirium between 2010 and 2020 based on knowledge visualization analysis.
    METHODS: The literatures related to ICU delirium included in Web of Sciences (WOS) and China National Knowledge Infrastructure (CNKI) databases from 2010 to 2020 were collected. A bibliometric analysis was performed. The growth trend was showed by Excel 2019 software. The information about country, institution and author were extracted by VOSviewer 1.6.15 for generating cooperative network, to find the main research power and each cooperative relation. At the same time, Citespace 5.0.R1 was used to analyze those high frequency keywords and bursting keywords and build the map of co-citation reference, in order to explore the evolution of research in the field of ICU delirium and the hotspots about this field in recent 10 years.
    RESULTS: A total of 1 102 Chinese journal articles and 2 422 English "Articles" or "Reviews" from 2010 to 2020 were collected preliminarily, and the number of published literatures increased steadily. In the respect of quality, the impact factors of most articles were concentrated between 2 and 3, and the literatures with impact factor over 5 accounted for 27.9% (337/1 209). According to the knowledge visualization analysis, the United States published most of the related articles (total 1 152) in this field, while the England and Canada ranked second and third respectively, totaling 220 and 204. In terms of the distribution of research institutions, the Vanderbilt University School of Medicine was not only far ahead in the number of publication (n = 149), but more importantly, top three high-impact authors located in this institution. The amount of domestic publications was lower than developed countries, however, the burst index, which reflected the sudden increase, ranked first (7.09), suggesting that the interest and investment of Chinese researchers was increasing recently. The most productive institution in China was Capital Medical University School of Nursing with totaling 23 articles. Wu Ying, who published most Chinese papers (n = 14), belongs to this institution. However, it was a pity that there was no large scientific community be constructed in China, and the cooperation between institutions was deficient. By generating the co-occuring keyword mapping, the research hotpots mainly focused on the prevention, treatment and prevention of delirium in mechanically ventilated patients, the effect of dexmedetomidine and exploring the risk factor of ICU delirium. Finally, the results of co-citation reference analysis showed that Cluster 4 (risk assessment) was still in the process of development, in hence it was the frontier in this domain.
    CONCLUSIONS: There was a big gap between China and leading countries in the field of ICU delirium research. The main research power was located in the United States, and the trending of future studies mainly focus on delirium-related risk assessment.

    [Regional System for Vaccines (SIREVA), laboratory surveillance and vaccine development for Streptococcus pneumoniae: bibliometric analysis, 1993-2019].
    José Luis Di Fabio, Clara Inés Agudelo, Elizabeth Castañeda.
       Objective: To measure through bibliometric analysis the productivity, visibility and impact of the Regional System for Vaccines (SIREVA, a project by the Pan American Health Organization), including its two components laboratory surveillance and vaccine development.
    Methods: Publications about laboratory surveillance and vaccine development were recovered from Scopus, including their references and citations, and their bibliometric indicators were analyzed. VOSviewer 1.6.13® was used to visualize the co-authorship networks, by country and authors, and to perform a cooccurrence analysis of terms included in the titles and abstracts of the publications.
    Results: The criteria for laboratory surveillance and vaccine development were met by 173 and 128 publications, respectively. Ten countries in the Region of the Americas were responsible for 90.8% of the publications on laboratory surveillance and 8 for all publications on vaccine development. The 10 most cited publications on laboratory surveillance and on vaccine development were included in 855 and 503 articles, respectively, the main authors being from Australia, Belgium, Brazil, China, Germany, the United Kingdom and the United States of America. Network building and visualization by author and country co-authors, and co-occurrence of terms showed networking and intraregional collaboration, and allowed for the follow-up of study areas and evolution over time.
    Conclusions: The bibliometric analysis allowed to objectively record the productivity and visibility of the Regional System for Vaccines for Streptococcus pneumoniae in the Region.

    Tingxiao Zhao, Jianjian Shen, Jun Zhang, Xueyu Hu, Kazuaki Morizane, Yazeng Huang, Haiyu Shao, Grant J Riew, Daniel K Riew.
       STUDY DESIGN: A bibliometric review of current literature.
    OBJECTIVE: The purpose of this study was to identify and analyze the 100 most cited articles in spinal disc arthroplasty (SDA) research.
    SUMMARY OF BACKGROUND DATA: In the last several decades, SDA has been widely performed all over the world, with increasing popularity of cervical disc arthroplasty (CDA). While there is a large number of articles on this topic, to our knowledge, there is no bibliometric analysis yet.
    METHODS: All databases from the Web of Science were searched in a three-step approach. The information of the 100 most cited studies was collected, including title, first and last author, year of publication, journal, total citations, geographic origin, subspecialty, and types of artificial intervertebral disc for further analysis.
    RESULTS: The 100 most-cited articles were published from 1966 to 2015 in 9 different journals and were cited from 66 to 346 times. A total of 11 countries contributed to the 100 articles and the United States topped the list, with 54 articles, followed by Germany and France, with 10 and 9 articles, respectively. There were more studies in CDA (n = 53) than lumbar disc arthroplasty (n = 35). Most of the studies reported clinical and radiographic outcomes (n = 33). The most productive periods were from 2006 to 2010. The majority of publications were in Spine, which published 43 articles. In total, twelve authors published more than two articles on the list.
    CONCLUSION: Of the top 100 most cited articles on SDA, cervical papers outnumbered lumbar articles and the US had 55 articles, with no other countries having more than 10. Our paper can help readers determine which of the thousands of articles on this topic are the most impactful and important ones to be familiar with.

    Yuetian Yu, Yujie Li, Zhongheng Zhang, Zhichun Gu, Han Zhong, Qiongfang Zha, Luyu Yang, Cheng Zhu, Erzhen Chen.
       Background: As a global pandemic, COVID-19 has aroused great concern in the last few months and a growing number of related researches have been published. Therefore, a bibliometric analysis of these publications may provide a direction of hot topics and future research trends.
    Methods: The global literatures about COVID-19 published between 2019 and 2020 were scanned in the Web of Science collection database. "COVID-19" "Novel Coronavirus" "2019-nCoV" and "SARS-CoV-2" were used as the keywords to reach the relevant publications. VOSviewer was applied to perform the bibliometric analysis of these articles.
    Results: Totally 3,626 publications on the topic of COVID-19 were identified and "COVID-19" with a total link strength of 2,649 appeared as the most frequent keyword, which had a strong link to "pneumonia" and "epidemiology". The mean citation count of the top 100 most cited articles was 96 (range, 26-883). Most of them were descriptive studies and concentrated on the clinical features. The highest-ranking journal was British medical journal with 211 publications and the most cited journal was Lancet with 2,485 citation counts. Eleven articles written by Christian Drosten from Berlin Institute of Virology have been cited for 389 times and 40 articles from Chinese Academy of Sciences have been cited for 1,597 times which are the most cited author and organization. The number of collaborators with China is 44 and the total link strength is 487. The main partners of China are USA, England and Germany. The published literatures have focused on three topics: disease management, clinical features and pathogenesis.
    Conclusions: The current growth trends predict a large increase in the number of global publications on COVID-19. China made the most outstanding contribution within this important field. Disease treatment, spike protein and vaccine may be hotspots in the future.

    Lydie A Lebrun-Harris, Sarika R Parasuraman, Candace Norton, Alicia A Livinski, Reem Ghandour, Stephen J Blumberg, Michael D Kogan.
       OBJECTIVE: Bibliometric analyses are commonly used to measure the productivity of researchers or institutions but rarely used to assess the scientific contribution of national surveys/datasets. We applied bibliometric methods to quantify the contributions of the National Survey of Children's Health (NSCH) and the National Survey of Children with Special Health Care Needs (NS-CSHCN) to the body of pediatric health-related research. We also examined dissemination to non-research audiences by analyzing media coverage of statistics and research produced from the surveys.
    METHODS: We conducted a search of the Web of Science database to identify peer-reviewed articles related to the NSCH and NS-CSHCN published between 2002 and 2019. We summarized information about citation counts, publishing journals, key research areas, and institutions using the surveys. We used the Lexis Advance database Nexis to assess media coverage.
    RESULTS: The publication set included 716 NSCH/NS-CSHCN journal articles published between 2002 and June 2019. These publications have in turn been cited 22,449 times, including in 1,614 review articles. Over 180 journals have published NSCH/NS-CSHCN articles, and the most commonly covered research areas are in pediatrics; public, environmental and occupational health; psychology; and health care sciences and services. Over 500 institutions have used NSCH/NS-CSHCN data to publish journal articles, and over 950 news media articles have cited statistics or research produced by the surveys.
    CONCLUSIONS: NSCH/NS-CSHCN data are widely used by government, academic, and media institutions. Bibliometric methods provide a systematic approach to quantify and describe the contributions to the scientific literature made possible with these data.

    Turki Elarjani, Othman T Almutairi, Modhi Alhussinan, Abdulelah Alturkistani, Fahad S Alotaibi, Mohammed Bafaquh, Fahad E Alotaibi.
       BACKGROUND: Craniosynostosis is the premature closure of cranial sutures and it continues to be a therapeutic challenge due to the diversity and complexity of the syndrome. Bibliometric analysis is a study of ranking citations and exploring the most impactful articles in a respective discipline. It also demonstrates the chronological trends of publications.
    METHODS: In May 2020, we performed a title-specific search of the Scopus database using "craniosynostosis" as our query term without publication date restrictions. The top 100 articles in craniosynostosis were retrieved and analyzed.
    RESULTS: The top 100 most-cited articles in craniosynostosis received a total 13,826 citations, and an average of 138 citations per paper. The publication dates ranged from 1920 to 2015, with a peak period of top publications between 1996 and 2005. The most common category is clinical, followed by neurogenetics. The top cited article received 540 citation counts and 19.29 citations per year. The USA was the most contributing country to the list. The Journal of Plastic and Reconstructive Surgery published the largest number of top cited articles. Neurosurgery as a specialty contributed to most articles in the list (27 articles). The institute who contributed the most was the Assistance Publique Hopitaux Paris.
    CONCLUSION: Bibliometric analysis in craniosynostosis revealed major trend changes of research over the years, with a focus on neurogenetics and the different types of surgical corrections. The current collection of highly cited publications may assist physicians in gaining a better understanding of the evidence-based approach in craniosynostosis.

    José Luis Aleixandre-Tudó, Máxima Bolaños-Pizarro, Jose Luis Aleixandre, Rafael Aleixandre-Benavent.
      The main objective of this investigation was to analyze the scientific production in global research on nanotechnology, integrating scientific production, funding of studies, collaborations between countries and the most cited publications. The source for obtaining the research papers for our analysis was the Science Citation Index Expanded from the Web of Science. A number of 3,546 documents were extracted during the period 1997-2018. Food Science & Technology, Chemistry (Applied and Analytical), Spectroscopy and Agriculture appeared as the main areas where the articles were published. Most prolific and cited journals were Analytical Methods stands, Journal of Agricultural and Food Chemistry and Food Chemistry (188). The co-word analysis showed the relationships between "nanoparticles", which is the central word, and "silver nanoparticles", "delivery systems" and "zinc-nanoparticles". The most productive countries were China (1089 papers), United States (523), Iran (427) and India (359). The main cited topics deal with the biomedical applications of nanoparticles, its synthesis from plants and its applications in food science. It highlights an important collaboration between institutions and countries. The availability of funding for research in nanotechnology was remarkable compared to other fields. The multidisciplinary of the nanotechnology field is one of the main features as well as one the of the central findings.

    Bibliometric analysis of global research output on antimicrobial resistance in the environment (2000-2019).
    Waleed M Sweileh, Ahmad Moh'd Mansour.
       Background: Antimicrobial resistance (AMR) is a global health threat that requires a "One Health" approach. Of the One Health triad, the environmental component is the most dynamic and most neglected. Therefore, the objective of the current study was to assess and analyze global research activity on AMR in the environment.
    Methods: This was a bibliometric descriptive study of publications on AMR in the environment. Publications were retrieved using SciVerse Scopus for the study period from 2000 to 2019. The search query was developed using terms and phrases related to the topic. The retrieved publications were analyzed for specific bibliometric indicators including annual growth, citation analysis, key players, research output for each world regions, research themes, and occurrences of different drug classes of antimicrobials. Visualization maps including research collaboration were created using VOSviewer program. The Hirsch (h) index was used to assess scientific impact.
    Results: There were 2611 research articles based on the implemented research query. The retrieved documents had an average of 22 citations per document and an h-index of 122. The annual number of publications showed a steep increase from 2011 to 2019. The major research themes in the field were (1) dissemination and abundance of antibiotic-resistant genes and (2) detection of bacterial strains or antibiotic residues in various environmental isolates. The bulk of the retrieved articles (n = 899; 34.4%) originated from the European region. China led with 598 (22.9%) documents. Four of the top 10 active institutions were in China. The top 10 active countries had relatively inadequate international research collaboration. The most commonly encountered antibiotic drug classes in the retrieved articles were penicillin/cephalosporin (n = 1152 occurrences). The most frequently encountered pathogen in the retrieved publications was E. coli (n = 666). The Science of the Total Environment journal was the most prolific journal with 139 (5.3%) publications.
    Conclusion: Scientific literature on the AMR in the environment has witnessed a steep growth lately with a leading role of China and Chinese institutions. Data on AMR in the environment need to be collected from all world regions including the Eastern Mediterranean and African regions through research collaboration and funding of research in this field.

    Global Trends of Botulinum Toxin Literature: A Bibliometric Analysis of Botulinum Toxin Publications Between 1975 and 2017.
    Engin Şenel, Ümran Muslu.
       Background: Botulinum toxin has been effectively used cosmetically and therapeutically for the last decades in a wide range of medical conditions. Although bibliometrics has been a popular and growing study area in recent years, medical literature lacks studies evaluating published botulinum toxin literature.
    Objective: The goal of our study was to evaluate bibliometric features and to perform a detailed trend analysis in the medical literature related to botulinum toxin.
    Materials and Methods: We analyzed all the published documents including the keywords "botulinum toxin" and "botulinum neurotoxin" and commercial brand names of botulinum toxin products between 1975 and 2017. We performed a detailed bibliometric and scientometric assessment in this field.
    Results: A total of 24,948 articles were retrieved from four databases provided by Web of Science, and most of which were original articles (76.19%). The United States ranked first and dominated literature with 8,729 documents (34.29%) followed by the United Kingdom, Germany, and Italy (14.61%, 11.18%, and 5.5%, respectively). The United Kingdom was detected to be the most productive country with the highest productivity (55.09) followed Switzerland, Denmark, and Germany (47.7, 34.01, and 33.98, respectively). The most studied area was neurology (56.1%) and University of California System was the most productive institution. We noted no correlation between publication number and citations by year.
    Conclusion: We found that all top 10 authors and institutions were from developed countries. Physician from developing and the least-developed countries should be supported to carry out novel studies on botulinum toxin.

    Articles with impact: insights into 10 years of research with machine learning.
    Stephan van der Zwaard, Arie-Willem de Leeuw, L Rens A Meerhoff, Sue C Bodine, Arno Knobbe.
      Worldwide scientific output is growing faster and faster. Academics should not only publish much and fast, but also publish research with impact. The aim of this study is to use machine learning to investigate characteristics of articles that were published in the Journal of Applied Physiology between 2009 and 2018, and characterize high-impact articles. Article impact was assessed for 4,531 publications by three common impact metrics: the Altmetric Attention Scores, downloads and citations. Additionally, a broad collection of (more than 200) characteristics was collected from the article's title, abstract, authors, keywords, publication, and article engagement. We constructed random forest (RF) regression models to predict article impact and articles with the highest impact (top-25% and top-10% for each impact metric), which were compared to a naïve baseline method. RF models outperformed the baseline models when predicting the impact of unseen articles (p<0.001 for each impact metric). Also, RF models predicted top-25% and top-10% high-impact articles with a high accuracy. Moreover, RF models revealed important article characteristics. Higher impact was observed for articles about exercise, training, performance and V̇O2max, reviews, human studies, articles from large collaborations, longer articles with many references and high engagement by scientists, practitioners and public or via news outlets and videos. Lower impact was shown for articles about respiratory physiology or sleep apnea, editorials, animal studies, and titles with a question mark or a reference to places or individuals. In summary, research impact can be predicted and better understood using a combination of article characteristics and machine learning.

    Determinants of Citation in Epidemiological Studies on Phthalates: A Citation Analysis.
    Miriam J E Urlings, Bram Duyx, Gerard M H Swaen, Lex M Bouter, Maurice P A Zeegers.
      Citing of previous publications is an important factor in knowledge development. Because of the great amount of publications available, only a selection of studies gets cited, for varying reasons. If the selection of citations is associated with study outcome this is called citation bias. We will study determinants of citation in a broader sense, including e.g. study design, journal impact factor or the funding source of the publication. As a case study we assess which factors drive citation in the human literature on phthalates, specifically the metabolite mono(2-ethylhexyl) phthalate (MEHP). A systematic literature search identified all relevant publications on human health effect of MEHP. Data on potential determinants of citation were extracted in duplo. Specialized software was used to create a citation network, including all potential citation pathways. Random effect logistic regression was used to assess whether these determinants influence the likelihood of citation. 112 Publications on MEHP were identified, with 5684 potential citation pathways of which 551 were actual citations. Reporting of a harmful point estimate, journal impact factor, authority of the author, a male corresponding author, research performed in North America and self-citation were positively associated with the likelihood of being cited. In the literature on MEHP, citation is mostly driven by a number of factors that are not related to study outcome. Although the identified determinants do not necessarily give strong indications of bias, it shows selective use of published literature for a variety of reasons.

    Global research trends on bioflocculant potentials in wastewater remediation from 1990 - 2019 using a bibliometric approach.
    Kunle Okaiyeto, Temitope Ekundayo, Anthony Okoh.
      The preference of biofloculants over chemical flocculants in water and wastewater remediation systems have gained wider attention due to their biodegradability, innocuousness, safety to human and environmental friendliness. The present study aimed to evaluate research outputs on bioflocculant potentials in wastewater remediation from 1990 - 2019 using bibliometric analyses. To the best of our knowledge, this is the first bibliometric report in bioflocculant research. The subject bibliometric dataset was extracted from the Web of Science Core Collection (WoSCC) and Scopus using the Boolean, "bioflocculant* and waste*" and analyzed for indicators such as a yearly trend, productivity (authors, articles, country, institution, and journal source), conceptual framework and collaboration network. We found 119 documents with 347 authors from 78 journal sources on the subject, an annual growth rate of 12.1%, and average citations/document of 15.08. Guo J. and Wang Y. were the top researchers with 15 and 12 outputs, respectively. China (42%) and South Africa (9.24%) ranked the top 2 dominant countries in the field. The top journals were Bioresource Technology (9 papers, 506 citations), Applied Microbiology and Biotechnology (5 papers, 268 citations), whereas, the top institution was Chengdu University of Information and Technology (n = 9 documents) followed by Sichuan Univ. Sci. & Engn, China (n = 8 documents). This study found that lack of intercountry collaboration and research funding adversely affects research participants in the field.

    Are UK and Ireland trauma and orthopaedic surgeons maintaining their research output?
    M Scotcher, A Asif, K Kulkarni.
       INTRODUCTION: Healthcare faces growing challenges. With reports of diminishing research output from the UK and Ireland in the leading surgical journals, this study aimed to ascertain whether this trend had been echoed in the trauma and orthopaedic literature.
    MATERIALS AND METHODS: Citable research output from the 10 globally leading trauma and orthopaedic journals was analysed from five individual years, over a 20-year period, to ascertain trends in absolute output, geographical mix, and level of evidence.
    RESULTS: The overall number of published articles fell by 14.5%. North America saw the greatest decline (-8.0%), followed by Japan (-5.6%) and Europe (-3.3%). The UK and Ireland (+2.9%) and the rest of the world (+13.9%) saw rising output. A decline in lower (levels IV and V) and a rise in higher (levels I, II and III) quality evidence was observed. The UK and Ireland had a greater proportion of higher-quality studies than North America and Japan, but lower than Europe and the rest of the world. The impact factor of the leading journal rose from 4.47 to 7.01.
    DISCUSSION: The research landscape has evolved, with leading journals placing greater emphasis on higher-quality evidence. UK and Irish research output remains stable, contributing 14% of the most highly cited publications in 2018, and challenging North America's dominance with a greater proportion of level I and II evidence in the leading journals.
    CONCLUSION: With the growing emergence of Europe and the rest of the world, UK and Irish authors must build upon the region's output despite political challenges such as Brexit. Increasing international collaboration will continue to play an important role.

    Chen-Yu Wang, Shi-Can Zhou, Xing-Wang Li, Bing-Hui Li, Jun-Jie Zhang, Zheng Ge, Quan Zhang, Jun-Hong Hu.
       BACKGROUND: Colorectal cancer is one of the most common cancers globally. In China, its prevalence ranks fourth and fifth among females and males, respectively. Presently, treatment of rectal cancer follows a multidisciplinary comprehensive treatment approach involving surgery, radiotherapy, chemotherapy, and targeted therapy. With deepening theoretical and molecular research on colorectal cancer, randomized controlled trials (RCTs) on colorectal cancer have made significant progress. However, many RCTs have shortfalls.
    AIM: To investigate the RCTs of global colorectal cancer spanning from 2008 to 2018. To provide suggestions for conducting Chinese RCTs of colorectal cancer.
    METHODS: PubMed and Web of Science databases were searched to obtain RCTs of colorectal cancer carried out between January 1, 2008, and January 1, 2018. The bibliometric method was used for statistical analysis of the publication years, countries/regions, authors, institutions, source journals, quoted times, key words, and authors.
    RESULTS: Colorectal cancer RCTs showed an upward trend between 2008 to 2018; the top 10 research institutions in the included literature were from the United States, the United Kingdom, and other countries with a high incidence of colorectal cancer. Most of the related research journals are sponsored by European and American countries. The 15 most cited studies involved international multicenter clinical research, having few participants from Chinese research institutions. Network visualization using key words showed that RCTs on colorectal cancer focus on screening, disease-free survival, drug treatment, surgical methods, clinical trials, quality of life, and prognosis. The result of the coauthorship network analysis showed that Chinese researchers are less involved in international exchanges compared to those from leading publication countries.
    CONCLUSION: High-quality RCTs are increasingly favored by leading international journals. However, there is still a large gap in clinical research between China and leading countries. Researchers should implement standardized and accurate clinical trials, strengthen international multicenter cooperation, and emphasize quality control.

    Female Authorship in Radiology: Trends in the Past Decade in CARJ.
    Nicole Li, Mostafa Alabousi, Michael N Patlas.
       PURPOSE: To identify trends in female authorship in the Canadian Association of Radiologists Journal (CARJ) from 2010 to 2019.
    METHODS: We retrieved papers published in the CARJ over a 10-year period, and retrospectively reviewed 602 articles. All articles except editorials and advertisements were included. We categorized the names of the first and last position authors as female or male and excluded articles that had at least one author of which gender was not known. We compared the trends in the first and last position authors of the articles from 2010 to 2019. For statistical analysis, logistic regression was performed with reported odds ratios (ORs), and a P value of <.05 was defined as statistically significant.
    RESULTS: Five hundred thirteen articles met inclusion criteria. Among them, 23 articles with a single author were classified as having only a first author. 39.8% (204/513) of first authors were female and 26.9% (132/490) of last authors were female. There has been an overall temporal increase in the odds of both the first and last author being female in CARJ publications (OR: 1.11, P = .034). Similarly, the odds a CARJ publication's first author being female increased over time (OR: 1.07, P = .033). Female last author did not predict female first author (OR: 1.48, P = .056). There was no association identified between female last author and year of publication (OR: 1.04, P = .225).
    CONCLUSION: There has been an overall increase in engagement of female authorship in CARJ.

    [Visual analysis of influenza treated by traditional Chinese medicine based on CiteSpace].
    Qianfei Wang, Chenxi Wang, Lijuan Wu, He Zhang, Haiyun Gao, Junhu Li, Fenqiao Chen.
       OBJECTIVE: To analyze the research status, research hotspots and frontier trends of traditional Chinese medicine (TCM) in the treatment of influenza in the past 20 years through the knowledge graph, so as to provide reference basis for further research.
    METHODS: The related literatures of TCM in the treatment of influenza were collected in China National Knowledge Infrastructure (CNKI) from 2000 to 2019. The relevant graphs of authors, research institutions and key words were drawn by CiteSpace 5.6, the distribution and cooperation of main research forces in this field were analyzed, and the research frontiers and hot spot information in this field were discussed.
    RESULTS: A total of 3 048 related literatures were obtained, involving 949 authors and 242 research institutions. The analysis of the number of articles showed that the volume of articles related to the treatment of influenza with TCM fluctuated greatly in the past 20 years, which was obviously affected by the sudden hot spots around 2010, but showed an overall upward trend, with an average annual volume of about 152 articles. The analysis of the author's cooperation map showed that a total of 77 core authors had published more than 5 articles, accounting for only 8.1% of all authors, and 5 authors had published more than 30 articles. Five major teams had been formed with Gu Ligang, Liu Qingquan, Lu Fangguo, Cui Xiaolan and Zhang Fengxue as the core. The analysis of the cooperation map of research institutions showed that the cooperation among institutions was not good, and only the scientific research institutes in Beijing and Guangzhou had formed a closely related cooperation network. The keyword co-occurrence map showed that 8 keywords appeared more than 100 times, especially ultra-high-frequency keywords, influenza virus ranked first (n = 518). There were 14 key nodes, such as influenza virus, TCM treatment, viral pneumonia and so on, which supported the current research field of TCM in the treatment of influenza. Fourteen clusters were formed to classify the current research hotspots, including the nomenclature of influenza, virus type, TCM treatment, western medicine knowledge, etc., and the map showed that the clustering was reasonable and the structure was significant. Timeline graph showed that parainfluenza virus, virus disease, pharmacodynamics, heat-clearing and detoxifying drugs, bacteriostasis and experimental research had all been studied for more than 8 years, revealing the research hotspots and trends of TCM in the treatment of influenza.
    CONCLUSIONS: The overall research related to the treatment of influenza with TCM is relatively perfect. In the future, the close cooperation among authors and institutions should be strengthened. The molecular mechanism research, clinical and animal trials of TCM should be further studied, so as to improve the research system of TCM treatment of influenza.

    Brazilian Publication Profiles: Where and How Brazilian authors publish.
    Concepta M McManus, Abilio A Baeta Neves, Andrea Q MaranhÃo.
      Publishing profiles can help institutions and financing agencies understand the different needs of knowledge areas and regions for development within a country. Incites ® (Web of Science) was used to see where Brazilian authors were publishing, the impact, and the cost of this publishing. The USA was the country of choice for publishing journals, along with Brazil, England, and the Netherlands. While Brazilian authors continue to publish in hybrid journals, they are more often opting for closed access, with 89% of the papers published in Brazil being open access, compared with 21% of papers published abroad. The correlation between the cost of publishing and the number of citations was positive and significant. Publishing patterns were different depending on the area of knowledge and the Brazilian region. Stagnation or reduction in publications with international collaboration, industry collaboration, or in high impact open access journals may be the cause of a reduction in citation impact. These data can help in elaborating public and institutional policies for financing publications in Brazil, especially when looking at unfavourable changes in currency exchange rates.

    Medical Degree Disparity Among Authors of Original Research in Pediatric Journals: A Four-Year Follow-Up.
    Michael Dabrowski, John Ashurst.
       INTRODUCTION AND OBJECTIVE: Scholarly activity is a major component of residency training and the accreditation process for graduate medical education. In 2014, Accreditation Council for Graduate Medical Education and the American Association of Colleges of Osteopathic Medicine announced a single accreditation system with the transition beginning July 1, 2015. Previous data before the transition had shown that osteopathic physicians rarely published original research in three high-impact pediatric journals. The objective of this study is to determine if there is a degree disparity between osteopathic and allopathic physicians among authors who publish original research manuscripts in three high-impact pediatric journals after the beginning of the transition to a single graduate medical education accreditation system.  Methods: Degree designation for the first and senior authors of original research manuscripts was reviewed for the Journal of Pediatrics (J Pediatr), Pediatrics, and JAMA Pediatrics (JAMA Pediatr) for the years 2016, 2017, 2018, and 2019. Inter-rater reliability was calculated by the kappa coefficient, and data were analyzed with descriptive statistics and simple linear regression.  Results: A total of 3,252 manuscripts and 4,068 authors were reviewed with 0.98% of all authors being osteopathic physicians. A total of 1.65% of first authors and 0.41% of senior authors were osteopathic physicians. For those with a dual degree, a total of 1.03% of first, and 0.41% of senior authors were osteopathic physicians. No statistical trend could be established for increased first, senior, dual-degree first, or dual-degree senior osteopathic physician authorship.
    CONCLUSION: Osteopathic physicians continue to be underrepresented as first and senior authors in original publications in the three high-impact pediatric journals as compared to their allopathic counterparts.

    A bibliometric analysis of 23,492 publications on rectal cancer by machine learning: basic medical research is needed.
    Kangtao Wang, Chenzhe Feng, Ming Li, Qian Pei, Yuqiang Li, Hong Zhu, Xiangping Song, Haiping Pei, Fengbo Tan.
       Background and Aims: The aim of this study was to analyse the landscape of publications on rectal cancer (RC) over the past 25 years by machine learning and semantic analysis.
    Methods: Publications indexed in PubMed under the Medical Subject Headings (MeSH) term 'Rectal Neoplasms' from 1994 to 2018 were downloaded in September 2019. R and Python were used to extract publication date, MeSH terms and abstract from the metadata of each publication for bibliometric assessment. Latent Dirichlet allocation was applied to analyse the text from the articles' abstracts to identify more specific research topics. Louvain algorithm was used to establish a topic network resulting in identifying the relationship between the topics.
    Results: A total of 23,492 papers published were identified and analysed in this study. The changes of research focus were analysed by the changing of MeSH terms. Studied contents extracted from the publications were divided into five areas, including surgical intervention, radiotherapy and chemotherapy intervention, clinical case management, epidemiology and cancer risk as well as prognosis studies.
    Conclusions: The number of publications indexed on RC has expanded rapidly over the past 25 years. Studies on RC have mainly focused on five areas. However, studies on basic research, postoperative quality of life and cost-effective research were relatively lacking. It is predicted that basic research, inflammation and some other research fields might become the potential hotspots in the future.

    Holistic Analysis of Coronavirus Literature: A Scientometric Study of the Global Publications Relevant to SARS-CoV-2 (COVID-19), MERS-CoV (MERS) and SARS-CoV (SARS).
    Engin Şenel, Fatih Esad Topal.
       OBJECTIVE: In late December 2019, a cluster of patients with pneumonia caused by an unknown pathogen was reported from Wuhan, Hubei Province, China. The pathogen has been identified as a novel coronavirus, SARS-CoV-2 and the disease has been named as COVID-19. The objective of this study to perform the first holistic scientometric evaluation of coronavirus publications.
    METHODS: Our main source for this study was Web of Science Collection database. All items published between 1980 and 2019 were included. A distribution map of global production in coronavirus literature and scientometric networks were generated.
    RESULTS: The USA, China, Germany the UK and Netherlands were the most productive countries. Publications in coronavirus literature have been produced from almost every country in the world, except for some countries in Asia and Africa.
    CONCLUSION: While in 1980s the USA and developed countries from Europe were major source countries and the virus was identified only as an animal disease in the literature and its biological and genetic structure was investigated, in the 2000s, China became a major contributor of coronavirus literature because the SARS outbreak originated from southern China. Almost all most cited publications in this period are related to SARS and ACE2 protein. In 2010s.

    The use of BEME reviews in the medical education literature.
    Tanya Horsley, Yvonne Steinert, Karen Leslie, Anna Oswald, Farah Friesen, Rachel H Ellaway.
       INTRODUCTION: Knowledge syntheses in medical education are intended to promote the translation to, and mobilization of, research knowledge into practice. Despite the effort invested in conducting them, how these knowledge syntheses are used is unclear. This study aimed to explore how knowledge syntheses published by the Best Evidence Medical Education Collaboration (BEME) have been used, in a cross-section of published literature.
    METHODS: Citation patterns for BEME reviews were explored using data drawn from Web of Science and Scopus, and a sub-sample of citing papers.
    RESULTS: Bibliometric data on 3419 papers citing 29 BEME reviews were analysed. More detailed data were extracted from a random sample of 629 full-text papers.
    DISCUSSION: BEME reviews were most often positioned to consolidate and summarize the current state of knowledge on a particular topic and to identify gaps in the literature; they were also used to justify current research, and less frequently used to contextualize and explain results, or direct future areas of research. Their use to identify instruments or methodological approaches was relatively absent.
    CONCLUSION: While BEME reviews are primarily used to justify and support other studies, the current literature does not demonstrate their translation to educational practice.

    Insights into stem cell therapy for diabetic retinopathy: a bibliometric and visual analysis.
    Xiang-Jun Li, Chun-Yan Li, Dan Bai, Ying Leng.
      Stem cells have been confirmed to be involved in the occurrence and development of diabetic retinopathy; however, the underlying mechanisms remain unclear. In this study, we used Citespace software to visually analyze 552 articles exploring the stem cell-based treatment of diabetic retinopathy over the past 20 years, which were included in the Web of Science Core Collection. We found the following: (1) a co-citation analysis of the references cited by all 552 articles indicated 15 clusters. In cluster #0, representing the stem cell field, some highly cited landmark studies emerged between 2009-2013. For example, endothelial progenitor cells and diabetic retinopathy gradually received the full attention of scholars, in terms of their relationship and therapeutic prospects. Some researchers also verified the potential of adipose-derived stem cells to differentiate into stable retinal perivascular cells, using a variety of animal models of retinal vascular disease. All of these achievements provided references for the subsequent stem cell research. (2) An analysis of popular keywords among the 552 articles revealed that, during the past 20 years, a relative increase in basic research articles examining stem cells and endothelial progenitor cells for the treatment of diabetic retinopathy was observed. The contents of these articles primarily involved the expression of vascular endothelial growth factor, vascular regeneration, oxidative stress, and inflammatory response. (3) A burst analysis of keywords used in the 552 articles indicated that genetic and cytological research regarding the promotion of angiogenesis was an issue of concern from 2001 to 2012, including several studies addressing the expression of various growth factor genes; from 2014 to 2020, mouse models of diabetic retinopathy were recognized as mature animal models, and the most recent research has focused on macular degeneration, macular edema, neurodegeneration, and inflammatory changes in diabetic animal models. (4) Globally, the current authoritative studies have focused on basic research towards the stem cell treatment of diabetic retinopathy. Existing clinical studies are of low quality and have insufficient evidence levels, and their findings have not yet been widely accepted in clinical practice. Major challenges during stem cell transplantation remain, including stem cell heterogeneity, cell delivery, and the effective homing of stem cells to damaged tissue. However, clinical trials examining potential stem cell-based treatments of diabetic retinopathy, including the use of pluripotent stem cells, retinal pigment epithelial cells, bone marrow mesenchymal stem cells, and endothelial progenitor cells, are currently ongoing, and high-quality clinical evidence is likely to appear in the future, to promote clinical transformation.

    Characteristics and Publication Rates for Podium Presentations at National Hand Surgery Meetings from 2007 to 2012.
    Alexander S Kuczmarski, Nicholas J Lemme, Dustin Biron, Andrew D Sobel, Arnold-Peter C Weiss.
      The purpose of this study was to evaluate and compare the research presented at the annual meetings of the American Society for Surgery of the Hand (ASSH) and the American Association for Hand Surgery (AAHS). Podium presentation data were extracted from the abstract books of the annual meetings of the ASSH and AAHS from 2007 to 2012. Corresponding publications were identified using searchable online publication databases and an algorithm linking authorship and content. The majority of research was clinical and the most common topics were trauma, degenerative conditions, and biomechanics. The most common body region of interest was the wrist/forearm. ASSH podium presentations were of a stronger level of evidence and were more likely to be published. The mean times to publication for research presented at the ASSH and AAHS meetings were 16.7 and 16.4 months, respectively. Presentations from each society were subsequently published at higher proportions in their affiliated journals. Furthermore, in comparison to AAHS presentations, a significantly larger proportion of research presented at the ASSH meetings was published in the Journal of Bone and Joint Surgery , while a larger proportion of AAHS presentations were published in Plastic and Reconstructive Surgery and Microsurgery .

    A 30-year analysis of National Institutes of Health-funded cardiac transplantation research: Surgeons lead the way.
    Adishesh K Narahari, J Hunter Mehaffey, Anirudha S Chandrabhatla, Pranav K Baderdinni, Allison Weiderhold, Ian O Cook, Robert B Hawkins, Mark E Roeser, John A Kern, Irving L Kron, Leora T Yarboro, Gorav Ailawadi, Nicholas R Teman.
       OBJECTIVES: Obtaining National Institutes of Health funding for heart transplant research is becoming increasingly difficult, especially for surgeons. We sought to determine the impact of National Institutes of Health-funded cardiac transplantation research over the past 30 years.
    METHODS: National Institutes of Health Research Portfolio Online Reporting Tools Expenditures and Results was queried for R01s using 10 heart transplant-related terms. Principal Investigator, total grant funding amount, number of publications, and citations of manuscripts were collected. A citation-based Grant Impact Metric was assigned to each grant: sum of citations for each manuscript normalized by the funding of the respective grant (per $100K). The department and background degree(s) (MD, PhD, MD/PhD) for each funded Principal Investigator were identified from institutional faculty profiles.
    RESULTS: A total of 321 cardiac transplantation R01s totaling $723 million and resulting in 6513 publications were analyzed. Surgery departments received more grants and more funding dollars to study cardiac transplantation than any other department (n = 115, $249 million; Medicine: n = 93, $208 million; Pathology: 26, $55 million). Surgeons performed equally well compared with all other Principal Investigators with respect to Grant Impact Metric (15.1 vs 20.6; P = .19) and publications per $1 million (7.5 vs 6.8; P = .75). Finally, all physician-scientists (MDs) have a significantly higher Grant Impact Metric compared with nonclinician researchers (non-MDs) (22.3 vs 16.3; P = .028).
    CONCLUSIONS: Surgeon-scientists are equally productive and impactful compared with nonsurgeons despite decreasing funding rates at the National Institutes of Health and greater pressure from administrators to increase clinical productivity.

    Visualizing Research on Industrial Clusters and Global Value Chains: A Bibliometric Analysis.
    Thais González-Torres, José-Luis Rodríguez-Sánchez, Antonio Montero-Navarro, Rocío Gallego-Losada.
      In the current digital era, the borders amongst firms are getting blurred when it comes to value creation. Therefore, the traditional configuration of the value chain is frequently replaced by other ones which include the collaborative participation of different agents. Within this context, global value chains, where the value activities are located in different countries, and industrial clusters, which combine competition and cooperation, are attracting a growing attention of both business leaders and scholars in the recent years. Through a bibliometric analysis, this paper disentangles the intellectual and conceptual structure of the research topic of industrial clusters and global value chains. Results show the multidisciplinary character of the topic, including papers published in different areas, such as business, regional studies and world development, as well as its close link with aspects like innovation, regional development, governance or organization. Finally, this study remarks the research lines that could attract more attention in the immediate future.

    What is there in the scoring and rating of journals?
    Raju Vaishya, Abhishek Vaish, Abid Haleem.
      Medical and associated speciality journals aim to disseminate area-specific knowledge, discoveries, experiences, cases and substantiate or negate the previously published pieces of information. These Journals are considered essential for doctors, researchers, and scientists to disseminate work, research, and experiences with the rest of the world. However, it is often quite challenging to choose an appropriate journal to submit work for possible publication. Researchers attempt to choose the most appropriate platform to highlight their research work so that their work gets published in good order, read, and referred. Hence, selecting an appropriate journal is the most vital task for them. Although no ranking and scoring system can be 100% perfect and foolproof, yet the scoring systems are required to be fair and objective in scoring the journals on various metrics and parameters.

    Manuscript Referencing Errors and Their Impact on Shaping Current Evidence.
    Anastasia Rivkin.
      It is imperative that articles published in reputable peer-reviewed journals provide balanced, fair, objective, and accurate references. However, studies on the accuracy of references in various scientific disciplines demonstrate an error rate of 25%-54%. These errors can range from minor errors in citation accuracy to major errors that alter the original content and meaning of the material referenced. This article discusses importance of citation accuracy, reviews principles of good citation practices, and offers recommendations aimed to decrease citation error rates.

    The Bibliometric Analysis of the Studies Presented at the Turkish National Otorhinolaryngology Congresses in the Period 2009-2018.
    Mehmet İlhan Şahin, Emrah Gülmez, Nazlım Hilal Taraf, Veli Çetinaslan, Alperen Vural, Yaşar Ünlü, Özgür Yiğit.
       Objective: The aim of this study was to quantitatively and qualitatively analyze the abstracts presented at Turkish National Otorhinolaryngology Congresses in the years from 2009 to 2018.
    Methods: Abstracts were defined and grouped according to their field of study, design, level of evidence, number of authors, the main institution in which they were held, and whether they were uni- or multi-centric. Frequency and percentage tables were prepared.
    Results: In total, 5,463 studies, of which 1,431 (26.2%) were oral presentations and 4,032 (73.8%) were poster presentations were reviewed. The highest number of studies was in the field of otology and in the form of oral presentations (32%), and in the field of head and neck surgery in the form of poster presentations (37%). Fifty-seven percent of all studies were conducted in university hospitals, and 34% in Training and Research Hospitals. Eighty-three percent of oral presentations and 99% of poster presentations were clinical studies. The rate of experimental animal studies was 16% in oral presentations. The most commonly used design of orally presented clinical studies was descriptive (31%), whereas prospective randomized controlled design was the least common (3%). No study with a level 1 of evidence was found. The rate of oral papers presented with evidence levels 2, 3, 4, and 5 among all oral presentations were 22%, 13%, 11%, and 54%, respectively.
    Conclusion: The findings indicated that the abstracts were satisfactory in quantity, but overall scientific quality was not sufficient. The data obtained may serve as a basis for future studies, and follow-up studies may guide individuals and institutions that steer the Turkish ENT community.

    Social, Behavioral, and Cultural factors of HIV in Malawi: Semi-Automated Systematic Review.
    Amaury Thiabaud, Isotta Triulzi, Erol Orel, Kali Tal, Olivia Keiser.
       BACKGROUND: Demographic and sociobehavioral factors are strong drivers of HIV infection rates in sub-Saharan Africa. These factors are often studied in qualitative research but ignored in quantitative analyses. However, they provide in-depth insight into the local behavior and may help to improve HIV prevention.
    OBJECTIVE: To obtain a comprehensive overview of the sociobehavioral factors influencing HIV prevalence and incidence in Malawi, we systematically reviewed the literature using a newly programmed tool for automatizing part of the systematic review process.
    METHODS: Due to the choice of broad search terms ("HIV AND Malawi"), our preliminary search revealed many thousands of articles. We, therefore, developed a Python tool to automatically extract, process, and categorize open-access articles published from January 1, 1987 to October 1, 2019 in the PubMed, PubMed Central, JSTOR, Paperity, and arXiV databases. We then used a topic modelling algorithm to classify and identify publications of interest.
    RESULTS: Our tool extracted 22,709 unique articles; 16,942 could be further processed. After topic modelling, 519 of these were clustered into relevant topics, of which 20 were kept after manual screening. We retrieved 7 more publications after examining the references so that 27 publications were finally included in the review. Reducing the 16,942 articles to 519 potentially relevant articles using the software took 5 days. Several factors contributing to the risk of HIV infection were identified, including religion, gender and relationship dynamics, beliefs, and sociobehavioral attitudes.
    CONCLUSIONS: Our software does not replace traditional systematic reviews, but it returns useful results to broad queries of open-access literature in under a week, without a priori knowledge. This produces a "seed dataset" of relevance that could be further developed. It identified known factors and factors that may be specific to Malawi. In the future, we aim to expand the tool by adding more social science databases and applying it to other sub-Saharan African countries.

    Global Emergency Medicine: A Review of the Literature from 2019.
    Global Emergency Medicine Literature Review (GEMLR) Group
       OBJECTIVE: The annual systematic search of the peer-reviewed and gray literature relevant to global emergency medicine (EM) was conducted by the Global Emergency Medicine Literature Review (GEMLR) to screen, evaluate, and review the most rigorously conducted and relevant research in global EM published in 2019.
    METHODS: After a broad search of PubMed and websites of organizations publishing relevant gray literature, all articles that were deemed relevant to the fields of Disaster and Humanitarian Response, Emergency Care in Resource-Limited Settings, and Emergency Medicine Development by at least one reviewer, an editor, and the managing editors were then scored by two different reviewers using a 20-point scoring template relevant to either original research (OR) or review (RE) articles. This scoring system rates articles on their clarity, research design, ethics, importance to global EM, and breadth of impact. Articles which then scored in the top 5% were then critiqued in depth.
    RESULTS: A total of 23,321 article titles and abstracts were screened by 22 reviewers with a wide swath of clinical and research experience in global EM. From these, a total of 356 articles underwent full-text review and scoring on the 20-point scale; 26% were categorized as Disaster and Humanitarian Response, 58% as Emergency Care in Resource-Limited Settings, and 15% as Emergency Medicine Development. Of these 356 articles, 276 (77.5%) were original research articles and 80 (22.5%) were review articles. The sixteen articles which scored in the top 5% (>17.5 out of 20 points) received full in-depth narrative summaries.
    CONCLUSIONS: In 2019, the overall number of studies relevant to global EM that were identified by our search decreased from the prior year, but more high-scoring articles related to the development of EM clinical practice and as a specialty in resource-constrained settings were identified.

    Gender differences in urology society award recipients.
    Netsanet Woldegerima, Alexander Thomopulos, Andrea Bafford, Rena D Malik.
       BACKGROUND: Approximately 91% of urologists are male and 9% female. We aim to characterize gender differences amongst urology society awardees over the past six decades.
    METHODS: We queried 16 American urology societies. Inclusion criteria were active membership enrollment, majority urologist members, and awards provided at an annual, biennial or triennial basis.
    RESULTS: Ten urology societies were included. Between 1963 and 2019, 848 awardees for 34 awards were identified. Men comprised 92.2% and women 7.8% of recipients. The highest percentage of women awardees per year (21.7%) occurred in 2018, increased from 6.5% in 2008 and 0% in 1998. Over the last 11 years, women received 0% of awards offered 61% of the time.
    CONCLUSIONS: There is an increased trend in the representation of women awardees by urology societies, although the frequency varies widely between societies. This is in keeping with the trend of increasing number of women entering the field of urology.
