    Treatment of anterior shoulder instability: a bibliometric analysis.
    Mingtao Zhang, Zhitao Yang, Borong Zhang, Tao Liu, Xiangdong Yun.
      PURPOSE: The treatment of anterior shoulder instability is a focus in the field of sports medicine. While much research has been conducted, few bibliometric studies have been performed in this field. This study analyzed the main characteristics and identified emerging research trends and hotspots related to the treatment of anterior shoulder instability over the past four decades.METHODS: We searched for (anterior shoulder instability OR anterior shoulder dislocation) AND (treatment OR reconstruction) in ARTICLE (Mesh) in the Web of Science database from 1980 to 2020. We analyzed the keywords, author, institution, country, number of citations, average number of citations, publication year, and partnership of the identified articles. Information about annual publications was analyzed using Microsoft Excel 2019; the remaining data were analyzed using VOSviewer version 1.6.11 (Leiden University, Leiden, Netherlands) and CiteSpace version 5.7.R2 (Drexel University, Philadelphia, PA, USA).
    RESULTS: A total of 1964 articles were published between 1980 and 2020. The American Journal of Sports Medicine, the United States, the United States Department of Defense, and Arcieio were journals, countries, institutions, and authors with the highest numbers of publications. The topic hotspots were instability, shoulder, and dislocation, while the research frontiers were arthroscopic, Bankart repair, Latarjet procedure, risk factors, recurrence, and complications.
    CONCLUSION: The treatment of anterior shoulder instability has shown an increasing number of publications each year and achieved great progress. The United States made the most outstanding contributions to this important field. Arthroscopic, Bankart repair, and Latarjet procedures were research hotspots and risk factors, recurrence, and complications were likely to research frontiers.

    Mohammed Madadin, Nadeem Siddique, Abu Waris, Muhammad Ajmal Khan, Hassan S Albarbari, Alok Atreya, Imran Sabri, Sara F Owaidah, Ritesh G Menezes.
      This paper aims to examine the worldwide research development and trends in forensic anthropology by using bibliometric analysis. Scopus database was used to identify published papers on forensic anthropology from 1948 to 2020. A total of 4,499 records were analyzed for yearly publication productivity, authorship and citation pattern, types of documents, most productive journals, organizations, authors, and countries, frequently cited papers, most used keywords, countries of collaboration, and three-field plot analysis in the domain of forensic anthropology. The results indicated that the highest grand total publications were between the years 2016 and 2019, while the highest multi-authored publications were in the year 2018. The most productive journal, author, organization, and country were the 'Journal of Forensic Sciences' with grand total publications of 934, 'Cattaneo, C.' with 97 publications, 'Centre National de la Recherche Scientifique' with 130 publications, and the United States with 1020 total cited papers, respectively. The document with the highest number of citations was 'Buckberry and Chamberlain, 2002, Am J Phys Anthropol' with a total of 387. Three-field plot analysis regarding the most outstanding keyword-source-country was "Forensic anthropology"- "Journal of Forensic Sciences" and "Forensic Science International"- "USA", "France", and "UK". The predomination of certain countries over others in the field of forensic anthropology limits its prosperity as ethnic variety is of important regard. Research collaborations were mainly observed between the United States and European countries, which highlights the need for strengthening collaborations between developed and developing nations.

    The 100 most influential articles in myopia: a bibliometric analysis.
    Xue-Jiao Wang, Di Chen, Yang Jiang, Yu-Yu Chou, Yan Luo, Ying Li, Jin Ma, Yong Zhong.
      AIM: To identify and characterize the 100 most influential articles in the field of myopia over the last decades.METHODS: Articles on myopia published between January 1975 and March 2020 were searched through the Web of Science Core Collection database. Two independent authors reviewed and determined the 100 most cited articles. The characteristics of each eligible article were recorded, including authors, institutions, countries, journals, publication date, total citations (TCs), annual citations (ACs), research focus and article type.
    RESULTS: The top 100 most influential articles were published between 1983 and 2016, with 1999 as the most prolific year. The mean number of TCs was 288 (range: 193-537) and the mean number of ACs was 19 (range: 7-109). Treatment and epidemiology of myopia were the most important research focus. These articles were published in 21 journals led by Ophthalmology (29%) followed by Investigative Ophthalmology & Visual Science (23%). The number of ACs for articles published in the last ten years was significantly higher than that for the other most-cited articles (44 vs 16, Mann-Whitney U test P<0.01). There is no difference in the number of TCs between original articles and review articles, while the number of ACs for review articles was significantly higher than that for original articles (22 vs 17, Mann-Whitney U test P<0.05).
    CONCLUSION: This bibliometric analysis can provide us with concise information about the development trend of research in the field of myopia in the past few decades, and provide an important reference for researchers to guide future research.

    Yi Qin, Sifan Chen, Yuanyuan Zhang, Wanfeng Liu, Yuxuan Lin, Xiaoying Chi, Xuemei Chen, Zhangjie Yu, Diansan Su.
      Background and Aims: To evaluate endoscopic sedation research and predict research hot spots both quantitatively and qualitatively using bibliometric analysis. Methods: We extracted relevant publications from the Web of Science Core Collection (WoSCC) on 13 December 2020. We examined the retrieved data by bibliometric analysis (e.g., co-cited and cluster analysis, keyword co-occurrence) using the software CiteSpace and VOSviewer and the website of bibliometrics, the Online Analysis Platform of Literature Metrology (http://bibliometric.com/), to analyse and predict the trends and hot spots in this field. Main Results: We identified 2,879 articles and reviews on endoscopic sedation published between 2001 and 2020. Although the overall trend is increasing, with slight fluctuation in some years, there were significant increases in 2007 and 2012. In respect of the contributions on endoscopic sedation research, the United States (US) had the greatest number of publications, and it was followed by Japan and China. In addition, collaboration network analysis revealed that the most frequent collaboration was between the US and China. Six of the top ten most prolific research institutions were located in the US. The most publications on endoscopic sedation research in the past two decades were found primarily in journals on gastroenterology and hepatology. Keyword co-occurrence and co-citation cluster analysis revealed the most popular terms relating to endoscopic sedation in the manner of cluster labels; these included patient anxiety, tolerance, ketamine, propofol, hypoxia, nursing shortage, endoscopic ultrasonography, colorectal cancer, carbon dioxide insufflation, and water exchange (WE). Keyword burst detection suggested that propofol sedation, adverse event, adenoma detection rate (ADR), hypoxemia, and obesity were newly-emergent research hot spots. Conclusions: Our findings showed that hypoxia, adverse event, and ADR, along with conscious sedation and propofol sedation, have been foci of endoscopic sedation research over the past 20 years. The research focus has shifted from sedative drugs to sedative complications and endoscopy quality control, which means that there will be higher requirements and standards for sedative quality and endoscopy quality in the future.

    Beomjun Seo, Seungwook Kim, Jeeyoon Kim.
      Background: Bibliometric analyses are used to provide information on trends within a specific research field, along with indicators of the impact of a publication. With such an analysis, we map the scientific landscape of chimeric antigen receptor T-cell (CAR-T) research to see the emerging topics and infer directions the field might take. Methods: We extracted the 100 most-cited articles, published all periods (from 2008 to 2019) by the Web of Science Core Collection. Using their bibliographic details, including year of publication, country of author, research organization, author information, and keywords, we graph the networks created between the articles. Results: Of the 100 papers identified, the majority (93%) were written in the USA. Notable was that 34 papers were published from the University of Pennsylvania. Regarding authors, Carl H. June participated in 29 researches, followed by Bruce L. Levine who participated in 12. As for journals, Blood (n = 19) published the most papers, followed by Science Translational Medicine (n = 9) and Cancer Research (n = 9). Lastly, the most frequently used keywords were "adoptive immunotherapy" (n = 47), "lymphocytes" (n = 27), and "antitumor activity" (n = 22). Conclusion: By evaluating the top 100 most-cited papers in the CAR-T field, this study provides insight into the direction of the scientific growth and its trends, as well as information on the field's network structure.

      BACKGROUND AND AIM: Globally, congenital cataract remains one of the main causes of visual loss in children. This study was designed to plot the overall research output and evaluate some key bibliometric indicators in congenital cataracts research.METHODS: Publications on congenital cataracts were retrieved from the Web of Science Core Collection database. The published literature was searched using the keywords "congenital cataract" OR "congenital cataracts" in the title filed with document types and language restrictions. The data were exported into HistCite to analyze; publication year, top authors, countries, institutions, journals, keywords, and most cited studies. VOSviewer software was used to construct network visualization mapping.
    RESULTS: A total of 1427 publications (1903-2021) published in English language were included in this study. Over the past few decades, the total number of publications in congenital cataracts was found to be increased. The most productive year was 2016 (n = 72), while the most cited year was 1941 (1268 citations). The Investigative Ophthalmology & Visual Science (Impact Factor: 4.799) was the most attractive journal with 161 publications, and the Molecular Vision (Impact Factor : 2.367) was the most cited journal with 1915 citations and 161.723 citations per year. The most productive country was the United States of America (USA) (n = 325), while the most active institute was Sun Yat-sen University, China (n = 36). The most prolific author was Yao K (n = 27). The most studied Web of Science category was ophthalmology (n = 852). The most widely used keyword was congenital (n = 1427). The most cited paper in congenital cataracts was "Congenital cataract following German measles in the mother, cited 1268 times. The USA and author keyword congenital cataract had the highest total link strength.
    CONCLUSION: These findings provide useful insights, current status, and trends in clinical research in congenital cataracts. This study can be used to identify future research areas and standard bibliography references for better diagnosis and disease control.

    The comparative landscape of Chinese and foreign articles on the carbon footprint using bibliometric analysis.
    Rong Wu, Yundong Xie, Yezhu Wang, Zhi Li, Li Hou.
      In recent years, the carbon footprint is regarded as the most important assessment tool of greenhouse gas emissions; it has attracted great attention of Chinese and foreign governments, enterprises, and relevant scholars. However, the comparative bibliometric analysis of Chinese and foreign articles on the carbon footprint research is still limited; thus, it has become the motivation of the present study. To quantitatively analyse the bibliometric differences between Chinese and foreign literature of the carbon footprint research, 673 Chinese articles and 3755 foreign articles between 2007 and 2020 were extracted from the Web of Science Core Collection database. On this basis, the publications, publishers, journals, authors, and institutions of Chinese and foreign articles were compared, and especially, the keyword and citation analysis results were obtained via the biblioshiny tool of bibliometrix R package. Results show that the output and influence of foreign articles are more prominent than Chinese articles in general. The foreign carbon footprint research is more systematic and mature than Chinese research, and both sides have some research topics of common concern and maintain their own research characteristics. Specific results may provide some reference for relevant researchers, policy makers, and the public.

    ALTMETRIC ANALYSIS OF THE MOST-CITED 100 ARTICLES ON THE RETINA PUBLISHED BETWEEN 2010 AND 2020.
    Hidayet Sener, Osman Ahmet Polat.
      PURPOSE: Altmetric analysis is a way of assessing the social impact of scientific articles. In this study, we aimed to analyze the 100 most-cited articles on the topic of the retina published in ophthalmology journals in traditional metrics and altmetrics.METHODS: The term "retina" was searched in the Web of Science database, and articles published in ophthalmology journals were filtered out. A total of 100 highly cited articles from 2010 to 2020 were evaluated for bibliographic data and altmetrics. First, descriptive statistics and then correlation analysis between traditional bibliographies and altmetrics were performed.
    RESULTS: According to the Web of Science search, the number of citations of the articles listed in the top 100 list ranged from 809 to 137. The altmetric scores of the articles listed in the top 100 list ranged from 0 to 1,340. There was no statistically significant correlation between the altmetric scores and the number of citations, but there was a statistically weak correlation between the altmetric scores and the average citations per year, H index, impact factor, and number of years since publication.
    CONCLUSION: Altmetrics is not sufficient to determine the scientific value of articles and can be affected by many factors, unlike traditional bibliometrics. However, being a good communicator in social media can support scientific productivity and create social impact.

    The most influential articles on kidney transplantation: A PRISMA-compliant bibliometric and visualized analysis.
    Heungman Jun, Ji Woong Hwang.
      BACKGROUND: Kidney transplantation (KT) has become common in the treatment of end-stage renal disease. However, to date, there have been no bibliometric analyses of KT research to identify the most influential articles. The purpose of this research is to identify and characterize the 100 most cited articles that focus on KT and to clarify the trends in the accomplishments in this field.METHODS: We searched the Thomson Reuters Web of Science citation indexing database and used keyword mapping of VOSviewer. The top 100 most cited manuscripts were analyzed based on their titles, authors, institutions, countries of origin, years of publication, and topics.
    RESULTS: The New England Journal of Medicine has published the most manuscripts on kidney transplantation (n = 26) and is the most cited journal (n = 15,642). The United States has the highest number of publications (n = 61). Kashika is the corresponding author with the most published papers (n = 5; 2892 citations). The most common topics of publication are immunosuppressant (n = 34), clinical outcome (n = 26), and pathology (n = 22). Keywords related to immunosuppressant are the most common in keyword mapping with VOSviewer.
    CONCLUSIONS: This bibliometric analysis of KT research provides the research characteristics and publication trends of this topic. In KT research, immunosuppressants and post-transplant clinical outcomes have been important topics.

    Marco Franceschini, Angelo Boffa, Luca Andriolo, Alessandro Di Martino, Stefano Zaffagnini, Giuseppe Filardo.
      PURPOSE: Articular cartilage lesions remain a challenge for orthopedic surgeons. The identification of the most important articles can help identifying the most influential techniques of the past, the current prevalent focus, and emerging strategies. The aim of this study was to identify milestones and trends in cartilage research.METHODS: This study is a bibliometric analysis based on published articles. All citation count data included in the "Scopus database" were used to identify eligible studies up to December 2020. The 50 most-cited articles on cartilage surgery were ranked based on the citation count and analyzed regarding citation density and quality (Coleman score and RoB 2.0 tool). A further search was performed to identify the most promising clinical studies among the latest publications on cartilage surgery.
    RESULTS: Different kinds of cartilage treatments were investigated in the 50 most-cited clinical articles. Regenerative techniques with chondrocytes were the most reported with a total of 23 articles, followed by microfracture technique in 17 articles and mosaicplasty or osteochondral autograft transplantation (OAT) in 11. Forty-five articles focused on the knee. A higher citation density was found in the most recent articles (p = 0.004). The study of the most promising landmarks of the most recent articles showed new cell-free or tissue engineering-based procedures and an overall increasing quality of the published studies.
    CONCLUSION: This bibliometric analysis documented an increasing interest in cartilage surgery, with efforts toward high-quality studies. Over the years, the focus switched from reconstructive toward regenerative techniques, with emerging options including cell-free and tissue-engineering strategies to restore the cartilage surface.

    Evidence and consequences of academic drift in the field of dental research: A bibliometric analysis 2000-2015.
    Puck van der Wouden, Geert van der Heijden, Hagay Shemesh, Peter van den Besselaar.
      The mission of academic excellence has resulted in a science system that incentivises publications within high impact, often basic science journals, and less in application-oriented journals. For the dental research field this so-called academic drift can result in a research portfolio that moves away from research that serves dental healthcare. Therefore, we examined if and how academic drift has changed the dental research field. Web of Science data were used to develop a network map for dental research containing journal clusters that show similar citation behavior. From the year 2000 up to 2015, we explored the intensity of knowledge exchange between the different clusters through citation relations. Next, we analyzed changes in research focus of dental research institutes in seven countries, in dental research, clinical medicine research, basic science, public health research and other fields. Within the citation network, 85.5% of all references in dental journals concern references to other dental journals. The knowledge contribution of non-dental research fields to dental research was limited during the studied period. At the same time, the share of output of dental research institutes in dental research has declined. The research activity of the dental research institutes increased mainly in basic science while the knowledge input from basic science into dental research did not increase. Our findings suggest that the dental research portfolio is influenced by academic drift. This academic drift has increased the disbalance towards basic science, and presents a challenge for the scientific progress in dental healthcare services.

    Laura Carrasco Cortijo, Jose A Quesada, Adriana Lopez-Pineda, Domingo Orozco-Beltrán, Vicente F Gil-Guillen, Concepcion Carratala-Munuera.
      Background: To identify the strengths and weaknesses in a given research area, it is necessary to analyze the published literature. International studies on podiatry research productivity are scarce. This study aimed to analyze scientific productivity in the area of podiatric medicine from 1965 to 2017.Methods: This was a retrospective, observational, bibliometric study. The MEDLINE database was used to identify research published between 1965 and 2017. Literature searches were performed in 2010 and 2017 through RefWorks, and research production per year, author, document type, country, institution, journal, and language were calculated. Podiatry's contribution to global scientific production was measured by calculating the ratio of podiatry publications to total production, and Price's law was applied to analyze the temporal evolution. Author productivity index, coauthorship, geographic distribution, and the distribution by institution type and journal (Bradford's law) were analyzed.
    Results: The MEDLINE search yielded 1,256 publications, representing 4.75 articles per 100,000 publications in global scientific research. The growth rate followed Price's law after linear adjustment. The 2,229 identified authors presented a transience index of 85.73%; 0.38% were highly productive authors. The coauthorship index increased from 1.40 in 1965 to 5.80 in 2017. The most common document type was the journal article, whereas 2.1% were clinical trials. Only one document reported a controlled clinical trial. The United States led scientific production, with 77.15% of the documents; 60.5% of the publications were concentrated in four journals.
    Conclusions: Podiatry is still an emerging research field, and literature is concentrated in a small number of journals, categorized into different subjects.

    Mapping Intellectual Structures and Research Hotspots of Triple Negative Breast Cancer: A Bibliometric Analysis.
    Kai-Jun Hao, Xiao Jia, Wen-Ting Dai, Ze-Min Huo, Hua-Qiang Zhang, Jing-Wei Liu, Xiao-Bing Wang.
      Background: Triple negative breast cancer (TNBC) is a highly heterogeneous breast cancer subtype with a poor prognosis due to its extremely aggressive nature and lack of effective treatment options. This study aims to summarize the current hotspots of TNBC research and evaluate the TNBC research trends, both qualitatively and quantitatively.Methods: Scientific publications of TNBC-related studies from January 1, 2010 to October 17, 2020 were obtained from the Web of Science database. The BICOMB software was used to obtain the high-frequency keywords layout. The gCLUTO was used to produce a biclustering analysis on the binary matrix of word-paper. The co-occurrence and collaboration analysis between authors, countries, institutions, and keywords were performed by VOSviewer software. Keyword burst detection was performed by CiteSpace.
    Results: A total of 12,429 articles related to TNBC were identified. During 2010-2020, the most productive country/region and institution in TNBC field was the USA and The University of Texas MD Anderson Cancer Center, respectively. Cancer Research, Journal of Clinical Oncology, and Annals of Oncology were the first three periodicals with maximum publications in TNBC research. Eight research hotspots of TNBC were identified by co-word analysis. In the core hotspots, research on neoadjuvant chemotherapy, paclitaxel therapy, and molecular typing of TNBC is relatively mature. Research on immunotherapy and PARP inhibitor for TNBC is not yet mature but is the current focus of this field. Burst detection of keywords showed that studies on TNBC proteins and receptors, immunotherapy, target, and tumor cell migration showed bursts in recent three years.
    Conclusion: The current study revealed that TNBC studies are growing. Attention should be paid to the latest hotspots, such as immunotherapy, PARP inhibitors, target, and TNBC proteins and receptors.

    Demeng Xia, Jianghong Wu, Feng Zhou, Sheng Wang, Zhentao Zhang, Panyu Zhou, Shuogui Xu.
      Background: Defects of articular cartilage represent a common condition that usually progresses to osteoarthritis with pain and dysfunction of the joint. Current treatment strategies have yielded limited success in these patients. Stem cells are emerging as a promising option for cartilage regeneration. We aim to summarize the developmental history of stem cells for cartilage regeneration and to analyse the relevant trends and hotspots. Methods: We screened all relevant literature on stem cells for cartilage regeneration from Web of Science during 2010-2020 and analysed the research trends in this field by VOSviewer and CiteSpace. We also summarized previous clinical trials. Results: We screened 1,011 publications. China contributed the largest number of publications (317, 31.36%) and citations (81,376, 48.61%). The United States achieved the highest H-index (39). Shanghai Jiao Tong University had the largest number of publications (34) among all full-time institutions. The Journal of Biomaterials and Stem Cell Research and Therapy published the largest number of studies on stem cells for cartilage regeneration (35). SEKIYA I and YANG F published the majority of articles in this field (14), while TOH WS was cited most frequently (740). Regarding clinical research on stem cells for cartilage regeneration, the keyword "double-blind" emerged in recent years, with an average year of 2018.75. In tissue engineering, the keyword "3D printing" appeared latest, with an average year of 2019.625. In biological studies, the key word "extracellular vesicles" appeared latest, with an average year of 2018.9091. The current research trend indicates that basic research is gradually transforming to tissue engineering. Clinical trials have confirmed the safety and feasibility of stem cells for cartilage regeneration. Conclusion: Multiple scientific methods were employed to reveal productivity, collaborations, and research hotspots related to the use of stem cells for cartilage regeneration. 3D printing, extracellular vesicles, and double-blind clinical trials are research hotspots and are likely to be promising in the near future. Further studies are needed for to improve our understanding of this field, and clinical trials with larger sample sizes and longer follow-up periods are needed for clinical transformation.

      OBJECTIVE: This bibliometric review of literature on posterior ligamentous complex (PLC) injury in thoracolumbar (TL) trauma aims to guide future research.METHODS: We conducted a keyword-based search from January 2000 to September 2021 using the Scopus database. Relevant publications were analyzed for the year of publication, authorship, publishing journals, institution and country of origin, subject matter, and article type. In addition, content analysis of clinical articles was performed, analyzing for sample size, study design (retrospective vs. prospective), single vs. multicenter, and level of evidence.
    RESULTS: 262 publications have been published in 61 journals by 537 authors, 162 institutions, and 29 countries. Thomas Jefferson University, the University of Calgary, and the University of Toronto have the largest number of publications related to PLC injury. The United States, Canada, and China were the most frequent contributors in terms of the number of publications. Spine was the most prolific and top-cited Journal, while Vaccaro A.R. was the most prolific author. The most cited publication was the Thoracolumbar Injury Classification and Severity Score (TLICS) classification by Vaccaro et al. in 2005. Most of the publications have been case studies, with diagnostic accuracy being the most frequently discussed topic. The sample size for a large portion of the case series was less than 50. The majority of case series were retrospective studies conducted at a single center.
    CONCLUSION: Our review provides an extensive list of the most historically significant spinal imaging articles, acknowledging the key contributions made to the advancement of this research area.

      Patients with microsatellite-instability-high (MSI-H) or mismatched repair-deficient colorectal cancer (CRC) appear to be responsive to checkpoint inhibitors. This study aimed to assess research trends in CRC immunotherapy. Publication patterns of articles covering immunotherapies in CRC in the Web of Science Core Collection database were retrospectively examined using VOS viewer software (version 1.6.16) prior to 25 May 2021. Ultimately, 3977 records were identified that were published between 1975 and 2021, which received a total of 128,681 citations (an average of 32.36 citations per item), with a noticeable rise in 2014. The majority of articles were published in the US (35.8%), China (17.7%), and Germany (9.4%). Publications mainly originated from the Institut National de la Santé Et De La Recherche Medicale Inserm, followed by the University of Texas System and Harvard University; however, Johns Hopkins University received the most citations (18,666 for 69 publications). The Journal of Clinical Oncology issued the most publications (n = 146), while the most referenced item (7724 citations) was published in the New England Journal of Medicine in 2012. The most common keywords were associated with tumors (expression and microsatellite instability) or immune system components (t-cells/dendritic cells). The findings demonstrate the scientific community's interest in the MSI-H subtype of colorectal tumors and how immunotherapy may be employed more successfully to treat metastatic CRC.

    Jinbo He, Jingshi Kang, Shaojing Sun, Marita Cooper, Hana F Zickgraf, Yujia Zhai.
      OBJECTIVE: Employing bibliometric methods, the present study aimed to map out the general landscape of existing research on eating disorders (EDs) over the past decades.METHOD: Using the Web of Science database, we retrieved 41,917 research articles related to EDs published from 1981 to 2020. After removing those without an abstract, a total of 37,446 articles were retained. The study outlined the distribution of scholarship by time, languages, regions, and countries, and identified major research lines by applying latent topic modelling.
    RESULTS: Results revealed a general increasing trend in the number of publications on EDs research, and researchers from Western countries dominated the production of related scholarship. The distribution of published scholarship varied significantly by languages, regions, and countries. Seven main research topics emerged from past research (i.e., animal studies of food intake, risk factors and at-risk groups for eating disorders, body image in eating disorders, studies of cognition and brain in eating disorders, symptomatology and comorbidity of eating disorders, body weight and nutrition status in eating disorders, and treatment of eating disorders), with different topics showing unique research trends across the years.
    CONCLUSIONS: This bibliometric analysis presents the most complete up-to-date overview on published research on EDs. While there is an increasing trend for EDs research, the available research evidence is generally from Western countries; thus, it is suggested that cooperation on EDs research should be strengthened between Western countries and other countries in the future.

    Siti Shaliza Mohd Khairi, Mohd Aftar Abu Bakar, Mohd Almie Alias, Sakhinah Abu Bakar, Choong-Yeun Liong, Nurwahyuna Rosli, Mohsen Farid.
      Medical imaging is gaining significant attention in healthcare, including breast cancer. Breast cancer is the most common cancer-related death among women worldwide. Currently, histopathology image analysis is the clinical gold standard in cancer diagnosis. However, the manual process of microscopic examination involves laborious work and can be misleading due to human error. Therefore, this study explored the research status and development trends of deep learning on breast cancer image classification using bibliometric analysis. Relevant works of literature were obtained from the Scopus database between 2014 and 2021. The VOSviewer and Bibliometrix tools were used for analysis through various visualization forms. This study is concerned with the annual publication trends, co-authorship networks among countries, authors, and scientific journals. The co-occurrence network of the authors' keywords was analyzed for potential future directions of the field. Authors started to contribute to publications in 2016, and the research domain has maintained its growth rate since. The United States and China have strong research collaboration strengths. Only a few studies use bibliometric analysis in this research area. This study provides a recent review on this fast-growing field to highlight status and trends using scientific visualization. It is hoped that the findings will assist researchers in identifying and exploring the potential emerging areas in the related field.

    Issues in sustainable supply chain's futuristic technologies: a bibliometric and research trend analysis.
    Ivan Darma Wangsa, Iwan Vanany, Nurhadi Siswanto.
      This paper presents a systematic review and bibliometric analysis in sustainable supply chain's futuristic technologies. The analysis involves 1596 articles published in the Scopus database from 1990 to 2020. The analysis examines the research outcomes by observing trends in journals, authorship, and keywords. The outcomes are visualized using VOSviewer to show the graphical network of co-authorship and the author's keywords. The results show that this research area has been a growing trend since 2016 and by 2020. The Journal of Cleaner Production was a leading journal in this area between 2016 and 2020, followed by Sustainability (Switzerland). The content analysis led to a classification of the articles into four main categories and sub-categories. The strategic diagram is used to reveal the emerging research themes analysis during the last 5 years (2016-2020) and to present future research. The data trending or emerging shows that technologies such as the technology by using combustion energy, renewable energy, and electric vehicles have been developing substantially. The research hotspots of the sustainable supply chain include, i.e., life cycle assessment (LCA), green investment, and carbon tax. Finally, the analysis also shows the research gaps that point a direction for future research.Graphical abstract.

    Zhifeng Lin, Xiaohui Ji, Nana Tian, Yu Gan, Li Ke.
      Background: Emerging research suggests that long non-coding RNAs (lncRNAs) play an important role in a variety of developmental or physiological processes of hepatocellular carcinoma (HCC). Various differentially expressed lncRNAs have been identified in HCC. Thus, a deeper analysis of recent research concerning lncRNA and HCC development could provide scientists with a valuable reference for future studies. Methods: Related publications were retrieved from the Web of Science Core Collection database. CiteSpace version 5.6.R4 was employed to conduct bibliometric analysis. Several network maps were constructed to evaluate the collaborations between different countries, institutions, authors, journals, and keywords. Results: A total of 2,667 records were initially found from the year of 2010-2020. The annual related publications output had increased dramatically during these years. Although China was the most prolific country in terms of research publication, the United States played a leading role in collaborative network. The Nanjing Medical University was the most productive institute in the field of lncRNAs in HCC development. Gang Chen was the most prolific researcher, while Yang F was the most frequently co-cited author. Oncotarget, Cell, and Oncogene were the most highly co-cited journals. The most recent burst keywords were interaction, database, and pathway. Conclusion: This study provides a comprehensive overview for the field of lncRNAs in HCC development based on bibliometric and visualized methods. The results would provide a reference for scholars focusing on this field.

    Bibliometric analysis of microbial sulfonamide degradation: Development, hotspots and trend directions.
    Luping Zeng, Wanxuan Li, Xiaoyan Wang, Yixin Zhang, Yiping Tai, Xiaomeng Zhang, Yunv Dai, Ran Tao, Yang Yang.
      Microbial sulfonamide degradation (MSD) is an efficient and safe treatment in both natural and engineered ecosystems. In order to systematically understand the research status and frontier trends of MSD, this study employed CiteSpace to conduct a bibliometric analysis of data from the Web of Science (WoS) and the China National Knowledge Infrastructure (CNKI) published from 2000 to 2021. During this time, China, Germany, Spain, the United States and Australia played leading roles by producing numerous high impact publications, while the Chinese Academy of Sciences was the leading research institution in this interdisciplinary research category. The Chemosphere was the top journal in terms of the number of citations. MSD research has gradually progressed from basic laboratory-based experiments to more complex environmental microbial communities and finally to deeper research on molecular mechanisms and engineering applications. Although multi-omics and synthetic community are the key techniques in the frontier research, they are also the current challenges in this field. A summary of published articles shows that Proteobacteria, Gammaproteobacteria, Burkholderiales and Alcaligenaceae are the most frequently observed MSD phylum, class, order and family, respectively, while Bacillus, Pseudomonas and Achromobacter are the top three MSD genera. To our knowledge, this study is the first to investigate the development and current challenges of MSD research, put forward future perspective, and form a relatively complete list of sulfonamide-degrading microorganisms for reference.

    Global research activity on mathematical modeling of transmission and control of 23 selected infectious disease outbreak.
    Waleed M Sweileh.
      BACKGROUND: Mathematical analysis and modeling allow policymakers to understand and predict the dynamics of an infectious disease under several different scenarios. The current study aimed to analyze global research activity on mathematical modeling of transmission and control of several infectious diseases with a known history of serious outbreaks.METHODS: Relevant publications were retrieved using a comprehensive validated search query. The database used was SciVerse Scopus. Indicators related to evolution, growth of publications, infectious diseases encountered, key players, citations, and international research collaboration were presented.
    RESULTS: The search strategy found 5606. The growth of publications started in 1967 and showed a sharp rise in 2020 and 2021. The retrieved articles received relatively high citations (h-index = 158). Despite being multidisciplinary, Plos One journal made the highest contribution to the field. The main findings of the study are summarized as follows: (a) COVID-19 had a strong impact on the number of publications in the field, specifically during the years 2020 and 2021; (b) research in the field was published in a wide range of journals, mainly those in the field of infectious diseases and mathematical sciences; (c) research in the field was mainly published by scholars in the United States and the United Kingdom; (d) international research collaboration between active countries and less developed countries was poor; (e) research activity relied on research groups with a large number of researchers per group indicative of good author-author collaboration; (f) HIV/AIDS, coronavirus disease, influenza, and malaria were the most frequently researched diseases; (g) recently published articles on COVID-19 received the highest number of citations; and (h) researchers in the Eastern Mediterranian and South-East Asian regions made the least contribution to the retrieved articles.
    CONCLUSION: Mathematical modeling is gaining popularity as a tool for understanding the dynamics of infectious diseases. The application of mathematical modeling on new emerging infectious disease outbreaks is a priority. Research collaboration with less developed countries in the field of mathematical epidemiology is needed and should be prioritized and funded.

    COVID-19 and Pregnancy: Citation Network Analysis and Evidence Synthesis.
    Rebeca Ruiz-Roman, Clara Martinez-Perez, Inés Gil Prados, Ignacio Cristobal Garcia, Miguel Ángel Sánchez-Tena.
      BACKGROUND: COVID-19 spread quickly around the world shortly after the first outbreaks of the new coronavirus disease that occurred at the end of December 2019, affecting all types of population, including pregnant women.OBJECTIVE: This study aims to analyze the relationship between different publications and their authors through citation networks, as well as to identify the research areas and determine which publication has been the most cited.
    METHODS: The search for publications was carried out through the Web of Science database using terms such as "pregnancy", "SARS-CoV-2", "pregnant"and"COVID-19" for the period between January and Decemeber 2020. The Citation Network Explorer software was used for publication analysis and the VOSviewer software was used for obtaining figures. This has enabled an in-depth network analysis to visualize the connections between the related elements and explain their network structure.
    RESULTS: A total of 1330 publications and 5531 citation networks were found in the search, with July being the month with the largest number of publications, and United States, China and England the countries with the greatest number of publications. The most cited publication was "Clinical characteristics and intrauterine vertical transmission potential of COVID-19 infection in nine pregnant" by Chen et al., published in March 2020. Six groups identified by being close in the citation network comprise multidisciplinary research, including clinical characteristics and outcomes in pregnancy, vertical transmission, delivery mode, and psychological impact of the pandemic on pregnant women.
    CONCLUSIONS: Thousands of articles on COVID-19 have been published in several journals since the disease started. Identifying relevant publications and getting a global view of the main papers on COVID-19 and pregnancy, leads to a better understanding of the topic. Thanks to scientific knowledge we now know the clinical features of COVID-19 during pregnancy are generally similar to infected non-pregnant women. There is a small increase in frequency of preterm birth and cesarean birth, related to severe maternal illness. Vaccination for all pregnant women is recommended. Several agents are being evaluated for treatment of COVID-19, with minimal or no information on safety in pregnancy. These results could form the basis for further research. Future bibliometric and scientometric studies on COVID-19 should provide updated information to analyze other relevant indicators in this field.

    Scientometric Analysis of Public Health Emergencies: 1994-2020.
    Jing Liu, Yujie Wang, Qian Zhang, Jianxiang Wei, Haihua Zhou.
      The purpose of this paper is to summarize the research hotspots and frontiers in the field of public health emergencies (PHE) between 1994-2020 through the scientometric analysis method. In total, 2247 literature works retrieved from the Web of Science core database were analyzed by CiteSpace software, and the results were displayed in knowledge mapping. The overall characteristics analysis showed that the number of publications and authors in the field of PHE kept an upward trend during the past decades, and the United States was in the leading position, followed by China and England. Switzerland has the highest central value and plays an important intermediary role in promoting the integration and exchange of international PHE research achievements. The keyword co-occurrence analysis indicated that COVID-19 was the most high-frequency keyword in this field, and there had been no new keywords for a long time until the outbreak of COVID-19 in 2019. The burst detection analysis showed that the top five burst keywords in terms of burst intensity were zika virus, Ebola, United States, emergency preparedness and microcephaly. The results indicated that the research theme of PHE is closely related to the major infectious diseases in a specific period. It will continue to develop with more attention paid to public health. The conclusions can provide help and reference for the PHE potential researchers.

    An overview of ecological vulnerability: a bibliometric analysis based on the Web of Science database.
    Yue Chen, Kangning Xiong, Xiaodong Ren, Cai Cheng.
      Ecological vulnerability has become one of the hot issues of ecology and environmental science under global change and sustainable development scenarios. However, no study quantitatively analyzes the global scientific performance and hot research areas in this field by adopting the bibliometric method. Based on 935 pieces of literature retrieved from the Web of Science database, we comprehensively analyzed the research on ecological vulnerability in terms of growth trend, research content, publication journal and country, and co-occurrence network of keywords. The results showed that research on ecological vulnerability had experienced rapid growth since 2000, while ecological vulnerability research at the World Heritage sites was still embryonic. The top two productive countries in ecological vulnerability research were America and China, and the top two productive journals were Ecological Indicators and Regional Environmental Change. Study on ecological vulnerability was mainly classified as empirical evaluation and regional synthesis, whereas theoretical research is rare. Based on the summary of the main progress and achievements in ecological vulnerability research, we proposed five scientific issues that remain to be resolved in the field of ecological vulnerability. Overall, this study could shed light on a comprehensive and systematic understanding of ecological vulnerability and provide directions for future research on ecological vulnerability in a rapidly changing world.

    The knowledge dissemination trajectory research of the carbon footprint domain: a main path analysis.
    Dejian Yu, Yitong Chen.
      The global warming caused by greenhouse gas emissions has received widespread attention from all around the world. In this regard, how to calculate the carbon footprint (CF) scientifically and accurately produced by human activities to achieve emission reduction goals has been widely discussed by scholars. In recent years, related research on this issue has increased, leading to a significant expand in the number of publications. It is necessary to excavate and summarize the current development status and possible future trends of this field based on quantitative methods. To achieve this goal, this paper develops a main path analysis (MPA) of the entire field and three research sub-topics (agriculture, energy fuels, and business economic) based on the 4973 papers extracted from Web of Science (WoS) database. The results show that the CF domain mainly focuses on optimizing the CF calculation methods from a theoretical perspective to improve the accuracy of estimation. Furthermore, scholars engaged in the agricultural research mainly focus on adjusting the life cycle assessment (LCA) model, which has advantage on microlevel CF accounting, according to actual needs to achieve more accurate predictions, while researchers who pay attention to the topic of business economic are committed to improving the input-output model, which is suitable for meso and macro analysis, to enhance accounting accuracy. In general, this article is beneficial for presenting the intellectual structure and knowledge diffusion trajectories of the CF domain from horizontal and vertical perspectives.

      The Tibetan Plateau works as an important environmental and ecological barrier for the Asian continent. The researches on Tibetan environment and ecology are becoming extensive, but there is no systematic summary of research hotspots and trends in this field. Here, we analyzed 9180 publications retrieved from the WOS and CNKI during 2000 ~ 2020. The characteristics of publication, keywords with a 5-year interval and co-occurrence analysis were carried out so as to reveal the evolution and development trends of topics. The results show that articles increase dramatically since 2012. Except for common concerns like evolution, climate change, and precipitation, diversity was been studied more by Chinese scholars, while the USA, Germany, UK, and Australia researchers focused more on adaptability, basin western Tibet, lake, barley, and ore-related themes, respectively. Besides, China closely collaborated with the USA, Australia, and Germany in topics of evolution, climate change and degradation, precipitation, and diversity. The institutions located in Chinese different economic regions focused on different research keywords, such as vegetation, growth, trace elements, and geochemistry. The CAS contributed the most articles with 4254, showed advantages both in quantity and quality. Few articles were published by researchers affiliated to Free University of Berlin but with higher citations. It is the only one institute outside of China in the top 20. Main research hotspots include climate change, geology, and diversity. In future researches, ecological management and rehabilitation of mining area and tailings ponds, waste disposal, and changes of soil and water quality are worthy of attention and funding.

      Introduction: The emergent field of learning health systems (LHSs) has been rapidly evolving as the concept continues to be embraced by researchers, managers, and clinicians. This paper reports on a scoping review and bibliometric analysis of the LHS literature to identify key topic areas and examine the influence and spread of recent research.Methods: We conducted a scoping review of LHS literature published between January 2016 and May 2020. The authors extracted publication data (eg, journal, country, authors, citation count, keywords) and reviewed full-texts to identify: type of study (empirical, non-empirical, or review), degree of focus (general or specific), and the reference used when defining LHSs.
    Results: A total of 272 publications were included in this review. Almost two thirds (65.1%) of the included articles were non-empirical and over two-thirds (68.4%) were from authors in the United States. More than half of the publications focused on specific areas, for example: oncology, cardiovascular care, and genomic medicine. Other key topic areas included: ethics, research, quality improvement, and electronic health records. We identified that definitions of the LHS concept are converging; however, many papers focused on data platforms and analytical processes rather than organisational and behavioural factors to support change and learning activities.
    Conclusions: The literature on LHSs remains largely theoretical with definitions of LHSs focusing on technical processes to reuse data collected during the clinical process and embedding analysed data back into the system. A shift in the literature to empirical LHS studies with consideration of organisational and human factors is warranted.

    Climate Change and Zoonoses: A Review of Concepts, Definitions, and Bibliometrics.
    Walter Leal Filho, Linda Ternova, Sanika Arun Parasnis, Marina Kovaleva, Gustavo J Nagy.
      Climate change can have a complex impact that also influences human and animal health. For example, climate change alters the conditions for pathogens and vectors of zoonotic diseases. Signs of this are the increasing spread of the West Nile and Usutu viruses and the establishment of new vector species, such as specific mosquito and tick species, in Europe and other parts of the world. With these changes come new challenges for maintaining human and animal health. This paper reports on an analysis of the literature focused on a bibliometric analysis of the Scopus database and VOSviewer software for creating visualization maps which identifies the zoonotic health risks for humans and animals caused by climate change. The sources retained for the analysis totaled 428 and different thresholds (N) were established for each item varying from N 5 to 10. The main findings are as follows: First, published documents increased in 2009-2015 peaking in 2020. Second, the primary sources have changed since 2018, partly attributable to the increase in human health concerns due to human-to-human transmission. Third, the USA, the UK, Canada, Australia, Italy, and Germany perform most zoonosis research. For instance, sixty documents and only 17 countries analyzed for co-authorship analysis met the threshold led by the USA; the top four author keywords were "climate change", "zoonosis", "epidemiology", and "one health;" the USA, the UK, Germany, and Spain led the link strength (inter-collaboration); the author keywords showed that 37 out of the 1023 keywords met the threshold, and the authors' keyword's largest node of the bibliometric map contains the following: infectious diseases, emerging diseases, disease ecology, one health, surveillance, transmission, and wildlife. Finally, zoonotic diseases, which were documented in the literature in the past, have evolved, especially during the years 2010-2015, as evidenced by the sharp augmentation of publications addressing ad-hoc events and peaking in 2020 with the COVID-19 outbreak.

    Flash Sintering Research Perspective: A Bibliometric Analysis.
    Eva Gil-González, Luis A Pérez-Maqueda, Pedro E Sánchez-Jiménez, Antonio Perejón.
      Flash Sintering (FS), a relatively new Field-Assisted Sintering Technique (FAST) for ceramic processing, was proposed for the first time in 2010 by Prof. Rishi Raj's group from the University of Colorado at Boulder. It quickly grabbed the attention of the scientific community and since then, the field has rapidly evolved, constituting a true milestone in materials processing with the number of publications growing year by year. Moreover, nowadays, there is already a scientific community devoted to FS. In this work, a general picture of the scientific landscape of FS is drawn by bibliometric analysis. The target sources, the most relevant documents, hot and trending topics as well as the social networking of FS are unveiled. A separate bibliometric analysis is also provided for Reaction or Reactive Flash Sintering (RFS), where not only the sintering, but also the synthesis is merged into a single step. To the best of our knowledge, this is the first study of this nature carried out in this field of research and it can constitute a useful tool for researchers to be quickly updated with FS as well as to strategize future research and publishing approaches.

    A Bibliometric Analysis of Mexican Bioinformatics: A Portrait of Actors, Structure, and Dynamics.
    Dagoberto Armenta-Medina, Christian Díaz de León Castañeda, Alma Armenta-Medina, Ernesto Perez-Rueda.
      Bioinformatics is a very important informatics tool for health and biological sciences, focusing on biological data management. The objective of this work was to perform a bibliometric analysis regarding the development of Mexican bioinformatics. An exhaustive revision of the literature associated with Mexican bioinformatics in a period of 25-years was performed. Bibliometric tools, such as performance analysis and science mapping were included in the analysis. We identified the main actors as well as the structure and dynamics of Mexican bioinformatics. Some of the main findings were as follows: the thematic structure in the field is defined by the research lines of outstanding authors; the outstanding collaborations of Mexican institutions with foreign countries and institutions are influenced by the geographic proximity and binational agreements, as well as philanthropic and academic programs that promote collaborations, and there is an inclination for health issues promoted by public health financing and philanthropic organizations. It is identified that publications had an explosion since 2012, we consider that this growth may be influenced by the democratization of data, derived from the mass sequencing of biological molecules stored in public databases.

    Andrew M Pattock, Michelle Minna Kim, Cooper B Kersey, Linda Liu, James N Kirkpatrick, Adeyinka Adedipe, Ross Kessler, Amy Morris, Sara Nikravan, Sula Mazimba, Younghoon Kwon.
      INTRODUCTION: Cardiac point-of-care ultrasound (c-POCUS) is an increasingly implemented diagnostic tool with the potential to guide clinical management. We sought to characterize and analyze the existing c-POCUS literature with a focus on the temporal trends and differences across specialties.METHODS: A literature search for c-POCUS and related terms was conducted using Ovid (MEDLINE and Embase) and Web of Science databases through 2020. Eligible publications were classified by publication type and topic, author specialty, geographical region of senior author, and journal specialty.
    RESULTS: The initial search produced 1761 potential publications. A strict definition of c-POCUS yielded a final total of 574 cardiac POCUS manuscripts. A yearly increase in c-POCUS publications was observed. Nearly half of publications were original research (48.8%) followed by case report or series (22.8%). Most publications had an emergency medicine senior author (38.5%), followed by cardiology (20.8%), anesthesiology (12.5%), and critical care (12.5%). The proportion authored by emergency medicine and cardiologists has decreased over time while those by anesthesiology and critical care has generally increased, particularly over the last decade. First authorship demonstrated a similar trend. Articles were published in emergency medicine (24.4%) and cardiology journals (20.5%) with comparable frequency.
    CONCLUSION: The annual number of c-POCUS publications has steadily increased over time, reflecting the increased recognition and utilization of c-POCUS. This study can help inform clinicians of the current state of c-POCUS and augment the discussion surrounding barriers to continued adoption across all specialties.

    Bibliometric Analysis of the Informal Caregiver's Scientific Production.
    Bruno Ferreira, Ana Diz, Paulo Silva, Luís Sousa, Lara Pinho, César Fonseca, Manuel Lopes.
      (1) Background: Due to the increase in care needs, especially in the elderly, the concept of caregiver has emerged. This concept has undergone changes over the years due to new approaches and new research in the area. It is in this context that the concept of informal caregiver emerged. (2) Objectives: To analyse the evolution of the caregiver concept. (3) Methods: Bibliometric analysis, data collection (Web of Science Core Collection) and analysis (Excel; CiteSpace; VOSviewer). (4) Results: Obtained 22,326 articles. The concept emerged in 1990, being subjected to changes, mostly using the term "informal caregiver" since 2016, frequently related to the areas of Gerontology and Nursing. The following research boundaries emerged from the analysis: "Alzheimer's Disease", "Elderly" and "Institutionalization". (5) Conclusions: The informal caregiver emerges as a useful care partner, being increasingly studied by the scientific community, particularly in the last 5 years.

    Bibliometric Study of Scientific Productivity on the Impacts on Mental Health in Times of Pandemic.
    Luz Marina Caballero-Apaza, Rubén Vidal-Espinoza, Silvia Curaca-Arroyo, Rossana Gomez-Campos, Zaida Callata-Gallegos, José Fuentes-López, Marco Cossio-Bolaños.
      Background and Objectives: The presence of the new SARS-CoV-2 virus is causing enormous threats to people's health and lives, so quantifying the scientific productivity on mental health in times of pandemic is an urgent need, especially to expand the degree of knowledge on mental health problems in regions of low scientific productivity. The aim was to characterize the bibliometric indicators of scientific productivity on mental health during the pandemic in the PubMed Identifier database of the National Library of Medicine in the United States. Materials and Methods: A documentary study (bibliometric) of the scientific productivity on mental health in times of pandemic from January 2020 to June 2021 was carried out. The PubMed database was used to abstract the information from the original scientific articles. The data abstracted were: authors, year of publication, journal name, country, and language of publication. Results: We identified 47 original articles worldwide, which were published in 29 journals and in three languages (English, Spanish, and German). We observed three groups of countries that published on mental health topics. The first group comprised the largest number of publications, which were multicenter studies (six studies), followed by India (five studies), and Italy (four studies). A second group comprised Bangladesh, China, USA, and Spain, with 3 studies each; and a third group comprised 13 countries (Albania, Saudi Arabia, Argentina, Brazil, South Korea, Denmark, Ecuador, Egypt, Greece, Japan, Jordan, Kuwait, and New Zealand) with one study each. Conclusions: Bibliometric indicators of scientific productivity on mental health during the COVID-19 pandemic have ostensibly increased. We verified 47 studies in PubMed, which could serve to improve the understanding and management of COVID-19, as well as serve as a thought-provoking means for other countries and researchers to publish on the state of mental health during and post pandemic.

    Trends in Publication Speed of Radiation Oncology Research from 2010 to 2019.
    Michael K Rooney, Eric G Nesbit, Emma B Holliday, Reshma Jagsi, Clifton D Fuller, Ethan B Ludmir, Sean Sachdev.
      Purpose: In this investigation, we aimed to describe trends in time to acceptance (TTA) and time to online publication (TTOP) of research published in leading radiation oncology journals from 2010 to 2019. We further sought to identify journal characteristics that might influence TTA and TTOP.Methods and Materials: We searched the publication history of 5 leading international radiation oncology journals. For all research articles accepted from January 1, 2010, to December 31, 2019, we tabulated the date of article receipt, the date of acceptance, and the date of online publication when available. The TTA was calculated as the number of elapsed days from article receipt to acceptance, and the TTOP was calculated as the number of elapsed days from article acceptance to online publication. Using the Mann-Kendall test, we assessed for monotonic trends over time and used the post hoc Theil-Sen method to estimate rates of change. We created a multiple regression model to identify journal characteristics associated with TTA and TTOP.
    Results: In total, 10,132 articles were included. Both the TTA and the TTOP decreased significantly from 2010 to 2019 (P = .005 and P < .001, respectively), with an estimated decrease of 1.5 days per year for the TTA and 7.0 days per year for the TTOP. Multiple regression modeling revealed that a higher journal impact factor was independently associated with an increased TTA (P < .001) and a decreased TTOP (P < .001). A higher number of accepted journal articles per year was associated with a decreased TTA (P < .001) and an increased TTOP (P < .001).
    Conclusions: Radiation oncology research has been accepted and published online at increasingly faster rates during the past decade. The TTA may be longer in higher-impact, more selective journals, possibly suggesting a need for comprehensive peer review and complex editorial decisions. However, these articles are also published online faster after article acceptance. Future work examining patterns of acceptance and publication speed is needed to encourage rapid dissemination of practice-guiding data.

    A Bibliometric Analysis on Global Psychological and Behavioral Research Landscape on COVID-19 Pandemic.
    Xilu Dong, Xuqiu Wei, Fei Shu, Qiang Su, Juntao Wang, Ning Liu, Junping Qiu.
      The COVID-19 pandemic outbreak in December 2019 has spread globally. The ongoing psychological and behavioral effects of the COVID-19 pandemic, which poses a major challenge to humanity, are of concern to researchers. To understand the academic community's attention, focus and research collaboration on psychological and behavioral research during the COVID-19 pandemic, we conducted a macro analysis using a bibliometric approach. Using the topic selection strategy of TS = ("COVID-19" OR "coronavirus disease 2019" OR "SARS-CoV-2" OR "2019-nCoV") AND TS = ("behavio*") AND TS = ("psycholog*"), 2096 high-quality research articles and reviews were downloaded as data from the Web of Science core collection on 16 November 2021. Through analysis and visualization, the following conclusions are drawn in this study: (1) The popularity and importance of psychological and behavioral research under COVID-19 has increased significantly and needs further attention; (2). Related research focuses on eight hotspots, with quarantine, health care workers, the elderly, students, pregnant women, family, consumers, social media and emergency preparedness knowledge as the focus of the research object; and (3) Research collaboration is relatively high at the author, organizational and national levels. However, low-income countries need to get more attention. Furthermore, this article would help researchers make decisions for the research of psychological and behavioral issues under COVID-19 and planning for future prospects to contribute to academic development and applied methodology.

    A Protocol for a Scoping Review Comparative Bibliometric Analysis of Infectious Disease Research in Africa.
    Adrianna Perryman, Gebremedhin Beedemariam Gebretekle, Adeteju Ogunbameru, Joanna M Bielecki, Beate Sander.
      Introduction: Evidence on authorship trends of health research conducted about or in Africa shows that there is a lack of local researchers in the first and last authorship positions, with high income country collaborations taking up these positions. The differences in authorship calls into question power imbalances in global health research and who benefits from the production of new discoveries and innovations. Health studies may further go on to inform policy and clinical practice within the region having an impact on public health. This paper aims to compare the differences in authorship between COVID-19 and relevant infectious diseases in Africa. Materials and Methods: We will conduct a bibliometric analysis comparing authorship for COVID-19 research during a public health emergency with authorship for four other infectious diseases of relevance to Africa namely: Ebola, Zika Virus (ZIKV), Tuberculosis (TB) and Influenza. Our scoping review will follow the framework developed by Arksey and O'Malley and reviewed by Levac et al. We will search MEDLINE (Ovid), African Index Medicus (AIM), Eastern Mediterranean Region (IMEMR) Index Medicus, Embase (Ovid), and Web of Science (Clarivate). We will compare the different trends of disease research between the selected diseases. This study is registered with OSF registries and is licensed with the Academic Free License version 3.0.

    Are we there yet? A systematic literature review of Open Educational Resources in Africa: A combined content and bibliometric analysis.
    Ahmed Tlili, Fahriye Altinay, Ronghuai Huang, Zehra Altinay, Jako Olivier, Sanjaya Mishra, Mohamed Jemni, Daniel Burgos.
      Although several studies have been conducted to summarize the progress of open educational resources (OER) in specific regions, only a limited number of studies summarize OER in Africa. Therefore, this paper presents a systematic literature review to explore trends, themes, and patterns in this emerging area of study, using content and bibliometric analysis. Findings indicated three major strands of OER research in Africa: (1) OER adoption is only limited to specific African countries, calling for more research and collaboration between African countries in this field to ensure educational equity; (2) most of the OER initiatives in Africa have focused on the creation process and neglected other important perspectives, such as dissemination and open educational practices (OEP) using OER; and (3) on top of the typical challenges for OER adoption (e.g., infrastructure), other personal challenges were identified within the African context, including culture, language, and personality. The findings of this study suggest that more initiatives and cross-collaborations with African and non-African countries in the field of OER are needed to facilitate OER adoption in the region. Additionally, it is suggested that researchers and practitioners should consider individual differences, such as language, personality and culture, when promoting and designing OER for different African countries. Finally, the findings can promote social justice by providing insights and future research paths that different stakeholders (e.g., policy makers, educators, practitioners, etc.) should focus on to promote OER in Africa.

    Presentation at the Canadian Association of Radiologists Annual General Meeting Is Associated With Higher Likelihood of Publication of Canadian Radiology Resident Research Day Presentations.
    Martin Matuszczak, Sarah Melendez, David A Leswick.
      Objective: Determine how many radiology resident research day projects are presented at the Canadian Association of Radiologists Annual Scientific Meeting (CAR ASM) and if presentation at the CAR ASM is associated with increased rates of publication. Methods: A database of radiology resident presentations from 2012 to 2017 research days at seven Canadian radiology programs was utilized. Each presenting resident was searched for in 2011-2019 CAR ASM books of abstracts to identify all CAR ASM presentations both related to and separate from their research day projects. These presentations were matched with resident research day presentations and their publication status. Descriptive statistical analysis and calculation of relative risk (RR) between publication of research day projects and presentation at CAR was performed. Results: 208 residents presented 288 projects at internal research days. 93 of the 208 residents had a total of 195 presentations at CAR (mean .94 +/- 1.91 SD). 36 of the 288 (13%) research day projects were presented at a CAR ASM, of which 18/36 (50%) were published. 83 of the 252 (32%) research day projects not presented at CAR were published. CAR ASM presentation of a research day project was associated with an increased rate of publication (RR 1.537 P=.0396). There was no significant association between research day project publication and unrelated CAR ASM presentations (P=.275). Most research day projects both presented at CAR ASM and published (56%) were in the Canadian Association of Radiologists Journal. Conclusion: CAR ASM presentation of research day projects is associated with an increased rate of publication.

    Analysis of co-authorship networks among Brazilian graduate programs in computer science.
    Alex Nunes da Silva, Matheus Montanini Breve, Jesús Pascual Mena-Chalco, Fabrício Martins Lopes.
      The growth and popularization of platforms on scientific production has been the subject of several studies, producing relevant analyses of co-authorship behavior among groups of researchers. Researchers and their scientific productions can be analysed as co-authorship social networks, so researchers are linked through common publications. In this context, co-authoring networks can be analysed to find patterns that can describe or characterize them. This work presents the analysis and characterization of co-authorship networks of academic Brazilian graduate programs in computer science. Data from Brazilian researchers were collected and modeled as co-authoring networks among the graduate programs that researchers take part in. Each network topology was analysed with complex network measurements and three proposed qualitative indices that evaluate the publication's quality. In addition, the co-authorship networks of the computer science graduate programs were characterized in relation to the assessment received by CAPES, which attributes a qualitative grade to the graduate programs in Brazil. The results show the most relevant topological measurements for the program's characterization and the evaluations received by the programs in different qualitative degrees, relating the main topological patterns of the co-authorship networks and the CAPES grades of the Brazilian graduate programs in computer science.

    Diversifying history: A large-scale analysis of changes in researcher demographics and scholarly agendas.
    Stephan Risi, Mathias W Nielsen, Emma Kerr, Emer Brady, Lanu Kim, Daniel A McFarland, Dan Jurafsky, James Zou, Londa Schiebinger.
      BACKGROUND: In recent years, interest has grown in whether and to what extent demographic diversity sparks discovery and innovation in research. At the same time, topic modeling has been employed to discover differences in what women and men write about. This study engages these two strands of scholarship to explore associations between changing researcher demographics and research questions asked in the discipline of history. Specifically, we analyze developments in history as women entered the field.METHODS: We focus on author gender in diachronic analysis of history dissertations from 1980 (when online data is first available) to 2015 and a select set of general history journals from 1950 to 2015. We use correlated topic modeling and network visualizations to map developments in research agendas over time and to examine how women and men have contributed to these developments.
    RESULTS: Our summary snapshot of aggregate interests of women and men for the period 1950 to 2015 identifies new topics associated with women authors: gender and women's history, body history, family and households, consumption and consumerism, and sexuality. Diachronic analysis demonstrates that while women pioneered topics such as gender and women's history or the history of sexuality, these topics broaden over time to become methodological frameworks that historians widely embraced and that changed in interesting ways as men engaged with them. Our analysis of history dissertations surface correlations between advisor/advisee gender pairings and choice of dissertation topic.
    CONCLUSIONS: Overall, this quantitative longitudinal study suggests that the growth in women historians has coincided with the broadening of research agendas and an increased sensitivity to new topics and methodologies in the field.

    Making Biomedical Sciences publications more accessible for machines.
    Joris Van Meenen, Hanne Leysen, Hongyu Chen, Rudi Baccarne, Deborah Walter, Bronwen Martin, Stuart Maudsley.
      With the rapidly expanding catalogue of scientific publications, especially within the Biomedical Sciences field, it is becoming increasingly difficult for researchers to search for, read or even interpret emerging scientific findings. PubMed, just one of the current biomedical data repositories, comprises over 33 million citations for biomedical research, and over 2500 publications are added each day. To further strengthen the impact biomedical research, we suggest that there should be more synergy between publications and machines. By bringing machines into the realm of research and publication, we can greatly augment the assessment, investigation and cataloging of the biomedical literary corpus. The effective application of machine-based manuscript assessment and interpretation is now crucial, and potentially stands as the most effective way for researchers to comprehend and process the tsunami of biomedical data and literature. Many biomedical manuscripts are currently published online in poorly searchable document types, with figures and data presented in formats that are partially inaccessible to machine-based approaches. The structure and format of biomedical manuscripts should be adapted to facilitate machine-assisted interrogation of this important literary corpus. In this context, it is important to embrace the concept that biomedical scientists should also write manuscripts that can be read by machines. It is likely that an enhanced human-machine synergy in reading biomedical publications will greatly enhance biomedical data retrieval and reveal novel insights into complex datasets.

    Internationalizing AI: evolution and impact of distance factors.
    Xuli Tang, Xin Li, Feicheng Ma.
      International collaboration has become imperative in the field of AI. However, few studies exist concerning how distance factors have affected the international collaboration in AI research. In this study, we investigate this problem by using 1,294,644 AI related collaborative papers harvested from the Microsoft Academic Graph dataset. A framework including 13 indicators to quantify the distance factors between countries from 5 perspectives (i.e., geographic distance, economic distance, cultural distance, academic distance, and industrial distance) is proposed. The relationships were conducted by the methods of descriptive analysis and regression analysis. The results show that international collaboration in the field of AI today is not prevalent (only 15.7%). All the separations in international collaborations have increased over years, except for the cultural distance in masculinity/felinity dimension and the industrial distance. The geographic distance, economic distance and academic distances have shown significantly negative relationships with the degree of international collaborations in the field of AI. The industrial distance has a significant positive relationship with the degree of international collaboration in the field of AI. Also, the results demonstrate that the participation of the United States and China have promoted the international collaboration in the field of AI. This study provides a comprehensive understanding of internationalizing AI research in geographic, economic, cultural, academic, and industrial aspects.Supplementary Information: The online version contains supplementary material available at 10.1007/s11192-021-04207-3.
