    Global nursing research activity from 2009 to 2020: A bibliometric analysis.
    Cui Wang, Yuexian Shi, Han Lu, Xu Dong, Luoya Hou, Limin Wang, Qiaoqin Wan, Li Hu, Lei Zhang, Dou Dou, Shaomei Shang.
       AIM: Bibliometric analysis of the nursing literature can provide insights into the current state and dynamics of the nursing profession. This study aimed to assess global nursing-related research activity from 2009 to 2020.
    METHOD: The corpus of nursing papers was harvested from the Web of Science Core Collection database. The bibliometric indicators and VOSviewer mapping of the retrieved papers were presented.
    RESULTS: The search found 109,782 papers, and 39.0% of papers reported funded studies. Publication numbers were increasing. The USA was the most prolific country in literature production and international collaboration in nursing studies. International cooperation in nursing research was dominated by developed regions. Among the 20 most cited articles, 75% were published in first quartile journals, and review papers received a higher number of citations than original research articles. Author keyword analysis identified 'quality of life', 'mental health', 'nursing students' education' and 'adolescent' as common nursing focus topics.
    CONCLUSIONS: The publication trend of nursing papers was positive. However, several problems were associated with nursing research activity, including low research funding, regionally centred research activity and inactivity of developing regions in terms of international collaborations, which need to be addressed by policy makers, nursing managers and scholars.

    Top 100 Most-Cited Articles on Enhanced Recovery After Surgery: A Bibliometric Analysis and Visualized Study.
    Liping He, Lulu Lu, Shengjie Su, Qiang Lin, Chan Sheng.
       Background: The enhanced recovery after surgery (ERAS) protocol is widely implemented in surgeries, and this study aims to reveal the characteristics of the 100 most-cited original articles in the field of ERAS research.
    Methods: The literature was retrieved in the Web of Science database, the 100 most-cited original articles were identified, and their characteristics were analyzed, including the trends of publications and citations; contributions from countries, institutions, and authors; co-cited authors and journals in the references; served surgeries, research endpoints, keywords; and the level of evidence.
    Results: There was a rising trend in the yearly publications and citations. Denmark and the USA contributed the largest number of highly cited papers. The University of Copenhagen was the most influential institution. Kehlet, Henrik was the most influential author. The British Journal of Surgery was the most often published and cited journal. ERAS protocols were overwhelmingly implemented in colorectal surgeries. The most focused endpoints were "length of stay", "complications", and "readmission". The most frequently used keywords were "fast track", "length of stay", and "laparoscopy". The keyword "enhanced recovery after surgery" burst since 2012. More than half of the highly cited articles presented level IV evidence, but there was no correlation between citations (densities) and the levels of evidence.
    Conclusions: The highly cited research overwhelming implemented ERAS in colorectal surgeries, the "length of stay" was the most focused element, and Kehlet, Henrik was the most influential researcher. Most of the highly cited ERAS had low levels of evidence, and the total number of citations was not relevant to the level of evidence. Therefore, studies with high levels of evidence are still required in the future.

    Current Status of and Global Trends in Platelet Transfusion Refractoriness From 2004 to 2021: A Bibliometric Analysis.
    Ying Liu, Yufan Zhang, Dawei Chen, Yongshui Fu.
      Platelet transfusion refractoriness (PTR) is common in patients with hematology and oncology and is becoming an important barrier in the treatment of thrombocytopenia and hemorrhage. Bibliometrics is an effective method for identifying existing research achievements, important breakthroughs, current research hotspots, and future development trends in any given field. In recent years, research on PTR has received increasing attention, but a bibliometric analysis of this field has not yet been reported. In this study, we applied bibliometrics to analyze the existing literature on PTR research over the past 17 years. On November 1, 2021, we began a publications analysis of PTR research using the Science Citation Index Expanded of the Web of Science Core Collection with collection dates from 2004 to 2021. This research aimed to summarize the state of PTR research using Bibliometrix to identify connections between different elements (i.e., authors, institutions, countries, journals, references, and keywords) using VOS viewer analyses to visualize key topics and trends in PTR research using Cite Space and gCLUTO. The results of all 310 studies showed that the annual number of publications focused on PTR is steadily increasing, with the United States of America and Japan making significant contributions. We noted that the research group led by Dr. Sherrill J. Slichter was prominent in this field, while Estcourt Lise may become the most influential newcomer. Transfusion was the most popular journal, and Blood was the most cited journal. Using various analyses, including co-cited analysis, historiography analysis, citation burst analysis, and factorial analysis, we pointed out and discussed contributing publications. According to occurrence analysis, co-word biclustering analysis, landform map, thematic evolution, and thematic map, we believe that "activation," "p-selection," "CD36 deficiency," "gene-frequencies," "CD109," "HPA-1," and "beta (3) integrin" may become new trends in PTR research. The outcome of our bibliometric analyses has, for the first time, revealed profound insights into the current state and trends in PTR research. The systematic analysis provided by our study clearly demonstrates the field's significant advancements to all researchers who are interested in a quick and comprehensive introduction to the field.

    Han Qing Xu, Chih-Chao Chung, Cheng Yu.
      Recently, cultural neuroscience has gained attention as a new, important, and interdisciplinary topic in the field of neuroscience. It helps us understand the interaction of cultural and biological factors over the course of life. This study aims to provide a comprehensive overview of the field to readers and potential researchers engaged in cultural neuroscience research. A bibliometric analysis was performed on 113 articles in the field of cultural neuroscience from 2008 to 2021 using data from the core collection of Web of Science. Network visualization software VOSviewer and ITGInsight were used for performance analysis and science mapping. Specifically, the performance analysis included countries, institutions, authors, papers, and journals, while science mapping analyzed the collaboration network, keyword network, bibliographic coupling network, and time series evolution. The results showed that the United States was the most productive country, Northwestern University was the most influential research institution, Chiao Jy was the most influential scholar, and "Social Cognitive and Affective Neuroscience" made the greatest contribution to publishing in the field of cultural neuroscience. Furthermore, collaboration is expected to be the development trend in the future. The key research topics in the field of cultural neuroscience included neuroimaging and psychiatric diseases, theoretical methods, interdisciplinary research, cultural differences (collectivism and individualism), and brain functions. Finally, future research will focus on cultural neuroscience, culture, and self, while adolescence will be the emerging research frontier.

    A bibliometric analysis of research trends in life cycle assessment of fresh concrete and mortar during 1997-2021.
    Mohammad Reza Sabour, Ehsan Asheghian Amiri, Mohammadamin Akbari, Amin Sadeghi-Sheshdeh.
      The construction industry relies heavily on concrete as a fundamental material. According to the shift towards environmental sustainability in recent years, studies on life cycle assessment (LCA) of concrete and mortar and reducing their environmental impacts have increased significantly. This paper provides insights into studies performed in LCA of fresh concrete and mortar until 2021 by using a bibliometric method. To achieve this goal, 283 documents were selected from the Scopus database for bibliometric analysis. VOSviewer and Publish or Perish tools were used to perform bibliometric analysis and data visualization. Various aspects of existing documents, including top sources, countries, and authors, were analyzed. Citation analysis was conducted to identify articles with the most citations. Co-occurrence analysis has been used for analyzing keywords to identify research trends and future research directions. The number of studies in this area has grown significantly in recent years, according to the results. Among all subject areas, engineering and environmental science are recognized as the main areas of existing researches. Journal of Cleaner Production is one of the leading journals in this field. Among the productive countries, the USA is recognized as the leader. However, de Brito J. from Portugal is the most prolific author in this field. The most influential document in this field was written by Habert et al., which includes the highest citations among all documents. Keyword analysis indicates that "Fly Ash" has the most occurrence among all keywords. However, "Recycled Aggregates" recorded the highest annual average growth rate in recent years.

    A bibliometric analysis of the cannabis and cannabinoid research literature.
    Jeremy Y Ng, Nathan Chang.
       BACKGROUND: Cannabis refers to a plant in the family Cannabaceae, which has been used medically, recreationally, and industrially. The last two decades, in particular, have seen a large increase in the volume of literature on this topic. The present bibliometric analysis aims to capture the characteristics of scholarly journal publications on the topic of cannabis and cannabinoid research.
    METHODS: Searches were run on the Scopus database on April 02, 2021, as follows "(TITLE (cannabi* OR hashish OR marijuana OR marihuana)) AND ( LIMIT-TO ( DOCTYPE,"ar" ) OR LIMIT-TO ( DOCTYPE,"re" ) )". Results were exported on the same day to prevent discrepancies between daily database updates. Only "article" and "review" publication types were included; no further search limits were applied. The "article" publication type includes publications featuring original research, whereas "review" includes reviews and conference papers. The following data were collected: number of publications (in total and per year), authors, and journals; open access status; publications per journal; journals publishing the highest volume of literature and their impact factors, language of publication; document type; publication country; author affiliations; funding sponsors; most highly cited publications; and most highly published authors. Trends in this subset of publications were identified and presented. Bibliometric networks were constructed using the software tool VOSviewer.
    RESULTS: A total of 29 802 publications (10 214 open access), published by 65 109 authors, were published in 5474 journals from 1829 to 2021. The greatest number of publications was published over the last 20 years. The journal that published the largest number of publications was Drug and Alcohol Dependence (n = 705). The most productive countries included the USA (n = 12 420), the UK (n = 2236), and Canada (n = 2062); many of the most common institutional affiliations and funding sponsors originated from these countries.
    CONCLUSIONS: The number of publications published on the topic of cannabis follows an upward trend. Over the past 20 years, the volume of cannabis research has grown steeply, which can be attributed to a large amount of funding dedicated to researching this topic. Future research should continue to investigate changes in the publication characteristics of emerging research, as the volume of publications on this topic is expected to rapidly grow.

      Salivary biomarkers are indicators of many biological and pathological conditions and provide further information regarding the early detection of diseases. This bibliometric analysis aims to identify and evaluate the scientific literature addressing salivary biomarkers from a dental perspective, to identify the most prolific organizations, authors, journals, countries, and keywords used within this research domain. An electronic search was performed using Elsevier's Scopus database. From a total of 587 retrieved papers (published between 1997 and 2021), 399 were selected. For the data analysis and its visualization, the title of the articles, year of publication, countries, authors, journals, articles, and keywords were analyzed using Microsoft Excel and VOSviewer (a bibliometric software program). An increase in the number of publications was identified from 1997 to 2021. The United States (U.S.) published the most papers (84) and received the highest citations (3778), followed by India and Brazil. The Journal of Periodontology published the highest number of articles (39) that received the highest citations. The University of Kentucky from the U.S. published most of the papers related to salivary biomarkers that received the highest citations. Timo Sorsa published the most papers (14 papers), while Craig Miller was the highest cited author (754 citations). Concerning the highly cited papers, a paper by Micheal et al., published in 2010, received the highest citations (487 citations). "Saliva", followed by "human", were the most common keywords used by the authors in the papers related to salivary biomarkers. The findings of this analysis revealed an increase in salivary biomarker-related publications that positively influenced the number of citations each paper received. The U.S. produced the most publications that received the highest citations, and the University of Kentucky, U.S., was the most prominent. The articles were mostly published in the Journal of Periodontology and received the highest number of citations.

       OBJECTIVE: The aim of the study was to quantitatively analyze the scientific literature landscape covering legal regulations of patient safety.
    METHODS: This retrospective bibliometric analysis queried Web of Science database to identify relevant publications. The identified scientific literature was quantitatively evaluated to reveal prevailing study themes, contributing journals, countries, institutions, and authors, as well as citation patterns.
    RESULTS: The identified 1295 publications had a mean of 13.8 citations per publication and an h-index of 57. Approximately 78.8% of them were published since 2010, with the United States being the top contributor and having the greatest publication growth. A total of 79.2% (n = 1025) of the publications were original articles, and 12.5% (n = 162) were reviews. The top authors (by number of publications published on the topic) were based in the United States and Spain and formed 3 collaboration clusters. The top institutions by number of published articles were mainly based in the United States and United Kingdom, with Harvard University being on top. Internal medicine, surgery, and nursing were the most recurring clinical disciplines. Among 4 distinct approaches to improve patient safety, reforms of the liability system (n = 91) were most frequently covered, followed by new forms of regulation (n = 73), increasing transparency (n = 67), and financial incentives (n = 38).
    CONCLUSIONS: Approximately 78.8% of the publications on patient safety and its legal implications were published since 2010, and the United States was the top contributor. Approximately 79.2% of the publications were original articles, whereas 12.5% were reviews. Healthcare sciences services was the most recurring journal category, with internal medicine, surgery, and nursing being the most recurring clinical disciplines. Key relevant laws around the globe were identified from the literature set, with some examples highlighted from the United States, Germany, Italy, France, Sweden, Poland, and Indonesia. Our findings highlight the evolving nature and the diversity of legislative regulations at international scale and underline the importance of healthcare workers to be aware of the development and latest advancement in this field and to understand that different requirements are established in different jurisdictions so as to safeguard the necessary standards of patient safety.

       Background: Stereotactic and functional neurosurgery (SFN) is a rapidly evolving field and some emerging countries, especially Mexico, have made significant contributions to this discipline. A bibliometric analysis has never been performed in Latin America, and this would be particularly important to show the areas that remain poorly studied, and design research strategies for the future.
    Methods: Scopus was queried using keywords pertaining to functional neurosurgery, restricting the affiliation country to Mexico, and considering documents published after 1949. Added to the initial search, a complementary literature exploration by author, considering the publications of the most productive neurosurgeons, was performed. A descriptive statistical analysis was carried out.
    Results: From 5,109 articles, only 371 were eligible. Scientific production has gradually increased with time. Epilepsy (31%) and movement disorders (27.4%) were the most studied neurological conditions, whereas the other 41.6% corresponded to pain, behavior disorders, spinal cord injuries, neuromodulation, stereotactic biopsies, and SFN history. Level of evidence was predominantly level V (59.1%). Publication output is highly skewed to Mexico City, which represents 78.4% of national production. Relative to factors associated with impact of research, publications in English had more citations (28.5 mean citations per paper), and journals with an impact factor greater than one had more than 10 mean citations per paper.
    Conclusions: Mexico has experienced an increase in the productivity of SFN literature, addressing the most prevalent issues in the country (epilepsy and motor disorders). However, it is necessary to report studies with a higher level of evidence, as well as to decentralize the research collaborating with national institutions outside Mexico City. On the other hand, it is imperative to promote scientific production in English and in high-impact indexed journals to increase the visibility of our production. We would like to call upon our colleagues in other countries to reproduce our methodology, in order to determine the factors associated with the impact and productivity on SFN research.

    Gender Authorship Trends Among Craniofacial Publications: A 20-Year Analysis.
    Fei Wang, Tiffany Cheng, Joseph A Ricci.
      This study aims to identify gender disparities within the subspecialty of craniofacial surgery as women surgeons remain underrepresented in academia and leadership, arenas heavily dictated by research productivity.
    All craniofacial articles published in 3 major research journals from 2000 to 2020 were reviewed and evaluated in 5-year increments.
    Information regarding author gender, authorship distribution, geographic origin, and publication type was collected. ANOVA, χ2, and logistic regression modeling were used for analysis.
    In total, there were 3684 articles with 15 206 total authors-3128 (20.6%) were women, including 665 (21.3%) first authors, 1980 (63.2%) middle authors, and 487 (15.7%) senior authors. Mean women authorship increased significantly from 2000 to 2020 (0.33 vs 1.22 P < .001) with corresponding significant increases in first and senior authorship (8.63% vs 27.02; 5.65% vs 16.13%; P < .001). Statistically significant trends across time were observed for first and senior authorships (P < .001). Women were more likely to publish original publications as first and senior authors (OR: 1.83, P < .001; OR: 1.37, P = .0012). Women were less likely to publish editorial articles (OR 0.6, P < .001). The United States ranked third in publication output by female first authors but was behind all regions except Africa for output by female senior authors.
    Although female authorship has increased significantly over the last 2 decades, women remain a minority within the craniofacial literature. Further research is needed to elicit the root of these disparities.

    Trends, Issues and Future Directions of Urban Health Impact Assessment Research: A Systematic Review and Bibliometric Analysis.
    Wenbing Luo, Zhongping Deng, Shihu Zhong, Mingjun Deng.
      Health impact assessment (HIA) has been regarded as an important means and tool for urban planning to promote public health and further promote the integration of health concept. This paper aimed to help scientifically to understand the current situation of urban HIA research, analyze its discipline co-occurrence, publication characteristics, partnership, influence, keyword co-occurrence, co-citation, and structural variation. Based on the ISI Web database, this paper used a bibliometric method to analyze 2215 articles related to urban HIA published from 2012 to 2021. We found that the main research directions in the field were Environmental Sciences and Public Environmental Occupational Health; China contributed most articles, the Tehran University of Medical Sciences was the most influential institution, Science of the Total Environment was the most influential journal, Yousefi M was the most influential author. The main hotspots include health risk assessment, source appointment, contamination, exposure, particulate matter, heavy metals and urban soils in 2012-2021; road dust, source apposition, polycyclic aromatic hydrocarbons, air pollution, urban topsoil and the north China plain were always hot research topics in 2012-2021, drinking water and water quality became research topics of great concern in 2017-2021. There were 25 articles with strong transformation potential during 2020-2021, but most papers carried out research on the health risk assessment of toxic elements in soil and dust. Finally, we also discussed the limitations of this paper and the direction of bibliometric analysis of urban HIA in the future.

    Assessment of the correlation, if any, between twitter mentions and academic citations in emergency medicine journals.
    Huseyin Avni Demir, Serkan Dogan.
       INTRODUCTION: Twitter may be used in disseminating scientific information that can be measured via citations by traditional systems. We aimed to investigate the relationship between Twitter mentions, traditional citations including Google Scholar and Scopus, and the metric value of Altmetric for articles published in emergency medicine journals.
    METHODS: Articles published in emergency medicine journals between January 2018 and June 2018 were retrospectively analyzed in February 2021. Journals included with an impact factor of >1 and indexed in Q1. Metric data about citations in Google Scholar and Scopus, the metric value of the Altmetric system, and Twitter mentions were obtained.
    RESULTS: There were 502 articles published in different seven emergency medicine journals. Fifty-four articles (10.8%) were never cited in Google Scholar or Scopus. There were 79 articles (15.7%) without Twitter mention. Twitter mentions as a tweet or no tweet impacted the number of articles with citation (p > 0.05). The number of citations per article was significantly higher in articles with Twitter mentions (p = 0.002 for Google Scholar citations, p = 0.005 for Scopus citations). Altmetric cited articles were significantly higher for articles with Twitter mentions (p < 0.001). There were significant positive correlations between the number of Twitter mentions and citations in Scopus (r = 0.30, p < 0.001), in both Google Scholar and Scopus (r = 0.19, p < 0.001), and in Altmetrics (r = 0.852, p < 0.001).
    CONCLUSION: There were positive correlations between numbers of Twitter mentions, traditional citations, including Google Scholar and Scopus, and metric values of the Altmetric system. This finding supports that increased social media citations are associated with increased dissemination and disclosure of publications.

    Disparities in Regional Publication Trends on the Topic of Artificial Intelligence in Biomedical Science Over the Last Five Years: A Bibliometric Analysis.
    Kirubel Biruk Shiferaw, Dagmar Waltemath, Atinkut Zeleke.
      Bibliometric analysis is a scientific method that allows researchers to explore the current trend in a certain research area using citation information. This study aims to provide a meta-view of artificial intelligence studies focused on biomedicine in the last five years, which will provide an insight into current trends and future research directions. Besides the observation of increased publication rates in the area of AI in biomedicine, the results indicate a lower contribution from and a sparser network connectivity of countries with limited resources. Thus, working toward collaboration in terms of infrastructure and implementing alternative solutions such as FAIR (Findable, Accessible, Interoperable and Reproducible) and open access platforms could improve the collaborative nature of international health projects.

    A Bibliometric Analysis of Knowledge-Hiding Research.
    Qing Xia, Shumin Yan, Heng Li, Kaifeng Duan, Yuliang Zhang.
      Knowledge hiding, defined as an intentional attempt to conceal requested knowledge, has become a hot topic in management and psychology in the last decade. Emerging research has suggested that knowledge hiding is not simply the opposite of knowledge sharing, such that it is crucial to clarify the concept, explore the research progress and development trend of knowledge hiding. Based on 243 relevant articles, a bibliometric analysis of knowledge-hiding research is presented via descriptive, keyword and citation analysis. Results reveal that knowledge-hiding research, mainly focusing on the disciplines of management, business and psychology, is currently in a period of rapid growth, especially in the past two or three years. The systematic review of knowledge-hiding research enables us intuitively to obtain a panoramic view, including publication performance, thematic evolution and most influential topics of the field via a set of science maps, enabling future authors to investigate knowledge hiding and focus their research more effectively.

    A Scientometric Review of Soft Robotics: Intellectual Structures and Emerging Trends Analysis (2010-2021).
    Yitong Zhou, Haonan Li.
      Within the last decade, soft robotics has attracted an increasing attention from both academia and industry. Although multiple literature reviews of the whole soft robotics field have been conducted, there still appears to be a lack of systematic investigation of the intellectual structure and evolution of this field considering the increasing amount of publications. This paper conducts a scientometric review of the progressively synthesized network derived from 10,504 bibliographic records using a topic search on soft robotics from 2010 to 2021 based on the Web of Science (WoS) core database. The results are presented from both the general data analysis of included papers (e.g., relevant journals, citation, h-index, year, institution, country, disciplines) and the specific data analysis corresponding to main disciplines and topics, and more importantly, emerging trends. CiteSpace, a data visualization software, which can construct the co-citation network maps and provide citation bursts, is used to explore the intellectual structures and emerging trends of the soft robotics field. In addition, this paper offers a demonstration of an effective analytical method for evaluating enormous publication citation and co-citation data. Findings of this review can be used as a reference for future research in soft robotics and relevant topics.

    Gender representation on journal editorial boards in the field of veterinary sciences.
    Althea Wang, Rebecca Dunlop, Rachel Allavena, Chiara Palmieri.
      Despite the increased entry of women into the veterinary profession over the past several decades, women remain substantially underrepresented in senior leadership positions. This may include editorial positions at veterinary sciences journals. This study examines the gender distribution of editorships of 143 journals from the Thomson Reuters Web of Knowledge Journal Citation Reports category of veterinary science. The gender analysis was performed by impact factor, editorial board role, country and publisher. Females were underrepresented in the group of managing editors (32.2% females vs 67.2% males), editors (34.5% females vs 65.1% males) and others (33.3% females vs. 65.4% males). The journal impact factor did not have a significant impact on the proportion of males versus females on the editorial board. The median publisher had 27.5% editorships belonging to women. North America Europe and Oceania showed the greatest representation of women on editorial boards. Our findings provide the first measure of gender distribution on editorial boards in the veterinary sciences and may stimulate a discussion on the current situation of women in academic positions and, in particular, on editorial boards. Further research should investigate the underlying causes contributing to this aspect of gender inequality and identify possible strategies to encourage a greater participation of women to editorial boards.

    COVID-19 citation pandemic within the psychological knowledge domain.
    Dejan Pajić.
      Presented study explores the knowledge domain of psychological research published in 2020 and 2021. Metadata from 156,942 psychology papers available in Scopus were analyzed using citation analysis and bibliographic mapping techniques. Having in mind the ubiquity of the COVID-19 pandemic and the numerous ways it has affected people's lives, the fact that COVID-19-related papers represent only 2% to 7% of the total academic production in psychology may seem rather low. However, these papers have attracted much more attention from the public than non-COVID papers. They were also cited two to eight times more frequently, depending on the measure used, and account for 16% to 19% of total citations to psychology papers. Results show that early-stage researchers and those who had fewer articles in Scopus have benefited more from publishing COVID papers. They have managed to boost their average citation rates to the level of their colleagues who were much longer active and previously had higher citedness. Results indicate that the authors citing behavior largely follows the cumulative advantage pattern. Psychological research in general is mainly focused on mental health, anxiety, depression, and stress. This trend is even more fostered due to the pandemic since some of these topics are often analyzed as typical emotional reactions to COVID-19. Other relevant issues are also very well covered, except for the question how scientific results are communicated to the public. The role of "hot" papers was elaborated from the perspective of research evaluation practice.

    A bibliometric analysis of online faculty professional development in higher education.
    Yanjun Gao, Su Luan Wong, Mas Nida Md Khambari, Nooreen Noordin.
      Research on online faculty professional development (OFPD) in higher education has increased in recent years. As there is, nevertheless, a scarcity of quantitative investigations on research publications in this area, a bibliometric analysis of 248 publications collected from the Scopus database was conducted. Biblioshiny and VOSviewer software tools were used for descriptive and network analyses. The research results showed that the overall trend of publication in this domain increased steadily at an annual growth rate of 14.11% during the past 25 years. Journal of Asynchronous Learning Network and Computers and Education ranked the highest among journals with regard to publication number and citation number, respectively. With a total of 298 citations to his paper, Peter Shea was ranked the most impactful author while Maria Northcote, with five publications, was the most productive. In terms of geographical location of research activity, America played the leading role, with Asia emerging in this field. The publication entitled "A Research Agenda for Online Teacher Professional Development" by Dede et al. topped the list for both total citations and average yearly citations. As to recent trends, teacher professional development through online teaching was emergent partly due to the outbreak of Covid-19. Pedagogy training, online community building, and facilitating online teachers were the themes that researchers favored. The study will contribute toward better understanding of the existing literary landscape of research on OFPD given the potential of OFPD in enhancing faculty's effectiveness in their classrooms and over the course of their teaching careers.

    Mapping Research Knowledge on Rice Husk Ash Application in Concrete: A Scientometric Review.
    Muhammad Nasir Amin, Waqas Ahmad, Kaffayatullah Khan, Mohamed Mahmoud Sayed.
      This study aimed to carry out a scientometric review of rice husk ash (RHA) concrete to assess the various aspects of the literature. Conventional review studies have limitations in terms of their capacity to connect disparate portions of the literature in a comprehensive and accurate manner. Science mapping, co-occurrence, and co-citation are a few of the most difficult phases of advanced research. The sources with the most articles, co-occurrences of keywords, the most prolific authors in terms of publications and citations, and areas actively involved in RHA concrete research are identified during the analysis. The Scopus database was used to extract bibliometric data for 917 publications that were then analyzed using the VOSviewer (version: 1.6.17) application. This study will benefit academics in establishing joint ventures and sharing innovative ideas and strategies because of the statistical and graphical representation of contributing authors and countries.

    The Colombian scientific elite-Science mapping and a comparison with Nobel Prize laureates using a composite citation indicator.
    Julián D Cortés, Daniel A Andrade.
      A well-established agenda on the research output, impact, and structure of global scientific elites such as Nobel Prize laureates has generated interest in the scientific elites from developing countries. However, this topic has not been investigated in detail. This study, first, deploys science mapping techniques to provide a comprehensive analysis of the output, impact, and structure of the Colombian scientific elite, i.e., researchers awarded with the Alejandro Ángel Escobar Foundation National Prize 1990-2020, known locally as the Colombian Nobel. Second, we conducted a productivity and impact comparison between the Colombian scientific elite and Nobel Prize laureates in science and economics by means of a stratified random sample 1990-2020 via the composite citation indicator proposed by Ioannidis et al. Findings showed that the Colombian scientific elite has a broader agenda than indexing titles in internationally renowned bibliographic databases. The Colombian scientific elite also showed positive growth, which is an inverse trend compared with the sample of Nobel laureate productivity. There were no noticeable changes in productivity/impact before and after receiving the Alejandro Ángel Escobar Foundation National Prize. Institutional collaboration within the Colombian scientific elite displayed the highest betweenness (brokerage) role of world/local top-tier universities. However, only two Colombian scientific elite members published an article with two Nobel Prize laureates. Most of the research profiles reflected the national output priorities, but were found to diverge from the national focus in respect of strategic research capacities. The interleaving of the Colombian scientific elite and Nobel Prize laureates-particularly between the 3rd and 2nd quartiles-enabled a more nuanced analysis of the local impact in the global scientific landscape. Our findings also contrast with previous findings on the lower research impact of authors from Latin America, despite their involvement as contributors to reputable journals, and also shed light on the research performance-impact standards and agenda between the global North and South and provide an in-context assessment of outstanding local research.

       INTRODUCTION: While breast reconstruction has become more and more important within the past decade, research focus areas as well as trends are in constant change.
    METHOD: The publications from 2012 to 2021 were retrieved from the Web of Science Core Collection database. CiteSpace visualization analysis software was used to analyze the institutions, countries, regions, categories, and keywords on breast reconstruction research.
    RESULT: A total of 3092 articles were selected. The number of articles published in the last 10 years showed an upward trend year by year. The journal "Plastic and Reconstructive Surgery" had the largest number of publications and citations, representing the core journal. The USA had the largest number of publications and the most extensive cooperation with other countries. The research highlights mainly focused on the improvement of surgical techniques, enhancing postoperative recovery, and oncological safety.
    CONCLUSION: Over the past decade, research on breast reconstruction has developed steadily, and considerable achievements in the field of surgical techniques, postoperative recovery, and oncological safety were reached. Plastic surgeons should continue to strive for a higher level of evidence study designs, while also recognizing the importance of international and multiple-center cooperation.

    The Application of Angiotensin Receptor Neprilysin Inhibitor in Cardiovascular Diseases: A Bibliometric Review From 2000 to 2022.
    Xia Xu, Yumeng Li, Shuqing Shi, Jiayu Lv, Yajiao Wang, Haoran Zheng, Xinxin Mao, Huaqin Wu, Bingxuan Zhang, Qingqiao Song.
      Cardiovascular disease (CVD) has become a huge challenge for the global public health system due to its high morbidity, mortality and severe economic burden. In recent years, angiotensin receptor neprilysin inhibitor (ARNI), a new class of drugs, has shown good therapeutic effects on CVD patients in several clinical studies, reducing the morbidity and mortality of CVD patients. In this study, we retrieved publications on ARNI research in the cardiovascular field from the Web of Science core collection and analyzed the annual output, spatial and temporal distribution, institutions and authors, core journals, keywords and co-cited literature based on CiteSpace. As a result, 604 publications were retrieved, and the number of annual publications generally increased year by year, with the largest number of articles. The analysis of the co-occurrence of output countries and authors showed that a few developed countries such as the United States, Canada, and United Kingdom are the most active in this field, forming academic groups represented by John Joseph Valentine McMurray and Scott D. Solomon, and New England Journal of Medicine, Cirulation, and Journal of the American College of Cardiology are the most popular journals in the field, with research hotspots focused on ARNI in the treatment of total ejection fraction heart failure, hypertension and its target organ damage, with the potential for future benefit throughout the cardiovascular event chain as research progresses. This study reveals the prospective application of ARNI in the cardiovascular field and the research hotspots, providing broader and deeper guidance for its use in the clinic, which is beneficial to improve the treatment and prognosis of CVD patients.

    A Bibliometric Analysis of the Literature on Irisin from 2012-2021.
    Jiangshan Liu, Bote Qi, Lin Gan, Yanli Shen, Yu Zou.
      Irisin is a hormone-like molecule mainly released by skeletal muscles in response to exercise, which is proposed to induce the 'browning' of white adipose tissue. Since its identification, irisin was reported to be closely associated with many metabolic diseases, including type 2 diabetes mellitus (T2DM), obesity, cardiovascular disease (CVD), and metabolic bone diseases. In recent years, irisin has attracted increasing research interest, and numerous studies have been published in this field. Thus, it is essential to identify the current research status of irisin and measure research hotspots and possible future trends. In this study, by utilizing two visualization software named CiteSpace and VOSviewer, we analyzed 1510 Web of Science publications on irisin published from 2012 to 2021. Our results show that the number of irisin-related articles published annually has increased significantly. China participates in the most studies, followed by the United States and Turkey. Firat University, Harvard University, and Shandong University are three major institutions with larger numbers of publications. The analysis of keywords co-occurrence indicates that insulin resistance, inflammation, and circulating irisin levels in serum are the research hotspots. Apoptosis, BDNF, and osteoporosis will likely become the focus of future research related to irisin. Overall, this study may provide helpful insights for researchers to understand the current research situation and identify the potential frontiers of irisin.

    A Bibliometric Analysis of Research on Selenium in Drinking Water during the 1990-2021 Period: Treatment Options for Selenium Removal.
    Ricardo Abejón.
      A bibliometric analysis based on the Scopus database was carried out to summarize the global research related to selenium in drinking water from 1990 to 2021 and identify the quantitative characteristics of the research in this period. The results from the analysis revealed that the number of accumulated publications followed a quadratic growth, which confirmed the relevance this research topic is gaining during the last years. High research efforts have been invested to define safe selenium content in drinking water, since the insufficient or excessive intake of selenium and the corresponding effects on human health are only separated by a narrow margin. Some important research features of the four main technologies most frequently used to remove selenium from drinking water (coagulation, flocculation and precipitation followed by filtration; adsorption and ion exchange; membrane-based processes and biological treatments) were compiled in this work. Although the search of technological options to remove selenium from drinking water is less intensive than the search of solutions to reduce and eliminate the presence of other pollutants, adsorption was the alternative that has received the most attention according to the research trends during the studied period, followed by membrane technologies, while biological methods require further research efforts to promote their implementation.

    Artificial intelligence in E-Commerce: a bibliometric study and literature review.
    Ransome Epie Bawack, Samuel Fosso Wamba, Kevin Daniel André Carillo, Shahriar Akter.
      This paper synthesises research on artificial intelligence (AI) in e-commerce and proposes guidelines on how information systems (IS) research could contribute to this research stream. To this end, the innovative approach of combining bibliometric analysis with an extensive literature review was used. Bibliometric data from 4335 documents were analysed, and 229 articles published in leading IS journals were reviewed. The bibliometric analysis revealed that research on AI in e-commerce focuses primarily on recommender systems.

    A Global Perspective of Vibrio Species and Associated Diseases: Three-Decade Meta-Synthesis of Research Advancement.
    Hope Onohuean, Ezera Agwu, U U Nwodo.
      Outbreaks of Vibrio infections have a long history of global public health concern and threat to the aquaculture industry. This 3-decade (1990-2019) meta-synthesis of global research progress in Vibrio species and associated disease outbreaks was undertaken to generate the knowledge needed to design effective interventions with policy implications. Using PRISMA protocol, we obtained data on the online version of the Institute for Scientific Information (ISI), Web of Science (WOS), and Scopus from January 1990 to September 2021 by title search of the keywords "Vibrio species OR Vibrio spp. OR vibriosis." On the 3-decade survey, the result has shown that a total of 776 publications document types were published on the subject, with an average of 24.25 ± 13.6 published documents per year with an annual growth rate of 4.71%. The year 2020 recorded the highest output of 52 published documents accounting for 6.70% of the total. The most prolific author, Blanch A., published 12 articles on the subject and has received citations of 1003 with an h-index of 10. While the most global cited paper author is the journal of J. Bacteriol (Bassler et al), receiving total citation (TC) (550) and per Year (22). The top active corresponding authors country is the United States of America with (92) articles, freq. 12.40%; TC of 3103. The observations in this study, such as the collaborations network map, and index, which have outlined a big difference between countries based on economic status, have underscored the need for a sustained research mentorship program that can define future policies.

    Top 25 cited articles on Covid-19 and IBD: A bibliometric analysis.
    Ido Veisman, Noam Brakin Lederer, Offir Ukashi, Uri Kopylov, Eyal Klang.
       OBJECTIVES: The use of citation analysis to identify the most cited covid-19 and inflammatory bowel disease (IBD) manuscripts to provide an insight into the advances and knowledge accumulated regarding the pandemic in this subgroup of patients.
    METHODS: We've used a public application programming interface (API) U.S. National Center for Biotechnology Information (NCBI) to access the PubMed database. Data lock was performed on April 19, 2022. The API was used to retrieve all available IBD AND Covid-19 -related entries. For each retrieved entry, we've also obtained its citation count.
    RESULTS: The top 25 manuscripts were published between 2020 and 2021. The total citation count is 2051. The citation count of articles ranged from 41 to 313. The top 25 manuscripts were published in eight journals, while 16 were published in Gastroenterology and Gut. 36% of the most cited manuscripts reported clinical characteristics and patient outcomes, and 32% dealt with patient management. The most impactful manuscripts provided evidence that IBD patients are not at increased risk for severe morbidity or mortality from Covid-19 and that it is not advisable to discontinue the anti-inflammatory treatment for IBD during the pandemic. Two basic science studies demonstrated mechanistic insights for these observations. Studies that examined the immunogenic response of IBD patients treated with biologics were also part of the top-cited list.
    CONCLUSIONS: Impactful scientific publications on Covid-19 in IBD patients provided reassurance and directed treatment at the time of this newly recognized severe disease.

    Association between academic degrees and research productivity: an assessment of Canadian academic general surgeons.
    Kieran Purich, Kevin Verhoeff, Alexander Miles, Janice Y Kung, A M James Shapiro, David Bigam.
       BACKGROUND: For academic hiring committees and surgical trainees, the benefits of a graduate degree are unclear. We sought to identify if graduate degrees or professorship status were associated with increased research productivity among Canadian academic surgeons.
    METHODS: We included general surgeons from the largest hospitals associated with accredited residency programs. We classified staff surgeons active between 2013 and 2018 by degree (MD only, master's degree, PhD) and professorship (assistant, associate, professor) status. We identified their publications from January 2013 to December 2018. Variables of interest included publications per year, citations per article, journal of publication, CiteScore, author's Hirsch (h) index and the revised h-index (r-index). We used Kruskal-Wallis tests and the Dunn multiple comparison test to assess statistical significance.
    RESULTS: We identified 3262 publications from 187 surgeons, including 78 (41.7%) with no graduate degree, 84 (44.9%) with master's degrees and 25 (13.4%) with PhDs. Surgeons with graduate degrees had more publications per year, higher CiteScores, more citations per article, and higher h- and r-indices than those without graduate degrees. Surgeons with doctorates had the highest median values in all domains, but differences were not significant compared with surgeons with master's degrees. Seventy-seven (41.8%) surgeons were assistant professors, 63 (34.2%) were associate professors and 44 (23.9%) were full professors. Statistically, full professors had a greater number of publications per year and higher h- and r-indices than their counterparts.
    CONCLUSION: Surgeons with graduate degrees or more advanced professorships had the greatest research productivity. Surgeons with doctorates trended toward greater research productivity than those holding master's degrees.

    Trends in Apomixis Research: The 10 Most Cited Research Articles Published in the Pregenomic and Genomic Eras.
    Fabio Palumbo, Samela Draga, Alessandro Vannozzi, Margherita Lucchin, Gianni Barcaccia.
      Apomixis, or asexual reproduction by seed, represents an easy shortcut for life cycle renewal based on maternal embryo production without ploidy reduction (meiosis) and ploidy restitution (syngamy). Although the first studies officially published on this topic in scientific journals date back to the early 1930s, the identification and introduction of genes involved in asexual reproduction in species of agronomic interest still represent a major challenge. Through a bibliometric analysis of the research programs implemented in apomixis over the last 40 years, the present study was aimed to discuss not only the main findings achieved but also the investigational methods and model species used. We split the critical survey of the most cited original articles into pregenomic and genomic eras to identify potential trends and depict scenarios that have emerged in the scientific community working on apomixis, as well as to determine any correlation between the exponential increase in acquired basic knowledge and the development of advanced analytical technologies. This review found a substantial stagnation in the use of the same model species, with few exceptions, for at least 40 years. In contrast, the development of new molecular techniques, genomic platforms, and repositories has directly affected the approaches used in research, which has been directed toward an increasingly focused study of the genetic and epigenetic determinants of apomixis.

    Types of Errors Hiding in Google Scholar Data.
    Romy Sauvayre.
      Google Scholar (GS) is a free tool that may be used by researchers to analyze citations; find appropriate literature; or evaluate the quality of an author or a contender for tenure, promotion, a faculty position, funding, or research grants. GS has become a major bibliographic and citation database. For assessing the literature, databases, such as PubMed, PsycINFO, Scopus, and Web of Science, can be used in place of GS because they are more reliable. The aim of this study was to examine the accuracy of citation data collected from GS and provide a comprehensive description of the errors and miscounts identified. For this purpose, 281 documents that cited 2 specific works were retrieved via Publish or Perish software (PoP) and were examined. This work studied the false-positive issue inherent in the analysis of neuroimaging data. The results revealed an unprecedented error rate, with 279 of 281 (99.3%) examined references containing at least one error. Nonacademic documents tended to contain more errors than academic publications (U=5117.0; P<.001). This viewpoint article, based on a case study examining GS data accuracy, shows that GS data not only fail to be accurate but also potentially expose researchers, who would use these data without verification, to substantial biases in their analyses and results. Further work must be conducted to assess the consequences of using GS data extracted by PoP.

    Academia's responses to crisis: A bibliometric analysis of literature on online learning in higher education during COVID-19.
    Ling Zhang, Richard Allen Carter, Xueqin Qian, Sohyun Yang, James Rujimora, Shuman Wen.
      This paper aimed to provide a holistic view of research that investigated online learning in higher education around the globe during COVID-19 utilizing a bibliometric analysis. The researchers used co-citation analysis and text mining afforded by VOSviewer to document and analyze research patterns and topics reported in peer-reviewed documents published between January 2020 and August 2021. Findings of this study indicated that scholars from 103 countries or regions from the Global North and Global South investigated a wide array of topics, such as use of various technologies and strategies, redesigned curriculum, student perceptions and psychological impacts of the pandemic-imposed online learning. Many researchers applied technology acceptance theories and structural equation modeling to investigate factors associated with adoption and impacts of the pandemic-imposed online learning. Of the large quantity of research, medical education and chemical education were the most investigated disciplines. Inquiry-based learning, discovery learning, hands-on learning and collaborative learning emerged as instructional approaches frequently discussed or utilized across the target studies. This paper discussed (a) ongoing and emerging challenges to online higher education, (b) placing innovative pedagogies at the forefront of online learning, and (c) rapid, but imbalanced distribution of evolving literature based on the findings.

    Bibliometric Analyses of Web of Science Illuminate Research Advances of Neuropterida.
    Shuo Tian, Yuxin An, Ruyue Zhang, Liming Wang, Yuyu Wang.
      Neuropterida is a relatively primitive group of Holometabola. There are about 6500 extant species. Many species of this group are natural enemies and can prey on a variety of agricultural pests. In order to understand the leading research institutions, researchers and research contents, and to predict the future research directions of Neuropterida, the Web of Science core database, from January 1995 to September 2021, was searched with the theme of "Neuropterida or Neuroptera or Megaloptera or Raphidioptera or Lacewing". The results showed that the United States and China published relatively more publications than other countries. In addition, researchers from these two countries had more cooperation with other countries. China Agricultural University ranked the highest in the number of publications and centrality in this field. In addition, it was found that the early research focused on the biological control of Neuropterida by analyzing the keyword burst, whereas the more recent research focused on the phylogeny of Neuropterida. As the first representative chromosome-level genome of Neuropterida has been published, the future research of Neuropterida will focus on the genomic studies and molecular mechanisms of their morphological characters, behavior, historical evolution and so on.

    Trends and Hotspots in Nanoparticles for the Targeted Delivery of Nucleic Acids: A Ten-Year Bibliometric Study.
    Yingzhao Huang, Qi Zhan, Chenzhou Wu, Nailin Liao, Zhou Jiang, Haoran Ding, Kunyu Wang, Yi Li.
      Nanoparticles for the gene therapy field have seen remarkable progress over the last 10 years; however, low delivery efficiency and other reasons impede the clinical translation of nanocarriers. Therefore, a summary of hotspots and trends in this field is needed to promote further research development. In this research, from 2011 to 2021, 1,221 full records and cited references of Web of Science-indexed manuscripts regarding nanoparticle-targeted delivery systems have been analyzed by CiteSpace, VOSviewer, and MapEquation. In these software, keywords co-occurrence networks, alluvial diagram, co-citation networks, and structural variation analysis were carried out to emphasize the scientific community's focus on nanomedicine of targeted delivering of nucleic acids. Keywords such as transfection efficiency, tumor cell, membrane antigen, and siRNA delivery were highlighted in the density map from VOSviewer. In addition, an alluvial flow diagram was constructed to detect changes in concepts. In the co-citation network, cluster 1 (exosomes) and cluster 17 (genome editing) were new research fields, and the efforts in modifying nanoparticles were revealed in the structural variation analysis. Aptamer and SELEX (systematic evolution of ligands by exponential enrichment) represented a helpful system in targeted delivery. These results indicated that the transfection efficiency of nanocarriers required continuous improvements. With the approval of several nucleic acid drugs, a new content of nanoparticle carriers is to introduce gene-editing technology, especially CRISPR/Cas9 (clustered regularly interspaced short palindromic repeats/CRISPR-associated protein 9). In addition, exosomes have great potential as targeted nanoparticles. By mapping the knowledge domains of nanomedicine in targeted delivering of nucleic acids, this study analyzed the intellectual structure of this domain in the recent 10 years, highlighting classical modifications on nanoparticles and estimating future trends for researchers and decision-makers interested in this field.

    Cristina Candal-Pedreira, Alberto Ruano-Ravina, Julia Rey-Brandariz, Nerea Mourino, Sofia Ravara, Pedro Aguiar, Mónica Pérez-Ríos.
      The retraction of health sciences publications is a growing concern. To understand the patterns in a particular country-context and design specific measures to address the problem, it is important to describe and characterise retractions. We aimed to assess the evolution of health science retractions in Brazil and Portugal and to describe their features. We conducted a cross-sectional study including all health sciences retracted articles with at least one author affiliated to a Portuguese or Brazilian institution identified through Retraction Watch database.A total of 182 retracted articles published in 129 journals were identified. The number of retractions increased over time, but the proportion related to the whole of publications remained stable. A total of 50.0% and 60.8% of the Portuguese and Brazilian retracted articles, respectively, were published in first and second quartile journals. Scientific misconduct accounted for 60.1% and 55.9% of retractions in Brazil and Portugal, respectively. In both countries, the most frequent cause of misconduct was plagiarism. 61.8% and 53.4% of the Portuguese and Brazilian retracted articles, respectively, included a funding declaration and, of those, 90.3% and 88.6% received funding. The time from publication to retraction decreases as the journal quartile increases. Articles retracted for misconduct received more citations than those retracted for error.The retraction of health sciences articles did not decrease over time in Brazil and Portugal. There is a need to develop strategies aimed at preventing, monitoring and managing scientific misconduct according to the country context.

    A bibliometric analysis of Community of Inquiry in online learning contexts over twenty-five years.
    Zhonggen Yu, Ming Li.
      Since the outbreak of COVID-19, online learning has gained popularity among educators and learners, where Community of Inquiry (CoI) has caught researchers' attention. To bibliometrically analyze the framework of CoI over twenty-five years, we adopted both qualitative and quantitative research methods to examine the framework of CoI in online learning contexts. We concluded that teaching presence, social presence, cognitive presence, metacognition, and self-efficacy played important roles in the framework of CoI. This study also explored the top ten authors, sources, organizations, and countries using VOSviewer and established citation networks through the clustering techniques in CitNetExplorer. Future research could focus on how to motivate the educational institutes and educators to change their traditional educational methods and whether to include both metacognition and self-efficacy in the CoI framework.

    Technical advances on current research trends and explore the future scope on nutrient recovery from waste-streams: a review and bibliometric analysis from 2000 to 2020.
    Tuhin Kamilya, Rajneesh Kumar Gautam, Shobha Muthukumaran, Dimuth Navaratna, Sandip Mondal.
      An exponentially growing global population has led to an increase in nutrient pollution in different aqueous bodies. Although different processes have successfully removed nutrients from wastewater on a large scale, a limited number of studies have been reported on efficiency, cost-effectiveness, and future potential of physical, chemical, and biological nutrient recovery methods to overcome the depletion of natural resources. Therefore, researchers need to understand current research trends by applying different approaches to investigate higher efficient nutrient recovery technologies. In this article, the research patterns and in-depth review of various nutrient recovery processes have been circumscribed with the application of bibliometric and attractive index (AAI) vs. activity index (AI) analysis. The performance, advantages, limitations, and future prospects of different nutrient recovery methods have also been addressed. More than 70% of study publications were published in the last decade in chemical and biological processes, which might be related to more rigorous effluent quality rules and increasing water pollution. The future prediction in the field of nutrient recovery has been predicted using S-curve analysis, and it was found that the number of publications in the saturated state in chemical methods was highest. However, the growth rate of the biological-based nutrient recovery methods is greater, which may be because of their huge research scope, cost-effectiveness, and easy operation methods. This study can assist researchers in understanding the current research scenario in nutrient recovery techniques and provide the research scope in nutrient recovery from wastewater in the future.

    Contribution of Turkey in Liver Transplant Research: A Scopus Database Search.
    Oruç Numan Gökçe, Sevil Alkan.
       OBJECTIVES: Liver transplantation is considered the most effective treatment modality for end-stage liver failure. The first deceased donor liver transplant in Turkey was performed by Haberal and colleagues in 1988; in 2019, a total of 1776 liver transplant procedures were performed in Turkey. While these are well-known and documented facts, the scientific output of publications on liver transplantation from Turkey is unknown. This study aimed to analyze the contribution of Turkey in liver transplant global research.
    MATERIALS AND METHODS: Publications from Turkey on liver transplantation were analyzed using the bibliometric study method. The following research parameters were analyzed: year of publication, institutions and authors, funding, themes, sample population, and methods. We used the Scopus database to research key words containing "liver" or "hepatic" and "transplantation" in the titles, abstracts, and key words. Among duplications or multiple results, only 1 publication was included in the study. Data were analyzed by quantitative and qualitative methods.
    RESULTS: We identified 45 763 publications on liver transplant. Most of the publications were in the field of medicine (93.48%). Turkey ranked fourteenth with 843 publications. The top productive affiliation was Başkent University, and the most productive author was Prof. Haberal.
    CONCLUSIONS: Among countries, Turkey had the most living donor liver transplants in 2019 and could serve as a model to European countries for donor shortages. Although the United States performs 5 times more liver transplants than Turkey, their publications rate was almost 22 times more. Combining a workload of performing research and publishing along with transplant surgery is together hard to master. Although Turkey has valuable experiences and has opened frontiers in transplantation, publications need to keep up with their hard work and innovations.

       BACKGROUND: Juvenile primary fibromyalgia syndrome (JPFS) is a chronic musculoskeletal pain syndrome that affects children and adolescents.
    METHODS: A VOSviewer-based bibliometric network analysis was performed by scanning the global literature on JPFS in the Web of Science (WOS) online database. The search string applied to identify the closest matching articles was "juvenile primary fibromyalgia syndrome (all field)".
    RESULTS: A total of 67 articles on JPFS were published from 1985 to March 2022, in the WOS. Regarding article types, 39 were research manuscripts, 16 reviews, 8 meeting abstracts, 2 letters, 1 book chapter, 1 correction, and 1 proceeding paper. The Quartile analysis demonstrated that 44% of papers were published in Q1, 37% in Q2, 8% in Q3, and 11% in Q4.
    CONCLUSIONS: Our analysis highlights that more efforts are warranted to increase the production of quality papers and enhance the connections between the various research groups. JFPS represents a research field still to be explored and which deserves greater investments to obtain quality scientific evidence.

    The application of resilience theory in urban development: a literature review.
    Li Kong, Xianzhong Mu, Guangwen Hu, Zheng Zhang.
      In the complex context of urbanization and climate change, how to improve the resilience of cities to deal with various uncertain and unpredictable threats is a new topic with both theoretical and practical challenges. In this paper, the researches on urban resilience are summarized using the bibliometric analysis combined with the visualization analysis. We provide a systematic and objective review of resilience applied to urban development focusing on its conceptual frameworks, research tendencies, and assessment methods. The analysis results demonstrate that an increasing attention has been given to urban resilience, especially in the field of climate change. The degree of research varies significantly in different countries, with the USA dominating in the number of publications, followed by the UK and China. Scholars' attention to urban resilience in different periods is closely related to the development background and disasters experienced by their countries, but there are also some commonalities. Meanwhile, the multi-dimensional research on urban resilience has been recognized by many scholars. Quantitative assessment tools such as simulation model and optimization model have been widely used to assess the level of urban resilience. Based on this, we put forward the future research trends in this field and provide a potential guide for future application of urban resilience.

    Four Decades of Randomized Clinical Trials Influencing Mortality in Critically Ill and Perioperative Patients.
    Carolina S Romero, Esther Romero, Nicolò Maimieri, Maria Popp, Cristiano Marchetti, Gaetano Lombardi, Alessandro Ortalda, Alberto Zangrillo, Giovanni Landoni.
       OBJECTIVES: Randomized clinical trials (RCTs) represent the highest level of scientific evidence. The aim of this review was to map and summarize the main characteristics and publication trends of RCTs with a statistically significant effect on mortality in critically ill and perioperative patients.
    DESIGN: A mapping review of RCTs published between January 1982 and January 2021. The authors searched PubMed/MEDLINE and EMBASE for RCTs reporting mortality data. A descriptive analysis was conducted, including general and methodologic information of all these RCTs with a statistically significant difference (p < 0.05) in mortality.
    MEASUREMENTS AND MAIN RESULTS: The authors identified 340 studies published in 115 journals from 42 countries. The most represented clinical areas were ventilatory support (n = 58, 17%) and hemodynamics (n = 56, 16%). A detrimental effect on survival was described in 47 (14%) RCTs. Denmark had the highest number of published trials per million inhabitants. A total of 40 (12%) RCTs were led by a female author. The intention-to-treat principle was applied overall in 60% of RCTs, though this percentage increased up to 75% when the study was published in journals with high impact factor.
    CONCLUSIONS: In the largest contemporary RCTs database of interventions significantly influencing mortality, the authors found an increase in scientific production. United States, China, France, Italy, and the United Kingdom contributed with 172 (51%) RCTs over 40 years. Only 20% of the studies were multinational collaborations, though this percentage increased over time. The presence of women as first authors was 1 out of 8 RCTs.

    Conflict of Interest Disclosure Among the Highest Earning Physicians Receiving Compensation From Vascular Device Companies.
    Fares Al-Khouja, Amanda Nyam, Brian Sheehan, Brittany Sullivan, Nii-Kabu Kabutey, Michael J Stamos, Alessio Pigazzi, Mehraneh D Jafari.
       OBJECTIVE: To characterize the association between payments made by vascular device companies to clinicians, and the conflict of interest (COI) declarations on relevant publications.
    SUMMARY BACKGROUND DATA: Close association between medical device companies and clinicians is essential in the advancement of surgical technology. When evaluating the efficacy of novel equipment, identification of these relationships can minimize the risk of bias in relevant studies.
    METHODS: Using the Open Payments Database (OPD), the 10 highest compensated clinicians from 10 vascular device companies were identified. In the population based bibliometric analysis, general payments, number of payments, h-index, and academic rank were identified. PubMed and Scopus were queried to identify author publications. Relevance to payment received and COI disclosures were identified for each article.
    RESULTS: The physicians identified earned $33,442,266.74 with a median of $92,500 in 2017. The authors published an average of 6.46+/-9.08 articles in 2018. Relevant COI was identified in 74%. In 50.5% of the relevant publications was a COI declared. The median h index of authors was 18+/-23. Community based physicians had a higher rate of COI disclosure (65.6%) compared to academic physicians (47.6%) (P = .008). Low h-index authors had a higher rate of COI declaration (71.4%) compared to high h-index (43.6%) (P = .001).
    CONCLUSION: A high degree of inconsistency was found between self-declared COI and relevant articles published by the highest compensated physicians. We propose a policy of full disclosure and the addition of a link to each author's OPD page on all publications to increase access to potential COI.

    The high scholarly value of grey literature before and during Covid-19.
    Kayvan Kousha, Mike Thelwall, Matthew Bickley.
      New academic knowledge in journal articles is partly built on peer reviewed research already published in journals or books. Academics can also draw from non-academic sources, such as the websites of organisations that publish credible information. This article investigates trends in the academic citing of this type of grey literature for 17 health, media, statistics, and large international organisations, with a focus on Covid-19. The results show substantial and steadily increasing numbers of citations to all 17 sites, with larger increases from 2019 to 2020. In 2020, Covid-19 citations to these websites were particularly common for news organisations, the WHO, and the UK Office for National Statistics, apparently for up-to-date information in the rapidly changing circumstances of the pandemic. Except for the UN, the most cited URLs of each organisation were not traditional report-like grey literature but were other types, such as news stories, data, statistics, and general guidance. The Covid-19 citations to most of these websites originated primarily from medical research, commonly for coronavirus data and statistics. Other fields extensively cited some of the non-health websites, as illustrated by social science (including psychology) studies often citing UNESCO. The results confirm that grey literature from major websites has become even more important within academia during the pandemic, providing up-to-date information from credible sources despite a lack of academic peer review. Researchers, reviewers, and editors should accept that it is reasonable to cite this information, when relevant, and evaluators should value academic work that supports these non-academic outputs.

    Association of International Editorial Staff With Published Articles From Low- and Middle-Income Countries.
    Gandolina Melhem, Chris A Rees, Bruno F Sunguya, Mohsin Ali, Anura Kurpad, Christopher P Duggan.
       Importance: The association between geographic diversity of medical journal editorial staff and publications reporting research conducted in low- and middle-income countries (LMICs) is unclear.
    Objective: To examine the association between having editorial staff members affiliated with LMICs and publishing research articles from LMICs in leading biomedical journals.
    Design, Setting, and Participants: This cross-sectional study included biomedical journals in fields representing the largest disease burden globally from January 1 to December 31, 2020. Websites of the 5 leading journals in general medicine, pediatrics, surgery, obstetrics and gynecology, cancer, cardiovascular diseases, infectious diseases, psychiatry, and nutrition were reviewed to obtain the country affiliations of editorial staff members. To determine article study countries, original research articles in each journal were reviewed through MEDLINE. Editorial staff country affiliations and study country locations were classified according to World Bank income brackets and regions.
    Exposure: Editorial staff country affiliation.
    Main Outcomes and Measures: Descriptive statistics of the proportion of editorial staff affiliated with each income bracket and region and Spearman rank correlation coefficients were used to assess the association between the proportion of editorial staff affiliated with LMICs and the proportion of published articles reporting work conducted in these countries.
    Results: There were 3819 editorial staff members in the 45 included journals: 3637 (95.2%) were affiliated with high-income countries, 140 (3.7%) with upper-middle-income countries, 37 (1.0%) with lower-middle-income countries, and 5 (0.1%) with low-income countries. All 48 editors-in-chief were affiliated with a high-income country. Editorial staff members were mostly affiliated with North American countries (n = 2120 [55.5%]) and European or Central Asian countries (n = 1256 [32.9%]). Of the 10 096 original research articles included in our analysis, 7857 (77.8%) reported research conducted in high-income countries, 1562 (15.5%) reported research conducted in upper-middle-income countries, 507 (5.0%) reported research conducted in lower-middle-income countries, and 170 (1.7%) reported research conducted in low-income countries. Greater editorial staff representation correlated moderately with more published articles reporting research conducted in LMICs (Spearman ρ = 0.51; 95% CI, 0.25-0.70; P < .001).
    Conclusions and Relevance: In this cross-sectional study, editorial staff in leading biomedical journals were largely composed of individuals affiliated with high-income countries in North America and Europe. A correlation was found between greater editorial staff representation and publication of research focused on LMICs, suggesting that the inclusion of editorial staff affiliated with LMICs may promote the publication of research conducted in those countries.

    Transfer of parasitology research to patents worldwide.
    Jose Antonio Garrido-Cardenas, Alfredo Alcayde, Francisco Manzano-Agugliaro, Concepcion M Mesa-Valle.
      Mankind has known about different parasitic diseases since ancient times. There is no doubt that parasites are the infectious agents that have caused the most deaths throughout history. But even today, parasitic diseases affect more than one billion people worldwide. In this paper, the relationship between articles published in the area of parasitology and international patents in this field from 1996 to 2019 was analyzed. For this purpose, Scopus has been used. This is a database developed by Elsevier, which, in addition to having numerous indexed journals and books, has developed SciVal, an analysis tool with which the publications that have been cited in the patents of the 5 largest patent offices in the world have been analyzed. The analysis has allowed us to study 2814 publications, to know their time trend, their Authors, Affiliations, and Countries, as well as the journals in which they have been published. Also, the topics and topic clusters related to parasitology that appear in publications cited in international patents have been known. Thus, the existence of six Topic Clusters that group 94% of all publications has been discovered. Of all of them, the Topic Cluster referring to malaria stands out above all others, with 968 articles (34% of the total), probably due to the fact that malaria continues to be, to this day, one of the great challenges for both industry and basic research throughout the world.

    Unveiling the Multitarget Anti-Alzheimer Drug Discovery Landscape: A Bibliometric Analysis.
    Anna Sampietro, F Javier Pérez-Areales, Paula Martínez, Elsa M Arce, Carles Galdeano, Diego Muñoz-Torrero.
      Multitarget anti-Alzheimer agents are the focus of very intensive research. Through a comprehensive bibliometric analysis of the publications in the period 1990-2020, we have identified trends and potential gaps that might guide future directions. We found that: (i) the number of publications boomed by 2011 and continued ascending in 2020; (ii) the linked-pharmacophore strategy was preferred over design approaches based on fusing or merging pharmacophores or privileged structures; (iii) a significant number of in vivo studies, mainly using the scopolamine-induced amnesia mouse model, have been performed, especially since 2017; (iv) China, Italy and Spain are the countries with the largest total number of publications on this topic, whereas Portugal, Spain and Italy are the countries in whose scientific communities this topic has generated greatest interest; (v) acetylcholinesterase, β-amyloid aggregation, oxidative stress, butyrylcholinesterase, and biometal chelation and the binary combinations thereof have been the most commonly pursued, while combinations based on other key targets, such as tau aggregation, glycogen synthase kinase-3β, NMDA receptors, and more than 70 other targets have been only marginally considered. These results might allow us to spot new design opportunities based on innovative target combinations to expand and diversify the repertoire of multitarget drug candidates and increase the likelihood of finding effective therapies for this devastating disease.

    Analysis of Development Trends of the Research Hotspots of Vitamin D in Children.
    Xuemei Luo, Feifeng Wu, Cheng Wang, Chuan Wen.
       Objective: Using multivariate statistics and social network analysis techniques, we present a realistic and intuitive visualization of the research hotspots and development trends of vitamin D in children.
    Methods: The Medical Subject Headings (MeSH) term "vitamin D" was used to search all the publications (the study subjects were 0-18 years old) included in PubMed by time period. The subject terms for each development stage were extracted, the high-frequency subject terms were extracted using the Bibliographic Items Co-occurrence Matrix Builder (BICOMB), and a core subject term co-occurrence matrix was established. The Netdraw function of Ucinet 6.0 software was used to complete the social network drawing of the core subject term co-occurrence matrix to form a co-word network diagram composed of core subject terms.
    Results: Prior to 1979, there were 890 papers with 1,899 core subject terms; from 2010 to 2020, there were 3,773 papers with 12,682 core subject terms. Before 1979, the research direction of vitamin D in children focused on vitamin D in the classical regulation of calcium and phosphorus metabolism. From 1980 to 1989, studies focused on vitamin D metabolites and therapeutic drugs such as "calcitriol" and "calcifediol." From 1990 to 1999, studies focused on "calcitriol" and its association with "psoriasis," "chronic renal failure," and "dermatological drugs." From 2000 to 2009, studies focused on "vitamin D" and "vitamin D deficiency." From 2010 to 2020, studies focused on "vitamin D3" and its association with "vitamins," "bone mineral density protectants," "asthma," "obesity," "pregnancy complications" and "fetal blood."
    Conclusion: Since 2010, the research direction of vitamin D in children has been growing rapidly, and the overall development trend is good. Studies extend from the study of the skeletal effect of vitamin D to the study of its extraskeletal effect and the investigation of mechanisms of its association with related diseases.

    Analysis of Research Directions on the Rehabilitation of Patients with Stroke and Diabetes Using Scientometric Methods.
    Ileana Pantea, Angela Repanovici, Maria Elena Cocuz.
      The multidisciplinary approach to the rehabilitation of patients with stroke and diabetes has been followed in this article by a review of the literature published in the Web of Science in the last ten years. A review of the literature was performed using scientometric methods. VOS Viewer software was used to determine the research directions in this area. Scientometric analysis has extracted relevant published scientific output that treats diabetes and stroke. Studies based on qualitative research and the conclusions of these studies were analyzed. The clusters with the keywords used in the title and abstract by the authors who published in the Web of Science were reviewed and research directions in the field were formulated. The proper care of diabetes and its numerous consequences, including stroke and its neurologic complications, necessitates the fast identification of research findings in various types of medicines and their efficacy when applied to various patient groups, such as diabetic patients, whose recovery after a stroke is similar to that of a nondiabetic patient following hemodynamic stabilization, although it takes longer and has poorer outcomes. The limitations of the study refer to the fact that the data reviewed are from the Web of Science only.

    Digital Innovation, Data Analytics, and Supply Chain Resiliency: A Bibliometric-based Systematic Literature Review.
    Anas Iftikhar, Imran Ali, Ahmad Arslan, Shlomo Tarba.
      In recent times, the literature has seen considerable growth in research at the intersection of digital innovation, data analytics, and supply chain resilience. While the number of studies on the topic has been burgeoning, due to the absence of a comprehensive literature review, it remains unclear what aspects of the subject have already been investigated and what are the avenues for impactful future research. Integrating bibliometric analysis with a systematic review approach, this paper offers the review of 262 articles at the nexus of innovative technologies, data analytics, and supply chain resiliency. The analysis uncovers the critical research clusters, the evolution of research over time, knowledge trajectories and methodological development in the area. Our thorough analysis enriches contemporary knowledge on the subject by consolidating the dispersed literature on the significance of innovative technologies, data analytics and supply chain resilience thereby recognizing major research clusters or domains and fruitful paths for future research. The review also helps improve practitioners' awareness of the recent research on the topic by recapping key findings of a large amount of literature in one place.

    The Impact of COVID-19 Pandemic on Scientific Research: an Upcoming New Wave?
    Nicola Cosentino, Giancarlo Marenzi, Mattia Chiesa.
      The coronavirus disease (COVID)-19 pandemic continues to have an impact on health care. A potential new wave can be foreseen concerning the impact of the pandemic on medical research and literature. We focused our attention on journals belonging to "Medicine, General and Internal" Clarivate™ category and "Q1" journal impact factor quartile. We found that since January 2020, 9621 papers regarding COVID-19 have been published in these journals. This occurred at the expense of non-COVID-19-related scientific papers as most journals did not increase the total number of their published articles. Thus, our analysis may outlook a new potential scientific wave related to COVID-19, in addition to the clinical ones, possibly delaying the improvement in the quality of care for other diseases in the next years.

    Academic Career Outcomes of Orthopedic Research and Education Foundation Resident Grant Recipients.
    Jason Silvestre, Regan K Burgess, Charles L Nelson, Terry L Thompson.
      The Orthopaedic Research and Education Foundation (OREF) awards Resident Research Grants to orthopaedic surgery residents. Outcomes are lacking for OREF resident grant recipients including academic career choice and scholarly productivity. This was a retrospective cohort study of OREF resident grant recipients (2012-2020). The percentage of OREF resident grant recipients selecting an academic career was compared with the percentage of academic orthopaedic surgeons in the United States via chi square test. Two hundred and seventy-six OREF resident grants were issued to 272 orthopaedic surgery residents at 73 programs. OREF resident grant recipients were predominantly male (79.0%) and Caucasian (70.2%). OREF resident grant recipients had greater women representation than the national cohort of orthopaedic surgery residents (21.0% vs 16.0%, p=0.030) with similar proportions of under-represented racial minorities (29.8% vs 27.2%, p=0.351). OREF resident grants consisted of clinical (69.6%) and basic/translational science (30.4%) research and awarded mostly for sports medicine (25.4%), trauma (18.8%), and adult reconstruction (15.9%) topics. The average h-index was 8.5 ± 9.2 resulting from 29.5 ± 51.2 manuscripts. The majority of OREF resident grant recipients selected an academic career, which was higher than a national benchmark of academic orthopaedic surgeons (63.8% vs 24.4%, p<0.001). Two OREF resident grant recipients transitioned to NIH research funding (0.7%). Multivariable logistical regression demonstrated two independent characteristics associated with pursuit of a future academic career: female sex (p=0.042) and higher h-index values (p=0.002). Procurement of OREF resident grants is associated with pursuit of an academic career. CLINICAL SIGNIFICANCE: There is great interest in fostering the next generation of orthopaedic surgeon scientists. Results from this study demonstrate the association between receipt of an OREF resident research grant and pursuit of a future career in academic orthopaedic surgery.

    Fourteen Crutches for Mediocrity. The logismoi that jeopardize good research and publication.
    Fernando Augusto Mardiros Herbella, Michael Gregory Sarr, Marco Giuseppe Patti.
      Publications are used widely as a measure of academic quality. Many investigators have difficulty publishing in this competitive field. After coming across a religious lecture on the "Fourteen Crutches for Mediocrity", our team adapted this approach to life to the science of publishing: (1) what is the problem of doing it?; (2) there are worse!; (3) everybody does it!; (4) why exaggerate?; (5) I will do it tomorrow!; (6) maybe if …; (7) it is not used anymore!; (8) be a cousin not a brother!; (9) I need to be thanked!; (10) don't eat your own head, let it be!; (11) I can't possibly accomplish it!; (12) I don't feel like doing it!; (13) I am fed up!; (14) I am not worthwhile! These crutches jeopardize good research and thoughtful learned publications.

      The value of biomedical research-a $1.7 trillion annual investment-is ultimately determined by its downstream, real-world impact, whose predictability from simple citation metrics remains unquantified. Here we sought to determine the comparative predictability of future real-world translation-as indexed by inclusion in patents, guidelines, or policy documents-from complex models of title/abstract-level content versus citations and metadata alone. We quantify predictive performance out of sample, ahead of time, across major domains, using the entire corpus of biomedical research captured by Microsoft Academic Graph from 1990-2019, encompassing 43.3 million papers. We show that citations are only moderately predictive of translational impact. In contrast, high-dimensional models of titles, abstracts, and metadata exhibit high fidelity (area under the receiver operating curve [AUROC] > 0.9), generalize across time and domain, and transfer to recognizing papers of Nobel laureates. We argue that content-based impact models are superior to conventional, citation-based measures and sustain a stronger evidence-based claim to the objective measurement of translational potential.

    State-of-the-art on analytic hierarchy process in the last 40 years: Literature review based on Latent Dirichlet Allocation topic modelling.
    Peter Madzík, Lukáš Falát.
      Although there are several articles that have carried out a systematic literature review of the analytical hierarchy process (AHP), many of them work with a limited number of analyzed documents. This article presents a computer-aided systematic literature review of articles related to AHP. The objectives are: (i) to identify AHP usage and research impact in different subject areas; (ii) to identify trends in the popularity of the AHP from the first introduction of the method in 1980 to the present; (iii) to identify the most common topics related to AHP and topic development over time. We process 35,430 documents related to AHP, published between 1980 and 2021, retrieved from the Scopus database. We provide detailed statistics about research interest, research impact in particular subject areas over the analyzed time period. We use Latent Dirichlet Allocation (LDA) using Gibbs sampling to perform topic modeling based on the corpus of abstracts. We identify nine topics related to AHP: Ecology & Ecosystems; Multi-criteria decision-making; Production and performance management; Sustainable development; Computer network, optimization and algorithms; Service quality; Fuzzy logic; Systematic evaluation; Risk assessment. We also present the individual topics trends over time and point out the possible future direction of AHP.

    Discovering trends and hotspots of biosafety and biosecurity research via machine learning.
    Renchu Guan, Haoyu Pang, Yanchun Liang, Zhongjun Shao, Xin Gao, Dong Xu, Xiaoyue Feng.
      Coronavirus disease 2019 (COVID-19) has infected hundreds of millions of people and killed millions of them. As an RNA virus, COVID-19 is more susceptible to variation than other viruses. Many problems involved in this epidemic have made biosafety and biosecurity (hereafter collectively referred to as 'biosafety') a popular and timely topic globally. Biosafety research covers a broad and diverse range of topics, and it is important to quickly identify hotspots and trends in biosafety research through big data analysis. However, the data-driven literature on biosafety research discovery is quite scant. We developed a novel topic model based on latent Dirichlet allocation, affinity propagation clustering and the PageRank algorithm (LDAPR) to extract knowledge from biosafety research publications from 2011 to 2020. Then, we conducted hotspot and trend analysis with LDAPR and carried out further studies, including annual hot topic extraction, a 10-year keyword evolution trend analysis, topic map construction, hot region discovery and fine-grained correlation analysis of interdisciplinary research topic trends. These analyses revealed valuable information that can guide epidemic prevention work: (1) the research enthusiasm over a certain infectious disease not only is related to its epidemic characteristics but also is affected by the progress of research on other diseases, and (2) infectious diseases are not only strongly related to their corresponding microorganisms but also potentially related to other specific microorganisms. The detailed experimental results and our code are available at https://github.com/KEAML-JLU/Biosafety-analysis.

    A bibliometric and thematic approach to agriculture 4.0.
    Diego Durante Mühl, Letícia de Oliveira.
      Researchers are developing digital solutions for agriculture. Humanity has perfected agriculture throughout history because this activity is fundamental to our existence. The agricultural sector is currently incorporating new technologies from other areas. This phenomenon is agriculture 4.0. However, a challenge to research is the integration of technologies from different knowledge fields, and this has caused theoretical and practical difficulties. Thus, our purpose with this study has been to understand the core agriculture 4.0 research themes. We have used a bibliometric analysis, and guided the data collection by the PRISMA protocol. VosViewer and Bibliometrix software generated the results. We found two main research fronts, one focussed on agriculture 4.0 development, and another on the impacts of agriculture 4.0, which may be positive or negative. We found 21 main keywords or topics researched in agriculture 4.0 related to these research fronts. These themes are within five different axes. We managed to establish a good understanding of the topics around agriculture 4.0. Future studies could focus on the responsible development of digital solutions for agriculture. This is because the social, environmental, and economic impacts of these new solutions may be positive or negative. We conclude that digital agriculture is the node technologies integration for the automation of agricultural activities.
