    Developments in congenital scoliosis and related research from 1992 to 2021: a thirty-year bibliometric analysis.
    Ziyang Liu, Yunzhong Cheng, Yong Hai, Yuxiang Chen, Tie Liu.
       BACKGROUND: Many studies, mainly original articles and reviews, have been published on congenital scoliosis (CS), but there is a lack of bibliometric analyses. This study aimed to systematically analyze the developments and focuses in CS and related research fields.
    METHODS: Data were retrieved from the Web of Science Core Collection database, and the top 100 most-cited studies were analyzed emphatically. The Web of Science's Results Analysis and Citation Report was used to analyze different aspects of the published literature. CiteSpace was used to analyze the cooperation network, reference co-citation, burst keywords, and burst citations.
    RESULTS: The final analysis included 749 studies. The field of CS and related research has been rapidly expanding. Several journals have published relevant studies and most-cited studies on this topic. Cooperation was noted among authors, institutions, and countries/regions in multiple instances. "Surgical techniques" (hemivertebra resection/posterior vertebral column resection/vertical expandable prosthetic titanium rib/double approach/grade 4 osteotomy) was one of the most common research focuses. In addition, research on genetics and molecular biology related to CS has become an emerging trend due to advances in basic science.
    CONCLUSIONS: Over time, research on CS and in related fields has gained greater attention and has been expanding continuously, showing a trend toward globalization. We recommend that researchers focus on the progress of surgical techniques, advances in molecular biology and genetics, and characteristics of CS. The top clusters, most-cited articles, and references with the strongest burst citations should be studied further.

    Research status and hotspots of cesarean scar pregnancy from 2001 to 2020: a bibliometric analysis.
    Pin Qiu, Xinyi Lin, An Li, Gaopi Deng.
       BACKGROUND: Due to the significant increase in cesarean section rates worldwide, cesarean scar pregnancy (CSP) has attracted extensive attention. This study aimed to investigate the global research status and developmental directions of CSP to discern promising research hotspots by means of bibliometrics and visualized analyses.
    METHODS: The English CSP-related literature from 2001 to 2020 was retrieved from The Web of Science Core Collection (WOSCC) database. Microsoft Excel 2019 was used to analyze the years, countries, institutions, journals, authors, citations, H indices, titles, abstracts, and keywords of related literature, and VOSviewer software was used to visualize developmental directions and promising hotspots in CSP.
    RESULTS: The study included 1,186 articles in total. The number of CSP articles has presented an overall increasing trend over the last two decades. China has the maximum number of publications, but America's H-index is higher than that of China, with the average number of citations per item ranking fourth. The Journal of Obstetrics and Gynaecology Research published the most on the subject, while Zhejiang University from China published the largest number of articles; Jurkovic D, Timor-Tritsch IE, and Monteagudo A have achieved considerable progress in the CSP domain. There are 5 clusters that the current research orientation can fall into: "selection of the delivery mode with a scarred uterus after cesarean section", "risk factors", "diagnosis", "treatment" and "related basic and clinical experiments". High-intensity focused ultrasound (HIFU) and the formulation of consensus guidelines are the focus of the current research.
    CONCLUSIONS: The analysis of global trends shows that CSP research is being actively studied and that the number of published studies is continuously increasing. According to the comprehensive quality and quantity of the literature, the United States maintains a leading position in CSP research. In recent years, the research directions have mainly focused on "diagnosis", "treatment" and "risk factors", while HIFU and the formulation of consensus guidelines may become research hotspots in the field of CSP.

Bibliometrics could assist scholars in understanding the scope of research topics better, identifying research focuses and key literature, and analyzing the development and trend of analgesics in the treatment of postoperative pain following orthopedic surgery.
    Methods: Literature data were retrieved from the Science Citation Index Expanded (SCI-E) of Web of Science (WOS) Core collection database. The articles from 1992 to December 2021 on analgesics in the treatment of postoperative pain following orthopedic surgery were recruited. The citation reports including the publication numbers, h-index, total citations, and average citations in terms of authors, organizations, and countries were obtained. Top 20 research directions, funds, and journals with the most publications were charted. The co-authorship relations in the analysis units of authors, organizations, and countries were analyzed by the online bibliometric tool and VOSviewer software. The author's keywords co-occurrence overlay map was visualized by the VOSviewer software.
    Results: A total of 406 articles were retrieved from 1992 to December 4th, 2021, with 11,655 times cited, average citations of 28.57 per item, and an h-index of 55. The most high-yield publication year, authors, organizations, countries, research directions, funds, and journals were 2020 (n = 887), Ilfeld BM from University of California San Diego (n = 7), University of California System (n = 21), the USA (n = 178), Anesthesiology (n = 161), National Institutes of Health (NIH), USA, and United States Department of Health Human Services (n = 12), and Anesthesia and Analgesia (n = 29), respectively. Similarly, co-authoring analysis of publications regarding on different analgesics showed that the authors and countries with the most co-authorship strength were Carr Daniel B (total link strength = 6) and the USA (total link strength = 30), respectively. The highest occurrence keywords were "postoperative pain" with 135 occurrences (total link strength = 784). The future research hotspots might be "acute pain," "outcomes," "oxycodone," "total hip," "replacement," and "United States."
    Conclusion: Analgesics in the treatment of postoperative pain following orthopedic surgery can be observed in this study by employing the online bibliometric tool and VOSviewer software, which established the relationship between the units of analysis. It can provide a meaningful resource with detailed information for orthopedic surgeons who would like to understand the trend in this field better.

      Background: The number of publications on SMAD7 in the field of oncology is increasing rapidly with an upward tendency. In most cases, the mechanisms of carcinogenesis usually relate to disorders of signaling activity. Considering the crucial role of SMAD7 in the crosstalk of multiple signaling pathways, it is necessary to clarify and define the dominant research topics, core authors, and their cumulative research contributions, as well as the cooperative relationships among documents or researchers. Methods: Altogether, 3477 documents were retrieved from the Web of Science Core Collection with the following criteria: TS= (SMAD7 OR SMAD7-protein OR Small-Mothers-Against-Decapentaplegic-7) refined by WEB OF SCIENCE CATEGORY (ONCOLOGY) AND [excluding] PUBLICATION YEARS (2021) AND DOCUMENT TYPES (ARTICLE OR REVIEW) AND LANGUAGES (ENGLISH) AND WEB OF SCIENCE INDEX (Web of Science Core Collection, SCI), and the timespan of 2011-2020. Bibliometric visualization analysis was conducted with CiteSpace and VOSviewer. Results: The number of documents grew each year. A total of 2703 articles and 774 reviews were identified from 86 countries/regions, 3524 organizations, 928 journals, and 19,745 authors. China was the most prolific country, with 1881 documents. Contributions from China, the United States, and Germany were the most substantial. The most influential author was Lan Huiyao at The Chinese University of Hong Kong, with 24 publications and 2348 total citations. The bibliometric analysis showed that multilateral cooperation among diverse institutions or investigators was beneficial to high-quality outputs. The keyword "PPAR-gamma" exhibited the strongest burst in recent years, suggesting a potent research focus in the future. Conclusion: Research on SMAD7 in oncology is continuously developing. Bibliometrics is an interesting tool to present the characteristics of publication years, main authors, and productive organizations in a visualized way. It is worth mentioning that a prospective focus might be the specific mechanism of the interaction of PPAR-gamma with SMAD7 in oncology. In all, bibliometric analysis provides an overview and identifies potential research trends for further studies in this academic field.

    Peiling Gan, Wentao Fan, Hailong Zhang, Chunyu Zhong, Huifang Xia, Muhan Lü, Xian Zhou, Xiaowei Tang.
       Background: Because the number of published literatures with a focus on Barrett's esophagus (BE) that researchers must be familiar with has quickly increased in recent years, the significance of selective searching and summarization of bibliometrics is also increasing. It is, thus, very important to find a method that can quickly and effectively search the most influential medical science articles. Therefore, the objective of this study was to use bibliometric analysis to assess and characterize the most influential articles involving BE research.
    Methods: Publications on BE research were retrieved from the Web of Science Core Collection using the term "Barrett's esophagus." Microsoft Excel 2016 and VOSviewer were used to further analyzed each article's citation number, title, journal, country, organization, category, and authorship.
    Results: On 14 June 2020, 5,389 records of BE research published until 2020 were retrieved. The citation number of the top 100 most-cited articles ranged from 208 to 824. Gastroenterology published 29 articles, which accounted for the largest number of top 100 articles (29%); however, among the top 500 most-cited articles, the American Journal of Gastroenterology published the largest number. Of the top-cited articles, the USA was by far the leading country in BE research and contributed most of the articles (n = 72). Among the academic institutions that produced the top 100 most-cited articles, the University of Washington (n = 12) was dominant. Sharma Prateek (n = 6) authored the largest number of most-cited articles. The USA contributed the most articles per year, and the time trend of the number of top 500 articles increased by 38-fold between 1987 and 2000. "Adenocarcinoma," "high-grade dysplasia," "cancer," "diagnosis," and "dysplasia" were the most influential keywords.
    Conclusions: This study not only presents a historical perspective but also facilitated the recognition of the significant advances in this area by researchers. Furthermore, the current study serves as a guide in decision clinical practice decision-making and provides a valuable reference for further research.

    A Musbahi, C B Rao, A Immanuel.
       INTRODUCTION: Bibliometric analyses are a method of evaluating the quality of research output in a certain domain. Robotic surgery has made vast leaps during the past 20 years and this paper aimed to assess some of the main areas of research using this method.
    METHODS: A search was undertaken for documents published between 2001 and 2021 from the World of Science database, using the keywords 'robotic surgery', 'robotic assisted surgery' and 'robotic-assisted surgery. Results were compared using numerous bibliometric methodologies, and stratified by source-specific metrics, author-specific metrics and country-specific metrics.
    RESULTS: The search yielded 3839 documents, from 879 different sources. Only 2% of sources were found to be within Bradford's Zone 1 of research and the most relevant sources were from the field of urology. The Journal of Urology and Surgical Endoscopy and other Techniques ranked highly among metrics such as H, G, M index and total citations. The top-rated authors had a H index of 15 in the field of robotic surgery and the total citations reached a peak at 1342. The USA, Japan and Italy were the most productive nations and increased collaborative research is leading to a greater number of multiple-centre publications.
    CONCLUSION: Research into robotic surgery is still in its infancy with further reviews of the literature and greater output through large randomised controlled trials in multiple centres through collaborative research needed.

    A Bibliometric Analysis of the Literature on Norovirus Disease from 1991-2021.
    Ropo E Ogunsakin, Oluwakemi Ebenezer, Themba G Ginindza.
      Norovirus (NoV) is one of the oldest recognized diseases and the leading causal pathogen for acute gastroenteritis (AGE) worldwide. Though numerous studies have been reported on NoV disease, limited research has explored the publication trends in this area. As a result, the objective of this work was to fill the void by conducting a bibliometric study in publication trends on NoV studies as well as discovering the hotspots. The Web of Science central assemblage database was hunted for publications from 1991 to 2021 with "norovirus" in the heading. Microsoft Excel 2016, VOSviewer, R Bibliometrix, and Biblioshiny packages were deployed for the statistical analysis of published research articles. A total of 6021 published documents were identified in the Web of Science database for this thirty-year study period (1991-2021). The analyses disclosed that the Journal of Medical Virology was the leading journal in publications on norovirus studies with a total of 215 published articles, the Journal of Virology was the most cited document with 11,185 total citations. The United States of America (USA) has the most significant productivity in norovirus publications and is the leading country with the highest international collaboration. Analysis of top germane authors discovered that X. Jiang (135) and J. Vinje (119) were the two top relevant authors of norovirus publications. The commonly recognized funders were US and EU-based, with the US emerging as a top funder. This study reveals trends in scientific findings and academic collaborations and serves as a leading-edge model to reveal trends in global research in the field of norovirus research. This study points out the progress status and trends on NoV research. It can help researchers in the medical profession obtain a comprehensive understanding of the state of the art of NoV. It also has reference values for the research and application of the NoV visualization methods. Further, the research map on AGE obtained by our analysis is expected to help researchers efficiently and effectively explore the NoV field.

    Characteristics from the 100 most influential articles on carotid stenosis.
    Ji Woong Hwang, Heungman Jun.
       BACKGROUND: There are three main competing treatment modalities for carotid artery stenosis (CS), i.e., carotid endarterectomy (CEA), carotid artery angioplasty/stenting (CAS), and medical treatment. In this study, we analyzed the performance and trends of CS research through bibliometric analysis.
    METHODS: We searched the Thomson Reuters Web of Science citation indexing database. The key words used in the search were "carotid artery" and "carotid stenosis". The top 100 most cited manuscripts (T100) were analyzed based on title, author, institution, country of origin, year of publication, and topic.
    RESULTS: The T100 were published between 1990 and 2016. The Stroke published the most manuscripts (n=22) and the New England Journal of Medicine was the most cited (n=15,113). The United States had the greatest number of publications (n=43), and the University of Oxford was the institution with the most publications (n=7). Peter M. Rothwell was the corresponding author with the most publications (n=10). The main topics were in the following categories: CEA (n=22), medication (n=11), CAS (n=9), diagnosis (n=44), and CEA vs. CAS (n=14).
    CONCLUSIONS: This bibliometric analysis of CS research provides insight into publication trends and perspective on the treatment of CS.

    Naime Meric Konar, Serkan Karaismailoglu, Eda Karaismailoglu.
       BACKGROUND: Personalized medicine (PM), as a rapidly growing research area, provides treatments, practices, interventions being adapted to an individual patient based on his own risk of disease. This study aims to analyze the productivity of countries, institutions, and authors in this field, to determine the existing research trends worldwide, and to forecast future research activity for specific countries.
    METHODS: Documents published between 2000 and 2020 were retrieved from the Web of Science (WoS) database. Bibliometric analysis was performed to assess the outputs, correlation analysis was applied to analyze the relationship between Gross Domestic Product per capita (GDP-PP) and the number of publications, extrapolation method was used for predicting the future productivity trends for certain countries.
    RESULTS: A total of 7772 documents were published globally on PM between 2000 and 2020. The most productive country, journal, institution are USA, Personalized Medicine, and Harvard Medical School, respectively. The USA is also first in line in terms of total citations. Netherlands, Denmark, and the USA are listed at the top in terms of the total number of papers and citations, after adjusting for GDP-PP and population size. Also, as predictions suggest, the USA will maintain its predominant role in the PM field in the next five years.
    CONCLUSIONS: Owing to its both interdisciplinary and multidisciplinary nature, PM bestows researchers' numerous sources to benefit and enables them a field that they can be productive of for the future. Therefore, this field is expected to progress and be the lead area in medicine in the upcoming years.

       Background: Atrophic gastritis (AG), which is characterized by a decreased number or disappearance of the glandular structures and secretory dysfunction, is linked to chronically inflamed stomach. It has been estimated that the annual incidence of gastric cancer (GC) is 0.1% for patients with AG. Early eradication of Helicobacter pylori (H. pylori) can reduce the risk of GC development. Additionally, the follow-up and management of AG are necessary to prevent GC. Exploring novel methods of the automatized analysis of data for apprehending knowledge in any medical field is encouraged, especially when a body of literature suggests the necessity of doing so. Accordingly, herein, we aim to systematically review the current foci and status of AG research using bibliometric analysis.
    Methods: Articles and reviews related to AG published from 2011 to 2021 in the Web of Science Core Collection were retrieved. Microsoft Office Excel 2019 and GraphPad Prism were used to show the annual number of publications and scientific productivity of authors through time. CiteSpace and VOSviewer were used to generate network maps about the collaborations among countries, institutions, and authors as well as reveal hotspots of AG research. The relationships among the author's keywords, cited references, and the top authors were summarized by a Sankey plot (three-fields plot).
    Results: A total of 1,432 publications were included in the present study. China remained the most productive country, with the highest number of publications (377, 26.32%). Vanderbilt University contributed the most publications of any single institution (56, 3.91%). James R Goldenring was the most active and influential scholar, with the highest number of publications and greatest centrality. The most prolific journal in this field was World Journal of Gastroenterology (62, 4.32%). Gastroenterology (997, 69.62%) was the most co-cited journal. Exploring the origin of gastric metaplasia, especially spasmolytic polypeptide-expressing metaplasia (SPEM) was a major topic in AG research.
    Conclusions: This bibliometric study provides a comprehensive analysis of the scientific progress of AG over the past decade. Metaplasia is a hot topic and could be a promising area of research in the coming years.

    Bibliometric Analysis of Global Research Productivity on Vitamin D and Bone Metabolism (2001-2020): Learn from the Past to Plan Future.
    Ahmad Azam Malik, Mukhtiar Baig, Nadeem Shafique Butt, Muhammad Imran, Sami Hamdan Alzahrani, Zohair Jamil Gazzaz.
      Vitamin D has long been known for preserving bone and non-skeletal health. Despite its magnitude of impact, scarce literature has explored the evolution of the relevant published literature. This study aimed at evaluating the trends and performance of Vitamin D and bone metabolism-related publications (2001-2020). All pertinent English language 16,887 articles were searched and extracted from the Web of Science (WoS) database and "R-Bibliometrix" was used for comprehensive analysis. Around 60,149 authors contributed from 114 countries, showing the USA on top with >1/4th of all articles, followed by Japan, China, and the United Kingdom. For authors, Cooper C, Dawson-Hughes B, and Holick MF were found to have written the most articles, citations and highest h-index, respectively. Corresponding authors from the top 20 countries collectively were responsible for around 84% of the articles. Among 2735 sources, Osteoporosis International (632), Journal of Bone and Mineral Research (569), and Bone (448) were foremost. Most prominent sources showed recent declining contributions. The increasing trend of publications with a higher spike from 2008 to 2014, followed by a gradual increase till 2017, was observed. Leading countries, affiliations, and authors showed collaborative publications and were mostly from developed countries with limited contributions, particularly from low- and middle-income countries.

    Siyu Hu, Xi Wang, Yucong Ma, Hang Cheng.
       Background: Coronavirus disease 2019 (COVID-19) emerged in 2019 and has since caused a global pandemic. Since its emergence, COVID-19 has hugely impacted healthcare, including pediatrics. This study aimed to explore the current status and hotspots of pediatric COVID-19 research using bibliometric analysis.
    Methods: The Institute for Scientific Information Web of Science core collection database was searched for articles on pediatric COVID-19 to identify original articles that met the criteria. The retrieval period ranged from the creation of the database to September 20, 2021. A total of 3,561 original articles written in English were selected to obtain data, such as author names, titles, source publications, number of citations, author affiliations, and countries where the studies were conducted. Microsoft Excel (Microsoft, Redmond, WA) was used to create charts related to countries, authors, and institutions. VOSviewer (Center for Science and Technology Studies, Leiden, The Netherlands) was used to create visual network diagrams of keyword, author, and country co-occurrence.
    Results: We screened 3,561 publications with a total citation frequency of 30,528. The United States had the most published articles (1188 articles) and contributed the most with author co-occurrences. The author with the most published articles was Villani from the University of Padua, Italy. He also contributed the most co-authored articles. The most productive institution was Huazhong University of Science and Technology in China. The institution with the most frequently cited published articles was Shanghai Jiao Tong University in China. The United States cooperated most with other countries. Research hotspots were divided into two clusters: social research and clinical research. Besides COVID-19 and children, the most frequent keywords were pandemic (251 times), mental health (187 times), health (172 times), impact (148 times), and multisystem inflammatory syndrome in children (MIS-C) (144 times).
    Conclusion: Pediatric COVID-19 has attracted considerable attention worldwide, leading to a considerable number of articles published over the past 2 years. The United States, China, and Italy have leading roles in pediatric COVID-19 research. The new research hotspot is gradually shifting from COVID-19 and its related clinical studies to studies of its psychological and social impacts on children.

    Research Landscape of Artificial Intelligence and e-Learning: A Bibliometric Research.
    Kan Jia, Penghui Wang, Yang Li, Zezhou Chen, Xinyue Jiang, Chien-Liang Lin, Tachia Chin.
      While an increasing number of organizations have introduced artificial intelligence as an important facilitating tool for learning online, the application of artificial intelligence in e-learning has become a hot topic for research in recent years. Over the past few decades, the importance of online learning has also been a concern in many fields, such as technological education, STEAM, AR/VR apps, online learning, amongst others. To effectively explore research trends in this area, the current state of online learning should be understood. Systematic bibliometric analysis can address this problem by providing information on publishing trends and their relevance in various topics. In this study, the literary application of artificial intelligence combined with online learning from 2010 to 2021 was analyzed. In total, 64 articles were collected to analyze the most productive countries, universities, authors, journals and publications in the field of artificial intelligence combined with online learning using VOSviewer through WOS data collection. In addition, the mapping of co-citation and co-occurrence was explored by analyzing a knowledge map. The main objective of this study is to provide an overview of the trends and pathways in artificial intelligence and online learning to help researchers understand global trends and future research directions.

    Priority of Gender and Racial Disparity in Neurology Journals: A Bibliometric Analysis, 2016-2021.
    Sumayya Mohammed, Javed Siddiqi.
       INTRODUCTION: Medicine and the field of neurology are not immune to gender and racial disparities present more broadly in society. Even within academia there remains a persistent lack of representation of women and racial minorities, but with the recent spotlight on discrimination it is more necessary than ever that prevailing disparities are acknowledged by medical journals and reflected in their publication priorities. This bibliometric study assesses whether social justice trends have influenced the number of articles published that discuss gender and racial disparity in the past 5 years within the top three leading neurological journals. Our assumption is that any trend towards more publications related to gender and racial disparities are reflective of the publication priorities of, and thus the perceived relevance to, the editorial boards of the chosen journals.
    METHODS: Using key word search of "gender," "race," and "disparity" in the title or context of published papers, the archives of Lancet Neurology, Nature Reviews Neurology, and Alzheimer's & Dementia were reviewed.
    RESULTS: The results indicated that although there was a slight overall increase in coverage of the aforementioned topics, it was negligible compared to the broad impact of current social justice movements.
    CONCLUSION: Our data suggest an inadequate publication priority for scholarly work on gender and racial disparity in the chosen journals, over the latest 5 years reviewed.

    Ahmed Ben Abdelaziz, Sarra Melki, Donia Ben Hassine, Sarra Nouira, Dhekra Chebil, Asma Ben Abdelaziz, Mohamed Azzaza.
       OBJECTIVES: Describe the 2020 report of the ARWU "Academic Ranking World Universities" classification and identify, accordingly, the roadmap of academic excellence, particularly in the countries of the Greater Maghreb.
    METHODS: This is an in-depth reading of the 2020 results of the ARWU bibliometric platform (launched in 2003) from top 1000 world-class universities. Six criteria were used in this ranking: 1. Alumni (10%): students who received Nobel / Fields prizes; 2. Award (15%): professors who have won the Nobel / Fields prizes; 3. HiCi (20%): Most cited scientists; 4. PUB (20%): number of publications 5. TOP (20%): proportion of publications in the most influential periodicals; 6. PCP (10%): Per Capita Performance.
    RESULTS: The 2020 ARWU ranking was characterized by the domination of the "Top 10" ranking by the United States, particularly the "Harvard University", the Asian boom of 55% of the "Top 1000" ranking (Chinese universities evolved from 16 in 2004 to 81 in 2020 in the "Top 500" list) and finally an African incubation of academic excellence, manifested by the selection of nine South African institutions (including the "University of Cape Town ", world rank between 201-300), and the re-entry for the first time of a Maghreb university in the" Top 1000 "list, Tunis El Manar (rank between 901-1000), with the following scores: N&S: 1 , 4; Pub: 26.1 and PCP: 10.3, for a total score of 37.8 points.
    CONCLUSION: This report proves once again, the promising academic perspectives of Asia and Africa in the inclusion of the "Top 1000" list of the ARWU ranking. The roadmap for academic excellence would thus be based on the triad of centering scientific publications, in prestigious journals and by national author networks.

    ShaoPeng Che, Pim Kamphuis, Shunan Zhang, Xiangying Zhao, Jang Hyun Kim.
      This study aims to understand the research status and development trend of crisis and risk communication research (CRCR) through a visual analysis in CiteSpace, thereby providing a more comprehensive perspective for future research agenda. First, we retrieved published papers from Web of Science (1986-2020) and Scopus (1979-2020) with a title search. Subsequently, we analyzed the main research strengths and main topics of CRCR from two dimensions: co-authorship network and co-citation network. We conducted an in-depth co-citation network analysis from four perspectives: cluster analysis, high co-cited literature analysis, burst analysis, and turning points analysis. These results revealed the main research topics in the CRCR field, the most eye-catching research literature, the emerging research hotspots in each period, and the turning points of the overall development. Finally, we suggested further research directions for future avenues.

    Jose-Manuel Ramos-Rincon, Irene Monjas-Canovas, Javier Abarca-Olivas, Juan-Ramón Gras-Albert, Isabel Bellinchón-Romero, Gregorio Gonzalez-Alcaide.
      Objective In this study, we aimed to analyze research activity on cerebrospinal fluid (CSF) leaks in general and CSF rhinorrhea and otorrhea in particular and to identify the main topic clusters in these areas. Methods We identified all relevant documents, using the medical subject heading (MeSH) term "Cerebrospinal Fluid Leak", that are indexed in the MEDLINE database between 1945 and 2018. We performed a descriptive bibliometric analysis and analyses of networks and research clusters in order to identify the main topic areas of research. Results From 1945 to 2018, a total of 4,130 records were published with the term CSF leak, including 2,821 documents (68.1%) with the term CSF rhinorrhea and 1,040 documents (25.8%) with CSF otorrhea. The number of documents published increased from 10 in 1945-49 to 642 in 2010-14. Articles represented the dominant document type (86.8% of the documents analyzed), while case reports were the main type of study (37.4%). In terms of geographical distribution, researchers from the USA led in the number of signatures (39.1%), followed by those from the UK (7.5%). The most active areas of research in the field were "Postoperative Complications," "Tomography, X-Ray Computed," and "Magnetic Resonance Imaging." The terms "Adults," "Young Adult," and "Middle-Aged" were most common in CSF rhinorrhea research; and the terms "Infant," "Child, Preschool," "Child," and "Adolescent" were more common in CSF otorrhea. Conclusions Based on our findings, articles and case reports related to "Surgery" and "Postoperative Complications" associated with the diagnosis are the main topics of study, highlighting the importance of this document type in advancing knowledge in the field.

    Insights Into the Research Status of Neuromedin U: A Bibliometric and Visual Analysis From 1987 to 2021.
    Xueping Qi, Peidong Liu, Yanjie Wang, Jinmei Xue, Yunfang An, Changqing Zhao.
      Neuromedin U (NMU) is a regulatory peptide that is widely distributed throughout the body and performs a variety of physiological functions through its corresponding receptors. In recent years, NMU has become the focus of attention in various fields of research as its diverse and essential functions have gradually been elucidated. However, there have been no bibliometrics studies on the development trend and knowledge structure of NMU research. Therefore, in this study, we used VOSviewer software to statistically analyze scientific data from articles related to NMU to track the developmental footprint of this research field, including relevant countries, institutions, authors, and keywords. We retrieved a total of 338 papers related to NMU, written by 1,661 authors from 438 organizations of 41 countries that were published in 332 journals. The first study on NMU was reported by a group in Japan in 1985. Subsequently, nine articles on NMU were published from 1987 to 2006. A small leap in this field could be detected in 2009, with 30 articles published worldwide. Among the various countries in which this research has been performed, Japan and the United States have made the most outstanding contributions. Miyazato M, Kangawa K, and Mori K from the Department of Biochemistry, National Retrain and Cardiovascular Center Research Institute in Japan were the most productive authors who have the highest number of citations. Keyword analysis showed six clusters: central-nervous-system, homeostasis, energy metabolism, cancer, immune inflammation, and food intake. The three most highly cited articles were associated with inflammation. Overall, this study demonstrates the research trends and future directions of NMU, providing an objective description of the contributions in this field along with reference value for future research.

    Environmental Toxicants and Preterm Birth: A Bibliometric Analysis of Research Trends and Output.
    Manuel S Vidal, Ramkumar Menon, Gracia Fe B Yu, Melissa D Amosco.
      Preterm birth remains a problem globally, as multiple factors contribute to its etiology and pathogenesis. One such factor is the exposure to environmental toxicants, in which recent literature has described contributory roles in disease progression. This study aims to show research trends and collaborations in papers related to environmental toxicants and preterm birth through a bibliometric analysis to determine hot spots for research as well as to identify already established themes that can point to policy making and development. Using the Scopus database, we were able to identify 956 original research articles from 72 countries between 1955 and 2021; bibliographic information was exported, analyzed, and visualized using Bibliometrix and VOSviewer. There was an annual growth of research and reporting in this area, which significantly increased within the last two decades. The top countries that have published on this topic include the USA (n = 343), China (n = 103), and Australia (n = 43), with strong international collaboration in reports from China. Top journals for publication include Environmental Research (n = 53), Environmental Health Perspectives (n = 47), and Environment International (n = 46). Previous literature focused on establishing toxicants that are significantly associated with preterm birth, with current research focusing on molecular mechanisms of environmental toxicants. Overall, our bibliometric analysis gives a scoping view of the existing research landscape in terms of environmental health and preterm birth.

    Steroid Treatment in Macular Edema: A Bibliometric Study and Visualization Analysis.
    Yu Lin, Xiang Ren, Danian Chen.
      The use of steroids to treat macular edema (ME) is a research hotspot in ophthalmology. We utilized CiteSpace and VOSviewer software to evaluate the Web of Science Core Collection publications and to build visualizing maps to describe the research progress in this topic. There were 3,252 publications for three decades during 1988-2021. The number of studies was low during the first 14 years but has risen consistently in the following two decades. The average publications per year were only 4.8 during 1988-2002, which jumped to 113 per year during 2003-2012, and 227 per year during 2013-2021. These publications came from 83 countries/regions, with the United States, Germany, and Italy leading positions. Most studies were published in Investigative Ophthalmology Visual Science, and Ophthalmology was the most cited journal. We found 9,993 authors, with Bandello F having the most publications and Jonas JB being the most frequently co-cited. According to our research, the most popular keyword is triamcinolone acetonide (TA). Macular edema, diabetic macular edema (DME), retinal vein occlusion (RVO), dexamethasone (DEX), fluocinolone acetonide (FA), and some other keywords were commonly studied in this field. In conclusion, the bibliometric analysis provides a comprehensive overview of steroid hotspots and developmental tendencies in the macular edema study. While anti-VEGF therapy is the first-line treatment for DME and RVO-induced macular edema, steroids implant is a valid option for these DME patients not responding to anti-VEGF therapy and non-DME patients with macular edema. Combined therapy with anti-VEGF and steroid agents is vital for future research.

    The 100 Most Impactful Papers in Hand and Upper Extremity Surgery over the Last 25 Years: A Bibliometric Analysis of the Orthopaedic Literature.
    Neil V Shah, John J Kelly, Jared M Newman, Karan Dua, Alba Avoricani, Bassel G Diebo, Steven M Koehler.
      Introduction  Despite growth in hand/upper extremity investigation, impactful studies have not been thoroughly identified. Previous studies have been limited in scope. This study sought to identify and characterize the most impactful orthopaedic papers in hand/upper extremity over the past 25 years. Materials and Methods  The top 1,000 hand/upper extremity orthopaedic studies published from 1992 to 2017 were identified with Web of Science. After screening for relevance in order of decreasing citation number, the top 100 articles were identified for bibliometric analysis. Results  The mean number of authors and citations were 4.51 (range, 1-21) and 169.4 (range, 105-863). Common study types included, case series ( n = 52), randomized controlled trial ( n = 17), and prospective cohort ( n = 16), which predominantly covered topics related to shoulder ( n = 34), wrist/forearm ( n = 21), and hand ( n = 17). Among wrist/forearm and hand studies, distal radius fractures ( n = 12) and nerve-related topics ( n = 10) were most frequently analyzed. Most studies were of level IV ( n = 51) and level II ( n = 16) evidence. Recent studies had greater impact (mean citations/year: 2011, 82.7/year vs. 1992, 16.1/year). Conclusion  Most of the 100 top orthopaedic articles in hand/upper extremity were of level IV or II evidence, retrospective, and nonrandomized. Despite an observed recent increase in level I studies, a lack of prospective, randomized trials is apparent.

    Atrial Fibrillation and Depression: A Bibliometric Analysis From 2001 to 2021.
    Yuzhen Ai, Yaxuan Xing, Longmei Yan, Dan Ma, Anran Gao, Qiwu Xu, Shan Zhang, Ting Mao, Qiu Pan, Xiaojuan Ma, Jingchun Zhang.
       Background: The control of diseases related to atrial fibrillation (AF) may reduce the occurrence of AF, delay progression, and reduce complications, which is beneficial to the prevention and treatment of AF. An increasing number of studies have shown that AF is associated with depression. However, to date, there has not been a bibliometric analysis to examine this field systematically. Our study aimed to visualize the publications to determine the hotspots and frontiers in research on AF and depression and provide guidance and reference for further study.
    Methods: Publications about AF and depression between 2001 and 2021 were retrieved from the Web of Science Core Collection (WOSCC) database. CiteSpace 5.8. R1, VOSviewer 1.6.16, and Excel 2019 software tools were used to conduct this bibliometric study.
    Results: In total, 159 articles and reviews were analyzed. The number of publications has been increased sharply since 2018. David D. McManus had the largest number of publications. The most prolific country was the USA with 54 publications but the centrality was <0.1. The most prolific institution was Northeastern University. Three clusters were formed based on keywords: The first cluster was composed of atrial fibrillation, depression, anxiety, symptoms, ablation, and quality of life, et al. The second cluster were risk, prevalence, mortality, heart failure, association, et al. While the third cluster included anticoagulation, impact, stroke, management, warfarin, et al. After 2019, stroke and prediction are the keywords with strongest citation bursts.
    Conclusion: Research on AF and depression is in its infancy. Cooperation and exchanges between countries and institutions must be strengthened in the future. The effect of depression on prevalence and mortality in AF, depression on ablation in AF, and impact of depression on anticoagulation treatment in AF have been the focus of current research. Stroke prevention (including anticoagulant therapy) is the research frontier, which may still be the focus of research in the future.

    Bibliometric Analysis of Ferroptosis in Stroke From 2013 to 2021.
    Yuhua Chen, Tianlin Long, Quanhua Xu, Chi Zhang.
      Background: Stroke is a major cause of long-term disability and death, but the clinical therapeutic strategy for stroke is limited and more research must be conducted to explore the possible avenues for stroke treatment and recovery. Since ferroptosis is defined, its role in the body has become the focus of attention and discussion, including in stroke. Methods: In this work, we aim to systematically discuss the "ferroptosis in stroke" research by bibliometric analysis. Documents were retrieved from the Web of Science Core Collection database on October 30, 2021. Statistical analysis and visualization analysis were conducted by the VOSviewer 1.6.15. Results: Ninety-nine documents were identified for bibliometric analysis. Research on "ferroptosis in stroke" has been rapidly developing and has remained the focus of many scholars and organizations in the last few years, but the Chinese groups in this field still lacked collaboration with others. Documents and citation analysis suggested that Rajiv R. Ratan and Brent R. Stockwell are active researchers, and the research by Qingzhang Tuo, Ishraq Alim, and Qian Li are more important drivers in the development of the field. Keywords associated with lipid peroxidation, ferroptosis, iron, oxidative stress, and cell death had high frequency, but apoptosis, necroptosis, pyroptosis, and autophagy had scant research, and there may be more research ideas in the future by scholars. Conclusion: Further exploration of the mechanisms of crosstalk between ferroptosis and other programmed cell death may improve clinical applications and therapeutic effects against stroke. Scholars will also continue to pay attention to and be interested in the hot topic "ferroptosis in stroke", to produce more exciting results and provide new insights into the bottleneck of stroke treatment.

    Influential Studies in Orthopaedic Platelet-Rich Plasma Research Are Recent and Consist of High Levels of Evidence: A Review of the Top 50 Most Cited Publications.
    Jacob F Oeding, Drew A Lansdown, Philipp Leucht, Joseph A Bosco, Jaclyn Konopka, Claudette M Lajam.
      Platelet-rich plasma (PRP) has garnered widespread and increasing attention in recent years. We aimed to characterize the most influential articles in PRP research while clarifying controversies surrounding its use and clinical efficacy and identifying important areas on which to focus future research efforts. The Science Citation Index Expanded subsection of the Web of Science Core Collection was systematically searched to identify the top 50 cited publications on orthopedic PRP research. Publication and study characteristics were extracted, and Spearman's correlations were calculated to assess the relationship between citation data and level of evidence. The top 50 articles were published between the years 2005 and 2016, with 68% published in the year 2010 or later. Of the 33 studies for which level of evidence was assessed, the majority were of level I or II (18, 54.5%). Seventeen articles (34%) were classified as basic science. All clinical studies were prospective, and most (12 studies, 60%) included a high number of metrics related to the PRP preparation protocol and composition. Knee osteoarthritis was the most common topic among clinical studies in the top 50 cited articles (11 studies, 34%). More recent articles were associated with higher citation rates (ρ = 0.46, p < 0.001). The most influential articles on orthopaedic PRP research are recent and consist of high-level of evidence studies mostly. Randomized controlled trials were the most common study type, while basic science articles were relatively less common. The most influential clinical studies reported a high number of metrics related to their PRP preparation protocol and the final PRP composition. These results suggest a rapidly evolving field with the potential to better explain inconsistent clinical results with improved understanding and documentation of basic science concepts such as PRP composition, preparation, and combination techniques.

    Ahmed A Khalifa, Mohamed A Haridy, Mohamed Khashaim, Takla Adel Haroon, Amr A Fadle, Ahmed Khalil Attia.
       Background: This study aimed to evaluate the Middle East (ME) countries' contribution to the Journal of Arthroplasty (JOA)'s publications in the past 20 years.
    Methods: All articles published in JOA from 2000 to 2020 were evaluated for the contribution prevalence of ME countries' authors, which were divided into category I, if all the authors were affiliated to ME institutions, and category II, if at least one coauthor affiliated to ME institutions was listed in the articles with other international authors.
    Results: A total of 7837 original articles were evaluated. Authors affiliated with ME institutions contributed to 144 (1.8%) articles (148 individual country contributions) from ten (62.5%) out of a total of 16 ME countries. Sixty-eight articles (47.2%) were classified as category I; cooperation between different ME institutes (The authors were from two different ME countries.) was reported in two (1.4%) articles. The top five contributing countries were Egypt, Iran, Israel, Saudi Arabia, and Turkey, contributing 89.2% of the total articles published by ME institutions. Out of the 144 articles, 80 (55.6%) articles were published between 2016 and 2020, 37 (25.7%) articles between 2011 and 2015, and 29 (20.1%) articles between 2000 and 2010. There was a 15.7% mean annual growth in the percentage of ME articles.
    Conclusion: Although there was an increasing trend in the contributions of ME countries' authors to JOA publications over the past 20 years, the overall contribution is still low; moreover, the cooperation between ME institutions is minimal.

    Twitter Mentions Influence Academic Citation Count of Shoulder and Elbow Surgery Publications.
    Suleiman Sudah, Robert D Faccone, Matthew H Nasra, David Constantinescu, Mariano E Menendez, Allen Nicholson.
      Background Social media use among scholars and journals is growing and has augmented the academic impact of published articles in several areas of medicine. However, the influence of social media postings on academic citations of shoulder and elbow surgery publications is not known. In this study, we sought (1) to quantify the adoption of Twitter use for the dissemination of research publications by three prominent shoulder and elbow surgery journals and (2) to determine the correlation between Twitter mentions and academic citations in shoulder and elbow surgery publications. Methodology A total of 396 original research articles from three shoulder and elbow surgery journals (Journal of Shoulder and Elbow Surgery (JSES), Shoulder & Elbow, and JSES International) published in 2018 were assessed 34 to 45 months after print publication. For each article, the total number of Twitter mentions were obtained using Altmetric Bookmarklet and grouped into those tweeted by authors, an official outlet, or a third party. Article citation data was obtained using the Google Scholar search engine. Pearson correlation was used to determine the association between the number of Twitter mentions and citation count. Results Of all articles, 51% (202/396) had at least one Twitter mention. Of all Twitter mentions, 12.7% (367/2,879) occurred within the first week of online publication dates, while 51.5% (1,482/2,879) occurred between online and print publication dates. Articles mentioned on Twitter had 1.3-fold more Google Scholar citations (17.7 ± 15.2) than articles with no Twitter mentions (14.0 ± 15.7) (p = 0.017). The number of Twitter mentions had a weakly positive correlation with academic citation count (r = 0.25; p < 0.001). No significant difference in academic citation rates was found between articles tweeted by authors or official outlets when compared to articles tweeted by a third party only (p = 0.97 and p = 0.34, respectively). Conclusions Approximately half of shoulder and elbow surgery publications are shared on Twitter, with the majority of the activity occurring prior to their print publication date. The finding that tweeted articles have more academic citations within three years of release suggests that social media activity seems to amplify the academic impact of shoulder and elbow surgery publications.

    Results of 25 years of Maghrebian scientific medical research in the Grand Maghreb. Bibliometric analysis of the Scimago platform (1996-2020).
    Ahmed Ben Abdelaziz, Sara Melki, Dhekra Chebil, Mohamed Azzaza, Asmaa Quessar, Abdeljalil Bezzaoucha.
       OBJECTIVE: Describe the trend and the characteristics of the positioning of Maghreb medical production and its visibility, at the global, African and Arab level, following an in-depth reading of the Scimago platform, over a period of 25 years (1996-2020 ).
    METHODS: This is an in-depth reading, centered on the Maghreb, of the Maghreb medical production referenced on the Scimago platform, from 1996 to 2020. The bibliometric extracts were based on the number of published "documents" and the index H: number of articles (h) from a country having received at least h citations. The benchmarking of the productivity and medical visibility of the five Maghreb countries (Tunisia, Morocco, Algeria, Libya, Mauritania) was carried out at the global (237 countries), African (59 countries) and Arab (21 countries) level.
    RESULTS: Following the first African countries producing the most medical documents (South Africa, Egypt and Nigeria), the position of the Maghreb countries varied from 4 in Tunisia to 36 in Mauritania. In Arab countries, the position of medical production, dominated by Egypt and Saudi Arabia, was 12 and 18, successively in Algeria and Libya. The evolution of medical documents recorded a cross between Tunisia and Morocco in 2014, followed by a deceleration in Moroccan production. In the Maghreb, the h index varied from 154 in Tunisia to 29 in Mauritania.
    CONCLUSION: In addition to its weak position in the world, African and Arab rankings over the past 25 years, Maghreb medical research has been characterized by a major fluctuation. The "Alliance for Excellence" charter of the PRP2S Network, based on the promotion of university essays and electronic journals, constitutes an operational roadmap for the development of the production and visibility of research in the Maghreb.

    Evolution of intracranial-intracranial bypass surgery: a bibliometric analysis.
    Vamsi P Reddy, Andreas Seas, Nitish Sood, Visish M Srinivasan, Joshua S Catapano, Michael T Lawton.
       OBJECTIVE: Modern cerebrovascular bypass surgery uses either extracranial-intracranial (EC-IC) or intracranial-intracranial (IC-IC) approaches. Compared to EC-IC bypasses, IC-IC bypasses allow neurosurgeons to safely address tumors, aneurysms, and other lesions using shorter grafts that are well matched to the size of recipient vessels. Fewer than 100 articles have been published on IC-IC bypasses to date, compared to more than 1000 on EC-IC bypasses. This study examines the growth of interest and innovation in the field of IC-IC bypass.
    METHODS: PubMed and Web of Science were searched using keywords specific to IC-IC bypass, yielding 717 articles supplemented with 36 reports from other databases and gray literature. The articles were reviewed, and 98 articles were selected for further evaluation. Final articles were categorized as innovations or retrospective studies. Publication metrics were passed through an analytic program to assess statistical measures of growth.
    RESULTS: The number of publications describing innovations (n=52) and retrospective studies (n=46) in IC-IC surgical techniques grew exponentially (R2=0.983 and R2=0.993, respectively), with both interest and research in the field increasing. The rate of publications in each group also increased. In recent years, a growing number other institutions have researched and published on IC-IC bypasses.
    CONCLUSIONS: As more work is done on IC-IC bypasses, it is critical for knowledge to be shared through research, collaboration, publication, and early teaching within residency training programs. This field has grown exponentially in the past 2 decades and has yet to reach an inflection point, indicating possible additional interest and growth over time.

    Bibliometric dataset (1990-2019) concerning 35 city labels dealing with sustainable urbanism.
    Simon Joss, Daan Schraven, Martin de Jong.
      This data article presents a tripartite dataset that formed the empirical basis for a comprehensive bibliometric analysis of the use of city labels denoting sustainable urbanism in the scientific literature (Schraven, 2021). The tripartite dataset was generated using the abstract and citation database Scopus (Elsevier). Dataset A lists 148 city labels denoting different approaches to urban planning and development. It was used to select 35 city labels that specifically address sustainable urbanism ('sustainable city', 'smart city', 'compact city' etc.). Dataset B references 11,337 journal and review articles spanning the period 1990-2019. All retrieved articles contain at least one of the 35 city labels in the title, abstract, and author keywords. This database was used to calculate the frequency of the selected city labels across time, and to analyze the co-occurrences of city labels. It was further used to calculate the future trajectory of scientific outputs using the Logistic Growth Model (LGM). Dataset C entails 22,820 author keywords extracted from across the 11,337 articles. This was used to analyze the co-occurrences of keywords with city labels. The data article describes the methods of data collection and curation, the analysis performed, and the potential for reusing the data for further research. The comprehensiveness of the bibliometric corpus - spanning three decades and 35 city labels - lends itself to further investigation of how sustainable urban development has evolved as a topic in the scientific literature since the 1990s. Furthermore, the robust methodology developed could be adapted to other scientific repositories and, indeed, other research problems and questions.

    Khalid Mehmood, Sana Mushtaq, Yansong Bao, Saifullah, Sadia Bibi, Muhammad Yaseen, Muhammad Ajmal Khan, Muhammad Mohsin Abrar, Zaid Ulhassan, Shah Fahad, George P Petropoulos.
      As a result of extreme modifications in human activity during the COVID-19 pandemic, the status of air quality has recently been improved. This bibliometric study was conducted on a global scale to quantify the impact of the COVID-19 pandemic on air pollution, identify the emerging challenges, and discuss the future perspectives during the course of the ongoing COVID-19 pandemic. For this, we have estimated the scientific production trends between 2020 and 2021 and investigated the contributions of countries, institutions, authors, and most prominent journals metrics network analysis on the topic of COVID-19 combined with air pollution research spanning the period between January 01, 2020, and June 21, 2021. The search strategy retrieved a wide range of 2003 studies published in scientific journals from the Web of Sciences Core Collection (WoSCC). The findings indicated that (1) publications on COVID-19 pandemic and air pollution were 990 (research articles) in 2021 with 1870 citations; however, the year 2020 witnessed only 830 research articles with a large number 16,600 of citations. (2) China ranked first in the number of publications (n = 365; 18.22% of the global output) and was the main country in international cooperation network, followed by the USA (n = 278; 13.87% of the global output) and India (n = 216; 10.78 of the total articles). (3) By exploring the co-occurrence and links strengths of keywords "COVID-19" (1075; 1092), "air pollution" (286; 771), "SARS-COV-2" (252; 1986). (4) The lessons deduced from the COVID-19 pandemic provide defined measures to reduce air pollution globally. The outcomes of the present study also provide useful guidelines for future research programs and constitute a baseline for researchers in the domain of environmental and health sciences to estimate the potential impact of the COVID-19 pandemic on air pollution.

    Bibliometric Analysis of Research Areas, Publication Hierarchy and Gender Authorship in German University Orthopaedic Surgery.
    Jennifer Preut, Karl-Heinz Frosch, Eike Sebastian Debus, Reinhart T Grundmann.
       BACKGROUND: The aim of the present bibliometric study was to record the focus of publications, type of study and publication activities depending on the hierarchy level and gender of the authors of German university departments for orthopaedic surgery.
    MATERIAL AND METHODS: The publication performance of the staff surgeons, consisting of chief and senior physicians, section and division heads of 39 German university departments of orthopaedic surgery university hospitals, was recorded over a period of 10 years (January 1, 2010 to December 31, 2019). All publications were considered that were listed in PubMed and for which the staff surgeons were first or last authors. In addition, the impact factor (IF) and the h-index were determined.
    RESULTS: 1739 (39.2%) publications were compiled by 180 staff surgeons of university departments for trauma surgery and 2699 (60.8%) publications by 343 surgeons in departments of orthopaedics and trauma surgery. Most publications were related to injuries or impairments of the lower extremity including the hip (n = 1626; 38.1%), followed by the upper extremity (n = 737; 17.3%). These publications focussed on diagnostic testing (25.5%), surgical techniques (19.1%) or special osteosyntheses (16.9%). The highest average IF per publication was achieved by publications on plastics (IF 2.02), on outcome (IF 1.96) and on diagnostic testing (IF 1.93). Heads of departments were first authors in 18.8%, senior physicians with management functions in 40.7% and senior physicians without management functions in 69% of papers and last authors in 81.2%, 49.3% and 31.0% of articles, respectively. 64 of 523 staff surgeons (12.2%) were women. 306 authors (6.1%) were women, corresponding to 4.8 authorships per female surgeon - significantly for male surgeons (10.3 authorships per male surgeon).
    CONCLUSION: In the present study, among senior physicians with a management function, the share of publishing surgeons was 59.1% for women, but 85.5% for men. In contrast, in the group of senior physicians without management function female and male surgeons were almost equally represented (57.5% vs. 60.5%). It must therefore be asked whether the work life balance is more difficult to meet for women than for men with longer careers. Mentoring programs are required to support the publication activities of the increasing number of female applicants in the future.

    A Co-word Analysis of Selected Science Education Literature: Identifying Research Trends of Scaffolding in Two Decades (2000-2019).
    Tzu-Chiang Lin, Kai-Yu Tang, Shu-Sheng Lin, Miao-Li Changlai, Ying-Shao Hsu.
      This study aims to identify research trends of scaffolding in the field of science education. To this end, both descriptive analysis and co-word analysis were conducted to examine the selected articles published in the Social Science Citation Index journals from 2000 to 2019. A total of 637 papers were retrieved as research samples through rounds of searching in Web of Science database. Overall, this study reveals a growing trend of science educators' academic publications about scaffolding in the recent two decades. In these sample papers, from 1,487 non-repeated keywords, we extracted 286 author-defined keywords shared by at least two studies as a benchmark dictionary. A series of co-word analyses were then conducted based on the dictionary to reveal the underlying co-occurring relationships of the words in title and abstract of the sample papers. Results showed that "scaffolding," "support," and "design" were the top three most frequently used keywords during 2000 and 2019. Visualization of co-word networks in each 5-year period further helps clarify both educators' common research foci and relevant research trends. Derived discussion and potential research directions are also provided.

    Evolution and Trends in Male Versus Female Authorship of Articles in Flagship Orthopaedic Journals From 1995 to 2020.
    Sarah N Powell, John C Hunting, Landon P Frazier, Laura E Keeling, Jessie Janowski.
       INTRODUCTION: The gender disparity in orthopaedic surgery has been recognized for many years. Because research affects promotions, this study investigates trends in female authorship in three journals over the past 25 years for both first and senior authors.
    METHODS: All articles from Journal of Bone and Joint Surgery, Journal of the American Academy of Orthopaedic Surgeons, and Clinical Orthopaedics and Related Research from 1995 to 2020 in 5-year intervals were downloaded, and the data for first and senior authors were extracted. The sex of the first and senior authors was determined using the validated Genderize algorithm. The demographics of the first and senior author cohorts were analyzed using chi square tests. The trends in female authorship controlling for year and journal were assessed with logistic regression models.
    RESULTS: Within the studied journals, 5,636 individuals were identified as first authors and 4,572 as senior authors. Sex was determined for 82.59% of the authors. Female first authorship increased significantly from 1995 to 2020 (6.70% to 15.37%, P < 0.001). Similarly, female senior authorship increased significantly from 1995 to 2020 (8.22% to 13.65%, P < 0.001). Overall, there was no significant difference in gender composition of authors between journals (P = 0.700 first author and P = 0.098 senior author). Women were much more likely to publish as first or senior author in later years, regardless of the journal (P < 0.001 first author and P < 0.001 senior author).
    DISCUSSION: Female authorship in prominent orthopaedic journals has increased markedly from 1995 to 2020 with interjournal differences in senior author gender disparity. Although female orthopaedic surgeons publish at rates equal to or greater than their representation in the specialty, additional research is needed into the persistence of gender disparities in orthopaedics.

    [Research status and trends of acupuncture and moxibustion for cancer：a bibliometric analysis based on CiteSpace and VOSviewer].
    Li-Ling Li, Yu-Xiang Wan, Qiao-Li Zhang, Yan-Yan Lian, Chun-Guang Zhang, Jin-Chang Huang.
      To analyze the research status of acupuncture and moxibustion for cancer at home and abroad in the past 45 years by using bibliometric and scientific knowledge map methods，and explore the development trends in future. The literature of acupuncture and moxibustion for cancer was retrieved from CNKI and Web of Science (WOS) till December 31, 2020 since the database establishment, and CiteSpace and VOSviewer software were used to perform visual map analysis through cooperation network, keyword co-occurrence, keyword timeline, keyword emergence and other methods. Totally, 1 585 literature in CNKI and 1 564 literature in WOS were included, and the annual publication amount showed a fluctuating upward trend. Cooperation between countries was centered on China and the United States, and there was relatively little cooperation among different institutions. The analysis of keyword and cited literature showed that researches focused on the control of acupuncture and moxibustion therapy on cancer complications and adverse reactions of western medicine. The main research types in WOS were systematic review and randomized controlled trial (RCT), while in CNKI was review, depth studies on mechanism of acupuncture and moxibustion for cancer were rare. The concern about the quality of life of cancer patients may become research emphasis in the field of acupuncture and moxibustion for cancer in future, and the research scope tends to integrative and holistic oncology.

    Geographic Distribution, Number, and Types of Papers Published in International Cytopathology Journals in the Last 5.5 Years: A Preliminary Study.
    Büşra Yaprak Bayrak, Nadir Paksoy.
       OBJECTIVE: The aim of this study was to explore the geographic distribution and number of papers published in international and Science Citation Index (SCI)-indexed cytology journals based on their country of origin.
    MATERIALS AND METHODS: A country-based geographic analysis of studies published over a 5.5-year period from January 2016 to June 2021 in 5 cytopathology journals indexed as SCI and SCI-E with an impact factor higher than 1 (Cancer Cytopathology, Cytopathology, Diagnostic Cytopathology, Acta Cytologica, and CytoJournal) and papers categorized as "original" and "other" was performed.
    RESULTS: A total of 3,063 papers were found, with 1,466 (47.8%) categorized as "original" papers and 1,597 (52.1%) designated as "other" papers. These papers were submitted from 62 different countries. The five countries with the greatest number of papers were the USA (38.4%), India (16.8%), Japan (7.4%), Italy (5.5%), and Brazil (3.1%). A general subgroup analysis was also performed on the original studies without a country breakdown. Cytomorphological, cytomorphological-immunohistochemical, and molecular assessments compose 38.5%, 45.7%, and 15% of the subgroups, respectively.
    CONCLUSION: The number of academic papers originating from developing countries in the field of cytopathology has increased in recent years. Although most scientific papers are produced in developed countries, the rate in these countries is much lower than that in some developing countries as the rate of academic growth in developed countries has stabilized. Despite the widespread and sophisticated implementation of cytology in daily practice in Western European countries outside the UK, such as Germany and the Netherlands, and in Scandinavian countries and other developed countries, such as Australia and Canada, these countries rank in the middle to lower end of countries producing cytology papers. Meanwhile, there has been an increase in the number of cytology papers published by authors from Southern European countries, such as Italy (ranked 4th) and Spain (ranked 6th), and Turkey (ranked 8th). There is a remarkable increase in cytology papers originating from Asia, particularly India, Japan, and China.
    SUMMARY: We aimed to present a basic survey of the geographic distribution of manuscript submissions to high-impact cytopathology journals and to point out emerging trends in cytology utilization and basic research. However, our results show that the landscape of cytology is changing and suggest geographic regions that are ripe for the production of novel "points of view" and new research findings.

    Factors affecting time to publication in information science.
    Zehra Taşkın, Abdülkadir Taşkın, Güleda Doğan, Emanuel Kulczycki.
      Publication speed is one of the important aspects of scholarly communication since various research performance evaluation systems are based mostly on published papers. This study aims to reveal the factors affecting the publication speed of journals. In this context, six information science journals: ASLIB Journal of Information Management, Journal of Documentation, Journal of Informetrics, Journal of the Association for Information Science and Technology, Online Information Review, and Scientometrics are analysed in terms of time to publication (from submission to decision). Our results show that publication time is significantly shorter when an editorial board member or a productive author of a given journal is one of the authors, in compare with the articles. submitted by other authors. The number of authors has a time-prolonging effect on publication time, as expected. On the other hand, publications with more citations were accepted in a shorter time. The papers with authors from central countries and high-income countries have an advantage of shorter publication time. Thus, this study shows that researchers who publish papers with popular and successful researchers from central countries have the advantage of the speed of publication which may have substantial effects on the future academic work, especially of early career researchers.

    A bibliometric evaluation of the impact of theories of consciousness in academia and on social media.
    Andy Wai Kan Yeung, Cody A Cushing, Alan L F Lee.
      Consciousness science has faced both opportunities and challenges in recent years. Some popular theories of consciousness have been described as unfalsifiable and some as "overpromoted". To objectively evaluate the state of consciousness science as a field, we analyzed bibliometric data for five major theories of consciousness: Global workspace (GWT), Higher-order (HOT), Integrated information (IIT), Local recurrent (LRT), and Quantum theories (QT). We analyzed academic publications, citations, and Twitter activity for each theory. We found that IIT had the highest growth rates in quantity metrics (e.g. publication and citation counts) but was worse in quality metrics (e.g., per-publication citations, proportion of citations with empirical support/contradiction). On social media, IIT and QT were the most-tweeted theories, but their tweets mostly came from the general public. Our findings suggest that a theory's fast growth in quantity and lack of quality could be explained by its overpromotion on social media.

    Xinxin Wang, Yong Qin, Zeshui Xu, Marinko Škare.
      This study explores the problems related to the development of innovation research in the field of business and economics and the change in their characteristics following the coronavirus disease 2019 (COVID-19) pandemic. We compile a comprehensive bibliometric analysis of 17,277 pre-epidemic publications and 4,240 post-epidemic publications from the Web of Science. Using bibliometric methods and visualization tools, we present the changes in these publications following the COVID-19 pandemic, and identify the influential countries and regions, sources, and references, and obtain features of keywords over time. The results show that innovation research is rich in content, and involves a wide range; it has been focusing on emerging topics, such as those concerning low-carbon, innovation forms, and epidemic environments, following the COVID-19 pandemic. This study contributes to the body of knowledge on innovation, and helps to understand the features and structures of innovation research in business and economics.

    Growth and globalization of point-of-care ultrasound publications in emergency medicine.
    Campbell Belisle Haley, Dina McKelvy, David C Mackenzie.
       OBJECTIVES: Since the introduction of point-of-care ultrasound (POCUS) in emergency medicine (EM), the applications, indications, and training for POCUS have grown. POCUS training in EM residency is standard and POCUS fellowships are common. We sought to quantify and characterize changes in POCUS publications over time with a scoping review of the literature METHODS: We conducted a structured keyword search of high impact EM journals according to 2019 journal citation reports and other journals publishing POCUS studies between 2000-2019. Two abstractors recorded whether the publication was POCUS related, the type of publication, and author affiliation by department and country. We included studies with at least one author affiliated with a department of EM. Agreement between abstractors was tested.
    RESULTS: The number of POCUS-related publications grew from a mean of 8.8 publications/year 2000-2004 to 134.8 publications/year from 2015-2019. The most common publication type was case reports or series (44%). The proportion of publications from outside the United States (US) decreased over time. Between 2000 and 2004 89% of publications came from authors affiliated with US institutions; from 2015-2019 this had decreased to 64%. Agreement between abstractors was excellent (Cohen's k = 0.89) CONCLUSIONS: POCUS publications increased substantially between 2000-2019. The most common type of publication was a case report, which was consistent throughout the study period. Authorship from outside the US increased. Publications yielding high-quality evidence from observational or controlled studies represented a low proportion of the total number of studies.

    Gender Diversity in Hand Surgery Leadership.
    Alyssa K Brisbin, Wendy Chen, Ezequiel Goldschmidt, Brandon T Smith, Debra A Bourne.
       BACKGROUND: Diversity in leadership drives innovation; however, women are underrepresented in leadership positions across academic medicine. The aim of this study was to assess the current gender representation in hand surgery leadership positions.
    METHODS: This was a cross-sectional analysis of leaders in hand surgery. Leaders were defined as President, Board and Committee members of the American Society for Surgery of the Hand and the American Association for Hand Surgery, as well as hand surgery fellowship program directors and physician lead editors of peer-reviewed hand journals. The representation of women in leadership was compared to the percentage of female hand fellows over the same period. Years in practice, academic rank, additional degrees, h-index, m-index, National Institutes of Health (NIH) funding, publications, and citations were compared between male and female leaders.
    RESULTS: Twenty-nine of 213 leadership positions (13.6%) are held by women which is fewer than would be expected based on hand surgery fellowship composition. Female leaders were earlier in practice than their male counterparts (13.5 ± 5.7 versus 20.8 ± 11.1 years, P < .01). Women were more likely to hold position of assistant professor and less likely to be full professors (P < .05). There was no gender difference in NIH funding, h-index, m-index, publications, or citations. The greatest gender disparity was at the level of National Society President, which is a title held by only 2 women and 119 men.
    CONCLUSIONS: Gender disparities in hand surgery exist and are accentuated at the leadership level. Further work is needed to decrease leadership promotion disparities between men and women.

    The Fertility of a Concept: A Bibliometric Review of Human Flourishing.
    Manuel Cebral-Loureda, Enrique Tamés-Muñoz, Alberto Hernández-Baqueiro.
      Human flourishing is a thriving concept, whose use has greatly increased among academic researchers from a variety of fields, from the arts and humanities and psychology to the social and environmental sciences and economics. To better understand the concept's success, this work proposes a bibliometric review, in which statistical methods and data mining were used to analyze 1829 documents, chosen from the Scopus database by searching the term "human flourishing". Through cluster and network analyses, the study shows the concept's evolution and composition, as well as its current tensions and trends, in which the predominantly psychological approach is being compensated with social concerns and the search for justice. Furthermore, the concept's strong philosophical roots provide it with abstract richness and great fertility, which can be seen in keywords, such as virtue or eudaimonia. This bibliometric review proved to be useful for this type of study, despite the limitations imposed by the characteristics of the Scopus database itself.

    Gamification as a Promoting Tool of Motivation for Creating Sustainable Higher Education Institutions.
    Johanna Andrea Navarro-Espinosa, Manuel Vaquero-Abellán, Alberto-Jesús Perea-Moreno, Gerardo Pedrós-Pérez, Maria Del Pilar Martínez-Jiménez, Pilar Aparicio-Martínez.
      Higher Educational Institutions (HEIs) are responsible for creating healthy and sustainable environments for students and teachers through diverse educational paradigms such as gamification. In this sense, the Healthy People 2030 and the Sustainable Development Goals indicated the imperative to provide inclusive and equitable quality education to promote a healthy environment and life. The principal objective was to analyse the impact of gamification on health development in HEIs, highlighting their positive and negative effects. To achieve such an objective, a bibliometric analysis was carried out. The 257 documents showed no significant increasing trend in the last decade (p &gt; 0.05) related to the pandemic. Most of the publications were conferences (45%), and the few published articles were the documents with more citations (p &lt; 0.001). According to their index in Journal Citation Reports, there were significant differences between the citations of articles published in journals (p &lt; 0.001). The analysis of journal co-citations showed that the leading journals (such as Computers in Human Behavior) had a significant part in the clusters formed (p &lt; 0.001), conditioning also the keywords, especially the term "motivation". These findings were discussed, concluding that the experimental studies focused on the teachers' adverse effects are yet to come.

    Global Research Trends in Gestational Diabetes Mellitus from 2000 to 2020: A Bibliometric Study.
    Hongyan Chen, Fengxiang Wei, Xiaohang Chen, Ken Chen.
       AIMS: This study analyzed major trends and topics in the field of gestational diabetes mellitus research between 2000 and 2020.
    METHODS: Studies that investigated gestational diabetes mellitus published between 2000 and 2020 were retrieved from the Web of Science Core Collection database. Data from the identified studies were analyzed using CiteSpace software.
    RESULTS: A total of 22,713 publications were retrieved, among which 21,722 publications were included in this scientometric analysis. Clustering analysis revealed 13 themes across all fields. Physical activity is an emerging trend. Co-word analysis showed that subject high-frequency keywords were: risk factor, obesity, insulin resistance, prevalence, and association. Centrality indices identified the most influential keywords to be: body mass index, risk factors, gestational weight gain, and obesity. Burst keywords revealed that there were six research frontier subtopics: i) prediction of adverse neonatal outcomes in gestational diabetes mellitus; ii) postpartum period research - blood glucose levels and insulin resistance; iii) meta-analysis - understanding the best evidence in pregnancy gestational diabetes mellitus; iv) gene expression profiles and DNA methylation in gestational diabetes mellitus; v) biomarkers for predicting higher birth and children weights; and vi) discussion on diagnostic criteria for gestational diabetes mellitus classification.
    CONCLUSION: The number of studies on gestational diabetes mellitus is increasing. For two decades, the United States has been the global leader in the number of published studies. Studies on gestational diabetes mellitus are mainly from developed countries, with a few of them being from developing countries. An emerging field of research aims at elucidating the association between physical activity and gestational diabetes mellitus.

    On Health Effects of Resveratrol in Wine.
    Robin Haunschild, Werner Marx.
      We analyzed 3344 publications concerned with the health-related effects of resveratrol that occurs in wine and grapes. We discovered that publication activity increased until 2010 and decreased slightly afterwards. The most frequent author keywords were classified into six groups: (1) beverage-related keywords, (2) compound-related keywords, (3) disease-related keywords, (4) effect-related keywords, (5) mechanism-related keywords, and (6) broader keywords. By means of reference publication year spectroscopy, we analyzed and discussed the most frequently cited references (i.e., key papers) within the publication set. A rather large portion of the key papers exhibit a deliberative or positive attitude and report on the health effects of resveratrol, although limited data in humans preclude drawing unambiguous conclusions on its health-related benefits. From our analysis, we could not identify specific publications that provide a distinct change of direction of the ongoing scientific discourse. Moderate red wine consumption seems to bear the potential of being health promoting, whereas excessive alcohol consumption can induce liver cirrhosis and cancer.

    Perspective of Using Magnesium Oxychloride Cement (MOC) and Wood as a Composite Building Material: A Bibliometric Literature Review.
    Andreea Maier, Daniela Lucia Manea.
      The building industry is known as one of the biggest consumers of natural resources and an important producer of CO2 emissions. The biggest greenhouse gas emissions are recorded in the production of cement and metallic building materials. The purpose of this paper is to investigate if magnesium oxychloride cement (MOC) can be used as an alternative to the ordinary Portland cement in the mixture of wood-cement composite building materials in order to decrease the negative impact of the construction industry on the environment. The research methodology includes bibliometric literature research, a scientometric analysis and an in-depth discussion. The data used for the research were obtained by interrogating the ISI Web of Science database, selected using the guidelines of the PRISMA method and processed with the help of VOSviewer and Bibliometrix software. The research results indicate an increasing interest in this topic; for example, in the last five years, three times more articles were published on the subject of MOC cement than the number of all articles collected in previous years. Compared to ordinary Portland cement, MOC cement presents a good match with wood, so MOC can be a substitute for ordinary cement to manufacture wood-cement particleboard, especially for the wood species that have high incompatibility with ordinary cement.

    Intramural Grant Program to Promote Research Activity Among Early Career Faculty Members.
    Amarjit S Virdi, Giselle Sandi, Susan Chubinskaya.
       PROBLEM: Early grant support for junior faculty members appears to positively influence their career trajectory. The authors sought to determine whether provision of grant support that enables early-career faculty members to conduct clinical, basic science, or educational research improves their academic success and enhances retention.
    APPROACH: The authors compared career development and retention among 30 Cohn Fellowship recipients and 31 nonrecipients who participated in the same mentoring program. An award of $20,000 to the fellowship recipients ensured protected time for research for 1 year. Academic productivity of both groups was monitored for 6 years.
    OUTCOMES: The authors found statistically significant differences between the 2 groups regarding research funding and scholarly productivity. The Cohn Fellowship recipients received a total of $14.7 million in external funding versus $3.7 million for nonrecipients, reflecting mean funding of $588,116 and $196,658 per person, respectively (P < .01). Recipients published a total of 174 peer-reviewed articles versus 26 for nonrecipients, reflecting a mean of 7 and 1 per person, respectively (P < .001). Recipients gave a total of 268 presentations versus 25 for nonrecipients, with a mean of 11 and 1 per person, respectively (P < .001). Furthermore, 8 of the 25 recipients who stayed at Rush University (32%) were promoted to associate professor compared to 2 of the 19 (10.5%) nonrecipients (P = .15). A majority of the Cohn Fellows (25; 83.3%) stayed at Rush University during the study compared to 61% of nonrecipients (P = .06). These findings suggest that even small amounts of research support received early in a career can benefit the faculty and the university as a whole.
    NEXT STEPS: We plan to continue gathering data to increase sample size and analyze outcomes for specific variables (e.g., time, rank, gender, promotion, retention).

    COVID-19 and decent work: A bibliometric analysis.
    Rosley Anholon, Izabela Simon Rampasso, Thais Dibbern, Milena Pavan Serafim, Walter Leal Filho, Osvaldo L G Quelhas.
       BACKGROUND: The COVID-19 pandemic impacted the Sustainable Development Goals (SDGs). Among these impacts, those related to the SDG 8 can be highlighted. Consequently, the literature has addressed aspects related to economic growth and decent work.
    OBJECTIVE: This article aimed to evaluate the impact of the COVID-19 pandemic on decent work according to the literature.
    METHODS: For this, a bibliometric analysis was conducted. Data from Web of Science were collected, and VOSviewer software was used to perform the analysis.
    RESULTS: Regarding the results, four main clusters that govern the subject were identified. A first cluster (identified in red) evidenced the consequences of the pandemic to the generation of informal work, increasing poverty and the impacts on gender issues. A second cluster (identified in blue) addresses mental health and stress issues, especially for nurses professionals who experience a situation in the COVID-19 pandemic. The green cluster focused on unemployment, precarious employment, and work conditions, which were highly related to coronavirus contagion. Finally, the yellow cluster evidenced the final consequences when there is a substantial public health problem.
    CONCLUSIONS: The results presented here can be helpful to researchers interested in the, as it allows a broad and condensed view of important information about a relevant topic for sustainable economic development.

    Knowledge domain and research progress in green consumption: a phase upgrade study.
    Han Huang, Ruyin Long, Hong Chen, Qianwen Li, Meifen Wu, Xin Gan.
      Green consumption (GC), as one of the important initiatives to achieve the goal of carbon peaking and carbon neutrality, has attracted widespread attention from scholars in environmental and economic fields. This article reviews the literature on GC, asking two main questions: how can GC research be analyzed from macro, meso, and micro perspectives? How have the research topics in the field of GC evolved in international and Chinese academia? This study makes a visual analysis of knowledge domain based on the literature of Web of Science Core Collection and China National Knowledge Infrastructure, so as to reveal hot topics, stage division, and research trend of GC research. The results revealed the following: GC research is in a period of rapid growth, and it is mainly distributed in developed countries dominated by the USA and in developing countries dominated by China. There is a trend of interdisciplinary research on GC, such as ecology, psychology, health, systematics, politics, and economics, which indicates that GC research has become increasingly inseparable from human survival and health, psychological acceptance, and social development. For the international academia, GC research pays more attention to the transformation of consumer psychology, while the Chinese academia is more concerned with the regulation of consumer behavior and the activation of green emotions. Considering the focus and characteristics of GC supervision, this study proposes GC 3.0 with a consumer-oriented and emphasizing green emotions and proposes future application scenarios from four aspects: government supervision, social self-regulation, enterprise demonstration, and personal self-monitoring.

    Race and Ethnicity in Otolaryngology Academic Publications.
    Michael Lindeborg, Taseer Din, Cristóbal Araya-Quezada, Sabreena Lawal, Baveena Heer, Praveen Rajaguru, Myriam Joseph, Blake Alkire, Johannes Fagan.
       OBJECTIVE: Within otolaryngology, race is commonly included as a study covariate; however, its value in clinical practice is unclear. This study sought to explore how race and ethnicity have been used and applied over time in otolaryngology publications.
    DATA SOURCES: PubMed database.
    REVIEW METHODS: A systematic review was done to identify original otolaryngology studies between January 1, 1946, and June 25, 2020, with the following search terms: "otolaryngology" AND "race" OR "ethnicity."
    RESULTS: Of the 1984 yielded studies, 932 were included in the final analysis. Only 2 studies (0.2%) defined race, and 172 (18.5%) gave participants the opportunity to self-identify race. Less than half (n = 322, 43.8%) of studies controlled for confounders. One hundred studies (10.7%) linked race to genetic factors. An overall 564 (60.5%) made conclusions about race, and 232 (24.9%) mentioned that race is relevant for clinical decision making. The majority of studies had first and senior authors from high-income countries (93.9% and 93.8%, respectively). Over time, there was a significant increase in publications that controlled for confounders, the number of race categories used, and studies that highlighted disparities.
    CONCLUSION: Race and ethnicity are often poorly defined in otolaryngology publications. Furthermore, publications do not always control for confounding variables or allow participants to self-identify race. On the basis of our findings, we suggest 7 foundational principles that can be used to promote equitable research in otolaryngology publications. Future efforts should focus on incorporating research guidelines for race and ethnicity into journal publication standards.

    Gender disparity in academic orthopedic programs in Canada: a cross-sectional study.
    Jennifer Hunter, Ruby Grewal, Diane Nam, Kelly A Lefaivre.
       BACKGROUND: The majority of the literature on gender disparity in orthopedic surgery is from the United States; the Canadian perspective is lacking. The objective of this study was to determine the representation of women faculty members and the proportion of women faculty in published leadership positions in academic orthopedic divisions and departments across Canada.
    METHODS: In this cross-sectional study, we used a Web-based search strategy to identify faculty listings for all 17 academic orthopedic programs affiliated with the Association of Faculties of Medicine of Canada for the 2018/19 academic year. For each faculty member identified, we determined gender (man or woman), professorial rank and leadership positions. We compared regional gender differences among 3 groups: schools in eastern Canada and Quebec (6), Ontario (6) and western Canada (5). Gender comparisons were made for all variables of interest.
    RESULTS: We identified 809 orthopedic surgeons at the 17 Canadian academic institutions, of whom 96 (11.9%) were women. In eastern Canada and Quebec, 16.2% of the faculty were women, significantly above the national average (p = 0.03). The corresponding values for Ontario and western Canada were 8.9% (p = 0.1) and 11.4% (p = 0.7). There were no significant differences in the proportions of women and men at lower levels of promotion, but significantly more men than women had attained full professorship (65 [9%] v. 1 [1%], p = 0.002). Women surgeons were not represented in leadership roles or within faculty roles of distinction.
    CONCLUSION: In 2018/19, women orthopedic surgeons were underrepresented in faculty positions across academic orthopedic training programs in Canada, and were disproportionately underrepresented in promoted academic faculty roles and leadership positions. These data can be used to review and educate on equity in hiring and promotion, as well as to foster mentorship and transition planning.

    How research data deliver non-academic impacts: A secondary analysis of UK Research Excellence Framework impact case studies.
    Eric A Jensen, Paul Wong, Mark S Reed.
      This study investigates how research data contributes to non-academic impacts using a secondary analysis of high-scoring impact case studies from the UK's Research Excellence Framework (REF). A content analysis was conducted to identify patterns, linking research data and impact. The most prevalent type of research data-driven impact related to "practice" (45%), which included changing how professionals operate, changing organizational culture and improving workplace productivity or outcomes. The second most common category was "government impacts", including reducing government service costs and enhancing government effectiveness or efficiency. Impacts from research data were developed most frequently through "improved institutional processes or methods" (40%) and developing impact via pre-analyzed or curated information in reports (32%), followed by "analytic software or methods" (26%). The analysis found that research data on their own rarely generate impacts. Instead they require analysis, curation, product development or other forms of significant intervention to leverage broader non-academic impacts.

    A probabilistic model for co-occurrence analysis in bibliometrics.
    Xiaobei Zhou, Miao Zhou, Desheng Huang, Lei Cui.
      The co-occurrence analysis of Medical Subject Heading (MeSH) terms extracted from the PubMed database is popularly used in bibliometrics. Practically for making the result interpretable, it is necessary to apply a certain filter procedure of co-occurrence matrix for removing the low-frequency items due to their low representativeness. Unfortunately, there is rare research referring to determine a critical threshold to remove the noise of co-occurrence matrix. Here, we proposed a probabilistic model for co-occurrence analysis that can provide statistical inferences about whether the paired items co-occur randomly. With help of this model, the dimensionality of co-occurrence matrix could be reduced according to the selected threshold. The conceptual model framework, simulation and practical applications are illustrated in the manuscript. Further details (including all reproducible codes) can be downloaded from the project website: https://github.com/xizhou/co-occurrence-analysis.git.

    Publication rate and research topics of studies in pediatric kidney transplantation.
    Christian Patry, Stefanie Cordts, Lukas Baumann, Britta Höcker, Alexander Fichtner, Markus Ries, Burkhard Tönshoff.
       BACKGROUND: The quality of medical care for pediatric kidney transplant recipients depends on sound evidence from published clinical trials.
    METHODS: We examined the publication rate, time to publication, and factors associated with publication of studies in pediatric kidney transplantation registered on ClinicalTrials.gov from 1999 to 2020.
    RESULTS: We identified 136 studies with an overall enrollment of 36255 study participants, of which only 58.8% have been published yet. Unpublished studies included data from 14 350 participants. The median time to publication was 25 months (range, 0-117) with a significantly shorter time to publication in more recent years. The most frequently investigated research topic was immunosuppressants (49.3%), followed by perioperative management (11.0%) and infectiology (10.3%). The percentage of published studies was highest for the topic steroid withdrawal (87.5%), followed by infectiology (78.6%), and nutrition, sports and quality of life (71.4%). Studies, which were co-funded by industry, showed a significantly higher 5-year publication rate (p = 0.019).
    CONCLUSIONS: In conclusion, nearly half of all studies in pediatric kidney transplantation remain unpublished. Non-publication of studies might lead to a publication bias with a negative impact on clinical decision-making.
