    Knowledge Mapping of Multicriteria Decision Analysis in Healthcare: A Bibliometric Analysis.
    Zeqi Dai, Simin Xu, Xue Wu, Ruixue Hu, Huimin Li, Haoqiang He, Jing Hu, Xing Liao.
      Objective: Multicriteria decision analysis (MCDA) is a useful tool in complex decision-making situations, and has been used in medical fields to evaluate treatment options and drug selection. This study aims to provide valuable insights into MCDA in healthcare through examining the research focus of existing studies, major fields, major applications, most productive authors and countries, and most common journals in the domain.Methods: A bibliometric analysis was conducted on the publication related to MCDA in healthcare from the Web of Science Core Collection (WoSCC) database on 14 July 2021. Three bibliometric software (VOSviewer, R-bibliometrix, and CiteSpace) were used to conduct the analysis including years, countries, institutes, authors, journals, co-citation references, and keywords.
    Results: A total of 410 publications were identified with an average yearly growth rate of 32% (1999-2021), from 196 academic journals with 23,637 co-citation references by 871 institutions from 70 countries/regions. The United States was the most productive country (n = 80). Universiti Pendidikan Sultan Idris (n = 16), Université de Montréal (n = 13), and Syreon Research Institute (n = 12) were the top productive institutions. A A Zaidan, Mireille Goetghebeur and Zoltan Kalo were the biggest nodes in every cluster of authors' networks. The top journals in terms of the number of articles (n = 17) and citations (n = 1,673) were Value in Health and Journal of Medical Systems, respectively. The extant literature has focused on four aspects, including the analytic hierarchy process (AHP), decision-making, health technology assessment, and healthcare waste management. COVID-19 and fuzzy TOPSIS received careful attention from MCDA applications recently. MCDA in big data, telemedicine, TOPSIS, and fuzzy AHP is well-developed and an important theme, which may be the trend in future research.
    Conclusion: This study uncovers a holistic picture of the performance of MCDA-related literature published in healthcare. MCDA has a broad application on different topics and would be helpful for practitioners, researchers, and decision-makers working in healthcare to advance the wheel of medical complex decision-making. It can be argued that the door is still open for improving the role of MCDA in healthcare, whether in its methodology (e.g., fuzzy TOPSIS) or application (e.g., telemedicine).

    Pin Deng, Shulong Wang, Xiaojie Sun, Yinze Qi, Zhanhua Ma, Xuyue Pan, Huan Liang, Junde Wu, Zhaojun Chen.
      Gouty arthritis (GA), as a multifactorial disease, is characterised by intense pain, active inflammation symptoms, and swollen joints. It has utterly complex pathogenesis, of which the amount of research publications on GA has increased during the last few decades. A bibliometric analysis was carried out to investigate the trends, frontiers, and hot spots in global scientific output in GA research over the last decade. We retrieved the Science Citation Index Expanded (SCI-Expanded) of the Web of Science Core Collection (WoSCC) for publications and recorded information published from 2012 to 2021. we carried out the bibliometric analysis and visualisation analysis of the overall distribution of annual outputs, leading countries, active institutions, journals, authors, co-cited references, and keywords with the VOSviewer and CiteSpace. The impact and quality of papers were assessed using a global citation score (GCS). We retrieved 2052 articles and reviews in total. The annual number of publications (Np) related to GA research has increased during the latest decade. China published the most papers, and the USA achieved the highest H-index and number of citations (Nc). The League of European Research Universities (LERU) and Clinical Rheumatology (Clin Rheumatol) are the most productive institutions and periodicals. The total GCS of the paper written by Kottgen, A. in 2013 was 479, ranking the first. The most common keywords were "Gout," "hyperuricemia," and "gouty arthritis." This research revealed that though there was a slight fluctuation in publications related to GA, the Np raised on the whole. China was an enormous creator, and the USA was an influential nation in this domain. The top three contributor authors were Dalbeth, N., Singh, JA., and Choi, HK. There were few investigations on the treatment of GA by Chinese medicine monomer, and the "mechanism," "pathway", "nf- kappa-b", "injury", "receptor", and "animal model" were growing research hotspots. Our research illustrated the hotspots of research and development trends in the research field of GA during the last decade. Recognition of the most critical indicators (researchers, countries, institutes, and journals for the release of GA research), hotspots in the research field of GA can be helpful for countries, scholars, and policymakers in this field to understand GA better make decisions.

    Research Trends in Immune Checkpoint Blockade for Melanoma: Visualization and Bibliometric Analysis.
    Yantao Xu, Zixi Jiang, Xinwei Kuang, Xiang Chen, Hong Liu.
      BACKGROUND: Melanoma is one of the most life-threatening skin cancers; immune checkpoint blockade is widely used in the treatment of melanoma because of its remarkable efficacy.OBJECTIVE: This study aimed to conduct a comprehensive bibliometric analysis of research conducted in recent decades on immune checkpoint blockade for melanoma, while exploring research trends and public interest in this topic.
    METHODS: We summarized the articles in the Web of Science Core Collection on immune checkpoint blockade for melanoma in each year from 1999 to 2020. The R package bibliometrix was used for data extraction and visualization of the distribution of publication year and the top 10 core authors. Keyword citation burst analysis and cocitation networks were calculated with CiteSpace. A Gunn online world map was used to evaluate distribution by country and region. Ranking was performed using the Standard Competition Ranking method. Coauthorship analysis and co-occurrence were analyzed and visualized with VOSviewer.
    RESULTS: After removing duplicates, a total of 9169 publications were included. The distribution of publications by year showed that the number of publications rose sharply from 2015 onwards and either reached a peak in 2020 or has yet to reach a peak. The geographical distribution indicated that there was a large gap between the number of publications in the United States and other countries. The coauthorship analysis showed that the 149 top institutions were grouped into 8 clusters, each covering approximately a single country, suggesting that international cooperation among institutions should be strengthened. The core author extraction revealed changes in the most prolific authors. The keyword analysis revealed clustering and top citation bursts. The cocitation analysis of references from 2010 to 2020 revealed the number of citations and the centrality of the top articles.
    CONCLUSIONS: This study revealed trends in research and public interest in immune checkpoint blockade for melanoma. Our findings suggest that the field is growing rapidly, has several core authors, and that the United States is taking the lead position. Moreover, cooperation between countries should be strengthened, and future research hot spots might focus on deeper exploration of drug mechanisms, prediction of treatment efficacy, prediction of adverse events, and new modes of administration, such as combination therapy, which may pave the way for further research.

    Scientific Publications on Thyroid Ultrasound between 2001 and 2020: Differences in Research Characteristics by Disciplines.
    Won Chul Shin, Chae Woon Lee, Jiyeon Ha, Kyoung Ja Lim, Young Lan Seo, Eun Joo Yun, Dae Young Yoon.
      OBJECTIVE: To analyze the characteristics and trends of scientific publications on thyroid ultrasound (US) from 2001 to 2020, specifically examining the differences among disciplines.MATERIALS AND METHODS: The MEDLINE database was searched for scientific articles on thyroid US published between 2001 and 2020 using the PubMed online service. The evaluated parameters included year of publication, type of document, topic, funding, first author's specialty, journal name, subject category, impact factor, and quartile ranking of the publishing journal, country, and language. Relationships between the first author's specialty (radiology, internal medicine, surgery, otorhinolaryngology, and miscellaneous) and other parameters were analyzed.
    RESULTS: A total of 2917 thyroid US publications were published between 2001 and 2020, which followed an exponential growth pattern, with an annual growth rate of 11.6%. Radiology produced the most publications (n = 1290, 44.2%), followed by internal medicine (n = 716, 24.5%), surgery (n = 409, 14.0%), and otorhinolaryngology (n = 171, 5.9%). Otorhinolaryngology and internal medicine published significantly more case reports than radiology (p < 0.001, each). Radiology published a significantly higher proportion of publications on imaging diagnosis (p < 0.001 for all) and a significantly lower proportion of publications on biopsy (p < 0.001 for all) than the other disciplines. Publications produced by radiology authors were less frequently published in Q1 journals than those from other disciplines (p < 0.005 for internal medicine and miscellaneous disciplines and < 0.01 for surgery and otorhinolaryngology). China contributed the greatest number of publications (n = 622, 21.3%), followed by South Korea (n = 478, 16.4%) and the United States (n = 468, 16.0%).
    CONCLUSION: Radiology produced the most publications for thyroid US than any other discipline. Radiology authors published more notably on imaging diagnosis compared to other topics and in journals with lower impact factors compared to authors in other disciplines.

    Knowledge Mapping of Necroptosis From 2012 to 2021: A Bibliometric Analysis.
    Jie Zhang, Luxia Song, Jundi Jia, Wende Tian, Runmin Lai, Zihao Zhang, Jingen Li, Jianqing Ju, Hao Xu.
      Background: Necroptosis, a recently discovered programmed cell death, has been pathologically linked to various diseases and is thus a promising target for treating diseases. However, a comprehensive and objective report on the current status of entire necroptosis research is lacking. Therefore, this study aims to conduct a bibliometric analysis to quantify and identify the status quo and trending issues of necroptosis research in the last decade.Methods: Articles were acquired from the Web of Science Core Collection database. We used two bibliometric tools (CiteSpace and VOSviewer) to quantify and identify the individual impact and cooperation information by analyzing annual publications, journals, co-cited journals, countries/regions, institutions, authors, and co-cited authors. Afterwards, we identified the trending research areas of necroptosis by analyzing the co-occurrence and burst of keywords and co-cited references.
    Results: From 2012 to 2021, a total of 3,111 research articles on necroptosis were published in 786 academic journals by 19,687 authors in 885 institutions from 82 countries/regions. The majority of publications were from China and the United States, of which the United States maintained the dominant position in necroptosis research; meanwhile, the Chinese Academy of Sciences and Ghent University were the most active institutions. Peter Vandenabeele published the most papers, while Alexei Degterev had the most co-citations. Cell Death & Disease published the most papers on necroptosis, while Cell was the top 1 co-cited journal, and the major area of these publications was molecular, biology, and immunology. High-frequency keywords mainly included those that are molecularly related (MLKL, TNF-alpha, NF-κB, RIPK3, RIPK1), pathological process related (cell-death, apoptosis, necroptosis, necrosis, inflammation), and disease related (cancer, ischemia/reperfusion injury, infection, carcinoma, Alzheimer's disease).
    Conclusion: Necroptosis research had a stable stepwise growth in the past decade. Current necroptosis studies focused on its cross-talk with other types of cell death, potential applications in disease treatment, and further mechanisms. Among them, the synergy with ferroptosis, further RIPK1/RIPK3/MLKL studies, its association with inflammation and oxidative stress and translational applications, and the therapeutic potential to treat cancer and neurodegenerative diseases are the trending research area. These might provide ideas for further research in the necroptosis field.

      Background: Tendinopathy is a disabling musculoskeletal disorder affecting the athletics and general populations. There have been increased studies using stem cells in treating tendon diseases. The aim of this bibliometric and visualized study is to comprehensively investigate the current status and global trends of research in tendon stem cells.Methods: Publications related to tendon stem cells from 1991 to 2020 were retrieved from Web of Science and then indexed using a bibliometric methodology. VOSviewer software was used to conduct the visualized study, including coauthorship, cocitation, and cooccurrence analysis and to analyze the publication trends of research in tendon stem cells.
    Results: In total, 2492 articles were included and the number of publications increased annually worldwide. The United States made the largest contribution to this field, with the most publications (938 papers, 37.64%), citation frequency (68,195 times), and the highest H-index (103). The most contributive institutions were University of Pittsburgh (96 papers), Zhejiang University (70 papers), Shanghai Jiao Tong University, and Chinese University of Hong Kong (both 64 papers). The Journal of Orthopaedic Research published the most relative articles. Studies could be classified into five clusters: "Animal study," "Tissue engineering," "Clinical study," "Mechanism research," and "Stem cells research", which show a balanced development trend.
    Conclusion: Publications on tendon stem cells may reached a platform based on current global trends. According to the inherent changes of hotspots in each cluster and the possibilities of cross-research, the research in tendon stem cells may exist a balanced development trend.

    Evaluation of the Relative Citation Ratio Among Academic Orthopedic Hand Surgeons: A Novel Measure of Research Impact.
    John K McNamara, Matthew N Henderson, Suleiman Y Sudah, Robert D Faccone, Christopher R Michel, Christopher Dijanic, Mariano E Menendez, Jeremy B Ruskin.
      Background: Publication metrics such as article citation count and the Hirsch index (h-index) are used to evaluate research productivity among academic faculty. However, these bibliometric indices are not field-normalized and yield inaccurate cross-specialty comparisons. We evaluate the use of the relative citation ratio (RCR), a new field-normalized article-level metric developed by the National Institutes of Health (NIH), among academic orthopedic hand surgeons and analyze physician factors associated with RCR values. Methods: A retrospective analysis was performed using the iCite database. Fellowship-trained orthopedic hand surgeons affiliated with accredited orthopedic surgery residency programs were included. Mean RCR, weighted RCR, and publication count were compared by sex, career duration, academic rank, and presence of additional degrees. Mean RCR represents the total number of citations per year of a publication divided by the average number of citations per year received by NIH-funded papers in the same field. Mean RCR serves as a measure of overall research impact. A value of 1.0 is the NIH-funded field-normalized standard. Weighted RCR is the sum of all article-level RCR scores and represents overall research productivity. Results: A total of 620 academic orthopedic hand surgeons from 164 programs were included. These physicians produced highly impactful research with a median RCR of 1.27 (interquartile range [IQR] 0.86-1.66). Weighted RCR was associated with advanced degree, advanced academic rank, and longer career duration. Conclusions: Fellowship-trained academic orthopedic hand surgeons produce highly impactful research. Our benchmark data can be used to assess grant outcomes, promotion, and continued evaluation of research productivity within the hand surgery community.

    Xingrong Guo.
      This study purposed to provide a bibliometric overview of child language (CL) research from 1900 to 2021 and identify major trends in CL. A total of 48,453 research articles related to the CL were identified from the Web of Science. Co-authorship, co-word, and co-citation analysis was conducted by using VOSviewer and CiteSpace. The following was analyzed: annual distribution of related papers; related disciplines; mainstream journals; geographical and institutional distribution; hot topics; keyword burst detection; and co-citation analysis of journals, authors, and references. Results showed that, under the impact of new empirical methods and new theories, the field of CL is undergoing great changes. Research hotspot and the research trends mainly concentrated on autism spectrum disorder, school readiness, oral language, reading comprehension, exposure, bilingualism, vocabulary, input, skills, kindergarten, cochlear implants, and intervention. More and more pieces of research focus on the individual difference in CL development and the importance of intervention in language education by typically developing children and some children with disabilities or language disorders. Besides, child second language acquisition also attracted a lot of attention. This bibliometric analysis is of great reference significance for researchers to understand the progress and discipline development trend in this field.

      Background: Schizophrenia (SCZ) is a severe psychiatric disorder that involves inflammatory processes. The aim of this study was to explore the field of inflammation-related research in SCZ from a bibliometric perspective.Methods: Regular and review articles on SCZ- and inflammation-related research were obtained from the Web of Science Core Collection (WOSCC) database from its inception to February 19, 2022. R package "bibliometrix" was used to summarize the main findings, count the occurrences of the top keywords, visualize the collaboration network between countries, and generate a three-field plot. VOSviewer software was applied to conduct both co-authorship and co-occurrence analyses. CiteSpace was used to identify the top references and keywords with the strongest citation burst.
    Results: A total of 3,596 publications on SCZ and inflammation were included. Publications were mainly from the USA, China, and Germany. The highest number of publications was found in a list of relevant journals. Apart from "schizophrenia" and "inflammatory", the terms "bipolar disorder," "brain," and "meta-analysis" were also the most frequently used keywords.
    Conclusions: This bibliometric study mapped out a fundamental knowledge structure consisting of countries, institutions, authors, journals, and articles in the research field of SCZ and inflammation over the past 30 years. The results provide a comprehensive perspective about the wider landscape of this research area.

    Zitong Li, Haoran Ke, Qianyun Lin, Zefeng Shen, Ye Chen.
      BACKGROUND: Clostridioides (clostridium) difficile infection (CDI) is the most common cause of nosocomial diarrheal disease, which has become a public health problem worldwide; gut dysbiosis plays a central role in its pathophysiology. This study conducted a bibliometric analysis of publications on gut microbiota and CDI to summarize the current status of research including research hotspots.METHODS: Relevant publications from January 2004 to February 2022 were identified from the Web of Science Core Collection. Three bibliometric tools were used to perform visualization analyses.
    RESULTS: A total of 1983 publications were analyzed. Annual publications increased from 11 in 2004-237 in 2021, with the US being the leading producer (47.55 % of all papers). EG Pamer had the highest average citations per article (average citations per item = 153.03, H-index = 29). Frontiers in Microbiology published the most papers. The main research foci were "fecal microbiota transplantation," "colonization resistance," and "multidrug-resistant bacteria." The keywords with the highest frequency in recent years include: gut dysbiosis, antibiotic resistance, bile-acids, 16 s sequencing, multidrug-resistant bacteria, and short chain fatty acids.
    CONCLUSIONS: Gut microbiota and CDI is likely to remain a prominent area of research in the foreseeable future. Current research hotspots ("fecal microbiota transplantation," "colonization resistance," and "multidrug-resistant bacteria") should receive even more attention in future studies.

    The professional network underlying cerebral palsy intervention research based on systematic reviews and meta-analyses published in international journals: authors' communities, institutional networks, and international collaboration.
    Henriett Pintér, Franciska Gál, Pál Molnár.
      Cerebral palsy (CP) is a well-researched area of medical science, health science and special education. The growing number of publications every year makes difficult to monitor the progress of this research domain, therefore there is a broad interest for conducting systematic reviews and meta-analyses of interventions in international peer-reviewed scientific journals. Our goal is to analyze the scientific activity of authors who published systematic reviews and meta-analyses of CP intervention studies. To identify the active researchers, institutions, and countries, we used scientometric and bibliometric indicators that assess their productivity, collaborations, and the citations (utilization/usefulness of their studies), also paying attention to the institutional background and the network structure of national and international collaboration. We used Scopus to search for articles and included systematic reviews and meta-analyses of intervention studies, a total of 180 works, in our sample. Our results showed active and large communities of prolific authors and groups of authors with diverse institutional background. Most institutions are universities, hospitals, but we found various other organizations among them. Most of the universities are leading educational institutions according to international rankings; some of them are among the top-ranking ones. In geographical terms, the North American, Australian, and European regions are the most active and most interconnected ones. We assume organizations other than scientific collaboration networks also play a major role in the productivity and dissemination of scientific knowledge in this research area. As an example, we could mention the network, including the US, Australian and European registers. Authors living and working in the Far East, the Middle East or in South America also started to publish relevant articles in the 2010s. The research network structuring scientific knowledge in this area is flourishing.

    Stem Cell Therapy for Neuropathic Pain: A Bibliometric and Visual Analysis.
    Houming Kan, Lijun Fan, Xiaodie Gui, Xiaoqiang Li, Sen Yang, Yuting Huang, Liping Chen, Wen Shen.
      Purpose: Neuropathic pain is intractable and current treatment modalities are ineffective to cure this intractable pain, which has become a global problem. In recent years, there have been an increasing number of studies on stem cell therapy for neuropathic pain that have shown enormous potential. Using a visual analysis approach of the existing literature on stem cell therapy for neuropathic pain, we hope to understand the current research status and hot issues in this field and to provide valuable predictions for future research in this field.Methods: We used Citespace software to visually analyze 291 articles and reviews indexed by the Web of Science Core Collection Database exploring stem cell-based treatment of neuropathic pain from 1995 to 2021. The Gunnmap online world map evaluated the number of countries and regional articles separately. Microsoft Excel 2016 was used to generate a graph of trends in annual publications.
    Results: Visualization analysis revealed that the number of publications has increased yearly. The top three countries in terms of number of articles published are United States, China, and Japan. Analysis of highly co-cited articles revealed that the contents of these articles primarily involved the expression of IL-1β, IL-10, NPY, TRPA1, p-p38, p-ERK1/2, TGF-β, PKCδ, CaMKIIɑ, P2X4, P2X7 and TNF-ɑ. Keywords and citation burst analysis demonstrated that activation, regeneration, chemotherapy, and expression are likely the research hotspots and future directions of stem cell research in neuropathic pain.
    Conclusion: Stem cell therapy may be a potential means of future treatment of neuropathic pain. The study of the mechanisms underlying stem cell therapy for neuropathic pain is still a focus of future research.

    Knowledge Mapping of Olfactory Dysfunction: A Bibliometric Study.
    Wen Hu, Na Chen, Weiheng Yan, Pei Pei, Yongxiang Wei, Xiaojun Zhan.
      Background: Olfaction is one of the five basic senses of human beings. As such, olfactory dysfunction seriously affects patients' quality of life and can even endanger them. In recent years, olfactory dysfunction has attracted greater research interest, and numerous studies have been published on olfactory dysfunction. However, there are few studies on olfactory dysfunction through bibliometric analysis. This study aims to describe the current situation and identify the foci and potential new research directions of olfactory dysfunction using a bibliometric approach.Methods: Articles related to olfactory dysfunction published from 2002 to 2021 were located in the Web of Science Core Collection of Clarivate Analytics (London, UK). Bibliometric analyses were conducted with the CiteSpace (Chaomei Chen, Drexel University, Philadelphia, PA, USA) and VOSviewer (Center for Science and Technology Studies, Leiden University, Leiden, Netherlands) software programs.
    Results: The number of articles published each year showed an upward trend, especially in 2020, where a sharp increase had occurred due to the coronavirus disease 2019 (COVID-19) pandemic. The United States was the country with the most publications and the strongest international cooperation. In terms of institutions, the greatest number of publications from a single institution came from Dresden University of Technology. Thomas Hummel was the author who had contributed the most articles. An analysis of co-citation networks and burst keywords in the field revealed a shift from "gonadotropin-releasing hormone" and "apoptosis" earlier on to "olfactory training," "COVID-19," and "Parkinson's disease" more recently. "Outcome," "COVID-19," "infection," and "pathogenesis" are topics of the research frontier and hotspots.
    Conclusion: More attention has been paid to olfactory dysfunction as the understanding of it has improved in the past 20 years. This study provides researchers with an objective, systematic, and comprehensive analysis of the literature on olfactory dysfunction. The current frontier areas and hotspots in the field focus on the pathological mechanisms of olfactory dysfunction after infection with COVID-19 and its different prognoses. The pathophysiological mechanism of olfactory dysfunction in neurodegenerative diseases and COVID-19 will be a primary future research direction.

    Global research trends of immunotherapy and biotherapy for inflammatory bowel disease: a bibliometric analysis from 2002 to 2021.
    Jia-Qi Xiong, Yun-Feng Fu, Jian-Hao Qiu, Wang-Di Liao, Ling-Yu Luo, Si-Hai Chen.
      BACKGROUND: It is known that inflammatory bowel disease is the result of a defective immune system, and immunotherapy and biological therapy have gradually become important means to treat it. This paper focused on the bibliometric statistical analysis of the current research progress to summarize the research status of this field and analyze the research trends in recent years.METHODS: Two visualization tools, CiteSpace and VOSviewer, were used to explore the data of journals, institutions, countries/regions, authors, references, and keywords for the literature included in the Web of Science Core Collection from January 1, 2002, to December 31, 2021.
    RESULTS: A total of 312 papers were published in 120 journals by 603 institutions from 40 countries/regions, with 9463 co-cited references. The United States has the most publications with the highest total citations in the world. Inflammatory Bowel Diseases published the maximum number of papers, and Gastroenterology devoted the most co-citations to immunotherapy and biological therapy for IBD. In addition, we found that the studies before 2009 mostly focused on clinical trials while researchers have paid more attention to clinical management in therapy for IBD since 2009. Combination therapy and management of the treatment for the disease have become research hotspots.
    CONCLUSION: The focus of immunotherapy and biotherapy for IBD has shifted from clinical trials to the management of the risks and benefits of immunotherapy.

    Visualization of scientific collaboration and themes for arbovirus disease in the caribbean: A forty-year trend analysis with focus on dengue, Zika and Chikungunya.
    Cédric Contaret, Raymond Césaire, Jacqueline Deloumeaux, Clarisse Joachim, André Cabié, Moustapha Dramé.
      BACKGROUND: The (re-)emergence of arboviruses in the Caribbean, and worldwide, is a major public health issue of concern to all scientific research stakeholders. This study aimed to use bibliometric analysis to identify the contribution of Caribbean countries to scientific production regarding the three arboviruses with the greatest impact, namely zika, chikungunya and dengue.METHOD: Bibliographic data related to arbovirus diseases were collected from three international databases (Web of Science, Pubmed, and Scopus), filtered by Caribbean islands of affiliation. VosViewer was used to identify scientific connections between countries or institutions and to identify research themes.
    RESULTS: The dataset comprised 1332 indexed articles, with 50% of articles categorized in the top quartile of quality. Cuba was found to lead research on dengue, with a total of 300 articles, and 18 international connections. The USA-Puerto Rico duo was found to be the leader on emerging arboviruses (Zika and Chikungunya), followed by a predominantly French-language cluster (mainland France, Guadeloupe, Martinique). Key research topics were related to clinical presentations, epidemiology, and research on mosquito-borne viruses CONCLUSIONS: Co-authorship network analysis on emerging arboviruses revealed the dynamics of collaboration, and provides insights into Caribbean collaborations that deserve to be created and consolidated in case of resurgence of new arbovirus epidemics.

    A bibliometric analysis of global research performance on tuberculosis (2011-2020): Time for a global approach to support high-burden countries.
    Muhammad Abdullah, Ayesha Humayun, Muhammad Imran, Muhammad A Bashir, Ahmad A Malik.
      BACKGROUND: Tuberculosis (TB) is a persistent public health issue requiring consistent global effort for its eradication and control. Research on the subject plays a vital role in combatting the disease, giving future directions, and meeting the sustainable development goals (SDGs). This study aimed to evaluate the global TB research trends and performance from 2011 to 2020.MATERIALS AND METHODS: All the data for TB-related research publications from 2011 to 2020 were extracted from the Web of Science database and a comprehensive analysis was performed on the R-bibliometrix package.
    RESULTS: An increasing number of publications with an annual growth rate of 6.32% and a plateau in production from 2015 to 2018 was observed. Of 145 countries, the United States of America (USA), China, India, the United Kingdom, and South Africa led and made up half of the global contribution. Out of 91,862 authors, Zhang Y was the most productive with 205 articles and Barry CE had the highest H-index of 45. Only seven of the top 20 authors were from high-burden countries. The University of Cape Town was the leading institutional affiliation, followed by Stellenbosch University and the London School of Hygiene and Tropical Medicine. The most frequent international collaboration was between the USA and South Africa, occurring on 1203 instances. Only five of the top 30 high-burden countries were present in the top 30 collaborations. PLOS ONE, disseminating 2271 articles, was the most productive out of 3500 sources.
    CONCLUSION: The past decade has seen a steady increase in global TB research. Prominent authors, affiliations, and countries showed collaborative trends, but publications were found to be mostly from developed, low-burden countries except China, India, and South Africa. To meet the goals set by the SDGs and the WHO End TB Strategy, high-burden countries need to explore feasible opportunities and global support to enhance their expected TB-related research contributions.

    Trends in Orthopaedic Foot and Ankle Publications.
    Brian Sleasman, Caroline Chen, Alex M Caughman, Caroline Hoch, Daniel Scott, Christopher E Gross.
      Background: Scientific publication and original articles remain the primary method of sharing scientific findings and advancing the knowledge base of that subject. Despite the value of these publications, little research has surveyed what topics are being published. This study aims to identify and characterize the most common topics in current foot and ankle literature.Methods: We reviewed all 1514 published articles in a 5.5-year period (January 2014-June 2019) in 2 foot and ankle-specific journals: Foot & Ankle International (FAI) and Foot and Ankle Surgery (FAS). The articles were sorted into different topic domains to identify the 3 most common categories of publication. The top 3 domains were further characterized by level of evidence (LOE) as well as citations.
    Results: The 3 most published topics in foot and ankle literature were hallux valgus (8.3%), total ankle arthroplasty (TAA) (8.3%), and ankle fracture (6.6%). These 3 subjects accounted for 351 articles (23.2%). Other common topics were patient-reported outcomes (5.0%), osteochondritis dissecans (3.9%), syndesmotic injury (3.8%), ankle instability (3.7%), hallux rigidus (3.0%), and anatomy (2.8%). The average LOE for articles on hallux valgus, TAA, and ankle fracture was 3.27 from FAI, and the average number of annual citations for a given article in both journals was 3.05. Based on our study, there is no correlation between LOE and number of overall citations, but there is a significant, negative linear correlation in ankle fracture data. We also found that articles on TAA had the highest impact factor and that articles from FAI were cited more often than articles from FAS.
    Conclusion: The 3 most published topics in foot and ankle literature comprise only 23.2% of all articles. This finding is indicative of the wide variety of cases performed by orthopaedic foot and ankle surgeons. High-quality data are still needed in all topics.
    Level of Evidence: Level III, retrospective cohort study.

    Yue Wang, Zhao Wang, Guoqing Liu, Zhangyi Wang, Qinglong Wang, Yishan Yan, Jing Wang, Yue Zhu, Weijie Gao, Xiangling Kan, Zhiguo Zhang, Lixia Jia, Xiaoli Pang.
      Background: Serious games (SGs) as one kind of intervention that can improve the level of knowledge and change behavior to affect health outcomes has been increasingly applied in health care.Objective: Analyze hotspots and trends of the application of SGs in health care and provide reference and direction for further research in the future.
    Methods: The Web of Science (WoS) Core Collection database was used for extracting the literature on SGs in health care for the period from the database established to 11 October, 2021. Scoping review and bibliometric analysis were used to deeply analyze and visualize countries, categories of studies, annual study output, cited authors, cited journals, cited articles, and keywords of healthcare field.
    Results: A total of 1,322 articles were retrieved, then every articles' title and abstract were read one by one, and 795 articles were included after screening with an exponential increase in publication volume. The United States of America made the greatest contribution to global publications regarding SGs in health care. From the total, 20.8% of articles fall under the category of health care sciences services. The target groups were mainly concentrated in children (18.0%), youth (13.8%), the elderly (10.9%), adolescents (9.1%), and adults (3.4%). Baranowski T (n = 103 citations) is the most influential author, followed by Kato PM (n = 73 citations) and Desmet A (n = 58 citations). The top three cited journals were "Plos One" (n = 268 citations), "Games for Health Journal" (n = 209 citations), and "Journal of Medical Internet Research" (n = 197 citations), and the top three cited articles were "A meta-analysis of serious digital games for healthy lifestyle promotion," "A Systematic Review of Serious Games in Training Health Care Professionals," and "Video game training enhances cognitive control in older adults." More and more studies focus on specific age groups, such as children, adolescents, and the elderly. The research hotspots and trends included "rehabilitation," "medical education," and "design."
    Conclusions: The application of SGs in health care remains important areas for future research. "Rehabilitation," "medical education," and "design" reflected the latest research hotpots and future trends.

    Scientific production on silicate-based endodontic materials: evolution and current state: a bibliometric analysis.
    Julia Guerrero-Gironés, Leopoldo Forner, José Luis Sanz, Francisco Javier Rodríguez-Lozano, James Ghilotti, Carmen Llena, Adrián Lozano, María Melo.
      OBJECTIVES: To perform a bibliometric analysis on silicate-based biomaterials in endodontics; to elucidate the evolution and distribution of scientific production regarding research on these biomaterials, the authors and institutions involved, and the most used descriptors/keywords in this field.MATERIALS AND METHODS: A general advanced broad search was performed in Web of Science Core Collection, using the terms "Silicate" and "Endod*." By means of the "Analyze Results" and "Citation Analysis" tools from Web of Science, bibliometric data were extracted. Bibliometric networks on co-authorship and keyword co-occurrence were illustrated using VOSviewer software tool.
    RESULTS: Research in the field of silicate-based endodontic materials in endodontics has followed an exponential crescent tendency over the period between 1995 and 2020. Two major co-authorship networks lead the research production in the field, headed by Gandolfi MG and Prati C, and Rodríguez-Lozano FJ and Forner L; respectively. "Mineral trioxide aggregate," "MTA", "Biocompatibility," "Biodentine," and "In vitro" were the terms with the highest occurrence. The modal study type in this research area are laboratory studies, representing 77.7% of the total number of records. The relationship between keywords illustrates the recent tendency to assess biological properties of MTA and Biodentine, which could be extrapolated to other silicate-based materials.
    CONCLUSIONS: The results from the present study highlight the exponential increase and distribution of scientific production on silicate-based materials in endodontics, along with the modal keywords used as descriptors and the major authorship networks involved. The predominance of laboratory studies in this research field reinforces the need for clinical studies, to extrapolate the reported performance and characteristics of silicate-based materials into the clinical setting.
    CLINICAL RELEVANCE: The present study may aid the clinician's continuing education and evidence-based practice by providing knowledge and facilitating the literature search on the field of silicate-based biomaterials in endodontics.

    Scientometric analysis and identification of research trends in microplastic research for 2011-2019.
    Deepika Sharma, Shreya Jaiswal, Gurjot Kaur.
      Microplastic pollution of our environment has seen major data reporting in the last decade. Microplastics produce harmful effects on marine organisms and in humans. Despite the fact that microplastics (MPs) have inert or sublethal toxicity in many circumstances, their long-term presence can have negative ecological consequences. However, there is a paucity of comprehensive literature on the present study and future development trend of MPs in aquatic ecosystems, to our knowledge. In this scientometric study, the literature was evaluated between years 2011 and 2019. The data show increasing importance of microplastics in terms of increase in publication in concurrence of granting funds in this area by major funding agencies. Most research articles were published by authors (~ 49%) affiliated with Chinese Academy of Sciences. Journals 'Marine Pollution Bulletin' and 'Environmental Pollution' were identified as important journals with 273 and 185 research publications, respectively. We have also identified the upcoming research trend and shift from microplastic presence in water to microplastic presence in air. However, in the year 2017, researchers from the UK started publishing more articles in this field with 11 publications with top authors affiliated to University of Plymouth. The journal Environmental Pollution has been found to be the leading journal (~ 20%) addressing the issue of microplastics in the environment. Our co-authorship analysis demonstrated that China (its institutions and authors) is the most collaborative country followed by the USA, together forming top cluster with a link strength of 42. Finally, our analysis provides information about prospective research and emerging trends that can be explored in the coming years.

    A Bibliometric Analysis of the 50 Most Commonly Cited Studies of the Direct Anterior Approach in Total Hip Arthroplasty.
    Ramakanth R Yakkanti, Anil Sedani, Dylan N Greif, Rukmini Yakkanti, Dustin H Massel, Victor H Hernandez.
      Introduction: The direct anterior approach (DAA) has garnered a lot of attention and surgical popularity for total hip arthroplasty in recent years. Some of the postulated advantages for the increase in popularity of this approach include better pain control and earlier recovery in the immediate postoperative period. The amount of literature available on this topic has rapidly increased over the last 10 years requiring the need for an updated guide to best navigate the topic.Methods: The ISI Web of Knowledge database was used to search for research articles regarding the DAA surgical technique. The Boolean operative that yielded the largest search results was ([direct anterior approach hip] OR [anterior hip] OR [anterior hip arthroplasty] NOT [spine]).
    Results: 92% of the highest cited articles on the DAA were published within the past two decades. One author, Keggi K, published 4 or more articles, with the highest citation average (110.5 citations). Recent articles were more strongly correlated with higher citation counts (R 2 = 0.21 v. 0.19).
    Conclusion: This review clearly outlines the increasing trend in the most influential publications regarding DAA being published in the past two decades. This review allows interested surgeons to understand the historic literature pertaining to this topic. This review can assist future researchers in identifying trends in UKA as well as help clinicians navigate this body of literature.

    A systematic method for identifying references to academic research in grey literature.
    Matthew S Bickley, Kayvan Kousha, Michael Thelwall.
      Grey literature encompasses documents not published in academic journals or books. Some grey literature has substantial societal importance, such as medical guidelines, government analyses and pressure group reports. Academic research cited in such documents may therefore have had indirect societal impact, such as in policy making, clinical practice or legislation. Identifying citations to academic research from grey literature may therefore help assess its societal impacts. This is difficult, however, due to the variety of document and referencing formats used in grey literature, even from a single organisation. In response, this study introduces and tests a semi-automatic method to match academic journal articles with unstandardised grey literature cited references. For this, the metadata (lead author last name, title, year) of 2.45 million UK Russell Group university outputs was matched against a 100-document sample of UK government grey literature to assess the accuracy of 21 matching heuristics. The optimal method (lead author last name and title in either order, maximum of 200 characters apart) is sufficiently accurate and scalable to make the task of matching research outputs to grey literature references feasible. The method was then applied to 3347 government publications, showing approximately 23% of UK government grey literature in this study contained at least one reference to UK Russell Group university output, and of this grey literature, an average of 3.79 references were present per document. The applied method also shows that economics and environmental science academic research is most cited between 2010 and 2018.Supplementary Information: The online version contains supplementary material available at 10.1007/s11192-022-04408-4.

    Publication activity in water treatments: Web of Science-based bibliometric analysis of the last two decades.
    Fulya Demircioğlu Güneri, Fatih Karaarslan, Fatma Begüm Erol Forestıer, Romain J Forestıer, Ersin Odabaşı.
      We evaluated the quantity and quality of scientific publications linked with water treatments using the Web of Science (WoS) database. The WoS was searching by using the following terms "hydrotherapy," "balneotherapy," "spa therapy," "spa treatment," "creno-balneotherapy," "water treatments," and "aqua therapy," on February 10th, 2022. The recorded data were the total number of articles, year of articles, country of articles, journal, document type, index data, and citation data. Also, the studies performed with natural source mineral water were marked to make a further subgroup analysis through quality and quantity. We obtained 816 articles; 667 (81.74%) were original research articles, and 149 (18.26%) were review articles. A statistically significant and increasing trend was shown in the publication about water treatments (p < 0.01). About three-quarters of the trials were sourced from high-income countries. Italy (n = 98; 12.01%); Turkey (n = 75; 9.19%); Australia (n = 65; 7.97%); Brazil (n = 46; 5.64%); and France (n = 38; 4.66%) were the most productive countries. Calculating the number of articles per million population, Hungary (3.38), Australia (2.53), and Italy (1.64) ranked in the top three. According to 100 billion dollars GDP, the top three countries were Brazil (24.41), Hungary (21.15), and Turkey (10.41). In the average citation calculation, the Netherlands (60.84), Israel (29.86), and Australia (29.06) were in the top three. The International Journal of Biometeorology was the leading journal for publication trials about water treatments. In the subgroup analysis, we found the total number of studies performed with natural source mineral water and non-specified source water trials as 430 and 386, respectively. We also presented that the natural source and non-specified water trials had a statistically significant and increasing trend between 2000 and 2021 (p < 0.01 and p < 0.01, respectively). The trials performed with natural source water mainly were sourced from Italy (n = 79; 18.37%), Turkey (n = 61; 14.19%), France (n = 38; 8.84%), Poland (n = 30; 6.98%), and Hungary (n = 29; 6.74%), the trials performed with non-specified water were sourced from Australia (n = 61; 15.80%), Brazil (n = 46; 11.92%), USA (n = 27; 6.99%), Italy (n = 19; 4.92%), and England (n = 18; 4.66%). The top journal of the natural source water trials was the International Journal of Biometeorology (n = 65; 15.12%), and for the non-specified water trials, it was the International Journal of Sports Physiology (n = 12; 3.11%).Our study presented an increasing trend in trial publications regarding water treatments between 2000 and 2021. Most of the trials were from high and upper-middle-income countries. We suggest that by demonstrating global productivity worldwide, our results can create more scientific attention on this topic and may promote the quantity and quality of the trials.

    Christiana S Renner, Andrew Sumarsono, Achsah Mathew, Maryam Warsi, Usman Niaz, Vivek Patel, Eugene S Chu.
      BACKGROUND: Scholarship remains the principal currency for faculty promotion in academic medicine. Reference points for scholarly growth and productivity at academic medical centers (AMCs) are lacking.METHODS: We identified hospital medicine full professors (HMFPs) at AMCs ranked in research by US News & World Report. Scopus was used to identify each HMFP's publications, citations, and Hirsch-index (H-index). Publications; citations; and first, middle, and senior author papers were measured in 3-year intervals postresidency. Scholarly productivity was analyzed by quintile based on publications, AMC research ranking, years postresidency, and grant funding.
    RESULTS: Data were extracted for 128 HMFPs from 54 AMCs. HMFPs were a mean of 20.5 (SD: 5.4) years postresidency. The median H-index was 7.0 (interquartile range [IQR]: 2.0-16.0); the median number of publications was 15.0 (IQR: 4.0-51.0). Top quintile HMFPs had a median of 175.5 (IQR: 101.5-248.0) publications, whereas fifth quintile HMFPs had a median of 0.0 (IQR: 0.0-1.0) (p < .001). HMFPs on faculty at the top 20 AMCs had a median of 35.5 (IQR: 11.0-108.0) publications, whereas HMFPs in AMCs ranked 81-122 had a median of 3.0 (IQR: 1.0-9.0) (p < .001). Grant-funded HMFPs had a median of 177.0 (IQR: 71.0-278.0) publications, while nongrant-funded HMFPs had a median of 11.0 (IQR: 3.0-25.0) (p < .001). At 3, 6, and 9 years postresidency, HMFPs had a median of 0.0 (IQR: 0.0-1.0), 1.5 (IQR: 0.0-5.0), and 3.5 (IQR: 0.0-11.0) publications. Fellowship training, additional degrees, and top 25 residency programs correlated with the top half of scholarly productivity.
    CONCLUSIONS: Scholarly productivity among HMFPs varies considerably. At 3, 6, and 9 years postresidency, it is minimal to modest. Grant funding and AMC research rank may establish separate frames of reference for scholarly growth.

    Future trends and patterns in leachate biological treatment research from a bibliometric perspective.
    Dhaneswara Ilmasari, Eri Sahabudin, Fatimah Azizah Riyadi, Norhayati Abdullah, Ali Yuzir.
      Leachate has become a great deal of concern due to its complex properties which are primarily caused by the high concentrations of organics and ammonia. Thus, proper leachate treatment is required prior to its discharge. Leachate can be treated in various ways, and biological treatment is one of the approaches. This treatment has been shown to be both effective and cost-efficient while offering the possibility of resource recovery in the form of bioenergy. In this study, the underlying patterns in publications related to leachate biological treatment were uncovered through bibliometric analysis. This study also lays the groundwork for a deeper understanding of the past, current, and future trends of the leachate biological treatment. Research publications from 1974 to 2021 were retrieved from the Scopus database, and it was identified that 2013 articles were published in the span of 47 years. From the analyzed publications, China played a leading role in publishing leachate biological treatment research articles as well as having the most productive institutions and authors. Meanwhile, the USA was found to be the most active country in initiating international collaborations with 33 countries. The research hotspots were also successfully identified using keyword co-occurrences analysis. Anaerobic digestion and constructed wetland were revealed to be the research hotspots. The critical role of biological treatment in removing nitrogen from leachate was also highlighted. Besides, numerous research gaps were identified in the application of aerobic granular sludge (AGS) for leachate treatment. This can be a potential area for research in the future. Finally, future research should be encouraged to focus on the use of sustainable treatment systems in which energy recovery in the form of biogases is promoted.

    Systematic Bibliometric and Visualized Analysis of Research Hotspots and Trends on the Application of Artificial Intelligence in Ophthalmic Disease Diagnosis.
    Junqiang Zhao, Yi Lu, Shaojun Zhu, Keran Li, Qin Jiang, Weihua Yang.
      Background: Artificial intelligence (AI) has been used in the research of ophthalmic disease diagnosis, and it may have an impact on medical and ophthalmic practice in the future. This study explores the general application and research frontier of artificial intelligence in ophthalmic disease detection. Methods: Citation data were downloaded from the Web of Science Core Collection database to evaluate the extent of the application of Artificial intelligence in ophthalmic disease diagnosis in publications from 1 January 2012, to 31 December 2021. This information was analyzed using CiteSpace.5.8. R3 and Vosviewer. Results: A total of 1,498 publications from 95 areas were examined, of which the United States was determined to be the most influential country in this research field. The largest cluster labeled "Brownian motion" was used prior to the application of AI for ophthalmic diagnosis from 2007 to 2017, and was an active topic during this period. The burst keywords in the period from 2020 to 2021 were system, disease, and model. Conclusion: The focus of artificial intelligence research in ophthalmic disease diagnosis has transitioned from the development of AI algorithms and the analysis of abnormal eye physiological structure to the investigation of more mature ophthalmic disease diagnosis systems. However, there is a need for further studies in ophthalmology and computer engineering.

    Dina M El-Sherif, Mohamed Abouzid.
      BACKGROUND: Mobile health applications (mHealth apps) offer enormous promise for illness monitoring and treatment to improve the provided medical care and promote health and wellbeing.OBJECTIVE: We applied bibliometric quantitative analysis and network visualization to highlight research trends and areas of particular interest. We expect by summarizing the trends in mHealth app research, our work will serve as a roadmap for future investigations.
    METHODS: Relevant English publications were extracted from the Scopus database. VOSviewer (version 1.6.17) was used to build coauthorship networks of authors, countries, and the co-occurrence networks of author keywords.
    RESULTS: We analyzed 550 published articles on mHealth apps from 2020 to February 1, 2021. The yearly publications increased from 130 to 390 in 2021. JMIR mHealth and uHealth (33/550, 6.0%), J. Med. Internet Res. (27/550, 4.9%), JMIR Res. Protoc. (22/550, 4.0%) were the widest journals for these publications. The United States has the largest number of publications (143/550, 26.0%), and England ranks second (96/550, 17.5%). The top three productive authors were: Giansanti D., Samuel G., Lucivero F., and Zhang L. Frequent authors' keywords have formed major 4 clusters representing the hot topics in the field: (1) artificial intelligence and telehealthcare; (2) digital contact tracing apps, privacy and security concerns; (3) mHealth apps and mental health; (4) mHealth apps in public health and health promotion.
    CONCLUSIONS: mHealth apps undergo current developments, and they remain hot topics in COVID-19. These findings might be useful in determining future perspectives to improve infectious disease control and present innovative solutions for healthcare.

    The Impact of Academic Publication: Inequity for Women in Behavior Analytic Journals.
    Jennifer M Krebsbach.
      The number of women in higher education has increased over the past few decades but are still not at an equal level to their male counterparts, especially at the tenured level. One area of note within the tenure process is research. This area is highly valued by certain universities and could shed light on discrepancies in the number of female faculty as the faculty position becomes more prestigious. The author downloaded 21 years of publication data for seven prestigious behavior analytic journals and used quantitative methods to determine if the rates of publication differed between a previous study and today. There were 8,778 final articles yielding 27,225 authors in total. Data showed that women are represented more frequently overall, across time and all journals, less frequently in prestigious authorship positions, and more often when the sex of the editor at the time of publication was also female. While women's participation has increased over time, and since the original study, there is still disproportionate representation compared to the entirety of the field, in the order of authorship positions, and for editor-in-chief positions.

    Association of publication record and independent NIH funding.
    Kenneth A Michelson.
      BACKGROUND: Publications may be a modifiable factor toward research project grant (RPG) funding decisions, the objective was to determine the association of publication record with later RPG receipt.METHODS: This was a retrospective cohort study of recipients of K01, K08, or K23 US career development awards (CDAs) starting from 2000-2015. Exposures were CDA awardees' first-, middle-, and last-author publication counts, and the quartile of awardees' highest and mean publication impact factors. The independent association of each exposure with time to RPG (R01 or equivalent) was determined using a Cox model, after adjustment for CDA type, awardee change in institution, and institutional CDA count. The proportion of CDA recipients with later independent funding was also determined by publication count.
    RESULTS: Among 6744 CDA awardees, 3943 obtained an RPG. The median time to RPG was 5.6 years (interquartile range 4.2-7.5). The number of first-authorships was associated with a shorter time to RPG (1-4 versus 0: hazard ratio [HR] 1.22, 95% confidence interval [CI] 1.10-1.36; 5-9: 1.59, 95% CI 1.40-1.79; 10-24: 1.78, 95% CI 1.54-2.07; 25+: 2.40, 95% CI 1.61-3.56). Last-authorships were associated with a shorter time to RPG (1-4 versus 0: HR 1.99, 95% CI 1.83-2.16; 5-9: 2.72, 95% CI 2.45-3.03; 10-24: 3.17, 95% CI 2.78-3.62; 25+: 3.12, 95% CI 2.17-4.50). Higher maximum impact factor was associated with a shorter time to RPG (Q2 versus lowest: HR 1.28, 95% CI 1.12-1.46; Q3: 1.45, 95% CI 1.24-1.70; Q4: 1.67, 95% CI 1.39-2.02). Mean impact factor and middle-authorships were not associated with time to RPG. Among 687 CDAs with zero associated first- or last-authorships, 158 (23%) achieved later RPG funding. Among those with at least 10 total first- or last-authorships, 1288/1554 (83%) obtained a later RPG.
    CONCLUSIONS: A higher number and impact of publications was associated with later independent funding.

    Authorship representation in global emergency medicine: a bibliometric analysis from 2016 to 2020.
    Stephanie Chow Garbern, Gimbo Hyuha, Catalina González Marqués, Noor Baig, Jennifer L Chan, Sanjukta Dutta, Masuma A Gulamhussein, Gloria Paulina López Terán, Hussein Karim Manji, Winnie K Mdundo, Rachel T Moresky, Raya Yusuph Mussa, Erin E Noste, Mulinda Nyirenda, Maxwell Osei-Ampofo, Sindhya Rajeev, Hendry R Sawe, Alphonce Nsabi Simbila, M C Kaushila Thilakasiri, Nikkole Turgeon, Benjamin W Wachira, Rebecca S Yang, Amne Yussuf, Raina Zhang, Alishia Zyer, Chris A Rees.
      INTRODUCTION: High-income country (HIC) authors are disproportionately represented in authorship bylines compared with those affiliated with low and middle-income countries (LMICs) in global health research. An assessment of authorship representation in the global emergency medicine (GEM) literature is lacking but may inform equitable academic collaborations in this relatively new field.METHODS: We conducted a bibliometric analysis of original research articles reporting studies conducted in LMICs from the annual GEM Literature Review from 2016 to 2020. Data extracted included study topic, journal, study country(s) and region, country income classification, author order, country(s) of authors' affiliations and funding sources. We compared the proportion of authors affiliated with each income bracket using Χ2 analysis. We conducted logistic regression to identify factors associated with first or last authorship affiliated with the study country.
    RESULTS: There were 14 113 authors in 1751 articles. Nearly half (45.5%) of the articles reported work conducted in lower middle-income countries (MICs), 23.6% in upper MICs, 22.5% in low-income countries (LICs). Authors affiliated with HICs were most represented (40.7%); 26.4% were affiliated with lower MICs, 17.4% with upper MICs, 10.3% with LICs and 5.1% with mixed affiliations. Among single-country studies, those without any local authors (8.7%) were most common among those conducted in LICs (14.4%). Only 31.0% of first authors and 21.3% of last authors were affiliated with LIC study countries. Studies in upper MICs (adjusted OR (aOR) 3.6, 95% CI 2.46 to 5.26) and those funded by the study country (aOR 2.94, 95% CI 2.05 to 4.20) had greater odds of having a local first author.
    CONCLUSIONS: There were significant disparities in authorship representation. Authors affiliated with HICs more commonly occupied the most prominent authorship positions. Recognising and addressing power imbalances in international, collaborative emergency medicine (EM) research is warranted. Innovative methods are needed to increase funding opportunities and other support for EM researchers in LMICs, particularly in LICs.

    21st century gender trends of authorship in the British Journal of Oral and Maxillofacial Surgery.
    Samuel Reeves, Wee Lee Loke, Maria Mullerat-Pigem, Dhruvi Patel, Peter A Brennan.
      Despite forming the majority in undergraduate medicine and dentistry programmes, females remain under-represented in all surgical specialties, including oral and maxillofacial surgery (OMFS). Efforts are ongoing to promote female uptake in surgery. Research output is a key metric in measuring leadership and academic advancement within a specialty. The aim of this study was to assess female authorship in research published in the British Journal of Oral and Maxillofacial Surgery from 2000-2020 with a retrospective cohort study of original articles and reviews published in the journal from five different volumes of the journal (2000, 2005, 2010, 2015, 2020 as representative time points). The gender of the first and last authors were assessed for gender by first name recognition and verified with a web-search of the author using their stated institutional affiliation when this was not clear. Articles were excluded if the gender of one of the first or last author could not be determined. A total of 501 articles were included with the gender of 1002 authors analysed. 173 (17.3%) authors were female, and 828 (82.7%) were male. The most common author combination was male-male (70.3%) and the least common female-female (4.8%). The proportion of female authors increased over time from 9.3% in 2000 to 23.4% in 2020. Females remain under-represented within surgery, but female presence in academic output is increasing at a similar rate to the numbers of female uptake in the clinical workforce which is a promising sign and indicative of progress towards gender parity.

    Visualization and analysis of mapping knowledge domains for coronavirus research.
    Weizhi Yao, Ling Tan, Liang Liu.
      BACKGROUND: In recent years, many countries around the world have been threatened by COVs. The aim of this study was to better grasp developments and trends in research on coronavirus around the world and to promote theoretical research into their prevention and control.METHODS: Research on coronavirus was reviewed and analyzed using bibliometrics based on a total of 4860 publications collected from the Web of Science Core Collection database. Yearly quantitative distribution of literature, country/region distribution, organization distribution, main source journal distribution, subject category distribution, research knowledge bases, and research hotspots and frontiers were all analyzed, and CiteSpace and VOSviewer were used to plot knowledge domain maps, Excel was used to plot keyword strategy diagram.
    RESULTS: Coronavirus research could be roughly divided into 4 stages: preliminary development stage (before 2000), rapid growth stage (2000-2005), slow decline stage (2006-2011) and sustained growth stage (since 2012). America had taken the leading position in this field. The study of COVs involves many subject categories, mainly includes virology, veterinary sciences, biology, and immunology. At present, the key words in the field of coronavirus research were mainly divided into 6 major hot clusters, namely, the introduction and structure analysis of coronavirus, the research on the outbreak source and transmission of coronavirus, the research on the infection pathway of coronavirus in human body, the research on the pathogenesis of coronavirus, the research on the diagnosis and symptoms of coronavirus infection, and the research on the treatment of coronavirus.
    CONCLUSION: Coronavirus, which occurs all over the world, often causes huge casualties and economic losses, and poses a serious threat to the safe and stable operation of the social and economic system. Objective literature review and analysis can help scholars in related fields to deepen their overall understanding. And, there are several key issues that should be further explored in future research.

    Essential signals in publication trends and collaboration patterns in global Research Integrity and Research Ethics (RIRE).
    A M Soehartono, L G Yu, K A Khor.
      Amid an increasingly demanding research environment, there has been a growing interest in studies concerning Research Integrity and Research Ethics (RIRE). Between 1990 and 2020, over 9700 publications were published to address problematic research conduct such as falsification, plagiarism, and related protocols and standards. In this work, country-level trends and collaborative structures are examined with respect to economic group. Our results showed that RIRE publications are predominantly led by the West, with North America and Western Europe contributing the most. While there is interest within growing economies such as China, the pace is not comparable to its overall publications. However, international collaborations on RIRE grew to account for nearly 30% of all publications on the subject in 2020. Although there is a stronger preference for high income countries to collaborate with other high income countries, we observe a rise in partnerships between high-/middle-income and middle-/lower-income co-authorship pairs in the last decade. These trends point to a maturing global community with distributed knowledge transfer, towards more unified international standards for research ethics and integrity.Supplementary Information: The online version contains supplementary material available at 10.1007/s11192-022-04400-y.

    Bibliometric Analysis of Network Pharmacology in Traditional Chinese Medicine.
    Runpei Miao, Qinggang Meng, Chennan Wang, Wenjing Yuan.
      Aim: We evaluated the developmental process, research status, and existing challenges of network pharmacology. Moreover, we elucidated the corresponding solutions to improve and develop network pharmacology.Methods: Research data for the current study were retrieved from the Web of Science. The developmental process of network pharmacology was analyzed using HisCite, whereas cooccurrence analysis of countries, institutions, keywords, and references in literature was conducted using CiteSpace.
    Results: In literature, there was a trend of annual increase of studies on network pharmacology and China was found to be the country with the most published literature on network pharmacology. The main publishing research institutions were universities of traditional Chinese medicine (TCM). The keywords with more research frequency were TCM, mechanisms, molecular docking, and quercetin, among others.
    Conclusion: Currently, studies on network pharmacology are mainly associated with the exploration of action mechanisms of TCM. The main active ingredient in many Chinese medicines is quercetin. This ingredient may lead to deviation of research results, inability to truly analyze active ingredients, and even mislead the research direction of TCM. Such deviation may be because the database fails to reflect the content and composition changes of Chinese medicinal components. The database does not account for interactions among components, targets, and diseases, and it ignores the different pathological states of the disease. Therefore, network pharmacology should be improved from the databases and research methods.

    Gamification for behavior change: A scientometric review.
    Simone Bassanelli, Nicola Vasta, Antonio Bucchiarone, Annapaola Marconi.
      Gamification, which refers to the use of game design elements in non-game contexts, provides similar experiences and motivations as games do; this makes gamification a useful approach to promote positive behaviors. As a useful tool for keeping users motivated, engaged and active, there is a wide interest in adopting gamification solutions for supporting and promoting positive behaviors and behavior change (e.g. quit smoking, ecological behaviors, food choices, civic engagement, mental healthcare, sustainability, etc.). In this study, we use the CiteSpace software to examine 984 publications and their 46,609 unique references on gamification applied for behavior change. The corpus of studies was downloaded from the Scopus database and refers to studies published between 2011 and the beginning of 2022. Several methods were used to analyze these data: (1) document co-citation analysis (DCA) was performed to identify the pivotal researches and the research areas; (2) author cocitation analysis (ACA) was performed to identify the main authors; (3) and keyword analysis was performed to detect the most influential keywords and their change over time. The results of the analysis provide an overview of the influential documents, authors and keywords that have given shape to the literature of the field, and how it has evolved, showing an initial interest in motivational and persuasion techniques, and in the gamification design, and subsequently in the development of more rigorous methodologies for both design and use. As the first scientometric review of gamification applied to behavior change, this study will be of interest to junior and senior researchers, graduate students, and professors seeking to identify research trends, topics, major publications, and influential scholars.

    Sustainable supply chain management and green technologies: a bibliometric review of literature.
    Zhang Yu, Muhammad Waqas, Muhammad Tabish, Muhammad Tanveer, Ikram Ul Haq, Syed Abdul Rehman Khan.
      To attain ecological sustainability and transition to sustainable supply chain management (SSCM), effective technological innovation (TI) and solid waste management (SWM), as likely impending resources, are essential components. From 2000 through 2021, a detailed map of SSCMs in the context of TI and systematic history will be created, highlighting the most significant research themes and trends, primary features, development, and possibly relevant areas for future study. Due to utilizing bibliometric analysis, text mining, and content analytics methodologies, the following concerns were addressed: (1) How has SSCM research progressed over time in the TI domain? (2) Which SSCM research areas and trends receive the most attention in the TI domain? Additionally, (3) what are the research directions for SSCM in the context of TI? As a result, bibliometric networks were developed and examined using 983 journal articles from the Scopus database to highlight the substantial body of literature. As a result, SSCM has been divided into five crucial study themes: (i) transition to TI, (ii) SSCM in closed-loop supply chains, (iii) municipal solid waste management (MSWM), (iv) environmental consequences and life-cycle evaluation, and (v) policymakers and practitioners in SSCM can use the SSCM research landscape and its primary highlight patterns to guide and add in the TI. Considering SSCM research as a way to reduce waste, future study directions are also suggested.

    What are the challenges for ohmic heating in the food industry? Insights of a bibliometric analysis.
    Ramon Silva, Ramon S Rocha, Gustavo Luis P A Ramos, Douglas Xavier-Santos, Tatiana C Pimentel, Jose M Lorenzo, Pedro Henrique Campelo, Marcia Cristina Silva, Erick A Esmerino, Mônica Q Freitas, Adriano G Cruz.
      The trends related to ohmic heating technology in food processing were evaluated using bibliometric analysis based on the scientific literature published in the last decade. Publications from Turkey, Brazil, and Iran represent 32% of all publications. Most studies have targeted the definition of the best combinations of operational parameters for application in different food matrices and their possible effects on the food properties. In addition, a tendency to use ohmic heating as an alternative technology for pasteurization was observed. Future studies should develop mathematical models that evaluate process parameters and food characteristics in the inactivation of microorganisms and enzymes and maintenance of bioactive compounds, the study of the non-thermal effect of electromagnetic waves on the food quality, the evaluation of the processing conditions and food physicochemical properties in the electrode corrosion and migration of metal ions to the treated food, and improvements of homogeneity during processing. This study was the first to perform a bibliometric analysis based on scientific literature concerning ohmic heating in food processing and presented the challenges, future trends, and evolution of scientific research.

    Tracing knowledge evolution flows in scholarly restaurant research: a main path analysis.
    Abderahman Rejeb, Alireza Abdollahi, Karim Rejeb, Mohamed M Mostafa.
      Restaurant research has received significant attention globally. This article aims to examine the evolution and the knowledge structure of restaurant research over the past decades. We also investigate the restaurant research hotspots and knowledge diffusion paths based on 1489 articles extracted from the Web of Science database. Furthermore, we conduct a keyword co-occurrence network analysis and four different types of main path analyses to scrutinize the historical formation of the restaurant research. Results revealed that restaurant research mainly focused on five research themes: consumer behavior, consumer satisfaction, social media, green restaurants, and authenticity. While consumer behavior has been the mainstream topic, the focus of this line of research has recently shifted from traditional to luxury and ethnic restaurants. Furthermore, our analysis has detected several recent changes in response to the COVID-19 pandemic. By examining the knowledge structure of restaurant research, we reveal its knowledge diffusion paths and provide avenues for future research in this vast and interdisciplinary research field.

    Time-based changes in authorship trend in research-intensive universities in Malaysia.
    Noor Lide Abu Kassim, Siti Khairunnisa Mohd Bakri, Fariha Nusrat, Elnaz Salim, Muhammad Manjurul Karim, Mohammad Tariqur Rahman.
      Considering the fact that publications serve as an important criterion to evaluate the scientific accomplishments of an individual within respective fields in academia, there has been an increasing trend to publish scientific articles whereby multiple authors are defined as primary, co-, or corresponding authors according to the roles performed. This article analyzes the authorship pattern in 4,561 papers (including 60 single-authored papers) from 1990 till 2020 of 94 academics who hold a position as professors and are affiliated with the Faculty of Medicine at three different research universities in Malaysia. Only 708 papers (15.5% of 4561 papers) were authored by less than 3 authors. In 3,080 papers (67.5% of 4561 papers), those academics appeared as co-authors. Using different years as cut-off periods, it was observed that the appearance as co-author in the papers had steeply risen around the years: 2006, 2007, 2008 and onwards. The increased number of authors in the multi-author papers and the appearance of the selected academics as co-authors reflect the extent of boosting of collaborative research in that period which corresponds to the adoption of the "publish or perish policy" by the Ministry of Higher Education in Malaysia.

    Gender Distribution Associated With the Journal Wilderness & Environmental Medicine.
    Linda E Keyes, Sarah M Schlein, Alainna B Brown, Natalya E Polukoff, Alicia Byrne, Neal W Pollock.
      INTRODUCTION: Publication and peer review are fundamental to career advancement in science and academic medicine. Studies demonstrate that women are underrepresented in science publishing. We evaluated the gender distribution of contributors to Wilderness & Environmental Medicine (WEM) from 2010 through 2019.METHODS: We extracted author data from ScienceDirect, reviewer data from the WEM Editorial Manager database, and editorial board data from journal records. Gender (female and male) was classified using automated probability-based assessment with Genderize.io software.
    RESULTS: A total of 2297 unique authors were published over the 10-y span, generating 3613 authorships, of which gender was classified for 96% (n=3480). Women represented 26% (n=572) of all authors, which breaks down to 22% of all, 19% of first, 28% of second, and 18% of last authorships. Women represented 20% of peer reviewers (508/2517), 20% of reviewers-in-training (19/72), and 16% of editorial board members (7/45). The proportion of female authors, first authors, and reviewers increased over time. Women received fewer invitations per reviewer than men (mean 2.1 [95% CI 2.0-2.3] vs 2.4 [95% CI 2.3-2.5]; P=0.004), accepted reviews at similar rates (mean 73 vs 71%; P=0.214), and returned reviews 1.4 d later (mean 10.4 [CI 9.5-11.3] vs 9.0 d [95% CI 8.5-9.6]; P=0.005).
    CONCLUSIONS: While female representation increased over the study period, women comprise a minority of WEM authors, peer reviewers, and editorial board members. Gender equity could be improved by identifying and eliminating barriers to participation, addressing any potential bias in review processes, implementing strategies to increase female-authored submissions, and increasing mentorship and training.

    Perfluoroalkyl substance pollution: detecting and visualizing emerging trends based on CiteSpace.
    Jiahao Huang, Song Xiang, Shuqin Chen, Wei Wu, Tianyin Huang, Yan Pang.
      In recent years, perfluoroalkyl substances (PFASs) have been detected in all kinds of environmental media and can harm animals and human beings. They have attracted the attention of environmental workers worldwide and have become another research hotspot in the field of environment. However, analyses of PFASs have seldom been studied systematically. Therefore, this study summarizes the available data in 6756 publications (2000-2022) using the CiteSpace software to provide insights into the specific characteristics of PFASs and consequently shows global development trends that scientists can use for establishing future research directions. As opposed to traditional review articles by experts, this study provides a new method for quantitatively visualizing information about the development of this field over the past 23 years. Results show that the countries with more research in this field are mainly the USA and China. The research on PFASs is mainly concentrated in environmental sciences and ecology. Zhanyun Wang and Robert C. Buck's research has the highest influence rate in this field, and their research group is worthy of attention. Through the analysis of hot keywords, we conclude that the research hotspots are mainly focused on PFASs' transmission media and pathways, human exposure and the mechanism of toxicity, and degradation and remediation measures. Collectively these results indicate the major themes of PFAS research are as follows: (1) transmission media and pathways, (2) human exposure and the mechanism of toxicity, (3) degradation and remediation measures. This study maps the major research domains of PFAS research; explanations and implications of the findings are discussed; and emerging trends highlighted.

    Frequency and Content of the Last Fifty Years of Papers on Aristotle's Writings on Biological Phenomena.
    Christopher F Sharpley, Clemens Koehn.
      Aristotle is often named as the first zoologist or biologist because of his writings on animals. Although Aristotle's major intention in these books was to illustrate his ideas of how knowledge and understanding might advance, at least one modern biologist (C. Darwin) has recognized Aristotle's depth and breadth as being of surviving merit. Of greater surprise is the ongoing attention that his works continue to receive, including publications in contemporary scientific journals. This review identifies 38 peer-reviewed papers on various topics from Aristotle's biological writings that have been published during the last 50 years. These papers are described according to content (genetics, population biology, anatomy, brain, movement), specific creatures (fish, scorpions, elephants, insects, birds), publication outlet, distribution over the fifty year period surveyed, and visible trends in the topics studied. It is concluded that, in the highly-competitive field of peer-reviewed scientific publication and citation, Aristotle's biology continues to excite the interest of scientists and remains salient to modern science itself.

    A stochastic generative model for citation networks among academic papers.
    Yuichiro Yasui, Junji Nakano.
      We propose a stochastic generative model to represent a directed graph constructed by citations among academic papers, where nodes and directed edges represent papers with discrete publication time and citations respectively. The proposed model assumes that a citation between two papers occurs with a probability based on the type of the citing paper, the importance of cited paper, and the difference between their publication times, like the existing models. We consider the out-degrees of citing paper as its type, because, for example, survey paper cites many papers. We approximate the importance of a cited paper by its in-degrees. In our model, we adopt three functions: a logistic function for illustrating the numbers of papers published in discrete time, an inverse Gaussian probability distribution function to express the aging effect based on the difference between publication times, and an exponential distribution (or a generalized Pareto distribution) for describing the out-degree distribution. We consider that our model is a more reasonable and appropriate stochastic model than other existing models and can perform complete simulations without using original data. In this paper, we first use the Web of Science database and see the features used in our model. By using the proposed model, we can generate simulated graphs and demonstrate that they are similar to the original data concerning the in- and out-degree distributions, and node triangle participation. In addition, we analyze two other citation networks derived from physics papers in the arXiv database and verify the effectiveness of the model.

    Women in neurosurgery: review of the literature combined with a gender-based analysis of the development over the past 20 years in Austria.
    Veronika Sperl, Barbara Kiesel, Marlies Bauer, Lisa I Wadiura.
      BACKGROUND: The number of female neurosurgeons has grown over the last decades, however, a gender gap still exists in most western countries. The reasons for this gender gap remain mostly unclear. The aim of the present study was to analyze the development of the numbers of female neurosurgeons in Austria over the last 20 years in comparison to other surgical disciplines. Additionally, a literature review was performed summarizing articles reporting on women in neurosurgery.METHODS: Data including male and female residents as well as board certified surgeons over the last 20 years retrieved from the Austrian Medical Association were collected. An additional PubMed query was performed focusing on literature reporting on working conditions, work-life-balance as well as data of female leading positions.
    RESULTS: In 2021, 5237 surgeons were registered at the Austrian Medical Association including 258 (5%) neurosurgeons. In total, 1081 of 5237 (21%) surgeons and 61 of 253 (24%) of all Austrian neurosurgeons were female. In comparison to the percentage of women in all surgical disciplines, the number of female neurosurgeons is represented slightly above the average of 21%. According to data representing the trend of the last 20 years, the percentage of female neurosurgeons in Austria has doubled over the last 20 years. Comparably, this trend can be observed in all surgical disciplines.
    CONCLUSIONS: The percentage of female neurosurgeons in Austria are constantly increasing over the last 20 years, however a gender gap still exists. Consequently, studies are warranted to analyse the causes to improve the reported gender gap in Neurosurgery.

    Carbon-based adsorbents as proficient tools for the removal of heavy metals from aqueous solution: A state of art-review emphasizing recent progress and prospects.
    Narayanan Mahesh, Srinivasan Balakumar, Shanmugasundaram Shyamalagowri, Jagadeesan Manjunathan, M K S Pavithra, Palanisamy Suresh Babu, Murugesan Kamaraj, Muthusamy Govarthanan.
      Carbon-centric adsorbents (CCA) are diverse forms, from simple biochar (BC) to graphene derivatives, carbon nanotubes (CNTs), and activated carbon (AC), which have been vastly explored for their removal of a plethora of pollutants, including heavy metals (HM). The prominent features of CCA are their operational attributes like extensive surface area, the occurrence of flexible surface functional groups, etc. This work offers a comprehensive examination of contemporary research on CCA for their superior metal removal aptitude and performances in simulated solutions and wastewater flows; via portraying the recent research advances as an outlook on the appliances of CACs for heavy metal adsorption for removal via distinct forms like AC, BC, Graphene oxide (GO), and CNTs. The bibliometric analysis tool was employed to highlight the number of documents, country-wise contribution, and co-occurrence mapping based on the Scopus database. The coverage of research works in this review is limited to the last 5 years (2017-2021) to highlight recent progress and prospects in using CCAs such as AC, BC, GO, and CNTs to remove HM from aqueous media, which makes the review unique. Besides an overview of the common mechanisms of CACs, the future scope of CAC, especially towards HM mitigation, is also discussed in this review. This review endorses that further efforts should be commenced to enhance the repertory of CCAs that effectively eliminate multiple targeted metals in both simulated and real wastewater.

      It has been widely reported that women are underrepresented in leadership positions within academic medicine. This study aimed to assess trends in women representation as principal investigators (PIs) in oncology clinical trials and to characterize trends in women's leadership in such trials conducted between 1999 and 2019. The gender of 39,240 PIs leading clinical trials was determined using the gender prediction software Genderize.io. In total, 11,516 (27.7%) women served as PIs. Over the past 20 years, an annual increase of 0.65% in women PIs was observed. Analysis by geographic distribution revealed higher women representation among PIs in North America and Europe compared to Asia. Industry-funded trials were associated with lower women PI representation than academic-funded trials (31.4% vs. 18.8%, p<0.001). Also, women PIs were found to be underrepresented in late-phase as compared to early-phase studies (27.9%, 25.7%, 21.6%, and 22.4% in phase I, II, III, and IV, respectively; Cochran-Armitage test for trend, p<0.001). Furthermore, an association was found between the PI's gender and enrolment of female subjects (50% vs. 43% female participants led by women vs men PIs, respectively, p<0.001). Taken together, while the gender gap in women's leadership in oncology trials has been steadily closing, prominent inequalities remain in non-Western countries, advanced study phases, industry-funded trials and appear to be linked to a gender gap in patient accrual. These observations can serve for the development of strategies to increase women's representation and to monitor progress toward gender equality in PIs of cancer clinical trials.
