    Top 100 cited Articles in Charcot Neuroarthropathy.
    Megna Panchbhavi.
      BACKGROUND AND AIMS: An article's scientific impact has often been measured by the number of citations it receives, and a citation analysis can help determine impactful works in medical specialties. The objective of this study is to describe the metrics and levels of evidence of articles in Charcot neuroarthropathy.METHODS: This study reviewed the top 100 most cited articles available when searching for articles in electronic database using the keywords "Charcot neuroarthropathy." Each article was examined for the number of citations, publication type, journal specialty, authorship, country of origin, year of publication, level of evidence, and total sample size.
    RESULTS: The number of citations ranged from 20 to 490. The 100 most cited articles were published in 48 journals, spanning from general to more specific subspecialty journals. 19% of articles were published by the Journal of Foot and Ankle Surgery. The most common level of evidence was V (42 out of 100 articles), and most articles were literature reviews (n = 42) and case series (n = 27). The median sample size in experimental studies was 29. Out of 100 articles, only 5 were randomized controlled trials.
    CONCLUSIONS: The median year of most cited publications, 2008, suggests a need for newer studies reviewing Charcot neuroarthropathy. The paucity of articles with an evidence level of 1 or 2 along with small median sample size suggests a lack of scientifically rigorous studies reviewing Charcot neuropathy. Identification of most cited papers about Charcot neuroarthropathy gives clinicians insight into the general scientific review of the disorder.

    Seven decades of Ramadan intermittent fasting research: Bibliometrics analysis, global trends, and future directions.
    Khaled Obaideen, Katia H Abu Shihab, Mohamed I Madkour, MoezAlIslam E Faris.
      BACKGROUND AND AIMS: There is a large body of research focused on various aspects related to Ramadan intermittent fasting (RIF) and human health and disease. This study aimed to quantify the bibliometric data of RIF medical research over the past seven decades and explore these variables qualitatively via text mining analysis.METHODS: We used the Scopus search engine to identify published articles related to RIF from inception to December 31, 2021. All types of research articles were included. Scientometric and bibliometric measures were determined using Excel, Biblioshiny, and VOSviewer. This study proposed a bibliometric and text mining method to qualitatively and quantitatively recognize the RIF research trend.
    RESULTS: The Scopus search returned 1915 relevant articles. Most citations pertained to publications from the last two decades, and most publications were original research articles. These publications had received around 27,000 citations, and the 20 most prolific publishing journals had an average h-index of 112.25. More than one-third of all medical publications were in open-access journals. There was a 13-fold increase in medical research on RIF over the past few decades. We identified the 10 most prolific publishing countries, institutes, journals, and authors. We also identified five scientific hotspots of RIF scientific literature, which were: diabetes, metabolic health, public health, physiology, and maternity.
    CONCLUSION: This is the first comprehensive bibliometric analysis of medical research related to RIF. The research gaps identified will shape future research directions and foster collaborative research activities toward enhanced medical nutrition research revolving around RIF.

    Xiaoli Yang, Hua Yin, Deyu Zhang, Lisi Peng, Keliang Li, Fang Cui, Chuanchao Xia, Zhaoshen Li, Haojie Huang.
      Cathepsin B (CTSB) is a lysosomal protease implicated in the progression of various diseases. A large number of CTSB-related studies have been conducted to date. However, there is no comprehensive bibliometric analysis on this subject. In our study, we performed quantitative analysis of CTSB-related publications retrieved from the Science Citation Index Expanded (SCIE) of the Web of Science Core Collection (reference period: 2011-2021). A total of 3,062 original articles and reviews were retrieved. The largest number of publications were from USA (n = 847, 27.66%). The research output of each country showed positive correlation with gross domestic product (GDP) (r = 0.9745, P < 0.0001). Active collaborations between countries/regions were also observed. Reinheckel T and Sloane BF were perhaps the most impactful researchers in the research landscape of CTSB. Plos ONE was the most prevalent (119/3,062, 3.89%) and cited journal (3,021 citations). Comprehensive analysis of the top citations, co-citations, and keywords was performed to acquire the theoretical basis and hotspots of CTSB-related research. The main topics included CTSB-related cancers and inflammatory diseases, CTSB-associated cell death pattern, and the applications of CTSB. These results provide comprehensive insights into the current status of global CTSB-related research especially in pancreas, which is worthy of continued follow-up by practitioners and clinicians in this field.

    Bibliometric Analysis of 100 Most-Cited Articles in Delirium.
    Xinxing Fei, Qiu Zeng, Jianxiong Wang, Yaqian Gao, Fangyuan Xu.
      Delirium is a cognitive disorder with complex etiology, which brings a great burden to social health care. Articles with high citation frequency can provide important information about the current research situation in a certain field. Web of Science was used to search the 100 most-cited articles and we extracted key information, such as the authors, countries/regions, institutions, journals, and study types of these articles. CiteSpace was used to visually analyze the keywords. Our bibliometric analysis shows that the attention in this field continues to rise. Authors from the United States published the most articles and Inouye SK is the most influential author in the field. The journals that published these articles have high impact factors. Cohort studies are the main cited articles in this field, and there are a large number of systematic reviews or meta-analyses of cohort studies. Risk factors for delirium, psychometric evaluation, hospital care, and various clinical study design are still the focus of research. In short, we summarized the 100 most-cited articles in the field of delirium to identify the current status and global trends. These results enable researchers to understand the quality and trend of research in the field of delirium and make better use of the classical literature.

    Global Trends and Research Hotspots of Exercise for Intervening Diabetes: A Bibliometric Analysis.
    Zhijie Zhang, Yuanchun Zhu, Qingfeng Wang, Tiantian Chang, Chunlong Liu, Yi Zhu, Xueqiang Wang, Xiangyang Cao.
      Background: Diabetes is a chronic metabolic disease characterized by hyperglycemia that often occurs in adults. Many studies have indicated that exercise is beneficial to the medical management of diabetes. Bibliometric analysis can help investigators to identify the current research concerns to guide future research directions. Nevertheless, the overview bibliometric analysis of this global research topic related to exercise and diabetes is lacking. The present bibliometric study aimed to investigate development trends and research hotspots of exercise and diabetes research and provide researchers with new perspectives in further studies.Materials and Methods: The articles and reviews regarding exercise and diabetes between 2000 and 2020 were retrieved from the Web of Science Core Collection. The scientometrics analytical tool CiteSpace software was used to analyze the cooperation among countries/institutions/journals/authors, analysis of co-occurrence keywords, keywords bursts, and references.
    Results: In all, 3,029 peer-reviewed papers were found with a persistently increased tendency over time. The most prolific country and institution were the USA (965) and Univ Alberta (76), respectively. Diabetes Care published most papers (178) and was the most co-cited journal (2,630). Riddell MC had the most publications (53), and Sigal RJ was the most influential author (503 cited times). Colberg et al.'s paper (co-citation counts: 183) showed the strongest citation bursts by the end of 2020, which was the most representative reference. The four research focuses were mellitus, exercise, physical activity, and glycemic control. The two frontiers trends were sedentary behavior and stress. The combination of aerobic and resistance training can effectively improve glycemic control, decrease HbA1c levels, enhance cardiorespiratory fitness, improve lipid levels, and decrease the demand for non-insulin antihyperglycemic agents.
    Conclusions: This study offers a scientific perspective on exercise and diabetes research and provides investigators with valuable information to detect the current research condition, hotspots, and emerging trends for further study.

    Upper cervical spine instability systematic review: a bibliometric analysis of the 100 most influential publications.
    Christopher Michel, Christopher Dijanic, George Abdelmalek, Suleiman Sudah, Daniel Kerrigan, Praveen Yalamanchili.
      Background: Instability in the upper cervical spine, although rare, can be devastating. This spectrum of conditions includes occipitocervical instability, atlantoaxial instability and atlantoaxial rotatory displacement. Knowledge of the literature can provide better understanding of disease processes and management, and aid in clinical decision making. The objective of this study was to perform a bibliometric analysis to formulate a comprehensive review of the most cited publications.Methods: A systematic search of the literature was conducted using the Clarivate Web of Science database. The search query was '"Atlanto-occipital dislocation" OR "atlanto-occipital dissociation" OR "atlantoaxial rotatory displacement" OR "atlantoaxial instability"'. The top 100 articles based on frequency of citation were included in our study. Data extracted from articles included frequency of citation, year of publication, country of origin, journal of publication, level of evidence and article type.
    Results: Our initial search yielded 257 results that met the criteria. Articles not pertaining to atlanto-occipital instability were removed. Citation frequency ranged from 15 to 195. The most cited article was "Traumatic Anterior Atlanto-Occipital Dislocation" published by Powers et al. in 1979. The most productive decade was 2000-2009 with 45 publications. All decades showed a progressive increase in the number of papers published except for 2010-2019. Overall, 19 countries contributed and the most productive was the United States (n=61). The articles found in our search were cited a total of 4,095 times (3,463 without self-citations) averaging 40.95 citations per publication.
    Discussion: The goal of a bibliometric study is to assess trends in a specific field of study, provide evidence for the impact of an individual or field of study's research, and highlight potential areas for future research. While the number of citations does not necessarily reflect publication quality, it reflects overall influence based on recognition by peers in the field. Publications from the last 20 years have emphasized the use of newer technologies such as computed tomography (CT) and magnetic resonance imaging (MRI) to aid in diagnosis. Our study highlights the lack of high-level evidence articles and underscores that our understanding of these conditions in both pediatric and adult patients is maturing.

    Dylan Luxenburg, David Constantinescu, Gemma St Louis, Kevin J Bondar, Suleiman Y Sudah, Michele D'Apuzzo.
      Background: This study aims to identify the most frequently cited articles published in the Journal of Arthroplasty (JOA) and to analyze the trends in the content and contributors of the literature within the journal.Methods: The 100 most cited articles published in the JOA were accessed using the Scopus database. The number of citations, year of publication, level of evidence (LOE), article type, country of origin, and contributing institution were each recorded for each article.
    Results: The United States (63%) was the most prolific publishing nation. The 1990s (30%) and 2000s (47%) were the most productive decades. The most common article category was clinical outcomes (33%), followed by technical note (16%) and biomechanics (14%). The plurality of the top 100 articles were well-designed case-control or cohort studies of LOE II (46%) followed by LOE V (32%) and LOE I (11%).
    Conclusions: Using citation analysis, the most influential articles in the JOA were comprehensively and objectively analyzed. The most popular fields of research involved clinical outcomes (33%) and technical note (16%), both of which increase an article's likelihood of being highly cited. Knowledge of the most influential articles in the JOA allows for appreciation of current and potential future areas of literature regarding diagnosis, management, and outcome of a patient undergoing arthroplasty.

    Xing-Peng Di, Liao Peng, Li-Yuan Xiang, Meng-Hua Wang, Jie Zhang, De-Yi Luo.
      INTRODUCTION AND HYPOTHESIS: To identify and compare the top-cited articles from all indexed journals and urology-nephrology and obstetrics-gynecology journals in the Institute for Scientific Information Web of Science's Citation Index Expanded on interstitial cystitis and bladder pain syndrome (IC/BPS).METHODS: Cross-sectional bibliometric analysis of top-cited articles in Web of ScienceTM (WoS) from 1900-2022. The articles were retrieved by the MeSH terms from NCBI. The characteristics of top 100 cited articles from all indexed journals and specialized journals were evaluated.
    RESULTS: A total of 5547 articles were collected from 1115 journals, in which 3225 articles were from 141 urological and gynecological specialized journals. The USA and the UK were the top two origins for articles on interstitial cystitis. The articles from non-specialized journals were more frequently cited than those from specialized journals (median [IQR], 221.5 [189.8-313.5] vs 131.0 [126.0-142.8], P < 0.0001). The citation number per year showed similar results (median [IQR], 239.9 [194.5-311.8] vs 132.0 [126.7-140.5], P < 0.0001). There were many more open-access articles in non-specialized than specialized journals (P = 0.0018).
    CONCLUSIONS: The current study initially queried the articles published on WoS on IC/BPS by the number of citations to identify the differences between two journal categories. The characteristics and trends of research were analyzed by citations to provide insights into the current research status and future direction.

    Tauseef Ahmad, Mukhtiar Baig, Sahar Shafik Othman, Husam Malibary, Shabir Ahmad, Syed Majid Rasheed, Mohammad T Al Bataineh, Basem Al-Omari.
      PURPOSE: This study aims to analyze and characterize anthrax vaccine-related research, key developments, global research trends, and mapping of published scientific research articles during the last three decades (1991-2021).METHODS: A bibliometric and visualized study was conducted. The Web of Science Core Collection database (WoSCC) was searched using relevant keywords ("Anthrax" OR "Anthrax bacterium" OR "Bacillus anthracis" OR "Bacteridium anthracis" OR "Bacillus cereus var. Anthracis" (Topic)) AND ("Vaccine" OR "Vaccines" OR "Immunization" OR "Immunisation" OR "Immunizations" OR "Immunisations" (Topic)) with specific restrictions. The data was analyzed and plotted by using different bibliometric software and tools (HistCiteTM software, version 12.3.17, Bibliometrix: An R-tool version 3.2.1, and VOSviewer software, version 1.6.17).
    RESULTS: The initial search yielded 1750 documents. After screening the titles and abstracts of the published studies, a total of 1090 articles published from 1991 to 2021 were included in the final analysis. These articles were published in 334 journals and were authored by 4567 authors from 64 countries with a collaboration index of 4.32. The annual scientific production growth rate was found to be 9.68%. The analyzed articles were cited 31335 times. The most productive year was 2006 (n = 77, 7.06%), while the most cited year was 2007 (2561 citations). The leading authors and journals in anthrax research were Rakesh Bhatnagar from Jawaharlal Nehru University, India (n = 35, 3.21%), and Vaccine (n = 1830, 16.51%), while the most cited author and journal were Arthur M. Friedlander from the United States Department of Defense (n = 2762), and Vaccine (n = 5696), respectively. The most studied recent research trend topics were lethal, double-blind, epidemiology, B surface antigen, disease, and toxin. The United States of America (USA) was the most dominant country in terms of publications, citations, corresponding author country, and global collaboration in anthrax vaccine research. The USA had the strongest collaboration with the United Kingdom (UK), China, Canada, Germany, and France.
    CONCLUSION: This is the first bibliometric study that provides a comprehensive historical overview of scientific studies. From 2006 to 2008, more than 20% of the total articles were published; however, a decrease was observed since 2013 in anthrax vaccine research. The developed countries made significant contributions to anthrax vaccine-related research, especially the USA. Among the top 10 leading authors, six authors are from the USA. The majority of the top leading institutions are also from the USA. About 90% of the total studies were funded by the United States Department of Health and Human Services (HHS), National Institutes of Health (NIH), USA, and the National Institute of Allergy and Infectious Diseases (NIAID), USA.

    Mapping the Hot Spots and Evolution Main Path of Whole-Body Vibration Training Since the 21st Century: A Bibliometric Analysis.
    Dan Dong, Mingli Sun, Dan Xu, Shuang Han, Liyuan Cui, Shu Cao, Ying Yang, Shuang Xu.
      To evaluate the global scientific output of the research on whole-body vibration training (WBVT) and explore the current status and trends in this field over the past decades using bibliometric methods, we retrieved the literature related to WBVT from 2000 to the present in the Web of Science Core Collection (WoSCC). We analyzed annual publications, citations, countries, organizations, productive authors, and source 14 journals by the Web of Science online bibliometric analysis. We visualized the WBVT research trends and explored influential organizations and authors through VOSviewer. Then, we constructed a citation chronology map by HistCite to obtain the knowledge base of this field and made a primary citation path analysis by Pajek. Finally, we mined the hot spots of WBVT by BICOMB and gCLUTO. Overall, there were 1,629 publications included in this study between 2000 and 2022. The United States contributed the most publications in this field, and the country with the most active partnership was Spain. The University of Cologne ranked highest among top productive organizations. Bernardo-Filho, Mario, from Universidade do Estado do Rio de Janeiro, ranked first among the top productive authors. The Journal of Strength and Conditioning Research topped the list of journals with the most publications on WBVT by a wide margin. The WBVT research field started from Rittweger's study on the acute physiological effects of WBVT in 2000, which was divided into two stages. The first stage focused on improving athletic ability, and the second stage gradually turned to the application in medicine. A keyword analysis showed the exercise rehabilitation of several aging chronic diseases was the research trend and hot spot of WBVT. The current study provided a time-based development and a global network hub for WBVT research, contributing to identifying core target diseases of WBVT and providing various insights for researchers in the future.

    Ya Wang, Dandan Li, Zijun Jia, Jiaqi Hui, Qiqi Xin, Qingbing Zhou, Weihong Cong, Fengqin Xu.
      Background: Emerging evidence has linked gut microbiota (GM) and its related metabolites to atherosclerosis (AS). This study aimed to analyze the evolution of GM in AS in the past decades, and provide valuable insights in this field.Methods: Web of Science Core Collection (WoSCC) was applied to retrieve the publications related to GM in AS from their inception until 2 December 2021, and the data was analyzed in Microsoft Excel, Scimago Graphica, CiteSpace, and VOSviewer.
    Results: In total, 560 documents were extracted from the WoSCC databases. The publications have shown rapid growth since 2008. China and Cleveland Clin were the most prolific country and institution, respectively. The journal with the most publications is Nutrients, and Nature was the most co-cited journal. Among 3556 related authors, Hazen, Stanley L., Tang, W. H. Wilson, and Wang, Zeneng were the top 3 contributing authors in this field. Aside from "gut microbiota," "atherosclerosis," the terms "TMAO," "metabolite," "obesity," and "phosphatidylcholine" were frequently occurred in the abstract and title of articles. Burst detection of keywords indicated that "metabolic syndrome," "acid," and "bile acid" were hot topics in recent years. According to the co-citation analysis of references, the research focus in this area has changed over time, and recent researches focus on choline, hypertension, butyrate, and berberine.
    Conclusion: Our study showed that the researches of GM in AS have been flourishing, and the content themes were constantly deepened. Human GM is critical to atherosclerotic diseases, and this hot topic is still worthy of more focus in the future.

    Predicting article citations using data from 100 top-cited publications in the field of Psoriasis Vulgaris and biological agents (PVBA) since 1991: A bibliometric analysis.
    Chieh-Hsun Chen, Tsair-Wei Chien, Sam Yu-Chieh Ho, Feng-Jie Lai.
      BACKGROUND: Psoriasis Vulgaris is a chronic inflammatory disease characterized by keratinocyte hyperproliferation. Bibliometric analysis helps determine the most influential article on the topic of "Psoriasis Vulgaris and biological agents (PVBAs)", and what factors affect article citation remain unclear. This study aims (1) to identify the top 100 most cited articles in PVBA (PVBA100 for short) from 1991 to 2020, (2) to visualize dominant entities on one diagram using data in PVBA100, and (3) to investigate whether medical subject headings (MeSH terms) can be used to predict article citations.METHODS: The top 100 most cited articles relevant to PVBA (1991-2020) were downloaded by searching the PubMed database. Citation analysis was applied to compare the dominant roles in article types and topic categories using pyramid plots. Social network analysis (SNA) and Sankey diagrams were applied to highlight prominent entities. We examined the MeSH prediction effect on article citations using its correlation coefficients.
    RESULTS: The most frequent article types and topic categories were research support by institutes (46%) and drug therapy (88%), respectively. The most productive countries were the United States (38%), followed by Germany (13%) and Japan (12%). Most articles were published in Br J Dermatol (13%) and J Invest Dermatol (11%). MeSH terms were evident in the prediction power of the number of article citations (correlation coefficient=0.45, t=4.99).
    CONCLUSIONS: The breakthrough was made by developing one dashboard to display PVBA100. MeSH terms can be used for predicting article citations in PVBA100. These visualizations of PVBA100 could be applied to future academic pursuits and applications in other academic disciplines.

      Background: Maternal stress during pregnancy can raise the risk of mental disorders in offspring. The continuous emergence of clinical concepts and the introduction of new technologies are great challenges. In this study, through bibliometric analysis, the research trends and hotspots on prenatal stress (PS) were explored to comprehend clinical treatments and recommend future scientific research directions.Methods: Studies on PS published on the Web of Science Core Collection (WoSCC) database between 2011 and 2021 were reviewed. Bibliometric analysis was conducted according to the number of publications, keywords, journals, citations, affiliations, and countries. With the data collected from the WoSCC, visualization of geographic distribution; clustering analysis of keywords, affiliations, and authors; and descriptive analysis and review of PS were carried out.
    Results: A total of 7,087 articles published in 2011-2021 were retrieved. During this period, the number of publications increased. Psychoneuroendocrinology is the leading journal on PS. The largest contributor was the United States. The University of California system was leading among institutions conducting relevant research. Wang H, King S, and Tain YL were scholars with significant contributions. Hotspots were classified into four clusters, namely, pregnancy, prenatal stress, oxidative stress, and growth.
    Conclusion: The number of studies on PS increased. Journals, countries, institutions, researchers with the most contributions, and most cited articles worldwide were extracted. Studies have mostly concentrated on treating diseases, the application of new technologies, and the analysis of epidemiological characteristics. Multidisciplinary integration is becoming the focus of current development. Epigenetics is increasingly used in studies on PS. Thus, it constitutes a solid foundation for future clinical medical and scientific research.

    Xavier Rossello, Albert Massó-van Roessel, Ovidiu Chioncel, Luigi Tavazzi, Roberto Ferrari, Alec Vahanian, Chris P Gale, Bogdan A Popescu, Aldo P Maggioni.
      AIMS: Given the lack of reliable observational data, network of volunteer centers, and standardised methodological procedures, the European Society of Cardiology EURObservational Research Programme (EORP) was set to provide a better understanding of real-world cardiovascular care and outcomes. We aimed to evaluate the scientific impact of EORP using a bibliometric approach.METHODS AND RESULTS: We collected data for each individual publication, and for each individual journal with at least one EORP publication. Bibliometric indicators evaluating research performance were categorised into those evaluating EORP publications (publication-based indicators), and those assessing the journals where those papers were published (journal-based indicators). During the first ∼11 years since its inception, we found that EORP produced 189 publications, with most published in journals in the first quartile (60.9%) or the second quartile (33.5%) of the Web of Science Journal Citation Report. The total number of citations to EORP publications was 9630 (average citation per publication of 51, h index of 54, 29 EORP publications with ≥ 100 citations). Of EORP publications, 20 had an Altmetric Attention Score higher than 50 and 9 had a score higher than 100. Fifty-two EORP papers have been cited 65 times in ESC Clinical Practice Guidelines between 2013 and 2021.
    CONCLUSION: EORP registries have contributed to impactful scientific knowledge. The high-quality metrics highlight the relevance of EORP international cardiovascular registries on the academic community. Efforts are needed to support this and other programmes aimed at delivering real-world evidence from independent patient data of cardiovascular care and outcomes across multiple geographies.

    Publication Trends of Research on Gallbladder Cancer During 2001-2021: A 20-Year Bibliometric Analysis.
    Wentao Sun, Wenze Wan, Zhihui Gao, Tao Suo, Sheng Shen, Houbao Liu.
      Gallbladder cancer (GBC) is one of the lethal cancers with an extremely poor prognosis. In the recent 20 years, research on GBC has developed rapidly. Here we aim to perform a systematical bibliometric analysis on the current foci and status of GBC research. This study analyzes trends in GBC research and compares contributions from different countries and regions, institutions, and authors. All publications in GBC research from 2001 to 2021 in the Web of Science Core Collection (WoSCC) database were collected. Microsoft Excel 2010 and GraphPad Prism 9 were used to analyze publication data and publication trends. VOSviewer 1.6.17 was adapted to generate a visual network of keywords in surgical training research. A total of 3,323 publications were included. China was the most productive country, with the highest number of publications (n = 900, 27.08%). Shanghai Jiaotong University and Roa JC were the most productive institution and authors, contributing 215 and 89 publications, respectively. Keywords were classified into five clusters, each representing a key topic. The main clusters of GBC are related to surgery therapy, mechanism research-related study, and non-surgery therapy, while migration is the current hotspot of GBC research. The scientific progression of GBC research over the past two decades was comprehensively analyzed by this bibliometric study. Finding deeper mechanisms in the migration of GBC cells, new biomarkers, and highly effective nomograms will be the major problems and directions in the future.

    Treatment of Liver Fibrosis: A 20-Year Bibliometric and Knowledge-Map Analysis.
    Yun-Kai Dai, Zhi-Min Zhao, Chenghai Liu.
      Objectives: To analyze the research hotspots, evolution, and trends of the treatment of liver fibrosis in the recent 20 years, bibliometric and knowledge-map analysis were used. Methods: Publications associated with the treatment of liver fibrosis were retrieved from the Web of Science Core Collection on 16 April 2022. CiteSpace 5.8.R3 and VOSviewer 1.6.18 were calculated to perform bibliometric and knowledge-map analysis. Results: A total of 72,686 authors from 200 institutions in 134 countries/regions published 15,237 studies in different academic journals. United States was the most productive country, and Shanghai Jiao Tong University was the most published institution. Trauner Michael had the most published articles, whereas Scott L. Friedman was the most frequently co-cited author. Moreover, there was frequent inter-institution cooperation between countries in the years 2015 and after, but the before years showed rare inter-institution cooperation. The journal HEPATOLOGY was both the most published publication and the most frequently co-cited one in this field. Screened keywords, such as virus infection, inflammation, oxidative stress, activation of hepatic stellate cell (HSC), and hepatocellular apoptosis, could be both therapeutic targets and pathological mechanisms in terms of liver fibrosis. Furthermore, long-term suppression of hepatitis B virus replication and the activation of HSC were the latest hotspots and topics related to the treatment of liver fibrosis. Besides, the treatments of nonalcoholic fatty liver disease and nonalcoholic steatohepatitis were also involved in the treatment of liver fibrosis, which were both emerging topics and rapidly developing hot fields. Conclusion: This bibliometric analysis conducted a full overview of the treatment of liver fibrosis, which provided important clues and ideas for scholars focusing on this field. Not only that, the field is still in a stage of rapid development and will continue to be a research hotspot in the future.

    A Bibliometric Analysis of Electrospun Nanofibers for Dentistry.
    Shixin Jin, Andy Wai Kan Yeung, Chengfei Zhang, James Kit-Hon Tsoi.
      Electrospun nanofibers have been widely used in dentistry due to their excellent properties, such as high surface area and high porosity, this bibliometric study aimed to review the application fields, research status, and development trends of electrospun nanofibers in different fields of dentistry in recent years. All of the data were obtained from the Web of Science from 2004 to 2021. Origin, Microsoft Excel, VOSviewer, and Carrot2 were used to process, analyze, and evaluate the publication year, countries/region, affiliations, authors, citations, keywords, and journal data. After being refined by the year of publication, document types and research fields, a total of 378 publications were included in this study, and an increasing number of publications was evident. Through linear regression calculations, it is predicted that the number of published articles in 2022 will be 66. The most published journal about electrospun dental materials is Materials Science & Engineering C-Materials for Biological Applications, among the six core journals identified, the percent of journals with Journal Citation Reports (JCR) Q1 was 60%. A total of 17.60% of the publications originated from China, and the most productive institution was the University of Sheffield. Among all the 1949 authors, the most productive author was Marco C. Bottino. Most electrospun dental nanofibers are used in periodontal regeneration, and Polycaprolactone (PCL) is the most frequently used material in all studies. With the global upsurge in research on electrospun dental materials, bone regeneration, tissue regeneration, and cell differentiation and proliferation will still be the research hotspots of electrospun dental materials in recent years. Extensive collaboration and citations among authors, institutions and countries will also reach a new level.

    A Bibliometric and Visualized Analysis of Uremic Cardiomyopathy From 1990 to 2021.
    Jing-Fu Bao, Pan-Pan Hu, Qin-Ying She, Difei Zhang, Jia-Ju Mo, Aiqing Li.
      Background: Uremic cardiomyopathy is commonly presented in chronic kidney disease (CKD), and it severely affects the prognosis of patients with CKD. In the past few decades, the investigation of uremic cardiomyopathy has developed rapidly. However, no report has summarized the situation of uremic cardiomyopathy research to date. This study aimed to evaluate the state of uremic cardiomyopathy research in the last 30 years and identify important topics and achievements, as well as emerging trends through bibliometric analysis.Materials and Methods: Publications related to uremic cardiomyopathy were collected from Science Citation Index Expanded. HistCite, VOSviewer, CiteSpace, and the Bibliometrix Package were used for bibliometric analysis and visualization, including the analysis of the overall distribution of the annual publication, leading countries, and active institutions and authors, core journals, co-cited references, and keywords.
    Results: A total of 2,403 studies related to uremic cardiomyopathy were obtained, and progress related to uremic cardiomyopathy was slower in past 3 years. A total of 10,077 authors from 2,697 institutions in 89 countries or regions reported investigations on uremic cardiomyopathy. The United States of America was the most productive and the most cited country. Myles Wolf, Joseph I Shapiro, and Carmine Zoccali published most articles in uremic cardiomyopathy, and journals in nephrology possessed core status in the field. Phosphate metabolism was the hotspot in uremic cardiomyopathy research in recent years, and future progress may concentrate on phosphate metabolism, endogenous natriuretic factors, and novel biomarkers.
    Conclusion: The United States of America and European countries played central roles in uremic cardiomyopathy research, while Chinese scholars should be more involved in this field. Global publications on uremic cardiomyopathy have entered platform stage, and the fibroblast growth factor-23-klotho axis remained a hotspot in this field. Endogenous natriuretic factors and novel biomarkers may be potential directions in future investigations.

      In response to global efforts to control and exterminate infectious diseases, this study aims to provide insight into the productivity of remdesivir research and highlight future directions. To achieve this, there is a need to summarize and curate evidence from the literature. As a result, this study carried out comprehensive scientific research to detect trends in published articles related to remdesivir using a bibliometric analysis. Keywords associated with remdesivir were used to access pertinent published articles using the Scopus database. A total of 5321 research documents were retrieved, primarily as novel research articles (n = 2440; 46%). The number of publications increased exponentially from 2020 up to the present. The papers published by the top 12 institutions focusing on remdesivir accounted for 25.69% of the overall number of articles. The USA ranked as the most productive country, with 906 documents (37.1%), equivalent to one-third of the global publications in this field. The most productive institution was Icahn School of Medicine, Mount Sinai, in the USA (103 publications). The New England Journal of Medicine was the most cited, with an h-index of 13. The publication of research on remdesivir has gained momentum in the past year. The importance of remdesivir suggests that it needs continued research to help global health organizations detect areas requiring instant action to implement suitable measures. Furthermore, this study offers evolving hotspots and valuable insights into the scientific advances in this field and provides scaling-up analysis and evidence diffusion on remdesivir.

    Xiang Li, Jing Yang, Lianhua Zhang, Guangjie Jin, Li Xu, Fujin Fang, Yunhui Li, Pingmin Wei.
      In recent years, after the essential elimination of leprosy (the prevalence of which is &lt;1/100,000), the trends, research hotpots, and frontiers of leprosy research are not clear. This study provides a detailed overview of leprosy in terms of papers, journal, language, year, citations, h-index, author keywords, institution, and country through bibliometrics. The results are as follows: (1) The publication rate has increased in recent years, and 8892 papers were obtained. Most of the publications are in English, and the subject categories are mainly focused on "Dermatology." The "leprosy review" published the most significant number of papers on leprosy, followed by "Plos Neglected Tropical Disease" and "International Journal of Leprosy and Other Mycobacterial Diseases." (2) Leprosy-related research was contributed to by 24,672 authors, and the ten authors with the most significant number of publications were identified. (3) The University of London (including the London School of Hygiene and Tropical Medicine) has the highest h-index, and Fundacao Oswaldo Cruz is the most productive institution. (4) Brazil, India, the United States, the United Kingdom, and the Netherlands are the most productive countries, and the collaborative network reveals that they have established close cooperation with other countries. France has the highest average number of citations. (5) The keyword co-occurrence network identifies five highly relevant clusters representing topical issues in leprosy research (public health, leprosy vaccine, immune mechanisms, treatment, and genomics research). Overall, these results provide valuable insights for scholars, research institutions, and policymakers to better understand developments in the field of leprosy.

    Zhen He, Lei Dai, Yuyue Zuo, Yu Chen, Hongjie Wang, Hesong Zeng.
      Pulmonary arterial hypertension (PAH) is a group of devastating and progressive disorders, resulting in relentless increases in pulmonary vascular resistance. The number of studies related to PAH has been increasing in recent years. Our study aims to illustrate trends in PAH research over the past decade using bibliometric analysis. Science Citation Index-Expanded was adopted to search studies concerning PAH between 2011 and 2020. The bibliographic information was converted and analyzed automatically using a bibliometric package in R software and citespace. The annual quantity of publications on PAH showed an overall increase last decade. The United States was the most prolific country with 2,479 publications, and it was also the country that cooperated most with other countries. Hôpital Bicêtre made important research achievements on PAH and was a leader in study cooperation. Marc Humbert led the PAH field by publishing 150 articles in the past decade. During the past decade, there was a close transnational relation among countries or regions, institutions and authors. Further, Circulation was the most cited journal, followed by the Journal of the American College of Cardiology and the American Journal of Respiratory and Critical Care Medicine, with 3,895, 3,406, and 3,170 citations, respectively. The global research status and trend of PAH are deeply understood for the first time using bibliometric and visual methods, and the results of our study bring us a valuable reference for clinical researchers.

      Ventricular remodeling is the progressive pathologic change of the original substance and morphology of the ventricle caused by various injuries and has attracted increasing attention in the past decade. This study aims to conduct a bibliometric analysis of articles on ventricular remodeling published in the Web of Science Core Collection database from 2012 to 2022 to understand the current research state in the field of ventricular remodeling and provide insights for clinicians and researchers. As a result, a total of 1710 articles on ventricular remodeling were included. Annual publications have been gradually increasing and have remained at a high level over the past ten years. The United States of America contributed the most publications, followed by China. Circulation was the most mainstream and authoritative journal focusing on ventricular remodeling. Research hotspot analysis suggested that myocardial infarction was the primary risk factor for ventricular remodeling, and emerging risk factor studies have focused on pulmonary hypertension, aortic stenosis, and diabetes. The mechanisms in the pathogenesis of ventricular remodeling were mainly closely associated with inflammation, apoptosis, oxidative stress, and myocardial fibrosis. Intensive investigation of the interactions between different mechanisms might be a future research direction. In terms of treatment, cardiac resynchronization therapy was a hot topic of research. These findings can help researchers grasp the research status of ventricular remodeling and determine future research directions.

    Comparison of citation rates between Covid-19 and non-Covid-19 articles across 24 major scientific journals.
    Michael D Brandt, Sherief A Ghozy, David F Kallmes, Robert J McDonald, Ramanathan D Kadirvel.
      Covid-19 has been front and center in the global landscape since the beginning of 2020. In response, the scientific field has dedicated enormous amounts of resources to researching the virus and its effects. The number of times Covid-19 publications are being cited throughout the literature appears remarkably high but has not been directly compared to non-Covid-19 papers in the same journals over an extended period. In our study, we use Clarivate's Web of Science-Science Citation Index Expanded™ database to identify Covid-19 papers published in 24 major scientific journals over a period of 24 months from January 1, 2020 to December 31, 2021. We conduct our search using keywords "Covid-19", "coronavirus", and "sars-cov-2" to locate publications with these words in the title. We then quantify the number of citations these papers have received and compare rates to non-Covid-19 papers in the same journals over the same timeframe. We find that, across 24 open-access and subscription-based scientific journals, Covid-19 papers published in the past 2 years currently have a median citation rate of 120.79 compared to 21.63 for non-Covid-19 papers. When negative binomial regression is used to minimize the influence of other variables such as article number variation and field of research, Covid-19 papers have still experienced more than 80% increase in citations relative to non-Covid-19 papers. These novel findings demonstrate that Covid-19 papers are being cited at remarkably higher rates than non-Covid-19 articles contained within the same journals. This suggests that journal impact factor, which is a product of the number of citations that recently published articles receive, will likely be drastically influenced by the number of Covid-19 papers that a journal has included within its pages in the previous years.

      PURPOSE: This study aimed to examine India's orthopaedic research output during 2002-2021 to analyze the research characteristics and publication performances of leading organizations, authors, and cities, the core journals publishing research, broad subject areas, sub-specialties, and the classification by anatomical location, the subject areas of research using major keywords and the sources of funding and the extent of international collaboration.METHODS: India's orthopaedic publications data was identified and downloaded from the Scopus database ( https://www.scopus.com ) using a well-defined search strategy and keywords.
    RESULTS: India's 4606 publications grew at a 20.8% annual growth rate and averaged 11.3 citations per paper. The 10.4% and 16.3% share of India's papers received external funded support and were involved in international collaboration. The USA and UK (31.8% and 21.3%) represent the highest collaborative share in India's international collaborative publications. AIIMS-New Delhi and PGIMER-Chandigarh produced a larger proportion of articles (5.2% and 4.3%) among contributing organizations. In terms of authors, R. Vaishya and S. Rajasekaran are the most productive ones, contributing 1.6% and 1.1% share respectively. Clinical studies, paediatric sub-specialty, and knee & leg anatomical location accounted for the largest share of papers (32.2%, 10.8%, and 7.5%).The most frequent keywords co-occurrences were "Orthopaedic Surgery," "Hydroxyapatite," "Biocompatibility," "Orthopaedic Procedures," "Bone," "Surgical Techniques," "Biomaterials," and "Osteosynthesis."
    CONCLUSION: This study revealed the characteristics and trends of research and core publications from Indian authors and organizations identified in the last two decades. This research should provide useful insights into the research hotspots of India in the present, past, and future.

    [CiteSpace-Based Analysis of Hot Research Topics and Frontiers of Preclinical Dentistry Education].
    Si-Yi Zhu, Di Fu, Jun Liu, Ga Liao, Ling Zou.
      Objective: To analyze the hot research topics and frontiers of preclinical dentistry education with bibliometric methods.Methods: We launched searches in the Web of Science Core Collection database to find relevant literature on preclinical dentistry education, with the time frame of the searches limited between the creation of the database and January 1, 2022. After data extraction, we used the CiteSpace software to conduct visualized analysis of a number of factors, including the number of publications, countries, institutions, authors, keywords, etc.
    Results: A total of 322 articles and reviews were included in the study, and the annual publication volume showed a trend of steady growth in the past decade. With 98 papers, the United States had the most number of published papers. The United States and the United Kingdom were important countries in the national cooperation network. There were 10 institutions that published more than 5 articles. The total number of authors of the papers covered in the study was as many as 410. One author published 4 articles and was the most published author among them. The hot research topics of preclinical dentistry education included computer-assisted instruction, instructional methodology, clinical skills and 3D printing. Moreover, computer-assisted instruction was the new hot issue of the past decade. Besides, technology, restoration, clinic skills and communication skills were identified as novel research frontiers.
    Conclusion: Visualized analysis of the research literature generates an intuitive understanding of hot research topics and frontiers of preclinical dentistry education, which provides references for future studies.

    Mapping of Research in the Field of Forest Therapy-Related Issues: A Bibliometric Analysis for 2007-2021.
    Xin Wang, Xiang-Fei Gong, Ke-Xin Xiong, De-Sheng Guo, Li-Jun Liu, Chia-Min Lin, Wei-Yin Chang.
      Exposure to forest environments promotes human health. The number of relevant studies in this area has increased rapidly. However, an overall review of relevant analyses from the perspectives of bibliometrics and visualization is lacking. A scientometric analysis of 2,545 publications from 2007 to 2021 via the Web of Science database was conducted to identify the knowledge structure and frontiers objectively. The publications were subsequently analyzed in terms of the distribution of journals and countries, citation bursts, major subject areas, and evolutionary stages. The findings showed that the knowledge foundation of forest therapy was multidisciplinary with most published in the fields of environmental sciences and ecology but lacking input from social disciplines. The research hotspots evolved from the early focus on individual benefits obtained from nature to increasing attention on human well-being at the social-ecological scale. More rigorous experiments with strict randomized controlled trials and blinding are needed to accommodate the trend of forest therapy toward non-pharmacological treatments. According to Shneider's four-stage theory, forest therapy research is in the third stage of the scientific research process. More future studies utilizing novel technologies and decision-making frameworks to solve practical issues are needed for introducing health into policies and promoting human well-being.

    Global Trend in the Research and Development of Acupuncture Treatment on Parkinson's Disease From 2000 to 2021: A Bibliometric Analysis.
    Xiaoping Li, Wan Wei, Yuan Wang, Qiang Wang, Zhibin Liu.
      Background: Acupuncture has been widely used in the treatment of patients with Parkinson's disease (PD) in the world. Despite we have an in-depth understanding of acupuncture in this field over the past years, there is no available literature on bibliometric analysis on the development of acupuncture on PD. This study was designed to explore the global trend in the research of acupuncture on PD in the recent 20 years by the software CiteSpace (5.8.R3) and VOSviewer (1.6.14).Methods: Publications regarding acupuncture therapy for PD from 2000 to 2021 were retrieved from the Web of Science Core Collection database. CiteSpace and VOSviewer were used to analyze the number of publications, the contribution of countries, institutions, journals, authors, references, and keywords.
    Results: A total of 217 studies were extracted from the database. The outputs of the publications in this field showed an upward trend during the past two decades. The country and institutions with the most publications in this field are China, South Korea, and the USA. They were the main contributors to the research. Kyung Hee University and Capital Medical University were the two most productive organizations. Hi-Joon Park had made the greatest contributions to the field. Evidence-based Complementary and Alternative Medicine was the most popular journals in this field. "Electroacupuncture" and "Bee venom acupuncture" were emerging research hotspots.
    Conclusion: The research on acupuncture on PD is potential. Authors from different countries/regions and organizations need to remove the language and academic barriers to enhance global cooperation and communications. Scholars in this field need to publish their research findings in high-quality journals to gain more attention worldwide. This study indicated that the mechanism leading to the non-motor symptoms of PD, the establishment of appropriate models that fully reflects the non-motor features of human PD, and the efficacy and safety of promising therapies for patients with PD will remain research frontiers in the future.

    Journal Discipline Plays a Significant Role in Academic Attention But Not in Social Media Attention in the Peripheral Nerve Literature.
    Hailey P Huddleston, Joey S Kurtzman, Jason Rahimzadeh, Steven M Koehler.
      Evaluating the impact of articles can be performed through bibliometric analysis or social media impact using the Altmetric Attention Score (AAS). The purpose of this study was to report on the social media impact of peripheral nerve studies; how article demographic factors, such as journal specialty (hand, orthopedics, plastic surgery), affect AAS; and how AAS correlates with bibliometrics, namely citation number. While orthopedic journals received the highest academic attention, there was no significant difference in social media attention between journal groups. These findings suggest AAS may be useful to authors in deciding which journal in which to pursue publication. [Orthopedics. 202x;xx(x):xx-xx.].

    Use of the bibliometric in rare diseases: taking Wilson disease personally.
    Lin Chen, Zhuoqi Lou, Yangxin Fang, Liya Pan, Jianhua Zhao, Yifan Zeng, Ying Wang, Nan Wang, Bing Ruan.
      BACKGROUND: Bibliometric have been widely applied to the evaluation of academic productivity. However, those of individuals or institutions on a specific disease have not been explored. The aim of the present study is to conduct a bibliometric analysis of particular rare disease and investigate whether those doctors and hospitals with higher index screened by this method specialize in this disease.METHODS: A representative rare disease, Wilson disease (WD), was searched on Clarivate Analytics' Web of Science and Elsevier's Scopus, which was published in English between 1 January 2001 and 31 December 2020. Clinical authors and medical institutions with the most papers were screened, and their total number of publications and citations, h-index and g-index were computed and then ranked by h-index.
    RESULTS: A total of 6856 and 6193 papers and 200 and 160 authors were got from WoS and Scopus, respectively. Scopus provided 160 institutions. The above bibliometric indices were calculated in 100 researchers and 80 institutions, and top 30 authors (Top-30a) and top 20 institutions (Top-20i) of them based on the h-index were listed in the tables. Top-30a came from seven specialties and 13 countries whose median (interquartile range) h-index was 14 (12-19.5) (range 10-28) which was located between associate and full professors in some other disciplines. Top-20i was distributed in 13 countries whose mean ± standard deviation of the h-index was 15 ± 4.9 (range 10-27).
    CONCLUSIONS: The related specialists and medical institutions of WD screened by specific disease bibliometric analysis are eminent and credible and benefit WD patients to obtain reliable medical treatment. This model may be suitable for other rare diseases.

    Female Representation in Academic Medicine in Pakistan: A 15-Year Overview.
    Samina Ismail, Fiza Khan, Malika Hameed.
      OBJECTIVE: To determine the proportion of female authors publishing in Pakistan and their representation in academic anesthesiology. Design, place, and duration of study: This study was a cross-sectional retrospective analysis. We reviewed all volumes and issues of the Journal of the College of Physicians and Surgeons Pakistan (JCPSP) published from 2007 to 2021. All original articles, clinical practice articles (CPAs), reviews, and editorials were included. The first and last authors publishing in JCPSP were the study subjects.MAIN OUTCOME MEASURES: Gender of the first and last authors was determined by (a) a general review of the author's first, middle, and last names, (b) an internet search of the author's name, and a review of photographs on their social media, or (c) an online search of the author's first name for typical gender assignment. The research field of the first author was noted to determine the contribution of different medical specialties. Article type and the number of citations were noted to determine the relationship with the gender of the author.
    RESULTS: Around 1549 papers were published by Pakistani authors, of which, 82.6% were original articles, 9.8% were editorials, 5.5% were CPAs, and 2.1% were reviews. Around 56.2% of the first authors and 70.9% of the last authors were males. Most article types had a majority of male first and last authors (<0.001). The median (interquartile range) citation rate was two (0-19), with no difference in citations between gender. Male-male author pairing remained the most common (45.6%). The majority of the papers published belonged to the field of medicine (27.2%) and surgery (21%), with only 3.1% contributed by anesthesiology (females: 41.3%; males: 58.6%).
    CONCLUSION: Female representation in academia in Pakistan is at par with developed countries. The academic contribution from anesthesiology remains low, which corresponds to a lower percentage of the anesthesia workforce in the country. There is a need for a national indexed journal of anesthesia to evaluate the true representation of female authors in the country.

    A Bibliometric Review on Gut Microbiome and Alzheimer's Disease Between 2012 and 2021.
    Alejandro I Trejo-Castro, Diego Carrion-Alvarez, Antonio Martinez-Torteya, Claudia Rangel-Escareño.
      Research on the microbiome has drawn an increasing amount of attention over the past decade. Even more so for its association with disease. Neurodegenerative diseases, such as Alzheimer's disease (AD) have been a subject of study for a long time with slow success in improving diagnostic accuracy or identifying a possibility for treatment. In this work, we analyze past and current research on microbiome and its positive impact on AD treatment and diagnosis. We present a bibliometric analysis from 2012 to 2021 with data retrieved on September 2, 2021, from the Scopus database. The query includes "Gut AND (Microbiota OR Microbiome) AND Alzheimer*" within the article title, abstract, and keywords for all kinds of documents in the database. Compared with 2016, the number of publications (NPs) on the subject doubled by 2017. Moreover, we observe an exponential growth through 2020, and with the data presented, it is almost certain that it will continue this trend and grow even further in the upcoming years. We identify key journals interested in the subject and discuss the articles with most citations, analyzing trends and topics for future research, such as the ability to diagnose the disease and complement the cognitive test with other clinical biomarkers. According to the test, mild cognitive impairment (MCI) is normally considered an initial stage for AD. This test, combined with the role of the gut microbiome in early stages of the disease, may improve the diagnostic accuracy. Based on our findings, there is emerging evidence that microbiota, perhaps more specifically gut microbiota, plays a key role in the pathogenesis of diseases, such as AD.

    Global Trends in Natural Biopolymers in the 21st Century: A Scientometric Review.
    Yitao Sun, Yinping Bai, Wenlong Yang, Kangmin Bu, Sikander Khan Tanveer, Jiangbo Hai.
      Since the 21st century, natural biopolymers have played an indispensable role in long-term global development strategies, and their research has shown a positive growth trend. However, these substantive scientific results are not conducive to our quick grasp of hotspots and insight into future directions and to understanding which local changes have occurred and which trend areas deserve more attention. Therefore, this study provides a new data-driven bibliometric analysis strategy and framework for mining the core content of massive bibliographic data, based on mathematical models VOS Viewer and CiteSpace software, aiming to understand the research prospects and opportunities of natural biopolymers. The United States is reported to be the most important contributor to research in this field, with numerous publications and active institutions; polymer science is the most popular subject category, but the further emphasis should be placed on interdisciplinary teamwork; mainstream research in this field is divided into five clusters of knowledge structures; since the explosion in the number of articles in 2018, researchers are mainly engaged in three fields: "medical field," "biochemistry field," and "food science fields." Through an in-depth analysis of natural biopolymer research, this article provides a better understanding of trends emerging in the field over the past 22 years and can also serve as a reference for future research.

    Comparison of scientometric achievements at PhD and scientific output ten years later for 4,790 academic researchers.
    Gyöngyi Munkácsy, Péter Herman, Balázs Győrffy.
      INTRODUCTION: PhD is the highest awarded degree offered by universities in different disciplines. Owners of a PhD can teach at universities, start independent research and receive a higher salary while further building a scientific career. We examined whether the publication output before the PhD degree has a correlation with subsequent research activities.METHODS: We downloaded publication and citation data from the Hungarian Scientific Bibliography for Hungarian researchers who obtained PhD between the ages of 24 and 45. The researchers were grouped into eleven scientific sections. We examined the number of Q1 publications published in the previous 5 years, the H-index, the total number of citations for the last complete year, and the biological age of the researcher. Each parameter was computed for the year at which the PhD was obtained and ten years later. Pre-PhD publications (and citations for these) were excluded when assessing post-PhD track records. Spearman rank correlation and Kruskal-Wallis test were computed.
    RESULTS: We analyzed all together 4,790 researchers. We obtained a positive correlation between the number of Q1 publications before and after PhD (corr. coeff. = 0.21-0.54, p<0.01 in all sections), between the H-index before and after PhD (corr. coeff. = 0.32-0.56, p<0.01 in all sections), and between the citations received before and after PhD (corr. coeff. = 0.34-0.51, p<0.01 in all sections). All three metrics measured ten years after the PhD were negatively correlated with the age of the researcher at the time of obtaining the PhD (number of publications corr. coeff. = -0.09-0.22, p<0.05; H-index corr. coeff. = -0.09-0.29, p<0.08; number of citations corr. coeff. = -0.14-0.30, p<0.01). Among all disciplines, Philosophy and History and Engineering sciences show the strongest correlation between pre- and post-PhD output. When running multiple regression analysis for all three metrics as dependent variables and the number of articles, the H-index, the number of citations in the year of the PhD, the calendar year of PhD, and the gender of the researcher as independent variables, the number of articles and the H-index in the year of PhD reached the strongest positive correlations while gender had a negative correlation.
    CONCLUSIONS: We independently evaluated pre- and post-PhD publication performance. In connection with age, the discipline-specific reference values of scientometric parameters at the time of obtaining the PhD can help to select candidates for postdoctoral grants and positions.

    Bibliometric Analysis of Trends in Mulberry and Silkworm Research on the Production of Silk and Its By-Products.
    Domenico Giora, Giuditta Marchetti, Silvia Cappellozza, Alberto Assirelli, Alessio Saviane, Luigi Sartori, Francesco Marinello.
      Traditionally, sericulture is meant as the agricultural activity of silk production, from mulberry (Morus sp.pl.) cultivation to silkworm (Bombyx mori L.) rearing. The aim of the present work is to analyze the trends and outputs of scientific research on sericulture-related topics during the last two decades, from 2000 to 2020. In this work the authors propose a text-mining analysis of the titles, abstracts and keywords of scientific articles focused on sericulture and available in the SCOPUS database considering the above-mentioned period of time; from this article collection, the 100 most recurrent terms were extracted and studied in detail. The number of publications per year in sericulture-related topics increased from 87 in 2000 to 363 in 2020 (+317%). The 100 most recurrent terms were then aggregated in clusters. The analysis shows how in the last period scientific research, besides the traditional themes of sericulture, also focused on alternative products obtainable from the sericultural practice, as fruits of mulberry trees (increment of +134% of the occurrences in the last five years) and chemical compounds as antioxidants (+233% of occurrences), phenolics (+330% of occurrences) and flavonoids (+274% of occurrences). From these considerations, the authors can state how sericulture is an active and multidisciplinary research field.

    Bibliometric Analysis of the Knowledge Base and Future Trends on Sarcopenia from 1999-2021.
    Yao Xiao, Ziheng Deng, Hangjing Tan, Tiejian Jiang, Zhiheng Chen.
      Sarcopenia is characterized by progressive loss of muscle mass and function, and it is becoming a serious public health problem with the aging population. However, a comprehensive overview of the knowledge base and future trends is still lacking. The articles and reviews with "sarcopenia" in their title published from 1999 to 2021 in the SCIE database were retrieved. We used Microsoft Excel, VOSviewer, and CiteSpace to conduct a descriptive and bibliometric analysis. A total of 3582 publications were collected, from 4 published in 2000 increasing dramatically to 850 documents in 2021. The USA was the most productive country, with the most citations. The Catholic University of the Sacred Heart and Landi F were the most influential organization and author in this field, respectively. The core journal in this field was the Journal of Cachexia Sarcopenia and Muscle. According to the analysis of keywords and references, we roughly categorized the main research areas into four domains as follows: 1. Definition and diagnosis; 2. Epidemiology; 3. Etiology and pathogenesis; 4. Treatments. Comparing different diagnostic tools and the epidemiology of sarcopenia in different populations are recent hotspots, while more efforts are needed in the underlying mechanism and developing safe and effective treatments. In conclusion, this study provides comprehensive insights into developments and trends in sarcopenia research that can help researchers and clinicians better manage and implement their work.

      Fluoridated-milk schemes have been developed and implemented in many countries to prevent dental caries. This study aimed to evaluate the impact/influence of scientific publications, researchers, and institutions conducting research on milk fluoridation; to explore the international and inter-institutional collaboration and illustrate scientific output trends; and to pinpoint research hotspots in milk fluoridation research. This bibliometric analysis of original research articles on milk fluoridation includes all of the original articles published in peer-reviewed journals systematically extracted from the SCOPUS database. In total, 108 articles were included in this study, with a total of 11,789 citations. A majority (67.6%) of these articles were in the subject area of 'dentistry', 22.2% externally funded, 14.8% published in the journal, Caries Research, 7.4% authored/co-authored by Twetman S, 6.5% by authors from Universidad de Chile, and the UK had the highest output (24.1%). The network visualizations showed that those countries with current/past histories of implemented milk fluoridation programs were interconnected on the network visualization map, and they were predominantly the hotspots for original research on milk fluoridation. This study also identified inequalities in research outputs on the topic. With the current enormous global burden of dental caries in children, particularly in low- and middle-income countries, there is an urgent need for greater and more equitable funding of milk fluoridation research globally.

    Metal-Organic Frameworks for Wastewater Decontamination: Discovering Intellectual Structure and Research Trends.
    Muhammad Nihal Naseer, Juhana Jaafar, Hazlina Junoh, Asad A Zaidi, Mahesh Kumar, Ali Alqahtany, Rehan Jamil, Saleh H Alyami, Naief A Aldossary.
      Due to their simple synthesis method and excellent properties, such as superior adsorption and regeneration capabilities, with a large surface area and tunable pores, metal-organic frameworks (MOFs) have emerged as a suitable option for wastewater treatment. Although an exponential growth in MOF literature has been observed in recent years, conducting a quantitative literature analysis of MOF application in wastewater treatment is a novelty. To fill this gap, a total of 1187 relevant publications were extracted from the Web of Science, published during the last 50 years, and analyzed using bibliometric and content analysis techniques. A bibliometric analysis was conducted to reveal growing publication trends, leading journals, prolific countries, and organizations; whereas, a content analysis was used to highlight key research themes and hot topics in this field. The analyses revealed that there is a strong international collaboration among authors, countries, and organizations. Chemical Engineering Journal, Journal of Hazardous Materials, and Journal of Environmental Chemical Engineering are the most prolific journals in this field. Furthermore, the use of MOFs for removing antibiotics from wastewater was identified as a recent hot topic. In addition, performance enhancements of MOFs, in terms of a higher adsorption capacity and water stability, were identified as topics of great interest. To cater to these issues, the application of graphene, graphene oxides, nanoparticles, and quantum dots was also observed in the research fronts in this field.

      BACKGROUND: To inform training program development and curricular initiatives, quantitative descriptions of the disciplinary training of research teams publishing in top-tier clinical and epidemiological journals are needed. Our objective was to assess whether interdisciplinary academic training and teamwork of authors publishing original research in 15 top-tier journals varied by year of publication (2000/2010/2020), type of journal (epidemiological/general clinical/specialty clinical), corresponding author gender, and time since the corresponding author completed formal training relative to the article publication date (<5/≥5 years).METHODS AND FINDINGS: We invited corresponding authors of original research articles to participate in an online survey (n = 103; response rate = 8.3% of 1240 invited authors). In bivariate analyses, year of publication, type of journal, gender, and recency of training were not significantly associated with interdisciplinary team composition, whether a co-author with epidemiological or biostatistical training was involved in any research stage (design/analysis/interpretation/reporting), or with participants' confidence in their own or their co-authors epidemiological or biostatistical expertise (p > 0.05 for each comparison). Exceptions were participants with more recent epidemiological training all had co-author(s) with epidemiological training contribute to study design and interpretation, and participants who published in 2020 were more likely to report being extremely confident in their epidemiological abilities.
    CONCLUSIONS: This study was the first to quantify interdisciplinary training among research teams publishing in epidemiological and clinical journals. Our quantitative results show research published in top-tier journals generally represents interdisciplinary teamwork and that interdisciplinary training may provide publication type options. Our qualitative results show researchers view interdisciplinary training favorably.

    Global trends and prospects of blue carbon sinks: a bibliometric analysis.
    Lu Jiang, Tang Yang, Jing Yu.
      Blue carbon sinks (mangroves, saltmarshes, and seagrasses) are considered an effective nature-based approach for climate change mitigation. Despite growing interest, a systematic review of this topic is still scarce. This study evaluated 1348 blue carbon sink-related articles from 1990 to 2020 using bibliometric technology. The results from total of 85 countries, 1538 institutions, and 4492 authors indicated that blue carbon sink research shows the characteristics of rapid growth. The most active country, institution, and author were USA, Chinese Academy of Sciences, and Duarte C.M., respectively. Relatively close academic collaboration has formed in blue carbon science. Environmental Sciences was the most popular category with 590 papers. The percentages of articles related to mangroves, saltmarshes, and seagrasses were 63.87%, 40.36%, and 40.65%, respectively. Mangrove carbon sinks are the most popular topic, and stable isotope and remote sensing are the most researched technologies for mapping and quantifying blue carbon sinks. The threats to blue carbon sinks are complex and distinctive. Restoration, conservation, and management of blue carbon ecosystems aimed to improve their carbon sink capacity are becoming hot issues and should be further investigated in the future. These findings provide a scientific roadmap for further research in this field and will enable stakeholders to identify the research trend.

    Ranking of addiction journals in eight widely used impact metrics.
    Dennis M Gorman, Chuck Huber.
      Background and aims: Journal metrics assess impact upon the research literature, and are now used to assess individual researchers in hiring and promotion decisions. This study compared the ranking of addiction journals according to eight widely used metrics; assessed the correlations between journal rankings; and assessed changes over time in metric scores.Methods: Data pertaining to the 2020 scores on eight metrics for 43 journals were obtained and the top 20 ranking in each compared and the correlations between rankings assessed. The Impact Factor was employed to assess changes over time.
    Results: Ignoring the two categorization systems used by some metrics, 31 journals appeared in at least one metric top 20 and 11 in all eight. The top rank in each was occupied by one of three journals. Three-quarters of the correlations between rankings were above 6.0. The number of journals with an Impact Factor rose from 23 in 1997 to 38 in 2020, and the journals added tended to focus on addictions other than alcohol and drugs or have a specific focus.
    Conclusions and discussion: The results indicate a concentration of journals at the top of the metrics and moderate to strong agreement between them, but almost three-quarters of journals appeared in at least one metric. The longitudinal data reflect both a broadening and specialization of the addiction field. The study limitations include exclusion of some journals and metrics.

    R Iping, J M Hulst, K F M Joosten.
      BACKGROUND & AIMS: Pediatric intensive care nutrition is a growing research field on the intersection of three large research domains: Pediatrics, Critical Care Medicine and Nutrition & Dietetics. This study, using Research Intelligence tools, such as bibliometric network visualization software, was designed to map the developments in research topics and collaboration in the field over the past thirty years, and discuss how these developments align with recent recommendations and guidelines of the active expert groups in the field.METHODS: We searched the Web of Science Core Collection for relevant full articles, reviews, letters and proceedings papers. To describe the research field a search strategy was iteratively designed based on the combinations of relevant key words. The articles the were found were processed using software designed for bibliometric network mapping. Filters were applied to select only the most relevant articles for the field.
    RESULTS: The resulting visualizations show the network of researchers active in the field of pediatric intensive care nutrition, and the collaborations between them. Using the most frequently used key terms a map was created to show the most prominent research areas within the field, and the development of attention for these topics over time.
    CONCLUSIONS: The network analyses show a research field that is gaining momentum, with several cores of research activity in different institutions. Some research groups collaborate on specific topics within the field, while others seem to be more isolated. The analyses uncover the potential for future collaborations and emerging topics of attention in the different areas of research in the field. The results are compared to recent recommendations for research priorities by active networks in the field. We discuss similarities and discrepancies.

    Scientific collaboration, research funding, and novelty in scientific knowledge.
    Hyunha Shin, Keungoui Kim, Dieter F Kogler.
      Disruptive advancements in science and technology often rely on new ideas and findings, which in turn brings us to focus on the value of novelty in scholarly activities. Using Web of Science publication data from European regions for the period between 2008 and 2017, this study examines, first, the impact of scientific collaboration on novelty of research. Here, five levels of collaboration are considered for each article-country, three levels of regions, and institutions, and novelty is measured with keywords information. Second, we investigate both the effect and moderating effect of research funding on novelty. Our findings show that there is a negative and significant relationship between scientific collaboration and novelty. Furthermore, funded papers show lower novelty than the unfunded, but funding does have a significant moderating effect on the relationship between collaboration and novelty. This study contributes by linking diverse levels of collaboration and funding sources to article's novelty and thus extending the scope of bibliometric research of publications.

    Emerging Trends and Hotspots in Tai Chi Fall Prevention: Analysis and Visualization.
    Jiesi Chen, Xin Xue, Jing Xu, Jinshu Zeng, Fei Xu.
      Recently, substantial studies have increased around the topic of the tai chi fall-prevention field. Few studies, however, have revealed the current progress and hotspots under a bibliometric analysis. Therefore, the present study aimed to conduct Citespace, a significant application for bibliometric analysis, to carry out the situation and trend in this field. This study has identified the core countries are the United States, China, Australia, and England, which are also the origins of the core institutions. Besides this, we also have found two large research groups led by Li and Sherrington. Moreover, the result has revealed that J Aging Phys Act and J Am Geriatr Soc are the primary journals. Geriatrics and gerontology, sport sciences, rehabilitation, and gerontology are the leading categories. Furthermore, one of the more important findings to come out in this study are that "elderly", "Parkinson's disease", "vestibular rehabilitation", "frail patient", and "community fall prevention" are the research hotspots. "Women", "proprioception", "cognitive impairment", "dementia", "osteoarthritis", and "stroke" are the potential research trend in the future. These findings suggest that the tai chi fall-prevention field has a broad research prospect. Although several questions remain uncertain currently, it is worthy for scholars to do further study.

    A Bibliometric Analysis of Research Publications of the Bucharest University of Economic Studies in Time of Pandemics: Implications for Teachers' Professional Publishing Activity.
    Adriana Ana Maria Davidescu, Margareta-Stela Florescu, Liviu Cosmin Mosora, Mihaela Hrisanta Mosora, Eduard Mihai Manta.
      The epidemic has forced the academic world, regardless of nation of origin, to unify to find a response to the economic and social difficulties we confront as quickly as possible. This paper investigates how academic performance in terms of scientific publications, especially during the pandemic period, may constitute the premises for boosting professional well-being. The analysis focuses on the researchers and professors of the Bucharest Academy of Economic Studies, analysing in a comparative way the academic performance during the pandemic as a fundamental side of their professional career. To do that, two samples of scientific publications collected between January 2020 and December 2021 were investigated. The first sample comprised 1411 documents indexed in the WoS database, while the second one was formed by 876 documents indexed in the Scopus database. All samples were published during the pandemic and have the university's affiliation. The empirical findings indicated that the pandemic has created a boost in the number and quality of medical publications for the professors at the Bucharest University of Economic Studies. They created new multidisciplinary teams (economics and medicine), strengthening and widening national and international collaborations.

    A Scientometric Review on Mapping Research Knowledge for 3D Printing Concrete.
    Chuan He, Shiyu Zhang, Youwang Liang, Waqas Ahmad, Fadi Althoey, Saleh H Alyami, Muhammad Faisal Javed, Ahmed Farouk Deifalla.
      The scientometric analysis is statistical scrutiny of books, papers, and other publications to assess the "output" of individuals/research teams, organizations, and nations, to identify national and worldwide networks, and to map the creation of new (multi-disciplinary) scientific and technological fields that would be beneficial for the new researchers in the particular field. A scientometric review of 3D printing concrete is carried out in this study to explore the different literature aspects. There are limitations in conventional and typical review studies regarding the capacity of such studies to link various elements of the literature accurately and comprehensively. Some major problematic phases in advanced level research are: co-occurrence, science mapping, and co-citation. The sources with maximum articles, the highly creative researchers/authors known for citations and publications, keywords co-occurrences, and actively involved domains in 3D printing concrete research are explored during the analysis. VOS viewer application analyses bibliometric datasets with 953 research publications were extracted from the Scopus database. The current study would benefit academics for joint venture development and sharing new strategies and ideas due to the graphical and statistical depiction of contributing regions/countries and researchers.

    Mapping the Knowledge of Antipsychotics-Induced Sudden Cardiac Death: A Scientometric Analysis in CiteSpace and VOSviewer.
    Min Wang, Yixun Ma, Zefang Shen, Lufang Jiang, Xiaoyuan Zhang, Xuan Wei, Zhengqi Han, Hongxia Liu, Tiantong Yang.
      The drugs on the market for schizophrenia are first-generation and second-generation antipsychotics. Some of the first-generation drugs have more side effects than the other drugs, so they are gradually no longer being applied clinically. Years of research have shown that the risk of sudden cardiac death in psychotic patients is associated with drug use, and antipsychotic drugs have certain cardiotoxicity and can induce arrhythmias. The mechanism of antipsychotic-induced sudden cardiac death is complicated. Highly cited papers are among the most commonly used indicators for measuring scientific excellence. This article presents a high-level analysis of highly cited papers using Web of Science core collection databases, scientometrics methods, and thematic clusters. Temporal dynamics of focus topics are identified using a collaborative network (author, institution, thematic clusters, and temporal dynamics of focus topics are identified), keyword co-occurrence analysis, co-citation clustering, and keyword evolution. The primary purpose of this study is to discuss the visual results, summarize the research progress, and predict the future research trends by bibliometric methods of CiteSpace and VOSviewer. This study showed that a research hotspot is that the mechanisms of cardiotoxicity, the safety monitoring, and the assessment of the risk-benefit during clinical use of some newer antipsychotics, clozapine and olanzapine. We discussed relevant key articles briefly and provided ideas for future research directions for more researchers to conduct related research.

    Tungsten-based Nanomaterials in the Biomedical Field: A Bibliometric Analysis of Research Progress and Prospects.
    Chenglu Gu, Zhiqiang Wang, Yawen Pan, Shuang Zhu, Zhanjun Gu.
      Tungsten-based nanomaterials (TNMs) with diverse nanostructures and unique physicochemical properties have been widely applied in the biomedical field. Although various reviews have described the application of TNMs in specific biomedical fields, there are still no comprehensive studies that summarize and analyze research trends of the field as a whole. To identify and further promote the development of biomedical TNMs, a bibliometric analysis method was used to analyze all relevant literature on this topic. First, general bibliometric distributions of the dataset by year, country, institute, referenced source and research hotspots are recognized. Next, we provide a comprehensive review of the subjectively recognized research hotspots in various biomedical fields, including biological sensing, anticancer treatments, antibacterials, and toxicity evaluation. Finally, the prospects and challenges of TNMs are discussed to provide a new perspective for further promoting their development in biomedical research. This article is protected by copyright.

    Knowledge Domain and Emerging Trends of Social Vulnerability Research: A Bibliometric Analysis (1991-2021).
    Hua Li, Weijun Wang.
      Carrying out social vulnerability research has become an important way to understand the sustainable development of resources, the environment, populations, and societies. Clarifying the research context and development trend of social vulnerability is of great significance to the follow-up theoretical research on and practical exploration of sustainable social development. With the help of a CiteSpace knowledge map analysis, this study reveals the research hotspots and their evolution in different periods and puts forward the key problems in and future direction of social vulnerability research in the future. This study found that the number of articles on social vulnerability research showed a steady upward trend and that the research experienced roughly three stages: an embryonic stage, a development stage, and a stable stage. The United States, Brazil, the United Kingdom, and China accounted for the majority of the research, but the intensity of cooperation between them is still weak. Vulnerability assessment and risk assessment in the context of policy and environmental change are hot topics in the current research. In the future, it is necessary to focus on the comprehensive research on the integrated and cross-scale research on social vulnerability, research on its occurrence and evolution, and on the dynamic monitoring as well as optimal regulation of social vulnerability under multiple pressures.

    Trends on CO2 Capture with Microalgae: A Bibliometric Analysis.
    Alejandra M Miranda, Fabian Hernandez-Tenorio, David Ocampo, Gabriel J Vargas, Alex A Sáez.
      The alarming levels of carbon dioxide (CO2) are an environmental problem that affects the economic growth of the world. CO2 emissions represent penalties and restrictions due to the high carbon footprint. Therefore, sustainable strategies are required to reduce the negative impact that occurs. Among the potential systems for CO2 capture are microalgae. These are defined as photosynthetic microorganisms that use CO2 and sunlight to obtain oxygen (O2) and generate value-added products such as biofuels, among others. Despite the advantages that microalgae may present, there are still technical-economic challenges that limit industrial-scale commercialization and the use of biomass in the production of added-value compounds. Therefore, this study reviews the current state of research on CO2 capture with microalgae, for which bibliometric analysis was used to establish the trends of the subject in terms of scientometric parameters. Technological advances in the use of microalgal biomass were also identified. Additionally, it was possible to establish the different cooperation networks between countries, which showed interactions in the search to reduce CO2 concentrations through microalgae.

    A Bibliometric Analysis of Research Progress and Trends on Fly Ash-Based Geopolymer.
    Quanzhi Tian, Yinhai Pan, Yingchu Bai, Shuo Yao, Shiqiang Sun.
      The objective of this work is to present the research progress and applications of fly ash-based geopolymer, and summarize the future research hotpots. Since 1998, scholars have made important contributions to the study of fly ash-based geopolymer, and a large number of research studies have been published. Therefore, a bibliometric analysis for the determination of the research status, trend, and history of fly ash-based geopolymer was conducted in the present study. A total of 4352 publications on fly ash-based geopolymer were collected between 1998 and 2022, with an increasing trend year by year. China and Australia are the largest contributors to the field, and the research institutions in each country cooperate closely. In addition, the most contributing research areas are MATERIALS SCIENCE, ENGINEERING, and CONSTRUCTION & BUILDING TECHNOLOGY. The keywords including fly ash, compressive strength, and mechanical property are the most frequently appearing words. On the whole, the development of fly ash-based geopolymer could be divided into three stages including the replacement of ordinary Portland cement, the development of multifunctional materials, and the reduction of environmental impact by the conversion of solid waste. This overview could provide an important guidance for the development of fly ash-based geopolymer.

    The Core of Healthcare Efficiency: A Comprehensive Bibliometric Review on Frontier Analysis of Hospitals.
    Thyago Celso Cavalcante Nepomuceno, Luca Piubello Orsini, Victor Diogho Heuer de Carvalho, Thiago Poleto, Chiara Leardini.
      Parametric and non-parametric frontier applications are typical for measuring the efficiency and productivity of many healthcare units. Due to the current COVID-19 pandemic, hospital efficiency is the center of academic discussions and the most desired target for many public authorities under limited resources. Investigating the state of the art of such applications and methodologies in the healthcare sector, besides uncovering strategical managerial prospects, can expand the scientific knowledge on the fundamental differences among efficiency models, variables and applications, drag research attention to the most attractive and recurrent concepts, and broaden a discussion on the specific theoretical and empirical gaps still to be addressed in future research agendas. This work offers a systematic bibliometric review to explore this complex panorama. Hospital efficiency applications from 1996 to 2022 were investigated from the Web of Science base. We selected 65 from the 203 most prominent works based on the Core Publication methodology. We provide core and general classifications according to the clinical outcome, bibliographic coupling of concepts and keywords highlighting the most relevant perspectives and literature gaps, and a comprehensive discussion of the most attractive literature and insights for building a research agenda in the field.

    Recruitment of women in neurosurgery: a 7-year quantitative analysis.
    James Feghali, Albert Antar, Elizabeth E Wicks, Shahab Aldin Sattari, Sean Li, Timothy F Witham, Henry Brem, Judy Huang.
      OBJECTIVE: The authors aimed to characterize which US medical schools have the most female neurosurgery residents and to identify potential associations between medical school characteristics and successful recruitment of women pursuing a neurosurgery career.METHODS: The authors evaluated a total of 1572 residents in US neurosurgery programs accredited by the Accreditation Council for Graduate Medical Education as of February 2021, representing match cohorts from 2014 to 2020. The authors extracted US medical school characteristics and ranked schools based on the percentages of women graduates entering neurosurgery. They additionally studied yearly trends of the percentage of women constituting incoming neurosurgery resident cohorts as well as associations between female recruitment percentage and medical school characteristics using univariable and stepwise multivariable linear regression (including significant univariable factors).
    RESULTS: The cohort consisted of 1255 male and 317 (20%) female residents. Yearly trends indicated a significant drop in incoming female residents in 2016, followed by significant increases in 2017 and 2019. On multivariable analysis, the following factors were associated with a higher average percentage of female graduates entering neurosurgery: total affiliated neurosurgery clinical faculty (β = 0.006, 95% CI 0.001-0.011, p = 0.01), allopathic versus osteopathic schools (β = 0.231, 95% CI 0.053-0.409, p = 0.01), and top 10 U.S. News & World Report ranking (β = 0.380, 95% CI 0.129-0.589, p < 0.01). When the number of female clinical faculty was added to the model, the variable was not statistically significant. Multivariable bibliometric analyses indicated a higher mean preresidency H-index for men, with an even greater gender difference identified in the 2021 H-index.
    CONCLUSIONS: This study characterizes which medical schools are most successful at recruiting female students who constituted the total neurosurgery resident workforce of the 2020-2021 academic year. The overall number of clinical neurosurgery faculty rather than faculty gender was independently associated with female recruitment. Gender differences in research productivity persisted with control for confounders and increased between preresidency and 2021 time points. Such understanding of factors that influence the recruitment of women can help improve female representation in neurosurgery residency training moving forward.

    Traits of Complex Thinking: A Bibliometric Review of a Disruptive Construct in Education.
    Jose Jaime Baena-Rojas, María Soledad Ramírez-Montoya, Diego Mauricio Mazo-Cuervo, Edgar Omar López-Caudana.
      The purpose of this research is to contextualize the behavior of publications on complex thinking in education. A total of 428 documents compiled in Scopus from 1937 to 2022 were analyzed with a bibliometric study considering criteria such as "complex thinking", "complex thought", and "reasoning for complexity", all combined with education. The results show 153, 47, and 5 publications for each criterion with their related disciplines, citations, types of documents, universities, prominent authors, researching countries, and the general diachronic evolution of the subject, this allows to establish an idea about the implications of the present study according to one of the most important databases in the world. It is concluded that complex thinking and its relationship with education awakens a greater interest in the academy, not only because of its incidence in diverse fields that are nourished by it for the generation of new multidisciplinary knowledge but also because of the published research that demonstrates its transcendence.

    Palliative Care Landscape in the COVID-19 Era: Bibliometric Analysis of Global Research.
    Hammoda Abu-Odah, Jingjing Su, Mian Wang, Sin-Yi Rose Lin, Jonathan Bayuo, Salihu Sabiu Musa, Alex Molassiotis.
      Despite the increasing number of publications globally, the COVID-19 pandemic has underscored significant research gaps that should be resolved, including within PC-related research. This study aimed to map and understand the global trends in palliative care (PC)-related COVID-19 research and provide quantitative evidence to guide future studies. We systematically searched four databases between 1st January 2020 and 25th April 2022. The VOSviewer, Gephi, and R software were utilized for data analysis and results visualization. A total of 673 articles were identified from the databases between 1st January 2020 and 25th April 2022. Canada (6.2%), Australia (5.4%), and the United Kingdom (3.8%) were the most productive countries regarding articles published per million confirmed COVID-19 cases. A lack of international collaborations and an uneven research focus on PC across countries with different pandemic trajectories was observed. The PC research in question focused on cancer, telehealth, death and dying, and bereavement. This study's conclusions support the recommendation for international collaboration to facilitate knowledge and practice transformation to support countries with unmet PC needs during the pandemic. Further studies are required on the grief and bereavement support of families, healthcare professionals and patients with other life-threatening illnesses.

    Systematic Bibliometric and Visualized Analysis of Research Hotspots and Trends on Autism Spectrum Disorder Neuroimaging.
    Yi Lu, Li Zhang, Xing-Yang Wu, Fang-Rong Fei, Hui Han.
      Background: Autism spectrum disorder (ASD) is a chronic developmental disability caused by differences in the brain. The gold standard for the diagnosis of this condition is based on behavioral science, but research on the application of neurological detection to diagnose the atypical nervous system of ASD is ongoing. ASD neuroimaging research involves the examination of the brain's structure, functional connections, and neurometabolic. However, limited medical resource and the unique heterogeneity of ASD have resulted in many challenges when neuroimaging is utilized.Objective: This bibliometric study is aimed at summarizing themes and trends in research on autism spectrum disorder neuroimaging and at proposing potential directions for future inquiry.
    Methods: Citations were downloaded from the Web of Science Core Collection database on neuroimaging published from January 1, 2012, to December 31, 2021. The retrieved information was analyzed using Bibliometric.com, CiteSpace.5.8. R3, and VOS viewer.
    Results: A total of 1,363 papers were published across 58 regions. The United States was the leading source of publications. The League of European Research Universities published the largest number of articles (171). Burst keywords from 2018 to 2021 include identification and network. The clusters of references that continued into 2020 included graph theory, functional connectivity, and classification, which represent key research topics.
    Conclusions: Imaging data is being used to identify neuro-network models with higher accuracy for ASD discrimination. Functional near-infrared imaging is advantageous compared to other neuroimaging. In the future, research on systematic and accurate computer-aided diagnosis technology should be encouraged. Moreover, the study of neuroimaging of ASD in different psychological and behavioral states can inspire new ideas about the diagnosis and intervention training of ASD and should be explored.

      5-aminolevulinic acid (5-ALA) has been extensively studied for its sustainability and broad-spectrum applications in medical research and theranostics, as well as other areas. It's a precursor of protoporphyrin IX (PpIX), a sustainable endogenous and naturally-existing photosensitizer. However, to the best of our knowledge, a scientometrics study based on the scientific knowledge assay of the overall situation on 5-ALA research has not been reported so far, which would be of major importance to the relevant researchers. In this study, we collected all the research articles published in the last two decades from the Web of Science Core Collection database and employed bibliometric methods to comprehensively analyze the dataset from different perspectives using CiteSpace. A total of 1595 articles were identified. The analysis results showed that China published the largest number of articles, and SBI Pharmaceuticals Co., Ltd. was the most productive institution that sponsored several of the most productive authors. The cluster analysis and burst detections indicated that the improvement of photodynamic efficacy theranostics is the up-to-date key direction in 5-ALA research. Furthermore, we emphatically studied nanotechnology involvement in 5-ALA delivery and theranostics research. We envision that our results will be beneficial for researchers to have a panorama of and deep insights into this area, thus inspiring further exploitations, especially of the nanomaterial-based systems for 5-ALA delivery and theranostic applications.

    Virtual Learning During the COVID-19 Pandemic: A Bibliometric Review and Future Research Agenda.
    Bilal, Eglantina Hysa, Ahsan Akbar, Fakhra Yasmin, Atteeq Ur Rahman, Shengbing Li.
      Virtual learning has emerged as a powerful platform for students and academicians in the "new normal" owing to the availability of advanced technological tools and platforms. Recently, considerable literature has grown up around the role of digital and remote technologies in learning and teaching during the ongoing COVID-19 pandemic. However, the research evidence on this topic is still fragmented, requiring a synthesis of this rapidly growing literature. This study aims to assess the key research trends in virtual learning during the COVID-19 pandemic through a bibliometric analysis of 1595 studies from 589 journals during 2020-21. Our study highlights the influential aspects, such as the most contributing countries, journals, authors, and keywords in this research field. We identified the following four main research trends: 1) challenges in online learning and blended learning strategies; 2) student-centered, collaborative learning, and curriculum design; 3) home-based laboratory learning; and 4) teachers' professional competence and interdisciplinary learning. We conclude this research by discussing the implications for regulators and educational institutions, and directions for future research.

    Cover papers of top journals are reliable source for emerging topics detection: a machine learning based prediction framework.
    Wenjie Wei, Hongxu Liu, Zhuanlan Sun.
      The detection of emerging trends is of great interest to many stakeholders such as government and industry. Previous research focused on the machine learning, network analysis and time series analysis based on the bibliometrics data and made a promising progress. However, these approaches inevitably have time delay problems. For the reason that leader papers of "emerging topics" share the similar characters with the "cover papers", this study present a novel approach to translate the "emerging topics" detection to "cover paper" prediction. By using "AdaBoost model" and topic model, we construct a machine learning framework to imitate the top journal (chief) editor's judgement to select cover paper from material science. The results of our prediction were validated by consulting with field experts. This approach was also suitable for the Nature, Science, and Cell journals.

    Visualization and Bibliometric Analysis of Carbon Neutrality Research for Global Health.
    Linghao Mao, Yiling Zhu, Chunhua Ju, Fuguang Bao, Chonghuan Xu.
      The visual analysis of carbon neutrality research can help better understand the development of the research field and explore the difficulties and hot spots in the research, thus making contributions to "carbon emission reduction," environmental protection and human health. This paper makes a visual quantitative analysis of 2,819 research papers published in top international journals from 2008 to 2021 in the WOS core database. It is found that China, the United States, Britain, and Germany are leading the way in carbon neutrality research. The research hotspots are mainly divided into three dimensions: (1) biomass energy and the negative effects it might bring; (2) ways and methods of electrochemical reduction of carbon dioxide; (3) catalysts and catalytic environment. The research mainly went through the conceptual period of 1997-2007, the exploration period of bioenergy from 2008 to 2021, the criticized period of bioenergy sources from 2011 to 2013, and the carbon dioxide electroreduction period from 2013 to the present. In the future, the research direction of biomass energy is to find one kind of biomass energy source which can be stored in a low-carbon way, produced in large quantities at a low cost, and will not occupy forestland. The electrolysis of water to produce hydrogen and the synthesis of fuel with CO2 are two major research directions at present, whose aims are to find the suitable catalyst and environment for the reaction. Besides, more research can be done on "carbon neutrality" policies so as to reduce carbon dioxide emissions from the source, develop a low-carbon economy and protect human health.

    Analysis of Scientometric Indicators in Publications Associated with Healthy Aging in the World, Period 2011-2020.
    Eric Rojas-Montesino, Diego Méndez, Yolanda Espinosa-Parrilla, Eduardo Fuentes, Iván Palomo.
      Today, the world population is aging at a fast rate. This scenario of the accelerated aging of human populations entails increased concern for healthy aging that is associated with a rise in scientific production related to the topic. In this study, the Scopus database from Elsevier was used, with a final search carried out on 5 January 2022, and various bibliometric indicators were obtained from SciVal. The study was fundamentally intended to characterize, determine trends, and understand the evolution and current state of research on the concept of "healthy aging" in the last decade. We found that there has been proportionally greater and more accelerated growth in the subject with respect to the general productivity of the world and that countries with high life expectancies tend to have made more effort to investigate this topic. The "hottest" research areas were found to be related to the cognitive aspect and the biological mechanisms involved in aging.

    Changing publication practices and the typification of the journal article in science and technology studies.
    Wolfgang Kaltenbrunner, Kean Birch, Thed van Leeuwen, Maria Amuchastegui.
      In this article, we study the development of the STS journal article format since the 1980s. Our analysis is based on quantitative data that suggest that the diversity of various journal publication types has diminished over the past four decades, while the format of research articles has become increasingly typified. We contextualize these historical shifts in qualitative terms, drawing on a set of 76 interviews with STS scholars and other stakeholders in scholarly publishing. Here, we first portray the STS publication culture of the 1980s and early 1990s. We then contrast this with an analysis of publishing practices today, which are characterized by a much more structured research process that is largely organized around the production of typified journal articles. Whereas earlier studies have often emphasized the importance of rhetorical persuasion strategies as drivers in the development of scholarly communication formats, our analysis highlights a complementary and historically novel set of shaping factors, namely, increasingly quantified research (self-)assessment practices in the context of a projectification of academic life. We argue that reliance on a highly structured publication format is a distinct strategy for making STS scholarship 'doable' in the sense of facilitating the planning ability and daily conduct of research across a variety of levels - including the writing process, collaboration with peers, attracting funding, and interaction with journals. We conclude by reflecting on the advantages and downsides of the typification of journal articles for STS.

    Towards a Fungal Science That Is Independent of Researchers' Gender.
    Nada Kraševec.
      The main drivers of gender mainstreaming in basic and clinical research appear to be funding agencies and scientific journals. Some funding agencies have already recognized the importance of their actions for the global development of ideas in science, but further targeted efforts are needed. The challenges for women scientists in fungal research appear to be similar to those in other science, technology, engineering, and mathematics disciplines, although the gender gap in mycology publishing appears to be less pronounced; however, women are underrepresented as last (corresponding) authors. Two examples of best practices to bridge the gap have been promoted in the fungal community: "power hour" and a central resource database for women researchers of fungi and oomycetes. A more balanced ratio of women researchers among (plenary) session speakers, (plenary) session chairs, and committee members at the recent fungal genetics conference is an encouraging sign that the gender gap can be closed. The editorial policy of some journals follows the guidance "Sex and Gender Equality in Research," and other journals should follow, and indicate the gender ratio among authors and reviewers.

    Patent bibliometric analysis for global trend of organoid technologies in the past decade.
    Lili Zhu, Yuhang Fan, Xuemei Huang, Tao Chen, Xiaodong Xu, Fang Xu, Yingying Gong, Pu Chen.
      Organoids are considered a game-changing paradigm of research models for human physiology and disease, which provides unsurpassed opportunities across disciplines in basic medical research, drug development, and personalized medicine. Here, we made a deep investigation for global patents of organoid technologies in the past decade using bibliometric analysis for the first time. We have identified a total of 672 patents related to organoid technology. The number of annual patent applications exhibits an overall upward growth trend over the past decade, especially entering an exponential growth since 2015. Notably, 76.64% of patents are related to the construction of organoid models. Liver, brain, and intestinal models take up the first three places in the physiological models, while tumor models account for 76.30% of the total patents for disease models. Furthermore, drug screening is the most preferred application, revealing the great commercial value of organoid technologies in precision medicine and preclinical drug screening.

    Review of Urban Flood Resilience: Insights from Scientometric and Systematic Analysis.
    Meiyan Gao, Zongmin Wang, Haibo Yang.
      In recent decades, climate change is exacerbating meteorological disasters around the world, causing more serious urban flood disaster losses. Many solutions in related research have been proposed to enhance urban adaptation to climate change, including urban flooding simulations, risk reduction and urban flood-resistance capacity. In this paper we provide a thorough review of urban flood-resilience using scientometric and systematic analysis. Using Cite Space and VOS viewer, we conducted a scientometric analysis to quantitively analyze related papers from the Web of Science Core Collection from 1999 to 2021 with urban flood resilience as the keyword. We systematically summarize the relationship of urban flood resilience, including co-citation analysis of keywords, authors, research institutions, countries, and research trends. The scientometric results show that four stages can be distinguished to indicate the evolution of different keywords in urban flood management from 1999, and urban flood resilience has become a research hotspot with a significant increase globally since 2015. The research methods and progress of urban flood resilience in these four related fields are systematically analyzed, including climate change, urban planning, urban system adaptation and urban flood-simulation models. Climate change has been of high interest in urban flood-resilience research. Urban planning and the adaptation of urban systems differ in terms of human involvement and local policies, while more dynamic factors need to be jointly described. Models are mostly evaluated with indicators, and comprehensive resilience studies based on traditional models are needed for multi-level and higher performance models. Consequently, more studies about urban flood resilience based on local policies and dynamics within global urban areas combined with fine simulation are needed in the future, improving the concept of resilience as applied to urban flood-risk-management and assessment.

    Defining a specialty through its literature: A bibliometric analysis of acute care surgery 2005 to 2020.
    John A Aucar, Jessica M Veatch, Elizabeth Kiscaden.
      Background: Acute care surgery (ACS) has grown and evolved since it was conceived in 2005. However, ACS is not recognized in the National Library of Medicine's Medical Subject Heading thesaurus. This article uses bibliometrics to help define an identity for ACS as a subspecialty of surgery and argue for its addition to the Medical Subject Heading thesaurus.Methods: The terms "Acute Care Surgery," "Wounds and Injuries," "General Surgery," and "Critical Care" were searched with and without the Text Word [TW] modifier using PubMed. The intersections of search sets were identified with the AND conjunction to determine the proportion of ACS literature relevant to each subject term and calculate the penetration of ACS as a keyword term into each subject domain.
    Results: A [Medical Subject Heading] limited search on the term "Acute Care Surgery" yielded a predictable return of 0 article. Search of the cohesive term "Acute Care Surgery" [All Fields], restricted to MEDLINE-indexed, English-language articles yielded 2,351 articles published between 2005 and 2020, inclusive. Using ACS as [Text Word] yielded 517 articles. There was a progressive increase in the rate of annual publications. The frequency of subject terms in the ACS [All Fields] set was as follows: Critical Care, 49.70%; General Surgery, 23.26%; and Wounds and Injuries, 20.88%. The frequency of subject terms in the ACS [TW] set was as follows: Critical Care, 32.88%; General Surgery, 43.52%; and Wounds and Injuries, 15.28%. Of this set, 8.32% of articles were not tagged or did not contain a reference to any of these 3 major subjects.
    Conclusion: This study demonstrates that ACS as a subject matter is being increasingly expressed in the literature. Adding ACS as a dedicated term into the National Library of Medicine's Medical Subject Heading thesaurus of controlled vocabulary as a specialty of Surgery would facilitate indexing and retrieval of the literature most relevant to acute care surgeons.

    Research Trends in Crop-Livestock Systems: A Bibliometric Review.
    Guoting Yang, Jing Li, Zhen Liu, Yitao Zhang, Xiangbo Xu, Hong Zhang, Yan Xu.
      Agricultural straw waste and livestock manure are often misplaced resources. The separation of planting and breeding has induced significant pressure on the environment. Thus, there is a growing need for a system that can integrate crop and livestock farming to improve resource efficiency. To clarify the current state of crop-livestock systems in China and elsewhere, a bibliometric analysis was conducted for a total of 18,628 published English and 3460 published Chinese research articles and dissertations on circular agriculture. The published research papers were taken from the ISI Web of Science and CNKI database to explore research hotpots, research methods, theme trends, and mainstream technical models of crop-livestock systems from 1981 to 2021. Recent progress in crop-livestock systems was analyzed from ecological, economic, social benefits, and stakeholder perspectives. The research results showed that compared with traditional agricultural models, crop-livestock systems had far more ecologic and social benefits, including gaining higher net income and input-output ratio, improving soil quality, and mitigating global warming. The drivers of crop-livestock systems' development were also analyzed from stakeholders' perspectives. The study provides insights into the development of circular agriculture by reducing the pollution risks of agricultural waste and improving both ecological and economic benefits of the system.

    Golf and Health, More than 18 Holes-A Bibliometric Analysis.
    María Del Mar Martín-García, José Luis Ruiz-Real, Juan Carlos Gázquez-Abad, Juan Uribe-Toril.
      Despite golf's contribution to health, scientific production related to golf and health has been relatively scarce. This work aims to investigate the state of the art on golf and health and to identify existing gaps and the principal and most notable potential future research trends, contributing to connecting the reality of the facilities dedicated to the practice of this sport and its contribution to raising awareness of the importance of sport in maintaining health. A total of 179 articles were analyzed following the steps for systematic reviews and meta-analysis protocols based on the PRISMA 2020 methodology and QUORUM, and a bibliometric analysis was carried out. Research to date has mainly focused on the benefits of golf in improving health, preventing illness, slowing down aging, or as rehabilitation and on exploring the risks and injuries involved in playing golf. The different ways of promoting participation or changing the image of golf by showing its healthy side are outlined as research trends in the coming years. There is a lack of exploration of the use of technology, the effects of the sport on certain disorders related to psychosocial factors, and further knowledge of the relationships between playing intentions and health. This research provides essential information for researchers who plan to work with golf in the future.

    Publication Bias in Urology Systematic Reviews and Meta-Analyses.
    Amirmahdi Khayyamfar, Sepehr Khosravi, Robab Maghsoudi, Behnam Shakiba.
      Background Publication bias is one of the most important biases in systematic reviews and meta-analyses. This bias occurs when the results of an article affect its publication, in other words positive or significant findings are more likely to be published than the other probable results. Previous studies have shown that publication bias has been a matter of concern in the meta-analysis and systematic reviews conducted in some medical fields.  There is not a study that has evaluated the status of publication bias assessment in urology systematic reviews. We decided to assess the status of publication bias evaluation in systematic reviews and meta-analyses published in high impact urology journals.   Methods This cross-sectional study was performed on 200 systematic reviews and meta-analysis published in four top urology journals based on their impact factor (European Urology, The Journal of Urology, BJU International and Prostate Cancer and Prostatic Diseases). Two independent reviewers performed data extraction about publication bias evaluation in included systematic reviews.   Results From the 200 included studies only 65 (32.5%) evaluated the publication bias in the review process and 31 reviews had reported publication bias in their study. Visual inspection of a funnel plot was the most frequent method used for evaluation of publication bias (61 from 65, 93.85%); this method was used alone in 34 articles and in combination with other methods in 27 papers.   Conclusion The present study confirms that publication bias was formally evaluated in a small number of reviews and meta-analysis published in urology journals, therefore, this may be a risk factor that could decrease the robustness of outcomes and results of these studies. It seems that there is an essential need for authors, reviewers, and editors to pay better attention to evaluation of publication bias besides reporting it based on the aforementioned reporting guidelines.

    The evolution of leadership: analyzing the presidents of American Dermatology Societies overtime.
    Yasmine Abushukur, Meghan Mansour, Camilla Cascardo, Jacob Keeley, Thomas Knackstedt.
      Within organized dermatology, it is imperative that leaders embody a diverse group of individuals, reflective of the dermatologists they represent and the greater U.S. population. Despite women constituting more than half of the dermatologic workforce, they represent a leadership minority in dermatology society higher level positions. This gap is evident by fewer women holding presidency positions within prominent dermatological societies; however, a comprehensive comparison across multiple societies has yet to be made. Our study analyzes and compares demographic as well as academic metrics of presidents from 16 prominent dermatology societies spanning 22 years, 2000-2021. Data were collected using organization websites, which demonstrated 247 unique presidents over 22 years. Of these presidents, 175 (70.9%) were male and 72 (29.1%) were female. Surgically focused societies had 63 (87.5%) male presidents and nine (12.5%) female presidents, while clinically focused societies had 112 (64.0%) male presidents and 63 (36.0%) female presidents (P < 0.0002). The publication h-index, academic rank, chairmanship, and number of advanced degrees, and total number of years in practice prior to election did not significantly differ between male and female leaders. There was no statistically significant difference in the proportion of female presidents across all societies between 2000 and 2021 by Cochran Armitage Trend Test. However, between 2016 and 2021, 35% of presidents were female and a general trend toward more gender balance may be noticed. This equality goal should continue to be emphasized in organized medicine.

    Institution Publication Feature Analysis Based on Time-Series Clustering.
    Weibin Lin, Mengwen Jin, Feng Ou, Zhengwei Wang, Xiaoji Wan, Hailin Li.
      Based on the time series of articles obtained from the literature, we propose three analysis methods to deeply examine the characteristics of these articles. This method can be used to analyze the construction and development of various disciplines in institutions, and to explore the features of the publications in important periodicals in the disciplines. By defining the concepts and methods relevant to research and discipline innovation, we propose three methods for analyzing the characteristics of agency publications: numerical distribution, trend, and correlation network analyses. The time series of the issuance of articles in 30 important journals in the field of management sciences were taken, and the new analysis methods were used to discover some valuable results. The results showed that by using the proposed methods to analyze the characteristics of institution publications, not only did we find similar levels of discipline development or similar trends in institutions, achieving a more reasonable division of the academic levels, but we also determined the preferences of the journals selected by the institutions, which provides a reference for subject construction and development.

    Endocrine research in Bangladesh: Evolution and current trend.
    A B M Kamrul-Hasan, Shahjada Selim.
      Background: The contribution of Bangladesh to global endocrine research is not quantified. We intend to summarize the progress Bangladesh has made in endocrine research.Methods: Global and country-specific data up to December 2021 from the PubMed database were retrieved using the keywords 'diabetes mellitus', 'obesity', 'thyroid', 'adrenal' and 'pituitary'; the keywords 'gonad' OR 'hypogonadism' OR 'PCOS' OR 'sexual dysfunction' were used for retrieving data of reproductive endocrinology research; and 'bone metabolism' OR 'osteoporosis' OR 'vitamin D' were used for bone metabolism research. Bangladeshi contributions to endocrine research were compared to global and country-specific data during the periods '1972-2021' and '2012-2021'.
    Results: Bangladesh has 2,467 articles in the PubMed database in different fields of endocrinology during the period 1972-2021, which is 0.132% of the total global endocrine publications published in this timeframe. We observed a gradual increment in the number of Bangladeshi publications over the last five decades in all fields of endocrinology. Over the last 10 years, the contribution has risen to 0.226% with 2003 publications.
    Conclusions: Currently, Bangladesh contributes very little to global endocrine research. An urgent call to amplify research works by Bangladeshi endocrinologists is of utmost importance to catch up with the global publications in endocrinology.

    A Review of Ecosystem Services Research Focusing on China against the Background of Urbanization.
    Qindong Fan, Xiaoyu Yang, Chenming Zhang.
      The change in landscape patterns caused by urbanization is one of the main reasons for the degradation of global ecosystem services. Reducing the negative impact of rapid urbanization on ecosystems and promoting the coordinated development of cities and ecosystems have become a hot topic around the world. Based on Web of Science Core Collection and CNKI database papers, this study conducts a bibliometric analysis of ecosystem services research against the background of global urbanization from 2000 to 2022. At the same time, the research hot spots, regional distribution, research trends, and research contents are summarized by taking China as the key research area. The results show that: (1) the research hot spots of ecosystem services against the background of urbanization are generally the same in China and the world. Both of them are based on landscape pattern or land use; the research scale is from macro to micro; and the research method is from static to dynamic. (2) From the perspective of ecosystem service types, the four types of ecosystem service have been studied in China and other parts of the world, but there are differences in the specific types, quantity, and regional distribution. (3) Whether in China or other regions of the world, the studies on the trade-offs of ecosystem services against the background of urbanization are mainly at medium and large scales. Finally, ecosystem service bundles research, systematic thinking, and the combination of ecosystem services and territorial spatial planning against the background of urbanization are pointed out as key aspects of future research.

    Neurotoxicity of Polycyclic Aromatic Hydrocarbons: A Systematic Mapping and Review of Neuropathological Mechanisms.
    Tosin A Olasehinde, Ademola O Olaniran.
      Several studies present the neurotoxic effects of polycyclic aromatic hydrocarbons (PAHs), a class of environmental pollutants capable of causing neurological deficits. However, a collective review approach to this research topic is scarce. This study presents the effect of PAHs on the central nervous system using a bibliometric approach. The neuropathological mechanisms of PAHs are also highlighted. Published articles were searched for in the Scopus and Web of Science databases from January 1979 to December 2020 using the keywords 'polycyclic aromatic hydrocarbons' and 'neurotoxicity'. The total number of documents retrieved from both databases was 338. Duplicated documents (80) were excluded and 258 articles were used for the final analysis. Our findings revealed that there has been a significant increase in research outputs on this topic in the last ten years. The countries with the highest scientific productivity in this area are USA, China, France and Italy. The result also showed that, in the past few years, global scientific output in research relating to PAH neurotoxicity focused on neurodegeneration, cholinergic function, neurodevelopmental toxicity, behavioural studies, oxidative stress, neuroprotection and therapeutic intervention using different experimental models, including zebrafish, neuronal cell lines, Caenorhabditis elegans and rats. Recent studies also revealed the neuroprotective roles of some natural products against PAH-induced neurotoxicity. However, more investigation involving clinical trials is required to emphasize the observed neurotoxic effects.

    Ángel Acevedo-Duque, Gonzalo R Llanos-Herrera, Elizabeth Emperatriz García-Salirrosas, Selene Simón-Isidoro, Agustín Pablo Álvarez-Herranz, Rina Álvarez-Becerra, Lisette C Sánchez Díaz.
      Hiking is a sports activity that takes place in the natural environment. From the point of view of well-being, it is an aerobic activity that prevents and improves cardiovascular diseases. According to data provided by the United Nations, within the framework of the International Year of Mountains, mountain tourism represents around 15% to 20% of total world tourism revenue. This approach aims to critically analyze the scientific production on trail tourism (HT) with contributions from authors from around the world from 1991 to 2022, in order to respond to the connection between this research, knowledge management and the sustainable development of the industry. Key knowledge contributions are examined using a scientometric approach as a method (spatial, production, impact, and relational) based on registry data stored in the Web of Science (JCR and ESCI). Regarding the results, there has been an increase in scientific production in the last decade, which is manifested in the quality of the publications.

    Digital Health in Children's Oral and Dental Health: An Overview and a Bibliometric Analysis.
    Peivand Bastani, Nithin Manchery, Mahnaz Samadbeik, Diep Hong Ha, Loc Giang Do.
      Digital health technologies can widely increase access to oral health solutions and can make them easier to use and more accessible at all primary, secondary, and tertiary levels. This study aims to present a bibliometric analysis of published literature to identify the content, trends, and context of digital health technology use in children's oral and dental health. After finalising the research question, the Scopus database was used to search systematically for related keywords from 1997 to 2022. The PRISMA methodology applied for systematic reviews was adopted to refine search results. VOS viewer software was applied to illustrate the topics and trends of digital health technology involved in children's oral and dental health. An increase in use of the digital technologies was appeared in the index keywords after 2005. Computer-assisted therapy/surgery, computer simulation, computer program, image processing, nuclear magnetic resonance (NMR) imaging, and audio-visual equipment were more used index keywords in children's dental care re-search from 2005-2015. Telemedicine, mobile application, virtual reality, and medical information were reported with the index keywords of dental caries, dental procedures, and dental anxiety after 2015. The study also identified a gap in the published literature in applying newer digital technologies, such as the Internet of Things (IoT) and gamification, in oral and dental health research and practice. There is a growing tendency to use digital technologies in children's oral and dental health in recent years. Although the types and categorisations of the technology are typically diverse during the timeframe and by the area of dental services and oral health, identifying and categorizing these technologies based on oral health services could familiarise oral health policymakers with the application of the technology and help them design technology-based interventions to improve children's oral health.

    Hormesis Research in China Is More Prevalent than Previously Thought.
    Evgenios Agathokleous, Caiyu Geng, Boya Zhou, Haoyu Sun, Jiahua Guo, Jing Zhang, Fuxing Zhu.
      An analysis of China's domestic publications revealed that China's hormesis-related research was enormously underestimated. China's documented hormesis-related research spans at least four decades, covers a broad spectrum of research areas, and is more abundant than previously thought. These findings should be considered in historical assessments of the concept of hormesis. Moreover, similar to the international literature, different terms have been used to describe the same phenomenon (hormesis), which hampers communication, generalization of findings and accumulation of knowledge. Hence, we advocate that 'hormesis' should be cited as a keyword in all the relevant publications written in Chinese language.

    The evolution and co-evolution of a primary care cancer research network: From academic social connection to research collaboration.
    Debbie Vermond, Esther de Groot, Valerie A Sills, Georgios Lyratzopoulos, Fiona M Walter, Niek J de Wit, Greg Rubin.
      Academic networks are expected to enhance scientific collaboration and thereby increase research outputs. However, little is known about whether and how the initial steps of getting to know other researchers translates into effective collaborations. In this paper, we investigate the evolution and co-evolution of an academic social network and a collaborative research network (using co-authorship as a proxy measure of the latter), and simultaneously examine the effect of individual researcher characteristics (e.g. gender, seniority or workplace) on their evolving relationships. We used longitudinal data from an international network in primary care cancer research: the CanTest Collaborative (CanTest). Surveys were distributed amongst CanTest researchers to map who knows who (the 'academic social network'). Co-authorship relations were derived from Scopus (the 'collaborative network'). Stochastic actor-oriented models were employed to investigate the evolution and co-evolution of both networks. Visualizing the development of the CanTest network revealed that researchers within CanTest get to know each other quickly and also start collaborating over time (evolution of the academic social network and collaborative network respectively). Results point to a stable and solid academic social network that is particularly encouraging towards more junior researchers; yet differing for male and female researchers (the effect of individual researcher characteristics). Moreover, although the academic social network and the research collaborations do not grow at the same pace, the benefit of creating academic social relationships to stimulate effective research collaboration is clearly demonstrated (co-evolution of both networks).

    Scholarly Activity and Research Training in Urology Residency Programs: Assessment of Current Practice and Barriers.
    Lauren S Faber, Martin Jurado, Renata Bennett-Perez, Frances M Alba.
      OBJECTIVES: To identify factors associated with effective scholarly activity and identify barriers to research during urology residency.METHODS: An online survey was sent to 134 urology residency program directors in the United States. The survey assessed program characteristics, available support, and barriers for scholarly activity. Logistic regression analysis was used to identify characteristics of programs in the top quintile for success in scholarly activity.
    RESULTS: There was a 40% response rate (n=40). The majority of programs (86%) were university affiliated. Nearly all programs (98%) require participation in scholarly activity as a requirement for graduation. There were three primary outcomes evaluated: participation in original research, published scholarly activity and presentation of scholarly activity. Factors significantly associated with participation in original research were required research time (p=0.06), lack of experienced faculty (p=0.006), statistical and IRB support (p=0.03, p=0.01), funding (p=0.02), and research curriculum (p=0.006). Factors significantly associated with publication in peer reviewed journals were lack of funding and experienced faculty (p=0.07, p=0.01). Factors significantly associated with presentation of scholarly activity included research director (p=0.05), chairman support (p=0.02), research training (p=0.03), protected time for faculty (p=0.07), and faculty /resident attitudes toward conducting scholarly activity (p=0.08, p=0.02) and resident promotion linked to scholarly activity (p=0.01).
    CONCLUSIONS: Training urology residents in research is essential. Current methods and available resources are variable. Programs should identify resources and barriers that have the greatest impact on resident success in scholarly activity, and may implement changes to improve productivity within their program.

    A Systematic Review and Bibliometric Analysis of Flame-Retardant Rigid Polyurethane Foam from 1963 to 2021.
    Ying Pan, Chengliang Yin, Carlos Fernandez, Li Fu, Cheng-Te Lin.
      Flame-retardant science and technology are sciences developed to prevent the occurrence of fire, meet the needs of social safety production, and protect people's lives and property. Rigid polyurethane (PU) is a polymer formed by the additional polymerization reaction of a molecule with two or more isocyanate functional groups with a polyol containing two or more reactive hydroxyl groups under a suitable catalyst and in an appropriate ratio. Rigid polyurethane foam (RPUF) is a foam-like material with a large contact area with oxygen when burning, resulting in rapid combustion. At the same time, RPUF produces a lot of toxic gases when burning and endangers human health. Improving the flame-retardant properties of RPUF is an important theme in flame-retardant science and technology. This review discusses the development of flame-retardant RPUF through the lens of bibliometrics. A total of 194 articles are analyzed, spanning from 1963 to 2021. We describe the development and focus of this theme at different stages. The various directions of this theme are discussed through keyword co-occurrence and clustering analysis. Finally, we provide reasonable perspectives about the future research direction of this theme based on the bibliometric results.

    Pigeon Circovirus over Three Decades of Research: Bibliometrics, Scoping Review, and Perspectives.
    Benji Brayan Ilagan Silva, Michael Louie R Urzo, Jaymee R Encabo, Alea Maurice Simbulan, Allen Jerard D Lunaria, Susan A Sedano, Keng-Chih Hsu, Chia-Chi Chen, Yu-Chang Tyan, Kuo-Pin Chuang.
      The pigeon circovirus (PiCV), first described in the literature in the early 1990s, is considered one of the most important infectious agents affecting pigeon health. Thirty years after its discovery, the current review has employed bibliometric strategies to map the entire accessible PiCV-related research corpus with the aim of understanding its present research landscape, particularly in consideration of its historical context. Subsequently, developments, current knowledge, and important updates were provided. Additionally, this review also provides a textual analysis examining the relationship between PiCV and the young pigeon disease syndrome (YPDS), as described and propagated in the literature. Our examination revealed that usages of the term 'YPDS' in the literature are characterizations that are diverse in range, and neither standard nor equivalent. Guided by our understanding of the PiCV research corpus, a conceptualization of PiCV diseases was also presented in this review. Proposed definitions and diagnostic criteria for PiCV subclinical infection (PiCV-SI) and PiCV systemic disease (PiCV-SD) were also provided. Lastly, knowledge gaps and open research questions relevant to future PiCV-related studies were identified and discussed.
