    Current Trends and Research Hotspots in Pancreatic Stellate Cells: A Bibliometric Study.
    Zhaoming Yang, Zhiqin Xie, Jian Wan, Bo Yi, Tao Xu, Xiaorong Shu, Zhijian Zhao, Caixi Tang.
       Background: Pancreatic stellate cells (PSCs) play crucial roles in acute/chronic pancreatitis and pancreatic cancer. In this study, bibliometric analysis was used to quantitatively and qualitatively analyze the literature related to PSCs from 1998-2021 to summarize the current trends and research topics in this field.
    Methods: Relevant literature data were downloaded from the Science Citation Index Expanded Web of Science Core Collection (WoSCC) on April 07, 2021, using Clarivate Analytics. Biblioshiny R packages, VOSviewer, Citespace, BICOMB, gCLUTO, and the Online Analysis Platform of Literature Metrology (http://bibliometric.com) were used to analyze the manually selected data.
    Results: A total of 958 relevant studies published in 48 countries or regions were identified. The United States of America (USA) had the highest number of publications, followed by the People's Republic of China, Germany, and Japan. Tohoku University (Japan), the University of New South Wales (Australia), the University of Texas MD Anderson Cancer Center (USA), Technical University of Munich (Germany), and University of Rostock (Germany) were the top five institutions with most publications. Nine major clusters were generated using reference co-citation analysis. Keyword burst detection revealed that progression (2016-2021), microenvironment (2016-2021), and tumor microenvironment (2017-2021) were the current frontier keywords. Biclustering analysis identified five research hotspots in the field of PSCs during 1998-2021.
    Conclusion: In this study, a scientometric analysis of 958 original documents related to PSCs showed that the research topics of these studies are likely in the transition from acute/chronic pancreatitis to pancreatic cancer. The current research trends regarding PSCs are related to pancreatic cancer, such as tumor microenvironment. This study summarizes five research hotspots in the field of PSCs between 1998 and 2021 and thus may provide insights for future research.

    A Bibliometric Analysis of the Innate Immune DNA Sensing cGAS-STING Pathway from 2013 to 2021.
    Xuan Shi, Sheng Wang, Yutong Wu, Quanfu Li, Tong Zhang, Keting Min, Di Feng, Meiyun Liu, Juan Wei, Lina Zhu, Wei Mo, Zhuoran Xiao, Hao Yang, Yuanli Chen, Xin Lv.
       Background and aims: Cyclic guanosine monophosphate (GMP)-adenosine monophosphate (AMP) (cGAMP) synthase (cGAS) and stimulator of interferon genes (STING) are key components of the innate immune system. This study aims to evaluate the research of cGAS-STING pathway and predict the hotspots and developing trends in this field using bibliometric analysis.
    Methods: We retrieved publications from Science Citation Index Expanded (SCI-expanded) of Web of Science Core Collection (WoSCC) in 1975-2021 on 16 March 2022. We examined the retrieved data by bibliometrix package in R software, VOSviewer and CiteSpace were used for visualizing the trends and hotspots of research on the cGAS-STING pathway.
    Results: We identified 1047 original articles and reviews on the cGAS-STING pathway published between 1975 and 2021. Before 2016, the publication trend was increasing steadily, but there was a significant increase after 2016. The United States of America (USA) produced the highest number of papers (Np) and took the highest number of citations (Nc), followed by China and Germany. The University of Texas System and Frontiers in Immunology were the most prolific affiliation and journal respectively. In addition, collaboration network analysis showed that there were tight collaborations among the USA, China and some European countries, so the top 10 affiliations were all from these countries and regions. The paper published by Sun LJ in 2013 reached the highest local citation score (LCS). Keywords co-occurrence and co-citation cluster analysis revealed that inflammation, senescence, and tumor were popular terms related to the cGAS-STING pathway recently. Keywords burst detection suggested that STING-dependent innate immunity and NF-κB-dependent broad antiviral response were newly-emerged hotspots in this area.
    Conclusions: This bibliometric analysis shows that publications related to the cGAS-STING pathway tend to increase continuously. The research focus has shifted from the mechanism how cGAS senses dsDNA and cGAMP binds to STING to the roles of the cGAS-STING pathway in different pathological state.

    A Bibliometric Analysis of 100 Most-Cited Articles on Corneal Cross-Linking.
    Kaili Yang, Liyan Xu, Shaopei Wang, Meng Zhu, Qi Fan, Yuwei Gu, Yawen Wang, Qing Wang, Dongqing Zhao, Chenjiu Pang, Shengwei Ren.
       Background: Highly cited papers are expected to have high-quality data that significantly contribute to the body of knowledge. The study aimed to evaluate the characters of the 100 most-cited articles on corneal cross-linking (CXL) through a bibliometric analysis.
    Materials and Methods: The Web of Science database was searched to identify papers published from 1950 to 2020. A bibliometric analysis of the top 100-cited articles was conducted in the current study. The citation differences between basic research, clinical research, and reviews were compared by Kruskal-Wallis test. The association between citations and publication year was evaluated by Spearman correlation analysis. The VOSviewer software was used to create networks of co-authorship and keywords map.
    Results: The median values of the number of citations, citations/year since publication, and citations since 2013 were 101, 9.5, and 11.92, respectively. A total of 61% of articles were clinical research. The citations since 2013 of clinical research were lower than basic research and the reviews (all p < 0.001). The publication year was positively correlated with the number of publications (r = 0.665, p = 0.013), and the total number of citations decreased for basic research (r = -0.447, p = 0.017), and clinical research (r = -0.433, p < 0.001). The J REFRACT SURG publishes the highest number of articles. The corresponding authors were predominantly from the Italy (N = 17), Germany (N = 16), and United States (N = 15). Spoerl Eberhard has the highest number of citations and total link strength with 15 articles. Extensive collaboration existed among the main core nodes containing "cross-linking (N = 45)," "riboflavin (N = 44)," and "ultraviolet A (UVA) (N = 42)."
    Conclusion: The present study focused on the comprehensive analysis of the top 100-cited articles on the CXL research, providing insight into research developments over the past decades.

    Global and Chinese publications in plastic surgery journals between 2010 and 2020: a bibliometric analysis.
    Han Zeng, Xiaolei Jin, Chenzhi Lai.
       Background: Plastic surgery has evolved rapidly in recent years. We performed a bibliometric analysis of plastic surgery publications from 2010 to 2020 to evaluate global developments in plastic surgery and the Chinese contribution to this field.
    Methods: The 2020 Journal Citation Reports (JCR) was used to identify all plastic surgery journals; those that were available on the Web of Science database were retrieved and analyzed according to their number of published articles, citation rates, impact factors (IFs), research funding, and article references. We also determined the most popular journals for research from the 8 top-ranking countries in terms of contributed articles, including China.
    Results: From 2010 to 2020, 55,554 articles were published in the 35 selected plastic surgery journals. China, which contributed 9.48% of these articles, was the country with the second-highest number of articles published, a number which has been increasing annually. The average IF of Chinese articles was 1.74, with an average citation count of 6.68. These figures were significantly lower than those for articles from developed countries. China contributed 1,641 articles to the 10 highest impact plastic surgery journals. The Journal of Craniofacial Surgery was the most popular in terms of contributions by China. China had the highest rate of articles supported by funding (45.30%). The top 12 research-topic clusters were obtained by analyzing the references in the articles. Emerging research-topic trends worldwide and in China included fat grafting and blindness after filler injection.
    Conclusions: From 2010 to 2020, research into plastic surgery increased continuously, both worldwide and in China. However, the quality of the Chinese articles was lower than that of other top-ranked countries. Researchers who have elected to conduct research might consider emerging trends when designing future studies.

    Global trends in anesthetic research over the past decade: a bibliometric analysis.
    Manhai Gao, Weirong Liu, Zhiqiang Chen, Wei Wei, Yanlong Bao, Qiang Cai.
       Background: Anesthesia is the reversible inhibition of function of the central and/or peripheral nervous system using drugs or other means to ensure a successful operation. This inhibition is mainly manifested as a loss of sensation, especially pain.
    Methods: Bibliometric analysis was used to identify the characteristics, hotspots, and frontiers of global anesthesiology scientific output during the past 10 years. Literatures between 2011 and 2020 in the Web of Science Core Collection (WoSCC) were reviewed and analyzed. VOSviewer was used to visualize trends and hotspots in anesthesia research.
    Results: A total of 16,213 publications were retrieved and results showed that there was no significant correlation between the number of articles published each year and the year of publication. England had the most published papers, the greatest number of citations (NC), and the highest h-index. The University of London and the British Journal of Anesthesia were the richest affiliate and journal, respectively. The publication written by Heidenreich et al. had the highest global citation score (GCS).
    Conclusions: Our research found that global publications on anesthesia have raised. Recently, "surgery", "management", "propofol", and "analgesia" appeared most frequently, which were active areas of research. In the future research, pain management, pediatric anesthesia, safety, dexmedetomidine, et al. will be the hotspot and mainstream trend of research.

    Publications in Pediatric Epilepsy: Using Bibliometrics to Determine Readings in the Field.
    Andrew J Gienapp, Wiley Pippenger, Amy L McGregor, Stephen P Fulton.
      Bibliometrics and citation analysis are popular forms of analyzing medical literature based on article impact as determined by the number of citations an article has received from other publications. Many bibliometric studies published within the past 10 years have assembled lists of highly cited papers, top 100 papers, or citation classics of specialties, subspecialties, and specific morbidities. For pediatric epilepsy, there is only 1 study that bibliometrically examines articles in this subspecialty. Although bibliometrics generally examines trends in the literature, we used bibliometrics as a methodology for determining a core set of pediatric epilepsy articles with the highest impact (ie, citation count) that could be used as an introductory reading list for residents, fellows, and early career epileptologists. Therefore, we searched Web of Science to identify the 100 top-cited pediatric epilepsy articles and develop 10 topic areas into which we sorted each article. These recommended articles could be used as essential readings for pediatric epilepsy.

    Fabriccio J Visconti-Lopez, Dustin M Solorzano-Salazar, Rodrigo Vargas-Fernández.
       OBJECTIVES: Determine the bibliometric characteristics of scientific articles that address the subject of neurosurgery in Latin America and the Caribbean (LAC).
    METHODS: A bibliographic search of original articles published in the Web of Science database up to 2021 was performed, without language restrictions. The terms included in the search strategy were Neurosurgery, neurosurgical procedures and neurological surgical procedure. Articles according to the inclusion criteria in the Rayyan application were included. Subsequently, a quantitative bibliometric analysis was carried out with the bibliometrix package in R and VOSviewer.
    RESULTS: 882 articles published in 271 journals were identified. The first publication was in 2006, the highest number of publications was in 2021, the annual percentage growth rate was 25.9 and the average number of citations per document was 11.2. The author with the highest number of publications was TEIXEIRA MJ (41 articles) and the University of Sao Paulo had the highest number of articles on this topic. World neurosurgery was the journal with the most publications (120 articles) and the study by CARNEY N (2017) was the most cited (1175 citations). The country of the corresponding authors with the most publications and the greatest number of total citations was Brazil. NEUROSURGERY, SURGERY and MANAGEMENT were the most used keywords; however, in the most recent articles SIMULATION and DEEP BRAIN STIMULATION were used.
    CONCLUSIONS: In the last decade, there has been an increase in articles on Neurosurgery in LAC. Scientific production in neurosurgery must continue to increase in order to promote evidence-based medicine.

    Examination of the most cited studies on transcatheter aortic valve replacement with bibliometric analysis.
    Tuncay Güzel, Bayram Arslan.
       AIM: The aim of this study is to analyze the studies on TAVI with the bibliometric method and to perform a scientiometric analysis of the top 100 most cited articles for researchers.
    METHODS: The Thomson Reuters Web of Science database was searched for all relevant articles using the terms "TAVR" and "TAVI". The results were ordered according to the number of citations. We also analyzed the 100 most cited articles (T100) by annual average citation count (ACpY), years, research methods, author, institution, journal, funding agencies, and keywords. Analyses were also performed between the total number of citations, ACpY, impact factors, and publication time.
    RESULTS: The article titled "Transcatheter Aortic-Valve Implantation for Aortic Stenosis in Patients Who Cannot Undergo Surgery" was the most cited article (n = 4616). The article titled "Transcatheter Aortic-Valve Replacement with a Balloon-Expandable Valve in Low-Risk Patients" had the highest ACpY count (n = 497). The United States was the country that contributed the most to the T100 list. While the journal that contributed the most with 32 articles was "Journal of the American College Of Cardiology", the journal in which the top 10 most cited articles were published most frequently was the "New England Journal of Medicine". In addition, the most publications were made in 2012.
    CONCLUSION: Although this bibliometric analysis study has some limitations, it allows the most cited publications on TAVI to be analyzed systematically and provides scientific contributions.

    Taimoor Hussain, Andre Corraes, Khalida Walizada, Rajeswari Khan, Jafrikh Thamara Kunnath, Tuba Khan, Asjad Salman Zahid, Zahra Mushtaq, Mohit Bhagia, Vishnu R Bhure.
      Dementia is a syndrome of cognitive impairment that affects an individual's ability to live independently. The number of people living with dementia worldwide in 2015 was estimated at 47.47 million. The American Academy of Neurology (AAN) criteria for human immunodeficiency virus (HIV)-associated dementia (HAD) require an acquired abnormality in at least two cognitive (non-motor) domains and either an abnormality in motor function or specified neuropsychiatric/psychosocial domains. HIV is the most common cause of dementia below 60 years of age. Citation frequencies are commonly used to assess the scholarly impact of any scientific publication in bibliometric analyses. It helps depict areas of higher interest in terms of research frequency and trends of citations in the published literature and identify under-explored domains of any field, providing useful insight and guidance for future research avenues. We used the database "Web of Science" (WOS) to search for the top 100 cited articles on HIV-associated dementia. The keywords "HIV dementia" and "HIV-associated neurocognitive disorders" (HAND) were used. The list was generated by two authors after excluding articles not pertaining to HIV dementia. The articles were then assigned to authors to extract data to make tables and graphical representations. Finally, the manuscript was organized and written describing the findings of the bibliometric study. These 100 most cited articles on HIV dementia were published between years 1986 and 2016. The highest number of the articles was from 1999 (n=9). The year 1993-2007 contributed consistently two publications to the list. The articles are from 42 journals, and among them, the Annals of Neurology (n=16) and the Journal of Neurology (n=15) published most of the articles. Justin C. McArthur with 25 publications contributed the highest number of papers to the list by any author. The USA collaborated in the highest number of publications (n=87). American institutes were leading the list with the most publications. The Johns Hopkins University collaborated on 37 papers. The most widely studied aspect of HIV dementia was pathogenesis. Incidence and prevalence, clinical features, and pre- and post-highly active antiretroviral therapy (HAART) era were also discussed in the articles. Beyond America, the research should be expanded to low-income countries and those affected more by HIV. Therefore, other countries and their institutes should participate more in HIV-associated dementia research. Anticipating the rising resistance to existing antiretrovirals, we should develop new therapeutic options. There is room for research in many aspects of HIV dementia care.

      We conducted a bibliometric analysis to identify scholarly impact and factors associated with the top 100 cited articles on clinical hematopoietic stem cell transplantation (HSCT). In January 2021, a title-specific search was conducted. Non-HSCT and pre-clinical (in-vitro and animal) studies were excluded. A total of 39,406 records were identified and a list of the top 100 articles was made. Articles included in our study were characterized by the citations received, publication year, topic, study design, authors, h-index, and institutions. Linear regression analyses were performed. The 100 most cited articles were published over 52 years from 1968 to 2020, with a maximum number of articles (n = 40) published in the 1990s decade. Top-100 articles were cited 62,002 times with a median citation count of 465 (range 336-2240). The top-cited articles originated from 12 countries. United States contributed 69 articles. The University of Washington Fred Hutchinson Cancer Center (n = 15) was the leading institution. Blood (n = 32) and New England Journal of Medicine (n = 31) made the greatest contribution, and 52 manuscripts were clinical trials. The first author's H-index significantly correlated with citation count while journal impact factor, years since publication, first author's gender, and the number of authors did not have a significant association with the number of citations. In a multivariate regression model, the first author's h-index (regression coefficient 5.46, 95% confidence interval 2.99 to 7.93, p < 0.001) independently correlated with the citation count. Our study highlights the most influential articles on clinical HSCT and provides valuable insight for future research needs of the specialty.

    Research Trends on Pulmonary Rehabilitation: A Bibliometric Analysis From 2011 to 2020.
    Tao Li, Jia Chen.
       Background and Objective: A mounting body of evidence suggests that lung function may deteriorate over time with the development of chronic lung diseases (CRDs). Pulmonary rehabilitation has been proved to improve exercise capacity and quality of life in individuals with CRDs. However, PR remains grossly underutilized all around the world. This study aimed to analyze the research trends on PR over the past 10 years.
    Methods: The publications related to pulmonary rehabilitation in the Web of Science Core Collection (WoSCC) from 2011 to 2020 were searched. VOSviewer (1.6.15) and CiteSpace Software (5.5.R2) were used to analyze authors and co-cited authors, countries and institutions, journals and co-cited journals, co-cited references, and keywords.
    Results: A total of 4,521 publications were retrieved between 2011 and 2020, and the number of annual publications on pulmonary rehabilitation has shown an overall upward trend in the past decade. The USA was the most productive country, the University of Toronto from Canada was both the first in publications and citations. Spruit MA was both the most productive author and the one with the highest number of co-citations. The first productive journal was the International Journal of Chronic Obstructive Pulmonary Disease, while the first co-cited journal was the American Journal of Respiratory and Critical Care Medicine. The hot keywords were grouped into three clusters, while "Asthma" and "Respiratory society statement" were determined as the frontier topics.

    The Most-Cited Ankle Arthroplasty Implant Articles.
    Kevin Mo, James R Ficke.
       Background: Citation analysis is a useful way of evaluating the impact, importance, and merit of articles within a medical specialty. Our study identified and analyzed the most-cited articles on ankle arthroplasty implants to evaluate their importance in the field of ankle arthroplasty research.
    Methods: Using the keywords "ankle arthroplasty" and "ankle replacement" and the search period 1970-2021, we found 3728 articles on ankle arthroplasty implants in the Scopus, Web of Science, and MEDLINE/PubMed databases. We included original articles, reviews, clinical trials, and case reports in the study. We retrieved the 50 most-cited articles published during the time frame and then screened them for studies of specific ankle arthroplasty implants and their postoperative outcomes. We also recorded and analyzed the articles' subjects, authorship, journals, countries of origin, and years of publication.
    Results: The 50 most-cited articles were published between 1983 and 2014, with the majority (33) published between 2000 and 2010. They generated 9012 citations in the literature. The most-cited study accounted for 497 citations; the mean number of citations per article was 180.24 ± 76.24. Twenty-three (46%) of the articles addressed postoperative outcomes following a specific type of arthroplasty implant. Arthroplasty implant studies accounted for 4726 citations, or 52.4% of the citations of the 50 articles. The most frequently studied arthroplasty implant was STAR (15), followed by Agility (7), Buechel Pappas (5), and Salto (4). STAR accounted for 3311 citations, or 37% of the total citations of the 50 articles.
    Conclusion: Ankle arthroplasty research has made great progress in the past 2 decades, particularly in the area of postoperative outcomes of specific ankle implants, but continued research and publication on additional arthroplasty implants should become a priority.
    Level of Evidence: Level V, Review Article.

    The Most Highly Cited Publications on Basketball Originate From English-Speaking Countries, Are Published After 2000, Are Focused on Medicine-Related Topics, and Are Level III Evidence.
    Zachary D Griffin, Jordan R Pollock, M Lane Moore, Kade S McQuivey, Jaymeson R Arthur, Anikar Chhabra.
       Purpose: To identify the 50 most highly cited research publications in the sport of basketball.
    Methods: Using the Clarivate Analytics Web of Knowledge database and the search term "basketball", we identified 2,704 articles. These articles were filtered by the total number of citations and the top 50 most cited articles with a central focus on basketball were selected for this analysis. For each article, we further identified and analyzed author name, publication year, country of origin, journal name, article type, main research topic area, competitive level, gender of study population, and the level of evidence.
    Results: Medicine-related topics, particularly those involving knee injuries, are more common than nonmedical topics (coaching, sports psychology etc.) among the highest cited articles. Articles originated from 13 different countries, with 48% originating in the United States. Only four authors had more than one article included in the top 50 most cited articles.
    Conclusion: A majority of the top 50 research articles were from English-speaking countries, published after 2000, primarily focused on medicine-related topics, and were Level III evidence. Publications examining knee injuries were the most highly cited and appear to be of high interest to current investigators. The prestige of an author's name appeared to be less influential to the number of citations.
    Clinical Relevance: The top 50 most cited articles list will provide researchers, medical students, residents, and fellows with a foundational list of the most important and influential academic contributions to the basketball literature.

    Mapping Knowledge Landscapes and Emerging Trends of the Links Between Bone Metabolism and Diabetes Mellitus: A Bibliometric Analysis From 2000 to 2021.
    Kunming Cheng, Qiang Guo, Weiguang Yang, Yulin Wang, Zaijie Sun, Haiyang Wu.
       Background: Diabetes mellitus (DM) have become seriously threatens to human health and life quality worldwide. As a systemic metabolic disease, multiple studies have revealed that DM is related to metabolic bone diseases and always induces higher risk of fracture. In view of this, the links between bone metabolism (BM) and DM (BMDM) have gained much attention and numerous related papers have been published. Nevertheless, no prior studies have yet been performed to analyze the field of BMDM research through bibliometric approach. To fill this knowledge gap, we performed a comprehensive bibliometric analysis of the global scientific publications in this field.
    Methods: Articles and reviews regarding BMDM published between 2000 and 2021 were obtained from the Web of Science after manually screening. VOSviewer 1.6.16, CiteSpace V 5.8.R3, Bibliometrix, and two online analysis platforms were used to conduct the bibliometric and visualization analyses.
    Results: A total of 2,525 documents including 2,255 articles and 270 reviews were retrieved. Our analysis demonstrated a steady increasing trend in the number of publications over the past 22 years (R 2 = 0.989). The United States has occupied the leading position with the largest outputs and highest H-index. University of California San Francisco contributed the most publications, and Schwartz AV was the most influential author. Collaboration among institutions from different countries was relatively few. The journals that published the most BMDM-related papers were Bone and Osteoporosis International. Osteoporosis and related fractures are the main bone metabolic diseases of greatest concern in this field. According to co-cited references result, "high glucose environment," "glycation end-product" and "sodium-glucose co-transporter" have been recognized as the current research focus in this domain. The keywords co-occurrence analysis indicated that "diabetic osteoporosis," "osteoarthritis," "fracture risk," "meta-analysis," "osteogenic differentiation," "bone regeneration," "osteogenesis," and "trabecular bone score" might remain the research hotspots and frontiers in the near future.
    Conclusion: As a cross-discipline research field, the links between bone metabolism and diabetes mellitus are attracting increased attention. Osteoporosis and related fractures are the main bone metabolic diseases of greatest concern in this field. These insights may be helpful for clinicians to recognize diabetic osteopenia and provide more attention and support to such patients.

    Bibliometric and visualized analysis of the top 100 most-cited articles on anterior cervical surgery.
    Junbo He, Tingkui Wu, Chen Ding, Beiyu Wang, Ying Hong, Hao Liu.
      Anterior cervical surgery (ACS) owes its development to various pioneering individuals whose revolutionary works form key advances and guide current medical decisions. This bibliometric study aimed to identify, analyse and visualize the main features of the most-cited papers in ACS. The citation count for the top 100 most-cited articles ranged from 148 to 1,197, and citations per year ranged from 3.1 to 89.8. The articles were published from 1958 to 2016, with the 2000s being the most active decade. There was an inverse correlation between the average citations per year since publication and article age. The oldest as well as most-cited two articles were both published in 1958 by Smith and Robinson, and Cloward, respectively. In their studies, the authors individually described the technique of anterior cervical discectomy with fusion (ACDF). The most popular keywords were: 'fusion' (22), 'spine' (20), 'cervical spine' (16), 'complications' (15), 'arthrodesis' (13), 'interbody fusion' (13), 'bone morphogenetic protein' (13), and 'radiculopathy' (12). ACDF was the most frequent surgical procedure (80%), while cervical disc arthroplasty is of gradual greater impact. The surgical techniques of ACDF have remained unaltered for over 60 years. More attempts are needed to promote its development. Cite this article: EFORT Open Rev 2021;6:1203-1213. DOI: 10.1302/2058-5241.6.210074.

    Potential Markers of Neurocognitive Disorders After Cardiac Surgery: A Bibliometric and Visual Analysis.
    Linna Ji, Fang Li.
       Background: Identifying useful markers is essential for diagnosis and prevention of perioperative neurocognitive disorders (PNDs). Here, we attempt to understand the research basis and status, potential hotspots and trends of predictive markers associated with PNDs after cardiac surgery via bibliometric analysis.
    Methods: A total of 4,609 original research articles and reviews that cited 290 articles between 2001 and 2021 were obtained from the Web of Science Core Collection (WoSCC) as the data source. We used the software CiteSpace to generate and analyze visual networks of bibliographic information, including published years and journals, collaborating institutions, co-cited references, and co-occurring keywords.
    Results: The number of annual and cumulative publications from 2001 to 2021 has been increasing on the whole. The Harvard Medical School was a very prolific and important institution in this field. The journal of Ann Thorac Surg (IF 4.33) had the most publications, while New Engl J Med was the most cited journal. Neuron-specific enolase (NSE), S100b and kynurenic acid (KYNA) were frequently discussed as possible markers of PNDs in many references. Cardiopulmonary bypass (CPB) was a keyword with high frequency (430) and sigma (6.26), and inflammation was the most recent burst keyword.
    Conclusion: Potential markers of PNDs has received growing attention across various disciplines for many years. The research basis mainly focuses on three classic biomarkers of S100b, NSE, and KYNA. The most active frontiers are the inflammation-related biomarkers (e.g., inflammatory cells, cytokines, or mediators) and surgery-related monitoring parameters (e.g., perfusion, oxygen saturation, and the depth of anesthesia).

    A Bibliometric Analysis of the Hotspots Concerning Stem Cell Extracellular Vesicles for Diabetes in the Last 5 Years.
    Haiyuan Qiu, Rong Guo, Yuanwen Zhang, Jianghui Ying, Yazhou Yan, Jiachao Xiong.
       Background: Diabetes mellitus (DM) is a metabolic disease that endangers human health, and its prevalence is exploding and younger. Stem cell-derived extracellular vesicles (SC-EVs) have a repair function similar to SCs and no risk of tumor formation, which have been widely used in the repair of DM and its complications. We aim to map the hot trends of SC-EVs for the treatment of DM and providing directions for future research.
    Methods: We screened all relevant publications on SC-EVs for DM from the Web of Science (Wos) during 2017-2021, and research trends in this field were analyzed by VOSviewer and CiteSpace.
    Results: A total of 255 articles related to SC-EVs for DM were screened out according to the search strategy. China (122 publications and 2,759 citations) was the most productive country, followed by the USA (50 publications and 1,167 citations) and Italy (16 publications and 366 citations). The top five institutions with the most publications were located in Italy and China, with Turin University being the most productive. The journals Stem Cell Research and Therapy and International Journal of Molecular Sciences published most of the studies on SC-EVs for DM. ASHOK KUMAR published the majority of articles in this field, while QING LI was the most cited. Cluster analysis indicated that the current research trend is more focused on the repair mechanism and clinical translation of exosomes and their related preparations in promoting DM and its complications.
    Conclusion: In this study, a comprehensive summary and analysis of the global research trends of SC-EVs used in DM and its complications was performed. In the past 5 years, relevant high-quality publications in this field have increased significantly, and SC-EVs have a good prospect for development in the treatment of DM and its complications.

    Nuria Monteagudo-Martínez, Julián Solís García Del Pozo, Ichiro Ikuta, Maria Francisca Galindo, Joaquín Jordán.
      WHAT IS KNOWN AND OBJECTIVE?: Dalbavancin is used against gram-positive pathogens such as Staphylococcus aureus in acute bacterial skin and skin-structure infections. METHODS: Our main goal was to identify the key articles sustaining the current knowledge of this drug's therapeutic possibilities through a bibliometric analysis of the available literature. RESULTS AND DISCUSSION: On 15 March 2021, we searched the Web of Science electronically for documents that contain within its title the term "dalbavancin." We found a total of 675 documents that average 20.23 citations/publication with a density of 682.60 citations per/year, yielding an h-index of 58. After ranking them by the number of times cited, we extracted the top 100 most-cited records (T100). Number of citations/publication ranged from 13 to 231, publication years were 2002-2019, with the top-cited article published in 2014. All T100 publications were written in English. JMI Laboratories was the institution with the most articles in the T100 (22 documents), and the United States was the top country (75 documents). Five authors participated in at least five of the T100, led by Jones RN with 20 articles. Positions #1, #2, #5, and #9 were clinical trials for acute bacterial skin and skin structure infections (ABSSSI), the on-label indication for dalbavancin. Only one article in the top 10 (T10) was an off-label indication that was published in 2005 with 186 citations, and occupied the third position among the T100. Using the VOSviewer© programme, we observed that the most used keywords were: dalbavancin, lipoglycopeptide, gram-positive, osteomyelitis, vancomycin, and MRSA. WHAT IS NEW AND CONCLUSIONS?: Our study identifies the most significant research on dalbavancin, including the highest impact publications, and highlights the recent trend of dalbavancin in new therapies. The T10 articles include the most important dalbavancin clinical trials, along with other studies and reviews that support the growing role of this antibiotic in clinical use. Emphasis has been on the favourable pharmacokinetic profile that allows administration once-weekly, with minimal risk of severe adverse events.

    Sketching the Landscape of Speech Perception Research (2000-2020): A Bibliometric Study.
    Juqiang Chen, Hui Chang.
      Based on 6,407 speech perception research articles published between 2000 and 2020, a bibliometric analysis was conducted to identify leading countries, research institutes, researchers, research collaboration networks, high impact research articles, central research themes and trends in speech perception research. Analysis of highly cited articles and researchers indicated three foundational theoretical approaches to speech perception, that is the motor theory, the direct realism and the computational approach as well as four non-native speech perception models, that is the Speech Learning Model, the Perceptual Assimilation Model, the Native Language Magnet model, and the Second Language Linguistic Perception model. Citation networks, term frequency analysis and co-word networks revealed several central research topics: audio-visual speech perception, spoken word recognition, bilingual and infant/child speech perception and learning. Two directions for future research were also identified: (1) speech perception by clinical populations, such as hearing loss children with cochlear implants and speech perception across lifespan, including infants and aged population; (2) application of neurocognitive techniques in investigating activation of different brain regions during speech perception. Our bibliometric analysis can facilitate research advancements and future collaborations among linguists, psychologists and brain scientists by offering a bird view of this interdisciplinary field.

    Knowledge Mapping of the Phytoremediation of Cadmium-Contaminated Soil: A Bibliometric Analysis from 1994 to 2021.
    Xiaofeng Zhao, Mei Lei, Runyao Gu.
      Cadmium pollution of soil threatens the environmental quality and human health. Phytoremediation of cadmium-contaminated soil has attracted global attention in recent decades. This study aimed to conduct a comprehensive and systematic review of the literature on phytoremediation of cadmium-contaminated soil based on bibliometric analysis. A total of 5494 articles published between 1994 and 2021 were retrieved from the Web of Science Core Collection. Our knowledge mapping presented the authors, journals, countries, institutions, and other basic information to understand the development status of phytoremediation of cadmium-contaminated soil. Based on a keyword cluster analysis, the identified major research domains were "biochar", "Thlaspi caerulescens", "endophytic bacteria", "oxidative stress", "EDTA", and "bioconcentration factor". Overall, this study provided a detailed summary of research trends and hotspots. Based on the keyword co-occurrence and burst analysis, the core concepts and basic theories of this field were completed in 2011. However, the pace of theoretical development has been relatively slow. Finally, future research trends/frontiers were proposed, such as biochar addition, rhizosphere bacterial community manipulation, cadmium subcellular distribution, and health risk assessment.

    Bibliometric Trends in Open Surgical and Endovascular Cerebrovascular Research.
    Jason Yuen, Mohamed Sobhi Jabal, Luis E Savastano, David F Kallmes.
      The last decade has witnessed a major expansion in endovascular interventions concurrent with a contraction of open neurovascular surgeries. Whether research efforts have also shifted from open to endovascular neurosurgery is an effect that has not been explored extensively. Understanding the bibliometric trend is important for researchers, funding agencies, and publishing journals. The aim of this review is to explore this potential shift. We compared the bibliometrics of open cerebrovascular and endovascular research articles published in two neurosurgical journals (Journal of Neurosurgery, Neurosurgery) and two neuroradiological journals (Journal of Neurointerventional Surgery, American Journal of Neuroradiology). Data were collected between September 26, 2021, and October 18, 2021. Articles published in 2011, 2013, 2015, 2017, and 2019 from the journals were screened. Neurovascular articles were classified into open surgical, endovascular, or mixed. Bibliometric parameters were collected via SCOPUS and journals' websites. A total of 8,018 articles were screened, of which 1,551 were included (16.2% open, 62.2% endovascular, 21.5% mixed). Most articles were related to aneurysms (76%). Open-access status correlated with increased citations (p<0.001) and Altmetric (p<0.001), which measures online activity. Comparing 2011 and 2019, the article distribution (open/endovascular/mixed) has changed significantly (χ2 test, p=0.002), with open articles dropping from 23.6% (68/288) to 12.9% (44/342) and endovascular articles rising from 56.6% (163/288) to 65.8% (225/342). Using the Kruskal-Wallis test, the citation distribution is different across the three groups in 2019 (p<0.001), favoring endovascular articles, but not in the other years. Our study suggests a trend of diminishing open neurovascular research output and increasing endovascular research output, in terms of both the number of articles and the citations. More time for citation accumulation may be required to verify this trend.

    The research status of central venous catheterization-associated thrombosis: a bibliometrics analysis.
    Yan Sun, Xuedan Li, Yan Zhang, Sheng Tang.
       Background: Central venous catheters are associated with a significantly increased risk of venous thrombosis due to a variety of factors. This bibliometric study analyzed the current research status in the field of central venous catheterization associated thrombosis.
    Methods: Related literatures in the Science Citation Index Expanded (SCI-E) database were identified using the search terms "central venous catheter" and "thrombosis". The CiteSpace software was used to analysis literature data including country, institution, author, and journal distribution characteristics, as well as the use of keywords, and the number of times the country, institution, author, or journal were cited. Co-occurrence maps between countries, institutions, authors, and keywords were constructed.
    Results: A total of 2,810 related literature records were identified, with a total of 29,920 citations. The number of documents and the number of citations generally showed an increasing annual trend. These documents were mainly published from developed countries in Europe and North America, including USA, Britain, Italy, and France. Cooperation between institutions tended to be limited to the same country, and collaboration between authors tended to be within the same institutions. Keyword analysis demonstrated that in recent years, the research on thrombosis related to central venous catheterization has been more targeted, with an increasing focus on evidence-based medicine.
    Conclusions: Future research may focus more on the prevention, early diagnosis, and treatment of asymptomatic central venous catheterization-related thrombosis.

    Joining the meta-research movement: A bibliometric case study of the journal Perspectives on Medical Education.
    Lauren A Maggio, Stefanie Haustein, Joseph A Costello, Erik W Driessen, Anthony R Artino.
       PURPOSE: To conduct a bibliometric case study of the journal Perspectives on Medical Education (PME) to provide insights into the journal's inner workings and to "take stock" of where PME is today, where it has been, and where it might go.
    METHODS: Data, including bibliographic metadata, reviewer and author details, and downloads, were collected for manuscripts submitted to and published in PME from the journal's Editorial Manager and Web of Science. Gender of authors and reviewers was predicted using Genderize.io. To visualize and analyze collaboration patterns, citation relationships and term co-occurrence social network analyses (SNA) were conducted. VOSviewer was used to visualize the social network maps.
    RESULTS: Between 2012-2019 PME received, on average, 260 manuscripts annually (range = 73-402). Submissions were received from authors in 81 countries with the majority in the United States (US), United Kingdom, and the Netherlands. PME published 518 manuscripts with authors based in 31 countries, the majority being in the Netherlands, US, and Canada. PME articles were downloaded 717,613 times (mean per document: 1388). In total 1201 (55% women) unique peer reviewers were invited and 649 (57% women) completed reviews; 1227 (49% women) unique authors published in PME. SNA revealed that PME authors were quite collaborative, with most authoring articles with others and only a minority (n = 57) acting as single authors.
    DISCUSSION: This case study provides a glimpse into PME and offers evidence for PME's next steps. In the future, PME is committed to growing the journal thoughtfully; diversifying and educating editorial teams, authors, and reviewers, and liberating and sharing journal data.

    Bibliometric Analysis of Literature on Physical Activity and COVID-19.
    Apichai Wattanapisit, Manas Kotepui, Sanhapan Wattanapisit, Noah Crampton.
      The coronavirus disease 2019 (COVID-19) pandemic induced a sudden surge in COVID-19 related publications. This bibliometric analysis aimed to analyze literature on physical activity and COVID-19 published in the PubMed database. The search terms ((physical activity [MeSH Terms] OR physical inactivity [MeSH Terms]) AND COVID-19 [MeSH Terms]) were applied to obtain publications from the inception of PubMed to February 2022. The analyses included the year of publication, type of publication, and origin of publication by country, region, and country income. The research areas were analyzed for research articles and systematic reviews. Of 1268 articles, 143 articles were excluded, and 1125 articles were analyzed. A total of 709 articles (63.02%) were published in 2021. A majority of publications were research articles (n = 678, 60.27%). The USA (n = 176, 15.64%), countries in the European Region (n = 496, 44.09%), and high-income countries (n = 861, 76.53%) were dominant publishing countries. Of 699 research articles and systematic reviews, surveillance and trends of physical activity were the main research area, followed by health outcomes, and correlates and determinants of physical activity. There is a wide gap in publication productivity in the field of physical activity and health during the pandemic among different countries' economic statuses.

    The evolving gender distribution in authorship over time in American surgery.
    Thuy B Tran, Paul Wong, Mustafa Raoof, Kurt Melstrom, Yuman Fong, Laleh G Melstrom.
       BACKGROUND: The need for gender parity within academic surgery has resulted in an analysis of the trends in female authorship in the American general surgery literature.
    METHODS: Original articles from five American surgical journals from 1997, 2007, and 2017 were reviewed. Trends in the proportion of female authors were evaluated.
    RESULTS: There was an incremental increase in female first authors over the three time periods (15% in 1997, 32.2% in 2007, and 52.7% in 2017; P < 0.001). The proportion of articles by female senior authors also increased over the study periods (18.7% in 1997, 28.8% in 2007, and 52.6% in 2017; P < 0.001). However, there were fewer female authors with basic science research publications than males (17.4% vs. 82.6%, P < 0.001).
    CONCLUSIONS: The academic productivity of female surgeons have increased over time likely due to an increase in the number of female academic surgeons in recent years. These findings are encouraging and demonstrate progress in female representation in surgery.

    Dentinal microcracks induced by endodontic procedures: A scientometric and bibliometric analysis.
    Stéphanie Quadros Tonelli, Kênia Soares de Toubes, André Maués Brabo Pereira, Antônio Carlos de Oliveira Miranda, Letícia Ladeia Fernandes, Eduardo Nunes, Frank Ferreira Silveira.
       Background: Due to the large number of publications relating the occurrence of dental microcracks to endodontic procedures, this bibliometric study evaluated the scientific pattern and trends in literature and provided an overview of scientific production in this context.
    Aim: To analyze, quantify, and characterize the scientific production and trends of published articles evaluating dentinal microcracks formation after endodontic treatment procedures between 2010 and 2020 using bibliometric indicators.
    Materials and Methods: Published articles were found by the search in the Medline (PubMed) and Scopus database using the combination of the following keywords: Dentinal crack OR Dentinal Microcrack OR Crack formation OR Dentin Defect AND Endodontic treatment OR Root canal preparation OR Canal Preparation OR Root canal treatment OR endodontic procedures. The search was also conducted in the Journal of Endodontics and International Endodontic Journal. After inclusion and exclusion criteria application, data from all studies included were collected.
    Results: Among the 556 results after the search, 45 studies were included and analyzed in this bibliometry. No trend was observed in terms of the increasing number of articles over time. Most of them used an in vitro design, compared the effect of different endodontic techniques/systems for root canal instrumentation on dentinal microcracks formation, and were conducted in Turkey, Brazil, and India. Journal of Endodontics and International Endodontic Journal were the main journals with a higher number of articles published. Interestingly, studies conducted with some funding did not lead to higher citation numbers. Moreover, a relevant proportion of studies did not consider the inclusion of control groups, baseline evaluation, or statistical analysis. Micro-CT was the main technique used to evaluate microcrack presence.
    Conclusion: Microcrack formation after the use of different endodontic techniques/systems has been constantly evaluated in the literature. There is a pattern of methodologies used, which may explain the concentration of these studies in specific journals and countries.

    Analysis and Visualization of Research on Resilient Cities and Communities Based on VOSviewer.
    Yu-Jie Huang, Shuo Cheng, Fu-Qiang Yang, Chao Chen.
      To objectively grasp the current situation and development trend of resilient cities or communities (RC) research. The articles in Web of Science (WOS) Core Collection databases from 1995 to 2022 were used as a sample, and bibliometrics was used to statistically analyze the year of publication and number of articles, highly cited documents and keyword hotness in this field. VOSviewer was used to explore the knowledge graph of RC research documents. The results show that: the development process is roughly divided into 3 periods: no attention (1995-2004), starting (2005-2014), and rapid growth (2015-2021). The journal "Sustainability" and "International journal of disaster risk reduction" are the key journals publishing RC research. Serre and Shaw are the most productive authors. The USA is still the leading country in this field of RC. Colorado State Univ, Texas a&m Univ, and Delft Univ Technol are the main research institutions. The keyword analysis indicates the hot topics in different periods. Moreover, several limitations and some recommendations for future research on RC are also given based on this.

    Social Media Impact of Myopia Research.
    Cristina Alvarez-Peregrina, Cesar Villa-Collar, Clara Martinez-Perez, María Ibeth Peñaloza Barbosa, Miguel Ángel Sánchez-Tena.
       BACKGROUND: Myopia has become a public health issue worldwide. The fast increase in myopia prevalence in the last years has been accompanied by an increase in information through social and conventional media. This has led to the fight not only against a pandemic but also against the infodemic. The excess of information has made it increasingly difficult for health professionals to identify high-quality articles. Alternative Metrics are useful tools to identify publications that provoke attention to society. This research aims to study the impact that research on myopia has had on social media.
    METHODS: Almetric Explorer was used to make a search using "myopia" as a keyword. The 100 outputs with the highest attention were analyzed and correlated with the number of cites on Web of Science using Spearman's correlation coefficient.
    RESULTS: The top 100 Altmetric Attention Score were published in 47 journals and had a mean value of Altmetric Attention Score of 437.61 ± 718.33. The outputs were mostly discussed on Twitter, with a mean of 296.36 ± 1585.58 tweets and retweets, and a mean of 185.18 ± 211.57 readers in Mendeley. There was a low correlation between Altmetric Attention Score and Web of Science Cites for the top-100 outputs.
    CONCLUSIONS: although myopia is a research topic with a high interest in society, most cited articles are not those with the most impact on social media. Myopia researchers should make more effort in promoting their goals, and social media is a useful tool to share them.

    [Research hotspots and trends of Hedysari Radix: based on CiteSpace knowledge map].
    Xiao-Wen Mao, Zhi-Rong Gu, Yan Guo, Xin Lyu, Bin Ge.
      This study aims to summarize the research hotspots of Hedysari Radix and predict the research trend with bibliometric methods, which is expected to serve as a reference for future research. CiteSpace V 5.8.R2 was employed for visualization of the number, authors, author affiliations, journals, funds, and keywords of the Chinese and English articles on Hedysari Radix in China National Knowledge Infrastructure(CNKI) and Web of Science(WOS) from 2001 to 2021. A total of 693 Chinese articles and 167 English articles were finally included. According to the knowledge map, most of the articles were from China and the authors from China had a close cooperation with the related institutions in the United States and Australia. Gansu University of Chinese Medicine(288) and Lanzhou University(151) respectively came out on top of the author affiliations in the number of Chinese and English articles. The journals were mainly about Chinese medicine, mainly including Chinese Journal of Information on Traditional Chinese Medicine and Evidence-based Complementary and Alternative Medicine. Papers(191 in Chinese and 60 in English) funded by National Natural Science Foundation of China were the most. Keyword analysis suggested that the main research directions were pharmacological action and mechanism, component analysis, content determination, and industrialization of medicinal materials of Hedysari Radix and that the research hotspots were the prevention and treatment of diabetes and its complications, tumors, myocardial injury, liver fibrosis and other diseases with active components such as polysaccharides, ultrafiltrate, formononetin, and calycosin. The targets, signaling pathways, and genes related to the anti-tumor, heart protection, prevention and treatment of diabetes and its complications, and regulation of immunity should be further studied.

    A Bibliometric Analysis (2010-2020) of the Dental Scientific Literature on Chemo-Mechanical Methods of Caries Removal Using Carisolv and BRIX3000.
    Dana Cristina Bratu, Nicoleta Nikolajevic-Stoican, George Popa, Silvia Izabella Pop, Bianca Dragoș, Magda-Mihaela Luca.
      Reports in the literature have proposed and analyzed several minimally invasive techniques for caries removal in recent decades. In light of recent events surrounding the ongoing epidemiological context, concerns have been raised regarding the generation of aerosols during dental procedures. The aim of our research was to provide an overview of the scientific literature on the topic of chemo-mechanical caries removal (CMCR) methods, focusing on two products (Carisolv, BRIX3000), commercially available in Europe. A bibliometric analysis was used to investigate the scientific articles included in Web of Science (WoS) Core Collection database, published from January 2010 to December 2020. We analyzed the co-occurrence of all keywords (Author Keywords and the KeyWords Plus section), co-authorship and co-citation, using the free software VOSviewer. Our bibliometric analysis revealed a worldwide interest in the subject of chemo-mechanical methods of caries removal, which has transcended the area of pediatric dentistry. The analyzed studies have been conducted mainly in high-income countries that have developed sanitary policies regarding prevention and early treatment of carious lesions as a health priority.

    A Bibliometric Analysis of Low-Cost Piezoelectric Micro-Energy Harvesting Systems from Ambient Energy Sources: Current Trends, Issues and Suggestions.
    Mahidur R Sarker, Mohamad Hanif Md Saad, Amna Riaz, M S Hossain Lipu, José Luis Olazagoitia, Haslina Arshad.
      The scientific interest in piezoelectric micro-energy harvesting (PMEH) has been fast-growing, demonstrating that the field has made a major improvement in the long-term evolution of alternative energy sources. Although various research works have been performed and published over the years, only a few attempts have been made to examine the research's influence in this field. Therefore, this paper presents a bibliometric study into low-cost PMEH from ambient energy sources within the years 2010-2021, outlining current research trends, analytical assessment, novel insights, impacts, challenges and recommendations. The major goal of this paper is to provide a bibliometric evaluation that is based on the top-cited 100 articles employing the Scopus databases, information and refined keyword searches. This study analyses various key aspects, including PMEH emerging applications, authors' contributions, collaboration, research classification, keywords analysis, country's networks and state-of-the-art research areas. Moreover, several issues and concerns regarding PMEH are identified to determine the existing constraints and research gaps, such as technical, modeling, economics, power quality and environment. The paper also provides guidelines and suggestions for the development and enhancement of future PMEH towards improving energy efficiency, topologies, design, operational performance and capabilities. The in-depth information, critical discussion and analysis of this bibliometric study are expected to contribute to the advancement of the sustainable pathway for PMEH research.

    Exploring Environmental Health Inequalities: A Scientometric Analysis of Global Research Trends (1970-2020).
    Sida Zhuang, Gabriele Bolte, Tobia Lakes.
      Environmental health inequalities (EHI), understood as differences in environmental health factors and in health outcomes caused by environmental conditions, are studied by a wide range of disciplines. This results in challenges to both synthesizing key knowledge domains of the field. This study aims to uncover the global research status and trends in EHI research, and to derive a conceptual framework for the underlying mechanisms of EHI. In total, 12,320 EHI publications were compiled from the Web of Science core collection from 1970 to 2020. Scientometric analysis was adopted to characterize the research activity, distribution, focus, and trends. Content analysis was conducted for the highlight work identified from network analysis. Keyword co-occurrence and cluster analysis were applied to identify the knowledge domain and develop the EHI framework. The results show that there has been a steady increase in numbers of EHI publications, active journals, and involved disciplines, countries, and institutions since the 2000s, with marked differences between countries in the number of published articles and active institutions. In the recent decade, environment-related disciplines have gained importance in addition to social and health sciences. This study proposes a framework to conceptualize the multi-facetted issues in EHI research referring to existing key concepts.

    Altmetric score, reads, and citations in paediatric cardiology: do they correlate and what do they mean?
    Rohit S Loomba, Enrique G Villarreal, Riddhi D Patel, Daniela Santos-Cantu, Cordelia Alanis-Garza, Saul Flores, Juan S Farias, Jeffrey P Jacobs.
       INTRODUCTION: The primary objective of this study was to determine whether Altmetric score, number of reads, and citations for paediatric cardiology manuscripts correlate with one another. A secondary objective was to determine the extent to which factors mediated citation number for paediatric cardiology manuscripts.
    METHODS: Data for this study came from manuscripts published in Cardiology in the Young (2010-2021). Data were extracted by using data shared on the journal website. Spearman's correlation analyses were conducted between manuscript reads, citations, and Altmetric score. Regression analyses were conducted with number of citations as the dependent variable and year of publication, publication type, number of reads, and Altmetric score as independent variables.
    RESULTS: A total of 2642 manuscripts were included in the final analyses. Reads and citations had poor correlation (r-value 0.32); reads and Altmetric score had negligible correlation (r-value 0.26); and Altmetric score and citations had negligible correlation (r-value 0.07). Year of publication was independently associated with number of citations (β -0.95, p-value <0.01). Manuscript type was independently associated with number of citations (β 1.04, p-value <0.01). Number of reads was independently associated with citations (β 0.01, p-value <0.01). Altmetric score was independently associated with number of citations (β 0.05, p-value <0.01).
    CONCLUSION: This study describes the correlation of reads, citations, and Altmetric score in manuscripts published in Cardiology in the Young, demonstrating poor correlation, at best, between these metrics. Each bibliometric index seems to represent a different phenomenon of manuscript consumption. No single bibliometric index in isolation offers ample representation of manuscript consumption.

    Global research production pertaining to gastrointestinal involvement in COVID-19: A bibliometric and visualised study.
    Sa'ed H Zyoud, Samah W Al-Jabi, Moyad Jamal Shahwan, Ammar Abdulrahman Jairoun.
       BACKGROUND: Coronavirus disease 2019 (COVID-19) is a global pandemic that can cause diarrhoea, nausea/vomiting, and abdominal pain, among other gastrointestinal (GI) symptoms.
    AIM: To perform a bibliometric analysis of the global research production pertaining to GI involvement in COVID-19.
    METHODS: The Scopus database was used to search the global literature on GI involvement in COVID-19 during 2020. A bibliometric review of these publications was also performed using VOSviewer.
    RESULTS: Scopus had published 95615 documents on COVID-19 in all areas of research at the time of data collection. In total, 1267 publications on the topic of GI and COVID-19 were identified. Research articles (n = 606; 47.83%), letters (293; 23.13%), and reviews (186; 14.68%) were the most popular types of documents. The most productive countries and institutions in this field were the United States and Huazhong University of Science and Technology. The most cited paper was Xiao et al, which was published in Gastroenterology as a brief communication, with 798 citations. This paper provides evidence for GI infection of COVID-19 and its possible faecal-oral transmission route. In the term cluster analysis, there were two frontiers in this field: GI manifestations among COVID-19 patients and the implications of COVID-19 for the gastroenterologist.
    CONCLUSION: GI manifestations among COVID-19 patients and implications of COVID-19 for gastroenterologists were of interest, especially in the early stages of the pandemic.

    Bibliometrics Analysis in English and Chinese Literature on Drowning in Forensic Medicine from 1991 to 2020.
    Hai-Xing Yu, Ji Zhang, Yong-Zheng Zhu, Qi Cheng, Xiao-Tian Yu, Ping Huang, Yong-Hui Dang, Ge-Fei Shi.
       OBJECTIVES: To explore the research hotspots and development trends of the field of forensic drowning from 1991 to 2020 by bibliometrics methods.
    METHODS: Based on Web of Science, CNKI database, Wanfang Data knowledge service platform, python 3.9.2, CiteSpace 5.8.R3, Gephi 0.9.2, etc. were used to analyze the publishing trends, countries/regions, institutions, authors and topics of the study on drowning.
    RESULTS: A total of 631 English literature were obtained, including 59 articles from Chinese authors, and 386 Chinese literature were obtained. The Chinese and English journals with the largest number of related literatures were Chinese Journal of Forensic Science (80 articles) and Forensic Science International (106 articles), respectively. Japan published the most articles in English, and China ranked third. Osaka City Univ (Japan, 28 articles) published the most English articles, and Guangzhou Forens Sci Inst (China, 22 articles) ranked second. Among Chinese literature, Guangzhou Forens Sci Inst (32 articles) published the most. The topic analysis of Chinese and English literature showed that diatom examination, virtual autopsy, postmortem biochemical examination, the nature of death, and postmortem submersion interval were the hot spots of current research, but English literature had more studies on new technologies and methods, while Chinese literature was more inclined to practice, application and experience summary.
    CONCLUSIONS: The number of literature in forensic medicine on drowning is relatively stable. The scope of international and domestic collaborations in this field is still limited. The automated examination of diatoms, the establishment of diatom DNA barcodes and virtual autopsy will be the most important research hotspots in the coming period and are expected to achieve breakthroughs in drowning diagnosis, drowning location inference, postmortem submersion interval estimation, etc.

    Global Bibliometric Developments on Solid Waste Recycling in Concrete Construction Engineering.
    Xiaoshan Zhang, Yue Xiao, Yongjie Xue, Jian Liu, Zongwu Chen, Ronghui Zhang.
      The precise and visual analysis of solid waste recycling in concrete construction engineering is critical for the development of ecological civilization and for the secure supply of resources. This research makes a bibliometric analysis of the solid waste application in concrete construction engineering from 2000 to 2021 based on the Web of Science. The global bibliometric status, current research focus and future directions were used to indicate the global development of solid waste recycling in concrete construction engineering. The most reused solid wastes and most solid waste productive regions were concluded with this bibliometric analysis. China is far ahead of other countries in solid waste recycling in all aspects and heavy metal is one of the most prominent solid waste themes in China. By analyzing the most studied solid waste, fly ash appears to be the most popular and is widely used; half of the top ten-cited papers are correlated with it.

    Trends on Microalgae-Fungi Consortia Research: An Alternative for Biofuel Production?
    Ana Beatriz Lobo-Moreira, Solange Xavier-Santos, Luciana Damacena-Silva, Samantha Salomão Caramori.
      The utilization of microalgae and fungi on an industrial scale is a challenge for researchers. Based on the question "how fungi have contributed to microalgae research?," we verified the scientific trends on microalgae-fungi consortia focused on biofuels production by searching for articles on the Web of Science and Scopus databases through the terms "microalgae*" or phytoplankton and "fung*." We found 1,452 articles published between 1950 and 2020; since 2006, the publication numbers have increased rapidly. The articles were published in 12 languages, but most were written in English (96.3%). Among 72 countries, China (360 articles), USA (344), and Germany (155) led the publication rank. Among the 10 most-prolific authors, 8 were Chinese, like 5 of the most-productive institutions, whereas the National Cheng Kung University was on the top of the list. The sources that published the most on the subject were: Bioresource Technology (96), PLoS ONE (28), and Science of the Total Environment (26). The keyword analysis emphasized the magnitude of applications in microalgae-fungi consortia research. Confirming this research question, biofuels appeared as a research trend, especially biodiesel, biogas, and related terms like lipid, lipid accumulation, anaerobic digestion, and biogas upgrading. For 70 years, articles have been published, where China and the United States seem to dominate the research scenario, and biodiesel is the main biofuel derived from this consortium. However, microalgae-based biofuel biorefinery is still a bottleneck on an industrial scale. Recent environmental challenges, such as greenhouse gas mitigation, can be a promising field for that microalgae-fungi application.

    Evaluating the Academic Influence of Orthopedic Surgeons in Spinal Literature Through Relative Citation Ratio.
    Zachary T Grace, Harsh Patel, Ali M Omari, Angeline Sanders, Nareena Imam, John D Koerner.
       INTRODUCTION:  The innovative iCite tool applies the relative citation ratio (RCR) to gauge the time and field-adjusted scientific influence of a publication. This study examines scholarly effects on spine surgery to distinguish the impact made by orthopedic surgeons, neurosurgeons, and several other specialists.
    MATERIALS AND METHODS:  From 2013 to 2017, 100 of the highest RCR-rated articles were gathered for each of the following terms: cervical disc herniation (CDH), lumbar disc herniation (LDH), lumbar spinal stenosis (LSS), neurogenic claudication (NC), radiculopathy (RAD), and sciatica (SC). The first, second, and last authors were queried for background and academic qualifications and placed into the following specialty categories: orthopedic surgery, neurosurgery, pain management, medicine, and others. To provide an alternative degree of influence, the Scopus database was employed to classify the h-index associated with each author.
    RESULTS:  Across the six search terms, there were 526 orthopedic surgeons among 1,730 authors (30.4%), with the highest representation in LSS (118/290, 40.7%), and the lowest in SC (45/286, 15.7%). Orthopedics was the most influential specialty across all six research terms by median RCR (p = 0.012). Compared to their neurosurgical counterparts, orthopedic authors had a greater influence in CDH (3.93 vs. 2.63, p = 0.0492), LDH (5.10 vs. 4.99, p = 1.0000), NC (2.16 vs. 1.40, p = 0.2370), and SC (3.35 vs. 3.04, p = 0.5285), but had a lower influence in LSS (5.13 vs. 5.32, p = 0.7736) and RAD (5.03 vs. 6.05, p = 0.3938).
    CONCLUSION:  Orthopedic surgeons lead other specialties when determining scholarly influence through RCR across six of the pre-designated research domains within spine surgery. For orthopedics, a modest influence in LSS and RAD may suggest potential areas of future focus. The use of bibliometrics to analyze available literature enables us to identify other specialties that have contributed to our field and promote interdisciplinary collaboration.

    Global Trends in Physical-Activity Research of Autism: Bibliometric Analysis Based on the Web of Science Database (1980-2021).
    Xiao-Wei Feng, Maryam Hadizadeh, Jadeera Phaik Geok Cheong.
      The World Health Organization has identified nervous system diseases as one of the biggest public health problems, including autism spectrum disorder (ASD). Considering the extensive benefits of physical activity (PA), the literature on the PA research of ASD has increased each year, but there is a lack of bibliometric analyses in this field. To investigate the research achievements worldwide, this paper adopts bibliometrics to analyze the trend in the academic literature on the PA research of ASD published from 1980 to 2021. The documents were retrieved from the Web of Science database, and the search strategy was to combine the keywords related to "physical activity" and "autism spectrum disorder" by using the Boolean operator tools "OR" and "AND" in the title. A total of 359 English documents were retrieved. Microsoft Excel, Data Wrapper, VOSviewer, and Biblioshiny were used for the visual analysis. We found that the number of published documents increased the fastest from 2017 to 2021, which may be due to the promulgation of the Global Action Plan for Physical Activity 2018-2030 and the influence of COVID-19 on the world. The United States and the University of California systems are in the leading position in this field. Cooperation among countries with different levels of development will help to jointly promote the PA research progress on ASD. The focus themes include "individual effect", "social support" and "activity dose". The analysis of the frontier topic points out that researchers are paying increasing attention to how to improve the health and physical fitness of this group through PA. This research clearly puts forward a comprehensive overview, theme focus, and future trends in this field, which may be helpful to guide future research.

    Presentation of the Prehospital Emergency Research Network and an analysis of bibliometric indicators for scientific productivity in out-of-hospital care.
    Mª Elena Castejón-de la Encina, Ricardo Delgado Sánchez, Fernando Ayuso Baptista, Fernando López Mesa, Rafael Castro Delgado.
       TEXT: Through research we advance scientific understanding and its application in medical practice. Many of the advances in out-of-hospital emergency care are extracted from hospital settings, perhaps because of the difficulties inherent to our prehospital environments: heterogeneity, obstacles to data collection, biases not controlled for, among other limitations. Research networks offer opportunities to create connections among researchers and facilitate homogeneous data collection. We introduce the Prehospital Emergency Research Network (whose Spanish acronym is RINVEMER) and analyze bibliometric indicators of Spanish productivity in this specialty. Since 1975, a total of 512 articles have been published in journals with impact factors by 381 authors working in Spanish prehospital settings. The first such article published after the creation of the Web of Science appeared in 1999. The 61 authors affiliated with the emergency health services of Andalusia, a public company, made up the largest single author group. Publication productivity increased substantially in the last 2 years. A total of 63 PhD theses have been registered in this specialty - 8 of them at the University of Oviedo. With the growth of Spanish out-of-hospital research in recent years, we expect the creation of the RINVEMER network to improve collaboration among our researchers.

    Technique Articles Are More Effective at Increasing Social Media Attention in Comparison With Original Research Articles: An Altmetrics-Based Analysis.
    Amar S Vadhera, Jonathan S Lee, Isabel L Veloso, Harsh Singh, Nicholas A Trasolini, Kyle N Kunze, Safa Gursoy, Andrew G Geeslin, Nikhil N Verma, Jorge Chahla.
       Purpose: To compare social media attention and citation rates between technique articles and matched original research articles (ORAs) regarding surgical procedures.
    Methods: All technique articles published from August 2019 through July 2020 in the free, electronic versions of Arthroscopy Techniques and JBJS Essential Surgical Techniques were matched by topic to articles in the "Original Research" sections of Arthroscopy, Sports Medicine, and Rehabilitation and JBJS Open Access in a 4:1 ratio within this time frame. The primary outcome was the Altmetric Attention Score (AAS). Secondary outcomes included citations, bibliometrics, and social media metrics. Independent t tests were used to compare primary and secondary outcomes between technique articles and ORAs. A multivariate linear regression analysis was performed to determine the association between article type and social media attention while controlling for confounding bibliometric characteristics.
    Results: A total of 285 matched research articles (n = 57, 20.0%) and technique articles (n = 228, 80.0%) were included. The mean AAS among all technique articles was 3.63 ± 10.08 (range, 0-96) whereas the mean AAS among all ORAs was 1.30 ± 3.98 (range, 0-25), representing a statistically significant difference (P = .016). The mean citation rate among all technique articles was not significantly different from that among ORAs (P = .73). Multivariate linear regression analysis showed a statistically significant positive association between AAS and article type, with an additional mean increase in the AAS of 2.91 (95% confidence interval, 0.04-5.77; P = .047) for every technique article compared with an ORA. Furthermore, a significant positive relation was noted between the article origin and the AAS, with an increase in the AAS of 3.00 (95% confidence interval, 0.82-5.17; P = .007) for every article published in North America compared with an article originating from another continent.
    Conclusions: Technique articles resulted in significantly greater AASs and social media attention in comparison with open-access ORAs on similar topics. Publications that described technical procedures in a technique journal and studies from North America were positively associated with greater AASs and greater numbers of citations received by articles.
    Clinical Relevance: An improved understanding of how much attention is given to technique articles versus matched ORAs by social media may influence the methods authors and journals use for distributing content. The present study suggests that one option to increase the amount of social media attention received for a particular study may be to utilize an accompanying surgical technique video or illustrations as these are easily shareable on social media and offer rapid dissemination of knowledge, similar to that of an infographic. However, physicians who view multimedia within technique articles should be encouraged to review the accompanying articles and the supporting original research as a primary source before making changes in their clinical practice.

    Trends and frontiers of atmospheric duct research based on CiteSpace and deep learning.
    Jiajing Wu, Zhiqiang Wei, Jinpeng Zhang, Jiali Xu, Dongjing Jia, Hanjie Ji.
      The research of evaporation duct is of fundamental importance in the radar and signal communication industry. Particularly, in a real atmosphere environment, most of the radar holes cannot be corrected in time because of the persistent evaporation duct phenomenon. Thus, conducting evaporation duct research is a major concern of both academic and industrial communities. However, there is no descriptive research on the mobile communication in the marine and atmospheric environment. Numerous scholars and institutions have integrated atmospheric duct into multidisciplinary knowledge overview of the atmospheric duct in the existing published articles. The objective of this article is to explore the focus and status of atmospheric duct in-depth investigation and to grasp the frontiers and prospects of atmospheric duct research. A visual presentation of co-citation was adopted to realize the influence of authors, contributing institutions, keyword research hotspots, and frontier research based on co-citation network analysis. In addition, to identify the direction of atmospheric duct more accurately, the deep learning algorithm was adopted to conduct a comprehensive analysis of the future development trend of atmospheric duct.

    Mapping the Global Landscape of Long-Term Care Insurance Research: A Scientometric Analysis.
    Long Xia, Lulu Chai, Hanyu Zhang, Zhaohui Sun.
      With the aging population increasing dramatically and the high cost of long-term care (LTC), long-term care insurance (LTCI) has expanded rapidly across the world. This review aims to summarize the status quo, evolution trends, and new frontiers of global LTCI research between 1984 and 2021 through a comprehensive retrospective analysis. A total of 1568 articles retrieved from the Web of Science Core Collection database were systematically analyzed using CiteSpace visualization software (CiteSpace 5.8. R2, developed by Dr. Chaomei Chen at Drexel University (Philadelphia, PA, USA)). The overall characteristics analysis showed that LTCI is an emerging research field in a rapid development stage-nearly 50% of articles were published in the past five years. The most productive LTCI research institutions and authors are located primarily in Japan and the USA. A rigorous analysis based on a dual perspective of references and keywords was applied to reveal that common LTCI hot topics include disability in the elderly, LTC financing, demand for and supply of LTCI, and LTCI systems. In addition, LTCI research trends have shifted from the supply side to the demand side, and from basic studies to practical applications. The new research frontiers are frailty in the elderly, demand for LTCI, and LTCI systems. These findings can provide help and reference for public health practitioners and researchers, as well as help with the sustainable development of LTCI research.

    Application of Telemedicine in COVID-19: A Bibliometric Analysis.
    Xue Lan, Han Yu, Lei Cui.
       Background: Telemedicine as a tool that can reduce potential disease spread and fill a gap in healthcare has been increasingly applied during the COVID-19 pandemic. Many studies have summarized telemedicine's technologies or the diseases' applications. However, these studies were reviewed separately. There is a lack of a comprehensive overview of the telemedicine technologies, application areas, and medical service types.
    Objective: We aimed to investigate the research direction of telemedicine at COVID-19 and to clarify what kind of telemedicine technology is used in what diseases, and what medical services are provided by telemedicine.
    Methods: Publications addressing telemedicine in COVID-19 were retrieved from the PubMed database. To extract bibliographic information and do a bi-clustering analysis, we used Bicomb and gCLUTO. The co-occurrence networks of diseases, technology, and healthcare services were then constructed and shown using R-studio and the Gephi tool.
    Results: We retrieved 5,224 research papers on telemedicine at COVID-19 distributed among 1460 journals. Most articles were published in the Journal of Medical Internet Research (166/5,224, 3.18%). The United States published the most articles on telemedicine. The research clusters comprised 6 clusters, which refer to mental health, mhealth, cross-infection control, and self-management of diseases. The network analysis revealed a triple relation with diseases, technologies, and health care services with 303 nodes and 5,664 edges. The entity "delivery of health care" was the node with the highest betweenness centrality at 6,787.79, followed by "remote consultation" (4,395.76) and "infection control" (3,700.50).
    Conclusions: The results of this study highlight widely use of telemedicine during COVID-19. Most studies relate to the delivery of health care and mental health services. Technologies were primarily via mobile devices to deliver health care, remote consultation, control infection, and contact tracing. The study assists researchers in comprehending the knowledge structure in this sector, enabling them to discover critical topics and choose the best match for their survey work.

    Trends of social networks in the American College of Surgeons Clinical Congress and the Congreso Nacional de Cirugía. Analysis of the #ACSCC20 and #CNCirugia2020.
    Sergi Sanchez-Cordero, Salvador Morales-Conde, Raquel Sánchez Santos, Inés Rubio Perez, Roser Farré Font, Jose Luis Ramos Rodriguez, José M Balibrea Del Castillo, Julio Mayol.
       AIM: The objective of this study is to analyze the impact of the congresses of the American College of Surgeons (ACSCC2020) and the National Surgery Congress of the Spanish Association of Surgeons (CNC2020) in virtual format due to the SARS-CoV2 pandemic according to the fingerprint.
    MATERIAL AND METHODS: The Twitter hashtags # ACSCC20 and # CNCirugia2020 were studied to determine tweets, retweets, users and impressions. The data on the accounts with the greatest influence and the historical evolution of the congresses between 2015 and 2020 were analyzed. We used the symplur software to collect and analyze the data.
    RESULTS: Between 2015 and 2017 there was a consistent increase in the number of tweets, participants and impressions. Between 2018 and 2020, the ACS maintains the number of impressions with the fewest number of tweets. However, the CNC continues to grow and achieves its best metrics in 2020. We found statistically significant differences between the most prolific accounts of the ACSCC versus the CNC (p < 0.002) but there are no differences between the 10 most influential accounts (p = 0,19) or the accounts with the highest number of impressions (p = 0.450) CONCLUSIONS: Virtual congresses generate a global impact through the use of Twitter for the dissemination of knowledge. In the present 2020, the growth of the impact on social networks has been proportionally greater in the CNC than in the ACSCC. However, the ACS virtual congress generated the greatest impact on social networks measured by the number of users, tweets and impressions between 2015 and 2020.

    Human mobility behavior in COVID-19: A systematic literature review and bibliometric analysis.
    Francisco Benita.
      This article maps the scientific literature in human mobility behavior in the context of the current pandemic. Through bibliometrics, we analyze the content of published scientific studies indexed on the Web of Science and Scopus during 2020. This enables us the detection of current hotspots and future directions of research. After a co-occurrence of keywords and evidence map analysis, four themes are identified, namely, Land Transport - Operations, Land Transport - Traffic Demand, Air Transport and Environment. We show how air transportation- and environmental-related studies tend to be more mature research whereas the understanding of changes in travel behavior (e.g., telecommuting, preventive measures or health protection behavior) tends to be immature. By using a topic modeling approach, we identify multiple sub-themes within each theme. Our framework adopts a smart literature review approach that can be constantly updated, enabling an analysis of many articles, with little investment of the researcher's time, but also provides high degree of transparency and replicability. We also put forth a research agenda that can help inform and shape transport policy and practice responses to COVID-19.

    Identifying Topics and Evolutionary Trends of Literature on Brain Metastases Using Latent Dirichlet Allocation.
    Jiarong Chen, Matt Williams, Yanming Huang, Shijing Si.
      Research on brain metastases kept innovating. We aimed to illustrate what topics the research focused on and how it varied in different periods of all the studies on brain metastases with topic modelling. We used the latent Dirichlet allocation model to analyse the titles and abstracts of 50,176 articles on brain metastases retrieved from Web of Science, Embase and MEDLINE. We further stratified the articles to find out the topic trends of different periods. Our study identified that a rising number of studies on brain metastases were published in recent decades at a higher rate than all cancer articles. Overall, the major themes focused on treatment and histopathology. Radiotherapy took over the first and third places in the top 20 topics. Since the 2010's, increasing attention concerned about gene mutations. Targeted therapy was a popular topic of brain metastases research after 2020.

    A Bibliometric Analysis of Triptolide and the Recent Advances in Treating Non-Small Cell Lung Cancer.
    Quancheng Yang, Xuejia Zhai, Yi Lv.
      In recent decades, natural products derived from plants and their derivatives have attracted great interest in the field of disease treatment. Triptolide is a tricyclic diterpene extracted from Tripterygium wilfordii, a traditional Chinese medicine, which has shown excellent therapeutic potential in the fields of immune inflammation and cancer treatment. In this study, 1,106 Web-of-Science-indexed manuscripts and 1,160 Chinese-National-Knowledge-Infrastructure-indexed manuscripts regarding triptolide published between 2011 and 2021 were analyzed, mapping the co-occurrence networks of keywords and clusters using CiteSpace software. The research frontier and development trend were determined by keyword frequency and cluster analysis, which can be used to predict the future research development of triptolide. Non-small cell lung cancer (NSCLC) is most common in lung cancer patients, accounting for about 80% of all lung cancer patients. New evidence suggests that triptolide effectively inhibits the development and metastasis of NSCLC by the induction of apoptosis, reversion of EMT, and regulation of gene expression. Specifically, it acts on NF-κB, MAPKs, P53, Wnt/β-catenin, and microRNAs (miRNAs), signaling pathways and molecular mechanisms. Consequently, this article reviews the research progress of the anti-NSCLC effect of triptolide. In addition, attenuated studies on triptolide and the potential of tumor immunotherapy are also discussed.

    Trends and Insights from Transportation Congestion Pricing Policy Research: A Bibliometric Analysis.
    Bhavna Singichetti, Adam Dodd, Jamie L Conklin, Kristen Hassmiller Lich, Nasim S Sabounchi, Rebecca B Naumann.
      Toll-based congestion pricing (CP) policies are increasingly implemented globally for alleviating road traffic congestion. Several interconnected factors affecting or induced by CP implementation include air quality/emissions, travel time, and road user safety. We sought to examine and characterize research output and patterns across several domains (e.g., health, policy acceptability) surrounding toll-based CP policies, in order to identify where research has focused and where gaps exist. We conducted a structured review and identified 2333 relevant publications, using semi-supervised and machine learning strategies combined with manual review. Annual publication counts peaked in 2015 (n = 122). Themes identified from title and abstract terms included policy implementation characteristics, advanced transportation modeling methods and approaches, and public perception and acceptability. Authorship networks indicated a lack of interdisciplinary research. Country analyses identified the US, China, and the UK as the most frequently represented countries, and underrepresentation from low-income countries. Findings indicate that research focused on specific road user types (e.g., pedestrians) and safety impacts, and equity considerations were relatively sparse compared to other topics (e.g., policy economics, public perception). Additional research on these critical topics is necessary to ensure that such policies are designed to promote positive and equitable effects on road user health and safety.

    Global pattern and drivers of water scarcity research: a combined bibliometric and geographic detector study.
    Siao Sun, Xiangyi Zheng, Xingcai Liu, Zhenbo Wang, Longwu Liang.
      Water scarcity, which refers to a deficit of freshwater resources availability in meeting anthropogenic and environmental water needs, is nowadays a growing concern in many countries around the world. Because water scarcity is often poor management induced, research is critical to advance knowledge and provide technical and policy support for water scarcity adaptation and solutions. Here, we address global water scarcity research pattern and underlying drivers, using the bibliometric analysis combined with geographic detector. The results indicate that water scarcity research exhibits great temporal and spatial variations. Predominant factors that control the numbers of water scarcity publications are gross domestic products (GDP) and population, which altogether explain 30-52% of the variance of the number of publications in different countries. Water scarcity research is biased in a few populated and affluent countries. Other factors, including physical water scarcity, research and development expenditure, and governance indicators can also be linked to water scarcity research. Keywords mining reveals that hotspots of research domains on causes, approaches, types, and effects of water scarcity show continental difference. The results have policy implications for guiding future water scarcity research. Research in developing countries suffering from physical and economic water scarcity should be enhanced to improve adaptive capacity and reduce vulnerability to water scarcity.

    To Have the Best Interest at Heart: Analyzing the Match Between Laypersons' Interests and Publication Activity in Psychology.
    Mark Jonas, André Bittermann, Anita Chasiotis, Tom Rosman.
      There is a growing public interest in science and, by extension, in psychology, and human behavior. Yet, detailed investigations on whether academic psychological research activity matches lay interests are still scarce. In addition, while lay-friendly communication of research findings becomes continually more important, it is unclear which subfields of psychological research are particularly interesting to laypeople. To address these research gaps, we carried out an explorative study of psychological literature included in two large reference databases, one with a German (PSYNDEX) and one with an international (PsycInfo) scope. The years of 2018-2020 were scanned for articles belonging to one of 20 topic areas assessed as most interesting by lay participants in a previous study. We determined and compared the share of empirical research and research syntheses for each topic area and database and computed rank correlations between lay interest and academic publication volume. Results suggest a positive relationship between lay interest and academic publication activity specifically for research syntheses. Additionally, topic areas associated with clinical psychology offered a large share of research syntheses, while other topic areas such as "Psychodynamics" or "Industrial & Organizational Psychology" encompassed a smaller share of syntheses. Finally, we outline perspectives for long-term monitoring of psychology-related lay interests. Thus, the present study connects academic activity with the public interest in psychology by identifying and quantifying research syntheses for topics garnering the most lay interest.

    Reporting of Statistical Inference in Abstracts of Major Cancer Journals, 1990 to 2020.
    Andreas Stang, Börge Schmidt.
       Importance: Since the 1990s, reporting guidelines have developed that uniformly require authors to report a measure of precision (confidence intervals [CIs]) in addition to effect size.
    Objective: To investigate the time trend of statistical inference and statistical reporting style in abstracts of major cancer journals.
    Design, Setting, and Participants: This cross-sectional study reviewed all abstracts published between January 1, 1990, and December 31, 2020, in 10 high-ranking cancer journals (Lancet Oncology, Journal of Clinical Oncology, Cancer Discovery, Cancer Cell, JAMA Oncology, Annals of Oncology, Molecular Cancer, Journal of Thoracic Oncology, Journal of the National Cancer Institute, and Trends in Cancer) using a previously validated computerized algorithm to search the PubMed database. For the time trend analyses, 2 journals with only a few years of existence (JAMA Oncology and Trends in Cancer) were excluded.
    Exposures: Calendar year, journal, and type of abstract (randomized clinical trial or other).
    Main Outcomes and Measures: Proportions of abstracts containing CIs, P values without CIs, and qualitative expressions of statistical significance only were compared over time among journals.
    Results: Overall, 24 034 of 42 509 abstracts (56.5%) contained statistical inference. Reporting of CIs increased over time in 5 of 8 journals. From 2016 to 2020, the most prevailing statistical reporting style was the presentation of CIs (3070 of 4895 [62.7%]). However, the proportion of abstracts reporting statistical inference based solely on the terms significant or nonsignificant was still 1195 of 4895 (24.4%) during this period and was most prevalent among basic science-oriented cancer journals (eg, 63 of 66 [95.5%] in Cancer Cell). A higher prevalence of CI reporting was associated with reporting of results from randomized clinical trials and the requirement to report according to guidelines (eg, 522 of 574 [90.9%] in Lancet Oncology).
    Conclusions and Relevance: These findings suggest that the reporting style of statistical inference in abstracts of major cancer journals has improved over time. A requirement in journals' instructions for authors to present statistical inference in accordance with reporting guidelines and the implementation of these guidelines in submitted manuscripts on the part of journal editors may improve reporting.

    The Association of Pediatric Critical Care Medicine Training Programs with Research Publication Productivity and Employment Outcomes of Their Graduates.
    Sonali Basu, Robin Horak, Murray M Pollack.
      Our objective was to associate characteristics of pediatric critical care medicine (PCCM) fellowship training programs with career outcomes of PCCM physicians, including research publication productivity and employment characteristics. This is a descriptive study using publicly available data from 2557 PCCM physicians from the National Provider Index registry. We analyzed data on a systematic sample of 690 PCCM physicians representing 62 fellowship programs. There was substantial diversity in the characteristics of fellowship training programs in terms of fellowship size, intensive care unit (ICU) bed numbers, age of program, location, research rank of affiliated medical school, and academic metrics based on publication productivity of their graduates standardized over time. The clinical and academic attributes of fellowship training programs were associated with publication success and characteristics of their graduates' employment hospital. Programs with greater publication rate per graduate had more ICU beds and were associated with higher ranked medical schools. At the physician level, training program attributes including larger size, older program, and higher academic metrics were associated with graduates with greater publication productivity. There were varied characteristics of current employment hospitals, with graduates from larger, more academic fellowship training programs more likely to work in larger pediatric intensive care units (24 [interquartile range, IQR: 16-35] vs. 19 [IQR: 12-24] beds; p  < 0.001), freestanding children's hospitals (52.6 vs. 26.3%; p  < 0.001), hospitals with fellowship programs (57.3 vs. 40.3%; p  = 0.01), and higher affiliated medical school research ranks (35.5 [IQR: 14-72] vs. 62 [IQR: 32, unranked]; p  < 0.001). Large programs with higher academic metrics train physicians with greater publication success (H index 3 [IQR: 1-7] vs. 2 [IQR: 0-6]; p  < 0.001) and greater likelihood of working in large academic centers. These associations may guide prospective trainees as they choose training programs that may foster their career values.

    Women are Credited Less in Science than are Men.
    Matthew B Ross, Britta M Glennon, Raviv Murciano-Goroff, Enrico G Berkes, Bruce A Weinberg, Julia I Lane.
      There is a well-documented gap in the observed number of scientific works produced by women and men in science, with clear consequences for the retention and promotion of women in science1. The gap might be a result of productivity differences2-5, or it might be due to women's contributions not being acknowledged6,7. This paper finds that at least part of this gap is due to the latter: women in research teams are significantly less likely to be credited with authorship than are men. The findings are consistent across three very different sources of data. Analysis of the first source - large scale administrative data on research teams, team scientific output, and attribution of credit - show that women are significantly less likely to be named on any given article or patent produced by their team relative to their peers. The gender gap in attribution is found across almost all scientific fields and career stages. The second source - an extensive survey of authors - similarly shows that women's scientific contributions are systematically less likely to be recognized. The third source - qualitative responses - suggests that the reason is that their work is often not known, not appreciated, or ignored. At least some of the observed gender gap in scientific output may not be due to differences in scientific contribution, but to differences in attribution.

    Neonicotinoids: A critical assessment of the global research landscape of the most extensively used insecticide.
    Doris Klingelhöfer, Markus Braun, Dörthe Brüggmann, David A Groneberg.
      The broad-spectrum insecticides in the neonicotinoid group are the most widely used worldwide because of their widely recognized advantages in the mode of action. Therefore, their use is growing on a large scale and, moreover, is often used preventively without considering the ecological impact. Studies demonstrated harmful effects on non-target organisms, which in turn negatively impact biodiversity and thus food production. The dramatic decline of honey bee colonies, for example, could be linked to the use of neonicotinoids. Ecologically sustainable solutions to this conflict must be focused by scientific research. The question arose whether the global research efforts meet these requirements on a global scale. Therefore, this review article aimed to analyze the global research landscape on neonicotinoids under ecological, economic, and temporal aspects. To this end, key players and incentives for investigations in this research field are identified. The increase in publications over time is significant and shows a dynamic citation pattern. It indicates a comparatively high interest in current research, with ecological issues becoming more and more the focus of international research. It has been shown that national publication performance and funding are in line with global market interests, with the most publishing country being China. In addition, the elevated status quo of the scientific infrastructure in high-economy countries and their willingness to support research can be linked to national research output. Lower economies are sparsely involved in published studies. The research performance accumulates with a high North-South divide. Therefore, future research projects must have a sustainable focus and take regional requirements worldwide into account. This requires greater involvement of developing countries as the most economically dependent regions with enormously increasing consumption rates. Solutions must be found to ensure sustainable food production against a backdrop of already declining biodiversity due to the large-scale use of neonicotinoids.

    Self-referencing authorships behind the ICNIRP 2020 radiation protection guidelines.
    Else K Nordhagen, Einar Flydal.
      In March 2020, ICNIRP (the International Commission for Non-Ionizing Radiation Protection) published a set of guidelines for limiting exposure to electromagnetic fields (100 kHz to 300 GHz). ICNIRP claims this publication's view on EMF and health, a view usually termed "the thermal-only paradigm", is consistent with current scientific understanding. We investigated the literature referenced in ICNIRP 2020 to assess if the variation in authors and research groups behind it meets the fundamental requirement of constituting a broad scientific base and thus a view consistent with current scientific understanding, a requirement that such an important set of guidelines is expected to satisfy. To assess if this requirement has been met, we investigated the span of authors and research groups of the referenced literature of the ICNIRP 2020 Guidelines and annexes. Our analysis shows that ICNIRP 2020 itself, and in practice all its referenced supporting literature stem from a network of co-authors with just 17 researchers at its core, most of them affiliated with ICNIRP and/or the IEEE, and some of them being ICNIRP 2020 authors themselves. Moreover, literature reviews presented by ICNIRP 2020 as being from independent committees, are in fact products of this same informal network of collaborating authors, all committees having ICNIRP 2020 authors as members. This shows that the ICNIRP 2020 Guidelines fail to meet fundamental scientific quality requirements and are therefore not suited as the basis on which to set RF EMF exposure limits for the protection of human health. With its thermal-only view, ICNIRP contrasts with the majority of research findings, and would therefore need a particularly solid scientific foundation. Our analysis demonstrates the contrary to be the case. Hence, the ICNIRP 2020 Guidelines cannot offer a basis for good governance.

    Epilepsy research in Africa: A scoping review by the ILAE Pediatric Commission Research Advocacy Task Force.
    Pauline Samia, Jane Hassell, Jessica Hudson, Azim Ahmed, Jasmit Shah, Charles Hammond, Edward Kija, Stéphane Auvin, Jo Wilmshurst.
       OBJECTIVE: Despite the high prevalence of epilepsy in Africa, evaluation of epilepsy research trends on the continent is lacking. Without establishing effective research, improvement in care for people with epilepsy cannot be effectively strategized or targeted.
    METHODS: A scoping review of the peer-reviewed literature on epilepsy from Africa (1989-2019) was conducted. The aim was to understand from this what areas are well researched versus underresearched based on published epilepsy topics.
    RESULTS: A total of 1227 publications were identified and assessed. A significant increase in publications occurred over the 30 years assessed. African author leadership was evident in most reports. Nine countries had >50 publications identified; the remaining 45 countries had <50 or no publications. Research studies were typically of lower quality (case series and observational studies). Research themes were more focused on clinical epilepsy (descriptive observational studies) and social aspects (qualitative surveys). However, there were a number of unique and strong themes, specifically for neurocysticercosis and nodding syndrome, where strong research collaborations were evident, basic science understandings were explored, and interventional models were established.
    SIGNIFICANCE: Despite Africa being the continent with the most countries, it is lacking in the quantity, quality, and for some areas, relevance of research on epilepsy. Targeted approaches are needed to upskill the strength of research undertaken with more basic science, interventional, and randomized controlled studies. Themes of research need to promote those with unique African content but also to align with current international research areas that have impact on care delivery, such as epilepsy surgery and epilepsy genetics. For this to be possible, it is important to strengthen research hubs with collaborations that empower Africa to own its epilepsy research journey.

    Gender inequities in medical research funding is driving an exodus of women from Australian STEMM academia.
    Jessica G Borger, Louise E Purton.
      Universally, women are underrepresented in senior academic leadership in Science Technology Engineering Maths and Medicine (STEMM). Successful funding outcomes are a critical point in career progression, to continue both a scientist's research but also for their retention within the STEMM workforce. A common explanation for the lower success rate of women in securing funding is that fewer women apply for funding. However, this does not adequately explain the gender inequities in funding outcomes, both in terms of fewer funded applications and also reduced funding awarded per grant, resulting in less overall success. Gendered funding outcomes occur within academic institutions and peak funding bodies due to historical, systemic conscious and unconscious biases during peer review. As a cumulative bias over a woman's research career, this results in women being underrepresented in STEMM and the loss of their contributions to medical research, reducing innovation through lack of diverse workforces.

    Analysis of Domestic and International Green Infrastructure Research Trends from the ESG Perspective in South Korea.
    Eunjoung Lee, Gunwoo Kim.
      Government-level ESG (environmental, social, and governance) institutionalization and active ESG activation in the private sector are being discussed for the first time this year in Korea, spurred by increased national interest since the COVID-19 pandemic crisis and the declaration of a carbon-neutral society by 2050, and ESG discussion in many fields is spreading rapidly. In addition, global awareness of the crisis caused by environmental pollution and natural disasters has highlighted the importance of green infrastructure (GI) as a new conceptual alternative to improve public value. Based on sustainability, which is a common goal of ESG and green infrastructure, this study aimed to examine the research targets and techniques of green infrastructure from the perspective of ESG. This study selected and analyzed 98 domestic and international academic journal papers published over the past 10 years in the Web of Science academic journal database literature collection. Focusing on the research subjects, the focus on green infrastructure, and research keywords, we examined the aspects of the green infrastructure plan that have been focused on from the ESG perspective and compared domestic and international research trends. In addition, implications for how each research topic is connected to the concept of ESG according to its function and purpose were derived. By examining the domestic and international research trends of green infrastructure from the ESG perspective, we identified the need for a wider range of research on the diversity and relationship between humans and the ecological environment; policies and systems; and technical research that does not focus only on a specific field. In this regard, we intend to increase the contribution to ESG management in the public sector through the establishment of green infrastructure plans and policies in the future, as they account for a large portion of public capital.

    Discovering Interdisciplinary Research Based on Neural Networks.
    Tao He, Wei Fu, Jianqiao Xu, Zhihong Zhang, Jiuxing Zhou, Ying Yin, Zhenjie Xie.
      Interdisciplinary research promotes the emergence of scientific innovation. Researchers want to find interdisciplinary research in their research field. However, the number of scientific papers published today is increasing, and completing this task by hand is time-consuming and laborious. A neural network is a machine learning model that simulates the connection mode of neurons in the human brain. It is an important application of bionics in the artificial intelligence field. This paper proposes an approach to discovering interdisciplinary research automatically. The method generates an IRD-BERT neural network model for discovering interdisciplinary research based on the pre-trained model BERT. IRD-BERT is used to simulate the domain knowledge of experts, and author keywords can be projected into vector space by this model. According to the keyword distribution in the vector space, keywords with semantic anomalies can be identified. Papers that use these author keywords are likely to be interdisciplinary research. This method is applied to discover interdisciplinary research in the deep learning research field, and its performance is better than that of similar methods.

    Differences in Global Scientific Production Between New mRNA and Conventional Vaccines Against COVID-19.
    Miguel Angel Ruiz-Fresneda, Rafael Ruiz-Pérez, Carlos Ruiz-Fresneda, Evaristo Jiménez-Contreras.
      The search for effective vaccines to stop the COVID-19 pandemic has led to an unprecedented amount of global scientific production and activity. This study aimed to analyze global scientific production on the different vaccine types (mRNA and conventional) that were validated for COVID-19 during the years 2020-2021. The scientific production generated on COVID-19 vaccines during the period 2020-2021 totaled the enormous amount of 20,459 studies published. New mRNA vaccines clearly showed higher production levels than conventional vaccines (viral and inactivated vectors), with 786 and 350 studies, respectively. The USA is the undisputed leader in the global production on COVID-19 vaccines, with Israel and Italy also playing an important role. Among the journals publishing works in this field, the New England Journal of Medicine, the British Medical Journal, and Vaccines stand out from the rest as the most important. The keyword 'immunogenicity' and its derivatives have been more researched for the new mRNA vaccines, while thrombosis has been more studied for conventional vaccines. The massive scientific production generated on COVID-19 vaccines in only two years has shown the enormous gravity of the pandemic and the extreme urgency to find a solution. This high scientific production and the main keywords found for the mRNA vaccines indicate the great potential that these vaccines have against COVID-19 and future infectious diseases. Moreover, this study provides valuable information for guiding future research lines and promoting international collaboration for an effective solution.
