    David Constantinescu, Dylan Luxenburg, Moses Isaac Markowitz, Rami Hisham Helmi Mahmoud, Michele D'Apuzzo.
      Background: Bibliometric analysis is a useful tool for measuring the scholarly impact of a topic. To date, there is no such review analyzing the characteristics and trends of publications focused on revision total hip arthroplasty (rTHA). The purpose of this study is to use bibliometric analysis to comprehensively analyze the 50 most cited articles in rTHA research.Methods: This is a cross-sectional study that used the ISI Web of Knowledge database to identify articles published before September 2021. Articles were sorted in descending order by number of citations and those with a focus of rTHA were identified. Of these, the top 50 most cited articles were carried forward for evaluation.
    Results: The 2000s (50%) and the 1990s (32%) had the greatest volume of contribution. 9 of the top 10 most cited articles were published in the 2000s. The highest impact article had 4702 citations. The level of evidence (LOE) published with the greatest frequency was LOE II (40%) followed by LOE III and LOE IV both recording 24%. The Journal of Bone and Joint Surgery-American Volume had the greatest productivity (46%) followed by The Journal of Bone and Joint Surgery-British Volume (18%). The United States was the country with the highest number of contributions to this list with 56% followed by England (12%), and Sweden and Canada both with 8%.
    Conclusion: The most impactful articles focusing on rTHA research were comprehensively and objectively analyzed. The most common article type was clinical outcomes (46%) followed by natural history/epidemiology (24%) and surgical technique (16%). While this topic is highly studied with significant level of evidence to support the studies, there is a lack of influential research regarding imaging and clinical guidelines. This analysis can be used by researchers to develop further discussions and build research questions.

    Twenty-five years of education and information technologies: Insights from a topic modeling based bibliometric analysis.
    Ozcan Ozyurt, Ahmet Ayaz.
      Education and Information Technologies (EAIT) has been a leading journal in education & educational research since 1996. To celebrate its 25th anniversary and provide a comprehensive overview of the field, a topic modeling-based bibliometric analysis was conducted on the articles published in this journal. The study is constructed upon two methods, bibliometric analysis, and topic modeling. The study aims to find out the trends in publications and citations, prominent countries, affiliations and the status of authors, the prominent topics, and the thematic characteristics of these topics, as well as research interests and trends. The results show that the articles are grouped under the 21 topics. The top five most studied of them have been determined as "Technology acceptance", "Social networkbased learning", "Teacher education", "Satisfaction of e-learning" and "E-learning". Finally, the acceleration results of each topic within itself and compared to other topics show that the most accelerated topic is "Gamification", while the most accelerated topic compared to other topics has been determined as "Technology acceptance". The general results of the study shed light on future studies in terms of determining the research interests and trends of publications in the field of educational technologies, EAIT.

    Virtual Laboratories- A historical review and bibliometric analysis of the past three decades.
    Raghu Raman, Krishnashree Achuthan, Vinith Kumar Nair, Prema Nedungadi.
      Online and virtual teaching-learning has been a panacea that most educational institutions adopted from the dire need created by COVID-19. We provide a comprehensive bibliometric study of 9523 publications on virtual laboratories in higher education covering the years 1991 to 2021. Influential bibliometrics such as publications and citations, productive countries, contributing institutions, funders, journals, authors, and bibliographic couplings were studied using the Scientific Procedures and Rationales for Systematic Literature Reviews (SPAR-4-SLR) protocol. A new metric to complement citations called Field Weighted Citation Impact was introduced that considers the differences in research behavior across disciplines. Findings show that 72% of the research work was published between 2011-and 2021, most likely due to digitalization, with the highest number of publications in 2020-2021 highlighting the impact of the pandemic. Top contributing institutions were from the developed economies of Spain, Germany, and the United States. The citation impact from publications with international co-authors is the highest, highlighting the importance of co-authoring papers with different countries. For the first time, Altmetrics in the context of virtual labs were studied though a very low correlation was observed between citations and Altmetrics Attention Score. Still, the overall percentage of publications with attention showed linear growth. Our work also highlights that virtual laboratory could play a significant role in achieving the United Nations Sustainable Development Goals, specifically SDG4-Quality Education, which largely remains under-addressed.

    Erhan Kaya, Hüseyin Üçer.
      INTRODUCTION: Tularemia disease attracts attention as an important contagious zoonosis that has increased its impact in recent years. The aim of the study is to analyze the publications on tularemia between 1980 and 2020.METHODS: We performed literature retrieval in the Web of Science (WoS) on 22 September 2021. Search terms were "Francisella tularensis" and "Tularemia" in the article title for the period between January 1980 and December 2020. We determined the number of articles, keywords, countries, authors, and institutions for each publication. We visualized the data with the VOS viewer tool.
    RESULTS: After all inclusion and exclusion criteria were applied finally, 1688 articles were analyzed. The number of articles has increased in recent years. The three most productive countries in tularemia were the USA (777 articles 46.03%), Sweden (113 articles 6.69%), and Turkey (95 articles, 5.63%). Most of the articles were from the journal of Infection and Immunity (II), Plos one, Journal of Clinical Microbiology (JCM), Emerging Infectious Diseases (EID), and Vaccine. Sjostedt A. and Umea University-Sweden were the most influential author and institution.
    CONCLUSIONS: Productivity trend has been shown to increase in tularemia. High-income countries had a great influence on the literature in the field. Publications from the USA were in a high percentage among all articles. Related work may lead to the future direction of this dossier in the next years.

    Alyssa M Thompson, Justine Seivright, Jennifer L Hsiao, Vivian Y Shi.
      Atopic dermatitis (AD) affects up to 20% of children worldwide. We identified the top 50 cited AD articles in the last seven decades and examined their characteristics. The majority were discussing the pathogenesis of AD and have paved the way for discovering targeted immunomodulatory treatments. A lack of geographic diversity was noted, thus encouraging more countries to be involved in AD research can further progress the future of AD management.

    The Last Decade Publications on Diabetic Peripheral Neuropathic Pain: A Bibliometric Analysis.
    Shu-Hao Du, Yi-Li Zheng, Yong-Hui Zhang, Ming-Wen Wang, Xue-Qiang Wang.
      Background: Diabetic peripheral neuropathic pain (DPNP) is a usual complication of diabetes with a high incidence and mortality. Many diabetes-related studies have been published in various journals. However, bibliometrics and visual analyses in the domain of DPNP research are still lacking. The study aimed to offer a visual method to observe the systematic overview of global research in this field from 2011 to 2021.Methods: The publications from the Science Citation Index Expanded in Web of Science (WOS) in the past 11 years (from 2011 to 2021) were collected and sorted out, and those related to DPNP were extracted and analyzed. The article language was limited in English. Then, CiteSpace V was used for the bibliometric analysis of the extracted literature.
    Results: A total of 1,422 articles met the inclusion criteria. A continuous but unstable growth in the amounts of papers published on DPNP was observed over the last 11 years. The subject sort of the 1,422 papers mainly concentrates on Endocrinology Metabolism, Clinical neurology and Neurosciences from the WOS. According to the research contribution in the field of DPNP, the United States occupies a leading position, with the highest amounts of publications, citations, open access, and the H- index.
    Conclusion: This study provides a visual analysis method for the trend of DPNP, and offers some hidden serviceable information that may define new directions for future research.

    Yanhao Liu, Yan Xu, Xi Cheng, Yaru Lin, Shu Jiang, Haiming Yu, Zhen Zhang, Linlin Lu, Xiaotao Zhang.
      In this study, a bibliometric analysis was carried out to identify the most influential clinical studies and research trends on anti-programmed cell death 1/programmed cell death 1 ligand 1 (anti-PD1/PDL1) immunotherapy. On January 1, 2022, we used Web of Science to identify the 100 most frequently cited papers on clinical studies investigating anti-PD1/PDL1 immunotherapy, and extracted the following data: publication year, source title, country/region, institution, and the total number of citations. The research design and area were classified independently by the authors. Subsequently, we carried out a bibliometric analysis to determine the trends and identify the major journals on anti-PD1/PDL1 immunotherapy. The authors analyzed the current research hotspots based on papers published in major journals from 2020 to 2021. These 100 papers were cited a total of 138,840 times, and the median number of citations was 899.5 (range: 341-7,983). "Safety, activity, and immune correlates of anti-PD-1 antibody in cancer" by Topalian et al. had the highest number of citations (7,983 times). New England Journal of Medicine had the highest number of top-cited papers (40 papers), average citations per paper (1,558.3 citations), and rate of top-cited papers (65.6%). Authors from the USA contributed most of the papers (76 papers). Lung cancer (30 papers, 46,422 citations) and melanoma (20 papers, 30,881 citations) were the most cited research areas. In summary, anti-PD1/PDL1 has become standard treatment for various cancer, while adjuvant anti-PD1/PDL1 therapy is currently a research hotspot. New England Journal of Medicine was identified as the most influential journal in this area. Non-small cell lung cancer and melanoma are the most well-studied cancers, while nivolumab and pembrolizumab are the most commonly investigated anti-PD1/PDL1 antibodies. Further studies are warranted to identify effective predictive biomarkers or models, clarify the molecular mechanism of combined therapy, and establish optimal therapeutic strategies. This study may assist researchers in obtaining a comprehensive impression of the landscape and current trends in anti-PD1/PDL1 immunotherapy and gain inspiration to conduct further studies.

    Kaiwen Wu, Ye Liu, Lei Liu, Yunlan Peng, Honglin Pang, Xiaobin Sun, Demeng Xia.
      Background: Pancreatic cancer (PC) is a serious disease with high mortality. The tumor microenvironment plays a key role in the occurrence and development of PC. The purpose of this study is to analyze trends by year, country, institution, journal, reference and keyword in publications on the PC microenvironment and to predict future research hotspots.Methods: The Web of Science Core Collection was used to search for publications. We analyzed the contributions of various countries/regions, institutes, and authors and identified research hotspots and promising future trends using the CiteSpace and VOSviewer programs. We also summarized relevant completed clinical trials.
    Results: A total of 2,155 papers on the PC microenvironment published between 2011 and 2021 were included in the study. The number of publications has increased every year. The average number of citations per article was 32.69. The USA had the most publications, followed by China, and a total of 50 influential articles were identified through co-citation analysis. Clustering analysis revealed two clusters of keywords: basic research and clinical application. The co-occurrence cluster analysis showed glutamine metabolism, carcinoma-associated fibroblasts, oxidative phosphorylation as the highly concerned research topics of basic research in recently. The three latest hot topics in clinical application are liposomes, endoscopic ultrasound and photodynamic therapy.
    Conclusion: The number of publications and research interest have generally increased, and the USA has made prominent contributions to the study of the tumor microenvironment of PC. The current research hotspots mainly focus on energy metabolism in the hypoxic tumor microenvironment, cancer associated fibroblasts in regulating the tumor microenvironment, accurate diagnosis, drug delivery and new treatments.

    Research trends and hotspots of aquatic biofilms in freshwater environment during the last three decades: a critical review and bibliometric analysis.
    Zhirui Qin, Zhenhua Zhao, Liling Xia, Okugbe Ebiotubo Ohore.
      Freshwater periphytic biofilms (FPBs), existing widely in various aquatic environments, have attracted extensive attention for many years. In the present study, a bibliometric analysis based on Web of Science Core Collection (WoSCC) was used to understand the research progress, trends, and hot topics of FPBs qualitatively and quantitatively. The results indicated that publications on FPBs have increased from 1991 to 2020 rapidly, and researchers have focused more on the areas of environmental sciences, microbiology, and marine freshwater biology. The most influential countries were mainly the USA, Spain, France, and Germany. Cooperation network analysis reflected that the USA and its affiliated institutions played crucial roles in the research of FPB cooperation, but the collaboration between core author groups still fell short. Based on the analysis of top 20 high-cited FPB documents over the last 30 years, research hotspots mainly included micro-observation and assembly mechanisms of FPBs; interactions of FPBs and pollutants including heavy metals, antibiotic resistance genes, pathogens, organic pollutants, and nanoparticles; and the role of FPBs for biogeochemical cycling, especially nitrogen cycling. Additionally, future research directions were proposed. Overall, this study provides a comprehensive and systematic overview of FPBs, which is useful for research development and researchers who are interested in this area.

    Institution Origin and Medical School Rank Impact the Citation Frequency and Publication Rate in Orthopaedic Sports Medicine Journals.
    Varag Abed, Dylan S Koolmees, Kareem Elhage, Luke Hessburg, Eric C Makhni.
      Purpose: To examine the trends between various categories of institutions with their respective published orthopaedic sports medicine content and to determine the publication output and citation rate from the 25 highest-ranked medical schools compared with lower-ranked institutions.Methods: Publications between 2015 and 2019 from the American Journal of Sports Medicine, Journal of Bone and Joint Surgery, Journal of Shoulder and Elbow Surgery, Clinical Orthopaedics and Related Research, and Arthroscopy were categorized into university/university affiliated hospitals, non-university affiliated teaching hospitals, public/semi-government research institutes, nonprofit research institutes, private sector institutions, government institutions, and other institutions. Citation rates were collected from PubMed for the first and corresponding author. Similarly, corresponding authors were stratified by U.S. News and World Report 2021 medical school research rankings.
    Results: Of the 12,152 publications identified, 5,044 publications met the inclusion criteria. Nonprofit research institutions garnered the greatest number of citations on average (6.44 based on first author, SD 8.83, n = 214; 6.62 based on corresponding author, SD 9.65, n = 208; P < .001), while university/university-affiliated hospitals produced the majority of published articles (77.0% based on first author, 76.8% based on corresponding author), but had lower average citation rates (4.48 based on first author, SD 6.67, n = 3,886; 4.44 based on corresponding author, SD 6.55, n = 3,873; P < .001). Furthermore, of 1953 medical school publications, the top 25 accounted for 53.1% of publications; however, there was no statistical difference between their citation rates and those of lower rankings (P = 0.47).
    Conclusions: Publications are cited at different rates, depending on their institution of origin. In addition, high-ranking medical schools produce a disproportionately greater output of publications than lower-ranking schools, but there is no statistically significant difference in citation rates on an individual publication basis.
    Clinical Relevance: Knowing how an institution's ranking influences publication and citation rates can help us understand bias in the scientific literature.

    Xinghan Chen, Haitao Xiao, Qiao Zhao, Xuewen Xu, Ying Cen, Dongqin Xiao.
      BACKGROUND: Microneedles composed of arrays of micro-sized needles assembled on a patch, has attracted increasing interest in transdermal drug delivery due to its ease of use and lack of painful responses. Here, a bibliometric analysis was conducted to determine a hotspot and trend of microneedles in the biomedical field.METHODS: All relevant articles about microneedles between 2011 and 2020 were obtained from the databases of Web of Science (WOS) and PubMed of the National Center for Biotechnology Information (NCBI). A series of software such as VOSviwewer, the online bibliometric analysis website, CiteSpace, BICOMB and gCLUTO were used to process the data and get visual images. Processed data and visualized images were conducted to predict the trend of this research field.
    RESULTS: The number of articles published over the last decade had increased rapidly (37 in 2011, 165 in 2020), the Journal of Controlled Release was the most productive journal in microneedle studies. The United States was the most productive country, while the Queens Univ Belfast topped the other institutions. Ryan F Donnelly was the most productive author in the field, while the two most cited articles were published by Gu Zhen group. More importantly, the research trend of microneedles had ranged from physicochemical properties and pharmacokinetics to insulin transdermal injection and vaccine development over the past decade. The four hot spots in microneedle studies, including skin rejuvenation, vaccines, fabrication technology and insulin delivery, were identified. Microneedle vaccination shows promising application prospects, and polymers are considered as the most promising materials for microneedles manufacturing.
    CONCLUSIONS: This study will help researchers understand the hot spots and trends of microneedles in the biomedical field accurately and quickly. Moreover, the exploitation of novel polymeric microneedles will be a solid direction for subsequent research and development of transdermal drug delivery.

    Association between intestinal microbiome and inflammatory bowel disease: Insights from bibliometric analysis.
    Pengfei Xu, Tengteng Lv, Shenghui Dong, Zhihao Cui, Xinyuan Luo, Baolei Jia, Che Ok Jeon, Jie Zhang.
      The gut microbiome is highly linked to inflammatory bowel disease (IBD). A total of 3890 publications related to the two terms from 2000 to 2020 were extracted from the Web of Science Core Collection to study the association from a bibliometric perspective. Publications on this topic have grown rapidly since 2008. The United States and Harvard University are the country and institution with the largest number of publications, respectively. Inflammatory Bowel Diseases is the most productive journal with 211 published articles. The most influential journal in this field is Gut with 13,359 citations. The co-citation analysis of references showed that the IBD-related topics with the highest focus are "gut microbiota," "metagenomics," "bacterial community," "fecal microbiota transplantation," "probiotics," and "colitis-associated colorectal cancer." Keyword cluster and keyword burst analyses showed that "gut microbiota," "metagenomics," and "fecal microbiota transplantation" are currently the most researched topics in the field of IBD. The literature in this field is mainly distributed between alterations of the intestinal microbiota, microbial metabolites, and related host signaling pathways. Probiotic treatment also frequently appears in literature. This bibliometric analysis can guide future research and promote the development of the field of gut microbiome and IBD.

    Drug Therapies for COPD: A Bibliometric Review From 1980 to 2021.
    Gao Zhen, Liu Yingying, Dong Jingcheng.
      Objective: To analyze all chronic obstructive pulmonary disease (COPD) drugs-related articles that were indexed in the Web of Science Core Collection (WOSCC) database until August 28, 2021 using bibliometric analysis, in order to provide a reliable reference for the treatment of COPD. Methods: A comprehensive search was conducted to analyze all COPD drugs-related articles using WOSCC database from inception to August 28, 2021. Abstracts and potentially eligible articles, which were retrieved during literature search, were screened by two reviewers. Besides, the CiteSpace (5.8.R1) software was utilized to analyze the overall structure of the network, the network clusters, the links between clusters, the key nodes or pivot points, and the pathways. Results: A total of 2552 COPD-drugs related articles were retrieved. From the perspective of categorization of published articles based on country, the United States is the country with the largest number of published articles and completed clinical trials, highlighting the important role of this country in the treatment of COPD. However, in terms of the proportion of ongoing clinical trials, China has the highest proportion, suggesting that China will play a more pivotal role in the medication of COPD in the future. From the perspective of cooperation among countries, the cooperation among European countries was closer than that among Asian countries. In the recent three decades, the top 20 institutions, with a particular concentration on the treatment of COPD, were from North America and Europe. The co-citation analysis showed that, among 2,552 articles, 53154 citations were recorded, and the co-citation network indicated that 24 clusters could be achieved. Conclusion: The administration of bronchodilators and pulmonary drug delivery systems, as well as consideration of elderly COPD patients remained the hotspots, while triple therapy and comorbidity of COPD, as well as the prevention and treatment of elderly COPD patients had been frontiers in recent years.

    Does Dedicated Research Time During Residency Predict Resident Academic Productivity and a Future Academic Career?
    Ginikanwa Onyekaba, Jaclyn T Mauch, Carlos Barrero, Joseph A Mellia, Fortunay Diatta, Elizabeth Card, Robyn B Broach, John P Fischer.
      OBJECTIVE: Dedicated research time is a component of certain plastic surgery programs, and yet, there is limited research examining its impact on academic productivity and career outcomes. This study aimed to assess the effect of dedicated research time on the academic productivity of residents and the likelihood of pursuing an academic career.METHODS: We conducted a cross-sectional study that examined bibliometric indices of integrated plastic surgery residency graduates from 2010 to 2020. Academic productivity was determined by the number of peer-reviewed publications and h-index 1 year after residency graduation. Results were analyzed using descriptive statistics, χ2 test, t test, and logistic regression.
    RESULTS: Data on plastic surgery residency graduates were analyzed (N = 490 from 46 programs). The mean numbers of publications and h-index per research track graduate were 26.1 and 8.23, respectively. The mean numbers of publications and h-index per nonresearch track graduate were 15.9 and 5.97, respectively. After controlling for the University of Alabama research ranking through multilinear regression analysis, we found that pursuing dedicated research time was an independent predictor of increased h-index and publication output, although it did not predict an increased likelihood of pursuing an academic career.
    CONCLUSIONS: Participating in dedicated research during residency increases academic productivity, irrespective of the residency program's research rank. Given this finding, offering research years can help support the mission of fostering academic opportunities within plastic surgery.

    Threats to scholarly research integrity arising from paper mills: a rapid scoping review.
    Iván Pérez-Neri, Carlos Pineda, Hugo Sandoval.
      "Paper mills" are unethical outsourcing agencies proficient in fabricating fraudulent manuscripts submitted to scholarly journals. In earlier years, the activity of such companies involved plagiarism, but their processes have gained complexity, involving the fabrication of images and fake results. The objective of this study is to examine the main features of retracted paper mills' articles registered in the Retraction Watch database, from inception to the present, analyzing the number of articles per year, their number of citations, and their authorship network. Eligibility criteria for inclusion: retracted articles in any language due to paper mill activity. Retraction letters, notes, and notices, for exclusion. We collected the associated citations and the journals' impact factors of the retracted papers from Web of Science (Clarivate) and performed a data network analysis using VOSviewer software. This scoping review complies with PRISMA 2020 statement and main extensions. After a thorough analysis of the data, we identified 325 retracted articles due to suspected operations published in 31 journals (with a mean impact factor of 3.1). These retractions have produced 3708 citations. Nearly all retracted papers have come from China. Journal's impact factor lower than 7, life sciences journals, cancer, and molecular biology topics were common among retracted studies. The rapid increase of retractions is highly challenging. Paper mills damage scientific research integrity, exacerbating fraud, plagiarism, fake images, and simulated results. Rheumatologists should be fully aware of this growing phenomenon.

    Evaluation of the National Institutes of Health-Supported Relative Citation Ratio among American Shoulder and Elbow Surgeons Fellowship Faculty: A New Bibliometric Measure of Scientific Influence.
    Suleiman Y Sudah, Robert D Faccone, Patrick J Denard, Mariano E Menendez.
      BACKGROUND: Publication metrics are used to evaluate and compare research productivity amongst academic faculty. However, traditional bibliometrics, such as the H-index and article citation count, are limited by lack of field-normalization and yield inaccurate cross-specialty comparisons. Herein, we evaluate the use of a new field-normalized article-level metric developed by the National Institutes of Health (NIH), known as the relative citation ratio (RCR), amongst American Shoulder and Elbow Surgeons (ASES) fellowship faculty and analyzed physician factors associated with RCR values.METHODS: A retrospective data analysis was performed using the iCite database for all shoulder and elbow surgery fellowship faculty listed on the American Shoulder and Elbow Surgeons (ASES) directory as of November 14, 2021. Mean RCR, weighted RCR, and total publication count were compared by sex, career duration, academic rank, and presence of additional degrees. Mean RCR represents the total number of article citations per year of a publication divided by the average number of citations per year received by NIH-funded papers in the same field; mean RCR serves as a measure of overall research impact. A value of 1.0 is the NIH-funded field-normalized standard. The weighted RCR represents the sum of all article-level RCR scores and is a measure of overall research productivity. Student t-tests were used for two-group analyses whereas the analysis of variance tests (ANOVA) were used for between-group comparisons of three or more subgroups.
    RESULTS: A total of 145 ASES fellowship faculty members from 33 fellowship programs were included in the analysis. Overall, ASES fellowship faculty produced highly impactful research with a median RCR of 1.8 (interquartile range [IQR] 1.4-2.3) and a median weighted RCR of 67.0 (IQR 21.1-212.7). Advanced academic rank and career longevity were associated with increased weighted RCR and total publication count. All subgroups analyzed had an RCR value above 1.0.
    CONCLUSIONS: ASES fellowship faculty are exceptionally productive and produce highly impactful research, as evidenced by the high median RCR value relative to the benchmark NIH RCR value of 1.0. This information can be used as a standard to assess the improvement of grant outcomes, promotion, fellowship education, and continued evaluation of research productivity in the shoulder and elbow community.

    A Bibliometric of Trends on Acupuncture Research About Migraine: Quantitative and Qualitative Analyses.
    Kelin He, Mingjie Zhan, Xinyun Li, Lei Wu, Kang Liang, Ruijie Ma.
      Introduction: Migraine is a common neurovascular disorder disease often characterized by episodic headaches that can develop chronic disorders. Acupuncture as a non-pharmacological therapy has been extensively used to manage migraine prevention and treatment in clinical practice. Many studies focused on acupuncture therapy for migraine, but none analyzed the publications quantitatively and qualitatively. The aim of this study is to show the recent researches and trend of advances in this field based on quantitative and qualitative analyses.Methods: Publications related to acupuncture research about migraine were retrieved from the Web of Science (WoS) Core Collection and Scopus database. The quantitative data analysis was performed to show the recent researches and trend of advances from six perspectives: annual scientific production, countries, institutions, authors, journals, and keywords. For the qualitative analysis, acupuncture research about migraine was analyzed from the top twenty most highly cited articles.
    Results: The number of annual scientific production steadily increased with some fluctuations over the years. The country and institutions contributing most to this field are China and Chengdu University of Traditional Chinese Medicine. Zhao Ling was the most relevant author in this field, Linde Klaus was the highly co-cited author. The leading journal regarding the number of selected articles was "Zhongguo Zhen Jiu". The top twenty most highly cited articles were divided into two categories: original articles and reviews. Among these two categories, original articles occupied the vast majority. Moreover, the real effectiveness of acupuncture for migraine prevention and treatment was the research frontier and hot spot.
    Conclusion: Results of our analysis indicate that the number of publications showed an overall increasing trend, demonstrating that this research field still has a promising future. In addition, more researchers will probably focus their work on the difference between verum acupuncture and usual care for preventing and treating migraine.

    Shuqing Shi, Jiayu Lv, Ruoning Chai, Wenjing Xue, Xia Xu, Bingxuan Zhang, Yumeng Li, Huaqin Wu, Qingqiao Song, Yuanhui Hu.
      Cardio-oncology has grown rapidly worldwide as an emerging interdisciplinary discipline over the past decade. In the present bibliometric review, we employed VOSviewer and Citespace software to describe the literature landscape concerning cardio-oncology from 2010 to 2022. As a result, a total of 1,194 relevant publications were identified in the Web of Science database with an increasing trend. The United States dominated the field during the research period, and Italy, England and Canada had emerged as significant contributors to the study. Ky.Bonnie, Herrmann.Joerg and Fradley.Michael G were the most productive researchers. JACC:CardioOncology was the journal dedicated to the discipline of cardio-oncology and had published the greatest number of papers.Vascular disease and atrial fibrillation have attracted much attention as the main cardiovascular burden. Immune checkpoint inhibitor-specific cardiovascular toxicity, biomarkers and imaging examination together with the prevention of cardio-oncology are potential research hotspots. Notably, basic research is lagging behind, for which more researches are needed to fill the gap. In conclusion, bibliometric analysis provided valuable information for the development of cardio-oncology, which is full of opportunities and challenges.

    A comparison of scientometric data and publication policies of ophthalmology journals.
    Ibrahim Ethem Ay, Gokhan Tazegul, Yaşar Duranoğlu.
      Purpose: This retrospective database analysis study aims to present the scientometric data of journals publishing in the field of ophthalmology and to compare the scientometric data of ophthalmology journals according to the open access (OA) publishing policies.Methods: The scientometric data of 48 journals were obtained from Clarivate Analytics InCites and Scimago Journal & Country Rank websites. Journal impact factor (JIF), Eigenfactor score (ES), scientific journal ranking (SJR), and Hirsch index (HI) were included. The OA publishing policies were separated into full OA with publishing fees, full OA without fees, and hybrid OA. The fees were stated as US dollars (USD).
    Results: Four scientometric indexes had strong positive correlations; the highest correlation coefficients were observed between the SJR and JIF (R = 0.906) and the SJR and HI (R = 0.798). However, journals in the first quartile according to JIF were in the second and third quartiles according to the SJR and HI and in the fourth quartile in the ES. The OA articles published in hybrid journals received a median of 1.17-fold (0.15-2.71) more citations. Only HI was higher in hybrid OA; other scientometric indexes were similar with full OA journals. Full OA journals charged a median of 1525 USD lower than hybrid journals.
    Conclusion: Full OA model in ophthalmology journals does not have a positive effect on the scientometric indexes. In hybrid OA journals, choosing to publish OA may increase citations, but it would be more accurate to evaluate this on a journal basis.

    Evolution of associating liver partition and portal vein ligation for staged hepatectomy from 2012 to 2021: A bibliometric analysis. Review.
    Junwei Zhang, Xiaobo Yang, Jinyu Fang, Quan-Cheng Cheng, Hui-Ru Ding, Yan-Rong Sun, Man Li, Jing-Lin Zhang, Lei Zhang, Haitao Zhao, Xinting Sang, Yi-Yao Xu, Wei-Guang Zhang, Xin Lu.
      BACKGROUND: Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) has become increasingly popular during the past few decades, and its indications have extended from patients with normal liver to post-chemotherapy patients and even patients with cirrhosis. However, few studies have assessed the publications in relation to ALPPS.METHODS: Web of Science was searched to identify studies related to ALPPS published from 2012 to 2021. The analysis was performed using the bibliometric package (Version 3.1.0) in R software.
    RESULTS: In total, 486 publications were found. These articles were published in 159 journals and authored by 2157 researchers from 694 organizations. The most prolific journal was Annals of Surgery (24 articles and 1170 citations). The most frequently cited article was published in Annals of Surgery (average citations, 72.7; total citations, 727). China was the most productive country for ALPPS publications but had comparatively less interaction with other countries. Both thematic evolution and co-occurrence network analysis showed low numbers of topics such as failure, resection, and safety among the publications but large numbers of highly cited papers on outcomes, prediction, mechanisms, multicenter analysis, and novel procedures such as liver venous deprivation. A total of 196 studies focused the clinical application of ALPPS, and most studies were IDEAL Stages I and II. The specific mechanism of ALPPS liver regeneration remains unclear.
    CONCLUSIONS: This is the first bibliometric analysis offering an overview of the development of ALPPS research publications. Our findings identified prominent studies, countries, institutions, journals, and authors to indicate the future direction of ALPPS research. The role of ALPPS in liver regeneration and the long-term results of ALPPS need further study. Future research directions include comparison of ALPPS with portal vein embolization, liver venous deprivation, and other two-stage hepatectomies as well as patients' quality of life after ALPPS.

    Using the H-index as a factor in the promotion of surgical faculty.
    Rongzhi Wang, Marshall Lewis, Rui Zheng-Pywell, Janet Julson, Mary Smithson, Herbert Chen.
      Introduction: Academic productivity is an important determinant for promotion. However, the measurement of academic productivity is ill-defined. The aim of this study is to demonstrate the academic productivity at the time of promotions at our institution.Methods: We reviewed the data of 33 faculty from Department of Surgery at our institution who were promoted from 2006 to 2021. Gender, academic productivity at hiring, and each promotion were obtained. Academic productivity was assessed by bibliometric indices including total number of publications and citations, and H-index, which were obtained from Web of Science. T-test, Mann-Whitney U test, Fisher's exact test and linear regression analysis were used to assess the association of H-index with length of promotion and gender. P < 0.050 were considered statistically significant.
    Results: The medians (interquartile ranges) of indexes at hiring, at promotions from assistant professors to associate professors, and from associate professors to full professors were 6.0 (1.5-9.5), 11.0 (9.0-18.0) and 17.0 (9.0-23.0) respectively. A simple linear regression showed significant correlation between the length of promotion to associate professors and their H-indexes at hiring. (F (1, 27) = 10.55, p = 0.003, R2 of 0.281.) There was no statistical significance in the difference of H-indexes at promotions between male and female faculty.
    Conclusion: At our institution, the median H-indexes at the time of promotions from assistant professor to associate professor and from associate professor to full professor are 11.0 and 17.0. Using the H-index as an objective measure can be a useful tool to junior surgical faculty as reference for applying promotion.

    Frontier and Hotspot Evolution in Cardiorenal Syndrome: a Bibliometric analysis from 2003 to 2022.
    Jiayu Lv, Yumeng Li, Shuqing Shi, Shixu Liu, Xia Xu, Huaqin Wu, Bingxuan Zhang, Qingqiao Song.
      In the last 20 years, the cardiorenal syndrome (CRS) field has received growing attention. There have been innovations in cardiorenal interaction patterns, biological markers and management of CRS, and even significant changes in its concept and the paradigm of CRS pathophysiology, which considerably increases the difficulties in understanding and in-depth study of this field. However, few study summarized the development process of CRS and critical issues. This review focuses on topical evolutions and emerging trends in CRS pathophysiology, diagnostic pathways, and treatment strategies. A quantitative retrospective analysis, visual review, and evaluation of 1452 articles published in the domain of CRS from 2003 to 2022 was conducted using a bibliometric analysis based on the classic CiteSpace and Vosviewer software rather than a general review, aiming to provide reasonable ideas and directions for future research on CRS.

    Scientific research competitiveness in hospitals: A narrative review of major hospital ranking systems in China.
    Dan Li, Jing Yu, Zhong-Wei Lv, Wen-Jun Gu, Ji-Yu Li.
      Background and Aims: Several hospital ranking systems have been created in China recently, but there is still a lack of comprehensive analysis of the weight and significance of scientific research in hospital ranking. The present study aimed to identify and analyze the role of scientific research competitiveness in various hospital ranking systems in China.Methods: Over 200 materials published between 2010 and 2020 and related to three mainstream hospital ranking systems in China were reviewed. The methodologies applied in the three ranking systems were analyzed and compared. In addition, the comparative learning and analysis of Top 10 and Top 46-55 hospitals according to the ranking system of China's Best Hospital Rankings was performed for a longitudinal study.
    Results: The three major hospital rankings had different scientific research capability ranking methodologies and emphases of scientific research evaluation systems. The most commonly used indicators were science citation index (SCI) publications, National Scientific Foundation of China funding, a number of national key laboratories, and a number of academicians. The relative standing of several top hospitals showed slightly different in the three major Chinese hospital ranking systems. For the longitudinal study, we found that the fluctuation of the ranking of the Top 46-55 hospitals was significantly higher than that of the Top 10 hospitals, in which scientific research played a vital role.
    Conclusion: The proportion of scientific research plays an important role in the hospital ranking systems. The quality and quantity of SCI publications, the key indicators of national projects, and top academic talents are the most important factors used to evaluate the level of hospital scientific research, and thus affect the ranking of hospitals.

      BACKGROUND: Gender composition among surgical academic leadership, including academic medical journals, disproportionately favors men and may inadvertently introduce a bias. An understanding of the factors associated with gender representation among urologic journals may aid in prioritizing an equitable balance.OBJECTIVE: To evaluate female representation on editorial boards of pre-eminent international urologic journals.
    DESIGN, SETTING, AND PARTICIPANTS: The names and position descriptions of urologic journal leadership appointees were collected in October 2021. Gender was assessed using gender-api.com or through personal title, as available. Journal characteristics were summarized using SCImago, a bibliometric indicator database extracted from Scopus journal data.
    OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: A multivariate logistic regression analysis was performed to describe associations between SCImago Journal Rank (SJR) quartile and geographic region with female gender representation. Quartile 1 (Q1) was considered the top quartile and Q4 the bottom quartile concordant with journal impact factor.
    RESULTS AND LIMITATIONS: A total of 105 urology-focused journals were identified with 5989 total editorial board members, including 877 (14.6%) female, 5112 (85.4%) male, and two nonbinary persons. Female representation differed significantly by journal leadership position, SJR quartile, and geographic region. On the multivariate analysis of overall female representation, Q1 journals had higher odds of female representation than Q2 and Q3 journals, and had no significant difference from Q4 journals. Additionally, compared with Western Europe, North American journals had 78% higher odds while Asiatic journals had 50% lower odds of female representation. This study is limited by the inability to account for outside factors that lead to invitation or acceptance of journal leadership positions.
    CONCLUSIONS: Contemporary female leadership at urology journals is about six times less common than male leadership across all journals, although trends in their proportion were noted when assessed by journal quartile and region. Addressing this gender imbalance represents an important step toward achieving gender equity in the field of urology.
    PATIENT SUMMARY: In this study, we looked at the gender balance of academic journal leaders who serve as gatekeepers for sharing urologic research with the public. We found that the most prestigious journals and those in western countries tended to have the highest female representation. We hope that these findings help the academic community recognize and improve gender representation.

    Comments on "Persistent, bioaccumulative, and toxic chemicals in insects: Current state of research and where to from here?"
    Meiting Huang.
      A recent study published in Science of the Total Environment conducted a systematic review of persistent, bioaccumulative, and toxic chemicals (PBTs) in insects using Web of Science Core Collection. Interestingly, a remarkable increase of human, animal, and vertebrate publications related to PBTs appeared in the early 1990s. Despite the authors' attempts to illustrate the anomalies from different perspectives, no rational explanation has been found yet. Quite interested in this abnormal phenomenon, we intend to join the academic discussion by pointing out some problems in the data retrieval and processing process in this review study and giving a more reasonable explanation for the surge of research publications in the early 1990s. Our new interpretations based on large-scale empirical data will help scholars make better use of this well-known and widely used database.

    Analysis of COVID-19 publications in the Indian Journal of Ophthalmology during two years of the pandemic and their impact on ophthalmic literature.
    Bharat Gurnani, Kirandeep Kaur.
      Purpose: To perform a comprehensive analysis of COVID-19 publications published in the Indian Journal of Ophthalmology (IJO) during the two years of the pandemic and to study their impact on ophthalmic literature.Methods: : A retrospective analysis was performed of all expedited COVID-19 articles published in IJO from April 2020 to March 2022. The data was obtained from the official website of IJO, editor IJO monthly emails, and PubMed database. The data was then extracted as XML into Microsoft Access for scientometric analysis. The expedited articles were segregated into different categories: original, review, case report/series, letter to the editor, commentary, current ophthalmology, consensus criteria, perspective, innovations, ophthalmic images, photoessays, research methodology, and surgical techniques. The monthly data was analyzed and COVID-19 articles were assessed for subspecialty-wise distribution, number of citations, monthly growth rate, and their impact on ophthalmic literature.
    Results: A total of 431 COVID-19 related articles were published during the study period. The majority of the articles were letters to the editor (158, 36.65%) followed by original articles (97, 22.50%), and commentaries (53, 12.29%). The least were perspectives and ophthalmic images (2, 0.46%) each followed by consensus criteria (1, 0.23%). The maximum publications came in July 2020 (44, 10.20%) followed by December 2021 (37, 8.58%) and October 2021 (36, 8.35%), and the least were in April 2020 (1, 0.23%). Considering subspecialty, a majority of the articles were related to general ophthalmology (156, 36.19%), and the least was in oncology (2, 0.46%). The maximum number of citations were attracted by original articles (97, 1146 (11.81)), which were approximately 1.5 times higher than the letters to the editor (158, 743 (4.70)) and 3 times higher than review articles (9, 387 (43)). Among specialties, the maximum number of citations were gathered by general ophthalmology (156, 1320 (8.46)) followed by oculoplasty (36, 592 (16.44)) due to the concurrent mucormycosis epidemic.
    Conclusion: : IJO opened a window of opportunity for authors by publishing quality expedited articles. Evidence-based orbital mucormycosis and general ophthalmology publications gathered most of the attention due to their heterogeneous presentation. The peak of the first wave (June-July 2020) and the October and December 2021 issues had maximum number of COVID-19 articles.

    The AAOS 2019 Clinical Practice Guidelines for the Management of Rotator Cuff Injuries Are Unbiased and Incorporate a Diverse Body of Literature.
    Jason Lee, Daniel W Griepp, Colin J Burgess, Brandon Petrone, Adam D Bitterman, Randy M Cohn.
      Purpose: To analyze the scientific research that formed the basis of the 2019 American Academy of Orthopaedic Surgeons (AAOS) clinical practice guidelines for the management of rotator cuff injuries.Methods: All studies cited in the 2019 AAOS clinical practice guidelines for the management of rotator cuff injuries were extracted and categorized. Extracted data included type of study, number of patients, level of evidence, journal of publication, impact factor, year of publication, country of origin, contributing authors, affiliated institutions, and significant findings. Data were analyzed to determine time from publication to implementation, level of evidence, and frequency of cited journals and authors.
    Results: The studies cited in the guideline included 15,130 patients from 140 studies published between 1994 and 2018. The overall mean time from article publication to 2019 AAOS clinical practice guidelines was 4.76 ± 2.23 years. Of articles published in 2010 to 2019, 64 studies were cited in the strong recommendation strength subcategory, and 57 articles were cited in the moderate recommendation strength subcategory. Articles published in Journal of Shoulder & Elbow Surgery and Arthroscopy were cited most frequently. The most frequent authors were J. H. Oh, R. Z. Tashjian, S. H. Kim, N. Maffulli, and J. C. Yoo.
    Conclusions: The 2019 AAOS CPG reference a diverse number of journals and authors, appearing to be impartial. Furthermore, prompt time from publication to implementation in the Guidelines indicates that it is possible to influence clinical guidelines with recent work.
    Clinical Relevance: An analysis of the scientific research that forms the basis of the AAOS Clinical Practice Guidelines for the Management of Rotator Cuff Injuries can provide valuable information about the quality of the Guidelines.

    Qian Bi, Zheng Miao, Jing Shen, Hao Wang, Kai Kang, Junjie Du, Fuquan Zhang, Shaoping Fan.
      Purpose: The aim of this study is to visualize and analyze the research hot pots in radiation therapy for rectal cancer and provide researchers with a clear and visual reference for subsequent studies. Methods: The literature scientometric analysis about "external beam radiation therapy (EBRT) for rectal cancer" was made through the WoSCC (2010 to 2019). And the data was visualized and analyzed by the Microsoft Office Excel (2019) and CiteSpace (V. 5.7.R1). Results: 4,263 relevant articles were downloaded. The number of published articles per year has been increasing (2010-2020). The United States published the highest number of articles. The UK has the strongest partnerships with other countries/regions. Leiden University has the highest number of published articles and University Texas MD Anderson Cancer Center has extensive collaborations with other academic institutions. The number of articles published in the Diseases of the Colon Rectum is the most, and the Journal of Clinical Oncology is the most cited. 27 articles became the strongest burst citations lasting until 2020. In recent years, a lot of research has been done on "watch and wait", "short-course radiotherapy", "MRI", "neoadjuvant radiotherapy, "MRI in rectal cancer", "chemotherapy regimen improvement", "adding adjuvant chemotherapy", and so on. Conclusion: The current research hot pots may be the "watch and wait", "short-course radiotherapy", "MRI", "neoadjuvant chemoradiotherapy", "MRI in rectal cancer", "chemotherapy regimen improvement", and "adding adjuvant chemotherapy".

    Bibliometric Approach to Evaluating the Impact of a Building Interdisciplinary Research Careers in Women's Health K12 Research Career Development Program.
    Jerica M Berge, Kait Macheledt, Caitlin Bakker, Sharon Allen, Bharat Thyagarajan, Jean F Wyman.
      Background: Mentored research career development programs are excellent training opportunities for junior faculty/early-stage investigators to transition into independent research careers. However, there is limited evidence that provides guidance on best practices for measuring the impact and reach of these programs, both for individual Scholars and the program as a whole. This article evaluates both the individual and overall impact of the Building Interdisciplinary Research Careers in Women's Health (BIRCWH) National Institutes of Health research career development award at the University of Minnesota. Materials and Methods: BIRCWH Scholars (n = 16) and a comparison group (n = 17) were evaluated on traditional metrics (e.g., publications, grant funding) in addition to bibliometrics (e.g., network growth, interdisciplinary collaborations, international reach, policy impact). Results: Traditional metric findings showed that BIRCWH Scholars had significantly more publications from pre- to post-BIRCWH experience than the comparison group and more grant funding. Bibliometric findings showed exponential network growth, interdisciplinary collaborations, international citations, and policy impact from pre- to post-BIRCWH Scholar experience. Conclusion: Findings from this evaluation have potential important implications. At the Scholar level, the results can be used to provide evidence of research impact in materials developed for merit review and promotion as well as in job and research grant applications. At the program level, the results can be used at the institutional level to gain broad administrative support and leverage additional funds for program activities and for evidence of program success for continuation funding from federal agencies.

    Research artifacts and citations in computer systems papers.
    Eitan Frachtenberg.
      Research in computer systems often involves the engineering, implementation, and measurement of complex systems software and data. The availability of these artifacts is critical to the reproducibility and replicability of the research results, because system software often embodies numerous implicit assumptions and parameters that are not fully documented in the research article itself. Artifact availability has also been previously associated with higher paper impact, as measured by citations counts. And yet, the sharing of research artifacts is still not as common as warranted by its importance. The primary goal of this study is to provide an exploratory statistical analysis of the artifact-sharing rates and associated factors in the research field of computer systems. To this end, we explore a cross-sectional dataset of papers from 56 contemporaneous systems conferences. In addition to extensive data on the conferences, papers, and authors, this analyze dataset includes data on the release, ongoing availability, badging, and locations of research artifacts. We combine this manually curated dataset with citation counts to evaluate the relationships between different artifact properties and citation metrics. Additionally, we revisit previous observations from other fields on the relationships between artifact properties and various other characteristics of papers, authors, and venue and apply them to this field. The overall rate of artifact sharing we find in this dataset is approximately 30%, although it varies significantly with paper, author, and conference factors, and it is closer to 43% for conferences that actively evaluated artifact sharing. Approximately 20% of all shared artifacts are no longer accessible four years after publications, predominately when hosted on personal and academic websites. Our main finding is that papers with shared artifacts averaged approximately 75% more citations than papers with none. Even after controlling for numerous confounding covariates, the release of an artifact appears to increase the citations of a systems paper by some 34%. This metric is further boosted by the open availability of the paper's text.

    A Meta-Overview and Bibliometric Analysis of Resilience in Spatial Planning - the Relevance of Place-Based Approaches.
    Gabriela Carmen Pascariu, Alexandru Banica, Peter Nijkamp.
      This study offers a literature review and bibliometric analysis aiming to enhance our understanding of the actual contribution of resilience approaches to spatial and territorial development and planning studies. Using citation link-based clustering and statistical text-mining techniques (in terms of prevalence of topics, over time, extraction of relevant terms, keywords frequencies), our study maps scientific domains that include the spatial dimension of resilience thinking. It offers a systematic assessment of modern approaches by connecting profoundly theoretical views to more instrumental and policy-oriented approaches. Firstly, the theoretical background of spatial resilience used in numerous studies in various fields is analysed from the viewpoint of the type of embedded resilience (engineering, ecological, social-ecological, economic, social etc.). Secondly, we review and discuss the significance of three main and consistent research directions in terms of different scales and political/institutional contexts that matter from the viewpoint of spatial and territorial planning. Our findings show that spatial resilience debates are far from being settled, as according to many scientists, resilience measurements are often based on technical-reductionist frameworks that cannot comprehensively reflect the complex systems and issues they address. Our conclusions highlight the necessity of a harmonized framework and integrated perspective on resilience in sustainable territorial planning and development, in both theoretical and empirical contexts.

    Circular and green economy: the state-of-the-art.
    Fabio G Santeramo.
      Circular and green economy are relevant issues in the agricultural sector, and animate the academic and policy debates: they contribute to identify and address the environmental and social problems raised by the economic development of the global economy. This study aims at reviewing the literature on circular and green economy, with a particular emphasis on the agri-food systems and their supply chains. It includes a systematic literature review and a bibliometric analysis, based on 1,061 documents that are indexed in the Scopus database. The bibliometric analysis identifies dominant thematic research areas, such as "Circular Economy", "Green Economy", "Food Waste", and "Environmental Impacts". The analysis of publication patterns and emerging topics suggests that future research should focus on the nexus "food waste and environmental impacts", and emphasizes the need to adopt a multidiscipinary approach to investigate the complex nexus between the food waste and the environment.

    Gender Inequities in Transfusion Medicine Society Recognition Awards.
    Jeremy W Jacobs, Brian D Adkins, Laura D Stephens, Jennifer S Woo, Garrett S Booth.
      Award recognition by medical societies contributes to professional development, career networking, and academic rank promotion. Previous research has demonstrated that men are the predominant recipients of medical society awards across multiple medical specialties; as such, we sought to understand whether women are underrepresented as award recipients amongst blood banking and transfusion medicine (BBTM) medical societies. We examined recipients of 10 total awards from the Association for the Advancement of Blood and Biotherapies (AABB) and the American Society for Apheresis. Additional evaluation of AABB's National Blood Foundation Hall of Fame inductees was conducted. Gender was determined via online review of pronouns, online photographs, and a web-based gender identification application. Award recipient gender was analyzed and coded independently by two authors, and any discrepancies were adjudicated by author consensus. Of the 330 AABB awards since 1954, significantly more have been conferred to men (81.5%, 269/330; P < .001). Of the 51 American Society for Apheresis awards presented since 1993, 64.7% (33/51; P = .23) have been conferred to men. Compared to the first 10 years of the AABB awards (1954-1964), there has been a significant increase in the proportion of women award recipients in the most recent decade (2010-2021) (18.5%, 5/27 vs 29.4%, 30/102; P < .001). However, additional temporal analysis of the modern era (2000-2021) revealed men have received significantly more AABB awards than women (77.4%, 144/186 vs 22.6%, 42/186; P < .001). Our findings highlight both historic and contemporary inequity for recognition of women within BBTM. Without improvement, gender parity among BBTM award recipients will take approximately 120 years (11% increase in women awardees in 60 years); thus, to ensure the BBTM field continues to progress, we must advocate for equity among all members, including but not limited to gender, race, and ethnicity. Strategies to enhance equity include transparency in the identities of award nominees, award recipients, and individuals on selection committees, the gender ratios of both award nominees and recipients, and implementation of methods for tracking individual demographics over time. These strategies would permit temporal analysis of the ratio of award nominee gender to award recipient gender, and assessment as to whether potential gender inequities improve over time.

    A comprehensive analysis of evolution and underlying connections of water research themes in the 21st century.
    Xueming Chen, Huiqi Chen, Linyan Yang, Wei Wei, Bing-Jie Ni.
      This work aimed to reflect the advancements in water-related science, technology, and policy and shed light on future research opportunities related to water through a systematic overview of Water Research articles published in the first 21.5 years of the 21st century. Specific bibliometric analyses were performed to i) reveal the temporal and spatial trends of water-related research themes and ii) identify the underlying connections between research topics. The results showed that while top topics including wastewater (treatment), drinking water, adsorption, model, biofilm, and bioremediation remained constantly researched, there were clear shifts in topics over the years, leading to the identification of trending-up and emerging research topics. Compared to the first decade of the 21st century, the second decade not only experienced significant uptrends of disinfection by-products, anaerobic digestion, membrane bioreactor, advanced oxidation processes, and pharmaceuticals but also witnessed the emerging popularity of PFAS, anammox, micropollutants, emerging contaminants, desalination, waste activated sludge, microbial community, forward osmosis, antibiotic resistance genes, resource recovery, and transformation products. On top of the temporal evolution, distinct spatial evolution existed in water-related research topics. Microplastics and Covid-19 causing global concerns were hot topics detected, while metagenomics and machine learning were two technical approaches emerging in recent years. These consistently popular, trending-up and emerging research topics would most likely attract continuous/increasing research input and therefore constitute a major part of the prospective water-related research publications.

    The European Heart Journal: fulfilling the mission.
    EHJ Editorial Board
      In September 2020, the new Editors of the European Heart Journal (EHJ) wrote the following in their inaugural editorial: "The fundamental mission of the Journal remains the reduction of the global burden of cardiovascular disease. We aspire to advance this aim by worldwide teamwork to communicate practice-changing research, inspire clinical cardiologists, and pursue rigour and transparency in the application of science at the service of human health. The Journal will strive to lead the field in its impact, influence, and reach". After more than one year of experience the Editors hope the cardiological community will agree that they are fulfilling this mission. As stewards of the EHJ, the Editor's primary goal is not solely to achieve a high Impact Factor (which attests to the scientific quality and influence of our publications) but also to elevate the practice of cardiovascular medicine worldwide. Accordingly, various initiatives of the EHJ strive to strengthen further links among Editors, Authors, Reviewers and Readers through a series of coordinated and diverse activities, including webinars, active social media presence, and active participation at congresses worldwide. The Editors are proud to serve one of the most important scientific journals in cardiovascular medicine.

    Bibliometric Analysis of γδ T Cells as Immune Regulators in Cancer Prognosis.
    Bing Liu, Xu He, Yong Wang, Jian-Wen Huang, You-Bing Zheng, Yong Li, Li-Gong Lu.
      γδ T cells are one of only three immune cell types that express antigen receptors that undergo somatic recombination, and they contribute to immune responses to infection, cellular transformation, and tissue damage. As a "bridge" between the innate and adaptive immune systems, γδ T cells have been noted to be involved in various immune responses during cancer progression. The purpose of our study was to review current published information on γδ T cells and investigate their functions in different types of malignancy using bibliometric and bioinformatic methods. Our results indicated that studies on γδ T cells and cancer progression increased from 2014, and the number had peaked by 2021. We discovered that there is international cooperation in the performance of studies among 26 countries, where China was identified as the most productive with the highest citations. Using keyword co-occurrence analysis, we found that among all the cancer types investigated, gastric and breast cancers were most closely related to γδ T cells. Furthermore, interleukin (IL)-17 and IL-2 were the most common cytokines linked to γδ T cells and our investigation of their potential involvement in the prognosis of gastric and breast cancers, identified their different roles in various malignancies. Thus, we concluded that γδ T cells might influence the progression of different cancers in diverse ways.

    Trends in dermatology eponyms.
    Lin He, Toby C Cornish, Larry J Kricka, Travis W Vandergriff, Kim Yancey, Khang Nguyen, Jason Y Park.
      Background: Eponyms are ubiquitous in dermatology; however, their usage trends have not been studied.Objective: To characterize the usage of eponyms in dermatology from 1880 to 2020.
    Methods: Candidate eponyms were collected from a textbook and an online resource. A subset of these eponyms was deemed to be dermatology-focused by a panel of experienced dermatologists. Python scripts were used to permute eponyms into multiple variations and automatically search PubMed using BioPython's Entrez library.
    Results: The dermatologist panel designated 373 of 529 candidate eponyms as dermatology-focused. These eponyms were permuted into 3159 variations and searched in PubMed. The highest occurring dermatology-focused eponyms (DFEs) in the year 2020 included Leishmania, Behçet syndrome, Kaposi sarcoma, Langerhans cell histiocytosis, and Mohs surgery. Increased DFE usage in the general medical literature parallels the overall increase in the use of other eponyms in the medical literature. However, in the most cited dermatology journals, DFE usage did not increase in the past decade. There were several eponyms with decreased usage.
    Limitations: This study is limited to the publications in PubMed; only titles and abstracts could be queried.
    Conclusion: DFEs are increasing in usage in the general medical literature, but the usage of eponyms in the most cited dermatology journals has plateaued.

    Analysis of Ecuador's SCOPUS scientific production during the 2001-2020 period by means of standardized citation indicators.
    V Rodríguez, M Flores-Sanchez, C H Zambrano, L Rincón, J L Paz, F J Torres.
      An analysis of the scientific production of Ecuador is performed by means of the composite indicator computed for Ecuador-based authors as compared to their counterparts of other South American countries. The dataset employed was obtained from the Databricks platform of the ELSEVIER's International Center for Science Research, ICSR. Therefore, this analysis is limited to the metadata of the documents published in journals indexed in SCOPUS. Comparison of the results obtained for two decades: 2001-2010 and 2011-2020 showed that the number of Ecuador-based researchers has significantly increased in different areas of knowledge. Moreover, comparison between the total number of authors that worked in Ecuador at any given year of the 2011-2020 period and the number of authors that are still working in this country up to the date of the data extraction (i.e., June 2021) showed an average of ∼68% of permanency. Analysis of the percentage distribution in terms of range quarters of the composite indicator (i.e., Q4: 0-1.5, Q3: 1.5-3.0, Q2: 3.0-4.5, and Q1: 4.5-6.0) showed that nearly the totality of the Ecuador-based researchers has composite indicators that lay in the Q4 and Q3 ranges for all the scientific fields considered. The latter was observed to be an effect of the scientific impact of South American countries, with larger investments in science and technology in comparison to Ecuador (i.e., Argentina, Brazil, and Chile). Exclusion of this group of countries in the calculation of the composite indicator of Ecuador-based authors resulted in a noticeable increment of scientists with composite indicators within Q2. Finally, our results suggest, in agreement with previous studies, a correlation between the sustained growth of scientific productivity in the decade 2011-2020 with the scientific programs and policies created by the state, where the initiative of scientific culture is shown as a strategy for growth and development.

    Societal impact of university research in the written press: media attention in the context of SIUR and the open science agenda among social scientists in Flanders, Belgium.
    Hans Jonker, Florian Vanlee, Walter Ysebaert.
      Transferring scientific knowledge to non-academic audiences is an essential aspect of the open science agenda, which calls for scholars to pursue a popularization of their research. Accordingly, purposefully introducing scientific insights to the public at large is almost univocally deemed commendable. Indeed, in today's models of research evaluation, the objects and activities considered are being extended beyond peer-reviewed journal articles to include non-scholarly popular communication. Although altmetrics offer one instrumental way to count some interactions with lay audiences, their reliance on social media makes them susceptible to manipulation, and mostly reflect circulation among niche audiences. In comparison, attention from non-scholarly media like newspapers and magazines seems a more relevant pathway to effectuate societal impact, due to its recognition in qualitative assessment tools and its broad, societal reach. Based on a case study of social scientists' attention by newspapers and magazines in Flanders (northern Dutch-speaking region of Belgium) in 2019, this paper highlights that frequent participation in the public debate is reserved for high-status researchers only. Results show highly skewed media appearance patterns in both career position and gender, as eight male professors accounted for almost half of all 2019 media attention for social scientists. Because media attention is highly subject-dependent moreover, certain disciplines and fields offer easier pathways to popularization in media than others. Both the open science agenda and research assessment models value presence of researchers in popular media, adding written press attention to existing evaluation assessments however would disproportionately disadvantage early career researchers and exacerbate existing inequalities in academia.Supplementary Information: The online version contains supplementary material available at 10.1007/s11192-022-04374-x.

    And the credit goes to … - Ghost and honorary authorship among social scientists.
    Gernot Pruschak, Christian Hopp.
      The proliferation of team-authored academic work has led to the proliferation of two kinds of authorship misconduct: ghost authorship, in which contributors are not listed as authors and honorary authorship, in which non-contributors are listed as authors. Drawing on data from a survey of 2,222 social scientists from around the globe, we study the prevalence of authorship misconduct in the social sciences. Our results show that ghost and honorary authorship occur frequently here and may be driven by social scientists' misconceptions about authorship criteria. Our results show that they frequently deviate from a common point of authorship reference (the ICMJE authorship criteria). On the one hand, they tend to award authorship more broadly to more junior scholars, while on the other hand, they may withhold authorship from senior scholars if those are engaged in collaborations with junior scholars. Authorship misattribution, even if it is based on a misunderstanding of authorship criteria rather than egregious misconduct, alters academic rankings and may constitute a threat to the integrity of science. Based on our findings, we call for journals to implement contribution disclosures and to define authorship criteria more explicitly to guide and inform researchers as to what constitutes authorship in the social sciences. Our results also hold implications for research institutions, universities, and publishers to move beyond authorship-based citation and publication rankings in hiring and tenure processes and instead to focus explicitly on contributions in team-authored publications.

    Artificial intelligence in COVID-19 evidence syntheses was underutilized, but impactful: a methodological study.
    Juan R Tercero-Hidalgo, Khalid S Khan, Aurora Bueno-Cavanillas, Rodrigo Fernández-López, Juan F Huete, Carmen Amezcua-Prieto, Javier Zamora, Juan M Fernández-Luna.
      OBJECTIVE: A rapidly developing scenario like a pandemic requires the prompt production of high-quality systematic reviews, which can be automated using artificial intelligence (AI) techniques. We evaluated the application of AI tools in COVID-19 evidence syntheses.STUDY DESIGN: After prospective registration of the review protocol, we automated the download of all open-access COVID-19 systematic reviews in the COVID-19 Living Overview of Evidence database, indexed them for AI-related keywords, and located those that used AI tools. We compared their journals' JCR Impact Factor, citations per month, screening workloads, completion times (from pre-registration to preprint or submission to a journal) and AMSTAR-2 methodology assessments (maximum score 13 points) with a set of publication date matched control reviews without AI.
    RESULTS: Of the 3999 COVID-19 reviews, 28 (0.7%, 95% CI 0.47-1.03%) made use of AI. On average, compared to controls (n=64), AI reviews were published in journals with higher Impact Factors (median 8.9 vs 3.5, p<0.001), and screened more abstracts per author (302.2 vs 140.3, p=0.009) and per included study (189.0 vs 365.8, p<0.001) while inspecting less full texts per author (5.3 vs 14.0, p=0.005). No differences were found in citation counts (0.5 vs 0.6, p=0.600), inspected full texts per included study (3.8 vs 3.4, p=0.481), completion times (74.0 vs 123.0, p=0.205) or AMSTAR-2 (7.5 vs 6.3, p=0.119).
    CONCLUSION: AI was an underutilized tool in COVID-19 systematic reviews. Its usage, compared to reviews without AI, was associated with more efficient screening of literature and higher publication impact. There is scope for the application of AI in automating systematic reviews.

    New Kids on the Block? A Bibliometric Analysis of Emerging COVID-19-Trends in Leadership Research.
    Robin Bauwens, Saša Batistič, Steven Kilroy, Sanne Nijs.
      The COVID-19 pandemic has resulted in unprecedented challenges for society. The effects on organizations have been drastic and such tough times have demanded new organizational solutions as well as strong and new forms of organizational leadership. Leadership scholars have accelerated their research efforts in the quest to identify what is needed to lead in these uncertain times. In this paper, we adopt a bibliometric review to unravel the emerging trends in leadership research in the wake of the COVID-19 pandemic, and in doing so, identify commonalities and divergences in these themes with respect to leadership approaches and assess potential avenues for future research. The findings reveal that research on the topic has emerged along six main clusters: (1) leadership and employee health during pandemic times, (2) public leadership, (3) leadership in health care, (4) leadership and diversity, (5) educational leadership, and (6) leadership and persuasive communication. The findings reveal that across these clusters, the pandemic has sparked research on leadership approaches that deal with change and uncertainty as well as those that are less hierarchical and person centered in nature. We also notice a novel attention to context. Rather than "new kids on the block," these trends are largely continuations of established leadership theories and approaches that see their particular importance increase in this unprecedented situation. Finally, we outline some distinct avenues for further research with regard to leadership in COVID-19 times.

    Downstream retraction of preprinted research in the life and medical sciences.
    Michele Avissar-Whiting.
      Retractions have been on the rise in the life and clinical sciences in the last decade, likely due to both broader accessibility of published scientific research and increased vigilance on the part of publishers. In this same period, there has been a greater than ten-fold increase in the posting of preprints by researchers in these fields. While this development has significantly accelerated the rate of research dissemination and has benefited early-career researchers eager to show productivity, it has also introduced challenges with respect to provenance tracking, version linking, and, ultimately, back-propagation of events such as corrigenda, expressions of concern, and retractions that occur on the journal-published version. The aim of this study was to understand the extent of this problem among preprint servers that routinely link their preprints to the corollary versions published in journals. To present a snapshot of the current state of downstream retractions of articles preprinted in three large preprint servers (Research Square, bioRxiv, and medRxiv), the DOIs of the journal-published versions linked to preprints were matched to entries in the Retraction Watch database. A total of 30 retractions were identified, representing only 0.01% of all content posted on these servers. Of these, 11 retractions were clearly noted by the preprint servers; however, the existence of a preprint was only acknowledged by the retracting journal in one case. The time from publication to retraction averaged 278 days, notably lower than the average for articles overall (839 days). In 70% of cases, retractions downstream of preprints were due-at least in part-to ethical or procedural misconduct. In 63% of cases, the nature of the retraction suggested that the conclusions were no longer reliable. Over time, the lack of propagation of critical information across the publication life cycle will pose a threat to the scholarly record and to scientific integrity. It is incumbent on preprint servers, publishers, and the systems that connect them to address these issues before their scale becomes untenable.

    Becoming metrics literate: An analysis of brief videos that teach about the h-index.
    Lauren A Maggio, Alyssa Jeffrey, Stefanie Haustein, Anita Samuel.
      INTRODUCTION: Academia uses scholarly metrics, such as the h-index, to make hiring, promotion, and funding decisions. These high-stakes decisions require that those using scholarly metrics be able to recognize, interpret, critically assess and effectively and ethically use them. This study aimed to characterize educational videos about the h-index to understand available resources and provide recommendations for future educational initiatives.METHODS: The authors analyzed videos on the h-index posted to YouTube. Videos were identified by searching YouTube and were screened by two authors. To code the videos the authors created a coding sheet, which assessed content and presentation style with a focus on the videos' educational quality based on Cognitive Load Theory. Two authors coded each video independently with discrepancies resolved by group consensus.
    RESULTS: Thirty-one videos met inclusion criteria. Twenty-one videos (68%) were screencasts and seven used a "talking head" approach. Twenty-six videos defined the h-index (83%) and provided examples of how to calculate and find it. The importance of the h-index in high-stakes decisions was raised in 14 (45%) videos. Sixteen videos (52%) described caveats about using the h-index, with potential disadvantages to early researchers the most prevalent (n = 7; 23%). All videos incorporated various educational approaches with potential impact on viewer cognitive load. A minority of videos (n = 10; 32%) displayed professional production quality.
    DISCUSSION: The videos featured content with potential to enhance viewers' metrics literacies such that many defined the h-index and described its calculation, providing viewers with skills to recognize and interpret the metric. However, less than half described the h-index as an author quality indicator, which has been contested, and caveats about h-index use were inconsistently presented, suggesting room for improvement. While most videos integrated practices to facilitate balancing viewers' cognitive load, few (32%) were of professional production quality. Some videos missed opportunities to adopt particular practices that could benefit learning.

    Impact and legacy of the highly cited paper by Blaxter and Clapperton (1965) Prediction of the amount of methane produced by ruminants. Br. J. Nutr. 19, 511-522.
    R John Wallace.
      The paper by K.L. Blaxter and J. L. Clapperton (1965) Prediction of the amount of methane produced by ruminants. Br. J. Nutr. 19, 511-522 has been cited 656 times according to Web of Science and continues to be cited with increasing frequency to the present day. The analysis described in the paper, or meta-analysis as it would be known now, is of methane production from cattle and sheep based on 48 trials using closed-circuit respiration chambers, all carried out at the Hannah Research Institute, Ayr, UK, between 1955 and 1965. Methane emissions per unit of diet fed were shown to vary depending on diet, level of feeding and individual animal. As such, previous notions that methane emissions were essentially proportional to energy intake were set aside. The main reasons for the paper's continuing citation are the set of equations that can be used to predict methane emissions from ruminants when the technically demanding respiration chambers are unavailable and that it was the first definitive study to describe the complexities of methane emissions with respect to animals and diets. The paper thus provided abundant insights of the relations between ruminant methane emissions and nutritional biology, and rumen microbiology in particular, that have informed countless research projects in the intervening half-century. Given the importance of methane as a greenhouse gas in the climate change scenario, these insights are at least as relevant today as they were in 1965.

    Lack of Representation in Psychiatric Research: A Data-Driven Example From Scientific Articles Published in 2019 and 2020 in the American Journal of Psychiatry.
    Sarah L Pedersen, Rachel Lindstrom, Paula M Powe, Kelly Louie, César Escobar-Viera.
      OBJECTIVE: The authors examined representation and accuracy of descriptions of sociodemographic identities in psychiatric research through quantifying data contained in recently published articles from a high-impact psychiatry journal.METHODS: Sociodemographic data were aggregated from articles (i.e., studies that provide information on individual samples) published in the American Journal of Psychiatry in 2019 and 2020 (N=125). Articles were coded by two raters for sociodemographic data, acknowledgment of lack of representation as a limitation, and focus on health disparities or inequities.
    RESULTS: While 90% of studies provided the age of participants and 84% provided information about the sex/gender of participants, only 43% presented information about the racial or ethnicity identities of participants. One study reported the sexual identity of participants. Lack of representation relative to 2019 U.S. Census data was found for multiple racial groups, Latino/Hispanic individuals, and women (genetic studies only). Only 25% of studies acknowledged lack of representation as a limitation, and two studies focused on health disparities or inequities.
    CONCLUSIONS: These findings highlight a need to increase representation in psychiatric research and improve accuracy of language when describing the sociodemographic characteristics of participants.

    [Mapping of research protocols, publications, and collaborations on COVID-19 in Latin America and the CaribbeanMapeamento de protocolos de pesquisa, publicações e colaborações sobre COVID-19 na América Latina e no Caribe].
    Evelina Chapman, Eduardo Illanes, Ludovic Reveiz, Carla Saenz.
      Objective: To map research protocols, publications, and collaborations on coronavirus disease 2019 (COVID-19) developed in Latin America and the Caribbean (LAC).Methods: Included were research protocols registered in international platforms and research publications containing populations, data, or authors from LAC. The source of information for protocols was primarily the International Clinical Trial Registry Platform (ICTRP) of the World Health Organization; for publications, specific electronic databases and repositories pertaining to COVID-19 were used. The search for publications was conducted up to 11 November; the search for protocols, up to 30 November 2020 (both dates inclusive). Data was extracted from protocols using standardized variables from the ICTRP, and from publications following pre-established criteria.
    Results: Among the protocols, 63.0% were therapeutic studies, 10% focused on prevention, and 45% were collaborative; 64% of the protocols received no funding from industry; 23% of the publications were not peer-reviewed and 23% were collaborative in nature. The most frequent study designs were systematic reviews and cross-sectional studies; 47.1% of studies were conducted in health facilities and 22% in community settings; 38.0% focused on diagnosis and 27.9% on prognosis. A qualitative synthesis was performed by line of care and approach strategies.
    Conclusions: There was an increase in the number of collaborative research studies relative to earlier studies and in protocols not funded by industry. The proposed research agenda was covered in large part as the pandemic unfolded.
