    Antimicrobial resistance and machine learning: past, present, and future.
    Faiza Farhat, Md Tanwir Athar, Sultan Ahmad, Dag Øivind Madsen, Shahab Saquib Sohail.
      Machine learning has become ubiquitous across all industries, including the relatively new application of predicting antimicrobial resistance. As the first bibliometric review in this field, we expect it to inspire further research in this area. The review employs standard bibliometric indicators such as article count, citation count, and the Hirsch index (H-index) to evaluate the relevance and impact of the leading countries, organizations, journals, and authors in this field. VOSviewer and Biblioshiny programs are utilized to analyze citation and co-citation networks, collaboration networks, keyword co-occurrence, and trend analysis. The United States has the highest contribution with 254 articles, accounting for over 37.57% of the total corpus, followed by China (103) and the United Kingdom (78). Among 58 publishers, the top four publishers account for 45% of the publications, with Elsevier leading with 15% of the publications, followed by Springer Nature (12%), MDPI, and Frontiers Media SA with 9% each. Frontiers in Microbiology is the most frequent publication source (33 articles), followed by Scientific Reports (29 articles), PLoS One (17 articles), and Antibiotics (16 articles). The study reveals a substantial increase in research and publications on the use of machine learning to predict antibiotic resistance. Recent research has focused on developing advanced machine learning algorithms that can accurately forecast antibiotic resistance, and a range of algorithms are now being used to address this issue.

       Background: Chronic pain poses a significant social burden. Spinal cord stimulation (SCS) is considered to be the most promising treatment for refractory pain. The aim of this study was to summarize the current research hotspots on SCS for pain treatment during the past two decades and to predict the future research trends by bibliometric analysis.
    Methods: The literature over the last two decades (2002-2022) which was related to SCS in pain treatment was obtained from the Web of Science Core Collection. Bibliometric analyses were conducted based on the following aspects: (1) Annual publication and citation trends; (2) Annual publication changes of different publication types; (3) Publications and citations/co-citations of different country/institution/journal/author; (4) Citations/co-citation and citation burst analysis of different literature; and (5) Co-occurrence, cluster, thematic map, trend topics, and citation burst analysis of different keywords. (6) Comparison between the United States and Europe. All analyses were performed on CiteSpace, VOSviewer, and R bibliometrix package.
    Results: A total of 1,392 articles were included in this study, with an increasing number of publications and citations year by year. The most highly published type of literature was clinical trial. United States was the country with the most publications and citations; Johns Hopkins University was the institution with the most publications; NEUROMODULATION published the most papers; the most published author was Linderoth B; and the most cited paper was published in the PAIN by Kumar K in 2007. The most frequently occurring keywords were "spinal cord stimulation," "neuropathic pain," and "chronic pain," etc.
    Conclusion: The positive effect of SCS on pain treatment has continued to arouse the enthusiasm of researchers in this field. Future research should focus on the development of new technologies, innovative applications, and clinical trials for SCS.

       Objective: The aim of this paper is to analyze the application of machine learning in heart failure-associated diseases using bibliometric methods and to provide a dynamic and longitudinal bibliometric analysis of heart failure-related machine learning publications.
    Materials and methods: Web of Science was screened to gather the articles for the study. Based on bibliometric indicators, a search strategy was developed to screen the title for eligibility. Intuitive data analysis was employed to analyze the top-100 cited articles and VOSViewer was used to analyze the relevance and impact of all articles. The two analysis methods were then compared to get conclusions.
    Results: The search identified 3,312 articles. In the end, 2,392 papers were included in the study, which were published between 1985 and 2023. All articles were analyzed using VOSViewer. Key points of the analysis included the co-authorship map of authors, countries and organizations, the citation map of journal and documents and a visualization of keyword co-occurrence analysis. Among these 100 top-cited papers, with a mean of 122.9 citations, the most-cited article had 1,189, and the least cited article had 47. Harvard University and the University of California topped the list among all institutes with 10 papers each. More than one-ninth of the authors of these 100 top-cited papers wrote three or more articles. The 100 articles came from 49 journals. The articles were divided into seven areas according to the type of machine learning approach employed: Support Vector Machines, Convolutional Neural Networks, Logistic Regression, Recurrent Neural Networks, Random Forest, Naive Bayes, and Decision Tree. Support Vector Machines were the most popular method.
    Conclusions: This analysis provides a comprehensive overview of the artificial intelligence (AI)-related research conducted in the field of heart failure, which helps healthcare institutions and researchers better understand the prospects of AI in heart failure and formulate more scientific and effective research plans. In addition, our bibliometric evaluation can assist healthcare institutions and researchers in determining the advantages, sustainability, risks, and potential impacts of AI technology in heart failure.

    Xiao-Fei Tong, Zhen-Yang Xiao, Pei-Ting Li, Xin Liu, Ming-Zhu Wang, Shi-Yi Wen, Na Wang, Shenghui Liao, Jian-Da Zhou.
      Adequate blood supply, a prerequisite for flap survival after grafting, makes angiogenesis of the flap the biggest problem to be solved. Researches have been conducted around vascularisation in correlation with flap grafting. However, bibliometric analyses systematically examining this research field are lacking. As such, we herein sought to conduct comprehensive comparative analyses of the contributions of different researchers, institutions, and countries to this research space in an effort to identify trends and hotspots in angiogenesis and vascularisation in the context of flap grafting. Publications pertaining to angiogenesis and vascularisation in the context of flap grafting were retrieved from the Web of Science Core Collection. References were then analysed and plotted using Microsoft Excel 2019, VOSviewer, and CiteSpace V. In total, 2234 papers that were cited 40 048 times (17.63 citations/paper) were included in this analysis. The greatest number of studies were from the United States, with these studies exhibiting both the highest number of citations (13 577) and the greatest overall H-index (60). For The institutions that published the greatest number of studies were WENZHOU MEDICAL UNIVERSITY (681), while UNIVERSITY OF ERLANGEN NUREMBERG has the highest number of citations (1458), and SHANGHAI JIAO TONG UNIVERSITY holds the greatest overall H-index (20). The greatest number of studies in this research space were published by Gao WY, while Horch RE was the most commonly cited researcher in the field. The VOS viewer software clustered relevant keywords into three clusters, with clusters 1, 2, 3, and 4 corresponding to studies in which the keywords 'anatomy', 'survival', 'transplantation', 'therapy' most frequently appeared. The most promising research hotspot-related terms in this field included 'autophagy', 'oxidative stress', 'ischemia/reperfusion injury', which exhibited a most recent average appearing year (AAY) of 2017 and after. Generally speaking, the results of this analysis indicate that the number of articles exploring angiogenesis and flap-related research has risen steadily, with the United States and China being the two countries publishing the greatest proportion of studies in this field. The overall focus of these studies has shifted away from 'infratest and tissue engineering' towards 'mechanisms'. In the future, particular attention should be paid to emerging research hotspots, which include 'ischemia/reperfusion injury' and treatments for promoting vascularization, such as 'platelet-rich plasma'. In light of these findings, funding agencies should continue increasing their investment in the exploration of the concrete mechanisms and interventional therapeutic relevance of angiogenesis during flap transplantation.

    Research trends and hotspots of post-stroke cognitive impairment: a bibliometric analysis.
    Xiansu Chi, Xueming Fan, Guojing Fu, Yue Liu, Yunling Zhang, Wei Shen.
      Background: Post-stroke cognitive impairment (PSCI) is a major complication of stroke that affects more than one-third of stroke survivors, threatening their quality of life and increasing the risk of disability and death. Although various studies have described the etiology, epidemiology, and risk factors of PSCI, there are a limited number of comprehensive and accurate reports on research trends and hotspots in this field. Therefore, this review aimed to evaluate research trends, hotspots, and frontiers in PSCI using bibliometric analysis. Methods: We screened the literature spanning 20 years in the Web of Science Core Collection: Science Citation Index Expanded (SCI-Expanded) database from 1 January 2003 to 31 December 2022. We included all eligible literature reports based on our comprehensive search strategy, inclusion criteria, and exclusion criteria. The analysis of annual publications, countries/regions, institutions, journals, co-cited references, and keywords was conducted using CiteSpace and VOSviewer, and the hotspots and major findings of PSCI were summarized. Results: A total of 1,024 publications were included in this review. We found that the number of publications on PSCI increased annually. These publications were published in 75 countries or regions by over 400 institutions. Although Chinese institutions had the highest number of publications, their international influence was limited. The United States showed a strong influence in the field. The journal "Stroke" published the most publications (57) with a high impact factor and was considered the most co-cited journal. The most frequently cited references focused on the prevalence, incidence, neuropsychological assessment scales, criteria, and guidelines of PSCI. The strongest citation burst keywords for PSCI were "neurotrophic factor" and "synaptic plasticity", which were regarded as research focuses and research hotspots, respectively. Conclusion: This review provided a comprehensive summary of the literature of PSCI, identified the authoritative and frequently cited literature and journals, clarified the trends in PSCI research, and highlighted the hotspots in this field. Currently, studies on the mechanisms and treatment of PSCI are limited, and we hope that this review has effectively highlighted the research trajectory of PSCI and will lay the foundation for more innovative research in the future.

    Deciphering the Influence of Estradiol and Estrogen Receptors on Cognitive Function: A Bibliometric Analysis and Emerging Research Trends.
    Min Wu, Shujie Lou.
      BACKGROUND The cognitive impact of estradiol (E2), a sex steroid hormone, particularly its unique characteristics mediated through different estrogen receptors (ERs), is garnering research interest to optimize estrogen replacement therapy (ERT) and mitigate adverse effects. However, a systematic bibliometric investigation elucidating the connection between E2/ERs and cognition is lacking. This study examines 3502 Web of Science Core Collection publications using CiteSpace to unveil trends in this research field. MATERIAL AND METHODS The primary goal was to analyze highly co-cited articles characterized by extensive citation, centrality, Sigma index, and burst strength. We identified six research themes and directions from ten distinct, highly credible clusters (Q=0.8266; S=0.978), established by frequently employed keywords. Secondly, we sought to highlight the most contributing countries, institutions, and authors in this domain. RESULTS The study unveiled that the 'critical age window period' hypothesis of ERT, hippocampus-derived E2, the mediating role of GPER, and crosstalk among ERs are the current hotspots in this field. Future research is likely to explore the links between E2/ERs and the hippocampus, various memory types, sex specificity, and receptor specificity. The United States and the University of Wisconsin have the most publications, while Scotland and Stanford University have the highest centrality. The most influential authors are Woolley CS, Frick KM, Tuscher JJ, and Espeland MA. CONCLUSIONS These findings inform prospective research directions and hint at potential E2 targets for cognitive enhancement.

    Disi Deng, Yifeng Shen, Wanjing Li, Nan Zeng, Yefang Huang, Xiaowei Nie.
       BACKGROUND: Human papillomavirus (HPV) vaccine has immense research value in the prevention of related tumours. A huge body of work has been published in this field, which may pose difficulties for researchers aiming to investigate all the available information. However, bibliometrics can provide deep insights into this research field.
    OBJECTIVE: We aimed to study HPV vaccine development, visually analyse the development status, trends, research hotspots, and frontiers of this field, and provide a reference for research on it.
    METHODS: Articles were acquired from the Web of Science Core Collection. VOS viewer and CiteSpace software were used to analyse publication growth, country/region, institution, journal distribution, author, reference, and keywords, and collected burst keyword words to display research hotspots.
    RESULTS: A total of 4831 references were obtained, and the annual number of publications increased fluctuating over the past decade. The United States of America ranked at the top in terms of percentage of articles. The institution with the highest number of research publications in this field was the Centers for Disease Control and Prevention. The most productive and frequently cited authors was Lauri E Markowitz. The journal with the most publications in this field was Vaccine, and the most influential journal was Paediatrics. The most frequently cited reference was 'A 9-Valent HPV Vaccine against Infection and Intraepithelial Neoplasia in Women'. Burst detection analysis of top keywords showed that 'national immunisation survey', 'social media', and 'hesitancy' are the current research frontiers in this field.
    CONCLUSION: This study provides useful information for acquiring knowledge on HPV vaccine. Research on solving the hesitation of HPV vaccination will become an academic trend in this field, which can offer guidance for more extensive and in-depth studies in the future.

    Dermatology Journals from India: A critical appraisal of the journal metrics.
    Hitaishi Mehta, Anuradha Bishnoi, Keshavamurthy Vinay, Sunil Dogra.
      Background Bibliometrics refer to documents and citation-based measures that measure different aspects of performance of a journal, including impact, output and prestige. Objective The aim of this study was to collect bibliometric data of various Indian dermatology journals as well as Indian journals from other disciplines, in order to compare relative performances. Methods Journal metrics pertaining to various Indian journals, both from dermatology [Indian Journal of Dermatology, Venereology and Leprology (IJDVL), Indian Journal of Dermatology (IJD), Indian Dermatology Online Journal, Indian Journal of Pediatric Dermatology and International Journal of Trichology] and other disciplines [Indian Journal of Medical Research (IJMR), Indian Journal of Pediatrics (IJP), Indian Journal of Ophthalmology and Indian Journal of Pharmacology] were sought. Data pertaining to the following 8 metrics during the year 2021 was collected: Journal Impact factor, SCImago Journal Rank, h5-index, Eigenfactor score and normalized Eigenfactor Score, Journal Citation Indicator, Scimago Journal and Country Rank H-index, CiteScore and Source Normalized Impact per Paper. Results Among Indian dermatology journals, for the year 2021, IJDVL had the highest impact factor (2.217) and h-index (48). IJD led in terms of prestige metrics such as SCImago Journal Rank (0.403), Eigenfactor score (0.00231) and Source Normalized Impact per Paper (1.132). IJDVL underperformed with respect to an average dermatology journal on all three prestige metrics. Among selected journals from other disciplines, two (IJMR and IJP) had impact factor exceeding five, despite lagging behind IJDVL two years ago. Most had normalized scores exceeding 1, indicating better performance than an average journal from their respective fields. Limitation Non-inclusion of altmetrics related data Conclusion IJDVL is one of the leading Indian journals in the field of dermatology, followed closely by IJD. A rise in IJDVL influence is evident over the past decade, as evident by various metrics. However, the progress still trails behind the average of global dermatology journals as evident by the field-normalized journal metrics, indicating potential for further growth of journal influence.

    Global status and research trends of cuprotosis research: A bibliometrics study via CiteSpace.
    Xiaoli Xie, Li Liu.
      Cuproptosis, a novel copper ion-dependent cell death type being regulated in cells, has raised concerns but lacks scientific analysis. Therefore, this study aimed to analyze the global status and emerging trends in cuprotosis research using bibliometric methods. Publications related to cuprotosis were systematically retrieved from the Web of Science Core Collection and then screened according to the inclusion criteria. Next, CiteSpace and Microsoft Excel 2021 were used to measure and visualize annual publications, categories, journals, countries, institutions, authors, co-cited references, and keywords to identify future global status and trends. A total of 2776 publications on cuprotosis were included, and the overall trend in the number of publications exhibited a rapid increase over the years. Biochemistry and Molecular Biology is the most common category, whereas the Journal of Inorganic Biochemistry is the most active. The United States is the country that produces the most articles, and University of Melbourne in Australia is the core institution involved in this field. Furthermore, Chan Pak of Stanford University is the most prolific author. Oxidative stress and antioxidant, the toxicity of copper in vitro, anticancer mechanism, and brain injury in neurological diseases are hot topics. The research frontiers are copper complexes, anticancer activity, DeoxyriboNucleic Acid binding, inflammation, and nanoparticles. This study provides the current status and trends in cuprotosis research. It may help researchers to identify hot topics and get ideas for future research directions in this field, focusing on copper complexes, anticancer activity, DeoxyriboNucleic Acid binding, inflammation, and nanoparticles.

    Global research trends on immunotherapy in cancer: A bibliometric analysis.
    Zhichao Yao, Zhiyong Lin, Weijia Wu.
      Cancer immunotherapy has been gradually introduced and has undergone noteworthy developments in recent years. The number of scientific publications has been expanding, and the progression in this field has been rapidly evolving with time. This study aimed to use bibliometric analysis to examine the past 20 years of research on cancer immunotherapy and identify future hotspots. A literature search for medical publications on immunotherapy in cancer from 2000 to 2021 was conducted in the Web of Science Core Collection on March 1, 2022. Visualization analysis was performed using VOSviewer software (version 1.6.16). From 2000 to 2021, a total of 18,778 publications were retrieved. Annual publication output grew rapidly from 366 in 2000 to 3,194 in 2021. The USA issued the largest number of publications (n = 6,739, 35.89%), with the University of Texas System making the largest contribution (n = 802, 4.27%). A total of 976 meaningful topics were identified and further classified into 4 different clusters (immune mechanism, cancer biology, immunotherapy and clinical trials). The most common research topics included 'expression', 'chemotherapy', 'dendritic cells', 'pembrolizumab' and 'open-label'. Highly identified cancer types included hepatocellular, bladder, breast and lung cancer. A shift in popularity from mechanism research to clinical trials was observed, indicating that clinical application would be the center of attention in the future. Attention has been given to the field of cancer immunotherapy, and this trend will continue in the future. This study provides an unbiased visualization analysis on this topic in a scale-efficient manner for further research.

    Trends and statistics of artificial intelligence and radiomics research in Radiology, Nuclear Medicine, and Medical Imaging: bibliometric analysis.
    Burak Kocak, Bettina Baessler, Renato Cuocolo, Nathaniel Mercaldo, Daniel Pinto Dos Santos.
       OBJECTIVE: To conduct a comprehensive bibliometric analysis of artificial intelligence (AI) and its subfields as well as radiomics in Radiology, Nuclear Medicine, and Medical Imaging (RNMMI).
    METHODS: Web of Science was queried for relevant publications in RNMMI and medicine along with their associated data from 2000 to 2021. Bibliometric techniques utilised were co-occurrence, co-authorship, citation burst, and thematic evolution analyses. Growth rate and doubling time were also estimated using log-linear regression analyses.
    RESULTS: According to the number of publications, RNMMI (11,209; 19.8%) was the most prominent category in medicine (56,734). USA (44.6%) and China (23.1%) were the two most productive and collaborative countries. USA and Germany experienced the strongest citation bursts. Thematic evolution has recently exhibited a significant shift toward deep learning. In all analyses, the annual number of publications and citations demonstrated exponential growth, with deep learning-based publications exhibiting the most prominent growth pattern. Estimated continuous growth rate, annual growth rate, and doubling time of the AI and machine learning publications in RNMMI were 26.1% (95% confidence interval [CI], 12.0-40.2%), 29.8% (95% CI, 12.7-49.5%), and 2.7 years (95% CI, 1.7-5.8), respectively. In the sensitivity analysis using data from the last 5 and 10 years, these estimates ranged from 47.6 to 51.1%, 61.0 to 66.7%, and 1.4 to 1.5 years.
    CONCLUSION: This study provides an overview of AI and radiomics research conducted mainly in RNMMI. These results may assist researchers, practitioners, policymakers, and organisations in gaining a better understanding of both the evolution of these fields and the importance of supporting (e.g., financial) these research activities.
    KEY POINTS: • In terms of the number of publications on AI and ML, Radiology, Nuclear Medicine, and Medical Imaging was the most prominent category compared to the other categories related to medicine (e.g., Health Policy & Services, Surgery). • All evaluated analyses (i.e., AI, its subfields, and radiomics), based on the annual number of publications and citations, demonstrated exponential growth, with decreasing doubling time, which indicates increasing interest from researchers, journals, and, in turn, the medical imaging community. • The most prominent growth pattern was observed in deep learning-based publications. However, the further thematic analysis demonstrated that deep learning has been underdeveloped but highly relevant to the medical imaging community.

    Jiali Yang, Jiaojiao Wu, Tingliang Han, Hua Lu, Fangcun Li, Leilei Li, Shaoting Su, Ping Jiang, Zhaomeng Hou.
      The objective of this study is to utilize bibliometric and visual analysis techniques to identify hotspots and frontiers of research in myasthenia gravis (MG) and provide valuable references for future research. The Web of Science Core Collection (WoSCC) database was used to retrieve literature data related to MG research, which was then analyzed using VOSviewer 1.6.18, CiteSpace 6.1.R3, and the Online Platform for Bibliometric Analysis. The analysis revealed 6734 publications distributed across 1612 journals and contributed by as many as 24,024 authors affiliated with 4708 institutions across 107 countries/regions. The number of annual publications and citations for MG research has steadily increased over the past 2 decades, with the last 2 years alone witnessing a remarkable increase in annual publications and citations to over 600 and 17,000, respectively. In terms of productivity, the United States emerged as the top producing country, while the University of Oxford ranked first in terms of research institutions. Vincent A was identified as the top contributor in terms of publications and citations. Muscle & Nerve and Neurology ranked first in publications and citations respectively, with clinical neurology and neurosciences among the main subject categories explored. The study also identified pathogenesis, eculizumab, thymic epithelial cells, immune checkpoint inhibitors, thymectomy, MuSK antibodies, risk, diagnosis, and management as the current hot research topics in MG, while burst keywords like quality of life, immune-related adverse events (irAEs), rituximab, safety, nivolumab, cancer, and classification indicated the frontiers of MG research. This study effectively identifies the hotspots and frontiers of MG research, and offers valuable references for researchers interested in this area.

    Faster, higher, stronger - together? A bibliometric analysis of author distribution in top medical education journals.
    Dawit Wondimagegn, Cynthia Ruth Whitehead, Carrie Cartmill, Eloy Rodrigues, Antónia Correia, Tiago Salessi Lins, Manuel João Costa.
       INTRODUCTION: Medical education and medical education research are growing industries that have become increasingly globalised. Recognition of the colonial foundations of medical education has led to a growing focus on issues of equity, absence and marginalisation. One area of absence that has been underexplored is that of published voices from low-income and middle-income countries. We undertook a bibliometric analysis of five top medical education journals to determine which countries were absent and which countries were represented in prestigious first and last authorship positions.
    METHODS: Web of Science was searched for all articles and reviews published between 2012 and 2021 within Academic Medicine, Medical Education, Advances in Health Sciences Education, Medical Teacher, and BMC Medical Education. Country of origin was identified for first and last author of each publication, and the number of publications originating from each country was counted.
    RESULTS: Our analysis revealed a dominance of first and last authors from five countries: USA, Canada, UK, Netherlands and Australia. Authors from these five countries had first or last authored 70% of publications. Of the 195 countries in the world, 43% (approximately 83) were not represented by a single publication. There was an increase in the percentage of publications from outside of these five countries from 23% in 2012 to 40% in 2021.
    CONCLUSION: The dominance of wealthy nations within spaces that claim to be international is a finding that requires attention. We draw on analogies from modern Olympic sport and our own collaborative research process to show how academic publishing continues to be a colonised space that advantages those from wealthy and English-speaking countries.

    Artificial intelligence in acupuncture: A bibliometric study.
    Qiongyang Zhou, Tianyu Zhao, Kaidi Feng, Rui Gong, Yuhui Wang, Huijun Yang.
      This study aimed to provide a panorama of artificial intelligence (AI) in acupuncture by characterizing and visualizing the knowledge structure, hotspots and trends in global scientific publications. Publications were extracted from the Web of Science. Analyses on the number of publications, countries, institutions, authors, co-authorship, co-citation and co-occurrence were conducted. The USA had the highest volume of publications. Harvard University had the most publications among institutions. Dey P was the most productive author, while lczkowski KA was the most referenced author. The Journal of Alternative and Complementary Medicine was the most active journal. The primary topics in this field concerned the use of AI in various aspects of acupuncture. "Machine learning" and "deep learning" were speculated to be potential hotspots in acupuncture-related AI research. In conclusion, research on AI in acupuncture has advanced significantly over the last two decades. The USA and China both contribute significantly to this field. Current research efforts are concentrated on the application of AI in acupuncture. Our findings imply that the use of deep learning and machine learning in acupuncture will remain a focus of research in the coming years.

    Bibliometric analysis of research topics on blood-brain barrier breakdown and cognitive function over the last two decades (2000-2021).
    Ruirui Zhang, Yiqi Zhang, Tong Wu, Weitian Tian, Jiamei Luo, Yumiao Shi, Diansan Su, Huigang Shu, Jie Tian.
       Introduction: Blood-brain barrier (BBB) breakdown is closely associated with cognitive dysfunction. This study aimed to categorize and summarize research topics on the correlation between BBB breakdown and its effects on cognitive function.
    Methods: Bibliometric analysis methods were used to quantitatively and qualitatively assess research progress and predict future research hotspots. Relevant publications from the Web of the Science Core Collection were extracted on November 5, 2022 and analyzed to predict trends and hotspots in the field.
    Results: We identified 5518 articles published from 2000 to 2021 about the BBB and cognition. The number of manuscripts on this topic increased steadily during this time period, especially after 2013. We found that the number of articles published in China increased gradually and is in second place behind the United States of America (USA). In the research field of BBB breakdown and cognitive function, the USA is still far ahead. Keyword burst detection suggested that cognitive impairment, neurodegeneration disease and neuroinflammation are emerging research hotspots.
    Discussion: The mechanisms of BBB integrity breakdown and its effects on the deterioration of cognitive function are complex, and clinical treatment of the affected diseases has been a hot topic in the field over the past 22 years. Looking forward, this body of research is aimed at improving or maintaining patients' cognitive abilities, by finding preventive measures and to provide a basis for finding new treatments of cognitive disorders.

       Introduction: Bibliometrics is a quantitative analytic strategy used to assess the unit of publications per each field of research. Bibliometric studies are commonly employed to examine the current research climate, potential developments, and development trends in certain domains. In this work, the major contributors to camel research throughout the past century are discussed, along with the funding sources, academic institutions, scientific disciplines, and countries that contributed to "Camel Research".
    Methods: The Web of Science (WOS) database was used to retrieve the publications based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) instructions.
    Results: There are 7,593 articles dedicated to camel research on the Web of Science (as of August 1st, 2022). Three stages were involved in the publication of a study on camels. At the beginning, from 1877 to 1965, there were fewer than ten new publications per year. The second stage comprised 100 publications per year (1968-2005). Since 2010, nearly 200 new papers have been published each year. King Saud and King Faisal universities contributed > (0.08) of the total publications. While more than 1,000 funding agents were retrieved, the Natural Science Foundation of China (NSFC) showed the greatest rate of funded projects (0.17). Camel research was included in 238 scientific disciplines. The top disciplines were Veterinary Sciences (0.39), Agriculture Dairy Animal Science (0.144), and Food Science Technology (0.087).
    Conclusion: There has been an increase in interest in camels in recent years, but the research trends in camel health and production need greater support.

    Women authorship in pain research: A bibliometric analysis from 2002 to 2021.
    Haoyan Zhong, Jashvant Poeran, Crispiana Cozowicz, Alex Illescas, Jiabin Liu, Stavros G Memtsoudis.
       OBJECTIVES: There is a lack of data on the distribution of women first and senior authorships in pain journals. Using articles published in top North American pain journals over the past two decades, we sought to describe the prevalence and changes in women representation among first and last authors.
    METHODS: We retrieved all published research articles in four pain journals (Regional Anesthesia and Pain Medicine, Clinical Journal of Pain, Pain and The Journal of Pain) from 2002 to 2021 using the easyPubMed package. Subsequently, the 'gender' package in R was used to determine authors' gender by first names. Trends in gender authorship change over time were assessed.
    RESULTS: The final cohort consisted of 20,981 authors (from an initial total of 11,842 publications and 23,684 authors retrieved). Women authors were more often first compared to senior authors (46.7% vs. 30.5%). The proportion of women first authors (46.2% in 2002 vs. 48.4% in 2021) and women senior authors (22.4% in 2002 vs. 36.3% in 2021) increased over the course of the study period (all p-value <0.001). The Clinical Journal of Pain having the highest percentage of women authors and Regional Anesthesia and Pain Medicine had the lowest percentage of women authors.
    DISCUSSION: Our data demonstrated increasing women authorship in pain journals in the past 20 years, largely driven by an increase in first authorships. There still remains a large gap between first and senior authorship, indicative of disparity in the role that women play in research.

       Background: Alzheimer's disease (AD) is a common, progressive, irreversible, and fatal neurodegenerative disorder with rapidly increasing worldwide incidence. Although much research on magnetic resonance imaging (MRI) of the white matter (WM) in AD has been published, no bibliometric analysis study has investigated this issue. Thus, this study aimed to provide an overview of the current status, hotspots, and trends in MRI of WM in AD.
    Methods: We searched for records related to MRI studies of WM in AD from 1990 to 2022 in the Web of Science Core Collection (WOSCC) database. CiteSpace (version 5.1.R8) and VOSviewer (version 1.6.19) software were used for bibliometric analyses.
    Results: A total of 2,199 articles were obtained from this study. From 1990 to 2022, the number of published articles showed exponential growth of y = 4.1374e0.1294x, with an average of 17.9 articles per year. The top country and institutions were the United States and the University of California Davis, accounting for 44.52 and 5.32% of the total studies, respectively.

    Mapping the field of microalgae CO2 sequestration: a bibliometric analysis.
    Hongyan Ren, Duan Zhou, Jiawen Lu, Pau Loke Show, Fubao Fuelbiol Sun.
      Microalgae CO2 sequestration has gained considerable attention in the last three decades as a promising technology to slow global warming caused by CO2 emissions. To provide a comprehensive and objective analysis of the research status, hot spots, and frontiers of CO2 fixation by microalgae, a bibliometric approach was recently chosen for review. In this study, 1561 articles (1991-2022) from the Web of Science (WOS) on microalgae CO2 sequestration were screened. A knowledge map of the domain was presented using VOSviewer and CiteSpace. It visually demonstrates the most productive journals (Bioresource Technology), countries (China and USA), funding sources, and top contributors (Cheng J, Chang JS, and their team) in the field of CO2 sequestration by microalgae. The analysis also revealed that research hotspots changed over time and that recent research has focused heavily on improving carbon sequestration efficiency. Finally, commercialization of carbon fixation by microalgae is a key hurdle, and supports from other disciplines could improve carbon sequestration efficiency.

    Samantha Harrer, Justin A Magnuson, Gregory R Toci, Andrew M Star, Arjun Saxena.
       INTRODUCTION: Postoperative dislocation of unclear etiology remains a concern after total hip arthroplasty (THA). Interest is growing in the importance of spinopelvic alignment on stability in THA. The purpose of this study was to analyze publication trends, areas of interest, and future research direction of spinopelvic alignment in THA.
    METHODS: Articles on the topic of spinopelvic alignment in THA published between 1990 and 2022 were obtained through Web of Science Core Collection of Clarivate Analytics (WSCCA). Results were screened by title, abstract, and full text. The inclusion criterion was English-language peer-reviewed journal publications on the clinical topic of spinopelvic alignment in THA. Bibliometric software was used to characterize publication trends.
    RESULTS: We screened 1,211 articles, yielding 132 meeting the inclusion criterion. From 1990 to 2022, published articles have steadily increased, peaking in 2021. Countries that have been the most productive in contributions to research are those in which THA is the most prevalent. Our analysis of keyword frequency showed increasing interest in "pelvic tilt," "anteversion," and "acetabular component" position.
    CONCLUSION: Our study identified that increasing attention is being given to spinopelvic mobility and PT in the setting of THA. The United States and France produced the most studies related to spinopelvic alignment.

    "Bringing in" and "Going abroad": A bibliometric evaluation of the internationalization of archaeology in Mainland China.
    Xuan Wei, Wentai Lou, Ting Li, Ruxi Yang, Yinghua Li.
      Chinese scholars' performance in international academic community and research on foreign archaeology has brought hot discussion about the internationalization of Chinese archaeology. Based on the databases of the China National Knowledge Infrastructure (CNKI) and the Web of Science core collection (WoS), this paper collected archaeology-related papers published by Chinese scholars in Chinese and world core journals (CCJs and WCJs for short), then filtered translated and original articles about foreign archaeology in CCJs, as well as all original archaeological articles in WCJs. Using Excel, CiteSpace and VOSviewer visualization software, we analyzed these data to give a bird's-eye view of how archaeology research in Mainland China has become internationalized. Chinese archaeology has seen active-interrupt-active phases characterized by learning from foreign academics in the last century. Over the past two decades, the number of articles published in WCJs by scholars from Mainland China has increased significantly, and most research topics are at the forefront of international scholarship. Collaboration networks largely expanded, with the number of Mainland China-led articles increasing significantly. Archaeological papers written by researchers from Mainland China have appeared in a more extensive range of journals, including those with high impact factors. However, articles related to joint Sino-foreign archaeological projects were mostly published in CCJs. The archaeology-related articles published by Chinese scholars in WCJs occupied only a small proportion of all archaeological articles in WCJs. Compared to articles in CCJs, the number of those published by Chinese scholars in WCJs is a drop in the ocean. Therefore the internationalization is not yet a dominant trend and with the introduction of the new inward-looking policy we need more time to observe where the trends of internationalization and localization in Chinese archaeology are heading.

    Eighteen Years of Medical Oncology in Morocco: A Bibliometric Evaluation.
    Mohamed Kaakoua, Aboubaker Boufdil, Mohammed El Fadli, Rhizlane Belbaraka, Ismail Essadi.
      Medical publications constitute an essential tool for sharing scientific advances in the medical field. They are also an educational tool of great significance in initial medical training, and also in further medical education. These publications are necessary to ensure an interface between the researchers and members of the medical scientific community, who are always looking for the correct and optimal treatment for their patients. Several golden rules have been laid out in terms of assessing the improvement in scientific productivity, namely the quality of the subject, the type of publication, the publication review and its impact factor, and the establishment of international collaborations. Bibliometrics is a quantitative and qualitative analysis of scientific publications, which aids in assessing the scientific productivity of a community or a scientific institution. To the best of our knowledge, this is the first bibliometric study to evaluate the scientific productivity in the field of medical oncology in Morocco.

    Trends in Global Research for Treating Intracranial Aneurysms: A Bibliographic Analysis.
    Allen Ye Fu, Siddhant Kumarapuram, Sanjeev Sreenivasan, Sudipta Roychowdhury, Gaurav Gupta.
       INTRODUCTION: Although significant advancements have been made in the detection, surveillance, and treatment of intracranial aneurysms, research and care can differ vastly based on location. Currently, there is a lack of knowledge regarding the trends in the literature and how the field is evolving with new technology.
    OBJECTIVE: Here, we use bibliographic analysis to visualize the knowledge structure of the field and identify global research trends in intracranial aneurysm treatment.
    METHODS: The Web of Science Core Collection was queried for primary research and review articles related to intracranial aneurysm treatment. 4,702 relevant documents were collected and publications over time on different treatment types and publications and citations of journals were collected. VOSviewer was used to: 1) identify relationships between keywords, 2) identify co-authorship patterns among organizations and countries, and 3) analyze citation patterns of countries, organizations, and journals.
    RESULTS: Our results show that research in flow diversion increased at a rapid rate but tended to have low link strength with keywords related to evaluating patient risk and mortality. The highest publication producing countries were the USA, Japan, and China, although China had less citations relative to its peers. Korean organizations showed less international collaboration. The USA has been the leader in terms of productivity and collaboration in the field, as have several US-based journals such as Journal of Neurosurgery, Neurosurgery, and World Neurosurgery.
    CONCLUSION: Evaluating the safety of flow diversion treatment remains a pressing area of research. Chinese and Korean organizations may be of interest for global collaborations.

    Knowledge mapping of UMOD of English published work from 1985 to 2022: a bibliometric analysis.
    Guannan Sun, Chao Liu, Chengcheng Song, Xiaodong Geng, Kun Chi, Zhangning Fu, Quan Hong, Di Wu.
       BACKGROUND: UMOD is exclusively produced by renal epithelial cells. Recent genome-wide association studies (GWAS) suggested that common variants in UMOD gene are closely connected with the risk of CKD. However, a comprehensive and objective report on the current status of UMOD research is lacking. Therefore, we aim to conduct a bibliometric analysis to quantify and identify the status quo and trending issues of UMOD research in the past.
    METHODS: We collected data from the Web of Science Core Collection database and used the Online Analysis Platform of Literature Metrology, the Online Analysis Platform of Literature Metrology and Microsoft Excel 2019 to perform bibliometricanalysis and visualization.
    RESULTS: Based on the data from the WoSCC database from 1985 to 2022, a total of 353 UMOD articles were published in 193 academic journals by 2346 authors from 50 different countries/regions and 396 institutions. The United States published the most papers. Professor Devuyst O from University of Zurich not only published the greatest number of UMOD-related papers but also is among the top 10 co-cited authors. KIDNEY INTERNATIONAL published the most necroptosis studies, and it was also the most cited journal. High-frequency keywords mainly included 'chronic kidney disease', 'Tamm Horsfall protein' and 'mutation'.
    CONCLUSIONS: The number of UMOD-related articles has steadily increased over the past decades Current UMOD studies focused on Biological relevance of the UMOD to kidney function and potential applications in the risk of CKD mechanisms, these might provide ideas for further research in the UMOD field.

    A bibliometric and content analysis of Best Practices in School Psychology.
    Randy G Floyd, Sequoya A Fitzpatrick, Patrick J McNicholas, Nikita M Pike.
      Best Practices in School Psychology is one of the most influential books in school psychology history. Originally published in 1985 by Thomas and Grimes, it was the first book offered by the National Association of School Psychologists. Its six editions have been revised every 5-8 years. Utilizing Publish or Perish as well as cross-referenced tables of contents from Best Practices, a bibliometric analysis of its 589 chapters and 37 appendices was completed. Results yielded 15,812 citations in Google Scholar-most citations (6,448) stem from its fourth edition, published in 2002. One chapter by Good et al. (2002) was cited more than 400 times, and five other chapters were cited more than 300 times. In all, 42 chapters were cited more than 100 times. Content analysis revealed that most chapters primarily addressed domains reflecting data-based decision making and interventions. The 79 most cited chapters generated almost two-thirds of all citations, and at least one-third of the citations to each of the 10 most cited chapters emerged from student projects, such as theses and dissertations. The editors, authors, and reviewers of Best Practices have produced a massive number of chapters across six editions, and although these publications were initially intended to guide practicing school psychologists, they have had a substantial impact on scholarship, including student projects.

    Citation Cartels in Medical and Dental Journals.
    Syed Jaffar Abbas Zaidi, Muhammad Taqi.
      Citation cartels are groups of researchers who excessively cite each other's work to artificially inflate their citation counts and enhance their reputation. The practice of the citation cartel involves journals agreeing to cite each other's publications to boost their own impact factors. The citation cartel has been criticised for distorting the impact factors of participating journals and undermining the integrity of the scientific process. Citation cartels can take many forms, including reciprocal citing, where researchers agree to cite each other's work in exchange for citations. Citation cartels often involve a small group of researchers who are closely connected and who may be deliberately hiding their activities. To combat citation cartels, journals should use software tools to identify patterns of suspicious citing behaviour and should implement policies that encourage transparency and discourage self-citation. Journals should be held accountable for unethical citation practices, and researchers should carefully evaluate before submission. Key Words: Citation, Citation index, Self-citation, Impact factor.

    Gender and Research Productivity of Vitreoretinal Surgery Fellowship Program Directors.
    John C Lin, Anagha Lokhande, Ingrid U Scott, Paul B Greenberg.
       BACKGROUND AND OBJECTIVE: Characteristics of vitreoretinal surgery fellowship program directors (PDs) in North America are not well described. This study reports on the gender and research productivity of vitreoretinal surgery PDs in the United States and Canada.
    MATERIALS AND METHODS: We reviewed demographics, total number of Scopus-indexed publications, h-index, and m-quotient for vitreoretinal surgery fellowship PDs in 2022. Descriptive statistics, student t-tests, χ2 tests, and logistic regression analyses were performed.
    RESULTS: Information was obtained on 83/89 (93%) PDs; 86% were male, and 84% did not have an additional graduate degree. The mean publication count was 81.54 (SD: 90.33) and mean h-index was 20.61 (SD: 16.49). There were no significant differences between female and male fellowship PDs with respect to number of publications, h-indices, and m-quotients.
    CONCLUSION: Women were underrepresented among vitreoretinal fellowship PDs although they had similar research productivity as their male colleagues. [Ophthalmic Surg Lasers Imaging Retina 2023;54:xx-xx.].

    Talent identification research: a bibliometric study from multidisciplinary and global perspectives.
    Fabio Andres Parra-Martinez, Jonathan Wai.
      This paper describes the general status, trends, and evolution of research on talent identification across multiple fields globally over the last 80 years. Using Scopus and Web of Science databases, we explored patterns of productivity, collaboration, and knowledge structures in talent identification (TI) research. Bibliometric analysis of 2,502 documents revealed talent identification research is concentrated in the fields of management, business, and leadership (~37%), sports and sports science (~20%), and education, psychology, and STEM (~23%). Whereas research in management and sports science has occurred independently, research in psychology and education has created a bridge for the pollination of ideas across fields. Thematic evolution analysis indicates that TI has well developed motor and basic research themes focused on assessment, cognitive abilities, fitness, and youth characteristics. Motor themes in management and sports science bring attention to talent management beyond TI. Emerging research focuses on equity and diversity as well as innovation in identification and technology-based selection methods. Our paper contributes to the development of the body of TI research by (a) highlighting the role of TI across multiple disciplines, (b) determining the most impactful sources and authors in TI research, and (c) tracing the evolution of TI research which identifies gaps and future opportunities for exploring and developing TI research and its broader implications for other areas of research and society.

    The Value of Case Reports in Plastic Surgery: An Analysis of 68,444 Articles across Six Major Plastic Surgery Journals.
    Benjamin H Ormseth, Benjamin A Sarac, Tormod S Westvik, Jeffrey E Janis.
      Case reports provide a salient contribution to the field of plastic surgery through the timely dissemination of knowledge on previously underreported topics. Once a time-honored hallmark of the surgical literature, the perceived value of case reports has decreased with the ongoing prioritization of higher levels of evidence. In this study, we aimed to assess long-term trends in case report publication rates and discuss the continued merits of case reports in the modern-day landscape.
    Methods: A PubMed search was used to identify articles published in six prominent plastic surgery journals since 1980. Articles were separated as case reports versus all other publication types. The total number of articles published by group was tracked, and citation rates were compared across groups. Additionally, the most cited articles from each journal were identified for both groups.
    Results: A total of 68,444 articles were included for analysis. In 1980, there were 181 case reports published compared with 413 other articles across all six journals. In 2022, there were 188 case reports published compared with 3343 other articles. When comparing citations per year of case reports versus other article types across all journals since 1980, case reports were found to be cited significantly less frequently (P < 0.001).
    Conclusions: Case reports have been published and cited less frequently than other types of literature over the last 42 years. However, despite these trends, they have demonstrated significant historical contributions and provide continued value as an impactful forum for highlighting novel clinical entities.

    Evolution of retracted publications in the medical sciences: Citations analysis, bibliometrics, and altmetrics trends.
    Shahnaz Khademizadeh, Farshid Danesh, Samira Esmaeili, Brady Lund, Karen Santos-d'Amorim.
      We investigated reasons for retraction, pre-and post-retraction citations and Altmetrics indicators of retracted publications in the medical sciences from 2016 to 2020. Data were retrieved from Scopus (n = 840). The Retraction Watch database was used to identify the reasons for retraction and the time that elapsed from publication to retraction. The findings showed that intentional errors were the most prevalent reasons for retraction. China (438), the United States (130), and India (51) have the largest share of retractions. These retracted publications were cited 5,659 times in other research publications, of which 1,559 citations occurred after the retraction, which should raise concern. These retracted papers were also shared in online platforms, mainly on Twitter and by members of the general public. We recommend that the early detection of retracted papers may help to reduce the rate of citation and sharing of these publications, and minimize their negative impact.

    Bibliometric and visualized analysis of drug resistance in ovarian cancer from 2013 to 2022.
    Jiahua Liu, Junnan Ma, Jiarong Zhang, Chengming Li, Bowen Yu, Hyok Chol Choe, Kaiyue Ding, Liu Zhang, Lin Zhang.
       Objective: As one of the cancers that seriously threatens women's health, ovarian cancer has a high morbidity and mortality rate. Surgery and chemotherapy are the basic treatment strategies for ovarian cancer, and chemotherapy resistance is a significant factor in affecting the prognosis, survival cycle, and recurrence of ovarian cancer. This article aims to analyze articles about ovarian cancer and drug resistance via bibliometric software, offering new ideas and directions for researchers in this field.
    Methods: Both Citespace and Vosviewer are bibliometric software on the Java platform. Articles were collected on ovarian cancer and drug resistance in the Web of Science Core Collection database from 2013 to 2022. The countries, institutions, journals, authors, keywords, and references were analyzed, and the development status of this field was indicated from multiple perspectives.
    Results: Studies on ovarian cancer and drug resistance generally showed an increasing trend from 2013 to 2022. The People's Republic of China and Chinese institutions contributed more to this field. Gynecologic Oncology published the most articles, and the journal with the most citations was Cancer Research. Li Li was the author with the most publications, and Siegel RL was the author with the most citations. Through burst detection, it can be found that the research hotspots in this field mainly focused on the in-depth exploration of the drug resistance mechanism of ovarian cancer and the progress of PARP inhibitors and bevacizumab in the treatment of ovarian cancer.
    Conclusions: Many studies on the mechanism of drug resistance in ovarian cancer have been discovered; however, the deeper mechanism remains to be explored. Compared with traditional chemotherapy drugs, PARP inhibitors and bevacizumab have shown better efficacy, but PARP inhibitors have initially shown drug resistance. The future direction of this field should be to overcome the resistance of existing drugs and actively develop new ones.

    The impact of geographic inequality in federal research funding: A comparative longitudinal study of research and scholarly outputs in EPSCoR versus non-EPSCoR states.
    Ehsan Mohammadi, Anthony J Olejniczak, George E Walker, Prakash Nagarkatti.
      Some states in the U.S. have traditionally received less federal research funding than other states. The National Science Foundation (NSF) created a program in 1979, called the Experimental Program to Stimulate Competitive Research (EPSCoR) to enhance the research competitiveness in such states. While the geographic disparity in federal research funding is well known, the overall impact of federal funding on the research performance of EPSCoR and non-EPSCoR has not been previously studied. In the current study, we compared the combined research productivity of Ph.D. granting institutions in EPSCoR versus the non-EPSCoR states to better understand the scientific impact of federal investments in sponsored research across all states. The research outputs we measured included journal articles, books, conference papers, patents, and citation count in academic literature. Unsurprisingly, results indicated that the non-EPSCoR states received significantly more federal research funding than their EPSCoR counterparts, which correlated with a higher number of faculty members in the non-EPSCoR versus EPSCoR states. Also, in the overall research productivity expressed on a per capita, the non-EPSCoR states fared better than EPSCoR states. However, when the research output was measured based on per $1M investment of federal research funding, EPSCoR states performed significantly better than the non-EPSCoR states in many research productivity indicators, with the notable exception of patents. Together, this study found preliminary evidence that EPSCoR states achieved a high degree of research productivity despite receiving significantly fewer federal research dollars. The limitations and next steps of this study are also discussed.

    Research landscape of 3D printing in bone regeneration and bone repair: A bibliometric and visualized analysis from 2012 to 2022.
    Zhen Yang, Hao Li, Jianjing Lin, Dan Xing, Jiao Jiao Li, Elise M Cribbin, Alice M Kim, Zihao He, Hui Li, Weimin Guo, Licheng Zhang, Jianhao Lin.
      Three-dimensional printing (3DP) is a popular manufacturing technique with versatile potential for materials processing in tissue engineering and regenerative medicine. In particular, the repair and regeneration of significant bone defects remain as substantial clinical challenges that require biomaterial implants to maintain mechanical strength and porosity, which may be realized using 3DP. The rapid progress in 3DP development in the past decade warrants a bibliometric analysis to gain insights into its applications in bone tissue engineering (BTE). Here, we performed a comparative study using bibliometric methods for 3DP in bone repair and regeneration. A total of 2,025 articles were included, and the results showed an increase in the number of publications and relative research interest on 3DP annually worldwide. China was the leader in international cooperation in this field and also the largest contributor to the number of citations. The majority of articles in this field were published in the journal Biofabrication. Chen Y was the author who made the highest contribution to the included studies. The keywords included in the publications were mainly related to BTE and regenerative medicine (including "3DP techniques," "3DP materials," "bone regeneration strategies," and "bone disease therapeutics") for bone regeneration and repair. This bibliometric and visualized analysis provides significant insights into the historical development of 3DP in BTE from 2012 to 2022, which will be beneficial for scientists to conduct further investigations into this dynamic field.

    Global hotspots and emerging trends in 3D bioprinting research.
    Zhiyu Ding, Ning Tang, Junjie Huang, Xu Cao, Song Wu.
      Three-dimensional (3D) bioprinting is an advanced tissue engineering technique that has received a lot of interest in the past years. We aimed to highlight the characteristics of articles on 3D bioprinting, especially in terms of research hotspots and focus. Publications related to 3D bioprinting from 2007 to 2022 were acquired from the Web of Science Core Collection database. We have used VOSviewer, CiteSpace, and R-bibliometrix to perform various analyses on 3,327 published articles. The number of annual publications is increasing globally, a trend expected to continue. The United States and China were the most productive countries with the closest cooperation and the most research and development investment funds in this field. Harvard Medical School and Tsinghua University are the top-ranked institutions in the United States and China, respectively. Dr. Anthony Atala and Dr. Ali Khademhosseini, the most productive researchers in 3D bioprinting, may provide cooperation opportunities for interested researchers. Tissue Engineering Part A contributed the largest publication number, while Frontiers in Bioengineering and Biotechnology was the most attractive journal with the most potential. As for the keywords in 3D bioprinting, Bio-ink, Hydrogels (especially GelMA and Gelatin), Scaffold (especially decellularized extracellular matrix), extrusion-based bioprinting, tissue engineering, and in vitro models (organoids particularly) are research hotspots analyzed in the current study. Specifically, the research topics "new bio-ink investigation," "modification of extrusion-based bioprinting for cell viability and vascularization," "application of 3D bioprinting in organoids and in vitro model" and "research in personalized and regenerative medicine" were predicted to be hotspots for future research.

    Trends in women's representation as lead authors in high impact journals of lung cancer.
    Ni Dai, Junqiang Li, Lixia Ren.
       Background: Women's participation in the clinical oncology practice has increased over the past decade. There is a need to investigate whether women's participation in academia, as reflected by publication activity, increased over the time. This study aimed to investigate trends in female authorship in top journals of lung cancer in the past ten years.
    Methods: In this cross-sectional study of all original research and review articles published in lung cancer journals including New England Journal of Medicine, Lancet journals, JAMA journals, Journal of Clinical Oncology, Annals of Oncology, Cancer Discovery, Journal of Thoracic Oncology, and Translational Lung Cancer Research (TLCR) between 2012 and 2021, the sex composition of lead authors were analyzed. The sex of the author was confirmed by internet searching for photographs, biographies, and gender-specific pronouns from journal or personal websites. The time-trend of female authorship was determined using Join-Point Regression (JPR) analysis.
    Results: A total of 3,625 first authors and 3,612 corresponding authors were identified in the journals during the years studied. The sex of the author was revealed for 98.5%. Among 3,625 first authors with the sex being revealed, 1,224 (33.7%) were women. The proportion of female first authors increased remarkably from 29.4% in 2012 to 39.8% in 2021. The annual percentage change (APC) in female first authorship took place in 2019 [APC for 2019-2021, 37.03, 95% confidence interval (CI): 18.0-59.1, P=0.003]. The proportion of first authors in TLCR increased from 25.9% in 2012 to 42.8% in 2021 and showed the greatest rise in female first authorship. There were significant discrepancies in the female first authorship across the journals and regions. Among the 3,612 corresponding authors whose sex were determined, 884 (24.5%) were female. There is no significant increasing trend in female corresponding authorship.
    Conclusions: The sex gap in the first authorship of lung cancer research articles has improved markedly in the recent years, however, sex imparities persist especially in corresponding authorship. There is an urgent need to proactively support and promote women in taking the leadership roles, thereby increasing their contributions to and influence on the development or advancement for future healthcare policies and practices.

    Insights into adeno-associated virus-based ocular gene therapy: A bibliometric and visual analysis.
    Xi Chen, Yang Yu, Huiling Nie, Xun Qin, Wen Bai, Junsong Ren, Jin Yao, Juxue Li, Qin Jiang.
       BACKGROUND: Adeno-associated virus (AAV) plays a vital role in ocular gene therapy and has been widely studied since 1996. This study summarizes and explores the publication outputs and future research trends of AAV-based ocular gene therapy.
    METHODS: Publications and data about AAV-based ocular gene therapy were downloaded from the Web of Science Core Collection or ClinicalTrials.gov database. The publications and data were analyzed by Microsoft Excel, CiteSpace, VOS viewer, and a free online platform (http://bibliometric.com).
    RESULTS: Totally 832 publications from the Web of Science Core Collection relevant to AAV-based ocular gene therapy were published from 1996 to 2022. These publications were contributed by research institutes from 42 countries or regions. The US contributed the most publications among these countries or regions, notably the University of Florida. Hauswirth WW was the most productive author. "Efficacy" and "safety" are the main focus areas for future research according to the references and keywords analysis. Eighty clinical trials examined AAV-based ocular gene therapy were registered on ClinicalTrials.Gov. Institutes from the US and European did the dominant number or the large proportion of the trials.
    CONCLUSIONS: The research focus of the AAV-based ocular gene therapy has transitioned from the study in biological theory to clinical trialing. The AAV-based gene therapy is not limited to inherited retinal diseases but various ocular diseases.

    Publication Trends in Research on Mental Health and Mental Illness in Orthopaedic Surgery: A Systematic Review.
    Jessica Schmerler, Lorenzo Solon, Andrew B Harris, Matthew J Best, Dawn LaPorte.
       BACKGROUND: Mental health conditions affect tens of millions of Americans. In recent years, particularly with the advent of the coronavirus disease 2019 pandemic, there has been a burst of interest in mental health and mental illness among orthopaedic surgical patients. The mental health of orthopaedic surgeons themselves has also come into focus, with high reported rates of burnout and depression. The aim of this article was to evaluate trends in publication on mental health and mental illness in orthopaedic surgery.
    METHODS: Web of Science and PubMed were queried to conduct a systematic review. Studies that discussed orthopaedic surgery and mental illnesses or mental health topics over 2001 to 2022 were included. Publications were analyzed by article-, author-, and topic-level characteristics.
    RESULTS: A total of 416 studies were analyzed after application of inclusion and exclusion criteria. Publication volume increased dramatically, demonstrating quadratic growth over 2001 to 2022 (p < 0.001). Eighty-eight percent of studies focused on patients and 10% on surgeons, with studies about patients more likely to focus on mental illness and those about surgeons more likely to focus on mental health (p < 0.001). Twenty percent of publications had a female senior author, and 5 authors collectively accounted for 10% of all publications. Eight journals published more than 10 publications, accounting for 35% of all publications. The most productive subspecialties were arthroplasty (135, 30%), general orthopaedics (87, 21%), and spine (69, 17%). Mental illnesses that were least represented included schizophrenia, bipolar disorder, eating disorders, attention-deficit/hyperactivity disorder, and personality disorders (1% or less of total publications each).
    CONCLUSION: This analysis showed a dramatically increasing trend in publications on mental health and mental illness in orthopaedic surgery. A high concentration of publications came from a subset of journals and senior authors, and women were overrepresented as senior authors relative to their representation in the field. The results of this analysis identified gaps in the literature, including underrepresented subspecialties, understudied mental illnesses, and study of orthopaedic surgeon mental health, and thus highlighted areas for future investigation.

    Identifying Latent Topics and Trends in Premature Infant-Related Nursing Studies Using a Latent Dirichlet Allocation Method.
    Myeong Seon Lee, Seonah Lee.
      This study aimed to identify topics and within-topic core keywords in premature infant-related nursing studies published in Korean and international academic journals using topic modeling and to compare and analyze the trends in Korean and international studies. Journal databases were searched to extract nursing studies involving premature infants from 1998 to 2020. Journal databases included MEDLINE, Web of Science, CINAHL, and EMBASE for international studies and DBpia, the National Digital Science Library, the Korea Citation Index, and the Research Information Sharing Service for Korean studies. Abstracts from the selected 182 Korean and 2502 international studies were analyzed using NetMiner4.4.3e. In results, four similar topics (Korean vs international) were "pain intervention" versus "pain management"; "breast feeding practice" versus "breast feeding"; "kangaroo mother care"; and "parental stress" versus "stress & depression." Two topics that appeared only in the international studies were "infection management" and "oral feeding & respiratory care." Overall, the international studies dealt with diverse topics directly associated with premature. Korean studies mainly dealt with topics related to mothers of premature infants, whereas studies related to premature infants were insufficient. Nursing research in Korea needs to be expanded to research topics addressing premature infants.

    Characteristics, treatment and research development of bertolotti's syndrome: a bibliometric analysis and systematic review.
    Wenhao Zhu, Xing Ding, Jiale Zheng, Fan Zeng, Fan Zhang, Xuequn Wu, Yijun Sun, Junming Ma, Mengchen Yin.
       PURPOSE: Bertolotti's syndrome is a prevalent congenital deformity. However, many physicians fail to include it in their differential diagnosis for low back pain (LBP), which results in missed diagnosis or misdiagnosis. There is still a lack of standardized treatment and management strategies for Bertolotti's syndrome. This study aimed to review the clinical characteristics and management of Bertolotti's syndrome and reports bibliometric insights in advancements in Bertolotti's syndrome research.
    METHODS: Studies published until September 30, 2022 were systematically reviewed according to the PRISMA guidelines. Three independent reviewers extracted the data and assessed the quality and risk of bias of the studies based on the methodological index of non-randomized studies (MINORS). SPSS, VOS viewer, and the Citespace software were used for the systematic review, visual analysis, data mining, mapping, and clustering of the retrieved articles, which presented clear and visual presentations of the structural patterns of published research in graphs.
    RESULT: A total of 118 articles, describing a total of 419 patients with Bertolotti's syndrome, were included. There was an upward trend with a steady increase in the number of publications. The world map distribution showed that most publications were predominantly from North America and Asia. The most cited articles were published in the following journals: Spine, The Journal of Bone and Joint Surgery, and Radiology. The mean age of the patients was 47.7 years, and 49.6% of them were male. A total of 159 (96.4%) patients had low back pain symptoms. The mean symptom duration was 41.4 months (74.8%), and most of the patients had Castellvi type II. Disc degeneration was the most reported comorbid spinal diseases. The mean MINORS score was 4.16±3.95 points (range, 1-21). A total of 265 (68.3%) patients underwent surgical treatments. Minimally invasive surgical techniques, prevalence, image classification, and disc degeneration were the current main research areas of Bertolotti's syndrome.
    CONCLUSIONS: The steady increase in the number of publications demonstrated the increased attention of researchers on this topic. Our results showed a significant prevalence of Bertolotti's syndrome in patients with LBP and a long symptom duration before the initiation of treatment. Surgical treatments were commonly used to treat patients with Bertolotti's syndrome after a non-effective conservative treatment. Minimally invasive surgical techniques, prevalence, image classification, and disc degeneration are the major research areas of Bertolotti's syndrome.

    Democratic governance and global science: A longitudinal analysis of the international research collaboration network.
    Travis A Whetsell.
      The democracy-science relationship has traditionally been examined through philosophical conjecture and country case studies. There remains limited global-scale empirical research on the topic. This study explores country-level factors related to the dynamics of the global research collaboration network, focusing on structural associations between democratic governance and the strength of international research collaboration ties. This study combines longitudinal data on 170 countries between 2008 and 2017 from the Varieties of Democracy Institute, World Bank Indicators, Scopus, and Web of Science bibliometric data. Methods include descriptive network analysis, temporal exponential random graph models (TERGM), and valued exponential random graph models (VERGM). The results suggest significant positive effects of democratic governance on the formation and strength of international research collaboration ties and homophily between countries with similar levels of democratic governance. The results also show the importance of exogenous factors, such as GDP, population size, and geographical distance, as well as endogenous network factors, including preferential attachment and transitivity.

    A scientometric and descriptive review on the debate about repressed memories and traumatic forgetting.
    Fabiana Battista, Ivan Mangiulli, Lawrence Patihis, Olivier Dodier, Antonietta Curci, Tiziana Lanciano, Henry Otgaar.
      Recent work suggests that the debate surrounding repressed memory and traumatic forgetting continues today. To further investigate this debate, we performed preregistered scientometric analyses on publications on the debate about repressed memory to provide information about its bibliometric evolution. Furthermore, we reviewed these publications to highlight the different positions taken by scholars on this debate. We reviewed 434 publications extracted from Scopus and Web of Science from 1969 to 2022. Our scientometric analyses permitted us to visualize the development of the publications on repressed memories and identify the terminology used to label this phenomenon. We identified three waves of publications (i.e., 1994-2000; 2003-2009; 2012-2021) showing that there is a recent peak of scholarly attention into this topic. 40% of scholars supported the phenomenon of repressed memory while 29% did not. Moreover, although in the last wave of publications, 35% of articles included critical arguments against the existence of repressed memory, a sizable number of publications (21%) supported ideas in favour of repressed memory. Finally, we observed that the term dissociative amnesia is another expression used to refer to the phenomenon. Our results provide additional evidence that the debate on repressed memories (and dissociative amnesia) is far from being over.

    Visual analysis of the prevention and control measures of COVID-19 in Chinese ports.
    Chunyan Huang, Yuanming Qiu, Yiliang Fang, Guangmin Chen, Xinying Xu, Jianfeng Xie, Zhijian Hu, Kuicheng Zheng, Fei He.
      In 2022, COVID-19 solutions in China have entered a normal stage, and the solutions imported from ports have been transformed from emergency prevention and control measures to investigative long-term prevention and control measures. Therefore, it is necessary to study solutions for COVID-19 at border ports. In this study, 170 research papers related to the prevention and control measures of COVID-19 at ports from 2020 to September 2022 were retrieved from Wanfang database, HowNet database, Wip database, and WoS core collection. Citespace 6.1.R2 software was used to research institutions visualize and analyze researchers and keywords to explore their research hotspots and trends. After analysis, the overall volume of documents issued in the past 3 years was stable. The major contributors are scientific research teams such as the Chinese Academy of Inspection and Quarantine Sciences (Han Hui et al.) and Beijing Customs (Sun Xiaodong et al.), with less cross-agency cooperation. The top five high-frequency keywords with cumulative frequency are as follows: COVID-19 (29 times), epidemic prevention and control (29 times), ports (28 times), health quarantine (16 times), and risk assessment (16 times). The research hotspots in the field of prevention and control measures for COVID-19 at ports are constantly changing with the progress of epidemic prevention and control. Cooperation between research institutions needs to be strengthened urgently. The research hotspots are the imported epidemic prevention and control, risk assessment, port health quarantine, and the normalized epidemic prevention and control mechanism, which is the trend of research and needs further exploration in the future.

    Hydrogel Applicability for the Industrial Effluent Treatment: A Systematic Review and Bibliometric Analysis.
    Luis Enrique Flores-Valenzuela, José Vulfrano González-Fernández, María Verónica Carranza-Oropeza.
      In recent decades, hydrogels, as adsorption materials, have received important attention due to their characteristics and properties, such as mechanical strength, biocompatibility, biodegradability, swellability, and stimuli sensitivity. In the actual framework of sustainable development, it has been imperative to develop practical studies of hydrogels in the treatment of actual industrial effluents. Accordingly, the current work has, as its objective, to make evident hydrogels' applicability in the treatment of actual industrial effluents. For this purpose, a bibliometric analysis and systematic review based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) method were conducted. The relevant articles were selected from the Scopus and Web of Science databases. Some important findings were that: (1) China is the leading country when it comes to hydrogel application in actual industrial effluents, (2) the motor studies are focalized on the treatment of wastewater by hydrogels, (3) the fixed-bed columns are suitable unit equipment for the treatment of industrial effluents of using hydrogels, and (4) the hydrogels show excellent adsorption capacities of ion and dye contaminants present in industrial effluents. In summary, since the implementation of sustainable development in 2015, the progress of practical hydrogel applications in the treatment of industrial effluent has been receiving more attention, and the selected studies demonstrate the implementation viability of these materials.

    Tawil Samah.
       Background: Health improvements are considered one of the most important fields of research. Since the coronavirus disease 2019 was declared a pandemic, it might have impacted clinical and public health research in various forms.
    Objectives: The goal of this study is to explore health research approaches in the era of coronavirus disease 2019.
    Methods: In this scoping review, we reviewed published medical full-text studies and identified potential areas of interest of health research in the era the coronavirus disease 2019 pandemic during the last 3 years within a higher educational setting. A bibliometric analysis was used to compare among published works.
    Results: Among the 93 studies that met the inclusion criteria, most focused on mental health (n = 23; 24.7%). Twenty-one publications targeted coronavirus disease 2019 and its consequences on general health. Other studies have described hemato-oncological, cardiovascular, respiratory, and endocrinological diseases. 42 studies were cross-sectional or cohort studies and most of them published in Q1 journals. Almost half of them belonged to the Faculty of Medicine (49.5%) followed by the School of Arts, Sciences, and Psychology (26.9%).
    Conclusions: Health research has been demonstrated to be important, at all times, especially during crises. Therefore, researchers need to invest more efforts into seeking new medical updates in various health-related fields, regardless of their correlation with coronavirus disease 2019.

    How Many Chemicals in Commerce Have Been Analyzed in Environmental Media? A 50 Year Bibliometric Analysis.
    Derek C G Muir, Gordon J Getzinger, Matt McBride, P Lee Ferguson.
      Over the past 50 years, there has been a tremendous expansion in the measurement of chemical contaminants in environmental media. But how many chemicals have actually been determined, and do they represent a significant fraction of substances in commerce or of chemicals of concern? To address these questions, we conducted a bibliometric survey to identify what individual chemicals have been determined in environmental media and their trends over the past 50 years. The CAplus database of CAS, a Division of the American Chemical Society, was searched for indexing roles "analytical study" and "pollutant" yielding a final list of 19,776 CAS Registry Numbers (CASRNs). That list was then used to link the CASRNs to biological studies, yielding a data set of 9.251 × 106 total counts of the CASRNs over a 55 year period. About 14,150 CASRNs were substances on various priority lists or their close analogs and transformation products. The top 100 most reported CASRNs accounted for 34% of the data set, confirming previous studies showing a significant bias toward repeated measurements of the same substances due to regulatory needs and the challenges of determining new, previously unmeasured, compounds. Substances listed in the industrial chemical inventories of Europe, China, and the United States accounted for only about 5% of measured substances. However, pharmaceuticals and current use pesticides were widely measured accounting for 50-60% of total CASRN counts for the period 2000-2015.

    NIH Funding Among Vascular Surgeons is Rare.
    Amin A Mirzaie, Michol A Cooper, M Libby Weaver, Christopher R Jacobs, Morgan L Cox, Scott A Berceli, Salvatore T Scali, Martin R Back, Thomas S Huber, Gilbert R Upchurch, Samir K Shah.
       INTRODUCTION: The National Institutes of Health (NIH) is an essential source of funding for vascular surgeons conducting research. NIH funding is frequently used to benchmark institutional and individual research productivity, help determine eligibility for academic promotion, and as a measure of scientific quality. We sought to appraise the current scope of NIH funding to vascular surgeons by appraising the characteristics of NIH funded investigators and projects. In addition, we also sought to determine whether funded grants addressed recent Society for Vascular Surgery (SVS) research priorities.
    METHODS: In April 2022, we queried the NIH Research Portfolio Online Reporting Tools Expenditures and Results (NIH RePORTER) database for active projects. We only included projects that had a vascular surgeon as a principal investigator (PI). Grant characteristics were extracted from the NIH RePORTER database. PI demographics and academic background information were identified by searching institution profiles.
    RESULTS: There were 55 active NIH awards given to 41 vascular surgeons Only 1% (41/4037) of all vascular surgeons in the United States receive NIH funding. Funded vascular surgeons are an average of 16.3 years out of training; 37% (n=15) are women. The majority of awards (58%, n=32) were R01 grants. Among the active NIH-funded projects, 75% (n=41) are basic/translational research projects, while 25% (n=14) are clinical/health services research projects. Abdominal aortic aneurysm (AAA) and peripheral arterial disease (PAD) are the most commonly funded disease areas and together accounted for 54% (n=30) of projects. Three SVS research priorities are not addressed by any of the current NIH-funded projects.
    CONCLUSIONS: NIH funding of vascular surgeons is rare and predominantly consists of basic/translational science projects focused on AAA and PAD research. Women are well-represented among funded vascular surgeons. While the majority of SVS research priorities receive NIH funding, three SVS research priorities are yet to be addressed by NIH funded projects. Future efforts should focus on increasing the number of vascular surgeons receiving NIH grants and ensuring all SVS research priorities receive NIH funding.

    Who takes care of intensive care? Changes over the last two decades.
    O Karcioglu, H N Karaaslan, A M Karcioglu.
       OBJECTIVE: Intensive care units are very important across various fields of medicine, and there are many high-quality journals that publish about intensive care. However, there is a lack of information regarding which disciplines publish the most in these journals. We aim to evaluate the intensive care literature.
    MATERIALS AND METHODS: We searched the papers published in the American Journal of Respiratory and Critical Care Medicine, Intensive Care Medicine, Critical Care Medicine and Critical Care to gain information regarding authors' specializations. We collected specialization data from PubMed, Google Scholar, and also from various journal websites. We examined the changes in the proportion of disciplines that are actively contributing to intensive care literature.
    RESULTS: Regardless of the year and the journal, intensivists were the most common writers (1,047/4,807, 21.8%) overall. This was followed by pulmonology (843, 17.5%), anesthesia (827, 17.2%), others (602, 12.5%), and pediatrics (374, 7.8%). The United States of America (1,470/30.8%), France (573/11.2%), and Germany (332/6.9%) were at the top of the list in terms of productivity.
    CONCLUSIONS: With the increase in the number of intensive care units and the development of an understanding of intensive care, we observed that intensivists are publishing more in intensive care literature.

    Representation of women in musculoskeletal radiology conferences in Europe and North and South Americas: an estimation and comparative analysis.
    Tatiane Cantarelli Rodrigues, Erika Antunes, Pedro Dias, Aline Serfaty.
       OBJECTIVE: To assess gender distribution and disparities in the musculoskeletal field at radiology conferences and to identify factors associated with the imbalance of women speakers.
    MATERIALS AND METHODS: This cross-sectional study evaluated publicly available data online from musculoskeletal radiology conference programs from radiological societies across Europe, North America (NA), and South America (SA) from 2016 to 2020. The gender of invited speakers, moderators, and planning committee members and the occurrence of single-gender panels for musculoskeletal and plenary sessions were assessed.
    RESULTS: A total of 531 sessions, 2580 speakers, 603 moderators, and 231 planning committee members were assessed. Women accounted for 26.6% of total speakers (p<0.001), 33.3% of moderators (p<0.001), and 31.2% of planning committee members (p=0.381). All-male panels were 26.7%, with 21.1% of women moderating these panels (p<0.001). The proportion of women speakers in musculoskeletal and plenary sessions was 29.7% and 34.6% in NA (p=0.035, p=0.052), 26.6% and 25.0% in Europe (p<0.001, p=0.199), and 12.9% and 13.6% in SA (p<0.001). The proportion of women moderators was 35.0% in NA (p=0.002), 37.1% in Europe (p=0.914), and 13.8% in SA (p<0.001). A linear relationship was observed in the proportion of women speakers, moderators, and members of the planning committee (p<0.05).
    CONCLUSION: We evaluated the participation of women speakers in musculoskeletal radiology conference programs, with significant differences in Europe and South America in all years evaluated, and the participation of women moderators with significant differences in South America and in all-male panels in all regions. Acknowledging gender biases and increasing the number of women on planning committees may help address gender imbalance and promote gender equity.

    New Challenges in Scientific Publications: Referencing, Artificial Intelligence and ChatGPT.
    Igor Švab, Zalika Klemenc-Ketiš, Saša Zupanič.
      The COVID-19 pandemic has led to a surge in scientific publications, some of which have bypassed the usual peer-review processes, leading to an increase in unsupported claims being referenced. Therefore, the need for references in scientific articles is increasingly being questioned. The practice of relying solely on quantitative measures, such as impact factor, is also considered inadequate by many experts. This can lead to researchers choosing research ideas that are likely to generate favourable metrics instead of interesting and important topics. Evaluating the quality and scientific value of articles requires a rethinking of current approaches, with a move away from purely quantitative methods. Artificial intelligence (AI)-based tools are making scientific writing easier and less time-consuming, which is likely to further increase the number of scientific publications, potentially leading to higher quality articles. AI tools for searching, analysing, synthesizing, evaluating and writing scientific literature are increasingly being developed. These tools deeply analyse the content of articles, consider their scientific impact, and prioritize the retrieved literature based on this information, presenting it in simple visual graphs. They also help authors to quickly and easily analyse and synthesize knowledge from the literature, prepare summaries of key information, aid in organizing references, and improve manuscript language. The language model ChatGPT has already greatly changed the way people communicate with computers, bringing it closer to human communication. However, while AI tools are helpful, they must be used carefully and ethically. In summary, AI has already changed the way we write articles, and its use in scientific publishing will continue to enhance and streamline the process.

    Analysis of peer reviewers' response to invitations by gender and geographical region: cohort study of manuscripts reviewed at 21 biomedical journals before and during covid-19 pandemic.
    Khaoula Ben Messaoud, Sara Schroter, Mark Richards, Angèle Gayet-Ageron.
       OBJECTIVES: To describe gender and geographical inequalities in invitations to review and the response to these invitations and to assess whether inequalities increased during the covid-19 pandemic.
    DESIGN: Retrospective cohort study.
    SETTING: 19 specialist medical journals and two large general medical journals from BMJ Publishing Group.
    POPULATION: Reviewers invited to review manuscripts submitted between 1 January 2018 and 31 May 2021. The cohort was followed up to 28 February 2022.
    MAIN OUTCOME MEASURES: Reviewer's agreement to review.
    RESULTS: A total of 257 025 reviewers were invited (38.6% (88 454/228 869) women), and 90 467 (35.2%) agreed to review. Invited reviewers were mainly (217 682; 84.7%) affiliated with high income countries: Europe (122 414; 47.6%), North America (66 931; 26.0%), Africa (25 735; 10.0%), Asia (22 693; 8.8%), Oceania (16 175; 6.3%), and South America (3076; 1.2%). Independent factors associated with agreement to review were gender (odds ratio 0.89, 95% confidence interval 0.87 to 0.92, for women compared with men), geographical affiliation (2.89, 2.73 to 3.06, for Asia; 3.32, 2.94 to 3.75 for South America; 1.35, 1.27 to 1.43, for Oceania; and 0.35, 0.33 to 0.37, for Africa compared with Europe), and country income (0.47, 0.45 to 0.49, for upper middle income; 5.12, 4.67 to 5.61, for lower middle income; and 4.66, 3.79 to 5.73, for low income compared with high income country). Agreement was also independently associated with editor's gender (0.96, 0.93 to 0.99, for women compared with men), last author's geographical affiliation (0.80, 0.78 to 0.83, for Asia; 0.89, 0.85 to 0.94, for Oceania compared with Europe), impact factor (1.78, 1.27 to 2.50, for >10 compared with <5), and type of peer review process (0.52, 0.35 to 0.77, for open compared with anonymised). During the first and second phases of the pandemic, agreement was lower than in the pre-pandemic period (P<0.001). The interaction between time periods and covid-19 related topic and reviewer's gender was non-significant. However, significant interaction was found between time periods and covid-19 related topic and reviewer's geographical affiliation.
    CONCLUSIONS: To reduce bias and improve diversity, editors need to identify and implement effective strategies and continually evaluate progress against these to ensure that more women and researchers from upper middle income and low income countries are involved in review.

    (How) Do We Theorize?: A Focused Mapping Review and Synthesis of Theoretical Nursing Research in the German-Speaking Area.
    Jasmin Eppel-Meichlinger, Ana Cartaxo, Theresa Clement, Julian Hirt, Martin Wallner, Hanna Mayer.
      There are increasing discussions on theory dynamics in nursing research. We aimed at mapping the theoretical publication output by nursing researchers from the European German-speaking area. We conducted a focused mapping review and synthesis, focusing on nursing journals articles with a theory-related aim. We identified 32 eligible publications, reflecting 2% of the nursing journal articles affiliated with researchers from our target region. Twenty-one articles involved an inductive approach. Eleven articles intended to test or revise a theory. The theoretical publication output with a theory-related aim was low. Theory-building efforts were fragmented and mostly without reference to a meta-theoretical level.

    Use of Publicly Obtained Data in Sports Medicine Research: A Systematic Review and Bibliometric Analysis.
    Paul M Inclan, Andrew W Kuhn, Stockton C Troyer, Gary S Solomon, Matthew J Matava.
       BACKGROUND: Publicly obtained data (POD) have recently been utilized frequently by sports medicine researchers to describe injury patterns, risk factors, and outcomes in elite athletes. The relative ease of this type of research that is based solely on internet and media sources has resulted in a near exponential increase in the number of these POD studies.
    PURPOSE: To systematically review the sports medicine literature for studies based solely on POD.
    STUDY DESIGN: Systematic review and bibliometric analysis; Level of evidence, 4.
    METHODS: A systematic review of POD studies published since 2000 was conducted in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Studies of interest were those relying on publicly available injury reports or online media for data acquisition in collegiate, semiprofessional, and professional athletes.
    RESULTS: There were 209 POD studies published between 2000 and 2022, with 173 (82.8%) of these studies published after 2016. Studies were published most frequently on athletes participating in North American professional leagues: National Football League (n = 69 [28.4%]), Major League Baseball (n = 56 [23.0%]), National Basketball Association (n = 37 [15.2%]), and National Hockey League (n = 33 [13.6%]). The most common injuries assessed were head injuries/concussions (n = 43 [21.1%]), anterior cruciate ligament injuries (n = 33 [16.2%]), and ulnar collateral ligament injuries (n = 23 [11.3%]). One-quarter of the studies (n = 53 [25.4%]) reported only 1 POD source, and 1 study (0.5%) reported no source. Additionally, 65 studies (31.1%) listed nonspecific POD resources or solely cited previous literature to describe the POD search methodology and data acquisition.
    CONCLUSION: POD studies are exponentially increasing in number, particularly across major North American professional sports leagues, with significant variability in the injury of interest, search methodology, and number of data sources. The accuracy of the conclusions reached based on the POD methodology appears highly variable. Given the potential impact of these publications as both contributors to current knowledge and drivers of future research, the sports medicine community should be aware of the inherent biases and limitations of POD injury studies.

    Assessment of spin in the abstracts of randomized controlled trials in dental caries with statistically nonsignificant results for primary outcomes: A methodological study.
    Naichuan Su, Michiel W van der Linden, Clovis M Faggion, Geert J M G van der Heijden.
      The study aimed to assess the prevalence of spin in the titles and abstracts of RCTs in dental caries with statistically nonsignificant primary outcomes and to assess the risk indicators which may be associated with spin. Any original publication reporting a two-arm RCT in dental caries with clearly identified statistically nonsignificant primary outcomes published from January 1, 2015 until October 28, 2022 were included. PubMed was searched electronically to identify the eligible publications. The prevalence of spin in titles and abstracts were assessed and categorized into spin patterns based on a pre-determined classification scheme. The association between spin and the potential risk indicators at study, author, journal, institutional, and national level was assessed. A total of 234 eligible RCT publications were included. The prevalence of spin in the titles and abstracts was 3% (95%CI: 2% to 6%) and 79% (95%CI: 74% to 84%), respectively. The most common spin patterns in the results and conclusion sections, respectively, were results focusing on statistically significant within-group comparisons (23%), and conclusions focusing only on statistically significant results without acknowledgment of statistically nonsignificant results for the primary outcomes (26%). The spin was significantly associated with number of study centers (single-center vs. multicenter) (OR=2.131; 95%CI: 1.092 to 4.158; P=0.03), trial designs (non-parallel designs vs. parallel designs) (OR=0.395; 95%CI: 0.193 to 0.810; P=0.01), and overall H index of institutions for last authors (OR=0.998; 95%CI: 0.996 to 0.999; P<0.01), while it was not significantly associated with the other indicators. In the RCT publications with statistically nonsignificant results for primary outcomes in dental caries, the prevalence of spin may be low in the titles but high in the abstracts. Single-center studies with parallel designs and a lower overall H index of institutions for last authors may be more likely to have spin in the abstracts.
