    The 100 most-cited articles published in the Veterinary Ophthalmology journal between 1998 and 2022: A bibliometric study.
    Dikla Arad, Oren Pe'er, Ron Ofri.
       PURPOSE: The aim of this study was to bibliometrically analyze the 100 most-cited articles published in the Veterinary Ophthalmology (VO) journal.
    METHODS: Web of Science was searched for citations of VO articles published in 1998-2022. Tissue and species studied, and first and last author domicile and affiliation were recorded for the 100 most-cited articles and descriptively analyzed.
    RESULTS: Altogether, the 100 most-cited VO articles have cited a total of 5483 times. Most commonly, these were devoted to the cornea (23%), multiple tissues (19%), and glaucoma (16%). Studies on dogs (36%), horses (17%), and multiple species (15%) were most often cited. Most first/last authors were from the USA (n = 113), Brazil (n = 13), and France and Germany (n = 7 each), and most frequently affiliated with the University of Florida (n = 36), University of Wisconsin-Madison (n = 15), and Animal Health Trust, North Carolina State University, and Ohio State University (n = 6 each). KN Gelatt (n = 9), DE Brooks (n = 6), and FJ Ollivier and EO MacKay (n = 5 each) were the most frequent first or last authors. The greatest number of citations was for articles with KN Gelatt (n = 555), FJ Ollivier (n = 411), and DE Brooks (n = 372) as first or last authors. "The comparative morphology of the tapetum lucidum" by FJ Ollivier et al. (2002) is the most frequently cited article in VO history (n = 178).
    CONCLUSIONS: This study provides insight into the impact of publishing in VO and a more comprehensive understanding of trends and the most influential contributions to VO.

    Assessing the impact of publications: A bibliometric analysis of the top-cited articles from The Journal of Thoracic and Cardiovascular Surgery.
    Alejandra Castro-Varela, Hartzell V Schaff.
       OBJECTIVE: After 90 years, The Journal of Thoracic and Cardiovascular Surgery (JTCVS) remains one of the most influential and widely read journals in our specialty. This study analyzes the characteristics of its top-cited articles over the past 6 decades.
    METHODS: Using Elsevier's Scopus database, we identified all papers published in JTCVS since 1959. After exclusion of expert consensus guidelines, articles were grouped by decade and ranked by the total number of citations. We included the field-weighted citation impact (FWCI) when available. We analyzed the characteristics of the 10 most cited documents overall and per decade.
    RESULTS: The Journal published a total of 32,335 papers, of which 14,052 were published between 2010 and 2021. The order of the top-cited articles differs when ranked by citations versus FWCI. During the last 6 decades, the 10 most cited articles per decade have a mean number of 604 citations (range, 240-1670) and a mean FWCI of 13.1 (range, 4.3-24.7). There is no overlap in positions when articles are ranked by citations versus FWCI. The majority of the 60 top 10 cited articles over the past 6 decades were presented at a major meeting (n = 38, 63%), most commonly the Annual Meeting of the American Association for Thoracic Surgery. Topics in adult cardiac surgery and general thoracic surgery predominated among the most-cited papers, which originated most often from the United States followed by Japan, Canada, France, England, and Germany.
    CONCLUSIONS: JTCVS continues to provide a global platform to share impactful knowledge related to surgery for thoracic diseases. The use of citations to determine an article's impact has limitations and nontraditional metrics may prove to be an excellent complementary tool for more equitable evaluations.

    Yuanqing Gou, Yongxin Fu, Yadong Li, Chuan Liu.
       Background: This review aimed to analyze the research progress and development trends in targeted therapy (TT) for renal cancer (RC) from 2006 to 2022.
    Methods: The Web of Science Core Collection database was searched using the search terms "renal cancer", "kidney neoplasms", "kidney cancer", and "targeted therapy", and all publications were extracted. VOSviewer version 1.6.18 was used to complete the visual analysis based on the information of publications, including author, journal, subject, year, and institution.
    Results: A total of 1,136 studies related to TT for RC were found. The top journals in this field were the Journal of Clinical Oncology, Annals of Oncology, and European Urology. Among them, the Journal of Clinical Oncology had the highest number of publications (n=35). In terms of country, the United States had the highest number of publications (n=366). The main document type was article, which accounted for 64.26% of the total publications.
    Conclusions: To the best of our knowledge, this is the first bibliometric analysis related to TT for RC. The annual number of publications has exhibited a steady growth trend, with the United States having the greatest contribution in this field. Through an analysis of a keyword time density map, we identified that hypoxia-inducing factor-1, drug resistance and therapeutic targets are the research hotspots and trends in this field.

    Marco Tullio Becheleni, Marina Rocha Fonseca Souza, Endi Lanza Galvão, Essam Ahmed Al-Moraissi, Saulo Gabriel Moreira Falci.
       PURPOSE: This study aimed to compile a list of the 100 most cited articles on mandibular fractures and to glean key insights from these articles via a bibliometric analysis.
    METHODS: This bibliometric analysis was performed using the Web of Science Core Collection database. The search was performed through January 2022. The bibliometric parameters extracted included title, number of citations, citation density (number of citations per year), first author's country, year of publication, study design, and subject. The software program VOSviewer was used to create graphical bibliometric maps.
    RESULTS: The articles were ranked by the total number of citations, which ranged from 64 to 374, with 32 articles being cited more than 100 times. The included articles were published from 1952 to 2015, mainly in maxillofacial surgery journals. The most frequent of these were the Journal of Oral and Maxillofacial Surgery (54%) and the International Journal of Oral and Maxillofacial Surgery (14%). The studies were from 29 different countries, with the United States of America (42%) contributing substantially more than others, with the next ranked nation being Germany (9%). The most frequently used keywords were osteosynthesis (25), open reduction (18), and fixation (16).
    CONCLUSIONS: The country that contributed most to mandibular fracture research was the United States of America. This conclusion was based on the number of published articles by nation of origin and the origin of the Journal of Oral and Maxillofacial Surgery, in which the majority were published. Osteosynthesis was the most cited field of research among the articles in the sample set.

    Bibliometric Analysis of 6 Major European Neurosurgical Publications from 2011-2020 (part 3): a Comparative Metrics Review.
    Kanwaljeet Garg, Bipin Chaurasia, Andrew J Gienapp, Bruno Splavski, Kenan I Arnautovic.
       Background: We previously conducted bibliometric analysis of 6 North American neurosurgical journals.
    Objective: To perform a bibliometric analysis of 6 European neurosurgical journals to build on our previous studies.
    Methods: We searched Web of Science for articles published in Acta Neurochirurgica, British Journal of Neurosurgery, Child's Nervous System, Journal of Neurological Surgery Part A: Central European Neurosurgery, Journal of Neurosurgical Sciences, and Neurosurgical Review between 2011 and 2020. We analyzed bibliometric parameters related to total annual document distribution, author metrics, journal metrics, country and continental distribution, institution, keywords, and journal impact.
    Results: European countries provided the greatest contributions. Acta Neurochirurgica followed by Child's Nervous System published the greatest number of articles and had the highest h-index and number of citations. From 2018 to 2020, total documents increased 79.6%, original articles increased 86.5%, review articles increased 103.6%, citations increased 79.6%, number of publishing authors increased 72.1%, number of authors in multi-author documents increased 72.4%, and author's keywords and keywords plus increased 72.4% and 27.0%, respectively. The collaboration index decreased 5.3% from 4.49 to 4.25. Annual published documents and citations were lower for European journals versus North American journals.
    Conclusion: Several parameters of the European journals increased by 2020. One interesting finding is that growth for the 6 journals dramatically increased in the 2 years prior to the COVID-19 pandemic. While neurosurgeon free time during lockdowns may account for much of the increase in 2020, the trend began before this. Our analysis did not identify a cause for the pre-COVID increases.

    Research trends of omics in ulcerative colitis: A bibliometric analysis.
    He Zhang, Yuanyuan Ni, Hangyu Ji, Hongliang Liu, Shaoneng Liu.
       Background: Omics has emerged as a promising biological science to shed light on the etiology, pathogenesis, and treatment of ulcerative colitis (UC). At present, although research on the omics of UC has drawn global attention, there is still a lack of bibliometric analysis in this field. This study aimed to access the trends and hotspots of omics in UC research.
    Method: Publications related to omics in UC from 1 January 2000 to 15 October 2022 were retrieved from the Web of Science Core Collection database. VOSviewer, CiteSpace, and the online bibliometric analysis platform "Bibliometrix" were adopted to extract and visualize information.
    Results: A total of 385 publications were finally included and the annual number of publications fluctuated. The trend in publications increased rapidly after 2019. The United States showed its dominant position in several publications, total citations, and international collaborations. The top five research organizations for publications on the research of omics in UC were Harvard Medical School, the Icahn School of Medicine at Mount Sinai, Karolinska Institutet, the Brigham and Women's Hospital, and the Massachusetts General Hospital. Ashwin Ananthakrishnan from the Massachusetts General Hospital was the most productive author, and Séverine Vermeire from the Catholic University of Leuven was co-cited most often. Inflammatory bowel disease was the most popular and co-cited journal in this field. The reference with citation bursts and trend topics showed that "ulcerative colitis," "inflammatory bowel disease," "microbiome," "transcriptomics," "genomics," "metabolomics," "proteomics," "dysbiosis," "biomarkers," "loci," and "therapy" are currently research hotspots.
    Conclusion: Our study presents several important insights into the research trends and developments in the field of omics in UC, which will provide key information for further research.

    Global trends in research of achilles tendon injury/rupture: A bibliometric analysis, 2000-2021.
    Chenguang Wang, Zhaohui Jiang, Ran Pang, Huafeng Zhang, Hui Li, Zhijun Li.
       Background: The Achilles tendon is the strongest and most susceptible tendon in humans. Achilles tendon injuries and ruptures have gradually attracted research attention. However, a bibliometric analysis of global research in this field is lacking. This study involved a bibliometric analysis of the developmental trends and research hotspots in Achilles tendon injuries/ruptures from 2000 to 2021.
    Methods: Articles published between 2001 and 2021 were retrieved from an extended database of the Science Citation Index using Web of Science. VOSviewer and CiteSpace were used to analyze the relationships between publications, countries, institutions, journals, authors, references, and keywords.
    Results: This study included 3,505 studies of 73 countries, 3,274 institutions, and 12,298 authors and explored the cooperation between them and the relationships between citations. Over the past 22 years, the number of publications has significantly increased. Foot Ankle International has published the most papers on Achilles tendon injuries/ruptures, and British Journal of Sports Medicine is the most famous journal. Re-rupture, exosomes, acute Achilles tendon rupture, and tendon adhesions gradually become the research focus over the past few years.
    Conclusion: Achilles tendon injury and rupture are important research topics. A vast number of newly published papers on this topic have demonstrated that clinicians and researchers are interested in their study. Over time, these recent studies will be widely cited; therefore, this bibliometric analysis should be constantly updated.

    Research Hotspots and Trends on Acupuncture for Anti-Inflammation: A Bibliometric Analysis from 2011 to 2021.
    Bing Chen, Di Liu, Tao Li, Lijiang Zheng, Ling Lan, Niu Yang, Yinlan Huang.
       Purpose: We here explored the research status, research hotspots, and development trend of acupuncture against inflammation from both quantitative and qualitative aspects through bibliometrics.
    Methods: We used CiteSpace and VOSviewer to analyze the literature about acupuncture against inflammation from 2011 to 2021 in the Web of Science Core Collection database by using a visual knowledge map.
    Results: In total, 1479 articles were included, and the number of articles published each year exhibited an upward trend. The largest number of articles were published in China (661), followed by the United States (287) and South Korea (164). The most productive institution is Beijing University of Chinese Medicine (72), while the most influential institution is the Capital Medical University (0.28). Evidence-based Complementary and Alternative Medicine (131) is the journal that published most articles on the topic. Lin Yiwen is the most prolific author, and Borovikova L is the most influential co-cited author. The keywords that have burst in the last 2 years are inflammation and activation. The keywords with the highest frequency of use are electroacupuncture (EA), inflammation, and expression.
    Conclusion: The number of publications on acupuncture for anti-inflammation research is rapidly increasing. China is a productive country, but the influence of centrality is poor. Research institutions are concentrated in universities, and the whole collaborative network needs to be strengthened. The anti-inflammatory mechanism of acupuncture is the main focus of research in this field. Regulation of immune cell balance by acupuncture may be a hot topic in mechanism research. At present, immune cells, vagus nerve, signal pathway, inflammatory corpuscles, cytokines and neurotransmitters are popular research topics. In the future, the basic research of acupuncture for anti-inflammation transformed into clinical practice may be a trend. EA and bee venom acupuncture may be promising research directions for acupuncture treatment for inflammatory diseases.

    Nianzhe Sun, Lixin Ke, Liming Qing, Zheming Cao, Gaojie Luo, Yilei Lu, Panfeng Wu, Fang Yu, Xiaoyang Pang, Juyu Tang.
       OBJECTIVE: Vascularized composite allografts (VCAs) refer to the transplantation of multiple types of tissues during plastic and reconstructive surgery. Several publications have emerged in the field of VCA. However, there are no bibliometric studies on this topic. The aim was to multidimensionally analyze the knowledge base and hotspots in this subject.
    METHODS: We retrieved all publications related to VCA from the Web of Science Core Collection (WoSCC), published from 2002 to 2021. Next, scientometric analysis of different items was performed using various bibliometrics software to explore knowledge base, research hotspots, and advancement trends in this field.
    RESULTS: We included a total of 3,190 English articles from 2002 to 2021. The number of publications increased steadily annually. The United States produced the highest number of publications, followed by China. Most publications were from Harvard University, followed by Johns Hopkins University. The most authoritative academic journal was Plastic and Reconstructive Surgery. Transplantation occupied the first rank of co-cited journal list. Maria Z Siemionow may have the highest influence in the VCA field with the highest number of citations (n = 88) and co-cited references (n = 1252). Clinical studies on different allografts, immunosuppression, and tissue engineering were both the knowledge base and recent topics in VCA research.
    CONCLUSIONS: The first bibliometric study comprehensively summarized the trends and development of VCA research with steady growth over the past two decades. Currently, the most active topics are the clinical application of multiple allografts, immunosuppression strategies/therapies, and translation of tissue engineering to clinical practice.

    Jae Keun Park, Ji Woong Hwang.
       BACKGROUND: Malignant change from low-grade dysplasia to high-grade dysplasia and invasive carcinoma following an adenoma-carcinoma sequence is becoming more common in intraductal papillary mucinous neoplasm (IPMN) of the pancreas. The aim of this study is to analyze their main characteristics and recent research trends in IPMNs and consequently create better understandings of the current situation and trends.
    METHODS: A comprehensive search was performed in The Science Citation Index Expanded of the Web of Science. All articles between 1990 and 2021 were searched. VOS viewer (Leiden University, Leiden, Netherlands) was used for a qualitative and quantitative analysis of keywords, constituting maps based on co-occurrence matrix.
    RESULTS: A total of 1658 eligible articles were screened among the 3950 identified articles for this subject. Finally, 879 articles were included in this study. Many articles on IPMN have been published in Japan and South Korea. Tanaka published the highest number of articles (n = 26, citations = 11,143). The Pancreas published the highest number of articles. (n = 100, citations = 2533). These articles were grouped into 4 clusters including basic research, disease overview, management/prognosis and malignant IPMN by using bibliometric keywords network analysis. Overlay visualization demonstrates, a trend of the studies has been changed from basic research or disease to management or prognosis.
    CONCLUSIONS: In this study, we found and highlight the most cited and influential articles related to IPMN. Plus, this study analyzed global research trends in IPMN over the past 30 years and provides insight into the features and research hotspots of the articles in IPMN research.

    A leading author of meta-analysis does not have a dominant contribution to research based on the CJAL score: Bibliometric analysis.
    Julie Chi Chow, Sam Yu-Chieh Ho, Tsair-Wei Chien, Willy Chou.
       BACKGROUND: There have been nearly 200 thousand meta-analysis articles indexed by web of science (WoS) since 2013. To date, a bibliometric analysis of leading authors of meta-analyses that contribute to the field has not been conducted. Analyzing trend patterns in article citations and comparing individual research achievements (IRAs) are required following the extraction of meta-analysis articles. Using trend analysis, this study aims to verify the hypotheses that; The leading author has a dominant research achievement and; Recent articles that deserve worth reading can be identified.
    METHODS: In the WoS collection, we identified the top 20 authors with the most articles related to meta-analysis. Using coword analysis, 2882 articles were collected to cluster author collaborations and identify the top 3 authors with the highest weighted centrality degrees. Based on the CJAL (category, journal raking by impact factor, authorship, and L-index on article citation) score and absolute advantage coefficient (AAC), we compared the IRAs and identified the author who dominated the field significantly beyond the next 2 authors. In WoS collection, coword analysis was used to highlight the characteristics of research domains for the top authors contributing to meta-analyses. The selection of articles that deserve reading is based on a temporal heatmap.
    RESULTS: The top 2 authors were Young-Ho Lee (South Korea), Patompong Ungprasert (U.S.), and Brendon Stubbs (US) with CJAL scores of 240.71, 230.99, and 240.71, respectively. Based on the weak dominance coefficient (AAC = 0.49 < 0.50), it is evident that the leading meta-analysis author does not possess a significant dominant position over the next 2 leading authors in IRAs. Coword analysis was used to illustrate the characteristics of the 3 authors research domains. The 3 articles worth reading were selected based on a trend analysis of the last 4 years using the temporal heatmap.
    CONCLUSION: A coword analysis of meta-analysis studies identified 3 leading authors. There was no evidence that 1 author possessed a dominant position due to the lower AAC (=0.49 < 0.50) for the leading author. As we have demonstrated in this study, the CJAL score and the AAC can be applied to many bibliographical studies in the future.

    Zhiqun Liu, Fangping Yin, Nan Ruan, Dawei Zhang.
      Textile waste water contains dyes and chemicals that produce harmful vapors and exhaust gases, which is hazardous to the environment and public health. Therefore, it must be carefully treated before discharged. To understand the research evolution in the research area of textile waste water treatment, based on bibliometrics, an in-depth analysis of the publications and hotspots in this area was presented in this paper. For the analysis, totally 6774 papers related to the research area that are published between the year 1964 and 2023 were collected from the Web of Science Core Collection. Using CiteSpace and VOSviewer as bibliometric analysis tools, the collaboration of countries, regions, and organizations was investigated. Besides, an analysis for citation and co-citation of journals, authors, references, and co-occurrence of keywords was performed. The evolution of research hotspots in the three major research directions related to degradation, oxidation, and adsorption is also analyzed in this paper. The analysis results show that researches related to oxidation and adsorption are active in recent years, while nanocomposite adsorbents and graphene oxide are the current research hotspots.

    Zahi Abdul Sater, Theresa Farhat, Mohamed N Elsayed, Yara Youssef, Marium Husain, Malak Kaddoura, Lubna Jaber, Deborah Mukherji, Ali Taher.
       Background: Cancer represents a disproportionate burden in LMICs, especially conflict-affected countries in the MENA region. Research output on cancer fails to match the growing burden in the region. This bibliometric study aims to examine the status and trends of cancer research in fragile and conflict-affected settings in the MENA region from 2000 to 2021, while also incorporating economic and demographic indicators as additional factors of analysis.
    Methods: The Web of Science databases were searched for publications related to cancer research in Iraq, Lebanon, Libya, Palestine, Syria, and Yemen from January 1, 2000, to December 31, 2021. The retrieved publications were screened based on preset eligibility criteria and the final list was analyzed using the Bibliometrix Package in R to generate the annual scientific production and citations, journals, institutions, authors, collaborations, keywords, and title co-occurrence. Each country's annual scientific production was analyzed against its annual GDP per capita.
    Results: A total of 4,280 documents met the inclusion criteria in this research. The annual number of publications revealed a significant increase over the past 20 years. These publications were mostly published in international journals that had impact factors rated in the 3rd or 4th quartiles. The overall contribution of researchers from Fragile and Conflict-Affected Settings (FCS) to cancer research was 6.5% of the MENA cancer research productivity, despite comprising around 23% of the total MENA region's population. Lebanon had the highest publication productivity at the country level, followed by Iraq and Syria. GDP per capita was not significantly correlated with cancer research across the countries under investigation. At the institutional level, the American University of Beirut was the most prolific institution and had the highest number of collaborations and the widest range of cooperative partners. Most first authors were male researchers. There is an interest in cancer expression, prevalence, diagnosis, and management in terms of commonly researched topics.
    Conclusion: This study underscores the need for a concerted effort to improve cancer research outcomes in FCS, which can be achieved through targeted research, increased investment in research infrastructure and capacity-building initiatives, and greater regional and global collaboration.

    Rui Zhang, Xiaoqin Deng, Quan Liu, Xintian Zhang, Xinxin Bai, Shaohuang Weng, Min Chen.
      The phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) signaling pathway has gradually become a new target for the treatment of osteoarthritis (OA). Numerous studies of PI3K/Akt signaling in OA have been published in the past few years. By analyzing these research characteristics and qualities, we aimed to reveal the current research focus and emerging trends in PI3K/Akt signaling in OA. We searched the Web of Science database for relevant articles concerning the PI3K/Akt signaling pathway in OA published from inception to October 31, 2022. The following data were extracted: author name, article title, keywords, topic, publication country/region, institution, publication journal, journal impact factor, number of times cited, and H-index. VOSviewer and Excel 2019 were used to conduct the bibliometric study and visualize the analysis. A total of 374 publications were included in this study. In all selected articles, "orthopedics" was the dominant topic (252 of 374, 67.38%). The most productive year was 2021. Frontiers in Pharmacology published the most articles. The People's Republic of China has published the most articles worldwide. The top 5 keywords were "OA," "expression," "apoptosis," "chondrocytes," and "inflammation." The keywords "autophagy," "mitochondrial dysfunction," "inflammatory response," "cartilage degeneration," and "network pharmacology" have increased in recent years. Our study showed a growing trend in published articles related to the PI3K/Akt signaling pathway in OA. Inflammatory response, cartilage degeneration, and apoptosis remain central topics in the field. Research on autophagy, mitochondrial dysfunction, and network pharmacology is on the rise, and the focus on PI3K/Akt will continue to increase.

    Current global research on mandibular defect: A bibliometric analysis from 2001 to 2021.
    Yongdi Li, Duchenhui Li, Zhenglong Tang, Dongxiang Wang, Zhishan Yang, Yiheng Liu.
      Background: Mandibular defects can result from congenital deformities, trauma, tumor resection, and osteomyelitis. The shape was irregular because the lower jaw was radians. This involves teeth and jaw functions; therefore, the difficulty of bone repair is greater than that in other body parts. Several standard treatments are available, but they result in various problems, such as difficulties in skin flap transplantation and possible zone dysfunction, artificial material boneless combining ability, and a long treatment period. This study aimed to introduce the present status of research on mandibular defects to analyze the current introduction and predict future research trends through a bibliometric study. Methods: From 2001 to 2021, publications on mandibular defects were collected for bibliometric visualization using VOSviewer, CiteSpace, and Scimago Graphica software based on the Web of Science Core Collection. Results: This study analyzed 4,377 articles, including 1,080 published in the United States, 563 in China, and 359 in Germany, with an increase in the number of articles published over the past 20 years. Wikesjoe and Ulf Mai E had the most publications (p = 36) and citations (citations = 1,553). Shanghai Jiaotong University published the highest number of papers among the research institutions (p = 88). The most productive journal was Journal of Oral and Maxillofacial Surgery, and the cited literature was primarily classified as dentistry, dermatology, and surgery. Cluster Analysis of Co-occurrence Keywords revealed that highest number of core words were mandibular defects, mandibular reconstruction, and bone regeneration. The highest cited words were head and neck cancer, accuracy, and osteogenic differentiation. High-frequency terms of Cluster Analysis of References were osteosynthesis plate, tissue engineering, and rapid distraction rate. Conclusion: Over the past 20 years, the number of studies on mandibular defects has gradually increased. New surgical procedures are increasingly being used in clinical practice. Current frontier topics mainly focus on areas such as computer-aided design, 3D printing of osteotomy and reconstruction guide plates, virtual surgical planning, and bone tissue engineering.

    A bibliometric and visualized study on global trends of breast augmentation complications, 2011-2021.
    Hongyi Zhang, Lingling Jia, Rong Guo, Jiachao Xiong, Hua Jiang.
       Background: Women undergo breast augmentation surgery for a variety of reasons, but surgical complications can seriously affect patient outcomes and quality of life, making it a hot research topic. Although a large body of literature exists in this field, a lack of systemic generalization hinders the ability to guide clinical practice. We aimed to identify the current research hotspots and common surgical approaches of breast augmentation and to predict future research hotspots by analyzing the literature of the past 10 years.
    Methods: All relevant literature on breast augmentation complications were screened in the Web of Science (WoS) platform from 2011 to 2021. We analyzed the research within this field using the software programs VOSviewer and CiteSpace.
    Results: In total, 2,798 publications were selected. The United States ranked first in the world (1,173 articles), followed by Italy (243 articles), and the United Kingdom (208 articles). Memorial Sloan Kettering Cancer Center was the institution with the most publications, but the academic achievements of Harvard were the most recognized. Plastic and Reconstructive Surgery was the most prominent of all journals in terms of both the number and quality of the articles published. Albornoz was the hub author in the co-citation network. Keyword cluster analysis showed that capsular contracture, breast cancer, and postoperative nausea, among others, were the hotspots and trends of research in recent years.
    Conclusions: This study comprehensively summarized and analyzed the research trends of breast augmentation complications worldwide. Capsular contracture and postoperative nausea are current research hotspots. Periareolar incision and the breast crease incision are the most common incision approaches. Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a future research hotspot.

    Exploring frailty and its domains - Systematic mapping of the literature.
    T B Pritish Baskaran, Manoj Kumar Gupta, Pankaja Raghav, K H Naveen, Akhil Dhanesh Goel.
       Background: 'Frailty' has no consensual definition till date, although the term occupies a pivotal role in geriatric medicine. A bibliometric analysis of the literature serves to capture the keyword cooccurrences and linkages, co-citations, author collaborations, research trends and to present the extant research in a nutshell.
    Objective: To explore the usage of frailty, its domains in medical research and the evolution of the term to other disciplines through systematic mapping by bibliometric analysis.
    Methods: Literature search was done in the Scopus database using a pre-formed search strategy. 2629 documents were retrieved. Co-occurrence citation analysis using keywords and link strength was obtained using the VOSviewer ver.1.6.16. A three-field plot was constructed using 'biblioshiny' package of the R-studio to identify the various domains of frailty. Descriptive statistics were applied to identify the trends in frailty research, number of contributions from countries, fields of research involving frailty.
    Results: Total of 3739 publications were observed, with the USA having most number of contributions (740, 20%) as single country, while India has only 19 contributions (0.5%) in the past 20 years. As a region, Europe and Central Asia contributed to the maximum (1714, 46.4%), most of them being from the high-income countries. Research on frailty has steadily increased over the past two decades, with most of the researches being conducted in the fields of Medicine, Biochemistry and Genetics. Cooccurrence citations and three-field plots indicate the evolving usage of frailty in other domains, such as cognition, mental health, indicators of survival, risk assessment, mortality, and quality of life.
    Conclusion: Upon exploring frailty, it also makes one wonder if frailty could be the cause for what is known as death due to 'natural causes' or 'old age'. The implementation of extension codes in the ICD-11 related to 'Ageing' (XT9T) and 'Old Age' (MG2A), paves way for researchers to further explore 'frailty' as a cause of mortality.

    The Studies on Chitosan for Sustainable Development: A Bibliometric Analysis.
    Weng Siew Lam, Weng Hoe Lam, Pei Fun Lee.
      Chitosan is a biocompatible polymer with vast applications in pharmacology, medicine, paper making, agriculture, and the food industry due to its low toxicity. Chitosan also plays an important role in the sustainable environment since chitosan is able to absorb greenhouse gases, harmful organic matter, and heavy ions. Therefore, this paper conducts a bibliometric analysis of chitosan for sustainable development using the Scopus database from 1976 to 2023. A performance analysis on the 8002 documents was performed with Harzing's Publish or Perish. Science mapping was conducted using VOSviewer. The annual publication on chitosan for sustainable development showed an upward trend in recent years as the annual publication peaked in 2022 with 1178 documents with most of the documents being articles and published in journals. Material science, chemistry, and engineering are tightly related subject areas. China had the highest publication of 1560 total documents while the United States had the most impactful publication with 55,019 total citations, 68.77 citations per document, 77.6 citations per cited document, h-index 110, and g-index of 211. India had the largest international collaboration with 572 total link strength. "International Journal of Biological Macromolecules", "Carbohydrate Polymers", and "Polymers" have been identified as the top three source titles that publish the most documents on chitosan for sustainable development. The emerging trends in chitosan on sustainable development focus on the application of chitosan as an antibacterial agent and biosorbent for contaminants, especially in water treatment.

    Global trends in the health economics field of PD-1/PD-L1 inhibitors: A bibliometric and visualized study.
    Sicen Lai, Licong Xu, Liang Zhang, Lanyuan Peng, Yixin Li, Yuancheng Liu, Nianzhou Yu, Wangqing Chen, Kai Huang.
      Inhibitors of programmed cell death protein 1 and its associated ligand (PD-L1) are widely used in cancer treatment. However, medical costs and benefits of PD-1/PD-L1 inhibitors need attention owing to differences in response rates among individuals. This study explored global trends in the health economics field of PD-1/PD-L1 inhibitors to enhance their worldwide development. Bibliometric analysis of all documents currently indexed in Web of Science Core Collection from inception to 2022 was performed. Publication year, authors, countries, institutes, and journals were analyzed by Bibliometrix package (version 3.2.1) in R (version 4.1.3). CiteSpace (version 6.1.R6) and VOSviewer (version 1.6.18) were used to analyze burst words, co-authorship of institutes, co-cited journals, and co-cited references, while figures were mainly drawn by Ggplot2 package (version 3.3.5) in R (version 4.1.3) and SCImago Graphica Beta (version 1.0.23). A total of 2020 documents related to the health economics of PD-1/PD-L1 inhibitors were identified, and 1,204 documents met the selection criteria for inclusion in the study. A rapid increase in the number of publications since 2019 was observed, but this increase stopped in 2022, revealing research saturation in the field. Value in Health (166 publications, 13.79% of total documents) had the most publications, while New England Journal of Medicine (2,890 co-citations) was the most co-cited journal. The United States was the leading contributor in this field with 506 publications and the top two productive institutes globally. The main hot topics included the cost-effectiveness of treatment with PD-1 and/or PD-L1 inhibitors, and the comparison between the cost-effectiveness of PD-/PD-L1 inhibitors and other drugs. There were substantial differences between developed and developing countries in the health economics field of PD-1 and/or PD-L1 inhibitors. The cost-effectiveness analysis of combined treatment with PD-1/PD-L1 inhibitors and other drugs warrants further attention. Findings from this study may provide governments and pharmaceutical companies with a strong reference for future research.

    Mapping and visualizing of research output on waste management and green technology: A bibliometric review of literature.
    Syed Abdul Rehman Khan, Muhammad Tabish, Zhang Yu.
      The transition to a circular economy (CE) and environmental protection highly depends on waste management (WM) and green technology (GT). The purpose of this study is to examine the past two decades of WM and GT research to identify the most significant advancements and potential future research areas. Bibliometrics content analysis and text mining were utilized to resolve the subsequent issues: Has WM and GT research developed over time in the CE industry? Does WM and GT research have a clearly defined purpose? How do you foresee the future of WM and GT research in the context of CE evolving? Consequently, 1149 journal articles from the Scopus database were used to create and evaluate bibliometric networks. Therefore, five significant CE-related issues requiring additional research were identified: The first category is bio-based WM, followed by CE transition, GT, ecological impacts, municipal solid WM and lifecycle assessment, and finally, bio-based WM. Future research topics and a tool for the CE transition may be impacted by the investigation of inclusive WM systems, GT practices and their defining highlight patterns (which aim to minimalize waste generation). Future research goals include reducing waste and implementing WM into the CE framework.

    Gregorio González-Alcaide, Marouane Menchi-Elanzi, Máxima Bolaños-Pizarro, Félix Gutiérrez-Rodero, José-Manuel Ramos-Rincón.
       INTRODUCTION: The establishment of the Spanish AIDS Research Network (RIS) was a milestone for the promotion of HIV research in Spain. We analyse Spanish HIV research, assessing the role that RIS has played in it.
    METHODS: We identified publications on HIV-AIDS with the participation of Spanish institutions in the Web of Science over the period 2010-2019, characterising research activity by means of bibliometrics and identifying the thematic areas of research through a cluster analysis.
    RESULTS: A total of 3960 documents have been identified (average of 396 documents/year), 42% of which have been signed in international collaboration. RIS researchers have participated in 60% of the documents, presenting a scientific production and citation significantly higher than authors not linked to the RIS. Five thematic clusters articulate the research, focusing on the clinical and therapeutic approach to people living with HIV, co-infection and co-morbidity with other diseases, the genetic characterisation of the virus, the development of vaccines and the study of its transmission in specific groups or associated with sexual behaviour.
    CONCLUSION: Spanish HIV research, largely driven by RIS groups, has reached a stage of maturity, with a notable increase in scientific production, participation in international cooperative networks and an outstanding impact and visibility.

    Trends in mitochondrial unfolded protein response research from 2004 to 2022: A bibliometric analysis.
    Zelin Ye, Ruoning Chai, Yujie Luan, Yihang Du, Wenjing Xue, Shuqing Shi, Huaqin Wu, Yi Wei, Limei Zhang, Yuanhui Hu.
      The mitochondrial unfolded protein response (UPRmt) is a stress response pathway that regulates the expression of mitochondrial chaperones, proteases, and other proteins involved in protein folding and degradation, thereby ensuring proper mitochondrial function. In addition to this critical function, the UPRmt also plays a role in other cellular processes such as mitochondrial biogenesis, energy metabolism, and cellular signaling. Moreover, the UPRmt is strongly associated with various diseases. From 2004 to 2022, there has been a lot of interest in UPRmt. The present study aims to utilized bibliometric tools to assess the genesis, current areas of focus, and research trends pertaining to UPRmt, thereby highlighting avenues for future research. There were 442 papers discovered to be related to UPRmt, with the overall number of publications rising yearly. International Journal of Molecular Sciences was the most prominent journal in this field. 2421 authors from 1,402 institutions in 184 nations published studies on UPRmt. The United States was the most productive country (197 documents). The top three authors were Johan Auwerx, Cole M Haynes, and Dongryeol Ryu. The early focus of UPRmt is "protein." And then the UPRmt research shifted from Caenorhabditis elegans back to mammals, and its close link to aging and various diseases. The top emerging research hotspots are neurodegenerative diseases and metabolic diseases. These findings provide the trends and frontiers in the field of UPRmt, and valuable information for clinicians and scientists to identify new perspectives with potential collaborators and cooperative countries.

    Bibliometric Analysis of Poor Oral Health as a Risk Factor for Oral Cancer.
    Amit V Mahuli, Vidya Sagar, Vedha Vpk, Simpy A Mahuli, Anit Kujur.
      Poor oral health is a risk factor for oral cancer, and bibliometrics can tell us important things about publication trends and research. Oral cancer risk factors include smoking, betel nut chewing, alcohol consumption, trauma from sharp teeth, chronic infections, and other factors related to oral health. There is a need to understand the role of poor oral health as a risk factor. Thus, this study aimed to conduct a bibliometric analysis of the literature on poor oral health as a risk factor for oral cancer. A bibliometric analysis was conducted for poor oral health as a risk factor for oral cancer using RStudio 2021.09.0+351 "Ghost Orchid" Release (2021-09-20) for Windows, package "bibliometrix." The literary data for this study were derived from Elsevier's Scopus database, and the data were exported in BibTex format. The results considered the time frame of 1983 to 2022, with journals, books, newspaper articles, and others as sources, accounting for a total of 543 documents. The search yielded a total of 2,882 authors, with a total of 3,306 appearances. The results show that the research on poor oral health and oral cancer is mainly led by the United States (106), India (49), and China (46). The top author is Warnakulasuriya S, followed by Worthington HV. The research shows the countries that are currently working on the topics and helps set up future collaborations to improve the evidence produced and help the scientific community by finding research gaps and experts in this area of research.

    Comparative Analysis of Central Asian Publication Activity Using SCImago Journal & Country Rank Data in 1996-2021.
    Burhan Fatih Kocyigit, Ahmet Akyol, Makhmadshokh K Gulov, Marlen Yessirkepov.
       BACKGROUND: Central Asian countries (CACs) are less visible in the global scientific environment, despite their solid scientific nature. The current article aimed to assess the publication productivity of CACs since 1996 using SCImago Journal & Country Rank (SJR).
    METHODS: This is a descriptive study. The SJR portal was used to retrieve the data. The Country Rankings section was viewed, and the Asiatic Region option was chosen. The most active countries and CACs' number of documents, number of citable documents, citations, self-citations, citations per document, and H index data were obtained. The number of documents from CACs was recorded annually to determine the ten-year trend (2012 to 2021). Scientific categories in which CACs were prolific were defined.
    RESULTS: Between 1996 and 2021, 18,336,647 documents with Asian region origins were produced. The most active countries in the Asiatic Region were China (1st), Japan (2nd), India (3rd), South Korea (4th), and Taiwan (5th). According to the number of documents, Kazakhstan ranked 15th, Uzbekistan 19th, Kyrgyzstan 24th, Tajikistan 27th, and Turkmenistan 31st among the Asiatic Region countries. The total number of documents originating from CACS, which was 1,616 in 2012, increased to 9,780 in 2021 with an upward trend (6.05 fold increase).
    CONCLUSION: Despite a rising number of articles, CACs are not at the forefront of scientific productivity in the Asiatic Region. Kazakhstan is the leading country in scientific productivity among CACs. Nonetheless, the increasing quantity of articles from CACs over the last ten years suggests that these countries have the infrastructure and human resources to enhance scientific research and production.

    Analysis of the Development Trend in Forensic Odontology Based on CiteSpace.
    Hao-Tian Ma, Hua-Ye Xiong, Ye Lu, Bing Li, Jiang-Hua Lai.
       OBJECTIVES: To realize the dynamic visualization of forensic odontology based on the bibliometrics methods, and capture the research hotspots and identify the future development trend.
    METHODS: Literature articles published from January 1995 to December 2020 were searched according to specific subject words in the core data set of Web of Science. The visualization analysis of publishing country, institution, discipline, author, co-cited journal and keywords was performed by CiteSpace 5.7.R5W software.
    RESULTS: The annual analysis of publications showed an upward trend of forensic odontology research literature year by year, with the number of annual publications more than 110 in the last five years. Developed countries were the main source of contributions and the average centrality was greater than 0.2. The research of forensic odontology involved multiple disciplines, including stomatology, biology, computer science and medical imaging, with a distinct interdisciplinary feature. A total of 115 nodes were obtained by keyword cluster analysis. The principal line of forensic odontology mainly included individual identification and age estimation and the emergence of hotspots was closely related to new technologies. Population-based odontology investigation, improvement of traditional dental age estimation method and dental age estimation based on new technology were popular research in forensic odontology.
    CONCLUSIONS: Developing countries urgently need to increase the focus on related research. It may be an important direction for the development of forensic odontology to establish and enrich the regional dental database, develop new odontology identification technology combined with frontier and high-end technology, and develop the identification program based on advanced information technology.

    A bibliometric analysis of media coverage of mental disorders between 2002 and 2022.
    Lei Gu, Hongwei Ding.
       PURPOSE: Mental disorders are a public health concern with media as a primary source of information. This study aims to present current research on how the media reports mental disorders.
    METHODS: This study conducted a bibliometric analysis of 130 published studies on media coverage of mental disorders, focusing on the research themes and research trends of the published studies.
    RESULTS: The results show that media coverage of mental disorders was generally negative and influenced by socio-demographic factors (e.g., age, gender, and cultural values). Results also show that social media was becoming crucial for mental health communication.
    CONCLUSION: Media worsen the stigma against those with mental disorders, continuing prejudice and discrimination. The field has shifted from traditional media to social media, and from general to specific mental disorder descriptions.

    Tropical Animal Health and Production: a 55-year bibliographic analysis setting the course for a globalized international reference journal.
    Concepta McManus, Felipe Pimentel, André M de Almeida, Daniel Pimentel.
      In this paper, we carried out a bibliographic mapping analysis with data from Scopus on publications in Tropical Animal Health and Production (TAHP) from its creation. This analysis is important for the journal and its readership, as a self-evaluation in terms of the scope and impact of the journal and how it is changing as well as aiding the editors in shaping the future direction of the journal. A total of 6229 papers were found, with an average of 8.71 citations per paper. Article Influence, Percentage of papers in Open Access, Immediacy Index, and Journal Impact Factor have all risen in recent years, although improvements are still necessary. With a cited half-life of 7.2 years, the percentage of papers in international collaboration has stabilized since 2010 (around 40%), down from around a peak of 60% in 2006. The journal is a Q2 journal with 86.4% of its documents cited. Of all documents published, 2401 were classified in SDG3 (Good Health and Wellbeing) followed by SDG2 (Zero Hunger) with 136. We mapped citations, co-citations, and bibliographic coupling and identified major authors, sources, references, and countries publishing in TAHP. The journal continues to play a key role in advancing knowledge and understanding of animal health and production in tropical and sub-tropical regions and supporting the development of sustainable animal production and veterinary medicine in these vast regions of the globe.

    Neuro-ophthalmology output in high-impact clinical ophthalmology and neurology journals.
    Jim S Xie, Irina Sverdlichenko, Jonathan A Micieli, Edward Margolin.
       OBJECTIVE: To characterize the neuro-ophthalmology publishing trends of the top general clinical ophthalmology and neurology journals and to report (i) the proportion of articles that are neuro-ophthalmology focused and (ii) the correlation between annual proportion of neuro-ophthalmology-focused articles and annual proportion of neuro-ophthalmologist journal editors.
    DESIGN: Retrospective database review.
    MATERIALS: Articles in the top 5 general clinical ophthalmology and neurology journals.
    METHODS: Publications from 2012 through 2021 were retrieved from Embase and classified as teaching or nonteaching articles based on journal indexing. Duplicate screening was conducted to further categorize articles as either focused or not focused on neuro-ophthalmology.
    RESULTS: The titles, abstracts, and (or) full texts of 34,660 articles were reviewed. The total proportions of nonteaching articles and teaching articles focused on neuro-ophthalmology were 3.4% and 13.8%, respectively. Neuro-ophthalmology contributions to nonteaching and teaching publications were greater among the ophthalmology journals (4.0% and 15.2%) than among the neurology journals (2.6% and 13.3%). There were no clear trends in the annual proportion of neuro-ophthalmology-focused articles across the 10-year period. The annual proportion of neuro-ophthalmologist journal editors was positively correlated with annual neuro-ophthalmology output for teaching articles (Pearson's r = 0.541; p < 0.001) but not articles unrelated to teaching (Pearson's r = 0.067; p = 0.598).
    CONCLUSIONS: Our study found that there was a lower prevalence of neuro-ophthalmology papers in high-impact-factor general clinical ophthalmology and neurology journals over the last 10 years. It is important to have good representation of neuro-ophthalmology studies in such journals to promote best neuro-ophthalmic practices among all clinicians.

    Raanan Meyer, Sadikah Behbehani, Kaylee Brooks, Cristobal R Valero, Courtney Fox, Alyssa N Small Layne, Meenal Misal, Peter R Movilla, Jacob K Lauer, Adriana J Wong, Kathleen Ackert, Mireille Truong.
       STUDY OBJECTIVE: To study the impact of a Twitter-based gynecologic surgery journal club of articles published in the Journal of Minimally Invasive Gynecology (JMIG) on their social media attention and citation scores.
    DESIGN: Cross sectional study.
    SETTING: N/A.
    PATIENTS: N/A.
    INTERVENTIONS: Comparison of citation and social media attention scores was conducted for all articles presented in the JMIG Journal Club (#JMIGjc), a monthly scientific discussion on Twitter of JMIG selected articles, between 3/2018- 9/2021 (Group A), with two matched control groups of other JMIG articles; Group B- articles mentioned on social media but not promoted in any JMIG social media account; Group C- articles with no social media mentions and not presented in #JMIGjc. Matching was performed for publication year, design, and topic in a 1:1:1 ratio. Citation metrics included number of citations per year (CPY) and relative citation ratio (RCR). Altmetric Attention Score (AAS) was used to measure social media attention. This score tracks research articles' online activity from different sources such as social media platforms, blogs, and websites. We further compared Group A to all JMIG articles published during the same period (Group D).
    MEASUREMENTS AND MAIN RESULTS: Thirty-nine articles were presented in the #JMIGjc (Group A) and were matched to 39 articles in Groups B and C. Median AAS was higher in Group A compared to Groups B and C (10.00 vs. 3.00 vs. 0, respectively, p<0.001). CPY and RCR were similar between groups. Median AAS was higher in Group A compared to Group D (10.00 vs. 1.00, p<0.001), as were median CPY and RCR (3.00 vs.1.67, p=0.001; 1.37 vs. 0.89, p=0.001, respectively).
    CONCLUSION: Although citation metrics were similar between groups, #JMIGjc articles had higher social media attention metrics than matched controls. Compared to all publications within the same journal, #JMIGjc articles resulted in higher citation metrics.

    The long COVID research literature.
    Alan L Porter, Mark Markley, Nils Newman.
      While the COVID-19 pandemic morphs into less malignant forms, the virus has spawned a series of poorly understood, post-infection symptoms with staggering ramifications, i. e., long COVID (LC). This bibliometric study profiles the rapidly growing LC research domain [5,243 articles from PubMed and Web of Science (WoS)] to make its knowledge content more accessible. The article addresses What? Where? Who? and When? questions. A 13-topic Concept Grid presents bottom-up topic clusters. We break out those topics with other data fields, including disciplinary concentrations, topical details, and information on research "players" (countries, institutions, and authors) engaging in those topics. We provide access to results via a Dashboard website. We find a strongly growing, multidisciplinary LC research domain. That domain appears tightly connected based on shared research knowledge. However, we also observe notable concentrations of research activity in different disciplines. Data trends over 3 years of LC research suggest heightened attention to psychological and neurodegenerative symptoms, fatigue, and pulmonary involvement.

    Modern Impact of Surgery Journals: Associations Between Impact Factor, H5-Index, and Altmetric Score.
    Russell Seth Martins, Nabil Wasif.
       INTRODUCTION: While impact factor (IF) remains the "gold standard" metric for journal quality, newer metrics are gaining popularity. These include the H5-index and journal Altmetric Attention Score (AAS). We explored the relationship between the IF, H5-index, and AAS for core general surgery (GS) and subspecialty journals.
    METHODS: For all GS and subspecialty journals with a Clarivate IF, H5-index (January 1, 2017, to December 31, 2021) and journal AAS were obtained. Journal Twitter presence and activity was sourced from Twitter and the Twitter application programming interface. Spearman's correlations were assessed for numeric variables.
    RESULTS: A total of 105 journals were included, around half (49/105; 46.7%) of which were core GS journals. Median IF was 2.48 and median H5-index 19. Journal IF demonstrated a strong correlation with H5-index overall (r = 0.81), though this ranged from r = 0.95 (P < 0.01) for vascular surgery to r = 0.77 (P < 0.01) for plastic surgery journals. AAS was moderately correlated with the IF and H5-index (r = 0.59 and 0.62, respectively; both P < 0.01). R2 values ranging indicated that 66% of the variation in the H5-index and 35% of the variation in AAS was explained by the IF. Just over half the journals had a Twitter account (54/105; 51.4%). Journals with a Twitter account also had a significantly higher IF, H5-index, and AAS than those without a Twitter account (all P < 0.01). AAS was moderately correlated with Twitter activity (r = 0.59) and Twitter followers (r = 0.69).
    CONCLUSIONS: Across GS and subspecialty journals, journal IF correlates strongly with the H5-index and moderately with AAS. However, only 35% of variation in AAS and 66% of variation in the H5-index is explained by the IF, indicating that these metrics measure unique aspects of journal quality. The future growth of surgical journals should be geared towards improving across multiple metrics, including both the conventional and the contemporary, while leveraging social media to improve readership and eventual academic impact.

    Early Career Publication Trajectory of Male Infertility Fellows During and After Fellowship.
    Jesus Perez, Benjamin Plambeck, Christopher M Deibert.
       BACKGROUND: Improving evidence-based medicine through research contribution is an important aspect of fellowship training. Prior studies have investigated the research activity of urology fellows during and after fellowship. The main objective of this study was to specifically explore the publication productivity of male infertility fellows both during fellowship and in the first 5 years afterwards.
    METHODS: The 19 fellowship program directors from the Society for the Study of Male Reproduction were asked to share a list of fellows from 2004 to 2019. Publications from 87 fellows at 12 programs were analyzed. PubMed® was utilized to search for peer-reviewed publications for each fellow during their fellowship and in the first 5 years afterwards. Each publication was classified by publication type (original research, review article, editorial comment, or case report), topic (fertility, testosterone, or other), and author type (sole, first, middle, or last author).
    RESULTS: Some 87 male infertility fellows were analyzed, and a total of 1608 peer-reviewed publications were identified. Some 662 total publications (41.2%) were written on the topic of fertility during fellowship and in the first 5 years afterwards. Some 554 (34.5%) publications were completed during fellowship, 178 (11.1%) in year 1, 164 (10.2%) in year 2, 220 (13.7%) in year 3, 269 (16.7%) in year 4, and 223 (13.9%) in year 5. The mean number of publications during fellowship was 6.37 (range 0-57). Means for years 1-5 after fellowship were 2.12, 1.95, 2.65, 3.36, and 2.97, respectively. After fellowship, 25.3% of the fellows did not publish again. A significant difference was detected between the group mean number of publications (analysis of variance, ANOVA - p = 0.0001) during fellowship and the 5 years afterwards. There was no significant difference between the group mean number of publications between the 1st and 5th years post-fellowship (ANOVA - p = 0.5919).
    CONCLUSIONS: As anticipated, male infertility fellows were most productive during fellowship, with relatively stable research production thereafter. Thus, early career support and mentorship remain important to the future academic success of fellows. Future investigation of the relationship between male infertility fellow characteristics and the pursuit of an academic career is warranted.

      A scientometric analysis was conducted to investigate the trends and development of crayfish research in terms of literature published, author, affiliation, and countries' collaborative networks, as well as the co-citation dataset (e.g., author, article, and keywords). The study analyzed 12,039 bibliographic datasets from the Web of Science, using CiteSpace as a tool for the co-citation analysis. The study revealed extraordinary increases in publication trends, with a total of 21,329 authors involved in approximately 80% of countries around the world (163/195) having conducted crayfish research. Unsurprisingly, countries such as the USA and China, followed by European countries, were among the top countries that have published crayfish-related studies. The findings also indicated that "invasive crayfish" was the world's top keyword for crayfish research. Crayfish species are important for both environmental sustainability (invasiveness and species composition) and social wellbeing (aquaculture), which provides directions for research, philanthropic, academic, government, and non-government organizations regarding how to invest limited resources into policies, programs, and research towards the future management of this species. Our study concluded that strategic collaboration among authors, institutions, and countries would be vital to tackle the issue of invasive crayfish species around the world.

      Promotion in academia heavily relies on research productivity. The h-index is a standardized metric used to quantify research productivity at the individual level. We evaluated factors associated with h -index in dermatology across select Canadian academic centers with special focus on sex and academic rank. Medical academic centers throughout Canada with dermatology training programs were included. For each faculty member, we extracted the following data from public sources: sex, graduate degree, academic rank, years since the Fellow of the Royal College of Physicians and Surgeons of Canada (FRCPC) certification or equivalent, recent Canadian Institutes of Health Research (CIHR) funding and H-index (based on Scopus author profile). Log-linear univariate and multivariate regression analyses were performed to evaluate the association between h-index and these factors. An ordinal logistic regression was performed to explore sex differences in academic ranking. Our results showed that out of 300 faculty members across Canada, 155 were females (51.67%) and 145 were male (48.33%). H-index was available for 279 dermatologists. The average h-index was 8.35 (SD 11.53) and the median was 4.00 (1st quartile = 2.00, 3rd quartile = 10.00). Higher h-index was associated with more years since dermatology certification, successive academic rank, graduate degree and recent CIHR funding, but not with sex. In conclusion, h-index was not associated with sex when controlling for potential confounders. These results could reflect recent demographic changes in the field with an increase in newly appointed female dermatologists. Longitudinal assessment of academic productivity in dermatology is needed to assess the impact of continued efforts to promote equal opportunities in the field.

    Gender differences of authors of major Hepatology society guidelines during the past 15 years.
    Xiaowei Tang, Bei Luo, Shu Huang, Jiao Jiang, Yuan Chen, Xiaomin Shi, Wei Zhang, Lei Shi, Xiaolin Zhong, Muhan Lü.
       BACKGROUND AND OBJECTIVE: Recent studies have shown that women are underrepresented as authors of medical research and clinical practice guidelines. This study aimed to evaluate gender disparities of authors of major hepatology guidelines.
    METHODS: We reviewed the hepatology guidelines published by the following major gastroenterology societies from January 2008 to September 2022: the American Gastroenterological Association (AGA), American College of Gastroenterology (ACG), American Association for the Study of Liver Diseases (AASLD), Asian-Pacific Association for the Study of the Liver (APASL), British Society of Gastroenterology (BSG), European Association for the Study of the Liver (EASL) and Korean Association for the Study of the Liver (KASL). We determined the topic and the gender of all authors of each guideline. The numbers of men authors, women authors and total authors were collected. The trends of women first authors, women senior authors and total women authors were assessed. A logistic regression analysis was performed to analyse the relationship between the gender of the first or senior author and related factors.
    RESULTS: We identified 103 hepatology guidelines published between January 2008 and September 2022 published by the AGA, ACG, AASLD, APASL, BSG, EASL, and KASL. The gender of 1096 of 1100 (99.6%) authors was determined. Therefore, a total of 1096 authors were included: 223 (20.3%) authors were women and 873 (79.7%) authors were men. Women comprised 14.6% of all first authors, and 20.4% of all senior authors were women. Only the AASLD had writing committees comprising more than 30% total women authors. The proportions of women senior authors and total women authors increased significantly during the study period (p < .05). Women first authors and women senior authors were more likely to publish guidelines with more women authors. Women first authors were less likely to be co-authors with men authors.
    CONCLUSIONS: Over the course of the past decade, the proportion of women authors of major hepatology guidelines has been low; however, this gender gap appears to be closing.

    Understanding the research on tracking, diagnosing, and intervening in sleep disorders using mHealth apps: Bibliometric analysis and systematic reviews.
    Mingfu Nuo, Hongjuan Fang, Tong Wang, Jun Liang, Yunfan He, Hongbin Han, Jianbo Lei.
       Objectives: In solving the global challenge of sleep disorders, Mobile Health app is one of the important means to monitor, diagnose, and intervene in sleep disorders. This study aims to (1) summarize the status and trends of research in this field; (2) assess the production and usage of sleep mHealth apps; (3) calculate the conversion rate of grants that the proportion of newly developed apps from being funded and developed to published on application stores.
    Methods: Using bibliometric and content analysis methods, based on "Research Paper-Product Output-Product Application" chain and considering the "Research Grants" of articles, we conducted a systematic review of eight databases, to identify relevant studies over the last decade.
    Results: Over the past decade, 1399 authors published 313 papers in 182 journals and conferences. The number of publications increased with an average annual growth of 41.6%. The current focus area is research using cognitive behavioral therapy to intervene in sleep. Sleep-staging tracking is a shortcoming of this field. A total 368 sleep mHealth apps (233 newly developed and 135 existing) were examined in 313 papers; 323 grants supported 178 articles (56.9%). Only 12 of the newly developed apps are used in the real world, resulting in a 9% grant conversion rate.
    Conclusions: In the last decade, the field of tracking, diagnosing, and intervening in sleep disorders using mHealth apps has shown a trend of rapid development. However, the conversion rate of products from being funded and developed for use by end-users is low.

    Translating Scientific Discovery Into Health Policy Impact: Innovative Bibliometrics Bridge Translational Research Publications to Policy Literature.
    Nicole M Llewellyn, Amber A Weber, Clara M Pelfrey, Deborah DiazGranados, Eric J Nehl.
      To understand how translational science efforts lead to outcomes, it is common to examine publications as a key step in the translational process. The National Institutes of Health's Clinical and Translational Science Awards (CTSA) program aims to accelerate that process by providing support to investigators. Although it is challenging to measure the impact of such support on translational outcomes, CTSA-supported research that arises in research publications can advance translation through use of these publication in public policy and guideline documents from government health agencies, intergovernmental organizations, and other outlets. Using cutting-edge bibliometric tools, the authors evaluated how CTSA-supported research has extended its impact beyond academic silos to influence public policy literature. The authors identified approximately 118,490 publications that acknowledged receiving support from a CTSA hub, from the inception of the program in 2006 through 2021. Articles were queried in the Overton policy database, which indexes references to publications in global policy literature. The search revealed 13% of CTSA-supported articles were referenced in policy documents, significantly more than the expected proportion (10%) calculated by Overton. References came from 576 policy source outlets across 87 countries, predominantly the United States and Europe. The most frequent sources included guidelines in PubMed Central, the World Health Organization, and the Centers for Disease Control and Prevention. The authors illustrate the bridge from translational research to public policy with case studies of 6 articles based on CTSA-supported research and having notable policy impact. They found articles with greater clinical relevance, altmetric attention (i.e., nonacademic community/public attention), and academic citation influence were more likely to be referenced in policy literature. Study findings help to characterize the kinds of research that have influenced and may be expected to influence health policy in the future.

    COVID-19 retracted publications on retraction watch: A systematic survey of their pre-prints and citations.
    Zainab Syed, Fatema Syed, Lehana Thabane, Myanca Rodrigues.
       Background: Studies related to the coronavirus disease 2019 (COVID-19) were frequently published as pre-prints prior to undergoing peer-review. However, several publications were later retracted due to ethical concerns or study misconduct. Although these studies have been retracted, the availability of their corresponding pre-prints has never been formally investigated, and may result in the spread of misinformation if they are being used to inform decision-making.
    Methods: Our objective was to conduct a systematic survey of retracted COVID-19 publications listed on the Retraction Watch database as of August 15th, 2021. We assessed the availability of corresponding pre-prints for retracted publications, and documented the number of citations and online views.
    Results: Our study included 140 retracted COVID-19 publications, and we could not retrieve corresponding pre-prints for 132 retracted publications in our study (94%). Although we were unable to find the majority of pre-prints, they had already been disseminated, with a maximal citation count of 593 and Altmetric score of 558,928.
    Conclusion: While it is reassuring that most corresponding pre-prints could not be retrieved, our study highlights the need for online platforms and journals to employ quality assurance methods to prevent the spread of misinformation through citation of retracted papers.

    The research foundation for COVID-19 vaccine development.
    Komi S Messan, Pawel P Sulima, Dolan Ghosh, Jonathan Nye.
      The development of effective vaccines in <1 year to combat the spread of coronavirus disease 19 (COVID-19) is an example of particularly rapid progress in biomedicine. However, this was only made possible by decades of investment in scientific research. Many important research commentaries and reviews have been provided to describe the various contributions and scientific breakthroughs that led to the development of COVID-19 vaccines. In this work, we sought to complement those efforts by adding a systematic and quantitative study of the research foundations that led to these vaccines. Here, we analyzed citations from COVID-19 vaccine research articles to determine which scientific areas of study contributed the most to this research. Our findings revealed that coronavirus research was cited most often, and by a large margin. However, significant contributions were also seen from a diverse set of fields such as cancer, diabetes, and HIV/AIDS. In addition, we examined the publication history of the most prolific authors of COVID-19 vaccine research to determine their research expertise prior to the pandemic. Interestingly, although COVID-19 vaccine research relied most heavily on previous coronavirus work, we find that the most prolific authors on these publications most often had expertise in other areas including influenza, cancer, and HIV/AIDS. Finally, we used machine learning to identify and group together publications based on their major topic areas. This allowed us to elucidate the differences in citations between research areas. These findings highlight and quantify the relevance of prior research from a variety of scientific fields to the rapid development of a COVID-19 vaccine. This study also illustrates the importance of funding and sustaining a diverse research enterprise to facilitate a rapid response to future pandemics.

    Study on bioactive compounds of microalgae as antioxidants in a bibliometric analysis and visualization perspective.
    Ning Yang, Qingyang Zhang, Jingyun Chen, Shilin Wu, Ran Chen, Liping Yao, Bailei Li, Xiaojun Liu, Rongqing Zhang, Zhen Zhang.
      Natural antioxidants are more attractive than synthetic chemical oxidants because of their non-toxic and non-harmful properties. Microalgal bioactive components such as carotenoids, polysaccharides, and phenolic compounds are gaining popularity as very effective and long-lasting natural antioxidants. Few articles currently exist that analyze microalgae from a bibliometric and visualization point of view. This study used a bibliometric method based on the Web of Science Core Collection database to analyze antioxidant research on bioactive compounds in microalgae from 1996 to 2022. According to cluster analysis, the most studied areas are the effectiveness, the antioxidant mechanism, and use of bioactive substances in microalgae, such as carotene, astaxanthin, and tocopherols, in the fields of food, cosmetics, and medicine. Using keyword co-occurrence and keyword mutation analysis, future trends are predicted to improve extraction rates and stability by altering the environment of microalgae cultures or mixing extracts with chemicals such as nanoparticles for commercial and industrial applications. These findings can help researchers identify trends and resources to build impactful investigations and expand scientific frontiers.

    An overview and trend analysis of research on the relationship between urban streets and residents' health in China pre- and post COVID-19 pandemic.
    Lingchao Meng, Kuo-Hsun Wen.
       Introduction: After the outbreak of COVID-19, the international community has been faced with various problems it has brought to cities. A large number of research projects and corresponding management measures were launched globally, trying to reduce the impact of COVID-19 on society. Among them, exploring how to maintain the health of residents by managing and updating the design of urban streets is one of the important issues regarding urban sustainability in the post-epidemic era.
    Methods: This study uses bibliometric analysis techniques to obtain an overview of the knowledge structure of 898 Chinese urban streets and residents' health relationship studies from the China National Knowledge Infrastructure (CNKI) database for two periods (1999-2019 and 2020-2022). Five aspects were analyzed in terms of the keyword domain co-occurrence network, topic evolution path, emergent terms, hierarchical clustering, and confusion matrix.
    Results and discussion: The findings revealed that studies focused on six broad themes: community residents, health surveys, health education, COVID-19, healthy city, and public health. Based on these findings, the paper compares and discusses research priorities before and after the outbreak and highlights areas for further research and attention.

    Study on Intestinal Flora and Asthma: Knowledge Graph Analysis Based on CiteSpace (2001-2021).
    Hang Zheng, Huan Dai, Xiumei Yan, Qiangwei Xiang.
      Asthma is a common chronic inflammatory disease of the airway. Intestinal flora, a significant risk factor for asthma, has become a widespread concern in the pathogenesis of asthma. To review the literature related to intestinal flora in asthma, summarize research direction, and report trends, this study used CiteSpace to perform bibliometric statistics and analysis on the research papers of intestinal flora and asthma collected in the Web of science core collection from 2001 to 2021. Eventually, a total of 613 articles were included. The results demonstrated that research on gut flora and asthma continued to heat up, with article numbers increasing, especially in the last decade. Moreover, analysis of the keywords showed that the research topics of intestinal flora and asthma range from confirming the link between intestinal flora and asthma to investigating mechanisms and then to asthma treatment. According to the summary of research hotspots, we expand on three emerging issues that require attention in the intestinal flora and asthma research, including (regulatory T)Treg cells, probiotics, and chain fatty acid. Evidence illustrated that Treg cells play a crucial role in the pathogenesis of asthma caused by dysbiosis of the gut flora. Furthermore, in contrast to probiotic supplements, which do not reduce the risk of developing asthma, short-chain fatty acids supplements do. Overall, the research direction in the field of intestinal flora and asthma has recently evolved from macro to micro with depth broadened. As a robust scientific evaluation, our study provided a comprehensive overview of the area, particularly for research focus, which could more precisely direct scholars on future research and clinical diagnosis, therapy, and individualized prevention.

    Zalik Nuryana, Wenbin Xu, Luky Kurniawan, Natri Sutanti, Syahdara Anisa Makruf, Indah Nurcahyati.
      This article aims to analyze the trend of publications on student stress and mental health topics during online learning as well as the potential for post-COVID-19 curriculum development. 1456 articles were analyzed by the bibliometric method. Data were obtained from the Scopus database consisting of 1382 articles, 73 review articles, 1 conference article. Based on the analysis, Li X is the most productive author with 16 documents, while in terms of the number of citations, Wang C ranks first with 3897 citations. Meanwhile the most frequently used keywords were COVID-19 (n = 862), followed by stress (n = 312), mental health (n = 260), anxiety (n = 248), and depression (n = 214). These represent the trend of publications related to the topics discussed in 2020. Moreover, alternative research themes such as online learning, higher education, sleep, loneliness, perceived stress, insomnia, emotional intelligence, and psychological resilience can be further investigated in the future. This article recommends developing a curriculum that can accommodate various issues during COVID-19 and the changing learning climate after the pandemic. The potential for post-COVID-19 school curriculum development is also discussed.

      Fast-tracking publication of original research to coincide with a conference presentation ("coordinated publication") is a mechanism of rapidly disseminating new data. How often this occurs, whether its frequency is changing, and the impact of this approach on information dissemination, is unknown. Our objective was to describe the characteristics of coordinated publications, how the practice has changed over time, and evaluate its potential impact on dissemination of study results. We conducted a cross-sectional study of randomized controlled trials published in NEJM, Lancet, and JAMA between January 1, 2015, and December 31, 2019. Among the 1533 included randomized controlled trials, 502 (33%) had coordinated publications. Coordinated publications increased from 30% [n = 94] in 2015 to 37% [n = 136] in 2019. Coordinated publications were more likely to be unblinded (61% [n = 305] vs. 52% [n = 532]) and more likely to be funded by industry (50% [n = 249] vs. 30% [n = 311]). The strongest predictor of a coordinated publication was cardiovascular disease subspecialty (OR = 3.96, 95% CI [2.95, 5.36]). The median number of citations (188 vs. 98) and the median Altmetric score (318 vs. 182) were higher for coordinated publications than non-coordinated publications. These differences persisted in a multivariable regression model. Coordinated publication is increasingly common. While coordinated publications may generate greater attention, they were observed to be more likely to be unblinded and more likely to be funded by industry, raising questions about the value and intentions of such promotion.

    A 10-Year Analysis of Representation of Women in Patent Applications and NIH Funding in Vascular Surgery.
    Helen Xun, David P Stonko, Earl Goldsborough, Alana Keegan, Tara Srinivas, Sanuja Bose, Katherine M McDermott, M Libby Weaver, Caitlin W Hicks.
       BACKGROUND: There has been an increasing focus on gender disparities in the medical field and in the field of vascular surgery specifically. We aimed to characterize gender representation in vascular surgery innovation over the past 10 years, using metrics of patents and NIH support.
    METHODS: We performed a retrospective review of all vascular-related patent filings (Google Scholar) and NIH-funded grants (NIH RePORTER) over a 10-year period (January 1st, 2012, to December 31st,2021). Gender-API was used to identify the gender of the inventors, with manual confirmation of a 10% random sample. Gender representation for patent inventors and grant Principal Investigators (PIs) were compared using Chi-squared and Student's t-tests as appropriate. Yearly temporal changes in representation were analyzed using linear regression analyses and Wilcoxon-type tests.
    RESULTS: We identified 2992 unique vascular device patents with 6093 associated inventors over 10 years. Women were underrepresented in patent authorship overall (11.5%), and were least likely to be listed as first inventor (8.9%) and most commonly fourth and fifth inventors (15.5% and 14.1%, respectively) compared to men. There was no significant change in representation of women inventors over time (-0.2% females per year, 95% CI -0.54 to 0.10). We identified 1736 total unique NIH grants, with 23.8% of funded projects having women PIs. There was an increase in the proportion of women PIs over time (+1.31% per year, 95% CI 0.784 to 1.855; P<0.001). Projects with women PIs received mean total awards that were significantly lower than projects with men PIs ($350,485 ± $220,072 vs. $451,493 ± $411,040; P<0.001), but the overall ratio of funding:investigators improved over time (+$11,531 per year, 95% CI $6,167 to $16,895; P = 0.0011).
    CONCLUSIONS: While we have made strides in increasing the number of women in the surgical research space, there is still room for improvement in funding parity. In addition, we found substantial and persistent room for improvement in representation of women in surgical innovation. As we enter a new frontier of surgery hallmarked by equalizing gender representation, these data should serve as a call-to-action for initiative aimed at rebuilding the foundation of surgical innovations upon equal gender representation.

    Oleg E Karpov, Elena N Pitsik, Semen A Kurkin, Vladimir A Maksimenko, Alexander V Gusev, Natali N Shusharina, Alexander E Hramov.
      Artificial intelligence (AI) has revolutionized numerous industries, including medicine. In recent years, the integration of AI into medical practices has shown great promise in enhancing the accuracy and efficiency of diagnosing diseases, predicting patient outcomes, and personalizing treatment plans. This paper aims at the exploration of the AI-based medicine research using network approach and analysis of existing trends based on PubMed. Our findings are based on the results of PubMed search queries and analysis of the number of papers obtained by the different search queries. Our goal is to explore how are the AI-based methods used in healthcare research, which approaches and techniques are the most popular, and to discuss the potential reasoning behind the obtained results. Using analysis of the co-occurrence network constructed using VOSviewer software, we detected the main clusters of interest in AI-based healthcare research. Then, we proceeded with the thorough analysis of publication activity in various categories of medical AI research, including research on different AI-based methods applied to different types of medical data. We analyzed the results of query processing in the PubMed database over the past 5 years obtained via a specifically designed strategy for generating search queries based on the thorough selection of keywords from different categories of interest. We provide a comprehensive analysis of existing applications of AI-based methods to medical data of different modalities, including the context of various medical fields and specific diseases that carry the greatest danger to the human population.
