    Research characteristics and trends of power sector carbon emissions: a bibliometric analysis from various perspectives.
    Ke Liang, Wenjie Li, Junhui Wen, Weikun Ai, Jiabin Wang.
      Power sector carbon emissions (PSCEs) have received an increasing attention due to their huge contribution to global greenhouse gas emissions. Herein, the research characteristics and trends of PSCEs are investigated based on bibliometric analysis. The basic growth trends, contributions of the most productive countries/territories, institutions, authors, journals, and subject categories are analyzed systematically. In addition, the major research fields and research trends are investigated by the keywords co-occurrence analysis and topic evolution. The result indicates that PSCEs research has developed rapidly in the past 20 years, and the proportion of research funding has increased from 0 at the beginning to 73% in the last 5 years. Especially, the number of scientific publications has shown an explosive growth after the signing of the Paris Agreement in 2016. The People's Republic of China (PR China), the USA, and England are the three most dynamic countries in the field of PSCEs research, with 64.8% of the total number of published papers. The most productive institutions are also from these countries. Based on keywords co-occurrence analysis, it is concluded that driving factors, prediction, impacts, and countermeasures of carbon emission are three major research fields. The result of thematic evolution indicates that the topics on energy transition, life cycle assessment, marginal abatement cost and energy policy have been the research hotspots in recent years. This study presents an worldwide overview of PSCEs research, thus helping the stakeholders to quickly grasp the research trends and conduct future work.

    Global network mapping research landscape and trends of the endogenous retroviruses: a look through bibliometric analysis.
    Gul Zaib, Hengmi Cui, Xuming Hu.
      Endogenous retrovirus (ERV) research amalgamates host-retroviral coevolutionary, phylogenomic, infection, immunity, and cellular studies in various hosts ranging from fish to humans. Henceforth, a bibliometric analysis of these publications may aid in the identification of trends in ERV research. It was the foremost bibliographic study, with the key aim to conduct the bibliometric network analysis (e.g. co-authorship, co-occurrence, citation, bibliographic coupling, and co-citation analysis) to find the most prolific authors, organizations, and countries in ERV research, based on the mapping of bibliographic data. Second, the mapping based on text data comprised to chalk out the research trend over the time. The global literature about endogenous retroviruses published between 1985 and Sep 2021 was searched in the Web of Science (Core Collection) database using the "ENDOGENOUS RETROVIRUS" keyword. The bibliometric analysis of this dataset was carried out using VOSviewer version 1.6.17. According to findings, English was the de facto language of these publications, and 2157 were original articles. Among 2939 published documents, "endogenous retrovirus" was the most frequent keyword. Moreover, it revealed the United States as a core contributor to studies on the ERV. The Journal of Virology published a substantial amount of manuscripts in ERV. Robert Koch Institute and Harvard University were leading organizations for research in this field. The application of ERV research from China could be the research hotspot to follow in the coming years. Current bibliometric analysis provides a comprehensive picture of ERV research progress and has highlighted the contribution of different stakeholders.

    Jiuzuo Huang, Yixin Sun, Zhujun Li, Yunzhu Li, Ru Zhao, Nanze Yu, Xiao Long.
       BACKGROUND: We conducted a bibliometric analysis of blepharoptosis, obtained the top 100 most-cited articles, and then researched the characteristics of every article.
    MATERIALS AND METHODS: The Web of Science Citation Index was utilized to identify articles related to blepharoptosis written in English published from 1900 to 2021 using predefined search terms. Then, the returned results were screened, and the top 100 most-cited articles were individually classified based on publication year, country of publication, source journal, total citations, authors' specialty, level of evidence, main subject, and type of study.
    RESULTS: The 100 most-cited articles were published between 1948 and 2014. The number of citations/articles ranged from 49 to 743. Ophthalmology journals made the greatest contributions to landmark literature (n=61). The primary focus of these 100 studies was the surgical technique (n=41). The majority of them (n=52) only achieved level 4 evidence, as a high proportion of these articles were case series (n=52). The most common country of publication was the United States (n=59).
    CONCLUSIONS: Our bibliometric analysis provides insight into the citation frequency of the most-cited articles on blepharoptosis. The landmark, highly cited articles that have shaped the landscape of blepharoptosis were identified. The results from these top 100 cited articles are helpful for present current surgical decision-making.

    The past, present, and future of research on neuroinflammation-induced mild cognitive impairment: A bibliometric analysis.
    Ming Cai, Yuanqi Zhang, Si Chen, Zhan Wu, Lei Zhu.
       Background: Mild cognitive impairment (MCI) is a precursor to dementia, and neuroinflammation in the brain is thought to be one of the main pathogenic mechanisms of MCI. However, the underlying neurobiological mechanisms have not been fully explored. The purpose of this study was to establish a visual model map of the articles in the field of neuroinflammation-induced MCI over the past 11 years to reveal the research hotspots and predict the future development trends in this field, which will help to promote the research and development for MCI.
    Methods: The "neuroinflammation" and "mild cognitive impairment" were used as search terms, and literature about neuroinflammation-induced MCI published between 2011 and 2021 was collected from the Web of Science. CiteSpace and VOSviewer were used to create visual model maps, and assess collaboration among different authors, countries, and institutions. Finally, the current research hotspots and future research directions were analyzed by using high-frequency keywords analysis and co-cited reference burst analysis.
    Results: A total of 226 articles were retrieved. The number of publications in neuroinflammation-induced MCI shows an upward trend. Since 2018, the number of papers published in this field has increased significantly, with an average of more than 100 published each year. The United States had the highest literature production and the number of cited journals in this research area, and the National Institute on Aging was the most productive research institution. Brooks D.J. and Heneka M.T. had the highest number of publications and had the highest frequency of co-citations. The co-cited references revealed the evolution of the research themes, and the current studies are mainly focused on the effects of various metabolites on the control of microglial activation. "Cerebrospinal fluid," "mouse model," "tau," "microglial activation," "astrocytes," and "TREM2" were the current high-frequency and emerging keywords.
    Conclusion: Research on neuroinflammation-induced MCI is burgeoning, and the close collaboration with different nations and institutions need to be further strengthened. Current research hotspots are focused on the effects of various metabolites on microglia activation. Future studies should focus on how to regulate the phenotypes of microglia and astrocyte to reduce neuroinflammation and treat MCI.

    Ebru Çağlayan Akay, Naciye Tuba Yılmaz Soydan, Burcu Kocarık Gacar.
      An extensive literature providing information on published materials in machine learning exists. However, machine learning is still a rather new concept in the fields of economics and econometrics. This study aims to identify different properties of published documents about machine learning in economics and econometrics and therefore to draw a detailed picture of recent publications from bibliometric analysis perspectives. For the aim of the study, the data are collected from the publications indexed by Web of Science and Scopus databases from the period 1991 to 2020. Inthe study, the data have been illustrated by VOSviewer for science mapping. The analysis of variance has also been used to identify the links between the number of citations of articles and years. The findings obtained provides information about the studies on machine learning in the relevant field conducted in the past, as well as providing an opportunity to gain knowledge about the researched area by shedding light on what the future research areas would be. There is no doubt that it attracts attention has increased significantly on machine learning in the field of economics and econometrics and academic publications on machine learning in the relevant field have increased over the last decade.

    Research progress of E-cigarette-A bibliometric analysis during 2010-2022.
    Shihui Hong, Feng Wu, Wang Yao, Zixuan Yang, Weiguo Wei, Zhe Han, Can Feng, Min Fan.
       Introduction: Electronic cigarettes have been widely used all over the world. It is not clear what the advantages and disadvantages of a novelty in daily life are that is attracting increasing attention. Up to now, no bibliometric studies on e-cigarettes have been published in databases. Therefore, we are willing to explore directions and research hotspots in this emerging field by using bibliometrics to analyze research areas, publishing countries and institutions, high-output authors, and future trends of e-cigarettes in recent years. Compared with the traditional review, the bibliometric study can provide some information on core journals, articles, researchers, institutions, and countries concentrating on this topic to guide experimentation strategies and funding decisions.
    Methods: A bibliometric analysis was performed by CiteSpace and VOSviewer up to April 2022 in the core collection of Web of Science. HistCite, VOSviewer, CiteSpace, and the R-based Bibliometrix 4.1.0 packages were used to analyze literature information, including year, journal, country, institute, author, keywords, and co-cited references.
    Results: Research related to e-cigarettes has proliferated since its inception around 2010. A total of 2,302 studies were published in 689 journals by our search method. Nicotine and tobacco research was the most published journal. The most prolific country was the United States, while the most influential institution was Virginia Commonwealth University. Eight of the top ten authors were from the United States. Oxidative stress, high school students, smoking cessation, delivery, behavioral economics, and exposure were the top topics.
    Conclusions: As an emerging social phenomenon, research on e-cigarettes has increased significantly over the past decade, particularly from 2015 to 2020. The top three core journals are Nicotine and Tobacco Research, the International Journal of Environmental Research, and Public Health. Eisenberg-Thomas had published numerous articles on e-cigarettes that had been co-cited in many papers. Oxidative stress, high school students, and smoking cessation are the top three areas of e-cigarette-related research, which were also important areas for further investigation.

    Bibliometric analysis of global research trends on post-stroke pneumonia: Current development status and research Frontiers.
    Xiangfei Li, Jiahui Yu, Chang Shu.
       Background: As one of the most common complications of stroke, post-stroke pneumonia significantly increases the incidence of adverse outcomes, mortality, and healthcare costs for patients with stroke. As the field of post-stroke pneumonia has gained interest in the recent years, there has been an increasing number of publications on post-stroke pneumonia research worldwide. Therefore, a more comprehensive understanding of the field is needed now. This paper is intended to analyze the research status and detect the research frontiers in this field.
    Methods: VOS viewer, CiteSpace, and the online scientometric platform (https://bibliometric.com/) were the main visualization tools used in this paper. They were used to perform citation analysis of countries/institutions, co-citation analysis of authors/journals/references, co-authorship analysis of authors, co-occurrence analysis of keywords, and citation bursts analysis of references.
    Results: The number of publications in this field has increased rapidly since 2010 and is expected to continue to increase in the next few years. The countries contributing most to post-stroke pneumonia research were the USA, China, and Germany. The most productive institution was Harvard University, followed by Humboldt University of Berlin, Charité Universitätsmedizin Berlin, and Free University of Berlin from Germany. Meanwhile, the German authors Meisel A, Meisel C, and Dirnagl U, who have contributed significantly to this field, were all associated with these three German institutions. The high-quality and high output journal was STROKE. In the coming years, the hot topic keywords "risk & risk-factors," "outcome & impact," "management & guidelines," and "predictors" will gain more attention in this field. Finally, hot keywords were grouped into four clusters in this paper: cluster 1 (risk-factors studies of post-stroke pneumonia), cluster 2 (clinically relevant studies of post-stroke pneumonia), cluster 3 (mechanism studies of post-stroke pneumonia), and cluster 4 (care studies of post-stroke pneumonia).
    Conclusion: This study shows the knowledge structure and evolution of the field of post-stroke pneumonia research and predicts research trends through visualization analysis. The future trend of post-stroke pneumonia research will gradually shift from clinical and mechanistic studies to treatment and prevention studies.

    A bibliometric analysis of DNA methylation in cardiovascular diseases from 2001 to 2021.
    Yan Zhang, Zijun Jia, Qingbing Zhou, Ying Zhang, Dandan Li, Yifei Qi, Fengqin Xu.
       BACKGROUND: DNA methylation is a dynamically reversible form of epigenetics. Dynamic regulation plays an important role in cardiovascular diseases (CVDs). However, there have been few bibliometric studies in this field. We aimed to visualize the research results and hotspots of DNA methylation in CVDs using a bibliometric analysis to provide a scientific direction for future research.
    METHODS: Publications related to DNA methylation in CVDs from January 1, 2001, to September 15, 2021, were searched and confirmed from the Web of Science Core Collection. CiteSpace 5.7 and VOSviewer 1.6.15 were used for bibliometric and knowledge-map analyses.
    RESULTS: A total of 2617 publications were included in 912 academic journals by 15,584 authors from 963 institutions from 85 countries/regions. Among them, the United States of America, China, and England were the top 3 countries contributing to the field of DNA methylation. Harvard University, Columbia University, and University of Cambridge were the top 3 contributing institutions in terms of publications and were closely linked. PLoS One was the most published and co-cited journal. Baccarelli Andrea A published the most content, while Barker DJP had the highest frequency of co-citations. The keyword cluster focused on the mechanism, methyl-containing substance, exposure/risk factor, and biomarker. In terms of research hotspots, references with strong bursts, which are still ongoing, recently included "epigenetic clock" (2017-2021), "obesity, smoking, aging, and DNA methylation" (2017-2021), and "biomarker and epigenome-wide association study" (2019-2021).
    CONCLUSIONS: We used bibliometric and visual methods to identify research hotspots and trends in DNA methylation in CVDs. Epigenetic clocks, biomarkers, environmental exposure, and lifestyle may become the focus and frontier of future research.

    Bibliometric-Based Evaluation of the Neuromarketing Research Trend: 2010-2021.
    Zeren Zhu, Yuanqing Jin, Yushun Su, Kan Jia, Chien-Liang Lin, Xiaoxin Liu.
      Neuromarketing has become a new and important topic in the field of marketing in recent years. Consumer behavior research has received increasing attention. In the past decade, the importance of marketing has also been recognized in many fields such as consumer behavior, advertising, information systems, and e-commerce. Neuromarketing uses neurological methods to determine the driving forces behind consumers' choices. Various neuroscience tools, such as eye movements, have been adopted to help reveal how consumers react to particular advertisements or objects. This information can be used as the basis for new advertising campaigns and brand promotions. To effectively explore the research trends in this field, we must understand the current situation of neuromarketing. A systematic bibliometric analysis can solve this problem by providing publishing trends and information on various topics. In this study, journals that focused on neuromarketing in the field of marketing between 2010 and 2021 were analyzed. These journals were core journals rated by the Association of Business Schools with three or more stars. According to the data analysis results, neuromarketing has 15 main journals with relevant papers. Based on the data collected by the Web of Science (WOS), this study mainly collected 119 references and analyzed the most productive countries, universities, authors, journals, and prolific publications in the field of neuromarketing via Citespace. Through the analysis of knowledge maps, this study explored the mapping of co-citation, bibliographic coupling (BC), and co-occurrence (CC). Moreover, the strongest citation bursts were used to study popular research at different time stages and analyze the research trends of neuromarketing research methods and tools. This study provides an overview of the trends and paths in neuromarketing, which can help researchers understand global trends and future research directions.

    A grey zone for bibliometrics: publications indexed in Web of Science as anonymous.
    Amrollah Shamsi, Rafaela Carolina Silva, Ting Wang, N Vasantha Raju, Karen Santos-d'Amorim.
      Publications without authorship information have been indexed as anonymous in the Web of Science database over the years. However, discussions on this subject have not been sufficiently addressed in the scholarly literature. Since bibliometrics studies are widely used for bibliometricians, scientific disciplines, science policy, and management, missing significant data as authorship metadata characterizes a gray zone that directly impacts these three components, and by extension, for bibliometrics and scientometrics. With a data collection performed at Web of Science Core Collection (WoSCC), 1,420,842 documents under "anonymous" authorship from 1900 to 2021 were retrieved, which accounted for 1.5% of the total documents indexed in the WoSCC. The publication data such as yearly growth of research publications, document type, language, productive research areas, and other bibliometric indicators were analyzed. The findings showed that in absolute numbers, a considerable growth of anonymous publications between 1996 and 2009, and there was a downward trend after that. However, this increase has not been proportional to the growth in the total number of publications indexed in the WoSCC. Articles, editorial materials, and news items were the top three document types among the WoSCC-indexed publications as anonymous. This study also finds two main scenarios of indexing publications as anonymous. The first is associated with the historical context of scholarly communication and practices that persist. The second is characterized by indexing persistent problems. This study suggests minimizing the error in databases, enabling an error-free indexing system and accurate bibliometrics studies.

    Research Trends and Geographical Contribution in the Field of Perinatal Mental Health: A Bibliometric Analysis from 1900 to 2020.
    Usman Ali, Ahmed Waqas, Muhammad Ayub.
       Objective: The object of this research is to identify growth and geographical distribution of research in the field of perinatal mental health and key research areas.
    Materials and Methods: We performed a bibliometric analysis on research documents on perinatal mental health from 1900 to 2020. Web of Science was used to download bibliometric data. Search strategy used generic index terms with specific free text searches using "AND" as Boolean function. For example, psycho AND perinatal. Microsoft Excel was used to identify research growth, geographical and research institutes contribution to research in the field. Citation analysis was done using VOSviewer.
    Results: A total of 11,081 articles were extracted. The most cited research was by Cox et al., which introduced Edinburgh Postnatal Depression Scale. There was exponential increase in the research documents from 1990 to 2020. However, most of the research was contributed by the global north. Among emerging countries, India, South Africa, and Brazil did not contribute in the perinatal research. Postnatal depression and its risk factors were most studied themes. Paternal perinatal mental health and impact on mental health of children were understudied themes.
    Conclusion: Perinatal mental health research outpaced growth in biomedical research in the past 30 years. The work of leading researcher in the field was initially inspired by his experience in Uganda encountering postnatal depression. However, even after half a century, there is still less contribution from developing countries. This analysis highlights research and possibly access to services inequities in developing countries.

    Knowledge mapping and research hotspots of immunotherapy in renal cell carcinoma: A text-mining study from 2002 to 2021.
    Kun Liu, Seling Zhao, Jian Li, Yikun Zheng, Haiyang Wu, Jianqiu Kong, Zefeng Shen.
       Background: Renal cell carcinoma (RCC) is one of the most lethal urological malignancies, and because early-stage RCC is asymptomatic, many patients present metastatic diseases at first diagnosis. With the development of immunotherapy, the treatment of RCC has entered a new stage and has made a series of progress. This study mainly outlines the knowledge map and detects the potential research hotspots by using bibliometric analysis.
    Methods: Publications concerning RCC immunotherapy from 2002 to 2021 in the Web of Science Core Collection were collected. Visualization and statistical analysis were mainly performed by freeware tools VOSviewer, CiteSpace, R software, and Microsoft Office Excel 2019.
    Results: A total of 3,432 papers were collected in this study, and the annual number of papers and citations showed a steady growth trend. The United States is the leading country with the most high-quality publications and is also the country with the most international cooperation. The University of Texas MD Anderson Cancer Center is the most productive organization. The Journal of Clinical Oncology is the highest co-cited journal, and Brian I. Rini is both the most prolific author and the author with the largest centrality. The current research hotspots may be focused on "immune checkpoint inhibitors (ICIs)," "PD-1," and "mammalian target of rapamycin."
    Conclusion: Immunotherapy has a bright future in the field of RCC treatment, among which ICIs are one of the most important research hotspots. The main future research directions of ICI-based immunotherapy may focus on combination therapy, ICI monotherapy, and the development of new predictive biomarkers.

    Tong Chen, Yue Yu, Fan Jia, Peijie Luan, Xinmin Liu.
       Background: Polycystic ovary syndrome (PCOS) is a common clinical disease often associated with insulin resistance (IR). The interaction between PCOS and IR will promote the progress of PCOS and the risk of related complications, harm women's physical and mental health, and increase the social and economic burden.
    Materials and Methods: PCOS IR-related works of literature were retrieved through the Web of Science Core Collection (WoSCC) Database and imported into VOSviewer and CiteSpace, respectively, in plain text format to conduct the literature visualization analysis of authors, countries, institutions, highly cited works of literature, and keywords, aiming to reveal the hot spots and trends of PCOS IR fields.
    Results: A total of 7,244 articles were retrieved from 1900 to 2022. Among them, the United States has made the largest contribution. Diamanti-Kandarakis E was the author with the most publications, and the University of Athens was the institution with most publications. Keyword analysis showed that PCOS interacts with IR mainly through sex-hormone binding globulin, luteinizing hormone, insulin-like growth factor, oxidative stress, and other mechanisms. In addition, the complications of PCOS complicated with IR are also the focus of researchers' attention.
    Conclusions: Through bibliometric analysis, this paper obtains the research hotspot and trend of PCOS IR fields, which can provide a reference for subsequent research.

       BACKGROUND: Vietnam's 2045 development plan requires thorough reforms in science and technology, which underlines the role of research-oriented universities in generating and transforming knowledge. Understanding the current research performance and productivity in Vietnam is important for exploiting future agendas.
    OBJECTIVE: This study aims to explore the growth patterns and collaborations in the scientific publications of Vietnam.
    METHODS: Data on documents in the Web of Science Core Collection database were searched and extracted to examine the research performance in Vietnam. Publication growth patterns in both quantity and quality were examined. The evolution of research disciplines and collaboration networks were also analyzed. Trends in the growth in the number of publications, citations, and average citations per publication between 1966 and 2020 were presented. Temporal tendencies of the 10 most productive research areas in each period were illustrated. VOSviewer software was used to analyze the discipline network, country network, and institution networks. The trends and the geographical distribution of the number of publications and citations were analyzed.
    RESULTS: A total of 62,752 documents in 8354 different sources from 1966 to 2020 were retrieved. A substantial growth was observed in the Vietnamese scientific output during this period, which was mainly research with international collaboration. Natural sciences such as mathematics, materials science, and physics were the top 3 most productive research fields during 1966-2020 in Vietnam, followed by experimental research fields such as multidisciplinary sciences, plant sciences, public, environmental, and occupational health. In 1966-2020, there was the emergence of multidisciplinary research-oriented universities in both public and private sectors along with a significant increase in the number of interdisciplinary and multidisciplinary publications. Although the scientific quality has improved, these publications are still of mostly medium quality as they are concentrated in middle-ranking journals.
    CONCLUSIONS: Our study highlights the notable growth in research performance in terms of both quality and quantity in Vietnam from 1966 to 2020. Building multidisciplinary and interdisciplinary research agenda, developing networks of local and international researchers for addressing specific local issues, improving the participation of private sectors, and developing science and technology mechanisms are critical for boosting the research productivity in Vietnam.

    Pan Chen, Xiao-Hong Li, Zhaohui Su, Yi-Lang Tang, Yi Ma, Chee H Ng, Yu-Tao Xiang.
       Objectives: The growing rate of retraction of scientific publications has attracted much attention within the academic community, but there is little knowledge about the nature of such retractions in schizophrenia-related research. This study aimed to analyze the characteristics of retractions of schizophrenia-related publications.
    Materials and methods: The Web of Science was searched for eligible studies. A bibliometric analysis was conducted to describe the characteristics of the retractions using R software and Excel 2019. Content analysis was conducted to examine the essential components of retraction notices.
    Results: A total of 36 retracted publications with 415 citations were identified from 1997 to 2021, of which, 83.3% occurred in the last decade. The overall retraction rate was 0.19%, with most of them (29; 80.56%) from the United Kingdom. The retractions were published in 33 journals, and the 2020 IFs ranged between 0.17 and 49.96 (Median = 3.93). The retractions involved 21 research areas, particularly in Psychiatry (19; 52.78%), Neurosciences and Neurology (10; 27.78%), and Psychology (7; 19.44%). Data issues (17; 42.22%), administrative errors of the publishers (5; 13.89%), and study design (4; 11.11%) were the top three reasons for retractions.
    Conclusion: This study provides an insight into retractions of schizophrenia-related publications. Institutional governance should be further strengthened to improve the scrutiny of publications, prevent continuing citations, and erroneous propagation after retraction.

    Cardiac Involvement in COVID-19: A Global Bibliometric and Visualized Analysis.
    Si-Chi Xu, Xin-Yue Zhao, Hai-Ping Xing, Wei Wu, Shu-Yang Zhang.
       Objective: Coronavirus disease 2019 (COVID-19), which was caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), had already resulted in widespread epidemics worldwide and millions of people's deaths since its outbreak in 2019. COVID-19 had also been demonstrated to affect people's cardiac function. However, the specific mechanism and influence of this damage were not clear yet. The purpose of the present study was to provide a bibliometric analysis of the current studies related to cardiac involvement after SARS-CoV-2 infection.
    Methods: A bibliometric literature search was performed on the web of science. The number and type of publications, countries, institutional sources, journals, and citation patterns were analyzed. In addition, qualitative and quantitative evaluations were carried out to visualize the scientific achievements in this field by using the VOSviewer software.
    Results: Web of science had recorded 2,24,097 documents on COVID-19 at the time of data collection (May 12, 2022). A total of 2,025 documents related to cardiac involvement were recorded at last. The countries with the most published articles were the United States of America (USA) (n =747, 36.9%), Italy (n =324, 16%), and England (n =213, 10.5%). Although the countries and institutions that published the most articles were mainly from the USA, the top three authors were from Germany, England, and Poland. Frontiers in Cardiovascular Medicine was the journal with the most studies (65 3.2%), followed by ESC Heart Failure (59 2.9%) and Journal of Clinical Medicine (56 2.8%). We identified 13,739 authors, among which Karin Klingel and Amer Harky had the most articles, and Shaobo Shi was co-cited most often. There existed some cooperation between different authors, but the scope was limited. Myocarditis and heart failure (HF) were the main research hotspots of COVID-19 on cardiac dysfunction and may be crucial to the prognosis of patients.
    Conclusions: It was the first bibliometric analysis of publications related to COVID-19-associated cardiac disorder. This study provided academics and researchers with useful information on the most influential articles of COVID-19 and cardiac dysfunction. Cooperation between countries and institutions must be strengthened on myocarditis and HF during COVID-19 pandemic.

    Ali Shabestani Monfared, Ali Bijani, Khadijeh Tahmasbi, Mousa Yaminfirooz.
       Background: Considering the importance of internal medicine and the lack of sufficient scientometric data on the research status of the field in Iran, the study aimed at investigating the state of scientific output in the country compared to the countries in the world.
    Methods: This applied research used a scientometric approach. The related MeSH-driven terms in "internal medicine" were selected as search phrases and searched in the SCImago database. SPSS and Excel software packages were used for statistical analysis. Geographical mapping was done with Google Maps for depicting country geographical distribution.
    Results: Out of all 4,972,258 papers published by 230 countries worldwide in the field, about 60% belonged to the USA and Western European countries. These countries were at top of citation and self-citation counts as well as the h-index indicator. The citations per paper indicator were 27.1 and about 25.1% of total citations were self-citations. A significant positive correlation was found between the number of papers, citation count, and self-citation rate, and h-index in the field (p<0.001).
    Conclusion: The research status of internal medicine in developed regions and countries was quantitatively and qualitatively better than that of developing countries, including Iran.

    Vagal Nerve Stimulation: A Bibliometric Analysis of Current Research Trends.
    Margaret H Downes, Roshini Kalagara, Susmita Chennareddy, Vikram Vasan, Emma Reford, Braxton R Schuldt, Ian Odland, Jenna Tosto-Mancuso, David Putrino, Fedor Panov, Christopher P Kellner.
       BACKGROUND: Vagal nerve stimulation (VNS) has become established as an effective tool for the management of various neurologic disorders. Consequently, a growing number of VNS studies have been published over the past four decades. This study presents a bibliometric analysis investigating the current trends in VNS literature.
    MATERIALS AND METHODS: Using the Web of Science collection data base, a search was performed to identify literature that discussed applications of VNS from 2000 to 2021. Analysis and visualization of the included literature were completed with VOSviewer.
    RESULTS: A total of 2895 publications were identified. The number of articles published in this area has increased over the past two decades, with the most citations (7098) occurring in 2021 and the most publications (270) in 2020. The h-index, i-10, and i-100 were 97, 994, and 91, respectively, with 17.0 citations per publication on average. The highest-producing country and institution of VNS literature were the United States and the University of Texas, respectively. The most productive journal was Epilepsia. Epilepsy was the predominant focus of VNS research, with the keyword "epilepsy" having the greatest total link strength (749) in the keyword analysis. The keyword analysis also revealed two major avenues of VNS research: 1) the mechanisms by which VNS modulates neural circuitry, and 2) therapeutic applications of VNS in a variety of diseases beyond neurology. It also showed a significant prevalence of noninvasive VNS research. Although epilepsy research appears more linked to implanted VNS, headache and depression specialists were more closely associated with noninvasive VNS.
    CONCLUSION: VNS may serve as a promising intervention for rehabilitation beyond neurologic applications, with an expanding base of literature over the past two decades. Although epilepsy researchers have produced most current literature, other fields have begun to explore VNS as a potential treatment, likely owing to the rise of noninvasive forms of VNS.

    Sa'ed H Zyoud, Muna Shakhshir, Amani S Abushanab, Samah W Al-Jabi, Amer Koni, Moyad Shahwan, Ammar Abdulrahman Jairoun, Adham Abu Taha.
       BACKGROUND: Nutrition is a significant modifiable element that influences the composition of the gastrointestinal microbiota, implying the possibility of therapeutic diet methods that manipulate the composition and diversity of the microbial.
    AIM: To overview research papers on nutrition and gut microbiota and determines the hotspots in this field at the global level.
    METHODS: Scopus and Reference Citation Analysis were used to construct a bibliometric technique. It was decided to create bibliometric indicators and mapping as in most previous studies. 2012 through 2021 served as the study's timeframe.
    RESULTS: A total of 5378 documents from the Scopus database were selected for analysis. Of all retrieved studies, 78.52% were research papers (n = 4223), followed by reviews (n = 820; 15.25%). China ranked first with a total number of articles of 1634 (30.38%), followed by the United States in second place with a total number of articles of 1307 (24.3%). In the last decade, emerging hotspots for gut microbiota and nutrition research included "gut microbiota metabolism and interaction with dietary components", "connection between the gut microbiota and weight gain", and "the influence of high-fat diet and gut microbiota on metabolic disorders".
    CONCLUSION: This is the first thorough bibliometric analysis of nutrition and gut microbiota publications conducted on a global level. Investigation of the association between nutrition/diet and the gut microbiota is still in its infancy and will be expanded in the future. However, according to recent trends, the "effect of gut microbiota and high-fat diet on metabolic disorders" will be an increasing concern in the future.

    Emerging trends and knowledge domain of research on urban green open spaces and wellbeing: A scientometric review.
    Akansha Shrivastava, Surabhi Mehrotra.
      Green Open Spaces (GOS) and its linkages to human health and wellbeing have received growing attention in the field of urban planning. In spite of increase in number of studies in this field, there is lack of scientometric perspective pertaining to this research domain. The purpose of the study is to map the research status and key research directions in the interdisciplinary domain: Green open spaces, public health and urban planning, using Citespace. Scientometric analysis (co-author, co-citation, co-word and cluster analysis) is conducted for 451 peer reviewed publications, primarily published in last two decades (2000-2021) in the web of science database. The study assessed influential authors, journals and documents to identify the intellectual structure and network of co-authorship and countries to understand research collaborations of this domain. As a result of this review, five emerging research trends in this domain are identified - Emerging data sources, Study areas at various spatial scales, Type of study, Assessment of urban GOS benefits and Urban planning contribution in the research area. In addition, critical review of these trends is conducted to understand corresponding challenges and opportunities. The critical analysis highlighted the need of generating evidence base appropriate for assessing GOS use and user perception, especially in developing nations capturing socio-demographic diversity. The use of Citespace for scientometric analysis facilitated the systematic understanding of this research area by visualizing and analyzing various patterns and trends. This study provides an intensive understanding of present research status and emerging trends of this research domain. Findings in this study are envisioned to provide practitioners, decision makers and researchers with promising future research directions.

    Retracted Publications in Medical Imaging Literature: an Analysis Using the Retraction Watch Database.
    Robert M Kwee, Thomas C Kwee.
       RATIONALE AND OBJECTIVE: It is currently unknown how many publications in the medical imaging literature are retracted and for which reasons. The purpose of this study was to perform an updated analysis on retracted medical imaging publications using the Retraction Watch Database.
    MATERIALS AND METHODS: The Retraction Watch Database was searched for all retracted publications in the subject category "Radiology/Imaging" (no beginning date limit, search update until April 27, 2022). Reasons for retraction were extracted using standardized coding taxonomy. The number of citations per retracted publication was determined. Spearman's rho was used for statistical analysis.
    RESULTS: 192 retractions, originally published between 1984 and 2021, were included. Most retractions originated from China (31.3%), the United States (12.5%), Japan (7.3%), and South Korea (6.3%). The number of retractions increased over the years, especially since 2000 (Spearman's rho=0.764, p <0.001). Delay between original publication and retraction ranged from 0 days to 14 years and 3 months (median of 11 months). Most common reasons for retraction were duplication of article (7.1%), plagiarism of article (6.8%), concerns/issues about data (5.4%), investigation by company/institution (4.5%), and forged authorship (4.0%). Scientific misconduct was deemed present in 107 of 192 retracted articles (55.7%). Retracted articles (of which 138 were listed in Web of Science) received a median of 2 citations (range 0-148, IQR 5).
    CONCLUSION: The number of retracted medical imaging publications continues to increase over time, which could indicate that more compromised research has either been published or discovered. Scientific misconduct was the main cause for retraction.

    Trends in Artificial Intelligence in Nursing: Impacts on Nursing Management.
    Ching-Yi Chang, Hsiu-Ju Jen, Wen-Song Su.
       OBJECTIVE: Investigate the academic use of artificial intelligence in nursing.
    BACKGROUND: Bibliometric analysis combined with the VOSviewer software quantification method has been utilized for literature analysis. In recent years, this approach has attracted the interest of scholars in various research fields. Thus far, there is no publication using bibliometric analysis combined with the VOSviewer software to analyze the applications of artificial intelligence in nursing.
    METHOD: A bibliometric analysis methodology was used to search for relevant articles published between 1984 and March 2022. Six databases, Embase, Scopus, PubMed, CINAHL, WoS, and MEDLINE, were included to identify relevant studies, and data such as the year of publication, journals, country, institutional source, field, and keywords were analyzed.
    RESULTS: Most relevant articles were published from institutions in the United States of America. The League of European Research Universities has published most research studies that use artificial intelligence and nursing. Scholars have mainly focused on nursing, medical informatics, computer science AI, health care sciences services, and physics particles fields. Commonly used keywords were machine learning, care, artificial intelligence, natural language processing, prediction, and nurse.
    CONCLUSION: Research articles were mainly published in Nurse Education Today. Research topics such as artificial intelligence-assisted medical recording and medical decision-making were also identified. According to this study, artificial intelligence in nursing has the potential to attract more attention from researchers and nursing managers. Additional high-quality research beyond the scope of medical education, as well as on cross-domain collaboration, is warranted to explore the acceptability and effective implementation of artificial intelligence technologies.
    IMPLICATIONS FOR NURSING MANAGEMENT: This study provides scholars and nursing managers with structured information regarding the use of artificial intelligence in nursing based on scientific and technological developments across different fields and institutions. The application of artificial intelligence can improve nursing management, nursing quality, safety management, and team communication, as well as encourage future international collaboration.

    A bibliometric study on the publication errors in emergency medicine journals from 2000 to 2020.
    Sevilay Vural, Hasan Burak Kaya, Figen Coskun.
       BACKGROUND: The literature on scientific publication errors in medical research is limited, and no studies on emergency medicine publications have been conducted yet. This study aimed to investigate the characteristics of the publication errors in emergency medicine literature.
    METHODS: This bibliometric study reviewed intervened publication errors in the manuscripts of seven high-impact emergency medicine journals from 2000 to 2020, covering twenty years, and evaluated the corrections in the forms of an erratum, corrigendum, addendum, and retracted papers. The detected publication error rate and the trend, error severity, and error types were calculated.
    RESULTS: We detected 257 intervened scientific papers consisting of 251 corrections due to one or more publication errors and six retractions. Authors were the primary source of the errors (93.2%). Most of the errors were in the author attribution section (40.5%). The published errors of 7.2% had an impact on the paper's conclusion. Simple typographic errors were the most common error type (62.5%). The corrected publication error rate was 1.3%, with a steady trend over the twenty years.
    CONCLUSIONS: Publications errors are inevitable, but it is possible to minimize them. The number of corrections in emergency medicine literature is at a low rate and show many similarities with the previous literature.

    A bibliometric analysis of neuroimaging biomarkers in Parkinson disease based on Web of Science.
    Xiao-Ling Li, Rui-Xue Gao, Qinhong Zhang, Ang Li, Li-Na Cai, Wei-Wei Zhao, Sheng-Lan Gao, Yang Wang, Jinhuan Yue.
       BACKGROUND: This study aimed to analyze and summarize the research hotspots and trends in neuroimaging biomarkers (NMBM) in Parkinson disease (PD) based on the Web of Science core collection database and provide new references for future studies.
    METHODS: Literature regarding NMBM in PD from 1998 to 2022 was analyzed using the Web of Science core collection database. We utilized CiteSpace software (6.1R2) for bibliometric analyses of countries/institutions/authors, keywords, keyword bursts, references, and their clusters.
    RESULTS: A total of 339 studies were identified with a continually increasing annual trend. The most productive country and collaboration was the United States. The top research hotspot is PD cognitive disorder. NMBM and artificial intelligence medical imaging have been applied in the clinical diagnosis, differential diagnosis, treatment, and prognosis of PD. The trends in this field include research on T1 weighted structure magnetic resonance imaging in accordance with voxel-based morphometry, PD cognitive disorder, and neuroimaging features of Lewy body dementia and Alzheimer disease.
    CONCLUSION: The development of NMBM in PD will be effectively promoted by drawing on international research hotspots and cutting-edge technologies, emphasizing international collaboration and institutional cooperation at the national level, and strengthening interdisciplinary research.

    Authorship Trends of Women in Retina: A 25-Year Analysis.
    Ankur Nahar, Raziyeh Mahmoudzadeh, Martina Rama, Rebecca R Soares, Yoshihiro Yonekawa, Sonia Mehta, Julia A Haller.
       OBJECTIVE: To examine trends in first and last authorship of women within clinical retina research over the last 25 years.
    DESIGN: Cross-sectional study.
    PARTICIPANTS: First and last authors were retrieved from original articles published between January 1st, 1995, and January 1st, 2021, in the American Journal of Ophthalmology, JAMA Ophthalmology (Archives of Ophthalmology), Ophthalmology, and Retina.
    METHODS: The MeSH major term "retina" was used in PubMed to filter publications specific to the field of retina. Publications by single authors and collaborative study groups and those classified as comments, letters, and editorials were excluded. First and last author names were obtained, and GenderAPI was used to assign sex. Names were crosschecked with the American Society of Retina Specialists (ASRS) directory for United States-based authors.
    MAIN OUTCOME MEASURES: The proportion of male and female first and last authors throughout the study period and the association between first and last authorship gender were assessed.
    RESULTS: A total of 4142 papers were included. The percentage of women in first and last authorship positions significantly increased from 23% to 37.7% and 14.2% to 24.6% over 25 years, respectively (P<0.001, P<0.001, respectively). When the last authors were women, 32.5% of the first authors were women, and when the last authors were men, 27.1% of the first authors were women (P=0.002). Based on the ASRS 2020 directory, 17% of practicing retina specialists in the United States were women in 2020. For publications in 2020, 28.2% of the first authors and 22.3% of the last authors of retina publications from the United States were women (P<0.001, P<0.001, respectively).
    CONCLUSION: While a disparity in authorship persists in ophthalmology's subspecialties, this data suggests that retina is a field where the gap is improving. Mentorship by senior female authors is associated with a higher proportion of female first authors.

    New and emerging forms of data and technologies: literature and bibliometric review.
    Petar Radanliev, David De Roure.
      With the increased digitalisation of our society, new and emerging forms of data present new values and opportunities for improved data driven multimedia services, or even new solutions for managing future global pandemics (i.e., Disease X). This article conducts a literature review and bibliometric analysis of existing research records on new and emerging forms of multimedia data. The literature review engages with qualitative search of the most prominent journal and conference publications on this topic. The bibliometric analysis engages with statistical software (i.e. R) analysis of Web of Science data records. The results are somewhat unexpected. Despite the special relationship between the US and the UK, there is not much evidence of collaboration in research on this topic. Similarly, despite the negative media publicity on the current relationship between the US and China (and the US sanctions on China), the research on this topic seems to be growing strong. However, it would be interesting to repeat this exercise after a few years and compare the results. It is possible that the effect of the current US sanctions on China has not taken its full effect yet.

    The Impact of Dedicated Research Years During Residency Upon Continued Academic Productivity of Plastic Surgeons.
    Narainsai K Reddy, Sarah A Applebaum, Arun K Gosain.
       BACKGROUND: This study explored the impact of dedicated research year(s) on long-term research productivity and career choices of plastic surgeons as academicians.
    METHODS: Scopus and Web of Science were accessed in September 2020 to collate publications and H indexes of alumni who graduated from integrated plastic surgery residency programs from 2011 to 2020. Public profiles were utilized to determine academic status. Corresponding data were grouped by residency program type (traditional programs without required research, programs with one required research year, and a single program with variable research years). Unpaired t tests and 1-way analysis of variance were conducted to compare average H indexes and publication counts of alumni from each group. χ2 tests analyzed differences in academic statuses.
    RESULTS: Alumni who completed one required research year published significantly more with a higher H index compared with those from traditional programs. Similar results were found among alumni who completed 2 research years compared with 0 or 1 year within a single program. Residents who completed one required research year were more likely to hold dual academic and nonacademic positions after graduation compared with their traditional counterparts. However, there was no statistical difference in academic status observed for surgeons who graduated from the program with variable research years.
    CONCLUSIONS: Participating in research year(s) during residency is predictive of ongoing academic productivity of surgeons within the first 10 years of completion of residency. This becomes important for training craniofacial surgeons, the majority of whom practice in academic settings.

    The influence of Covid-19 on publications in economics: bibliometric evidence from five working paper series.
    Constantin Bürgi, Klaus Wohlrabe.
      We compare Covid-related working papers in economics to non-Covid-related working papers in four dimensions. Based on five well-known working papers series and data from the RePEc website, we find that Covid papers mainly cover topics in macroeconomics and health, they are written by larger teams than non-Covid papers, are more often downloaded and they receive more citations relative to non-Covid papers.

    A Bibliometric Analysis for Global Trends and Full View of the Autophagy in Ischemic Stroke from 2006 to 2022.
    Lijuan Song, Yige Wu, Shuwen Yuan, Kexin Liu, Qing Wang, Dong Ma, Cungen Ma.
      Autophagy plays a key role in ischemic stroke, but its mechanism remains to be elucidated. In order to explore the effect of autophagy on ischemic stroke, bibliometric analysis and view tools are used to identify the directions of the global research trends and construct full view of the autophagy in ischemic stroke from 2006 to 2022. The research hotspots of autophagy related to ischemic stroke are visually analyzed and generated various visual maps to display publications, authors, sources, countries, organizations, and keywords. By bibliometric analysis, it can be seen that the investigations of autophagy in ischemic stroke is focused on both brain injury and neuroprotection. The impact of a variety of inflammatory factors and signaling pathways on autophagy following an ischemic stroke is also studied. Autophagy plays an important role in all phases of ischemic stroke. It is of great significance to guide the development of treatment plans for ischemic stroke.

    Complementary and Alternative Medicine for Long COVID: Scoping Review and Bibliometric Analysis.
    Tae-Hun Kim, Sae-Rom Jeon, Jung Won Kang, Sunoh Kwon.
      Prolonged symptoms after the clearance of acute coronavirus disease 2019 (COVID-19) infection, termed long COVID, are an emerging threat to the post-COVID-19 era. Complementary and alternative medicine (CAM) interventions may play a significant role in the management of long COVID. The present study aimed to identify published studies on the use of CAM interventions for long COVID and provide an overview of the research status using bibliometric analysis. The present scoping review searched MEDLINE, Embase, and Cochrane Library from inception until November 2021 and identified published studies on CAM interventions for long COVID. A narrative analysis of the study types and effectiveness and safety of the CAM interventions are presented and a bibliometric analysis of citation information and references of the included publications were analyzed using the Bibliometrix package for R. An electronic database search identified 16 publications (2 clinical studies and 14 study protocols of systematic reviews or clinical studies) that were included in the present study. Dyspnea or pulmonary dysfunction, quality of life, olfactory dysfunction, and psychological symptoms after COVID-19 infection were assessed in the included publications. The two clinical studies suggested that Chinese herbal medications were effective in relieving symptoms of pulmonary dysfunction. Bibliometric analysis revealed the current trend of research publication in this area was driven by study protocols written by Chinese, Korean, and Indian authors. Thus, the present scoping review and bibliometric analysis revealed that there are few studies published about the use of CAM for long COVID and long-term management for COVID-19 survivors. Original studies on CAM interventions, including randomized controlled trials and systematic reviews, are required to actively support evidence for their use in the management of long COVID. PROSPERO registration: this trial is registered with CRD42021281526.

    Demographics and Academic Productivity of Cardiothoracic Imaging Fellowship Program Directors in the United States: A Cross-Sectional Review.
    Zachary D Zippi, Benjamin I Schachner, Nathan Vanderveer-Harris, Nicholas Jaeger, Michael Zalkind, Justin Stowell, Patricia J Mergo.
      Background In this study, we aimed to assess current demographics, measures of academic productivity, and other objective leadership characteristics among United States cardiothoracic imaging fellowship directors (FDs). Methodology A survey was sent to active members listed in the Society of Thoracic Radiology Cardiothoracic Imaging Fellowship Directory. Demographic, post-graduate training, and scholarly activity data were collected, including, but not limited to, age, sex, residency and fellowship training institutions, time since training completion until FD, length of time as FD, and Hirsch-index (h-index) to measure research activity. Results We identified 53 FDs from 50 cardiothoracic imaging fellowship programs. Of these, 31 (58.5%) were male and 22 (41.5%) were female with an average age of 48.5 years (standard deviation (SD) = 8.4, range = 35-67). There was no statistically significant difference between the mean age of male and female FDs (47.5 vs 50.2 years, p = 0.2811). The mean age of appointment to the FD role was 41.8 years. On average, FDs graduated from residency in 2005 and 2007 for fellowships. Most attended allopathic medical schools (52/53, 98.1%). The average Scopus h-index was 15.7 (SD = 17.4). Gender-wise comparison of mean h-indices revealed 16.2 for males and 15 for females, with no statistically significant difference between the two groups (p = 0.81). Ten (18.9%) FDs and 20 (37.7%) FDs were at the same location they completed residency and fellowship training, respectively. Conclusions This cross-sectional study shows the present demographics within the cardiothoracic radiology FD position. This field of radiology is observed to have FDs with research productivity that is comparable with other medical specialties. Some radiology residency and fellowship programs were shown to produce more FDs than others; however, we were not able to identify causality. Program directors appear to be selected from a familiar pool of applicants, and ultimately FDs are being replaced by individuals with similar distinctions. Overall, this research into cardiothoracic radiology FDs demographics and research productivity can add to the current body of literature on FDs in various medical specialties. It is important to continue to reflect on medical leadership as the field continues to advance.

    NLP4NLP+5: The Deep (R)evolution in Speech and Language Processing.
    Joseph Mariani, Gil Francopoulo, Patrick Paroubek, Frédéric Vernier.
      This paper aims at analyzing the changes in the fields of speech and natural language processing over the recent past 5 years (2016-2020). It is in continuation of a series of two papers that we published in 2019 on the analysis of the NLP4NLP corpus, which contained articles published in 34 major conferences and journals in the field of speech and natural language processing, over a period of 50 years (1965-2015), and analyzed with the methods developed in the field of NLP, hence its name. The extended NLP4NLP+5 corpus now covers 55 years, comprising close to 90,000 documents [+30% compared with NLP4NLP: as many articles have been published in the single year 2020 than over the first 25 years (1965-1989)], 67,000 authors (+40%), 590,000 references (+80%), and approximately 380 million words (+40%). These analyses are conducted globally or comparatively among sources and also with the general scientific literature, with a focus on the past 5 years. It concludes in identifying profound changes in research topics as well as in the emergence of a new generation of authors and the appearance of new publications around artificial intelligence, neural networks, machine learning, and word embedding.

    Identifying the knowledge structure of electromagnetic fields and health research: Text network analysis and topic modeling.
    GyeongAe Seomun, Suyeon Ban, Jinkyung Park.
       BACKGROUND: With technological and scientific advancement, people are being increasingly exposed to electromagnetic fields, particularly from portable devices such as mobile phones. However, there is currently no consensus regarding the health effects of electromagnetic field exposure, despite the large amount of research conducted on this topic. This study aimed to understand the knowledge structure and trend of electromagnetic field and health research through text network analysis and topic modeling.
    METHODS: PubMed, Embase, and Cochrane were searched, and 3,880 articles published before June 2021 were identified. We explored the main keywords and research topics regarding electromagnetic fields and human health by constructing a network of keywords. A social network analysis program was used to analyze the data, visualize the network, and perform topic modeling.
    RESULTS: Four keywords, "exposure," "effect," "cell," and "cancer," were highly correlated to other keywords and formed each colony in the knowledge structure of research on electromagnetic fields and health. Five topics were derived from topic modeling: cell research, research on the adaption of MRI, health effects of mobile phones, pain therapy, and exposure measurement. Cell research has been continuously performed, and many studies have been conducted on the health effects of mobile phones since 2000.
    CONCLUSIONS: These findings will assist in gaining insights into and understanding changes in research on the health effects of electromagnetic fields, and suggest important areas and directions for future research.

    Digital artifacts reveal development and diffusion of climate research.
    Bia Carneiro, Giuliano Resce, Tek B Sapkota.
      Research for development organizations generate tremendous amount of accessible knowledge, but given their scale, time and resource constraints, the impact of outputs is not systematically analyzed. This is because traditional bibliometric analyses present limitations to synthesize accumulated knowledge and retrofitting indicators to historical outputs. To address these shortcomings, this study proposes an integrated, web-based approach to systematically analyze the production and diffusion of knowledge from large-scale research programs, using climate research of the International Maize and Wheat Improvement Center (CIMMYT) as a case study. Our analytical framework employs text mining, social network analysis and hyperlink analysis to an unstructured mass of publicly available digital artifacts such as institutional repositories, citation databases, and social media to uncover narratives, dynamics, and relationships. Findings show CIMMYT's climate research is strongly incorporated into a holistic systems approach and that the institution is actively engaged in knowledge exchanges with key actors from the scientific, development and public policy communities. The proposed analytical framework establishes an effective approach for research for development organizations to leverage existing online data sources to assess the extent of their knowledge production, dissemination, and reach.

       DISCLAIMER: In an effort to expedite the publication of articles, AJHP is posting manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time.
    PURPOSE: The University of Oklahoma College of Pharmacy (OUCOP) implemented an individualized residency research committee and skill development program to facilitate completion and publication of research projects. The purpose of this study was to evaluate the outcomes the program had on project publication rates and subsequent publications after graduation for postgraduate year 1 (PGY1) and postgraduate year 2 (PGY2) residents.
    METHODS: This study included OUCOP PGY1 and PGY2 residents from classes graduating from 2011 through 2019. Literature searches for all resident projects and subsequent publications were performed. Data collection included residency type (PGY1 vs PGY2), initial position after residency, and project type. The primary objective was to identify the publication rate of research projects. Secondary objectives included a comparison of the number of publications after residency graduation between residents who did and did not publish their residency project and analysis of factors associated with subsequent publications. Zero-inflated Poisson regression was utilized to analyze subsequent publication status controlling for other factors. Statistical analyses were performed using SAS/STAT with an a priori P value of <0.05.
    RESULTS: Eighty-two projects were completed by 73 residents. Forty-three of 82 projects were published (52.4%) by 39 of 73 residents (52.1%). After residency graduation, 54 residents (74.0%) had a subsequent publication. Factors associated with subsequent publications were initial position in an academic role and completion of additional training after residency.
    CONCLUSION: After implementation of the program, the majority of residents published their projects and had subsequent publications. Future efforts should be taken to identify opportunities to foster independence in research and scholarship for residents.

    Current state of ethical challenges reported in Saudi Arabia: a systematic review & bibliometric analysis from 2010 to 2021.
    Alexander Woodman, Khawaja Bilal Waheed, Mohammad Rasheed, Shakil Ahmad.
       BACKGROUND: Over the past few years, five domains of importance about the current state of bioethics in Saudi Arabia have shaped the perspective of most research: doctor-patient relationship, informed consent, do-not-resuscitate, organ donation, and transplantation, medical students' knowledge and attitudes about medical ethics curriculum. This systematic review aimed to systematically identify, compile, describe and discuss ethical arguments and concepts in the best-studied domains of bioethics in Saudi Arabia and to present cultural, social, educational, and humane perspectives.
    METHODS: Six databases were searched using Boolean operators (PubMed, Embase, Web of Science, Scopus, CINAHL, Google Scholar) from December 2020-June 2021. The search and report process followed the statement and flowchart of preferred reporting items for systematic reviews and meta-analyses (PRISMA).
    RESUTLS: The search resulted in 1651 articles, of which 82 studies were selected for a final review and assessment. There is a gradual increase in research, whereby a substantial increase was observed from 2017. Most of the published articles focused on 'Organ Donation & Transplantation' with 33 articles, followed by 'Doctor-Patient Relations' with 18 publications. Most of the published articles were from Central Province (33), followed by Western Province (16). The authorship pattern showed a collaborative approach among researchers. The thematic analysis of keywords analysis showed that 'Saudi Arabia,' 'attitude PHC,' 'organ donation,' 'knowledge and education,' and 'donation' have been used the most commonly.
    CONCLUSION: This systematic quantitative synthesis is expected to guide researchers, stakeholders, and policymakers about the strengths and gaps in knowledge and attitudes regarding medical ethics in Saudi Arabia, both among the general public and health professionals.

    Mapping the extent, range and nature of research activity on value-based healthcare in the 15 years following its introduction (2006-2021): a scoping review.
    Joanna R G Vijverberg, Kirsten Daniels, Gijs Steinmann, Mirjam M Garvelink, Marc B V Rouppe van der Voort, Douwe Biesma, Willem Jan W Bos, Frits van Merode, Paul van der Nat.
       OBJECTIVES: We aimed to systematically map the extent, range and nature of research activity on value-based healthcare (VBHC), and to identify research gaps.
    DESIGN: A scoping review with an additional cited reference search was conducted, guided by the Joanna Briggs Institute methodology.
    DATA SOURCES: The search was undertaken in PubMed, Embase and Web of Science.
    ELIGIBILITY CRITERIA: Eligible articles mentioned VBHC or value with reference to the work of Porter or provided a definition of VBHC or value.
    DATA EXTRACTION AND SYNTHESIS: Data were independently extracted using a data extraction form. Two independent reviewers double extracted data from 10% of the articles. Data of the remaining articles (90%) were extracted by one reviewer and checked by a second. The strategic agenda of Porter and Lee was used to categorise the included articles.
    RESULTS: The searches yielded a total of 27,931 articles, of which 1,242 were analysed. Most articles were published in North America. Most articles described an application of VBHC by measuring outcomes and costs (agenda item 2). The other agenda items were far less frequently described or implemented. Most of these articles were conceptual, meaning that nothing was actually changed or implemented.
    CONCLUSION: The number of publications increased steadily after the introduction of VBHC in 2006. Almost one-fifth of the articles could not be categorised in one of the items of the strategic agenda, which may lead to the conclusion that the current strategic agenda could be extended. In addition, a practical roadmap or guideline to implement VBHC is still lacking. Future research could fill this gap by specifically studying the effectiveness of VBHC in day-to-day clinical practice.

       OBJECTIVES: To assess the frequency of reporting of ethnicity (or 'race') and socioeconomic status (SES) indicators in high-impact journals.
    DESIGN: Targeted literature review.
    DATA SOURCES: The 10 highest ranked general medical journals using Google scholar h5 index.
    ELIGIBILITY CRITERIA: Inclusion criteria were, human research, reporting participant level data. Exclusion criteria were non-research article, animal/other non-human participant/subject or no participant characteristics reported.
    DATA EXTRACTION AND SYNTHESIS: Working backwards from 19 April 2021 in each journal, two independent reviewers selected the 10 most recent articles meeting inclusion/exclusion criteria, to create a sample of 100 articles. Data on the frequency of reporting of ethnicity (or 'race') and SES indicators were extracted and presented using descriptive statistics.
    RESULTS: Of 100 research articles included, 35 reported ethnicity and 13 SES. By contrast, 99 reported age, and 97 reported sex or gender. Among the articles not reporting ethnicity, only 3 (5%) highlighted this as a limitation, and only 6 (7%) where SES data were missing. Median number of articles reporting ethnicity per journal was 2.5/10 (range 0 to 9). Only two journals explicitly requested reporting of ethnicity (or race), and one requested SES.
    CONCLUSIONS: The majority of research published in high-impact medical journals does not include data on the ethnicity and SES of participants, and this omission is rarely acknowledged as a limitation. This situation persists despite the well-established importance of this issue and International Committee of Medical Journal Editors recommendations to include relevant demographic variables to ensure representative samples. Standardised explicit minimum standards are required.

    Gender Distribution & Rank of Authorship in Surgical Literature.
    Sruthi Selvakumar, Israel Zagales, Kevin Newsome, Jeffrey Spardy, Radleigh Santos, Dessy Boneva, Deborah M Stein, Lucy Kornblith, Tracy Bilski, Adel Elkbuli.
       BACKGROUND: Authorship of surgical literature is important for the career advancement of surgeons, and gender disparities in authorship may hinder the representation and leadership of women within academic surgery. The aim of this systematic review and meta-analysis was to evaluate the gender distribution of first, senior, and overall authorship in peer-reviewed surgical journal studies across all surgical specialties to determine if disparities exist.
    METHODS: PubMed, EMBASE, and Google Scholar databases were searched for studies investigating the gender distribution of authorship of surgical literature published before December 10th, 2021. Meta-analysis was performed and Cohen's Q test for heterogenous effects was used to determine whether random or fixed-effects models were appropriate.
    RESULTS: Fifteen studies investigating gender distribution of authorship met inclusion, which included a total of 136,627 pooled studies. The meta-analysis demonstrated the meta-proportion of first authorship for women to be 20.6% (95% CI: 13.9, 28.2), the meta-proportion of senior authorship for women to be 11.9% (95% CI: 6.6, 18.5), and the meta-proportion of overall authorship for women to be 23% (95% CI: 16.2, 30.7). In addition, the proportion of senior authorship for women was found to be significantly lower than the proportion of overall authorship for women (11.9% versus 23.0%, P = .0106).
    CONCLUSION: There is a significantly smaller proportion of women who are first, senior, and overall authors in surgical literature compared to their colleagues who are men. Sustainable and effective solutions aimed at improving the representation of women surgeons in surgical research and research leadership are necessary.

    Exploring food security as a multidimensional topic: twenty years of scientific publications and recent developments.
    Maria Stella Righettini, Elisa Bordin.
      The scientific literature dealing with food security is vast and fragmented, making it difficult to understand the state of the art and potential development of scientific research on a central theme within sustainable development. The current article, starting from some milestone publications during the 1980s and 1990s about food poverty and good nutrition programmes, sets out the quantitative and qualitative aspects of a vast scientific production that could generate future food security research. It offers an overview of the topics that characterize the theoretical and empirical dimensions of food security, maps the state of the art, and highlights trends in publications' ascending and descending themes. To this end the paper applies quantitative/qualitative methods to analyse more than 20,000 scientific articles published in Scopus between 2000 and 2020. Evidence suggests the need to find more robust links between micro studies on food safety and nutrition poverty and macro changes in food security, such as the impact of climate change on agricultural production and global food crises. However, the potential inherent in the extensive and multidisciplinary research on food safety encounters limitations, particularly the difficulty of theoretically and empirically connecting the global and regional dimensions of change (crisis) with meso (policy) and micro (individual behaviour) dimensions.

    A scientometric study on application of electrochemical sensors for detection of pesticide using graphene-based electrode modifiers.
    Yuhong Zheng, Shuduan Mao, Jiangwei Zhu, Li Fu, Majid Moghadam.
      Pesticide testing is an important topic in environmental protection and food safety. The development of green, accurate and reliable pesticide residue detection methods is an important technical support for implementing of agricultural quality supervision. Electrochemical sensors are a very promising analytical method for pesticide detection due to their high sensitivity, speed, low cost and portability. Performance enhancement of electrochemical sensors is often accompanied by research advances in materials science. Among them, carbon material is a very important electrode material for the fabrication of electrochemical sensors. The discovery of graphene makes it the most promising candidate among carbon materials for sensor performance enhancement. The topic of this review is the use of graphene-modified electrochemical sensors for pesticide detection in the last decade. Traditional literature summaries and bibliometric analyses were used for an in-depth analysis of this topic. In addition to the introduction of different sensor types and performance comparisons, this review also parses the authors' country, keywords and publication frequency. The related research experienced rapid growth several years ago and has now reached a relatively stable stage. We also discuss the perspectives on this topic.

    Shilpa Verma, Rajesh Bhatia, Sandeep Harit, Sanjay Batish.
      The necessity for scholarly knowledge mining and management has grown significantly as academic literature and its linkages to authors produce enormously. Information extraction, ontology matching, and accessing academic components with relations have become more critical than ever. Therefore, with the advancement of scientific literature, scholarly knowledge graphs have become critical to various applications where semantics can impart meanings to concepts. The objective of study is to report a literature review regarding knowledge graph construction, refinement and utilization in scholarly domain. Based on scholarly literature, the study presents a complete assessment of current state-of-the-art techniques. We presented an analytical methodology to investigate the existing status of scholarly knowledge graphs (SKG) by structuring scholarly communication. This review paper investigates the field of applying machine learning, rule-based learning, and natural language processing tools and approaches to construct SKG. It further presents the review of knowledge graph utilization and refinement to provide a view of current research efforts. In addition, we offer existing applications and challenges across the board in construction, refinement and utilization collectively. This research will help to identify frontier trends of SKG which will motivate future researchers to carry forward their work.
