       PURPOSE: To evaluate the key topics and emerging trends in the field of cardiorenal syndrome type 4 (CRS-4) by bibliometrics and visual analysis.
    METHODS: Citespace, VOSviewer, and Bibliometrix package were used to analyze the collected data from the Web of Science Core Collection, including publication trends, leading countries, active authors and institutions, co-cited references, journals, and keyword analysis.
    RESULTS: Finally, 2267 articles were obtained. From 2004 to 2022, the number of publications was increasing year by year. A total of 735 authors from 543 institutions in 94 countries/regions participated in the publication of CRS-4 field, which were mostly from North America and Europe. Most of the co-cited references were reviews or guidelines from kidney/heart specialist journals or top journals. The journals concerning nephrology had a higher academic influence in this field. Oxidative stress and inflammation remained hot topics in CRS-4 research, as well as uremic toxins. Fibroblast growth factor 23 and klotho were emerging trends in recent years. Sodium glucose cotransporter 2 (SGLT2) inhibitors were the latest frontier hot spots. Future research advances may pay more attention to the prevention and prognosis assessment of CRS-4.
    CONCLUSION: Our study provides some key information for scholars to determine the direction of future research.

      With the global acceptance of endovascular aortic repair (EVAR) for aortic diseases, one of the most common issues in EVAR is the preservation of critical aortic branches. Despite the fact that many studies on EVAR-assisted endovascular branch reconstruction techniques have been published. There were few bibliometric analyses that focused on branch rebuilding in endovascular aortic repair. In this study, we aim to analyze the characteristics of the 100 most-cited articles on branch reconstruction in Endovascular Aortic Repair. The most popular articles retrospectively searched on the Web of Science were published between 1999 and 2018, with 10480 citations in total (an average of 551.58 citations per year). The top-cited article was 281 citations. The peak years of citations was 2019 (1051 citations). Journal of Vascular Surgery published the most articles (46 articles) and was the most-cited journal (5055 citations), and the United States was the country with the greatest number of publications (43 articles). Cleveland Clinic was the most influential institution with 20 articles. Fenestration technique was the major topic area of interest and trend (63 articles mentioned). Customised device was the most widely used endograft (52 articles mentioned). Renal artery was the most frequently reconstructed branch of aorta (70 articles mentioned). Our analysis showed the endovascular branch reconstruction in EVAR developed rapidly over the past 20 years. Continued exploration and cooperation between specialties and manufacturers on endograft design and modifications will further enhance knowledge of disease intervention and treatment.

       BACKGROUND: Cirrhosis results from persistent liver injury that leads to liver fibrosis. Immunological factors play important regulatory roles in the development and progression of cirrhosis. Bibliometrics is one of the most commonly used methods for systematic evaluation of a field of study. To date, there are no bibliometric studies on the role of immunological factors in cirrhosis.
    AIM: To provide a comprehensive overview of the knowledge structure and research hotspots of immunological factors in cirrhosis.
    METHODS: We retrieved publications related to immunological factors in cirrhosis between 2003 to 2022 from the Web of Science Core Collection database on December 7, 2022. The search strategy was TS = ((Liver Cirrhosis OR hepatic cirrhosis OR liver fibrosis) AND (Immunologic* Factor* OR Immune Factor* OR Immunomodulator* OR Biological Response Modifier* OR Biomodulator*)). Only original articles and reviews were included. A total of 2873 publications were analyzed using indicators of publication and citation metrics, countries, institutes, authors, journals, references, and keywords by CiteSpace and VOSviewer.
    RESULTS: A total of 5104 authors from 1173 institutions across 51 countries published 2873 papers on cirrhosis and immunological factors in 281 journals. In the past 20 years, the increasing number of related annual publications and citations indicates that research on immunological factors in cirrhosis has become the focus of attention and has entered a period of accelerated development. The United States (781/27.18%), China (538/18.73%), and Germany (300/10.44%) were the leading countries in this field. Most of the top 10 authors were from the United States (4) and Germany (3), with Gershwin ME contributing the most related articles (42). World Journal of Gastroenterology was the most productive journal, whereas Hepatology was the most co-cited journal. Current research hotspots regarding immunological factors in cirrhosis include fibrosis, cirrhosis, inflammation, liver fibrosis, expression, hepatocellular carcinoma, activation, primary biliary cirrhosis, disease, and hepatic stellate cells. Burst keywords (e.g., epidemiology, gut microbiota, and pathways) represent research frontiers that have attracted the interest of researchers in recent years.
    CONCLUSION: This bibliometric study comprehensively summarizes the research developments and directions of immunological factors in cirrhosis, providing new ideas for promoting scientific research and clinical applications.

       Background: Melanoma is a skin tumor with a high mortality rate, and early diagnosis and effective treatment are the key to reduce its mortality rate. Therefore, more and more attention has been paid for biomarker identification for early diagnosis, prognosis prediction and prognosis evaluation of melanoma. However, there is still a lack of a report that comprehensively and objectively evaluates the research status of melanoma biomarkers. Therefore, this study aims to intuitively analyze the research status and trend of melanoma biomarkers through the methods of bibliometrics and knowledge graph.
    Objective: This study uses bibliometrics to analyze research in biomarkers in melanoma, summarize the field's history and current status of research, and predict future research directions.
    Method: Articles and Reviews related to melanoma biomarkers were retrieved by using Web of Science core collection subject search. Bibliometric analysis was performed in Excel 365, CiteSpace, VOSviewer and Bibliometrix (R-Tool of R-Studio).
    Result: A total of 5584 documents from 2004 to 2022 were included in the bibliometric analysis. The results show that the number of publications and the frequency of citations in this field are increasing year by year, and the frequency of citations has increased rapidly after 2018. The United States is the most productive and influential country in this field, with the largest number of publications and institutions with high citation frequency. Caroline Robert, F. Stephen Hodi, Suzanne L. Topalian and others are authoritative authors in this field, and The New England Journal of Medicine, Journal of Clinical Oncology and Clinical Cancer Research are the most authoritative journals in this field. Biomarkers related to the diagnosis, treatment and prognosis of melanoma are hot topics and cutting-edge hotspots in this field.
    Conclusion: For the first time, this study used the bibliometric method to visualize the research in the field of melanoma biomarkers, revealing the trends and frontiers of melanoma biomarkers research, which provides a useful reference for scholars to find key research issues and partners.

       BACKGROUND: As the complexity and diversity of the tumor immune microenvironment (TIME) are becoming better understood, burgeoning research has progressed in this field. However, there is a scarcity of literature specifically focused on the bibliometric analysis of this topic. This study sought to investigate the development pattern of TIME-related research from 2006 to September 14, 2022, from a bibliometric perspective.
    METHODS: We acquired both articles and reviews related to TIME from the Web of Science Core Collection (WoSCC) (retrieved on September 14, 2022). R package "Bibliometrix" was used to calculate the basic bibliometric features, present the collaborative conditions of countries and authors, and generate a three-field plot to show the relationships among authors, affiliations, and keywords. VOSviewer was utilized for co-authorship analysis of country and institution and keyword co-occurrence analysis. CiteSpace was used for citation burst analysis of keywords and cited references. In addition, Microsoft Office Excel 2019 was used to develop an exponential model to fit the cumulative publication numbers.
    RESULTS: A total of 2545 publications on TIME were included, and the annual publication trend exhibited a significant increase over time. China and Fudan University were the most productive country and institution, with the highest number of publications of 1495 and 396, respectively. Frontiers in Oncology held the highest number of publications. A number of authors were recognized as the main contributors in this field. The clustering analysis revealed six clusters of keywords that highlighted the research hot spots in the fields of basic medical research, immunotherapy, and various cancer types separately.
    CONCLUSIONS: This research analyzed 16 years of TIME-related research and sketched out a basic knowledge framework that includes publications, countries, journals, authors, institutions, and keywords. The finding revealed that the current research hot spots of the TIME domain lie in "TIME and cancer prognosis", "cancer immunotherapy", and "immune checkpoint". Our researchers identified the following areas: "immune checkpoint-based immunotherapy", "precise immunotherapy" and "immunocyte pattern", which may emerge as frontiers and focal points in the upcoming years, offering valuable avenues for further exploration.

       BACKGROUND: Recently, dupilumab has been used for the treatment of atopic dermatitis (AD), and growing interest in the subject has resulted in an increasing number of publications.
    OBJECTIVES: Our study aimed to evaluate the rapid progress, identify hot topics, and explore scientific advances and future trends in this field.
    MATERIALS & METHODS: The global distribution of publications was estimated with no time restrictions. Dupilumab as a treatment for AD was scanned in the Web of Science core collection using the topic terms "dupilumab" and "atopic Dermatitis". VOSviewer was applied for visualization of bibliometric analysis. Analysis of country and region distribution, impact of journal, authors, population, economic estimation among countries and regions, key words, as well as the top 20 cited articles were performed.
    RESULTS: In total, 910 publications were yielded from the Web of Science core collection database. Most studies were published in the USA (46.15%), Germany (17.91%), and France (14.07%); other countries included Denmark, the Netherlands, and Canada based on normalization of article numbers according to population and economic evaluation. Studies were most frequently reported in the British Journal of Dermatology and the Journal of the American Academy of Dermatology. Pirozzi, G. from France was the top-cited author. The most frequent key words were concepts in dermatology, allergy, and immunology. Remarkable landmark clinical trials were noted in the top 20 cited publications.
    CONCLUSION: The research of dupilumab for AD is rapidly developing. Countries in North America and Europe have remarkably contributed to researches of dupilumab as a treatment for AD. The bibliometric analysis also presents hallmark publications reporting scientific advances in therapy progress, which may provide a foundation for further research.

      This paper offers a thorough bibliometric review of the literature on municipal solid waste compost (MSWC), focusing on the past two decades. Using an extensive dataset of 827 documents, the research patterns are analyzed via the R-based Bibliometrix package, merging metadata from Web of Science and Scopus. The analysis reveals substantial global growth in MSWC research, with a particular surge in the last 20 years. Discipline-specific journals are the main publishers, while multidisciplinary environmental outlets gained more citations. The study identifies five major collaborative author clusters that dominate productivity and citation frequency. The thematic evolution over the past five decades shows a transition from waste disposal towards topics such as heavy metals, soil properties, and plant nutrition, with emerging themes like carbon sequestration, biochar, and microplastics signaling future research directions. Specifically, the field has experienced a 7.86% annual growth rate, with an average citation rate of 26.88 per article. The 827 publications emerged from 317 sources and 1910 authors, with an international co-authorship rate of 14.75%, reflecting the field's interdisciplinary character. Thirteen primary sources and twenty-two key authors were identified as major contributors. On the geographical front, Spain and Italy led with the most contributions and highest citation count, respectively. In terms of keywords, "heavy metals" and "sewage sludge" were the most recurrent, indicating the prevailing topics in MSWC research. This analysis hence provides key insights into the evolution and future trajectory of MSWC studies.

      Bronchiolitis obliterans (BO) is a rare and irreversible chronic respiratory disease. The diagnosis of BO is challenging, and there still needs to be specific therapies and uniform treatment guidelines available. Research on BO has grown steadily over the past 20 years, and with the continued interest of researchers in this area, a bibliometric study of BO becomes necessary. This topic aims to assess the current state of research in BO over the last 2 decades and to identify research hotspots and emerging directions. Information on BO-related articles were obtained from the Science Citation Index Expand of the Web of Science Core Collection (WOSCC [SCI-E]) database. Citespace (6.1.R6), VOSviewer (1.6.18), and the online bibliometrics website (https://bibliometric.com/) were used for bibliometric analysis mainly to include country/region, institution, author, journal, keywords, and references and to construct visual knowledge network diagrams. A total of 4153 publications from the WOSCC [SCI-E] database were included in this study. Most publications come from the United States, Japan, and Germany, which collaborate relatively more frequently. Research institutions in the United States, especially the University of Washington, published the largest number of BO-related articles. Regarding authors, Vos, R is the most productive author, while Verleden, GM is the most influential in BO. In addition, JOURNAL OF HEART AND LUNG TRANSPLANTATION is the journal with the most published articles. The most cited article is Estenne M, 2002. Based on the clustering analysis of keywords and references, the diagnosis of bronchiolitis obliterans syndrome (BOS), treatment of BOS, and risk factors of BO are the current research hotspots and future research trends. We analyzed the publication trends in BO by bibliometrics and mapped the knowledge network of major contributing countries/regions, institutions, authors, and journals. Current research hotspots were found based on the main keywords and references. The outcome may help researchers identify potential collaborators, collaborating institutions, and hot fronts in BO to enhance collaboration on critical issues and improve the diagnosis and treatment of BO.

       BACKGROUND: A new approach to showcasing author publications on a website involves using a visual representation instead of the conventional paper list. The creation of an impact beam plot (IBP) as a research profile for individuals is crucial, especially when incorporating collection edges that include self-cited articles through a rare cluster analysis technique not commonly found in the literature. This study presents the application of a unique method called the following-leading clustering algorithm (FLCA) to generate IBPs for 3 highly productive authors.
    METHODS: For the 3 highly productive authors, Sung-Ho Jang from South Korea, Chia-Hung Kao from Taiwan, and Chin-Hsiao Tseng from Taiwan, all their published articles indexed in the Web of Science Core Collection were downloaded. Sung-Ho Jang published 593 articles, Chia-Hung Kao published 732 articles, and Chin-Hsiao Tseng published 160 articles. To analyze and showcase their publications, the FLCA was utilized. This algorithm helped cluster their articles and identify representative publications for each author. To assess the effectiveness and validity of the FLCA algorithm, both network charts and heatmaps with dendrograms were employed. IBPs were then created and compared for each of the 3 authors, taking into consideration their h-index, x-index, and self-citation rate. This allowed for a comprehensive visual representation of their research impact and citation patterns.
    RESULTS: The results show that these authors' h-index, x-index, and self-citation rates were (37, 44.01, 1.66%), (42, 61.47, 0.23%), and (37, 40.3, 6.62%), respectively. A higher value in these metrics indicates a more remarkable research achievement. A higher self-citation rate with a lower cluster number indicates that manuscripts are more likely to have been self-drafted. Using the FLCA algorithm, IBPs were successfully generated for each author.
    CONCLUSION: The FLCA algorithm allows for the easy generation of visual IBPs based on authors' publication profiles. These IBPs incorporate 3 important bibliometric metrics: h-index, x-index, and self-citations. These metrics are highly recommended for use by researchers globally, particularly with the self-citation rate, as they offer valuable insights into the scholarly impact and citation patterns of individual researchers.

       Background: There is a wide range of literature on patellar tendon injury, making it increasingly difficult to stay informed on the most influential studies in this field. It is essential to be familiar with the foundational articles of patellar tendon injury research to understand the current state of the literature and deliver high quality care.
    Purpose: To objectively identify the 50 most influential articles relating to patellar tendon injury and conduct a bibliometric analysis to identify key features of these articles.
    Study Design: Cross-sectional study.
    Methods: The Clarivate Analytics Web of Knowledge database was utilized to gather metrics on the 50 most cited articles on patellar tendon injury on June 27, 2022. The information extracted from each article included publication year, number of citations, author information, article type, level of evidence, country of origin, journal name, study focus, and industry influence.
    Results: The top 50 studies were cited a total of 8543 times and published between 1977 and 2015. The majority of articles were published after 2003, and the majority of citations were accrued after 2011. The most prevalent article types were cohort studies (n = 23), and the majority of studies were of evidence level 2 (n = 14) or 4 (n = 13). Australia and the United States (US) each published the most studies (n = 11). Only 4 (8%) studies focused on patellar tendon rupture, and 12 (24%) of the top 50 studies were associated with industry.
    Conclusion: The majority of the top 50 most influential articles in patellar tendon injury were published and accumulated citations in the past 10 to 20 years. Non-US countries, institutions, and journals published many of the top 50 studies, reflecting a global interest and commitment to research in this field. Patellar tendon rupture and surgical repair represents a minority of research in the top 50 studies and could be a point of growth in the future.

       Introduction: Optogenetics is a rapidly developing field combining optics and genetics, with promising applications in neuroscience and beyond. However, there is currently a lack of bibliometric analyses examining publications in this area.
    Method: Publications on optogenetics were gathered from the Web of Science Core Collection Database. A quantitative analysis was conducted to gain insights into the annual scientific output, and distribution of authors, journals, subject categories, countries, and institutions. Additionally, qualitative analysis, such as co-occurrence network analysis, thematic analysis, and theme evolution, were performed to identify the main areas and trends of optogenetics articles.
    Results: A total of 6,824 publications were included for analysis. The number of articles has rapidly grown since 2010, with an annual growth rate of 52.82%. Deisseroth K, Boyden ES, and Hegemann P were the most prolific contributors to the field. The United States contributed the most articles (3,051 articles), followed by China (623 articles). A majority of optogenetics-related articles are published in high-quality journals, including NATURE, SCIENCE, and CELL. These articles mainly belong to four subjects: neurosciences, biochemistry and molecular biology, neuroimaging, and materials science. Co-occurrence keyword network analysis identified three clusters: optogenetic components and techniques, optogenetics and neural circuitry, optogenetics and disease.
    Conclusion: The results suggest that optogenetics research is flourishing, focusing on optogenetic techniques and their applications in neural circuitry exploration and disease intervention. Optogenetics is expected to remain a hot topic in various fields in the future.

      The tobacco epidemic is affecting 8 million people with 1.2 million deaths worldwide. The Framework Convention on Tobacco Control (FCTC) was adopted by the World Health Organization (WHO) Member States in 2003 to counter the growing tobacco menace. Articles 11 and 13 of WHO FCTC suggest plain packaging of tobacco products to reduce the visibility and make tobacco products look less attractive. The current bibliometric analysis was conducted to analyze the visibility and impact of the scientific productions contributing to plain packaging globally. The bibliometric analysis allowed a quantitative analysis of all scientific publications indexed in Scopus. The sample was defined using the keywords "plain packaging OR standardized packaging" AND "tobacco." Five broad bibliometric domains were assessed for analysis: namely, scientific production, authors, sources or journals, countries, and thematic areas using R programming v4.2.2 and VOSviewer. The total number of documents published regarding plain packaging in tobacco control from 1992 till mid-2022 was determined. Australia tops the list with 99 publications, followed by the United Kingdom, United States, New Zealand, Canada, France, India, Netherlands, Spain, and Egypt. The author citation network showcases the link between the 21 top documents, with a minimum of 50 citations per document. The two main indicators assessed were the total number of articles published in the journal and the h index. Bibliometric indicators in this study illustrated that scientific publications/efforts to implement the WHO FCTC guideline concerning plain packing laws were neglected in most countries.

      The purpose of this review was to explore the 20 most cited articles on prosthetic complications with dental implants. Identification of such articles could be helpful in prosthodontics residency programmes in devising the curriculum of essential reading material in implantology. The Institute for Scientific Information, Web of Science Database, and Google Scholar were used to identify the 20 top-cited articles published in journals from 1980 till June 2021. These articles were then evaluated according to the number of citations, authors, study design, publication year, and publishing journal. Descriptive statistics were computed for bibliometrics. It was observed that the citation count ranged from 6,391 to 315 (in descending order). The Toronto study is the most cited study on dental implant prosthetic complications. Prospective studies and systematic and narrative reviews were the predominant study designs used in the articles; however, alarmingly no randomised controlled trials were included in the list.

      This study aimed to evaluate and pinpoint the status, hot areas, and frontiers of immune activation during HIV infection utilizing CiteSpace. From 1990 to 2022, we searched for studies on immune activation during HIV infection in the Web of Science Core Collection. CiteSpace was used to visually analyze the publications to identify the research status and pertinent research hotspots and frontiers in terms of the countries, institutions, authors, references, journals, and keywords. The Web of Science Core Collection yielded 5321 articles on immune activation during HIV infection. With 2854 and 364 articles, the United States and the University of California, San Francisco were the leading nation and institution in this domain. Steven G. Deeks has published 95 papers and is the most published author. The top cited articles on microbial translocation as a significant factor during HIV infection were published by Brenchley et al. Research on molecular/biology/genetics is often referenced in publications in the journals of molecular/biology/immunology. Inflammation, risk, mortality, cardiovascular disease, persistence, and biomarkers will be high-frequency words that are hot topics of research. According to the results, there was a strong collaboration between countries and organizations but little collaboration among authors. Molecular biology, immunology, and medicine are the main study subjects. The current hot topics in research are inflammation, risk, mortality, cardiovascular disease, persistence, and biomarkers. Future studies should concentrate on reducing the pathological changes caused by inflammation and altering the mechanisms of immune activation to reduce the size of the viral reservoir.

       Background: To carry out a bibliometric analysis of robotic surgery research in the field of breast cancer conducted between 2008 and 2022 and to evaluate the status and trends in the field.
    Methods: A systematic search was undertaken in the Web of Science (WoS) for published articles related to surgical robots and breast cancer. R and VOSviewer software were used to carry out a quantitative analysis to explore the trend of annual publication volume and the cooperative relationship between countries, institutions, authors, and keywords.
    Results: A total of 177 publications were retrieved, 79.66% of which were published from 2016 to 2022, and most were conducted in the United States (US), China, and South Korea. Articles from the US had the most frequent international cooperation. A tally of institutional publications showed that Yonsei University (YONSEI UNIV; Korea) had produced the most publications. The author with the most published papers was Lee of YONSEI UNIV. The most accepted journal was the Asian Journal of Surgery. Keyword co-occurrence analysis showed that current research hotspots were mainly focused on nipple-conserving mastectomy and breast reconstruction, and breast-conserving and nipple-conserving mastectomy may be future research hotspots.
    Conclusions: The annual incidence of robotic surgery and breast cancer is gradually increasing. The predominant countries conducting research in this field include the US, China, and South Korea, and the institutions are mainly distributed in universities and hospitals. Nipple-conserving mastectomy and breast reconstruction may be the current research hotspots, and breast-conserving mastectomy and minimally invasive surgery may represent hot research areas in the future. These findings may help scholars who are committed to the application of surgical robots to breast cancer to better understand the current research status and trends.

       Background: Injury is one of the leading causes of mortality and disability worldwide. It is a major contributor to the overall burden of disease. This study aimed to analyze the temporal trend, research focus and future direction of research related to injury burden.
    Methods: Publications on injury burden published between January 1998 and September 2022 were extracted from the Web of Science Core Collection (WoSCC) through topic advanced search strategy. Microsoft Excel, RStudio, VOSviewer, and CiteSpace were used to extract, integrate, and visualize bibliometric information.
    Results: A total of 2916 articles and 783 reviews were identified. The number of publications on injury burden showed a steady upward trend. The United States of America (USA) (n=1628) and the University of Washington (n=1036) were the most productive country and institution. High-income countries started research in this domain earlier, while research in low- and middle-income countries began in recent years. Lancet was the most influential journal. Public, environmental occupational health, general medicine and neurology were the predominant research domains. Based on keyword co-occurrence analysis, the research focus was divided into five clusters: injury epidemiology and prevention, studies related to the global burden of disease (GBD), risk factors for injury, clinical management of injury, and injury outcome assessment and economic burden.
    Conclusion: The burden of injury has drawn increasing attention from various perspectives over the years. The research field on injury burden is also becoming more and more extensive. However, there are some gaps among different countries or regions, and more attention needs to be paid to low and middle-income countries.

      The uncooperative behavior of children in the dental office has increased the demand for pharmacological behavior management techniques. Moderate sedation is more effective by providing analgesia and anxiolysis, thereby aiding in carrying out the most comfortable, efficient, and high-quality dental services. There is a need to understand the various aspects such as the choice of drug, method of drug administration, safety, and efficacy. Bibliometrics can reveal significant shifts in research and publication trends. Therefore, this study aimed to perform a bibliometric analysis of the literature on evolving trends in conscious sedation at pediatric dental offices. The bibliometric research used RStudio 2021.09.0+351 for Windows (RStudio, Boston, MA), package "bibliometrix," and VOS viewer software (Centre for Science and Technology Studies, Leiden University, The Netherlands. https://www.vosviewer.com). Elsevier's Scopus database (www.scopus.com) provided the literary data for this study, which were exported in BibTex format. The articles were independently categorized according to the following aspects: (a) annual scholarly output; (b) leading countries or regions; (c) leading journals; (d) productive authors; (e) citations; (f) study design; and (g) distribution of topics. The findings considered 1996 through 2022 and used journals, books, articles, and other sources, totaling 1064 papers, with an average of 10.7 per year. According to the findings, the United States, the United Kingdom, and India were principally leading the field of conscious sedation research. In total, 2433 authors were found through the search. The study identified the nations that are currently researching the topics such as midazolam and nitrous-oxide; this paves the way for future partnerships to strengthen the evidence generated in other topic areas using novel sedatives and exploring the different routes of drug administration, thereby benefiting the scientific community by identifying knowledge gaps and experts in this area of research.

       BACKGROUND: The first human monkeypox (MPX) case was identified in the Democratic Republic of Congo (DRC) in 1970 with an outbreak in 2010 and the first human MPX case in the UK in 2022. In this study, we conducted a bibliometric analysis of the literature on monkeypox based on the Web of Science Core Collection (WOSCC) of the Institute for Scientific Information (ISI) to identify relevant topics and trends in monkeypox research.
    METHODS: We searched the Web of Science from 1964 until July 14, 2022, for all publications using the keywords "Monkeypox" and "Monkeypox virus." Results were compared using numerous bibliometric methodologies and stratified by journal, author, year, institution, and country-specific metrics.
    RESULTS: Out of 1170 publications initially selected, 1163 entered our analysis, with 65.26 % (n = 759) being original research articles and 9.37 % (n = 109) being review articles. Most MPX publications were in 2010, with 6.02 % (n = 70), followed by 2009 and 2022 at 5.67 % (n = 66) each. The USA was the country with the highest number of publications, with n = 662 (56.92 %) of total publications, followed by Germany with n = 82 (7.05 %), the UK with n = 74 (6.36 %), and Congo with n = 65 (5.59 %). Journal of Virology published the highest number of MPX publications, followed by Virology Journal and Emerging Infectious Diseases with n = 52 (9.25 %), n = 43 (7.65 %), and n = 32 (5.69 %) publications, respectively. The top contributing institutions were the Centers for Disease Control and Prevention (CDC), the US Army Medical Research Institute of Infectious Diseases, and the National Institutes of Health (NIH)National Institute of Allergy and Infectious Diseases (NIAID).
    CONCLUSION: Our analysis provides an objective and robust overview of the current literature on MPX and its global trends; this information could serve as a reference guide for those aiming to conduct further MPX-related research and as a source for those seeking information about MPX.

       BACKGROUND: Despite the global acceptance of the impact factor (IF) by researchers and academic institutions as one, criticism has been voiced regarding its effectiveness in evaluating the unbiased impact of a journal. To overcome the limitations and drawbacks of the IF that were presented by the scientific community, they introduced several other citation-based bibliometric indices.
    METHODS: All plastic and reconstructive surgery journals were analyzed, and bibliometric indices were extracted from the relevant source. Pearson correlation coefficients were used to determine correlations between the various indices.
    RESULTS: All correlations in between the various bibliometric indices were found to be positively and statistically significant, ranging from moderately highly associated for the IF and Eigenfactor (r = 0.632) to very strongly associated (r = 0.962) for the IF and the Article Influence Score.
    CONCLUSION: In the field of plastic and reconstructive surgery, the Eigenfactor and its derivative, the Article Influence Score, could potentially serve as better indices than the IF in demonstrating the overall picture. This information is based on the inclusion of a greater number of journals in the calculation and subtraction of self-citations, without compromising their correlation with other indices.The use of Eigenfactor and other additional bibliometrics cooperatively with the IF could provide the most extensive evaluation of a journal's scientific impact.

      The impact of air pollution is one of the hotspots attracting continuous scholarly attention, but the comprehensive statistical and visual analysis reviews are few. Employing the method of bibliometric analysis, this paper took the relevant literature from 1996 to April 2022 on the Web of Science as the research object. Through the methods of keyword co-occurrence analysis and burst analysis, the spatiotemporal evolution trend, cooperation network, outstanding scholars, knowledge base, and research focus of air pollution impact research are visually presented. Via constructing a common word matrix of high-frequency words, clustering analysis is used to aggregate high-frequency keywords into 24 clusters. By the strategic coordinate analysis method, the relationships within and between clusters were revealed. The main findings include (1) research on the impact of air pollution mainly focusing on human health; (2) the six keywords with the highest centrality are California, hydrocarbons, dioxide, generation, Asia, and diesel; (3) these 11 clusters may be developed into future research hotspots: particulate matter, nitrogen oxides, mortality, ozone, pollution, air quality, asthma, children, epidemiology, aerosols, and polycyclic aromatic hydrocarbons; and (4) seven topics are research hot: daily mortality, long-term exposure, coronary heart disease, concentration, North China plain, traffic-related air pollution, and air pollution.

      We aimed to identify the trends and patterns of robotic surgery research in obstetrics and gynecology since its implementation. We used data from Clarivate's Web of Science platform to identify all articles published on robotic surgery in obstetrics and gynecology. A total of 838 publications were included in the analysis. Of these, 485 (57.9%) were from North America and 281 (26.0%) from Europe. 788 (94.0%) articles originated in high-income countries and none from low-income countries. The number of publications per year reached a peak of 69 articles in 2014. The subject of 344 (41.1%) of articles was gynecologic oncology, followed by benign gynecology (n = 176, 21.0%) and urogynecology (n = 156, 18.6%). Articles discussing gynecologic oncology had lower representation in low- and middle-income countries (LMIC) (32.0% vs. 41.6%, p < 0.001) compared with high income countries. After 2015 there has been a higher representation of publications from Asia (19.7% vs. 7.7%) and from LMIC (8.4% vs. 2.6%), compared to the preceding years. In a multivariable regression analysis, journal's impact factor [aOR 95% CI 1.30 (1.16-1.41)], gynecologic oncology subject [aOR 95% CI 1.73 (1.06-2.81)] and randomized controlled trials [aOR 95% CI 3.67 (1.47-9.16)] were associated with higher number of citations per year. In conclusion, robotic surgery research in obstetrics & gynecology is dominated by research in gynecologic oncology and reached a peak nearly a decade ago. The disparity in the quantity and quality of robotic research between high income countries and LMIC raises concerns regarding the access of the latter to high quality healthcare resources such as robotic surgery.

      As an unconventional natural gas, the calorific value of coal seam gas (CSG) is equivalent to that of natural gas. It is a high-quality, clean, and efficient green low-carbon energy source. Coal seam hydraulic fracturing is an important permeability enhancement measure in the process of CSG drainage. In order to further understand the overall research progress in the field of coal seam hydraulic fracturing, the Web of Science (WOS) database is used as a sample source, and the bibliometric analysis of the literature is carried out by CiteSpace software. The visual knowledge maps of the number of publications, the research countries, institutions, and keyword clustering are drawn. The research shows that it has gone through two stages of slow development and rapid growth in terms of time distribution. In terms of cooperation networks, the main active countries include China, the USA, Australia, Russia, and Canada, composed of China University of Mining and Technology, Chongqing University, Henan Polytechnic University, and China University of Petroleum as the core research institutions. Taking keywords as the theme, the coal seam hydraulic fracturing research field mainly involves high-frequency keywords such as hydraulic fracturing, permeability, model, and numerical simulation. The hotspot evolution law and frontier development trend of keywords with time are analyzed and obtained. On this basis, from a new perspective, the "scientific research landscape map" in the field of coal seam hydraulic fracturing is outlined, in order to provide a scientific reference for the research in this field.

      Unsaturated polyester resin (UPR) is one of the first commercialized polymer matrices for composites reinforced with glass fibers, but has remained popular to this day. To reduce their environmental impact, natural fibers have been used as reinforcements. Researchers all over the world are still interested in these composites, and numerous papers have been published in the last four decades. Using bibliometric analysis, this work provides compiled, structured, and relevant information about the evolution and current state of these materials. This first study on UPR biocomposites based on bibliometric analysis examined 531 published papers identified in the Scopus database from 1982 to July 2022. An analysis of the most active states, leading institutions, and leading authors is followed by the identification of key areas such as the most common natural fibers used as reinforcements, fiber treatments, and composite design parameters such as processing techniques; recently, composite testing; and technological applications. The findings emphasize the importance of staying active in this global field and provide information on novel promising topics for future research.

       OBJECTIVES: Quantification of academic productivity relies on bibliometric measurements, such as the Hirsch index (h-index). The National Institutes of Health (NIH) recently developed the relative citation ratio (RCR), an article-level, citation-driven metric that compares researchers with others within their respective fields. Our study is the first to compare the usage of RCR in academic otolaryngology.
    STUDY DESIGN: Retrospective Database Review.
    METHODS: Academic otolaryngology residency programs were identified using the 2022 Fellowship and Residency Electronic Interactive Database. Demographic and training data were collected for surgeons using institutional websites. RCR was calculated using the NIH iCite tool, and h-index was calculated using Scopus. Mean RCR (m-RCR) is the average score of the author's articles. Weighted RCR (w-RCR) is the sum of all article scores. These derivatives are a measure of impact and output, respectively. The career duration of a physician was categorized into the following cohorts: 0-10, 11-20, 21-30, and 31+ years.
    RESULTS: A total of 1949 academic otolaryngologists were identified. Men had higher h-indices and w-RCRs than women (both p less than 0.001). m-RCR was not different between genders (p = 0.083). There was a difference in h-index and w-RCR (both p less than 0.001) among the career duration cohorts, but there was no difference in m-RCR among the cohorts (p = 0.416). The faculty rank professor was the greatest for all metrics (p < 0.001).
    CONCLUSION: Critics of the h-index argue that it is reflective of the time a researcher has spent in the field, instead of impact. The RCR may reduce historic bias against women and younger otolaryngologists.

       OBJECTIVE: The current study investigated the contribution of the dissertations produced in the field of cardiology to the scientific literature and the factors affecting the publication process.
    METHODS: The study included 1049 cardiology dissertations archived in the national thesis center database between January 2010 and December 2017. The titles (English and Turkish), abstracts, and author names of cardiology dissertations were searched in Google Academic, TR Directory, and PubMed Central databases. In addition to their publication rates, the subject of the cardiology dissertations, the type of research, the type of institution, the academic title of the cardiology dissertation advisors, the duration of publication, the index of the published journals, and the quartile ranking of the Science Citation Index and Science Citation Index Expanded journals were examined.
    RESULTS: Among the reviewed 1049 cardiology dissertations 42.7% (n = 448) were published in a journal. The publication rate of cardiology dissertations among male authors was 43.5% and among female authors 40.1%. The cardiology dissertations were published at the highest rate after the 60th month. Among the published cardiology dissertations, 63.4% (n = 284) appeared in journals indexed by the Science Citation Index and Science Citation Index Expanded. There was no statistically significant relationship between the academic titles of cardiology dissertation advisors and the quartile ranking of Science Citation Index and Science Citation Index Expanded journals (P = 0.072).
    CONCLUSIONS: There were difficulties in transforming into a publication of dissertations in the field of cardiology to gain an academic identity. Incentives should be created to increase the desire and motivation of the residents.

       BACKGROUND: NIH funding to address basic reproductive health for common female conditions remains disproportionately low, in part due to low success rates of grant applications by obstetrician-gynecologists.
    OBJECTIVE: To evaluate the scholarly productivity of individuals supported by the National Institutes of Health (NIH) Child Health and Human Development Women's Reproductive Health Research (WRHR) K12 career development award (CDA), created to advance careers of obstetrician-gynecologist physician-scientists.
    STUDY DESIGN: We performed a cohort study of individuals who completed at least 2 years of WRHR training by June 30, 2015 and had at least 5 years follow-up. Earliest training start date was December 1, 1998. Primary outcomes from public data sources (NIH RePORTER, PubMed, iCite) were: 1) number of total and R01 NIH grants as PI; 2) numbers of total, first and last author publications; and 3) median and highest publication impact factor measured by the relative citation ratio (RCR). Secondary outcomes from an email survey subcohort were: total number of research grants, federally funded grants, and number of NIH grants as co-investigator; institutional promotions and academic appointments, national and NIH leadership roles; career and mentorship satisfaction. Outcomes were recorded at 5, 10, and 15 years post-graduation and aggregate anonymized data divided into 3 groups using WRHR completion dates: June 30 of 2005, 2010 and 2015. Temporal trends were assessed. Results were stratified by gender and by institutions funded for 5-year cycles (1-2 vs 3-4). Analyses used Fisher exact or Pearson chi-square tests, and Mantel-Haenszel tests of trend.
    RESULTS: The distribution of the cohort (N=178) by graduation completion date was: on or before June 30, 2005 [57(32%)]; July 1 2005-June 30, 2010 [60(34%)] and July 1, 2010-June 30, 2015 [61(34%)]. The majority were female [112(64%)]. Most were maternal fetal medicine trained [53(30%)], followed by no fellowship [50(28%)]. Of the 178, 72 (40%) received additional NIH funding as a PI, 45 (25%) received at least one R01 and 23 (13%) received 2-5 R01s. Mean estimates of the proportion of scholars was 52(31%) with >10 first author publications, 66(39%) with >10 last author publications and 108(63%) had > 25 publications. The highest RCR score was a median of 8.07 [IQR 4.20,15.16]. There were 121(71%) with RCR >5, indicating over 5-fold greater publication impact than other NIH-funded scientists in similar area of research. No differences by gender, institution or temporal trends were observed. Of the full cohort, 69 (45.7%) responded to the survey: the majority self-identified as women [50(73%)] and White [51(74%)].
    CONCLUSION: Our findings suggest that the infrastructure provided by an institutional K award is an advantageous CDA mechanism for obstetrician-gynecologists, a group of predominantly women surgeons. It may serve as a corrective for the known inequities in NIH funding by gender.

       BACKGROUND: We visually assessed the research hotspots of familial hypercholesterolemia (FH) using bibliometrics and knowledge mapping in light of the research state and development trend of FH.
    METHODS: We employed bibliometric tools, such as CiteSpace and the alluvial generator, to illustrate the scientific accomplishments on FH by extracting pertinent literature on FH from the Web of Science Core Collection database from January 1, 2002, to December 31, 2022.
    RESULTS: A total of 4402 papers in total were selected for study; 29.2% of all articles globally were from the USA, followed by the Netherlands and England. The University of Amsterdam, University of Oslo, and University of Western Australia are the 3 institutions with the most publications in this area. Gerald F. Watts, Raul D. Santos, and John J. P. Kastelein wrote the majority of the pieces that were published. The New England Journal of Medicine, Circulation, and Atherosclerosis were the journals with the greatest number of papers in this field. Prevalence and genetic analysis of FH, proprotein convertase subtilisin/kexin 9 inhibitors, and inclisiran are current research hotspots for the condition. Future research in this area will be focused on gene therapy.
    CONCLUSIONS: FH research has shown shows a trend of ascending followed by leveling off. The prevalence and diagnosis of FH, proprotein convertase subtilisin/kexin 9 inhibitors, inclisiran, and gene therapy are current research hotspots. This report may serve as a reference for current research trends.

       Objective: To reveal the characteristics, development trend and potential opportunities of China-ASEAN collaboration in the medical and health field based on bibliometrics.
    Methods: Scopus and International Center for the Study of Research Lab (ICSR Lab) was used to analyze the scale, collaboration network and distribution, impact of cooperative papers, collaboration dominance and evolution of the literature on China-ASEAN medical and health collaboration in the Scopus database from 1992 to 2022.
    Results: From 1992 to 2022, 19,764 articles on medical and health collaboration between China and ASEAN were filtered for analysis. The number of China-ASEAN collaborations has shown a clear upward trend over the years, indicating a gradually closer and improved collaboration relationship overall. The institutional collaboration network between China and ASEAN countries was obviously clustered, and the network connectivity was limited. The substantial differences between the median and mean values of citation impact of China-ASEAN medical and health research collaboration reflected that the collaboration was 'less' but 'better'. The dominance share of collaboration between China and the main ASEAN countries was fluctuating upward and has become more and more stable after 2004. Most of the China-ASEAN collaboration focused on their own characteristic research topics. In recent years, collaboration in infectious diseases and public health had expanded significantly, while other research topics had maintained in a complementary development trend.
    Conclusion: Collaboration between China and ASEAN in the medical and health field has exhibited a progressively closer relationship, and the trend of complementary research has remained stable. However, there are still areas of concern, including the limited scale of collaboration, narrow scope of participation and weak dominance.

      Artificial sweeteners have sparked a heated debate worldwide due to their ambiguous impacts on public and environmental health and food safety and quality. Many studies on artificial sweeteners have been conducted; however, none scientometric studies exist in the field. This study aimed to elaborate on the knowledge creation and development of the field of artificial sweeteners and predict the frontiers of knowledge based on bibliometrics. In particular, this study combined VOSviewer, CiteSpace, and Bibliometrix to visualize the mapping of knowledge production, covered 2389 relevant scientific publications (1945-2022), and systematically analyzed articles and reviews (n = 2101). Scientific publications on artificial sweeteners have been growing at an annual rate of 6.28% and globally attracting 7979 contributors. Susan J. Brown with total publications (TP) of 17, average citation per article (AC) of 36.59, and Hirsch (h)-index of 12 and Robert F. Margolskee (TP = 12; AC = 2046; h-index = 11) were the most influential scholars. This field was clustered into four groups: eco-environment and toxicology, physicochemical mechanisms, public health and risks, and nutrition metabolism. The publications about environmental issues, in particular, "surface water," were most intensive during the last five years (2018-2022). Artificial sweeteners are gaining importance in the monitoring and assessment of environmental and public health. Results of the dual-map overlay showed that the future research frontiers tilt toward molecular biology, immunology, veterinary and animal sciences, and medicine. Findings of this study are conducive to identifying knowledge gaps and future research directions for scholars.

      The generation of rock mass disasters in underground engineering essentially arises from the disruption of the original three-dimensional stress equilibrium of the rock mass caused by excavation and other activities, leading to the redistribution of stress fields. During the excavation process, the engineering rock mass undergoes complex dynamic stress equilibrium processes involving loading and unloading. This equilibrium process promotes the nucleation, initiation, and propagation of pre-existing cracks in the surrounding rock, resulting in changes in the internal structure of the rock mass and a weakening of its strength. Eventually, this localized cracking extends to global failure. In order to understand the current status better and study the development trends in the study of crack propagation and evolution in defective rock, this study conducts a bibliometric analysis of 288 articles from the Web of Science Core Collection database using CiteSpace software (version 6.1.R4). The results indicate an increasing trend in the annual publication output, characterized by two phases of emergence and rapid development. The countries of China, the United States, and Iran have the highest publication output in this field. The most frequently cited journals include INT J ROCK MECH MIN, ENG FRACT MECH, and ROCK MECH ROCK ENG. This study provides a comprehensive analysis of the current status and development trends in the research on the propagation and evolution of pre-existing cracks. This study enhances the comprehension of crucial aspects of crack propagation and evolution in rock materials with defects. Moreover, it opens up new possibilities for future investigations and holds promising implications for researchers and practitioners in the field.

       Introduction: Lateral anterior column release (ACR) is a minimally invasive option for the correction of sagittal plane deformity. To assemble a homogeneous picture of published research on ACR, an advanced bibliometric analysis was conducted to compile the top-ten most-cited articles on the topic of ACR.
    Methods: A keyword search using the Thomson Reuters Web of Knowledge was conducted to identify articles discussing the role of lateral ACR. The articles were then ranked based on the total number of citations to identify the ten most-cited articles published. A subjective appraisal of the findings of these articles was conducted to provide a ranked literature review and to examine trends in the study of ACR between 2012 and 2019.
    Results: The earliest published article on ACR was in 2012 by Deukmedjian et al. Three articles were in vitro biomechanical assessments of ACR, and seven articles were on outcome analyses, which were either case series or case controlled. The most-cited article was a biomechanical study authored by Uribe et al. The article with the highest rate of citations/year was authored by Manwaring et al. Uribe and the European Spine Journal were the most frequently cited author and journal, respectively.
    Conclusions: The lateral ACR approach has enjoyed significant scholarly attention since its advent. Higher-level analyses with robust control groups, larger sample sizes, and long-term follow-up are necessary to improve our understanding of this approach.

       BACKGROUND: To evaluate the number of citations for Cochrane Methodology Reviews after they have been updated or co-published in another journal, and the effect of co-publishing the review on the co-publishing journal's impact factor (IF).
    METHODS: We identified all Cochrane Methodology Reviews published in the Cochrane Database of Systematic Reviews (CDSR) before 2018 and searched for co-published versions in the Web of Science Core Collection database up to 16 August 2022. The included reviews were in two cohorts: those that had been published and updated in CDSR and those that had been published in CDSR and co-published in another journal. The primary outcome measured the citation number to updated and original reviews in the first five years after publication of the updated review, and assessed the citation number of co-published and non-co-published reviews in the first five years after publication of the co-published version. The secondary outcome was the ratio of an adjusted IF and the actual IF of the co-publishing journal.
    RESULTS: Eight updated and six original reviews were identified for the updated cohort of reviews, and four co-published reviews were included in the co-published cohort. The original reviews continued to be cited after the update was published but the median for the total number of citations was non-significantly higher for the updated reviews than for their original version[161 (Interquartile range (IQR) 85, 198) versus 113 (IQR 15, 433)]. The median number of total citations [362 (IQR 179, 840) versus 145 (IQR 75, 445)] and the median number of citations to the review in the first five years after co-publication combined and in each of those years was higher in the co-published group than in the non-co-published group. One of the three journals that co-published Reviews in the first year and two journals in the second year had a lower IF after co-publication.
    CONCLUSIONS: Earlier versions of Cochrane Methodology Reviews continue to be cited after an update is published, which raises doubts about whether those citing are using the most recent evidence or are aware of the update. Co-publication facilitates broader application and dissemination of Cochrane methodology evidence.

      Since the outbreak of COVID-19, researchers and clinicians have published scientific articles on the SARS-CoV-2 virus and its medical, organizational, financial, and psychological implications. However, many effects have been observed in the post-lockdown scenario. In this study, we adopted a scientometric-bibliometric approach to drawing the state of the art regarding the emotional and psychological effects of the pandemic after the lockdown. In Scopus, we found 791 papers that were subsequently analyzed using CiteSpace. The document co-citation analysis (DCA) computation generated a network of eight major clusters, each representing a central area of investigation. Specifically, one major cluster-cluster no. 1-focuses on the long-term effects of the COVID-19 pandemic and individuals' ability to develop adaptive coping mechanisms and resilience. The results allow us to frame the fields covered by researchers more precisely and the areas that still need more investigation.

      The global agri-food industry generates a large volume of waste annually, which causes both environmental and economic problems. Recently, there has been a growing interest in the use of agri-food wastes and by-products to produce self-sufficient fish feed. This study aimed to analyze the intellectual structure of the recent research on the utilization of agri-food wastes and by-products as self-sufficient fish feed materials based on 922 Scopus-indexed core collection documents from 252 journals written by 4420 authors from 73 countries with an annual growth rate of 18.65% over the last four years (2019-2022). This bibliometric study implemented knowledge domain visualization (KDV) using VOSViewer and Biblioshiny in the Bibliometrix R-package to investigate the basic scientometric profile of the selected fields. The results showed that Dawood M.A.O., with PageRanks of 0.0732, 19 total publications, 695 global citations from 2019 to 2022, and closeness values of 0.25, was the most productive author within the field. Subsequently, China was determined to be the most productive country (93 valid documents) and have the strongest collaboration network. Major research hotspots in the field included aquaculture and sustainable aquaculture, fish feed with agri-food waste, rainbow trout species, the development of a circular economy, probiotic applications, and cell signaling cytokines and peptides. This bibliometric study provides comprehensive information on the intellectual domain and research landscape on self-sufficient fish feed and also shows how interest in this research topic and similar ones is growing.

       INTRODUCTION: the presentation of research at a congress is an interesting means for scientific dissemination, but only with publication in an indexed journal does the data become accessible and disseminated. The conversion rate in published articles of abstracts presented at congresses is an indicator to assess the scientific quality of those events. The aim of this study is to evaluate bibliometric characteristics of abstracts presented at the Brazilian Congress of Coloproctology and to determine the factors that affect publication rates.
    METHODS: Retrospective evaluation of all abstracts presented at the Brazilian Congresses of Coloproctology from 2015 to 2019. Multiple databases were analyzed to estimate the conversion rate of the presented papers, as well as variables associated with the conversion of abstracts into full manuscripts through bivariate analysis and multivariate variables of these predictors.
    RESULTS: 1756 abstracts were analyzed. Most studies are retrospective, series or case reports, and even personal experience. The conversion rate was 6.9%. The presence of statistical analysis was twice as high for published abstracts as for unpublished ones.
    CONCLUSION: the data presented demonstrate a low scientific productivity of the specialty, since the research carried out is, for the most part, not published as complete manuscripts. The predictors of publication of abstracts were: multicenter studies, studies with statistical analysis, study designs with a higher level of evidence and studies awarded by the congress.

       Purpose: As an important management method of the global healthcare system, diagnosis related groups (DRGs) classify patients into different cost groups and pay more attention to the equitable distribution of medical resources and the quality of medical services. At present, most countries have used DRGs to help medical institutions and doctors to treat patients more accurately, avoid the waste of medical resources, and improve treatment efficiency.
    Methods: The Web of Science database was searched to collect all relevant literature on DRGs from 2013 to 2022. The literature information was imported into CiteSpace, Vosviewer, and Histcite for data analysis and visualization of the results. Analyze the cooperative relationship among the countries, institutions, journals, and authors. The usage trend of keywords; Highlight the content of the cited articles.
    Results: The number of articles published in this decade was stable, and the number of citations in 2014 was the highest. The United States and Germany, as the first countries to use the DRGs system, are ahead of other countries in terms of the number and quality of articles. We have carried out content research on the articles with high citations, and summarized the application range of DRGs; classification method; advantages and disadvantages of the application. In general, the development trend of DRGs in foreign countries is to continuously optimize the classification method, expand the scope of application, and improve the application effect. These provide support and reference for the improvement of medical services and the perfection of the medical insurance system.
    Conclusion: The application of DRGs can improve the quality and efficiency of medical services, and reduce the waste of medical expenses. It can also promote the rational allocation of medical resources and the equity of medical services. In the future, DRGs will pay more attention to the personalized diagnosis and treatment and fine management of patients, and the sharing and standardization of medical data, to promote the development of medical informatization.

      In recent years, much attention has been paid to the use of biopolymers as food packaging materials due to their important characteristics and properties. These include non-toxicity, ease of availability, biocompatibility, and biodegradability, indicating their potential as an alternative to conventional plastic packaging that has long been under environmental scrutiny. Given the current focus on sustainable development, it is imperative to develop studies on biopolymers as eco-friendly and sustainable food packaging materials. Therefore, the aim of this review is to explore trends and characteristics of biopolymer-based biodegradable films for food packaging, analyze the contribution of various journals and cooperation between countries, highlight the most influential authors and articles, and provide an overview of the social, environmental, and economic aspects of biodegradable films for food packaging. To achieve this goal, a bibliometric analysis and systematic review based on the PRISMA method were conducted. Relevant articles were carefully selected from the Scopus database. A bibliometric analysis was also conducted to discuss holistically, comprehensively, and objectively biodegradable films for food packaging. An increasing interest was found in this study, especially in the last 3 years with Brazil and China leading the number of papers on biodegradable films for food packaging, which were responsible for 20.4% and 12.5% of the published papers, respectively. The results of the keyword analysis based on the period revealed that the addition of bioactive compounds into packaging films is very promising because it can increase the quality and safety of packaged food. These results reveal that biodegradable films demonstrate a positive and promising trend as food packaging materials that are environmentally friendly and promote sustainability.

      In veterinary medicine, the concept of disease is critical because it related to the survivability rate of the veterinary, especially livestock. Chicken was the most popular livestock that was observed in veterinary medicine. However, veterinary books were less popular compared to article and conference paper in global academic. This study's goal was to look how was the depiction of topic disease was used in veterinary textbooks that were related to the embryo of chicken as well as the trend of that topic. This study gathered 90 books meta-data donwloaded from Scopus website in form of CSV file. The data were analyzed using Vosviewer and biblioshiny of R Studio software to see the topic trend, citation, and number of book pages. Literature review also used to see the depiction of disease inside samples. Result showed that authors' keywords, heart and disease were closely related with a keyword chicken embryo. Moreover, each book get at least 10-11 citations globally. Moreover, repetitive keywords used in abstract of samples of this study were cells/cell, gene, and human. Those repetitive words were closely related to a word disease. It could be means that cell of the embryo of chicken also played the important role in determining its resistance against disease.

      Background:With advances in technology, teledermatology (TD) research has increased. However, an updated comprehensive quantitative analysis of TD research, especially one that identifies emerging trends of TD research in the coronavirus disease 2019 (COVID-19) era, is lacking.Objective:To conduct a scientometric analysis of TD research documents between 2002 and 2021 and explore the emerging trends.Methods:CiteSpace was used to perform scientometric analysis and yielded visualized network maps with corresponding metric values. Emerging trends were identified mainly through burst detection of keywords/terms, co-cited reference clustering analysis, and structural variability analysis (SVA).Results:A total of 932 documents, containing 27,958 cited references were identified from 2002 to 2021. Most TD research was published in journals from the "Dermatology" and "Health Care Sciences & Services" categories. American, Australian, and European researchers contributed the most research and formed close collaborations. Keywords/terms with strong burst values to date were "primary care," "historical perspective," "emerging technique," "improve access," "mobile teledermoscopy (TDS)," "access," "skin cancer," "telehealth," "recent finding," "artificial intelligence (AI)," "dermatological care," and "dermatological condition." Co-cited reference clustering analysis showed that the recently active cluster labels included "COVID-19 pandemic," "skin cancer," "deep neural network," and "underserved population." The SVA identified two reviews (Tognetti et al. and Mckoy et al.) that may be highly cited in the future.Conclusion:During and after the COVID-19 era, emerging trends in research on TD (especially mobile TDS) may be related to skin cancer and AI as well as further exploration of primary care in underserved areas.

      With a sample of 228 psychology papers that failed to replicate, we tested whether the trajectory of citation patterns changes following the publication of a failure to replicate. Across models, we found consistent evidence that failing to replicate predicted lower future citations and that the size of this reduction increased over time. In a 14-y postpublication period, we estimated that the publication of a failed replication was associated with an average citation decline of 14% for original papers. These findings suggest that the publication of failed replications may contribute to a self-correcting science by decreasing scholars' reliance on unreplicable original findings.

       Introduction: Language production is a finely regulated process, with many aspects which still elude comprehension. From a motor perspective, speech involves over a hundred different muscles functioning in coordination. As science and technology evolve, new approaches are used to study speech production and treat its disorders, and there is growing interest in the use of non-invasive modulation by means of transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS).
    Methods: Here we analyzed data obtained from Scopus (Elsevier) using VOSViewer to provide an overview of bibliographic mapping of citation, co-occurrence of keywords, co-citation and bibliographic coupling of non-invasive brain stimulation (NIBS) use in speech research.
    Results: In total, 253 documents were found, being 55% from only three countries (USA, Germany and Italy), with emerging economies such as Brazil and China becoming relevant in this topic recently. Most documents were published in this last decade, with 2022 being the most productive yet, showing brain stimulation has untapped potential for the speech research field.
    Discussion: Keyword analysis indicates a move away from basic research on the motor control in healthy speech, toward clinical applications such as stuttering and aphasia treatment. We also observe a recent trend in cerebellar modulation for clinical treatment. Finally, we discuss how NIBS have established over the years and gained prominence as tools in speech therapy and research, and highlight potential methodological possibilities for future research.

      The Internet of vehicles (IoV) is an Internet-of-things-based network in the area of transportation. It comprises sensors, network communication, automation control, and data processing and enables connectivity between vehicles and other objects. This study performed main path analysis (MPA) to investigate the trajectory of research regarding the IoV. Studies were extracted from the Web of Science database, and citation networks among these studies were generated. MPA revealed that research in this field has mainly covered media access control, vehicle-to-vehicle channels, device-to-device communications, layers, non-orthogonal multiple access, and sixth-generation communications. Cluster analysis and data mining revealed that the main research topics related to the IoV included wireless channels, communication protocols, vehicular ad hoc networks, security and privacy, resource allocation and optimization, autonomous cruise control, deep learning, and edge computing. By using data mining and statistical analysis, we identified emerging research topics related to the IoV, namely blockchains, deep learning, edge computing, cloud computing, vehicular dynamics, and fifth- and sixth-generation mobile communications. These topics are likely to help drive innovation and the further development of IoV technologies and contribute to smart transportation, smart cities, and other applications. On the basis of the present results, this paper offers several predictions regarding the future of research regarding the IoV.

      Diversity is widely recognized as a driver of excellence and innovation. In recent years, women have become an increasingly significant part of the rheumatology workforce. We aimed to assess the gender representation of the leading rheumatology journals' editors and to explore whether editors' gender correlates with the gender of the first and last authors of published articles. We conducted a cross-sectional study and extracted editorial members of rheumatology journals in quartiles 1 to 3 (Clarivate Analytics) from each journal's website. We categorized editorial positions according to the level of influence in manuscript acceptance decision-making (levels I to III). The gender of editors and of the first and last authors in all 2019 original articles published in a sample of 15 rheumatology journals was assigned using a combination of digital gallery and manual searches. There were 2242 editors' names retrieved from 43 journals, 24 (26%) of the 94 editors at level I, 139 (36%) of 385 editors at level II, and 469 (27%) of 1763 at level III were female. The imbalance between journals was heterogeneous. Females were the first authors in 1342 (48%) and the last authors in 969 (35%) of the 2797 published articles. However, we found no significant correlation between editors' and authors' gender. Our data showed uneven gender representation on the editorial boards of most rheumatology journals, but we did not find any apparent vertical segregation or influence on publishing by gender. Our findings suggest that a generational transition may be occurring among authors.

       BACKGROUND: James Barrett Brown was one of the founders of Plastic and Reconstructive Surgery as a specialty in the United States. Susan Mackinnon started the James Barrett Brown Resident Research Day in 1997 in his honor to serve as an annual opportunity for trainees to present their research to the Division and a visiting contemporary leader in plastic surgery. We sought to determine the proportion of Resident Research Day projects that have progressed to publication.
    METHODS: Available internal records from 1998 to 2019 were used to identify presenters and projects. Academic productivity of presenters was estimated with the h-index from the Scopus database.
    RESULTS: One hundred forty-five students, residents, and fellows presented 276 projects at Resident Research Day from 1998 to 2019. These presentations were associated with 144 unique peer-reviewed publications, representing 52% of the presented projects. They were published an average of 1.8 years after presentation, and the presenter was the first or last author on 67% of them. The current average h-index of trainees who published at least 1 project (8.3) is significantly higher than the h-index of those who did not (5.0, P < 0.001).
    CONCLUSIONS: The James Barrett Brown Resident Research Day not only honors the legacy of Brown but also enhances scholarly activity of trainees. The opportunity to present and publish research teaches project planning, implementation, and data analysis, followed by manuscript preparation and the publication process. This important skill set can provide the foundation for the academic careers of future leaders in plastic surgery.

      Precision livestock farming (PLF) utilises information technology to continuously monitor and manage livestock in real-time, which can improve individual animal health, welfare, productivity and the environmental impact of animal husbandry, contributing to the economic, social and environmental sustainability of livestock farming. PLF has emerged as a pivotal area of multidisciplinary interest. In order to clarify the knowledge evolution and hotspot replacement of PLF research, based on the relevant data from the Web of Science database from 1973 to 2023, this study analyzed the main characteristics, research cores and hot topics of PLF research via CiteSpace. The results point to a significant increase in studies on PLF, with countries having advanced livestock farming systems in Europe and America publishing frequently and collaborating closely across borders. Universities in various countries have been leading the research, with Daniel Berckmans serving as the academic leader. Research primarily focuses on animal science, veterinary science, computer science, agricultural engineering, and environmental science. Current research hotspots center around precision dairy and cattle technology, intelligent systems, and animal behavior, with deep learning, accelerometer, automatic milking systems, lameness, estrus detection, and electronic identification being the main research directions, and deep learning and machine learning represent the forefront of current research. Research hot topics mainly include social science in PLF, the environmental impact of PLF, information technology in PLF, and animal welfare in PLF. Future research in PLF should prioritize inter-institutional and inter-scholar communication and cooperation, integration of multidisciplinary and multimethod research approaches, and utilization of deep learning and machine learning. Furthermore, social science issues should be given due attention in PLF, and the integration of intelligent technologies in animal management should be strengthened, with a focus on animal welfare and the environmental impact of animal husbandry, to promote its sustainable development.

      Mild cognitive impairment (MCI) is often considered a precursor to Alzheimer's disease (AD) and early diagnosis may help improve treatment effectiveness. To identify accurate MCI biomarkers, researchers have utilized various neuroscience techniques, with electroencephalography (EEG) being a popular choice due to its low cost and better temporal resolution. In this scoping review, we analyzed 2310 peer-reviewed articles on EEG and MCI between 2012 and 2022 to track the research progress in this field. Our data analysis involved co-occurrence analysis using VOSviewer and a Patterns, Advances, Gaps, Evidence of Practice, and Research Recommendations (PAGER) framework. We found that event-related potentials (ERP), EEG, epilepsy, quantitative EEG (QEEG), and EEG-based machine learning were the primary research themes. The study showed that ERP/EEG, QEEG, and EEG-based machine learning frameworks provide high-accuracy detection of seizure and MCI. These findings identify the main research themes in EEG and MCI and suggest promising avenues for future research in this field.

       Objective: The significant increase in the number of COVID-19 publications, on the one hand, and the strategic importance of this subject area for research and treatment systems in the health field, on the other hand, reveals the need for text-mining research more than ever. The main objective of the present paper is to discover country-based publications from international COVID-19 publications with text classification techniques.
    Methods: The present paper is applied research that has been performed using text-mining techniques such as clustering and text classification. The statistical population is all COVID-19 publications from PubMed Central® (PMC), extracted from November 2019 to June 2021. Latent Dirichlet allocation (LDA) was used for clustering, and support vector machine (SVM), scikit-learn library, and Python programming language were used for text classification. Text classification was applied to discover the consistency of Iranian and international topics.
    Results: The findings showed that seven topics were extracted using the LDA algorithm for international and Iranian publications on COVID-19. Moreover, the COVID-19 publications show the largest share in the subject area of "Social and Technology in COVID-19" at the international (April 2021) and national (February 2021) levels with 50.61% and 39.44%, respectively. The highest rate of publications at international and national levels was in April 2021 and February 2021, respectively.
    Conclusion: One of the most important results of this study was discovering a common trend and consistency of Iranian and international publications on COVID-19. Accordingly, in the topic category "Covid-19 Proteins: Vaccine and Antibody Response," Iranian publications have a common publishing and research trend with international ones.

       OBJECTIVE: To assess the time from completion to publication of randomized controlled trials (RCTs) on connective tissue diseases (CTDs), investigate the factors associated with, and explore the influence of significance of study results on time to publication (time-lag publication bias).
    METHODS: We included interventional, phase 2/3, 3, or 4 RCTs on CTDs registered in Clinicaltrials.gov from 2000 to 2016, whose results had been published in a peer-review journal less than 5 years after their completion. Main trial features, including the significance of primary outcome results, were collected. Time to publication was the time from study completion to the earliest publication date. Multivariable linear regression was used to identify factors associated with time to publication.
    RESULTS: We included 62 studies, mostly phase 3 (61%) trials on pharmacologic treatments (94%); we recruited patients with systemic lupus (55%) or systemic sclerosis (23%) and planned to enroll a median of 131 (IQR [interquartile range]: 61-288) patients. Twenty-two (35%) reported at least a statistically significant primary outcome. Median time to publication was 28 months (IQR: 17-36). In a multivariable analysis, time to publication progressively improved over time (faster publication in recent years, with the average time to publication decreasing by 1.3 [95% CI: 0.3-2.3] months per year) and was not influenced by the significance of primary outcome results, funder, impact factor of the journal, number of recruiting countries, and comparator.
    CONCLUSION: A high proportion of CTDs-RCTs is published beyond 2 years from completion. We did not find evidence of time-lag publication bias, and time to publication improved over time.

      This study examines how international agreements (especially the 1992 Rio Summit, the 1997 Kyoto Protocol, and the 2015 Paris Agreement) on climate change have fueled rampant economic literature worldwide. However, it has not been systematically classified or distinguished from the more traditional studies in this field. Hence, we use a scientometric analysis using four different approaches: natural language processing (NLP), citation analysis, co-citation network analysis, and content analysis. We conduct an ambitious Boolean search of 30 terms in Scopus and use NLP, along with unsupervised statistical learning techniques and content analysis to classify and analyze 2400 of the most relevant studies in this field. As such, independent results are complementary. We provide novel literature by mapping four major clusters: climate change corporate, climate finance, climate capitalism, and climate gateway belief.

       OBJECTIVE: We aimed to determine if there is an optimal time to complete dedicated research during surgical residency.
    BACKGROUND: Research is an integral part of academic general surgical residency, and dedicated research usually occurs after the 2nd or 3rd post-graduate year (PGY). The timing of dedicated research and its association with resident productivity, self-assessed competency (including technical skills), and fellowship match is not known.
    METHODS: PubMed was queried for publications resulting after dedicated research time for graduating surgical residents at a single institution from 2010 to 2021. Graduates were surveyed about their research experience and placed into 2 groups: research after PGY2 or PGY3.
    RESULTS: Sixty-six of 91 (73%) graduating residents completed dedicated research (after PGY2, n=28; after PGY3, n=38). Median number of total and first author publications was similar between groups; however, research after PGY2 was associated with an increased number of basic science publications by fellowship application deadlines (PGY2: 1.0[0-13] vs PGY3: 0.0[0-6], p=0.02). With a 79% survey response rate, there were no differences in self-assessed competencies upon return from research between cohorts. Most surveyed residents matched at their top fellowship choice (PGY2:70% vs PGY3:62%, p=0.77).
    CONCLUSIONS: Research after PGY2 or PGY3 had no association with residents' total number of publications, self-assessed competency, or rates of matching at first choice fellowship. As research after PGY2 had an increased number of basic science publications by time of fellowship application, surgical residents applying to fellowships that highly value basic science research may benefit from completing dedicated research after PGY2.

      The problem of identifying common concepts in the sciences and deciding when new ideas have emerged is an open one. Metascience researchers have sought to formalize principles underlying stages in the life cycle of scientific research, understand how knowledge is transferred between scientists and stakeholders, and explain how new ideas are generated and take hold. Here, we model the state of scientific knowledge immediately preceding new directions of research as a metastable state and the creation of new concepts as combinatorial innovation. Through a novel approach combining natural language clustering and citation graph analysis, we predict the evolution of ideas over time and thus connect a single scientific article to past and future concepts in a way that goes beyond traditional citation and reference connections.

      Bivalves are important members of the ecosystem and their populations are declining globally, making them a concern for their role in ecosystem services and the fishing industry. Bivalves are excellent bioindicators of MPs pollution due to their widespread distribution, filtering capabilities, and close association with human health. Microplastics (MPs) have direct and indirect impacts on bivalves, affecting their physiology, habitat structure, food sources, and persistence of organic pollutants. This review provides an extensive overview of the impact of MPs on bivalves, covering various aspects such as their economic significance, ecological roles, and importance in biomonitoring environmental quality. The article presents the current state of knowledge on the sources and pathways of MPs in aquatic environments and their effects on bivalves. The mechanisms underlying the effects of MPs on bivalves, including ingestion, filtration activity, feeding inhibition, accumulation, bioaccumulation, and reproduction, are also discussed. Additionally, a bibliometric analysis of research on MPs in bivalves is presented, highlighting the number of papers, geographical distribution, and keyword clusters relating to MPs. Finally, the review emphasizes the importance of ongoing research and the development of mitigation strategies to reduce the negative effects of MPs pollution on bivalves and their habitats in oceans and coastal waters.
