       OBJECTIVES: This study aims to analyze the publications that have studied top-cited articles in dentistry.
    MATERIAL AND METHODS: The study is applied research in terms of the purpose and scientometrics descriptive in terms of type, which has been done using the Retrospective Bibliometric Analysis. To retrieve the 100 most-cited studies in Scopus, an advance search was used. The search results indicate that 33 articles focused on analyzing the 100 most-cited publications on oral and dental subjects. The bibliographic information, including author, journal, country, institution, citation count, and citation density was analyzed. Then the full text of the articles was reviewed to identify the most productive journal, country, and institute in publishing the 100 most-cited articles and also article type, study design, level of evidence, and the most important subjects among the 100 most-cited papers.
    RESULTS: In these 33 articles, the topics of 3300 most-cited articles were introduced, as well as the introduction of the core journals, countries, and institutes in publishing top-cited articles. The most common research topics in the field of dentistry cover a range of dental public health and pediatric dentistry to adhesive restorative dentistry and implantology. Dental materials, oral medicine, and pathology seem like inseparable topics of common research in dentistry. J Dent Res, which was mentioned in nine articles, was introduced as the journal with the publication of articles of highest citation. J Clin Periodontol and Oral Surgery, Oral Medicine, Oral Pathology, and Oral Radiology were in the second place, being mentioned in five articles. The USA, and two institutions the University of Texas, and the University of Michigan are orderly core country and institute for the production of most-cited articles.
    CONCLUSION: Researchers and specialists can get familiar with the most productive author, journals, countries, and different institutes for publishing high-quality articles in the field of oral and dental subjects by the means of the results of this article. Furthermore, the results of this study ranked the most cited article topics, which are of interest for publication, demonstrating the future map road oral and dental research.

    Jian Zhou, Chen Dong, Qiuju Shu, Yang Chen, Qing Wang, Dandan Wang, Ge Ma.
      Increasing attention to skin regeneration has rapidly broadened research on the topic. However, no bibliometric analysis of the field's research trends has yet been conducted. In response to this research gap, this study analyzed the publication patterns and progress of skin regeneration research worldwide using a bibliometric analysis of 1,471 papers comprising 1,227 (83.4%) original articles and 244 (16.6%) reviews sourced from a Web of Science search. Publication distribution was analyzed by country/region, institution, journal, and author. The frequency of keywords was assessed to prepare a bibliometric map of the development trends in skin regeneration research. China and the United States were the most productive countries in the field: China had the greatest number of publications at 433 (29.4%) and the United States had the highest H-index ranking (59 with 15,373 citations or 31.9%). Author keywords were classified into four clusters: stem cell, biomaterial, tissue engineering, and wound dressing. "Stem cells," "chitosan," "tissue engineering," and "wound dressings" were the most frequent keywords in each cluster; therefore, they reflected the field's current focus areas. "Immunomodulation," "aloe vera," "extracellular vesicles," "injectable hydrogel," and "three-dimensional (3D) bioprinting" were relatively new keywords, indicating that biomaterials for skin regeneration and 3D bioprinting are promising research hotspots in the field. Moreover, clinical studies on new dressings and techniques to accelerate skin regeneration deserve more attention. By uncovering current and future research hotspots, this analysis offers insights that may be useful for both new and experienced scholars striving to expand research and innovation in the field of skin regeneration.

    Knowledge Mapping of Exosomes in Autoimmune Diseases: A Bibliometric Analysis (2002-2021).
    Fengping Wu, Jinfang Gao, Jie Kang, Xuexue Wang, Qing Niu, Jiaxi Liu, Liyun Zhang.
       Background: Autoimmune diseases (AIDs) are a class of chronic disabling diseases characterized by inflammation and damage to muscles, joints, bones, and internal organs. Recent studies have shown that much progress has been made in the research of exosomes in AIDs. However, there is no bibliometric analysis in this research field. This study aims to provide a comprehensive overview of the knowledge structure and research hotspots of exosomes in AIDs through bibliometrics.
    Method: Publications related to exosomes in AIDs from 2002 to 2021 were searched on the web of science core collection (WoSCC) database. VOSviewers, CiteSpace and R package "bibliometrix" were used to conduct this bibliometric analysis.
    Results: 312 articles from 48 countries led by China and the United States were included. The number of publications related to exosomes in AIDs is increasing year by year. Central South University, Sun Yat Sen University, Tianjin Medical University and University of Pennsylvania are the main research institutions. Frontiers in immunology is the most popular journal in this field, and Journal of Immunology is the most co-cited journal. These publications come from 473 authors among which Ilias Alevizos, Qianjin Lu, Wei Wei, Jim Xiang and Ming Zhao had published the most papers and Clotilde Théry was co-cited most often. Studying the mechanism of endogenous exosomes in the occurrence and development of AIDs and the therapeutic strategy of exogenous exosomes in AIDs are the main topics in this research field. "Mesenchymal stem cells", "microRNA", "biomarkers", "immunomodulation", and "therapy" are the primary keywords of emerging research hotspots.
    Conclusion: This is the first bibliometric study that comprehensively summarizes the research trends and developments of exosomes in AIDs. This information identifies recent research frontiers and hot directions, which will provide a reference for scholars studying exosomes.

    Ya-Fei Qin, Shao-Hua Ren, Bo Shao, Hong Qin, Hong-da Wang, Guang-Ming Li, Yang-Lin Zhu, Cheng-Lu Sun, Chuan Li, Jing-Yi Zhang, Hao Wang.
       Background: IL-37 is a recently identified cytokine with potent immunosuppressive functions. The research fronts of IL-37 are worth investigating, and there is no bibliometric analysis in this field. The purpose of this study is to construct the intellectual base and predict research hotspots of IL-37 research both quantitatively and qualitatively according to bibliometric analysis.
    Methods: The articles were downloaded from the Web of Science Core Collection (WoSCC) database from the inception of the database to 1 April 2022. CiteSpace 5.8.R3 (64-bit, Drexel University, Philadelphia, PA, USA) and Online Analysis Platform of Literature Metrology (https://bibliometric.com/) were used to perform bibliometric and knowledge-map analyses.
    Results: A total of 534 papers were included in 200 academic journals by 2,783 authors in 279 institutions from 50 countries/regions. The journal Cytokine published the most papers on IL-37, while Nature Immunology was the most co-cited journal. The publications belonged mainly to two categories of Immunology and Cell Biology. USA and China were the most productive countries. Meanwhile, the University of Colorado Denver in USA produced the highest number of publications followed by Radboud University Nijmegen in the Netherlands and Monash University in Australia. Charles A. Dinarello published the most papers, while Marcel F. Nold had the most co-citations. Top 10 co-citations on reviews, mechanisms, and diseases were regarded as the knowledge base. The keyword co-occurrence and co-citations of references revealed that the mechanisms and immune-related disorders were the main aspects of IL-37 research. Notably, the involvement of IL-37 in various disorders and the additional immunomodulatory mechanisms were two emerging hotspots in IL-37 research.
    Conclusions: The research on IL-37 was thoroughly reviewed using bibliometrics and knowledge-map analyses. The present study is a benefit for academics to master the dynamic evolution of IL-37 and point out the direction for future research.

    Gui-Fen Zhang, Wen-Xin Gong, Zheng-Yan-Ran Xu, Yi Guo.
       Background: Alzheimer's disease (AD) is one of the common neurodegenerative diseases, which often coexists with epilepsy. It is very significant to study the treatment options and the relationship between AD and epilepsy.
    Aims: The purpose of this study was to analyze the top 100 cited papers about AD and epilepsy using bibliometrics, and to describe the current situation and predict research hot spots.
    Methods: Top 100 papers were obtained from the Web of Science Core Collection (WoSCC). The WoSCC was used to analyze the author, institution, country, title, keywords, abstract, citation, subject category, publication year, impact factor (IF), and other functions. SPSS25 software was used for statistical analysis and CiteSpace V.5.7.R2 was used to visualize the information through collaborative networks.
    Results: The number of publications gradually increased from 2000 to 2021. The total citation count for the top 100 papers ranged from 15 to 433(mean = 67.43). The largest number of papers were published in 2016 (n = 11). Meanwhile, USA (centrality: 0.93) and Columbia University (centrality: 0.06) were the most influential research country and institutions, respectively. The top contributing journals was Journal of Alzheimer's Disease (8%). The IF for journals ranged from 1.819 to 53.44. A network analysis of the author's keywords showed that "beta" (centrality: 0.39), "amyloid beta" (centrality: 0.29), "hyperexcitability" (centrality: 0.29) and "disease" (centrality: 0.29) had a high degree of centrality.
    Conclusion: AD and epilepsy have been intensively studied in the past few years. The relationships, mechanisms and treatment of AD and epilepsy will be subjects of active research hotpots in future. These findings provide valuable information for clinicians and scientists to identify new perspectives with potential collaborators and cooperative countries.

    Does the journal impact factor predict individual article citation rate in otolaryngology journals?
    Salman Hussain, Abdullah Almansouri, Lojaine Allanqawi, Justine Philteos, Vincent Wu, Yvonne Chan.
       OBJECTIVE: Citation skew is a phenomenon that refers to the unequal citation distribution of articles in a journal. The objective of this study was to establish whether citation skew exists in Otolaryngology-Head and Neck Surgery (OHNS) journals and to elucidate whether journal impact factor (JIF) was an accurate indicator of citation rate of individual articles.
    METHODS: Journals in the field of OHNS were identified using Journal Citation Reports. After extraction of the number of citations in 2020 for all primary research articles and review articles published in 2018 and 2019, a detailed citation analysis was performed to determine citation distribution. The main outcome of this study was to establish whether citation skew exists within OHNS literature and whether JIF was an accurate prediction of individual article citation rate.
    RESULTS: Thirty-one OHNS journals were identified. Citation skew was prevalent across OHNS literature with 65% of publications achieving citation rates below the JIF. Furthermore, 48% of publications gathered either zero or one citation. The mean and median citations for review articles, 3.66 and 2, respectively, were higher than the mean and median number of citations for primary research articles, 1 and 2.35, respectively (P < .001). A statistically significant correlation was found between citation rate and JIF (r = 0.394, P = 0.028).
    CONCLUSIONS: The current results demonstrate a citation skew among OHNS journals, which is in keeping with findings from other surgical subspecialties. The majority of publications did not achieve citation rates equal to the JIF. Thus, the JIF should not be used to measure the quality of individual articles. Otolaryngologists should assess the quality of research through the use of other metrics, such as the evaluation of sound scientific methodology, and the relevance of the articles.

    Dyslipidemia research landscape and socioeconomic facilitators of scientific productivity in Southeast Asia.
    Maria Llaine J Callanta, Ourlad Alzeus G Tantengco.
       BACKGROUND: The growing prevalence of lipid disorder in Southeast Asia (SEA) resulted in an increase in clinical and epidemiological studies on dyslipidemia in the region. Thus, there is a need to summarize the existing evidence from the literature.
    AIMS: This paper determined the research landscape of dyslipidemia in SEA. This study also identified the socioeconomic facilitators of scientific productivity in dyslipidemia research in SEA.
    METHODS: A database search of dyslipidemia literature in SEA countries was performed using the Scopus database. Bibliographic information was obtained, and network visualization of collaboration among countries and keywords was created using VOSviewer software.
    RESULTS: This bibliometric analysis showed a continuous increase in published articles in SEA, most of which were from universities and hospitals in Thailand, Singapore, Malaysia, and Indonesia. The usual topics of dyslipidemia research in SEA include epidemiology, pathophysiology, comorbidities and complications, and treatment options for dyslipidemia. Research & development expenditure (total citations: p = 0.037; h-index: p = 0.031) and researchers in R&D (total citations: p = 0.005; h-index: p = 0.017) were positively correlated with citations and h-index for dyslipidemia publications from SEA countries. Moreover, the number of research collaborations within SEA and worldwide was positively correlated with the total publications, citations, and h-index of SEA countries for their dyslipidemia research outputs.
    CONCLUSION: In summary, this bibliometrics study showed an increasing trend of dyslipidemia research in SEA countries. Policymakers and administrators should invest more in dyslipidemia studies to propose better strategies in curbing the prevalence of this condition in SEA.

      (1) Background: The main basis for the public recognition of the merits of scientists has always been the system of scientific publications and citations. Our goal is to identify and analyze the most cited articles in the Public, Environmental & Occupational Health category. (2) Methods: We searched the Web of Science for all articles published in the "Public, Environmental & Occupational Health" category up to March 2022 and selected the 100 most cited articles. We recorded the number of citations, the journal, the year of publication, quartile, impact factor, institution, country, authors, topic, type of publication and collaborations. (3) Results: 926,665 documents were analyzed. The top 100 had 401,620 citations. The journal with the most articles was the Journal of Clinical Epidemiology and the one with the highest number of citations was Medical Care. The year with the highest number of articles in the top 100 was 1998. The country with the highest percentage of publications was the USA and the most productive institution was Harvard. The most frequent keywords were bias, quality, and extension. The largest collaboration node was between the USA, Canada, Germany, Spain, Australia, France, and Sweden. (4) Conclusions: This bibliometric study on Public, Environmental & Occupational Health provides valuable information not only to identify topics of interest in the analyzed category, but also to identify the differences in the topics they study.

    Seed Traits Research Is on the Rise: A Bibliometric Analysis from 1991-2020.
    Zhaogang Liu, Ming Zhao, Zhengkuan Lu, Hongxiang Zhang.
      Seed traits (ST) influence seedling establishment, population dynamics, community composition and ecosystem function and reflect the adaptability of plants and the environmental conditions they experienced. There has been a historical and global accumulation of studies on ST, but with few pertaining to visual and quantitative analyses. To understand the trends in the field of ST research in the past 30 years, we conducted a bibliometric analysis based on the Science Citation Index-Expanded (SCI-E) database. The analysis provided annual publications, time trends for keywords, the most productive journals, authors, institutions and countries, and a comprehensive overview of the ST field. Our results showed that in the past 30 years, the number of publications in ST research has increased at an average annual growth rate of 9.1%, while the average number of citations per paper per year showed a rapid increase-slow increase-decrease trend. Keyword analysis showed that "germination" was the most popular research section. Crop Science ranked first among the top journals and Theoretical and Applied Genetics had greater influence in this area and more citations than other journals. The 10 most productive institutions were mostly located in the United States, China and Australia. Furthermore, the three countries also had the largest number of publications and citations. Our analysis showed that the research interests in ST have evolved from genetics and agricultural science to ecological research over the last thirty years; as more fields embrace ST research, there are opportunities for international and interdisciplinary collaborations, cooperative institutions and new advances in the field.

    Fangwei Zhou, Tian Zhang, Ying Jin, Yifei Ma, Zhipeng Xian, Mengting Zeng, Guodong Yu.
       BACKGROUND AND OBJECTIVE: Research on allergic rhinitis (AR) immunotherapy has increased in recent decades. This study conducted a bibliometric and visualization analysis of studies related to AR immunotherapy to identify research trends and highlight current research foci.
    METHODS: Relevant original publications were obtained from the Science Citation Index-Expanded and Social Sciences Citation Index in the Web of Science Core Collection databases between 2002 and 2021. CiteSpace and VOSviewer software were used to identify and analyze the research foci and emerging trends in the field of AR immunotherapy.
    RESULTS: Over the last two decades, the number of publications related to AR immunotherapy has increased markedly. With regard to publications and access to collaborative networks, the leading country was the USA. Inspection of keyword bursts suggested that "subcutaneous immunotherapy", "quality of life", "prevalence", "rhino-conjunctivitis", and "mechanism" are emerging research hotspots. The timeline of the co-cited references cluster diagram revealed that the mechanism of allergen immunotherapy has emerged as a main topic in AR immunotherapy.
    CONCLUSION: Over the past 20 years, scholars have significantly improved their understanding of AR immunotherapy. The current research hotspots of AR immunotherapy in the health promotion domain lie in "subcutaneous immunotherapy", "quality of life", and "rhino-conjunctivitis". In addition, the mechanism of allergen immunotherapy has emerged as a frontier and focus of this field.

    Jun Hou, Hongjie Su, Xiaocong Kuang, Wencong Qin, Kaibing Liu, Kaixiang Pan, Bokai Zhang, Sijie Yang, Shenghui Yang, Xiao Peng, Xinyu Nie, Qikai Hua.
       Background: Osteoblasts-Osteoclasts has been a major area in bone disease research for a long time. However, there are few systematic studies in this field using bibliometric analysis. We aimed to perform a bibliometric analysis and visualization study to determine hotspots and trends of osteoblasts-osteoclasts in bone diseases, identify collaboration and influence among authors, countries, institutions, and journals, and assess the knowledge base to develop basic and clinical research in the future.
    Methods: We collected articles and reviews for osteoblasts-osteoclasts in bone diseases from the Web of Science Core Collection. In addition, we utilized scientometrics software (CiteSpace5.8 and VOSviewer1.6.18) for visual analysis of countries/regions, institutions, authors, references, and keywords in the field.
    Results: In total, 16,832 authors from 579 institutions in 73 countries/regions have published 3,490 papers in 928 academic journals. The literature in this field is rapidly increasing, with Bone publishing the most articles, whereas Journal of Bone and Mineral Research had the most co-cited journals. These two journals mainly focused on molecular biology and the clinical medicine domain. The countries with the highest number of publications were the US and China, and the University of Arkansas for Medical Sciences was the most active institution. Regarding authors, Stavros C. Manolagas published the most articles, and Hiroshi Takayanagi had the most co-cited papers. Research in this field mainly includes molecular expression and regulatory mechanisms, differentiation, osteoprotection, inflammation, and tumors. The latest research hotspots are oxidative stress, mutation, osteocyte formation and absorption, bone metabolism, tumor therapy, and in-depth mechanisms.
    Conclusion: We identified the research hotspots and development process of osteoblasts-osteoclasts in bone disease using bibliometric and visual methods. Osteoblasts-osteoclasts have attracted increasing attention in bone disease. This study will provide a valuable reference for researchers concerned with osteoblasts-osteoclasts in bone diseases.

    Global trends and hotspots in research on organoids between 2011 and 2020: a bibliometric analysis.
    Yufan Zhang, Panjing Yin, Ying Liu, Yiming Hu, Zhiqi Hu, Yong Miao.
       BACKGROUND: There is a lack of effective platforms that can rapidly screen drugs, for patients to achieve precision treatment. Since an organoid simulates the tissue or organ structure and function in vitro, it can be applied to predict the response to therapy, personalized medicine, and drug screening in clinical practice. However, the rapid development of this field meets several challenges. This study aimed to evaluate the current state of the organoid and prioritize future research areas using bibliometric analysis.
    METHODS: We selected articles and reviewers from the Web of Science database, using the search strategy syntax including "organoid" or "organoids", for the years 2011 to 2020. We conducted a general analysis and a thematic evolution analysis using the bibliometrix R package. Networks connecting productive countries/ regions/institutions/authors were generated using VOSviewer. We performed a co-occurrence analysis using VOSviewer, burstness analysis using Citespace, and co-word biclustering analysis and landform map using BICOMB and gCLUTO to identify possible current and future directions and hotspots.
    RESULTS: We selected 3,168 publications for our analysis. We found that the number of publications in this field has increased sharply. The greatest contributions to organoid research have been made by the United States (among countries) and the University of Michigan (among institutions), and Hans Clevers is the most influential author. The journals with the highest number of selected articles and citations are Cancer Research and Nature. We observed the possibility of keyword classification into five clusters. Their trend changed from "methods to build organoids" (e.g., "lgr5+ stem cell" and "3D culture") to "practical applications of organoids" (e.g., "cystic fibrosis" and "Zika virus").
    CONCLUSIONS: Our study used bibliometric analysis to provide an in-depth understanding of the trends and hotspots of organoid research. The primarily important subject matters are drug screening, disease modeling, personalized medicine, regenerative medicine, and developmental biology. However, this field still faces limitations in the form of lack of reproducibility, low levels of maturity and function, and the absence of appropriate readouts. Therefore, these five significant topics, and possible solutions to limitations (involving bioengineering strategies), might be noteworthy in the future.

    Tops and Trends in Iranian Cancer Research: A Bibliometric Analysis.
    Mozaffar CheshmehSohrabi, Rasoul Shabani, Shiva Shirdavani.
       BACKGROUND: Detecting the main actors and important topics of Iranian cancer research is essential for Iranian policymakers, clinicians, and researchers. This study was conducted to demonstrate the trends and tops in Iranian cancer research from 1960 to 2018.
    METHODS: A total of 22,370 Iranian cancer articles in Web of Science (WoS), PubMed, and Scopus, from 1960 through 2018, were extracted and preprocessed based on data mining techniques and analyzed using the collaboration network analysis, keywords analysis, and bibliometrics methods.
    RESULTS: The results reveal that, Tehran University of Medical Sciences (11.46%) among organizations, Asian Pacific Journal of Cancer Prevention (5%) among journals, Malekzadeh R (1.09%) among authors, and Breast cancer (10.37%) among topics ranked the first. The trend of Iranian cancer research represents three periods: 1) germinating period, from 1970 to 2000, 2) developing period, from 2002 to 2014, and 3) flourishing period, from 2014 to 2018. It is expected that this trend will continue. The results indicate an average 12.8% increase in the logarithm of the count of articles published by Iranian cancer researchers each year. The findings are contextualized with Price's publications trends principal for determining global and Iranian cancer research publication trends.
    CONCLUSION: The number of research papers published by Iranian researchers on cancer is increasing. In order to maintain the publication growth in this field, greater participation by other Iranian institutions is suggested. Although the quantity and quality of papers are increasing in some topics, certain topics and types of cancers should be still further studied and the Iranian policymakers should be encouraged to invest more in these topics.

    Qian Zhang, Jian Li, Ling Weng.
       Background: The characteristic symptom of coronavirus disease 2019 (COVID-19) is respiratory distress, but neurological symptoms are the most frequent extra-pulmonary symptoms. This study aims to explore the current status and hot topics of neurology-related research on COVID-19 using bibliometric analysis.
    Methods: Publications regarding neurology and COVID-19 were retrieved from the Web of Science Core Collection (WoSCC) on March 28 2022. The Advanced search was conducted using "TS = ('COVID 19' or 'Novel Coronavirus 2019' or 'Coronavirus disease 2019' or '2019-nCOV' or 'SARS-CoV-2' or 'coronavirus-2') and TS = ('neurology'or 'neurological' or 'nervous system' or 'neurodegenerative disease' or 'brain' or 'cerebra' or 'nerve')". Microsoft Excel 2010 and VOSviewer were used to characterize the largest contributors, including the authors, journals, institutions, and countries. The hot topics and knowledge network were analyzed by CiteSpace and VOSviewer.
    Results: A total of 5,329 publications between 2020 and 2022 were retrieved. The United States, Italy, and the United Kingdom were three key contributors to this field. Harvard Medical School, the Tehran University of Medical Sciences, and the UCL Queen Square Institute of Neurology were the major institutions with the largest publications. Josef Finsterer from the University of São Paulo (Austria) was the most prolific author. Tom Solomon from the University of Liverpool (UK) was the most cited author. Neurological Sciences and Frontiers in Neurology were the first two most productive journals, while Journal of Neurology held the first in terms of total citations and citations per publication. Cerebrovascular diseases, neurodegenerative diseases, encephalitis and encephalopathy, neuroimmune complications, neurological presentation in children, long COVID and mental health, and telemedicine were the central topics regarding the neurology-related research on COVID-19.
    Conclusion: Neurology-related research on COVID-19 has attracted considerable attention worldwide. Research topics shifted from "morality, autopsy, and telemedicine" in 2020 to various COVID-19-related neurological symptoms in 2021, such as "stroke," "Alzheimer's disease," "Parkinson's disease," "Guillain-Barre syndrome," "multiple sclerosis," "seizures in children," and "long COVID." "Applications of telemedicine in neurology during COVID-19 pandemic," "COVID-19-related neurological complications and mechanism," and "long COVID" require further study.

    Research trends in biodiversity loss: a bibliometric analysis.
    Yan-Ling Tan, Thian-Hee Yiew, Muzafar Shah Habibullah, Jen-Eem Chen, Siti Nuur-Ila Mat Kamal, Nur Adilah Saud.
      Although increased attempts to preserve biodiversity ecosystems have been widely publicized, bibliometric research of biodiversity loss remains limited. Using VOSviewer, we hope to provide a bibliometric assessment of global research trends on biodiversity loss from 1990 to 2021. Document type, language, publication trend, countries, institutions, Author Keywords, and Keywords Plus were all examined. This study recorded a total of 6599 publications from the Web of Science Core Collection database. According to the findings, biodiversity loss research is expected to rise dramatically in the near future. However, the role of social sciences and economics in biodiversity loss studies has received little attention. The USA made the most significant contribution in this field. Biological Conservation was the most productive journal, and Proceedings of the National Academy of Sciences of the United States of America was the most influential journal in biodiversity loss literature. Eisenhauer, N was the most prolific author, and Collen, B was the most referenced. Biodiversity, biodiversity loss mechanisms, biodiversity loss drivers, conservation, and climate change have been the topic of previous research. Possible future research hotspots may include species diversity and many elements of biodiversity. Lastly, the outcomes of this study suggest that existing socio-economic concerns can be integrated into decision-making processes to improve biodiversity conservation.

       AIM: To perform a 10-year scientometric analysis of the characteristics of the worldwide publication on the toxic effects of fluoride.
    MATERIALS AND METHODS: A bibliometric study of the worldwide scientific production on the toxic effects of fluoride during the years 2011-2020 was performed. All metadata from the Scopus database were evaluated. These were then exported to SciVal (Elsevier) for analysis of quantity, collaboration, and impact indicators.
    RESULTS: We found that the "Biological Trace Element Research" was the most productive journal with 22 published manuscripts and that the most productive universities on the systemic toxic effects of fluoride on the body were Shanxi Agricultural University, Guizhou Medical University, and Huazhong University of Science and Technology with 31, 11, and 10 manuscripts, respectively. In addition, it was found that most of the world scientific production on the toxic effects of fluoride was published in Q1 level journals (top 25%).
    CONCLUSION: Finally, it was concluded that most of the total production on this topic was published in high-impact Q1 journals, with China being the leading country in terms of number and impact of publications. Finally, there was evidence of collaboration between the United States, China, and India, being the countries that led in co-authorship by country.
    CLINICAL SIGNIFICANCE: This research is of clinical importance as it allows the identification of the most productive institutions, authors, and countries in this field. In this way, strategic alliances can be established to enhance the development of research.

    Development, hotspots and trend directions of groundwater salinization research in both coastal and inland areas: a bibliometric and visualization analysis from 1970 to 2021.
    Fan Yang, Chao Jia, Haitao Yang, Xiao Yang.
      As a global concern, the issue of groundwater salinization refers to the phenomenon of an increase in the overall chemical content over background levels in the groundwater. It involves a long-term process that could degrade groundwater quality and restrict its availability for drinking, irrigation and industry. For the effective protection and further research of groundwater resources, policy strongly depends on understanding the development, hotspots and trend directions of groundwater salinization research, which involves the degree, sources and processes of global groundwater salinization. However, such a comprehensive and systematic analysis has not been performed, and it is difficult to have a deeper understanding of groundwater salinization. The purpose of this paper is to analyze the knowledge structure, hot topics and trends in the field of groundwater salinization based on 6651 Web of Science (WoS) publications combined with CiteSpace for in-depth bibliometric and visual analysis. The results showed that 292 institutions in 125 countries have published articles in this field from 1970 to 2021. The USA was one of the most prolific contributors, with the largest number of publications and active institutions. Cooperation among authors has become frequent in recent years, and they tend to cooperate in groups. According to the analysis of co-occurrence keywords and co-cited articles, "water resources", "sea level rise" and "variable density flow" were identified as three hot topics. A keyword burst analysis revealed the emerging trends of concerns about global climate change and the sustainable utilization of water resources. In addition, the possible opportunities and challenges were explored that may be faced in groundwater salinization research. The outcomes of this study are significant for future research on groundwater management and pollution control.

    Author self-citations in the urology literature.
    Vaibhav Aggarwal.
       Objective: We aimed to determine the diachronous self-citation rate and the various article characteristics which can influence the rate and percentage of diachronous author self-citations using papers published in high-rank urology journals.
    Methods: We included all papers (N = 327 articles) published between January 2015 to April 2015 in the European Urology, The Journal of Urology and the BJU International. We determined author self-citations using the Scopus database and used negative binomial regression to determine which article characteristics affect self-citations.
    Results: 262 articles (80.2%) contained at least one self-citation.The mean number and percentage of author self-citations were 6.5 and 14.2 respectively. Adjusted analysis showed that the experimental/animal study design and the number of authors were significantly associated with both the number (IRR = 2.12, P = 0.011; IRR = 1.03, P = 0.002) and percentage of author self-citations (IRR = 2.95, P = 0.003; IRR = 1.03, P = 0.012). The number of citations in the Scopus and publication in European Urology were significantly associated with only the number of author self-citations.
    Conclusion: Diachronous author self-citation rate in urology is higher compared to general medical literature but similar to other surgical subspecialties. It may depend on the study design and the number of authors in the paper. For a more comprehensive evaluation, future studies should look at the context in which self-citations were made.

    Scientometric Review for Research Patterns on Additive Manufacturing of Lattice Structures.
    Chiemela Victor Amaechi, Emmanuel Folarin Adefuye, Irish Mpho Kgosiemang, Bo Huang, Ebube Charles Amaechi.
      Over the past 15 years, interest in additive manufacturing (AM) on lattice structures has significantly increased in producing 3D/4D objects. The purpose of this study is to gain a thorough grasp of the research pattern and the condition of the field's research today as well as identify obstacles towards future research. To accomplish the purpose, this work undertakes a scientometric analysis of the international research conducted on additive manufacturing for lattice structure materials published from 2002 to 2022. A total of 1290 journal articles from the Web of Science (WoS) database and 1766 journal articles from the Scopus database were found using a search system. This paper applied scientometric science, which is based on bibliometric analysis. The data were subjected to a scientometric study, which looked at the number of publications, authorship, regions by countries, keyword co-occurrence, literature coupling, and scientometric mapping. VOSviewer was used to establish research patterns, visualize maps, and identify transcendental issues. Thus, the quantitative determination of the primary research framework, papers, and themes of this research field was possible. In order to shed light on current developments in additive manufacturing for lattice structures, an extensive systematic study is provided. The scientometric analysis revealed a strong bias towards researching AM on lattice structures but little concentration on technologies that emerge from it. It also outlined its unmet research needs, which can benefit both the industry and academia. This review makes a prediction for the future, with contributions by educating researchers, manufacturers, and other experts on the current state of AM for lattice structures.

    Shuang Wang, Liang Zheng, Jun-Xiong Ma, Hong Wang, Shao-Tong Sun, Bo-Hua Zhang, Xin-Lei Guo, Liang-Bi Xiang, Yu Chen.
      This study aimed to analyze the most influential publications on vertebral augmentation for treating osteoporotic vertebral compression fracture. The Web of Science database was searched using the key words "percutaneous vertebroplasty," "percutaneous kyphoplasty," "balloon kyphoplasty," "vertebroplasty," "kyphoplasty," and "vertebral augmentation." The top 100 publications were arranged by citations per year and descriptively and visually analyzed. The top 100 publications were cited 25,482 times, with an average of 14.4 citations per paper per year. The corresponding authors of the publications represented 17 nations, with most authors being American (46 authors). Thirty-two journals were involved, with SPINE issuing the most publications (24 papers of the 100). Clinical research (73 of the 100 papers) outnumbered basic studies (14 papers) and systematic reviews (13 papers), and the most publications were published between 2000 and 2004. Co-citation analysis of the key words indicated that the top 5 focus areas were "complication," "balloon kyphoplasty," "vertebral compression fracture," "biomechanics," and "calcium phosphate cement." The top 3 keywords with the strongest citation bursts were "compression fracture," "cement," and "balloon kyphoplasty." The keywords with persistent strong citation bursts are "balloon kyphoplasty" and "augmentation." There are still contrary opinions about vertebral augmentation; new research should be conducted with more deliberate design and longer follow-up.

    Zhexin Ni, Sheng Wang, Yangshuo Li, Ling Zhou, Dongxia Zhai, Demeng Xia, Chaoqin Yu.
       Background: Gut microbiota is a complex ecosystem that is vital for the development and function of the immune system, is closely associated with host immunity, and affects human health and disease. Therefore, the current progress and trends in this field must be explored.
    Purpose: No bibliometric analysis has been conducted on gut microbiota and host immune response. This study aimed to analyze the current progress and developing trends in this field through bibliometric and visual analysis.
    Methods: Global publications on gut microbiota and host immune response from January 2011 to December 2021 were extracted from the Web of Science (WOS) collection database. GraphPad Prism, VOSviewer software, and CiteSpace were employed to perform a bibliometric and visual study.
    Results: The number of publications has rapidly increased in the last decade but has declined in the most recent year. The Cooperation network shows that the United States, Harvard Medical School, and Frontiers in Immunology were the most active country, institute, and journal in this field, respectively. Co-occurrence analysis divided all keywords into four clusters: people, animals, cells, and diseases. The latest keyword within all clusters was "COVID," and the most frequently occurring keyword was "SCFA."
    Conclusion: Gut microbiota and host immune response remain a research hotspot, and their relation to cancer, CNS disorders, and autoimmune disease has been explored. However, additional studies on gut microbiota must be performed, particularly its association with bacterial strain screening and personalized therapy.

    Huai-Yu Yang, Dan Wang, Xi Lin, Chao Han, Yan-Wei Lv, Ren-Qian Huang, Jie Zhang, Zhao-Shen Li, Zhuan Liao, Liang-Hao Hu.
       PURPOSE: Endoscopic retrograde cholangiopancreatography (ERCP) has been used in clinical practice for over 50 years. This study aims to investigate the current state of research in the field of ERCP.
    METHODS: Web of Science database was searched using the term "ERCP" for articles published between 1994 and 2018. The total number of articles from the top 20 countries with the most published articles was determined. The top 5 countries were compared in terms of output per capita, number of articles published in top journals, cumulative impact factor (IF), and average IF. All annual data were subjected to time-trend analysis. The frequently used terms in the titles and abstracts of all articles were retrieved to conduct co-occurrence analysis to determine the research focus of ERCP.
    RESULTS: A total of 9960 articles on ERCP were published between 1994 and 2018, of which 8778 articles were from the top 20 producing countries. There was a significant positive correlation between the output and GDP of each country (R = 0.870, P = .001). The United States of America (USA), Japan, Germany, Italy, and China were the top 5 producing countries with 3190 (32.0%), 868 (8.7%), 658 (6.6%), 512 (5.1%) and 488 (4.9%) articles published, respectively. The USA, Japan, Italy, and China were trending upwards in the total outputs and outputs per capita, while Germany were trending downwards. For average IF, Germany had a downwards trend, while the other 4 countries remained stable. Overall, the USA had the highest output per capita (97.5/10 million) and the highest average IF (6.454). China had the lowest output per capita (3.5/10 million) and average IF (3.125). The ERCP procedures for sphincter of Oddi dysfunction, the combination of ERCP, and laparoscopic cholecystectomy have been the research focus of ERCP.
    CONCLUSIONS: Except for Germany, research on ERCP will continue to increase in the top-producing countries. The outputs per capita and quality of articles from developed countries are higher than those from developing countries.

    The Intellectual Structure of Research on Rural-to-Urban Migrants: A Bibliometric Analysis.
    Huichen Gao, Shijuan Wang.
      As noted in the United Nations' Sustainable Development Goals 2030 agenda, sustainable cities "without leaving anyone behind" should take into consideration migrant groups, which may play only a marginal role but may be at the root of potential social conflicts. This study thereby promotes cross-disciplinary explorations of knowing and understanding the rural-to-urban internal migrants against the background of rapid urbanization. This study conducted a bibliometric analysis based on 2788 English language articles obtained from the Web of Science Core Collection database. As China's unique Hukou system highlights the divide between rural migrants and urban dwellers, migrant studies have extended to a diverse range of interests. We underlined the most productive sources and authors in this area and identified networks of collaboration among countries and institutions. Furthermore, we found trends in research themes and topics and research clusters through keyword-based analysis techniques. The results provide a rich source of information on the intellectual structure of the chosen domain of rural-to-urban migrants.

    The Russian demography in 2010-2020: scientometric analysis according Elsevier data.
    T K Rostovskaya, A P Bagirova, P I Ananchenkova.
      The actuality of demographic research is permanently at high level both in Russia and in the world. The purpose of the study is to establish placement of studies and researchers in Russia on the world map of demographic science. The scientometric analysis was applied to the base of international quoting Scopus (Elsevier). The analysis of universe of discourse "Demography" was implemented using SciVal (Elsevier) on the basis of number of publications, number of viewing abstracts or full texts of publications, number of quoting, weighted-average impact-factor of journals. To compare trends according number of publications and quoting in the universe of discourse eLibrary data was used. The results of analysis demonstrated significant lagging of Russian publication activity on demography from countries-leaders on scientometric indices. At that, increased interest to Russian scientific results was established at the level of publications viewing. The most notable place in research of prominent topics in demography the Russian researchers assign to problematics of natality and inner migration. The number of directions targeting to ameliorate considered situation and to place the results of Russian demographic studies on world map of demographic science was proposed.

    Emerging trends in sacubitril/valsartan research: A bibliometric analysis of the years 1995-2021.
    Ping Lai, Jin-Hua Xue, Mu-Jin Xie, Jin-Hua Ye, Ke-Jun Tian, Jia-Yuan Ling, Wen-Ting Zhong, Dong Chen, Yi-Ming Zhong, Yong-Ling Liao.
       BACKGROUND: Sacubitril/valsartan has been approved for the treatment of heart failure (HF) patients with reduced ejection fraction; since then, it gradually became a new star drug in the therapy of HF. Nevertheless, the effectiveness of sacubitril/valsartan remains under investigation. Thus far, only a few bibliometric studies have systematically analyzed the application of sacubitril/valsartan.
    METHODS: Publications on sacubitril/valsartan were retrieved from the Web of Science Core Collection on April 29, 2021. Data were analyzed using Microsoft Excel 2019 (Redmond, WA), VOS viewer (Redmond, WA), and Cite Space V (Drexel University, Philadelphia, PA).
    RESULTS: A total of 1309 publications on sacubitril/valsartan published from 1995 to 2021 were retrieved. The number of publications regarding sacubitril/valsartan increased sharply in the last 6 years (2015-2021), and American scholars authored >40% of those publications. Most were published in the European Journal of Heart Failure, the United States was the bellwether with a solid academic reputation in this area. Solomon published the highest number of related articles and was the most frequently cited author. "Heart failure" was the leading research hotspot. The keywords, "inflammation," "fibrosis," and "oxidative stress" appeared most recently as research fronts.
    CONCLUSIONS: Research attention should be focused on clinical trial outcomes. Considering its effectiveness in HF, the mechanisms and further applications of sacubitril/valsartan may become research hotspots in the future and should be closely examined.

    Sushma Dhital, Dipesh Rupakheti, Maheswar Rupakheti, Xiufeng Yin, Yanli Liu, Joy James Mafiana, Mohammed Muneer Alareqi, Halabia Mohamednour, Benzhong Zhang.
      Indoor air pollution (IAP) is one of the leading risk factors for various adverse health outcomes including premature deaths globally. Even though research related to IAP has been carried out, bibliometric studies with particular emphasis on this topic have been lacking. Here, we investigated IAP research from 1990 to 2019 retrieved from the Web of Science database through a comprehensive and systematic scientometric analysis using the CiteSpace 5.7.R2, a powerful tool for visualizing structural, temporal patterns and trends of a scientific field. There was an exponential increase in publications, however, with a stark difference between developed and developing countries. The journals publishing IAP related research had multiple disciplines; 'Indoor Air' journal that focuses solely on IAP issues ranked fifth among top-cited journals. The terms like 'global burden', 'comparative risk assessment,' 'household air pollution (HAP)', 'ventilation', 'respiratory health', 'emission factor', 'impact,' 'energy', 'household', 'India' were the current topical subject where author Kirk R. Smith was identified with a significant contribution. Research related to rural, fossil-fuel toxicity, IAP, and exposure-assessment had the highest citation burst signifying the particular attention of scientific communities to these subjects. Overall, this study examined the evolution of IAP research, identified the gaps and provided future research directions.

    Mapping the field of bioenergy with carbon capture and storage (BECCS): scientific cooperation and co-citation analyses.
    Meihui Li, Xinxin Xu.
      Bioenergy with carbon capture and storage (BECCS), as the most scalable negative emission technology, can limit global warming to 1.5 ℃ under climate change scenarios. With increasing research on BECCS, concerns have been raised about its deployment and impacts. In view of the limited research on the possible structure and collaboration in the field of BECCS, this study sought to determine the scientific cooperation and knowledge structure using bibliometric approaches based on a science mapping analysis. Co-authorship and co-citation networks were developed from CiteSpace to explore the individual, institutional, and national collaborations, and detect the knowledge structure in the field of BECCS. Six key research groups with connections were found with the research group centered on NIALL MAC DOWELL and PETE SMITH being more focused on BECCS. Cluster analysis results show that the knowledge structure of BECCS has gradually formed. The research field has been continuously developed and relatively independent. The findings provide researchers with an in-depth understanding of the current state of BECCS research and its knowledge structure.

    Yan Liu, Linlin Ding, Yunyan Xianyu, Shuke Nie, Jiying Yang.
       BACKGROUND: The diagnosis and treatment rate of Parkinson disease (PD) with depression has a low diagnostic rate, and there is no consensus on the choice of treatment mode. This study evaluates the global research trends of scientific outputs related to depression in PD from multiple perspectives, using a bibliometric analysis and visualization tool to scientifically analyze the knowledge from the literature.
    METHODS: Literature related to depression in PD published from 2012 to 2021 was included and selected from the Web of Science Core Collection database in October 2021. CiteSpace software was used to visualize and analyze co-occurrence analyses for countries, institutions, authors, and keywords.
    RESULTS: A total of 4533 articles from the Web of Science database were included. The United States made the largest contribution with the majority of publications (1215; 29.40%). Toronto University was the most productive institution. PD, depression, quality of life, dementia, nonmotor symptom, prevalence, anxiety, Alzheimer disease, symptom, and disorder would be significantly correlated with depression in PD. The current hot spots in this field focus on the following: risk factors for depression in PD, assessment scale of depression in PD, and rehabilitation of depression in PD.
    CONCLUSIONS: This analysis not only reveals the current research trends and hotspots but also provides some instructive suggestions on the development of depression in PD.

    Mental Health Research During the COVID-19 Pandemic: Focuses and Trends.
    Yaodong Liang, Li Sun, Xin Tan.
       Background: The COVID-19 pandemic has profoundly influenced the world. In wave after wave, many countries suffered from the pandemic, which caused social instability, hindered global growth, and harmed mental health. Although research has been published on various mental health issues during the pandemic, some profound effects on mental health are difficult to observe and study thoroughly in the short term. The impact of the pandemic on mental health is still at a nascent stage of research. Based on the existing literature, we used bibliometric tools to conduct an overall analysis of mental health research during the COVID-19 pandemic.
    Method: Researchers from universities, hospitals, communities, and medical institutions around the world used questionnaire surveys, telephone-based surveys, online surveys, cross-sectional surveys, systematic reviews and meta-analyses, and systematic umbrella reviews as their research methods. Papers from the three academic databases, Web of Science (WOS), ProQuest Academic Database (ProQuest), and China National Knowledge Infrastructure (CNKI), were included. Their previous research results were systematically collected, sorted, and translated and CiteSpace 5.1 and VOSviewers 1.6.13 were used to conduct a bibliometric analysis of them.
    Result: Authors with papers in this field are generally from the USA, the People's Republic of China, the UK, South Korea, Singapore, and Australia. Huazhong University of Science and Technology, Hong Kong Polytechnic University, and Shanghai Jiao Tong University are the top three institutions in terms of the production of research papers on the subject. The University of Toronto, Columbia University, and the University of Melbourne played an important role in the research of mental health problems during the COVID-19 pandemic. The numbers of related research papers in the USA and China are significantly larger than those in the other countries, while co-occurrence centrality indexes in Germany, Italy, England, and Canada may be higher.
    Conclusion: We found that the most mentioned keywords in the study of mental health research during the COVID-19 pandemic can be divided into three categories: keywords that represent specific groups of people, that describe influences and symptoms, and that are related to public health policies. The most-cited issues were about medical staff, isolation, psychological symptoms, telehealth, social media, and loneliness. Protection of the youth and health workers and telemedicine research are expected to gain importance in the future.

    A bibliometric analysis of research on (R)-ketamine from 2002 to 2021.
    Teng He, Di Wang, Zifeng Wu, Chaoli Huang, Xiangyang Xu, Xiangqing Xu, Cunming Liu, Kenji Hashimoto, Chun Yang.
      Anesthetic ketamine is a racemic mixture containing equal amount of (R)-ketamine and (S)-ketamine. Increasing preclinical data show that (R)-ketamine has a rapid-onset and sustained antidepressant without significant side effects. There are currently many studies on (R)-ketamine, however, the quantity and quality of these studies are unknown. Therefore, we conducted a bibliometric analysis of research on (R)-ketamine from January 2002 to December 2021. We obtained the publications on (R)-ketamine from the Web of Science database during the period. A variety of bibliographic elements were collected, including annual publications, authors, countries/regions, institutions, journals, and keywords. A total of 922 publications were included in this study. Professor Kenji Hashimoto of Chiba University in Japan was the most productively influential author in the field of (R)-ketamine and the authors from United States were the leader in this field. In addition, we found that the antidepressant effect of (R)-ketamine has been a hotspot in very recent years. This study provided a comprehensive analysis of research on (R)-ketamine and highlighted the growing interest in (R)-ketamine and its antidepressant effects.

    Knowledge mapping of planetary boundaries based on bibliometrics analysis.
    Siying Chen, Demin Chen, Zhixiong Tan, Maozhi Chen, Jingwei Han.
      The planetary boundaries concept has triggered a vast amount of pure and applied scientific research, as well as policy and governance activities globally. Indeed, it has rapidly become a centerpiece of sustainability study. It is crucial to review the scientific state of the planetary boundaries (PB) concept systematically. However, there is a lack of research on drawing a scientific investigation map of planetary boundaries. Therefore, to clarify the spatial and temporal distribution characteristics, research hotspots, and frontiers of planetary boundaries, a scientometric analysis was performed based on 530 academic publications on planetary boundaries from 2009 to 2021. This paper conducted the analysis by visualizing the social network, dual-map overlay, co-cited references, structure variation article, and co-occurrence keywords with CiteSpace. The results show that as a new achievement and paradigm in sustainable development research, the planetary boundaries framework is gradually getting global attention and promotion, which has increasingly become an interdisciplinary hot research topic. The most productive authors and institutions are concentrated in England, the USA, Germany, and Sweden. Relevant articles were mainly published in journals focusing on ecology, earth, marine, veterinary, animal, economics, and politics. In addition, we summarized four predominant research themes by clustering keywords: the calculation of single boundary threshold and present value, the integration with assessment methods such as life cycle assessment and footprint families, the downscaling of planetary boundaries, and the expansion to economic and social domains. For scholars who are interested in this topic, this paper would be a useful reference and guideline.

    A systematic assessment of research trends on polycyclic aromatic hydrocarbons in different environmental compartments using bibliometric parameters.
    Abiodun O Adeniji, Kunle Okaiyeto, Mosotho J George, Emmanuel B Tanor, Lucy Semerjian, Anthony I Okoh.
      Polycyclic aromatic hydrocarbons (PAHs) are a large group of diverse hazardous organic compounds that are relatively stable and widely distributed throughout the world's ecosystems due to various anthropogenic activities. They are generally less soluble in water and have a low vapour pressure, but dissolve easily in adipose tissues; and they bioaccumulate into high concentrations in aquatic animals, thereby exerting a variety of hazardous and lethal effects. Despite the plethora of research studies on these pollutants, only few bibliometric reviews on the subject have been documented in the literature. As a result, the present study aimed to assess the research growth on PAHs-related studies across different ecosystems. Science Citation Index-Expanded of Web of Science was explored to obtain the research studies that were conducted between 1991 and 2020, and RStudio was utilized for the data analysis. Annual productivity increased arithmetically over the years, with a 9.2% annual growth rate and a collaboration index of 2.52. Foremost among the trend topics in this field of study include soil, sediments, biodegradation, bioremediation, bioavailability, and source apportionment. China, USA, Spain, France and Germany were the five top-ranked countries in terms of publications and citations over the three decades investigated; however, Korea, Japan, United Kingdom, Germany, and Canada were ranked as the five leading countries in terms of collaboration per published article (MCP ratio). Therefore, efforts to strengthen international collaboration in this field of study especially among the less participating countries and continents are thus encouraged. The findings of this study are expected to provide future direction for the upcoming researchers in identifying the hot spots in this field of study as well as research leaders whom to seek collaboration in their future research plan.

    Exploring the past, present, and future of the mindfulness field: A multitechnique bibliometric review.
    Aldijana Bunjak, Matej Černe, Emilie Lara Schölly.
      This paper provides an overview of the mindfulness literature up until the end of 2020 by (a) uncovering its underlying intellectual structure, (b) identifying the most influential and popular themes, and (c) presenting new directions for future research on mindfulness. To this end, a systematic quantitative review based on bibliometric methods was conducted, which is perhaps less prone to researcher bias and can complement existing meta-analyses and qualitative (narrative) structured reviews as an objective approach. Three bibliometric techniques-document co-citation analysis, co-word (co-occurrence and content) analysis, and bibliographic coupling-were applied to explore the past, present, and future of mindfulness research. The co-citation analysis showed that measurement, mechanisms, mindfulness-based interventions, and examinations of the efficacy of mindfulness interventions are among the key theoretical knowledge bases from which the field of mindfulness is derived. The content analysis demonstrated the beneficial effects of mindfulness meditation for physical and mental health conditions. The bibliographic coupling revealed novel directions in cognitive behavioral therapy, emotion regulation, the application of mindfulness practice to children and adolescents, mindfulness at work, and the role of mindfulness in positive psychology. The large sample of articles that was analyzed allowed us to provide a broader and more objective overview than possible with other forms of literature reviews. The combination of the three bibliometric techniques granted deeper insights into the complex multidisciplinary field of mindfulness, along with specific suggestions for future research.

    Bibliometric and visual analysis of research on nutcracker syndrome from 1974 to 2021: A systematic review.
    Yuchang Jiang, Zaili Gan, Qinsheng Wang, Yang Chen, Yong Jiang.
       BACKGROUND: At present, researchers have obtained fruitful results in the study of nutcracker syndrome (NCS), but there is still a lack of systematic research on the overall status of this disease. This article aims to describe the past and current status of research into NCS, and predict future research trends and popular research topics.
    METHODS: Using bibliometric and visualization methods, 552 articles related to NCS collected from the Scopus database from 1974 to 2021 were analyzed from multiple perspectives.
    RESULTS: Overall, the amount of literature related to NCS is on the rise every year, and the number of citations is the turning point in 2006. The United States has the largest number of publications and has the most extensive cooperation with other countries. The main contents of the co-authored study focused on the symptoms, surgical procedures, and concomitant diseases of NCS. Keywords such as peak velocity, ultrasonography, orthostatic proteinuria, etc appeared earlier, whereas diagnosis, chronic pelvic pain, endovascular stents, etc appeared later.
    CONCLUSIONS: The literature utilization rate of NCS is relatively insufficient. The pathogenesis and pathological mechanisms need to be further studied, and the diagnostic criteria and surgical methods will continue to be favored by clinicians.

    Khalid Mehmood, Yansong Bao, Sana Mushtaq, Saifullah, Muhammad Ajmal Khan, Nadeem Siddique, Muhammad Bilal, Zhang Heng, Li Huan, Muhammad Tariq, Sibtain Ahmad.
      As scientific technology and space science progress, remote sensing has emerged as an innovative solution to ease the challenges of the COVID-19 pandemic. To examine the research characteristics and growth trends in using remote sensing for monitoring and managing the COVID-19 research, a bibliometric analysis was conducted on the scientific documents appearing in the Scopus database. A total of 1,509 documents on this study topic were indexed between 2020 and 2022, covering 165 countries, 577 journals, 5239 institutions, and 8,616 authors. The studies related to remote sensing and COVID-19 have a significant increase of 30% with 464 articles. The United States (429 articles, 28.42% of the global output), China (295 articles, 19.54% of the global output), and the United Kingdom (174 articles, 11.53%) appeared as the top three most contributions to the literature related to remote sensing and COVID-19 research. Sustainability, Science of the Total Environment, and International Journal of Environmental Research and Public Health were the three most productive journals in this research field. The utmost predominant themes were COVID-19, remote sensing, spatial analysis, coronavirus, lockdown, and air pollution. The expansion of these topics appears to be associated with cross-sectional research on remote sensing, evidence-based tools, satellite mapping, and geographic information systems (GIS). Global pandemic risks will be monitored and managed much more effectively in the coming years with the use of remote sensing technology.

    The relationship between academic influence, NIH funding, and industry payments among academic shoulder and elbow surgeons.
    Brett D Haislup, Sarah Trent, Sean Sequeira, Anand M Murthi, Melissa A Wright.
       BACKGROUND: The effect of academic influence, or the volume and quality of a surgeon's publications, on industry payments and National Institutes of Health (NIH) funding has recently been studied in some academic orthopedic subspecialities. The purpose of this study is to evaluate the relationship between academic influence, industry payments, and NIH funding among American Shoulder and Elbow Surgeons (ASES) accredited shoulder and elbow fellowship faculty.
    METHODS: Shoulder and elbow fellowships and affiliated faculty members were identified from the ASES website. Academic influence, measured by Hirsch (h)-index, and number of articles published were determined for faculty members using the Scopus Database Author Identifier tool. Industry payments were derived from the CMS Open Payments Database. NIH funding was determined using The National Institutes of Health's Research Portfolio Online Reporting Tool (RePORT). Statistical analysis used Spearman correlations and the Mann-Whitney U test with an alpha value of 0.05 (p < 0.05).
    RESULTS: 146 faculty members were included. Twenty two percent (42/146) received non-research payments, while 78% (114/146) received industry research funding averaging $6,364 (SD= $21,213). NIH funding averaged $272,589 (SD= $224,635) and 5% received NIH funding (7/146). Faculty members who received NIH funding had a higher average h-index than those who did not (38 ± 22 vs. 22.64 ± 22.7 p=0.02), while those receiving industry research payments had a greater number of publications than those who did not (127.97 ± 127.2 vs 100.3 ± 122.3, p=.03). Industry non-research payments did not impact number of publications or h-index.
    DISCUSSION/CONCLUSION: This study demonstrated that academic influence among academic shoulder and elbow surgeons is not greater in those who receive non-research industry funding. However, surgeons with industry research funding did produce more publications, while NIH funding is associated with greater academic influence.

    The Clinical Research Bias Index (CRBI): A novel journal ranking method applied to child health respiratory studies.
    Manishaa Vairavan, Andrew Prayle, Patrick Davies.
       Background and Aims: Journal impact factor has historically been taken as a proxy for quality. However, this is open to significant manipulation and bias. There is currently not widely adopted, robust journal and paper ranking metric which is focused solely on risk of bias.
    Methods: Risk of bias data was extracted from all Cochrane database systematic reviews in Child Health, Lungs, and Airways for the years 2017-2019. A novel paper quality score, the Clinical Research Bias Index (CRBI), was applied. Individual paper data were pooled for each journal. A comparison was made to journal impact factors, individual paper citations, reads, and altmetric scores.
    Results: 927 papers were analyzed for risk of bias. 119 (12·8%) scored a CRBI of 100%, with a mean score of 70%. A journal's overall CRBI risk of bias score was poorly correlated with impact factor (r 0.25). Citations (r 0.02), and reads (r 0.01) of individual papers showed very little association with the paper's risk of bias. Likewise, reads were not correlated with citations (r 0.03). H-index and Altmetric scores were similarly poorly correlated with CRBI.
    Conclusion: The novel research quality tool CRBI demonstrates the poor correlation between journal impact factor, citations, and risk of bias. Journal and paper ranking metrics should ensure that they are fit for purpose, and enable the dissemination of high-quality research for the benefit of patients. We propose the CRBI as a potential solution which is resistant to manipulation and will reward the creation and publication of bias-free research.

    Trends of research productivity across author gender and research fields: A multidisciplinary and multi-country observational study.
    Milad Haghani, Alireza Abbasi, Clara C Zwack, Zahra Shahhoseini, Nick Haslam.
      Bibliographic properties of more than 75 million scholarly articles, are examined and trends in overall research productivity are analysed as a function of research field (over the period of 1970-2020) and author gender (over the period of 2006-2020). Potential disruptive effects of the Covid-19 pandemic are also investigated. Over the last decade (2010-2020), the annual number of publications have invariably increased every year with the largest relative increase in a single year happening in 2019 (more than 6% relative growth). But this momentum was interrupted in 2020. Trends show that Environmental Sciences and Engineering Environmental have been the fastest growing research fields. The disruption in patterns of scholarly publication due to the Covid-19 pandemic was unevenly distributed across fields, with Computer Science, Engineering and Social Science enduring the most notable declines. The overall trends of male and female productivity indicate that, in terms of absolute number of publications, the gender gap does not seem to be closing in any country. The trends in absolute gap between male and female authors is either parallel (e.g., Canada, Australia, England, USA) or widening (e.g., majority of countries, particularly Middle Eastern countries). In terms of the ratio of female to male productivity, however, the gap is narrowing almost invariably, though at markedly different rates across countries. While some countries are nearing a ratio of .7 and are well on track for a 0.9 female to male productivity ratio, our estimates show that certain countries (particularly across the Middle East) will not reach such targets within the next 100 years. Without interventional policies, a significant gap will continue to exist in such countries. The decrease or increase in research productivity during the first year of the pandemic, in contrast to trends established before 2020, was generally parallel for male and female authors. There has been no substantial gender difference in the disruption due to the pandemic. However, opposite trends were found in a few cases. It was observed that, in some countries (e.g., The Netherlands, The United States and Germany), male productivity has been more negatively affected by the pandemic. Overall, female research productivity seems to have been more resilient to the disruptive effect of Covid-19 pandemic, although the momentum of female researchers has been negatively affected in a comparable manner to that of males.

    Language and Geographic Representation of Neurosurgical Journals: A Meta-Science Study.
    Nathan A Shlobin, Maria Punchak, Andre E Boyke, Molly Beestrum, Karen Gutzman, Gail Rosseau.
       OBJECTIVE: Medical journals have a role in promoting representation of neurosurgeons who speak primary languages other than English. We sought to characterize the language of publication and geographic origin of neurosurgical journals, delineate associations between impact factor (IF) and language and geographic variables, and describe steps to overcome language barriers to publishing.
    METHODS: Web of Science, Scopus, and Ulrich's Serial Analysis system were searched for neurosurgery journals. Journals were screened for relevance. Language of publication, country and World Health Organization region, World Bank income status and Gross Domestic Product (GDP), and citation metrics were extracted.
    RESULTS: Of 867 journals, 74 neurosurgical journals were included. Common publication languages were English (52, 70.3%), Mandarin (5, 6.8%), and Spanish (4, 5.4%). Countries of publication for the greatest number of journals were the United States (23, 31.1%), United Kingdom (8, 10.8%), and China (6, 8.1%). Most journals originated from the Americas region (29, 39.2%) and European region (28, 37.8%) and from high-income countries (n=54, 73.0%). Median IF was 1.55 (interquartile range (IQR) 0.89-2.40). Journals written in English (1.77 [IQR 1.00-2.87], p=0.032) and from high-income countries (1.81 [IQR 1.0-2.70], p=0.046) had highest median IF. When excluding outliers, there was a small, positive correlation between per capita GDP and IF (β=0.021, p = 0.03, R2 = 0.097) CONCLUSION: Language concordance represents a substantial barrier to research equity in neurosurgery, limiting dissemination of ideas of merit that currently have inadequate outlets for readership. Initiatives aimed at increasing the accessibility of neurosurgical publishing to underrepresented authors are essential.

    Evaluation of the National Institutes of Health-Supported Relative Citation Ratio among Fellowship trained American Orthopaedic Joint Reconstruction Surgery Faculty: A New Bibliometric Measure of Scientific Influence.
    Dane M Pizzo, Nareena Imam, Suleiman Y Sudah, Robert D Faccone, Micky Akinrodoye, Joseph E Manzi, Mariano E Menendez, Mark W Gesell.
       BACKGROUND: The Relative Citation Ratio (RCR), a novel National Institutes of Health-Supported measure of research productivity, allows for accurate interdisciplinary comparison of publication influence. This study evaluates the RCR of fellowship trained Adult Reconstructive Orthopaedic Surgeons with the goal of analyzing potentially influential physician demographics.
    METHODS: Adult Reconstruction Accreditation Council for Graduate Medical Education (ACGME) fellowship-trained faculty for orthopaedic residency programs were identified via departmental websites. The National Institutes of Health's iCite database was retrospectively reviewed for mean RCR, weighted RCR, and publication count by surgeon. Multivariate analyses were performed using the Wilcoxson rank-sum tests and Analyses of Variance testings (ANOVA) to compare sex, career length, academic rank, and professional degrees in addition to an M.D. or D.O. Significance was considered p<0.05.
    RESULTS: A total of 488 fellowship trained Adult Reconstruction faculty from 144 programs were included in the analysis. Overall, faculty recorded a median RCR of 1.65 (IQR 1.01 - 2.28) and a median weighted RCR of 16.59 (IQR 3.98 - 61.92). Weighted RCR and total number of publications were associated with academic rank and career longevity, while mean RCR was associated with academic rank. Median RCR ranged from 1.12 to 1.87 for all subgroups.
    CONCLUSION: Adult Reconstruction faculty are exceptionally productive and generate highly impactful studies as evidenced by the high median RCR value relative to the National Institute of Health standard value of 1.0. Our data has important implications in the assessment of grant outcomes, promotion, and continued evaluation of research influence within the hip and knee community.

    Worldwide Research Trends on Milk Containing Only A2 β-Casein: A Bibliometric Study.
    Lucía Jiménez-Montenegro, Leopoldo Alfonso, José A Mendizabal, Olaia Urrutia.
      The protein fraction of β-casein may play a key role in the manifestation of a new intolerance: milk protein intolerance. The most common forms of β-casein among dairy cattle breeds are A1 and A2 β-casein. During gastrointestinal digestion of A1 β-casein, an opioid called peptide β-casomorphin-7 (BCM-7) is more frequently released, which can lead to adverse health outcomes. For that reason, novel products labelled as "A2 milk" or "A1-free dairy products" have appeared on the market. In this context, a bibliometric analysis on A2 β-casein research was carried out through the Web of Science (WoS) database. The main objective of this work was to provide an overview of the state of the art in the field of β-casein A2 by analyzing the number of publications per year, trends in thematic content, the most frequently used terms, and the most important institutions and countries in the field. This bibliometric study showed that a greater effort is needed to determine the possible implications of this novel product for human health and the market.

    Canadian academics' use of predatory journals.
    Maureen Babb.
       Introduction: Predatory journals have been acknowledged as an increasing concern in the scholarly literature over the last decade, but research on the subject has been sparse. Research that has focused on predatory journals in the Canadian context has been even rarer, and limited to work focused on a single university. This study explores publishing trends in predatory journals by authors affiliated with Canadian universities.
    Methods: Articles published by authors at 30 Canadian universities, including all universities in the U15, were pulled from select predatory journals. Key data including author affiliation, article type, discipline, and grant information were extracted from the articles.
    Results: All universities in the study were found to have publications in predatory journals. The health sciences accounted for 72% of the publications, and the sciences for 20%. Research articles accounted for 50% of the articles. Opinion, editorial, or commentary pieces accounted for 24% and 19% were review articles. Grant funding was indicated in 34% of the articles, with NSERC and CIHR being top funders. The research-intensive U15 universities were found to publish more in predatory journals than their non-U15 compatriots, even when the universities were of similar size.
    Discussion: Canadian scholars were found to publish in predatory journals, particularly those scholars from the health sciences and research-intensive U15 universities. Grant funding was common, and often came from high profile funders like NSERC and CIHR. This study suggests that policy and education initiatives may be warranted in Canadian contexts, especially in the health sciences and at research-intensive universities.

    COVID-19 burden, author affiliation and women's well-being: A bibliometric analysis of COVID-19 related publications including focus on low- and middle-income countries.
    Lotus McDougal, Nabamallika Dehingia, Wendy Wei Cheung, Anvita Dixit, Anita Raj.
       Background: Published literature documents tremendous gender inequities in the social, economic and health effects of the COVID-19 pandemic, but less evidence has come from low- and middle-income countries (LMICs) and even less from LMIC-based authors. We examine whether a) COVID-19 burden and b) LMIC-based authorship were associated with academic publications related to COVID-19 and women's well-being in LMICs.
    Methods: We reviewed academic articles on COVID-19 and women's well-being in LMICs published between February 2020 and May 2021 (n=1076 articles), using six electronic databases (PubMed, Web of Science, PsycInfo, EconLit, RePeC, NBER). Multilevel, mixed effects linear regressions assessed the relationships between each of our independent variables - a) COVID-19 burden (cases/100 population, deaths/100 population, deaths/cases) and b) author's country of primary affiliation, with publications related to COVID-19 and women's well-being, both overall and stratified by country income group.
    Findings: Eight-eight percent of articles had lead and/or senior authors affiliated with in-country institutions. Linear mixed effect models indicate that COVID-19 cases and case fatality ratios in a country were significantly and positively associated with the number of publications related to COVID-19 and women's well-being, though these relationships were significant only in upper-middle income group countries in stratified analyses. LMIC lead and senior authorship were also significantly and positively associated with our outcome, after adjusting for COVID-19 burden.
    Interpretation: While the majority of COVID-19 research examining women's well-being in LMICs in the first year and a half of the pandemic included country-affiliated author leadership, there were important gaps in representation. Findings highlight the importance of LMIC-based scholars to build local and gendered research in crises.

    Citation Bias, Diversity, and Ethics.
    Keisha S Ray, Perry Zurn, Jordan D Dworkin, Dani S Bassett.
      How often a researcher is cited usually plays a decisive role in that person's career advancement, because academic institutions often use citation metrics, either explicitly or implicitly, to estimate research impact and productivity. Research has shown, however, that citation patterns and practices are affected by various biases, including the prestige of the authors being cited and their gender, race, and nationality, whether self-attested or perceived. Some commentators have proposed that researchers can address biases related to social identity or position by including a Citation Diversity Statement in a manuscript submitted for publication. A Citation Diversity Statement is a paragraph placed before the reference section of a manuscript in which the authors address the diversity and equitability of their references in terms of gender, race, ethnicity, or other factors and affirm a commitment to promoting equity and diversity in sources and references. The present commentary considers arguments in favor of Citation Diversity Statements, and some practical and ethical issues that they raise.

    Hotspot Mining in the Field of Library and Information Science under the Environment of Big Data.
    Shujie Jiang.
      Currently, with the implementation of big data strategies in countries all over the world, big data has achieved vigorous development in various fields. Big data research and application practices have also rapidly attracted the attention of the library and information field. Objective. The study explored the current state of research and research hotspots of big data in the library and information field and further discussed the future research trends. Methods. In the CNKI database, 16 CSSCI source journals in the discipline of library information and digital library were selected as data sources, and the relevant literature was retrieved with the theme of "big data." The collected literature was excluded and expanded according to the citation relationship. Then, with the help of Bicomb and SPSS, co-word analysis and cluster analysis would be carried out on these literature results. Results. According to the findings of the data analysis, the research hotspots on the topic mainly focus on five major research themes, namely, big data and smart library, big data and intelligence research, data mining and cloud computing, big data and information analysis, and library innovation and services. Limitations. At present, the research scope and coverage on this topic are wide, which leads to the research still staying at the macro level. Conclusions. Big data research will remain one of the hotspots in the future. However, the most study is still limited to the perspective of library and information and has not yet analyzed the research status, research hotspots, and development trends in this field from the perspective of big data knowledge structure. Moreover, machine learning, artificial intelligence, knowledge services, AR, and VR may be new directions for future attention and development.

    Development of the Arabic Health Measures database: a bibliometric analysis of Arabic health-related measures.
    Nada M Albawardi, Quratulain Shaikh, Wejdan Alahaideb, Maryam Alamasi, Doaa Aljasser, Lama Alrasheed, Sultanah H Alsulaiman, Abdullah F Alghannam.
       BACKGROUND: To develop an open-access database of Arabic health measures intended for use by researchers and healthcare providers, along with a bibliometric analysis of the measures included in the database.
    METHODS: A search was conducted up to 31 December 2021 in PubMed, Embase, CINAHL, SAGE, Springer and Elsevier for published articles or abstracts with keywords "Arabic" AND "translation", "adaptation" OR "validation". Information on the measure and the methodology used in the study was then entered into a database. An open-access platform was developed to allow users to search for measures according to their needs. A bibliometric analysis of the articles and measures was then conducted.
    RESULTS: A total of 894 publications met the inclusion criteria. The articles discussed 716 measures that were developed using participants from at least 38 countries. The number of measures for adults was five times that for children. Mental health was the most frequent construct assessed (11.5%), followed by "function/disability" measures (10.6%). The majority of measures (54%) required 5 minutes or less to complete. Approximately 17% of the tools were available directly from the article. Saudi Arabia and Lebanon had the greatest number of publications, with 217 (23%) and 114 (12%), respectively. The majority of the publications included reporting of the validation and reliability of the instruments (64% and 56%, respectively).
    CONCLUSIONS: There is a paucity of research on the quantity and quality of Arabic health measures. Similar to previous reviews, we found the number of publications on Arabic measures to be limited in comparison to those in English; however, it is encouraging that the number of publications appears to have increased steadily over the past decade. While we found the majority of publications reported on psychometric testing, we are unable to comment on the quality of the methodology used, and further investigation into this area is recommended. As the Arabic Health Measures database will facilitate the search for health instruments that have published data on their development, this will increase their visibility and use in research and clinical settings.

    Australian Trends in Academic Literature Concerned With Family and Domestic Violence Perpetrators: A Bibliometric Literature Review.
    Emi Patmisari, Helen McLaren.
      In this article, we used a novel hybrid approach to review literature concerned with family and domestic violence (FADV) perpetrators. Our intention was to chart the research and publication activity of authors with Australian affiliation to identify homegrown evidence related to stopping the perpetration of violence. This involved systematic searching of literature from the Scopus electronic database, utilization of VOSviewer to sort keyword co-occurrences and authorship linking for 1,494 publication records over a 30-year period, and the review of 21 articles with perpetrator focus, identified from the 50 most cited publications. We found that Australians' authoring interests in FADV, over the last three decades, with perpetrator focus were predominantly concentrated on gender, rape and sexual assault, coercive control, and child abuse. In the most cited literature, six major themes were identified: perpetrator motivations, perpetrator interventions, patterns of violence, pandemic duet, perception of blame, and cyberstalking and violence. An upward curve in Australian authoring activity in the period under review aligns with societal shifts in which FADV was once considered a private issue and has now become ubiquitous in the public domain. Our findings revealed that research into perpetrators is insufficient to promote a zero-tolerance approach to FADV. Our corresponding in-depth literature review provides valuable insights surrounding perpetrator intervention programs with the goal of more effectively addressing the emerging challenge of technology-facilitated coercive control.

    The uptake of the international pressure ulcer/injury prevention and treatment guidelines in the scientific literature: A systematic analysis of two major citation databases.
    Jan Kottner, Monira El Genedy-Kalyoncu.
       BACKGROUND: The European Pressure Ulcer Advisory Panel, the National Pressure Injury Advisory Panel and the Pan Pacific Pressure Injury Alliance developed international Clinical Practice Guidelines of the prevention and treatment of pressure ulcers/injuries in 2009, 2014, and 2019. Despite substantial dissemination efforts, evidence about guideline dissemination and uptake in the international literature is lacking.
    AIM: The aim of this review was to capture to the greatest detail possible the number of the citations of the three published Clinical Practice Guidelines.
    METHODS: The citation databases Web of Science and Scopus were searched for citations of the 2009, 2014 and 2019 Clinical Practice Guidelines including all derivative products including short versions and translations. Two separate search strategies were iteratively developed to ensure highest sensitivity.
    RESULTS: The Cited Reference Search in Web of Science identified hundreds of different referencing formats with more than 2000 citing articles. The Scopus search revealed 250 different reference formats and more than 2000 citation counts. After publication there was a gradual increase of citations that peaks approximately after four years.
    CONCLUSION: The three Clinical Practice Guidelines including all derivate versions had a substantial uptake in the scientific literature. This supports the assumption that the guideline dissemination strategies were and are successful.

    Characteristics of Blacklisted Journals: Evidence from Chinese-language Academic Journals.
    Gengyan Tang, Jingwen Jia.
      Some institutions have issued blacklists of academic journals in China and use them as a basis for research evaluation. However, due to a lack of transparent formulation criteria, the characteristics of blacklisted journals remain unclear. Using blacklisted academic journals of the East China University of Political Science and Law, this study analyzed differences in characteristics between blacklisted and non-blacklisted journals via web surveys and statistical analyses. Statistically significant differences were detected for article review time, article processing charges (APCs), the number of editorial board members, and the journal impact factor. There was no significant difference in the number of editors. While there is scientific merit in creating and publishing a blacklist of academic journals, the list development process requires more rigorous evaluation and a public process of development.

    Impact Factor JUMPS After the 2020 COVID-19 Pandemic: A Retrospective Study in Radiology, Nuclear Medicine & Medical Imaging Journals.
    Maria-Del-Carmen Garcia-Blanco, Alberto Valdez-Valdes, Sergey K Ternovoy, Nallely Bueno-Hernandez, Ernesto Roldan-Valadez.
       ABSTRACT: One of the most widely applied methods for evaluating a research paper's quality is the impact factor (IF). The term JUMPS was applied to the IF in an article published in PubMed in 2021, describing an increase of more than 40% of IF. In this study, we aimed to compare the growth rate of IF JUMPS in Radiology, Nuclear Medicine & Medical Imaging in the last 6 years. This retrospective study calculated the growth rate (JUMP) in IF from 2015 to 2020. We used the Friedman and Wilcoxon signed ranks tests to calculate the statistically significant difference in IF from 2015 to 2020 and the 2019 to 2020 difference. We classified JUMPS in negative growth rate, quartiles, and journals with >100%. Three journals had more than 100% IF growth rate during 2020 (Zeitschrift fur Medizinische Physik, Journal of the Belgian Society of Radiology, and Ultrasound Quarterly). A 76% to 100% growth rate was observed in another 4 journals (3.2%), and 8 journals (6.3%) depicted a 51% to 75% percentage of change. Repeated measures analyses showed a significant difference (P < 0.001). During the COVID-19 pandemic, several journals in the Radiology, Nuclear Medicine & Medical Imaging category increased their IF by 50%. Knowing the growing trends in this category might supplement the assessment of target journals for authors looking to submit their works.

    Reliability of citations of medRxiv preprints in articles published on COVID-19 in the world leading medical journals.
    Jean-Francois Gehanno, Julien Grosjean, Stefan J Darmoni, Laetitia Rollin.
       INTRODUCTION: Preprints have been widely cited during the COVID-19 pandemics, even in the major medical journals. However, since subsequent publication of preprint is not always mentioned in preprint repositories, some may be inappropriately cited or quoted. Our objectives were to assess the reliability of preprint citations in articles on COVID-19, to the rate of publication of preprints cited in these articles and to compare, if relevant, the content of the preprints to their published version.
    METHODS: Articles published on COVID in 2020 in the BMJ, The Lancet, the JAMA and the NEJM were manually screened to identify all articles citing at least one preprint from medRxiv. We searched PubMed, Google and Google Scholar to assess if the preprint had been published in a peer-reviewed journal, and when. Published articles were screened to assess if the title, data or conclusions were identical to the preprint version.
    RESULTS: Among the 205 research articles on COVID published by the four major medical journals in 2020, 60 (29.3%) cited at least one medRxiv preprint. Among the 182 preprints cited, 124 were published in a peer-reviewed journal, with 51 (41.1%) before the citing article was published online and 73 (58.9%) later. There were differences in the title, the data or the conclusion between the preprint cited and the published version for nearly half of them. MedRxiv did not mentioned the publication for 53 (42.7%) of preprints.
    CONCLUSIONS: More than a quarter of preprints citations were inappropriate since preprints were in fact already published at the time of publication of the citing article, often with a different content. Authors and editors should check the accuracy of the citations and of the quotations of preprints before publishing manuscripts that cite them.

    Leonard Ensslin, Alex Gonçalvesa, Sandra Rolim Ensslin, Ademar Dutra.
       PURPOSE: - The objective of this study is to use bibliometric and systemic terms to select and analyze a set of articles dealing with occupational risk management in the civil construction industry.
    MATERIALS AND METHODS: - The Knowledge Development Process - Constructivist (ProKnow-C) was used as an intervention instrument to guide the selection of the bibliographic portfolio and to support systemic analysis.
    RESULTS: - The bibliographical portfolio was created and included 20 articles. Bibliometric highlights were relevant articles, authors, countries of origin, journals and keywords. Systemic analysis showed opportunities to contribute to the state of the art in all areas of knowledge, enabling the researcher to understand theoretical bases, gaps, and research opportunities for the theme and thus establish their research question in accordance with the established knowledge vision.
    CONCLUSIONS: - The systemic analysis of each article in the Bibliographic Portfolio based on the decision support model and areas of knowledge present in each stage of its construction measures the amplitude of the knowledge at each stage, and therefore, the completeness of or gaps in each article. This clarifies the overall state of and gaps in the field, showing opportunities for new research.

    Contribution of Social Psychology Research to the Sustainable Development Goals (SDGs). Bibliometric and Content Analysis of Spanish Publications.
    Flor Sánchez, Daniela De Filippo, Amalio Blanco, María Luisa Lascurain.
      This study analyses the publications by Spanish institutions indexed by the Web of Science in the thematic category of "Psychology, Social". The objectives are to determine whether such publications address topics related to the Sustainable Development Goals (SDGs) and to what extent the research conducted contributes to achieving the goals proposed in each of the SDGs. Publications were classified by their relationship with the SDGs using OSDG tool, and an in-depth content analysis was performed to validate the results. A corpus of 1,632 papers published by Spanish institutions was identified. The results show that 34% percent of the papers address matters related to the SDGs; 23% of these are related to Goal 3 (good health and well-being), and 5%, to Goal 5 (gender equality). For achieving SDG 3 goals, the reviewed papers evidence the need that institutions, governments and society to provide, especially for children and adolescents, healthy social environments to prevent harmful social relationships while improving individual skills to manage emotions in everyday life and promoting cultural integration. Regarding SDG 5, it should be a priority the application of effective strategies to change stereotypes, assigned sexual roles and sexist attitudes that sustain inequality and violence against women.
