       Background/purpose: Bibliometric analysis is a method for quantifying the article distribution, impact, and performance. The purpose of this study was to identify the most top-cited articles published in Journal of Dental Sciences (JDS) and further analyze their main characteristics.
    Materials and methods: Web of Science, Journal Citation Reports database was searched to retrieve the most-cited articles in JDS published from 2007 to July 31, 2022. Among the included top-cited articles, the following parameters were recorded and analyzed: article title, article type, year, country, number of citations, and average citations pre year. Microsoft Excel was applied for the descriptive bibliometric analysis.
    Results: 41 top-cited articles were filtered from total 1165 JDS articles in Web of Science database. The results showed that 41 top-cited articles were cited between 20 and 186 times from Journal Citation Reports. Most of the article types are original article (28/41, 68.29%) following by review article (7/41, 17.07%). The majority of articles were originated from Taiwan (23/41, 56.10%). The top 4 most cited articles were relative to the research topic on COVID-19, lateral canal, guided-tissue regeneration barriers, and platelet-rich fibrin, respectively. However, articles analyzed by the average citations per year since publication were focused on COVID-19 followed by artificial intelligence.
    Conclusion: This bibliometric analysis illustrates the progress and trend of researches in JDS. The results may also offer a reference for recognizing the hot issues with the most citations in JDS.

       Background: In the past two decades, the surge of research on bacterial persisters has been inspired as increasingly concerning about the frequent failure of antibiotics treatment. This study was aimed at presenting a bibliometric and visualized analysis of relative publications on bacterial persisters, which offered insights into the development and research trends of this field.
    Methods: The Web of Science Core Collection and Ovid MEDLINE databases were utilized to retrieve relevant publications on bacterial persisters from 2001 to 2021. After manual selection, data including titles, authors, journals, author keywords, addresses, the number of citations, and publication years were subsequently extracted. The data analysis and visual mapping were conducted with Excel, SPSS, R studio, and VOSviewer.
    Results: In this study, 1,903 relevant publications on bacterial persisters were included. During 2001-2021, there was an exponential growth in the quantity of publications. It was found that these studies were conducted by 7,182 authors from 74 different countries. The USA led the scientific production with the highest total number of publications (859) and citation frequency (52,022). The Antimicrobial Agents and Chemotherapy was the most influential journal with 113 relevant publications. The cooccurrence analysis revealed that studies on bacterial persisters focused on four aspects: "the role of persisters in biofilms," "clinical persistent infection," "anti-persister treatment," and "mechanism of persister formation."
    Conclusion: In the past two decades, the global field of bacterial persisters has significantly increased. The USA was the leading country in this field. Mechanistic studies continued to be the future hotspots, which may be helpful to adopt new strategies against persisters and solve the problem of chronic infection in the clinic.

       BACKGROUND: The incidence of tinnitus has been increasing together with its patient impact and societal costs. Much research has been conducted in the field of tinnitus, especially on treatment modalities because there still is no cure. This study aims to analyze the evolutions and developments in the scientific output relating to tinnitus.
    METHODS: We analyzed the Science Citation Index Expanded featured articles in the Web of Science Core Collection relating to tinnitus from 1980 to 2020. The publications were analyzed by characteristics such as the countries and institutions; journals; the most cited articles and references; and the most frequently used words in the abstracts and keywords.
    RESULTS: In total, 8282 articles relating to tinnitus were identified in Web of Science. The number of publications has been significantly increasing after the 1990's. Of the 8282 articles, a major part originated from the American and European institutions. Most articles originated from high-impact journals, which consequently also covered the most cited papers. A major interest was seen in areas about treatment and pathogenic mechanisms.
    CONCLUSION: This bibliometric analysis here indicated an increasing trend in tinnitus research from 1980 to 2020, particularly with the increase of tinnitus burden and the societal costs by it. Specific interest has been seen in the specific tinnitus pathophysiological mechanisms and treatment. Individual researchers and institutions will gain a new perspective on their future studies based on the bibliometric data in our paper. They could also benefit for the publication of their articles by being aware of possible collaborations and active journals publishing on tinnitus.

      Background: Over the past decade, many studies in the field of transcranial direct current stimulation (tDCS) in stroke have been published in scholarly journals. However, a scientometric analysis focusing on tDCS after stroke is still missing. The purpose of this study is to deliver a bibliometric analysis to investigate the global hotspots and frontiers in the domain of tDCS in stroke from 2012 to 2021. Methods: Articles and reviews related to tDCS in stroke were retrieved and obtained from the Web of Science core collection database from 2012 to 2021. Data visualization and analysis were conducted by using CiteSpace, VOSviewer, and Microsoft Excel 2019. Results: Finally, 371 publications were included in the scientometric analysis, including 288 articles and 83 reviews. The results showed that the number of publications per year increased from 15 to 68 in the last 10 years. Neurosciences was the main research hotspot category (n = 201). Frontiers in Human Neuroscience was the most published journal with 14 papers. The most productive author, institution, and country were Fregni F (n = 13), the League of European Research Universities (n = 37), and the United States of America (n = 98), respectively. A burstness analysis of keywords and the literature indicated that current studies in the field of tDCS in stroke focused on poststroke aphasia, tDCS combined with robotic therapy, and anatomical parameters. Conclusion: The research of tDCS in stroke is predicted to remain a research hotspot in the future. We recommend investigating the curative effect of other different tDCS closed-loop rehabilitation methods for different stroke dysfunctions. In conclusion, this bibliometric study presented the hotspots and trends of tDCS in stroke over the last decade, which may help researchers manage their further studies.

    Junhui Hou, Zongwei Lv, Yuan Wang, Xia Wang, Yibing Wang, Kefeng Wang.
      Percutaneous nephrolithotomy (PNL) has been used in the treatment of urolithiasis for more than 20 years. However, bibliometric analysis of the global use of PNL for urolithiasis is rare. We retrieved the literatures on PNL and urolithiasis from Web of science core collection database. VOSviewer was used to analyze keywords, citations, publications, co-authorship, themes, and trend topics. A total of 3103 articles were analyzed, most of which were original ones. The most common keywords were "percutaneous nephrology" and "urolithiasis", both of which were closely related to "ureteroscopy". Journal of Urology and Zeng Guohua from the First Affiliated Hospital of Guangzhou Medical University were the most published journal and author in this field. The most productive country was the United States, and its closest partners were Canada, China, and Italy. The five hot topics were the specific application methods and means, risk factors of urolithiasis, the development of treatment technology of urolithiasis, the characteristics, composition, and properties of stones, and the evaluation of curative effect. This study aimed to provide a new perspective for PNL treatment of urolithiasis and provided valuable information for urologic researchers to understand their research hotspots, cooperative institutions, and research frontiers.

    Yao Tan, Chuanhe Zhang, Deshuang Li, Jianguo Huang, Ziling Liu, Tianyu Chen, Xuyan Zou, Bo Qin.
       BACKGROUND: Immunosenescence, the aging of the immune system, leads to a decline in the body's adaptability to the environment and plays an important role in various diseases. Immunosenescence has been widely studied in recent years. However, to date, no relevant bibliometric analyses have been conducted. This study aimed to analyze the foundation and frontiers of immunosenescence research through bibliometric analysis.
    METHODS: Articles and reviews on immunosenescence from 1970 to 2021 were obtained from the Web of Science Core Collection. Countries, institutions, authors, journals, references, and keywords were analyzed and visualized using VOSviewer and CiteSpace. The R language and Microsoft Excel 365 were used for statistical analyses.
    RESULTS: In total, 3763 publications were included in the study. The global literature on immunosenescence research has increased from 1970 to 2021. The United States was the most productive country with 1409 papers and the highest H-index. Italy had the highest average number of citations per article (58.50). Among the top 10 institutions, 50 % were in the United States. The University of California was the most productive institution, with 159 articles. Kroemer G, Franceschi C, Goronzy JJ, Solana R, and Fulop T were among the top 10 most productive and co-cited authors. Experimental Gerontology (n = 170) published the most papers on immunosenescence. The analysis of keywords found that current research focuses on "inflammaging", "gut microbiota", "cellular senescence", and "COVID-19".
    CONCLUSIONS: Immunosenescence research has increased over the years, and future cooperation and interaction between countries and institutions must be expanded. The connection between inflammaging, gut microbiota, age-related diseases, and immunosenescence is a current research priority. Individualized treatment of immunosenescence, reducing its negative effects, and promoting healthy longevity will become an emerging research direction.

Annals of the Rheumatic Diseases achieved the highest number of citations, H-index and IF, which showed the most excellent comprehensive strength. The individual author with the most paper authorship was Dalbeth Nicola with 241 publications and 46 H-index. Keywords and co-citation analysis discovered that pathological mechanism remains the future hotspot in gout research. It may involve gout connection with gut microbiota, NLRP3 inflammasome, xanthine oxidase, and urate-transporter ABCG2. In addition, besides metabolic diseases, the relationship between gout and heart failure may need more attention.
    CONCLUSION: This study clarified the current status and research frontier in gout over the past decade, which would provide valuable research references for later researchers. Key Points •We disclosed the current status and frontier directions of gout over the past 10 years worldwide. •We identified future hotspots of gout research, including gout connection with gut microbiota, NLRP3 inflammasome, xanthine oxidase, and urate-transporter ABCG2. •We discovered that the relationship between gout and heart status would be the research frontier.

    The 50 most cited articles and science mapping analysis of vaginal tightening.
    Kexin Che, Keke Wang, Ye Yuan, Fengyong Li, Qiang Li.
       INTRODUCTION AND HYPOTHESIS: The study was aimed at exploring the 50 most cited articles related to vaginal tightening.
    METHODS: The papers were searched through the Thomson Reuters Web of Science on 30 July 2022, and were ranked by the total number of citations. The included articles were analyzed for author, journal, country, number of citations, keywords, subject matter, and level of evidence. The search output was also imported into VOSviewer.
    RESULTS: The 50 most cited articles were cited a combined total of 2,558 times. The papers were published between 1990 and 2020, of which 86% were published between 2010 and 2020. They included 38 original articles, 8 reviews, 3 editorial articles, and 1 letter. Most articles were published in gynecology-related journals (n=30, 60%). The articles covered a wide range of topics, the most common being laser/radiofrequency treatment, vaginal tightening procedures, and urinary incontinence. The majority presented findings supported by level IV or V evidence. Through co-occurrence analysis, high-frequency words and countries were displayed well.
    CONCLUSIONS: The study shed light on frequently read articles and influential topics about vaginal tightening. The highly cited literature mainly focused on laser or radiofrequency treatments and gynecologists currently dominate the highly cited literature on vaginal tightening. The articles related to surgical treatments are low in number and evidence level so far. The co-occurrence analysis reveals the hot research content and active countries in the field. In general, the study provides useful evidence for future research and educational materials.

    Research hotspots and development trends of microRNA in ischemia-reperfusion: network analysis of academic journals oriented by bibliometric and visualization.
    Yang-Li He, Ya-Li Yang, Wen-Xing Xu, Tuan-Yu Fang, Min Zeng.
       Background: Ischemia-reperfusion (IR) injury can occur in the heart, brain, liver, lung, kidney, and other important organs, and may greatly increase disease mortality. MicroRNAs (miRNAs) have a variety of functions, including regulating cell differentiation, proliferation, and apoptosis. In the past 10 years, many studies on miRNAs in IR have been conducted. This study involved a visual analysis of these studies, and a discussion of research hotspots, trends, and frontiers of this topic.
    Methods: A total of 1,518 articles published between 2012 and 2022 on the topic of miRNA and IR and listed in the Web of Science database were analyzed visually using CiteSpace. Cooperative networks, literature citations, and keyword co-occurrence were analyzed.
    Results: Of the 1,518 articles, most were published after 2018, and a rapid growth in numbers of publications was seen after 2019. Articles from China numbered the highest, followed by the United States and Canada. It has been found that many miRNAs are involved in the occurrence of IR, with various regulatory mechanisms and signaling pathways. The literature clustering generated by literature co-citation analysis and the keyword co-occurrence network showed that the previous miRNA research on IR had mainly focused on the following topics: myocardial infarction, ischemic stroke, acute kidney injury, oxidative stress, and inflammatory response. More attention has been paid to long noncoding RNA (lncRNA) and exosomes, with much exploration having been conducted in these areas.
    Conclusions: Although miRNA is involved in the occurrence and development of IR, as a clinical intervention target for IR, further research is still needed.

    Serpil Şahin, Sevil Alkan.
       OBJECTIVES: In 2001, Turkey performed its the first successful heart transplant. Since 2011, 765 heart transplants have been conducted among 15 heart transplant centers. The scientific impact of Turkish articles on heart transplantation remains uncertain. The purpose of this study was to evaluate Turkey's contributions in international heart transplant research.
    MATERIALS AND METHODS: The bibliometric study approach was used to assess publications on heart transplantation, which included analysis of year of publication, organizations/authors, sponsorship, keywords, citations, and other characteristics. Titles, abstracts, and key words were searched in the Web of Science database for terms that included "heart" or "cardiac" and "transplantation." Methods for both quantitative and qualitative data analysis were used.
    RESULTS: During the analysis period of 1970 through 2021, 6370 article publications were retrieved with an average of 20.88 citations/article and 133 018 total citations. H index was 129. Most of the retrieved articles were from research areas of surgery (n = 2876; 45.14%), followed by transplantation (n = 2818; 44.23%) and cardiovascular system cardiology (n = 2522; 39.59%). Annual citation growth showed slow growth until 1986. The highest number of citations was seen in 2021 (n = 702). The United States led countries on articles (n = 2924; 45.9%), followed by Germany (n = 458; 7.19%), England (n = 411; 6.45%), Canada (n = 384; 6.02%), France (n = 330; 5.18%), and Spain (n = 329; 5.16%). The other 84 countries totaled 753 (11.82%) articles. Turkey ranked eighteenth with 87 publications, with Başkent University (n = 37) and Ege University (n = 13) being the leading centers on heart transplant research in Turkey.
    CONCLUSIONS: Publications from the United States continue to increase. The workload of both transplant surgery and research and publishing is challenging and Turkish researchers are encouraged to make strides at innovations.

    Publication Times and Impact Factors (IFs) in Dentistry Journals.
    Tomasz Skrzypczak, Anna Skrzypczak, Małgorzata Skrzypczak.
       INTRODUCTION:  The speed of manuscript publication in reputable journals plays a crucial role in spreading scientific novelties and may influence the number of received citations. In the present study, the authors investigated the publication speed of dentistry journals. This is crucial for both authors, who desire rapid dissemination of their findings, and patients in need, who seek new therapies.
    MATERIALS AND METHODS:  This was a cross-sectional bibliometric analysis of published dentistry journals. A list of dentistry journals featured in the 2021 Journal Citation Report was downloaded. A total of five random original articles were extracted from each of these journals. These articles were published between January and December 2020. Median and interquartile range (IQR) times from submission to acceptance, publication in print, online publication, time from acceptance to in print and online publication were calculated. The correlation between publication times and journal impact factor (IF) was examined.
    RESULTS:  A total of 89 journals were included. Individual time from submission to acceptance (peer review time) ranged from 6 to 279 days, the combined median peer review time was 115 (80-159) days. The overall median time from acceptance to online or print publication was 17 (12-38) and 153 (92-249) days, respectively. Journals with available data concerning publication times tended to have higher IF than others. Only journals that did not have available time from acceptance to online publication had higher IF. There were negative correlations between times from submission (r = -0.442, p = 0.007), acceptance (r = -0.616, p < 0.001) to in-print publication, and IF. There were no correlations between IF and time from submission to acceptance, acceptance to online publication, and submission to online publication.
    CONCLUSIONS:  Publication times availability was revealed to be an indicator of higher impacted journals, which is a potential new exponent of journal quality. Higher IF values were associated with shorter times from submission to acceptance and in-print publication, which is consistent with current editorial policies.

    Frederico Viana Machado, Carla Michele Rech, Rodrigo Silveira Pinto, Wagner de Melo Romão, Manuelle Maria Marques Matias, Gabriele Carvalho de Freitas, Fernando Antônio Gomes Leles, Henrique Kujawa.
      Participation in health has generated a large number of publications around the world. In order to know the specificities of this production in the Americas, a bibliometric analysis of articles in English, Spanish and Portuguese was carried out. Searches were carried out in the VHL, PubMed, SCOPUS, WOS and SciELO, consolidating a database with 641 references. With the help of the VOSviewer software, we analyzed citation patterns, co-authorship and the chronological distribution by countries and languages. It was possible to verify the growth of production, the quantitative relevance and the impact of the different countries. The analysis indicated that the USA concentrates the largest number of citations and Brazil, despite being the first in number of publications, is the third in number of citations. The same occurs with Brazilian journals that, with the largest number of articles, fall in the ranking of the most cited. The co-authorship analysis indicated that the University of Toronto, Fiocruz and Harvard University have the most formal collaborations with other organizations. We conclude that there are inequalities of impact, visibility and internationalization in this field, indicating obstacles to scientific development and health policies.

    Gul Zaib, Xuming Hu, Hengmi Cui.
      Avian leukosis virus (ALV) has a tremendous adverse impact on the poultry industry. Since its discovery, research on different aspects of ALV have been published. Due to the vast academic emphasis and economic importance of the ALV infection in poultry worldwide, this bibliometric analysis explored the scientific output associated with ALV utilizing the Web of Science (Core Collection) database. The relevant data were collected using the search query "AVIAN LEUKOSIS VIRUS", further refined by document types (article, book chapter, and proceedings paper). Finally, 1060 items with full records were imported in Plaintext and tab-delimited formats. The data analysis was carried out using MS Excel, VOS viewer, and R (Biblioshiny) software. Chinese and American research institutions produced the majority of papers during study time period. The Journal of Virology and Avian Diseases appeared as the favorite journal/source for publications. Apart from the avian leukosis virus and the ALV-J, the important keywords mentioned included avian leukosis virus subgroup j, chicken, and retrovirus. The analysis revealed substantial findings on ALV research, with a strong research response from the USA and China.

    The use of positron emission tomography in thyroid cancer: a bibliometric analysis.
    Liang Zhang, Yan Zhang, Shuang Liu, Yongcai Zhao, Liang Chen.
       Background: Thyroid cancer is a common malignant tumor, and its incidence is rising. Positron emission tomography-computed tomography (PET-CT) is of great value in diagnosing and monitoring thyroid cancer. The purpose of this study is to analyze the current research status of the use of PET-CT in thyroid cancer.
    Methods: We used the Science Citation Index-Expanded (SCI-E) database in the Web of Science Core Collection (WOSCC) as the data source for the literature search. The search was carried out with ("thyroid cancer" OR "thyroid carcinoma") AND "positron emission tomography", and the results were analyzed with the bibliometric R software package. The analysis included the number of documents published in this field by each country, the cooperative relationship between countries, the number of documents published by institutions, the cooperative relationship between institutions, the number of documents published by researchers, the cooperative relationship between researchers, the location of researchers being cited, the number of documents published in journals, and the use of keywords.
    Results: One thousand and six hundred and seven papers were finally included, and the number of published papers each year showed a trend of fluctuating growth before reaching a peak in 2010, followed by a decreasing trend. The United States published the largest number of documents and was cited far more frequently than other countries. The research institute with the largest number of published articles was the Memorial Sloan Kettering Cancer Center in New York, USA. The cooperation relationship of authors presented a clustered distribution, and the authors in the same cluster often came from the same research institution or country. The professional journal "Thyroid" published the largest amount of studies in this field. According to Bradford's rules, nine core journals in this field were determined. The result of our keyword analysis showed that the most commonly used keyword was "positron emission tomography", followed by "cancer" and "carcinoma". The research in this field focused on follow-up and management of thyroid cancer, especially papillary thyroid cancer.
    Conclusions: The number of studies in this field shows a decreasing trend, and PET is essential in the follow-up monitoring of thyroid cancer patients.

    Impact of COVID-19 Dentistry-Related Literature: An Altmetric Study.
    Konstantina Delli, Christos Livas, Nikolaos G Nikitakis, Arjan Vissink.
       INTRODUCTION: Scientific literature on COVID-19 has grown rapidly during the pandemic. The aim of this study was to provide a comprehensive overview of the popularity on the web of the available dental publications on COVID-19 and to examine associations amongst article characteristics, online mentions, and citations.
    MATERIALS AND METHODS: An Altmetric Explorer search was conducted for COVID-19 articles published in dental journals using 3 keywords: COVID-19, SARS-CoV-2, and pandemic. The following Altmetric data were collected: Altmetric attention score (AAS), mentions by news outlets, tweets, Mendeley readers, and Web of Science citations. Additionally, article title, type, topic, origin and open access status, journal title, quartile of impact factor (IF) distribution, and time lapse between COVID-19 pandemic onset and publication date were analysed.
    RESULTS: In all, 253 articles published in 48 dental journals were eligible for the study. AAS was significantly influenced by article topic, type, origin, and journal IF quartile. There was a negligible correlation between AAS and Web of Science citations. Mendeley was the only Altmetric source highly correlated with citations.
    CONCLUSIONS: There was substantial online interest in COVID-19 dentistry-related literature, as depicted by the AAS of the reviewed articles and social media metrics. Mendeley reader counts were highly correlated with citations, and they may therefore be valuable in research impact evaluation.

    Research Trends of Vitamin D Metabolism Gene Polymorphisms Based on a Bibliometric Investigation.
    Mohamed Abouzid, Marta Karaźniewicz-Łada, Basel Abdelazeem, James Robert Brašić.
      Vitamin D requires activation to show its pharmacological effect. While most studies investigate the association between vitamin D and disease, only a few focus on the impact of vitamin D metabolism gene polymorphisms (vitDMGPs). This bibliometric study aims to provide an overview of current publications on vitDMGPs (CYP27B1, CYP24A1, CYP2R1, CYP27A1, CYP2R1, DHCR7/NADSYN1), compare them across countries, affiliations, and journals, and inspect keywords, co-citations, and citation bursts to identify trends in this research field. CiteSpace© (version 6.1.R3, Chaomei Chen), Bibliometrix© (R version 4.1.3 library, K-Synth Srl, University of Naples Federico II, Naples, Italy), VOSviewer© (version 1.6.1, Nees Jan van Eck and Ludo Waltman, Leiden University, Leiden, Netherlands) and Microsoft® Excel 365 (Microsoft, Redmond, Washington, USA) classified and summarized Web of Science articles from 1998 to November 2022. We analyzed 2496 articles and built a timeline of co-citations and a bibliometric keywords co-occurrence map. The annual growth rate of vitDMGPs publications was 18.68%, and their relative research interest and published papers were increasing. The United States of America leads vitDMGPs research. The University of California System attained the highest quality of vitDMGPs research, followed by the American National Institutes of Health and Harvard University. The three productive journals on vitDMGPs papers are J. Steroid. Biochem. Mol. Biol., PLOS ONE, and J. Clin. Endocrinol. Metab. We highlighted that the vitDMGPs domain is relatively new, and many novel research opportunities are available, especially those related to studying single nucleotide polymorphisms or markers in a specific gene in the vitamin D metabolism cycle and their association with disease. Genome-wide association studies, genetic variants of vitDMGPs, and vitamin D and its role in cancer risk were the most popular studies. CYP24A1 and CYB27A1 were the most-studied genes in vitDMGPs. Insulin was the longest-trending studied hormone associated with vitDMGPs. Trending topics in this field relate to bile acid metabolism, transcriptome and gene expression, biomarkers, single nucleotide polymorphism, and fibroblast growth factor 23. We also expect an increase in original research papers investigating the association between vitDMGPs and coronavirus disease 2019, hypercalcemia, Smith-Lemli-Opitz syndrome, 27-hydroxycholesterol, and mendelian randomization. These findings will provide the foundations for innovations in the diagnosis and treatment of a vast spectrum of conditions.

      Women are less likely to be senior authors, invited to write in scientific journals, and to be cited in high impact journals. The aim of this study was to investigate trends in authorship and gender differences in peer-reviewed burn literature over 13 years. We performed a retrospective analysis of original research articles published from January 2009 to September 2021 in three burn journals. A gender determination application was used to categorize the gender of the first and senior author. Of the 3,908 articles analyzed, 42.5% had a woman first author and 27.6% had a woman senior author. We identified 2,029 unique senior authors, 29.0% of whom were women. Woman senior authorship was associated with increased odds of woman first authorship [OR=2.31 (95% CI 2.00, 2.67); p<0.001]. The percentage of papers with a woman senior author increased from 17.8% in 2009 to 35.7% in 2021. If this 1.0% (95% CI: 0.50 - 1.51%) linear trend increase per year in woman senior authorship continues, we will expect to see equal proportions of woman and man senior authors in the included journals starting in 2037. The field of burn care is far from reaching gender parity with respect to authorship of peer-reviewed publications. Supporting and encouraging gender concordant and discordant first:last authorship dyads in mentorship as well as redistributing obligations that may detract from authorship opportunities are potential ways to improve parity in authorship and academia.

    Supporting grant reviewers through the scientometric ranking of applicants.
    Balázs Győrffy, Boglarka Weltz, István Szabó.
       INTRODUCTION: Comparing the scientific output of different researchers applying for a grant is a tedious work. In Hungary, to help reviewers to rapidly rank the scientific productivity of a researcher, a grant decision support tool was established and is available at www.scientometrics.org. In the present study, our goal was to assess the impact of this decision support tool on grant review procedures.
    METHODS: The established, publicly available scientometric portal uses four metrics, including the H-index, the yearly citations without self-citations, the number of publications in the last five years, and the number of highly cited publications of a researcher within eleven independent scientific disciplines. Publication-age matched researchers are then ranked and the results are provided to grant reviewers. A questionnaire was completed by reviewers regarding utilization of the scientometric ranking system. The outcome of the grant selection was analyzed by comparing scientometric parameters of applying and funded applicants. We compared three grant allocation rounds before to two grant allocation rounds after the introduction of the portal.
    RESULTS: The scientometric decision support tool was introduced in 2020 to assist grant selection in Hungary and all basic research grant applicants (n = 6,662) were screened. The average score of funded proposals compared to submitted proposals increased by 94% after the introduction of the ranking. Correlation between ranking scores and actual grant selection was strong in life and material sciences but some scientific panels had opposite correlation in social sciences and humanities. When comparing selection outcome to H-index across all applicants, both type I and type II errors decreased. All together 540 reviewers provided feedback representing all eleven scientific disciplines and 83.05% of the reviewers (especially younger reviewers) found the ranking useful.
    CONCLUSIONS: The scientometric decision support tool can save time and increase transparency of grant review processes. The majority of reviewers found the ranking-based scientometric analysis useful when assessing the publication performance of an applicant.

       OBJECTIVES: Educational research is essential for rationalizing curriculum design, improving evaluation systems, and updating teaching content. This bibliometric study aimed at analyzing the characteristics of publications relevant to endodontic education, thus forming a comprehensive scope of this research area.
    METHODS: The search was conducted in the Web of Science Core Collection database in May 2022. Knowledge units of the included publications, such as year of publication, journal, country/institution/author, keywords, and highly cited articles/references, were analyzed.
    RESULTS: The United States ranked first in the number of articles with a total of 17 articles. The majority of included articles were published in Journal of Dental Education (n = 25), International Endodontic Journal (n = 21), and European Journal of Dental Education (n = 14). The top 3 most frequent keywords were Endodontics, Education, and Root canal treatment. The main topic in endodontic education were curriculum, preclinical education, educational technology, and continuing education.
    CONCLUSION: Forming a full scope of the endodontic research area, this bibliomertic analysis can help mine the hot topic, predict the frontiers in the field and provide the data necessary to determine the direction of research, rationalize resource allocation, and formulate policy.

    Realistic Assessment of Research Publications by Neurosurgery Residency Applicants.
    Hunter L Hasley, Geoffrey R O'Malley, Suraj Bala, Hannah E Weisman, Patrick A Roth.
       OBJECTIVE: Neurosurgical residency applicants' prior research experience can amplify their ability to stand out to prospective neurosurgery programs. We attempted to accurately quantify the number of research publications coauthored by applicants by analyzing the publications of those who matched into neurosurgery in the 2021 Match.
    METHODS: Scopus, a peer-reviewed literature database, was queried for publications by those who matched into neurosurgery in the 2021 Match prior to the finalization of rank lists. Conference papers, abstracts, and book chapters were excluded to determine an accurate average of actual publications. Descriptive statistics for resident publication data were utilized, with a Mann-Whitney U test used to compare research productivity between male and female residents.
    RESULTS: There were 234 positions filled by the 2021 Match and 233 neurosurgical residents were identifiable in this study. 187 residents matching from US MD and DO programs were identified with 946 total publications, an average of 5.1 publications per resident. Analysis of descriptive statistics revealed type of research conducted, authorship information, most published journals, and citation data. Significant differences were found in the number of publications between male and female applicants with averages of 5.6 and 3.8 publications, respectively.
    CONCLUSIONS: Students matriculating to neurosurgery residency programs display a wide range of research productivity; however, typical US MD and DO applicants have coauthored a mean of 5.1 and a median of 4.0 publications. This information may assist program directors in weighing applicants' research background and give medical students interested in the field reasonable research expectations.

    A Bibliometric Analysis and Review of Nudge Research Using VOSviewer.
    Chenjin Jia, Hasrina Mustafa.
      With growing demands of decision making in the current era, the impact of the drivers behind individuals' preferences and institutional strategies becomes prominent. Coined in 2008, nudge is used to describe incentives for individuals' choices with foreseeable outcomes but without exclusion of alternative choices or reliance on financial stimuli. Consequently, nudge and its application in real-world situations led to a prosperous surge of studies in multiple disciplines. However, we are still facing a dearth of in-depth understanding of the status quo and future directions of research on nudge in a comprehensive fashion. To address the gap in knowledge, the present study adopted a bibliometric analysis of the existing literature related to the investigation and application of nudge by analyzing 1706 publications retrieved from Web of Science. The results indicated that (a) being a relatively newly developed theory, interest in nudge in academia has expanded both in volume and disciplines, with Western scholars and behavioral economists as the backbones; (b) future studies in nudge-related fields are expected to consolidate its current frontiers in individual behaviors while shedding light on new territories such as the digitalized environment. By incorporating state-of-the-art technologies to investigate extant research, the present study would be pivotal for the holistic understanding of the studies on nudge in recent years. Nevertheless, the inclusiveness and comprehensiveness of the review were limited by the size of the selected literature.

    The effect of the COVID-19 pandemic on gendered research productivity and its correlates.
    Eunrang Kwon, Jinhyuk Yun, Jeong-Han Kang.
      Female researchers may have experienced more difficulties than their male counterparts since the COVID-19 outbreak because of gendered housework and childcare. To test it, we constructed a unique dataset that connects 15,280,382 scholarly publications and their 11,828,866 authors retrieved from Microsoft Academic Graph data between 2016 and 2020 to various national characteristics from LinkedIn, Johns Hopkins Coronavirus Resource Center, and Covid-19 Community Mobility Reports from Google. Using the dataset, this study estimated how much the proportion of female authors in academic journals on a global scale changed in 2020 (net of recent yearly trends). We observed a decrease in research productivity for female researchers in 2020, mostly as first authors, followed by last author position. We also identified various factors that amplified the gender gap by dividing the authors' backgrounds into individual, organizational and national characteristics. Female researchers were more vulnerable when they were in their mid-career, affiliated to the least influential organizations, and more importantly from less gender-equal countries with higher mortality and restricted mobility as a result of COVID-19. Our findings suggest that female researchers were not necessarily excluded from but were marginalized in research since the COVID-19 outbreak and we discuss its policy implications.

    Quality and safety education for nurses: A bibliometric analysis.
    Gwen Sherwood, Cheryl B Jones, Jamie L Conklin, Adam Dodd.
       PURPOSE: Since its origin in the United States in 2005, Quality and Safety Education for Nurses (QSEN) has guided nurses' preparation for alleviating preventable harm and improving quality safe care. QSEN's value is illustrated through specific inclusion in the competency-based 2021 American Association for Colleges of Nursing (AACN) Essentials. The purpose of this bibliometric analysis is to explore publication patterns of the extant QSEN literature to assess QSEN's spread and global penetration and to map the available knowledge and data regarding quality and safety education for nurses.
    DESIGN: Bibliometric analysis.
    METHOD: Two QSEN investigators and two health science librarians completed database searches to identify articles with keywords QSEN or Quality and safety education for nursing. Inclusion criteria were (1) QSEN-specific and (2) published in a peer-reviewed journal. Using PRISMA screening, the final sample included 221 articles between 2007 and 2021.
    RESULTS: Average annual QSEN publications was 14.5 articles; the highest was 26 publications in 2017. Article types were 84 research, 77 descriptive/reviews, 28 quality improvement projects or case studies, 20 statements, and 12 editorials. Focus analysis revealed 165 education articles, 35 clinical practice, 17 professional development, and 4 leadership/administration. Fourteen journals published three or more; eight were education journals. Nine topic clusters indicated areas of publication focus, including clinical teaching, simulations, performance, context, and criteria of analysis, factors of efficacy, innovation and advanced practice, patient care and outcomes, academic concepts, and research frameworks.
    CONCLUSIONS: Results reveal far less QSEN penetration for guiding professional practice, research measuring outcomes and impact, and global collaboration to examine cultural implications for diversity and inclusion. Results present future recommendations to assure all nurses worldwide have access to competency development to alleviate preventable healthcare harm.
    CLINICAL RELEVANCE: Originating in the United States (US), the QSEN project provided the seminal framework for transforming education and practice through defining the six quality and safety competencies (patient-centered care, teamwork and collaboration, evidence-based practice, quality improvement, safety, and informatics) essential to alleviate preventable healthcare harm. Results reveal opportunities to advance QSEN penetration in developing professional practice, guiding research measuring outcomes and impact, and extending global collaboration to examine cultural implications for diversity and inclusion.

    Organisational Culture Research in Healthcare: A Big Data Bibliometric Study.
    Xiaoping Qin, Richard Wang, Yu-Ni Huang, Jinhong Zhao, Herng-Chia Chiu, Tao-Hsin Tung, Jeff Harrison, Bing-Long Wang.
      Across international healthcare, organisational culture and work environment have become central to all patient safety. However, there is a lack of comprehensive overview to assess and track the evolution of the literature on organisational culture in healthcare. This study aims to describe the current situation and global trends in organisational culture research in healthcare. The methodology is based on bibliometric mapping using scientific visualisation software (CiteSpace and VOSviewer). The big data were collected from the Web of Science core citation database. After applying the search criteria, we retrieved 1559 publications, which have steadily increased over the last two decades. In addition, 92 countries and regions have published studies on organisational culture in healthcare. The United States has made significant contributions to this field. In particular, organisational culture occupies an important position in the quality management of different types of care and caregiving. At the same time, organisational culture in healthcare may be inadequately researched in terms of theoretical underpinnings, which in turn leads to a lack of widespread dissemination of practice, and research on organisational culture in healthcare through evidence-based medicine may remain a significant focus and hot topic throughout the research field in the coming years.

    Trends in Integrated Plastic Surgery Applicant, Resident, and Junior Attending Research Productivity.
    Sanjay K A Jinka, Benjamin A Sarac, Austin P Seaman, Samantha L Fry, Maria T Huayllani, Jeffrey E Janis.
       INTRODUCTION: Research productivity is critical for matching into integrated plastic surgery residency. This study will identify how pre and intraresidency research productivity correlate with resident/junior attending productivity.
    MATERIALS AND METHODS: Retrospective review from 2006 to 2015 issues of the American Board of Plastic Surgery's Annual Newsletter to Diplomates was performed to identify newly board certified plastic surgeons. Only surgeons from US medical schools matching directly into integrated programs were included. Residency type/length, graduation year from medical school, and publication counts were recorded for each surgeon. Publications were categorized as preresidency, intraresidency, and junior attending (6 y post residency/fellowship training).
    RESULTS: Six hundred fifty-five integrated plastic surgery graduates were analyzed. The median number of total publications (preresidency, intraresidency, and junior attending) was 4 (interquartile range [IQR], 1 to 10). Linear regression revealed negligible correlation between preresidency and junior attending publications (r = 0.019, P = 0.002). Total publications and increasing graduation y had a significant correlation of 0.89 (P < 0.001). Graduates of fellowships had significantly increased median total publications compared to those without fellowships (7 IQR, 3 to 18 versus 3 IQR, 1 to 7, respectively, P < 0.001). Dedicated research years during residency were associated with significant (P < 0.001) increases in median total and junior attending publications. Total publications ranged from 3 (IQR, 1 to 6) to 8 (IQR, 7 to 18) for those who completed 5- and 8-y residencies, respectively.
    CONCLUSIONS: Increased preresidency research productivity is not strongly associated with increased junior attending productivity in integrated plastic surgery. Better markers are completing dedicated research years in residency or fellowship after residency.

    Quantifying the impact of strong ties in international scientific research collaboration.
    Junwan Liu, Xiaofei Guo, Shuo Xu, Yueyan Zhang.
      Tie strength has been examined as an antecedent of creativity. Although it has been discovered that international collaboration affects scientific performance, the effect of tie strength in the international collaboration network has been largely neglected. Based on international publications of 72 countries/regions published from 1993 to 2013, we combine descriptive and panel regression methods to examine how the bonding of strong collaboration ties contributes to countries' international scientific performance. Strong ties occur at an average rate of 1 in 4 collaborators, whereas countries/regions share on average 84% of articles with their strong-tie collaborators. Our quantitative results provide an explanation for this phenomenon in international collaboration: the establishment of a strong tie relationship contributes to above-average productivity and citation frequency for countries/regions. To further explore which types of strong ties tend to have stronger citation impact, we analyse the relationship between persistent and stable collaboration and publication citation impact. Experimental results show that international collaborations with greater persistence and moderate stability tend to produce high impact publications. It is noteworthy that when the collaboration period is divided into different time intervals, similar findings can be found after the same analysis procedure is carried out. This indicates that our conclusions are robust. Overall, this study provides quantitative insights into the added value of long-term commitment and social trust associated with strong collaborative partnerships in international collaboration.

    Knowledge graph of wastewater-based epidemiology development: A data-driven analysis based on research topics and trends.
    Zhihan Gao, Min Gao, Chun-Hua Chen, Yifan Zhou, Zhi-Hui Zhan, Yuan Ren.
      Wastewater-based epidemiology (WBE) has contributed significantly to the monitoring of drug use and transmission of viruses that has been published in numerous research papers. In this paper, we used LitStraw, a self-developed text extraction tool, to extract, analyze, and construct knowledge graphs from nearly 900 related papers in PDF format collected in Web of Science from 2000 to 2021 to analyze the research hotspots and development trends of WBE. The results showed a growing number of WBE publications in multidisciplinary cross-collaboration, with more publications and close collaboration between the USA, Australia, China, and European countries. The keywords of illicit drugs and pharmaceuticals still maintain research hotness, but the specific research hotspots change significantly, among which the research hotspots of new psychoactive substances, biomarkers, and stability show an increasing trend. In addition, judging the spread of COVID-19 by the presence of SARS-CoV-2 RNA in sewage has become the focus since 2020. This work can show the development of WBE more clearly by constructing a knowledge graph and also provide new ideas for the paper mining analysis methods in different fields.

    [Trends in Brazilian Research in Ergology].
    Luiz Phillipe Mota Pessanha, Isabel Cristina Dos Santos, Mayara Vieira Henriques, Raquel Cançado, Rayana Ferreira Vinagre, Alexandre de Carvalho Castro.
      This article aims to analyze trends in research on Ergology in Brazil published from 1997 to 2019, considering the nature of the publication and the potential impact of the databases in which they are published. Studies related to occupational health indicate the growing influence of Ergology in the understanding of the world of work, a fact evidenced in previous bibliometric research, of lesser breadth and scope of the databases investigated, which is why we intend to cover gaps and broaden the analysis with more up-to-date data. Using descriptors peculiar to Ergology, surveys were conducted in the Web of Science, Scopus and SciELO databases, in journals not indexed to the databases cited, and in academic productions available in the Capes catalog. The projection of Brazil in studies on Ergology was revealed, with the Southeast being the region with the highest concentration of authors and volume of publications. However, the interrelationship between researchers tends to be limited to the institutions in which they work. There is a prevalence of theses and dissertations to the detriment of articles in productions related to Ergology. Publications point to interdisciplinarity - with a predominance of Occupational Health, Education, and Psychology - and tend to feature in vehicles of lesser scientific relevance.

    Study results from journals with a higher impact factor are closer to "truth": a meta-epidemiological study.
    Andreas Heidenreich, Nora Eisemann, Alexander Katalinic, Joachim Hübner.
       BACKGROUND: Scientists, physicians, and the general public legitimately expect scholarly publications to give true answers to study questions raised. We investigated whether findings from studies published in journals with higher Journal Impact Factors (JIFs) are closer to truth than findings from studies in less-cited journals via a meta-epidemiological approach.
    METHODS: We screened intervention reviews from the Cochrane Database of Systematic Reviews (CDSR) and sought well-appraised meta-analyses. We used the individual RCT study estimates' relative deviation from the pooled effect estimate as a proxy for the deviation of the study results from the truth. The effect of the JIF on the relative deviation was estimated with linear regression and with local polynomial regression, both with adjustment for the relative size of studies. Several sensitivity analyses for various sub-group analyses and for alternative impact metrics were conducted.
    RESULTS: In 2459 results from 446 meta-analyses, results with a higher JIF were on average closer to "truth" than the results with a lower JIF. The relative deviation decreased on average by -0.023 per JIF (95% CI -0.32 to -0.21). A decrease was consistently found in all sensitivity analyses.
    CONCLUSIONS: Our results indicate that study results published in higher-impact journals are on average closer to truth. However, the JIF is only one weak and impractical indicator among many that determine a studies' accuracy.

    Citing retracted literature: a word of caution.
    Alessandro De Cassai, Francesco Volpe, Federico Geraldini, Burhan Dost, Annalisa Boscolo, Paolo Navalesi.
       INTRODUCTION: Inappropriate citation of retracted literature is a common problem in the general medical literature. In 2020, more than 2300 articles were retracted, a dramatic increase from 38 in 2000. By exploring a contemporary series of retractions by one research group, we aimed to evaluate if citations of retracted articles is occurring in the area of regional anesthesiology.
    METHODS: Using the Scopus database, we examined the full text of all the articles citing research articles coauthored by an anesthesiologist who had multiple articles retracted in 2022. After excluding the research articles citing non-retracted articles authored by the above mentioned anesthesiologist, we included in our analysis all the articles containing a retracted citation and published after the retraction notice.
    RESULTS: The search was performed on October 30, 2022, retrieving a total of 121 articles citing the researcher's work. Among the retrieved articles, 53 correctly cited non-retracted research and 37 were published before the retraction notice. Among the 31 remaining articles, 42 retracted research papers were cited. Twenty-five of the retracted articles were cited in the Discussion section of the manuscripts, 15 in the Introduction section, 1 in the Methods section (description of a technique), and one was cited in a review. No manuscript used the flawed data to calculate the sample size.
    DISCUSSION: In this contemporary example from the regional anesthesia literature, we identified that citation of retracted work remains a common phenomenon.

    Mapping the output of the global literature on the links between gut microbiota and COVID-19.
    Sa'ed H Zyoud, Muna Shakhshir, Amani S Abushanab, Amer Koni, Moyad Shahwan, Ammar A Jairoun, Samah W Al-Jabi.
       BACKGROUND: The term "human microbiota" refers to populations of microorganisms that live harmoniously in co-existence with humans. They contribute significantly to the host's immunological response when confronted with a respiratory viral infection. However, little is known about the relationship between the human microbiome and COVID-19. Therefore, our objective is to perform a bibliometric analysis to explore the overall structure and hotspots of research activity on the links between microbiota and COVID-19 at the global level.
    METHODS: The research literature on the microbiota and COVID-19 published between 2020 and 2022 was obtained from the Scopus database. Bibliometric analysis and network visualization were performed with VOSviewer.
    RESULTS: Of the 701 publications selected, the USA contributed the most (n = 157, 22.40%), followed by China (n = 118, 16.83%) and Italy (n = 82, 11.70%). Hotspots in this field were "COVID-19 is associated with an altered upper respiratory tract microbiome," "the effect of antibiotics on the gut microbiome," as well as "patient nutrition and probiotic therapy in COVID-19."
    CONCLUSIONS: The links between microbiota and COVID-19 remain an urgent concern at present, and the use of probiotics or/and antibiotics during the pandemic needs to be further improved. This landscape analysis of the links between the microbiota and COVID-19 will provide a basis for future research.

    Publication rates and characteristics of PGY2 psychiatric pharmacy resident research projects.
    Dayton L Antley, Leigh Anne Nelson, Carrie R Kriz, Courtney A Iuppa, Shelby E Lang, Nicole A Gramlich, Ellie S R Elliott, Roger W Sommi.
       Introduction: To describe the publication rates and characteristics of PGY2 psychiatric pharmacy residency projects presented as a poster presentation at the annual meetings of the College of Psychiatric and Neurologic Pharmacists (CPNP) from 2002 to 2018. (As of 2022 the organization is under the name, American Association of Psychiatric Pharmacists.).
    Methods: CPNP abstracts from even years were strategically searched in PubMed, Ovid MEDLINE, and Google Scholar. If a publication was identified, additional data were collected for characterization, including study information, journal information, author information, institutional affiliation, publication year, and time to publication.
    Results: A total of 348 abstracts were evaluated. Publication in a journal was achieved for 60 projects (17.2%), with publication rates decreasing from 2012 to 2018. The mean time to publication was 17.3 months after completion of the residency, with most projects published at 8 months. More than half (51.7%) of these projects were published in a psychiatric pharmacy journal affiliated with CPNP. Study designs were predominantly retrospective, observational, cohort studies with a focus on evaluation of a drug therapy outcome. The PGY2 resident was the first author in 90% of the publications. Forty percent included other health care professionals outside of pharmacy as a coauthor. PGY2 residencies affiliated with academic institutions had overall higher publications rates.
    Discussion: Publication rates for PGY2 psychiatric pharmacy residency projects are low and are decreasing over time despite an increasing number of PGY2 psychiatric pharmacy residency programs. This publication rate is lower than that reported in the literature for PGY2 critical care residency programs. The downward trend of publication rates for PGY2 psychiatric pharmacy residency projects is concerning.

    Global review and state-of-the-art of biomass and carbon stock in the Amazon.
    Emmanoella Costa Guaraná Araujo, Carlos Roberto Sanquetta, Ana Paula Dalla Corte, Allan Libanio Pelissari, Gabriel Agostini Orso, Thiago Cardoso Silva.
      Understanding how studies have been carried out in the region helps to understand the Amazon rainforest potential in mitigating climate change. In addition, evaluating scientific production is essential to verify the main methods and places researched. Thus, this study objective was to build an overview and identify the main gaps regarding research related to biomass and carbon stocks with the coverage limit of the Amazon rainforest. Therefore, an analysis of the publications indexed in the Scopus database was developed until 2020, performing a bibliometric analysis and a systematic and state-of-the-art review. Initially 2042 publications were obtained, of which 786 met the inclusion criteria. The first work indexed in the Scopus database related to the theme was published in 1982. Over time, it was possible to observe an increasing behavior in relation to the interest in the theme. Natural environments were the most researched and change in the land use and occupation of the Amazon Rainforest is still poorly evaluated. Brazil is the country with the highest number of studies, followed by Peru and Colombia. Guyana and Suriname appear as possible scientific gaps and potential environments to be studied. Studies preferentially explore the biomass carbon, with the soil being little evaluated when compared to the total amount of papers found. When observing only the biomass studies, the aboveground biomass is the most evaluated, while the roots and necromass are little studied. The main variables used in biomass equations were diameter at 1.3 m above ground and total tree height. The biomass to carbon conversion factor has been widely used, but it can generate unreliable results. It is recommended to carry out local assessments of the carbon content, especially using the dry combustion method, which generates less waste, with more precise results and shorter execution time of the analyses. Such assessments present values for the location that can avoid false or misinterpretations of the biomass and carbon stocks in the Amazon Rainforest.

    Advances in studies on the plant rhizosphere microorganisms in wetlands: A visualization analysis based on CiteSpace.
    Yaqi Wang, Junhong Bai, Ling Zhang, Haizhu Liu, Wei Wang, Zhe Liu, Guangliang Zhang.
      Rhizosphere microorganisms and their interactions with plants in wetlands have recently attracted much attention due to their importance in enhancing plant environmental adaptation, removing wetland pollutants, and alleviating climate change. However, the fluctuating hydrological environment of wetlands leads to more complex dynamics in the rhizosphere environment. Research progress and hotspots concerning plant-rhizosphere microorganisms under special wetland environments are still kept unclear. To better understand the current research status, hotspots and trends of rhizosphere microorganisms in wetlands, we used CiteSpace bibliometric software to visualize and analyze 231 English-language publications from the Web of Science core collection database. Here, we reviewed the role played by various countries, institutions, and scholars in the studies of plant rhizosphere microorganisms in wetlands based on cooperation network analysis. We discussed the shift from bioremediation and nutrient removal to rhizosphere microbial community composition as a research hotspot for plant rhizosphere microorganisms in wetlands according to keyword co-occurrence and clustering analysis. Finally, we highlighted that more attention should be paid to the ecological functions of rhizosphere microorganisms in different wetland ecosystems, and the plant‒microbe microinterface processes and interaction patterns should be explored in depth to provide new indicators for the evaluation of wetland ecosystem functions.

    The stigmatization of mental illness by mental health professionals: Scoping review and bibliometric analysis.
    Michael Jauch, Stefano Occhipinti, Analise O'Donovan.
      Although research suggests that mental health professionals stigmatize mental illness, studies on this topic are relativity new. Little is known about the state of this research and existing literature reviews exhibit multiple limitations. Accordingly, a scoping review was performed on the endorsed stigmatization of mental illness by mental health professionals, with the aim of exploring how research is conducted and whether there are gaps in the literature. Studies were included from any time period if they supplied findings on the endorsed stigmatization of mental illness by mental health professionals. Research was identified through electronic databases (i.e., PsycINFO, Embase, Medline, Scopus) and other sources (i.e., the Griffith University library, Google Scholar, literature reviews). It was found that the research is characterized by a number of limitations, and little progress has been made in this important domain. Among other limitations, there was a lack of comprehensive studies on the relative stigma of mental illness and how the components of stigmatization relate to each other. A bibliometric analysis also found that a large proportion of the research is not connected by references. Recommendations were made with respect to future research in this area.

    Gender gaps at the academies.
    David Card, Stefano DellaVigna, Patricia Funk, Nagore Iriberri.
      Historically, a large majority of newly elected members of the National Academy of Science (NAS) and the American Academy of Arts and Science (AAAS) were men. Within the past two decades, however, that situation has changed, and in the last 3 y, women made up about 40% of the new members in both academies. We build lists of active scholars from publications in the top journals in three fields-psychology, mathematics, and economics-and develop a series of models to compare changes in the probability of selection of women as members of the NAS and AAAS from the 1960s to today, controlling for publications and citations. In the early years of our sample, women were less likely to be selected as members than men with similar records. By the 1990s, the selection process at both academies was approximately gender neutral, conditional on publications and citations. In the past 20 y, however, a positive preference for female members has emerged and strengthened in all three fields. Currently, women are 3 to 15 times more likely to be selected as members of the AAAS and NAS than men with similar publication and citation records. The positive preference for women may be in part a reflection of concerns that women face higher barriers to publishing in top journals and may receive less credit for their work.

    An Exploratory Study of Medical Journal's Twitter Use: Metadata, Networks, and Content Analyses.
    Donghun Kim, Woojin Jung, Ting Jiang, Yongjun Zhu.
       BACKGROUND: An increasing number of medical journals are using social media to promote themselves and communicate with their readers. However, little is known about how medical journals use Twitter and what their social media management strategies are.
    OBJECTIVE: This study aimed to understand how medical journals use Twitter from a global standpoint. We conducted a broad, in-depth analysis of all the available Twitter accounts of medical journals indexed by major indexing services, with a particular focus on their social networks and content.
    METHODS: The Twitter profiles and metadata of medical journals were analyzed along with the social networks on their Twitter accounts.
    RESULTS: The results showed that overall, publishers used different strategies regarding Twitter adoption, Twitter use patterns, and their subsequent decisions. The following specific findings were noted: journals with Twitter accounts had a significantly higher number of publications and a greater impact than their counterparts; subscription journals had a slightly higher Twitter adoption rate (2%) than open access journals; journals with higher impact had more followers; and prestigious journals rarely followed other lesser-known journals on social media. In addition, an in-depth analysis of 2000 randomly selected tweets from 4 prestigious journals revealed that The Lancet had dedicated considerable effort to communicating with people about health information and fulfilling its social responsibility by organizing committees and activities to engage with a broad range of health-related issues; The New England Journal of Medicine and the Journal of the American Medical Association focused on promoting research articles and attempting to maximize the visibility of their research articles; and the British Medical Journal provided copious amounts of health information and discussed various health-related social problems to increase social awareness of the field of medicine.
    CONCLUSIONS: Our study used various perspectives to investigate how medical journals use Twitter and explored the Twitter management strategies of 4 of the most prestigious journals. Our study provides a detailed understanding of medical journals' use of Twitter from various perspectives and can help publishers, journals, and researchers to better use Twitter for their respective purposes.

    Binary Hydrogels: Induction Methods and Recent Application Progress as Food Matrices for Bioactive Compounds Delivery-A Bibliometric Review.
    Adonis Hilal, Anna Florowska, Małgorzata Wroniak.
      Food hydrogels are biopolymeric materials made from food-grade biopolymers with gelling properties (proteins and polysaccharides) and a 3D network capable of incorporating large amounts of water. They have sparked considerable interest because of their potential and broad application range in the biomedical and pharmaceutical sectors. However, hydrogel research in the field of food science is still limited. This knowledge gap provides numerous opportunities for implementing their unique properties, such as high water-holding capacity, moderated texture, compatibility with other substances, cell biocompatibility, biodegradability, and high resemblance to living tissues, for the development of novel, functional food matrices. For that reason, this article includes a bibliometric analysis characterizing research trends in food protein-polysaccharide hydrogels (over the last ten years). Additionally, it characterizes the most recent developments in hydrogel induction methods and the most recent application progress of hydrogels as food matrices as carriers for the targeted delivery of bioactive compounds. Finally, this article provides a future perspective on the need to evaluate the feasibility of using plant-based proteins and polysaccharides to develop food matrices that protect nutrients, including bioactive substances, throughout processing, storage, and digestion until they reach the specific targeted area of the digestive system.

    The Association Between Orthopaedic Surgeon Academic Productivity Metrics and Compensation from Medical Industry.
    Christopher D Flanagan, Francis T Walson, Christian M Schmidt, Mark A Frankle, Hassan R Mir.
       INTRODUCTION: Academic research has value well beyond personal financial gain. However, these endeavors do require a notable amount of time and opportunity cost. Academic productivity may raise a researcher's profile within the field, increasing the likelihood for interactions with the medical industry and possibly cultivating relationships with future monetary significance.
    METHODS: Queries of the Centers for Medicaid and Medicare Services publicly available Open Payments System allowed for extraction of industry compensation data for orthopaedic surgeons. Aggregate data produce three compensation groups (mean annual income) for individual physicians: none; 1 to $100,000; and >$100,000. Physicians in the highest income category were matched 1:1 with physicians in each of the other two compensation groups. Selected physicians then underwent an academic productivity assessment. Queries of Web of Science, Scopus, and Google Scholar User Profile databases provided the h-index and m-index for each surgeon. Bivariate and multivariate analyses produced statistical results. In addition to the analysis of the tiered income groups, analysis of compensation as a continuous variable also occurred.
    RESULTS: From 2016 to 2020, 636, 7,617, and 22,091 US orthopaedic surgeons earned mean annual industry compensation >$100,000; between $1 and $100,000; and $0, respectively. Royalties (80.8%) predominated in the top earning group, compared with Consulting Fees (46.5%) in the second-tier group. The highest income group had higher h-index ($0 versus $1 to 100,000 versus >$100,000 = 3.6 versus 7.5 versus 20.0, P < 0.001) and m-index ($0 versus $1 to 100,000 versus >$100,000 = 0.26 versus 0.44 versus 0.80, P < 0.001) scores than either the intermediate or no compensation groups. In addition, h-index and m-index correlated positively with total compensation (h-index: r = 0.32, P < 0.001; m-index: r = 0.20, P < 0.001). Multivariable analysis of factors associated with increased industry compensation identified h-index (B = 0.034, P < 0.001) and years active (B = 0.042, P < 0.001) as having significant associations with physician compensation. Physician subspecialty also correlated with industry compensation.
    DISCUSSION: Academic research can provide invaluable contributions to the improvement of patient care. These efforts often require notable personal sacrifice with minimal direct remuneration. However, academic productivity metrics correlate positively with industry compensation, highlighting a possible supplementary benefit to scholarly efforts.

    Gender inequality and self-publication are common among academic editors.
    Fengyuan Liu, Petter Holme, Matteo Chiesa, Bedoor AlShebli, Talal Rahwan.
      Scientific editors shape the content of academic journals and set standards for their fields. Yet, the degree to which the gender makeup of editors reflects that of scientists, and the rate at which editors publish in their own journals, are not entirely understood. Here, we use algorithmic tools to infer the gender of 81,000 editors serving more than 1,000 journals and 15 disciplines over five decades. Only 26% of authors in our dataset are women, and we find even fewer women among editors (14%) and editors-in-chief (8%). Career length explains the gender gap among editors, but not editors-in-chief. Moreover, by analysing the publication records of 20,000 editors, we find that 12% publish at least one-fifth, and 6% publish at least one-third, of their papers in the journal they edit. Editors-in-chief tend to self-publish at a higher rate. Finally, compared with women, men have a higher increase in the rate at which they publish in a journal soon after becoming its editor.
