    The open access advantage for studies of human electrophysiology: Impact on citations and Altmetrics.
    Peter E Clayson, Scott A Baldwin, Michael J Larson.
      Barriers to accessing scientific findings contribute to knowledge inequalities based on financial resources and decrease the transparency and rigor of scientific research. Recent initiatives aim to improve access to research as well as methodological rigor via transparency and openness. We sought to determine the impact of such initiatives on open access publishing in the sub-area of human electrophysiology and the impact of open access on the attention articles received in the scholarly literature and other outlets. Data for 35,144 articles across 967 journals from the last 20 years were examined. Approximately 35% of articles were open access, and the rate of publication of open-access articles increased over time. Open access articles showed 9 to 21% more PubMed and CrossRef citations and 39% more Altmetric mentions than closed access articles. Green open access articles (i.e., author archived) did not differ from non-green open access articles (i.e., publisher archived) with respect to citations and were related to higher Altmetric mentions. These findings demonstrate that open-access publishing is increasing in popularity in the sub-area of human electrophysiology and that open-access articles enjoy the "open access advantage" in citations similar to the larger scientific literature. The benefit of the open access advantage may motivate researchers to make their publications open access and pursue publication outlets that support it. In consideration of the direct connection between citations and journal impact factor, journal editors may improve the accessibility and impact of published articles by encouraging authors to self-archive manuscripts on preprint servers.

    Bibliometric analysis of the top 100 cited articles in head and neck radiology.
    Aye Mm Oo, Timothy Sm ChuT.
      Background: Bibliometric analysis is commonly used to identify influential research within a given topic.Purpose: To identify the 100 top-cited articles in head and neck radiology, analyse the history and trends in head and neck imaging research, and understand what constitutes a highly cited work.
    Material and Methods: A literature search was performed on the Thomson Reuters Web of Science using pre-defined search terms. The results were ranked according to citation count and screened to create a single database. The information included in the database were: Web of Science citations, year published, first author, primary institution, country of origin, journal, journal impact factor, title, study design, study focus and modality.
    Results: 24,664 eligible papers were returned. Citations for the 100 top-cited articles ranged from 115 to 1185, and citations per year ranged from 3.5 to 197.5. More than half of the articles were published in the 2000s (n = 67). Radiology has the greatest number of publications (n = 22), followed by Journal of Nuclear Medicine (n = 14). Positron Emission Tomography (n = 56) was the most commonly studied modality, followed by Magnetic Resonance (n = 40) and Computed Tomography (n = 31). The most common topics of publication were diagnosis (n = 63), followed by prognosis (n = 16).
    Conclusion: This study provides insights into the most influential research in head and neck radiology in the current time. It also serves as a guide to the characteristics of a highly cited work in this field.

    The Top 100 Most Cited Articles Published in Dentistry: 2020 Update.
    Faris Yahya Asiri, Estie Kruger, Marc Tennant.
      This bibliometric review is aimed to analyze the top 100 most-cited publications in dentistry and to compare its outcomes. A literature search was performed using Elsevier's Scopus, without any restriction of language, publication year, or study design. Of 336,381 articles, the top 100 were included based on their citation count, which ranged from 638 to 4728 citations (Feijoo et al., 326 to 2050). The most productive decade was the 2000s, with 40 articles on the list (Feijoo et al., 1980s: 26). Marx RE (7%) was the major contributor in this study (Feijoo et al., Socransky SS: 9%), and almost half (48%) of articles were from the USA. Of the top 100 articles, 26% focused on periodontology (Feijoo et al., periodontology: 43%), while 17% of the total were published in the Journal of Dental Research (Feijoo et al., Journal of Clinical Periodontology: 20%). Most of the publications were narrative reviews/expert opinion (36%), (Feijoo et al., case series: 22%), and were within the evidence level V (64%) (Feijoo et al., 54%). The citation count that a paper secures is not necessarily a reflection of research's quality, however, the current analysis provides the latest citation trends in dentistry.

    Ankylosing spondylitis rehabilitation publications and the global productivity: a Web of Science-based bibliometric analysis (2000-2019).
    Ahmet Akyol, Burhan Fatih Kocyigit.
      Rehabilitation programs have an important place in the treatment of ankylosing spondylitis (AS), but there is no comprehensive bibliometric research that assesses publications on AS rehabilitation in a holistic way. The aim of this study was to investigate the quantity and quality of articles related to AS rehabilitation and to reveal the features of global productivity in this topic. This bibliometric study was conducted utilizing the Web of Science (WoS) database with the keywords 'ankylosing spondylitis rehabilitation', 'ankylosing spondylitis exercise', 'ankylosing spondylitis physical therapy' and 'ankylosing spondylitis physiotherapy'. The number of articles, citations, and main active countries were determined and trend analyses were performed. A total of 792 articles were reviewed. The articles originated from 51 different countries, 22 of which met the main active country criteria. A significant increase trend was detected in the number of articles between 2000 and 2019 (p < 0.001). The five most productive countries were Germany (n = 111; 14.02%), Turkey (n = 98; 12.37%), the United States (n = 71; 8.96%), the United Kingdom (n = 53; 6.69%) and the Netherlands (n = 53; 6.69%). The highest values in number of articles per million population were calculated in Norway, the Netherlands and Austria, respectively. In the analysis according to GDP, Norway, the Netherlands and Turkey were ranked as the first three. The top three countries for the average citation count were France, Netherlands and Germany. This bibliometric study can be considered as an assessment and summary of worldwide scientific production on AS rehabilitation. The data demonstrate an increasing trend in research productivity since 2000. European countries were seen to be at the forefront both quantitatively and qualitatively in this area.

      OBJECTIVE: The steady and continued increase of the Journal of Oral Pathology & Medicine's (JOPM) popularity, prompted a bibliometric analysis of the journal. The purpose was to assess the significance and effect of the published research articles in the Journal from 1972 - 2020, aiding the identification of landmark articles. We performed a bibliometric analysis using the top 100 cited papers in the Journal of Oral Pathology & Medicine.MATERIALS AND METHODS: An extensive review of the Web of Science was undertaken. Standard information such as author details, affiliated institutions, publication year, and the country of origin was recorded.
    RESULTS: The top 100 cited articles in JOPM were assessed. The maximum and minimum number of citations in the top 100 articles was 1,459 and 95 respectively. A total of 16,790 citations were recorded for these 100 aricles. Authors were affiliated to 28 different countries, 17 research articles from the UK and 12 from the USA. Other countries furnished seven or fewer articles.
    CONCLUSION: This bibliometric analysis provides a synopsis of research published in the journal over a 48 year period. Recent interest in the journal shows a healthy increase in submissions and profile.

    The 100 Most-cited Articles in Abdominoplasty: A Bibliometric Analysis.
    Ankur Khajuria, Walton N Charles, Atul Dutt, Alfredo Hoyos.
      Abdominoplasty is one of the most common aesthetic procedures performed globally. Research in this field is evolving, with recent emphasis on evidence-based surgery optimizing informed consent. This bibliometric analysis aimed to characterize emerging research trends and to assess the methodological quality of the highest impact abdominoplasty research.Methods: The 100 most-cited articles in abdominoplasty were identified on Web of Science, across all available journals and years (1950-2019). Study details, including the citation count, main subject, and outcome measures, were extracted from each article by 2 independent reviewers. The level of evidence of each study was also assessed.
    Results: The 100 most-cited articles in abdominoplasty were cited by a total of 2545 articles. Citations per article ranged from 206 to 34 (mean 65). Overall, 50 articles were assessed to be level of evidence 3, which is representative of the large number of cohort studies (n = 59) on the list. Similar numbers achieved levels 2, 4, and 5 (n = 16, 20, and 14), though none reached level 1. The main subject was operative technique in 50 articles, followed by outcomes in 34 articles. Only 7 articles utilized objective cosmetic outcome measures. Patient-reported outcome measures were employed in 25 articles, though only 5 incorporated validated questionnaires.
    Conclusions: The most-cited research in abdominoplasty largely comprised low-to-moderate quality studies, with no article achieving the highest level of evidence. Contemporary high-quality evidence incorporating validated outcome measures is crucial to enhance shared decision-making, particularly in aesthetic procedures.

    Trends of the main bibliometric indicators of Anais Brasileiros de Dermatologia (2010-2019).
    Hélio Amante Miot, Mayra Ianhez, Paulo Müller Ramos.
      BACKGROUND: The Anais Brasileiros de Dermatologia (Anais Brasileiros de Dermatologia) is the official journal of the Brazilian Society of Dermatology, which has been published since 1925, with free, bilingual access. There are several bibliometric indicators that estimate aspects of a journal's scientific influence. Its analysis, based especially on the evolutionary trend, allows identifying the journal's strengths and weaknesses, in addition to guiding editorial policies.OBJECTIVES: To evaluate the trends of the main bibliometric indicators of Anais Brasileiros de Dermatologia, in the decade of 2010-2019.
    METHODS: Methodological study that proposed the analysis of bibliometric indicators published by Journal Citation Reports, SCImago, and Scopus, for the journal Anais Brasileiros de Dermatologia, from 2010 to 2019. The following aspects were evaluated: Impact factor, Immediacy index, SJR (SCImago), in addition to the number of citations, citable items, Cite Score, percentage of external citations, percentage of cited articles, percentage of citable articles, and the article influence score.
    RESULTS: There was an increase in the main bibliometric indicators in the last decade: impact factor (0.337 to 1.121), immediacy index (0.054 to 0.204),Eigenfactor (0.00025 to 0.00394), SJR (0.176 to 0.453). The percentage of external citations (48.4% to 94.1%) and cited articles (24.7% to 51.4%) also increased. The increase in the impact factors of Anais Brasileiros de Dermatologia in the period was more significant than that of the dermatology journals (1,667 to 2,118) and the Brazilian journals (1,247 to 1,408), indexed in the Journal Citation Reports.
    STUDY LIMITATIONS: Failure in the classification and registration of the databases.
    CONCLUSIONS: There has been a consistent increase in the scientific influence of Anais Brasileiros de Dermatologia in the last decade.

    A bibliometric analysis of segmentectomy versus lobectomy for non-small cell lung cancer research (1992-2019).
    Zhiyun Xu, Xiang Gao, Binhui Ren, Shuai Zhang, Lin Xu.
      BACKGROUND: This study intends to create a series of scientific maps to quantitatively estimate hot spots and emerging trends in segmentectomy versus lobectomy for non-small cell lung cancer (NSCLC) research with bibliometric methods.METHODS: Articles published on segmentectomy versus lobectomy for NSCLC were extracted from the Web of Science Core Collection (WoSCC). Extracted information was analyzed quantitatively using bibliometric analysis by CiteSpace to find hot spots and frontiers in this research area.
    RESULTS: A total of 362 scientific articles on segmentectomy versus lobectomy for NSCLC were collected, and the annual publication rate increased over time from 1992 to 2019. The leading country and the leading institution were the United States and University of Pittsburgh, respectively. Furthermore, the most prolific researchers were, namely, James D. Luketich, Rodney J. Landreneau, Matthew J. Schuchert, Morihito Okada, and David O. Wilson. The analysis of keywords pointed out that carcinoma, bronchogenic carcinoma, limited resection, segmental resection, and morbidity are hot spots and lymph node dissection, minimally invasive surgery, impact, epidemiology, and high risk are research frontiers in this field.
    CONCLUSION: Publications related to segmentectomy versus lobectomy for NSCLC have made great achievements based on bibliometric analysis in recent years. However, further research and global collaboration are still required. Finally, we find that segmentectomy for the treatment of NSCLC is receiving much more attention from researchers globally compared with lobectomy in this research area.

    Konstantinos I Bougioukas, Elpida Vounzoulaki, Chrysanthi D Mantsiou, Georgia D Papanastasiou, Eliophotos D Savvides, Evangelia E Ntzani, Anna-Bettina Haidich.
      OBJECTIVE: To conduct a bibliometric analysis using a large sample of overviews of systematic reviews (OoSRs) and reveal research trends and areas of interest about these studies.STUDY DESIGN AND SETTING: We searched MEDLINE, Scopus and Cochrane Database of Systematic Reviews from 1/1/2000 to 15/10/2020. We used Scopus meta-data and two authors recorded supplementary information independently. We summarized the data using frequencies with percentages.
    RESULTS: A total of 1558 studies were considered eligible for analysis. We found that the publications have been increasing yearly and their nomenclature was not uniform (the most frequent label in the title was "overview of systematic reviews"). The largest number of papers and the most cited ones were published by corresponding authors from the UK. The publications were distributed across 737 scholarly journals and many of them were published in the field of complementary/alternative medicine, psychiatry/psychology, nutrition/dietetics, and pediatrics. The co-authorship analysis revealed collaborations among countries. The most common clinical conditions were depression, diabetes, cancer, dementia, pain, cardiovascular disease, stroke, obesity, and schizophrenia.
    CONCLUSION: OoSRs have recently become a popular approach of evidence synthesis. International collaborations between overview authors from countries with increased research productivity and countries with less research activity should be encouraged.

    Increases in female academic productivity and female mentorship highlight sustained progress in previously identified neurosurgical gender disparities.
    Birra Taha, Praneeth Sadda, Graham Winston, Eseosa Odigie, Cristina Londono, Jeffrey P Greenfield, Susan C Pannullo, Caitlin Hoffman.
      OBJECTIVE: A meta-analysis was performed to understand disparities in the representation of female authorship within the neurosurgical literature and implications for career advancement of women in neurosurgery.METHODS: Author names for articles published in 16 of the top neurosurgical journals from 2002 to 2019 were obtained from MEDLINE. The gender of each author was determined using automated prediction methods. Publication trends were compared over time and across subdisciplines. Female authorship was also compared to the proportionate composition of women in the field over time.
    RESULTS: The metadata obtained from 16 major neurosurgical journals yielded 66,546 research articles. Gender was successfully determined for 96% (127,809/133,578) of first and senior authors, while the remainder (3.9%) were unable to be determined through prediction methods. Across all years, 13.3% (8826) of articles had female first authorship and 9.1% (6073) had female senior authorship. Female first authorship increased significantly over time from 5.8% in 2002 to 17.2% in 2019 (p < 0.001). Female senior authorship also increased significantly over time, from 5.5% in 2002 to 12.0% in 2019 (p < 0.001). The journals with the highest proportions of female first authors and senior authors were the Journal of Neurosurgery: Pediatrics (33.5%) and the Asian Journal of Neurosurgery (23.8%), respectively. Operative Neurosurgery had the lowest fraction of female first (12.4%) and senior (4.7%) authors. There was a significant difference between the year-by-year proportion of female neurosurgical trainees and the year-by-year proportion of female neurosurgical first (p < 0.001) and senior (p < 0.001) authors. Articles were also more likely to have a female first author if the senior author of the article was female (OR 2.69, CI 2.52-2.86; p < 0.001). From 1944 to 2019, the Journal of Neurosurgery showed a steady increase in female first and senior authorship, with a plateau beginning in the 1990s.
    CONCLUSIONS: Large meta-analysis techniques have the potential to effectively leverage large amounts of bibliometric data to quantify the representation of female authorship in the neurosurgical literature. The proportion of female authors in major neurosurgical journals has steadily increased. However, the rate of increase in female senior authorship has lagged behind the rate of increase in first authorship, indicating a disparity in academic advancement in women in neurosurgery.

    A comparative bibliometric analysis of Chinese and foreign articles in environmental footprint family (EFF) research.
    Yezhu Wang, Yundong Xie, Rongting Zhou, Xiaoli Hu, Xingchen Li.
      Research on environmental footprint family (EFF), including these studies of environmental footprints and footprint family, has been widely applied to environmental impact assessment and sustainability evaluation. Although some bibliometric studies have focused on footprint indicators, there is still the lack of the contrast of Chinese and foreign literature in the field of EFF and the conclusions of successful practices at home and abroad in recent years. Unlike most previous papers, we improve the search strategy for collecting accurate documents data and compare China and foreign from a unified international perspective. Two datasets covering 1103 Chinese and 6011 foreign articles between 1996 and 2019 were collected to compare their bibliometric differences in EFF research. We not only comparatively investigate the overview of Chinese and foreign articles in EFF field based on the objects of publications, journals, authors, and institutions, but also explore their differences in the conceptual and intellectual structure from the aspects of keywords and citation analysis. For example, we can deduce that Chinese articles tend to engage in applied research and lack of theoretical innovations and breakthroughs in this field. Our comparative research results are useful and helpful for the public, policymakers, and researchers in this filed.

    Trends in the Use of Sphingosine 1 Phosphate in Age-Related Diseases: A Scientometric Research Study (1992-2020).
    Qiong He, Gaofeng Ding, Mengyuan Zhang, Peng Nie, Jing Yang, Dong Liang, Jiaqi Bo, Yi Zhang, Yunfeng Liu.
      Objectives: This study was designed to explore the intellectual landscape of research into the application of sphingosine 1 phosphate (S1P) in age-related diseases and to identify thematic development trends and research frontiers in this area.Methods: Scientometric research was conducted by analyzing bibliographic records retrieved from the Web of Science (WOS) Sci-Expanded Database dated between 1900 and 2020. Countries, institutions, authors, keyword occurrence analysis, and cooperation network analysis were performed using the CiteSpace and VOSviewer software.
    Results: A total of 348 valid records were included in the final dataset, and the number of publications and the frequency of citations have grown rapidly over the last ten years. The USA (n = 175), China (n = 42), and Germany (n = 37) were the three largest contributors to the global publications on S1P and aging, while the Medical University of South Carolina (n = 15), University of California, San Francisco (n = 13), and University of Toronto (n = 13) were the leading institutions in this field. Analysis showed that early studies primarily focused on the mechanism of S1P intervention in AD. While S1P and its relevant metabolites have remained a long-term active area of research, recent studies have focused more on interventions aimed at improving retinal degeneration, cardiomyopathy, multiple sclerosis, and diabetes, among others.
    Conclusions: It is worth mentioning that this manuscript is the first to describe any bibliometric analysis of S1P and its application in age-related interventions. This study includes a discussion of the (1) historical overview of the topic; (2) main contributors: journals, countries, institutes, funding agencies, and authors; (3) collaboration between institutes and authors; (4) research hot spots and zones; and 5) research trends and frontiers. This will enable scholars to understand the current status of S1P research in age-related diseases.

    The 100 Most-disruptive Articles in Plastic and Reconstructive Surgery and Sub-specialties (1954-2014).
    Marek A Hansdorfer, Sydney R Horen, Brandon E Alba, Jennifer N Akin, Amir H Dorafshar, Adan Z Becerra.
      Alternative bibliometrics have recently been the subject of significantly increased interest. The disruption index is a new bibliometric that was recently applied to surgery and urology and identifies papers that shift paradigms and eclipse previous research in a given field.Methods: The 100 most-disruptive publications in the 14 most prominent plastic and reconstructive surgery and subspecialty journals were identified.
    Results: We present the 100 most-disruptive studies as well as the 100 most-cited studies for comparison in n=14 of the most popular plastic and reconstructive surgery (and subspecialty) journals between 1954 and 2014. The 100 most-disruptive publications in these journals were more disruptive than 99.8% of all PubMed papers. Plastic and Reconstructive Surgery (PRS) had the most papers in the top 100 (n=64) followed by British Journal of Plastic Surgery (currently Journal of Plastic, Reconstructive & Aesthetic Surgery, n=15), and Journal of Oral and Maxillofacial Surgery (n=7). PRS had 9 of the top 10 papers. However, Clinics in Plastic Surgery had the highest average disruption score for all its published papers (0.0029). The correlation coefficient linking disruption scores and citation counts was 0.01 and 0.11, respectively. The most common decade represented in the top 100 was the 1980's (n=31) and the least common was the 2000's (n=9).
    Conclusions: This is the first application of the disruption index to plastic and reconstructive surgery. The disruption score provides a unique ability to identify research that has shifted paradigms and driven the innovation that defines our specialty.

    Use of the journal impact factor for assessing individual articles need not be statistically wrong.
    Ludo Waltman, Vincent A Traag.
      Most scientometricians reject the use of the journal impact factor for assessing individual articles and their authors. The well-known San Francisco Declaration on Research Assessment also strongly objects against this way of using the impact factor. Arguments against the use of the impact factor at the level of individual articles are often based on statistical considerations. The skewness of journal citation distributions typically plays a central role in these arguments. We present a theoretical analysis of statistical arguments against the use of the impact factor at the level of individual articles. Our analysis shows that these arguments do not support the conclusion that the impact factor should not be used for assessing individual articles. In fact, our computer simulations demonstrate the possibility that the impact factor is a more accurate indicator of the value of an article than the number of citations the article has received. It is important to critically discuss the dominant role of the impact factor in research evaluations, but the discussion should not be based on misplaced statistical arguments. Instead, the primary focus should be on the socio-technical implications of the use of the impact factor.

    Research on neck dissection for oral squamous-cell carcinoma: a bibliometric analysis.
    Zhou Jiang, Chenzhou Wu, Shoushan Hu, Nailin Liao, Yingzhao Huang, Haoran Ding, Ruohan Li, Yi Li.
      Neck dissection for oral squamous-cell carcinoma (OSCC) is a clinically controversial issue and has therefore been the subject of abundant research. However, no one has performed a bibliometric study on this topic to date. The aim of this study was to assess the development of research on neck dissection for OSCC in terms of the historical evolution, current hotspots and future directions, particularly including research trends and frontiers from 2010 to 2019. Literature records related to research on neck dissection for OSCC were retrieved from the Web of Science Core Collection (WoSCC). CiteSpace was used as a tool to perform a bibliometric analysis of this topic. The survey included 2 096 papers. "Otorhinolaryngology" was the most popular research area. The most active institutions and countries were Memorial Sloan Kettering Cancer Center and the USA, respectively. Shah J.P. was the most cited author. Among the six identified "core journals", Head & Neck ranked first. The top three trending keywords were 'invasion', 'upper aerodigestive' and 'negative neck'. 'D'Cruz AK (2015)' was the most cited and the strongest burst reference in the last decade. The study evaluated the effect on survival of elective versus therapeutic neck dissection in patients with lateralized early-stage OSCC. The depth of invasion and the management of N0 OSCC were research frontiers in this field. The present study provides a comprehensive bibliometric analysis of research on neck dissection for OSCC, which will assist investigators in exploring potential research directions.

    A Bibliometric and Citation Network Analysis of Myopia Genetics.
    Cristina Alvarez-Peregrina, Clara Martinez-Perez, Cesar Villa-Collar, Miguel Ángel Sánchez-Tena.
      BACKGROUND: To aim of the study was describe the growth of publications on genetic myopia and understand the current research landscape through the analysis of citation networks, as well as determining the different research areas and the most cited publications.METHODS: The Web of Science database was used to perform the publication search, looking for the terms "genetic*" AND "myopia" within the period between 2009 and October 2020. The CitNetExplorer and CiteSpace software were then used to conduct the publication analysis. To obtain the graphics, the VOSviewer software was used.
    RESULTS: A total of 721 publications were found with 2999 citations generated within the network. The year 2019 was singled out as a "key year", taking into account the number of publications that emerged in that year and given that in 2019, 200 loci associated with refractive errors and myopia were found, which is considered to be great progress. The most widely cited publication was "Genome-wide meta-analyses of multiancestry cohorts identify multiple new susceptibility loci for refractive error and myopia", an article by Verhoeven et al., which was published in 2013. By using the clustering function, we were able to establish three groups that encompassed the different research areas within this field: heritability rate of myopia and its possible association with environmental factors, retinal syndromes associated with myopia and the genetic factors that control and influence axial growth of the eye.
    CONCLUSIONS: The citation network offers a comprehensive and objective analysis of the main papers that address genetic myopia.

    Ana Belén Barragán Martín, María Del Mar Molero Jurado, María Del Carmen Pérez-Fuentes, María Del Mar Simón Márquez, África Martos Martínez, Maria Sisto, José Jesús Gázquez Linares.
      In recent years, cyberbullying has been recognized as a severe public health problem and is drawing growing interest. The objective of this study was to perform a bibliometric analysis of the scientific production on adolescent cyberbullying in the last decade. A search for publications was made in the Web of Science database, where the 1530 documents identified were analyzed with BibExcel software and visualized using the Pajek and VOSviewer tools. The predominant language in the publications was English, followed by Spanish. The publication rate was shown to have increased in recent years. The journal "Computers in Human Behavior" had the highest production. The repercussion of new technologies on this phenomenon has been felt, and research groups have enlarged their production in response to the problem. A systematic review and/or meta-analysis examining the contents of the studies identified and the variables related to this problem is therefore necessary. This could identify a point of reference for research in this field and a basis for future reviews of its development and progress over time.

    [Bibliometric analysis of refractory facial paralysis based on CNKI database].
    Ying Han, Ren Liu, Tuo-Ran Wang, Yue Jiao, Jin Huo, Ying-Ying Wang, Wen-Yan Wang, Shun-Yue Li, Jin-Hong Yang.
      The current development situation and the hotspot of the relevant research on refractory facial paralysis are explored. The articles on refractory facial paralysis are retrieved from CNKI database. The bibliographic items co-occurrence matrix builder (BICOMB) 2.0 is adopted to extract and analyze statistically literature characteristics and generate the high-frequency keywords matrix. The graphical clustering toolkit (gCLUTO) 1.0 is used to cluster the high-frequency keywords. A total of 750 articles are included, mostly published in Journal of Clinical Acupuncture and Moxibustion (63 articles), Chinese Acupuncture & Moxibustion (54 articles) and Shanghai Journal of Acupuncture and Moxibustion (27 articles) separately. The number of published articles by the active first authors are accounted for 10.1% of the total. When the high-frequency keywords are clustered into 4 categories, the topics with good cluster effect including the inheritance of the experiences of famous doctors in the comprehensive treatment of refractory facial paralysis, the comprehensive treatment measures with the a quite high curative effect on refractory facial paralysis based on heat-sensitive moxibustion and those based on the intervention by enhancing acupoint stimulation effect, as well as the study on the comprehensive treatment measures. General speaking, the regimen of acupuncture and moxibustion is a hotspot in the study on refractory facial paralysis. Research fellows give the consideration on the inheritance of the experiences of famous doctors, adopt the comprehensive treatment methods and enhance the actions of "warming" and "promoting" in the regimen by focusing on the pathogenesis. Such an idea has certain enlightening role to the study on the treatment of refractory diseases.

    Knowledge Dissemination by the Naturopathic Profession: A Bibliometric Analysis of Naturopath-Authored, Peer-Reviewed Publications.
    Amie Steel, Hope Foley, Jasmine D'Souza, Jon Adams, Jon Wardle.
      Objectives: This study aims to describe the characteristics of published peer-reviewed journal articles authored by naturopathic practitioners (NPs) Design: The study used bibliometric analysis of data extracted from journal articles. Settings/Location: International Subjects: Articles were included if they had at least one author with a naturopathic qualification and were published in a peer-reviewed, indexed journal. Data collection: A snowballing method was used between June 2018 and July 2019 to identify relevant articles. Outcome measures: Data related to geography, affiliation, year of publication, article type or research design, article topic, and journal were extracted from each included article. Results: Identified articles (n = 2,218) were published by NP from 22 countries between 1987 and 2019, with 80.9% published in the last 10 years. Most articles were published by NP from the America (52.5%) and Western Pacific (28.3%) World Health Organization regions. The most common type of study design or article type was reviews and meta-analyses (23.2%) and clinical trials or intervention studies (19.4%). Explicit mention of naturopathy was reported in 8.1% of articles. Almost half (48.4%) of all included articles were published in 40 journals, and 56.9% of these were published in journals ranked in the first quartile of at least one subject area. Articles focused on mental health were more likely to be conducted in Australia (odds ratio [OR] 3.3) and focused on lifestyle behavior (OR 2.5) or clinical nutrition (OR 1.6). Articles about cancer or cancer-related conditions were more likely to include lifestyle behavior (OR 2.0) and less likely to be conducted in Australia (OR 0.1) or Germany (OR 0.5). Conclusions: The international naturopathy research community has produced peer-reviewed literature for over 30 years and has demonstrated sustained commitment to codifying existing knowledge, generating new knowledge, and disseminating this knowledge to the wider clinical and research community.

    Women's role in neurosurgical research: is the gender gap improving?
    Marta Pastor-Cabeza, Ramon Torné, Roser García-Armengol, Belén Menéndez-Osorio, Alejandra Mosteiro-Cadaval, Alicia Bollar, Jordi M Rimbau, Rosario Sarabia, Ana Rodríguez-Hernández.
      OBJECTIVE: The percentage of women publishing high-impact neurosurgical research might be perceived as a representation of our specialty and may influence the perpetuation of the existing gender gap. This study investigated whether the trend in women taking lead roles in neurosurgical research has mirrored the increase in female neurosurgeons during the past decade and whether our most prestigious publications portray enough female role models to stimulate gender diversity among the new generation of neurosurgeons.METHODS: Two of the most prominent neurosurgical journals-Journal of Neurosurgery and Neurosurgery-were selected for this study, and every original article that was published in 2009 and 2019 in each of those journals was investigated according to the gender of the first and senior authors, their academic titles, their affiliations, and their institutions' region.
    RESULTS: A total of 1328 articles were analyzed. The percentage of female authors was significantly higher in Europe and Russia compared with the US and Canada (first authors: 60/302 [19.9%] vs 109/829 [13.1%], p = 0.005; and senior authors: 32/302 [10.6%] vs 57/829 [6.9%], p = 0.040). Significantly increased female authorship was observed from 2009 to 2019, and overall numbers of both first and senior female authors almost doubled. However, when analyzing by regions, female authorship increased significantly only in the US and Canada. Female authors of neurosurgical research articles were significantly less likely to hold an MD degree compared with men. Female neurosurgeons serving as senior authors were represented in only 3.6% (48/1328) of articles. Women serving as senior authors were more likely to have a female colleague listed as the first author of their research (29/97 [29.9%] vs 155/1231 [12.6%]; χ2 = 22.561, p = 0.001).
    CONCLUSIONS: Although this work showed an encouraging increase in the number of women publishing high-impact neurosurgical research, the stagnant trend in Europe may suggest that a glass ceiling has been reached and further advances in equity would require more aggressive measures. The differences in the researchers' profiles (academic title and affiliation) suggest an even wider gender gap. Cultural unconscious bias may explain why female senior authors have more than double the number of women serving as their junior authors compared with men. While changes in the workforce happen, strategies such as publishing specific issues on women, encouraging female editorials, and working toward more gender-balanced editorial boards may help our journals to portray a more equitable specialty that would not discourage bright female candidates.

    Visual Analysis of the External Characteristics and Research Hotspots of Literatures in International Forensic Science.
    H X Liu, T T Yang, S Z Huang, J Zhang, D Zhao, L Liu.
      Abstract: Objective To analyze the forensic science-related literature included in the Web of Science database in the recent decade through bibliometric methods, to provide reference for relevant research. Methods Literatures were searched in 3 ways： Subject search, Journal search and Institution search. The annual distribution, national （regional） distribution, institution distribution, journal distribution and the research hotspots of the related literatures were analyzed through Thomson Data Analyzer （TDA）, Ucinet, VOSviewer, and so on. Results A total of 49 469 related literatures were included in the recent decade. The number of literatures continued to climb year by year. The top 15 countries （regions） accounted for 78.52% of the total number of published literatures, and China ranked 5th, but ranked 12th in terms of the proportion of high-cited papers; Netherlands, Switzerland, Australia, etc. had high comprehensive influence. The number of countries （regions） that cooperated with China were 129, including the United States, the United Kingdom and Germany. The Institute of Forensic Science of Saint Mary's University, University of Sydney and Netherlands Forensic Institute had high comprehensive influence, and the related literatures were published on 6 357 journals. According to high-frequency co-occurrence network and high-cited papers, brain injury, health policy, assessment scales and models and medical imaging were selected as research hotspots. Conclusion The total number of literatures in forensic science included in international SCI increased significantly, and the influence of China's achievements needs to be greatly enhanced; the research institutions were scattered, and China's research power needs to be continuously condensed; the research hotspots in international fields are extensive, and the international participation of China in top level research needs to be strengthened.

    Miguel Ángel Sánchez-Tena, Clara Martinez-Perez, Cesar Villa-Collar, Cristina Alvarez-Peregrina.
      BACKGROUND: The main objective of this study was to use citation networks to analyze the relationship between different publications on the impact of COVID-19 at an ocular level and their authors. Furthermore, the different research areas will be identified, and the most cited publication will be determined.MATERIALS AND METHODS: The publications were searched within the Web of Science database, using "ocular", "SARS-CoV-2", "ophthalmology", "eyesight", and "COVID-19" as keywords for the period between January 2020 and January 2021. The Citation Network Explorer and the CiteSpace software were used to analyze the different publications.
    RESULTS: A total of 389 publications with 890 citations generated on the web were found. It must be highlighted that July was the month with the largest number of publications. The most cited ones were "Characteristics of Ocular Findings of Patients with Coronavirus Disease 2019 (COVID-19) in Hubei Province, China" by Wu et al., which was published in May 2020. Three groups covering the different research areas in this field were found using the clustering functions: ocular manifestations, teleophthalmology, and personal protective equipment.
    CONCLUSIONS: The citation network has shown a comprehensive and objective analysis of the main studies on the impact of COVID-19 in ocular disease.

    Characterizing research leadership on geographically weighted collaboration network.
    Chaocheng He, Jiang Wu, Qingpeng Zhang.
      Research collaborations, especially long-distance and international collaborations, have become increasingly prevalent worldwide. Recent studies highlighted the significant role of research leadership in collaborations. However, existing measures of the research leadership do not take into account the intensity of leadership in the co-authorship network. More importantly, the spatial features, which influence the collaboration patterns and research outcomes, have not been incorporated in measuring the research leadership. To fill the gap, we construct an institution-level weighted co-authorship network that integrates two types of weight on the edges: the intensity of collaborations and the spatial score (the geographical distance adjusted by the cross-linguistic-border nature). Based on this network, we propose a novel metric, namely the spatial research leadership rank, to identify the leading institutions while considering both the collaboration intensity and the spatial features. The leadership of an institution is measured by the following three criteria: (a) the institution frequently plays the corresponding rule in papers with other institutions; (b) the institution frequently plays the corresponding rule in longer distance and even cross-linguistic-border collaborations; (c) the participating institutions led by the institution have high leadership status themselves. Harnessing a dataset of 323,146 journal publications in pharmaceutical sciences during 2010-2018, we perform a comprehensive analysis of the geographical distribution and dynamic patterns of research leadership flows at the institution level. The results demonstrate that the SpatialLeaderRank outperforms baseline metrics in predicting the scholarly impact of institutions. And the result remains robust in the field of Information Science and Library Science.Supplementary Information: The online version contains supplementary material available at 10.1007/s11192-021-03943-w.

    A bibliometric analysis of the 50 most influential publications on distal biceps repair.
    Binyamin R Abramowitz, Steven M Koehler, William R Aibinder.
      PURPOSE: The purpose of this bibliometric study was to identify and analyze the most cited publications on acute distal biceps repair.METHODS: Using the Clarivate Analytics Web of Science database, we searched for the top 50 most cited publications on acute distal biceps repair and analyzed them based on various metrics.
    RESULTS: The top 50 publications were cited a total of 3171 times and approximately 151 times per year. However, although the literature on the topic is quite extensive, most publications only contain low-level evidence. In fact, 74% of the 50 most cited publications on the topic contain either level IV or V evidence.
    CONCLUSION: This study, through bibliometric analysis, demonstrates that the most often cited studies about acute distal biceps tendon repair are low level of evidence designs. This common injury and study design are ripe for larger randomized or prospective cohort studies.

    The 100 most cited papers on retinal detachment: a bibliographic perspective.
    Andrzej Grzybowski, Chen Shtayer, Stephen G Schwartz, Elad Moisseiev.
      The 100 most cited papers on retinal detachment (RD) were analysed using a bibliographic study. The bibliographic databases of the ISI Web of Knowledge were searched, limited to research articles published between 1965 and 2020 in peer-reviewed journals. The papers were ranked in order of number of citations since publication. Ninety of the 100 most cited papers on RD were published in 12 ophthalmology journals, with 74 of them published in American Journal of Ophthalmology (n=31), Ophthalmology (n=23), Archives of Ophthalmology (n=10) and Investigative Ophthalmology and Visual Science (n=10); the remaining 10 papers were published in 8 journals from other fields of medical research. All papers in the top 100 were published in English. The 100 most cited papers on RD originated from 12 different countries, with the majority (72 papers) originating from the USA. The 100 identified papers represent a mix of clinical trials and animal/laboratory studies. This bibliographic study provides a unique perspective and insight into some of the most influential contributions in RD understanding and management over the last 55 years.

    Publication Trends in Neglected Tropical Diseases of Latin America and the Caribbean: A Bibliometric Analysis.
    Gustavo Fontecha, Ana Sánchez, Bryan Ortiz.
      (1) Background: Neglected tropical diseases (NTDs) have been overlooked on the global health agenda and in the priorities of national systems in low- and middle-income countries (LMICs). In 2012, the Sustainable Development Goals (SDGs) were created to ensure healthy lives and promoting well-being for all. This roadmap set out to accelerate work to overcome the global impact of NTDs. Almost a decade has passed since NTDs were re-launched as a global priority. Investment in research and development, as well as the production of scientific literature on NTDs, is expected to have increased significantly. (2) Methods: A bibliometric analysis of the scientific production of Latin America and the Caribbean (LAC) was carried out in relation to 19 endemic NTDs. These data were compared with the scientific production in malaria, tuberculosis, and HIV/AIDS. The database available from Thomson Reuters Web of Science (WoS) was used. In addition, the average annual growth percentage was calculated for each disease. (3) Results: In the last decade, the NTDs with the highest number of publications in the world were dengue and leishmaniasis. The United States was the most prolific country in the world in 15 out of 19 NTDs analyzed. In the LAC region, Brazil was the largest contributor for 16 of the 19 NTDs analyzed. Arboviral diseases showed the highest average annual growth. The number of publications for malaria, tuberculosis and HIV/AIDS was considerably higher than for NTDs. The contribution of most LAC countries, especially those considered to be LMICs, is inadequate and does not reflect the relevance of NTDs for the public health of the population. (4) Conclusions: This is the first bibliometric analysis to assess the trend of scientific documents on endemic NTDs in LAC. Our results could be used by decision makers both to strengthen investment policies in research and development in NTDs.

    Laser Powder Bed Fusion of Polymers: Quantitative Research Direction Indices.
    Ihsan Murat Kusoglu, Carlos Doñate-Buendía, Stephan Barcikowski, Bilal Gökce.
      Research on Laser Powder Bed Fusion (L-PBF) of polymer powder feedstocks has raised over the last decade due to the increased utilization of the fabricated parts in aerospace, automotive, electronics, and healthcare applications. A total of 600 Science Citation Indexed articles were published on the topic of L-PBF of polymer powder feedstocks in the last decade, being cited more than 10,000 times leading to an h-index of 46. This study statistically evaluates the 100 most cited articles to extract reported material, process, and as-built part properties to analyze the research trends. PA12, PEEK, and TPU are the most employed polymer powder feedstocks, while size, flowability, and thermal behavior are the standardly reported material properties. Likewise, process properties such as laser power, scanning speed, hatch spacing, powder layer thickness, volumetric energy density, and areal energy density are extracted and evaluated. In addition, material and process properties of the as-built parts such as tensile test, flexural test, and volumetric porosity contents are analyzed. The incorporation of additives is found to be an effective route to enhance mechanical and functional properties. Carbon-based additives are typically employed in applications where mechanical properties are essential. Carbon fibers, Ca-phosphates, and SiO2 are the most reported additives in the evaluated SCI-expanded articles for L-PBF of polymer powder feedstocks. A comprehensive data matrix is extracted from the evaluated SCI-index publications, and a principal component analysis (PCA) is performed to explore correlations between reported material, process, and as-built parts.

    Urban Food Systems: A Bibliometric Review from 1991 to 2020.
    Qiumeng Zhong, Lan Wang, Shenghui Cui.
      The increase of urbanization is affecting the urban food system (UFS) in many areas, primarily production, processing, and consumption. The upgrading of the urban food consumption structure not only puts forward higher food production requirements, but also poses a challenge to resource consumption and technological innovation. Considerable case or review studies have been conducted on UFS, but there is no bibliometric review attempting to provide an objective and comprehensive analysis of the existing articles. In this study, we selected 5360 research publications from the core Web of Science collection from 1991 to 2020, analyzing contributions of countries, institutions, and journals. In addition, based on keyword co-occurrence and clustering analyses, we evaluated the research hotspots of UFS. The results show that global research interest in UFS has increased significantly during these three decades. The USA, China, and the UK are the countries with the highest output and closest collaborations. UFS research involves multiple subject categories, with environmental disciplines becoming mainstream. Food security, food consumption, and food waste are the three main research areas. We suggest that food sustainability and resilience, food innovation, and comparative studies between cities should be given more attention in the future.

    Contemporary Trends and End-Results of National Institute of Health Grant Funding to Departments of Urology in the United States: A 10-year Analysis.
    Nizar Hakam, Michael Sadighian, Behnam Nabavizadeh, Natalie Rios, Gregory Amend, Andrew J Cohen, Benjamin N Breyer.
      PURPOSE: To explore the patterns and distribution of National Institutes of Health (NIH) grant funding for Urologic research in the United States.MATERIALS AND METHODS: The NIH RePORTER database was queried for all grants awarded to Urology Departments between 2010 and 2019. Information regarding the value of the grant, funded institution, successful publication of the research, and the category of Urologic subspecialty were collected. Data on principal investigators was extracted from publicly available information.
    RESULTS: There were 509 grants awarded to Urology between 2010 and 2019 for a total value of $640,873,867, and a median per-project value of $675,484 (IQR 344,170-1,369,385). Over the study period, total funding decreased by 15.6% and was lower compared to other surgical subspecialties. Most grants were awarded by the National Cancer Institute and National Institute of Diabetes and Digestive and Kidney Diseases (85%), to Western or North Central institutions (52.5%), and had principal investigators specialized in urologic oncology (56.4%), followed by general urologists (21.5%). Female principal investigators led 21.6% of Urology grants and were more likely PhD basic scientists than males (64.4% vs 38.2%, p=0.001). In total, 10,404 publications linked to the 509 grants were produced, of which 28.5% were published in journals with an impact factor ≥10.
    CONCLUSIONS: Urology is underrepresented in NIH grant funding compared to other surgical fields. During the past decade there was a further decrease in the total budget of NIH grants to Urology.

    A Bibliometric Analysis on Dengue Outbreaks in Tropical and Sub-Tropical Climates Worldwide Since 1950.
    Shin-Yueh Liu, Tsair-Wei Chien, Ting-Ya Yang, Yu-Tsen Yeh, Willy Chou, Julie Chi Chow.
      Severe dengue outbreaks (DOs) affect the majority of Asian and Latin American countries. Whether all DOs always occurred in sub-tropical and tropical areas (STTA) has not been verified. We downloaded abstracts by searching keywords "dengue (MeSH Major Topic)" from Pubmed Central since 1950, including three collections: country names in abstracts (CNA), no abstracts (WA), and no country names in abstracts (Non-CNA). Visualizations were created to present the DOs across countries/areas in STTA. The percentages of mentioned country names and authors' countries in STTA were computed on the CNA and Non-CNA bases. The social network analysis was applied to highlight the most cited articles and countries. We found that (1) three collections are 3427 (25.48%), 3137 (23.33%), and 6884 (51.19%) in CNA, WA, and Non-CNA, respectively; (2) the percentages of 94.3% and 79.9% were found in the CNA and Non-CNA groups; (3) the most mentioned country in abstracts were India, Thailand, and Brazil; (4) most authors in the Non-CNA collections were from the United States, Brazil, and China; (5) the most cited article (PMID = 23563266) authored by Bhatt et al. had 2604 citations since 2013. Our findings provide in-depth insights into the DO knowledge. The research approaches are recommended for authors in research on other infectious diseases in the future, not just limited to the DO topic.

    The gender gap in European neurosurgical conference presentations.
    Julie Woodfield, Phillip Correia Copley, Mark Hughes, Ellie Edlmann.
      OBJECTIVE: Within neurosurgery, there are fewer women than men at all levels. The authors aimed to assess whether opportunities and representation within neurosurgery are proportional to the existing gender gap.METHODS: The authors analyzed the program of the 2019 joint European Association of Neurosurgical Societies (EANS)/Society of British Neurological Surgeons (SBNS) conference to assess the proportions of presentations given through abstract submission and invitation by men and women. They compared proportions to the previous joint conference in 2007 and to the gender proportions of board-certified European neurosurgeons.
    RESULTS: Women delivered 75/577 (13%) presentations at the 2019 EANS/SBNS conference: 54/283 (19%) abstract submissions and 21/294 (7%) invited presentations. Fifteen of 152 (10%) session chairs were women. This increased significantly from 4/121 (3%) presentations delivered by women in 2007. When only presentations given by neurosurgeons (residents or consultants) were analyzed, the proportion of female speakers increased from 1/111 (1%) in 2007 to 60/545 (11%) in 2019. Pediatrics was the subspecialty with the highest proportion of invited female speakers. Across subspecialties, there were no differences in gender proportions for presentations from abstract submissions. Across the top 5 participating European countries, the proportion of female invited speakers (8%) and chairs (8%) was half the proportion of female board-certified neurosurgeons (16%).
    CONCLUSIONS: The proportion of women delivering invited presentations and chairing sessions at a European neurosurgical conference is lower than expected from the available pool of board-certified neurosurgeons. The proportion of women participating is higher through application (abstract submission) than through invitation. The higher proportion of presentations from abstract submission may reflect submission from a pool of trainees with a higher proportion of women. The authors suggest implementation of strategies that increase invited speakers from minority groups and have been shown to be effective in other disciplines, such as improving minority group representation in organizing committees.

    [Knowledge map analysis of research progress of Strychni Semen based on CiteSpace].
    Shi-Qi Kang, Jing-Hang Yang, Xiao-Hui Su, Na Lin, Xiang-Ying Kong.
      To analyze the study advance of Strychni Semen, a kind of traditional Chinese medicine, this study systematically retrieved the related Chinese literatures about Strychni Semen from CNKI database platforms and the core database of Web of Science, and used bibliometrics and CiteSpace 5.6.R5 software to visually display the authors, research institutions, keywords and other contents. A total of 1 895 Chinese literatures and 1 599 English literatures were included in the study. The analysis of Chinese and English literature authors showed that CAI Bao-chang and CHEN Jun had the most publications on Strychni Semen, and CAI Bao-chang's team was the core research team. According to the analysis of publishing institutions, Nanjing University of Traditional Chinese Medicine and Chinese Academy of Science were the research institutions with the largest number of Chinese and English literatures, respectively. But there was less cooperation between Chinese and English study institutions. The analysis of keywords in Chinese and English literatures showed that the research contents of Strychni Semen mainly focused on component analysis, research methods, receptor targets, clinical application, synergistic and attenuation measures. Break analysis showed that the apoptosis induced by Strychni Semen was a hot research topic, and research on components, toxicity and pharmacokinetics will be the research hotspot in future. The research on Strychni Semen is still in the developing period. This study has provided reference for the rapid grasp of the research contents and the judgment of research hotspots.

    Mapping the terrain of Journal of Counseling Psychology: A citation network analysis.
    Mike C Parent, Bonnie Moradi, Alexandra S Weis, Staci Ouch.
      In this study, we conducted a citation network analysis of the Journal of Counseling Psychology (JCP) to elucidate the scope, evolution, and interconnections of JCP publications as reflected in how authors use (i.e., cite) these publications. We used CitNetExplorer to analyze a network of 4,718 JCP publications and 16,959 citation links. The analysis yielded 19 clusters in JCP's citation network. The most dominant facet of the citation network focused on counseling, counseling process, and counseling outcome. The clusters in this facet shifted from an early focus on perceptions of counselors to continuing examinations of what happens in counseling. Another dominant facet comprised clusters on vocational psychology, shifting from an earlier focus on vocational choice and interest, to career counseling and decision making, to vocational and academic development processes and predictors. These major facets converged toward a continuing cluster focused on methodology and analysis along with race, gender, sexuality, and other diversity scholarship. This suggests that diversity-focused publications in JCP often employ and cite methodological and analytic advances. The results also reveal discontinued areas of scholarship in JCP that are ripe for revisiting and rebuilding in new directions (e.g., anger and social justice activism; clinical judgment and artificial intelligence). The results suggest that a promising next step in the evolution of JCP would be for authors to engage with and cite diversity scholarship as central to "general" domains of JCP scholarship.

    Requiem for impact factors and high publication charges.
    Chris R Triggle, Ross MacDonald, David J Triggle, Donald Grierson.
      Journal impact factors, publication charges and assessment of quality and accuracy of scientific research are critical for researchers, managers, funders, policy makers, and society. Editors and publishers compete for impact factor rankings, to demonstrate how important their journals are, and researchers strive to publish in perceived top journals, despite high publication and access charges. This raises questions of how top journals are identified, whether assessments of impacts are accurate and whether high publication charges borne by the research community are justified, bearing in mind that they also collectively provide free peer-review to the publishers. Although traditional journals accelerated peer review and publication during the COVID-19 pandemic, preprint servers made a greater impact with over 30,000 open access articles becoming available and accelerating a trend already seen in other fields of research. We review and comment on the advantages and disadvantages of a range of assessment methods and the way in which they are used by researchers, managers, employers and publishers. We argue that new approaches to assessment are required to provide a realistic and comprehensive measure of the value of research and journals and we support open access publishing at a modest, affordable price to benefit research producers and consumers.

    A Quantitative and Qualitative Review on the Main Research Streams Regarding Blockchain Technology in Healthcare.
    Yong Sauk Hau, Min Cheol Chang.
      (1) Background: Blockchain technology has been gaining high popularity in the healthcare domain. This has brought about a spate of recent studies regarding blockchain technology in healthcare, creating high demand for quantitative or qualitative reviews on the main research streams thereof. In order to contribute to satisfying the high demand, this research presents a quantitative and qualitative review on studies regarding blockchain technology in healthcare. (2) Methods: A quantitative review was performed by searching the Web of Science database for articles published until 10 March in 2020, and a qualitative review was conducted by using the content analysis based on the integrative view of Leavitt's diamond model. (3) Results: The quantitative review identified five research streams. The number of articles about blockchain technology in healthcare has dramatically increased since 2016, with a compound annual growth rate of 254.4%. English is the most dominant language used in the articles, and the USA and China are the top two countries of origin of the articles, representing overwhelming portions. The IEEE Access, Journal of Medical Systems, Journal of Medical Internet Research, Applied Sciences Basel, and Sensors are the top five journals in terms of publication. The articles showed an L-shaped distribution in terms of their annual average numbers of citations. The qualitative review revealed two research streams. Most of the top 10 articles ranked by their annual average numbers of citations concentrated on developing or proposing new technological solutions using blockchain technology to effectively revolutionize the current methods of managing data in the healthcare domain. The majority of the top 10 articles pursued the convergence of blockchain technology with cloud technology or IoT. (4) Conclusions: This article illuminates the main research streams about blockchain technology in healthcare through a quantitative and qualitative review, providing implications for future research on blockchain technology.

    X Y Ji, Z Zeng.
      Objective: To summarize the research progress of medical emotional labor in China, and provide data reference for medical workers in the field of emotional labor. Methods: In March 2020, we searched the research content of emotional labor of medical workers through CNKI system, and analyzed it by using CiteSpace software. We visualized the topic of emotional labor of medical workers by using the knowledge map formed by keyword co-occurrence and keyword clustering, as well as the emergent words and time zone map. The analysis contents include the basic information characteristics of the selected literature, research hotspots and topics, research trends and frontiers. Results: The first related literature was published in 2008, and 126 related literatures were retrieved. Research hotspots include 'emotional labor', 'nurse', 'work burnout', 'medical staff' and 'work satisfaction', etc. Topics can be divided into three categories: research objects, variables affecting factors and medical workplace. There are 24 emergent words. In 2008, 2011, 2013, and 2015, important turning points for research changes exist. Conclusion: In the future, researchers in China can try to broaden the scope of medical subjects and influencing factors, etc., and be closely linked to the results of existing studies.

      Soil erosion can present a major threat to agriculture due to loss of soil, nutrients, and organic carbon. Therefore, soil erosion modelling is one of the steps used to plan suitable soil protection measures and detect erosion hotspots. A bibliometric analysis of this topic can reveal research patterns and soil erosion modelling characteristics that can help identify steps needed to enhance the research conducted in this field. Therefore, a detailed bibliometric analysis, including investigation of collaboration networks and citation patterns, should be conducted. The updated version of the Global Applications of Soil Erosion Modelling Tracker (GASEMT) database contains information about citation characteristics and publication type. Here, we investigated the impact of the number of authors, the publication type and the selected journal on the number of citations. Generalized boosted regression tree (BRT) modelling was used to evaluate the most relevant variables related to soil erosion modelling. Additionally, bibliometric networks were analysed and visualized. This study revealed that the selection of the soil erosion model has the largest impact on the number of publication citations, followed by the modelling scale and the publication's CiteScore. Some of the other GASEMT database attributes such as model calibration and validation have negligible influence on the number of citations according to the BRT model. Although it is true that studies that conduct calibration, on average, received around 30% more citations, than studies where calibration was not performed. Moreover, the bibliographic coupling and citation networks show a clear continental pattern, although the co-authorship network does not show the same characteristics. Therefore, soil erosion modellers should conduct even more comprehensive review of past studies and focus not just on the research conducted in the same country or continent. Moreover, when evaluating soil erosion models, an additional focus should be given to field measurements, model calibration, performance assessment and uncertainty of modelling results. The results of this study indicate that these GASEMT database attributes had smaller impact on the number of citations, according to the BRT model, than anticipated, which could suggest that these attributes should be given additional attention by the soil erosion modelling community. This study provides a kind of bibliographic benchmark for soil erosion modelling research papers as modellers can estimate the influence of their paper.

    Neuroimaging Research on Dementia in Brazil in the Last Decade: Scientometric Analysis, Challenges, and Peculiarities.
    Liara Rizzi, Ítalo Karmann Aventurato, Marcio L F Balthazar.
      The last years have evinced a remarkable growth in neuroimaging studies around the world. All these studies have contributed to a better understanding of the cerebral outcomes of dementia, even in the earliest phases. In low- and middle-income countries, studies involving structural and functional neuroimaging are challenging due to low investments and heterogeneous populations. Outstanding the importance of diagnosing mild cognitive impairment and dementia, the purpose of this paper is to offer an overview of neuroimaging dementia research in Brazil. The review includes a brief scientometric analysis of quantitative information about the development of this field over the past 10 years. Besides, discusses some peculiarities and challenges that have limited neuroimaging dementia research in this big and heterogeneous country of Latin America. We systematically reviewed existing neuroimaging literature with Brazilian authors that presented outcomes related to a dementia syndrome, published from 2010 to 2020. Briefly, the main neuroimaging methods used were morphometrics, followed by fMRI, and DTI. The major diseases analyzed were Alzheimer's disease, mild cognitive impairment, and vascular dementia, respectively. Moreover, research activity in Brazil has been restricted almost entirely to a few centers in the Southeast region, and funding could be the main driver for publications. There was relative stability concerning the number of publications per year, the citation impact has historically been below the world average, and the author's gender inequalities are not relevant in this specific field. Neuroimaging research in Brazil is far from being developed and widespread across the country. Fortunately, increasingly collaborations with foreign partnerships contribute to the impact of Brazil's domestic research. Although the challenges, neuroimaging researches performed in the native population regarding regional peculiarities and adversities are of pivotal importance.

    Reaching over the gap: A review of trends in and status of red panda research over 193 years (1827-2020).
    Sikha Karki, Tek Maraseni, Brendan Mackey, Damber Bista, Sonam Tashi Lama, Ambika P Gautam, Ang Phuri Sherpa, Upama Koju, Anita Shrestha, Tim Cadman.
      The red panda is a unique species taxonomically known for its peculiar biological and ecological characteristics, and extreme attractiveness. Despite being highly significant from conservation, scientific and economic perspectives, this species has experienced a declining population in the wild. Thus, to direct further research priorities and conservation actions and assess gaps in the current research trend of this species, a systematic literature review was conducted covering 175 journal articles published in English over 193 years (1827-2020). This review revealed that (1) the biological aspect was highly studied compared to other thematic areas of red panda (2) captive-based studies are relatively higher than the studies based in wild populations (3) China is leading the red panda studies amongst all red panda range (4) The universities were found contributing more to red panda studies than other institutions. Surprisingly, we found that the researchers from the non-range country were leading red panda study than those from range countries. Our review highlighted the need of prioritising studies in underrepresented locations and understudied thematic areas focusing on the assessment of climate change impact, bamboo distribution status, ecosystem services of red panda habitat, behavior and movement ecology, population estimation, and metapopulation dynamics. We urge landscape-level studies and long-term population monitoring. Besides, we also suggest the documentation and evaluation of the effectiveness of ongoing red panda-focused conservation programs. We also stress the need for strengthening the capacity of institutions and people from range countries.

    Wormicloud: a new text summarization tool based on word clouds to explore the C. elegans literature.
    Valerio Arnaboldi, Jaehyoung Cho, Paul W Sternberg.
      Finding relevant information from newly published scientific papers is becoming increasingly difficult due to the pace at which articles are published every year as well as the increasing amount of information per paper. Biocuration and model organism databases provide a map for researchers to navigate through the complex structure of the biomedical literature by distilling knowledge into curated and standardized information. In addition, scientific search engines such as PubMed and text-mining tools such as Textpresso allow researchers to easily search for specific biological aspects from newly published papers, facilitating knowledge transfer. However, digesting the information returned by these systems-often a large number of documents-still requires considerable effort. In this paper, we present Wormicloud, a new tool that summarizes scientific articles in a graphical way through word clouds. This tool is aimed at facilitating the discovery of new experimental results not yet curated by model organism databases and is designed for both researchers and biocurators. Wormicloud is customized for the Caenorhabditis  elegans literature and provides several advantages over existing solutions, including being able to perform full-text searches through Textpresso, which provides more accurate results than other existing literature search engines. Wormicloud is integrated through direct links from gene interaction pages in WormBase. Additionally, it allows analysis on the gene sets obtained from literature searches with other WormBase tools such as SimpleMine and Gene Set Enrichment.

    Career Research Productivity Correlates With Medical School Ranking Among Cardiothoracic Surgeons.
    Simar S Bajaj, Hanjay Wang, Kiah M Williams, Joshua M Pickering, Joseph C Heiler, Keerthi Manjunatha, Mark Sanchez, Christian T O'Donnell, Jack H Boyd.
      BACKGROUND: The foundation for a successful academic surgical career begins in medical school. We examined whether attending a top-ranked medical school is correlated with enhanced research productivity and faster career advancement among academic cardiothoracic (CT) surgeons.MATERIALS AND METHODS: Research profiles and professional histories were obtained from publicly available sources for all CT surgery faculty at accredited US CT surgery teaching hospitals in 2018 (n = 992). We focused on surgeons who completed medical school in the United States during or after 1990, the first-year US News & World Report released its annual medical school research rankings (n = 451). Subanalyses focused on surgeons who completed a research fellowship (n = 299) and those who did not (n = 152).
    RESULTS: A total of 124 surgeons (27.5%) attended a US News & World Report top 10 medical school, whereas 327 (72.5%) did not. Surgeons who studied at a top 10 medical school published more articles per year as an attending surgeon (3.2 versus 1.9; P < 0.0001), leading to more total publications (51.5 versus 27.0; P < 0.0001) and a higher H-index (16.0 versus 11.0; P < 0.0001) over a similar career duration (11.0 versus 10.0 y; P = 0.1294). These differences in career-long research productivity were statistically significant regardless of whether the surgeons completed a research fellowship or not. The surgeons in both groups, however, required a similar number of years to reach associate professor rank (P = 0.6993) and full professor rank (P = 0.7811) after starting their first attending job.
    CONCLUSIONS: Attending a top-ranked medical school is associated with enhanced future research productivity but not with faster career advancement in academic CT surgery.

    The Effect of a Points System on Incentivizing Academic Behaviors of Attending Ophthalmologists.
    Darren A Chen, Emily Cohen, Gary J Lelli.
      (1) Background: Little is known regarding the best ways to promote academic throughput within the ranks of attending ophthalmology physicians. The purpose of this project is to evaluate the effect of a monetized points system on incentivizing research output and other academic activity in academic ophthalmology attendings. (2) Methods: This is a retrospective study of 15 academic ophthalmology attendings at a single academic teaching hospital from 1 July 2015 to 30 June 2020. A points system was implemented in the 2017 academic year (1 July 2016-30 June 2017), in which ophthalmology attendings accrued points for eight categories of academic achievement. We compared the overall number of publications, number of first/senior author publications, and corresponding impact factors of journals via the PubMed database in the two years of data before and after the points system was implemented. We analyzed points awarded for eight categories of academic achievement in the first, second, and third year of the program. (3) Results: There was no significant change in research productivity for attending ophthalmologists after institution of the points system. From 2017 to 2019, Mann-Whitney analysis revealed a significant increase in points awarded for mentorship per physician (p = 0.013). (4) Conclusions: Our data suggest that within the framework of the points system, attendings-rather than prioritizing publications-gravitated towards mentorship activities to accrue points.

    ReCiter: An open source, identity-driven, authorship prediction algorithm optimized for academic institutions.
    Paul J Albert, Sarbajit Dutta, Jie Lin, Zimeng Zhu, Michael Bales, Stephen B Johnson, Mohammad Mansour, Drew Wright, Terrie R Wheeler, Curtis L Cole.
      Academic institutions need to maintain publication lists for thousands of faculty and other scholars. Automated tools are essential to minimize the need for direct feedback from the scholars themselves who are practically unable to commit necessary effort to keep the data accurate. In relying exclusively on clustering techniques, author disambiguation applications fail to satisfy key use cases of academic institutions. Algorithms can perfectly group together a set of publications authored by a common individual, but, for them to be useful to an academic institution, they need to programmatically and recurrently map articles to thousands of scholars of interest en masse. Consistent with a savvy librarian's approach for generating a scholar's list of publications, identity-driven authorship prediction is the process of using information about a scholar to quantify the likelihood that person wrote certain articles. ReCiter is an application that attempts to do exactly that. ReCiter uses institutionally-maintained identity data such as name of department and year of terminal degree to predict which articles a given scholar has authored. To compute the overall score for a given candidate article from PubMed (and, optionally, Scopus), ReCiter uses: up to 12 types of commonly available, identity data; whether other members of a cluster have been accepted or rejected by a user; and the average score of a cluster. In addition, ReCiter provides scoring and qualitative evidence supporting why particular articles are suggested. This context and confidence scoring allows curators to more accurately provide feedback on behalf of scholars. To help users to more efficiently curate publication lists, we used a support vector machine analysis to optimize the scoring of the ReCiter algorithm. In our analysis of a diverse test group of 500 scholars at an academic private medical center, ReCiter correctly predicted 98% of their publications in PubMed.

    Causes and Effects of Introducing Surgery Safety Checklist: A Review.
    Jacek Lorkowski, Izabella Maciejowska-Wilcock, Mieczysław Pokorski.
      The medical treatment process, particularly surgery, is inescapably bound to potential complications or undesirable adverse events. This narrative review aims to present the causes and effects of the introduction of the WHO Surgery Safety Checklist (SSC), the use of which is expected to reduce the number of perioperative errors, complications, and mortality. To achieve this objective, we performed a bibliometric analysis of medical citations indexed in the PubMed database using the SSC subject heading. Findings revealed a total of 1441 articles meeting inclusion status, with 1171 published during the last decade. After the screening of titles and abstracts, the members of the research team selected 75 articles, deemed most relevant for inclusion in the review, which were then thoroughly analyzed. All in all, the findings were that the use of SSC appreciably reduced the number of simple logistic errors in the perioperative period decreasing the frequency of resulting complications and mortality.

    Data Mining in Healthcare: Applying Strategic Intelligence Techniques to Depict 25 Years of Research Development.
    Maikel Luis Kolling, Leonardo B Furstenau, Michele Kremer Sott, Bruna Rabaioli, Pedro Henrique Ulmi, Nicola Luigi Bragazzi, Leonel Pablo Carvalho Tedesco.
      In order to identify the strategic topics and the thematic evolution structure of data mining applied to healthcare, in this paper, a bibliometric performance and network analysis (BPNA) was conducted. For this purpose, 6138 articles were sourced from the Web of Science covering the period from 1995 to July 2020 and the SciMAT software was used. Our results present a strategic diagram composed of 19 themes, of which the 8 motor themes ('NEURAL-NETWORKS', 'CANCER', 'ELETRONIC-HEALTH-RECORDS', 'DIABETES-MELLITUS', 'ALZHEIMER'S-DISEASE', 'BREAST-CANCER', 'DEPRESSION', and 'RANDOM-FOREST') are depicted in a thematic network. An in-depth analysis was carried out in order to find hidden patterns and to provide a general perspective of the field. The thematic network structure is arranged thusly that its subjects are organized into two different areas, (i) practices and techniques related to data mining in healthcare, and (ii) health concepts and disease supported by data mining, embodying, respectively, the hotspots related to the data mining and medical scopes, hence demonstrating the field's evolution over time. Such results make it possible to form the basis for future research and facilitate decision-making by researchers and practitioners, institutions, and governments interested in data mining in healthcare.

    International trends in grant and fellowship funding awarded to women in neurosurgery.
    Kimberly Wang, Archis R Bhandarkar, Megan M J Bauman, Cecile Riviere-Cazaux, Juliana Rotter, Kristen M Scheitler, Jaclyn J Renfrow, Michelle J Clarke.
      OBJECTIVE: Metric tracking of grant funding over time for academic neurosurgeons sorted by gender informs the current climate of career development internationally for women in neurosurgery.METHODS: Multivariate linear trend analysis of grant funding awarded to neurosurgeons in the NIH and World Research Portfolio Online Reporting Tools Expenditures and Results (RePORTER) was performed. Traveling fellowships for international neurosurgery residents sponsored by the AANS and Congress of Neurological Surgeons (CNS) were also analyzed.
    RESULTS: Within the US, funding awarded to female neurosurgeons has remained static from 2009 to 2019 after adjusting for inflation and overall trends in NIH funding (β = -$0.3 million per year, p = 0.16). Internationally, female neurosurgeons represented 21.7% (n = 5) of project leads for World RePORTER grants. Traveling fellowships are also an important building block for young international female neurosurgeons, of which 7.4% (n = 2) of AANS international traveling fellowships and 19.4% (n = 7) of AANS/CNS pediatrics international traveling fellowships are women.
    CONCLUSIONS: Over the past decade, funding has increased in neurosurgery without a concordant increase in funding awarded to women. Recognition of this trend is essential to focus efforts on research and career development opportunities for women in neurosurgery. Worldwide, female neurosurgeons head one-fifth of the funded project leads and constitute a minority of international traveling fellowships awarded by organized neurosurgery.

    The impact of authors' medical specialty on publication patterns and published results of adjuvant radiotherapy for WHO grade 2 meningiomas-a systematic review.
    Per Sveino Strand, Ole Solheim.
      BACKGROUND: The role of adjuvant radiotherapy after gross total resection (GTR) of WHO grade 2 meningioma remains unclear, and conflicting results have been published. We hypothesized that authors' medical specialties could be associated with reported findings on the role of adjuvant radiotherapy after GTR of WHO grade 2 meningiomas.METHOD: A systematic review was conducted in Embase and Medline databases, in addition to screening of all relevant bibliographies. Articles including patients aged 18 years or older, with histologically confirmed WHO grade 2 meningioma, were included. We extracted data on medical subspecialties using the author list. We registered study design, median follow-up, number of included patients, WHO classification in use, and years of study inclusion.
    RESULTS: Thirty-seven relevant studies were identified, where 34 (92%) were retrospective cohort studies, two studies (5%) were systematic reviews, and one study (3%) was a meta-analysis. If the last author was a radiation-oncologist, the study was more likely to favor adjuvant radiotherapy, and if a neurosurgeon was last author, the study was more likely to not advocate adjuvant radiotherapy (p=0.009). There was no significant association between study result and whether the study was published in a neurosurgical or oncological journal (p=0.802). There was no significant difference in follow-up time, years of inclusion, or number of included patients between studies favoring or not favoring adjuvant radiotherapy.
    CONCLUSIONS: In this systematic review of the literature, we found that if a radiation-oncologist was the last author of the study, the study was more likely to favor adjuvant radiotherapy after gross total resection of WHO grade 2 meningioma. Clinicians and researchers should be aware of a possible genealogy bias in the neuro-oncological literature.

    How Does Representation of Women on Editorial Boards Compare Among Orthopaedic, General Surgery, and Internal Medicine Journals?
    James S Lin, Kristy L Weber, Julie Balch Samora.
      BACKGROUND: Women have historically been underrepresented as editors of peer-reviewed medical journals. Studies have demonstrated that there are differences in editorial board reviewer behavior based on gender, suggesting that greater representation by women on editorial boards may improve the quality and diversity of the review process. Therefore, the current representation of women on the editorial boards of orthopaedic journals, particularly compared with peer-reviewed surgical and medical journals, is of interest.QUESTIONS/PURPOSES: (1) What is the representation of women as members of editorial boards of prominent orthopaedic surgery journals? (2) How does it compare with representation on the editorial boards of journals in general surgery and internal medicine?
    METHODS: The top 15 journals with a strong clinical emphasis based on Impact Factor (Clarivate Analytics) calculated by the 2018 Journal Citation Reports were identified for orthopaedic surgery, general surgery (and all general surgical subspecialties), and internal medicine (with representative internal medicine subspecialties). Clinical publications with their primary editorial office located in the United States led predominantly by physicians or basic scientists were eligible for inclusion. The members of an editorial board were identified from the journals' websites. The gender of editors with gender-neutral names (and editors whose gender we considered uncertain) was identified by an internet search for gender-specific pronouns and/or pictures from an institutional profile. Fisher exact tests and t-tests were used to analyze categorical and continuous variables, respectively. Significance was set at p < 0.05.
    RESULTS: Of the editors analyzed, women made up 9% (121 of 1383) of editorial boards in the orthopaedic journals with the highest Impact Factors, compared with 21% (342 of 1665) of general surgery journals (p < 0.001) and 35% (204 of 587) of internal medicine journals (p < 0.001). The overall mean composition of editorial boards of orthopaedic journals was 10% ± 8% women, compared with that of general surgery, which was 19% ± 6% women (p < 0.001), and that of internal medicine, which was 40% ± 19% women (p < 0.001).
    CONCLUSION: Women make up a smaller proportion of editorial boards at orthopaedic surgery journals than they do at general surgery and internal medicine journals. However, their representation appears to be comparable to the proportion of women in orthopaedics overall (approximately 6%) and the proportion of women in academic orthopaedics (approximately 19%). Ways to improve the proportion of women on editorial boards might include structured mentorship programs at institutions and personal responsibility for championing mentorship and diversity on an individual level.
    CLINICAL RELEVANCE: Increasing representation of women on editorial boards may improve the diversity of perspectives and quality of future published research, generate visible role models for young women considering orthopaedics as a career, and improve patient care through enriching the diversity of our specialty.

    A Scientometric Approach to Review the Role of the Medial Preoptic Area (MPOA) in Parental Behavior.
    Alessandro Carollo, Jan Paolo Macapinlac Balagtas, Michelle Jin-Yee Neoh, Gianluca Esposito.
      Research investigating the neural substrates underpinning parental behaviour has recently gained momentum. Particularly, the hypothalamic medial preoptic area (MPOA) has been identified as a crucial region for parenting. The current study conducted a scientometric analysis of publications from 1 January 1972 to 19 January 2021 using CiteSpace software to determine trends in the scientific literature exploring the relationship between MPOA and parental behaviour. In total, 677 scientific papers were analysed, producing a network of 1509 nodes and 5498 links. Four major clusters were identified: "C-Fos Expression", "Lactating Rat", "Medial Preoptic Area Interaction" and "Parental Behavior". Their content suggests an initial trend in which the properties of the MPOA in response to parental behavior were studied, followed by a growing attention towards the presence of a brain network, including the reward circuits, regulating such behavior. Furthermore, while attention was initially directed uniquely to maternal behavior, it has recently been extended to the understanding of paternal behaviors as well. Finally, although the majority of the studies were conducted on rodents, recent publications broaden the implications of previous documents to human parental behavior, giving insight into the mechanisms underlying postpartum depression. Potential directions in future works were also discussed.

    Analysis of Gender Disparity in US and Canadian Radiology Residency Programs.
    Sami Adham, Frank J Rybicki, Mary C Mahoney, Charlotte J Yong-Hing, Faisal Khosa.
      BACKGROUND: Equity, diversity, and inclusion in academic radiology are a work in progress and although the gender gap has decreased, there remains a paucity of studies examining female representation among radiology trainees over the past decade.OBJECTIVE: The aim of our undertaking was to evaluate gender parity in United States (US) and Canadian radiology residency programs and to suggest future directions to improve female representation MATERIALS AND METHODS: Retrospective analysis of publicly available data on radiology residents from the US and Canada was performed from 2007to 2019. Data on diagnostic radiology residents was collected from the Accreditation Council for Graduate Medical Education for the US and the Canadian Post M.D. Education Registry for Canada. Statistical tests including regression and ANOVA were used to study the gender proportions from 2007to 2019.
    RESULTS: There has been little progress in bridging the gender gap in the last 12 years. The proportion of female residents pursuing radiology has remained at an average of 26.74% (n = 1,238of 4,629) in US programs and 31.78% (n = 28 of88) in Canadian programs. The average change in the percentage of female residents was 0.0% per year (P = 0.0) for US programs and -2.9% per year (P = 0.3) for Canadian programs.
    DISCUSSION: Despite a higher proportion of females in North American medical schools, gender disparity persists among radiology residents. More research is needed to identify barriers limiting female representation and improve gender parity across North American radiology programs.

    Characteristics and Distribution of Surgical Diseases in North Korean Research Papers Published between 2006 and 2017.
    Yo Han Lee, Namkee Oh, Hyerim Kim, Shin Ha.
      BACKGROUND: Little is known about the surgical discipline in North Korea from the perspective of the outside world. This study aimed to examine the disease entities covered by articles published in the major medical journal in North Korea, "Surgery."METHODS: Content and frequency analyses of 2,132 articles published in "Surgery" from 2006 to 2017 were conducted. Two medical doctors who majored in surgery and anesthesiology perused the articles and compiled the diseases being elucidated in each article. The diseases described in each article were stratified into 13 surgical subspecialties.
    RESULTS: Articles from "Surgery," similar to articles from the Western surgical community, also covered a wide variety of surgical diseases from different subspecialties, and the number of publications continued to grow consistently. Moreover, a number of studies focused on the fields of orthopedics and general surgery dealing with benign diseases. Some articles focused on minimally invasive surgeries using laparoscopy.
    CONCLUSION: The studies published in the North Korean journal "Surgery" encompass various clinical areas, but their quality is unclear.

    Women are underrepresented in major US sleep societies recognition awards.
    Samira Naime, Elias G Karroum.
      STUDY OBJECTIVES: To investigate gender distribution of US sleep professionals who received major recognition awards over a forty-year period from the two national sleep societies: the American Academy of Sleep Medicine (AASM) and the Sleep Research Society (SRS).METHODS: We reviewed and analyzed the publicly available lists of sleep recognition awards recipients from the AASM and the SRS websites. The primary outcome measures were the overall proportion of individual sleep recognition awards given to US men and women sleep professionals and the trend over time (1981-2020) analyzed by decade using the Cochran-Armitage test.
    RESULTS: Seven major sleep recognition awards (four by the AASM; three by the SRS) were identified over 40 years. There were overall 164 individual sleep recognition awards presented by the two sleep societies to US sleep professionals, including 136 (82.9%) awarded for men and only 28 (17.1%) awarded for women. The analysis of the sleep recognition awards over time by decade revealed a significant increasing trend (p < 0.0001) in the proportion of awards recognizing women relative to men with a progression from 0.0% in the 1980s, to 3.4% in the 1990s, to 13.1% in the 2000s, and to 31.7% in the 2010s.
    CONCLUSIONS: US women sleep professionals were historically underrepresented in major sleep recognition awards, with a reduction in the gender gap in the last ten years. The reasons behind gender inequality in sleep recognition awards remain unclear and deserve further investigation.

    ScanBious: Survey for Obesity Genes Using PubMed Abstracts and DisGeNET.
    Svetlana Tarbeeva, Ekaterina Lyamtseva, Andrey Lisitsa, Anna Kozlova, Elena Ponomarenko, Ekaterina Ilgisonis.
      We used automatic text-mining of PubMed abstracts of papers related to obesity, with the aim of revealing that the information used in abstracts reflects the current understanding and key concepts of this widely explored problem. We compared expert data from DisGeNET to the results of an automated MeSH (Medical Subject Heading) search, which was performed by the ScanBious web tool. The analysis provided an overview of the obesity field, highlighting major trends such as physiological conditions, age, and diet, as well as key well-studied genes, such as adiponectin and its receptor. By intersecting the DisGeNET knowledge with the ScanBious results, we deciphered four clusters of obesity-related genes. An initial set of 100+ thousand abstracts and 622 genes was reduced to 19 genes, distributed among just a few groups: heredity, inflammation, intercellular signaling, and cancer. Rapid profiling of articles could drive personalized medicine: if the disease signs of a particular person were superimposed on a general network, then it would be possible to understand which are non-specific (observed in cohorts and, therefore, most likely have known treatment solutions) and which are less investigated, and probably represent a personalized case.
