      BACKGROUND: Femoroacetabular impingement (FAI) has attracted increasing attention over the past few decades. We aim to evaluate FAI research and predict research hot spots quantitatively and qualitatively.METHODS: The publications in FAI research between 2000 and 2019 were assimilated from the Web of Science Core Collection of Clarivate Analytics. The retrieved data were evaluated by the bibliometric method. Software CiteSpace 5.7.R1, VOSviewer 1.6.15, and the Online Analysis Platform of Literature Metrology ( were used to analyze and identify the hot spots and trends in this field.
    RESULTS: A total of 2471 originals articles that fulfilled the study requirements were obtained. The number of manuscripts on FAI has experienced rapid growth, especially after 2009. The United States of America was the leading country for publication and to the collaboration network. FAI, osteoarthritis, hip arthroscopy, labral reconstruction, pathomorphology, outcome, rehabilitation, and joint cartilage are some of the high-frequency keywords in co-occurrence cluster analysis and cocited reference cluster analysis. Burst detection analysis of top keywords revealed that outcomes, instability, labral reconstruction, adolescent, and risk factor were newly emerged research hot spots.
    CONCLUSION: The understanding of FAI has been improved significantly during the past two decades. Present studies focused on identifying the optimal method to treat labral pathology, outcome assessment of either surgeries or conservative managements, and predicting midterm and long-term outcomes. Together these studies exert critical implications for decision-making and management for FAI.

      OBJECTIVE: To assess the participation of women in publications of dental journals with a high impact factor.METHODS: Articles published in 2016, 2011, and 2006 in 10 dental journals chosen for their highest impact factors in each dental fields were included in this research. Articles-related variables collected included the country of origin of each author, the type of study, and gender of the researchers. Gender was examined through PubMed, Scopus, ResearchGate, and respective affiliated institutions. Furthermore, a website designed to discover the gender of names was used when the previous alternatives were not conclusive. Forward stepwise Poisson regression models were used for data analysis.
    RESULTS: A total of 3365 studies were included in the first authorship analysis and 3398 in analysis related to last authorship. The prevalence of women as first authors was 37.2% (confidence interval (CI) 95% 34.5-37.5) and as last authors was 22.6% (CI 95% 21.3-23.9). Having a woman as the last author increased the presence of women in the first author position in scientific dental articles by 16% (prevalence ratio = 1.16, CI 95% [1.04-1.29]). The year of publication, journal, and region of the author were associated with an increase in the prevalence of women as last authors. From 2006 to 2016, the prevalence of women as last authors increased by 61%. Despite these trends, women were still underrepresented in science in the evaluated period.
    CONCLUSIONS: There are meaningful gender inequalities in publications of scientific dental papers. Encouraging women to lead research groups can reduce the inequities observed in the present study.

      Background: With the popularization of knee replacement surgery in the treatment of the advanced lesions of knee joint, the amount of knee revision surgery is increasing unceasingly. Meanwhile, the continuous introduction of new clinical concepts and new technology poses a challenge to researchers and surgeons. Our study aims to inform the future scientific research and clinical treatment, by investigating the hot spots and trends of the knee revision research field with the method of bibliometric analysis.Methods: Publications on knee revision included in the database of Web of Science Core Collection (WoSCC) between 2000 and 2018 were reviewed and MeSH terms of them were extracted from PubMed. Online bibliometric analysis website (, two pieces of software called "CiteSpace" and "Bibliographic Item Co-Occurrence Matrix Builder" (BICOMB) were used to analyze the publications reviewed at quantitative level. Another piece of software called "gCLUTO", was used to investigate the hot spots with visualization techniques at qualitative level.
    Results: A total of 906 publications were retrieved between 2000 and 2018. There is an increasing number of publications, from 15 in 2000 to 86 in 2018. Journal of Arthroplasty is the leading journal which has the most publications on knee revision. The United States has been the biggest contributor. Mayo Clinic became the leader among the institutions which have conducted correlational researches. David G. Lewallen, Robert L. Barrack and Michael A. Mont should be regarded as the scholars who have made outstanding contribution. Hot spots were summed up in six clusters, respectively, the solutions for infection, prostheses, the adverse effects, the surgical techniques, epidemiological characters, and the pathophysiology of the revision knee.
    Conclusions: We found a growing trend in knee revision research and extracted the most contributive researchers, institutions, countries, journals, and most-cited articles worldwide. The solutions for complications, surgical applications and analysis for epidemiological characters have been the hot spots. Multi-disciplinary integration is becoming the time-trend of hot spots. Minimally invasive and navigation are directions of revision surgery. They together constitute a solid foundation and set up a fingerpost for the future scientific research and clinical treatment.

      BACKGROUND AND AIM OF THE WORK: Despite Allied Health Professions (AHPs) represent a substantial part of workforce within the health system and they might give a relevant contribution to research, literature on publication productivity of AHPs working in non-research/academic institutions is scarce. The aim of this investigation was to provide point prevalence of AHPs working in a non- research/academic setting who have written at least one article published in indexed journals, in order to describe their scientific productivity.METHODS: A descriptive cross-sectional study was carried out of AHPs working in large Local Health Authority in Italy, who published in journals indexed in Scopus and/or PubMed. H-index, publications and citations number, journal name, publication year, and journal Impact Factor were extracted.
    RESULTS: Fifty-two AHP workers were identified as authors, having published 105 articles between 1993 and 2019. The number of papers increased over the years (p < .001). Published papers in journals with Impact Factor were 67.6% (n = 71) of the total, with a median Impact Factor = 2.676 (range = 0.583 - 59.102). The median number of citations was 4 (range = 0 - 99). The prevalence among units ranged from 0.8% to 5.0%, 2.9% in the whole department. There were not significant differences in number of articles (p = .138), citations received (p = .337), and H-Index (p = .661) among units.
    CONCLUSIONS: In the Local Health Authority under investigation, publication productivity of AHPs workers was found to be low, although it is increasing over time, with no significant differences among units. Further investigations should be carried out to link these results with authors' information and organizational characteristics to study the relationship between authors' profiles and publication productivity.

      Background: Given that acupuncture treatment for pain has gradually been accepted by researchers from various countries. However, few bibliometric analyses have been performed on the published articles. The objective of this research was to review its application for pain in recent 10 years and analyze, demonstrate and evaluate the trends, major research hotspots and frontier areas.Methods: The Web of Science retrieved literature from 2010 to 2020 on acupuncture for pain. The CiteSpace and Excel were used to analyze annual volumes of publications, journals, cited journals, countries, institutions, authors, cited authors, references and keywords and to draw collaborative networks and reference co-citation network maps.
    Results: The search finally included 4227 related studies. Results show that the number of annual publications has been increasing gradually. Evid Based Complement Alternat Med (366) was the most productive journal, while Pain (2270/0.04) ranked first in terms of frequency and centrality of cited journals, respectively. Among countries/institutions, the China (1252) and the Kyung Hee University (228) ranked first. Lee MS (51 articles) was the most effective author while MacPherson H (577) was the most cited author. The most frequently cited reference was a systematic review of individual patient data on acupuncture for chronic pain (322). "Burden" was identified as a frontier research item for 2017-2020.
    Conclusion: This study provides a new and in-depth understanding of current acupuncture used for the treatment of pain. We anticipate that this study will stimulate international cooperation among research teams to advance the field.

      BACKGROUND: Artificial pancreas is a well-known research topic devoted to achieving better glycemic outcomes that has been attracting increasing attention over the years. However, there is a lack of systematic, chronological, and synthesizing studies that show the background of the knowledge generation in this field. This study implements a bibliometric analysis to recognize the main documents, type of publications, research categories, countries, keywords, organizations, and authors related to this topic.METHODS: Web of Science core collection database was accessed from 2000 to 2020 in order to select high-quality scientific documents based on a specific search query. Bibexcel, MS Excel, Power BI, R-Studio, VOSviewer, and CorText software were used for a descriptive and network analysis based on the local database obtained. Bibliometric parameters as the h-index, frequencies, co-authorship and co-ocurrences were computed.
    RESULTS: A total of 756 documents were included that show a growing scientific production on this topic with an increasing contribution from engineering. Outstanding authors, organizations, and countries were identified. An analysis of trends in research was conducted according to the scientific categories of the Web of Science database to identify the main research interests of the last 2 decades and the emerging areas with greater prominence in the coming years. A keyword network analysis allowed to identify the main stages in the development of the AP research over time.
    CONCLUSIONS: Results reveal a comprehensive background of the knowledge generation for the AP topic during the last 2 decades, which has been strengthened with international collaborations and a remarkable interdisciplinarity between endocrinology and engineering, giving rise to a growing number of research areas over time, where computer science and medical informatics stand out as the main emerging research areas.

      OBJECTIVE: The citation history of a published article reflects its impact on the literature over time. We conducted a comprehensive bibliometric analysis to identify the most cited papers on CHD in children.METHODS: One-hundred and ninety journals listed in Journal Citation Reports were accessed via Web of Science. Publications with 250 or more citations were identified from Science Citation Index Expanded (1900-2020), and those relating to structural CHD in children were reviewed. Articles were ranked by citation count and the 100 most cited were analysed.
    RESULTS: The number of citations ranged from 2522 to 309 (median 431, IQR 356-518), with 35 published since 2000. All were written in English, most originated from the United States (74%), and were published in cardiovascular journals, with Circulation (28%) the most frequent. There were 86 original research articles, including 50 case series, 14 cohort studies, and 10 clinical trials. The most cited paper was by Hoffman JI and Kaplan S on the incidence of CHD. Thirteen authors had 4 or more publications in the top 100, all of whom had worked in Boston, Philadelphia, San Francisco, or Dallas, and the most prolific author was Newburger JW (9 articles).
    CONCLUSIONS: Citation analysis provides a historical perspective on scientific progress by assessing the impact of individual articles. Our study highlights the dominant position of US-based researchers and journals in this field. Most of the highly cited articles remain case series, with few randomised controlled trials in CHD appearing in recent years.

      BACKGROUND: The past decade has witnessed the preliminary development of pre-hospital emergency. We analyzed the scientific output related to pre-hospital emergency in the past two decades, aiming to evaluate the publication status of the literature related to pre-hospital emergency through bibliometrics analysis, and hope to provide enlightenment of trends and hotspots for the development of pre-hospital emergency.METHOD: By web of science, all literature on pre-hospital emergency from 2000 to 2 October 2020 was retrieved and screened by two researchers. Excel, Social Sciences Statistics Package (SPSS, version 24) and software GraphPad Prism 8 were used to analyze the publication trend in related fields. Besides, VOSviewer, Citespace were also applied to visualize the research trends and study the co-occurring keywords in pre-hospital emergency.
    RESULTS: As of 2 October 2020, a total of 1839 pre-hospital emergency publications with total citation of 32800 times were identified. The United States accounted for the largest number of publications (36.7%) and the highest number of citations (12825), but its H-index was fourth (20.17). In the aspects of journals and articles, Prehospital Emergency Care is the most published journal in pre-hospital emergency (256), while the articles from Smith K presented the highest citation frequency (751). We can also obtain the information that the overall trend is upward, and developed countries contribute most. "Complications" is a hot research field in intensive care. In the identification research cluster, "acute ischemic stroke" was determined to be the hotspot, while "secondary outcome" was the new trend in the first-aid cluster. As for the management, "embase" was noted as new topics.
    CONCLUSION: In the past decade, researches on pre-hospital emergency has increased rapidly. However, the related articles were mainly published in developed countries, the United States has absolute advantages especially. Moreover, first-aid studies may become hotspots in the near future.

      The African Academy of Sciences (AAS) is the preeminent science academy on the African continent, but there is currently no information on the academic productivity of the fellowship members. This study investigated the bibliometric parameters of the AAS medical and health sciences fellows. The demographic information (year of induction, gender, and region of employment in Africa) of the 80 medical and health sciences fellows were obtained from the AAS website. Subsequently, the bibliometric information (total number of publications, H-index scores, citation, and co-authorship counts) were extracted from the Scopus database. The majority of the fellows were from the East (36%) and West (33%) African regions (χ2 = p < 0.001); the North (6%) and Central (4%) regions were vastly underrepresented. Although only 34% of the AAS fellows were women, there was no statistically significant difference (p > 0.05) in the bibliometric parameters of both genders. The year of induction as a fellow and region of employment in Africa significantly (p < 0.05) influenced the bibliometric parameters. For all the fellows combined, their H-index mean (SD) score is 27.9 (17.0), while the median score for the total number of publications is 100, H-index is 27.5, and the citation and co-authorship count is 2,894 and 446, respectively. The fellows from the West African region had the highest number of publications (Mean = 212), citations (Mean = 9,437), and co-authorship count (Mean = 975), and the South African fellows had the highest H-index score (Mean = 40.8). The data presented provide insight into the bibliometric productivity of African scientists compared with their peers from other science academies around the world. Similarly, the data may assist burgeoning scientists aspiring to be AAS fellow set realistic goals toward achieving the stipulated H-index benchmarks.

      Background: We aimed to comprehensively analyze all the literature related to aortic dissection (AD) in the past decade using Web Scrapping technology from PubMed, revealing the research dynamics in this field.Methods: Data were retrieved and downloaded from PubMed with search strategy as "(aortic dissection [Title/Abstract]) AND (2010[EDAT]: 2020[EDAT])". Information on the PMID, journal name, title, number of citations, publication year, authors, affiliations, abstract, study type, and keywords of the research was recorded.
    Results: A total of 7,470 publications were identified. Most of the articles were published in J Thorac Cardiovasc Surg; Japan was the country with the largest publications number; the USA was far ahead of other countries regarding the highly cited studies; Yale University and Baylor College of Medicine took the first place for publishing most of the highly cited articles; the most frequently cited article is the 2014 ESC Guidelines on the diagnosis and treatment of aortic diseases; most of the clinical trials were published on J Vasc Surg; John A. Elefteriades ranked first by cumulative publication numbers; Christoph A. Nienaber took the lead by both cumulative citations and impact factors; Dianna M. Milewicz was the only female researcher on all the three ranking lists; the most common keywords in aortic dissection were Treatment Outcome and Retrospective Studies.
    Conclusions: This study provides interesting insights into the AD scientific landscape in recent 10 years and generates some objective evidence for comprehensive understanding and evaluation of this field. This investigation may ultimately inform managers, researchers and policymakers.

      Importance: A significant portion of neurology literature is published in general medicine journals. Despite this, a detailed examination of publication patterns of neurology articles in these journals has not yet been carried out.Objective: To examine the publication patterns of neurology articles in general medicine journals during a 10-year period using a bibliometric approach.
    Design, Setting, and Participants: This cross-sectional bibliometric analysis identified the top 5 general medicine journals using the 2017 Journal Citations Report. Four other medical subspecialties (ie, immunology, endocrinology, gastroenterology, and pulmonology) were selected for comparison of publication patterns with neurology. Using MEDLINE, the 5 journals were searched for articles published between 2009 and 2018 that were indexed with the following MeSH terms: nervous system diseases, immune system diseases, endocrine system diseases, gastrointestinal diseases, and respiratory tract diseases. Data analysis was conducted from February 2019 to December 2020.
    Main Outcomes and Measures: Publications were characterized by journal, specialty, and study design. These variables were used for comparison of publication numbers.
    Results: The general medicine journals with the 5 highest journal impact factors (JIF) were New England Journal of Medicine (NEJM; JIF 79.3), Lancet (JIF 53.3), JAMA (JIF 47.7), BMJ (JIF 23.6), and PLOS Medicine (JIF 11.7). Our bibliometric search yielded 3719 publications, of which 1098 (29.5%) were in neurology. Of these 1098 neurology publications, 317 (28.9%) were published in NEJM, 205 (18.7%) in Lancet, 284 (25.9%) in JAMA, 214 (19.5%) in BMJ, and 78 (7.1%) in PLOS Medicine. Randomized clinical trials were the most frequent neurology study type in general medicine journals (519 [47.3%]). The number of publications in each of the other specialties were as follows: immunology, 817; endocrinology, 633; gastroenterology, 353; and pulmonology, 818.
    Conclusions and Relevance: The results of this study provide some guidance to authors regarding where they may wish to consider submitting their neurology research. Compared with other specialties, neurology-based articles are published more frequently in general medicine journals.

      INTRODUCTION: Our goal in this study was to determine female representation on editorial boards of high-ranking emergency medicine (EM) journals. In addition, we examined factors associated with gender disparity, including board members' academic rank, departmental leadership position, h-index, total publications, total citations, and total publishing years.METHODS: In this retrospective study, we examined EM editorial boards with an impact factor of 1 or greater according to the Clarivate Journal Citations Report for a total of 16 journals. All board members with a doctor of medicine or doctor of osteopathic medicine degree, or international equivalent were included, resulting in 781 included board members. We analyzed board members' gender, academic rank, departmental leadership position, h-index, total publications, total citations, and total publishing years.
    RESULTS: Gender disparity was clearly notable, with men holding 87.3% (682/781) of physician editorial board positions and women holding 12.7% (99/781) of positions. Only 6.6% (1/15) of included editorial board chiefs were women. Male editorial board members possessed higher h-indices, total citations, and more publishing years than their female counterparts. Male board members held a greater number of departmental leadership positions, as well as higher academic ranks.
    CONCLUSION: Significant gender disparity exists on EM editorial boards. Substantial inequalities between men and women board members exist in both the academic and departmental realms. Addressing these inequalities will likely be an integral part of achieving gender parity on editorial boards.

      BACKGROUND: Acupuncture therapy has a wide range of applications in obstetrics and gynecology, especially for patients with reproductive issues, irregular menstruation, dysmenorrhea, and pelvic inflammatory disease. In recent decades, acupuncture therapy has gradually attracted the attention of professionals in China and overseas due to its beneficial effects, and has been the focus of many studies. This study aimed to conduct a statistical analysis of the relevant literature to understand the current application and research status of acupuncture in obstetric and gynecologic diseases.METHODS: A search of the SCI-EXPANDED database in the Web of Science Core Collection (WOSCC) was performed. Search strategy included two formulas: #1 WC=Obstetrics & Gynecology, limited: index =SCI-EXPANDED time span=all years; #2 subject: (ACUPUNCTURE-MOXIBUSTION) OR subject: (ACUPUNCTURE) OR subject: (MOXIBUSTION), limited: index=SCI-EXPANDED time span=all years. The final result was acquired by searching #1 AND #2. CiteSpace software was used to analyze and visualize the annual distribution of articles, and the distributions of disciplines, countries/institutions, journals, and authors. Keywords were used to infer the application of acupuncture in obstetrics and gynecology.
    RESULTS: A total of 593 research literatures, including 323 original articles, were retrieved. Since 1972, the number of literatures has shown a general increase. Studies on reproductive medicine accounted for the highest proportion of the retrieved literatures (139, 23.44%). The United States (25.5%), China (14.0%), Germany (7.6%), Australia (7.3%), and Sweden (7.1%) were the main contributors. The centrality index showed that the United States (0.19), the United Kingdom (0.19), and Germany (0.16) had the closest cooperation. The retrieved literatures covered 15 subdivision areas, including menstruation, embryo transfer, production, and pelvic pain. Obstetrics & Gynecology, Cochrane Database of Systematic Reviews, and American Journal of Obstetrics and Gynecology were found to be the most influential journals. The most frequently cited keywords were acupuncture (intensity =5.5326), low back pain (intensity =5.0506), and pregnancy (intensity =4.7016).
    CONCLUSIONS: Acupuncture is receiving an increasing amount of attention in obstetrics and gynecology, and international cooperation in research in this field is also increasing.

      Although the number of food governance-related studies increased rapidly in the recent decade, the current academic research still lacked systematic integration of food safety governance. To clarify the development trends of research therein, this study summarized research articles concerning food safety governance by the Web of Science Core Collection. An in-depth bibliometric analysis was then conducted through CiteSpace to summarize the current characters and hot spots of food safety governance research, and predicted future research trends. Results showed that food safety governance was multidisciplinary, which included environmental science, food science, economics, and agriculture. The United States had the largest number of relevant articles, and Wageningen University was the most influential scientific research institution. Among all the journals in this field, Food Policy ranked the first in publication volume and co-citation frequency. The development of food safety governance research was divided into three processes, namely the separate formulation of the standards for public and private sectors, the joint implementation of these standards, and co-governance by multiple sectors. The most popular research hot spots in this field were food safety policy integration and public-private partnership of food safety governance. Lower- and middle-income countries focused more on food supply and food system design, and regrettably not on food safety. Higher-income countries cared more about food safety and food nutrition. Besides, researchers of higher-income countries also concentrated on consumers' voices in participating in food safety governance. Food safety co-governance, online food governance, the willingness to buy safe food, and food safety governance under pandemics were considered as future research directions.

      PURPOSE: To compare social media attention and citation rates between infographics (visual abstracts) and original research articles.METHODS: All infographics in 2019 from electronic versions of Arthroscopy were matched by topic to articles in the "Original Research" section of the journal in a 4:1 ratio within the same year. The primary outcome was the Altmetric Attention Score (AAS), a cumulative measure of social media attention from various platforms such as Twitter and Facebook. Secondary outcomes included citation rates, article characteristics, and number of shares on social media platforms. Independent t-tests and chi-squared analyses were used to compare primary and secondary outcomes between infographics and control articles. Multivariate linear regression analysis was performed to determine the association between article type and social media attention while controlling for bibliometric characteristics.
    RESULTS: A total of 60 matched research articles (n=48, 80.0%) and infographics (n=12, 20.0%) published in 2019 in Arthroscopy were included. The mean AAS among all infographics was 29.75 + 32.84 (range, 3-118), while the mean AAS among all control research articles was 5.75 + 8.90 (range, 0-41), representing a statistically significant difference (p<0.001). Infographics had significantly more Twitter mentions (100% vs. 70.8%, p<0.001) and Facebook mentions (75% vs. 6.2%, p<0.001) compared to original articles. Multivariate linear regression analysis demonstrated a statistically significant and positive association between AAS and article type, with an additional mean increase in the AAS of 33.7 (95% confidence interval, 11.6 - 50.6; p=0.003) for every infographic article compared to an original research article. The mean citation rate among all infographics was 2.4 + 2.4 (range, 0-7), while the mean citation rate among all control research articles was 2.2 + 4.0 (range, 0-27), which was not a significant difference (p=0.69).
    CONCLUSION: Infographics resulted in significantly greater altmetric attention scores and social media attention in comparison to original research articles of similar topics. We recommend the routine creation of infographics by journals to increase the social media attention that their research and chosen topics of interest receive. However, viewers of infographics should read them out of interest, but turn their attention towards the original article or a source of more detailed information prior to making changes in clinical decision-making or practice as they can be over-simplified.
    CLINICAL RELEVANCE: Infographics are an increasingly used by journals as a form of depicting research findings from select studies. By producing infographics, journals may increase the amount of social media attention received for a particular study or topic of interest.

      BACKGROUND: There are no reports on global research status of gastroenterology and hepatology (GI). This study was conducted to reveal the current global research status and trends in GI.METHODS: Articles published during 2009 to 2018 in international GI journals were retrieved from the PubMed database. The top 20 countries by output were determined. The gross domestic product (GDP) of each country was also retrieved to figure out the correlation between outputs in GI and economy. The 5 highest-ranking countries were compared in the number of total articles, articles per capita, articles published in top journals, the accumulated impact factor (IF), and average IF. Total articles and articles per capita of the 5 countries were conducted time-trend analysis. The frequently-used terms in titles and abstracts of articles published in 2009 and 2018 were retrieved to conduct co-occurrence analysis to figure out the change of research highlights in GI.
    RESULTS: A total of 120,267 articles were included, of which 116,485 articles were from 20 highest-output countries. There was a positive correlation between output and GDP (r = 0.921, P < .001). The USA, Japan, China, Italy, and the UK were the 5 highest-ranking countries. The USA was the largest contributor with 26,215 articles, accounting for 17.4% of the total, but with no significant increasing trend (P = .122). Other 4 countries all showed increasing trends (all P < .001). For articles per capita, Italy ranked 1st among the 5 countries with 1591.0 articles per 10 million. The USA showed a decreasing trend (P = .026), other 4 countries all showed increasing trends (all P < .001). The UK had the highest average IF (6.685). For change of research highlights, it is more inclined to research of endoscopy, inflammatory bowel diseases, and nonalcoholic fatty liver disease.
    CONCLUSION: It is delightful that the global research output in GI field would be continuingly increased as the major highest-output countries showed increasing trends. However, the developing countries fell behind both in quantity and quality when compared with developed countries.

      Familial Mediterranean Fever (FMF) is an inherited autoinflammatory disease. One of the feared complications of FMF, amyloidosis is often correlated with an increased mortality rate. The severity of the disease is linked with different mutations in the MEFV gene that may favor different outcomes (amyloidosis, Bechet's disease…). Although several countries worldwide contribute remarkably to research related to FMF, Arab countries make up only a small part of this contribution. This study aims to estimate numerically the contribution of the Arab world to research conducted on FMF. PubMed is used to quantitate the number of FMF-related articles published by each Arab country from 2004 till 2019. The retrieved numbers are normalized with respect to each country's average population and average Gross Domestic Product (GDP) and are also compared to those of some non-Arab countries having high FMF prevalence. In comparison with some non-Arab countries, the Arab world has a minor contribution of 3.80% to the total FMF-related publications, faced by 24.93% solely by Turkey. Out of total research done by Arab countries, FMF-related articles constitute no more than 0.133%. When normalized against the average population, Tunisia ranks first, followed by Lebanon. Similarly, normalizing the retrieved numbers of articles against average GDP shows that Tunisia and Lebanon come first and second, respectively. Only 8 Arab countries published a total of 13 articles concerning amyloidosis which makes 4.7% of the total Arabic FMF published articles. This study reflects an undoubtable need for more research to be conducted on FMF by the Arab countries, which suffer greatly from immense shortage in research productivity, due to the many obstacles and limitations these countries face every day.

      PURPOSE: Both-bone forearm fractures in the adult population frequently and usually necessitate an operative reduction. The purpose of this study was to identify the 50 most cited publications regarding both-bone ORIF and evaluates their level of evidence to help guide the best treatment and management practices, as well as gauge the current level of inquiry into this topic.METHODS: The Clarivate Analytics Web of Knowledge Database was queried. The top 50 most cited articles identified as relevant were analyzed. Aggregate citation counts, citation density, type of study, and level of evidence were documented for each of the 50 articles. Abstracts from the last decade of prominent orthopaedic meetings were analyzed to determine the current level of inquiry into this area.
    RESULTS: The initial search yielded 408 results. There were 27 articles published before 2000 and 23 after. The total summation of citations for the top 50 articles totaled 2062. Each study was classified according to its study design and level of evidence. The most common was case series (34). Level IV studies were most numerous (34). Since 2010, the subject of both-bone forearm fracture ORIF was presented 8 times at prominent orthopaedic conferences.
    CONCLUSION: Our work demonstrated 54% of top-50 studies are pre-2000 and the majority are Level IV evidence. Additionally, despite the established treatment, there is active inquiry into this topic. Higher quality research can be helpful to validify treatment and management options.

      The present editorial 2020 continues the series of status reports in Environmental Earth Sciences (EES) in previous years 2017 and 2019 (Kolditz et al. in Environ Earth Sci 77: 8, 2018, Kolditz et al. in Environ Earth Sci 79: 11, 2020). The year 2020 coming to an end was heavily influenced by the COVID-19 pandemic affecting all areas of life including research work and, therefore, scientific publishing as well ("Introduction"). One bright spot which shows longevity of journals that produce a quality product is that Environmental Earth Sciences (EES) is celebrating its 45th anniversary of publication. To this extent EES continues the tradition to honor the most cited papers contributing to the 2020 Impact Factor (IF) ("Highly and most cited topics") and provide information on the current status of EES as well as an outlook to 2021 ("Progress report").

      BACKGROUND: Antimicrobial resistance (AMR) is a global challenge that requires a "One Health" approach to achieve better public health outcomes for people, animals, and the environment. Numerous bibliometric studies were published on AMR in humans. However, none was published in food-producing animals. The current study aimed at assessing and analyzing scientific publications on AMR in food-producing animals.METHOD: A validated search query was developed and entered in Scopus advanced search function to retrieve and quantitatively analyze relevant documents. Bibliometric indicators and mapping were presented. The study period was from 2000 to 2019.
    RESULTS: The search query retrieved 2852 documents. During the period from 2015 to 2019, approximately 48% of the retrieved documents were published. The article about the discovery of plasmid-mediated colistin resistance in pigs received the highest number of citations (n = 1970). The Journal of Food Protection (n = 123; 4.3%) ranked first in the number of publications while the Applied and Environmental Microbiology journal ranked first in the number of citations per document. The USA led with 576 (20.2%) documents followed by China (n = 375; 13.1%). When the number of publications was standardized by income and population size, India (n = 51.5) ranked first followed by China (n = 38.3) and Brazil (n = 13.4). The growth of publications from China exceeded that of the USA in the last 3 years of the study period. Research collaboration in this field was inadequate. Mapping author keywords showed that E. coli, Salmonella, poultry, Campylobacter, chicken, cattle, and resistant genes were most frequent. The retrieved documents existed in five research themes. The largest research theme was about AMR in Salmonella in food-producing animals. The most recent research theme was about the dissemination and molecular transfer of AMR genes into the environment and among different bacterial strains.
    CONCLUSION: Hot spots of research on AMR in food-producing animals match the world regions of reported hot spots of AMR in animals. Research collaboration in this field is of great importance, especially with low- and middle-income countries. Data on AMR need to be collected nationally and internationally to implement the "One Health" approach in the fight against AMR.

      BACKGROUND: Despite women constituting over half of new doctors, gender disparity remains an issue. Surgery has shown particularly slow progress towards gender parity. This study aimed to quantify gender representation within editorial boards of the highest ranking international general surgery journals.METHODS: Surgical journals were collated using two indices: SCImago Journal Rank (SJR) and Journal Impact Factor (JIF). Non-general surgery journals were excluded. Journals were contacted, requesting gender editorial team demographics. Editorial board data were collected via journal websites on 28 November 2019.
    RESULTS: The top 25 general surgery journals according to SJR and JIF ranking methods were determined, identifying 28 unique journals. Editorial board data were publicly available for 27 of these 28 surgical journals, and were examined. Women accounted for 20.2 per cent (568 of 2816) of total editorial board positions. Women constituted 11 per cent (4 of 36) of editor-in-chief positions, 32 per cent (29 of 92) of deputy editors, and 19.1 per cent (369 of 1935) of general editorial board positions.
    CONCLUSION: The findings demonstrate gender disparity within editorial boards of the most prominent general surgery journals.

      BACKGROUND: Academic productivity plays a growing role in professional advancement in academic medicine.OBJECTIVE: This study aims to assess academic productivity among spine surgeons. It investigates differences in h-indices between neurological and orthopedic spine surgeons.
    METHODS: The American Association of Neurological Surgeons (AANS) Neurosurgical Residency Training Program Directory provided names of US and Canadian academic neurological surgeons. The National Institutes of Health (NIH) Research Portfolio Online Reporting Tools (RePORT) database was consulted for the surgeons' NIH funding statuses. Scopus yielded the h-indices. Orthopedic spine surgeons were identified at the same institutions as the neurological spine surgeons, and their NIH funding statuses and h-indices were identified from the same databases. Statistical analysis investigated differences between the disciplines and across the categories of NIH funding reception, having a Ph.D., and academic rank.
    RESULTS: Two hundred fifteen neurological and 513 orthopedic spine surgeons met inclusion criteria. Neurological spine surgeons had a mean h-index of 21.16, and orthopedic spine surgeons had a mean h-index of 14.08 (p < 0.0001). Neurological surgeons with NIH funding had higher (p < 0.0001) h-indices (34.15) than those without it (19.29). Orthopedic surgeons with NIH funding had higher (p < 0.001) h-indices (42.83) than those without it (13.39). Analysis of Variance (ANOVA) showed that departmental chairmen and professors had higher h-indices than associate or assistant professors among neurological surgeons (p < 0.01) and orthopedic surgeons (p < 0.001).
    CONCLUSIONS: These results demonstrate the importance of the h-index in measuring academic productivity among neurological and orthopedic spine surgeons.

      A multi-dimensional construct of Catholic health care is examined using a bibliometric analysis of 181 scientific studies from the Web of Science database. Medical ethics, religion, and health services research by 418 authors from 26 countries reveals developments in the Catholic health care domain since 1973. Using VOSviewer, we map keyword clusters to reveal the structure of research on Catholic health care that transcends religious and secular literatures. The clusters mostly reflect clinical and ethical issues of reproductive health and the end of life, as well as the essence and the future of the Catholic identity from the theological and empirical perspectives.

      Science mapping is a methodology that combines quantitative analysis, classification, and visualisation to identify the composition and inter-relationships between bibliographic objects. Here, we used bibliometric science mapping to identify the overarching structure, evolution of research themes and research fronts, and geographic spread of body image research. We examined 2,783 keywords in 1,107 articles published in Body Image between 2004 and 2020, selected as being representative of body image research during this period. Co-occurrence analysis of the keywords enabled us to identify five general themes in the literature: "clinical and weight-related issues", "body image and disordered eating", "positive body image and objectification", "media effects", and "ethnicity/race". Burst analysis allowed us to identify research fronts in this research, with work on social media and positive body image in particular being identified as emergent. Finally, co-author analysis indicated that body image research networks are heavily focused on a small handful of nations, although there is evidence of a recent shift toward greater geographic spread. Our results, and the provision of interactive maps and extensive tables, should allow readers to examine connections between research clusters and areas, generate novel research ideas, and more fully understand the evolution and future trajectories of body image research.

      Using a large dataset of marathon runners, we estimate country- and gender-specific proxies for overconfidence. Subsequently, we correlate them with a number of indices, including various measures of gender equality. We find that in less gender-equal countries both males and females tend to be more self-confident than in more equal countries. While a substantial gender gap in overconfidence is observed, it only correlates with some sub-indices of gender equality. We conclude that there is likely a weak relationship between OC gender gap and gender inequality.

      The publication rate (PR) of full-text articles after presentation at medical society meetings varies widely. The purpose of this study is (1) to determine the PR of abstracts presented at the Dutch Arthroscopy Society's (NVA) annual meeting from 2006 until 2016, (2) to determine the time between presentation and publication, and (3) to review the known literature on the PR of orthopaedic scientific meetings. We retrospectively reviewed the programs of the NVA annual meetings from 2006 to 2016. All podium presentations reported were included. The search for subsequent journal publication was performed using PubMed, EMBASE, and Google Scholar databases. A systematic literature search was performed in PubMed. All studies regarding the publication rates of orthopaedic scientific meetings were included. From 2006 to 2016 a total of 131 papers were presented at the NVA annual meetings, of which 83 were published as full text articles (63%). The mean time to publication was 16.5 months. The overall PR at orthopaedic scientific meetings ranges from 21% to 71%.
