       AIMS: How often a medical article is cited is important for many people because it is used to calculate different variables such as the h-index and the journal impact factor. The aim of this analysis was to assess how the citation count varies between Web of Science (WoS), Scopus, and Google Scholar in the current literature.
    METHODS: We included the top 50 cited articles of four journals ESC Heart Failure; Journal of cachexia, sarcopenia and muscle; European Journal of Preventive Cardiology; and European Journal of Heart Failure in our analysis that were published between 1 January 2016 and 10 October 2019. We recorded the number of citations of these articles according to WoS, Scopus, and Google Scholar on 10 October 2019.
    RESULTS: The top 50 articles in ESC Heart Failure were on average cited 12 (WoS), 13 (Scopus), and 17 times (Google Scholar); in Journal of cachexia, sarcopenia and muscle 37 (WoS), 43 (Scopus), and 60 times (Google Scholar); in European Journal of Preventive Cardiology 41 (WoS), 56 (Scopus), and 67 times (Google Scholar); and in European Journal of Heart Failure 76 (WoS), 108 (Scopus), and 230 times (Google Scholar). On average, the top 50 articles in all four journals were cited 41 (WoS), 52 (Scopus, 26% higher citations count than WoS, range 8-42% in the different journals), and 93 times (Google Scholar, 116% higher citation count than WoS, range 42-203%).
    CONCLUSION: Scopus and Google Scholar on average have a higher citation count than WoS, whereas the difference is much larger between Google Scholar and WoS.

    What happens to global health research: analysis of the full-length publication rates of research abstracts presented at two major global health conferences.
    Praveen P Rajaguru, Ajay Premkumar, Neil P Sheth.
       BACKGROUND: Global health research has been expanding rapidly. The Consortium of Universities for Global Health (CUGH) and Global Health and Innovation Conference (GHIC) are the two major conferences for global health research. It is unclear how much of the presented research goes on to full-length publication.
    OBJECTIVES: This study sought to determine publication rates and journals of CUGH and GHIC research.
    METHODS: A total of 1449 abstracts from CUGH and GHIC from 2014 to 2015 were searched by title, author and keywords using Google Scholar and PubMed. Publications were categorised according to WHO Sustainable Development Goal (SDG) categories.
    RESULTS: Research was published in 293 journals at a rate of 34.0%, within an average of 15.1 months. The 15 MEDLINE indexed global health journals accounted for just 5.5% of publications.
    DISCUSSION: Despite growth in global health research, publication rates from the two major conferences are low. The majority of publications in journals are not MEDLINE indexed global health journals. Improved publication and consolidation of global health research is critical.
    CONCLUSION: Global health conference publication rates are low. Effective dissemination is critical as the field grows. This may require increased publishing support, improved indexing and consolidation of global health research.

    Nanomaterials in the Environment: Research Hotspots and Trends.
    Chen Li, Guohe Huang, Guanhui Cheng, Maosheng Zheng, Nan Zhou.
      Research on the field of nanomaterials in environment has continued to be a major area of interest in recent years. To present the up-to-date progress in this field, a bibliometric study is conducted to analyze 7087 related publications in the Science Citation Index (SCI) core collection of Web of Science based on the expanded SCI. These publications are identified through using representative keywords in the research directions environment of the Web of Science. This study finds that China and the United States dominate the field; one difference between them is that China issued more independent publications and the United States issued more cooperative publications. In addition, the number of the related publications in Asian countries has exceeded that of European and American ones. A Chinese institution, the Chinese Academy of Sciences, has an absolute dominance in this field. Traditional high-impact environmental journals have ruled this field. The number of publications in the Energy and Environmental Science field has gradually decreased. In addition, a co-citation analysis shows that previous studies in this field can be divided into four major branches, and that graphene oxide and nano-inorganic particles are increasingly becoming research hotspots.

    Nathalie A Pena Polanco, Bridgette B McNally, Cynthia Levy, Elizabeth J Carey, Juvelyn Palomique, Tram T Tran.
       BACKGROUND: Studies suggest that gender differences in academic medicine exist. Men frequently have better measures of performance such as number of publications, number of citations, remuneration, and funding.
    AIMS: To evaluate whether a gender disparity in authorship exists.
    METHODS: We recorded the gender of first and senior authors of original papers, editorials/reviews from liver-related manuscripts in Gastroenterology, Hepatology, Transplantation, American Journal of Gastroenterology, and Liver Transplantation from January 2014 to 2016.
    RESULTS: Of 2424 articles reviewed, we excluded 232 (10%) due to inability to determine gender. Among papers analyzed, 72.0% were original and 28.1% reviews/editorials with 65.1% of first authors being male and 34.9% female. Only 20.3% of papers with multiple authors had a female senior author. The proportion of male first and senior authorship between original papers and reviews/editorials was comparable. 72% of original papers had a male as first or senior author, but only 28% females. 71% of review/editorial papers had a male as first or senior author, but only 29% females. When the senior author of an original paper was female, 47.1% of first authors were male and 52.9% female. When the senior author was male, 67.1% of first authors were male and 32.9% female (p < 0.00001).
    CONCLUSIONS: A significant gender difference exists in Hepatology publications. Female authorship mirrors the percentage of female AASLD membership; however, female senior authorship remains disproportionate. In general, funding for male authors is greater. Fewer women are first authors when the senior author is male, highlighting the importance of female mentorship in Hepatology.

      Introduction: Sepsis is an intractable disorder, which is associated with high risk of organ dysfunction and even death, while its pathogenesis remains largely unclear. Our study aims to study the research trend on sepsis and host immune response, and compare the contribution of publications from different countries, institutions, journals and authors. Materials and Methods: We extracted all relevant publications with regard to sepsis and immune response during 1999-2019 from Web of Science. GraphPad Prism 6, and VOSviewer software were used to collect and analyze the publication trend in related field. Results: We identified a total of 1225 publications with citation frequency of 40511 times up to March 30, 2019. The United States accounted for the largest number of publications (36.3%), 51.9% of total citations as well as the highest H-index (72). The sum of publications from China ranked the second, while the overall citations (1935) and H-index (22) ranked the eighth and the seventh, respectively. Journal of Shock had published most papers related to the topic on sepsis and immune response. Ayala A SA, has published the most papers in this field (31), while Hotchkiss RS presented with the most citation frequency (3532). The keyword "regulatory T cell" appeared most recently with an average appearing years of 2014.0. The "immunosuppression related research" seemed to be the hotspot in relevant scope. Conclusions: The United States made the most outstanding contribution within this important field. There is a mismatch between the quantity and quality of publications from China. Latest progress can be tracked in journal of Shock. Immunosuppression related researches may be hotspots in the near future.

    A bibliometric analysis of human strongyloidiasis research (1968 to 2017).
    Waleed M Sweileh.
       Background: Strongyloidiasis is a neglected tropical disease (NTD). It is commonly associated with poverty and poor hygiene. Strongyloidiasis poses an unseen global public health problem. The aim of this study was to assess and analyze peer-reviewed literature on human strongyloidiasis to shed light on the evolution, volume, important topics, and key players in the field of human strongyloidiasis.
    Methods: A validated bibliometric method was implemented using Scopus database for the study period from 1968 to 2017. The search strategy was developed based on keywords related to strongyloidiasis. Bibliometric indicators and visualization maps were presented.
    Results: In total, 1947 documents were found. Retrieved documents received 32,382 citations, an average of approximately 16.6 per document, and an h-index of 76. The most frequently encountered keywords in the retrieved literature focused on hyperinfection, diagnosis, prevalence, and ivermectin. The USA led with 540 (27.7%) documents followed by Brazil (139; 7.1%) and Japan (137; 7.0%). When research output was standardized by income and population size, India ranked first (12.4 documents per GDP/capita) followed by the USA (9.1 documents per GDP/capita). The most active journal involved in publishing articles was the American Journal of Tropical Medicine and Hygiene (95; 4.8%). In terms of institutions, the University of Ryukyus (Japan) was the most active with 62 (3.2%) publications, followed by the University of Pennsylvania with 54 (2.8%) publications.
    Conclusion: The volume, growth, and international research collaboration in human strongyloidiasis were inadequate given the long history of the disease, the large number of affected people, and the results obtained for other NTDs. Research in human strongyloidiasis needs to be strengthened and encouraged in endemic regions in Southeast Asia and Latin America. International research networking needs to be established to achieve the goals of Sustainable Development Goals in fighting and eradicating NTDs by 2030.

    Jialiang Hui, Li Wang, Ruiyu Liu, Changmou Yang, Haibo Zhang, Shuhua He, Zerong Chen, Anyang Wei.
      The incidence of premature ejaculation (PE) has been on the rise over the years. Thus, significant research efforts have been directed toward understanding the pathogenesis and hence treatment of PE. Here, we performed a comprehensive analysis of the worldwide trends in research outputs in the field of PE. This study investigated the universal findings of previous PE studies and the trending issues surrounding the condition. We employed the Web of Science Core Collection for data collection. The Excel (2016) and CiteSpace IV were used for information analysis. The information was categorized using journal names, institutions, research frontiers, citation reports, regions/countries, and authors. A sum of 886 publications concerning PE between 2008 and 2018 were identified as of July 6, 2019. The highest number of publications was identified in the Journal of Sexual Medicine published. The United States of America (USA) had the highest number of publications and H-index value. The highest co-citations were from Waldinger MD. The most common keyword was 'drug treatment'. A steady pattern was observed for PE publications done between the period of 2008-2018. Thus, the USA is at the forefront of research on PE research. The interesting advanced research frontiers were drug treatment, circumcision, and sertraline.

    David Zargaran, Alexander Zargaran, Sean Lobo, Zameer Shah.
      Knee Surgery is one of the most commonly performed orthopedic procedures, and a rapidly evolving area of research. A bibliographic analysis was conducted to explore the characteristics of the top 50 most cited articles in knee surgery. The Web of Science Core Collection Database was used to search for Knee AND Surgery, further refined for orthopedic surgery, yielding 1,660 articles. After inclusion and exclusion criteria were applied, the top 50 cited articles were statistically and thematically analyzed. Year of publication ranged from 1982 to 2014. The highest volume of research came from USA, with the Journal of Bone and Joint Surgery having the highest number of papers in the top 50. The most common theme of research was Knee Arthroplasty Outcomes. Our study elucidates trends and popular areas of research in the field of knee surgery, and provides researchers with an overview of areas to focus, where there is scope for high-impact original research.

    Bibliometric analysis and evaluation of the journal Medicina Oral Patología Oral y Cirugía Bucal (2008-2018).
    P Valderrama, Á Valderrama, P Baca.
       BACKGROUND: In 2008 the journal Medicina Oral Patología Oral y Cirugía Bucal was included in Journal Citation Reports. To appraise its evolution and current status, this study carried out a bibliometric analysis and evaluation of the journal for the period 2008-2018.
    MATERIAL AND METHODS: From the Web of Science, Journal Citation Reports we obtained the indicators Journal Impact Factor (JIF), 5-year JIF, JIF without self-cites, Eigenfactor score and Article Influence score (2010-2017); and from the Core Collection database the following variables: number and article types, institutions and countries of origin of the authors (2008-2018), and the variable cited and citing journal data in 2017. Twelve articles/year (n=132) were randomly selected to gather: the time between submittal and acceptance of an article, number of authors/article, representation of each section, gender of first author, and funding.
    RESULTS: The journal occupied the third quartile of the JCR from 2010 to 2017, when it moved up to the second quartile. From 2008 to 2018 it published a total of 1,518 documents, 90% articles and 9.5% reviews. Sixty countries were represented, 48.68% of the documents coming from Spain, and overall 1,293 institutions were involved. Between submittal and acceptance of articles, the average time was 134.42 days, without differences between years. The mean of authors/article was 5.15, increasing over time. The sections most represented were Oral Medicine and Pathology, and Oral Surgery. There were no differences regarding the gender of the first author, and in general the authors did not provide information about funding received.
    CONCLUSIONS: The bibliometric results indicate a steadily improving position of this journal, along with a tendency to reduce self-citation. The time between reception of an article and its acceptance was very stable, the number of authors per article showed an increase, and there was a nearly equal representation of males and females as the first author.

    [Bibliometric analysis of female authorship in original articles in the journal ATENCIÓN PRIMARIA].
    Maria Giner-Soriano, Olaya López-Pereiro, Edurne Zabaleta-Del-Olmo, Mariona Pons-Vigués, Rosa Morros, Ainhoa Gómez-Lumbreras.
       OBJECTIVES: To determine the percentage of female authors in original articles published during 2periods, in the journal of Atención Primaria (Primary Care), and to examine the differences between the categories of authorship (first, last author, and co-author) between both periods.
    DESIGN: Cross-sectional study.
    SETTING: Feminine scientific production published during the periods 2007-2008 and 2017-2018.
    PARTICIPANTS: The study was focused on original articles.
    MAIN MEASUREMENTS: The following variables were collected in an ad hoc form: gender based on the name of the author, total number of women and men appearing as authors, and order of authorship. Absolute and relative authorship frequencies were calculated, and the χ2 test was used to examine the evolution of the percentages by type of authorship and gender.
    RESULTS: A total of 108 articles were analysed in 2007-2008, and 100 in 2017-2018. No statistically significant differences were observed between the mean numbers of women authors within and between periods. In 2007-2008 a total of 548 female authors were identified and 540 in 2017-2018, the percentage of female authors was 48.7% and 54.4%, respectively. Only an increase in the percentage of first authors was observed between periods.
    CONCLUSIONS: Practically one out of every 2authors of original articles published in the journal Atención Primaria was female. There was also a significant increase in the percentage of female first authors between the 2periods. Nevertheless, and despite the greater number of health workers, the number of latest female authors remain unchanged, which points to the persistence of female under-representation.

    A bibliometric study of research pertaining to the oldest-old (age eighty-five and older).
    Brady Daniel Lund, Ting Wang.
       Objective: This bibliometric study investigated literature pertaining to a quickly growing population worldwide: the oldest-old, individuals age eighty-five and older. The current state of research was surveyed, based on top authors, publishers, authorship networks, themes in publication titles and abstracts, and highly cited publications.
    Methods: Bibliographic data was abstracted from the Web of Science database. Microsoft Excel was used for data analyses related to top author, publishers, and terms. VosViewer bibliographic visualization software was used to identify authorship networks.
    Results: Publications pertaining to the oldest-old have increased dramatically over the past three decades. The majority of these publications are related to medical or genetics topics. Citations for these publications remain relatively low but may be expected to grow in coming years, based on the publication behavior about and increasing prominence of this population. Claudio Franceschi and the Journal of the American Geriatrics Society were found to be the author and journal with the most publications pertaining to the oldest-old, respectively.
    Conclusions: The oldest-old is a population of rapidly growing significance. Researchers in library and information science, gerontology, and beyond can benefit themselves and those they serve by participating in research and specialized services to marginalized populations like the oldest-old. This bibliometric study hopefully serves as a launch-point for further inquiry and research in the years to come.
