    Merkel Cell Carcinoma: A Bibliometric Analysis of the Top 100 Cited Publications.
    Kristen Russomanno, Rahul Raiker, Haig Pakhchanian, Min Deng.
      BACKGROUND: Bibliometric studies provide a quantitative statistical analysis of the published literature within a field of interest and allow for easy identification of the major contributing authors, funding sources, and publication trends within the field. To date, no bibliometric studies have been performed pertaining to Merkel cell carcinoma (MCC).OBJECTIVE: To identify the 100 most frequently cited articles in MCC through a bibliometric analysis of the literature.
    METHODS: Web of science was queried to determine the 100 most frequently cited MCC publications published between the years 1970 and 2019. Articles were listed by title, authors and their affiliated institutions, journal title and type, year of publication, country of origin, funding sources, and citation frequency.
    RESULTS: Among the 100 most frequently cited MCC publications, articles were cited between 67 and 589 times with a mean of 136.3 times. Articles were cited between 2.0 and 98.2 times per year since publication with a mean of 11.3 times per year. 67% of the articles were published in oncology journals; 33% and 10% of the articles in dermatology and surgery journals, respectively. The most represented journal was Cancer (12%). Paul Nghiem was the most frequently identified author (18%). 36% of the top 100 articles were published out of the University of Washington. The most frequent funding agency was the National Institutes of Health (77%).
    CONCLUSION: Through this bibliometric analysis, researchers can easily identify key publications pertaining to MCC, which may in turn enhance their approach to understanding and practicing evidence-based medicine regarding MCC.

    Dave L Dixon, Diana M Sobieraj, Roy E Brown, Rachel A Koenig, Madeleine Wagner, William L Baker.
      Objective. To perform a bibliometric analysis of pharmacy practice department chairs at US schools and colleges of pharmacy to determine factors associated with their level of scholarly productivity.Methods. Scopus was searched for all publications by pharmacy practice chairs from all pharmacy schools through August 11, 2020. Publication metrics (total number of publications and citations and the Hirsch-index (h-index), and year of first publication), as well as characteristics of the individual chair and institution were collected. Characteristics were compared across groups. A generalized linear model was used to determine the correlation between the total number of publications and h-index to school ranking by US News & World Report (USNWR).Results. One hundred forty-one pharmacy practice chairs were identified. The majority were male and at the rank of professor, with a similar proportion from public and private institutions. The median total number of publications and citations was 19 and 247, respectively, with a median h-index of eight. Compared with female chairs, male chairs had a higher median total of publications and citations and a higher h-index. Chairs at public institutions had a higher median total of publications and citations and a higher publication rate, h-index, and m quotient. The USNWR ranking for the school was significantly correlated with total publications and the h-index.Conclusion. Pharmacy practice chairs vary significantly in their scholarship productivity, although those at institutions with a larger emphasis on research were more prolific. Observed differences in the publication metrics of male and female chairs warrants further study to determine possible explanations for this finding and its potential impact.

    Radiomics in Oncology: A 10-Year Bibliometric Analysis.
    Haoran Ding, Chenzhou Wu, Nailin Liao, Qi Zhan, Weize Sun, Yingzhao Huang, Zhou Jiang, Yi Li.
      Objectives: To date, radiomics has been applied in oncology for over a decade and has shown great progress. We used a bibliometric analysis to analyze the publications of radiomics in oncology to clearly illustrate the current situation and future trends and encourage more researchers to participate in radiomics research in oncology.Methods: Publications for radiomics in oncology were downloaded from the Web of Science Core Collection (WoSCC). WoSCC data were collected, and CiteSpace was used for a bibliometric analysis of countries, institutions, journals, authors, keywords, and references pertaining to this field. The state of research and areas of focus were analyzed through burst detection.
    Results: A total of 7,199 pieces of literature concerning radiomics in oncology were analyzed on CiteSpace. The number of publications has undergone rapid growth and continues to increase. The USA and Chinese Academy of Sciences are found to be the most prolific country and institution, respectively. In terms of journals and co-cited journals, Scientific Reports is ranked highest with respect to the number of publications, and Radiology is ranked highest among co-cited journals. Moreover, Jie Tian has published the most publications, and Phillipe Lambin is the most cited author. A paper published by Gillies et al. presents the highest citation counts. Artificial intelligence (AI), segmentation methods, and the use of radiomics for classification and diagnosis in oncology are major areas of focus in this field. Test-retest statistics, including reproducibility and statistical methods of radiomics research, the relation between genomics and radiomics, and applications of radiomics to sarcoma and intensity-modulated radiotherapy, are frontier areas of this field.
    Conclusion: To our knowledge, this is the first study to provide an overview of the literature related to radiomics in oncology and may inspire researchers from multiple disciplines to engage in radiomics-related research.

    Gustavo A Viani, Andre G Gouveia, Alexandre A Jacinto, Fabio Y Moraes.
      OBJECTIVES: To provide an overview of the achievements and future research with stereotactic body radiotherapy (SBRT) in prostate cancer.METHODS: SBRT publications for prostate cancer were retrieved from the Web of Science and Dimension database. Bibliometric analyses were performed using VOSviewer and Prism graph. Analysis of variance test was used to compare the publication, citation, and the mean citation between specialty journals. Network maps were produced to identify authors' and countries' collaboration clusters.
    RESULTS: Between 2006 and 2020, 574 publications fulfilling the inclusion criteria were identified, and a significant growth trend in publication (P<0.0001) and citation (P=0.001) number was recognized over the period. The United States was the most productive country with 253 (44.2%) articles. The RED Journal had the highest number of publications (14%) and citations (19%). Urology journals published (P=0.01) and cited significantly less than radiation oncology journals (P=0.01). All open access and non-open access number of publications increased over time, with a significant difference between non-open access and open access journals (P<0.0001). Two author clusters were identified, in the United States with the collaboration of Canadian and British authors, and in Italy with the participation of European authors.
    CONCLUSION: The number of publications and citations on SBRT for prostate cancer has grown linearly in the last decades. The United States is the leading country in this research field, and the use of SBRT in oligometastatic disease, reirradiation, and salvage seems to be hot topics in this research field.

      The history of academic research on ependymoma is expansive. This review summarizes its history with a bibliometric analysis of the 100 most cited articles on ependymoma. In March 2020, we queried the Web of Science database to identify the most cited articles on ependymoma using the terms "ependymoma" or "ependymal tumors," yielding 3145 publications. Results were arranged by the number of times each article was cited in descending order. The top 100 articles spanned across nearly a century; the oldest article was published in 1924, while the most recent was in 2017. These articles were published in 35 unique journals, including a mix of basic science and clinical journals. The three institutions with the most papers in the top 100 were St. Jude Children's Research Hospital (16%), the University of Texas MD Anderson Cancer Center (6%), and the German Cancer Research Center (5%). We analyzed the publications that may be considered the most influential in the understanding and treatment management of ependymoma. Studies focused on the molecular classification of ependymomas were well-represented among the most cited articles, reflecting the field's current area of focus and its future directions. Additionally, this article also offers a reference for further studies in the ependymoma field.

    Sun Huh.
      BACKGROUND/AIMS: The present study investigated the relevance and network of institutions, keywords, and authors' countries of the articles in Clinical Endoscopy published from 2015 to May 2021 based on the Web of Science Core Collection.METHODS: The Web of Science Core Collection was searched with the term Clinical Endoscopy as the publication title on July 12, 2021. All 776 citations published from 2015 to May 2021 and 2,964 articles citing those 776 articles were analyzed using Biblioshiny.
    RESULTS: The corresponding authors were from 73 countries. Document coupling showed that the colorectal cancer-colonoscopyrandomized controlled trial cluster had the most significant impact and highest centrality. There were 442 articles with corresponding authors from Korea (57.0%). The number of collaborative works by Korean authors with the authors of other countries was 33 (7.5%). The articles were cited 2,964 times by corresponding authors from 37 countries.
    CONCLUSION: The above results show that Clinical Endoscopy has published several studies on gastrointestinal endoscopy. A large proportion of citations (84.7 %) were from outside Korea, indicating that the journal content is useful for global physicians. Collaborative work between authors from Korea and other countries should be encouraged to promote the journal.

    Nathan Efron, Lyndon W Jones, Phillip B Morgan, Jason J Nichols.
      PURPOSE: Publication metrics are derived for the fields of silicone hydrogel (SH) and daily disposable (DD) contact lenses.METHODS: A search of the Scopus database for papers in the fields of SH and DD contact lenses found 979 SH and 291 DD papers. Subject-specific h-indices for SH lenses (hSH-index) and DD lenses (hDD-index) were derived, in relation to five categories - authors, institutions, countries and journals - to serve as measures of impact. A short list of the most impactful entities was generated for each of the above five categories in the SH and DD fields.
    RESULTS: A paper entitled "Soft contact lens polymers: An evolution" by Nicholson and Vogt was the most highly cited article (495 citations) in both SH and DD fields. The most impactful entities for the SH and DD fields were: authors - Lyndon Jones (hSH = 33) and Philip Morgan (hDD = 15); institutions - the University of Waterloo (hSH = 37) and the University of New South Wales (hDD = 15); countries - the United States (hSH = 45) and the United Kingdom (hDD = 24); and journals - Optometry and Vision Science (hSH = 33) and Contact Lens and Anterior Eye (hDD = 17). Overall, the SH field (hSH = 64) is far more impactful than the DD field (hDD = 34).
    CONCLUSIONS: Impactful papers, authors, institutions, countries and journals in the SH and DD fields are identified. Optometry is revealed as the leading profession in relation to SH and DD publications.

    Social media for cardiovascular journals: State of the art review.
    Sherry-Ann Brown, Courtney Campbell, Michael Fradley, Annabelle Santos Volgman.
      In cardiovascular (CV) medicine, the use of social media (SoMe) has increased the dissemination of scientific knowledge, including the sharing of scientific journal articles. With the rapid growth of online methods for communicating scientific research, the critical question is whether online attention correlates with citations in academic journal articles. Traditionally, the performance of a scientific journal article has been determined by the number of times it has been cited. The impact factor and the number of citations in peer-reviewed journals are widely accepted measures of scientific impact. Social media platforms such as Twitter (Twitter.com) enable the development of novel article- or journal-level metrics for assessing effect and influence. Indeed, "alternative metrics" for journal article impact have been proposed, with the most frequently used being the Altmetric Attention Score (AAS; Altmetric.com). The relationship between these new metrics and established indicators such as citations has not been thoroughly investigated. We summarize numerous studies investigating associations between social media posts about journal articles and journal article citations. We then describe our own journal's social media strategy in light of these findings.

    C Martinez-Perez, C Alvarez-Peregrina, C Villa-Collar, A Arance-Gil, M A Sánchez-Tena.
      BACKGROUND AND OBJECTIVE: The implantation of multifocal intraocular lens (IOL) has increased in recent years, allowing patients to achieve good quality vision at all distances, independence from use of glasses, and consequently, an increase in quality of life. The main purpose of this study was to analyse the links between publications and authors via citation networks, as well to as identify the different research areas and determine the most cited publications.MATERIAL AND METHODS: The publication search was performed through the Web of Science database, using the terms «Multifocal intraocular lens», «Bifocal intraocular lens», «Trifocal intraocular lens», «Diffractive intraocular lens», «Refractive intraocular lens», «Accommodative intraocular lens» and «Extended depth of focus intraocular lens», for a time interval from 1989 to August 2020. The software used to analyse the publications was the Citation Network Explorer.
    RESULTS: A total of 1293 publications were found, with 11,730 citations generated in the network, and 2019 had the highest number of publications of any year. The most cited publication was «European multicenter study of the AcrySof ReSTOR apodized diffractive intraocular lens» by Kohnen et al., published in 2006. Four groups about different research areas in this field were found using the Clustering functionality: visual quality, IOL designs, ocular aberrations, or defocus curves.
    CONCLUSIONS: The citation network offers an objective and comprehensive analysis of the main articles on the different designs and classes of multifocal IOL.

    Sarah A Jacobs, Kate Van Loveren, Dana Gottlieb, Martina Brave, Jesse Loman, Layne Weinman, Nancy Kwon.
      STUDY OBJECTIVE: The objective of this study was to describe the proportion of female authors on original research articles and editorials across 4 emergency medicine journals from 2013 to 2019. A secondary objective was to examine the gender composition of middle authors in relation to the genders of their respective first and last authors.METHODS: In this observational study, we selected 4 journals in emergency medicine using the Journal of Citation Reports and prior literature to analyze genders of all authors from research articles and editorials published from January 2013 to September 2019. Reviewers identified author genders through web searches with matching academic qualifications or used a gender identification application programming interface to identify likelihood of male or female identity. The primary outcome was the proportion of female authors in each position.
    RESULTS: Selected publications included 2,980 original research articles with 18,224 authors (median 6, interquartile range [IQR] 4 to 8) and 433 editorials with 986 authors (median 2, IQR 1 to 2). Women occupied 34.9%, 24.3%, and 36.5% of first, last, and middle author positions on original research articles and 23.8%, 20.5%, and 34.2% of first, last, and middle author positions among editorials, respectively. Publications with female first and last authors (n=340 articles) had a larger proportion of female middle authors (49%, 634/1,290) compared to publications with male first and last authors (n=1667 articles, female middle authors 33% [2,215/6,771]).
    CONCLUSION: Over the 7 years examined, female authorship in these emergency medicine journals increased. A more pronounced gender gap exists in editorial authorship compared to research articles. On publications where the first and last author were women, a higher proportion of middle authors were women.

      INTRODUCTION: COVID-19 pandemic public health emergency is one of the worse disease outbreaks in the history of infectious disease. The consequence has resulted in over 4 million deaths globally. Therefore, a more in-depth understanding of the dynamics of the disease, vaccine development, and safety has become crucial for the disease eradication.OBJECTIVE: The study adopted bibliometric analysis to identify the global contribution in COVID-19 and Vaccine Safety and analyzed the current status, development, and research hotspots to reference for future research directions.
    METHODS: Studies published between January 1, 2019 and July 11, 2021 were retrieved from the Scopus database. Data analysis and visualization were conducted using VOSviewer ver 1.6.6, Bibliometrix app. (Using R).
    RESULTS: A total of 1827 publications with 12.14 average citations per document were identified. These publications were published in 796 journals by 10,243 authors (with 5.61 authors per document) from 80 countries/regions. About 33.75% of the researches were from the developed countries. The USA, China, and India were top contributors for scientific research on COVID-19 and vaccine safety. The "Vaccine" is the most productive journal with 58 articles. Li Y, NA NA, and Liu X were the top three prolific authors. Furthermore, "Human," "Coronavirus disease 2019," and "Drug safety," were the most common frontier topics.
    CONCLUSIONS: Our analysis highlights the characteristics of the most influential articles on COVID-19 related to vaccine safety. The findings provided valuable insight into the scientific research progress in this domain and suggest scaling-up research and information dissemination on COVID-19 and vaccine safety.

    Saif Aldeen AlRyalat, Osama El Khatib, Ola Al-Qawasmi, Hadeel Alkasrawi, Raneem Al Zu'bi, Maram Abu-Halaweh, Yara Alkanash, Ibrahim Habash.
      Background: Data sharing is now a mandatory prerequisite for several major funders and journals, where researchers are obligated to deposit the data resulting from their studies in an openly accessible repository. Biomedical open data are now widely available in almost all disciplines, where researchers can freely access and reuse these data in new studies. We aim to assess the impact of open data in terms of publications generated using open data and citations received by these publications, where we will analyze publications that used the Biologic Specimen and Data Repository Information Coordinating Center (BioLINCC) as an example. Methods: As of July 2019, there was a total of 194 datasets stored in BioLINCC repository and accessable through their portal. We requested the full list of publications that used these datasets from BioLINCC, and we also performed a supplementary PubMed search for other publications. We used Web of Science (WoS) to analyze the characteristics of publications and the citations they received. Results: 1,086 published articles used data from BioLINCC repository, but only 987 (90.88%) articles were WoS indexed. The number of publications has steadily increased since 2002 and peaked in 2018 with a total number of 138 publications on that year. The 987 open data publications received a total of 34,181 citations up to 1 st October 2019. The average citation per item for the open data publications was 34.63. The total number of citations received by open data publications per year has increased from only 2 citations in 2002, peaking in 2018 with 2361 citations. Conclusion: The vast majority of studies that used BioLINCC open data were published in WoS indexed journals and are receiving an increasing number of citations.

    Need for Speed: Investigating Publication Times and Impact Factors of Plastic Surgery Journals.
    Sahil Chawla, Sandeep Shelly, Rachel Phord-Toy, Faisal Khosa.
      Background: Prolonged publishing time in scientific journals can be discouraging for researchers because earlier publication can mean a higher h-index and more academic opportunities. In this study, we evaluated the publication time for articles in plastic surgery journals compared with journals in surgery and medicine. We also assessed correlations between publication speed and journal impact factors (IFs).Methods: The overall indexes of all plastic surgery journals were compared with journals in the discipline of surgery and medicine. In addition, we evaluated original articles published in all plastic surgical journals and the highest-ranking journals from various surgical subspecialties listed in the 2018 Journal Citation Report, assessing the time intervals from submission to publication, submission to acceptance, and acceptance to publication. Correlation between time interval and journal IF were analyzed.
    Results: A total of 18 plastic surgery journals were compared with 210 surgical journals. Our study found that the IFs of journals significantly affect submission-to-acceptance times of the articles (P < 0.05, Wilcoxon test). The median submission-to-publication time for all plastic surgery and all surgical journals was 29.7 weeks (IQR, 12.1 and 35.8) and 22.1 days (IQR,18.8 and 36.8), respectively.
    Conclusions: There is a significant submission to publication time lag in plastic surgery journals when compared with other nonplastic-surgery journals. There was a positive correlation between submission-to publication time and IF for plastic surgery journals but a negative correlation for surgery journals (Spearman Correlation). In the last 14 years, plastic surgery journals have remained slow in publishing articles.

    Cory K Mayfield, Ioanna K Bolia, Hansel Ihn, Aryan Haratian, Laith K Hasan, George F Hatch, Frank A Petrigliano, Alexander E Weber.
      BACKGROUND: Institutional academic productivity remains an influential factor in an applicant's selection of fellowship training. This study aimed to determine the quality and quantity of research in the United States orthopaedic sports medicine fellowship programs and identify those with highest productivity.METHODS: The Arthroscopy Association of North America Fellowship Directory was used to evaluate 88 fellowships in the United States. Publication data and Hirschberg indices (h-index) were collected from the Scopus database. Subanalysis was performed based on the number of publications and mean h-index.
    RESULTS: Total number of publications per faculty member ranged from 0 to 866, with a median of 20. The median h-index per faculty member was 9. The number of fellows was correlated with a higher mean average h-index of faculty members (P = 0.05). The five programs with the highest number of publications included Hospital for Special Surgery, Rush University, University of Pittsburgh Medical Center, Mayo Clinic in Rochester, and Boston Children's Hospital.
    CONCLUSIONS: Most academic productivity in sports medicine is produced by a relatively small number of fellowship programs in the United States. Of interest, the number of fellows or faculty does not affect significantly the quality or quantity of research productivity at top institutions.

    Trend research of vitamin D receptor: Bibliometric analysis.
    Mohamed Abouzid, Anna K Główka, Marta Karaźniewicz-Łada.
      Studies on vitamin D receptor (VDR) and its association with multiple disorders are expanding. This bibliometric study aims to find and summarize VDR-related publications, and compare them across various countries, organizations, and journals to demonstrate trends in VDR research. VOSviewer and Excel 2019 were used to classify and summarize Web of Science articles from 1900 to mid-2021. Total records of 8762 articles were analyzed, and maps of co-citations bibliometric keywords co-occurrence were designed. In conclusion, relative research interest and published papers related to VDR were growing in the past 30 years. The United States of America dominates the research regarding VDR. The highest quality of VDR research was achieved by the University of California System, University of Wisconsin System, and Harvard University. J Steroid Biochem Mol Biol, PLoS One, and J Biol Chem are the leading three productive journals on VDR. Various aspects of vitamin D deficiency associated disorders and genetic studies regarding VDR, including single nucleotide polymorphism, gene variants, epigenome, long non-coding ribonucleic acid (lncRNA), and small nucleolar RNA host gene 6 are potentially the recent research hotspot in this field. Moreover, coronavirus disease, polycystic ovary syndrome, non-alcoholic fatty liver disease, gut microbiota, gestational diabetes, systemic sclerosis, and chemoresistance are the trending medical conditions associated with VDR.

    Mustafa Soytas, Yavuz Onur Danacioglu, Mustafa Yucel Boz, Rahim Horuz, Selami Albayrak.
      AIM: The aims of this research were to analyze the urological literature published during the COVID-19 pandemic and to guide future research.MATERIAL AND METHODS: Between 2019 and 2021, the Web of Science (WoS) All Databases collection was searched for publications related to COVID-19 and Urology. The keywords used during this search were coronavirus-19, COVID-19, SARS-CoV-2, novel coronavirus, 2019-nCoV, pandemic, and/or urology. The top 50 cited (T50) publications were also identified and summarized. Exported Microsoft Excel files, Visualization of Similarities viewer (VOSviewer) software, and descriptive assessment were used for bibliometric and statistical analyses of the publications.
    RESULTS: In total, 582 publications related to COVID-19 and urology were identified. In these publications, the most active author, journal, country, and organization were Francesco Porpiglia, European Urology, the United States of America (USA), and La Paz University Hospital, respectively. The most commonly used keywords were telemedicine-telehealth, SARS-CoV-2, coronavirus, pandemic, residency, testicle, semen, kidney transplantation, endourology, and surgery. The most worrying issues in the articles are the negative impact of COVID-19 on resident training and permanent damage to urological organs.
    CONCLUSIONS: We analyzed all the articles related to COVID-19 and urology published to date in the WoS All Databases collection. The most commonly published articles were based on clinical and outpatient practice, telemedicine, residency training, transplantation, and testicles. The long-term adverse effects of the pandemic on urology practice and especially urological organs will need to be assessed further in future research.

    Trends of High-Impact Studies in Pharmacology and Pharmacy: A Cross-Sectional Study.
    Lingmin Chen, Yi Yang, Jin Fan, Yonggang Zhang, Nian Li.
      Objective: To investigate the trends of high-impact studies in pharmacology and pharmacy research and to provide evidence for future research in the field of pharmacology and pharmacy. Methods: A cross-sectional study was performed to understand the current status of high-impact studies (top 1%) in pharmacology and pharmacy research via InCites tool based on Web of Science Core Collection. VOSViewer software was used to visualize the results. The outcomes included development trends, countries, subject areas, research institutes, collaborative networks, and subject terms. Results: We found 4,273 high-impact (top 1%) studies between 2011 and 2020 in the field of pharmacology and pharmacy. The number of studies increased from 366 in 2011 to 510 in 2020. These studies were mainly distributed in the following Web of Science subject categories: pharmacology and pharmacy (n = 4,188); neurosciences (n = 397); chemistry, multidisciplinary (n = 359); chemistry, medicinal (n = 314); microbiology (n = 301); biotechnology and applied microbiology (n = 280). These studies were cited in 646,855 studies from more than 100 Web of Science subject categories, and studies in pharmacology pharmacy accounted for the largest share of these citations. The top three countries that contributed the highest number of studies were the United States, United Kingdom, and China. The top three institutions that contributed the highest number of studies in the United States were the University of California System, the National Institutes of Health (NIH), and Harvard University. The top research collaborative circle was from universities in the United States. The top international collaborative circle was from universities from the United States, United Kingdom, Australia, and China. The subject-term analysis indicated that cancer was still the top disease, NF-κB was the top signaling pathway, and drug-delivery and nanoparticles were the top methods. Conclusion: The high-impact studies in pharmacology and pharmacy research have grown over time. The United States, the United Kingdom, and China are the top countries that contributed the high-impact studies. Cancer is still the greatest challenge in the field of disease treatment. It calls for more international collaboration in pharmacology and pharmacy research, which will help discover novel drugs.

    Bibliometric Analysis on Geriatric Nursing Research in Web of Science (1900-2020).
    Arezoo Ghamgosar, Maryam Zarghani, Leila Nemati-Anaraki.
      Objective: Aging is a growing public health concern for people, organizations, and governments. The current study was undertaken to provide insights into the global research output on geriatric nursing.Methods: A bibliometric study was implemented using the WoS database for the period from 1900 to 2020. Various tools and measures were used to analyze and visualized.
    Results: The search strategy found 4923 papers. The oldest paper was written by Beverly C. Andre in 1953. As team size increases, so does the number of citations. The USA was the active country and the highest number of coauthors. New York University was an active institution. Stig Karlsson was the most active author in Geriatric Nursing with 28 articles from Sweden, followed by Koen Milisen and Sandman, with 26 articles each from Sweden and Belgium. The most frequent words in this field were depression, malnutrition, education, Alzheimer's disease, and dementia. The latest research themes in this field were COVID-19, interprofessional locomotive syndrome, emergency nursing, and public health. The most influential papers were specified. Journal of the American Geriatrics Society was the most active journal.
    Conclusions: Geriatric nursing is a rooted field and has received special attention in the last decade. Policymakers, especially in developing countries, should pay attention to geriatric nursing as a specialty of nursing to solve aging issues they would face considering the increasing elderly population.

    Naming the Problem: Publishing Trends within in Urology on Race, Health Disparities and Structural Racism.
    Adrien N Bernstein, Ruchika Talwar, Cheyenne Williams, Andres Correa, Brandon Mahal.
      OBJECTIVES: To assess publishing trends regarding the contribution of societal systems on health disparities within the urology literature.METHODS: We performed a bibliometric analysis of the top 15 urology journals for titles and abstracts with the term race or ethnicity between 2000-2021. Articles were graded by the presence of (1) race, (2) disparities secondary to race, or (3) racial disparities secondary to structural biases. Frequencies were tabulated and logistic regression was used to determine odds of disparities publishing.
    RESULTS: Our query returned 934 articles for review. In 484 (52%) articles, race was mentioned as a demographic/covariate. 110 (12%) abstracts noted a racial health disparity and only 2 articles implicated racism. Rates of more direct language varied significantly by journal and year of publication. Discussion of disparities increased over time, ranging from 0% in 2002 to 25% in 2020 (p-trend <0.001). Logistic regression demonstrated an 11% annual increase in the likelihood of disparity publishing (OR=1.11, 95%CI=1.08-1.14; p<0.001).
    CONCLUSIONS: While it is widely acknowledged that race is a determinant of health, often "race" itself is ascribed the risk when societal inequities are largely at fault. Despite the frequent use of race as a key covariate within the urologic literature, health-disparities relating to structural racism are rarely explicitly named. In order to address the systemic biases that underpin these inequities, increased awareness through clear language in publishing is needed.

    Global Analysis of Research Trends on Kidney Function After Nephron-Sparing Surgery: A Bibliometric and Visualised Study.
    Faris Abushamma, Abdulkarim Barqawi, Samah W Al-Jabi, Maha Akkawi, Mosab Maree, Sa'ed H Zyoud.
      Background: Nephron-sparing surgery (NSS) for small renal masses (SRMs) is currently the standard of care to treat renal cell carcinoma (RCC). The concept of partial resection of RCC has mainly been developed to preserve kidney function. Therefore, we have performed this study to explore the research activity that has been undertaken since the early twenty-first century to investigate the advantages of NSS on preserving kidney function and preventing chronic kidney disease (CKD).Methods: Based on the Scopus database, this bibliometric study was used to reveal publication patterns in the kidney function and NSS research field. The data were analysed with VOSviewer version 1.6.16 software, which was used to create a network visualisation map that included research hotspots in this area.
    Results: A total of 449 scientific publications focused on renal function in NSS between 2001 and 2020. One hundred and seventy (38%) of the total published articles originated from the USA. Journal of Urology, European Urology, and Journal of Endourology were the top publications detailing research in this field. Half (50%) of the top 10 cited articles were published in the Journal of Urology, with an average citation of around 200 per article. The three most encountered research themes were comparative studies between partial and radical nephrectomy in terms of kidney function and development of CKD, the impact of type and duration of ischemia during resection on glomerular filtration rate (GFR) decline, and the effect of different surgical approaches on intermediate and long-term kidney function.
    Conclusion: NSS for SRMs and RCC and its impact on kidney function is a hot topic in the literature, and the amount of published data has consistently been rising since 2000. However, even though hundreds of documents have studied this topic from various perspectives, there is a compelling need to answer several questions such as the overall survival (OS) benefit of performing NSS in localised RCC and head-to-head comparison of robotic-assisted versus laparoscopic NSS in terms of warm ischemia time and long-term decline in GFR.

    Slowed canonical progress in large fields of science.
    Johan S G Chu, James A Evans.
      In many academic fields, the number of papers published each year has increased significantly over time. Policy measures aim to increase the quantity of scientists, research funding, and scientific output, which is measured by the number of papers produced. These quantitative metrics determine the career trajectories of scholars and evaluations of academic departments, institutions, and nations. Whether and how these increases in the numbers of scientists and papers translate into advances in knowledge is unclear, however. Here, we first lay out a theoretical argument for why too many papers published each year in a field can lead to stagnation rather than advance. The deluge of new papers may deprive reviewers and readers the cognitive slack required to fully recognize and understand novel ideas. Competition among many new ideas may prevent the gradual accumulation of focused attention on a promising new idea. Then, we show data supporting the predictions of this theory. When the number of papers published per year in a scientific field grows large, citations flow disproportionately to already well-cited papers; the list of most-cited papers ossifies; new papers are unlikely to ever become highly cited, and when they do, it is not through a gradual, cumulative process of attention gathering; and newly published papers become unlikely to disrupt existing work. These findings suggest that the progress of large scientific fields may be slowed, trapped in existing canon. Policy measures shifting how scientific work is produced, disseminated, consumed, and rewarded may be called for to push fields into new, more fertile areas of study.

    Knowledge landscape of starter cultures: A bibliometric and patentometric study.
    Rosmery Cruz-O'Byrne, Cristian Casallas-Useche, Nelson Piraneque-Gambasica, Sonia Aguirre-Forero.
      BACKGROUND: Starter cultures are essential in food industry biotechnology, consisting of microorganism preparations inoculated to produce safe fermented foods with desirable sensory characteristics.OBJECTIVE: This study aims to identify and analyze the growth and flow of knowledge about starter cultures by creating scientific and technological profiles using patentometric and bibliometric indicators.
    METHODS: A search for patents and scientific articles was conducted in December 2020 following a proposed 10-step methodology using the Scopus® and Patentinspiration databases. The search strategy was based on the keywords "starter culture" and "fermentation" considering publications up to 2020.
    RESULTS: A total of 3035 articles and 719 patents were published until 2020, presenting a more significant number in the last ten (10) years due to the development of biological sciences and molecular biology with enzymes and microorganisms. Italy leads the scientific production while China leads the technological. It was also possible to determine the most productive author and inventors, the most influential articles and inventions, and the main scientific journals and patent offices.
    CONCLUSION: Scientific and technological activities have an exponential behavior showing that the knowledge about starter cultures continues to grow, becoming a field of interest for optimizing industrial processes related to food fermentation, thus achieving diversification of products that can satisfy the demand for food in an increasingly competitive global market.

    A Systematic Review of Retractions in the Field of Cardiothoracic and Vascular Anesthesia.
    Lisa Q Rong, Katia Audisio, Mohamed Rahouma, Giovanni J Soletti, Gianmarco Cancelli, Mario Gaudino.
      OBJECTIVES: No systematic studies on retractions in cardiothoracic and vascular anesthesia exist. The aim of this analysis was to identify characteristics and trends of retractions in this field over the past three decades.DESIGN: A search of the Retraction Watch Database for retracted articles published between 1990 and 2020 in the field of cardiothoracic and vascular anesthesia was performed.
    SETTING: A bibliometric study.
    PARTICIPANTS: Five thousand three hundred forty-four retractions with the term "medicine" in the subject code were selected. Retractions of full-length English articles reporting findings in cardiothoracic and vascular anesthesia were included.
    INTERVENTIONS: None.
    MEASUREMENTS AND MAIN RESULTS: A total of 63 articles published in 31 journals from January 1990 to August 2020 were retracted. The majority were original articles (n = 60, 95.2%) and retracted for scientific misconduct (n = 50, 79.4%). The percentage of retractions due to misconduct increased from 2010, with a spike in 2011 (n = 26/50, 52.0%), and reached a plateau in 2014. The three most common reasons for retraction were misconduct by the author (n = 31, 49.2%), duplication (n = 12, 19.0%), and errors within the manuscript (n = 11, 17.5%). The median time from publication to retraction was 4.3 years (IQR: 1.7-9.4) and decreased significantly over time (p < 0.001). The median impact factor (IF) of the journals that published retracted articles was 3.5 (IQR 2.0-4.5) and decreased significantly over the study period (p < 0.001).
    CONCLUSION: Scientific misconduct represents the most common reason for retraction in cardiothoracic and vascular anesthesia. The median time to retraction and journal IF decreased significantly over time. While this is promising, future efforts should be made to screen for falsified data and standardize the processes after retraction to highlight problematic manuscripts.

    Relationship between internal medicine journals' activity on social networks and the citations they receive.
    M M Bustos-Claro, V Ávila, D G Fernández-Ávila, Ó Muñoz-Velandia, Á A García.
      BACKGROUND AND OBJECTIVES: Social networks are a means for disseminating scientific information. Alternative metrics assessing the impact of scientific publications on social networks have been created. Our study aims to assess the correlation between the activity of internal medicine journals on social networks and traditional metrics based on citations.METHODS: Internal medicine journals were identified in the SCImago-Scopus database and information on traditional impact metrics was extracted. In addition, alternative metrics of activity were determined for Facebook, Twitter, YouTube, and Instagram. The correlation was assessed through Spearman's correlation coefficient.
    RESULTS: Of 134 Internal Medicine journals, 17 had a presence on the social networks evaluated. The SJR index was higher in journals with a presence on social networks vs. those without (59 vs. 18, p < .0001). The overall correlation between the SJR index and the number of followers/year was very strong for Facebook (Spearman's correlation coefficient 0.95, p < .05) and strong for Twitter (Spearman's correlation coefficient 0.54 p < .05).
    CONCLUSIONS: Our study suggests that there is a very strong correlation between social network activity metrics (mainly Facebook and Twitter) compared to traditional metrics based on the number of citations of internal medicine journals.

    A Publication Rate Comparison of Oral Communications Presented at the 2010 and 2015 French General Practice Congresses and European General Practice Network Meetings.
    Maxime Pautrat, Melissa Tenot, Jean Pierre Lebeau.
      BACKGROUND AND OBJECTIVES: We sought to assess and compare the publication rates of research presented at two French general practice congresses (Collège National des Généralistes Enseignants (CNGE, National College of General Practice Teachers) and Congrès de la Médecine Générale de France (CMGF [French General Practice Congress]) and the European General Practice Research Network (EGPRN) meetings held in 2010 and 2015.METHODS: We included all oral presentations from the 2010 and 2015 CNGE, CMGF and EGPRN meetings. We searched subsequent publications up to December 2018. We collected study themes, study designs, author qualifications, and journals for all published presentations.
    RESULTS: Overall, we included 701 oral presentations; 33% of the 2010 presentations, and 30% of the 2015 presentations were subsequently published (P=.40). For both years, the overall publication rate was higher for presentations from the EGPRN meetings compared with the French meetings (55.6% vs 27.1%; P&lt;.05). Published articles mostly concerned clinical research and quantitative methods from academic authors. Seventeen percent of articles from the EGPRN meetings were published by BMC Family Practice and the European Journal of General Practice, whereas 32% of articles from the French meetings were published by Exercer, the French Journal of General Practice.
    CONCLUSIONS: More than half of the presentations at the 2010 and 2015 EGRPN meetings were published, whereas the publication rate from the French meetings remained under 30%. Further efforts are needed to increase the publication rate of general practice studies in peer-reviewed international journals.

    Gender-specific analysis of the authors and the editorial board of Naunyn-Schmiedeberg's Archives of Pharmacology from 2000 to 2020.
    Rebecca Zehetbauer, Florentin von Haugwitz, Roland Seifert.
      Motivated by the worldwide debate on gender equality, we analyzed the gender structure of the authors and the editorial board of Naunyn-Schmiedeberg's Archives of Pharmacology. We wrote an algorithm to assign authors' first names to a gender to determine the gender distribution of publications. We evaluated publications from German research institutes from 2000 to 2020. This resulted in a data set of 2929 authors. We could assign a first name to almost all authors. The percentage of female authors increased until 2008, but thereafter stagnated at around 30%. The position of senior author is far less often held by women (around 15%). Even though multiple political measures were implemented to increase the female participation, our analysis has shown no increase regardless. We also observed a strong decrease in German authorship (both male and female) since 2000. In the editorial board and for advisory editors, there has been a substantial increase in the proportion of women since 2016 as the result of appointments by the editor-in-chief. We discuss the strengths and limitations of our study in context with the literature and current developments in society and science and methodological pitfalls of studies in this field. More research is required to obtain a full picture of gender structure in science and to be able to properly interpret the data.

    Systematic review and meta-analyses of studies analysing instructions to authors from 1987 to 2017.
    Mario Malički, Ana Jerončić, IJsbrand Jan Aalbersberg, Lex Bouter, Gerben Ter Riet.
      To gain insight into changes of scholarly journals' recommendations, we conducted a systematic review of studies that analysed journals' Instructions to Authors (ItAs). We summarised results of 153 studies, and meta-analysed how often ItAs addressed: 1) authorship, 2) conflicts of interest, 3) data sharing, 4) ethics approval, 5) funding disclosure, and 6) International Committee of Medical Journal Editors' Uniform Requirements for Manuscripts. For each topic we found large between-study heterogeneity. Here, we show six factors that explained most of that heterogeneity: 1) time (addressing of topics generally increased over time), 2) country (large differences found between countries), 3) database indexation (large differences found between databases), 4) impact factor (topics were more often addressed in highest than in lowest impact factor journals), 5) discipline (topics were more often addressed in Health Sciences than in other disciplines), and 6) sub-discipline (topics were more often addressed in general than in sub-disciplinary journals).

    Yeshwant R Chillakuru, Eleanor F Gerhard, Timothy Shim, Samuel H Selesnick, Lawrence R Lustig, John H Krouse, Ehab Y Hanna, Timothy L Smith, Edward W Fisher, Joseph E Kerschner, Ashkan Monfared.
      OBJECTIVE: To understand the effect of the COVID-19 pandemic on the volume, quality, and impact of otolaryngology publications.METHODS: Fifteen of the top peer-reviewed otolaryngology journals were queried on PubMed for COVID and non-COVID related articles from April 1, 2020 - March 31, 2021 (pandemic period) and pre-COVID articles from the year prior. Information on total number of submissions and rate of acceptance were collected from seven top-ranked journals.
    RESULTS: Our PubMed query returned 759 COVID articles, 4885 non-COVID articles, and 4200 pre-COVID articles, corresponding to a 34% increase in ENT publications during the pandemic period. Meta-analysis/reviews and miscellaneous publication types made up a larger portion of COVID publications than that of non-COVID and pre-COVID publications. Compared to pre-COVID articles, citations per article 120 days after publication and Altmetric attention score were higher in both COVID articles (citations/article: 2.75 ± 0.45, p<0.001; Altmetric attention score: 2.05 ± 0.60, p=0.001) and non-COVID articles (citations/article: 0.03 ± 0.01, p=0.002; Altmetric attention score: 0.67 ± 0.28, p=0.016). COVID manuscripts were associated with a 1.65 times higher acceptance rate compared to non-COVID papers (p<0.001).
    CONCLUSIONS: COVID-19 was associated with an increase in volume, citations, and attention for both COVID and non-COVID articles compared to pre-COVID articles. However, COVID articles were associated with lower evidence levels than non-COVID and pre-COVID articles. This article is protected by copyright. All rights reserved.

    Portuguese Authorship in Published Clinical Trials: Differences in Industry and Investigator Initiated Trials.
    Maria Pinheiro Andrade, Daniela Matias, Joana Batuca, Nélia Gouveia, Hélder Mota-Filipe, Emília Carreira Monteiro, Catarina Madeira.
      INTRODUCTION: The aim of this study was to investigate the Portuguese authorship in publications resulting from trials initiated by the industry or investigators and run in Portugal.MATERIAL AND METHODS: Clinical trials with Portuguese institutions as sponsor or recruiting centers, and registered in four clinical trial registries, in the last 14 years, were assessed. Publications of completed trials, from both the initiative of the industry and investigatorswere screened and compared.
    RESULTS: The percentage of published trials initiated by industry and investigators was similar (28.0%). However, the percentage of completed investigator-initiated trials (43.6%) was lower when compared to industry trials (69.7%). There was a higher percentage of Portuguese authorship in published investigator-initiated trials when compared with industry-initiated trials (47.1% vs 8.5%, respectively). Moreover, industry-initiated trials with Portuguese authors were published in journals with lower journal impact factor when compared with those published without authorship of Portuguese investigators. Oncology was the therapeutic area with the highest number of clinical trial registrations and publications. However, in publications with Portuguese authors, industry Initiated trials mainly focused on neurology while investigator-initiated trials had a higher number of papers in the fields of gastroenterology and infection diseases. Published trials with Portuguese authorship, initiated by the industry or investigators, also targeted different populations and had different purposes. In both cases, no significant differences were observed in terms of the journal impact factor or in the alignment of the published randomized trials with the respective reporting guidelines.
    DISCUSSION: When compared with previous publications, this study showed an increasing trend in the number of clinical trials in Portugal, published within similar timeframes, after trial conclusion. Even though both industry and investigator trials are published within the standards for reporting trials, the low number of Portuguese authorships in industry publications might underline the need for invigorating these independent clinical trials in Portugal by capacitating and empowering national clinical research teams.
    CONCLUSION: This study confirmed that even though all registered trials had the involvement of Portuguese institutions as a recruiting center, not all the published trials had Portuguese investigators as authors, mainly those initiated by the industry.

    Gender disparity in dermatologic society leadership: A global perspective.
    Dalia Limor Karol, Laura Sheriff, Sabeena Jalal, Jeffrey Ding, Allison R Larson, Rachel Trister, Faisal Khosa.
      Background: In the last half-century, there has been increased representation of women in medicine. Despite this increase, there continues to be underrepresentation of women in medical leadership positions. The objective of this study was to investigate the phenomenon of gender disparity in the leadership of professional societies of dermatology worldwide.Methods: Online databases were used to extract the names of global dermatologic societies. Individual society websites were accessed to obtain information on executive members. Data not available on society websites were obtained through internet searches. Scopus was used to obtain H-indexes and other bibliometric outcomes.
    Results: Our data collection spanned 92 countries, with 1733 society leaders identified and information available for 1710. In North America, Europe, Asia, Australia, and the Middle East, women were in a minority in dermatology professional society leadership. In South America, Central America, and Africa, women were in a slight majority. Across all professional societies, the role of president was more frequently held by men (n = 95) as opposed to women (n = 75). Female leaders were less likely to hold concurrent academic positions as deans/chairpersons/directors (83.33%) than their male counterparts (92.06%). The median H-index of female leaders (9) was lower than that of men (14).
    Conclusion: Gender disparity exists in leadership positions in professional dermatology societies. Cultural/continental specific factors should be explored further. Enhancement of institutional support, mentorship, and sponsorship for female dermatologists should be encouraged.

    Scientific prizes and the extraordinary growth of scientific topics.
    Ching Jin, Yifang Ma, Brian Uzzi.
      Fast growing scientific topics have famously been key harbingers of the new frontiers of science, yet, large-scale analyses of their genesis and impact are rare. We investigated one possible factor connected with a topic's extraordinary growth: scientific prizes. Our longitudinal analysis of nearly all recognized prizes worldwide and over 11,000 scientific topics from 19 disciplines indicates that topics associated with a scientific prize experience extraordinary growth in productivity, impact, and new entrants. Relative to matched non-prizewinning topics, prizewinning topics produce 40% more papers and 33% more citations, retain 55% more scientists, and gain 37 and 47% more new entrants and star scientists, respectively, in the first five-to-ten years after the prize. Funding do not account for a prizewinning topic's growth. Rather, growth is positively related to the degree to which the prize is discipline-specific, conferred for recent research, or has prize money. These findings reveal new dynamics behind scientific innovation and investment.

    Alcohol, cardiovascular disease and industry funding: A co-authorship network analysis of systematic reviews.
    Su Golder, Jim McCambridge.
      BACKGROUND: Alcohol's effects on heart health is the site of a major scientific controversy. We conducted a co-authorship network analysis of systematic reviews on the impacts on alcohol on cardiovascular disease (CVD) in order to investigate patterns of co-authorship in the literature, with particular attention given to industry funding.METHODS: We used Epistemonikos to identify systematic reviews. Review characteristics, influential authors, co-authorship subnetworks, prior histories of alcohol industry funding, study outcomes and citations were investigated.
    RESULTS: 60 systematic reviews with 231 unique authors met our inclusion criteria. 14 systematic reviews were undertaken by authors with histories of alcohol industry funding, including 5 that were funded directly by the alcohol industry itself. All 14 such reviews identified a cardioprotective effect of alcohol. These formed distinct co-authorship subnetworks within the literature. Of reviews by authors with no prior histories of alcohol industry funding, the findings were mixed, with 54% (25/46) concluding there was evidence of health protective effects. These two groups of reviews differed in other respects. Those with industry funding were more likely to study broader outcomes such as 'cardiovascular disease' or 'coronary heart disease' as opposed to specific CVD issues such as hypertension or stroke (93% [13/14] versus 41% [19/46]) (chi-squared 12.4, p < 0.001) and have more included studies (mean of 29 versus 20). They were also more widely cited by others. Over time the proportions of systematic reviews on CVD and alcohol undertaken by authors with no prior histories of alcohol industry funding has increased.
    CONCLUSIONS: Systematic reviews undertaken by authors with histories of alcohol industry funding were more likely to study broader outcomes, and be cited more widely, and exclusively reported favorable conclusions.

    Assessment of skin of color and diversity and inclusion content of dermatologic published literature: An analysis and call to action.
    Britney N Wilson, Mary Sun, Alyssa Gwen Ashbaugh, Simran Ohri, Christopher Yeh, Dedee F Murrell, Jenny E Murase.
      Background: Previous reports have revealed inadequate resident education and textbook representation of dermatological conditions in patients with skin of color (SoC). This suggests that the literature and continuing medical education are important alternative dermatology educational resources to aid in diagnosing and treating patients of color.Objective: This study develops criteria to assess and examine the prevalence of SoC-related publications among top dermatology journals.
    Methods: We developed the first-ever prespecified criteria that allow for the assessment of diversity in the dermatologic literature. The archives of 52 dermatology journals from January 2018 to October 2020, selected based on Scopus ranking, were analyzed for journal characteristics and content regarding skin and hair of color, diversity and inclusion, and socioeconomic/health care disparities that affect underrepresented populations with SoC.
    Results: Our study reveals that the average percentage of overall publications relevant to SoC is quite low. The percent of SoC articles ranged from 2.04% to 16.8% with a mean of 16.3%. The top-performing dermatology journals in SoC were, not surprisingly, from countries with populations with SoC; however, the Journal of Cosmetic and Laser Therapy, Australasian Journal of Dermatology, and Journal of the American Academy of Dermatol Case Reports were among the top 10. Research and higher-impact journals were among the lowest in SoC rankings, including the Journal of Investigative Dermatology, Experimental Dermatology, and Journal of the American Academy of Dermatology, and had <5% of articles on SoC.
    Conclusion: We believe that the criteria we established could be used by journal editors to include at least 16.8% of SoC-relevant articles in each issue. Increasing SoC content in the dermatological literature, and particularly in high-impact journals, will serve as an invaluable educational resource and aid in promoting excellence in the care of patients with SoC.

    The landscape of the Characteristics, Citations, Scientific, Technological, and Altmetrics Impacts of Retracted Papers in Hematology.
    Sirous Panahi, Samira Soleimanpour.
      Retraction is a mechanism for eliminating and correcting serious problems in the scientific literature and increasing awareness among members of the scientific community about unreliable literature. The objectives of this study were to identify the characteristics and reasons for retraction, analyze citations, and describe the scientific, altmetrics, and technological impacts of hematology retracted papers. Retracted papers were searched using the hematology category of the Web of Science database. The search yielded 101 retracted papers in WoS. Statistics methods such as frequency, mean, interquartile range (IQR), and Pearson's Correlation were used for data analysis. The findings showed the retracted papers were published in 28 different hematology journals. The majority of retracted documents were in Article type (n=81). The mean time interval of the retracted papers from the first publication to retraction was 50.83 months. The largest number of retracted papers belonged to the United States (n= 46). The most frequently reported reason for retraction was misconduct (n= 55). The findings of this study provide a landscape into the characteristics and citations of retracted papers before and after retraction in addition to the scientific, technological, and altmetrics impacts of hematology retracted papers in the scientific community.

    15 Year Trends in Participation of Women in Presentation and Leadership Positions in the Southern Association for Vascular Surgery, 2006-2020.
    M Libby Weaver, Rebecca Sorber, Michol Cooper.
      OBJECTIVES: The implementation of integrated vascular surgery training programs was recently shown to be associated with an increase in women entering the field. However, whether this has precipitated a subsequent increase in the active participation of women in academic vascular societies remains unclear. We sought to examine the trends of academic inclusion of women vascular surgeons and surgical trainees over the past fifteen years at the Southern Association for Vascular Surgery (SAVS).METHODS: Scientific programs for annual meetings of the SAVS, and program matriculation statistics from the ACGME, were reviewed for the period 2006-2020. Yearly rates and three-year averages of conference and society participation and vascular surgery training program matriculation rates were calculated and compared with proportion testing. Spearman's correlation testing was used to compare trends, with ρ ≥0.600 defined as a strong correlation.
    RESULTS: Examining 3 year means, the average number of women authors per SAVS abstract increased from 0.78 to 1.42 over the course of the study period (p<0.001) and the overall rate of women authors steadily increased from 12.8% to 21.5% (p<0.001). While this remains less than the proportion of women matriculating into vascular surgery programs in 2019 (29.3%, p=0.007), the upward trend of women entering vascular surgery overall, and particularly vascular surgery fellowship, strongly correlates with the average number of women authors on abstracts at SAVS (ρ=0.709 and 0.737, respectively). The percentage of women presenting authors increased from 9.7% to 28.4% (p=0.004), but there was no increase in the percentage of women senior authors (10.1% to 9.6%, p=0.92). In the 15 year period, only one abstract out of 347 (0.3%) had full authorship by women versus 35.1% with full authorship by men (p< 0.001). Although the increase of women matriculating into vascular surgery programs over the study period did not correlate with the increase of women in senior leadership positions (ρ<0.600), there was an increase in the number of women in committee chair positions (0.0% to 25.9%, p=0.005) which correlated strongly with increasing society membership (ρ=0.716). Additionally, there was an increase in women holding executive council positions from 0% to 10.0% (p=0.08), although this was not statistically significant.
    CONCLUSION: Participation of women authoring and presenting papers at the SAVS has increased over the past 15 years at a rate that strongly correlates with the increasing rate of women entering vascular surgery training programs. It is important that society leadership opportunities continue to parallel this trend as we seek to further improve diversity in vascular surgery.

    Shared burden is always lighter - Peer-review performance in an ophthalmological journal 2010-2020.
    Tomas Bro, Björn Hammarfelt.
      PURPOSE: There are concerns in the academic publishing community that it is becoming more difficult to secure reviews for scientific manuscripts. This study examines trends in editorial and peer review processes in an ophthalmological journal over the last decade.METHODS: A retrospective analysis was performed of editorial data from the journal Acta Ophthalmologica containing all manuscript submissions between 2010 and 2020.
    RESULTS: The number of yearly submissions grew between 2010 and 2019 from 1014 to 1623, and in 2020, the number of submissions increased to 2449. In total, the number of submissions increased by 142% between 2010 and 2020. Similarly, the proportion of desk-rejected manuscripts increased from 48% to 67% during the period 2010-2020. The number of invitations needed to obtain one review showed an increase from 1.9 to 2.6 between 2010 and 2019, but remained stable between 2019 and 2020. However, the number of reviewers per reviewed manuscript, reviewed manuscripts per reviewer and time from invitation to completed review assignment remained almost constant between 2010 and 2020. Researchers based in North American were disproportionally often invited to review (18%) compared to their share of published articles (7%), and they also declined review invitation more frequently compared to scholars in other parts of the world.
    CONCLUSIONS: The study revealed an increase in submitted manuscripts to an ophthalmological journal over the last decade, with a further increase during the COVID-19 pandemic. The number of reviewer invitations needed to obtain one review grew during the study period but remained constant between 2019 and 2020, despite a vast increase in submitted manuscripts. Hence, the burden for unique reviewers did not increase. Instead, the proportion of desk-rejected manuscripts grew, and the reviewer pool expanded, which allowed the annual average number of reviews by individual reviewers to remain stable.

    Characterizing Research About Interprofessional Education Within Pharmacy.
    Amanda A Olsen, Carly P Lupton-Smith, Philip T Rodgers, Jacqueline E McLaughlin.
      Objective. To determine how interprofessional education (IPE) in pharmacy has been studied, namely which disciplines have engaged in IPE research initiatives, the research methodologies that have been used, and what journals have published in this area.Findings. In the 145 IPE studies included in the review, the authors represented 13 different disciplines (3.2±1.5 disciplines per study). Pharmacy authors most commonly published with co-authors from nursing, medicine, and health management and support and most frequently served as first author or last author. The IPE activities involved 4.0 student disciplines (SD = 1.9) and 211.8 students (SD = 280.1), and most commonly included nursing (n = 104, 71.7%), medicine (n = 102, 70.3%), and health management and support students (n = 50, 34.5%). Most studies did not include an author from each student discipline involved in the IPE (n = 88, 60.7%). Further, a majority of studies used nonrandomized groupings (n = 103, 71.0%) with quantitative data (n = 74, 51.0%) and most were published in an interprofessional journal (n = 65, 44.8%) or pharmacy-specific journal (n = 45, 31.0%).Summary. Pharmacists have increased their engagement in IPE research as demonstrated by the number of articles published and authorship order position. However, mismatches between student disciplines and author disciplines on published papers elucidate opportunities to foster collaborations that position students for success within a collaborative healthcare environment.

    Main challenges to international student mobility in the European arena.
    Cristina López-Duarte, Jane F Maley, Marta M Vidal-Suárez.
      This study analyses international student mobility (ISM) in Europe since the 1999 Bologna Declaration. International mobility of higher education students is both a driver and a consequence of the Bologna Process and emerges as a relevant issue in a wide range of research areas. This literature review develops a qualitative content analysis of the set of high-performance articles published between 2000 and 2018 and identified through a wide range of bibliometric tools: direct (first generation) citation counts; indirect or accumulated impact; early influence; adjusted impact with respect to year of publication, type of document, and discipline; and alternative metrics that measure interactions in the internet and social media. The content analysis focuses on the pending achievements and main challenges to ISM, among them: attracting non-European students to whole degree programs, the need for actual and further convergence in programs and systems to ensure real compatibility, the impact of HE ISM on the promotion of the European citizenship and consciousness, the sharp imbalance between credit and degree mobility, the need to strengthen the link between ISM and employability, the existing social selectivity in European ISM, the frequent social segregation problems faced by international students.

    50 years of radiotherapy research: evolution, trends and lessons for the future.
    Thomas Berger, David J Noble, Leila E A Shelley, Kirsten I Hopkins, Duncan B McLaren, Neil G Burnet, William H Nailon.
      Rapid and relentless technological advances in an ever-more globalized world have shaped the field of radiation oncology in which we practise today. These developments have drastically modified the habitus† of health professionals and researchers at an individual and organisational level. In this article we present an analysis of trends in radiation oncology research over the last half a century. To do so, the data from >350,000 scientific publications pertaining to a yearly search of the PubMed database with the keywords cancer radiotherapy was analysed. This analysis revealed that, over the years, radiotherapy research output has declined relative to alternative cancer therapies, representing 64% in 1970 it decreased to 31% in 2019. Also, the pace of research has significantly accelerated with, in the last 15 years, a doubling in the number of articles published by the 10% most productive researchers. Researchers are also facing stronger competition today with a proportion of first authors that will never get to publish as a last author increasing steadily from 58% in 1970 to 84% in 2000. Additionally, radiotherapy research output is extremely unequally distributed in the world, with Africa and South America contributing to ∼3% of radiotherapy articles in 2019 while representing 23% of the world's population. This disparity, reflecting economic situations and radiotherapy capabilities, has a knock-on effect for the provision of routine clinical treatment. Since research activity is inherent to delivery of high quality clinical care, this contributes to the global inequity of radiotherapy services. Learning from these trends is crucial for the future not only of radiation oncology research but also for effective and equitable cancer care.

    Research Topics and Trends in Interprofessional Education in Nursing: A Text Network Analysis.
    Kisook Kim, Ki-Seong Lee.
      To provide nurse-led interprofessional practices in a healthcare setting, carrying out effective research that identifies the trends and characteristics of interprofessional education is necessary. This study aimed to objectively ascertain trends in the field through text network analysis of different types of interprofessional education literature. Titles and thesis abstracts were examined for terms "interprofessional education" and "nursing" and were found in 3926 articles from 1970 to August 2018. Python and Gephi software were used to analyze the data and visualize the networks. Keyword ranking was based on the frequency, degree centrality, and betweenness centrality. The terms "interprofessional," "education," "student," "nursing," and "health" were ranked the highest. According to topic analysis, the methods, provided programs, and outcome measures differed according to the research field. These findings can help create nurse-led research and effective future directions for interprofessional education pathways and topic selection. This will emphasize the importance of expanding research on various education programs and accumulating evidence regarding the professional and interdisciplinary impact these programs have on undergraduate and graduate students.

    Female authorship of covid-19 research in manuscripts submitted to 11 biomedical journals: cross sectional study.
    Angèle Gayet-Ageron, Khaoula Ben Messaoud, Mark Richards, Sara Schroter.
      OBJECTIVE: To describe prominent authorship positions held by women and the overall percentage of women co-authoring manuscripts submitted during the covid-19 pandemic compared with the previous two years.DESIGN: Cross sectional study.
    SETTING: Nine specialist and two large general medical journals.
    POPULATION: Authors of research manuscripts submitted between 1 January 2018 and 31 May 2021.
    MAIN OUTCOME MEASURES: Primary outcome: first author's gender.
    SECONDARY OUTCOMES: last and corresponding authors' gender; number (percentage) of women on authorship byline in "pre-pandemic" period (1 January 2018 to 31 December 2019) and in "covid-19" and "non-covid-19" manuscripts during pandemic.
    RESULTS: A total of 63 259 manuscripts were included. The number of female first, last, and corresponding authors respectively were 1313 (37.1%), 996 (27.9%), and 1119 (31.1%) for covid-19 manuscripts (lowest values in Jan-May 2020: 230 (29.4%), 165 (21.1%), and 185 (22.9%)), compared with 8583 (44.9%), 6118 (31.2%), and 7273 (37.3%) for pandemic non-covid-19 manuscripts and 12 724 (46.0%), 8923 (31.4%), and 10 981 (38.9%) for pre-pandemic manuscripts. The adjusted odds ratio of having a female first author in covid-19 manuscripts was <1.00 in all groups (P<0.001) compared with pre-pandemic (lowest in Jan-May 2020: 0.55, 98.75% confidence interval 0.43 to 0.70). The adjusted odds ratio of having a woman as last or corresponding author was significantly lower for covid-19 manuscripts in all time periods (except for the two most recent periods for last author) compared with pre-pandemic (lowest values in Jan-May 2020: 0.74 (0.57 to 0.97) for last and 0.61 (0.49 to 0.77) for corresponding author). The odds ratios for pandemic non-covid-19 manuscripts were not significantly different compared with pre-pandemic manuscripts. The median percentage of female authors on the byline was lower for covid-19 manuscripts (28.6% in Jan-May 2020) compared with pre-pandemic (36.4%) and non-covid-19 pandemic manuscripts (33.3% in Jan-May 2020). Gender disparities in all prominent authorship positions and the proportion of women authors on the byline narrowed in the most recent period (Feb-May 2021) compared with the early pandemic period (Jan-May 2020) and were very similar to values observed for pre-pandemic manuscripts.
    CONCLUSIONS: Women have been underrepresented as co-authors and in prominent authorship positions in covid-19 research, and this gender disparity needs to be corrected by those involved in academic promotion and awarding of research grants. Women attained some prominent authorship positions equally or more frequently than before the pandemic on non-covid-19 related manuscripts submitted at some time points during the pandemic.

    Comparison of Publication of Pediatric Probiotic vs Antibiotic Trials Registered on ClinicalTrials.gov.
    Madison Riddell, Kaden Lam, Anna Funk, Nidhi Lodha, Diane L Lorenzetti, Stephen B Freedman.
      Importance: The published evidence in support of probiotic use is conflicting, which may be a result of selective publication of probiotic trials.Objectives: To compare the proportion of registered trials that evaluate pediatric probiotics vs those that evaluate antibiotics that are published and to identify study-related factors associated with publication status.
    Design, Setting, and Participants: This cross-sectional study evaluated eligible trials registered in ClinicalTrials.gov, an online clinical trials registry, from July 1, 2005, to June 30, 2016. Eligible studies included participants younger than 18 years, evaluated a probiotic or 1 of the 5 most commonly prescribed antibiotics in children and adolescents, and randomized study participants. All searches were updated and finalized as of September 9, 2020.
    Exposures: Probiotic or antibiotic.
    Main Outcomes and Measures: The primary outcome was study publication status. In addition, exposure status (probiotic vs antibiotic), trial result, and funding source were assessed for independent association with publication status. Whether study design elements, publication journal impact factor, and the interval from study completion to publication differed by exposure status were also evaluated.
    Results: A total of 401 unique trials (265 probiotic and 136 antibiotic) met eligibility criteria. A greater proportion of antibiotic compared with probiotic studies were published (83 [61.0%] vs 119 [44.9%]; difference, 16.1% [95% CI, 5.8%-25.9%]). After adjustment for funding source, blinding, and purpose, studies evaluating an antibiotic were more likely to be published (odds ratio, 2.1 [95% CI, 1.3-3.4]). No other covariates included in the model were independently associated with publication status. Antibiotic trials, compared with probiotic trials, were more likely to have a therapeutic purpose (114 [83.8%] vs 117 [44.2%]; difference, 39.6% [95% CI, 31.1%-48.3%]) and to be multicenter (46 [33.8%] vs 46 [17.4%]; difference, 16.5% [95% CI, 7.5%-25.7%]). The median impact factor of the journals in which the studies were published was higher for the antibiotic trials (7.2 [IQR, 2.8-20.5] vs 3.0 [IQR, 2.3-4.2]; P < .001). The median number of days to publication did not differ between the probiotic and antibiotic trials (683 [IQR, 441-1036] vs 801 [IQR, 550-1183]; P = .24).
    Conclusions and Relevance: The findings of this cross-sectional study suggest that probiotic studies are less likely to be published than antibiotic trials. No other study characteristics were associated with publication status. This finding raises concerns regarding the results of meta-analyses of probiotic trials.

    Open Access and Article Processing Charges in Cardiology and Cardiac Surgery Journals: a Cross-Sectional Analysis.
    Dominique Vervoort, Jessica G Y Luc, Michel Pompeu B O Sá, Eric W Etchill.
      INTRODUCTION: Open access (OA) publishing often requires article processing charges (APCs). While OA provides opportunities for broader readership, authors able to afford APCs are more commonly associated with well-funded, high-income country institutions, skewing knowledge dissemination. Here, we evaluate publishing models, OA practices, and APCs in cardiology and cardiac surgery.METHODS: The InCites Journal Citation Reports 2019 directory by Clarivate Analytics was searched for "Cardiac and Cardiovascular Systems" journals. Sister journals of included journals were identified. All journals were categorized as predominantly cardiology or cardiac surgery. Publishing models, APCs, and APC waivers were defined for all journals.
    RESULTS: One hundred sixty-one journals were identified (139 cardiology, 22 cardiac surgery). APCs ranged from $244 to $5,000 ($244-5,000 cardiology; $383-3,300 cardiac surgery), with mean $2,911±891 and median $3,000 (interquartile range [IQR]: $2,500-3,425) across 139 journals with non-zero available APCs ($2,970±890, median $3,000, IQR: $2,573-3,450, cardiology; $2,491±799, median $2,740, IQR: $2,300-3,000, cardiac surgery). Average APCs were $3,307±566 and median $3,250 (IQR: $3,000-3,500) for hybrid journals ($3,344±583, median $3,260, IQR: $3,000-3,690, cardiology; $2,983±221, median $2,975, IQR: $2,780-3,149, cardiac surgery) and $1,997±832 and median $2,100 (IQR: $1,404-2,538) for fully OA journals ($2,039±843, median $2,100, IQR: $1,419-2,604, cardiology; $1,788±805, median $2,000, IQR: $1,475-2,345, cardiac surgery). Waivers were available for 51 (86.4%) fully OA and 37 (37.4%) hybrid journals. Seventeen journals were fully OA without APCs, one journal did not yet release APCs, and four journals were subscription-only.
    CONCLUSION: OA publishing is common in cardiology and cardiac surgery with substantial APCs. Waivers remain limited, posing barriers for unfunded and lesser-funded researchers.

    A bibliometric analysis of Health Promotion International content regarding unions, unionization and collective agreements.
    Jessica Muller, Faisal A Mohamed, Mary Catherine Masciangelo, Morris Komakech, Toba Bryant, Anum Rafiq, Azeezah Jafry, Dennis Raphael.
      A recent article brought together the health benefits of unionization and working under collective agreements. It was noted how Canadian health promotion texts, reports and statements made no mention of unionization and working under collective agreements as promoting health. This was seen as a significant omission and reasons for this were considered. In this article this analysis is extended to consider how contributors to the flagship health promotion journal Health Promotion International (HPI) conceptualize unions, unionization and working under collective agreements as promoting health. Of 2443 articles published in HPI since its inception, 87 or 3.6% make mention of unions, unionization, collective agreements or collective bargaining, with most saying little about their promoting health. Instead, 20 make cursory references to unions or merely see them as providing support and engagement opportunities for individuals. Forty-five depict unions or union members as involved in a health promotion programme or activity carried out by the authors or by government agencies. Only 33 articles explicitly mention unions, unionization or collective agreements as potentially health promoting, representing 1.3% of total HPI content since 1986. We conclude that the health promoting possibilities of unionization and working under collective agreements is a neglected area amongst HPI contributors. Reasons for this are explored and an Organisation for Economic Cooperation and Development report on the importance of collective bargaining is drawn upon to identify areas for health promotion research and action.

    Clusters of science and health related Twitter users become more isolated during the COVID-19 pandemic.
    Francesco Durazzi, Martin Müller, Marcel Salathé, Daniel Remondini.
      COVID-19 represents the most severe global crisis to date whose public conversation can be studied in real time. To do so, we use a data set of over 350 million tweets and retweets posted by over 26 million English speaking Twitter users from January 13 to June 7, 2020. We characterize the retweet network to identify spontaneous clustering of users and the evolution of their interaction over time in relation to the pandemic's emergence. We identify several stable clusters (super-communities), and are able to link them to international groups mainly involved in science and health topics, national elites, and political actors. The science- and health-related super-community received disproportionate attention early on during the pandemic, and was leading the discussion at the time. However, as the pandemic unfolded, the attention shifted towards both national elites and political actors, paralleled by the introduction of country-specific containment measures and the growing politicization of the debate. Scientific super-community remained present in the discussion, but experienced less reach and became more isolated within the network. Overall, the emerging network communities are characterized by an increased self-amplification and polarization. This makes it generally harder for information from international health organizations or scientific authorities to directly reach a broad audience through Twitter for prolonged time. These results may have implications for information dissemination along the unfolding of long-term events like epidemic diseases on a world-wide scale.
