    Publications on the Association Between Cognitive Function and Pain from 2000 to 2018: A Bibliometric Analysis Using CiteSpace.
    Kangyong Zheng, Xueqiang Wang.
      BACKGROUND This study aimed to use CiteSpace software to conduct a bibliometric analysis of published studies on the association between pain and cognitive function from 2000 to 2018. The study also aimed to determine publication patterns and authorship and to identify recent trends for research in this field. MATERIAL AND METHODS Publications on the association between cognitive function and pain between 2000 and 2018 were identified from the Web of Science database. Bibliographic information, including authorship, country, citation frequency, changes in citation, and interactive visualization were generated using CiteSpace software. Co-citation, or frequency of two publications cited together by another publication, was also studied. RESULTS On 8th January 2019, 4,889 publications were identified. The United States (1132 publications) and the University of Washington (87 publications) were the most productive country and institution, respectively. The journal, Pain (182 publications) had the largest number of publications and was the most frequently cited journal (citation counts, 1569) with the highest centrality (0.62). Author A had the largest number of publications (21). Author B had the greatest co-citation count (223). Author C tied with Author D as the first co-cited author in terms of centrality (0.18). Author E in 2011 (co-citation count, 96) and Author F in 2008 (centrality: 0.11) had the highest co-citation counts and centrality, respectively. The keyword 'empathy' ranked first for research developments with the highest citation burst (10.045). CONCLUSIONS Bibliometric analysis of the association between pain and cognitive function might identify new directions for future research.

    A Bibliometric Analysis of Publications on Oxycodone from 1998 to 2017.
    Fan Lei, Jishi Ye, Juan Wang, Zhongyuan Xia.
       Background: Oxycodone is a widely used opioid analgesic, which is involved in cancer pain and non-cancer pain. This study is intended to understand the publication characteristics of oxycodone research field and assess the quality of pertinent articles from 1998 to 2017.
    Methods: Oxycodone-related publications from 1998 to 2017 were retrieved from the Web of Science (WOS) and PubMed database. These papers were coded across several categories, such as total number, journals, countries, institutions, authors and citations reports. And the analysis of co-occurrence keywords was handled by VOSviewer software.
    Results: According to search strategies, a total of 2659 articles on oxycodone were published in world from 1998 to 2017 in WOS. Among the top 10 most productive organizations, six of them were American institutes, two of them were pharmaceutical enterprises and the other three were Finnish, Australian and Canadian institutes, which is similar with the distribution by country/region. Drewes AM from Denmark published most articles and PAIN MEDICINE is the most productive journal in oxycodone area. Meanwhile, clinical studies occupy a dominant position during the past 20 years. The 10 most cited papers were listed. Among these articles, 8 of them are reviews and 2 of those are meta-analysis. And the last decade (2008-2017) displayed that the newest keywords focus on "double-blind", "randomized controlled trial" and "neuropathic pain".
    Conclusions: The findings provided a comprehensive overview of oxycodone research. In view of the adverse effects of oxycodone, high-quality oxycodone studies both in basic studies and clinical trials need to be completed.

    Scientific impact of multiple sclerosis and neuromyelitis optica spectrum disorder research from Southeast Asia: A bibliometric analysis.
    Adrian I Espiritu, Carl Froilan D Leochico, Karl Josef Niño J Separa, Roland Dominic G Jamora.
       BACKGROUND: Scientific productivity in the Southeast Asian (SEA) region in the field of multiple sclerosis and neuromyelitis optica spectrum disorder (MS/ NMOSD) was hypothesized to be low in magnitude. The aim of this study was to determine and compare MS/ NMOSD research outputs among the SEA countries in terms of established bibliometric indices. The association between these productivity indices and relevant country-specific socioeconomic factors was also determined.
    METHODS: A systematic review was conducted to include all relevant published MS/ NMOSD studies in the SEA indexed in MEDLINE, Embase, Scopus and CENTRAL from the inception of these databases to August 1, 2019. Quantity of research productivity was measured in terms of the total published documents. Quality of research impact was evaluated by assessing the study designs of the published reports, publications in journals with impact factor (IF) and PlumX Metrics (citations, usage, captures, mentions and social medias). Population size, gross domestic product (GDP) per capita, percentage (%) of GDP allocated to research and development (R&D), and the total number of neurologists reported in each country were obtained from reliable published data.
    RESULTS: Out of 3,547 articles identified, only 142 articles fulfilled the eligibility criteria; therefore, the total number of publications in the SEA region related to MS/ NMOSD was deemed low in quantity. Most studies were cross-sectional and case reports/ series; hence, most studies offered low level of evidence. Since the aggregate scores in citations, usage, captures, mentions, and social medias in PlumX Metrics and publications in journals with IF were low, the overall quality of the published articles was considered low. Thailand (57 articles), Malaysia (40) and Singapore (29) contributed to the majority of publications on the topic-. GDP per capita was statistically correlated with usage. Percent GDP for R&D was positively correlated with total publications, usage, captures and social mediaindices.
    CONCLUSION: In conclusion, the scientific impact of MS/ NMOSD in the SEA was considered low in quantity and quality. This study must encourage researchers in the SEA to produce greater volumes of high-quality publications in this particular field and motivate governments to increase % GDP for R&D for the benefit of patients suffering fromthese rare and disabling conditions.

    A Scientometric Review of Resource Recycling Industry.
    Minxi Wang, Ping Liu, Zhaoliang Gu, Hong Cheng, Xin Li.
      With rapid economic development and urbanization, a large number of primary resources are consumed and accumulate in society as recyclable resource, which causes great pressure on the environment. The development of the resource recycling industry (RRI) can reduce environmental impacts and achieve sustainable development and green growth. Scholars are paying more attention to the resource recycling industry (RRI), and the related literature continues to increase. There are over 7041 publications covering RRI in the Web of Science database from 1996 to 2018. This paper analyzes the time distribution characteristics of the literature and the status of the scientific research cooperation network using the visualization analysis software CiteSpace. The number of documents increased from 94 in 1996 to a peak of 963 in 2018. There is no relatively stable core author group. The number of papers published by "Chinese Acad Sci" ranks first among all research institutions. Document co-citation analysis and burst detection are adopted to assess the status and emerging trends in the RRI research domain. A publication by M.C. Monte on waste management is the most cited paper. Additionally, "green and sustainable and technology" and "science and technology-other topics" are the latest emerging subject categories in RRI research. Furthermore, "e-waste", "reverse logistics" and "lean manufacturing" are emerging research trends for RRI, and "carbon emissions", "policy", "demolition waste", "supply chain management" and "compressive strength" have become hot topics. These findings may provide inspiration for scholars to search for new research directions and ideas.

    Rheumatological publications from Malaysia: a bibliometric study.
    Cheong Lieng Teng, Wei Zhuen Chew, Esha Das Gupta, Swan Sim Yeap.
       OBJECTIVES: To assess the content, authorship and study design of rheumatological publications written by Malaysian authors or about rheumatological conditions in Malaysia.
    METHODS: The Malaysian Medical Repository (MyMedR), a web-based database of Malaysian health and medical publications, and Scopus were searched to retrieve rheumatological publications from Malaysia, for the period 1950 until 30 June 2019. The type and number of publications in each rheumatological subject area and the overall trend of publication numbers and citations were analysed.
    RESULTS: 547 publications were found for the time period studied. There was a 27-fold increase in the number of publications from the period up to 1980 compared to 2010-2019. The median number of citations per paper was 5, but unlike the number of publications, there was only a slight increase in the number of citations with time. 84.5% of the papers were cited at least once. The top 3 conditions generating the most publications were systemic lupus erythematosus, 36.7%, followed by rheumatoid arthritis, 17.0%, and osteoporosis, 13.9%.
    CONCLUSIONS: The number of rheumatological publications in Malaysia have increased over time, especially in the last decade. However, the average number of citations per publications remains low and the majority of publications are in journals with low impact factors. Thus, the quality of rheumatological publications from Malaysia can be further improved.Key Points• There have been only a limited number of bibliometric analysis of rheumatology publications from Asia.• In Malaysia, the number of rheumatology publications has increased over time.• However, there is still room for improvement in terms of the quality of the publications.

    Biomedical and health research geography in the Eastern Mediterranean Region.
    Ghazi O Tadmouri, Ahmed Mandil, Arash Rashidian.
       Background: Measuring scientific outputs allows for objective evaluation of established health research systems and ranking countries according to scientific achievements. To our knowledge, attempts for systematic mapping health research output in the Eastern Mediterranean Region (EMR) are limited.
    Aims: We aimed to conduct a detailed bibliometric analysis of EMR biomedical and health research productivity during the period 2004-2013, considering country of first author.
    Methods: We applied an improved PubMed search strategy to obtain precise data on EMR research productivity, limiting articles to reviews, original research and case reports. Data were normalized to global research output, represented by total articles indexed in PubMed per year from 2004-2013, according to population size of each country. Second order polynomial trend lines were calculated and comparing 5-year periods: 2004-2008 with 2009-2013.
    Results: Inspecting overall raw data, a clear increasing trend is observed. Regional share of global health related research ranged from 0.85-2.36% of total PubMed indexed publications during the study period. Five countries contributed to 80% of all published articles during study period; i.e., Islamic Republic of Iran (39%), Egypt (14%), Saudi Arabia (11%), Tunisia, and Pakistan (8% each). Overall, 2.35 articles are published per 100 000 population per year. While Kuwait maintained the highest per capita publication (followed by Tunisia, Lebanon, Qatar and Islamic Republic of Iran), Qatar, Islamic Republic of Iran and Saudi Arabia demonstrated the highest "per capita" population growth in publications. Three academic institutions accounted for over 10% of all publications that were led by an investigator from the Region. Collectively, most prolific 25 EMR institutions published 44% of all published biomedical and health research in the EMR.
    Conclusions: The overall global share of EMR health research publication is smaller than its global share of population or wealth. Biomedical and health research needs greater encouragement and supporting many EMR countries and/or institutions, especially those found to be least prolific in our analysis. The increase in academic publication on health has been more prominent in a few countries only. It is anticipated that the concentration of biomedical and health research in EMR academic institutions would help in translating knowledge into public health outcomes, if more suitable conditions are provided.

    Author gender differences in psychology citation impact 1996-2018.
    Mike Thelwall.
      Academic psychology in the USA is a gender success story in terms of overturning its early male dominance but there are still relatively few senior female psychology researchers. To assess whether there are gender differences in citation impact that might help to explain either of these trends, this study investigates psychology articles since 1996. Seven out of eight Scopus psychology categories had a majority of female first-authored journal articles by 2018. From regression analyses of first and last author gender and team size, female first authors associate with a slightly higher average citation impact, but extra authors have a 10 times stronger association with higher average citation impact. Last author gender has little association with citation impact. Female first authors are more likely to be in larger teams and if team size is attributed to the first author's work, then their apparent influence of female first authors on citation impact doubles. While gender differences in average citation impact are too small to account for gender-related trends in academic psychology, they warn that male-dominated citation-based ranking lists of psychologists do not reflect the state of psychology research today.

    Worldwide research output trends on drinking and driving from 1956 to 2015.
    Juan Carlos Valderrama-Zurián, David Melero-Fuentes, F Javier Álvarez, Francisco Herrera-Gómez.
      This study seeks to analyze worldwide research activity on drinking and driving of macro-actors (countries and research fields) and meso-actors (institutions, journals, articles, co-substance(s) studied) during the last 6 decades (between 1956 and 2015). Web of Science and Elsevier Scopus were searched using terms referred to drinking and driving, including terms related to vehicles and way spaces. Overlapping was excluded and absence of false positives was confirmed. Articles on alcohol with/without other psychoactive substances were assessed quantitatively (bibliometric measures). Well identified by All Science Journal Classification system (ASJC) (Elsevier Scopus), an increase in the number of articles through the 6 decades analyzed was observed, from 152 (1956-1965) to 2302 (2006-2015), which represent an average decadal growth rate (ADGR) of 72.21. Among 89 countries, United States of America published 37.62 % out of all the included articles. Nevertheless, institutions from Canada, European Union and Australia published 50 articles or more during 60 years. The publications were mostly welcomed by journals on substance abuse research, and an exponential increase in publications on combined use of alcohol and other driving-impairing substances was observed since the second half of the eighties. This is the first study that attempted an analysis of scientific production of macro- and meso-actors on a topic belonging to an intricate research area. Bibliometric analyses should be considered as an important tool for updating the evidence on the serious problem of driving under the influence (DUI). The awareness of policy makers and the other relevant actors involved in the control of DUI of alcohol and other substances is stressed.

    Progress and prospects of medical education research in Asian Countries.
    Sultan Ayoub Meo, Kamran Sattar, Chaudhary Habib Ullah, Sami Alnassar, Waseem Hajjar, Adnan Mahmood Usmani.
       Background and Objectives: Medical education has a profound impact on health care system. Progress in achieving medical education research goals varies over time and across countries. This study aimed to investigate the medical education research ambience in Asia during the period 1965-2015.
    Methods: We investigated the bibliometric indicators of 49 Asian states in medical education research from 1965-2015. The data about Asian countries, their per capita GDP, expenditure on R&D, universities and indexed scientific journals were collected. We recorded medical education related research documents published in Institute of Scientific Information (ISI) Web of Science, Thomson Reuters during the period 1965-2015.
    Results: Asian countries collectively published 12721799 research articles, among them 40628 (0.31%) publications were in medical education. China contributed total of 3351565 articles among which 5414 (0.16%) research articles were in medical education; India added 1328725 papers with 4563 (0.34%) in medical education; Japan produced 3080257 papers with 4199 (0.13%) in medical education; Israel 561531 with 3848 (0.68%) in medical education; and lastly, Georgia contributed a total of 296532 research articles with 2565 (0.86%) in medical education.
    Conclusions: In Asia, the top five countries in medical education research are China, Georgia, Israel, Japan and India. The countries at low ranking are Yemen, Palestine, Myanmar, Kazakhstan, Syria and Armenia. In Asian states, the overall performance in medical science research needs policies to enhance its impact globally. Medical universities should offer research programs for learning and understanding the challengeable issues in medical education research.

    An Analysis of Recent FDA Oncology Scientific Publications.
    Julie A Schneider, Andrew C Miklos, James Onken, Yutao Gong, Anna Maria Calcagno, Gideon M Blumenthal, Richard Aragon, Richard Pazdur.
      In addition to its primary regulatory role, the Office of Hematology and Oncology Products at the U.S. Food and Drug Administration (FDA) is engaged in many forms of scientific authorship. During the period of 2010 to 2018, FDA oncology staff contributed to 356 publications in the scientific literature. Here, we collaborated with analysts in the Office of Program Planning, Analysis, and Evaluation at the National Institute of General Medical Sciences, National Institutes of Health (NIH), to present a series of analyses aimed at quantifying the characteristics and potential impact of these contributions, as well as characterizing the areas of work addressed. We found that FDA oncology papers are enriched for high-impact publications and have about two times the number of citations as an average NIH-funded paper. Further impact of the publications was measured based on the presence of 65 publications that were cited by guidelines and 12 publications cited by publicly listed clinical trials. The results seen here are promising in determining the impact of FDA oncology publication work but prompt further investigation into longer-term impacts, such as the influence of this work on other regulatory activities at FDA. IMPLICATIONS FOR PRACTICE: This article describes the first comprehensive study of scientific publications produced by U.S. Food and Drug Administration (FDA) oncology staff. The analysis illustrates that staff are highly engaged in publishing in the scientific literature in addition to completing regulatory review work. Publications are generally in clinical medicine, consistent with the large number of medical oncologists working at the Office of Hematology and Oncology Products (OHOP). OHOP publications generally focus either on communicating important regulatory work (approval summaries) or highlighting regulatory science issues to encourage dialogue with the scientific community (commentaries, reviews, and expert working papers). The analysis also suggests that several FDA oncology publications may influence clinical guidelines, but further work is needed to evaluate impact.

    Bibliometric Study of the Comorbidity of Pain and Depression Research.
    Xue-Qiang Wang, Meng-Si Peng, Lin-Man Weng, Yi-Li Zheng, Zhi-Jie Zhang, Pei-Jie Chen.
       Background: Comorbid pain and depression occur with high prevalence in clinical observations, and published academic journals about them have been increasing in number over time. However, few studies used the bibliometric method to analyze the general aspects of scientific researches on the comorbidity of pain and depression. The aim of this study is to systematically provide global scientific research in the comorbidity of pain and depression from 1980 to 2018.
    Methods: The published papers were searched between 1980 and 2018 in Web of Science. Publications related to comorbid pain and depression research were included. The language was restricted to English, and no species limitations were specified.
    Results: A total of 2,519 papers met the inclusion criteria in our study. The results revealed that the publications had a significant growth over time in the comorbidity of pain and depression research (P < 0.001) by linear regression analyses. The United States had the largest number of publications and citations and the highest value of H-index. According to subject categories of Web of Science, research areas of the 2,519 papers mainly focused on clinical neurology (28.78%), neurosciences (22.9%), and psychiatry (22.23%). In accordance with types of pain, headache (19.09%) was the most popular topic in the included papers on comorbid pain and depression research.
    Conclusions: The findings provide useful information for pain and depression researchers to detect new areas related to collaborators, cooperative institutions, popular topics, and research frontiers.

    The changing face of academic general surgery in Canada: a cross-sectional cohort study
       Background: Little is known regarding the research and training expectations faced by modern general surgery graduates interested in pursuing academic surgical careers. In this study, we describe the changing face of the Canadian academic general surgeon by outlining the in-residency research productivity and postresidency clinical and academic training trends over time.
    Methods: Our cross-sectional cohort included Canadian academic general surgeons, defined as those with a university-affiliated appointment as assistant, associate or full professor. Academic surgeons were identified by the Royal College of Physicians and Surgeons of Canada online directory as well as directories of university and hospital websites. Data points included institution, faculty appointment and rank, graduation year, graduate education, fellowship training and research productivity.
    Results: Our cohort included 417 surgeons from 17 Canadian academic institutions. The majority of surgeons were male (72.9%), had completed at least 1 fellowship (72.9%) and had had some form of supplementary research training (51.8%). Surgeons in the cohort had practised a median of 17 (10–27) years. The mean number of total and first-author publications for the participants in this study has increased consistently each decade before the 1980s (p < 0.001). The proportion of academic surgeons completing graduate degrees has increased steadily every decade, reaching a peak of 61.5% for surgeons graduating in the 2010s.
    Conclusion: The Canadian academic surgeon is becoming increasingly productive in research during residency and is pursuing higher levels of graduate education and more fellowships than ever before. These changes probably correspond to an evolving employment and research funding landscape that places tremendous academic pressure on surgical trainees.

    The Development of Necrotizing Enterocolitis Publications: A Holistic Evolution of Global Literature with Bibliometric Analysis.
    Gül Doğan, Hülya İpek.
       INTRODUCTION:  Despite the fact that necrotizing enterocolitis (NEC) is one of the reasons for morbidity and mortality in the newborn intensive care units, the literature indicates no bibliometric studies that made a holistic evaluation of the publications on this issue. This study aims to make a holistic evaluation of NEC publications to reveal the latest developments and trend topics.
    MATERIALS AND METHODS:  Bibliometric analyses were performed by retrieving all the publications in Web of Science (WoS: Web of Science Core Collection database maintained by Clarivate Analytics) database between 1980 and 2018 using the "necrotizing enterocolitis" keyword. The correlations between economic productivity, humanity index, and performances of the countries on the topic of NEC were investigated with Spearman's correlation coefficient.
    RESULTS:  A review of the related literature indicated 2,968 publications on NEC between 1980 and 2018. Of these publications, 1,690 (56.9%) were indexed in the article document category in WoS. There was an important increasing trend in the number of publications after 2006. Results of the present study showed that the Journal of Pediatric Surgery and Journal of Pediatrics were the top effective journal that contributed to the literature in terms of publication productivity. The top productive country that produced most publications about NEC was the United States (863, 51.1%).
    CONCLUSION:  Research on NEC is conducted in a limited number of countries. There seem to be more research opportunities in the developed countries because survival rates of premature babies having a disease like NEC are lower in the undeveloped countries, and survival rates are higher in developed countries due to appropriate intensive care conditions. Therefore, undeveloped countries should be supported in terms of NEC and provided with funds.

    Gender Disparities in Awards to Neuroscience Researchers.
    David E Melnikoff, Virginia V Valian.
      Women in academia receive fewer prestigious awards than their male counterparts. This gender gap may emerge purely from structural factors (e.g., gender differences in time spent in academia, institutional prestige, and academic performance), or from a combination of structural and psychological factors (e.g., gender schemas). To test these competing predictions, we assessed the independent contribution of year of degree, institutional prestige (a composite of prestige of PhD school and current affiliation), academic performance (total publications, total cites, and h-index), and gender to the prestige of awards earned by male (N = 298) and female (N = 134) academic neuroscientists. Award prestige was determined by an independent set of neuroscientists. Men earned more prestigious awards than women after controlling for institutional prestige, year of degree, and total publications. But after controlling for total citations or h-index, no gender difference appeared. Mediation analyses revealed that the gender disparity in awards was mediated by a gender difference in total cites and h-index. There was a reciprocal effect as well, in that the gender disparity in total cites and h-index was partially mediated by awards. These results point to an indirect path by which psychological factors may create gender disparities in academic awards: gender schemas may lead to women's papers receiving fewer citations than men's papers, resulting in more prestigious awards for men than for women. Additionally, our results suggest that gender disparities in awards and citations may reinforce each other. Practical implications for promoting gender equality in academic awards are discussed.

    Orthopaedic research in low-income countries: A bibliometric analysis of the current literature.
    Simon Matthew Graham, Ciaran Brennan, Maritz Laubscher, Sithombo Maqungo, David G Lalloo, Daniel C Perry, Nyengo Mkandawire, William J Harrison.
       BACKGROUND: To perform a bibliometric analysis and quantify the amount of orthopaedic and trauma literature published from low-income countries (LICs).
    METHODS AND METHODS: The Web of Science database was utilised to identify all indexed orthopaedic journals. All articles published in the 76 orthopaedics journals over the last 10 years were reviewed, to determine their geographic origin.
    RESULTS: A total of 131 454 articles were published across 76 orthopaedic journals over the last 10 years. Of these, 132 (0.1%) were published from LICs and 3515 (2.7%) were published from lower middle-income countries (LMICs); 85.7% (n = 112 716) of published orthopaedic research was undertaken in a high-income setting. The majority of the studies (n = 90, 74.4%) presented level IV evidence. Only 7.4% (n = 9) were high-quality evidence (level I or II). Additionally, the majority of research (74 articles, 56%) was published in partnership with high-income countries (HICs).
    CONCLUSIONS: There is a stark mismatch between the publication of scientific reports on orthopaedic research and the geographical areas of greatest clinical need. We believe there is an urgent need for orthopaedic research to be carried out in low-income settings to guide treatment and improve outcomes, rather than assuming that evidence from high-income settings will translate into this environment.
    LEVEL OF EVIDENCE: IV.

    Employing the Payback Framework to Assess Implementation Science Research Utilization: Lessons From the USAID's PEPFAR HIV/AIDS Implementation Science Awards.
    Delivette Castor, Allison L Kimmel, Allison McFall, Nancy Padian, Aisha Yansaneh, Sarah Wiant, Sarah Sandison, Charles Holmes, Rachel Lucas, David Stanton, Eric Goosby, Benny Kottiri.
       BACKGROUND: Stakeholders question whether implementation science (IS) is successful in conducting rigorous science that expedites the inclusion of health innovations into policies and accelerates the pace and scale of health service delivery into clinical and public health practice. Using the Payback Framework (PF) for research utilization (RU), we assessed the impact of USAID's IS investment on a subset of studies examining HIV prevention, care, and treatment.
    SETTING: Selected USAID-funded IS awards implemented between 2012 and 2017 in 9 sub-Saharan African countries.
    METHODS: A modified version of a RU framework, the PF, was applied to 10 USAID-funded IS awards. A semistructured, self-administered/interviewer-administered questionnaire representing operational items for the 5 categories of the modified PF was used to describe the type and to quantify the level of payback achieved. The raw score was tallied within and across the 5 PF categories, and the percentage of "payback" achieved by category was tabulated. Distribution of payback scores was summarized by tertiles.
    RESULTS: Knowledge production had the highest level of payback (75%), followed by benefits to future research (70%), benefits to policy (45%), benefits to health and the health system (18%), and broader economic benefits (5%).
    CONCLUSIONS: All awards achieved some level of knowledge production and benefits to future research, but translation to policy and programs was low and variable. We propose the use of policy, health system, and economic monitoring indicators of RU throughout the research process to increase IS studies' impact on health practice, programs, and policy.

    Trends in Leadership at Spine Surgery Fellowships.
    Chester J Donnally, Nicholas C Schiller, Alexander J Butler, Andrew J Sama, Kevin J Bondar, Vadim Goz, Kartik Shenoy, Alexander R Vaccaro, Alan S Hilibrand.
       STUDY DESIGN: Cross-sectional study.
    OBJECTIVE: To illustrate demographic trends among spine fellowship leaders (FLs).
    SUMMARY OF BACKGROUND DATA: No previous study in the orthopaedic literature has analyzed the demographic characteristics or past surgical training of FL in an orthopaedic sub-specialty. We attempt to illustrate demographic trends among spine fellowship leadership including fellowship directors (FDs) and co-fellowship directors (co-FDs). We also highlight the institutions that have trained these leaders at various levels.
    METHODS: Our search for FDs was constructed from the 2018-2019 North American Spine Surgery (NASS) Fellowship Directory. Datapoints gathered included: age, gender, residency/fellowship training location, time since training completion until FD appointment, length in FD role, and personal research H-index.
    RESULTS: We identified 103 FLs consisting of 67 FDs, 19 co-FDs, and another 16 individuals with a synonymous leadership title. 96.1% (99) of the leadership consisted of males while 3.9% (4) were female. The mean age was 52.9 years old and the mean h-index of the FLs was 23.8. FLs were trained in orthopaedic surgery (n = 89), neurosurgery (n = 13), or combined orthopaedic surgery and neurosurgery training (n = 1). The top fellowships programs producing future FLs were: Case Western Reserve University, Cleveland (n = 10), Washington University, St. Louis (n = 9), and Rothman Institute, Thomas Jefferson University, Philadelphia (n = 7).
    CONCLUSION: Spine surgery fellowship directors are more likely to have graduated from certain residency and fellowship programs. This finding could be a result of the training provided by these centers or the institution's predilection to select applicants that are more likely to later seek academic leadership roles post-training.

    Phytoremediation of Heavy Metal Pollution: A Bibliometric and Scientometric Analysis from 1989 to 2018.
    Chen Li, Xiaohui Ji, Xuegang Luo.
      This paper aims to evaluate the knowledge landscape of the phytoremediation of heavy metals (HMs) by constructing a series of scientific maps and exploring the research hotspots and trends of this field. This study presents a review of 6873 documents published about phytoremediation of HMs in the international context from the Web of Science Core Collection (WoSCC) (1989-2018). Two different processing software applications were used, CiteSpace and Bibliometrix. This research field is characterized by high interdisciplinarity and a rapid increase in the subject categories of engineering applications. The basic supporting categories mainly included "Environmental Sciences & Ecology", "Plant Sciences", and "Agriculture". In addition, there has been a trend in recent years to focus on categories such as "Engineering, Multidisciplinary", "Engineering, Chemical", and "Green & Sustainable Science & Technology". "Soil", "hyperaccumulator", "enrichment mechanism/process", and "enhance technology" were found to be the main research hotspots. "Wastewater", "field crops", "genetically engineered microbes/plants", and "agromining" may be the main research trends. Bibliometric and scientometric analysis are useful methods to qualitatively and quantitatively measure research hotspots and trends in phytoremediation of HM, and can be widely used to help new researchers to review the available research in a certain research field.

    For the further training of individuals in neurosurgery II: the academic legacy of the William P. Van Wagenen Fellowship.
    D Ryan Ormond, Mohab Abozeid, Shekar Kurpad, Stephen J Haines.
       OBJECTIVE: William P. Van Wagenen pursued a research fellowship in Europe early in his career under the recommendation of Harvey Cushing. Later, Van Wagenen would be instrumental in the establishment of the William P. Van Wagenen Fellowship, a postgraduate fellowship for neurosurgeons from the AANS that requires study outside of a fellow's country of residency training with plans to return to academic practice.
    METHODS: Since 1968, 54 Van Wagenen Fellowships have been awarded, sending 54 fellows from 31 institutions to 13 different countries. The academic productivity of fellows was studied to determine the academic "return on investment" of the fellowship.
    RESULTS: Almost all fellows have spent some time in academic neurosurgery (94%), with the vast majority remaining in academics for their entire career (87%); 52% of fellows have received NIH funding, and 55% have been promoted to professor. The numbers are even more striking for the first half of Van Wagenen Fellows (who received the fellowship from its inception in 1968 to 1994) with at least 25 years of career development who remained in academics: 65% received NIH funding, 86% were promoted to professor, and 62% became chairs of academic departments. The Hirsch index of fellows, defined as h papers from an individual with at least h citations, is higher than the national mean and median values for academic neurosurgeons at every academic rank. Fellows have served on national committees and as AANS and CNS presidents and have given back financially to the Neurosurgery Research and Education Foundation (NREF) to fund future research activities of neurosurgical residents and young faculty.
    CONCLUSIONS: The Van Wagenen Fellowship will continue to provide young neurosurgeons with opportunities to pursue novel research and network with peers internationally and to motivate young neurosurgeons to transform neurosurgery. The legacy of Cushing and Van Wagenen continues today through the Van Wagenen Fellowship, a legacy that will only continue to grow.

    A comparative evaluation of the publications of French public teaching hospitals from 2004 to 2014.
    Emeline Blanc, Roselyne Boulieu, Delphine Bertram.
      Care, teaching, and research are all priorities of the French public teaching hospitals. In 2004, the remuneration method evolved from a global endowment to a fee-for-services system, based on the use of bibliometric tools. These were used in the present study to describe the research patterns of public teaching hospitals in regards to care and teaching activities. The present study was based on data from the 32 French public teaching hospitals, between 2004 and 2014. Records concerning the publications number, hospital stays, full-time equivalent (FTE) practitioners, and residents per FTE physician were accessed. Statistical analyses were performed using means, Pearson correlation coefficients, and regression lines. The mean number of publications per FTE physician was 0.73, the mean number of hospital stays per FTE physician was 235.8 and the mean number of residents per FTE physician was 0.63. There was a moderate positive correlation between the number of publications per FTE physician and the number of residents per FTE physician (R=0.53) and a negligible correlation between the number of residents per FTE physician and the number of hospital stays per FTE physician (R=0.12). There was a low negative correlation between publication numbers per FTE physician and the number of stays per FTE physician (R=-0.41). All public teaching hospitals presented different patterns in terms of care, teaching, and research activities. None of the 32 hospitals performed well in all three activities. Only nine performed well in at least two out of the three missions.

    Being there: A scoping review of grief support training in medical education.
    Laura Sikstrom, Riley Saikaly, Genevieve Ferguson, Pamela J Mosher, Sarah Bonato, Sophie Soklaridis.
       INTRODUCTION: Medical education experts argue that grief support training for physicians would improve physician and patient and family wellness, and should therefore be mandatory. However, there is little evidence about the range of curricula interventions or the impact of grief training. The aim of this scoping review was to describe the current landscape of grief training worldwide in medical school, postgraduate residency and continuing professional development in the disciplines of pediatrics, family medicine and psychiatry.
    METHODS: Using Arksey and O'Malley's scoping review principles, MEDLINE, EMBASE, ERIC, PsychInfo and Web of Science were searched by a librarian. Two levels of screening took place: a title and abstract review for articles that fit a predefined criteria and a full-text review of articles that met those criteria. Three investigators reviewed the articles and extracted data for analysis. To supplement the search, we also scanned the reference lists of included studies for possible inclusion.
    RESULTS: Thirty-seven articles published between 1979 and 2019 were analyzed. Most articles described short voluntary grief training workshops. At all training levels, the majority of these workshops focused on transmitting knowledge about the ethical and legal dimensions of death, dying and bereavement in medicine. The grief trainings described were characterized by the use of diverse pedagogical tools, including lectures, debriefing sessions, reflective writing exercises and simulation/role-play.
    DISCUSSION: Grief training was associated with increased self-assessed knowledge and expertise; however, few of the studies analyzed the impact of grief training on physician and patient and family wellness. Our synthesis of the literature indicates key gaps exist, specifically regarding the limited emphasis on improving physicians' communication skills around death and dying and the limited use of interactive and self-reflexive learning tools. Most trainings also had an overly narrow focus on bereavement grief, rather than a more broadly defined definition of loss.

    Publication rates in animal research. Extent and characteristics of published and non-published animal studies followed up at two German university medical centres.
    Susanne Wieschowski, Svenja Biernot, Susanne Deutsch, Silke Glage, André Bleich, René Tolba, Daniel Strech.
      Non-publication and publication bias in animal research is a core topic in current debates on the "reproducibility crisis" and "failure rates in clinical research". To date, however, we lack reliable evidence on the extent of non-publication in animal research. We collected a random and stratified sample (n = 210) from all archived animal study protocols of two major German UMCs (university medical centres) and tracked their results publication. The overall publication rate was 67%. Excluding doctoral theses as results publications, the publication rate decreased to 58%. We did not find substantial differences in publication rates with regard to i) the year of animal study approval, ii) the two UMCs, iii) the animal type (rodents vs. non-rodents), iv) the scope of research (basic vs. preclinical), or v) the discipline of the applicant. Via the most reliable assessment strategy currently available, our study confirms that the non-publication of results from animal studies conducted at UMCs is relatively common. The non-publication of 33% of all animal studies is problematic for the following reasons: A) the primary legitimation of animal research, which is the intended knowledge gain for the wider scientific community, B) the waste of public resources, C) the unnecessary repetition of animal studies, and D) incomplete and potentially biased preclinical evidence for decision making on launching early human trials. Results dissemination should become a professional standard for animal research. Academic institutions and research funders should develop effective policies in this regard.

    Publishing trends in velopharyngeal insufficiency.
    Charles Poff, Joshua Horton, Ryan Boerner, Alex Marston, Shaun A Nguyen, David R White.
       OBJECTIVE: This study seeks to describe publishing trends for VPI over a 33-year span with regard to treating specialty, methods of assessment, related diagnoses, and methods of treatment for each specialty.
    METHODS: A PubMed search was performed on "velopharyngeal insufficiency" using medical subject headings terms from 1985 to 2017. Publisher specialty, method(s) of VPI assessment, associated diagnosis/diagnoses, and method(s) of VPI treatment per specialty and combined across specialties were analyzed. Respective publications were totaled in 11-year intervals and two-way analysis of variance was used to compare change over time within specialties and across specialties.
    RESULTS: 763 publications were included for analysis. The total number of publications on VPI increased from a total of 6 in 1985 to a peak of 67 in 2015. The specialties that showed the largest increase in relative frequency of publication were Otolaryngology (p < 0.001), Plastic Surgery (p < 0.001), and Multidisciplinary (p < 0.001). Publications on endoscopic (p < 0.001) evaluation of VPI have significantly increased over time relative to magnetic resonance imaging and lateral cephalometry. Across all specialties, publications that feature pharyngoplasty (p < 0.001), palatoplasty (p < 0.001), and pharyngeal flap (p < 0.001) as methods of VPI treatment have significantly increased over time.
    CONCLUSION: There is a trend towards endoscopy for diagnostics and a multidisciplinary approach when managing patients with VPI. The specialty that showed the largest increase in the relative frequency of publication was Otolaryngology. Surgical methods of treatment continue to be described at increasing frequency relative to more conservative treatments.
