      BACKGROUND: The purpose of this study is to comprehensively analyze the global application trend of high tibial osteotomy (HTO) and identify promising research hotspots of HTO based on bibliometrics and visual analysis.METHODS: Publications (articles and reviews) related to HTO from 2001 to 2020 were retrieved from the Web of Science Core Collection database (WOSCC). The country, institution, year, author, journal, average citations per item, H index, title, abstract, keywords of publication, and the top 10 cited articles were extracted and analyzed in detail. The VOSviewer software was used to analyze theco-occurrence of keywords to predict the hotspots of HTO.
    RESULTS: A total of 1883 articles were included. In the past 20 years, the number of HTO articles has shown an increasing trend in general. The top 3 countries (the USA, Germany, and South Korea) accounted for 49.547% of all articles published. The USA has the largest number of publications. The University of Western Ontario is the largest contributor. The Knee Surgery Sports Traumatology Arthroscopy is the most influential journal. Professors Saito T and Imhoff AB are the leading scholars who made great achievements in the HTO field. The research direction can be divided into the following 5 clusters: "prognosis and outcome", "HTO combined with cartilage restoration techniques", "animal experimental research", "study on bone union and plate fixation at osteotomy", and "surgical technique research".
    CONCLUSION: In terms of the trend of previous years, an increasing number of literatures related to HTO will be published in the future. The USA is a world leader in the field of HTO. South Korea presented great potential in this area. HTO combined with cartilage restoration techniques, postoperative prognosis and outcome, and surgical technique research may be the future hotspots in the field of HTO research.

      INTRODUCTION: Meta-analyses provide high-level evidence and understanding their trends may provide understanding of the field as a whole. Bibliometric analysis was undertaken to understand research trends in a particular field or subfield and to assess citation as a measure of impact.METHODS: All journals categorised as "Radiology, Nuclear Medicine & Medical Imaging" under the Web of Science subject category were included. After analyzing impact factors of the journals in up to 2018, the top five journals were identified. The retrieved results were ordered by citation count based on Web of Science and Scopus. Specific parameters regarding the title, journal, publication year, authors, country of origin, institution and university, field of study and funding sources were analyzed.
    RESULTS: A total of 139 articles were identified. The mean number of citations per article was 25.3 and 22.6 in Scopus and Web of Science respectively, with four articles receiving 100 or more citations. European Radiology had the greatest number of top cited articles (n = 68; 49%). Most number of articles originated from South Korea (n = 60; 43%) and the commonest field of focus with the most common being oncology (n = 51; 27%).
    CONCLUSION: The top 5 high impact journals published a large number of meta-analysis and systematic reviews. The greatest number of top-cited articles were from South Korea, shifting away from the United States. Large number of studies focused on oncologic imaging, consistent with recent trends towards development of imaging biomarkers and personalized medicine. Author H index did not predict citation number or density.

      Background: Many articles on bone morphogenetic proteins (BMPs) have been published. Bibliometric analysis is helpful to determine the most influential studies in a specific field. This bibliometric analysis is aimed at identifying and analyzing the top 50 most-cited articles on the dental applications of BMPs.Methods: An electronic search was conducted using the Web of Science (WoS) "All Databases" without any restriction of language, study design, or publication year. Of 1341 publications, the top 50 were included based on their citation count. After downloading the full texts, their bibliometric data including publication title, authorship, citation count, current citation index 2019, citation density, year of publication, country and institution of origin, journal of publication, type of BMP, study design, evidence level of publication, and keywords were extracted and analyzed.
    Results: The citation counts for the top 50 publications ranged from 81 to 557 (median 113.5). The most prolific year was 1997 (n = 7). Wikesjö UM (n = 12) and Wozney JM (n = 11) were the major contributors in this study. Most of the articles were generated primarily from the USA (n = 24), with Loma Linda University Medical Center, USA being the most prolific institution (n = 5). Majority of the articles were published in the Clinical Oral Implants Research and Journal of Periodontology, with nine publications each. Most of the publications were animal studies (n = 30) and focused on BMP-2 (n = 39). Most of the articles were within evidence level V (n = 36). The most frequently used keyword in the top articles was "bone regeneration" (n = 23).
    Conclusion: The present study presents insights into the past and recent trends in the applications of BMPs in dentistry. A statistically significant association was observed between citation count, citation density, and age of publication.

      AIMS: To identify and analyze the 100 most cited articles on nursing student education (NSE) that were published in nursing journals.BACKGROUND: The citation frequency of an article indicates its scientific impact. Analyzing highly cited articles on NSE enabled researchers to identify mainstream research types and acquire relevant information and knowledge.
    DESIGN: A retrospective bibliometric analysis with co-citation network analysis.
    DATA SOURCES: We searched for journal articles on NSE from the Web of Science, and analyzed the 100 most cited articles (date of search: June 3, 2020).
    REVIEW METHODS: The theme, article type, journal, country, source of institutional articles, and publication year were counted and analyzed. The citation relationships among the most 100 cited articles of NSE were calculated and visualized.
    RESULTS: Articles included in this study were mostly empirical quantitative studies with a cross-sectional design, and were published in international nursing journals between 2000 and 2020. Their authors were mostly from the United States and the United Kingdom. According to the co-citation network analysis, four main research directions were identified: workplace mental health, simulation learning, spiritual care, and medication administration.
    CONCLUSION: Workplace mental health was the major research topic on NSE. This research topic has spanned two decades (2000-2020). These articles were mainly published in the Journal of Advanced Nursing and Nurse Education Today. Some recent research topics, such as simulation learning and spiritual care were also identified. Findings provide a fresh review of the highly cited NSE articles, including the visualization of the NSE network.

      OBJECTIVE: Publications are key for advancement within academia. Although women are underrepresented in academic neurosurgery, the rates of women entering residency, achieving board certification, and publishing papers are increasing. The goal of this study was to assess the current status of women in academic neurosurgery publications. Specifically, this study sought to 1) survey female authorship rates in the Journal of Neurosurgery (JNS [not including JNS: Spine or JNS: Pediatrics]) and Neurosurgery from 2010 to 2019; 2) analyze whether double-blind peer review (started in Neurosurgery in 2011) altered female authorship rates relative to single-blind review (JNS); and 3) evaluate how female authorship rates compared with the number of women entering neurosurgery residency and obtaining neurosurgery board certification.METHODS: Genders of the first and last authors for JNS and Neurosurgery articles from 2010 to 2019 were obtained. Data were also gathered on the number and percentage of women entering neurosurgery residency and women obtaining American Board of Neurological Surgeons (ABNS) certification between 2010 and 2019.
    RESULTS: Women accounted for 13.4% (n = 570) of first authors and 6.8% (n = 240) of last authors in JNS and Neurosurgery publications. No difference in rates of women publishing existed between the two journals (first authors: 13.0% JNS vs 13.9% Neurosurgery, p = 0.29; last authors: 7.3% JNS vs 6.0% Neurosurgery, p = 0.25). No difference existed between women first or last authors in Neurosurgery before and after initiation of double-blind review (p = 0.066). Significant concordance existed between the gender of first and last authors: in publications with a woman last author, the odds of the first author being a woman was increased by twofold (OR 2.14 [95% CI 1.43-3.13], p = 0.0001). Women represented a lower proportion of authors of invited papers (8.6% of first authors and 3.1% of last authors were women) compared with noninvited papers (14.1% of first authors and 7.4% of last authors were women) (first authors: OR 0.576 [95% CI 0.410-0.794], p = 0.0004; last authors: OR 0.407 [95% CI 0.198-0.751], p = 0.001). The proportion of women US last authors (7.4%) mirrors the percentage of board-certified women neurosurgeons (5.4% in 2010 and 6.8% in 2019), while the percentage of women US first authors (14.3%) is less than that for women entering neurosurgical residency (11.2% in 2009 and 23.6% in 2018).
    CONCLUSIONS: This is the first report of female authorship in the neurosurgical literature. The authors found that single- versus double-blind peer review did not impact female authorship rates at two top neurosurgical journals.

      BACKGROUND Cardiopulmonary resuscitation (CPR) is a topic of great scientific and clinical interest that has received much attention in the past decade. Our study aimed to predict the trends in CPR research activities and evaluate hot topics via bibliometric means, quantitatively and qualitatively. MATERIAL AND METHODS All data were collected from a search of the Web of Science Core Collection on May 12, 2020. Retrieved information was investigated with bibliometric analysis by CiteSpace and VOSviewer software and the Online Analysis Platform of Literature Metrology to analyze and predict the trends and hotspots in this field. RESULTS Our search returned a total of 9563 articles and reviews on CPR published from 2010 through 2019. The number of original research studies on CPR has been increasing annually. The journal Resuscitation published the greatest number of manuscripts involved CPR, and the leading country and institution with regard to contributions on CPR were the United States and the University of Pennsylvania. Keyword co-occurrence/co-citation-cluster analysis showed that the most popular terms associated with CPR occurred in the manner of cluster labels, such as therapeutic hypothermia and treatment recommendation, among others. In addition, palliative care, sepsis, extracorporeal membrane oxygenation, and brain injury were identified as new foci through burst detection analysis. CONCLUSIONS Our study showed that the scientific research focus on CPR is switching from traditional therapeutic treatments to a public health practice, with in-depth understanding and development of CPR-related techniques expanding over the past decade. These results demonstrate trends in the CPR research and detected the possible neo-foci for ensuing research.

      Network Meta-analysis has been widely applied in the field of traditional Chinese medicine(TCM) due to its unique advantages. This study aimed to conduct a visual analysis on the state of the application network Meta-analysis in the field of traditional Chinese medicine. Databases of CNKI and Web of Science were retrieved to identify the qualified literatures and then screen out their titles and abstracts. Institutions, authors, cited references, and keywords were analyzed using the information visualization analysis software CiteSpace. Finally, 79 English and 186 Chinese articles were included. The results indicated that the literatures were mainly published in Chinese, and the number of articles was increased rapidly since 2015. Cooperation between institutions and authors were mainly concentrated inside the institutions. The most important four institutions were four universities who attached more importance to evidence-based medical education and academic exploration. The keywords beside the method of network Meta-analysis could be summarized into three types: the main interventions in traditional Chinese medicine(Chinese herbal injection, herb medicine, acupuncture, etc.), disease types(cancer, circulatory system disease, bone joint disease, urinary system disease, etc.) and the outcome of interests(efficacy, safety, symptom, survive, mortality, etc.), which reflected the current research hotspots to certain extent. In addition, the most cited articles were methodology articles, including the introduction of methodology and the guides of application software, suggesting that the exploration of methodological articles will be extremely concerned.

      Objective: Medical errors represent a leading cause of patient morbidity and mortality. The aim of this study was to quantitatively analyze the existing scientific literature on medical errors in order to gain new insights in this important medical research area. Study Design: Web of Science database was used to identify relevant publications, and bibliometric analysis was performed to quantitatively analyze the identified articles for prevailing research themes, contributing journals, institutions, countries, authors, and citation performance. Results: In total, 12,415 publications concerning medical errors were identified and quantitatively analyzed. The overall ratio of original research articles to reviews was 8.1:1, and temporal subset analysis revealed that the share of original research articles has been increasing over time. The United States contributed to nearly half (46.4%) of the total publications, and 8 of the top 10 most productive institutions were from the United States, with the remaining 2 located in Canada and the United Kingdom. Prevailing (frequently mentioned) and highly impactful (frequently cited) themes were errors related to drugs/medications, applications related to medicinal information technology, errors related to critical/intensive care units, to children, and mental conditions associated with medical errors (burnout, depression). Conclusions: The high prevalence of medical errors revealed from the existing literature indicates the high importance of future work invested in preventive approaches. Digital health technology applications are perceived to be of great promise to counteract medical errors, and further effort should be focused to study their optimal implementation in all medical areas, with special emphasis on critical areas such as intensive care and pediatric units.

      BACKGROUND: Despite an increase in the number of practicing female physicians, gender disparities in academic medicine persist. For investigating gender gap in the transplantation field, this study examined the relationship between gender and authorship among medical and surgical transplant physicians.MATERIALS AND METHODS: In this observational study, all original clinical science articles published in the journals of Transplantation, American Journal of Transplantation, and Clinical Transplantation were reviewed from January 2008 to December 2017. Chi-square analysis was used to compare the proportions of female and male authors, and the Cochrane-Armitage test was used for comparisons over time.
    RESULTS: A total of 2530 publications and 2988 individual authors met the inclusion criteria for the study. Male physicians published significantly more articles compared to female physicians as first (67.4% versus 30.4%) and senior authors (82.9% versus 16.2%), respectively. There were increases in the proportion of female first and senior authors between 2008 and 2017. The majority of authors with multiple publications were male (73.6%), specifically male medical physicians (44.3%). Male medical physicians were the most productive in publication amount and authorship positions.
    CONCLUSIONS: While research activity among female physicians increased over time, gender disparity continues to exist among female and male physicians in the transplantation field. Academic activity is lower among females in publication amount and authorship positions. These trends emphasize the need to identify barriers to female physician academic productivity within the transplantation field.

      OBJECTIVE: Women are becoming more prevalent in clinical neuropsychology, but gender bias and disparities persist across multiple professional domains. This study examined potential gender disparities in historical authorship trends across commonly read journals in clinical neuropsychology. Method: Analyses were conducted on 10,531 articles published in six clinical neuropsychology journals from 1985 to 2019. Each author was coded as either a man or a woman using the OpenGenderTracking Project database. Results: On average, women comprised 43.3% (±30.6) of the authors listed in clinical neuropsychology article bylines and were lead and/or corresponding author on 50.3% of these papers. Findings varied by journal, with Child Neuropsychology having the best representation of women across several study metrics. Women comprised an increasing proportion of authors over time and the gender gap in clinical neuropsychology is smaller than was recently reported for the broader field of psychology; nevertheless, the recent rates of women as authors lag behind the prevalence of women in clinical neuropsychology. Encouragingly, gender was not associated with the number of times an article was cited. Articles that included women in leadership roles had significantly more authors overall and specifically more women authors. Conclusions: Women are under-represented as authors in clinical neuropsychology journals, but they are becoming more common and their papers are cited just as frequently as men. Efforts to increase women as research mentors and sponsors may help to further close the publishing gender gap in clinical neuropsychology.

      BACKGROUND: Retracted articles continue to be cited after retraction, and this could have consequences for the scientific community and general population alike. This study was conducted to analyse the association of retraction on citations received by retracted papers due to misconduct using two-time frames: during a postretraction period equivalent to the time the article had been in print before retraction; and during the total postretraction period.METHODS: Quasiexperimental, pre-post evaluation study. A total of 304 retracted original articles and literature reviews indexed in MEDLINE fulfilled the inclusion criteria. Articles were required to have been published in a journal indexed in MEDLINE from January 2013 through December 2015 and been retracted between January 2014 and December 2016. The main outcome was the number of citations received before and after retraction. Results were broken down by journal quartile according to impact factor and the most cited papers during the preretraction period were specifically analysed.
    RESULTS: There was an increase in postretraction citations when compared with citations received preretraction. There were some exceptions however: first, citations received by articles published in first-quartile journals decreased immediately after retraction (p<0.05), only to increase again after some time had elapsed; and second, postretraction citations decreased significantly in the case of articles that had received many citations before their retraction (p<0.05).
    CONCLUSIONS: The results indicate that retraction of articles has no association on citations in the long term, since the retracted articles continue to be cited, thus circumventing their retraction.

      BACKGROUND: The impact of residency training on academic productivity and a career in academic plastic surgery remains uncertain. Previous literature has explored the influence of training institutions on academic careers in surgery. The aims of the study were to assess research productivity during plastic surgery residency training and to illustrate how differences in training programs impact resident research productivity.METHODS: Academic plastic surgery faculty that graduated in the past 10 years were identified through an Internet search of all Accreditation Council for Graduate Medical Education-accredited residency and fellowship training programs. Research productivity was compared based on h-index, number, and quality of peer-reviewed articles published during residency.
    RESULTS: Three hundred seventy-five academic plastic surgeons were identified and produced 2487 publications during residency. The 10 most productive training institutions were Johns Hopkins, Georgetown, University of Michigan, Stanford, University of California Los Angeles, Northwestern, Harvard, New York University, University of Pennsylvania, and Baylor. Academic productivity was higher among integrated residents (integrated = 8.68 publications, independent = 5.49 publications, P < 0.0001). The number of publications positively correlated to faculty size (r = 0.167, P = 0.0013), National Institute of Health (NIH) funding (r = 0.249, P < 0.0001), residency graduation year (r = 0.211, P < 0.0001), and negatively correlated with Doximity ranking (r = -0.294, P < 0.0001). H-index was positively correlated with number of publications (r = 0.622, P < 0.0001), faculty size (r = 0.295, P < 0.0001), and NIH funding (r = 0.256, P < 0.0001) and negatively correlated with Doximity ranking (r = -0.405, P < 0.0001) and residency graduation year (r = -0.163, P < 0.0001).
    CONCLUSIONS: Our study has found that there is an elite cohort of programs that are the most productive research institutions. Resident research productivity is higher among integrated residents, recent graduates, and programs that are larger in size, with a higher Doximity ranking and NIH funding. This study can guide medical students and future applicants who are interested in a career in academic plastic surgery in the selection of programs that match their career aspirations.

      INTRODUCTION: Graduate medical education (GME) faculty and trainees have required scholarly activities to meet accreditation requirements. The impact of this contribution to the Military Health System, especially regarding innovations in military medicine, has not been previously examined. This study measured the contribution of GME in published manuscripts from a tertiary military medical center.MATERIALS AND METHODS: Utilizing the Scopus database, published manuscripts from the primary military GME institutions for the San Antonio Uniformed Services Health Education Consortium were identified from 2008 to 2018. Manuscripts were sorted based on the number of citations in Scopus and analyzed for their overall impact in medicine to include military unique topics.
    RESULTS: A total of 3,700 manuscripts were identified through Scopus and based on a 10 citation minimum, 1,365 manuscripts were further analyzed; 1,152 (84.4%) included authors with GME affiliation and 554 (40.6%) had direct applicability to unique aspects of military medicine. The mean number of citations per manuscript was 39.2 ± 63.6; Mean Cite Score was 2.97 ± 2.14 and Field Weighted Citation Index of 2.22 ± 3.27. Analysis of number of citations (10-19; 20-39; or >40) did not show any significant differences in Cite Score or military relevance, whereas the percentage of military relevant articles remained consistent yearly.
    CONCLUSIONS: These findings highlight the importance of military medical research and addressing specific medical needs of the warfighter. Graduate medical education in a tertiary Military Health System facility has enormous impact in scholarly activity, in particular the importance related to military medicine topics that emphasize combat casualty care and military readiness.

      BACKGROUND: Family medicine is a relatively new academic medical discipline. We aimed to compare the main bibliometric indices of hospital-based senior physicians practicing internal medicine versus family medicine in Switzerland.METHODS: We conducted this cross-sectional study in March 2020. We selected all hospital-based senior physicians practicing internal medicine or family medicine in the six Swiss university hospitals. Using Web of Science, after removing from both groups of physicians the 5% with the highest number of publications, we extracted the number of publications, the number of publications per year, the number of citations, the number of citations per year, the number of citations per publication and the h-index. We compared the data between the two groups using negative binomial regressions and the proportion of physicians having at least one publication using chi-square tests.
    RESULTS: We included 349 physicians in the study (internal medicine: 51%, men: 51%). The median number of publications was three [interquartile range (IQR) = 18], the median number of citations was nine (IQR = 158) and the median h-index was one (IQR = 5). All bibliometric indices were similar in both groups, as was the proportion of physicians having at least one publication (family medicine: 87% versus 82%, P = 0.15).
    CONCLUSIONS: We found no association between the bibliometric indices and the medical specialty. Further studies are needed to explore other important indicators of academic output, such as those more specifically assessing its quality and scientific importance.

      PURPOSE: Studies conducted in medical fields other than family medicine show that gender differences in publication rates are pronounced in many, but not all, fields of medicine. Our objective was to assess possible gender differences in publication rates in family medicine journals.METHODS: Using MEDLINE, we collected information on all journal articles published in 3 family medicine journals in the United States (Family Medicine, Journal of the American Board of Family Medicine, and Annals of Family Medicine) during the period 2008 to 2017. Gender of first and last author for each article was assigned using first names. The gender breakdown of the editorial boards during this time period was also examined.
    RESULTS: For the 3 journals combined during the period 2008 to 2017, 46.1% (1,209/2,623) of first authors were female, and 38.6% (857/2,223) of last authors were female. For all journals combined, there was a statistically significant increase in first authorship (43.2% in 2008 vs 52.1% in 2017; P<.001) and last authorship (28.8% in 2008 vs 41.8% in 2017; P <.001) over time. The editorial boards of the journals combined were 37.2% (279/749) female, and this did not increase significantly over the time period studied (35.5% in 2008 vs 39.2% in 2017; P=.49).
    CONCLUSIONS: Representation of female authors in family medicine journals is increasing, yet last authorship remains low, and there is variation between journals in terms of gender equity. Future studies can evaluate the reason for these differences and offer solutions to publications as they try to increase their female authorship.

      The embedding microbial fuel cell (MFC) into constructed wetlands (CW) to form CW-MFC bears the potential to obtain bioelectricity and a clean environment. In this study, a bibliometric analysis using VOSviewer based on Web of Science data was conducted to provide an overview by tracing the development footprint of this technology. The countries, institutions, authors, key terms, and keywords were tracked and corresponding mapping was generated. From 2012 to September 2020, 442 authors from 129 organizations in 26 countries published 135 publications in 42 journals with total citation of 3139 times were found. The key terms analysis showed four clusters: bioelectricity generation performance, mechanism study, refractory pollutants removal, and enhanced conventional contaminants removal. Further research themes include exploring the biochemical properties of electrochemically active bacteria, emerging contaminants removal, effective bioelectricity harvest and the use, and biosensor development as well as scaling-up for real field application. The bibliometric results provide valuable references and information on potential research directions for future studies.

      Systematic assessment of scientific events has become increasingly important for research communities. A range of metrics (e.g., citations, h-index) have been developed by different research communities to make such assessments effectual. However, most of the metrics for assessing the quality of less formal publication venues and events have not yet deeply investigated. It is also rather challenging to develop respective metrics because each research community has its own formal and informal rules of communication and quality standards. In this article, we develop a comprehensive framework of assessment metrics for evaluating scientific events and involved stakeholders. The resulting quality metrics are determined with respect to three general categories-events, persons, and bibliometrics. Our assessment methodology is empirically applied to several series of computer science events, such as conferences and workshops, using publicly available data for determining quality metrics. We show that the metrics' values coincide with the intuitive agreement of the community on its "top conferences". Our results demonstrate that highly-ranked events share similar profiles, including the provision of outstanding reviews, visiting diverse locations, having reputed people involved, and renowned sponsors.

      OBJECTIVES: To explore the relationship between research time during urologic training and career academic success.METHODS: We included urologists graduating residency between 2002 to 2008 from 36 programs affiliated with a top 50 hospital for urology as ranked by the U.S. News and World Report, and collected research time during residency, fellowship training, current appointment (private practice, assistant professor, associate professor, professor, chair), NIH grant accrual, NIH R01 grant accrual, and current H-index in Scopusࣨ database. Publication output during and after residency was identified through the PubMed database.
    RESULTS: In our cohort of 543 urologists, 66.3% of graduating trainees pursued private practice. Increasing residency research time was associated with increased publication count (p<.001), pursuit of professor positions (p<.001), and NIH funding (p<.001). One year of dedicated research increased the odds of being in the top 10th percentile of publication output during residency (OR: 5.7, 95% CI: 2.7-12.1), pursuing a fellowship (OR: 2.0, 95% CI: 1.3-3.1), promotion to professor (OR: 4.9, 95% CI: 2.0-12.2), obtaining a NIH grant (OR: 6.2, 95% CI: 2.3-16.5), and decreased the odds of pursuing private practice (OR: 0.4, 95% CI: 0.3-0.6). As amount of time dedicated to research in urologic residency increased from 3-4 to 6 to 12 months, odds ratios increased for career academic success metrics.
    CONCLUSIONS: Although a minority of trainees enter academics, dedicated time for research in urologic residency is associated with career academic success, with more research time associated with increased publication output, academic appointments, and grant funding.

      To analyze the study advance of Cichorium intybus, a kind of medicinal food, this study systematically retrieved Chinese and English literatures of C.intybus-related studies based on CNKI and the Web of Science database platforms by literature metrological research method and CiteSpace 5.5.R2 software, and visualized the literatures. A total of 1 247 Chinese literatures and 1 488 English literatures were included. Author analysis showed that HAN Yongfen in Guizhou Grass Industry Research Institute and W VAN DEN ENDE in Belgium Catholic University of Leuven had the most publications in Chinese and English C.intybus literatures respectively. ZHANG Bing's team was the core study team of C. intybus in China. Beijing University of Chinese Medicine and Belgium Catholic University of Leuven had the largest number of Chinese and English Cichorium literatures. There was a few cooperation between Chinese study institutions and close cooperation between foreign research institutions. Keywords analysis showed that C.intybus studies mainly focused on breeding and growth performance, composition analysis and content determination, nutritional value and medicinal value, in which C.intybus composition and its role in reducing uric acid were the hotspots of current studies. This study found that C.intybus has a high economic value and medicinal value, and its food nutrition and medicinal activity will be the main directions of future studies.

      OBJECTIVES: For more than twenty years, dental practice-based research networks (D-PBRN) have helped to structure clinical research in private practice. They bring together practitioners working in several structures and may include a greater number of subjects. The aims of this study were thus to systematically explore the scientific production from dental private practices in general and to map and describe the D-PBRN activity worldwide.DATA SOURCES: Two research procedures were carried out in parallel. The first was conducted as a scoping review to examine peer-reviewed literature indexed in the PubMed database and the second was performed on the World Wide Web to identify the main characteristics of the networks (location, scientific production…).
    STUDY SELECTION: 368 publications were identified among which 202 were published by PBRN members and the others by private practitioners not affiliated to any network. 210 (57% of the included articles) were produced in the USA. A higher number of diverse centers are involved in each study when it is conducted by a PBRN (59.06 ± 66.59 vs. 13.51 ± 31.58 for networks and independent teams, respectively; p < 0.01). 24 D-PBRN were identified, a majority being based in the USA and 8 in Europe.
    CONCLUSIONS: Although dental practice-based research has grown over the years, the number of D-PBRN worldwide remains low. Even if it requires some investment to produce research in dental offices, this type of networks helps to fill the gap between private practice and research and to improve knowledge on oral health.
    RELEVANCE: The mapping of all the dental PBRN together with the research topics studied throughout the world make the relevance of this article. The ways to improve practice-based research in dentistry are also discussed in the paper.

      Purpose: Given the long history of investigation into cancer and its relevance to the lymph node (LN), it would be meaningful to plot the trends of research on cancer-related LN.Methods: Queries such as "cancer," "lymph node," and "cancer and lymph node" were submitted to PubMed to collect articles on cancer and LN published between 1945 and 2017. The collected articles were then extracted by an automatic web crawler and examined through informetrics and linguistic analysis.
    Results: The number of articles related to cancer was 2,795,476 and 127,897 articles (4.6%) were found to be relevant to LN. With regard to cancer types, breast cancer was the most studied (37%), followed by gastric cancer (17%). With regard to the subjects in which the surgeon is interested, LN metastasis (57%) was found to be the topic most discussed, followed by LN dissection (22%) and sentinel LN (17%). Publications on LN metastasis gradually increased over time from 1988 to 2017 although those on sentinel LN and LN dissection have stagnated since the early 2000s.
    Conclusion: Although research on cancer was abundant, only a small portion was dedicated to investigating its relevance to LN. Western countries had led the research on cancer-related LN, but Asian countries began to participate as major players, expanding their contributions. While LN metastasis, one of the major cancer-related LN topics, showed a steady increase, those involved in oncologic surgery such as LN dissection and sentinel LN did not.

      OBJECTIVE: The proportion of women in otolaryngology-head and neck surgery (OHNS) has steadily increased in recent years. This study examines gender representation in recognition awards given by OHNS societies between 2009 and 2019.STUDY DESIGN: Retrospective analysis of recognition awards given by 10 OHNS societies between 2009 and 2019.
    SETTING: Retrospective review of web-based, public records.
    METHODS: Data from 19 awards were analyzed for recipient gender ratio, society, subspecialty, award type (research, achievement, or humanitarian), and change over time.
    RESULTS: Of 184 awards given by societies in otolaryngology-head and neck surgery, 59 (28%) were given to women. Women received 49 (28%) research awards, 9 (31%) humanitarian awards, and 1 (2.8%) achievement award. Women represented 31% of award winners in rhinology/skull base, 30% of award winners in head and neck surgery, 8% in neurotology, and 6% in facial plastic surgery. The American Head and Neck Society Prevention and Early Detection award had the highest representation of women at 43%. Some awards had no female awardees over the past decade. No temporal trends were observed.
    CONCLUSION: From 2009 to 2019, women received recognition awards at a higher percentage than overall gender representation in OHNS. Comparison of research, humanitarian, and achievement awards revealed the disparity of women receiving fewer achievement awards relative to men. Gender representation of award recipients varied by subspecialty, which may be partially determined by gender distribution within the fields.

      BACKGROUND: A diverse research workforce is essential for catalyzing biomedical advancements, but this workforce goal is hindered by persistent sex and racial/ethnic disparities among investigators receiving research grants from the National Institutes of Health (NIH). In response, the NIH-funded National Research Mentoring Network implemented a Grant Writing Coaching Program (GCP) to provide diverse cohorts of early-career investigators across the United States with intensive coaching throughout the proposal development process. We evaluated the GCP's national reach and short-term impact on participants' proposal submissions and funding outcomes.METHODS: The GCP was delivered as six similar but distinct models. All models began with an in-person group session, followed by a series of coaching sessions over 4 to 12 months. Participants were surveyed at 6-, 12- and 18-months after program completion to assess proposal outcomes (submissions, awards). Self-reported data were verified and supplemented by searches of public repositories of awarded grants when available. Submission and award rates were derived from counts of participants who submitted or were awarded at least one grant proposal in a category (NIH, other federal, non-federal).
    RESULTS: From June 2015 through March 2019, 545 investigators (67% female, 61% under-represented racial/ethnic minority, URM) from 187 different institutions participated in the GCP. Among them, 324 (59% of participants) submitted at least one grant application and 134 (41% of submitters) received funding. A total of 164 grants were awarded, the majority being from the NIH (93, 56%). Of the 74 R01 (or similar) NIH research proposals submitted by GCP participants, 16 have been funded thus far (56% to URM, 75% to women). This 22% award rate exceeded the 2016-2018 NIH success rates for new R01s.
    CONCLUSION: Inter- and intra-institutional grant writing coaching groups are a feasible and effective approach to supporting the grant acquisition efforts of early-career biomedical investigators, including women and those from URM groups.

      PURPOSE: When deciding among imaging equipment vendors, one may use a vendor's prevalence in peer-reviewed publications as a measure of their research and development. We sought to determine which vendors, countries, and journals were dominant in hepatic imaging literature of 2018 with respect to magnetic resonance (MR), computed tomography (CT), and ultrasound (US).METHODS: We recorded and analyzed the modality (MR, CT, US), journal, vendor, and authors' country for all original hepatic imaging articles published in 2018 in 29 imaging journals.
    RESULTS: Of 197 MR articles, investigators used Siemens in 98 (50%), General Electric (GE) in 65 (33%), and Philips in 63 (32%). Of 115 CT articles, investigators mentioned Siemens in 55 (48%), GE in 45 (39%), Philips in 25 (22%) and other vendors in 27 (24%). Of 68 ultrasound articles, Siemens dominated with 27 (40%), versus GE with 19 (28%), Philips with 11 (16%), and other vendors with 42 (62%). We found a significant difference in vendor usage for MR, CT, and all modalities (p < .01). The plurality of articles was written in the United States (73 [23%]) with South Korea (56 [17%]) and China (56 [17%]) following. European Radiology published the most hepatic articles. For American journals, we found a significant difference in MR (p = .02) and CT (p < .01) vendor usage, whereas non-American journals nearly reached significance in MR (p = .06) and CT (p = .06) vendor usage.
    CONCLUSION: Siemens was the most cited vendor in hepatic imaging literature for all modalities. American institutions and non-American journals published the most hepatic imaging articles.

      BACKGROUND: Racial and ethnic disparities have been clearly documented in schizophrenia studies, but it is unclear how much research attention they receive among US-based studies published in high-impact journals.AIMS: The current paper updates Lewine and Caudle's (1999) and Chakraborty and Steinhauer's (2010) works, which quantified how frequently schizophrenia studies included information on race and ethnicity in their analyses.
    METHOD: We examined all US-based papers on schizophrenia-spectrum, first-episode psychosis, and clinical high-risk groups, published between 2014 to 2016 in four major psychiatric journals: American Journal of Psychiatry, Journal of the American Medical Association - Psychiatry, Schizophrenia Bulletin, and Schizophrenia Research.
    RESULTS: Of 474 US-based studies, 62% (n = 295) reported analyses by race or ethnicity as compared to 20% in Lewine and Caudle's (1999) study. The majority of papers (59%) reported sample descriptions, a 42% increase from Lewine and Caudle's (1999) study. Additionally, 47% matched or compared the racial/ethnic composition of primary study groups and 12% adjusted for race (e.g., as a covariate). However, only 9% directly analyzed racial and/or ethnic identity in relation to the primary topic of the paper.
    CONCLUSIONS: While schizophrenia studies report analyses by race and ethnicity more frequently than 20 years ago, there remains a strong need for systematic, nuanced research on this topic. The authors offer recommendations for how to conceptualize and report upon race and ethnicity in schizophrenia research.
