RESUMO

Bisphenol A (BPA) is a well-known endocrine-disrupting chemical which can cause potential health risks and interfere with thyroid hormones through multiple avenues. This study aimed to evaluate the hotspots and emerging trends on BPA and thyroid hormones by using a bibliometric method.Publications related on BPA and thyroid hormones were downloaded from Science Citation Index-Expanded database. Annual outputs, high yield journals, countries, institutions, authors and their cited times were summarized. In addition, keywords co-occurrence, burst references and citation networks were bibliometric analyzed.From 2000 to 2019, 418 articles were published. Both of the Environment International and Environmental Health Perspectives, United States, Chinese Academy of Sciences and Antonia M. Calafat were the most recorded journals, countries, institutions and authors, respectively. The main research area was Toxicology. In addition of the retrieve term "bisphenol-a" and "thyroid-hormone", "in-vitro", "exposure" and "endocrine disruptors", were the hotspot keywords and "triclosan", "oxidative stress" and "united-states" were the most recent trends keywords. "Thyroid hormone action is disrupted by Bisphenol A as an antagonist" published on The Journal of Clinical Endocrinology & Metabolism by Kenji Moriyama in 2002 got both the highest burst score and citation score. Six groups were clustered and the mechanism of BPA's effect on thyroid hormones, and the exposure of BPA and potential risks in children and pregnant women were the two main large fields.The number of publications in the field of BPA and thyroid hormones has increased tremendously since 2000. The research hotspot ranged from mechanism researches in animal models to epidemiological studies. "Thyroid hormone action is disrupted by bisphenol A as an antagonist" of Kenji Moriyama provided important building blocks in the field. The impact of BPA on thyroid hormones, especially pregnant women and children, was the latest research frontiers and might be the future direction of this filed in the following years.

RESUMO

PURPOSE: To identify the 100 most cited research articles on cervical cancer radiotherapy. METHODS: The Web of Science and Scopus databases were searched to identify the 100 most cited articles on cervical cancer radiotherapy as of September 29, 2019. Articles were ranked based on the total citations received from 2 databases. One hundred articles about radiotherapy for cervical cancer were identified. The following important information was extracted: author, journal, year and month of publication, country or region, and radiotherapy technologies. RESULTS: The 100 most cited articles on cervical cancer radiotherapy were published between 1964 and 2016, and the total citations from 2 databases ranged from 3478 to 211, including a total of 49,262 citations as of September 29, 2019. The index of citations per year ranged from 170.4 to 13.1. These articles were from 16 countries or regions, with most publications being from the United States (n = 38), followed by Austria (n = 15), Canada (n = 8), France (n = 8) and the United Kingdom (n = 7). The International Journal of Radiation Oncology, Biology, Physics produced the most articles (n = 42), followed by Radiotherapy and Oncology (n = 13), Cancer (n = 8) and Journal of Clinical Oncology (n = 7). These articles were categorized as original studies (n = 86), recommendations (n = 5), guidelines (n = 5) and reviews (n = 4). Of the 100 most cited articles, intracavitary brachytherapy (n = 50) and 3-dimensional conformal radiotherapy (n = 34) were the most commonly used treatment techniques. CONCLUSION: To the best of our knowledge, this is the first report and analysis of the most cited articles on cervical cancer radiotherapy. This bibliographic study presents the history of technological development in external radiation therapy and brachytherapy. Brachytherapy is an indispensable part of radiotherapy for cervical cancer. The International Journal of Radiation Oncology Biology Physics is the journal with the most publications related to cervical cancer radiotherapy.

RESUMO

BACKGROUND: Publications regarding the 100 top-cited articles in a given discipline are common, but studies reporting the association between article topics and their citations are lacking. Whether or not reviews and original articles have a higher impact factor than case reports is a point for verification in this study. In addition, article topics that can be used for predicting citations have not been analyzed. Thus, this study aims to METHODS:: We searched PubMed Central and downloaded 100 top-cited abstracts in the journal Medicine (Baltimore) since 2011. Four article types and 7 topic categories (denoted by MeSH terms) were extracted from abstracts. Contributors to these 100 top-cited articles were analyzed. Social network analysis and Sankey diagram analysis were performed to identify influential article types and topic categories. MeSH terms were applied to predict the number of article citations. We then examined the prediction power with the correlation coefficients between MeSH weights and article citations. RESULTS: The citation counts for the 100 articles ranged from 24 to 127, with an average of 39.1 citations. The most frequent article types were journal articles (82%) and comparative studies (10%), and the most frequent topics were epidemiology (48%) and blood and immunology (36%). The most productive countries were the United States (24%) and China (23%). The most cited article (PDID = 27258521) with a count of 135 was written by Dr Shang from Shandong Provincial Hospital Affiliated to Shandong University (China) in 2016. MeSH terms were evident in the prediction power of the number of article citations (correlation coefficients  = 0.49, t = 5.62). CONCLUSION: The breakthrough was made by developing dashboards showing the overall concept of the 100 top-cited articles using the Sankey diagram. MeSH terms can be used for predicting article citations. Analyzing the 100 top-cited articles could help future academic pursuits and applications in other academic disciplines.

RESUMO

BACKGROUND: Individual researchers' achievements (IRA) are determined by both personal publications and article citations such as Author Impact Factor, h-index, and x-index. Due to those indicators not truly supporting a normal distribution, the traditional t-test and Analysis of variance are not allowed for RA comparison in groups. The objective of this study is to use the bootstrapping method to verify whether hospital physicians have different h-indexes. METHODS: We downloaded 63,266 journal articles with their corresponding citations for 2128 researchers from a Taiwan university website on December 10, 2019. Their IRAs were assessed using the bibliometric h-index. A pyramid plot was used to compare the h-index patterns between institutes. The x-index and the Kano model were found to be complemental to the h-index for identifying the group IRA characteristics and rankings, including colleges and departments in the university study, the School of Medicine, and the Affiliated Hospital. The bootstrapping method was applied with an estimated 95% confidence interval (CI) to distinguish the differences in physicians between the Internal Medicine and Surgery departments. The stronger-than-the-next coefficient (SC) for the highest represents the RA strength. RESULTS: The highest h-indices were found in the College of Engineering, School of Medicine, and the Department of Internal Medicine in groups of colleges (SC = 0.71), all departments (SC = 0.83), the School of Medicine (SC = 0.74), and the Affiliated Hospital (SC = 0.56), respectively. No difference in h-index for hospital physicians was found between departments in Internal Medicine (Mean = 2.14, 95% CI = 1.02,3.26) and Surgery (mean = 2.5, 95%CI = 1.48, 3.52). CONCLUSIONS: The x-index and the Kano models can complement the h-index for identifying group IRA characteristics. The bootstrapping method allows estimation of the sampling distribution for almost any statistic using random sampling methods and gains measures of accuracy (as defined by 95% CI). The finding of no difference in h-index for hospital physicians between departments in Internal Medicine and Surgery requires further investigation in the future.

RESUMO

Engagement with scientific manuscripts is frequently facilitated by Twitter and other social media platforms. As such, the demographics of a paper's social media audience provide a wealth of information about how scholarly research is transmitted, consumed, and interpreted by online communities. By paying attention to public perceptions of their publications, scientists can learn whether their research is stimulating positive scholarly and public thought. They can also become aware of potentially negative patterns of interest from groups that misinterpret their work in harmful ways, either willfully or unintentionally, and devise strategies for altering their messaging to mitigate these impacts. In this study, we collected 331,696 Twitter posts referencing 1,800 highly tweeted bioRxiv preprints and leveraged topic modeling to infer the characteristics of various communities engaging with each preprint on Twitter. We agnostically learned the characteristics of these audience sectors from keywords each user's followers provide in their Twitter biographies. We estimate that 96% of the preprints analyzed are dominated by academic audiences on Twitter, suggesting that social media attention does not always correspond to greater public exposure. We further demonstrate how our audience segmentation method can quantify the level of interest from nonspecialist audience sectors such as mental health advocates, dog lovers, video game developers, vegans, bitcoin investors, conspiracy theorists, journalists, religious groups, and political constituencies. Surprisingly, we also found that 10% of the preprints analyzed have sizable (>5%) audience sectors that are associated with right-wing white nationalist communities. Although none of these preprints appear to intentionally espouse any right-wing extremist messages, cases exist in which extremist appropriation comprises more than 50% of the tweets referencing a given preprint. These results present unique opportunities for improving and contextualizing the public discourse surrounding scientific research.

RESUMO

This paper analyzes the impact of air transport connectivity and accessibility on scientific collaboration. Numerous studies demonstrated that the likelihood of collaboration declines with increase in distance between potential collaborators. These works commonly use simple measures of physical distance rather than actual flight capacity and frequency. Our study addresses this limitation by focusing on the relationship between flight availability and the number of scientific co-publications. Furthermore, we distinguish two components of flight availability: (1) direct and indirect air connections between airports; and (2) distance to the nearest airport from cities and towns where authors of scientific articles have their professional affiliations. Based on Zero-inflated Negative Binomial Regression, we provide evidence that greater flight availability is associated with more frequent scientific collaboration. More flight connections (connectivity) and proximity of airport (accessibility) increase the expected number of coauthored scientific papers. Moreover, direct flights and flights with one transfer are more valuable for intensifying scientific cooperation than travels involving more connecting flights. Further, analysis of four organizational sub-datasets-Arizona State University, Indiana University Bloomington, Indiana University-Purdue University Indianapolis, and University of Michigan-shows that the relationship between airline transport availability and scientific collaboration is not uniform, but is associated with the research profile of an institution and the characteristics of the airport that serves this institution.

RESUMO

The success of a scientist depends on their production of scientific papers and the impact factor of the journal in which they publish. Because most major scientific journals are published in English, success is related to publishing in this language. Currently, 98% of publications in science are written in English, including researchers from English as a Foreign Language (EFL) countries. Colombia is among the countries with the lowest English proficiency in the world. Thus, understanding the disadvantages that Colombians face in publishing is crucial to reducing global inequality in science. This paper quantifies the disadvantages that result from the language hegemony in scientific publishing by examining the additional costs that communicating in English creates in the production of articles. It was identified that more than 90% of the scientific articles published by Colombian researchers are in English, and that publishing in a second language creates additional financial costs to Colombian doctoral students and results in problems with reading comprehension, writing ease and time, and anxiety. Rejection or revision of their articles because of the English grammar was reported by 43.5% of the doctoral students, and 33% elected not to attend international conferences and meetings due to the mandatory use of English in oral presentations. Finally, among the translation/editing services reviewed, the cost per article is between one-quarter and one-half of a doctoral monthly salary in Colombia. Of particular note, we identified a positive correlation between English proficiency and higher socioeconomic origin of the researcher. Overall, this study exhibits the negative consequences of hegemony of English that preserves the global gap in science. Although having a common language is important for science communication, generating multilinguistic alternatives would promote diversity while conserving a communication channel. Such an effort should come from different actors and should not fall solely on EFL researchers.

RESUMO

Research on osteoporosis is a well-developed and promising research field. The top 100 literature included 73 articles and 27 reviews. The average citation number was 747 (range 370 to 2970). Researchers and institutions from the USA, the UK, and France contributed the most to the top high-cited articles. PURPOSE: To provide a bibliometric and visualized analysis of the top 100 highly cited articles on osteoporosis indexed by the Web of Science (WoS) from 1990 to 2019. METHODS: Data were obtained from the WoS Core Collection on Jan 10, 2020. Qualitative and quantitative analysis was conducted based on WoS. Collaboration analysis and keywords analysis were performed using VosView software. RESULTS: A total of 12,863 references were obtained. The top 100 highly cited literature included 73 articles and 27 reviews. The average citation number of the 100 articles was 747 (range 370 to 2970). The fund sources mostly came from the USA. A total of 29 journals published the top 100 highly cited literature. The New England Journal of Medicine had the largest number of papers and the highest total cited times. The USA published 72 articles. The University of California San Francisco published 17 articles, followed by University of Sheffield and Mayo Clinic and Mayo Foundation. Cooper C had the most publications (n = 12) and Genant HK had the largest total citation (n = 11,055). Considering only the first author and corresponding author, Kanis JA had published the most articles. Researchers and institutions from the USA, the UK, and France contributed the most to the top high-cited articles. CONCLUSIONS: Research on osteoporosis is a well-developed and promising research field. The top 100 articles have been cited widely and actively. New England Journal of Medicine was the most popular journal. The most productive country was the USA. The University of California San Francisco, University of Sheffield, and Mayo Clinic and Mayo Foundation were the most productive institutions. Cooper C, Kanis JA, and Genant HK were the most prolific and influential authors. Researchers and institutions from North America and Europe contributed the most.

RESUMO

BACKGROUND: The gender disparity between the number of female and male chairs and program directors has been previously established. The aim of this study was to determine whether any differences in objective credentials existed between male and female plastic surgery department chairs/division chiefs and program directors. METHODS: Information about each plastic surgery program director and chair/chief was extracted from the websites of all institutions affiliated with a plastic surgery residency program. For each individual, information about the length of their career, number of fellowships completed, and number of publications was recorded. The two-tailed t test was used to compare differences between male and female chairs and program directors. RESULTS: A total of 99 chairs were recorded, of which nine (9.1 percent) were female. Of the 99 program directors, 13 (13.1 percent) were female. There was no difference in the number of years in practice or number of fellowships between men and women for either position. On average, male chairs had significantly fewer publications than female chairs (71.9 versus 128; p < 0.05). There was no significant difference in the number of publications between male and female program directors. Compared to program directors, chairs had significantly more years in practice and numbers of publications, which held true for both men and women. CONCLUSIONS: Women are not only underrepresented in the department chair and program director positions, but also possess higher qualifications that may reflect differences in standards for promotion and appointment. Additional research is needed to elucidate the reasons behind the observed differences in qualifications.

RESUMO

Sudden infant death syndrome (SIDS) is a poorly understood disorder, and its pathophysiology and risk factors remain unclear. Research in the area is the key to combating the pervasive prevalence of this fatal disorder. We sought to identify the top 50 articles concerning SIDS and study their bibliometric characteristics to gain an insight into the research trends in this area. Using the Scopus database, two independent reviewers conducted a literature search using a prespecified search string. Results were arranged according to the citation count, and the top 50 relevant articles were selected. No time restrictions were set, and all types of articles were included. A detailed analysis was carried out to identify the trends and characteristics of the top 50 articles. The top 50 articles were published between 1972 and 2011, with the most productive 5-year interval being 1991-1995. These 50 papers accumulated a total of 13,703 citations (median = 236 citations per paper). Among these, about 9% were self-citations. The citations received by these core papers seemed to decline post-2009. The top 50 articles were published in 21 different journals, with Pediatrics contributing the most (n = 15). US authors were listed for 60% of the articles (n = 30). None of the articles originated from Asian authors. Our manuscript highlights the characteristics of impactful articles on SIDS - and this can act as a directive for researchers aiming to publish on this topic. Bibliometric parameters suggest a decreasing research interest in the fi eld of SIDS, which is concerning, and efforts should be made to promote research. Furthermore, the lack of influential research from Asian authors is also troubling. Funding should preferably be directed toward Asian researchers to bridge the gap in knowledge.

RESUMO

A citation study of a sample of earth science projects in citizen science from the FedCats Catalog was undertaken to assess whether citizen science projects are as productive and as impactful as conventional research that does not employ volunteer participation as a part of their data gathering and analysis protocols. From the 783 peer-reviewed papers produced by 48 projects identified from project bibliographies, 12,380 citations were identified using the Web of Science archive and their citation search engine to the end of 2018. Various conventional productivity and impact measures were applied including the Impact Factor, H and M-indices, and entry into the Top-1000 papers in cited research. The earth science projects tend to under-perform in terms of Impact Factor (IF = 14-20) and the M-index (M<0.5) but perform at the level of a 'tenured professor' with = 23. When compared to non-citizen science research in general, there is a ten-fold higher probability of the earth science papers reaching the Top-1000 threshold of most-cited papers in natural science research. Some of the reasons for the lower performance by some indicators may have to do with the down-turn in published papers after 2010 for the majority of the earth science projects, which itself could be related to the fact that 52% of these projects only became operational after 2010 compared to the more successful 'Top-3' projects, whose impacts resemble the general population of non-citizen science research.

RESUMO

Here we present the results of a bibliometric survey of peer-reviewed and pre-print papers published in the English language on issues related to COVID-19 within the first three months since a cluster of a severe acute respiratory disease of unknown etiology was officially confirmed by the Chinese Center for Disease Control and Prevention on 31 December 2019. A systematic search using PubMed/Medline and Scopus databases and preprint servers was performed. The articles were classified according to their type, subject and country of origin. Up to 31 March 2020, a total of 2062 papers published in 578 peer-reviewed journals and 1425 preprints posted mostly on medRxiv (55.4 %), were identified. The mean number of published journal papers and preprints per day in the considered period was 27 and 12, respectively, and reached a maximum of 51 and 46 per day in March, respectively. The identified articles, journal papers and preprints, mostly covered the epidemiology of COVID-19 (35.7 %), clinical aspects of infection (21.0 %), preventative measures (12.8 %), treatment options (12.5 %), diagnostics (12.2 %), mathematical modeling of disease transmission and mitigation (9.6 %), and molecular biology and pathogenesis of SARS-CoV-2 (8.7 %). The majority of the journal papers were commentaries (38.5 %), reviews (33.6 %) and original research (21.3 %), while preprints predominantly presented original results (89.8 %). Chinese scientists contributed the highest share of original research and were responsible for 32.9 % journal papers and 43.9 % preprints published in the considered period. A high number of contributions was also seen from the United States, the United Kingdom, and Italy. The benefits and potential risks of such a massive publication output are discussed. The scientific response seen during the first 3 months of the COVID-19 outbreak is a demonstration of the capabilities of modern science to react rapidly to emerging global health threats by providing and discussing the essential information for understanding the etiological factor, its spread, preventative measures, and mitigation strategies.

RESUMO

BACKGROUND: The evolving landscape of academic surgery demands leaders who are not only effective clinicians and researchers, but also administrators able to navigate complex hospital organizations, financial pressures in the era of quality measures, and inclusion of an increasingly diverse workforce. The aim of this study was to characterize achievements and assess perspectives in becoming a surgical chair in order to guide young surgeons in their career trajectories to surgical leadership. METHODS: A survey encompassing demographics, surgical training, nonmedical advanced degrees, academic advancement, and leadership experiences was sent via electronic mail to members of the American College of Surgeons Society of Surgical Chairs in December 2018. RESULTS: Of 191 Society of Surgical Chairs members, 52 (27.2%) completed the survey, with 6 (11.5%) women, 40 (76.9%) white, and the majority becoming chair between ages 46 and 60 (n = 39, 75.0%). Training beyond residency included fellowships (n = 41, 78.8%) and advanced nonmedical degrees (n = 15, 28.8%). Median H-index was 47 (range 10-120) with 126 (5-500) research publications, and grants received was 2 (0-38) for federal and 5 (0-43) for industry. Female chairs appear to have fewer nonmedical degrees (n = 1) and no difference in age at becoming chair (66.7% vs 79.6% between ages 46 and 60), H-index (26 [10-41] vs 49 [17-120]), or publications (93 [10-189] vs 150 [5,500]). Prior educational (n = 36, 69.2%) and clinical (n = 44, 84.6%) leadership roles were common, with 30 chairs (57.7%) having held both roles. Experiences which respondents felt have most helped them function as chair included serving as a clinical division director (n = 37, 71.2%), residency program director (n = 28, 53.8%), leadership courses (n = 28, 53.8%), a research career (n = 22, 42.3%), and being a vice/interim chair (n = 15, 28.8%). Personal traits felt to be most important in becoming a successful chair included being effective at communication (n = 37, 71.2%), collaborative (n = 35, 67.3%), trustworthy (n = 30, 57.7%), and a problem-solver (n = 27, 51.9%). CONCLUSION: Becoming a department surgical chair often involves not only surgical subspecialty expertise, but also nonmedical training and prior leadership roles, which help facilitate development of skills integral to navigating the collaborative and diverse nature of academic surgery in the current era.

RESUMO

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic constitutes an ongoing, burning Public Health Emergency of International Concern (PHEIC). In 2015, the World Health Organization adopted an open data policy recommendation in such situations. OBJECTIVES: The present cross-sectional meta-research study aimed to assess the availability of open data and metrics of articles pertaining to the COVID-19 outbreak in five high-impact journals. METHODS: All articles regarding the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), published in five high-impact journals (Ann Intern Med, BMJ, JAMA, NEJM and Lancet) until March 14, 2020 were retrieved. Metadata (namely the type of article, number of authors, number of patients, citations, errata, news and social media mentions) were extracted for each article in each journal in a systematic way. Google Scholar and Scopus were used for citations and author metrics respectively, and Altmetrics and PlumX were used for news and social media mentions retrieval. The degree of adherence to the PHEIC open data call was also evaluated. RESULTS: A total of 140 articles were published until March 14, 2020, mostly opinion papers. Sixteen errata followed these publications. The number of authors in each article ranged from 1 to 63, whereas the number of patients with a laboratory-confirmed SARS-CoV-2 infection reached 2645. Extensive hyperauthorship was evident among case studies. The impact of these publications reached a total of 4210 cumulative crude citations and 342 790 news and social media mentions. Only one publication (0.7%) provided complete open data, while 32 (22.9%) included patient data. CONCLUSIONS: Even though a large number of manuscripts was produced since the pandemic, availability of open data remains restricted.
