RESUMO

OBJECTIVE: Concerns have been raised that the COVID-19 pandemic has shifted research productivity to the disadvantage of women in academia, particularly in early career stages. In this study, we aimed to assess the pandemic's effect on women's COVID-19-related publishing over the first year of the pandemic. METHODS AND RESULTS: We compared the gender distribution of first authorships for 42 898 publications on COVID-19 from 1 February 2020 to 31 January 2021 to 483 232 publications appearing in the same journals during the same period the year prior. We found that the gender gap-the percentage of articles on which men versus women were first authors-widened by 14 percentage points during the COVID-19 pandemic, despite many pertinent research fields showing near equal proportions of men and women first authors publishing in the same fields before the pandemic. Longitudinal analyses revealed that the significant initial expansions of the gender gap began to trend backwards to expected values over time in many fields. As women may have been differentially affected depending on their geography, we also assessed the gender distribution of first authorships grouped by countries and geographical areas. While we observed a significant reduction of the shares of women first authors in almost all countries, longitudinal analyses confirmed a resolving trend over time. CONCLUSION: The reduction in women's COVID-19-related research output appears particularly concerning as many disciplines informing the response to the pandemic had near equal gender shares of first authorship in the year prior to the pandemic. The acute productivity drain with the onset of the pandemic magnifies deep-rooted obstacles on the way to gender equity in scientific contribution.

RESUMO

BACKGROUND: Outbreaks of infectious diseases generate outbreaks of scientific evidence. In 2016 epidemics of Zika virus emerged, and in 2020, a novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) caused a pandemic of coronavirus disease 2019 (COVID-19). We compared patterns of scientific publications for the two infections to analyse the evolution of the evidence. METHODS: We annotated publications on Zika virus and SARS-CoV-2 that we collected using living evidence databases according to study design. We used descriptive statistics to categorise and compare study designs over time. RESULTS: We found 2286 publications about Zika virus in 2016 and 21,990 about SARS-CoV-2 up to 24 May 2020, of which we analysed a random sample of 5294 (24%). For both infections, there were more epidemiological than laboratory science studies. Amongst epidemiological studies for both infections, case reports, case series and cross-sectional studies emerged first, cohort and case-control studies were published later. Trials were the last to emerge. The number of preprints was much higher for SARS-CoV-2 than for Zika virus. CONCLUSIONS: Similarities in the overall pattern of publications might be generalizable, whereas differences are compatible with differences in the characteristics of a disease. Understanding how evidence accumulates during disease outbreaks helps us understand which types of public health questions we can answer and when.

RESUMO

BACKGROUND: With the evolving specialization of modern medicine, family medicine (FM), also known as general practice, is relatively late in being recognized as a formal specialty in most countries of the world. Because many non-FM specialists were recruited into the new specialty in the early stages of FM specialization, the contents of FM specialty journals might, to an extent, reflect the development of the FM specialization. METHODS: In this study, the voluminous journal, Chinese General Practice, which is regarded as the most representative specialty journal, was chosen and analyzed to illustrate the current situation of FM in China. A total of 878 articles, relating to the journal, Chinese General Practice in 2018, were retrieved from the publisher's web site and the original articles were categorized into FM- and non-FM- related articles by 3 board-certified FM doctors. Furthermore, the first authors, as well as the institutions and regions where the first authors worked, and their related specialties, were also analyzed. RESULTS: Of the 634 original articles, 252 (39.7%) articles were FM related. Only 41 FM-related articles were written by authors working at FM departments: 3 at community health service centers, 29 at hospitals, and 9 at universities. Of the 382 non-FM related articles, 159 articles dealt with the topic of internal medicine, followed by traditional Chinese medicine (36), obstetrics and gynecology (28), neurology (27), pediatrics (27), and surgery (21). CONCLUSION: In conclusion, FM publications in China in the study year, as exemplified by Chinese General Practice, were mostly contributed by non-FM authors dealing with non-FM topics. A transition to more FM-oriented development might be anticipated in the near future.

RESUMO

BACKGROUND: The COVID-19 pandemic increased the gender gap in academic publishing. This study assesses COVID-19's impact on ophthalmology gender authorship distribution and compares the gender authorship proportion of COVID-19 ophthalmology-related articles to previous ophthalmology articles. METHODS: This cohort study includes authors listed in all publications related to ophthalmology in the COVID-19 Open Research Dataset and CDC COVID-19 research database. Articles from 65 ophthalmology journals from January to July 2020 were selected. All previous articles published in the same journals were extracted from PubMed. Gender-API determined authors' gender. RESULTS: Out of 119,457 COVID-19-related articles, we analyzed 528 ophthalmology-related articles written by 2518 authors. Women did not exceed 40% in any authorship positions and were most likely to be middle, first, and finally, last authors. The proportions of women in all authorship positions from the 2020 COVID-19 group (29.6% first, 31.5% middle, 22.1% last) are significantly lower compared to the predicted 2020 data points (37.4% first, 37.0% middle, 27.6% last) (p < .01). The gap between the proportion of female authors in COVID-19 ophthalmology research and the 2020 ophthalmology-predicted proportion (based on 2002-2019 data) is 6.1% for overall authors, 7.8% for first authors, and 5.5% for last and middle authors. The 2020 COVID-19 authorship group (1925 authors) was also compared to the 2019 group (33,049 authors) based on journal category (clinical/basic science research, general/subspecialty ophthalmology, journal impact factor). CONCLUSIONS: COVID-19 amplified the authorship gender gap in ophthalmology. When compared to previous years, there was a greater decrease in women's than men's academic productivity.

RESUMO

INTRODUCTION: Numerous scientific journal articles related to COVID-19 have been rapidly published, making navigation and understanding of relationships difficult. METHODS: A graph network was constructed from the publicly available COVID-19 Open Research Dataset (CORD-19) of COVID-19-related publications using an engine leveraging medical knowledge bases to identify discrete medical concepts and an open-source tool (Gephi) to visualise the network. RESULTS: The network shows connections between diseases, medications and procedures identified from the title and abstract of 195 958 COVID-19-related publications (CORD-19 Dataset). Connections between terms with few publications, those unconnected to the main network and those irrelevant were not displayed. Nodes were coloured by knowledge base and the size of the node related to the number of publications containing the term. The data set and visualisations were made publicly accessible via a webtool. CONCLUSION: Knowledge management approaches (text mining and graph networks) can effectively allow rapid navigation and exploration of entity inter-relationships to improve understanding of diseases such as COVID-19.

RESUMO

ABSTRACT: The independent plastic surgery pathway recruits candidates with 5 years of surgical training who are typically more advanced in research than their integrated counterparts. Research productivity helps to discriminate between applicants. However, no studies exist detailing the academic attributes of matched independent plastic surgery candidates.We performed a cohort study of 161 independent plastic surgery fellows from accredited residency programs from the 2015 to 2017 application cycles. We performed a bibliometric analysis utilizing Scopus, PubMed, and Google Scholar to identify research output measures at the time of application.The cohort was predominantly men (66%) with a median of 3 articles and a H-index of 1 at the time of application. Interestingly, 16% of successful candidates had no published articles at the time of application, and this did not change significantly over time (P = .0740). Although the H-index remained stable (R 0.13, P = .1095), the number of published journal articles per candidate significantly decreased over 3 consecutive application cycles (R -0.16, P = .0484). Analysis of article types demonstrated a significant increase in basic science articles (R 0.18, P = .0366) and a concurrent decrease in editorial-type publications (R = -0.18, P = .0374).Despite the decline in publication volume of matched independent plastic surgery fellows, the quality of their research portfolio has remained constant. Matched applicants appear to be shifting focus from faster-to-publish articles to longer but higher impact projects. In selecting a training route, applicants must weigh the highly competitive integrated path against the dwindling number of independent positions.

RESUMO

INTRODUCTION: Both the COVID-19 pandemic and its management have had a negative impact on mental health worldwide. There is a growing body of research on mental health as it relates to the pandemic. The objective of this study is to use bibliometric analyses to assess the mental health research output related to the COVID-19 pandemic and compare it to that of the West Africa Ebola and H1N1 outbreaks. METHODOLOGY: We performed comprehensive searches in Embase, PubMed, and Scopus databases, and included all types of documents related to the three outbreaks published since the respective beginnings up to August 26, 2020. RESULTS: Despite the shorter time since the beginning of the COVID-19 pandemic, relative to Ebola and H1N1, we found a much greater number of mental health documents related to COVID-19 (n = 3070) compared to the two other outbreaks (127 for Ebola and 327 for H1N1). The proportion of documents in the top 10% journals was 31% for COVID-19, 24% for Ebola, and 40% for H1N1. Authors affiliated with institutions located in high-income countries published or contributed to 79% of all documents followed by authors from upper-middle-income countries (23%), lower-middle-income countries (10%), and low-income countries (2%). Approximately 19% of the documents reported receiving funding and 23% were the product of international collaboration. CONCLUSION: Mental health research output is already greater for COVID-19 compared to Ebola and H1N1 combined. A minority of documents reported funding, was the product of international collaboration, or was published by authors located in low-income countries during the three outbreaks in general, and the COVID-19 pandemic in particular.

RESUMO

OBJECTIVES: In this study, we aimed to provide bibliometric and Altmetric overviews and visualization and to evaluate the correlation between traditional bibliometric and Altmetric analyses in the field of malnutrition. METHODS: Articles published in the past decade were identified by searching for the term "malnutrition" on the Web of Science indexing database and research platform. The top 50 cited articles were analyzed in terms of title, study type, topic of study, first author, publication year, citation number, keywords, organizations, average citations per year, journal H index, impact factor, and Altmetric attention score. Also, the top 50 Altmetric articles published in the past decade about malnutrition were provided on the website Altmetric.com. RESULTS: Among the top 50 cited articles, the most common study type, topic of study, publication year, and keyword were, respectively, original scientific paper (n = 26), definition-diagnosis of malnutrition (n = 17), 2010 (n = 13), and malnutrition (n = 18). The article titled "Maternal and child undernutrition and overweight in low-income and middle-income countries" in Lancet had the highest citation number, and the article "Impacts of COVID-19 on childhood malnutrition and nutrition-related mortality" in Lancet had the highest Altmetric score. CONCLUSIONS: Evaluating academic publications with an Altmeric analysis in addition to a traditional bibliometric analysis is beneficial because Altmetric attention scores can give information about what the population wants to know about malnutrition and allows us to develop appropriate policies.

RESUMO

As this extraordinary year, blemished by COVID-19, comes to an end, I look back as Editor-in-Chief to the many great successes and new initiatives of Clinical Science. Despite the challenges we all faced during 2020, our journal has remained strong and vibrant. While we have all adapted to new working conditions, with life very different to what it was pre-COVID-19, the one thing that remains intact and secure is the communication of scientific discoveries through peer-reviewed journals. I am delighted to share with you some of the many achievements of our journal over the past year and to highlight some exciting new activities planned for 2021.

RESUMO

INTRODUCTION: There is emerging evidence that food industry involvement in nutrition research may bias research findings and/or research agendas. However, the extent of food industry involvement in nutrition research has not been systematically explored. This study aimed to identify the extent of food industry involvement in peer-reviewed articles from a sample of leading nutrition-related journals, and to examine the extent to which findings from research involving the food industry support industry interests. METHODS: All original research articles published in 2018 in the top 10 most-cited nutrition- and dietetics-related journals were analysed. We evaluated the proportion of articles that disclosed involvement from the food industry, including through author affiliations, funding sources, declarations of interest or other acknowledgments. Principal research findings from articles with food industry involvement, and a random sample of articles without food industry involvement, were categorised according to the extent to which they supported relevant food industry interests. RESULTS: 196/1,461 (13.4%) articles reported food industry involvement. The extent of food industry involvement varied by journal, with The Journal of Nutrition (28.3%) having the highest and Paediatric Obesity (3.8%) having the lowest proportion of industry involvement. Processed food manufacturers were involved in the most articles (77/196, 39.3%). Of articles with food industry involvement, 55.6% reported findings favourable to relevant food industry interests, compared to 9.7% of articles without food industry involvement. CONCLUSION: Food industry involvement in peer-reviewed research in leading nutrition-related journals is commonplace. In line with previous literature, this study has shown that a greater proportion of peer-reviewed studies involving the food industry have results that favour relevant food industry interests than peer-reviewed studies without food industry involvement. Given the potential competing interests of the food industry, it is important to explore mechanisms that can safeguard the integrity and public relevance of nutrition research.

RESUMO

Introduction: The propagation of COVID-19, an infectious disease caused by the novel SARS-CoV-2 coronavirus, has become a pandemic which, along with its rapid dissemination worldwide, has brought about an exponential increase in the amount of research related to the subject to which Latin American researchers have contributed actively. Objective: To conduct a descriptive bibliometric study of the main trends in research on COVID-19 produced in Latin America. Materials and methods: We searched in the Web of Science, Scopus, and Pubmed databases to retrieve the Latin American scientific production on COVID-19. Bibliometric indicators of production, visibility, impact, and collaboration were analyzed to assess the regional participation in studies on the subject. Results: The analysis of 142 documents evidenced an exponential growth of scientific production in the period analyzed, an important level of international collaboration (51.4%) in scientific production, and the leadership of regional institutions (71%) in the research with publications in high-visibility jounals especially in Colombia, Brazil, and México. Conclusions: The results regarding the regional participation in the research on COVID-19 were relevant not only in relation to its quantity and exponential growth during the period analyzed but also in terms of its quality and excellence with a high rate of international collaboration and publications in important scientific journals, which besides their visibility, represent a considerable contribution to the research compared to the other geographical contexts.

RESUMO

Scientific claims in biomedical research are typically derived from statistical analyses. However, misuse or misunderstanding of statistical procedures and results permeate the biomedical literature, affecting the validity of those claims. One approach journals have taken to address this issue is to enlist expert statistical reviewers. How many journals do this, how statistical review is incorporated, and how its value is perceived by editors is of interest. Here we report an expanded version of a survey conducted more than 20 years ago by Goodman and colleagues (1998) with the intention of characterizing contemporary statistical review policies at leading biomedical journals. We received eligible responses from 107 of 364 (28%) journals surveyed, across 57 fields, mostly from editors in chief. 34% (36/107) rarely or never use specialized statistical review, 34% (36/107) used it for 10-50% of their articles and 23% used it for all articles. These numbers have changed little since 1998 in spite of dramatically increased concern about research validity. The vast majority of editors regarded statistical review as having substantial incremental value beyond regular peer review and expressed comparatively little concern about the potential increase in reviewing time, cost, and difficulty identifying suitable statistical reviewers. Improved statistical education of researchers and different ways of employing statistical expertise are needed. Several proposals are discussed.
