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

[RESUMEN]. Objetivo. Medir a través del análisis bibliométrico la productividad, la visibilidad y el impacto del Sistema Regional de Vacunas (SIREVA, un proyecto de la Organización Panamericana de la Salud) en sus dos componentes, la vigilancia por laboratorio y el desarrollo de vacunas. Métodos. Se recuperaron de Scopus las publicaciones correspondientes a vigilancia por laboratorio y desarrollo de vacunas con sus referencias y citas y se aplicó la herramienta para obtener los indicadores bibliométricos. Se utilizó VOSviewer® 1.6.13 para visualizar las redes de coautoría por país y autores, y para realizar un análisis de coocurrencia de términos incluidos en los títulos y resúmenes de las publicaciones. Resultados. Cumplieron los criterios establecidos para vigilancia por laboratorio y desarrollo de vacunas 173 y 128 publicaciones, respectivamente. Diez países de la Región fueron responsables de 90,8% de las publicaciones sobre vigilancia por laboratorio y 8 países de todas las publicaciones sobre desarrollo de vacunas. Las diez publicaciones más citadas sobre vigilancia por laboratorio y sobre desarrollo de vacunas estaban incluidas en 855 y 503 artículos, respectivamente; los principales autores se encontraban en Alemania, Australia, Bélgica, Brasil, China, Estados Unidos de América y el Reino Unido. La construcción y visualización de redes por coautorías de autores y países, y la coocurrencia de términos mostraron el trabajo en red y la colaboración intrarregional, así como permitieron hacer seguimiento a las diversas áreas de estudio y su evolución en el tiempo. Conclusiones. El análisis bibliométrico permitió documentar de manera objetiva la productividad y visibilidad del Sistema Regional de Vacunas para Streptococcus pneumoniae en la Región.


[ABSTRACT]. Objective. To measure through bibliometric analysis the productivity, visibility and impact of the Regional for Vaccines (SIREVA, a project by the Pan American Health Organization), including its two components laboratory surveillance and vaccine development. Methods. Publications about laboratory surveillance and vaccine development were recovered from Scopus, including their references and citations, and their bibliometric indicators were analyzed. VOSviewer 1.6.13® was used to visualize the co-authorship networks, by country and authors, and to perform a cooccurrence analysis of terms included in the titles and abstracts of the publications. Results. The criteria for laboratory surveillance and vaccine development were met by 173 and 128 publications, respectively. Ten countries in the Region of the Americas were responsible for 90.8% of the publications on laboratory surveillance and 8 for all publications on vaccine development. The 10 most cited publications on laboratory surveillance and on vaccine development were included in 855 and 503 articles, respectively, the main authors being from Australia, Belgium, Brazil, China, Germany, the United Kingdom and the United States of America. Network building and visualization by author and country co-authors, and co-occurrence of terms showed networking and intraregional collaboration, and allowed for the follow-up of study areas and evolution over time. Conclusions. The bibliometric analysis allowed to objectively record the productivity and visibility of the Regional System for Vaccines for Streptococcus pneumoniae in the Region.

RESUMO

BACKGROUND: New emerging infections have no known treatment. Assessing potential drugs for safety and efficacy enables clinicians to make evidence-based treatment decisions and contributes to overall outbreak control. However, it is difficult to launch clinical trials in the unpredictable environment of an outbreak. We conducted a bibliometric systematic review for the 2009 influenza pandemic to determine the speed and quality of evidence generation for treatments. This informs approaches to high-quality evidence generation in this and future pandemics. METHODS: We searched PubMed for all clinical data (including clinical trial, observational and case series) describing treatment for patients with influenza A(H1N1)pdm09 and ClinicalTrials.gov for research that aimed to enrol patients with the disease. RESULTS: Thirty-three thousand eight hundred sixty-nine treatment courses for patients hospitalised with A(H1N1)pdm09 were detailed in 160 publications. Most were retrospective observational studies or case series. Five hundred ninety-two patients received treatment (or placebo) as participants in a registered interventional clinical trial with results publicly available. None of these registered trial results was available during the timeframe of the pandemic, and the median date of publication was 213 days after the Public Health Emergency of International Concern ended. CONCLUSION: Patients were frequently treated for pandemic influenza with drugs not registered for this indication, but rarely under circumstances of high-quality data capture. The result was a reliance on use under compassionate circumstances, resulting in continued uncertainty regarding the potential benefits and harms of anti-viral treatment. Rapid scaling of clinical trials is critical for generating a quality evidence base during pandemics.

RESUMO

Rapid development is undergoing in the field of rehabilitation robots, and more countries (regions) are participating in international cooperation and becoming academic contributors. Here in this study, the bibliometric method is used to determine the dynamics and developments of international cooperation in China. The publication data are indexed in Web of Science with search term of rehabilitation robot from 2000 to 2019. Compared with other countries (regions), publication with international co-authors and institutes participating in international cooperation are studied by assessment of indicators such as the cooperation degree, cooperation frequency, and the frequency of citations. The results show that in the past two decades, international scientific cooperation has shown a positive tendency in China, and participating in international collaboration could improve China's impact on the global rehabilitation robot. The United States, England and Japan are the top three countries in number of cooperation with China. Our findings provide valuable information for researchers to better understand China's international scientific collaboration in rehabilitation robot.

RESUMO

BACKGROUND: COVID-19 is the most rapidly expanding coronavirus outbreak in the past 2 decades. To provide a swift response to a novel outbreak, prior knowledge from similar outbreaks is essential. RESULTS: Here, we study the volume of research conducted on previous coronavirus outbreaks, specifically SARS and MERS, relative to other infectious diseases by analyzing >35 million articles from the past 20 years. Our results demonstrate that previous coronavirus outbreaks have been understudied compared with other viruses. We also show that the research volume of emerging infectious diseases is very high after an outbreak and decreases drastically upon the containment of the disease. This can yield inadequate research and limited investment in gaining a full understanding of novel coronavirus management and prevention. CONCLUSIONS: Independent of the outcome of the current COVID-19 outbreak, we believe that measures should be taken to encourage sustained research in the field.

RESUMO

BACKGROUND: Income is 1 of the socio-economic indicators and could directly influence the health outcomes of cardiovascular disease (CVD). The relationship between income and CVD has attracted more and more scholars' attention in the past 20 years. METHODS: To study the current research dynamics of this field, a bibliometric analysis was conducted to evaluate the publications from 1990 to 2018 based on the Science Citation Index Expanded database. By using the Derwent Date Analyzer software, the following aspects were explored: RESULTS:: The USA ranked first in this field, followed by UK and Canada in terms of number of publications. As for institutions, Harvard University took the leading place in the number of publications, as well as the h-index. Plos One had the most publications and "health" was the most frequent used keyword. The leading research area was "public environmental occupational health". CONCLUSIONS: In conclusion, the elderly, the children and the puerpera were the main study population in this field and "disease prevention" was the main study direction. The most concerned health issues in this field were "obesity" and "diet". There might be a lack of articles that explore the associations between income and CVD with a global perspective. Articles on this content are urgently warranted.

RESUMO

OBJECTIVE: To explored the progress of intensive care unit (ICU) delirium between 2010 and 2020 based on knowledge visualization analysis. METHODS: The literatures related to ICU delirium included in Web of Sciences (WOS) and China National Knowledge Infrastructure (CNKI) databases from 2010 to 2020 were collected. A bibliometric analysis was performed. The growth trend was showed by Excel 2019 software. The information about country, institution and author were extracted by VOSviewer 1.6.15 for generating cooperative network, to find the main research power and each cooperative relation. At the same time, Citespace 5.0.R1 was used to analyze those high frequency keywords and bursting keywords and build the map of co-citation reference, in order to explore the evolution of research in the field of ICU delirium and the hotspots about this field in recent 10 years. RESULTS: A total of 1 102 Chinese journal articles and 2 422 English "Articles" or "Reviews" from 2010 to 2020 were collected preliminarily, and the number of published literatures increased steadily. In the respect of quality, the impact factors of most articles were concentrated between 2 and 3, and the literatures with impact factor over 5 accounted for 27.9% (337/1 209). According to the knowledge visualization analysis, the United States published most of the related articles (total 1 152) in this field, while the England and Canada ranked second and third respectively, totaling 220 and 204. In terms of the distribution of research institutions, the Vanderbilt University School of Medicine was not only far ahead in the number of publication (n = 149), but more importantly, top three high-impact authors located in this institution. The amount of domestic publications was lower than developed countries, however, the burst index, which reflected the sudden increase, ranked first (7.09), suggesting that the interest and investment of Chinese researchers was increasing recently. The most productive institution in China was Capital Medical University School of Nursing with totaling 23 articles. Wu Ying, who published most Chinese papers (n = 14), belongs to this institution. However, it was a pity that there was no large scientific community be constructed in China, and the cooperation between institutions was deficient. By generating the co-occuring keyword mapping, the research hotpots mainly focused on the prevention, treatment and prevention of delirium in mechanically ventilated patients, the effect of dexmedetomidine and exploring the risk factor of ICU delirium. Finally, the results of co-citation reference analysis showed that Cluster 4 (risk assessment) was still in the process of development, in hence it was the frontier in this domain. CONCLUSIONS: There was a big gap between China and leading countries in the field of ICU delirium research. The main research power was located in the United States, and the trending of future studies mainly focus on delirium-related risk assessment.

RESUMO

Global health, conceived as a discipline, aims to train, research and respond to problems of a transboundary nature in order to improve health and health equity at the global level. The current worldwide situation is ruled by globalization, and therefore the concept of global health involves not only health-related issues but also those related to the environment and climate change. Therefore, in this Special Issue, the problems related to global health have been addressed from a bibliometric approach in four main areas: environmental issues, diseases, health, education and society.

RESUMO

The alleviation of suffering has always been central to the care of the sick. Yet as medical technology has advanced and life-sustaining treatments multiplied, medicine's capacity to both prevent and create suffering has grown exponentially. In pediatric medicine, the ability to stave off death with life-sustaining treatments allows children to survive but also to suffer in ways that are diverse and unprecedented. However, although parents and pediatric clinicians broadly agree that all children can suffer, there is little published literature in which researchers analyze or clarify the concept of pediatric suffering. This gap is worrisome, especially in light of growing concerns that the label of suffering is used to justify end-of-life decision-making and mask quality-of-life determinations for pediatric patients with profound neurologic impairment. Moreover, the awareness that some children can experience suffering but cannot communicate whether and how they are suffering creates a problem. Does the determination of suffering in a nonverbal child lie in the judgement of clinicians or parents? In this article, I will address several important questions related to the suffering of children through an analysis of two prevalent conceptualizations of pediatric suffering and suggest a possible avenue forward for future scholarship.

RESUMO

BACKGROUND: The novel coronavirus, named as 2019-nCoV or coronavirus disease 2019 (COVID-19), has recently appeared in China and has spread worldwide, presenting a health threat to the global community. Therefore, it is important to understand the global scientific output of COVID-19 research during the early stage of the outbreak. Thus, to track the current hotspots, and highlight future directions, we performed a bibliometric analysis to obtain an approximate scenario of COVID-19 to date. METHODS: Relevant studies to COVID-19 were obtained from the Scopus database during the early stage of the outbreak. We then analysed the data by using well-established bibliometric indices: document type, country, collaboration patterns, affiliation, journal name, and citation patterns. VOSviewer was applied to map and determine hot topics in this field. RESULTS: The bibliometric analysis indicated that there were 19,044 publications on Scopus published on COVID-19 during the early stage of the outbreak (December 2019 up until June 19, 2020). Of all these publications, 9140 (48.0%) were articles; 4192 (22.0%) were letters; 1797 (9.4%) were reviews; 1754 (9.2%) were editorials; 1728 (9.1%) were notes; and 433 (2.3%) were others. The USA published the largest number of publications on COVID-19 (4479; 23.4%), followed by China (3310; 17.4%), Italy, (2314; 12.2%), and the UK (1981; 10.4%). British Medical Journal was the most productive. The Huazhong University of Science and Technology, Tongji Medical, and Harvard Medical School were the institutions that published the largest number of COVID-19 research. The most prevalent topics of research in COVID-19 include "clinical features studies", "pathological findings and therapeutic design", "care facilities preparation and infection control", and "maternal, perinatal and neonatal outcomes". CONCLUSIONS: This bibliometric study may reflect rapidly emerging topics on COVID-19 research, where substantial research activity has already begun extensively during the early stage of the outbreak. The findings reported here shed new light on the major progress in the near future for hot topics on COVID-19 research including clinical features studies, pathological findings and therapeutic design, care facilities preparation and infection control, and maternal, perinatal and neonatal outcomes.

RESUMO

This paper presents the research landscape on microplastics and nanoplastics (M/NPs) in global food webs based on a bibliometric analysis of 330 publications published in 2009-2019 extracted from Web of Science. The publications increased tremendously since 2013. Marine Pollution Bulletin is one of the top productive journals for this topic. The publication landscape related to M/NPs in global food webs, as interdisciplinary research, is highly dependent on the funding availability. The high productivities of England, China, USA and European countries are attributed to the funding from the agencies at regional or national levels. Keyword analysis reveals the shift of research hotspots from investigations on M/NPs absorbed by various organisms in the ecosystems to studies on the trophic transfer of M/NPs and sorbed contaminants in the food webs and their associated adverse impacts. Funding agencies play important roles in leading the future development of this topic.

RESUMO

Este estudo analisou a bibliografia relacionada à hanseníase no Brasil, representada pela publicação de artigos científicos indexados na base de dados científica Web of Science, de 2000 a 2019. Por meio de análise bibliométrica, procurou-se delinear um panorama das produções científicas acerca do tema, identificando os autores, a evolução histórica do número de produções, as áreas de pesquisa que mais publicam, os tipos de artigos publicados e quais as agências financiadoras envolvidas nas publicações relacionadas ao tema. O corpus documental contou com 376 artigos completos, que demonstraram uma intensificação na produção de estudos sobre a hanseníase nos últimos anos, especialmente na área de Medicina Tropical, com predomínio de financiamento por agências brasileiras, e cuja maior fonte de publicações é uma revista científica internacional, dedicada ao estudo de doenças tropicais negligenciadas. Conclui-se que o interesse no estudo do tema se eleva com o passar dos anos, mas dentre as temáticas evidenciadas pela análise empreendida, as políticas públicas para controle e eliminação da doença, foram incipientes. Revela ainda a necessidade de maior aporte científico sobre a temática estimuladas por órgãos governamentais e que amplie as produções científicas por instituições de ensino e pesquisa, que possam alavancar reflexões direcionadas à implementação de diretrizes políticas efetivas para o controle e eliminação da doença.


This study analyzed the literature related to leprosy in Brazil, represented by the publication of scientific papers indexed in the Web of Science scientific database from 2000 to 2019. Through bibliometric analysis, the authors sought to delineate an overview of scientific productions on the topic, identifying the authors, the historical evolution of the number of productions, the areas of research that had most publications, the types of articles published and which funding agencies are involved in publications related to the topic. The documentary corpus consisted of 376 complete articles, which demonstrated an intensification in the production of studies on leprosy in recent years, especially in the area of Tropical Medicine, with a predominance of funding from Brazilian agencies, and whose largest source of publications is an international scientific journal dedicated to the study of neglected tropical diseases. It can be concluded that the interest in the study of the topic has increased over the years, but among the topics evidenced by the analysis undertaken, public policies for the control and elimination of the disease were incipient. It also reveals the need for greater scientific input on the topic stimulated by both government agencies and educational and research institutions, which can leverage reflections aimed at the implementation of effective political guidelines for the control and elimination of the disease.

RESUMO

BACKGROUND: The population of the U.S. is becoming more diverse every year. The field of dermatology is not following the same trend. OBJECTIVE: To assess the promotion of diversity in the field of dermatology by analyzing publications focused on diversity, compared to other specialties. METHODS: The PubMed database was systematically searched to identify publications focused on diversity from January 2008 to July 2019. The search criteria were as follows: dermatology/radiology/ophthalmology/ anesthesiology/orthopedic surgery/family medicine/ internal medicine/general surgery AND diversity/ diverse/racial/race/ethnic/ethnicity/cultural/culture/competency/competence. Comparisons were made using single-factor ANOVA and two-group t-tests. A qualitative analysis was performed for publications in the field of dermatology. RESULTS: From January 2016 to July 2019, there were 25 publications focused on diversity in dermatology (Mean=6.25, SD=2.06), compared to 6 in radiology (Mean=1.50, SD=1.29, P=0.01), two in ophthalmology (Mean=0.50, SD=0.58, P=0.01), two in anesthesiology (Mean=0.50, SD=1.00, P=0.01), 12 in orthopedic surgery (Mean=3.00, SD=1.41, P=0.04), 23 in family medicine (Mean=5.75, SD=2.22, P=0.75), 9 in internal medicine (Mean=2.25, SD=1.71, P=0.02), and 7 in general surgery (Mean=1.75, SD=0.50, P=0.02). CONCLUSIONS: Although the field of dermatology has suffered from a lack of racial/ethnic diversity, efforts to promote diversity via increased publications in the last four years have been stronger in dermatology compared to many other fields.

RESUMO

BACKGROUND: Over the past 20 years, China has experienced an increased popularity of Western medicine. The impact of Western medicine in China on the field of dermatology is not well characterized. OBJECTIVE: To assess the impact China has had on the field of dermatology by analyzing the total publications to six dermatological journals, compared to two other Asian countries: Japan and Korea. METHODS: PubMed was utilized to search for publications from China, Japan, and Korea within the past 20 years. Descriptive statistics were used to determine the average percentage change in publications during this 20-year period, and the average annual increase in total number of publications from each country. Comparisons were made using one-way ANOVA and two-group t-tests. RESULTS: From 1998 to 2019, there was a 24% average annual increase in publications from China (M=24.4, SD=24.5), compared to a 6% increase from Japan (M=5.6, SD=25.4, P=0.02) and 8% increase from Korea (M=7.8, SD=23.4, P=0.03). CONCLUSION: For the past 20 years, there has been a strong positive trend regarding the total number of publications from China. This finding might be related in part to an increased acceptance of Western medicine, which follows a similar trend during the time period we analyzed.

RESUMO

Fenton based treatments have received tremendous attention in the recent decades as viable strategies for soil and water remediation. There exist different processes associated to the Fenton oxidation. Efficiency, reaction chemistry, and environmental consequences of these processes vary according to the iron (Fe) activation techniques such as soluble Fe(II) (homogeneous Fenton process), soluble Fe(II) and chelating agent (modified-Fenton), Fe minerals or solids (heterogeneous Fenton), iron and UV light (photo-Fenton) and electro-Fenton oxidation. Despite immense amount of research articles and reviews related to the Fenton oxidation, no bibliometric study of this topic has been published to our knowledge. Bibliometric studies provide a useful means to track research output and scholarly trends in a field. Here, we conducted a bibliometric study of the publications on this theme (>4000 documents) published during the past three decades available from the Science Citation Index Expanded (SCI-EXPANDED) database of the Web of Science Core Collection (Clarivate Analytics). Based on the bibliometric analysis of 4349 documents, various essential research indicators were described such as the type and language of publications, the most prominent authors in this theme, the most impactful articles, research categories, journals, institutions, and the countries, that have made the greatest contribution to this theme along with potential research hotspots. This bibliometric study allowed visualization of the current landscape and future trends in this field to facilitate the future collaborative research and exchange of knowledge.

RESUMO

BACKGROUND: Since the beginning of the COVID-19 outbreak in December 2019, a substantial body of COVID-19 medical literature has been generated. As of June 2020, gaps and longitudinal trends in the COVID-19 medical literature remain unidentified, despite potential benefits for research prioritisation and policy setting in both the COVID-19 pandemic and future large-scale public health crises. METHODS: In this paper, we searched PubMed and Embase for medical literature on COVID-19 between 1 January and 24 March 2020. We characterised the growth of the early COVID-19 medical literature using evidence maps and bibliometric analyses to elicit cross-sectional and longitudinal trends and systematically identify gaps. RESULTS: The early COVID-19 medical literature originated primarily from Asia and focused mainly on clinical features and diagnosis of the disease. Many areas of potential research remain underexplored, such as mental health, the use of novel technologies and artificial intelligence, pathophysiology of COVID-19 within different body systems, and indirect effects of COVID-19 on the care of non-COVID-19 patients. Few articles involved research collaboration at the international level (24.7%). The median submission-to-publication duration was 8 days (interquartile range: 4-16). CONCLUSIONS: Although in its early phase, COVID-19 research has generated a large volume of publications. However, there are still knowledge gaps yet to be filled and areas for improvement for the global research community. Our analysis of early COVID-19 research may be valuable in informing research prioritisation and policy planning both in the current COVID-19 pandemic and similar global health crises.

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.
