Comparative study of scientific publications in urology and nephrology journals originating from USA, China and Japan (2001-2010).

ABSTRACT: BACKGROUND: In the past decade, scientific research has developed rapidly in China, but the growth seems to vary widely between different disciplines. In this study, we aimed to compare the quantity and quality of publications in urology and nephrology journals from USA, China and Japan. METHODS: Journals listed in the "Urology and Nephrology" category of Science Citation Index Expanded subject categories were included. Scientific papers in these journals written by researchers from USA, Japan and China were retrieved from the "PubMed" and "Web of Knowledge" online databases. RESULTS: The annual number of total scientific articles increased significantly from 2001 to 2010 in China, and has ranked second in the world since 2006. In the field of urology and nephrology, the annual number increased significantly from 2001 to 2010 in USA and China; but not in Japan. The share of articles increased significantly over time in China, decreased significantly in Japan, and remained unchanged in USA. In 2010, USA contributed 32.17% of the total world output in urology and nephrology field and ranked 1(st); Japan contributed 5.19% and ranked 5(th); China contributed 3.83% and ranked 9(th). Publications from USA had the highest accumulated IFs and the highest total citations of articles (USA>Japan>China, p<0.001). No significant difference was found in average IF among the three countries. USA published the most articles in the top 10 urology and nephrology journals (USA(35165)>Japan(6704)>China(2233), p<0.001). Researchers from USA published more clinical trials and randomized controlled trials than Japan and China (USA>Japan>China, p<0.001). CONCLUSION: Although China has undergone significant increase in annual number and percentage of scientific publication in urology and nephrology journals in the past decade, it still lags far behind USA and Japan in the field of urology and nephrology in terms of quantity and quality.

Project description:ObjectivesRheumatology-related diseases remain a significant burden worldwide. However, little is known about the comparative status of rheumatology research between Mainland China (MC) and the world's leading countries. The aim of this study is to compare the quantity and quality of research output in the field of rheumatology that were written by researchers from MC, the USA, the UK, the Netherlands and France.MethodsBetween 2007 and 2017, all articles published in 30 rheumatology journals were identified via Science Citation Index Expanded database. The number of total and annual articles, article types (randomized controlled trials (RCTs), reviews, case reports, clinical trials and meta-analysis), impact factor (IF), citations, h-index and articles in the high-impact journals were collected for quantity and quality comparisons. The correlation of socioeconomic factors and annual publications was also analyzed.ResultsFrom 2007 to 2017, there were 53,439 articles published in rheumatology journals, of which researchers from the USA published 13,391 articles, followed by the UK, the Netherlands, France and MC with 6,179, 4,310, 4,066 and 2,898 articles, respectively. Publications from MC represented the ninth, but the number is growing rapidly. For total and average citations, MC still lags behind the other four countries in the study. Similar trends were observed in average IF, h-index and articles in the high-impact journals. In terms of article types, the USA occupies the dominant place, except for meta-analysis. The annual numbers of articles from MC and the USA were positively correlated with gross domestic product (p < 0.05).ConclusionsThe USA has played predominant role in rheumatology research for the last 11 years. The annual number of published articles from MC has increased notably from 2007 to 2017. Although MC has made progress in the number of published articles over the past decade, it still lags far behind the highly developed countries in most bibliometric indicators. Thus, the general quality of publications from MC needs further improvement.

Project description:BackgroundAn increasing number of studies on dexmedetomidine use in adults have been published, but the effectiveness of dexmedetomidine remains contentious.ObjectiveThis study aimed to describe the changing trends and structural relationships of scientific achievements regarding dexmedetomidine over the past 2 decades and provide researchers with information to help them explore better research opportunities.MethodsQuantitative data of publications were retrieved from the Scopus database. Analyses of co-occurrence and collaboration among authors, countries, and key words were conducted using VOSviewer 1.6.17 software. Weighted occurrence and average publications per year were calculated.ResultsThe 1868 publications retrieved showed an increasing trend of annual publications on dexmedetomidine use in adults between 2001 and 2021. China accounted for the largest contribution to publications in the world (n = 577 [30.89%]). Four key word clusters indicating research hotspots were identified using VOSviewer. The number of articles published in the top 10% of journals in the United States was the highest among all publications from the country (97 out of 201 [48.26%]). Journals from the United Kingdom obtained the highest CiteScore (16.56). Journal of Anaesthesiology Clinical Pharmacology published the highest number of articles on this topic (n = 56). Wang authored the highest number of published articles (n = 42). Recent publications focused on the theme of cytokines and immunomodulation. Sufentanil attracted particular interest as a drug-related key word. Moreover, meta-analysis is becoming an increasingly popular research method in this field.ConclusionsThe increasing number of publications on dexmedetomidine use reflects growing interest in this topic. Future research should focus on meta-analyses to identify the most effective therapeutic methods. The immunomodulatory effect of dexmedetomidine on health and disease is of particular interest.
