Characteristics and Trends of Orthopedic Publications between 2000 and 2009

Background

This study was undertaken to investigate the trends of orthopedic publications during the last decade, and to document the country of origin, journal, funding source, and language of contribution using PubMed.

Methods

Orthopedic articles published between 2000 and 2009 were retrieved from PubMed using the following search terms: "orthopaedic[Affiliation] AND ("2000/1/1"[PDAT]: "2009/12/31"[PDAT])" and "orthopedic[Affiliation] AND ("2000/1/1"[PDAT]: "2009/12/31"[PDAT])." The articles were downloaded in XML file format, which contained the following information: article title, author names, journal names, publication dates, article types, languages, authors'' affiliations and funding sources. These information was extracted, sorted, and rearranged using the database''s management software. We investigated the annual number of published orthopedic articles worldwide and the annual rate of increase. Furthermore, the country of publication origin, journal, funding source, and language of contribution were also investigated.

Results

A total of 46,322 orthopedic articles were published and registered in PubMed in the last 10 years. The worldwide number of published orthopedic articles increased from 2,889 in 2000 to 6,909 in 2009, showing an annual increase of 384.6 articles, or an annualized compound rate of 10.2%. The United States ranked highest in the number of published orthopedic articles, followed by Japan, the United Kingdom, Germany, and the Republic of Korea. Among the orthopedic articles published worldwide during the last 10 years, 37.9% pertained studies performed in the United States. Fifty-seven point three percent (57.3%) of articles were published in journals established in the United States. Among the published orthopaedic articles, 4,747 articles (10.2%) disclosed financial support by research funds, of which 4,688 (98.8%) articles utilized research funds from the United States. Most articles were published in English (97.2%, 45,030 articles).

Conclusions

The number of published orthopedic articles has been increasing over the last decade. The number of orthopedic articles, journals publication, and funding sources were dominated by research conducted in the United States, while share and growth of Asian countries including Japan, the Republic of Korea, and China were notable.     

Top-cited articles in endodontic journals

Introduction

The purpose of this study was to identify the 100 top-cited articles published in journals dedicated to endodontology and analyze their characteristics to describe the quality and evolution of research in the field of endodontology.

Methods

The Institute for Scientific Information Web of Knowledge Database and the Journal Citation Report Science Editions were used to retrieve the 100 most cited articles published in journals dedicated to endodontics. The top-cited articles were selected and analyzed with regard to journals, authors, institution, country of origin, publication title and year, number of citations, article type, study design, level of evidence, and field of study.

Results

The top 100 articles were cited between 87 and 554 times. These articles appeared in 4 different journals, with more than half in the Journal of Endodontics, followed by the journals Oral Surgery Oral Medicine Oral Pathology Oral Radiology and Endodontology, the International Endodontic Journal, and Endodontics & Dental Traumatology. Forty-eight articles were published between 1990 and 1999. All articles were published in English and primarily originated from the United States (n = 52). The majority of articles were basic science articles (n = 55), followed by clinical research studies (n = 28) and nonsystematic reviews (n = 17). Uncontrolled case series with level IV of evidence and narrative reviews with level V of evidence were the most frequent types of study design. The main topics covered by the top-cited articles were microleakage and endodontic microbiology.

Conclusions

This analysis of citation rates reveals useful and interesting information about scientific progress in the field of endodontics. Basic research and observational studies published in high-impact endodontic journals had the highest citation rates.     

从文献回顾分析抗蠕虫药物的现状与发展趋势

目的 运用文献计量学方法对已发表的抗蠕虫药物文献进行分析,探讨抗蠕虫药物的现状和发展趋势。方法　 收集在PubMed数据库上收录的1997-2007年医学专业学术期刊抗蠕虫药物的相关文献,通过一定数据准入标准筛选符合要求的文献并构建Access数据库。对数据库中相关文献进行如“研究类型”、 “发表年代”、 “涉及药物”等分类项归类。用SPSS17.0软件对数据进行相应的线性回归和二次回归等统计学分析。 结果 抗蠕虫药物相关论文年度发表数量呈逐年增长趋势,年相关论文发表量增加约6篇;应用性研究为主要研究主题;主要研究病种依次为血吸虫病、丝虫病、蛔虫病、棘球蚴病和钩虫病,其中血吸虫病相关文献数量最多,与其他4种主要蠕虫病的相关文献数量差异均有统计学意义（P<0.05）;主要研究药物为阿苯达唑、吡喹酮、甲苯咪唑、伊维菌素和乙胺嗪;抗蠕虫药物相关文献在多种医学杂志上发表,发表抗蠕虫药物文献数量第1位和第10位的期刊分别占文献总数的5.52%和 1.63%。 结论 近10年来抗蠕虫药物愈来愈受到重视,但其种类不多,亟需发展新药。
