"Wiener klinische Wochenschrift": publication patterns 1990-2000

The impact factor (Institute for Scientific Information, ISI, Philadelphia, PA, USA) is a widespread used and acknowledged source for judging the quality of a researcher. In addition the "Science Citation Index (SCI)" [Institute for Scientific Information (ISI)] provides the scientific community with a citations database indicating the number of cited references in indexed articles. For several reasons, the SCI seems to be more relevant. To evaluate the quality of the journal "Wiener klinische Wochenschrift", we assessed how often contributors to this journal have been cited during the last decade and which contributions have ranked as top papers. Moreover, with the aim of a more objective type of scientific evaluation, we have employed a new score, the "Citation Per Time Score (CPT-Score--the SCI divided by the number of years of observation, starting one year after publication). We have evaluated the total SCI for the years 1990 to 1994 and for the years 1995 to 1999. The number of total citations between the appearance of an article and the year 2000 was analyzed. The highest ranked publication of the whole decade (1990-2000) was a paper by G. Stanek with 40 citations. Furthermore, we have evaluated the "Top Ten Papers" of the journal. Interestingly, a steady increase of the total citation index of the journal "Wiener klinische Wochenschrift" over the last decade could be demonstrated. This study clearly shows that the citation rate of an article is not determined by the impact factor of the journal but rather the quality of the contribution. Moreover, the citation analysis of papers published in the last ten years in the "Wiener klinische Wochenschrift" shows a satisfactory citation rate for articles published in this journal. It is therefore definitely attractive to submit an article to a journal such as the "Wiener klinische Wochenschrift".     

肾移植前后未透析与透析效果及血液透析与腹膜透析的对比分析

背景:透析与肾移植都是治疗尿毒症的主要手段,由于肾源的不足,大部分尿毒症患者必须经过一段透析治疗来维持,等待接受移植肾源,虽然在透析期间患者能够得到较好状态,但近年来的未透析肾移植研究结果表明,移植前透析会对肾移植的效果有影响。目的:利用CNKI数据库文献检索和深度分析功能,对肾移植和透析研究的文献资料趋势进行多层次探讨分析。设计:文献计量学分析。资料提取:以电子检索方式对CNKI数据库2002-01/2011-12有关肾移植和透析研究的文献进行分析,采用检索词为"肾移植(Renal transplantation);透析(Dialysis)",对检索的相关文献运用数据库中自带的分析功能和Excel软件绘制图表的功能进行分析,通过文字和图表的形式将统计和计量数据分析,描述其分布特征。入选标准:纳入标准:①与肾移植相关的基础和临床研究论文。②与血液透析相关的基础和临床研究论文。③与腹膜透析相关的基础和临床研究论文。排除标准:①与文章目的无关的文献。②重复研究的文献。③刊社信息。④未发表的文献。⑤需电话追踪和手工检索逐一分析的文献。⑥年鉴。⑦护理内容的文献。主要数据判定指标:以CNKI数据库学术期刊文献出版时间、文献数量、学科类别、研究机构、来源期刊、文献被引频次、文献下载频次、关联文献、作者分布、基金资助情况和主要关键词进行相关分析。并对肾移植前后未透析与透析研究进行对比分析,以及血液透析与腹膜透析的研究进行对比分析。结果:在CNKI数据库学术期刊收录2002/2011的文献中,共检索到57篇与肾移植和透析研究相关的文献。文献数量产出趋于平稳状态,2004年和2008年文献产出数量最多;《中国组织工程研究与临床康复》杂志发表文献量为15篇,占全部文献的26.3%;透析研究以血液透析和腹膜透析的研究为主,还包括尿毒症患者生活质量的研究。选择肾移植还是透析治疗,需要综合考虑患者基本情况来选择最适合的肾替代治疗模式。结论:通过文献计量学方法对CNKI数据库学术期刊关于肾移植和透析研究的文献进行分析,可为中国从事肾移植和透析基础研究和临床实施的医务工作者进一步确定科研思路提供有价值的参考。     

Citation classics in critical care medicine

Objective The number of citations an article receives after its publication reflects its impact on the scientific community. Our purpose was to identify and examine the characteristics of the most frequently cited articles in the field of critical care medicine.Design The 74 top-cited articles in critical care journals were identified by a computer search using the database of the Science Citation Index Expanded (SCI-EXPANDED, 1945 to present) and the Web of SCIENCE. The 45 top-cited critical care articles in all other biomedical journals were identified using the database SciSearch (1974 to present) with the key word Critical Care.Results The most cited articles received 3402 and 2860 citations, respectively. The citation classics in critical care journals were published between 1968 and 1999 in six high-impact journals, led by Critical Care Medicine (37 articles), followed by the Journal of Trauma (21), and American Journal of Respiratory and Critical Care Medicine (9). Seventy articles were original publications, two were reviews or guidelines, and two were editorials. The top 45 classic articles in non-critical care journals were published in 13 different journals, led by the New England Journal of Medicine (11 articles), followed by JAMA and Lancet (6 articles each). The United States of America contributed most of the classic articles. Pathophysiology of the lung, sepsis and scoring systems were the primary focus of classic publications.Conclusions Our analysis gives a historical perspective on the scientific progress of critical care medicine and allows for recognition of important advances in this specialty.     

Recent trends in acupuncture for chronic pain: A bibliometric analysis and review of the literature

BackgroundAcupuncture has been increasingly used in patients with chronic pain, yet no bibliometric analysis of acupuncture studies for chronic pain exists.ObjectivesTo investigate the characteristics, hotspots and frontiers of global scientific output in acupuncture research for chronic pain over the past decade.MethodsWe retrieved publications on acupuncture for chronic pain published from 2011 to 2022 from the Science Citation Index Expanded (SCI-expanded) of the Web of Science Core Collection (WoSCC). The co-occurrence relationships of journals/countries/institutions/authors/keywords were performed using VOSviewer V6.1.2, and CiteSpace V1.6.18 analyzed the clustering and burst analysis of keywords and co-cited references.ResultsA total of 1616 articles were retrieved. The results showed that the number of annual publications on acupuncture for chronic pain has increased over time, with the main types of literature being original articles (1091 articles, 67.5 %) and review articles (351 articles, 21.7 %). China had the most publications (598 articles, 37 %), with Beijing University of Traditional Chinese Medicine (93 articles, 5.8 %) and Evidence-based Complementary and Alternative Medicine ranked first (169 articles, 10.45 %) as the most prolific affiliate and journal, respectively. Liang FR was the most productive author (43 articles), and the article published by Vickers Andrew J in 2012 had the highest number of citations (625 citations). Recently, "acupuncture" and "pain" appeared most frequently. The hot topics in acupuncture for chronic pain based on keywords clustering analysis were experimental design, hot diseases, interventions, and mechanism studies. According to burst analysis, the main research frontiers were functional connectivity (FC), depression, and risk.ConclusionThis study provides an in-depth perspective on acupuncture for chronic painstudies, revealing pivotal points, research hotspots, and research trends. Valuable ideas are provided for future research activities.     

Citation analysis of Canadian psycho-oncology and supportive care researchers

Purpose

The purpose of this study was to conduct a historical review of psycho-oncology and supportive care research in Canada using citation analysis and to review the clinical impact of the research conducted by the most highly cited researchers.

Methods

The lifetime journal publication records of 109 psycho-oncology and supportive care researchers in Canada were subject to citation analysis using the Scopus database, based on citations since 1996 of articles deemed relevant to psychosocial oncology and supportive care, excluding self-citations. Three primary types of analysis were performed for each individual: the number of citations for each journal publication, a summative citation count of all published articles, and the Scopus h-index.

Results

The top 20 psycho-oncology/supportive care researchers for each of five citation categories are presented: the number of citations for all publications; the number of citations for first-authored publications; the most highly cited first-authored publications; the Scopus h-index for all publications; and the Scopus h-index for first-authored publications. The three most highly cited Canadian psycho-oncology researchers are Dr. Kerry Courneya (University of Alberta), Dr. Lesley Degner, (University of Manitoba), and Dr. Harvey Chochinov (University of Manitoba).

Conclusions

Citation analysis is useful for examining the research performance of psycho-oncology and supportive care researchers and identifying leaders among them.     

Nursing research in three regions in China: a bibliometric study

PENG J., HUI Z.‐Y. (2011) Nursing research in three regions in China: a bibliometric study. International Nursing Review 58 , 21–25 Objective: To analyse scientific papers published by Chinese authors in nursing journals included in the Science Citation Index Expanded and compare the published scientific papers from mainland China (ML), Taiwan (TW) and Hong Kong (HK). Methods: All articles published in 62 journals that were related to nursing originating from ML, TW and HK from 1999 to 2008 were retrieved from the PubMed and Institute for Scientific Information (ISI) Web of Knowledge database. The total number of articles published in nursing journals, impact factors and citation reports and articles were estimated for quantity and quality comparisons. Results: The number of articles from the three regions increased significantly from 1999 to 2008. There were 1015 articles in total from the three regions: ML (48), HK (414) and TW (553) in PubMed. In the ISI Web of Knowledge database, TW derived the highest total citations (1755 citations from 500 articles), followed by HK (1316 citations from 347 articles) and ML (158 citations from 55 articles). HK had the highest average citations of 3.79, followed by TW (3.51) and then ML (2.87). Discussion: The difference between the quantity and quality of nursing research articles published in ML, TW and HK is significant, although the gap appears to be narrowing. Long‐term job stresses, low levels of education and language barriers are likely the main factors. ML, TW and HK have the same culture and ethnicity. We expect that ML will benefit significantly from increased exchanges with TW and HK in nursing research and education. We also speculate that TW and HK will benefit from exchanges because ML may have diverse nursing problems.
