文献计量视角下的结核分枝杆菌潜伏感染研究现状与展望

Research status and future prospects of latent tuberculosis infection from a bibliometric perspective

目的:采用文献计量学方法对结核分枝杆菌潜伏感染研究近10年的相关文献进行分析,帮助研究人员了解该领域研究现状与趋势。方法:基于Web of Science核心合集数据库中科学引文索引扩展版,检索字段设定在主题,使用的关键词主要包括:“Latent Tuberculosis”或“Latent TB”或“LTBI”等。检索时间为2024年5月13日,文献的最终出版时间限定为2014—2023年,文献类型限定为原始研究性论文、综述,语言限定为英语,共获得相关文献4210篇。借助VOSviewer软件将结果可视化,从发文趋势、期刊分析、高被引论文分析、国际科研合作网络及关键词聚类等角度进行深入分析和讨论。结果:自世界卫生组织2015年提出结核分枝杆菌潜伏感染干预策略以来,话题持续获得全球学术界的关注,2014年1月至2023年12月共发表相关文献4210篇,总被引次数74324次,篇均被引次数17.65次;其中,美国发文量最多(1314篇,31.21%),其次是中国(587篇,13.94%)。国际科研合作网络分析结果显示,结核分枝杆菌潜伏感染领域研究形成了以美国、中国、英国、印度和意大利等为主体的国家间紧密合作;关键词聚类提示,结核分枝杆菌潜伏感染领域当前主要研究热点为:结核分枝杆菌潜伏感染的免疫机制、结核分枝杆菌潜伏感染的综合管理、结核分枝杆菌潜伏感染与风湿性疾病和结核分枝杆菌潜伏感染的筛查等。结论:本文揭示和讨论了结核分枝杆菌潜伏感染领域的研究现状及展望,可为该领域相关研究机构和学者提供一定借鉴和参考。

Objective:This study employs bibliometric analysis to examine the literature on latent tuberculosis infection(LTBI),with the goal of providing researchers with a comprehensive understanding of the current research landscape and future trends.Methods:The analysis was conducted using the expanded version of the Science Citation Index in the Web of Science Core Collection database,with the search field set to the topic.The primary keywords included‘Latent Tuberculosis’‘Latent TB’and‘LTBI’.The literature search was conducted on May 13,2024,and the publication period was restricted to 2014—2023.Only original research articles and review papers published in English were included,resulting in a total of 4210 relevant publications.VOSviewer software was employed to visualize the data and perform an in-depth analysis of the LTBI research field,focusing on publication trends,journal analysis,highly cited papers,international research collaboration networks,and keyword clustering.Results:Since the World Health Organization introduced its LTBI strategy in 2015,the topic has garnered sustained attention from the global academic community.From January 2014 to December 2024,we identified 4210 relevant articles,which collectively received 74324 citations,averaging 17.65 citations per article.The United States led in the number of publications(1314 articles,31.21%),followed by China(587 articles,13.94%).Analysis of international research cooperation networks revealed that latent tuberculosis infection research is marked by close collaboration among countries and regions,with the United States,China,the United Kingdom,India,and Italy taking leading roles.Keyword clustering indicated that the primary research focuses in this field currently include immunological mechanisms,comprehensive management,LTBI in the context of rheumatic diseases,and LTBI screening.Conclusion:This study highlights the current research landscape and future trends in the field of LTBI,offering valuable insights and references for research institutions and scholars.
