UNASSIGNED: Articles related to olfactory dysfunction published from 2002 to 2021 were located in the Web of Science Core Collection of Clarivate Analytics (London, UK). Bibliometric analyses were conducted with the CiteSpace (Chaomei Chen, Drexel University, Philadelphia, PA, USA) and VOSviewer (Center for Science and Technology Studies, Leiden University, Leiden, Netherlands) software programs.
UNASSIGNED: The number of articles published each year showed an upward trend, especially in 2020, where a sharp increase had occurred due to the coronavirus disease 2019 (COVID-19) pandemic. The United States was the country with the most publications and the strongest international cooperation. In terms of institutions, the greatest number of publications from a single institution came from Dresden University of Technology. Thomas Hummel was the author who had contributed the most articles. An analysis of co-citation networks and burst keywords in the field revealed a shift from \"gonadotropin-releasing hormone\" and \"apoptosis\" earlier on to \"olfactory training,\" \"COVID-19,\" and \"Parkinson\'s disease\" more recently. \"Outcome,\" \"COVID-19,\" \"infection,\" and \"pathogenesis\" are topics of the research frontier and hotspots.
UNASSIGNED: More attention has been paid to olfactory dysfunction as the understanding of it has improved in the past 20 years. This study provides researchers with an objective, systematic, and comprehensive analysis of the literature on olfactory dysfunction. The current frontier areas and hotspots in the field focus on the pathological mechanisms of olfactory dysfunction after infection with COVID-19 and its different prognoses. The pathophysiological mechanism of olfactory dysfunction in neurodegenerative diseases and COVID-19 will be a primary future research direction.
■2002年至2021年发表的与嗅觉功能障碍有关的文章位于ClarivateAnalytics的WebofScience核心合集(伦敦,英国)。使用CiteSpace进行了文献计量分析(ChaomeiChen,德雷克塞尔大学,费城,PA,美国)和VOSviewer(科学技术研究中心,莱顿大学,莱顿,荷兰)软件程序。
■每年发表的文章数量呈上升趋势,特别是在2020年,由于2019年冠状病毒病(COVID-19)大流行,疫情急剧增加。美国是出版物最多、国际合作最有力的国家。在机构方面,来自单一机构的最大数量的出版物来自德累斯顿理工大学。托马斯·胡梅尔是贡献文章最多的作者。对该领域的共引网络和爆发关键词的分析表明,从“促性腺激素释放激素”和“凋亡”转变为“嗅觉训练”,\"\"COVID-19,\"和\"帕金森病\"最近。\"结果,\"\"COVID-19,\"\"感染,“病机”和“病机”是研究的前沿和热点。
■在过去的20年中,随着对嗅觉功能障碍的理解的提高,人们对嗅觉功能障碍给予了更多关注。这项研究为研究人员提供了一个目标,系统,对嗅觉功能障碍的文献进行综合分析。目前该领域的前沿领域和热点集中在COVID-19感染后嗅觉功能障碍的病理机制及其不同预后方面。嗅觉功能障碍在神经退行性疾病和COVID-19中的病理生理机制将是未来的主要研究方向。
