Visual analysis of lung neuroendocrine tumors based on CiteSpace knowledge graph

Abstract

ObjectiveThe relevant literatures in the field of pulmonary neuroendocrine tumor were analyzed to understand the lineage, hot spots and development trends of research in this tumor.MethodThe Web of Science core collection was searched for English-language literature about neuroendocrine tumors of the lung published between 2000 and 2022. CiteSpace software was imported for visualization analysis of countries, institutions, co-cited authors and co-cited journals and sorting of high-frequency keywords, as well as co-cited references and keyword co-occurrence, clustering and bursting display.ResultsA total of 594 publications on neuroendocrine tumours of the lung were available, from 2000 to 2022, with an overall upward trend of annual publications in the literature. Authors or institutions from the United States, Italy, Japan and China were more active in this field, but there was little cooperation among the major countries. Co-cited references and keyword co-occurrence and cluster analysis showed that research on diagnostic instruments, pathogenesis, ectopic ACTH signs, staging and prognosis and treatment was a current research hotspot. The keyword bursts suggested that therapeutic approaches might be a key focus of future research into the field for pulmonary neuroendocrine tumors.ConclusionOver these 20 years, research related to neuroendocrine tumors of the lung has increased in fervour, with research on diagnostic instruments, pathogenesis, ectopic ACTH signs, staging and prognosis, and treatment being the main focus of research. Therapeutic treatments may be the future research trend in this field.

The research progress and research trends in acute coronary syndrome nursing: A review of visual analysis based on the Web of Science database

“…The circle in the figure indicates each country or institution node, the larger the area, the more publications; the connecting line indicates a cooperative relationship; when the intermediary centrality of the node is > 0.1, the circle will appear purple outer circle, which represents that the node has an important role in the process of information transmission. [12–14] The results show that a total of 121 countries and 387 institutions have published literature on ACS care research, and there is strong communication and cooperation between institutions in each country. The top 5 countries in terms of the number of publications USA (1319), England (436), Australia (326), Italy (311), Canada (309), and China (279) ranked 7th; the top 5 countries in terms of centrality Togo (0.25), South Africa (0.21), Mexico (0.18), Tunisia (0.16) and Senegal (0.15).…”

“…The red line in the figure indicates the time period of keyword bursts. [ 13 ] The top 20 burst words with higher weights in the field of ACS care from 2013 to 2022 are shown in Figure 8 . The research hotspots from 2013 to 2015 are mainly focused on immediate measurement of Cardiac Troponin, heart association, United States, early diagnosis, performance, randomized trial, emergency; and from 2016 to 2018, the research focus was mainly on platelet inhibition and acute heart failure; 2019 to 2022, angiography, statement and insights, risk scores, epidemiology, cardiovascular disease, cardiogenic shock, hospital mortality, and Kawasaki disease have dominated ACS care research in recent years.…”

“…It can qualitatively and quantitatively analyze the authors, institutions, countries, journals, and co-cited literature of a certain research field, and intuitively reflect the research hotspots and research frontiers of a certain research field in the form of dynamic mapping. [ 11 – 13 ] This advantage cannot be realized by traditional reviews. Therefore, this study intends to use bibliometric research methods to demonstrate the research hotspots and development trends in the field of ACS nursing in the past 10 years in the form of visual mapping by visualizing countries, institutions, authors, co-cited literature, and keywords, so as to provide a reference for the future research on ACSs.…”
