A bibliometric analysis of segmentectomy versus lobectomy for non-small cell lung cancer research (1992-2019)

Hotspots and trends of electrochemical biosensor technology: a bibliometric analysis from 2003 to 2023

As a powerful tool for biological sensing, electrochemical biosensors have attracted much attention due to their ability to integrate biological recognition elements on an electrochemical interface and convert target analyte information into measurable electrochemical signals. Despite the abundance of literature published on the topic, no comprehensive surveys have been conducted to evaluate the area of electrochemical biosensors with bibliometric techniques. This paper employs VOSviewer to analyze and visualize literature from 2003 to 2023 in the Web of Science in order to gain an understanding of the development of the field of electrochemical biosensors in recent years. Co-occurrence and co-citation analysis are employed to identify research hotspots, trace evolutionary paths, and comprehend development trends in the field. Moreover, by analyzing highly cited and representative literature from different time periods, it is possible to recognize the major research hotspots and grasp the development pulse. The results of this study provide a comprehensive overview of the field of electrochemical biosensors and can be used to guide future research.

Bibliometric analysis of global research trends on small-cell lung cancer (2012–2021)

Background

Small-cell lung cancer (SCLC) is a recalcitrant tumor with a poor prognosis. With the rise of SCLC research in the past decade, this study aims to analyze the foundation and frontiers of SCLC research through bibliometric analysis.

Methods

Relevant publications from the Web of Science Core Collection were retrieved on January 3, 2022. R package bibliometrix and EXCEL2019 were used to analyze quantitative variables. Bibliometric mapping was constructed by VOS viewer and CiteSpace software to visualize citation, co-authorship, co-occurrence, and co-citation analysis of countries/regions, organizations, authors, references, and keywords.

Results

A total of 2,361 publications related to SCLC were identified with the total amount of articles steadily increasing, where China is the most productive country with 859 papers. Scholars and organizations from the United States, China, and Europe are primary sources of this research, among which the University of Texas MD Anderson Cancer Center made the most contribution to the field with 122 papers. Lung Cancer published the highest number of SCLC-related articles with a total of 121, while the Journal of Thoracic Oncology received the most citations totaling 3,098. Rudin, Charles M., and Sage, Julien are the most creative author. Leora, Horn, 2018, New Engl J Med and Rudin, Charles M., Nat Genet, 2012 can be categorized as classic literature owing to their high citations or strong sigma value. “Heterogeneity & Subtypes” and “Immunotherapy” may be the new frontiers in the SCLC domain.

Conclusion

Research on SCLC showed an upward trend based on the current global situation. Moreover, the current scope of collaboration in SCLC research is chiefly regional, which should further focus on transnational cooperation in the future. More attention should be devoted to “Heterogeneity & Subtypes” and “Immunotherapy”, which will be the hotspots in future research.

Dignity in nursing: A bibliometric and visual analysis of scientific publications

BACKGROUND

Dignity-conserved nursing has been widely studied by scholars all over the world; however, there is no clear direction in which this field is trending.

AIM

To conduct a bibliometric analysis that systematically characterises publications on dignity research in the nursing field from 2011 to 2020.

DESIGN

Bibliometric and visual analysis of retrieved articles.

METHODS

The Web of Science Core Collection database was used to retrieve all articles which addressed dignity in nursing from 2011 to 2020. The WoSCC's own analysis tool, CiteSpace and VOSviewer, were used to obtain visual analysis results. Reporting follows the STROBE checklist.

RESULTS

A total of 1429 papers on dignity care are included in this study. We found that the number of papers on this topic increased steadily, and the United States topped the list with 366 articles in total. The institute with the most publications was King's College London, and the most widely published journal was Nursing Ethics. We were able to identify four major research topics, namely dignity in: (a) palliative care, (b) dementia and the elderly, (c) health care and (d) nursing ethics. Terminally ill patient, home, value, rehabilitation and psychological distress were the five keywords with the highest burst strength.

CONCLUSIONS

The interest in dignity care research has been steadily increasing from 2011 and is reflected in the number of published papers. The United States and Western Europe are leading in this field, both having a high number of cutting-edge researchers and high-level scientific research institutions. In the domain of dignity care, several stable and high-yield core author groups have been formed. While the existing research mainly focuses on four hot spots, psychological distress, advanced cancer, maternity care and content analysis may be the research frontiers.
