Document Network and Conceptual and Social Structures of Clinical Endoscopy from 2015 to July 2021 Based on the Web of Science Core Collection: A Bibliometric Study

Journal metrics, document network, and conceptual and social structures of the Korean Journal of Anesthesiology from 2017 to July 2022: a bibliometric study

BACKGROUND

This study aimed to identify the directions of research published in the Korean Journal of Anesthesiology (KJA) and identify the main topics and journal network through a bibliometric analysis. The results can be reflected in strategies for the journal's promotion to a top-ranking journal in the anesthesiology category.

METHODS

KJA articles from January 1, 2017 to September 11, 2022 were retrieved from the Web of Science Core Collection on September 11, 2022, and analyzed using Biblioshiny. Journal metrics, the document network, the conceptual structure, and social structures were elucidated.

RESULTS

Out of 525 articles, fewer than half (48.6%) were from Korean corresponding authors. The impact factor steeply increased from 2.316 in 2019 to 5.167 in 2021. The Hirsch index of KJA was 24. A co-occurrence network of Keywords Plus showed four clusters of central keywords: surgery, management, anesthesia, and mortality. The conceptual structure map of Keywords Plus showed a main cluster of anesthesia and analgesia, while another minor cluster included intubation and induction. The co-citation network demonstrated that KJA was in the same cluster of anesthesiology journals. The collaboration network of the authors' countries showed that Korean authors collaborated mainly with researchers in the United States and Canada.

CONCLUSIONS

These results show KJA's developmental process of promotion to a top-tier journal in the anesthesiology category. Furthermore, the following strategies are suggested for journal promotion: recruitment of articles on emerging and highly citable topics; and more active collaboration of society members with researchers worldwide.

Research trends on endoscopic mucosal resection: A bibliometric analysis from 1991 to 2021

Background

In recent years, the rapid development of digestive endoscopy technology has brought revolutionary changes to endoscopic therapy. A growing number of articles have been published annually. We aimed to explore global scientific outputs and hotspots of endoscopic mucosal resection (EMR) published by different countries, organizations, and authors.

Methods

We extracted relevant publications from the Web of Science Core Collection (WOSCC) on June 23, 2022. We examined the retrieved data by bibliometric analysis (e.g., cocited and cluster analysis, keyword co-occurrence) using the software CiteSpace and VOSviewer to analyze and predict the trends and hot spots in this field.

Results

A total of 2,695 papers were finally identified. The results showed that the number of articles fluctuated with the year and reached its peak in 2021. NATIONAL CANCER CENTER JAPAN was the most influential institution. MICHAEL J BOURKE and YUTAKA SAITO are two of the most prolific scholars. ENDOSCOPY and GASTROINTESTINAL ENDOSCOPY were the most productive journals. “Early gastric cancer” and “Barrett's esophagus” were the focus of EMR research. “Adverse events”, “cold snare polypectomy” and “outcomes” have become increasingly popular in recent years and could become hot spots in the future.

Conclusion

In this study, we summarized the characteristics of the publications; identified the most influential countries, institutions, and journals; and identified the leading topics in the EMR field.

Promotion to Top-Tier Journal and Development Strategy of the Annals of Laboratory Medicine for Strengthening its Leadership in the Medical Laboratory Technology Category: A Bibliometric Study

Background

A bibliometric analysis of the Annals of Laboratory Medicine (ALM) was performed to understand its position in the medical laboratory technology category and to suggest a developmental strategy.

Methods

Journal metrics, including the number of articles by publication type, country of authors, total citations, 2-year impact factor, country of cited authors, journals citing ALM, and Hirsch-index, were obtained from the Journal Citation Report and Web of Science Core Collection. Target data included ALM content in the Web of Science from January 1, 2012, to October 5, 2021. Bibliometric analysis was performed using Biblioshiny.

Results

The impact factor increased from 1.481 in 2013 to 3.464 in 2020. Authors belonging to the USA, China, and Korea cited ALM articles the most. Plos One, Scientific Reports, and Frontiers in Microbiology most frequently cited ALM, besides ALM itself. The Hirsch-index was 34. The co-occurrence network of Keyword Plus indicated four clusters diagnosis, identification, prevalence, and risk. The conceptual structure map of Keyword Plus based on multiple correspondence analysis showed two clusters bacterial susceptibility at the bench and clinical courses. The co-citation network showed that ALM was in the cluster of the New England Journal of Medicine, The Lancet, JAMA, and the Annals of Internal Medicine. The collaboration network showed that Korean authors collaborated mainly with authors from the USA, Germany, and Italy.

Conclusions

The journal’s promotion to an international top-tier journal has been successful. “Principles of transparency and best practice in scholarly publishing” and a preprint policy are yet to be added.
