When COVID-19 meets diabetes: A bibliometric analysis

Area of Science:

• Endocrinology and Metabolism
• Infectious Diseases
• Bibliometrics

Background:

• COVID-19 survivors report concerns about developing secondary health conditions.
• Diabetes mellitus is a significant concern among post-COVID-19 patients.
• Understanding research trends is crucial for managing long-term health implications.

Purpose of the Study:

• To analyze global scientific research trends on diabetes associated with COVID-19.
• To identify key authors, institutions, and countries contributing to this research area.
• To map the evolution and focus of research from 2020 to 2023.

Main Methods:

• Bibliometric analysis of 7,348 papers from the Web of Science Core Collection (Jan 2020–Dec 2023).
• Utilized CiteSpace 6.2.R6 for visual mapping and analysis.
• Keywords and co-citation analysis identified central themes like clinical characteristics, diabetes mellitus, metabolic syndrome, and angiotensin-converting enzymes.

Main Results:

• China and the United States lead in publications, with Harvard Medical School, Wuhan University, and Huazhong University of Science and Technology as top institutions.
• Khunti Kamlesh and Rizzo-Manfredi are identified as leading authors.
• Research predominantly focuses on clinical characteristics, with significant attention to metabolic syndrome and angiotensin-converting enzyme roles.

Conclusions:

• Research on COVID-19 and diabetes has rapidly expanded, primarily focusing on clinical observations.
• This analysis provides insights into research hotspots and collaborations, informing future strategies.
• Findings are vital for developing treatment protocols, directing future research endeavors, and guiding clinical practice for COVID-19 survivors with diabetes.
