Insights
This study analyzed top hepatology research during Coronavirus Disease 2019 (COVID-19). Key findings highlight trends in liver disease treatment and pathophysiology, aiding researchers in developing effective COVID-19 protocols.
Area of Science:
- Hepatology and Virology
- Infectious Diseases
- Medical Research Trends
Background:
- The Coronavirus Disease 2019 (COVID-19) pandemic significantly impacted global health, including hepatology.
- Understanding research trends is crucial for developing effective treatments and protocols for liver involvement in COVID-19.
Purpose of the Study:
- To analyze global hepatology research trends related to COVID-19 from 2019 to 2023.
- To identify the most influential articles, authors, and institutions in this field.
- To guide researchers and healthcare systems in addressing hepatic impairment during COVID-19.
Main Methods:
- Bibliometric analysis of the top 101 most-cited articles on COVID-19 and hepatology (2019-2023).
- Data extraction included citation counts, publication year, journal impact factor, author demographics (gender, H-index), country of origin, and funding.
- Analysis of article topics, focusing on therapeutic interventions and pathophysiology.
Main Results:
- The most cited articles were published in 2021, with the *American Journal of Transplantation* leading in contributions.
- The United States was the leading country, and the University of Pennsylvania was the most represented institution.
- Therapeutic intervention and pathophysiology were the most common research topics, with a male predominance among authors.
Conclusions:
- Top-cited articles focus on liver transplantation, pathophysiology, and healthcare management for COVID-19 patients.
- This analysis provides insights into effective treatment modalities for hepatic impairment in COVID-19.
- Findings can accelerate the development of advanced research protocols and clinical management strategies.
Objective:
Analyzing global hepatology trends during Coronavirus Disease 2019 (COVID-19) to accelerate effective treatments and protocols for researchers and healthcare systems.
Methods:
The related papers to COVID-19 and hepatology were extracted from 2019 to 2023. The articles were ranked according to the number of citations and a final list of top 101 most-cited articles were shortlisted. Analysis was carried out on the following: total citation count, publication year, journal name and its Impact factor, gender and their H-index, country of origin, funding information, and content of the articles. Citations per year and citations per author were calculated for all articles.
Results:
Between 2019 and 2023, the top 101 cited articles covered various topics. The highest number were published in 2021 (n = 42), with the American Journal of Transplantation contributing the most (n = 23). The University of Pennsylvania had the most influential presence (n = 5). These articles came from 44 countries where the US ranked first with 35 articles. There were a total of 160 authors involved, with each paper having a median and mean of 6 and 7.3 authors, respectively. The articles were categorized into nine main topics, with therapeutic intervention being the most common (n = 26) followed by pathophysiology (n = 20). Males outnumbered females as first and senior authors. A majority (n = 55) received funding, and most (n = 81) did not declare conflicts of interest.
Conclusion:
Top articles in our analysis focused on liver transplantation, pathophysiology, and healthcare management. It can aid researchers in assessing the effectiveness of different treatment modalities for hepatic impairment in COVID-19 patients.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
