Abstract:
The rising number of immunocompromised people has increased concerns about fungal infections as a severe public health issue. Invasive pulmonary fungal infections (IPFIs) are prevalent and often fatal, particularly for those with weakened immune systems. Understanding IPFIs is crucial. The work aims to offer a concise overview of the field's characteristics, main research areas, development paths, and trends. This study searched the Web of Science Core Collection on June 5, 2024, collecting relevant academic works from 2003 to 2023. Analysis was conducted using CiteSpace, VOSviewer, Bibliometrix Package in R, Microsoft Excel 2019, and Scimago Graphica. The study indicated that the USA, the University of Manchester, and Denning DW led in productivity and impact, while the Journal of Fungi topped the list in terms of publication volume and citations. High-frequency terms include "fungal infection," "invasive," "diagnosis," and "epidemiology." Keyword and trend analysis identified "influenza," "COVID-19," "invasive pulmonary aspergillosis," and "metagenomic next-generation sequencing" as emerging research areas. Over the last 2 decades, research on IPFI has surged, with topics becoming more profound. These insights offer key guidance on current trends, gaps, and the trajectory of IPFI studies.
Insights
Fungal infections pose a growing threat, especially to immunocompromised individuals. This study maps the research landscape of invasive pulmonary fungal infections, identifying key trends and emerging areas like COVID-19 impacts.
Area of Science:
- Medical Mycology
- Infectious Diseases
- Public Health
Background:
- Rising incidence of immunocompromised populations increases susceptibility to fungal infections.
- Invasive pulmonary fungal infections (IPFIs) represent a significant and often fatal public health concern.
- Comprehensive understanding of IPFI research is vital for effective management and prevention.
Purpose of the Study:
- To provide a bibliometric overview of IPFI research from 2003-2023.
- To identify key characteristics, research areas, development trajectories, and emerging trends in the field.
- To guide future research directions and highlight current knowledge gaps.
Main Methods:
- Bibliometric analysis of publications from the Web of Science Core Collection (2003-2023).
- Utilized CiteSpace, VOSviewer, Bibliometrix Package in R, Microsoft Excel, and Scimago Graphica for data analysis.
- Analyzed publication volume, citations, high-frequency keywords, and emerging research fronts.
Main Results:
- The USA, University of Manchester, and Denning DW are leading contributors.
- Journal of Fungi is the most prolific publication source.
- Key terms include 'fungal infection,' 'invasive,' 'diagnosis,' and 'epidemiology.'
Conclusions:
- IPFI research has significantly expanded and deepened over the past two decades.
- Emerging research areas include 'influenza,' 'COVID-19,' 'invasive pulmonary aspergillosis,' and 'metagenomic next-generation sequencing.'
- This analysis provides critical insights into the current state and future direction of IPFI studies.
