A Bibliometric Analysis on Tuberculosis Research of Korea from 1979 to 2017

Bibliometric Analysis of Nontuberculous Mycobacteria Research in South Korea

BACKGROUND

Current research on nontuberculous mycobacteria (NTM) is multidisciplinary, necessitating proper organization to obtain comprehensive insight. Therefore, a bibliometric analysis was performed to identify NTM research characteristics in South Korea.

METHODS

The Web of Science was searched for NTM articles authored by Koreans at Korean institutions until March 2023. We collected data on authors, publication year, article type, study design, research area, citations, research institutes, and funding sources.

RESULTS

Of the 28,092 articles on NTM, Koreans authored 868. After excluding 167 unrelated studies, 701 relevant articles were analyzed. The first study was from 1992, with publication rates markedly increasing from 2004 onward. Basic research constituted 41.3% (n=290) of the papers, whereas clinical research represented 44.7% (n=313). Basic research consisted mostly of biochemistry studies (n=73, 10.4%), whereas clinical research primarily involved retrospective studies (n=118, 16.8%). Fifty-four institutions participated in NTM research, with the top five contributing to 71% (n=498) of the publications. The National Research Foundation of Korea was the most significant funding source, supporting 181 studies (32.5% of funded articles). Citation analysis revealed a median citation count of 10 (interquartile range, 3 to 13), with clinical research dominating the top-cited articles and a rise in publications in high-impact journals over time.

CONCLUSION

The quality and quantity of NTM research in South Korea has improved. However, it is concentrated in a few institutions and is largely funded by a few sources. Future research should use more diverse funding sources, be conducted in more institutions, and prioritize prospective study designs to enhance the understanding and treatment of NTM.

Deciphering drug discovery and microbial pathogenesis research in tuberculosis during the two decades of postgenomic era using entity mining approach

We examined literature on Mycobacterium tuberculosis (Mtb) subsequent to its genome release, spanning years 1999-2020. We employed scientometric mapping, entity mining, visualization techniques, and PubMed and PubTator databases. Most popular keywords, most active research groups, and growth in quantity of publications were determined. By gathering annotations from the PubTator, we determined direction of research in the areas of drug hypersensitivity, drug resistance (AMR), and drug-related side effects. Additionally, we examined the patterns in research on Mtb metabolism and various forms of tuberculosis, including skin, brain, pulmonary, extrapulmonary, and latent tuberculosis. We discovered that 2011 had the highest annual growth rate of publications, at 19.94%. The USA leads the world in publications with 18,038, followed by China with 14,441, and India with 12,158 publications. Studies on isoniazid and rifampicin resistance showed an enormous increase. Non-tuberculous mycobacteria also been the subject of more research in effort to better understand Mtb physiology and as model organisms. Researchers also looked at co-infections like leprosy, hepatitis, plasmodium, HIV, and other opportunistic infections. Host perspectives like immune response, hypoxia, and reactive oxygen species, as well as comorbidities like arthritis, cancer, diabetes, and kidney disease etc. were also looked at. Symptomatic aspects like fever, coughing, and weight loss were also investigated. Vitamin D has gained popularity as a supplement during illness recovery, however, the interest of researchers declined off late. We delineated dominant researchers, journals, institutions, and leading nations globally, which is crucial for aligning ongoing and evolving landscape of TB research efforts. Recognising the dominant patterns offers important information about the areas of focus for current research, allowing biomedical scientists, clinicians, and organizations to strategically coordinate their efforts with the changing priorities in the field of tuberculosis research.

Published trends and research hotspots of central venous catheter-associated thrombosis from 1973 to 2022: A scientometric analysis

This study aims to explore the intellectual landscape and research hotspots in the central venous catheter-related thrombosis (CVC-RT) research field. Studies discussing CVC-RT published from 1973 to 2022 in the Web of Science Core Collection database were retrieved on February 24th, 2022. Citespace was used to perform a scientometric analysis to identify the intellectual landscape and research hotspots in the research fields of CVC-RT. A total of 4358 studies were retrieved, with an ascending trend in publication numbers. The United States of America was the most influential country. The Journal of Vascular Access published the most studies, and McMaster University was the most prolific institution. The results showed that the focus population of CVC-RT research has changed from pediatric patients to cancer patients, the management of CVC-RT has become more formal and standardized, and the focused CVC type has shifted to port and peripherally inserted central catheters. In addition, seventeen active burst keywords were detected, such as patient safety, clinical practice guidelines, and postthrombotic syndrome. This study comprehensively reviewed publications related to CVC-RT. The research topics on patient safety, clinical practice guidelines, and postthrombotic syndrome related to CVC-RT may be future hotspots.

A Global Bibliometric Analysis of Hallux Valgus Research (1999-2019)

Hallux valgus (HV) is a very common deformity among foot disorders, therefore attracting strong interest from foot and ankle surgeons. We investigated publication trends on HV in the literature. The analysis was conducted through an electronic search of the Web of Science database for publications between 1999 and 2019, studying the data of origin through bibliometrics. The following search string was utilized: TI = (hallux valgus* OR hallux abductovalgus*) with filters for the English language and documents in article format. The "Bibliometrix" package of R software was used for the bibliometric analysis, and the VOSviewer was used to create graphs. A total of 789 articles were found in the electronic search, with 2,723 cited articles. The most common Web of Science category was Orthopedics (83.0%), and Coughlin M.J. was the main researcher in this field with the largest number of publications (17). The United States led in terms of the number of published articles (26.7%). An increase in the number of publications over time was noted, with 2016 being the year with the highest number of articles (78). The journal with the most articles was Foot and Ankle International, with 35.2% of the publications. The number of published studies on HV has increased rapidly since 2012. The United States ranks first in related research worldwide. The journal with the most articles was Foot and Ankle International.
