Research trends of omics in ulcerative colitis: A bibliometric analysis

Abstract

BackgroundOmics has emerged as a promising biological science to shed light on the etiology, pathogenesis, and treatment of ulcerative colitis (UC). At present, although research on the omics of UC has drawn global attention, there is still a lack of bibliometric analysis in this field. This study aimed to access the trends and hotspots of omics in UC research.MethodPublications related to omics in UC from 1 January 2000 to 15 October 2022 were retrieved from the Web of Science Core Collection database. VOSviewer, CiteSpace, and the online bibliometric analysis platform “Bibliometrix” were adopted to extract and visualize information.ResultsA total of 385 publications were finally included and the annual number of publications fluctuated. The trend in publications increased rapidly after 2019. The United States showed its dominant position in several publications, total citations, and international collaborations. The top five research organizations for publications on the research of omics in UC were Harvard Medical School, the Icahn School of Medicine at Mount Sinai, Karolinska Institutet, the Brigham and Women's Hospital, and the Massachusetts General Hospital. Ashwin Ananthakrishnan from the Massachusetts General Hospital was the most productive author, and Séverine Vermeire from the Catholic University of Leuven was co-cited most often. Inflammatory bowel disease was the most popular and co-cited journal in this field. The reference with citation bursts and trend topics showed that “ulcerative colitis,” “inflammatory bowel disease,” “microbiome,” “transcriptomics,” “genomics,” “metabolomics,” “proteomics,” “dysbiosis,” “biomarkers,” “loci,” and “therapy” are currently research hotspots.ConclusionOur study presents several important insights into the research trends and developments in the field of omics in UC, which will provide key information for further research.

Bibliometric analysis and visualisation of research hotspots and frontiers on omics in osteosarcoma

“…The VOSviewer software tool (version 1.6.16) was used to explore the co-authorship (authors, organizations, and countries), co-occurrence (author and keywords), bibliographic coupling (sources), and co-citation (cited references, cited sources, and cited authors), was applied to create network visualization maps of the most cooccurrence terms to analysis the research hotspots and the most co-authorship of countries (Song et al 2022).In this map, items were called nodes re ecting author, country, organization, and keywords, and links re ecting the degree of collaboration of each item were represented by edges (Zhang et al 2023).…”
