Bibliometric and visualized mapping: two decades of lipidomics, with special focus on pregancy and women

To perform a bibliometric visualization in lipidomics-related research with two decades. The primary data was retrieved from the Web of Science, three sotwares (VOSviewer, CiteSpace, and R) provided an overview of this field. The countries, institutions, authors, key terms, and keywords were tracked and corresponding mapping was generated. From January 1st in 2001 to March 21th in 2022, 45,325 authors from 234 organizations in 101 countries published 7,338 publications in 382 journals were found. Journal of Lipid Research was the most productive (284 publications) and highly cited journal (18,293 citations). We clustered four keywords themes. The niche theme were shotgun lipidomics, tandem mass-spectrometry, and electrospray-ionization. The motor theme were expression, diseases, and inflammation. The emerging or decling theme were identification, mass-spectrometry, and fatty acids.The basic theme were metabolism, cell, and plasma. Though eight categories the lipid were classified, the keywords showed two of which were got more attention for research, fatty acyls and glycerophospholipids. The top 3 lipidomics-favoured diseases were insulin resistance, obesity, and Alzheimer’s disease. The top 3 lipidomics-favoured tissue was plasma, brain, and adipose tissue. Burst citations show “women” and “pregnancy” with the strength of 8.91 and 7.1, both topics may be a potential hotspot in the future. ### Competing Interest Statement The authors have declared no competing interest. ### Funding Statement This study did not receive any funding. ### Author Declarations I confirm all relevant ethical guidelines have been followed, and any necessary IRB and/or ethics committee approvals have been obtained. Yes I confirm that all necessary patient/participant consent has been obtained and the appropriate institutional forms have been archived, and that any patient/participant/sample identifiers included were not known to anyone (e.g., hospital staff, patients or participants themselves) outside the research group so cannot be used to identify individuals. Yes I understand that all clinical trials and any other prospective interventional studies must be registered with an ICMJE-approved registry, such as ClinicalTrials.gov. I confirm that any such study reported in the manuscript has been registered and the trial registration ID is provided (note: if posting a prospective study registered retrospectively, please provide a statement in the trial ID field explaining why the study was not registered in advance). Yes I have followed all appropriate research reporting guidelines, such as any relevant EQUATOR Network research reporting checklist(s) and other pertinent material, if applicable. Yes All data produced in the present study are available upon reasonable request to the authors. * PUFA : Polyunsaturated fatty ARA : Arachidonic acid DHA : Docosahexaenoic acid ICD : International Classification of Diseases PC : Phosphatidylcholine PE : Phosphatidylethanolamine
