MEDLINE Reloaded and MeSH Thesaurus Updated for 2022 on STNext

The 2022 MEDLINE reload on STNext was completed on February 26, 2022. Records with updated indexing are now available in the file. No new fields were introduced in this reload.

At the same time, MEDLINE records included within Toxcenter were also updated. Finally, MEDLINE terminology used in indexing of diseases in BIOSIS also was made current.

Prior to the reload, the 2022 MeSH thesaurus was made available within MEDLINE. The annual MeSH update provides access to the latest terminology in biomedicine and is a tremendous resource for online searchers, along with the CAS Lexicon and Embase's Emtree thesaurus.

The updated MeSH contains 30,194 main headings, including 277 new headings. Some of the topics covered by the new headings include:

COVID-19 related terms

disease terminology

population groups

social determinants of health

If you are running Alerts (SDIs) in MEDLINE, we recommend reviewing them to see if the terminology in them should be expanded or replaced, based on the introduction of the new MeSH.
