ProQuest Dialog MEDLINE and ToxFile reload 2018: now complete - Jan 2018

Every year, MEDLINE® and ToxFile® are reloaded on ProQuest Dialog when the National Library of Medicine (NLM) re-indexes relevant documents from the whole database with changed medical terms. The 2018 reload of MEDLINE and ToxFile was completed on Sunday, January 14.
Due to the reload, ProQuest Dialog did not update MEDLINE or ToxFile from Friday, January 12 at 9 a.m. ET through Sunday, January 14 at 6 p.m. ET. The databases was available, but no new content was loaded during that time.
All documents in MEDLINE and ToxFile now reflect 2018 changes. You may need to update your searches and alerts with the 2018 MeSH vocabulary.

MeSH vocabulary changes for 2018

Information on the 2018 MeSH vocabulary from the NLM can be found here

One example of a significant change in 2018 is that contraindications, or CT, is no longer used as a qualifier/subheading. This term has been promoted to a full, explodable MeSH term: mesh.exact(Contraindications), which has two narrower terms – mesh.exact("Contraindications, drug") and mesh.exact("Contraindications, procedure"). You will need to update appropriate alert strategies for continued retrieval of this concept.

The MEDLINE ProSheet has been updated to reflect these changes.

If you have any questions about any of these changes, please contact your account manager or our customer experience team at
