Updates to MeSH terms for 2020

The US National Library of Medicine has released the edits for their medical subject headings (MeSH) for 2020. These are used to index articles added to the PubMed and Medline databases, and are also used by other databases including the Cochrane Library. The MeSH terms are updated every year to incorporate new terminology or to re-classify existing terms with up to date definitions. Note that these changes are NOT retrospectively applied. Therefore you may need to incorporate old and new MeSH terms in your searches to retrieve all relevant articles. If you have saved searches or searches you run on a regular basis in order to stay up to date, it is important that you periodically update your search to make sure it continues to retrieve the papers you need.

Here are some of the edits which may be of interest to LSHTM users.
