The easiest way to do this is using a saved search in PubMed. You can either have the results emailed to you, or you can go to PubMed and run the search, or both.
In order to save a search in PubMed you need to use a My NCBI account. After logging into or creating your account (you can use a 3rd party sign option), run your search in PubMed.
Select "Create Alert" under the search box. Follow the instructions to either email yourself alerts or just save the search to your My NCBI account.
