changes to mesh
Changes to MeSH
  • New MeSH terms
    • Evidence-Based Dentistry
    • Evidence-Based Nursing
    • Evidence-Based Practice
    • Integrative Medicine
  • New age check tag: Young Adult
    • 19-24 (U.S. Census definition)
  • Summary of changes: http://www.nlm.nih.gov/pubs/techbull/nd08/nd08_medline_data_changes_2009.html
mesh database
MeSH Database
  • Search with MeSH terms (Headings, Subheadings, Publication Types); Supplementary Concept terms (Substance Names); Pharmacological Action terms
  • See scope note and other helpful information
  • Display MeSH terms in the hierarchy
  • Limit MeSH terms to a major concept
  • Attach subheadings
  • Link to NLM MeSH Browser
floating a subheading
Floating a Subheading
  • Definition: Search for a subheading without attaching it to a particular MeSH heading
  • Goal: Broader retrieval (but less precision)
  • Examples
    • Not sure which drug should be used for therapy? /tu
    • Not sure which drug caused the adverse effect? /ae
    • The subheading aspect is of interest, but it is not associated with the searched MeSH term
    • Indirect questions: What conditions does smoking affect?
