UX Caucus Database Tips

You might think that a recent publication indexed in PubMed with Epilepsy, Temporal Lobe* / pathology  would be retrieved by this query in Ovid MEDLINE :   *Epilepsy, Temporal Lobe / pa [Pathology]   You would be incorrect. One example is Xie K, Royer J, Larivière S, et al. Atypical connectome topography and signal flow in temporal lobe epilepsy. Prog Neurobiol. 2024;236:102604 . doi:10.1016/j.pneurobio.2024.102604.  and you can compare for yourself by searching for 38604584.ui in your preferred Ovid Medline segment, where it will show   This issue, of Major Topic MeSH-with-subheading not being accurately imported into Ovid, seems to affect literally every article since mid-2022 with a Heading/subheading combination marked as a Major Topic. What’s happening, and why? At the moment of intake processing, Ovid breaks apart headings consisting of a Major Topic and subheading.   NLM Data Ovid HIV Infections* ...

Many thanks to Molly K. Maloney, Pharmacy Liaison Librarian, University at Buffalo, mkm9@buffalo.edu, and Marijane White, Data and Research Engagement Librarian, Oregon Health & Science University, whimar@ohsu.edu for this week’s tip. Molly and Marijane would like to acknowledge and thank Barbara S. Reich, Director, Medical Library, Hackensack University Medical Center, barbara.reich@hmhn.org, Paije Wilson, Health Sciences Librarian, University of Wisconsin-Madison, paije.wilson@wisc.edu, and Michelle L. Zafron, Associate Librarian, University at Buffalo, mlzafron@buffalo.edu for their contributions to this conversation. In a recent post on the Expert Searching mailing list, Molly asked, "In helping a student craft a search that includes a MeSH term with subheading, I realized I was assuming the subheading carry over to the child terms when exploded. As an example, if searching for "Mental Disorders/pathology"[Mesh] will you also get "Anxiety Disorders/pathology...

Did you know that in addition to main headings and subheadings, CINAHL also uses tertiary subheadings? You've probably seen them in the Major and Minor Subject fields, but (if you are like me) you likely didn't notice them. In the example below, "Michigan" is a tertiary subheading linked to the heading "Colleges and Universities." At first glance it appears to be a subheading like "Prevention and Control," but in this case, it's actually different! This example shows the "Michigan" tertiary subheading linked to a heading and subheading: From the EBSCO help documentation ,  "Tertiary headings are used to indicate an age group or geographics . These headings are added when the age group or geographic area is key to the topic under discussion. The tertiary headings can be linked directly to CINAHL subject headings or to the end of a subject heading/subheading combination."  For example, these are the Age Group tertiary s...

ETA: Many thanks to Whitney Townsend for being a second set of eyes to check my testing strategies! Building on our earlier post, Tip #25: Using Subheadings in PubMed , here are some more fun things to know about PubMed's subheadings...  Did you know that PubMed's subheadings have their own hierarchy? You can see the full list of Subheadings categories in the MeSH database . And just like you find with other MeSH terms, PubMed also automatically explodes subheadings.  For example, when you search "Blood Glucose/analysis"[Mesh] , you are getting all of the relevant lower-level subheadings under "analysis" [Subheading].  This MeSH and subheading combo includes: "Blood Glucose/ analysis "[Mesh] "Blood Glucose/ blood "[Mesh] "Blood Glucose/ isolation and purification "[Mesh] "Blood  Glucose/ cerebrospinal fluid "[Mesh] In the screenshot below, you can see that ORing the other subheadings in doesn't increase or chang...
