The National Library of Medicine (NLM) is currently involved in MEDLINE year-end processing (YEP) activities. These include changing the Medical Subject Headings (MeSH) main headings and subheadings as well as Supplementary Concept Records that standardize names and associated numbers for chemicals, protocols, and diseases that are not main headings. The MeSH edits include maintaining existing MEDLINE citations to conform with the 2016 version of MeSH, and other global changes.
- November 18, 2015: NLM expects to temporarily suspend the addition of fully-indexed MEDLINE citations to PubMed. NLM will continue to add Publisher-supplied and in process citations.
- Mid-December 2015: PubMed MEDLINE citations, translation tables, and the MeSH database will have been updated to reflect 2016 MeSH.
For details about the impact on searching from November 19 to mid-December, see: Annual MEDLINE/PubMed Year-End Processing (YEP): Impact on Searching During Fall 2015. For background information on the general kinds of changes made annually, see: Annual MEDLINE/PubMed Year-End Processing (YEP): Background Information.
English translations of article titles in other languages display in PubMed whenever they are available. In the past, when a translation was not available, the title display in PubMed would read “Not available” or similar wording. PubMed has been updated to display the title in the original language when a translation is not available. Note that this change does not affect PubMed searching. The default title search includes only English titles and title translations. To search titles in the original language, select the “Transliterated Title” field that includes both transliterated and vernacular titles from the Advanced Search page or use the field tag [tt].
PubMed has introduced a new type of link called “Articles Frequently Viewed Together” to assist with locating important articles on a given topic. For some PubMed abstracts, this feature will appear in the “Related Information” section in the right column. Currently, only 1.3 million out of the 24 million records in PubMed have this link. The calculation is based on anonymous click data for the last year, so older articles will be especially underrepresented. To find all articles with these relationships, search PubMed with the query “pubmed_pubmed_alsoviewed[filter]” and add additional terms to narrow the focus to your area of interest.
The NLM exhibit booth at the 2015 Annual Meeting of the Medical Library Association in Austin, TX, featured theater presentations to bring users up-to-date on several NLM products and services. The presentation recordings are captioned and accessible from the NLM Distance Education Program Resources page. The presentations include:
Note: To listen to the voice recordings and view the captions you may need the latest version of Flash® Player (download for free from the Adobe Web site). To maximize the presentation, use the Full Screen button. For more information, go to the NLM Technical Bulletin page.
The PubMed “Related citations” feature will soon be renamed to “Similar articles.” “Similar articles” was chosen because “Related citations” is ambiguous. There are several types of relationships that articles may have. The algorithm to generate the results has not been modified. The link name will be updated on the Summary results. The Abstract display discovery tool title will also be renamed. To see illustrations of the new feature, visit the NLM Technical Bulletin.
The MEDLINE/PubMed Search and Health Literacy Information Resources page and its preformulated Health Literacy Special Query have been updated to keep pace with the growing body of relevant literature. The Health Literacy Special Query now retrieves additional citations to articles about numeracy, comprehension of informed consent, and health insurance comprehension. The dynamic MEDLINE/PubMed health literacy search retrieves more than 8,000 citations to English language journal articles related to Health Literacy. PubMed filters can be used to limit to particular years, research or publication types. To limit citations to a particular subject (such as “decision making”) use the Advanced Search features.
Sometimes called Quantitative Literacy (QL) or Quantitative Reasoning (QR), numeracy involves skills needed to select a health insurance plan, choose treatments, and understand medication instructions. MEDLINE/PubMed may contain citations to articles that discuss numeracy skills of clinicians—physicians, nurses, and other health professionals who must communicate with patients and the public. Informed consent comprehension is of great interest to health literacy advocates and researchers who are concerned with how effectively health care providers communicate disease and treatment risks and benefits to patients. Among the more than 16,000 citations to articles with Informed Consent as a major descriptor, many citations don’t explicitly use the phrase “health literacy,” but are conceptually tied to it.
The selected resources on the right side of the MEDLINE/PubMed Search and Health Literacy Information Resources page includes new links, such as:
PubMed Mobile has been updated with several new features including additional filters, sort selections, trending articles, and related searches. Illustrations are included in a recent article published in the NLM Technical Bulletin.
Filters include: Article types (Books and documents, Clinical trials, Meta-analysis, Randomized controlled trials, Review articles, Systematic reviews); Text availability (Free full text, Full text); and Publication dates (5 years, 10 years). “Trending Articles” appears on the homepage. Discovery tools display below the results on mobile devices with smaller screen sizes.
The National Library of Medicine Training Center (NTC) has announced a new online class, Advanced PubMed Tips, Tricks, and Tools: MeSH. It is a FREE 90-minute online class using Adobe Connect, worth 1.5 MLA CE credits. This class covers several advanced concepts in the use of Medical Subject Headings (MeSH) for searching via PubMed. Topics include annual updates to MeSH, the effective use of subheadings, free floating subheadings, and examples of commonly confused terms. The course is intermediate level, intended for those with at least beginning knowledge of PubMed and MeSH. Upcoming class dates are April 2, April 16, July 9, and July 16.
Register now! Class enrollment is limited. For questions, contact the NTC trainers.
PubMed users continue to report an issue where the menu choices do not display when using the PubMed “Send to” feature. When this was first reported, it was determined that the problem occurs for those using older browsers (Internet Explorer 7 and 8) not supported by PubMed, or using “Compatibility View” in newer browsers (IE10 or 11). Users encountering this issue should upgrade to a more current version of Internet Explorer (IE10 or IE11) or use Firefox. DOCLINE users with new or upgraded browsers should configure their browser settings according to DOCLINE System Requirements to ensure full functionality. PubMed users should refer to the Browser Advice for NCBI Web Pages site.
DOCLINE users who are unable to upgrade or change browsers at this time can work around the issue by opening two separate browser tabs or windows, one for PubMed and the other for DOCLINE. This will allow them to search PubMed in one window/tab, then copy & paste the PMIDs from PubMed into DOCLINE in the other window/tab. Users of IE10 or IE11 experiencing the issue should check that “Compatibility View” is turned off, as follows:
- Open Internet Explorer
- Click Tools
- Click Compatibility View settings
- Uncheck “Display all websites in Compatibility View” or remove DOCLINE from the list of “Websites you’ve added to Compatibility View”
- Close & reopen Internet Explorer
Note to QDPortal users – if you experience the PubMed “send to” issue with a current browser version, contact QuickDoc customer at firstname.lastname@example.org, or by phone at (617) 738-1800.
Do you know any stories about people using NLM resources to find out something interesting, forge a new path, or improve their lives in a unique or dramatic way? Or, more simply, have you ever found just the right information at just the right time, for yourself or for a patron? For this year’s theater presentations at the Medical Library Association annual meeting in Austin, TX, NLM staff members who develop the resources are interested in teaming with the librarians who use them. They are interested in stories (great and small) about any NLM resource, but especially:
- Health Services Research Resources on Comparative Effectiveness, Patient Centered Outcomes, Health Technology Assessment
- DIMRC and other disaster resources
- BIBFRAME and Linked Data
- History of Medicine social media (e.g., Circulating Now)
- PubMed Central
- PubMed Health
Anyone interested in sharing their story should contact Kate Majewski at NLM.
