The National Library of Medicine (NLM) has updated its list of structured abstract labels. This updated list, along with the NLM-assigned broader category mappings, can be downloaded for free from the Structured Abstracts resource page which also provides NLM guidelines and other background information to assist licensees or researchers. A grand total of 4,702 citations (whether in process, MEDLINE, or PubMed-not-MEDLINE status) were revised so that the new labels include the NLM Category mapping in the XML data, effective on or about October 26, 2015. Of interest, the new label ‘TWEETABLE ABSTRACT’ (mapped to the NLM Category ‘CONCLUSIONS’) illustrates the impact of social media. Read more about Structured Abstracts in MEDLINE/PubMed.

The default year in NLM’s MeSH Browser is currently 2015 MeSH, with an alternate link that now provides access to 2016 MeSH. Access to two years of MeSH vocabulary is always available in the MeSH Browser, the current year and an alternate year. Sometime in November or December, the default year will change to 2016 MeSH and the alternate link to the 2015 MeSH. Details on updates and download information for 2016 MeSH are forthcoming.
In June 2015, NLM proposed discontinuing distribution of its bibliographic records with artificially reconstructed subject strings in CATLINE and SERLINE products, as detailed in the NLM Technical Bulletin article Discontinuing Distribution of Cataloging Bibliographic Records with Artificially Reconstructed Subject Strings—Comment by August 31, 2015. This proposal was sent to the Regional Medical Libraries, MEDLIB, and MEDCAT discussion lists, as well as to subscribers of the NLM MARC21 files. Responses to the proposal were unanimously in favor of discontinuing the distribution of subject strings and having the records in the distributed files match the records as they appear in LocatorPlus and the NLM Catalog.
Therefore, NLM is pleased to announce that beginning with the December 2015 distribution of new records in CATFILE and SERFILE, NLM subject terms will be distributed with topical subjects recorded in 650 $a or 650 $a $x; geographic subjects recorded in 651 $a or 651 $a $x; and publication type/genre terms record in 655 $a. In January 2016, the entire CATFILE and SERFILE databases will be released with these updates made to all the records. Libraries that want their data to be consistent with the NLM files are encouraged to download the full update.
Per capita personal income data is now complete for 1988-2013 in the National Library of Medicine’s TOXMAP beta resource. To overlay income data, navigate to the “Income” tab of the “US Census & Health” window, accessible via the Welcome window or the toolbar at the top of the page, and then select a year from the list. The United States Bureau of Economic Analysis (BEA) is part of the US Department of Commerce. It produces “economic accounts” statistics that enable government and business decision-makers, researchers, and the American public to follow and understand the performance of the nation’s economy. To do this, the BEA collects source data, conducts research and analysis, develops and implements estimation methodologies, and disseminates statistics to the public. TOXMAP is a Geographic Information System (GIS) from the Division of Specialized Information Services of the NLM that uses maps of the United States to help users visually explore data from the US Environmental Protection Agency (EPA)’s Toxics Release Inventory (TRI) and Superfund Program, as well as some non-EPA datasets.
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.
New Mobile App Connects HIV Providers, Advocates, and People Living with HIV/AIDS to NLM HIV-Related Websites
HealthHIV, in partnership with the National Library of Medicine (NLM), has announced the launch of the Go2NLM mobile application. Building on its Navigate to Learn More publication, HealthHIV created the Go2NLM app to provide information about and direct access to NLM’s authoritative HIV-related websites to HIV providers, advocates, and people living with HIV/AIDS. The app features dynamic content, including updates about new and highlighted HIV technical assistance and capacity building tools and resources promoted by NLM.
The websites featured on the Go2NLM app are:
- HIV/AIDS Information, NLM Specialized Information Services
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.
Registration and agenda information for the National Library of Medicine’s third annual DailyMed/RxNorm Jamboree Workshop is now available. The Jamboree is a free public meeting to be held on September 24, 2015, 9:30 am to 4:15 pm EDT, at the Lister Hill Auditorium on the NLM campus in Bethesda, MD. The session will also be webcast and archived for future viewing. Registration is required for attendance. Since 2015 marks the 10th anniversary of DailyMed, the meeting will feature a retrospective look at how industry has made use of DailyMed during that time.
Featured speakers will include representatives from the federal government, industry, academia and non-profit sectors. Speakers from the U.S. Food and Drug Administration, U.S. Pharmacopeial Convention, and Avalere Health will talk about biosimilars naming. Ed Millikan, representing the American Society of Health-System Pharmacists, will present an extended look at Risk Evaluation and Mediation Strategies. The meeting emphasis is on practical and novel ways to use and understand this free drug information, which is produced and consumed by a number of federal agencies.
The National Library of Medicine’s (NLM) Developmental and Reproductive Toxicology (DART) is a bibliographic resource on NLM’s Toxicology Data Network (TOXNET). It covers teratology and other aspects of developmental and reproductive toxicology and includes more than 200,000 references to literature published since the early 1900s. DART may be searched using MeSH terms/keywords, title words, chemical name, Chemical Abstracts Service Registry Number (RN), and author. Search results are displayed in relevancy ranked order, but may also be sorted by publication date, entry month, author, or title.
DART was initially funded by the U.S. Environmental Protection Agency, the National Institute of Environmental Health Sciences, the National Center for Toxicological Research of the Food and Drug Administration, and NLM. Some meeting abstracts and non-MEDLINE literature are historically included in DART; however, new citations come only from PubMed, based on a search strategy profile. New references are added weekly.
The U.S. Department of Health and Human Services launched the first online collection of the federal resources and capabilities available to mitigate the health impacts of emergencies. The HHS Office of the Assistant Secretary for Preparedness and Response (ASPR) sponsored the HHS Response and Recovery Resources Compendium to aid state, tribal, territorial, and local officials in health and emergency management as they guide communities in responding to and recovering from disasters.
The compendium offers an easy-to-navigate, comprehensive, web-based repository of HHS products, services and capabilities available to state, state, tribal, territorial, and local agencies before, during, and after public health and medical incidents. The information spans 24 categories, and each category showcases the relevant disaster resources available from HHS and partner agencies, a brief description of each resource and information on accessing each one. Categories range from patient movement to hospital care and from situational awareness to decontamination. Resources include platforms such as GeoHEALTH and the HHS emPOWER Map that use Geographic Information System capabilities to support health response as well as consultation services, such as emergency planning, disease surveillance and tracking, and food, drug and device safety. Resources also include personnel, such as medical staff from the U.S. Public Health Service and National Disaster Medical System who can deploy to communities to augment local hospital, shelter or public health staff. The compendium will be updated regularly and expanded as federal agencies add products, capabilities and services to help communities prepare for, respond to, and recover from the health impacts of disasters.
