MEDLINE/PubMed Year-End Processing Activities During Fall 2015

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.

Important Dates

  • 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 PubMed Link: “Articles Frequently Viewed Together”

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.

NLM Hosting 2015 DailyMed/RxNorm Jamboree Workshop on September 24!

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.

Toxicology and Environmental Health Highlight: Developmental and Reproductive Toxicology (DART)

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.

HHS Unveils First Compendium of Resources for Health Emergencies

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.

NLM Digitizes Unique Early English Books, Allowing Free Online Access

Robert Burton’s The Anatomy of Melancholy (London: Printed for John Garway, 1660).The National Library of Medicine (NLM) announces the release through its Digital Collections of nearly 200 items uniquely held by the NLM and printed in the English-speaking world from 1552 to 1800. NLM’s participation in the English Short Title Catalog (ESTC) helped staff identify the uniqueness of these items. The ESTC is a union catalog managed by the British Library which lists books, pamphlets, and other ephemeral material printed in English-speaking countries from 1473 to 1800, containing over 480,000 items reported by over 2,000 libraries from around the world, including the NLM, British Library, Folger Shakespeare Library, and Library of Congress. The NLM holds over 9,000 ESTC items, the most for any medical library in the world.

The NLM’s new digital collection of unique English short titles includes:

As with all printed material added to NLM’s Digital Collections, these items will be included in the Internet Archive generally, and as part of the Medical Heritage Library, an international collaboration which the NLM has supported since 2010 to provide free access to historical medical literature.

The NLM’s Digital Collections currently encompass over 14,000 items spanning eight centuries and including monographs, serials, videos, and ephemeral literature. It complements PubMed Central® (PMC), NLM’s free, full-text archive of biomedical and life sciences journal literature, now including 3.5 million articles spanning the early nineteenth-century to the present day. Additionally, as part of its ongoing initiative to make its historical collections widely known and available, the NLM also announces a three-year cooperation with the University of St. Andrews to identify and preserve the rarest European materials in the NLM’s historical collections. The University of St. Andrews hosts the Universal Short Title Catalog (USTC), funded by the Andrew J. Mellon Foundation. The USTC is a unique collective database which seeks to include all books published in Europe between the invention of printing and the end of the sixteenth century.

Climate Change and the Health of Americans: Information Resources from NLM

The July 2015 issue of The Nation’s Health features a cover story on the link between climate change and health, new U.S. government initiatives aimed at protecting communities from the health impacts of climate change, and the effort to reframe climate change as an urgent public health issue. These initiatives are meant to help Americans understand climate change as not just an environmental issue, but also an important health issue.

The National Library of Medicine (NLM) provides many sources of information to assist health professionals with the knowledge and resources they need to assess who is most vulnerable to the health effects of climate change, and teach patients how to minimize the impacts. The Division of Specialized Information Services (SIS) Arctic Health website is a central source for information on diverse aspects of the Arctic environment and the health of northern peoples. The site gives access to evaluated health information from hundreds of local, state, national, and international agencies, as well as from professional societies and universities. For example, the Arctic Health Climate Change page provides links to websites, publications, and multimedia presentations covering the impacts of climate change on the health, activities, and well-being of people in the Arctic. It includes climate-change observations from both the scientific-research and the traditional-knowledge points of view.

The SIS Environmental Health and Toxicology website features Enviro-Health Links – Climate Change and Human Health. This page provides a wealth of environmental health-related web resources from the U.S. government and other trusted sources focused on climate change and health. Resources include links to information about specific impacts on agriculture, extreme weather, general health, infectious disease, population displacement, preparedness and security, and water quality and scarcity. In addition to topic-related searches of NLM resources, the page offers overview materials, glossaries, information on law, policy, and regulation, links to blogs, news, podcasts and video, and educational material such as the NLM’s Environmental Health Student Portal.
