2017 MEDLINE Data Changes

MeSH vocabulary has been updated for 2017. The MeSH Browser currently points to the 2017 MeSH vocabulary with a link to the 2016 MeSH Vocabulary. Searchers should consult the Browser to find MeSH headings of interest and their relationships to other headings. The Browser contains MeSH heading records that may include Scope Notes, Annotations, Entry Terms, History Notes, Allowable Qualifiers (Subheadings), Previous Indexing, and other information. It also includes Subheading records and Supplementary Concept Records (SCRs) for substances and diseases that are not MeSH headings. MEDLINE records with updated MeSH are anticipated to be in PubMed in mid-December 2016. This year 77 MeSH headings were either changed or deleted and replaced with more up-to-date terminology, and 629 new MeSH headings, including two new Publication Types, were added to MeSH in 2017. In order to improve indexing consistency and efficiency and to make MEDLINE searching easier and more straightforward, a new subheading, “diagnostic imaging,” was added. It replaces three existing subheadings; “radiography,” “radionuclide imaging,” and “ultrasonography.” For an overview of the many other 2017 MEDLINE data changes, visit the NLM Technical Bulletin.

Cataloging and Metadata News from NLM

Starting with 2017, the NLM Classification will be moving from an annual spring update to twice-yearly updates. The winter version, to be published in mid-to-late January, will encompass changes to the NLM Classification resulting from new and changed Medical Subject Headings (MeSH) terms for 2017 as well as additional minor updates to the index. The summer version, to be published in mid-to-late August, will encompass the ongoing systematic review of particular classification schedules and other miscellaneous updates. The Index to the NLM Classification will reflect 2017 MeSH changes when the 2017 Winter version of the NLM Classification is published in January 2017. This update will be available four months earlier than in the past.

The National Library of Medicine (NLM) adopted the 2017 MeSH vocabulary for cataloging on November 21, 2016. Accordingly, MeSH subject headings in LocatorPlus were changed to reflect the 2017 MeSH vocabulary and appear in that form as of November 21, 2016. When year-end processing (YEP) activities are completed in mid-December, the NLM Catalog database and translation tables will be updated to reflect 2017 MeSH. Until then, there will be a hiatus in the addition of new and edited bibliographic records to the NLM Catalog.

The subheading “Calendars” and “Study Guide.” They will not be used by MEDLINE indexers. For additional information, visit the NLM Technical Bulletin.

New Web-Based Broadband Health Mapping Tool!

The Federal Communications Commission’s Connect2Health Task Force recently launched the Mapping Broadband Health in America tool, a web-based mapping tool that enables more efficient, data-driven decision making at the intersection of broadband and health. By allowing users to ask and answer questions about broadband and health at the county and census block levels, the tool provides critical data that can help drive broadband health policies and connected health solutions for this critical space. The mapping tool is an interactive experience, showing various aspects of connectivity and health for every state and county in the United States. Users can generate customized maps that display broadband access, adoption and speed data alongside various health measures (e.g., obesity, diabetes, disabilities and physician access) in urban and rural areas. These maps can be used by both public and private sectors and local communities to identify not only gaps, but also opportunities. Also released with the mapping platform are the Priority 100 and Rural 100 lists, identifying counties that have critical needs in broadband and health. Priority 100 is a list of the 100 counties nationwide with the greatest broadband and connectivity needs and populations of at least 25,000. Rural 100 is similar to Priority 100, but only includes rural areas with a population of 15,000 or more. Additional information is available in the Press Kit.

On November 10, 11:00am-12:00pm PST, the FCC’s Connect2Health Task Force and the Consumer and Governmental Affairs Bureau’s Office of Intergovernmental Affairs will jointly host a free webinar to further explain and explore this new tool, Mapping Connected Health County by County. The session will focus on how state and local government offices, agencies and other local community stakeholders can effectively use the Mapping Broadband Health in America platform. Key audiences for the webinar include federal, state and local agencies and offices that address health, connectivity, technology and/or rural development; such as county health departments, public health officers and epidemiologists, broadband and technology officers, data analytics and GIS teams, and community health workers and strategists.

NLM Announces the Addition of the Louis Sokoloff Papers to Profiles in Science

Louis Sokoloff (1921-2015) was an American physician and neuroscientist whose innovative research methods and tools transformed the study of brain structure and function. During nearly six decades at the National Institute of Mental Health, he developed new experimental methods, combining techniques and mathematical descriptions from biochemistry, enzyme kinetics, and physiological studies to accurately measure cerebral blood flow and metabolism. Using radioactive 2-deoxyglucose tracers, he was able to make real-time images of living animal brains under various physiological conditions, showing which brain regions were most active at a given moment. This work, which definitively linked regional metabolic activity to particular brain functions, constituted a quantum leap for brain-mapping research. It was also rapidly adapted to positron emission tomography (PET) scanning technology, which soon became essential for studying and diagnosing brain disorders and many types of cancer. He received a Lasker Award in 1981 in recognition of this important “bench-to-bedside” translational research.

Now available from the National Library of Medicine is a selection from the papers of Dr. Sokoloff, on the National Library of Medicine’s Profiles in Science® Web site. Profiles in Science is a digital project of the Library that provides online access to archival collections of twentieth- and twenty-first century leaders in science, medicine, and public health. The Louis Sokoloff Papers Profiles in Science site features correspondence, published articles, interviews, and photographs from the Louis Sokoloff Papers held by NLM. Visitors to Profiles in Science can view, for example, photos from Sokoloff’s childhood and early career, correspondence with colleagues and students, and experimental brain images produced with the tracers he developed. An in-depth historical narrative leads to a wide range of primary source materials that provide a window into Sokoloff’s life and major contributions to neuroscience.  Visitors may also view a brief chronology of Sokoloff’s life, a glossary of terms specific to the collection, and a further readings page, as well as search and browse the collection.
