A new Web page, <a href="/bsd/policy/yep_activities.html">National Library of Medicine (NLM) Annual MEDLINE/PubMed Year-End Processing Activities</a>, provides background and examples about the typical changes that take place for MEDLINE citations during year-end processing.

<h2>MeSH<span class="registered">®</span> Vocabulary Updated for 2007</h2>
|
|
|
|
<p>
|
|
The <a href="//www.nlm.nih.gov/mesh/MBrowser.html">MeSH Browser</a> currently contains a link to the 2007 MeSH vocabulary. Searchers should consult the Browser to find MeSH headings of interest and to see these in relationship to other headings. The Browser contains MeSH Headings records that may include scope notes, annotations, entry terms, history notes, allowable qualifiers (subheadings), previous headings and other information. It also includes Subheading records and Supplementary Concept Records (SCRs) for substances that are not MeSH Headings. </p>
|
|
|
|
<p>
|
|
For highlights about 2007 MeSH see the article, <a href="//www.nlm.nih.gov/pubs/techbull/nd06/nd06_mesh.html"><em>What's New for 2007 MeSH</em></a>, in this issue of the <em>NLM Technical Bulletin</em>.
|
|
</p>
|
|
|
|
<p>
|
|
PubMed's MeSH database and translation tables will be updated to reflect 2007 MeSH in mid-December when end-of-year activities are complete and the newly maintained MEDLINE data are available in PubMed.
|
|
</p>
|
|
|
|
<h2>Updated MeSH in MEDLINE Citations</h2>
|
|
|
|
<p>
|
|
MEDLINE citations with updated MeSH should be in PubMed in mid-December 2006. See the <a href="//www.ncbi.nlm.nih.gov/books/NBK3827/#pubmedhelp.How_can_I_save_my_re">Changing a saved search</a> section in PubMed Help for details on revising My NCBI stored searches.
|
|
|
|
</p>
|
|
|
|
<p>
|
|
The <a href="//www.nlm.nih.gov/mesh/">MeSH Section homepage</a> provide links to descriptions of the different types of MeSH maintenance applied to MEDLINE citations. In addition to the information found in the <a href="https://www.nlm.nih.gov/mesh/introduction.html">Introduction</a> to MeSH, the About Updates link under the "MEDLINE Citation Maintenance" section explains how NLM prepares the changes in a machine-readable form for others to use. To access the XML files for the tasks processed for this maintenance, click on the "Download XML Files" link under this same section. This information is helpful for those individuals or organizations who apply MeSH headings to their own application (such as indexing curricula guides) and want to keep those applications up-to-date with the new year of MeSH.
|
|
</p>
|
|
|
|
|
|
<h2>New MeSH Headings</h2>
|
|
|
|
<p>
|
|
This year 494 new MeSH Headings were added.
|
|
</p>
|
|
|
|
<p>
|
|
Typically, NLM does not retrospectively re-index MEDLINE citations with new MeSH Headings. Therefore, searching for a new MeSH term tagged with [mh] or [majr] effectively limits retrieval to citations indexed after the term was introduced. PubMed's Automatic Term Mapping (ATM) expands an untagged subject search to include both MeSH Term and Text Word(s), and may retrieve relevant citations indexed before the introduction of a new MeSH term.
|
|
</p>
|
|
|
|
|
|
<p>
|
|
|
|
A notable exception this year to the general rule of not retrospectively re-indexing MEDLINE citations with brand new concepts is Papillomavirus Vaccines, a new 2007 Category D heading shown below. The scientific importance of this topic prompted NLM to add this new heading to existing citations. Searching on Papillomavirus Vaccines will, therefore, retrieve citations indexed before the implementation of 2007 MeSH even though the History Note in the 2007 MeSH Browser shows 2007 as the date of introduction for this concept.
|
|
</p>
|
|
|
|
|
|
<h2>Brand New Concepts</h2>

<h2>Changes to MeSH Headings</h2>
|
|
|
|
<p>
|
|
This year, 120 MeSH Headings were either changed or deleted and replaced with more up-to-date terminology. During year-end processing, NLM updates MeSH headings on the MEDLINE citations.
|
|
</p>
|
|
|
|
<p>
|
|
In addition to the replaced-by heading changes, year-end processing includes adjustments to MEDLINE citations to reflect 2007 MeSH vocabulary and to enhance search retrieval. These follow-on adjustments are largely the adding of more MeSH headings or Supplementary Concept Record Names of Substances (NM) to help searchers refine retrieval. In some cases, the changes clarify areas where a single concept existed before, but it is now represented by two or more specific concepts. Some examples follow.
|
|
</p>
|
|
|
|
<p>
|
|
|
|
These types of changes suggest the importance of routinely using PubMed's Details feature when searching to see how terms are mapped in the new year's vocabulary and then checking the MeSH Browser or PubMed's MeSH database for clarification.
|
|
</p>
|
|
|
|
|
|
<p><strong>Replaced heading; old heading deleted and not retained as entry term to new heading; adjustments to search strategies needed; further adjustments made to existing citations</strong></p>
|
|
|
|
|
|
|
|
<dl>
|
|
<dt><em>Example:</em></dt>
|
|
<dt>In 2006 MeSH, the term Urogenital Diseases was in two trees under:</dt>
|
|
|
|
<dd>Urologic and Male Genital Diseases</dd>
|
|
<dd>Female Genital Diseases and Pregnancy Complications</dd>
|
|
</dl>
|
|
|
|
<dl>
|
|
<dt>In 2007 MeSH, the term Urogenital Diseases was deleted and replaced with:</dt>
|
|
|
|
<dd>Female Urogenital Diseases</dd>
|
|
</dl>
|
|
|
|
<dl><dt>The term Urologic and Male Genital Diseases was replaced with:</dt>
|
|
<dd>Male Urogenital Diseases</dd>
|
|
</dl>
|
|
|
|
<p>Citations previously indexed with Urogenital Diseases will be globally maintained to have this term replaced with the term Female Urogenital Diseases. Therefore, NLM will be processing additional tasks to insure that the citations properly have the correct MeSH heading Female Urogenital Diseases and/or Male Urogenital Diseases on them.</p>
|
|
|
|
|
|
|
|
<p><em>Example:</em><br />
|
|
In 2007 MeSH, Tampons is being replaced with the heading Tampons, Surgical. Citations indexed to Tampons will get this new heading. NLM will be processing follow-up tasks to insure that citations which were related to Menstrual Hygiene Products will get that appropriate heading rather than the Tampons, Surgical heading.</p>
|
|
|
|
|
|
<p><strong>Replaced heading; old heading deleted and not retained as entry term to new heading; adjustments to search strategies needed; no further adjustments made to existing citations beyond the replaced headings</strong></p>

<h2>Entry Combination Revisions</h2>
|
|
|
|
<p>
|
|
This year during year-end processing, NLM will again retrospectively replace certain MeSH heading/subheading combinations, known as entry combinations, with the appropriate precoordinated MeSH heading or other MeSH heading/subheading combination in MEDLINE citations. Searchers who get zero retrieval for a MeSH Heading/subheading combination may want to check the 2007 MeSH Browser for the heading to see if the Entry Combination information indicates a different term.
|
|
</p>
|
|
|

<h2>Heading Mapped-To (HM) Maintenance</h2>
|
|
|
|
<p>
|
|
This year NLM will again perform maintenance to add the current HM value as a MeSH Heading for every SCR (Supplementary Concept Record) Name of Substance in a MEDLINE citation, whenever that MeSH Heading is absent. For more information on Heading Mapped-to Maintenance, please see the article, <a href="//www.nlm.nih.gov/pubs/techbull/nd03/nd03_map_to.html"><em>Heading Mapped-to Maintenance: for Supplementary Concept Records' Names of Substance. NLM Tech Bull. 2003 Nov-Dec;(335):e4.</em></a>
|
|
</p>
|
|
|
|
<h2>EC/RN Numbers (RN) and Name of Substance (NM)</h2>
|
|
|
|
<p>
|
|
Changes in 2007 MeSH also include Enzyme Commission (EC) Nomenclature and Chemical Abstracts Service (CAS) Registry Number data, including Substance Name (NM). These not only affect the MeSH chemical concepts in Category D, but the Supplementary Concept Records as well. The corresponding changes will be made to the MEDLINE citations during year-end processing.
|
|
</p>
|
|
|
|
<h2>Supplementary Concept Records (SCRs) Elevated to MeSH Headings</h2>
|
|
|
|
<p>
|
|
For general information on SCRs elevated to MeSH heading status, see the article <a href="//www.nlm.nih.gov/pubs/techbull/nd01/nd01_mesh_chemical.html"><em>Changes in the Treatment of Chemical Data in MEDLINE<span class="registered">®</span> Citations. NLM Tech Bull. 2001 Nov-Dec;(323):e7.</em></a> Some of the 494 new MeSH headings previously existed as an SCR. This means the current form of the preferred MeSH Heading was introduced for 2007 MeSH, but the concept has been in the MeSH vocabulary since an earlier year and the current MeSH Heading will retrieve citations back through the period of time during which indexers originally assigned the concept as an SCR.
|
|
</p>
|
|
|
|
<h2>Pharmacological Action (PA)</h2>
|
|
|
|
<p>
|
|
As a reminder, NLM policy, effective August 2002, calls for adding Pharmacological Action terms to new or existing Supplementary Concept Records in the MeSH Browser if the following three criteria are met:
|
|
</p>
|
|
|
|
|
|
|
|
<ul>
|
|
<li>There are more than 20 citations in PubMed discussing the Pharmacological Action being exhibited by that drug;</li>
|
|
<li>There is substantial evidence that the Pharmacological Action is in effect in humans (i.e., the drug is used clinically); and </li>
|
|
<li>A reasonable proportion of the literature (greater than or equal to 10%) on that drug accounts for those effects. </li>
|
|
</ul>
|
|
|
|
|
|
<br />
|
|
|
|
|
|
<p>
|
|
Please see the article <a href="//www.nlm.nih.gov?pubs/techbull/ja03/ja03_papx.html"><em>Pharmacologic Action Headings: PubMed. NLM Tech Bull. 2003 Jul-Aug;(333):e6.</em></a> which describes Pharmacologic Action terms. If you enter a MeSH Term that is also a Pharmacologic Action Term, PubMed will search the term as [MH], [PA], or [TW], e.g., platelet aggregation inhibitors will automatically map to: platelet aggregation inhibitors [mh] OR platelet aggregation inhibitors [pa] OR platelet aggregation inhibitors [tw].

<h2>Additional Changes to MEDLINE and OLDMEDLINE Data</h2>
|
|
|
|
<br />
|
|
|
|
<p><strong>1. <a href="//www.nlm.nih.gov/pubs/techbull/so06/so06_oldmedline_status.html">OLDMEDLINE Status change</a></strong>
|
|
</p>
|
|
|
|
<p>
|
|
|
|
There are two changes. First the status tag [PubMed - OLDMEDLINE for pre1966] will be simplified to [PubMed - OLDMEDLINE]. The second change is for those OLDMEDLINE citations which have had their <a href="//www.nlm.nih.gov/pubs/techbull/nd05/nd05_technote.html#15">Old Term keyword mapping to MeSH completed</a>, the PubMed citation status will be changed from [PubMed - OLDMEDLINE] to [PubMed - indexed for MEDLINE]. These records will be retrieved when limiting to the MEDLINE subset, or when searching medline [sb]. Searchers not interested in these older citations are advised to restrict their searches using the date range function within the Limits feature, or to set up a filter for publication date.
|
|
</p>
|
|
|
|
<p><strong>2. Partial Retraction notations </strong></p>
|
|
|
|
<p>
|
|
NLM is adding two fields to the MEDLINE citation: Partial retraction in and Partial retraction of. These fields are established as a means of distinguishing between a journal article that is retracted in whole (reflected by the use of the already existing Retraction of and Retraction in elements) versus one that is retracted in part (e.g., a cell line was contaminated but that didn't affect all results/conclusions of the paper). Partial retraction of contains the bibliographic reference of an article being partially retracted, and is present in the citation for the notice of partial retraction. Partial retraction in contains the bibliographic reference of the notice of partial retraction, and is present in the citation for the original paper.
|
|
</p>
|
|
|
|
<p>
|
|
Beginning in December 2006 NLM will begin to cite partial retractions. Older citations may be edited to use these new fields.

<p><strong>3. Full Journal Title format change in MEDLINE citations</strong></p>
|
|
|
|
<p>
|
|
Some MEDLINE journal titles contain the general material designation (GMD), within brackets, as a part of the full journal title. NLM is removing the bracketed GMD from the journal titles during year-end processing. However, you may find this change reflected on some citations before the new system is available in mid-December. Generally this designation is the value [electronic resource]. With so many journals now available online the qualifier is not necessary for the journal title display. Ending periods are also being removed.
|
|
</p>
|
|
|
|
<p>
|
|
The following example shows how a full journal title with a GMD currently looks in the MEDLINE display in PubMed:
|
|
<br /><br />
|
|
|
|
JT — <em>BMC bioinformatics [electronic resource].</em> </p>
|
|
|
|
<p>
|
|
After the title has been revised it will look like this:<br /><br />
|
|
|
|
JT — <em>BMC bioinformatics</em>
|
|
|
|
</p>
|
|
|
|
|
|
<p>
|
|
The full journal title display in the Journals database will also change. </p>
