> Additional news:
> re PubMed: 'From November 28 - A new search filter, Systematic Reviews, is
> now available on PubMed's Clinical Queries screen. This filter retrieves
> citations for systematic reviews, meta-analyses, reviews of clinical
> trials, evidence-based medicine, consensus development conferences,
> guidelines, and citations to articles from journals specializing in
> clinical review studies.' Of course, this won't necessarily match
> everyone's definition of what a 'systematic review' should contain.
>
> re BL Medline training
> This won't take place at BL anymore. Discussions are ongoing re them
> continuing elsewhere- the BL Medline page
> (http://www.bl.uk/services/information/blmedline.html) will include
> information once available.

>
> Clinical Advisory issued by the National Eye Institute
>
> Following nationwide trials it seems that high levels of antioxidants and
> zinc significantly reduce the risk of advanced age-related macular
> degeneration and its associated loss of vision. The trials also revealed
> that the same nutrients had no significant effect on the development or
> progression of cataracts. More details relating to the trial results can
> be found in the October issue (volume 119 part 10) of the Archives of
> Opthalmology
>
> Events of 11th September 2001 and bioterrorism
>
> The National Library of Medicine Index section has recently issued
> guidelines to indexers on the method of indexing Medline citations about
> this event and it was felt that these same guidelines might be of
> assistance to searchers looking for information on these topics. The
> guidelines are set out below
>
> Citations to articles about the plane crashes will be indexed with
> thefollowing
> Medical Subject Heading (MeSH®) descriptors:
> Terrorism and Aircraft and
> New York City or Virginia or Pennsylvania
>
> If rescue operations are discussed in the article, the
> MeSH descriptors
> Disasters or Rescue Work may also be assigned to the
> citation.
>
> If the article discusses identifying the casualties,
> Forensic Anthropology will be
> assigned to the citation. (Human Identification is an
> entry term (a see reference)
> to the MeSH descriptor Forensic Anthropology.) If DNA
> fingerprinting
> techniques are used to identify the remains, the MeSH
> descriptor DNA
> Fingerprinting will be assigned to the citation.
>
> Citations to articles about the psychological effects of
> September 11th and later
> events on persons other than victims will be indexed
> with the following MeSH
> descriptors:
> Terrorism or Bioterrorism and
> Stress, Psychological
>
> Articles discussing the victims' families may be indexed
> with Life Change
> Events. (Stressful Events is an entry term (a see
> reference) to the MeSH
> descriptor Life Change Events.
>
> Citations to articles about recent anthrax incidents
> will be indexed with the
> following MeSH descriptors:
> Bioterrorism and
> Anthrax
>
> If the anthrax transmission is discussed, the subheading
> transmission will be
> coordinated with the Anthrax descriptor (i.e.,
> Anthrax/transmission).
>
> Citations to articles about inhalation or pulmonary
> anthrax will be indexed with
> the following MeSH descriptors:
> Anthrax and
> Respiratory Tract Infections
>
> Citations to articles about cutaneous or skin anthrax
> will be indexed with the
> following MeSH descriptors:
> Anthrax and
> Skin Diseases, Bacterial
>
> The causative organism will be indexed as:
> Bacillus Anthracis and
> Spores, Bacterial
>
> If the article is about the detection or demonstration
> of these spores in offices or
> post offices, the subheading isolation & purification
> will be coordinated with the
> organism (i.e., Bacillus Anthracis/isolation &
> purification). The MeSH
> descriptors Postal Service, Occupational Exposure or
> Occupational
> Diseases may also be used, when appropriate.
>
> Closure of the Congressional offices will be indexed
> with Government
> Agencies coordinated with the appropriate geographic
> term.
>
> Citations to articles about other forms of possible
> bioterrorism will be indexed
> under the disease and Bioterrorism (e.g., Smallpox and
> Bioterrorism). If the
> article discusses a particular organism, its MeSH
> descriptor will also be used
> (e.g., Variola virus).
>
> History of Medicine subset
>
> The new History of Medicine subset which is a joint project between the
> National Library of Medicine's History of Medicine and Bibliographic
> Services Divisions and the National Center for Biotechnology Information
> is now up and running. It can be accessed via the pull-down menu on the
> PubMed Limits screen.
>
> If required the subset can be used in a search as history [sb] eg
> anthrax AND history [sb]
>
> Searchable online books linked to PubMed
>
> The National Center for Biotechnology Information latest project is called
> Bookshelf and is a growing collection of biomedical textbooks assembled in
> collaboration with book publishers. Access to books currently available
> is via the Bookshelf logo on PubMed or the Books heading on the sidebar of
> the National Center for Biotechnology Information home page. From the
> Bookshelf home page the table of contents for each item can be viewed by
> clicking on the books' cover. Type a search term in the query box and the
> results appear as a list of books in which the term has been found and
> with the number of book sections having the term indicated as a hyperlink.
> From the total number of 'hits' it is possible to obtain a list of the
> sections containing the term and from thereon to figures and tables etc.
>
> Another way to access Bookshelf is via hyperlinked phrases in PubMed
> abstracts. Terms or phrases can be displayed as hyperlinks. These
> hyperlinked phrases are useful, among other things, in providing
> background information to research article abstracts thus assisting
> researchers to take a cross-disciplinary approach.
>
> The amount of access to each book varies from publisher to publisher but
> all are providing the full content, including figures and tables, free of
> charge and without a password requirement.
>
> Changes in the treatment of chemical data in Medline
>
> To make chemical searching in Medline more consistent NLM has implemented
> two changes.
>
> The first relates to Medline citations from 1966 to 1980 with a MeSH
> Category D (Chemical) descriptor which now has an associated RN (CAS
> Registry/EC Number) field with the number and name of the substance (NM).
> For Category D descriptors that name a group or class of compounds rather
> than an individual chemical, the RN's are zero.
>
> The second change relates to Supplementary Concept Records (SCR) created
> since mid 1980 that have been promoted to MeSH heading (MH) descriptor
> status, the MH having been retrospectively added to the relevant Medline
> citations. Prior to promotion to MH status only the RN/NM field for the
> specific chemical appeared on the citations. An MH occurrence for the
> heading the SCR mapped to was, and still is, on the citation. However,
> the MH that the SCR mapped to was likely a broader concept and therefore a
> different descriptor.
>
> These changes will enable Medline users to undertake comprehensive
> searches as far back as 1966 using RN or NM for MH status concepts.
> Furthermore an MH search will retrieve records from the time the chemical
> was introduced as an SCR without the need to include RN or NH in the
> search strategy.
>
> The History Note data in the MeSH Vocabulary File have not been updated to
> reflect the change in policy for the SCR's that have been elevated to MH
> status. The current history notes, while not wrong, do not account for
> the change in policy.
>
> Finally, if an RN search fails then try a name search. It would be
> advisable to qualify the name search with (NM) which would retrieve
> chemicals that are SCR's and not MeSH descriptors.
>
> MeSH 2002 files now available for downloading
>
> The 2002 version of the MeSH vocabulary in ASCII and XML format may now be
> downloaded free of charge from http://www.nlm.nih.gov/mesh/filelist.html
>
> The available files are:-
>
> 1) XML and ASCII MeSH containing complete records for all descriptor,
> subheading and supplementary concept records. These files are updated
> periodically. Current plans suggest a weekly update, usually involving
> only supplementary concept records.
>
> 2) MeSH Trees containing descriptors with their associated hierarchical
> tree numbers, sorted by tree numbers, subheadings and supplementary
> concept records are not included.
>
> 3) MeSH in MARC-compatible format which contains MeSH headings,
> subheadings and combination MeSH heading/subheading records in
> MARC-compatible format. Supplementary concept records are not included.
>
> 4) Pharmacological Action Lists 2002 containing pharmacologic actions
> of a given drug and drugs with a given pharmacologic action.
>
> National Heart, Lung and Blood Institute
>
> The NHLBI has issued a new Clinical Advisory relating to women with the
> rare lung disease lymphangioleiomyomatosis (known as LAM)
>
> The advisory entitled "Women with rare lung disease found to also to have
> high prevalence of meningiomas, first study to document tumor connection;
> possible hormonal cause".
>
> Details of the study can be found in the October 17th issue of the Journal
> of the American Medical Association - JAMA 2001 October 17 volume 286 part
> 15 pages 1879-81.
>
> Smallpox preparedness
>
> The National Library of Medicine is working with the Center for Disease
> Control and Prevention to make full text information on diagnosis and
> treatment of smallpox available on the Web.
>
> The "Smallpox and vaccinia" chapter from Vaccines was recently added to
> the NLM's/NCBI's Bookshelf (referred to in an earlier article) at
> http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=Books
>
> Publisher permission is being sought to create full text versions of many
> of the important bibliographic references in the "Smallpox and vaccina"
> chapter. Links to full text will be available from the chapters
> references section and from the corresponding Medline/PubMed of
> Locatorplus records.
>
> Similar efforts are underway for selected references in "Smallpox and its
> eradication" which is available in full text at
> http://www.who.int/emc/diseases/smallpox/Smallpoxeradication.html
>
> More information on bioterrorism preparedness can be located at
> http://www.bt.cdc.gov/
>
> Whats new in MeSH for 2002
>
> There have been a number of changes in the 2002 edition of MeSH. Lists of
> all the new, deleted or replaced descriptors can be found on the MeSH
> website.
>
> Changes of particular importance relate to Viruses, Complementary and
> Alternative Medicine, Plants and Phytotherapy, Bioethics and Transport and
> Carrier Proteins.
>
> MeSH vocabulary changes necessitate a review of PubMed Cubby stored
> searches
>
> Following the MeSH amendments for 2002 it is advisable for searchers to
> review their Cubby stored search strategies.
>
> Having reviewed and added or deleted any terms the search strategy can be
> amended by following the method shown in this example
>
> Note: Cubby Stored Searches cannot be edited. These instructions
> explain
> how to revise a strategy, re-store it, and also how to
> delete the old strategy.
>
> Example scenario: A user has a Cubby Stored Search for
> "confidentiality." In
> reviewing the list of new headings, she sees that Genetic
> Privacy is a new
> MeSH term for 2002. She wants to edit her stored search to
> include this term.
>
> Step 1.
> Link to the Cubby (from the sidebar).
>
> Step 2.
> Log in to the Cubby, if not already logged in.
>
> Step 3.
> Click on the name of the stored search you want to revise
>
> Step 4.
> On the Stored Search Information Screen, click on the
> Search button
>
> This will run the search without updating it and display
> the Search Results
> page. The strategy for the stored search displays in the
> query box with the
> search results.
>
> Step 5.
> You can now edit the search strategy directly in the query
> box on the Search
> Results page. You may have to use the arrow keys to get to
> the part of the
> strategy that you want to edit.
>
> Step 6.
> When you have completed revising your strategy, run the
> search with the Go
> button.
>
> Step 7.
> Click on the Cubby link on the sidebar.
>
> Step 8.
> The search will be forwarded to the Cubby. Edit the search
> name if you wish.
> (You may use the same name as before.) Click on the Store
> in Cubby button.
>
> Step 9.
> Delete the old stored search. To do this, click in the box
> next to the name and
> click the Delete Selected Searches button
>
> Step 10.
> The revised Cubby Stored Searches can be updated as in the
> past
>
> Name changes for PubMed fields
>
> The National Center for Biotechnology Information (NCBI)
> has decided to
> standardize the names of fields for the Entrez databases,
> including PubMed. The
> following changes for field names have been made on the
> pull-down menu on
> the Preview/Index screen and also the Fields pull-down menu
> on the Limits
> screen.
>
> Old field name New field name
>
> Author name Author
> Journal name Journal
> Page number Pagination
> Subheading MeSH
> Subheading
> Title word Title
> Title/Abstract word Title/Abstract
>
> These new field names have been added as search tags. (Old
> search tags remain
> in use.) No changes have been made to the display tags
> used in the Medline and
> XML formats.
>
> PubMed's Help has been revised to use the new field tag
> names.

> Locatorplus is now using 2002 MeSH
>
> As of December 10, 2001, the National Library of Medicine
> (NLM)
> adopted the 2002 MeSH vocabulary for cataloging and for
> records being
> created by collaborating data producers. MeSH subject
> terms in Locatorplus,
> were changed to reflect 2002 MeSH
>
> All MeSH 2002 changes are reflected in the bibliographic
> records in
> Locatorplus, which are also accessed via the NLM Gateway.
>
> Use MeSH 2002 when searching for books, journals,
> audiovisuals, or other
> resources by MeSH subject in Locatorplus or in the NLM
> Gateway.
>
> MeSH 2002 is the subject vocabulary for headings in
> Locatorplus in the
> following fields of the bibliographic records:
>
> MARC21 Field
> Contains:
>
> 650 Main headings or main headings and

>
> MEDLINE data changes 2002
>
> Significant changes have been made this year which are detailed briefly
> below -
>
> The annual update to Medical Subject Headings (MeSH®),
> NLM's
> controlled vocabulary used for subject indexing and
> retrieval
> Updated MeSH in MEDLINE citations to reflect changes
> in MeSH
> vocabulary
> New Author Name indexing policy
> Other indexing policy changes
> Other changes to data in MEDLINE citations including
> EC/RN,
> Publication Type, Title Abbreviation and ISSN
> information
>
> Annual Update to Medical Subject Headings: 2002 MeSH
> The MeSH Section's MeSH Browser currently contains 2001
> MeSH with a
> link to a version with the 2002 MeSH. Searchers should
> consult the MeSH
> Section's MeSH Browser to find descriptors of interest and
> to see these in
> relationship to other descriptors. The Browser displays
> virtually complete
> MeSH records, including the scope notes, annotations, entry
> vocabulary,
> history notes, allowable qualifiers (subheadings), etc. It
> also provides links to
> relevant sections of the NLM Indexing Manual.
>
> It is expected that PubMed's MeSH Browser and translation
> tables will be
> updated to reflect 2002 MeSH in January when end-of-year
> activities are
> complete and the newly maintained MEDLINE is available via
> PubMed.
>
> Updated MeSH in MEDLINE Citations
>
> Changes to MeSH Terms
> During year-end processing, all MeSH Terms in MEDLINE
> citations are
> updated to reflect changes in 2002 MeSH. These changes
> are expected
> in PubMed by January.
>
> New MeSH Terms
> Eight hundred and forty-seven (847) new MeSH Subject
> Headings have
> been introduced in 2002 MeSH. The new MeSH terms may
> begin to appear on MEDLINE
> citations by January.
>
> Please note that there are several new food
> hypersensitivity terms, new disease headings
> and new organism-specific proteins
>
> Generally, NLM does not retrospectively index MEDLINE
> citations with
> new MeSH Headings. Therefore, searching for a new MeSH
> Term
> qualified as [MeSH Term] or [Major MeSH Topic]
> effectively limits
> retrieval to citations indexed after the term was
> introduced. An
> unqualified subject search in PubMed expands a search
> by including both
> MeSH Term and Text Words, and may retrieve relevant
> citations
> indexed before the introduction of a new MeSH Term.
>
>
> Other MeSH Changes
> All citations indexed prior to the 2002 indexing year
> with a specific term
> in the Plants, Toxic tree (B06.660) or the Plants,
> Medicinal tree
> (B06.560) will have their parent heading (i.e.,
> Plants, Toxic or Plants,
> Medicinal) added retrospectively. For example, any
> citation indexed with
> the MeSH heading, Garlic, will have the MeSH heading
> Plants,
> Medicinal added if it is not already present in the
> citation.
>
> All indentations of specific plant names have been
> removed from these
> two trees for 2002 MeSH. Indexers will now coordinate
> index when
> these aspects are important to the article. Now that
> these two trees no longer
> explode, adding the parent heading to the citation for
> retrospective data and using
> coordinate indexing for 2002 forward provides the same
> retrieval
> capability that explosion did.
>
> NLM has been able to do some verification of various
> entry combinations.and this
> year has replaced the illegal MH/SH combinations on
> older citations with the legal,
> precoordinated MeSH heading (e.g., the illegal
> combination Aorta/radiography
> was changed to Aortagraphy).
>
> The MeSH heading Coronavirus, Human was deleted and
> all
> occurrences of that term were replaced by the MeSH
> heading, Coronavirus.
> Where appropriate, the new MeSH headings Coronavirus
> 229E,
> Human and/or Coronavirus OC43, Human were added to
> citations.
>
> The MeSH heading Diarrhea Virus, Bovine Viral was
> deleted and all
> occurrences of that term were replaced by the MeSH
> heading, Diarrhea
> Viruses, Bovine Viral. Citations with two specific
> bovine diarrhea viruses - 1
> and 2 were located and the new MeSH headings Diarrhea
> Virus 1,
> Bovine Viral and/or Diarrhea Virus 2, Bovine Viral
> were added to
> those citations.
>
> The MeSH heading Papovaviridae was deleted and two new
> headings
> have been introduced to cover this concept.
> Maintenance tasks were
> performed to add both new headings (Papillomaviridae
> and
> Polyomaviridae) to all citations with occurrences of
> the old heading,
> Papovaviridae.
>
> New Author Name Indexing Policy
> Beginning with 2002 publication dates, NLM will enter full
> author names for
> MEDLINE citations. This new policy will apply to the
> following fields:
>
> Author (AU)
> Personal Name as Subject (PS)
> Investigator Name (IR) - Note: This field only appears
> on MEDLINE
> citations created or maintained by one of our
> collaborating data
> producers, the National Aeronautics and Space
> Administration (NASA).
>
> Full author names are entered when they appear in the
> author position of an
> article, usually on the title page of an article. If only
> the last name and initials
> appear in the author position, then only the last name and
> initials will be entered
> even if a fuller form of the name appears elsewhere in the
> article or in the Table
> of Contents for the journal.
>
> Full author names are currently present on all citations
> created by another
> collaborating data producer, the Kennedy Institute of
> Ethics (KIE), regardless
> of publication date.
>
> Author Searching in PubMed
> For now, full Author Names will not be searchable in
> PubMed.
> Searching author names in PubMed remains the same
> using last name
> plus two initials and suffix if appropriate. PubMed's
> MEDLINE and
> XML display formats will show the full names when
> present.
> Additionally, full author names will not be printed in
> Index Medicus.
>
> Author Initials
> Even with the new 2002 policy of capturing full author
> name, NLM will
> continue its policy of using only two initials for
> searching in PubMed as
> explained above. Initials data are generated from the
> Data Creation and
> Maintenance System (DCMS) ForeName data element using
> an
> algorithm which was reviewed and adjusted as part of
> our year end
> activities.
>
> Other Indexing Policy Changes
> Articles discussing therapies using plants or preparations
> from plants are
> indexed with the MeSH heading, Phytotherapy, a new heading
> for 2002.
> Studies involving plants for therapy will be indexed as
> follows:
>
> Phytotherapy
> disease/drug therapy
> specific plant
> Plant Preparations (or one of its more specific
> terms)/therapeutic use
> plant chemical/therapeutic use (if discussed)
>
> Phytotherapy is reserved for articles in which the plant
> itself, an extract of the
> plant, or the plant chemical whose structure has not yet
> been determined is used
> therapeutically. The MeSH heading, Phytotherapy will not
> be used in those cases;
> eg an article discussing the treatment of ovarian cancer
> with paclitaxel. Paclitaxel was
> originally isolated from the Pacific Yew tree and its
> structure and pharmacologic
> properties are well known and it can now be chemically
> synthesized. This article
> would be indexed with the following headings - notice that
> Phytotherapy is not
> used:
>
> Ovarian Neoplasms/drug therapy
> Paclitaxel/therapeutic use
> Antineoplastic Agents, Phytogenic/therapeutic use
>
> Additionally, maintenance tasks were performed to add the
> new MeSH heading
> Phytotherapy to any citations with:
>
> 1.a heading from the Plants [B6] tree with either
> therapeutic use or
> administration attached as a subheading, or
> 2.the heading Antineoplastic Agents, Phytogenic with
> either therapeutic use
> or administration attached as a subheading, or
> 3.a heading from the Angiosperms [B6.388.100] tree AND a
> heading from
> the Complementary Therapies [E2.190] tree
>
> Other Changes to MEDLINE Data
>
> New Publication Type - Patient Education Handout
> Some clinical journals have begun adding "patient
> pages" that relate to
> substantive articles. The "patient pages" are designed
> for physicians to
> share with their patients or use as talking points
> with patients. Many
> searchers expressed interest in being able to restrict
> to this type of article.
> The new publication type Patient Education Handout
> will allow users to
> limit this way.
>
> Supplementary Chemical Concepts: EC/CAS Registry
> Numbers
> [EC/RN]
> Changes in 2002 MeSH also require changes to some
> EC/RN data,
> including Substance Name [NM], in MEDLINE citations
> during
> year-end processing. These affect not only the MeSH
> chemical concepts
> in category D, but the Supplementary Chemical Concepts
> as well.
>
> Identification of Clinical Trials in MEDLINE
> For the seventh year, NLM continued its work with the
> Cochrane
> Collaboration to enhance the identification of
> clinical trials in MEDLINE.
> For 2001 maintenance, the Cochrane identified over
> 7,200 MEDLINE
> citations to articles published from 1966-2001 to
> which the Randomized
> Controlled Trial or Controlled Clinical Trial
> Publication Type has been
> added. (Over 5,000 MEDLINE citations were similarly
> enhanced during
> 2000 maintenance.)
>
> Citation Subset Values Added to MEDLINE Records
> Citation subset values X, E, Q, and S were added to
> the MEDLINE
> records that had also been included in the former
> AIDSLINE,
> BIOETHICSLINE, HISTLINE and SPACELINE databases,
> respectively. These values ensure that the PubMed
> Journal Citation
> Subsets (i.e., jsubsetx, jsubsete, jsubsetq, jsubsets)
> include all citations
> that were in the former databases, whether the
> citations were unique to
> the database, or derived from other databases (e.g.,
> MEDLINE,
> HealthSTAR). Prospectively, collaborating indexers may
> add these
> citation subset values to new MEDLINE citations.
> Searchers should note
> that citation subset values are multiply occurring
> which means that
> individual citations may be included in several
> subsets, including the
> Index Medicus one (jsubsetim).
>
> Miscellaneous Changes and Corrections
> Abstract copyright statements may be supplied
> electronically by
> publishers to be included in MEDLINE records. The data
> are to reside in
> the DCMS CopyrightInformation data element. However,
> on some
> records the copyright information was appended at the
> end of the
> Abstract data element instead. Maintenance tasks were
> performed to
> move this information to the correct data element when
> necessary.
>
> Maintenance activities also included verifying and/or
> correcting
> publication type assignments on MEDLINE citations and
> updating grant
> acronym information to reflect those currently used by
> NIH institutes.
