The National Library of Medicine has created a Web site aimed at the special needs of the inhabitants of the Arctic. The new site, Arctic Health, has sections devoted to chronic diseases, behavioral issues, traditional medicine, environment/pollution, and environmental justice. It is the first in what may become a series of health information Web sites for special populations and the health professionals who serve them.

New Clinical Advisory Issued

November 09, 2001 [posted]

The National Eye Institute has issued a new Clinical Advisory, Antioxidant Vitamins and Zinc Reduce Risk of Vision Loss from Age-Related Macular Degeneration. Same Nutrients Have No Effect on the Development of Cataract.

A nationwide clinical trial reported that high levels of antioxidants and zinc significantly reduce the risk of advanced age-related macular degeneration (AMD) and its associated vision loss. These same nutrients had no significant effect on the development or progression of cataract. These findings were reported in the October 2001 issue of Archives of Ophthalmology:

MeSH® 2002 Files Available for Downloading

December 06, 2001 [posted]

The 2002 version of the MeSH vocabulary in ASCII and XML (eXtensible Markup Language) format may now be downloaded at no charge from http://www.nlm.nih.gov/mesh/filelist.html after completion of a brief online Memorandum of Understanding. This is the first year that MeSH data are available in XML format. A sample XML file, three MeSH-related DTDs (Document Type Definition), and documentation are also available from this Web site. The three DTDs are: Descriptor DTD for MeSH Heading records, Qualifier DTD for subheading records, and SCR DTD for Supplementary Concept Records (formerly known as Supplementary Chemical Records).

The MeSH files available for download are:

  1. XML and ASCII MeSH - contains complete records for all descriptor, subheading, and supplementary concept records. These files are updated periodically. Current plans call for a weekly update, usually involving only supplementary concept records. However, minor changes to descriptors and qualifier records (e.g., correcting typographical errors) may take place and be present in updated files.
  2. MeSH Trees - contains descriptors with their associated hierarchical tree numbers; sorted by tree number; subheadings and supplementary concept records are not included; updated annually.
  3. MeSH in MARC-compatible format - contains MeSH Headings, subheadings and combination MeSH Heading/subheading records in MARC-compatible format; supplementary concept records are not included; updated annually.
  4. Pharmacological Action Lists for 2002 - contains pharmacologic actions of a given drug and drugs with a given pharmacologic action

The 2002 MeSH tools may also be ordered from National Technical Information Service (NTIS) in printed format. See the Technical Note in the September-October 2001 issue of the NLM Technical Bulletin, titled MeSH® Tools 2002 Available for Purchase.

[Tree Number Change Made on December 10, 2001: NLM made a last minute change to the 2002 tree number for the MeSH Heading Albania. The 2002 tree number has changed from Z01.542.248.000 to Z01.542.248.020. The MeSH files available for download on Monday December 10, 2001 from http://www.nlm.nih.gov/mesh/ include this change.]
