    new in 2005 DeCS This document highlights the additions and
    changes in 2005 Health Science Descriptors (DeCS). In addition to the
    annual changes related to the 2005 Medical Science Headings (MeSH), the
    main novelties in 2005 DeCS are the creation of the Science and Health category by PAHO IKM/RC Unit (Information Knowledge Management/Research Promotion
    and Development), date of update February 2005, and the creation of the Health Surveillance category, in partnership with the National Health
    Surveillance System of the Scientific and Technical Knowledge Management
    Office - GETEC, General Management for Knowledge and Documentation ANVISA (the Health Surveillance Agency of the Brazilian Department of
    Health), date of update April 2005.   Overview
    of Vocabulary Development and Changes   ·        
    487 MeSH descriptors were
    added. The ten subcategories which received the greatest additions were
    animals (100), bacteria (50), enzymes
    and coenzymes (47), amino acids,
    peptides and proteins (46), humanities (23), investigative
     techniques (15), digestive system diseases (13), organic compounds (11), heterocyclic compounds (10), diagnosis (10), biological
    phenomena, cell phenomena and immunity (10).  ·        
    129 MeSH descriptors replaced
    with more up-to-date terminology;  ·        
    60 MeSH descriptors deleted;  ·        
    1482 see references (entry
    terms) were added, of which 340
     in MeSH descriptors. ·        
    the new hierarchical category
    Science and Health (SH) totaling 218 descriptors and 277 entry terms (cross
    references); of these totals, 137 descriptors and 56 entry terms are new; ·        
    the new hierarchical category
    Health Surveillance (VS) totaling 833 descriptors and 773 entry terms
    (cross references); of these totals, 271 descriptors and 227 entry terms
    are new; ·

 Organisms -- B Category:The taxonomy of Hominidae, the family comprising bipedal primate
    mammals, which includes humans, has been updated for 2005. Also, similarly to what occurred in 2004 to the check tag Animal (see DeCS 2004 edition overview and
    the link below), the check tag Human will be
    changed to a new descriptor Humans. It
     will function as both a descriptor and a check tag when human is only a secondary theme in the article and will be indented
     under HOMINIDAE in the MeSH hierarchy, which, in turn, is indented under
     Animals. Both the
     plural and the singular forms may be used for searching literature. The word Human, in the singular, will refer to the new descriptor in the
    plural.

    and the Check Tag Human; Resulting PubMed and NLM Catalog Change to Search
    for Animals. NLM Tech Bull. 2004 Nov-Dec;(341):e6.   The trees of the following
     organisms were revised and greatly expanded: Carnivora, Birds,
     Cyanobacteria, Clostridium, and Porifera. In the cases of Carnivora and
     Birds, there are now specific headings for many of the genera and species,
     with their scientific names. There are now headings for 20 species of
     Clostridium (previously 4) and for 7 specific subtypes of Clostridium
     botulinum. The sponges (Porifera) now have headings for several of the
     genera. For more details see What’s New for 2005   Chemicals and Drogas -- D category: The subcategory Macromolecular Substances (D05) was added with 132
    descriptors. For other changes in the D category, see What’s New for 2005 MeSH.
   Historical Events - Category KIn Category K, descriptors were added or replaced for consistency for
    information about major historic events and eras:
 
     
      | Eras | Events |  
      | History, 15th Century | American Civil War |  
      | History, 16th Century | American Revolution |  
      | History, 17th Century | Chernobyl Nuclear Accident |  
      | History, 18th Century | Crimean War |

      | History, Modern 1601- | Vietnam Conflict |  
      |   | World War I |  
      |   | World War II |  Support TagsThe MeSH Heading check tags reflecting grant support have been changed for
    2005. Changes were made because the former name of the descriptor was a
    less accurate label for the concept. The concept is support of research,
    not support in a general sense. The changes are as follows:
 2004: Support, Non-U.S. Gov't 2005: Research Support, Non-U.S. Gov't
 2004: Support, U.S. Gov't, P.H.S.2005: Research Support, U.S. Gov't, P.H.S.
 2004: Support, U.S. Gov't, Non-P.H.S.2005: Research Support, U.S. Gov't. Non-P.H.S.
