2002 CANCERLIT Update News

CANCERLIT has been reloaded for 2002. Changes include: eight new fields; one changed field; 847 descriptors added, representing concepts with no directly corresponding descriptors in 2001 MeSH (for example, new concepts and records); 185 descriptors replaced with more up-to-date terminology; 47 descriptors deleted; and 2041 see references (print entry terms) added.

New Tree Including New Heading and Other Changes

The new MeSH heading Nanotechnology has been added for 2002; it is not reflected in the published Annotated Alphabetic MeSH. This new heading has two tree numbers, H01.603 and J01.897.524.

Heading Changes
The following changes were made to 2002 MeSH since the time the MeSH database and printed publication was first made available: change in tree number for Albania to Z01.542.248.020, and the deleted heading Herbs has been replaced by the heading Angiosperms, not replaced by Phytotherapy as published in the Annotated Alphabetic MeSH.

Viruses
All viruses were reviewed and updated to conform with the 7th Report of the International Committee on Taxonomy of Viruses (ICTV). The most significant change is its official approval of the concept of viral species and the codification of the official form of virus species names using the format of first letter of first word capitalized, first letter of other words all lower case.

In line with the Report, many new virus names have been added to MeSH and older terminology has been changed. Among the significant changes, the names of all the genera in the family Retroviridae have been revised. Most species and strains of HTLV viruses (now under Deltaretrovirus) have been reorganized and specific coxsackie viruses are now referred to as specific enteroviruses.

Complementary and Alternative Medicine
The terminology related to complementary and alternative medicine has been re-structured into sub-groups in order to facilitate searching those divisions. The field can most broadly be divided into physical, sensory, mind-body and spiritual, plus some which occur in more than one category. Physical includes acupuncture, musculoskeletal manipulations done by professionals; sensory includes play-, dance-, sound-, color- and other such therapies; mind-body includes biofeedback, breathing, hypnosis, laughter, relaxation; spiritual includes faith, magic, occultism, and witchcraft. Unclassified includes homeopathy, phytotherapy, and natural childbirth.

Plants and Phytotherapy
Terminology related to plant family and genera headings have been greatly expanded with more use of the scientific Latin binomial nomenclature and less use of common names as preferred terminology. In addition, indexing of studies involving plants for therapy are now being coordinated with Phytotherapy and the most specific plant (family, genus or species) in B6 that is available. Because of the importance of what part of the plant is being used, coordinate indexing uses specific Plant Components (B06.413).

Bioethics
Through joint effort with the Kennedy Institute of Ethics, enlargement and enhancement of terminology in the area of bioethics has been added. This cooperative project is in preparation for the addition into PubMed of the journal citations, which formerly constituted the BIOETHICSLINE database. Some 50 new descriptors have been created and numerous other changes have been made in MeSH.

Transport and Carrier Proteins
There are 50 new categories of transport proteins under Membrane Transport Proteins. Also, 34 headings that were formerly under Carrier Proteins, Membrane Proteins or Permeases are now arrayed under Membrane Transport Proteins. Many of the 2,018 Supplementary Concept Records (SCRs) that formerly were mapped to Carrier Proteins are now mapped to specific categories listed under membrane transport proteins. Several non-mammalian organism-specific protein classes have been added to accommodate the increasing need for indexing of proteins from model organisms. Many of the organism-specific SCR proteins are now more clearly distinguished with organism names and heading maps to these protein classes. The High Mobility Group (HMG) proteins have been organized according to new nomenclature guidelines, which were published in: Trends Biochem Sci. 2001 Mar;26(3):152-3. The new rules were established with the coordinated efforts of staff from MeSH, NCBI and scientists working in the field of HMG protein research.

Urtica Diocia
Urtica Diocia is misspelled in the CANCERLIT tree as well as the input data. If you need to search for this term, use "Urtica Dioica" in the search.

Periodic Updates to Tree
Although NLM updates their tree on a weekly basis, Ovid will not be doing this. As a result of this change, some terms are not included in Ovid's version of the tree. The new terms that are added weekly are searchable in Ovid's CANCERLIT, but do not display in the record. Nanotechnology is one of the terms that is not included in the tree with the reload. You can search for the term, but it does not display.

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 to 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 allows users to limit this way.

Citation Subset Values Added to CANCERLIT Records
Citation subset values E, Q, S, and X have been added to the CANCERLIT records which had been included in the former AIDSLINE, BIOETHICSLINE, HISTLINE and SPACELINE databases. Searchers should note that citation subset values are multiply occurring, which means that individual citations may be included in several subsets.

Eight New Fields in CANCERLIT

ED	Entry Date [Phrase Indexed]
 	20011215.ed.
 	20000929.ed.
The Entry Date (ED) field contains the issue (year, month and day) in which a document 
appeared in Index Medicus. This index contains the Revision Date (RD) of the document, 
if present, and appears in the format YYYYMMDD. This field also displays in the Update 
Date (UP) field, which is the date the record was added to Ovid's Medline.

IA	Investigator Affiliation [Word Indexed]
	seattle.ia.
The Investigator Affiliation (IA) field contains the affiliation of the investigator of 
the article, and displays as part of the Institution (IN) field.

IR	Investigator [Phrase Indexed]
	curtin sb.ir.
The Investigator (IR) field appears in citations created or maintained by the National 
Aeronautics and Space Adminiatration (NASA). The format for investigator is last name 
followed by one or more initials: Smith JC or Smith J. It displays as part of the author 
(AU) field. 

MI	MEDLINE Identifier [Phrase Indexed]
	20000004.mi.
	67179603.mi.
The MEDLINE Identifier (MI) field contains the NLM Class Maintenance number. This number 
was formerly the Unique Identifier (UI).

NT	General Note [Display Only]
The General Note (NT) field contains either a series name and number or general 
supplementary information about an item. The notes may include information on the
