December 2008/January 2009 NDF-RT (version name 2009.01.13)

This release reflects content in a new NDF-RT namespace, which is intended to
be the "next generation" of NDF-RT, comprising a multi-namespace approach 
that will restore focus on orderable clinical drugs, ingredients, and 
descriptive classifications. It will also support clinical decision support, 
quality of care research, and FDA SPL drug labeling initiatives.

The central content of NDF-RT now consists of core medication reference 
terminology via NDF and NLM Daily Med updates; salient reference concept 
hierarchies; and description logic-based drug & ingredient classification. 
External content derived from other terminology sources will be integrated 
and maintained via linkages, as opposed to direct incorporation into NDF-RT.

The new iteration of NDF-RT was created by removing and reinserting selected 
concepts and attributes from the November 2008 version of NDF-RT 
[Public Edition]. Some of the information removed will no longer be 
maintained, and some will be maintained elsewhere.  For example, VA Drug 
Interaction concepts, previously maintained in NDF-RT and withheld from the 
NDF-RT Public Edition, were reinserted for and are being included in this new
public edition. Orderable supply concepts (those beginning with XA*) and 
their descendants, NDC-level concepts, and several obsolete VA class concepts
were removed. The following list is a summary of the additions and deletions:

       TOTAL CONCEPTS IN PREVIOUS VERSION (2008.11.11.8AA): 136054

the EXT hierarchy, 7 added to the PE hierarchy, and 4 added to the MoA 
hierarchy. 

The changed concepts count this month is due to two concept name changes. The
old concept name Alcohol Dehyrogenase Inhibitors [MoA] was changed to include
"Dehydrogenase", the correct spelling. The concept Angiotensin-Converting 
Enzyme Inhibitors [MoA] was changed to make "-Converting" lowercase for 
consistency with other hyphenated NDF-RT concept names.

March 2008 NDF-RT (version name 2008.03.11)

This release of NDF-RT Public Edition contains 10 new concepts: 8 added to 
the EXT hierarchy, and 2 added to the MoA hierarchy. 

The changed concepts count this month is due to concept name changes. 
Instances of the acronym "GNRH" in 4 existing concept names in the PE 
hierarchy were changed to "GnRH". In addition, the following changes to EXT
concept names were made, with the former concept names retained as synonyms: 
Angiotensin 2 Receptor Blocker [EXT], Phosphodiesterase 3 Inhibitor [EXT], 
and Phosphodiesterase 5 Inhibitor [EXT] were renamed to include Roman 
numerals, to replicate the original pharmacologic class requested phrases; 
Greek letters in the concept names Interferon Alpha [EXT] and Interferon 
Gamma [EXT] were lowercased; and GnRH Secretion Inhibitor [EXT] was changed 
to reflect the fully-specified name Gonadotropin Releasing Hormone Secretion
Inhibitor [EXT].

February 2008 NDF-RT (version name 2008.02.12)

This release of NDF-RT Public Edition contains 41 new concepts: 13 added to 
the EXT hierarchy, 11 added to the MoA hierarchy, and 17 added to the PE 
hierarchy. 

The changed concepts count is due to subtree reorganization under the new 
concept Autonomic Nervous System Activity Alteration [PE]. In addition to 
this hierarchy reorganization, a second parent was given to any legacy 
neurotransmitter-specific sympathetic/parasympathetic activity concepts in 
the new subtree. Finally, a number of concept names containing 
"Norepinepherine" were changed to reflect the correct spelling.

January 2008 NDF-RT (version name 2008.01.08)

This release of NDF-RT Public Edition contains changes reflecting decisions 
made at the November 2007 SPL IEP face-to-face meeting. The former Additional
FDA Pharmacologic Classes for SPL hierarchy has been renamed to "External 
Pharmacologic Classes", and now contains new concepts whose names replicate
each pharmacologic class string received. These concepts are mapped via role
relationships to appropriate MoA, PE, or Chemical/Ingredient concepts. All 
concepts in this hierarchy have the tag [EXT] appended to their names, 
replacing the former [FDA SPL] tag. In addition to new concepts created 
manually in this hierarchy to reflect recent SPL IEP decisions, 61 concepts 
were added programmatically from former FDA_SPL_Name property values that 
existed for those NDF-RT concepts considered to be one-to-one maps to SPL 
pharmacologic class phrases. These EXT concept names exactly replicate the 
former FDA_SPL_Name property values. All existing FDA_SPL_Name property 
values were then removed, and as this property will no longer be used, the 
property type has been removed entirely from NDF-RT. 

In addition to these 61 concepts added programmatically, there were 72 new 
concepts added to the EXT hierarchy based on submissions from the 
Antimicrobial/Transplant/Hematology FDA list. Other new concepts included 6 
added to the Chemical/Ingredient hierarchy, 5 added to the PE hierarchy, and
11 added to the MoA hierarchy. 

The changed concepts count is due to 14 MoA concepts, which were renamed for 
consistency to include "Activity" instead of "Agents", "Preparations", or 
"Scavengers", and one concept whose former name contained an incorrect 
spelling. Additionally, 29 existing concepts in the EXT (formerly Additional 
FDA Pharmacologic Classes for SPL) hierarchy were renamed, removing the 
[FDA SPL] tag and adding the new [EXT] tag. 

The concept Influenza Neuraminidase Inhibitors [MoA] was retired. The 
newly-created concept Influenza Neuraminidase Inhibitor [EXT] retains this 
former concept's NUI.

November 2007 NDF-RT (version name 2007.11.13)

This release of NDF-RT Public Edition contains 11 new concepts: 4 added in 
the Additional FDA Pharmacologic Classes for SPL list, 6 added to the MoA 
hierarchy, and 1 added to the Chemical/Ingredient hierarchy. 

The changed concepts count is due to two renamed MoA concepts, Tumor Necrosis
Factor Alpha Receptor Blocking Activity [MoA], and Tumor Necrosis Factor 
Beta Receptor Blocking Activity [MoA].

October 2007 NDF-RT (version name 2007.10.09)

This release of NDF-RT Public Edition contains 17 new concepts: 8 added in 
the Additional FDA Pharmacologic Classes for SPL list, 1 added to 
Supplementary Chemicals [Chemical/Ingredient], 1 added to the PE hierarchy,
5 added to the MoA hierarchy, and 2 added to the Chemical/Ingredient 
hierarchy. 

An official NDF-RT SPL IEP decision was made to add a second FDA_SPL_Name, 
beta-Adrenergic Receptor Inhibitor, to the concept Adrenergic 
beta-Antagonists [MoA], which was mapped to both the New Products pharm.
class phrase with the same string and the Cardiac/Renal submission 
beta-adrenergic blocker. Going forward, this approach will ONLY be used when 
the FDA_SPL_Name values are true synonyms.

-----------------------------------------------------------------
August/September 2007 NDF-RT (version name 2007.08.31)

This full release of NDF-RT Public Edition contains the new "Additional FDA
Pharmacologic Classes for SPL" list under "Pharmaceutical Preparations". Its
16 assigned children were created in response to requests for concepts to 
support the FDA Structured Product Labeling (SPL) initiative. Concepts in 
this group represent specific requests for SPL Pharmacologic Class phrases 
that can not be represented by a single new or existing MOA, PE or CS NDF-RT 
concept. This includes phrases that represent therapeutic intent as defined 
by the FDA SPL initiative, as well as those represented by the concatenation
of multiple NDF-RT concepts, and in rare cases ideas that did not fit 
elsewhere within NDF-RT. None of the concepts in this new group are listed in
the MOA, PE or CS SPL files published separately but many have defining role 
relationships to one or more MOA, PE and CS concepts.

The changed concepts count includes concepts changed for remodeling of the 
Nucleic Acid Synthesis Inhibitors [MoA], Protease Inhibitors [MoA], and 
Kinase Inhibitors [MoA] subtrees, as well as concepts affected by new 
FDA_SPL_Name algorithm, and two concepts renamed due to misspellings. 
Fms-like tyrosine kinase (FLT) Inhibitors [MoA] was removed after 
determining that it was not used as a role value for NDF-RT drug modeling.

	135,656 total concepts
	     17 new concepts

	      1 concept removed

-----------------------------------------------------------------
July 2007 NDF-RT (version name 2007.07.10)

This Full release of NDF-RT Public Edition contains no added concepts based 
on FDA submissions for SPL. Changes in this version of NDF-RT occurred solely
due to a few changes and 85 additional mappings of NDF-RT Disease concepts 
that already had at least one existing SNOMED CT mapping. None of these were 
on the current SPL Problem List (Jan. 2007). These changes resulted in the 
creation of at least one additional map from that Disease concept to a 
SNOMED CT concept on the SPL Problem List. A map (recorded as a property on 
the concept) to a SNOMED CT concept on the SPL Problem List will now be 
called the SPL_Problem_List_Mapping_ID. In addition, the existing SNOMED_ID 
property was renamed to SNOMED_Mapping_ID. This final change resulted in the 
large "changed concept" count.

	135,640 total concepts
	      0 new concepts
	   2478 changed concepts 
	      
-----------------------------------------------------------------
June 2007 NDF-RT (version name 2007.06.12)

This Full release of NDF-RT Public Edition contains changes derived from SPL 
Pharmacologic Class requirements plus changes derived from a 
re-synchronization of the Chemical/Ingredient hierarchy with the current 
version of MeSH (2007).

    135,640 total current concepts
	324 new concepts
	 33 changed concepts
	 21 deprecated concepts (reflects semantic duplicates noted either 
	 due to formal SPL decisions or MeSH refresh QA process. Prior 
	 meanings and NUIs of these concepts are attributed to existing 
	 NDF-RT concepts.)

A substantial reduction in the number of synonyms is reflected in this 
release due to the improved accuracy of synonym assignment based on UMLS 
Metathesaurus. Removed synonyms were all from the Chemical/Ingredient 
hierarchy. Chemicals and Ingredients concepts were derived from 2007 ASCII
MeSH files.

-----------------------------------------------------------------
May 2007 NDF-RT (version name 2007.05.08)

Starting with the May 2007 release a new property has been created: 
FDA_SPL_Name. This property will only be added to concepts when there is 
requirement for a concept representation (IE: a term name) preferred for SPL 
use that is not the existing "preferred name" for the concept. The value 
of the FDA_SPL_Name property may be an existing synonym, or it may be a new 
term representation. If it is new, it will only be additionally added as a 
synonym for concepts NOT derived from MeSH. This was done to keep synonyms 
algorithmically consistent with the UMLS MeSH synonym list for that concept 
(as noted above.) Only concepts requiring these additions will carry this 
property. This means that any SPL user must determine if that property exists
for a concept and use the value as the concept preferred name.

This Full release of NDF-RT Public Edition contains only a few changes 
modeled and approved by the ICCB committee.

  135,337 total current concepts
        6 new concepts
        1 changed concept
        1 retired concept

Chemicals and ingredient concepts were derived from MeSH 2006 (2006_05_01)

March 2007 NDF-RT (version name 2007.03.13)

As of the March, 2007, the provision of NDF-RT content outside the VA system 
will not include elements deemed only of value to internal VA operations. 
This "extract" will be known as the NDF-RT Public Edition and will contain 
all of the core NDF-RT concepts that existed in previous releases and all 
concept NUIs will remain unchanged. In essence the Public Edition only 
removes selected VA-specific properties, qualifiers, associations and a few 
Kinds that represented information required for unique internal VA 
activities. All Roles remain unchanged. 

These changes are expected to have no impact on non-VA use of the NDF-RT.

Listed below are the changes implemented beginning with this release.
