Additional Changes

Several classification issues were investigated and resolved.

Issue

Resolution

Where to class non-human models as well as anatomic models of plants

Added SubIndexes (SIs) for animal and comparative anatomy of humans and animals to index record for Models, Anatomic.  Also added SI for  anatomic models of plants

Where to class the new 2022 MeSH Epidemiological Models is not in the index. It trees under Models, Biological which is classed in QH but probably better classed in NLM classification

Epidemiological Models was added to index classed at WA 950.  Adjusted header above WA 950 to add Epidemiologic Methods

Where to class Models, Immunological. The parent term, Models, Biological points to QH 324.8.

Added Models, Immunological to the index classed at QW 26.5.

Where to class Epigenomics: QU 460 with the broader term of Genomics or QU 475 based on the scope note

Created new number QU 476 Genetic Epigenesis. Epigenomics indented under QU 475. Reclassified pertinent child terms. Added note to QU 460: Classify epigenomics at QU 476.

Where to class Birth Setting. Its parent term, Parturition, is classed at  WA 300. Its child term, Home Childbirth, is classed at WQ 155.

Added Birth Setting to the index classed at WQ 155.Changed the caption at WQ 155 to broaden it from Home childbirth.

Where to class contact tracing in general. Currently the index only has guidance for contact tracing of sexually transmitted diseases

Added SI General WA 110 under Contact Tracing

Domestic Violence is classed at WA 308 which is captioned Family Health.  These are very different subjects.

Family Violence (the MeSH Entry Term for Domestic Violence) was added to the caption at WA 308

Where to class psychology of athletes.  Should it be classed in WA 305 for mental health issues of special groups or with Sports Medicine in QT 260? 

Created new number for Sports psychology at QT 264. Added to index: Psychology, Sports QT 264

Add SI Psychology QT 264 to index terms:

·        Athletes

·        Athletic Performance

The only class number for Speech Intelligibility is in WM.  Speech Intelligibility is treed under Speech. Need a general number.

Classed Speech Intelligibility only with Speech at WV 501.

 

Where to class collective biographies of traditional healers?

Created new number for Collective Biography of Traditional Healers  WZ 112.5.T7. Added SIs for this new number under all Traditional Medicine terms since there currently are no person terms in MeSH. 

Where to class works on broad urogenital diseases that cover kidney, upper urinary tract, bladder, urethra, prostate, testis, penis, scrotum and adrenal gland. Currently the index for Urogenital Diseases points to WJ 700 which is general works on Male Genitalia.

The range header above WJ 140 and the caption at WJ 140 were broadened from Urologic Diseases to Urogenital Diseases.  Added note at WJ 140 to classify genital diseases at WJ 700.  Adjusted index record for Urogenital Diseases.

Should Vascular Diseases $x surgery be classed at WG 170 for Vascular surgical procedures or WG 505 for Vascular diseases (General or not elsewhere classified)

Added SI Surgery WG 170 to index record for Vascular Diseases.

Infanticide and Abortion, Criminal are both  classed at W 867 but they are unrelated concepts. Infanticide trees only under Homicide. Abortion, Criminal is a sister term to Homicide, but does not tree under it.

Removed Infanticide from W 867 caption.  Reclassified Infanticide with Homicide

Review physical examination WB area to evaluate accuracy of classification and completeness

A mini-systematic review of the WB 205-WB 286 Physical examination area was conducted. Several WB captions were changed to reflect the technique (e.g., Blood pressure was changed to Blood pressure determination). Terms treeing in the MeSH tree Physical Examination [E01.370.600]  were evaluated.  Several index terms were added (e.g., Respiratory Rate).
