New MeSH 2021 S-T questions

[LindseyOB]

Social Cognition (D000083282) --- Link to Social perception (sh 85123982) ? "Social Perception" is a separate MeSh heading higher up the tree

Thrombotic Stroke (D000083244) --- Is a broader mapping to Stroke too broad?

Treatment Switching (D000085582) --- Link to Crossover trials ((DLC)sh 89001948) ? It seems like these are different, but I could definitely be wrong.

Further question about updates:

Social Interaction (D000083505), the previous indexing was Interpersonal Relations (1978-2020). Do we leave the "old" 750 in the authority record?

In the case of updates about disorders/diseases that create a more discreet heading, any tips on when to map? For example, see Semicircular Canal Dehiscence (D000084322). The previous indexing was Labyrinth Diseases (1999-2020). Should I automatically map this new heading to Labyrinth (Ear) |x Diseases?

My thoughts, but I welcome input from others:

• Social Cognition - I'd do a broader mapping to Social perception
• Thrombotic Stroke - relationship to BM Stroke is too far removed - no match
• Treatment Switching - I'd say no match. Crossover trials already maps to Cross-Over Studies (D018592) which seems slightly different
• Social Interaction - In this case I'd remove the map to Interpersonal Relations (and make sure it's changed in both LCSH and MeSH) - so now Social Interaction (D000083505) =Social interaction (sh 85123965) and Interpersonal Relations (D007398) =Interpersonal relations (sh 85067484)
• I'd do a BM to Labyrinth (Ear) $x Diseases, unless there is a more specific LCSH heading available
