Organization for the Study of Sex Differences (OSSD)

B Penaveler Bernabe: Perinatal depression is complex - what about using the gut microbiome? @ossdcomm.bsky.social we cannot study things in isolation.

Sex differences in metabolism exists across a wide variety of outcomes. Body composition energy storage etc. @swhr.bsky.social @ossdcomm.bsky.social #OSSD25

Up next @bonniee-leee.bsky.social on how previous parity influences functional connectivity in an animal model of Alzheimer risk (hApoe4) - bonnie calls this the Parity Paradox www.biorxiv.org/content/10.1...

Had a great time presenting my latest work on effects of pregnancy and AD risk on functional connectivity in middle age at #OSSD2025 🧠⚡️

Thank you @ossdcomm.bsky.social @whrcluster.bsky.social @camhnews.bsky.social #womenmind for hosting this fantastic Pre-Meeting and the opportunity to speak!!

Bonnie looked at zif268 activation across 19 subregions. And found greater efficient networks in the primiparous WT. different eigenvector centrality (influence) based on different brain regions with parity and genotype. @bonniee-leee.bsky.social @ossdcomm.bsky.social

I’m at the premeeting on women’s health @ossdcomm.bsky.social our 3rd annual event. Sponsored in part by @whrcluster.bsky.social & #womenmind @camhnews.bsky.social follow along to see highlights
