@ccolvin94.bsky.social presents meticulously thought-thru & generated results on life course earnings trajectories & cognitive decline, by birth cohort. The #MELODEM2025 equivalent of a walk-off HR will launch us into deep thoughts, conversations, and collaborations over the coming weeks and months.

More enlightening lightning (talks) at #MELODEM2025: Justina Avila-Rieger dares to wade thru the thicket that is reproductive status (and aging) in relation to dementia risk. Idea: exploit DNA methylation, which can reflect changes in the endocrine system and hormonal status.

Fluoride. Great for oral health and stunning teeth. Does it exposure to it in childhood related to cogn later in life? @ #MELODEM2025, Rob Warren (U MN) points out the extraordinarily high exposures in studies of kids' IQs: not relevant to what's in our public water supply.

A key ingredient to the appeal and success of #MELODEM2025 (as with other #MELODEM mtgs) comes from the generous blocks of time dedicated to discussion. And a key ingredient of that discussion is excellent moderating.

@palolili23.bsky.social argues (4 #MELODEM2025) that causal estimands have 4 elements + a 5th: intercurrent events. Ie, events that prevent us from observing the exposure or outcome, e.g., death.
