The WHO updated its dementia guidelines today, adding air pollution as a preventable risk factor for the first time. Meanwhile, the FDA approved the first oral PCSK9 inhibitor for high cholesterol, and a new study suggests a genetic switch could unlock mammalian regeneration.
Two major public health stories today: one about preventing dementia, the other about a new cholesterol drug.

The WHO now says 45% of dementia cases could be delayed by tackling 14 modifiable risk factors, with air pollution added for the first time. It's a concrete shift in public health messaging.

The FDA approved Lipfendra (enlicitide), the first oral PCSK9 inhibitor for high cholesterol. No more injections for patients who need this class of drug.
A fascinating study on why some mammals regenerate and others don't points to a single molecular switch.

Researchers found that rabbits regenerate ear tissue but mice don't because of a retinoic acid switch. They reactivated it in mice with supplements, a step toward understanding mammalian regeneration.

A physician argues that doctors rarely ask women about their jobs, missing workplace-linked health issues from menstruation to menopause. It's a simple missing question with big implications.
