RIP NHANES?

As the piece below points out: NHANES may actually be aligned with some healthy eating and chronic disease prevention goals of MAHA.

Just a reckless wrecking ball

Protecting the nation’s public health demands data, whether it be new measles cases, a surge in ER visits, or shifting patterns in obesity. The most recent job cuts at the CDC threaten the mostly unseen foundation of that research enterprise.

CDC team running top survey on health and nutrition is laid off

NHANES has collected data on eating patterns, diabetes and other common diseases for decades. The CDC team that runs it has been fired.

Interesting post on the use of GWP* in climate policy. While focusing on methane, the discussion reminds one of desflurane and GWP100.

Individualized perioperative MAP targets did not lower rates of organ injury or death after major abdominal surgery compared with routine blood pressure management at MAP ≥65 mm Hg.

It’s Bookshop Day so here’s a poem in celebration of all those amazing bookshops out there.

Never Judge a Bookshop by its Cover

It may call itself a bookshop, but don’t be fooled by that.
There may be books in the window, on the tables and shelves,
but really, it’s a travel agent selling all-immersive holidays,
weekend breaks, first-class tickets to other worlds,

with a low carbon footprint. It’s a pharmacy as well,
dispensing medicines, pick-me-ups, balms: if symptoms persist,
please consult your local bookseller; it’s a tailor’s, offering
a made-to-measure service to achieve the perfect fit;

and a hardware store, with a range of empowering tools
to fix you up, recharge your batteries, switch on lightbulbs.
Its walls are lined with treasure as precious as any jeweller’s,
and twice as bright. Spines shine gold, silver, sapphire, emerald;

there are diamonds amongst them. It’s a garden centre,
a place where ideas get planted and a thousand stories bloom,
and a greengrocer, selling fresh, locally-sourced produce,
as vital as your five-a-day and more readily consumed.

It’s a multiscreen cinema. Peek behind the curtain
of each jacket and you’ll find a movie waiting silently to begin.
A stationer’s supplying notepads, reams of paper,
with the words conveniently filled in

to save you both the time and bother. A wholefood store
and a fast-food joint. A cosy haven from the cold.
A friendly, family restaurant: Today’s special will revive
a flagging spirit and restore a lagging soul.

It’s a tourist information centre equipped with maps
and helpful guides to steer us on our way.
A busy square in which a whole town gathers
or just a place to hold the world at bay

for a few untroubled stolen minutes. It’s itself,
and yet it’s something larger, a universe so vast
you could spend ten thousand lifetimes there –
it may call itself a bookshop, but don’t be fooled by that.

Over 40% of corn grown in Indiana is used to make ethanol that cars burn. One acre of corn yields about 16,500 vehicle-miles per year of ethanol, which sounds high until you realize that one acre of solar yields about 2,700,000 vehicle-miles per year: 16,000% more driving for a given plot of land.

Inhaler-related #greenhouse gas emissions in the VA health system dropped 68% from 2008 to 2023, primarily due to policy and formulary changes favoring lower-emission inhaler options.

ja.ma/4nYMM54

Greenhouse gas emissions from inhaled medications, 2008-2023. Emissions from SAMA & SABA-SAMA decreased, ICS-LABA increased, SABA stable. Key events: CFC inhaler phase-out, VA formulary changes favoring DPI over MDI.
