I have no idea which #vaccine @realDonaldTrump was talking about today. But if we are going to have a vaccine before 2021, it will be one of these seven.
I've definitely noticed this phenomenon in American diet culture of late.
But high-protein diets may not be all they are cracked up to be. Why? A new study in Nature Metabolism puts the blame squarely on a single amino acid: leucine.

OK there are three macronutrients. Your caloric intake will be comprised of some combination thereof, and basically all of the diet wars of the last 40 years can be cast in terms of macro content.
When I was growing up (it was a time called the 80s. Thing were... interesting) low-fat was the crazy. Remember "fat makes you fat"?
Does it seem like your hospital patients are getting more... complicated? They are!

Just went through this paper from @JAMAInternalMed which, like all good papers, comports with my prior beliefs ;-). No but seriously, I definitely feel like hospital complexity is rising.
Data comes from British Columbia - good for 2 reasons. 1) Universal EHR so you capture all hospital admissions 2) Universal healthcare - so you don't need to worry as much about access issues, etc.
I believe that RNA therapeutics will completely transform medicine. Imagine a future where, instead of taking medications daily, you take a shot maybe once a year. That future is, basically, here.

Currently, this is more or less how our drugs work. They do something to a protein. Inhibit it, cleave it, block its binding to some receptor, speed its degradation, etc.
And, if you really think about it, disease is mediated by proteins. High cholesterol? Protein problem. Sepsis? Proteins. Viral infection? Viruses hijack our cells to make their... proteins.
AI in Medicine is suffering from what I would like to call "The Cassandra Problem"

I am thinking about this issues this week thanks to this study, appearing in @JAMANetworkOpen, which examines the utility of a model that predicts blood clots in hospitalized kids. (2/17)
The model takes in a bunch of data from the electronic health record, and makes what turns out to be a pretty accurate prediction about the risk of blood clot (AUC~0.90). (3/17)
Absolutely fascinating @JAMA_current paper this week suggesting that Cerebral Amyloid Angiopathy may actually be infectious. (Thread)
The background here is that CAA is the second most common cause of intracerebral hemorrhage (brain bleed) after hypertension. There are some genetic causes, but most are thought to be idiopathic. Just amyloid getting deposited for no clear reason.
But there have been some clues that there might be a transmissible agent involved. This @Nature paper describes cases attributed to contaminated cadaveric pituitary hormone. nature.com/articles/natur…
37 degrees Celsius, 98.6 Fahrenheit. That's normal body temperature, right?
Wrong.
New data suggests true "normal" is 98.0 degrees. (thread)
We get 98.6 degrees from this guy Karl Wunderlich, who measured 1,000,000 temperatures from 25,000 Germans in the mid 1800s. He was really the first to realize that "fever" was not itself a disease, but a symptom of a disease.
He took the average, got 98.6, and that was that. UNTIL NOW.
(Ok honestly, people have known this was wrong for a while, but the new data is cool).
