My favorite smartphone medical app is still ultrasound.
Handheld ultrasound was introduced > 9 yrs ago, but still there's very limited uptake. A reminder that It took 20 years before doctors accepted Laennec's stethoscope invention from 1816.
Getting instant, detailed, dynamic views inside the body, inside the heart via a smartphone
This year, we put together an atlas of all the views inside the body that can be obtained

3 years ago I did a total body medical selfie (except the brain)
Besides eliminating most formal studies by incorporating ultrasound in the physical exam, you never know when it comes in handy....
like diagnosing my own kidney stones :-(
These are the 1st 5 devices w/ @US_FDA clearance. More since, and more to come. The price has to drop. But that isn't what is holding adoption back. It's (1) billing, since health systems make plenty w/ > 100 M ultrasounds in the US/yr &(2) training for it to be rapid and useful

This week @BBCTwo aired a 1 hr program on #AI for #healthcare,
bbc.co.uk/programmes/b0b…
produced @teamWingspan @ArchieBaron, moderated by @FryRsquared, & brought to my attention by @pearsekeane. It didn't show in the US, so I am going to review a few key points here
First, the #AI hype from @babylonhealth, a symptom checker, which is a major focus of the documentary. A quote from their CEO:
[No you're not.]
Remember the paper the company posted on their website claiming their #AI it outperformed 7 doctors (and other claims). Well apparently that was submitted to peer-review @TheLancet and here is the preview:

3 @NEJM papers of a randomized trial of >19,000 people by @JohnMcNeil6 @ASPREE_aus and colleagues
The results on lack of any cardiovascular benefit but increase in bleeding nejm.org/doi/full/10.10… @NEJM
Congratulations to the @ASPREE_aus investigators for taking on this important endeavor, not accepting dogma, and publication of the unexpected results with lucidity.

Trying the micro-needle blood draw (my 1st experience w/ this)
It was a truly painless, efficient way to collect 100 ul of blood
Just push the green button; it took 2 minutes to get the red light to go on (= full sample)
According to the company @7sbio, the sample is sufficient for whole genome sequencing and 6-7 lab tests (not CBC or electrolytes). I have not seen any published data. This is one of at least 4 companies w/ micro- needle (so small you can't see them) blood draws.
Their 2018 paper @natBME provides the methodology, the data for HbA1c (@US_FDA approved) vs venous standard and projected price of $5.

While the world careens towards WW3, Trump/@GOP/media wrangle obsessively over an ineffectual wall, ostensibly keep out impoverished, unarmed migrant families (boogeymen).

If 💰is to be spent protecting USA, let’s spend it instead on subs, drones, planes, choppers.

Thread: As the high mountain ice melts back, archaeological finds from the ice become older and older. The earliest archaeological finds from the ice in Norway are now five fragmented arrowshafts dating back to 4000 BC (one in picture). How old can the finds get? /1
Is it possible that future melting could reveal archaeological finds that date back to the last Ice Age, as envisaged in this prophetic cartoon by Gary Larsson? Could we find remains of Ice age hunters at the bottom of the ice? /2
Surprisingly perhaps, and contrary to popular belief, the ice in the high mountains does not date all the way back to the last Ice Age. Most mountain ice in the Northern Hemisphere has a maximum age of 7000-9000 years. /3

Whenever one attempts to learn more about the antecedents of Ganesha, here's what we read -

"Ganesha is one of the youngest Indian deities. He originated most likely in the Gupta period".

This seems to be the "mainstream" academic view. But should we accept this?

(Contd..)
I am aware of two references to Ganesha in Vedic literature.

In Maitrayani Samhita associated with Krishna Yajurveda.

In Taittareya Aranyaka also associated with Krishna Yajurveda
In Maitrayani Samhita, here's the allusion to a deity strikingly reminiscent of Ganesha -

tat karāṭāya vidmahe hastimukhāya dhīmahi
tan no dantī pracodayāt

The word Hastimukha (elephant faced) is clearly suggestive of Ganesha

1/ Six yrs after US consulate attack in Benghazi, I got NEW FOOTAGE.

In Benghazi I identified 17 extremists seen near/in consulate during attack.

6 out of 17 are in vid.

Witnesses say: Most of 17 killed/fled city. 1 lives in Berlin. 1 might be in Sweden
2/ As you know by now, my tv report for @akhbar is in Arabic.

But please do follow this thread where I will tweet out the relevant details in English.

#Benghazi
3/ Ten days ago I left Benghazi where I spent 3 weeks.

Ansar al-Sharia, the terrorist group that attacked US consulate on 11 Sept 2012 is now dismantled, defeated by Libyan army.

Although it happened 6 yrs ago, I used my time in #Benghazi to re-investigate the attack.
