et2o··on Cardiac implantable electronic devices' longevity: A novel modelling tool
Cardiology fellow here. The more you have to pace the shorter the battery lasts? Struggling to see what the novelty is here.
et2o··on Mapping the off-target effects of every FDA-approved drug in existence
People have been doing this for literally decades. Check out work by Tattonetti
et2o··on Weight-loss drug found to shrink muscle in mice, human cells
This is most likely a good thing. It isn't killing cardiac myocytes, it's probably assisting with reverse remodeling. Fits with why we know it helps in heart failure.
et2o··on CrowdStrike Update: Windows Bluescreen and Boot Loops
You have no idea how a hospital or modern medicine works. It needs to be online.
et2o··on CrowdStrike Update: Windows Bluescreen and Boot Loops
Because essentially every large hospital in the USA does?
et2o··on EpiPen For Heart Attacks? Idorsia Launches Phase III Study Of Selatogrel (2021)
None of these works nearly as well as angioplasty
et2o··on Boom announces successful flight of XB-1 demonstrator aircraft
Just wrong. Read about the 7J7. The 787 cost something north of 20 billion to develop. The clean sheet 737 would have cost much more in today’s dollars. Boeing makes an average of less than 5% profit margin from the 1970s to now. It was a relatively obvious financial decision from Boeing’s perspective.
et2o··on Boom announces successful flight of XB-1 demonstrator aircraft
Shame on you.

We will not have supersonic transport for average people unless outsiders do it first. There are only two meaningfully large manufacturers now, Airbus and Boeing.

Boeing and Airbus both cannot financially afford a technologically promising but possible failure now. Boeing built the 737 MAXX because they couldn’t afford a clean sheet update of 70-year old technology despite the savings. Airbus lost almost as much as the entire company was worth on the A380, kept afloat by EU subsidies.

All new technology happens for the wealthy first - we would not have smartphones today if Apple was forced to price them at the median price of cell phones in 2004.

et2o··on Sodium ascorbate treatment for sepsis moves to next phase of human trials
This has been beaten to death in high quality randomized controlled trials in sepsis. Don’t believe a university press release lol. HN is a pretty poor source of health information overall.
et2o··on Sodium ascorbate treatment for sepsis moves to next phase of human trials
This is a simplification. For example niacin (vitamin B3) excesses cause cholesterol to become more atherogenic. And supplementation in patients without deficiency is ultimately harmful.
et2o··on A DIY ‘bionic pancreas’ is changing diabetes care
Your pancreas actually does know things like that you've ingested a lot of carbohydrates before they enter the bloodstream, etc. Certainly there is also a response to exercise that occurs before you coiod easily detect it with a CGM. There are very complex brain-gut-pancreas interactions mediated by a variety of molecules/hormones.
et2o··on A DIY ‘bionic pancreas’ is changing diabetes care
> Hypoglycemia becomes symptomatic long before blood sugar is low enough to result in death or serious debilitation and T1D patients know their symptoms well.

Often times in an acute setting, yes. However patients who have had diabetes (T1 or T2) for a long time often lose a lot of their hypoglycemia sensitivity and symptoms. It's not nearly that simple.

et2o··on Superconductor news: What’s claimed, and how strong the evidence seems to be
I believe that most of the lead used today is a by-product or co-product of mining other more valuable metals like Zinc and silver. Lead is quite abundant in the Earth's crust and found in easy to access deposits.

I think >80% of the current industrial use of lead is for batteries. It's probably still in the top ten most mined metals by dollar value and definitely by mass.

et2o··on Tea as Hepatoprotective Agent: A Revisit
Fascinating. Thank you for sharing. I’m glad you were able to arrive at a diagnosis. I’m sorry to hear it was such an odyssey. I wonder how many other patients like you we are missing.
et2o··on Tea as Hepatoprotective Agent: A Revisit
Thanks for sharing. I’m a doctor. If you don’t mind sharing, out of curiosity how were you diagnosed with this? Not one of the primary immunodeficiencies I see tested, but I’m not a medical geneticist or pediatrician.
et2o··on FedEx Accused of Largest Odometer Rollback Fraud in History with Used Vans
It is not allowed prior to purchase
et2o··on Sony PlayStation 2 Development Kit (2020)
What even is a developer MacBook? Any applied computer can be used
et2o··on The Most Efficient Car Ever Created? Mercedes EQXX [video]
Interesting he calculates the theoretical maximum for efficiency will be around 260 MPGe
et2o··on Decolonization of the curriculum is the revenge of administrators
Addressing his specific point that “decolonization” of the curriculum in medicine is “dangerous” - As a practicing physician, I strongly disagree. I think the author likely has a completely inaccurate idea of what a medical curriculum even is, as I cannot reconcile most of what he is saying with what I’ve seen at several of the top medical training places in the country. Decolonization of medical curriculum in general is important as our euro-centric view of disease often ends up dramatically hurting minority individuals. This runs from obvious things like making sure physicians have pictures of rashes on melanotic (dark) skin in textbooks to more difficult things like incorporating non-European ancestry individuals in massive genetic studies and not simply discarding their genetic info (as has been done for a lot of large population studies historically).
et2o··on Why Tesla removed radar and ultrasonic sensors [video]
For the specific task of (for example) cooking a steak it’s not hard to envision a computer vision algorithm coupled with a model with a some basic knowledge of the system (ambient temperature, oven/stove temperature, time cooking, etc.) doing an excellent job.
et2o··on Students break acceleration world record for electric vehicles
This was the basis of a very famous F1 car in the 1970s. It was ultimately banned.
et2o··on Rapid nasal saline irrigation to reduce severity in high-risk Covid+ outpatients
Use of the CDC dataset as controls for a non-randomized trial is very problematic. Hard to know what to make of this at all. It has a modicum of bioplausability but I don’t think my posterior probability estimate of effectiveness has changed at all after reading the paper.
et2o··on Wikipedia is not short on cash
Truly an unnecessary dig at oncologists. If that happens it is not frequent. The more relevant association for clinical oncologists would be ASCO, which has its annual conference in Chicago this year.
et2o··on GM created a new energy business to sell batteries and solar panels
I don’t fully understand the appeal from the manufacturers’ side for in-home batteries and solar. We don’t expect houses to have their own coal powerplants or nuclear generators; why is renewable energy different?

Single family housing is becoming a smaller segment of the market as time goes on; those who rent apartments or own condominiums have little say in how their electricity is delivered as well.

et2o··on Effect of Colonoscopy Screening on Risks of Colorectal Cancer and Related Death
The problem with this study is that the analysis is based upon intention to treat. Only 42% of those who were randomized to get a colonoscopy actually got one. The cancer incidence was 18% lower among all people who were invited to get a colonoscopy. If we assume rate among people who were invited to get a colonoscopy but did not go through with it is the same as the rate of people who did not get a colonoscopy then the cancer rate would be more like -2/3 among those who got a colonoscopy.
et2o··on Emirates statement on operations at London Heathrow
This is a week old. Emirates did agree to cap passengers: https://liveandletsfly.com/emirates-heathrow-compromise/
et2o··on Food-seeking behavior is triggered by skin ultraviolet exposure in males
There is also some mouse experimental data
et2o··on Ohio State University secures trademark for use of the word 'THE' on clothing
That's not true at all, though. Y9u can absolutely do that as long as it's not in red and grey and sold in places customary to collegiate athletics.
et2o··on Volume of an n-ball
Fascinating observation. Thanks for sharing. Given that this problem space still exists I wonder what the best approach might be other than taking the mean
et2o··on NY Senate Bill S5474 proposing a universal single payer health plan for NYers
Nice. Yeah maybe this will be a win. I’m overall more for it than against it. Just think there are some downsides. Glad to hear you have had a good time on the NY State insurance. Is it Medicaid? Langone actually has the best (most private) payor mix of any of the hospitals in NYC, I believe primarily from geographic reasons. Did you get to compare to Bellevue at all? Curious on your perspective there. Hope you’re doing okay.
