atahanacar··on Using an 8K TV as a Monitor
I use a 50" 4K TV as my monitor. It's mounted on a long TV mount that can bend at 3 points, one near the wall, one near the TV and one in the middle. Gives me great freedom. One warning to people who want to do the same: make sure your mount has a way to rotate (around the screen's surface normal) the TV as the weight of it will make it sag.

Nice to see a fellow MD (very possibly older and more experienced than me) on HN.

>he totally forgot about this event and is in complete denial.

I can never understand this, especially with well educated people like your father or mine. I can't get mine to agree to go see a doctor (other than me - he doesn't believe me when I tell him something about medicine) for anything, even when there are obvious problems with his health.

Definitely possible. Blood pressure fluctuates during the day. Activation of the sympathetic nervous system causes the BP to increase. So technically the measurements were "correct", but it was misleading because when talking about BP we normally mean "resting BP".

Even with a catastrophically high measurement, no doctor would diagnose with a single data point. At worst, they would ask the patient to measure at home multiple times a day, after teaching the correct method of measurement. At best, they would do an ambulatory monitoring.

>I’ve never seen a discussion how ‘reactive’ one is physiologically

Then you have never looked for it. This is pretty basic stuff taught in the very first year of the medical school.

>when stressed rushing to a doctor’s office visit

Even has a name: white coat hypertension.

>I suspect blood pressures varies wildly through the day, and this variation depends on a person’s physiology.

Yes it absolutely does. Just like your heart rate varies throughout the day, your BP keeps changing as well. That's why we like to measure it over 24 hours before any diagnosis.

>Still putting off colonoscopy

I hope you won't regret putting it off.

>They love to misdiagnose hypothyroid or diabetes so they can begin destroying your endocrines

Yes, my favorite pastime when I'm bored of treating "actual" diseases.

I fail to understand how a well-educated group of people (aka. HN) can be this against the scientific method.

Definitely increases my BP though. Imagine someone ignoring their own health problems because they believed what a HN commenter said.
atahanacar··on Commonly used arm positions can overestimate blood pressure readings: study
Literally the first year of medical school, we were taught to let the patient rest for at least 5 minutes before taking vitals, while also asking about recent exercises or caffeine intake. This reduces the likelihood of a mistake, but white coat hypertension is still a thing. That's why we also teach them/relatives how to correctly measure BP on their own and ask them to measure it at home, preferably after waking up before eating anything.
atahanacar··on Commonly used arm positions can overestimate blood pressure readings: study
It's not only easier, but the actual correct way of doing it. That's why your doctor recommended it.

>This is a standard medical test I have completely given up on any doctor to perform accurately. I do it myself at home once or twice a month. I do it with the same device, in the same chair, at the same desk, the same time of day, after I’ve ate and drank the same thing.

You are assuming the average patient is this careful about measuring their BP, or anything about their health. You are also assuming the average patient measures their BP correctly, which is obviously untrue as evidenced by some other comments on this post. You are also assuming patients always tell the truth about their own measurements.

>We don’t need doctors with extremely limited datasets to do this and try to find obscure correlations for us.

I don't understand what you mean by this. None of us finds obscure correlations with limited datasets. We don't diagnose someone over a single BP measurement.

atahanacar··on Commonly used arm positions can overestimate blood pressure readings: study
>This gives an accurate reading and is often DRAMATICALLY lower

Just because it gives lower results doesn't mean it's more accurate. I can raise my arm during measurement or use a tourniquet above the cuff and get a lower result. That doesn't mean the measurement is accurate at all.

There are standardized procedures on how to measure BP. Your "accurate" method is not one of them.

Yet another medical topic being discussed on HN, with comments full of disinformation and skeptics that think they've noticed something new that doctors have missed. Remember people, don't take medical advice from HN.

atahanacar··on The Case for Hypochondria
>They seem to think that if the prevalence of a disease in the general population (or a specific patient's age/sex/racial demographic) is low, then the probability of someone presenting with signs and symptoms of the disease having it is also low

Because it is also actually low. Signs and symptoms aren't exclusive to specific diseases.

atahanacar··on Why does current flow the opposite way from the electrons?
What you are describing is a meme in my country, used to make fun of religious anti-evolution people who claim "evolution is only a theory and not a proven law, thus doesn't exist".

We call gravity "yer çekimi", which literally means "the pull of ground". The meme is "Ya yer çekimi yoksa da gök itimi varsa?" which translates to "What if the gravity doesn't exist but sky-push does?".

atahanacar··on Alarms in medical equipment
>I’ve seen nurses make mistakes several times because the equipment is too confusing. Once, I had to page the nurse myself because the IV they thought they set up was not functioning and I was able to discern that from the screen on the IV machine (which said one particular drug was not active) but they had not noticed

This doesn't sound like the equipment's fault.

atahanacar··on Moderna mRNA-4157 (V90) news for head and neck cancer patients like me
>problem of incentives

I don't see the problem here. In med school, the first thing we're taught is "primum non nocere". Of course it makes sense to penalize even if no harm is done to patients, if the methodology of testing is wrong or unethical.

> it's socially acceptable to violate ... ethical norms during an emergency

Not exactly. You aren't violating ethical norms, the ethical norms themselves allow or even "force" you to change priorities in emergencies. I would say "It's ethically acceptable to violate social norms during an emergency" fits better.

This is medical ethics 101. I don't have the time right now to explain it, but I will leave some keywords if anyone is interested in reading about it: therapeutic misconception, vulnerable groups, medical vulnerability. Related to your point (c): clinical equipoise.
atahanacar··on Why are bidets just now getting popular in America?
You can, but that doesn't mean everyone gets to enjoy it. And I'm not specifically talking about bidets. There are many convenient things used daily in Europe and Asia that are extremely rare in USA.

atahanacar··on Why are bidets just now getting popular in America?
Cultural differences?

America is very backwards and hilariously underdeveloped in some areas especially in day to day life. The fact that the parent comment calls toilet paper "sandpaper" is another example.

Because non-web applications are always very efficient and high performance, right?

The problem isn't the technologies available to us. Majority of devs just have no desire to write efficient code.

atahanacar··on Why are so many young people getting cancer? What the data say
>This is known as the Otto Wartburg effect

No it isn't. Warburg effect is observed in cells as a result of cancer.

>Metabolic therapy is tremendously successful in eradicating cancers even in later stages.

[citation needed]

Every time anything medical gets posted in HN, the amount of disinformation and bad medical advice is insane. It's easy to imagine (because it keeps happening over and over) a newly diagnosed cancer patient reading your comment and declining chemotherapy because apparently "keto diet beats cancer".

atahanacar··on Stable Diffusion 3
This isn't a valid concern in my opinion. Photo manipulation has been around for decades. People have been drawing other people for centuries.

Also, where do we draw the line? Should Photoshop stop you from manipulating human body because it could be used for porn? Why stop there, should text editors stop you from writing about sex or describing human body because it could be used for "abuse". Should your comment be removed because it make me imagine Taylor Swift without clothes for a brief moment?
