Welcome to #Scanuary

A month-long marathon of daily tweetorials on #POCUS and its utility in our clinical practice.

@salmannaeem217 and @drmohansai have done a fantastic job so far, sharing numerous clinical pearls.

For the next few days, I’m going to introduce you to my dear friend C-3POcus 🤖📟 — the emergency department ultrasound who will bring you tales from his long ED shifts.Image
Hi, my name is C-3POcus, your Emergency Department ultrasound machine.

I never sleep, but my day seems to restart around 8am when a new team walks in. I’m usually left at the side of a bed. Sometimes I get dumped in a storeroom with all sorts of weird equipment. Worse still, I’ve been abandoned in the sluice 😳.

Eventually someone comes looking for me—usually when I’m in a terrible state. They give me a quick wipe, clean the blood off my probes, remove old catheter equipment from my tray, and top me up with fresh ultrasound gel. Bliss ✨

It’s usually the same 3–4 doctors and nurses who take care of me. I can tell they love me—they carry me everywhere and introduce me to all their patients.
Let me tell you the story of a typical day for me in the ED… 🩺📟Image
By 9am, one of the registrars wheels me into Resus.
There’s a 70-year-old who came in overnight after a fall. Multiple rib fractures. Significant chest pain despite analgesia.

I knew what was coming next - He was about to get BLOCKED 💉

The only question was: SAP or ESP? Either way, I was ready to track that needle 👀

Rib fractures cause severe pain → hypoventilation, poor cough, impaired secretion clearance → atelectasis & pneumonia.

Opioids help, but come with problems: respiratory depression, constipation, delirium. If pain isn’t managed well, these patients get sick—fast.

That’s why multimodal analgesia matters. And a key part of that?
👉 Early regional anaesthesia to improve pain, allow early physio, and reduce complications.Image

You’re not as rational as you think

Smart people make dumb decisions all the time

Charlie Munger explained why, and how to fix it

Here's a thread on The Psychology of Human Misjudgement: Image
Charlie Munger spent decades studying why smart people make bad decisions.

He identified 24 standard causes of human misjudgement.

Let’s break down the most important ones: Image
1. Incentive Bias

People do what they're rewarded to do.

Not what’s right. Yes, even you.

Never underestimate how powerful incentives are. Image

Your emergency fund is costing you money.

The traditional "6 months in savings" rule?

It leaves $10,000+ in opportunity cost on the table for the average household.

Most people are either over-saved or under-saved. Both mistakes.

Here's the framework no one talks about ↓
The Traditional Rule Is Outdated

The advice: Save 6 months of expenses in a savings account.

The problem: Too much cash = inflation eats your wealth
Not enough liquidity planning = you tap retirement accounts in emergencies

There's a better way.
Example:

Household expenses: $5,000/month
Traditional advice: Keep $30,000 in savings (6 months)

Even in a 4.5% HYSA:
Earnings: $1,350/year

In a balanced investment account averaging 7%:
Earnings: $2,100/year

I think we're now able to build a pretty clear picture of the most likely mechanism of the train crash at Adamuz in Spain. Image
Image
Image
Image
1️⃣
The northbound Madrid train (a red Frecciarossa 1000 operated by Iryo) passes over a rail weld, likely fractured within its heat-affected zone, that breaks under the impact of the passing train.
2️⃣
The first 5 cars of the 8-car train pass safely over the break, but repeated impacts turn a break into a catastrophic rail failure, and the 3 rear cars of the northbound train are derailed as the rail shatters. Image

Anxiety isn’t just in your head.

It’s stored in your nervous system.

Here are 9 body-based ways to release it (without medication) 🧵

1. Cold water on your face. Image
Image
1. Cold water on your face activates the vagus nerve.

It triggers the mammalian diving reflex → increases parasympathetic (vagal) activity and slows your heart rate, which helps interrupt panic attacks.

Cold water also signals GABAergic release, giving you a quick, refreshing, invigorating feeling. It's a sure-fire way to interrupt negative thought loops.
2. Slow exhales stop the fight-or-flight response-- in seconds.

Long exhales increase respiratory sinus arrhythmia (RSA) and vagal calming. Your entire body relaxes, and visual clarity is restored.

This often increases HRV and shifts autonomic balance away from the fight-or-flight response.

Why does @ScottPresler push mail in voting in non-presidential elections? Because conservatives don’t show up to vote in them! If we don’t show up; we are to blame. Especially when judicial elections are on the ballot! We are being held hostage by radical leftist judges.
We had a chance here in PA but we F'ed it up. @Ginagina822 & @EarlyVoteAction worked their a$$es off & conservatives still had a dismal turnout!!! So, the Dems got their state supreme court justices retained for 10 more years!
It was critical to get the vote out but conservatives did not vote, as usual, in a non-presidential election. We have only ourselves to blame. Each & every conservative needs to make it a priority to register at least 1 voter & ensure they show up to vote! Drive them if possible

Hello! My next book "The Next World War: The New Age of Global Conflict and the Fight to Stop it" is out on January 29 from @headlinepg. Here are the top ten questions I've had about the book in recent weeks…
amazon.co.uk/Next-World-War…
@headlinepg The first is whether that war has already started. I get why people ask, and we are clearly moving into danger. But as I told this @Telegraph podcast,a true "world war" would be on a hugely larger level
@headlinepg @Telegraph The second is how likely I think that war might be. In the introduction, I put the prospect at 30-35 percent over the coming decade. I think that's higher than the first Cold War, which I've studied relatively deeply amazon.co.uk/Deterring-Arma…

1/About 1,500 active-duty soldiers, two infantry battalions of the Army's 11th Airborne Division, are under prepare-to-deploy orders for possible action in Minnesota. This means Donald Trump is actively contemplating invoking the Insurrection Act. Absent that, deployment of active duty members of the military is prohibited by the Posse Comitatus Act.
2/It bears repeating that the American military isn’t meant to be used for domestic law enforcement against American citizens, barring extraordinary circumstances that simply aren’t present here.
3/Trump could become the first President to direct the use of U.S. military forces against American citizens during peacetime. And he’s doing it in a situation where the “unrest” is mostly peaceful protests resulting from Trump’s efforts to inflame the city. The situation is hardly the kind of insurrection, domestic violence, or conspiracy the Act contemplates,

'Trump sent a letter to Norway’s prime minister Jonas Gahr Støre telling him that “considering your country decided not to give me the Nobel Peace Prize for having stopped 8 Wars PLUS, I no longer feel an obligation to think purely of Peace.”'

1/🧵theguardian.com/world/live/202…
Trump was never interested in peace, and the liar never stopped 8 wars, he just falsely claimed he did. All because of his demented racist hatred of Barack Obama, and he got something Trump will never have, a Nobel Peace Prize.
2/
Trump is America's very own Caligula or Nero for the modern age, a mad wannabe Emperor of a non-existent empire, making lunatic pronouncements, and he should be in a lunatic asylum for the criminally insane - for public protection.

You couldn't make this 💩 up if you tried.

🧵Stunning proof of the extent of cooperation between government officials and settlerorists.

This is an invitation to a Knesset conference honoring the contribution of prominent settlerorists to the ethnic cleansing of the WB. Image
MK Son Har Melelch, Knesset Vice chair, uses Elisha Yered's (her former advisor) picture in an invitation to a Knesset conference celebrating ethnic cleansing.

We wrote of Yered's involvement in terrorist activities last November, when 🇸🇬 joined 🇬🇧🇪🇺🇦🇺🇨🇦 & others in sanctioning him:
But Instead of prosecuting terrorists, Israel sponsors them, knowing the West & rest will stand by 🇮🇱.

Yered is of course not the only nationalist psychopath to be honored in this state-sponsored conference.

FairScale: The Future of Trust in Web3

Web3 promises decentralization, but it’s failing where humans matter most: Trust. Wallets are anonymous, reputation is scattered across forums, Twitter, and Discord. Every transaction can feel like a gamble. Builders get ignored, bots get rewarded, and opportunities slip through cracks.

Now, imagine a world where your on-chain actions, social contributions, and community engagement could be summed into a single, verifiable reputation metric. That’s exactly what @fairscalexyz is building. And with the help of @SuperteamEarn I've been given the opportunity to dive deeper into FairScale.Image
What Exactly Is Fairscale?
FairScale is a Web3 reputation protocol that computes a FairScore using on‑chain behaviour, social signals, and community proofs making reputation a verifiable, portable trust metric rather than an abstract concept.

It launched publicly in early 2026 with live processing of on‑chain transactions and is focused initially on Solana with multichain expansion plans.Image
Exciting Features Of Fair Scale

-FairScale uses a dynamic scoring model powered by neural networks

-It analyzes on-chain behavior, social activity, and community signals

-Distinguishes real contributors from opportunists

-Continuously evolves as your interactions grow

It's time to run the trend #MakeARRahmanHinduAgain also known as #MakeARRahmanDileepAgain

That is the only way Hindus are going to forgive AR Rahman for what he's recently said about Bollywood (or any other Indian film industry) having become "communal".

AR Rahman's real name is AS Dileep Kumar. Both his parents, RK Shekhar and Kasturi, were Hindus. He was 9 years old when Shekhar died. He was 18 years old when his sister was terminally ill & being a secular like most Hindus of that time, he attended Qadiri Tariqa, a Sufi school.
Having been deeply brainwashed by their propaganda for 5 years, he converted to Islam at the age of 23, then convinced his sister and mother to convert as well.

Soon, his mother became highly regressive that she would not allow any Hindu visitors if they had tilaks on foreheads.
