Radiology used to have something that was almost invisible because it was so routine: The reading room consult. Rounding teams came down. Surgeons pulled up their cases. Internists brought the scan that didn't quite fit the clinical picture. Sometimes the radiologist solved the problem. Sometimes the clinician supplied one piece of history that completely changed how the images were interpreted. And usually everyone simply walked away a little sharper. But something else was happening during all of those conversations. We were learning each other. As a radiologist, I learned what individual physicians cared about. I knew which findings mattered to a particular surgeon. Which measurements an oncologist was following. Which details a specialist wanted emphasized. What questions they were really asking, even when the order just said "pain." And they learned me. They knew who was reading their study. They knew they could walk in, point at something, challenge an interpretation, or ask, "What do you think?" That relationship created context. It created feedback. It created trust. And over years, it created a kind of institutional knowledge that never appears in the medical record. When radiology becomes a report produced by someone hundreds or thousands of miles away, we don't just lose proximity. We risk losing that entire feedback loop. The report may still be technically excellent. But the radiologist knows less about the physician. The physician knows less about the radiologist. The radiologist sees less of what happened after the report. And both sides lose opportunities to make each other better. The reading room was never just a room. It was where imaging became part of the clinical conversation. We should think very carefully before designing that conversation out of medicine. Inspired by a conversation yesterday with @PaleoOnc . Also @909One and @brianchiong .

Nearly 30 years in orthopedic surgery has taught me that giving someone more information is often one of the least effective ways to change behavior. I can explain arthritis, muscle loss, cardiovascular risk, metabolic health, and frailty until I am blue in the face, and usually… absolutely nothing changes. But... let's say a grandchild arrives. A trip involving hiking is considered. A spouse or close friend gets sick. Or perhaps someone simply realizes that getting off the floor has become much harder than it used to be. Suddenly, the same person who “couldn’t find the time” starts walking, lifting weights, and paying more attention to what they eat. I’ve seen this happen too many times to ignore it. Knowing what is good for us is rarely enough. We usually need a reason that matters to us now. So look carefully at your own life. What do you still want to be able to do five, ten, or twenty years from now? Who do you want to keep up with? What part of your life would bother you most to lose? Find that reason. Then go for the walk. Start there...

1/3 🧵 Preserving your ability to get off the floor is highly relevant to any of you 55+... You won't have issues now... You will in a few decades if you don't train this ability.

This is what operating under extreme pressure looks like. Surgeons at Kumamoto General Hospital in Japan were mid-operation when a 7.1 magnitude earthquake struck on the 28th of July. You can see the anaesthetised patient and equipment in the operating theatre swaying violently, but despite this, the surgical team held the patient steady and kept their calm.  All 4 scheduled operations were completed safely with zero injuries to patients or staff. Serious kudos to their composure and dedication 👏🙇🏻‍♂️

My wife and I got into it last night about the grocery bill. I pulled up an old Target order from February 2020. 28 items. $64.50. Added every single one back to the cart just to see. $158.30. Same 28 items. Same store. Same cart. $93.80 more. In five years. We didn’t buy more. Didn’t upgrade anything. Didn’t add a single extra item. Just needed the same things we always needed. They told us inflation was transitory. They told us it was under control. They told us the economy was strong. Our cart didn’t get any of those memos. 145% increase in five years. Not one member of Congress has looked at a grocery receipt in decades. And it shows.

40 out of 86 Brown students scored a perfect 100 on their midterm. Then the professor moved the final in person, and 22 of those perfect scorers never showed up again. He'd suspected AI cheating from the start. The take-home midterm was deliberately harder than usual, yet the class averaged 96 when the historical range is 65 to 80. Some answers contained odd phrasing that matched what ChatGPT produced when he ran the questions through it himself. Roberto Serrano has taught economics at Brown for 34 years. He filed no accusations. He announced the final would be in person, count for half the grade, and that if the two distributions didn't match, the final alone would determine grades. Then the exodus. 27 students never showed up. 22 of them had perfect midterms. Of the 59 who did show, 19 failed. Several signed the exam and turned it in blank. The average fell from 96 to 48, the lowest in the course's history. He never needed a plagiarism detector. The cheaters identified themselves by walking away. A grade distribution became a confession. Here's the part nobody's sitting with. Serrano proved it. He sent the distributions to Brown's dean and provost. The provost never responded. The academic committee's reply amounted to calling it "a wake-up call." The students who bailed before the final walked away clean. Every university in America is now grading two populations, students and students plus ChatGPT, on one curve. The honest kids in Serrano's class watched a 96 average get set by machines, then sat a real final against it. The cheaters lost nothing. That's the incentive structure now, and it grades itself.
NEW: Ivy League professor suspected AI cheating, ordered an in-person final, & saw average scores plunge from 96 to 48.

Can reopening a chronic total occlusion (#CTO) make the heart electrically less prone to #ventricular #arrhythmias? For years, small studies suggested the answer was yes. We analyzed 7,496 ECGs from 1,232 patients undergoing 1,520 CTO PCIs using automated Python-based signal analysis. Here's what we found... 🧵

When I lived in Montreal, a friend told me the craziest thing. He had discovered a bat sleeping in his closet. I marched him straight to the hospital to get rabies shots, and they gave it immediately. Even if you're not sure if you got bitten or scratched, any contact with them needs to be evaluated. Once you develop symptoms, death is almost certain. Early vaccination will save your life.

67 year old Cardiologist borrowing this to say to his 30 year old self… We see it all the time in structural heart disease.
Seven Things This 63 Year Old Surgeon Would Tell My 40-Year-Old Self I am 63 now, and I spend my days as an orthopedic surgeon watching how people's earlier choices show up in their bodies decades later. I see it in my college friends, high school buddies, and patients that I have known for 20+ years. If I could sit across from myself at 40, here is what I would want that man to understand. None of what follows is complicated, and all of it compounds over the decades… either against you… or in your favor. You are largely in control.

A 77-year-old marathon walker developed a headache. Over the next four months, she was seen by a nurse practitioner, a PA twice, a medical assistant, and an emergency room. She was given two Medrol dose packs, NSAIDs, and a prescription for fluoxetine after a PA decided she had anxiety. She had never actually seen her primary care physician. She had giant cell arteritis. A sed rate of 41 confirmed it, the moment her neurologist finally examined her, took her history, palpated her temporal arteries, and asked about jaw claudication. The patient told her neurologist: "if you think I need fluoxetine I'll be on it, but I don't think I'm anxious and this headache is just crazy." The structural argument matters more than the cinematic detail. Team-based care is sold as a solution to the physician shortage. The math runs the other way. If a physician is the diagnostic instrument that holds the differential together on a multi-system presentation in a 77-year-old, the marginal cost of putting that physician in the room at visit 1 is zero. The marginal cost of NOT putting that physician in the room across this case was four office visits, an ER visit, two courses of steroids that partially masked the inflammatory signal, a misdiagnosis of anxiety, an SSRI prescription, and a delay in identifying a vision-threatening time-sensitive diagnosis. The team did not save physician time. It spent physician time everywhere except with the patient. Reeta Achari, MD, a neurologist in solo private practice in Houston for 25 years, makes the operational case in plain terms. There is a physician shortage. The response has been to use physician time for documentation, prior authorizations, peer-to-peer calls, board recertification weeks, and electronic-record data entry. The response should have been the opposite. If there is a shortage of the diagnostic instrument, the workflow has to put the instrument in front of the patient, not behind four other people. Her own response was structural. She opted out of Medicare. She built a quarterly subscription practice with prices middle-class patients can afford and scholarships for long-relationship patients. New patients get a one to one-and-a-half hour intake. Follow-ups get 30 minutes. The model is not concierge. It is continuity, priced to clear. The diagnostic line from her conversation: "No physician touched her." Listen to the full conversation on The Podcast by KevinMD. Link in the replies. What does the cascade in your practice or your own care look like? Where in the workflow did the physician finally enter the room? #ThePodcastbyKevinMD

I’m so incredibly frustrated. We have an outbreak report for the cruise ship, published in NEJM, and great clinical, epidemiological, and genomic reporting, and… NOT A SINGLE MENTION OF VENTILATION/FILTRATION SETUP ON THE SHIP Folks, we keep doing this. A lot of MD/PhD coauthors on the “Andes Virus Outbreak Working Group”, and no one with expertise on mechanical systems. And no one on the team even thought to check or investigate it. It’s malpractice at this point, and I’m not exaggerating in my use of the term. I do investigations in buildings and if I failed to check the status of the mechanical systems I’d be sued. (It’s actually *the first* thing I check) @NEJM: see our report from The Lancet COVID-19 Commission on this in the thread. Include this in your reviews. Mandate this info in every outbreak investigation report. The reason I first called the doctor on the ship was because I wanted to see if he could get info on the ship’s systems before he left it, bc I knew the official investigations would miss it. Because they always do.
𝗣𝘂𝗯𝗹𝗶𝗰 𝗛𝗲𝗮𝗹𝘁𝗵 𝗔𝗹𝗲𝗿𝘁𝘀 𝗥𝗲𝗽𝗼𝗿𝘁: On April 27, 2026, a man (later classified as Patient 3 in the outbreak) was medically evacuated to Ascension Island from the Dutch-flagged expedition cruise ship 𝘔𝘝 𝘏𝘰𝘯𝘥𝘪𝘶𝘴; he had severe acute respiratory infection (SARI) and reported shortness of breath and fever that had begun on April 21. He had signs of pneumonia, although findings on chest radiography were unremarkable. While he was on Ascension Island, his condition worsened, and he was transferred to Johannesburg, South Africa, for ventilator support and intensive care. He was in shock and had acute respiratory distress syndrome; findings on chest radiography were consistent with atypical pneumonia. The differential diagnosis in this clinical context is very broad and includes atypical pneumonias, bacterial or fungal sepsis, and vectorborne diseases such as malaria or dengue. The diagnostic evaluation, including respiratory pathogen panels, malaria smear and antigen, fungal biomarkers, blood cultures, and legionella urinary antigen, was unrevealing. On May 2, the cruise ship had a total of 147 persons on board, including 88 passengers and 59 crew members, from 23 countries. As of May 13, 2026, a total of 10 cases had been identified (an 11th was subsequently reclassified as not a case), including 3 resulting in death (seen in figure). However, because not everyone on board was tested, 3 deaths among 10 cases may represent an overestimation of the case fatality ratio. All cases to date have been among passengers or crew on board the ship. Beyond the first 3 cases, 7 additional confirmed or probable cases have been identified. A German national (Patient 4) died from a SARI on May 2, and later testing in the Netherlands confirmed Andes virus (ANDV). Two crew members — the doctor on the ship (Patient 5) and an expedition guide (Patient 6) — were medically evacuated to the Netherlands, tested positive by PCR and sequencing for ANDV on May 7 and 8, respectively, and were in stable condition at the time of this report. Read “Andes Hantavirus Outbreak on a Cruise Ship, 2026,” which includes clinical details, case timeline, genetic sequencing of the virus, and unresolved transmission questions, by the Andes Virus Outbreak Working Group: nej.md/4uQDeMQ

🤷‍♂️ It's really up to circumstances outside of our control or knowledge at this point If 100 embers are scattered to the wind will one of them catch fire? 🔥 That's where we're at right now

It's widely accepted that hantavirus transmits from rodent excreta to humans via inhalation of aerosolized virus, so I don't understand why we're so reluctant to acknowledge the inhalation route for human-to-human transmission. nytimes.com/2026/05/14/healt…

An important measure of how much contact is required for transmission, and for how long, will come from passengers on the airplane that carried a critically ill cruise passenger who died shortly after the 4.5 hour flight to Johannesburg. Late this week, a flight attendant, with potential symptoms, tested negative.
Where is this “prolonged or intimate contact” coming from??? xitter.cf/j_g_allen/status/20525…

I was up last night with a STEMI until 4:30. For my entire career I’ve gone to work the next day with whatever sleep I could get. Not anymore. Today, I slept in and did chart work from home. You can’t fly an airplane or drive a truck if you’ve been up all night. Why should it be different for docs?

#Sharing For Learning Did you notice something? A subtle finding. Easily missed. Yet potentially fatal if overlooked. Miss it… and you may lose the patient. Recognize it early… and you save a life. What next??
