Got It! How beautiful! #Sar2667 #Asteroid

I cannot eay this enough. A 'negative' tumour marker result NEVER excludes malignancy and a 'positive' never diagnoses malignancy in its self. And yes, this includes CA 125 and PSA. Tumour marker fishing is also a bad idea. Pre-test probability is extremely important.

For doctors, most diagnoses come from the history and examination. In many non-medical pathways, it can feel like the reverse: very little diagnosis from history/exam, and a heavy reliance on tests or onward referral, sometimes with no working diagnosis at all. If someone doesn’t understand what history and examination are for, it’s easy to skip them and default to “do tests” or “admit/refer so a specialist can diagnose”. The problem is that tests are then interpreted without a Bayesian “a priori” anchor. Without a pre-test probability built from a good story, a focused exam, and an understanding of how common conditions are so you’re left with results that can mislead, over-diagnose, or generate incidental findings. And if you don’t have a detailed grasp of disease patterns, you don’t know which questions to ask or what to look for to diagnose dementia or depression or diabetes or diphtheria. You can’t form a meaningful differential if you don’t know what’s common, what’s dangerous, and what’s discriminating. So the whole process drifts into secondary referrals and scanning as the default route to certainty. In parallel, some non-medical exams don’t require a deep knowledge base, so people are expected to “look it up” in real time under pressure. That isn’t the same as understanding, and it’s hard to expect consistently good outcomes from it. The final issue is that often one doesn't know what one doesn't know. This can lead to overconfidence or a very defensive position. Finally if you want to be seeing patients and making good diagnoses there is course for this called Medicine. Exams do expect knowledge.

Wait... this is controversial?? 🤦‍♂️

If you think extremism only comes from one side, you are part of the problem

This dog already saw this week's news and decided her dad didn't need to know all that. 14/10 (Sasha via ViralHog)

This is Parker. He will not eat until he receives a forehead kiss. 13/10 would give him so many smooches

SPACE FACT #6: Magnetars - a type of neutron star - have a magnetic field a TRILLION times stronger than the field surrounding Earth. This is so powerful that if you found yourself 1,000 km away from one, you would die as the electrons in your body's atoms would be distorted 🤯.

By far the most beautiful launch I’ve seen to date. This is one of thousands of photos I captured across 7 cameras. I can’t wait to share more with you!

If we can't afford to pay good doctors and all other NHS staff the global market rate to keep them here to maintain a world class health service, then we cannot afford the NHS. It's as simple as that.

My wife cheated on me at a Linkin Park concert but in the end, it doesn’t even matter.

From a patient point of view PAs AAs should be none existent, leave it to Drs and Nurses not forgetting the hard working healthcare support workers. Do the training necessary to become a qualified Doctor or Nurse.

Absolutely delighted to have passed the module 1 and module 2 exams for part 2 of the Royal College of Pathologists. I never have to sit another exam again! Now to becoming a fellow and paying the RCPath £600 a year 😂

USS Callister: Into Infinity was an absolute masterpiece! I loved it even more than the first one! As sequels go, that was pretty amazing. #BlackMirror #USSCallister

This is very concerning. X isn't perfect, but one thing it is good for is allowing everybody to speak their mind and critique, which is essential for organisations as important as this. You can't just run away from criticism - listen and do better (your job) instead.

I think my weather app is broke.

A positive troponin is not an MI. A positive BNP is not heart failure. A positive lactate is not sepsis. Please for the good of society can this be properly taught in all medical training programs?

SMASHED IT AGAIN @SpaceX and @elonmusk WELL DONE! Watching the future right in front of our eyes how incredible 🚀🌌

The fact that this is even being discussed is beyond belief 🤦🏻‍♂️

#SPACE #FACT #5: Neptune has the fastest wind speeds in the solar system of up to 1,200 mph! For comparison, the fastest non-tornado windspeed ever recorded on earth was 253 mph, recorded in 1996 during cyclone Olivia on Barrow Island, Australia. science.nasa.gov/neptune/nep…

#SPACE FACT! Neutron stars are so incredibly dense that a sugar-cube sized amount of it's material would weigh a BILLION tonnes on earth. Not a million... a BILLION TONNES. That is 1,000,000,000,000 kg. This fact weighs me down.
