Hospitals in the Capital are overwhelmed.
This isn’t an exaggeration.
Here’s why:
Successive Conservative governments have intentionally underfunded the NHS.

You gotta think about this one carefully!
Imagine you go to the doctor and get tested for a rare disease (only 1 in 10,000 people get it.)
The test is 99% effective in detecting both sick and healthy people.
Your test comes back positive.
Are you really sick? Explain below 👇
The most complete answer from every reply so far is from Dr. Lena. Thanks for taking the time and going through
You can get the answer using Bayes' theorem, but let's try to come up with it in a different —maybe more intuitive— way.
👇
Here is what we know:
- Out of 10,000 people, 1 is sick
- Out of 100 sick people, 99 test positive
- Out of 100 healthy people, 99 test negative
Assuming 1 million people take the test (including you):
- 100 of them are sick
- 999,900 of them are healthy
👇
Let's now test both groups, starting with the 100 people sick:
▫️ 99 of them will be diagnosed (correctly) as sick (99%)
▫️ 1 of them is going to be diagnosed (incorrectly) as healthy (1%)

Why can cefepime cause neurological toxicity?
And why is renal failure the main risk factor for this complication?
The answer requires us to learn about cefepime's structure and why it unexpectedly binds to a certain CNS receptor.

Let's establish a few facts about cefepime:
🔺4th generation cephalosporin antibiotic
🔺Excretion = exclusively in the urine (mostly as unchanged drug)
🔺Readily crosses the blood-brain barrier (so it easily accesses the brain)
https://t.co/rjYG1BfGPR
3/
The first report of cefepime neurotoxicity was in 1999.
A patient w/ renal failure received high doses of cefepime and then developed encephalopathy, tremors, myoclonic jerks, and tonic-clonic seizures.
✅All symptoms resolved after hemodialysis.
https://t.co/u7JLVitQpp
4/
Cefepime neurotoxicity is surprisingly common, occurring in up to 15% of treated critically ill patients (w/ symptoms varying from encephalopathy to seizures).
💡The main risk factors = renal failure and lack of dose adjustment for renal function.

5/
What about cefepime induces neurotoxicity?
One clue is that it's not the only antibiotic that causes neurotoxicity, particularly seizures.
This actually is a class effect w/ other beta-lactam antibiotics (including penicillins and carbapenems).
