Congratulations to #Brazil on becoming the first country in South America – and largest globally – to eliminate mother-to-child transmission of HIV. This achievement shows that elimination is possible with timely diagnosis, appropriate treatment, and access to maternal health services and a safe delivery.

Have you ever imagined being at one of the top surgical conferences in your country?

Our #MetaMasters arrived the last weekend in Rio de Janeiro to share their research work at the Brazilian Congress of Surgery, the largest and most prestigious surgical meeting in Brazil, bringing together thousands of surgeons, researchers, and students.

We couldn’t miss it! We're so proud of this team! 🚀🇧🇷

Postoperative delirium is a common complication following cardiac surgery.

This Bayesian network meta-analysis of RCTs assessed the effect of pharmacological interventions.

It found dexmedetomidine with melatonin was the most effective.

What if you could turn a concept into a structured research idea in just 4 steps?

That’s what the Medical Research Hackathon is all about:

📘 Step 1: Learn about research methodology and five powerful methods for idea generation
🧠 Step 2: Apply it independently with hands-on activities before the event
🌍 Step 3: Join a global team & develop a research project proposal
💥 Step 4: Engage in the Hackathon weekend (July 26–27) with live classes and awards for the best ideas

1/The medulla is anything but DULL!

Does seeing an infarct in the medulla cause your heart to skip a beat?

Does medullary anatomy send you into respiratory arrest?

Never fear, here is a thread on the major medullary syndromes!
