🔬 GIST Update: ASCO 2026 Peak trial shows bezuclastinib + sunitinib cuts progression risk by 50% vs sunitinib alone (mPFS 16.5 vs 9.2 mo)! Velzatinib also shows strong KIT mutation coverage in StrateGIST trials. Precision medicine is reshaping GIST care 🧬 #GIST #CancerResearch

H. pylori Screen-and-Treat Programs for Gastric Cancer Prevention — IARC Working Group Report https://t.co/skXkAtwXAe. Quality indicators for H.pylori programs are important. However, I think the origin of the problem lies in water access, ozonification and sanitation policies.

🧬 New in Nature: Inherited VSIG10L gene mutations disrupt esophageal cell integrity, raising the risk of Barrett's esophagus & esophageal cancer.
Chronic GERD suppresses VSIG10L expression ~3x, silencing the gene protecting the esophagus. new BRCA? #BarrettsEsophagus

⏹️ Are you still using clarithromycin or levofloxacin to treat #Helicobacterpylori infection?

⏹️ If so, current resistance patterns should give you pause.

⏹️Based on recent guidelines, they should only be used if there is demonstrated susceptibility.

What health condition do older adults fear most?

It’s not cancer, heart disease, or stroke.

It’s dementia.

And one factor speaks volumes about your future brain health:

Muscle health.

The research is clear:

1⃣ Adults 65+ with sarcopenia face 2.4x the risk of dementia.

2⃣ Men in their late 60s who lost more muscle over four years experienced faster cognitive decline.

3⃣ In adults in their early 70s, low muscle mass was linked to accelerated executive function decline over three years.

Muscle isn’t just about strength—it’s about protecting your brain.
