Why do some people lose substantial weight with GLP-1-based medications while others see more modest results?
A Mayo Clinic study offers a potential answer by identifying a distinct biological subtype of obesity that responds especially well to tirzepatide, a medication that mimics two naturally occurring hormones involved in appetite and blood sugar regulation, moving the field closer to precision medicine for obesity.

Scientists at Stanford Medicine have proposed an explanation for the rare cases of myocarditis that can occur after mRNA COVID-19 vaccination. The research points to a two-step inflammatory process involving the cytokines CXCL10 and IFN-gamma.
According to the study, vaccine-activated immune cells, particularly macrophages, produce high levels of CXCL10. This molecule then stimulates T cells to release IFN-gamma, creating a potent inflammatory signal that can damage heart muscle cells. The team confirmed this pathway through experiments using human heart tissue models, immune cells, and mice.
Importantly, blocking CXCL10 and IFN-gamma reduced signs of heart injury in laboratory models while largely preserving the protective immune response generated by the vaccine. The researchers also tested genistein, a natural compound found in soybeans, which showed anti-inflammatory effects in the models, though further clinical studies are required.
Myocarditis following mRNA vaccination is very rare, occurring in approximately 1 in 140,000 people after the first dose and 1 in 32,000 after the second, with higher rates observed in young males. Most cases are mild and resolve with full recovery. The study notes that COVID-19 infection itself carries a significantly higher risk of myocarditis, roughly 10 times greater than vaccination.
This work may inform the development of safer future mRNA vaccines while underscoring the established benefits of current ones in preventing severe COVID-19 outcomes.

@lifemiles unable to add my Lifemiles award flight PNR to United Airlines app. Is there another PNR that wasn't provided when I created the reservation? Thank you.
Watch this video showing how smooth reducing a dislocated shoulder is after an Interscalene Nerve Block.
Keep an eye on the shoulder and look how easy it pops back into place while he feels no pain.
This is why I haven’t had to do a sedation for shoulder dislocation in years.

@Austen One should feel eternally grateful for not having to deal with a 30 year fixed at a rate of 18% like back in the 1980s. Now that's scary! Is a dent even made on the principle in that case #puckerup
