In episode, Chris and Mars zoom in on trace elements—those small but mighty players in surgical recovery and nutrition. Whether it’s zinc, copper, selenium, or even manganese, these elements pack a punch for your patients on Total Parenteral Nutrition (TPN) and are guaranteed shelf pearls for your exam.

🎙️ You’ll learn: ✅ Why zinc deficiency can tank wound healing and show up as that classic perioral/perianal rash (acrodermatitis!). ✅ How copper deficiency mimics B12 neuropathy and causes microcytic anemia unresponsive to iron. ✅ The link between selenium and cardiomyopathy (hello, Keshan disease!). ✅ Why a TPN patient with new hyperglycemia might actually be missing chromium. ✅ The Parkinsonian danger of manganese toxicity in long-term TPN. ✅ And quick hits on iodine, iron, magnesium, fluoride, and more.

Perfect for med students prepping for the surgery shelf or clinicians managing high-risk surgical patients.
