In this podcast, the hosts cover a range of intriguing topics including transfusion thresholds in acute MI, COVID-19 rebound after treatment with nirmatrelvir, the prevalence of iron deficiency, the ineffectiveness of oral phenylephrine, and the liberal vs restrictive transfusion strategy in MI. They also discuss challenges in transfusion decision making, highlight the unreliability of corrected calcium levels, and explore iron supplementation for anemia. A humorous introduction and calcium puns add entertainment to the episode.
The Mint trial showed that a liberal transfusion strategy may be beneficial for patients with type 1 MI, providing important insights into transfusion strategies in MI patients with anemia.
The recommendation to remove oral phenylephrine from over-the-counter cold medications highlights the need for more effective alternatives in the cough and cold medication market.
Deep dives
The Mint Trial: Restrictive vs. Liberal Transfusion Strategy in MI and Anemia
The Mint trial aimed to determine whether a restrictive or liberal transfusion strategy is more effective in patients with acute myocardial infarction (MI) and anemia. The trial found that at 30 days, there was no significant difference in death or MI between the two groups. However, subgroup analysis showed a potential benefit of a liberal transfusion strategy in patients with type 1 MI. The study provides important insights into transfusion strategies in MI patients with anemia.
The Removal of Oral Phenylephrine in Cold Medications
The FDA advisory committee recommended the removal of oral phenylephrine from over-the-counter cold medications due to its lack of effectiveness. The antiviral properties of oral phenylephrine have been questioned by pharmacology experts for years, but it has remained on the market. The recommendation to remove oral phenylephrine highlights the need for more effective alternatives in the cough and cold medication market.
The Impact of Transfusion Strategy in Patients with Acute MI and Anemia: The Restrictive vs. Liberal Transfusion Strategy Trial
The Restrictive vs. Liberal Transfusion Strategy trial was conducted to determine whether a liberal or restrictive transfusion strategy is more effective in reducing death and recurrent MI in patients with acute myocardial infarction (MI) and anemia. The primary outcome of death or MI at 30 days did not show a statistically significant difference between the two groups. However, a subgroup analysis suggested a potential benefit of a liberal transfusion strategy in patients with type 1 MI due to plaque rupture and vessel occlusion. Further research and consideration of individual patient factors are necessary for making transfusion decisions in this patient population.
Join us as we review recent practice-changing articles on transfusion thresholds in acute MI, COVID-19 rebound after treatment with ritonavir-boosted nirmatrelvir (PaxlovidTM), the prevalence of iron deficiency, as well as the debut of our new “corrections and omissions” section, in which we cover important knowledge updates on oral iron dosing and correcting serum calcium. And, find out why oral phenylephrine does not work and what you should prescribe instead for upper respiratory symptoms. Fill your brain hole with a delicious stack of hotcakes! Featuring Paul Williams (@PaulNWilliamz), Rahul Ganatra (@rbganatra), and Matt Watto (@doctorwatto).
