Episode notes
Pauling As A Metaphor For Ideas
- Mervyn recalled Linus Pauling's mix of brilliant and eccentric ideas to illustrate many competing sepsis hypotheses.
- He used that to frame why many potential treatments (e.g., vitamin C) require careful testing.
Target Metabolism And Mitochondria
- Sepsis therapies must target different pathways: immune modulation, endothelium, and metabolism.
- Metabolic manipulation and mitochondrial protection are promising strategies to restart organ function.
Phenotypes Dictate Steroid Response
- Patients show hyper- and hypo-inflammatory phenotypes, and therapies help one phenotype but harm another.
- Precision phenotyping is essential to choose treatments like steroids safely.
