Inflammaging: Brian Andonian, Sara LaHue, Joe Hippensteel

Six years ago we had John Newman on GeriPal to talk about Geroscience (Song choice Who Wants to Live Forever by Queen, perfect selection). John explained the basics of geroscience, what is it, what are the key theories in geroscience, what is senescence, why people who provide clinical care for older adults should care about geroscience, and potential therapeutics like metformin and rapamycin.

Today we bring on three rising stars in Geroscience, Brian Andonian, Sara LaHue, Joe Hippensteel, to talk about one of the key pillars of Geroscience: inflammaging. We use this terrific paper they published in Geroscience as a springboard. We discuss:

• What is inflammaging? Chronic progressive low grade inflammation with aging.

• I try to get one of them to stake a claim that inflammaging should be the organizing principle of geroscience

• How does inflammaging operate in rheumatologic conditions like rheumatoid arthritis (Brian), neurologic conditions like traumatic brain injury (Sara), and critical illness (Joe). We talk about Post-ICU Syndrome (PICS) and relate inflammaging to our prior podcast with Wes Ely about his book Every Deep Drawn Breath. We also talk about how inflammaging is not just a factor in chronic conditions like diabetes or inflammatory bowel disease, which make intuitive sense, but also in acute conditions, like sepsis or traumatic brain injury in older adults.

• The state of the science on clinical and research tests for inflammaging - ready for prime time? What is the state of the science for therapeutics? Why should some anti-inflammatory therapeutics make us nervous in frail older adults? Inflammation developed evolutionarily for a reason. E.g. tthink of drugs that wipe out the immune system.

• The outsized discrepancy between non-FDA products marketed to consumers as anti-inflammaging and the state of academic Geroscience. We announce GeriPal's new lineup of skin care anti-inflammaging products!

• We discuss lifestyle interventions such as exercise, meditation, caloric restriction and intermittent fasting, and strength/resistance training.

• \We recognize the efforts of Clin-STAR in bringing together multidisciplinary aging researchers to advance aging research, including our guests.

And what a joy to sing Billy Joel! Here's a link to the documentary I mentioned, which is on my list to see.
