In this episode of the GeriPal podcast, we dive into the fascinating world of geriatric dermatology, or "GeriDerm," with two exceptional guests: Dr. Daniel Butler from the University of Arizona and Dr. Eleni Linos from Stanford University.

First, we tackle the big question: how do we keep our skin healthy as we age? I see this on a daily basis with my own skin, but I'm unsure what to do about it, including whether we all need to use sun protection and moisturizers, and if so, which ones?

Then we explore the lag time to benefit in dermatology by examining whether we need to treat every actinic keratosis and basal cell carcinoma aggressively, or whether there are cases where we can opt for watchful waiting.

We also explore chronic itch with Daniel, covering the three main sources of itch and how our management should change accordingly. Importantly, antihistamines were not a prominent part!

We finally asked Eleni whether artificial intelligence (AI) and digital tools can revolutionize the way we diagnose and manage skin conditions, especially in older adults.

For a deeper dive into the topic, check out these two papers that we talk about on the podcast

• Daniel's JAMA paper on Chronic Pruritus

• Elani's JAMA IM paper on Active Surveillance as a Management Option for Low-risk Basal Cell Carcinoma

Eric and I were delighted to be invited to Brazil to give a series of presentations in Sao Paulo at their annual geriatrics meeting. We met people doing important, interesting, and innovative work in Brazil and throughout Latin America. We got the audience to sing along, including (in another talk) the magnificent Brazilian song Sozinho by Caetano Veloso in Portuguese, with my son Renn playing guitar.

For our final talk, a podcast in front of a live conference audience, we asked our 3 guests, Eduardo Ferriolli, Marlon Aliberti, & Edison Iglesias to select a recent article to discuss. We talked about:

1. Intrinsic capacity (selected by Eduardo). What is it? What is it used for? How do you measure it? (hint ICOPE). Eduardo emphasized that intrinsic capacity is a positive aspect of aging, focused on potential rather than deficit. We asked him to work intrinsic capacity into George Kushel's famous analogy using the golden gate bridge to describe phenotypic frailty (pillars), deficit accumulation frailty (cable supports), and resilience (withstand stress of wind and cars). Eduardo says intrinsic capacity would be the car, and would vary by type of car and intended purpose. I loved Eduardo's selected article, which percentiles intrinsic capacity, in order to use within individuals to assess how they're tracking over time, and at a public health level, to identify regions or groups of people with lower intrinsic capacity. He draws the analogy to growth curves in pediatrics - if you're consistently at 80% - then drop off - your primary care provider should take notice and investigate/intervene.

2. Geriatric syndromes in hospitalized older adults (selected by Marlon). If intrinsic capacity is for primary care, our guests argue that the comprehensive geriatric assessment, which takes a long time to administer, should be reserved for specialist geriatrics. And yet, this paper finds that a limited shorter version of the comprehensive geriatrics assessment can document geriatric syndromes in hospitalized older adults. Accumulation of multiple geriatric syndromes is associated with increased mortality, and presents an opportunity for risk stratification, goals of care discussions, and intervention.

3. Advance care planning across Latin America (selected by Edison). Back around 2005, when Edison first heard about advance care planning, he says, "it sounded like science fiction." In Brazil, as with Latin America, medicine was highly hierarchical and patriarchal. Doctors knew best. The doctor decided. If there was no patient choice, why would there be a system to protect the decisions of patients made in advance? In the intervening years, Edison and others have worked to incorporate and adapt advance care planning to the Latin American context, which is much more focused on family-centered relational autonomy than individual, and incorporates spirituality to a much greater extent. Edison has been mindful too of not repeating the mis-steps of the advance care planning and advance directive movements in the US.

We took questions from our audience and sang "Imagine" in Portuguese together. Enjoy!

Lynn Flint and Anne Kelly join as hosts in a reprise of last year's ask us anything format. Thank you for sending in your terrific questions! Lynn and Anne condensed them to about 20, and we ran through them rather rapid fire. Also on fire? Our mouths. As with our 300th episode, we did this Hot Ones-style. Every few questions, we had to eat a chicken wing slathered in hot sauce. The hot sauces got progressively hotter, though as we discovered, the ordering may have been a littttttle bit off. Still, by the time we hit the really hot ones, our mouths were on fire, we were blowing our noses, gulping down milk, and terrified of what the next hot wing would bring…

We covered so much in this podcast, including:

• Coffee or tea? What jokes do you make with patients?

• Where do we see ageism?

• Why are we still advocating for advance care planning?

• Concerns about expansion of medical aid in dying

• Should doctors reveal that they're using AI in clinical care (thanks for the question mom!)

• The future of geriatrics and palliative care

• What we'd do differently about the podcast if we could start over, or what we could do that is new going forward. Surprises in terms of who is listening, our audience.

• Ideas for others to build community as we do at GeriPal

• Influence of our own spirituality and religion on our clinical practice

• Lasting practice changes from prior podcasts, or from Covid experience

• Why PC in the ED hasn't taken off

• And more!

Looking back on 10 years and 400 podcasts, Eric and I are filled with gratitude for you, dear listeners. You sustain us. You keep us going. Please stay involved, send us messages about show ideas, and introduce yourself to us at national meetings.

Thank you!
