  1. Epstein Files: A Functional Medicine Response

    FEB 11

    Epstein Files: A Functional Medicine Response

    The continued release of the Epstein files has sparked difficult but necessary conversations across the medical, longevity, and wellness communities. In this candid and deeply reflective episode of New Frontiers in Functional Medicine, Dr. Kara Fitzgerald sits down with Dr. Sara Szal and Dr. Brad Jacobs to explore what this moment calls forward from clinicians — ethically, professionally, and personally. Together, they discuss: • Medical accountability and the responsibility that comes with influence • The ethical obligations of physicians and mandated reporters • How the medical system has failed vulnerable adolescents — especially young women • Power dynamics, patriarchy, and the culture of silence • Trauma, ACE scores, and measurable impacts on long-term health • What practitioners can do differently starting now This is a thoughtful, clinician-focused conversation about integrity, trauma-informed care, and the role healthcare providers play in protecting and supporting patients. If you care about the future of ethical, patient-centered medicine, this is an important listen.

    Platelet-Derived Exosomes in Aesthetics: Data, Safety, and Real-World Use Cases

    Exosomes are becoming one of the most talked-about tools in regenerative medicine, but not all exosomes are created equal. In this episode of New Frontiers, Dr. Kara Fitzgerald talks with Alisa Lask, CEO of Plated Skin, about the science behind platelet-derived exosomes and why their signaling pathways matter for repair, renewal, and changes in skin appearance. We explore how discoveries in cardiology led to this technology, what early clinical studies are showing, and why source and preparation are critical when evaluating any exosome-based approach. A clear, grounded look at a fast-moving field for clinicians who want to understand what’s real, what’s emerging, and what deserves attention next. Full show notes + references: https://www.drkarafitzgerald.com/fxmed-podcast/ GUEST DETAILS Alisa Lask is the CEO of Rion Aesthetics, where she is driving innovation in regenerative aesthetics with platelet-derived exosomes and leading research in areas like hair restoration and skin appearance. She also oversees (plated)™ Skin Science, a medical-grade exosome skincare line distributed through aesthetic providers. Alisa previously held senior roles at Galderma, Allergan, Zimmer-Biomet, and Eli Lilly, and she serves on the Board of Directors for CollPlant.

THANKS TO OUR SPONSOR (plated)™ Skin Science: http://platedskinscience.com/ Plated Skin Science translates the discovery of Dr. Atta Behfar, M.D., Ph.D., Director of Mayo Clinic’s Van Cleve Cardiac Regenerative Medicine Program into the first shelf-stable skincare line using regenerative, platelet-derived exosomes. These aren’t generic exosomes; they’re a specific class shown in peer-reviewed trials to regenerate skin's appearance by improving the look of wrinkles, pigmentation, luminosity, and overall skin quality. It’s an elegant approach to visible signs of skin aging, recognized by Time as a Best Invention of 2024 and now used in more than 2,000 medical practices.

    The Hidden Immune Signal Accelerating Aging & the Beta-Glucan That Fixes It

    Beta-glucans might be one of the most overlooked levers in immune resilience, and that has major implications for longevity. Talking with my long-time friends and colleagues Drs. Bob Rountree and Chris D’Adamo reminded me just how powerful this molecule truly is. The clinical reach here is stunning, from immune aging and cancer support to vaccine response, gut–brain effects, and overall resilience. What struck me most is how beta-glucans help the innate immune system respond more effectively over time, from overtraining and chronic infections to vaccine responsiveness. Clinicians really need this on their radar. I think you’re going to find this conversation eye-opening. ~DrKF Check out the show notes at https://www.drkarafitzgerald.com/fxmed-podcast/ for the full list of links and resources. GUEST DETAILS Bob Rountree, MD, is a leading figure in integrative and functional medicine with more than 40 years of clinical experience.
