1:07:49

Join me for a fascinating conversation around an exciting breakthrough in dementia detection that’s offering real hope for early intervention. Dr. Hans Frykman, Chief Scientific Officer at Neurocode Laboratories, is here to share groundbreaking insights into cutting-edge biomarkers that can identify pathology associated with Alzheimer's disease before symptoms even appear. What’s even more fascinating is how these same tools are revealing neuroinflammation caused by infections, including COVID, Lyme disease, and mold exposure—issues that are incredibly relevant in functional medicine today. The assays Dr. Frykman and his team have developed, and continue to research, are transforming the way we think about diagnosing and addressing neurodegeneration. We’re talking about a potential game-changer that allows us to intervene earlier, reverse damage, and ultimately improve the trajectory of these conditions. This is an extraordinary time in science and medicine, and the work we’re discussing today is at the forefront of it all. Don’t miss out on how this could reshape your practice. ~DrKF Check out the show notes at https://tinyurl.com/2t55s3y3 for the full list of links and resources.

A Fresh Take on Exposomics: Resiliency Factors That Offset Environmental Risks 1:09:32

5 weeks ago1:09:32

1:09:32

It’s very difficult (often impossible) to completely avoid many of the environmental toxins that can cause harm - like air pollution and forever chemicals that contaminate our water and food supply. But Drs. Bob and Rosalind Wright at Mount Sinai have a hopeful solution to this dilemma. They are pioneering the study of “resiliency factors,” not just “risk factors,” that can offset the risks of harmful exposures. It’s a fresh and welcome take on exposomics that I am very excited to share with you. For instance - did you know that omega-3 intake during pregnancy can protect against the development of asthma in the child, even if the child is exposed to known risk factors for asthma? Or that positive relationships (ones that create a sensitive, positive, caregiving environment) have been shown to potentially mitigate the effects of environmental toxins? As a practitioner, I am always looking to empower patients with real solutions to the health challenges we inevitably face and I hope you enjoy this conversation as much as I did. ~DrKF Check out the show notes at https://www.drkarafitzgerald.com/fxmed-podcast/ for the full list of links and resources.

Wise Chair of Environmental Medicine at Mount Sinai and co-founder of the Institute for Exposomic Research. His research links environmental exposures, like those tracked in the PROGRESS cohort, with the developmental origins of diseases. Dr. Rosalind J. Wright is Dean for Public Health at Icahn School of Medicine and Co-Director of the Institute for Climate Change, Environmental Health, and Exposomics. A pioneer in environmental health, she studies how early-life exposures influence chronic diseases and has been NIH-funded for over 23 years.

The brain’s ability to recover after trauma is astonishing—and often overlooked in conventional care. In this episode of New Frontiers in Functional Medicine, I sit down with Dr. David Musnick, a long-time friend and brilliant clinician, to explore how we can unlock the brain’s full potential for healing. Dr. Musnick challenges the standard of care for traumatic brain injuries and post-concussion syndrome, introducing a functional medicine approach that integrates advanced tools like Frequency-Specific Microcurrent, targeted nutritional strategies, and personalized interventions. His insights into the stages of recovery, the importance of addressing neuroinflammation, and the role of the gut-brain connection were a true "aha" for me. We also dive into groundbreaking methods for reversing secondary brain damage, a concept that could change everything for patients and practitioners alike. This conversation is packed with actionable takeaways and hope for those navigating brain injuries, cognitive impairment, or persistent post-concussion symptoms.

An HRT Revolution is Underway. Ready to Individualize Recommendations for Hormone Health? 1:05:12

18 weeks ago1:05:12

1:05:12

For anyone who has been paying attention, you may already know that the takeaways related to hormone replacement therapy (HRT) from the original Women’s Health Initiative (WHI) study have been completely overhauled. It’s about time! As a result, it’s not an understatement to say that we are in the midst of a total transformation in hormone replacement therapy (HRT) and it’s essential that as providers we (1) get up to speed on the nuances of the new interpretations and (2) learn how to personalize the guidance we give. Dr. Allison Smith, from Precision Analytical, is really a bright, guiding light in this new era of hormone care. She joins me in this episode of New Frontiers to start to unpack some of those important considerations and share resources for where practitioners can learn more. She explains why more detailed hormone metabolite testing can provide answers to hormonal symptoms when standard serum measures of testosterone and estrogen are “normal.” She also shines a light on the need for understanding how our patients are metabolizing hormones, especially if they are on HRT as well as to optimize their long-term cardiovascular, bone, skin, and brain health. This is indispensable listening and I’m sure you’ll enjoy this conversation as much as I did. - DrKF Check out the show notes at https://www.drkarafitzgerald.com/fxmed-podcast/ for the full list of links and resources.

Are You a Fast Metabolizer of Omega Fatty Acids? Lessons from a Legend 1:08:59

21 weeks ago1:08:59

1:08:59

It’s not overstating it to say that I have cited Dr. Artemis Simopoulos’ work in virtually every lecture I have ever given that included the topic of omega-3 fatty acids. She is an incredible human being, indomitable NIH researcher, and absolute legend in her field. In our conversation on New Frontiers, Dr. Simopoulos reviews those essential truths about the evolution of our dietary intake of omega-3 vs. omega-6 fatty acids, the increase in ultra-processed food consumption, and how these play into our health landscape today. She also pulls on some particularly interesting threads around genetic variability in our ability to metabolize fatty acids and the implications of this for inflammatory conditions (of course, almost all chronic diseases have an inflammatory component). This is especially relevant for “rapid metabolizer” populations that tend to over-produce prostaglandins and leukotrienes, compared to resolvins, when exposed to a standard American diet. I know her insights will inform how you personalize your recommendations. - DrKF Check out the show notes at https://www.drkarafitzgerald.com/fxmed-podcast/ for the full list of links and resources.

The centrality of gut health in total body health and aging means it’s a key topic for us to keep revisiting and updating our knowledge on. For instance, how confident do you feel about interpreting analytical indices such as phyla distribution, dysbiosis index, diversity score, as well as the myriad bacterial populations that can be resident in the GI tract? Join me and Dr. Julia Malkowski as we dive into advanced stool testing and how the insights gleaned from the GI360 test can tell us a lot about our patients’ health and lifestyle (ever wondered how the carnivore diet, long-term use of GLP-1 agonists, or chronic stress impact the gut?). We also explore keystone bacterial species and their impact on systemic health, what is better than fiber for increasing microbiome diversity, different testing methods including the impressive MALDI-TOF Mass Spectrometry Technology and a ton of clinical pearls on tackling those report findings in clinical practice. There is something for everyone in this excellent conversation with Dr. Julia Malkowski, from the newly-minted to the seasoned functional medicine practitioner, and health-savvy consumers too.

Promise and Controversies: State of the State of Longevity Science with Matt Kaeberlein, PhD 1:25:09

25 weeks ago1:25:09

1:25:09

It's important to me to include a variety of voices in the sphere of aging and longevity, and Matt Kaeberlein PhD is certainly one that I appreciate for his tempered and rational arguments. I value his insights and his work with other scientists who are tussling with the challenging questions and research interpretations in this field. We are at this extraordinary inflexion point where scientists are debating the very definition of aging itself, which has important implications for how we then measure and study it. Dr. Kaeberlein shares his thoughts on this as well as the latest on longevity interventions such as rapamycin, metformin, intermittent fasting, and caloric restriction. Find out why he thinks we'll always hit a wall with moving the needle on lifespan, and why healthspan is such an important target. I think you will find this conversation illuminating and useful. An additional note for any of my listeners/readers who have been tracking the various discussions around the utility of epigenetic clocks and other measures of aging: I personally very much believe in epigenetics, even as the field continues to evolve. The foundation of this traces back to my beginnings in this field, working under my mentor Richard Lord PhD, who taught me that as scientists and clinicians we have no choice but to embrace uncertainty. No laboratory tests are as precise as many of us would like to think they are - microbiome, organic acid, nutrient testing, those foundational tools of functional medicine that we are very comfortable using, included. This applies to standard labs too - I recently received a notification from one of the two biggest labs in the US stating that, due to a change in the testing instrument used, values for red cell indices (the oldest tests on the planet!) would be altered compared to prior results. As clinicians we have to grapple with uncomfortable uncertainty in medicine every single day - from that reality we still have to move forward and make the best clinical decisions we can. Epigenetic age testing is simply another tool in the mix that can add value to understanding a patient's picture, and we can use it even as we interpret it with a similar acknowledgement of uncertainty. If you would like to add your thoughts to this discussion, please share below. - DrKF Check out the show notes at https://www.drkarafitzgerald.com/fxmed-podcast/ for the full list of links and resources.
