On this episode of Healthcare Unfiltered, Gregory Marcus, MD, MAS, cardiologist and electrophysiologist at UCSF and a leading researcher in atrial fibrillation and digital health, joins the show to explore what wearables can—and cannot—tell us about cardiovascular health.

We discuss the rapidly evolving role of devices such as the Apple Watch and Fitbit in detecting atrial fibrillation and other rhythm abnormalities, what happens when a consumer device identifies something a patient didn't know was there, and the difficult clinical questions that follow. How accurate are these alerts? What should physicians do with the enormous volume of patient-generated data? When does early detection improve outcomes, and when might it instead lead to false positives, anxiety, unnecessary testing, or overtreatment?

Wearables are becoming increasingly sophisticated. The bigger question may no longer be whether they can collect the data, but whether we know what to do with it.

A fascinating conversation about wearables, atrial fibrillation, digital health, prevention, and the future of cardiovascular medicine.

In his first interview about Ghosts in the Blood, world-renowned hematologist/oncologist and CLL researcher Jeff Sharman, MD, takes us on a fascinating journey through the history of chronic lymphocytic leukemia—from its earliest recognition in the scientific literature in 1924 to the remarkable advances that have transformed CLL treatment. Along the way, Dr. Sharman brings the history to life with stories of the patients, physicians, scientists, rivalries, setbacks, and breakthroughs that shaped the field, revealing how discoveries in CLL helped drive the broader evolution of cancer medicine from chemotherapy to monoclonal antibodies, targeted therapies, and precision medicine.

Chadi is joined by entrepreneur Dan Bickford, co-founder of Confirma and creator of the CADstream computer-aided detection software, to explore how artificial intelligence is transforming breast cancer screening with MRI. They discuss which women are most likely to benefit from breast MRI—particularly those with dense breast tissue—the evidence supporting AI-assisted interpretation as an FDA-cleared workflow tool, and how the technology complements radiologists to improve accuracy and efficiency. The conversation also examines why MRI screening is not recommended for all women with dense breasts, the practical barriers to broader adoption, and the potentially life-saving consequences of identifying the right patients for advanced imaging.

In this deeply personal episode, Allison A. Fitzgerald, MD, PhD, a pancreatic oncologist at Dana-Farber Cancer Institute, reflects on the experience of losing her mother to cancer and the story she courageously shared in ASCO Connection. She discusses what prompted her to publish such an intimate account, the unique perspective of serving as both an oncologist and a caregiver, the emotional support that sustained her, and how her family and others in her life responded to her essay. Dr. Fitzgerald also explores the often-overlooked burden placed on caregivers, why current support systems fall short, what changes are needed to better care for those caring for others, and how this life-changing experience reshaped her understanding of balance, grief, and compassion in medicine.

In this thought-provoking episode, Chadi Nabhan sits down with Thomas Seyfried, PhD, professor of biology at Boston College, to explore his controversial and unconventional views on cancer metabolism, the ketogenic diet, and the role of sugar in cancer development. Dr. Seyfried explains the science behind metabolic therapy, the origins of the glucose ketone index (GKI), why ketogenic diets have long been used to treat epilepsy, and his belief that restricting glucose and glutamine can prevent cancer growth, challenging the widely accepted view that cancer is primarily a genetic disease. They also discuss whether healthy individuals should follow a ketogenic diet, how his research is being received by the oncology community, and the evidence behind these bold claims in a candid, spirited conversation that is sure to spark debate.

Chadi speaks with Michael Karlfeldt, ND, PhD, a board-certified naturopathic doctor, integrative medicine expert, and author of Breast Cancer Breakthrough: Integrating Conventional & Natural Medicine for True Healing, about evidence-informed complementary approaches to breast cancer care. They discuss how nutritional strategies, stress management, sleep optimization, toxin reduction, and other supportive interventions can be safely integrated alongside conventional breast cancer treatments, the inspiration behind his book, and why his protocols are designed to complement—not replace—standard oncology care. The conversation also explores the challenges of limited clinical evidence for integrative medicine, how Dr. Karlfeldt evaluates available research, and what patients, caregivers, and oncology professionals should know about incorporating supportive therapies into comprehensive breast cancer treatment.
