Send us Fan MailWe often assume confusion after surgery is temporary. But what if those few days of delirium are actually a major turning point in the aging brain? New research from Harvard and Hebrew SeniorLife suggests postoperative delirium may be the strongest predictor of long-term cognitive decline - and what we're learning could fundamentally change how we think about dementia and healthy aging.Each year, millions of older adults undergo surgery successfully, only to experience episodes of confusion, disorientation, memory impairment, or altered awareness in the days that follow. For decades, many clinicians viewed postoperative delirium as a temporary complication that resolved once patients left the hospital.But emerging research suggests a much more profound story.Our guest today is Dr. Tammy Hshieh, MD, MPH, is physician-scientist, geriatrician, and internationally recognized expert on delirium, cognitive impairment, and healthy aging. Dr. Hshieh serves as Assistant Scientist at the Hinda and Arthur Marcus Institute for Aging Research at Hebrew SeniorLife ( https://www.marcusinstituteforaging.org/who-we-are/profiles/tammy-hshieh-md-mph ), Assistant Professor of Medicine at Harvard Medical School ( https://connects.catalyst.harvard.edu/Profiles/display/Person/33333 ), and Associate Physician at Brigham and Women's Hospital ( https://physiciandirectory.brighamandwomens.org/Details/12170 ).After earning her undergraduate degree in Biochemistry from Harvard University and her MD from Brown University's Alpert Medical School, Dr. Hshieh completed residency training in Internal Medicine at Beth Israel Deaconess Medical Center, a fellowship in Geriatric Medicine through Harvard Medical School, and earned a Master of Public Health from the Harvard T.H. Chan School of Public Health.Dr. Hshieh's research focuses on understanding, preventing, and treating delirium and cognitive decline in older adults - conditions that carry enormous consequences for independence, quality of life, and healthcare systems worldwide.In groundbreaking work recently published in JAMA Internal Medicine, Dr. Hshieh and colleagues demonstrated that postoperative delirium remains the strongest predictor of long-term cognitive decline, even after accounting for rehospitalizations and other markers of illness and frailty. Their findings suggest that delirium may represent far more than a transient hospital complication - it may be a critical turning point in the trajectory of brain aging itself.Clinically, Dr. Hshieh co-manages older surgical patients at Brigham and Women's Hospital in one of the nation's most innovative geriatric-surgical care programs and leads the Older Adult Hematologic Malignancy Clinic at Dana-Farber Cancer Institute ( https://www.dana-farber.org/find-a-doctor/tammy-t-hshieh ), where she works to improve outcomes for older adults facing cancer treatment.Today we'll discuss delirium, dementia, cognitive resilience, surgical risk, brain aging, and what patients, families, and healthcare systems can do to better protect the aging brain.#Delirium #Dementia #BrainHealth #HealthyAging #CognitiveDecline #Alzheimers #HarvardMedicine #Geriatrics #Longevity #Surgery #PostoperativeDelirium #AgingResearch #Neuroscience #Healthcare #Medicine #BrainAging #CognitiveHealth #Prevention #Podcast #ProgressPotentialPossibilitiesSupport the show

Send us Fan MailFor decades, scientists have searched for better cancer drugs. But what if the biggest challenge isn't discovering the drug - it's getting it to the tumor?

Send us Fan MailFor decades, medicine has recognized that pregnancy and menopause transform nearly every system in the body. Yet only recently have researchers begun asking a simple question: what happens to chronic skin diseases like eczema and psoriasis during these major biological transitions? The answers may reveal one of the biggest blind spots in modern medicine.Dr. Doral Fredericks, PharmD, MBA is Vice President and Head of Global Medical Affairs and Outcomes Research at Organon ( https://www.organon.com/ ), a global healthcare company focused on improving women's health throughout every stage of life.With nearly three decades of experience spanning clinical pharmacy, pharmaceutical development, medical affairs, and healthcare strategy, Dr. Fredericks has held senior leadership roles across some of the world's leading healthcare organizations, including Organon, Dermavant Sciences, ACADIA Pharmaceuticals, Bausch + Lomb, Novartis, AstraZeneca, and Kaiser Permanente.Throughout her career, Dr. Fredericks has led global medical affairs organizations, overseen clinical development programs, real-world evidence generation, physician education initiatives, and outcomes research efforts across multiple therapeutic areas. Her work has focused on translating scientific innovation into meaningful improvements in patient care while helping healthcare systems better understand the unique needs of diverse patient populations.Today, Dr. Fredericks is helping drive a growing conversation around female dermatology - a field examining how major biological transitions such as pregnancy, postpartum recovery, perimenopause, and menopause can profoundly influence chronic skin diseases including eczema, psoriasis, and other inflammatory conditions.On this episode, we'll explore why women's skin health remains an underrecognized area of medicine, how hormonal and immune changes across a woman's lifespan affect dermatologic disease, and what the future of personalized care may look like as researchers begin paying closer attention to the unique biology of female patients.#WomensHealth #Dermatology #Menopause #Psoriasis #Eczema #SkinHealth #Healthcare #PrecisionMedicine #AutoimmuneDisease #Hormones #Postpartum #PregnancyHealth #MedicalResearch #Inflammation #Medicine #Organon #Dermatologist #HealthyAging #Longevity #HealthcareInnovation #SciencePodcast #MedicalScience #FutureOfMedicine #SkinDisease #ProgressPotentialPossibilitiesSupport the show

Send us Fan MailHe spent fifty-five years searching for answers. Dozens of doctors. Hundreds of tests. Twelve different diagnoses. And what he discovered wasn't just a problem with medicine - it was a problem with the system itself.Haresh Patel ( https://hareshpatel.ai/ ) is an entrepreneur, engineer, Founder and CEO of Sanare Health AI ( https://sanarehealth.ai/ ), and author of the memoir The Ghost in My Body: What Twelve Doctors Couldn't Find ( https://www.amazon.com/Ghost-My-Body-Doctors-Couldnt-ebook/dp/B0GL561XNC ).After immigrating from India and earning an electrical engineering degree from the University of Notre Dame, Haresh built a distinguished career in Silicon Valley, ultimately founding Mercatus, a private-markets data platform that grew to manage more than $1.5 trillion in assets before being acquired by State Street in 2021.But behind that business success was a deeply personal story. For more than 55 years, Haresh lived with unexplained symptoms, navigating a maze of specialists, tests, and conflicting diagnoses without ever receiving a clear answer. Rather than accepting the limitations of the system, he applied the same systems-thinking and pattern-recognition skills that made him successful in technology and finance to his own health journey.That experience led Haresh to a provocative conclusion: many patients don't suffer from a lack of doctors - they suffer from a lack of synthesis. Modern medicine excels at specialization, but often struggles to connect information across disciplines, timelines, and life experiences.Today, Haresh is the founder of Sanare Health AI, an AI-powered diagnostic intelligence platform designed to help patients with complex, chronic, and undiagnosed conditions uncover patterns hidden within fragmented medical data. His mission is to give physicians a more complete picture of the patient, empower individuals to own their health stories, and help solve one of healthcare's most overlooked challenges: the millions of people still searching for answers.We discuss diagnostic failure, AI in medicine, data sovereignty, root-cause healthcare, and what happens when a patient spends a lifetime becoming the expert on his own condition.#HareshPatel #TheGhostInMyBody #SanareHealth #ArtificialIntelligence #AIHealthcare #RareDisease #UndiagnosedDisease #DiagnosticOdyssey #PrecisionMedicine #RootCauseMedicine #HealthcareInnovation #FutureOfMedicine #MedicalAI #HealthTech #ChronicIllness #PatientAdvocacy #Longevity #MedicalDiagnostics #ComplexPatients #ProgressPotentialPossibilitiesSupport the show

Send us Fan MailBefore your heart, brain, or lungs fully developed, one remarkable temporary organ was making decisions that may influence your health for decades. Dr. Perrie O'Tierney-Ginn ( https://www.placentascience.com/ ) explains why the placenta could be the most important organ you've never thought about.Dr. Perrie O'Tierney-Ginn, Ph.D. is Executive Director of the Woman, Mother & Baby Research Institute at Tufts Medical Center ( https://www.tuftsmedicine.org/research-clinical-trials/research-institutes-research-specialty/woman-mother-baby-research-institute ) and a Research Associate Professor in both Obstetrics & Gynecology at Tufts University School of Medicine ( https://www.tuftsmedicine.org/research-clinical-trials/research-institutes-research-specialty/woman-mother-baby-research-institute/laboratories/otierney-ginn-laboratory ) and the Friedman School of Nutrition Science and Policy ( https://nutrition.tufts.edu/academics/faculty/perrie-otierney-ginn ).A self-described "Perinatal Ecologist," Dr. O'Tierney-Ginn studies one of the most remarkable - and often overlooked - organs in human biology: the placenta. Her research explores how a mother's nutritional status, metabolism, and environment shape placental function, influence fetal growth, and ultimately affect lifelong health outcomes.Supported by the Eunice Kennedy Shriver National Institute of Child Health and Human Development, Dr. O'Tierney-Ginn's work focuses on understanding how nutrients are transported from mother to baby, how maternal obesity and metabolic health alter fetal development, and how the placenta acts as a sophisticated biological sensor that helps determine the earliest foundations of human health.With a Ph.D. in Cell Biology and Anatomy from Queen's University and leadership roles at Case Western Reserve University and Tufts Medical Center, Dr. O'Tierney-Ginn is helping redefine our understanding of pregnancy - not as a nine-month event, but as one of the most important developmental windows influencing health across the entire lifespan.#Placenta #Pregnancy #MaternalHealth #WomensHealth #DevelopmentalBiology #Longevity #Metabolism #Obesity #Diabetes #Nutrition #PrecisionMedicine #Epigenetics #Microbiome #SciencePodcast #Medicine #FetalDevelopment #TuftsMedicine #PublicHealth #PreventiveMedicine #FutureOfHealthSupport the show
