Dr. Robert Baron outlines major updates in type 2 diabetes care, emphasizing that blood sugar control alone does not significantly reduce cardiovascular risk, though it helps prevent microvascular complications. New guidelines now prioritize medications with proven cardiovascular and kidney benefits—GLP-1 receptor agonists and SGLT2 inhibitors—over traditional first-line therapy like metformin. Baron explains how these newer drugs not only lower blood sugar but also reduce the risk of heart attack, stroke, kidney disease, and heart failure, with added benefits such as weight loss. He also covers changes in screening, diagnosis, blood pressure goals, and individualized treatment strategies based on age, comorbidities, and patient preferences.

Sarah Banks, Ph.D. explores why Alzheimer's disease affects women differently than men, emphasizing distinct patterns in tau pathology, cognitive testing bias, and treatment response. She explains how women tend to show a rapid buildup of tau during early cognitive decline, which may contribute to their higher prevalence of Alzheimer's. Banks also highlights how common diagnostic tools may overlook symptoms in women and how approved treatments may offer less benefit for them. Her research at UC San Diego investigates key sex-based differences in risk factors, including sleep apnea, diabetes, and exercise. One study reveals that over 70% of participating women had undiagnosed sleep apnea. Another focuses on Black women, using blood biomarkers to identify overlooked risks and improve care.

UCSF researchers June Chan and Stacey Kenfield share evidence-based strategies for improving prostate cancer outcomes through exercise and diet. They highlight studies showing that physical activity—including resistance and high-intensity interval training—is linked to lower risk of prostate cancer progression and death. They discuss plant-based diets, dietary indices, and specific foods like tomatoes, fish, and nuts, along with the benefits of substituting plant oils for butter. Their analysis includes findings on racial disparities and underscores the need for inclusive research. They also describe current clinical trials exploring lifestyle tools and offer guidance on navigating diet and exercise choices during cancer survivorship.

Dr. Robert Baron reviews best practices in lipid management for preventing cardiovascular disease, with a focus on statin use. He outlines the strong evidence for statins in reducing heart attack and stroke risk by 25–33%, particularly in patients with clinical atherosclerotic disease, diabetes, or high LDL. He explains why shared decision-making is key in primary prevention, where guidelines vary and risk thresholds are debated. Baron discusses the shift to the newer PREVENT risk calculator, which offers improved accuracy and removes race as a factor. He also explains when additional lipid-lowering medications may be appropriate and clarifies the impact of risk-enhancing factors like family history, coronary artery calcium, and LP(a).

As part of the 2025 Developmental Disabilities Conference, Dr. Mary Dubon of Harvard Medical School talk about adaptive and para sports for youth with physical and developmental disabilities. Series: "Developmental Disabilities Update" [Health and Medicine] [Show ID: 40617]

Jennifer Anger, M.D., M.P.H., Ph.D. investigates interstitial cystitis (IC), also known as painful bladder syndrome, with a focus on improving care through research on sex, gender, and health disparities. Using Veterans Affairs (VA) data, Anger challenges the outdated belief that IC predominantly affects women. She explores how comorbidities such as PTSD and depression, common among veterans, influence bladder pain, and examines how factors like exercisJennifer Anger, M.D., M.P.H., Ph.D. uses VA data to study interstitial cystitis.. She examines links between bladder pain, PTSD, depression, diet, and disparities to improve care across all gender identities.e, diet, and neighborhood deprivation impact symptoms. By including both cis and trans women as well as men, Anger seeks to advance more inclusive, data-driven understanding and treatment of IC across all populations.

Dr. Steven Seyedin presents an overview of PSA recurrence and risk factors for assessment. A PSA test is a blood test used to detect prostate-specific antigen (PSA) levels in the blood, which can be elevated in cases of prostate cancer and is a common screening tool. He explains how PET, CT, and MRI work, highlighting the precision of PSA PET in detecting cancer spread by targeting PSA proteins on tumor cells. This imaging method combines PET and CT to reveal metastatic disease with greater accuracy than traditional scans. Seyedin addresses the strengths of different imaging agents, emphasizing that access, not brand, is key. He also cautions against false positives, especially in bone lesions, which can mislead diagnosis. By improving staging accuracy, PSA PET supports better treatment planning and outcomes. Ongoing studies explore its use earlier in diagnosis, potentially replacing biopsy or MRI in select cases. Series: "Prostate Cancer Patient Conference" [Health and Medicine] [Show ID: 40805]

Gladys (Sandy) Ramos, M.D. outlines the comprehensive maternal care services at UC San Diego, emphasizing clinical excellence, innovation, and community impact. She highlights programs in diabetes and pregnancy, high-risk obstetrics, postpartum and HIV care, and maternal mental health. Ramos describes cutting-edge capabilities in fetal and placental imaging, including expertise in placenta accreta and genetic counseling. A fetal surgery program is launching soon, expanding access to specialized care and research. The department’s patient population closely reflects San Diego County’s demographics, which informs both clinical care and research priorities. Ramos also details a collaborative structure with multidisciplinary conferences and welcomes partnerships in research related to maternal, placental, and fetal health.

UCLA’s Avishek Adhikari, PhD, presents new research on the role of GABAergic neurons in the brain’s periaqueductal gray (PAG) region. Previously studied for their involvement in fear and defensive behaviors, these neurons were found to promote food-seeking behavior when activated—even in fully fed mice. Using calcium imaging and optogenetics, Adhikari’s team discovered that these neurons are active during food approach but suppressed during eating. The effect is stronger for high-value foods like chocolate or crickets and depends on the mouse’s prior experience with that food. A key finding is that these neurons influence behavior through a specific projection to the zona incerta, a subthalamic region. Rather than signaling hunger, this pathway appears to drive food seeking based on reward value, highlighting a new motivational circuit in the brain.

Sheng Zhong, Ph.D. pioneers technologies that advance women’s reproductive health. Zhong develops a minimally invasive method to analyze extracellular RNA secreted by embryos during IVF. By sequencing tiny samples of spent culture media, they generate comprehensive RNA profiles and use machine learning to identify biomarkers that predict embryo quality with accuracy comparable to traditional imaging. This breakthrough offers a gentler, data-driven alternative for assessing embryo viability, with the potential to improve live birth rates and support families navigating infertility. Zhong’s research highlights the power of molecular innovation to transform fertility care and address critical challenges in women’s health.
