Menopause symptoms can affect sleep, mood, and everyday quality of life in ways that are easy to dismiss but hard to ignore. Kathryn Macaulay, M.D., Director, UC San Diego Menopause Health Program, explains what menopause is, when hormone therapy is considered, and why treatment decisions depend on symptoms, health history, and individual risk. Macaulay also addresses hot flashes, night sweats, osteoporosis prevention, and the factors that shape whether hormone therapy is a good option. She helps clarify why menopause care is not one size fits all and points toward more informed conversations about symptom relief and long-term health.

Perimenopause can bring physical and emotional changes that leave many women feeling unsettled. Kathryn Macaulay, M.D., Director, UC San Diego Menopause Health Program, explains how hormonal shifts and changing menstrual cycles shape this stage of life. Macaulay examines symptoms such as irregular periods, hot flashes, and mood changes, along with broader concerns including weight, overall health, and contraception. This discussion helps clarify why symptoms vary widely, why care should be individualized, and why women do not need to panic as they move through this transition.

Academic medicine affects patient care in important ways. Julia Cormano, M.D., F.A.C.O.G., Assistant Dean for Clinical Curriculum, Associate Professor of Obstetrics, Gynecology, & Reproductive Sciences, UC San Diego, explains how medical students, resident physicians, and fellows contribute to care in a supervised teaching hospital environment. Cormano defines the role of each learner, outlines how they participate in hospitals and clinics, and shows how team-based care can bring more attention, more listening, and up-to-date medical knowledge to each patient’s case. She also explains that attending physicians oversee every decision, combining experienced judgment with the energy and perspective of learners. This work helps clarify how academic medicine supports both patient care and physician training and points toward a broader understanding of why teaching hospitals play an important role in healthcare.

Organs renew and repair themselves through stem cell systems that respond to injury, microbes, and local signals. Ophir Klein, M.D., Ph.D., of Cedars-Sinai Medical Center explains how the intestine shifts into regenerative states after injury, how long-term changes in the stem cell niche may shape later responses, and how different regions of the colon take on distinct identities. Klein also examines how bacteria help control regional gene expression in the colon, why the lining of the mouth heals faster than skin, and how oral wound healing depends on signaling between epithelial and mesenchymal cells. The program also looks at bioengineering approaches designed to control developmental signals more precisely. Together, these examples show how tissues adapt, heal, and organize themselves, pointing toward better ways to understand regeneration and improve tissue repair.

Bias in health AI can shape who gets care, how fairly risk is measured, and whether automation helps or harms patients. Karandeep Singh, M.D., M.M.S.C. explains that predictive AI can reflect historical, representation, measurement, learning, evaluation, and deployment bias, especially when models are trained on limited populations or use flawed proxies for illness and access to care. Singh also describes generative AI as a system trained first to predict text and then to follow instructions, with bias entering through training data, instruction tuning, prompts, and outside information sources. Alongside these risks, he highlights practical uses such as AI-assisted sepsis quality review and patient outreach workflows, while emphasizing governance, human oversight, disclosure, and careful measurement of whether these tools actually improve care.
