Social isolation may influence how the body recovers from pelvic floor injury after childbirth. Lindsay Burnett, M.D., Ph.D., assistant professor and physician-scientist at UC San Diego, studies factors during pregnancy and postpartum that may affect pelvic floor muscle recovery, including medications, diet, exercise and social interaction. Her research grew from clinical observations connecting patients’ perceptions of traumatic births with physical outcomes such as fecal incontinence. In a preclinical model, social support was associated with improved pelvic floor muscle regeneration and distinct metabolic changes. Burnett is investigating metabolites involved in wound healing and skeletal muscle regeneration, along with possible connections between social interaction, the gut microbiome and systemic metabolism. The research offers a biological perspective on why emotional and social support may matter during postpartum recovery. Series: "Motherhood Channel" [Health and Medicine] [Show ID: 41640]

Mechanical forces may help the body coordinate pregnancy and labor. Yunxiao Zhang, Ph.D., of Scripps Research Institute, examines how PIEZO1 and PIEZO2, proteins that open in response to stretch, contribute to uterine contractions and the timing of birth. Zhang finds PIEZO1 in uterine smooth muscle and PIEZO2 in sensory nerve fibers around the cervix. In mouse models, removing both channels weakens labor contractions, delays the start of delivery and increases the time between pups. The findings suggest that PIEZO1 helps prepare uterine muscle for stronger contractions, while PIEZO2 helps sensory nerves detect cervical stretch. Zhang also discusses how fats in cell membranes may change PIEZO1 sensitivity and why uterine cells and sensory nerves have connected roles. This research offers a new way to study how physical forces help regulate labor. Series: "Motherhood Channel" [Health and Medicine] [Show ID: 41642]

Menopause care is changing as more patients seek evidence-based guidance for symptoms, prevention, and long-term health. Kathryn Macaulay, M.D., M.S.C.P., F.A.C.O.G., UC San Diego Health, and Rajita Patil, M.D., M.S.C.P., F.A.C.O.G., UCLA Health, explain why many people still struggle to find trained care, even as menopause affects sleep, mood, work, genitourinary health, and cardiometabolic risk. They connect hormone therapy history with today’s demand for reliable, individualized options, including non-hormonal approaches, and outline the UC Menopause Collaborative’s work to expand training, standardize work flows, support flexible care models, and build research-ready data across UC health centers.

Cardiovascular disease is a major threat to maternal health during pregnancy and the peripartum period, particularly for women with preexisting heart conditions. A UC San Diego cardiologist describes the development of a multidisciplinary cardio-obstetrics initiative designed to coordinate care for patients with congenital heart disease, heart failure, arrhythmias and coronary artery disease. The program brings cardiology and maternal-fetal medicine together with other specialties to establish consistent protocols, improve maternal and fetal outcomes, advance research and train future clinicians. As more people born with congenital heart disease survive into adulthood and consider pregnancy, the need for this specialized care continues to grow. Longitudinal surveillance is also helping researchers study outcomes and identify opportunities for better monitoring. Coordinated cardio-obstetrics care can help manage complex cardiovascular risks throughout pregnancy and delivery. Series: "Motherhood Channel" [Health and Medicine] [Show ID: 41641]

AI-powered cell imaging may help researchers identify biological differences that are difficult or impossible to see by eye. Yu-Hwa Lo, Ph.D., and Louise Laurent, M.D., Ph.D., describe a system that combines high-speed imaging, cell sorting, microfluidics, and artificial intelligence. The technology creates label-free images of cells, uses AI to classify them, and can isolate selected cells for deeper molecular analysis. Laurent explains how the team is applying the system to human trophoblast stem cells, which give rise to specialized placental cells involved in nutrient transport, hormone production, blood vessel remodeling, and immune regulation. Lo describes how AI can distinguish cell populations and identify features that may not be apparent to human observers. The researchers ultimately hope to connect imaging features with gene expression, proteins, and metabolism, allowing cell characteristics and behavior to be predicted from images alone.

Continuous glucose monitoring and wearable data are changing how researchers study pregnancy and women’s health. Gladys (Sandy) Ramos, M.D., explains why glucose control is difficult during pregnancy and how CGM can reveal patterns that finger-stick testing may miss. She also describes research on CGM use in type 2 and gestational diabetes, labor, and behavior change. Ben Smarr, Ph.D., shows how wearable data can track changes in temperature, heart rate, activity, respiration, menstrual cycles, pregnancy, and aging. Together, the speakers discuss personalized care, participant engagement, patient-driven innovation, and access to these tools. The goal is to learn from continuous data while recognizing limits in evidence, interpretation, and equity. Series: "Motherhood Channel" [Health and Medicine] [Show ID: 41636]

Alzheimer’s disease can begin developing years before memory and thinking problems become noticeable. Iris Broce-Diaz, Ph.D., of UC San Diego is developing accessible, noninvasive, and cost-effective tools to help primary care physicians and neurologists identify people at higher risk earlier. Her models combine information from cognitive assessments, brain imaging, genetics, and PET scans to estimate the likelihood that mild cognitive impairment will progress within five years. Combining multiple measures improves the models’ ability to separate higher- and lower-risk patients. Broce-Diaz also plans to add women-specific factors, including menopause history, hormone therapy, reproductive history, endocrine markers, and symptoms. The goal is to support better referrals, guide monitoring, and help eligible patients consider treatment sooner. Earlier risk assessment could also strengthen clinical trials and make dementia care more useful across different health systems. Series: "Motherhood Channel" [Health and Medicine] [Show ID: 41632]

Men with non-obstructive azoospermia may undergo microscopic testicular sperm extraction, or mTESE, without knowing whether sperm will be found. Kun Tan, Ph.D., of UC San Diego explains how molecular semen analysis could provide a noninvasive way to predict the procedure’s outcome. The assay uses stage-specific germ cell markers identified through single-cell RNA sequencing, then measures those markers in semen with qPCR. Because semen contains germ cells from different stages of sperm development, their molecular signals may reflect what is happening inside the testes. Tan shows how the assay predicts whether sperm retrieval was successful and can identify where sperm development may be blocked. The research could help couples planning IVF or ICSI avoid unnecessary surgery, reduce financial and emotional burdens, and receive more detailed information about male infertility before treatment.

Menopause can affect sexual health in ways that are common, frustrating, and often overlooked. Kathryn Macaulay, M.D., Director, UC San Diego Menopause Health Program, explains how hormonal changes during perimenopause and menopause contribute to vaginal dryness, pain with intercourse, and low libido. Macaulay also outlines why these symptoms can have more than one cause, including physical changes, life stressors, relationship factors, and other health conditions. This discussion helps clarify that sexual symptoms during menopause are common and treatable, and it points toward more informed conversations with a health care provider.

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.
