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]

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.

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.
