Vaginal microbiome research may offer new ways to understand infections, fertility, preterm birth and other areas of women’s health. Pita Navarro, co-founder and chief scientific officer of Evvy, joins Cynthia Gyamfi-Bannerman, M.D., M.S., of UC San Diego Health, to explain how patient-contributed samples and health information can support research and product development. Navarro describes Evvy’s direct-to-consumer testing model, its work to build a large metagenomic data set and the importance of distinguishing established findings from emerging evidence. She also discusses clinical validation, patient trust, academic partnerships and the challenges of bringing scientific discoveries into everyday care. Their conversation shows why successful health startups need more than promising science: they must solve meaningful problems, fit real-world workflows and stay close to the patients they aim to serve.

Gladys (Sandy) Ramos, M.D., is a UC San Diego Health perinatologist and professor who cares for patients with complex pregnancies, including those affected by diabetes. She explains how immigrating from Peru, learning from her grandmother and wanting to serve Spanish-speaking communities shaped her work. Ramos also describes feeling out of place in college and not getting into medical school on her first attempt. Research, mentors, supportive peers and a UC Irvine medical school preparation program helped her strengthen her skills and confidence. Today, she uses her bilingual skills and cultural knowledge to build trust, discuss nutrition and health beliefs, and help patients work toward safe pregnancies and healthy babies. Her experience also shapes the guidance she gives students pursuing medicine.

More than 7 million Americans are living with Alzheimer's, according to the Alzheimer's Association. UC Davis researcher Alyssa Weakley is working on I-Care, a new technology that's helping Alzheimer's patients live longer in their own homes.

At UC Davis, our researchers are working to better understand the causes of dementia, including Alzheimer’s, its most common form, while advancing understanding and improving care for those affected. Through innovative studies, we’re paving the way for new treatments and strategies to slow, prevent and ultimately transform how we approach these complex neurological conditions.

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.

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.
