Gestational Diabetes clinical trials at UCSD

The goal of this clinical trial is to learn if continuous glucose monitoring works better than self-monitoring of blood glucose (fingersticks) to treat type 2 diabetes in pregnancy. It will also learn about all risk factors (biologic, personal, social) for maternal and infant complications in type 2 diabetes pregnancies. The main questions it aims to answer are: 1. Does continuous glucose monitoring improve infant outcomes compared to self-monitoring of blood glucose? 2. Does continuous glucose monitoring improve maternal diabetes control and other maternal outcomes compared to self-monitoring of blood glucose? 3. What other factors increase the risk of maternal and infant complications? Participants will: 1. Use continuous glucose monitoring or self-monitoring of blood glucose to monitor blood sugar control from enrollment until delivery 2. Have blood drawn at enrollment, 24 weeks, 34 weeks and delivery to measure hemoglobin A1c levels and store blood for future analysis 3. Complete surveys about social support, environmental stressors, diabetes distress and glucose monitoring satisfaction at research visits 4. Have umbilical cord blood collected at delivery for analysis

The goal of this observational study is to develop and validate cell-free RNA-based biomarkers for predicting a variety of adverse pregnancy outcomes in a pregnant person population. The main question it aims to answer are: 1. Can cell-free RNA-based biomarkers predict which pregnant people are at greatest risk of developing adverse pregnancy outcomes (e.g., preterm birth, preeclampsia)? 2. What is the performance of such biomarkers when predicting an adverse pregnancy outcome (e.g., sensitivity, specificity, PPV, NPV, TPR)?
