Early Detection of Gestational Diabetes Mellitus in Pregnancy

The purpose of this study is to develop an implementation protocol and test the feasibility and acceptability of a first trimester screening protocol for the early detection of gestational diabetes mellitus (GDM).

Postpartum Continuous Glucose Monitoring for Type 2 Diabetes Mellitus Risk Evaluation in Patients With Gestational Diabetes Mellitus: POSTPOD Trial

This is a pilot study designed to evaluate the effectiveness of continuous glucose monitoring (CGM) within hours of delivery to predict long-term risk of Type 2 Diabetes Mellitus in patients diagnosed with gestational diabetes. Participants will be provided a CGM within 2 hours after delivery and wear the device for 24 hours. Participants will be instructed to peel off the device after 24 hours. Participants will also be asked to complete two surveys regarding their experience at 1-3 months postpartum and 12-14 months postpartum.

Effects of a Non-nutritive Sweetener Reduction Intervention in Pregnancy and Lactation on Maternal and Infant Outcomes

The effects of consuming non-nutritive sweeteners (NNS) during pregnancy and lactation on infant obesity and cardiometabolic disease risk are not well understood. In this project, pregnant women who frequently consume NNS will be randomly assigned to an NNS-restriction intervention (NNS restriction during pregnancy and lactation or during lactation only) or a control group (no NNS restriction) to determine whether NNS consumption during pregnancy and/or lactation affects infant body composition, maternal blood sugar during pregnancy, and the infants' gut microbiome and metabolome. The results of this study have the potential to shape recommendations around NNS consumption during pregnancy and lactation, thereby potentially improving maternal and infant metabolic health and reducing the global burden of obesity and cardiometabolic disease.

Physical Acvitiy in Pregnancy

The goal of this observational study is to learn how a physically active lifestyle during pregnancy affects placental development and function. The main question it aims to answer is: Does regular physical activity during pregnancy improve placental function and support healthy fetal growth? Pregnant participants will provide biological samples and health information during pregnancy and at delivery. The study will use these samples to examine how activity levels relate to placental energy production and overall health.

New Markers of Glycation to Predict Gestational Diabetes Mellitus and Macrosomia.

Gestational diabetes mellitus (GDM) increases the risk of macrosomia and other adverse pregnancy outcomes. Screening strategies are debated: universal vs. selective, and macrosomia may begin before the time of screening, suggesting that glycation markers may have an interest. The objective of this trail is to compare novel markers: skin autofluorescence and glycated albumin, to HbA1c (reference) as predictors of GDM, macrosomia and other adverse outcomes, in pregnant women.

Effectiveness Study of a Lifestyle Intervention Versus Metformin in Mothers With Recent Gestational Diabetes

The goal of this clinical trial is to evaluate the effectiveness of a 6-month lifestyle intervention compared to Metformin in postpartum women who have delivered a singleton, live born infant within the last 12 weeks to 1 year and had a pregnancy complicated by gestational diabetes. The main question this study aims to answer is: Is a Lifestyle Intervention or Metformin more effective for weight loss in postpartum women with recent gestational diabetes? Researchers will compare a 6-month Lifestyle Intervention and Metformin to see if either intervention is more effective in achieving weight loss and improving health outcomes. Participants will: * Attend an in-person baseline visit to receive a Bluetooth-enabled scale and Fitbit, have blood drawn for testing, and have their height, weight, and blood pressure measured. Participants will also be asked to bring in their infant, and the study team will measure the infant's weight and length. * Track diet, physical activity, and weight using the Fitbit and Looseit! apps. * Attend weekly online group sessions for the first 4 weeks, then biweekly sessions. * If not meeting weight loss goals, be randomized to either Enhanced Lifestyle Intervention or Metformin arms of the study. * If randomized to Metformin, participants will attend one in-person meeting with the study provider, get blood drawn for testing, and undergo a urine pregnancy test before starting the medication. * Continue with biweekly group sessions or have regular check-in calls. * If randomized to the Enhanced Lifestyle Intervention, participants will get a free Instacart membership, a 1:1 session with the study health counselor focused on meal planning and free grocery delivery once a week for the remainder of the study. * Participants will meet every other week via Zoom with the health counselor and other participants in the enhanced lifestyle arm. * At the end of the 6 months, all participants will come for an in-person visit to get blood drawn for testing. Participants will also be asked to bring in their infant, and the study team will measure the infant's weight and length.

CGM for the Early Detection and Management of Hyperglycemia in Pregnancy

The goal of this clinical trial is to use continuous glucose monitoring (CGM) to quickly detect and manage high blood sugar in pregnant women, early in pregnancy. The main questions it aims to answer are: (1) any problems for the baby, such as being too large for their age, shoulder injuries (like broken bones), high bilirubin levels needing light treatment, low blood sugar, or needing to stay in the NICU; (2) any high blood pressure issues for the mother during pregnancy.

Intrapartum Glucose Control and Risk of Neonatal Hypoglycemia

The purpose of this study is to assess whether a liberal intrapartum glycemic target range compared to usual care standard control ranges will lead to a decrease in the rate of neonatal hypoglycemia among pregnant patients in labor with diabetes.

Relationship Between Aspirin Metabolism and Markers of Metabolic Dysfunction Among Pregnant Persons at Risk of Pre-eclampsia

This study's primary purpose is to determine the relationship between aspirin metabolism and markers of metabolic dysfunction among patients at risk for preeclampsia.

Effects of Rhythm-Based Music on Pregnancies With Gestational Diabetes

This study is for people who have gestational diabetes, a type of diabetes that happens during pregnancy. People with gestational diabetes may feel more anxious than others during pregnancy. This anxiety can affect their health and their baby's health. The goal of this study is to see if rhythm-based music can help lower anxiety and improve blood sugar and stress hormone levels. Music may be a safe and low-cost way to support emotional and physical health during pregnancy. Researchers will test two types of music activities: Listening to rhythm-based music Doing rhythm-based music and breathing exercises The study will include 180 pregnant participants. They will be randomly placed into one of three groups. Each group will be at a different hospital to prevent crossover. Two groups will receive music activities, and the third group will receive usual care. Participants will stay in the hospital for 3 days. During that time: Anxiety will be measured on day 1 and day 3 using a short questionnaire Blood sugar will be measured 3 times a day (morning, afternoon, evening) Saliva samples will be collected on day 3 to measure cortisol (a stress hormone) Researchers will also record any medications used by participants. This study may show that music helps lower anxiety and improve health for people with gestational diabetes. It may also support the use of music as a helpful, non-drug option during pregnancy.

Gestational Diabetes Monitoring and Management

The primary goal is to predict the clinical outcomes of mother and baby using blood glucose and other routinely collected clinical data in pregnancy to predict adverse outcomes at birth in women with GDM. The secondary goal is to develop models to predict optimal blood glucose testing schedules for pregnant women. Exploratory Objectives are (1) to understand patterns of dosage and / or medication choice and (2) to describe different phenotypes of gestational diabetes based on multiple data input.

First Trimester Prediction of Gestational Diabetes Mellitus by Continuous Glucose Monitoring.

Gestational diabetes mellitus (GDM) is the most common complication of pregnancy, with an incidence rate of 10-15% \[1\]. Common risk factors for GDM are increased maternal age and weight and as a consequence of women delaying childbirth and increasing incidence of obesity, there is a corresponding increase in the rate of GDM. GDM is associated with an increased risk of maternal and perinatal short and long-term complications . These include macrosomia, shoulder dystocia, neonatal hypoglycaemia, neonatal hyperbilirubinemia, and perinatal mortality. Maternal complications include higher risks of hypertensive disorders, perineal trauma, and caesarean section. Additionally, both the mothers with GDM and their infants have an increased risk of developing type 2 diabetes mellitus and cardiovascular disease later in life . Screening and diagnosis of GDM is currently based on an oral glucose tolerance (OGTT), which is carried out at 26-28 weeks' gestation. In addition, an OGTT is carried out at 11-13 weeks in women considered to be at increased risk of GDM based on their demographic characteristics and medical history. Screening and diagnosis of GDM is traditionally delayed until the late second or early third trimester of pregnancy with the rationale that the diabetogenic effects of pregnancy increase with gestation and therefore delayed testing would maximize the detection rate.

Mobile App Logging for Diabetes in Pregnancy

To determine the effect of using a mobile app versus paper logs on compliance and percentage in range blood sugars in monitoring blood sugar in pregnant women with diabetes.

MIRACLE of LIFE Study

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)?

Comparison Between Metformin and Glyburide in the Management of Gestational Diabetes

This study aims to compare the maternal, fetal, and neonatal outcomes associated with the use of metformin versus glyburide for managing gestational diabetes. The objective is to assess the safety and effectiveness profiles of both medications as potential alternatives to initiating insulin therapy.
