Pregnancy Clinical Trials

This will be a randomized clinical trial. Enrolled subjects will be randomized (1:1) into two study arms to receive either daily (Group 1) or alternate day (Group 2) supplementation with one oral pill containing ferrous sulfate with an equivalent elemental iron dose of 65 mg per pill. Read Less

Maternal Fetal Monitoring devices assist the health care professional in acquiring, monitoring, and storing fetal and maternal physiologic data which supports the decision making for pregnant women and the overall fetal health status during pregnancy and delivery. This study aims to support a new maternal fetal monitoring device with clinical data to demonstrate the equivalent performance against the currently marketed Corometrics 259cx. The fetal heart rate and will be collected during antenatal monitoring using standard of care Doppler ultrasound. Read Less

The focus of this research is to create a repository of ultrasonographic images and their corresponding medical data from pregnant women (the mothers of the fetuses that are imaged), focusing on fetal anomalies. These women will visit the obstetrical clinics at Regional One Health and the Le Bonheur Fetal Center. Read Less

The purpose of this investigator-initiated prospective observational cohort study is to establish the new UCLA Perinatal Biospecimen Repository (Perinatal Repository) for collection, storage, and distribution of the human data and biospecimens of the participants with perinatal pathology. The secure and shared high-quality resource of clinical data and biological specimens (Repository Materials), across pregnancy pathology related to research protocols at the Afshar's Lab will be created. Core variables of interest include clinical characteristics and relevant biological samples. Intention to collect perinatal data is aiding the efficiency and effectiveness of de-identified biorepository for pregnancy-at-risk outcome research. The primary aims of the project are: * To design the Case Report Forms (CRFs) for the clinical and biospecimen data. * To create and update the project-specific policies, agreements, and Standard Operating Procedures (SOPs). * To develop the data management system to assure personal health information de-identification, data integrity, participants welfare, and protocol compliance. * To develop and implement a quality management system for the Repository. * To collect and record in the Repository protocol-related clinical information. * To organize a consistent system to bank high-quality biospecimens while protecting participant-donor safety and privacy. * To establish the policies and procedures for Repository Materials dissemination and research collaboration. * To analyze the scientific results of the Repository creation. The secondary aim of the study is to provide a mechanism to store and share for research purposes the de-identified biospecimen and information about participants at risk for adverse pregnancy outcomes.

The purpose of this interventional trial is to test the efficacy of the remote delivery of the StEP:Prenatal intervention compared to standard prenatal care in pregnant individuals planning to receive prenatal and pediatric care at Bellevue Hospital. The primary aims are to determine the efficacy of the remotely delivered StEP:Prenatal intervention on diet, lifestyle behaviors, social determinants of health (SDoH), and pregnancy outcomes.

The United States is in the midst of a maternal mortality and morbidity crisis, with more than half of maternal deaths occurring within the first postpartum year. Patients with hypertensive disorders of pregnancy (HDP) and diabetes have been found to be particularly high-risk, as they have a significantly increased risk for the development of cardiovascular disease in the long-term postpartum period. Traditionally, postpartum care has consisted of a single office visit at six weeks postpartum. Recent research has suggested that postpartum care should be an ongoing process, tailored to each woman's specifics needs. The purpose of this research study is to evaluate the effectiveness of obstetric care providers as primary care providers for patients at increased risk of maternal morbidity and mortality in the full first postpartum year.

The PLANET Study aims to determine the impact of microplastics on intestinal inflammation and gut microbiome in order to understand the role of this pollutant on the risk of developing inflammatory bowel disease (IBD) as well as other diseases. With this information, the researchers hope to characterize better the role of environmental pollutants on IBD and develop novel strategies towards prevention. Read Less

This study plans to learn more about how an omega-3 fatty acid supplement effects triglyceride levels in pregnancy. Triglycerides are a type of fat found in your blood. Your body converts extra calories into triglycerides to be stored and used later for energy. It is normal for triglyceride levels to go up during pregnancy however some women have levels that are \~30-40% higher than normal when they reach their third trimester of pregnancy. Having high triglycerides in pregnancy may be related to an increased chance of having a baby that is large for their age. The goal of this study is to determine if taking an omega-3 fatty acid supplement can slow the rise in triglyceride levels later in pregnancy. Read Less

This study plans to learn more about how triglyceride levels in pregnancy affect newborn fat mass. Obesity in pregnancy, in the absence of gestational diabetes, is now the most common cause of large-for-gestational-age infants and increased newborn fat mass. Previous data supports the idea that maternal triglycerides, not glucose, are the strongest predictor of both total newborn fat mass and liver fat. In this study, mothers will monitor triglyceride and glucose levels at specific points in pregnancy using point-of-care meters at home. Two weeks after birth, infants will have total fat measured by air-displacement plethysmography (PEAPOD) and liver fat measures by Magnetic Resonance Spectroscopy (MRS). The central hypothesis is that in obesity, fasting triglycerides and postprandial triglycerides will predict newborn fat mass in a free-living environment. Read Less

The overall objective of this proposal is to conduct a longitudinal prospective study of overweight/obese (OW/OB) pregnant women and their offspring to determine which prenatal exercise mode will have the greatest impact on maternal and infant cardiometabolic health. This information may lead to clinical practice recommendations that improve childhood health. This randomized controlled trial will recruit 284 OW/OB pregnant women randomized to an exercise intervention (aerobic (AE), resistance (RE), or aerobic+resistance exercise (AERE)) or to no exercise; their infants will be measured at 1, 6, and 12 months of age. This design will test our central hypothesis that AERE and RE training during pregnancy will improve maternal and offspring cardiometabolic outcomes to a greater extent than AE alone. This hypothesis will be tested with two specific aims: Aim 1. Determine the influence of different exercise modes during OW/OB pregnancy on infant cardiometabolic health and growth trajectories. Hypothesis: AE, RE, and AERE by OW/OB pregnant women will improve offspring neuromotor and cardiometabolic measures at 1, 6, and 12 months postpartum (e.g. decreased %body fat, BMI z-score, heart rate \[HR\], non-HDL, and C-Reactive Protein (CRP); increased insulin sensitivity) compared to infants of OW/OB pregnant women that do not exercise; AERE and RE will have the greatest impact on improving infant measures. Aim 2. Determine the most effective exercise mode in OW/OB pregnancy on improving maternal cardiometabolic health outcomes. Hypothesis: AE, RE, and AERE by OW/OB pregnant women will improve both maternal cardiometabolic health measures (e.g. decreased BMI z-score, non-HDL, % body fat, HR, weight gain) across pregnancy (16-36 weeks' gestation) and overall pregnancy outcomes (e.g. lower incidence of gestational diabetes, pre-eclampsia, hypertension during gestation) compared to OW/OB pregnant women that do not exercise; AERE and RE will have the greatest impact on improving maternal health measures, with the AERE group having the highest compliance. The proposed study will be the first to provide an understanding of the influence of maternal exercise modes on the cardiometabolic health and growth trajectories of offspring who are at increased risk due to maternal OW/OB. This work will have a significant impact on reducing the cycle of OB, potentially providing the earliest and most efficacious intervention to decrease or prevent OB in the next generation. Read Less
