The purpose of this study is to see if using a handheld ultrasound to measure a baby?s growth is the same as using a measuring tape to measure a mother?s fundal height. A woman?s fundal height is measured from the top of her uterus (where the baby is growing) to the area below her belly button where the pubic bone begins. Both of these methods are used a lot to measure how babies are growing but doctors would like to know if both of the ways come up with the same results. The handheld ultrasound device that is used in this study has been approved for use by the United States Food and Drug Administration (FDA).
The purpose of this study is to compare body fat distribution in neonates exposed to antiretroviral (ARV) therapy for the prevention of maternal to child transmission (MTCT) of HIV versus ARV naive neonates born at a similar gestational age to HIV-negative women. As a secondary analysis, we will examine the differences in body fat distribution among ARV-exposed neonates comparing PI-exposed versus non-PI exposed.
This study will look at abnormal blood circulation changes especially in the arteries supplying blood to the uterus (where the baby develops) using Doppler ultrasound. The research team will perform Doppler ultrasound scans at an early pregnancy scan and during the fetal anatomy scan to understand blood flow changes when subjects are lying on their back versus when they are tilted to their left and also when they bear down for 10 seconds.
The purpose of this study is to evaluate whether the AmniSure ROM (Rupture of [fetal] Membrane) test read by personnel in the subject?s room gives the same result as the AmniSure ROM test read in a laboratory. Researchers will then look to see how both results compare to the results of three standard test methods to detect ruptured (broken) fetal membranes (rupture of the sac where the fetus develops). These standard tests are called nitrazine, ferning, and pooling.
The purpose of this study is to study cells that are found in the cord blood of pregnant women to see if they might be helpful in treating certain types of infections. This type of research is still in the very early stage, so we will do this by taking some of the special cells found in cord blood and injecting them into mice and studying them.
This is a multicenter, observational study.
This research study will test whether the methods being developed for the detection of fetal abnormality from samples of maternal blood can be used in the laboratory and employed in clinical practice
Norvartis Vaccines and Diagnostics (NVD) is studying a vaccine for the prevention of Group B streptococcus (GBS) disease in babies. This is a common disease passed along to baby during birth, and that the purpose of the vaccine is to prevent this from happening, keeping baby from getting a GBS infection. This study is being conducted to learn more about the safety and immune response (how the vaccine works) of the vaccine in pregnant women and their babies.
This study will be looking to determine if specific clinical signs found in pregnant women (skin tags and darkended areas of skin) may be associated with a greater risk of a pregnant woman developing gestational diabetes and preeclampsia.
