Filter by:Sleep disordered breathing (SDB) insidiously worsens metabolic function, heightens insulin resistance (IR), and in pregnancy is thought to precipitate gestational diabetes, preterm birth, growth restriction, gestational hypertension, and preeclampsia. Despite the fact that sleep disturbances are common during pregnancy, SDB remains under-recognized, under-diagnosed, and poorly understood, particularly in pregnancies affected by obesity. Sixty percent of pregnancies are now affected by obesity, yet the relationship between SDB, patterns of glycemia, and insulin resistance (IR) in obese pregnant women is a neglected area with major therapeutic implications to improve maternal and infant health. Using a prospective design in which diet and gestational age are highly controlled, the investigators propose to measure SDB (apneas/hypopneas) in obese pregnant women using an ambulatory sleep monitoring system. In parallel, robust patterns of glycemia will be measured with a continuous glucose monitoring system (CGMS), followed by a 75g oral glucose tolerance test to measure insulin action. The investigators global hypothesis is that worse SDB in part accounts for higher 24-hour patterns of glycemia in obese normal glucose tolerant (NGT) pregnant women in their 3rd trimester. The Investigators will test the hypothesis that: 1) In obese NGT pregnant women at 32-34 weeks gestation on a controlled eucaloric diet, higher apnea hypopnea index (AHI) will be positively associated with 24-hour glycemia measured by a CGMS and that, 2) Higher AHI in obese NGT pregnant women at 32-34 weeks gestation on a eucaloric controlled diet will be associated with higher insulin resistance measured by a 75g oral glucose tolerance test (Matsuda Model). Early identification and treatment has the potential to decrease long-term maternal cardiovascular morbidity and mortality.
This study will evaluate if the timing of oxytocin administration in cesarean deliveries will affect the amount of maternal blood loss. Half of participants will receive oxytocin after delivery of the fetal anterior shoulder and the other half will receive oxytocin after delivery of the placenta. We hypothesize that administering oxytocin after delivery of the shoulder, will result in less overall maternal blood loss.
Our hypothesis is that aggressive preconception weight loss in obese women will improve the metabolic health of the mother and the intrauterine environment. An optimized developmental environment will normalize fetal growth and improve clinical fetal and infant outcomes, and theoretically reduce future susceptibility to obesity and cardiometabolic disease.
To assess health and lifestyle behavior of pregnant women in Baton Rouge including women receiving traditional obstetrical prenatal care and delivering in a hospital and those receiving prenatal care from a midwife and delivering at the birth center.
The purpose of the study is to compare 3 different diets in pregnancy, equal in calories, and fats, different in refined grains compared to whole grains as a source of carbohydrates, and in calories from carbohydrate, compared to protein as a source of calories.The hypothesis is that there will be differences in the specified outcomes because the proportions of macronutrients are significant. The primary objective is to detect differences in weight gain.
The trial aims to determine whether or not MiQuit (text-message support programme) is effective when offered in addition to standard behavioural support for smoking cessation in pregnancy.
Purpose of this study is to learn more about how nutritional advice given during pregnancy affects a mother's food choices and her baby's growth.
Investigators will assess the feasibility of implementing a randomized control trial of a behavioral intervention that uses smartwatch technology to monitor smoking behavior with texts aimed at reducing smoking in pregnant women who smoke. Investigators will compare the cessation rate of pregnant women who receive usual care through programs aimed at reducing smoking with pregnant women who receive usual care and are using the SmokeBeat app with a smartwatch.
This study will evaluate the potential impact of a brief musical intervention, the Lullaby Project, in a sample of pregnant women. The study aims are: 1. To determine the potential effect of the Lullaby Project on maternal-fetal attachment. 2. To evaluate the potential impact of the Lullaby Project on maternal mental health. 3. To characterize the potential impact of the Lullaby Project on perceived maternal stress.
Pregnant women have increased morbidity and mortality due to infection with influenza. Changes in T cell function have been proposed as possible mechanisms for this finding. We believe that pregnancy induced changes in NK cell phenotype and function also impact influenza immunity. This study will compare the immune response of pregnant women and controls to TIV influenza vaccination as a surrogate for infection. In addition pregnant women with flu like illness will be enrolled to evaluate changes in immune response following influenza infection as compared to vaccination.
