Filter by:The long-term objectives of this research are to develop effective treatments to reduce unplanned pregnancy and Sexually Transmitted Infections (STIs) for a highly under-served at-risk youth population.
The aim of the present study is to prospectively evaluate whether performing an intra-uterine insemination 24 hours after the spontaneous LH peak may result in significantly higher ongoing pregnancy rates compared to 48 hours.
The purpose of this study is to compare adherence to antiretroviral therapy during pregnancy and postpartum, and to record adherence barriers and facilitators.
The aim of this study is to measure the effects of bupivacaine administered via epidural catheters on indices of motor blockade ascertained during the second stage of labor. This is a randomized, double-blind, controlled trial designed to address the primary research question: Does bupivacaine lengthen the second stage of labor? The secondary research question is: Is there other evidence of motor blockade attributable to bupivacaine during the second stage of labor? The investigators know from prior studies that the length of the second stage in nulliparous women delivered at Parkland Hospital without epidural analgesia is 28 minutes. The investigators hypothesize in this now proposed study that epidural analgesia with bupivacaine will significantly increase this baseline from 28 minutes to 37 minutes or more (a 33% increase) thus implicating motor blockade. Baseline data for the Bromage and Breen scores during the second stage as well as the uterine contractility data are not available as these indices of motor blockade have not here-to-fore been studied in this context. Currently at Parkland Hospital, 82% of nulliparous women undergoing induction of labor at term receive continuous epidural infusions with bupivacaine during the first and second stages of labor. Such women will be identified when admitted for scheduled inductions at Parkland. After informed consent is obtained standard management of labor induction will be provided. Those consented women reaching 8 cm cervical dilation will be randomized. Group I will receive bupivacaine plus fentanyl via epidural catheter during the second stage (i.e. 10 cm dilation) and Group II will receive only fentanyl infusion via epidural catheter (see study procedure below). Both the patient and the caregiver will be blinded as to whether the patient is in the bupivacaine plus fentanyl arm or the fentanyl only arm. To detect a 33% increase (from 28 minutes to 37 minutes) in the primary outcome the investigators need a total of 310 women enrolled in the study (or 155 per arm). Assuming a 30% consent rate and given that approximately 1000 women meet the inclusion criteria each year at Parkland, the investigators project that this study could be completed in 12 months.
The investigators hypothesize that home based HIV counseling and testing can increase male partner uptake of HIV testing during pregnancy. The investigators study aims through a randomized clinical trial to determine whether a home-based model (HBM) versus a partner-friendly clinic model (PFM) can increase male uptake of HIV counseling and testing during pregnancy.
This randomized, controlled trial is proposed to study the effect, in a cohort of racially and ethnically diverse group of overweight and obese pregnant women, of an Intensive Lifestyle Intervention (ILI) which utilize cognitive behavioral strategies to help participants achieve and maintain changes in dietary intake and physical activity habits compared to Usual Care (UC) on gestational weight gain (GWG), infant fatness, and mothers' post-delivery weight retention. The hypothesis is that the percent body fat at birth will be significantly less in offspring from ILI mothers than UC mothers.
In pregnancy, the adoption or pursuit of a sedentary lifestyle contributes to the development of co-morbid conditions such as hypertension, maternal and childhood obesity, gestational diabetes, pre-eclampsia, cesarean section and delivery of large-for-gestational-age infants (LGA). The aim of this study is to test the hypothesis that obese, pregnant women following a supervised moderate intensity physical conditioning program during the 2nd trimester of pregnancy will maintain a higher level of physical activity up to the end of pregnancy, as compared to women in the control group. We will also conduct a pilot study on the feasibility to examine the effects of the intervention on maternal fitness and neonatal anthropometry.
Use of tobacco is very high among Alaska Native women. The investigators are conducting a three phase study. The first phase will examine biomarkers of tobacco exposure in pregnant women and their newborns. The second phase is a qualitative study to translate the biomarker findings into intervention messages. The third phase is a pilot of the biomarker feedback intervention compared with a control condition.
This study includes a behavioral educational intervention that focuses on healthy eating and physical activity during pregnancy and the postpartum among women newly diagnosed with gestational diabetes mellitus (GDM).
The purpose of this study is to compare the effectiveness of a relationships based antenatal intervention (Mellow Bumps) against a comparison intervention (Chillout In Pregnancy) and also against the normal antenatal care which is received during pregnancy (Care As Usual). The Mellow Bumps intervention will seek to improve maternal anxiety and maternal sensitivity whilst the Chillout In Pregnancy intervention will aim to improve only maternal anxiety. This will allow the researchers to determine what type of intervention, if any, is most successful at improving the outcomes of the mother and child. This will be measured by looking at the mother's stress response, anxiety, depression and irritability, the baby's stress response and the interactions between the mother and the baby. Participants in the study will be pregnant women who would be between 20 and 30 weeks pregnant at the start of the antenatal intervention. Participants will be chosen to take part in one of the three conditions (Mellow Bumps, Chillout In Pregnancy or Care As Usual) at random. All participants will be asked to complete questionnaires and give saliva samples prior to the intervention. The questionnaires will also be repeated at the end of the intervention and at a follow up occurring eight to twelve weeks after birth. Consent will also be sought to take saliva samples from the baby before and after a routine blood test when the baby is five days old. This information will then be evaluated to establish the effectiveness of the proposed interventions.
