Filter by:The purpose of this study is t o evaluate levator ani morphology following normal vaginal delivery and cesarean section (elective and emergent), using three-dimensional (3D) ultrasound, and to study the effect of mode of delivery on female sexual function.
Operative vaginal delivery (with forceps or vacuums) is frequently performed secondary to maternal exhaustion, which leads to an inability to push effectively; 40% of operative vaginal deliveries at Prentice are for maternal exhaustion. The risk of severe birth trauma is increased three to four fold with operative delivery. This randomized, controlled trial will compare rates of operative vaginal delivery and severe birth trauma in two groups of women: (1) an intervention group who will participate in the antepartum Total Control® fitness and education program modified for pregnancy; and (2) a control group. Women will be recruited and followed from the second trimester until 6 weeks postpartum; all will complete validated questionnaires regarding their (1) level of worry and knowledge about their birthing experience (2) pelvic floor symptoms and quality of life (3) sexual function (4) satisfaction with their birthing experience and (5) level of depressive symptoms at various time points during and after their pregnancy. Obstetrical data will also be collected.
For 25 years, the twin pregnancy rate has regularly increased in the majority of European countries and in the United States, by 35% between 1981 and 2006. Increased use of medically assisted procreation and older maternal age are the two main causes. At the present time twin pregnancies represent nearly 20% of premature deliveries. The rate of very premature births (< 32-34 weeks) is 7 times higher in twin pregnancies than in singleton pregnancies. As prematurity accounts for 75% of neonatal morbidity and mortality, and extreme prematurity is the principal cause of neonatal mortality and of brain sequelae in twins, the search for a preventive treatment appears as a priority in perinatal medicine. The investigators recently showed in a prospective multicenter study that cervical ultrasound at 22 and 27 wks was a better predictive investigation of premature delivery < 34 wks than digital examination. Recently in a randomized trial in a population of short-cervix singleton pregnancies, the premature delivery rate decreased by 40% in the pessary group compared with the usual management group. No other trial of pessary use in short-cervix twin pregnancies was published today. Recently, in a historical comparison of twins with twin-to-twin transfusion syndrome treated with laser, Carreras et al. have showed a decreased rate of preterm delivery with the use of pessary in case of short cervix. The investigators wish to set up a randomized multicenter study in France in the population of short-cervix twin pregnancies to show a potential benefit of the pessary compared with simple surveillance.
This study evaluates generic emtricitabine(FTC) efficacy and safety in Chinese naive pregnant HBsAg positive patients in prevention of HBV vertical transmission. Single group patients were enrolled to receive emtricitabine till 24 weeks after delivery.
This study evaluates generic emtricitabine(FTC) efficacy and safety in Chinese naive pregnant chronic hepatitis B patients. Single group patients were enrolled to receive emtricitabine till 48 weeks after delivery.
At which deleterious cut off value of progesterone on day of HCG (P-hCG) in our IVF program should fresh embryo transfer (ET) be cancelled?
Background: - People with inborn errors of metabolism can t turn food into energy the right way. This can affect a person s growth and health. Researchers want to know how this condition affects a pregnant woman and her baby. Objectives: - To collect data from the medical records of women with an inborn error of metabolism. Also, to create a pregnancy registry of inborn errors of metabolism. Eligibility: - Women with an inborn error of metabolism who either: - have been pregnant in the past, - are currently pregnant, or - have recently talked with their doctor about becoming pregnant. Design: - This study will collect data only. No extra tests will be done. - Participants will be in the study for the length of their pregnancy and for 1 year after delivery. - Participants will answer questions about their family s health. - The participant s doctor will send their medical records to researchers. These may include data about: - Last health care visit before pregnancy - Blood, urine, ultrasound, or lab results during pregnancy - Delivery and recovery after delivery - Researchers will ask for the test(s) used to confirm pregnancy. - After the participant has her baby, researchers will ask for data about how the baby is doing. This may include when the baby is sitting, walking, talking, etc. - The data will be placed into a database. The database will not include the participant s name or identifying data.
The purpose of this study is to establish a tissue and data repository consisting of samples of human placentas, umbilical cord blood, and maternal blood, collected at the time of delivery. Specimens will be used in cellular, molecular, and functional studies to learn more about changes in placental structure and function, which can result in serious pregnancy complications and determine life-long health by programming the fetus for future metabolic and cardiovascular disease.
The purpose of this study is to identify the influences of pregnancy on breast milk and the effects of these on the health of babies during the first 2 months of life. The investigators hypothesize that overweight and obese mothers will have lower serum n-3 to n-6 PUFA ratios during pregnancy and postpartum than normal weight mothers and will be positively correlated with TNF-α, IL-1β, resistin, and negatively correlated ghrelin levels both in serum and in breast milk in postpartum.
Premature rupture of membranes (PROM) is diagnosed by demonstrating amniotic fluid in the vaginal canal before the onset of labor. The integrity of the amniotic membrane is compromised thereby increasing the risk of intrauterine infection and compression of the umbilical cord. PROM complicates 3% to 8% of pregnancies in the US and is responsible for 30% of preterm births. Intrauterine infection remains the most significant maternal and neonatal sequelae associated with PROM and this risk increases with the length of time from ruptured membrane to delivery. Induction of labor has been shown to reduce the rates of chorioamnionitis, endometritis and NICU admissions4. Specifically, induction of labor with prostaglandin agents followed by oxytocin, versus oxytocin alone has been shown to be effective for labor induction resulting in vaginal delivery. Management strategies for PROM have been controversial, and published studies on outcomes are over one to two decades old, which does not account for changes in clinical trends and practice patterns. Recently ACOG recommends that patients presenting at 37 weeks gestation or greater with PROM should be induced if not in labor, and "generally with oxytocin". In women with PROM without the onset of labor, the cervix is commonly unfavorable and induction with oxytocin alone may lead to an increased risk of cesarean section. With a c-section rate as high as 33%, women undergoing induction of labor have an increased risk of c-section and its associated morbidity and long term sequela. ACOG's recommendation for the use of oxytocin as the induction agent may be meant to avoid a theoretical increased risk of chorioamnionitis in this patient population however it does not take into account the status of the cervix, which may result in a increased risk of c-section. The purpose of the proposed study is to determine whether cervical ripening in women with PROM and an unfavorable cervix is associated with increase rates of vaginal delivery and decreased cesarean section rate compared to induction of labor with oxytocin alone. The investigators aim to determine the incidence of endometritis, and neonatal infection associated with PROM in the current medical environment of antibiotic prophylaxis and antenatal steroid use, taking into account the changes in patient characteristics.
