Filter by:To assess the role of uterine artery and maternal serum leptin and lipids and their combination in screening for pre-eclampsia and small-for-gestational-age (SGA) fetuses at 20-24 weeks of gestation
1. To test for equivalence in terms of catch-up growth between the 2 therapeutic regimens 2. To specify the best period of treatment 3. To assess the efficacy of treatment based on final adult height of these children
The purpose of this retrospective pilot study is to address the effect that obesity, in the absence of other comorbidities, has on birth weight. We wish to determine if obesity is a risk factor for small for gestational age (SGA) or intrauterine growth restricted (IUGR) infants in our clinic population. There have been many studies linking maternal obesity with fetal macrosomia, defined as fetal birth weight greater than 4500 grams. However, we have noted that a percentage of our obese patient population has delivered either an SGA or IUGR infant. SGA refers to a constitutionally small infant weighing less than the 10th percentile for age. This refers to a genetically normal infant. IUGR refers to a fetus whose growth has been restricted by influences other than normal genetics. Our study population will consist of all women over the age 18 who delivered a term infant either by vaginal delivery or cesarean section at Tulsa Regional Medical Center between July 1st 2004 and December 31st 2005. The diagnosis of obesity will be based upon a Body Mass Index (weight in kilograms/height in meters squared) of thirty or greater. We will look at the infant birth weight as recorded in the patient's chart. We will define SGA or IUGR as birth weight less than the 10th percentile for gestational age as defined previously. The control group will consist of women meeting the same criteria except they will have a BMI less than thirty but greater than 19.8 as low maternal weight is also a risk factor for IUGR. We will compare the average birth weight and the rates of SGA/IUGR infants between the two groups and analyze using the chi-squared method of analysis.
Growth retardation in utero may be caused by uteroplacental vascular insufficiency. When Doppler ultrasound studies of the umbilical artery are abnormal pathological intrauterine growth restriction (IUGR) can be diagnosed. IUGR fetuses have a higher mortality and morbidity, both perinatally and on the longer term. This is probably due to chronic malnourishment and hypoxia due to placental insufficiency. This placental dysfunction causes generation of harmful free oxygen radicals in the fetus. The IUGR fetus has a diminished antioxidative capacity which means these free radicals cannot be buffered sufficiently. This leads to fetal oxidative stress. Previous studies have shown that allopurinol can inhibit the cascades that lead to generation of free radicals. High dosed allopurinol also scavenges radicals and binds free iron without adverse effects on the fetus or mother. As IUGR is associated with placental insufficiency and excessive production of free radicals we hypothesize that antenatal allopurinol administration could lead to a decrease in oxidative stress in the mother and fetus and subsequent improvement of the maternal and/or neonatal outcome.
The objective of this trial will be to determine whether prophylactic low-molecular weight heparin therapy in pregnant women with the heterozygous Factor V Leiden and G20210A prothrombin gene mutations thrombophilia and a history of severe preeclampsia and/or severe fetal growth restriction reduces the risk of the composite outcome of preeclampsia, fetal growth restriction, or both.
To determine whether or not women with a history of having a baby with intrauterine growth retardation (IUGR) was more likely to have risk factors for cardiovascular disease versus women with a pregnancy not complicated by IUGR.
Pre-eclampsia (PE) and intrauterine growth restriction (IUGR) are common and important disorders of pregnancy. Both disorders are associated with an impairment of uteroplacental blood flow (UPBF). No effective therapy has been identified to reliably improve UPBF in these patients and typically, obstetric management involves interventional delivery, particularly problematic when remote from term. This study assess the hypothesis that epidural local anesthetics may improve UPBF in these patients.
To estimate the percentage of children with serum IGF-1 > 2 standard deviation (compared to a child of the same gender and age and without growth hormone (GH) deficiency) 9 months and 12 months after initiation of GH treatment.
The goal of the project is to show the effectiveness of individualized developmental care and intervention, which begins with the FGR preterm infant's admission to the newborn intensive care unit (NICU) and extends to 2 weeks (w) after full term equivalent age or 2w CA (corrected age for prematurity).
The objective of this pilot study is to prospectively evaluate amniotic fluid of pregnancies complicated by non-immune hydrops and severe symmetrical intrauterine growth restriction by tandem mass spectrometry for inborn errors of metabolism.
