Filter by:Placental insufficiency is the source of preeclampsia (PE) and intrauterine growth retardation (IUGR). Current data demonstrate a significant beneficial effect of prophylactic use of aspirin on the recurrence of placental insufficiency and its complications, mainly preeclampsia, when started early in pregnancy. However, there is a significant heterogeneity in medical practice in Canada and around the world in terms of the dose of aspirin used. The objectives of this study are: 1) Evaluate whether a dose of 160 mg of aspirin is associated with greater improvement in placental function assessed by biochemistry (sFlt-1 and endoglin) and ultrasound (uterine artery Doppler) than a dose of 80 mg in women with a history of PE, 2) Assess whether the change is dependent on platelet aggregation measured by a test used in several Canadian centers (PFA-100).
Intrauterine growth restriction is being suspected in cases where the fetal estimated weight is less then the 10 th percentile for its gestational age. Abdominal circumference is the most influenced measurement in this cases. Head circumference on the other hand can be or not be influenced. Previous studies have shown that transverse cerebellar diameter (TCD) is constant to gestational age and is not influenced by IUGR.Other showed lower TCD in IUGR fetuses. We would like to study the differences in cerebellar, vermian and corpus callosum growth between normal to IUGR fetuses and between symmetrical and asymmetrical IUGR. In this observational study we will include pregnant women between 28-37 gestational week with a singleton otherwise normal pregnancies. We will measure the fetal TCD, vermian distances and the CC, abdominal circumference, head circumference and femur length. we will compeer these measurements according to the following groups:normal fetuses, symmetrical and asymmetrical IUGR.
Intrauterine growth retardation (IUGR) occurs in approximately 3 to 10% of singleton pregnancies, in 9.1% of all twins and 9.9% of monochorionic twins. IUGR in monochorionic twins typically affects only one of the fetuses (selective IUGR or SIUGR). Spontaneous demise of the SIUGR twin can occur, and may result in concomitant demise (up to 40% risk) or severe neurologic handicap (up to 30% risk) of the other twin. These complications result from exsanguination of the appropriately grown (AGA) twin into the demised SIUGR twin through placental vascular communications. Because the adverse effects to the AGA twin of the spontaneous demise of the SIUGR twin are mediated through placental vascular anastomoses, we have proposed obliterating such anastomoses via endoscopic fetal surgery. We have developed a technique that allows us to identify the vascular anastomoses present in monochorionic placentas. Briefly, deep AV communications are identified on the surface of the placenta by noting that the terminal end of the artery of one of the fetuses does not have a corresponding returning vein to the same fetus. We have speculated that the separation of the circulations may be of benefit in monochorionic twins affected by SIUGR by preventing the adverse effects that may result from the spontaneous demise of the IUGR twin. Our goal is to evaluate with a randomized clinical trial the outcome of SIUGR managed either expectantly or with SLPCV. Study procedures will begin with confirmation of the diagnosis and screening criteria at the Qualified Clinical Center. The patient will sign the appropriate consents and then be randomized to her treatment group. Enrollment data will be submitted to the research coordinator in Coordinating Center in Tampa. Expectant management patients will be treated by the referring physicians. Laser patients will be treated at Coordinating Center in Tampa General Hospital or qualified laser center. They may return to the referring center for follow-up. After delivery, outcome data will be sent to the research coordinator in Coordinating Center in Tampa.
Identification of the presence of proangiogenic immune cells in normal human placentas may enable predication of some pregnancy disorders.
The purpose of this study is to determine whether sildenafil is effective and safe in the treatment of fetal growth restriction.
To evaluate the effect of continuous and intermittent administration of Genotonorm on stature in short prepubertal children with intra-uterine growth retardation
The risk of venous thromboembolism increases in pregnancy. Thrombophilia whether genetic or acquired, is a hypercoagulable disorder that may increase the risk of venous thromboembolic events. Clinically, these events are presented as maternal deep vein thrombosis and pulmonary emboli. Thrombophilias are also associated with adverse fetal outcomes including intrauterine growth restriction, intrauterine fetal death, severe preeclampsia, placental abruption and recurrent abortions. Pregnant women who experienced one or more of the above complications are advised to be examined for the presence of the genetic or the acquired form of thrombophilia. Low molecular weight heparin prophylaxis, an anticoagulant, is advised for pregnant women with a history of thromboembolism, and many experts recommend prophylaxis for pregnant patients with a known thrombophilia and history of adverse pregnancy outcomes associated with these hypercoagulable states. Physiologic changes in normal pregnancy, including weight gain, increased renal clearance and volume of distribution, may decrease the availability of low molecular weight heparin (Enoxaparin or Dalteparin), or produce a less predictable response in pregnant women compared with nonpregnant women. There are no clear recommendations for use of prophylactic low molecular weight heparin in pregnancy. Clinicians tend to use doses suggested for nonpregnant patients. Regarding pregnant patients taking enoxaparin or dalteparin, the American College of Obstetricians and Gynecologists states that "because of the lack of data regarding adequate dosing during pregnancy, anti-factor Xa levels may be monitored". Two recently published studies demonstrated that plasma anti-factor Xa levels during pregnancy were lower than expected, indicating that many pregnant patients may receive a subprophylactic dosing. Our objective is to check pregnancy outcome among thrombophilic women treated with an adjusted enoxaparin thromboprophylaxis dosage according to anti-factor Xa plasma levels compared to women with fixed dosage.
Pre-eclampsia and intra uterine growth restriction (IUGR) represent major complications for pregnant women, with a high related maternal and fetal morbidity and mortality. It is now widely admitted that these pathologies, which can concern up to 7% of pregnancies, are in relation with hypo-perfusion of the placenta because of an early deficient trophoblast invasion and uterine vascular remodelling.Advances in ultrasound imaging now permit non invasive 3D volume and Doppler signal quantification using automatic acquisitions.Quantitative comparison of volumes and Doppler parameters between control pregnancies and IUGR ought to confirm the theory of UTERO-placental hypo-perfusion. This technique might allow an earlier prediction for IUGR. The aim of this study is to evaluate the interest of 3D Doppler quantification as a new screening tool for pre eclampsia and IUGR.
The purpose of the study is to learn more about the development of small for gestational age (SGA) preterm infants and whether focusing on the infant's behavior has a positive effect on outcome. The study hypotheses state: 1) High risk severely SGA preterm infants will profit from detailed neuropsychological assessment, psychoeducational recommendations and practical guidance for caregiving, as well as formal educational and emotional support for the family and the professional care team. 2) Neuropsychological education and guidance for community-based early intervention providers caring for SGA preterm infants after their discharge is effective in promoting improved outcome.
Low birth weight (LBW; birth weight<2,500g) is the most important determinant of mortality and morbidity in the neonatal period. It is also a very important factor in predicting nutritional status, health and development in childhood. It even influences health in adult life, contributing to the vicious cycle of disease and poverty. The high rate LBW in DCs represents therefore a major public health problem. Maternal chronic energy deficiency is assumed to be a major determinant of the problem in these countries along with prenatal micronutrient deficiencies. A large body of recent evidence points out that multiple micronutrient supplementation as such has only a modest beneficial effect on fetal growth. Therefore, it is expected that providing these multiple micronutrients in a food supplement covering energy requirement needs of pregnant women will have an effect of public health importance on children's health. This study has the objective of improving children's health by improving birth outcome and fetal growth through the provision of a food supplement enriched in multimicronutrients during pregnancy. This research includes 2 constituents: 1. a pilot phase during which dietary behavior of pregnant women is assessed as a component for optimal fetal growth 2. a randomized, placebo-controlled trial, including 1300 pregnant women aimed at testing 2 hypotheses: supplementing pregnant women with a food supplement containing a multivitamin-minerals mix will improve fetal growth; improved fetal growth will have a positive effect on health and growth during infancy. The trial is planned in Hounde District, Burkina Faso, in collaboration with Centre Muraz, which plays a leader role in research and services providing at the district level and in policy recommendations at the national level. This will ensure that the study findings are incorporated into on-going district programs with possible replication at the national level. The research lasts from February 2006 to August 2009.
