Filter by:This is a research study to understand the changes in the heart and the cardiovascular system that may occur in women who develop high blood pressure during pregnancy.
To determine if low dose aspirin reduces the incidence of hypertensive disorders of pregnancy (gestational hypertension, preeclampsia, eclampsia, and HELLP syndrome) in pregnant women with stage 1 hypertension and elevated blood pressure.
Identifying modifiable factors that contribute to preeclampsia risk associated with assisted reproduction can improve maternal health. Recent studies have shown an increased risk for hypertensive disorders of pregnancy after in vitro fertilization, particularly for pregnancies occurring during a hormone replacement therapy such a donor egg recipient and a frozen embryo transfer. This risk may be partly attributable to the degree by which the assisted reproductive treatment affects the maternal hormonal environment, when the corpus luteum is a major source of reproductive hormones. On the other hand, cryopreserved embryos are usually thawed and replaced in in a natural or hormonally manipulated cycle; on this point, frozen embryo transfer is associated with better perinatal outcome regarding preterm birth and low birth weight yet higher risk of large for gestational age and macrosomia compared to fresh transfer. The objective of our study is to investigate whether the absence of corpus luteum adversely affects pregnancy and to analyse if there are differences in the perinatal outcomes due to differences in the endometrial preparation protocol for a frozen embryo transfer.
This is a pilot study assessing fMRI changes and neurocognitive function in women with pre-eclampsia and healthy controls. Neurocognitive testing will be done during pregnancy and after delivery up to 2-6 weeks postpartum. fMRI will be done after delivery up to 2-6 weeks postpartum. The aims of this pilot study are therefore to 1) Determine the frequency and nature of co-morbid DTI white matter patency and fMRI functional connectivity changes in women with pre-eclampsia/eclampsia and 2) Determine the relationship between DTI white matter patency and fMRI functional connectivity changes to measurable alterations in cognitive function in this patient population. The aims of this pilot study are therefore to 1) Determine the frequency and nature of co-morbid DTI white matter patency and fMRI functional connectivity changes in women with pre-eclampsia/eclampsia and 2) Determine the relationship between DTI white matter patency and fMRI functional connectivity changes to measurable alterations in cognitive function in this patient population.
The study will compare agreement of invasive blood pressure measurements with non-invasive blood pressure measurements measured with a conical blood pressure and large standard upper arm rectangular cuff in morbidly obese severely hypertensive (systolic blood pressure > 160 mmHg) parturients.
This study will recruit women with post partum pre-eclampsia and match them to controls without postpartum pre-eclampsia to identify an epigenetic signature that is specific to women with post partum pre-eclampsia to help characterize the underlying pathophysiology of post partum pre-eclampsia.
This study is recruiting two groups of women over the age of 18; those who are pregnant and who have pre-eclampsia; and those who are pregnant but do not have pre-eclampsia. The aim is to test a new method of diagnosing and monitoring pre-eclampsia and thus prevent the long-term damage it can cause to the baby's health. Untreated, pre-eclampsia can lead to seizures in pregnancy (eclampsia) and may prove fatal for mother and child. Currently the only effective treatment for pre-eclampsia is control of the mother's blood pressure until it is safe to deliver the baby. The timing of delivery is kept under constant review by the medical team, who must balance the risk to the mother of developing eclampsia against the risk to the baby of being born too early (premature). If pre-eclampsia can be diagnosed early, there is a greater chance of being able to treat it effectively. We know that women with pre-eclampsia often have exaggerated reflexes in their limbs (hyperreflexia) and that this may be linked to the risk of seizures. Measuring these reflexes might therefore be a useful way to diagnose and monitor pre-eclampsia, but doing this is not easy, so we want to assess whether measuring other reaction times might similarly help assess the risk of seizures. One possibility is by measuring the reaction time as we flick our eyes to follow a moving target, using an instrument called a saccadometer, which is worn on a head-band, a little like a head-torch. By comparing the results between these groups and the non-pregnant women, we will be able to see if reaction times from the saccadometer are altered in women with pre-eclampsia, and, if so, whether saccadometry might be useful in helping doctors decide the best time for safe delivery.
The main objective of this trial is to study the occurrence of preeclampsia in recipients of donated oocytes receiving aspirin at an early stage during pregnancy and to compare the results with those obtained in patients receiving placebo.
This is a double blinded, placebo-controlled trial to determine if IV dexamethasone more quickly than placebo assists resolution of Posterior Reversible Encephalopathy Syndrome (PRES) encountered in eclamptic patients. All patients regardless of assignment to placebo or steroid will receive standard therapy to include magnesium sulfate, blood pressure medications and diuretics. We hypothesize that the addition of dexamethasone to standard therapy will accelerate CNS recovery more quickly than standard management without dexamethasone.
Phenylephrine administration is associated with reductions in CO and SctO2 compared with ephedrine when used for blood pressure management in women with pre-eclampsia undergoing cesarean delivery under spinal anesthesia.
