Filter by:This study aims to assess the prevalence of sleep disorder breathing in pregnant women with a singleton gestation who develop hypertensive disorder of pregnancy (HDP) compared to women without HDP, when matched for gestational age and body mass index.
In normal pregnancy the spiral arteries in the placental bed are invaded by trophoblast, which becomes incorporated into the vessel wall and replaces the endothelium, muscular layer and neural tissue
STEPUP is a 12-week randomized clinical trial among 126 postpartum women with pregnancies complicated by hypertensive disorders. Participants will be randomized to a control arm and receive a Fitbit or an intervention arm. The intervention arm will receive a Fitbit and set a step count goal, receive daily feedback via text about whether they reached their goal, and will be placed in virtual teams with other participants where they can win points for their team if they meet their daily goals. The main study outcomes will be increase in mean step count and change in psychosocial survey measures.
This research study is being performed to see if women diagnosed with early preterm Hemolysis, Elevated Liver Enzymes, Low Platelets (HELLP) syndrome (estimated gestational ages of 23-30 weeks) benefit from a medication called eculizumab (ECU). This drug blocks a part of the immune system called complement. By blocking this part of the immune system, eculizumab may stop or reverse the progression of the HELLP syndrome disease. The investigators will also look to see if this drug is effective and benefits both the mother and fetus.
This study aims to assess the effect of epidural anesthesia on the optic nerve sheath diameter in parturients with preeclampsia.
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.
Preeclampsia is a disorder of widespread vascular endothelial malfunction and vasospasm that occurs after 20 weeks' gestation and can present as late as 4-6 weeks postpartum
The aim of this study is to make it easier to predict late-onset preeclampsia at 11-14 weeks of pregnancy. This will be done by measuring certain proteins in the mother's blood together with obtaining the mother's medical history, ultrasound of the mother's blood supply to the uterus, and her blood pressure. All expectant mothers who meet the inclusion criteria will be invited to participate in the study, and those that agree will have the above mentioned factors measured at their first trimester scan appointment. The data will be registered in an online database, and the blood samples will be saved in a biobank at the hospital. When the women have then given birth around six months later, the data will be analyzed, and whether or not the individual woman ended up developing preeclampsia will be found out from her medical records. It will then be possible to see if blood samples, medical history, blood supply to the uterus, and/or blood pressure are connected to development of preeclampsia.
Preeclampsia (PE) is a morbid and potentially lethal complication of pregnancy and is more common in women with specific risk factors. Aspirin (ASA) is currently the only prophylactic therapy for preeclampsia in high-risk women to be recognized by the US Preventive Task Force and should be initiated early in the second trimester of pregnancy, before 16 weeks of gestation. However, currently there is no literature comparing various low-dose ASA formulations in the risk reduction of PE. In the United States, the currently available low-dose ASA is over the counter and is found in 81mg tablets. Therefore, when clinicians initiate therapy with low dose ASA, they may prescribe 1 or 2 tablets of 81mg aspirin per day depending on personal preference and cannot be assisted by evidence to guide their decision.This study aims to determine the incidence of preterm PE or PE with severe features in women taking either 81mg or 162mg in a randomized setting, from a single center. The investigators hypothesize that the information gained from this trial will permit a more accurate sample size calculation for a larger clinical trial powered to accept or reject our testing hypothesis. If our hypothesis is rejected and 162mg of daily ASA is not associated with a lower incidence of severe or preterm PE compared to 81mg, this may be due to lack of power to detect a smaller effect. The investigators would then evaluate the feasibility and results and determine whether a larger trial is reasonable.
The investigators plan to enroll women with PE prospectively to evaluate incremental cardiovascular risk in those who have PE with severe features. This study includes detailed echocardiographic evaluation at several time points. With the current proposal, the investigators aim to collect blood to evaluate several biomarkers to determine if there is a correlation with short and medium-term cardiovascular risk. This opens the door to earlier detection, treatment and improved cardiovascular outcomes.
