Postpartum Care in the NICU Multi-Site

Parents of infants admitted to the neonatal intensive care unit (NICU) face unique challenges in caring for their own health after giving birth. The demands of having a critically ill infant often make it difficult or impossible to attend postpartum care appointments, and research shows that NICU mothers are significantly more likely than other new mothers to develop postpartum depression and other health conditions, including hypertensive disorders of pregnancy. However, these conditions frequently go undetected and untreated because standard postpartum care systems are not designed to address the needs of NICU mothers, who often prioritize being present in the NICU over their own needs. The PeliCaN (Postpartum Care in the NICU) Multi-Site trial will test whether trained postpartum doulas supporting mothers directly in the NICU can help close postpartum care gaps. Study doulas will provide emotional support, help mothers monitor their blood pressure, screen for postpartum depression, assist with scheduling and attending postpartum care visits, and connect families to community resources while their infant is in the NICU and after discharge for up to 6 months. The study team will enroll approximately 756 mothers across 13 NICUs in the Metro-Philadelphia area. Participating NICUs will be randomly assigned to groups on a stepped-wedge schedule to begin offering the doula intervention. Mothers enrolled before their site begins the doula intervention will receive standard postpartum care and support; mothers enrolled after their site transitions to the intervention period will receive doula support. All participants will complete surveys at enrollment and at 6 months after birth and will have their medical records reviewed. The study's main goals are to determine whether having a doula in the NICU helps mothers to receive recommended comprehensive postpartum care within the first 12 weeks after birth and will assess whether doula support reduces symptoms of postpartum depression and increases maternal transition to primary adult care by 6 months postpartum. The study will also examine the experience of implementing doulas in the NICU across multiple hospital sites among intervention participants and NICU staff members.

Cerebroplacental Ratio (CPR) and Amniotic-Umbilical-to-Cerebral Ratio (AUCR), in in Women With Hypertensive Disorders of Pregnancy.

The primary aim of this study is to evaluate the predictive value of the Amniotic-Umbilical-to-Cerebral Ratio (AUCR) in predicting composite adverse perinatal outcomes in women with hypertensive disorders of pregnancy and to compare its predictive performance with the traditional Cerebroplacental Ratio (CPR)

Breathing for Two: Inspiratory Muscle Strength Training for Supporting Healthy Blood Pressure in Pregnancy

This is an interventional study that will test whether a breathing exercise called Inspiratory Muscle Strength Training (IMST) can safely and effectively lower blood pressure during late pregnancy. The goal is to see if a home-based breathing training can help prevent or reduce high blood pressure disorders in pregnancy. The main objectives are to make sure the training is safe and tolerable for pregnant women and to examine blood pressure and blood vessel health. Participants in their third trimester will be randomly assigned to either do moderate resistance IMST or a minimal resistance sham IMST, for 5 to 8 minutes a day over six weeks.

Vascular Biomarkers Predictive of the Progression From Hypertensive Disorders in Pregnancy to Preeclampsia in Pregnant Women

Hypertension during pregnancy remains a leading cause of maternal and fetal morbidity and mortality. The frequency (5 to 10% of pregnancies) and potential severity of these diseases, both for the mother and the child, are reasons for standardizing and optimizing medical practices. The cause of hypertension during pregnancy is quite complex, as it depends on a number of factors. Among the hypertensive disorders in pregnancy (HDP), the pathophysiology of pre-eclampsia (one of the most studied in terms of severity) remains poorly understood. The evolution of international guidelines in recent years has made it possible to distinguish various HDP, but schematically we distinguish two main entities by the existence of proteinuria from and after the 20th week of amenorrhea and by maternal-fetal complications, more serious in pre-eclampsia than in gestational hypertension. Acute placental vasculature and blood flow abnormalities were observed during gestational hypertension and preeclampsia, and maybe due to generalized vascular endothelial activation and vasospasm resulting in systemic hypertension and organ hypoperfusion. Endothelial dysfunction (ED) and abnormal expression of several specific blood biomarkers are now well accepted as characteristics of preeclampsia as a leader. However, the progression of any HDP to preeclampsia is possible, but difficult to predict. By way of example, among between 15 and 40 % of gestational hypertension cases progress to preeclampsia, suggesting that it is the same worsening disease. ED could be pre-existing (chronic, white-coat or masked hypertension) but also at the origin of gestational hypertension (unclassified hypertension, transient pregnancy hypertension), and subsequent development of preeclampsia through an imbalance between pro- and anti-angiogenic factors. An imbalance of pro-angiogenic and anti-angiogenic proteins can testify to ED, as can adequate levels of endothelial microparticles. The main objective of this research is to assess the presence of urinary endothelial microparticles in stable pregnant women with hypertensive disorder of pregnancy as a marker for the occurrence of pre-eclampsia during pregnancy.
