Using a mouse model of intrauterine inflammation, we have demonstrated that exposure to inflammation induces preterm birth and perinatal brain injury. Mesenchymal stem cells (MSCs) have been shown to exhibit immunomodulatory effects in many inflammatory conditions. We hypothesized that treatment with human adipose tissue-derived MSCs may decrease t...

PRLR(I146L) is the first identified gain-of-function variant of the prolactin receptor (PRLR) that was proposed to be associated with benign breast tumorigenesis. Structural investigations suggested this hydrophobic core position in the extracellular D2 domain to be linked to receptor dimerization. Here, we used a mutational approach to address how...

Objective To evaluate associations between prepregnancy lifestyle factors, psychologic distress and adverse pregnancy outcomes among female survivors of childhood cancer. Study Design We examined pregnancies of 1192 female participants from the Childhood Cancer Survivor Study. Generalized linear models, adjusted for age at diagnosis, age at pregnan...

Objective Most studies of tocolytics are underpowered to assess drug effects on rare adverse neonatal outcomes. Our aim was to optimize statistical power to assess the influence of sulindac on the rare but severe outcome of necrotizing enterocolitis (NEC) by performing a case-control study. Study Design A priori sample size of 78 in each group was ...

Objective Primary human trophoblasts were previously shown to be resistant to viral infection, and able to confer this resistance to nontrophoblast cells. Can trophoblasts protect nontrophoblastic cells from infection by viruses or other intracellular pathogens that are implicated in perinatal infection? Study Design Isolated primary term human tro...

Objective Antenatal magnesium (anteMg) is used for various obstetric indications including fetal neuroprotection. Infants exposed to anteMg may be at risk for respiratory depression and delivery room (DR) resuscitation. The study objective was to compare the risk of acute cardiorespiratory events among preterm infants who were and were not exposed ...

Objective We sought to identify serum biomarkers of early spontaneous preterm birth (SPTB) using semiquantitative proteomic analyses. Study Design This was a nested case-control study of pregnant women with previous SPTB. Maternal serum was collected at 19-24 and 28-32 weeks’ gestation, and analyzed by liquid chromatography-multiple reaction monito...

Objective This planned secondary analysis of the Outcomes Following Vaginal Prolapse Repairs and Midurethral Sling trial assessed whether treatment knowledge differed between randomized groups at 12 months and whether treatment success was affected by treatment perception. Study Design Sham suprapubic tension-free vaginal tape (TVT) incisions were ...

Our prospective study demonstrates that noninvasive prenatal analysis of cell-free deoxyribonucleic acid from maternal plasma is an accurate advanced screening test with extremely high sensitivity and specificity for trisomy 21 (>99%) but with less sensitivity for trisomies 18 and 13. Despite high sensitivity, there was modest positive predictive v...

Second-stage cesarean is associated with an increased risk of endometritis compared with first-stage cesarean. Further studies will determine whether different infection preventive strategies are needed at second-stage cesareans to reduce endometritis.
