INTRODUCTION: To evaluate the largest vertical pocket (LVP) of amniotic fluid as a time-dependent factor to predict perinatal mortality in women with early preterm premature rupture of membranes (EPPROM). MATERIAL AND METHODS: Observational cohort study of singleton pregnancies with EPPROM <24 weeks. Termination of pregnancy (TOP) was considered if the LVP was <2 cm at 7 days. The maternal and neonatal characteristics of ongoing pregnancies were recorded. Prediction of perinatal mortality was estimated based on the influence of the LVP as a time-dependent factor after adjustment for maternal age, prior invasive procedure, and gestational age at EPPROM...

OBJECTIVE: Late miscarriage and preterm birth are frequently thought to be associated with inflammation and infection, although in most cases the underlying cause of early delivery remains unknown. The placenta is the organ that links mother and fetus during pregnancy, and postnatal examination may provide useful information about pathophysiology. The relationship between placental pathological lesions and predictive markers of early delivery has not been explored. We sought to characterize preterm deliveries according to placental pathology and relate these to the performance of reliable predictive markers, fetal fibronectin and cervical length...

BACKGROUND: When delivery is indicated prior to 34 weeks, many providers perform a cesarean delivery (CD) rather than induce labor based on perceptions of a high failure rate. Given the morbidity of CD, an accurate estimate of the success rate and factors associated with success in preterm induction of labor (IOL) is important in management decisions. OBJECTIVE: We sought to develop a prediction model for successful induction of labor in preterm patients using factors known at the time the decision is made to deliver...

STUDY QUESTION: Is supraphysiologic estradiol (E2) an independent predictor of low birth weight (LBW) in singletons born after fresh IVF-embryo transfer (ET) cycles? SUMMARY ANSWER: Our results suggest that E2 > 2500 pg/ml is an independent predictor for LBW in full-term singletons born to normal responder patients undergoing fresh IVF-ET cycles. WHAT IS KNOWN ALREADY: The pathogenesis of LBW in IVF singletons remains unknown. However, recent studies have suggested that the hyperestrogenic milieu generated during ovarian stimulation may create a sub-optimal peri-implantation environment, leading to placental dysfunction, and therefore, LBW...

Birgit Arabin, Ahmet A Baschat
Physiologic adaptations during pregnancy unmask a woman's predisposition to diseases. Complications are increasingly predicted by first-trimester algorithms, amplify a pre-existing maternal phenotype and accelerate risks for chronic diseases in the offspring up to adulthood (Barker hypothesis). Recent evidence suggests that vice versa, pregnancy diseases also indicate maternal and even grandparent's risks for chronic diseases (reverse Barker hypothesis). Pub-Med and Embase were reviewed for Mesh terms "fetal programming" and "pregnancy complications combined with maternal disease" until January 2017...

BACKGROUND: Rupture of membranes (ROM) before the onset of uterine contractions, particularly in pregnancies less than 37 weeks gestational age, is a common diagnostic problem in obstetrical practice. Timely detection of ROM is vital to support gestational age-specific interventions to optimize perinatal outcomes and minimize the risk of serious complications such as preterm delivery, fetal distress and maternal/fetal infections. Rapid bedside immunoassay tests designed to detect amniotic fluid proteins in cervicovaginal fluids have emerged as valuable clinical tools to provide timely ROM diagnosis...

Importance: Preeclampsia affects approximately 4% of pregnancies in the United States. It is the second leading cause of maternal mortality worldwide and may lead to serious maternal complications, including stroke, eclampsia, and organ failure. Adverse perinatal outcomes for the fetus and newborn include intrauterine growth restriction, low birth weight, and stillbirth. Many of the complications associated with preeclampsia lead to early induction of labor or cesarean delivery and subsequent preterm birth...

An accurate detection of preterm labor and the risk of preterm delivery before 37 weeks of gestational age is crucial to increase the chance of survival rate for both mother and the infant. Thus, the uterine contractions measured using uterine electromyogram (EMG) or electro hysterogram (EHG) need to have high sensitivity in the detection of true preterm labor signs. However, visual observation and manual interpretation of EHG signals at the time of emergency situation may lead to errors. Therefore, the employment of computer-based approaches can assist in fast and accurate detection during the emergency situation...

OBJECTIVE: The purpose of this study was to evaluate sonographic cervical length (CL) and granulocyte elastase (GE) in cervical secretion as predictors of preterm delivery in asymptomatic twin pregnancies. MATERIALS AND METHODS: This study prospectively enrolled asymptomatic twin pregnancies with CL < 25 mm at 22-29 weeks of gestation. All women were hospitalized for preterm labor, and the cervical secretion was obtained for GE testing on admission. The results of CL measurement and GE testing were reviewed, and the relationship between each variables and preterm delivery prior to 34 weeks of gestation was assessed...

BACKGROUND Nephrotic syndrome occurs very rarely, in only about 0.01%-0.02% of all pregnancies, and de novo minimal change disease during pregnancy is especially rare. Nephrotic syndrome and, especially, minimal change disease are highly responsive to steroids, and preterm labor may be avoidable if the maternal condition is improved with steroid therapy. Therefore, prompt diagnosis and proper management are critical to maternal and fetal outcome when severe proteinuria occurs during pregnancy. CASE REPORT A 30-year-old pregnant Japanese woman presented with systemic edema, oliguria, and severe proteinuria and hypoalbuminemia at 25 weeks of gestation, although she was normotensive...
