Preeclampsia (PE), a hypertensive disorder of pregnancy, is increasing as a major contributor to perinatal and long-term morbidity of mother and offspring. PE is thought to originate from ischemic insults in the placenta driving the release of pro-hypertensive anti-angiogenic (sFlt-1) and pro-inflammatory (TNFα) factors into the maternal circulation. While the increased incidence of PE is hypothesized to be largely due to the obesity pandemic, the mechanisms whereby obesity increases this risk are unknown...

Importance: Initially discovered in 1947, Zika virus infection received little notoriety as a tropical disease until 2015 when an outbreak of microcephaly cases was reported in Brazil. Zika is a single-stranded RNA arbovirus of the Flaviviridae family. The primary source of infection in humans stems from Aedes aegypti mosquito bites but can also occur through sexual, blood, and perinatal transmission. With expectations that 3 to 4 million people across the Americas will be infected over the next year, the World Health Organization has declared this event a Public Health Emergency of International Concern...

Background Perinatal stroke causes most hemiparetic cerebral palsy. Ipsilateral connections from nonlesioned hemisphere to affected hand are common. The nonlesioned primary motor cortex (M1) determines function and is a potential therapeutic target but its neurophysiology is poorly understood. Objective We aimed to characterize the neurophysiological properties of the nonlesioned M1 in children with perinatal stroke and their relationship to clinical function. Methods Fifty-two participants with hemiparetic cerebral palsy and magnetic resonance imaging-confirmed perinatal stroke and 40 controls aged 8 to 18 years completed the same transcranial magnetic stimulation (TMS) protocol...

BACKGROUND: Preeclampsia and intrauterine fetal growth restriction (IUGR) are two of the most common causes of maternal and perinatal morbidity and mortality. Current methods of predicting those at most risk of these conditions remain relatively poor, and in clinical practice past obstetric history remains the most commonly used tool. Aspirin and, in women at risk of preeclampsia only, calcium have been demonstrated to have a modest effect on risk reduction. Several observational studies and randomised trials suggest that low molecular weight heparin (LMWH) therapy may confer some benefit...

BACKGROUND: Neonatal sonography of the brain is now an essential part of newborn care, particularly in high risk and unstable premature infants. Cranial ultrasound is the most available and easily repeatable imaging technique for the neonatal brain showing brain development and the most frequently occurring forms of cerebral injury in the preterm and terms. This study aims to assess the importance of cranial ultrasound as an investigatory modality for high-risk neonates and to find out the morphology of various cerebral lesions and correlate clinically...

BACKGROUND: Language impairment (LI) risk is increased for perinatally acquired human immunodeficiency virus-infected (PHIV) and perinatally exposed to HIV but uninfected (PHEU) youth. This study evaluates the persistence of LI in these groups. METHODS: The Clinical Evaluation of Language Fundamentals was repeated on participants of the Pediatric HIV/AIDS Cohort Study Adolescent Master Protocol 18 months postbaseline. Regression models identified factors associated with change in standardized score (SC) and the resolution or development of LI...

BACKGROUND: Combination antiretroviral therapy has led to increased survival among youth with perinatally acquired HIV (PHIV). However, cognitive deficits continue to be common. Histopathological studies in adults have found HIV concentrated in subcortical structures, which are involved in sensory processing, movement, and higher-order cognition that emerges with development. METHODS: We conducted magnetic resonance imaging and cognitive testing in 40 youth with PHIV at one site of the Adolescent Master Protocol of the Pediatric HIV/AIDS Cohort Study...

BACKGROUND: The chronically instrumented fetal sheep is a widely used animal model to study fetal brain development in health and disease, but no methods exist yet to interrogate dedicated brain cell populations to identify their molecular and genomic phenotype. For example, the molecular mechanisms whereby microglia or astrocytes contribute to inflammation in the brain remain incompletely understood. NEW METHOD: Here we present a protocol to derive primary pure microglial or astrocyte cultures from near-term fetal sheep brain, after the animals have been chronically instrumented and studied in vivo...

BACKGROUND: Studies have shown that hypospadias is associated with placenta-mediated pregnancy complication (PMPC). The role of placental lesions is still unclear. We aimed to examine the association between hyposadias and placental pathology, and the effect of PMPC. METHODS: Using data from the U.S. Collaborative Perinatal Project in 1959-1966, we identified 15,780 male subjects (167 hypospadias) for analysis. Detailed placental examinations were conducted following a standard protocol...

OBJECTIVE: In the TRUFFLE study on outcome of early fetal growth restriction women were allocated to three timing of delivery plans according to antenatal monitoring strategies based on reduced computerized cardiotocographic heart rate short term variation (c-CTG STV) , early Ductus Venosus (DV p95) or late DV (DV noA) changes. However, many infants were per protocol delivered because of 'safety net' criteria, or for maternal indications, or 'other fetal indications' or after 32 weeks of gestation when the protocol was not applied anymore...

BACKGROUND: CenteringPregnancy (CP) is a multifaceted group based care-model integrated in routine prenatal care, combining health assessment, education, and support. CP has shown some positive results on perinatal outcomes. However, the effects are less obvious when limited to the results of randomized controlled trials: as there are few trials and there is a variation in reported outcomes. Furthermore, former research was mostly conducted in the United States of America and in specific (often high risk) populations...

This historical cohort study aimed to assess the relationship between antenatal maternal C-reactive protein (CRP) level and neonatal outcome preterm premature rupture of membranes (PPROM). We reviewed the records of 70 singleton pregnancies with PPROM between 24 and 34 weeks. Maternal CRP levels of neonates with respiratory distress syndrome, neonatal sepsis, grade 3-4 intraventricular haemorrhage and stage 2-3 necrotizing enterocolitis, perinatal mortality were compared with those without these complications...

INTRODUCTION: Although the majority of singleton births after in vitro fertilization (IVF) are uncomplicated, studies have suggested that IVF pregnancies may be independently associated with low birth weight (LBW), preterm birth (PTB), and perinatal mortality. These outcomes complicate multiple gestations as expected, but have also been reported in singletons. A multiple embryo implantation model allows for assessment of the early in utero environment, and therefore, assessment of any maternal constraints on developing fetuses...

BACKGROUND: Approximately 25 % of pregnant women suffer from a high level of Fear of Childbirth (FoC), as assessed by the Wijma Delivery Expectancy Questionnaire (W-DEQ-A, score ≥66). FoC negatively affects pregnant women's mental health and adaptation to the perinatal period. Mindfulness-Based Childbirth and Parenting (MBCP) seems to be potentially effective in decreasing pregnancy-related anxiety and stress. We propose a theoretical model of Avoidance and Participation in Pregnancy, Birth and the Postpartum Period in order to explore FoC and to evaluate the underlying mechanisms of change of MBCP...

AIMS: To compare the prevalence and severity of periodontal diseases between 180 perinatally HIV-infected (PHIV) and 118 perinatally HIV-exposed and uninfected (PHEU) youth in a cross-sectional study conducted at 11 clinical sites in the United States and Puerto Rico from the Adolescent Master Protocol study of the Pediatric HIV/AIDS cohort study (PHACS) network. METHODS: Several analyses were conducted, employing the current CDC/AAP classification for periodontitis and incorporating a definition of gingivitis based on a bleeding on probing (BOP) threshold, and analyses based on more detailed whole-mouth, intra-oral regionally, site-based and tooth-based criteria of BOP, plaque levels, pockets depths and clinical attachment levels...

Immersion in water during labor or delivery has been popularized over the past several decades. The prevalence of this practice in the United States is uncertain because it has not been studied in births outside of the home and birth centers, and the data are not recorded on birth certificates. Among randomized controlled trials included in a 2009 Cochrane systematic review that addressed immersion in the first stage of labor, results were inconsistent with regard to maternal benefits. Neither the Cochrane systematic review nor any individual trials included in that review reported any benefit to the newborn from maternal immersion during labor or delivery...

BACKGROUND: Depression is a common antenatal mental disorder and is associated with an increased risk of adverse effects on the fetus and significant morbidity for the mother; if untreated it can also continue into the post-natal period and affect mother-infant interactions. There has been little research evaluating the effectiveness or cost-effectiveness of antenatal psychological interventions for antenatal depression, particularly for mild to moderate disorders. International guidelines recommend a stepped care approach starting with Guided Self Help, and the aim of this exploratory trial is to investigate Guided Self Help modified for pregnancy...

Amniotic fluid embolism (AFE) is a rare but serious and potentially deadly complication of pregnancy that is unpreventable and unpredictable. Most AFE events occur during labor; however, approximately one third happen during the immediate postpartum period. Presentation is abrupt and thought to be an abnormal response to fetal materials entering maternal circulation through the placental insertion site. Care providers must recognize the signs and symptoms of AFE and react quickly in effort to treat potential complications...

BACKGROUND: Intrauterine growth retardation (IUGR) is a major risk factor for perinatal mortality and morbidity. Thus, there is a compelling need to introduce sensitive measures to detect IUGR fetuses. Routine third trimester ultrasonography is increasingly used to detect IUGR. However, we lack evidence for its clinical effectiveness and cost-effectiveness and information on ethical considerations of additional third trimester ultrasonography. This nationwide stepped wedge cluster-randomized trial examines the (cost-)effectiveness of routine third trimester ultrasonography in reducing severe adverse perinatal outcome through subsequent protocolized management...
