OBJECTIVES: A narrow subpubic arch angle (SPA) has been associated with a higher risk of operative delivery and prolonged labor. The aim of this study was to evaluate the correlation between SPA and labor outcome in a cohort of women delivering a large-for-gestational-age (LGA) fetus. METHODS: An observational study involving two Italian tertiary centers (Parma and Rome) was carried out. Nulliparous women referred to the antepartum clinic between 35 and 39 weeks due to an increased risk of having an LGA fetus at birth were prospectively selected for the study purpose...

STIL (SCL/TAL1 interrupting locus) is a core component of the centriole duplication process. STIL mutations have been associated with both autosomal recessive primary microcephaly (MCPH) and holoprosencephaly. In this report, we describe a family with multiple miscarriages and 2 terminations of pregnancy due to marked fetal microcephaly, delayed cortical gyrification, and dysgenesis of the corpus callosum. Whole exome sequencing allowed us to identify novel compound heterozygous mutations in STIL. The mutations lie, respectively, in the CPAP/CENPJ and the hsSAS6 interacting domains of STIL...

Toxoplasmosis is one of the most important causes of foodborne illnesses and inflammatory complications, as well as congenital disorders. Promiscuous Toxoplasma is transmitted by contaminated food and animal produce, water, vegetations, fruits and sexually through semen. Toxoplasma infects nucleated cells with a unique tropism for muscles and central nervous system and a mind bugging malicious effect. Pregnant women with acute or reactivated toxoplasmosis can transmit Toxoplasma via transplacental to the fetus...

Accumulating evidence support a causal link between Zika virus (ZIKV) infection during gestation and congenital microcephaly. However, the mechanism of ZIKV-associated microcephaly remains unclear. We combined analyses of ZIKV-infected human fetuses, cultured human neural stem cells and mouse embryos to understand how ZIKV induces microcephaly. We show that ZIKV triggers endoplasmic reticulum stress and unfolded protein response in the cerebral cortex of infected postmortem human fetuses as well as in cultured human neural stem cells...

The accurate measurement of blood pressure (BP) in pregnancy is essential to guide medical decision making that affects both mother and fetus. The aim of this systematic review was to determine the accuracy of ambulatory, home, and clinic BP measurement devices in pregnant women. We searched Ovid MEDLINE, The Cochrane Library, EMBASE, CINAHL EBSCO, Clinicaltrials.gov, International Clinical Trials Registry Platform, and dabl from inception through August 3, 2017 for articles that assessed the validity of an upper arm BP measurement device against a mercury sphygmomanometer in pregnant women...

PURPOSE: The prenatal natural history of intralobar and extralobar bronchopulmonary sequestrations (BPSs), including lesion growth patterns and need for prenatal intervention, have not been fully characterized. We review our series of BPSs to determine their natural history and outcomes in the context of the need for prenatal intervention. METHODS: A retrospective review of the pre/postnatal course of 103 fetuses with an intralobar (n=44) or extralobar BPS (n=59) managed at a single institution between 2008 and 2015 was performed...

BACKGROUND: Primary hydrothorax is a congenital anomaly affecting 1 in 10,000-15,000 pregnancies. The natural history of this condition is variable with some fetuses having spontaneous resolution and others showing progression. The associated pulmonary hypoplasia leads to increased perinatal morbidity and mortality. Optimal prenatal intervention remains controversial. METHODS: After obtaining the Institutional Review Board approval, a retrospective review of all patients evaluated for a fetal pleural effusion in the Fetal Diagnosis and Treatment Center at The University of Michigan, between 2006 and 2016 was performed...

Profiles of heavy metals chromium (Cr), manganese (Mn), arsenic (As), lead (Pb), cadmium (Cd) and micronutrients ferrum (Fe), copper (Cu), zinc (Zn), selenium (Se) in maternal and umbilical cord blood clots were investigated for assessing placenta function in the transport of micronutrients or heavy metal pollutants. Correlations between contents of elements in the two tissues were also analyzed. Results demonstrated significantly lower levels of Cr, Pb and Cd in umbilical cord blood clots than in maternal blood clots, and negative relationship between lead levels in maternal and umbilical cord blood (r = -0...

Uterus transplantation was firstly tested with animal trials sixty-five years ago. Despite several successful attempts in human subjects, the different procedures still lay at the experimental stage, in need of further studies and investigations before they can be considered as standard clinical practices. Uterus transplant cannot be regarded as a life-saving procedure, but rather a method to restore woman ability to procreate, when lost, thus improving her quality of life. Uterus transplant is a complex surgical procedure and presents significant health threats...

Ganciclovir (GCV) has been implicated in the development of testicular alterations. Exposure on gestational day (GD) 10 in rats induced permanent effects, including focal reduction or absence of germ cells (Sertoli cell-only tubules). Because the timing of exposure can be critical for testicular effects, we exposed rat dams to 300 mg/kg GCV (three 100mg/kg subcutaneous injections) on GD10, 14 and 19, when germ cells have high rates of migration, proliferation and are mitotically quiescent, respectively. Males exposed to GCV in utero on GD10 and 14 were evaluated for androgenization markers, serum and fecal androgens, and testicular histomorphometry at adulthood...

To examine whether cancer survivors diagnosed before age 35 years are more likely to have offspring with chromosomal abnormalities than their siblings, chromosomal abnormalities were determined in a population-based cohort of 14 611 offspring (14 580 live-born children and 31 fetuses) of 8945 Danish cancer survivors and 40 859 offspring (40 794 live-born children and 65 fetuses) of 19 536 siblings. Chromosomal abnormalities include numeric and structural abnormalities. Odds ratios were estimated by multiple logistic regression models comparing the risk of chromosomal abnormalities among survivors' offspring with that in siblings' offspring...

INTRODUCTION: Williams syndrome (WS), an autosomal dominant condition linked to gene deletions on chromosome 7, can cause supravalvular aortic narrowing and death. WS-associated mutations are believed to disrupt arterial elastin fibers, causing smooth muscle malformation, endomysial fibrosis and severe hypertension. Previous studies demonstrated arterial ultrastructural anomalies in adult WS patients. It is not presently known if the arterial phenotype of WS is also present in utero. CASE REPORT: A 34-week stillborn was delivered to a 28-year-old with genetically confirmed WS...

Maternal obesity can cause complications for both women and their offspring for generations. Therefore, we intended to verify the repercussions of induction of transgenerational obesity on biochemical parameters, reproductive performance, and congenital anomaly frequency in Wistar rats. Female rats were used from successive generations. The female rats of parental generation (F0, n=10) were mated to obtain their offspring (F1 generation). F1 female rats received a monosodium glutamate (MSG) solution to induce obesity (n=07) or vehicle (control, n=06) during the neonatal period...

INTRODUCTION: Patient who was undergoing hemodialysis (HD) thrice weekly usually gain 1 to 4 kg of weight in interdialytic period, mainly due to fluid accumulation by ingestion of water. Ultrafiltration (UF) during HD will be need to remove fluid excess to avoid severe medical complications secondary to fluid overload. However, in pregnant woman UF can increase the episodes of intradialytic hypotension which may lead to placental ischemic injury and predispose to fetal distress. There is little information about safe fluid amount withdrawn by UF during pregnancy...

In recent decades, women with significant medical conditions have increasingly chosen to become pregnant. This has broadened and intensified the interface between obstetrics and internal medicine, a collaboration which has always needed cooperation but which increasingly demands open discussion and planning to ensure optimal outcomes for mother and fetus. The aims of this article are to describe the state of obstetric medicine practice in Australia and New Zealand, including its history and development, the training and education curriculum, organisation of its service delivery, and potential opportunities for research and collaboration...

REVIEW
Rebecca Fischer-Betz, Christof Specker
Systemic lupus erythematosus (SLE) is a chronic inflammatory autoimmune disease with a high prevalence in females of childbearing age. Pregnancy in SLE nowadays has favorable outcomes for the majority of women. However, flares of disease activity, preeclampsia, fetal loss, and preterm birth are well-known risks in such pregnancies. Anti-SS-A(Ro)/SS-B(La) antibodies put fetuses at risk for congenital heart block and neonatal lupus. Several risk factors for adverse pregnancy outcomes have been identified. Women with antiphospholipid antibodies or antiphospholipid syndrome and lupus nephritis represent a group with high risk for obstetric complications...

AIM: Gather "proof-of-concept" evidence of the adverse developmental potential of cotinine (a seemingly benign biomarker of recent nicotine / tobacco smoke exposure). METHODS: Pregnant C57 mice drank nicotine or cotinine-laced water for 6wks from conception (NPRE = 2% saccharin+100μg nicotine/ml; CPRE = 2% saccharin + 10μg cotinine/ml) or 3wks after birth (CPOST = 2% saccharin + 30μg cotinine/ml). Controls drank 2% saccharin (CTRL). At 17±1weeks (male pups; CTRL n=6; CPOST n=6; CPRE n=8; NPRE n=9) we assessed (i) cardiovascular control during sleep; (ii) arterial reactivity ex vivo; (iii) expression of genes involved in arterial constriction / dilation...

Acrylamide (AA), an environmental pollutant, has been linked to neurotoxicity, genotoxicity and carcinogenicity. AA is widely used to synthesize polymers for industrial applications, is widely found in Western-style carbohydrate-rich foods and cigarette smoke, and can also be detected in human umbilical cord blood and breast milk. This is the first study that demonstrated the cardiac developmental toxicity of AA in zebrafish embryos. Post-fertilization exposure to AA caused a clearly deficient cardiovascular system with a shrunken heart and abortive morphogenesis and function...

Folate status during pregnancy is important for fetal development and health. The placenta plays an important role in supplying the fetus with folate. Most women with epilepsy continue their medication during pregnancy. In the present study, we aimed to evaluate the effects of 16 antiepileptic drugs, clinically used for treatment of epilepsy, on folic acid uptake in two in vitro placental models, BeWo and JEG-3 cells. Short-term exposure to antiepileptic drugs had no effects on [3H]-folic acid uptake by BeWo cells...
