Intrahepatic cholestasis of pregnancy (ICP) represents the most common pregnancy-related liver disease in women. Women frequently present in the third trimester with pruritus and elevated serum bile acid and/or alanine transaminase levels. Clinical symptoms quickly resolve after delivery; however, recurrence in subsequent pregnancies has to be expected. Intrahepatic cholestasis of pregnancy is associated with increased perinatal complications, such as premature delivery, meconium staining of the amniotic fluid, respiratory distress, low Apgar scores, and even stillbirth...

OBJECTIVE: To compare different ultrasonographic fetal weight estimation formulas in predicting the fetal birth weight of preterm premature rupture of membrane (PPROM) fetuses. METHODS: Based on the ultrasonographic measurements, the estimated fetal weight (EFW) was calculated according to the published formulas. The comparisons used estimated birth weight (EBW) and observed birth weight (OBW) to calculate the mean absolute percentage error [(EBW-OBW)/OBW×100], mean percentage error [(EBW-OBW)/OBW×100)] and their 95% confidence intervals...

A monochorionic-diamniotic twin baby presented with intrauterine growth restriction and anuria. The baby was found to have bladder agenesis, a pelvic dysplastic horseshoe kidney, vertebral anomalies, a ventricular septal defect and facial dysmorphisms. It was surprising to find no abnormalities in amniotic fluid indices prenatally, suggesting the possibility of urine output that declined as the pregnancy proceeded. Some degree of twin-to-twin transfusion of amniotic fluid was also possible, which could have rescued the oligohydramnios known to be associated with kidney and urinary tract abnormalities...

It has long been assumed that establishment of the fetal microbiome commences with the birthing process. However, recent studies have found bacterial DNA in umbilical cord blood, placenta, amniotic fluid, meconium, and fetal membranes in healthy normal pregnancies, leading to suggestions that the seeding of the fetal microbiome may commence in utero long before delivery. The origins of the microbiota of the fetal gastrointestinal (GI) tract have not yet been conclusively determined, although bacterial translocation from the maternal circulation, or ascension from the vagina, are both likely to be contributing pathways...

The present study was conducted in pregnant rhesus monkeys to determine the rapidity and extent to which BPA reaches the fetal compartment following oral ingestion, and the 24-hr fate of BPA. To assess metabolism changes during the course of pregnancy, we compared BPA biotransformation during the second and third trimesters in the same animals, measuring the levels of sulfated, gluronidated, and free BPA in maternal serum, amniotic fluid, and fetal serum. All animals showed measurable unconjugated and conjugated BPA in the fetal compartment and slow clearance compared to maternal serum...

OBJECTIVE: To determine if apparently healthy post-term South Asian-born (SA) women were more likely to have abnormal post-term fetal surveillance than Australian- and New Zealand-born (AUS/NZ) women, whether those abnormalities were associated with increased rates of obstetric intervention and adverse perinatal outcomes, and whether SA women and their babies were at higher risk of adverse outcomes in the post-term period irrespective of their post-term surveillance outcomes. STUDY DESIGN: Post-term surveillance and perinatal outcomes of 145 SA and 272 AUS/NZ nulliparous women with a singleton post-term pregnancy were compared in a retrospective multicentre cohort analysis...

BACKGROUND: To determine whether the presence of intra-amniotic infection and elevated proinflammatory cytokine levels in amniotic fluid (AF) are associated with failure in the newborn hearing screen (NHS) test in very preterm neonates. METHODS: This is a retrospective cohort study of 112 premature singleton neonates born to women with preterm labor or preterm premature rupture of membranes at ≤32 wk. AF obtained through amniocentesis was cultured, and interleukin-6 (IL-6) and IL-8 levels were determined...

BACKGROUND: This study aimed to investigate the rate of coagulopathy progression in amniotic fluid embolism (AFE), using the level of fibrinogen. METHODS: We examined all cases of maternal death (46 cases) related to AFE between 2010 and 2013 in Japan (total number of deliveries: 4,291,459). Fibrinogen, blood loss from AFE onset to fibrinogen measurement, and time from onset to fibrinogen measurement were investigated. The correlations of fibrinogen with time from onset to fibrinogen measurement and blood loss at fibrinogen measurement were analyzed...

Communication between mother and offspring in mammals starts at implantation via the maternal-placental-fetal axis, and continues postpartum via milk targeted to the intestinal mucosa. MicroRNAs (miRNAs), short, noncoding single-stranded RNAs, of about 22 nucleotides in length, are actively involved in many developmental and physiological processes. Here we highlight the role of miRNA in the dynamic signaling that guides infant development, starting from implantation of conceptus and persisting through the prenatal and postnatal periods...

BACKGROUND: Spinal muscular atrophy (SMA) is caused by homozygous inactivation of the SMN1 gene. The SMN2 copy number modulates the severity of SMA. The 0SMN1/1SMN2 genotype, the most severe genotype compatible with life, is expected to be associated with the most severe form of the disease, called type 0 SMA, defined by prenatal onset. OBJECTIVE: The aim of the study was to review clinical features and prenatal manifestations in this rare SMA subtype. METHODS: SMA patients with the 0SMN1/1SMN2 genotype were retrospectively collected using the UMD-SMN1 France database...

During early gestation, nutrients are transported to the developing embryo via transporters in the uterine endometrium and chorioallantois. In the present study, we examined glucose transporters and and the cationic AA transporters , , and to test the hypotheses that 1) relative mRNA expression of transporters would be different among uteroplacental tissue type as gestation progresses and 2) concentrations of glucose and cationic AA would be different among target sites (placental compartments, serum, and histotrophic) and days of gestation...

BACKGROUND: Maternal sartan intake during pregnancy has been associated with several fetal/neonatal complications related to disturbed renal development. Description of cases: We present two cases of neonatal acute kidney injury (AKI) following valsartan administration during pregnancy and provide evidence for the use of novel AKI biomarkers in these neonates. The first case was a female neonate, delivered at 32+4 weeks of gestation after maternal valsartan intake from 24 to 32 gestational weeks...

The metanephric kidneys of the chicken embryo, along with the chorioallantoic membrane, process water and ions to maintain osmoregulatory homeostasis. We hypothesized that changes in relative humidity (RH) and thus osmotic conditions during embryogenesis would alter the developmental trajectory of embryonic kidney function. White leghorn chicken eggs were incubated at one of 25-30% relative humidity, 55-60% relative humidity, and 85-90% relative humidity. Embryos were sampled at days 10, 12, 14, 16, and 18 to examine embryo and kidney mass, glomerular characteristics, body fluid osmolalities, hematological properties, and whole embryo oxygen consumption...

Amniotic Fluid Embolism (AFE) is a catastrophic complication of pregnancy with high mortality rate. The most common clinical presentation is an abrupt onset of cardiopulmonary collapse. Here, we present an uncommon variant involving isolated disseminated intravascular coagulation that developed without antecedent cardiopulmonary disturbances. Both patients developed symptoms soon after delivery. Blood test was sent at 14 minutes postpartum for the second patient due to suspected amniotic fluid embolism. Fetal components were observed in the uterine veins of the lower uterine segments in both cases...

OBJECTIVE: Neutrophil extracellular traps (NETs) control microbial infections through their antimicrobial activities attributed to DNA, histones, granules, and cytoplasmic proteins (eg, elastase). Intra-amniotic infection is characterized by the influx of neutrophils into the amniotic cavity; therefore, the aim of this study was to determine whether amniotic fluid neutrophils form NETs in this inflammatory process. METHODS: Amniotic fluid samples from women with intra-amniotic infection (n = 15) were stained for bacteria detection using fluorescent dyes...

OBJECTIVE: To review the actions of galanin during pregnancy and to examine the existence of an association between galanin and birthweight as well as with gestational diabetes mellitus (GDM). RESULTS: Galanin concentrations in maternal circulation are similar in pregnant and non-pregnant status and have been correlated with body mass index (BMI). There is evidence of an association between birthweight and galanin concentrations in amniotic fluid during second trimester as well as galanin concentrations in umbilical cord at term...

Studies with the use of highly sensitive enzymatic sensor have shown the presence of various forms of nitrosyl iron complexes, including those undetectable by other methods, in living tissues. All these complexes are long-living compounds and constitute the major part of nitroso compounds in the blood, muscles, liquor, and amniotic fluid.

BACKGROUND: Gastroschisis is the most common major congenital anomaly managed by paediatric surgeons. The significance of certain associated antenatal ultrasound features in determining fetal outcome is under discussion. AIM: The study aims to define if associated antenatal ultrasound features of gastroschisis are useful prognostic markers for fetal outcome. By establishing the significance of features, including extra- and intra-abdominal bowel dilatation, stomach herniation, stomach dilatation, bowel matting, growth restriction, abnormal umbilical artery (UA) Doppler ultrasounds, and abnormal amniotic fluid volume, it is hoped clinicians will have enhanced ability to counsel parents about the likely outcomes for their infant...
