Early embryonic loss and adverse birth outcomes are the major reproductive disorders that affect both human and animals. The LPS induces inflammation by interacting with robust cellular mechanism which was considered as a plethora of numerous reproductive disorders such as fetal resorption, preterm birth, teratogenicity, intrauterine growth restriction, abortion, neural tube defects, fetal demise, and skeletal development retardation. LPS-triggered overproduction of free radicals leads to oxidative stress which mediates inflammation via stimulation of NF-κB and PPARγ transcription factors...

Monochorionic twin pregnancies are at increased risk for adverse outcome compared to dichorionic twin pregnancies and singletons. Monochorionic-specific complications include twin-twin transfusion syndrome (TTTS), twin anemia-polycythemia sequence, single intrauterine fetal demise and its consequences on the co-twin, and selective intrauterine growth restriction. Whereas the natural history of monochorionic-specific complications carries a high risk of fetal death or severe neurologic disability, a framework now exists, based on well-designed clinical trials, for optimal treatment of these entities...

Zika virus (ZIKV) infection during pregnancy in humans results in intrauterine growth restriction, spontaneous abortion, and microcephaly. Here, we found that fetus-derived type I interferon (IFN-I) signaling can enhance anti-ZIKV responses and provide clinical benefits to the fetus. Because IFN-λ shares signaling cascades and antiviral functions with IFN-I, we investigated the in vivo effects of IFN-λ in ZIKV-infected pregnant mice. IFN-λ administration during mid-pregnancy reduced ZIKV burden in maternal and fetal organs and alleviated placental injuries and fetal demise...

OBJECTIVES: Polyhydramnios and placentomegaly are commonly observed in nonimmune hydrops fetalis (NIHF); however, whether their ultrasonographic identification is relevant for prognosis is controversial. We evaluated outcomes of fetal or neonatal death and preterm birth (PTB) in cases of NIHF alone and in those with polyhydramnios and/or placentomegaly (P/PM). METHODS: We conducted a retrospective cohort of singletons with NIHF evaluated between 1994 and 2013. Nonimmune hydrops fetalis was defined as 2 or more abnormal fluid collections, including ascites, pericardial effusion, pleural effusion, and skin edema...

This study used insurance claims data to evaluate obstetric outcomes in pregnant women with and without depression because population study for Asian women on the issue is limited. We identified 5,064 women with depression at pregnancy in 2005-2013, and 20,024 pregnant women without depression, frequency matched by age, pregnant year and parity. Obstetric events during pregnancy and deliveries were evaluated. The depression group had more events than comparisons for hyperemesis (39.3 vs. 35.5%), abortion (3...

Two cases of live caesarean scar ectopic pregnancies are presented. Beta human chorionic gonadotropin (b-hCG) values in both patients at presentation were 50 099 mIU and 297 969 mIU, respectively. Both were managed with intrasac potassium chloride injection to induce fetal demise and multiple dose methotrexate therapy. The time for b-hCG to become negative in both patients was 91 days and 119 days, respectively. Successful management of live caesarean scar pregnancies even with very high b-hCG is possible with minimally invasive approach...

BACKGROUND: Pregnant women with pulmonary hypertension (PH) are at risk for adverse cardiac outcomes, particularly at the time of labor and delivery. The purpose of this study is to define the impact of PH on pregnancy outcomes and the risk of major adverse cardiac events (MACE). METHODS AND RESULTS: The National Inpatient Sample was screened for hospital admissions of women delivering during the years 2003 to 2012. The primary outcome was MACE, a composite of death, cardiac arrest, cardiogenic shock, myocardial infarction, respiratory failure, arrhythmia, stroke, and embolic event...

Monochorionic (MC) twin pregnancies are known to carry a high risk of twin-to-twin transfusion syndrome (TTTS) that could lead to miscarriage and perinatal death. Demise of one fetus is frequently associated with co-fetal death. Fetal reduction by interstitial laser therapy is an effective procedure to prevent this outcome, but it may be associated with significant risks for both mother and fetus. Aplasia Cutis Congenita (ACC) may occur in up to 8% cases of fetal reduction by laser therapy. We report ACC in a preterm infant, a survivor of interstitial laser therapy for fetal reduction in MC pregnancy...

Acute fatty liver of pregnancy (AFLP) is a rare, often autosomal recessive disorder with a major risk for maternal and perinatal mortality and morbidity. In order to achieve a more favorable outcome, awareness of its clinical signs and symptoms and early recognition are of pivotal importance. Over a 5-year period 18 patients were diagnosed with AFLP (one twin, 19 babies). The most common sign and symptoms were jaundice, hypoglycemia, nausea and vomiting, encephalopathy, and hypertension. Abnormal laboratory test results included: elevated total/ conjugated (direct) bilirubin, AST, ALT, PT, APTT, creatinine, leukocyte count, and hypoalbuminemia...

Fetal growth restriction is commonly defined as an estimated fetal weight (EFW) that is below the 10th percentile for gestational age. It is associated with an increased risk of intrauterine demise, neonatal morbidity, and neonatal death; therefore, antenatal detection and surveillance with the optimization of delivery timing are necessary to improve pregnancy outcomes. If the estimated due date has been verified and the EFW is below the 10th percentile for gestational age, the underlying cause should be investigated, since the clinical management, outcome, and counseling options are largely dependent on the cause of the growth restriction...

INTRODUCTION: Fetal echogenic lung lesions (ELL) are the commonest pulmonary pathology diagnosed on antenatal sonography, and include congenital pulmonary airway malformations (CPAMs) and bronchopulmonary sequestrations. This study aimed to evaluate the predictive utility of the CPAM volume ratio (CVR) at presentation in a series of fetuses with ELLs at a tertiary Australian referral hospital. MATERIAL AND METHODS: Retrospective cohort study of all pregnancies with a prenatal diagnosis of an isolated fetal echogenic lung lesion managed at the Royal Women's Hospital, Victoria, Australia, between 2005 and 2015...

OBJECTIVE: To compare strategies for the timing of delivery in women with breast cancer and known cancer stage or hormone receptor subtype, and to determine the optimal gestational age for induction in regards to maternal-fetal outcomes. STUDY DESIGN: A decision-analytic model was designed comparing eight different strategies for scheduled delivery at 30, 31, 32, 33, 34, 35, 36, and 37 weeks gestation. Optimal breast cancer treatment was assumed to be delayed until after delivery...

BACKGROUND/PURPOSE: Elective preterm delivery (EPD) of a fetus with gastroschisis may prevent demise and ameliorate intestinal injury. While the literature on optimal timing of delivery varies, we hypothesize that a potential benefit may be found with EPD. METHODS: A meta-analysis of publications describing timing of delivery in gastroschisis from 1/1990 to 8/2016 was performed, including studies where either elective preterm delivery (group 1, G1) or preterm gestational age (GA) (group 2, G2) were evaluated against respective comparators...

The Zika virus (ZIKV) epidemic has resulted in congenital abnormalities in fetuses and neonates. Although some cross-reactive dengue virus (DENV)-specific antibodies can enhance ZIKV infection in mice, those recognizing the DENV E-dimer epitope (EDE) can neutralize ZIKV infection in cell culture. We evaluated the therapeutic activity of human monoclonal antibodies to DENV EDE for their ability to control ZIKV infection in the brains, testes, placentas, and fetuses of mice. A single dose of the EDE1-B10 antibody given 3 d after ZIKV infection protected against lethality, reduced ZIKV levels in brains and testes, and preserved sperm counts...

Zika virus infection during pregnancy can cause congenital abnormities or fetal demise. The persistence of Zika virus in the male reproductive system poses a risk of sexual transmission. Here we demonstrate that live-attenuated Zika virus vaccine candidates containing deletions in the 3' untranslated region of the Zika virus genome (ZIKV-3'UTR-LAV) prevent viral transmission during pregnancy and testis damage in mice, as well as infection of nonhuman primates. After a single-dose vaccination, pregnant mice challenged with Zika virus at embryonic day 6 and evaluated at embryonic day 13 show markedly diminished levels of viral RNA in maternal, placental, and fetal tissues...
