Over the last few years, scientific interest in the cytokine IL-17A has intensified as its role in human health and disease has been elucidated. Discovered almost a quarter century ago, IL-17A is known to have poor biologic activity when acting alone, but attains robust actions when working synergistically with potent mediators of proinflammatory immune responses, such as IL-6 and IL-8. IL-17A is produced by specialized innate immune cells that protect host barriers from the outside world. Like sentries, these innate immune cells can "sound the alarm" through increased production of IL-17A, causing activation and recruitment of primed neutrophils and monocytes when pathogens escape initial host defenses...

OBJECTIVES: Although the efficacy of thoracoamniotic shunting (TAS) for fetal hydrothorax is well-recognized, the coexistence of hydrops fetalis is still a clinical challenge. The preoperative determinants of shunting efficacy are not fully understood. In this study, we aimed to investigate the perinatal and postnatal outcomes of hydrops fetalis with pleural effusion treated by TAS using a double-basket catheter, and to discuss the preoperative factors predictive of patients who will benefit from TAS...

Jacqueline H Wolf
When physicians performed cesarean sections in the nineteenth century, they customarily sought agreement from all present before proceeding. In contrast, after the introduction of electronic fetal monitoring in the late 1960s, obstetricians obtained permission for a cesarean by offering a choice that ensured consent-give birth by cesarean or give birth vaginally to a damaged or dead baby. This article argues that the manner in which physicians obtained consent for cesareans in the nineteenth century was one factor that kept the cesarean rate low, while the manner in which physicians obtained consent in the late twentieth and early twenty-first centuries was one factor driving up the cesarean rate...

BACKGROUND: Fetal anemia is often assumed to be due to red cell alloimmunization and Parvovirus infection, and can lead to hydrops fetalis and death in utero. Other causes, such as mutations of hemoglobin alpha, are less commonly considered. METHODS: We report 7 cases with fetal anemia causing hydrops fetalis. Serial Doppler ultrasound for measurement peak systolic velocity (PSV) of middle cerebral artery (MCA) was used for evaluation of fetal anemia. Fetal anemia is suggested if the MCA/PSV ratio is >1...

Human parvovirus B19 (B19V) infection of human erythroid progenitor cells (EPCs) induces a DNA damage response and cell cycle arrest at late S phase, which facilitates viral DNA replication. However, it is not clear exactly which cellular factors are employed by this single-stranded DNA virus. Here, we used microarrays to systematically analyze the dynamic transcriptome of EPCs infected with B19V. We found that DNA metabolism, DNA replication, DNA repair, DNA damage response, cell cycle, and cell cycle arrest pathways were significantly regulated after B19V infection...

The progress of axonal degeneration (AxD) following injury or insult impacts both recovery from axonal transection and protection of axons from diverse insults, or axonopathy. Here we provide evidence that increases in capase-6 (Casp6) expression and action contribute to the progression of AxD. The expression of Casp6 protein and mRNA in distal branches of sensory axons undergoing AxD was confirmed. We developed and utilized a new model of axonopathy in live mice by serially visualizing the viability of cutaneous axons in the ear pinna that expressed an axonal YFP transgene, in response to capasaicin-induced AxD...

Fetal growth restriction and related placental pathologies such as preeclampsia, stillbirth, and placental abruption are believed to arise in early pregnancy when inadequate remodeling of the maternal spiral arteries leads to persistent high-resistance and low-flow uteroplacental circulation. The consequent placental ischaemia, reperfusion injury, and oxidative stress are associated with an imbalance in angiogenic/antiangiogenic factors. Many interventions have centered on the prevention and/or treatment of preeclampsia with results pertaining to fetal growth restriction and small-for-gestational-age pregnancy often included as secondary outcomes because of the common pathophysiology...

BACKGROUND: Neonatal encephalopathy (NE) affects 2-4/1000 live births with outcomes ranging from negligible neurological deficits to severe neuromuscular dysfunction, cerebral palsy and death. Hypoxic ischemic encephalopathy (HIE) is the sub cohort of NE that appears to be driven by intrapartum events. Our objective was to identify antepartum and intrapartum factors associated with the development of neonatal HIE. METHODS: Hospital databases were searched using relevant diagnosis codes to identify infants with neonatal encephalopathy...

Severe fetal growth restriction (FGR) affects 1:500 pregnancies, is untreatable and causes serious neonatal morbidity and death. Reduced uterine blood flow (UBF) is one cause. Transduction of uterine arteries in normal and FGR animal models using an adenovirus (Ad) encoding VEGF isoforms, increases UBF and improves fetal growth in utero. Understanding potential adverse consequences of this therapy before first-in-woman clinical application is essential. OBJECTIVE: To determine whether Ad...

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...

Background: The most frequent myeloproliferative neoplasms are essential thrombocythemia and chronic myelogenous leukemia, which usually manifests with thrombocytosis. Only essential thrombocythemia is associated with morbidity during pregnancy (recurrent miscarriages, intrauterine fetal death, small for gestational age and preeclampsia). The aim of this paper is to describe outcomes of pregnancy in women with myeloproliferative neoplasms seen at a single academic institution. Methods: Data were collected retrospectively from 2002 to 2015...

BACKGROUND: In a variety of animal species, hyperthermia in pregnancy has been recognized as teratogenic. Hyperthermia interferes with protein synthesis via heat-shock proteins, which can entail membrane disruption, cell death, vascular disruption, and placental infarction. This can induce severe fetal malformations or death. Fever during pregnancy, especially during embryogenesis, has also been associated with congenital malformations in human offspring. The purpose of this large cohort study of clinically recognized pregnancies was to investigate whether fever during first trimester was associated with an increased risk of congenital malformations in the offspring...
