Dongying Zhao, Lile Zou, Xiaoping Lei, Yongjun Zhang
In the present study, we aimed to explore gender differences in infant mortality and neonatal morbidity in mixed-gender twin pairs. Data were obtained from the US National Center for Health Statistics Linked Birth-Infant Death Cohort. A total of 108,038 pairs of mixed-gender twins were included in this analysis. Among the mixed-gender twins, no significant difference in the odds of fetal mortality between male twins (1.05%) and female co-twins (1.04%). However, male twins were at increased odds of neonatal mortality (adjusted OR 1...

Post-mortem magnetic resonance (PMMR) imaging is rapidly emerging as an alternative, "less invasive", and more widely accepted investigative approach for perinatal deaths in the UK. PMMR has a high diagnostic accuracy for congenital and acquired fetal neuropathological anomalies compared to conventional autopsy, and is particularly useful when autopsy is non-diagnostic. The main objectives of this review are to describe and illustrate the range of common normal and abnormal central nervous system (CNS) findings encountered during PMMR investigation...

Major obstetric hemorrhage is the leading cause of maternal morbidity and mortality. In rare cases, life-threatening hemorrhage in pregnant women may result from abnormal adherence of placenta. Three grades of abnormal placental attachment are defined according to the depth of invasion: placenta accreta, placenta increta, and placenta percreta. An important risk factor for placenta abnormal adherence of placenta is placenta previa in the presence of a uterine scar. The increased prevalence of cesarean section, uterine surgery, and increasing parturient age and parity have led to an increased incidence of abnormal placentation, from one in 2,500 a quarter century ago, to one in 533 deliveries currently...

Zika fever, a mosquito-borne infectious disease caused by Zika virus (ZIKV), is an epidemic disease for which no effective therapy has been established. The recent outbreaks of ZIKV in Brazil and French Polynesia have been linked to a considerable increase in the incidence of fetal microcephaly and other diseases such as Guillain-Barre syndrome. Because there is currently no specific therapy or vaccine, the early exploitation of a method to prevent expansion of ZIKV is a high priority. To validate commonly used antiviral drugs, we evaluated the effect of ribavirin, a drug used to treat hepatitis C with interferon-β (IFN-β), on ZIKV replication...

Walker-Warburg syndrome (WWS) is a severe form of congenital muscular dystrophy secondary to α-dystroglycanopathy with muscle, brain, and eye abnormalities often leading to death in the first weeks of life. It is transmitted in an autosomal recessive pattern, and has been linked to at least 15 different genes; including protein O-mannosyltransferase 1 (POMT1), protein O-mannosyltransferase 2 (POMT2), protein O-mannose beta-1,2-N acetylglucosaminyltransferase (POMGNT1), fukutin (FKTN), isoprenoid synthase domain-containing protein (ISPD), and other genes...

Placental function is complex and influenced by various factors; furthermore, it depends on a delicate balance between cell proliferation, cell differentiation, and cell death. Bcl-2 and Bax proteins are key apoptosis regulators and are considered to play an important role in the maintenance of both dynamic balance and integrity of many tissues. Changes in Bcl-2 and Bax expressions have been described during different developmental stages in normal human placentas. Studies furthermore indicated several pathological placental changes to be related to abnormal Bcl-2 and Bax expressions...

Clinical studies showed beneficial effects of magnesium sulfate regarding the risk of cerebral palsy. However, regimen protocols fluctuate worldwide and risks of adverse effects impacting the vascular system have been reported for human neonates, keeping open the question of the optimal dosing. Using clinically relevant concentrations and doses of magnesium sulfate, experiments consisted of characterizing, respectively, ex vivo and in vivo, the effects of magnesium sulfate on the nervous and vascular systems of mouse neonates by targeting neuroprotection, angiogenesis, and hemodynamic factors and in measuring, in human fetuses, the impact of a 4-g neuroprotective loading dose of magnesium sulfate on brain hemodynamic parameters...

BACKGROUND: Sickle cell anemia causes severe complications and premature death. Five common β-globin gene cluster haplotypes are each associated with characteristic fetal hemoglobin (HbF) levels. As HbF is the major modulator of disease severity, classifying patients according to haplotype is useful. The first method of haplotype classification used restriction fragment length polymorphisms (RFLPs) to detect single nucleotide polymorphisms (SNPs) in the β-globin gene cluster. This is labor intensive, and error prone...

Pulmonary fibrosis is the leading cause of death in systemic sclerosis (SSc). Sirtuin1 (SIRT1) is a deacetylase with known anti-inflammatory and anti-fibrotic activity in the liver, kidney and skin. The role of SIRT1 in SSc-related pulmonary fibrosis is unknown. In the present work, we determined that the expression of SIRT1 in peripheral blood mononuclear cells of SSc patients with pulmonary fibrosis is lower than that in SSc patients without pulmonary fibrosis. In in vivo studies of Bleomycin-induced lung fibrosis in mice, SIRT1 activation with Resveratrol reduced collagen production when it was administered either prophylactically during the inflammatory stage or after the development of fibrosis...

We aimed to investigate whether the lung-to-thorax transverse area ratio (LTR) immediately before birth is of diagnostic value for the prediction of postnatal short-term outcomes in cases of isolated left-sided congenital diaphragmatic hernia (CDH). We retrospectively reviewed the cases of fetal isolated left-sided CDH managed at our institution between April 2008 and July 2016. We divided the patients into 2 groups based on LTR immediately before birth, using a cut-off value of 0.08. We compared the proportions of subjects within the 2 groups who survived until discharge using Fisher's exact test...
