BACKGROUND: Postpartum haemorrhage is a major obstetric risk worldwide. Therefore risk factors need to be investigated to control for this serious complication. A recent systematic review and meta-analysis revealed that the use of both serotonergic and non-serotonergic antidepressants in pregnancy are associated with a higher risk of postpartum haemorrhage. However, use of antidepressants in pregnancy is often necessary because untreated depression in pregnancy is associated with adverse maternal and neonatal outcome, such as postpartum depression, preterm birth and dysmaturity...

Incomplete ossification of the cuboidal bones is a common finding in premature and dysmature foals, and possibly in foals with hypothyroidism. Radiographs of the carpus and tarsus should be performed in any high-risk foal to obtain a diagnosis. Goals of treatment include limiting weight bearing and exercise. The prognosis is guarded depending on the degree of incomplete ossification.

Background Fetomaternal hemorrhage (FMH) is a poorly understood entity that can have significant clinical effects. Flow cytometry is a reliable and relatively new method for FMH diagnosis. The objective of this study was to correlate placental pathology with FMH detected by flow cytometry. Methods All patients with available placentas and FMH flow cytometric testing performed from 2009 to 2015 were retrospectively reviewed. Cases were defined as ≥0.10% fetal red blood cells (RBCs) in the maternal circulation while controls contained <0...

In a subset of children experiencing prolonged febrile seizures (FSs), the most common type of childhood seizures, cognitive outcomes are compromised. However, the underlying mechanisms are unknown. Here we identified significant, enduring spatial memory problems in male rats following experimental prolonged FS (febrile status epilepticus; eFSE). Remarkably, these deficits were abolished by transient, post hoc interference with the chromatin binding of the transcriptional repressor neuron restrictive silencing factor (NRSF or REST)...

OBJECTIVE: To determine associations between patient and clinical factors with postnatal brain metabolism in term neonates with congenital heart disease (CHD) via the use of quantitative magnetic resonance spectroscopy. STUDY DESIGN: Neonates with CHD were enrolled prospectively to undergo pre- and postoperative 3T brain magnetic resonance imaging. Short-echo single-voxel magnetic resonance spectroscopy of parietal white matter was used to quantify metabolites related to brain maturation (n-acetyl aspartate, choline, myo- inositol), neurotransmitters (glutamate and gamma-aminobutyric acid), energy metabolism (glutamine, citrate, glucose, and phosphocreatine), and injury/apoptosis (lactate and lipids)...

OBJECTIVE: In humans, stem cell factor (SCF), produced by cumulus granulosa cells during the follicular phase, plays a crucial role in follicular development. Remarkably, polycystic ovary syndrome (PCOS), one of the main reasons affecting women fertility, is accompanied by some abnormal follicles. Is there a relationship between SCF and PCOS? This study aimed to compare the expression of SCF in follicle and serum from patients with and without PCOS undergoing in vitro fertilization (IVF) treatment and to investigate the potential relationship between aberrant SCF expression and PCOS...

Fetal growth restriction (FGR) is a major complication of human pregnancy, frequently resulting from placental vascular diseases and prenatal malnutrition, and is associated with adverse neurocognitive outcomes throughout life. However, the mechanisms linking poor fetal growth and neurocognitive impairment are unclear. Here, we aimed to correlate changes in gene expression induced by FGR in rats and abnormal cerebral white matter maturation, brain microstructure, and cortical connectivity in vivo. We investigated a model of FGR induced by low-protein-diet malnutrition between embryonic day 0 and birth using an interdisciplinary approach combining advanced brain imaging, in vivo connectivity, microarray analysis of sorted oligodendroglial and microglial cells and histology...

Dural arteriovenous fistula (DAVF) of the transverse sinus with ophthalmic manifestations in young children are rare. We reviewed two cases of direct AVF of the transverse sinus with ocular manifestations managed at our institution. The first, a 2.5 years old male child presented with left exophthalmos. Angiography revealed AVF between the occipital artery and the transverse sinus. The second, a 2 years old female child, complained of left exophthalmos. Imaging studies showed bilateral direct AVFs of the transverse sinus with bilateral dysmaturation of the sigmoid sinus...

IMPORTANCE: Intrinsic connectivity networks (ICNs), important units of brain functional organization, demonstrate substantial maturation during youth. In addition, interrelationships between ICNs have been reliably implicated in attention performance. It is unknown whether alterations in ICN maturational profiles can reliably detect impaired attention functioning in youth. OBJECTIVE: To use a network growth charting approach to investigate the association between alterations in ICN maturation and attention performance...

Structural magnetic resonance imaging (MRI) scans at high spatial resolution can detect potential foci of early brain dysmaturation in children with autism spectrum disorders (ASD). In addition, comparison between MRI and behavior measures over time can identify patterns of brain change accompanying specific outcomes. We report structural MRI data from two time points for a total of 84 scans in children with ASD and 30 scans in typical controls (mean age time one = 4.1 years, mean age at time two = 6...

BACKGROUND: Tuberous sclerosis complex (TSC) is a multisystem disorder that results from mutations in the TSC1 or TSC2 genes, leading to constitutive activation of the mammalian target of rapamycin (mTOR) signaling pathway. Cortical tubers represent typical lesions of the central nervous system (CNS) in TSC. The pattern of cortical layering disruption observed in brain tissue of TSC patients is not yet fully understood, and little is known about the origin and phenotype of individual abnormal cell types recognized in tubers...

REVIEW
Jin-Ah Park, Jeffrey J Fredberg
Hallmarks of asthma include chronic airway inflammation, progressive airway remodeling, and airway hyperresponsiveness. The initiation and perpetuation of these processes are attributable at least in part to critical events within the airway epithelium, but the underlying mechanisms remain poorly understood. New evidence now suggests that epithelial cells derived from donors without asthma versus donors with asthma, even in the absence of inflammatory cells or mediators, express modes of collective migration that innately differ not only in the amount of migration but also in the kind of migration...

Premature birth is highly prevalent and associated with neurodevelopmental delays and disorders. Adverse outcomes, particularly in children born before 32 weeks of gestation, have been attributed in large part to white matter injuries, often found in periventricular regions using conventional imaging. To date, tractography studies of white matter pathways in children and adolescents born preterm have evaluated only a limited number of tracts simultaneously. The current study compares diffusion properties along 18 major cerebral white matter pathways in children and adolescents born preterm (n = 27) and full term (n = 19), using diffusion magnetic resonance imaging and tractography...

To determine whether transplanted amniotic membrane mesenchymal stem cells (AMSCs) ameliorated the premature senescent phenotype of Bmi-1-deficient mice, postnatal 2-day-old Bmi-1(-/-) mice were injected intraperitoneally with the second-passage AMSCs from amniotic membranes of β-galactosidase (β-gal) transgenic mice or wild-type (WT) mice labeled with DiI. Three reinjections were given, once every seven days. Phenotypes of 5-week-old β-gal(+) AMSC-transplanted or 6-week-old DiI(+) AMSC-transplanted Bmi-1(-/-) mice were compared with vehicle-transplanted Bmi-1(-/-) and WT mice...

Anti-platelet specific antibody is one of the most important reasons leading to thrombocytopenia and megakaryocyte dysmaturity. The detection of platelet autoantibodies is an important step in the diagnosis of ITP because of the absence of specific clinic feature. The monoclonal antibody-specific immobilization of platelet antigens (MAIPA) has become a "gold standard" for determination of PLT specific antibody, which has high specificity and low sensitivity. However, this assay is time-consuming and tedious work...
