BACKGROUND: Retinopathy of prematurity (ROP) is an adverse outcome of preterm birth (PTB) and is a leading cause of childhood blindness. The relationship between the subtypes of PTB with ROP is understudied. OBJECTIVE: To investigate if there is a difference in the incidence of type 1 or type 2 ROP in infants with PTB resulting from spontaneous preterm labor (SPTL), a medical indication (MIPTB), or preterm-premature rupture of the membranes (PPROM). STUDY DESIGN: A retrospective cohort study of 827 infants screened for ROP who delivered at a single tertiary care center in Colorado...

BACKGROUND: Myocardial dysfunction occurs in a variety of fetal disorders. Findings from adult cardiology, where n-terminal pro-B-type natriuretic peptide (nt-proBNP) is an established biomarker of left ventricular dysfunction have been extended to fetal life. Since fetal blood sampling is technically challenging we investigated amniotic fluid nt-proBNP for its suitability to diagnose fetal myocardial dysfunction. METHODS: Ultrasound, Doppler examination and echocardiography was applied to classify cases and controls...

Mother-to-child transmission (MTCT) of hepatitis B virus (HBV) remains high even with the proper use of active-passive immunoprophylaxis in newborns. Mothers with significant viremia are at a much higher risk of MTCT; therefore, treatments aimed at lowering HBV DNA levels during pregnancy may ultimately decrease global disease burden. The exact threshold for treatment remains controversial; however, most studies have accepted levels greater than 2 × 5 log10 IU/mL as significant viremia. We reviewed the most recent literature on antiviral efficacy, maternal and fetal safety, and viral resistance patterns when used for short-duration therapy in pregnancy...

BACKGROUND: Hemangiomas are unique endothelial cell tumors that involute spontaneously, which makes interpreting their response to therapies difficult. The objective of this work was to identify a potential biomarker in the urine of children with infantile hemangiomas that would facilitate testing new therapies. METHODS: A prospective longitudinal study in children with hemangiomas and age-matched healthy controls was performed to determine whether microRNA-126, which is highly abundant in fetal endothelial cells, was more abundant in the urine of affected children...

Chronic kidney disease (CKD) exacerbating vascular disease poses a major challenge to nephrology. Surgically placed vascular fistulas, as an aid to hemodialysis prior to kidney transplant, have extended many lives, while post-surgical restenosis closure of the fistula by smooth muscle cells affects many lives. When post-surgical restenosis is developed, palliative measures are almost always surgical: there are no effective drug treatments. In this study, we offer a testable hypothesis that effects of CKD on widely distributed vascular diseases and the phenomenon of fistula restenosis are both driven by the pathologic creation of non-dividing smooth muscle cells via asymmetric division of exponentially increasing metakaryotic stem cells...

More than 3 decades ago, a small group of physicians and other practitioners active in what they called "fetal treatment" authored an opinion piece outlining the current status and future challenges anticipated in the field. Many advances in maternal, neonatal, and perinatal care and diagnostic and therapeutic modalities have been made in the intervening years, yet a thoughtful reassessment of the basic tenets put forth in 1982 has not been published. The present effort will aim to provide a framework for contemporary redefinition of the field of fetal treatment, with a brief discussion of the necessary minimum expertise and systems base for the provision of different types of interventions for both the mother and fetus...

Ischemic heart disease remains one of the most prominent causes of mortalities worldwide with heart transplantation being the gold-standard treatment option. However, due to the major limitations associated with heart transplants, such as an inadequate supply and heart rejection, there remains a significant clinical need for a viable cardiac regenerative therapy to restore native myocardial function. Over the course of the previous several decades, researchers have made prominent advances in the field of cardiac regeneration with the creation of in vitro human pluripotent stem cell-derived cardiomyocyte tissue engineered constructs...

BACKGROUND: Fertility and pregnancy issues are of key importance for young breast cancer patients. Despite several advances in the field, there are still multiple unmet needs and barriers in discussing and dealing with these concerns. To address the significant challenges related to fertility and pregnancy issues, the PREgnancy and FERtility (PREFER) study was developed as a national comprehensive program aiming to optimize care and improve knowledge around these topics. METHODS: The PREFER study is a prospective cohort study conducted across several Italian institution affiliated with the Gruppo Italiano Mammella (GIM) group evaluating patterns of care and clinical outcomes of young breast cancer patients dealing with fertility and pregnancy issues...

REVIEW
Tara Krishnan, Anna L David
Fetal growth restriction (FGR) is a serious pregnancy complication affecting ∼8% of all pregnancies. There is no treatment to increase fetal growth in the uterus. Gene therapy presents a promising treatment strategy for FGR, with the use of adenoviral vectors encoding for proteins such as vascular endothelial growth factor (VEGF) and insulin-like growth factor demonstrating improvements in fetal growth, placental function, and neonatal outcome in preclinical studies. Safety assessments suggest no adverse risk to the mother or fetus for VEGF maternal gene therapy; a clinical trial is in development...

PURPOSE OF REVIEW: To provide new insights into pathogenesis, prevention and management of cardiac manifestations of neonatal lupus (cardiac neonatal lupus) and issues pertinent to all anti-SSA/Ro positive individuals of childbearing age. RECENT FINDINGS: Antibody specificity with high risk for cardiac neonatal lupus remains elusive, but high titers of Ro60, Ro52 or Ro52p200 antibodies appear to be required. Varying antibody specificities to the p200 region of Ro52 can induce first-degree block in a rodent model...

The concept of Regenerative Medicine combined with Cell based Therapy and Tissue Engineering represents the fourth pillar of healthcare and provides a promising approach for the treatment of serious diseases. Recently, cell based therapies are focused on the use of mesenchymal stem/stromal cells (MSCs). Human MSCs, that represent a mesoderm derived population of progenitors, are easily expanded in culture. They are capable to differentiate into osteoblasts, chondrocytes, and adipocytes and exhibit the potential to repair or regenerate damaged tissues...

Substance use among pregnant women is a major public health issue. Both prescription opioid use and illicit opioid abuse have increased dramatically in recent years. Prolonged in utero drug exposure may result in neonatal abstinence syndrome (NAS), an acute multisystemic clinical entity that occurs in the first days of life. This syndrome is caused by abrupt discontinuation of fetal exposure to licit or illicit drugs chronically consumed by the mother during pregnancy and transmitted to the fetus through the placenta...

Foetal microchimeric cells (FMCs) traffic into maternal circulation during pregnancy and persist for decades after delivery. Upon maternal injury, FMCs migrate to affected sites where they participate in tissue healing. However, the specific signals regulating the trafficking of FMCs to injury sites had to be identified. Here we report that, in mice, a subset of FMCs implicated in tissue repair displays CD11b(+) CD34(+) CD31(+) phenotype and highly express C-C chemokine receptor 2 (Ccr2). The Ccr2 ligand chemokine ligand 2 (Ccl2) enhances the recruitment of FMCs to maternal wounds where these cells transdifferentiate into endothelial cells and stimulate angiogenesis through Cxcl1 secretion...

OBJECTIVE: Pituitary surgeons frequently encounter female prolactinoma patients seeking treatment to restore fertility. Current medical guidelines recommend using dopamine agonist (DA) for this, but for fetal safety, DA should stop upon pregnancy confirmation. The probability that prolactinoma may grow during pregnancy makes this last recommendation imperfect. With the advances in endoscopic surgery, we queried the potential role for surgery in these infertile patients, who may be ambivalent about both stopping and continuing DA while pregnant...

Fetal ventriculomegaly (VM) refers to the enlargement of the cerebral ventricles in utero. It is associated with the postnatal diagnosis of hydrocephalus. VM is clinically diagnosed on ultrasound and is defined as an atrial diameter greater than 10 mm. Because of the anatomic detailed seen with advanced imaging, VM is often further characterized by fetal magnetic resonance imaging (MRI). Fetal VM is a heterogeneous condition with various etiologies and a wide range of neurodevelopmental outcomes. These outcomes are heavily dependent on the presence or absence of associated anomalies and the direct cause of the ventriculomegaly rather than on the absolute degree of VM...

Preeclampsia is a prevalent pregnancy hypertensive disease with both maternal and fetal morbidity and mortality. Emerging evidence indicates that global placental DNA hypomethylation is observed in patients with preeclampsia and is linked to altered gene expression and disease development. However, the molecular basis underlying placental epigenetic changes in preeclampsia remains unclear. Using 2 independent experimental models of preeclampsia, adenosine deaminase-deficient mice and a pathogenic autoantibody-induced mouse model of preeclampsia, we demonstrate that elevated placental adenosine not only induces hallmark features of preeclampsia but also causes placental DNA hypomethylation...

Even with the advances of conventional treatment techniques, the nervous system cancer prognosis is still not favorable to the patient which makes alternative therapies needed to be studied. Photodynamic therapy (PDT) is presented as a promising therapy, which employs a photosensitive (PS) agent, light wavelength suitable for the PS agent, and molecular oxygen, producing reactive oxygen species in order to induce cell death. The aim of this study is to observe the PDT action in gliosarcoma cell using a chlorin (Photodithazine, PDZ)...

INTRODUCTION: Extramedullary hematopoiesis (EMH) is the production of blood cell precursors outside the bone marrow that occur in various hematological diseases. In patients with thalassemia intermedia, ineffective erythropoiesis drives compensatory EMH in the liver, pancreas, pleura, spleen, ribs and spine. CASE PRESENTATION: We describe a patient with thalassemia intermedia who presented with acute neurological symptoms caused by paraspinal EMH, which responded well to combination therapy of steroid, hypertransfusion, laminectomy and excision of pseudotumor and hydroxyurea therapy to boost the formation of fetal haemoglobin...
