Ischemic stroke, the main reason for severe disabilities in the world, is associated with a high incidence of sensorimotor and cognitive dysfunction. In this study, we use the middle cerebral artery occlusion/reperfusion (MCAO/R) model in rats and oxygen glucose deprivation/reoxygenation (OGD/R) model in fetal rat primary cortical neurons to investigate whether and how S-oxiracetam (S-ORC) protect brain injury from ischemic stroke. The results revealed that S-ORC reduced brain infarct size and lessened neurological dysfunction after stroke...

BACKGROUND: Congenital Zika virus (ZIKV) infection can be detected in both the presence and absence of microcephaly, and manifests as a number of signs and symptoms detected clinically and by neuroimaging. However, to date, qualitative and quantitative measures for the purpose of diagnosis and prognosis are limited. OBJECTIVES: Main objectives of this study conducted on fetuses and infants with confirmed congenital ZIKV infection and detected brain abnormalities are: 1) To assess the prevalence of microcephaly and the frequency of the anomalies including a detailed description based on ultrasound and magnetic resonance imaging (MRI) in fetuses and ultrasound, MRI and computed tomography imaging postnatally; 2) To provide quantitative measures of fetal and infant brain findings by MRI using volumetric analyses and diffusion weighted imaging (DWI); 3) To obtain additional information from placental and fetal histopathological assessments and postnatal clinical evaluations...

Zika virus (ZIKV) is a mosquito-borne flavivirus that emerged as a global threat following the most recent outbreak in Brazil in 2015. ZIKV infection of pregnant women is associated with fetal abnormalities such as microcephaly, and infection of adults can lead to Guillain-Barré syndrome, an autoimmune disease characterized by neurological deficits. Although there are currently licensed vaccines for other flaviviruses, there remains an urgent need for preventative vaccines against ZIKV infection. Herein we describe the current efforts to accelerate the development of ZIKV vaccines using various platforms, including live attenuated virus, inactivated virus, DNA and RNA, viral vectors, and in silico-predicted immunogenic viral epitopes...

Human cytomegalovirus (HCMV) is the most common congenitally transmitted pathogen worldwide, impacting an estimated 1 million newborns annually. Congenital HCMV (cCMV) infection is a major global contributor to long-term neurologic deficits, including deafness, microcephaly, neurodevelopmental delay, as well as fetal loss and occasional infant mortality. Accordingly, a maternal vaccine to prevent cCMV continues to be a top public health priority. Nevertheless, we remain without a licensed vaccine. Maternal immunity provides partial protection, as the risk of vertical HCMV transmission from chronically infected mothers is reduced compared to settings in which the mother is newly infected during pregnancy...

Human cytomegalovirus (HCMV) infection is the primary viral cause of congenital abnormalities and mental retardation in newborns. The HCMV UL141‑encoded glycoprotein has been previously revealed to inhibit the cell‑surface expression of cluster of differentiation (CD)155, CD122, tumor necrosis factor‑related apoptosis‑inducing ligand death (TRAIL)‑receptor 1 (R1) and TRAIL‑receptor 2 (R2), thus protecting virally‑infected cells by allowing them to escape natural killer cell‑mediated cytotoxicity...

Background: To assess maternal and fetal outcome of women and newborns who received chemotherapy during pregnancy to treat Hodgkin lymphoma (HL)in early stages (IA, IIA), we performed a retrospective analysis of a cohort of 44 pregnant women with HL and early stages, diagnosed and treated between 1988 to 2013, at a tertiary reference cancer center. Methods: We analyzed data on HL characteristics and treatment, with a particular attention to maternal and fetal complications; in children, we performed a longer follow-up to detect any anomaly in physical development, scholar performance, psychological, cardiac, neurological function, and intelligence tests...

Ionizing radiation at high doses early in life may cause neurodevelopmental problems. Possible effects of lower doses are, however, controversial. We use carefully collected exposure data for Norway following the Chernobyl accident in April 1986 combined with population-based registries to assess long-term effects of fetal exposure on neurodevelopmental outcomes. Radiation doses were estimated for each Norwegian municipality for each calendar month from May 1986 to April 1989. We established a cohort of all Norwegian pregnancies during the three-year period of radiation measurement and compared them with appropriate unexposed groups...

Fetal neurology is evolving as an area of great interest in prenatal diagnosis and fetal medicine. The identification and diagnosis of brain damage prenatally has been a great challenge in obstetrics for many years. Investigations of fetal behavior in comparison with morphological studies led to the conclusion that fetal behavioral patterns directly reflect developmental and maturational processes of the fetal central nervous system (CNS). Four-dimensional (4D) ultrasound has greatly improved the assessment of the quality of the fetal spontaneous movements, and enabled a better evaluation of fetal behavior...

BACKGROUND: Of the 4 million neonatal deaths worldwide yearly, 98% occur in low and middle-income countries. Effective resuscitation reduces mortality and morbidity but long-term outcomes in resource-limited settings are poorly described. This study reports on newborn neurological outcomes following resuscitation at birth in a resource-limited setting where intensive newborn care including intubation is unavailable. METHODS: Retrospective analysis of births records from 2008 to 2015 at Shoklo Malaria Research Unit (SMRU) on the Thailand-Myanmar border...

Silent white matter changes (WMCs) on brain imaging are common in individuals with sickle cell disease (SCD) and are associated with cognitive deficits in children. We investigated the factors predictive of WMCs in adults with homozygous SCD and no history of neurological conditions. Patients were recruited from a cohort of adults with homozygous SCD followed up at an adult sickle cell referral center for which steady-state measurements of biological parameters and magnetic resonance imaging scans of the brain were available...

Zika virus (ZIKV) is an arthropod-borne arbovirus from the family Flaviviridae, which has been recently confirmed to cause severe neurological abnormalities (such as microcephaly, brain parenchymal calcification, hydrocephalus, and malformations of cortical development) in the infected fetuses. The Placenta plays a multifold role in prenatally acquired ZIKV infection. It serves as a port of virus transmission to the fetus, and also can be directly affected by ZIKV leading to a diminished fetal blood supply or a disrupted/changed biological mediators' synthesis...

Zika virus (ZIKV) is an emerging healthcare threat. The presence of the mosquito Aedes species across South and Central America in combination with complementary climates have incited an epidemic of locally transmitted cases of ZIKV infection in Brazil. As one of the most significant current public health concerns in the Americas, ZIKV epidemic has been a cause of alarm due to its known and unknown complications. At this point, there has been a clear association between ZIKV infection and severe clinical manifestations in both adults and neonates, including but not limited to neurological deficits such as Guillain-Barré syndrome (GBS) and microcephaly, respectively...

Zika virus (ZIKV) is a flavivirus that is primarily transmitted by Aedes aegypti, the mosquito vector also important in the transmission of the flaviviruses responsible for dengue fever, yellow fever and chikungunya. Due to occurrence in the same geographic regions, serological cross-reactivity, and similar, albeit often less severe clinical manifestations as dengue and chikungunya infections, ZIKV infection likely went undetected and/or misdiagnosed for many years. ZIKV is somewhat unique among flaviviruses in its ability to also be transmitted via sexual contact, non-sexual body fluids and perinatally...

Preterm birth interrupts the precise process of fetal maturation, forcing critical neurologic growth to continue within the Neonatal Intensive Care Unit (NICU). Concern for the impact of the NICU experience on the developing brain led to a unit-based Quality Improvement (QI) project to promote best outcomes for our graduates. The objective was to implement a standard of care for neonatal neuroprotection in a large urban tertiary center. A multidisciplinary committee researched and developed the Neonatal Neuroprotective Best Practice Guidelines to identify optimal interventions, as well as provide physiologic rationales to reinforce importance of these practices...

Intrauterine hypoxia is one of the most common stressors in fetuses, which can lead to abnormal brain development and permanent neurological deficits in adulthood. Neurological disorder excitotoxicity induced by hypoxia or ischemia may involve N-methyl-D-aspartate receptors (NMDARs), which are known to participate in the maturation and plasticity of developmental neurons. Inhibition of NMDARs has been reported to improve neurological outcomes in traumatic brain injuries and Alzheimer's disease. Here, we investigated if antenatal blockade of NMDARs induced by memantine could alleviate neurodevelopmental brain damage and long-term cognitive deficits in intrauterine hypoxia rats...

Brain injury in premature infants, especially periventricular leukomalacia, is an important cause of neurological disabilities. Inflammation contributes to the development of perinatal brain injury, but the essential mediators leading to brain injury in early life remain largely unknown. Neonates have reduced capacity for mounting conventional αβT-cell responses. However γδT-cells are already functionally competent during early development and are important in early life immunity. We investigated the potential contribution of γδT-cells to preterm brain injury by using postmortem brains from human preterm infants with periventricular leukomalacia and two animal models of preterm brain injury-the hypoxic-ischemic mouse model and a fetal sheep asphyxia model...

BACKGROUND: Previous reports from the Management of Myelomeningocele Study (MOMS) demonstrated that prenatal repair of myelomeningocele reduces hindbrain herniation, the need for cerebrospinal fluid shunting, and improves motor function in children with myelomeningocele. The trial was stopped for efficacy after 183 patients had been randomized, but 30-month outcomes were only available at the time of initial publication in 134 mother-child dyads. Data from the complete cohort for the 30-month outcomes are presented here...

Although the causes of intrauterine growth restriction (IUGR) have been intensively investigated, important information is still lacking about the role of the placenta as a link from adverse maternal environment to adverse pregnancy outcomes of IUGR and preterm birth. IUGR is associated with an increased risk of cardiovascular, metabolic, and neurological diseases later in life. Determination of the most important pathways that regulate transplacental transport systems is necessary for identifying marker genes as diagnostic tools and for developing drugs that target the molecular pathways...
