Human induced pluripotent stem (iPS) cell-derived neurons and astrocytes are attractive cellular tools for nervous system disease modeling and drug screening. Optimal utilization of these tools requires differentiation protocols that efficiently generate functional cell phenotypes in vitro. As nervous system function is dependent on networked neuronal activity involving both neuronal and astrocytic synaptic functions, we examined astrocyte effects on the functional maturation of neurons from human iPS cell-derived neural stem cells (NSCs)...

Angelica V Glover, Tracy A Manuck
Despite considerable effort aimed at decreasing the incidence of spontaneous preterm birth, it remains the leading cause of perinatal morbidity and mortality. Screening strategies are imperfect. Approaches used to identify women considered by historical factors to be low risk for preterm delivery (generally considered to be women with singleton pregnancies without a history of a previous preterm birth) as well as those at high risk for preterm birth (those with a previous preterm birth, short cervix, or multiple gestation) continue to evolve...

Animal models are valuable tools for screening novel therapies for patients who suffer from epilepsy. However, a wide array of models are necessary to cover the diversity of human epilepsies. In humans, neonatal hypoxia (or hypoxia-ischemia) is one of the most common causes of epilepsy early in life. Hypoxia-induced seizures (HS) during the neonatal period can also lead to spontaneous seizures in adulthood. This phenomenon, i.e., early-life hypoxia leading to adult epilepsy - is also seen in experimental models, including rats...

OBJECTIVES: We sought to determine the screening performance of a low fetal cerebroplacental ratio (a marker of fetal adaptation to suboptimal growth) and maternal placental growth factor levels, respectively, both in isolation and in combination, for the detection of cesarean section for intrapartum fetal compromise and serious composite neonatal outcome. METHODS: A prospective cohort study was performed on low risk women with uncomplicated singleton pregnancies from 36 weeks to delivery...

Vitamin D (VD) has exhibited immunomodulatory role in the pathogenesis of preeclampsia. We hypothesize VD potentiate nifedipine treatment for preeclampsia by shortened the time to control blood pressure and prolong time before subsequent hypertensive crisis. We conduct a randomized trial of 683 primigravid women with preeclampsia, who were assigned to different treatment groups, either nifedipine+placebo or nifedipine+VD orally, by random after screening. Primary endpoints include time to control hypertension and time before another hypertensive crisis...

Humans use spatial representations to structure abstract concepts [1]. One of the most well-known examples is the "mental number line"-the propensity to imagine numbers oriented in space [2, 3]. Human infants [4, 5], children [6, 7], adults [8], and nonhuman animals [9, 10] associate small numbers with the left side of space and large numbers with the right. In humans, cultural artifacts, such as the direction of reading and writing, modulate the directionality of this representation, with right-to-left reading cultures associating small numbers with right and large numbers with left [11], whereas the opposite association permeates left-to-right reading cultures [8]...

Blood represents an easily accessible human tissue for numerous research and clinical applications, including surrogate roles for biomarkers of other tissues. Dried blood spots (DBS) are space- and cost-efficient storage forms of blood while stably retaining many of its chemical constituents. Consequently, neonatal DBS are routinely collected in many countries, and their biobanks represent gold mines for research. However, the utility of DBS is restricted by the limited amount and quality of extractable biomolecules (including DNA), especially for genome-wide profiling...

BACKGROUND: In 2012, there was an estimated 78 million new cases of gonorrhoea globally. Untreated infection may lead to reproductive and neonatal morbidity and facilitate HIV transmission. Diagnosis and treatment are a priority for control and prevention, yet use of point-of-care tests (POCTs) for Neisseria gonorrhoeae (NG) is limited. OBJECTIVES: To review the performance and operational characteristics of NG POCTs for diagnosis of urogenital gonorrhoea. METHODS: We compiled and synthesised findings from two separate systematic reviews which included evaluations published until August 2015...

Sickle cell disease is the genetic disorder most commonly detected with state-mandated newborn screening. Women with sickle cell disease struggle with psychosocial, emotional, and physical challenges throughout their lives. Pregnancy for women with sickle cell disease brings greater risk for maternal and fetal morbidity and mortality and increased likelihood of hospitalization for complications, including sickle cell pain crisis. Chronic maternal opioid use for pain can place newborns at risk for neonatal abstinence syndrome...

With an onus on safety in the potential use of porcine islet cells as a treatment for diabetes, the use of animals lacking exogenous pathogens is clearly important and multilevel screening strategies have been presented on testing animals and the product. In this study, we wished to investigate whether islet cells indeed harboured the same viral pathogens of concern in the source animal. PMBC and islet cells from both adult and neonatal source animals were directly compared and tested for PCMV, PLHV, PCV2, PPV and HEV using both molecular and serological assays...

BACKGROUND: Several approaches exist to screen neonates for congenital cytomegalovirus (CMV) infection. We here describe a new method using cellulose pads for urine collection and its evaluation in an experimental and a clinical setting. METHODS: We systematically tested the effect of storage duration of the pads after exposure to CMV-positive urine, meconium contamination and specimen handling on the CMV load and the detection rate. Further, the method was tested in clinical practice in a cohort of 500 neonates...

The newborn screening paradigm of testing all newborns in the United States for treatable conditions within the first few hours of birth has proven to be a remarkable success story in the realm of public health by reducing neonatal and childhood morbidity and mortality. The Newborn Screening Saves Lives Act of 2007 and its successor, the Reauthorization Act of 2014, legislated the establishment of a Department of Health and Human Services Advisory Committee to make recommendations around newborn screening and a methodology to establish and add new conditions to a Recommended Uniform Screening Panel (RUSP) which currently includes 34 core conditions...

Introduction: Inborn errors of metabolism (IEM) represent an important public health problem due to current diagnosis and treatment limitations, poor life quality of affected patients, and consequent untimely child death. In contrast to classical methods, tandem mass spectrometry (MS/MS) has allowed simultaneous evaluation of multiple metabolites associated with IEM offering higher sensitivity, low false positive rates and high throughput. Aims: Determine concentration levels for amino acids and acylcarnitines in blood of newborns from Colombia, to establish reference values for further use in diagnosis of IEM...

BACKGROUND: Treatment intensity scores can predict mortality and estimate resource use. They may therefore be of interest for essential neonatal care in low resource settings where neonatal mortality remains high. We sought to systematically review neonatal treatment intensity scores to (1) assess the level of evidence on predictive performance in predicting clinical outcomes and estimating resource utilisation and (2) assess the applicability of the identified models to decision making for neonatal care in low resource settings...

The underlying pathophysiology of liver dysfunction in urea cycle disorders (UCDs) is still largely elusive. There is some evidence that the accumulation of urea cycle (UC) intermediates are toxic for hepatocyte mitochondria. It is possible that liver injury is directly caused by the toxicity of ammonia. The rarity of UCDs, the lack of checking of iron level in these patients, superficial knowledge of UC and an underestimation of the metabolic role of fumaric acid, are the main reasons that are responsible for the incomprehension of the mechanism of liver injury in patients suffering from UCDs...

Hyperbilirubinemia is a common problem during the neonatal period and is the most common reason for readmission after early hospital discharge of the healthy near term and term infants. This early discharge policy along with limited follow-up facilities in developing countries and inadequate communication between physicians and parents necessitates a prognostic test to predict hyperbilirubinemia in these newborns; for early and effective management and prevention of potential complication before it occurred...
