Neonatal seizures are the most frequent type of neurological disorder and those newborn babies that experience seizures carry an increased risk of epileptogenesis and other long-term morbidities. The newly generated dentate granule cells (DGCs) integrate functionally into the mature hippocampal network by continuously forming connections with their targets but this process of adult neurogenesis can be influenced by seizures. When compared to adult seizures, neonatal seizures may exert different effects on neurogenesis due to the high resistance of the newborn's neurons to cell death combined with the inherent high sensitivity to seizures in the immature brain...

Prenatal inorganic arsenic (iAs) exposure influences the expression of critical genes and proteins associated with adverse outcomes in newborns, in part through epigenetic mediators. The doses at which these genomic and epigenomic changes occur have yet to be evaluated in the context of dose-response modeling. The goal of the present study was to estimate iAs doses that correspond to changes in transcriptomic, proteomic, epigenomic, and integrated multi-omic signatures in human cord blood through benchmark dose (BMD) modeling...

BACKGROUND: In most low and middle-income countries vital events registration for births and child deaths is poor, with reporting of pregnancy outcomes highly inadequate or non-existent. Health and Demographic Surveillance System (HDSS) sites and periodic population-based household-level surveys can be used to identify pregnancies and retrospectively capture pregnancy outcomes to provide data for decision making. However, little is known about the performance of different methods in identifying pregnancy and pregnancy outcomes, yet this is critical in assessing improvements in reducing maternal and newborn mortality and stillbirths...

PURPOSE: The Stanford University Network for the Diagnosis of Retinopathy of Prematurity (SUNDROP) initiative-an ongoing telemedicine-based initiative for in-hospital screening of high-risk infants for treatment-warranted ROP (TW-ROP)-has been shown to be a safe, reliable, and cost-effective supplement to the efforts of ROP specialists. We utilized data collected in the SUNDROP initiative to determine demographic (birth weight, sex, multiplicity), weight gain, and ocular imaging (media haze, peripapillary atrophy, fundus pigmentation) predictors of TW-ROP...

Introduction It has been established that underweight women with low gestational weight gain (GWG) are at a higher risk of having Small for Gestational Age (SGA) newborns. However, the association remains poorly studied in Middle Eastern societies exhibiting different ethnic groups, genetic predisposing factors along with differences in nutritional food intake during pregnancy. The aim of this study is to assess the risk of having a SGA newborn among underweight and normal weight BMI women while studying the role of GWG in this association...

BACKGROUND: Very low birth weight (VLBW) neonates (<1,500 g) comprise approximately 1% of liveborn infants in Poland. Patent ductus arteriosus (PDA) is a common complication of prematurity. This study aimed to determine how many VLBW neonates treated in the participating units needed a surgical correction of PDA, and to evaluate the incidence of various types of post-operative infections, and their microbiology. METHODS: Observational study in five neonatology departments by the Polish Neonatology Surveillance Network, involving 2039 VLBW newborns of whom 103 (5...

INTRODUCTION: Improving maternal and newborn survival remains major aspirations for many countries in the Global South. Slum settlements, a result of rapid urbanisation in many developing countries including Kenya, exhibit high levels of maternal and neonatal mortality. There are limited referral mechanisms for sick neonates and their mothers from the community to healthcare facilities with ability to provide adequate care. In this study, we specifically plan to develop and assess the added value of having community health volunteers (CHVs) use smartphones to identify and track mothers and children in a bid to reduce pregnancy-related complications and newborn deaths in the urban slums of Kamukunji subcounty in Nairobi, Kenya...

Recent studies using animal models indicated that the members of the amyloid precursor protein (APP) gene family are important for the formation, maintenance, and plasticity of synapses. Despite this, the specific role of the APP homologs APLP1 and APLP2 within the CNS and PNS is still poorly understood. In contrast to the subtle phenotypes of single mutants, double knockout mice (DKO) lacking APP/APLP2 or APLP1/APLP2 die within the first day after birth. Whereas APP/APLP2-DKO mice show severe deficits of neuromuscular morphology and transmission, the underlying cause of lethality of APLP1/APLP2-DKO mice remains unclear...

The consumption of psychoactive drugs during pregnancy can have deleterious effects on newborns. It remains unclear whether early-life exposure to caffeine, the most widely consumed psychoactive substance, alters brain development. We hypothesized that maternal caffeine ingestion during pregnancy and the early postnatal period in mice affects the construction and activity of cortical networks in offspring. To test this hypothesis, we focused on primary visual cortex (V1) as a model neocortical region. In a study design mimicking the daily consumption of approximately three cups of coffee during pregnancy in humans, caffeine was added to the drinking water of female mice and their offspring were compared to control offspring...

Sleep deprivation during pregnancy is an emerging concern, as it can adversely affect the development of the offspring brain. This study was conducted to evaluate the effects of deprivation of rapid eye movement (REM) sleep during the third term of pregnancy on the sleep-wake profiles of neonates in the Wistar rat model. Sleep-wake patterns were assessed through electrophysiological measures and behavioural observations during postnatal days 1-21 on pups born to REM sleep-deprived dams and control rats. Pups of REM sleep-deprived dams had active sleep that was not only markedly higher in percentage during all the days studied, but also had reduced latency during later postnatal days 15-21...

Despite major improvements in reducing childhood mortality worldwide, over 5 million pregnancies per year end in stillbirths or neonatal deaths. The vast majority of these deaths occur in low- and middle-income countries. Many of these deaths are preventable with readily available evidence-based care practices. This review focuses on educational programs developed to reduce preventable deaths in newborn infants in low- and middle-income countries, including Essential Newborn Care and Helping Babies Breathe, a simplified version of the Neonatal Resuscitation Program...

One of the first "tools" used for systematically evaluating successful newborn transitional physiology at birth was the Apgar Score, devised by Virginia Apgar in 1953. This objective assessment tool allowed clinicians to immediately gauge the relative success of a newborn infant making the transition from the in utero liquid immersive environment to the ex utero gas environment in the delivery room during the first minutes after birth. The scoring system, although eponymous, is generally summarized as an acronym based on Appearance, Pulse, Grimace, Activity, and Respiration, criteria evaluated and scored at 1 and 5 min after birth...

Prenatal psychoactive substance exposure has significant impact on neonatal health and child development and the development of reliable biomarkers is critical. Meconium presents several advantages for detecting prenatal exposure to psychoactive substances, as it is easy to collect and provides a broad time frame of exposure (third trimester). The aim of our study was to compare the prevalence of alcohol, tobacco and/or cannabis use during the third trimester of pregnancy (using maternal self-reports) with the results of meconium testing of their metabolites in newborns (cotinine, ethyl-glucuronide (EtG) and cannabinoid metabolites)...
