Neural circuits undergo massive refinements during postnatal development. In the developing cerebellum, the climbing fiber (CF) to Purkinje cell (PC) network is drastically reshaped by eliminating early-formed redundant CF to PC synapses. To investigate the impact of CF network refinement on PC population activity during postnatal development, we monitored spontaneous CF responses in neighboring PCs and the activity of populations of nearby CF terminals using in vivo two-photon calcium imaging. Population activity is highly synchronized in newborn mice, and the degree of synchrony gradually declines during the first postnatal week in PCs and, to a lesser extent, in CF terminals...

OBJECTIVE: The new epidemic of Zika virus infection raises grave concerns, especially with the increasingly-recognized link between emerging cases of microcephaly and this infectious disease. Besides small cranial dimensions, there are striking morphologic anomalies in the fetal brain. Key anomalies include cortical developmental malformations and a peculiar distribution of pathologic calcifications. These potentially indicate a new pattern of congenital central nervous system infection...

OBJECTIVE: Evaluate the interaction between maternal age and education level in neonatal mortality, as well as investigate the temporal evolution of neonatal mortality in each stratum formed by the combination of these two risk factors. METHODS: A nonconcurrent cohort study, resulting from a probabilistic relationship between the Mortality Information System and the Live Birth Information System. To investigate the risk of neonatal death we performed a logistic regression, with an odds ratio estimate for the combined variable of maternal education and age, as well as the evaluation of additive and multiplicative interaction...

BACKGROUND: Premature birth occurs when nephrogenesis is incomplete and has been linked to increased renal pathologies in the adult. Metabolic factors complicating preterm birth may have additional consequences for kidney development. Here, we evaluated the effects of prematurity and hyperglycemia on nephrogenesis in premature baboons when compared to term animals. METHODS: Baboons were delivered prematurely (67% gestation; n=9) or at term (n=7) and survived 2-4 weeks...

BACKGROUND: Excess vernix caseosa produced by the fetal skin appears as particles suspended in the amniotic fluid in late gestation, is swallowed by the fetus and is found throughout the newborn GI tract as the first organisms are arriving to colonize the gut. Lipid rich vernix contains an unusually high 29% branched chain fatty acid (BCFA). BCFA reduce the incidence of necrotizing enterocolitis in an animal model, recently found predominantly in the sn-2 position of human milk triacylglycerols...

Premature infants tend to lose heat quickly. This loss can be aggravated when they have received an invasive procedure involving a venous puncture. This research uses crossover design by conducting 2 intervention tests to compare 2 different treatments on the same sample. This research involved 2 groups with 18 premature infants in each. The process of data analysis used a statistical independent t test. Interventions conducted in an open incubator showed a p value of .001 which statistically related to heat loss in premature infants...

Newborns are at risk of developing hypothermia due to the instability of their thermoregulation systems and inability to adjust to changes in ambient temperature. This risk increases during hospitalization. Education is a strategy to improve nurses' understanding of the prevention of hypothermia in newborns in the hospital. This study aimed to analyze the impact of education about preventing heat loss on nurses' knowledge and behavior in preventing hypothermia in newborns. The study design was a quasi-experiment with one group pre-test-post-test and a total sample of 21 neonatal nurses who were selected using the consecutive sampling method...

Performance-based financing (PBF) is assumed to improve health care delivery by motivating health workers to enhance their work performance. However, the exact motivational mechanisms through which PBF is assumed to produce such changes are poorly understood to date. Although PBF is increasingly recognized as a complex health systems intervention, its motivational effect for individual health workers is still often reduced to financial 'carrots and sticks' in the literature and discourse. Aiming to contribute to the development of a more comprehensive understanding of the motivational mechanisms, we explored how PBF impacted health worker motivation in the context of the Malawian Results-based Financing for Maternal and Newborn Health (RBF4MNH) Initiative...

Neisseria subflava belongs to Neisseriaceae family, is considered a comensal specie, however in certain host, mainly inmunosuppresed patientes and children, the literature has documented invasive infections. We present a case of a bacteriemia due to N. subflava in a newborn, treated with cefotaxime with good outcome. In newborns, the most common Neisseria bacteria to cause invasive infections are N. meningitidis, with highly fatal clinical course and N. gonorrhoeae which compromise the eye, oftalmia neonatorum, with uncommon invasive infections...

Background: Brain-derived neurotrophic factor (BDNF) is a type of growth factor that promotes growth and survival of neurons. Fetal exposure to opiates can lead to postnatal withdrawal syndrome, which is referred as neonatal abstinence syndrome (NAS). Preclinical and clinical studies have shown an association between opiates exposure and alteration in BDNF expression in the brain and serum levels in adult. However, to date, there are no data available on the effects of opiate exposure on BDNF levels in infant who are exposed to opiates in utero and whether BDNF level may correlate with the severity of NAS...

Introduction: Though the human fetus is exposed to placentally derived human chorionic gonadotropin (hCG) throughout gestation, the role of hCG on the fetal brain is unknown. Review of the available literature appears to indicate that groups of women with higher mean levels of hCG during pregnancy tend to have offspring with lower cerebral palsy (CP) risk. Given that newborn cerebral injury often precedes the development of CP, we aimed to determine whether hCG may protect against the neurodegenerative effects of neonatal brain injury...

Background: Indications for endoscopic retrograde cholangiopancreatography (ERCP) in children differ from adults. Paucity of data and concerns about potential lower effectiveness and more side effects limit its use even in high volume centers. We retrospectively analyzed indications, success rates, limitations, and side effects of ERCPs in children <18 years. Methods: From January 2012 to March 2015, 54 ERCPs were performed in 31 children (median age 11 (0-17) years; median weight 22 (3...

Background: Utilization of antenatal care (ANC) services has increased over the past two decades. Continued gains in maternal and newborn health will require an understanding of both access and quality of ANC services. We linked health facility and household survey data to examine the quality of service provision for five ANC interventions across health facilities in sub-Saharan Africa. Methods: Using data from 20 nationally representative health facility assessments - the Service Provision Assessment (SPA) and the Service Availability and Readiness Assessment (SARA), we estimated facility level readiness to deliver five ANC interventions: tetanus toxoid vaccine for pregnant women, intermittent preventive treatment for malaria in pregnancy (IPTp), syphilis detection and treatment in pregnancy, iron supplementation and hypertensive disease case management...

Preterm infants present an immature neurobehavioral profile at birth, even in absence of severe brain injuries and perinatal complications. As such, they require a long-lasting hospitalization in the Neonatal Intensive Care Unit (NICU), which is thought to grant at-risk newborns' survival, but still entails a number of physical, painful, and socio-emotional stressors. Hence, preterm birth and NICU stay represent an early adverse experience, which has been linked to detrimental consequences for neurological, neuro-endocrinal, behavioral, and socio-emotional development, as well as to disease later in life...
