Zika virus infection histories in brain development.

An outbreak of births of microcephalic patients in Brazil motivated multiple studies on this incident. The data left no doubt that infection by Zika virus (ZIKV) was the cause, and that this virus promotes reduction in neuron numbers and neuronal death. Analysis of patients' characteristics revealed additional aspects of the pathology alongside the decrease in neuronal number.

Association of congenital Zika syndrome with dental alterations in children with microcephaly.

The effects of congenital Zika syndrome (CZS) on the tooth development of infected children are not well known. The aim of this study was to analyze the association of CZS with dental alterations in children with microcephaly seen at a referral hospital in Rio Grande do Norte, Brazil. The chronology and sequence of tooth eruption and the presence of dental alterations were evaluated by a single calibrated examiner (kappa > 0.

Factors Associated with Behavioral Disorders in Children with Congenital Zika Syndrome and Their Families-A Cross-Sectional Study.

The Zika virus was responsible for an outbreak between 2015 and 2016 in Brazil: an alarming public health problem of international relevance. The Congenital Zika Syndrome (CZS) is often associated with manifestations that are responsible for cognitive and motor development delays and behavioral disorders. Thus, we aimed to characterize the clinical-epidemiological and familial context of those children and to identify factors associated with the risk of behavioral disorders using the Survey of Well-Being of Young Children questionnaire (SWYC).

Microcephaly as a risk factor for dental alterations: A case-control study.

Objective: This study aimed to assess whether microcephaly is a risk factor for alterations in the chronology and sequence of tooth eruption and for developmental defects of enamel.

Matherials And Methods: In this case-control study, 81 children aged 30-36 months, including 40 normoreactive children and 41 with microcephaly, were submitted to oral clinical examination to determine the frequency of alterations in the chronology and sequence of tooth eruption and developmental enamel defects. The sample was matched for sex and age (1:1) and allocated to the case (presence of dental alterations) and control (absence of dental alterations) groups.

Association between brain morphology and electrophysiological features in Congenital Zika Virus Syndrome: A cross-sectional, observational study.

Background: Intrauterine infection with the Zika virus (ZIKV) has been connected to severe brain malformations, microcephaly, and abnormal electrophysiological activity.

Methods: We describe the interictal electroencephalographic (EEG) recordings of 47 children born with ZIKV-derived microcephaly. EEGs were recorded in the first year of life and correlated with brain morphology.

Assessment of child development in premature babies based on the ICF biopsychosocial model.

Background: The International Classification of Functionality (ICF) has been recommended to enable a broader and more holistic view of an individual's health condition. In addition, it works as an important reference for multiprofessional teams. In low-income countries, like Brazil, the attempts to systematize and incorporate the ICF model in health services has been a challenge.

Zika Virus Changes Methylation of Genes Involved in Immune Response and Neural Development in Brazilian Babies Born With Congenital Microcephaly.

The recent increase in babies born with brain and eye malformations in Brazil is associated with Zika virus (ZIKV) infection in utero. ZIKV alters host DNA methylation in vitro. Using genome-wide DNA methylation profiling we compared 18 babies born with congenital ZIKV microcephaly with 20 controls.

Chest circumference in full-term newborns: how can it be predicted?

Background: Although over the years a number of studies have used chest circumference (CC) as a sensitive tool to identify the health status of infants, a particularly important aspect for this population is the lack of data on normal values and prediction equations. In order to facilitate and validate the interpretation of CC data in newborn (NB), the aim was to study the relation between CC and other anthropometric variables and develop a predictive equation for CC in a population of full-term newborns.

Methods: Cross-sectional study, carried out with full-term infants.

Discordant congenital Zika syndrome twins show differential in vitro viral susceptibility of neural progenitor cells.

Congenital Zika syndrome (CZS) causes early brain development impairment by affecting neural progenitor cells (NPCs). Here, we analyze NPCs from three pairs of dizygotic twins discordant for CZS. We compare by RNA-Seq the NPCs derived from CZS-affected and CZS-unaffected twins.

A comparison between preterm and full-term infants' preference for faces.

Objective: Visual preference for faces at birth is the product of a multimodal sensory experience experienced by the fetus even during the gestational period. The ability to recognize faces allows an ecologically advantageous interaction with the social environment. However, perinatal events such as premature birth, may adversely affect the adequate development of this capacity.
