The ability to separate pitch from other spectral sound features, such as timbre, is an important prerequisite of veridical auditory perception underlying speech acquisition and music cognition. The current study investigated whether or not newborn infants generalize pitch across different timbres. Perceived resonator size is an aspect of timbre that informs the listener about the size of the sound source, a cue that may be important already at birth. Therefore, detection of infrequent pitch changes was tested by recording event-related brain potentials in healthy newborn infants to frequent standard and infrequent pitch-deviant sounds while the perceived resonator size of all sounds was randomly varied. The elicitation of an early negative and a later positive discriminative response by deviant sounds demonstrated that the neonate auditory system represents pitch separately from timbre, thus showing advanced pitch processing capabilities.

Objective: Aim: To determine the influence of maternal and neonatal variants of the eNOS (G894T, rs1799983) and IL1B (C3953T, rs1143634) genes and their intergenic interactions on the development of HIE in newborns.
Patients And Methods: Materials and Methods: The study included a cohort of 105 newborns and their 99 mothers. Determination of variants of the genes eNOS (G894T, rs1799983) and IL1B (C3953T, rs1143634) was carried out for the patients of study groups.

Objective: To apply the Toronto Childhood Cancer Staging Guidelines (TG) and Estimate the Observed Survival Probabilities for Pediatric Patients with Leukemia and Lymphoma.
Methods: Staging at diagnosis was conducted according to tier 2 of the TG. The study cohort included patients aged 0 -19 years from the Population-Based Cancer Registry (PBCR) of Mato Grosso, diagnosed with leukemia and lymphoma between 2008 and 2017, with follow-up until December 31, 2022.

Gastrointestinal Defects and Immunodeficiency Syndrome-1 (GIDID-1), caused by abnormalities in TTC7A, is an autosomal recessive disorder characterized by multiple gastrointestinal malformations and immune deficiencies, often accompanied by inflammatory bowel disease (IBD). This condition typically results in poor treatment outcomes and is usually fatal in early infancy. This paper examined the genetic abnormalities and clinical features of GIDID by analyzing data from three children and one fetus with gastrointestinal dysfunction and immune deficiency associated with TTC7A abnormalities at our hospital, and reviewed reported cases worldwide.

Background: Myelomeningocele (MMC) is the most common type of congenital spinal malformation, typically requiring surgical intervention. While prenatal repair is increasingly favored, postnatal repair remains the standard in many settings. This study aims to evaluate the antibiotics prescribed to neonates with MMC and their correlation with central nervous system (CNS) infection rates following postnatal surgical repair.
