Objective: To provide a comprehensive analysis of the temporal structure of sucking in full-term neonates.
Design: Descriptive study.
Setting: Newborn nursery in a city teaching institution.
Patients/participants: Fifty-six full-term infants with a mean birth weight of 3,128±370 g completed sucking assessments on the first and second day of life.
Methods: A 5-minute sucking assessment was completed on the first and second day of life. Instruments included an Infant Nutritive Sucking Apparatus and the Anderson Behavioral Assessment Scale.
Results: The number of sucks (p<.001), intersuck width (p=.008) and interburst width (p<.05) were significantly different between the first and second day of life. On the second day of life the infants generated significantly more sucks, a decrease in interburst width and a decrease in intersuck width. There was a significant increase in the presence of an alert behavioral state from the first to second sucking assessment (p<.01). In addition, with a more alert infant state there was an increased time spent bursting (p<.001).
Conclusion: Our results show that sucking analysis is sensitive to infant status and suggest that the development of sucking methodology can be considered as a useful clinical tool to assess the normal developmental course of sucking patterns.

Characterization of language abilities and semantic networks in very preterm children at school-age.

It has been widely assessed that very preterm children (<32 weeks gestational age) present language and memory impairments compared with full-term children. However, differences in their underlying semantic memory structure have not been studied yet. Nevertheless, the way concepts are learned and organized across development relates to children's capacities in retrieving and using information later.

Background: Immunoglobulin A (IgA) plays a crucial role in the maturation the neonatal mucosal barrier. The accumulation of IgA antibody-secreting cells (ASCs) in the lactating mammary gland facilitates the secretion of IgA antibodies into milk, which are then passively to the suckling newborn, providing transient immune protection against gastrointestinal pathogens. Physiologically, full-term infants are unable to produce IgA, required for mucosal barrier maturation for at least 10 days after birth.

Background: Since the implementation of China's comprehensive two-child policy, the prevalence of long interpregnancy intervals (IPI) and advanced maternal age has increased. However, previous studies in China have mostly focused on the relationship between short IPIs and adverse perinatal outcomes, while neglecting maternal age as a potential confounder.
Methods: We conducted a retrospective cohort study of 23,899 pregnant women who delivered between January 1, 2017 and December 31, 2019 at Chengdu Women's and Children's Central Hospital and West China Second Hospital of Sichuan University.
Low birth weight and chronic kidney disease with progression to kidney failure in children.

Institute of Population Health Sciences, National Health Research Institutes, Miaoli County, Taiwan.
Background And Hypothesis: It is unclear if low birth weight (LBW), preterm birth and small for gestational age (SGA) could synergistically cause chronic kidney disease (CKD) and end-stage kidney disease (ESKD). This cohort study was conducted to examine their individual and combined impacts on the development of CKD and ESKD in childhood.
Methods: From the Taiwan Maternal and Child Health Database, we identified 1 477 128 newborns born between January 1, 2009, and December 31, 2016.
Haemophilia Infants Gross Motor Development: Comparisons With Full-Term and Preterm Infants of the Same Nationality.
Haemophilia

Haemophilia Centre/Haemostasis and Thrombosis Unit, "Aghia Sophia" Children's Hospital, Athens, Greece.
Introduction: Infants with haemophilia, due to parental overprotection, have difficulty developing their full motor repertoire of typical gross motor development. It is of great clinical importance to evaluate the motor development of these infants with a standardized assessment tool.
Aim: To study the gross motor development in infants with haemophilia, using the Alberta Infant Motor Scale (AIMS) and compare it with full-term (FT) and preterm infants (PT).
