Teratogenicity01:07

Teratogenicity

3.0K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Socioemotional Development during Infancy

180
Socio-emotional development in infancy is primarily shaped by early emotional responses and social connections, with temperament playing a central role. Temperament refers to the consistent patterns in an individual's emotional and behavioral responses, observable even in infancy. By examining temperament, researchers can better understand an infant's unique ways of interacting with the world, influencing subsequent personality and socio-emotional growth.

Neurulation01:30

Neurulation

43.0K
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the...

The Nativist Approach01:21

The Nativist Approach

179
The nativist approach to infant cognitive development proposes that infants are born with inherent knowledge structures that allow them to interpret the world almost immediately. This perspective contrasts with earlier developmental theories, such as those proposed by Jean Piaget, which emphasized a more gradual acquisition of cognitive abilities through interaction with the environment. One key concept in this approach is object permanence — the understanding that objects continue to...

Inborn Errors of Metabolism01:20

Inborn Errors of Metabolism

294
Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...

Introduction to Developmental Psychology01:27

Introduction to Developmental Psychology

677
Developmental psychology explores the changes and continuities in human abilities throughout life, encompassing physical, cognitive, linguistic, and social dimensions. Human development is not restricted to growth, but includes aspects of decline, particularly in physical abilities as individuals age. Developmental psychologists seek to understand how people change as they age and how their mental and social skills evolve.Developmental MilestonesA key concept in developmental psychology is...

Area of Science:

  • Neonatalogy and Developmental Pediatrics
  • Public Health and Epidemiology

Background:

  • The EPIPAGE-2 study followed a cohort of extremely preterm infants.
  • Understanding long-term outcomes for premature infants is crucial for clinical practice and public health.
  • Socio-economic status (SES) is a known factor influencing child development and participation in studies.

Purpose of the Study:

  • To assess the neurodevelopmental outcomes at 5.5 years of age for children born prematurely (24-34 weeks' gestational age).
  • To investigate the impact of gestational age and socio-economic status on the outcomes of preterm infants.
  • To identify specific challenges and needs for follow-up programs for preterm infants, particularly those from lower SES backgrounds.

Main Methods:

  • Longitudinal cohort study of premature infants born between 24 and 34 weeks' gestational age.
  • Neurodevelopmental assessments at 5.5 years of corrected age.
  • Statistical analysis accounting for socio-economic status and imputation of missing data.

Main Results:

  • Survival rates increased with higher gestational age.
  • Among survivors born at 24-26 weeks' gestational age, 75% had no or mild impairment at 5.5 years.
  • Mild cognitive impairment and school problems were common across all gestational age groups.
  • Lower socio-economic status was associated with increased risk of developmental impairment.

Conclusions:

  • Gestational age and socio-economic status are critical determinants of neurodevelopmental outcomes in preterm infants.
  • Mild cognitive impairments and school difficulties are prevalent in this population.
  • Targeted follow-up programs and interventions are needed, especially for preterm infants from lower socio-economic backgrounds.
