Insights

Very preterm infants show significant growth deficits and developmental delays in their first two years. These infants also experience higher rates of hospital readmissions compared to full-term infants.

Area of Science:

  • Neonatology
  • Pediatric Development
  • Public Health

Background:

  • Infant outcomes vary significantly by region and country.
  • Preterm birth before 32 weeks gestation presents unique challenges.

Purpose of the Study:

  • To evaluate growth, developmental milestones, and post-discharge morbidity in very preterm infants in Switzerland.
  • Compare outcomes of very preterm infants with those born at term.

Main Methods:

  • National survey using questionnaires sent to parents of 456 survivors born in 1996.
  • 309 very preterm infants' data matched with 309 term-born control infants.
  • Data collected at corrected age of 24 months.

Main Results:

  • Very preterm infants had significantly lower weight, length, and head circumference.
  • Delayed milestones in spoon-feeding, cup drinking, and independent walking were observed.
  • 16% of very preterm infants were unable to walk independently by 18 months, increasing cerebral palsy risk.
  • 35% of very preterm infants required hospital readmission within 24 months, versus 20% of controls.

Conclusions:

  • National data quantify growth retardation, developmental delay, and health issues in preterm infants.
  • Early identification and intervention are crucial for improving long-term outcomes.

Teratogenicity01:07

Teratogenicity

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...

Pharmacokinetics in Pediatric Patients: Drug Metabolism

In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses a challenge in...

Introduction to Developmental Psychology

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...
Socioemotional Development during Infancy01:30

Socioemotional Development during Infancy

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.

Development of Human Microbiota01:30

Development of Human Microbiota

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
Development of the Oral Microbiota01:28

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
