Insights

Preterm infants appropriate for gestational age (AGA) with higher birth measurements experienced greater growth declines during hospitalization. However, breastfeeding initiated in-hospital helped recovery by 2 months corrected age (CA).

Area of Science:

  • Neonatal research
  • Pediatric growth studies
  • Infant nutrition

Background:

  • Premature infants often face growth challenges.
  • Early breastfeeding is encouraged for infant health.
  • Growth patterns in preterm infants require monitoring.

Purpose of the Study:

  • To assess growth and breastfeeding in preterm AGA infants up to 18 months corrected age (CA).
  • To evaluate the impact of in-hospital breastfeeding initiation on infant growth.
  • To identify risks for inadequate growth in hospitalized preterm infants.

Main Methods:

  • Retrospective, descriptive, and comparative study of 127 preterm AGA infants.
  • Data collected via medical chart review and maternal questionnaires.
  • Growth parameters (weight, length, head circumference SDS) tracked up to 18 months CA.

Main Results:

  • Weight, length, and head circumference SDS decreased during hospitalization ( -0.9, -0.3, -0.5 respectively).
  • Infants with higher birth SDS showed greater negative growth changes pre-discharge.
  • Growth increments by 2 months CA compensated for or exceeded initial losses.

Conclusions:

  • Higher birth SDS in preterm AGA infants indicates a risk for poor growth during hospitalization.
  • In-hospital breastfeeding initiation may support growth recovery post-discharge.
  • Continued monitoring of growth is crucial for preterm infants.

Nature and Nurture01:10

Nature and Nurture

Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience, such as differences...
Regression Toward the Mean01:52

Regression Toward the Mean

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when researchers try to extrapolate results...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...

Changes in the Appendicular Skeleton with Age

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
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...

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...
