Insights

Preterm infants often do not receive adequate vitamin A in the first two weeks of life. Early initiation of intravenous vitamin A and consideration of oral supplementation may be necessary.

Area of Science:

  • Neonatal Nutrition
  • Pediatric Gastroenterology
  • Vitamin Metabolism

Background:

  • Preterm infants exhibit lower vitamin A stores at birth than term infants.
  • Current vitamin A intake recommendations for preterm infants range from 700-1500 IU/kg/day.
  • Optimal early nutrition is critical for preterm infant development.

Purpose of the Study:

  • To assess vitamin A intake adequacy in preterm infants during the first four weeks of life.
  • To identify feeding patterns associated with sufficient vitamin A intake in this population.

Main Methods:

  • Retrospective case note review conducted at a UK tertiary neonatal unit.
  • Study included 36 preterm infants (median gestation 30 weeks).
  • Evaluated mean daily total vitamin A intake over the first four weeks of life.

Main Results:

  • Only 11% of infants met recommended vitamin A intake in the first two weeks.
  • Vitamin A adequacy was not influenced by gestational age or feeding pattern.
  • Intravenous lipid with fat-soluble vitamins was initiated on day 2 per policy.

Conclusions:

  • Current intravenous vitamin A supplementation guidelines for preterm infants need revision.
  • Early initiation of intravenous lipids with vitamins is recommended.
  • Consider early oral vitamin A for enterally fed preterm infants.

Drug Dosing: Infants and Children01:29

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...
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...

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,...

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...
Development of Immunocompetence01:22

Development of Immunocompetence

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...

Pharmacokinetics in Pediatric Patients: Drug Excretion

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...
