Modeling Encephalopathy of Prematurity Using Prenatal Hypoxia-ischemia with Intra-amniotic Lipopolysaccharide in Rats
Published on: November 20, 2015
[Extreme prematurity--medical and social problem].
Summary
Survival rates for extremely preterm newborns improved due to advances like assisted ventilation and surfactant therapy. However, this progress has not reduced long-term health issues or disabilities in these vulnerable infants.
Area of Science:
- Neonatal Medicine
- Perinatology
- Public Health
Context:
- Improved survival rates for extremely preterm infants (born at 25 or fewer weeks gestation) since the early 1990s.
- Advances in assisted ventilation and surfactant therapy have contributed to better outcomes.
- World Health Organization (WHO) redefined the perinatal period starting at 22 weeks gestation in 1993.
Purpose:
- To examine the impact of improved survival rates on morbidity in extremely preterm newborns.
- To discuss the medical, social, and ethical challenges associated with managing infants at the threshold of viability.
- To address the complexities of decisions regarding elective delivery and intensive care for preterm infants.
Summary:
- Survival rates for extremely preterm infants have increased due to medical interventions like assisted ventilation and surfactant therapy.
- Despite improved survival, there has not been a corresponding decrease in morbidity or long-term disabilities.
- The increasing risk of disability or death with decreasing gestational age presents significant ethical and management dilemmas.
Impact:
- Highlights the critical need for strategies to reduce morbidity in extremely preterm infants, not just improve survival.
- Raises important questions about the ethical considerations of intensive care and delivery decisions for borderline viable neonates.
- Informs clinical practice and policy regarding the management of high-risk pregnancies and preterm births.

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...
Inborn Errors of Metabolism
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...
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,...
