Modeling Encephalopathy of Prematurity Using Prenatal Hypoxia-ischemia with Intra-amniotic Lipopolysaccharide in Rats
Published on: November 20, 2015
Summary
High infant mortality historically, especially in the days after birth, may be linked to early deliveries caused by strenuous domestic work. This hypothesis is supported by seasonal patterns in neonatal mortality.
Area of Science:
- Historical demography
- Perinatal epidemiology
- Sociomedical history
Context:
- Infant mortality historically showed a peak in the days following birth.
- Modern premature infants face risks like hypothermia.
- Neonatal mortality and stillbirth rates were exceptionally high until the late 19th century.
Purpose:
- To hypothesize the causes of high historical neonatal mortality and stillbirth rates.
- To explore the link between domestic labor and early delivery.
- To investigate the role of early delivery in historical infant mortality.
Summary:
- The study proposes that heavy domestic work led to early deliveries, causing high neonatal mortality and stillbirths until the late 19th century.
- Historical infant mortality data reveals a concentration of deaths in the early neonatal period.
- Seasonal variations in neonatal mortality support the hypothesis linking delivery timing to maternal workload.
Impact:
- Provides a novel perspective on historical infant mortality causes.
- Suggests a socioeconomic determinant for perinatal health outcomes.
- Highlights the potential impact of physical labor on pregnancy and birth outcomes.

01:07Teratogenicity
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...
01:14Fetal Circulation
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

01:28Development 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,...
