Summary
Late preterm infants (34-36 weeks) face significantly higher morbidity and mortality rates compared to full-term infants. This study highlights the increased risks and need for revised care protocols for these near-term babies.
Area of Science:
- Neonatalogy
- Perinatology
- Public Health
Context:
- Rising prematurity rates, particularly late preterm births (34-36 weeks), present a growing concern.
- Late preterm infants exhibit higher morbidity than term infants, often underestimated.
- This study analyzes trends and outcomes in late preterm vs. term infants.
Purpose:
- To determine the incidence of prematurity in the institution.
- To compare morbidity and mortality rates between late preterm and term infants.
- To analyze morbidity across gestational ages from 34 to 42 weeks.
Summary:
- Prematurity increased from 3.9% to 9.8%, driven by late preterm births (79%).
- Late preterm infants showed significantly higher mortality (5/1000 vs. 1.1/1000) and morbidity (Neonatal Unit admission, respiratory issues, jaundice, hypoglycemia, etc.).
- Morbidity decreased with increasing gestational age, with lowest rates from 39 weeks.
Impact:
- Findings underscore the substantial risks associated with late preterm birth.
- Revising care guidelines and protocols for late preterm infants is crucial.
- Long-term psychomotor development monitoring and increased obstetric awareness are recommended.

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...
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: Drug Distribution
Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight, compared...
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...
