[Serum calcitonin in full-term infants]
Summary
Maternal and newborn calcium (Ca) and calcitonin (CT) levels were studied during labor and postpartum. Newborns showed higher initial calcitonin levels, which peaked at 12 hours, indicating a significant hormonal shift after birth.
Area of Science:
- Endocrinology
- Perinatal Physiology
Context:
- Investigates calcium and calcitonin dynamics during the critical transition from fetal to neonatal life.
- Examines maternal hormonal changes during labor and immediate postpartum.
Purpose:
- To determine serum calcium (Ca) and calcitonin (CT) secretion patterns in mothers during labor and their newborns in the early hours of life.
- To compare maternal and neonatal Ca and CT levels.
Summary:
- Mean serum Ca levels decreased post-birth.
- Serum CT levels were higher in cord blood than maternal blood.
- Neonatal CT levels peaked at 12 hours postpartum, remaining elevated for 48 hours.
Impact:
- Provides insights into the hormonal regulation of calcium homeostasis in newborns.
- Highlights the role of calcitonin in the perinatal period.
- Contributes to understanding physiological adaptations after birth.
