Take high cholesterol off the list of health problems caused by low birthweight
Contrary to the "fetal origins" hypothesis and suggestions of a strong inverse relationship between birthweight and subsequent blood cholesterol levels, a recent study finds that 1-kg lower birthweight may be associated with at most about 2.0 mg/dL (0.05 mmol/L) higher total cholesterol later in life—an amount unlikely to have much impact on public health.

Researchers who reviewed 79 studies involving more than 74,000 people found overwhelming heterogeneity in the results, leading them to conclude that previously reported associations between birthweight and later cholesterol levels probably reflect inappropriately placed emphasis on particular study results and inappropriate adjustment for current weight and other confounding factors.

Cesarean delivery reduces mortality risk in preterm breech births
December 2nd 2024In a recent study, infants born very preterm or extremely preterm had reduced odds of mortality when cesarean delivery was chosen as the mode of delivery, without a notable increase in any morbidity risk.

Early preterm birth risk linked to low PlGF levels during pregnancy screening
November 20th 2024New research highlights that low levels of placental growth factor during mid-pregnancy screening can effectively predict early preterm birth, offering a potential tool to enhance maternal and infant health outcomes.

Major congenital malformations not linked to first trimester tetracycline use
November 20th 2024A large population-based study found that first-trimester tetracycline exposure does not elevate the risk of major congenital malformations, though specific risks for nervous system and eye anomalies warrant further research.
