Background: Advances in haemolytic disease of the fetus and newborn have led to numerous treatment options. We report practice variations in the management and outcomes of haemolytic disease of the fetus and newborn in at-risk pregnancies.

Methods: In this international, retrospective, observational cohort study, data from cases with moderate or severe haemolytic disease of the fetus and newborn were retrieved from 31 centres in 22 countries.

Gestational diabetes (GD) is a metabolic disorder characterized by glucose intolerance during pregnancy, significantly impacting maternal and fetal health. Its global prevalence is approximately 14%, with risk factors including obesity, family history of diabetes, advanced maternal age, and ethnicity, which are linked to cellular and molecular disruptions in glucose regulation and insulin resistance. GD is associated with short- and long-term complications for both the mother and the newborn.

Article Synopsis
  • - Preeclampsia (PE) is a complex pregnancy disorder characterized by high blood pressure and protein in urine, posing risks to mothers and their babies; its underlying mechanisms involve abnormal placentation and systemic responses.
  • - The condition is driven by inadequate placental development, leading to hypoxia and the release of anti-angiogenic factors, which cause endothelial dysfunction and increased inflammation; genetic factors also play a crucial role.
  • - Despite some promising therapeutic strategies targeting oxidative stress and inflammation, effective prevention and treatments for PE are still lacking, emphasizing the need for ongoing research in understanding and managing the disorder.

: Preterm birth (PTB) remains a significant global health challenge. Previous attempts to predict preterm birth in the first trimester using cervical length have been contradictory. The cervical consistency index (CCI) was introduced to quantify early cervical changes and has shown promise across various clinical scenarios in the mid-trimester, though testing in the first trimester is lacking.
