Prenatal hypoxia and placental oxidative stress: linkages to developmental origins of cardiovascular disease.

Published: October 2017

Intrauterine growth restriction (IUGR, a pregnancy complication where the fetus does not reach its genetic growth potential) is a leading cause of fetal morbidity and mortality with a significant impact on population health. IUGR is associated with gestational hypoxia; which can lead to placental oxidative stress and fetal programming of cardiovascular disease. Mitochondria are a major source of placental oxidative stress and may provide a therapeutic target to mitigate the detrimental effects of placental oxidative stress on pregnancy outcomes. A nanoparticle-mediated delivery of a mitochondrial antioxidant to the placenta is a potential novel approach that may avoid unwanted off-target effects on the developing offspring.

Preeclampsia (PE) is a serious complication of pregnancy linked to endothelial dysfunction and an imbalance in the gut microbiota. While (AKK) has shown promise in alleviating PE symptoms, the use of live bacteria raises safety concerns. This study explored the potential of pasteurized (pAKK) as a safer alternative for treating PE, focusing on its effects on endothelial function and metabolic regulation.

The present study aimed to investigate and compare oxidative stress biomarkers and antioxidant enzyme activity in the serum of women at risk of developing preeclampsia (PE) to prevent adverse pregnancy outcomes through early intervention. Changes in soluble fms-like tyrosine kinase-1 (sFlt-1) and placental growth factor (PlGF) levels were measured between 11 and 13 gestational weeks (gw.) before the onset of preeclampsia and its associated complications.

Background: Pregnancy has been identified as a risk factor for severe COVID-19, leading to maternal and neonatal complications. The safety and effects of the SARS-CoV-2 vaccination during pregnancy, particularly on placental function and oxidative stress (OxS), remain underexplored. We investigated the impact of vaccination on third-trimester placental antioxidant defense markers.

Background And Aim: Pregnancy after the age of 35 is correlated with an increased risk of impaired placentation and the development of pregnancy-associated complications. Changes in uterine redox balance seem to play a role in these settings. In this work, we hypothesized that local redox dysregulation impacts the placenta metabolic profile.
