In postmenopausal women, due to endocrine changes, there is an increase in oxidative stress (OS) that predisposes them to cardiovascular and metabolic alterations. Sixty-one percent of women in this stage require a primary therapeutic strategy to decrease OS. This study aimed to evaluate the effect of resveratrol and vitamin C on OS in postmenopausal women.

Pregnancy complicated by obesity represents an increased risk of unfavorable perinatal outcomes such as gestational diabetes mellitus (GDM), hypertensive disorders in pregnancy, preterm birth, and impaired fetal growth, among others. Obesity is associated with deficiencies of micronutrients, and pregnant women with obesity may have higher needs. The intrauterine environment in pregnancies complicated with obesity is characterized by inflammation and oxidative stress, where maternal nutrition and metabolic status have significant influence and are critical in maternal health and in fetal programming of health in the offspring later in life.

The maternal decidua is a transient and dynamic tissue that functions as an immunoprivileged matrix related to nutritional and endocrine processes. The function of decidual cells is key to the success of embryo implantation and the maintenance of pregnancy with a positive maternal-fetal outcome. Therefore, establishing a method to optimize the isolation of primary decidual cells is essential.

Article Synopsis
  • HIV infection affects around 1.7 million reproductive-aged women globally, and while PI-HAART has reduced vertical transmission from mother to child, concerns about its long-term effects on subcutaneous fat tissue in fetuses remain largely unexplored.
  • A study compared fetuses from HIV-pregnant women on PI-HAART to a control group and used 3D ultrasound to measure subcutaneous fat in the arms and thighs, finding significant fat reduction in those exposed to the treatment.
  • The results indicate that reduced subcutaneous fat is linked to lower newborn serum glucose levels, highlighting potential long-term health implications for infants exposed to PI-HAART and emphasizing the need for careful management of HIV-positive pregnant women.

Endothelial dysfunction (ED) in preeclampsia (PE) results from the convergence of oxidative stress, inflammation, and alterations in extracellular matrix components, affecting vascular tone and permeability. The molecular network leading to ED includes IL-8 and MMP-2. In vitro, IL-8 regulates the concentration and activity of MMP-2 in the trophoblast; this interaction has not been studied in endothelial cells during PE.
