Special Issue Information

Dear Colleagues,

A second volume of ‘Oxidative Stress during Pregnancy and Childhood’ is being proposed in order to offer neonatologists and pediatricians with a modern and complete view of the various problems and aspects of oxidative stress in neonatology, currently among the most complex and advanced fields of pediatrics.

The volume will be dedicated to the epidemiology of neonatal mortality and morbidity and to the conditions responsible for oxidative stress prenatal and neonatal risk. A section will be devoted to new antioxidant drugs and strategies for efficient modern neonatal and infant care.

Particular attention will be paid to brain-oriented care and current availability of laboratory facilities and instrumentation for the early identification of perinatal abnormalities. Conditions jeopardizing oxidative stress and fetal health such as diabetes, maternal drug abuse and smoking will be discussed.

Moreover, the concept of fetal programming, relating the origins of adult diseases to an altered redox environment, has been established, with evidence in this field now extensively.  

Oxidative stress plays a role in generating and favoring structural placental alterations that may cause adverse neonatal outcomes. For this purpose, the cellular and molecular mediators associated with complications of pregnancy will be examined as these are essential for the development of successful intervention and prevention strategies. Different oxidative stress-related diseases of the neonate, involving lungs, heart, gastrointestinal tract, blood, immune system, endocrine system, and kidneys, will be expounded up. Fetal and neonatal infections and neurological abnormalities will also be discussed in depth.

Also, the neurodevelopmental alterations that may be found in children who have experienced any form of oxidative stress during the fetal and postnatal period will be discussed and examined.

The next challenging goal will be to define as-yet-unrecognized biologic therapeutic targets and link oxidative stress biomarkers to relevant standard indices and long-term outcomes.

We invite authors to submit the latest research results or review articles to this Issue, which will bring together current research related to oxidative stress in pregnancy and childhood and discuss the effects of antioxidant therapy.

Readers will be able to use this volume alongside the summaries, tables, and accurately selected guidelines or recommendations accompanying it to supply quick references and instant solutions to the concerned neonatologists and pediatricians during their daily practice.

Maternal obesity has been associated with short- and long-term risks of pregnancy-perinatal adverse events, possibly due to alterations of placental mitochondrial bioenergetics. However, several detrimental mechanisms occurring in the placentas of women with obesity still need to be clarified. Here, we analyzed placental mitochondrial features and oxidative environment of 46 pregnancies in relation to pre-pregnancy BMI. Seventeen Caucasian normal-weight (NW) and twenty-nine women who were obese (OB) were enrolled. The protein expression of mitochondrial CypD and electron transfer chain complexes (C) I–V were measured, as well as ATP production and oxygen consumption rates (OCRs). The protein levels of the pro/anti-oxidant enzymes TXNIP, SOD2, and PON2 were also analyzed. Despite no differences in CypD expression, OCRs were significantly lower in OB vs. NW women. Accordingly, ATP synthase (CV) levels and ATP content were decreased in OB women, positively correlating with placental efficiency, suggesting a link between ATP deficiency and placental dysfunction. SOD2 expression negatively correlated with maternal BMI, indicating a possible impairment of antioxidant defenses with increasing BMI. These changes were worsened in 10 OB women presenting with gestational diabetes mellitus. Overall, these results suggest alterations of placental bioenergetics in pregnancies of women with obesity, possibly leading to placental dysfunction and altered fetal development and programming.
