Paracetamol, its metabolites, and their transfer between maternal circulation and fetal brain in mono- and combination therapies.

Department of Neuroscience, School of Translational Medicine, Monash University, Melbourne, VIC, 3004, Australia.
Background: Due to its availability and perceived safety, paracetamol is recommended even during pregnancy and for neonates. It is used frequently alone or in combination with other drugs required for the treatment of various chronic conditions. The aim of this study was to investigate potential effects of drug interactions on paracetamol metabolism and its placental transfer and entry into the developing brain.

The 2023-2024 updates on teratovigilance, with a focus on antiseizure medications, highlight several key points. American medical societies have revised their recommendations: maintaining effective seizure control is essential for both maternal and fetal health; lamotrigine, levetiracetam, and oxcarbazepine are preferred first-line treatments, whereas valproic acid and topiramate should be avoided if possible. In March 2024, an update on topiramate indicated an increased risk of neurodevelopmental disorders with prenatal exposure.

Autism spectrum disorder (ASD) is a prevalent neurodevelopmental condition affecting a substantial number of children globally, characterized by diverse aetiologies, including genetic and environmental factors. Emerging research suggests that neurovascular dysregulation during development could significantly contribute to autism. This review synthesizes the potential role of vascular abnormalities in the pathogenesis of ASD and explores insights from studies on valproic acid (VPA) exposure during neural tube development.

To investigate the promoting effect of extracellular vesicles derived from myocardial cells (CM-EVs) on the reprogramming of cardiac fibroblasts (CFs) into cardiomyocyte-like cells (iCMs) and their therapeutic effect on myocardial infarction (MI) in rats. Cell experiments: The differential adhesion method was used to obtain Sprague Dawley (SD) suckling rat CFs and cardiomyocytes (CMs), while the ultracentrifugation method was used to obtain CM-EVs. Transmission electron microscopy and nanoparticle tracking technology were used to analyze and determine the morphology and particle size of CM-EVs.

There are substantial differences in the characteristics of males and females with an autism spectrum disorder (ASD), yet there is little knowledge surrounding the mechanistic underpinnings of these differences. The valproic acid (VPA) rodent model is based upon the human fetal valproate spectrum disorder, which is associated with increased risk of developing ASD. This model, which displays significant social, learning, and memory alterations, has therefore been widely used to further our understanding of specific biological features of ASD.
