The Impact of Inflammatory Cytokines on Recurrent Pregnancy Loss: A Preliminary Investigation.

Recurrent pregnancy loss (RPL), defined as two or more consecutive miscarriages before 20 weeks of gestation, affects 1-2% of couples worldwide. Pro-inflammatory cytokines, such as TNF-α, IL-1β and IL-6 play critical roles in early pregnancy, while anti-inflammatory cytokines like TGF-β and IL-10 promote immune tolerance to prevent harmful inflammatory responses that play important role in placental and fetal development. This aim of the study is to analyse the levels of inflammatory cytokines in blood serum from RPL patients and healthy women (control).

Solid lipid nanoparticles (SLNs) have gained interest as drug delivery carriers due to their efficient cellular internalization and increased therapeutic effect of the loaded drug, with minimal side effects. Although recently several studies have shown the possibility to administer SLNs during pregnancy to vehicle mRNA to the placenta, data about the effect of premating exposure to SLNs on pregnancy outcome are scant. Considering that assumption of drug-delivering nanocarriers in reproductive age may potentially affect women's reproductive health, the aim of the present study was to evaluate whether repeated oral administration of SLNs to female mice prior to mating would influence key pregnancy outcomes.

Prenatal exposure to the toxic metal inorganic arsenic (iAs) is associated with adverse pregnancy and fetal growth outcomes. These adverse outcomes are tied to physiological disruptions in the placenta. While iAs co-occurs in the environment with other metals such as manganese (Mn), there is a gap in the knowledge of the effects of metal-mixtures on the placenta.

Mitochondria play a central role in nutrient metabolism, besides being responsible for the production of adenosine triphosphate (ATP), the main source of cellular energy. However, the ATP production process is associated with the generation of reactive oxygen species (ROS), which excessive accumulation can cause mitochondrial dysfunction. This dysfunction, in turn, causes the accumulation of fatty acids in the adipose tissue, triggering a local inflammatory process that can evolve into systemic inflammation.

Background: Recurrent pregnancy loss (RPL) often stems from a hypercoagulable state that exacerbates conditions such as antiphospholipid syndrome (APS) and thrombophilia, leading to early placental issues. Although treatments such as low-molecular-weight heparin (LMWH) and low-dose aspirin (LDA) are used, outcomes vary. This study proposes using first-trimester Doppler ultrasound - specifically, uterine radial artery resistance index (URa-RI) at 8 weeks and uterine artery pulsatility index (Ut-PI) with pre-diastolic notching (Ut-notch) at 11-13 weeks - to better predict successful pregnancies and reduce risks of adverse outcomes.
