Prenatal and early postnatal fatty acid status and neurodevelopmental outcome Abstract The present review addresses the effect of pre- and postnatal supplementation of nutrition with long-chain polyunsaturated fatty acids (LCPUFA) on neurodevelopmental outcome. The few studies which addressed the effect of prenatal LCPUFA status or prenatal LCPUFA supplementation suggest that a better prenatal arachidonic acid (AA) and doxosahexaenoic acid (DHA) status might be related to a better neurodevelopmental outcome until at least 18 months of age. A review of the few randomized controlled trials on formula supplementation with LCPUFA in preterm infants did not provide evidence for a significant beneficial effect of LCPUFA on developmental outcome. A review of the trials on formula supplementation with LCPUFA in term infants revealed that supplementation with LCPUFA, in particularly supplementation with ≥0.30% DHA, has a beneficial effect on neurodevelopmental outcome until 4 months. The studies could not demonstrate a consistent positive effect beyond that age. It was concluded that the relatively subtle effects of LCPUFA supplementation on neurodevelopmental outcome do not only depend on dosage but also on the gestational period during which the nutritional components are supplied: supplementation prior to term seems to have more effect than that after term.

Effect of oxygen tension on bacteria-stimulated cytokine production by fetal membranes Abstract
Aim: Tissue culture studies indicate that bacterial products stimulate the production of proinflammatory cytokines by reproductive tissues. However, most of these studies have been performed under room air conditions, supplemented with 5% CO2 . In this study, we tested whether O2 tension affects bacteria-stimulated cytokine production by extra-placental fetal membranes.
Methods: Cultures of full-thickness membranes, isolated choriodecidua, and isolated amnion were exposed to bacteria and incubated under 21% (room air) or 5% O2 for 18 h. Cytokine concentrations in conditioned medium was quantified by immunoassay.
Results: Culture under 5% O2 increased production of interleukin (IL)-1β and tumor necrosis factor (TNF)-α, but reduced IL-10 and IL-6 production by full membranes. Isolated choriodecidua responded to 5% O2 with increased IL-1β production and reduced IL-6 production, but had no effect on TNF-α and IL-10 production was not detected. No effect of O2 tension on IL-1β or IL-6 production by isolated amnion was detected, however, Escherichia coli -stimulated IL-10, TNF-α and IL-8 production was enhanced by culture under 5% O2 .
Conclusions: Increased oxygen tension reduces the pro-inflammatory responsiveness of cell cultures to E. coli and promotes an anti-inflammatory cytokine profile. Differential effects of O2 tension on choriodecidua and amnion suggests a network of paracrine factors that regulate cytokine levels in response to changes in O2 tension.

Effect of bisphenol-A (BPA) on placental biomarkers for inflammation, neurodevelopment and oxidative stress Abstract
Background
Bisphenol-A (BPA) is a widespread pollutant whose effects on pregnant women are poorly understood. Therefore, we investigated the effects of BPA on basal and bacteria-stimulated production of proinflammatory cytokines [interleukin (IL)-1β, tumor necrosis factor-α (TNF-α) and IL-6], anti-inflammatory mediators [soluble glycoprotein 130 (sgp) 130, heme oxidase-1 (HO-1) and IL-10] and biomarkers for neurodevelopment [brain-derived neurotrophic factor (BDNF)], and oxidative stress [8-isoprostane (8-IsoP)] by the placenta.
Methods
Placental explant cultures were treated with BPA (0–10,000 nM) in the presence or absence of 107 colony-forming unit (CFU)/mL heat-killed Escherichia coli for 24 h. Biomarker concentrations in conditioned medium were quantified by the enzyme-linked immunosorbent assay (ELISA).
Results
Under basal conditions, IL-1β and IL-6 production was enhanced by BPA in a dose-dependent manner. Sgp130, a soluble receptor that reduces IL-6 bioactivity, was suppressed by BPA at 1000–10,000 nM. BPA also enhanced BDNF production at 1000 and 10,000 nM, and 8-IsoP expression at 10 and 100 nM. For bacteria-treated cultures, BPA increased IL-6 production at 100 nM and reduced sgp130 at 1000 nM but had no effect on IL-1β, TNF-α, BDNF, HO-1, 8-IsoP or IL-10 production.
Conclusion
BPA may increase placental inflammation by promoting IL-1β and IL-6 but inhibiting sgp130. It may also disrupt oxidative balance and neurodevelopment by increasing 8-IsoP and BDNF production.

Effects of tributyltin on placental cytokine production Abstract
Objective
Tributyltin (TBT) is a persistent pollutant but its effects on placental function are poorly understood as are its possible interactions with infection. We hypothesized that TBT alters the production of sex hormones and biomarkers for inflammation and neurodevelopment in an infection-dependent manner.
Methods
Placental explant cultures were treated with 0–5000 nM TBT in the presence and absence of Escherichia coli . A conditioned medium was harvested and concentrations of steroids (progesterone, P4 ; testosterone, T and estradiol, E2 ) as well as biomarkers of inflammation [interleukin (IL)-1β (IL-1β), tumor necrosis factor (TNF-α), IL-10, IL-6, soluble glycoprotein 130 (sgp-130) and heme oxygenase-1 (HO-1)], oxidative stress [8-iso-prostaglandin (8-IsoP)] and neurodevelopment [brain-derived neurotrophic factor (BDNF)] were quantified.
Results
TBT increased P4 slightly but had little or no effect on T or E2 production. IL-1β, IL-6, sgp-130, IL-10 and 8-IsoP production was enhanced by TBT. P4 and IL-6 production was also enhanced by TBT for bacteria-stimulated cultures but TBT significantly inhibited bacteria-induced IL-1β and sgp-130 production. High doses of TBT also inhibited BDNF production.
Conclusions
TBT increases P4 but has minimal effect on downstream steroids. It enhances the production of inflammatory biomarkers such as IL-1β, TNF-α, IL-10 and IL-6. Inhibition of sgp-130 by TBT suggests that TBT may increase bioactive IL-6 production which has been associated with adverse neurodevelopmental outcomes. Reduced expression of BDNF also supports this possibility.
