- The current study aimed to characterize changes in EEG-related measures after noxious stimuli in neonates, and to assess their potential utility as measures of pain and/or discomfort during neonatal intensive care.Seventy-two healthy term infants were investigated: Twenty-eight had a non skin-breaking pin-prick on the heel, randomized to receive either oral glucose (n=16) or water (n=12) before the stimulus. 21 infants were studied during a venous blood sample from the dorsum of the hand, 23 infants during a capillary heel stick. Behavioral pain responses were assessed with the Premature Infant Pain Profile (PIPP) scale. The stimulus evoked a significant increase in higher frequency components (10-30Hz) which also correlated to behavioral measures. The frontotemporal localization of the increased activity with frequency bands similar to electromuscular artifacts and the relation to behavioral measures confirmed that this activity corresponds to an increase in muscle tone. There was no change in frontal EEG asymmetry in any of the groups. The present results indicate that responses in cortical activity recorded by EEG are not useful for clinical assessment of infants' responses to noxious stimuli.

- Background: Foetal inflammation is associated with an increased risk of brain damage in preterm infants whereas IGF-I is essential for cerebral development and exhibits anti-apoptotic properties. Aim: To assess levels of IGF-I and IGF binding proteins at very preterm birth and to evaluate their relationship with foetal pro-inflammation and cerebral damage. Methods: Levels of IGF-I, IGF binding protein 3 (IGFBP-3), high- (hp) and low-phosphorylated (lp) IGFBP-1 in cord blood and neonatal blood at 72 h after delivery were analysed in relation to levels of cytokines and cerebral damage as detected by ultrasound in 74 inborn infants [mean gestational age (GA) 27.1 weeks]. Evaluation was performed separately according to birth weight for GA. Results: In cord blood of infants appropriate for gestational age (AGA) higher levels of IL-6 and IL-8 were associated with lower IGF-I (r = -0.38, p = 0.008 and r = -0.36, p = 0.014). Higher levels of IL-6, IL-8 and TNF-alpha were associated with both higher levels of lpIGFBP-1 (r = 0.54, p < 0.001, r = 0.50, p < 0.001 and r = 0.13, p = 0.012, respectively) and hpIGFBP-1 (r = 0.55, p < 0.001, r = 0.45, p = 0.002 and r = 0.32, p = 0.026, respectively). Infants with intraventricular haemorrhage grade III (n = 5) had higher levels of lp/hpIGFBP-1 in cord blood (p = 0.001 and 0.002, respectively). Conclusion: Pro-inflammation at birth is associated with changes in the IGF-system. This may be of importance for development of brain damage in preterm infants.

- Preterm birth carries a risk for impaired developmental outcome. We have previously described an association between increased levels of pro-inflammatory cytokines during the first 72 postnatal hours and cerebral damage as detected by ultrasound in a cohort of 74 very preterm infants. Sixty-seven of 71 surviving children with a mean (SD) GA of 27.1 (2.0) weeks were examined at 2 years corrected age with a standardized neurological examination and with Bayley Scales of Infant Development. We hypothesized that pro-inflammatory cytokine concentrations at or shortly after birth would be associated with an adverse developmental outcome. Increased concentrations of TNF-alpha in cord blood OR (95% CI) 3.3 (1.1-10.2), p=0.013 and at 6 h 7.8 (0.9-71.8), p=0.015 and of IL-6 in cord blood 1.7 (1.0-2.9), p=0.048 were associated with psychomotor developmental index <85. Increased concentrations of TNF-alpha in cord blood OR (95% CI) 3.6 (1.002-12.8), p=0.044 and of IL-8 in cord blood 3.5 (1.2-10.6), p=0.023 were associated with cerebral palsy. Associations of TNF-alpha and IL-8 in cord blood with the respective outcome measures remained significant after adjustment for other clinical variables. Pro-inflammation at birth is associated with impaired functional outcome at 2 years of corrected age in children with very preterm birth.
