TPO and fetal growth restriction: Amariyo et al. reported that TPO and inflammatory cytokine levels in cord blood samples from SGA infants were significantly higher than in appropriate-for-gestational-age infants.20 They suggested that this increase was caused by a state of inflammation in the IUGR fetus.20 In the present study, the timing of blood sampling was later than in their study, and this discrepancy between study findings might be due to this difference in timing.
