Possible reasons for change are: (1) advancing maturation of central nervous system; and (2) increasing experience with noxious procedures during hospital stay. Sixteen preterm infants were recruited, with a postmenstrual age (PMA) ranging between 29 and 36 weeks. Newborns were assessed during a heel-prick procedure, once a week for at least 3 consecutive times. Multichannel near-infrared spectroscopy was used to detect cortical activation, by measuring increase in cortical oxy-haemoglobin (HbO2). Parietal, temporal, and posterior frontal areas were monitored bilaterally. By regression analysis, we studied the effect of (1) increasing PMA and (2) increasing number of heel pricks, on the magnitude of cortical activation. We observed a bilateral nociceptive event-related activation of the posterior frontal cortex, mainly contralateral to the side pricked. Additionally, we found a significant positive effect of PMA, as HbO2 progressively increased in the posterior frontal cortex (P &lt; 0.001), bilaterally, over time. Conversely, the degree of cortical activation decreased as the number of noxious events increased (P &lt; 0.002). We conclude the following: (1) Preterm newborns showed a significant activation of the posterior frontal cortex in association with noxious stimuli; (2) Cortical activation was progressively greater with increasing PMA; (3) There was an inverse relationship between cortical activation and the number of heel pricks. We speculate that such findings may be due to both endogenous cortical maturation and experience-dependent neuroplasticity of the developing brain (eg, synaptogenesis, synaptic pruning).&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">9</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/27152689?dopt=Abstract</style></custom1></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Bembich, Stefano</style></author><author><style face="normal" font="default" size="100%">Travan, Laura</style></author><author><style face="normal" font="default" size="100%">Cont, Gabriele</style></author><author><style face="normal" font="default" size="100%">Bua, Jenny</style></author><author><style face="normal" font="default" size="100%">Strajn, Tamara</style></author><author><style face="normal" font="default" size="100%">Demarini, Sergio</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Cerebral oxygenation with different nasal continuous positive airway pressure levels in preterm infants.</style></title><secondary-title><style face="normal" font="default" size="100%">Arch Dis Child Fetal Neonatal Ed</style></secondary-title><alt-title><style face="normal" font="default" size="100%">Arch.

Baseline HbO2, HbTot and HbO2/HbTot values were initially collected with NCPAP at 5 cm H2O and then compared with values obtained with NCPAP levels at both 3 and 8 cm H2O.&lt;/p&gt;&lt;p&gt;&lt;b&gt;RESULTS: &lt;/b&gt;Compared with 5 cm H2O, cerebral HbO2, HbTot and HbO2/HbTot remained unchanged both after increasing (to 8 cm H2O) and decreasing (to 3 cm H2O) the NCPAP level. This result was observed both in regional areas (24 sites) and in the overall monitored area (frontal and parietal cortex). Compared with 8 cm H2O, peripheral oxygen saturation significantly decreased at 3 cm H2O (p=0.021). Heart rate did not change.&lt;/p&gt;&lt;p&gt;&lt;b&gt;CONCLUSIONS: &lt;/b&gt;No differences in CBF and cerebral oxygenation were observed with NCPAP levels in the range 3-8 cm H2O despite a decrease in peripheral oxygenation with 3 cm H2O.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/25336677?dopt=Abstract</style></custom1></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">De Cunto, Angela</style></author><author><style face="normal" font="default" size="100%">Paviotti, Giulia</style></author><author><style face="normal" font="default" size="100%">Ronfani, Luca</style></author><author><style face="normal" font="default" size="100%">Travan, Laura</style></author><author><style face="normal" font="default" size="100%">Bua, Jenny</style></author><author><style face="normal" font="default" size="100%">Cont, Gabriele</style></author><author><style face="normal" font="default" size="100%">Demarini, Sergio</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Can body mass index accurately predict adiposity in newborns?</style></title><secondary-title><style face="normal" font="default" size="100%">Arch Dis Child Fetal Neonatal Ed</style></secondary-title><alt-title><style face="normal" font="default" size="100%">Arch.

Proportionality indexes such as BMI and ponderal index (PI) have been suggested as complementary measures in neonatal growth assessment. Yet, they are still not used in neonates and their correlation with fatness is unknown. The aim of the study was to test the hypothesis that BMI z-score would predict neonatal adiposity. Body composition measurements (ie, fat mass, fat-free mass) by air displacement plethysmography (PEA POD, LMI, Concord-USA), weight and length were obtained in 200 infants ≥36 weeks' gestational age (GA) at birth. Linear regression analysis showed a direct association between BMI z-score and %fat mass (r(2)=0.43, p&lt;0.0001). This association was confirmed independently from sex, GA and maternal prepregnancy BMI. BMI z-score predicted adiposity better than PI. However, both BMI z-score and PI were poor predictors of adiposity at birth.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/24302686?dopt=Abstract</style></custom1></record></records></xml>
