Objective: To determine the frequency and compare serum calcium levels amongst extremely preterm and very preterm neonates. Study Design: Comparative cross sectional study. Place and Duration of Study: Combined Military Hospital, Multan Pakistan, from May to Oct 2018. Methodology: A total of 217 preterm neonates, born at Combined Military Hospital Multan up to the gestational age of 32 weeks completed from last menstrual period, were included in the study. They were divided in to two group’s i.e. very preterm and extremely preterm neonates. Those born between 28-32 weeks completed of gestation were categorized as severely preterm. Extremely preterm were those born between 24-28 weeks completed of gestation. Venous blood samples were acquired at approximately 36 hours after birth and total serum calcium levels were analyzed. Neonates having total serum calcium levels <7 mg/dL were declared as suffering from hypocalcaemia. Results: Out of 217 neonates, 117 (53.9%) were male while 100 (46.1%) were female. Mean gestational age was 30.98 ± 2.12 weeks while mean parity of the mothers was 2.82 ± 1.08 children. Mean birth weight was 1510.26 ± 142.38 grams. One hundred and seventeen (53.9%) of the preterm neonates suffered from hypocalcaemia with the mean total serum calcium level being 6.58 ± 0.86 mg/dL. Hypocalcaemia was more common in extremely preterm neonates compared to very preterm neonates (p<0.05). Conclusion: Hypocalcaemia is a frequent complication encountered in preterm neonates born between 24-32 weeks gestation. Within these neonates, the frequency of hypocalcaemia is higher in extremely preterm compared to severely preterm babies.

ObjectiveTo test the hypothesis that a strategy of prolonged arterial line (AL) and central venous line (CVL) use is associated with reduced neonatal invasive procedures and improved growth of the thalamus in extremely preterm neonates (<28 weeks' gestation).MethodsTwo international cohorts of very preterm neonates (n = 143) with prolonged (≥14 days) or restricted (<14 days) use of AL/CVL were scanned serially with MRI. General linear models were used to determine the association between skin breaks and thalamic volumes, accounting for clinical confounders and site differences. Children were assessed at preschool age on standardized tests of motor and cognitive function. Outcome scores were assessed in relation to neonatal thalamic growth.ResultsProlonged AL/CVL use in neonates (n = 86) was associated with fewer skin breaks (median 34) during the hospital stay compared to restricted AL/CVL use (n = 57, median 91, 95% confidence interval [CI] 60.35–84.89). Neonates with prolonged AL/CVL use with fewer skin breaks had significantly larger thalamic volumes early in life compared to neonates with restricted line use (B = 121.8, p = 0.001, 95% CI 48.48–195.11). Neonatal thalamic growth predicted preschool-age cognitive (B = 0.001, 95% CI 0.0003–0.001, p = 0.002) and motor scores (B = 0.01, 95% CI 0.001–0.10, p = 0.02). Prolonged AL/CVL use was not associated with greater incidence of sepsis or multiple infections.ConclusionsProlonged AL/CVL use in preterm neonates may provide an unprecedented opportunity to reduce invasive procedures in preterm neonates. Pain reduction in very preterm neonates is associated with optimal thalamic growth and neurodevelopment.

Objective The fetal inflammatory response syndrome (FIRS) is characterized by elevated concentrations of inflammatory cytokines in fetal blood, with preterm delivery and morbidity. Umbilical cord serum interleukin-6 (UC-s-IL-6) is an ideal marker for detecting FIRS. However, the effect of gestational age (GA) on UC-s-IL-6 levels has not been reported. This study aimed to determine the relationship between GA and UC-s-IL-6 levels, and GA-dependent cutoff values of UC-s-IL-6 levels for detecting fetal inflammation. Study Design UC-s-IL-6 concentrations were measured in 194 newborns (44 extremely preterm newborns (EPNs) at 22–27 weeks' GA, 68 very preterm newborns (VPNs) at 28–31 weeks' GA, and 82 preterm newborns (PNs) at 32–34 weeks' GA). Linear regression analyses were used to correlate GA and UC-s-IL-6 levels. Receiver operating characteristic (ROC) curves analyses were performed for detecting the presence of funisitis, as the histopathological counterpart of FIRS. Results A significant negative correlation between GA and UC-s-IL-6 levels was found in newborns with severe funisitis (r s =  − 0.427, p = 0.004) and those with mild funisitis (r s =  − 0.396, p = 0.025). ROC curve analyses revealed the area under the curve for detecting funisitis were 0.856, 0.837, and 0.622 in EPNs, VPNs, and PNs, respectively. The UC-s-IL-6 cutoff value in EPNs (28.1 pg/mL) exceeded those in VPNs and PNs (3.7 and 3.0 pg/mL, respectively). Conclusion UC-s-IL-6 levels were inversely correlated with GA especially in newborns with funisitis. Such GA dependency of UC-s-IL-6 should be considered for detecting fetal inflammation. Key Points
