Fatty Acid Deficiency

OBJECTIVE A mixture of soybean, medium-chain triglycerides, olive, and fish oils (SMOF) contains higher α-tocopherol and n-3 polyunsaturated fatty acids and lower phytosterol content compared with conventional soybean oil lipid emulsions (SOLE). We sought to characterize plasma total fatty acid profiles (FAPs) and assess the tolerability of long-term SMOF therapy in extremely preterm infants. METHODS We retrospectively evaluated infants born <28 weeks gestational age who received at least 30 consecutive days of SMOF between July 2016 and June 2019. We evaluated monthly FAPs and biochemical tolerance to SMOF using direct bilirubin (DB) and triglyceride (TG) levels. Growth parameters were evaluated longitudinally until discharge. RESULTS Sixteen patients with median gestational age 24 weeks (IQR, 23–25 weeks) received SMOF for median 76 days (IQR, 52–130 days). Fourteen patients had necrotizing enterocolitis (NEC) requiring surgical intervention and 15 patients received SOLE for median 19 days (IQR, 14–26 days) prior to switching to SMOF. Median docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) levels were elevated, whereas the remaining fatty acid levels fell within reported reference ranges. There were no incidents of essential fatty acid deficiency (triene to tetraene ratio >0.2) or hypertriglyceridemia (TG >200 mg/dL) with a general downtrend in DB after the first month on SMOF. All growth Z-scores declined throughout hospital stay. CONCLUSIONS Infants who received SMOF had a more pronounced elevation in DHA than EPA, of which the clinical significance remains unknown. Growth Z-scores declined with SMOF but were confounded by a high prevalence of surgically treated NEC.

Background and Objectives: Retinopathy of prematurity (ROP) is the leading cause of blindness in preterm infants. We studied the relationship between different perinatal characteristics, i.e., sex; gestational age (GA); birth weight (BW); C-reactive protein (CRP) and lactate dehydrogenase (LDH) concentrations; ventilation, continuous positive airway pressure (CPAP), and surfactant administration; and the incidence of Stage 1–3 ROP. Materials and Methods: This study included 247 preterm infants with gestational age (GA) < 32 weeks that were successfully screened for ROP. Univariate and multivariate binary analyses were performed to find the most significant risk factors for ROP (Stage 1–3), while multivariate multinomial analysis was used to find the most significant risk factors for specific ROP stages, i.e., Stage 1, 2, and 3. Results: The incidence of ROP (Stage 1–3) was 66.40% (164 infants), while that of Stage 1, 2, and 3 ROP was 15.38% (38 infants), 27.53% (68 infants), and 23.48% (58 infants), respectively. Following univariate analysis, multiple perinatal characteristics, i.e., GA; BW; and ventilation, CPAP, and surfactant administration, were found to be statistically significant risk factors for ROP (p < 0.001). However, in a multivariate model using the same characteristics, only BW and ventilation were significant ROP predictors (p < 0.001 and p < 0.05, respectively). Multivariate multinomial analysis revealed that BW was only significantly correlated with Stage 2 and 3 ROP (p < 0.05 and p < 0.001, respectively), while ventilation was only significantly correlated with Stage 2 ROP (p < 0.05). Conclusions: The results indicate that GA; BW; and the use of ventilation, CPAP, and surfactant were all significant risk factors for ROP (Stage 1–3), but only BW and ventilation were significantly correlated with ROP and specific stages of the disease, namely Stage 2 and 3 ROP and Stage 2 ROP, respectively, in multivariate models.

Abstract Background Regional variation in cost of neonatal intensive care for extremely preterm infant is not documented. We sought to evaluate regional variation that may lead to benchmarking and cost saving. Methods An analysis of a Canadian national costing data from the payor perspective. We included all liveborn 23–28-week preterm infants in 2011–2015. We calculated variation in costs between provinces using non-parametric tests and a generalized linear model to evaluate cost variation after adjustment for gestational age, survival, and length of stay. Results We analysed 6932 infant records. The median total cost for all infants was $66,668 (Inter-Quartile Range (IQR): $4920–$125,551). Medians for the regions varied more than two-fold and ranged from $48,144 in Ontario to $122,526 in Saskatchewan. Median cost for infants who survived the first 3 days of life was $91,000 (IQR: $56,500–$188,757). Median daily cost for all infants was $1940 (IQR: $1518–$2619). Regional variation was significant after adjusting for survival more than 3 days, length of stay, gestational age, and year (pseudo-R2 = 0.9, p < 0.01). Applying the model on the second lowest-cost region to the rest of the regions resulted in a total savings of $71,768,361(95%CI: $65,527,634–$81,129,451) over the 5-year period ($14,353,672 annually), or over 11% savings for the total program cost of $643,837,303 over the study period. Conclusion Costs of neonatal intensive care are high. There is large regional variation that persists after adjustment for length of stay and survival. Our results can be used for benchmarking and as a target for focused cost optimization, savings, and investment in healthcare.

This paper proposes and employs a framework for determining whether life-saving treatment at birth is in the best interests of extremely preterm infants, given uncertainty about the outcome of such a choice. It argues that given relevant data and plausible assumptions about the well-being of babies with various outcomes, it is typically in the best interests of even the youngest preterm infants—those born at 22 weeks gestational age—to receive life-saving treatment at birth.

Abstract The aim of our study was to observe the temporal distribution of serum N-terminal pro-brain natriuretic peptide (NT-proBNP) in premature infants of ≤ 31 weeks of gestational age (GA) during the first weeks of life. NT-proBNP values of 118 preterm infants born ≤ 31 weeks GA were determined during the first week of life, after 4 ± 1 weeks of life, and at a corrected GA of 36 ± 2 weeks. Infants were divided into two groups: those without relevant complications and those with complications related to prematurity. NT-proBNP values of infants without complications define our exploratory reference values. The Median NT-proBNP level of these infants was 1896 ng/l (n = 27, interquartile range (IQR): 1277–5200) during the first week of life, 463 ng/l (n = 26, IQR: 364–704) at 4 ± 1 weeks of life, and 824 ng/l (n = 33, IQR: 714–1233) at a corrected GA of 36 ± 2 weeks. Infants born < 28 + 0 weeks GA had significantly higher NT-proBNP values (n = 9, median: 5200, IQR: 1750–8972) than infants born ≥ 28 + 0–31 weeks GA (n = 18, median: 1528, IQR: 838–3052; p = 0.017). Growth restriction or PDA status could not account for the difference in NT-proBNP values between GA groups. Conclusions: The results of our observational and cross-sectional study describe exploratory reference values for NT-proBNP levels in preterm infants of ≤ 31 weeks GA according to postnatal age. NT-proBNP levels during the first week of life are high and widely distributed in preterm infants and decrease subsequently to reach a distinctly lower and stable plateau at around 1 month of life. Our results suggest an influence of GA on NT-proBNP values in the first week of life. What is Known:• Several complications related to prematurity, e.g., hemodynamically significant PDA, pulmonary hypertension, bronchopulmonary dysplasia, and retinopathy of prematurity, have been associated with a temporary rise in NT-proBNP values in preterm infants during their first weeks of life.What is New:• This observational study provides reference values for NT-proBNP levels of very and extremely preterm infants during their first weeks of life.• In premature infants without complications, NT-proBNP values during their first week of life depend on gestational age at birth.

Intermittent hypoxaemia (IH) events are well described in extremely preterm infants, but the occurrence of IH patterns in more mature preterm infants remains unclear. The objective of this study was to characterise the effect of gestational age on early postnatal patterns of IH in extremely (<28 weeks), very (28–<32 weeks) and moderately (32–<34 weeks) preterm infants. As expected, extremely preterm infants had a significantly higher frequency of IH events of longer durations and greater time with hypoxaemia versus very and moderately preterm infants. In addition, the postnatal decrease in IH duration was comparable in the very and moderately preterm infants. This progression of IH events should assist clinicians and families in managing expectations for resolution of IH events during early postnatal life.

The Relationship

Objective To examine the relationship between admission systolic blood pressure (SBP) and adverse neonatal outcomes. Specifically, we aimed to identify the optimal SBP that is associated with the lowest rates of adverse outcomes in extremely preterm infants of ≤ 26 weeks' gestation. Methods In this retrospective study, inborn neonates born at ≤ 26 weeks' gestational age and admitted to tertiary neonatal units participating in the Canadian Neonatal Network between 2003 and 2009 were included. The primary outcome was early mortality (≤ 7 days). Secondary outcomes included severe brain injury, late mortality, and a composite outcome defined as early mortality or severe brain injury. Nonlinear multivariable logistic regression models examined the relationship between admission SBP and outcomes. Results Admission SBP demonstrated a U-shaped relationship with early mortality, severe brain injury, and composite outcome after adjustment for confounders (p < 0.01). The lowest risks of early mortality, severe brain injury, and composite outcome occurred at admission SBPs of 51, 55, and 54 mm Hg, respectively. Conclusion In extremely preterm infants of ≤ 26 weeks' gestational age, the relationship between admission SBP, and early mortality and severe brain injury was “U-shaped.” The optimal admission SBP associated with lowest rates of adverse outcome was between 51 and 55 mm Hg.
