51 THE PREDICTIVE VALUE OF ABNORMAL NEUROLOGICAL DEVELOP MENT AT 6 WEEKS OF CORRECTED AGE (CA) FOR ABNORMAL VISUAL FUNCTIONS AT 1 YEAR IN VERY LOW BIRTH WEIGHT (VLBW) INFANTS

AbstractTo assess the accuracy of lipopolysaccharide binding protein (LBP) for diagnosing late-onset neonatal sepsis (LONS) in very low birth weight (VLBW) infants.Observational, prospective study. We assessed the diagnostic performance of LBP in 26 suspected LONS episodes among 54 patients. Proven and probable LONS episodes were recorded according to established criteria. Receiver operating characteristic curve analysis was performed to evaluate LBP’s ability to predict LONS.LONS was diagnosed in 17 of 26 episodes. LBP levels were significantly higher in confirmed LONS episodes (P<0.001). The area under the curve of LBP was 0.89. A cut-off of 17.5 μg/mL had a sensitivity of 94.1%, a specificity of 77.8%, a positive predictive value of 88.9% and a negative predictive value of 87.5%.Serum LBP measurement may be useful as an additional tool in the evaluation of suspected LONS in VLBW infants.

Over Time

Introduction: In very low birth weight (<1,500 g, VLBW) infants, morbidity and mortality have decreased substantially during the past decades, and both are known to be lower in girls than in boys. In this study, we assessed sex-specific changes over time in length of hospital stay (LOHS) and postmenstrual age at discharge (PAD), in addition to survival in VLBW infants. Methods: This is a single-center retrospective cohort analysis based on quality assurance data of VLBW infants born from 1978 to 2018. Estimation of sex-specific LOHS over time was based on infants discharged home from neonatal care or deceased. Estimation of sex-specific PAD over time was based on infants discharged home exclusively. Analysis of in-hospital survival was performed for all VLBW infants. Results: In 4,336 of 4,499 VLBW infants admitted from 1978 to 2018 with complete data (96.4%), survival rates improved between 1978–1982 and 1993–1997 (70.8 vs. 88.3%; hazard ratio (HR) 0.20, 95% confidence interval 0.14, 0.30) and remained stable thereafter. Boys had consistently higher mortality rates than girls (15 vs. 12%, HR 1.23 [1.05, 1.45]). Nonsurviving boys died later compared to nonsurviving girls (adjusted mean survival time 23.0 [18.0, 27.9] vs. 20.7 [15.0, 26.3] days). LOHS and PAD assessed in 3,166 survivors displayed a continuous decrease over time (1978–1982 vs. 2013–2018: LOHS days 82.9 [79.3, 86.5] vs. 60.3 [58.4, 62.1] days); PAD 40.4 (39.9, 40.9) vs. 37.4 [37.1, 37.6] weeks). Girls had shorter LOHS than boys (69.4 [68.0, 70.8] vs. 73.0 [71.6, 74.4] days) and were discharged with lower PAD (38.6 [38.4, 38.8] vs. 39.2 [39.0, 39.4] weeks). Discussion/Conclusions: LOHS and PAD decreased over the last 40 years, while survival rates improved. Male sex was associated with longer LOHS, higher PAD, and higher mortality rates.

Background Gastrointestinal (GI) perforation is a risk factor for mortality in very low birth weight (VLBW) infants. Little data exist regarding pretreatment factors and patient characteristics known to independently correlate with risk of death. Materials and Methods A retrospective review of all VLBW infants who sustained GI perforation between 2011 and 2018 was conducted. Birth, laboratory, and disease-related factors of infants who died were compared to those who survived. Results 42 VLBW infants who sustained GI perforations were identified. Eleven (26.19%) died. There were no significant differences in birth-related factors, hematological lab levels at diagnosis, presence of pneumatosis, or bacteremia. Portal venous gas ( P = .03), severe metabolic acidosis ( P < .01), and elevated lactate at diagnosis ( P < .01) were statistically more likely to occur among infants who died. Discussion Portal venous gas, severe metabolic acidosis, and elevated lactate were associated with an increased risk of mortality among VLBW infants who develop a GI perforation. Further research is required to better identify risk factors.

Focal Intestinal Perforation

Introduction We present a single-center experience with very low birth weight (VLBW) infants with focal intestinal perforation (FIP), comparing the results of primary anastomosis (PA) and stoma opening (SO). Materials and Methods Clinical records of VLBW infants with FIP who underwent surgery between 2006 and 2015 were reviewed. Patients were divided into two groups according to the procedure performed: limited bowel resection and PA or SO. Patients with gastric perforation or patients who underwent clip and drop were excluded. Information regarding birth weight (BW), gestational age (GA), weight at surgery (WS), number of abdominal reoperations, duration of parenteral nutrition (PN), and demise was recorded. Results In this study, 40 patients were included: 22 in PA group and 18 in SO group. BW was 865 g in PA and 778 in SO (p-value: 0.2). GA was 26.1 weeks in PA and 25.6 in SO (p-value: 0.3). WS was 1,014 g in PA and 842 in SO (p-value: 0.09). Duration of surgery was 115 minutes in PA and 122 in SO (p-value: 0.67). Five patients (23%) belonging to PA group developed complications and required SO. Five patients (23%) demised in PA group and six (33%) in SO (p-value: 0.2). Seventeen abdominal reoperations were performed in PA group and 22 in SO group (p-value: 0.08). Conclusion Both procedures appear to be safe. When possible, PA should be performed as it reduces the number of abdominal reinterventions.

Rbc Transfusion

Background: Red blood cell (RBC) transfusion improves cardiorespiratory status of preterm infants by increasing circulating hemoglobin, improving tissue oxygenation, and reducing cardiac output. However, RBC transfusion itself has also been suggested to negatively affect short-term outcomes such as intraventricular hemorrhage (IVH), bronchopulmonary dysplasia (BPD), retinopathy of prematurity (ROP), and necrotizing enterocolitis (NEC) in premature infants.Purpose: This study aimed to analyze the relationship between RBC transfusion and short-term outcomes in very low birth weight (VLBW) infants (birth weight, <1,500 g).Methods: We retrospectively reviewed the medical records of VLBW infants admitted to the Soonchunhyang University Bucheon Hospital between October 2010 and December 2017. Infants who died during hospitalization were excluded. The infants were divided into 2 groups according to RBC transfusion status. We investigated the relationship between RBC transfusion and short-term outcomes including BPD, ROP, NEC, and IVH.Results: Of the 250 enrolled VLBW infants, 109 (43.6%) underwent transfusion. Univariate analysis revealed that all shortterm outcomes except early-onset sepsis and patent ductus arteriosus were associated with RBC transfusion. In multivariate analysis adjusted for gestational age, birth weight and Apgar score at 1 minute, RBC transfusion was significantly correlated with BPD (odds ratio [OR], 5.42; P<0.001) and NEC (OR, 3.40; P= 0.009).Conclusion: RBC transfusion is significantly associated with adverse clinical outcomes such as NEC and BPD in VLBW infants. Careful consideration of the patient’s clinical condition and appropriate guidelines is required before administration of RBC transfusions.

Cognitive Score

Purpose: To assess the predictive validity of the Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III) cognitive scores at 6 months of corrected age (CA) for cognitive outcomes at 24 months of CA in very-low-birth-weight (VLBW) infants and investigate the predictors of change in cognitive outcomes.Methods: We retrospectively evaluated VLBW children enrolled in the Taiwan Premature Infant Follow-up Network between 2010 and 2015 and completed the Bayley-III at CA of 6 and 24 months. The predictive validity of the cognitive performance at 6-month CA for the cognitive outcomes at 24-month CA was analyzed. The positive and negative predictive factors were also evaluated using logistic regression. Cut-off scores of <70 and <85 were used to identify lower functioning groups based on the Bayley-III definition.Results: A total of 2,972 VLBW children, born with a mean weight of 1116.4 ± 257.5 g and mean gestational age of 29.0 ± 2.8 weeks, were evaluated. A cognitive score of <70 at 6-month CA had a positive predictive value (PPV) of 27.4% (95% confidence interval [CI]: 19.2–35.7%) for a cognitive score of <70 at 24-month CA, while the negative predictive value (NPV) was 97.3% (95% CI: 96.7–97.9%). A cut-off score of 85 had a PPV of 33.6% (95% CI: 28.1–39.0%) and an NPV of 87.7% (95% CI: 86.4–88.9%). Abnormal muscle tone at 6 months was a risk factor for cognitive function decline at 24 months for both Bayley-III cognitive cut-off scores: scores of 70 (adjusted odds ratio [AOR]: 2.8; 95% CI: 1.5–5.5) and 85 (AOR: 2.6; 95% CI: 1.6–4.1). Lower maternal socioeconomic status was associated with a worsening of the cognitive function in infants at 24 months who scored ≥85 at 6 months (AOR: 1.6; 95% CI: 1.2–2.0).Conclusion: Subnormal Bayley-III cognitive scores at 6-month CA were not predictive of subnormal cognitive function at 24-month CA. In children with normal cognition during early infancy, abnormal muscle tone and lower maternal socioeconomic status may influence the cognitive developing process; this highlighted the importance of early identification of high risk infants and complete preterm infant-associated public health policies to promote an improved neurodevelopmental outcome.
