Purpose: Necrotizing enterocolitis (NEC) and spontaneous intestinal perforation (SIP) are severe gastrointestinal complications of prematurity. The clinical presentation and treatment of NEC and SIP (peritoneal drain vs laparotomy) can overlap; however, the pathogenesis is distinct. Therefore, a patient initially treated for SIP can subsequently develop NEC. This phenomenon has only been described in case reports, and no risk factor evaluation exists. We evaluate clinical characteristics, risk factors, and outcomes of patients treated for a distinct episode of NEC after SIP.

Methods: We performed a retrospective review of very low birth weight (<1500 g) neonates who presented with pneumoperitoneum between 07/2004 and 09/2022. Data was obtained from two separate neonatal intensive care units that were part of the same institution. Patients with an initial preoperative, intraoperative, or pathological diagnosis of NEC were excluded. Patients with an intraoperative diagnosis of SIP or preoperative diagnosis of SIP successfully treated with a peritoneal drain (PD) were evaluated. Patients subsequently treated (medically or surgically) for NEC after SIP were then compared to SIP-alone patients. Clinical characteristics included demographics, gestational age (GA), birth weight (BW), perinatal risk factors (chorioamnionitis, steroids, indomethacin), postoperative feeding regimen, and length of stay (LOS) were compared.

Results: Of the 278 patients included, 31 (11.2%) patients had NEC after SIP. There was no difference in GA (25 weeks vs 25 weeks, p = 0.933) or BW (760 g vs 735 g, p = 0.370) between NEC after SIP vs SIP alone cohorts, respectively. Twenty (64%) of NEC after-SIP patients were previously treated with LP. NEC after SIP occurred with a median onset of 56 days. Pneumatosis was the most frequent (81%) presenting symptom and 12 (39%) patients had hematochezia. Four (12.9%) patients required LP for NEC and all had NEC intraoperatively and on pathology. A majority (77.4%) of patients were on breast milk (BM) at time of NEC diagnosis. NEC after SIP patients had lower maternal age at delivery (29.0 vs 25.0, p = 0.055) and the incidence of NEC after LP (primary or failed drain) was higher than PD alone (16.7% vs 6.2%, p = 0.007). NEC after SIP patients had longer LOS (135 vs 81, p < 0.001).

Conclusion: We report an 11.2% incidence of NEC at a median of 56 days following successful treatment of SIP, resulting in increased LOS. SIP patients are a high-risk cohort and protocols to prevent this phenomenon should be investigated.

Objective: Shared decision-making (SDM) between parents facing extremely preterm delivery and the medical team is recommended to develop the best course of action for neonatal care. We aimed to describe the creation and testing of a literature-based checklist to assess SDM practices for consultation with parents facing extremely preterm delivery.

Study design: The checklist of SDM counseling behaviors was created after literature review and with expert consensus. Mock consultations with a standardized patient facing extremely preterm delivery were performed, video-recorded, and scored using the checklist. Intraclass correlation coefficients and Cronbach's alpha were calculated.

Result: The checklist was moderately reliable for all scorers in aggregate. Differences existed between subcategories within classes of scorer, and between scorer classes. Agreement was moderate between expert scorers, but poor between novice scorers. Internal consistency of the checklist was excellent (Cronbach's alpha = 0.93).

Conclusion: This novel checklist for evaluating SDM shows promise for use in future research, training, and clinical settings.

Objective: Evaluate the impact of a sodium (Na) supplementation protocol based upon urine Na concentration on growth parameters and morbidities.

Study design: Retrospective cohort study of infants 26^0/7-33^6/7 weeks gestational age (GA) cared for before (2012-15, n = 310) and after (2016-20, n = 382) implementation of the protocol. Within- and between-group changes over time were assessed using repeated measures generalized linear models.

Results: For infants 26^0/7-29^6/7 weeks GA, utilization of the protocol was associated with increased mean body weight z-score at 8-weeks postnatal age, increased mean head circumference z-score at 16-weeks postnatal age, and decreased time on mechanical ventilation (all p < 0.02). No impact on growth was identified for infants 30-33^6/7 weeks GA. Incidences of hypertension, hypernatremia, bronchopulmonary dysplasia, necrotizing enterocolitis, and culture positive sepsis were unaffected by the protocol.

Conclusion: Protocolized Na supplementation is associated with improved growth and reduced time on invasive mechanical ventilation in extremely preterm infants without increasing incidence of morbidities.

Objective: Compare the use of nonsteroidal anti-inflammatory drugs (NSAIDs) with placebo/expectant management in preterm infants at 28 weeks or less gestational age with a large Patent Ductus (PDA).

Study design: A meta-analysis of RCTs following PRISMA guidelines comparing the use of NSAIDs with placebo/expectant management in extremely preterm infants with a large PDA.

Results: There were no significant differences between the NSAIDs and placebo/expectant groups for all-cause mortality (RR 1.27; 95% CI 0.97-1.65; p = 0.081). However, the ibuprofen subgroup showed a significant difference in all-cause mortality (RR 1.36; 95% CI 1.03-1.80; p = 0.03) favoring the placebo/expectant group.

Conclusion: In extremely preterm infants with a large PDA on ultrasound, early treatment with NSAIDs provides no additional clinical benefit compared to placebo/expectant treatment. Ibuprofen was associated with an increased risk ratio for all-cause mortality in the subgroup analysis.

Shared decision-making in pediatrics can be problematic when disagreements arise. The impermissible-permissible-obligatory (I-P-O) framework helps define the limits of parental authority when clinicians disagree with parents. There is little guidance in the literature, however, on making critical clinical decisions when parents disagree with each other. We use a clinical case involving parental disagreement over resuscitation at borderline gestational age to provide context for an analysis of several potential approaches based on established ethical principles of pediatric decision-making. We identify four potential options for delivery room care: (1) Defer to the pregnant parent; (2) withhold resuscitation unless both parents agree to it; (3) attempt resuscitation if either parent requests it; (4) decide about resuscitation using a framework of advisability. The merits and flaws of each approach are discussed. We propose an expansion of the I-P-O framework that uses consideration of clinical details, an assessment of the patient's best interest, and parental values to determine clinical advisability to guide decision-making in the setting of parental discordance.

Objective: To predict pharmacotherapy for NOWS based on factors available shortly after birth.

Study design: A multi-center, retrospective study of 1377 opioid exposed newborns between 2016 and 2017 dichotomized based on pharmacologic treatment (N = 665 treated, N = 712 not treated) was conducted. A multilevel mixed-effect logistic regression model that considered cluster effect from sites determined significant maternal and newborn factors associated with pharmacotherapy, which were combined in a nomogram to predict probability of treatment for infants at each participating site.

Results: Factors predictive of treatment were: no breastmilk (1.76, 1.30-2.39; p < 0.001), male sex (1.39, 1.05-1.83; p = 0.021), polysubstance exposure (1.53, 1.15-2.06; p = 0.004), inadequate prenatal care (1.51, 1.07-2.13; p < 0.018) and Methadone (6.08, 4.03-9.27; p < 0.001) or Buprenorphine (1.86, 1.29-2.69; p < 0.001). A site-specific nomogram provided the probability of treatment for individual newborns.

Conclusion: Six factors available shortly after birth can be combined to predict site-specific use of medication for NOWS. If confirmed, the nomogram may identify at-risk newborns.

Objective: We previously reported the possible pathogenic role, among infants born ≤29 weeks, of transfusions in bronchopulmonary dysplasia. The present study examined this association in infants born >31 weeks.

Study design: Analysis of red blood cell (RBC) and platelet transfusions in five NICUs to infants born >31 weeks, and chronic neonatal lung disease (CNLD) at six-weeks of age.

Results: Seven-hundred-fifty-one infants born >31 weeks were still in the NICU when six-weeks of age. CNLD was identified in 397 (53%). RBC and platelet transfusions were independently associated with CNLD after controlling for potential confounders. For every transfusion, the adjusted odds of developing CNLD increased by a factor of 1.64 (95% CI, 1.38-2.02; p < 0.001).

Conclusions: Among NICU patients born >31 weeks, transfusions received by six weeks are associated with CNLD incidence and severity. Though we controlled for known confounding variables in our regression models, severity of illness is an important confounder that limits our conclusions.
