Abstract
Importance Inguinal hernia repair in preterm infants is common and is associated with considerable morbidity. Whether the inguinal hernia should be repaired prior to or after discharge from the neonatal intensive care unit is controversial. Objective To evaluate the safety of early vs late surgical repair for preterm infants with an inguinal hernia. Design, Setting, and Participants A multicenter randomized clinical trial including preterm infants with inguinal hernia diagnosed during initial hospitalization was conducted between September 2013 and April 2021 at 39 US hospitals. Follow-up was completed on January 3, 2023. Interventions In the early repair strategy, infants underwent inguinal hernia repair before neonatal intensive care unit discharge. In the late repair strategy, hernia repair was planned after discharge from the neonatal intensive care unit and when the infants were older than 55 weeks' postmenstrual age. Main Outcomes and Measures The primary outcome was occurrence of any prespecified serious adverse event during the 10-month observation period (determined by a blinded adjudication committee). The secondary outcomes included the total number of days in the hospital during the 10-month observation period. Results Among the 338 randomized infants (172 in the early repair group and 166 in the late repair group), 320 underwent operative repair (86% were male; 2% were Asian, 30% were Black, 16% were Hispanic, 59% were White, and race and ethnicity were unknown in 9% and 4%, respectively; the mean gestational age at birth was 26.6 weeks [SD, 2.8 weeks]; the mean postnatal age at enrollment was 12 weeks [SD, 5 weeks]). Among 308 infants (91%) with complete data (159 in the early repair group and 149 in the late repair group), 44 (28%) in the early repair group vs 27 (18%) in the late repair group had at least 1 serious adverse event (risk difference, -7.9% [95% credible interval, -16.9% to 0%]; 97% bayesian posterior probability of benefit with late repair). The median number of days in the hospital during the 10-month observation period was 19.0 days (IQR, 9.8 to 35.0 days) in the early repair group vs 16.0 days (IQR, 7.0 to 38.0 days) in the late repair group (82% posterior probability of benefit with late repair). In the prespecified subgroup analyses, the probability that late repair reduced the number of infants with at least 1 serious adverse event was higher in infants with a gestational age younger than 28 weeks and in those with bronchopulmonary dysplasia (99% probability of benefit in each subgroup). Conclusions and Relevance Among preterm infants with inguinal hernia, the late repair strategy resulted in fewer infants having at least 1 serious adverse event. These findings support delaying inguinal hernia repair until after initial discharge from the neonatal intensive care unit. Trial Registration ClinicalTrials.gov Identifier: NCT01678638.

Abstract
BACKGROUND Retinopathy of prematurity (ROP) is a developmental retinal vaso-proliferative disease and a leading cause of blindness in children. Early gestational age, low birth weight and unregulated oxygen exposure are the main risk factors for the development of ROP. There are conflicting reports of a possible association between recombinant Erythropoietin (rhEPO) use and an increased risk for the development of ROP. OBJECTIVE To determine whether rhEPO is an independent risk factor for the development of severe ROP among preterm infants with a gestational age of 23 to 32 weeks and a birth weight <1500 g. METHODS We performed a retrospective study of risk factors for ROP on a cohort of 1762 premature infants born between 2009 and 2014, half of whom received rhEPO. To examine the association between treated ROP and rhEPO, a propensity score (PS) analysis was performed using the inverse probability of treatment weighted (IPTW) approach. RESULTS The incidence of treated ROP was 7.3% (129/1762). PS analysis did not show an association between rhEPO and severe ROP needing treatment or ROP stage 2 or higher, in either the whole population or in the subgroup of babies born at 23 to 28 weeks gestation, in whom the incidence of severe ROP was the highest. Of 117 patients treated for Type 1 or worsening stage 3 ROP, 17 were first diagnosed after NICU discharge. CONCLUSION Our study showed no association between Erythropoietin use and severe ROP and highlights the importance of Ophthalmology follow up after hospital discharge.

Abstract
UNLABELLED Erythropoietin treatment is associated with a reduction in moderate to severe bronchopulmonary dysplasia in preterm infants. A regional retrospective study. OBJECTIVE To determine whether premature infants treated with erythropoietin (Epo) in the neonatal period for anemia had a lower incidence of bronchopulmonary dysplasia (BPD), defined as oxygen need at 36 weeks postmenstrual age, and lower rehospitalization rates in the first year of life than infants not exposed. METHODS Retrospective study of a population of infants born at 23 to 32 weeks gestational age, between January 2009 and December 2014, with birthweight ≤1500 g. Patient characteristics, and risk factors for BPD were compared between patients who received erythropoietin, and those not exposed. To examine the association between the outcomes of BPD at 36 weeks PMA, rehospitalization, and erythropoietin treatment, we performed a propensity score (PS) analysis using inverse probability of treatment weighted (IPTW) approach. For comparison, we conducted a logistic regression adjusting for the same covariates used to generate PS using the original population. RESULTS The study population included 1821 preterm infants: 928 received Epo and 893 did not. Epo treatment was associated with a reduction in BPD (18.8% versus 25.9%, p < 0.01) at 36 weeks PMA and reduced median length of stay with lowest BPD rate with Epo initiation before 2 weeks of age. There was no difference in rehospitalization rates in the first year of life. CONCLUSION Erythropoietin treatment was associated with a reduction in BPD but not in rehospitalization rate in the first year of life.

Abstract
RATIONALE Studies have demonstrated that bone marrow-derived cells can be recruited to injured lungs through an unknown mechanism. We hypothesize that marrow progenitors are mobilized into the circulation of patients with cardiac and/or respiratory failure, and may then traffic to and incorporate into the sites of tissue injury. OBJECTIVES To determine whether progenitor populations are increased in the blood of patients with severe acute cardiorespiratory failure placed on extracorporeal membrane oxygenation (ECMO). METHODS Mononuclear cells from ECMO, umbilical cord, and control blood samples were evaluated in colony-forming assays for hematopoietic, mesenchymal, and epithelial cells. Progenitors were identified by proliferative and differentiative capacities, and confirmed by the expression of lineage-specific markers. MEASUREMENTS AND MAIN RESULTS Significantly higher levels of hematopoietic progenitors were observed in ECMO (n = 41) samples than neonatal intensive care unit (n = 16) or pediatric intensive care unit controls (n = 14). Hematopoietic progenitor mobilization increased with time on ECMO support. Mesenchymal progenitors (MSC) were recovered from 18/58 ECMO samples with rapid sample processing (< 4 h) critical to their recovery. MSC were not recovered from normal controls. ECMO-derived MSC had osteogenic, chondrogenic, and adipogenic differentiation potential. The recovery of MSC did not influence survival outcome (61%). Epithelial progenitors were observed in eight ECMO samples but not in control samples. Their presence was associated with a lower survival trend (38%). CONCLUSIONS Hematopoietic, mesenchymal, and epithelial progenitors were mobilized into the circulation of patients on ECMO. This may reflect a response to severe cardiopulmonary injury, blood-foreign surface interactions with the ECMO circuit, and/or hemodilution.
