Difference in levels of SARS-CoV-2 S1 and S2 subunits- and nucleocapsid protein-reactive SIgM/IgM, IgG and SIgA/IgA antibodies in human milk.

Abstract: This study evaluated the presence and the levels of antibodies reactive to SARS-CoV-2 S1 and S2 subunits (S1 + S2), and nucleocapsid protein. The levels of SARS-CoV-2 S1 + S2- and nucleocapsid-reactive SIgM/IgM, IgG and SIgA/IgA were measured in human milk samples from 41 women during the COVID-19 pandemic (2020-HM) and from 16 women 2 years prior to the outbreak (2018-HM). SARS-CoV-2 S1 + S2-reactive SIgA/IgA, SIgM/IgM and IgG were detected in 97.6%, 68.3% and 58.5% in human milk whereas nucleocapsid-reactive antibodies were detected in 56.4%, 87.2% and 46.2%, respectively. S1 + S2-reactive IgG was higher in milk from women that had symptoms of viral respiratory infection(s) during the last year than in milk from women without symptom. S1 + S2- and nucleocapsid-reactive IgG were higher in the 2020-HM group compared to the 2018-HM group. The presence of SARS-CoV-2-reactive antibodies in human milk could provide passive immunity to breastfed infants and protect them against COVID-19 diseases.

COVID-19: neonatal-perinatal perspectives.

Abstract: The coronavirus disease 2019 (COVID-19) pandemic, resulting from infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has caused severe and widespread illness in adults, including pregnant women, while rarely infecting neonates. An incomplete understanding of disease pathogenesis and viral spread has resulted in evolving guidelines to reduce transmission from infected mothers to neonates. Fortunately, the risk of neonatal infection via perinatal/postnatal transmission is low when recommended precautions are followed. However, the psychosocial implications of these practices and racial/ethnic disparities highlighted by this pandemic must also be addressed when caring for mothers and their newborns. This review provides a comprehensive overview of neonatal-perinatal perspectives of COVID-19, ranging from the basic science of infection and recommendations for care of pregnant women and neonates to important psychosocial, ethical, and racial/ethnic topics emerging as a result of both the pandemic and the response of the healthcare community to the care of infected individuals.

Early assessment of lung aeration using an ultrasound score as a biomarker of developing bronchopulmonary dysplasia: a prospective observational study.

Abstract: The objective of this study was to assess the predictive value of a lung ultrasound (LUS) score in the development of moderate–severe bronchopulmonary dysplasia (sBPD). This was a prospective observational diagnostic accuracy study in a third-level neonatal intensive care unit. Preterm infants with a gestational age below 32 weeks were included. A LUS score (range 0–24 points) was calculated by assessing aeration semiquantitatively (0–3 points) in eight lung zones on the 7th day of life (DOL) and repeated on the 28th DOL. ROC curves and logistic regression were used for analysis. Forty-two preterm infants were included. The LUS on the 7th DOL had an area under the receiver operating characteristic curve (AUROC) of 0.94 (95% CI: 0.87–1) for the prediction of sBPD (optimal cutoff of ≥8 points: sensitivity 93%, specificity 91%). The LUS score was independently associated with sBPD [OR 2.1 (95% CI: 1.1–3.9), p = 0.022, for each additional point in the score]. Conclusions: Lung aeration as assessed by LUS on the 7th DOL may predict the development of sBPD.

Hospital variation in admissions to neonatal intensive care units by diagnosis severity and category.

Abstract: To examine interhospital variation in admissions to neonatal intensive care units (NICU) and reasons for the variation. 2010–2012 linked birth certificate and hospital discharge data from 35 hospitals in California on live births at 35–42 weeks gestation and ≥1500 g birth weight were used. Hospital variation in NICU admission rates was assessed by coefficient of variation. Patient/hospital characteristics associated with NICU admissions were identified by multivariable regression. Among 276,489 newborns, 6.3% were admitted to NICU with 34.5% of them having mild diagnoses. There was high interhospital variation in overall risk-adjusted rate of NICU admission (coefficient of variation = 26.2) and NICU admission rates for mild diagnoses (coefficient of variation: 46.4–74.0), but lower variation for moderate/severe diagnoses (coefficient of variation: 8.8–14.1). Births at hospitals with more NICU beds had a higher likelihood of NICU admission. Interhospital variation in NICU admissions is mostly driven by admissions for mild diagnoses, suggesting potential overuse.

Recent Advances in Pathophysiology and Management of Transient Tachypnea of Newborn

Abstract: Transient tachypnea of newborn (TTN) results from failure of the newborn to effectively clear the fetal lung fluid soon after birth. TTN represents the most common etiology of respiratory distress in term gestation newborns and sometimes requires admission to the neonatal intensive care unit. TTN can lead to maternal-infant separation, the need for respiratory support, extended unnecessary exposure to antibiotics and prolonged hospital stays. Recent evidence also suggests that TTN may be associated with wheezing syndromes later in childhood. New imaging modalities such as lung ultrasound can help in the diagnosis of TTN and early management with distending pressure using continuous positive airway pressure may prevent exacerbation of respiratory distress.

Racial discrepancy in pulse oximeter accuracy in preterm infants

Abstract: Objective Pulse oximetry is commonly used in Neonatology, however recent adult data suggest racial disparity in accuracy, with overestimation of oxygen saturation for Black patients. Study design Black and White infants Results A total of 294 infants (124 Black, 170 White) were identified with mean GA of 25.8 ± 2.1 weeks and mean BW of 845 ± 265 grams, yielding 4387 SaO2-SpO2 datapoints. SpO2 overestimation, measured by mean bias, was 2.4-fold greater for Black infants and resulted in greater occult hypoxemia (SpO2 > 90% when SaO2 Conclusion There is a modest but consistent difference in SpO2 error between Black and White infants, with increased incidence of occult hypoxemia in Black infants.

Neonatal NIRS monitoring: recommendations for data capture and review of analytics

Abstract: Brain injury is one of the most consequential problems facing neonates, with many preterm and term infants at risk for cerebral hypoxia and ischemia. To develop effective neuroprotective strategies, the mechanistic basis for brain injury must be understood. The fragile state of neonates presents unique research challenges; invasive measures of cerebral blood flow and oxygenation assessment exceed tolerable risk profiles. Near-infrared spectroscopy (NIRS) can safely and non-invasively estimate cerebral oxygenation, a correlate of cerebral perfusion, offering insight into brain injury-related mechanisms. Unfortunately, lack of standardization in device application, recording methods, and error/artifact correction have left the field fractured. In this article, we provide a framework for neonatal NIRS research. Our goal is to provide a rational basis for NIRS data capture and processing that may result in better comparability between studies. It is also intended to serve as a primer for new NIRS researchers and assist with investigation initiation.

Neurodevelopmental outcomes following bevacizumab treatment for retinopathy of prematurity: a systematic review and meta-analysis.

Abstract: Objective To systematically review the studies exploring the association between bevacizumab and neurodevelopmental outcomes. Methods Embase, Medline, CINAHL, and Cochrane Library databases were searched for studies examining neurodevelopmental outcomes of preterm infants treated with bevacizumab compared to laser ablation or cryotherapy for severe retinopathy of prematurity (ROP). Results Thirteen studies (clinical trial = 1; cohort studies = 12) were included. Random-effects model meta-analysis showed significant increased odds of cognitive impairment associated with bevacizumab treatment on both unadjusted (unadjusted odds ratio (OR) 1.61; 95% confidence interval (CI) 1.12, 2.30) and adjusted analyses (adjusted OR 1.90; 95% CI 1.22, 2.97). Infants treated with bevacizumab for severe ROP had significantly lower Bayley-III cognitive (mean difference (MD) -1.66; 95% CI -3.21, -0.12), and language composite scores (MD -5.50; 95% CI -8.24, -2.76) compared to infants treated with laser ablation or cryotherapy. Conclusion Bevacizumab treatment for severe ROP is associated with increased risk of cognitive impairment and lower cognitive and language scores in preterm infants.

Practical approaches to sedation and analgesia in the newborn

Abstract: The prevention, assessment, and treatment of neonatal pain and agitation continues to challenge clinicians and researchers. Substantial progress has been made in the past three decades, but numerous outstanding questions remain. In this setting, clinicians must establish safe and compassionate standardized practices that consider available efficacy data, long-term outcomes, and research gaps. Novel approaches with limited data must be carefully considered against historic standards of care with robust data suggesting limited benefit and clear adverse effects. This review summarizes available evidence while suggesting practical clinical approaches to pain assessment and avoidance, procedural analgesia, postoperative analgesia, sedation during mechanical ventilation and therapeutic hypothermia, and the issues of tolerance and withdrawal. Further research in all areas represents an urgent priority for optimal neonatal care. In the meantime, synthesis of available data offers clinicians challenging choices as they balance benefit and risk in vulnerable critically ill neonates.

Perinatal care experiences among racially and ethnically diverse mothers whose infants required a NICU stay.

Abstract: To learn how diverse mothers whose babies required a neonatal intensive care unit (NICU) stay evaluate their obstetric and neonatal care. We conducted three focus groups stratified by race/ethnicity (Black, Latina, White, and Asian women, n = 20) who delivered infants at <32 weeks gestation or <1500 g with a NICU stay. We asked women to assess perinatal care and applied classic qualitative analysis techniques to identify themes and make comparisons across groups. Predominant themes were similar across groups, including thoroughness and consistency of clinician communication, provider attentiveness, and barriers to closeness with infants. Care experiences were largely positive, but some suggested poorer communication and responsiveness toward Black and Latina mothers. Feeling consulted and included in infant care is critical for mothers of high-risk neonates. Further in-depth research is needed to remediate differences in hospital culture and quality that contribute to disparities in neonatal care and outcomes.

Prognosis of conventional vs. high-frequency ventilation for congenital diaphragmatic hernia: a retrospective cohort study.

Abstract: Objective To determine the appropriate initial ventilatory mode for neonatal congenital diaphragmatic hernia (CDH) by comparing patient prognosis following conventional mechanical ventilation (CMV) versus high-frequency oscillatory ventilation (HFO). Study design This multicenter retrospective cohort study was performed at 15 participating hospitals in Japan between 2011 and 2016. The 328 eligible CDH infants were classified into CMV (n = 78) and HFO groups (n = 250) to compare mortality and incidence of bronchopulmonary dysplasia (BPD). Propensity score matching was applied to reduce confounding by indication. Result While crude mortality was significantly higher in the HFO than the CMV group, adjusted odds ratio (OR) did not show significant difference in mortality between groups (OR of HFO group: 0.98, 95% confidence interval (CI): 0.57-1.67). Adjusted OR of BPD incidence showed no significant difference between groups (OR of HFO group: 1.66, 95%CI: 0.50-5.49). Conclusion Initial ventilatory mode in CDH patients, whether CMV or HFO, does not affect prognosis.

Immature control of breathing and apnea of prematurity: the known and unknown.

Abstract: This narrative review provides a broad perspective on immature control of breathing, which is universal in infants born premature. The degree of immaturity and severity of clinical symptoms are inversely correlated with gestational age. This immaturity presents as prolonged apneas with associated bradycardia or desaturation, or brief respiratory pauses, periodic breathing, and intermittent hypoxia. These manifestations are encompassed within the clinical diagnosis of apnea of prematurity, but there is no consensus on minimum criteria required for diagnosis. Common treatment strategies include caffeine and noninvasive respiratory support, but other therapies have also been advocated with varying effectiveness. There is considerable variability in when and how to initiate and discontinue treatment. There are significant knowledge gaps regarding effective strategies to quantify the severity of clinical manifestations of immature breathing, which prevent us from better understanding the long-term potential adverse outcomes, including neurodevelopment and sudden unexpected infant death.

Racial and ethnic disparities in outcomes through 1 year of life in infants born prematurely: a population based study in California

Abstract: Objectives To investigate racial/ethnic differences in rehospitalization and mortality rates among premature infants over the first year of life. Study design A retrospective cohort study of infants born in California from 2011 to 2017 (n = 3,448,707) abstracted from a California Office of Statewide Health Planning and Development database. Unadjusted Kaplan-Meier tables and logistic regression controlling for health and sociodemographic characteristics were used to predict outcomes by race/ethnicity. Results Compared to White infants, Hispanic and Black early preterm infants were more likely to be readmitted; Black late/moderate preterm (LMPT) infants were more likely to be readmitted and to die after discharge; Hispanic and Black early preterm infants with BPD were more likely to be readmitted; Black LMPT infants with RDS were more likely to be readmitted and die after discharge. Conclusions Racial/ethnic disparities in readmission and mortality rates exist for premature infants across several co-morbidities. Future studies are needed to improve equitability of outcomes.

The impact of maternal obesity on childhood neurodevelopment

Abstract: There is growing clinical and experimental evidence to suggest that maternal obesity increases children's susceptibility to neurodevelopmental and neuropsychiatric disorders. Given the worldwide obesity epidemic, it is crucial that we acquire a thorough understanding of the available evidence, identify gaps in knowledge, and develop an agenda for intervention. This review synthesizes human and animal studies investigating the association between maternal obesity and offspring brain health. It also highlights key mechanisms underlying these effects, including maternal and fetal inflammation, alterations to the microbiome, epigenetic modifications of neurotrophic genes, and impaired dopaminergic and serotonergic signaling. Lastly, this review highlights several proposed interventions and priorities for future investigation.

Hemodynamic and clinical consequences of early versus delayed closure of patent ductus arteriosus in extremely low birth weight infants.

Abstract: To describe changes in hemodynamics, respiratory support, and growth associated with transcatheter PDA closure (TCPC) in ELBW infants, stratified by postnatal age at treatment. This is an observational study of ELBW infants who underwent TCPC at ≤4 weeks (Group-1; n = 34), 4–8 weeks (Group-2; n = 33), and >8 weeks of age (Group-3; n = 33). Hemodynamic assessment was performed during TCPC. Multivariate Cox-proportionate-hazard modeling was used to identify factors associated with respiratory severity score (RSS) > 2 for >30 days following TCPC. In comparison with Group-1, Group-3 infants had higher pulmonary vascular resistance (PVRi = 3.3 vs. 1.6 WU*m2; P = 0.01), less weight gain between 4 and 8 weeks of age (16 vs. 25 g/day) and took longer to achieve RSS 2 for >30 days was associated with TCPC > 8 weeks (OR = 3.2, 95% CI: 1.75–5.8; p = 0.03) and PVRi ≥ 3 (OR = 4.5, 95% CI: 2.7–8.9; p < 0.01). ELBW infants may benefit from PDA closure within the first 4 weeks of life in order to prevent early onset pulmonary vascular disease, promote faster growth, and for quicker weaning of ventilator and oxygen support.

Delivery-based criteria for empiric antibiotic administration among preterm infants

Abstract: Determine impact of using delivery criteria to initiate antibiotics among very low birth weight (VLBW) and extremely low birth weight (ELBW) infants. Single site cohort study from 01/01/2009 to 01/31/2020. After 04/2017, infants delivered by Cesarean section, without labor or membrane rupture were categorized as low-risk for early-onset infection and managed without empiric antibiotics. We determined effect of this guideline by pre-post, and interrupted time-series analyses. After 04/2017, antibiotic initiation ≤3 days decreased among low-risk VLBW (62% vs. 13%, p < 0.001) and low-risk ELBW (88% vs. 21%, p < 0.001) infants. In time series analysis, guideline was associated with decreased initiation among low-risk ELBW infants. In contrast, low-risk VLBW infants demonstrated decreased antibiotic initiation throughout study period. Incidence of confirmed infection, death, or transfer ≤7 days age was unchanged. Delivery criteria may be used to optimize early antibiotic initiation among preterm infants without short-term increase in adverse outcomes.

Maternal and neonatal health care worker well-being and patient safety climate amid the COVID-19 pandemic.

Abstract: OBJECTIVE: To assess maternal and neonatal healthcare workers (HCWs) perspectives on well-being and patient safety amid the COVID-19 pandemic. STUDY DESIGN: Anonymous survey of HCW well-being, burnout, and patient safety over the prior conducted in June 2020. Results were analyzed by job position and burnout status. RESULT: We analyzed 288 fully completed surveys. In total, 66% of respondents reported symptoms of burnout and 73% felt burnout among their co-workers had significantly increased. Workplace strategies to address HCW well-being were judged by 34% as sufficient. HCWs who were "burned out" reported significantly worse well-being and patient safety attributes. Compared to physicians, nurses reported higher rates of unprofessional behavior (37% vs. 14%, p = 0.027) and difficulty focusing on work (59% vs. 36%, p = 0.013). CONCLUSION: Three months into the COVID-19 pandemic, HCW well-being was substantially compromised, with negative ramifications for patient safety.

Improving the quality of neonatal acute kidney injury care: neonatal-specific response to the 22nd Acute Disease Quality Initiative (ADQI) conference.

Abstract: With the adoption of standardized neonatal acute kidney injury (AKI) definitions over the past decade and the concomitant surge in research studies, the epidemiology of and risk factors for neonatal AKI have become much better understood. Thus, there is now a need to focus on strategies designed to improve AKI care processes with the goal of reducing the morbidity and mortality associated with neonatal AKI. The 22nd Acute Dialysis/Disease Quality Improvement (ADQI) report provides a framework for such quality improvement in adults at risk for AKI and its sequelae. While many of the concepts can be translated to neonates, there are a number of specific nuances which differ in neonatal AKI care. A group of experts in pediatric nephrology and neonatology came together to provide neonatal-specific responses to each of the 22nd ADQI consensus statements.

Changing safety culture

Abstract: Safety culture, an aspect of organizational culture, that reflects work place norms toward safety, is foundational to high-quality care. Improvements in safety culture are associated with improved operational and clinical outcomes. In the neonatal intensive care unit (NICU), where fragile infants receive complex, coordinated care over prolonged time periods, it is critically important that unit norms reflect the high priority placed on safety. Changing the safety culture of the NICU involves a systematic process of measurement, identifying strengths and weaknesses, deploying targeted interventions, and learning from the results, to set the stage for an iterative process of improvement. Successful change efforts require: effective partnerships with key stakeholders including management, clinicians, staff, and families; using data to make the case for improvement; and leadership actions that motivate change, channel resources, and support active problem- solving. Sustainable change requires buy-in from NICU staff and management, resources, and long-term institutional commitment.

Critical decision-making in neonatology and pediatrics: the I-P-O framework

Abstract: Critical decision-making in neonatology and other areas of pediatrics often carries with it a complex and difficult ethical component. For any treatment under consideration, the impermissible-permissible-obligatory (I-P-O) spectrum provides a useful framework for determining how to proceed. Any proposed treatment can be located along this spectrum, and identified as either ethically impermissible, permissible, or obligatory. Treatments determined to be ethically impermissible should not be made available by physicians. Those deemed ethically permissible should be explained to parents, commonly with a specific recommendation. Informed parents should then be free to choose from among permissible options. Potential treatments deemed ethically obligatory should be provided to the patient, even in the face of parental objection. The fundamental ethical work in neonatology and pediatrics is determining where on the I-P-O spectrum a treatment under consideration should be located. This should be determined by the prognosis for the patient with and without the treatment, the feasibility of providing the treatment, and consideration of all relevant rights and obligations. Location on the line is dynamic, and clinicians should be open to movement of a given treatment along the spectrum as new information, particularly regarding effectiveness, toxicity, and/or alternatives, becomes available. This framework provides a structure for ethical conversation and decision-making related to a specific patient, as well as in the formation of institutional and national guidelines.

Previous viral symptoms and individual mothers influenced the leveled duration of human milk antibodies cross-reactive to S1 and S2 subunits from SARS-CoV-2, HCoV-229E, and HCoV-OC43.

Abstract: The influence of previous viral symptoms on the level and duration of human milk antibodies reactive to SARS-CoV-2, and common human coronaviruses (HCoVs) was investigated. Antibodies reactive to S1 and S2 subunits from SARS-CoV-2, HCoV-OC43, and HCoV-229E were measured via ELISA in human milk samples collected from March to June 2020 in mothers with and without viral symptoms. The presence of viral symptoms influenced the levels of SARS-CoV-2 S2-reactive SIgA/IgA and tended to influence SARS-CoV-2 S1 SIgA/IgA and S2-reactive SIgM/IgM in human milk but did not relate to IgG. HCoV-229E S1 + S2-reactive SIgA/IgA and SIgM/IgM, as well as HCoV-OC43 S1 + S2-reactive IgG were related to the symptoms. The duration of antibody levels in human milk in mothers with viral symptoms varied between 3 and 4 months post maternal report of viral symptoms. Previous viral symptoms and individual mothers may change the antibody cross-reactive levels to SARS-CoV-2 and HCoVs in human milk.

Titers of SARS CoV-2 antibodies in cord blood of neonates whose mothers contracted SARS CoV-2 (COVID-19) during pregnancy and in those whose mothers were vaccinated with mRNA to SARS CoV-2 during pregnancy.

Abstract: OBJECTIVE: We compared neonatal immunity after vaccination against SARS-CoV-2 during pregnancy to that achieved after maternal infection. STUDY DESIGN: We tested cord blood from women infected with SARS-CoV-2 during pregnancy (group 1, n = 29), women who were vaccinated during pregnancy (group 2, n = 29) and from women not infected and not vaccinated (Group 3, n = 21) for titers of antibodies to both SARS-CoV-2 spike and 'N' proteins. RESULTS: Seventy-nine women were included: Antibodies against SARS-CoV-2 spike protein were detected in all samples from Group 1 and 2. Antibodies to the 'N' protein were detected in 25/29 samples in Group 1. None of the samples from Group 3 had antibodies to either protein. Mean titers of SARS-CoV-2 antibodies were significantly higher in Group 2 than in Group 1 (p < 0.05). CONCLUSIONS: Neonates born to mothers vaccinated during pregnancy have higher antibody titers and may therefore have more prolonged protection than those born to women infected during pregnancy.

Diverse perspectives on death, disability, and quality of life: an exploratory study of racial differences in periviable decision-making

Abstract: To qualitatively explore perceptions of pain/suffering, disability, and coping by race among pregnant women facing the threat of a periviable delivery (22 0/7–24 6/7 weeks). Interviews were conducted in-hospital prior to delivery. Transcripts were coded verbatim and responses were stratified by race (white vs non-white). Conventional content analysis was conducted using NVivo 12. We recruited 30 women (50% white, 50% non-white). Most women expressed love and acceptance of their babies and described pain as a “means to an end.” Non-white women focused almost exclusively on immediate survival and perseverance, while white women expressed concerns about quality of life beyond the NICU. The majority of non-white women were unable to recall any discussions with their doctors about their baby’s comfort, pain, or suffering. These findings may suggest that culturally tailored approaches to counseling and decision-support may be beneficial for patients from marginalized or minoritized groups.

Invasive mechanical ventilation at 36 weeks post-menstrual age, adverse outcomes with a comparison of recent definitions of bronchopulmonary dysplasia

Abstract: To determine whether the need for invasive mechanical ventilation (iMV) at 36 weeks PMA in patients with severe bronchopulmonary dysplasia (sBPD) identifies those patients at highest risk for tracheostomy or gastrostomy, and to compare sBPD with recent definitions of BPD. Observational study from Jan 2015 to Sept 2019 using data from the BPD Collaborative Registry. Five hundred and sixty-four patients with sBPD of whom 24% were on iMV at 36 weeks PMA. Those on iMV had significantly (p < 0.0001) increased risk for tracheostomy or gastrostomy. The overall mortality rate was 3% and the risk for mortality was substantially greater in those on iMV than in those on noninvasive support at 36 weeks PMA (RR 13.8, 95% CI 4.3–44.5, p < 0.0001). When applying the NICHD definition (2016) 44% had Grade III BPD. When applying the NRN definition, 6% had Grade 1 BPD, 70% had Grade 2 BPD, and 24% had Grade 3 BPD. Patients with sBPD who were on iMV at 36 weeks had a significantly greater risk of inhospital mortality and survivors had a significantly greater risk of undergoing tracheostomy and/or gastrostomy. The use of type 2 sBPD or Grade 3 BPD would enhance the ability to target future studies to those infants with sBPD at the highest risk of adverse long-term outcomes.

Weight, length, and head circumference at 36 weeks are not predictive of later cognitive impairment in very preterm infants

Abstract: OBJECTIVE To assess diagnostic accuracy of 36-week anthropometric weight, length, and head circumference <10th and <3rd percentiles to predict preterm infant cognitive impairment. STUDY DESIGN Cohort study of 898 preterm <30-week very-low-birth weight (<1500 g) infants. Anthropometric measures' accuracy to predict cognitive impairment (Bayley-III Cognitive Composite score) <80, 21-months corrected age (CA) and Wechsler Preschool and Primary Scale of Intelligence Quotient (intellectual outcomes) <70, 36-months CA, were determined using receiver operating characteristic (ROC) curves. RESULT Thirty-six-week weight, length or head circumference <10th or <3rd percentile did not predict cognitive impairment; areas under ROC curves were <0.6. Sensitivities and specificities for 10th and 3rd percentile cut points were all poor, with most not exceeding 70%, whether the Fenton 2013 or INTERGROWTH 2015 growth charts were used. Brain injury and low maternal education were better predictors of cognitive impairment. CONCLUSION Preterm infant 36-week anthropometric measurements are not accurate predictors of cognitive impairment.

A randomized trial of intravenous acetaminophen versus indomethacin for treatment of hemodynamically significant PDAs in VLBW infants

Abstract: Objective was to compare the rate of successful treatment of hsPDA based on echocardiogram criteria after use of IV acetaminophen or IV indomethacin in very low-birthweight infants. The study was a multi-center, randomized controlled trial. Infants born prior to 32 weeks with birthweight ≤ 1500 g were included if PDA treatment was indicated within the 21 days after birth. hsPDA was defined by strict echocardiogram criteria. Eligible infants were randomized to treatment with either IV acetaminophen or IV indomethacin. Of 86 eligible infants, 17 infants were randomized to acetaminophen and 20 to indomethacin. One (5.9%) hsPDA in the acetaminophen group had successful treatment compared to 11 (55%) in the indomethacin group (p = 0.002). Eight (47%) in the acetaminophen group and 3 (15%) in the indomethacin group received transcatheter PDA closure (p = 0.07). IV indomethacin was more effective than IV acetaminophen for treatment of hsPDAs. More infants in the acetaminophen group received transcatheter closure.

Neonatal lymphatic flow disorders: impact of lymphatic imaging and interventions on outcomes.

Abstract: Neonatal chylothorax (NCTx) and central lymphatic flow disorder (CLFD) are historically challenging neonatal disorders with high morbidity and mortality. METHODS We conducted a retrospective study of 35 neonates with pulmonary lymphatic abnormalities at our institution who underwent lymphatic evaluation between December 2015 and September 2018. Patients with only pulmonary lymphatic perfusion syndrome were classified as NCTx and those with multiple flow abnormalities were classified as CLFD. Demographics, clinical characteristics, and outcomes were compared using t-tests/Wilcoxon rank sum tests and Fisher's exact tests. RESULTS All 35 patients had intranodal MR lymphangiography and 14 (40%) also had conventional fluoroscopic lymphangiography. Fifteen (42.8%) patients were diagnosed with NCTx and 20 (57.1%) were diagnosed with CLFD. Thirty-four (97.1%) patients had pleural effusions. None of the NCTx group had ascites, anasarca, or dermal backflow compared to 17 (85%) (p < 0.001), 8 (42.1%) (p: 0.004), and 20 (100%) (p < 0.001) of the CLFD group, respectively. In the NCTx group, 11 (73.3%) had ethiodized oil embolization and 4 (26.7%) received conservative therapy. Ten (50%) of the CLFD patients had an intervention; of those, two (10%) had ethiodized oil-only embolization. Eight had non-ethiodized oil embolizations (two (25%) had embolization with glue, three (37.5%) underwent surgical lymphovenous anastomosis, two (25%) underwent thoracic duct (TD) externalization, and one (12.5%) had a non-TD lymphatic channel drain placed). Complete resolution of pleural effusions was achieved in all 15 NCTx patients, whereas 9 (45%) of 20 CLFD patients had resolution of chylothorax (p: 0.001). CONCLUSIONS Establishing a diagnosis of NCTx or CLFD is paramount in selecting treatment options and providing prognostic information. Development of lymphatic interventions represents a paradigm shift in our understanding of neonatal lymphatic flow disorders and may be associated with improved survival.

Neonatal family-centered care in a pandemic.

Abstract: Family-centered care (FCC) has become the normative practice in Neonatal ICUs across North America. Over the past 25 years, it has grown to impact clinician-parent collaborations broadly within children's hospitals as well as in the NICU and shaped their very culture. In the current COVID-19 pandemic, the gains made over the past decades have been challenged by "visitor" policies that have been implemented, making it difficult in many instances for more than one parent to be present and truly incorporated as members of their baby's team. Difficult access, interrupted bonding, and confusing messaging and information about what to expect for their newborn can still cause them stress. Similarly, NICU staff have experienced moral distress. In this perspective piece, we review those characteristics of FCC that have been disrupted or lost, and the many facets of rebuilding that are presently required.
