RESUMEN
OBJECTIVE: To characterize the presentation and evaluation of infants with neonatal encephalopathy (NE) not due to hypoxic-ischemic encephalopathy (non-HIE NE) and to describe the genetic abnormalities identified. STUDY DESIGN: Retrospective cohort study of 193 non-HIE NE neonates admitted to a level IV NICU from 2015 through 2019. For changes in testing over time, Cochrane-Armitage test for trend was used with a Bonferroni-corrected P-value, and comparison between groups was performed using Fisher exact test. RESULT: The most common symptom of non-HIE NE was abnormal tone in 47% (90/193). Ten percent (19/193) died prior to discharge, and 48% of survivors (83/174) required medical equipment at discharge. Forty percent (77/193) underwent genetic testing as an inpatient. Of 52 chromosomal studies, 54 targeted tests, and 16 exome sequences, 10%, 41%, and 69% were diagnostic, respectively, with no difference in diagnostic rates between infants with and without an associated congenital anomaly and/or dysmorphic feature. Twenty-eight genetic diagnoses were identified. CONCLUSIONS: Neonates with non-HIE NE have high rates of morbidity and mortality and may benefit from early genetic testing, even in the absence of other exam findings. This study broadens our knowledge of genetic conditions underlying non-HIE NE, which may enable families and care teams to anticipate the needs of the individual, allow early initiation of targeted therapies, and facilitate decisions surrounding goals of care.

BACKGROUND AND OBJECTIVES: Pediatric residents are at high risk for moral distress, knowing the moral or ethically right thing to do but feeling unable to do it, which is associated with poor patient care and burnout. Researchers have proposed numerous interventions to reduce distress, but few (if any) have been supported by experimental evidence. In this study, we used an experimental method to provide proof-of-concept evidence regarding the effect of various simple supports on pediatric residents' reported degree of moral distress. METHODS: We conducted a study of pediatric residents using a split sample experimental design. The questionnaire contained 6 clinical vignettes describing scenarios expected to cause moral distress. For each case, participants were randomly assigned to see 1 of 2 versions that varied only regarding whether they included a supportive statement. After reading each of the 6 cases, participants reported their level of associated moral distress. RESULTS: Two hundred and twenty respondents from 5 residency programs completed the experiment. Cases were perceived to represent common scenarios that cause distress for pediatric residents. The addition of a supportive statement reduced moral distress in 4 of the 6 cases. CONCLUSIONS: In this proof-of-concept study, simple yet effective interventions provided support by offering the resident empathy and shared perspective or responsibility. Interventions that were purely informational were not effective in reducing moral distress.

OBJECTIVE: To assess which potential future outcomes are most important to parents of children with bronchopulmonary dysplasia, a disease that affects future respiratory, medical, and developmental outcomes for children born preterm. STUDY DESIGN: We recruited parents from 2 children's hospitals' neonatal follow-up clinics and elicited their importance rating for 20 different potential future outcomes associated with bronchopulmonary dysplasia. These outcomes were identified and selected through a literature review and discussions with panels of parents and clinician stakeholders, via a discrete choice experiment. RESULTS: One hundred and 5 parents participated. Overall, parents ranked "Will my child be more vulnerable to other problems because of having lung disease?" as the most important outcome, with other respiratory health related outcomes also highly ranked. Outcomes related to child development and effects on the family were among the lowest ranked. Individually, parents rated outcomes differently, resulting in a broad distribution of importance scores for many of the outcomes. CONCLUSIONS: The overall rankings suggest that parents prioritize future outcomes related to physical health and safety. Notably, for guiding research, some top-rated outcomes are not traditionally measured in outcome studies. For guiding individual counseling, the broad distribution of importance scores for many outcomes highlights the extent to which parents differ in their prioritization of outcomes.

Research on how physicians predict and communicate prognosis focuses primarily on end-of-life care. Unsurprisingly, as genomic technology gains traction as a prognostic tool, the focus has also been on terminality, with research focused on how genetic results may be used to terminate pregnancies or redirect care towards palliation for neonates. However, genomic results also have powerful impacts on how patients who live prepare for their futures. Genomic testing provides broad-reaching and early-albeit complex, uncertain, and shifting-prognostic information. In this essay, we argue that as genomic testing occurs earlier and increasingly in a screening context, researchers and clinicians must strive to understand and manage the prognostic implications of results. While our understanding of the psychosocial and communicational aspects of prognosis in symptomatic populations is incomplete, it has progressed further than our understanding in a screening context and therefore provides useful lessons and feasible opportunities for further research. By providing an interdisciplinary and inter-specialty perspective on the psychosocial and communicational aspects of prognosis in genetics, we discuss prognostication with respect to genetics from the neonatal period through adulthood, highlighting medical specialties and patient populations that are especially informative for considering the longitudinal management of prognostic information in genomic medicine.
RESUMEN
PURPOSE: This study aimed to examine variation in genetic testing between neonatal intensive care units (NICUs) across hospitals over time. METHODS: We performed a multicenter large-scale retrospective cohort study using NICU discharge data from the Pediatric Hospital Information System database between 2016 and 2021. We analyzed the variation in the percentage of NICU patients who had any genetic testing across hospitals and over time. We used a multivariable multilevel logistic regression model to investigate the potential association between patient characteristics and genetic testing. RESULTS: The final analysis included 207,228 neonates from 38 hospitals. Overall, 13% of patients had at least 1 genetic test sent, although this varied from 4% to 50% across hospitals. Over the study period, the proportion of patients tested increased, with the increase disproportionately borne by hospitals already testing high proportions of patients. On average, patients who received genetic testing had higher illness severity. Controlling for severity, however, only minimally reduced the degree of hospital-level variation in genetic testing. CONCLUSION: The percentage of NICU patients who undergo genetic testing varies among hospitals and increasingly so over time. Variation is largely unexplained by differences in severity between hospitals. The degree of variation suggests that clearer guidelines for NICU genetic testing are warranted.

Importance: Genomic medicine holds promise to revolutionize care for critically ill infants by tailoring treatments for patients and providing additional prognostic information to families. However, measuring the utility of genomic medicine is not straightforward and has important clinical and ethical implications. Objective: To review the ways that researchers measure or neglect to measure the utility of genomic medicine for critically ill infants. Evidence Review: This systematic review included prospective full-text studies of genomic medicine of both whole exome and genome sequencing in critically ill infants younger than 1 year. PubMed, Embase, Scopus, and Cochrane Library databases, the Cochrane Database of Systematic Reviews, and the ClinicalTrials.gov register were searched with an English language restriction for articles published from the inception of each database through May 2022. Search terms included variations of the following: gene, sequencing, intensive care, critical care, and infant. From the included articles, information on how utility was defined and measured was extracted and synthesized. Information was also extracted from patient cases that authors highlighted by providing additional information. Spearman rank-order correlation was used to evaluate the association between study size and utility. Findings: Synthesized data from the 21 included studies reflected results from 1654 patients. A mean of 46% (range, 15%-72%) of patients had a positive genetic test result, and a mean of 37% (range, 13%-61%) met the criteria for experiencing utility. Despite heterogeneity in how studies measured and reported utility, a standardized framework was created with 5 categories of utility: treatment change, redirection of care, prognostic information, reproductive information, and screening or subspecialty referral. Most studies omitted important categories of utility, notably personal utility (patient-reported benefits) (20 studies [95%]), utility of negative or uncertain results (15 [71%]), and disutility (harms) (20 [95%]). Studies disproportionally highlighted patient cases that resulted in treatment change. Larger studies reported substantially lower utility (r = -0.65; P = .002). Conclusions and Relevance: This systematic review found that genomic medicine offered various categories of utility for a substantial proportion of critically ill infants. Studies measured utility in heterogeneous ways and focused more on documenting change than assessing meaningful benefit. Authors' decisions about which cases to highlight suggest that some categories of utility may be more important than others. A more complete definition of utility that is used consistently may improve understanding of potential benefits and harms of genetic medicine.

BACKGROUND AND OBJECTIVES: Genetic testing is expanding among ill neonates, yet the influence of genetic results on medical decision-making is not clear. With this study, we sought to determine how different types of genetic information with uncertain implications for prognosis influence clinicians' decisions to recommend intensive versus palliative care. METHODS: We conducted a national study of neonatologists using a split sample experimental design. The questionnaire contained 4 clinical vignettes. Participants were randomly assigned to see one of 2 versions that varied only regarding whether they included the following genetic findings: (1) a variant of uncertain significance; (2) a genetic diagnosis that affects neurodevelopment but not acute survival; (3) a genetic versus nongenetic etiology of equally severe pathology; (4) a pending genetic testing result. Physicians answered questions about recommendations they would make for the patient described in each vignette. RESULTS: Vignette versions that included a variant of uncertain significance, a diagnosis foreshadowing neurodevelopmental impairment, or a genetic etiology of disease were all associated with an increased likelihood of recommending palliative rather than intensive care. A pending genetic test result did not have a significant effect on care recommendations. CONCLUSIONS: Findings from this study of hypothetical cases suggest neonatologists apply uncertain genetic findings or those that herald neurodevelopmental disability in problematic ways. As genetic testing expands, understanding how it is used in decision-making and educating clinicians regarding appropriate use are paramount.

Tyrosinemia type 1 (TT1) is an inborn error of tyrosine metabolism with features including liver dysfunction, cirrhosis, and hepatocellular carcinoma; renal dysfunction that may lead to failure to thrive and bone disease; and porphyric crises. Once fatal in most infantile-onset cases, pre-symptomatic diagnosis through newborn screening (NBS) protocols, dietary management, and pharmacotherapy with nitisinone have improved outcomes. Succinylacetone provides a sensitive and specific marker for the detection of TT1 but is not universally utilized in screening protocols for the disease. Here, we report an infant transferred to our facility for evaluation and management of hyperinsulinism who subsequently developed acute-onset liver, respiratory, and renal failure around one month of life. She was found to have TT1 caused by novel pathogenic variant in fumarylacetoacetate hydrolase (c.1014 delC, p.Cys 338 Ter). Her NBS, which utilized tyrosine as a primary marker, had been reported as normal, with a tyrosine level of 151 µmol/L (reference: < 280 µmol/L). Retrospective analysis of dried blood spot samples via tandem mass spectrometry showed detectable succinylacetone ranging 4.65-10.34 µmol/L. To our knowledge, this is the first patient with TT1 whose initial presenting symptom was hyperinsulinemic hypoglycemia. The case highlights the importance of maintaining a high suspicion for metabolic disease in critically ill children, despite normal NBS. We also use the case to advocate for NBS for TT1 using succinylacetone quantitation.
