Isolated and On Guard: Preparing Neonatal Intensive Care Unit Families for Life with Hydrocephalus.

OBJECTIVE: This study was aimed to characterize the parent experience of caring for a child with posthemorrhagic hydrocephalus and to describe parent preferences for counseling in the neonatal period and beyond. STUDY DESIGN: This was a qualitative interview study. Parents of infants born preterm with posthemorrhagic hydrocephalus completed semistructured interviews. Data were analyzed using a content analysis approach. RESULTS: Thematic saturation was reached on parent communication preferences after 10 interviews. Parent experiences of infant hydrocephalus broadly fell into two time periods, the neonatal intensive care unit (NICU) and after NICU discharge. The themes of uncertainty, isolation, hypervigilance, and the need for advocacy were common to each phase. CONCLUSION: Parents expressed interest in the development of tiered NICU counseling tools that would provide evidence-based and family-centric information to (1) initiate connections with community and peer resources and (2) combat the isolation and hypervigilance that characterized their family experience of living with hydrocephalus. KEY POINTS: · Infants with posthemorrhagic hydrocephalus are at risk for adverse neurodevelopmental outcomes.. · The parent experience of caring for a child with posthemorrhagic hydrocephalus is not well-described. In this interview study, parents described uncertainty, isolation, and hypervigilance.. · These findings call for structured NICU counseling and longitudinal family supports after discharge..

Parent preferences for neurodevelopmental screening in the neonatal intensive care unit.

AIM: To determine whether, and how, neonatal intensive care unit (NICU) parents want to receive early neurodevelopmental screening information about their child's future risk of cerebral palsy and other disabilities. METHOD: This was a qualitative interview study. Parents of hospitalized infants born preterm completed semi-structured interviews. Data were analysed using a directed content analysis approach. RESULTS: Thematic saturation was achieved after 19 interviews. Four themes characterized parent perceptions of early neurodevelopmental screening: (1) acceptability: most parents were in favour of neurodevelopmental screening if parents could refuse; (2) disclosure of results: parents want emotional preparation for results, especially false positives; (3) emotional burden of uncertainty: parents of children in the NICU balance taking their infant's illness 'day by day' and preparing for an uncertain future. Parents expressed distress with screening that increased uncertainty about the future; and (4) disability: prior experience with disability informs parent concerns. INTERPRETATION: Parents interpret the risks and benefits of NICU developmental screening through the lens of prior experiences with disability. Most expressed interest in screening and emphasized a desire for autonomy, pretest counselling, and emotional preparation. WHAT THIS PAPER ADDS: Most parents with infants in the neonatal intensive care unit expressed interest in early screening for developmental disability. Prior experience with disability informed concerns about specific deficits. Parents emphasized a desire for autonomy, pretest counselling, and emotional preparation.

Early Preterm Birth Across Generations Among Whites and African-Americans: A Population-Based Study.

Objectives To determine the extent to which non-Latina White and African-American mother's gestational age is associated with extremely early (<30 weeks), modestly early (30-33 weeks), and late (34-36 weeks) infant preterm birth (PTB) rates. Methods Race-specific stratified and multivariable logistic regression analyses were performed on the Illinois Transgenerational Birth File of non-Latino White and African-American infants (born 1989-1991) and their mothers (born 1956-1976). Results White mothers (n = 184) born at <30 weeks had a greater extremely early infant PTB rate than White mothers (n = 131,980) born at term: 1.6 versus 0.5%, respectively; RR = 3.6 (1.2, 11.0). African-American mothers (n = 269) born at <30 weeks had a greater extremely early infant PTB rate than African-American mothers (n = 34,885) born at term: 4.1 versus 2.1%, respectively; RR = 2.0 (1.1, 3.6). In logistic regression models the adjusted (controlling for maternal age, education, parity, prenatal care, marital status, and cigarette smoking) OR of extremely early PTB for White and African-American mothers born <30 (compared to ≥37) weeks equaled 4.0 (1.2, 12.6) and 2.3 (1.2, 4.3), respectively. The adjusted OR of modestly early PTB for White and African-American mothers born 30-33 (compared to ≥37) weeks equaled 1.6 (1.0, 2.5) and 1.3 (0.9, 1.7), respectively. The adjusted OR of late PTB for White and African-American mothers born 34-36 (compared to ≥37) weeks equaled 1.2 (1.0, 1.3) and 1.1 (1.0, 1.2), respectively. Conclusions A generational association of extremely early, but not modestly early or late, PTB exists among non-Latino Whites and African-Americans.

Application of desirability of outcome ranking to the milking in non-vigorous infants trial.

OBJECTIVES: Neonatal trials have traditionally used binary composite short-term (such as death or bronchopulmonary dysplasia) or longer-term (such as death or severe neurodevelopmental impairment) outcomes. We applied the Desirability Of Outcome Ranking (DOOR) method to rank the overall patient outcome by best (no morbidities) to worst (death). STUDY DESIGN: Using a completed large multicenter trial (Milking In Non-Vigorous Infants [MINVI]) of umbilical cord milking (UCM) vs. early cord clamping (ECC), we applied the DOOR methodology to neonatal outcomes. Six outcomes were chosen and ranked: no interventions or NICU admission (most desirable); received initial cardiorespiratory support at birth; neonatal intensive care unit (NICU) admission for predefined criteria; mild hypoxic-ischemic encephalopathy (HIE); moderate to severe HIE; and death (least desirable). RESULTS: 1524 non-vigorous newborns born between 35 and 42 weeks' gestation had data for analysis. The DOOR distribution was different between the UCM and ECC arms, with a significantly greater probability (55.8 % [95 % CI 53.1-58.5 %; p < 0.0001]) of a randomly selected neonate having a more desirable outcome if they were in the UCM arm. DOOR probabilities of averting individual adverse outcomes such as NICU admission for predefined criteria (52.8 %; 95%CI 50.5-55.1 %) and cardiorespiratory support (54.0 %; 95%CI 51.6-56.4 %) were significantly higher among those in the UCM group. CONCLUSION: DOOR provides an overall assessment of the benefits and harms with greater insight than typical binary composite measures to clinicians and parents when evaluating an intervention. Future neonatal trials should consider the a priori use of the DOOR methodology to evaluate trial outcomes.

Parental perspectives on a trial using waived informed consent at birth.

OBJECTIVES: To determine parental perspectives in a trial with waived consent. STUDY DESIGN: Anonymous survey of birth parents with term infants who were randomized using a waiver of consent, administered after infant discharge. RESULTS: 121 (11%) survey responses were collected. Of the 121 responding parents 111 (92%) reported that this form of consent was acceptable and 116 (96%) reported feeling comfortable having another child participate in a similar study. 110 (91%) respondents reported that they both understood the information provided in the consent process and had enough time to consider participation. Four percent had a negative opinion on the study's effect on their child's health. CONCLUSIONS: Most responding parents reported both acceptability of this study design in the neonatal period and that the study had a positive effect on their child's health. Future work should investigate additional ways to involve parents and elicit feedback on varied methods of pediatric consent.

Optimizing transition: Providing oxygen during intact cord resuscitation.

Delayed clamping and cutting of the umbilical cord at birth is standard practice for management for all newborns. Preterm infants may additionally benefit from a combination of ventilation and oxygen provision during intact cord resuscitation. This review highlights both the potential benefits of such a combined approach and the need for further rigorous studies, including randomized controlled trials, of delivery room management in this population.

Symptoms of Cerebrospinal Shunt Malfunction in Young Children: A National Caregiver Survey.

Objective: This study aimed to describe shunt malfunction symptoms in children ≤5 years old. Results: In a national survey of 228 caregivers, vomiting (23.1%), irritability (20.8%), and sleepiness (17.2%) were the most frequent symptoms of malfunction. These symptoms also occurred in over 1/3 of "false alarms" experienced by 75% of respondents. Compared with malfunctions, irritability (OR = 1.39, 95% CI [1.05, 1.85], p = 0.022) and fever (OR = 2.22, 95% CI [1.44, 3.44], p < 0.001) were more likely false alarms. Caregivers counseled about "most" symptoms were more confident detecting malfunctions than those informed of "some" (p = 0.036). The majority of caregivers (85%) first contacted a neurosurgeon with concerns about malfunction, followed by neurologists (22%) and family/friends (19%). Most (85%) struggled to differentiate malfunction from regular development. Conclusions: Vomiting, irritability, and sleepiness were the most common symptoms of shunt malfunction and false alarms for children ≤5 years. Most caregivers reported challenges differentiating malfunctions from their child's development.

Life on the Frontlines: Caregiver Experience of Pediatric Cerebrospinal Shunt Malfunction.

BACKGROUND: We aimed to characterize the caregiver experience in the detection and evaluation of pediatric cerebrospinal shunt malfunction. METHODS: In this descriptive qualitative study, we recruited English-speaking caregivers of children aged five years or less in collaboration with a stakeholder organization. Semistructured interviews were completed; content targeted the caregiver experience of shunt malfunction. Interviews were audio-recorded, transcribed, and deidentified. Qualitative data were analyzed using a conventional content analysis approach. RESULTS: We enrolled 20 caregivers (n = 20 mothers). The median child age at the time of the interview was 2.8 years; about half (n = 11) were born prematurely and the majority (n = 15) had shunts placed at age less than six months. Caregiver experiences of shunt malfunction were grouped into three major themes: (1) my error could be life or death: the high stakes of shunt malfunction and the ambiguity of malfunction symptoms exacerbated baseline caregiver vigilance; (2) finding and engaging people who can help: hurdles during malfunction evaluation included locating trusted clinicians and advocating for parental intuition; and (3) how the shunt defines our family: caregivers described evolving expertise and modifications made to everyday life due to the threat of malfunction. CONCLUSIONS: In this study, caregivers highlighted the challenges associated with recognizing shunt malfunction, accessing necessary treatment, and the impact of their child's shunt on family life. Future work should leverage these findings to inform counseling about shunt malfunction, develop interventions to better support families in shunt malfunction identification, and educate medical providers.

The Relationship Between Clinical Imaging and Neurobehavioral Assessment in Posthemorrhagic Ventricular Dilation of Prematurity.

Introduction: Neonatal intraventricular hemorrhage (IVH) and subsequent posthemorrhagic ventricular dilation and hydrocephalus of prematurity are associated with brain injury and neurodevelopmental impairment in the preterm population. Neuroimaging assesses cerebral injury and guides neurosurgical intervention; however, the relationship of head ultrasound (HUS) and magnetic resonance imaging (MRI) parameters to neonatal exams in this group has not been well described. The NICU Network Neurobehavioral Scale (NNNS) is a reproducible, highly reliable battery with motor and cognitive domain scores. Objective: To evaluate the relationship between neonatal neurobehavioral findings on the NNNS and measures of ventricular dilation and associated brain injury on HUS and MRI. Materials and Methods: Neonates with IVH and ventricular dilatation with and without posthemorrhagic hydrocephalus were enrolled. NNNS exams were performed at approximately term age equivalent. HUS indices were measured on the last HUS before initial neurosurgical procedure or that with worst ventriculomegaly if no intervention. The posterior fossa was assessed with MRI at term. Descriptive statistics including medians, interquartile ranges, means, and percentages were performed. Correlations were estimated using Pearson's method. Results: 28 patients had NNNS and HUS, and 18 patients also had an MRI. Ventricle size measures for the cohort were significantly above normal. Motor and cognitive subscores on the NNNS exam varied from established baseline scores for postmenstrual age. Children who required neurosurgical intervention had higher ventricle/brain ratios and worse NNNS habituation scores. Ventricle sizes were modestly correlated with motor abnormalities (0.24-0.59); larger anterior horn width correlated with nonoptimal reflexes, hypertonicity and hypotonicity. Ventricle sizes were modestly correlated with cognitive scores (-0.44 to 0.27); larger ventricular index correlated with worse attention. Periventricular hemorrhagic infarction correlated with worse habituation. Conclusion: For this cohort of preterm infants with IVH, surgical intervention for posthemorrhagic hydrocephalus correlated with both larger degrees of ventriculomegaly and worse NNNS exams. Findings on both HUS and MRI correlated with motor and cognitive abnormalities on neonatal neurobehavioral exam, suggesting that larger neonatal ventricle sizes and white matter injury have detectable correlates on exam. The NNNS exam provides important additional information when assessing posthemorrhagic ventricular dilation and hydrocephalus of prematurity.

Early neurodevelopmental outcome in preterm posthemorrhagic ventricular dilatation and hydrocephalus: Neonatal ICU Network Neurobehavioral Scale and imaging predict 3-6-month motor quotients and Capute Scales.

OBJECTIVE: Brain injury remains a serious complication of prematurity. Almost half of infants with severe intraventricular hemorrhage (IVH) develop posthemorrhagic ventricular dilatation (PHVD) and 20% need surgery for posthemorrhagic hydrocephalus (PHH). This population is associated with an increased risk of later neurodevelopmental disability, but there is uncertainty about which radiological and examination features predict later disability. In this study the authors sought to devise and describe a novel combination of neurobehavioral examination and imaging for prediction of neurodevelopmental disability among preterm infants with PHVD and PHH. METHODS: The study patients were preterm infants (< 36 weeks gestation) with IVH and PHVD, with or without PHH. Ventricular index (VI), anterior horn width (AHW), thalamooccipital distance (TOD), ventricle/brain (V/B) ratio, and resistive indices (RIs) were recorded on the head ultrasound (HUS) just prior to surgery, or the HUS capturing the worst PHVD when surgery was not indicated. The posterior fossa was assessed with MRI. Neonatal ICU Network Neurobehavioral Scale (NNNS) examinations were performed at term age equivalent for each infant. A neurodevelopmental assessment using the Capute Scales (Capute Cognitive Adaptive Test [CAT] scores and Capute Clinical Linguistic Auditory Milestone Scale [CLAMS] scores) and a motor quotient (MQ) assessment were performed between 3 and 6 months of age corrected for degree of prematurity (corrected age). MQs < 50 reflect moderate to severe delays in early motor milestone attainment, CAT scores < 85 reflect delays in early visual and problem-solving abilities, and CLAMS scores < 85 reflect delays in early language. RESULTS: Twenty-one infants underwent assessments that included imaging and NNNS examinations, Capute Scales assessments, and MQs. NNNS nonoptimal reflexes (NOR) and hypertonicity subscores and AHW were associated with MQs < 50: NOR subscore OR 2.46 (95% CI 1.15-37.6, p = 0.034), hypertonicity subscore OR 1.68 (95% CI 1.04-3.78, p = 0.037), and AHW OR 1.13 (95% CI 1.01-1.39, p = 0.041). PVHI, cystic changes, and neurosurgical intervention were associated with CAT scores < 85: PVHI OR 9.2 (95% CI 1.2-73.2, p = 0.037); cystic changes OR 12.0 (95% CI 1.0-141.3, p = 0.048), and neurosurgical intervention OR 11.2 (95% CI 1.0-120.4, p = 0.046). Every 1-SD increase in the NOR subscore was associated with an increase in odds of a CAT score < 85, OR 4.0 (95% CI 1.0-15.0, p = 0.044). Worse NNNS NOR subscores were associated with early language delay: for a 1-SD increase in NOR subscore, there was an increase in the odds of a CLAMS score < 85, OR 19.5 (95% CI 1.3-303, p = 0.034). CONCLUSIONS: In former preterm children with severe IVH and PHVD, neonatal neurological examination findings and imaging features are associated with delays at 3-6 months in motor milestones, visual and problem-solving abilities, and language.

Preterm neuroimaging and neurodevelopmental outcome: a focus on intraventricular hemorrhage, post-hemorrhagic hydrocephalus, and associated brain injury.

Intraventricular hemorrhage in the setting of prematurity remains the most common cause of acquired hydrocephalus. Neonates with progressive post-hemorrhagic hydrocephalus are at risk for adverse neurodevelopmental outcomes. The goal of this review is to describe the distinct and often overlapping types of brain injury in the preterm neonate, with a focus on neonatal hydrocephalus, and to connect injury on imaging to neurodevelopmental outcome risk. Head ultrasound and magnetic resonance imaging findings are described separately. The current state of the literature is imprecise and we end the review with recommendations for future radiologic and neurodevelopmental research.
