Increasing Prevalence of Cerebral Palsy Among Two-Year-Old Children Born at <27 Weeks of Gestation: A Cohort Study.

OBJECTIVE: To evaluate changes in prevalence and severity of cerebral palsy (CP) among surviving children born at <27 weeks of gestation over time and to determine associations between CP and other developmental domains, functional impairment, medical morbidities, and resource use among 2-year-old children who were born extremely preterm. STUDY DESIGN: Retrospective cohort study using prospective registry data, conducted at 25 centers of the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network. Participants were children born at <27 weeks of gestation and followed at 18 through 26 months of corrected age from 2008 through 2019. Outcomes of interest were changes in prevalence of any CP and severity of CP over time and associations between CP and other neurodevelopmental outcomes, functional impairment, and medical comorbidities. Adjusted logistic, linear, multinomial logistic, and robust Poisson regression evaluated the relationships between child characteristics, CP severity, and outcomes. RESULTS: Among 6927 surviving children with complete follow-up data, 3717 (53.7%) had normal neurologic examinations, 1303 (18.8%) had CP, and the remainder had abnormal neurologic examinations not classified as CP. Adjusted rates of any CP increased each year of the study period (aOR 1.11 per year, 95% CI 1.08-1.14). Cognitive development was significantly associated with severity of CP. Children with CP were more likely to have multiple medical comorbidities, neurosensory problems, and poor growth at follow-up. CONCLUSIONS: The rate of CP among surviving children who were born extremely preterm increased from 2008 through 2019. At 18 to 26 months of corrected age, neurodevelopmental and medical comorbidities are strongly associated with all severity levels of CP.

Automated detection of abnormal general movements from pressure and positional information in hospitalized infants.

BACKGROUND: Prechtl's general movements assessment (GMA) allows visual recognition of movement patterns that, when abnormal (cramped synchronized, or CS), have very high sensitivity in predicting later neuromotor disorders; however, training requirements and subjective perceptions from some clinicians may hinder universal adoption of the GMA in the newborn period. METHODS: To address this, we used a three-phased approach to design a preliminary and clinically-oriented approach to automated CS GMA detection. 335 hospitalized infants were dually recorded on video and a pressure-sensor mat that collected time, spatial, and pressure data. Video recordings were scored by advanced GMA readers. We then conducted a series of unsupervised machine learning and supervised classification modeling with features extracted from clinician- and mat-driven datasets. Finally, the resulting algorithm was converted to a software interface. RESULTS: A classification model combining normalization, clustering, and decision tree modeling resulted in the highest sensitivity for CS movements (100%). Results were delivered via the software interface within 20 min of data recording. CONCLUSION: The combination of clinical research, machine learning, and repurposing of existing sensor mat technology produced a feasible preliminary approach to automatically detect abnormal GMA in infants while still in the NICU. Further refinements of software and algorithms are needed. IMPACT STATEMENT: Machine learning can differentiate cramped synchronized general movement patterns in the neonatal intensive care unit with good sensitivity and specificity. Increasing access to the GMA through automated detection methods may allow for earlier identification of a greater number of children at high risk for movement delay. Large studies leveraging new artificial intelligence approaches could increase the impact of such detection.

Interventions to improve executive functions in children aged 3 years and under: A systematic review.

BACKGROUND: Early executive functioning (EF) skills are foundational capabilities that predict school readiness, academic development and psychiatric risk. Early interventions enhancing these capabilities could have critical import in improving outcomes. However, to develop interventions, it is necessary to identify specific EF skills that will vary with child age. Thus, we aimed to examine the characteristics and efficacy of interventions targeting EF in infancy and early childhood up to age 3. METHODS: A comprehensive search of PubMed, Embase, CINAHL and APA PsycINFO databases was performed for studies published before December 2022. Randomized and non-randomized studies of interventions designed to improve at least one EF skill in children ≤3 years were included. EF skills included attentional control, inhibition/self-regulation, activity initiation, working memory, cognitive flexibility, planning ability, problem-solving and performance monitoring. We independently extracted data, used the revised Cochrane Risk-of-Bias tool to assess the quality of the evidence and conducted Synthesis Without Meta-analysis (SWiM). The overall quality of the evidence and the strength of recommendations was determined using elements of the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. RESULTS: Thirty-five studies met inclusion criteria (original n = 7467). Studies were highly variable in the EF skill targeted, target subject (i.e., child, parent and teacher), nature and dosage of the intervention, and timing of outcome assessment. Most interventions focused on improving impulse control and self-regulation. The overall quality of evidence was low to moderate with a high risk of bias, though six studies had low risk of bias but yielded mixed findings of efficacy. CONCLUSIONS: The relatively small number of early EF intervention studies uses such variable methods that there is currently no converging evidence of efficacy to recommend a specific intervention. Thus, findings support the need for a more systematic, targeted approach to the design and implementation of early EF interventions for target populations.

Neurodevelopmental Outcomes of Extremely Preterm Infants Fed Donor Milk or Preterm Infant Formula: A Randomized Clinical Trial.

Importance: Maternal milk feeding of extremely preterm infants during the birth hospitalization has been associated with better neurodevelopmental outcomes compared with preterm formula. For infants receiving no or minimal maternal milk, it is unknown whether donor human milk conveys similar neurodevelopmental advantages vs preterm formula. Objective: To determine if nutrient-fortified, pasteurized donor human milk improves neurodevelopmental outcomes at 22 to 26 months' corrected age compared with preterm infant formula among extremely preterm infants who received minimal maternal milk. Design, Setting, and Participants: Double-blind, randomized clinical trial conducted at 15 US academic medical centers within the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network. Infants younger than 29 weeks 0 days' gestation or with a birth weight of less than 1000 g were enrolled between September 2012 and March 2019. Intervention: Preterm formula or donor human milk feeding from randomization to 120 days of age, death, or hospital discharge. Main Outcomes and Measures: The primary outcome was the Bayley Scales of Infant and Toddler Development (BSID) cognitive score measured at 22 to 26 months' corrected age; a score of 54 (score range, 54-155; a score of ≥85 indicates no neurodevelopmental delay) was assigned to infants who died between randomization and 22 to 26 months' corrected age. The 24 secondary outcomes included BSID language and motor scores, in-hospital growth, necrotizing enterocolitis, and death. Results: Of 1965 eligible infants, 483 were randomized (239 in the donor milk group and 244 in the preterm formula group); the median gestational age was 26 weeks (IQR, 25-27 weeks), the median birth weight was 840 g (IQR, 676-986 g), and 52% were female. The birthing parent's race was self-reported as Black for 52% (247/478), White for 43% (206/478), and other for 5% (25/478). There were 54 infants who died prior to follow-up; 88% (376/429) of survivors were assessed at 22 to 26 months' corrected age. The adjusted mean BSID cognitive score was 80.7 (SD, 17.4) for the donor milk group vs 81.1 (SD, 16.7) for the preterm formula group (adjusted mean difference, -0.77 [95% CI, -3.93 to 2.39], which was not significant); the adjusted mean BSID language and motor scores also did not differ. Mortality (death prior to follow-up) was 13% (29/231) in the donor milk group vs 11% (25/233) in the preterm formula group (adjusted risk difference, -1% [95% CI, -4% to 2%]). Necrotizing enterocolitis occurred in 4.2% of infants (10/239) in the donor milk group vs 9.0% of infants (22/244) in the preterm formula group (adjusted risk difference, -5% [95% CI, -9% to -2%]). Weight gain was slower in the donor milk group (22.3 g/kg/d [95% CI, 21.3 to 23.3 g/kg/d]) compared with the preterm formula group (24.6 g/kg/d [95% CI, 23.6 to 25.6 g/kg/d]). Conclusions and Relevance: Among extremely preterm neonates fed minimal maternal milk, neurodevelopmental outcomes at 22 to 26 months' corrected age did not differ between infants fed donor milk or preterm formula. Trial Registration: ClinicalTrials.gov Identifier: NCT01534481.

Exploring Tabletop Role-Playing Games as Meaningful Occupations: A Qualitative Exploratory Study.

Tabletop roleplaying games (TRPGs) are an increasingly popular occupation but are still relatively unknown to occupational therapists. This study sought to understand the overall experience, benefits, and consequences of playing TRPGs and the relationship to other occupations. A qualitative research design with a thematic analysis was employed using semi-structured interviews with fifteen participants who had played TRPGs. Participants ranged in age from 20 to 52 years old and six identified as female, eight as male and one as nonbinary. The researchers gleaned four themes which include: (1) Social Connection and Collaboration; (2) Occupational Participation; (3) Creativity; and (4) Societal Perceptions. This research highlights aspects of the game that people enjoy, and skills developed during gameplay translate outside of the game. It suggests possible therapeutic uses of TRPGs that should be validated with future research.

Early-Life Outcomes in Relation to Social Determinants of Health for Children Born Extremely Preterm.

OBJECTIVE: To characterize the relationships between social determinants of health (SDOH) and outcomes for children born extremely preterm. STUDY DESIGN: This is a cohort study of infants born at 22-26 weeks of gestation in National Institute of Child Health and Human Development Neonatal Research Network centers (2006-2017) who survived to discharge. Infants were classified by 3 maternal SDOH: education, insurance, and race. Outcomes included postmenstrual age (PMA) at discharge, readmission, neurodevelopmental impairment (NDI), and death postdischarge. Regression analyses adjusted for center, perinatal characteristics, neonatal morbidity, ethnicity, and 2 SDOH (eg, group comparisons by education adjusted for insurance and race). RESULTS: Of 7438 children, 5442 (73%) had at least 1 risk-associated SDOH. PMA at discharge was older (adjusted mean difference 0.37 weeks, 95% CL 0.06, 0.68) and readmission more likely (aOR 1.27, 95% CL 1.12, 1.43) for infants whose mothers had public/no insurance vs private. Neither PMA at discharge nor readmission varied by education or race. NDI was twice as likely (aOR 2.36, 95% CL 1.86, 3.00) and death 5 times as likely (aOR 5.22, 95% CL 2.54, 10.73) for infants with 3 risk-associated SDOH compared with those with none. CONCLUSIONS: Children born to mothers with public/no insurance were older at discharge and more likely to be readmitted than those born to privately insured mothers. NDI and death postdischarge were more common among children exposed to multiple risk-associated SDOH at birth compared with those not exposed. Addressing disparities due to maternal education, insurance coverage, and systemic racism are potential intervention targets to improve outcomes for children born preterm.

The impact of postpartum social support on postpartum mental health outcomes during the COVID-19 pandemic.

Social support is an influential component of postpartum recovery, adjustment, and bonding, which was disrupted by social distancing recommendations related to the COVID-19 pandemic. This study reports on changes in the availability of social support for postpartum women during the pandemic, investigates how those changes may have contributed to postpartum mental health, and probes how specific types of social support buffered against poor postpartum mental health and maternal-infant bonding impairment. Participants were 833 pregnant patients receiving prenatal care in an urban USA setting and using an electronic patient portal to access self-report surveys at two time points, during pregnancy (April-July 2020) and at ~12 weeks postpartum (August 2020-March 2021). Measures included an assessment of COVID-19 pandemic-related change in social support, sources of social support, ratings of emotional and practical support, and postpartum outcomes including depression, anxiety, and maternal-infant bonding. Overall self-reported social support decreased during the pandemic. Decreased social support was associated with an increased risk of postpartum depression, postpartum anxiety, and impaired parent-infant bonding. Among women reporting low practical support, emotional support appeared to protect against clinically significant depressive symptoms and impaired bonding with the infant. Decreases in social support are associated with a risk for poor postpartum mental health outcomes and impaired maternal-infant bonding. Evaluation and promotion of social support are recommended for healthy adjustment and functioning of postpartum women and families.

Impact of COVID-19 on Infants followed after Discharge from the Neonatal Intensive Care Unit Using a Telemedicine Model.

OBJECTIVE: Coronavirus disease 2019 (COVID-19) continues to have a profound impact on infant health care and health outcomes. In this study, we aimed to characterize the social impact of the first COVID-19 lockdown on families in a neonatal follow-up program (NFP). Given the ongoing increased use of telehealth across the medicine, we also evaluated for patient-level differences in virtual visit rates to identify patients at risk of follow-up challenges. STUDY DESIGN: To assess the impact of virtual health care utilization, we conducted a retrospective cohort study to describe challenges associated with telemedicine use in this vulnerable patient population during our telemedicine epoch (March 13, 2020-July 31, 2020). We also looked for patient-level factors associated with attending NFP visits as scheduled. Finally, we summarized caregiver responses to a COVID-19 Obstacles Assessment Survey and assessed for racial disparities in these responses. RESULTS: When comparing patients who completed their virtual visit to those who did not, we found no differences by infants' sex, birthweight, gestational age at birth, or caregiver self-reported race and ethnicity. However, infants whose visits did not occur were more often discharged with equipment or covered by public insurance. Nine percent of families reported food insecurity. CONCLUSION: During the initial COVID-19 lockdown, families with infants discharged from a neonatal intensive care unit (NICU) faced significant obstacles caring for their infants and attending scheduled follow-up visits. Infants in families with lower socioeconomic status or with increased medical complexity faced increased challenges in attending virtual follow-up visits during this epoch. Given the ongoing reliance on telemedicine in health care and the need to better prepare for future epidemics/pandemics, this study offers critical information that can assist neonatal teams in bolstering transitions to home and creating stronger safety nets for their patients after discharge. KEY POINTS: · Telemedicine works well for high-risk neonatal populations.. · Infant medical complexity may be a risk factor for challenges attending neonatal follow-up visits.. · NICUs should work to prevent food insecurity postdischarge..

Service Needs of Clients Before and After Short Term Community Mental Health Case Management.

This study evaluated level of service need before and after a short-term community mental health case management intervention from the perspective of both clients and case managers. Ontario Common Assessment of Need data were used to describe client needs. McNemar's test was applied to assess differences in pre- and post- need scores. Psychological distress, company, daytime activities, and physical health were most commonly rated by clients as unmet needs at enrolment. At discharge, there was a significant change in psychological distress from the perspective of clients, and in psychological distress and daytime activities from the perspective of case managers. Statistically significant changes were observed for Total Need, Total Unmet Need and Met Need scores from the perspective of case managers. While both clients and case managers reported changes in total service needs between admission and discharge from short-term case management, clients were less likely to report a difference in needs.

The Influence of Pandemic-Related Worries During Pregnancy on Child Development at 12 Months.

The COVID-19 pandemic has been linked to increased risk for perinatal anxiety and depression among parents, as well as negative consequences for child development. Less is known about how worries arising from the pandemic during pregnancy are related to later child development, nor if resilience factors buffer negative consequences. The current study addresses this question in a prospective longitudinal design. Data was collected from a sub-study (n = 184) of a longitudinal study of pregnant individuals (total n = 1173). During pregnancy (April 17-July 8, 2020) and the early postpartum period (August 11, 2020-March 2, 2021), participants completed online surveys. At 12 months postpartum (June 17, 2021-March 23, 2022), participants completed online surveys and a virtual laboratory visit, which included parent-child interaction tasks. We found more pregnancy-specific pandemic worries were prospectively related to lower levels of child socioemotional development based on parent report (B = - 1.13, SE = .43, p = .007) and observer ratings (B = - 0.13, SE = .07, p = .045), but not to parent-reported general developmental milestones. Parental emotion regulation in the early postpartum period moderated the association between pregnancy-specific pandemic worries and child socioemotional development such that pregnancy-specific pandemic worries did not relate to worse child socioemotional development among parents with high (B = - .02, SE = .10, t = - .14, p = .89) levels of emotion regulation. Findings suggest the negative consequences of parental worry and distress during pregnancy on the early socioemotional development of children in the context of the COVID-19 pandemic. Results highlight that parental emotion regulation may represent a target for intervention to promote parental resilience and support optimized child development.

Developing a Conceptual Model for How Occupational Therapists Can Address "Wicked Problems": A Critical Review.

IMPORTANCE: Wicked problems are those that are messy and complex and have no obvious solution. Occupational therapists and their clients encounter wicked problems in all areas of practice, and therefore it is essential that they know how to address them. OBJECTIVE: To identify the key constructs involved in addressing wicked problems, discover considerations for occupational therapists, and develop a conceptual model that supports how to address these problems. DESIGN: This study had a critical review design and focused on literature from sectors such as health care, social services, policy, business, management, and leadership. It followed a traditional critical review process and extracted records from Scopus, CINAHL and Ovid databases. RESULTS: A total of 36 articles were included in the review. The results indicated that, to address wicked problems, one must first identify the problem as wicked. The key constructs identified in the literature include collaboration, leadership, perspectives, and innovation, with collaboration and leadership as the most prominent constructs. Subthemes include interdisciplinary teams and diverse perspectives, visualizing interdependencies, team communication, leadership style, leadership communication, and shared vision. CONCLUSIONS AND RELEVANCE: The key constructs identified in this review are interconnected and imperative when addressing wicked problems as depicted in the new Addressing Wicked Problems conceptual model. Occupational therapists are well suited to extend between the traditional role and be key stakeholders in addressing wicked problems by using their leadership and collaboration skills and attitudes. What This Article Adds: Collaboration, leadership, perspective, and innovation are the key constructs for addressing wicked problems. The Addressing Wicked Problems conceptual model highlights the interconnectedness of these constructs.

Clinician-reported childbirth outcomes, patient-reported childbirth trauma, and risk for postpartum depression.

Childbirth trauma is common and increases risk for postpartum depression (PPD). However, we lack brief measures to reliably identify individuals who experience childbirth trauma and who may be at greater prospective risk for PPD. To address this gap, we used data from a racially diverse prospective cohort (n=1082). We collected survey data during pregnancy and at 12 weeks postpartum, as well as clinician-reported data from medical records. A new three-item measure of patient-reported childbirth trauma was a robust and independent risk factor for PPD, above and beyond other known risk factors for PPD, including prenatal anxiety and depression. Cesarean birth, greater blood loss, and preterm birth were each associated with greater patient-reported childbirth trauma. Finally, there were prospective indirect pathways whereby cesarean birth and higher blood loss were related to higher patient-reported childbirth trauma, in turn predicting greater risk for PPD. Early universal postpartum screening for childbirth trauma, targeted attention to individuals with childbirth complications, and continued screening for depression and anxiety can identify individuals at risk for PPD. Such efforts can inform targeted interventions to improve maternal mental health, which plays a vital role in infant development.

Massive open online course adoption amongst newly graduated health care providers.

Massive Open Online Courses (MOOCs) are flexible offerings that deliver content to a large audience in a virtual platform. MOOCs are increasingly accessed by health professionals to support their own professional development. Despite the agreed usefulness of MOOCs, the rates of adoption are still extremely low. This study sought to understand the personal and social factors associated with MOOC adoption. Participants were newly graduated occupational therapists who registered for a leadership skills development MOOC. Qualitative interviews were conducted to understand unique perspectives of participants who did and did not complete the MOOC. Data were analyzed using the Unified Theory of Acceptance and Use of Technology (UTAUT) framework. Participants reported they found the MOOC content beneficial in providing a foundational framework on which to develop their leadership skills. Even though MOOC content was organized into multiple small components, participants shared that they would engage with the material once a week for up to two hours. Participants reported a high level of comfort accessing the technology to complete the MOOC, however they reported that they would have preferred more interactive or synchronous learning opportunities. MOOCs are an efficient way to offer a wide variety of educational offerings to health professionals. Despite their asynchronous nature, MOOC developers should consider maximizing opportunities for learner interaction and content application learning opportunities within MOOCs to increase their overall adoption.

Neurodevelopmental and Growth Outcomes of Extremely Preterm Infants with Short Bowel Syndrome.

OBJECTIVE: To determine if preterm infants with surgical necrotizing enterocolitis (sNEC) or spontaneous intestinal perforation (SIP) with short bowel syndrome (SBS) have worse neurodevelopmental and growth outcomes than those with sNEC/SIP without SBS, and those with no necrotizing enterocolitis, SIP, or SBS. STUDY DESIGN: We undertook a retrospective analysis of prospectively collected data from infants born between 22 and 26 weeks of gestation in the National Institute of Child Health and Human Development Neonatal Research Network centers from January 1, 2008, to December 31, 2016. Survivors were assessed at 18-26 months corrected age by standardized neurologic examination and Bayley Scales of Infant and Toddler Development, Third Edition. The primary outcome was moderate-severe neurodevelopmental impairment. Growth was assessed using World Health Organization z-score standards. Adjusted relative risks were estimated using modified Poisson regression models. RESULTS: Mortality was 32%, 45%, and 21% in the 3 groups, respectively. Eighty-nine percent of survivors were seen at 18-26 months corrected age. Moderate-severe neurodevelopmental impairment was present in 77% of children with SBS compared with 62% with sNEC/SIP without SBS (adjusted relative risk, 1.22; 95% CI, 1.02-1.45; P = .03) and 44% with no necrotizing enterocolitis, SIP, or SBS (adjusted relative risk, 1.60; 95% CI, 1.37-1.88; P < .001). Children with SBS had lowcognitive, language, and motor scores than children with sNEC/SIP without SBS. At follow-up, length and head circumference z-scores remained more than 1 SD below the mean for children with SBS. CONCLUSIONS: Preterm infants with sNEC/SIP and SBS had increased risk of adverse neurodevelopmental outcomes at 18-26 months corrected age and impaired growth compared with peers with sNEC/SIP without SBS or without any of these conditions.

Survival and Neurodevelopmental Outcomes among Periviable Infants.

BACKGROUND: Data reported during the past 5 years indicate that rates of survival have increased among infants born at the borderline of viability, but less is known about how increased rates of survival among these infants relate to early childhood neurodevelopmental outcomes. METHODS: We compared survival and neurodevelopmental outcomes among infants born at 22 to 24 weeks of gestation, as assessed at 18 to 22 months of corrected age, across three consecutive birth-year epochs (2000-2003 [epoch 1], 2004-2007 [epoch 2], and 2008-2011 [epoch 3]). The infants were born at 11 centers that participated in the National Institute of Child Health and Human Development Neonatal Research Network. The primary outcome measure was a three-level outcome - survival without neurodevelopmental impairment, survival with neurodevelopmental impairment, or death. After accounting for differences in infant characteristics, including birth center, we used multinomial generalized logit models to compare the relative risk of survival without neurodevelopmental impairment, survival with neurodevelopmental impairment, and death. RESULTS: Data on the primary outcome were available for 4274 of 4458 infants (96%) born at the 11 centers. The percentage of infants who survived increased from 30% (424 of 1391 infants) in epoch 1 to 36% (487 of 1348 infants) in epoch 3 (P<0.001). The percentage of infants who survived without neurodevelopmental impairment increased from 16% (217 of 1391) in epoch 1 to 20% (276 of 1348) in epoch 3 (P=0.001), whereas the percentage of infants who survived with neurodevelopmental impairment did not change significantly (15% [207 of 1391] in epoch 1 and 16% [211 of 1348] in epoch 3, P=0.29). After adjustment for changes in the baseline characteristics of the infants over time, both the rate of survival with neurodevelopmental impairment (as compared with death) and the rate of survival without neurodevelopmental impairment (as compared with death) increased over time (adjusted relative risks, 1.27 [95% confidence interval {CI}, 1.01 to 1.59] and 1.59 [95% CI, 1.28 to 1.99], respectively). CONCLUSIONS: The rate of survival without neurodevelopmental impairment increased between 2000 and 2011 in this large cohort of periviable infants.

Hand Function at 18-22 Months Is Associated with School-Age Manual Dexterity and Motor Performance in Children Born Extremely Preterm.

OBJECTIVES: To determine associations between hand function at age 18-22 months (early) and scores on the Movement Assessment Battery for Children, 2nd edition (MABC) at 6-7 years of age (school age) in extremely preterm children. STUDY DESIGN: Prospective multicenter cohort of 313 extremely preterm children with early hand function assessment and school-age MABC testing. Early hand function was compared with "definite deficits" (MABC <5th percentile) and MABC standard scores. Early hand function was categorized as "no deficit" vs "any deficit." Mixed-effects regression models were used to evaluate the association of early hand function with MABC deficits, controlling for multiple demographic, neonatal, and childhood factors. RESULTS: Children with early hand function deficits were more likely to have definite school-age deficits in all MABC subtests (Manual Dexterity, Aiming and Catching, and Balance) and to have received physical or occupational therapy (45% vs 26%; P < .001). Children with early hand function deficits had lower Manual Dexterity (P = .006), Balance (P = .035), and Total Test (P = .039) scores. Controlling for confounders, children with early hand function deficits had higher odds of definite school-age deficits in Manual Dexterity (aOR, 2.78; 95% CI, 1.36-5.68; P = .005) and lower Manual Dexterity (P = .031) and Balance (P = .027) scores. When excluding children with cerebral palsy and those with an IQ <70, hand function deficits remained significantly associated with manual dexterity. CONCLUSION: Hand function deficits at age 18-22 months are associated with manual dexterity deficits and motor difficulties at school age, independent of perinatal-neonatal factors and the use of occupational or physical therapy. This has significant implications for school success, intervention, and rehabilitative therapy development.

Behavior Profiles at 2 Years for Children Born Extremely Preterm with Bronchopulmonary Dysplasia.

OBJECTIVE: To characterize behavior of 2-year-old children based on the severity of bronchopulmonary dysplasia (BPD). STUDY DESIGN: We studied children born at 22-26 weeks of gestation and assessed at 22-26 months of corrected age with the Child Behavior Checklist (CBCL). BPD was classified by the level of respiratory support at 36 weeks of postmenstrual age. CBCL syndrome scales were the primary outcomes. The relationship between BPD grade and behavior was evaluated, adjusting for perinatal confounders. Mediation analysis was performed to evaluate whether cognitive, language, or motor skills mediated the effect of BPD grade on behavior. RESULTS: Of 2310 children, 1208 (52%) had no BPD, 806 (35%) had grade 1 BPD, 177 (8%) had grade 2 BPD, and 119 (5%) had grade 3 BPD. Withdrawn behavior (P < .001) and pervasive developmental problems (P < .001) increased with worsening BPD grade. Sleep problems (P = .008) and aggressive behavior (P = .023) decreased with worsening BPD grade. Children with grade 3 BPD scored 2 points worse for withdrawn behavior and pervasive developmental problems and 2 points better for externalizing problems, sleep problems, and aggressive behavior than children without BPD. Cognitive, language, and motor skills mediated the effect of BPD grade on the attention problems, emotionally reactive, somatic complaints, and withdrawn CBCL syndrome scales (P values < .05). CONCLUSIONS: BPD grade was associated with increased risk of withdrawn behavior and pervasive developmental problems but with decreased risk of sleep problems and aggressive behavior. The relationship between BPD and behavior is complex. Cognitive, language, and motor skills mediate the effects of BPD grade on some problem behaviors.

The Diagnosis of Bronchopulmonary Dysplasia in Very Preterm Infants. An Evidence-based Approach.

Rationale: Current diagnostic criteria for bronchopulmonary dysplasia rely heavily on the level and duration of oxygen therapy, do not reflect contemporary neonatal care, and do not adequately predict childhood morbidity.Objectives: To determine which of 18 prespecified, revised definitions of bronchopulmonary dysplasia that variably define disease severity according to the level of respiratory support and supplemental oxygen administered at 36 weeks' postmenstrual age best predicts death or serious respiratory morbidity through 18-26 months' corrected age.Methods: We assessed infants born at less than 32 weeks of gestation between 2011 and 2015 at 18 centers of the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network.Measurements and Main Results: Of 2,677 infants, 683 (26%) died or developed serious respiratory morbidity. The diagnostic criteria that best predicted this outcome defined bronchopulmonary dysplasia according to treatment with the following support at 36 weeks' postmenstrual age, regardless of prior or current oxygen therapy: no bronchopulmonary dysplasia, no support (n = 773); grade 1, nasal cannula ≤2 L/min (n = 1,038); grade 2, nasal cannula >2 L/min or noninvasive positive airway pressure (n = 617); and grade 3, invasive mechanical ventilation (n = 249). These criteria correctly predicted death or serious respiratory morbidity in 81% of study infants. Rates of this outcome increased stepwise from 10% among infants without bronchopulmonary dysplasia to 77% among those with grade 3 disease. A similar gradient (33-79%) was observed for death or neurodevelopmental impairment.Conclusions: The definition of bronchopulmonary dysplasia that best predicted early childhood morbidity categorized disease severity according to the mode of respiratory support administered at 36 weeks' postmenstrual age, regardless of supplemental oxygen use.

Behavioral Deficits at 18-22 Months of Age Are Associated with Early Cerebellar Injury and Cognitive and Language Performance in Children Born Extremely Preterm.

OBJECTIVE: To investigate associations in toddlers born extremely preterm (<28 weeks) between neonatal neuroimaging and 18- to 22-month developmental and behavioral outcomes. STUDY DESIGN: Cohort analysis from the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network Surfactant Positive Airway Pressure and Pulse Oximetry Trial Neuroimaging and Neurodevelopmental Outcomes Study of infants born extremely preterm. Subjects underwent cranial ultrasonography and near-term magnetic resonance imaging (MRI). At 18-22 months of corrected age, the assessment included the Brief Infant Toddler Social Emotional Assessment (BITSEA) Problem and Competence Scale scores and the Bayley Scales of Infant Development, Third Edition (Bayley-III). The BITSEA Problem Scale assesses dysregulation; the Competence Scale assesses social-emotional competence. We examined associations of Problem and Competence scores and positive screen rates with cranial ultrasonography and near-term MRI. Mean BITSEA and Bayley-III scores were compared using ANOVA and positive screen rates with the χ2 test. We computed correlations between BITSEA and Bayley-III scores. RESULTS: Of the 397 children, positive BITSEA screens were found in 34% for the Problem score and 26% for the Competence score. Presence of lesions on near-term MRI that included cerebellar lesions were significantly associated with lower BITSEA Competence but not with Problem scores; Competence scores were inversely related to the presence/significance of lesions. Positive screens on Competence scores and on both Competence and Problem scores were significantly associated with Bayley-III cognitive and language scores <85 (P < .001). CONCLUSIONS: Social-emotional competence contributes to deficits in cognitive and language development. Presence of injury on near-term MRI that includes cerebellar lesions is associated with later social-emotional competence and may be a useful predictor to guide early assessment and intervention.
