Children with heart conditions, particularly CHDs, may experience adverse neurodevelopmental and psychosocial outcomes. Our study aimed to: (1) compare national prevalence of mental, behavioural, and developmental disorders among children by heart condition status and (2) identify associated characteristics among children with heart conditions.

Nationally representative data from the National Survey of Children’s Health (2016–2021) on U.S. children aged 6–17 years without Down syndrome were analysed. Caregivers reported whether a healthcare provider told them their child has ever had a heart condition or currently has depression, anxiety, ADHD, behavioural, or conduct problems, Tourette syndrome, autism spectrum disorder, developmental delay, intellectual disability, learning disability, or a speech or other language disorder. Logistic regression analysis compared disorder prevalence by heart condition status and, among children with heart conditions, assessed whether disorders were associated with demographic and contextual characteristics.

Among 3,440 children with heart conditions, 42% had an examined disorder, compared to 23% of 133,280 children without heart conditions (adjusted prevalence ratio = 1.8; 95% confidence interval: 1.7, 2.0). Each disorder was more prevalent among children with versus without heart conditions (adjusted prevalence ratio range: 1.9 to 5.1), with anxiety (22.1%), ADHD (20.4%), and learning disabilities (19.6%) most common. Among children with heart conditions, disorders were consistently associated with an increased number of adverse childhood experiences.

These findings support clinical guidelines recommending neurodevelopmental and mental health screening and interventions for children with heart conditions and can be used as a national baseline to gauge progress of guideline implementation.

“Frailty” is associated with worse outcomes in adult cardiology. There is limited data on the associations between frailty and outcomes in paediatric cardiology. We aimed to define the prevalence of frailty and identify associations between frailty and neurodevelopmental and quality-of-life outcomes in high-risk paediatric cardiac populations.

This cross-sectional study included patients 4–18 years seen in a neurodevelopmental programme between 6/2017 and 11/2022. Demographic and clinical data were obtained from medical records. As part of the routine care, physical therapy assessment and neurocognitive, psychosocial, adaptive functioning, and quality-of-life surveys were administered. Social determinants of health were assessed by insurance status and Childhood Opportunity Index. Frailty was defined as the abnormality in 3 of 5 categories: body composition, weakness, slowness, physical activity, and exhaustion. Chi-Square, Student t, and Wilcoxon Rank Sum tests were used to assess differences between frail and non-frail groups.

Of the 270 patients, 101 (37%) met the frailty criteria. Frailty was not associated with social determinants of health, cardiac diagnosis, genetic syndrome, number of cardiac surgeries, or history of clinical complications. Frail patients were more likely to be older (p = 0.004) and have neurocognitive (p = 0.024), emotional (p = 0.003), social (p < 0.001), motor (p < 0.001), and adaptive dysfunction (p < 0.001) and lower quality of life (p = 0.029).

Frailty is common in school-aged patients with cardiac disease and is associated with adverse neurocognitive, psychosocial, motor, and adaptive outcomes and worse quality of life. Risk stratification for frailty may be a critical evaluation and screening element of high-risk cardiac patients in neurodevelopmental programmes.

Children with CHD are at increased risk for neurodevelopmental disabilities and neuropsychological impairments throughout their life span. The purpose of this report is to share our experience building a sustainable, novel, inpatient, interdisciplinary Neurocardiac Critical Care Program to mitigate risks and optimize outcomes during the ICU stay.

A descriptive review was chosen to identify meaningful characteristics, challenges and lessons learned related to the establishment, expansion of and sustainability of Neurocardiac Critical Care Program in a 26-bed pediatric cardiac ICU.

We successfully launched, expanded, and sustained an interdisciplinary Neurocardiac Critical Care Program. Here, we share the foundation, framework, challenges, and lessons learned as we established and sustained the Neurocardiac Critical Care Program. The key elements of our program are (1) consistent engagement by pediatric neurologists in the cardiac ICU, (2) comprehensive education initiatives, (3) evidence-based clinical practice changes, and (4) quality improvement and research projects.

The development of a pediatric Neurocardiac Critical Care Program is feasible and sustainable. This program was informed by recent research related to perioperative and psychosocial risk factors that impact brain development and neurodevelopmental outcomes in this vulnerable population. By aligning our efforts, our multidisciplinary team is helping shift the paradigm in pediatric cardiac critical care to actively manage complex heart disease, while simultaneously and proactively mitigating risks to the developing brain and family unit.

Mentalizing—our ability to make inferences about the mental states of others—is impaired across psychiatric disorders and robustly associated with functional outcomes. Mentalizing deficits have been prominently linked to aberrant activity in cortical regions considered to be part of the “social brain network” (e.g., dorsomedial prefrontal cortex, temporoparietal junction), yet emerging evidence also suggests the importance of cerebellar dysfunction. In the present study—using a transdiagnostic, clinical psychiatric sample spanning the psychosis-autism-social anxiety spectrums—we examined the role of the cerebellum in mentalizing and its unique contributions to broader social functioning.

Sixty-two participants (38 with significant social dysfunction secondary to psychiatric illness and 24 nonclinical controls without social dysfunction) completed a mentalizing task during functional magnetic resonance imaging. General linear model analysis, latent variable modeling, and regression analyses were used to examine the contribution of cerebellum activation to the prediction of group status and social functioning.

Mentalizing activated a broad set of social cognitive brain regions, including cerebral mentalizing network (MN) nodes and posterior cerebellum. Higher posterior cerebellum activation significantly predicted clinical status (i.e., individuals with psychiatric disorders versus nonclinical controls). Finally, cerebellar activation accounted for significant variance in social functioning independent of all other cerebral MN brain regions identified in a whole-brain analysis.

Findings add to an accumulating body of evidence establishing the unique role of the posterior cerebellum in mentalizing deficits and social dysfunction across psychiatric illnesses. Collectively, our results suggest that the posterior cerebellum should be considered – alongside established cerebral regions – as part of the mentalizing network.

The prenatal and early-life periods pose a crucial neurodevelopmental window whereby disruptions to the intestinal microbiota and the developing brain may have adverse impacts. As antibiotics affect the human intestinal microbiome, it follows that early-life antibiotic exposure may be associated with later-life psychiatric or neurocognitive outcomes.

To explore the association between early-life (in utero and early childhood (age 0–2 years)) antibiotic exposure and the subsequent risk of psychiatric and neurocognitive outcomes.

A search was conducted using Medline, PsychINFO and Excerpta Medica databases on 20 November 2023. Risk of bias was assessed using the Newcastle-Ottawa scale, and certainty was assessed using the grading of recommendations, assessment, development and evaluation (GRADE) certainty assessment.

Thirty studies were included (n = 7 047 853 participants). Associations were observed between in utero antibiotic exposure and later development of autism spectrum disorder (ASD) (odds ratio 1.09, 95% CI: 1.02–1.16) and attention-deficit hyperactivity disorder (ADHD) (odds ratio 1.19, 95% CI: 1.11–1.27) and early-childhood exposure and later development of ASD (odds ratio 1.19, 95% CI: 1.01–1.40), ADHD (odds ratio 1.33, 95% CI: 1.20–1.48) and major depressive disorder (MDD) (odds ratio 1.29, 95% CI: 1.04–1.60). However, studies that used sibling control groups showed no significant association between early-life exposure and ASD or ADHD. No studies in MDD used sibling controls. Using the GRADE certainty assessment, all meta-analyses but one were rated very low certainty, largely owing to methodological and statistical heterogeneity.

While there was weak evidence for associations between antibiotic use in early-life and later neurodevelopmental outcomes, these were attenuated in sibling-controlled subgroup analyses. Thus, associations may be explained by genetic and familial confounding, and studies failing to utilise sibling-control groups must be interpreted with caution. PROSPERO ID: CRD42022304128

Several organizations including the Environmental Protection Agency, World Health Organization and American Academy of Pediatrics recommend that hospital sound levels not exceed 45 decibels. Yet, several studies across multiple age groups have observed higher than recommended levels in the intensive care setting. Elevated sound levels in hospitals have been associated with disturbances in sleep, patient discomfort, delayed recovery, and delirium.

We measured sound levels in a pediatric cardiac intensive care unit and collected vital signs data, sedation dosing and delirium scores. During a 5-week study period, sound levels for 68 patients in 22 private and 4 semi-private rooms were monitored.

Sound levels were consistently above stated recommendations with an average daytime level of 50.6 decibels (maximum, 76.9 decibels) and an average nighttime level of 49.5 decibels (maximum, 69.6 decibels). An increase in average and maximum sound levels increased the probability of sedation administration the following hour (p-value < 0.001 and 0.01, respectively) and was predictive of an increase in heart rate and blood pressure (p-value < 0.001).

Sound levels in the CICU were consistently higher than recommended. An increase in heart rate, blood pressure and sedation utilization may suggest a stress response to persistent and sudden loud sounds. Given known negative impacts of excessive noise on stress, sleep, and brain development, as well as the similar adverse effects from the related use of sedative medications, reducing excessive and sudden noise may provide an opportunity to improve short- and long-term hemodynamic and neurodevelopmental outcomes in the pediatric cardiac intensive care unit.

Associations between childhood trauma, neurodevelopment, alcohol use disorder (AUD), and posttraumatic stress disorder (PTSD) are understudied during adolescence.

Using 1652 participants (51.75% female, baseline Mage = 14.3) from the Collaborative Study of the Genetics of Alcoholism, we employed latent growth curve models to (1) examine associations of childhood physical, sexual, and non-assaultive trauma (CPAT, CSAT, and CNAT) with repeated measures of alpha band EEG coherence (EEGc), and (2) assess whether EEGc trajectories were associated with AUD and PTSD symptoms. Sex-specific models accommodated sex differences in trauma exposure, AUD prevalence, and neural development.

In females, CSAT was associated with higher mean levels of EEGc in left frontocentral (LFC, ß = 0.13, p = 0.01) and interhemispheric prefrontal (PFI, ß = 0.16, p < 0.01) regions, but diminished growth in LFC (ß = −0.07, p = 0.02) and PFI (ß = −0.07, p = 0.02). In males, CPAT was associated with lower mean levels (ß = −0.17, p = 0.01) and increased growth (ß = 0.11, p = 0.01) of LFC EEGc. Slope of LFC EEGc was inversely associated with AUD symptoms in females (ß = −1.81, p = 0.01). Intercept of right frontocentral and PFI EEGc were associated with AUD symptoms in males, but in opposite directions. Significant associations between EEGc and PTSD symptoms were also observed in trauma-exposed individuals.

Childhood assaultive trauma is associated with changes in frontal alpha EEGc and subsequent AUD and PTSD symptoms, though patterns differ by sex and trauma type. EEGc findings may inform emerging treatments for PTSD and AUD.

To evaluate the motor proficiency, identify risk factors for abnormal motor scores, and examine the relationship between motor proficiency and health-related quality of life in school-aged patients with CHD.

Patients ≥ 4 years old referred to the cardiac neurodevelopmental program between June 2017 and April 2020 were included. Motor skills were evaluated by therapist-administered Bruininks-Oseretsky Test of Motor Proficiency Second-Edition Short Form and parent-reported Adaptive Behavior Assessment System and Patient-Reported Outcomes Measurement Inventory System Physical Functioning questionnaires. Neuropsychological status and health-related quality of life were assessed using a battery of validated questionnaires. Demographic, clinical, and educational variables were collected from electronic medical records. General linear modelling was used for multivariable analysis.

The median motor proficiency score was the 10th percentile, and the cohort (n = 272; mean age: 9.1 years) scored well below normative values on all administered neuropsychological questionnaires. In the final multivariable model, worse motor proficiency score was associated with family income, presence of a genetic syndrome, developmental delay recognised in infancy, abnormal neuroimaging, history of heart transplant, and executive dysfunction, and presence of an individualised education plan (p < 0.03 for all predictors). Worse motor proficiency correlated with reduced health-related quality of life. Parent-reported adaptive behaviour (p < 0.001) and physical functioning (p < 0.001) had a strong association with motor proficiency scores.

This study highlights the need for continued motor screening for school-aged patients with CHD. Clinical factors, neuropsychological screening results, and health-related quality of life were associated with worse motor proficiency.

CHD predisposes children to neurodevelopmental delays. Frequent, prolonged hospitalisations during infancy prevent children with heart disease from participating in recommended language and cognitive development programmes, such as outpatient early childhood literacy programmes, and contribute to caregiver stress, a risk factor for adverse developmental outcomes. This study aims to describe the implementation of a single-centre inpatient early childhood literacy programme for hospitalised infants with heart disease and assess its impact on reading practices and patient–family hospital experience.

Admitted infants ≤1 year old receive books, a calendar to track reading frequency, and reading guidance at regular intervals. Voluntary feedback is solicited from caregivers using an anonymous, QR-code survey on books. A prospective survey also assessed programme impact on hospital experience.

From February 2021 to November 2023, the Books@Heart programme provided 1,293 books to families of 840 infants, of whom 110 voluntarily submitted feedback. Caregivers reported a significant improvement in access to books (p < 0.001) and increased reading frequency after learning about Books@Heart (p = 0.003), with the proportion reading to their child daily increasing from 27% to 62%. Among 40 prospective survey responses, caregivers reported feeling a sense of personal fulfillment (60%), self-confidence (30%), connection (98%), and personal well-being (40%) while reading to their child.

An inpatient early childhood literacy programme is a well-received intervention for infants with heart disease that promotes development, improves book access, increases reading exposure, and engages families. Further studies are needed to assess its impact on sustained reading practices and neurodevelopmental outcomes.
