RESUMO
IMPACT: Parent-reported children's sleep duration is a primary outcome measure in population-level studies, and is the primary driver of pharmacotherapy such as melatonin. Accelerometry using the Fitbit suggests that few adolescents sleep for the optimal 9-12 h as recommended by the American Academy of Sleep Medicine, and most parent reports grossly overestimate average nightly sleep duration. Parent reports of adolescent sleep duration are unreliable, and quantitative assessment of children's sleep duration should be considered when a significant step such as pharmacotherapy is undertaken for sleep.
RESUMO
Objectives: To evaluate whether prenatal tobacco exposure (PTE) is related to poorer cognitive performance, abnormal brain morphometry, and whether poor cognitive performance is mediated by PTE-related structural brain differences. Methods: The Adolescent Brain Cognitive Development study dataset was used to compare structural MRI data and neurocognitive (NIH Toolbox®) scores in 9-to-10-year-old children with (n=620) and without PTE (n=10,989). We also evaluated whether PTE effects on brain morphometry mediated PTE effects on neurocognitive scores. Group effects were evaluated using Linear Mixed Models, covaried for socio-demographics and prenatal exposures to alcohol and/or marijuana, and corrected for multiple comparisons using the false-discovery rate (FDR). Results: Compared to unexposed children, those with PTE had poorer performance (all p-values <0.05) on executive function, working memory, episodic memory, reading decoding, crystallized intelligence, fluid intelligence and overall cognition. Exposed children also had thinner parahippocampal gyri, smaller surface areas in the posterior-cingulate and pericalcarine cortices; the lingual and inferior parietal gyri, and smaller thalamic volumes (all p-values <0.001). Furthermore, among children with PTE, girls had smaller surface areas in the superior-frontal (interaction-FDR-p=0.01), precuneus (interaction-FDR-p=0.03) and postcentral gyri (interaction-FDR-p=0.02), while boys had smaller putamen volumes (interaction-FDR-p=0.02). Smaller surface areas across regions of the frontal and parietal lobes, and lower thalamic volumes, partially mediated the associations between PTE and poorer neurocognitive scores (p-values <0.001). Conclusions: Our findings suggest PTE may lead to poorer cognitive performance and abnormal brain morphometry, with sex-specific effects in some brain regions, in pre-adolescent children. The poor cognition in children with PTE may result from the smaller areas and subcortical brain volumes.
RESUMO
Background: Continuous positive airway pressure (CPAP) is frequently prescribed for patients with residual obstructive sleep apnea (OSA) following adenotonsillectomy. Objectives: The goal was to examine the efficacy of noninvasive ventilation with average volume-assured pressure support (AVAPS) as a potential option for children with failed CPAP titration. Methods: In a single-center retrospective study, we included children aged 1-17 years, with polysomnographically confirmed OSA who underwent AVAPS titration following failed CPAP titration. In addition to describing the clinical characteristics of the included patients, we compared polysomnographic parameters before and after AVAPS. Results: Nine patients met the inclusion criteria; out of them, 8 (89%) were males with an age range of 6.7 ± 3.9 years and a body mass index percentile of 81.0 ± 28.9. Reasons for failed CPAP titration were: 3 (33%) patients due to inability to control apnea-hypopnea index (AHI), 3 (33%) patients due to sleep-related hypoventilation, 2 (22%) patients due to treatment-emergent central sleep apnea, and 1 (11%) patient due to intolerance to CPAP. AVAPS resulted in a greater reduction in AHI than CPAP (reduction following CPAP = 24.6 ± 29.3, reduction following AVAPS = 42.5 ± 37.6, p = 0.008). All patients had resolution of the problems which caused CPAP failure. Conclusion: In this case a series of children with OSA and with failed CPAP titration, AVAPS resulted in a greater reduction in AHI compared with CPAP as well as resolution of the problems which caused CPAP failure.
RESUMO
Diagnosis of obstructive sleep apnea (OSA) in children with sleep-disordered breathing (SDB) requires hospital-based, overnight level I polysomnography (PSG). Obtaining a level I PSG can be challenging for children and their caregivers due to the costs, barriers to access, and associated discomfort. Less burdensome methods that approximate pediatric PSG data are needed. The goal of this review is to evaluate and discuss alternatives for evaluating pediatric SDB. To date, wearable devices, single-channel recordings, and home-based PSG have not been validated as suitable replacements for PSG. However, they may play a role in risk stratification or as screening tools for pediatric OSA. Further studies are needed to determine if the combined use of these metrics could predict OSA.
RESUMO
OBJECTIVE: Untreated sleep-disordered breathing (SDB) is associated with problem behaviors in children. The neurological basis for this relationship is unknown. We used functional near-infrared spectroscopy (fNIRS) to assess the relationship between cerebral hemodynamics of the frontal lobe of the brain and problem behaviors in children with SDB. STUDY DESIGN: Cross-sectional. SETTING: Urban tertiary care academic children's hospital and affiliated sleep center. METHODS: We enrolled children with SDB aged 5 to 16 years old referred for polysomnography. We measured fNIRS-derived cerebral hemodynamics within the frontal lobe during polysomnography. We assessed parent-reported problem behaviors using the Behavioral Response Inventory of Executive Function Second Edition (BRIEF-2). We compared the relationships between (i) the instability in cerebral perfusion in the frontal lobe measured fNIRS, (ii) SDB severity using apnea-hypopnea index (AHI), and (iii) BRIEF-2 clinical scales using Pearson correlation (r). A p < .05 was considered significant. RESULTS: A total of 54 children were included. The average age was 7.8 (95% confidence interval, 7.0-8.7) years; 26 (48%) were boys and 25 (46%) were Black. The mean AHI was 9.9 (5.7-14.1). There is a statistically significant inverse relationship between the coefficient of variation of perfusion in the frontal lobe and BRIEF-2 clinical scales (range of r = 0.24-0.49, range of p = .076 to <.001). The correlations between AHI and BRIEF-2 scales were not statistically significant. CONCLUSION: These results provide preliminary evidence for fNIRS as a child-friendly biomarker for the assessment of adverse outcomes of SDB.

Bullying victimization is associated with a doubled risk of attempting suicide in adulthood. Two longitudinal brain morphometry studies identified the fusiform gyrus and putamen as vulnerable to bullying. No study identified how neural alterations may mediate the effect of bullying on cognition. We assessed participants with caregiver-reported bullying (N = 323) and matched non-bullied controls (N = 322) from the Adolescent Brain Cognitive Development Study dataset to identify changes in brain morphometry associated with ongoing bullying victimization over two years and determine whether such alterations mediated the effect of bullying on cognition. Bullied children (38.7% girls, 47.7% racial minorities, 9.88 ± 0.62 years at baseline) had poorer cognitive performance (P < 0.05), larger right hippocampus (P = 0.036), left entorhinal cortex, left superior parietal cortex, and right fusiform gyrus volumes (all P < 0.05), as well as larger surface areas in multiple other frontal, parietal, and occipital cortices. Thinner cortices were also found in the left hemisphere, particularly in the left temporal lobe, and right frontal region (all P < 0.05). Importantly, larger surface area in the fusiform cortices partially suppressed (12-16%), and thinner precentral cortices partially mitigated, (7%) the effect of bullying on cognition (P < 0.05). These findings highlight the negative impact of prolonged bullying victimization on brain morphometry and cognition.

OBJECTIVE: Cervical lymphadenopathy is a frequent finding in children that poses diagnostic challenges. We sought to compare the utility of fine needle aspiration (FNA) with ultrasound (US) for evaluating pediatric cervical lymphadenopathy based on published literature. STUDY DESIGN: In October 2019, we performed a comprehensive electronic search of PubMed, OVID (MEDLINE), EMBASE, and Scopus databases. Two authors independently screened and assessed full-text reports of potentially eligible studies. We compared sensitivity, specificity, positive predictive value estimates, and balanced accuracy for determining the underlying etiology of lymphadenopathy. RESULTS: The initial search returned 7736 possible studies, of which 31 met the criteria for inclusion. A total of 25 studies were included in the final analysis, with a total of 4721 patients, of which 52.8% were male. Of these, 9 (36.0%) examined US, and 16 (64%) examined fine needle aspiration. The pooled balanced accuracy for determining etiology was 87.7% for US and 92.9% for FNA. Reactive lymphadenopathy was identified in 47.9%, 9.2% were malignant, 12.6% were granulomatous, and 6.6% were non-diagnostic. CONCLUSIONS: In this systematic review, US was identified as an accurate initial diagnostic imaging modality in children. Fine needle aspiration was found to play a significant role in ruling out malignant lesions and potentially avoiding excisional biopsy.

OBJECTIVES: To describe the long-term outcomes related to breathing, feeding, and neurocognitive development in extremely premature infants requiring tracheostomy. STUDY DESIGN: Pooled cross-sectional survey. SETTING: Multi-institutional academic children's hospitals. METHODS: Extremely premature infants who underwent tracheostomy between January 1, 2012, and December 31, 2019, at four academic hospitals were identified from an existing database. Information was gathered from responses to a questionnaire by caregivers regarding airway status, feeding, and neurodevelopment 2-9 years after tracheostomy. RESULTS: Data was available for 89/91 children (96.8%). The mean gestational age was 25.5 weeks (95% CI 25.2-25.7) and mean birth weight was 0.71 kg (95% CI 0.67-0.75). Mean post gestational age at tracheostomy was 22.8 weeks (95% CI 19.0-26.6). At time of the survey, 18 (20.2%) were deceased. 29 (40.8%) maintained a tracheostomy, 18 (25.4%) were on ventilatory support, and 5 (7%) required 24-h supplemental oxygen. Forty-six (64.8%) maintained a gastrostomy tube, 25 (35.2%) had oral dysphagia, and 24 (33.8%) required a modified diet. 51 (71.8%) had developmental delay, 45 (63.4%) were enrolled in school of whom 33 (73.3%) required special education services. CONCLUSIONS: Tracheostomy in extremely premature neonates is associated with long term morbidity in the pulmonary, feeding, and neurocognitive domains. At time of the survey, about half are decannulated, with a majority weaned off ventilatory support indicating improvement in lung function with age. Feeding dysfunction is persistent, and a significant number will have some degree of neurocognitive dysfunction at school age. This information may help caregivers regarding expectations and plans for resource management.

BACKGROUND: The aim of this study was to determine the extent to which socioeconomic characteristics of the home and neighborhood are associated with racial inequalities in brain outcomes. METHODS: We performed a cross-sectional analysis of the baseline dataset (v.2.0.1) from the Adolescent Brain and Cognitive Development (ABCD) Study. Cognitive performance was assessed using the National Institutes of Health Toolbox (NIH-TB) cognitive battery. Standard socioeconomic indicators of the family and neighborhood were derived from census-related statistics. Cortical morphometric measures included MRI-derived thickness, area, and volume. RESULTS: 9638 children were included. Each NIH-TB cognitive measure was negatively associated with household and neighborhood socioeconomic characteristics. Differences in cognitive scores between Black or Hispanic children and other racial groups were mitigated by higher household income. Most children from lowest-income families or residents in impoverished neighborhoods were Black or Hispanic. These disparities were associated with racial differences in NIH-TB measures and mediated by smaller cortical brain volumes. CONCLUSIONS: Neighborhood socioeconomic characteristics are associated with racial differences in preadolescent brain outcomes and mitigated by greater household income. Household income mediates racial differences more strongly than neighborhood-level socioeconomic indicators in brain outcomes. Highlighting these socioeconomic risks may direct focused policy-based interventions such as allocation of community resources to ensure equitable brain outcomes in children. IMPACT: Neighborhood socioeconomic characteristics are associated with racial differences in preadolescent brain outcomes and mitigated by greater household income. Household income mediates racial differences more strongly than neighborhood-level socioeconomic indicators in brain outcomes. Highlighting these disparities related to socioeconomic risks may direct focused policy-based interventions such as allocation of community resources to ensure equitable brain outcomes in children.

BACKGROUND: The aim of this study was to compare the impact of a semi-upright swing with a standard crib on vital signs in infants in the neonatal intensive care unit (NICU). METHODS: We performed a within-subjects' comparison of vital signs of NICU infants corrected to ≥34 weeks of gestation and placed in the supine position versus the semi-upright position in a swing. The primary outcome was the mean oxygen saturation, and the secondary outcomes were the mean heart rate, the proportion of time with oxygen saturation (SpO2) <90%, and respiratory rate. RESULTS: Of the 65 infants, 34 (57%) were male and 32 (50%) were black. The mean ± SD gestational age at birth was 32.4 ± 5.1 weeks. In all, 40% were on noninvasive respiratory support. There were no significant differences in oxygen saturation, heart rate, time with oxygen desaturation defined by SpO2 < 90%, or respiratory rate between the supine and semi-upright positions. A higher risk of desaturations was observed in infants without respiratory support (RR, 1.24, 95% CI, 1.15-1.33) and low-birth-weight infants (RR, 1.55, 95% CI, 1.42-1.69). CONCLUSIONS: The placement of infants in a semi-upright swing resulted in no discernible differences in averaged vital signs compared to the supine position in NICU infants. IMPACT: We identified no significant differences in averaged oxygen saturation, heart rate, or respiratory rate among NICU infants placed in a semi-upright swing compared to the supine position. Desaturation events occurred at a higher frequency in low-birth-weight infants and those on room air when placed in the swing, although none required oxygen supplementation. The results from the current study support that it is probably safe to use semi-upright swings in the NICU environment, although additional studies are necessary for generalization to the unmonitored home environment.

Objective: Peer victimization is a substantial early life stressor linked to psychiatric symptoms and poor academic performance. However, the sex-specific cognitive or behavioral outcomes of bullying have not been well-described in preadolescent children. Methods: Using the baseline dataset of the Adolescent Brain Cognitive Development (ABCD) Study 2.0.1 data repository (N = 11,875), we evaluated associations between parent-reported bullying victimization, suicidality (suicidal ideation, intent, and/or behavior), and non-suicidal self-injury (NSSI), as well as internalizing and externalizing behavioral problems, cognition, and academic performance. Results: Of the 11,015 9-10-year-old children included in the analyses (5,263 girls), 15.3% experienced bullying victimization, as reported by the primary caregiver. Of these, boys were more likely to be bullied than girls (odds ratio [OR], 1.2 [95% CI, 1.1-1.3]; p = 0.004). Children who were bullied were more likely to display NSSI or passive suicidality (OR, 2.4 [95% CI, 2.0-2.9]; p < 0.001) and active suicidality (OR, 3.4 [95% CI, 2.7-4.2]; p < 0.001). Bullied children also had lower cognitive scores, greater behavioral problems, and poorer grades (p < 0.001). Across all participants, boys had poorer grades and greater behavioral problems than girls; however, bullied boys had greater behavioral problems than girls in several areas (p < 0.001). Compared to their non-bullied peers, bullied children with greater non-suicidal self-injury or suicidality also had greater behavioral problems and poorer grades (p < 0.001). Conclusion: These findings highlight the sex-specific effects of bullying, and the negative associations of bullying victimization with cognitive performance, behavioral problems, and academic performance. Future longitudinal studies will identify the natural history and neural correlates of these deficits during adolescence.
RESUMO
Importance: Adenotonsillectomy, performed for approximately 500â¯000 children annually in the US alone, is the first line of treatment of pediatric obstructive sleep apnea (OSA). The Childhood Adenotonsillectomy Trial (CHAT), the first randomized clinical trial to test the efficacy of adenotonsillectomy, compared the management of pediatric nonsevere OSA by early adenotonsillectomy (eAT) vs watchful waiting with supportive care. Since the publication of the primary article in 2013, the CHAT study data set were made available via the National Sleep Research Resource, which allowed researchers to address a range of additional clinical questions relevant to the care of children with OSA. This review focuses on secondary analyses associated with the CHAT data set as grouped by the outcome of interest. Observations: The results of most secondary analyses suggest that children who underwent eAT experienced the greatest improvements in symptom burden, sleepiness, parent-reported behavior, and quality of life. Changes in other domains, such as cognition, cardiovascular physiology, and metabolic indicators, were modest and selective. The associations between most treatment outcomes and polysomnographic parameters were weak. Symptoms were poor predictors of OSA severity. The results from these secondary analyses benefitted from the rigor of multicenter design and centralized polysomnography interpretation in CHAT. However, the exclusion of younger preschool-aged children and children with primary snoring limited the generalizability of findings. In addition, because caregivers were not masked, some of the parent-reported outcomes may have been inflated. Conclusions and Relevance: The results of this narrative review suggest that CHAT provides a model for future OSA-related studies in children for design, conduct, and subsequent reuse of the study data set, and its findings have advanced our understanding of the pathophysiology and management of pediatric nonsevere OSA. Directions for future research include whether the findings from this landmark study are generalizable to younger children and children with primary snoring and severe OSA. Similar studies may help address practice variability associated with pediatric OSA and help identify children who are most likely to benefit from undergoing eAT.

INTRODUCTION: Pediatric obstructive sleep apnea (OSA) is diagnosed and stratified by polysomnography. However, due to cost and inaccessibility, up to 90% of children undergo tonsillectomy and adenoidectomy (T&A) solely based on clinical criteria. We previously developed a data-driven brief screening questionnaire ('Selected Features,' SF) that predicted OSA severity than alternatives. The SF asks the parent whether a child: (i) has had breath-holding spells at night over the past 4 weeks, (ii) is a mouth-breather during the day, (iii) has stopped growing at a normal rate any time since birth, and (iv) is overweight. This study sought prospectively validate the SF questionnaire. METHODS: We conducted a prospective assessment of the predictive accuracy of SF compared to the Pediatric Sleep Questionnaire-Sleep Related Breathing Disorder (PSQ-SRBD) scale in otherwise healthy children with sleep disordered breathing referred for T&A. We compared the model fits of PSQ-SRDB and SF for (i) a linear regression model for the prediction of OSA, and (ii) a logistic regression model for severe OSA, defined as apnea hypopnea index (AHI) > 10. P < 0.05 was significant. RESULTS: A total of 124 patients were included. The average age was 7.3 years (95% confidence interval, 6.6-8.0) and 66 (54%) were male. The racial composition was 54 (44%) black, 41 (33%) white, and 28 (23%) other. The median AHI was 4.8 (interquartile range 12) and 43 (35%) of patients had severe OSA. In linear and logistic regression models, SF outperformed the PSQ-SRBD and null models as measured by Akaike Information Criteria. The overall accuracy in predicting AHI >10 for PSQ-SRBD was 0.65 (0.56-0.73, P = 0.54) compared to 0.73 (0.64-0.80, P = 0.04) for SF. CONCLUSION: By eliminating redundancy, we have developed a questionnaire with improved prediction of OSA and its severity, in children with high pre-test probability of the condition. While multi-site validation is necessary, SF demonstrates value in screening children prior to T&A in resource-limited environments.

OBJECTIVES: Children with obstructive sleep apnea (OSA) who undergo adenotonsillectomy (AT) often experience post-operative weight gain, although the mechanism remains unclear. Our aim is to understand how changes in sleep events impact changes in weight in children with OSA following adenotonsillectomy compared to watchful waiting with supportive care. METHODS: We performed a secondary analysis of the Childhood adenotonsillectomy trial (CHAT) dataset in which children with OSA were randomized to undergo early adenotonsillectomy (eAT) or watchful waiting with supportive care (WWSC). The primary outcome measures included changes in body mass index (BMI) percentile, apnea-hypopnea index (AHI) and arousal index (AI) during rapid eye movement (REM) sleep. The change in BMI percentile attributable to changes in AHI and AI during REM sleep was determined using causal mediation analysis. RESULTS: Of the 453 children with OSA randomized to eAT or WWSC, 397 children were included in the analysis. Children in the eAT arm experienced a greater increase in their weight as measured by BMI percentile, compared to children who received WWSC (WWSC 4.12 (2.70, 5.55) vs. eAT 6.62 (4.87, 8.38), Cohen's d = 0.22 (0.02, 0.42), p = 0.02). A significant proportion of the weight gain was attributable to decreases in apneic events (proportion mediated 19% (2-97%), p = 0.03) and arousals (proportion mediated 20% (5-78%), p = 0.01) during REM sleep. CONCLUSION: A significant proportion of post-adenotonsillectomy weight gain in children with OSA is attributable to polysomnographic changes during REM sleep, potentially due to the mitigation of REM-related sleep fragmentation and subsequent reduction in metabolic expenditure.

In this study, we present the case of a 10-year-old boy with a left-sided neck mass. Although most neck masses in children are non-cancerous, their etiology can be complex, especially in neck masses of congenital origin. The workup of a pediatric neck mass includes imaging and cytopathology. In this case, the histopathology of the excised mass revealed thymic tissue, which helped establish the diagnosis of a thymopharyngeal duct cyst. Thymophayngeal duct cysts, although rare, can be diagnosed preoperatively by characteristic tapering toward the mediastinum. Cytopathology may demonstrate Hassall corpuscles. These unique features can help disentangle the differential diagnoses, which commonly include thyroglossal duct cysts, venolymphatic malformations, and branchial cleft cysts.
RESUMO
OBJECTIVES/HYPOTHESIS: Obstructive sleep apnea (OSA) is associated with higher risk of morbidity and mortality related to cardiovascular disease (CVD). Due to overlapping clinical risk factors, identifying high-risk patients with OSA who are likely to develop CVD remains challenging. We aimed to identify baseline clinical factors associated with the future development of CVD in patients with OSA. STUDY DESIGN: Retrospective analysis of prospectively collected data. METHODS: We performed a retrospective analysis of 967 adults aged 45 to 84 years and enrolled in the Multi-Ethnic Study of Atherosclerosis. Six machine learning models were created using baseline clinical factors initially identified by stepwise variable selection. The performance of these models for the prediction of additional risk of CVD in OSA was calculated. Additionally, these models were evaluated for interpretability using locally interpretable model-agnostic explanations. RESULTS: Of the 967 adults without baseline OSA or CVD, 116 were diagnosed with OSA and CVD and 851 with OSA alone 10 years after enrollment. The best performing models included random forest (sensitivity 84%, specificity 99%, balanced accuracy 91%) and bootstrap aggregation (sensitivity 84%, specificity 100%, balanced accuracy 92%). The strongest predictors of OSA and CVD versus OSA alone were fasting glucose >91 mg/dL, diastolic pressure >73 mm Hg, and age >59 years. CONCLUSION: In the selected study population of adults without OSA or CVD at baseline, the strongest predictors of CVD in patients with OSA include fasting glucose, diastolic pressure, and age. These results may shape a strategy for cardiovascular risk stratification in patients with OSA and early intervention to mitigate CVD-related morbidity. LEVEL OF EVIDENCE: 3 Laryngoscope, 132:234-241, 2022.

OBJECTIVES: Adenotonsillectomy (AT) is the first line of treatment for pediatric obstructive sleep apnea (OSA). In some treatment guidelines, children with moderate to severe OSA, defined as apnea-hypopnea index (AHI) ≥ 5, may be recommended AT regardless of symptoms. The differences in outcomes between children randomized to watchful waiting with supportive care (WWSC) or AT were compared based on baseline OSA severity threshold of AHI≥ 5. METHODS: A secondary analysis of the Childhood Adenotonsillectomy Trial, a randomized controlled trial of children with OSA aged 5-9 years who underwent AT or WWSC, was performed. The primary outcome was the change in neurocognition measured by Developmental Neuropsychological Assessment (NEPSY). Secondary outcomes included changes in behavior, symptoms of OSA, and quality of life. Outcomes were measured at baseline and the seven-month follow-up after grouping children based on whether their AHI was greater than or equal to 5. Comparisons were performed using two-way analysis of covariance (ANCOVA) while controlling for age, sex and race. Differences in treatment effect were measured using Cohen's d. RESULTS: Of the 397 children included, 203 received WWSC and 194 underwent AT. The treatment effects on post-randomization changes in neurocognition, measured by NEPSY in children with AHI ≥5 (Cohen's d = 0.1 [95% CI, -0.1 to 0.4]) was not significantly different from children with AHI <5 (Cohen's d = 0.1 [95% CI, -0.1 to 0.4]). Furthermore, among children in the AT group alone, the effects of AT on post-treatment changes in NEPSY did not differ based on AHI threshold (Cohen's d = -0.06 [95% CI, -0.3 to 0.2]). Additionally, the treatment effects on post-randomization changes in behavior, symptoms, and quality of life did not vary based on AHI threshold. CONCLUSION: The outcomes of neurocognition, behavior, symptoms, and quality of life did not differ between children with OSA randomized to WWSC or AT based on OSA severity threshold alone. Additionally, the effects of AT on post-treatment outcomes did not differ based on AHI threshold.

Obstructive sleep apnea (OSA) is a known risk factor for cardiovascular disease in adults. It is associated with incident systemic hypertension, arrhythmia, stroke, coronary artery disease, and heart failure. OSA is common in children and adolescents, but there has been less focus on OSA as a primary risk factor for cardiovascular disease in children and adolescents. This scientific statement summarizes what is known regarding the impact of sleep-disordered breathing and, in particular, OSA on the cardiovascular health of children and adolescents. This statement highlights what is known regarding the impact of OSA on the risk for hypertension, arrhythmia, abnormal ventricular morphology, impaired ventricular contractility, and elevated right heart pressure among children and adolescents. This scientific statement also summarizes current best practices for the diagnosis and evaluation of cardiovascular disease-related complications of OSA in children and adolescents with sleep apnea and highlights potential future research in the area of sleep-disordered breathing and cardiovascular health during childhood and adolescence.

OBJECTIVES: Advances in neonatal intensive care have allowed successful resuscitation of children born at the border of viability. However, there has been little change in the incidence of bronchopulmonary dysplasia (BPD) and anatomical upper airway obstruction which may require a tracheostomy in that group. The benefits of the procedure are accompanied by sequelae that impact outcomes. Information about these issues can assist caregivers in making decisions and planning care after discharge from the neonatal intensive care unit (NICU). The objectives of this study were to describe the clinical characteristics of neonates born in the periviable period (≤25 weeks gestation) requiring tracheotomy and to highlight their hospital course, complications and status upon NICU discharge. METHODS: Retrospective analysis at four tertiary care academic children's hospitals. Medical records of neonates born ≤25 weeks gestation who required tracheotomy between January 1, 2012 and December 31, 2018 were reviewed. Demographics, medical comorbidities, and tracheostomy related complications were studied. Feeding, ventilation, and neurodevelopmental outcomes at time of transfer from NICU were evaluated. RESULTS: Fifty-two patients were included. The mean gestational age was 24.3 (95% confidence interval, 24.1 to 24.5) weeks. The mean birth weight was 635 (95% CI: 603 to 667) grams and 50 (96.2%) children had BPD. At time of discharge from the NICU, 47 (90.4%) required mechanical ventilation, four (7.7%) required supplemental oxygen and one (1.9%) was weaned to room air. Forty-two (80.8%) were discharged with a gastrostomy tube, seven (28%) with a nasogastric tube, and three (5.8%) were on oral feeds. Two (3.8%) suffered hypoxic ischemic encephalopathy, 27 (51.9%) had neurodevelopmental delay, seven (13.5%) were diagnosed with another anomaly, and 16 (30.8%) were considered normal. Complications related to the procedure were observed in 28 (53.8%) neonates. Granulation tissue was seen in 17 (32.7%), wound break down or cellulitis in three (5.8%), one (1.9%) with tracheostomy plugging, three (5.8%) with dislodgement of the tracheostomy tube and four (7.7%) developed tracheitis. CONCLUSIONS: Tracheostomy in infants born in the periviable period is primarily performed for BPD and portends extended ventilatory dependence. It is associated with non-oral alimentation at the time of discharge from the NICU and developmental delay. Mortality directly related to the procedure is rare. Minor complications are common but do not require surgical intervention. These data may aid in counseling caregivers about the procedure in this vulnerable population.

Parents frequently report behavioral problems among children who snore. Our understanding of the relationship between symptoms of obstructive sleep disordered breathing (oSDB) and childhood behavioral problems associated with brain structural alterations is limited. Here, we examine the associations between oSDB symptoms, behavioral measures such as inattention, and brain morphometry in the Adolescent Brain Cognitive Development (ABCD) study comprising 10,140 preadolescents. We observe that parent-reported symptoms of oSDB are associated with composite and domain-specific problem behaviors measured by parent responses to the Child Behavior Checklist. Alterations of brain structure demonstrating the strongest negative associations with oSDB symptoms are within the frontal lobe. The relationships between oSDB symptoms and behavioral measures are mediated by significantly smaller volumes of multiple frontal lobe regions. These results provide population-level evidence for an association between regional structural alterations in cortical gray matter and problem behaviors reported in children with oSDB.
