Abstract
BACKGROUND Viral bronchiolitis is a common cause of acute respiratory failure requiring intubation for infants. Bacterial respiratory tract infections can occur with bronchiolitis, although their prevalence and impact on outcomes are unclear, especially with increased use of noninvasive respiratory support. METHODS This was a single-center retrospective cohort study of children <2 years old requiring intubation in the emergency department for bronchiolitis from 2012 to 2017 who had viral testing plus a lower respiratory culture obtained. We evaluated the impact of bacterial codetection (positive respiratory culture plus moderate or many polymorphonuclear neutrophils on Gram stain) on mechanical ventilation (MV) duration and intensive care unit length of stay using multivariable gamma regression. RESULTS Of 149 patients enrolled, 52% had bacterial codetection. In adjusted analysis, patients with codetection had shorter MV duration [adjusted relative risk (aRR) 0.819, 95% confidence interval (CI): 0.69-0.98; marginal mean duration of 5.31 days (4.71-5.99) compared to 6.48 days (5.72-7.35) without codetection]. Patients with codetection had a shorter intensive care unit stay [aRR 0.806 (0.69-0.94); marginal mean length of stay 6.9 days (6.21-7.68) vs. 8.57 days (7.68-9.56) without codetection]. The association between codetection and duration of ventilation appears confined to those receiving earlier antibiotics (less than the median time) rather than later antibiotics [aRR 0.738 (0.56-0.95) for earlier vs. aRR 0.92 (0.70-1.18) for later]. CONCLUSIONS Respiratory bacterial codetection is common and associated with shorter MV duration in infants requiring early intubation for bronchiolitis. Early antibiotics may contribute to these outcomes, but further multicenter studies are needed to understand the role of codetection and antibiotics on bronchiolitis outcomes.

Faculty Decision Making in Ad Hoc Entrustment of Pediatric Critical Care Fellows: A National Case-Based Survey. TEACHING AND LEARNING IN MEDICINE 2023:1-8. [PMID: 37933862 DOI: 10.1080/10401334.2023.2269402] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/15/2023] [Accepted: 10/02/2023] [Indexed: 11/08/2023]
Abstract
Phenomenon: Ad hoc entrustment decisions reflect a clinical supervisor's estimation of the amount of supervision a trainee needs to successfully complete a task in the moment. These decisions have important consequences for patient safety, trainee learning, and preparation for independent practice. Determinants of these decisions have previously been described but have not been well described for acute care contexts such as critical care and emergency medicine. The ad hoc entrustment of trainees caring for vulnerable patient populations is a high-stakes decision that may differ from other contexts. Critically ill patients and children are vulnerable patient populations, making the ad hoc entrustment of a pediatric critical care medicine (PCCM) fellow a particularly high-stakes decision. This study sought to characterize how ad hoc entrustment decisions are made for PCCM fellows through faculty ratings of vignettes. The authors investigated how acuity, relationship, training level, and task interact to influence ad hoc entrustment decisions. Approach: A survey containing 16 vignettes that varied by four traits (acuity, relationship, training level, and task) was distributed to U.S. faculty of pediatric critical care fellowships in 2020. Respondents determined an entrustment level for each case and provided demographic data. Entrustment ratings were dichotomized by "high entrustment" versus "low entrustment" (direct supervision or observation only). The authors used logistic regression to evaluate the individual and interactive effects of the four traits on dichotomized entrustment ratings. Findings: One hundred seventy-eight respondents from 30 institutions completed the survey (44% institutional response rate). Acuity, relationship, and task all significantly influenced the entrustment level selected but did not interact. Faculty most frequently selected "direct supervision" as the entrustment level for vignettes, including for 24% of vignettes describing fellows in their final year of training. Faculty rated the majority of vignettes (61%) as "low entrustment." There was no relationship between faculty or institutional demographics and the entrustment level selected. Insights: As has been found in summative entrustment for pediatrics, internal medicine, and surgery trainees, PCCM fellows often rated at or below the "direct supervision" level of ad hoc entrustment. This may relate to declining opportunities to practice procedures, a culture of low trust propensity among the specialty, and/or variation in interpretation of entrustment scales.

A genome-wide association analysis of loss of ambulation in dystrophinopathy patients suggests multiple candidate modifiers of disease severity. Eur J Hum Genet 2023; 31:663-673. [PMID: 36935420 PMCID: PMC10250491 DOI: 10.1038/s41431-023-01329-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2021] [Revised: 01/27/2023] [Accepted: 02/21/2023] [Indexed: 03/21/2023] Open
Abstract
The major determinant of disease severity in Duchenne muscular dystrophy (DMD) or milder Becker muscular dystrophy (BMD) is whether the dystrophin gene (DMD) mutation truncates the mRNA reading frame or allows expression of a partially functional protein. However, even in the complete absence of dystrophin, variability in disease severity is observed, and candidate gene studies have implicated several genes as modifiers. Here we present the largest genome-wide search to date for loci influencing severity in N = 419 DMD patients. Availability of subjects for such studies is quite limited, leading to modest sample sizes, which present a challenge for GWAS design. We have therefore taken special steps to minimize heterogeneity within our dataset at the DMD locus itself, taking a novel approach to mutation classification to effectively exclude the possibility of residual dystrophin expression, and utilized statistical methods that are well adapted to smaller sample sizes, including the use of a novel linear regression-like residual for time to ambulatory loss and the application of evidential statistics for the GWAS approach. Finally, we applied an unbiased in silico pipeline, utilizing functional genomic datasets to explore the potential impact of the best supported SNPs. In all, we obtained eight SNPs (out of 1,385,356 total) with posterior probability of trait-marker association (PPLD) ≥ 0.4, representing six distinct loci. Our analysis prioritized likely non-coding SNP regulatory effects on six genes (ETAA1, PARD6G, GALNTL6, MAN1A1, ADAMTS19, and NCALD), each with plausibility as a DMD modifier. These results support both recurrent and potentially new pathways for intervention in the dystrophinopathies.

Abstract
Although survey reports are common, fewer than 10% of medical journals provide clear guidelines to investigators for survey research. In this special article, we provide guidance on minimum recommendations in the form of a CHecklist for Allergy and Immunology Reporting of Survey research (CHAIRS). Key components to consider include providing background information, such as a clear statement of the research hypothesis and question, and rationale for the study. When considering sample selection, a clear understanding of the relationship between the target population, sampling frame, sample scheme, representativeness, and sample size is needed. Review of the survey tool by content experts and assessment of threats to survey validity should occur early in questionnaire development with consideration of cognitive interviews and pretesting to facilitate accurate measurement. Last, a transparent description of data collection and qualitative and quantitative characteristics of response rate is needed to ensure that appropriate inferences and conclusions can be drawn from the survey research.

Type III Interferons, Viral Loads, Age, and Disease Severity in Young Children With Respiratory Syncytial Virus Infection. J Infect Dis 2022; 227:61-70. [PMID: 36200173 DOI: 10.1093/infdis/jiac404] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Revised: 09/27/2022] [Accepted: 10/03/2022] [Indexed: 01/19/2023] Open
Abstract
BACKGROUND The interplay among respiratory syncytial virus (RSV) loads, mucosal interferons (IFN), and disease severity in RSV-infected children is poorly understood. METHODS Children <2 years of age with mild (outpatients) or severe (inpatients) RSV infection and healthy controls were enrolled, and nasopharyngeal samples obtained for RSV loads and innate cytokines quantification. Patients were stratified by age (0-6 and >6-24 months) and multivariable analyses performed to identify predictors of disease severity. RESULTS In 2015-2019 we enrolled 219 RSV-infected children (78 outpatients; 141 inpatients) and 34 healthy controls. Type I, II, and III IFN concentrations were higher in children aged >6 versus 0-6 months and, like CXCL10, they were higher in outpatients than inpatients and correlated with RSV loads (P < .05). Higher IL6 concentrations increased the odds of hospitalization (odds ratio [OR], 2.30; 95% confidence interval [CI], 1.07-5.36) only in children >6 months, while higher IFN-λ2/3 concentrations had the opposite effect irrespective of age (OR, 0.38; 95% CI, .15-.86). Likewise, higher CXCL10 concentrations decreased the odds of hospitalization (OR, 0.21; 95% CI, .08-.48), oxygen administration (OR, 0.42; 95% CI, .21-.80),PICU admission (OR, 0.39; 95% CI, .20-.73), and prolonged hospitalization (OR, 0.57; 95% CI, .32-.98) irrespective of age. CONCLUSIONS Children with milder RSV infection and those aged >6 months had higher concentrations of mucosal IFNs, suggesting that maturation of mucosal IFN responses are associated with protection against severe RSV disease.

Abstract
BACKGROUND Current recommendations for early detection tools for cerebral palsy (CP) include assessments that vary in feasibility and resource requirements. The predictive value of less resource-intensive tools has not been fully explored. AIMS To determine the predictive value of the Test of Infant Motor Performance (TIMP) at 3-4 months corrected age (CA) for CP, and whether administration of both the TIMP and the Hammersmith Infant Neurological Exam (HINE) improves early CP detection. STUDY DESIGN Five-year retrospective observational study of infants who received the TIMP and the HINE at 3-4 months CA in a high-risk follow-up clinic. TIMP and HINE cut-off scores (alone and in combination) were compared for CP discriminatory ability. SUBJECTS Of patients with HINE scores (n = 1389; 676 [48.7 %] female; median gestational age at birth 31 weeks [interquartile range 29-34 weeks]), 1343 had concurrent TIMP scores available. OUTCOME MEASURES Clinical diagnosis of CP. RESULTS HINE total score <57 had optimal CP predictive value (AUC = 0.815; 77 % sensitivity; 91 % specificity) compared to optimal TIMP cut-off (1 SD below the mean, AUC = 0.71; 52 % sensitivity; 94 % specificity) and all tested TIMP and HINE combinations (all p < 0.001). CONCLUSIONS HINE total score <57 at 3-4 months CA had the best CP predictive value, confirming its value absent first-line detection tools. Concurrent administration of TIMP did not improve predictive value.

Abstract
OBJECTIVE To describe real-world baseline characteristics and patient-reported outcomes (PROs) at 6- and 12-month follow-up visits among patients with psoriasis who initiated and maintained secukinumab, stratified by prior exposure to biologics. METHODS This real-world study included patients enrolled in the CorEvitas (formerly Corrona) Psoriasis Registry who initiated and maintained secukinumab through 6- and/or 12-month follow-up. Demographics, clinical characteristics, and PROs were collected. PROs included Dermatology Life Quality Index (DLQI); itch, skin pain, fatigue, and EuroQol visual analog scales; and Work Productivity and Activity Impairment. Mean (SD) differences between baseline and follow-up visits were calculated for all outcomes. RESULTS Overall, 652 patients had a 6-month follow-up visit, 460 (70.6%) were biologic experienced and 192 (29.4%) were biologic naive. Biologic-experienced and biologic-naive patients reported mean (SD) improvements in all PROs measured at 6-month follow-up. Similar improvements were seen among patients with a 12-month follow-up visit (n = 390) and both 6- and 12-month follow-up visits (n = 326). CONCLUSIONS Biologic-experienced and biologic-naive patients with psoriasis who initiated and maintained secukinumab treatment reported improvements in PROs at 6- and/or 12-month follow-up visits. These findings suggest that secukinumab is a potential biologic for psoriasis at any point along the patient treatment journey.

Abstract
OBJECTIVE To define parenting/social characteristics associated with better-than-expected cognitive and motor outcomes in preschoolers at similar perinatal biological risk-level including various gestational ages at birth (GA) and perinatal complications. STUDY DESIGN Prospective cohort study (n = 87) of children at four years, median GA 29 weeks (IQR 26, 38). Assessments included Differential Ability Scales, Movement Assessment Battery, parenting styles, and social risk scores. Perinatal risk factors were weighted based on regression models for each outcome; individual calculated risk scores became predictors to extract standardized residuals from the mean (>1 SD above mean = better-than-expected). Mixed-effect regressions examined associations between positive adaptation and parenting/social factors. RESULT Perinatal risk scores explained 21-53% outcome variability. Children across all GA displayed positive adaptation. Children of parents with higher authoritarian scores had higher odds of better-than-expected outcomes (OR 1.17, p = 0.0002). CONCLUSION Parental structure may promote positive adaptation at preschool age in children with perinatal risk factors for poor development, including extreme prematurity.

Abstract
INTRODUCTION Healthcare providers' anthropometric characteristics can adversely affect adult cardiopulmonary resuscitation (CPR) performance quality. However, their effects on infant CPR are unknown. We aimed to determine any relationships between healthcare provider characteristics (anthropomorphic, demographics, training, occupational data) and simulated infant CPR performance at multiple international sites. Our secondary aim was to examine provider's CPR performance degradation. METHODS Providers from 4 international hospitals performed 2 minutes of single-rescuer simulated infant CPR using 2015 American Heart Association Basic Life Support criteria with guidance from a real-time visual performance feedback device. Providers' characteristics were collected, and the simulator collected compression and ventilation data. Multivariate analyses examined the entire 2 minutes and performance degradation. RESULTS Data from 127 participants were analyzed. Although median values for all compression variables (depth, rate, lean) and ventilation volume were within guideline target ranges, when looking at individuals, only 52% chest compressions and 20% ventilations adhered to the American Heart Association guidelines. Age was found to be independently associated with ventilation volume (direct-relationship), and height was associated with chest compression lean (shorter participant-deeper lean). No significant differences were noted based on sex or body mass index. Neonatal intensive care unit participants were noted to perform shallower chest compressions (P < 0.001). Overall, there was minimal evidence of performance degradation over 2 minutes. CONCLUSIONS Isolated provider characteristics were noted among a diverse cohort of healthcare providers that may affect the CPR quality on a simulated infant. Understanding the relationships between provider characteristics and CPR quality could inform future infant CPR guidelines customized for the provider and not just the patient.

Abstract
BACKGROUND AND OBJECTIVES To describe the phenotypic spectrum of dystrophinopathy in a large cohort of individuals with DMD exon 2 duplications (Dup2), who may be particularly amenable to therapies directed at restoring expression of either full-length dystrophin or nearly full-length dystrophin through utilization of the DMD exon 5 internal ribosome entry site (IRES). METHODS In this retrospective observational study, we analyzed data from large genotype-phenotype databases (the United Dystrophinopathy Project [UDP] and the Italian DMD network) and classified participants into Duchenne muscular dystrophy (DMD), intermediate muscular dystrophy (IMD), or Becker muscular dystrophy (BMD) phenotypes. Log-rank tests for time-to-event variables were used to compare age at loss of ambulation (LOA) in participants with Dup2 vs controls without Dup2 in the UDP database and for comparisons between steroid-treated vs steroid-naive participants with Dup2. RESULTS Among 66 participants with Dup2 (UDP = 40, Italy = 26), 61% were classified as DMD, 9% as IMD, and 30% as BMD. Median age at last observation was 15.4 years (interquartile range 8.79-26.0) and 75% had been on corticosteroids for at least 6 months. Age at LOA differed significantly between participants with Dup2 DMD and historical controls without Dup2 DMD (p < 0.001). Valid spirometry was limited but suggested a delay in the typical age-related decline in forced vital capacity and 24 of 55 participants with adequate cardiac data had cardiomyopathy. DISCUSSION Some patients with Dup2 display a milder disease course than controls without Dup2 DMD, and prolonged ambulation with corticosteroids suggests the potential of IRES activation as a molecular mechanism. As Dup2-targeted therapies reach clinical applications, this information is critical to aid in the interpretation of the efficacy of new treatments.

Myeloid-Derived Suppressor Cells and Clinical Outcomes in Children With COVID-19. Front Pediatr 2022; 10:893045.

Abstract
BACKGROUND Although children with COVID-19 account for fewer hospitalizations than adults, many develop severe disease requiring intensive care treatment. Critical illness due to COVID-19 has been associated with lymphopenia and functional immune suppression. Myeloid-derived suppressor cells (MDSCs) potently suppress T cells and are significantly increased in adults with severe COVID-19. The role of MDSCs in the immune response of children with COVID-19 is unknown. AIMS We hypothesized that children with severe COVID-19 will have expansion of MDSC populations compared to those with milder disease, and that higher proportions of MDSCs will correlate with clinical outcomes. METHODS We conducted a prospective, observational study on a convenience sample of children hospitalized with PCR-confirmed COVID-19 and pre-pandemic, uninfected healthy controls (HC). Blood samples were obtained within 48 h of admission and analyzed for MDSCs, T cells, and natural killer (NK) cells by flow cytometry. Demographic information and clinical outcomes were obtained from the electronic medical record and a dedicated survey built for this study. RESULTS Fifty children admitted to the hospital were enrolled; 28 diagnosed with symptomatic COVID-19 (10 requiring ICU admission) and 22 detected by universal screening (6 requiring ICU admission). We found that children with severe COVID-19 had a significantly higher percentage of MDSCs than those admitted to the ward and uninfected healthy controls. Increased percentages of MDSCs in peripheral blood mononuclear cells (PBMC) were associated with CD4+ T cell lymphopenia. MDSC expansion was associated with longer hospitalizations and need for respiratory support in children admitted with acute COVID-19. CONCLUSION These findings suggest that MDSCs are part of the dysregulated immune responses observed in children with severe COVID-19 and may play a role in disease pathogenesis. Future mechanistic studies are required to further understand the function of MDSCs in the setting of SARS-CoV-2 infection in children.

Abstract
OBJECTIVE This study describes the creation of a combination antibiogram directed toward Pseudomonas aeruginosa to determine the most appropriate empiric antimicrobial regimen(s). METHODS P aeruginosa isolates were collected from all sites between January 2013 and December 2017 for patients admitted to the PICU. Patients with cystic fibrosis and isolates from the same site and susceptibility pattern obtained within 30 days were excluded. β-Lactam susceptibilities were determined and compared with the addition of an aminoglycoside or fluroquinolone and summarized in a combination antibiogram. RESULTS One hundred ninety-nine P aeruginosa isolates were included for analysis. The addition of a second agent to piperacillin-tazobactam was shown to have the most significant improvement among the β-lactams, with 70% susceptibility as monotherapy and increases to above 90% with the addition of an aminoglycoside or fluroquinolone. The addition of an aminoglycoside or fluroquinolone to cefepime and meropenem increased coverage to above 95%. The addition of a second agent was likely to increase susceptibility of a monotherapy backbone; however, as the susceptibility of the first-line agent decreased, the susceptibility of the second agent needed to be higher to achieve a 95% coverage threshold. CONCLUSIONS Our results support use of a second agent to significantly improve the likelihood of appropriate empiric coverage of P aeruginosa. Use of a combination antibiogram may be more beneficial than a simple antibiogram for units with increasing resistance rates, or for coverage of specific resistant organisms.

Abstract
OBJECTIVE Children born preterm are at increased risk for autism spectrum disorder (ASD). However, early diagnosis of ASD is challenging because conventional screening Level 1 tools are less reliable in this population. We sought to determine whether the Autism Detection in Early Childhood (ADEC) and Child Behavior Checklist (CBCL) could accurately identify children at risk for ASD in a NICU Follow-up setting and thus facilitate referral for formal ASD evaluation. METHOD Children aged 18-36 months were recruited from a NICU Follow-up program. All children received presumptive diagnoses based on DSM-5 criteria and were screened for ASD risk with the ADEC and CBCL. Children scoring in the "at risk" range on either tool were referred for a full diagnostic ASD evaluation. RESULTS Sixty-nine patients (median birth weight 1140 g; median gestational age 28 weeks) were included with 18 designated "at risk" for ASD. Nine (13 %) scored "at risk" on the ADEC and 12 (17 %) on the CBCL. Thirteen children underwent diagnostic ASD evaluation with 9 receiving a formal diagnosis of ASD. The ADEC demonstrated the best performance (sensitivity 89 %, specificity 98 %). The CBCL was less sensitive (sensitivity 50 %, specificity 90 %). Requiring elevated scores on both the CBCL and ADEC was specific but not sensitive (sensitivity 33 %, specificity 100 %). CONCLUSION The ADEC performed well in identifying children at risk for ASD within this high-risk NICU cohort, adding benefit as an autism-specific screening tool over the CBCL alone.

Abstract
PURPOSE To determine whether asymmetry scores derived from the Hammersmith Infant Neurological Examination (HINE) can provide cutoff scores for recommending in-depth assessment of upper extremity functional deficits by therapists using the Hand Assessment for Infants (HAI). METHODS Observational study in a clinical laboratory with the HINE and the HAI administered concurrently to 101 infants 3 to 12 months corrected age developing typically or atypically. Predictive value of HINE asymmetry scores for atypical HAI was determined. RESULTS Total HINE asymmetry scores of 4 or greater had 100% sensitivity and 88% or greater specificity for identifying infants with an asymmetric HAI score of 3 or greater point difference between hands. CONCLUSIONS For infants receiving a total HINE asymmetry score of 4 or greater, referral to therapists for HAI assessment may be beneficial to precisely evaluate function and determine the need for targeted upper extremity interventions.

Abstract
OBJECTIVES To evaluate a guideline for antibiotic decisions in children with suspected ventilator-associated infection. DESIGN Prospective, observational cohort study conducted in 22 PICUs in the United States and Canada. SETTING PICUs in 22 hospitals from April 2017 to January 2019. SUBJECTS Children less than 3 years old on mechanical ventilation greater than 48 hours who had respiratory secretions cultured and antibiotics initiated for suspected ventilator-associated infection. INTERVENTIONS After baseline data collection in children with suspected ventilator-associated infection (Phase 1), a consensus guideline was developed for advising antibiotic continuation or stopping at 48-72 hours (Phase 2) and implemented (Phase 3). Guideline-based antibiotic recommendations were provided to the treating clinicians once clinical and microbiologic data were available. Demographic and outcome data were collected, and guideline compliance and antibiotic utilization evaluated for Phase 1 and Phase 3. MEASUREMENTS AND MAIN RESULTS Despite education and implementation efforts, guideline-concordant antibiotic management occurred in 158 of 227 (70%) Phase 3 subjects compared with 213 of 281 (76%) in Phase 1. Illness severity and positive respiratory cultures were the primary determinants of antibiotic continuation. For subjects with a positive respiratory culture but a score for which antibiotic discontinuation was recommended (score ≤ 2), only 27% of Phase 3 subjects had antibiotics discontinued. Antibiotic continuation was not associated with improved outcomes in these subjects and was associated with significantly longer duration of ventilation (median 5.5 d longer) and PICU stay (5 d longer) in the overall study population. Positive respiratory cultures were not associated with outcomes irrespective of antibiotic treatment. CONCLUSIONS Antibiotic guideline efficacy and safety remain uncertain due to clinician failure to follow the guideline, instead primarily relying on respiratory culture results. Strategies to overcome clinician perceptions of respiratory cultures and other barriers will be vital for improving guideline adherence and antibiotic use in suspected ventilator-associated infection in future studies.

Abstract
BACKGROUND The role of nasopharyngeal bacteria on RSV disease has been underestimated. We measured the frequency and quantitative detection of potentially pathogenic bacteria in the upper respiratory tract of infants with RSV infection over seven respiratory seasons, and their impact on clinical outcomes. METHODS Children <2 years old with mild (outpatients; n=115) or severe (inpatients; n=566) RSV infection, and matched healthy controls (n=161) were prospectively enrolled. Nasopharyngeal samples were obtained for RSV, S. pneumoniae, S. aureus, M. catarrhalis, and H. influenzae detection and quantitation by PCR. Multivariable models were constructed to identify variables predictive of severe disease. RESULTS S. pneumoniae, H. influenzae, and M. catarrhalis, but not S. aureus, were detected more frequently in RSV-infected children (84%) than healthy controls (46%; p<0.001). Detection of S. pneumoniae and/or H. influenzae was associated with fever, more frequent antibiotic treatment, worse radiologic findings, and higher neutrophil counts (p<0.01). In adjusted analyses S. pneumoniae/H. influenzae co-detection was associated with greater odds (OR; 95% CI) of hospitalization (2.25 [1.07-4.74), higher disease severity scores (1.93 [1.14-3.26]), prolonged oxygen administration (2.23 [1.01-4.91]), and longer hospitalization (2.53 [1.33-4.79]). CONCLUSIONS Nasopharyngeal co-detection of S. pneumoniae and H. influenzae in infants with RSV infection is associated with increased disease severity.

Abstract
Importance Ulceration is a common complication of infantile hemangioma (IH), which leads to substantial morbidity. Ulceration in IH has not been systematically studied since the advent of β-blocker therapy for IH. Objectives To examine treatment interventions used for ulceration in IH and identify clinical prognostic indicators of healing time. Design, Setting, and Participants A retrospective, multicenter cohort study was conducted on 436 consecutive patients with a clinical diagnosis of ulcerated IH and available clinical photographs. Patients receiving care at tertiary referral centers evaluated between 2012 and 2016 were included; statistical and data analysis were performed from February 7 to April 27, 2020. Exposures Clinical characteristics, treatment interventions, course, complications, and resource use were analyzed. Treatment interventions for ulceration in IH included local (wound care, topical), systemic (β-blocker, corticosteroids), and procedural (pulsed-dye laser). Main Outcomes and Measures The primary end point was time to complete or nearly complete ulceration healing. Clinical characteristics were analyzed to determine the responses to most common interventions and prognostic factors for healing of ulceration. Results Of the 436 patients included in the study, 327 were girls (75.0%); median age at ulceration was 13.7 weeks (interquartile range, 8.86-21.30 weeks). The median heal time was 4.79 weeks (95% CI, 3.71-5.86 weeks) with wound care alone, 5.14 weeks (95% CI, 4.57-6.00 weeks) with timolol, 6.36 weeks (95% CI, 5.57-8.00 weeks) with a systemic β-blocker, and 7.71 weeks (95% CI, 6.71-10.14 weeks) with multimodal therapy. After adjusting for IH size, a dose of propranolol less than or equal to 1 mg/kg/d was associated with shorter healing time compared with higher propranolol doses (hazard ratio, 2.04; 95% CI, 1.11 to 3.73; P = .02). Size of the IH was identified as a significant prognostic factor for healing time in multivariable analysis. Increasing size of IH portends a proportionately longer time to heal of the ulceration. Conclusions and Relevance Despite the use of β-blockers, this cohort study found that a subset of patients with IH ulceration continued to experience prolonged IH healing times. Larger IH size appears to be a poor prognostic factor for time to heal. For patients requiring systemic therapy, initiation of propranolol at lower doses (≤1 mg/kg/d) should be considered.

Immune profiles provide insights into respiratory syncytial virus disease severity in young children. Sci Transl Med 2021; 12:12/540/eaaw0268. [PMID: 32321862 DOI: 10.1126/scitranslmed.aaw0268] [Citation(s) in RCA: 39] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2018] [Revised: 11/21/2019] [Accepted: 03/05/2020] [Indexed: 12/29/2022]
Abstract
Respiratory syncytial virus (RSV) is associated with major morbidity in infants, although most cases result in mild disease. The pathogenesis of the disease is incompletely understood, especially the determining factors of disease severity. A better characterization of these factors may help with development of RSV vaccines and antivirals. Hence, identification of a "safe and protective" immunoprofile induced by natural RSV infection could be used as a as a surrogate of ideal vaccine-elicited responses in future clinical trials. In this study, we integrated blood transcriptional and cell immune profiling, RSV loads, and clinical data to identify factors associated with a mild disease phenotype in a cohort of 190 children <2 years of age. Children with mild disease (outpatients) showed higher RSV loads, greater induction of interferon (IFN) and plasma cell genes, and decreased expression of inflammation and neutrophil genes versus children with severe disease (inpatients). Additionally, only infants with severe disease had increased numbers of HLA-DRlow monocytes, not present in outpatients. Multivariable analyses confirmed that IFN overexpression was associated with decreased odds of hospitalization, whereas increased numbers of HLA-DRlow monocytes were associated with increased risk of hospitalization. These findings suggest that robust innate immune responses are associated with mild RSV infection in infants.

Impaired T lymphocyte responses during childhood Staphylococcus aureus infection. J Infect Dis 2021; 225:177-185. [PMID: 34145461 DOI: 10.1093/infdis/jiab326] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2021] [Accepted: 06/16/2021] [Indexed: 12/20/2022] Open
Abstract
BACKGROUND Staphylococcus aureus infections are common throughout the lifespan, with recurrent infections occuring in nearly half of infected children. There is no licensed vaccine, underscoring the need to better understand how S. aureus evades protective immunity. Despite much study, the relative contributions of antibodies and T cells to protection against S. aureus infections in humans are not fully understood. METHODS We prospectively quantified S. aureus-specific antibody levels by ELISA and T cell responses by ELISpot in S. aureus-infected and healthy children. RESULTS S. aureus-specific antibody levels and T cell responses increased with age in healthy children, suggesting a coordinated development of anti-staphylococcal immunity. Antibody levels against leukotoxin E (LukE) and Panton-Valentine leukocidin (LukS-PV), but not α-hemolysin (Hla), were higher in younger infected children, compared with healthy children; these differences disappeared in older children. We observed a striking impairment of global and S. aureus-specific T cell function in children with invasive and non-invasive infection, suggesting that S. aureus-specific immune responses are dysregulated during childhood infection regardless of the infection phenotype. CONCLUSIONS These findings identify a potential mechanism by which S. aureus infection actively evades adaptive immune responses, thereby preventing the development of protective immunty and maintaining susceptibility to recurrent infection.

Longitudinal MRI brain volume changes over one year in children with mucopolysaccharidosis types IIIA and IIIB. Mol Genet Metab 2021; 133:193-200.

Abstract
OBJECTIVE To quantify changes in segmented brain volumes over 12 months in children with mucopolysaccharidosis types IIIA and IIIB (MPS IIIA and IIIB). METHODS In order to establish suitable outcome measures for clinical trials, twenty-five children greater than 2 years of age were enrolled in a prospective natural history study of MPS IIIA and IIIB at Nationwide Children's Hospital. Data from sedated non-contrast brain 3 T MRIs and neuropsychological measures were reviewed from the baseline visit and at 12-month follow-up. No intervention beyond standard clinical care was provided. Age- and sex-matched controls were gathered from the National Institute of Mental Health Data Archive. Automated brain volume segmentation with longitudinal processing was performed using FreeSurfer. RESULTS Of the 25 subjects enrolled with MPS III, 17 children (4 females, 13 males) completed at least one MRI with interpretable volumetric data. The ages ranged from 2.8 to 13.7 years old (average 7.2 years old) at enrollment, including 8 with MPS IIIA and 9 with MPS IIIB. At baseline, individuals with MPS III demonstrated reduced cerebral white matter and corpus callosum volumes, but greater volumes of the lateral ventricles, cerebellar cortex, and cerebellar white matter compared to controls. Among the 13 individuals with MPS III with two interpretable MRIs, there were annualized losses or plateaus in supratentorial brain tissue volumes (cerebral cortex -42.10 ± 18.52 cm3/year [mean ± SD], cerebral white matter -4.37 ± 11.82 cm3/year, subcortical gray matter -6.54 ± 3.63 cm3/year, corpus callosum -0.18 ± 0.62 cm3/yr) and in cerebellar cortex (-0.49 ± 12.57 cm3/year), with a compensatory increase in lateral ventricular volume (7.17 ± 6.79 cm3/year). Reductions in the cerebral cortex and subcortical gray matter were more striking in individuals younger than 8 years of age. Greater cerebral cortex volume was associated with higher fine and gross motor functioning on the Mullen Scales of Early Learning, while greater subcortical gray matter volume was associated with higher nonverbal functioning on the Leiter International Performance Scale. Larger cerebellar cortex was associated with higher receptive language performance on the Mullen, but greater cerebellar white matter correlated with worse adaptive functioning on the Vineland Adaptive Behavioral Scales and visual problem-solving on the Mullen. CONCLUSIONS Loss or plateauing of supratentorial brain tissue volumes may serve as longitudinal biomarkers of MPS III age-related disease progression compared to age-related growth in typically developing controls. Abnormally increased cerebellar white matter in MPS III, and its association with worse performance on neuropsychological measures, suggest the possibility of pathophysiological mechanisms distinct from neurodegeneration-associated atrophy that warrant further investigation.

Abstract
OBJECTIVE To develop an improved interictal electroencephalogram (EEG) grading scale for children with infantile spasms founded on elements with adequate inter-rater reliability (IRR) to justify its further study for clinical and research purposes. METHODS Three blinded reviewers assessed five-minute sleep epochs in 93 EEGs from 62 children (31 consecutive controls, 31 consecutive infantile spasms [pretreatment and posttreatment studies]) using a longitudinal bipolar montage. We determined the IRR of background amplitude, epileptiform discharges, >3 spike foci (including <50 % or >50 %), grouped multifocal spikes, paroxysmal voltage attenuations, and symmetry of sleep spindles. Data were used to finalize the 2021 BASED (Burden of AmplitudeS and Epileptiform Discharges) score. RESULTS All elements included in the 2021 BASED score had moderate to near perfect IRR. Among controls, >200 μv background waves occurred commonly in the bilateral posterior temporal (T3-T5, T4-T6) and midline (Fz-Cz, Cz-Pz) regions. Excluding midline and occipital channels (which have normal high amplitude background waves), we designated abnormal high amplitude background waves as >200 μv for most channels, but >300 μv for T3-T5 and T4-T6. The IRR was moderate to near perfect for <50 % >3 spike foci, >50 % >3 spike foci, paroxysmal voltage attenuations, grouped multifocal spikes (GMFS), and symmetric sleep spindles. Paroxysmal voltage attenuations, GMFS, and >50 % >3 spike foci all significantly distinguished pretreatment from posttreatment studies whereas symmetric sleep spindles did not (as planned, the latter was not included in the 2021 BASED score). When the 2021 BASED score was applied to the 22 children with infantile spasms achieving clinical remission with treatment, 19 met criteria for electroclinical remission and three did not. SIGNIFICANCE The 2021 BASED score includes elements with high levels of IRR and correlates well with the presence or absence of infantile spasms.

Abstract
Mentorship is recognized as a critical approach to support successful careers in academic medicine. Obstacles to successful mentoring relationships include difficulty finding appropriate mentors and poor alignment of mentee/mentor interests and goals. We set out to investigate if concordance or discordance in personality traits of mentees and mentors impacts perceived success of mentoring relationships. Our findings indicated that concordance and discordance on one personality trait, neuroticism, seemed to significantly impact the perceived mentoring relationship success related to career progression. Further work to refine criteria for matching mentees and mentors considering personality traits may impact the effectiveness of mentoring relationships.

Abstract
This study examined if listening to music will improve the accuracy of blood pressure (BP) readings in children with Williams syndrome (WS). Fifty-two participants (7-12 years) were randomly assigned to a music or non-music group. BPs were obtained at two time points. There was a significant decrease in both systolic and diastolic BP from Time 1 to Time 2 for everyone. Participants from the music group had lower systolic BP readings at Time 2 than participants in the non-music group (Cohen's d = 0.33). Systolic BP readings were approximately 3.8 mmHg lower in the music group. Music may be beneficial in obtaining more accurate systolic BP readings in children with WS.

Abstract
AIM To examine associations between the deep medullary vein white matter injury global severity scoring system and neurodevelopmental impairment. METHODS This is a prospective observational cohort study of infants born at ≥32 weeks, diagnosed with deep medullary vein thrombosis and infarction on neuroimaging in the first month of life. Developmental testing was performed using validated measures for early, preschool, and school-age follow-up. RESULTS Nineteen (37%) patients had major neurodevelopmental impairment. Global severity score was higher among patients with neurodevelopmental impairment (21.6 vs 13.4, P = .04). Overall, 78% of patients with epilepsy had neurodevelopmental impairment. A greater degree of asymmetry with right-sided injury predominance was associated with lower Bayley-III cognitive scores and presence of neurodevelopmental impairment (P < .01). CONCLUSIONS Results suggest a need for targeted clinical surveillance for patients with a high global severity score and/or asymmetric, predominantly right cerebral white matter injury and for those who develop epilepsy.

Abstract
PURPOSE Intracranial pressure (ICP) > 20 mmHg is associated with worse outcomes in children. The gold standard for monitoring ICP is invasive, has complications such as bleeding and infection, and may not be available in resource limited areas. Ultrasound of the optic nerve sheath diameter (ONSD) has been studied as a noninvasive way to evaluate for elevated ICP in adults. Its utility in pediatrics remains unclear. METHODS A prospective study was performed in a pediatric intensive care unit in children ≤ 18 years old. ONSD ultrasound was performed using a 13-6 MHz linear probe with the patient's invasively measured ICP simultaneously recorded. Linear mixed effects models were used to evaluate the association between ONSD and ICP. RESULTS One hundred thirty-six measurements were obtained from 16 patients. ONSD was not significantly associated with ICP (p = 0.51). A ROC curve assessing ONSD to determine elevated ICP > 20 mmHg had an area under the curve of 0.52 (95%CI = 0.32-0.72). There was no difference in measurements obtained between the left and right ONSD at the same time (p = 0.82). CONCLUSIONS In conclusion, this study demonstrated no association between ONSD measurement and invasively monitored ICP in critically ill children.

Abstract
OBJECTIVES Electroencephalography (EEG) technologists commonly screen continuous EEG. Until now, the inter-rater agreement or sensitivity for important EEG findings has been unknown in this group. METHODS Twenty-nine EEG technologists and three clinical neurophysiologists interpreted 90 five-minute samples of pediatric critical care EEG. Inter-rater agreement was examined with Cohen's kappa and Fleiss' kappa for EEG findings. A gold-standard consensus agreement was developed for examining sensitivity and specificity for seizures or discontinuity. Kruskal-Wallis tests with Benjamani-Hochberg corrections for multiple comparisons were utilized to examine associations between correct scoring and certification status and years of experience. RESULTS Aggregate agreement was moderate for seizures and fair for EEG background continuity among EEG technologists. Individual agreement for seizures and continuity varied from slight to substantial. For individual EEG technologists, sensitivity for seizures ranged from 44 to 93% and sensitivity for continuity ranged from 81 to 100%. Raters with Certified Long Term Monitoring credentials were more likely to identify seizures correctly. SIGNIFICANCE This is the first study to evaluate inter-rater agreement and interpretation correctness among EEG technologists interpreting pediatric critical care EEG. EEG technologists demonstrated better aggregate agreement for seizure detection than other EEG findings, yet individual results and internal consistency varied widely. These data provide important insight into the common practice of utilizing EEG technologists for screening critical care EEG.

Abstract
OBJECTIVES Caregivers of infants with cystic fibrosis (CF) carry a heavy treatment burden for their child along with the inherent difficulties of raising an infant. This study investigated the impact of self-reported caregiver mental health diagnoses and social barriers during the 1st year of life on clinical outcomes. METHODS A retrospective chart review was conducted for infants seen in a large tertiary hospital CF clinic over a 5-year period. Baseline characteristics were collected, and documentation from physician and social work notes were reviewed. Demographics and clinical characteristics were compared by the presence or absence of self-reported mental health diagnoses, social barriers, and "emotional concern." RESULTS Analyses were conducted on 71 patients. Thirty-five percent of caregivers disclosed mental health diagnoses, 52% identified social barriers to care, and 55% reported feeling upset or fatigued. Having a caregiver with a self-reported mental health diagnosis was associated with tobacco smoke exposure (p < .001) and increased odds of hospitalizations (odds ratio [OR], 3.01; 95% confidence interval [CI], 1.49-6.06), emergency department/urgent care visits (OR, 3.17; 95% CI, 1.32-7.64), and longer lengths of stay (OR, 1.93; 95% CI, 1.69-2.20). Caregivers who expressed emotional concern had infants with significantly lower weight-for-length percentiles (p = .012). DISCUSSION Caregiver mental health and social barriers to care are important determinants to address as they may impact clinical outcomes in infants with CF. Identifying barriers and struggles early increases the likelihood that clinical teams can intervene and provide support. Further research into mental health and socioeconomic barriers faced by caregivers of infants with CF is crucial.

Abstract
BACKGROUND Age-dependent differences in clinical presentation and viral loads in infants and young children with respiratory syncytial virus (RSV) infection, and their correlation with disease severity are poorly defined. METHODS Previously healthy children <2 years old with mild (outpatients) and severe (inpatients) RSV infection were enrolled and viral loads measured by polymerase chain reaction in nasopharyngeal swabs. Patients were stratified by age in 0-<3, 3-6 and >6-24 months, and multivariable analyses were performed to identify clinical and viral factors associated with severe disease. RESULTS From 2014 to 2018, we enrolled 534 children with RSV infection, 130 outpatients with mild RSV infection and 404 inpatients with severe RSV disease. Median duration of illness was 4 days for both groups, yet viral loads were higher in outpatients than in inpatients (P < 0.001). In bivariate analyses, wheezing was more frequent in outpatients of older age (>3 months) than in inpatients (P < 0.01), while fever was more common in inpatients than outpatients (P < 0.01) and its frequency increased with age. Adjusted analyses confirmed that increased work of breathing and fever were consistently associated with hospitalization irrespective of age, while wheezing in infants >3 months, and higher RSV loads in children >6-24 months were independently associated with reduced disease severity. CONCLUSIONS Age had a significant impact defining the interactions among viral loads, specific clinical manifestations and disease severity in children with RSV infection. These observations highlight the importance of patient stratification when evaluating interventions against RSV.

Abstract
Abstract
Background
Despite the high burden associated with RSV infection in young children the factors that determine disease severity are not well understood. The objective of this study was to assess the association of mucosal cytokine profiles, RSV loads (VL) and RSV disease severity.
Methods
Single-center, prospective study in previously healthy infants with mild (outpatients; OP), moderate (inpatient-IP; ward) or severe (IP-PICU) RSV infection. Mid-turbinate swabs were obtained to measure VL by PCR, and cytokine concentrations (conc.) using a 13-plex panel that included type I (IFN-α2), II (IFN-γ), and III (IFN-λ2/λ3) interferons (IFN), and inflammatory cytokines. Multivariable analyses were performed to identify factors predictive of disease severity.
Results
From 2014 to 2019 we enrolled 219 infants: 78 with mild RSV infection (OP; median [IQR] age, 6 [3.4–10.5] mo.), 101 with moderate disease (3.5 [1.3–8.3] mo.), and 40 with severe disease (2.3 [1.5–5.7] mo.). Duration of symptoms at enrollment was 4 (3–5) days and comparable between OP and IP, yet RSV VL in OP were significantly higher than in IP (8.1 [7.4–8.6] vs 7.4 [6.4–8.1] log10 copies/mL; p< 0.01) with no differences between ward and PICU infants. Median conc. of IFN-α2, IFN-γ, and IFN-λ2/λ3 were significantly higher in OP vs IP irrespective of hospitalization unit (Table 1). IP-10 conc. were also higher in OP and in ward patients vs PICU patients (p< 0.0001) and were independently associated with lower odds of supplemental O2 needs (OR, 95% CI: 0.4 [0.22–0.69]; p< 0.01) and PICU admission (0.4 [0.23–0.67]; p=0.001). In addition, higher IFN-λ2/λ3 conc. were nearly associated with lower odds of prolonged O2 use (OR: 0.35 [0.11–1.07]; p=0.07), and prolonged hospitalization (OR: 0.42 [0.16–1.03]; p=0.06).
Conclusion
Infants with mild RSV infection had higher RSV VL and higher conc. of IP-10 and type-I, III IFN than those hospitalized with severe disease. These findings suggest that IP-10 and mucosal IFNs are associated with protection against severe RSV disease and could be used as biomarkers for patient stratification in the clinical setting.

Abstract
Abstract
Background
Differences in clinical presentation and viral loads according to age in young children with RSV, and their correlation with disease severity are poorly defined. The aim of this study was to define age-dependent the differences in demographic, clinical factors and viral loads between children < 2 years of age with mild RSV infection evaluated as outpatients versus those hospitalized with severe RSV infection.
Figure 1. Sign and Symptoms according to disease severity and age in infants with RSV infection. Most relevant signs and symptoms were stratified in outpatients (orange) vs inpatients (blue) by age in (A) < 3 months, (B) between 3 and 6 months, and (C) > 6 to 24 months of age. The Y axis represents the signs and symptoms in the two disease severity groups and the X axis the frequency of that specific symptom (%). Numbers next to bars represent the exact number of patients with that specific sign/symptom. Comparisons by Fisher exact test. Symbol (*) indicate significant 2-sided p values
Figure 2. Viral load differences according to age in infants with RSV infection. The Y axis represents RSV loads in log10 copies/mL and the X axis differences in viral loads in outpatients (orange) and inpatients (blue) in the three age groups. Comparisons by Mann Whitney test.
Methods
Previously healthy children < 2 years old with mild (outpatients) and severe (inpatients) RSV infection were enrolled and nasopharyngeal swabs were obtained for RSV typing and quantitation by real-time PCR. Patients were stratified by age (0-< 3, 3-6, and >6-24 months) and multivariable analyses were performed to identify clinical and viral factors associated with severe disease.
Results
From 2014-2018 we enrolled 534 children with RSV infection: 130 outpatients and 404 inpatients. Median duration of illness was 4 days for both groups, yet viral loads were higher in outpatients than inpatient in the three age groups (Fig 1). Wheezing was more frequent in outpatients of older age (>3 months) than in inpatients (p< 0.01), while fever was more common in inpatients that outpatients (p< 0.01) and increased with age (Fig 2). Adjusted analyses confirmed that increased work of breathing and fever were consistently associated with hospitalization irrespective of age, while wheezing in infants >3 months, and higher RSV loads in children >6-24 months were independently associated with reduced disease severity.
Conclusion
Age had a significant impact defining the interactions among viral loads, specific clinical manifestations and disease severity in children with RSV infection. These observations highlight the importance of patient stratification when evaluating interventions against RSV.

Natural History of Steroid-Treated Young Boys With Duchenne Muscular Dystrophy Using the NSAA, 100m, and Timed Functional Tests. Pediatr Neurol 2020; 113:15-20. [PMID: 32979653 DOI: 10.1016/j.pediatrneurol.2020.08.013] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/01/2020] [Revised: 08/17/2020] [Accepted: 08/19/2020] [Indexed: 12/15/2022]
Abstract
INTRODUCTION Clinical trials targeting younger cohorts of boys with Duchenne muscular dystrophy are necessary as earlier intervention may maximize treatment effect. Boys with Duchenne muscular dystrophy often have gross motor delays very early in life, and although they gain skills, they are on a lower trajectory than typical peers. Quantifying the natural rate of motor maturation in Duchenne muscular dystrophy from an early age permits identification of deviations from the expected trajectory related to treatment effects. METHODS The purpose of our study was to define the natural history in boys aged from ≥3 to <8 years using the North Star Ambulatory Assessment (NSAA), 100-meter timed test (100m), 10-meter walk/run (10m), time to rise (Rise), and 4-stair climb (4SC). Assessments were completed as standard of care during regularly scheduled clinic visits. RESULTS One hundred sixty-two boys with DMD aged 3.1 to 7.9 years on glucocorticoids were evaluated using one or more of the following tests as appropriate for age: NSAA (N = 158; 3.1-7.9 years), 100m (N = 131; 3.4-7.9 years), 10m (N = 162; 3.1-7.9 years), Rise (N = 160; 3.1-7.9 years), and 4SC (N = 153; 3.1-7.9 years). Longitudinal data are presented by age in a subcohort (N = 64). CONCLUSIONS Our study documents the baseline function of boys with DMD who are being treated with corticosteroids. These data will be useful to compare ongoing and future therapeutic intervention(s) for DMD.

Abstract
AIM To evaluate the properties of the Infant Motor Activity Log (IMAL), a caregiver-report for frequency and quality of use of more affected upper extremity in infants with neurological and functional impairments. METHOD This was a prospective cohort study of 66 children (34 females, 32 males) aged 6 to 24 months (mean age [SD] 13.7mo [5.3]) with neurological and functional impairments and a confirmed cerebral palsy diagnoses after 2 years, and 51 age-matched typically developing children. The IMAL was administered at baseline and 4 weeks later. Typically developing infants were tested with randomly assigned 'more affected' upper extremity. Psychometric properties were evaluated using Spearman's correlation coefficient, Cronbach's alpha, and Jonckheere-Terpstra tests. RESULTS In the children with impairments, the IMAL showed internal consistency (alpha≥0.88) for the How Well Scale (HWS) and How Often Scale (HOS). Test-retest reliability was 0.64 (HOS) and 0.70 (HWS), demonstrating stability over time. Correlation with Bayley Scales of Infant and Toddler Development, Third Edition more affected arm raw scores were 0.70 (HOS) and 0.72 (HWS) (p<0.001) demonstrating construct validity. Both scale scores decreased with increasing Gross Motor Function Classification System and Mini-Manual Ability Classification System (p<0.001) levels, supporting discriminative validity. Discrimination between typically developing infants and infants with impairments was high (HWS: area under the receiver operating characteristic curve [AUC] 0.96, 95% confidence interval [CI] 0.94-0.99 and HOS AUC=0.95, CI 0.92-0.99). INTERPRETATION The IMAL is a valid and reliable discriminative caregiver measure of upper limb performance and may complement measures of capacity in infants with neurological and functional impairments. WHAT THIS PAPER ADDS The Infant Motor Activity Log (IMAL) is a valid and reliable measure of caregiver perception of upper limb function. The IMAL fills a measurement gap for infant motor performance in children with impairments. The IMAL discriminates among motor function levels.

Abstract
OBJECTIVE Polyautoimmunity (PA) with systemic lupus erythematosus (SLE) is reported as a poor prognostic factor, but little is known about its effect in childhood-onset SLE (cSLE). We describe PA in cSLE within the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Legacy Registry and evaluate its association to lupus disease outcomes. METHODS CARRA Legacy Registry is the largest pediatric rheumatology registry that collected data at enrollment and every 6 months thereafter. We describe the co-occurrence of selected autoimmune disorders (autoimmune thyroid diseases, autoimmune hepatitis, celiac disease and type 1 diabetes mellitus) in cSLE. To assess outcomes, we studied measures of lupus disease activity, complications, and patient's quality of life (QoL). Comparisons by PA status were made using chi-square, Fisher's exact test, two-sample t-tests, Wilcoxon rank sum tests, and mixed effects models as appropriate. RESULTS 1285 patients met the American College of Rheumatology criteria for SLE. Of those, 388 (30%) had data on comorbidity. The prevalence of PA was 8.8%. Patients with PA reported more hospitalizations and aggressive immunotherapy use. SLEDAI and PGA scores improved over time, but did not differ by PA status. No significant differences were found in QoL measures or their trajectory over time by PA status. CONCLUSION In cSLE, PA is associated with more hospitalizations and aggressive immunotherapy use. Although lupus disease activity improved over time, patients' QoL neither improved over time nor differed by having other autoimmune disease. Prospective, case-control, long-term follow-up studies on cSLE are needed to validate our results.

Abstract
Chronic hepatitis C virus (HCV) infection is characterized by persistent high-level viremia and defective cellular immunity, including a lack of functional HCV-specific CD4+ T cells. We previously described an exceptional period of viral control that occurs in some chronically infected women after childbirth. Here, we investigated whether reduced HCV replication after pregnancy is associated with recovery of CD4+ T cell immunity. Class II tetramer analysis revealed significantly greater frequencies of circulating HCV-specific CD4+ T cells at 3 months postpartum in women with concurrent declines in viremia compared with those with stable viremia. These HCV-specific CD4+ T cells had an effector-memory phenotype. Inhibitory coreceptor expression on these cells corresponded to the degree of viral control. Circulating CD4+ T cells produced IL-2 and IFN-γ after HCV antigen stimulation, demonstrating Th1 functionality. These data provide direct evidence that the profound loss of HCV-specific CD4+ T cell help that results in chronic infection is reversible following pregnancy, and this recovery of CD4+ T cells is associated with at least transient control of persistent viral replication.

Hydrocortisone treatment is associated with a longer duration of MODS in pediatric patients with severe sepsis and immunoparalysis. CRITICAL CARE : THE OFFICIAL JOURNAL OF THE CRITICAL CARE FORUM 2020; 24:545.

Abstract
Background Severe critical illness-induced immune suppression, termed immunoparalysis, is associated with longer duration of organ dysfunction in septic children. mRNA studies have suggested differential benefit of hydrocortisone in septic children based on their immune phenotype, but this has not been shown using a functional readout of the immune response. This study represents a secondary analysis of a prospectively conducted immunophenotyping study of pediatric severe sepsis to test the hypothesis that hydrocortisone will be differentially associated with clinical outcomes in children with or without immunoparalysis. Methods Children with severe sepsis/septic shock underwent blood sampling within 48 h of sepsis onset. Immune function was measured by quantifying whole blood ex vivo LPS-induced TNFα production capacity, with a TNFα response < 200 pg/ml being diagnostic of immunoparalysis. The primary outcome measure was number of days in 14 with MODS. Univariate and multivariable negative binomial regression models were used to examine associations between hydrocortisone use, immune function, and duration of MODS. Results One hundred two children were enrolled (age 75 [6–160] months, 60% male). Thirty-one subjects received hydrocortisone and were more likely to be older (106 [52–184] vs 38 [3–153] months, p = 0.04), to have baseline immunocompromise (32 vs 8%, p = 0.006), to have higher PRISM III (13 [8–18] vs 7 [5–13], p = 0.0003) and vasoactive inotrope scores (20 [10–35] vs 10 [3–15], p = 0.0002) scores, and to have more MODS days (3 [1–9] vs 1 [0–3], p = 0.002). Thirty-three subjects had immunoparalysis (TNFα response 78 [52–141] vs 641 [418–1047] pg/ml, p < 0.0001). Hydrocortisone use was associated with longer duration of MODS in children with immunoparalysis after adjusting for covariables (aRR 3.7 [1.8–7.9], p = 0.0006) whereas no association with MODS duration was seen in children without immunoparalysis (aRR 1.2 [0.6–2.3], p = 0.67). Conclusion Hydrocortisone use was independently associated with longer duration of MODS in septic children with immunoparalysis but not in those with more robust immune function. Prospective clinical trials using a priori immunophenotyping are needed to understand optimal hydrocortisone strategies in this population.

Abstract
BACKGROUND AND OBJECTIVES Early diagnosis of cerebral palsy (CP) is critical in obtaining evidence-based interventions when plasticity is greatest. In 2017, international guidelines for early detection of CP were published on the basis of a systematic review of evidence. Our study aim was to reduce the age at CP diagnosis throughout a network of 5 diverse US high-risk infant follow-up programs through consistent implementation of these guidelines. METHODS The study leveraged plan-do-study-act and Lean methodologies. The primary outcome was age at CP diagnosis. Data were acquired during the corresponding 9-month baseline and quarterly throughout study. Balancing measures were clinic no-show rates and parent perception of the diagnosis visit. Clinic teams conducted strengths, weaknesses, opportunities, and threats analyses, process flow evaluations, standardized assessments training, and parent questionnaires. Performance of a 3- to 4-month clinic visit was a critical process step because it included a Hammersmith Infant Neurologic Examination, a General Movements Assessment, and standardized assessments of motor function. RESULTS The age at CP diagnosis decreased from a weighted average of 19.5 (95% confidence interval 16.2 to 22.8) to 9.5 months (95% confidence interval 4.5 to 14.6), with P = .008; 3- to 4-month visits per site increased from the median (interquartile range) 14 (5.2-73.7) to 54 (34.5-152.0), with P < .001; and no-show rates were not different. Parent questionnaires revealed positive provider perception with improvement opportunities for information content and understandability. CONCLUSIONS Large-scale implementation of international guidelines for early detection of CP is feasible in diverse high-risk infant follow-up clinics. The initiative was received positively by families and without adversely affecting clinic operational flow. Additional parent support and education are necessary.

Abstract
Background The association between respiratory syncytial virus (RSV) loads and clinical outcomes in children remains to be defined. In most studies, viral loads (VL) were evaluated in hospitalized children and at a single time-point. We investigated the relationship between VLs and disease severity in both outpatients and inpatients with RSV infection. Methods We enrolled previously healthy children with RSV infection. Disease severity was defined by level of care (outpatients vs ward vs pediatric intensive care unit [PICU]), and a clinical disease severity score (CDSS). Nasopharyngeal VLs by polymerase chain reaction and CDSS were measured at enrollment and daily in inpatients. VL decay according to disease severity was analyzed using linear mixed modeling. Results From February 2015 to March 2017, we enrolled 150 infants: 39 outpatients and 111 inpatients. VLs were higher in outpatients than in age-matched inpatients. Among inpatients, initial VLs were comparable in ward and PICU patients, and preceded the peak CDSS. However, after excluding infants treated with steroids, those hospitalized in the ward had higher VLs than infants requiring PICU care (P < .001). Dynamic analyses showed that VL decay was delayed in PICU patients, especially in those treated with steroids. Conclusions Higher VLs at presentation and a faster and consistent VL decline were both associated with less severe RSV disease in children. Summary Infants with less severe respiratory syncytial virus (RSV) disease had higher viral loads (VL) at presentation, and faster and consistent VL decline. Conversely, VL decay and overall viral exposure were prolonged and higher in infants severe RSV disease receiving steroids.

Abstract
PURPOSE Abusive head trauma (AHT) is the leading cause of fatal head injuries for children under 2 years. The objective was to evaluate, using transcranial Doppler ultrasound (TCD), whether children with AHT have a similar neurovascular response to injury compared with children without AHT. METHODS Retrospective sub-analysis of previously prospectively acquired data in a pediatric intensive care unit in a level 1 trauma hospital. TCD was performed daily until hospital day 8, discharge, or death. Neurologic outcome was assessed using the Glasgow Outcome Scale Extended (GOS-E Peds) at 1 month from initial injury. RESULTS Sixty-nine children aged 1 day to 17 years with moderate-to-severe traumatic brain injury were enrolled. Fifteen children suffered AHT and 54 had no suspicion for AHT. Fifteen children with AHT underwent 80 serial TCD examinations; 54 children without AHT underwent 308 exams. After standardization for age and gender normative values, there was no statistically significant difference in mean cerebral blood flow velocity of the middle cerebral artery (VMCA) between children with and without AHT. There was no difference in the incidence of extreme cerebral blood flow velocity (CBFV, greater or less than 2 standard deviations from normative value) between groups. Within the AHT group, there were no statistically significant differences in VMCA between children with a favorable (GOS-E Peds 1-4) versus unfavorable neurologic outcome (GOS-E Peds 5-8). CONCLUSION Children with AHT have no significant differences in VMCA or percentage of extreme CBFV in the middle cerebral artery compared to with those without AHT.

Abstract
Aim: To define a developmental trajectory in infants with neonatal opioid withdrawal syndrome (NOWS) and determine whether the impacted developmental domain varies with the type of antenatal exposure. Methods: We performed a retrospective cohort study of infants treated pharmacologically for NOWS and assessed using a standardized schedule for follow-up visits. We compared outcomes of the study population to published norms using one-sample t-tests. Multivariable models examined associations with exposures in addition to opioids. Results: In our cohort of 285 infants with 9-12-months testing, 164 (55.7%) were seen at 3-4 months, and 125 (44%), at 15-18 months. The majority (58%) had intrauterine drug exposures in addition to opioids. Neurodevelopmental scores of infants with NOWS at 3-4 and 9-12 months were not different from published norms. Cognitive and language scores at 15-18 months were worse than published norms. Male sex, older maternal age, and additional barbiturate or alcohol exposure were associated with worse outcomes. Conclusion: Infants with pharmacologically treated NOWS had development similar to unexposed infants during the 1st year but worse cognitive and language scores during the 2nd year. These data support the need for a prospective follow-up of large cohorts of infants with NOWS, with systematic assessments and an evaluation of contributing factors.

Abstract
Background Both psychosocial and socioeconomic risk factors contribute to poor glycemic control (GC). Previous research has identified that diabetes care behaviors are generally 'set' by late childhood, further highlighting the importance of psychosocial screening and intervention in the early course of disease management. The purpose of the current study was to determine whether this brief risk assessment tool is associated with GC and acute health care (HC) utilization, and to evaluate the discriminatory utility of the tool for predicting poor outcomes. Methods This was a retrospective cohort design in which we compared risk assessment scores with health outcomes at 6, 12, and 18 months after new-onset type 1 diabetes diagnosis for 158 patients between 2015 and 2017. The two primary outcome variables were GC and acute HC utilization. Results Our data demonstrate that the greatest utility of the tool is for predicting increased acute HC utilization. It was most useful in differentiating between patients with vs. without any acute HC utilization, with excellent discriminatory ability (area under the receiver operator characteristic curve [AUC] = 0.93), sensitivity (90%), and specificity (97%). Conclusions Knowledge of the risk category in addition to identification of individual risk factors within each domain allows for not only clear treatment pathways but also individualized interventions. The risk assessment tool was less effective at differentiating patients with poor GC; however, the tool did have high specificity (83%) for predicting poor GC at 18 months which suggests that the tool may also be useful for predicting patients at risk for poor GC.

Abstract
OBJECTIVES Seizure action plans help patients and caregivers better self-manage their epilepsy. We hypothesized that providing pediatric patients and their caregivers with a seizure action plan would reduce unplanned health care utilization and decrease the impact of epilepsy. METHODS We developed a seizure action plan for use in pediatric epilepsy patients. A prospective cohort was randomly assigned to receive a seizure action plan in addition to standard epilepsy care or to standard epilepsy care alone. All caregivers were surveyed using the Modified Impact on Families (MIF) questionnaire at enrollment, 3 months, and 12 months. Health care utilization measures and Modified Impact on Families questionnaire scores were compared between the 2 groups. RESULTS Fifty-four patients received a seizure action plan and standard care, whereas 48 received standard care alone. The groups had similar demographics. There was a significantly higher proportion of overall clinic appointment no shows in the standard care group vs the seizure action plan group (P = .04); however, other significant differences in health care utilization were not found. Among patients with low seizure frequency (12 or fewer seizures per year), Seizure comfort scores on the Modified Impact on Families questionnaire were significantly higher at 12 months among the seizure action plan group compared to the standard care group. SIGNIFICANCE Caregivers for patients with epilepsy receiving a seizure action plan were more comfortable regarding seizure care and missed fewer appointments. However, differences in health care utilization were not present. The seizure action plan appears to have more impact in patients who experience lower seizure frequencies. Further studies evaluating the impact as well as assessing caregivers' perceptions of the seizure action plan using a larger sample are needed.

Abstract
Background Scientific advances have improved longevity in cystic fibrosis (CF) patients and many of these patients can expect to experience age-related gastrointestinal co-morbidities. We aimed to assess the extent to which age might impact gastroesophageal reflux (GER) in patients with CF. Methods Our esophageal pH-multichannel intraluminal impedance monitoring database was searched for tracings belonging to CF patients ≥2 years old without prior fundoplication and not taking anti-reflux medications immediately prior (within 7 days) and during the study. Tracings were retrospectively analyzed; Impedance and pH variables were evaluated with respect to age and pulmonary function. Results Twenty-eight patients were enrolled; 16 children (3.1-17.7 years) and 12 adults (18.2-48.9 years). Among pH probe parameters, correlation analysis showed DeMeester score (P=0.011) and number of acid reflux events lasting >5 minutes (P=0.047) to be significantly correlated with age. Age was not significantly correlated with any of the impedance parameters. Age was negatively correlated with baseline impedance (BI) in the distal esophagus (r=-0.424, P=0.023) and BI was negatively correlated with several pH parameters, including reflux index (r=-0.553, P=0.002), number of total acid reflux events (r=-0.576, P=0.001), number of acid reflux events lasting >5 minutes (r=-0.534, P=0.003), and DeMeester score (r=-0.510, P=0.006). Pulmonary function (percent predicted forced expiratory volume in one minute; ppFEV1) was negatively correlated with age (r=-0.494, P=0.0007). The interaction of age and ppFEV1 and any of the reflux parameters, however, was not significant (P>0.05); the strongest evidence for an interaction was found for the number of acid reflux events reaching the proximal esophagus, but this interaction still did not reach statistical significance (P=0.070). Conclusions In a small cohort, we found evidence that age may be associated with increased acid exposure and that both age and increased acid exposure are associated with reduced BI in the distal esophagus. The negative relationship between pulmonary function and age in our cohort is not related to GER. This pilot study supports the need for esophageal assessment and treatment of GER as standard components of clinical care for an aging CF population.
