RESUMEN
BACKGROUND: Asymptomatic SARS-CoV-2 infection in children is highly prevalent but its acute and chronic implications have been minimally described. METHODS: In this controlled case-ascertained household transmission study, we recruited asymptomatic children <18 years with SARS-CoV-2 nucleic acid testing performed at 12 tertiary care pediatric institutions in Canada and the United States. We attempted to recruit all test-positive children and 1 to 3 test-negative, site-matched controls. After 14 days' follow-up we assessed the clinical (ie, symptomatic) and combined (ie, test-positive, or symptomatic) secondary attack rates (SARs) among household contacts. Additionally, post-COVID-19 condition (PCC) was assessed in SARS-CoV-2-positive participating children after 90 days' follow-up. RESULTS: A total of 111 test-positive and 256 SARS-CoV-2 test-negative asymptomatic children were enrolled between January 2021 and April 2022. After 14 days, excluding households with co-primary cases, the clinical SAR among household contacts of SARS-CoV-2-positive and -negative index children was 10.6% (19/179; 95% CI: 6.5%-16.1%) and 2.0% (13/663; 95% CI: 1.0%-3.3%), respectively (relative risk = 5.4; 95% CI: 2.7-10.7). In households with a SARS-CoV-2-positive index child, age <5 years, being pre-symptomatic (ie, developed symptoms after test), and testing positive during Omicron and Delta circulation periods (vs earlier) were associated with increased clinical and combined SARs among household contacts. Among 77 asymptomatic SARS-CoV-2-infected children with 90-day follow-up, 6 (7.8%; 95% CI: 2.9%-16.2%) reported PCC. CONCLUSIONS: Asymptomatic SARS-CoV-2-infected children, especially those <5 years, are important contributors to household transmission, with 1 in 10 exposed household contacts developing symptomatic illness within 14 days. Asymptomatic SARS-CoV-2-infected children may develop PCC.

OBJECTIVE: To examine differences in hospital admission and diagnostic evaluation for febrile seizure by race and ethnicity. STUDY DESIGN: We conducted a cross-sectional study among children 6 months to 6 years with simple or complex febrile seizure between January 1, 2016, and December 31, 2021, using data from the Pediatric Health Information System. The primary outcome was hospital admission. Secondary outcomes included the proportion of encounters with neuroimaging or lumbar puncture. We used mixed-effects logistic regression model with random intercept for hospital and patient to estimate the association between outcomes and race and ethnicity after adjusting for covariates, including seizure type. RESULTS: In total, 94â884 encounters were included. Most encounters occurred among children of non-Hispanic White (37.0%), Black (23.9%), and Hispanic/Latino (24.6%) race and ethnicity. Black and Hispanic/Latino children had 29% (aOR 0.71; 95% CI 0.66-0.75) and 26% (aOR 0.74; 95% CI 0.69-0.80) lower odds of hospital admission compared with non-Hispanic White children, respectively. Black and Hispanic/Latino children had 21% (aOR 0.79; 95% CI 0.73-0.86) and 22% (aOR 0.78; 95% CI 0.71-0.85) lower adjusted odds of neuroimaging compared with non-Hispanic White children. For complex febrile seizure, the adjusted odds of lumbar puncture was significantly greater among Asian children (aOR 2.12; 95% CI 1.19-3.77) compared with non-Hispanic White children. There were no racial differences in the odds of lumbar puncture for simple febrile seizure. CONCLUSIONS: Compared with non-Hispanic White children, Black and Hispanic/Latino children with febrile seizures are less likely to be hospitalized or receive neuroimaging.

OBJECTIVES: To describe trends in creatinine and acute kidney injury (AKI) in children who present with diabetic ketoacidosis (DKA) and receive low versus high intravenous (IV) fluid bolus volumes. Further, to determine whether resolution of AKI is hastened by low versus high bolus volumes. METHODS: We conducted an observational retrospective cohort study between January 2012 and March 2020 among children ≤21 years presenting with DKA. Acute kidney injury was defined by the Kidney Disease/Improving Global Outcomes creatinine criteria, using the Schwartz estimating equation to calculate an expected baseline creatinine. Bolus volume was categorized as low (<15 mL/kg) or high (≥15 mL/kg). Generalized additive mixed models were used to model trends of creatinine ratios. Estimated mean creatinine ratios and differences by bolus volumes were assessed at the time of bolus, and 12, 24, 36, 48 hours. Cox proportional hazard models were used to estimate the association between resolution of AKI and bolus volume after adjustment for confounders. RESULTS: We identified 708 eligible encounters with DKA, of which 169 (23.9%) had AKI at presentation and 10 (1.4%) developed AKI after hospitalization. Comparing patients who received low versus high bolus volumes, the proportion of encounters with AKI on presentation was similar (P = 0.364) as was the mean difference in creatinine ratios over time. In adjusted analysis, treatment with high IV fluid bolus volume was only associated with a 6.2% faster resolution of AKI (hazard ratio, 1.062; 95% confidence interval, 0.61-1.87). CONCLUSIONS: Intravenous fluid bolus volume was not associated with resolution of AKI in our cohort of children with DKA.

OBJECTIVES: Our objectives were to quantify pain experienced by young children undergoing facial laceration repair and identify factors associated with low procedural pain scores. METHODS: We conducted a prospective cohort study of children's distress among a convenience sample of children aged 1 to 5 years undergoing facial or scalp laceration repair in 2 pediatric emergency departments. We reviewed video recordings and documented pain scores at 15-second intervals using the Face, Leg, Activity, Cry, Consolability-Revised (FLACC-r) scale. We dichotomized FLACC-r into low/high scores (≤3 and >3) to evaluate practice variables. RESULTS: We included 11,474 FLACC-r observations from 258 procedures in the analysis. Two-thirds of 3- to 5-year-olds completed their laceration repair without the use of restraint, sedation, or anxiolytics. Mean distress scores were low (≤2.5 out of 10) across all procedure phases for 2- to 5-year-old patients. One-year-old patients experienced significantly more distress than their older counterparts (mean ≤4.2 out of 10). Odds of having low FLACC scores (≤3) were greater for patients with an expert clinician (adjusted odds ratio [aOR]: 1.72; 95% confidence interval [CI], 1.05-2.84). Wound infiltration (aOR, 0.35; 95% CI, 0.13-0.93), patient observation of a needle (aOR, 0.21; 95% CI, 0.14-0.33), and restraint (aOR, 0.04; 95% CI, 0.02-0.06) were negatively associated with low FLACC score. CONCLUSION: The majority of 3- to 5-year-old patients were able to undergo facial laceration repair without restraint, sedation, or anxiolytics and with low mean distress scores. Our findings suggest that children's risk of experiencing moderate and severe distress during facial and scalp laceration repair may be reduced by prioritizing wound closure by expert-level clinicians, ensuring effective lidocaine-epinephrine-tetracaine application, avoiding restraint, and concealing needles from patient view.

OBJECTIVES: To determine whether patients with sickle cell disease (SCD) who present to the emergency department (ED) with vasoocclusive pain crises (VOC), and have coexisting mental health (MH) diagnoses, are more likely to have increased health care utilization and more frequent opioid administration compared with those without coexisting MH conditions. METHODS: This is a retrospective study of patients aged 5 to 18 years with SCD who presented to a tertiary care ED with a primary complaint of VOC between January 1, 2013, and December 31, 2017. We excluded patients with sickle cell trait and without a pain management plan in the electronic medical record. Outcomes included ED length of stay (LOS), admission rate, and opioid administration in the ED. Morphine equivalents were used to standardize opioid dosing. Mann-Whitney U and χ2 tests were used for univariate analysis. Multivariable logistic was performed for categorical and continuous outcomes, respectively, after adjusting for confounding factors. RESULTS: We identified 978 encounters. We excluded 196 without a pain management plan and one with inaccurate ED LOS, resulting in 781 encounters (148 patients) for analysis. Coexisting MH diagnoses were present in 75.0% of encounters, with anxiety (83.0%) and depressive disorders (55.9%) being most common. Compared with SCD patients without coexisting MH diagnoses, those with coexisting MH diagnoses had significantly longer ED LOS (252 ± 139 minutes vs 232 ± 145 minutes, P = 0.03), longer median hospital LOS (1.4 ± 3.2 days vs 0.3 ± 2.4 days, P < 0.001) in univariate analyses, but these differences were no longer significant in adjusted regression models. Patients with coexisting MH diagnoses had higher frequency of opioid administration in the ED (85.6% vs 71.4%, P < 0.0001) and higher odds of receiving opioids (adjusted odds ratio, 2.07; 95% confidence interval, 1.28-3.33). CONCLUSIONS: Patients with SCD and coexisting MH diagnoses presenting with VOC have greater odds of receiving opioids compared with patients with SCD without coexisting MH diagnoses. Our results indicate a need for more MH resources in this vulnerable population and may help guide future management strategies.

OBJECTIVES: Adverse childhood experiences (ACEs) including physical, emotional, or sexual abuse; neglect; and/or exposure to household instability have been associated with adult emergency department utilization, but the impact of parental ACEs on pediatric emergency department (PED) utilization has not been studied. The primary aim was to determine if parental ACEs impact resource utilization as measured by (1) frequency of PED utilization, (2) acuity of PED visits, and (3) 72-hour PED return rates. The secondary aim was to determine if resilience interacts with the impact of parental ACEs on PED utilization. METHODS: This study is a cross-sectional survey using previously validated measures of ACEs, resiliency, and social determinants of health screening. Surveys were administered from October 17, 2019, to November 27, 2019, via iPad by research assistants in our institution's PEDs. Survey responses were linked to data abstracted from the electronic health record. Descriptive statistics were used to characterize our study population. Pearson correlation was used to identify correlation between ACEs, social determinants of health, and PED utilization measures. RESULTS: A total of 251 parents had complete data. Parental ACEs were positively associated with frequency of PED visits (incidence rate ratio, 1.013). In addition, high levels of parental resilience attenuated the association between parental ACEs and the number of severe acuity visits and were associated with fewer 72-hour return visits (incidence rate ratio, 0.49). CONCLUSIONS: Parental ACEs appear to be positively associated with frequency of PED utilization and inversely associated with higher-acuity PED visits and parental resiliency.

OBJECTIVE: The aim of the study was to compare quality indicators, including frequency of acute surgical and emergent interventions, and resource utilization before and after American College of Surgeons (ACS) level I trauma verification among children with moderate or severe traumatic brain injury (TBI). METHODS: This is a retrospective review of patients younger than 18 years treated for moderate or severe TBI, as determined by International Classification of Disease codes. Our institution obtained ACS level I trauma verification in 2013. Outcomes during the pre-ACS (June 2003-May 2008), interim (June 2008-May 2013), and post-ACS (June 2013-May 2018) periods were compared via nonparametric tests. Tests for linear trend were conducted using Cochran-Armitage tests for categorical data and by linear regression for continuous variables. RESULTS: There were 677 children with moderate or severe TBIs (pre-ACS, 125; interim, 198; post-ACS, 354). Frequency of any surgical intervention increased significantly in the post-ACS period (12.2%) compared with interim (5.1%) and pre-ACS periods (5.6%, P = 0.007). More children in the post-ACS period required intracranial pressure monitoring (P = 0.017), external ventricular drain placement (P = 0.003), or endotracheal intubation (P = 0.001) compared with interim and pre-ACS periods. There was no significant change in time to operating room (P = 0.514), frequency of decompression (P = 0.096), or time to decompression (P = 0.788) between study periods. The median time to head CT decreased significantly in the post-ACS period (26 minutes; interquartile range [IQR], 9-60) compared with interim (36 minutes; IQR, 21-69) and pre-ACS periods (53 minutes; IQR, 36-89; P < 0.001). Frequency of repeat head computed tomography decreased significantly in the post-ACS period (30.2%) compared with interim (56.1%) and pre-ACS periods (64.0%, Ptrend = 0.044). CONCLUSIONS: Transition to an ACS level I trauma verification was associated with improvements in quality indicators for children with moderate or severe TBI.

OBJECTIVES: The aim of this study was to determine the accuracy and interrater reliability of (1) point-of-care ultrasound (POCUS) image interpretation for identification of intussusception and (2) reliability of secondary signs associated with intussusception among experts compared with novice POCUS reviewers. METHODS: We conducted a planned secondary analysis of a prospective, convenience sample of children aged 3 months to 6 years who were evaluated with POCUS for intussusception across 17 international pediatric emergency departments between October 2018 and December 2020. A random sample of 100 POCUS examinations was reviewed by novice and expert POCUS reviewers. The primary outcome was identification of the presence or absence of intussusception. Secondary outcomes included intussusception size and the presence of trapped free fluid or echogenic foci. Accuracy was summarized using sensitivity and specificity, which were estimated via generalized mixed effects logistic regression. Interrater reliability was summarized via Light's κ statistics with bootstrapped standard errors (SEs). Accuracy and reliability of expert and novice POCUS reviewers were compared. RESULTS: Eighteen expert and 16 novice POCUS reviewers completed the reviews. The average expert sensitivity was 94.5% (95% confidence interval [CI], 88.6-97.5), and the specificity was 94.3% (95% CI, 90.3-96.7), significantly higher than the average novice sensitivity of 84.7% (95% CI, 74.3-91.4) and specificity of 80.4% (95% CI, 72.4, 86.7). κ was significantly greater for expert (0.679, SE 0.039) compared with novice POCUS reviewers (0.424, SE 0.044; difference 0.256, SE 0.033). For our secondary outcome measure of intussusception size, κ was significantly greater for experts (0.661, SE 0.038) compared with novices (0.397, SE 0.041; difference 0.264, SE 0.029). Interrater reliability was weak for expert and minimal for novice reviewers regarding the detection of trapped free fluid and echogenic foci. CONCLUSIONS: Expert POCUS reviewers demonstrate high accuracy and moderate interrater reliability when identifying intussusception via image interpretation and perform better than novice reviewers.

OBJECTIVE: To assess the performance of a hemolytic uremic syndrome (HUS) severity score among children with Shiga toxin-producing Escherichia coli (STEC) infections and HUS by stratifying them according to their risk of adverse events. The score has not been previously evaluated in a North American acute care setting. STUDY DESIGN: We reviewed medical records of children <18 years old infected with STEC and treated in 1 of 38 participating emergency departments in North America between 2011 and 2015. The HUS severity score (hemoglobin [g/dL] plus 2-times serum creatinine [mg/dL]) was calculated using first available laboratory results. Children with scores >13 were designated as high-risk. We assessed score performance to predict severe adverse events (ie, dialysis, neurologic complication, respiratory failure, and death) using discrimination and net benefit (ie, threshold probability), with subgroup analyses by age and day-of-illness. RESULTS: A total of 167 children had HUS, of whom 92.8% (155/167) had relevant data to calculate the score; 60.6% (94/155) experienced a severe adverse event. Discrimination was acceptable overall (area under the curve 0.71, 95% CI 0.63-0.79) and better among children <5 years old (area under the curve 0.77, 95% CI 0.68-0.87). For children <5 years, greatest net benefit was achieved for a threshold probability >26%. CONCLUSIONS: The HUS severity score was able to discriminate between high- and low-risk children <5 years old with STEC-associated HUS at a statistically acceptable level; however, it did not appear to provide clinical benefit at a meaningful risk threshold.

STUDY OBJECTIVE: To determine the diagnostic accuracy of point-of-care ultrasound (POCUS) performed by experienced clinician sonologists compared to radiology-performed ultrasound (RADUS) for detection of clinically important intussusception, defined as intussusception requiring radiographic or surgical reduction. METHODS: We conducted a multicenter, noninferiority, observational study among a convenience sample of children aged 3 months to 6 years treated in tertiary care emergency departments across North and Central America, Europe, and Australia. The primary outcome was diagnostic accuracy of POCUS and RADUS with respect to clinically important intussusception. Sample size was determined using a 4-percentage-point noninferiority margin for the absolute difference in accuracy. Secondary outcomes included agreement between POCUS and RADUS for identification of secondary sonographic findings. RESULTS: The analysis included 256 children across 17 sites (35 sonologists). Of the 256 children, 58 (22.7%) had clinically important intussusception. POCUS identified 60 (23.4%) children with clinically important intussusception. The diagnostic accuracy of POCUS was 97.7% (95% confidence interval [CI] 94.9% to 99.0%), compared to 99.3% (95% CI 96.8% to 99.9%) for RADUS. The absolute difference between the accuracy of RADUS and that of POCUS was 1.5 percentage points (95% CI -0.6 to 3.6). Sensitivity for POCUS was 96.6% (95% CI 87.2% to 99.1%), and specificity was 98.0% (95% CI 94.7% to 99.2%). Agreement was high between POCUS and RADUS for identification of trapped free fluid (83.3%, n=40/48) and decreased color Doppler signal (95.7%, n=22/23). CONCLUSION: Our findings suggest that the diagnostic accuracy of POCUS performed by experienced clinician sonologists may be noninferior to that of RADUS for detection of clinically important intussusception. Given the limitations of convenience sampling and spectrum bias, a larger randomized controlled trial is warranted.

Diabetic ketoacidosis (DKA) occurs frequently among children and adolescents with type 1 diabetes. Although a number of complications may occur during episodes of DKA, significant cardiac arrhythmias are uncommon. We present the case of an adolescent who presented with severe DKA and wide complex tachycardia that was unresponsive to multiple doses of adenosine and ultimately required synchronized cardioversion. This case reminds the clinician of the importance of cardiac monitoring in children with DKA, particularly in the setting of hyperkalemia.

OBJECTIVES: Our primary objective was to describe emergency department (ED) presentation, treatment, and outcomes for children after hematopoietic cell transplantation (HCT). Our secondary objective was to identify factors associated with serious infection in this population. METHODS: This is a retrospective review of HCT patients who presented to our university children's hospital ED from January 1, 2011, to June 30, 2013. Emergency department presentation, treatment, and outcomes were described. Descriptive statistics were used to compare children with definite serious infection with those without serious infection. Multiple binary logistic regression was performed for risk factors associated with definite serious infection. RESULTS: Fifty-four HCT patients (132 encounters) presented to our ED. Most were transplanted for a malignant (46%) or metabolic (36%) diagnosis and were recipients of bone marrow (51%) or umbilical cord blood (45%). Fever was the most common complaint (25%). Emergency department laboratory (64%) or imaging (58%) studies were frequently obtained. Admission was common (n = 70/132, 53%), with 79% (n = 55) of admissions to intensive care or bone marrow transplant units. Thirty-five encounters had definite serious infection, 5 had probable serious infection, and 92 had no serious infection. Fever (P < 0.001) and high-risk white blood cell (WBC) count of less than 5 or greater than 15 k/µL (P < 0.001) were associated with definite serious infection. Fever (odds ratio = 8.84, 95% confidence interval = 2.92-26.73) and high-risk WBC (odds ratio = 6.67, 95% confidence interval = 2.24-19.89) remained significantly associated with definite serious infection in our regression model. CONCLUSIONS: Children presenting to the ED after HCT require extensive support and resources, with more than half requiring admission. Fever and high-risk WBC are associated with serious infection.

OBJECTIVE: The aims of this study were to describe the use of Ringer's lactate (LR) or normal saline (NS) for resuscitation among children with diabetic ketoacidosis (DKA) and compare the effect of fluid type on cost, length of stay, and rate of cerebral edema (CE). METHODS: This is a retrospective study of 49,737 children aged 0 to 17 years with DKA between January 1, 2005, and September 30, 2015, using data from the Pediatric Health Information System. Treatment with LR or NS was identified. Our primary outcomes were total adjusted cost and length of stay. Our secondary outcome was CE rate per 1000 episodes. RESULTS: The majority of patients were treated with NS (n = 43,841 [88%]) compared with LR (n = 1762 [4%]) or both NS and LR (n = 4134 [8%]). Hospital-year-specific practice patterns were used to investigate the effect of fluid type across resuscitation fluid groups. Total adjusted cost was $1160 less (95% confidence interval, -1468 to -852), or -14.2%, for cases with any episode of LR compared with NS only. Length of stay was not different across groups. The rate of cerebral edema per 1000 episodes was 12.7 for cases with any episode of LR compared with 34.6 NS only (difference, -21.9; 95% confidence interval, -30.4 to -13.3). CONCLUSIONS: Ringer's lactate was infrequently used for resuscitation of pediatric DKA patients. However, resuscitation with LR compared with NS was associated with lower total cost and rates of CE. Further investigation using patient-level clinical and laboratory data is needed to evaluate factors that drive cost and risk of CE development with each fluid.

BACKGROUND: Shiga toxin-producing Escherichia coli (STEC) infections are leading causes of pediatric acute renal failure. Identifying hemolytic uremic syndrome (HUS) risk factors is needed to guide care. METHODS: We conducted a multicenter, historical cohort study to identify features associated with development of HUS (primary outcome) and need for renal replacement therapy (RRT) (secondary outcome) in STEC-infected children without HUS at initial presentation. Children aged <18 years who submitted STEC-positive specimens between January 2011 and December 2015 at a participating study institution were eligible. RESULTS: Of 927 STEC-infected children, 41 (4.4%) had HUS at presentation; of the remaining 886, 126 (14.2%) developed HUS. Predictors (all shown as odds ratio [OR] with 95% confidence interval [CI]) of HUS included younger age (0.77 [.69-.85] per year), leukocyte count ≥13.0 × 103/µL (2.54 [1.42-4.54]), higher hematocrit (1.83 [1.21-2.77] per 5% increase) and serum creatinine (10.82 [1.49-78.69] per 1 mg/dL increase), platelet count <250 × 103/µL (1.92 [1.02-3.60]), lower serum sodium (1.12 [1.02-1.23 per 1 mmol/L decrease), and intravenous fluid administration initiated ≥4 days following diarrhea onset (2.50 [1.14-5.46]). A longer interval from diarrhea onset to index visit was associated with reduced HUS risk (OR, 0.70 [95% CI, .54-.90]). RRT predictors (all shown as OR [95% CI]) included female sex (2.27 [1.14-4.50]), younger age (0.83 [.74-.92] per year), lower serum sodium (1.15 [1.04-1.27] per mmol/L decrease), higher leukocyte count ≥13.0 × 103/µL (2.35 [1.17-4.72]) and creatinine (7.75 [1.20-50.16] per 1 mg/dL increase) concentrations, and initial intravenous fluid administration ≥4 days following diarrhea onset (2.71 [1.18-6.21]). CONCLUSIONS: The complex nature of STEC infection renders predicting its course a challenge. Risk factors we identified highlight the importance of avoiding dehydration and performing close clinical and laboratory monitoring.

OBJECTIVES: The goal of this study was to evaluate trends in medical claim submissions for limited ultrasound studies performed (1) during emergency department (ED) encounters and (2) by ED providers compared to radiologists. METHODS: We conducted a retrospective, descriptive study using medical claims data from Medica Health Plans from January 1, 2011 to December 31, 2015. Current procedural terminology codes were abstracted for limited ultrasound applications performed during an ED visit and further stratified by studies performed by ED providers compared with radiologists. We excluded claims for which we could not determine provider specialty. RESULTS: We identified 42,576 encounters with limited US claims, of which, 32,666 were submitted by ED providers (N = 9649) or radiologists (N = 23,017). Among ED providers, there was a significant linear increase in the annual number of claims for retroperitoneal (P < .001) and nonlinear increases for thoracic, soft tissue, cardiac, transvaginal genitourinary (GU) and transabdominal GU claims (all P < .001). Compared with radiologists, there was a linear increase in the annual proportion of claims submitted for retroperitoneal (P = .023), transabdominal GU (P = .003), and transvaginal GU (P < .001) studies by ED providers. There was a nonlinear decrease in the annual proportion of limited abdomen claims (P < .001) submitted by ED providers compared with radiologists. CONCLUSIONS: Using data from a large health plan provider, we show that medical claims for many limited ultrasound studies are increasing among ED providers. Compared with radiologists, ED providers are increasingly submitting claims for retroperitoneal, soft tissue, and transabdominal GU studies.

We present a case of a child who presented with neck swelling and was ultimately diagnosed with lymphoma after an internal jugular vein thrombosis was discovered by point-of-care ultrasound. The use of point-of-care ultrasound enabled thrombus detection, which prompted further evaluation and treatment.

OBJECTIVE: There are limited data regarding concussion among youth skiers and snowboarders. The objective of this study was to examine the frequency of concussion among helmeted and unhelmeted youth skiers and snowboarders presenting to trauma centers. METHODS: Subjects 18 years or younger with a ski- or snowboard-related injury were studied using data from the National Trauma Data Bank from 2009 to 2010. We further selected those with head/neck injuries and stratified based on helmet status. Concussive injuries were identified from International Classification of Diseases, 9th Revision codes. Severity analysis was based on the Glasgow Coma Scale and Injury Severity Score. RESULTS: A total of 1001 subjects met inclusion criteria with 678 subjects having documented helmet status. Subjects 12 years or younger were more likely to use helmets compared to 13-18 year-olds (odds ratio, 2.21; 95% confidence interval [95% CI], 1.52-3.21). Skiers were more likely to use helmets compared to snowboarders (odds ratios, 1.60; 95% CI, 1.16-2.19). Snowboarders had a greater likelihood of concussion (estimated-ß, 2.1; 95% CI, 1.48-2.85) after adjusting for helmet status and age. There was no significant difference in the frequency of concussion among helmeted compared to unhelmeted subjects. Imputing missing values for helmets status had no effect on outcome for concussion. We found no difference in injury severity among helmeted compared to unhelmeted subjects. CONCLUSIONS: Among youth skiers and snowboarders who present to trauma centers with a head injury, the likelihood of that injury involving a concussion was not associated with helmet use.

Whether intestinal barrier disruption precedes or is the consequence of intestinal injury in necrotizing enterocolitis (NEC) remains unknown. Using a neonatal mouse NEC model, we examined the changes in intestinal permeability and specific tight-junction (TJ) proteins preceding NEC and asked whether these changes are prevented by administration of Bifidobacterium infantis, a probiotic known to decrease NEC incidence in humans. Compared with dam-fed controls, pups submitted to the NEC protocol developed i) significantly increased intestinal permeability at 12 and 24 hours (as assessed by 70-kDa fluorescein isothiocyanate-dextran transmucosal flux); ii) occludin and claudin 4 internalization at 12 hours (as assessed by immunofluorescence and low-density membrane fraction immunoblotting); iii) increased claudin 2 expression at 6 hours and decreased claudin 4 and 7 expression at 24 hours; and iv) increased claudin 2 protein at 48 hours. Similar results were seen in human NEC, with claudin 2 protein increased. In mice, administration of B. infantis micro-organisms attenuated increases in intestinal permeability, preserved claudin 4 and occludin localization at TJs, and decreased NEC incidence. Thus, an increase in intestinal permeability precedes NEC and is associated with internalization of claudin 4 and occludin. Administration of B. infantis prevents these changes and reduces NEC incidence. The beneficial effect of B. infantis is, at least in part, due to its TJ and barrier-preserving properties.

The cost associated with type 1 diabetes care is considerable and the rising price of insulin has further amplified this financial burden. To curb insulin costs, numerous policies have been enacted in the past five years, both by pharmaceutical companies and their intermediaries, as well as federal and state legislatures. The most notable example is implementation of insulin cost-sharing cap laws, which place limits on out-of-pocket expenses for insulin, and in some cases, diabetes technology. Although insulin cost-sharing cap laws have the potential to mitigate the financial burden associated with routine diabetes care, these policies have largely benefitted adults living with type 1 diabetes, while children, especially those from racial and ethnic underrepresented groups, appear to have derived limited advantage. We describe the current state of insulin cost-sharing cap laws and utilization among children and adolescents with type 1 diabetes, with a focus on the limitations of current insulin laws, the importance of measuring health outcomes for children who utilize such programs, and the impact on health equity. We provide a call to action for policymakers and provide recommendations for future research in this area.
