Introduction: Hundreds of children suffer burn injuries each day, yet care guidelines regarding the need for acute inpatient treatment vs outpatient follow-up vs no required follow-up remain nebulous. This gap in the literature is particularly salient for the emergency clinician, who must be able to rapidly determine appropriate disposition., Methods: This was a retrospective review of patients presenting to a Level II pediatric trauma center, January 1, 2017-December 31, 2019, and discharged with an International Classification of Diseases, Rev 10, burn diagnosis. We obtained and analyzed demographics, burn characteristics, and follow-up data using univariate and bivariate analysis as well as logistic regression modeling. Patients were stratified into three outcome groups: group 1-patients who underwent emergent evaluation at a burn center or were admitted at their first follow-up appointment; group 2-patients who followed up at a burn center (as an outpatient) or at the emergency department (and were discharged home); and group 3-patients with no known follow-up., Results: A total of 572 patients were included in this study; 58.9% of patients were 1-5 years of age. Sixty-five patients met group 1 criteria, 189 patients met group 2 criteria, and 318 patients met group 3 criteria. Sixty-five percent of patients met at least one American Burn Association criteria, and 79% of all burns were second-degree burns. Flame and scald burns were associated with increased odds (odds ratio [OR] 1.21, OR 1.12) of group 1 vs group 2 + group 3 ( P  = 0.02, P  < 0.001). Second/third-degree burns and concern for non-accidental trauma were also associated with increased odds of group 1 vs 2 or 3 (OR = 1.11, 1.35, P  ≤ 0.001, 0.001, respectively). Scald burns were associated with increased odds of group 2 compared to group 3 (OR 1.11, P  = 0.04). Second/third degree burns were also associated with increased odds of group 2 vs 3 (OR 1.19, P  ≤ 0.001)., Conclusion: There were few statistically significant variables strongly associated with group 1 (emergent treatment/admission) vs group 2 (follow-up/outpatient treatment) vs group 3 (no follow- up). However, one notable finding in this study was the association of scald burns with treatment (admission or follow-up) suggesting that the presence of a scald burn in a child may signify to clinicians that a burn center consult is warranted., Competing Interests: Conflicts of Interest: By the WestJEM article submission agreement, all authors are required to disclose all affiliations, funding sources and financial or management relationships that could be perceived as potential sources of bias.

Introduction: Traumatic brain injury (TBI) causes significant morbidity and mortality in pediatric patients and care is highly variable. Standardized mortality ratio (SMR) summarizes the mortality rate of a specific center relative to the expected rates across all centers, adjusted for case-mix. This study aimed to evaluate variations in SMRs among pediatric trauma centers for TBI., Methods: Patients aged 1-18 diagnosed with TBI within the National Trauma Data Bank (NTDB) from 2017 to 2019 were included. Center-specific SMRs and 95% confidence intervals identified centers with mortality rates significantly better or worse than the median SMR for all centers., Results: 316 centers with 10,598 patients were included. SMRs were risk-adjusted for patient risk factors. Unadjusted mortality ranged from 16.5 to 29.5%. Three centers (1.5%) had significantly better SMR (SMR <1) and three centers (1.5%) had significantly worse SMR (SMR >1). Significantly better centers had a lower proportion of neurosurgical intervention (2.4% vs. 11.8%, p < 0.001), a higher proportion of supplemental oxygen administration (93.7% vs. 83.5%, p = 0.004) and venous thromboembolism prophylaxis (53.2% vs. 40.6%, p < 0.001) compared to significantly worse centers., Conclusions: This study identified centers that have significantly higher and lower mortality rates for pediatric TBI patients relative to the overall median rate. These data provide a benchmark for pediatric TBI outcomes and institutional quality improvement., Level of Evidence: Level III., Type of Study: Retrospective Comparative Study., Competing Interests: Conflicts of interest This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors.

Background: Although millions of children sustain concussions each year, a rapid and objective test for concussion has remained elusive. The aim of this study was to investigate quantitative pupillometry in pediatric patients in the acute, postinjury setting., Methods: This was a prospective case-control study of concussed patients presenting to the emergency department within 72 hours of injury. Pupillary measurements were gathered using NeurOptics' PLR 3000; evaluation included a symptom checklist and neurocognitive assessment. Data were analyzed using descriptive statistics and regression models., Results: A total of 126 participants were enrolled. One significant difference in pupillometry between concussed and control participants was found: left minimum pupil diameter in 12- to 18 year-olds (P = 0.02). Models demonstrating odds of a concussion revealed significant associations for time to 75% recovery (T75) of the left pupil in five- to 11-year-olds and average dilation velocity of the left pupil in 12- to 18-year-olds (P = 0.03 and 0.02 respectively). Models predicting symptom improvement showed one significant association: percent change of the right pupil in five-to-11-year-olds (P = 0.02). Models predicting neurocognitive improvement in 12- to 18-year-olds demonstrated significant association in T75 in the left pupil for visual memory, visual motor processing speed, and reaction time (P = 0.002, P = 0.04, P = 0.04)., Conclusions: The limited statistically significant associations found in this study suggest that pupillometry may not be useful in pediatrics in the acute postinjury setting for either the diagnosis of concussion or to stratify risk for prolonged recovery., Competing Interests: Declaration of competing interest None., (Copyright © 2024 Elsevier Inc.

Objective: To evaluate the impact of acupuncture as part of a traditional Chinese medicine (TCM) treatment plan on lactation and maternal well-being in pump-dependent mothers of hospitalized neonates during the first 30 days after delivery. Study Design: This single-center study was conducted in a level IV regional neonatal intensive care unit with access to integrative health services. Sixty-six mothers were prospectively enrolled in two nonparallel groups: (1) Standard lactation support and (2) standard lactation support augmented with acupuncture. Daily pump volumes were documented. Participants completed a quality-of-life (QOL) survey at baseline and neonatal day of life 30. A linear model was constructed, adjusting for increased milk production over time. Results: Acupuncture was associated with increased milk production at all time points: Day 10 ( p  = 0.0002), day 14 ( p  < 0.0001), day 21 ( p  < 0.0001), and day 30 ( p  < 0.0001). Acupuncture was associated with an increase in three of five QOL components: psychological/child's health ( p  = 0.0006), family/friend relationship ( p  = 0.0006), and health/functioning ( p  = 0.02). Conclusion: Mothers receiving acupuncture reported enhanced milk supply and improved QOL. The limited sample size restricts the broad applicability of the results; nonetheless, this study paves the way for further research on the advantages of merging Eastern and Western treatments to enhance human lactation.

Background: Legal intervention trauma (LIT) is defined as injury due to any encounter with law enforcement. This study investigates associations between demographics, violent status, and law enforcement tactics among youth decedents of LIT., Study Design: Decedents of LIT age 26 years or younger were identified using the CDC's National Violent Death Reporting System from 2003 to 2018. Decedents were classified as "violent" if they possessed a weapon, were committing a violent crime, or if law enforcement reported justified use of force. All others were classified as "nonviolent." Law enforcement tactics were stratified into "lethal" (firearm with standard ammunition) or "less lethal" (any other) force. Differences in the racial distribution across these classifications were assessed using chi-square tests of proportions., Results: We identified 1,281 youth decedents of LIT; of which, 92.5% met violent criteria. Black youths were less likely than White youths to possess a weapon (71.6% vs 77.4%, p = 0.02) and were not more likely to be committing a violent crime (63.6% vs 60.4%, p = 0.27). They were, however, more likely than White youths to experience force reported as justified by law enforcement (89.9% vs 82.4%, p = 0.002) and to experience exclusively lethal force not preceded by less-lethal tactics (94.0% vs 88.7%, p = 0.001). Among the subset of 85 cases where law enforcement reported justified use of force despite the decedent not possessing a weapon or committing a violent crime, the precipitating event was more often a traffic stop for Black youths than for White youths (28.5% vs 6.66%, p = 0.02)., Conclusions: These findings indicate a racial disparity among youth decedents of LIT., (Copyright © 2023 by the American College of Surgeons.

Purpose: Electric bicycles (e-bikes) achieve higher speeds than pedal bicycles, but few studies have investigated the impact on injury rates specific to the pediatric population. Utilizing the National Electronic Injury Surveillance System (NEISS), we compared rates of pediatric injury for e-bikes, bicycles, and gas-engine bicycles (mopeds) from 2011 to 2020., Methods: Descriptive and bivariate inferential analyses were performed upon NEISS estimates of e-bike, bicycle, and moped injuries in children aged 2-18 years. Analyses were stratified by patient age and helmet usage. The Mann-Kendall test of trends was used., Results: We identified 3945 e-bike, 23,389 moped, and 2.05 million bicycle injuries. Over time, the incidence of injury increased for e-bikes (Kendall's τ =0.73, p = 0.004), decreased for pedal bicycles (Kendall's τ = - 0.91, p = 0.0003), and did not change for mopeds (Kendall's τ  = 0.06, p = 0.85). Males accounted for 82.5 % of e-bike injuries. The age group most commonly affected by e-bike injury (44.3 %) was 10-13 years old. The proportion of injuries requiring hospitalization was significantly higher for e-bikes (11.5 %), compared to moped and bicycle (7.0 and 4.8 %, respectively, p < 0.0001). In cases where helmet use or absence was reported, 97.3 % of e-bike riders were without a helmet at the time of injury, compared to 82.1 % of pedal bicycle riders and 87.2 % of moped riders., Conclusions: The rate of pediatric e-bike injuries increased over the study period. Compared to riders on pedal bicycles or mopeds, children on e-bikes had infrequent helmet use and increased rate of hospitalization. These findings suggest that attention to e-bike safety and increasing helmet usage are important to public health among the pediatric population., Level of Evidence: IV., Competing Interests: The authors have no competing interests to declare., (© 2023 The Authors.)

Background: Child maltreatment is distressingly prevalent yet remains under-recognized by healthcare providers. In 2015 the Ohio Children's Hospital Association developed the Timely Recognition of Abusive INjuries (TRAIN) collaborative in an effort to promote child physical abuse (CPA) screening. Our institution implemented the TRAIN initiative in 2019. The objective of this study was to examine the effects of the TRAIN initiative at this institution., Methods: In this retrospective chart review we recorded the incidence of sentinel injuries (SIS) in children presenting to the Emergency Department (ED) of an independent level 2 pediatric trauma center. SIS were defined and identified by a diagnosis of ecchymosis, contusion, fracture, head injury, intracranial hemorrhage, abdominal trauma, open wound, laceration, abrasion, oropharyngeal injury, genital injury, intoxication, or burn in a child < 6.01 months of age. Patients were stratified into pre-TRAIN (PRE), 1/2017-9/2018, or post-TRAIN (POST), 10/2019-7/2020, periods. Repeat injury was defined as a subsequent visit for any of the previously mentioned diagnoses within 12 months of the initial visit. Demographics/visit characteristics were analyzed using Chi square analysis, Fischer's exact test, and student's paired t-test., Results: In the PRE period, 12,812 ED visits were made by children < 6.01 months old; 2.8% of these visits were made by patients with SIS. In the POST period there were 5,372 ED visits, 2.6% involved SIS (p = .4). The rate of skeletal surveys performed on patients with SIS increased from 17.1% in the PRE period to 27.2% in the POST period (p = .01). The positivity rate of skeletal surveys in the PRE versus POST period was 18.9% and 26.3% respectively (p = .45). Repeat injury rates did not differ significantly in patients with SIS pre- versus post-TRAIN (p = .44)., Conclusion: Implementation of TRAIN at this institution appears to be associated with increased skeletal survey rates., (© 2023.

Introduction: VACTERL is defined as 3 or more of the following congenital defects: vertebral, anorectal, cardiac, tracheoesophageal (TE), renal, and limb. The purpose of this study was to create an easy-to-use assessment tool to help providers counsel expecting families regarding the likelihood of additional anomalies and postnatal outcomes., Methods: Employing the Kids' Inpatient Database from 2003-2016, neonates (&lt;29 days old) with VACTERL were identified using ICD-9-CM and ICD-10-CM codes. For each unique combination of VACTERL, multivariable logistic regression was used to estimate inpatient mortality, and Poisson regression was used to estimate length-of-stay during the initial hospitalization., Results: The assessment tool used in this study is available at https://choc-trauma.shinyapps.io/VACTERL. 1,886 of 11,813,782 (0.016%) neonates presented with VACTERL. 32% weighed &lt;1,750 g, and 239 (12.7%) died prior to discharge. Associated with mortality were limb anomaly (1.8 [1.01-3.22], p &lt; 0.05), prematurity (1.99 [1.14-3.47], p &lt; 0.02), and weight &lt;1,750 g (2.19 [1.25-3.82], p &lt; 0.01). Median length-of-stay was 14 days (IQR: 7-32). Associated with increased length-of-stay were cardiac defect (1.47 [1.37-1.56], p &lt; 0.001), vertebral anomaly (1.1 [1.05-1.14], p &lt; 0.001), TE fistula (1.73 [1.66-1.81], p &lt; 0.001), anorectal malformation (1.12 [1.07-1.16], p &lt; 0.001), and weight &lt;1,750 g (1.65 [1.57-1.73], p &lt; 0.001)., Conclusion: This novel assessment tool may help providers counsel families confronting a VACTERL diagnosis., (© 2023 S.

Objective: The aim of this study was to explore the impact of classical music virtual reality (VR) on burnout, secondary traumatic stress, anxiety, and capacity for developing caring relationships with patients among healthcare workers (HCWs)., Background: COVID-19 accentuated the importance of promoting the well-being of frontline workers. Efforts to address the mental health needs of HCWs are likely to positively impact patient outcomes., Methods: Healthcare workers completed 3 sessions of VR. A Wilcoxon rank-sum test was used to compare premeasure versus postmeasure on the Professional Quality of Life (ProQOL), State Trait Anxiety Inventory, and Caring Ability Inventory. Analysis of variance was performed to identify associations between the intervention and differences in scores for each ProQOL domain. Bonferroni correction adjusted for multiple comparisons. Fisher's t test was used for categorical analysis., Results: Seventy-one HCWs completed the study. There was a significant reduction in burnout after the experience, compared with baseline., Conclusions: This study provides evidence that classical music VR may reduce burnout in HCWs., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2022 Wolters Kluwer Health, Inc.

Purpose: To describe the distribution of injuries attributed to inflatable bounce house devices in children 2-18 years old in the United States from 2000 to 2019., Methods: The National Electronic Injury Surveillance System (NEISS) was used to identify patients <18 years of age with injuries from activities classified as amusements (NEISS Code 1293 and 3219) during the period from 2000 to 2019., Results: A weighted estimate of 159,569 injuries was obtained using NEISS statistical weights. Injury estimates and rate of estimated injury per year showed a continued linear increase from 2000-2019 (p<0.0001). Bounce house-related injuries were more common in males (53.9%) than in females (46.1%). The injuries reported most commonly were fracture (25.8%), muscle strain (25.7%), and contusion (14.5%). The factors associated with bounce house-related injury were compared between "younger" patients ≤6 years of age and "older" patients >6 years of age. In both age groups, the patient's residence was the most prevalent location of injury (≤6 yr, 95.6%; >6 yr, 97.2%), and the lower extremity was the most prevalent anatomic site of injury (≤6 yr, 34.6%, >6 yr 35.3%). Concussion was rare in both groups (≤6 yr, 1.6%; >6 yr, 2.9%); however, concussion was 86% more prevalent in those >6 years of age (p<0.0001)., Conclusions: The frequency and rate of pediatric bounce house injuries has increased steadily since 2000. The most severe injuries occur disproportionately in children > 6 years old., (Copyright © 2022. Published by Elsevier Inc.)

Background: Blunt cerebrovascular injury (BCVI) is a rare finding in trauma patients. The previously validated BCVI (Denver and Memphis) prediction model in adult patients was shown to be inadequate as a screening option in injured children. We sought to improve the detection of BCVI by developing a prediction model specific to the pediatric population., Methods: The National Trauma Databank (NTDB) was queried from 2007 to 2015. Test and training datasets of the total number of patients (885,100) with complete ICD data were used to build a random forest model predicting BCVI. All ICD features not used to define BCVI (2268) were included within the random forest model, a machine learning method. A random forest model of 1000 decision trees trying 7 variables at each node was applied to training data (50% of the dataset, 442,600 patients) and validated with test data in the remaining 50% of the dataset. In addition, Denver and Memphis model variables were re-validated and compared to our new model., Results: A total of 885,100 pediatric patients were identified in the NTDB to have experienced blunt pediatric trauma, with 1,998 (0.2%) having a diagnosis of BCVI. Skull fractures (OR 1.004, 95% CI 1.003-1.004), extremity fractures (OR 1.001, 95% 1.0006-1.002), and vertebral injuries (OR 1.004, 95% CI 1.003-1.004) were associated with increased risk for BCVI. The BCVI prediction model identified 94.4% of BCVI patients and 76.1% of non-BCVI patients within the NTDB. This study identified ICD9/ICD10 codes with strong association to BCVI. The Denver and Memphis criteria were re-applied to NTDB data to compare validity and only correctly identified 13.4% of total BCVI patients and 99.1% of non BCVI patients., Conclusion: The prediction model developed in this study is able to better identify pediatric patients who should be screened with further imaging to identify BCVI., Level of Evidence: Retrospective diagnostic study-level III evidence., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2021.

Background: Previous studies have assessed the prevalence and nature of traumatic injuries due to legal intervention in adults. The purpose of this study is to characterize and understand legal intervention trauma in children., Methods: The National Trauma Data Bank (NTDB) was queried from 2007 to 2015. Patients (0-18 years old) who sustained injuries due to legal intervention were compared to those injured from other causes in the general NTDB population. Descriptive statistics were used to characterize the study population. Multivariate logistic regression models were utilized to predict firearm trauma and mortality., Results: 622 patients sustained injuries involving legal intervention. Compared to general NTDB pediatric population, those who sustained legal intervention injuries were more likely to be older (age 16.5 vs. 10.6, p < 0.01), male (91.96% vs. 34.95%, p < 0.01), test positive for illegal drugs (64.64% vs. 38.35%, p < 0.01) or alcohol (26.36% vs. 17.25%, p < 0.01), and be African-American (44.37% vs. 17.00%, p < 0.01), Latino (22.82% vs. 15.10%, p < 0.01), or Native American (0.96% vs.. 0.94%, p < 0.01). Logistic regression models identified an 11% increased odds (95% CI 1.02-1.21, p = 0.02) of death among African-Americans when compared to other racial groups receiving legal intervention trauma. African-American status was associated with a 12% increased odds (95% CI 1.02-1.22, p = 0.01) of firearm trauma when compared to other racial groups receiving legal intervention trauma., Conclusion: Legal intervention-related pediatric trauma disproportionately affects the African-American population. This is particularly pronounced in cases of firearm related injuries., Level of Evidence: III., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2021 Elsevier Inc.

Background: The durability of the immune response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination remains unknown. The objective of this study was to evaluate a rapid SARS-CoV-2 IgM/IgG antibody detection kit as a qualitative screen for the humoral response to vaccination., Methods: Study participants (n = 125) included pediatric healthcare workers (HCWs) who had received two doses of BNT162b2 or mRNA-1273. Participants were tested on study entry (March 12, 2021 to April 9, 2021). The mean number of days post second dose was 22 (range 17-36). Participants were tested for IgM/IgG antibodies to the SARS-CoV-2 spike protein with the RightSign COVID-19 IgG/IgM Rapid Test Cassette. ELISA/competitive inhibition ELISA (CI-ELISA) were subsequently run to assess for the neutralization effect and SARS-CoV-2 anti-nucleocapsid IgM/IgG antibodies., Results: Overall, 98.4% of participants were IgG-positive and 0.8% were IgM-positive on rapid RightSign testing. Of those with IgG-positive results, 100% were anti-spike protein IgG-positive on CI-ELISA; none of those who tested IgG-negative via the rapid test were IgG-positive on CI-ELISA. All HCWs who tested RightSign positive demonstrated neutralizing capability on CI-ELISA. Overall, 1.6% demonstrated anti-nucleocapsid IgM antibodies and 5.6% demonstrated anti-nucleocapsid IgG antibodies., Conclusions: The strong agreement between the rapid RightSign IgG results and confirmatory CI-ELISA testing suggests that this test may be used to assess for positive, and neutralizing, antibody responses to SARS-CoV-2 mRNA vaccination., (Copyright © 2021 The Author(s).

Background: Health care workers face occupational stressors that may lead to burnout and secondary traumatic stress. Strategies to mitigate the negative psychological impact on frontline workers are urgently needed., Objective: The purpose of this study was to evaluate the effect of auricular acupuncture or acupressure, as compared with ear massage, on anxiety, burnout, and caring capacity in health care workers. Results were stratified on the basis of subject's level of belief in traditional Chinese medicine., Methods: This prospective randomized trial with an open, parallel-group design was conducted at a 334-bed Level II pediatric trauma center. Participants were randomized to one of three groups: (1) auricular acupuncture, (2) auricular seed acupressure, or (3) auricular massage. Interventions were delivered over 3 weeks. Self-reported State-Trait Anxiety Inventory (STAI), Professional Quality of Life (ProQOL), and Caring Ability Inventory (CAI) scores were analyzed using a pre-/posttest design. Univariate analysis, Fisher's exact test, and analysis of variance (ANOVA) were performed to assess group differences., Results: A total of 117 (36%) of 325 eligible participants consented to participate in the study. Seed acupressure treatment (n = 14, 35.9%, one male, 13 females) was associated with a reduction in burnout (ANOVA, p = .04) and secondary traumatic stress (p = .03). This effect remained significant after adjusting for individual pretest scores (ANOVA, p = .05). The studied interventions did not have a significant effect on STAI, ProQOL, or CAI scores., Conclusions: Auricular acupressure is a safe, effective, and practical strategy to reduce burnout and secondary traumatic stress and may support health care workers' ability to develop caring relationships with patients and families., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2021 Society of Trauma Nurses.)

Background: Neck-related chief complaints are common in the pediatric Emergency Department (ED), and although the incidence of pathology such as retropharyngeal abscesses is rare, the ability to rule out abscesses requiring surgical/procedural intervention is essential. However, there are no clear clinical guidelines regarding work-up and diagnosis in this population, possibly contributing to an excess use of potentially harmful and costly computed tomography (CT) imaging., Objective: In this study we sought to identify historical, physical exam, and laboratory findings associated with surgically significant neck abscesses to better delineate CT neck imaging criteria., Methods: We conducted a retrospective chart review of all patients ≤18 years presenting to a pediatric ED between 2013 and 2017 who underwent CT neck imaging. Surgically significant abscesses (SSAs) were defined as abscesses ≥2 cm, retropharyngeal abscesses (RPA), parapharyngeal abscesses (PPA), or peritonsillar abscesses (PTA). Historical factors, physical exam findings, laboratory results, demographics, and CT results were analyzed using univariate statistical analysis and regression models., Results: A total of 718 patients received neck CTs and 153 SSAs were identified. In children younger than 6 years, factors associated with statistically significant increased odds of an SSA were reported throat pain (OR 1.18; 95% CI 1.05, 1.33), fussiness (OR 1.18; 1.01, 1.39), lethargy (OR 1.43; 1.07, 1.91), tonsillar enlargement (OR 1.17; 1.02, 1.34), C-reactive protein (CRP) > 10 (OR 1.22; 1.07, 1.40), and an ED visit within the preceding week (OR 1.18; 1.04, 1.33). In children older than 6 years, the factors associated with statistically significant increased odds of an SSA included current antibiotic use (OR 1.12; 1.02, 1.22) and a CRP >10 (OR 1.14; 1.03, 1.26)., Conclusion: Some historical, physical exam, and laboratory findings are associated with SSAs, and while not definitive in isolation, may be beneficial additions to routine SSA assessment, as a supplement to clinical judgement regarding CT and observation decisions. This may potentially allow for the identification of patients requiring CT versus those who may not, and thus the opportunity to safely reduce the use of CT imaging in select patients., (Copyright © 2021 Elsevier B.V.

Introduction: Unintentional falls are a leading cause of pediatric traumatic injury. This study evaluates clinical outcomes of fall-related injuries in children under the age of 10., Methods: The National Trauma Database was queried for children who experienced an unintentional fall. Patients were stratified by age in two groups: 1-5 and 6-10 years old. The primary outcome was post discharge extension of care, defined as transfer to skilled nursing facility or rehabilitation center after discharge from the hospital. Descriptive statistics and a multivariable logistic regression analysis were used to compare the two groups., Results: From 2009 to 2016, a total of 8,277 pediatric patients experienced an unintentional fall, with 93.6% of patients being discharged home. Falls were more common in younger children, with greater odds of post discharge extension of care. Predictors of increased associated risk of extended medical care included intracranial hemorrhage (OR 1.05, 95% CI 1.03-1.06) and thoracic injuries (OR 1.03, 95% CI 1.00-1.1.05) (P< 0.05). Mortality in pediatric patients suffering unintentional falls was a rare event occurring in 0.7% of cases in children 1-5 years old and 0.4% of children 6-10 years old., Conclusion: The majority of children experiencing an unintentional fall are discharged home, with mortality being very rare. However, younger age is prone to more severe and serious injury patterns. Intracranial hemorrhage and thoracic injury were a predictor of need for extended medical care., (Copyright © 2021.

Introduction: Dog bites are a significant health concern in the pediatric population. Few studies published to date have stratified the injuries caused by dog bites based on surgical severity to elucidate the contributing risk factors., Methods: We used an electronic hospital database to identify all patients ≤17 years of age treated for dog bites from 2013-2018. Data related to patient demographics, injury type, intervention, dog breed, and payer source were collected. We extracted socioeconomic data from the American Community Survey. Data related to dog breed was obtained from public records on dog licenses. We calculated descriptive statistics as well as relative risk of dog bite by breed., Results: Of 1,252 injuries identified in 967 pediatric patients, 17.1% required consultation with a surgical specialist for repair. Bites affecting the head/neck region were most common (61.7%) and most likely to require operating room intervention (P = 0.002). The relative risk of a patient being bitten in a low-income area was 2.24, compared with 0.46 in a high-income area. Among cases where the breed of dog responsible for the bite was known, the dog breed most commonly associated with severe bites was the pit bull (relative risk vs German shepherd 8.53, relative risk vs unknown, 3.28)., Conclusion: The majority of injuries did not require repair and were sufficiently handled by an emergency physician. Repair by a surgical specialist was required <20% of the time, usually for bites affecting the head/neck region. Disparities in the frequency and characteristics of dog bites across socioeconomic levels and dog breeds suggest that public education efforts may decrease the incidence of pediatric dog bites.

Background: Apheresis procedures require adequate vascular access to achieve optimal inlet flow rates. While central lines provide such access, their placement and use are associated with risks; some of these risks are minimized if peripheral intravenous access can be established. However, peripheral intravenous access is associated with challenges in the pediatric setting. Research indicates that midline catheters reduce the use of CVADs and their associated risks. The use of midline catheters for apheresis has been reported recently in adults, but no studies have been published on their use in children. Thus, the purpose of this study was to evaluate the use of midline catheters for apheresis in the pediatric setting., Methods: A retrospective observational study was conducted to evaluate the safety and efficacy of midline catheters in subjects who underwent apheresis at a pediatric hospital from April 2018 to August 2020. Demographic data, clinical data (diagnosis, procedure, catheter size, body mass), and outcome data (inlet flow rate, total blood volume [TBV] processed, procedure time, and cell counts) were collected., Results: Eighteen subjects received a total of 100 midline catheters for 73 apheresis procedures. Inlet flow rates ranged from 45 to 80 mL/min, TBV ranged from 2872 to 20 000 mL, and procedure time ranged from 1.25 to 7 hours. Inlet flow rates met or exceeded the recommended inlet flow rates for apheresis in children and adults (P < .0001). No adverse events occurred., Conclusion: Midline catheters provide safe and effective vascular access for apheresis. Future research should include younger patients with lower body mass., (© 2021 Wiley Periodicals LLC.)

Background: In this study, trauma-specific risk factors of prolonged length of stay (LOS) in pediatric trauma were examined. Statistical and machine learning models were used to proffer ways to improve the quality of care of patients at risk of prolonged length of stay and reduce cost., Methods: Data from 27 hospitals were retrieved on 81,929 hospitalizations of pediatric patients with a primary diagnosis of trauma, and for which the LOS was >24 h. Nested mixed effects model was used for simplified statistical inference, while a stochastic gradient boosting model, considering high-order statistical interactions, was built for prediction., Results: Over 18.7% of the encounters had LOS >1 week. Burns and corrosion and suspected and confirmed child abuse are the strongest drivers of prolonged LOS. Several other trauma-specific and general pediatric clinical variables were also predictors of prolonged LOS. The stochastic gradient model obtained an area under the receiver operator characteristic curve of 0.912 (0.907, 0.917)., Conclusions: The high performance of the machine learning model coupled with statistical inference from the mixed effects model provide an opportunity for targeted interventions to improve quality of care of trauma patients likely to require long length of stay., Impact: Targeted interventions on high-risk patients would improve the quality of care of pediatric trauma patients and reduce the length of stay. This comprehensive study includes data from multiple hospitals analyzed with advanced statistical and machine learning models. The statistical and machine learning models provide opportunities for targeted interventions and reduction in prolonged length of stay reducing the burden of hospitalization on families., (© 2020.

Background: Neonates receiving extracorporeal life support (ECLS) for congenital diaphragmatic hernia (CDH) require prolonged support compared with neonates with other forms of respiratory failure. Hemolysis is a complication that can be seen during ECLS and can lead to renal failure and potentially to worse outcomes. The purpose of this study was to identify risk factors for the development of hemolysis in CDH patients treated with ECLS., Methods: The Extracorporeal Life Support Organization database was used to identify infants with CDH (2000-2015). The primary outcome was hemolysis (plasma-free hemoglobin >50 mg/dL). Potentially associated variables were identified in the data set. Descriptive statistics and a series of nested multivariable logistic regression models were used to identify associations between hemolysis and demographic, pre-ECLS, and on-ECLS factors., Results: There were 4576 infants with a mortality of 52.5%. The overall mean rate of hemolysis was 10.5% during the study period. In earlier years (2000-2005), the hemolysis rates were 6.3% and 52.7% for roller versus centrifugal pumps, whereas in later years (2010-2015), they were 2.9% and 26.5%, respectively. The fully adjusted model demonstrated that the use of centrifugal pumps was a strong predictor of hemolysis (odds ratio: 6.67, 95% confidence interval: 5.14-8.67). In addition, other risk factors for hemolysis included low 5-min Apgar score, on-ECLS complications (renal, metabolic, and cardiovascular), and duration of ECLS., Conclusions: In our cohort of CDH patients receiving ECLS over 15 y, the use of centrifugal pumps increased over time, along with the rate of hemolysis. Patient- and treatment-level risk factors were identified contributing to the development of hemolysis., (Copyright © 2021 Elsevier Inc. All rights reserved.)

Background and Objectives: There is widespread concern that the COVID-19 pandemic has increased the incidence of child maltreatment. However, reports in the scientific literature documenting rates of child maltreatment during this period are scarce. This study was designed to explore whether the incidence of child maltreatment among patients presenting to a pediatric emergency department has increased during the COVID-19 pandemic., Methods: We conducted a retrospective review of patients of all ages presenting to a pediatric Emergency Department trauma center, who also had a child abuse report filing or a sentinel injury diagnosis related to their index visit. All such patients who presented to this institution from March through July of 2017 through 2020 were included in the study., Results: Analysis demonstrated an increase in the incidence of child maltreatment in May and June of 2020 and that there was an overall shift in distribution of types of child maltreatment during the COVID-19 pandemic. There was a significant increase in the proportion of emotional/psychological abuse (2.52 % before the pandemic to 7.00 % during the pandemic, p ≤ 0.0001) and non-medical neglect (31.5%-40.0%, p ≤ 0.0001)., Conclusions: We observed an increase in specific types of child maltreatment during the COVID-19 pandemic. These findings highlight the need for increased attention to children at risk for child abuse and neglect., (Copyright © 2021 Elsevier Ltd. All rights reserved.)

Purpose: The purpose of this study was to determine if routine chest X-rays (CXRs) performed after chest tube (CT) removal in pediatric patients provide additional benefit for clinical management compared to observation of symptoms alone., Methods: A single-center retrospective study was conducted of inpatients, 18 years or younger, who had a CT managed by the pediatric surgery team between July 2017 and May 2019. The study compared two groups: (1) patients who received a post-pull CXR and (2) those who did not. The primary outcome of the study was the need for intervention after CT removal., Results: 102 patients had 116 CTs and met inclusion criteria; 79 post-pull CXRs were performed; the remaining 37 CT pulls did not have a follow-up CXR. No patients required CT replacement or surgery in the absence of symptoms. Three patients exhibited clinical symptoms that would have prompted intervention regardless of post-pull CXR results. One patient had an intervention guided by post-pull CXR results alone. Meanwhile, another patient had delayed onset of symptoms and intervention. No patients required an intervention in the group that did not have a post-pull CXR., Conclusion: Chest X-ray after CT removal had a very low yield for changing clinical management of asymptomatic patients. Clinical symptoms predict the need for an intervention.

Introduction: Limited data on the seroprevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) among healthcare workers (HCW) are publicly available. In this study we sought to determine the seroprevalence of SARS-CoV-2 in a population of HCWs in a pediatric emergency department (ED)., Methods: We conducted this observational cohort study from April 14-May 13, 2020 in a pediatric ED in Orange County, CA. Asymptomatic HCW ≥18 years of age were included in the study. Blood samples were obtained by fingerstick at the start of each shift. The inter-sampling interval was ≤96 hours. The primary outcome was positive seroprevalence of SARS-CoV-2 as determined with an antibody fast detection kit (Colloidal Gold, Superbio, Timisoara, Romania) for the SARS-CoV-2 immunoglobulin M/immunoglobulin G (IgM/IgG) antibody., Results: A total of 143 HCWs participated in the study. Overall SARS-CoV-2 seroprevalence was 10.5% (n = 15). Positive seroprevalence was classified as IgG only (4.9%), IgM+IgG (3.5%), or IgM only (2.1%). SARS-CoV-2 was detected by reverse transcription polymerase chain reaction RT-PCR in 0.7% of the overall study population (n = 1). Samples obtained on Day 1 indicated seropositivity in 4.2% of the study population (n = 6). Subsequent seroconversion occurred in 6.3% of participants (n = 9). The rate of seroconversion was linear with a rate of approximately one new case every two days, starting at Day 9 of the study., Conclusion: We observed a linear rate of seroconversion to SARS-CoV-2-positive status among asymptomatic HCWs who underwent daily symptom surveys and temperature screens in an environment with universal source control. Rapid antibody testing may be useful for screening for SARS-CoV-2 seropositivity in high-risk populations, such as HCWs in the ED.

Luteolin inhibited growth of several cancer cells in vitro in previous studies, with limited in vivo studies, and no comprehensive understanding of molecular mechanisms at genomics level. This study identified luteolin as an effective agent to inhibit melanoma cell growth in vitro and in vivo. Molecular studies and genomic profiling were used to identify the mechanism of action of luteolin in melanoma cells. As a ROS (reactive oxygen species) scavenger, luteolin unexpectedly induced ROS; but co-treatment with antioxidants NAC or mito-TEMPO did not rescue cell growth inhibition, although the levels of ROS levels were reduced. Next, we profiled luteolin-induced differentially expressed genes (DEGs) in 4 melanoma cell lines using RNA-Seq, and performed pathway analysis using a combination of bioinformatics software including PharmetRx which was especially effective in discovering pharmacological pathways for potential drugs. Our results show that luteolin induces changes in three main aspects: the cell-cell interacting pathway (extracellular matrix, ECM), the oncogenic pathway and the immune response signaling pathway. Based on these results, we further validated that luteolin was especially effective in inhibiting cell proliferation when cells were seeded at low density, concomitantly with down-regulation of fibronectin accumulation. In conclusion, through extensive DEG profiling in a total of 4 melanoma cell lines, we found that luteolin-mediated growth inhibition in melanoma cells was perhaps not through ROS induction, but likely through simultaneously acting on multiple pathways including the ECM (extracellular matrix) pathway, the oncogenic signaling and the immune response pathways. Further investigations on the mechanisms of this promising compound are warranted and likely result in application to cancer patients as its safety pharmacology has been validated in autism patients., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020 Elsevier Inc.

Treatment of head and neck cancer has been slow to change with epidermal growth factor receptor (EGFR) inhibitors, PD1 inhibitors, and taxane-/plant-alkaloid-derived chemotherapies being the only therapies approved by the U.S. Food and Drug Administration (FDA) in the last 10 years for the treatment of head and neck cancers. Head and neck cancer is a relatively rare cancer compared to breast or lung cancers. However, it is possible that existing therapies for more common solid tumors or for the treatment of other diseases could also prove effective against oral cancers. Many therapies have molecular targets that could be appropriate in oral cancer as well as the cancer in which the drug gained initial FDA approval. Also, there may be targets in oral cancer for which existing FDA-approved drugs could be applied. This study describes informatics methods that use machine learning to identify influential gene targets in patients receiving platinum-based chemotherapy, non-platinum-based chemotherapy, and genes influential in both groups of patients. This analysis yielded 6 small molecules that had a high Tanimoto similarity (>50%) to ligands binding genes shown to be highly influential in determining treatment response in oral cancer patients. In addition to influencing treatment response, these genes were also found to act as gene hubs connected to more than 100 other genes in pathways enriched with genes determined to be influential in treatment response by a random forest classifier with 20 000 trees trying 320 variables at each tree node. This analysis validates the use of multiple informatics methods to identify small molecules that have a greater likelihood of efficacy in a given cancer of interest., Competing Interests: Declaration of conflicting interests:The author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: JS is employed in bioinformatics research at Afecta Pharmaceuticals and the platform Pharmetrx.ai which is a branch of Afecta Pharmaceuticals., (© The Author(s) 2019.)

Objectives: This study aims to identify a robust signature that performs well in predicting overall survival across tumor phenotypes and treatment strata, and validates the application of Monte Carlo cross validation (MCCV) as a means of identifying molecular signatures when utilizing small and highly heterogeneous datasets., Materials and Methods: RNA sequence gene expression data for 264 patient tumors were acquired from The Cancer Genome Atlas (TCGA). 100 iterations of Monte Carlo cross validation were applied to differential expression and Cox model validation. The association between the gene signature risk score and overall survival was measured using Kaplan-Meier survival curves, univariate, and multivariable Cox regression analyses., Results: Pathway analysis findings indicate that ligand-gated ion channel pathways are the most significantly enriched with the genes in the aggregated signature. The aggregated signature described in this study is predictive of overall survival in oral cancer patients across demographic and treatment strata., Conclusion: This study reinforces previous findings supporting the role of ion channel gating, interleukin, calcitonin receptor, and keratinization pathways in tumor progression and treatment response in oral cancer. These results strengthen the argument that differential expression of genes within these pathways reduces tumor susceptibility to treatment. Conducting differential gene expression (DGE) with Monte Carlo cross validation, as this study describes, offers a potential solution to decreasing the variability in DGE results across future studies that are reliant upon highly heterogeneous datasets. This improves the ability of studies reliant upon similarly structured datasets to reach results that are reproducible., (Copyright © 2018 Elsevier Ltd. All rights reserved.)

Objective: The management of hyperparathyroidism in hemodialysis patients involves the administration of phosphate binders, vitamin D receptor activators, and calcimimetics. Intravenous paricalcitol has been preferred over oral calcitriol as it may cause less hypercalcemia and hyperphosphatemia. However, there is little data looking at the efficacy and tolerability of oral calcitriol in the calcimimetic era particularly in a real practice-based experience. The University of California, Irvine free-standing dialysis center converted from routine intravenous paricalcitol to oral calcitriol due to pharmacy purchasing preferences. We report the efficacy, safety, and cost of such a change., Subjects: Ninety-three preconversion intravenous paricalcitol and 91 postconversion oral calcitriol., Intervention: Conversion to in-center, pulse, oral calcitriol (0.25 mcg = 1 mcg paricalcitol) 3 times a week from intravenous paricalcitol. Additional dose adjustments were made by the nephrologists based on clinical indications., Main Outcome Measure: Five-month average serum calcium, phosphorous, and intact parathyroid hormone levels and cardiovascular events pretransition and posttransition., Results: There were 93 patients on intravenous paricalcitol between April 2013 and August 2013, of which 74 converted to oral calcitriol and were included in the postconversion group evaluated between October 2013 and February 2014. An additional 17 new patients had initiated calcitriol such that 91 patients were on oral therapy in the postconversion period. Sevelamer use increased from 41 (44.1%) patients preconversion to 48 (52.7%) postconversion, whereas calcium acetate use significantly dropped from 62 (66.7%) to 46 (50.5%) (P = .026). Cinacalcet use dropped slightly from 37 (39.7%) patients preconversion to 35 (38.4%) postconversion. Average serum calcium, phosphorus, and intact parathyroid hormone levels remained unchanged after conversion. Percent of values within Kidney Disease Outcome Quality Initiative guidelines were similarly maintained. Estimated vitamin D cost savings were $564 per person/year. No increase in the incidence of cardiovascular events was observed., Conclusions: We conclude that in-center distributed pulse oral calcitriol may be an effective, safe, and economical treatment option for the management of hyperparathyroidism in hemodialysis patients., (Copyright © 2016 National Kidney Foundation, Inc.

Foodborne illness is prevented by inspection and surveillance conducted by health departments across America. Appropriate restaurant behavior is enforced and monitored via public health inspections. However, surveillance coverage provided by state and local health departments is insufficient in preventing the rising number of foodborne illness outbreaks. To address this need for improved surveillance coverage we conducted a supplementary form of public health surveillance using social media data: Yelp.com restaurant reviews in the city of San Francisco. Yelp is a social media site where users post reviews and rate restaurants they have personally visited. Presence of keywords related to health code regulations and foodborne illness symptoms, number of restaurant reviews, number of Yelp stars, and restaurant price range were included in a model predicting a restaurant's likelihood of health code violation measured by the assigned San Francisco public health code rating. For a list of major health code violations see (S1 Table). We built the predictive model using 71,360 Yelp reviews of restaurants in the San Francisco Bay Area. The predictive model was able to predict health code violations in 78% of the restaurants receiving serious citations in our pilot study of 440 restaurants. Training and validation data sets each pulled data from 220 restaurants in San Francisco. Keyword analysis of free text within Yelp not only improved detection of high-risk restaurants, but it also served to identify specific risk factors related to health code violation. To further validate our model we applied the model generated in our pilot study to Yelp data from 1,542 restaurants in San Francisco. The model achieved 91% sensitivity 74% specificity, area under the receiver operator curve of 98%, and positive predictive value of 29% (given a substandard health code rating prevalence of 10%). When our model was applied to restaurant reviews in New York City we achieved 74% sensitivity, 54% specificity, area under the receiver operator curve of 77%, and positive predictive value of 25% (given a prevalence of 12%). Model accuracy improved when reviews ranked highest by Yelp were utilized. Our results indicate that public health surveillance can be improved by using social media data to identify restaurants at high risk for health code violation. Additionally, using highly ranked Yelp reviews improves predictive power and limits the number of reviews needed to generate prediction. Use of this approach as an adjunct to current risk ranking of restaurants prior to inspection may enhance detection of those restaurants participating in high risk practices that may have gone previously undetected. This model represents a step forward in the integration of social media into meaningful public health interventions.

Sevelamer hydrochloride (HCl), a calcium-free phosphate binder, is increasingly used due to concerns related to calcium exposure and the development of vascular calcifications. However, a common side effect of sevelamer HCl, metabolic acidosis, is particularly concerning in children, as it can contribute to poor growth. Sevelamer carbonate is now available and has been shown to increase serum bicarbonate in adult patients. We conducted a prospective single-center study of pediatric dialysis patients comparing serum bicarbonate before and 3 months after a switch from sevelamer HCl to sevelamer carbonate. Inclusion criteria were a minimum of 3 months of dialysis therapy and either a serum bicarbonate <20 mmol/L or the need for sodium bicarbonate supplementation. Ten hemodialysis and 14 peritoneal dialysis patients, aged 16 +/- 3 years, were enrolled. Whereas serum calcium and phosphorus remained unchanged, serum bicarbonate increased from 20 (17.2-22.0) to 24.5 (20.75-26) mmol/L (p < 0.001) after 3 months of sevelamer carbonate therapy. Sodium bicarbonate supplementation was stopped in all patients (n = 10), reducing the mean daily sodium intake by an average of 2.3 g per patient. These results demonstrate that sevelamer carbonate is an effective phosphate binder that improves acid-base status in pediatric dialysis patients.
