A phase 4, open-label study to evaluate the safety and immunogenicity of DTaP5-HBV-IPV-Hib in children previously vaccinated with DTaP2-HBV-IPV-Hib or DTaP5-HBV-IPV-Hib (V419-016)

DTaP5-HBV-IPV-Hib (Vaxelis®) is a hexavalent combination vaccine (HV) indicated in infants and toddlers for the prevention of diphtheria, tetanus, pertussis, hepatitis B, poliomyelitis, and invasive disease due to Haemophilus influenzae type b. Switching between HVs during the childhood vaccination series is sometimes necessary due to, for example, vaccine availability, health-care provider preference, and/or tender awards. The purpose of this study was to describe the safety, tolerability, and immunogenicity of a booster dose of Vaxelis® in participants who previously received a primary infant series of either DTaP2-HBV-IPV-Hib (Hexyon®) or Vaxelis®. Healthy participants approximately 11-13 months of age who previously received a two-dose primary series of Hexyon® (HHV group) or Vaxelis® (VVV group) all received a Vaxelis® booster dose. Immunogenicity was evaluated by measuring antibody levels to individual vaccine antigens approximately 30 days following booster vaccination. Safety was evaluated as the proportion of participants with adverse events (AEs). The proportions of participants with antibody-specific responses for antigens contained in both Vaxelis® and Hexyon® at 30 days post-toddler-booster vaccination with Vaxelis® were comparable between groups, and higher in the VVV group for Vaxelis® antigens PRN and FIM2/3. The overall proportions of participants with AEs were generally comparable between groups. Following a booster dose of Vaxelis®, immune responses were comparable between groups for all shared antigens, and higher in the VVV group for antigens found only in Vaxelis®. The booster was well tolerated in both groups. These data support the use of Vaxelis® as a booster in mixed HV regimens.

Detailed immune profiling in pediatric Crohn's disease using methylation cytometry

DNA methylation has been extensively utilized to study epigenetic patterns across many diseases as well as to deconvolve blood cell type proportions. This study builds upon previous studies examining methylation patterns in paediatric patients with varying stages of Crohn's disease to extend the immune profiling of these patients using a novel deconvolution approach. Compared with control subjects, we observed significantly decreased levels of CD4 memory and naive, CD8 naive, and natural killer cells and elevated neutrophil levels in Crohn's disease. In addition, Crohn's patients had a significantly elevated neutrophil-to-lymphocyte ratio. Using an epigenome-wide association approach and adjusting for potential confounders, including cell type, we observed 397 differentially methylated CpG (DMC) sites associated with Crohn's disease. The top genetic pathway associated with the DMCs was the regulation of arginine metabolic processes which are involved in the regulation of T cells.

The value of bioimpedance analysis in the assessment of hydration and nutritional status in children on chronic peritoneal dialysis

Bioimpedance analysis (BIA)-body composition monitoring (BCM) has been used to evaluate the hydration and nutritional status of adults and children on dialysis. However, its clinical application still has challenges, so further exploration is valuable. We used BIA-BCM to evaluate the hydration and nutritional status of children undergoing chronic peritoneal dialysis from 1 July 2021 to 31 December 2022 in the Children's Hospital of Fudan University to explore the clinical value of this method. A total of 84 children on chronic peritoneal dialysis (PD) were included. In the PD group, 16 (19.05%) and 31 (36.90%) had mild and severe overhydration (OH), respectively; 41.27% (26/63) had a low lean tissue index (LTI). In the PD group, patients with relative OH (Re-OH) > 5.6% had significantly higher systolic blood pressure (SBP) and SBP z score (SBPz). Patients with LTI > 12% had significantly higher body mass index (BMI) and BMI z score (BMIz). Canonical correlation analysis indicated a linear relationship (ρ = 0.708) between BIA-BCM hydration and the clinical hydration indicator and a linear relationship (ρ = 0.995) between the BIA-BCM nutritional indicator and the clinical nutritional indicator. A total of 56% of children on chronic peritoneal dialysis had OH, and 41% had a low LTI. In PD patients, SBP and SBPz were correlated with BIA-BCM Re-OH, and BMI and BMIz were correlated with BIA-BCM LTI. BIA-BCM indicators have good clinical value in evaluating hydration and nutrition.

Bernard-Soulier syndrome caused by two novel heterozygous GP1BA gene mutations: a case report and literature review

BACKGROUND

Bernard-Soulier syndrome (BSS) is a rare inherited macrothrombocytopenia, usually autosomal recessive, which is characterized by prolonged bleeding, thrombocytopenia, and abnormally large platelets.

METHODS

For more than 6 years, we misdiagnosed a patient with BSS without an obvious bleeding tendency as having idiopathic thrombocytopenia purpura (ITP), prior to obtaining a genetic analysis. On admission, routine hematology showed a platelet count of 30 × 109/L and mean platelet volume (MPV) of 14.0 fL.

RESULTS

Whole-exome sequencing revealed two likely pathogenic heterozygous mutations (c.95_101del and c.1012del) in GP1BA. Flow cytometry analysis of platelet membrane glycoproteins indicated that the expression of GP1b was 0.28% of the normal level. Platelet aggregation tests indicated that platelet aggregation was inhibited by ristocetin- (1.7%), ADP- (14.5%), and arachidonic acid- (5.6%) induced platelet aggregation. A literature review identified reports on 53 mutations in the GP1BA gene in 253 patients, 29 mutations in the GP1BB gene in 90 patients, and 32 mutations in the GP9 gene in 114 patients.

CONCLUSION

This case report describes two novel gene mutation sites that have not been reported previously, enriching understanding of the GP1BA mutation spectrum.

Efficacy and safety of 308-nm Excimer lamp combined with Tacrolimus 0.1% ointment vs Tacrolimus 0.1% ointment as monotherapy in treating children with limited vitiligo: a randomized controlled trial

OBJECTIVE

This study aims to assess the efficacy and safety of combining the 308-nm Excimer lamp with Tacrolimus 0.1% ointment, compared to Tacrolimus 0.1% ointment monotherapy, for treating pediatric vitiligo involving less than 10% of the body surface area.

METHODS

Fifty pediatric patients with vitiligo were randomly assigned to two groups. Group A received Tacrolimus 0.1% ointment twice daily and Excimer light at 308-nm twice weekly, while Group B received Tacrolimus 0.1% ointment alone, administered twice daily. Repigmentation percentages were evaluated after 30, 90, and 180 days using the rule of nine.

RESULTS

Group A exhibited a significant improvement in repigmentation, increasing from 10% after one month to 65% after six months. In contrast, Group B observed an increase from 10% to 30% over the same timeframe. The efficacy of the treatment was significantly higher in Group A at both the 3-month and 6-month follow-up points (p-value < .001). Moreover, Group A achieved notably higher repigmentation rates in the face, trunk, and lower limbs.

CONCLUSION

The combination of Tacrolimus and the 308-nm excimer lamp yielded superior repigmentation results compared to Tacrolimus monotherapy in pediatric vitiligo patients. This combined approach may offer an effective new treatment protocol for pediatric vitiligo.

Pediatric splenic infarction: Assessment of associated clinical conditions and outcome

Pediatric splenic infarction (SI) is rare yet clinically significant. Publications regarding this complication are mostly limited to case reports. This is a retrospective study examining SI etiology, clinical presentation, management, and outcomes among children. Twenty-two patients (median age: 7.9 years) were included, mostly with pre-existing hematological diseases. Splenomegaly (72%), thrombocytopenia, and anemia were common. Most of the patients did not receive antithrombotic therapy yet only two patients experienced recurrences. During follow up 36% of patients died, however no fatalities were attributed to thrombotic or bleeding complications.

Demographic and Clinical Predictors of Pharmacist-Administered Pediatric Influenza Immunization

Background: Pediatricians' offices are primary locations for pediatric influenza vaccination; however, pharmacists are also well-positioned as immunizers. Considering the current COVID-19 pandemic and Public Readiness and Emergency Preparedness (PREP) Act, pharmacists' authority to vaccinate children has been recently expanded. Methods: We used the de-identified Optum ClinformaticsTM Data Mart database to identify demographic and clinical predictors of pharmacist-administered pediatric influenza vaccination compared with influenza vaccination in pediatricians' offices. Procedures codes for influenza vaccinations among children were captured for the 2016-2017 influenza season. Logistic regression was used to identify significant predictors. Results: We included 336 841 children receiving influenza vaccines by a pharmacist (5.2%) or in pediatricians' offices (94.8%). The following significant predictors were identified: older pediatric age groups (13-17 years odds ratio [OR] 91.51, 5-12 years OR 35.41), states allowing pharmacist-administered influenza vaccination at younger ages (no age restrictions OR, 26.68, minimum age 2-4 years old OR, 33.76), influenza vaccination outside of pediatricians' offices in the previous year (pharmacist-administered OR, 22.18, convenience care OR 4.15, emergency care OR 1.69), geographic region (South OR, 2.02, Midwest OR 1.60, and West OR 1.38), and routine health exam or follow-up in the prior 6-months (OR, 1.59). Conclusions: The strongest drivers of pharmacist-administered pediatric influenza vaccination were older pediatric age, more lenient minimum age restrictions, and previous influenza vaccination in a pharmacy. Due to the COVID-19 pandemic, the PREP Act, and forthcoming pediatric COVID-19 vaccines for children, pharmacists may play a greater role in pediatric vaccination resulting in sustained changes in pediatric vaccination practices.

Secukinumab for children and adolescents with enthesitis-related arthritis and psoriatic arthritis: lessons from treatment in adults and the way forward

INTRODUCTION

Targeting IL-17A using Secukinumab, a humanized monoclonal immunoglobulin G1 (IgG1)/κ against IL-17A is a therapeutic option for immune-mediated disorders such as psoriasis and ankylosing spondylitis. The US Food and Drug Administration and the European Medicines Agency have approved it for the treatment of moderate to severe plaque psoriasis, active psoriatic arthritis, ankylosing spondylitis, and non-radiographic axial spondylarthritis. Recently it has also been approved for use in children with severe plaque psoriasis, active psoriatic arthritis, and enthesitis-related arthritis.

AREAS COVERED

This review focuses on the role of Secukinumab in the management of children and adolescents with enthesitis-related arthritis and psoriatic arthritis. We discuss the salient findings of pivotal RCTs and other studies supporting the use of Secukinumab in adults and children, in particular, focusing on its safety and efficacy.

EXPERT OPINION

Secukinumab is a therapeutic target for psoriasis, psoriatic arthritis, and spondyloarthropathies in both adults and children. No major safety signals are observed with its use in short-term follow-up. Thus far, Secukinumab has not been found to significantly increase the risk of tuberculosis (TB).

Effectiveness and Safety of Direct-acting Antivirals for Treatment of Adolescents With HCV/HIV Coinfection: Real-world Data From Europe

We evaluated the effectiveness and safety of direct-acting antivirals in adolescents with hepatitis C (HCV)/HIV coinfection using pooled individual patient-level data from 5 European cohorts. Of 122 participants in follow-up from November 2013 to August 2021, 19 were treated <18 years of age; of 15 with HCV RNA available at/after 12 weeks post-treatment, all had sustained virologic response with acceptable safety. This evidence addresses an important gap in knowledge of treatment outcomes in adolescents with HCV/HIV coinfection in real-life settings.

Recovery Trajectories in Children Requiring 3 or More Days of Invasive Ventilation

OBJECTIVES

To characterize health-related quality of life (HRQL) and functional recovery trajectories and risk factors for prolonged impairments among critically ill children receiving greater than or equal to 3 days of invasive ventilation.

DESIGN

Prospective cohort study.

SETTING

Quaternary children's hospital PICU.

PATIENTS

Children without a preexisting tracheostomy who received greater than or equal to 3 days of invasive ventilation, survived hospitalization, and completed greater than or equal to 1 postdischarge data collection.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

We evaluated 144 children measuring HRQL using proxy-report Pediatric Quality of Life Inventory and functional status using the Functional Status Scale (FSS) reflecting preillness baseline, PICU and hospital discharge, and 1, 3, 6, and 12 months after hospital discharge. They had a median age of 5.3 years (interquartile range, 1.1-13.0 yr), 58 (40%) were female, 45 (31%) had a complex chronic condition, and 110 (76%) had normal preillness FSS scores. Respiratory failure etiologies included lung disease ( n = 49; 34%), neurologic failure ( n = 23; 16%), and septic shock ( n = 22; 15%). At 1-month postdischarge, 68 of 122 (56%) reported worsened HRQL and 35 (29%) had a new functional impairment compared with preillness baseline. This improved at 3 months to 54 (46%) and 24 (20%), respectively, and remained stable through the remaining 9 months of follow-up. We used interaction forests to evaluate relative variable importance including pairwise interactions and found that therapy consultation within 3 days of intubation was associated with better HRQL recovery in older patients and those with better preillness physical HRQL. During the postdischarge year, 76 patients (53%) had an emergency department visit or hospitalization, and 62 (43%) newly received physical, occupational, or speech therapy.

CONCLUSIONS

Impairments in HRQL and functional status as well as health resource use were common among children with acute respiratory failure. Early therapy consultation was a modifiable characteristic associated with shorter duration of worsened HRQL in older patients.

GRASP reconstruction amplified with view-sharing and KWIC filtering reduces underestimation of peak velocity in highly-accelerated real-time phase-contrast MRI: A preliminary evaluation in pediatric patients with congenital heart disease

PURPOSE

To develop a highly-accelerated, real-time phase contrast (rtPC) MRI pulse sequence with 40 fps frame rate (25 ms effective temporal resolution).

METHODS

Highly-accelerated golden-angle radial sparse parallel (GRASP) with over regularization may result in temporal blurring, which in turn causes underestimation of peak velocity. Thus, we amplified GRASP performance by synergistically combining view-sharing (VS) and k-space weighted image contrast (KWIC) filtering. In 17 pediatric patients with congenital heart disease (CHD), the conventional GRASP and the proposed GRASP amplified by VS and KWIC (or GRASP + VS + KWIC) reconstruction for rtPC MRI were compared with respect to clinical standard PC MRI in measuring hemodynamic parameters (peak velocity, forward volume, backward volume, regurgitant fraction) at four locations (aortic valve, pulmonary valve, left and right pulmonary arteries).

RESULTS

The proposed reconstruction method (GRASP + VS + KWIC) achieved better effective spatial resolution (i.e., image sharpness) compared with conventional GRASP, ultimately reducing the underestimation of peak velocity from 17.4% to 6.4%. The hemodynamic metrics (peak velocity, volumes) were not significantly (p > 0.99) different between GRASP + VS + KWIC and clinical PC, whereas peak velocity was significantly (p < 0.007) lower for conventional GRASP. RtPC with GRASP + VS + KWIC also showed the ability to assess beat-to-beat variation and detect the highest peak among peaks.

CONCLUSION

The synergistic combination of GRASP, VS, and KWIC achieves 25 ms effective temporal resolution (40 fps frame rate), while minimizing the underestimation of peak velocity compared with conventional GRASP.

Adenoid cystic carcinoma of the parotid and submandibular glands in children and young adults: A population-based study

OBJECTIVES

This study aims to analyze the behavior and treatment of adenoid cystic carcinoma (AdCC) in the pediatric and young adult population and to identify factors affecting overall survival (OS).

MATERIALS AND METHODS

The study analyzed salivary gland malignancies in patients aged 0-21 with AdCC histology using the National Cancer Database from 2004 to 2018.

RESULTS

A total of 72 patients (59.7% parotid, 36.1% submandibular, 1.4% sublingual, 2.8% unspecified) met criteria. Median age was 18 years [range: 0-21]. High-grade dysplasia was present in 67% of cases. Therapy consisted of primary surgery for all cases, regional lymph node dissection (LND) (74%), radiotherapy (71%), chemotherapy (8%), and chemoradiation (7%). The 5-year OS rate was 93.2% [95% confidence interval (CI): 86.9%-99.9%], respectively. Patients who underwent associated LND had improved OS (p = .0083, log-rank test) with a 5-year OS at 82.4% [95% CI: 66.1%-100%] versus 97.6% [95% CI: 93.0%-100%]. A significant difference in OS was found with unfavorable outcomes after positive marginal status: 5-year OS 84.1% [95% CI: 71.0%-99.7%] versus 100% [95% CI: 100%]; p < .001. Adjuvant therapy did not seem to impact the outcome.

CONCLUSION

This study confirms that AdCC in children and young adults has an overall good prognosis despite frequent high grade. It suggests that cervical LND may be of importance, but the value of systematic adjuvant therapy is not confirmed. These findings emphasize the importance and relevance of population-based studies in shaping clinical practice and informing the design of future prospective investigations.

Factors Associated with Symptom Resolution after Aerobic Exercise Intervention in Adolescent and Young Adults with Concussion

BACKGROUND

Aerobic exercise facilitates postconcussion symptom resolution at the group level, but patient-level characteristics may affect the likelihood of treatment efficacy.

PURPOSE

This study aimed to investigate demographic and clinical characteristics, which differentiate postconcussion aerobic exercise treatment efficacy from nonefficacy in the intervention arm of a randomized clinical trial.

METHODS

Adolescent and young adult participants initiated a standardized aerobic exercise intervention within 14 d of concussion, consisting of self-selected exercise for 100 min·wk -1 at an individualized heart rate (80% of heart rate induced symptom exacerbation during graded exercise testing). Treatment efficacy was defined as symptom resolution within 28-d postconcussion. Treatment efficacy and nonefficacy groups were compared on demographics, clinical characteristics, intervention adherence, and persistent symptom risk using the Predicting Persistent Postconcussive Problems in Pediatrics (5P) clinical risk score.

RESULTS

A total of 27 participants (16.1 ± 2.3 yr old; range, 11-21 yr; 52% female) began the intervention, with a mean of 9.5 ± 3.7 d after concussion; half ( n = 13; 48%) demonstrated treatment efficacy (symptom resolution within 28 d postconcussion). Those whose symptoms resolved within 28 d had significantly lower preintervention postconcussion symptom inventory scores (21.2 ± 13.2 vs 41.4 ± 22.2; P < 0.01), greater adherence to the intervention (77% vs 36%; P = 0.05), and longer average exercise duration (median [interquartile range], 49.7 [36.8-68.6] vs 30.4 [20.7-34.7] min; P < 0.01) than those whose symptoms lasted more than 28 d. Groups were similar in age, sex, timing of intervention, and preintervention 5P risk score.

CONCLUSIONS

A standardized aerobic exercise intervention initiated within 14 d of concussion demonstrated efficacy for approximately half of participants, according to our definition of treatment efficacy. This multisite aerobic exercise intervention suggests that lower symptom severity, higher intervention adherence, and greater exercise duration are factors that increase the likelihood of symptoms resolving within 28 d of concussion.

Plasma Protein Biomarkers Distinguish Multisystem Inflammatory Syndrome in Children From Other Pediatric Infectious and Inflammatory Diseases

BACKGROUND

Multisystem inflammatory syndrome in children (MIS-C) is a rare but serious hyperinflammatory complication following infection with severe acute respiratory syndrome coronavirus 2. The mechanisms underpinning the pathophysiology of MIS-C are poorly understood. Moreover, clinically distinguishing MIS-C from other childhood infectious and inflammatory conditions, such as Kawasaki disease or severe bacterial and viral infections, is challenging due to overlapping clinical and laboratory features. We aimed to determine a set of plasma protein biomarkers that could discriminate MIS-C from those other diseases.

METHODS

Seven candidate protein biomarkers for MIS-C were selected based on literature and from whole blood RNA sequencing data from patients with MIS-C and other diseases. Plasma concentrations of ARG1, CCL20, CD163, CORIN, CXCL9, PCSK9 and ADAMTS2 were quantified in MIS-C (n = 22), Kawasaki disease (n = 23), definite bacterial (n = 28) and viral (n = 27) disease and healthy controls (n = 8). Logistic regression models were used to determine the discriminatory ability of individual proteins and protein combinations to identify MIS-C and association with severity of illness.

RESULTS

Plasma levels of CD163, CXCL9 and PCSK9 were significantly elevated in MIS-C with a combined area under the receiver operating characteristic curve of 85.7% (95% confidence interval: 76.6%-94.8%) for discriminating MIS-C from other childhood diseases. Lower ARG1 and CORIN plasma levels were significantly associated with severe MIS-C cases requiring inotropes, pediatric intensive care unit admission or with shock.

CONCLUSION

Our findings demonstrate the feasibility of a host protein biomarker signature for MIS-C and may provide new insight into its pathophysiology.

Pattern of use and clinical outcomes with rIX-FP in pediatric/adolescent patients with haemophilia B in Italy: Results from IDEAL real-world study

OBJECTIVES

To evaluate pattern of use and clinical outcomes in pediatric/adolescent patients enrolled in the IDEAL study.

METHODS

This post-hoc analysis of IDEAL retrospective-prospective observational study focused on patients <18 years, 100% on prophylaxis during the entire observation period.

RESULTS

Thirteen subjects (median age 10.0 years; 61.5% ≤ 11 years) were analyzed. The infusion frequency changed from 2/week in 84.6% (N = 11) of patients with previous rFIX, to less than 1/weekly in 76.9% (N = 9) with rIX-FP and the annualized number of infusions reduced of 57% (p = .002), from a mean ± SD of 95.1 ± 22.77 to 40.4 ± 6.79, respectively. Annualized mean consumption decreased of about 56% (p = .001), from 3748.4 ± 1155.40 IU/kg with previous rFIX, to 1656.8 ± 456.63 IU/kg of rIX-FP. Mean FIX trough level changed from 3.0% ± 1.98% to 10.92% ± 3.6%. Low mean Annualized Bleeding Rate was maintained across all prophylaxis regimens (0.8 ± 1.69 vs. 0.3 ± 0.89) and zero bleeding patients moved from 69.2% (N = 9) with previous rFIX to 84.6% (N = 11) with rIX-FP (p = .63). Two adverse events, none related to rIX-FP, occurred in two patients. No inhibitors development was reported.

CONCLUSIONS

The results in this pediatric/adolescent subgroup support rIX-FP prophylaxis may reduce infusion frequency, while providing high FIX trough levels, stable annualized bleeding rate and a good safety profile.

A novel approach to reducing hepatotoxicity related to fungal prophylaxis in pediatric lung transplant recipients

BACKGROUND

Pediatric lung transplant patients are at risk for developing invasive fungal infections post-transplant. No consensus exists on optimal antifungal regimens and voriconazole, a common first-line agent, has been shown to cause hepatotoxicity. We describe a single-center experience utilizing a novel antifungal regimen of intravenous micafungin and nebulized amphotericin B immediately post-transplant with conversion to an azole at the time of hospital discharge and compare it to a historical cohort of patients who received voriconazole monotherapy throughout their immediate post-operative course.

METHODS

This is a retrospective review of patients in the age 0-18 who received a lung transplant from June 2016-May 2021. Data points collected included: demographic data, transplant date and discharge date, Aspergillus colonization, type of lung transplant, hospitalization and level of care information, induction and antifungal medication regimen; AST, ALT, GGT, bilirubin, and direct bilirubin at various timepoints; and respiratory and blood culture results. The two patient groups were compared by assessment of changes in LFTs and culture results.

RESULTS

Forty-two patients were included in the analysis, with 24 patients receiving micafungin and nebulized amphotericin and 18 patients receiving voriconazole. All patients in both groups experienced a post-operative elevation in at least one transaminase or bilirubin. More patients in the micafungin/amphotericin group had resolution of all abnormal LFTs by 1 month post-transplant (p = .036). Additionally, patients in the micafungin/amphotericin group experienced faster normalization of their LFTs compared with the voriconazole group (p < .001). Ten patients in the micafungin/amphotericin group and five patients in the voriconazole group were found to have fungal growth on culture post-transplant, but this difference was not found to be statistically significant (p = .507).

CONCLUSIONS

An antifungal regimen of micafungin and nebulized amphotericin B liposomal may be useful at decreasing the duration of elevated liver enzymes in pediatric patients in the immediate post-lung transplant period when compared with voriconazole monotherapy. Larger prospective studies looking at antifungal regimens in pediatric patients post-lung transplant are warranted.

Comparing apples to apples: Exploring public reporting of congenital cardiac surgery outcomes based on common congenital heart operations

OBJECTIVE

We sought to simplify reporting of outcomes in congenital heart surgery that compares well-defined patient groups and accommodates multiple stakeholder needs while being easily understandable.

METHODS

We selected 19 commonly performed congenital heart surgeries ranging in complexity from repair of atrial septal defects to the Norwood procedure. Strict inclusion/exclusion criteria ensured the creation of 19 well-defined diagnosis/procedure cohorts. Preoperative, procedural, and postoperative data were collected for consecutive eligible patients from 9 centers between January 1, 2016, and December 31, 2021. Unadjusted operative mortality rates and hospital length of stay for each of the 19 diagnosis/procedure cohorts were summarized in aggregate and stratified by each center.

RESULTS

Of 8572 eligible cases included, numbers in the 19 diagnosis/procedure cohorts ranged from 73 for tetralogy of Fallot repair after previous palliation to 1224 for ventricular septal defect (VSD) repair for isolated VSD. In aggregate, the unadjusted mortality ranged from 0% for atrial septal defect repair to 28.4% for hybrid stage I. There was significant heterogeneity in case mix and mortality for different diagnosis/procedure cohorts across centers (eg, arterial switch operation/VSD, n = 7-42, mortality 0%-7.4%; Norwood procedure, n = 16-122, mortality 5.3%-25%).

CONCLUSIONS

Reporting of institutional case volumes and outcomes within well-defined diagnosis/procedure cohorts can enable centers to benchmark outcomes, understand trends in mortality, and direct quality improvement. When made public, this type of report could provide parents with information on institutional volumes and outcomes and allow them to better understand the experience of each program with operations for specific congenital heart defects.

Delayed diagnostic interval and survival outcomes in pediatric leukemia: A single-center, retrospective study

OBJECTIVE

This study primarily focused on the diagnostic interval (DI), defined as the duration from the onset of leukemic symptoms to diagnosis. We investigated whether a prolonged DI is associated with the outcomes of pediatric leukemia.

METHODS

We retrospectively collected data of children with newly diagnosed pediatric leukemia at Okayama University Hospital from January 2007 to December 2022. Survival analyses were conducted using Kaplan-Meier methods, and an unadjusted analysis to compare differences in survival was performed using the log-rank test.

RESULTS

In total, 103 children with leukemia were included in the analysis. The median DI was 20 days (interquartile range, 9.5-33.5 days). A prolonged DI (≥30 days) demonstrated no association with either 5-year event-free survival (70.1% for <30 days and 68.3% for ≥30 days, p = .99, log-rank test) or overall survival (84.7% for <30 days and 89.4% for ≥30 days, p = .85, log-rank test).

CONCLUSIONS

A prolonged DI was not associated with the survival of children with leukemia. If a precise classification of leukemia biology is provided for pediatric patients, a prolonged DI may have little impact on the prognosis of these patients.

Absolute neutrophil count clinical trial eligibility criteria for pediatric oncology phase I and phase I/II trials by sponsorship

Normal absolute neutrophil count (ANC) variations, as seen with Duffy-null associated neutrophil count (DANC), are not accounted for in trial eligibility, which may contribute to racial enrollment disparities. We describe ANC eligibility for pediatric oncology phase I/II clinical trials according to primary sponsorship from 2010 to 2023 using ClinicalTrials.gov. Out of 438 trials, 20% were industry-sponsored. Total 17% of trials required ANC ≥1500 cells/μL for enrollment; however, industry-sponsored trials were significantly more likely to require ANC ≥1500 cells/μL than non-industry-sponsored trials (odds ratio 2.53, 95% confidence interval: 1.39-4.62; p < .001). These data suggest laboratory exclusion criteria are one possible mechanism for pediatric clinical trial enrollment disparities.

Prognostic Communication Between Parents and Clinicians in Pediatric Oncology: An Integrative Review

Background: Prognostic communication between clinicians and parents in pediatric oncology is complex. However, no review has exclusively examined research on prognostic communication in pediatric oncology. In this review, we synthesize the evidence on prognostic communication in pediatric oncology and provide recommendations for future research. Methods: We conducted an integrative review searching six databases for studies on prognostic communication in pediatric oncology as of August 2022. We applied descriptive and narrative approaches to data analysis. Results: Fourteen quantitative and five qualitative studies were included. All studies were conducted in Western developed countries. In total, 804 parents of 770 children with cancer were included. Across studies, parents were predominately female, Non-Hispanic White, and had high school or higher levels of education. Most parents reported that prognostic communication was initiated in the first year after their children's diagnosis. High-quality prognostic communication was positively associated with trust and hope and negatively associated with parental distress and decisional regret. In qualitative studies, parents suggested that prognostic communication should be open, ongoing, and delivered with sensitivity. Most studies were of moderate quality. The main gaps included inconsistent definitions of prognostic communication, and a lack of comprehensive and validated measurements, high-quality longitudinal studies, and diverse settings and participants. Conclusions: Clinicians should initiate high-quality prognostic communication early on in clinical practice. Future research should consider conducting high-quality longitudinal studies, developing prognostic communication definitions and measurements, and conducting studies across settings with diverse populations.

Evaluation of Focused Assessment With Sonography for Trauma Completeness of Children in the Clinical Setting

OBJECTIVES

We evaluated the completeness of real-world Focused Assessment with Sonography for Trauma (FAST) in children after blunt abdominal trauma by benchmarking against established expert guidelines.

METHODS

We conducted a retrospective cohort study, analyzing a random sample of FASTs from two urban pediatric emergency departments. Two experts reviewed and labeled all FASTs for completeness using a predefined guideline of 5 anatomic views and 30 landmarks. We compared frequencies of views and landmarks as medians with interquartile ranges.

RESULTS

We analyzed 200 FASTs, consisting of 1636 video clips, performed by 31 clinicians representing 198 children with a median age of 10 years (IQR 5,14). Over half of FASTs (52%) had all 5 views. The right upper quadrant view was most commonly visualized (96.5%), and suprapubic sagittal was least (65%). None of the FASTs included all 30 landmarks, ranging from 0 to 28 and median of 19 (IQR 15,23). The least visualized landmark of the right and left upper quadrants was caudal liver edge (60%) and splenic tip (64%), respectively. In the pericardial view, it was left atrium (45%). In both transverse and sagittal pelvic views, retro-uterine space was least visualized in girls, 21 and 29% respectively.

CONCLUSIONS

In our study, most FAST views and landmarks were visualized. However, the pelvic sagittal view was the least frequently visualized view, and caudal liver edge was the least visualized landmark. Future research should evaluate if variability in visualizing FAST views and landmarks correlates with inconsistencies in diagnostic test performance.

Shifting perspectives and transformative change: Parent perspectives of an active music engagement intervention for themselves and their child with cancer

BACKGROUND

Children with cancer (ages 3-8 years) and their parents experience significant, interrelated distress associated with cancer treatment. Active music engagement (AME) uses music-based play and shared music-making to mitigate this distress. To advance our understanding about how AME works and its essential features, we interviewed parents who received the AME intervention as part of a multi-site mechanistic trial. The purpose of this qualitative analysis was to describe parents' experiences of AME for themselves and their child and to better understand how the intervention worked to lower parent-child distress.

PROCEDURE

We conducted a total of 43 interviews with parents/caregivers, and purposively analyzed all interviews from underrepresented groups based on race/ethnicity and parent role. We used thematic analysis and achieved thematic redundancy after analyzing 28 interviews.

RESULTS

The following statement summarizes resulting themes: Music therapists skillfully use AME to create a safe and healthy space (Theme 1), where parents/children have transformative experiences (Theme 2) that lead to learning and enactment (Theme 3) of new skills that counteract suffering (Theme 4) through empowerment, connectedness, and sustained relief.

CONCLUSIONS

This work elucidates how AME works to counteract stressful qualities of cancer treatment. As parents witnessed positive and transformative changes in their child, they experienced relief and reported shifts in their perspective about cancer treatment. This led to learning and use of music as a coping strategy that extended beyond therapist-led sessions. Accessible, music-based interventions, like AME, offer a developmentally appropriate and effective way to support parents and young children during treatment.

Associations between Medicaid enrollment and diagnosis stage and survival among pediatric cancer patients

BACKGROUND

Medicaid-associated disparities in childhood and adolescent (pediatric) cancer diagnosis stage and survival have been reported. However, a key limitation of prior studies is the assessment of health insurance at a single time point. To evaluate Medicaid-associated disparities more robustly, we used Surveillance, Epidemiology, and End Results (SEER)-Medicaid linked data to examine diagnosis stage and survival disparities in those (i) Medicaid-enrolled and (ii) with discontinuous and continuous Medicaid enrollment.

METHODS

SEER-Medicaid linked data from 2006 to 2013 were obtained on cases diagnosed from 0 to 19 years. Medicaid enrollment was classified as enrolled versus not enrolled, with further classifications as continuous when enrolled 6 months before through 6 months after diagnosis, and discontinuous when not enrolled continuously for this period. We used multinomial logistic and Cox proportional hazards regression models to determine associations between enrollment measures, diagnosis stage, and cancer death adjusted for covariates.

RESULTS

Among 21,502 cases, a higher odds of distant stage diagnoses were observed in association with Medicaid enrollment (odds ratio [OR] = 1.56, 95% confidence interval [CI]: 1.48-1.65), with the highest odds for discontinuous enrollment (OR = 2.0, 95% CI: 1.86-2.15). Among 30,654 cases, any Medicaid enrollment, continuous enrollment, and discontinuous enrollment were associated with 1.68 (95% CI: 1.35-2.10), 1.66 (95% CI: 1.35-2.05), and 1.89 (95% CI: 1.54-2.33) times higher hazards of cancer death versus no enrollment, respectively.

CONCLUSIONS

Medicaid enrollment, particularly discontinuous enrollment, is associated with a higher  distant stage diagnosis odds and risk of death. This study supports the critical need for consistent health insurance coverage in children and adolescents.

Sirolimus for Pediatric Cervicofacial Lymphatic Malformation: A Systematic Review and Meta-Analysis

OBJECTIVE

This study is a systematic review and meta-analysis of the efficacy and safety of sirolimus in the management of pediatric cervicofacial lymphatic malformations (LMs).

DATA SOURCES

EMBASE, Medline, Scopus, and Cochrane databases were searched, along with the reference list of all included articles.

REVIEW METHODS

The study protocol was registered with PROSPERO and a systematic literature search strategy was designed and conducted with the aid of a medical librarian. All studies including case reports were included, with pooled analysis of raw data. A meta-analysis was conducted of magnetic resonance imaging (MRI), clinical, and airway outcomes.

RESULTS

Thirteen case series and five individual case reports were included. Meta-analysis showed 78% (95% CI 57%-94%) of 62 patients had a reduction in LM volume, on MRI criteria, by 20% or more, and 32% (95% CI 11%-57%) had a reduction of 50% or more. Further meta-analysis showed 97% (95% CI 88%-100%) of 78 patients reported some clinical improvement on sirolimus. Sirolimus may be of particular value in management of airway LMs; out of 27 tracheostomy-dependent patients, meta-analysis showed 33% (95% CI 1%-78%) were decannulated after starting sirolimus. Individual patient meta-analysis on 24 individuals showed a statistically significant better response to sirolimus when initiated under the age of 2 years.

CONCLUSION

This review and meta-analysis support the efficacy of sirolimus in pediatric LMs of the head, neck, and airway. A large multi-center trial is needed to further explore its role and limitations. Laryngoscope, 134:2038-2047, 2024.

Perioperative methadone for posterior spinal fusion in adolescents: Results from a double-blind randomized-controlled trial

BACKGROUND

Posterior spinal fusion is the most common surgical procedure performed for correction of adolescent idiopathic scoliosis in the United States. Intraoperative methadone has been shown to improve pain control in adult patients undergoing complex spine surgery, and current pediatric studies show encouraging results; however, prospective randomized-controlled trials are lacking in the pediatric literature.

AIMS

We conducted a single-center double-blind randomized-controlled trial to compare intraoperative use of methadone to morphine in pediatric patients undergoing posterior spinal fusion.

METHODS

A total of 47 adolescents undergoing posterior spinal fusion were randomized (stratified by sex) to either a methadone (n = 25) or morphine (n = 22) group. The primary outcome was postoperative opioid consumption. Secondary outcomes included postoperative pain severity, opioid-related side effects, and ratio of patient-controlled analgesia injections: attempts as a behavioral index of uncontrolled pain.

RESULTS

Patients in the methadone group consumed less total opioid postoperatively (median [interquartile range], 0.3 mg/kg [0.1, 0.5]) than patients in the morphine group (0.3 mg/kg [0.2, 0.6]), median difference [95% confidence interval] -0.07 [-0.2 to 0.02]; (p = .026). Despite the lower amount of opioid used postoperatively, pain scores for the methadone group (3.5 [3.0, 4.3]) were not significantly different from those in the morphine group (4.0 [3.2, 5.0]; p = .250). Groups did not differ on opioid-related side effects.

CONCLUSIONS

A two-dose intraoperative methadone regimen resulted in decreased opioid consumption compared to morphine. Although the clinical significance of these results may be limited, the analgesic equipoise without increased opioid-related side effects and potential for a lower incidence of chronic pain may tip the balance in favor of routine methadone use for adolescents undergoing posterior spinal fusion.

Let's get physical: Aerobic capacity, muscle strength, and muscle endurance after pediatric heart transplantation

BACKGROUND

Pediatric heart (HTx) and kidney transplant (KTx) recipients may have lower physical fitness than healthy children. This study sought to quantify fitness levels in transplant recipients, investigate associations to clinical factors and quality of life, and identify whether a quick, simple wall-sit test is feasible as a surrogate for overall fitness for longitudinal assessment.

METHODS

Aerobic capacity (6-min walk test, 6MWT), normalized muscle strength, muscle endurance, physical activity questionnaire (PAQ), and quality of life (PedsQL™) were prospectively assessed in transplanted children and matched healthy controls.

RESULTS

Twenty-two HTx were compared to 20 controls and 6 KTx. 6MWT %predicted was shorter in HTx (87.2 [69.9-118.6] %) than controls (99.9 [80.4-120] %), but similar to KTx (90.3 [78.6-115] %). Muscle strength was lower in HTx deltoids (6.15 [4.35-11.3] kg/m2) and KTx quadriceps (9.27 [8.65-19.1] kg/m2) versus controls. Similarly, muscle endurance was lower in HTx push-ups (28.6 [0-250] %predicted), KTx push-ups (8.35 [0-150] %predicted), HTx curl-ups (115 [0-450] %predicted), and KTx wall-sit time (18.5 [10.0-54.0] s) than controls. In contrast to HTx with only 9%, all KTx were receiving steroid therapy. The wall-sit test significantly correlated with other fitness parameters (normalized quadriceps strength R = .31, #push-ups R = .39, and #curl-ups R = .43) and PedsQL™ (R = .36).

CONCLUSIONS

Compared to controls, pediatric HTx and KTx have similarly lower aerobic capacity, but different deficits in muscle strength, likely related to steroid therapy in KTx. The convenient wall-sit test correlates with fitness and reported quality of life, and thus could be a useful easy routine for longitudinal assessment.

Identification of Irpex and Rhodotorula on surveillance bronchoscopy in a pediatric lung transplant recipient: A case report and review of literature of these atypical fungal organisms

BACKGROUND

Invasive fungal disease (IFD) is a frequent complication in pediatric lung transplant recipients, occurring in up to 12% of patients in the first year. Risk factors for infection include impaired lung defenses and intense immunosuppressive regimens. While most IFD occurs from Aspergillus, other fungal conidia are continuously inhaled, and infections with fungi on a spectrum of human pathogenicity can occur.

CASE REPORT

We report a case of a 17-year-old lung transplant recipient in whom Irpex lacteus and Rhodotorula species were identified during surveillance bronchoscopy. She was asymptomatic and deemed to be colonized by Irpex lacteus and Rhodotorula species following transplant. 2 years after transplantation, she developed a fever, respiratory symptoms, abnormal lung imaging, and histological evidence of acute and chronic bronchitis on transbronchial biopsy. After developing symptoms concerning for a pulmonary infection and graft dysfunction, she was treated for a presumed IFD. Unfortunately, further diagnostic testing could not be performed at this time given her tenuous clinical status. Despite the initiation of antifungal therapy, her graft function continued to decline resulting in a second lung transplantation.

CONCLUSIONS

This case raises the concern for IFD in lung transplant recipients from Irpex species. Further investigation is needed to understand the pathogenicity of this organism, reduce the incidence and mortality of IFD in lung transplant recipients, and refine the approach to diagnosis and manage the colonization and isolation of rare, atypical fungal pathogens in immunocompromised hosts.

Pediatric Orthognathic Surgery: A NSQIP-P Comparison of Peri-Operative Factors and Outcome Differences Between Cleft and Noncleft Patients

OBJECTIVE

The present study aimed to investigate the risk factors, complication profiles, and clinical outcomes of cleft and noncleft patients undergoing single jaw (mandibular or LeFort 1) and bimaxillary (BSSO + LeFort 1).

DESIGN

Retrospective Cross-sectional Study Setting: National Surgical Quality Improvement Program database 2018-2019.

PATIENTS

Pediatric patients.

INTERVENTIONS

Outcomes for mandibular, LeFort 1, and bimaxillary osteotomy were retrospectively evaluated for cleft and noncleft patients.

MAIN OUTCOME MEASURES

Multivariate logistic regression was used to determine the odds of complications and length of stay for cleft and noncleft patients undergoing single jaw and double jaw surgery.

RESULTS

669 pediatric patient underwent orthognathic surgery in the study period; the majority received LF1 only (n = 385; 58.3%), followed by mandible only (n = 179; 27.1%), and bimaxillary (n = 105; 15.9%%). Cleft differences were present in 56% of LFI patients, 32% of mandibular patients, and 22% of bimaxillary patients. After multivariate adjustment, ASA class III was associated with nearly 400% increased odds of any complication including readmission and reoperation (OR = 5.99; CI [[1.54-23.32]], p < 0.01, and 65% increased LOS (β-coefficient = 1.65, CI [1.37-1.99], p < 0.01). Presence of cleft was not significantly associated with odds of any complication (p = 0.69) nor increased LOS (p = 0.46) in this population.

CONCLUSION

Complications remained low between surgery types among cleft and noncleft patients. The most significant risk factor in pediatric orthognathic surgery was not the presence of cleft but rather increased ASA class. Though common in patients seeking orthognathic surgery, cleft differences did not cause additional risk after adjustment for other variables.

Incidence rate and prevalence of pediatric-onset multiple sclerosis in Sweden: A population-based register study

BACKGROUND AND PURPOSE

Pediatric-onset multiple sclerosis (PoMS) is associated with high health care use. To plan resource allocation for this patient group, knowledge of the incidence rate and prevalence is important. However, such studies are scarce, few are population-based, and the methodology varies widely. We aimed to address this knowledge gap by performing a nationwide study of the incidence rate and prevalence of PoMS in Sweden, an area of high multiple sclerosis (MS) incidence and prevalence.

METHODS

MS cases were identified by linking two nationwide registers, the National Patient Register and the Swedish MS Registry. MS cases having their first central nervous system demyelinating event or MS clinical onset before age 18 years were classified as pediatric onset. Incidence rate and prevalence were estimated annually over the study period (2006-2016) for the total population and stratified by sex and age group (<12, 12-15, and 16-17 years). Temporal trends and ratios between sexes and age groups were estimated.

RESULTS

We identified 238 incident cases from 2006 to 2016, corresponding to an overall crude incidence rate of 1.12 per 100,000 person-years and an overall crude prevalence of 2.82 per 100,000 population. There was a higher incidence rate among females and the highest age category. The overall incidence rate and prevalence estimates remained stable during the study period.

CONCLUSIONS

Sweden exhibits a consistently high incidence rate and prevalence of PoMS that has remained stable over time. This knowledge serves as a tool to aid in planning resource allocation and health services for this patient population.

Pediatric donor heart utilization variability among organ procurement organizations

BACKGROUND

Organ procurement organizations (OPOs) are responsible for the medical management of organ donors. Given the variability in pediatric donor heart utilization among OPOs, we examined factors that may explain this variability, including differences in donor medical management, organ quality, and candidate factors.

METHODS

The Organ Procurement and Transplant Network database was queried for pediatric (<18 years) heart donors and candidates receiving pediatric donor heart offers from 2010 to 2019. OPOs were stratified by pediatric donor heart utilization rate, and the top and bottom quintiles were compared based on donor management strategies and outcomes. A machine learning algorithm, combining 11 OPO, donor, candidate, and offer variables, was used to determine factors most predictive of whether a heart offer is accepted.

RESULTS

There was no clinically significant difference between the top and bottom quintile OPOs in baseline donor characteristics, distance between donor and listing center, management strategies, or organ quality. Machine learning modeling suggested neither OPO donor management nor cardiac function is the primary driver of whether an organ is accepted. Instead, number of prior donor offer refusals and individual listing center receiving the offer were two of the most predictive variables of organ acceptance.

CONCLUSIONS

OPO clinical practice variation does not seem to account for the discrepancy in pediatric donor heart utilization rates among OPOs. Listing center acceptance practice and prior number of donor refusals seem to be the important drivers of heart utilization and may at least partially account for the variation in OPO heart utilization rates given the regional association between OPOs and listing centers.

Does UK Entry-Level Physiotherapy Education Prepare Graduates for a Future in Pediatric Clinical Practice? A Mixed-Methods Study

AIMS

Identify the perceptions and experiences of how UK entry-level programs educationally prepared pediatric physiotherapists for their first clinical role. Review the extent programs taught essential, recommended, and additional content as per the International Organisation of Physical Therapists in Pediatrics (IOPTP).

METHODS

Mixed methods design involving qualified UK pediatric physiotherapists. Forty-two physiotherapists completed an online questionnaire and nine (21%) completed a follow-up semi-structured interview.

RESULTS

All 42 respondents felt they were "Not Well" (median 2, IQR 1.75-2.75) prepared for clinical practice. Not enough curricula emphasis was given to pediatric content (100%), with 31% (n = 13, CI 95% 19-46) reporting no pediatric content throughout their program. Only 15 (36%, 23-51) respondents experienced a pediatric placement. Themes from the follow-up interviews were (1) UK programs are adult focused; (2) placements are the only meaningful opportunity to develop competency; (3) programs lacked non-clinical content; and (4) experiencing pediatric patients was overwhelming due poor preparation. The majority of the IOPTP curriculum guidance is not embedded within UK curriculums.

CONCLUSIONS

Respondents reported they were not well prepared for pediatric clinical practice. Some entry-level programs did not include any pediatric teaching throughout the entirety of the course.

Social deprivation index affects time to MRI after knee injury in pediatric patients and is predicted by patient demographics

OBJECTIVES

This study aims to characterize the association between the timing of MRI ordering and completion for pediatric knee injuries and Social Deprivation Index (SDI), which is a comprehensive, validated, county-level, measure of socioeconomic variation in health outcomes based upon combining geography, income, education, employment, housing, household characteristics, and access to transportation.

METHODS

A retrospective chart review was completed of patients 21 years old and younger from our institution with a history of knee sports injury (ligamentous/soft tissue injury, structural abnormality, instability, inflammation) evaluated with MRI between 5/26/2017 and 12/28/2020. Patients were from three states and attended to by physicians associated with an urban academic institution. Patients were assigned SDI scores based on their ZIP code. Excluded from the study were patients with a non-knee related diagnosis (hip, foot, or ankle), patients from ZIP codes with unknown SDI, and non-sports medicine diagnoses (tumor, infection, fracture).

RESULTS

In a multivariate regression analysis of 355 patients, increased SDI was independently associated with increased time from clinic visit to MRI order (p = 0.044) and from clinic visit to MRI completion (p = 0.047). Each 10-point increase in SDI (0-100) was associated with a delay of 7.2 days on average. SDI itself was found to be associated with a patient's race (p < 0.001), ethnicity (p < 0.001), and insurance category (p < 0.001).

CONCLUSION

Increased SDI is independently associated with longer time from clinic visit to knee MRI order and longer time from clinic visit to knee MRI completion in our pediatric population. Recognizing potential barriers to orthopedic care can help create the change necessary to provide the best possible care for all individual patients.

Opioid use disorder in pediatric populations: considerations for perioperative pain management and precision opioid analgesia

INTRODUCTION

Opioids are commonly used for perioperative analgesia, yet children still suffer high rates of severe post-surgical pain and opioid-related adverse effects. Persistent and severe acute surgical pain greatly increases the child's chances of chronic surgical pain, long-term opioid use, and opioid use disorder.

AREAS COVERED

Enhanced recovery after surgery (ERAS) protocols are often inadequate in treating a child's severe surgical pain. Research suggests that 'older' and longer-acting opioids such as methadone are providing better methods to treat acute post-surgical pain. Studies indicate that lower repetitive methadone doses can decrease the incidence of chronic persistent surgical pain (CPSP). Ongoing research explores genetic components influencing severe surgical pain, inadequate opioid analgesia, and opioid use disorder. This new genetic research coupled with better utilization of opioids in the perioperative setting provides hope in personalizing surgical pain management, reducing pain, opioid use, adverse effects, and helping the fight against the opioid pandemic.

EXPERT OPINION

The opioid and analgesic pharmacogenomics approach can proactively 'tailor' a perioperative analgesic plan to each patient based on underlying polygenic risks. This transition from population-based knowledge of pain medicine to individual patient knowledge can transform acute pain medicine and greatly reduce the opioid epidemic's socioeconomic, personal, and psychological strains globally.

Income-Based Disparities in Outcomes Following Pediatric Appendectomy: A National Analysis

BACKGROUND

Appendectomy remains a common pediatric surgical procedure with an estimated 80,000 operations performed each year. While prior work has reported the existence of racial disparities in postoperative outcomes, we sought to characterize potential income-based inequalities using a national cohort.

METHODS

All non-elective pediatric (<18 years) hospitalizations for appendectomy were tabulated in the 2016-2020 National Inpatient Sample. Only those in the highest (HI) and lowest income (LI) quartiles were considered for analysis. Multivariable regression models were developed to assess the independent association of income and postoperative major adverse events (MAE).

RESULTS

Of an estimated 87,830 patients, 36,845 (42.0%) were HI and 50,985 (58.0%) were LI. On average, LI patients were younger (11 [7-14] vs 12 [8-15] years, P < .001), more frequently insured by Medicaid (70.7 vs 27.3%, P < .05), and more commonly of Hispanic ethnicity (50.8 vs 23.4%, P < .001). Following risk adjustment, the LI cohort was associated with greater odds of MAE (adjusted odds ratio [AOR] 1.30 95% confidence interval [CI] 1.06-1.64). Specifically, low-income status was linked with increased odds of infectious (AOR 1.65, 95% CI 1.12-2.42) and respiratory (AOR 1.67, 95% CI 1.06-2.62) complications. Further, LI was associated with a $1670 decrement in costs ([2220-$1120]) and a +.32-day increase in duration of stay (95% CI [.21-.44]).

CONCLUSION

Pediatric patients of the lowest income quartile faced increased risk of major adverse events following appendectomy compared to those of highest income. Novel risk stratification methods and standardized care pathways are needed to ameliorate socioeconomic disparities in postoperative outcomes.

Updates in the treatment of asthma in pediatrics: A review for pharmacists

PURPOSE

The purpose of this review is to summarize the management of asthma in children and to highlight different guideline-based approaches. This review also discusses literature regarding the use of corticosteroids, both inhaled and systemic, as well as biologic agents, in asthma management.

SUMMARY

Asthma is a common chronic respiratory condition in the pediatric population and has evolved into a highly patient-specific disease. Of the 2 main asthma guidelines, one developed by the National Asthma Education and Prevention Program was recently published as a focused update in 2020. The other, from the Global Initiative for Asthma, focuses on a global strategy for management and prevention, with the most recent update in 2023. Both reports discuss diagnosis, assessment, and treatment of asthma in adults and children. Treatment is designed as a stepwise approach in both reports, although there are key differences. This article focuses on gaps in these guidelines, including the use of bronchodilators and inhaled corticosteroids with single maintenance and reliever therapy and long-acting muscarinic antagonists in children. It also reviews treatment in children under 5 years of age, although recommendations are limited due to a lack of evidence in this age group. Finally, this review discusses considerations for emerging treatments, including biologics, for patients who are difficult to treat.

CONCLUSION

New treatment strategies and agents have emerged in the treatment of pediatric asthma. Pharmacists play a key role in providing education about, dispensing, and recommending the newest evidence-based treatment options for children.

Glycemia and Gluconeogenesis With Metformin and Liraglutide: A Randomized Trial in Youth-onset Type 2 Diabetes

OBJECTIVE

Elevated rates of gluconeogenesis are an early pathogenic feature of youth-onset type 2 diabetes (Y-T2D), but targeted first-line therapies are suboptimal, especially in African American (AA) youth. We evaluated glucose-lowering mechanisms of metformin and liraglutide by measuring rates of gluconeogenesis and β-cell function after therapy in AA Y-T2D.

METHODS

In this parallel randomized clinical trial, 22 youth with Y-T2D-age 15.3 ± 2.1 years (mean ± SD), 68% female, body mass index (BMI) 40.1 ± 7.9 kg/m2, duration of diagnosis 1.8 ± 1.3 years-were randomized to metformin alone (Met) or metformin + liraglutide (Lira) (Met + Lira) and evaluated before and after 12 weeks. Stable isotope tracers were used to measure gluconeogenesis [2H2O] and glucose production [6,6-2H2]glucose after an overnight fast and during a continuous meal. β-cell function (sigma) and whole-body insulin sensitivity (mSI) were assessed during a frequently sampled 2-hour oral glucose tolerance test.

RESULTS

At baseline, gluconeogenesis, glucose production, and fasting and 2-hour glucose were comparable in both groups, though Met + Lira had higher hemoglobin A1C. Met + Lira had a greater decrease from baseline in fasting glucose (-2.0 ± 1.3 vs -0.6 ± 0.9 mmol/L, P = .008) and a greater increase in sigma (0.72 ± 0.68 vs -0.05 ± 0.71, P = .03). The change in fractional gluconeogenesis was similar between groups (Met + Lira: -0.36 ± 9.4 vs Met: 0.04 ± 12.3%, P = .9), and there were no changes in prandial gluconeogenesis or mSI. Increased glucose clearance in both groups was related to sigma (r = 0.63, P = .003) but not gluconeogenesis or mSI.

CONCLUSION

Among Y-T2D, metformin with or without liraglutide improved glycemia but did not suppress high rates of gluconeogenesis. Novel therapies that will enhance β-cell function and target the elevated rates of gluconeogenesis in Y-T2D are needed.

The Impact of Spironolactone Co-administration on Cyclosporin Initial Dosage Optimization for Pediatric Refractory Nephrotic Syndrome

OBJECTIVES

Cyclosporin has been used for the treatment of pediatric refractory nephrotic syndrome (PRNS). However, the narrow therapeutic window and large pharmacokinetic variability make it difficult to individualize cyclosporin administration. Meanwhile, spironolactone has been reported to affect cyclosporin metabolism in PRNS patients. This study aims to explore the initial dosage optimization of cyclosporin in PRNS based on the impact of spironolactone co-administration.

METHODS

Monte Carlo simulation based on a previously established cyclosporin population pharmacokinetic model for PRNS was used to design cyclosporin dosing regimen.

RESULTS

In this study, the probability of drug concentration reaching the target and the convenience of times of administration were considered comprehensively. The optimal administration regimen in PRNS without spironolactone was 6, 5, 4 and 3 mg/kg cyclosporin split into two doses for the body weight of 5-8, 8-18, 18-46 and 46-70 kg, respectively. The optimal administration regimen in PRNS with spironolactone was 4, 3, 2 mg/kg cyclosporin split into two doses for body weight of 5-14, 14-65, and 65-70 kg, respectively.

CONCLUSION

The cyclosporin dosing regimen for PRNS based on Monte Carlo simulation was systematically developed and the initial dosage optimization of cyclosporin in PRNS was recommended for the first time.

IKZF1PLUS alterations contribute to outcome disparities in Hispanic/Latino children with B-lymphoblastic leukemia

BACKGROUND

Compared to other ethnicities, Hispanics/Latinos (H/L) have a high incidence of acute lymphoblastic leukemia (ALL), enrichment of unfavorable ALL genetic subtypes, and worse outcomes, even after correcting for socioeconomic factors. We previously demonstrated increased incidence of the high-risk genetic drivers IKZF1 deletion and IGH::CRLF2 rearrangement in H/L compared to non-H/L children with B-ALL. Here in an expanded pediatric cohort, we sought to identify novel genetic drivers and secondary genetic alterations in B-ALL associated with H/L ethnicity.

PROCEDURE

Comprehensive clinicopathologic data from patients with B-ALL treated from 2016 to 2020 were analyzed. Subtype was determined from karyotype, fluorescence in situ hybridization (FISH), chromosome microarray (CMA), and our next-generation sequencing (NGS) panel (OncoKids). Non-driver genetic variants were also examined. p-Values less than .05 (Fisher's exact test) were considered significant.

RESULTS

Among patients with B-ALL at diagnosis (n = 273), H/L patients (189, 69.2%) were older (p = .018), more likely to present with CNS2 or CNS3 disease (p = .004), and NCI high-risk ALL (p = .014) compared to non-H/L patients. Higher incidence of IGH::CRLF2 rearrangement (B-ALL, BCR::ABL1-like, unfavorable; p = .016) and lower incidence of ETV6::RUNX1 rearrangement (favorable, p = .02) were also associated with H/L ethnicity. Among secondary (non-subtype-defining) genetic variants, B-ALL in H/L was associated with IKFZ1 deletion alone (p = .001) or with IGH::CRLF2 rearrangement (p = .003). The IKZF1PLUS profile (IKZF1 deletion plus CDKN2A/2Bdel, PAX5del, or P2RY8::CRLF2 rearrangement without DUX4 rearrangement) was identified as a novel high-risk feature enriched in H/L patients (p = .001).

CONCLUSIONS

Our study shows enrichment of high-risk genetic variants in H/L B-ALL and raises consideration for novel therapeutic targets.

Forecasting Hepatitis C Virus Status for Children in the United States: A Modeling Study

BACKGROUND

Virtually all cases of hepatitis C virus (HCV) infection in children in the United States occur through vertical transmission, but it is unknown how many children are infected. Cases of maternal HCV infection have increased in the United States, which may increase the number of children vertically infected with HCV. Infection has long-term consequences for a child's health, but treatment options are now available for children ≥3 years old. Reducing HCV infections in adults could decrease HCV infections in children.

METHODS

Using a stochastic compartmental model, we forecasted incidence of HCV infections in children in the United States from 2022 through 2027. The model considered vertical transmission to children <13 years old and horizontal transmission among individuals 13-49 years old. We obtained model parameters and initial conditions from the literature and the Centers for Disease Control and Prevention's 2021 Viral Hepatitis Surveillance Report.

RESULTS

Model simulations assuming direct-acting antiviral treatment for children forecasted that the number of acutely infected children would decrease slightly and the number of chronically infected children would decrease even more. Alone, treatment and early screening in individuals 13-49 years old reduced the number of forecasted cases in children and, together, these policy interventions were even more effective.

CONCLUSIONS

Based on our simulations, acute and chronic cases of HCV infection are remaining constant or slightly decreasing in the United States. Improving early screening and increasing access to treatment in adults may be an effective strategy for reducing the number of HCV infected children in the United States.

Myosin inhibitor reverses hypertrophic cardiomyopathy in genotypically diverse pediatric iPSC-cardiomyocytes to mirror variant correction

Pathogenic variants in MYH7 and MYBPC3 account for the majority of hypertrophic cardiomyopathy (HCM). Targeted drugs like myosin ATPase inhibitors have not been evaluated in children. We generate patient and variant-corrected iPSC-cardiomyocytes (CMs) from pediatric HCM patients harboring single variants in MYH7 (V606M; R453C), MYBPC3 (G148R) or digenic variants (MYBPC3 P955fs, TNNI3 A157V). We also generate CMs harboring MYBPC3 mono- and biallelic variants using CRISPR editing of a healthy control. Compared with isogenic and healthy controls, variant-positive CMs show sarcomere disorganization, higher contractility, calcium transients, and ATPase activity. However, only MYH7 and biallelic MYBPC3 variant-positive CMs show stronger myosin-actin binding. Targeted myosin ATPase inhibitors show complete rescue of the phenotype in variant-positive CMs and in cardiac Biowires to mirror isogenic controls. The response is superior to verapamil or metoprolol. Myosin inhibitors can be effective in genotypically diverse HCM highlighting the need for myosin inhibitor drug trials in pediatric HCM.

Esophago-gastric junction findings on high resolution impedance manometry in children with esophageal atresia

OBJECTIVES

Using high resolution impedance manometry (HRIM), this study characterized the esophago-gastric junction (EGJ) dynamics in children with esophageal atresia (EA).

METHOD

Esophageal HRIM was performed in patients with EA aged less than 18 years. Objective motility patterns were analyzed, and EGJ data reported. Controls were pediatric patients without EA undergoing investigations for consideration of fundoplication surgery.

RESULTS

Seventy-five patients (M:F = 43:32, median age 1 year 3 months [3 months-17 years 4 months]) completed 133 HRIM studies. The majority (64/75, 85.3%) had EA with distal tracheo-esophageal fistula. Compared with controls, liquid swallows were poorer in patients with EA, as evident by significant differences in distension pressure emptying and bolus flow time (BFT). The integrated relaxation pressure for thin liquid swallows was significantly different between EA types, as well as when comparing patients with EA with and without previous esophageal dilatations. The BFT for solid swallows was significantly different when compared with EA types.

CONCLUSIONS

We have utilized HRIM in patients with EA to demonstrate abnormalities in their long-term EGJ function. These abnormalities correlate with poorer esophageal compliance and reduced esophageal peristalsis across the EGJ. Understanding the EGJ function in patients with EA will allow us to tailor long-term management to specific patients.

Decreased Posterior Tibial Slope and Its Association With Pediatric Posterior Cruciate Ligament Injury

BACKGROUND

Recent adult studies have demonstrated that decreased posterior tibial slope angle (PTSA) may be a risk factor for posterior cruciate ligament (PCL) injury. However, there is no study investigating this phenomenon in a pediatric population. Understanding risk factors for PCL injuries among a pediatric population is important given the recent rise in athletic competition/specialization and sports-related injuries.

HYPOTHESIS/PURPOSE

The purpose of this study was to compare PTSA between pediatric patients sustaining a primary PCL tear compared with age- and sex-matched controls. It was hypothesized that pediatric patients sustaining a PCL tear would have a decreased PTSA compared with controls, with decreased PTSA being associated with higher odds of PCL injury.

STUDY DESIGN

Cohort study; Level of evidence, 3.

METHODS

The records of all patients sustaining a PCL injury between 2006 and 2021 at a level 1 pediatric trauma center were reviewed. Patients aged ≤18 years with magnetic resonance imaging-confirmed PCL tear were included. Excluded were patients with concomitant anterior cruciate ligament tears, previous PCL reconstruction, or previous coronal plane realignment. A control cohort, with their ligament shown as intact on magnetic resonance imaging scans, was matched based on age and sex. PTSA was measured on lateral radiographs of the injured knee or tibia. The mean PTSA was compared between cohorts, and odds ratios were calculated based on the normal slope range (7°-10°) described in the literature, an upper range (>10°), and a lower range (<7°). Inter- and intrarater reliability were determined via calculation of an intraclass correlation coefficient.

RESULTS

Of the 98 patients who sustained a PCL injury in this study period, 59 (60%) met inclusion criteria, and 59 healthy knee controls were matched. There were no differences between the cohorts for age (P = .90), sex (P > .99), or body mass index (P = .74). The PCL cohort had a lower mean ± SD PTSA compared with the control group (5.9°± 2.7° vs 7.3°± 4.3°; P = .03). PTSA <7° was associated with a 2.8 (95% CI, 1.3-6.0; P = .01) times risk of PCL tear. Conversely, PTSA >10° was associated with a 0.27 (95% CI, 0.09-0.81; P = .02) times risk of PCL tear. These PTSA measurements demonstrated acceptable intrarater and interrater reliability.

CONCLUSION

PTSA <7° was associated with an increased odds of PCL injury, whereas a slope >10° was associated with a decreased odds of PCL injury in a pediatric population. These findings corroborate similar outcomes in adult studies; however, further studies are needed to elucidate PTSA as a risk factor for PCL injury.

Syndecan-1 Level, a Marker of Endothelial Glycocalyx Degradation, Is Associated With Fetal Exposure to Chorioamnionitis and Is a Potential Biomarker for Early-Onset Neonatal Sepsis

The goal of this investigation was to identify the association between Syndecan-1 (S1) serum levels in preterm newborns exposed to chorioamnionitis (CA) in utero and the potential of S1 as a biomarker of early-onset neonatal sepsis. A cohort of preterm newborns born <33 weeks gestational age was recruited. Within 48 hours of birth, 0.5 mL of blood was drawn to obtain S1 levels, measured via ELISA. Placentas were examined and classified as having (1) no CA, (2) CA without umbilical cord involvement, or (3) CA with inflammation of the umbilical cord (funisitis). S1 levels were compared between preterm newborns without exposure to CA verus newborns with exposure to CA (including with and without funisitis). Preterm newborns exposed to CA were found to have significantly elevated S1 levels compared to those unexposed. Although S1 levels could not differentiate fetal exposure to CA from exposure to CA with funisitis, the combined CA groups had significantly higher S1 levels compared to those not exposed to CA. S1 level has the potential to become a clinically useful biomarker that could assist in the management of mothers and preterm newborns with CA and funisitis. Furthermore, S1 level could aid in the diagnosis and treatment of early-onset neonatal sepsis.

Future Fertility Among Pediatric Cancer Patients: Experiences and Perspectives of Health Workers in a Low-Resource Setting

Purpose:Although fertility preservation for patients with childhood and adolescent cancer is considered standard of care in the high-resource settings, it is rarely offered in low-resource settings. This study explores the experiences and perspectives of oncology health care professionals in Uganda to identify contextual barriers and facilitators to addressing oncofertility in low-resource settings. Methods: Using ground theory, we conducted in-depth face-to-face interviews of health care professionals managing pediatric patients at the Uganda Cancer Institute (UCI). Using a systematic, semi-structured interview guide, participants were asked open-ended questions about their understanding of fertility preservation and their perspectives on implementing this care at their institution. Although all the eligible health care providers were interviewed, interview transcripts were uploaded into NVivo version 12 and openly coded as per theoretical requirements. Codes were refined into categories and later into structured themes. Results: Twelve health care professionals were interviewed. Most participants identified as female (n = 9). Their role in the medical team varied from nurses (n = 6), medical officers (n = 3), pediatric oncologists (n = 2), and pediatric oncology fellow (n = 1). Six themes were noted as follows: (1) importance of information, (2) importance of future fertility, (3) inadequate consideration to future fertility, (4) communication barriers, (5) inadequate knowledge, and (6) resource barriers. Conclusion: Although health care providers at the UCI face contextual barriers to addressing future fertility among patients with pediatric cancer, they value preserving fertility in this population. Future initiatives that aim to introduce oncofertility care in low-resource settings should prioritize educating providers and building capacity to meet the oncofertility needs in this setting.

Original Research: Clinical Significance of a Unique Pediatric EEG Configuration: Bi-Frontal Spikes With Simultaneous Bi-Occipital Positivity

Introduction: Frontal-predominant epileptiform discharges (EDs) include generalized spike-wave (GSW) and frontal spikes (FS). However, negative bi-frontal ED with simultaneous occipital positivity (BFOD) are rare, leading to questions regarding physiological generators. Methods: To determine the clinical significance of BFOD, electroclinical features of children with BFOD (n = 40) were compared to control patients with GSW (n = 102) and FS (n = 100). Results: Results are presented in the following order: BFOD, GSW, and FS. Epilepsy was prevalent among the groups: 95.0%, 90.2%, and 77.0%, respectively. The median age of seizure-onset did not significantly differ between groups: 3.00, 4.00, and 2.25 years, respectively. Regarding EEG background features, the BFOD group had more disorganized sleep architecture than other groups, P < .005. There was a significant difference in the proportion of developmental delay (DD) between the groups (P < .005). BFOD had much higher odds of DD compared to GSW and FS groups: odds ratio (OR) (confidence interval [CI]) 19.44 [5.64, 64.05] and 3.98 [1.16, 13.34]. Furthermore, BFOD had much higher odds of severe DD compared to GSW and FS groups: 9.60 [2.75, 33.45] and 2.73 [1.03, 7.27]. A Gross Motor Function Classification System (GMFCS) score of  ≥ 4 was more prevalent in BFOD (22.5%), than GSW (0%) and FS groups (9%). On neuroimaging, BFOD had more structural (P < .005) and multilobar structural (P < .05) abnormalities than control groups. Conclusion: Children with BFOD had particularly severe significant DD, considerable motor deficit (GMFCS ≥ 4), and brain structural abnormalities, often multilobar. This suggests BFOD is a marker of severe underlying brain dysfunction and not benign when encountered on routine EEG review.

Suspension Microesophagoscopy for Endoscopic Suture Closure of Pediatric Tracheoesophageal Fistula

A 15-year-old male with previous open tracheoesophageal fistula (TEF) repair presented with a large, short recurrent TEF. The TEF was denuded with cautery on the tracheal side and the patient was intubated with a cuffed endotracheal tube. Suspension microesophagoscopy allowed excellent exposure of the TEF from the esophageal side, which was cauterized. Four sutures were placed endoscopically from the esophageal side, and the TEF remained closed 6 months postoperatively. Laryngoscope, 2024.
