Introduction. Arboviruses, such as dengue and chikungunya, have caused multiple epidemics in the Americas. They are transmitted through mosquito bites; Aedes aegypti is their main vector. As of January 2023, coinciding with the fourth dengue outbreak in Argentina, a new dengue outbreak was observed in the Americas, coincident with the presence of chikungunya. We considered it essential to describe the demographic, epidemiological, clinical, and evolutionary characteristics of dengue/chikungunya patients seen in a tertiary pediatric hospital in the Autonomous City of Buenos Aires in 2023. Population and methods. Descriptive, observational, retrospective cohort study. Includes children of 0 to 16 years with compatible symptomatology and positive PCR or IgM for dengue or chikungunya from February 1, 2023, through May 31, 2023. Results. A total of 168 patients were identified, with a median age of 138 months (IQR: 107-164). The diagnosis of dengue was confirmed in 140 and of chikungunya in 28. Ninety-eight percent were autochthonous cases. In 85% of the cases, PCR was used to make the virological diagnosis of dengue, and in the remaining 15%, IgM was used. PCR diagnosed chikungunya in 61% of cases. Patients with dengue fever had a longer duration of fever, abdominal pain, headache, myalgias, and retroocular pain. Exanthema and arthralgias were associated with chikungunya. Conclusions. The epidemiology of mosquito-borne diseases is dynamic and is related to what happens in the rest of the countries of South America; knowledge of it is essential to predict the etiological risk and prevalence., (Sociedad Argentina de Pediatría.)

Background: Paracetamol and ibuprofen are the most commonly used drugs for pain treatment in children and their combination has shown improved analgesic effect compared to treatment with either drug alone. Current literature lacks specific guidelines regarding the settings in which this combination should be adopted., Methods: The survey, conducted with Delphi methodology, involved 75 hospital and outpatient pediatricians with clinical experience in the management of pain in children. Pediatricians involved were asked to validate or not the results of the previous NominalGroup Tecnique (NGT) consensus and thus specify the optimal clinical settings in which the paracetamol/ibuprofen fixed-dose combination could be adopted., Results: The results confirm the importance of the fixed-dose paracetamol and ibuprofen combination for the control of mild-to-moderate acute pain in children. Particularly, this association seems to be appropriate in case of headache, earache, odontalgia and musculoskeletal pain, and in specific settings such as post-operative and post-procedural pain. The broadening of the panel brought to slight variations in clinical management practices between hospital and outpatient specialists. Nonetheless, overall consensus supports the notion that the fixed dose combination is more efficacious than monotherapies and it is well tolerated. Moreover, experts unanimously agree on the usefulness of the combination for caregivers, leading to improved adherence and effectiveness., Conclusions: Both the NGT consensus and the broader Delphi consensus confirm the usefulness of the paracetamol-ibuprofen fixed-dose combination in pediatric pain. This is attributed to its superior effectiveness compared to monotherapies, a good tolerability profile, and improved compliance and ease of use. Some pain settings related to chronic, inflammatory and rheumatological pathologies remain to be investigated to evaluate the use of this combination., (© 2024. The Author(s).)

Molecular diagnosis for pediatric epilepsy patients can impact treatment and health supervision recommendations. However, there is little known about factors affecting the time to receive a diagnosis. Our objective was to characterize factors affecting the time from first seizure to molecular diagnosis in children with epilepsy. A retrospective, population-based review was used to analyze data from pediatric patients with a genetic etiology for epilepsy over a 5 year period. A subgroup of patients with seizure onset after 2016 was evaluated for recent trends. We identified 119 patients in the main cohort and 62 in a more recent (contemporaneous) subgroup. Sex, race, and ethnicity were not significantly associated with time to molecular diagnosis. A greater number of hospitalizations was associated with a shorter time to diagnosis (p < 0.001). Developmental delay was associated with a longer time to diagnosis (p = 0.002). We found no association for time to diagnosis with a diagnosis of autism, utilization of free genetic testing, or epilepsy type. In the recent subgroup analysis, commercial insurance was associated with decreased time to diagnosis (p = 0.02). Developmental delay, public insurance, or patients in the outpatient setting had longer times to molecular diagnosis. These findings suggest that there may be opportunities to implement interventions aimed at accelerating the provision of genetic testing in pediatric epilepsy. PLAIN LANGUAGE SUMMARY: Genetic diagnosis for pediatric epilepsy patients can impact treatment and care. This study looked at factors that affect how long it takes a pediatric epilepsy patient to receive a genetic diagnosis. We found that sex, race and ethnicity, epilepsy type, and whether the patient had autism did not affect how long it took the patient to receive a diagnosis. However, we found that patients with developmental delay, fewer hospitalizations, and public insurance took a longer time to receive a diagnosis. Our findings suggest potential strategies for reducing the time to receive a genetic diagnosis., (© 2024 The Author(s).

Background: Annually, about 4000 US children undergo a tracheostomy procedure to provide a functional, safe airway. In the hospital, qualified staff monitor and address problems, but post-discharge this responsibility shifts entirely to caregivers. The stress and constant demands of caregiving for a child with a tracheostomy with or without ventilator negatively affect caregivers. The aims of the study are to relieve the burden and stress experienced by caregivers at home, improve safety and outcomes for children post-discharge, and identify facilitators and barriers to implementation of comprehensive pediatric discharge programs., Methods: The Boosting REsources and cAregiver empowerment for Tracheostomy care at HomE (BREATHE Study) is a pragmatic two-arm, randomized trial with six sites across the US. Caregivers of a child with a tracheostomy are randomized to comparator ("Trach Me Home") or intervention ("Trach Plus"). The Comparator arm is the current gold standard focusing on caregiver education, technical skill building, and case management. The Intervention arm contains all elements of the Comparator plus educational resources, social support and communication with the outpatient pediatrician. Caregivers will complete three surveys: baseline (pre-discharge), 4-week and 6-month post-discharge. Outpatient pediatricians will complete a survey to assess self-confidence in caring for a child with tracheostomy and satisfaction with discharge communication. Interviews with clinicians and staff will identify facilitators and barriers to implementation. The study will examine whether the Intervention arm leads to lower caregiver burden, lower readmission rates and higher pediatrician satisfaction than Comparator arm., Discussion: The BREATHE Study will advance our understanding of how hospitals can support caregivers with a child with a tracheostomy as they resume life, work, and family activities after discharge., Trial Registration: Registered on clinicaltrials.gov (NCT06283953). February 28, 2024., (© 2024.

Pathogenic variants of WD repeat domain 45 ( WDR45 ) cause neurodegeneration with brain iron accumulation 5 (NBIA5), which is characterised by progressive neurological regression and brain iron accumulation in adulthood. Early diagnosis of NBIA5 patients is difficult because they often show only a non-specific developmental delay in childhood, but it is essential for lifelong medical management. We investigated 32 females with developmental delays for coding variants of WDR45 using Sanger sequencing. Whole-genome sequencing (WGS) and X chromosome inactivation (XCI) analysis were also performed. We identified two disease-causing variants, one of which was a novel stop-loss variant, c.1051delG p.(Val351CysfsTer60), in a female with severe developmental delay from early infancy with epileptic spasms. The XCI analysis (which we originally developed) suggested a random pattern in white blood cells. WGS did not reveal any other pathogenic variants, including those in two iron transporter genes. Together with our previous findings in the WGS study, WDR45 variants accounted for 12% (6/51) of the females with developmental delay, suggesting that WDR45 is a major gene in females with developmental delay. Pathogenic variants of WDR45 result in various phenotypes that do not necessarily correlate with variant types or XCI skewing patterns., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Background: Over the last 20 years, pediatric hypertension (pHTN) prevalence in Western society has risen from 3.5 to 9% due to childhood overweight, obesity, and secondary kidney and cardiological conditions. Few studies have assessed commonly used antihypertensive medication lisinopril's (ACE-inhibitor) long-term efficacy and the long-term value of renin-angiotensin-aldosterone system (RAAS) biomarkers., Methods: This is a retrospective cohort study at Ghent University Hospital, Belgium, with 106 young patients (1-18 years) treated with lisinopril due to hypertension (HTN) and chronic kidney disease (CKD) assessed for treatment outcomes against clinical benchmarks over 10 years., Results: Lisinopril was mainly initiated for secondary hypertension or nephroprotection (89%) due to kidney causes. A starting dose across groups was lower than 0.07 mg/kg for 48% (n = 50). HTN patients without CKD achieved systolic blood pressure below the 95th percentile within 2 years, but efficacy declined after 2.5 years. CKD patients maintained a steady response, reaching systolic targets by 40 months and showing improved diastolic control over 70 months. Proteinuria reduction had a median urine protein creatinine ratio (UPCR) to 0.57 g/g at 6 months, with a reappearance of UPCR 2 g/g creatinine after 40 months. Aldosterone breakthrough occurred from 6 months onward in all groups. Over 70 months, aldosterone and aldosterone-renin-ratio (ARR) progression significantly differ between children with and without normal kidney function., Conclusions: Treatment efficacy for systolic blood pressure in hypertensive patients with abnormal kidney function diminishes after 2.5 years and for proteinuria in children after 3 years, highlighting the need for dosage recalibration according to guidelines and/or the need for alternative treatments., (© 2024.

Background: Combining patient-generated health data and digital health platforms may improve patient experience and population health, mitigate rising health care costs, reduce clinician burnout, and enable health equity. However, lack of trust may be a notable barrier to the data-sharing required by such platforms. Understanding sociodemographic, health, and personal characteristics will enable developers and implementers of such technologies to consider these in their technical design requirements., Objective: This study aims to understand relationships between sociodemographic characteristics of caregivers of children or adolescents and trust in and willingness to use digital platforms to store and share personal health information for clinical care and research., Methods: This study used a mixed methods approach, including surveys of caregivers of youth aged <18 years living in Canada or the United States and youth aged 16 to 17 years living in Canada, as well as web-based bulletin board discussions to further explore topics of trust in data sharing. Sociodemographic and survey data were tabulated and explored using proportional odds ordinal regression models. Comments from web-based group discussions were analyzed thematically using a coding approach to identify issues important to the participants., Results: Survey data from 1128 caregivers (female participants: n=549, 48.7%; 36-50 years old: n=660, 58.5%; Canadian: n=603, 53.5%; urban population: n=494, 43.8%) were collected, of which 685 (60.7%) completed all questions. Data from 173 youth (female participants: n=73, 42.2%; urban population: n=94, 54.3%) were collected, of which 129 (74.6%) completed all questions, and data were available for analysis. Furthermore, among 40 participants, 23 (58%) caregivers contributed to the web-based discussion boards. Related to trust, living in a rural area (vs urban; odds ratio [OR] 0.66, 95% CI 0.46-0.95) resulted in lower concern for data privacy and security, while having an undergraduate (OR 1.82, 95% CI 1.30-2.55) or graduate degree (vs secondary or trade school; OR 2.50, 95% CI 1.68-3.73) resulted in higher levels of concern. Living with a chronic disease (OR 1.81, 95% CI 1.35-2.44) increased levels of concern regarding data privacy and security. Interestingly, those with chronic disease were more willing to use digital platforms for clinical care and share personal health information for not-for-profit research. Caregivers were most concerned about data breaches involving data from their children but also highlighted that digital platforms would allow for better coordination of care for their children., Conclusions: Our research confirms the willingness of caregivers and youth to use digital platforms for both clinical care delivery and research and suggests that the value of a digital platform may outweigh the risks of its use. Engagement of end users in co-designing such platforms has the potential to enhance digital trust. However, digital trust varies across sociodemographic groups; therefore, diverse end user engagement is necessary when designing digital applications., (©Eric Chow, Alice Virani, Susan Pinkney, Fatema S Abdulhussein, Tibor van Rooij, Matthias Görges, Wyeth Wasserman, Jeffrey Bone, Holly Longstaff, Shazhan Amed.

Background: : Acute bronchiolitis is a common cause of hospitalization during infancy that carries significant morbidity and mortality rates., Purpose: : This study compared the efficacy of different treatment modalities for infants with bronchiolitis in terms of hospital stay and clinical severity scores., Methods: : The PubMed database was searched for re- levant studies. Eligibility criteria included double-blind randomized controlled trial design, assessment of the effect of treatment on bronchiolitis in infants under 2 years of age, and publication in English from inception through July 31, 2020. The primary efficacy outcome was the length of hospital stay, while the secondary outcome was the clinical severity score. The standardized treatment effect and standard error of the effect size were calculated., Results: : We identified 45 randomized controlled trials of 24 pairwise comparisons. These 45 trials included 5,061 participants and investigated 13 types of interventions (12 active, 1 placebo). Inhalation therapy with epinephrine (standard mean difference [SMD], -0.41; 95% confidence interval [CI], -0.8 to -0.03) and hypertonic saline (SMD, -0.29; 95% CI, -0.55 to -0.03) reduced the length of hospital stay compared with normal saline. Hypertonic saline was the most effective at improving the clinical severity score (SMD, -0.52; 95% CI, -0.95 to -0.10)., Conclusion: : Inhalation therapy with epinephrine and hypertonic saline reduced the length of hospital stay and the clinical severity of bronchiolitis among infants under 2 years of age.

Background: Cardiovascular dysfunction is a significant factor contributing to weaning failure in mechanically ventilated children. Understanding the cardiopulmonary pathophysiological changes that occur during weaning is a prerequisite for the early recognition of weaning failure of cardiovascular origin. This study aimed to assess the effect of weaning trials on central hemodynamics and to identify the indices predictive of cardiac-related weaning failure., Methods: This prospective observational study was conducted in the Pediatric Intensive Care Unit (PICU) and included mechanically ventilated patients aged between 2 and 30 months who were on minimal ventilatory settings and ready for weaning. Patients who were hemodynamically unstable, diagnosed with neuromuscular diseases, or diagnosed with cardiac diseases were excluded. Hemodynamic parameters were evaluated during weaning from ventilation via echocardiography and noninvasive cardiometry during pressure support (PS) ventilation and at the end of the spontaneous breathing trial (SBT)., Results: The study included 50 patients, comprising 30 males (60%) and 20 females (40%) with ages ranging from 2 to 30 months. Echocardiography revealed a significant increase in the cardiac index (CI), tricuspid annular plane systolic excursion (TAPSE), and the E/A ratio at the end of SBT. Moreover, right ventricular systolic pressure (RVSP) significantly decreased. Noninvasive cardiometry revealed a significant increase in the index of contractility (ICON) and CI at the end of SBT (p-value = 0.023 and < 0.001, respectively). Of the 12 (25%) patients who failed their first extubation trial, they exhibited a significantly lower CI and TAPSE (p values = 0.001 and 0.001, respectively)., Conclusion: This study identified that weaning from mechanical ventilation in children is associated with hemodynamic changes, which can impact weaning success and reveal potential ventricular dysfunction. Bedside echocardiography was found to detect cardiac dysfunctions during weaning, and noninvasive cardiometry was considered a reliable tool that supports echocardiography for detecting changing trends in CI in PICUs. However, accurate values should be confirmed by echocardiography., (© 2024. The Author(s).)

Background: Acute pancreatitis (AP) increases the risk of diabetes mellitus (DM). Our aim was to identify clinical, laboratory and imaging predictors of preDM/DM in youth post index AP., Methods: This was a prospective cohort study of patients ≤21 years-old with an index admission for AP and follow up at 3 and/or 12 months. Clinical laboratory values, imaging findings, admission course, and plasma chemokine and cytokine measures collected at index admission were tested for association with preDM/DM development. A multivariable regression model was used to predict preDM/DM., Results: Among 187 enrolled participants, 137 (73 %) and 144 (77 %) underwent DM screening at 3 and 12 months respectively, and 137 (73 %) had imaging available. PreDM/DM occurred in 22/137 (16 %; preDM n = 21, DM n = 1) at 3 months and 23/144 (16 %; preDM n = 18, DM n = 5) participants at 12 months. Univariate associations with preDM/DM at 12 months included: severe AP (SAP) (52 % preDM/DM vs. 17 % no DM; p = 0.0008), median [IQR] IL-6 (910 pg/ml [618-3438] vs. 196 pg/ml [71-480], p < 0.05) and CRP (4.16 mg/L [1.67-10.7] vs. 1.55 mg/L [0.4-3.68], p = 0.1) at time of AP attack. The optimal multivariable model to predict preDM/DM included with clinical variables was severe acute pancreatitis (SAP), c reactive protein (CRP), interleukin-6 (IL-6), and age [AUC = 0.80; (0.70, 0.88)]. Including imaging markers, the ideal model included SAP, CRP, IL-6, subcutaneous fat area, age and presence of autoimmune disease with an AUC [0.82 (0.71, 0.90)]., Conclusions: Development of preDM/DM following an index AP episode can be predicted by baseline AP severity, baseline CRP, IL-6 levels, and subcutaneous fat area., Competing Interests: Conflicts of interest G Ginzburg has no declarations of interest.

Objective: To examine the cost-effectiveness of hypoglossal nerve stimulation (HGNS) implantation at an early age in simulated pediatric cohorts with Down Syndrome (DS) and severe obstructive sleep apnea (OSA)., Study Design: Cost-utility analysis., Setting: Hypothetical cohort., Methods: A Markov model simulated 3 pediatric cohorts with DS and OSA beginning at age 4 years until 21 years. Cohorts received HGNS implants in early childhood, late childhood, or adulthood at age 4, 13 (current FDA-approved age), or 18 years, respectively. Input model parameters were obtained from the literature and our institution. Outcomes were measured with an incremental cost-effectiveness ratio (ICER), measured in dollars per quality-adjusted life-year (QALY). Deterministic 1-way sensitivity analyses were conducted to evaluate the effects of parameter uncertainty., Results: Results (total costs; total QALYs) across the time horizon were determined for each cohort: early implantation ($83,300.35; 15.79), late ($48,319.09; 14.98), and adult ($38,721.07; 14.55). ICERs were $48,892.47 per QALY for early vs late implantation, $43,471.15 per QALY for early vs adult implantation, and $30,959.58 per QALY for late vs adult implantation. All ICERs were below a willingness-to-pay threshold of $50,000 per QALY. Varying the discount rate and utility expectedly varied the ICERs and cost-effectiveness. Threshold analysis showed early implantation to be cost-effective for a HGNS implantation cost up to $62,230 compared to late implantation., Conclusion: The current study suggests HGNS is a cost-effective treatment strategy for pediatric patients with DS and severe OSA. Our findings also suggest cost-effectiveness at ages younger than 13, the current age of FDA approval., (© 2024 American Academy of Otolaryngology–Head and Neck Surgery Foundation.)

Objective: Brain somatic variants in SLC35A2 were recently identified as a genetic marker for mild malformations of cortical development with oligodendroglial hyperplasia in epilepsy (MOGHE). The role of SLC35A2 in cortical development and the contributions of abnormal neurons and oligodendrocytes to seizure activity in MOGHE remain largely unexplored., Methods: Here, we generated a novel Slc35a2 floxed allele, which we used to develop two Slc35a2 conditional knockout mouse lines targeting (1) the Emx1 dorsal telencephalic lineage (excitatory neurons and glia) and (2) the Olig2 lineage (oligodendrocytes). We examined brain structure, behavior, and seizure activity., Results: Knockout of Slc35a2 from the Emx1 lineage, which targets both cortical neurons and oligodendrocytes, resulted in early lethality and caused abnormal cortical development, increased oligodendroglial cell density, early onset seizures, and developmental delays akin to what is observed in patients with MOGHE. By tracing neuronal development with 5-Ethynyl-2'-deoxyuridine (EdU) birthdating experiments, we found that Slc35a2 deficiency disrupts corticogenesis by delaying radial migration of neurons from the subventricular zone. To discern the contributions of oligodendrocytes to these phenotypes, we knocked out Slc35a2 from the Olig2 lineage. This recapitulated the increased oligodendroglial cell density and resulted in abnormal electroencephalographic activity, but without a clear seizure phenotype, suggesting Slc35a2 deficiency in neurons is required for epileptogenesis., Significance: This study presents two novel Slc35a2 conditional knockout mouse models and characterizes the effects on brain development, behavior, and epileptogenesis. Together, these results demonstrate a direct causal role for SLC35A2 in MOGHE-like phenotypes, including a critical role in neuronal migration during brain development, and identify neurons as key contributors to SLC35A2-related epileptogenesis., (© 2024 The Author(s).

Vaccination plays a crucial role in preventing and controlling SARS-CoV-2 infections as well as their associated adverse outcomes. But there is a notable lack of research on the effectiveness of COVID-19 vaccination in children, particularly those young preterm-born children, who are more vulnerable to severe outcomes from SARS-CoV-2 infection. We aimed to determine the effect of vaccination with inactivated vaccines BBIBP-CorV and CoronaVac on symptomatic COVID-19 infection and related symptoms in preterm-born children aged 3-7 years after relaxation of the COVID-19 prevention and control measures in December 2022 in China. We performed a retrospective cohort study involving 242 preterm-born children aged 3-7 years and the data were collected in March 2023. Logistic regression models and modified Poisson regression models combined with entropy balancing were used to explore the associations of vaccination against SARS-CoV-2 with symptomatic COVID-19, specific symptoms, and persistent symptoms one month after recovery from COVID-19. Of the 242 recruited preterm-born children, 156 (64.5%) were vaccinated with inactivated vaccines BBIBP-CorV and CoronaVac. After entropy balancing, the covariates were balanced between the vaccinated and the unvaccinated groups, with standardized mean difference < 0.001. Vaccination with the said SARS-CoV-2 vaccines lowered the risk of developing symptomatic COVID-19 in preterm-born children (risk ratio [RR] = 0.783; 95% confidence interval [CI]: (0.711, 0.861). Likewise, COVID-19 vaccination was associated with a decline in the risk of pneumonia (odds ratio [OR] = 0.318; 95% CI 0.110, 0.913), fever (RR = 0.710; 95% CI 0.635, 0.794), high fever (RR = 0.542; 95% CI 0.297, 0.988), sore throat (OR = 0.304; 95% CI 0.139, 0.664), and persistent symptoms (RR = 0.425; 95% CI 0.182, 0.993). Immunization with inactivated vaccines BBIBP-CorV and CoronaVac provides protection against symptomatic COVID-19 for preterm-born children 3-7 years., (© 2024. The Author(s).)

Background: Preventive screenings in children encourage maintenance of optimal cardiovascular health, but gaps may exist between recommendations and clinical practice. We evaluated adherence to pediatric guidelines for universal age-based and risk-based screening for body mass index, blood pressure, lipids, and blood glucose., Methods and Results: We used 2010 to 2018 ambulatory visit data from children aged 2 to 12 years within CAPRICORN (Chicago Area Patient-Centered Outcomes Research Network), an electronic health record network in Chicago. This study included 87 549 children who attended 197 559 well-child encounters. Across all encounters, children were 51.5% male and mean (SD) age 6.4 (3.3) years. For each child who attended a well-child visit and met age and/or risk-based criteria, receipt of body mass index, blood pressure, lipids, and/or hemoglobin A1c or fasting blood glucose measurements were assessed. We used generalized estimating equations to calculate proportion adherence for each metric overall and stratified by age, sex, race and ethnicity, and insurance status. Universal age-based screening prevalence (95% CI) per 100 eligible visits was 77.1 (76.8-77.3) for body mass index, 33.4 (33.1-33.7) for blood pressure, and 9.6 (9.3-9.9) for lipids. Risk-based screening prevalence (95% CI) per 100 eligible visits was 13.9 (12.2-15.9) for blood pressure, 6.9 (6.4-7.5) for lipids, and 13.3 (12.6-14.1) for blood glucose., Conclusions: Early screening of cardiovascular health risk factors could lead to earlier interventions, which could alter cardiovascular health trajectories across the lifetime. Low-to-moderate levels of adherence to universal age-based and risk-based cardiovascular health screening highlight the gap between recommendations and clinical practice, emphasizing the need to understand and address barriers to screening in pediatric populations.

Acthar ® Gel (repository corticotropin injection; Mallinckrodt Pharmaceuticals, NJ, USA) is indicated for the treatment of myriad inflammatory disorders and is currently administered manually via a vial and syringe. The administration of Acthar via a single-dose prefilled injector (SelfJect™) is intended to simplify its subcutaneous (SC) delivery. The purpose of this review was to determine whether SelfJect is suitable for use in pediatric patients through a literature assessment of various factors, including skin depth, needle length and gauge, dosage, force required for injection, and potential harms. Infants and young children, who commonly have skin-to-muscle distances less than the minimum depth of SelfJect administration, may have risk of unintentional intramuscular (IM) injection; however, an inadvertent IM injection poses no additional risk to children because of the bioequivalence between SC and IM administration of Acthar. The needle gauge of SelfJect is acceptable for pediatric patients and aligns with the Centers for Disease Control and Prevention recommendations for SC injections. The dosage delivered by SelfJect is only appropriate for children over 2 years of age. Although adolescents would likely be able to achieve the minimum force required to remove the protective cap and deliver a full dose of Acthar with SelfJect, an adult (18 years of age and older) should administer SelfJect to pediatric patients. In addition to the commonly reported postmarketing adverse events (AEs) from Acthar administration (e.g., asthenic conditions, fluid retention, insomnia, headache and increased blood glucose), injection site-related AEs common to injection devices may occur with SelfJect use. The risk of needlestick injury from SelfJect is mitigated by a needle guard. In summary, this review of injection device considerations demonstrates that SelfJect is appropriate for use in the pediatric population.

Background: This study sought to estimate the overall cumulative incidence and odds of Hospital-acquired venous thromboembolism (VTE) among critically ill children with and without exposure to invasive ventilation. In doing so, we also aimed to describe the temporal relationship between invasive ventilation and hospital-acquired VTE development., Methods: We performed a retrospective cohort study using Virtual Pediatric Systems (VPS) data from 142 North American pediatric ICUs among children < 18 y of age from January 1, 2016-December 31, 2022. After exclusion criteria were applied, cohorts were identified by presence of invasive ventilation exposure. The primary outcome was cumulative incidence of hospital-acquired VTE, defined as limb/neck deep venous thrombosis or pulmonary embolism. Multivariate logistic regression was used to determine whether invasive ventilation was an independent risk factor for hospital-acquired VTE development., Results: Of 691,118 children studied, 86,922 (12.4%) underwent invasive ventilation. The cumulative incidence of hospital-acquired VTE for those who received invasive ventilation was 1.9% and 0.12% for those who did not ( P < .001). The median time to hospital-acquired VTE after endotracheal intubation was 6 (interquartile range 3-14) d. In multivariate models, invasive ventilation exposure and duration were each independently associated with development of hospital-acquired VTE (adjusted odds ratio 1.64 [95% CI 1.42-1.86], P < .001; and adjusted odds ratio 1.03 [95% CI 1.02-1.03], P < .001, respectively)., Conclusions: In this multi-center retrospective review from the VPS registry, invasive ventilation exposure and duration were independent risk factors for hospital-acquired VTE among critically ill children. Children undergoing invasive ventilation represent an important target population for risk-stratified thromboprophylaxis trials., Competing Interests: The authors have disclosed no conflicts of interest., (Copyright © 2024 by Daedalus Enterprises.)

Background: PEEP is a cornerstone treatment for children with pediatric ARDS. Unfortunately, its titration is often performed solely by evaluating oxygen saturation, which can lead to inadequate PEEP level settings and consequent adverse effects. This study aimed to assess the impact of increasing PEEP on hemodynamics, respiratory system mechanics, and oxygenation in children with ARDS., Methods: Children receiving mechanical ventilation and on pressure-controlled volume-guaranteed mode were prospectively assessed for inclusion. PEEP was sequentially changed to 5, 12, 10, 8 cm H 2 O, and again to 5 cm H 2 O. After 10 min at each PEEP level, hemodynamic, ventilatory, and oxygenation variables were collected., Results: A total of 31 subjects were included, with median age and weight of 6 months and 6.3 kg, respectively. The main reasons for pediatric ICU admission were respiratory failure caused by acute viral bronchiolitis (45%) and community-acquired pneumonia (32%). Most subjects had mild or moderate ARDS (45% and 42%, respectively), with a median (interquartile range) oxygenation index of 8.4 (5.8-12.7). Oxygen saturation improved significantly when PEEP was increased. However, although no significant changes in blood pressure were observed, the median cardiac index at PEEP of 12 cm H 2 O was significantly lower than that observed at any other PEEP level ( P = .001). Fourteen participants (45%) experienced a reduction in cardiac index of > 10% when PEEP was increased to 12 cm H 2 O. Also, the estimated oxygen delivery was significantly lower, at 12 cm H 2 O PEEP. Finally, respiratory system compliance significantly reduced when PEEP was increased. At a PEEP of 12 cm H 2 O, static compliance had a median reduction of 25% in relation to the initial assessment (PEEP of 5 cm H 2 O)., Conclusions: Although it may improve arterial oxygen saturation, inappropriately high PEEP levels may reduce cardiac output, oxygen delivery, and respiratory system compliance in pediatric subjects with ARDS with low potential for lung recruitability., Competing Interests: The authors have disclosed no conflicts of interest., (Copyright © 2024 by Daedalus Enterprises.)

Purpose: To determine the physical compatibility of 10% calcium chloride and 10% calcium gluconate in combination with injectable solutions, administered in the paediatric and adult intensive care unit setting during toxicological resuscitation involving calcium channel blockers and beta-blockers., Methods: Forty-eight combinations were prepared at room temperature, including the following products: calcium chloride, calcium gluconate, insulin, epinephrine, norepinephrine, highly concentrated dextrose solution, sodium chloride, Plasma-Lyte A and Ringer's lactate. A visual evaluation at times 0, 1, 4, 24, 48 and 72 hours and a particle count test with the LS-20 particle counter at times 0, 4, 24 and 72 hours were performed. The admixtures were considered incompatible if there was a precipitate, a colour change, turbidity, viscosity or a gas formation. The stability of calcium salts was also tested in empty IV bags and syringes by the particle count test., Results: All drug mixtures were found to be compatible by visual evaluation and using the particle counter based on United States Pharmacopoeia chapter 788 (USP<788>) specifications. Calcium salts were compatible with insulin and vasopressors in the tested combinations. The stability of 10% calcium salts in empty IV bags and polypropylene syringes was demonstrated for up to 48 hours at room temperature., Conclusion: All the combinations tested were physically compatible for up to 72 hours at room temperature. Clinical use of calcium salt infusions, at an undiluted concentration, in combination with these injectable solutions in a toxicological resuscitation context is considered clinically acceptable., Competing Interests: Competing interests: None declared., (© European Association of Hospital Pharmacists 2024.

Background: Antimicrobials are widely used in hospitals and are often associated with adverse drug reactions (ADRs). The objective of this study was to determine the incidence of ADRs caused by antimicrobials and classify them according to the type of reaction, the class of antimicrobials used, causality, severity and avoidability., Methods: A prospective cohort study was carried out with paediatric patients for 6 months. Causality was verified using the Naranjo and Liverpool algorithms, the severity was verified with the adapted scale of Hartwig and the avoidability was verified with the Liverpool Avoidability Assessment Tool., Results: A total of 303 patients were followed, and 18.2% (55/303) of them had one or more ADRs during the hospital stay. Just over half of the patients (28/55) had diarrhea. The most used antimicrobials were beta-lactams and second-generation cephalosporins. Suspicions were classified mainly as possible 78.6% (55/70) according to the Naranjo algorithm, and as probable 48.6% (34/70) according to the Liverpool algorithm. The antimicrobial most involved with ADRs was cefepime. The risk of manifesting ADR was greater with the use of some antimicrobials such as clindamycin (relative risk (RR) 3.0, CI 1.67 to 5.4), as well as with the increase in hospitalisation days (OR 1.022, CI 1.008 to 1.036) and in the number of antimicrobials prescribed (OR 1.649, CI 1.360 to 2.001)., Conclusion: ADRs were observed in approximately one-fifth of patients and were mostly gastrointestinal, moderate, unavoidable and with variable causality, depending on the algorithm used., Competing Interests: Competing interests: None declared., (© European Association of Hospital Pharmacists 2024.

Very preterm birth and treatment in neonatal intensive care cause stress early in life of the infant and may subsequently lead to psychological and behavioural traumas. Previous studies show positive outcomes of eye movement desensitisation and reprocessing (EMDR) therapy on trauma in children in general. This case report describes two girls that were born at very premature age (with birth weights of approximately 1000 g). They required intensive treatment in the neonatal intensive care. In early childhood, they presented with selective mutism (SM). We treated them with EMDR therapy because we hypothesised that trauma from the postnatal period had caused post-traumatic stress disorder. The EMDR therapy resulted in a long-lasting improvement in speech, social skills and communication. This is the first case report of development of SM in ex-premature infants that were treated with EMDR therapy in early childhood., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2024.

Background: Interstitial lung disease (ILD) is a serious complication in systemic juvenile idiopathic arthritis (SJIA). This study aimed to identify the clinical characteristics and prognosis of SJIA-ILD., Methods: A two-center retrospective cohort study was conducted on patients newly diagnosed with SJIA in China from October 2010 to December 2021. Clinical characteristics, laboratory parameters, outcomes, and relapse rates were compared between ILD and non-ILD groups., Results: A total of 176 children with SJIA were included, including 35 in ILD group and 141 in non-ILD group. The median age at onset of SJIA was 5.8 years (range 4.4-9.5) in patients with SJIA-ILD. It exhibited higher incidences of cervical spine (28.6%) and hip involvement (40.0%) in ILD group (P = 0.031 and P = 0.029, respectively). The incidence of macrophage activation syndrome (MAS) in ILD group reached up to 40%, significantly elevated than that in non-ILD group (P = 0.047). Children with ILD demonstrated a stronger inflammatory response and were more prone to developing lymphopenia (P = 0.009), requiring more combination therapy (P = 0.006) to control disease activity. 54.3% of patients received biologic therapies, with only three patient receiving biologics (one with IL-6 blockade, two with TNF inhibitor) prior to ILD onset and none receiving IL-1 blockade. The median follow-up duration was 6.0 years (range 3.9-9.5). The proportions of patients with SJIA-ILD achieving clinical inactive disease without glucocorticoids within 6 to 12 months of the treatment were significantly lower than control group (45.7% vs. 70.2%, P = 0.006). In ILD group, only 54.3% of patients achieved complete remission, and 17.1% were in a non-remission state, among whom two deaths from respiratory failure. There was no significant difference in disease relapse rates between the two groups (P > 0.05)., Conclusions: Patients with SJIA-ILD exhibited heightened inflammation, increased hip joint and cervical spine involvement, and were more susceptible to developing lymphopenia and MAS, suggesting a relatively poor prognosis. They required a prolonged time to control inflammation and more aggressive treatment strategies to achieve inactive status. The unsatisfactory rate of complete remission highlighted an urgent need for focused clinical strategies., (© 2024. The Author(s).)

Background: Tuberous Sclerosis complex (TSC) is a multisystemic neurocutaneous genetic condition with high rates of morbidity and mortality from subependymal giant cell astrocytoma (SEGA), renal angiomyolipoma, and renal cyst complications. Everolimus is an inhibitor for mTORC1 and is currently used to treat TSC for its main role in rapidly reducing SEGA volume and seizure burden, although mainly studied in the adult population. It has also been shown to stabilize estimated glomerular filtration rate and reduce renal angiomyolipoma size in the adult population., Case Presentation: This case report illustrates three pediatric patients placed on everolimus for SEGA and seizure control with incidental findings of the disappearance of or decreased burden of cystic kidney disease after everolimus therapy. In one patient, the cyst burden remained stable even after the cessation of everolimus while the SEGA resumed growth., Conclusions: This report demonstrates the utility of everolimus in not only renal angiomyolipomas but also cystic kidney disease particularly in pediatric patients with a promising role in preserving renal function and preventing long term sequelae such as hematuria and hemorrhage from larger renal cysts especially if used early on in disease course., (© 2024.

Background: Legal performance enhancing substance (PES) use is increasing in young athletes and may lead to banned PES use. This study examines legal PES use and consideration of banned PES use in young athletes with a season-ending injury (SEI) compared to young athletes with non-SEI/no previous injury., Hypothesis: Young athletes sustaining SEI or concussions have increased odds of reporting legal PES use and consideration of banned PES use compared with non-SEI or no injury., Study Design: Cross-sectional study., Level of Evidence: Level 4., Methods: Cross-sectional study from 2013 to 2020 of athletes aged 6 to 25 years., Results: No association was found between reporting legal PES use or consideration of banned PES use and young athletes with SEI or concussion compared with no injury/non-SEI. 14% of athletes reported legal PES use and 3% reported consideration of banned PES use. In adjusted analysis, athletes who were male (odds ratio [OR], 1.38; 95% CI, 1.16-1.73; P = 0.03), have history of depression (OR, 3.01; 95% CI, 1.26-7.18; P = 0.01), weight train (OR, 1.66; 95% CI, 1.04-2.65; P = 0.03), and believe that athletic ability is influenced by weight (OR, 1.75; 95% CI, 1.08-2.83; P = 0.02) had increased odds of reporting legal PES use. Older (OR, 1.18; 95% CI, 1.03-1.36; P = 0.02) and male (OR, 1.57; 95% CI, 1.02-1.81; P < 0.04) athletes had increased odds of consideration of banned PES use., Conclusion: This study found no increased odds of reported PES use in young athletes with sports-related injury or concussion regardless of injury type or severity. Factors associated with PES use were male sex, age, history of depression, weight training, and belief that weight affects athletic performance., Clinical Relevance: Risk factors associated with PES use in young athletes are essentially unknown. This study can inform pertinent clinical care, education, and policy implementation., Competing Interests: The authors report no potential conflicts of interest in the development and publication of this article.

The Response Assessment in Pediatric Neuro-Oncology (RAPNO) Working Group is an international, collaborative network of experts dedicated to pediatric central nervous system (CNS) tumors that was created in 2011. Since then, six RAPNO articles with imaging guidelines for response assessment in diverse pediatric tumor subgroups have been published, namely: 1) medulloblastomas and leptomeningeal seeding tumors (2018), 2) pediatric high-grade gliomas (2020), 3) pediatric low-grade gliomas (2020), 4) diffuse intrinsic pontine gliomas (2020), 5) pediatric intracranial ependymomas (2022) and 6) pediatric craniopharyngiomas (2023). The purpose of this article is to review all current available RAPNO criteria using a systematized and comparative approach centered on the role of neuroradiologists and supported by neuroimaging examples. Special emphasis will be placed on clarification of core concepts as well as practical adoption aspects of the RAPNO guidelines, namely how and when to image the brain and/or the spine; how to interpret the imaging findings; which other clinical, therapeutic and laboratory variables to consider; and finally how to apply the information to attribute the final appropriate response assessment classification., (© 2024.

Introduction. Dengue is a viral infection that may be asymptomatic or include severe manifestations. This study aims to describe the characteristics of a pediatric population during the epidemic outbreak in 2023. Population and methods. This cross-sectional study included patients with probable or confirmed dengue fever who were seen from March 13, 2023, to May 19, 2023, in a pediatric hospital in the Autonomous City of Buenos Aires. Results. A total of 112 patients were included. The median age was 12 years; 58% were male. Seventy-six percent of them came from the City of Buenos Aires. Twenty-five percent had cohabitants with symptoms compatible with a suspected case. The most frequent clinical manifestations were fever, headache, retro-ocular pain, myalgia, and arthralgia. The most frequent laboratory alterations were leukopenia (65%) and elevated transaminases (60%). Twenty-one percent (24/112) presented alarm signs and required hospitalization. Leukopenia, plateletopenia, and elevated transaminases were associated with the presence of alarm signs. RT-PCR was detected in fifty-three patients; serotype 2 was the most frequent. Twenty-one patients had positive NS1 tests, 18 patients had positive IgM, and 20 patients with clinical and epidemiological links were assumed to be probable dengue cases. There were no cases of severe dengue. Conclusion. Early clinical suspicion and recognition of laboratory parameters associated with alarm signs are essential for an adequate approach to the disease and early supportive treatment during dengue infection., (Sociedad Argentina de Pediatria.)

Objective: The aim of this study was to identify the relationship between preventative dental practices and cardiometabolic health in adolescents., Method and Materials: Analysis included children aged 13 to 17 years enrolled in the National Health and Nutrition Examination Survey (NHANES) from 2011 to 2018 who completed an Oral Health Examination and Questionnaire. Deferred dental care was defined as not having a dental visit in the past year. Financial barriers to seeking dental care (vs no financial barriers) were assessed among those with deferred dental care in the past year. Primary cardiometabolic outcomes included obesity, elevated blood pressure, and hypertensive blood pressure. Secondary outcomes included dyslipidemia, glucose intolerance, uric acid, glomerular hyperfiltration, and albuminuria. Regression models adjusted for age, sex, race/ethnicity, household income, food insecurity, health insurance status, household education, and body mass index z-score examined associations using complex survey design procedures., Results: Of 2,861 adolescents, 17.6% (SE 0.9%) did not receive dental care in the past year and 20.2% (SE 1.9%) had a financial barrier to accessing dental care. In adjusted regression models, adolescents with deferred dental care had higher odds of dyslipidemia (odds ratio [OR]= 1.51, 95% CI 1.07 to 2.11, P = .020). Having a financial barrier was associated with lower odds of dyslipidemia (OR = 0.35, 95% CI 0.14 to 0.89, P = .03). Financial barriers were associated with lower non-high-density lipoprotein cholesterol (b = -7.95, 95% CI -14.87 to -1.05, P = .03) and higher high-density lipoprotein cholesterol (b = 3.06, 95% CI 0.37 to 5.75, P = .03) in adjusted models. Deferred dental care and financial barriers were not associated with any other cardiometabolic parameters., Conclusion: In this nationally representative cohort of adolescents, there was an association between lack of preventative dental care and the cardiometabolic health marker of dyslipidemia. However, financial barriers to dental care were surprisingly associated with higher high-density lipoprotein cholesterol levels and lower odds of dyslipidemia.

Background and Purpose: This study aimed to assess the validity and reliability of the Dutch Eating Behavior Questionnaire for Children (DEBQ-C) among 6- to 8-year-old Black girls. Methods: Investigators of this cross-sectional online survey of 112 Black mother-daughter dyads used principal component analysis (PCA) to assess evidence of the DEBQ-C's construct validity. Pearson's product-moment correlations were also used to compare the DEBQ-C's subscale scores to an independent measure of eating behaviors. A comparison of the subscale scores between participants with favorable and unfavorable eating behaviors was used to evaluate discriminant validity. coefficient α examined the DEBQ-C's internal consistency reliability. Results: Principal component analysis established evidence of validity with three subscales. Significant correlations were found between the independent measure of eating behavior and the emotional ( r = -.25, p = .01) and external subscales ( r = -.31, p = .001). Participants increased emotional ( t = 2.53; df = 76; p = .007) and external ( t = 3.98; df = 99; p < .001) eating scores had unfavorable eating behavior scores. Conclusions: Psychometric results demonstrate questionable support for the construct validity of two of the DEBQ-C subscales (emotional and restrained eating) and the reliability of the DEBQ-C questionnaire among 6- to 8-year-old Black girls. The questionnaire's three subscales, emotional, external, and restrained eating, can be used to examine eating behaviors., (© Copyright 2024 Springer Publishing Company, LLC.)

Objective: The second year of undergraduate medical education is a critical phase transitioning from basic medical knowledge to specialized learning, requiring strong critical thinking abilities. Pediatric diseases, with their unique characteristics, demand active critical thinking from pediatricians. This study aims to investigate and analyze the critical thinking dispositions of second-year pediatric medical students, identify influencing factors, and propose recommendations for improving teaching methods., Methods: This cross-sectional study employed the Chinese version of the California Critical Thinking Disposition Inventory (CTDI-CV) and conducted an online survey among 240 second-year pediatric medical students at Chongqing Medical University, Chongqing, China. The study described the overall CTDI-CV scores and sub-dimension scores (mean ± standard deviation) and analyzed the distribution of critical thinking dispositions using t -tests and trend analysis., Results: A total of 229 students (95.4%) completed the survey, with 58.95% being female. The overall mean critical thinking score was 287.96 ± 39.09, and 139 students (60.70%) exhibited positive or highly positive critical thinking dispositions. Rural students scored lower than non-rural students (t = -2.773, P = 0.0069), while only children scored higher than non-only children (t = 2.659, P = 0.0086). Higher high school academic ranking was associated with higher scores (H = 23.85, P < 0.001). Students whose parents had a bachelor's degree or higher scored significantly better (t = 2.373, P = 0.0188). Interest in pediatrics was linked to higher scores (H = 15.36, P = 0.0015). Positive correlations were found between analyticity, inquisitiveness, and self-confidence (r ≥ 0.75)., Conclusion: Second-year pediatric medical students in China generally display strong critical thinking abilities. Factors such as family background, academic performance, parental education level, and interest in pediatrics significantly influence these abilities. Pediatric educators should account for these individual differences to better enhance critical thinking development in students and improve teaching strategies accordingly., Competing Interests: Li Long and Jing Li are co-responding authors for this study.

Paediatric cardiovascular diseases have been referred to as diseases of injustice as access to care is inequitable globally. For example, Africa only has 78 cardiac centres, with 22 located in Sub-Saharan Africa. Most of these centres rely on visiting surgical teams to provide clinical care. While visiting surgical teams provide essential care, building a sustainable and locally run cardiac workforce in Africa is critical to addressing these inequities in access to care. This paper considers the role of south-to-south partnerships in building sustainable surgical programmes using Rwanda's paediatric cardiac surgery programme as an example., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Mulibrey nanism (MN) is a extremely rare genetic condition first described in 1973, with around 150 cases reported worldwide. MN is characterised by growth delay and multiorgan manifestations, the most fatal being a combination restrictive-constrictive, perimyocardial heart disease that results in diastolic heart failure. We present a male toddler with MN who presented with recurrent episodes of hypoxia, feeding intolerance, and generalised swelling (anasarca) in the setting of subtle echocardiographic findings. A multidisciplinary and systematic diagnostic approach was used to determine the underlying aetiology. Invasive cardiac testing via right heart catheterisation revealed the final diagnosis of restrictive cardiomyopathy. Transplant decision-making was limited due to hepatic involvement. This case highlights the limitations of echocardiography in diagnosing restrictive cardiomyopathy, which has a preserved ejection fraction, as well the need for multidisciplinary involvement and a family-centred approach in treating patients with this rare condition., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2024.

Objective: The primary objective was to investigate temporal trends and between-practice variability of paediatric test use in primary care., Methods and Analysis: This was a descriptive study of population-based data from Clinical Practice Research Datalink Aurum primary care consultation records from 1 January 2007 to 31 December 2019. Children aged 0-15 who were registered to one of the eligible 1464 general practices and had a diagnostic test code in their clinical record were included. The primary outcome measures were (1) temporal changes in test rates measured by the average annual percent change, stratified by test type, gender, age group and deprivation level and (2) practice variability in test use, measured by the coefficient of variation., Results: 14 299 598 diagnostic tests were requested over 27.8 million child-years of observation for 2 542 101 children. Overall test use increased by 3.6%/year (95% CI 3.4 to 3.8%) from 399/1000 child-years to 608/1000 child-years, driven by increases in blood tests (8.0%/year, 95% CI 7.7 to 8.4), females aged 11-15 (4.0%/year, 95% CI 3.7 to 4.3), and children from the most socioeconomically deprived group (4.4% /year, 95% CI 4.1 to 4.8). Tests subject to the greatest temporal increases were faecal calprotectin, fractional exhaled nitric oxide and vitamin D. Tests classified as high-use and high-practice variability were iron studies, coeliac testing, vitamin B 12 , folate, and vitamin D., Conclusions: In this first nationwide study of paediatric test use in primary care, we observed significant temporal increases and practice variability in testing. This reflects inconsistency in practice and diagnosis rates and a scarcity of evidence-based guidance. Increased test use generates more clinical activity with significant resource implications but conversely may improve clinical outcomes. Future research should evaluate whether increased test use and variability are warranted by exploring test indications and test results and directly examine how increased test use impacts on quality of care., Competing Interests: Competing interests: This project was funded by a grant from the NIHR SPCR grant (Award 624).

Objective: The objective of this study is to evaluate three-dimensional vertical motion of the superior surface of the vocal folds in vivo in (a) typically developing children as a function of vocal frequency variations and (b) a child with vocal nodules., Methods: A custom developed laser endoscope coupled with high-speed videoendoscopy was used to obtain 3D parameters from 2 healthy children, one child with vocal nodules, and 23 vocally healthy adults (females = 11, males = 12). Parameters of amplitude (mm), maximum opening/closing velocity (mm/s), and mean opening/closing velocity (mm/s) were computed for the lateral and vertical vibratory motion along the anterior, middle, and posterior sections of the vocal folds were computed., Results: We provide for the first time, absolute measurements of vertical amplitude and maximum/ mean velocity during the opening and closing phases, in vivo in children. Overall, the vertical motion was larger in vocally normal children compared with the lateral motion, especially along the visible posterior section of the vocal folds and during low pitch phonation. The opening phase dynamics were consistently large along the posterior section in the child with vocal nodules., Conclusions: The study findings establish the feasibility of capturing 3D motion in a clinical setting and provide proof of concept for the application of the proposed 3D laser in the pediatric population. Future large sample size studies are needed to establish the diagnostic potential of examining the closing phase vertical motion to evaluate vibratory development in children with normal voice and investigating the opening phase vertical motion in children with nodules., Level of Evidence: N/A., (© 2024 The Author(s).

Background: We investigated the effectiveness of a novel, hunger-based outpatient tube weaning program for children with feeding-tube dependency., Methods: This interdisciplinary program induced hunger via rapid reduction in tube-fed calories, followed by 2 weeks of daily outpatient mealtime support and regular follow-up. Forty-one children (6.9 months to 12.8 years) participated in this retrospective cohort study., Results: Before the program, children received a median of 90.0% (interquartile range [IQR]: 75.0%-100%) of caloric intake via tube feeds. At the end of the 2-week program, children received 16.0% (IQR: 0.0%-30.0%) of caloric intake via tube feeds, which further reduced to 1.5% (IQR: 0.0%-33.0%) at 6-months, and 0.0% (IQR: 0.0%-35.0%) at 1-year follow-up. The percentage of participants who ate >30 different foods increased from 4.9% at baseline to 81.5% at 1-year follow-up. The baseline median weight z score of -1.24 (IQR: -1.69 to -0.69) decreased to -1.81 (IQR: -2.77 to -1.02) at 1-year follow-up. A linear mixed-effects model demonstrated that weight z score was significantly higher at baseline and 2-weeks compared to the 1-year follow-up (P < 0.001 and P = 0.001, respectively), but was not significantly different between 6 months and 1 year (P = 0.44). Age was not associated with percentage of caloric intake via tube feeds or number of foods eaten., Conclusion: Children who participated in the hunger-based tube-weaning program had increased and more varied oral intake 1 year following the intervention. The median weight z score decreased over the year after intervention but did not significantly decrease between 6 and 12 months after the program., (© 2024 American Society for Parenteral and Enteral Nutrition.)

Objectives: The role of nutrition in the recovery of critically ill children has not been investigated and current nutrition provision in the post-pediatric intensive care unit (PICU) period is unknown. The primary objective of this study was to describe ward nutrition support in children following PICU discharge., Methods: Children up to 18 years admitted to one of nine PICUs over a 2-week period with a length of stay >48 h were enrolled. Data were collected on the first full ward day following PICU discharge and on Days 7, 14, 21, and 28 following PICU admission. Data points included oral intake, enteral (EN) and parenteral nutrition (PN) support, and oral and EN energy and protein provision., Results: Among the 108 children, on the first full ward day 75/108 (69%) children received EN, 54/108 (50%) oral intake, and 8/108 (7%) PN. Of those receiving oral nutrition only on the first full ward day (25/108; 23%), 9/25 (36%) received <50% of their estimated energy and protein requirements. Of those provided EN only, and where nutrition targets were known, on the first full ward day 8/46 (17%) and 7/46 (15%) met <75% of their estimated energy and protein requirements, respectively. On Day 28, this increased to 4/12 (33%) and 5/12 (42%)., Conclusions: In this study of ward-based nutrition support, key findings included consistent use of EN and PN up to at least 28 days following PICU admission, and a high proportion of children receiving EN or oral intake only not meeting their estimated energy and protein requirements., (© 2024 European Society for Pediatric Gastroenterology, Hepatology, and Nutrition and North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition.)

Purpose: This study aimed to identify, through a 28-week follow-up, the association between pain and engagement in different sports among adolescents., Methods: In total, 63 adolescents reported the occurrence of pain, which was tracked weekly. Participants were categorized into 2 groups based on their sports participation: "swimming group" and "other sports group." Researchers directly measured the time spent in different intensities during sports participation for 1 week using a heart rate monitor. For the covariates, body mass, body fatness, and whole-body lean soft tissue were assessed using a dual-energy X-ray absorptiometry scanner. Kaplan-Meier plots and risk of pain were calculated for the absence of pain during the follow-up., Results: The association between the sport type and pain occurrence remained significant even after adjusting the models for potential confounders, showing that swimmers had an increased risk of reporting pain in the neck (HR = 3.33; 95% CI, 1.53-7.25), shoulders (HR = 2.21; 95% CI, 1.17-4.21), and trunk (HR = 5.60; 95% CI, 2.28-13.70)., Conclusion: The association between the sport type and pain occurrence is evident even when controlling for confounding factors.

Background: Although one objective of NHS 111 is to ease the strain on urgent and emergency care services, studies suggest the telephone triage service may be contributing to increased demand. Moreover, while parents and caregivers generally find NHS 111 satisfactory, concerns exist about its integration with the healthcare system and the appropriateness of advice. This study aimed to analyse the advice provided in NHS 111 calls, the duration between the call and ED attendance, and the outcomes of such attendances made by children and young people (C&YP)., Methods: A retrospective cohort study was carried out of C&YP (≤17) attending an ED in the Yorkshire and Humber region of the UK following contact with NHS 111 between 1 April 2016 and 31 March 2017. This linked-data study examined NHS 111 calls and ED outcomes. Lognormal mixture distributions were fit to compare the time taken to attend ED following calls. Logistic mixed effects regression models were used to identify predictors of low-acuity NHS 111-related ED attendances., Results: Our study of 348 401 NHS 111 calls found they were primarily concerning children aged 0-4 years. Overall, 13.1% of calls were followed by an ED attendance, with a median arrival time of 51 minutes. Of the 34 664 calls advising ED attendance 41% complied, arriving with a median of 38 minutes-27% of which defined as low-acuity. Although most calls advising primary care were not followed by an ED attendance (93%), those seen in an ED generally attended later (median 102 minutes) with 23% defined as low-acuity. Younger age (<1) was a statistically significant predictor of low-acuity ED attendance following all call dispositions apart from home care., Conclusion: More tailored options for unscheduled healthcare may be needed for younger children. Both early low-acuity attendance and late high-acuity attendance following contact with NHS 111 could act as useful entry points for clinical audits of the telephone triage service., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Healthcare delivery is made more convenient and effective via telemedicine, which enables physicians to conduct virtual consultations and evaluations with pediatric patients. The purpose of this systematic review was to evaluate the efficacy of telemedicine as compared to physical appointments in the pediatric population. We used Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to search for the available literature using pre-specified inclusion and exclusion criteria. These databases provided 968 relevant research articles, which Endnote software screened for duplicates. Fourteen studies were considered relevant for full-text evaluation. After complete text evaluation, only 11 of these articles were found to be relevant. The Newcastle-Ottawa Scale (NOS) was used for the risk of bias assessment of all included studies. Eleven articles in all satisfied the requirements for inclusion and were added to the review. Every study was classified as either a cluster randomized trial (27%) or a randomized controlled trial (RCT) (73%). There were between 22 and 400 participants in each trial. Medical conditions evaluated included obesity (27%), mental health disorders (9%), asthma (18%), otitis media (9%), skin disorders (9%), type 1 diabetes (9%), attention deficit hyperactivity disorder (ADHD) (9%), and pancreatic insufficiency associated with cystic fibrosis (1/11). Telemedicine strategies employed included telemedicine-based screening visits (9%), smartphone-based therapies (27%), phone counseling (18%), and videoconferencing visits between patients and doctors (45%). The outcomes of the telemedicine procedures in every included study were on par with or superior to those of the control groups. Medication adherence, appointment completion rates, life satisfaction, symptom management, and disease progression were all outcomes associated with these findings. Although more research is needed, the evidence from this review suggests that telemedicine services for the general public and pediatric care are comparable to or better than in-person services. Patients, healthcare professionals, and caregivers may benefit from using both telemedicine services and traditional in-person healthcare services. To maximize the potential of telemedicine, future research should focus on improving patients' access to care, increasing the cost-effectiveness of telemedicine services, and eliminating barriers to telemedicine use., Competing Interests: Conflicts of interest: In compliance with the ICMJE uniform disclosure form, all authors declare the following: Payment/services info: All authors have declared that no financial support was received from any organization for the submitted work.

We report five cases of spider angiomas in children treated topically with timolol 0.5% (ophthalmic solution or gel-forming solution), for 6 months. Parents and patients were advised to apply one drop twice daily. Four of them showed either partial (2) or complete response (2) and only one patient had no clinical change. No adverse effects were reported. This pilot case series shows that topical timolol may prove useful as a noninvasive, available and well-tolerated treatment option for spider angiomas in children who seek a treatment alternative to pulsed dye laser., (© 2024 Wiley Periodicals LLC.)

Evidence suggests that pediatric palliative care involvement (PPC) is beneficial to medically complex patients. Historically, PPC involvement has been overlooked or delayed and varies by institution but PPC awareness has increased in cardiovascular ICUs (CVICU) and so we investigated frequency and timeliness of PPC referral for patients dying in ICU. Retrospective study of pediatric cardiac patients experiencing death in ICU to review PPC presence and timing of initial PPC, most recent PPC, and interventions, therapies, CPR, and presence of do-not-resuscitate DNR discussion. Fifty-four patients died during a 5-year period aged 11d-17y (54% male). PPC involvement occurred in 40/54 (74%). Of those patients without PPC, the Center to Advance Palliative Care (CAPC) guidelines would have supported PPC in 11/14 (79%). DNR discussion was more likely in PPC patients (63% vs 14%; p = 0.0011), though often only on DOD. Comparing prior to DOD, PPC patients were still more likely to have DNR discussion (55% vs 0%; p = 0.0003). PPC patients were no less likely to have CPR on DOD (28% vs 43%, p = 0.29). PPC occurred frequently in patients experiencing death in CVICU. However, frequently the initial PPC occurred within a week or day of death. Patients without PPC would often qualify under published guidelines. Standardization, timing, and patient identification for PPC will expand efficacy in CVICU., (© 2024. The Author(s).)

Background: Trauma-induced coagulopathy (TIC) is associated with negative outcomes. Pediatric TIC has been described most often in older children. Children undergo normal developmental hemostasis, but it is unknown how this process impacts the risk of TIC across childhood., Aims: To understand variations in coagulation testing and TIC across pediatric age groups., Methods: We evaluated testing patterns of coagulation studies at presentation and over the first 72 h of hospitalization by pediatric age group at a large, Level I trauma center, 2015-2020. The frequency of TIC was determined using published, age-specific reference ranges and controlling for injury severity. We performed subgroup analyses of those with isolated severe traumatic brain injury (TBI) and those who presented directly from the scene of injury., Results: Data from 2409 pediatric patients were available; 333 patients had isolated severe TBI. Children <1 year were least likely to be tested for TIC at presentation and over the first 72 h, even among the most injured. Fibrinogen testing was uncommon, regardless of injury severity. TIC was common: 22% of patients had TIC at presentation and 35% by 72 h. Greater injury severity was associated with TIC. Children 1-4 and 5-9 years had a higher frequency of TIC at presentation and over 72 h compared to older children in the least injured cohort. We saw no difference in frequency of TIC between age groups in the subset with isolated severe TBI. Using age-specific criteria, patients most often met TIC criteria by INR/PT, followed by platelet count, and least commonly by aPTT. The presence of TIC was associated with in-hospital mortality (OR 4.10, 95% CI 2.06-8.17)., Conclusions: Significant sampling bias exists in clinical data collection among injured children and adolescents. Contrary to previous reports and using age-specific TIC criteria, younger children are not at lower risk of TIC than older children when controlling for injury severity., (© 2024 John Wiley & Sons Ltd.)

Background: Surveillance for heart transplant rejection by endomyocardial biopsy is invasive and may yield false negatives. T1 and T2 mapping from cardiac magnetic resonance can demonstrate elevations with rejection. We sought to evaluate longitudinal changes in T1 and T2 mapping in pediatric patients with heart transplant., Methods and Results: A cohort study was performed of pediatric patients with heart transplant who underwent concurrent endomyocardial biopsy and cardiac magnetic resonance with T1 and T2 mapping from December 2019 to July 2024. Segmental values were measured and subsegmental elevations (ie, hotspots) were identified. Subjects were categorized as either treated rejection or no rejection. Peak and mean T1 and T2 values and number of hotspots at/between each time point for patient dyads were compared between the groups. A total of 21 subjects (7 treated rejection, 14 no rejection) with 68 total encounters met inclusion criteria. Peak and mean T1 values were higher in treated rejection patients during the rejection period and decreased with treatment (peak, 1086 versus 1052; mean, 1028 versus 1021), such that at last follow-up when their rejection had resolved, there was no significant difference in values when compared with no rejection patients (peak, 1066; mean, 1016). The number of T1 hotspots decreased after rejection treatment (2 versus 1). There were no changes in peak or mean T2 values in the treated rejection group despite treatment, and peak and mean T2 values were similar to patients with no rejection through last follow-up., Conclusions: Elevated T1 values and hotspots observed during cardiac allograft rejection decline in response to treatment. Cardiac magnetic resonance may serve as a noninvasive monitoring tool for the development and resolution of rejection, as well as the effectiveness of rejection therapy.

Background/Objectives : As congenital syphilis incidence continues to increase yearly in the United States (US), recommendations from government and professional organizations aim to inform effective clinical practice, although it is unclear how closely these recommendations are followed. This study surveyed US pediatric specialists regarding their approach to congenital syphilis diagnosis and treatment to examine decision-making relative to practice guidelines and subspecialty. Methods : US pediatric physicians recruited from subspecialty directories were sent an online survey conducted in March-April 2024. The case-based survey elicited diagnostic and treatment decisions for different case definitions of congenital syphilis (proven or highly probable, possible, and less likely). Results : Among 442 respondents (56.8% women, 74.2% age 40-69, 57.7% 15+ years since training completion), 94.1% chose to evaluate and manage proven or highly probable congenital syphilis as recommended whereas only 45.8% did so for congenital syphilis considered less likely. Diagnostic and treatment decisions by infectious disease specialists and other subspecialists differed across case definitions. Conclusions : Physicians' approaches to congenital syphilis workup and management, including the decision to treat, varied with case presentation where decision-making seemed to diverge from published recommendations and between subspecialists as infection became less likely by case definition.

The HEALthy Brain and Child Development (HBCD) Study, a multi-site prospective longitudinal cohort study, will examine human brain, cognitive, behavioral, social, and emotional development beginning prenatally and planned through early childhood. The HBCD study has faced several ethical and legal challenges due to its goal of enrolling pregnant people (including those with substance use disorder) and their newborns. Challenges not fully anticipated at the outset emerged from the rapidly changing legal landscape around reproductive rights in the United States. By embedding scholars in bioethics and law within research teams and engaging them in conversation with each other and other study personnel, we were able to address many challenges proactively and respond promptly to unanticipated challenges. In this paper, we highlight several important ethical and legal challenges that arose from the first phase of funding through the beginning of participant enrollment. We explain the methods used to address these challenges, the ethical and legal tradeoffs that arose, and the resolution of challenges through the design of the study. Based on this experience, we provide recommendations for research teams, sponsors, and reviewers to address legal risks and promote the ethical conduct of studies with pregnant people and caregivers. We highlight the importance of collaboration with bioethics and legal scholars in studies involving complex and evolving legal risks, as well as the necessity of designing robust approaches to informed consent and maintaining participant trust while navigating ethical challenges in research., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests.

Background Child abuse is a significant cause of morbidity and mortality in children. A thorough history and physical exam is critical to identifying abuse. Standardized screening tools as well as clinical pathways can assist with identifying patients who may have an injury secondary to abuse. There are varied recommendations for the upper age in which to routinely evaluate pediatric patients for child abuse. Objectives The primary objective of this study was to describe the outcomes of the implementation of an evidence-based clinical pathway for suspected non-accidental trauma for all pediatric patients aged five years and under presenting with a femur fracture. This pathway includes orders for imaging, labs, and consults. In addition, the characteristics of this population and the findings were described. Methods A retrospective study of patients at a single institution who met the National Trauma Data Standard registry inclusion criteria and had a femur fracture was performed. Variables analyzed included age, demographics, mechanism and location of injury, admission status and service, injury severity, hospital characteristics, and discharge status. Patients with a metabolic bone disease were excluded. Results There were 200 patients who met the inclusion criteria. Thirty-two patients had a diagnosis of confirmed or suspected child abuse. While all 32 patients had a skeletal survey performed, only 23 (71.9%) had the complete workup per the clinical pathway, and 21 (65.6%) had a diagnosis of confirmed child abuse. Conclusion Clinical pathways are established to provide the standardization of clinical assessments and interventions; however, this process relies on a single individual to make a judgment determining whether or not to implement the pathway. Children presenting to an emergency department with confirmed or suspected child abuse are a vulnerable population. A child abuse diagnosis is a clinical judgment; however, clinical pathways aid in the diagnosis in hopes to stop any further abuse. For a pathway to be successful, each step needs to be addressed., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Polyarteritis nodosa (PAN) is a rarely seen vasculitis that often affects small-sized and medium-sized arteries. PAN can present with diverse clinical features depending on the organs involved, including potential cardiac involvement. Typical cardiac manifestations of PAN in the paediatric age group include pericarditis, valvular heart disease and coronary artery aneurysms. In contrast to PAN, Kawasaki disease (KD) is often associated with coronary artery abnormalities. Herein, we report a case of a young boy presented with KD-like features, including a coronary artery aneurysm confirmed by an echocardiogram (ECHO) and eventually diagnosed as PAN. The patient was treated with steroids, methotrexate and tocilizumab with improvement of the symptoms. Repeated ECHO revealed the resolution of the coronary artery aneurysms. Our paper highlights a rare presentation of PAN mimicking KD presentation. Physicians should consider PAN in chronic or severe courses of KD or coronary artery aneurysms., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2024.

Background: Antimicrobial stewardship programs (ASP) often function naturally as facilitators within clinical hospital settings, by working with individuals and teams to reduce unnecessary antibiotics. Within implementation science, facilitation has been studied and evaluated as an implementation strategy that can accelerate and improve fidelity to implementation efforts. This study describes a novel, virtual facilitation strategy developed and served as an intervention within the optimizing perioperative antibiotics for children trial (OPERATIC trial). This paper: (1) describes ASP team's preferences for and use of a facilitation workshop and (2) describes sustained use of facilitation skills throughout the study period., Methods: Study participants included antimicrobial stewardship team members from the nine children's hospitals that participated in this study and completed facilitation training. All individuals who completed facilitation training were asked to evaluate the training through an online survey. Additionally, site leads were interviewed by the site coordinator every other month and asked about their team's use of facilitation skills throughout the rest of the study period. Survey data were managed and coded in R, and qualitative interview data were analyzed using rapid methodology., Results: 30 individuals, including both physicians and pharmacists, completed the evaluation. Individuals largely rated themselves as novice facilitators (53%). Individuals reported satisfaction with virtual facilitation and identified different components of the workshops as valuable. An additional 108 interviews were performed throughout the study period. These interviews found that facilitators reported using all skills throughout the study period and described varied use of skills over time. All nine sites applied facilitation strategies, team building techniques, and communication/conflict skills at some point during the intervention phase., Conclusion: We describe the use of virtual facilitation as an acceptable and appropriate strategy to enhance facilitation skills for ASP teams working to reduce unnecessary postoperative antibiotics. Participants reported different useful components of facilitation training and described using differing facilitation skills throughout the trial. Overall, the use of facilitation skills continued throughout the duration of the study period. This paper outlines how facilitation training can be conducted virtually in a way that is feasible and acceptable to clinicians., Trial Registration: NCT04366440, April 24, 2020., (© 2024.

Adequate sleep tailored to children's age is important for their well-being. This study aimed to examine the association between adequate sleep and children's participation in occupational areas. This study was a retrospective cross-sectional analysis of secondary data obtained from the 2020 National Survey of Children's Health in the United States. This study included 6,818 children aged 6 to 11 years. The mean age was 8.48 years (standard deviation = 1.72). Multivariate regression models revealed that adequate sleep was significantly associated with increased participation in occupational areas (17% more in leisure, 95% confidence interval [CI]: 1.11-1.23; 15% more in play, 95% CI: 1.07-1.22; 11% more in education, 95% CI: 1.01-1.22) in school-age children, but not with participation in work and social participation. Adequate sleep is associated with increased participation of school-age children in occupational areas., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Objectives: The COVID-19 pandemic has had a profound effect on the pediatric population worldwide. The consequences of the lockdown and the reallocation of hospital resources have caused notable changes in the presentation of pediatric orthopedic injuries. Through our use of patient records, we were able to display the epidemiological trends, as well as analyze the changes in the type and mechanism of various injuries. Our purpose is to further understand the considerable effects of the COVID-19 pandemic on pediatric orthopedic trauma and help guide the allocation of future healthcare resources., Methods: We conducted a retrospective cohort study on pediatric patients admitted for any orthopedic injury over a 3-year period (September 2018 to August 2021) at a Midwest level 1 trauma center. Cases were stratified into two groups based on the United States' COVID-19 lockdown (19 March 2020): Pre-COVID-19 cases were any cases prior to the lockdown and Intra-COVID-19 which are cases following the lockdown. Numerical data and categorical variables were summarized and differences between the case groups were examined using either two-Proportion Z-Test, Independent Two-Sample t -test, Pearson's chi-squared, or Fisher's exact tests., Results: A total of 3179 pediatric orthopedic referrals occurred between the Pre-COVID-19 and Intra-COVID-19 study periods. We observed a general decrease in orthopedic injuries following the COVID-19 lockdowns with 1235 injuries compared to 1606 Pre-COVID-19. Patterns in the locations of injuries changed; notably, fractures of the humerus, tibia, and fibula decreased significantly ( p < 0.05). Several mechanisms of injuries decreased significantly following the onset of COVID-19 including injuries caused by monkey bars, basketball, and automobiles ( p < 0.01). There was a significant increase in the overall injury severity during the Intra-COVID-19 period ( p < 0.05)., Conclusions: Although there was a reduction in acute orthopedic trauma referrals, many injury mechanisms displayed similar trends regardless of restrictions. We clinically observed an overall increase in the severity of pediatric orthopedic injuries during the COVID-19 pandemic.
