Risk factors for mortality in children with hemorrhagic cystitis after hematopoietic transplant.

INTRODUCTION: Hemorrhagic cystitis (HC) is a devastating complication of bone marrow (BMT) and stem cell transplant (SCT). Much of the literature has focused on exclusively adult patient populations, with limited evidence regarding risk factors for mortality and morbidity among pediatric HC patients. OBJECTIVE: To examine factors associated with all-cause mortality in children with HC after BMT/SCT. METHODS: The Pediatric Health Information System database was queried for patients with ICD-9/10 codes for hematopoietic transplant and gross hematuria, hematuria unspecified, or cystitis with hematuria. Multivariable logistic regression examined association of medical and surgical interventions frequently employed for hemorrhagic cystitis with mortality and genitourinary morbidity, defined as having received instillation of any bladder medication or having undergone any genitourinary procedure. RESULTS: A total of 811 patients, mean age of 12.4 years and 62% male, were included. Primary diagnosis included 388 (49%) leukemia/lymphoma, 182 (22%) blood dyscrasia, 99 (12%) solid organ tumor, 27 (3%) metabolic disease, 115 (14%) unknown. Transplant type included 377 (46%) bone marrow, 329 (41%) stem cell, 105, and (13%) unknown. Performing any bladder instillation (p < 0.0001) or any type of GU procedure (p < 0.0001) was significantly associated with mortality. On multivariate analysis, dialysis (OR = 10.7, 95% CI = 5.7-20.2), genitourinary morbidity (OR = 4, 95% CI = 2.2-6.8) and intravenous cidofovir (OR = 2.0, 95% CI = 1.2-3.3) were significantly associated with all cause mortality. Having an underlying diagnosis of blood dyscrasia was protective against mortality (OR = 0.425, CI = 0.205-0.88). DISCUSSION: In this large retrospective study evaluating factors associated with mortality in children with HC, all cause mortality was found to be 11%. This is probably an underrepresentation of true mortality in this population, as many patients discharged from the hospital likely die outside the hospital at home or hospice care. This study supports the current literature that invasive GU procedures are not associated with increased survival in patients with severe HC. This study is limited by retrospective use of a billing database that has the potential for errors in data entry and missing data. Patients who were discharged from the hospital were not captured by the PHIS which only collects data from inpatient stays. CONCLUSIONS: Patients with HC who received dialysis, intravenous cidofovir, or underwent GU intervention had significantly higher all-cause mortality. High grade HC is a marker of disease severity and efforts should be made by urologists and oncologists to maximize quality of life and limit futile treatments in this patient population.

Nicardipine or Nitroprusside for Postoperative Blood Pressure Control in Infants After Surgery for Congenital Heart Disease: Single-Center Retrospective Noninferiority and Cost Analysis, 2016-2020.

OBJECTIVES: Postoperative hypertension frequently occurs after surgery for congenital heart disease. Given safety concerns when using calcium channel blockers in infants along with the cost and side-effect profile of nitroprusside, we retrospectively assessed our experience of using nicardipine and nitroprusside for postoperative blood pressure control in infants who underwent surgery for congenital heart disease. We also investigated the cost difference between the medications. DESIGN: This study was a single-center retrospective, pre-post chart review of patients who had surgery for congenital heart disease between 2016 and 2020. The primary aim was a noninferiority comparison of achievement of blood pressure goal at 1-hour post-initiation of an antihypertensive agent. Secondary comparisons included achievement of blood pressure goal at 2 hours after medication initiation, Vasoactive-Inotropic Score (VIS), and blood transfusion, crystalloid volume, and calcium needs. SETTING: Academic quaternary-care center. PATIENTS: Infants under 1 year old who required treatment for hypertension with nitroprusside (n = 71) or nicardipine (n = 52) within 24 hours of surgery for congenital heart disease. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We failed to identify any difference in proportion of patients that achieved blood pressure control at 1-hour after medication initiation (nitroprusside 52% vs. nicardipine 54%; p = 0.86), with nicardipine noninferior to nitroprusside within a 15% margin. Of patients who did not achieve control at 1-hour post-medication initiation, receiving nicardipine was associated with blood pressure control at 2 hours post-medication initiation (79% vs. 38%; p = 0.003). We also failed to identify an association between antihypertensive types and mean VIS scores, blood transfusion volumes, crystalloid volumes, and quantities of calcium administered. Index cost of using nitroprusside was 16 times higher than using nicardipine, primarily due to difference in wholesale cost. CONCLUSIONS: In our experience of achieving blood pressure control in infants after surgery for congenital heart disease (2016-2020), antihypertensive treatment with nicardipine was noninferior to nitroprusside. Furthermore, nicardipine use was significantly less expensive than nitroprusside. Our contemporary practice is therefore to use nicardipine in preference to nitroprusside.

Resting-State Functional Magnetic Resonance Imaging Network Association With Mortality, Epilepsy, Cognition, and Motor Two-Year Outcomes in Suspected Severe Neonatal Acute Brain Injury.

BACKGROUND AND OBJECTIVES: In acute brain injury of neonates, resting-state functional magnetic resonance imaging (MRI) (RS) showed incremental association with consciousness, mortality, cognitive and motor development, and epilepsy, with correction for multiple comparisons, at six months postgestation in neonates with suspected acute brain injury (ABI). However, there are relatively few developmental milestones at six months to benchmark against, thus, we extended this cohort study to evaluate two-year outcomes. METHODS: In 40 consecutive neonates with ABI and RS, ordinal scores of resting-state networks; MRI, magnetic resonance spectroscopy, and electroencephalography; and up to 42-month outcomes of mortality, general and motor development, Pediatric Cerebral Performance Category Scale (PCPC), and epilepsy informed associations between tests and outcomes. RESULTS: Mean gestational age was 37.8 weeks, 68% were male, and 60% had hypoxic-ischemic encephalopathy. Three died in-hospital, four at six to 42 months, and five were lost to follow-up. Associations included basal ganglia network with PCPC (P = 0.0003), all-mortality (P = 0.005), and motor (P = 0.0004); language/frontoparietal network with developmental delay (P = 0.009), PCPC (P = 0.006), and all-mortality (P = 0.01); default mode network with developmental delay (P = 0.003), PCPC (P = 0.004), neonatal intensive care unit mortality (P = 0.01), and motor (P = 0.009); RS seizure onset zone with epilepsy (P = 0.01); and anatomic MRI with epilepsy (P = 0.01). CONCLUSION: For the first time, at any age, resting state functional MRI in ABI is associated with long-term epilepsy and RSNs predicted mortality in neonates. Severity of RSN abnormality was associated with incrementally worsened neurodevelopment including cognition, language, and motor function over two years.

Screening for juvenile idiopathic arthritis associated uveitis with laser flare photometry in the pediatric rheumatology office: a prospective observational study.

BACKGROUND: Juvenile Idiopathic Arthritis (JIA) Associated Uveitis (JIA-U) remains one of the most serious complications of JIA in children. Historically, pediatric JIA is diagnosed by an Optometrist or Ophthalmologist; however, barriers to scheduling increase wait times that may delay diagnosis and treatment. The purpose of this study was to evaluate laser flare photometry (LFP) use to diagnose JIA-U in the Pediatric Rheumatology clinic for patients with JIA. METHODS: This prospective, observational study assessed pediatric patients diagnosed with JIA without a previous history of uveitis between January 2020 and September 2022. All patients underwent at least one evaluation of both eyes using a Kowa FM-600 laser flare photometer during a routine Rheumatology appointment, as well as a standard slit lamp examination (SLE) by optometry or ophthalmology during routine clinical care. Data collected at patient visits included demographics, JIA characteristics, treatment, LFP readings, and anterior chamber (AC) cell grade score utilizing the SUN grading system. Data were summarized using descriptive analyses and the uveitis false positive rate was calculated. RESULTS: The study cohort included 58 pediatric patients diagnosed with JIA. The mean age was 8.4 years (1.2-16.3 years) at diagnosis and 11.9 (4.8-16.5 years) at enrollment. The mean duration of disease at time of enrollment was 42 months (range; 0-157 months). Participants were predominantly female (n = 43, 74.1%) and white/Caucasian race (n = 37, 63.8%). The most common JIA subtypes included persistent oligoarticular JIA (n = 19, 32.8%), and RF negative polyarticular JIA (n = 12, 20.7%). There were 12 ANA positive patients (20.7%). At enrollment, 16 patients (27.6%) were not on medications, with 20 (34.5%) on methotrexate, 20 (34.5%) on adalimumab, 6 (10.3%) on tocilizumab, and 5 (8.6%) on etanercept. During the study period, no eye exams detected active uveitis based on SLE with a SUN grade over 0. However, of the 135 LFP readings, 131 (97.0%) were normal, yielding a false positive rate of 3% (95% CI: 0.8%, 7.4%). CONCLUSIONS: LFP is a non-invasive tool that can be utilized in the pediatric rheumatology clinic to evaluate for JIA-U. There is a low false positive rate of LFP when compared with standard slit lamp exam.

Congenital heart surgery outcomes in patients with positive respiratory viral swabs.

OBJECTIVE: To examine whether or not viral positive patients experienced worse outcomes and assess differences in surgical outcomes between viral-positive patients with and without viral symptoms within 30 days of surgery. METHODS: This retrospective study reviewed charts of pediatric patients who underwent congenital heart surgery and routine viral testing at a single institution over a consecutive 3-year period (2017-2019). Patients with a history of heart transplants, pacemaker changes, or implants, and mediastinal washouts were excluded from the study. Surgical outcomes were compared by viral status and viral symptoms, using the Fisher exact and Wilcoxon rank sum tests. RESULTS: Among 1041 patients, 374 patients underwent routine preoperative viral testing, with 107 patients testing positive and 267 testing negative for viral swabs before surgery. There were no significant differences observed in surgical outcomes by viral status, including no differences in mortality. Among the 107 patients with positive viral swabs before surgery, comparisons between 24 patients with viral symptoms and 83 without symptoms within 30 days of surgery detected no significant differences in mortality or complication rates. However, symptomatic versus asymptomatic patients had significantly longer postoperative stay (23.4 vs 13.4 days; P = .02) and intubation time (9.8 vs 4.9 hours; P = .004). CONCLUSIONS: Patients who test positive before congenital heart surgery and are asymptomatic beyond the incubation period may proceed to surgery with no further delay. Patients who are viral positive and symptomatic have a longer postoperative stay and intubation time. A prospective study is needed to assess the importance of routine viral testing.

Effect of Viral Illness on Procalcitonin as a Predictor of Bacterial Infection in Febrile Infants.

OBJECTIVE: The impact of confirmed viral infections (CVI) on procalcitonin (PCT) levels in febrile infants aged 8-60 days with a bacterial illness (BI) is unknown. The objectives of the study were to (1) examine the association of CVI with PCT levels in patients with/without a concurrent BI, defined as bacteremia, meningitis, or urinary tract infection, and (2) assess PCT as a predictor of BI in infants with a concurrent CVI. METHODS: In this single-center, retrospective cohort study, we examined febrile infants aged 8-60 days presenting between January 1, 2018 and December 31, 2020. PCT levels were compared between groups, according to results of bacterial cultures and viral tests, using the Wilcoxon rank test. The prediction ability of PCT to detect BI with/without concurrent CVI was assessed by using area under the curve from logistic regression. RESULTS: Patients included: 404 BI-/CVI+, 73 BI+/CVI-, 48 BI+/CVI+, and 138 BI-/CVI-. Median PCT level in the BI+/CVI+ group was significantly lower when compared to BI+/CVI- (0.36 ng/mL vs 0.89 ng/mL), but significantly higher than the BI-/CVI- group (0.36 ng/mL vs 0.1 ng/mL). The presence of a CVI reduced the sensitivity of PCT in BI detection (68% vs 44%), with minimal impact specificity (93% vs 96%). CONCLUSIONS: In previously healthy febrile infants 8-60 days old, the presence of a CVI reduces the sensitivity of PCT BI detection without impacting its specificity. The impact of a CVI on PCT levels in febrile infants has implications for how this marker of infection should be considered when assessing risk of BI in infants.

Efficacy of Azacitidine and Prophylactic Donor Lymphocyte Infusion after HSCT in Pediatric Patients with Acute Myelogenous Leukemia: A Retrospective Pre-Post Study.

Pediatric patients with acute myeloid leukemia (AML) who undergo allogeneic hematopoietic stem cell transplantation (HSCT) continue to have high rates of relapse. In 2018, Phoenix Children's Hospital started using post-HSCT maintenance therapy in patients with AML in attempt to decrease the number of relapses after HSCT. This therapy consisted of the hypomethylating agent azacitidine (AZA; 6 cycles starting on day +60) and prophylactic donor lymphocyte infusion (DLI; 3 escalating doses beginning after day +120). We aimed to compare 2-year leukemia-free survival (LFS) post-HSCT between patients with AML who received post-HSCT maintenance therapy with AZA and prophylactic DLI and historical control patients who did not receive post-HSCT therapy. This retrospective pre-post study was conducted at Phoenix Children's Hospital and included patients with AML who underwent HSCT between January 1, 2008, and May 31, 2022. We compared LFS, overall survival (OS), and immune reconstitution patterns post-HSCT between patients with AML who received post-HSCT maintenance therapy with AZA and prophylactic DLI (postintervention group) and historical control patients who did not receive this post-HSCT maintenance therapy (preintervention group). Sixty-three patients were evaluable. After excluding 7 patients who died or relapsed prior to day +60, 56 patients remained, including 39 in the preintervention group and 17 in the postintervention group. The median age at transplantation was 9.1 years in the preintervention group and 11 years in the postintervention group (P = .33). The 2-year LFS was 61.5% in the preintervention group, compared to 88.2% in the postintervention group (P = .06). The 2-year OS was 69.2% in the preintervention group and 88.2% in the postintervention group (P = .15). The rates of CD3+CD4+ T cell and CD19+ B cell recovery were faster in the preintervention group compared to the postintervention group (P = .004 and .0006, respectively). In this limited retrospective study, post-HSCT maintenance therapy using AZA and prophylactic DLI was well tolerated; however, its efficacy is yet to be fully determined.

Vitamin D Supplementation: Association With Serum Cytokines in Pediatric Hematopoietic Stem Cell Transplantation.

Vitamin D deficiency is prevalent in pediatric patients presenting for hematopoietic stem cell transplantation (HSCT) and has been linked to poor clinical outcomes. Using the data from a randomized control trial, in this paper we explore the effects of vitamin D supplementation on circulating cytokine levels during pediatric HSCT (www.clinicaltrials.gov as NCT03176849). A total of 41 children, 20 received Stoss therapy and 21 children received standard of care vitamin D supplementation. Levels of 25(OH)D and 20 cytokines were assessed at baseline and day +30. Significantly (P < 0.05) higher levels of mostly proinflammatory cytokines, FGF, GCSF, TNFα, IL-2, IL-6, IP10 were detected pre-transplant for patients with low compared to those with normal vitamin D levels. In sex stratified models that compare changes in cytokines between Stoss vs. standard of care, females in the Stoss group show greater changes in mostly pro -inflammatory cytokines- IP-10 (P = 0.0047), MIG (P = 0.009), and RANTES (P = 0.0047), IL-2R (P = 0.07) and IL-6(P = 0.069). Despite a small sample size, these findings suggest vitamin D deficiency affects the pre-transplant cytokine milieu and higher doses of vitamin D (Stoss therapy) appears to influence proinflammatory cytokine responses in a sex specific manner during pediatric HSCT. Larger clinical trials are warranted to validate these results.

Impact of Adequate Day 30 Post-Pediatric Hematopoietic Stem Cell Transplantation Vitamin D Level on Clinical Outcome: An Observational Cohort Study.

This prospective observational study evaluated the impact of adequate vitamin D levels by day +30 after vitamin D supplementation on early post-HSCT outcomes, including acute graft-versus-host disease (aGVHD), immune recovery, infection rates, and overall survival. Forty children (age 2 to 16 years) undergoing hematopoietic stem cell transplantation (HSCT) were given vitamin D supplementation, were followed prospectively from day +30 post-transplantation, and had day +30 vitamin D levels measured. Thirty patients with normal vitamin D levels (≥30 ng/mL) were compared with 10 patients with low day +30 vitamin D levels (<30 ng/mL). The times to neutrophil and platelet engraftment was similar in both day +30 vitamin D groups (P = .13 and .32, respectively). At day +100, slower immune recovery in CD4+ cells (P = .027), CD19+ cells (P = .024), and natural killer cells (P = .042) was observed in the patients with a low vitamin D level (<30 ng/mL), and no between-group differences were detected in the incidence of infection (P = .72) or grade II-IV aGVHD (P = .46). Our findings show that patients with adequate vitamin D levels during transplantation had faster immune recovery and better overall survival. Vitamin D deficiency does not appear to impact engraftment or the risk of aGVHD and infection in pediatric HSCT.

Late-Career Pediatric Hospitalists: Programmatic Accommodations and Supports.

BACKGROUND: As the number of late-career pediatric hospitalists increases, issues regarding aging and retirement will require more attention. Long shifts and overnight clinical responsibilities may be challenging for older physicians. Our study objectives include investigation of the current state of practice regarding work hours, night call responsibilities, productivity requirements, coronavirus disease 2019 (COVID-19) exposure modifications, and division chief knowledge about retirement supports for late-career pediatric hospitalists. METHODS: This cross-sectional study used a web survey, distributed in spring of 2020 on the American Academy of Pediatrics, Section on Hospital Medicine, Division Chief listserv. The questionnaire asked about (1) program demographics, (2) overnight call responsibilities, (3) clinical schedules, (4) modifications for COVID-19, and (5) retirement benefits and supports. Data were analyzed by using descriptive statistics and the Fisher exact test. RESULTS: The 47 responding programs employ 982 hospitalists in 728 full-time equivalent positions. Division chiefs estimated 117 (12%) individuals were aged 50 to 64 years and 16 (1.6%) were 65 years or older. Most programs (91%) had at least 1 member 50 to 64 years of age; 13 programs (28%) had a member aged 65 or older. Larger programs were more likely to allow older physicians to opt out of some night call responsibilities. Most programs made some accommodations for COVID-19 exposure. Other than financial counseling and academic benefits, most programs did not provide retirement counseling or other supports for retiring physicians. CONCLUSION: Although limited by a low response rate, we found most programs had older faculty. Substantial variation exists in how programs make accommodations and offer support for older members.

Association of Psychiatric Comorbidities With Treatment and Outcomes in Pediatric Migraines.

BACKGROUND AND OBJECTIVES: Migraine headache is a common disorder in pediatrics, sometimes leading to hospital admission. Psychiatric comorbidities are prevalent in adults with migraine headache, but there is limited evidence in the pediatric population. This study aimed to examine the prevalence of psychiatric comorbidity in children hospitalized for migraine headache and assess the association of this comorbid state on treatment interventions and outcomes. METHODS: This multicenter, retrospective cohort study examined data from the Pediatric Health Information System. Subjects included patients aged 6 to 18 hospitalized for migraine headache between 2010 and 2018, excluding those with complex chronic conditions. Associations of psychiatric comorbidity with treatments, length of stay (LOS), cost, and 30-day readmissions were assessed using the Fisher-exact, Wilcoxon-rank-sum test, and adjusted linear or logistic regression models. RESULTS: The total 21 436 subjects included 6796 (32%) with psychiatric comorbidity, with prevalence highest for anxiety (2415; 11.2%), depression (1433; 6.7%), and attention-deficit/hyperactivity disorder (1411; 6.5%). Patients with psychiatric comorbidity were significantly more likely (P < .001) to receive dihydroergotamine (61% vs 54%), topiramate (23% vs 18%), and valproate (38% vs 34%), and have longer mean LOS (2.6 vs 2.0 days), higher average costs ($8749 vs $7040), and higher 30-day readmission (21% vs 17%). CONCLUSIONS: Of children hospitalized for migraine headache, 32% have comorbid psychiatric disorders associated with increased use of medications, longer LOS, and increased cost of hospitalization and readmission. Prospective studies are recommended to identify optimal multidisciplinary care models for children with migraine headaches and psychiatric comorbidities in the inpatient setting.

Association of network connectivity via resting state functional MRI with consciousness, mortality, and outcomes in neonatal acute brain injury.

BACKGROUND: An accurate and comprehensive test of integrated brain network function is needed for neonates during the acute brain injury period to inform on morbidity. This retrospective cohort study assessed whether integrated brain network function acquired by resting state functional MRI during the acute period in neonates with brain injury, is associated with acute exam, neonatal mortality, and 6-month outcomes. METHODS: Study subjects included 40 consecutive neonates with resting state functional MRI acquired within 31 days after suspected brain insult from March 2018 to July 2019 at Phoenix Children's Hospital. Acute-period exam and test results were assigned ordinal scores based on severity as documented by respective treating specialists. Analyses (Fisher exact, Wilcoxon-rank sum test, ordinal/multinomial logistic regression) examined association of resting state networks with demographics, presentation, neurological exam, electroencephalogram, anatomical MRI, magnetic resonance spectroscopy, passive task functional MRI, and outcomes of discharge condition, outpatient development, motor tone, seizure, and mortality. RESULTS: Subjects had a mean (standard deviation) gestational age of 37.8 (2.6) weeks, a majority were male (63%), with a diagnosis of hypoxic ischemic encephalopathy (68%). Findings at birth included mild distress (48%), moderately abnormal neurological exam (33%), and consciousness characterized as awake but irritable (40%). Significant associations after multiple testing corrections were detected for resting state networks: basal ganglia with outpatient developmental delay (odds ratio [OR], 14.5; 99.4% confidence interval [CI], 2.00-105; P < .001) and motor tone/weakness (OR, 9.98; 99.4% CI, 1.72-57.9; P < .001); language/frontoparietal network with discharge condition (OR, 5.13; 99.4% CI, 1.22-21.5; P = .002) and outpatient developmental delay (OR, 4.77; 99.4% CI, 1.21-18.7; P=.002); default mode network with discharge condition (OR, 3.72; 99.4% CI, 1.01-13.78; P=.006) and neurological exam (P = .002 (FE); OR, 11.8; 99.4% CI, 0.73-191; P = .01 (OLR)); and seizure onset zone with motor tone/weakness (OR, 3.31; 99.4% CI, 1.08-10.1; P=.003). Resting state networks were not detected in three neonates, who died prior to discharge. CONCLUSIONS: This study provides level 3 evidence (OCEBM Levels of Evidence Working Group) demonstrating that in neonatal acute brain injury, the degree of abnormality of resting state networks is associated with acute exam and outcomes. Total lack of brain network detection was only found in patients who did not survive.

Annual Mammographic Screening Reduces the Risk of Interval or Higher Stage Invasive Breast Cancers Among Postmenopausal Women in the Ontario Breast Screening Program.

Purpose: In the Ontario Breast Screening Program (OBSP) annual screening improved breast cancer detection for women 50-74 years with a family/personal history compared to biennial, while detection was equivalent for women screened annually for mammographic density ≥75%. This study compares the risk of interval or higher stage invasive cancers among postmenopausal women screened annually vs biennially by age and estrogen use. Methods: A retrospective design identified 4247 invasive breast cancers diagnosed among concurrent cohorts of women 50-74 screened in the OBSP with digital mammography between 2011 and 2014, followed until 2016. Polytomous logistic regression estimated the risk of interval or higher stage breast cancers by age and estrogen use between women screened annually because of first-degree relative with breast or ovarian cancer or personal history of ovarian cancer, or mammographic density ≥75%, and those screened biennially. Results: The risk of interval vs screen-detected cancers was significantly reduced in women screened annually for family/personal history (OR=.64; 95%CI:0.51-.80), particularly those 60-74 years (OR=.59; 95%CI:0.45-.77) or not currently using estrogen (OR=.66; 95%CI:0.52-.83) compared to those screened biennially. The risk of stage II-IV vs stage I tumors was also lower in women 60-74 years screened annually for family/personal history (OR=.79; 95%CI:0.64-.97) and in those screened annually for mammographic density ≥75% currently using estrogen (OR=.51; 95%CI:0.26-1.01) compared to women screened biennially. Conclusion: Postmenopausal women at increased risk screened annually had equivalent or reduced risks of interval or higher stage invasive breast cancers than those screened biennially, further supporting risk-based screening in this population.

Inhaled corticosteroid prescriptions in the ED for recurrent asthma using IT clinical decision support: revisit after cessation of an incentive program.

INTRODUCTION: The objective of this study was to assess whether inhaled corticosteroid (ICS) prescription rates for patients with poorly controlled asthma presenting to the emergency department (ED) remained high with a clinical support system in place, after a financial incentive program ended. This study is the second phase of a previous study done at our institution. The first phase demonstrated that the introduction of an electronic alert system advising providers to prescribe ICS to patients with poorly controlled asthma, along with a financial incentive, increased ICS prescription rates from 2% to 77%. Clinical support systems are necessary to improve control for patients with asthma, as prescribing ICS in the ED has not previously been standard of care. METHODS: This retrospective study identified 96 eligible patients during the study period of January 1, 2019 to December 31, 2019. Subjects included patients aged 4-18 with at least two ED visits for asthma within 365 days and no recent ICS prescription. For subjects meeting these criteria, an electronic alert activated, advising the provider to prescribe ICS. RESULTS: ICS prescription rate without the incentive remained high at 0.74 (0.59, 0.86) and was not significantly different than the rate with the incentive of 0.77 (0.65, 0.87), with p value 0.82. No significant differences were detected in baseline characteristics between patients discharged with and without an ICS prescription. CONCLUSIONS: This study confirmed that an electronic alert advising ICS prescription in the ED for patients with recurrent asthma visits is effective, even without a financial incentive.

Pediatric Emergency Department Return Visits Within 72 Hours: Caregivers' Motives and Analysis of Ethnic and Primary Language Disparities.

OBJECTIVES: In the United States, approximately 2.2% to 5% of children discharged from the emergency department (ED) return within 72 hours. There is limited literature examining caregivers' reasons for return to the ED, and none among Hispanics and Spanish-speaking caregivers. We sought to examine why caregivers of pediatric patients return to the ED within 72 hours of a prior ED visit, and assess roles of ethnicity and primary language. METHODS: A previously validated survey was prospectively administered to caregivers returning to the ED within 72 hours of discharge at a freestanding, tertiary care, children's hospital over a 7-month period. Reasons for return to the ED, previous ED discharge processes, and events since discharge were summarized according to Hispanic ethnicity, and English or Spanish language preference, and compared using the Fisher exact test. RESULTS: Among 499 caregiver surveys analyzed, caregivers returned mostly because of no symptom improvement (57.5%) and worsening condition (35.5%), with no statistically significant differences between Hispanic/non-Hispanic ethnicity, or English/Spanish preference. Most (85.2%) caregivers recalled reasons to return to the ED. Recall of expected duration until symptom improvement was significantly higher among Hispanic (60.4%) versus non-Hispanic (52.1%) (P = 0.003), and for Spanish- (68.9%) versus English-speaking (54.6%) (P = 0.04), caregivers. CONCLUSIONS: Most caregivers returned to the ED because their child's condition was not better or had worsened. Ethnicity and language were not associated with variations in reasons for return. Non-Hispanic and English-speaking caregivers were less likely to recall being informed of time to improvement and may require additional intervention.

Lower Maternal Chronic Physiological Stress and Better Child Behavior at 18 Months: Follow-Up of a Cluster Randomized Trial of Neonatal Intensive Care Unit Family Integrated Care.

OBJECTIVE: To assess whether Family Integrated Care (FICare) in the neonatal intensive care unit improves maternal chronic physiological stress and child behavior at 18 months of corrected age for infants born preterm. STUDY DESIGN: Follow-up of a multicenter, prospective cluster-randomized controlled trial comparing FICare and standard care of children born at <33 weeks of gestation and parents, stratified by tertiary neonatal intensive care units, across Canada. Primary outcomes at 18 months of corrected age were maternal stress hormones (cortisol, ie, hair cumulative cortisol [HCC], dehydroepiandrosterone [DHEA]) assayed from hair samples. Secondary outcomes included maternal reports of parenting stress, child behaviors (Internalizing, Externalizing, Dysregulation), and observer-rated caregiving behaviors. Outcomes were analyzed using multilevel modeling. RESULTS: We included 126 mother-child dyads from 12 sites (6 FICare sites, n = 83; 6 standard care sites, n = 43). FICare intervention significantly lowered maternal physiological stress as indicated by HCC (B = -0.22 [-0.41, -0.04]) and cortisol/DHEA ratio (B = -0.25 [-0.48, -0.02]), but not DHEA (B = 0.01 [-0.11, 0.14]). Enrollment in FICare led to lower child Internalizing (B = -0.93 [-2.33, 0.02]) and Externalizing behavior T scores (B = -0.91 [-2.25, -0.01]) via improvements to maternal HCC (mediation). FICare buffered the negative effects of high maternal HCC on child Dysregulation T scores (B = -11.40 [-23.01, 0.21]; moderation). For mothers reporting high parenting stress at 18 months, FICare was related to lower Dysregulation T scores via maternal HCC; moderated mediation = -0.17 (-0.41, -0.01). CONCLUSIONS: FICare has long-term beneficial effects for mother and child, attenuating maternal chronic physiological stress, and improving child behavior in toddlerhood. CLINICAL TRIAL REGISTRATION: NCT01852695.

Stoss therapy is safe for treatment of vitamin D deficiency in pediatric patients undergoing HSCT.

Vitamin D deficiency remains common among pediatric patients undergoing hematopoietic stem cell transplant (HSCT) despite both aggressive and standard of care strategies. This study examined the safety and efficacy of single high-dose oral vitamin D therapy (Stoss therapy) for treatment of vitamin D deficiency in HSCT recipients. Patients ages 1-21 years presenting for HSCT were randomized to receive either Stoss regimen plus weekly/daily supplementation or standard of care, per US Endocrine Society guidelines. Among the total 48 subjects, 22 (46%) were randomized to Stoss and 26 (54%) to control arms. Baseline 25-hydroxyvitamin D (25-OHD) levels were insufficient/deficient in total of 34 (71%) patients, without difference between treatment groups. The Stoss regimen was well tolerated and no toxicity was observed. At Day +30, mean 25-OHD levels were significantly higher (P = 0.04) with Stoss (42.3 ± 12 µg/l) compared to controls (35.6 ± 14.3 µg/l), and a higher proportion of Stoss patients had adequate vitamin D levels than controls (85% vs 65%). Stoss therapy is a safe and efficacious treatment option for vitamin D deficiency in children undergoing HSCT and may achieve sufficient levels more rapidly than standard of care. This trial was registered at www.clinicaltrials.gov as NCT03176849.

Metformin as Adjunctive Therapy for Pediatric Patients With Hidradenitis Suppurativa.

BACKGROUND: Hidradenitis suppurativa (HS) is a chronic inflammatory disorder seen in adolescents and adults characterized by abscesses, sinus tracts and scarring, typically affecting intertriginous skin. Treatments often provide suboptimal control of the disease, and there are limited reports of therapies utilized in the pediatric population. There are no published guidelines or consensus for the treatment of pediatric HS. PURPOSE: To evaluate the clinical efficacy and safety of metformin as adjunctive treatment in adolescent patients with HS who have not responded to standard therapies at a single institution. RESULTS: Retrospective chart review identified 16 pediatric patients treated with metformin as adjunctive therapy for HS. Baseline scores were Hurley 1 in eleven (69%) and Hurley 2 in five (31%) patients. Follow-up visit data showed six (67%) patients were Hurley 1 and three (33%) patients were Hurley 2; five patients showed improvement on metformin with decreased frequency of flares, and five patients had no improvement. Six patients were lost to follow up or data was not available. Two patients discontinued metformin therapy due to side effects, including gastrointestinal distress and mood changes; the third patient discontinued due to lack of improvement. Two patients had mildly elevated liver transaminases prior to metformin initiation which improved while on metformin therapy. DISCUSSION: For some pediatric patients, metformin as an adjunctive therapy may help improve control of HS with minimal side effects. Adequately designed and controlled studies are needed to further evaluate the role of metformin, and efficacy, tolerability and safety in the pediatric HS patients.

Family Integrated Care (FICare): Positive impact on behavioural outcomes at 18 months.

BACKGROUND: Children born very preterm demonstrate behavioural challenges due to clinical factors, exposure to the high stress environment of intensive care, and separation from parents during neonatal hospitalization at a critical stage in development. Family Integrated Care (FICare) significantly reduced parent stress and anxiety, and improved neonatal outcomes. AIMS: To examine the impact of FICare on behavioural outcomes at 18-21 months corrected age (CA), and assess possible mediation through parenting or infant growth. STUDY DESIGN AND METHODS: A prospective cohort study enrolling infants under 33 weeks gestation and parents from the FICare cluster randomized controlled trial. Primary outcome was behaviour assessed by the Infant Toddler Social Emotional Assessment (ITSEA). Parent child variables were measured with the Nursing Child Assessment Satellite Training (NCAST), Parenting Stress Index (PSI) and infant growth. RESULTS: Subjects included 123 FICare infants and 62 standard care controls evaluated at 18-21 months CA. FICare infants demonstrated lower ITSEA Dysregulation, indicating better self-regulation skills, compared with the control group (T-score 41.7 vs 46.6, p < 0.01). At 12 months CA, the NCAST Child subtotal score was higher and the PSI-Child Domain score was lower in FICare infants than non-FICare infants. The PSI-Child domain was identified as a possible mediator of FICare on child behaviour (mediation effect 1.28, -2.96-0.02, p = 0.044). CONCLUSION: FICare in the NICU has a sustained effect on child behaviour, improving self-regulation at 18-21 months CA.
