Item A co-designed, community-based intensive health behavior intervention promotes participation and engagement in youth with risk factors for type 2 diabetes(Frontiers Media, 2023-12-01) Pike, Julie M.; Haberlin-Pittz, Kathryn M.; Alharbi, Basmah S.; Perkins, Susan M.; Hannon, Tamara S.; Pediatrics, School of MedicineBackground: Obesity among youth (children and adolescents) is associated with increased risk for youth-onset type 2 diabetes. Lifestyle change can delay or prevent the development of type 2 diabetes, yet real-world implementation of health behavior recommendations is challenging. We previously engaged youth with risk factors for type 2 diabetes, their caregivers, and professionals in a human-centered design study to co-design a lifestyle change program. Here we report the outcomes for this 16-week co-designed lifestyle change program for youth at risk for T2D and their caregivers. Research design and methods: This single-arm family-based cohort study included youth aged 7-18 years, with BMI ≥85th percentile (overweight or obese) and at least one additional risk factor for type 2 diabetes, and their caregivers. Clinical (BMI, HbA1c), self-reported physical activity, and quality of life outcomes were evaluated at baseline (B), post-intervention (M4), and 1 year (M12) following the intervention. Results: Seventy-eight youth (mean age 12.4 ± 2.7y, 67% female, 37.8% white) and 65 caregivers were included in the data analysis. Youth baseline BMI z-scores (2.26 ± 0.47) and HbA1c (5.3 ± 0.3) were unchanged at follow up time points [BMI z-scores M4 (2.25 ± 0.52), M12 (2.16 ± 0.58), p-value 0.46], [HbA1c M4 (5.3 ± 0.3), M12 (5.2 ± 0.3), p-value (0.04)]. Youth reported increased physical activity at M4 (p = 0.004), but not at M12. Youth quality of life scores increased at M12 (p=0.01). Families who attended at least one session (n=41) attended an average of 9 out of 16 sessions, and 37 percent of families attended 13 or more sessions. Conclusion: A co-designed, community-based lifestyle intervention promotes increased physical activity, improved quality of life, maintenance of BMI z-scores and HbA1c, and engagement in youth with risk factors for T2D.Item A Psychometric Evaluation of the NIH Toolbox Fluid Cognition Tests Adapted for Swahili and Dholuo Languages in Kenyan Children and Adolescents(Cambridge University Press, 2023) McHenry, Megan S.; Roose, Anna; Abuonji, Emily; Nyalumbe, Mark; Ayuku, David; Ayodo, George; Tran, Tuan M.; Kaat, Aaron J.; Pediatrics, School of MedicineObjective: Our objective was to evaluate the psychometric properties of the culturally adapted NIH Toolbox African Languages® when used in Swahili and Dholuo-speaking children in western Kenya. Method: Swahili-speaking participants were recruited from Eldoret and Dholuo-speaking participants from Ajigo; all were <14 years of age and enrolled in primary school. Participants completed a demographics questionnaire and five fluid cognition tests of the NIH Toolbox® African Languages program, including Flanker, Dimensional Change Card Sort (DCCS), Picture Sequence Memory, Pattern Comparison, and List Sorting tests. Statistical analyses examined aspects of reliability, including internal consistency (in both languages) and test-retest reliability (in Dholuo only). Results: Participants included 479 children (n = 239, Swahili-speaking; n = 240, Dholuo-speaking). Generally, the tests had acceptable psychometric properties for research use within Swahili- and Dholuo-speaking populations (mean age = 10.5; SD = 2.3). Issues related to shape identification and accuracy over speed limited the utility of DCCS for many participants, with approximately 25% of children unable to match based on shape. These cultural differences affected outcomes of reliability testing among the Dholuo-speaking cohort, where accuracy improved across all five tests, including speed. Conclusions: There is preliminary evidence that the NIH Toolbox ® African Languages potentially offers a valid assessment of development and performance using tests of fluid cognition in Swahili and Dholuo among research settings. With piloting underway across other diverse settings, future research should gather additional evidence on the clinical utility and acceptability of these tests, specifically through the establishment of norming data among Kenyan regions and evaluating these psychometric properties.Item A Quality Improvement Initiative to Reduce Unnecessary Screening Chest Radiographs in a Pediatric ICU(American Association of Respiratory Care, 2023) Malin, Stefan W.; Maue, Danielle K.; Cater, Daniel T.; Ealy, Aimee R.; McCallister, Anne E.; Valentine, Kevin M.; Abu-Sultaneh, Samer M.; Pediatrics, School of MedicineBackground: The Critical Care Societies Collaborative included not ordering diagnostic tests at regular intervals as one of their Choosing Wisely initiatives. A reduction in unnecessary chest radiographs (CXRs) can help reduce exposure to radiation and eliminate health care waste. We aimed to reduce daily screening CXRs in a pediatric ICU (PICU) by 20% from baseline within 4 months of implementation of CXR criteria. Methods: All intubated patients in the PICU were included in this quality improvement project. Patients with tracheostomies were excluded. We developed criteria delineating which patients were most likely to benefit from a daily screening CXR, and these criteria were discussed for each patient on rounds. Patients on extracorporeal membrane oxygenation, on high-frequency oscillatory ventilation, or on high support on conventional mechanical ventilation were included as needing a daily screening CXR. We tracked the percentage of intubated subjects receiving a screening CXR as an outcome measure. Unplanned extubations and the number of non-screening CXRs per intubated subject were followed as balancing measures. Results: The percentage of intubated subjects receiving a daily screening CXR was reduced from 79% to 31%. There was no increase in frequency of unplanned extubations or number of non-screening CXRs. With an estimated subject charge of roughly $270 and hospital cost of $54 per CXR, this project led to an estimated $300,000 in patient charge savings and $60,000 in hospital cost savings. Conclusions: Adopting criteria to delineate which patients are most likely to benefit from screening CXRs can lead to a reduction in the percentage of intubated patients receiving screening CXRs without appearing to increase harm.Item Acute Kidney Injury Associated With Urinary Stone Disease in Children and Young Adults Presenting to a Pediatric Emergency Department(Frontiers Media, 2020-11-30) Farris, Nicholas; Raina, Rupesh; Tibrewal, Abhishek; Brown, Miraides; Colvis, Maria; Schwaderer, Andrew; Kusumi, Kirsten; Pediatrics, School of MedicineBackground: Acute kidney injury (AKI) due to urinary stone disease (USD) is rare in adults; AKI rates in children with USD may be higher, and emerging data links stones to chronic kidney disease (CKD) development in adults. Methods: This study is a retrospective analysis of USD patients at a single pediatric hospital system's emergency department (ED). Patients were initially identified by USD ICD codes; USD was then confirmed by imaging or physician documentation; patients had to have baseline creatinine (Cr) and Cr in the ED for comparison to be included. AKI was defined by Kidney Disease: Improving Global Outcomes (KDIGO), Acute Kidney Injury Network (AKIN), and Pediatric Risk, Injury, Failure, Loss, End Stage (pRIFLE). Results: Of the 589 total visits, 264/589 (45%) had data to evaluate for AKI, 23% were AKI(+) and 77% were AKI(-). pRIFLE was most common (82%) and 18% were only positive by AKIN/KDIGO. AKI(+) were more likely to be younger (16.7 vs. 17.4 years, p = 0.046) and more likely to present with vomiting {odds ratio [OR] [95% confidence interval (CI)]: 2.4 [1.4-4.3], p = 0.002}; also, the proportion of AKI(+) was significantly higher in <18 vs. ≥18 years [26.9 vs. 15.5%, p = 0.032, OR (95% CI): 2.0 (1.1-3.9)]. Urinary tract infection (UTI) and obstruction rates were similar between groups. AKI(+) patients had a significant OR <1 suggesting less risk of receiving non-steroidal anti-inflammatory drugs (NSAIDs); however, 51% of them did receive NSAIDs during their ED encounter. AKI(+) patients were more likely to require admission to the hospital (53 vs. 32%, p = 0.001). Conclusion: We have demonstrated a novel association between USD-induced renal colic and AKI in a group of young adults and children. AKI(+) patients were younger and were more likely to present with vomiting. AKI(+) patients did not have higher rates of obstruction or UTI, and 51% of AKI(+) received NSAIDs.Item Adherence to pediatric diabetic ketoacidosis guidelines by community emergency departments' providers(Springer, 2017-12) Zee-Cheng, Janine E.; Webber, Emily C.; Abu-Sultaneh, Samer; Department of Pediatrics, IU School of MedicineBackground: Diabetic ketoacidosis (DKA) is a common presentation of type I diabetes mellitus to the emergency departments. Most children with DKA are initially managed in community emergency departments where providers may not have easy access to educational resources or pediatric-specific guidelines and protocols that are readily available at pediatric academic medical centers. The aim of this study is to evaluate adherence of community emergency departments in the state of Indiana to the pediatric DKA guidelines. Methods: We performed a retrospective chart review of patients, age 18 years of age or under, admitted to the pediatric intensive care unit with a diagnosis of DKA. Results: A total of 100 patients were included in the analysis. Thirty-seven percent of patients with DKA were managed according to all six guideline parameters. Only 39% of patients received the recommended hourly blood glucose checks. Thirty percent of patients received intravenous insulin bolus, which is not recommended. Conclusions: Non-adherence to pediatric DKA guidelines still exists in the state of Indiana. Further, larger studies are needed to reveal the etiology of non-adherence to pediatric DKA guidelines and strategies to improve that adherence.Item Age-Related Changes in MicroRNA Expression and Pharmacogenes in Human Liver(Wiley, 2015-08) Burgess, Kimberly S.; Philips, Santosh; Benson, Eric A.; Desta, Zeruesenay; Gaedigk, Andrea; Gaedigk, Roger; Segar, Matthew W.; Liu, Yunlong; Skaar, Todd C.; Department of Pharmacology and Toxicology, IU School of MedicineDevelopmental changes in the liver can significantly impact drug disposition. Due to the emergence of microRNAs (miRNAs) as important regulators of drug disposition gene expression, we studied age-dependent changes in miRNA expression. Expression of 533 miRNAs was measured in 90 human liver tissues (fetal, pediatric [1-17 years], and adult [28-80 years]; n = 30 each). In all, 114 miRNAs were upregulated and 72 were downregulated from fetal to pediatric, and 2 and 3, respectively, from pediatric to adult. Among the developmentally changing miRNAs, 99 miRNA-mRNA interactions were predicted or experimentally validated (e.g., hsa-miR-125b-5p-CYP1A1; hsa-miR-34a-5p-HNF4A). In human liver samples (n = 10 each), analyzed by RNA-sequencing, significant negative correlations were observed between the expression of >1,000 miRNAs and mRNAs of drug disposition and regulatory genes. Our data suggest a mechanism for the marked changes in hepatic gene expression between the fetal and pediatric developmental periods, and support a role for these age-dependent miRNAs in regulating drug disposition.Item Assessment of Pediatric Chemotherapy-Induced Peripheral Neuropathy Using a New Patient-Reported Outcome Measure: The P-CIN(Sage, 2021) Smith, Ellen M. Lavoie; Kuisell, Clare; Kanzawa-Lee, Grace; Bridges, Celia M.; Cho, Youmin; Swets, Jenna; Renbarger, Jamie L.; Gilchrist, Laura S.; Medicine, School of MedicineBackground: Chemotherapy-induced peripheral neuropathy (CIPN) is commonly experienced by children receiving neurotoxic chemotherapy. No validated pediatric CIPN patient-reported outcome (PRO) measures exist. Purpose: To test sensitivity, internal consistency reliability, content and convergent validity, and feasibility of the Pediatric Chemotherapy-Induced Neuropathy (P-CIN), an electronic PRO measure for assessing CIPN in children who received neurotoxic chemotherapy. Method: Five experts evaluated content validity of the 14-item P-CIN. Children 5 to 17 years old with CIPN (N = 79) completed the P-CIN via tablet computer; a subset (n = 26) also underwent neurological examinations using the Pediatric-Modified Total Neuropathy Score. Following preliminary analyses, one item was deleted and three others modified. The revised P-CIN was retested with patients (n = 6) who also completed the Bruininks-Oseretsky Test of Motor Proficiency motor function assessment. Means, item response ranges, standard deviations, content validity indexes, Cronbach's alphas, and correlation coefficients were calculated. Results: Mean participant age was 11.25 (SD = 4.0) years. Most had acute leukemia (62.5%) and received vincristine (98.7%). Content validity index coefficients ranged from .80 to 1.0 (p = .05). For 9 of 14 items, responses ranged from 0 to 4 or 5; response ranges for toe numbness, pick up a coin, and three of four pain items were 0 to 3. After deleting one item, Cronbach's alpha coefficient was .83. P-CIN scores were strongly associated with Pediatric-Modified Total Neuropathy Score (r = .52, p < .01) and Bruininks-Oseretsky Test of Motor Proficiency (r = -.83, p = .04) scores. Sixty-eight percent of children 6 to 17 years old completed P-CIN independently. Discussion: Preliminary evidence suggests that the 13-item P-CIN is internally consistent, is valid, and can be completed independently by children ≥ 6 years. However, we recommend additional testing.Item Barriers to Upper Extremity Reconstruction for Patients With Cerebral Palsy(Sage, 2022) Loewenstein, Scott N.; Angulo-Parker, Francisco; Timsina, Lava; Adkinson, Joshua; Surgery, School of MedicineBackground: Reconstructive surgery for upper extremity manifestations of cerebral palsy (CP) has been demonstrated to be safe and effective, yet many potential candidates are never evaluated for surgery. The purpose of this study was to determine barriers to upper extremity reconstruction for patients with CP in a cohort of upper extremity surgeons and nonsurgeons. Methods: We sent a questionnaire to 4167 surgeons and nonsurgeon physicians, aggregated responses, and analyzed for differences in perceptions regarding surgical efficacy, patient candidacy for surgery, compliance with rehabilitation, remuneration, complexity of care, and physician comfort providing care. Results: Surgeons and nonsurgeons did not agree on the literature support of surgical efficacy (73% vs 35% agree or strongly agree, respectively). Both surgeons and nonsurgeons felt that many potential candidates exist, yet there was variability in their confidence in identifying them. Most surgeons (59%) and nonsurgeons (61%) felt comfortable performing surgery and directing the associated rehabilitation, respectively. Neither group reported that patient compliance, access to rehabilitation services, and available financial resources were a major barrier, but surgeons were more likely than nonsurgeons to feel that remuneration for services was inadequate (37% vs 13%). Both groups agreed that surgical treatments are complex and should be performed in the setting of a multidisciplinary team. Conclusions: Surgeons and nonsurgeons differ in their views regarding upper extremity reconstructive surgery for CP. Barriers to reconstruction may be addressed by performing higher level research, implementing multispecialty educational outreach, developing objective referral criteria, increasing surgical remuneration, improving access to trained upper extremity surgeons, and implementing multidisciplinary CP clinics.Item Bedside lung ultrasound for the diagnosis of pneumonia in children presenting to an emergency department in a resource-limited setting(BMC, 2023-01-09) Amatya, Yogendra; Russell, Frances M.; Rijal, Suraj; Adhikari, Sunil; Nti, Benjamin; House, Darlene R.; Emergency Medicine, School of MedicineBackground: Lung ultrasound (LUS) is an effective tool for diagnosing pneumonia; however, this has not been well studied in resource-limited settings where pneumonia is the leading cause of death in children under 5 years of age. Objective: The objective of this study was to evaluate the diagnostic accuracy of bedside LUS for diagnosis of pneumonia in children presenting to an emergency department (ED) in a resource-limited setting. Methods: This was a prospective cross-sectional study of children presenting to an ED with respiratory complaints conducted in Nepal. We included all children under 5 years of age with cough, fever, or difficulty breathing who received a chest radiograph. A bedside LUS was performed and interpreted by the treating clinician on all children prior to chest radiograph. The criterion standard was radiographic pneumonia, diagnosed by a panel of radiologists using the Chest Radiography in Epidemiological Studies methodology. The primary outcome was sensitivity and specificity of LUS for the diagnosis of pneumonia. All LUS images were later reviewed and interpreted by a blinded expert sonographer. Results: Three hundred and sixty-six children were enrolled in the study. The median age was 16.5 months (IQR 22) and 57.3% were male. Eighty-four patients (23%) were diagnosed with pneumonia by chest X-ray. Sensitivity, specificity, positive and negative likelihood ratios for clinician's LUS interpretation was 89.3% (95% CI 81-95), 86.1% (95%CI 82-90), 6.4, and 0.12 respectively. LUS demonstrated good diagnostic accuracy for pneumonia with an area under the curve of 0.88 (95% CI 0.83-0.92). Interrater agreement between clinician and expert ultrasound interpretation was excellent (k = 0.85). Conclusion: Bedside LUS when used by ED clinicians had good accuracy for diagnosis of pneumonia in children in a resource-limited setting.Item Blood Pressure Outcomes in NICU-Admitted Infants with Neonatal Hypertension: A Pediatric Nephrology Research Consortium Study(Elsevier, 2024) Xiao, Nianzhou; Starr, Michelle; Stolfi, Adrienne; Hamdani, Gilad; Hashmat, Shireen; Kiessling, Stefan G.; Sethna, Christina; Kallash, Mahmoud; Matloff, Robyn; Woroniecki, Robert; Sanderson, Keia; Yamaguchi, Ikuyo; Cha, Stephen D.; Semanik, Michael G.; Chanchlani, Rahul; Flynn, Joseph T.; Mitsnefes, Mark; Pediatrics, School of MedicineObjective: To describe the blood pressure outcomes of infants admitted to the neonatal intensive care unit (NICU) with idiopathic (nonsecondary) hypertension (HTN) who were discharged on antihypertensive therapy. Study design: Retrospective, multicenter study of 14 centers within the Pediatric Nephrology Research Consortium. We included all infants with a diagnosis of idiopathic HTN discharged from the NICU on antihypertensive treatment. The primary outcome was time to discontinuation of antihypertensive therapy, grouped into (≤6 months, >6 months to 1 year, and >1 year). Comparisons between groups were made with χ2 tests, Fisher's exact tests, and ANOVA. Results: Data from 118 infants (66% male) were included. Calcium channel blockers were the most prescribed class of antihypertensives (56%) in the cohort. The percentages remaining on antihypertensives after NICU discharge were 60% at 6 months, 26% at 1 year, and 7% at 2 years. Antenatal steroid treatment was associated with decreased likelihood of antihypertensive therapy >1 year after discharge. Conclusions: This multicenter study reports that most infants admitted to the NICU diagnosed with idiopathic HTN will discontinue antihypertensive treatment by 2 years after NICU discharge. These data provide important insights into the outcome of neonatal HTN, but should be confirmed prospectively.
