Manuscripts, Articles, Book Chapters and Other Papers

Influenza C virus (ICV) is an orthomyxovirus related to influenza A and B, yet due to few commercial assays, epidemiologic studies may underestimate incidence of ICV infection and disease. We describe the epidemiology and characteristics of ICV within the New Vaccine Surveillance Network (NVSN), a Centers for Disease Control and Prevention (CDC)-led network that conducts population-based surveillance for pediatric acute respiratory illness (ARI). Nasal or/combined throat swabs were collected from emergency department (ED) or inpatient ARI cases, or healthy controls, between 12/05/2016-10/31/2019 and tested by molecular assays for ICV and other respiratory viruses. Parent surveys and chart review were used …

BACKGROUND: Patients treated for cancer have a higher incidence of focal liver lesions than the general population and there is often concern for a malignant etiology. This can result in patient, caregiver and physician anxiety and is managed by a "wait and watch" approach, or immediate additional imaging, or biopsy, depending on the degree of clinical concern. Because it is a low-cost, easily accessible, radiation and sedation free modality, we investigated the value of contrast enhanced ultrasound (CEUS) to accurately distinguish benign from malignant liver lesions in patients treated for childhood malignancies.

METHODS: We performed an IRB approved retrospective study …

INTRODUCTION: Chronic inflammation of the gastrointestinal tissues underlies gastrointestinal inflammatory disorders, leading to tissue damage and a constellation of painful and debilitating symptoms. These disorders include inflammatory bowel diseases (Crohn's disease and ulcerative colitis), and eosinophilic disorders (eosinophilic esophagitis and eosinophilic duodenitis). Gastrointestinal inflammatory disorders can often present with overlapping symptoms necessitating the use of invasive procedures to give an accurate diagnosis.

METHODS: This study used peripheral blood mononuclear cells from individuals with Crohn's disease, ulcerative colitis, eosinophilic esophagitis, and eosinophilic duodenitis to better understand the alterations to the transcriptome of individuals with these diseases and identify potential markers of …

Management Of Diabetic Ketoacidosis In Children: Does Early Insulin Glargine Help Improve Outcomes?, Rebecca Ohman-Hanson, G Todd Alonso, Laura Pyle, Ryan Mcdonough, Mark A. Clements

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Rebound hyperglycemia following the resolution of diabetic ketoacidosis (DKA) is common in pediatric patients with type 1 diabetes, increasing the risk of recurrent DKA and complicating the transition to subcutaneous insulin. Multiple studies suggest that early administration of long-acting insulin analogs during DKA management safely improves this transition.

OBJECTIVE: This study aimed to determine whether early insulin glargine administration in children with DKA prevents rebound hyperglycemia and recurrent ketosis without increasing the rate of hypoglycemia or hypokalemia.

METHODS: Patients agedChildren's Mercy Kansas City between October 2012 and October 2016 were reviewed. They were categorized as Early (>4 h …

Digital Gaming And Exercise Among Youth With Type 1 Diabetes: Cross-Sectional Analysis Of Data From The Type 1 Diabetes Exercise Initiative Pediatric Study., Susana R. Patton, Robin L. Gal, Simon Bergford, Peter Calhoun, Mark A. Clements, Jennifer L. Sherr, Michael C. Riddell

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Regular physical activity and exercise are fundamental components of a healthy lifestyle for youth living with type 1 diabetes (T1D). Yet, few youth living with T1D achieve the daily minimum recommended levels of physical activity. For all youth, regardless of their disease status, minutes of physical activity compete with other daily activities, including digital gaming. There is an emerging area of research exploring whether digital games could be displacing other physical activities and exercise among youth, though, to date, no studies have examined this question in the context of youth living with T1D.

OBJECTIVE: We examined characteristics of digital …

Pediatric Beta Blocker Therapy: A Comprehensive Review Of Development And Genetic Variation To Guide Precision-Based Therapy In Children, Adolescents, And Young Adults., Mollie Walton, Jonathan B. Wagner

Manuscripts, Articles, Book Chapters and Other Papers

Beta adrenergic receptor antagonists, known as beta blockers, are one of the most prescribed medications in both pediatric and adult cardiology. Unfortunately, most of these agents utilized in the pediatric clinical setting are prescribed off-label. Despite regulatory efforts aimed at increasing pediatric drug labeling, a majority of pediatric cardiovascular drug agents continue to lack pediatric-specific data to inform precision dosing for children, adolescents, and young adults. Adding to this complexity is the contribution of development (ontogeny) and genetic variation towards the variability in drug disposition and response. In the absence of current prospective trials, the purpose of this comprehensive review …

BACKGROUND: Our previous study established a 2-dose regimen of high-dose trivalent influenza vaccine (HD-TIV) to be immunogenically superior compared to a 2-dose regimen of standard-dose quadrivalent influenza vaccine (SD-QIV) in pediatric allogeneic hematopoietic cell transplant (HCT) recipients. However, the durability of immunogenicity and the role of time post-HCT at immunization as an effect modifier are unknown.

METHODS: This phase II, multi-center, double-blinded, randomized controlled trial compared HD-TIV to SD-QIV in children 3-17 years old who were 3-35 months post-allogeneic HCT, with each formulation administered twice, 28-42 days apart. Hemagglutination inhibition (HAI) titers were measured at baseline, 28-42 days following each …

We explored the association between macronutrient intake and postprandial glucose variability in a large sample of youth living with T1D and consuming free-living meals. In the Type 1 Diabetes Exercise Initiative Pediatric (T1DEXIP) Study, youth took photographs before and after their meals on 3 days during a 10 day observation period. We used the remote food photograph method to obtain the macronutrient content of youth's meals. We also collected physical activity, continuous glucose monitoring, and insulin use data. We measured glycemic variability using standard deviation (SD) and coefficient of variation (CV) of glucose for up to 3 h after meals. …
