Fcγ receptors (FcγRs) are membrane-bound glycoproteins that bind to the fragment crystallizable (Fc) constant regions of IgG antibodies. Interactions between IgG immune complexes and FcγRs can initiate signal transduction that mediates important components of the immune response including activation of immune cells for clearance of opsonized pathogens or infected host cells. In humans, many studies have identified associations between FcγR gene polymorphisms and risk of infection, or progression of disease, suggesting a gene-level impact on FcγR-dependent immune responses. Rhesus macaques are an important translational model for most human health interventions, yet little is known about the breadth of rhesus macaque …

A Pilot Intervention Combining Assessment And Feedback With Communication Training And Behavioral Nudges To Increase Hpv Vaccine Uptake., Andrea Bradley-Ewing, Brian R. Lee, Jason N. Doctor, Georgann Meredith, Kathy Goggin, Angela Myers

Manuscripts, Articles, Book Chapters and Other Papers

Human papillomavirus (HPV) causes >40,000 cancer diagnoses each year, yet vaccination rates remain low because widespread implementation of strategies to increase vaccinations has not occurred. Behavioral nudges have demonstrated efficacy in improving uptake of desired behaviors in health care settings but have not been tested for increasing HPV vaccinations. We assessed the impact of an intervention combining behavioral nudges with other proven strategies (i.e., assessment and feedback, provider communication training) on HPV vaccination rates and parental satisfaction in four Midwestern pediatric, outpatient practices. Practices were randomly assigned to receive either assessment and feedback or assessment and feedback combined with vaccine …

Manuscripts, Articles, Book Chapters and Other Papers

The New Vaccine Surveillance Network (NVSN) is a prospective, active, population-based surveillance platform that enrolls children with acute respiratory illnesses (ARIs) at seven pediatric medical centers. ARIs are caused by respiratory viruses including influenza virus, respiratory syncytial virus (RSV), human metapneumovirus (HMPV), human parainfluenza viruses (HPIVs), and most recently SARS-CoV-2 (the virus that causes COVID-19), which result in morbidity among infants and young children (1-6). NVSN estimates the incidence of pathogen-specific pediatric ARIs and collects clinical data (e.g., underlying medical conditions and vaccination status) to assess risk factors for severe disease and calculate influenza and COVID-19 vaccine effectiveness. Current NVSN …

Stewardship Opportunities For Cervical Lymphadenitis And Deep Neck Space Infections, Aaron Shaw, Brian R. Lee, Lauren Kazmaier, Emily Baker, Tina Dao, Sandra Arnold, Angela Myers

Posters

Background: Cervical lymphadenitis (LAD) and deep neck space abscesses (DNSA) are common pediatric infections caused by similar bacteria. We sought to determine differences in presentation, diagnosis, and treatment between LAD and DNSA to identify antimicrobial and diagnostic stewardship opportunities. Methods: Charts were obtained using ICD9/10 codes for retropharyngeal and parapharyngeal abscessed (DNSA), and LAD between 1/1/10-12/31/20 from two pediatric centers. 1981 charts were identified. Charts were excluded if the diagnosis was not a bacterial infection (e.g. Kawasaki disease), if the LAD was not in the neck, or if caused by less common bacteria (e.g. tuberculosis). Data on presenting signs, symptoms, …

Piloting A Systems Level Intervention To Improve Cervical Cancer Screening, Treatment And Follow Up In Kenya., Natabhona M. Mabachi, Catherine Wexler, Harshdeep Acharya, May Maloba, Kevin Oyowe, Kathy Goggin, Sarah Finocchario-Kessler

Manuscripts, Articles, Book Chapters and Other Papers

Although preventable, Cervical Cancer (CC) is the leading cause of cancer deaths among women in Sub-Saharan Africa with the highest incidence in East Africa. Kenyan guidelines recommend an immediate screen and treat approach using either Pap smear or visual screening methods. However, system (e.g., inadequate infrastructure, weak treatment, referral and tracking systems) and patient (e.g., stigma, limited accessibility, finance) barriers to comprehensive country wide screening continue to exist creating gaps in the pathways of care. These gaps result in low rates of eligible women being screened for CC and a high loss to follow up rate for treatment. The long-term …

Before the introduction of vaccines, group A rotaviruses (RVA) were the leading cause of acute gastroenteritis in children worldwide. The National Rotavirus Strain Surveillance System (NRSSS) was established in 1996 by the Centers for Disease Control and Prevention (CDC) to perform passive RVA surveillance in the USA. We report the distribution of RVA genotypes collected through NRSSS during the 2009-2016 RVA seasons and retrospectively examine the genotypes detected through the NRSSS since 1996. During the 2009-2016 RVA seasons, 2134 RVA-positive fecal specimens were sent to the CDC for analysis of the VP7 and VP4 genes by RT-PCR genotyping assays and …

Manuscripts, Articles, Book Chapters and Other Papers

Background: It is estimated that over 60% of adults with asthma have uncontrolled symptoms, representing a substantial health and economic impact. The effects of the home environment and exposure to volatile organic compounds (VOCs) and fine particulate matter (PM2.5) on adults with asthma remain unknown. In addition, methods currently used to assess the home environment do not capture real-time data on potentially modifiable environmental exposures or their effect on asthma symptoms.

Objective: The aims of this study are to (1) determine the feasibility and usability of ecological momentary assessment (EMA) to assess self-report residential environmental exposures and asthma symptoms, home …

Manuscripts, Articles, Book Chapters and Other Papers

Manipulation of the microbiome is a rational treatment strategy for inflammatory bowel disease (IBD). Compared to the colon and terminal ileum (TI), understanding of the microbial composition in the duodenum is sparse. This gap in knowledge is especially significant for children with Crohn's disease (CD) because the prevalence of duodenal CD is higher in children than in adults. Our aim was to characterize the bacterial composition of the mucosally-adherent duodenal microbiome in children with and without CD as a first step toward development of targeted IBD treatment strategies at this disease location. Fresh-frozen mucosal biopsies were obtained from the duodenum …

Manuscripts, Articles, Book Chapters and Other Papers

Formula feeding is an important risk factor for the development of necrotizing enterocolitis in preterm infants. The potential harmful effects of different preterm formulas on the developing intestinal tract remain incompletely understood. Here we demonstrate that feeding newborn mouse pups with various preterm formulas resulted in differing effects on intestinal inflammation, apoptosis, and activation of the pro-inflammatory transcription factor NFκB. 16S rRNA sequencing revealed that each preterm formula resulted in significant gut microbial alterations that were different from dam-fed controls. Formula feeding with EleCare and Similac Special Care caused greater intestinal injury compared to NeoSure. Pre-treatment with Lactobacillus rhamnosus GG …

The Neglected Price Of Pediatric Acute Kidney Injury: Non-Renal Implications., Chetna K. Pande, Mallory B. Smith, Danielle E. Soranno, Katja M. Gist, Dana Y. Fuhrman, Kristin Dolan, Andrea L. Conroy, Ayse Akcan-Arikan

Manuscripts, Articles, Book Chapters and Other Papers

Preclinical models and emerging translational data suggest that acute kidney injury (AKI) has far reaching effects on all other major organ systems in the body. Common in critically ill children and adults, AKI is independently associated with worse short and long term morbidity, as well as mortality, in these vulnerable populations. Evidence exists in adult populations regarding the impact AKI has on life course. Recently, non-renal organ effects of AKI have been highlighted in pediatric AKI survivors. Given the unique pediatric considerations related to somatic growth and neurodevelopmental consequences, pediatric AKI has the potential to fundamentally alter life course outcomes. …

Congenital Co-Infections Among Hiv-Exposed Infants Born To Mothers On Antiretroviral Treatment In The United States., Christiana Smith, Lori Silveira, Megan Crotteau, Krystle Garth, Jennifer Canniff, Kirk B. Fetters, Sarah Lazarus, Shannon Capraro, Adriana Weinberg, Chip Perinatal Team

Manuscripts, Articles, Book Chapters and Other Papers

Background: Many women living with HIV (WLHIV) are co-infected with cytomegalovirus (CMV), Toxoplasma gondii (T gondii), and/or hepatitis C virus (HCV). The rates of congenital or perinatal transmission of these co-infections are not well defined in the current era, when most WLHIV receive antiretroviral therapy (ART) during pregnancy.

Methods: Retrospective review of infants of WLHIV born between 2009-2019. Mothers were screened for antibodies to CMV, T. gondii, and HCV; chronic HCV infection was confirmed using plasma RNA PCR. Infants whose mothers had positive/unknown serostatus were screened for CMV using urine or saliva DNA PCR or culture at ≤3 …

Neutralization capacity of antibodies against Omicron after a prior SARS-CoV-2 infection in children and adolescents is not well studied. Therefore, we evaluated virus-neutralizing capacity against SARS-CoV-2 Alpha, Beta, Gamma, Delta and Omicron variants by age-stratified analyses (5 years of age. As expected, convalescent pediatric COVID-19 and MIS-C cohorts demonstrate higher neutralization titers than hospitalized acute COVID-19 patients. Overall, children and adolescents show some loss of cross-neutralization against all variants, with the most pronounced loss against Omicron. In contrast to SARS-CoV-2 infection, children vaccinated twice demonstrated higher titers against Alpha, Beta, Gamma, Delta and Omicron. These findings can influence transmission, re-infection …

Differentially Methylated Cpgs In Response To Growth Hormone Administration In Children With Idiopathic Short Stature., Xiaojian Shao, Catherine Le Stunff, Warren A. Cheung, Tony Kwan, Mark Lathrop, Tomi Pastinen, Pierre Bougnères

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Recombinant human growth hormone (rhGH) has shown a great growth-promoting potential in children with idiopathic short stature (ISS). However, the response to rhGH differs across individuals, largely due to genetic and epigenetic heterogeneity. Since epigenetic marks on the methylome can be dynamically influenced by GH, we performed a comprehensive pharmacoepigenomics analysis of DNA methylation changes associated with long-term rhGH administration in children with ISS.

RESULTS: We measured DNA methylation profiles before and after GH treatment (with a duration of ~ 18 months in average) on 47 healthy children using customized methylC-seq capture sequencing. Their changes were compared and associated …

Wilms Tumor Presenting With Spontaneous Necrosis And Clostridium Perfringens Co-Infection, Ronald Palmen, Abbey Elsbernd, Kristin Palmen

Research Days

Background: Wilm’s Tumor (WT) is the most common renal malignancy of childhood. The initial presentation of WT may mimic infection or other malignancies with nonspecific symptoms including fever, abdominal/flank pain, or hematuria. This poses a diagnostic challenge for providers, particularly when both infection and malignancy are observed. We describe a case of WT with spontaneous necrosis initially obscured by overlying Clostridium perfringens infection, making diagnosis of the cancer difficult.

Case Description: A previously healthy 5-year-old girl presented to the emergency department with a two-day history of left flank pain and fevers. In the emergency department, she was tachycardic (130 bpm), …

Inpatient Outcomes For Children Receiving Empiric Methicillin-Resistant Staphylococcus Aureus Coverage For Complicated Pneumonia, Sophia Hackman

Research Days

Watch recording of live event

Background: Pediatric community acquired pneumonia is responsible for an estimated 124,000 hospitalizations annually in the United States, with up to 40% of hospitalized children subsequently developing a complicated pneumonia (i.e., effusion/empyema). Children with complicated pneumonia commonly require increased numbers of procedures, have exposure to broad-spectrum antibiotics, and have prolonged hospitalizations. While the prevalence of pneumonia has overall declined with childhood vaccination, the number of children with complicated pneumonia has remained stable. Current guidelines do not adequately address antibiotic management of pediatric complicated pneumonia specifically when to utilize methicillin-resistant Staphylococcus aureus (MRSA) coverage, likely contributing to …

Improving Antibiotic Durations For Skin And Soft Tissue Infections In Pediatric Urgent Care Clinics, Megan Hamner

Research Days

Watch recording of live event

Problem Statement/Question: Although national guidelines recommend 5-7 days of oral antibiotics for most skin and soft tissue infections (SSTIs), in 2019, CMH urgent care clinics (UCCs) prescribed > 7-day courses for 42% of patients diagnosed with SSTIs. Prolonged antibiotic courses result in increased patient burden, cost and adverse events which could be prevented by prescribing shorter courses.

Background/Project Intent (Aim Statement): To increase the percentage of patients receiving 5- 7 days of oral antibiotics for SSTIs from 58% to 75% by December 31st, 2021, in CMH UCCs.

Methods (include PDSA cycles): We formed a multidisciplinary team …
