Children in low-resource settings carry enteric pathogens asymptomatically and are frequently treated with antibiotics, resulting in opportunities for pathogens to be exposed to antibiotics when not the target of treatment (i.e., bystander exposure). We quantified the frequency of bystander antibiotic exposures for enteric pathogens and estimated associations with resistance among children in eight low-resource settings. We analyzed 15,697 antibiotic courses from 1,715 children aged 0 to 2 y from the MAL-ED birth cohort. We calculated the incidence of bystander exposures and attributed exposures to respiratory and diarrheal illnesses. We associated bystander exposure with phenotypic susceptibility of E. coli isolates in …

Microrna Expression Levels Change In Neonatal Patients During And After Exposure To Cardiopulmonary Bypass., Lance Hsieh, Lan N. Tu, Alison Paquette, Quanhu Sheng, Shilin Zhao, Douglas C. Bittel, James O'Brien, Kasey Vickers, Peter Pastuszko, Vishal Nigam

Manuscripts, Articles, Book Chapters and Other Papers

Background The systemic inflammation that occurs after exposure to cardiopulmonary bypass (CPB), which is especially severe in neonatal patients, is associated with poorer outcomes and is not well understood. In order to gain deeper insight into how exposure to bypass activates inflammatory responses in circulating leukocytes, we studied changes in microRNA (miRNA) expression during and after exposure to bypass. miRNAs are small noncoding RNAs that have important roles in modulating protein levels and function of cells. Methods and Results We performed miRNA-sequencing on leukocytes isolated from neonatal patients with CPB (n=5) at 7 time points during the process of CPB, …

An Enzymatically Cleavable Tripeptide Linker For Maximizing The Therapeutic Index Of Antibody-Drug Conjugates, Candice M Haase, Ningyan Zhang, Zhiqiang An, Kyoji Tsuchikama

Faculty, Staff and Student Publications

Valine-citrulline is a protease-cleavable linker commonly used in many drug delivery systems, including antibody-drug conjugates (ADC) for cancer therapy. However, its suboptimal in vivo stability can cause various adverse effects such as neutropenia and hepatotoxicity, leading to dose delays or treatment discontinuation. Here, we report that glutamic acid-glycine-citrulline (EGCit) linkers have the potential to solve this clinical issue without compromising the ability of traceless drug release and ADC therapeutic efficacy. We demonstrate that our EGCit ADC resists neutrophil protease-mediated degradation and spares differentiating human neutrophils. Notably, our anti-HER2 ADC shows almost no sign of blood and liver toxicity in healthy …

Breast Cancer In A Teenage Girl With Brca Mutation: A Case Report From A Low Middle-Income Country, Lubna Mushtaque Vohra, Danish Ali, Syeda Amrah Hashmi, Meher Angez

Section of General Surgery

Introduction: A staggering majority of pediatric breast masses are benign (mostly fibroadenoma) and so a biopsy is not readily performed as it can potentially lead to a future breast disfigurement. However, this should not be standard practice as this can lead to a delayed diagnosis, and hence, the treatment of pediatric breast cancer (BC); this was also seen in our patient's scenario.
Case history: Here, we report the case of the youngest known breast cancer patient in Pakistan, a 15-year-old girl. The right-sided breast lump which was diagnosed clinically as a fibroadenoma later turned out to be stage IIb pT3N0M0 …

Knowledge And Practice Of Pediatricians In Kenya Regarding Helicobacter Pylori Infection In Children., Aura Mwende Nzinga

Master of Medicine in Paediatrics and Child Health

Background: Helicobacter pylori is one of the most common chronic bacterial infections. It affects more than half of the world’s population and is frequently associated with peptic ulcer disease, gastric carcinoma and other extra gastrointestinal manifestations. Globally, one third of the children are infected with the highest burdens observed in low and middle income countries. In Kenya the prevalence stands at 87% among school going children and 50% in children under three years. Justification: Studies in high income countries suggest poor knowledge and practice amongst physicians with limited data from Africa. There exists conflicting information regarding the pathogenic role and …

Education For Children And Adolescents Living With Disabilities In Sub–Saharan Africa—The Gaps And Opportunities, Pauline Samia, Katherine Oyieke, Barnabas Kigen, Susan Wamithi

Paediatrics and Child Health, East Africa

The World Health Organization (WHO) defines disability as an umbrella term that covers impairments, activity limitations, and restrictions in participation (1). Disability is not considered a health problem, but rather an interaction between a person’s body functions and features of the environments in which they live (1). WHO report a higher prevalence of severe and moderate disabilities in Africa compared to other regions (1). The United Nations Children’s Fund (2021) provides a global estimate of 230 million children, ages 0–17 years, living with a disability with 28.9 million children found in Eastern and Southern Africa (2). More than half of …

Impact Of Remote Monitoring During The Interstage Period On Outcomes In Single Ventricle Patients Across Socioeconomic Groups, Bianca Cherestal, Lori Erickson, Janelle R. Noel-Macdonnell, Girish S. Shirali, Hayley S. Hancock, Doaa Aly, Natalie Jayaram

Posters

Background: Despite improvements in outcomes over time, morbidity and mortality for infants with single ventricle (SV) heart disease remains high. Among other risk factors for mortality, infants of low socioeconomic status (SES) are known to be particularly vulnerable following stage 1 palliation. We sought to determine whether use of a novel remote monitoring program, CHAMP (Cardiac High Acuity Monitoring Program), mitigates differences in outcomes by SES for infants with SV during the interstage period. Methods: Using the CHAMP database, we identified 607infants across 11 institutions enrolled in the program between 2014–2021. All enrolled patients’ families were provided with a Windows-based …

Safety, Timing, And Outcomes Of Early Postoperative Cardiac Catheterization Following Congenital Heart Surgery, Karoline Krzywda, Jeremy Affolter, Darcie Al-Hassan, William Gibson, Ryan Romans, Kelly S. Tieves

Posters

Intro: Historically, early postoperative (<6weeks) cardiac catheterization (EPOCC) was considered high risk and often delayed. Recently, the safety of early postoperative cardiac catheterization has been demonstrated. The timing of catheterization in the struggling postoperative patient remains variable and optimal timing remains uncertain. There is limited data on the impact of EPOCC on outcomes such as length of stay, duration of mechanical ventilatory or extracorporeal support, and surgical or catheter- based interventions. The aim of this study was to describe our experience with EPOCC and its impact on management, length of stay, and duration of mechanical ventilatory support. Methods: This is a descriptive retrospective cohort study of patients who underwent cardiac surgery between 01/01/2010 and 12/31/2019 and cardiac catheterization within 30 days after surgery. Patients with catheterization for LA decompression on ECMO, endomyocardial biopsy, or BAS post hybrid procedure were excluded. We collected information surrounding timing, indication, and complications of catheterization, duration of mechanical ventilation/ECMO, and ICU/hospital LOS and compared these differences in patients who underwent EPOCC < 72hours (earlier) versus >72hours (later). Data was analyzed using IBM SPSS, version 28. Chi-square and Student’s t-test, or appropriate nonparametric tests were used to compare categorical and continuous variables, respectively. Results: There were 2542 surgeries performed during the study period with 167 patients undergoing cardiac catheterization within the defined 30 days. Twenty-six patients met exclusion criteria, leaving 141 patients for analyses. Median time from surgery to EPOCC was 10 days (1-30), with 26 patients(18.4%) having an earlier EPOCC. Interventions were performed in 70 patients (49.6%), not statistically different in those with earlier vs later EPOCC [n=9 (12.9%) vs …

A Quality Improvement Initiative To Decrease Time To Analgesia In Patients With Sickle Cell And Vaso-Occlusive Crisis: A Population With Disparities In Treatment, Sean Thompson

Faculty, Staff and Student Publications

INTRODUCTION: Vaso-occlusive crises (VOCs) are the leading cause of emergency department (ED) visits and hospitalizations in patients with sickle cell disease (SCD). Timely administration of analgesia, within 60 minutes of patient registration, is the standard of care for SCD patients with VOCs. Patients with VOCs have longer times to initial analgesia compared to similar painful conditions. The primary aim of the project is to have 75% of patients with VOCs receive initial analgesia within 60 minutes of being registered, the current recommended time frame from the National Heart, Lung, and Blood Institute (NHLBI).

METHODS: A multi-disciplinary team used quality improvement …

Machine Learning-Based Prediction Of Masked Hypertension Among Children With Chronic Kidney Disease, Susan L Furth

Faculty, Staff and Student Publications

BACKGROUND: Ambulatory blood pressure monitoring (ABPM) is routinely performed in children with chronic kidney disease to identify masked hypertension, a risk factor for accelerated chronic kidney disease progression. However, ABPM is burdensome, and developing an accurate prediction of masked hypertension may allow using ABPM selectively rather than routinely.

METHODS: To create a prediction model for masked hypertension using clinic blood pressure (BP) and other clinical characteristics, we analyzed 809 ABPM studies with nonhypertensive clinic BP among the participants of the Chronic Kidney Disease in Children study.

RESULTS: Masked hypertension was identified in 170 (21.0%) observations. We created prediction models for …

Are Women With Disabilities Less Likely To Utilize Essential Maternal And Reproductive Health Services?-A Secondary Analysis Of Pakistan Demographic Health Survey, Shafaq Mahmood, Waqas Hameed, Sameen Siddiqi

Community Health Sciences

Background: People with disabilities deal with widespread exclusion from healthcare services, including sexual and reproductive health (SRH) rights. Studies analyzing the relationship between disability and key SRH utilization outcomes have often reported mixed findings. In Pakistan, very little to no literature is available on this topic, therefore we aim to determine inequalities in the utilization of essential maternal and reproductive health services between women with and without disabilities in Pakistan.
Methods: This was a secondary analysis of Pakistan Demographic Health Survey 2017-18 performed on a weighted sample of 6,711 women aged 15-49 years with a live birth in the 5 …

Background: Hip-worn accelerometer cut-points have poor validity for assessing children's sedentary time, which may partly explain the equivocal health associations shown in prior research. Improved processing/classification methods for these monitors would enrich the evidence base and inform the development of more effective public health guidelines. The present study aimed to develop and evaluate a novel computational method (CHAP-child) for classifying sedentary time from hip-worn accelerometer data.

Methods: Participants were 278, 8-11-year-olds recruited from nine primary schools in Melbourne, Australia with differing socioeconomic status. Participants concurrently wore a thigh-worn activPAL (ground truth) and hip-worn ActiGraph (test measure) during up to 4 …

Background: A better understanding of the extent to which psychosocial and environmental correlates of physical activity are specific to locations would inform intervention optimization.

Purpose: To investigate cross-sectional associations of location-general and location-specific variables with physical activity and sedentary time in three common locations adolescents spend time.

Methods: Adolescents (N = 472,Mage = 14.1,SD = 1.5) wore an accelerometer and global positioning systems (GPS) tracker and self-reported on psychosocial (e.g., self-efficacy) and environmental (e.g., equipment) factors relevant to physical activity and sedentary time. We categorized each survey item based on whether it was specific to a location to generate psychosocial …
