Department of Paediatrics and Child Health

Background: Respiratory syncytial virus (RSV) is an important cause of infant morbidity and mortality and a potential target for maternal immunization strategies. However, data on the role of RSV in young infant deaths in developing countries are limited.
Methods: We conducted a community-based mortality surveillance from August 2018-March 2020 for infants ≤6 months in Karachi, Pakistan. We tested (reverse transcription-polymerase chain reaction) nasopharyngeal swabs from deceased infants for presence of RSV. We performed verbal autopsies and calculated odds of RSV-associated mortality with 95% CIs and used multivariable logistic regression to evaluate associations.
Results: We collected 490 nasopharyngeal specimens from 1280 …

Challenges Of Assessing Community Mortality Due To Respiratory Viruses In Children Aged Less Than 5 Years, Mauricio T. Caballero, Ashish Satav, Christopher J. Gill, Saad B. Omer, Rachel C. Pieciak, Abdul Momin Kazi, Eric Af Simões, Fernando P. Polack

Department of Paediatrics and Child Health

Background: Estimating the real impact of respiratory syncytial virus (RSV) disease is key for the development of vaccines and treatments. Ascertaining the burden of community mortality due to RSV is challenging due to the lack of primary data. Therefore, conducting observational studies to determine the factors associated with community mortality due to the virus in developing countries is important.
Objective: Our aim in this study was to describe the obstacles, gaps, and challenges that investigators face in low-income, vulnerable regions in 4 developing countries on 3 continents.
Results: The main obstacles and challenges of ascertaining community mortality due to RSV …

The Good Food For Learning Universal Curriculum-Integrated Healthy School Lunch Intervention: Protocol For A Two-Year Matched Control Pre-Post And Case Study, Rachel Engler-Stringer, Jennifer Black, Nazeem Muhajarine, Wanda Martin, Jason Gilliland, Janet Mcvittie, Sara Kirk, Hannah Wittman, Amin Mousavi, Sinikka Elliott, Brent Hills, Gordon Androsoff, Debbie Field, Brit Macdonald, Chelsea Belt, Hassan Vatanparast

Paediatrics Publications

Background: Good nutrition affects children's health, well-being, and learning, and schools offer an important setting to promote healthy behaviors that can last a lifetime. Once children reach school age, they spend more of their waking hours in school than in any other environment. Children's eating habits may be easier to influence than those of adults. In Canada, households with children are more likely to experience food insecurity, and school food programs that are universally available to all children can support the development of healthy eating patterns across groups of varying socioeconomic status. There is a significant gap in the rigorous …

Centre of Excellence in Women and Child Health

Background: Incomplete vital registration systems mean that causes of death during pregnancy and childbirth are poorly understood in low-income and middle-income countries. To inform global efforts to reduce maternal mortality, we compared physician review and computerised analysis of verbal autopsies (interpreting verbal autopsies [InterVA] software), to understand their agreement on maternal cause of death and circumstances of mortality categories (COMCATs) in the Community-Level Interventions for Pre-eclampsia (CLIP) cluster randomised trials.
Methods: The CLIP trials took place in India, Pakistan, and Mozambique, enrolling pregnant women aged 12-49 years between Nov 1, 2014, and Feb 28, 2017. 69 330 pregnant women were …

Relationship Between Sexual Activity, Contraceptive Utilization And Biopsychosocial Characteristics Among Homeless Shelter Adolescents., Brittney A Gaudet, Nina Liu, Allison N Kayne, Taylor L Jarvill, Cecilia Zemanek, Jeffrey M Downen, Hoonani M Cuadrado, Amy B Smith, Marna R Greenberg, Jessica L Jacoby, Joanne N Quinones

Department of Emergency Medicine

Objective: To determine whether biopsychosocial factors are associated with sexual activity and contraceptive utilization among homeless shelter adolescents. Methods: A retrospective study of 440 adolescents at a shelter in Pennsylvania between February 2015 and September 2019 was conducted. The cohort was evaluated to determine what relationship age, gender identity, substance use, and trauma history have with sexual activity and contraceptive utilization. Results: Sexual activity was significantly related to age (mean 15.8+1.4 years in sexually active vs. 14.7+1.6 years in abstinent youth, p<0.001); remote history of self-harm behavior (relative risk ratio (RR) 1.23 [95% CI 1.03-1.46]; p=0.02), history of aggressive behavior (RR 1.21 [95% CI 1.01-1.46]; p=0.04), history of trauma (RR 1.24 [95% CI 1.04-1.48]; p=0.03), and substance use (RR 2.27 [95%CI 1.86-2.77]; p<0.001). There were 55.7% sexually active females vs. 42.50% males reporting contraception use (p=0.01). After adjustment, older age and substance use remained significantly associated with sexual activity (adjusted odds ratio (AOR) 1.58 [95% CI 1.36-1.83]; p<0.001 and AOR 5.18 [95% CI 3.28-8.18]; p<0.001, respectively). Conclusions: Females self-reported sexual activity using contraception more than males. After adjustment, older age and substance use were associated with sexual activity. By better understanding the impact these factors can have on contraceptive utilization, informed policy and practice interventions can be developed and implemented to help increase safe sex practices in spaces where homeless adolescents access healthcare.

Introduction: Prophylactic preoperative antibiotics (PPA) are questionable in cases with a low rate of surgical site infection (SSI). We report institutional PPA usage and SSI rates after elective laparoscopic cholecystectomy in a children’s hospital. Methods: Children <18 years old who underwent outpatient laparoscopic cholecystectomy between 7/2010 and 8/2020 were included. SSI was defined as clinical signs of infection, requiring antibiotics, within 30 days of surgery. Results: 502 patients met inclusion criteria; 50% were pre-operatively diagnosed with symptomatic cholelithiasis, 47% biliary dyskinesia, 2% hyperkinetic gallbladder, and 1% gallbladder polyp(s). The majority were female (78%) and Caucasian (80%). 60% (n=301) of patients received PPA while 40% (n=201) did not; 1.3% (n=4) of those who received PPA developed SSI compared to 5.5% (n=11) of those who did not (p=0.01). Though PPA use was associated with an 84% reduction in risk of SSI on multivariate analysis (p=0.01), all SSIs were superficial. One child required readmission for intravenous antibiotics while the remainder were treated with outpatient antibiotics. Gender, age, BMI, ethnicity, and preoperative diagnosis did not influence the likelihood of receiving PPA (Table 1). Conclusion: Given the relatively low morbidity of the superficial SSI, conservative use of PPA should be carefully considered in outpatient laparoscopic cholecystectomy to avoid contributing to antibiotic-related complications.

The liver is the primary organ responsible for clearing most drugs from the body and thus determines systemic drug concentrations over time. Drug clearance by the liver appears to be directly related to organ size. In children, organ size changes as children age and grow. Liver volume has been correlated with body surface area (BSA) in healthy children and adults and has been estimated by functions of BSA. However, these relationships were derived from "typical" populations and it is unknown whether they extend to estimations of liver volumes for population "outliers," such as children with overweight or obesity, who today …

Improving Skin And Soft Tissue Antibiotic Duration Concordance With National Guidelines In Pediatric Urgent Care Clinics, Megan Hamner, Amanda Nedved, Holly Austin, Donna Wyly, Alaina N. Burns, Diana King, Brian Lee, Rana El Feghaly

Posters

Introduction: Skin and soft tissue infections (SSTIs) are the second most common diagnosis leading to pediatric antibiotic prescriptions in the outpatient setting after respiratory diagnoses. Children with SSTIs often receive >7 days of antibiotics, although current guidelines recommend 5-7 days for most diagnoses. At CMH urgent care clinics (UCCs), only 58% patients received the recommended 5-7 days of antibiotics. We aimed to increase the percentage of patients receiving 5-7 days of oral antibiotics for SSTIs from 58% to 75% by December 31st, 2021. Methods: We formed a multidisciplinary team in April 2020. A provider survey assessed factors influencing prescribing habits. …

Background: Selenium (Se), an essential trace mineral, has been implicated in preterm birth (PTB). We aimed to determine the association of maternal Se concentrations during pregnancy with PTB risk and gestational duration in a large number of samples collected from diverse populations.
Methods: Gestational duration data and maternal plasma or serum samples of 9946 singleton live births were obtained from 17 geographically diverse study cohorts. Maternal Se concentrations were determined by inductively coupled plasma mass spectrometry analysis. The associations between maternal Se with PTB and gestational duration were analysed using logistic and linear regressions. The results were then combined using …

Classical Findings Of Infantile Hepatic Hemangiomas, Senayit Demie, Michael Bossak

HCA Healthcare Journal of Medicine

Introduction

Hemangiomas are benign vascular tumors that are common during infancy. They are most commonly noted as superficial bright red lesions on the skin but can also be found deeper as subcutaneous lesions. Patients with multifocal cutaneous hemangiomas are at risk of visceral involvement with the liver being most commonly affected. Most hemangiomas can be monitored clinically as they are self-limiting. Despite this, hepatic hemangiomas can have serious complications including large arteriovenous shunts leading to cardiac compromise as well as severe hepatomegaly which can cause abdominal compartment syndrome, impaired ventilation and renal vein compression.

The Role Of The Pharmacist In The Treatment Of Infantile Botulism, Rachel E. Huntsman, Abigail Schauble

HCA Healthcare Journal of Medicine

Infantile botulism is a potentially devastating disease caused by ingestion of Clostridium botulinum spores through food products or dust particles. The toxin produced by the spores can lead to descending paralysis requiring hospitalization for supportive care which sometimes includes mechanical ventilation. Human Botulism Immune Globulin-Intravenous (BIG-IV or BabyBIG) from the Infant Botulism Treatment and Prevention Program (IBTPP) has been shown to greatly improve outcomes. A previously healthy 5-month-old infant was admitted to her regional hospital for poor feeding and lethargy. When the weakness progressed and she had trouble with protecting her airway, she was intubated and transferred to our institution. …

Nucleated Red Blood Cells As A Biomarker For Mortality In Neonates Following Cardiac Surgery, Kurt D. Piggott, Syeda Maqsood, Cynthia L. Warner, Timothy Pettitt, Shengping Yang, Jason Turner, Amira Soliman, Casey Norlin, Latasha Lewis, Ajay Bhatia

School of Medicine Faculty Publications

Introduction: Nucleated red blood cells (NRBCs) are immature red cells that under normal conditions are not present in the peripheral circulation. Several studies have suggested an association between elevated NRBC and poor outcome in critically ill adults and neonates. We sought to determine if elevations in NRBC value following cardiac surgery and following clinical events during the hospital stay can be used as a biomarker to monitor for mortality risk in neonates post-cardiac surgery. Materials and methods: We constructed a retrospective study of 264 neonates who underwent cardiac surgery at Children's Hospital, New Orleans between 2011 and 2020. Variables included …
