Impact Of Medicaid Redetermination On Underserved Populations In Region 7 States: A Review, Brianna Parr

Capstone Experience

When the COVID-19 Public Health Emergency ended in May of 2023, Medicaid began the process of redetermination across the states and returned to its original eligibility rules. Because of this, the healthcare status of many Americans was affected, resulting in the loss of healthcare coverage for millions of people. Of those who have lost coverage, children make up almost half of the total. This paper assesses the negative effects of Medicaid redetermination on children and other underserved populations in communities across the four states in Region 7 (Nebraska, Iowa, Missouri, and Kansas) and identifies programs that these states can implement …

Sex, Race, And Primary Language On Opioid Prescribing In Pediatrics, Lubna Begum, Brian Begley, Catherine Cerniglia, Mones Aboeletta, Grace Gilbert, Justin Matthew, Stephen Meixner, Corinna Franklin, Rey Ramirez

Rowan-Virtua Research Day

Over-prescription of pain medication has led to an opioid epidemic in the United States. Many factors can contribute to the amount of pain medication prescribed to patients. The amount of pain medication prescribed to patients is affected by many factors and previous research has shown:

• Men are prescribed more than women
• Whites more than non-whites
• English-speaking more than non-English-speaking

The goal of the study was to look at whether this held true in a pediatric orthopedic population. We also looked at the trends in opiate prescribing over time.

How Physical Activity Implementation Strategies Changed During The Covid-19 Pandemic In Schools Enrolled In The Let’S Go! Program, Alexandra Peary

Honors College

Childhood obesity is a serious public health issue in the United States. Many children fail to meet the recommended daily physical activity of 60 minutes. Poor metabolic health at a young age puts children and adolescents at a significantly higher risk of developing chronic health issues in adulthood. With the potential to further exacerbate the obesity epidemic, the onset of the Covid-19 pandemic challenged students’ abilities to participate in structured physical activity, such as recess and physical education, due to school closures, strict social distancing guidelines, and hybrid or remote models of learning. This lack of structure and opportunities for …

Candee, James J. Sejvar, Sarah E. Hopkins

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Acute flaccid myelitis (AFM) is a severe illness similar to paralytic poliomyelitis. It is unclear how frequently AFM occurred in U.S. children after poliovirus elimination. In 2014, an AFM cluster was identified in Colorado, prompting passive US surveillance that yielded 120 AFM cases of unconfirmed etiology. Subsequently, increased reports were received in 2016 and 2018. To help inform investigations on causality of the recent AFM outbreaks, our objective was to determine how frequently AFM had occurred before 2014, and if 2014 cases had different characteristics.

METHODS: We conducted a retrospective study covering 2005-2014 at 5 pediatric centers in 3 …

Association Between Breastfeeding And Child Stunting In Mexico, Ana Paola Campos, Mireya Vilar-Compte, Summer Sherburne Hawkins

Department of Public Health Scholarship and Creative Works

Background: Globally, the prevalence of child stunting has been decreasing over the past decades. How-ever, in low-and middle-income countries such as Mexico, stunting is still the most prevalent form of undernutrition affecting a large number of children in the most vulnerable conditions. Breastfeeding has been identified as one of the key affordable and modifiable maternal health behaviors protecting against child stunting. Objective: To examine the association between breastfeeding (defined as never breastfed, any breast-feeding for <6 months, and any breastfeeding for ≥6 months) and other individual-, household-, and area-level factors with child stunting (defined as length/height-for-age-z-score for sex under –2 standard deviations of the World Health Organization child growth standards’ median) in Mexico. Methods: Secondary data analysis using the 2012 Mexican Health and Nutrition Survey, which allowed representativeness of rural and urban areas at national level and among 4 regions in Mexico. Our subset included data on 2,089 singleton Mexican children aged 6–35 months with information on previously identified risk and protective factors for stunting. We conducted fixed-and mixed-effects logistic regression models sequentially controlling for each level of factors. Findings: Overall, 12.3% of children were stunted and 71.1% were breastfed for ≥6 months. Any breast-feeding and being female were consistent protective factors against child stunting across all models. In contrast, child low birthweight, maternal short stature, higher number of children aged <5 years per household, and moderate to severe food insecurity were consistent risk factors for child stunting across all models. Conclusions: According to our findings, efforts to reduce child stunting in Mexico should include prenatal strategies aiming to prevent low birthweight offspring particularly among short-stature women, moderate to severe food insecure households, families with a higher number of children aged <5 years, and indigenous communities. Postnatal components should include multilevel strategies to support breastfeeding.

Harris, Russell Mcculloh, Rachel Aikman, Sara Cox, Lacy Malloch, Anita Walden, Jessica Snowden, Irene Mangan Chedjieu, Chester A. Wicker, Lauren Atkins, Lori A. Devlin

Manuscripts, Articles, Book Chapters and Other Papers

Studies often rely on medical record abstraction as a major source of data. However, data quality from medical record abstraction has long been questioned. Electronic Health Records (EHRs) potentially add variability to the abstraction process due to the complexity of navigating and locating study data within these systems. We report training for and initial quality assessment of medical record abstraction for a clinical study conducted by the IDeA States Pediatric Clinical Trials Network (ISPCTN) and the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) Neonatal Research Network (NRN) using medical record abstraction as the primary data …

Fichtenberg, Eric W. Fleegler, Arvin Garg, Laura M. Gottlieb, Matthew S S. Pantell, Megan T. Sandel, Adam Schickedanz, Robert S. Kahn

Manuscripts, Articles, Book Chapters and Other Papers

The social determinants of health (SDoH) are defined by the World Health Organization as the "conditions in which people are born, grow, live, work, and age." Within pediatrics, studies have highlighted links between these underlying social, economic, and environmental conditions, and a range of health outcomes related to both acute and chronic disease. Additionally, within the adult literature, multiple studies have shown significant links between social problems experienced during childhood and "adult diseases" such as diabetes mellitus and hypertension. A variety of potential mechanisms for such links have been explored including differential access to care, exposure to carcinogens and pathogens, …

Progress Toward Eliminating Mother To Child Transmission Of Hiv In Kenya: Review Of Treatment Guideline Uptake And Pediatric Transmission At Four Government Hospitals Between 2010 And 2012., Sarah Finocchario-Kessler, Kristine F. Clark, Samoel Khamadi, Brad J. Gautney, Vincent Okoth, Kathy Goggin, Hitsystem Study Team

Manuscripts, Articles, Book Chapters and Other Papers

We analyzed prevention of mother-to-child transmission (PMTCT) data from a retrospective cohort of n = 1365 HIV+ mothers who enrolled their HIV-exposed infants in early infant diagnosis services in four Kenyan government hospitals from 2010 to 2012. Less than 15 and 20 % of mother-infant pairs were provided with regimens that met WHO Option A and B/B+ guidelines, respectively. Annually, the gestational age at treatment initiation decreased, while uptake of Option B/B+ increased (all p's < 0.001). Pediatric HIV infection was halved (8.6-4.3 %), yet varied significantly by hospital. In multivariable analyses, HIV-exposed infants who received no PMTCT (AOR 4.6 [2.49, 8.62], p < 0.001), mixed foods (AOR 5.0 [2.77, 9.02], p < 0.001), and care at one of the four hospitals (AOR 3.0 [1.51, 5.92], p = 0.002) were more likely to be HIV-infected. While the administration and uptake of WHO PMTCT guidelines is improving, an expanded focus on retention and medication adherence will further reduce pediatric HIV transmission.
