College of Population Health Faculty Papers

BACKGROUND: Pakistan's persistently high maternal (178 per 100 000 livebirths) and neonatal (41 per 1000 livebirths) mortality ratios are compounded by lack of reliable data on the root causes and preventable risk factors, which hinders their effective use in improving care and progress toward safe, high-quality services. We sought to identify system delays impacting maternal and perinatal deaths using a facility-based death audit review system integrated with community engagement for implementing actionable solutions.

METHODS: We used a mixed methods, concurrent parallel study design at three secondary level healthcare facilities in District Matiari, Sindh, Pakistan. We reviewed 319 cases that included …

Engineering Function In Lung Biology: Integrating Imaging, Regenerative Constructs, And Functional Biodesign, Rene A Girard, Jamie Tran, Yuqing Cai, Mary C Farach-Carson, Hadi T Nia, Allison M Greaney, Laura E Niklason, Killian Hurley, Elvin Blanco, Sinem Koc-Günel, Harry Karmouty-Quintana

Faculty, Staff and Student Publications

The lung is a uniquely demanding target for regeneration because function depends on the coordinated integration of cellular diversity, three-dimensional architecture, cyclic mechanical forces, vascular perfusion, immune surveillance, and extracellular matrix remodeling. While single-cell and spatial profiling, lineage tracing, and iPSC-derived models have transformed our understanding of lung cell states and developmental potential, these descriptive approaches have also highlighted a central bottleneck: the field still lacks broadly adopted platforms to test whether engineered tissues and regenerative interventions restore function under physiologic load. In this review, we focus on emerging technologies that enable functional biodesign in lung biology by coupling engineered …

A Risk-Based Model For Unplanned Cesarean Delivery Following Induction Of Labor In Term Hypertensive Nulliparas., Avihu Krieger, Michal Axelrod, Baha Sibai, Shalom Mazaki-Tovi, Michal Fishel Bartal

Faculty, Staff and Student Publications

Purpose: To develop a practical risk-stratification framework for unplanned cesarean delivery (CD) among term nulliparous individuals with hypertensive disorders of pregnancy (HDP) undergoing induction of labor (IOL).

Methods: This was a retrospective cohort study at a single tertiary care center (January 2010-March 2025) of nulliparous individuals with singleton gestations diagnosed with HDP undergoing IOL at ≥ 37 + 0 weeks. We excluded multiple gestations, major fetal anomalies, planned CD, or intrauterine fetal death. We included demographic and pregnancy characteristics available prior to induction and evaluated association with unplanned CD. Stepwise backward logistic regression was used to build a model for …

Modeling Early Human Heart Development Using An Ipsc-Based 3d Bioprinted Model Of Embryonic Heart Tube, Linqi Jin, Christian Park, Sunder Neelakantan, Shweta Karnik, Arnab Dey, Sarah Fineman, Roshni Nandwani, Carmen J Gil, Boeun Hwang, Melissa A Cadena, Vani Sridhar, Jing Wang, Yuxiao Wu, Connor J Evans, Lan Li, Sarah Rezapourdamanab, Mehdi Salar Amoli, Martin L Tomov, Ryan K Roeder, Reza Avazmohammadi, Lakshmi Prasad Dasi, Hanjoong Jo, Eric Weeks, Holly D Bauser-Heaton, Sean M Wu, Vahid Serpooshan

Faculty, Staff and Student Publications

Human heart development depends on tightly coordinated genetic programs and biomechanical cues, yet the underlying cell-microenvironment interactions remain poorly understood because the developing heart is difficult to study in utero and accurate experimental models are lacking. Recent advances in stem cell biology and three-dimensional (3D) bioprinting now allow the construction of human tissue analogues with defined structure and function. Here we show a perfusable 3D bioprinted model of the human embryonic heart tube composed of layered myocardium, cardiac jelly, and endocardium. Human induced pluripotent stem cell-derived cardiomyocytes and endothelial cells are cultured under controlled flow conditions, producing constructs with high …

Increased oxygen levels at birth regulate myocyte bioenergetic and structural maturation controlled by mitochondrial cyclophilin D (CypD). We evaluated mechanisms of neonatal hypoxic cardiac dysfunction by exposing neonatal mice to 12% oxygen and studied cardiac bioenergetics, myocyte maturation, and function. Hypoxia decreased the activity/assembly of electron transport chain complex I, uncoupled oxidative phosphorylation, increased proliferation, decreased differentiation, increased ventricular mass, and decreased cardiac function. CypD inhibition rescued most hypoxia-mediated effects and increased cardiac function. In conclusion, neonatal hypoxia alters cardiac bioenergetics, myocyte maturation, and cardiac function through CypD-dependent pathways, providing potential therapeutic targets for neonatal cardiac dysfunction.

Pediatric Thyroid Cancer Lung Metastases And Rai: Long-Term Results, Ryan C Mueller, Nikhil Rammohan, Anthony J Apicelli, Ana Maria Arbelaez, Farrokh Dehdashti, Barry A Siegel, Vikas Prasad, Perry W Grigsby, Stephanie Markovina

2020-Current year OA Pubs

OBJECTIVES: Children with differentiated thyroid cancer (DTC) often present with lung metastases but historically have good outcomes. Radioactive iodine (RAI) is commonly used to treat these children. Given the rarity of this condition, little evidence detailing long-term outcomes and risk of radiation pneumonitis exists.

METHODS: We conducted a retrospective analysis of patients < 20 years old who received RAI for DTC lung metastases between 1973 and 2018. Disease-free survival (DFS) was calculated from diagnosis to last follow-up. Overall survival and rates of acute and late radiation pneumonitis were determined by chart review and obituary searches.

RESULTS: Sixteen patients met eligibility criteria. Fourteen presented with thyroid, nodal, and lung disease; one presented with thyroid and nodal disease with nodal and lung recurrence; and one presented with thyroid-only disease with nodal and lung recurrence. All patients underwent thyroidectomy, 10 underwent neck dissection, and four underwent …

Sex-Aware Genome-Wide Assessment Of De Novo Variants In Autism Across Coding And Noncoding Regions, Tychele N Turner

2020-Current year OA Pubs

BACKGROUND: Autism spectrum disorder (ASD) shows a consistent sex bias, yet how sex shapes de novo variant (DNV) risk across coding and noncoding sequence remains unclear. I analyzed DNVs in > 41,000 parent–child sequenced trios from three ASD family-based cohorts and compared DNV characteristics and enrichment patterns in males and females. Notably, these trios included individuals with ASD as well as those without ASD. I developed a new sex-aware DNV caller (HAT-FLEX) and thoroughly evaluated each candidate DNV using an additional tool introduced in this study, SNOW, to generate a high-confidence callset. RESULTS: I identified enrichment of missense and loss-of-function (LOF) …

Speed Of Intravenous Fluid On Glycocalyx Integrity And Central Blood Volume In A Porcine Septic Shock Model, Yosef Levenbrown, Md Jobayer Hossain, Paul T. Fawcett, Marjorie Postell, Anne M. Hesek, Lynell S. Jones, James P. Keith, Thomas H. Shaffer

Department of Pediatrics Faculty Papers

BACKGROUND: It is unclear whether the rate of intravenous fluid (IVF) administration in sepsis influences glycocalyx breakdown. This study aimed to measure the effect of rapid versus slow fluid bolus in a septic pig model on the integrity of the glycocalyx by measuring the serum levels of heparan sulfate and syndecan-1, breakdown products of the glycocalyx. Because endothelial glycocalyx is composed of apical cell membrane-bound proteoglycans such as syndecan-1, covalently bound with long linear glycosaminoglycans such as heparan sulfate, shedding of these different glycocalyx components is closely related. Additionally, we measured central blood volume (blood volume in the heart and …

Identification Of Lipid Quantitative Trait Loci Linked With Cardiometabolic Disease In Asian Indians And Europeans: A Genome-Wide Association Study And Mendelian Randomization, Madhusmita Rout, Christopher E. Aston, Ravindranath Duggirala, Harald H. H. Goring, Oliver Fiehn, Dharambir K. Sanghera

School of Medicine Publications

Background: Genetic mechanisms that predispose people to type 2 diabetes (T2D) and cardiovascular disease (CVD) remain poorly understood, partly because of a lack of sufficient data on non-European ethnic groups. Extending these evaluations to diverse cohorts is essential for gaining insights into the molecular pathways involved in disease development among human populations. In this study, we aimed to evaluate the genetic connection between the human lipidome and cardiometabolic disorders. We conducted a metabolite genome-wide association study (mGWAS) in a Punjabi population from India, along with multi-layer replication studies using the UK Biobank and other independent European and non-European cohorts.

Family-Based Gwas Of Cognitive Endophenotypes Reveals Genetic Architecture Of Memory And Executive Function In Alzheimer’S Disease, Kesheng Wang, Xueying Yang, Gayenell Magwood, Chun Xu, R. Osvaldo Navia, Jean Neils-Strunjas, Xiaoming Li

Health & Biomedical Sciences Faculty Publications

Alzheimer’s disease (AD), the most common cause of dementia, is characterized by progressive memory and cognitive decline. Conventional genome-wide association studies (GWAS) comparing AD cases and controls may miss genetic influences that act along a continuum of cognitive function. Using data from 3007 participants in the National Institute on Aging Late-Onset Alzheimer’s Disease Family Study (NIA-LOAD GWAS), we conducted a family-based GWAS of eight quantitative cognitive phenotypes encompassing episodic memory (Logical Memory IA and IIA), working memory (Digit Span Forward, Backward, and Ordering), and semantic fluency (Animal, Fruit and Vegetable, and Vegetable Fluency). Family-based association testing in PLINK v1.9 identified …

Glp-1 Receptor Agonists In Diabetic Foot And Ankle Care: Skeletal Liability Or A Blessing In Disguise? A Scoping Review, Daniela Lizbeth Avilez, Amanda Killeen

School of Podiatric Medicine - Student Research

Introduction: Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are increasingly prescribed for glycemic control and weight reduction in patients with Type 2 Diabetes Mellitus (T2DM). Patients with T2DM exhibit elevated fracture risk despite preserved bone mineral density due to impaired bone quality and microarchitectural compromise. Whether GLP-1 RA therapy exacerbates or mitigates skeletal risk remains clinically relevant to podiatric care.

Hypothesis: We hypothesized that GLP-1 RA therapy is not associated with increased lower extremity fracture risk and may demonstrate protective trends influenced by age and duration of therapy.

Methods: A review of PubMed and Google Scholar (2010–2026) was conducted. Inclusion criteria …

Mitochondrial Dna Replication Is Regulated By Endoplasmic Reticulum-Mitochondrial Contact Sites, The Mitochondrial Calcium Uniporter, And Manganese, Amaia Lopez De Arbina, Angelica Zamudio-Ochoa, Mikel Muñoz-Oreja, Diego Perez-Rodriguez, Laura Mosqueira-Martín, Rebecca Lasalandra, Marina Villar-Fernandez, Uxoa Fernandez-Pelayo, Laura Rodriguez-Gomez, Seungtae Lee, Francisco Gil-Bea, Nerea Osinalde, Ainara Vallejo-Illaramendi, Dmitry Temiakov, Antonella Spinazzola, Ian Holt

Department of Biochemistry and Molecular Biology Faculty Papers

Mitochondrial DNA replication occurs at contact sites between the endoplasmic reticulum (ER) and mitochondria (ERMCS). Beyond the known role of the tubular ER protein RTN4, the factors regulating this process are poorly defined. Here, we show that repressing the ER protein ERLIN2 in human fibroblasts depletes ER-mitochondrial contact sites and inhibits mitochondrial DNA replication, as does silencing RTN4 or the ER-mitochondrial tether GRP75. GRP75 or RTN4 scarcity also decreases the level of the mitochondrial calcium uniporter (MCU), whose inhibition blocks mitochondrial DNA synthesis. Because ERMCS depletion did not diminish mitochondrial calcium, and MCU complex can transport manganese, we tested whether …

Theory And Simulations Of Delayed Stochastic And Deterministic Models Of Prion Diseases, Gangadhara Boregowda, Omar Sharif, Daniel Gutierrez Iii, Allegra Simmons, Laurent Pujo-Menjouet, Tamer Oraby, Michael R. Lindstrom

School of Mathematical & Statistical Sciences Faculty Publications

Neurodegenerative diseases (NDs), such as Alzheimer’s, Parkinson’s, and prion diseases, are characterized by the dynamical spread of toxic proteins through the brain. In prion diseases, cellular prion protein (PrPC), produced by neurons, misfolds into a toxic form, known as scrapie prion protein (PrPSc). PrPSc induces neuronal stress which ultimately leads to cell death. In this paper, we develop mathematical models for the progression of prion diseases, incorporating a cellular defense mechanism that introduces a delay term affecting protein translation and a volatility term accounting for unaccounted biological factors influencing the system. We also extend the model to capture the spatial …

UNLABELLED:

IMPORTANCE: Dual membrane-spanning anti-sigma factors (Dma) are a novel class of regulatory proteins found solely among Bacteroidota. Previous studies demonstrated the importance of Dma1 in vesiculation, but the overall role of the Dma family in Bacteroides physiology remains poorly understood. Here, we show that Dma2 modulates vesiculation and the expression of select polysaccharide utilization loci (PULs) that target host-associated glycans

Representation Of Active Girls, Women, And Female Athletes In Low Energy Availability Research: A Review, Ahnna E. Faust, Alexis V. Viehl, Melissa T. Lodge

Health Sciences Student Scholarship

More female athletes are participating in sports today than ever before, yet they remain underrepresented in sport and exercise science (SES) research. According to a 2021 review, 34% of SES research participants are females and just 6% of studies used female-only designs. Female athletes are also at an increased risk for low energy availability (LEA), or a mismatch between energy intake and exercise energy expenditure. However, the representation of women in research related to LEA remains unclear. PURPOSE: This study aimed to (a) evaluate the representation of girls, women, and female athletes in LEA research, and (b) explore methodological characteristics …

Using Lean Body Mass To Calculate Resting Metabolic Rate Across Gender Identities, Kara Dixon, Liza Goetcheus, Brett R. Ely

Health Sciences Student Scholarship

Accurate estimate of resting metabolic rate (RMR) is important for tailoring nutrition support in clinical settings. Metabolic rate is often calculated using the Harris-Benedict equations, which estimate metabolic rate using separate equations for men and women. PURPOSE: This study aims to develop a more inclusive, single predictive equation based on lean body mass instead of gender. METHODS: Six healthy individuals (Age: 22±5; BMI: 22.3±0.7) underwent assessment of resting metabolic rate (RMR) using indirect calorimetry, and full-body dual energy x-ray absorptiometry to measure lean body mass. RMR was divided by lean body mass to examine the relationship between muscle mass and …

Health Is Where The Huddle Is, Lyndsey Anthony, Anna E. Komistek, Philip C. Pritchett, Emma K. Swanson

SPARK Symposium Presentations

“Health is Where the Huddle Is”

Huddles are an evidence-based strategy to facilitate a culture of safety within nursing teams. A review of 158 huddle studies found that 44.3% reported improved clinical outcomes and 24.3% showed fewer medical errors when huddles were implemented (Pimentel et al., 2021). Currently, a local hospital’s 13-bed ICU lacks an effective system for nursing staff to huddle due to staffing constraints and the absence of monitor technicians, creating safety concerns when nurses leave monitors unattended. This project aims to implement an effective, nurse-led shift huddle that maintains continuous patient monitoring while also strengthening patient safety …
