Faculty, Staff and Students Publications

Diaprepes abbreviatus is an agricultural pest known to affect around 270 plant species across the Caribbean and the United States, posing significant challenges to pest management. Chemical control dominates management, but environmental and health concerns motivate microbiome-informed alternatives. However, limited information exists on the gut anatomy, physicochemical environment, and microbial composition of D. abbreviatus. In this study, we provide the first comprehensive characterization of the gut morphology, pH, and microbiota of adult D. abbreviatus in both females and males collected in Puerto Rico. Using dye-based gut tracing, we identified foregut, midgut, and hindgut or posterior gut compartments, and confirmed the …

Recognition And Management Of Persistent Chylomicronemia: A Joint Expert Clinical Consensus By The National Lipid Association And The American Society For Preventive Cardiology, Vijay Nambi, Diane Brisson, Iftikhar J Kullo, P Barton Duell, Erin D Michos, Michael D Shapiro, Gerald F Watts, Daniel Gaudet, Christie M Ballantyne

Faculty, Staff and Students Publications

Extreme hypertriglyceridemia, defined as triglyceride (TG) levels ≥1000 mg/dL, is almost always indicative of chylomicronemia. The current diagnostic approach categorizes individuals with chylomicronemia into familial chylomicronemia syndrome (FCS; prevalence 1-10 per million), caused by the biallelic combination of pathogenic variants that impair the lipolytic action of lipoprotein lipase (LPL), or multifactorial chylomicronemia syndrome (MCS, 1 in 500). A pragmatic framework should emphasize the severity of the phenotype and the risk of complications. Therefore, we endorse the term "persistent chylomicronemia (PC)" defined as TG ≥1000 mg/dL in more than half of the measurements to encompass patients with the highest risk for …

Rebuttal: Reduced Oxidative Capacity Of Skeletal Muscle Is Not An Inevitable Consequence Of Adult Ageing, Ian R. Lanza, Christopher W. Sundberg, Jane A. Kent

Physical Therapy Faculty Research and Publications

We thank Drs Marcinek and Ferrucci for their perspective on the inevitability of age-related declines in skeletal muscle oxidative capacity (Marcinek & Ferrucci, 2025). We agree that mitochondria have numerous roles in the cell beyond provision of chemical energy, many of which may be altered by ageing, but our focus in this debate is entirely on its role in energy production.

Reduced Oxidative Capacity Of Skeletal Muscle Is Not An Inevitable Consequence Of Adult Ageing, Ian R. Lanza, Christopher W. Sundberg, Jane A. Kent

Physical Therapy Faculty Research and Publications

Skeletal muscles support posture and locomotion, thermoregulation, cardiorespiratory function, metabolic health and other important aspects of life. Muscles generate chemical energy by synthesizing ATP through the creatine kinase reaction, glycolysis, and oxidative phosphorylation (oxphos), the latter of which produces the majority of ATP in the cell. Oxidative phosphorylation occurs in the mitochondrion, which is structured as a reticulum located near the ATPases responsible for powering the cross-bridge cycle, calcium pumps and membrane homeostasis (Glancy et al., 2015). Energy production in mitochondria is accomplished by coupling the oxidation of reducing equivalents (NADH, FADH₂) in the electron transport chain (ETC) …

Factors Associated With Health Decision-Making Autonomy On Own Healthcare Among Tanzanian Women: A 2022–2023 Demographic Health Survey Study, Tausi Seleman Haruna, Henry Ofori Duah, Rebecca Lee

College of Nursing Faculty Research and Publications

Background

Women’s health decision-making autonomy is fundamental for the health and well-being of women and their children. It empowers women to make health decisions and exercise their rights and choices surrounding their health. Like most parts of Africa, women’s autonomy in Tanzania remains contentious, with an estimated 19% prevalence of health decision-making autonomy in 2015. Given the impact of women’s health decision-making autonomy on women’s health outcomes and the fact that women’s health decision-making autonomy is an ongoing process affected by advancements in technology, economic growth, and social and cultural shifts, understanding the sociodemographic correlates of women’s autonomy is imperative. …

A New Environmental-Economic Footprint (En-Ec) Index For Sustainability Assessment Of Household Food Waste, Majid Bahramian, Courage Krah, Paul Hynds, Anushree Priyadarshini

Research Outputs: 2025-Present

As global food demand grows, the limited availability of natural resources exacerbates environmental and food security challenges. Household food waste is a major yet underexplored issue, contributing to inefficiencies, economic losses, and environmental harm. This study applies the Environmental-Economic Footprint (EN-EC) index to assess household food waste in Ireland. By integrating environmental and economic data, this index facilitates a comprehensive dual-perspective evaluation of food waste impacts. Data were collected from 1000 Irish households, analyzing waste patterns across 12 food categories. Environmental impacts were quantified using global warming potential (GWP) and water footprint (WF), while economic costs were based on waste …

Increasing Surgical Healthcare Utilization For Infants With Congenital Anomalies In Texas, Kathleen Hosek, Dailen Alonso, Timothy C Lee, Sundeep G Keswani, Alice King

Faculty, Staff and Students Publications

Introduction: Congenital anomalies (CAs) impact 3% of live births and account for disproportionately high healthcare costs. While many CAs require multidisciplinary care and surgical intervention, the overall financial impact of infants diagnosed with CA with surgical needs is unknown. We aim to evaluate and characterize the charges of care in infants with CA and surgical needs in Texas.

Methods: A database study using the Texas Inpatient Public Use Data File was performed to query infants (< 365 days) statewide from 1/2021 to 12/2021 for admissions with CA and involved organ system by ICD-10 codes. Encounters transferred to an outside hospital were excluded to avoid systematic double-counting. Descriptive statistics were performed.

Results: Of 376,215 total admissions, 81,666 had surgical needs with OR charges. While non-CA represent the majority of surgical admissions (63,895/81,666; 78.24%), CA-surgical admissions …

Living With Children And Economic Disadvantage Among Seniors, Lucie Schmidt, Lara Shore-Sheppard, Tara Watson

Economics: Faculty Publications

Using the 2000 Census and 2005–2019 American Community Surveys, we examine the propensity of older adults to live with children. We show that seniors from disadvantaged subgroups are more likely to live in multi- or skip-generational arrangements. Contextual factors associated with more multigenerational living include a less generous safety net and high housing costs. Skip-generational living is associated with high female incarceration rates. Conditional on demographic characteristics and these contextual factors, seniors in multigenerational living arrangements are less likely to be in poverty and those in skip-generational arrangements more likely. Overall, the findings are consistent with the possibility that multigenerational …
