Development Of A Clinical Prediction Model To Guide The Selective Use Of Spect/Ct In Papillary Thyroid Cancer, Liya Zhu, Junik Son, Lu Wang, Haifeng Hou, Byeong Cheol Ahn

Research outputs 2022 to 2026

Background: Radioiodine whole-body scan (WBS) is routinely performed after radioiodine therapy in papillary thyroid cancer (PTC), but its two-dimensional nature limits anatomical localization. The addition of single-photon emission computed tomography/computed tomography (SPECT/CT) improves diagnostic accuracy; however, routine use exposes patients to additional radiation, longer imaging time, and higher costs. This study aimed to establish a predictive model to identify which patients with PTC are more likely to benefit by adding SPECT/CT imaging after WBS, enabling selective rather than routine use. Methods: This retrospective study included 265 patients with pathologically confirmed PTC who underwent postoperative radioiodine therapy followed by WBS and …

Emerging Blood-Based Biomarkers For The Detection Of Parenchymal Brain Metastasis: Current Progress And Future Perspectives, Désirée Sexauer, Elin S. Gray, Helen Rizos, Pauline Zaenker, Aaron B. Beasley

Research outputs 2022 to 2026

Parenchymal brain metastases of solid malignancies remain a significant clinical challenge, as they are often detected at later symptomatic stages, which are typically associated with worse prognosis. Delayed detection limits treatment options and contributes to poor outcomes, while early detection is critical for improving patient outcomes and quality of life. In this comprehensive review, we investigated the potential use and challenges of blood-based biomarkers, including circulating tumor cells, cell-free DNA, noncoding RNAs, extracellular vesicles, proteins, and other immune-related biomarkers, for the early detection of parenchymal brain metastasis. The use of blood-based liquid biopsies offers a promising avenue for early detection …

Precision Exercise For Breast Cancer-Related Outcomes: Towards Personalised Training Based On Tumour, Treatment And Patient Characteristics, Cristina Crespo-Garcia, Anita Borsati, Dennis R. Taaffe, Carolyn J. Peddle-Mcintyre, John P. Campbell, Alice Avancini, Emily Jeffery, Daniel A. Galvao, Robert U. Newton

Research outputs 2022 to 2026

Exercise is a promising strategy associated with improved cancer-related outcomes through multiple biological mechanisms. However, current exercise guidelines largely adopt a one-size-fits-all approach and overlook inter-individual variability in response. Given the heterogeneity of breast cancer, precision exercise prescriptions may better target biological pathways linked to therapeutic efficacy and long-term prognosis. Observational studies consistently show that higher physical activity levels are associated with improved survival outcomes, including reduced all-cause and breast cancer-specific mortality. In contrast, evidence from interventional trials remains limited and inconsistent, with effects on tumour response and survival largely derived from secondary or exploratory analyses. These discrepancies likely reflect …

Maternal Child Maltreatment And Intimate Partner Violence: Effects On Perceptions Of Infant Temperment And The Mediating Role Of Emotion Regulation And Responsiveness, Jewelian N. Fairchild, G. Anne Bogat, Amy K. Nuttall, Alytia A. Levendosky, Joseph S. Lonstein, Maria Muzik

Psychology Faculty Publications

Purpose

Maternal adverse experiences, such as maltreatment in childhood and later intimate partner violence (IPV) during pregnancy, can disrupt the mother-child relationship and influence maternal perceptions of infant temperament. The present study explored how these adversities influence mothers’ views of their infants’ temperaments and examined the role of maternal emotion regulation and responsiveness to their infants as mediators of these relationships.

Methods

Using data from a longitudinal study of highly stressed, vulnerable women, 355 mothers retrospectively reported on their own childhood maltreatment, as well as their experiences of IPV and emotion regulation during pregnancy. Maternal responsiveness was coded using mother-infant …

Rude Awakening: An Examination Of The Incivility-Sleep Relationship Via Affect, Mallory A. Mccord, Gargi Sawhney, Nastassia M. Savage, Kristen M. Fisher

Psychology Faculty Publications

Despite the prevalence of incivility at work and the essential nature of sleep, study of this relationship is comparatively sparse in the organizational sciences literature. Further, although impaired sleep could logically impact how one interprets subsequent interpersonal interactions at work, the dominant approach is to study sleep as an outcome of perceived incivility. Therefore, we drew upon affective events theory, the affect-as-information hypothesis, and sleep physiology to argue that state affect, both positive and negative, can explain the relationship between perceived incivility and sleep quality in either direction. The hypotheses were tested using a between-subjects design with one-month time lags …

Hendrix, Jeremiah D. Momper, Robert Bies, Rachel K. Scott

CONRAD Publications

Background and Objective

Tenofovir (TFV)-based regimens are backbones of both HIV treatment and pre-exposure prophylaxis during pregnancy. Multiple studies have shown up to one-third decreases in dried blood spot tenofovir-diphosphate concentrations during pregnancy among participants taking tenofovir disoproxil fumarate (TDF). Currently, there are no mechanism-based models describing the pharmacokinetics of tenofovir diphosphate (the active anabolite) in peripheral blood mononuclear cells (PBMCs) of pregnant individuals receiving TDF or tenofovir alafenamide (TAF), and the mechanisms behind observed differences between dried blood spots and PBMCs remain unclear.

Methods

To address this gap, we developed a semi-mechanistic model to simultaneously describe the pharmacokinetics of …

CONRAD Publications

Innate immunity predictors of HIV-1 risk and pathogenesis vary with reproductive hormones, pregnancy, and lactation, yet the underlying mechanisms remain unclear. We hypothesized that pregnancy-associated physiological adaptations alter systemic microRNA (miRNA) expression, thereby regulating immunity, pathogenesis and susceptibility to infection. We analyzed 174 serum samples from 88 participants in a longitudinal cohort from Uganda and Zimbabwe across pre-pregnancy (PP), pregnancy (P), and postpartum breastfeeding (BF). Cell-free peripheral blood miRNAs (n = 2083) were profiled using HTG EdgeSeq. Pregnancy-specific miRNAs were identified by intersecting differentially expressed (DE) miRNAs from P vs. PP and P vs. BF comparisons. miRNA targets and pathways …

Evaluating Novel Targeted Combination Therapies For Gastrointestinal Cancers, Joseph A. Goode

Graduate Studies Theses and Dissertations 2026

Gastrointestinal (GI) cancers remain among the leading causes of cancer-related mortality worldwide, with therapeutic resistance continuing to limit the effectiveness of current treatments. Three complementary studies were conducted to identify therapeutic vulnerabilities and evaluate novel combination strategies in pancreatic ductal adenocarcinoma (PDAC) and colorectal cancer (CRC).  First, dual inhibition of fibroblast growth factor receptor 4 (FGFR4) and phosphoinositide 3-kinase (PI3K)/mammalian target of rapamycin (mTOR) signaling was investigated in PDAC models. A combination of targeted drug treatments reduced viability, clonogenic survival, migration, and suppressed signaling pathways involved in translational control. This supported a functional interaction between FGFR4 and PI3K-mTOR co-activation in …

The Diversity Of Flavivirus Antibody Dependent Enhancement (Ade) Profiles From A Pediatric Cohort In Mexico, Maiesha Samiha Mahmood

Graduate Studies Theses and Dissertations 2026

The Aedes mosquito-borne flaviviruses Zika (ZIKV) and dengue (DENV-1-4) cause an estimated 400 million annual infections globally and pose an increasing threat to public health. Typically, individuals infected with ZIKV or a DENV serotype generate neutralizing serotype-specific antibodies and non-neutralizing, cross-reactive antibodies that bind multiple flaviviruses. Upon secondary heterotypic infection, pre-existing antibodies can either protect or exacerbate disease through antibody dependent enhancement (ADE). ADE occurs when non- or sub-neutralizing concentrations of cross-reactive antibodies facilitate viral uptake into FcγR-bearing myeloid cells, enabling infection of otherwise non-permissive cells and driving severe disease. To date, ADE has not been characterized at a population …

Cardiovascular–Kidney–Metabolic Syndrome Through The Lens Of Gut‑Derived Uremic Toxins, Chudan Xu, Matthew Snelson, Francine Z. Marques

Research outputs 2022 to 2026

Cardiovascular–Kidney–Metabolic (CKM) syndrome represents a complex, interconnected cluster of cardiovascular disease, chronic kidney disease, and metabolic disorders such as obesity and type 2 diabetes. These conditions share overlapping metabolic, inflammatory, and vascular pathways, with the gut microbiome increasingly recognised as a key contributor and common underlying risk factor. Uremic toxins, traditionally considered waste products of host and microbial metabolism, are now recognised as active mediators of tissue damage across the CKM spectrum, particularly in the context of impaired renal function. Their production and accumulation are amplified by disrupted intestinal barrier integrity, chronic inflammation, and reduced renal clearance, collectively driving systemic …

Tuberculosis Presenting As Multiple Pulmonary Nodules Mimicking Malignancy, Abdel Martinez Borrego, Fatimah Bello, Brandon Cantazaro, Luisa Montoya, Frank Mediola

School of Medicine Publications

Multiple pulmonary nodules often raise concern for metastatic malignancy; however, the differential diagnosis is broad and includes infectious, inflammatory, granulomatous, vascular, and benign etiologies. Tuberculosis (TB), although uncommon, can present with multiple nodules that closely mimic metastatic disease on advanced imaging, requiring careful clinicoradiologic and microbiologic correlation. We describe a woman in her 50s who presented with dyspnea and new-onset heart failure, in whom imaging revealed mediastinal lymphadenopathy and bilateral pulmonary nodules concerning for malignancy. Evaluation was limited by concurrent COVID-19 infection, and CT-guided biopsy demonstrated necrotizing granulomas without evidence of malignancy or infection. She later re-presented with fever and …
