Physical Inactivity In Preclinical Alzheimer's Disease: Risk Factor, Early Symptom, Or Both, Jiawei Zhao, Xin Li, Mengxuan Wu, Zhanjun Zhang Jul 2026

Physical Inactivity In Preclinical Alzheimer's Disease: Risk Factor, Early Symptom, Or Both, Jiawei Zhao, Xin Li, Mengxuan Wu, Zhanjun Zhang

Communication Sciences & Disorders Faculty Publications

Physical inactivity is a key modifiable risk factor for Alzheimer's disease (AD). However, emerging evidence suggests a bidirectional relationship where inactivity also serves as an early manifestation of AD pathology. This perspective synthesizes recent findings from long-term epidemiological cohorts, brainstem neuropathology, and digital phenotyping to reconceptualize the role of inactivity in preclinical AD. Early tau accumulation in catecholaminergic nuclei (locus coeruleus and ventral tegmental area) disrupts circuits essential for reward valuation and effort calculation. We hypothesize that this neurobiological failure may manifest as prodromal apathy and declining physical activity years before cognitive impairment. Standard metrics like step counts fail to …

Laser Interstitial Thermal Therapy Enhances Bidirectional Blood-Brain Barrier Permeability In Glioblastoma, Ryan T Cleary, Yiwei Fu, David Giles, Jinyun Yuan, Diogo P Moniz Garcia, Danny Palmer, Rowland H Han, Timothy Woodiwiss, Alicia B Yang, Dimitrios Mathios, Hong Chen, Albert H Kim

2020-Current year OA Pubs

BACKGROUND: Laser interstitial thermal therapy (LITT) is a minimally invasive treatment for glioblastoma that increases blood-brain barrier (BBB) permeability. However, the mechanisms and spatiotemporal features of this effect remain unclear. It is also unknown whether LITT promotes release of circulating tumor DNA (ctDNA).

METHODS: Using our previously developed LITT mouse model, we employed single-cell RNA-sequencing (scRNA-seq) to investigate gene expression changes in endothelial cells following LITT in the naive mouse brain. Brains were also harvested at multiple time points to assess LITT effects on tight junction (TJ) integrity and transcytosis via immunofluorescence and transmission electron microscopy. Human glioblastoma tissues were …


Improving Infant Health Equity: What Have We Learned, What Do We Do, Dewayne M Pursley, F Sessions Cole Jul 2026

Improving Infant Health Equity: What Have We Learned, What Do We Do, Dewayne M Pursley, F Sessions Cole

2020-Current year OA Pubs

The United States neonatal and infant mortality rates have declined substantially over the last six decades. Despite these reductions, significant racial disparities in mortality and other important outcomes have persisted. While increased risk of preterm birth is a major contributor to these differences, racial inequities in risk-adjusted outcomes such as gestational age-specific and major congenital anomaly-associated mortality remain. Race-specific differences in inter- and intra-neonatal intensive care unit (NICU) practices associated with worse outcomes for infants of color suggest opportunities for reducing these disparate health outcomes during and after NICU hospitalization. Identifying NICU-based contributing factors and implementing factor-specific improvement strategies can …

The Effect Of Vaccine Mandates On Disease Spread: Evidence From College Covid-19 Mandates, Riley K. Acton, Wenjia Cao, Emily E. Cook, Scott A. Imberman, Michael F. Lovenheim

Research Collection School Of Economics

Nearly 700 4-year U.S. colleges mandated students receive COVID-19 vaccinations in fall 2021. Using data on college policies and county health, we estimate how mandates affect surrounding communities. Event studies from August to November 2021 show that mandates covering all colleges in a county reduced COVID-19 deaths by 5.6 per 100,000 persons, a 4.6% reduction in the U.S. total during this period. Mandates reduced COVID cases by 504 and ICU admissions by 16.2 per 100,000, though we see no statistically significant impact on hospitalizations. Impacts are larger in counties with larger college populations and low estimated ex-ante student vaccination rates.


Influence Of Self-Reported Maternal Mental Health Diagnosis And Parenting Practice On Child Externalizing Behavior, Caitlin E. Smith Jul 2026

Influence Of Self-Reported Maternal Mental Health Diagnosis And Parenting Practice On Child Externalizing Behavior, Caitlin E. Smith

All-Inclusive List of Electronic Theses and Dissertations

Maternal psychopathology generally has been associated with greater likelihood of childhood pathology (e.g., Bellina et al., 2020) which is likely due to both genetic (e.g. heritability of mental health diagnoses) and environmental (e.g., parenting) influences. ADHD, in particular, is a disorder with a high heritability rate (Kuja-Halkola et al., 2015). Other parent mental health difficulties, such as anxiety or depression, can also influence parenting behavior as well as child behavior. Broadly, maternal psychiatric history is related to child ADHD symptom severity (López Seco et al., 2015). Positive parenting may be especially important when parenting a child with ADHD as positive …

Department of Medical Oncology Faculty Papers

The management of locally-advanced, resectable head and neck squamous cell carcinoma (HNSCC) is undergoing a major shift driven by the integration of neoadjuvant immunotherapy (nIO). The rationale for nIO lies in its administration within an immunologically active, treatment-naïve microenvironment that enhances immune priming and anti-tumor response. Despite encouraging clinical data, including the pivotal KEYNOTE-689 trial and multiple phase II studies, methodological heterogeneity in trial design, endpoint definitions, and response criteria currently hampers data comparability and the establishment of new standards of care. This expert narrative review proposes a structured framework for standardizing clinical, pathologic, imaging, and translational endpoints in HNSCC …

Antibiotic Administration After Previable Preterm Prelabor Rupture Of Membranes Is Associated With Prolonged Latency, Alexandra L Hammerquist, Alexander M Saucedo, Selina L Bowler, Mohan Pammi, Catherine Eppes, Ignatia Van Den Veyver, Michael D Jochum, Enrico R Barrozo

Duncan NRI Faculty and Staff Publications

Introduction: While antibiotics have been shown to increase the interval to delivery between rupture of membranes and delivery (latency) and improve neonatal outcomes after viable preterm prelabor rupture of membranes (PPROM), this has not been well investigated in the previable PPROM population. We aimed to investigate the association between antenatal antibiotics and latency following previable PPROM. Secondarily, we examined various maternal and neonatal outcomes. We hypothesized that the administration of antibiotics would prolong latency in pregnancies with previable PPROM.

Methods: Single-center retrospective cohort study that included pregnancies diagnosed with previable PPROM between 140/7 and 216/7 and delivered between 2012 and …

Center for Medical Ethics and Health Policy Staff Publications

Polygenic risk scores (PRS) estimate individuals' genetic risk for developing multifactorial conditions. Recent genome-wide association studies have enabled development of psychiatric PRS, which hold potential to streamline diagnosis and treatment of psychiatric conditions. As individuals with mental illness often identify concern about passing on psychiatric conditions as a key factor in family planning, some may also seek to use psychiatric PRS in reproductive decisions like childbearing or embryo selection for in vitro fertilization. Despite calls for increased regulation, there remains no clinical consensus on the utility of psychiatric PRS in reproductive contexts. Therefore, we conducted semi-structured interviews of adults with …

Hepatitis B In The Vaccine Era: Persistent Burden And Clinical Implications, Cherechi Nwabueze, Eunice Omeludike, Ridwan Ademola Lawal, Kedife Nwabueze

School of Medicine Publications

Hepatitis B virus (HBV) infection remains a leading global cause of advanced liver disease and imposes a substantial economic burden. Early prevention is critical, as perinatally acquired HBV carries a high risk of progression to cirrhosis or hepatocellular carcinoma (HCC). Hepatitis B vaccination has been proven effective in preventing cancer, yet coverage of the complete vaccine series remains suboptimal. This implementation gap perpetuates the clinical burden, manifesting decades later as hepatic decompensation and liver cancer. This narrative review synthesizes the current HBV landscape, highlighting how gaps in vaccination policy and delivery contribute to real-world gastrointestinal outcomes. By reframing HBV vaccination …

Challenge-Based Ex Vivo Immune Profiling Reveals Stimulus-Dependent Peripheral Immune Reprogramming In Alzheimer's Disease, C. A. Naranjo-Galvis, Jovanny Zabaleta, Ney Alliey Rodriguez, Luisa Matilde Salamanca-Duque

School of Medicine Publications

Altered immune function is increasingly recognized as a contributor to Alzheimer's disease (AD); however, it remains unclear whether peripheral immune alterations reflect constitutive inflammation or stimulus-dependent changes in immune responsiveness. Addressing this distinction is critical for understanding immune dysregulation in neurodegenerative diseases. In this study, we applied a challenge-based ex vivo immune profiling approach to characterize functional immune responsiveness in patients with AD and in cognitively healthy older adults. Peripheral blood mononuclear cells were exposed to defined innate, antigenic, and mitogenic stimuli, and cytokine and β-amyloid (Aβ) responses were quantified in culture supernatants. Diagnosis-by-stimulus interaction effects were assessed using generalized …

2020-Current year OA Pubs

BACKGROUND: Necrotizing enterocolitis (NEC) is a disorder in very low birth weight (VLBW, < 1500 g) infants, associated with significant morbidity and mortality. Earlier detection of NEC may improve outcomes. We hypothesized that NEC's physiological signature resembles that of sepsis and that our model developed for sepsis, the Pulse Oximetry Warning System (POWS), would also predict NEC.

OBJECTIVES: Assess relationships between continuous heart rate (HR) and oxygen saturation (SpO

METHODS: In a retrospective multicenter analysis, we studied VLBW infants at four level IV NICUs, identifying cases of late-onset sepsis (LOS) and NEC (Bell stages 2 or 3). Using HR and SpO

RESULTS: Among 3914 infants evaluated, 5% had NEC and 13% had LOS. Cardiorespiratory data analysis showed that HR/SpO

CONCLUSION: NEC shares a cardiorespiratory signature with LOS. POWS predicted NEC with a dynamic rise before clinical diagnosis.

IMPACT: A cardiorespiratory early warning score analyzing …
