A Narrative Review Of Bertolotti's Syndrome: Etiology, Classification, Diagnosis, And Treatment, Matyas Abel Tsegaye, Andrea Muffly

Rehabilitation Sciences Faculty Publications

Bertolotti's syndrome is a congenital condition characterized by chronic low back pain stemming from a lumbosacral transitional vertebra (LSTV). Because the condition is frequently overlooked, patients often face years of delayed diagnosis before the true source of their pain is identified. Furthermore, current information regarding the biological origins and clinical management of the condition remain scattered. To address this knowledge gap, this narrative review aims to provide a comprehensive overview of Bertolotti’s syndrome by consolidating these disparate sources and suggesting new connections. We synthesize the latest understanding of this condition, ranging from its genetic origins to modern clinical management. We …

The Sequence (S) Index As A Marker Of Diminished Step-To-Step Transition Efficiency In Older Adults, Elham Alijanpour, Ashwini Kulkarni, Peter G. Adamczyk, Daniel M. Russell

Rehabilitation Sciences Faculty Publications

Introduction: Age-related declines in walking efficiency are often attributed to musculoskeletal and neuromuscular changes, yet the mechanisms underlying these inefficiencies remain poorly understood. One key contributor is the step-to-step transition (STST), during which the center of mass (CoM) is redirected between limbs. The Sequence (S) index quantifies the temporal overlap between push-off and collision forces during STST, with higher values indicating greater mechanical energy loss. This study investigated whether aging affects STST efficiency, as quantified by the S index, and examined the timing and impulse characteristics underlying observed differences.

Methods: Thirteen young and eleven older healthy adults walked at five …

Nonlinear Differences In Postural Sway Across Attentional Focus Conditions In Individuals With And Without Anterior Cruciate Ligament Reconstruction, Natalie L. Ferguson, Brian L. Cone, Christopher K. Rhea, Anne Beethe, Breanna Studenka

Rehabilitation Sciences Faculty Publications

BACKGROUND: The structure of variability in postural sway reflects the adaptability and health of the postural control system. Entropy quantifies this structure by measuring the regularity of repeated fluctuations over time. Although entropy has been used to examine sway in neurological populations, little is known about how sway complexity changes following anterior cruciate ligament reconstruction (ACLR). Attentional focus may also influence postural control, with external focus typically promoting more efficient and automatic regulation than internal focus.

AIM: To examine how attentional focus (internal vs. external) influences the structure of postural sway in individuals with and without ACLR.

METHODS: Forty-three participants …

Across available cohorts, load-induced deformation was the …

Multisystem Predictors Of Dynamic Gait Stability Across Fall Risk In Older Adults, Ashwini Kulkarni, Neda Moghim, Ross Gore, Soumya Banerjee, Christopher K. Rhea, Brittany Samulski

Rehabilitation Sciences Faculty Publications

Gait stability arises from interactions between physiological, cognitive, and psychological systems, yet these domains are often assessed in isolation. This study examined multisystem predictors of anteroposterior margin of stability during walking (MoSAP) in community-dwelling older adults. Of 340 participants, 143 were retained after data quality screening (105 females; age: 70.8 ± 7.8 years). Participants completed the Physiological Profile Assessment (PPA), cognitive testing using Montreal Cognitive Assessment (MoCA), fear-of-falling evaluations using Modified Falls Efficacy Scale (MFES) and a biomechanical gait assessment during preferred and fast speeds. Participants were stratified into four PPA-based fall-risk groups: low, mild, moderate, and high risk. MoSAP …

Atrial Fibrillation Detection From At-Rest Ppg Signals Using An Sdof-Tf Method, Mamun Hasan, Zhili Hao

Mechanical & Aerospace Engineering Faculty Publications

At-rest PPG signals have been explored for detecting atrial fibrillation (AF), yet current signal-processing techniques do not achieve perfect accuracy even under low-motion artifact (MA) conditions. This study evaluates the effectiveness of a single-degree-of-freedom time–frequency (SDOF-TF) method in analyzing at-rest PPG signals for AF detection. The method leverages the influence of MA on the instant parameters of each harmonic, which is identified using an SDOF model in which the tissue–contact–sensor (TCS) stack is treated as an SDOF system. In this model, MA induces baseline drift and time-varying system parameters. The SDOF-TF method enables the quantification and removal of MA and …

Aim: This study investigates the feasibility of using radial and carotid arterial pulse signals to assess cardiovascular (CV) function at rest and during post-exercise recovery in a heart transplant (HTx) patient. Method: Two micro-fabricated tactile sensors were used to simultaneously acquire arterial pulse signals at the radial artery (RA) and carotid artery (CA). Measurements were taken at rest and at multiple time points post-exercise on three subjects: an HTx patient, a percutaneous coronary intervention (PCI; coronary stent) patient and a healthy control. An SDOF-TF-based time-frequency analysis algorithm was applied to extract a comprehensive set of CV parameters, including heart rate …

Simulating Social Attitudes With Llms: Accuracy, Demographic Effects, And Refusal Behavior In The Sensitive Domain Of Suicide Prevention, Cristina J. Perez, Michael P. Vasquez Jr., Philippe J. Giabbanelli, Patrick Y. Wu

VMASC Publications

Large language models (LLMs) are increasingly used to simulate public opinion, yet their validity in sensitive policy domains remains underexplored. We evaluate whether LLMs can reproduce attitudes toward suicide prevention policies using 32 questions drawn from seven nationally representative U.S. surveys (2023-2025). We systematically vary demographic conditioning (race/ethnicity, gender, age, education, income, party), prompt framing (direct elicitation, respondent embodiment, specialist embodiment), and model architecture (GPT-5 Nano, DeepSeek V3.2, Meta Llama 3.1 8B, Mistral Small 24B). Across 811,560 prompts, the mean absolute error—the average gap between predicted and human response distributions—is 23 percentage points. We also find that LLM responses to …

Estrogen Deprivation During Primate (Papio Anubis) Pregnancy: Impact On Systemic Microvascular Flow And Cardiovascular Development And Function After Birth In Offspring, Sifa Turan, Jeffery S. Babischkin, Graham W. Aberdeen, Gerald J. Pepe, Eugene D. Albrecht

Department of Biomedical and Translational Sciences Faculty Publications

Background

Suppressing estradiol (E₂) during baboon pregnancy lowers offspring skeletal muscle capillary density, vital for insulin-mediated glucose uptake, and induces insulin resistance. We examined whether E₂ deprivation also impairs microvascular flow and cardiac function.

Methods

Offspring of untreated baboons, letrozole-treated baboons, or letrozole plus E₂ (maternal s.c. injections during the second half of gestation) underwent contrast-enhanced microbubble ultrasonography to quantify microvessel flow and echocardiography to assess cardiac performance.

Results

Letrozole reduced maternal serum E₂ by 95% (p <  0.01). In letrozole offspring, microbubble flux rate (β) fell 55% (p <  0.02), replenishment was 5 s slower (p <  0.03), and microvessel flow declined 40% (p = 0.05); all were restored by added E₂. Indices of systolic (isovolumic contraction), diastolic (isovolumic relaxation), global performance (Tei index), and cardiac output were unchanged.

Conclusion

Prolonged gestational E₂ deprivation programs a reduction in microvascular flow without altering cardiac function; maternal E₂ prevents this, supporting E₂'s role in …

Comparative Mass Spectrometry Analysis Of High And Low Centrifugation Extracellular Vesicle (Ev) Pellets From Healthy Urine Following Tamm-Horsfall Protein Removal, Dana Bielopolski, Luca Musante, Henrik Molina, Douglas Barrows, Samantha Upson, Lifang Yang, Thomas Carrol, Jonathan N. Tobin, Rhonda G. Kost, U. Erdbrügger

Department of Biomedical and Translational Sciences Faculty Publications

Objectives

Urinary extracellular vesicles (uEVs) are potential biomarkers for renal physiology and disease. Their isolation is challenged by Tamm-Horsfall protein (THP) contamination, particularly in high-speed ultracentrifugation (P100) fractions. Low-speed (P20) fractions contain biologically relevant uEVs, yet their proteomic composition is underexplored. This study evaluates strategies for THP removal to optimize mass spectrometry analysis and characterizes P20 and P100 uEV proteomes and its combination in healthy urine.

Methods

Urine from a healthy volunteer was processed via sequential centrifugation at 21,200 g (P20) and 164,244 g (P100). THP removal was performed using low ionic strength buffer (P20) and size-exclusion chromatography (P100). Western …

The T-cell receptor (TCR) and the CD3 differentiation antigen on effector T cells and HLA on …

Bayesian Multivariate Modelling Of Lone Star (Amblyomma Americanum) Tick Life Stage Abundance And Temporal Trends To Inform Public Health Risk In Virginia, Thabo Lephoto, Henry Mwambi, Oliver Bodhlyera, Holly Gaff

Biological Sciences Faculty Publications

The increasing abundance of ticks poses a growing public health concern due to heightened human exposure to tick bites. The lone star tick (Amblyomma americanum: Ixodida: Ixodidae), a common human-biting species in the United States, has expanded its range in recent years. However, how its different life stages vary across time, habitats, and locations remains insufficiently understood. We analyzed tick abundance data collected in southeastern Virginia between 2009 and 2018, focusing on larval, nymphal, and adult life stages. A Bayesian multivariate modelling framework was used to examine seasonal patterns, habitat effects, spatial variation, and biological links between life stages. Two …

Endothelin-1 In The Failing Fontan: Pathobiology, Precision Therapeutics, And Future Trial Design, Iman Maiza

Department of Pediatrics Faculty Publications

The Fontan circulation, devised as definitive palliation for single-ventricle congenital heart disease, imposes systemic venous hypertension, loss of pulmonary arterial pulsatility, and restricted preload reserve. These hemodynamic trade-offs progressively injure the pulmonary vasculature, liver, and lymphatic system, producing late morbidities including elevated pulmonary vascular resistance, Fontan-associated liver disease (FALD), protein-losing enteropathy, and arrhythmias. Endothelin-1 (ET-1), a potent vasoconstrictor and profibrotic mediator, plausibly unifies these complications. Mechanistic studies demonstrate ET-1 upregulation in failed Fontan lungs, activating PLC–Ca²⁺, RhoA/ROCK, and MAPK/ERK cascades to drive vasoconstriction and remodeling. In cirrhotic livers, ET-1 localizes to stellate cells, promoting contraction and fibrogenesis, mechanisms biologically relevant …

Sociology & Criminal Justice Faculty Publications

Intimate partner violence (IPV) is a recurring social problem that has individual, interpersonal, community, and societal level consequences necessitating interdisciplinary knowledge and a holistic, systemic approach for prevention. Recent research on IPV indicates the need to identify the implications of the COVID-19 pandemic for IPV risk and subsequent consequences to inform mitigation solutions. Using a mixed-methods design, this rapid assessment research aims to address an existing gap by gathering primary data on the perceived risk and protective factors in addressing IPV through interviews, focus group discussions (n = 102), and surveys (n = 324) from a purposive sample of victim …

[Review Of The Book The Prescription-To-Prison Pipeline: The Medicalization And Criminalization Of Pain, By M. Smirnova], Hayley Jackey

Sociology & Criminal Justice Faculty Publications

[Introduction] Smirnova’s The Prescription-to-Prison Pipeline offers a critical examination of the impacts of prescription drugs as well as the over-policing and policies created to push individuals into the carceral system rather than providing other options for assistance. Smirnova further captures the social inequalities of race and class of those encased in this pipeline. Within this understanding of the detriment that the system, medical providers, and society place on those who use substances, Smirnova’s use of interviews allows for a clear understanding of how these systems work in conjunction to uphold the pipeline.

Confessions In Cases Of Child Physical Abuse - A Capnet Study, Margaret R. Russell, Antoinette L. Laskey, Henry T. Puls, Suzanne P. Starling, Joanne N. Wood, Daniel M. Lindberg, Nancy S. Harper, Caitlin R. Mcnamara, Angela N. Bachim, Farah W. Brink, Lori D. Frasier, James D. Anderst, Porcia Vaughn, Kristine A. Campbell

Department of Pediatrics Faculty Publications

Objective

Prior research on confessions of physical abuse (PA) has explored mechanisms of injury. Little is known about conditions supporting a confession of abuse or how confessions may influence case outcomes.

Methods

This cross-sectional study of suspected PA in children age < 10 years at 10 centers participating in CAPNET, a multicenter child PA research network, included children with in-person Child Abuse Pediatrics (CAP) consultations between Feb 2021-Dec 2022 and excluded children without injury. Our focus was a confession of inflicted injury known to the CAP during clinical involvement. We compared child and clinical characteristics, out-of-home (OOH) placements, and arrests between cases with and without confessions. Multivariable models using generalized estimating equations (GEE) produced adjusted predicted probabilities (APP) clustering by CAPNET site.

Results

Confessions were known to CAPs in 115/4297 (2.7%) cases, with significant site variability. In a multivariable GEE model, confessions were more likely in cases with injuries with high-specificity for abuse (APP 6.0% vs 1.5%, p< 0.001), near-fatality (APP 5.5% vs 2.3%, p< 0.001), and older children (APP 4.8% vs 2.5%, p = 0.025). OOH placements and arrests were more common in cases with confessions. CAP awareness of confessions, OOH placements, and arrests did not follow racial or ethnic patterns seen in the US child welfare system. Lower socioeconomic status was associated with OOH placements and arrests but not CAP awareness of confessions.

Conclusions

Our findings highlight differences in case characteristics and outcomes where a confession is known to the CAP and raise questions about agency …

Dementia Incidence In Patients With Prurigo Nodularis: An Observational Retrospective Cohort Study, Madison P. Olexson, Ana Ormaza Vera, Chunghwan Ro, Clinton W. Enos

Department Dermatology Faculty Publications

[Introduction] Prurigo nodularis (PN) is a chronic neuroinflammatory dermatosis of unknown etiology characterized by severely pruritic, symmetrically-distributed nodules with a negative impact on quality of life [1]. While some consider PN a primary idiopathic disorder, it often arises as a secondary manifestation of underlying conditions, including atopic dermatitis (AD), chronic kidney disease (CKD), human-immunodeficiency-virus (HIV), and thyroid disorders [2]. Although patients with PN are at higher risk for psychiatric comorbidities including depression, anxiety, and suicidal ideation [3] research which investigates associations between PN and neurodegenerative disorders is limited [4]. Moreover, emerging evidence implicating sustained systemic inflammation, characteristic of psoriasis and …

Central Centrifugal Cicatricial Alopecia In Pediatric Patients: A Retrospective Analysis, Radhika Gupta, Nikhita Perry, Noelle Desir, Iain Encarnacion, Jonathan Miles, Susan Taylor, Michelle Oboite, Temitaya Ogunleye

Department Dermatology Faculty Publications

[Introduction] Central centrifugal cicatricial alopecia (CCCA) is a scarring alopecia that predominantly affects middle-aged women of African descent.¹ It begins at the vertex scalp and expands centrifugally, and given that symptoms may be absent, many patients have scarring at presentation. CCCA is primarily described in adult populations, with limited reports of CCCA in children.²^-⁴ We aimed to characterize demographics, clinical findings, and histological features among pediatric patients with CCCA to facilitate earlier diagnoses, prior to irreversible alopecia.

Partial Post-Exposure Protection By Topical Inserts Containing Tenofovir Alafenamide Fumarate/Elvitegravir In A Macaque Model Of Rectal Simian Hiv (Shiv) Infection, Natalia Makarova, Tyana Singletary, M. Melissa Peet, Kristen Kelley, Ryan Johnson, Vivek Agrahari, Maria Mendoza, Yi Pan, Walid Heneine, Meredith R. Clark, J. Gerardo García Lerma, Gustavo F. Doncel, James W. Smith

CONRAD Publications

On-demand topical inserts for HIV prevention may be a good option for people who have a low frequency of sexual activity. We recently demonstrated in a preclinical macaque model that rectal application of inserts containing tenofovir alafenamide fumarate (TAF) and elvitegravir (EVG) conferred protection against SHIV infection (93% efficacy) when applied as pre-exposure prophylaxis 4 hours before SHIV exposure. Here, we show that the same inserts provide significant postexposure protection (82.9% efficacy) when applied 4 hours after SHIV exposure. Our findings further support the ongoing clinical development of TAF/EVG inserts for on-demand HIV prevention.

An Ensemble Classifier For Ordinal Outcomes In High-Dimensional Genomics Data, Heranga K. Rathnasekara, Sinjini Sikdar

Mathematics & Statistics Faculty Publications

Analysis of genomics data for predicting disease outcomes is a fast-growing field in medical research. There often exist categorical, specifically, ordinal outcomes that need to be predicted based on genomic profiles. This has led to recent development of some high-dimensional ordinal classification methods that can address the large dimensionality of the genomic covariate set. These high-dimensional ordinal models tend to vary widely in their performance depending on the data they are applied to and the evaluation criteria used. In this article, we outline an ensemble ordinal classifier that integrates different ordinal modeling approaches through bootstrap-based model evaluation, multi-metric performance assessment, …

Research and Infrastructure Service Enterprise (RISE) Faculty Publications

In the United States, Colorectal Cancer (CRC) is one of the most commonly diagnosed cancers and the third leading cause of death among non-Hispanic African American/Black (henceforth Black) men. Inadequate CRC knowledge leads to missing early warning signs, delaying prevention and increasing risk. Emerging adulthood (18-25) is a key period for building healthy behaviors and addressing barriers to CRC knowledge in addition to understanding attitudes and practices to CRC screening. Psychosocial barriers - including social support, medical mistrust, and perceived racial discrimination - contribute to the lack of CRC knowledge among older Black men, yet emerging adult Black men remain …
