Abnormalities In Sensorimotor Brain Function Are Related To Chronicity Of Low Back Pain, Jo Armour Smith, Rongwen Tain, Kelli G Sharp, Laura M Glynn, Linda R Van Dillen, Jesse V Jacobs, Steven C Cramer

2020-Current year OA Pubs

Maladaptive plasticity in the brain may contribute to chronic low back pain (LBP) and underlie the altered postural control of the lumbopelvic musculature that is evident in some individuals with LBP. We recently described an MRI-compatible leg-raise paradigm to measure brain activity associated with lumbopelvic postural control. The objective of this study was to compare brain function in young adults with and without a history of LBP and to determine relationships between brain function, pain, and postural control characteristics. We recruited 55 participants with a history of LBP, who were asymptomatic when studied, and 30 healthy controls. Postural control during …

Dysregulated Lactate Metabolism Synergizes With Als Genetic Risk Factors To Accelerate Motor Decline, Shweta Tendulkar, Tong Wu, Amy Strickland, Amber R. Hackett, Yurie Sato-Yamada, Xianrong Mao, Yo Sasaki, Jeffrey Milbrandt, A. Joseph Bloom, Aaron Diantonio

2020-Current year OA Pubs

Neurons rely on glial 'lactate shuttling' for metabolic support, which declines with aging and in neurodegenerative disease. Full disruption of lactate shuttling in peripheral nerves causes progressive axon degeneration, but we were interested to understand how partial disruption, a scenario more relevant to aging and disease, contributes to neurodegeneration risk. Pyruvate and lactate are interconverted by lactate dehydrogenases (LDHA and LDHB) in both lactate producing and consuming cells. We therefore began by investigating Ldhb knockout mice (loss of LDHA, the dominant LDH in liver and muscle, caused embryonic lethality), and discovered that they develop progressive neuromuscular junction atrophy and functional …

Near Infrared Fluorophore Specific For Annexin A2 Identifies Peripheral Nerve Injury In A Rodent Transection Model, Marie C Spezia, Christopher J Dy, Brooke Farrell, Ayan Iftikhar, Stephen Demartini, Ron Perez, Samuel Achilefu, David M Brogan

2020-Current year OA Pubs

INTRODUCTION: Peripheral nerve injuries (PNI) pose a major challenge in the intraoperative assessment of nerve viability. Wallerian degeneration (WD) is the degenerative process of axonal breakdown distal to the site of injury, with limited proximal extension, and progresses through spatiotemporally consistent stages facilitated by Schwann cell reprogramming and macrophage infiltration. We evaluated LS-301, a near-infrared (NIR) fluorophore previously used in human oncology trials, that targets phosphorylated annexin A2 (pANXA2), which is upregulated and redistributed to Schwann cell surfaces after nerve injury.

METHODS: Utilizing a sciatic nerve transection model in rats, LS-301 was compared with the untargeted control dye Cypate-3 using …

Neurofilament Light Chain But Not Glial Fibrillary Acidic Protein Serum Levels Are Elevated In Wolfram Syndrome, Matthew J Jansen, Heather M Lugar, Cris M Brown, Abby F Tang, Liam J Oiknine, Ling Chen, Jonathan M Koller, Brian A Gordon, Bess A Marshall, Fumihiko Urano, Tamara Hershey

2020-Current year OA Pubs

BACKGROUND: Wolfram syndrome is a rare genetic disorder caused by pathogenic variants in the

OBJECTIVE: To determine if serum NfL and/or GFAP levels are elevated in Wolfram syndrome compared to controls and whether they can serve as monitoring biomarkers.

METHODS: Serum NfL and GFAP levels were log

RESULTS: NfL levels were higher in the Wolfram group relative to all control groups (

CONCLUSION: Serum NfL elevation in Wolfram syndrome may reflect the ongoing, relatively slow neurodegeneration occurring in this disorder. However, without any correspondence between serum levels and currently used clinical and neuroimaging metrics, it has limited utility as a …

Modulating Efferocytosis In The Intestinal Epithelial Cells During Colorectal Cancer, Laura Boeckaerts, Tania Løve Aaes, Evi Scheirlinckx, Sze Men Choi, Yunus Incik, Amanda Gonçalves, Tino Hochepied, Lars Vereecke, Kodi S Ravichandran

2020-Current year OA Pubs

INTRODUCTION: Colorectal cancer (CRC) is the thirdmost common cancer and a leading cause of cancer deaths worldwide, with over 1.9 million cases diagnosed in 2022. Due to poor response to classical cancer treatments, CRC is associated with low survival rates. This creates an urgent need for better understanding of CRC pathology. Cell death occurs continuously in solid tumors, and is also induced acutely, during chemotherapy. Dead cells are cleared by phagocytes via 'efferocytosis', an anti-inflammatory process that can lead to immune escape and reduced therapeutic efficacy. We hypothesized that efferocytosis might contribute to tumor development and that manipulating this process …

Effects Of Anti-Parkinsonian Medication On Gait During Internal And External Rhythmic Auditory Cueing In Pd, Sidney T Baudendistel, Lauren E Tueth, Ryan P Duncan, Allison M Haussler, Liza Birov, Gammon M Earhart

2020-Current year OA Pubs

INTRODUCTION: External and internal auditory cueing strategies improve gait function, including velocity and stride length, in people with Parkinson disease (PD). Further, internal cueing can reduce gait variability, a measure associated with falls. In the present study, we asked whether the efficacy of external and internal rhythmic cues depends on dopaminergic status, i.e., OFF vs. ON medication. This question is relevant to the real-world use of cueing, as dopaminergic medication responsiveness fluctuates for individuals. We measured gait while participants with PD walked with an external cue (music playing aloud) and with an internal cue (mentally singing) in both OFF and …

"Using Theories" And "Doing Theory": Tool And Action Orientations To Theory At The Interface Of Public Health And Anthropology, Peter Taber, Eileen M Dryden, Jean M Hunleth, Linda S Kahn, Lance Laird, Teresa Winstead, Genevra F Murray

2020-Current year OA Pubs

The use of "theory" is a common concern in public health and anthropology. However, the term can have quite distinct meanings. In this piece, we seek to name and characterize some tendencies in anthropological theorizing that contribute to potential misunderstandings when communicating with non-anthropologist colleagues in public health. In particular, we highlight differences between the use of recognizable, named "theories" that often explicitly frame public health research and interventions, and the open-ended and context-specific work of "doing theory" sometimes referenced in anthropology. Observing the linguistic shifts entailed to refer to theory in each of these cases-"using theories" versus "doing theory"-we …

Sex Differences In Glycine Biosynthesis Drives Sex-Specific Responses To Combined Nutrient Deprivation And Pharmacological Inhibition In Brain Tumors, Camryn Marquez, Jianyun Lu, Kevin Cho, Shanshan Zhang, Jingqin Luo, Joshua B Rubin, Gary J Patti, Joseph E Ippolito

2020-Current year OA Pubs

BACKGROUND: Glioblastoma (GBM) is the deadliest brain tumor. Generally, male GBM occurs at higher incidence and demonstrates shorter overall survival compared to females. Targetable drivers of this phenomenon remain undisclosed, preventing the integration of sex differences into the design of targeted therapeutics.

METHODS: Here, we utilized metabolite tracing, pharmacological blockade, and nutrient deprivation to profile and target putative sex differences in cellular proliferation driven by the synthesis of glycine and nucleotides from glucose.

RESULTS: Utilizing an established murine model of GBM (

FINDINGS: These data suggest inhibition of

Nanoparticle Albumin-Bound Paclitaxel And Nivolumab For Pd-1 Inhibitor-Refractory Recurrent Or Metastatic Head And Neck Squamous-Cell Carcinoma, Douglas Adkins, Jessica C Ley, Christine Auberle, Brendan Knapp, Jesse Zaretsky, Jingxia Liu, Peter Oppelt

2020-Current year OA Pubs

INTRODUCTION: Standard therapy for PD-1 inhibitor-refractory recurrent or metastatic head and neck squamous-cell carcinoma (RM-HNSCC) has limited activity. Drugs bound to albumin selectively target cancer cells with upregulated macropinocytosis, a process driven by constitutively hyper-activated EGFR/RAS/PIK3CA signaling, which is common in HNSCC. Nanoparticle albumin-bound (nab)-paclitaxel is active in PD-1 inhibitor-naïve RM-HNSCC and alters immune cells to potentially prime tumor response and reverse resistance to PD-1 inhibitors.

METHODS: In a single-arm phase 2 trial, patients with PD-1 inhibitor-refractory RM-HNSCC received nab-paclitaxel and nivolumab given in 28-day cycles. The primary endpoint was objective response rate (ORR), using RECIST1.1. Key secondary endpoints were …

Brain amyloid-β (Aβ) pathology is a core feature of Alzheimer disease (AD) and can be quantified using positron emission tomography (PET). Cerebrospinal fluid (CSF) and plasma biomarkers detect abnormal Aβ, but it is unclear to what degree they can predict quantitative Aβ-PET. We explored plasma and CSF biomarkers in relation to Aβ-PET in the BioFINDER-2 study (N = 1053), and the BioFINDER-1 study (N = 238). We developed a machine learning pipeline to predict Aβ-PET using CSF and plasma measures. The best models achieved R

Major depressive disorder (MDD) is linked to a higher risk of premature aging, but the mechanisms underlying this association remain unclear. Using data from two population cohorts (UK Biobank and Finnish Twin Cohort), we evaluate the relationship between systemic and organ-specific proteomic and epigenetic aging acceleration and MDD. A lifetime history of MDD was associated with accelerated proteomic aging at both systemic and organ-specific levels-including the brain-in both cohorts, with stronger associations than those observed with systemic epigenetic aging. Systemic and brain-specific proteomic aging acceleration were linked to higher risks of incident MDD and a greater risk of Alzheimer's disease, …

2020-Current year OA Pubs

BACKGROUND: Despite advances in endocrine therapy, patients with hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative (HER2-) early breast cancer (eBC) remain at risk of recurrence (ROR). Chemotherapy is often used in high-risk cases, but not all patients benefit.

OBJECTIVES: To evaluate whether chemotherapy can be safely omitted in patients with stage II, grade 2/3 HR+/HER2- eBC who convert to low genomic risk (ROR-low) following neoadjuvant ribociclib plus letrozole.

METHODS: RIBOLARIS (NCT05296746) is an open-label, multicenter phase II trial in patients with stage II, grade 2 or 3, HR+/HER2- eBC defined as high risk based on a Ki-67 index ⩾20% …

Relationship Among Sleep Disturbance, Stress, And Suicidal Ideation In Clinical High Risk For Psychosis, Heather M Wastler, Daniel Mamah, Et Al.

2020-Current year OA Pubs

BACKGROUND AND HYPOTHESIS: Sleep disturbance is a well-established risk factor for suicide, though few studies to date have examined whether sleep disturbance contributes to suicide risk among individuals at clinical high risk for psychosis (CHR). The current study addressed this gap in the literature. We hypothesized that sleep disturbance would have a unique relationship with suicidal ideation/attempts when accounting for other variables in the model. We also hypothesized that the interaction between sleep disturbance/attenuated positive symptoms and sleep disturbance/stress would be related to suicidal ideation/attempts in CHR.

STUDY DESIGN: The current study used data generated by the Accelerating Medicines Partnership® …

Streamlining Eligibility Assessment For Alzheimer’S Disease-Modifying Therapies: Prediction Of Mmse Scores Using The Digital Clock And Recall, Emma Chen, John Showalter, David Bates, Alvaro Pascual-Leone, Sean Tobyne

Faculty, Staff and Students Publications

           Introduction: The eligibility of anti-amyloid disease-modifying therapies (DMTs) and their integration into clinical practice in some institutions requires a specific range of Mini-Mental State Examination (MMSE) scores. Reliance on this pencil-and-paper psychometric instrument imposes operational burdens and risks of perpetuating health disparities, given the test's known educational and cultural biases. This study evaluates the efficacy of the Digital Clock and Recall (DCR™)-a rapid, FDA-listed digital cognitive assessment-to crosswalk to MMSE scores using machine learning, thereby offering a faster, scalable, and equitable mechanism for patient triage.

Methods: We conducted a retrospective analysis using data from the multi-site Bio-Hermes-001 (BH) study ( …

Bioinformatic Identification And Analysis Of Shared Splicing Errors In Myotonic Dystrophy Type (Dm1) And Fuchs' Endothelial Corneal Dystrophy (Fecd), Carter I. Wilkins

Electronic Theses & Dissertations (2024 - present)

Myotonic dystrophy type 1 (DM1) is an autosomal dominant form of muscular dystrophy, and it is the most common form of adult-onset muscular dystrophy. The disease is the result of CTG trinucleotide repeats (TNR) in the 3’UTR of the dystrophia myotonica protein kinase (DMPK) gene. This produces toxic RNA hairpin structures by CUG repeat expansions that sequester proteins–most relevantly muscleblind-like 1 (MBNL)–that regulate alternative RNA splicing. The missplicing of a wide variety of genes results in the symptoms such as myotonia (rigidity of the muscles), atrophy, and cardiac failure.

Fuchs’ Endothelial Corneal Dystrophy (FECD) is characterized by progressive loss and …
