Objective Oculomotor, Vestibular, Reaction Time, And Cognitive Signatures Of Vestibular Migraine, Claire E. J. Ceriani, Alexandr Braverman, Alexander Kiderman

Department of Neurology Faculty Papers

OBJECTIVE: To evaluate oculomotor, vestibular, reaction time, and cognitive (OVRT-C) function in patients with vestibular migraine (VM) using objective eye-tracking-based metrics and to identify patterns of dysfunction relative to healthy controls.

BACKGROUND: Vestibular migraine is a common yet underdiagnosed cause of vertigo. Diagnosis remains primarily clinical, because objective neurologic and vestibular findings are often absent or inconsistent. Quantitative methods capable of capturing the multisystem manifestations of VM may improve objective characterization of the disorder.

METHODS: Participants with a clinical diagnosis of vestibular migraine were recruited from a tertiary headache center and assessed using a battery of OVRT-C tests administered with …

MCU, originally known as CCDC109A, is widely recognized as the gene responsible for encoding a pore-forming subunit of a Ca2+-selective channel, mitochondrial Ca2+ uniporter complex (mtCUC). While MCU expression is typically highly mitochondrial-specific, we report here a protein variant derived from the MCU gene, termed MCU-S, which lacks the mitochondria-targeting sequence (MTS) and forms a Ca2+-permeable channel outside of mitochondria. The mRNA of MCU-S was ubiquitously expressed in all cell types/tissues tested, with particularly high expression in human platelets. MCU-S protein formed Ca2+ channels at the plasma membrane, which exhibited similar channel properties to those observed in mtCUC. MCU-S channels …

Factors Associated With Vaping Frequency Among University Students, Oluwatosin Marylyn Oduneye

Masters Theses

Electronic cigarette use among university students is a growing public health concern, with approximately 20-25% reporting current use. Despite extensive research on vaping initiation, factors associated with vaping frequency among established users remain understudied. This study examined stress-coping mechanisms, peer influence, and health risk perceptions as predictors of vaping frequency, guided by Bandura's Social Cognitive Theory (SCT). A quantitative cross-sectional survey was administered via Microsoft Forms to 399 university students aged 21-25 with recent vaping experience, recruited nationally through campus flyers and online platforms. Multiple linear regression was conducted in SAS OnDemand for Academics, with stress-coping, peer influence, and health …

Repurposing Semaglutide As An Adjunctive Treatment For Cocaine Use Disorder: Protocol For A Randomised Controlled Trial, Luba Yammine, Francesco Versace, Charles E Green, Heather E Webber, Jin Ho Yoon, Absalon D Gutierrez, Samuel J Leonard, Michael F Weaver, Joy Schmitz

Faculty, Staff and Student Publications

Introduction: Cocaine use disorder (CUD) is a significant public health concern in the USA, with considerable prevalence and mortality and no Food and Drug Administration (FDA)-approved pharmacotherapies. Recent advances in addiction science emphasise the need for novel, mechanism-based treatments. Glucagon-like peptide-1 receptor agonists, such as semaglutide, have shown promise in modulating reward-related behaviours and may offer therapeutic benefits for CUD. We present a study protocol evaluating semaglutide, as an adjunct to cognitive behavioural therapy (CBT), as a novel approach for treating CUD.

Methods and analysis: This is a randomised, double-blind, placebo-controlled trial enrolling 75 treatment-seeking adults with CUD. Participants will …

Faculty, Staff and Students Publications

Cisplatin (DDP)-based chemotherapy serves as a foundational cornerstone in the clinical management of esophageal squamous cell carcinoma (ESCC). However, intrinsic or acquired resistance to DDP persists as a significant clinical challenge, severely undermining therapeutic efficacy and contributing to unfavorable patient prognoses. Through functional screening with a CRISPR/Cas9 knockout library, transcriptomic profiling of cisplatin-resistant cell lines and clinical specimens, and in vitro/in vivo validation assays, we identified PHKG2 as a key mediator of cisplatin resistance in ESCC. Mechanistically, PHKG2-mediated cisplatin resistance is driven by the phosphorylation of IGF2BP3 at residues T225 and T306. This post-translational modification enhances IGF2BP3 phase separation, thereby …

Pr Interval Alternans And The Mystery Of Inverse Decremental Conduction, Alyssa Zakala, Mohammed Hussein Kamareddine, Farah Olleik, Ali Keramati, Gan-Xin Yan

Department of Medicine Faculty Papers

CASE SUMMARY: A 73-year-old man with severe aortic stenosis and preexisting right bundle branch block (RBBB) underwent transcatheter aortic valve replacement. Postprocedural day 4 mobile cardiac outpatient telemetry revealed intermittent atrioventricular block. A 12-lead electrocardiogram obtained in the emergency department revealed PR interval alternans with RBBB, with longer PR following longer preceding RP intervals, and shorter PR following shorter RP intervals. He suddenly experienced cardiac arrest due to proximal atrioventricular block, requiring cardiopulmonary resuscitation.

TAKE-HOME MESSAGES: Inverse decremental conduction, known as Yan conduction, demonstrates an inverse relationship between conduction time and frequency of upstream stimulation. Inverse decremental conduction within the …

When Qtc Shrinks After Rhythm Conversion, Mohammed Hussein Kamareddine, Alyssa Zakala, Farid Farkouh, Ibrahim Alameh, Gan-Xin Yan

Department of Medicine Faculty Papers

CASE SUMMARY: An 83-year-old man with a history of atrial fibrillation on amiodarone therapy was admitted for direct-current cardioversion because of recurrent atrial fibrillation with a ventricular rate of approximately 105 beats per minute. Cardioversion successfully restored sinus rhythm. Postcardioversion 12-lead electrocardiography revealed an unexpectedly short QTc of 344 ms despite chronic treatment with a QT-prolonging agent. This finding was attributed to QT hysteresis, reflecting delayed adaptation of ventricular repolarization to the abrupt reduction in heart rate after rhythm conversion.

TAKE-HOME MESSAGE: QT hysteresis can result in transient QTc shortening and has important implications for interpretation of QT intervals during …

Local dendritic computations are thought to critically influence neuronal signaling and plasticity yet remain largely unexplored in vivo due to challenges in stably imaging small structures at ultrafast timescales. We developed a 3D real-time motion correction platform for movement-stabilized, ultrafast two-photon voltage imaging. By co-labeling CA1 pyramidal neurons with voltage and calcium indicators, we simultaneously measured somato-dendritic and electro-calcium coupling at multiple dendritic sites. We characterized isolated dendritic spikes and distance-dependent backpropagation of naturally occurring and photostimulation-evoked bursts and single spikes. We found that bursts backpropagated more reliably than single spikes, validated that somato-dendritic coupling decreases with distance from soma, …

Brain-Wide Structural Markers Of Familial And Clinical Risk For Bipolar Disorder In Youth, Danella M Hafeman, Jamie Feldman, John Merranko, Mary L Phillips, Boris Birmaher, Si Gao, Yizhou Ma, Peter Kochunov

Faculty, Staff and Student Publications

Background: Bipolar Disorder (BD) is a severe mental illness, often emerging during adolescence, that is associated with significant psychosocial impairment. BD risk is elevated in offspring of affected parents, particularly those with antecedent symptoms (e.g., mood lability, subthreshold manic symptoms). However, robust, replicable brain-based markers of risk in this population are lacking. We assessed the degree to which the Regional Vulnerability Index for BD (RVI-BD), quantified as an individual's brain-wide similarity to BD patterns derived from meta-analytic studies, is elevated in youth at familial risk and correlates with symptom predictors of BD.

Methods: We recruited n=82 adolescents (10-15 years old), …

Exceptional Response Of Radiotherapy-Naïve Cranial Meningiomas To Dual Immune Checkpoint Blockade In Bap1 Tumor Predisposition Syndrome, Gary Gallia, Christine Hann, Calixto-Hope Lucas, Licia Pacheco Luna, David Kamson, Takami Sato

Department of Medical Oncology Faculty Papers

Meningiomas are the most common primary central nervous system tumors, and while most are benign, atypical and anaplastic variants frequently recur and have limited effective treatment options. Recent trials of PD-1 blockade in unselected meningioma cohorts have demonstrated modest activity, with low objective response rates. These findings highlight the need to identify molecular biomarkers that may predict immunotherapy sensitivity in this disease. BRCA1-associated protein 1 (BAP1) is a tumor suppressor critical for chromatin regulation and DNA repair, and germline pathogenic variants cause BAP1 tumor predisposition syndrome (BAP1-TPDS), a hereditary cancer syndrome characterized by uveal melanoma, mesothelioma, renal cell carcinoma, meningioma, …
