Quantitatively Assessing The Impact Of The Quality Of Snomed Ct Subtype Hierarchy On Cohort Queries, Xubing Hao, Xiaojin Li, Yan Huang, Jay Shi, Rashmie Abeysinghe, Cui Tao, Kirk Roberts, Guo-Qiang Zhang, Licong Cui

Faculty, Staff and Student Publications

Objective: SNOMED CT provides a standardized terminology for clinical concepts, allowing cohort queries over heterogeneous clinical data including Electronic Health Records (EHRs). While it is intuitive that missing and inaccurate subtype (or is-a) relations in SNOMED CT reduce the recall and precision of cohort queries, the extent of these impacts has not been formally assessed. This study fills this gap by developing quantitative metrics to measure these impacts and performing statistical analysis on their significance.

Material and methods: We used the Optum de-identified COVID-19 Electronic Health Record dataset. We defined micro-averaged and macro-averaged recall and precision metrics to assess the …

Faculty, Staff and Student Publications

Comorbidities are common in Parkinson’s disease and significantly impact the disease progression and management. While polygenic scores have been widely used to assess genetic risk for complex diseases, their role in comorbidity presentation in Parkinson’s disease remains unclear. This study investigates whether genetic predisposition to comorbidities, as measured by polygenic scores, differs between individuals with Parkinson’s disease and the general population and explores how genetic risk influences disease onset and sex-related differences. We analysed data from 4144 individuals with Parkinson’s disease and 370 480 individuals from the general population in the UK Biobank, focusing on four comorbidities with high-quality genome-wide …

What Time Is It? It Is 8 And 1/2 Time: A Rare Case Of Ischemic Stroke Consistent With Eight-And-A-Half Syndrome, Jessica Daza, Marcelo Bedoya-Sommerkamp, Eunbee Cho, Celia Daza, Francisco Gomez, Fatimah Bello, Jia Lin

Faculty, Staff and Student Publications

Eight-and-a-half syndrome is a rare neuro-ophthalmic syndrome characterized by conjugate horizontal gaze palsy, ipsilateral internuclear ophthalmoplegia, and ipsilateral facial nerve palsy. It results from a lesion affecting the paramedian pontine reticular formation, the medial longitudinal fasciculus, and the abducens nucleus of the same side, at the level of the lower pons. We present a case of a 49-year-old man with 2-week diplopia and 3-day right-sided facial droop, drooling, and dysarthria. CT angiography of the head and neck revealed atherosclerotic disease, with decreased caliber of the basilar artery at the level of the pons. Brain MRI showed a subacute ischemic lesion …

Faculty, Staff and Student Publications

Objective: Middle meningeal artery embolization (MMAE) has emerged as a promising treatment, both as an adjunct to surgery and as a primary treatment for chronic subdural hematoma (cSDH). Here, we evaluate the efficacy of MMAE following surgery in reducing the likelihood of reoperation in patients requiring early introduction of antithrombotics.

Methods: From our prospectively collected registry of patients with cSDH, we identified patients treated with surgical evacuation, either in combination with or without MMAE. Patients were included if they had a clinical indication requiring early antithrombotics within 7 days of surgery. The primary outcome was the rate of reoperation. The …

The Future Of Parkinson’S Care: A Need To Expand Access, Sana Aslam, Anjail Z Sharrief, Samantha K Holden, Michelle Fullard, Jodi S Holtrop, Anna M Maw, Amy W Amara

Faculty, Staff and Student Publications

Parkinson's disease (PD) affects over one million Americans, with prevalence expected to double by 2040, creating rising challenges for healthcare systems. While neurologist-led care, particularly by movement disorder specialists (MDS), is associated with improved patient outcomes, only a small fraction of PD patients access this level of expertise. Many, various, barriers lead to delays or missed opportunities for advanced treatments such as deep brain stimulation and infusion therapies. This Perspective article issues a call to action for improving referral pathways and care coordination in PD, addressing both clinical and systems-level gaps. We propose several pragmatic strategies, including the development of …

Protecting Organs-At-Risk In Cancer Therapies Through Temporary Organ Displacement: A Comprehensive Review, Rance B Tino, Michael Li, Amirreza Heshmat, Ayush Suresh, Anasimone Guillaume, Kristy K Brock, Bruno C Odisio, Eugene J Koay

Faculty, Staff and Student Publications

Radiation therapy (RT) and locoregional ablation are cornerstones of modern oncology, yet their therapeutic potential is frequently limited by the challenge of sparing healthy organs-at-risk (OARs) from treatment-related complications. Temporary organ displacement (TOD) techniques directly address this issue by creating a physical separation using 'spacers' during treatment, thereby minimizing collateral damage while enhancing therapeutic precision. The clinical benefits, including improved tumor control, reduced morbidity, and enhanced survival, are documented across malignancies of the head and neck, thorax, abdomen, and pelvis. To create a unified framework for this evolving field, this comprehensive review provides a systematic classification of TOD techniques based …

While it is widely accepted that the nutritional management of the infant with chronic kidney disease (CKD) is paramount to achieve normal growth and development, nutritional management is also of importance beyond 1 year of age, particularly in toddlers, to support the delayed infantile stage of growth that may extend to 2-3 years of age. Puberty is also a vulnerable period when nutritional needs are higher to support the expected growth spurt. Inadequate nutritional intake throughout childhood can result in failure to achieve full adult height potential, and there is an increased risk for abnormal neurodevelopment. Conversely, the rising prevalence …

Role Of Mir-204 In Controlling Metabolic Functions Of The Subretinal Microglia, Yan Chen, Sarah E Bounds, Neloy Kundu, James Regun Karmoker, Yin Liu, Dongin Kim, Jiyang Cai

Faculty, Staff and Student Publications

Rationale: MicroRNA-204 (miR-204) is one of the most abundant miRNA species in the retinal pigment epithelium (RPE) and RPE-derived extracellular vesicles (EVs). Knockout (KO) of miR-204 leads to dysfunction and degeneration of both the RPE and the retina. In addition to previously reported retinal pathologies, we observed the accumulation of lipid-laden subretinal microglia in miR-204 KO mice. This study aimed to identify potential molecular targets of miR-204 involved in microglia lipid processing and to determine whether RPE-derived EVs can improve the function of miR-204-deficient retinal microglia.

Methods: Lipid accumulation in microglia was detected by staining with LipidTox, a fluorescent dye …

Advancing Alzheimer's Research By Improving Disease Modeling Of Secondary Tauopathy, Ethan R Roy, Wei Cao

Faculty, Staff and Student Publications

Despite decades of mechanistic investigation of Alzheimer's disease (AD), wide gaps exist in disease modeling, particularly the pathobiological arm of tau pathology. Relying on transgenic models expressing mutated forms of tau has contributed much knowledge about primary tauopathy, yet with limited relevance to human AD. To eliminate blind spots for basic and translational research, we review recent developments in this area and discuss key refinements toward next-generation AD-relevant tauopathy modeling.

Faculty, Staff and Student Publications

Poly(adenosine diphosphate ribose) polymerase (PARP) inhibitors, such as olaparib, talazoparib, rucaparib, and niraparib, comprise a therapeutic class that targets PARP proteins involved in DNA repair. Cancer cells with homologous recombination repair defects, particularly BRCA alterations, display enhanced sensitivity to these agents because of synthetic lethality induced by PARP inhibitors. These agents have significantly improved survival outcomes across various malignancies, initially gaining regulatory approval in ovarian cancer and subsequently in breast, pancreatic, and prostate cancers in different indications. This review offers a comprehensive clinical overview of PARP inhibitor approvals, emphasizing their efficacy across different cancers based on landmark phase 3 clinical …

Faculty, Staff and Student Publications

The variant single nucleotide polymorphism rs8104571 has been associated with poor outcomes following traumatic brain injury (TBI) and is most prevalent in those of African ancestry. This single nucleotide polymorphism (SNP) resides within a gene coding for the TRPM4 protein, which complexes with SUR1 protein to create a transmembrane ion channel and is believed to contribute to cellular swelling and cell death in neurological tissue. Our study evaluates the relationship between circulating TRPM4 and SUR1, rs8104571 genotype, and clinical outcome in TBI patients. Trauma patients with moderate to severe TBI were included in this retrospective study. rs8104571 genotyping and admission …

Mutation Of Conserved Mhc Class I Cytoplasmic Tyrosine Affects Cd8+ T Cell Priming, Effector Function, And Memory Response, Yimo Sun, Yitao Tang, Priscilla Ortiz, Barbara Nassif Rausseo, Barbara Pazdrak, Lama Elzohary, Arjun Katailiha, Amjad Talukder, Cassian Yee, Richard Eric Davis, Gregory Lizée

Faculty, Staff and Student Publications

The cytoplasmic domain of MHC class I (MHC-I) molecules contains a single, highly conserved tyrosine residue (Y320). In previous work, we found that mice expressing a Y320F-mutated form of H-2Kb had reduced capacity to generate Kb-restricted cytotoxic T lymphocyte (CTL) responses following viral infection, due at least in part to defects in endolysosomal trafficking of H-2Kb and antigen cross-presentation by dendritic cells (DCs). In this study, we investigated whether there are additional, post-presentation dependencies on Y320 for T cell priming. We engineered both human- and mouse-derived antigen-presenting cells (APCs) to express either wild-type MHC-I or variants of MHC-I containing Y320F …

The safe and effective delivery of curative cytotoxic chemotherapy for acute myeloid leukemia (AML) in patients receiving intermittent hemodialysis (IHD) for end-stage renal disease (ESRD) remains a clinical challenge; pharmacological and logistical barriers necessitate close interdisciplinary coordination. In this case, we report a 65-year-old female patient with chronic ESRD on IHD and newly diagnosed AML who achieved complete remission (CR) after treatment with fludarabine, idarubicin, and cytarabine plus venetoclax (i.e., FIA + venetoclax).

Autophagy Cargo Profiles In Skeletal Muscle During Starvation And Exercise, Mohd Farhan, Shangze Lyu, Trezze P Nguyen, Dakai Zhang, Hong Liang, Yong Zhou, Yu A An, Jun Wang, Hongyuan Yang, Guangwei Du, Yang Liu

Faculty, Staff and Student Publications

Autophagy is a cellular process to clear unwanted and dysfunctional cellular cargoes, which are sequestered in autophagosomes before their delivery to lysosomes for degradation. Autophagy cargo selection, mediated by cargo receptors, varies across cell types and conditions. Understanding the cargo features is essential for elucidating autophagy's function in specific physiological or pathological contexts. Here, we present a simple and rapid method for isolating LC3B-positive autophagosomes from the tissues of GFP-LC3 transgenic mice, a widely used autophagy reporter model, without relying on the complex ultracentrifugation steps required by traditional methods. When combined with quantitative proteomics, this approach enables efficient in vivo …
