Faculty, Staff and Student Publications

Objectives

Sudden unexpected death in epilepsy (SUDEP) is a leading cause of death for patients with epilepsy; however, the pathophysiology remains unclear. Focal‐to‐bilateral tonic–clonic seizures (FBTCS) are a major risk factor, and centrally‐mediated respiratory depression may increase the risk further. Here, we determined the volume and microstructure of the amygdala, a key structure that can trigger apnea in people with focal epilepsy, stratified by the presence or absence of FBTCS, ictal central apnea (ICA), and post‐convulsive central apnea (PCCA).

Methods

Seventy‐three patients with focal impaired awareness seizures without FBTC seizures (FBTCneg group) and 30 with FBTCS (FBTCpos group) recorded during …

Spatial-Temporal Episodic Memory Modeling For Adls: Encoding, Retrieval, And Prediction, Xinjing Song, Di Wang, Chai Quek, Ah-Hwee Tan, Yanjiang Wang

Research Collection School Of Computing and Information Systems

Activities of daily living (ADLs) relate to people’s daily self-care activities, which reflect their living habits and lifestyle. A prior study presented a neural network model called STADLART for ADL routine learning. In this paper, we propose a cognitive model named Spatial-Temporal Episodic Memory for ADL (STEM-ADL), which extends STADLART to encode event sequences in the form of distributed episodic memory patterns. Specifically, STEM-ADL encodes each ADL and its associated contextual information as an event pattern and encodes all events in a day as an episode pattern. By explicitly encoding the temporal characteristics of events as activity gradient patterns, STEM-ADL …

Faculty, Staff and Student Publications

Background: The clinical diagnosis of manifest Huntington's disease (HD) relies on a high level of clinical confidence (99% confidence) of HD-consistent motor signs. Longitudinal data have reliably identified cognitive and behavioral dysfunction predating clinical motor diagnosis by up to 15 years. Reliance on motor signs to establish a diagnosis of HD increases risk of early misdiagnosis or delayed diagnosis. Clinical neuropsychologists are uniquely positioned to advise on the clinical application of the Movement Disorder Society Task Force's recently proposed non-motor diagnostic criteria for HD.

Objectives: To provide (1) a recommended clinical approach toward non-motor diagnostic criteria in persons with HD …

An Update On The Management Of Advanced Phase Chronic Myeloid Leukemia, Nicholas J Short, Jayastu Senapati, Elias Jabbour

Faculty, Staff and Student Publications

Purpose of review: While most patients with chronic myeloid leukemia (CML) present in a chronic phase and are expected to have a normal life expectancy, some patients present with or progress to a more aggressive accelerated phase (AP) or blast phase (BP) of CML. Herein, we discuss the diagnostic considerations of advanced phase CML and review its contemporary management.

Recent findings: Later-generation, more potent BCR::ABL1 tyrosine kinase inhibitors (TKIs) such as ponatinib may result in superior outcomes in patients with advanced phase CML. For CML-BP, combination approaches directed against the blast immunophenotype appear superior to TKI monotherapy. The role of …

Evaluation Of Potential Role Of R-Loop And G-Quadruplex Dna In The Fragility Of C-Myc During Chromosomal Translocation Associated With Burkitt's Lymphoma, Nitu Kumari, Kohal Das, Shivangi Sharma, Sumedha Dahal, Sagar Sanjiv Desai, Urbi Roy, Anju Sharma, Meghana Manjunath, Vidya Gopalakrishnan, S T Retheesh, Saniya M Javadekar, Bibha Choudhary, Sathees C Raghavan

t(8;14) translocation is the hallmark of Burkitt's lymphoma and results in c-MYC deregulation. During the translocation, c-MYC gene on chromosome 8 gets juxtaposed to the Ig switch regions on chromosome 14. Although the promoter of c-MYC has been investigated for its mechanism of fragility, little is known about other c-MYC breakpoint regions. We have analyzed the translocation break points at the exon 1/intron 1 of c-MYC locus from patients with Burkitt's lymphoma. Results showed that the breakpoint region, when present on a plasmid, could fold into an R-loop confirmation in a transcription-dependent manner. Sodium bisulfite modification assay revealed significant single-strandedness …

The Risk Index As A Basis For Risk/Benefit Analyses And Protocol Optimization In Diagnostic Nuclear Imaging, Juan C Ocampo Ramos, Lukas M Carter, Justin L Brown, Harry Marquis, Carlos F Uribe, Pat B Zanzonico, Wesley E Bolch, Adam L Kesner

Faculty, Staff and Student Publications

Background: Potential risk associated with low-dose radiation exposures is often expressed using the effective dose (E) quantity. Other risk-related quantities have been proposed as alternatives. The recently introduced risk index (RI) shares similarities with E but expands the metric to incorporate medical imaging-appropriate risks factors including patient-specific size, age, and sex.

Purpose: The aim of this work is to examine the RI metric for quantifying stochastic radiation risk and demonstrate its applications in nuclear imaging. The advantages in this improved metric may help the field progress toward stratified risk consideration in the course of patient management, improve efforts for procedure …

Droid: Dose-Ranging Approach To Optimizing Dose In Oncology Drug Development, Beibei Guo, Ying Yuan

Faculty, Staff and Student Publications

In the era of targeted therapy, there has been increasing concern about the development of oncology drugs based on the "more is better" paradigm, developed decades ago for chemotherapy. Recently, the US Food and Drug Administration (FDA) initiated Project Optimus to reform the dose optimization and dose selection paradigm in oncology drug development. To accommodate this paradigm shifting, we propose a dose-ranging approach to optimizing dose (DROID) for oncology trials with targeted drugs. DROID leverages the well-established dose-ranging study framework, which has been routinely used to develop non-oncology drugs for decades, and bridges it with established oncology dose-finding designs to …

The Clinicopathologic Features And Molecular Signatures Of Blastoid High-Grade B Cell Lymphoma, Not Otherwise Specified, Lianqun Qiu, Pei Lin, Mahsa Khanlari, Jie Xu, Evan N Cohen, Sofia Garces, Roberto N Miranda, Wei Wang, Hong Fang, Carlos E Bueso-Ramos, L Jeffrey Medeiros, Shaoying Li

Faculty, Staff and Student Publications

A small subset of high-grade B-cell lymphoma (HGBL) with blastoid morphology remains poorly understood. We assessed 55 cases of blastoid HGBL, not otherwise specified (NOS) and compared their clinicopathologic characteristics with those of 81 non-blastoid HGBL-NOS and 62 blastoid HGBL with MYC and BCL2, with or without BCL6 rearrangements (double/triple-hit lymphoma [D/THL]). Patients with blastoid HGBL-NOS showed similar clinicopathologic features to patients with blastoid D/THLs and non-blastoid HGBL-NOS, except more frequently with a history of low-grade B-cell lymphoma, bone marrow involvement, and BCL2 rearrangement (P < .05) compared to the latter. MYC rearrangement (MYC-R), detected in 40% of blastoid HGBL-NOS, was associated with aggressive clinicopathologic features and poorer overall survival, even worse than that of blastoid D/THL (P < .05). Transcriptome profiling revealed a distinct gene expression pattern with differentially expressed genes enriched in MYC and P53-targeted genes in MYC-R blastoid HGBL-NOS. Fifty-two percent of blastoid HGBL-NOS had a double hit-like signature, similar to non-blastoid HGBL-NOS (P = .73). The overall survival of the blastoid HGBL-NOS group was similar to that of the blastoid D/THL group but appeared poorer than that of its non-blastoid counterparts (P = .07). Taken together, blastoid HGBL-NOS is an aggressive B-cell lymphoma that shares overlapping clinicopathologic and genetic features with non-blastoid HGBL-NOS. MYC-R in patients with blastoid HGBL-NOS identifies a highly aggressive subgroup with distinct aggressive clinicopathologic features, unique molecular signatures, and a dismal clinical outcome.

Radiation-Induced Innate Neutrophil Response In Tumor Is Mediated By The Cxcls/Cxcr2 Axis, Faya Zhang, Oscar Mulvaney, Erica Salcedo, Subrata Manna, James Z Zhu, Tao Wang, Chul Ahn, Laurentiu M Pop, Raquibul Hannan

Faculty, Staff and Student Publications

The early events that lead to the inflammatory and immune-modulatory effects of radiation therapy (RT) in the tumor microenvironment (TME) after its DNA damage response activating the innate DNA-sensing pathways are largely unknown. Neutrophilic infiltration into the TME in response to RT is an early innate inflammatory response that occurs within 24-48 h. Using two different syngeneic murine tumor models (RM-9 and MC-38), we demonstrated that CXCR2 blockade significantly reduced RT-induced neutrophilic infiltration. CXCR2 blockade showed the same effects on RT-induced tumor inhibition and host survival as direct neutrophil depletion. Neutrophils highly and preferentially expressed CXCR2 compared to other immune …

Firearm Injury Prevention, Kelsey A B Gastineau, Sandra Mckay

Faculty, Staff and Student Publications

Firearms are the leading cause of death for US youth, overtaking motor vehicle collisions in 2020. Approximately 65% are due to homicide, 30% are due to suicide, 3.5% are due to unintentional injuries, 2% are undetermined intent, and 0.5% are from legal interventions. In homes with firearms, the likelihood of unintentional death, suicide, and homicide is three to four times higher than those without firearms. Secure storage of firearms, having them locked, unloaded, and separate from ammunition can prevent unintentional firearm injuries.

We incorporate tools for improving model performance such as incorporating a distance function, a physics-informed loss to enforce the law of mass conservation, and the Huber loss to learn patterns across heterogeneous velocity components of multiple dimensions. Results: The tools implemented together with our architecture achieved the best performance on …

Self-Supervised Pseudo Multi-Class Pre-Training For Unsupervised Anomaly Detection And Segmentation In Medical Images, Yu Tian, Fengbei Liu, Guansong Pang, Yuanhong Chen, Yuyuan Liu, Johan W. Verjans, Rajvinder Singh, Gustavo Carneiro

Research Collection School Of Computing and Information Systems

Unsupervised anomaly detection (UAD) methods are trained with normal (or healthy) images only, but during testing, they are able to classify normal and abnormal (or disease) images. UAD is an important medical image analysis (MIA) method to be applied in disease screening problems because the training sets available for those problems usually contain only normal images. However, the exclusive reliance on normal images may result in the learning of ineffective low-dimensional image representations that are not sensitive enough to detect and segment unseen abnormal lesions of varying size, appearance, and shape. Pre-training UAD methods with self-supervised learning, based on computer …

Combat Covid-19 At National Level Using Risk Stratification With Appropriate Intervention, Xuan Jin, Kar Way Tan

Research Collection School Of Computing and Information Systems

In the national battle against COVID-19, harnessing population-level big data is imperative, enabling authorities to devise effective care policies, allocate healthcare resources efficiently, and enact targeted interventions. Singapore adopted the Home Recovery Programme (HRP) in September 2021, diverting low-risk COVID-19 patients to home care to ease hospital burdens amid high vaccination rates and mild symptoms. While a patient's suitability for HRP could be assessed using broad-based criteria, integrating machine learning (ML) model becomes invaluable for identifying high-risk patients prone to severe illness, facilitating early medical assessment. Most prior studies have traditionally depended on clinical and laboratory data, necessitating initial clinic …

The Effect Of Maternal Obesity On The Regulation Of Gene Expression And Cell Fate During Embryonic Cortical Neurogenesis, Thilina Thejinda Alawathugoda

Dissertations

Neurodevelopmental disorders have their roots in multifaceted origins that manifest during the earliest stages of embryonic growth, often linked to sophisticated gene regulation dynamics. A perturbed metabolic environment, specifically owing to maternal obesity, can lead to dyslipidemia, subsequently threatening the optimal development of the embryonic central nervous system. Growing evidence suggests that such metabolic irregularities during pregnancy can alter neurogenesis pathways, thus predisposing the developing fetus to neurodevelopmental disorders. One of the primary avenues through which these disruptions may occur is through alterations in histone modifications resulting from fluctuations in the expression of histone modifying enzymes or the availability of …
