Encoding 3d Information In 2d Feature Maps For Brain Ct-Angiography, Uma M Lal-Trehan Estrada, Sunil Sheth, Arnau Oliver, Xavier Lladó, Luca Giancardo

Faculty, Staff and Student Publications

We propose learnable 3D pooling (L3P), a CNN module designed to compress 3D information into 2D feature maps using anisotropic convolutions and unidirectional max pooling. Specifically, we used L3P followed by a 2D network to generate predictions from 3D brain CT-Angiography (CTA) in the context of large vessel occlusion (LVO). To further demonstrate its versatility, we extended its application to 3D brain MRI analysis for brain age prediction. First, we designed an experiment to classify the LVO-affected hemisphere (left or right), projecting the input CTA into the sagittal plane, which allowed to assess the ability of L3P to encode the …

The Tweak/Fn14 Signaling Mediates Skeletal Muscle Wasting During Cancer Cachexia, Meiricris Tomaz Da Silva, Anirban Roy, Anh Tuan Vuong, Aniket S Joshi, Cristeena Josphien, Meghana V Trivedi, Sajedah M Hindi, Vihang A Narkar, Ashok Kumar

Faculty, Staff and Student Publications

Cancer cachexia is a multifactorial syndrome characterized by progressive skeletal muscle wasting. The TWEAK-Fn14 system regulates muscle mass in diverse conditions. However, its role in the regulation of muscle mass during cancer cachexia remains less understood. Here, we demonstrate that the levels of Fn14 are induced in skeletal muscle of multiple mouse models of cancer cachexia. Muscle-specific deletion of Fn14 reduces myofiber atrophy in mouse models of pancreatic and lung cancer cachexia. Silencing of Fn14 in KPC pancreatic cancer cells prior to their implantation in mice attenuates tumor growth without affecting myofiber size. Muscle-specific deletion of Fn14 reduces the gene …

Faculty, Staff and Student Publications

The cranial base synchondroses, comprised of opposite-facing bidirectional chondrocyte layers, drive anteroposterior cranial base growth. In humans, RUNX2 haploinsufficiency causes cleidocranial dysplasia associated with deficient midfacial growth. However, how RUNX2 regulates chondrocytes in the cranial base synchondroses remains unknown. To address this, we inactivated Runx2 in postnatal synchondrosis chondrocytes using a tamoxifen-inducible Fgfr3-creER (Fgfr3-Runx2cKO) mouse model. Fgfr3-Runx2cKO mice displayed skeletal dwarfism and reduced anteroposterior cranial base growth associated with premature synchondrosis ossification due to impaired chondrocyte proliferation, accelerated hypertrophy, apoptosis, and osteoclast-mediated cartilage resorption. Lineage tracing reveals that Runx2-deficient Fgfr3+ cells failed to differentiate into osteoblasts. Notably, Runx2-deficient chondrocytes showed …

Aortic stenosis (AS) is one of the most common types of valvular heart disease in older adults, with age being significantly associated with the development of AS. The transcatheter aortic valve replacement (TAVR) procedure, since it was first performed in 2002, has emerged as a preferred treatment option for patients who are at intermediate to high surgical risk due to advanced age or medical comorbidities. Older adults with severe AS may present with acute decompensated heart failure leading to cardiogenic shock (CS). Among patients 65 years and older with AS presenting for TAVR, 4.1% were reportedly in acute CS. Regardless …

The role of intravenous thrombolysis (IVT) in combination with endovascular thrombectomy (EVT) for the treatment of large vessel occlusion acute ischemic stroke has been evaluated exclusively outside the US, in randomized clinical trials which failed to demonstrate non-inferiority of skipping IVT. Because practice patterns and IVT dosing differ within the US, and prior observational US-based cohorts suggested improved clinical outcomes in patients who received IVT before EVT, a US-based evaluation is needed. This is a quasi-experimental study of a large US cohort using a regression discontinuity design (RDD) that enables the estimation of causal effects when randomization is not feasible. …

C-reactive protein (CRP) reflects inflammation status and is linked to poor sleep, metabolic and cardiovascular health. Methylation (MRS) and polygenic risk scores (PRS) reflect long-term systemic inflammation, and genetically-determined CRP, respectively. To refine understanding of inflammation-linked sleep and health outcomes, we construct PRS-CRPs using GWAS summary statistics and a previously-developed MRS-CRP in the Hispanic Community Health Study/Study of Latinos. Via survey-weighted linear regression, we estimate associations between blood-, PRS-, and MRS-CRP, with multiple sleep and health outcomes (n = 2217). MRS-CRP and PRS-CRPs are associated with increasing blood-CRP level by 43% and 23% per standard deviation. MRS-CRP is associated with …

Ai Solutions To The Radiology Workforce Shortage, Andrew B Jing, Naveen Garg, Jiajie Zhang, Jeffrey J Brown

Faculty, Staff and Student Publications

The growing demand for imaging services in the U.S., driven by an aging population and the rise in chronic diseases, has contributed to a significant radiology workforce shortage. Simultaneously, supply-side constraints, including limited radiology residency positions and substantial retirements, have exacerbated this gap. These imbalances increase patient wait times, risk diagnostic delays, and contribute to radiologist burnout. Artificial intelligence (AI) offers potential solutions by addressing three primary areas: demand management, workflow efficiency, and capacity building. First, to manage demand, AI tools can leverage predictive analytics and decision-support systems to reduce unnecessary imaging and prioritize high-value imaging examinations. Next, AI can …

Control Of Alveolar Bone Development, Homeostasis, And Socket Healing By Salt-Inducible Kinases, Nicha Tokavanich, Byron Chan, Katelyn Strauss, Christian D Castro Andrade, Yuki Arai, Mizuki Nagata, Marc Foretz, Daniel J Brooks, Noriaki Ono, Wanida Ono, Marc N Wein

Faculty, Staff and Student Publications

Alveolar bone supports and anchors teeth. The parathyroid hormone-related protein (PTHrP) pathway plays a key role in alveolar bone biology. Salt-inducible kinases (SIKs) are important downstream regulators of PTH/PTHrP signaling in the appendicular skeleton, where SIK inhibition increases bone formation and trabecular bone mass. However, the function of these kinases in alveolar bone remains unknown. Here, we report a critical role for SIK2/SIK3 in alveolar bone development, homeostasis, and socket healing after tooth extraction. Inducible SIK2/SIK3 (Ubq-creERt;Sik2f/f;Sik3f/f) deletion led to dramatic alveolar bone defects without changes in tooth eruption. Ablating these kinases impairs alveolar bone formation due to disrupted osteoblast …

Thsd1 Is A Multifaceted Regulator In Health And Disease, Mengjun Dai, Kuizhi Qu, Sophie Liu, Zhen Xu, Yan-Ning Rui

Faculty, Staff and Student Publications

Thrombospondin Type 1 Domain-Containing Protein 1 (THSD1) is a transmembrane protein increasingly recognized for its critical roles in vascular biology and disease pathogenesis. Initially identified as a marker of hematopoietic stem and endothelial cells during embryogenesis, THSD1 has since been implicated in a wide spectrum of physiological and pathological processes. This paper consolidates current knowledge on THSD1, with a focus on its roles in vascular integrity, perinatal disorders, and tumorigenesis. In vascular systems, THSD1 promotes focal adhesion assembly and suppresses autophagy-mediated adhesion turnover, thereby stabilizing endothelial attachment and maintaining barrier function. Genetic and functional studies support its protective role against …

Faculty, Staff and Student Publications

Background: Black and Hispanic women in the United States continue to bear disproportionate incidence of HIV related to sexual transmission and injection drug use. Specifically, women with substance use disorders (SUDs) are more likely to engage in vaginal or anal condomless sex associated with HIV transmission. Pre-exposure prophylaxis (PrEP) is a highly effective HIV prevention tool but is not widely used by racial or ethnic minority women. Effective interventions for engaging women with SUDs in HIV prevention interventions that are culturally appropriate and, therefore, more appealing to racial or ethnic minority women with SUDs are critically needed.

Using A Novel, Multi-Method Approach To Evaluate The Quality Of Self-Report Survey Data In Organizational Readiness Research, Derek W Craig, Jocelyn Hunyadi, Timothy J Walker, Lauren Workman, Maria Mcclam, Andrea Lamont, Joe R Padilla, Pamela Diamond, Abraham Wandersman, Maria E Fernandez

Faculty, Staff and Student Publications

Background: Self-report measures are essential in implementation science since many phenomena are difficult to assess directly. Nevertheless, cognitively demanding surveys increase the prevalence of careless and inattentive responses. Assessing response quality is critical to improving data validity, yet recommendations for determining response quality vary. To address this, we aimed to 1) apply a multi-method approach to assess the quality of self-report survey data in a study aimed to validate a measure of organizational readiness, 2) compare readiness scores among responses categorized as high- and low-quality, and 3) examine individual characteristics associated with low-quality responses.

Methods: We surveyed federally qualified health …

Background: The prolonged viral shedding from the gastrointestinal tract is well documented for numerous pathogens, including SARS-CoV-2. However, the impact of prolonged viral shedding on epidemiological inferences using wastewater data is not yet fully understood.

Methods: To gain a better understanding of this phenomenon at the population level, we extended a wastewater-based modeling framework that integrates viral shedding dynamics, viral load data in wastewater, case report data, and an epidemic model.

Results: Our results indicate that as an outbreak progresses, the viral load from recovered individuals gradually becomes predominant, surpassing that from the infectious population. This phenomenon leads to a …

A Multi-Level Gene-Diet Interaction Analysis Of Fish Oil And 14 Polyunsaturated Fatty Acid Traits Identifies The Fads And Gpr12 Loci, Susan Adanna Ihejirika, Alexandra Huong Chiang, Aryaman Singh, Eunice Stephen, Han Chen, Kaixiong Ye

Faculty, Staff and Student Publications

Fish oil supplements (FOS) are known to alter circulating levels of polyunsaturated fatty acids (PUFAs) but in a heterogeneous manner across individuals. These varied responses may result from unidentified gene-FOS interactions. To identify genetic factors that interact with FOS to alter the circulating levels of PUFAs, we performed a multi-level genome-wide interaction study (GWIS) of FOS on 14 plasma measurements in 200,060 unrelated European-ancestry individuals from the UK Biobank. From our single-variant tests, we identified genome-wide significant interacting SNPs (p < 5 × 10-8) in the FADS1-FADS2 gene cluster for total omega-3, omega-3%, docosapentaenoic acid (DHA), DHA%, and the omega-6 to omega-3 ratio. Among the interaction signals for omega-3%, the lead SNP, rs35473591 (C>CT, CT allele frequency = 0.34), had a lower association effect size in the FOS-taking group (β = 0.35 for …

One of the most common sites of cancer metastasis is to the bone. Bone metastasis is associated with substantial morbidity and mortality, and current therapeutic interventions remain largely palliative. Metastasizing tumor cells need to reprogram their metabolic states to adapt to the nutrient environment of distant organs; however, the role and translational relevance of lipid metabolism in bone metastasis remain unclear. Here, we used an in vivo CRISPR activation screening system coupled with positive selection to identify acyl-coenzyme A (CoA) binding protein (ACBP) as a bone metastasis driver. In nonmetastatic and weakly metastatic cancer cells, overexpression of wild-type ACBP, but …

Bone metastasis is a major cause of cancer death; however, the epigenetic determinants driving this process remain elusive. Here, we report that histone methyltransferase ASH1L is genetically amplified and is required for bone metastasis in men with prostate cancer. ASH1L rewires histone methylations and cooperates with HIF-1α to induce pro-metastatic transcriptome in invading cancer cells, resulting in monocyte differentiation into lipid-associated macrophage (LA-TAM) and enhancing their pro-tumoral phenotype in the metastatic bone niche. We identified IGF-2 as a direct target of ASH1L/HIF-1α and mediates LA-TAMs' differentiation and phenotypic changes by reprogramming oxidative phosphorylation. Pharmacologic inhibition of the ASH1L-HIF-1α-macrophages axis elicits …

Faculty, Staff and Student Publications

Background: Genetic ancestry is an important factor to account for in DNA methylation studies because genetic variation influences DNA methylation patterns. One approach uses principal components (PCs) calculated from CpG sites that overlap with common SNPs to adjust for ancestry when genotyping data is not available. However, this method does not remove technical and biological variations, such as sex and age, prior to calculating the PCs. The first PC is therefore often associated with factors other than ancestry.

Methods: We developed and adapted the adapted EpiAnceR + approach, which includes 1) residualizing the CpG data overlapping with common SNPs for …
