Exploring The Link Between Urinary Albumin Excretion And Neutrophil-To-Lymphocyte Ratio In Type 2 Diabetes Mellitus: A Cross-Sectional Study, B Dharani, S Sugantha Priya, Suba A

Digital Journal of Clinical Medicine

Objectives: Type 2 diabetes mellitus (T2DM) is a chronic disease characterized by persistent hyperglycemia resulting from insulin resistance and inadequate insulin production. A critical aspect of T2DM is its microvascular complications, notably diabetic nephropathy, which progresses from microalbuminuria to overt proteinuria, and eventually End-Stage Renal Disease (ESRD). Inflammation-induced endothelial dysfunction is a key factor in the progression of diabetic nephropathy. The neutrophil-to-lymphocyte ratio (NLR) is an easily measurable marker derived from routine leukocyte analysis, reflecting systemic inflammation. Despite the known association between chronic inflammation and diabetic nephropathy, studies exploring this relationship remain limited. This study aims to investigate the correlation …

The role of Epstein-Barr virus (EBV) in lymphoma cells of nodular sclerosis classic Hodgkin lymphoma (NScHL) is controversial. Our aim was to explore this and establish a clinically feasible model for risk stratification. We interrogated data from 542 consecutive subjects with NScHL receiving ABVD therapy and demonstrated EBV-infection in their lymphoma cells with EBV-encoded small RNAs (EBERs) in situ hybridization. Subjects were divided into training and validation datasets. As data from the training dataset suggested EBERs-positivity was the only independent prognostic factor for both progression-free survival (PFS) and overall survival (OS), we developed corresponding prognostic models based on it. Our …

Designing Clinical Trials For Patients Who Are Not Average, Thomas E Yankeelov, David A Hormuth, Ernesto A B F Lima, Guillermo Lorenzo, Chengyue Wu, Lois C Okereke, Gaiane M Rauch, Aradhana M Venkatesan, Caroline Chung

Faculty, Staff and Student Publications

The heterogeneity inherent in cancer means that even a successful clinical trial merely results in a therapeutic regimen that achieves, on average, a positive result only in a subset of patients. The only way to optimize an intervention for an individual patient is to reframe their treatment as their own, personalized trial. Toward this goal, we formulate a computational framework for performing personalized trials that rely on four mathematical techniques. First, mathematical models that can be calibrated with patient-specific data to make accurate predictions of response. Second, digital twins built on these models capable of simulating the effects of interventions. …

Results: 217 patients were included. 47% (n …

Dietary Folate And Cofactors Accelerate Age-Dependent P16 Epimutation To Promote Intestinal Tumorigenesis, Li Yang, Robert C Peery, Leah M Farmer, Xia Gao, Yiqun Zhang, Chad J Creighton, Lanjing Zhang, Lanlan Shen

Faculty, Staff and Students Publications

The extent to which non-genetic environmental factors, such as diet, contribute to carcinogenesis has been long debated. One potential mechanism for the effects of environmental factors is through epigenetic modifications that affect gene expression without changing the underlying DNA sequence. However, the functional cooperation between dietary factors and cancer-causing epigenetic regulation is largely unknown. Here, we use a mouse model of age-dependent p16 epimutation, in which the p16 gene activity is directly controlled by promoter DNA methylation. We show p16 epimutation is modulated by folate and cofactors in dietary supplementation, which leads to increased colon cancer risk. Importantly, our findings …

Organelle Proteomic Profiling Reveals Lysosomal Heterogeneity In Association With Longevity, Yong Yu, Shihong M Gao, Youchen Guan, Pei-Wen Hu, Qinghao Zhang, Jiaming Liu, Bentian Jing, Qian Zhao, David M Sabatini, Monther Abu-Remaileh, Sung Yun Jung, Meng C Wang

Faculty, Staff and Students Publications

Lysosomes are active sites to integrate cellular metabolism and signal transduction. A collection of proteins associated with the lysosome mediate these metabolic and signaling functions. Both lysosomal metabolism and lysosomal signaling have been linked to longevity regulation; however, how lysosomes adjust their protein composition to accommodate this regulation remains unclear. Using deep proteomic profiling, we systemically profiled lysosome-associated proteins linked with four different longevity mechanisms. We discovered the lysosomal recruitment of AMP-activated protein kinase and nucleoporin proteins and their requirements for longevity in response to increased lysosomal lipolysis. Through comparative proteomic analyses of lysosomes from different tissues and labeled with …

Cerebrospinal fluid (CSF) analysis is underutilized in patients with glioblastoma (GBM), partly due to a lack of studies demonstrating the clinical utility of CSF biomarkers. While some studies show the utility of CSF cell-free DNA analysis, studies analyzing CSF metabolites in patients with glioblastoma are limited. Diffuse gliomas have altered cellular metabolism. For example, mutations in isocitrate dehydrogenase enzymes (e.g., IDH1 and IDH2) are common in diffuse gliomas and lead to increased levels of D-2-hydroxyglutarate in CSF. However, there is a poor understanding of changes CSF metabolites in GBM patients. In this study, we performed targeted metabolomic analysis of CSF …

Live Calcium Imaging Of Virus-Infected Human Intestinal Organoid Monolayers Using Genetically Encoded Calcium Indicators, J Thomas Gebert, Francesca J Scribano, Kristen A Engevik, Joseph M Hyser

Faculty, Staff and Students Publications

Calcium signaling is an integral regulator of nearly every tissue. Within the intestinal epithelium, calcium is involved in the regulation of secretory activity, actin dynamics, inflammatory responses, stem cell proliferation, and many other uncharacterized cellular functions. As such, mapping calcium signaling dynamics within the intestinal epithelium can provide insight into homeostatic cellular processes and unveil unique responses to various stimuli. Human intestinal organoids (HIOs) are a high-throughput, human-derived model to study the intestinal epithelium and thus represent a useful system to investigate calcium dynamics. This paper describes a protocol to stably transduce HIOs with genetically encoded calcium indicators (GECIs), perform …

Advancements In Revascularization Strategies For Acute Mesenteric Ischemia: A Comprehensive Review, Jacob J Gries, Hafeez Ul Hassan Virk, Bing Chen, Takashi Sakamoto, Mahboob Alam, Chayakrit Krittanawong

Faculty, Staff and Students Publications

Even with modern advancements in the management of acute mesenteric ischemia over the past decade, morbidity and mortality remain high, and the best primary treatment modality is still debated amongst interventionalists. Traditionally, interventionalists have favored an open surgical approach but are now trending for endovascular interventions due to apparent reduced mortality and complications. Newer studies suggest hybrid approaches, and intestinal stroke centers may be superior to either strategy alone. This narrative review will explore the natural history of acute mesenteric ischemia with the aim of increasing interventionalist awareness of modern advancements in revascularization strategies for this devastating disease.

Deepvelo: Deep Learning Extends Rna Velocity To Multi-Lineage Systems With Cell-Specific Kinetics, Haotian Cui, Hassaan Maan, Maria C Vladoiu, Jiao Zhang, Michael D Taylor, Bo Wang

Faculty, Staff and Students Publications

Existing RNA velocity estimation methods strongly rely on predefined dynamics and cell-agnostic constant transcriptional kinetic rates, assumptions often violated in complex and heterogeneous single-cell RNA sequencing (scRNA-seq) data. Using a graph convolution network, DeepVelo overcomes these limitations by generalizing RNA velocity to cell populations containing time-dependent kinetics and multiple lineages. DeepVelo infers time-varying cellular rates of transcription, splicing, and degradation, recovers each cell's stage in the differentiation process, and detects functionally relevant driver genes regulating these processes. Application to various developmental and pathogenic processes demonstrates DeepVelo's capacity to study complex differentiation and lineage decision events in heterogeneous scRNA-seq data.

Polygenic Scores For Tobacco Use Provide Insights Into Systemic Health Risks In A Diverse Ehr-Linked Biobank In Los Angeles, Vidhya Venkateswaran, Kristin Boulier, Yi Ding, Ruth Johnson, Arjun Bhattacharya, Bogdan Pasaniuc

Faculty, Staff and Student Publications

Tobacco use is a major risk factor for many diseases and is heavily influenced by environmental factors with significant underlying genetic contributions. Here, we evaluated the predictive performance, risk stratification, and potential systemic health effects of tobacco use disorder (TUD) predisposing germline variants using a European- ancestry-derived polygenic score (PGS) in 24,202 participants from the multi-ancestry, hospital-based UCLA ATLAS biobank. Among genetically inferred ancestry groups (GIAs), TUD-PGS was significantly associated with TUD in European American (EA) (OR: 1.20, CI: [1.16, 1.24]), Hispanic/Latin American (HL) (OR:1.19, CI: [1.11, 1.28]), and East Asian American (EAA) (OR: 1.18, CI: [1.06, 1.31]) GIAs but …

In a 3-arm presurgical trial, four-six weeks exemestane 25 mg three times/week (TIW) was non-inferior to 25 mg/day (QD) in suppressing circulating estradiol in postmenopausal women with ER-positive breast cancer. Since obesity may decrease exemestane efficacy, we analyzed changes in sex steroids, adipokines, Ki-67, and drug levels in relation to obesity. Postmenopausal women with early-stage ER-positive breast cancer were randomized to either exemestane 25 mg QD (n = 57), 25 mg TIW (n = 57), or 25 mg/week (QW, n = 62) for 4-6 weeks before breast surgery. Serum and tissue pre- and post-treatment biomarkers were stratified by body mass …

Predicting Radiotherapy Patient Outcomes With Real-Time Clinical Data Using Mathematical Modelling, Alexander P Browning, Thomas D Lewin, Ruth E Baker, Philip K Maini, Eduardo G Moros, Jimmy Caudell, Helen M Byrne, Heiko Enderling

Faculty, Staff and Student Publications

Longitudinal tumour volume data from head-and-neck cancer patients show that tumours of comparable pre-treatment size and stage may respond very differently to the same radiotherapy fractionation protocol. Mathematical models are often proposed to predict treatment outcome in this context, and have the potential to guide clinical decision-making and inform personalised fractionation protocols. Hindering effective use of models in this context is the sparsity of clinical measurements juxtaposed with the model complexity required to produce the full range of possible patient responses. In this work, we present a compartment model of tumour volume and tumour composition, which, despite relative simplicity, is …

Mild traumatic brain injury (mTBI) is a public health concern. The present study aimed to develop an automatic classifier to distinguish between patients with chronic mTBI (n = 83) and healthy controls (HCs) (n = 40). Resting-state functional MRI (rs-fMRI) and positron emission tomography (PET) imaging were acquired from the subjects. We proposed a novel deep-learning-based framework, including an autoencoder (AE), to extract high-level latent and rectified linear unit (ReLU) and sigmoid activation functions. Single and multimodality algorithms integrating multiple rs-fMRI metrics and PET data were developed. We hypothesized that combining different imaging modalities provides complementary information and …

Obesity And Skeletal Fragility, Rui Chen, Reina Armamento-Villareal

Faculty, Staff and Students Publications

Skeletal fracture has recently emerged as a complication of obesity. Given the normal or better than normal bone mineral density (BMD), the skeletal fragility of these patients appears to be a problem of bone quality rather than quantity. Type 2 diabetes mellitus (T2DM), the incidence of which increases with increasing body mass index, is also associated with an increased risk for fractures despite a normal or high BMD. With the additional bone pathology from diabetes itself, patients with both obesity and T2DM could have a worse skeletal profile. Clinically, however, there are no available methods for identifying those who are …

Epilepsy is a prevalent disorder involving neuronal network hyperexcitability, yet existing therapeutic strategies often fail to provide optimal patient outcomes. Chemogenetic approaches, where exogenous receptors are expressed in defined brain areas and specifically activated by selective agonists, are appealing methods to constrain overactive neuronal activity. We developed BARNI (Bradanicline- and Acetylcholine-activated Receptor for Neuronal Inhibition), an engineered channel comprised of the α7 nicotinic acetylcholine receptor ligand-binding domain coupled to an α1 glycine receptor anion pore domain. Here we demonstrate that BARNI activation by the clinical stage α7 nicotinic acetylcholine receptor-selective agonist bradanicline effectively suppressed targeted neuronal activity, and controlled both …

Shortened telomere lengths (TLs) can be caused by single nucleotide polymorphisms and loss-of-function mutations in telomere-related genes (TRG), as well as ageing and lifestyle factors such as smoking. Our objective was to determine if shortened TL is associated with interstitial lung disease (ILD) in individuals with rheumatoid arthritis (RA). This is the largest study to demonstrate and replicate that shortened peripheral blood leukocytes-TL is associated with ILD in patients with RA compared with RA without ILD in a multinational cohort, and short PBL-TL was associated with baseline disease severity in RA-ILD as measured by forced vital capacity percent predicted.

Avaren-Fc, A Novel Immunotherapeutic, Recruits Nk Cells In B16f10 Melanoma Tumor Tissue, Sreevatsa Vemuri, Katarina Mayer, Nobuyuki Matoba

Posters-at-the-Capitol

Melanoma is the fifth most common cancer in the US, with limited effective immunotherapeutic options available for patients. Avaren-Fc (AvFc) is a novel experimental immunotherapeutic agent with a unique “lectibody” property. It is capable of targeting cancer cells through the selective recognition of high mannose glycans, which are aberrantly overrepresented on the surface of malignant cells. AvFc can interact with circulating effector immune cells equipped with Fc receptors, such as natural killer (NK) cells to induce antibody-dependent cell-mediated cytotoxicity (ADCC) and kill cancer cells. Previous work has shown that AvFc effectively induces ADCC activity against B16F10 cancer cells in vitro …

Managing Diffuse Alveolar Hemorrhage In A Critical Care Setting, Yong-Chan Kim, Jessica Marcela Daza, Juan C. Naranjo, Timothy Heath

Research Symposium

Background: Diffuse alveolar hemorrhage (DAH) is defined as disruption of the alveolar-capillary basement membrane, causing bleeding into the alveolar spaces. It is one of the rarest complications in systemic lupus erythematosus (SLE) and life-threatening conditions. Symptoms include shortness of breath, cough, fluctuating fever, and rarely hemoptysis. Complications include acute respiratory distress syndrome. The test of choice for diagnosis is bronchoalveolar lavage (BAL). The hallmark is that BAL aliquots are progressively more hemorrhagic. CT-chest shows ground glass or consolidative opacities that are usually diffuse and bilateral nonspecific. There is no cornerstone therapy for DAH due to SLE. Considering this a fatal …

Endophthalmitis In An Elderly Patient - A Case Of Delayed Transfer And Successful Management, Vamsikalayan Borra, Roy Kondapavuluru, Sreejith Pillali, Sabhi Gull, Andres Suarez Parraga
