Addressing Patient Heterogeneity In Disease Predictive Model Development, Xu Gao, Weining Shen, Jing Ning, Ziding Feng, Jianhua Hu

Faculty, Staff and Student Publications

This paper addresses patient heterogeneity associated with prediction problems in biomedical applications. We propose a systematic hypothesis testing approach to determine the existence of patient subgroup structure and the number of subgroups in patient population if subgroups exist. A mixture of generalized linear models is considered to model the relationship between the disease outcome and patient characteristics and clinical factors, including targeted biomarker profiles. We construct a test statistic based on expectation maximization (EM) algorithm and derive its asymptotic distribution under the null hypothesis. An important computational advantage of the test is that the involved parameter estimates under the complex …

Background: Identification of circulating tumor DNA (ctDNA) following curative intent therapies is a surrogate for microscopic residual disease for patients with metastatic colorectal cancer (mCRC). Preclinically, in micrometastatic microsatellite stable (MSS) CRC, increased TGF-β signaling results in exclusion of anti-tumor cytotoxic T cells from the tumor microenvironment. Bintrafusp alfa (BA) is a bifunctional fusion protein composed of the extracellular domain of the TGF-βRII receptor ("TGF-β trap") and anti-PD-L1 antibody.

Methods: Patients with liver-limited, MSS mCRC and with detected ctDNA after complete resection of all known tumors and standard-of-care therapy were treated with 1200 mg of BA intravenously every 14 days …

Membrane-Anchored And Tumor-Targeted Il12 (Attil12)-Pbmc Therapy For Osteosarcoma, Qing Yang, Jiemiao Hu, Zhiliang Jia, Qi Wang, Jing Wang, Long Hoang Dao, Wendong Zhang, Sheng Zhang, Xueqing Xia, Richard Gorlick, Shulin Li

Faculty, Staff and Student Publications

Purpose: Chimeric antigen receptor (CAR) T-cell therapy has shown great promise for treating hematologic malignancies but requires a long duration of T-cell expansion, is associated with severe toxicity, and has limited efficacy for treating solid tumors. We designed experiments to address those challenges.

Experimental design: We generated a cell membrane-anchored and tumor-targeted IL12 (attIL12) to arm peripheral blood mononuclear cells (PBMC) instead of T cells to omit the expansion phase for required CAR T cells.

Results: This IL12-based attIL12-PBMC therapy showed significant antitumor efficacy in both heterogeneous osteosarcoma patient-derived xenograft tumors and metastatic osteosarcoma tumors with no observable toxic effects. …

Estrogen-Related Receptor Alpha Is An Ampk-Regulated Factor That Promotes Ischemic Muscle Revascularization And Recovery In Diet-Induced Obese Mice, Danesh H Sopariwala, Andrea S Rios, Mi Kyung Park, Min Sup Song, Ashok Kumar, Vihang A Narkar

Faculty, Staff and Student Publications

Obesity and type II diabetes are leading causes of peripheral arterial disease (PAD), which is characterized by vascular insufficiency and ischemic damage in the limb skeletal muscle. Glycemic control is not sufficient to prevent progression of PAD, and molecular targets that can promote muscle neo-angiogenesis in obesity and diabetes remain poorly defined. Here, we have investigated whether nuclear receptor estrogen-related receptor alpha (ERRα) can promote ischemic revascularization in the skeletal muscles of diet-induced obese (DIO) mice. Using muscle-specific ERRα transgenic mice, we found that ERRα overexpression promotes revascularization, marked by increased capillary staining and muscle perfusion in DIO mice after …

Repeatability And Reproducibility Assessment Of The Apparent Diffusion Coefficient In The Prostate: A Trial Of The Ecog-Acrin Research Group (Acrin 6701), Michael A Boss, Bradley S Snyder, Eunhee Kim, Dena Flamini, Sarah Englander, Karthik M Sundaram, Naveen Gumpeni, Suzanne L Palmer, Haesun Choi, Adam T Froemming, Thorsten Persigehl, Matthew S Davenport, Dariya Malyarenko, Thomas L Chenevert, Mark A Rosen

Faculty, Staff and Student Publications

Background: Uncertainty regarding the reproducibility of the apparent diffusion coefficient (ADC) hampers the use of quantitative diffusion-weighted imaging (DWI) in evaluation of the prostate with magnetic resonance imaging MRI. The quantitative imaging biomarkers alliance (QIBA) profile for quantitative DWI claims a within-subject coefficient of variation (wCV) for prostate lesion ADC of 0.17. Improved understanding of ADC reproducibility would aid the use of quantitative diffusion in prostate MRI evaluation.

Purpose: Evaluation of the repeatability (same-day) and reproducibility (multi-day) of whole-prostate and focal-lesion ADC assessment in a multi-site setting.

Study type: Prospective multi-institutional.

Subjects: Twenty-nine males, ages 53 to 80 (median 63) …

Intermediary Role Of Lung Alveolar Type 1 Cells In Epithelial Repair Upon Sendai Virus Infection, Belinda J Hernandez, Margo P Cain, Anne M Lynch, Jose R Flores, Michael J Tuvim, Burton F Dickey, Jichao Chen

Faculty, Staff and Student Publications

The lung epithelium forms the first barrier against respiratory pathogens and noxious chemicals; however, little is known about how more than 90% of this barrier, made of AT1 (alveolar type 1) cells, responds to injury. Using the Sendai virus to model natural infection in mice, we find evidence that AT1 cells have an intermediary role by persisting in areas depleted of AT2 cells, upregulating IFN responsive genes, and receding from invading airway cells. Sendai virus infection mobilizes airway cells to form alveolar SOX2+ (Sry-box 2+) clusters without differentiating into AT1 or AT2 cells. Large AT2 cell-depleted areas remain covered by …

Invasive alien species (IAS) rank among the most significant drivers of species extinction and ecosystem degradation resulting in significant impacts on socio-economic development. The recent exponential spread of IAS in most of Africa is attributed to poor border biosecurity due to porous borders that have failed to prevent initial introductions. In addition, countries lack adequate information about potential invasions and have limited capacity to reduce the risk of invasions. Horizon scanning is an approach that prioritises the risks of potential IAS through rapid assessments. A group of 28 subject matter experts used an adapted methodology to assess 1700 potential IAS …

Loma Linda University Electronic Theses, Dissertations & Projects

We reviewed the literature on mindfulness and its effects on psychological functioning. EEG studies have shown that different approaches to meditation, including MBSR, guided imagery, etc. have been associated with better interoception, increases in left frontal activity, and better stress regulation. These findings were used to create a study protocol that utilizes a somatically based intervention, the Community Resiliency Model (CRM) to decrease test taking anxiety in graduate school students.

Force Comparison Of Rotational Tooth Movements For Loop-Design And Traditional Aligners, Robert Olsen

Loma Linda University Electronic Theses, Dissertations & Projects

Introduction

This study aimed to evaluate the force (F) and torque (Tq) exerted on a rotated canine and molar tooth by two different aligner systems. An ArchForm loop clear aligner (AFL) was compared to a traditional clear aligner (T) with the force (F) and torque (Tq) compared. A reduction in F and Tq with AFL aligners could possibly decrease the incidence of Orthodontic Root Resorption (ORR), while also creating more effective forces for tooth movement.

Materials and Methods

Two types of T aligners varying by material thickness were compared to two types of AFL aligners varying by loop width. All …

Summaries Of Arkansas Cotton Research 2021, Fred Bourland

Arkansas Agricultural Experiment Station Research Series

While the basic growth and development of the cotton plant have not changed significantly in recent history, the business of cotton production is ever-changing. The last two years have seen us plant a crop just about as late as we thought possible, yet extended favorable conditions at season's end have been our salvation, helping to lead us to record yields. The economic environment over the last few years has been such that farmers need to produce record or near-record yields to advance. Unfortunately, production levels at the state yield average barely cover out-of-pocket expenses.

Great uncertainties exist for the upcoming …

Analysis Of Graph Layout Algorithms For Use In Command And Control Network Graphs, Matthew R. Stone

Theses and Dissertations

This research is intended to determine which styles of layout algorithm are well suited to Command and Control (C2) network graphs to replace current manual layout methods. Manual methods are time intensive and an automated layout algorithm should decrease the time spent creating network graphs. Simulations on realistic synthetically generated graphs provide information to help infer which algorithms perform better than others on this problem. Data is generated using statistics drawn from multiple real world C2 network graphs. The three algorithms tested against this data are the Spectral algorithm, the Dot algorithm, and the Fruchterman-Reingold algorithm. The results include a …

Electroconvulsive therapy (ECT) is a highly therapeutic and cost-effective treatment for severe and/or treatment-resistant major depression. However, because of the varied clinical practices, there is a great deal of heterogeneity in how ECT is delivered and documented. This represents both an opportunity to study how differences in implementation influence clinical outcomes and a challenge for carrying out coordinated quality improvement and research efforts across multiple ECT centers. The National Network of Depression Centers, a consortium of 26+ US academic medical centers of excellence providing care for patients with mood disorders, formed a task group with the goals of promoting best …

Revisiting Sex Differences In The Acquisition And Extinction Of Threat Conditioning In Humans, Zhenfu Wen, Jamie Fried, Edward F Pace-Schott, Sara W Lazar, Mohammed R Milad

Faculty, Staff and Student Publications

Findings pertaining to sex differences in the acquisition and extinction of threat conditioning, a paradigm widely used to study emotional homeostasis, remain inconsistent, particularly in humans. This inconsistency is likely due to multiple factors, one of which is sample size. Here, we pooled functional magnetic resonance imaging (fMRI) and skin conductance response (SCR) data from multiple studies in healthy humans to examine sex differences during threat conditioning, extinction learning, and extinction memory recall. We observed increased functional activation in males, relative to females, in multiple parietal and frontal (medial and lateral) cortical regions during acquisition of threat conditioning and extinction …

A New Pathogenic Polg Variant, S Nicholas Russo, Ekta G Shah, William C Copeland, Mary Kay Koenig

Faculty, Staff and Student Publications

POLG gene mutations are the most common causes of inherited mitochondrial disorders. The enzyme produced by this gene is responsible for the replication and repair of mitochondrial DNA. To date, around 300 pathogenic variants have been described in this gene. The resulting clinical outcomes of POLG mutations are widely variable in both phenotype and severity. There is considerable overlap in the phenotype of the so-called POLG syndromes with no clear genotype-phenotype correlation. Here we describe a newly discovered pathogenic variant in the POLG gene in a 7-year-old male that died of uncontrollable refractory status epilepticus. Genetic epilepsy panel sequencing identified …
