Faculty, Staff and Student Publications

Here we develop two new social indices: The ADA PARC Absolute Economic Opportunity Index and the ADA PARC Relative Economic Opportunity Index. These indices allow us novel examinations of economic equity between people with and without disabilities within a U.S. State and between people with disabilities in different states using aggregations of multiple component economic indicators. These represent the first efforts to offer U.S. indices of this focus, an important development given the distinct economic needs of people with disabilities and the value in accounting for distinct national policies. The indices rely on U.S. Census and other data on economic …

Ensuring Trust In Genomics Research, Erman Ayday, Jaideep Vaidya, Xiaoqian Jiang, Amalio Telenti

Faculty, Staff and Student Publications

Reproducibility, transparency, representation, and privacy underpin the trust on genomics research in general and genome-wide association studies (GWAS) in particular. Concerns about these issues can be mitigated by technologies that address privacy protection, quality control, and verifiability of GWAS. However, many of the existing technological solutions have been developed in isolation and may address one aspect of reproducibility, transparency, representation, and privacy of GWAS while unknowingly impacting other aspects. As a consequence, the current patchwork of technological tools only partially and in an overlapping manner address issues with GWAS, sometimes even creating more problems. This paper addresses the progress in …

Exercise is a non-pharmacologic intervention to reduce cancer risk, though its impact on patients with LS has not been prospectively studied. Here, we evaluated the impact of a 12-month aerobic exercise cycling intervention in the biology of the immune system in LS carriers.

PATIENTS AND METHODS: To address this, we enrolled 21 patients with LS onto a non-randomized, sequential intervention assignation, clinical trial to assess the effect of a 12-month exercise program that included cycling classes 3 times weekly for 45 minutes …

Nanobomb Optical Coherence Elastography In Multilayered Phantoms, Maryam Hatami, Dmitry Nevozhay, Manmohan Singh, Alexander Schill, Paul Boerner, Salavat Aglyamov, Konstantin Sokolov, Kirill V Larin

Faculty, Staff and Student Publications

Many tissues are composed of layered structures, and a better understanding of the changes in the layered tissue biomechanics can enable advanced guidance and monitoring of therapy. The advent of elastography using longitudinally propagating shear waves (LSWs) has created the prospect of a high-resolution assessment of depth-dependent tissue elasticity. Laser activation of liquid-to-gas phase transition of dye-loaded perfluorocarbon (PFC) nanodroplets (a.k.a., nanobombs) can produce highly localized LSWs. This study aims to leverage the potential of photoactivation of nanobombs to incudce LSWs with very high-frequency content in wave-based optical coherence elastography (OCE) to estimate the elasticity gradient with high resolution. In …

Aim: In response to the coronavirus 2019 disease (COVID-19) pandemic, governments worldwide implemented measures to prevent infection, resulting in restricted school activities, restricted children’s freedom of movement, and increased risk of violence and injuries at home, including traumatic brain injury (TBI), among children. In Brazil, the consequences of the COVID-19 pandemic on the causes, severity, and mortality of pediatric TBI have not yet been investigated. Thus, our study aimed to determine whether the COVID-19 pandemic has affected the epidemiology of pediatric TBI among Brazilian children.

Materials and methods: We investigated the patients with TBI aged <18 years who visited a tertiary trauma center in Brazil in 2019 and 2020. TBI-related variables, such as classification, mechanism, clinical manifestations, need for intervention, morbidity, and mortality, were recorded. Furthermore, we used a nationwide databank to collect information on mortality from external causes of trauma and violence in the pediatric population in 2019 and 2020. The Mann-Whitney test was used to compare quantitative variables related to the mechanisms and severity of TBI in both periods in order to determine the impact of the COVID-19 pandemic.

Results: Of the patients with …

Factors Impacting Adoption Of And Experience With Point-Of-Use Activated Carbon Faucet Mount Water Filters, Aubrey Gilliland, Victoria Peluso, Corisandra Leyton-High, Susanne Straif-Bourgeois, Kari Brisolara, Greg Pierce, Kelsey Pieper, Adrienne Katner

Journal of the Louisiana Public Health Association

Introduction: Public health officials increasingly rely on point-of-use drinking water filters (POUs) to reduce waterborne lead exposures, and upcoming regulatory changes will soon require utilities to distribute POUs under certain conditions. While POUs are generally a costeffective measure for reducing lead exposure, they may not be adoptable by all households. To promote sustained adoption of POUs, we need to understand the situational and technical factors which may facilitate or impede adoption. Methods: Study participants were interviewed before and after field-testing of activated carbon faucet mount POU filters to identify factors impacting adoption in New Orleans and Enterprise, Louisiana, both sites …

Gene Variants In Bola-Dmb, Decr1, Fasn And Srebf1 Associated With Conceptus Death On Day 16 Of Pregnancy In Holstein Cows [Abstract], Carolina L. Gonzalez-Berrios, Courtney Bowden, Pablo J. Pinedo, Jeanette V. Bishop, Hana Van Campen, Thomas R. R. Hansen, Milton G. Thomas

United States Department of Agriculture Wildlife Services: Staff Publications

Investigating the influences of single nucleotide polymorphisms (SNP) associated with conceptus death (CD) on day 16 of pregnancy could distinguish cows who have inferior value for fertility traits. We hypothesized that CD is associated with SNP genotypes that disrupt maternal recognition and lead to early pregnancy loss. RNA sequences from Holstein cow pregnancies (n = 15) with normal conceptuses (Norm) or CD were subjected to SNP discovery via Qiagen CLC Genomics Workbench. Selected SNP were based on previous fertility studies, differentially expressed genes within pregnancy development analyses and proximity to SNP associated with fertility traits in the Cattle QTL …

Atrial Shunt Therapy For Heart Failure: An Update, William Gray

Department of Medicine Faculty Papers

Transcatheter atrial shunt therapies, designed to dynamically lower left atrial (LA) pressure by shunting blood into the larger reservoir of the right atrium and central veins, have been developed as a novel treatment for heart failure (HF) over the past 10+ years. Several atrial shunt devices and procedures are currently in development with several pivotal randomized clinical trials (RCT) underway; however, only 2 sham-controlled RCT (both with the Atrial Shunt Device [Corvia Medical] in HF with EF ≥ 40%) have been reported thus far; a mechanistic RCT (n = 44) that demonstrated a reduction in exercise LA pressure at …

Spatial Transferability Of An Agent‑Based Model To Simulate Taenia Solium Control Interventions, Francesco Pizzitutti, Gabrielle Bonnet, Eloy Gonzales-Gustavson, William K. Pan, Hector H. Garcia, Armando E. Gonzalez, Seth E. O’Neal, Sarah Gabriël, Cysticercosis Working Group Peru

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background

Models can be used to study and predict the impact of interventions aimed at controlling the spread of infectious agents, such as Taenia solium, a zoonotic parasite whose larval stage causes epilepsy and economic loss in many rural areas of the developing nations. To enhance the credibility of model estimates, calibration against observed data is necessary. However, this process may lead to a paradoxical dependence of model parameters on location-specific data, thus limiting the model’s geographic transferability.

Methods

In this study, we adopted a non-local model calibration approach to assess whether it can improve the spatial transferability of …

Acute Hepatic Porphyrias: Recommendations For Diagnosis And Management With Real-World Examples, Akshata Moghe, Amy Dickey, Angelika Erwin, Rebecca K. Leaf, Alan O'Brien, John G. Quigley, Manish Thapar, Karl E. Anderson

Division of Gastroenterology and Hepatology Faculty Papers

Acute hepatic porphyria (AHP) is a group of four rare inherited diseases, each resulting from a deficiency in a distinct enzyme in the heme biosynthetic pathway. Characterized by acute neurovisceral symptoms that may mimic other medical and psychiatric conditions, lack of recognition of the disease often leads to a delay in diagnosis and initiation of effective treatment. Biochemical testing for pathway intermediates that accumulate when the disease is active forms the basis for screening and establishing a diagnosis. Subsequent genetic analysis identifies the pathogenic variant, supporting screening of family members and genetic counseling. Management of AHP involves avoidance of known …

Recent Strategies For Cancer Therapy: Polymer Nanoparticles Carrying Medicinally Important Phytochemicals And Their Cellular Targets, Metin Yıldırım, Melike Sessevmez, Samet Poyraz, Nejat Düzgüneş

Pacific Faculty Work

Cancer is a leading cause of death in the world today. In addition to the side effects of the chemotherapeutic drugs used to treat cancer, the development of resistance to the drugs renders the existing drugs ineffective. Therefore, there is an urgent need to develop novel anticancer agents. Medicinally important phytochemicals such as curcumin, naringenin, quercetin, epigallocatechin gallate, thymoquinone, kaempferol, resveratrol, genistein, and apigenin have some drawbacks, including low solubility in water, stability and bioavailability issues, despite having significant anticancer effects. Encapsulation of these natural compounds into polymer nanoparticles (NPs) is a novel technology that could overcome these constraints. In …

Cardiac muscle has the highest mitochondrial density of any human tissue, but mitochondrial dysfunction is not a recognized cause of isolated cardiomyopathy. Here, we determined that the rare mitofusin (MFN) 2 R400Q mutation is 15-20× over-represented in clinical cardiomyopathy, whereas this specific mutation is not reported as a cause of MFN2 mutant-induced peripheral neuropathy, Charcot-Marie-Tooth disease type 2A (CMT2A). Accordingly, we interrogated the enzymatic, biophysical, and functional characteristics of MFN2 Q400 versus wild-type and CMT2A-causing MFN2 mutants. All MFN2 mutants had impaired mitochondrial fusion, the canonical MFN2 function. Compared to MFN2 T105M that lacked catalytic GTPase activity and exhibited normal …

Psychosocial Predictors Of Cosmetic Surgery Acceptance Among Young Adult Women In The Uae. The Role Of Selfie Behavior, Narcissism And Religiosity: A Cross-Sectional Study, Amna Ahmad Alsadani

Theses

Cosmetic surgery is prevalent in the UAE and has been linked to negative psychological and physical consequences. The present study investigates psychosocial factors expected to predict an acceptance of cosmetic surgery among young adult women in the UAE. It was hypothesized that high selfie behavior, high narcissism, and low levels of religiosity would have a positive association with an interest in cosmetic surgery. The factors that motivate people to undergo cosmetic surgery were assessed using the 15-item Acceptance of Cosmetic Surgery Scale. Selfie behavior was examined using two questions derived from previous research. Narcissism was assessed using the 16-item Narcissistic …

Multi-Omics Analysis Of Circulating Exosomes In Adherent Long-Term Treated Osa Patients, Abdelnaby Khalyfa, Jose M. Marin, David Sanz-Rubio, Zhen Lyu, Trupti Joshi, David Gozal

Biomedical Sciences

Obstructive sleep apnea (OSA) is a highly prevalent chronic disease affecting nearly a billion people globally and increasing the risk of multi-organ morbidity and overall mortality. However, the mechanisms underlying such adverse outcomes remain incompletely delineated. Extracellular vesicles (exosomes) are secreted by most cells, are involved in both proximal and long-distance intercellular communication, and contribute toward homeostasis under physiological conditions. A multi-omics integrative assessment of plasma-derived exosomes from adult OSA patients prior to and after 1-year adherent CPAP treatment is lacking. We conducted multi-omic integrative assessments of plasma-derived exosomes from adult OSA patients prior to and following 1-year adherent CPAP …

Unraveling The Twist: Spatial Navigational Challenges In Cervical Dystonia, Hanieh Agharazi, Alexander Wang, Aratrik Guha, Palak Gupta, Aasef G. Shaikh

Faculty Scholarship

Background: Cervical dystonia (CD) is an intricate neurological condition with motor and nonmotor symptoms. These include disruptions in visual perception, self-orientation, visual working memory, and vestibular functions. However, the specific impact of CD on perceiving self-motion direction, especially with isolated visual or vestibular stimuli, remains largely unexplored. Objective: This study aimed to examine the effects of CD on linear motion perception, hypothesizing impaired heading discrimination in both vestibular and visual tasks, and that such deficits correlate with the disease severity. Methods: We employed a cutting-edge motion platform to precisely control whole-body linear motion. Through repeated two-alternative forced-choice tasks, we assessed …
