Chronic Environmental Exposure To Metal Mixtures In Tribal Populations And Potential Immune System Effects, Jennifer J. Ong

Biomedical Sciences ETDs

Hardrock mining in the United States (US) has left a legacy of mixed metal mine waste sites. Wastes may contain multiple metals of health concern, including arsenic, cadmium, lead, mercury, and uranium, among others. Mining waste sites are disproportionately located on or contiguous to the watersheds of tribal lands. Due to proximity, and because of reliance on natural resources to maintain traditional diets and customs, Native American communities’ contact with multiple metals is often increased. Two impacted communities are the Cheyenne River Sioux Tribe (CRST) and Navajo Nation. Both tribes have expressed concerns that metals in mine waste adversely affect …

Modeling Mastitis Reveals Relative Impact Of (A)Symptomatic Infectivity, O. Liota Weinbaum, Helen J. Wearing

Shared Knowledge Conference

Despite widespread compliance with control recommendations, chronic infectious disease remains problematic in animal agriculture. Efforts to disrupt transmission target symptomatic individuals, but disease persists at the population level. Staphylococcus aureus mastitis in dairy cows is a painful inflammation of the udder that reduces milk volume and quality. The popularly targeted transmission mechanism is contact between the milk of symptomatic cows and the udders of susceptible cows via milking equipment. A common control practice is to milk symptomatic cows last, known as the Milk Last Intervention (MLI). However, asymptomatic cows are also infectious. We suspect that they play an important role …

The Role Of Adaptive Immunity In Chronic Hypoxia-Induced Pulmonary Hypertension, Levi David Maston

Biomedical Sciences ETDs

Inflammation is a prominent pathologic feature in pulmonary arterial hypertension as demonstrated by pulmonary vascular infiltration of inflammatory cells, including T and B lymphocytes. However, the contribution of the adaptive immune system is not well characterized in pulmonary hypertension (PH) caused by chronic hypoxia (CH). Inflammatory cells, through various mechanisms, have the capability to increase pulmonary vascular resistance in various disease states. CD4⁺T cells have the potential to play a significant role in the disease process initiated by hypoxia. CD4⁺T cells are largely responsible for orchestrating downstream immune processes and are critical in focusing and amplifying …

Integrating Treatment For Co-Occurring Mental Health Conditions, Amy M Yule, John F Kelly

Project ECHO Bibliography

Given the high co-occurrence between alcohol use disorder (AUD) and mental health conditions (MHCs), and the increased morbidity associated with the presence of co-occurring disorders, it is important that co-occurring disorders be identified and both disorders addressed in integrated treatment. Tremendous heterogeneity exists among individuals with co-occurring conditions, and factors related to both AUD and MHCs, including symptom type and acuity, illness severity, the chronicity of symptoms, and recovery capital, should be considered when recommending treatment interventions. This article reviews the prevalence of co-occurring AUD and MHCs, screening tools to identify individuals with symptoms of AUD and MHCs, and subsequent …

Diagnostic Sequence Detection Against A Complex Background Using A Dna Molecular Computation Framework, Adan Leon Myers Y Gutierrez

Nanoscience and Microsystems ETDs

Diagnostic assays are designed to detect a unique analyte profile in a disease of interest. Nucleic acids contain an information-dense sequence, and thus are ideal candidates for unique analytes. The gold-standard of nucleic-acid-based detection is PCR which has high sensitivity, but involves time, expertise, and cost. DNA molecular logic technology holds much promise as an alternative molecular detection method due to the potential to save cost and expertise, while also achieving a high sensitivity. However, nucleic acid detection in biomedical applications carries with it the difficulty of choice of appropriate sequence and potential biological sample background.

This work describes the …

Mixing It Up: The Impact Of Episodic Introgression On The Evolution Of High-Latitude Mesocarnivores, Jocelyn P. Colella

Biology ETDs

At high latitudes, climatic oscillations have triggered repeated episodes of organismal divergence by geographically isolating populations. For terrestrial species, extended isolation in glacial refugia – ice-free regions that enable terrestrial species persistence through glacial maxima – is hypothesized to stimulate allopatric divergence. Alternatively, upon glacial recession, divergent populations expanded from independent glacial refugia and often contacted other diverging populations. In the absence of reproductive isolating mechanisms, this biogeographic process may trigger hybridization and ultimately, gene flow between divergent taxa. My dissertation research aims to understand how these episodic periods of isolation and contact have impacted the evolution of high latitude …

Unsettling Indian Health Services: Secularism, Modern Medicine, & The Reproduction Of The U.S. Settler State Through The 1954 Transfer Act, Jillian Elizabeth Grisel

American Studies ETDs

This thesis takes up the role of secularism in modern medicine as a political doctrine that works in service of settler colonialism. I argue the Declaration of Human Rights and the World Health Organization (WHO) globally institutionalized secular ideologies in the post-World War II environment. This thesis links how this global reordering came to inform U.S. health policy by examining how government officials and medical experts drew from the WHO and framed infectious diseases as a security issue to impose a biomedical order in Indian country. By contextualizing modern medicine within a settler political economy and secular political doctrine, I …

Assessment Of Post-Discharge Health Care Utilization In Infants With Neonatal Opioid Withdrawal Syndrome, Shikhar Shrestha

Pharmaceutical Sciences ETDs

Background/Objectives: Children born to mothers with opioid use disorder often show withdrawal effects characterized by increased stress, hyperirritability, tremors, tachycardia, sleep deprivation, and gastrointestinal discomfort, commonly known as “neonatal opioid withdrawal syndrome” (NOWS). Studies have shown that the effect of NOWS can lead to several health-related disorders later in life leading to increased health care utilization. However, detailed study of post-discharge health care utilization, specifically focusing on encounters with the health care system is currently lacking in the literature. Our objective was to evaluate health care utilization in infants who were diagnosed with NOWS during a one-year follow-up period after …

Role Of Host Cell Β-Catenin During Toxoplasma Gondii Infection, Cameron H. Ranken

Biology ETDs

The microbial pathogen Toxoplasma gondii is an intracellular protozoan that actively invades host cells and simultaneously creates a specialized parasitophorous vacuole within which the parasite lives and replicates. The parasite molecular machinery that drives establishment of the intracellular niche is relatively well known. However, it is now emerging that Toxoplasma exploits less well-understood host cell components to enable successful infection. Here, we examined the role of host Wnt/β-catenin during T. gondii infection. Using human fibroblasts and a mouse dendritic cell line, we found that infection with Toxoplasma stimulated both upregulation and nuclear localization of β-catenin. Using a transwell experimental approach, …

Facial Fluctuating Asymmetry: Developmental Origins And Implications For Long-Term Health, Katelyn Marie Rusk Phd

Anthropology ETDs

Fluctuating asymmetry (FA), characterized by random left-right deviations from perfect symmetry in anatomical structures, is a form of bilateral asymmetry that is thought to reflect underlying developmental instability (DI). DI refers to an organism’s relative ability to buffer against stochastic fluctuations in environmental conditions throughout development. FA is commonly used within evolutionary biology and anthropology as a cumulative indicator of chronic stress exposure during development and its consequences for long-term health. While the FA literature is extensive, there are two primary areas of inquiry that remain incomplete: assessing the full breadth of health correlates of FA across the human life …

Computational Investigation Of The Interactions Between Bioactive Compounds And Biological Assemblies, Tye D. Martin

Biomedical Engineering ETDs

Small, biologically active molecules with unique properties and applications are potential solutions to a wide range of threats to global health including infectious agents and neurodegenerative disease. Experimental studies on a class of oligomeric p-phenylene ethynylenes (OPEs) have shown potential both as bioactive antimicrobials and fluorescent sensing agents for tracking amyloid-β (Aβ) aggregates found in Alzheimer’s Disease (AD). A second type of small molecule with potential applications in AD therapy, curcumin, has been found to interfere with Aβ fibril growth. Curcumin also attenuates Aβ-membrane interactions and Aβ toxicity. Our goal has been to use computational techniques to better understand the …

Improving Proton Pump Inhibitor Prescription Practices As A Means To Decreasing Nosocomial Infections, Jens Langsjoen

Biomedical Sciences ETDs

Proton pump inhibitors (PPIs) are commonly prescribed to treat stomach acid related illnesses, but increase the risk of hospital acquired infections. Measuring hospital PPI overuse trends and provider willingness to adopt PPI reduction interventions can inform the feasibility of reducing PPI overuse. We: (1) interviewed physicians, pharmacists and IT leaders to determine options for hospital PPI reduction, (2) analyzed electronic health record data to determine patterns of PPI overuse, and (3) surveyed providers regarding their willingness to adopt PPI reduction interventions. PPI use was inappropriate in 32% of inpatient encounters locally and 38% nationally. ICU exposure increased the odds of …

Strategies To Combat Drug-Resistant Tuberculosis: Inhalable Microparticles Formulated With Anti-Tubercular Antibiotics And Efflux Pump Inhibitors, Elliott K. Miller

Pharmaceutical Sciences ETDs

Mycobacterium tuberculosis (Mtb) is an intracellular pathogen which can remain dormant within the human body for years (latent tuberculosis), and once active requires extensive multidrug therapies for treatment. Long-term antibiotic(s) exposure have led to the emergence of multidrug-resistant (MDR) and extensively drug-resistant (XDR) strains which require novel treatment approaches to combat Mtb resistance. Mtb may also utilize efflux pumps to expel antibiotics and promote bacterial survival, potentially mediating drug tolerance, which has been hypothesized to contribute to antibiotic resistance. Efflux pump inhibitors (EPIs) such as verapamil (VER) may potentiate effects of first-line anti-tubercular drugs (ATDs) such as rifampicin …

Project ECHO Bibliography

BACKGROUND: Treatment for chronic hepatitis C virus (HCV) has rapidly evolved to simple, well-tolerated, all-oral regimens of direct-acting antivirals (DAAs). There are few data on the epidemiology of HCV in American Indians/Alaska Natives (AI/ANs), a population disproportionately affected by HCV.

METHODS: In this retrospective cohort study, all HCV-infected AI/AN patients treated with DAA therapies between January 1, 2014, and February 24, 2016, in specialty clinics or by primary care clinicians participating in Extension for Community Healthcare Outcomes (ECHO) were included. Demographic, clinical, and virologic data on all patients treated for HCV from pretreatment through sustained virologic response at 12 weeks …

Patterns Of Polysubstance Use Among Those With Tranquilizer Or Sedative Misuse: Predictors And Functional Consequences, Victoria R. Votaw

Psychology ETDs

The misuse of tranquilizer and sedative medications (i.e., use without a prescription or at higher doses/longer periods of time than prescribed) is associated with myriad negative sequalae, such as suicidal behaviors and increased risk of overdose. Yet, prescription tranquilizer and sedative misuse has been largely overlooked by the scientific community, clinicians, and policymakers. We addressed this gap in the literature by characterizing subgroups of individuals with tranquilizer or sedative misuse, based on their patterns of polysubstance use. The present study analyzed data from two samples of individuals with past-month tranquilizer or sedative misuse: respondents of a nationally-representative household survey (general …

A Microfluidics-Based Cross-Flow Filtration Platform For Rapid Processing Of Amphiphilic Biomarkers From Blood, Kiersten D. Lenz

Biomedical Engineering ETDs

Early and accurate detection of bacterial infections can help save lives, prevent the spread of disease, and decrease the overuse of antibiotics. Our team at the Los Alamos National Laboratory has developed novel assays to detect bacterial biomarkers from patient blood at the point-of-care in order to facilitate a universal diagnostic platform. However, these biomarkers are amphiphilic in nature, and this biochemical property causes them to be sequestered by high-density and low-density lipoproteins (HDL and LDL) in the host’s blood. Extraction of the bacterial biomarkers from the lipoprotein complexes is thereby required for the development and deployment of a diagnostic …

Determining The Pathological Effects Of Prenatal Alcohol Exposure On Peripheral Neuropathy Via Spinal And Peripheral Immune Mechanisms, Joshua J. Sanchez

Biomedical Sciences ETDs

Previous studies have suggested that children with Fetal Alcohol Spectrum Disorder (FASD) display hypersensitivity to light touch. In support of this notion, we have demonstrated that applying a chronic constriction injury (CCI) to the sciatic nerve of rats that have prenatal alcohol exposure (PAE) results in heightened sensitivity to light touch, clinically termed allodynia. These observations coincided with heightened glial activation and enhanced peripheral immune reactivity. Considering allodynia is known to be mediated by both peripheral immune responses and spinal glial activation, it is reasonable to speculate that allodynia following PAE may be mediated through an alteration of immune reactivity. …

Exploring Individual Experiences Obtaining Medication-Assisted Treatment For Opioid Use Disorder In Rural New Mexico, Krista L. Scorsone

Nursing ETDs

In the United States, more than 2.5 million people struggle with opioid use disorder. Compared to people living in urban areas, rural residents are twice as likely to overdose from opioid misuse. Reasons for this increase include excessive opioid prescribing and illegal diversion of opioids. This holds true in the rural counties of northern New Mexico, where drug overdose deaths are among the highest in the nation. Although medication-assisted treatment (MAT) with buprenorphine, methadone, or naltrexone is globally accepted as the most effective treatment, it is still accessed half as often rurally. The reasons for this imbalance are unknown, and …

Biomedical Sciences ETDs

Quantitative fluorescence microscopy is a highly technical, swiftly evolving field of methodologies that are uniquely able to probe the nano-scale biological environment. With these optimized, advanced technologies available, scientists and medical providers are equipped to illuminate a plethora of puzzles in science and medicine through the multiplexing and high spatiotemporal resolution offered. Here I first exploit these capabilities to study a rare cancer with multiplex immunohistofluorescence (IHF) to confirm cell type and undocumented protein expression that may have implications for our understanding of the biology of mast cells and the potential efficacy of treatment and symptom management in mast cell …

Determining Mediators Of Naive T Cell Motility And Dc Association In The Lymph Node, Janie Rae Byrum

Biomedical Sciences ETDs

To become activated and perform effector functions, naive T cells move within lymph nodes to scan dendritic cells presenting antigen. Previous work has shown naive T cell activation is promoted by interleukin 7 in vivo, and it does so by regulating the T cell:dendritic cell interaction. Our work identifies a novel role for IL-7 in mediating naive T cell motility in the lymph node and promoting T cell association with DCs. Additionally, we have developed a method for analyzing microscopy images, regionalized normalized mutual information, to assess intercellular associations between T cells and other cells within the lymph node. Dendritic …

Iron-Containing Nanoparticles For The Treatment Of Chrionic Biofilm Infections In Cystic Fibrosis, Leisha M. A. Martin

Nanoscience and Microsystems ETDs

Cystic fibrosis (CF) is the most common genetic disease resulting in the morbidity and mortality of Caucasian children and adults worldwide. Due to a genetic mutation resulting in malfunction of the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) protein, CF patients produce highly viscous mucus in their respiratory tract. This leads to impairment of the mucociliary clearance of inhaled microbes. In addition to reduced microbial clearance, anoxic environmental conditions in the lungs promote biofilm-mode growth of the pathogenic bacterial species Pseudomonas aeruginosa. Chronic infections of P. aeruginosa begin in early childhood and typically persist until respiratory failure and death result. The …

Comparison Of Nylon-Flocked Swab And Dacron Swab Cytology For Anal Hsil Detection In Transgender Women And Gay, Bisexual, And Other Men Who Have Sex With Men, Dorothy J. Wiley, Hilary K. Hsu, Martha A. Ganser, Jenny Brook, David A. Elashoff, Stephen A. Young, Nancy E. Joste, Ronald Mitsuyasu, Teresa M. Darragh, David H. Morris, Otoniel M. Martínez-Maza, Roger Detels, Jian Yu Rao, Robert K. Bolan, Eric T. Shigeno, Ernesto Rodriguez, Matthrew G. Moran

Pathology Research and Scholarship

BACKGROUND: An anal histological high-grade squamous intraepithelial lesion (hHSIL) is an anal cancer precursor. Experts recommend Dacron swab anal cytology as a primary screen for anal hHSILs, especially among human immunodeficiency virus-infected and -uninfected men who have sex with men (MSM). Studies have shown that Dacron cytology inaccurately predicts anal hHSILs and results in unnecessary diagnostic procedures. Nylon-flocked (NF) swabs have been shown to trap pathogens and cells well. Thus, this study compared test characteristics of anal cytology using NF and Dacron swab collection protocols to predict anal hHSILs.

METHODS: A single-visit, randomized clinical trial compared NF and Dacron swab …

Diagnosis Of Leprosy Using Sural Nerve Biopsy Findings: A Case Report, Bridgette M. Love, Deana Mercer, Amber West, Karen S. Santacruz, Elizabeth A. Mikola

UNM Orthopaedic Research Journal

Leprosy, also known as Hansen disease, is an uncommon chronic disease caused by the slowly growing acid-fast bacilli, Mycobacterium leprae. Leprosy has tropism for peripheral nerves and skin and can also be found in the upper respiratory tract, eyes, and nasal mucosa. When left untreated, there can be considerable nerve damage resulting in paralysis, blindness, and the crippling of hands and feet. Although infrequent in the United States, leprosy has been diagnosed in patients exposed to armadillos, an animal reservoir. We describe an 80-year-old man who presented with a 6-year history of chronic erythematous, macular rash, and progressive symmetric sensory …

UNM Orthopaedic Research Journal

Background: The Centers for Medicare and Medicaid (CMS) has begun mandating infection surveillance at surgical sites, which started in hospitals and is now in ambulatory surgical centers (ASCs). We found a 0.1% increase in infection rate between 2005 and 2007, which prompted us to examine the issue further. The purpose of the current study was to summarize the results of an investigation after an outbreak of infection at our ASC, specifically attempting to identify a common pathogen, vector, or unknown lapses in infection prevention. Additionally, we relate our experience to current trends in infection prevention at ASCs by examining the …

Strengthening The Health Workforce Through The Echo Stages Of Participation: Participants' Perspectives On Key Facilitators And Barriers, Suzuho Shimasaki, Erin Bishop, Michelle Guthrie, John F Fred Thomas

Project ECHO Bibliography

INTRODUCTION: Project Extension for Community Health Outcomes (ECHO) was originally developed by the University of New Mexico's Health Science Center (UNMHSC) to build the capacities of primary-care providers and to increase specialty-care access to rural and underserved populations. ECHO Colorado, a replication site at the University of Colorado Anschutz Medical Campus (CUAMC), was developed with the same purpose and to help build the health workforce of Colorado. The CUAMC and its community-based partners recognized that by reducing unnecessary referrals to the medical campus and building primary-care capacity in communities, both would increase their scope and expand overall capacity. This study …
