INTRODUCTION: The relation between traumatic brain injury (TBI), its acute and chronic symptoms, and the potential for remote neurodegenerative disease is a priority for military research. Structural and functional connectivity (FC) of the basal ganglia, involved in motor tasks such as walking, are altered in some samples of Service Members and Veterans with TBI, but any behavioral implications are unclear and could further depend on the context in which the TBI occurred.

METHODS: In this study, FC from caudate and pallidum seeds was measured in Service Members and Veterans with a history of mild TBI that occurred during combat deployment, …

Parkinson's disease (PD) is the fastest-growing neurodegenerative disorder, currently affecting ~7 million people worldwide. PD is clinically and genetically heterogeneous, with at least 10% of all cases explained by a monogenic cause or strong genetic risk factor. However, the vast majority of our present data on monogenic PD is based on the investigation of patients of European White ancestry, leaving a large knowledge gap on monogenic PD in underrepresented populations. Gene-targeted therapies are being developed at a fast pace and have started entering clinical trials. In light of these developments, building a global network of centers working on monogenic PD, …

Hippocampal Δfosb Expression Is Associated With Cognitive Impairment In A Subgroup Of Patients With Childhood Epilepsies, Chia-Hsuan Fu, Jason C You, Carrie Mohila, Robert A Rissman, Daniel Yoshor, Angela N Viaene, Jeannie Chin

Faculty, Staff and Students Publications

Epilepsy is a chronic neurological disorder characterized by recurrent seizures, and is often comorbid with other neurological and neurodegenerative diseases, such as Alzheimer's disease (AD). Patients with recurrent seizures often present with cognitive impairment. However, it is unclear how seizures, even when infrequent, produce long-lasting deficits in cognition. One mechanism may be seizure-induced expression of ΔFosB, a long-lived transcription factor that persistently regulates expression of plasticity-related genes and drives cognitive dysfunction. We previously found that, compared with cognitively-intact subjects, the activity-dependent expression of ΔFosB in the hippocampal dentate gyrus (DG) was increased in individuals with mild cognitive impairment (MCI) and …

Δfosb Is Part Of A Homeostatic Mechanism That Protects The Epileptic Brain From Further Deterioration, Jerome Clasadonte, Tania Deprez, Gabriel S Stephens, Georges Mairet-Coello, Pierre-Yves Cortin, Maxime Boutier, Aurore Frey, Jeannie Chin, Marek Rajman

Faculty, Staff and Students Publications

Activity induced transcription factor ΔFosB plays a key role in different CNS disorders including epilepsy, Alzheimer's disease, and addiction. Recent findings suggest that ΔFosB drives cognitive deficits in epilepsy and together with the emergence of small molecule inhibitors of ΔFosB activity makes it an interesting therapeutic target. However, whether ΔFosB contributes to pathophysiology or provides protection in drug-resistant epilepsy is still unclear. In this study, ΔFosB was specifically downregulated by delivering AAV-shRNA into the hippocampus of chronically epileptic mice using the drug-resistant pilocarpine model of mesial temporal epilepsy (mTLE). Immunohistochemistry analyses showed that prolonged downregulation of ΔFosB led to exacerbation …

Faculty, Staff and Students Publications

INTRODUCTION: Cerebral malaria is one of the most severe manifestations of malaria and is a leading cause of acquired neurodisability in African children. Recent studies suggest acute kidney injury (AKI) is a risk factor for brain injury in cerebral malaria. The present study evaluates potential mechanisms of brain injury in cerebral malaria by evaluating changes in cerebrospinal fluid measures of brain injury with respect to severe malaria complications. Specifically, we attempt to delineate mechanisms of injury focusing on blood-brain-barrier integrity and acute metabolic changes that may underlie kidney-brain crosstalk in severe malaria.

METHODS: We evaluated 30 cerebrospinal fluid (CSF) markers …

Sex-Specific Associations Between Urinary Bisphenols Concentrations During Pregnancy And Problematic Child Behaviors At Age 2 Years, Sarah Dee Geiger, Salma Musaad, Jennifer Hill, Andréa Aguiar, Susan Schantz

Faculty, Staff and Students Publications

Effects of prenatal bisphenol A (BPA) exposure on child behavior are mixed with some reports suggesting increased problematic behaviors in girls (e.g., aggression and emotional reactivity) and in boys (i.e., externalizing behaviors), while other reports suggest decreased problematic behaviors in girls. Little is known about the potential impact of pregnancy bisphenol S (BPS) exposure on child behavior. In a prospective cohort study (n=68), five maternal spot urine samples collected across pregnancy were pooled and analyzed for BPA and BPS. Child behavior at 2 years was assessed using the Child Behavior Checklist (CBCL). Linear regression models were used to assess associations …

Metformin is the first-line treatment for type 2 diabetes (T2D) in youth but with limited sustained glycemic response. To identify common variants associated with metformin response, we used a genome-wide approach in 506 youth from the Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) study and examined the relationship between T2D partitioned polygenic scores (pPS), glycemic traits, and metformin response in these youth. Several variants met a suggestive threshold (P < 1 × 10−6), though none including published adult variants reached genome-wide significance. We pursued replication of top nine variants in three cohorts, and rs76195229 in ATRNL1 was associated with worse metformin response in the Metformin Genetics Consortium (n = 7,812), though statistically not being significant after Bonferroni correction (P …

We retrospectively chose patients from our pediatric pulmonary clinic who had poorly controlled asthma and prescribed ICS daily. For the study period, we examined the number of corticosteroid courses, emergency room visits, hospital admissions, symptom history, and pulmonary function tests.

RESULTS: Thirty-four patients who satisfied the inclusion criteria began the intervention. Preintervention, there were a mean number of 2.6 oral corticosteroid courses compared to 2 courses in the year following …

Heterologous Mrna-Protein Vaccination With Tc24 Induces A Robust Cellular Immune Response Against Trypanosoma Cruzi, Characterized By An Increased Level Of Polyfunctional Cd8+ T-Cells, Cristina Poveda, Ana Carolina Leão, Chiara Mancino, Francesca Taraballi, Yi-Lin Chen, Rakesh Adhikari, Maria Jose Villar, Rakhi Kundu, Duc M Nguyen, Leroy Versteeg, Ulrich Strych, Peter J Hotez, Maria Elena Bottazzi, Jeroen Pollet, Kathryn M Jones

Faculty, Staff and Students Publications

Tc24 is a Trypanosoma cruzi-derived flagellar protein that, when formulated with a TLR-4 agonist adjuvant, induces a balanced immune response in mice, elevating IgG2a antibody titers and IFN-γ levels. Furthermore, vaccination with the recombinant Tc24 protein can reduce parasite levels and improve survival during acute infection. Although some mRNA vaccines have been proven to elicit a stronger immune response than some protein vaccines, they have not been used against T. cruzi. This work evaluates the immunogenicity of a heterologous prime/boost vaccination regimen using protein and mRNA-based Tc24 vaccines. Mice (C57BL/6) were vaccinated twice subcutaneously, three weeks apart, with …

Immunomodulatory Proteins From Hookworms Reduce Cardiac Inflammation And Modulate Regulatory Responses In A Mouse Model Of Chronic Trypanosoma Cruzi Infection, Kathryn M Jones, Bin Zhan, Keenan J Ernste, Maria Jose Villar, Nalini Bisht, Duc Nguyen, Li-Yen Chang, Cristina Poveda, Gonteria J Robinson, Akshar J Trivedi, Colby J Hofferek, William K Decker, Vanaja Konduri

Faculty, Staff and Students Publications

Introduction

Hookworms are parasitic helminths that secrete a variety of proteins that induce anti-inflammatory immune responses, stimulating increased CD4+Foxp3+ regulatory T cells and IL-10 production. Hookworm-derived recombinant proteins AIP-1 and AIP-2 have been shown to reduce inflammation in mouse models of inflammatory bowel disease and inflammatory airway disease by inducing CD4+Foxp3+ cells and IL-10 production. In contrast, chronic infection with the protozoal parasite Trypanosoma cruzi, the causative agent of Chagas disease, leads to chronic inflammation in tissues. Persistence of the parasites in tissues drives chronic low-grade inflammation, with increased infiltration of inflammatory cells into the heart, accompanied by increased …

Prefrontal circuits in the human brain play an important role in cognitive and affective processing. Neuromodulation therapies delivered to certain key hubs within these circuits are being used with increasing frequency to treat a host of neuropsychiatric disorders. However, the detailed neurophysiological effects of stimulation to these hubs are largely unknown. Here, we performed intracranial recordings across prefrontal networks while delivering electrical stimulation to two well-established white matter hubs involved in cognitive regulation and depression: the subcallosal cingulate (SCC) and ventral capsule/ventral striatum (VC/VS). We demonstrate a shared frontotemporal circuit consisting of the ventromedial prefrontal cortex, amygdala, and lateral orbitofrontal …

Modeling Suicidality With Multimodal Impulsivity Characterization In Participants With Mental Health Disorder, Nidal Moukaddam, Bishal Lamichhane, Ramiro Salas, Wayne Goodman, Ashutosh Sabharwal

Faculty, Staff and Students Publications

INTRODUCTION: Suicide is one of the leading causes of death across different age groups. The persistence of suicidal ideation and the progression of suicidal ideations to action could be related to impulsivity, the tendency to act on urges with low temporal latency, and little forethought. Quantifying impulsivity could thus help suicidality estimation and risk assessments in ideation-to-action suicidality frameworks.

METHODS: To model suicidality with impulsivity quantification, we obtained questionnaires, behavioral tests, heart rate variability (HRV), and resting state functional magnetic resonance imaging measurements from 34 participants with mood disorders. The participants were categorized into three suicidality groups based on their …

Optimizing Human Performance In Extreme Environments Through Precision Medicine: From Spaceflight To High-Performance Operations On Earth, Michael A Schmidt, Jeffrey A Jones, Christopher E Mason

Faculty, Staff and Students Publications

Humans operating in extreme environments often conduct their operations at the edges of the limits of human performance. Sometimes, they are required to push these limits to previously unattained levels. As a result, their margins for error in execution are much smaller than that found in the general public. These same small margins for error that impact execution may also impact risk, safety, health, and even survival. Thus, humans operating in extreme environments have a need for greater refinement in their preparation, training, fitness, and medical care. Precision medicine (PM) is uniquely suited to address the needs of those engaged …

Methods: A systematic review qualitative assessment of five observational studies using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines protocol was performed.

Results: It was concluded that lead caps significantly reduce radiation exposure to the head, even when a ceiling-mounted lead shield was present.

Conclusion: Although newer protective systems are being …

The Use Of Reframing: Increasing The Importance Of Lifestyle Medicine, Molly R Vega, Saad Nadeem, Elizabeth M Vaughan, Craig A Johnston

Faculty, Staff and Students Publications

Lifestyle behavior modification is an essential component to prevention and treatment of non-communicable diseases worldwide. For the last 40 years, studies have recognized that there is suboptimal training of physicians in lifestyle medicine and its implementation in clinical settings. The lack of nutrition and exercise counseling occurring in the medical office does not reflect the high level of evidence supporting its use. Lifestyle behavior counseling is complex; as are the individualized needs of patients. Therefore, we suspect that the lack of knowledge in nutrition and exercise prescriptions are not the only barriers to providing optimal care. Reframing lifestyle medicine interventions …

Emergency Department Presentations Of Diabetic Ketoacidosis In A Large Cohort Of Children, Lise E Nigrovic, Nathan Kuppermann, Simona Ghetti, Jeff E Schunk, Michael J Stoner, Arleta Rewers, Julie K Mcmanemy, Kimberly S Quayle, Jennifer L Trainor, Leah Tzimenatos, Jonathan E Bennett, Maria Y Kwok, Sage R Myers, Kathleen M Brown, T Charles Casper, Cody S Olsen, Nicole S Glaser

Faculty, Staff and Students Publications

Background: Diabetic ketoacidosis (DKA) is a potentially life-threatening complication of childhood diabetes. However, the influence of demographic factors on presentation are not well-defined.

Methods: We included children from 12 centers who were < 18 years with DKA (glucose > 300 mg/dL, serum pH < 7.25, or serum bicarbonate < 15 mEq/L) enrolled in the Pediatric Emergency Care Applied Research Network (PECARN) Fluid Therapies Under Investigation in DKA (FLUID) Trial. Data were also collected for children who presented to the centers during the enrollment period but were not enrolled due to disease or treatment-related reasons. We compared demographic, clinical, and biochemical findings among children with newly and previously diagnosed diabetes and children in different age groups.

Results: Of the 1,679 DKA episodes in 1,553 children, 799 (47.5%) episodes occurred in children with newly diagnosed diabetes and 396 (23.6%) were severe (pH < 7.1). Newly diagnosed children < 6 years of age were not more likely to have severe DKA in terms of pH, but had more severe hypocarbia and higher blood urea nitrogen levels, factors previously associated with the risk of cerebral injury. Lower socioeconomic status (SES) (based on family income and maternal education level) were associated with more severe DKA in new onset children, and recurrent DKA in the previously diagnosed children.

Conclusions: Greater efforts are needed to identify the children with diabetes early and to prevent recurrent DKA, particularly among children in low-SES groups. Young children with DKA may need more intensive monitoring due to higher risk of cerebral injury.

Comparison Of Gis Methods For Estimating The Social Vulnerability In Response To Natural Hazards In The West Part Of The City Of Tualatin, Alex Troy

Geography Masters Research Papers

The influence of natural hazards on social vulnerability is an important topic in the risk analysis of natural disasters in the human-environment system. Due to the difficulty of directly measuring social vulnerability, composite indexes are used as a surrogate. Social vulnerability indexes attempt to characterize access to societal and local social services during or after disastrous events, using various indicators such as age, gender, ethnicity, socioeconomic status, housing organization, access to shelters, and medical facilities. Geographic information systems (GIS) are used for vulnerability analysis due to their visualization methods and demographic data analysis. However, limitations in GIS applications for social …

Malignant Insulinoma Arising From Nonfunctioning Pancreatic Neuroendocrine Tumor, Ritodhi Chatterjee, Basim Ali, Son H Nguyen, Rui Chen, Yvonne H Sada

Faculty, Staff and Students Publications

Pancreatic neuroendocrine tumors are rare neoplasms characterized into nonfunctioning (NF-PNET) and functioning (F-PNET) subtypes. F-PNETs typically involve overt symptoms related to excessive hormone secretion but may rarely present first as NF-PNETs with delayed transformation. We present a patient with known NF-PNET with liver metastases who developed hypoglycemia 2 years after initial diagnosis due to malignant insulinoma. Hypoglycemia was refractory to continuous dextrose but improved temporarily after diazoxide and hepatic artery embolization. Malignant insulinomas are usually metastatic at presentation and portend poor prognosis. Hypoglycemia may be medically managed with steroids, somatostatin analogues, and diazoxide, along with therapies to reduce tumor burden.

Publications and Research

Study of the timing and location for mRNA translation across model systems has begun to shed light on molecular events fundamental to such processes as intercellular communication, morphogenesis, and body pattern formation. In D. melanogaster, the posterior mRNA determinant, oskar, is transcribed maternally but translated only when properly localized at the oocyte’s posterior cortex. Two effector proteins, Bruno1 and Cup, mediate steps of oskar mRNA regulation. The current model in the field identifies Bruno1 as necessary for Cup’s recruitment to oskar mRNA and indispensable for oskar’s translational repression. We now report that this Bruno1-Cup interaction leads …

Single Inclusive Hadron Production In Dis At Small X: Next To Leading Order Corrections, Filip Bergabo, Jamal Jalilian-Marian

Publications and Research

We calculate the one-loop corrections to single inclusive hadron production in Deep Inelastic Scattering (DIS) at small x in the forward rapidity region using the Color Glass Condensate formalism. We show that the divergent parts of the next to leading order (NLO) corrections either cancel among each other or lead to x (rapidity) evolution of the leading order (LO) dipole cross section according to the JIMWLK evolution equation and DGLAP evolution of the parton-hadron fragmentation function. The remaining finite parts constitute the NLO (α_s) corrections to the LO single inclusive hadron production cross section in DIS at …

Active Learning For Efficient Soil Monitoring In Large Terrain With Heterogeneous Sensor Network, Hui Chen, Ju Wang

Publications and Research

Soils are a complex ecosystem that provides critical services, such as growing food, supplying antibiotics, filtering wastes, and maintaining biodiversity; hence monitoring soil health and domestication is required for sustainable human development. Low-cost and high-resolution soil monitoring systems are challenging to design and build. Compounded by the sheer size of the monitoring area of interest and the variety of biological, chemical, and physical parameters to monitor, naive approaches to adding or scheduling more sensors will suffer from cost and scalability problems. We investigate a multi-robot sensing system integrated with an active learning-based predictive modeling technique. Taking advantage of advances in …
