Once the patient arrives, the pharmacy team conducts an interview that involves a medication reconciliation, medication assessment, monitoring, and therapeutic adjustments if needed. We get …

Policy Stringency, Political Conditions, And Public Performances Of Pandemic Control: An International Comparison, Dan Chen, Yong Li, Jiebing Wu

Political Science Faculty Publications

What factors might explain the cross-country variations in COVID-19 public performances and what lessons can be drawn to be better-prepared for future pandemics? This study focuses on the effects of policy stringency on COVID-19 public health outcomes to gain insights into national-level state responses to COVID-19 and the conditions for their effectiveness. Using data from 136 countries comprising 91.4% of the global population, we find that more stringent policies lead to lower infection and death rates. More importantly, the negative effects of restrictive policies on infection and death rates are moderated by political trust and democracy levels, possibly through the …

The periodic emergence of SARS-CoV-2 variants of concern (VOCs) with unpredictable clinical severity and ability to escape preexisting immunity emphasizes the continued need for antiviral interventions. Two small molecule inhibitors, molnupiravir (MK-4482), a nucleoside analog, and nirmatrelvir (PF-07321332), a 3C-like protease inhibitor, have recently been approved as monotherapy for use in high-risk patients with COVID-19. As preclinical data are only available for rodent and ferret models, here we assessed the efficacy of MK-4482 and PF-07321332 alone and in combination against infection with the SARS-CoV-2 Delta VOC in the rhesus macaque COVID-19 model. Macaques were infected with the SARS-CoV-2 Delta variant …

County-Level Social Determinants Of Health And Covid-19 Health Outcomes, Bret R. Lyman

Theses and Dissertations

Social determinants of health are associated with a variety of negative health outcomes, including COVID-19 morbidity and mortality. However, most research evaluating this relationship have been case studies, retrospective cohort studies, and case series studies and/or have used use analytic techniques, such as linear regression, that can struggle to adequately model the social determinants' complex nature. This study used United States county-level social determinants of health data and March 2020-December 2020 COVID-19 morbidity and mortality data. Structural equation modeling was used to develop a latent measurement model for the social determinants of health. Substantial cross-loadings among the social determinants of …

Alternative Splicing Mediates The Compensatory Upregulation Of Mbnl2 Upon Mbnl1 Loss-Of-Function, Larissa Nitschke, Rong-Chi Hu, Andrew N Miller, Lathan Lucas, Thomas A Cooper

Faculty, Staff and Students Publications

Loss of gene function can be compensated by paralogs with redundant functions. An example of such compensation are the paralogs of the Muscleblind-Like (MBNL) family of RNA-binding proteins that are sequestered and lose their function in Myotonic Dystrophy Type 1 (DM1). Loss of MBNL1 increases the levels of its paralog MBNL2 in tissues where Mbnl2 expression is low, allowing MBNL2 to functionally compensate for MBNL1 loss. Here, we show that loss of MBNL1 increases the inclusion of Mbnl2 exon 6 and exon 9. We find that inclusion of Mbnl2 exon 6 increases the translocation of MBNL2 to the nucleus, while …

A Cryptic Oxidoreductase Safeguards Oxidative Protein Folding In Corynebacterium Diphtheriae, Melissa E Reardon-Robinson, Minh Tan Nguyen, Belkys C Sanchez, Jerzy Osipiuk, Christian Rückert, Chungyu Chang, Bo Chen, Rahul Nagvekar, Andrzej Joachimiak, Andreas Tauch, Asis Das, Hung Ton-That

Faculty, Staff and Student Publications

In many gram-positive Actinobacteria, including Actinomyces oris and Corynebacterium matruchotii, the conserved thiol-disulfide oxidoreductase MdbA that catalyzes oxidative folding of exported proteins is essential for bacterial viability by an unidentified mechanism. Intriguingly, in Corynebacterium diphtheriae, the deletion of mdbA blocks cell growth only at 37 °C but not at 30 °C, suggesting the presence of alternative oxidoreductase enzyme(s). By isolating spontaneous thermotolerant revertants of the mdbA mutant at 37 °C, we obtained genetic suppressors, all mapped to a single T-to-G mutation within the promoter region of tsdA, causing its elevated expression. Strikingly, increased expression of tsdA—via …

Lactogenic immunity is important for the protection of piglets against many pathogens including porcine epidemic diarrhea virus. Circulating neutralizing antibodies levels in sow sera may help determine if a detectable immune response could confer protection to piglets. Neutralizing antibodies can be detected through various diagnostic assays. This study evaluated the diagnostic characteristics of two neutralizing antibody assays for porcine epidemic diarrhea virus neutralizing antibodies in serum of challenged gilts. Four treatment groups, control, non-vaccinated, vaccinated prior to challenge, and vaccinated following challenge, were comprised of 20 gilts. Serum sample were collected from each gilt prior to and following challenge with …

Survival of pediatric AML remains poor despite maximized myelosuppressive therapy. The pneumocystis jiroveci pneumonia (PJP)-treating medication atovaquone (AQ) suppresses oxidative phosphorylation (OXPHOS) and reduces AML burden in patient-derived xenograft (PDX) mouse models, making it an ideal concomitant AML therapy. Poor palatability and limited product formulations have historically limited routine use of AQ in pediatric AML patients. Patients with de novo AML were enrolled at two hospitals. Daily AQ at established PJP dosing was combined with standard AML therapy, based on the Medical Research Council backbone. AQ compliance, adverse events (AEs), ease of administration score (scale: 1 (very difficult)-5 (very easy)) …

PURPOSE: Squamous cell carcinoma of the anus (SCCA) incidence and mortality rates are rising in the United States. Understanding state-level incidence and mortality patterns and associations with smoking and AIDS prevalence (key risk factors) could help unravel disparities and provide etiologic clues.

METHODS: Using the US Cancer Statistics and the National Center for Health Statistics data sets, we estimated state-level SCCA incidence and mortality rates. Rate ratios (RRs) were calculated to compare incidence and mortality in 2014-2018 versus 2001-2005. The correlations between SCCA incidence with current smoking (from the Behavioral Risk Factor Surveillance System) and AIDS (from the HIV Surveillance …

Decision-Making Under Risk And Theory Of Mind In Adolescent Offenders In Provisional Deprivation Of Liberty, Rubens José Loureiro, Flavio Takemi Kataoka, Thiago Wendt Viola, Gisele Iesbich Vargas, Breno Sanvicente-Vieira, Rodrigo Grassi-Oliveira, Bruno Kluwe-Schiavon

Faculty, Staff and Student Publications

INTRODUCTION: Delinquent behaviors are risky behaviors that increase during puberty and reach their highest peak in late adolescence. It has been proposed that poor decision-making and theory of mind (ToM) are key cognitive processes implicated with delinquency during adolescence, affecting evaluation of risks and impairing appreciation of social norms. Nevertheless, it is not yet clear whether adolescent offenders who are subjected to provisional deprivation of liberty due to conflict with the law (adolescents in conflict with the law [ACL]) might, in fact, present a specific profile with regard to these cognitive processes.

OBJECTIVES: To assess deliberative decision-making and ToM among …

The coronavirus disease 2019 (COVID-19) pandemic and associated increase in family care responsibilities resulted in unsustainable personal and professional workloads for infectious diseases (ID) faculty on the front lines. This was especially true for early-stage faculty (ESF), many of whom had caregiving responsibilities. In addition, female faculty, underrepresented in medicine and science faculty and particularly ESF, experienced marked declines in research productivity, which significantly impacts career trajectories. When combined with staffing shortages due to an aging workforce and suboptimal recruitment and retention in ID, these work-life imbalances have brought the field to an inflection point. We propose actionable recommendations and …

BACKGROUND: People with human immunodeficiency virus (HIV) with and without hepatitis C virus (HCV) coinfection had poor outcomes after liver transplant (LT). Integrase strand transfer inhibitors (INSTIs) and direct-acting antivirals (DAAs) have changed the treatment landscape for HIV and HCV, respectively, but their impact on LT outcomes remains unclear.

METHODS: This retrospective analysis of adults with HIV monoinfection (n = 246) and HIV/HCV coinfection (n = 286) who received LT compared mortality in patients with HIV who received LT before versus after approval of INSTIs and in patients with HIV/HCV coinfection who received LT before versus after approval of DAAs. …

Was Kaposi’S Sarcoma-Associated Herpesvirus Introduced Into China Via The Ancient Silk Road? An Evolutionary Perspective, Zhenqiu Liu, Qiwen Fang, Jialu Zuo, Veenu Minhas, Charles Wood, Na He, Tiejun Zhang

Nebraska Center for Virology: Faculty Publications

Kaposi’s sarcoma-associated herpesvirus (KSHV) has become widely dispersed worldwide since it was first reported in 1994, but the seroprevalence of KSHV varies geographically. KSHV is relatively ubiquitous in Mediterranean areas and the Xinjiang Uygur Autonomous Region, China. The origin of KSHV has long been puzzling. In the present study, we collected and analysed 154 KSHV ORF-K1 sequences obtained from samples originating from Xinjiang, Italy, Greece, Iran and southern Siberia using Bayesian evolutionary analysis in BEAST to test the hypothesis that KSHV was introduced into Xinjiang via the ancient Silk Road. According to the phylogenetic analysis, 72 sequences were subtype A …

Batf2 Promotes Hsc Myeloid Differentiation By Amplifying Ifn Response Mediators During Chronic Infection, Duy T Le, Marcus A Florez, Pawel Kus, Brandon T Tran, Bailee Kain, Yingmin Zhu, Kurt Christensen, Antrix Jain, Anna Malovannaya, Katherine Y King

Faculty, Staff and Students Publications

Basic leucine zipper ATF-like transcription factor 2 (BATF2), an interferon-activated immune response regulator, is a key factor responsible for myeloid differentiation and depletion of HSC during chronic infection. To delineate the mechanism of BATF2 function in HSCs, we assessed Batf2 KO mice during chronic infection and found that they produced less pro-inflammatory cytokines, less immune cell recruitment to the spleen, and impaired myeloid differentiation with better preservation of HSC capacity compared to WT. Co-IP analysis revealed that BATF2 forms a complex with JUN to amplify pro-inflammatory signaling pathways including CCL5 during infection. Blockade of CCL5 receptors phenocopied Batf2 KO differentiation …

Disseminated Juvenile Xanthogranuloma With A Novel Myh9-Flt3 Fusion Presenting As A Blueberry Muffin Rash In A Neonate., Emily E. Clark, Mollie Walton, Lionel M L Chow, J Todd Boyd, M David Yohannan, Shreyas Arya

Manuscripts, Articles, Book Chapters and Other Papers

Juvenile xanthogranuloma (JXG) is a benign proliferative histiocytic disorder of the dendritic cell phenotype. It mostly presents in the pediatric age group as a solitary skin lesion. We describe a rare case of an infant born with disseminated JXG who presented with a blueberry muffin rash at birth. A term infant was noted to have multiple petechiae, purple nodules, and macules (1 mm-2 cm in diameter) and hepatosplenomegaly, at the time of birth. Further investigations revealed thrombocytopenia and direct hyperbilirubinemia and a magnetic resonance imaging showed scattered tiny foci of restricted diffusion in multiple areas of the brain. Patient received …

The induction of proinflammatory T cells by dendritic cell (DC) subtypes is critical for antitumor responses and effective immune checkpoint blockade (ICB) therapy. Here, we show that human CD1c+CD5+ DCs are reduced in melanoma-affected lymph nodes, with CD5 expression on DCs correlating with patient survival. Activating CD5 on DCs enhanced T cell priming and improved survival after ICB therapy. CD5+ DC numbers increased during ICB therapy, and low interleukin-6 (IL-6) concentrations promoted their de novo differentiation. Mechanistically, CD5 expression by DCs was required to generate optimally protective CD5hi T helper and CD8+ T cells; further, deletion of CD5 from T …

High Prep Uptake And Objective Longitudinal Adherence Among Hiv-Exposed Women With Personal Or Partner Plans For Pregnancy In Rural Uganda: A Cohort Study, Lynn T. Matthews, Esther Atukunda, Moran Owembabazi, Christina Psaros, David Bangsberg, Multiple Additional Authors

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background

In Uganda, fertility rates and adult HIV prevalence are high, and many women conceive with partners living with HIV. Pre-exposure prophylaxis (PrEP) reduces HIV acquisition for women and, therefore, infants. We developed the Healthy Families-PrEP intervention to support PrEP use as part of HIV prevention during periconception and pregnancy periods. We conducted a longitudinal cohort study to evaluate oral PrEP use among women participating in the intervention.

Methods and findings

We enrolled HIV–negative women with plans for pregnancy with a partner living, or thought to be living, with HIV (2017 to 2020) to evaluate PrEP use among women participating …

Performance Of A Sars-Cov-2 Rt-Pcr Assay With Non-Traditional Specimen Types, Subathra Marimuthu, Holly Aliesky, Heather Ness, Daniya Sheikh, Sathya Rashmit, Dawn Balcom, Leslie A. Wolf

The University of Louisville Journal of Respiratory Infections

During the first two years of the coronavirus disease 2019 (COVID-19) pandemic, nasopharyngeal (NP) specimens were the gold standard for clinical diagnostic testing. As information about the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causing the pandemic continued to be shared, it was clear that the virus could be detected in other specimen types during an active infection. The University of Louisville Infectious Diseases Laboratory accepted non-traditional specimen types, most without a paired, positive NP result, for research purposes only to support local epidemiology efforts. A real-time reverse transcription-polymerase chain reaction (RT-PCR) assay originally validated for NP specimens was used …
