Comparing Men Who Have Sex With Men And Transgender Women Who Use Grindr, Other Similar Social And Sexual Networking Apps, Or No Social And Sexual Networking Apps: Implications For Recruitment And Health Promotion, Christina J. Sun, Erin L. Sutfin, Laura H. Bachmann, Jason Stowers, Scott D. Rhodes

OHSU-PSU School of Public Health Faculty Publications and Presentations

Objective: Researchers and public health professionals have increased their attention to GPS-based social and sexual networking applications (apps) tailored to gay, bisexual, and other men who have sex with men (MSM) and transgender women. These populations continue to be disproportionately affected by HIV in the United States; therefore, these apps, in particular Grindr, have become an important sampling venue for the recruitment of HIV-related research participants. As such, it is essential to identify differences among app users to avoid potential sampling bias. This paper seeks to identify differences in MSM and transgender women who use Grindr and those who …

OHSU-PSU School of Public Health Faculty Publications and Presentations

Academic health centers (AHCs) are under increased pressure to demonstrate the effectiveness of their community-engaged activities, but there are no common metrics for evaluating community engagement in AHCs. Eight AHCs piloted the Institutional Community Engagement Self-Assessment (ICESA), a two-phase project to assess community-engagement efforts. The first phase uses a framework developed by the University of Rochester Medical Center, which utilizes structure, process, and outcome criteria to map CE activities. The second phase uses the Community-Campus Partnerships for Health (CCPH) Self-Assessment to identify institutional resources for community engagement, and potential gaps, to inform community engagement goal-setting. The authors conducted a structured, …

Importance Neuraxial labor analgesia is recognized as the most effective method of providing pain relief during labor. Little is known about variation in the rates of neuraxial analgesia across US states. Identifying the presence and extent of variation may provide insights into practice variation and may indicate where access to neuraxial analgesia is inadequate. Objective To test the hypothesis that variation exists in neuraxial labor analgesia use among US states. Design, Setting, and Participants Retrospective, population …

Comparative Genetic And Genomic Analysis Of The Novel Fusellovirus Sulfolobus Spindle-Shaped Virus 10, David Andrew Goodman, Kenneth M. Stedman

Biology Faculty Publications and Presentations

Viruses that infect thermophilic Archaea are unique in both their structure and genetic makeup. The lemon-shaped fuselloviruses—which infect members of the order Sulfolobales, growing optimally at 80 C and pH 3—are some of the most ubiquitous and best studied viruses of the thermoacidophilic Archaea. Nonetheless, much remains to be learned about these viruses. In order to investigate fusellovirus evolution, we have isolated and characterized a novel fusellovirus, Sulfolobus spindle-shaped virus 10 (formerly SSV-L1). Comparative genomic analyses highlight significant similarity with both SSV8 and SSV9, as well as conservation of promoter elements within the Fuselloviridae. SSV10 encodes five ORFs with no …

Focus Groups To Increase The Cultural Acceptability Of A Contingency Management Intervention For American Indian And Alaska Native Communities, Katherine A. Hirchak, Emily Leickly, Jalene Herron, Jennifer Shaw, Jordan Skalisky, Lisa G. Dirks, Jaedon P. Avey, Multiple Additional Authors

Psychology Faculty Publications and Presentations

Introduction

Many American Indian and Alaska Native (AI/AN) people seek evidence-based, cost-effective, and culturally acceptable solutions for treating alcohol use disorders. Contingency management (CM) is a feasible, low-cost approach to treating alcohol use disorders that uses “reinforcers” to promote and support alcohol abstinence. CM has not been evaluated among AI/AN communities. This study explored the cultural acceptability of CM and adapted it for use in diverse AI/AN communities.

Methods

We conducted a total of nine focus groups in three AI/AN communities: a rural reservation, an urban health clinic, and a large Alaska Native healthcare system. Respondents included adults …

Mitigating Early Loss Of Community Participation In Early Psychosis Services: State Of The Science, Tamara G. Sale, Dora M. Raymaker, Mariam Rija, Veronica Gould, Christina Wall, Ryan P. Melton

School of Social Work Faculty Publications and Presentations

In the early stages of treatment for psychosis, community engagement and social networks are threatened through a combination of symptomology and negative messages and reactions from the environment which may result in internalized stigma, disempowerment, and prolonged isolation. While treatment programs attempt to mitigate these factors, ambivalence toward treatment and the basic concept of psychosis, along with difficulty engaging in conversation, make initial engagement more difficult. Self-determination theory and growing recovery literature point to the importance of maintaining a sense of community relatedness and connection, and developing a sense of agency and competence as important to active recovery and retention …

Business Faculty Publications and Presentations

Purpose The purpose of this paper is to explore the relationship between stress due to mistreatment by patients and caregivers’ own well-being indicators (anxiety, depression, and behavioral stress indicators). Based on predictions consistent with the job demands-resources model, it is anticipated that satisfaction with job resources would moderate the relationship between mistreatment by patients and well-being indicators. Design/methodology/approach Hypotheses were tested with a sample of 182 employees in a leading training and research university hospital in Istanbul, Turkey. Results were partially replicated for a separate sample of 122 healthcare workers. Data were collected using the survey methodology. Findings The findings …

Intensity Inhomogeneity Correction Of Sd-Oct Data Using Macular Flatspace, Andrew Lang, Aaron Carass, Bruno M. Jedynak, Sharon D. Solomon, Peter A. Calabresi, Jerry L. Prince

Mathematics and Statistics Faculty Publications and Presentations

Images of the retina acquired using optical coherence tomography (OCT) often suffer from intensity inhomogeneity problems that degrade both the quality of the images and the performance of automated algorithms utilized to measure structural changes. This intensity variation has many causes, including off-axis acquisition, signal attenuation, multi-frame averaging, and vignetting, making it difficult to correct the data in a fundamental way. This paper presents a method for inhomogeneity correction by acting to reduce the variability of intensities within each layer. In particular, the N3 algorithm, which is popular in neuroimage analysis, is adapted to work for OCT data. N3 works …

Facile Synthesis Of Ligand-Free Iridium Nanoparticles And Their In Vitro Biocompatibility, Anna L. Brown, Hayden Winter, Andrea M. Goforth, Gaurav Sahay, Conroy Sun

Chemistry Faculty Publications and Presentations

High-density inorganic nanoparticles have shown promise in medical applications that utilize radiation including X-ray imaging and as radiation dose enhancers for radiotherapy. We have developed an aqueous synthetic method to produce small (~ 2 nm) iridium nanoparticles (IrNPs) by reduction of iridium(III) chloride using a borohydride reducing agent. Unlike other solution-based synthesis methods, uniform and monodispersed IrNPs are produced without the use of surfactants or other solubilizing ligands. These nanoparticles are highly crystalline as observed by X-ray diffraction and high-resolution transmission electron microscopy (TEM). In vitro metabolic toxicity assays using hepatocyte and macrophage cells demonstrate that both IrNPs and iridium(III) …

OHSU-PSU School of Public Health Faculty Publications and Presentations

Adolescents in sub-Saharan Africa and in Botswana in particular continue to bear the brunt of the HIV epidemic. This analysis assessed gender differences among theory-based sexual and reproductive health protective and risk factors in a cross-sectional sample of 228 Batswana adolescents. Incongruence between preferred and actual sources of sexual information and several important gender differences in parent-adolescent relationships, psychosocial influences, and adolescent sexual behaviors were identified. Parents were the fourth most common source of information about sex; yet, over three-quarters of adolescents preferred to have parents teach them about sex. Boys reported more positive relationships with their parents and girls …

Effect Of Metformin Exposure On Growth And Photosynthetic Performance In The Unicellular Freshwater Chlorophyte, Chlorella Vulgaris, Brittany M. Cummings, Joseph A. Needoba, Tawnya D. Peterson

OHSU-PSU School of Public Health Faculty Publications and Presentations

Many pharmaceuticals have negative effects on biota when released into the environment. For example, recent work has shown that the commonly prescribed antidiabetic drug, metformin (N,N-dimethylbiguanide), has endocrine disrupting effects on fish. However, effects of metformin on aquatic primary producers are poorly known. We exposed cultured isolates of a freshwater chlorophyte, Chlorella vulgaris, to a range of metformin concentrations (0– 767.9 mg L-1) to test the hypothesis that exposure negatively affects photosynthesis and growth. A cessation of growth, increase in non-photochemical quenching (NPQ, NPQmax), and reduced electron transport rate (ETR) were observed 24 h after exposure to a metformin concentration …

Medicare Accountable Care Organizations Are Not Associated With Reductions In The Use Of Low-Value Coronary Revascularization, John M. Hollingsworth, Brahmajee K. Nallamothu, Phyllis Yan, Sarah Ward, Sunny C. Lin, Carrie H. Colla, Valerie A. Lewis, Multiple Additional Authors

OHSU-PSU School of Public Health Faculty Publications and Presentations

BACKGROUND:
Because specialty care accounts for half of Medicare expenditures, improving its value is critical to the success of Medicare accountable care organizations (ACOs) in curbing spending growth. However, whether ACOs have reduced low-value specialty care without compromising use of high-value services remains unknown.

METHODS AND RESULTS:
Using national Medicare data, we identified 2 cohorts: beneficiaries for whom the value of coronary revascularization is lower (those with ischemic heart disease without angina, congestive heart failure, or recent admission for acute myocardial infarction) and beneficiaries for whom its value is higher (those with recent acute myocardial infarction admission). We then determined …

Role Of Survey Response Rates On Valid Inference: An Application To Hiv Prevalence Estimates, Miguel Marino, Marcello Pagano

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background: Nationally-representative surveys suggest that females have a higher prevalence of HIV than males in most African countries. Unfortunately, these results are made on the basis of surveys with non-ignorable missing data. This study evaluates the impact that differential survey nonresponse rates between males and females can have on the point estimate of the HIV prevalence ratio of these two classifiers.
Methods: We study 29 Demographic and Health Surveys (DHS) from 2001 to 2010. Instead of employing often used multiple imputation models with a Missing at Random assumption that may not hold in this setting, we assess the effect of …

After a successful pilot study and randomized controlled trial, COMPASS was adapted for the Oregon Home Care Commission’s training system for statewide dissemination. The adapted program included fewer total meetings (7 versus 13), an accelerated meeting schedule (every two weeks versus monthly), and a range of …

Actual Vs. Perceived Hiv Testing Norms, And Personal Hiv Testing Uptake: A Cross-Sectional, Population-Based Study In Rural Uganda, Jessica M. Perkins, Viola N. Nyakato, Bernard Kakuhikire, Pamela K. Mbabazi, H. Wesley Perkins, Alexander C. Tsai, Sv Subramanian, Nicholas A. Christakis, David Bangsberg

OHSU-PSU School of Public Health Faculty Publications and Presentations

HIV testing is an essential part of treatment and prevention. Using population-based data from 1664 adults across eight villages in rural Uganda, we assessed individuals’ perception of the norm for HIV testing uptake in their village and compared it to the actual uptake norm. In addition, we examined how perception of the norm was associated with personal testing while adjusting for other factors. Although the majority of people had been tested for HIV across all villages, slightly more than half of men and women erroneously thought that the majority in their village had never been tested. They underestimated the prevalence …

Opposing Effects Of Impulsivity And Mindset On Sources Of Science Self- 5 Efficacy And Stem Interest In Adolescents, Lisa K. Marriott, Leigh A. Coppola, Suzanne H. Mitchell, Jana L. Bouwma-Gearhart, Zunqiu Chen, Dara Shifrer, Alicia Feryn, Jackilen S. Shannon

OHSU-PSU School of Public Health Faculty Publications and Presentations

Impulsivity has been linked to academic performance in the context of Attention Deficit Hyperactivity Disorder, though its influence on a wider spectrum of students remains largely unexplored, particularly in the context of STEM learning (i.e. science, technology, engineering, and math). STEM learning was hypothesized to be more challenging for impulsive students, since it requires the practice and repetition of tasks as well as concerted attention to task performance. Impulsivity was assessed in a cross-sectional sample of 2,476 students in grades 6-12. Results show impulsivity affects a larger population of students, not limited to students with learning disabilities. Impulsivity was associated …

The Relationship Between Hospital And Ehr Vendor Market Dynamics On Health Information Organization Presence And Participation, Sunny C. Lin, Julia Adler-Milstein

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background: Health Information Organizations (HIOs) are third party organizations that facilitate electronic health information exchange (HIE) between providers in a geographic area. Despite benefits from HIE, HIOs have struggled to form and subsequently gain broad provider participation. We sought to assess whether market-level hospital and EHR vendor dynamics are associated with presence and level of hospital participation in HIOs. Methods: 2014 data on 4523 hospitals and their EHR vendors were aggregated to the market level. We used multivariate OLS regression to analyze the relationship between hospital and vendor dynamics and (1) probability of HIO presence and (2) percent of hospitals …

Background

Approaches to screening for active tuberculosis (TB) among people living with HIV are inadequate, leading to missed diagnoses and poor implementation of preventive therapy.

Methods

Consecutive HIV-infected adults hospitalized at Mulago Hospital (Kampala, Uganda) between June 2011 and July 2013 with a cough ≥ 2 weeks were enrolled. Patients underwent extensive evaluation for pulmonary TB. Concentrations of 43 cytokines/chemokines were measured at the same time point as C-reactive protein (CRP) in banked plasma samples using commercially-available multiplex kits. Advanced classification algorithms were used to rank cytokines/chemokines for their ability to identify TB, and to model the specificity of the …
