Comparative Assessment Of Methicillin Resistant Staphylococcus Aureus Diagnostic Assays For Use In Resource-Limited Settings, A. Ayebare, Lisa M. Bebell, Joel Bazira, S. Ttendo, V. Katawera, David Bangsberg, Mark J. Siedner, Multiple Additional Authors

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background: The rise of methicillin-resistant Staphylococcus aureus(MRSA) is a global health concern. Paucity of data on MRSA carriage prevalence and diagnostic methods in resource-limited settings hampers efforts to define the problem and plan an appropriate response. Additionally, high variability in cost and logistical characteristics of MRSA screening methods may impede infection control efforts. We compared the performance of locally-available chromogenic agar BD CHROMagar MRSA II and two PCR-based assays (Hain GenoQuick MRSA and Cepheid Xpert SA Complete) for the detection of asymptomatic MRSA carriage in nasal swabs.

Results: During 2015, we enrolled 500 patients from five hospital …

Portrayals Of Mental Illness, Treatment, And Relapse And Their Effects On The Stigma Of Mental Illness: Population-Based, Randomized Survey Experiment In Rural Uganda, Justin D. Rasmussen, Bernard Kakuhikire, C. Baguma, Scholastic Ashaba, Christine E. Cooper-Vince, Jessica M. Perkins, David Bangsberg, Alexander C. Tsai

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background

Mental illness stigma is a fundamental barrier to improving mental health worldwide, but little is known about how to durably reduce it. Understanding of mental illness as a treatable medical condition may influence stigmatizing beliefs, but available evidence to inform this hypothesis has been derived solely from high-income countries. We embedded a randomized survey experiment within a whole-population cohort study in rural southwestern Uganda to assess the extent to which portrayals of mental illness treatment effectiveness influence personal beliefs and perceived norms about mental illness and about persons with mental illness.

Methods and findings

Study participants were randomly assigned …

Words Matter: Putting An End To “Unsafe” And “Risky” Sex, Julia L. Marcus, Jonathan Snowden

OHSU-PSU School of Public Health Faculty Publications and Presentations

Change is constant in sexual health, as in health care more broadly. Novel pathogens are identified, epidemics emerge and reemerge, and new preventive and therapeutic agents are introduced and taken up by populations. On the other hand, some care strategies and practices fall by the wayside among clinicians and populations. Just as health and health care evolve, so too should the language that we use to describe them.

In this commentary, we express our concerns about the use of ambiguous and stigmatizing language when describing sexual behavior. A search on PubMed in September 2019 yielded over four thousand articles with …

Deep Learning Based Topology Guaranteed Surface And Mme Segmentation Of Multiple Sclerosis Subjects From Retinal Oct, Yufan He, Aaron Carass, Yihao Liu, Bruno Jedynak, Sharon D. Solomon, Shiv Saidha, Peter A. Calabresi, Jerry L. Prince

Mathematics and Statistics Faculty Publications and Presentations

Optical coherence tomography (OCT) is a noninvasive imaging modality that can be used to obtain depth images of the retina. Patients with multiple sclerosis (MS) have thinning retinal nerve fiber and ganglion cell layers, and approximately 5% of MS patients will develop microcystic macular edema (MME) within the retina. Segmentation of both the retinal layers and MME can provide important information to help monitor MS progression. Graph-based segmentation with machine learning preprocessing is the leading method for retinal layer segmentation, providing accurate surface delineations with the correct topological ordering. However, graph methods are time-consuming and they do not optimally incorporate …

Quality Of Life And Stigma Among People Living With Hiv/Aids In Iran, Mohammad Ebrahimi Kalan, Jian Han, Ziyad Ben Taleb, Kristopher P. Fennie, Mohammad Asghari Jafarabadi, Maryam Dastoorpoor, Nima Hajhashemi, Mitra Naseh, Shahnaz Rimaz

School of Social Work Faculty Publications and Presentations

Background: Stigma against HIV profoundly affects the quality of life (QOL) of people living with HIV/AIDS (PLWHA). We aimed to assess the factors associated with QOL in PLWHA in Iran, specifically HIV-related stigma, sociodemographic and clinical characteristics.

Methods: Two hundred PLWHA participated in this cross-sectional study. Data were collected using sociodemographic, stigma, and WHO-QOL-BREF questionnaires. Correlations, ANOVAs, and Student’s t-distribution tests were performed as bivariate analyses. We employed stepwise multiple linear regression analysis to explore the main factors associated with QOL domains.

Results: Six domains of QOL were negatively correlated with three domains of stigma (p < 0.001 for all). Stepwise multiple linear regression revealed that, after adjusting for con-founders, lack of healthcare insurance, having no basic knowledge of HIV/AIDs prior to diagnosis, low monthly income of participants and family, and stigma (blaming and distancing, discrimination, and fear) were associated with low mean score of different domains of QOL.

Workplace Incivility And Employee Sleep: The Role Of Rumination And Recovery Experiences, Caitlin A. Demsky, Charlotte Fritz, Leslie B. Hammer, Anne E. Black

Psychology Faculty Publications and Presentations

This study examines the role of negative work rumination and recovery experiences in explaining the association between workplace incivility and employee insomnia symptoms. Drawing on the perseverative cognition model of stress and the effort–recovery model, we hypothesize a moderated mediation model in which workplace incivility is associated with insomnia symptoms via negative work rumination. This indirect effect is proposed to be conditional on employees’ reported level of recovery experiences (i.e., psychological detachment from work and relaxation during nonwork time). In examining this model, we further establish a link between workplace incivility and sleep and identify one pathway to explain this …

Seasonal Patterns In Risk Factors For Taenia Solium Transmission: A Gps Tracking Study Of Pigs And Open Human Defecation In Northern Peru, Ian W. Pray, Claudio Muro, Ricardo Gamboa, Percy Vilchez, Wayne Wakeland, William Pan, William E. Lambert, Multiple Additional Authors

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background: Taenia solium (cysticercosis) is a parasitic cestode that is endemic in rural populations where open defecation is common and free-roaming pigs have access to human feces. The purpose of this study was to examine the roaming patterns of free-range pigs, and identify areas where T. solium transmission could occur via contact with human feces. We did this by using GPS trackers to log the movement of 108 pigs in three villages of northern Peru. Pigs were tracked for approximately six days each and tracking was repeated in the rainy and dry seasons. Maps of pig ranges were analyzed for …

Adapting An Elementary School Nutrition Context Assessment For High School Settings And Students, Deborah H. John, Beret Halverson, Tia H. Ho

Urban Studies and Planning Faculty Publications and Presentations

The school nutrition context is comprised of supportive environmental features, programs, policies, and social relationships that shape students’ healthy dietary choices and patterns. When engaging students as change agents, advocates, and partners in making healthy nutrition choices easier, environmental assessment tools developed for adults may be too complex or inappropriately tailored for youth. Adolescents need practical, user-tailored tools that reliably measure the food and beverage environments they encounter in school to inform youth-led changes to the school nutrition context. To meet this need, an evidence-based school environmental assessment was adapted for use in high schools by students as evaluators. Cooperative …

Equity In Starting Salaries: A Tangible Effort To Achieve Gender Equity In Medicine, Esther Choo, David R. Bangsberg

OHSU-PSU School of Public Health Faculty Publications and Presentations

Letter to the Editor.

In 2017, for the first time, more women than men enrolled in medical school, marking a pivotal moment for setting and achieving reasonable goals for gender equity in medicine.

Inequity in compensation is a key target: The gender pay gap begins upon first hire, is not explained by part-time work or choice of specialty, and compounds over time. In a 2016 Wall Street Journal analysis, female physicians earned only 64.5% of what male physicians earned, the largest disparity amongst the 446 occupations examined. In its 2018 compensation report, Doximity reported an average physician gender gap of …

Background: Hikikomori is a severe form of social withdrawal, originally described in Japan but recently reported in other countries. Debate exists as to what extent hikikomori is viewed as a problem outside of the Japanese context. Objective: We aimed to explore perceptions about hikikomori outside Japan by analyzing Western language content from the popular social media platform, Twitter. Methods: We conducted a mixed methods analysis of all publicly available tweets using the hashtag #hikikomori between February 1 and August 16, 2018, in 5 Western languages (Catalan, English, French, Italian, and Spanish). Tweets were first classified as to whether they described …

Relative Wealth, Subjective Social Status, And Their Associations With Depression: Cross-Sectional, Population-Based Study In Rural Uganda, Meghan L. Smith, Bernard Kakuhikire, C. Baguma, Justin D. Rasmussen, David Bangsberg, Multiple Additional Authors

OHSU-PSU School of Public Health Faculty Publications and Presentations

Depression is a leading cause of disability worldwide, and has been found to be a consistent correlate of socioeconomic status (SES). The relative deprivation hypothesis proposes that one mechanism linking SES to health involves social comparisons, suggesting that relative SES rather than absolute SES is of primary importance in determining health status. Using data from a whole-population sample of 1,620 participants residing in rural southwestern Uganda, we estimated the independent associations between objective and subjective relative wealth and probable depression, as measured by the depression subscale of the Hopkins Symptom Checklist (HSCLD). Objective relative wealth was measured by an asset …
