Siedner, Data Santorino, Alexander J. Lankowski, Michael Kanyesigye, Mwebesa B. Bwana, Jessica E. Haberer, David R. Bangsberg

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background: Up to 50 % of HIV-infected persons in sub-Saharan Africa are lost from care between HIV diagnosis and antiretroviral therapy (ART) initiation. Structural barriers, including cost of transportation to clinic and poor communication systems, are major contributors.

Methods: We conducted a prospective, pragmatic, before-and-after clinical trial to evaluate a combination mobile health and transportation reimbursement intervention to improve care at a publicly operated HIV clinic in Uganda. Patients undergoing CD4 count testing were enrolled, and clinicians selected a result threshold that would prompt early return for ART initiation or further care. Participants enrolled in the pre-intervention period (January – …

Headaches are a common complaint for children presenting to the Emergency Department (ED) at Connecticut Children’s Medical Center (CCMC). Currently, there is little published regarding a standard treatment plan for pediatric headaches. The purpose of this study is to determine which medications are most commonly utilized and which are most effective in managing pediatric headaches. Differences in management of acute and chronic headaches in the ED at CCMC were examined. A retrospective chart review was conducted of all children who presented to the ED from January 1 to March 31, 2013 with a chief complaint or discharge diagnosis of “headache” …

Use Of The Robson Classification To Assess Caesarean Section Trends In 21 Countries: A Secondary Analysis Of Two Who Multicountry Surveys, Joshua P. Vogel, Ana Pilar Betrán, Nadia Vindevoghel, João Paulo Souza, Maria Regina Torloni, Jun Zhang, Özge Tunçalp, Rintaro Mori, Naho Morisaki, Eduardo Ortiz-Panozo, Bernardo Hernandez, Ricardo Pérez-Cuevas, Zahida Qureshi, A Metin Gülmezoglu, Marleen Temmerman

Obstetrics and Gynaecology, East Africa

Background: Rates of caesarean section surgery are rising worldwide, but the determinants of this increase, especially in low-income and middle-income countries, are controversial. In this study, we aimed to analyse the contribution of specific obstetric populations to changes in caesarean section rates, by using the Robson classification in two WHO multicountry surveys of deliveries in health-care facilities. The Robson system classifies all deliveries into one of ten groups on the basis of five parameters: obstetric history, onset of labour, fetal lie, number of neonates, and gestational age.

Methods: We studied deliveries in 287 facilities in 21 countries that …

Mesothelioma Patients With Germline Bap1 Mutations Have 7-Fold Improved Long-Term Survival, F. Baumann, E. Flores, A. Napolitano, S. Kanodia, E. Taioli, H. Pass, H. Yang, M. Carbone

Journal Articles

BRCA1-associated protein-1 (BAP1) mutations cause a new cancer syndrome, with a high rate of malignant mesothelioma (MM). Here, we tested the hypothesis that MM associated with germline BAP1 mutations has a better prognosis compared with sporadic MM. We compared survival among germline BAP1 mutation MM patients with that of all MM (N = 10 556) recorded in the United States Surveillance, Epidemiology, and End Results (SEER) data from 1973 to 2010. We identified 23 MM patients-11 alive-with germline BAP1 mutations and available data on survival. Ten patients had peritoneal MM, ten pleural MM and three MM in both locations. Thirteen …

The Glass Is Half Full: Evidence For Efficacy Of Alcohol-Wise At One University But Not The Other, K. Croom, L. Staiano-Coico, M. Lesser, D. K. Lewis, V. F. Reyna, T. C. Marchell, J. Frank, S. Ives

Journal Articles

This research extends the growing literature about online alcohol prevention programs for first-year college students. Two independent randomized control studies, conducted at separate universities, evaluated the short-term effectiveness of Alcohol-Wise, an online alcohol prevention program not previously studied. It was hypothesized the prevention program would increase alcohol knowledge and reduce alcohol consumption, including high-risk alcohol-related behaviors, among first-year college students. At both universities, the intervention significantly increased alcohol-related knowledge. At one university, the prevention program also significantly reduced alcohol consumption and high-risk drinking behaviors, such as playing drinking games, heavy drinking, and extreme ritualistic alcohol consumption. Implications for the use …

Tlr7 Influences Germinal Center Selection In Murine Sle, A. Boneparth, W. Huang, R. Bethunaickan, M. Woods, R. Sahu, S. Arora, M. Akerman, M. Lesser, A. Davidson

Journal Articles

TLR7 enhances germinal center maturation and migration of B cells to the dark zone where proliferation and somatic hypermutation occur. Our goal was to determine how Tlr7 dose influences selection of the autoreactive B cell repertoire in NZW/BXSB. Yaa mice bearing the site-directed heavy chain transgene 3H9 that encodes for the TLR7 regulated anti-CL response. To create a physiologic setting in which autoreactive B cells compete for survival with non-autoreactive B cells, we generated bone marrow chimeras in which disease onset occurred with similar kinetics and the transferred 3H9+ female non-Yaa, male Yaa or male TLR7(-/Yaa) cells could be easily …

Effectiveness Of Fecal-Derived Microbiota Transfer Using Orally Administered Capsules For Recurrent Clostridium Difficile Infection, B. E. Hirsch, N. Saraiya, K. Poeth, R. M. Schwartz, M. E. Epstein, G. Honig

Journal Articles

BACKGROUND: Clostridium difficile infection (CDI), a complication of antibiotic-induced injury to the gut microbiome, is a prevalent and dangerous cause of infectious diarrhea. Antimicrobial therapy for CDI is typically effective for acute symptoms, but up to one third of patients later experience recurrent CDI. Fecal-derived microbiota transplantation (FMT) can ameliorate the underlying dysbiosis and is highly effective for recurrent CDI. Traditional methods of FMT are limited by patient discomfort, risk and inefficient procedures. Many individuals with recurrent CDI have extensive comorbidities and advanced age. Widespread use of FMT requires strategies that are non-invasive, scalable and applicable across healthcare settings. METHODS: …

Seasonal Variations Of Complete Blood Count And Inflammatory Biomarkers In The Us Population - Analysis Of Nhanes Data, B. Liu, E. Taioli

Journal Articles

BACKGROUND: Recent studies reported seasonal differences in gene expression in white blood cells, adipose tissue, and inflammatory biomarkers of the immune system. There is no data on the seasonal variations of these biomarkers in the US general population of both children and adults. Then aim of this study is to explore the seasonal trends in complete blood count (CBC), and C-reactive protein (CRP) in a large non-institutionalized US population. METHODS: Seven cross-sectional data collected in the National Health and Nutrition Examination Survey (NHANES) during 1999-2012 were aggregated; participants reporting recent use of prescribed steroids, chemotherapy, immunomodulators and antibiotics were excluded. …

Determinants Of Survival In Malignant Pleural Mesothelioma: A Surveillance, Epidemiology, And End Results (Seer) Study Of 14,228 Patients, E. Taioli, A. S. Wolf, M. Camacho-Rivera, A. Kaufman, D. S. Lee, D. Nicastri, K. Rosenzweig, R. M. Flores

Journal Articles

INTRODUCTION: Left untreated, malignant pleural mesothelioma (MPM) is associated with uniformly poor prognosis. Better survival has been reported with surgery-based multimodality therapy, but to date, no trial has demonstrated survival benefit of surgery over other therapies. We evaluated whether cancer-directed surgery influenced survival independently from other predictors in a large population-based dataset. METHODS: The SEER database was explored from 1973 to 2009 to identify all cases of pathologically-proven MPM. Age, sex, race, year of diagnosis, histology stage, cancer-directed surgery, radiation, and vital status were analyzed. The association between prognostic factors and survival was estimated using Cox regression and propensity matched …

Frequency Of Surgery In Black Patients With Malignant Pleural Mesothelioma, E. Taioli, A. S. Wolf, J. Moline, M. Camacho-Rivera, R. M. Flores

Journal Articles

Introduction. Malignant Pleural Mesothelioma (MPM) is a rare disease, even less frequently described in minority patients. We used a large population-based dataset to study the role of race in MPM presentation, treatment, and survival. Methods. All cases of pathologically proven MPM were identified in the Surveillance, Epidemiology, and End Results (SEER) database. Age, sex, diagnosis year, stage, cancer-directed surgery, radiation, and vital status were analyzed according to self-reported race (black or white). Results. There were 13,046 white and 688 black MPM patients (incidence: 1.1 per 100,000 whites; 0.5 per 100,000 blacks; age-adjusted,P = 0.01). Black patients were more likely to …

Breast Cancer Risk In Metabolically Healthy But Overweight Postmenopausal Women, M. J. Gunter, X. Xie, X. Xue, G. C. Kabat, T. E. Rohan, S. Wassertheil-Smoller, G. Y. Ho, J. Wylie-Rosett, J. Beasley, H. D. Strickler, +2 Additional Authors

Journal Articles

Adiposity is an established risk factor for postmenopausal breast cancer. Recent data suggest that high insulin levels in overweight women may play a major role in this relationship, due to insulin's mitogenic/antiapoptotic activity. However, whether overweight women who are metabolically healthy (i.e., normal insulin sensitivity) have elevated risk of breast cancer is unknown. We investigated whether overweight women with normal insulin sensitivity [i.e., homeostasis model assessment of insulin resistance (HOMA-IR) index, or fasting insulin level, within the lowest quartile (q1)] have increased breast cancer risk. Subjects were incident breast cancer cases (N = 497) and a subcohort (N = 2,830) …

Differential Expression Of Circulating Micrornas According To Severity Of Colorectal Neoplasia, G. Y. Ho, H. J. Jung, R. E. Schoen, T. Wang, J. Lin, Z. Williams, J. L. Weissfeld, J. Y. Park, O. Loudig, Y. Suh

Journal Articles

There is a need to develop a colorectal cancer (CRC) screening test that is noninvasive, cost effective, and sensitive enough to detect preneoplastic lesions. This case-control study examined the feasibility of using circulating extracellular microRNAs (miRNAs) to differentiate a spectrum of colorectal neoplasia of various severity and hence for early detection of colorectal neoplasia. Archived serum samples of 10 normal controls and 31 cases, including 10 with nonadvanced adenoma, 10 with advanced adenoma, and 11 with CRC, were profiled for circulating miRNAs using next-generation sequencing. Multiple linear regression, adjusting for age, gender, and smoking status, compared controls and the 3 …

Oral Bisphosphonate Use And Risk Of Postmenopausal Endometrial Cancer, P. A. Newcomb, M. N. Passarelli, A. I. Phipps, G. L. Anderson, J. Wactawski-Wende, G. Y. Ho, M. J. O'Sullivan, R. T. Chlebowski

Journal Articles

PURPOSE: Bisphosphonates are common medications used for the treatment of osteoporosis and are also used to reduce metastases to bone in patients with cancer. Several studies, including the Women's Health Initiative (WHI), have found that use of bisphosphonates is associated with reduced risk of developing breast cancer, but less is known about associations with other common malignancies. This study was aimed at examining the effects of bisphosphonates on the risk of endometrial cancer. METHODS: We evaluated the relationship between use of oral bisphosphonates and endometrial cancer risk in a cohort of 89,918 postmenopausal women participating in the WHI. A detailed …

Ebola Scare And Measles Resurgence: Mandatory Isolation/Quarantine And Vaccination, Mark C. Aita Md, Takeem T. Ragland Ma

Journal of Health Ethics

Public outcry for radical isolation and quarantine policies followed the first Ebola diagnosis in the United States when Eric Duncan, upon his return home Oct 2014 from West Africa, then in the midst of a catastrophic Ebola epidemic, tested positive for Ebola. Likewise, the Dec 2014 Disneyland measles outbreak unleashed an angry backlash against parents who refused to have their children vaccinated; and there was public momentum to repeal all legal exemptions to mandatory vaccination of school children. This paper presents an ethical and legal analysis to adjudicate the issue which is at stake in both controversies; namely the inherent …

Factors Associated With High Rates Of Antiretroviral Medication Adherence Among Youth Living With Perinatal Hiv In Thailand, Ezer Kang

Department of Psychology Faculty Publications

 Antiretroviral medication adherence behaviour among Thai youth with perinatal HIV in Thailand has received growingattention. However, few studies have examined individual predictors of antiretroviral adherence using multipleself-reports. A convenience sample of 89 Thai youth (interquartile range 14–16 years) with perinatal HIV at threepaediatric programmes in Chiang Mai completed a structured questionnaire and reported their antiretroviral adherencein the past one, seven and 30 days using count-based recall and a visual analog scale. Mean self-reported adherencerates ranged from 83.5% (past 30 days) to 99.8% (yesterday) of the time. One-inflated beta regression models were usedto examine the associations between antiretroviral adherence outcomes, treatment …
