Cardiometabolic Risk Assessments By Body Mass Index Z-Score Or Waist-To-Height Ratio In A Multiethnic Sample Of Sixth-Graders, Henry S. Kahn, Laure El Ghormli, Russell Jago, Gary D. Foster, Robert G. Mcmurray, John B. Buse, Diane D. Stadler, Roberto P. Trevino, Tom Baranowski, Healthy Study Group

GW Biostatistics Center

Convention defines pediatric adiposity by the body mass index -score (BMIz) referenced to normative growth charts. Waist-to-height ratio (WHtR) does not depend on sex-and-age references. In the HEALTHY Study enrollment sample, we compared BMIz with WHtR for ability to identify adverse cardiometabolic risk. Among 5,482 sixth-grade students from 42 middle schools, we estimated explanatory variations (R²) and standardized beta coefficients of BMIz or WHtR for cardiometabolic risk factors: insulin resistance (HOMA-IR), lipids, blood pressures, and glucose. For each risk outcome variable, we prepared adjusted regression models for four subpopulations stratified by sex and high versus lower fatness. …

METHODS: We conducted a survey of health care organizations in Washington, DC and Houston/Harris County to determine number of HIV tests completed in 2011, policy and practices associated with HIV testing, funding mechanisms, and reported barriers to testing in each jurisdiction and to compare results between jurisdictions.

RESULTS: In 2012, 43 Houston and 35 DC HIV-testing organizations participated in the survey. Participants represented 85% of Department of Health-supported testers in DC and 90% …

Review Of Hyperuricemia As New Marker For Metabolic Syndrome, Laura Billiet, Sarah Doaty, James D. Katz, Manuel T. Velasquez

Global Health Faculty Publications

Hyperuricemia has long been established as the major etiologic factor in gout. In recent years, a large body of evidence has accumulated that suggests that hyperuricemia may play a role in the development and pathogenesis of a number of metabolic, hemodynamic, and systemic pathologic diseases, including metabolic syndrome, hypertension, stroke, and atherosclerosis. A number of epidemiologic studies have linked hyperuricemia with each of these disorders. In some studies, therapies that lower uric acid may prevent or improve certain components of the metabolic syndrome. There is an association between uric acid and the development of systemic lupus erythematosus; the connection between …

Using A Theory Of Change Approach To Analyze Global Health Diplomacy Practice In Myanmar, Sangeeta Mookherji, Holly Greb, Rebecca Katz

Global Health Faculty Publications

The current picture of global health diplomacy (GHD) is one of increasing complexity, with multiple actors striving for multiple objectives, using a multitude of strategies and activities. Analysis and documentation of GHD practice is urgently needed to help identify the opportunities GHD provides for jointly improving global health and international relations, as well as possible unintended consequences. Systematic analysis of GHD practice is challenging without a conceptual framework. We identified a Theory of Change approach as one way to conceptualize GHD practice and potential impacts that could also depict its complexity and identify relationships and pathways for measuring success. We …

Developing A Dissemination Model To Improve Intervention Reach Among West Virginia Youth Smokers, Kimberly Horn, Traci Jarrett, Andrew Anesett-Rothermel, Nancy O'Hara Tompkins, Geri Dino

Prevention and Community Health Faculty Publications

The Not-On-Tobacco program is an evidence-based teen smoking cessation program adopted by the American Lung Association (ALA). Although widely disseminated nationally via ALA Master Trainers, in recent years, adoption and implementation of the N-O-T program in West Virginia has slowed. West Virginia, unfortunately, has one of the highest smoking rates in the US. Although it is a goal of public health science, dissemination of evidence-based interventions is woefully understudied. The present manuscript reviews a theoretical model of dissemination of the Not-On-Tobacco program in West Virginia. Based on social marketing, diffusion of innovations, and social cognitive theories, the nine-phase model incorporates …

Medicaid Reimbursement For Naloxone: A Toolkit For Advocates, Naomi Seiler, Katie B. Horton, Mary-Beth Malcarney

Health Policy and Management Faculty Publications

Naloxone is an opioid antagonist drug used to counter the effects of an opiate overdose. It can be administered in medical settings, such as an emergency room, or prescribed as a take‑home medication to be used in case of an emergency. Currently, most types of insurance will cover and reimburse for naloxone administered directly in a medical setting. However, coverage of prescription take‑home naloxone is limited. The Medicaid program provides health insurance for a large and growing number of Americans. Therefore, securing coverage for take‑home naloxone—including costs of counseling/training and for the medicine itself—within Medicaid should be a critical priority …

Global Health Faculty Publications

Background: Climate change is anticipated to influence heat-related mortality in the future. However, estimates of excess mortality attributable to future heat waves are subject to large uncertainties and have not been projected under the latest greenhouse gas emission scenarios.

Objectives: We estimated future heat wave mortality in the eastern United States (approximately 1,700 counties) under two Representative Concentration Pathways (RCPs) and investigated sources of uncertainty.

Methods: Using dynamically downscaled hourly temperature projections for 2057–2059, we projected heat wave days that were defined using four heat wave metrics and estimated the excess mortality attributable to them. We apportioned the sources of …

Synthesizing Data And Models For The Spread Of Mers-Cov, 2013: Key Role Of Index Cases And Hospital Transmission, Gerardo Chowell, Seth Blumberg, Lone Simonsen, Mark A. Miller, Cecile Viboud

Global Health Faculty Publications

The outbreak of Middle East respiratory syndrome coronavirus (MERS-CoV) has caused 209 deaths and 699 laboratory-confirmed cases in the Arabian Peninsula as of June 11, 2014. Preparedness efforts are hampered by considerable uncertainty about the nature and intensity of human-to-human transmission, with previous reproduction number estimates ranging from 0.4 to 1.5. Here we synthesize epidemiological data and transmission models for the MERS-CoV outbreak during April–October 2013 to resolve uncertainties in epidemic risk, while considering the impact of observation bias. We match the progression of MERS-CoV cases in 2013 to a dynamic transmission model that incorporates community and hospital compartments, and …

The Escherichia coli sequence type 131 (ST131) clone is notorious for extraintestinal infections, fluoroquinolone resistance, and extended-spectrum beta-lactamase (ESBL) production, attributable to a CTX-M-15-encoding mobile element. Here, we applied pulsed-field gel electrophoresis (PFGE) and whole-genome sequencing to reconstruct the evolutionary history of the ST131 clone. PFGE-based cluster analyses suggested that both fluoroquinolone resistance and ESBL production had been acquired by multiple ST131 sublineages through independent genetic events. In contrast, the more robust whole-genome-sequence-based phylogenomic analysis revealed that fluoroquinolone resistance was confined almost entirely to a single, rapidly expanding ST131 subclone, designated H30-R. Strikingly, 91% of the CTX-M-15-producing isolates also …

Strengthening Immigrants' Health Access: Current Opportunities, Leighton C. Ku

Health Policy and Management Issue Briefs

This brief summarizes key opportunities helping the nation’s newcomers in gaining health insurance coverage and health access that are possible under the current law. Provisions of the Affordable Care Act (ACA) will help millions of legal immigrants gain access to affordable health insurance coverage. At the same time, however, immigrants will also face new responsibilities. Like citizens, lawfully present immigrants will be responsible for having health insurance coverage or paying a tax penalty, although some are exempt. Rules about immigrants’ access to health insurance benefits are often complicated because they depend on specific immigration categories, as well as eligibility for …

Multiple Hypotheses Testing Procedures In Clinical Trials And Genomic Studies, Qing Pan

Epidemiology Faculty Publications

We review and compare multiple hypothesis testing procedures used in clinical trials and those in genomic studies. Clinical trials often employ global tests, which draw an overall conclusion for all the hypotheses, such as SUM test, Two-Step test, Approximate Likelihood Ratio test (ALRT), Intersection-Union Test (IUT), and MAX test. The SUM and Two-Step tests are most powerful under homogeneous treatment effects, while the ALRT and MAX test are robust in cases with non-homogeneous treatment effects. Furthermore, the ALRT is robust to unequal sample sizes in testing different hypotheses. In genomic studies, stepwise procedures are used to draw marker-specific conclusions and …

A Profile Of Community Health Center Patients: Implications For Policy, Peter Shin, Carmen Alvarez, Jessica Sharac, Sara J. Rosenbaum, Amanda Van Vleet, Julia Paradise, Rachel Garfield

Geiger Gibson/RCHN Community Health Foundation Research Collaborative

Community health centers are a key source of comprehensive primary care in medically underserved communities across the country, and their role is expected to grow as health coverage expands under the Affordable Care Act (ACA). To sharpen understanding of the health center patient population, this brief compares it to the overall low-income population, using data from the Health Center Patient Survey and the National Health Interview Survey,respectively. The pre-ACA profile of health center patients that emerges sets the stage for measuring change following implementation of the reform law and can inform health center policy, planning, and assessment moving forward.

Hospital Ships Adrift? Part 2: The Role Of U.S. Navy Hospital Ship Humanitarian Assistance Missions In Building Partnerships, Derek J. Licina, Sangeeta Mookherji, Gene Migliaccio, Cheryl Ringer

Global Health Faculty Publications

Introduction US Navy hospital ships are used as a foreign policy instrument to achieve various objectives that include building partnerships. Despite substantial resource investment by the Department of Defense (DoD) in these missions, their impact is unclear. The purpose of this study was to understand how and why hospital ship missions influence partnerships among the different participants.

Methods An embedded case study was used and included the hospital ship Mercy's mission to Timor-Leste in 2008 and 2010 with four units of analysis: the US government, partner nation, host nation, and nongovernmental organizations. Key stakeholders representing each unit were interviewed using …

Molecular Epidemiology Of Escherichia Coli Sequence Type 131 And Its H30 And H30-Rx Subclones Among Extended-Spectrum-Β-Lactamase-Positive And -Negative E. Coli Clinical Isolates From The Chicago Region, 2007 To 2010, Ritu Banerjee, Ari Robicsek, Michael A. Kusikowski, Stephen Porter, Brian D. Johnston, Evgeni Sokurenko, Veronika Tchesnokova, Lance B. Price, James R. Johnson

Environmental and Occupational Health Faculty Publications

We assessed Escherichia coli ST131 and its H30 and H30-Rx subclones for virulence genes, antimicrobial resistance, and extended-spectrum beta-lactamase (ESBL) type. Although both subclones were associated with ESBL production, H30-Rx isolates had higher resistance scores and were associated specifically with CTX-M-15. Three virulence genes (iha, sat, and iutA) were more prevalent among H30 than non-H30 ST131 isolates. Thus, the H30 and H30-Rx subclones are more antimicrobial resistant and have virulence profiles that are distinct from those of non-H30 ST131 isolates.

Targeting Inflammation Using Salsalate In Patients With Type 2 Diabetes: Effects On Flow-Mediated Dilation (Tinsal-Fmd)., Allison B Goldfine, J Stewart Buck, Cyrus Desouza, Vivian Fonseca, Yii-Der Ida Chen, Steven E Shoelson, Kathleen A. Jablonski, Mark A Creager, The Tinsal-Fmd Team

GW Biostatistics Center

OBJECTIVE: To test whether inhibiting inflammation with salsalate improves endothelial function in patients with type 2 diabetes (T2D).

RESEARCH DESIGN AND METHODS: We conducted an ancillary study to the National Institutes of Health-sponsored, multicenter, randomized, double-masked, placebo-controlled trial evaluating the safety and efficacy of salsalate in targeting inflammation to improve glycemia in patients with T2D.

Global Health Faculty Publications

Background

Assessing the mortality impact of the 2009 influenza A H1N1 virus (H1N1pdm09) is essential for optimizing public health responses to future pandemics. The World Health Organization reported 18,631 laboratory-confirmed pandemic deaths, but the total pandemic mortality burden was substantially higher. We estimated the 2009 pandemic mortality burden through statistical modeling of mortality data from multiple countries.

Methods and Findings

We obtained weekly virology and underlying cause-of-death mortality time series for 2005–2009 for 20 countries covering ~35% of the world population. We applied a multivariate linear regression model to estimate pandemic respiratory mortality in each collaborating country. We then used …

Innovations In Evaluating Health Campaigns In Developing Countries, W. Douglas Evans, Marc Boulay, Rebecca Firestone, Rajiv N. Rimal

GW Health Communication and Marketing Symposium Series

When conducting research in resource-poor settings, what research-method textbooks prescribe often varies substantially from what actually gets implemented on the ground. Randomization often breaks down, extraneous noise often pollutes the purity of experimental designs, and other challenges emerge in the field. The panel will highlight some of those challenges and engage the audience in discussions about possible solutions. Dr. Boulay will illustrate an analytic approach that combines propensity score matching and mediation analysis to provide a more comprehensive evaluation of SBCC activities. Dr. Firestone will discuss PSI's experience using coarsened exact matching to strengthen evaluation of its behavior change communications …

Medicaid Home- And Community-Based Services Programs Enacted By The Aca: Expanding Opportunities One Step At A Time, Carol O'Shaughnessy

National Health Policy Forum

The Patient Protection and Affordable Care Act of 2010 (ACA) enacted the most significant opportunities for optional state expansion of Medicaid-financed home- and community-based services (HCBS) since 1981, when Congress enacted the section 1915(c) waiver program. Three of the ACA provisions, the Balancing Incentive Program (BIP), the Community First Choice (CFC) state plan option, and the health home state plan option, offer states enhanced federal Medicaid matching funds as long as they meet federal requirements. The ACA also expanded two HCBS programs established under the Deficit Reduction Act of 2005 (DRA) by extending the Money Follows the Person (MFP) Rebalancing …

Staphylococcus aureus clonal complex 398 (CC398) isolates cluster into two distinct phylogenetic clades based on single-nucleotide polymorphisms (SNPs) revealing a basal human clade and a more derived livestock clade. The scn and tet(M) genes are strongly associated with the human and the livestock clade, respectively, due to loss and acquisition of mobile genetic elements. We present canonical single-nucleotide polymorphism (canSNP) assays that differentiate the two major host-associated S. aureus CC398 clades and a duplex PCR assay for detection of scn and tet(M). The canSNP assays correctly placed 88 S. aureusCC398 isolates from a reference collection into …

Seeking Value In Medicare: Performance Measurement For Clinical Professionals, Lisa Sprague

National Health Policy Forum

The Medicare program, despite its reputation of being a bill payer with little regard to the worth of the services it buys, has begun to put in place a range of programs aimed at assessing quality and value, with more to come. Attention to resource use and cost is nascent. The issues are complex, and it is no surprise that there is a level of contention between providers and regulators, even though both profess commitment to improved quality. This paper summarizes the quality and value programs that apply to physicians and other clinical professionals, as well as programs designed to …

Health Workforce Needs: Projections Complicated By Practice And Technology Changes, Rob Cunningham

National Health Policy Forum

As population growth and the aging of the overall population increase demand for health care, policymakers and analysts posit whether sufficient health care providers will be able to meet that demand. Some argue there are too few providers already; others say our current supply-demand problems lie with efficiency. But suppose both are correct? Perhaps the real challenge is to understand how physician practices are changing in response to market forces such as payment changes, provider distributions, and technology innovations. This issue brief reviews what is known about evolving practice organizations, professional mixes, information technology support, and the implications of these …
