Border Health Surveillance Mobile App Enhancements

COPH Research Area
Engaging the community and sustaining its investment in control programs is recommended as a critical component of assessing response during dengue outbreaks [1]. Evidence of the effectiveness of community engagement to impact entomological and to a lesser extent epidemiological endpoints is growing [2-5]. Both effectiveness and sustainability need to be explored as even effective programs may be unsustainable if community members lose motivation [6]. Evidence suggests that the use of theoretical frameworks such as the health belief model improves the effectiveness of public health interventions [7]. The health belief model would suggest that action is most likely taken when individuals have knowledge about Aedes mosquitoes and the viruses they carry; perceive Aedes mosquitoes to be a risk to them and their household members and that the risk is severe; perceive that the benefits of interventions outweigh the barriers to implementation; and are further motivated by self-efficacy and external cues to action such as media campaigns [8]. Indeed the best practices for communicating vector control strategies to the public have not been well defined particularly for industrialized countries where evaluation mosquito-borne disease messaging is particularly sparse. Vulnerable populations, including individuals residing in public housing, were less likely to receive information about dengue during an outbreak in Key West, FL [9]. During the West Nile outbreak in 2003 a study indicated people were most commonly getting their information from communications through newspapers, radio and TV broadcasts [10]however those that reported taking action were more likely to have gotten their information from the newspaper, word of mouth, or searching on the internet as compared to information they received from radio, TV, brochures, or health professionals perhaps due to the more active engagement associated with these sources. Some studies have indicated that mass media reports during outbreaks may not provide accurate risk information that could help individuals determine if they should take precautions [11, 12]. Leveraging mobile apps and social media as public health communication tools has become more broadly implemented for improving healthy behaviors; with most regular implementation addressing physical activity and smoking cessation [13, 14]. While mobile apps have shown variable effectiveness at increasing positive health behaviors, the potential is recognized [13].  Kidenga is a community-based surveillance and education app developed to address the increasing risk of Aedes-borne diseases in the southern United States. The Kidenga app was launched in late September 2016 and was developed through a collaborative partnership between the University of Arizona (lead institution) and CDC personnel based at the Division of Global Migration and Quarantine in San Diego, CA (www.kidenga.org). The intention of Kidenga is to both collect data on syndromes that may be consistent with Aedes-borne diseases and to provide timely and accurate risk information back to the user. As part of this work the Kidenga team will build upon existing Kidenga mobile application development to provide a “Spanish-version” for use along the Arizona and Texas borders to enhance surveillance and education for Zika, dengue and Chikungunya disease and their mosquito vector, Aedes aegypti (yellow fever mosquito). In addition, a preliminary assessment of the acceptability of Kidenga mobile application with end-user groups and a prioritization of modifications or enhancements to increase the usability and acceptability of Kidenga.

Polybrominated diphenyl ethers (PBDEs):  A series of PBDEs will be measured at trace levels (ng/g lipid weight) in breast milk provided by volunteers.  Breastmilk collection:  Participants will provide breastmilk samples (100 ml ideally) within chemically clean, 120 ml foil-wrapped glass jars, prepared by the University of Arizona (UA) or certified by the UA to be free of target chemicals within the sensitivity of the methods applied.  Several collection sessions may be required to fill each jar.  The samples will then be refrigerated and frozen when collection is completed (volume met).  Participants are advised to minimize skin contact with the jar (lip and lid) and to minimize the possibility of contamination by skin, hair, or dust.   Once received by the UA, samples will be stored at -20ºC until analysis. Polybrominated diphenyl ether analysis: The analytical approached follows methods successfully applied by the State of California and the US Centers for Disease Control and Prevention (CDC). The UA team is currently conducting research using Enhanced Matrix Removal (EMR) protocols that have been specifically developed to allow for lipid removal without loss of analyses and have been applied numerous times for analysis of trace organic chemicals in milk. In general, the EMR tubes contain a mixture of solid-phase extraction (SPE) sorbents and MgSO4, that will absorb the matrix material and excess water. Our team will only apply EMR upon successful performance evaluation that demonstrates equivalency, or better, to previously published work using the method Instrumental analysis will be performed using gas chromatography (GC) with mass spectrometric detection (GC-MS).  PBDEs will be separated using a DB-5MS column (15 m x 0.25 mm I.D. x 0.1um film thickness, Agilent J&W, USA).

Arizona’s Pesticide Use Registry and Vital Statistics Birth Certificates: A Rich Potential Resource for Studies of Associations Between Exposure to Pesticides and Health Outcomes among Farmworkers

Prenatal exposure to organophosphorus pesticides (OPs) has been associated with a wide range of adverse childhood outcomes [1]–[7]. However, most of these studies rely on OP biomarkers in the general population. These biomarkers disproportionately reflect non-toxic dietary ingestion of metabolites and cannot distinguish between parent pesticides. Exposure metrics that use agricultural pesticide applications may overcome these limitations, but such studies are limited to California. We propose to prepare Arizona’s Pesticide Use Registry as a resource for future studies of exposure to pesticides and childhood health outcomes, and to enhance exposure assessment by incorporating birth certificate-reported farmworker occupation into analyses. Farmworkers are at higher risk of pesticide-associated health risks due to occupational exposures, but farmworkers are difficult to identify and are highly transitory. Thus, we also propose a pilot study of prenatal exposure to OPs and preterm birth among farmworkers to assess the feasibility of this approach for future studies. The National Institute for Occupational Safety and Health and the University of California, Davis fund this project.

The Firefighter Multicenter Cancer Cohort Study: Framework Development and Testing

The purpose of this project is to develop and test a framework for establishing a long-term firefighter multicenter prospective cohort study focused on carcinogenic exposures and effects.  The specific aims are to: 1) Establish an oversight and planning board to provide study oversight, foster communication among fire organizations and help develop a long-term funding plan; 2) Create and test a cohort study data coordinating center and harmonized survey data protocols; 3) Develop and evaluate an exposure tracking system paired with quantitative exposure data to construct a firefighter carcinogen exposure matrix; and 4) Create a biomarker analysis center and evaluate the association between cumulative firefighter exposures and epigenetic effects. Relevance: Cancer is a leading cause of fire service morbidity and mortality, and a recent National Institute for Occupational Safety and Health (NIOSH) study demonstrated an excess mortality rate for cancer in firefighters compared with the general population (Daniels et al., 2014).  Firefighters are exposed to multiple carcinogens in the workplace through skin contamination and inhalation.  However, we currently do not understand which individual exposures are responsible for cancer in firefighters, the mechanisms by which these exposures cause cancer, or effective means of reducing exposures.  Since cancer has a long latency period, biomarkers are also needed that can measure the effects of carcinogen exposure well before the development of cancer, when interventions to prevent disease could be effective.  Development of a large (>10,000 firefighter) multicenter firefighter cancer prospective cohort study will address these needs, but the framework for such a study needs to be first developed and tested among a smaller initial set of fire service partners.  Methods: The study will build on recent and developing firefighter cancer prevention studies in Arizona, Florida and Massachusetts, adding volunteer and combination fire departments.  1) An Oversight and Planning Board will be established by the Fire Protection Research Foundation (FPRF) in association with the National Fallen Firefighter Foundation (NFFF) Fire Service Occupational Cancer Alliance (FSOCA) to provide oversight of the study through collaboration among fire service organizations, academia, and government agencies, and develop a long-term funding and sustainability plan.  2) A Data Coordination Center will design, develop and evaluate a framework for a multicenter prospective cohort study of firefighters and cancer risk, including standardized participant survey data collection tools and analysis protocols sufficient to address the short- and long-term study objectives as well as linkage with long-term outcome data including cancer development.  3) An Exposure Assessment Center will develop a carcinogen exposure matrix using information gleaned from self-reported and quantitative exposure measurements to provide improved occupational exposure data for comparison with epigenetic outcomes and eventual cancer outcomes.  Carcinogen exposures associated with specific fire types and job tasks will be evaluated across fire departments through exhaled breath monitoring and analysis of urine for absorbed contaminants, providing information to guide exposure reduction strategies.  4) The Biomarker Analysis Center will carry out pilot studies of epigenetic markers of cancer effect and cancer risk comparing firefighters with a range of cumulative exposures and non-firefighter controls.  For these purposes, blood and buccal cells will be collected during annual medical surveillance evaluations.  Anticipated outcomes: The proposed research will: establish the framework necessary for the subsequent development of a large multicenter cohort study of cancer in the fire service; advance our understanding of firefighter exposures to carcinogens; and help identify biomarkers of carcinogen effect and cancer risk.

Cancer Prevention in the Fire Service: Exposure Assessment, Toxic Effects and Risk Management

Purpose and Aims: The purpose of the proposed research is to identify effective methods of reducing firefighter exposure to carcinogens and associated toxic effects through completion of the following specific aims: 1) Evaluate exposure to carcinogens throughout the work shift; 2) Measure biomarkers of carcinogenic effect in relation to workplace exposures; and 3) Within a risk management framework, test the effectiveness of interventions to reduce fire service carcinogen exposure and effects. Relevance: Cancer is a leading cause of fire service morbidity and mortality.  Exposure to carcinogens occurs through skin contamination, through the lungs when respiratory protection is not worn during all phases of fire suppression and overhaul, and through inhalation during standby, operation of apparatus and off-gassing of equipment.  In addition to fire smoke, diesel exhaust exposure can occur from operation of apparatus at the fire ground and in the station.  Since cancer has a long latency period between exposure and disease onset, measurements are needed that can determine the effectiveness of new interventions on a much shorter time interval.  Methods: Exposure to particulates and volatile chemicals will be measured at the fireground and in-transit.  Diesel particulate matter monitoring during responses and in the fire station will also be completed.  Blood and urine collected during annual medical surveillance evaluations and post-fireground activities will be analyzed for chemical contaminants.  Biomarkers of carcinogenic effect will also be analyzed pre- and post-exposure, and evaluated for association with measured chemical contaminants.  The extent to which firefighter chemical exposures and biomarkers of effect can be reduced by following risk management steps will be determined.  Anticipated outcomes: The proposed research will identify carcinogenic exposures throughout the fire shift and measure the effectiveness of interventions designed to reduce cancer risks.

A Gender- and Culturally-Sensitive Weight Loss Intervention to Reduce Incidence of Non-Alcoholic Fatty Liver Disease in Hispanic Males

In the U.S., Hispanic males have the highest rate of overweight and obesity when compared to males of other racial/ethnic groups. Obesity contributes to the risk for certain cancers in Hispanics. For example, obesity is associated with non-alcoholic fatty liver disease (NAFLD), which is 1.4 and 1.9 times more common in Hispanics than in Non-Hispanic Whites (NHW) and African Americans, respectively. While not all individuals with NAFLD develop liver complications, nearly 30% will develop nonalcoholic steatohepatitis (NASH) and be at risk for hepatocellular carcinoma, the most common form of liver cancer in adults. Consequently, Hispanic males have the highest rates of liver cancer incidence in the U.S., twice those of NHW men. Weight loss is considered the first line of prevention for NAFLD progression. Yet, current research is lacking to inform best practices to engage Hispanic males in weight loss and/or to promote a successful weight loss trajectory. Without this information, the health disparities associated with obesity related cancer will continue to increase. Using existing practice guidelines and evidence from our qualitative assessments in overweight/obese Hispanic males, we will test a novel intervention approach to address this knowledge gap. We propose to 1) assess the feasibility, acceptability and preliminary efficacy of a gender- and culturally-sensitive weight loss intervention in 20 overweight/obese Hispanic males ages 18-64 over 24 weeks; and 2) examine pathologic changes in the liver (NAFLD, NASH, fibrosis, or cirrhosis) in 20 overweight/obese Hispanic males ages 18-64 over 24 weeks using a non-invasive Magnetic Resonance Imaging (MRI) of the liver. This project will be the first gender and culturally-sensitive weight loss intervention of which we are aware to explicitly target Hispanic males with an emphasis on reducing body weight. In addition, the intervention will provide highly impactful formative research on the effects of a weight loss lifestyle intervention on liver histology. Given the Hispanic population is the fastest growing in the U.S., efforts to identify strategies to promote weight control among Hispanic males has potential to significantly impact obesity-related cancer health disparities.

A New Hip Fracture Risk Prediction Tool Based on Common Predictors and Hip Geomer

COPH Research Area
Osteoporosis is a major public health problem. Women are at a particularly high risk for osteoporosis, and 50% of women age 50 or older may suffer from a fragility fracture in their remaining lifetime. Hip fractures are the most detrimental type of fractures. Research has been conducted to assess hip fracture risk so prevention methods could be used to reduce this risk in the growing number of older women. However, previous risk assessment approaches are limited to a few variables and linear combinations of these factors. Also, there is an increasing number of available measures, such as bone structures and skeletal muscle mass, and no reliable risk prediction model exists based on this wealth of information. The overall goal of this study is to develop a comprehensive and flexible model to assess the risk of hip fracture for a specific woman. There are three specific aims. The first aim is to generate a risk model, based on clinical data that accounts for the coupling effects of the factors involved in hip fracture. This research introduces a new approach in the field of hip fracture, Support Vector Machines (SVM), which explicitly identifies the configurations of factors that are likely to lead to hip fracture. The second aim is to refine the prediction/decision model from the first aim using both the SVM classifier and finite element modeling. A scheme has been developed to select, in a high dimensional space, data points that would improve the accuracy of the SVM-based risk prediction model. These data points would be evaluated (fracture or not) using a finite element model. The novelty of the proposed finite element model stems from its full parameterization so that the variability of the bone response can be studied with respect to variations (even small) of structural geometry and material parameters. The third aim is to validate and compare the SVM-based risk with and without the use of finite element analysis and develop a hip fracture risk calculator for the web. A cross-validation will be performed using data sets from the WHI as well as other cohorts. The flexibility of the SVM classification approach makes it easily deployable on the Internet. This study will be carried out using existing cohorts by an interdisciplinary team with experience in epidemiology of osteoporosis research, DXA measurements including hip structures and sarcopenia, fracture assessments, biostatistics approaches for large datasets, high dimensional analysis and finite element modeling, thus making this study highly feasible. The study results will have an extremely significant public health impact by providing an innovative tool for hip fracture risk assessments. This study will use innovative approaches, existing cohort resources, and interdisciplinary expertise to address a significant public health challenge: assessing the risk of hip fracture, the most detrimental type of fragility fractures. The study aims for a better risk assessment tool on the web that can be used by researchers and clinicians to assess an individual's hip fracture risk. This research will test new predictors and use the assumption free modeling approach to capture complex and non-linear relationships of predictors with fracture risk This study was funded by National Institute of Arthritis and Musculoskeletal and Skin Diseases of the National Institutes of Health.
