A Case-Control Study Of Physical Activity Patterns And Risk Of Non-Fatal Myocardial Infarction, Jian Gong, Hannia Campos, Mark Fiecas, Stephen Mcgarvey, Robert Goldberg, Caroline Richardson, Ana Baylin Dec 2012

A Case-Control Study Of Physical Activity Patterns And Risk Of Non-Fatal Myocardial Infarction, Jian Gong, Hannia Campos, Mark Fiecas, Stephen Mcgarvey, Robert Goldberg, Caroline Richardson, Ana Baylin

Mark Fiecas

Background The interactive effects of different types of physical activity on cardiovascular disease (CVD) risk have not been fully considered in previous studies. We aimed to identify physical activity patterns that take into account combinations of physical activities and examine the association between derived physical activity patterns and risk of acute myocardial infarction (AMI). Methods We examined the relationship between physical activity patterns, identified by principal component analysis (PCA), and AMI risk in a case-control study of myocardial infarction in Costa Rica (N=4172), 1994-2004. The component scores derived from PCA and total METS were used in natural cubic spline models …

Cross-Sectional Hiv Incidence Estimation In Hiv Prevention Research, Ron Brookmeyer, Oliver Laeyendecker, Deborah Donnell, Susan H. Eshleman Dec 2012

Cross-Sectional Hiv Incidence Estimation In Hiv Prevention Research, Ron Brookmeyer, Oliver Laeyendecker, Deborah Donnell, Susan H. Eshleman

Ron Brookmeyer

Accurate methods for estimating HIV incidence from cross-sectional samples would have great utility in prevention research. This report describes recent improvements in cross-sectional methods that significantly improve their accuracy. These improvements are based on the use of multiple biomarkers to identify recent HIV infections. These multiassay algorithms (MAAs) use assays in a hierarchical approach for testing that minimizes the effort and cost of incidence estimation. These MAAs do not require mathematical adjustments for accurate estimation of the incidence rates in study populations in the year before sample collection. MAAs provide a practical, accurate, and cost-effective approach for cross-sectional HIV incidence …

Intellectual Property And Public Health – A White Paper, Ryan G. Vacca, Jim Chen, Jay Dratler Jr., Tom Folsom, Timothy Hall, Yaniv Heled, Frank Pasquale, Elizabeth Reilly, Jeff Samuels, Kathy Strandburg, Kara Swanson, Andrew Torrance, Katharine Van Tassel Dec 2012

Intellectual Property And Public Health – A White Paper, Ryan G. Vacca, Jim Chen, Jay Dratler Jr., Tom Folsom, Timothy Hall, Yaniv Heled, Frank Pasquale, Elizabeth Reilly, Jeff Samuels, Kathy Strandburg, Kara Swanson, Andrew Torrance, Katharine Van Tassel

Katharine Van Tassel

On October 26, 2012, the University of Akron School of Law’s Center for Intellectual Property and Technology hosted its Sixth Annual IP Scholars Forum. In attendance were thirteen legal scholars with expertise and an interest in IP and public health who met to discuss problems and potential solutions at the intersection of these fields. This report summarizes this discussion by describing the problems raised, areas of agreement and disagreement between the participants, suggestions and solutions made by participants and the subsequent evaluations of these suggestions and solutions.

Led by the moderator, participants at the Forum focused generally on three broad …

Mobility, Latino Migrants, And The Geography Of Sex Work: Using Ethnography In Public Health Assessments, Thurka Sangaramoorthy, Karen Kroeger Dec 2012

Mobility, Latino Migrants, And The Geography Of Sex Work: Using Ethnography In Public Health Assessments, Thurka Sangaramoorthy, Karen Kroeger

Thurka Sangaramoorthy

Recent studies have documented frequent use of female sex workers among Latino migrant men in the southeastern United States, yet little is known about the context in which sex work takes place or the women who provide these services. As anthropologists working in applied public health, we use rapid ethnographic assessment as a technical assistance tool to document local understandings of the organization and typology of sex work and patterns of mobility among sex workers and their Latino migrant clients. By incorporating ethnographic methods in traditional public health needs assessments, we were able to highlight the diversity of migrant experiences …

Progression From New Methicillin-Resistant Staphylococcus Aureus Colonisation To Infection: An Observational Study In A Hospital Cohort, Michelle Nd Balm, Andrew A. Lover, Sharon Salmon, Paul A. Tambyah, Dale A. Fisher Dec 2012

Progression From New Methicillin-Resistant Staphylococcus Aureus Colonisation To Infection: An Observational Study In A Hospital Cohort, Michelle Nd Balm, Andrew A. Lover, Sharon Salmon, Paul A. Tambyah, Dale A. Fisher

Andrew Lover

Background
Patients newly colonised with methicillin-resistant Staphylococcus aureus (MRSA) are at higher risk of clinical MRSA infection. At present, there are limited data on the duration or magnitude of this risk in a hospital population with a known time of MRSA acquisition.
Methods
A retrospective cohort study of 909 adult patients known to have newly identified MRSA colonisation during admission to National University Hospital, Singapore between 1 July 2007 and 30 June 2011 was undertaken. Patients were excluded if they had history of previous MRSA colonisation or infection, or if they had been a hospital inpatient in the preceding 12 …

Quantifying Effect Of Geographic Location On Epidemiology Of Plasmodium Vivax Malaria, Andrew A. Lover, Richard J. Coker Dec 2012

Quantifying Effect Of Geographic Location On Epidemiology Of Plasmodium Vivax Malaria, Andrew A. Lover, Richard J. Coker

Andrew Lover

Recent autochthonous transmission of Plasmodium vivax malaria in previously malaria-free temperate regions has generated renewed interest in the epidemiology of this disease. Accurate estimates of the incubation period and time to relapse are required for effective malaria surveillance; however, this information is currently lacking. By using historical data from experimental human infections with diverse P. vivax strains, survival analysis models were used to obtain quantitative estimates of the incubation period and time to first relapse for P. vivax malaria in broad geographic regions. Results show that Eurasian strains from temperate regions have longer incubation periods, and Western Hemisphere strains from …

Methods For Evaluating Prediction Performance Of Biomarkers And Tests, Margaret S. Pepe Phd, Holly Janes Phd Dec 2012

Methods For Evaluating Prediction Performance Of Biomarkers And Tests, Margaret S. Pepe Phd, Holly Janes Phd

Margaret S Pepe PhD

This chapter describes and critiques methods for evaluating the performance of markers to predict risk of a current or future clinical outcome. We consider three criteria that are important for evaluating a risk model: calibration, benefit for decision making and accurate classification. We also describe and discuss a variety of summary measures in common use for quantifying predictive information such as the area under the ROC curve and R-squared. The roles and problems with recently proposed risk reclassification approaches are discussed in detail.
