An accelerometer, a wearable motion sensor on the hip or wrist, is becoming a popular tool in clinical and epidemiological studies for measuring the physical activity. Such data provide a series of activity counts at every minute or even more often and displays a person’s activity pattern throughout a day. Unfortunately, the collected data can…

Background.  The long-term and cumulative effect of multiple episodes of bacteremia and sepsis across multiple hospitalizations on the development of cardiovascular (CV) events is uncertain.

Warren. “Quantifying the Improvement in Sepsis Diagnosis, Documentation and Coding: the Marginal Causal Effect of Year of Hospitalization on Sepsis Diagnosis”. Annals of Epidemiology 26, no. 1 (2016): 71-76

Purpose To quantify the coinciding improvement in the clinical diagnosis of sepsis, its documentation in the electronic health records, and subsequent medical coding of sepsis for billing purposes in recent years. Methods We examined 98,267 hospitalizations in 66,208 patients who met systemic inflammatory response syndrome criteria at a tertiary care center from 2008 to 2012….

Benesh, Emily C., Jeff Gill, Laura E. Lamb, and Kelle H. Moley. “Maternal Obesity, Cage Density, and Age Contribute to Prostate Hyperplasia in Mice”. Reproductive Sciences 23, no. 2 (2016): 176-185

Identification of modifiable risk factors is gravely needed to prevent adverse prostate health outcomes. We previously developed a murine precancer model in which exposure to maternal obesity stimulated prostate hyperplasia in offspring. Here, we used generalized linear modeling to evaluate the influence of additional environmental covariates on prostate hyperplasia. As expected from our previous work,…

Background: The National Cancer Institute’s Transdisciplinary Research in Energetics and Cancer initiative is in its second round of funding. Despite increasing agreement that trans-disciplinary team-based research is valuable in addressing complex problems like energy balance and cancer, methods for constructing and maintaining transdisciplinary teams is lacking. Purpose: We articulate a method for assessing trans-disciplinary teams…

Traunmuller, Richard, Andreas Murr, and Jeff Gill. “Modeling Latent Information in Voting Data with Dirichlet Process Priors”. Political Analysis 23, no. 1 (2015): 1-20

We apply a specialized Bayesian method that helps us deal with the methodological challenge of unobservedheterogeneity among immigrant voters. Our approach is based on \emphgeneralized linear mixed Dirichlet models (GLMDM) whererandom effects are specified semiparametrically using a Dirichlet process mixture prior that has been shown to account forunobserved grouping in the data. Such models are…
