To increase student participation in the learning process, active learning methods, including small group learning, have become increasingly popular in modern curricula. One kind of small group learning, team-based learning, is a relatively new instructional strategy in health care education. Team-based learning uses theoretically based and empirically(More)
AIM This paper is a report of an evaluation of the psychometric properties of the Health Beliefs Related to Cardiovascular Disease Scale designed to measure beliefs related to cardiovascular disease risk and diet and exercise in adults with diabetes. BACKGROUND Heart attack and stroke are 2-4 times more common among adults with diabetes than those without(More)
Sensor networks have been a very active area of research in recent years. However, most of the sensors used in the development of these networks have been local and non-imaging sensors such as acoustics, seismic, vibration, temperature, humidity, etc. The development of emerging video sensor networks poses its own set of unique challenges, including high(More)
BACKGROUND With the aging population and improved cancer care, the number of cancer survivors is steadily increasing. Planning for their care requires an understanding of the impact of cancer and chronic conditions on quality of life. We sought to determine chronic conditions and health status in older cancer survivors compared to controls. METHODS In(More)

In this paper, we present swarm intelligence algorithms for pedestrian tracking. In particular, we present a modified Bacterial Foraging Optimization (BFO) algorithm and show that it outperforms PSO in a number of important metrics for pedestrian tracking. In our experiments, we show that BFO’s search strategy is inherently more efficient than PSO under a(More)
BACKGROUND Nausea and vomiting (N/V) during chemotherapy can have profound clinical and economic consequences. Effective antiemetic agents are available for prophylaxis, but barriers may prevent their use. For this population-based study, the authors assessed the rates of antiemetic prophylaxis use, and predictors of such use, among patients who were(More)
The goal of this study was to develop an algorithm for detecting epilepsy cases in managed care organizations (MCOs). A data set of potential epilepsy cases was constructed from an MCO's administrative data system for all health plan members continuously enrolled in the MCO for at least 1 year within the study period of July 1, 1996 through June 30, 1998.(More)
BACKGROUND Chronic obstructive pulmonary disease (COPD) and tobacco use are leading causes of morbidity and mortality. The prevalence and clinical impact of COPD on mortality and kidney transplantation among patients who begin dialysis therapy is unclear. METHODS We explored the clinical impact of COPD and continued tobacco use on overall mortality and(More)
PURPOSE The purpose of this study was to identify health disparities in children with non-CNS solid tumor malignancies and examine their impact on disease presentation and outcome. METHODS We examined the records of all children (age≤18years) diagnosed with a non-CNS solid tumor malignancy and enrolled in the Texas Cancer Registry between 1995 and 2009(More)
