Evaluating the economic effects of genomic sequencing of pathogens to prioritise hospital patients competing for isolation beds.

Objective This study compared the costs and patient movements of a new hospital protocol to discontinue contact precautions for patients with non-multiresistant methicillin-resistant Staphylococcus aureus (nmMRSA), based on whole-genome sequencing (WGS) of pathogens with current practice. Methods A hybrid simulation model was constructed and analysed over a 12-month time horizon. Six multidrug-resistant organisms and influenza were modelled concurrently where infected patients competed for isolation beds.

Improving large class performance and engagement through student-generated question banks.

Disciplines such as Biochemistry and Molecular Biology, which involve concepts not included in the high-school curriculum, are very challenging for many first year university students. These subjects are particularly difficult for students accustomed to surface learning strategies involving memorization and recall of facts, as a deeper understanding of the relationship between concepts is needed for successful transfer to related areas and subsequent study. In this article, we explore an activity in a very large first year Molecular Biology course, in which students create multiple-choice questions related to targeted learning outcomes, and then answer and evaluate one another's questions.

CAN DO Houston: a community-based approach to preventing childhood obesity.

Background: Comprehensive, community-based efforts may reduce rates of childhood obesity.

Community Context: Almost half of the children in Houston are overweight or obese, even though Houston has many available resources that support good nutrition, physical activity, and prevention of weight gain among children.

Methods: We used existing resources to implement a community-based, childhood obesity prevention initiative in 2 low-income neighborhoods in Houston.
