The relationship of retinol binding protein 4 to changes in insulin resistance and cardiometabolic risk in overweight black adolescents.

Objective: To assess, among overweight non-hispanic black adolescents the relationship of changes in plasma retinol binding protein 4 (RBP4) over 3 years to changes in insulin resistance (IR) and 4 associated cardiometabolic risks.

Study Design: Nested, retrospective study of 51 overweight, post-pubertal non-Hispanic black participants in the Princeton School District Study. Participants were in the top (worsening IR) or bottom (improved IR) quartile for 3-year change in IR.

Impact of an environmental cleaning intervention on the presence of methicillin-resistant Staphylococcus aureus and vancomycin-resistant enterococci on surfaces in intensive care unit rooms.

Objectives: To evaluate the adequacy of discharge room cleaning and the impact of a cleaning intervention on the presence of methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE) on environmental surfaces in intensive care unit (ICU) rooms.

Design: Prospective environmental study.

Setting And Sample: Convenience sample of ICU rooms in an academic hospital.
