The aim of this study was to describe the revascularization process of autogenous bone block grafts placed with or without an expanded polytetrafluoroethylene (e-PTFE) membrane.', 'Thirty Wistar male rats had their mandibles augmented by either an autogenous bone block graft (group A) or an autogenous bone block graft covered with an e-PTFE membrane (group B). The animals were sacrificed by perfusion at baseline, 3, 7, 14, and 21 days after surgery.', 'After 3 days, the presence of vascular sprouts derived from the recipient bed was observed in group A; more discrete sprouts were also observed in group B. After 7 days, revascularization continued, with vessels derived from both the recipient bed and the surrounding connective tissue in group A but only from the recipient bed in group B. At 14 days, group A showed penetration of vessels at the periphery of the graft; the vessels reached varying distances inside it. In group B, revascularization of the graft occurred mainly near its perforation, its borders, and at the recipient bed-graft interface. After 21 days, graft vascular penetration could be observed throughout the extent of the graft in group A but only approximately halfway through the graft in group B.

To determine whether a paper-based antibiotic ordering system is an effective antibiotic stewardship measure.', 'An antibiotic order form (AOF) was introduced in July 2001 at a pediatric tertiary care hospital. Vancomycin courses prescribed before and after the AOF introduction were retrospectively reviewed based on Hospital Infection Control Practices Advisory Committee guidelines. The impact of the AOF on the appropriateness of vancomycin prescribing was evaluated in univariate and multivariable analyses that adjusted for other factors associated with appropriateness of vancomycin use. The density of vancomycin use after introduction of the AOF was also assessed.', 'Compliance with the AOF was poor (<50%) during the planned study period; therefore an additional 2 months of improved compliance (70-80%) were included. Rates of inappropriate vancomycin use increased during the study periods: 35% before AOF; 39% post-AOF; and 51% during the improved compliance period. On adjusted analysis, vancomycin utilization was significantly more inappropriate after introduction of the AOF. Vancomycin doses per 1000 patient days increased after introduction of the AOF.

Young adults are a population at great risk for problematic health behaviors. Alcohol mixed with energy drink (AmED) consumption is a relatively popular health risk behavior among young adults. AmED consumption continues to illustrate negative outcomes in the research literature, having been linked with other substance use, high-risk sexual behavior, and sexual victimization. Limited research to date has examined associations between AmED consumption and patterns of alcohol dependence.', 'Undergraduate college students (n=757) filled out an online survey which assessed their drinking habits in the past week and month, including their consumption of AmED beverages, personality characteristics, substance use, and problematic alcohol consumption via the Alcohol Use Disorders Identification Test (AUDIT).', 'A minority of participants reported AmED consumption in both the past month (11.6%) and past week (9.7%). Compared to their alcohol-only drinking counterparts, AmED consumers scored significantly higher on measures of impulsivity, and lower on anxiety sensitivity when compared to their alcohol-only drinking counterparts. In multivariate analyses, AmED consumption was robustly associated with patterns of alcohol dependence (AUDIT score≥8) among young adult college students, while controlling for energy drink use, alcohol use, personality factors, substance use, and demographic variables.
