The article offers information about stevia, a perennial shrub which serves as a natural and healthy alternative to sugar and artificial sweeteners. This herbal sweetener has sweet tasting glycosides, primarily Stevioside which help reduce postprandial blood glucose levels in type 2 diabetic patients. Studies on the general and reproductive toxicity of stevia demonstrates its safety profile at high dietary intake levels. Meanwhile, it has been approved by the U.S. Food and Drug Administration (FDA) as a dietary supplement or herb.

The article presents statistics on the percentage of adults over 25 years old who are suffering from serious psychological distress in the U.S.

Background: Key research priorities for surgical simulation have been identified in recent years. The aim of this study was to establish the progress that has been made within each research priority and what still remains to be achieved., Methods: Members of the Association for Surgical Education Simulation Committee conducted individualized literature reviews for each research priority that were brought together by an expert panel., Results: Excellent progress has been made in the assessment of individual and teamwork skills in simulation. The best methods of feedback and debriefing have not yet been established. Progress in answering more complex questions related to competence and transfer of training is slower than other questions. A link between simulation training and patient outcomes remains elusive., Conclusions: Progress has been made in skills assessment, curricula development, debriefing and decision making in surgery. The impact of simulation training on patient outcomes represents the focus of simulation research in the years to come., (Copyright © 2016 Elsevier Inc. All rights reserved.)
