Reduction of High School Ice Hockey Injuries With Implementation of New Checking/Boarding Rules.

Objective: Evaluate whether rule changes by the National Federation of State High School Associations (NFHS) were associated with reduced injury rates in US high school ice hockey players.

Design: We compared injury rates for the 3 seasons before the rule changes (2011-2012, 2012-2013, and 2013-2014) with the 2 subsequent seasons (2014-2015 and 2015-2016) using data from the High School Reporting Information Online (RIO) database.

Setting: Convenience sample of US high schools.

A nationwide survey of antimicrobial stewardship practices.

Objective: The goal of this study was to characterize hospital antimicrobial stewardship practices nationwide and to identify factors associated with the presence of these programs.

Methods: The first web-based survey was sent in 2009 to members of the Yankee Alliance and the Premier Healthcare Alliance, nationwide organizations of health-care providers. The second survey, a slightly modified version of the first, was sent in 2010 to a commercially purchased list of hospital pharmacy director e-mail addresses.

Evaluation of programmatic changes to an antimicrobial stewardship program with house officer feedback.

Rationale, Aims And Objectives: A collegial relationship between prescribers and antimicrobial stewards, along with an appreciation of the importance of antimicrobial stewardship, is essential for optimal functioning of an antimicrobial stewardship program (ASP). Programmatic adjustments based on feedback may be beneficial to the success of ASPs. The objective of this study is to assess the experience of house officers with the ASP and the effect of programmatic improvements.

Nanoscale control of silica particle formation via silk-silica fusion proteins for bone regeneration.

The biomimetic design of silk/silica fusion proteins was carried out, combining the self assembling domains of spider dragline silk (Nephila clavipes) and silaffin derived R5 peptide of Cylindrotheca fusiformis that is responsible for silica mineralization. Genetic engineering was used to generate the protein-based biomaterials incorporating the physical properties of both components. With genetic control over the nanodomain sizes and chemistry, as well as modification of synthetic conditions for silica formation, controlled mineralized silk films with different silica morphologies and distributions were successfully generated; generating 3D porous networks, clustered silica nanoparticles (SNPs), or single SNPs.

Expert clinical assessment of thorax stiffness of infants and children during chest compressions.

Background: High-fidelity manikins have been shown to be useful in teaching appropriate cardiopulmonary resuscitation (CPR) techniques. Similarity of manikin chest compression characteristics to real children is desirable. Little data exists on thorax stiffness in infants and children to guide manikin construction.
