Time Savings and Safety of EMS Administration of Antibiotics for Open Fractures.

Introduction: Early administration of antibiotics for open fractures reduces serious bone and soft tissue infections. The effectiveness of antibiotics in reducing these infections is time-dependent, with various surgical associations recommending administration within one hour of injury, or within one hour of patient arrival to the emergency department (ED). The extent to which prehospital antibiotic administration in these situations might reduce the time to treatment has not been previously reported.

A Flexible Antenna Array with Integrated Switching Matrix for Breast Cancer Detection.

In this report, we introduce a flexible board combining a custom switching circuit and 16 integrated antennas for a time-domain ultrawideband radar for breast health monitoring in one device. The goal of this study is to assess the suitability of the flexible prototype for tumor detection using carbon-polyurethane experimental breast models and comparing the performance to an earlier prototype with a rigid switching circuit and 16 separate antennas. The flexible antenna array allows direct contact with the patient skin while reducing the number of RF and DC cables needed in the previously reported system.
