Electric scooter related injuries in Calgary emergency departments.

Objectives: Electric scooters (e-scooters) have contributed to a rise in injury burden and emergency department (ED) utilization since their local introduction 3 years ago. This study is a novel collaboration between the City of Calgary's Department of Transportation and emergency medicine researchers to better understand the nature and frequencies of e-scooter injuries. It quantifies the incidence and characteristics of e-scooter related injuries treated in Calgary EDs/urgent care centres (UCCs).

Tempo-controlled resistance training of the hip abductors and ankle dorsiflexors with light loads does not improve postural sway in older adults.

The force steadiness capabilities of the hip abductors and ankle dorsiflexors can explain a significant amount of the variance in postural sway during four types of standing balance tests. Control over balance, as well as force steadiness, generally worsens with aging, although the latter can be improved with unique training interventions. The purpose of our study was to assess how tempo-controlled, light-load resistance training of the hip abductors and ankle dorsiflexors influences performance in clinical movement tests, postural sway, muscle strength, and force steadiness in older adults.

Hepatitis C Virus Screening of High-Risk Patients in a Canadian Emergency Department.

Background: Approximately 0.7% of the Canadian population is infected with hepatitis C virus (HCV), and many individuals are unaware of their infection. Our objectives were to utilize an emergency department (ED) based point-of-care (POC) HCV screening test to describe our local population and estimate the proportion of high-risk patients in our population with undiagnosed HCV.

Advantages of minimally invasive, balloon-dissector-assisted tissue expander placement: a clinical and experimental study.

Background: Tissue expansion has been dependent upon healing the access incision after placement. Delay can be reduced with minimally placed expanders. Smaller, remote incisions allow for earlier expansion.

Improving endothelial cell adhesion to vascular graft surfaces: clinical need and strategies.

Synthetic vascular grafts do not spontaneously endothelialize in humans and require some form of anticoagulation to maintain patency. Preseeding synthetic graft materials such as expanded polytetrafluoroethylene (ePTFE) and polyethylene terephthalate (PET) with endothelial cells (EC) has been examined in various in vitro and in vivo models. Although various studies provide encouraging results, clinical trials for EC seeding on synthetic grafts have not been equally successful.
