Driving safety improves after individualized training: An RCT involving older drivers in an urban area

Objective: This study aimed to reproduce the results of a previous investigation on the safety benefits of individualized training for older drivers. We modified our method to address validity and generalizability issues. Methods: Older drivers were randomly assigned to one of the 3 arms: (1) education alone, (2) education + on road training, and (3) education + on road + simulator training. Older drivers were recruited from a larger urban community. At the pre- and posttests (separated by 4 to 8 weeks) participants followed driving directions using a Global Positioning System (GPS) navigation system. Results: Our findings support the positive influence of individualized on-road training for urban-dwelling older drivers. Overall, driving safety improved among drivers who received on-road training over those who were only exposed to an education session, F(1, 40) = 11.66, P = .001 (26% reduction in total unsafe driving actions [UDAs]). Statistically significant improvements were observed on observation UDAs (e.g., scanning at intersections, etc.), compliance UDAs (e.g., incomplete stop), and procedural UDAs (e.g., position in lane). Conclusion: This study adds to the growing evidence base in support of individualized older driver training to optimize older drivers' safety and promote continued safe driving.

Self sufficient wireless transmitter powered by foot-pumped urine operating wearable MFC

The first self-sufficient system, powered by a wearable energy generator based on microbial fuel cell (MFC) technology is introduced. MFCs made from compliant material were developed in the frame of a pair of socks, which was fed by urine via a manual gaiting pump. The simple and single loop cardiovascular fish circulatory system was used as the inspiration for the design of the manual pump. A wireless programmable communication module, engineered to operate within the range of the generated electricity, was employed, which opens a new avenue for research in the utilisation of waste products for powering portable as well as wearable electronics.

Report summary. Seniors' Falls in Canada: Second Report: key highlights

Injury in Canada is a serious public health concern. Injuries are a leading cause of hospitalization for children, young adults and seniors and a major cause of disability and death. Falls remain the leading cause of injury-related hospitalizations among Canadian seniors, and data from the Canadian Community Health Survey - Healthy Aging indicate that 20% of seniors living in the community reported a fall in the previous year, with a higher prevalence among older seniors, i.e., those aged over 80 years. Falls and associated outcomes not only harm the injured individuals but also affect their families, friends and care providers; they also place considerable pressure on the health care system. However, we do know that these personal and economic costs can be avoided through injury prevention activities. The Seniors' Falls in Canada: Second Report provides policy makers, researchers, community programmers and practitioners with current data and trends on falls, injuries and hospitalizations among Canadian adults aged 65 years and over. This report is intended for use in public health research, policy development and practice.
