Driving Habits and Reaction Times on a Driving Simulation in Older Drivers With Chronic Heart Failure.

Background: Judgement and reaction times during complex tasks like driving may be impaired in older adults with chronic heart failure (HF). This study sought to report the driving habits and reaction times of older patients with HF in a specially designed urban driving simulation.

Methods And Results: We conducted a prospective observational study in HF patients and controls.

Randomised controlled trial of video clips and interactive games to improve vision in children with amblyopia using the I-BiT system.

Background: Traditional treatment of amblyopia involves either wearing a patch or atropine penalisation of the better eye. A new treatment is being developed on the basis of virtual reality technology allowing either DVD footage or computer games which present a common background to both eyes and the foreground, containing the imagery of interest, only to the amblyopic eye.

Methods: A randomised control trial was performed on patients with amblyopia aged 4-8 years with three arms.

Systemic arterial pressure wave reflections during acute hemorrhage.

Objective: To determine the effects of hemorrhage on wave-reflection-induced systolic pressure augmentation in the aorta.

Design: Randomized, controlled laboratory experiment.

Setting: University research laboratory.
