Rechargeable battery-powered bion microstimulators for neuromudulation

The rechargeable battery-powered bion microstimulator is designed to bring neurostimulation to mainstream medicine and improve the quality of life of those suffering from neurological disorders. The bion, through direct electrical stimulation of excitable tissues, is intended to treat numerous disorders including urinary urge incontinence, fecal incontinence, chronic headaches, peripheral pain, angina and obstructive sleep apnea. The rechargeable bion microstimulator, manufactured by Advanced Bionics Corporation, is designed to be implanted using a minimally invasive approach that would appeal to clinicians of different specialties as well as patients suffering from a wide variety of debilitating conditions. The bion is currently in clinical trials for the treatment of urinary urge incontinence and headaches. Other clinical trials are expected to follow in the future.

Factors affecting over-the-counter use of aspirin in the secondary prophylaxis of cardiovascular disease

Little is known about the contribution of over-the-counter (OTC) aspirin to cardiovascular prophylaxis. To investigate this, a two-phase cross-sectional study was carried out in nine general practices in North Staffordshire. In the first phase, all patients with cardiovascular disease (CVD) were identified from computer searches using morbidity registers and drug searches. The search also identfied the subgroup receiving prescribed prophylactic aspirin. In the second phase, a questionnaire was posted to all patients with CVD who were not on prescribed aspirin to establish their current use of OTC aspirin. Overall, 69% of the CVD group used aspirin, with 26% of aspirin being OTC. OTC aspirin use was more common in those aged under 65 years, men, and the more affluent. Also, there were significant differences in OTC aspirin use between the various practices. This study shows that a considerable amount of aspirin is used OTC in those with CVD. Its use is influenced by several factors that could be addressed when considering attempts to improve the overall uptake of aspirin.
