At least 55 cases of carbon monoxide poisoning came to Harborview Medical Center alone following the recent windstorm, highlighting the severe danger from using combustion-based sources of indoor heat. Local health officials urged the public not to use unvented, combustion-based sources of heat or power indoors, such as gas and kerosene heaters, charcoal briquettes or generators.
Clinical researchers at the University of Pennsylvania Health System are starting a trial utilizing a new mechanism to treat the heart when its electrical pulses essentially short-circuit, referred to as atrial fibrillation (A-Fib). The tool is a high intensity focused ultrasound (HIFU) ablation system. It’s the first to deliver energy bursts forward in a complete circle, all at once, from outside of the vein.
Could low-level heavy metal pollution be combining with warm water temperatures to fatally weaken sea life? A study examining the joint effects of cadmium and temperature on mitochondrial metabolism in oysters finds a combined effect that is potentially lethal and could be a significant contributor to recent oyster declines. The research has broad implications for cold-blooded marine organisms.
A new, easy-to-read booklet ? Stay Safe in Cold Weather! ? offers older adults tips on avoiding a dangerous condition called hypothermia. This free 12-page publication is now available from the National Institute on Aging (NIA), a part of the National Institutes of Health (NIH).
