The American Academy of Neurology recommends that individuals with a patent foramen ovale (PFO) who have had a stroke do not need routine catheter-based closure, due to limited evidence supporting its effectiveness. Instead, antiplatelet drugs such as aspirin are recommended to prevent blood clots.
A Pew Research Center survey found that a majority of Americans are worried about the potential use of gene editing, brain chip implants, and synthetic blood to 'enhance' human abilities. The survey reveals concerns about unequal access and moral acceptability, with more people expecting downsides than benefits.
Researchers at UBC and PSI developed a microneedle system that measures drug levels in patients' bloodstream without drawing blood. The system uses a tiny needle to collect a small sample of fluid beneath the skin, allowing for quick and easy monitoring of vancomycin levels.
A study by Japanese researchers found that watching TV for 2.5-4.9 hours daily increased pulmonary embolism deaths by 70%, with even more hours increasing the risk further. The risk is likely higher due to underreporting of deaths from this condition.
