Potentially inappropriate medications still pose challenge in nursing home

A recent study found that 44% of nursing home residents with dementia were taking PIMs at admission, and many stopped or started these medications during their stay. The researchers suggest a person-centered approach to discontinuing PIMs, especially for frail older adults.

New technique offers clues to measure the deoxygenation of the ocean

Scientists developed a method to quantify past oxygen depletion in oceans using thallium isotope composition of ancient seafloor sediments. The analysis suggests up to half of the deep ocean was oxygen-depleted during Oceanic Anoxic Event 2, with modern trends showing similar rates of deoxygenation.
