Single 30-day hospital readmission metric fails to reflect changing risk factors

A new study suggests that the standard 30-day hospital readmission metric fails to accurately reflect changing risk factors. Researchers found that early readmissions (0-7 days post discharge) were associated with acute illness markers, while late readmissions (8-30 days post discharge) were more closely tied to chronic illness burden.

Endurance athletes should be tested while exercising for potentially fatal heart condition

Current practice of testing athletes at rest may miss signs of right ventricular dysfunction that can lead to sudden death. A new study shows that exercise echocardiography can detect changes in the right ventricle's functioning during physical activity, providing a potential diagnostic tool for cardiologists managing athletes.

Psychology: Does aging affect decision making?

Older adults perform just as well as younger adults in simple decision-making, according to a study published in Cognition. However, in more complex decisions, older adults may struggle due to age-related cognitive decline. The study suggests that simple learning strategies can be useful for aging decision makers despite limitations.

Soil erosion contributes significantly to global carbon emissions

A new study reveals that soil erosion during rainy seasons contributes substantially to global carbon emissions. Organic carbon losses from soils account for approximately one-sixth of annual fossil fuel-induced carbon emissions, with the highest rates found in semi-arid soils.
