New estimation strategy improves soil carbon sampling in agricultural fields

Posted: 29 Mar 2022 07:00 AM PDT

Researchers have evaluated strategies for efficiently estimating soil organic carbon in agricultural fields. Quantifying soil organic carbon stocks in agricultural fields is essential for developing sustainable management practices and monitoring. The research team found that in a typical Midwestern agricultural field, public soil surveys and satellite imagery can be leveraged to efficiently select sample locations. This may reduce the number of samples needed to achieve a given precision (compared to random sampling).

I was here first! This is how hepatitis C inhibits hepatitis E

Posted: 29 Mar 2022 06:07 AM PDT

Infections with hepatitis C and E are so common that, going only by statistics, many people should be infected with both viruses at the same time. However, only very few such cases have been reported. A research team has a guess as to why this is the case: The researchers found that the viruses inhibit each other when they infect at the same time.

Critical and underutilized: Fire and police responders associated with higher cardiac arrest survival rates

Posted: 29 Mar 2022 06:07 AM PDT

Police and fire first responders are often first on the scene during an out-of-hospital cardiac arrest, and a new study finds that their intervention correlates with significantly higher chances of patient survival and hospital discharge with good neurological outcomes. Researchers say non-medical first responders are likely underutilized as lifesaving resources in these cases.

Rehabilitation psychologists: Specialists you may not yet know, but might one day need

Posted: 29 Mar 2022 06:07 AM PDT

Stroke treatments safe and effective for people with existing disability or dementia, study suggests

Posted: 28 Mar 2022 06:00 AM PDT

A research review found that clot-busting therapy and mechanical clot removal to treat ischemic stroke in people with a pre-existing disability or dementia was as safe and effective as in adults without those conditions. These treatments are key to preventing additional disability. A person's pre-existing disabilities or dementia may cloud the stroke assessment process, which may lead to clinicians thinking the stroke is more severe and beyond the window for optimal treatment. This often results in delayed treatment or no treatment. People with a disability or dementia should be included in randomized controlled trials for stroke treatment. Currently, evidence-based stroke treatment data and guidance for people with disability or dementia are extremely limited.
