Reducing fine particulate matter concentrations could lead to significant improvements in cognitive performance, equivalent to a shift from median to 63rd percentile scores.
Researchers have identified a gene variant linked to chronic pain after traumatic injury, specifically the FKBP5 gene, which regulates the stress response and is affected by microRNA miR-320a. Individuals with this variant are more likely to experience increased pain due to altered cortisol levels and nerve sensitization.

The coordinated care improved patients' understanding of their disease, treatment side-effects, and overall strength in fighting cancer.
A recent study found that major disruptive events, such as clinician losses and changes in ownership, frequently disrupt primary care practices in Oklahoma. These events negatively affect quality improvement efforts and patient care, highlighting the need for further research to address their root causes.
Chronic sleep deprivation increases risk of motor vehicle crashes due to impaired cognitive function. The study found severe sleep apnea is associated with a 123% increased risk, while mild to moderate sleep apnea elevates the risk by 13%. Short sleep duration also contributes to crash risks.
