Immune response may link social rejection to later health outcomes

A new study published in Clinical Psychological Science found that recent exposure to targeted rejection activates inflammatory signaling pathways and elevates pro-inflammatory signaling molecules. Participants with higher perceived social status showed a more pronounced effect, suggesting an adaptive response in top-tier individuals.

Endoscopic mucosal resection before radiofrequency ablation is equally effective compared with RFA alone for advanced Barrett's esophagus

A new study found that EMR before RFA is a safe and effective treatment option for patients with nodular Barrett's esophagus and advanced neoplasia. The performance of EMR before RFA was not associated with a diminished likelihood of success or increased stricture rate compared to RFA alone.

Link between creativity and mental illness confirmed

Researchers found that people in creative professions are treated more often for mental illness than the general population, particularly for schizophrenia. Creative fields were also associated with higher rates of bipolar disorder, depression, anxiety syndrome, substance abuse, and suicidal behavior.

Patient-reported outcomes essential to comparative effectiveness research

A research group recommends that patient-reported symptoms and health-related quality of life measures should be assessed in comparative effectiveness studies. This approach is crucial for adequate evaluation of cancer treatments, as patients' experiences directly impact their ability to function and maintain quality of life.

Great apes, small numbers

A genetic study has found that Sumatran orangutans have undergone a substantial recent population decline due to deforestation. However, the research also identified critical corridors for dispersal migrations that can help maintain genetic diversity and aid in the species' conservation if protected.

Exposure to 'Prestige' fuel causes short-term damage to rat DNA

A new study on rats exposed to fuel similar to that of the Prestige tanker oil spill shows a direct link between respiratory exposure to compounds discharged by the fuel and damage to genetic material. The research suggests that people who carry out industrial cleaning of coasts or are involved in cleanup efforts may be at risk.
