Background And Objectives: Chronic kidney disease (CKD) is a major public health concern that uniquely impacts older Black Americans, a population also likely to have family members also diagnosed with CKD. This study aimed to (1) describe how participants viewed their decision preferences considering the experiences of family, and friends previously diagnosed with CKD, and (2) to understand how these social complexities informed their own decisions for future CKD care.
Research Design And Methods: Utilizing a phenomenologically-informed approach, this study explored participants' perceptions of how patients and their family members' experiences with CKD influenced treatment-related decision-making.
Cheek swabs, heterogeneous samples consisting primarily of buccal epithelial cells, are widely used in pediatric DNA methylation studies and biomarker creation. However, the decrease in buccal proportion with age in adults remains unexamined in childhood. We analyzed cheek swabs from 4626 typically developing children 2-months to 20-years-old.

Article Synopsis
- The study explored how psilocybin-assisted therapy (PAT) impacts personality traits in people with alcohol use disorder (AUD), hypothesizing it would reduce trait impulsiveness and improve drinking behavior.
- Eighty-four AUD patients were divided into two groups (psilocybin vs. placebo) and assessed for changes in personality traits over time, finding significant personality shifts in the psilocybin group, including reduced neuroticism and increased openness.
- The results indicated that lower impulsiveness correlated with decreased alcohol consumption, particularly among those who drank at risk before treatment, pointing to potential benefits of PAT in addressing both personality and drinking behaviors.
