A study analyzed data from more than 40,000 teens (ages 12 to 17) and found alarmingly low rates (about 35%) of treatment completion. Nearly 60% of the adolescents started using cannabis between ages 12 and 14. Those who started cannabis at age 11 or younger had a success rate of just 12.9%. Co-occurring disorders, early use, and race impacted outcomes, with Hispanic and Pacific Islander teens more likely to complete treatment than Black or white adolescents. Boys were somewhat less likely than girls to complete treatment.
Colon cancer is often driven by cancer stem cells, which resist treatment and lead to relapse. In a recent study, researchers from Japan revealed how transcription factors CDX1 and CDX2 suppress cancer cell stemness by blocking β-catenin’s ability to activate key genes like LGR5. Their findings showed that CDX1/2 prevent the formation of key transcriptional complexes involving DSIF and PAF1, identifying these as critical regulators and potential therapeutic targets in colon cancer.
A study by investigators at the Icahn School of Medicine at Mount Sinai, in collaboration with colleagues from Rabin Medical Center in Israel and other collaborators, suggests that even the most advanced artificial intelligence (AI) models can make surprisingly simple mistakes when faced with complex medical ethics scenarios. The findings, which raise important questions about how and when to rely on large language models (LLMs), such as ChatGPT, in health care settings, were reported in the July 22 online issue of NPJ Digital Medicine.
