Correspondence: Pediatric Heart Transplantation with Donation after Circulatory Death nej.md/4j5oEi0
#Surgery #Cardiology
ALT A figure from the Correspondence "Pediatric Heart Transplantation with Donation after Circulatory Death." Shown are three of the five pediatric hearts that were successfully recovered and transplanted, including those obtained from an infant (Donor 2), a neonate (Donor 3), and a toddler (Donor 4).

Thank you so much to @washingtonpost for featuring our work and bringing attention to this important topic!
#LungCancerScreening
Lung cancer screening saves lives, but too many eligible patients are missing out.
New research from our #ThoracicSurgery department highlights a critical gap:
- only 1 in 6 eligible patients discussed screening with a clinician in the past year.
Early detection matters. Let's make screening a priority🫁

In five pediatric heart transplantations, a rapid-recovery technique involving oxygenated preservation enabled the use of donated hearts without reanimation. All recipients had normal biventricular function by day 7. Full study results: nej.md/4j5oEi0

1/ My first paper in PGY2 residency landed in JAMA Oncology, and the truth is it was won before I ran a single analysis. It came down to how I chose the question. 8 Years later, I realized that very few trainees got taught about how to pick a first research idea. Lets try a bit

Presented at #ASCO26:
Among patients with previously treated metastatic pancreatic ductal adenocarcinoma, the RAS(ON) inhibitor daraxonrasib led to significantly longer overall survival and progression-free survival than chemotherapy. Full phase 3 RASolute 302 trial results: nej.md/4nWaxvM
@ASCO
ALT Graph from a study published in the New England Journal of Medicine on daraxonrasib versus chemotherapy for metastatic pancreatic cancer. The x-axis represents months, and the y-axis shows the percentage of patients alive. Two lines indicate survival rates: daraxonrasib (blue) and chemotherapy (gray). The bottom section lists patients at risk over time. Title and journal logo are included.
