Objective. The lung allocation score (LAS) resulted in a lung transplantation (LT) selection process guided by clinical acuity. We sought to evaluate the relationship between LAS and outcomes. Methods. We analyzed Scientific Registry of Transplant Recipient (SRTR) data pertaining to recipients between 2005 and 2012. We stratified them into quartiles based on LAS and compared survival and predictors of mortality. Results. We identified 10,304 consecutive patients, comprising 2,576 in each LAS quartile (quartile 1 (26.3-35.5), quartile 2 (35.6-39.3), quartile 3 (39.4-48.6), and quartile 4 (48.7-95.7)). Survival after 30 days (96.9% versus 96.8% versus 96.0% versus 94.8%), 90 days (94.6% versus 93.7% versus 93.3% versus 90.9%), 1 year (87.2% versus 85.0% versus 84.8% versus 80.9%), and 5 years (55.4% versus 54.5% versus 52.5% versus 48.8%) was higher in the lower groups. There was a significantly higher 5-year mortality in the highest LAS group (HR 1.13, p = 0.030, HR 1.17, p = 0.01, and HR 1.17, p = 0.02) comparing quartiles 2, 3, and 4, respectively, to quartile 1. Conclusion. Overall, outcomes in recipients with higher LAS are worse than those in patients with lower LAS. These data should inform more individualized evidence-based discussion during pretransplant counseling.

Objective: To review and compare robot-assisted ipsilateral ureteroureterostomy (RALUU) and laparoscopic ipsilateral uretero-ureterostomy (LUU) in terms of efficacy and outcomes.
Methods: Clinical data of 65 children with complete renal ureteral duplication deformity admitted to the First Affiliated Hospital of Zhengzhou University from January 2015 to December 2022 were collected. Among these, 42 patients underwent laparoscopic ureteroureterostomy (LUU), designated as the LUU group, while 23 patients received robot-assisted laparoscopic ureteroureterostomy (RALUU), designated as the RALUU group.

The December 2024 US Food and Drug Administration (FDA) approval of Mesoblast's Ryoncil (remestemcel-L-rknd)-allogeneic bone marrow mesenchymal stromal cell (MSC(M)) therapy-in pediatric acute steroid-refractory graft-versus-host-disease finally ended a long-lasting drought on approved MSC clinical products in the United States. While other jurisdictions-including Europe, Japan, India, and South Korea-have marketed autologous or allogeneic MSC products, the United States has lagged in its approval. The sponsor's significant efforts and investments, working closely with the FDA addressing concerns regarding clinical efficacy and consistent MSC potency through an iterative process that spanned several years, was rewarded with this landmark approval.
