Abstract OBJECTIVES The aim of this study was to evaluate the impact of institutional volume on long-term outcomes following lung transplantation (LTx) in the USA. METHODS Adults undergoing LTx were identified in the United Network for Organ Sharing registry. Patients were divided into equal size tertiles according to the institutional volume. All-cause mortality following LTx was evaluated using the risk-adjusted multivariable Cox regression and the Kaplan–Meier analyses, and compared between these volume cohorts at 3 points: 90 days, 1 year (excluding 90-day deaths) and 10 years (excluding 1-year deaths). Lowess smoothing plots and receiver-operating characteristic analyses were performed to identify optimal volume thresholds associated with long-term survival. RESULTS A total of 13 370 adult LTx recipients were identified. The mean annual centre volume was 33.6 ± 20.1. After risk adjustment, low-volume centres were found to be at increased risk for 90-day mortality, [hazard ratio (HR) 1.56, P < 0.001], 1-year mortality excluding 90-day deaths (HR 1.46, P < 0.001) and 10-year mortality excluding 1-year deaths (HR 1.22, P < 0.001). These findings persisted when the centre volume was modelled as a continuous variable. The Kaplan–Meier analysis also demonstrated significant reductions in survival at each of these time points for low-volume centres (each P < 0.001). The 10-year survival conditional on 1-year survival was 37.4% in high-volume centres vs 28.0% in low-volume centres (P < 0.001). The optimal annual volume threshold for long-term survival was 26 LTx/year. CONCLUSIONS The institutional volume impacts long-term survival following LTx, even after excluding deaths within the first post-transplant year. Identifying the processes of care that lead to longer survival in high-volume centres is prudent.

Our review of the CITES trade database confirmed that the ball python is the most exported species by Togo; with 1,657,814 live individuals – comprising 60% of all live reptiles – reported by importing countries since 1978 (almost 55,000 annually since 1992). In total, 99% of the ball pythons legally exported from Togo under CITES were intended for commercial use, presumably as exotic pets. Since the turn of the century, wild-sourced snakes exported from Togo have been largely replaced with ranched snakes, to the extent that in the last 10 years 95% of these live exports were recorded using CITES source code “R” with the majority destined for the USA. We found discrepancies in the CITES trade database that suggest ball python exports were consistently underestimated by Togo and that both ranched and wild-sourced ball python annual quotas have been exceeded on multiple occasions including as recently as 2017. Furthermore, our field visits to seven of these “python farms” revealed that they are also involved in the commercial trade in at least 46 other reptile species, including eight that are already involved in formal CITES trade reviews due to concerns regarding their sustainability and legality. Ranching operations in West Africa were once thought to provide a degree of protection for the ball python; however, in light of recent research, there is growing concern that ranching may not confer any significant net conservation benefits. Further scrutiny and research are required to ensure the long-term survival of wild ball python and other reptile species populations in Togo.
