Updating the kidney donor risk index: Removing donor race and hepatitis C virus status.

This study reports the results of a recalculation of the kidney donor risk index (KDRI) formula requested by the Organ Procurement and Transplantation Network's Minority Affairs Committee to remove donor race and hepatitis C virus (HCV) status variables. The updated KDRI model was fit on adult, deceased donor, solitary kidney, first-time transplants from 2018 through 2021. Deceased donors from 2018 through 2021 were included in a counterfactual analysis to evaluate how the kidney donor profile index (KDPI) would change if race and HCV seropositivity were excluded.

Outcomes in Patients With Henoch-Schönlein Purpura After Kidney Transplantation: A Propensity Score Matched Study.

Aim: Henoch-Schönlein purpura (HSP) nephritis leads to end-stage renal disease (ESRD) in upto 3% of cases, necessitating kidney transplantation (KT). This study compared graft and patient survival outcomes between HSP and non-HSP KT recipients and identified factors associated with HSP recurrence.

Methods: Data from the Scientific Registry of Transplant Recipients (SRTR) were analysed for adult and paediatric KT patients listed between January 2005 and April 2021.

Access to Kidney Transplantation for Minority Children With End-Stage Renal Disease and Predictors of Post-Transplant Outcome: Impact of Race and Ethnicity.

Background: Racial disparities in access to kidney transplantation (KT) have been described among children with end-stage renal disease in the United States. It has been suggested that these disparities stem from a combination of clinical and socioeconomic factors.

Methods: We evaluated data from the US Scientific Registry of Transplant Recipients (SRTR) of all pediatric (< 18 years old) KT recipients from 1999 to 2014 and compared outcomes by race or ethnicity: Hispanic, non-Hispanic Whites (NHW), and non-Hispanic Blacks (NHB).

Soil carbon in the world's tidal marshes.

Tidal marshes are threatened coastal ecosystems known for their capacity to store large amounts of carbon in their water-logged soils. Accurate quantification and mapping of global tidal marshes soil organic carbon (SOC) stocks is of considerable value to conservation efforts. Here, we used training data from 3710 unique locations, landscape-level environmental drivers and a global tidal marsh extent map to produce a global, spatially explicit map of SOC storage in tidal marshes at 30 m resolution.
