Background: Aboriginal peoples experience a disproportionate burden of disease, compared with other Canadians. However, relatively little information is available about mortality among Métis and non-Status Indians.
Methods: This study calculates potential years of life lost before age 75 (PYLL) for people aged 25 to 74 by all-cause and cause-specific mortality, and examines the effect of socio-economic factors on premature mortality. Age-specific and age-standardized PYLL rates were calculated for 11,600 Métis, 5,400 non-Status Indians, and 2,475,700 non-Aboriginal adults based on the number of person-years at risk up to age 75.
Results: Métis and non-Status Indian adults had about twice the risk of dying before age 75, compared with non-Aboriginal adults. While the largest percentage of PYLL was due to non-communicable diseases such as cardiovascular disease and cancer, relative and absolute inequalities were greatest for injuries. Socioeconomic indicators such as income, education and employment explained a large share of the disparities in premature mortality.
Interpretation: The results highlight the losses of potential years of life due to chronic diseases, as well as the possible importance of injury prevention programs for Métis and non-Status Indians.

Evaluation of the Current Urgency-Based Lung Allocation System in Korea with Simulation of the Eurotransplant Lung Allocation Score.

Article Synopsis
- The study highlights the high mortality rate of patients on the lung transplant waitlist in Korea, necessitating fair allocation policies due to a shortage of donors.
- Researchers simulated the Eurotransplant lung allocation score (ET-LAS) using data from the Korean Organ Transplantation Registry (KOTRY) to evaluate the current urgency-based system.
- Findings suggest that the existing allocation criteria may not effectively prioritize patients based on urgency, particularly for those not in the highest urgency status, indicating a need for policy revision.

Background & Aims: Mortality on the paediatric liver transplantation (pLT) waiting list (WL) is still an issue. We analysed the Italian pLT WL to evaluate the intention-to-treat (ITT) success rate and to identify factors influencing success.
Methods: All children (<18 years) listed for pLT in Italy between 2002-2018 were included (Era 1 [2002-2007]: centre-based allocation; Era 2 [2008-2014]: national allocation; Era 3 [2015-2018]: national allocation+mandatory-split policy).
Transplant center variability in utilizing nonstandard donors and its impact on the transplantation of patients with lower MELD scores.

There is a subset of patients with lower MELD scores who are at substantial risk of waitlist mortality. In order to transplant such patients, transplant centers must utilize "nonstandard" donors (eg, living donors, donation after circulatory death), which are traditionally offered to those patients who are not at the top of the waitlist. We used Organ Procurement and Transplantation data to evaluate center-level and region-level variability in the utilization of nonstandard donors and its impact on MELD at transplant among adult liver-alone non-status 1 patients transplanted from April 1, 2020, to September 30, 2022.

Article Synopsis
- The study aims to investigate income-related inequities in accessing primary (family doctor/nurse practitioner) and specialist healthcare among First Nations adults living off-reserve in Canada, highlighting a lack of research in this area.
- Using data from the 2017 Aboriginal Peoples Survey, the researchers performed logistic regression analysis to identify factors influencing healthcare utilization and applied the Horizontal Inequity index to measure disparities.
- Results indicate that higher income and education levels correlate with increased healthcare access among First Nations peoples, with inequities mainly driven by disparities in income and education even after adjusting for healthcare needs.
