Controlled donation after circulatory determination of death (DCD), where death is determined after cardiac arrest, has been responsible for the largest quantitative increase in Canadian organ donation and transplants, but not for heart transplants. Innovative international advances in DCD heart transplantation include direct procurement and perfusion (DPP) and normothermic regional perfusion (NRP). After death is determined, DPP involves removal and reanimation of the arrested heart on an ex situ organ perfusion system. ⋯ Review of current evidence and international experience of DCD heart donation (DPP and NRP) determined that DCD heart donation could be used to provide opportunities for more heart transplants in Canada, saving additional lives. Although candid discussion identified a number of potential barriers and challenges for implementing DCD heart donation in Canada, it was determined that DPP implementation is feasible (pending regulatory approval for the use of an ex situ perfusion device in humans) and in alignment with current medical guidelines for DCD. Nevertheless, further work is required to evaluate the consistency of NRP with current Canadian death determination policy and to ensure the absence of brain perfusion during this process.

Observational Study
Prevalence and risk factors of preoperative malnutrition risk in older patients and its impact on surgical outcomes: a retrospective observational study.
Elderly patients are vulnerable to malnutrition and we have started systematic screening for preoperative malnutrition risk in our institution. This study aims to determine the prevalence and risk factors of preoperative malnutrition risk among elderly surgical patients, and its impact on surgical outcomes. ⋯ Preoperative malnutrition risk is prevalent among the elderly. Patients at high malnutrition risk have increased risk of postoperative complications and longer hospital LOS. Patients with high comorbidity burden and frailty should be screened for malnutrition so that nutritional optimization can be sought.

Family veto in organ donation: the experiences of Organ and Tissue Donation Coordinators in Ontario.
In Ontario, an individual's registered wish for organ donation is legally valid consent following death. Family veto occurs when the deceased donor's substitute decision-maker (SDM) overrides this consent to donate, evoking a legal and ethical conflict. The objective of this study was to examine the experiences of Organ and Tissue Donation Coordinators (OTDCs) working with SDMs who vetoed a deceased donor's consent for organ donation. ⋯ This study highlights important considerations about organ donation authorization processes in Ontario. Findings support practice changes towards reducing family veto and further research nationally. Collaborations with key stakeholders are warranted to align healthcare practices, donation policies, and education initiatives towards a shared goal of increasing organ donation.
