To determine whether engaging in advance care planning (ACP) using a formal tool, Voicing My CHOiCES (VMC), would alleviate adolescent and young adults (AYAs) anxiety surrounding ACP and increase social support and communication about end-of-life care preferences with family members and health care providers (HCPs).

A total of 149 AYAs aged 18–39 years receiving cancer-directed therapy or treatment for another chronic medical illness were enrolled at seven US sites. Baseline data included prior ACP communication with family members and HCPs and measures of generalized anxiety, ACP anxiety, and social support. Participants critically reviewed each page of VMC and then completed three pages of the document. ACP anxiety was measured again immediately after the completion of VMC pages. One month later, participants repeated anxiety and social support measures and were asked if they shared what they had completed in VMC with a family member or HCP.

At baseline, 50.3% of participants reported that they previously had a conversation about EoL preferences with a family member; 19.5% with an HCP. One month later, 65.1% had subsequently shared what they wrote in VMC with a family member; 8.9% shared with an HCP. Most (88.6%) reported they would not have had this conversation if not participating in the study. No significant changes occurred in social support. There was an immediate drop in anxiety about EoL planning after reviewing VMC which persisted at 1 month. Generalized anxiety was also significantly lower 1 month after reviewing VMC.

Having a document specifically created for AYAs to guide ACP planning can decrease anxiety and increase communication with family members but not necessarily with HCPs. Future research should examine ways ACP can be introduced more consistently to this young population to allow their preferences for care to be heard, respected, and honored, particularly by their healthcare providers.

Myocardial strain measurements are increasingly used to detect complications following heart transplantation. However, the temporal association of these changes with allograft rejection is not well defined. The aim of this study was to describe the evolution of strain measurements prior to the diagnosis of rejection in paediatric heart transplant recipients.

All paediatric heart transplant recipients (2004–2015) with at least one episode of acute rejection were identified. Longitudinal and circumferential strain measurements were assessed at the time of rejection and retrospectively on all echocardiograms until the most recent negative biopsy. Smoothing technique (LOESS) was used to visualise the changes of each variable over time and estimate the time preceding rejection at which alterations are first detectable.

A total of 58 rejection episodes were included from 37 unique patients. In the presence of rejection, there were decrements from baseline in global longitudinal strain (−18.2 versus −14.1), global circumferential strain (−24.1 versus −19.6), longitudinal strain rate (−1 versus −0.8), circumferential strain rate (−1.3 versus −1.1), peak longitudinal early diastolic strain rate (1.3 versus 1), and peak circumferential early diastolic strain rate (1.5 versus 1.3) (p<0.01 for all). The earliest detectable changes occurred 45 days prior to rejection with simultaneous alterations in myocardial strain and ejection fraction.

Changes in graft function can be detected non-invasively prior to the diagnosis of rejection. However, changes in strain occur concurrently with a decline in ejection fraction. Strain measurements aid in the non-invasive detection of rejection, but may not facilitate earlier diagnosis compared to more traditional measures of ventricular function.
