Clinical impact of the Z0011 trial on axillary surgical management in Australia and New Zealand from the BreastSurgANZ Quality Audit.

Background: The clinical management of the axilla in early breast cancer has changed since the Z0011 trial, which showed that axillary lymph node dissection (ALND) is not necessary in select patients with a positive sentinel lymph node biopsy (SLNB). Studies have shown a significant decrease in the rates of completion ALND (cALND) since Z0011. The aims of this study were to investigate the effect of the Z0011 trial on the management of positive axillary sentinel nodes and the trends in axillary surgical management since 2005 in Australia and New Zealand.

Donation After Circulatory Death: A New Frontier.

Purpose Of Review: To highlight the current global experience with DCD heart transplantation and explore the evolution of, and compare preservation strategies; examine early clinical outcomes, and discuss the growing use of DCD donors as a new frontier in heart transplantation.

Recent Findings: The two strategies of DCD heart preservation include NMP using the OCS Heart and TA-NRP followed by either: NMP or CSS. Better understanding the limits of cold ischaemia following TA-NRP will aid in distant procurement.

Heart Transplantation From DCD Donors in Australia: Lessons Learned From the First 74 Cases.

Heart transplantation from donation after circulatory death (DCD) donors has the potential to substantially increase overall heart transplant activity. The aim of this report is to review the first 8 y of our clinical heart transplant program at St Vincent's Hospital Sydney, to describe how our program has evolved and to report the impact that changes to our retrieval protocols have had on posttransplant outcomes. Since 2014, we have performed 74 DCD heart transplants from DCD donors utilizing a direct procurement protocol followed by normothermic machine perfusion.

Three-dimensionally-printed anthropomorphic physical phantom for mammography and digital breast tomosynthesis with custom materials, lesions, and uniform quality control region.

Anthropomorphic breast phantoms mimic patient anatomy in order to evaluate clinical mammography and digital breast tomosynthesis system performance. Our goal is to create a modular phantom with an anthropomorphic region to allow for improved lesion and calcification detection as well as a uniform region to evaluate standard quality control (QC) metrics. Previous versions of this phantom used commercial photopolymer inkjet three-dimensional printers to recreate breast anatomy using four surfaces that were fabricated with commercial materials spanning only a limited breast density range of 36% to 64%.
