Background: In October 2018, a new heart allocation policy was implemented with intent of prioritizing the sickest patients and decreasing waitlist time. We examined the effects of the new policy on transplant practices and outcomes 1 year before and 1 year after the change.
Methods: Transplant recipients from October 2017 to September 2019 at our institution were identified and divided into 2 cohorts, a preallocation and postallocation criteria change. Patient demographics, clinical data, and bridging strategy were assessed. Early outcomes including ischemic time, severe primary graft dysfunction, need for renal replacement therapy, and duration of hospital stay were investigated.
Results: In the 12 months before the change, 38 patients were transplanted as compared to 33 patients in the 12 months after the change. The average wait-time to transplant decreased after the allocation change (49 versus 313 d, = 0.02). Patients were more likely to be bridged with an intra-aortic balloon pump (45% versus 3%) and less likely to be supported with a durable left ventricular assist device (LVAD) after the change (24% versus 82%). There was an increase in total ischemic time after the change (177 versus 117 min, ≤ 0.01). There were no significant differences in other early posttransplant outcomes.
Conclusions: Implementation of the new allocation system for heart transplantation resulted in dramatic changes in the bridging strategy utilized at our institution. Temporary mechanical support usage increased following the change and the number of recipients supported with durable LVADs decreased. Early posttransplant outcomes appear similar.

Adult left lobe living donor liver transplantation has long been practiced nearly exclusively in Japan. To overcome the potential risks of small-for-size syndrome and hepatic venous outflow obstruction associated with the use of left lobe grafts, center-specific countermeasures such as splenectomy, meticulous hepatic venous reconstruction, and inclusion of the caudate lobe have been implemented, resulting in short- and long-term results comparable with those of right lobe graft in high-volume centers. A recent systematic review and meta-analysis confirmed these observations; however, the indications and techniques of adult left lobe living donor liver transplantation have yet to be standardized.

The prefibrotic phase of primary myelofibrosis (pre-PMF) represents a distinct subentity within the spectrum of myeloproliferative neoplasms (MPNs), recognized by the World Health Organization (WHO) and the International Consensus Classification (ICC). Pre-PMF is characterized by unique morphological, clinical, and molecular features, distinguishing it from essential thrombocythemia (ET) and overt myelofibrosis (overt-PMF). The diagnostic process for pre-PMF relies on bone marrow histology, identification of molecular mutations and exclusion of other myeloid neoplasms.

Background: Infections are a common complication among lung transplant recipients (LuTR), particularly in the first year post-transplant, with respiratory tract infections (RTI) being predominant. Syndromic molecular panels have been suggested to reduce morbidity and mortality by providing a diagnosis quickly. However, integrating these panels into clinical practice remains debated.

Background And Objectives: High-quality ABO antibody titre testing is required for ABO-incompatible haematopoietic stem cell transplantation and kidney transplantation. To assess the feasibility of automated ABO titration as an alternative to manual and semi-automatic titration during the peri-transplant period, a comparative study was conducted internally in a transfusion medicine laboratory.
Materials And Methods: This study was performed in two stages.
