Vasoplegia occurs in up to 16% of patients who undergo heart transplantation (HT) and is associated with significant morbidity and mortality. We present a case of a 61-year-old man with ischemic cardiomyopathy receiving sacubitril/valsartan (Entresto; Novartis, Cambridge, MA) who developed profound hypotension after HT. He was treated with intravenous methylene blue and high-dose vasopressors, but developed acute kidney injury requiring dialysis and a prolonged stay in the intensive care unit. This case supports a potent vasodilatory effect of sacubitril/valsartan, and if confirmed by other studies, might warrant consideration for withholding treatment while awaiting HT, particularly in patients with risk factors for vasoplegia.

Introduction: Organ transplant recipients face a substantial risk of developing posttransplant lymphoproliferative disorders (PTLD). In over 90% of cases with B-cell PTLD following solid organ transplantation, the Epstein-Barr virus (EBV) genome is promptly identified, usually within the initial year. A continuing discussion revolves around the efficacy of antiviral prophylaxis in mitigating the incidence of PTLD in solid organ transplant (SOT) patients.

Allogeneic chimeric antigen receptor (CAR) T cells targeting disialoganglioside-GD2 (ALLO_GD2-CART01) could be a therapeutic option for patients with relapsed or refractory, high-risk neuroblastoma (r/r HR-NB) whose tumors did not respond to autologous GD2-CART01 or who have profound lymphopenia. We present a case series of five children with HR-NB refractory to more than three different lines of therapy who received ALLO_GD2-CART01 in a hospital exemption setting. Four of them had previously received allogeneic hematopoietic stem cell transplantation.

Targeting the cardiomyocyte cell cycle is a promising strategy for heart repair following injury. Here, we identify a cardiac-regeneration-associated PIWI-interacting RNA (CRAPIR) as a regulator of cardiomyocyte proliferation. Genetic ablation or antagomir-mediated knockdown of CRAPIR in mice impairs cardiomyocyte proliferation and reduces heart regenerative potential.

Introduction: Whether the implementation of a multimodal prehabilitation program is effective and safe for high-risk heart or lung transplantation candidates, whose condition prevents hospital discharge, is unclear.
Methods: We conducted a retrospective study at a cardiothoracic transplant center in Chile. Two cohorts of hospitalized patients listed for heart or lung transplant were studied: the first underwent traditional (historical) and nonstructured prehabilitation, and the second underwent protocol-driven multimodal prehabilitation (MP).
