Objective: Malignancy is the leading cause of death among heart-transplant recipients. There is a higher incidence of post-transplant malignancy in heart-transplant recipients than in kidney-transplant recipients. This study sought to assess the incidence of malignancy in heart-transplant recipients in Taiwan.
Methods: This is a retrospective chart review.
Results: From 1987 to 2008, 291 patients who underwent heart transplantation and survived for more than 1 month were enrolled. Seventeen patients (5.8%) developed de novo malignancies including skin cancers (three), post-transplant lymphoproliferative diseases (seven) and solid-organ malignancies (seven). Solid-organ malignancies affected prostate, liver, urinary bladder, kidney, lung, larynx, pancreas and brain in seven patients. Malignancy was responsible for 7% and 13% of all death for heart-transplant recipients who lived for more than 1 year and more than 5 years. The cumulative incidence of 1.03% at 1 year, 4.2% at 5 years and 8.1% at 10 years in our patients was much lower than the incidences reported in the multicentre registry of the International Society for the Heart and Lung Transplantation and in the Western series. The incidence was especially low for skin cancers. Compared with previous reports of kidney-transplant recipients in Taiwan, the incidence of post-transplant malignancy was not significantly increased.
Conclusions: The incidence of post-transplant malignancy was low in Chinese heart-transplant recipients compared with heart-transplant recipients in Western countries. It resulted from a relative rarity of skin cancers in the Chinese population.

Background: Cytomegalovirus (CMV) is a significant cause of morbidity and death in solid organ transplant recipients. Pre-emptive treatment of patients with CMV viraemia using antiviral agents has been suggested as an alternative to routine prophylaxis to prevent CMV disease. This is an update of a Cochrane review first published in 2006 and updated in 2013.

Objectives: To investigate through a meta-analysis of comparative studies the impact of donor type (brain death DBD vs circulatory death DCD) on the short- and long-term outcomes of lung transplantation(LTx).
Methods: Literature search (terms "lung transplantation" AND "donation after circulatory death") was performed up to July 2022 and studies comparing outcomes of LTx from DCD versus DBD were selected. Primary endpoints were early and long-term mortality.

Background: Better risk stratification is needed to evaluate patients with non-ischemic cardiomyopathy (NICM) for prophylactic implantable cardioverter-defibrillators (ICD). Growing evidence suggests cardiac magnetic resonance imaging (CMR) may be useful in this regard.
Objective: We aimed to determine if late-gadolinium enhancement (LGE) seen on CMR (dichotomized as none/minimal <2% vs significant ≥2%) predicts appropriate ICD therapies (primary endpoint) and/or all-cause mortality/transplant/left-ventricular assist device (LVAD) implantation (secondary endpoint) in NICM patients.
Coronavirus disease 2019 (COVID-19) poses significant risks for solid organ transplant recipients, who have atypical but poorly characterized immune responses to infection. We aim to understand the host immunologic and microbial features of COVID-19 in transplant recipients by leveraging a prospective multicenter cohort of 86 transplant recipients age- and sex-matched with 172 non-transplant controls. We find that transplant recipients have higher nasal SARS-CoV-2 viral abundance and impaired viral clearance, and lower anti-spike IgG levels.

Introduction: Heplisav-B, a CpG-adjuvanted recombinant hepatitis B virus (HBV) vaccine, has a higher seroprotection rate and immunogenicity than the conventional HBV vaccine. This study aimed to identify the predictors of HBV seroprotection post-transplantation in thoracic organ transplant recipients who received Heplisav-B.
Methods: We conducted a retrospective study of adult thoracic organ (heart and lung) transplant recipients at Mayo Clinic sites in Minnesota, Arizona, and Florida between January 2020 and August 2023.
