Impact of Left Ventricular Assist Device Exchange on Outcomes After Heart Transplantation

This study examined whether LVAD exchanges affect posttransplantation outcomes.MethodsThis study focused on adult patients in the Organ Procurement and Transplantation Network database who were bridged to transplant with a LVAD implanted between 2007 and 2017. Patients who underwent LVAD exchange were compared with those supported with a single device. The primary end point was all-cause mortality at 1, 2, and 5 years after transplantation. The impact of device exchange on risk-adjusted outcomes was examined using Cox proportional hazards models.ResultsAmong 8239 patients who met the inclusion criteria, there were 611 pump exchanges in 560 patients (7% of recipients). The pump exchange rate was 6.24 events per 100 patient-years. Survival at 5 years was lower for those who underwent LVAD exchange (69.4% vs 77.5%, log-rank P = .027). This finding was similar for risk-adjusted 5-year mortality (hazard ratio, 1.36; 95% confidence interval, 1.11 to 1.67; P = .003). Subgroup analysis revealed lower 5-year survival for female recipients who underwent LVAD exchange (55.4% vs 79.7%, log-rank P

Authors: Tönshoff B Abstract Introduction: The goal of immunosuppressive therapy post-transplantation in pediatric renal transplant recipients is to prevent acute and chronic rejection while minimizing drug side effects. Most therapies alter immune response mechanisms but are not immunologically specific, and a careful balance is required to find the dose that prevents rejection of the graft, while minimizing the risks of over-immunosuppression leading to infection and cancer.Areas covered: This review article focuses on immunosuppressive therapy in pediatric renal transplant recipients, but many aspects can b...

AbstractReceptor tyrosine kinases (RTKs) are implicated in cardiovascular growth and remodelling. We aimed to identify the plasma levels of RTKs and related proteins and their association with haemodynamic alterations in heart failure (HF) and related pulmonary hypertension (PH) following heart transplantation (HT). Using proximity extension assay, 28 RTKs and related proteins were analysed in plasma from 20 healthy controls and 26 HF patients before and 1-year after HT. In end-stage HF, out of 28 RTKs, plasma vascular endothelial growth factor-D (VEGF-D) and human epidermal growth factor-4 (HER4) were elevated compared to controls (p

Commentary on Recent Evidence for Cognitive Decline to Precede Amyloid Aggregation in Alzheimer's Disease https://www.fightaging.org/archives/2020/01/commentary-on-recent-evidence-for-cognitive-decline-to-precede-amyloid-aggregation-in-alzheimers-disease/ I can't say that I think the data presented in the research noted here merits quite the degree of the attention that it has been given in the popular science press. It is interesting, but not compelling if its role...

This study adds to the body of evidence in describing incidence and type of cardiac events experienced by an allogeneic and autologous HSCT population at one institution from 2012-2017. Sixty-five patients (9.8%) experienced cardiac events, including atrial arrhythmia (N = 39), acute heart failure (N = 9), acute coronary syndrome (N = 7), new onset hypertension (N = 9), with a few instances of bradycardia, ventricular arrhythmia, pericardial effusion, and pericarditis. Our multivariable regression analysis identified age (older), creatinine (higher) and history of coronary artery disease to significantly correlate with ris...

For as long as I can remember, “Peeling off the layers to reveal the real” has been my credo. In a dream, the words “Bare Boldly,” echoed through my sleeping but ever so active brain.” When messages come through that insistently, they can’t be ignored. My inner and outer work as a hybrid therapist-journalist prepare me to take this on every day. When that happens, I question if I am too self-revealing. Last year, I penned an article for Psych Central called When A Therapist and Journalist Comes Clean About Her Self Doubt. It takes a confessional tone as I admit that the way I present isn...
