Objective: Optimal donor sizing for heart transplantation (HT) in adults with congenital heart disease (CHD) remains unclear, given the propensity for pulmonary hypertension related to shunting, staged repairs, and periods of pulmonary overcirculation. We studied HT outcomes related to donor size matching in the adult CHD population.
Methods: We conducted a retrospective cohort analysis of patients with CHD undergoing HT in the United States from January 1, 2000, to December 31, 2015. Patients were selected from the United Network for Organ Sharing database; 827 patients met inclusion criteria and were analyzed.
Results: At a median follow-up of 1462 days, 548 (66.3%) subjects were alive and 279 (33.7%) were deceased. All-cause mortality did not differ based on donor sizing (by predicted heart mass ratio: hazard ratio, 1.03; confidence interval, 0.86-1.23; P = .74). Pulmonary hypertension was not significantly associated with survival (by predicted heart mass ratio, χ = 2.01, P = .73).
Conclusions: Our data demonstrate that donor oversizing, to the extent used in current practice, does not affect survival after HT in adults with CHD. Our findings from the United Network for Organ Sharing database demonstrate that donor oversizing in these patients is not associated with improved mortality.

The role of surfactant proteins A and D (SP-A and SP-D) in lung clearance and translocation to secondary organs of inhaled nanoparticles was investigated by exposing SP-A and SP-D knockout (AKO and DKO) and wild type (WT) mice nose-only for 3 hours to an aerosol of 20 nm gold nanoparticles (AuNPs). Animals were euthanised at 0-, 1-, 7- and 28-days post-exposure. Analysis by inductively coupled plasma mass spectrometry (ICP-MS) of the liver and kidneys showed that extrapulmonary translocation was below the limits of detection.

Infective endocarditis used to frequently cause mortality in subjects having PDA before the advent of antibiotics and surgical ligation. It has been documented that clinically silent PDAs may cause infective complications of heart valves. We present case of an 18-years-old male who presented with palpitations and fever to our emergency department.

The evolution of left ventricular assist devices (LVADs) from large, pulsatile systems to compact, continuous-flow pumps has significantly improved implantation outcomes and patient mobility. Minimally invasive surgical techniques have emerged that offer reduced morbidity and enhanced recovery for LVAD recipients. Innovations in wireless power transfer technologies aim to mitigate driveline-related complications, enhancing patient safety and quality of life.

Particulate matter (PM) is a major component of ambient air pollution. PM exposure is linked to numerous adverse health effects, including chronic lung diseases. Air quality guidelines designed to regulate levels of ambient PM are currently based on the mass concentration of different particle sizes, independent of their origin and chemical composition.
