RESUMO
BACKGROUND: Music therapy (MT) can relieve distressing end-of-life symptoms, but little is known regarding its effect on caregivers who are at risk for emotional distress as their loved ones approach death. MEASURES: Quality of life (Linear Analogue Self-Assessment), depressive and anxiety symptoms (Patient Health Questionnaire for Depression and Anxiety), and stress (Role Overload Measure) pre-MT, post-MT and at 6-month follow-up, as well as a satisfaction survey post-MT. INTERVENTION: Single MT session for 20-45 minutes OUTCOMES: 15/20 completed MT intervention, 14 also completed pre-MT and post-MT assessments, and 9 completed assessments at all 3 timepoints. Post-MT satisfaction survey (n=14) showed 100% of caregivers were very satisfied with MT and would recommend to others, and found MT very effective for emotional support (85.7%), stress relief (78.6%), spiritual support (71.4%), general feeling of wellness (71.4%), relaxation (69.2%), and pain relief (33.3%). CONCLUSIONS: Research on MT is feasible for caregivers of inpatient hospice patients. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT03322228.

Pulmonary arterial hypertension (PAH) is a complex disease involving increased resistance in the pulmonary arteries and subsequent right ventricular (RV) remodeling. Ventricular-arterial interactions are fundamental to PAH pathophysiology but are rarely captured in computational models. It is important to identify metrics that capture and quantify these interactions to inform our understanding of this disease as well as potentially facilitate patient stratification. Towards this end, we developed and calibrated two multi-scale high-resolution closed-loop computational models using open-source software: a high-resolution arterial model implemented using CRIMSON, and a high-resolution ventricular model implemented using FEniCS. Models were constructed with clinical data including non-invasive imaging and invasive hemodynamic measurements from a cohort of pediatric PAH patients. A contribution of this work is the discussion of inconsistencies in anatomical and hemodynamic data routinely acquired in PAH patients. We proposed and implemented strategies to mitigate these inconsistencies, and subsequently use this data to inform and calibrate computational models of the ventricles and large arteries. Computational models based on adjusted clinical data were calibrated until the simulated results for the high-resolution arterial models matched within 10% of adjusted data consisting of pressure and flow, whereas the high-resolution ventricular models were calibrated until simulation results matched adjusted data of volume and pressure waveforms within 10%. A statistical analysis was performed to correlate numerous data-derived and model-derived metrics with clinically assessed disease severity. Several model-derived metrics were strongly correlated with clinically assessed disease severity, suggesting that computational models may aid in assessing PAH severity.
RESUMO
Pediatric patients awaiting heart transplant face high mortality rates due to donor organ shortages, including non-use of marginal donor hearts. We examined national trends in pediatric marginal donor heart use over time. UNOS data were queried for heart donors <18 years from 2005 to 2014. The proportion of donor hearts considered marginal was determined using previously cited marginal characteristics: left ventricular ejection fraction (LVEF) <50%, use of ≥2 inotropes, cerebrovascular death, CDC high-risk status, and eGFR < 30 mL/min/1.73 m2 . Disposition of donor hearts was determined and stratified by marginal donor status. Of 6778 pediatric hearts offered from 2005 to 2014, 2373 (35.0%) were considered marginal. Non-use of marginal donor hearts was significantly higher than that of donor hearts without any marginal characteristics (59.5% vs 20.3%, P < .001). In particular, LVEF < 50% and donor inotropes were associated with high rates of organ non-use among pediatric donors. Yet, non-use of marginal donor organs decreased from 67% to 48% from 2005 to 2014 (P < .001). Although the proportion of pediatric donor hearts used for pediatric patients has increased, more than half of donor hearts are declined for use in pediatric recipients due, in part, to perceived marginal status.

Children with congenital heart disease who undergo cardiac surgery are vulnerable to acute kidney injury (AKI). This study sought to evaluate the role of angiotensin-converting enzyme (ACE) inhibitors and other nephrotoxic medications in the risk for the development of AKI in neonates and children undergoing cardiac surgery. A retrospective review of all patients younger than 2 years admitted to the cardiac intensive care unit after cardiac surgery from March 2007 to September 2008 was conducted. Patients were included in the review if they received furosemide alone or in combination with an ACE inhibitor. Creatinine clearance was calculated, and the patient's maximal degree of AKI was classified by pRIFLE. A P value less than 0.05 was considered significant. Of the 319 patients who met the inclusion criteria, 149 (47%) received furosemide therapy alone and 170 (53%) received a combination of furosemide and an ACE inhibitor. Patients in the furosemide-only group (age, 5 months) were older than the patients who received both furosemide and an ACE inhibitor (age, 3.8 months; P = 0.024). Despite statistically higher Aristotle scores in the ACE-inhibitor group, the intraoperative variables did not differ between the two groups. Postoperatively, the ACE-inhibitor group had a decreased creatinine clearance (55.3 ml/min/1.73 m(2)) compared with the furosemide group (64.4 ml/min/1.73 m(2); P = 0.015) and an increased incidence of a pRIFLE maximal score of "F" (odds ratio [OR], 1.75; P = 0.033). However, after adjustment for additional risk factors, no difference in the occurrence of AKI resulted (OR, 0.939; P = 0.85) when patients received an ACE inhibitor. More than half of the study population received ACE inhibitors, but this treatment was not associated with an increase in AKI.

We sought to analyze the outcome of hemodynamically significant acute graft rejection in pediatric heart transplant recipients from a single-center experience. Acute graft rejection remains a major cause of morbidity and mortality for patients who undergo orthotopic heart transplantation and has been associated with the severity of the rejection episode. A retrospective review of all children experiencing a hemodynamically significant rejection episode after orthotopic heart transplantation was performed. Fifty-three patients with 54 grafts had 70 rejection episodes requiring intravenous inotropic support. Forty-one percent of these patients required high-dose inotropic support, with the remaining 59% of patients requiring less inotropic support. Overall graft survival to hospital discharge was 41% for patients in the high-dose group compared to 94% in the low-dose group. Six-month graft survival in patients who required high-dose inotropes remained at 41% compared to 44% in the low-dose group. Hemodynamically significant acute graft rejection in pediatric heart transplant recipients is a devastating problem with poor short- and long-term outcomes. Survival to hospital discharge is dismal in patients who require high-dose inotropic support. In contrast, survival to discharge is quite good in patients who require only low-dose inotropic support; however, six-month graft survival in this group is low secondary to a high incidence of graft failure related to worsening or aggressive transplant coronary artery disease.

OBJECTIVES: We sought to analyze the indications and outcome of extracorporeal membrane oxygenation (ECMO) for early primary graft failure and determine its impact on long-term graft function and rejection risk. BACKGROUND: Early post-operative graft failure requiring ECMO can complicate heart transplantation. METHODS: A retrospective review of all children requiring ECMO in the early period after transplantation from 1990 to 2007 was undertaken. RESULTS: Twenty-eight (9%) of 310 children who underwent transplantation for cardiomyopathy (n = 5) or congenital heart disease (n = 23) required ECMO support. The total ischemic time was significantly longer for ECMO-rescued recipients compared with our overall transplantation population (276 +/- 86 min vs. 242 +/- 70 min, p < 0.01). The indication for transplantation, for ECMO support, and the timing of cannulation had no impact on survival. Hyperacute rejection was uncommon. Fifteen children were successfully weaned off ECMO and discharged alive (54%). Mean duration of ECMO was 2.8 days for survivors (median 3 days) compared with 4.8 days for nonsurvivors (median 5 days). There was 100% 3-year survival in the ECMO survivor group, with 13 patients (46%) currently alive at a mean follow-up of 8.1 +/- 3.8 years. The graft function was preserved (shortening fraction 36 +/- 7%), despite an increased number of early rejection episodes (1.7 +/- 1.6 vs. 0.7 +/- 1.3, overall transplant population, p < 0.05) and hemodynamically comprising rejection episodes (1.3 +/- 1.9 vs. 0.7 +/- 1.3, overall transplant population, p < 0.05). CONCLUSIONS: Overall survival was 54%, with all patients surviving to at least 3 years after undergoing transplantation. None of the children requiring >4 days of ECMO support survived. Despite an increased number of early and hemodynamically compromising rejections, the long-term graft function is similar to our overall transplantation population.
