Bilateral Nephrectomy For Refractory Hypertension In A Patient With Esrd On Intermittent Hemodialysis, Kavya Balusu, Vijay Sheldon, Arjun Sekar

Advances in Clinical Medical Research and Healthcare Delivery

In nearly 20 percent of patients with end-stage renal disease (ESRD), hypertension remains poorly controlled despite pharmacological therapy and volume reduction through dialysis. Further, morbidity from hospitalization for hypertensive crisis is significantly higher in patients with ESRD than in patients without ESRD. For those who fail conventional therapies for hypertension, therapeutic bilateral nephrectomy can be considered as a last resort option. With appropriate candidate selection, patients are expected to have improved quality of life. We describe the case of a 37-year-old African American male with ESRD on intermitted hemodialysis who underwent bilateral nephrectomy for the management of hypertension refractory to …

Adult Out Of Hospital Cardiac Arrest Criteria For Extracorporeal Cardiopulmonary Resuscitation Activation May Not Be The Same For Pediatric Out Of Hospital Cardiac Arrest, Lindsay Fick, Sherouk A. Abdelmoity, Jennifer Flint, Ashley Sherman, Jenna Miller

Presentations

Pediatric out-of-hospital cardiac arrest (OHCA) remains a high-mortality event, with survival to discharge consistently below 10%. Although extracorporeal cardiopulmonary resuscitation (E-CPR) improves outcomes for in-hospital cardiac arrest, its application in the pre-hospital environment is not well defined for pediatrics. Identifying which pediatric patients might benefit from OHCA ECPR activation is essential for developing feasible pre hospital pediatric E-CPR systems. Preliminary analysis of applying  criteria for adult OHCA ECPR activation can provide a crucial next step in establishing feasibility and applicability for the pediatric patient population.

Methods

A single center retrospective review was conducted of pediatric OHCA cases presenting from 2018–2025. …

Quantitative Echocardiography Markers To Denote Severity Of Tricuspid Regurgitation Compared To Cardiac Mri In Single Right Ventricle Variants, Tony Zunica, Daniel Forsha, Janelle Noel-Macdonnell, Anmol Goyal

Posters

Background: Single right ventricle and Hypoplastic Left Heart Syndrome (HLHS) are congenital heart diseases that require multiple palliative surgeries to create a single right ventricular system. 25-30% of these patients develop significant tricuspid regurgitation (TR), which is associated with worse outcomes among all stages of palliation. Echocardiography remains the cornerstone imaging modality for serial evaluation in these patients. However, estimating tricuspid regurgitation is highly subjective in the pediatric population, necessitating need for reliable and reproducible quantitative echocardiography markers. Currently, cardiac magnetic resonance (CMR) is considered the gold standard for quantification of tricuspid regurgitation with good accuracy and reproducibility. Objectives/Goal: Our …

Division of Cardiology Faculty Papers

Background: Acute cellularrejection (ACR) remains a major cause of morbidity afterhearttransplantation despite advances in immunosuppression. Whole genometranscriptomicprofiling offers a systems-based, unbiased approach to elucidate the molecular mechanisms underlying ACR. However, noninvasive,longitudinal biomarker assessments capable of capturing the temporal dynamics ofrejection biology remain scarce.

Methods: RNA sequencing ofperipheralblood fromheart transplant recipients before, during, and after ACR was compared with nonrejection controls. Pathway analysis was conducted using differentially expressed genes (DEGs), and a machine learning approach was applied to assessgene-based prediction of ACR.

Results: A total of 235 rejection-specific significant DEGs and 863 postrejection DEGs (false discovery rate < 0.05) were identified. During ACR, DEGs were enriched for T-cell activation/differentiation, apoptosis, and B-cell receptor signaling pathways. By combining the 2 sets of DEGs, a panel of 71 common genes was identified that reflected the significant, longitudinal transcriptomic dynamics of ACR. In an elastic net machine learning-based classifier, DYNLL1 and SERF2 were …

• ALCAPA is a rare congenital heart defect seen in about one in 300,000 live births. • ALCARPA is an even rarer subset of ALCAPA with the LCA originating from the RPA. • Few cases report ALCARPA associated with coarctation of the aorta. • Coarctation and VSD may cause PH with antegrade LCA flow. • These defects are hard to diagnose and require coronary imaging before surgery.

The Influence Of Preoperative Bowel Preparation On Surgical Site Infection In Pediatric Colorectal Surgery., Katlyn G. Mckay, Naomi-Liza Denning, Rebecca M. Rentea, Eunice Y. Huang

Manuscripts, Articles, Book Chapters and Other Papers

Surgical site infection (SSI) is one of the most common nosocomial infections that occur in pediatric patients in the United States, with colorectal procedures consistently demonstrating the highest rates of SSI. Strategies to reduce SSI in colorectal surgery include standardized perioperative colorectal care bundles, which commonly incorporate preoperative bowel preparation. Robust adult literature exists supporting the use of mechanical bowel preparation in combination with oral antibiotics to mitigate SSI; however, pediatric evidence remains less definitive. Current pediatric literature shows heterogeneity of bowel preparation use amongst surgeons, with existing literature consisting primarily of small retrospective studies. A well-designed pediatric randomized controlled …
