Background: Phosphatidylserine (PS) is a procoagulant phospholipid enriched on surfaces of activated vascular cells including platelets, endothelium, monocytes, and microvesicles. As a molecular driver of thrombosis accessible to drug blockade, PS is an attractive pharmacologic target for modulating thrombogenesis, with potentially reduced bleeding risk compared to anticoagulant and antiplatelet therapies.

Objectives: Test antithrombotic capabilities of a liposomal formulation, Zn-dipicolylamine cyanine-3[22,22]/1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (molar ratio, 3:97), designated as DPAL, which we previously described binds selectively to PS-enriched cell surfaces, compared with effects on bleeding, in mouse models.

Introduction: Pediatric extracorporeal membrane oxygenation (ECMO) management presents unique challenges in acute care settings, requiring specialized expertise to manage critically ill children. Medical and surgical fellows often manage these patients, but prior residency training rarely provides sufficient ECMO exposure. We developed and evaluated a multimodal pediatric ECMO boot camp for new fellows.

In the complex arena of Congenital Diaphragmatic Hernia (CDH) management, Extracorporeal Life Support (ECLS) provides a strategic window for stabilization and surgical correction, during which time marginal gains in patient stability can tip the scales towards survival. In modern neonatal ECLS, the focus is increasingly on minimizing survivor morbidity, which calls for considerable multidisciplinary expertise to enhance patient outcomes. This review will delve into the most up-to-date literature on the management of CDH in the context of ECLS, providing a comprehensive synthesis of current insights.

Dams and reservoirs are often needed to provide environmental water and maintain suitable water temperatures for downstream ecosystems. Here, we evaluate if water allocated to the environment, with storage to manage it, might allow environmental water to more reliably meet ecosystem objectives than a proportion of natural flow. We use a priority-based water balance operations model and a reservoir temperature model to evaluate 1) pass-through of a portion of reservoir inflow versus 2) allocating a portion of storage capacity and inflow for downstream flow and stream temperature objectives.

Benign ovarian lesions in the pediatric population have variable risk of recurrence or development of metachronous lesions, leading to variations in operative approach. Our study compares outcomes with differing surgical approaches to better elucidate risk of recurrent or metachronous lesions, time to development of these lesions, and hospital length of stay to determine if one operative approach has superior outcomes. We retrospectively examined data from Indiana University Health facilities from 2002 to 2020.

Article Synopsis
  • Lu-octreotate is an approved therapy for treating neuroendocrine tumors (NETs) but has drawbacks like fast pharmacokinetics and low imaging capability due to insufficient γ-emissions.
  • New compound [Cu]Cu-DOTA-Evans blue-TATE (EB-TATE) shows improved properties compared to Lu, like better therapeutic efficacy in preclinical studies conducted on NET models.
  • Preclinical tests demonstrated that [Cu]Cu-EB-TATE had higher tumor elimination rates and prolonged retention in tumors, along with acceptable dosimetry for potential human patients.

Introduction: While competency-based training is at the forefront of educational innovation in General Surgery, Pediatric Surgery training programs should not wait for downstream changes. There is currently no consensus on what it means for a pediatric surgery fellow to be "practice-ready". In this study, we aimed to provide a framework for better defining competency and practice readiness in a way that can support the Milestones system and allow for improved assessment of pediatric surgery fellows.

Introduction: Evidence-based medicine guides clinical decision-making; however, promoting enteral nutrition has historically followed a dogmatic approach in which patients graduate from clear liquids to full liquids to a regular diet after return of bowel function. Enhanced recovery after surgery has demonstrated that early enteral nutrition initiation is associated with shorter hospital stays. We aimed to understand postoperative pediatric nutrition practices in Kenya and the United States.

Since the early use of extracorporeal life support (ECLS), new innovations and technological advancements have augmented the ability to use this technology in children and neonates. Cannulae have been re-designed to maintain structure and allow for single cannula venovenous (VV) ECLS in smaller patients. Circuit technology, including pumps and tubing, has evolved to permit smaller priming volumes and lower flow rates with fewer thrombotic or hemolytic complications.

In neonates with cardiac and/or respiratory failure, extracorporeal membrane oxygenation (ECMO) continues to be an important method of respiratory and/or cardiovascular support where conventional treatments are failing. ECMO cannulation involves a complex decision-making process to choose the proper ECMO modality and cannulation strategy to match each patient's needs, unique anatomy, and potential complication profile. Initially, all ECMO support involved cannulating both the carotid artery and the internal jugular vein (IJV), known as veno-arterial (VA-ECMO) for cardiac and/or respiratory support.
