Contemporary Ethical Considerations for Pediatric Metabolic and Bariatric Surgery.

Background: The prevalence of pediatric obesity continues to increase dramatically. Though metabolic and bariatric surgery (MBS) is efficacious and is supported by high-quality data in this population, it remains underutilized. This paper aims to discuss current ethical concerns, considerations, and controversies of pediatric MBS.

In Vivo Deformation of the Human Basilar Artery.

An estimated 6.8 million people in the United States have an unruptured intracranial aneurysms, with approximately 30,000 people suffering from intracranial aneurysms rupture each year. Despite the development of population-based scores to evaluate the risk of rupture, retrospective analyses have suggested the limited usage of these scores in guiding clinical decision-making.

Pancreatic masses in children: a single-center experience over two decades.

Unlabelled: Pancreatic masses are extremely rare in pediatric patients, with limited data available. This lack of data makes the diagnosis and management of these tumors in children extremely challenging. Therefore, we aimed to describe the presentations, clinical course, and outcomes of children with pancreatic tumors at our center.

Breath-by-breath assessment of acute pulmonary edema using electrical impedance tomography, spirometry and volumetric capnography in a sheep () model.

Background: The bedside diagnosis of acute pulmonary edema is challenging. This study evaluated the breath-by-breath information from electrical impedance tomography (EIT), respiratory mechanics and volumetric capnography (VCap) to assess acute pulmonary edema induced by xylazine administration in anesthetized sheep.

Objective: To determine the ability and efficiency of each monitoring modality in detecting changes in lung function associated with onset of pulmonary edema.

A Mathematical Model for Postimplant Collagen Remodeling in an Autologous Engineered Pulmonary Arterial Conduit.

This study was undertaken to develop a mathematical model of the long-term in vivo remodeling processes in postimplanted pulmonary artery (PA) conduits. Experimental results from two extant ovine in vivo studies, wherein polyglycolic-acid (PGA)/poly-L-lactic acid tubular conduits were constructed, cell seeded, incubated for 4 weeks, and then implanted in mature sheep to obtain the remodeling data for up to two years. Explanted conduit analysis included detailed novel structural and mechanical studies.
