We demonstrate a role for the NAD-dependent deacetylase Sirt1 in the regulation of autophagy. In particular, transient increased expression of Sirt1 is sufficient to stimulate basal rates of autophagy. In addition, we show that Sirt1(-/-) mouse embryonic fibroblasts do not fully activate autophagy under starved conditions. Reconstitution with wild-type but(More)
BACKGROUND Laparoscopic adjustable gastric banding (LAGB) is a proven method for achieving long-term weight loss, but there has been controversy regarding how pay status impacts outcomes after surgery. OBJECTIVES To compare outcomes of LAGB with respect to percentage excess weight loss (%EWL), perioperative complications, and number of band adjustments(More)
The feeding of human milk (milk from the infant's own mother; excluding donor milk) during the newborn intensive care unit (NICU) stay reduces the risk of costly and handicapping morbidities in premature infants. The mechanisms by which human milk provides this protection are varied and synergistic, and appear to change over the course of the NICU stay. The(More)
BACKGROUND Over the last decade, our institution has experienced a relative increase in the number of mundane cases, such as appendectomy and incision and drainage of abscess, versus index (complex) cases. We sought to determine if this trend is present at the national level. METHODS A retrospective review of surgical case volume at 36 freestanding(More)
Since the introduction of robotic surgery in children in 2001, it has been employed by select pediatric laparoscopic surgeons, but not to the degree of adult surgical specialists. It has been suggested that the technical capabilities of the robot may be ideal for complex pediatric surgical cases that require intricate dissection. However, due to the size(More)
PURPOSE Although recurrence remains one of the most feared complications following congenital diaphragmatic hernia (CDH) repair, there are minimal data on the optimal surgical approach to these complex situations. The purpose of this study was to survey the international pediatric surgery community to ascertain practice patterns for both minimally invasive(More)
When performing an open duodenal web excision, it is helpful to identify the web using a nasogastric tube because it is often difficult to determine where the web origin is located when looking at the serosal side of the bowel. However, it may be challenging to navigate the nasogastric tube to the web during laparoscopy. We present a novel technique that(More)
PURPOSE Although surgical residency training is a structured, regulated system for surgical skill acquisition, after residency or fellowship, no good method exists for practicing surgeons to learn new, developing techniques. Because 1-2-day simulation courses are probably inadequate for teaching a new technique and because it is often unrealistic for a(More)
PURPOSE While adult bowel anastomoses are typically performed with staplers, neonatal small bowel anastomoses have traditionally been performed in a hand-sewn manner due to the large size of surgical staplers. The purpose of this study was to compare stapled anastomosis using a newly available, 5-mm laparoscopic stapler to a hand-sewn anastomosis in an open(More)
