Impact of trauma center designation in pediatric renal trauma: National Trauma Data Bank analysis.

Introduction: The pediatric kidney is the most common urinary tract organ injured in blunt abdominal trauma. Trauma care in the United States has been established into a hierarchical system verified by the American College of Surgeons (ACS). Literature evaluating management of pediatric renal trauma across trauma tier designations is scarce.

Recent innovations and trends in in-conduit hydropower technologies and their applications in water distribution systems.

Water conduits have a large untapped potential to recapture energy for small hydroelectric generation, which can substantially reduce grid electricity consumption and/or provide renewable energy to water agencies. Over the past decade, there has been a recent technological renaissance in off-the-shelf "water-to-wire" turbine technologies including reaction, impulse, and hydrokinetic turbines that target the sub 1-MW in-conduit hydroelectric market. However, adoption of small hydropower technologies remain limited in water and wastewater utility sector, possibly due to the lack of market penetration and exposure.

Cryopreserved human amniotic membrane and a bioinspired underwater adhesive to seal and promote healing of iatrogenic fetal membrane defect sites.

Introduction: We investigated the ability of cryopreserved human amniotic membrane (hAM) scaffold sealed with an underwater adhesive, bio-inspired by marine sandcastle worms to promote healing of iatrogenic fetal membrane defects in a pregnant swine model.

Methods: Twelve Yucatan miniature pigs underwent laparotomy under general anesthesia at 70 days gestation (term = 114 days). The gestational sacs were assigned to uninstrumented (n = 24) and instrumented with 12 Fr trocar, which was further randomized into four different arms-no hAM patch, (n = 22), hAM patch secured with suture (n = 16), hAM patch with no suture (n = 14), and hAM patch secured with adhesive (n = 9).

Best practices for performing experimental surgery in swine.

The authors have extensive experience in surgery, anesthesia, and perioperative care in both miniature and domestic swine in the research setting. This manuscript describes the techniques that have been developed over the last four decades while developing porcine surgical models and their use in translational research. Swine are conditioned and socialized during a seven-day period prior to entering into a survival surgical protocol.

Animal models of toxicology testing: the role of pigs.

Introduction: In regulatory toxicological testing, both a rodent and non-rodent species are required. Historically, dogs and non-human primates (NHP) have been the species of choice of the non-rodent portion of testing. The pig is an appropriate option for these tests based on metabolic pathways utilized in xenobiotic biotransformation.
