BackgroundThe incarceration of a segment of bowel within a groin hernia can result in intestinal strangulation if hernia treatment is delayed. Once intestinal strangulation occurs, a bowel resection may be required, and there is an overall increased risk for postoperative complications. The aim of this study was to identify biomarkers to predict the severity of an incarcerated groin hernia.Material/MethodsWe retrospectively evaluated the records of 95 patients with incarcerated groin hernias who underwent emergency surgical correction of the hernias. The need for a bowel resection was regarded as an indicator of severity in incarcerated groin hernia patients. The patients were divided into 2 groups: patients with bowel resection surgery and patients without bowel resection surgery.ResultsWe discovered that leukocyte count (leukocyte count ≥10×103/mm3), neutrophil-to-lymphocyte ratio (NLR, NLR ≥11.5), presentation of bowel obstruction, and duration of incarceration (duration of incarceration ≥26 h) were significantly associated with bowel resection in incarcerated groin hernia patients by using the chi-square test. Factors such as leukocyte count, NLR, presentation of bowel obstruction, and duration of incarceration were analyzed using multivariate logistic regression analysis. We found that NLR, presentation of bowel obstruction, and duration of incarceration were independently and significantly related to bowel resection in incarcerated groin hernia patients.ConclusionsAn elevated NLR can serve as a biomarker for the prediction of severity of incarcerated groin hernias. Additionally, incarcerated groin hernia patients who present with bowel obstruction or with duration of intestinal incarceration longer than 26 h have an increased risk for bowel resection.
End stage renal disease (ESRD) is a progressive loss of kidney function with a high rate of morbidity and mortality. Transplantable organs are hard to come by and hold a high risk of recipient immune rejection. We intended to establish a more effective and faster method to decellularize and recellularize the kidney scaffold for transplant and regeneration. We successfully produced renal scaffolds by decellularizing rat kidneys with 0.5% sodium dodecyl sulfate (SDS), while still preserving the extracellular matrix (ECM) 3D architecture, an intact vascular tree and biochemical components. We recellularized the kidney scaffolds with mouse embryonic stem (ES) cells that then populated and proliferated within the glomerular, vascular, and tubular structures. After in vivo implantation, these recellularized scaffolds were easily reperfused, tolerated blood pressure and produced urine with no blood leakage. Our methods can successfully decellularize and recellularize rat kidneys to produce functional renal ECM scaffolds. These scaffolds maintain their basic components, retain intact vasculature and show promise for kidney regeneration.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
