Ethnic disparities in pediatric appendicitis: the impact of hispanic ethnicity on presentation, complications, and postoperative outcomes

PURPOSE

Our study investigates ethnic disparities in pediatric appendicitis, focusing on the impact of Hispanic ethnicity on presentation, complications, and postoperative outcomes.

METHODS

We conducted a retrospective analysis of pediatric patients undergoing appendectomy for acute appendicitis from 2015 to 2020 using the National Surgical Quality Improvement Program-Pediatric database. We compared 30-day postoperative complications, postoperative length of stay, and postoperative interventions between Hispanic and non-Hispanic White patients.

RESULTS

65,976 patients were included, of which 23,462 (35.56%) were Hispanic and 42,514 (64.44%) non-Hispanic White. Hispanic children were more likely to present to the hospital with complicated appendicitis (31.75% vs. 25.15%, P < 0.0001) and sepsis (25.22% vs. 19.02%, P < 0.0001) compared to non-Hispanic White. Hispanics had higher rates of serious complications (4.06% vs. 3.55%, P = 0.001) but not overall complications (5.37% vs. 5.09%, P = 0.12). However, after multivariate analysis, Hispanic ethnicity was not associated with an increased rate of serious postoperative complications (OR 0.93, CI 0.85-1.01, P = 0.088); it was associated with less overall complications (OR 0.88, CI 0.81-0.96, P = 0.003) but a longer postoperative length of stay (OR 1.09, CI 1.04-1.14, P < 0.0001).

CONCLUSION

Hispanic children are more likely to present with complicated appendicitis, contributing to increased postoperative complications. Notably, upon adjustment for the impact of complicated appendicitis, our findings suggest potentially favorable outcomes for Hispanic ethnicity. This emphasizes the need to understand delays in presentation to improve outcomes in the Hispanic population.

Anti-fibrotic activity of a rho-kinase inhibitor restores outflow function and intraocular pressure homeostasis

Glucocorticoids are widely used as an ophthalmic medication. A common, sight-threatening adverse event of glucocorticoid usage is ocular hypertension, caused by dysfunction of the conventional outflow pathway. We report that netarsudil, a rho-kinase inhibitor, decreased glucocorticoid-induced ocular hypertension in patients whose intraocular pressures were poorly controlled by standard medications. Mechanistic studies in our established mouse model of glucocorticoid-induced ocular hypertension show that netarsudil both prevented and reduced intraocular pressure elevation. Further, netarsudil attenuated characteristic steroid-induced pathologies as assessed by quantification of outflow function and tissue stiffness, and morphological and immunohistochemical indicators of tissue fibrosis. Thus, rho-kinase inhibitors act directly on conventional outflow cells to prevent or attenuate fibrotic disease processes in glucocorticoid-induced ocular hypertension in an immune-privileged environment. Moreover, these data motivate the need for a randomized prospective clinical study to determine whether netarsudil is indeed superior to first-line anti-glaucoma drugs in lowering steroid-induced ocular hypertension.
