Inflammatory bowel disease (IBD) appears to be an inappropriate response to an antigen that leads to chronic inflammation rather than repair. This review looks at the role of endothelin-1 (ET-1) as a proinflammatory agent in IBD. ET-1 antagonists in animal models reduce the incidence and severity of IBD. These antagonists may be useful for treatment of IBD in humans. [ABSTRACT FROM AUTHOR]

The incremental benefit of emergency medical services (EMS) activation of the cardiac catheterization laboratory (CCL) for ST-elevation myocardial infarction (STEMI) in the setting of an established in-house interventional team (IHIT) is uncertain. We evaluated the impact of EMS activation on door-to-balloon (D2B) time and first medical contact-to-balloon (FMC2B) time for STEMI when coupled with a 24-hour/day IHIT. All patients presenting with STEMI to Loyola University Medical Center had demographic, procedural, and outcome data consecutively entered in a STEMI Data Registry. From 223 consecutive patients presenting between April 2009 and December 2015, a retrospective analysis was performed on 190 patients. Patients were divided into 2 groups depending on CCL activation mode (EMS activation or emergency department activation) and STEMI treatment process times were compared. The primary end point was D2B process times. The secondary end point was FMC2B process times in a subgroup analysis of EMS-transported patients. D2B times were shorter (37 ± 14 minutes vs 57 ± 27 minutes, p < 0.001) with EMS activation. Subgroup analysis of EMS-transported patients demonstrated shorter FMC2B times with EMS activation (52 ± 17 minutes vs 67 ± 32 minutes, p = 0.002). EMS activation was the only predictor of D2B ≤60 minutes in multivariable analysis of EMS-transported patients (odds ratio 9.4; 95% confidence interval 2.1 to 43.0; p = 0.04). In conclusion, EMS activation of the CCL in STEMI was associated with significant improvements in already excellent D2B and FMC2B times even in the setting of a 24-hour/day IHIT., (Copyright © 2019 Elsevier Inc.
