Background Existing evidence for disparities in inflammatory bowel disease is fragmented and heterogenous. Underlying mechanisms for differences in outcomes based on race and socioeconomic status remain undefined. We performed a systematic review of the literature to examine disparities in surgery for inflammatory bowel disease in the United States. Methods Electronic databases were searched from 2000 through June 11, 2021, to identify studies addressing disparities in surgical treatment for adults with inflammatory bowel disease. Eligible English-language publications comparing the use or outcomes of surgery by racial/ethnic, socioeconomic, geographic, and/or institutional factors were included. Studies were grouped according to whether outcomes of surgery were reported or surgery itself was the relevant end point (utilization). Quality was assessed using the Newcastle-Ottawa Scale for observational studies. Results Forty-five studies were included. Twenty-four reported surgical outcomes and 21 addressed utilization. Race/ethnicity was considered in 96% of studies, socioeconomic status in 44%, geographic factors in 27%, and hospital/surgeon factors in 22%. Although study populations and end points were heterogeneous, Black and Hispanic patients were less likely to undergo abdominal surgery when hospitalized; they were more likely to have a complication when they did have surgery. Differences based on race were correlated with socioeconomic factors but frequently remained significant after adjustments for insurance and baseline health. Conclusions Surgical disparities based on sociologic and structural factors reflect unidentified differences in multidisciplinary disease management. A broad, multidimensional approach to disparities research with more granular and diverse data sources is needed to improve health care quality and equity for inflammatory bowel disease.

Vasoplegic syndrome is a form of vasodilatory shock that occurs frequently in patients who undergo cardiac surgery requiring cardiopulmonary bypass (CBP). Treatment often demands high doses of vasopressors over sustained periods for hypotension that can be refractory to standard vasoactive medications. Furthermore, the development of vasoplegia greatly contributes to morbidity and mortality following cardiac surgery. Methylene blue (MB) has become a popular therapy for cardiac vasoplegia despite a paucity of prospective data to direct its use. Therefore, the aim of this study was to review available data regarding mechanisms, dosing strategies, and side effects of MB, with a focus on its applications for vasoplegia in cardiac surgery.

The pulmonary-systemic ratio is more strongly associated with risk-adjusted morbidity and mortality in valve surgery than pulmonary arterial pressure. By integrating ventricular interactions, this metric may better characterize the risk of valve surgery.

Medical therapy for mycotic aortic aneurysms (MAA) is almost universally fatal, while surgical and endovascular repair carry high morbidity and mortality. The purpose of this study was to compare outcomes between patients receiving treatment for MAA. Records were obtained and patients with MAA were stratified by intervention: endovascular repair, open surgery, and medical therapy. Primary outcomes were aneurysm-related mortality and survival. Risk-adjusted associations with mortality were assessed using time-to-event analysis. Thirty-eight patients were identified (median age, 67). Twenty-one underwent endovascular repair,10 had open surgery and 7 received medical therapy alone. Overall mortality was 47% (n = 18), with 94% aneurysm related. Median survival was significantly longer in the endovascular group (747.0 [161-1249]) vs open surgery and medical therapy (507.5 [34-806] and 66 [13-146] days, respectively; P = .02). The endovascular group had significantly fewer perioperative complications (43% vs 80%, P < .01). However, 4 endovascular patients experienced reinfection versus no open surgery patients. Mortality risk factors included medical therapy (hazard ratio [HR]: 5.3, P < .01) and aneurysm size (HR: 1.4 per 1-cm increase in diameter, P = .03). Endovascular repair of MAA was associated with the best long-term survival and lowest perioperative complication rate, although it is associated with greater reinfection. These tradeoffs should be considered when selecting which procedure is best for a patient.
