Common and external iliac artery injuries (IAI) portend significant morbidity and mortality. The goal of this study was to examine the impact of mechanism of injury and type of repair on outcomes and identify the optimal repair for patients with traumatic IAI using a large, national dataset. ⋯ Traumatic IAI causes significant morbidity and mortality. Endovascular repair was identified as the only modifiable predictor of decreased mortality in blunt-injured patients with traumatic IAI. Therefore, for select patients with blunt IAIs, an endovascular repair should be the preferred approach.

Use of whole-body CT scan (WBCT) is widespread in the evaluation of traumatically injured patients and may be associated with improved survival. WBCT protocols include the use of IV contrast unless there is a contraindication. This study tests the hypothesis that using plain WBCT scan during the global contrast shortage would result in greater need for repeat contrast-enhanced CT, but would not impact mortality, missed injuries, or rates of acute kidney injury (AKI). ⋯ Trauma imaging practices at our center changed during the global contrast shortage; the use of contrast decreased despite the frequency of trauma WBCT scans remaining the same. The rates of AKI and RRT did not change, suggesting that WBCT with contrast is insufficient to cause AKI. The missed injury rate was equivalent. Our data suggest similar outcomes can be achieved with selective IV contrast use during WBCT.

Chronic pancreatitis is a debilitating, life-altering disease; however, the long-term outcomes after operative intervention have not been established. ⋯ Our results represent the largest series to date evaluating long-term survival outcomes in patients with chronic pancreatitis after operative intervention. Our data give insight into the cause of death and allow for the development of mitigation strategies and long-term monitoring of comorbid conditions.

Medicaid expansion impacted patients when assessed at a national level. However, of the 32 states that expanded Medicaid, only three were Southern states. Whether results apply to Southern states that share similar geopolitical perspectives remains elusive. We aimed to assess the impact of Medicaid expansion on breast cancer diagnosis and treatment in 8 Southern states in the US. ⋯ Unlike NMES, MES experienced increased Medicaid insured, increased treatment, and decreased distant-stage disease at diagnosis. Medicaid expansion in the South leads to earlier and more comprehensive treatment of breast cancer.

Pancreatic ductal adenocarcinoma (PDAC) is an aggressive and lethal cancer. Hypercapnic tumor microenvironments were previously shown to promote cancer chemoresistance. In this study, we aimed to investigate the impact of tissue hypercapnia on PDAC prognosis. ⋯ The pancreatic tumor microenvironment plays an integral role in tumor aggressiveness, and our previous in vitro data suggest that hypercapnia promotes an aggressive, more resistant phenotype. Herein, we show that in early-stage pancreatic cancer, hypercapnic tissue signatures corresponded with a worse overall survival.
