Chronic obstructive respiratory disorders (ORDs) are linked to increased rates of cancer-related deaths. Little is known about the effects of hypercapnia (elevated CO2) on development of pancreatic ductal adenocarcinoma (PDAC) and drug resistance. ⋯ PDAC cells exposed to hypercapnic environments, which is common in patients with ORD, showed tumor proliferation, radioresistance, and chemoresistance. Patients with a history of ORD had a worse overall prognosis, suggesting that hypercapnic conditions play a role in the development and progression of PDAC and stressing the need for patient-tailored care.

Occult hypoperfusion (OH), or global hypoperfusion with normal vital signs, is a risk factor for poor outcomes in elderly trauma patients. We hypothesized that OH is associated with worse outcomes than shock in both young and elderly trauma patients. ⋯ In elderly but not younger patients, OH is associated with worse outcomes than shock. Although shock parameters might need to be redefined in elderly patients, more attention is necessary for the diagnosis and treatment of all hypoperfused states in this age group.

We aimed to assess patient and demographic factors, treatment trends, and survival outcomes of patients with colorectal cancer with metastasis to the liver, lung, or both sites. Differences remain among national guidelines about the optimal management strategy. ⋯ Patients with metastasis to lung had increased overall survival compared with other sites of metastases, regardless of treatment modality. Combined resection of primary tumor, metastasectomy, and chemotherapy appears to offer the greatest chance of survival.

Operating room (OR) cost accounts for a significant portion of inpatient spending, but most surgeons are unaware of the costs of OR implants and supplies. We leveraged behavioral economics principles and a cost transparency tool to have an impact on discretionary OR spending (disposable supplies). ⋯ Deployment of a cost feedback tool using behavioral economics principles resulted in a significant decrease in OR spending without negatively affecting complication rate.

Gun violence remains a significant public health problem that is both understudied and underfunded, and plagued by inadequate or inaccessible data sources. Over the years, numerous trauma centers have attempted to use local registries to study single-institutional trends, however, this approach limits generalizability to our national epidemic. In fact, even easily accessible, health-centered data from the CDC lack national relevance because they are limited to those enrolled states only. We sought to examine how publicly available law enforcement data from all 50 states might complement our understanding of circumstances and demographics surrounding national firearm death and help forge the first step in partnering law enforcement with trauma centers. ⋯ Gun violence represents an ongoing public health concern, with the proportion of firearm homicide steadily and significantly increasing from 1980 to 2016. Homicide data from the Federal Bureau of Investigation can serve to supplement trauma registry data by helping to define gun violence patterns. However, stronger partnerships between local law enforcement agencies and trauma centers are necessary to better characterize firearm type and resultant injury patterns, direct prevention efforts and firearm policy, and reduce gun-related deaths.
