This study aims to identify modifiable factors related to firearm homicide (FH). ⋯ The causes and potential solutions to FH are complex and closely tied to public policy. Our data suggests that certain types of socioeconomic support and firearm restrictive legislation should be emphasized in efforts to reduce firearm deaths in America.

This study aimed to validate the prognostic significance of stratification using pathological stage and response to neoadjuvant chemotherapy with a nationwide database from an authorized institute by the Japan Esophageal Society. ⋯ The prognostic value of classification using pStage and the pathological response was successfully validated using real-world data in Japan. This result would guide appropriate treatment for patients with esophageal squamous cell carcinoma who received neoadjuvant chemotherapy followed by esophagectomy.

The pathogenesis of lung hypoplasia in congenital diaphragmatic hernia (CDH), a common birth defect, is poorly understood. The diaphragmatic defect can be repaired surgically, but the abnormal lung development contributes to a high mortality in these patients. To understand the underlying pathobiology, we compared the proteomic profiles of fetal rat lungs at the alveolar stage (E21) that were either exposed to nitrofen in utero (CDH lungs, n=5) or exposed to vehicle only (non-CDH control lungs, n=5). ⋯ STAT3 inhibition after direct nitrofen exposure to fetal rat lung explants (E14.5) partially rescued the hypoplastic lung phenotype ex vivo by increasing peripheral lung budding. Moreover, we demonstrated that several STAT3-associated cytokines (IL-15, IL-9, andIL-2) are increased in fetal tracheal aspirates of CDH survivors compared with nonsurvivors after fetoscopic endoluminal tracheal occlusion. With our unbiased proteomics approach, we showed for the first time that downstream inflammatory processes are likely involved in the pathogenesis of abnormal lung development in CDH.

To assess outcomes of fenestrated-branched endovascular aortic repair (FB-EVAR) of Extent I-III thoracoabdominal aortic aneurysms (TAAAs) without prophylactic cerebrospinal fluid drainage (CSFD). ⋯ FB-EVAR of Extent I-III TAAAs without CSFD has low mortality and low rates of permanent paraplegia (2%). SCI occurred in 8% of patients, and rescue treatment improved symptoms in 73% of them.

To explore how surgery residents cope with unwanted patient outcomes including postoperative complications and death. ⋯ In this novel qualitative study, general surgery residents described the coping strategies that they organically used after postoperative complications and deaths. To improve resident well-being, it is critical to first understand the natural coping processes. Such efforts will facilitate structuring future support systems to aid residents during these difficult periods.
