J Trauma

Chest trauma frequently occurs in severely injured patients and is often associated with hemorrhagic shock. Immune dysfunction contributes to the adverse outcome of multiple injuries. The aims of this study were to establish a combined model of lung contusion and hemorrhage and to evaluate the cardiopulmonary and immunologic response. ⋯ Although physiologic readouts were selectively altered in response to the single or double hits, the combination did not uniformly augment the changes in inflammation. Our results suggest that the leading insult regarding the immunologic response is lung contusion, supporting the concept that lung contusion represents an important prognostic factor in multiple injuries.

Review Meta Analysis
Outcomes of proximal versus distal splenic artery embolization after trauma: a systematic review and meta-analysis.
The objective of this systematic review and meta-analysis was to assess the outcomes after angioembolization in blunt trauma patients with splenic injuries and to examine specifically the impact of the technique used. Studies evaluating adult trauma patients who sustained blunt splenic injuries managed by angioembolization were systematically evaluated. The following data were required for inclusion: grade of splenic injury, indication for embolization, and site of embolization (proximal [main splenic artery] or distal [selective]). ⋯ However, both techniques have an equivalent rate of infarctions and infections requiring splenectomy. Minor complications occur more often after distal embolization. This is primarily explained by the higher rate of segmental infarctions after distal embolization.

Comparative Study
Homicide, suicide, and unintentional firearm fatality: comparing the United States with other high-income countries, 2003.
Violent death is a major public health problem in the United States and throughout the world. ⋯ The United States has far higher rates of firearm deaths-firearm homicides, firearm suicides, and unintentional firearm deaths compared with other high-income countries. The US overall suicide rate is not out of line with these countries, but the United States is an outlier in terms of our overall homicide rate.
