Current blunt cerebrovascular injury (BCVI) grading grossly differentiates injury characteristics such as luminal stenosis (LS) and aneurysmal disease. The effect of increasing degree of LS beyond the current BCVI grading scale on stroke formation is unknown. ⋯ Higher percentage LS beyond the currently used BCVI grading scale has a non-significantly increased rate of stroke in both aneurysmal and non-aneurysmal BCVI. Grade 3 BCVI with PSA and LS seems to be a high-risk subgroup. Use of EI confounds modern measurement of stroke risk in higher LS BCVI.

Multicenter Study Observational Study
Open abdomen and entero-atmospheric fistulae: An interim analysis from the International Register of Open Abdomen (IROA).
No definitive data describing associations between cases of Open Abdomen (OA) and Entero-atmospheric fistulae (EAF) exist. The World Society of Emergency Surgery (WSES) and the Panamerican Trauma Society (PTS) thus analyzed the International Register of Open Abdomen (IROA) to assess this question. ⋯ Entero-atmospheric fistulas are influenced by the duration of open abdomen treatment and by the nutritional status of the patient. Peritonitis, intestinal anastomosis, negative pressure and oral or enteral nutrition were not risk factors for EAF during OA treatment.

Abdominal vascular injuries (AVIs) remain a great challenge since they are associated with significant mortality. Penetrating injury is the most common cause of AVIs; however, some AVI series had more blunt injuries. There is little information regarding differences between penetrating and blunt AVIs. The objective of the present study was to identify the differences between these two mechanisms in civilian AVI patients in terms of patient's characteristics, injury details, and outcomes. ⋯ Blunt AVI patients had higher ISS and more internal iliac artery injuries, while penetrating AVI patients had more aortic injuries and vena cava injuries. Majority of AVI patients in both groups presented with shock and required DCS.

Chest trauma and obesity are both associated with increased risks for respiratory complications (e.g. hypoxia, hypercarbia, pneumonia), which are frequent causes of posttraumatic morbidity and mortality. However, as there is only limited and inconsistent evidence, the aim of our study was to analyse the effect of body mass index (BMI) on patient outcomes after thoracic trauma. ⋯ Obesity has a negative impact on outcomes after blunt chest trauma, as it is associated with prolonged duration of mechanical ventilation, ICU and hospital length of stay. Mortality did not seem to be affected, yet, further research is required to confirm these results in a larger cohort.

Observational Study
Differences in trauma mortality between ACS-verified and state-designated trauma centers in the US.
Traumatic injury is a leading cause of deaths worldwide, and designated trauma centers are crucial to preventing these. In the US, trauma centers can be designated as level I-IV by states and/or the American College of Surgeons (ACS), reflecting the resources available for care. We examined whether state- and ACS-verified facilities of the same level (I-IV) had differences in mortality, complications, and disposition, and whether differences varied by center level. ⋯ Findings suggest that while outcomes are similar between ACS-verified and state-designated Level I and II centers, state-designated Level III and particularly Level IV centers show poorer outcomes relative to their ACS-verified counterparts. Further research could explore mechanisms for these differences, or inform potential changes to state designation processes for lower-level centers.
