The acute respiratory distress syndrome (ARDS) is a proinflammatory condition that often complicates trauma and critical illness. Animal studies have shown that both gender and sex hormones play an important role in inflammatory regulation. Human data are scant regarding the role of gender and sex hormones in developing ARDS. Our objective was to describe gender and hormonal differences in patients who develop ARDS in a large cohort of critically injured adults. ⋯ Women are more likely than men to develop ARDS after critical injury. Despite the increased incidence in ARDS, the mortality in patients with ARDS does not differ according to gender. The inflammatory properties of sex hormones may contribute to ARDS, but they do not fully explain observed gender differences.

Comparative Study
Comparison of hospital mortality rates after burn injury in New York State: a risk-adjusted population-based observational study.
Severity-adjusted mortality is an unequivocal measure of burn care success. Hospitals can be compared on this metric using administrative data because information required for calculating statistically adjusted risk of mortality is routinely collected on hospital admission. ⋯ Administrative hospital discharge data are extensive and comparably enough collected to allow comparison of the performance of burn centers. Risk-adjusted models show that patients have statistically indistinguishable risk-adjusted odds of mortality regardless of which hospital in New York State cared for them.

The role of brain natriuretic peptide (BNP) after traumatic brain injury (TBI) remains unclear, and its relationship with hyponatremia is still controversial. The aim of this study is to investigate the secretion pattern of N-terminal (NT)-proBNP in patients with TBI and to assess the relationship between NT-proBNP, sodium balance, and intracranial pressure (ICP). ⋯ This study provides evidence that BNP plasma concentrations increase rapidly after TBI. Plasma BNP concentrations are correlated with hyponatremia in severe TBI patients but not in mild and moderate TBI patients. Furthermore, patients with elevated ICP have a higher serum BNP level in first 4 days after injury.

In-hospital mortality and surgical utilization in severely polytraumatized patients with and without spinal injury.
Patients who sustain major trauma experience multisystem injuries including those affecting the spine. We hypothesize that recovery after spinal injuries differs from those affecting other systems. The purpose of our study was to compare in-hospital mortality and surgical resource utilization in severely polytraumatized patient with and without spinal injury. ⋯ In this study, we conclude that the presence of a spinal injury in the setting of severe polytrauma (ISS>15) is associated with a prolonged course of ventilatory support, ICU, and in-hospital LOS. Trauma hospitals treating patients with spinal fracture should be aware of differences in the use of health services for this patient population.

Tachycardia is an important early sign of shock in trauma. Although the base deficit (BD) and lactate are indicative of hypoperfusion and known to predict mortality, some cases show a discrepancy between heart rate (HR) and BD or lactate; such cases have poor prognosis. The objective of this study was to examine whether lack of tachycardia after hypoperfusion is associated with increased mortality. ⋯ The lack of tachycardia in the presence of hypoperfusion is associated with poor prognosis independent of injury severity, SBP, and head injury. A discrepancy between HR and indicators of hypoperfusion could be considered as a predictor of mortality in trauma patients.
