We undertook the current study to determine the impact of elevated admission systolic blood pressure (SBP) on trauma patients without severe brain injury. ⋯ The admission SBP thresholds that predicted higher mortality for the young and middle-aged were >190 mm Hg and >180 mm Hg, respectively. Elderly trauma patients tolerated higher admission SBP than their younger counterparts and multiple elevated SBP thresholds were associated with significantly reduced mortality in the elderly.

The biologic mechanisms by which laparoscopic antireflux surgery (LARS) might influence the inflammatory process leading to bronchiolitis obliterans syndrome are unknown. We hypothesized that LARS alters the pulmonary immune profile in lung transplant patients with gastroesophageal reflux disease. ⋯ Our preliminary study has demonstrated that LARS can restore the physiologic balance of pulmonary leukocyte populations and that the BALF concentration of pro-inflammatory mediators is altered early after LARS. These results suggest that LARS could modulate the pulmonary inflammatory milieu in lung transplant patients with gastroesophageal reflux disease.

The objective of this study was to evaluate the efficacy of resuscitative endovascular aortic balloon occlusion (REBOA) of the distal aorta in a porcine model of pelvic hemorrhage. ⋯ Balloon occlusion of the aorta is an effective method to control pelvic arterial hemorrhage. This technique should be further developed as an adjunct to manage noncompressible pelvic hemorrhage.

Approximately 12% of operations for traumatic neuropathy are for patients with segmental nerve loss, and less than 50% of these injuries obtain meaningful functional recovery. Polyethylene glycol (PEG) therapy has been shown to improve functional outcomes after nerve severance, and we hypothesized this therapy could also benefit nerve autografting. ⋯ Polyethylene glycol therapy improves early physiologic function, behavioral outcomes, and distal axonal density after nerve autografting.

Sleep deprivation, common in intensive care unit (ICU) patients, may be associated with increased morbidity and/or mortality. We previously demonstrated that significant numbers of nocturnal nursing interactions (NNIs) occur during the routine care of surgical ICU patients. For this study, we assessed the quantity and type of NNIs in different ICU types: medical, surgical, cardiothoracic, pediatric, and neonatal. We hypothesized that the number and type of NNIs vary among different ICU types. ⋯ NNIs occur frequently and vary across different ICU types. Many NNIs are due to nursing assessment and patient care activities, much of which could be safely omitted or clustered. A protocol for nocturnal sleep promotion is warranted in order to standardize ICU NNIs and minimize nighttime sleep disruptions.
