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.

Few data are available describing the benefits of initiating fundamentals of laparoscopic surgery (FLS) training during medical school. We hypothesized that an intense 1-month surgical skills elective that included FLS task training for fourth-year medical students (MS4s) would result in performance levels indistinguishable from graduating chief residents (PGY5) who had received clinical skill training and access to self-guided FLS curriculum. ⋯ Incorporating FLS training into a 1 month-long medical school surgery elective enabled MS4s to achieve FLS performance similar to, or better than, the performance achieved by PGY5 surgery residents. We support the integration of FLS skills task training as a standard part of the skills training curriculum for medical students.

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.

Combat Gauze (CG) is currently the most widely used hemostatic dressing in combat. The testing of CG was initially performed in healthy and physiologically normal animals. The goal this study was to assess the efficacy in a model of severe acidosis and coagulopathy. ⋯ Combat Gauze significantly outperforms standard gauze dressings in a model of major vascular hemorrhage in acidotic and coagulopathic conditions. This effect appears to result from a decreased time lag between activation and first detectable clotting. Combat Gauze appears to maintain its efficacy even in the setting of severe acidosis and coagulopathy for the control of hemorrhage from vascular injury.

Although modern therapy for anal canal cancer typically consists of combined chemoradiation therapy (CRT), surgery remains an option for patients with small lesions, for palliative purposes, and for failure of nonoperative management. This study assesses the short-term outcomes of surgical management for epidermoid carcinoma of the anal canal using a large nationwide database. ⋯ Surgical intervention for anal canal cancer remains a necessary option for select patients. Morbidity rates vary significantly based on the type of treatment; operative approach is the primary factor associated with postoperative short-term complications. When surgery is required, recent CRT is not associated with a higher complication rate. With proper perioperative care and surgical technique, mortality rates remain low, and the increased death rate with diversion, even in the short term, likely represents advanced disease.
