Blast-related traumatic brain injuries have been common in the Iraq and Afghanistan wars, but fundamental questions about nature of these remain unanswered.
Importance Active surveillance (AS) is endorsed by clinical guidelines as the preferred management strategy for low-risk prostate cancer, but its use in contemporary practice remains incompletely defined. Objective To characterize trends over time and practice- practitioner-level variation of AS a large, national disease registry. Design, Setting, Participants This retrospective analysis prospective cohort study included men with defined prostate-specific antigen (PSA) less than 10 ng/mL,...
Incomplete or delayed fasciotomies are associated with muscle necrosis and death in civilian trauma. Combat explosions severely damage tissue distort normal anatomy making challenging. Rapid air evacuation may delay treatment of patients evolving extremity compartment syndrome. We investigated the impact fasciotomy revision release on combat casualties after evacuation.A retrospective review was performed who underwent Iraq, Afghanistan, at Landstuhl Regional Medical Center between January...
Fundamental questions remain unanswered about the longitudinal impact of blast-plus-impact complex traumatic brain injuries (TBI) from wars in Iraq and Afghanistan. This prospective, observational study investigated measures clinical outcome US military personnel evacuated to Landstuhl Regional Medical Center (LRMC) Germany after such "blast-plus" concussive TBIs. Glasgow Outcome Scale-Extended assessments completed 6–12 months injury indicated a moderate overall disability 41/47 (87%)...
When traditional vascular access methods fail, emergency through the intraosseous (IO) route can be lifesaving. Fluids, medications, and blood components have all been delivered these devices. We sought to compare performance of IO devices placed in sternum, humeral head, proximal tibia using a fresh human cadaver model.Commercially available infusion were into cadavers: sternum (FAST-1), head (EZ-IO), (EZ-IO). Sequentially, volume 0.9% saline infused each site under 300 mm Hg pressure over...
Background: Critical Care Air Transport Teams (CCATTs) are an integral component of modern casualty care, allowing early transport critically ill and injured patients. Aeromedical evacuation patients with significant pulmonary impairment is sometimes beyond the scope CCATT because limitations ventilator potential for further respiratory deterioration in flight. The Acute Lung Rescue Team (ALRT) was developed to facilitate these out combat theater. Methods: United States TRANSCOM Regulation...
Rhabdomyolysis has been associated with poor outcomes in patients traumatic injury, especially the setting of acute kidney injury (AKI). However, rhabdomyolysis not systematically examined a large cohort combat casualties injured wars Iraq and Afghanistan.We conducted retrospective study during operations Afghanistan who were initially admitted to intensive care unit from February 1, 2002, 2011. Information on age, sex, Abbreviated Injury Scale (AIS) score, Severity Score (ISS), mechanism...
Objective: The objective of this study was to assess the feasibility utilizing negative pressure wound therapy (NPWT) for treatment wartime soft-tissue wounds during intercontinental aeromedical evacuation. Background: Attempts use NPWT early phases overseas contingency operations resulted in occasional vacuum system failures and potentially contributed complications. These anecdotal episodes led a perception that evacuation carried high risk complications limited its use. As result, not...
Background: The success of US Air Force Critical Care Transport Teams (CCATT) in transporting critically ill and injured patients enabled changes military medical force deployment casualty care practice. Even so, a subset casualties remains who exceed even CCATT capabilities for movement. These led to the creation Landstuhl Acute Lung Rescue Team (ALeRT) close "care air" capability gap. Methods: ALeRT Registry was queried period between November 1, 2005, June 30, 2010. Additionally, Regional...
Critical Care Air Transport Teams (CCATTs) have evolved as a vital component of the U.S. Force's aeromedical evacuation system. Previous epidemiological research in this area is limited. The objective commentary to highlight importance obtaining robust data regarding patients transported by CCATTs. A limited analysis was performed describe CCATT during Operation Enduring Freedom and waning months Iraqi Freedom. transports for calendar year 2011 were examined recorded Transportation Command...
Rhabdomyolysis is a recognized complication of traumatic injury. The correlation an elevated creatine kinase (CK) level and the development acute kidney injury (AKI) has been studied in civilian population. We sought to review prevalence rhabdomyolysis injured war fighters determine if peak CK levels correlate with AKI.This retrospective cohort study patients admitted at US military treatment facility from January November 2010. Inclusion criteria were active duty transported after...
To use robotic visible-light optical coherence tomography (vis-OCT) to study circumferential segmental Schlemm's canal (SC) anatomy in mice after topical pilocarpine administration. Anterior segment imaging using a vis-OCT maintain perpendicular laser illumination aimed at SC was performed. Sixteen were studied for repeatability testing and aqueous humor outflow (AHO) pathway response drug. Pharmaceutical-grade (1%; n = 5) or control artificial tears (n 9) given, performed before 15 minutes...
In 2008, we showed that incomplete or delayed extremity fasciotomies were associated with mortality and muscle necrosis in war casualties limb injury. Subsequently, developed an education program focused on surgeon knowledge gaps regarding the diagnosis of compartment syndrome prophylactic fasciotomy. The included educational alerts, classroom training, video instruction, a research publication. We compared casualty data before after implementation to determine whether altered...
Traumatic brain injury contributes significantly to military combat morbidity and mortality. No longer maintaining comprehensive medical care facilities throughout the world, US developed a worldwide trauma system making patient moving part of system. Life-saving interventions are performed early, essential is delivered at forward locations. Patients then proceed successively through increasingly capable levels culminating with arrival in US. Proper selection thorough mission preparation...
Background: Intracranial hypertension (ICH) and hyperthermia are common after traumatic brain injury (TBI) associated with worse neurological outcomes. This study sets out to determine the combined power of temperature intracranial pressure (ICP) for predicting neurologic outcomes prolonged length stay (LOS) following severe TBI.Methods: High resolution (every 6 seconds) ICP data were collected in adults TBI from 2008–2010. Temperatures plotted against concurrent divided based on breakpoints...
Combat-related moderate-to-severe traumatic brain injury (CRTBI) is a significant cause of wartime morbidity and mortality. As August 2014, injuries sustained by members the Department Defense worldwide since 2000 totaled 32,996 cases. Previously published epidemiologic reviews describe CRTBI management at "strategic" level, but they lack "tactical" patient-specific data required for performance improvement. In addition, scarce exist regarding prehospital care.This prospective observational...
Determining the most effective treatments for complex medical conditions requires robust clinical data. Clinical registries comprise real-world observational data, which allow rapid assessment of effectiveness and care processes. In 2014 AUA (American Urological Association) launched AQUA (AUA Quality) Registry, a national urological disease registry intended to measure report health quality patient outcomes, support services comparative research. The initial focus is newly diagnosed...
