Tranexamic Acid and Pulmonary Complications: A Secondary Analysis of an EAST Multicenter Trial.

Background: Anti-inflammatory effects of tranexamic acid (TXA) in reducing trauma endotheliopathy may protect from acute lung injury. Clinical data showing this benefit in trauma patients is lacking. We hypothesized that TXA administration mitigates pulmonary complications in penetrating trauma patients.

A Novel REBOA Training Curriculum for Emergency Medicine Residents: A Pilot Study.

Background: Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) is a potentially life-saving intervention to treat noncompressible torso hemorrhage. Traditionally, REBOA use has been limited to surgeons. However, emergency physicians are often the first point-of-contact and are well-versed in obtaining rapid vascular access and damage control resuscitation, making them ideal candidates for REBOA training.

pREBOA versus ER-REBOA impact on blood utilization and resuscitation requirements: A pilot analysis.

Background: Partial occlusion of the aorta is a resuscitation technique designed to maximize proximal perfusion while allowing a graduated amount of distal flow to reduce the ischemic sequelae associated with complete aortic occlusion. The pREBOA-PRO catheter affords the ability to titrate perfusion as hemodynamics allows; however, the impact of this new technology for resuscitative endovascular balloon occlusion of the aorta (REBOA) on blood use and other resuscitative requirements is currently unknown. We hypothesize that patients undergoing REBOA with the pREBOA-PRO catheter will utilize partial occlusion, when appropriate, and decrease overall resuscitative requirements when compared to patients undergoing REBOA with the ER-REBOA catheter.

Qualitative Analysis of the Lived Experience of Reproductive and Pediatric Health Care in the Military Health Care System.

Introduction: Persistent inequities exist in obstetric and neonatal outcomes in military families despite universal health care coverage. Though the exact underlying cause has not been identified, social determinants of health may uniquely impact military families. The purpose of this study was to qualitatively investigate the potential impact of social determinants of health and the lived experiences of military individuals seeking maternity care in the Military Health System.

Bone Anchor Fixation in the Repair of Blunt Traumatic Abdominal Wall Hernias: A Western Trauma Association Multicenter Study.

Background: Blunt traumatic abdominal wall hernias (TAWHs) are rare but require a variety of operative techniques to repair including bone anchor fixation (BAF) when tissue tears off bony structures. This study aimed to provide a descriptive analysis of BAF technique for blunt TAWH repair. Bone anchor fixation and no BAF repairs were compared, hypothesizing increased hernia recurrence with BAF repair.

Failure rates of nonoperative management of low-grade splenic injuries with active extravasation: an Eastern Association for the Surgery of Trauma multicenter study.

Objectives: There is little evidence guiding the management of grade I-II traumatic splenic injuries with contrast blush (CB). We aimed to analyze the failure rate of nonoperative management (NOM) of grade I-II splenic injuries with CB in hemodynamically stable patients.

Methods: A multicenter, retrospective cohort study examining all grade I-II splenic injuries with CB was performed at 21 institutions from January 1, 2014, to October 31, 2019.

Balloon Rises Above: REBOA at Zone 1 May Be Superior to Resuscitative Thoracotomy.

Background: The use of Zone 1 REBOA for life-threatening trauma has increased dramatically.

Study Design: The Aortic Occlusion for Resuscitation in Trauma and Acute Care Surgery database was queried for blunt and penetrating trauma between 2013 and 2021. Outcomes were examined both for mechanisms of injury combined and separately and for combinations of abdominal injury with and without traumatic brain injury and chest injuries (Abbreviated Injury Scale [AIS] score >2).

Interprofessional obstetric simulation training improves postpartum haemorrhage management and decreases maternal morbidity: a before-and-after study.

Design: Before-and-after study.

Setting: Maternity care hospitals within the USA.

Titratable partial aortic occlusion: Extending Zone I endovascular occlusion times.

Background: Extending the time to definitive hemorrhage control in noncompressible torso hemorrhage (NCTH) is of particular importance in the battlefield where transfer times are prolonged and NCTH remains the leading cause of death. While resuscitative endovascular balloon occlusion of the aorta is widely practiced as an initial adjunct for the management of NCTH, concerns for ischemic complications after 30 minutes of compete aortic occlusion deters many from zone 1 deployment. We hypothesize that extended zone 1 occlusion times will be enabled by novel purpose-built devices that allow for titratable partial aortic occlusion.

Systematic review to evaluate algorithms for REBOA use in trauma and identify a consensus for patient selection.

Background: Patient selection for resuscitative endovascular balloon occlusion of the aorta (REBOA) has evolved during the last decade. A recent multicenter collaboration to implement the newest generation REBOA balloon catheter identified variability in patient selection criteria. The aims of this systematic review were to compare recent REBOA patient selection guidelines and to identify current areas of consensus and variability.

Comparison of Levels of Nasal, Salivary, and Plasma Antibody to Severe Acute Respiratory Syndrome Coronavirus 2 During Natural Infection and After Vaccination.

Background: Most studies of immunity to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) measure antibody or cellular responses in blood; however, the virus infects mucosal surfaces in the nose and conjunctivae and infectious virus is rarely if ever present in the blood.

Methods: We used luciferase immunoprecipitation assays to measure SARS-CoV-2 antibody levels in the plasma, nose, and saliva of infected persons and vaccine recipients. These assays measure antibody that can precipitate the SAR-CoV-2 spike and nucleocapsid proteins.

Which Patients Receive Diagnostic Angiography? An EAST Multicenter Study Analysis of Internal Carotid Artery Blunt Cerebrovascular Injury.

Background: Digital subtraction angiography (DSA) is the gold standard radiologic modality in blunt cerebrovascular injury (BCVI). However, computerized tomography angiography (CTA) is primarily used in modern practice with CTA's widespread availability and the decreased stroke rate with CTA use. The frequency and indications for DSA in BCVI is undefined.

The development, implementation, and evaluation of a medical student peer teaching training curriculum during a high-fidelity prehospital trauma simulation.

Objectives: While peer teaching has been found to be an effective technique during simulation, no peer teaching training curriculum (PTTC) has been developed for simulation-based learning. The objective of this study, therefore, was to develop, implement, and evaluate a PTTC during a high-fidelity trauma simulation.

Methods: When developing the PTTC, we combined several validated learning models for teaching and learning procedural skills.

A Grounded Theory Approach to Navigating Infertility Care During U.S. Military Service.

Methods: A post-hoc analysis of a prospective, observational study at 16 U.

Resuscitative endovascular balloon occlusion of the aorta (REBOA) may be superior to resuscitative thoracotomy (RT) in patients with traumatic brain injury (TBI).

Background: The effects of aortic occlusion (AO) on brain injury are not well defined. We examined the impact of AO by resuscitative endovascular balloon occlusion of the aorta (REBOA) and resuscitative thoracotomy (RT) on outcomes in the setting of traumatic brain injury (TBI).

Methods: Patients sustaining TBI who underwent RT or REBOA in zone 1 (thoracic aorta) from September 2013 to December 2018 were identified.

Survival benefit for pelvic trauma patients undergoing Resuscitative Endovascular Balloon Occlusion of the Aorta: Results of the AAST Aortic Occlusion for Resuscitation in Trauma Acute Care Surgery (AORTA) Registry.

Background: Aortic occlusion (AO) to facilitate the acute resuscitation of trauma and acute care surgery patients in shock remains a controversial topic. Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) is an increasingly deployed method of AO. We hypothesized that in patients with non-compressible hemorrhage below the aortic bifurcation, the use of REBOA instead of open AO may be associated with a survival benefit.

Sharp decline in rates of community respiratory viral detection among patients at the National Institutes of Health Clinical Center during the coronavirus disease 2019 (COVID-19) pandemic.

Objectives: To analyze the frequency and rates of community respiratory virus infections detected in patients at the National Institutes of Health Clinical Center (NIHCC) between January 2015 and March 2021, comparing the trends before and during the coronavirus disease 2019 (COVID-19) pandemic.

Methods: We conducted a retrospective study comparing frequency and rates of community respiratory viruses detected in NIHCC patients between January 2015 and March 2021. Test results from nasopharyngeal swabs and washes, bronchoalveolar lavages, and bronchial washes were included in this study.

Obstetric Simulation Training and Teamwork: Immediate Impact on Knowledge, Teamwork, and Adherence to Hemorrhage Protocols.

Introduction: The Obstetric Simulation Training and Teamwork (OB-STaT) curriculum was an in situ interprofessional program to provide standardized postpartum hemorrhage (PPH) simulation training throughout a health system to decrease PPH morbidity. In this study portion, investigators hypothesized that OB-STaT would increase: (a) team member knowledge in diagnosis and management of PPH, (b) teamwork, (c) adherence to established PPH protocols, and (d) patient satisfaction.

Methods: The OB-STaT was implemented at 8 US Navy hospitals between February 2018 and November 2019.

Budget impact analysis of niraparib for first-line maintenance therapy in advanced ovarian cancer from a US payer perspective.

Ovarian cancer (OC) is the fifth leading cause of cancer death in women and has the highest mortality rate of gynecological cancers. Niraparib was recently approved by the FDA for the maintenance treatment of adult patients with advanced epithelial OC in complete or partial response to first-line platinum-based chemotherapy (PBC) regardless of biomarker status. To estimate the direct economic impact on US payers of adding niraparib as a first-line maintenance therapy for patients with advanced OC.

Towards quantifying the mass extinction debt of the Anthropocene.

To make sense of our present biodiversity crises, the modern rate of species extinctions is commonly compared to a benchmark, or 'background,' rate derived from the fossil record. These estimates are critical for bounding the scale of modern diversity loss, but are yet to fully account for the fundamental structure of extinction rates through time. Namely, a substantial fraction of extinctions within the fossil record occurs within relatively short-lived extinction pulses, and not during intervals characterized by background rates of extinction.

A multicenter trial of current trends in the diagnosis and management of high-grade pancreatic injuries.

Background: Outcomes following pancreatic trauma have not improved significantly over the past two decades. A 2013 Western Trauma Association algorithm highlighted emerging data that might improve the diagnosis and management of high-grade pancreatic injuries (HGPIs; grades III-V). We hypothesized that the use of magnetic resonance cholangiopancreatography, pancreatic duct stenting, operative drainage versus resection, and nonoperative management of HGPIs increased over time.

Pooled Saliva Specimens for SARS-CoV-2 Testing.

We evaluated saliva (SAL) specimens for SARS-CoV-2 reverse transcriptase PCR (RT-PCR) testing by comparison of 459 prospectively paired nasopharyngeal (NP) or midturbinate (MT) swabs from 449 individuals with the aim of using saliva for asymptomatic screening. Samples were collected in a drive-through car line for symptomatic individuals ( = 380) and in the emergency department (ED) ( = 69). The percentages of positive and negative agreement of saliva compared to nasopharyngeal swab were 81.
