Transitioning From Anesthesia to Emergency Medicine for Airway Management in Rural Trauma Patients.

Introduction: When our rural trauma center first became certified in 1986, the Emergency Department (ED) was a mix of board-certified Emergency Medicine (EM) and Family Medicine trained physicians each with various degrees of airway experience. Therefore, Anesthesia providers had provided airway management during trauma activations for decades. Recently, our institution saw dramatic growth in the ED which is now staffed by board certified EM physicians and complemented by an EM residency program.

Retrospective Validation of Brain Injury Guidelines in a Rural Level II Trauma Center.

Introduction: The routine transfer of mild to moderate traumatic brain injuries (TBIs) to trauma centers with neurosurgical capabilities has recently been re-evaluated. The Brain Injury Guidelines (BIG) were developed to categorize TBI patients into three categories (BIG-1, BIG-2, and BIG-3), each representing a progressively increasing risk of clinical deterioration. This classification system has been previously validated at both level I and level III trauma centers.

Stability, electronic properties and CO adsorption properties of bimetallic PtAg/Pt(111) surfaces.

Aiming at a better fundamental understanding of the chemistry of bimetallic PtAg/Pt(111) surfaces, we have investigated the stability, electronic properties and CO adsorption properties of bimetallic PtAg surfaces, including pseudomorphic Ag film covered Pt(111) surfaces and PtAg/Pt(111) monolayer surface alloys, using periodic density functional theory calculations. The data provide detailed insights into the relative stabilities of different surface configurations, as indicated by their formation enthalpies and surface energies, and changes in their electronic properties, , in the projected local densities of states and shifts in the d-band center. The adsorption properties of different Pt ensembles were systematically tested using CO as a probe molecule.

Trends of Trauma Admissions in a Rural Trauma Center During Coronavirus Disease 2019 Pandemic.

Introduction: The spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) led to implementing strict social distancing mandates nationwide. This study evaluates the trauma trends during the pandemic at a rural level II trauma center in Pennsylvania.

Methods: A retrospective review of all trauma registries between 2018 and 2021 was performed overall and on a 6-month basis.

Unveiling the CO Oxidation Mechanism over a Molecularly Defined Copper Single-Atom Catalyst Supported on a Metal-Organic Framework.

Elucidating the reaction mechanism in heterogeneous catalysis is critically important for catalyst development, yet remains challenging because of the often unclear nature of the active sites. Using a molecularly defined copper single-atom catalyst supported by a UiO-66 metal-organic framework (Cu/UiO-66) allows a detailed mechanistic elucidation of the CO oxidation reaction. Based on a combination of in situ/operando spectroscopies, kinetic measurements including kinetic isotope effects, and density-functional-theory-based calculations, we identified the active site, reaction intermediates, and transition states of the dominant reaction cycle as well as the changes in oxidation/spin state during reaction.
