Design: Retrospective propensity-matched study.

Propensity matched analysis examining the effect of passive reversal of direct oral anticoagulants on blood loss and the need for transfusions among traumatic geriatric hip fractures.

Background: Reversal of direct oral anticoagulants (DOACs) is currently recommended prior to emergent surgery, such as surgical intervention for traumatic geriatric hip fractures. However, reversal methods are expensive and timely, often delaying surgical intervention, which is a predictor of outcomes. The study objective was to examine the effect of DOAC reversal on blood loss and transfusions among geriatric patients with hip fractures.

Oxidation‑reduction potential parameters worsen following intraarterial therapy in patients with reduced collateral circulation and middle cerebral artery occlusions.

Collateral circulation is important for cerebral perfusion in acute ischemic strokes. Monitoring the oxidation-reduction potential (ORP) may be useful to assess collateral status or treatment efficacy. The objectives of the present study were to determine if the ORP was associated with collateral circulation status in middle cerebral artery (MCA) occlusions and to identify patterns in the ORP and the collateral circulation status among patients treated with intraarterial therapy (IAT) over time.

Methods: This retrospective cohort study compared stroke patients admitted to a comprehensive stroke center during the COVID-19 pandemic April 1 2020 to June 30 2020 (COVID-19) to patients admitted April 1 2019 to June 30 2019. We examined stroke admission volume and acute stroke treatment use.

Partial warfarin reversal prior to hip fracture surgical intervention in geriatric trauma patients effects on blood loss and transfusions.

Background: Warfarin reversal is typically sought prior to surgery for geriatric hip fractures; however, patients often proceed to surgery with partial warfarin reversal. The effect of partial reversal (defined as having an international normalized ratio [INR] > 1.5) remains unclear.

Examining emergency medical services' prehospital transport times for trauma patients during COVID-19.

Introduction: Longer prehospital times were associated with increased odds for survival in trauma patients. The purpose of this study was to determine how the COVID-19 pandemic affected emergency medical services (EMS) prehospital times for trauma patients.

Methods: This retrospective cohort study compared trauma patients transported via EMS to six US level I trauma centers admitted 1/1/19-12/31/19 (2019) and 3/16/20-6/30/20 (COVID-19).

Processes for Trauma Care at Six Level I Trauma Centers During the COVID-19 Pandemic.

Introduction: As the COVID-19 pandemic spread, patient care guidelines were published and elective surgeries postponed. However, trauma admissions are not scheduled and cannot be postponed. There is a paucity of information available on continuing trauma care during the pandemic.

Supplementing chestnut tannins in the broiler diet mediates a metabolic phenotype of the ceca.

As the demand for alternatives to antibiotic growth promoters (AGP) increases in food animal production, phytobiotic compounds gain popularity because of their ability to mimic the desirable bioactive properties of AGP. Chestnut tannins (ChT) are one of many phytobiotic compounds used as feed additives, particularly in South America, for broilers because of its favorable antimicrobial and growth promotion capabilities. Although studies have observed the microbiological and immunologic effects of ChT, there is a lack of studies evaluating the metabolic function of ChT.

Utilization of pre-hospital pelvic circumferential compression devices for pelvic fractures: survey of U.S. level I trauma centers.

Introduction: There is a lack of data on the use and effectiveness of pre-hospital pelvic circumferential compression devices (PCCD) as a temporary intervention for pelvic fracture management; they are thought to decrease pelvic volume and hemorrhage but are not without risks. The purpose of this study is to examine pre-hospital PCCD practices at US Level I trauma centers.

Methods: This was a prospective cross-sectional survey of trauma medical directors at US Level I trauma centers.

A three-year retrospective multi-center study on time to surgery and mortality for isolated geriatric hip fractures.

Background: There are multiple reports on the effect of time to surgery for geriatric hip fractures; it remains unclear if earlier intervention is associated with improved mortality, hospital length of stay (HLOS), or cost.

Methods: This was a multi-center retrospective cohort study. Patients (≥65y.

Our objective was to describe aSAH patients' outcomes after transitioning from a neurosurgery-led intensive care unit (ICU) to a neurology-led multidisciplinary care neurocritical care unit (NCCU). The study hypothesis was that the neurology-led multidisciplinary care would improve patient outcomes.

Variability in the timeliness of interventional radiology availability for angioembolization of hemodynamically unstable pelvic fractures: a prospective survey among U.S. level I trauma centers.

Background: Patients with hemodynamically unstable pelvic fractures have high mortality due to delayed hemorrhage control. We hypothesized that the availability of interventional radiology (IR) for angioembolization may vary in spite of the mandated coverage at US Level I trauma centers, and that the priority treatment sequence would depend on IR availability.

Methods: This survey was designed to investigate IR availability and pelvic fracture management practices.

Variability in pelvic packing practices for hemodynamically unstable pelvic fractures at US level 1 trauma centers.

Background: Mortality from hemodynamically unstable pelvic fractures remains high. Guidelines offer varying care approaches including the use of pelvic packing (PP), which was recently adopted for potential control of bleeding for this condition. However, the implementation of PP is uncertain as the debate on the optimal resuscitation strategy, angioembolization or PP continues.
