From "Airway scares me" to "I would say I'm pretty comfortable": quality improvement for reducing time to obtain equipment for adult advanced airway management in a rural emergency department.

Background: Management of the adult airway is one of the most stressful and time-critical procedures in emergency medicine. In the Cowichan District Hospital, a rural hospital in British Columbia, Emergency Department (ED) staff were uncomfortable with acquiring the equipment needed for adult advanced airway management and the mean length of time to acquire the equipment was 319 s. The aim of this quality improvement (QI) project was to decrease the time to obtain the equipment needed for adult advanced airway management by nurses and physicians in the Cowichan District Hospital ED to less than 90 s by May 2023.

Adding to the story, did penetrating trauma really increase? changes in trauma patterns during the COVID-19 pandemic: A multi-institutional, multi-region investigation.

Background: Results from single-region studies suggest that stay at home orders (SAHOs) had unforeseen consequences on the volume and patterns of traumatic injury during the initial months of the Coronavirus disease 2019 (COVID-19). The aim of this study was to describe, using a multi-regional approach, the effects of COVID-19 SAHOs on trauma volume and patterns of traumatic injury in the US.

Methods: A retrospective cohort study was performed at four verified Level I trauma centers spanning three geographical regions across the United States (US).

Grading of aortic valve stenosis at 64-slice spiral computed tomography: comparison with transthoracic echocardiography and calibration against cardiac catheterization.

Purpose: We sought to determine the accuracy of multislice spiral computed tomography (MSCT) for assessing of aortic valve stenosis and to establish threshold values of the planimetric aortic valve orifice area (AVA) that best separate between different grades of stenosis severity.

Materials And Methods: A total of 202 patients (among them 160 patients with aortic valve stenosis) underwent MSCT, transthoracic echocardiography (TTE) and cardiac catheterization (CATH). Planimetric AVA measurements at MSCT were compared with calculations based on Doppler flow velocity measurements by TTE (using the continuity equation) and pressure gradient measurements by CATH (using the Gorlin formula).

Bacteriophage SP6-specific RNA polymerase. II. Mapping of SP6 DNA and selective in vitro transcription.

DNA from bacteriophage SP6 grown on Salmonella typhimurium LT2 is a linear duplex with a unique DNA sequence having a molecular weight of 2.9 x 10(6) (43.500 base pairs).
