Supplemental oxygen for pulmonary embolism (SO-PE): study protocol for a mechanistic, randomised, blinded, cross-over study.

Background: Acute pulmonary embolism (PE) mortality is linked to abrupt rises in pulmonary artery (PA) pressure due to mechanical obstruction and pulmonary vasoconstriction, leading to right ventricular (RV) dilation, increased RV wall tension and oxygen demand, but compromised right coronary artery oxygen supply. Oxygen is a known pulmonary vasodilator, and in preclinical animal models of PE, supplemental oxygen reduces PA pressures and improves RV function. However, the mechanisms driving these interactions, especially in humans, remain poorly understood.

A quantitative needs assessment for a tele-ultrasound consult program in a tertiary care Emergency Department.

Point-of-care ultrasound (POCUS) has been shown to be beneficial in facilitating patient care, but its adoption is variable among emergency medicine (EM) clinicians. We identified the patterns of POCUS use and gaps in POCUS integration in a tertiary care emergency department (ED). These data provide a user-centered platform for subsequent development of a tele-ultrasound (tele-US) consultation program.

Next-generation methods for early disease detection in crops.

Plant pathogens are commonly identified in the field by the typical disease symptoms that they can cause. The efficient early detection and identification of pathogens are essential procedures to adopt effective management practices that reduce or prevent their spread in order to mitigate the negative impacts of the disease. In this review, the traditional and innovative methods for early detection of the plant pathogens highlighting their major advantages and limitations are presented and discussed.

Association of Sonographic Sarcopenia and Falls in Older Adults Presenting to the Emergency Department.

Background And Objective: To determine the association between point-of-care-ultrasonography (POCUS)-measured sarcopenia and grip strength, as well as the history of prior-year falls among older adults admitted to the emergency department observation unit (EDOU).

Materials And Methods: This cross-sectional observational study was conducted over 8 months at a large urban teaching hospital. A consecutive sample of patients who were 65 years or older and admitted to the EDOU were enrolled in the study.

Advanced practice providers proficiency-based model of ultrasound training and practice in the ED.

Competency in the application of point-of-care ultrasound (POCUS) has come to be an expected fundamental skill set for advanced practice providers (APPs) in the emergency department. Both American College of Emergency Physicians and the Society of Emergency Medicine Physician Assistants approve of and endorse POCUS use by APPs. However, clinical exposure to and practice of ultrasound in this setting is often variable and without structure.
