To assess the self-reported frequency of use of ultrasound guidance for central venous catheterization by emergency medicine (EM) residents, describe residents' perceptions regarding the use of ultrasound guidance, and identify barriers to the use of ultrasound guidance. ⋯ The use of self-reported ultrasound guidance for central venous catheterization significantly increased from 2007 to 2013 at academic institutions. Most residents were aware of the benefits of using ultrasound guidance. Although faculty adoption of ultrasound for central venous catheterization remains a barrier, it has decreased.

The activity of abdominal muscles mainly produces high expiratory pressure. These include the rectus abdominis, external oblique, internal oblique, and transverse abdominis muscles. The purpose of this study was to determine whether maximal expiratory pressure is associated with each abdominal muscle thickness at rest. ⋯ Our results indicate that the rectus abdominis muscle thickness might be more highly correlated with expiratory pressure production than the external oblique, internal oblique, and transverse abdominis muscle thickness.

Randomized Controlled Trial Comparative Study
Prediction of Left Ventricular Filling Pressure by 3-Dimensional Speckle-Tracking Echocardiography in Patients With Coronary Artery Disease.
The purpose of this study was to investigate the diagnostic value of 3-dimensional (3D) speckle-tracking echocardiography for estimating left ventricular filling pressure in patients with coronary artery disease (CAD) and a preserved left ventricular ejection fraction. ⋯ Three-dimensional speckle-tracking echocardiography was a practical technique for predicting elevated left ventricular filling pressure, but it might not be superior to the commonly used E/E' ratio in patients with CAD who have a normal left ventricular ejection fraction.

Ultrasound Integration in Undergraduate Medical Education: Comparison of Ultrasound Proficiency Between Trained and Untrained Medical Students.
The benefit of formal ultrasound implementation in undergraduate medical education remains unclear. The goal of this study was to evaluate the effectiveness of ultrasound curriculum implementation during year 1 medical student physical examination teaching on the ultrasound proficiency of medical students. ⋯ Implementation of an ultrasound curriculum in undergraduate medical education showed a significant increase in trained versus untrained medical student ultrasound capabilities.

Comparative Study
Evaluating Didactic Methods for Training Medical Students in the Use of Bedside Ultrasound for Clinical Practice at a Faculty of Medicine in Romania.
Medical students' time is limited, so efficiency in medical education is valued. This research project aimed to determine the most effective means to teach bedside ultrasound to medical students in a 1-week training course. We hypothesized that the best method would include a combination of podcasts and hands-on teaching; therefore, there would be a statistically significant difference among the various methods of teaching. ⋯ These results suggest that all 3 methods are equally effective in teaching novice medical students basic ultrasound knowledge and skills.
