TL;DR: In an emergency setting, this new ultraportable echoscope (PUD) was reliable for the real-time detection of focused cardiac abnormalities.

Abstract: Introduction In the emergency setting, focused cardiac ultrasound has become a fundamental tool for diagnostic, initial emergency treatment and triage decisions. A new ultra-miniaturized pocket ultrasound device (PUD) may be suited to this specific setting. Therefore, we aimed to compare the diagnostic ability of an ultra-miniaturized ultrasound device (Vscan™, GE Healthcare, Wauwatosa, WI) and of a conventional high-quality echocardiography system (Vivid S5™, GE Healthcare) for a cardiac focused ultrasonography in patients admitted to the emergency department.

Abstract: Richtig eingesetzt, hilft die moderne Ultraschalldiagnostik dem Nephrologen gerade in Notfallsituationen auf der Station, in der Dialyse und in der Notaufnahme dabei, rasch die richtige Diagnose zu stellen bzw. als diagnostischer Weichensteller zeitsparend die korrekten nachsten diagnostischen und therapeutischen Schritte einzuleiten. Neben der konventionellen B‑Bild‑/Grauwertsonographie und der Dopplersonographie haben neue Ultraschallkopfe mit hoherer Ortsauflosung (Hochfrequenzsonographie) und v. a. die Kontrastmittelsonographie die technischen Moglichkeiten deutlich erweitert und helfen Nephrologen und Internisten, insbesondere an den Nieren diagnostisch-klinische Fragestellungen zu beantworten, die bislang nur mittels kontrastverstarkter Computertomographie oder Magnetresonanztomographie geklart werden konnten. Dies erlaubt dem Nierenarzt im Jahr 2021, die Klinik, die Bildgebung und sein pathophysiologisches Wissen in idealer Weise zeitsparend zum Nutzen des Patienten zusammenfuhren zu konnen.

Abstract: This paper presents a general statistical methodology for the analysis of multivariate categorical data arising from observer reliability studies. The procedure essentially involves the construction of functions of the observed proportions which are directed at the extent to which the observers agree among themselves and the construction of test statistics for hypotheses involving these functions. Tests for interobserver bias are presented in terms of first-order marginal homogeneity and measures of interobserver agreement are developed as generalized kappa-type statistics. These procedures are illustrated with a clinical diagnosis example from the epidemiological literature.

Abstract: CONSIDER Table 1. It represents in its formal characteristics a situation which arises in the clinical-social-personality areas of psychology, where it frequently occurs that the only useful level of measurement obtainable is nominal scaling (Stevens, 1951, pp. 2526), i.e. placement in a set of k unordered categories. Because the categorizing of the units is a consequence of some complex judgment process performed by a &dquo;two-legged meter&dquo; (Stevens, 1958), it becomes important to determine the extent to which these judgments are reproducible, i.e., reliable. The procedure which suggests itself is that of having two (or more) judges independently categorize a sample of units and determine the degree, significance, and

Abstract: Quantification of cardiac chamber size, ventricular mass and function ranks among the most clinically important and most frequently requested tasks of echocardiography. Over the last decades, echocardiographic methods and techniques have improved and expanded dramatically, due to the introduction of higher frequency transducers, harmonic imaging, fully digital machines, left-sided contrast agents, and other technological advancements. Furthermore, echocardiography due to its portability and versatility is now used in emergency rooms, operating rooms, and intensive care units. Standardization of measurements in echocardiography has been inconsistent and less successful, compared to other imaging techniques and consequently, echocardiographic measurements are sometimes perceived as less reliable. Therefore, the American Society of Echocardiography, working together with the European Association of Echocardiography, a branch of the European Society of Cardiology, has critically reviewed the literature and updated the recommendations for quantifying cardiac chambers using echocardiography. This document reviews the technical aspects on how to perform quantitative chamber measurements of morphology and function, which is a component of every complete echocardiographic examination.
