Comparative Study Observational Study
Integrating point-of-care ultrasound in the ED evaluation of patients presenting with chest pain and shortness of breath.
The differential diagnoses of patients presenting with chest pain (CP) and shortness of breath (SOB) are broad and non-specific. We aimed to 1) determine how use of point-of-care ultrasound (POCUS) impacted emergency physicians' differential diagnosis, and 2) evaluate the accuracy of POCUS when compared to chest radiograph (CXR) and composite final diagnosis. ⋯ In evaluation of patients with CP and SOB, POCUS is a highly feasible diagnostic test which can assist in narrowing down the differential diagnoses. In patients with a normal thoracic ultrasound, the added value of a CXR may be minimal.

Retracted Publication
Vascular permeability and hemodynamic effects of ulinastatin on organs affected by shock during early burn injury.
This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/our-business/policies/article-withdrawal). This article has been retracted at the request of the authors due to errors in the data. The authors indicated that they expanded the original sample size from 12 to 50, to study blood circulation upon other types of burns. ⋯ The decrease in blood volume of the experimental group was not significantly slowed compared to the control group as reported. Since that was the basis of this work, this flaw may shatter all resulting hemodynamic data measured by the PICCO method. The authors have been unable to determine the source of the error.
