The objective of this review was to assess the diagnostic accuracy of bedside-focused transthoracic echocardiography (TTE) in acute atraumatic thoracic aortic syndrome in adults. We performed a systematic review and meta-analysis of publications that described the use of bedside-focused TTE on adults presenting to emergency care settings with suspected atraumatic thoracic aortic syndrome. Studies were identified using keyword and MeSH on relevant databases as well as grey literature, followed by abstract screening and study selection by two independent reviewers.

To explore and address this problem, a quality improvement project was undertaken in an emergency department. A consecutive sample of the most recent PoCUS examinations in a district general hospital emergency department in the United Kingdom was audited.

Method: Online databases, specialist websites and social media platforms were searched to identify studies that explore the utility of LUS in COVID-19.
The effects of metal ion exposure on osteocytes, the most abundant cell type in bone and responsible for coordinating bone remodeling, remain unclear. However, several studies have previously shown that exposure to cobalt (Co ) and chromium (Cr ), at concentrations equivalent to those found clinically, affect osteoblast and osteoclast survival and function. In this study, we tested the hypothesis that metal ions would similarly impair the normal physiology of osteocytes.
