Background Delayed encephalopathy (DE) is the most severe complication after acute carbon monoxide (CO) poisoning, which seriously affects the outcome of patients and leads to a high disability rate. Prior studies have shown that hyperbaric oxygen (HBO2) therapy is therapeutic for DE due to reducing immune-mediated neuropathology and thus improving cognitive performance. Methods In our present perspective study, five DE patients were treated regularly with HBO2 therapy. ⋯ Conclusion The application of HBO2 therapy is of significance in improving the cognition of DE patients, along with mobilized circulating stem cells. We primarily infer that the CD34+/CD90+ and CD34+/CD133+ cells were mobilized by HBO2 exposure and have played a positive role in cognition improvement on DE patients by up-regulation of BDNF, nestin and SYP. The altering amount of circulating stem cells mobilized in peripheral blood could be a potential marker on predicting the outcome of DE.

Electrical cardioversion of ED patients is a well-described treatment strategy for certain patients presenting with atrial fibrillation (AF). The objective of this study was to describe the safety and outcomes of this practice in a cohort of patients undergoing ED electrical cardioversion for AF. ⋯ In this cohort of ED patients with atrial fibrillation, ED electrical cardioversion followed by discharge to home was largely safe and effective. Most complications were transient and mild. There were remarkably few serious complications.

Observational Study
Impact of COVID-19 pandemic on visits of an urban emergency department.
The aim of this study was to reveal how the pandemic process affected the number of ED visits and the reasons for application. ⋯ Number of ED visits during the pandemic were decreased by half when compared to the previous year. It was an advantage of the pandemic to decrease ED visits due to "nonemergent" complaints, and thus, unnecessary patient burden. However, on the other hand, patients avoided seeking medical attention, even for life-threatening conditions which led to increased mortality and morbidity.

A mycotic aneurysm is a life-threatening disease that usually presents with nonspecific symptoms. A prompt diagnosis is essential because of the risk of aneurysm rupture and high mortality rate. We describe a case of an abdominal mycotic aortic aneurysm presenting as chronic constipation for 3 weeks, without fever or abdominal pain. Point-of-care ultrasound has the ability to detect silent abdominal aortic aneurysms and serves as a follow-up tool for patients under medical treatment.
