Current vaccines for the Coronavirus Disease of 2019 (COVID-19) have demonstrated efficacy with low risk of adverse events. However, recent reports of thrombosis with thrombocytopenia syndrome (TTS) associated with adenovirus vector vaccines have raised concern. ⋯ With increasing vaccine distribution, it is essential for emergency clinicians to be aware of the evaluation and management of this condition.

Multicenter Study
Predictors of intubation in COVID-19 patients undergoing awake proning in the emergency department.
Awake prone positioning (PP) has been used to avoid intubations in hypoxic COVID-19 patients, but there is limited evidence regarding its efficacy. Moreover, clinicians have little information to identify patients at high risk of intubation despite awake PP. We sought to assess the intubation rate among patients treated with awake PP in our Emergency Department (ED) and identify predictors of need for intubation. ⋯ Among COVID-19 patients treated with awake PP in the ED prior to admission, ROX index and P/F ratio, particularly 24 h after admission, may be useful tools in identifying patients at high risk of intubation.

Multicenter Study
Development and validation of a nomogram to predict in-hospital cardiac arrest among patients admitted with acute coronary syndrome.
This study aimed to develop and validate a nomogram to recognize in-hospital cardiac arrest (CA) in patients with acute coronary syndrome (ACS). ⋯ Our study generated a friendly risk score to recognize in-hospital CA with good discrimination and calibration. Further studies need to establish a pathway to guide the application of the risk score in clinical practice.

This is a review of the underlying causes of the association of ST segment elevation and gastrointestinal symptoms such as abdominal pain, nausea, vomiting, and anorexia, in patients who do not have chest pain. The review was based on anecdotal reports in Googlescholar and Pubmed using the search terms, abdominal pain, nausea, vomiting, anorexia, ST elevation, myocardial infarction, and Takotsubo cardiomyopathy. Those patients who did not have acute myocardial infarction as the cause of the association of ST segment elevation and gastrointestinal symptoms were compared with counterparts with similar symptoms who had well authenticated acute myocardial infarction or Takotsubo cardiomyopathy as the underlying cause of ST segment elevation. ⋯ However, each of those disorders could also coexist either with acute myocardial infarction or with Takotsubo cardiomyopathy. The coexistence of ST segment elevation and gastrointestinal symptoms(without chest pain) was also documented in patients with esophageal perforation, mesenteric ischaemia, aortic dissection, Kounis syndrome, and in electrolyte disorders. In the context of presentation with gastroenterological symptoms but without concurrent chest pain, echocardiography appeared to be useful in distinguishing between "pseudo" myocardial infarction characterised by ST segment elevation in the absence of cardiac disease vs ST segment elevation attributable either to acute myocardial infarction or to Takotsubo cardiomyopathy.

Several studies have previously reported that a prolonged emergency department length of stay (EDLOS) is associated with poor outcomes in critically ill patients. This study was performed to investigate the relationship between the EDLOS and the neurologic outcome at 28 days in out-of-hospital cardiac arrest (OHCA) patients. ⋯ An EDLOS longer than 275 min after the ROSC was independently associated with a poor neurologic outcome at 28 days.
