Meta Analysis
Significant association between anemia and higher risk for COVID-19 mortality: A meta-analysis of adjusted effect estimates.
This study aimed to evaluate whether there was a significant relationship between anemia and the risk for mortality among coronavirus disease 2019 (COVID-19) patients by a quantitative meta-analysis based on the adjusted effect estimates. ⋯ Our meta-analysis based on risk factors-adjusted effect estimates indicated that anemia was independently associated with a significantly elevated risk for mortality among COVID-19 patients.

Randomized Controlled Trial
Comparison of saline versus air for identifying endotracheal intubation with ultrasound.
After intubation has been performed, it is important to rapidly confirm the correct location of the endotracheal tube (ETT). Multiple techniques have been described, each with different limitations. Ultrasound has been increasingly recognized as an alternate modality for identifying the ETT location. However, it can be challenging to visualize the air-filled ETT cuff. Saline insufflation of the ETT cuff has been suggested to improve visualization of the ETT but data are limited. Our study sought to compare the diagnostic accuracy of air versus saline ETT cuff inflation on the diagnostic accuracy of intubation. ⋯ There was no statistically significant difference between air versus saline for intubation confirmation. However, saline was associated with fewer false negatives. Additionally, time to confirmation was faster and operator confidence was higher with the saline group. Further studies should determine if the outcomes would change with more novice sonographers or in specific patient populations.

Randomized Controlled Trial
Oral Aspirin/ketamine versus oral ketamine for emergency department patients with acute musculoskeletal pain.
The purpose of this study is to investigate if an orally administered combination of aspirin and ketamine will provide better analgesia than a ketamine alone in adult patients presenting to the Emergency Department (ED) with acute musculoskeletal pain. ⋯ govRegistration: NCT04860804.

Multicenter Study
Frontal QRS/T angle can predict mortality in COVID-19 patients.
The frontal QRS-T (fQRS) angle has been investigated in the general population, including healthy people and patients with heart failure. The fQRS angle can predict mortality due to myocarditis, ischaemic and non-ischaemic cardiomyopathies, idiopathic dilated cardiomyopathy, and chronic heart failure in the general population. Moreover, no studies to date have investigated fQRS angle in coronavirus disease 2019 (COVID-19) patients. Thus, the purpose of this retrospective multicentre study was to evaluate the fQRS angle of COVID-19 patients to predict in-hospital mortality and the need for mechanical ventilation. ⋯ In conclusion, a wide fQRS angle >90° was a predictor of in-hospital mortality and associated with the need for mechanical ventilation among COVID-19 patients.
