Predictors and outcomes of delirium in the emergency department during the first wave of the COVID-19 pandemic in Milan.

Background: Respiratory infections can be complicated by acute brain failure. We assessed delirium prevalence, predictors and outcomes in COVID-19 ED patients.

Methods: This was a retrospective observational study conducted at the San Raffaele ED (Italy).

Role of cardiological specialistic evaluation in patients with chest pain presenting in the emergency department.

Aims: Aim of this study was to evaluate the impact of cardiological and echocardiographic evaluation in addition to a standard clinical and instrumental approach on diagnostic and prognostic accuracy in patients presenting in the emergency department (ED) with chest pain (CP). Acute coronary syndromes, pulmonary embolism and acute aortic syndromes (AAS) (triple-rule-out/TRO) were considered.

Methods: From 7040 patients presenting with CP from 1 January 2015 to 31 December 2017, we randomly selected a sample of 1119.

Quantitative assessment of lung involvement on chest CT at admission: Impact on hypoxia and outcome in COVID-19 patients.

Background: The aim of this study was to quantify COVID-19 pneumonia features using CT performed at time of admission to emergency department in order to predict patients' hypoxia during the hospitalization and outcome.

Methods: Consecutive chest CT performed in the emergency department between March 1st and April 7th 2020 for COVID-19 pneumonia were analyzed. The three features of pneumonia (GGO, semi-consolidation and consolidation) and the percentage of well-aerated lung were quantified using a HU threshold based software.

Pulmonary Vascular Thrombosis in COVID-19 Pneumonia.

Objectives: During severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, dramatic endothelial cell damage with pulmonary microvascular thrombosis have been was hypothesized to occur. The aim was to assess whether pulmonary vascular thrombosis (PVT) is due to recurrent thromboembolism from peripheral deep vein thrombosis or to local inflammatory endothelial damage, with a superimposed thrombotic late complication.

Design: Observational study.

Chest CT in the emergency department for suspected COVID-19 pneumonia.

Purpose: In overwhelmed emergency departments (EDs) facing COVID-19 outbreak, a swift diagnosis is imperative. CT role was widely debated for its limited specificity. Here we report the diagnostic role of CT in two EDs in Lombardy, epicenter of Italian outbreak.
