Mortality in patients treated for COVID-19 in the emergency department of a tertiary care hospital during the first phase of the pandemic: Derivation of a risk model for emergency departments.

Objectives: To develop a risk model to predict 30-day mortality after emergency department treatment for COVID-19.

Material And Methods: Observational retrospective cohort study including 2511 patients with COVID-19 who came to our emergency department between March 1 and April 30, 2020. We analyzed variables with Kaplan Meier survival and Cox regression analyses.

Factors associated with revisits by patients with SARS-CoV-2 infection discharged from a hospital emergency department.

Objectives: To analyze emergency department (ED) revisits from patients discharged with possible coronavirus disease 2019 (COVID-19).

Material And Methods: Retrospective observational study of consecutive patients who came to the ED over a period of 2 months and were diagnosed with possible COVID-19. We analyzed clinical and epidemiologic variables, treatments given in the ED, discharge destination, need to revisit, and reasons for revisits.

Cardiac tamponade and severe pericardial effusion in systemic sclerosis: report of nine patients and review of the literature.

Aim: To describe the clinical characteristics, treatment and outcome of patients with systemic sclerosis (SSc) developing severe pericardial effusion or cardiac tamponade.

Methods: SSc patients with severe pericardial effusion or cardiac tamponade from three Spanish hospitals were collected. In addition, a computer-assisted (PubMed, MEDLINE) search of the literature to identify all cases of cardiac tamponade or severe pericardial effusion associated with SSc reported in English, French and Spanish from 1987 through September 2015 was performed.
