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.

Potential value of urinary amatoxin quantification in patients with hepatotoxic mushroom poisoning.

Backgorund & Aims: Mushroom poisoning with Amanita phalloides or similar species can lead to liver failure with 10-30% mortality rates. We aimed at defining the prognostic value of urinary amatoxin quantification in patients with hepatotoxic mushroom poisoning.

Methods: Data from 32 patients with hepatotoxic mushroom poisoning (Hospital Clínic Barcelona, 2002-16) in whom urinary amatoxins were determined (ELISA) were retrospectively reviewed.

Time to diagnosis and associated costs of an outpatient vs inpatient setting in the diagnosis of lymphoma: a retrospective study of a large cohort of major lymphoma subtypes in Spain.

Background: Mainly because of the diversity of clinical presentations, diagnostic delays in lymphoma can be excessive. The time spent in primary care before referral to the specialist may be relatively short compared with the interval between hospital appointment and diagnosis. Although studies have examined the diagnostic intervals and referral patterns of patients with lymphoma, the time to diagnosis of outpatient compared to inpatient settings and the costs incurred are unknown.

Unintentional weight loss: Clinical characteristics and outcomes in a prospective cohort of 2677 patients.

Background: Whereas there are numerous studies on unintentional weight loss (UWL), these have been limited by small sample sizes, short or variable follow-up, and focus on older patients. Although some case series have revealed that malignancies escaping early detection and uncovered subsequently are exceptional, reported follow-ups have been too short or unspecified and necropsies seldom made. Our objective was to examine the etiologies, characteristics, and long-term outcome of UWL in a large cohort of outpatients.

Congenital heart block related to maternal autoantibodies: descriptive analysis of a series of 18 cases from a single center.

The objective of this study was to describe the clinical and immunological characteristics of maternal autoimmune-mediated fetal congenital heart block (CHB) in a cohort of pregnant women from an autoimmune disease pregnancy clinic. This is a retrospective observational study of all women presenting with CHB in our autoimmune disease pregnancy clinic from January 1997 to December 2014. In addition, perinatal outcome is also described.

Infection is the major trigger of hemophagocytic syndrome in adult patients treated with biological therapies.

Introduction: Hemophagocytic syndromes (hemophagocytic lymphohistiocytosis, HLH) are characterized by a wide range of etiologies, symptoms, and outcomes, but have a common etiopathogenic pathway leading to organ damage: an excessive inflammatory response. Biological therapies have been proposed as a therapeutic option for refractory HLH, but have also been related to the development of HLH in severe immunosuppressed patients.

Objectives And Methods: The purpose of this study was to analyze the clinical characteristics and outcomes of adult patients who developed HLH after receiving biological therapies.

Changes in the etiology, incidence and prognosis of acute lower respiratory track infections in human immunodeficiency virus patients.

Aim: To describe the incidence, the changes in the etiology and the prognosis of lower respiratory tract infection (LRTI) in HIV infected patients, presenting by the first time to the Emergency Department (ED), during years 2000-2010.

Study Design: Prospective collection of data.

Methods: Data were collected on the first visit of HIV-infected patients at our ED due to a LRTI, (defined according to the criteria of the European Respiratory Society), between 1/1/2000 and 31/12/2010.

Primary care referrals of patients with potentially serious diseases to the emergency department or a quick diagnosis unit: a cross-sectional retrospective study.

Background: In Spain, primary healthcare (PHC) referrals for diagnostic procedures are subject to long waiting-times, and physicians and patients often use the emergency department (ED) as a shortcut. We aimed to determine whether patients evaluated at a hospital outpatient quick diagnosis unit (QDU) who were referred to ED from 12 PHC centers could have been directly referred to QDU, thus avoiding ED visits. As a secondary objective, we determined the proportion of QDU patients who might have been evaluated in a less rapid, non-QDU setting.
