Pathological Findings Associated With SARS-CoV-2 on Postmortem Core Biopsies: Correlation With Clinical Presentation and Disease Course.

Background: Autopsies can shed light on the pathogenesis of new and emerging diseases.

Aim: To describe needle core necropsy findings of the lung, heart, and liver in decedents with COVID-19.

Material: Cross-sectional study of needle core necropsies in patients who died with virologically confirmed COVID-19.

Conventional and advanced MRI evaluation of brain vascular malformations.

Vascular malformations (VMs) of the central nervous system (CNS) include a wide range of pathological conditions related to intra and extracranial vessel abnormalities. Although some VMs show typical neuroimaging features, other VMs share and overlap pathological and neuroimaging features that hinder an accurate differentiation between them. Hence, it is not uncommon to misclassify different types of VMs under the general heading of arteriovenous malformations.

Ocrelizumab in Multiple Sclerosis: A Real-World Study From Spain.

The aim of this study was to describe the tolerability, safety, and effectiveness of ocrelizumab for primary progressive multiple sclerosis (PPMS) and relapsing multiple sclerosis (RMS) in a clinical practice setting. In this retrospective observational study, we analyzed clinical and MRI data in all patients with PPMS and RMS who had received at least one infusion of ocrelizumab in two health areas in south-eastern Spain. Patients involved in any ocrelizumab trial and those patients with a follow-up shorter than 6 months were excluded.

Prognostic value of chest radiographs in patients with acute heart failure: the Radiology in Acute Heart Failure (RAD-ICA) study.

Objectives: To determine whether chest radiographs can contribute to prognosis in patients with acute heart failure (AHF).

Material And Methods: Consecutive patients with AHF were enrolled by the participating emergency departments. Radiographic variables assessed were the presence or absence of evidence of cardiomegaly and pleural effusion and the pulmonary parenchymal pattern observed (vascular redistribution, interstitial edema, and/or alveolar edema).
