Diaphragmatic ultrasound evaluation in acute heart failure: clinical and functional associations.

Heart failure patients often experience respiratory symptoms due to diaphragmatic involvement, but the diaphragmatic motion in heart failure remains understudied. This research aimed to investigate the correlation between ultrasonographically assessed diaphragmatic motion and thickness with cardiac performance indexes in an emergency setting. Seventy-two acutely decompensated heart failure patients and 100 non-heart failure individuals were enrolled.

The specialized pro-resolving lipid mediator Protectin D1 affects macrophages differentiation and activity in Adult-onset Still's disease and COVID-19, two hyperinflammatory diseases sharing similar transcriptomic profiles.

Introduction: COVID-19 and autoinflammatory diseases, such as Adult-onset Still's Disease (AOSD), are characterized by hyperinflammation, in which it is observed massive production and uncontrolled secretion of pro-inflammatory cytokines. The specialized pro-resolving lipid mediators (SPMs) family is one the most important processes counteracting hyperinflammation inducing tissue repair and homeostasis restoration. Among SPMs, Protectin D1 (PD1) is able to exert antiviral features, at least in animal models.

The similar expression of both ferritin and scavenger receptors activation genes in patients with COVID19 and AOSD support their role in the pathogenesis of these diseases and identify a common mechanism at the basis of the "hyperferritinemic syndromes".

A role for COVID19 in "hyperferritinemic syndromes" has been proposed based on its clinical and serological characteristics and its similarities with AOSD. To better understand the molecular pathways responsible of these similarities, we evaluated in the PBMCs of 4 active AOSD patients, 2 COVID19 patients with ARDS, and 2 HCs the expression of genes associated with iron metabolisms, with monocyte/macrophages activation, and finally with NETs formation.

SARS-CoV-2 Variants in COVID-19 Disease: A Focus on Disease Severity and Vaccine Immunity in Patients Admitted to the Emergency Department.

Tracking SARS-CoV-2 variants along with vaccinations are fundamental for severe COVID-19 disease prevention. A study was performed that focused on 43 patients with the SARS-CoV-2 infection who were admitted to the Emergency Department. RT-PCR-positive nasopharyngeal samples were sequenced using the MiSeq II system for variant detection.

Incidence and Outcome of Pneumomediastinum in Non-ICU Hospitalized COVID-19 Patients.

Objectives: Pneumomediastinum (PNM) is a rare complication of mechanical ventilation, but its reported occurrence in patients with acute respiratory distress syndrome secondary to COVID-19 is significant. The objective is to determine the incidence, risk factors, and outcome of PNM in non-ICU hospitalized patients with severe-to-critical COVID-19 pneumonia.

Design: Retrospective observational study.

Long peripheral cannula in COVID-19 patients: 769 catheter days experience from a semi-intensive respiratory COVID unit.

Background: In the daily management of peripheral venous access, the health emergency linked to the COVID-19 pandemic led to re-examining the criteria for choosing, positioning and maintaining the different types of peripheral venous access.

Objectives: This study aimed to observe the dwell time of long peripheral cannula (LPC, also known as ) in patients affected by COVID 19 related pneumonia. The secondary objective is to study any complications due to mini-midline insertion.

High value of mid-regional proadrenomedullin in COVID-19: A marker of widespread endothelial damage, disease severity, and mortality.

The widespread endothelial damage due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may lead to a disruption of the adrenomedullin (ADM) system responsible for vascular leakage, increased inflammatory status, and microvascular alteration with multi-organs dysfunction. The aim of this study was to evaluate the role of mid-regional proadrenomedullin (MR-proADM) as a marker of SARS-CoV2 related widespread endothelial damage, clinically identified by organs damage, disease severity and mortality. Patients with SARS-CoV-2 infection has been prospectively enrolled and demographic characteristic, clinical and laboratory data has been evaluated.
