Integration of LiTiO Crystalline Films on Silicon Toward High-Rate Performance Lithionic Devices.

The growth of crystalline Li-based oxide thin films on silicon substrates is essential for the integration of next-generation solid-state lithionic and electronic devices including on-chip microbatteries, memristors, and sensors. However, growing crystalline oxides directly on silicon typically requires high temperatures and oxygen partial pressures, which leads to the formation of undesired chemical species at the interface compromising the crystal quality of the films. In this work, we employ a 2 nm gamma-alumina (γ-AlO) buffer layer on Si substrates in order to grow crystalline thin films of LiTiO (LTO), a well-known active material for lithium-ion batteries.

Intravenous Magnesium Sulfate Reduces the Need for Antiarrhythmics during Acute-Onset Atrial Fibrillation in Emergency and Critical Care.

Several studies have suggested the potential role of Magnesium Sulfate (MgSO) for the treatment of Atrial Fibrillation (AF) but, in clinical practice, the use of magnesium is not standardized although it is largely used for the treatment of supraventricular arrhythmias. Objectives. We evaluated the role of MgSO infusion in association with flecainide in cardioversion of patients presenting in ED with symptomatic AF started less than 48 h before.

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.
