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.

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.

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.
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.
Li La Sr MnO thin films of various compositions (,,) have been grown using pulsed laser deposition. The compositions of the films have been studied as a function of deposition temperature, target-to-substrate distance and deposition pressure with respect to different cation ratios of the targets by inductively coupled plasma mass spectrometry. When growing multi-elemental oxide thin films containing lithium (with its large mass difference to other elements), lithium loss is most probably inevitable.

Intraprocedural tip location by intracavitary electrocardiography was not feasible because the patient had atrial fibrillation; intraprocedural tip location by ultrasound (using the so-called "bubble test") showed that the tip was not in the superior vena cava or in the right atrium. A post-procedural chest X-ray confirmed the malposition but could not precise the location of the tip.

Drug abuse (cannabis, cocaine, opiates, and synthetic drugs) is an increasing phenomenon, especially in the younger population, thus leading to more cases of intoxication requiring evaluation in the emergency department and subsequent hospitalization. In 2017, 34.2% of students reported having used an illegal psychoactive substance in their lifetime, while 26% reported having done so over the past year.

Methods: After PICC placement, a skin swab of the exit site was taken and cultured.
Lung ultrasound (LUS) has recently been advocated as an accurate tool to diagnose coronavirus disease 2019 (COVID-19) pneumonia. However, reports on its use are based mainly on hypothesis studies, case reports or small retrospective case series, while the prognostic role of LUS in COVID-19 patients has not yet been established. We conducted a prospective study aimed at assessing the ability of LUS to predict mortality and intensive care unit admission of COVID-19 patients evaluated in a tertiary level emergency department.

This can lead to many problems in terms of patient discomfort, increase of cost, and prolonged treatment time.
Objectives: This study aimed to reduce the number of attempts needed for a short-cannula insertion or preventing insertion of a central vascular access by placing an ultrasound-guided long cannula during the emergency department visit.

With our study, we searched the medical literature to find magnesium (Mg) correlation with Emergency situations or its use in Emergency Medicine. Our aim is to fill the gap that we find in our daily routine between Mg studies on its role in Emergency and the real conception that doctors have of it in medical practice. We searched the literature for terms as magnesium or magnesium sulphate, magnesium in emergency, eclampsia, arrhythmias, acute asthma exacerbation, magnesium, and pediatric population.

The aim of this study is to propose an easy clinical score to stratify the need of CCT in emergency department (ED) patients with suspect non-traumatic intracranial pathology.
Methods: We retrospectively evaluated patients presenting to the ED for neurological deficit, postural instability, acute headache, altered mental status, seizures, confusion, dizziness, vertigo, syncope, and pre-syncope.
Thin films of Y2Zr2O7 were grown via pulsed laser deposition (PLD) on substrates of MgO(110), Al2O3(0001) and Al2O3(11[combining macron]02). Electrical properties were investigated via electrical impedance spectroscopy. Unexpectedly, the ionic conductivity is not affected by the microstructure; only minor differences in conductivities and activation energies were measured between epitaxial thin films (on MgO) and textured thin films (on Al2O3, both orientations).

Keeping the total thickness of the heterostructures constant, the number of ceria-zirconia bilayers was increased while reducing the thickness of each layer. At each interface Ce was found primarily in the reduced, 3+ oxidation state in a layer extending about 2 nm from the interface.

Highly localized cerium reduction at the film-substrate interfaces is revealed by atomically resolved valence EELS mapping using C aberration-corrected scanning transmission electron microscopy. The chemical profiles reveal interdiffusion of Ce, (Gd), Y, Zr, forming an intermixing zone at the interface 7-9 (1 1 1) lattice planes wide.

We searched MEDLINE, EMBASE and Cochrane databases for case-control studies comparing SSR absence frequency and latency between patients with MS and healthy controls. Thirteen eligible studies including 415 MS patients and 331 healthy controls were identified.

The systematic study of the ionic transport properties of epitaxial YZrO films with defective fluorite structure reveals an enhanced oxygen vacancy conductivity at the interface between the films and the MgO(110) substrate, which is characterized by a high density of misfit dislocations. This beneficial effect is discussed in terms of space-charge and mobility effects.

The aim of this study was i) to evaluate thyroid effects of exposure to mancozeb, a fungicide widely used in agriculture, in a sample of Italian grapevine workers, and ii) to verify whether the iodine intake may modulate the risk of thyroid disruption due to the mancozeb metabolite ethylenthiourea (ETU).
Methods: One hundred seventy-seven occupationally exposed male workers (29 from Chianti, a mild iodine deficient area, and 148 from Bolzano an iodine sufficient province) and 74 non-occupationally exposed male controls (34 from Chianti and 40 from Bolzano) were enrolled in the study.

Diclofenac is the most widely prescribed non-steroidal anti-inflammatory drug worldwide. Data collected during the last 10 years reported a dose-duration dependent increasing of cardiovascular risk associated with the use of diclofenac, supporting the evidence of a close association with the degree of COX-2 inhibition achieved in vivo. Nevertheless, the amplitude of cardiovascular risk associated with the administration of diclofenac at low doses and for the short-term duration is still poorly defined.

Moreover, pain-killers prescriptions are usually related to the medical examination, leading to a delay in its administration, thus worsening the patient's quality of life. With our study, we want to define and validate a systematic and homogeneous approach to analgesic drugs administration, testing a new therapeutic algorithm in terms of earliness, safety, and efficacy.
