Implementation of the WHO standards to assess the quality of care for children with acute diarrhoea: findings of a multicentre study (CHOICE) in Italy.

Background: There is no documented experience in the use of the WHO standards for improving the quality of care (QOC) for children at the facility level. We describe the use of 10 prioritised WHO-Standard-based Quality Measures to assess QOC for children with acute diarrhoea (AD) in Italy.

Methods: In a multicentre observational study in 11 paediatric emergency departments with different characteristics and geographical location, we collected data on 3061 children aged 6 months to 15 years with AD and no complications.

Giant Rashba-splitting of one-dimensional metallic states in Bi dimer lines on InAs(100).

Bismuth produces different types of ordered superstructures on the InAs(100) surface, depending on the growth procedure and coverage. The (2 × 1) phase forms at completion of one Bi monolayer and consists of a uniformly oriented array of parallel lines of Bi dimers. Scanning tunneling and core level spectroscopies demonstrate its metallic character, in contrast with the semiconducting properties expected on the basis of the electron counting principle.

Spin-Dependent ππ^{*} Gap in Graphene on a Magnetic Substrate.

We present a detailed analysis of the electronic properties of graphene/Eu/Ni(111). By using angle- and spin-resolved photoemission spectroscopy and ab initio calculations, we show that the intercalation of Eu in the graphene/Ni(111) interface gives rise to a gapped freestanding dispersion of the ππ^{*} Dirac cones at the K[over ¯] point with an additional lifting of the spin degeneracy due to the mixing of graphene and Eu states. The interaction with the magnetic substrate results in a large spin-dependent gap in the Dirac cones with a topological nature characterized by a large Berry curvature and a spin-polarized Van Hove singularity, whose closeness to the Fermi level gives rise to a polaronic band.

Case Report: An unusual case of a transposition of the great arteries with a double aortic arch: a highly complex fetal diagnosis with an unpredictable outcome.

Published data estimate the prevalence of the vascular ring at approximately 7 per 10,000 live births. The association of a double aortic arch with a D-transposition of the great arteries has been rarely described in the literature. In this study, we report the prenatal diagnosis of a 28-year-old woman.

Doping dependent intrinsic magnetization in silicon in Ni/Si heterostructures.

This investigation delves into the complex interaction at metal-semiconductor interfaces, highlighting the magnetic proximity effect in Ni/Si interfaces through systematic X-ray magnetic circular dichroism (XMCD) studies at Ni and Si edges. We analyzed two Ni/Si heterostructures with differing semiconductor doping, uncovering a magnetic proximity effect manifesting as equilibrium magnetization in the semiconductor substrate induced by the adjacent Ni layer. Our results display distinct magnetization signs corresponding to the doping levels: low-doped samples show parallel alignment to the Ni layer, while high-doped samples align antiparallel, indicating a nuanced interplay of underlying magnetization mechanisms.

Alcohol Vapor Sensor Based on Quasi-2D NbO Derived from Oxidized NbCT MXenes.

MXenes are two-dimensional (2D) materials with a great potential for sensor applications due to their high aspect ratio and fully functionalized surface that can be tuned for specific gas adsorption. Here, we demonstrate that the NbCT-based sensor exhibits high performance towards alcohol vapors at temperatures up to 300-350 °C, with the best sensitivity towards ethanol. We attribute the observed remarkable chemiresistive effect of this material to the formation of quasi-2D NbO sheets as the result of the oxidation of Nb-based MXenes.

Anorectal malformations (ARM) and VACTERL association and severity of congenital heart diseases (CHD): Experience of 396 consecutive patients in a tertiary center.

Objective: Congenital heart diseases (CHD) are the most frequently associated anomalies with anorectal malformations (ARM). Nevertheless, many specific aspects of CHD in ARM patients have yet to be studied. The aims of this study were to evaluate the prevalence and distribution of CHD in neonates-infants with ARM, and to explore whether the severity of ARM, and the presence of VACTERL association, had an impact on CHD rate, severity, and timing at first cardiac surgery.

Electronic Band Engineering of Two-Dimensional Kagomé Polymers.

Two-dimensional conjugated polymers (2DCPs) are an emerging class of materials that exhibit properties similar to graphene yet do not have the limitation of zero bandgap. On-surface synthesis provides exceptional control on the polymerization reaction, allowing tailoring properties by choosing suitable monomers. Heteroatom-substituted triangulene 2DCPs constitute a playing ground for such a design and are predicted to exhibit graphene-like band structures with high charge mobility and characteristic Dirac cones in conduction or valence states.

Unidirectional Nano-modulated Binding and Electron Scattering in Epitaxial Borophene.

A complex interplay between the crystal structure and the electron behavior within borophene renders this material an intriguing 2D system, with many of its electronic properties still undiscovered. Experimental insight into those properties is additionally hampered by the limited capabilities of the established synthesis methods, which, in turn, inhibits the realization of potential borophene applications. In this multimethod study, photoemission spectroscopies and scanning probe techniques complemented by theoretical calculations have been used to investigate the electronic characteristics of a high-coverage, single-layer borophene on the Ir(111) substrate.

Unraveling the optoelectronic properties of CoSb intrinsic selective solar absorber towards high-temperature surfaces.

The combination of the ability to absorb most of the solar radiation and simultaneously suppress infrared re-radiation allows selective solar absorbers (SSAs) to maximize solar energy to heat conversion, which is critical to several advanced applications. The intrinsic spectral selective materials are rare in nature and only a few demonstrated complete solar absorption. Typically, intrinsic materials exhibit high performances when integrated into complex multilayered solar absorber systems due to their limited spectral selectivity and solar absorption.

Interplay between magnetic order and electronic band structure in ultrathin GdGe metalloxene films.

Dimensionality can strongly influence the magnetic structure of solid systems. Here, we predict theoretically and confirm experimentally that the antiferromagnetic (AFM) ground state of bulk gadolinium germanide metalloxene, which has a quasi-layered defective GdGe structure, is preserved in the ultrathin film limit. calculations demonstrate that ultrathin GdGe films present in-plane intra-layer ferromagnetic coupling and AFM inter-layer coupling in the ground state.

Physical Delithiation of Epitaxial LiCoO Battery Cathodes as a Platform for Surface Electronic Structure Investigation.

We report a novel delithiation process for epitaxial thin films of LiCoO(001) cathodes using only physical methods, based on ion sputtering and annealing cycles. Preferential Li sputtering followed by annealing produces a surface layer with a Li molar fraction in the range 0.5 < < 1, characterized by good crystalline quality.

Giant and Tunable Out-of-Plane Spin Polarization of Topological Antimonene.

Topological insulators are bulk insulators with metallic and fully spin-polarized surface states displaying Dirac-like band dispersion. Due to spin-momentum locking, these topological surface states (TSSs) have a predominant in-plane spin polarization in the bulk fundamental gap. Here, we show by spin-resolved photoemission spectroscopy that the TSS of a topological insulator interfaced with an antimonene bilayer exhibits nearly full out-of-plane spin polarization within the substrate gap.

Degradation and Self-Healing of FAPbBr Perovskite under Soft-X-Ray Irradiation.

The extensive use of perovskites as light absorbers calls for a deeper understanding of the interaction of these materials with light. Here, the evolution of the chemical and optoelectronic properties of formamidinium lead tri-bromide (FAPbBr ) films is tracked under the soft X-ray beam of a high-brilliance synchrotron source by photoemission spectroscopy and micro-photoluminescence. Two contrasting processes are at play during the irradiation.

Nearly-freestanding supramolecular assembly with tunable structural properties.

The synthesis and design of two-dimensional supramolecular assemblies with specific functionalities is one of the principal goals of the emerging field of molecule-based electronics, which is relevant for many technological applications. Although a large number of molecular assemblies have been already investigated, engineering uniform and highly ordered two-dimensional molecular assemblies is still a challenge. Here we report on a novel approach to prepare wide highly crystalline molecular assemblies with tunable structural properties.

Synchrotron radiation photoemission spectroscopy of the oxygen modified CrCl surface.

We investigate the experimentally challenging CrCl surface by photon energy dependent photoemission (PE). The core and valence electrons after cleavage of a single crystal, either in a ultra-high vacuum (UHV) or in air, are studied by keeping the samples at 150 °C, aiming at confirming the atomic composition with respect to the expected bulk atomic structure. A common spectroscopic denominator revealed by data is the presence of a stable, but only partially ordered Cl-O-Cr surface.

Prenatal prediction of Shone's complex. The role of the degree of ventricular disproportion and speckle-tracking analysis.

Objectives: Shone's complex (SC) is characterized by sequential obstructions of left ventricular (LV) inflow and outflow. It can be associated with poor long-term prognosis when compared to Simple-Aortic Coarctation (S-CoA). We aimed to assess whether the degree of ventricular disproportion and 2D-speckle-tracking echocardiography (2D-STE) could improve the accuracy of prenatal prediction of SC.

Facile Electron Transfer in Atomically Coupled Heterointerface for Accelerated Oxygen Evolution.

An efficient and cost-effective approach for the development of advanced catalysts has been regarded as a sustainable way for green energy utilization. The general guideline to design active and efficient catalysts for oxygen evolution reaction (OER) is to achieve high intrinsic activity and the exposure of more density of the interfacial active sites. The heterointerface is one of the most attractive ways that plays a key role in electrochemical water oxidation.

Echocardiographic diagnosis of a large coronary artery fistula in a newborn.

Coronary artery fistula (CAF) is a rare cause of heart murmur in newborns, with a very heterogeneous clinical presentation and unpredictable natural history. We described the case of a large neonatal CAF in an asymptomatic newborn. The patient did not show any symptoms of heart failure during a three-month follow-up.

Early recognition of child abuse through screening indicators at the emergency department: experience of a tertiary urban pediatric hospital.

Background: Emergency Departments play a pivotal role in detecting cases of child abuse. Despite the efforts made in the past decades on the need for a screening method for the early detection of abuse victims, a unique instrument shared by the international scientific community has not been made. These instruments should be able to help recognizing whether it is necessary to further investigate the child's condition.
