L’échelle d’impact des problèmes actuels de comportement (IMPAC) est un outil visant à mesurer l’impact des comportements problématiques chez les personnes ayant subi une lésion cérébrale acquise. Cette mesure évalue l’impact des comportements sur la personne cérébrolésée et son entourage selon cinq dimensions : les relations significatives, l’intégrité psychologique, l’accès aux services, l’intégrité physique et les interventions dispensées. Mis au point par des intervenants spécialisés en trouble du comportement chez la clientèle cérébrolésée, cet outil a fait l’objet d’une série de trois études de validation de contenu. Celles-ci ont été menées auprès d’experts et de professionnels du réseau de la réadaptation en déficience physique. Les résultats ont démontré que l’échelle IMPAC possède une validité de contenu satisfaisante, c’est-à-dire que les dimensions ciblées et les niveaux d’impact décrits pour chacune d’elles reposent sur des critères clairement définis et reconnus comme tels par les experts. L’échelle IMPAC constitue donc un instrument potentiellement utile pour les cliniciens qui souhaitent évaluer de manière objective l’impact des comportements problématiques d’un usager, et ainsi contribuer à guider les interventions prioritaires et à éclairer les décisions d’orientation vers des ressources d’hébergement ou des services spécialisés.

Authors: Matte-Landry Alexandra , Collin-Vézina Delphine 
Published: May 2021

Les enfants et les adolescents hébergés en centre de réadaptation (CR) ou en foyer de groupe (FG) constituent une population vulnérable chez qui l’utilisation de mesures restrictives, telles que la contention, l’isolement ou le retrait est préoccupante. L’objectif général de la présente étude est de mieux comprendre l’utilisation de ces mesures afin d’améliorer les pratiques cliniques auprès des jeunes en CR et en FG.

Méthode

: Des données clinico-administratives ont été extraites sur l’utilisation de mesures restrictives auprès de 324 jeunes (29 unités, 10 centres/régions). Une analyse de profil latent a été utilisée afin d’identifier des sous-groupes de jeunes quant aux mesures restrictives. Afin de déterminer quelles caractéristiques individuelles (âge, sexe, appartenance ethnique, motif de prise en charge) et environnementales (durée du séjour, type d’unité, spécialisation de l’unité, mandat légal de l’unité [LPJ vs. LSJPA]) prédisaient l’appartenance aux profils, des régressions logistiques ont été utilisées.

Résultats

: Près de la moitié des jeunes (48,1%) n’ont expérimenté aucune mesure restrictive pendant la période de six mois étudiée. Parmi les jeunes qui en ont vécu au moins une, deux profils latents ont été trouvés. Plusieurs caractéristiques individuelles, mais surtout environnementales, prédisent d’une part, le fait d’expérimenter ou non une mesure, et, d’autre part, l’appartenance à l’un des deux profils chez les jeunes qui ont expérimenté au moins une mesure.

Conclusion

: La présente étude a permis d’identifier des facteurs de risque individuels, mais surtout environnementaux, associés au fait de vivre des mesures restrictives.
Complex Regional Pain Syndrome: Impairment Assessment
Authors: Feinberg Steven D. , Brooks Charles N. , Brigham Christopher R. 
Published: May 2021

Abstract
Complex regional pain syndrome (CRPS) is characterized by chronic spontaneous and/or evoked regional pain disproportionate in severity, distribution, and/or duration to that typically experienced after a similar injury or illness. The pain may also begin without a known precipitant. While various authors have questioned the validity of the diagnosis, physicians will be asked to perform impairment ratings on patients diagnosed with CRPS. Hence, it is important to understand the issues associated with this syndrome; the diagnostic criteria for it, including the need to rule out other diagnoses that may explain the patient's presentation; and how to rate CRPS. The AMA Guides to the Evaluation of Permanent Impairment, Fifth Edition, provides approaches to assessing CRPS impairment that are refined in the Sixth Edition.

AbstractFlexible and stretchable antennas are important for wireless communication using wearable and implantable devices to address mechanical mismatch at the tissue–device interface. Emerging technologies of liquid‐metal‐based stretchable electronics are promising approaches to improve the flexibility and stretchability of conventional metal‐based antennas. However, existing methods to encapsulate liquid metals require monolithically thick (at least 100 µm) substrates, and the resulting devices are limited in deformability and tissue‐adhesiveness. To overcome this limitation, fabrication of microchannels by direct ink writing on a 7 µm‐thick elastomeric substrate is demonstrated, to obtain liquid metal microfluidic antennas with unprecedented deformability. The fabricated wireless light‐emitting device is powered by a standard near‐field‐communication system (13.56 MHz, 1 W) and retained a consistent operation under deformations including stretching (>200% uniaxial strain), twisting (180° twist), and bending (3.0 mm radius of curvature) while maintaining a high quality factor (q > 20). Suture‐free conformal adhesion of the polydopamine‐coated device to ex vivo animal tissues under mechanical deformations is also demonstrated. This technology offers a new capability for the design and fabrication of wireless biomedical devices requiring conformable tissue‐device integration toward minimally invasive, imperceptible medical treatments.

AbstractElectronic charge rearrangement between components of a heterostructure is the fundamental principle to reach the electronic ground state. It is acknowledged that the density of state distribution of the components governs the amount of charge transfer, but a notable dependence on temperature is not yet considered, particularly for weakly interacting systems. Here, it is experimentally observed that the amount of ground‐state charge transfer in a van der Waals heterostructure formed by monolayer MoS2 sandwiched between graphite and a molecular electron acceptor layer increases by a factor of 3 when going from 7 K to room temperature. State‐of‐the‐art electronic structure calculations of the full heterostructure that accounts for nuclear thermal fluctuations reveal intracomponent electron–phonon coupling and intercomponent electronic coupling as the key factors determining the amount of charge transfer. This conclusion is rationalized by a model applicable to multicomponent van der Waals heterostructures.

AbstractOwing to their dynamic nature and ordered architecture, supramolecular materials strikingly resemble organic components of living systems. Although short‐peptide self‐assembled nanostructured hydrogels are regarded as intriguing supramolecular materials for biotechnology, their application is often limited due to their low stability and considerable challenge of combining other desirable properties. Herein, a di‐Fmoc‐based hydrogelator containing the cell‐adhesive Arg–Gly–Asp (RGD) fragment that forms a mechanically stable, self‐healing hydrogel is designed. Molecular dynamics simulation reveals the presence of RGD segments on the surface of the hydrogel fibers, highlighting their cell adherence capacity. Aiming to impart conductivity, the 3D network of the hydrogel is further nanoengineered by incorporating polyaniline (PAni). The composite hydrogels demonstrate semiconductivity, excellent antibacterial activity, and DNA binding capacity. Cardiac cells grown on the surface of the composite hydrogels form functional synchronized monolayers. Taken together, the combination of these attributes in a single hydrogel suggests it as an exceptional candidate for functional supramolecular biomaterial designed for electrogenic tissue engineering.

AbstractIn this study, the electronic properties and chemical stability of the Cu/CH3NH3PbI3 interface are investigated in situ by a combination of X‐ray photoelectron spectroscopy and synchrotron radiation photoemission spectroscopy (SRPES). The morphology of Cu deposited perovskite surface is monitored by scanning electron microscopy. The results show that the Cu/CH3NH3PbI3 interface is very stable and no chemical reaction between Cu and the perovskite takes place. Moreover, a 0.45 eV interface dipole and a 0.15 eV upward band bending are obtained at the Cu/CH3NH3PbI3 interface. Based on these fundamental findings, a prototype of Cu/CH3NH3PbI3/NiOx/indium tin oxide solar cell device is constructed to check the power conversion efficiency (PCE) and device stability. Although no electron transport material is used in this device, it still exhibits decent performance. The PCE of the device reaches up to 9.99% and remains almost unchanged over a long‐time (49 d) storage in a N2‐filled glovebox. Through this study it is demonstrated that fundamental understanding of the interfacial structure of a perovskite solar cell is essential in pursuit of rational design of superior perovskite solar cells, and moreover, Cu is a promising electrode candidate for perovskite solar cells.
Self‐Healing Superhydrophobic Surfaces: Healing Principles and Applications
Authors: Xiang Siyuan , Liu Wendong 
Published: May 2021

AbstractSuperhydrophobic surfaces have already been applied in anti‐fouling, water‐oil separation, liquid transportation, etc. Surfaces can be defined as superhydrophobic surfaces once they can support a water droplet with its spherical shape maintained and accompanied by an apparent contact angle larger than 150° and a rolling‐off angle below 10°. Such water repellent property is achieved by the synergetic action of hierarchical structures and the low‐surface energy of the substances constructing the surface. Structures with high aspect ratio always perform good superhydrophobicity. However, they are usually with poor mechanical stability. Since durability is one of the essential factors for practical use, exploiting robust superhydrophobic surfaces has attracted tremendous interest. During the past decade, great effort has been made in developing self‐healing superhydrophobic surfaces to improve the potential practice and broaden the application fields. An overview of the recent development of self‐healing superhydrophobic surfaces is provided in this review. The focus here is particularly on the fabrication process based on specific healing mechanisms and possible applications. Finally, an outlook on future fabrication techniques for durable superhydrophobic surfaces is presented.

AbstractLead‐free halide double perovskite Cs2AgInCl6 has attracted great attention due to its highly efficient luminescence and excellent stability. However, the parity forbidden electronic transition limits further applications in lighting and display fields. In this work, Cs2AgInCl6 nanocrystals (NCs) are synthesized by injecting trimethyl chlorosilane into the dissolved precursors at 180 °C and the as‐synthesized Cs2AgInCl6 NCs exhibit a weak orange emission peak at 570 nm with a photoluminescence quantum yield (PLQY) of 1.5%. In order to break the parity forbidden transition, various amounts of Na are alloyed into Cs2AgInCl6 NCs, resulting a peak PLQY of 13.4% in Cs2Na0.6Ag0.4InCl6 NCs. Then Mn2+ doped Cs2NaxAg1−xInCl6 NCs are synthesized in the same approach, in which the highest PLQY can be enhanced up to 36%. As a result, a redshifted photoluminescence emission peak at 625 nm is observed, which derives from the 4T1→6A1 transition of Mn2+ that is related to the ultrafast energy transfer from self‐trapped exciton states to the 4T1 excited state of Mn2+.
Cu–Ferrocene‐Functionalized CaO2 Nanoparticles to Enable Tumor‐Specific Synergistic Therapy with GSH Depletion and Calcium Overload

Published: May 2021

AbstractThe conversion of endogenous H2O2 into toxic hydroxyl radical (•OH) via catalytic nanoparticles is explored for tumor therapy and received considerable success. The intrinsic characteristics of microenvironment in tumor cells, such as limited H2O2 and overexpressed glutathione (GSH), hinder the intracellular •OH accumulation and thus weaken therapeutic efficacy considerably. In this study, fine CaO2 nanoparticles with Cu–ferrocene molecules at the surface (CaO2/Cu–ferrocene) are successfully designed and synthesized. Under an acidic condition, the particles release Ca2+ ions and H2O2 in a rapid fashion, while they can remain stable in neutral. In addition, agitated production of •OH occurs following the Fenton reaction of H2O2 and ferrocene molecules, and GSH is consumed by Cu2+ ions to avoid the potential •OH consumption. More interestingly, in addition to the exogenous Ca2+ released by the particles, the enhanced •OH production facilitates intracellular calcium accumulation by regulating Ca2+ channels and pumps of tumor cells. It turns out that promoted •OH induction and intracellular calcium overload enable significant in vitro and in vivo antitumor phenomena.

AbstractSolar energy is a key sustainable energy resource, and materials with optimal properties are essential for efficient solar energy‐driven applications in photocatalysis. Metal–organic frameworks (MOFs) are excellent platforms to generate different nanocomposites comprising metals, oxides, chalcogenides, phosphides, or carbides embedded in porous carbon matrix. These MOF derived nanocomposites offer symbiosis of properties like high crystallinities, inherited morphologies, controllable dimensions, and tunable textural properties. Particularly, adjustable energy band positions achieved by in situ tailored self/external doping and controllable surface functionalities make these nanocomposites promising photocatalysts. Despite some progress in this field, fundamental questions remain to be addressed to further understand the relationship between the structures, properties, and photocatalytic performance of nanocomposites. In this review, different synthesis approaches including self‐template and external‐template methods to produce MOF derived nanocomposites with various dimensions (0D, 1D, 2D, or 3D), morphologies, chemical compositions, energy bandgaps, and surface functionalities are comprehensively summarized and analyzed. The state‐of‐the‐art progress in the applications of MOF derived nanocomposites in photocatalytic water splitting for H2 generation, photodegradation of organic pollutants, and photocatalytic CO2 reduction are systemically reviewed. The relationships between the nanocomposite properties and their photocatalytic performance are highlighted, and the perspectives of MOF derived nanocomposites for photocatalytic applications are also discussed.

Published: May 2021

AbstractLithium‐sulfur (Li‐S) batteries, as part of the post‐lithium‐ion batteries (post‐LIBs), are expected to deliver significantly higher energy densities. Their power densities, however, are today considerably worse than that of the LIBs, limiting the Li‐S batteries to very few specific applications that need low power and long working time. With the rapid development of single cell components (cathode, anode, or electrolyte) in the last few years, it is expected that an integrated approach can maximize the power density without compromising the energy density in a Li‐S full cell. Here, this goal is achieved by using a novel biomass porous carbon matrix (PCM) in the anode, as well as N‐Co9S8 nanoparticles and carbon nanotubes (CNTs) in the cathode. The authors' approach unlocks the potential of the electrodes and enables the Li‐S full pouch cells with unprecedented power densities and energy densities (325 Wh kg−1 and 1412 W kg−1, respectively). This work addresses the problem of low power densities in the current Li‐S technology, thus making the Li‐S batteries a strong candidate in more application scenarios.

Published: May 2021

AbstractBlack phosphorus (BP), an emerging crystal material with prominent features such as high carrier mobility and easily modulated band structure, fills the deficiencies of graphene and transition metal dichalcogenides. It has become a key component of 2D materials. The biggest advantage of BP is reflected in the fixed and direct energy band structure. Starting from the introduction of BP's crystal structure, this work reviews the important role of doping strategies, van der Waals heterojunction, and contact engineering thickness control technology in bandgap adjustment and performance improvement of BP field effect transistors. The focus is to put on the enhanced performance of electronic devices in high mobility, fast response speed, wide spectral range, low power consumption, and stronger stability caused by bandgap modulation. These methods cover from advanced technology to a wide range of electrical and optoelectronic progress in recent years, showing a booming development trend. In addition, considering the breakthrough of BP in new physics and application prospects, the potential applications of the active field are highlighted in this work.

AbstractGaucher disease (GD), one of the most common lysosomal disorders, is caused by deficiency of β‐glucocerebrosidase. Based on the presence and severity of neurological complications, GD is classified into types I, II (the most severe form), and III. Abnormalities in systemic markers of vitamin B12 (B12) metabolism have been reported in GD type I patients, suggesting a higher prevalence of B12 deficiency in these patients. A 2‐month‐old male with GD type II was admitted to the hospital presenting jaundice, hepatosplenomegaly, and ichthyosis. At admission, cholestasis and ascites, abnormal liver function enzymes, prolonged prothrombin time, and high levels of B12 were confirmed. Analysis of biomarkers of B12 status revealed elevated B12 and holo‐transcobalamin (holo‐TC) levels. The B12 profile found in our patient is the opposite to what is described for GD type I patients. Holo‐TC may increase in inflammatory states or due to liver diseases. In GD, the accumulation of glucocerebroside may be a trigger that initiates a systemic inflammatory reaction, characterized by macrophage activation. We suggest higher levels of holo‐TC could be associated with a more severe (neuronopathic) GD, and be a biomarker of GD type II.

Published: May 2021

AbstractIn this text, I will present reflections on the relationship between individual trauma and collective trauma and the consideration of the pandemic as both a natural and a social catastrophe in which damage to health is added to damage in the rupture of social and relational bonds. Vicissitudes that Argentine families, particularly those in Buenos Aires, went through during the compulsory lockdown and the work of psychoanalysts both in remote analysis with children and parents, as well as in interventions proposed for the community will be presented. Theoretical and conceptual descriptions will be offered together with examples from clinical material and community institutional experiences and collected data.
