Published: June 2017

Estudo de caso qualitativo desenvolvido com o objetivo de identificar os conhecimentos e as necessidades de aprendizagem relacionados à enfermidade cardíaca em hipertensos submetidos à revascularização miocárdica. Os dados foram coletados por meio de entrevistas semi-estruturadas realizadas no domicílio de doze indivíduos. Observou-se que os sujeitos não imaginavam que o mal-estar, a dor no peito e no estômago pudessem ser um problema no coração. A maior parte não percebera o risco de desenvolver a doença cardíaca associado a fatores com os quais já convivia, como a hipertensão. Ao buscarem explicações para a doença cardíaca, muitos deles relataram que vivenciavam situações de estresse, ingeriam comidas gordurosas, fumavam, bebiam, não praticavam exercícios físicos, não iam ao médico e se preocupavam apenas com o trabalho e a provisão financeira da família. As necessidades de aprendizagem relacionaram-se à compreensão sobre as causas da coronariopatia e da hipertensão e os cuidados preventivos para lhes assegurar boa saúde e qualidade de vida. Os resultados mostraram a importância da utilização pelos profissionais de estratégias de educação em saúde que satisfaçam as necessidades de conhecimento dos indivíduos acerca do processo saúde e doença e que contribuam para que, efetivamente, eles incorporem às suas vidas atitudes que promovam saúde.
Nyungar of Southwestern Australia and Flinders: A Dialogue on Using Nyungar Intelligence to Better Understand Coastal Exploration
Authors: Collard Len , Bracknell Clint , Palmer David 
Published: June 2017

Abstract
Methods used to investigate the history of mapping the coastal areas of Australia have relied heavily on the journals, diaries, ship's logs, maps, and other accounts of European mariners available in the archival record. Although these records give some details of the part played by local Indigenous peoples, such texts by themselves are a far from reliable way to arrive at authoritative conclusions about Indigenous influence in coastal exploration. Taking the form of a dialogue, this article revisits archival material concerned with coastal exploration along the southern areas of what is now Western Australia from a fresh perspective, drawing out instances where the Nyungar took “center stage” and where mariners' perceptions were shaped by their interest in the Nyungar and Nyungar knowledge. It draws upon Nyungar methods for “reading” the history of contact along the southern coast, incorporating oral accounts, knowledge of the Nyungar language, and Nyungar place-names to “talk back” to the old texts.

AbstractObjectiveWe evaluated the effect of CHA2DS2‐VASc score and prior use of oral anticoagulants (OACs) on endovascular treatment (EVT) in patients with acute ischemic stroke and atrial fibrillation (AF).MethodsPatients with AF who received EVT in 353 centers in Japan (2018–2020) were included. The outcomes were symptomatic intracerebral hemorrhage (sICH), in‐hospital mortality, functional independence, and successful and complete reperfusion. The effects of CHA2DS2‐VASc score, its components, and prior use of OACs were assessed via a multiple logistic regression model.ResultsOf the 6984 patients, 780 (11.2%) used warfarin and 1168 (16.7%) used direct oral anticoagulants (DOACs) before EVT. Based on the CHA2DS2‐VASc score, 6046 (86.6%) presented a high risk (≥2 for males and ≥3 for females) while 938 (13.4%) had intermediate to low risks. Higher CHA2DS2‐VASc scores were associated with increased sICH, in‐hospital mortality, and decreased functional independence, regardless of prior OACs. For patients with a high‐risk category, prior DOACs increased the odds of successful and complete reperfusion (adjusted odds ratio [95% confidence interval (CI)], 1.27 [1.00–1.61] and 1.30 [1.10–1.53]). For those with integrated intermediate to low risks, neither prior warfarin nor DOAC affected the outcomes. Regardless of total CHA2DS2‐VASc scores, patients with congestive heart failure or left ventricular dysfunction, hypertension, age >75 years, or female benefited similarly from prior DOAC use.InterpretationPrior DOAC use for patients with high‐ and selected intermediate‐risk CHA2DS2‐VASc scores increased prevalence of successful and complete reperfusion. These findings may provide supplemental evidence to introduce preventive DOAC for patients with AF.

AbstractDesulfurization is a significant approach to producing clean fuel. The design of novel host–guest catalysts with multiple active sites at atomic‐ and nano‐scales, opens a new door to gain an ultrahigh synergistic performance for targeted applications. Herein, an in situ solvent‐free approach is conducted for synchronously implanting Pd single sites (PdSS) and nanoparticles (PdNP) into a novel Zr‐based metal–organic framework (Zr‐MOF). The optimal catalyst exhibits ultrahigh oxidative desulfurization (ODS) performance that can oxidize 1 000 ppm sulfur with diluted oxidant at 40 °C within 5 min. The turnover frequency of the catalyst at 40 °C reaches 774.7 h−1 which is 47.4 times higher than host Zr‐MOF and surpasses the most reported ODS catalysts. A substantial synergistic effect between PdSS and PdNP is responsible for the upgradation of ODS performance. Experimental and theoretical results indicate that PdSS in Zr‐MOF can readily absorb H2O2, and synergistically decompose H2O2 with the assistance of PdNP for accelerated generation of •OH radicals that dominates the ODS performance. This work provides a new solvent‐free way for in situ implanting synergistic catalytic sites into MOFs to upgrade their catalytic performance in targeted reactions.

Published: October 2024

AbstractThe Layer‐by‐Layer (LbL) strategy has emerged as a highly effective approach for enhancing the performance of organic photovoltaics (OPVs), notably boosting light harvesting and fill factor through spectral complementarity and morphology optimization. Crucially, the LbL processing strategy has been found to mitigate or overcome the decline in power conversion efficiency (PCE) during high‐speed blade coating. Despite these advancements, there remains a scarcity of research into the film‐formation process and the corresponding control strategies in high‐speed printing. A novel synergistic concentration‐temperature gradient control (SCTGC) strategy aimed at achieving high‐performance LbL‐type active layers at ultra‐fast coating speeds. This investigation reveals that both baseplate temperature and solution concentration exert a nonmonotonic regulatory influence on PCEs. Fine‐tuning the concentration gradient proves instrumental in balancing microfluidic competition within the wet film, thereby facilitating stable mass transport during the film formation process, and enhancing the high‐speed processability of the relevant OPV system. Additionally, the variations in crystallization kinetics under different temperatures are monitored. This work sheds light on the coating mechanism and film formation in high‐speed coating, highlighting the efficiency of the SCTGC method.

AbstractFused Filament Fabrication is a promising manufacturing technology for the circularity of space missions. Potential scenarios include in‐orbit applications to maximize mission life and to support long‐term exploration missions with in situ manufacturing and recycling. However, its adoption is restricted by the availability of engineering polymers displaying mechanical performance combined with resistance to space conditions. Here, a thermotropic Liquid Crystal Polymer (LCP) is reported as a candidate material with extrusion 3D printing. To expand its scope of applicability to structural parts for space applications, four different exposure conditions are studied: thermal cycling under vacuum, atomic oxygen, UV, and electron irradiations. While 1 MeV‐electron irradiation leads to a green coloration due to annealable color centers, the mechanical performance is only slightly decreased in dynamic mode. It is also found that increased printing temperature improves transverse strength and resistance to thermal cycling with the trade‐off of tensile stiffness and strength. Samples exposed to thermal cycling and the highest irradiation dose at lower printing temperatures still display a Young's modulus of 30 GPa and 503 MPa of tensile strength which is exceptionally high for a 3D‐printed polymer. For the types of exposure studied, overall, the results indicate that LCP 3D‐printed parts are well suited for space applications.

Published: October 2024

AbstractIonogels, as a novel class of environmentally friendly electronic materials, have received extensive attention. This study successfully prepared P(AM‐co‐AA) ionogel with optical transparency and flexibility via chemical polymerization. Experimental outcomes reveal that the dispersion of anions and cations within the ionogel is effectively controlled by the polymer network, resulting in distinct dispersive dielectric property, which is suitable for applications in electromagnetic metamaterials. Leveraging these properties, two distinct electromagnetic metamaterial devices are developed: An Ionogel‐based Broadband Absorber achieves over 90% absorption across 10.9–25.36 GHz, and An Ionogel‐based Frequency Selective Rasorber (FSR) transmits within 4.62–5.86 GHz, exhibiting minimal insertion loss −1.45 dB and achieves greater than 90% absorption from 13 to 17.8 GHz. High agreement between experimental results and simulations validates the feasibility of utilizing ionogel in electromagnetic metamaterial applications and introduces a novel paradigm and methodology for designing and fabricating flexible electromagnetic metamaterial devices.

Published: October 2024

AbstractControllable coordination and efficient sensitization of rare earth ions in polymer materials are key to achieving high‐performance optoelectronic polymers. By designing aromatic diamines, polyimides are synthesized with 1,10‐phenanthroline benzimidazole groups (PBG) in the polymer backbone. Utilizing the coordination between PBG and rare earth ions (Eu3⁺, Tb3⁺), polyimide‐rare earth complexes are formed and precisely characterized their structures. The unique coordination allows PBG to effectively sensitize Eu3⁺, resulting in efficient, long‐lived red emission. Furthermore, PBG maintains excellent coordination with Eu3⁺ in acidic environments, granting acid‐responsive color changes for data encryption. Importantly, PBG sensitization of Tb3⁺ enabled full‐spectrum emission (CIE coordinates: (0.31, 0.35)) within a single rare earth‐polyimide complex, due to electron transfer among the ions, ligands, and polymer. This leads to the design of a multi‐layer PLED device with an optimal external quantum efficiency of 0.43% for white light emission (CIE coordinates: (0.28, 0.34)). Through comparative theoretical and experimental analysis, the photophysical behavior of these coordinated polyimides is explained and explored their photoluminescent and electroluminescent properties. This research integrates the advantages of rare earth elements and polyimides, creating novel luminescent polymers with diverse optical applications, providing a new strategy for designing luminescent coordination polymers.

Published: October 2024

AbstractTo ensure a more accurate simulation of the wheel‐rail contact state in vehicle‐track interaction, a non‐iterative contact geometry determination algorithm is proposed. This algorithm decouples lateral movement and roll, independently calculates the minimum wheel‐rail gap on both sides, and overcomes the limitation of simultaneous wheel‐rail contact on both sides. It can be applied to single‐side and two‐side wheel‐rail separation problems. Additionally, by converting track irregularity and rail deformation into the reverse displacement of the wheel, it avoids real‐time calculation of the wheel‐rail spatial position, thereby improving calculation efficiency. The effectiveness of the algorithm is verified through Universal Mechanism software and field measurements. Subsequently, the influence of the measured wheel‐rail profile, rail cant, and rail gauge on the wheel‐rail contact characteristics is analyzed. Finally, vehicle shaking caused by track irregularity and wheel‐rail contact is examined from the perspective of wheel‐rail matching. The study demonstrates that the non‐iterative algorithm is suitable for online simulation by pre‐processing the contact geometry parameters. When the track gauge and rail cant increase, the distribution of wheel‐rail contact points becomes more concentrated. Furthermore, when the excitation frequency of wheel‐rail matching is close to the track irregularity excitation frequency, it causes vibration amplification, resulting in lateral vehicle shaking.

ObjectiveThe introduction of disease‐modifying therapies for multiple sclerosis (MS) has led to a deceleration of disease course over the years. Although decreased relapse rate constitutes a factor, the role of relapse‐associated worsening (RAW) and progression independent of relapse activity (PIRA) in MS course deceleration is still unclear.MethodsWe retrospectively examined long‐term Expanded Disability Status Scale (EDSS) progression in patients referred to the MS Center of Montichiari (Italy) and diagnosed with relapsing–remitting MS from 1980 to 2022. To isolate PIRA, we deducted all EDSS changes associated with relapses from overall EDSS change. We compared the relative contribution of PIRA and RAW to EDSS progression in patients diagnosed in different periods using mixed‐effects models.ResultsA total of 1,405 patients were included in the study, of whom 231 were diagnosed in 1980–1996 (pre‐treatment era), 577 in 1997–2008 (injectable disease‐modifying therapy era), and 597 after 2008 (oral drugs, monoclonal antibodies, and anti‐CD20 era). Across ages, both PIRA and RAW were reduced in patients diagnosed in more recent periods as compared with earlier periods. The average contribution of PIRA to overall EDSS progression was already predominant in patients diagnosed in 1980–1996 (78%) and in 1997–2008 (76%), but it was significantly increased (p = 0.0009) in patients diagnosed in later years (87%).InterpretationThe deceleration of MS course observed throughout the years is determined not only by fewer RAW events, but also by a reduction in PIRA. However, the shift toward a mostly relapse‐independent progression highlights the importance of evaluating new therapies based on their effect on PIRA. ANN NEUROL 2025;97:95–103

AbstractEtherification and amination of aryl halide scaffolds are commonly used reactions in parallel medicinal chemistry to rapidly scan structure–activity relationships with abundant building blocks. Electrochemical methods for aryl etherification and amination demonstrate broad functional group tolerance and extended nucleophile scope compared to traditional methods. Nevertheless, there is a need for robust and scale‐transferable workflows for electrochemical compound library synthesis. Herein we describe a platform for automated electrochemical synthesis of C−X arylation (X=NH, OH) in flow to access compound libraries. A comprehensive Design of Experiment (DoE) study identifies an optimal protocol which generates high yields across>30 aryl halide scaffolds, diverse amines (including electron‐deficient sulfonamides, sulfoximines, amides, and anilines) and alcohols (including serine residues within peptides). Reaction sequences are automated on commercially available equipment to generate libraries of anilines and aryl ethers. The unprecedented application of potentiostatic alternating polarity in flow is essential to avoid accumulating electrode passivation. Moreover, it enables reactions to be performed in air, without supporting electrolyte and with high reproducibility over consecutive runs. Our method represents a powerful means to rapidly generate nucleophile independent C−X arylation compound libraries using flow electrochemistry.

Published: October 2024

AbstractSelective CO2 photoreduction into high‐energy‐density and high‐value‐added C2 products is an ideal strategy to achieve carbon neutrality and energy shortage, but it is still highly challenging due to the large energy barrier of the C−C coupling step and severe exciton annihilation in photocatalysts. Herein, strong and localized charge polarization is successfully induced on the surface of melon‐based organic semiconductors by creating dual active sites with a large charge asymmetry. Confirmed by multiscale characterization and theoretical simulations, such asymmetric charge distribution, originated from the oxygen dopants and nitrogen vacancies over melon‐based organic semiconductors, reduces exciton binding energy and boosts exciton dissociation. The as‐formed charge polarization sites not only donate electrons to CO2 molecules but also accelerate the coupling of asymmetric *CO*CO intermediates for CO2 photoreduction into ethanol by lowering the energy barrier of this process. Consequently, an exceptionally high selectivity of up to 97 % for C2H5OH and C2H5OH yield of 0.80 mmol g−1 h−1 have been achieved on this dual active sites organic semiconductor. This work, with its potential applicability to a variety of non‐metal multi‐site catalysts, represents a versatile strategy for the development of advanced catalysts tailored for CO2 photoreduction reactions.

Published: October 2024

AbstractZero‐dimensional (0D) structured lead‐free metal halides have recently attracted widespread attention due to their high photoluminescence quantum yield (PLQY) and negligible self‐absorption, showing enormous potential as optical waveguides towards miniaturized photonic devices. However, due to the great difficulty in growth of rod‐like nano/micro‐sized morphologies, such applications have been less explored. Herein, a new‐type emissive organic–inorganic manganese (II) halide crystal (TPS2MnCl4, TPS=C18H15S, triphenylsulfonium) in the form of microrods is synthesized via a facile chloride ion (Cl−) induced oriented growth method. Due to a combination of attractive features such as a high PLQY of 86 %, negligible self‐absorption and smooth crystal surface, TPS2MnCl4 microrods are well suited for use in optical waveguide with an ultra‐low optical loss coefficient of 1.20 ⋅ 10−4 dB μm−1, superior to that of most organic–inorganic metal halide hybrids, organic materials, polymers and metal nanoclusters to the best of our knowledge. Importantly, TPS2MnCl4 microrods can further work as dual‐mode optical waveguides, combining active and passive light transmission functionalities in one single crystal. In addition, TPS2MnCl4 microrods also display remarkable performance in lighting and anti‐counterfeiting due to their distinct optical properties and commendable stability.
