Authors: Scheirton Linda , Mu Keli , Lohman Helene 
Published: September 2010

Abstract
OBJECTIVE. Errors occur in all health care professions. Practice errors, however, have not been systematically examined in occupational therapy. The purpose of this study was to examine occupational therapists’ responses to practice errors in physical rehabilitation settings.
METHOD. A qualitative focus group research method was used in this study and a total of 35 occupational therapists from four different states who had practice experience in physical rehabilitation settings participated in four focus groups. Focus group discussions were transcribed verbatim and analyzed by two investigators of the study. Qualitative software program, NUD*IST Vivo was used to aid the data analysis process.
RESULTS. Five major themes were generated from the data regarding practice errors, which included (1) Concept of practice error: It is against our standards; (2) Perceived causes of practice error: Not just an individual matter; (3) Emotional responses: I felt horrible; (4) Impact on practice: Doing things differently; and (5) Management of practice error: Being honest and taking initiative. Occupational therapists perceived practice error from a broad perspective and identified physical and psychosocial issues as practice error.
CONCLUSION. Most practice errors described by participants appeared to be preventable. Despite the tremendous emotional distress in reaction to making an error, participants valued the learning in the experience and made constructive practice changes. Findings of the study have implications for current educational training programs and practice such as the development of clinical reasoning related to patient safety and assertiveness training for hierarchical situations.

ImportanceProton beam therapy is an emerging radiotherapy treatment for patients with cancer that may produce similar outcomes as traditional photon-based therapy for many cancers while delivering lower amounts of toxic radiation to surrounding tissue. Geographic proximity to a proton facility is a critical component of ensuring equitable access both for indicated diagnoses and ongoing clinical trials.ObjectiveTo characterize the distribution of proton facilities in the US, quantify drive-time access for the population, and investigate the likelihood of long commutes for certain population subgroups.Design, Setting, and ParticipantsThis population-based cross-sectional study analyzed travel times to proton facilities in the US. Census tract variables in the contiguous US were measured between January 1, 2017, and December 31, 2021. Statistical analysis was performed from September to November 2023.ExposuresDrive time in minutes to nearest proton facility. Population totals and prevalence of specific factors measured from the American Community Survey: age; race and ethnicity; insurance, disability, and income status; vehicle availability; broadband access; and urbanicity.Main Outcomes and MeasuresPoor access to proton facilities was defined as having a drive-time commute of at least 4 hours to the nearest location. Median drive time and percentage of population with poor access were calculated for the entire population and by population subgroups. Univariable and multivariable odds of poor access were also calculated for certain population subgroups.ResultsGeographic access was considered for 327 536 032 residents of the contiguous US (60 594 624 [18.5%] Hispanic, 17 974 186 [5.5%] non-Hispanic Asian, 40 146 994 [12.3%] non-Hispanic Black, and 195 265 639 [59.6%] non-Hispanic White; 282 031 819 [86.1%] resided in urban counties). The median (IQR) drive time to the nearest proton facility was 96.1 (39.6-195.3) minutes; 119.8 million US residents (36.6%) lived within a 1-hour drive of the nearest proton facility, and 53.6 million (16.4%) required a commute of at least 4 hours. Persons identifying as non-Hispanic White had the longest median (IQR) commute time at 109.8 (48.0-197.6) minutes. Multivariable analysis identified rurality (odds ratio [OR], 2.45 [95% CI, 2.27-2.64]), age 65 years or older (OR, 1.09 [95% CI, 1.06-1.11]), and living below the federal poverty line (OR, 1.22 [1.20-1.25]) as factors associated with commute times of at least 4 hours.Conclusions and RelevanceThis cross-sectional study of drive-time access to proton beam therapy found that disparities in access existed among certain populations in the US. These results suggest that such disparities present a barrier to an emerging technology in cancer treatment and inhibit equitable access to ongoing clinical trials.

AbstractNatural polymers, particularly plant‐derived nanocelluloses, self‐organize into hierarchical structures, enabling mechanical robustness, bright iridescence, emission, and polarized light reflection. These biophotonic properties are facilitated by the assembly of individual components during evaporation, such as cellulose nanocrystals (CNCs), which exhibit a left‐handed helical pitch in a chiral nematic state. This work demonstrates how optically active films with pre‐programmed opposite handedness (left or right) can be constructed via shear‐induced twisted printing with clockwise and counter‐clockwise shearing vectors. The resulting large‐area thin films are transparent yet exhibit pre‐determined mirror‐symmetrical optical activity, enabling the distinction of absorbed and emitted circularly polarized light. This processing method allows for sequential printing of thin and ultrathin films with twisted layered organization and on‐demand helicity. The complex light polarization behavior is due to step‐like changes in linear birefringence within each deposited layer and circular birefringence, different from that of conventional CNC films as revealed with Muller matrix analysis. Furthermore, intercalating an achiral organic dye into printed structures induces circularly polarized luminescence while preserving high transmittance and controlled handedness. These results suggest that twisted sequential printing can facilitate the construction of chiroptical metamaterials with tunable circular polarization, absorption, and emission for optical filters, encryption, photonic coatings, and chiral sensors.

Published: May 2024

AbstractPlatinum is the most widespread electrode material used for implantable biomedical and neuroelectronic devices, motivating exploring ways to improve its performance and understand its fundamental properties. Using reactive magnetron sputtering, PtOx is prepared, which upon partial reduction yields a porous thin‐film form of platinum with favorable properties, notably record‐low impedance values outcompeting other reports for platinum‐based electrodes. It is established that its high electrochemical capacitance scales with thickness, in the way of volumetric capacitor materials like IrOx and poly(3,4‐ethylenedioxythiophene), PEDOT. Unlike these two well‐known analogs, however, it is found that PtOx capacitance is not caused by reversible pseudofaradaic reactions but rather due to high surface area. In contrast to IrOx, PtOx is not a reversible valence‐change oxide, but rather a porous form of platinum. The findings show that this oxygen‐containing form of Pt can place Pt electrodes on a level competitive with IrOx and PEDOT. Due to its relatively low cost and ease of preparation, PtOx can be a good choice for microfabricated bioelectronic devices.

AbstractAchieving bacterial killing and osteogenic formation on an implant surface rarely occurs. In this study, a novel surface design–a palladium hydride (PdHx) film that enables these two distinct features to coexist is introduced. The PdHx lattice captures protons in the extracellular microenvironment of bacteria, disrupting their normal metabolic activities, such as ATP synthesis, nutrient co‐transport, and oxidative stress. This disruption leads to significant bacterial death, as evidenced by RNA sequence analysis. Additionally, the unique enzymatic activity and hydrogen‐loading properties of PdHx activate the human antioxidant system, resulting in the rapid clearance of reactive oxygen species. This process reshapes the osteogenic immune microenvironment, promoting accelerated osteogenesis. These findings reveal that the downregulation of the NOD‐like receptor signaling pathway is critical for activating immune cells toward M2 phenotype polarization. This novel surface design provides new strategies for modifying implant coatings to simultaneously prevent bacterial infection, reduce inflammation, and enhance tissue regeneration, making it a noteworthy contribution to the field of advanced materials.

AbstractThis study synthesizes silicon (Si) powders with lithium silicates including lithium orthosilicate (Li4SiO4), lithium metasilicate (Li2SiO3), and lithium disilicate (Li2Si2O5), creating a composite structure of crystalline Si within a LixSiyOz matrix through the lithiothermic reduction reaction (LTRR) process. The reduction of Li‐ion consumption of the anode is investigated by 1) initial solid electrolyte interphase (SEI) layer formation, 2) SEI layer formation in response to Si expansion‐induced damage, 3) trapping of Li ions at Si defects, and 4) side reactions during initial charge and discharge cycles. Si/LixSiyOz electrode exhibits a specific capacity of 1522.2 mAh g−1 and an initial coulombic efficiency of 83.5%. The effect of the calendering process is observed, and a pressurization condition of 5000 kgf cm−2 or less is set, and the ICE is improved to 93.4%–96%. Si/LixSiyOz electrodes outperform pure crystalline Si electrodes in specific capacity (7.3%), ICE (42%), and retention characteristics (17%). The integration of the LixSiyOz matrix into Si anodes enhances Li‐ion transport and partially suppresses Si expansion. Additionally, the Si/LixSiyOz electrode exhibits superior rate capability in the 0.2–1.6 A g−1 range.

AbstractThe recent era of research has been focused on attaining precise and adjustable propulsion modes in micromotors, with remarkable implications in microrobotics and active‐matter applications. This study introduces a novel design of rod‐shaped micromotors featuring light‐driven motion and wavelength‐dependent multimodal swimming behavior. The micromotors are fabricated through the Glancing Angle Deposition (GLAD) technique, which offers a flexible approach to engineering surfaces by incorporating photocatalytic materials (TiO2 and Cu2O) at specific locations. Here, three distinct designs of micromotors (titania, hybrid‐1, and hybrid‐2) are presented that are programmed to showcase diverse behaviors of movements (linear, helical, and axial rotation) when exposed to a specific wavelength. The application of light facilitates convenient control over activity and mode switching by altering between UV and visible ranges. Numerical modeling using a finite element approach is performed to validate the experimental results, demonstrating excellent agreement with the experimental findings. The present study is anticipated to be helpful in tailoring such complex micro/nanoscale advanced functional materials with intricating swimming modes desired for various applications in micro/nanorobotics.

Published: May 2024

AbstractIn this study, the NiMo6Se8 Chevrel phase is analyzed using Density Functional Theory (DFT) and the Vienna Ab‐initio Simulation Package (VASP). The analysis focuses on the phase's structural, electrical, and mechanical characteristics to fill gaps in the current literature. The presence of a rhombohedral crystal structure confirms its thermodynamic stability, as indicated by a negative formation enthalpy, which suggests that it can be synthesized under favorable conditions. The electronic properties of the phase are analyzed, indicating that it exhibits semiconductor characteristics with a bandgap of 1.07 eV. This makes it appropriate for various technological applications. The estimated elastic constants provide an indication of mechanical strength and flexibility, with a noticeable presence of anisotropic elasticity. The confirmation of dynamical stability is achieved by analyzing the phonon dispersion curve, which reveals the absence of any negative frequencies. Furthermore, the material has a low thermal conductivity, increasing its suitability for thermoelectric applications. The analysis emphasizes the versatile capabilities of the NiMo6Se8 Chevrel phase, especially in thermoelectric and energy storage applications, showcasing its promising potential for future technological implementation.

Published: May 2024

AbstractMagnetic skyrmions, despite being promising ultra‐low energy information carriers with wide bandwidth and nonvolatility, are not used for any universal scalable logic system. Here, a detailed understanding of skyrmion motion in nanowires under different geometries and drive conditions is established. Then, these insights are used to introduce a general Boolean‐universal gate block system with components, emulation, and simulation algorithms. The resulting system can collectively form a scalable, cascadable, and universal skyrmion logic system and produce arbitrary logic designs. The NOR, AND, OR, NAND, XNOR, and FULL ADDER gates are provided here as example demonstrations of the system. The toolkit lays the foundation for bridging the gap between theoretical exploration and practical implementation of skyrmion‐based computing. The skyrmion block components may help reduce energy consumption per logic operation after eliminating Joule heating. The insights and designs may help skyrmions be used in state‐of‐the‐art electronic design automation.

AbstractRechargeable Li‐CO2 batteries are considered as a promising carbon‐neutral energy storage technology owing to their ultra‐high energy density and efficient CO2 capture capability. However, the sluggish CO2 reduction/evolution kinetics impedes their practical application, which leads to huge overpotentials and poor cyclability. Multi‐element transit metal oxides (TMOs) are demonstrated as effective cathodic catalysts for Li‐CO2 batteries. But there are no reports on the integration of defect engineering on multi‐element TMOs. Herein, the oxygen vacancy‐bearing Li‐Ni‐Co‐Mn multi‐oxide (Re‐NCM‐H3) catalyst with the α‐NaFeO2‐type structure is first fabricated by annealing the NiCoMn precursor that derived from spent ternary LiNi0.8Co0.1Mn0.1O2 cathode, in H2 at 300 °C. As demonstrated by experimental results and theory calculations, the introduction of moderate oxygen vacancy has optimized electronic state near the Fermi level (Ef), eventually improving CO2 adsorption and charge transfer. Therefore, the Li‐CO2 batteries with Re‐NCM‐H3 catalyst deliver a high capacity (11808.9 mAh g−1), a lower overpotential (1.54 V), as well as excellent stability over 216 cycles at 100 mA g−1 and 165 cycles at 400 mA g−1. This study not only opens up a sustainable application of spent ternary cathode, but also validates the potential of multi‐element TMO catalysts with oxygen defects for high‐efficiency Li‐CO2 batteries.

Published: May 2024

AbstractFerroptosis plays important roles both in normal physiology and multiple human diseases. It is well known that selenoprotein named glutathione peroxidase 4 (GPX4) is a crucial regulator for ferroptosis. However, it remains unknown whether other selenoproteins responsible for the regulation of ferroptosis, particularly in gut diseases. In this study, it is observed that Selenoprotein I (Selenoi) prevents ferroptosis by maintaining ether lipids homeostasis. Specific deletion of Selenoi in intestinal epithelial cells induced the occurrence of ferroptosis, leading to impaired intestinal regeneration and compromised colonic tumor growth. Mechanistically, Selenoi deficiency causes a remarkable decrease in ether‐linked phosphatidylethanolamine (ePE) and a marked increase in ether‐linked phosphatidylcholine (ePC). The imbalance of ePE and ePC results in the upregulation of phospholipase A2, group IIA (Pla2g2a) and group V (Pla2g5), as well as arachidonate‐15‐lipoxygenase (Alox15), which give rise to excessive lipid peroxidation. Knockdown of PLA2G2A, PLA2G5, or ALOX15 can reverse the ferroptosis phenotypes, suggesting that they are downstream effectors of SELENOI. Strikingly, GPX4 overexpression cannot rescue the ferroptosis phenotypes of SELENOI‐knockdown cells, while SELENOI overexpression can partially rescue GPX4‐knockdown‐induced ferroptosis. It suggests that SELENOI prevents ferroptosis independent of GPX4. Taken together, these findings strongly support the notion that SELENOI functions as a novel suppressor of ferroptosis during colitis and colon tumorigenesis.

AbstractEfficient semi‐transparent solar cells can extend the adoption of photovoltaics beyond standard utility‐scale, commercial, or residential applications. Halide perovskites are particularly suitable in this respect owing to their tunable bandgap. The main drawbacks in the development of transparent perovskite solar cells are the high open‐circuit voltage (Voc) deficit and the difficulties in depositing high‐quality thin films over large area substrates, given the low solubility of bromide and chloride precursors. In this work, passivation strategies are developed for the high bandgap Br perovskite able to reduce charge recombination and consequently improve the Voc. The study demonstrates 1 cm2 perovskite solar cells with Voc up to 1.73 V (1.83 eV Quasi Fermi Level Splitting) and a PCE of 8.1%. The average visible transmittance (AVT) exceeds 70% by means of a bifacial light management and a record light utilization efficiency (LUE) of 5.72 is achieved. Moreover, the potential use of the technology is evaluated toward Internet of Things (IoT) application owing to a bifaciality factor of 87% along with 17% PCE under indoor lighting. Finally, the up‐scaling is demonstrated by fabricating 20 cm2 active area modules with PCE of 7.3% and Voc per cell up to 1.65 V.
Weighing the gold standard: The breadth of emergency medicine core content covered by textbooks
Authors: Preiksaitis Carl , Nawaz Amana , Ousta Alaa , Mackey Cassandra 
Published: May 2024

AbstractBackgroundTextbooks are often considered the criterion standard in medical education, but there is a growing preference for free open‐access medical education (FOAM) content among learners. Despite FOAM's appeal, these resources often fall short in covering core content as comprehensively as the American Board of Emergency Medicine's 2019 Model of the Clinical Practice of Emergency Medicine (MCPEM), thereby sustaining the recommendation for textbook use. However, textbooks have limitations, such as how quickly content can become outdated. Notably, there is no evaluation of the comprehensiveness of emergency medicine (EM) textbooks in the literature.MethodsThis observational cross‐sectional study compared Rosen's Emergency Medicine: Concepts and Clinical Practice 10th Edition (Rosen's) and Tintinalli's Emergency Medicine: A Comprehensive Study Guide 9th Edition (Tintinalli's) with the MCPEM subtopics. Each textbook chapter was reviewed for content alignment with MCPEM subtopics. The primary outcome was the proportion of MCPEM subtopics covered by each textbook. Secondary outcomes included the count of chapters covering each topic and their distribution relative to the core content weighting in the ABEM National Qualifying Examination (NQE).ResultsRosen's covered 95.3% of MCPEM subtopics (837 unique subtopics), and Tintinalli's covered 94.5% (826 unique subtopics). Both textbooks overrepresented topics like toxicology and psychobehavioral disorders compared to their weighting in the NQE. Relatively underrepresented topics included environmental disorders, cardiovascular disorders, renal and urogenital disorders, and traumatic disorders in Rosen's and other core competencies and cardiovascular disorders in Tintinalli's. The textbooks varied significantly in coverage of certain topics.ConclusionsBoth Rosen's and Tintinalli's comprehensively cover MCPEM subtopics, with some discrepancies in topic representation compared to the NQE. While textbooks offer depth and breadth, they may not fully align with the NQE content distribution. A diversified approach to EM education, combining traditional textbooks and FOAM resources may be required for comprehensive learning.
