ImportanceIdentifying disparities in health outcomes related to modifiable patient factors can improve patient care.ObjectiveTo compare likelihood of withdrawal of life-supporting treatment (WLST) and mortality in patients with complete cervical spinal cord injury (SCI) with different types of insurance.Design, Setting, and ParticipantsThis retrospective cohort study collected data between 2013 and 2020 from 498 trauma centers participating in the Trauma Quality Improvement Program. Participants included adult patients (older than 16 years) with complete cervical SCI. Data were analyzed from November 1, 2023, through May 18, 2024.ExposureUninsured or public insurance compared with private insurance.Main Outcomes and MeasuresCoprimary outcomes were WLST and mortality. The adjusted odds ratio (aOR) of each outcome was estimated using hierarchical logistic regression. Propensity score matching was used as an alternative analysis to compare public and privately insured patients. Process of care outcomes, including the occurrence of a hospital complication and length of stay, were compared between matched patients.ResultsThe study included 8421 patients with complete cervical SCI treated across 498 trauma centers (mean [SD] age, 49.1 [20.2] years; 6742 male [80.1%]). Among the 3524 patients with private insurance, 503 had WLST (14.3%) and 756 died (21.5%). Among the 3957 patients with public insurance, 906 had WLST (22.2%) and 1209 died (30.6%). Among the 940 uninsured patients, 156 had WLST (16.6%) and 318 died (33.8%). A significant difference was found between uninsured and privately insured patients in the adjusted odds of WLST (aOR, 1.49; 95% CI, 1.11-2.01) and mortality (aOR, 1.98; 95% CI, 1.50-2.60). Similar results were found in subgroup analyses. Matched public compared with private insurance patients were found to have significantly greater odds of hospital complications (odds ratio, 1.27; 95% CI, 1.14-1.42) and longer hospital stay (mean difference 5.90 days; 95% CI, 4.64-7.20), which was redemonstrated on subgroup analyses.Conclusions and RelevanceHealth insurance type was associated with significant differences in the odds of WLST, mortality, hospital complications, and days in hospital among patients with complete cervical SCI in this study. Future work is needed to incorporate patient perspectives and identify strategies to close the quality gap for the large number of patients without private insurance.
Brief report: Social comparison, hypercompetitiveness, and indirect aggression: Associations with loneliness and mental health

Published: August 2024

AbstractIndirect aggression is commonly used in adulthood, but most researchers have focused on this behavior in romantic relationships or from an intrasexual competition perspective. Therefore, we aimed to understand the social characteristics and mental health correlates of indirect aggression by combining perspectives from developmental psychopathology and evolutionary psychology. We examined: (1) whether social characteristics (social comparison, hypercompetitiveness) contributed to indirect aggression (perpetration, victimization) and (2) whether there were indirect effects from indirect aggression (perpetration, victimization) to mental health difficulties through loneliness. In a cross‐sectional sample of 475 young adults (57.7% women, 51.6% White, Mage = 20.2, SDage = 2.18), path analyses revealed that social comparison predicted indirect aggression victimization, which indirectly predicted mental health difficulties (depression, anxiety, somatic symptoms) through loneliness. In contrast, indirect aggression perpetration was only predicted by hypercompetitiveness. The findings highlight that reframing cognitions associated with social comparison could help prevent indirect aggression and mental health difficulties among young people.

AbstractPhotomechanical crystals have applications in light‐fueled actuators and soft robots. Herein, light‐responsive, versatile, anthraquinone dye crystal oscillators actuated via natural vibrations that are resonated by a photothermal effect are described. A black needle‐shaped crystal cantilever oscillates at 70 Hz in the first mode of natural vibration upon irradiation by broad‐wavelength light ranging from the ultraviolet through the visible to the near‐infrared, and also under continuous‐wavelength light (400–2000 nm). The second and third natural vibration modes are induced at higher frequencies (530 and 1350 Hz) and evidence complex flagellum‐like motions. The frequency can be readily tuned by moving the support of a crystal piece; this is analogous to playing a guitar. The crystal exhibits high durability (more than 10 000 cycles): the high elasticity prevents deterioration. Oscillatory motions can be designed via simulations using finite element analysis. This work will facilitate the use of photomechanical crystals in light‐fueled soft robots.

AbstractMicrowave (MW) therapy is an emerging therapy with high efficiency and deep penetration to combat the crisis of bacterial resistance. However, as the energy of MW is too low to induce electron transition, the mechanism of MW catalytic effect remains ambiguous. Herein, a cerium‐based metal–organic framework (MOF) is fabricated and used in MW therapy. The MW‐catalytic performance of CeTCPP is largely dependent on the ions in the liquid environment, and the electron transition is achieved through a “tribovoltaic effect” between water molecules and CeTCPP. By this way, CeTCPP can generate reactive oxygen species (ROS) in saline under pulsed MW irradiation, showing 99.9995 ± 0.0002% antibacterial ratio against Staphylococcus aureus (S. aureus) upon two cycles of MW irradiation. Bacterial metabolomics further demonstrates that the diffusion of ROS into bacteria led to the bacterial metabolic disorders. The bacteria are finally killed due to “amino acid starvation”. In order to improve the applicability of CeTCPP, It is incorporated into alginate‐based hydrogel, which maintains good MW catalytic antibacterial efficiency and also good biocompatibility. Therefore, this work provides a comprehensive instruction of using CeTCPP in MW therapy, from mechanism to application. This work also provides new perspectives for the design of antibacterial composite hydrogel.

Published: August 2024

AbstractDrug‐resistant pathogens significantly threaten human health and life. Simply killing drug‐resistant pathogens cannot effectively eliminate their threat since the drug‐resistant genes (DRGs) released from dead drug‐resistant pathogens are difficult to eliminate and can further spread via horizontal gene transfer, leading to the spread of drug resistance. The development of antibacterial materials with sterilization and DRGs cleavage activities is highly crucial. Herein, a living system, Ce‐PEA@Bdello, is fabricated with bacterial killing and DRGs cleavage activities for blocking bacterial drug resistance dissemination by engineered Bdellovibrio bacteriovorus (Bdello). Ce‐PEA@Bdello is obtained by engineering Bdello with dopamine and a multinuclear cerium (IV) complex. Ce‐PEA@Bdello can penetrate and eliminate kanamycin‐resistant P. aeruginosa (KanR) biofilms via the synergistic effect of predatory Bdello and photothermal polydopamine under near‐infrared light. Additionally, the DNase‐mimicking ability of Ce‐PEA@Bdello endows it with genome and plasmid DNA cleavage ability. An in vivo study reveals that Ce‐PEA@Bdello can eliminate P. aeruginosa (KanR) and cleave DRGs in scald/burn infected wounds to block the spread of drug resistance and accelerate wound healing. This bioactive system constructed from natural living materials offers a promising means for blocking the spread of drug resistance.

AbstractSince wearable technologies for telemedicine have emerged to tackle global health concerns, the demand for well‐attested wearable healthcare devices with high user comfort also arises. Skin‐wearables for health monitoring require mechanical flexibility and stretchability for not only high compatibility with the skin's dynamic nature but also a robust collection of fine health signals from within. Stretchable electrical interconnects, which determine the device's overall integrity, are one of the fundamental units being understated in wearable bioelectronics. In this review, a broad class of materials and engineering methodologies recently researched and developed are presented, and their respective attributes, limitations, and opportunities in designing stretchable interconnects for wearable bioelectronics are offered. Specifically, the electrical and mechanical characteristics of various materials (metals, polymers, carbons, and their composites) are highlighted, along with their compatibility with diverse geometric configurations. Detailed insights into fabrication techniques that are compatible with soft substrates are also provided. Importantly, successful examples of establishing reliable interfacial connections between soft and rigid elements using novel interconnects are reviewed. Lastly, some perspectives and prospects of remaining research challenges and potential pathways for practical utilization of interconnects in wearables are laid out.

AbstractIdeal temperature condition is one of the essential determinants that critically impact the quality of food products. Conventional water‐based ice cubes present challenges from meltwater being breeding grounds for microorganisms and heightening the risk for cross‐contamination. Hereby, the presented cellulose‐based hydrogels crosslinked by epichlorohydrin are dip‐coated with alginate/calcium chloride to form a core–shell structure for achieving the critical benchmarks of an ideal food coolant with limited meltwater production, high‐water retention capacity, and high mechanical strength. The structures and properties of the hydrogels before and after freeze–thaw cycles are characterized by scanning electron microscopy, compressive test, water retention test, and differential scanning calorimetry. All formulated hydrogels demonstrate promising compressive strength, latent heat of fusion, and water retention properties. Notably, the C2A10Cl hydrogel exhibits a maximum compressive strength of 144.7 kPa and high latent heat of fusion of 272.5 J g–1, which is better than previously reported sustainable hydrogel coolants. Furthermore, comparison studies reveal that the cellulose‐based hydrogels demonstrate a similar thawing pattern to conventional ice cubes but without the generation of any meltwater. The temperature of blueberries can be cooled down from 22 to 3.9 °C in 32 min by the hydrogels and in 26 min by ice cubes, respectively.

Published: August 2024

AbstractThis study examines producer participation choices considering a variety of potential benefits linked to state‐sponsored marketing programs, using a real choice dataset of farmers in Missouri. Multinomial logit models are employed to predict determinants of farmer enrollment in three tiers of the Missouri Grown local food marketing program: free, $50, and $100 memberships. We find that farmers who expect to increase sales or receive special services from the program are more likely to choose paid membership levels, while those who seek new opportunities are more associated with free participation. Furthermore, farms with annual sales above $150,000 and those with male or white decision‐makers are more likely to be $100 members, while young and beginning farmers tend to participate at a paid tier of $50 in the program.

AbstractCovalent organic frameworks (COFs) offer remarkable versatility, combining ordered structures, high porosity, and tailorable functionalities in nanoscale reaction spaces. Herein, we report the synthesis of a series of isostructural, photoactive Wurster‐type COFs achieved by manipulating the chemical and electronic nature of the Wurster aromatic amine building blocks. A series of donor‐acceptor‐donor (D‐A‐D) Wurster building block molecules was synthesized by incorporating heteroaromatic acceptors with varying strengths between triphenylamine donor groups. These tailored building blocks were integrated into a 2D COF scaffold, resulting in highly crystalline structures and similar morphologies across all COFs. Remarkably, this structural uniformity was also achieved in the synthesis of homogeneous and oriented thin films. Steady‐state photoluminescence revealed a tunable red‐shift in film emission exceeding 100 nm, demonstrating effective manipulation of their optical properties. Furthermore, photoelectrochemical (PEC) water splitting studies exhibited a doubled current density (8.1 μA cm−2 at 0.2 VRHE) for the COF with the strongest acceptor unit. These findings highlight the potential of Wurster D‐A‐D COFs in photoelectrochemical water splitting devices and pave the way for further exploration of chemical functionality‐reactivity‐property relationships in this promising class of photoactive materials.

AbstractOrganic‐inorganic halide perovskite (OIHP) single crystals are promising for optoelectronic application, but their high surface trap density and associated ion migration hinders device performance and stability. Herein, a one‐dimensional (1D) perovskites are designed and proposed as blocking layer at the crystal/electrode interface to mitigate the surface issues. As a model system, the interface ion migration in Cs0.05FA0.95PbI3 (FA=formamidinium) single‐crystal perovskite solar cells (PSCs) is obviously suppressed, leading to increase of T90 lifetime from 260 to 1000 hours, five times better than previously reported results. Besides, the reduction of surface iodide ion vacancies inhibits nonradiative recombination, thus increasing the efficiency from 22.1 % to 23.8 %, which is one of the highest values for single‐crystal PSCs. Since the deficient crystal surface is a universal and open issue, our strategy is instructive for optimizing diverse single‐crystal perovskite devices.

Abstract7‐Azaindole has been integrated as building block with complementary N−H⋅⋅⋅N hydrogen bonding sites for the synthesis of a tetrahedral molecular tecton, namely tetra(α‐carbolin‐6‐yl)methane, TACM. The self‐assembly of this molecule results in a 3D hydrogen‐bonded organic framework (HOF). This supramolecular structure constitutes a crystalline microporous material with an extraordinary thermal and chemical robustness. Single crystal X‐ray diffraction reveals how the five‐fold catenation of diamonoid systems, stabilized by hydrogen bonds and π–π interactions, form an interpenetrated network with monodimensional channels. The structural features of the crystalline material are also observed by transmission electron microscopy (TEM). Additionally, the microporosity of the activated TACM‐HOF is characterized by gas sorption (N2, CO2, CH4 and H2) experiments performed at different pressures. A selective adsorption is observed for CO2 uptake and TACM‐HOF also presents a good adsorption capacity for H2 among supramolecular organic frameworks.

AbstractOver the past decade, polymer thermoelectric materials featuring flexibility, lightness, and bio‐friendliness have been paid increasing attention as promising candidates for waste heat recovery and energy generation. For a long time, the dominant approach to optimizing the thermoelectric performance of most organic materials is chemical doping, which, however, is not always ideal for practical applications due to its tendency to involve intricate processing procedure and trigger material and device instability. Currently, the pursuit of single‐component neutral thermoelectric materials without exogenous doping presents a compelling alternative. In this work, we designed and synthesized a high‐spin polymer material, PBBT‐TT, by simultaneously employing thieno[3,4‐b]thiophene (TbT) and benzo[1,2‐c : 4,5‐c′]bis[1,2,5]thiadiazole (BBT) units with pronounced proquinoidal characteristics, its analogue, PBBT‐T to demonstrate the effect of the TbT unit was also synthesized. The results indicate that because of the enhanced quinoidal resonance, increased spin density and strong intermolecular antiferromagnetic coupling, PBBT‐TT exhibits high intrinsic electrical conductivity and Seebeck coefficient, which showcases an outstanding power factor of 26.1 μW m−1 K−2 without doping. This achievement surpasses other neutral organic conjugated polymer and radical conductors, and is even comparable to some typical early‐stage doped polymers. Notably, PBBT‐TT exhibits remarkable ambient stability, retaining its initial thermoelectric performance over a 120‐day period. Our finding demonstrates that modulating the intermolecular spin interactions in open‐shell polymers through the introduction of strong proquinoidal units is an effective strategy for the development of doping‐free, intrinsically high‐performance polymer thermoelectric materials.

AbstractOrganic photothermal conversion materials hold immense promise for various applications owing to their structural flexibility. Recent research has focused on enhancing near‐infrared (NIR) absorption and mitigating radiative transition processes. In this study, we have developed a viable approach to the design of photothermal conversion materials through the construction of ternary organic cocrystals, by introducing a third component as a molecular blocker and motion unit into a binary donor–acceptor system. Superstructural and photophysical properties of the ternary cocrystals were characterized using various spectroscopic techniques. The role of the molecular blocker in radical stabilization and photothermal conversion was demonstrated. Intriguingly, the motions of the entire pyrene molecules in the cocrystal have been observed by the results of variable temperature single‐crystal X‐ray diffraction. The excellent performance of the ternary cocrystal as a photothermal material was validated through efficient NIR‐II photothermal and solar‐driven water evaporation experiments. The efficiency of water evaporation reached 88.7 %, with a corresponding evaporation rate of 1.29 kg m−2 h−1, representing excellent performance among pure organic small molecular photothermal conversion materials. Our research underscores the introduction of molecular blockers and motion units to stabilize radicals and produce outstanding photothermal conversion materials, offering new pathways for developing efficient and stable photothermal conversion materials.

Published: August 2024

AbstractExploring high‐performance anion exchange membranes (AEM) for water electrolyzers (AEMWEs) is significant for green hydrogen production. However, the current AEMWEs are restricted by the poor mechanical strength and low OH− conductivity of AEMs, leading to the low working stability and low current density. Here, we develop a robust AEM with polybiphenylpiperidium network by combining the crosslinking with triazine and the capping with pyridine for advanced AEMWEs. The AEM exhibits an excellent mechanical strength (79.4 MPa), low swelling ratio (19.2 %), persistent alkali stability (≈5,000 hours) and high OH− conductivity (247.2 mS cm−1) which achieves the state‐of‐the‐art AEMs. Importantly, when applied in AEMWEs, the corresponding electrolyzer equipped with commercial nickel iron and nickel molybdenum catalysts obtained a current density of up to 3.0 A cm−2 at 2 V and could be stably operated ~430 h at a high current density of 1.6 A cm−2, which exceeds the most of AEMWEs. Our results suggest that triazine crosslinking and pyridine capping can effectively improve the overall performance of the AEMWEs.
