AbstractBACKGROUNDTo address water scarcity and promote sustainable resource management, more efficient and cost‐effective water treatment solutions are necessary. Particularly, pathogens in drinking water are a topic of growing concern. One promising technology is the use of photocatalytic nanoparticles activated by visible light as antibacterial agents. This study focuses on the characterization and antibacterial properties of Co–Zn ferrite nanocatalysts, tested against Escherichia coli.RESULTSThe CoxZn1−xFe2O4 (x = 0, 0.1, 0.4 and 0.6) ferrites were synthesized by the co‐precipitation method. Structural, morphological and optical analyses confirmed that these nanoparticles have a cubic spinel structure, with sizes of around 10 nm, and band gap energies suitable for visible light activation (1.4–1.7 eV). The antibacterial efficacy of the nanoparticles against E. coli was tested and compared with their photocatalytic performance employing phenol as organic pollutant model (highest phenol degradation for x = 0.6). Specifically, the antibacterial capacity of these nanoparticles was evaluated by comparing the ability of bacteria to grow after being incubated with the nanoparticles under visible light and in the dark. It was found that nanoparticles with lower cobalt content (x = 0 and 0.1) significantly reduced bacterial culturability under visible light. Transmission Electron Microscopy analysis revealed that nanoparticles with cobalt content caused bacteria to secrete biofilm, potentially offering some protection against the nanoparticles.CONCLUSIONZnFe2O4 nanoparticles show the highest antibacterial effect amongst those tested. This is attributed to the combined action of Zn2+ ion release and the photocatalytic effect under visible light. Furthermore, Zn might inhibit protective biofilm secretion, leading to higher antibacterial effects. © 2024 The Author(s).

AbstractBACKGROUNDThe increasing usage of tetracycline in antiviral therapy has caused severe aqueous water contamination, and advanced oxidation processes based on sulfate radicals have been recognized as an effective technique for degrading this antibiotic into harmless small molecules.RESULTSHerein, a strategy based on dopamine self‐polymerization was utilized to synthesize the magnetite/polydopamine‐ferric ion (Fe3O4/PDA‐Fe3+) catalyst with excellent magnetism and abundant surface functional groups. This catalyst exhibited high performance in activation of permonosulfate for tetracycline degradation. The surface properties and chemical composition of this catalyst were characterized by scanning electron microscopy, X‐ray diffraction, vibrating sample magnetometer, Fourier transform infrared and X‐ray photon spectroscopy, which indicated that Fe3O4/PDA‐Fe3+ could active permonosulfate to generate strong oxidizing free radicals for catalytic degradation of tetracycline. Beside its excellent catalytic activity, Fe3O4/PDA‐Fe3+ also exhibited superior structural stability and reusability, and this catalyst could be simply recycled from solution using an external magnet. Additional quenching experiments and chemical environment analysis confirmed that hydroxyl, sulfate and superoxide anion radicals, singlet oxygen and surface‐adsorbed oxygen contributed significantly to degradation of tetracycline.CONCLUSIONThis work proved that dopamine self‐polymerization strategy could be used as an effective route to produce highly active and structurally sturdy catalysts for the degradation of organic pollutant. © 2024 Society of Chemical Industry (SCI).

AbstractBACKGROUNDA novel silver adsorbent, (2Z,2′ E)‐2,2′‐((1,10‐phenanthroline‐2,9‐diyl)bis(methaneylylidene))bis(N‐phenylhydrazine‐1‐carboxamide) (PHMC), was synthesized for efficient Ag+ adsorption. PHMC was prepared by refluxing 1,10‐phenanthroline‐2,9‐dicarboxaldehyde with N‐phenylhydrazinecarboxamide at 120 °C. The structural and morphological properties of PHMC were characterized using various analytical techniques including FTIR, SEM, BET surface area analysis, 13CNMR, 1HNMR, and GC–MS, to confirm the formation of PHMC adsorbent.RESULTSThe results demonstrated that PHMC possesses an exceptional silver sorption capacity of 440.67 mg g−1 in aqueous solutions. Additionally, PHMC exhibited excellent reusability, with effective desorption of Ag(I) using a 1 M thiourea solution, enabling adsorbent regeneration. The adsorption of Ag+ onto PHMC was well described by Langmuir and D‐R isotherms, as well as pseudo‐second order and intraparticle diffusion (IPD) kinetic models. PHMC showed remarkable selectivity for silver, even in the presence of competing ions, and demonstrated significant stability, retaining over 95% of its initial capacity after four regeneration cycles and more than 80% after seven cycles. Thermodynamic investigations revealed that the sorption process was endothermic.CONCLUSIONPHMC proved to be a highly effective adsorbent for silver removal, with superior reusability compared to other materials. Optimal adsorption conditions were established for the removal of silver from liquid photographic waste. The recovered silver nitrate was successfully used to synthesize Ag nanoparticles using trisodium citrate (TSC) as a reducing agent, and the resulting nanoparticles were characterized using various analytical techniques to confirm the formation of silver nanoparticles. © 2024 Society of Chemical Industry (SCI).

ABSTRACTDOTA‐functionalized bisphosphonates can be useful tools for PET imaging of bone metastases when radiolabeled with 68Ga. Moreover, the versatility of DOTA allows the complexation of radiometals with therapeutic applications (e.g., 177Lu), positioning these bisphosphonates as attractive theranostic agents. Among these molecules, BPAMD is a compound whose radiolabeling with 68Ga has already been described, but only through manual methods. Thus, a fully automated protocol for 68Ga radiolabeling of BPAMD on the GAIA® ± LUNA® synthesis module was designed, and a thorough study of the radiolabeling conditions was undertaken. [68Ga]Ga‐BPAMD was produced in good radiochemical purity (> 93%) and high radiochemical yield (> 91%) using 0.3 M HEPES buffer. The nature of the reaction vessel showed no significant effect on the radiolabeling outcome. Similarly, addition of an antiradiolysis compound to the reaction medium did not significantly improve the already excellent stability of [68Ga]Ga‐BPAMD over time. The radiolabeled product obtained by automated synthesis was evaluated in vivo in healthy mice and confirmed high accumulation in the joints and along the backbone.

ABSTRACTThe variola virus, the causative agent of smallpox, has claimed more human lives than all other infectious diseases combined. Consequently, any epidemiological event involving related viruses (orthopoxviruses) triggers significant concern, as was the case with the pandemic rise of monkeypox virus (MPXV), the causative agent of monkeypox in 2022−2023. Smallpox vaccines, based on vaccinia virus antigens, are expected to provide cross‐protection against MPXV. Studying the general seroprevalence of orthopoxviruses in populations worldwide is crucial for estimating susceptibility, risks, and the need for vaccination campaigns. In this study, we aimed to evaluate the seroprevalence of antibodies capable of recognizing MPXV in a Brazilian population and assess the potential for cross‐protection from previous smallpox vaccinations. We analyzed demographic data, vaccination records, and serum levels of anti‐MPXV IgG measured by enzyme‐linked immunosorbent assay (ELISA) in 319 volunteers from Barreiras, Bahia, Brazil. Our main findings show that the numbers of volunteers with serum samples recognizing MPXV in ELISA, as well as their serum levels of anti‐MPXV IgG, did not differ significantly according to gender or address type. However, both male and female elderly volunteers exhibited significantly higher concentrations of anti‐MPXV IgG than adults, youth, and children. These results suggest that the elderly may benefit from a cross‐reactive immune response due to previous smallpox vaccinations, whereas adults, youth, and children appear susceptible to MPXV. Further investigations involving other populations are necessary to assess the necessity of vaccinating potentially vulnerable groups.

AbstractGuided growth for correction of rotational deformities has been reported in several preclinical and clinical studies. Different adverse effects, like growth retardation, articular deformities, and rebound effect have been reported. We have tested a novel plate concept (RotOs PlateTM) intended for the correction of rotational deformities of long bones by guided growth in a porcine model. The plate has sliding screw holes intended to allow for longitudinal growth. Fourteen skeletally immature female pigs were included in the study in a paired design. Mean duration of intervention was 88 days (83–98). CTscans and X‐rays were performed at plate insertion and removal. From the CTscans, 3D‐models of the left and right femora were made and used for measuring the achieved rotation. Three pigs were excluded for reasons not related to the plate design. The plates rotated as intended in all pigs. In two pigs, there was a cut‐out of the proximal screw on the lateral side. Data from these two pigs were included in the results. We observed a mean difference in rotation between the left and right femur of 5.7° in the external direction (CI: 3.7°−7.7°). No statistically significant deformities in the coronal and sagittal plane were observed. The plate worked as intended, that is, the intended rotation was achieved.Clinical SignificanceThis large animal study shows promising results for the feasibility of the method. It is an important first step in validating the technique and detecting possible adverse effects before clinical studies.

Published: November 2024

ABSTRACTThe global expansion of plastic‐mulched farmland, including China, raises concerns due to its rapid pace. Intensified tillage practices fulfill high food demand with limited farmland by increasing yields but harm the environment and health. Limited understanding exists regarding the underlying mechanisms of spatial diversity. This study uses spatial regression techniques to identify the multi‐scale patterns and driving forces. Nationally, fertility, frequent disasters, population density, and industrialized vegetable bases foster expansion, yet annual precipitation and urbanization‐related factors may impose constraints. Regionally, impacts are at times uncertain and contradicted. In agricultural optimization and development regions (AODRs), the distribution of plastic‐mulched farmland is especially relevant to soil fertility, household income, and planning factors, but is subject to land slope. Moderate development regions (MDRs) with unfavorable conditions witness plastic‐mulched farmland growth propelled by precipitation, temperature, and factors like E‐commerce, fixed assets, and road infrastructure. We have quantified these impacts through policy simulations, and identify that their extents can be largely different across regions. For example, adding one key vegetable county in the plan is assumed to increase the proportion of plastic‐mulched farmland by 0.229% in MDRs while only by 0.089% in AODRs. Crucially, adapting state‐led food localization initiatives is imperative.

AbstractBackgroundPET/CT and planning CT are commonly used medical images in radiotherapy for esophageal and nasopharyngeal cancer. However, repeated scans will expose patients to additional radiation doses and also introduce registration errors. This multimodal treatment approach is expected to be further improved.PurposeA new Transformer model is proposed to obtain pseudo‐PET/CT fusion images for esophageal and nasopharyngeal cancer radiotherapy.MethodsThe data of 129 cases of esophageal cancer and 141 cases of nasopharyngeal cancer were retrospectively selected for training, validation, and testing. PET and CT images are used as input. Based on the Transformer model with a “focus‐disperse” attention mechanism and multi‐consistency loss constraints, the feature information in two images is effectively captured. This ultimately results in the synthesis of pseudo‐PET/CT fusion images with enhanced tumor region imaging. During the testing phase, the accuracy of pseudo‐PET/CT fusion images was verified in anatomy and dosimetry, and two prospective cases were selected for further dose verification.ResultsIn terms of anatomical verification, the PET/CT fusion image obtained using the wavelet fusion algorithm was used as the ground truth image after correction by clinicians. The evaluation metrics, including peak signal‐to‐noise ratio, structural similarity index, mean absolute error, and normalized root mean square error, between the pseudo‐fused images obtained based on the proposed model and ground truth, are represented by means (standard deviation). They are 37.82 (1.57), 95.23 (2.60), 29.70 (2.49), and 9.48 (0.32), respectively. These numerical values outperform those of the state‐of‐the‐art deep learning comparative models. In terms of dosimetry validation, based on a 3%/2 mm gamma analysis, the average passing rates of global and tumor regions between the pseudo‐fused images (with a PET/CT weight ratio of 2:8) and the planning CT images are 97.2% and 95.5%, respectively. These numerical outcomes are superior to those of pseudo‐PET/CT fusion images with other weight ratios.ConclusionsThis pseudo‐PET/CT fusion images obtained based on the proposed model hold promise as a new modality in the radiotherapy for esophageal and nasopharyngeal cancer.

ABSTRACTAimTo investigate concurrent changes in short shift intervals (< 11 h) and workload among hospital employees.Design and Data SourcesThis cohort study of 1904 employees in one hospital district in Finland utilised data on employees' working hours for short shift intervals and workload based on the patient classifications aggregated to a 3‐week period level across 2 years, 2018–2019. The data was analysed by group‐based trajectory modelling and multinominal regression models.ResultsThe seven trajectories model had the best fit to the data—Group 1: very few short shift intervals that are decreasing and low workload (15.0%); Group 2: a low amount of short shift intervals that are decreasing and stable low workload (14.2%); Group 3: moderate amount of short shift intervals that are slightly increasing and low workload (25.1%); Group 4: a low amount of short shift intervals that are slightly decreasing and stable low workload that is slightly increasing (12.1%): Group 5: a moderate amount of both short shift intervals and workload (19.8%): Group 6: short shift intervals that are clearly decreasing, with higher than the average workload decreasing (5.6%); Group 7: moderate amount of short shift intervals and very high workload (8.3%).ConclusionsOnly a minority of hospital employees were found to have both high workloads and insufficient recovery possibilities, but the time‐related increases in objective workload were not compensated by better recovery possibilities in working hours. For shift scheduling, it is noteworthy that older employees might seek to work at units in which the workload is lower, which could be considered to support workability.Reporting MethodRecord.Patient or Public ContributionNo Patient or Public Contribution.
