AbstractPurposeWhether the longevity of total knee arthroplasty (TKA) differs between postoperative phenotypes has not been investigated. This study aims to examine which phenotype has a worse long‐term survival rate than the reference phenotype (neutral alignment‐parallel joint line), and whether joint‐line obliquity (JLO) affects the survivorship of TKA.MethodsA total of 945 knees that underwent primary TKAs for primary osteoarthritis from January 2000 to January 2009 were included. These were classified into nine postoperative phenotypes based on the combined assessment of the hip–knee–ankle (HKA) angle and JLO, measured on standing radiographs. The 5‐, 10‐ and 15‐year survival rates were analysed using Kaplan–Meier methods and log‐rank tests. The long‐term survival rates of each phenotype were compared with the reference phenotype.ResultsThere were 55 aseptic mechanical failures within a period of 10.4 ± 5.0 years. The most frequently observed phenotypes were the reference phenotype (n = 527), neutral alignment‐lateral joint‐line inclination (n = 162), varus alignment‐lateral joint‐line inclination (n = 104) and varus alignment‐parallel joint line (n = 101). The overall failure rate for each phenotype was 3.6%, 3.7%, 18.3% and 7.9%, respectively. Only the 10‐ and 15‐year survival rates of the varus alignment‐lateral joint‐line inclination phenotype were significantly different from those of the reference phenotype (97%–93% vs. 90%–69%; p = 0.017, <0.001).ConclusionThe lateral joint‐line inclination phenotype had an inferior long‐term survival rate after varus‐aligned TKA. This suggested that alignment and JLO affected the long‐term survival rate of patients who underwent TKA.Level of EvidenceLevel III, retrospective cohort study.

ABSTRACTObjectivesUnder optimal conditions, afferent and efferent human skin graft microcirculation can be restored 8–12 days postgrafting. Still, the evidence about the reperfusion dynamics beyond this period in a dermato‐oncologic setting is scant. We aimed to characterise the reperfusion of human skin grafts over 4 weeks according to the necrosis extension (less than 20%, or 20%–50%) and anatomic location using laser speckle contrast imaging (LSCI).MethodsOver 16 months, all eligible adults undergoing skin grafts following skin cancer removal on the scalp, face and lower limb were enroled. Perfusion was assessed with LSCI on the wound margin (control skin) on day 0 and on the graft surface on days 7, 14, 21 and 28. Graft necrosis extension was determined on day 28.ResultsForty‐seven grafts of 47 participants were analysed. Regardless of necrosis extension, graft perfusion equalled the control skin by day 7, surpassed it by day 21, and stabilised onwards. Grafts with less than 20% necrosis on the scalp and lower limb shared this reperfusion pattern and had a consistently better‐perfused centre than the periphery for the first 21 days. On the face, the graft perfusion did not differ from the control skin from day 7 onwards, and there were no differences in reperfusion within the graft during the study.ConclusionSkin graft reperfusion is a protracted process that evolves differently in the graft centre and periphery, influenced by postoperative time and anatomic location. A better knowledge of this process can potentially enhance the development of strategies to induce vessel ingrowth into tissue‐engineered skin substitutes.

AbstractAimTo explore the experiences of health visits within the school health services from the perspective of adolescents with migration experiences.DesignA descriptive qualitative study.MethodsData were collected using focus groups and semi‐structured individual interviews with adolescents with migration experiences aged 13–17 years old. Analysis was conducted using reflexive thematic analysis.ResultsThe results described adolescents reading the signs in the guided interaction between them and the school nurses. Reading the signs illustrated the adolescents' continuous interpretation of the interaction with the school nurse, and their decisions on how to respond throughout the health visit. These interpretations influenced the adolescents' shifting willingness to talk about their health and how they adapted to the space of participation provided by the school nurse. The interpretation also influenced their experiences of health visits as focusing on their health without making them feel singled out.ConclusionAlthough individual considerations might be warranted in health visits with adolescents with migration experiences, the results indicate that similarities in intrapersonal communication in various encounters between adolescents and health professionals might be greater than any differences. Healthcare encounters with adolescents with migration experiences might thus need to be conducted with an awareness that adolescents read the signs in the guided interaction and that similarities in this interaction are greater than any differences.

Abstract

As sustainability scientists increasingly put forward the relevance of process‐relational approaches to make sense of social‐ecological phenomena, an inquiry on which methods would fit a process‐relational approach is necessary.

This paper discusses how a process‐relational approach can be applied to traditional qualitative research methods, namely interviews and coding and the tensions associated with it.

Process‐relational perspectives share commonalities with interpretative approaches but also present specific characteristics, such as the importance of material aspects and the understanding of the phenomenon as a moment in which different elements become defined respective to each other.

The paper uses data and researchers' experiences from an action research project seeking to support collective action among coastal communities affected by environmental changes in Kenya and Mozambique.

Upgrading the properties of polylactic acid/luffa fiber biocomposites through the addition of maleic anhydride grafted styrene–ethylene–butylene–styrene impact modifier
Authors: Rahem Zahir , Mayouf Imane , Guessoum Melia 
Published: June 2024

AbstractTo enhance the adhesion at the interface between polylactic acid (PLA) and local luffa fibers (LFs), and improve the properties of these fully biodegradable biocomposites, 10% of maleic anhydride grafted Styrene–ethylene–butylene–styrene (SEBS‐g‐MA) is added to act concomitantly as compatibilizer and toughening agent. PLA/LF and PLA/SEBS‐g‐MA/LF biocomposite materials were manufactured by melt mixing and then characterized by torque assessment, Fourier transform‐infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), and Izod impact test. In accordance with SEM observation, FTIR analysis and torque measurements, the interfacial bonding coupling the PLA chains to LF via SEBS backbones resulted from the chemical reactions between the functional groups of the composites components. This contributed in increasing notably the impact resistance and the thermal stability compared with the biocomposites without SEBS‐g‐MA. In addition, the improvement of the impact strength might be induced by the flexible ethylene‐butylene blocks, which act as impact absorbers due to their rubber‐like behavior.

AbstractIn this work, new nanoadsorbents consisting of polymer‐modified multi‐walled carbon nanotubes (MWCNTs) were used to remove toxic ionic dyes, of methylene blue (MB) and methyl orange (MO), effectively from aqueous solutions. The MWCNTs were coated with polymer brushes of poly(potassium 3‐sulfopropyl methacrylate) (PKSPMA) and poly(2‐methacryloyloxyethyltrimethylammonium chloride) (PMETAC) via surface‐initiated atom transfer‐radical polymerization. The PKSPMA@MWCNTs and PMETAC@MWCNTs delivered removal efficiencies of ~80% at pH 7. Maximum adsorption capacity (qmax) reached 411.62 mg/g for MB using PKSPMA@MWCNTs and 224.60 mg/g for MO using PMETAC@MWCNTs, showcasing the effectiveness of these novel nanoadsorbents. The experimental results were analyzed using adsorption isotherm models (Langmuir, Freundlich, and Temkin) and kinetic models (pseudo‐first‐order, pseudo‐second‐order, and intraparticle diffusion). The Freundlich model provided an excellent fit for MB adsorption on both adsorbents, whereas the Temkin model best described MO adsorption on PKSPMA@MWCNTs and the Langmuir model on PMETAC@MWCNTs. The fitting results showed that the pseudo‐second‐order kinetic model was the most accurate fit for MB and MO adsorption on both nanoadsorbents, suggesting that the removal mechanism was chemisorption. In conclusion, PKSPMA@MWCNTs and PMETAC@MWCNTs demonstrate significant potential as effective adsorbents for dye removal from water, providing a promising approach for water treatment and environmental remediation.

AbstractBackgroundWilms tumour (WT) is one of the common and curable cancer types targeted by the Global Initiative for Childhood Cancer. Tumour excision is essential for cure. This analysis focuses on surgical outcomes of patients with WT in sub‐Saharan Africa.MethodsWe implemented a risk‐stratified WT treatment guideline as a multicentre, prospective study across eight hospitals and six countries. Eligibility criteria were age 6 months to 16 years, unilateral WT, surgery performed after preoperative chemotherapy and diagnosed between 1 January 2021 and 31 December 2022. Data collection included a specific surgical case report form (CRF).ResultsThe study registered 230 patients, among whom 164 (71.3%) had a nephrectomy. Ninety‐eight percent of patients had a completed surgical CRF. Out 164 patients, 50 (30.5%) had distant metastases. Median tumour diameter at surgery was 11.0 cm. Lymph node sampling was done in 122 (74.3%) patients, 34 (20.7%) had intraoperative tumour rupture, and for 18 (10.9%), tumour resection involved en bloc resection of another organ. Tumour size at surgery was significantly correlated with tumour rupture (p < .01). With a median follow‐up of 17 months (range: 2–33), 23 (14.0%) patients have relapsed. Twenty‐two (13.4%) patients abandoned treatment post nephrectomy. Two‐year event‐free survival was 60.4% ± 4.7% with treatment abandonment as an event.ConclusionSurvival post nephrectomy is challenged by treatment abandonment, treatment‐related mortality and relapse. Large tumours after preoperative chemotherapy were associated with a higher risk of tumour rupture. Earlier diagnosis and access to radiotherapy are expected to improve survival.

Published: June 2024

AbstractThe increasing use of glass‐fiber reinforced polypropylene (GFPP) composites in a wide range of applications requiring long‐term service in challenging environments underscores the importance of its long‐term durability. This study aimed to investigate the effect of thermal aging on the long‐term dynamic durability and stress relaxation of GFPP composites. The time–temperature equivalence principle (TTSP) was used to assess the dynamic modulus at various temperatures and frequencies, as well as the relaxation modulus at different temperatures and relaxation times. To better understand long‐term durability behavior, the study also examined the impact of molecular structure on the durability of GFPP. Changes in chemical composition, crystallinity, melting point, and melt flow index of GFPP due to thermal aging were measured and analyzed using Fourier transform infrared spectroscopy, and differential scanning calorimetry, respectively. The results revealed that oxidation led to a decrease in the crystallinity and molecular weight of GFPP. The destruction of GFPP's molecular structure due to oxidation resulted in reduced long‐term durability. While TTSP can predict the long‐term durability of GFPP for decades or even centuries, its application in predicting the long‐term durability of GFPP is more suitable for nonaging conditions.Highlights
Thermal aging reduces glass‐fiber reinforced polypropylene (GFPP's) long‐term durability.
Time–temperature equivalence principle predicts GFPP durability under aging.
GFPP's activation energy drops with thermal aging.
Long‐term GFPP behavior aligns with Williams–Landel–Ferry model.
Predictive models refine understanding of GFPP longevity.
Docosahexaenoic acid ameliorates autistic‐like behaviors by inhibiting oxidative stress and inflammatory response in neonatal maternal separation rats

Published: June 2024

AbstractAutism spectrum disorder (ASD) is a pervasive neurodevelopmental disorder characterized by impaired social interactions and communication, repetitive, or stereotyped behavior. Docosahexaenoic acid (DHA), an essential polyunsaturated fatty acid, has been demonstrated to exert anti‐oxidative stress and anti‐inflammatory properties, while also promoting myelin development and neural differentiation and development. However, it remains uncertain whether DHA can ameliorate autistic‐like behaviors, and if so, the underlying mechanisms are still unclear. Here, we established a neonatal maternal separation (NMS) rat model and treated it with DHA (80 mg/kg/day, i.p.). The results showed DHA treatment significantly alleviated autism‐like behaviors in the NMS rats during their juvenile period. Subsequently, we employed network pharmacology analysis and molecular docking methods to screen potential targets of DHA in ASD therapy. Through Gene Ontology, Kyoto Encyclopedia of Genes and Genomes, and Wikipedia enrichment analysis, we identified anti‐oxidative stress, anti‐inflammatory and JNK signaling pathway that might be associated with DHA‐mediated improvement of autistic‐like behaviors. Furthermore, western blotting assays showed DHA significantly downregulated the expression levels of p‐JNK and c‐JUN, while upregulating the expression levels of NRF2, HO‐1, SOD1, and CAT. In addition, enzyme‐linked immunosorbent assay results showed DHA effectively reduced the production of pro‐inflammatory factors, such as TNF‐α, IL‐6, and IL‐1β. Collectively, our study predicted and validated that DHA exhibits the potential to improve autistic‐like behaviors induced by NMS in rats by suppressing JNK activation and inhibiting oxidative stress and inflammatory response. These findings suggest that DHA may be a potential therapeutic agent for the treatment of ASD.

AbstractThe extracellular matrix (ECM) is composed of collagens, ECM glycoproteins, and proteoglycans (also named core matrisome proteins) that are critical for tissue structure and function, and matrisome‐associated proteins that balance the production and degradation of the ECM proteins. The identification and quantification of core matrisome proteins using mass spectrometry is often hindered by their low abundance and their propensity to form macromolecular insoluble structures. In this study, we aimed to investigate the added value of decellularization in identifying and quantifying core matrisome proteins in mouse kidney. The decellularization strategy combined freeze‐thaw cycles and sodium dodecyl sulphate treatment. We found that decellularization preserved 95% of the core matrisome proteins detected in non‐decellularized kidney and revealed few additional ones. Decellularization also led to an average of 59 times enrichment of 96% of the core matrisome proteins as the result of the successful removal of cellular and matrisome‐associated proteins. However, the enrichment varied greatly among core matrisome proteins, resulting in a misrepresentation of the native ECM composition in decellularized kidney. This should be brought to the attention of the matrisome research community, as it highlights the need for caution when interpreting proteomic data obtained from a decellularized organ.

AbstractThe assessment of residue, absorption, conduction, and degradation of agricultural organosilicon surfactants in the environment is hindered by the lack of information on active ingredients and corresponding quantitative standards for organosilicon spray adjuvants. The spray adjuvant ‘Jiexiaoli,’ a primary organosilicon spray agent in China, was identified as hydroxy (polyethylene) propyl‐heptamethyl trisiloxane (TSS‐H) with 3–15 ethoxy (EO) groups. Purification of TSS‐H was achieved through semi‐preparative separation using high‐performance liquid chromatography (HPLC), resulting in TSS‐H purity exceeding 96%. An accurate residual detection method for nine oligomers (4–12 EO) of TSS‐H in rice roots, stems, leaves, and culture solution samples was developed using HPLC tandem high‐resolution mass spectrometry (HPLC‐HRMS). Recoveries for nine oligomers of TSS‐H in the four matrices ranged from 80.22% to 104.01%. Foliar application experiments demonstrated that TSS‐H did not transfer from the upper to the lower parts of the rice plant. The half‐lives of each oligomer (4–12 EO) in leaves were less than 3.21 days. Root application experiments revealed a root concentration factor (RCF) ranging from 0.20 to 0.56, a biological enrichment factor (BCF) ranging from 0.36 to 0.68, a transpiration factor (TSCF) ranging from 0.069 to 0.086, and a transport factor (TF) ranging from 0.08 to 0.43. These results indicated that TSS‐H could be absorbed by rice roots and conducted to the above‐ground parts of rice plants. This study fills the data gap in the environmental risk and food safety assessment of agricultural silicone spray adjuvants. © 2024 Society of Chemical Industry.

Published: June 2024

AbstractEmploying the constructs of density functional theory (DFT) and the Nonequilibrium Green's Function (NEGF), the investigation extensively explores the electronic and transport properties of zigzag graphene nanoribbons (ZGNRs) doped with vanadium (V). Notably, this inquiry unveils that strategic doping can transform V‐doped ZGNRs into spintronic nanodevices with distinctive transport attributes. Initially, the simulations showcase remarkably high spin‐filtering efficiencies (SFEs) at certain bias voltages. Furthermore, a giant magnetoresistance (GMR) peaking at 6.87 10 is detected. In conclusion, the examination discerns a spin rectifier that exhibits a significant rectification ratio (RR) of 9.62 10. This research delineates a viable trajectory for the refinement of high‐performance spintronics in ZGNRs via vanadium doping. The implications of this study indicate that the model harbors considerable promise for application in miniature spintronic devices.

Published: June 2024

AbstractSatellite‐to‐ground quantum communication constitutes the cornerstone of the global quantum network, heralding the advent of the future of quantum information. Continuous‐variable quantum key distribution is a strong candidate for the space‐ground quantum communication due to its simplicity, stability, and ease of implementation, especially for the robustness of space background light noise. Recently, the discrete‐modulated continuous‐variable protocol has garnered increased attention, owing to its lower implementation requirements, acceptable security key rate, and pronounced compatibility with extant infrastructures. Here, key rates are derived for discrete‐modulated continuous‐variable quantum key distribution protocols in free‐space channel environments across various conditions through numerical simulation, revealing the viability of its application in satellite‐to‐ground communication.
Topological Phase and Tunable Quantum State Transfer of Su–Schrieffer–Heeger Chain with an Embedded Quantum Ring

Published: June 2024

AbstractAn extended Su–Schrieffer–Heeger (SSH) model consisting of an SSH chain with an embedded quantum ring (QR) is investigated. In the case of two SSH chains with a symmetric distribution with respect to QR, by calculating the real‐space winding number and energy spectrum, the hopping amplitude‐induced topological phase is discovered. The probability distributions of gap states and the relationship between energy and magnetic flux prove the existence of the Aharonov–Bohm effect in the QR. Moreover, in the case of asymmetric distribution, the model possesses a zero‐energy mode within the energy gap, and it is found that it can realize quantum state transfer. By adjusting the connection site between the right SSH chain and QR, the direction of the output port can be flexibly engineered. Furthermore, it is shown that high‐fidelity quantum state transfer can still be achieved with the increasing of the system size. The tunable quantum state transfer based on the zero‐energy mode can be equivalent to a topological tunable directional switch with properties of non‐directional transfer. This work provides an approach for studying topological phase transition and tunable topological devices in an SSH chain with an embedded QR.
