AimsOver time, the locking mechanism of Modular Universal Tumour and Revision System (MUTARS) knee arthroplasties changed from polyethylene (PE) to polyether-ether-ketone Optima (PEEK) and metal-on-metal (MoM) in an attempt to reduce the risk of mechanical failure. In this study, we aimed to assess the cumulative incidence of locking mechanism revision for symptomatic instability by type of material, and assess potential associated risk factors.MethodsThe MUTARS Orthopaedic Registry Europe was used for a retrospective review of 316 patients (54% male (n = 170), median age 44 years (IQR 23 to 61)) who underwent a MUTARS knee arthroplasty for oncological indications between December 1995 and January 2023. The minimum follow-up was 12 months, and the median follow-up was 7.9 years (IQR 3.3 to 13.0). A competing risk model was used to estimate the cumulative incidence of first locking mechanism revision with death and revision for any other reason as competing events. Possible risk factors were assessed employing a univariate cause-specific hazards regression model.ResultsSymptomatic instability of the hinge or locking mechanism due to wear (n = 20) or breakage (n = 14) occurred in 34 patients (11%): 9% of PE (n = 4/45), 20% of PEEK (n = 9/44), and 9% of MoM locking mechanisms (n = 21/227). The cumulative incidences of revision for instability due to wear or locking mechanism breakage at two, five, and ten years were 0%, 5% (95% CI 1 to 15), and 5% (95% CI 1 to 15) for PE, 5% (95% CI 1 to 14), 14% (95% CI 5 to 26), and 16% (95% CI 7 to 29) for PEEK, and 0%, 3% (95% CI 1 to 6), and 10% (95% CI 5 to 16) for MoM. With PE as the reference category, the cause-specific hazard ratio for PEEK and MoM were 3.6 (95% CI 1.1 to 11.9; p = 0.036) and 3.2 (95% CI 1.1 to 9.5; p = 0.043), respectively. Age, BMI, resection length, and extra-articular resections were not associated with the time to locking mechanism revision.ConclusionAlterations in prosthetic materials have not decreased the revision risk for locking mechanism failure. Besides locking mechanism material, no other patient- or prosthesis-related risk factors for locking mechanism failure were identified. Improvement of the locking mechanism is warranted since revision exposes patients to the risk of serious secondary complications.Cite this article: Bone Joint J 2025;107-B(2):239–245.
Preventing pressure sores after hip fracture
Authors: Costa Matt L. , Greenwood Clare , Nixon Jane 
Published: February 2025

Hip fractures commonly occur in older patients, with high levels of frailty and comorbidity. Many of these patients have limited mobility before their fracture, and even after surgery, their mobility may remain limited. It is therefore not surprising that they are at a high risk of developing pressure sores, particularly on their heels, and a variety of devices and interventions have been proposed to reduce this risk. Foam or air mattresses, designed to reduce contact pressure on the patient’s whole body, are now routinely used in many healthcare systems. However, there is wide variation in their design. We developed the WHiTE 14;PRESSURE 3 trial to address the lack of evidence in this area. This is a three-arm multicentre randomized trial including health economic evaluation and recruiting patients from NHS hospitals in the UK. The trial compares standard strategies for the prevention of pressure sores with standard care plus a constant low-pressure device and with standard care plus a heel off-loading device. This annotation describes the development of this trial.Cite this article: Bone Joint J 2025;107-B(2):135–138.

AimsLoosening of the glenoid component in the long term remains an important complication of the anatomical total shoulder arthroplasty (aTSA). The aim of this study was to explore the bony integration of a hybrid glenoid component based on an analysis of CT scans.MethodsIn a prospective multicentre study, patients who underwent primary aTSA, whose hybrid design of glenoid component included a fully-polyethylene flanged upper peg and a porous-coated titanium lower peg, and who were reviewed with CT scans between 12 and 24 months postoperatively, were included. Two independent observers reviewed the scans. Bony integration of the upper peg was scored as described by Arnold et al, and integration of the lower peg was scored as described by Gulotta et al. Perforation of the glenoid vault in any plane was also assessed.ResultsFrom an initial group of 120 aTSAs in 116 patients, 104 CT scans were analyzed in 100 patients (four bilateral shoulders, mean age 66 years (SD 11), 62 female and 38 male). Osteolysis around the upper peg was found in 32 patients (32 aTSAs; 31%). Of the remaining patients, 72 had a mean Arnold score of 5.6 points (SD 0.9), and 70 (67%) had perfect integration. The lower peg had a mean Gulotta score of 6.5 points (SD 1.4). There was perfect integration of the lower peg in 70 patients (70 aTSAs; 67%). A total of nine patients (nine aTSAs; 9%) had no bony integration at either peg. There was perforation of the glenoid in an anterior or posterior direction at the level of the upper peg in three and 28 patients, respectively. This occurred at the level of the lower peg in 11 and 18 patients, respectively. The inter- and intraobserver reliability was good (k = 0.782 and 0.86, respectively). No implant breakage occurred at a mean follow-up of 16 months (12 to 24). The clinical outcome was satisfactory at a mean follow-up of 32 months (24 to 35), as assessed by a visual analogue scale score for pain, the Constant-Murley score, Subjective Shoulder Value, and American Shoulder and Elbow Surgeons score.ConclusionShort-term CT scan analysis of a new hybrid anatomical glenoid component found perfect bony integration around the lower porous coated titanium peg in 90% of patients. The upper polyethylene flanged peg had bony integration in 70 patients (70 aTSAs; 67%). Longer follow-up is needed to analyze the rate of survival of this component. The short-term clinical outcome was satisfactory.Cite this article: Bone Joint J 2025;107-B(2):181–187.

Authors: Kopani Albion , Kopani Xhevdet 
Published: February 2025

The insurance industry in Albania is a sector that consistently receives significant attention in the overall financial industry and plays a crucial role in fostering a culture of insurance among the populace. Year after year, these companies have expanded their presence to the clients, and what is most important, they have expanded the products that they are selling to the clients.
This paper aims to analyze the historical development trends of the Albanian insurance industry, taking into account its significance for a developing economy. Additionally, empirical models will be constructed to predict the values of gross written premiums over a four-year period. The methodology that will be used consist of the analyses of SARIMA and Holt-Winter models to prevent the prediction of the four year period on gross written premiums (GWP) on the life insurance industry in Albania. These models and the comparison between them will prevent a better understanding of the future life insurance in Albania. Those results will help all participant actors of the industry to contribute to a safe and secure environment for the people. Also, the result will help to see the trend and lead the government and companies to prevent the impact of economic sustainability. The conclusion from this paper is that the years from 2024 to 2027 life insurance will grow

Published: February 2025

The purpose of this study is to determine trends and the current state of the gender issue, as well as the impact of different gender factors, taking into account the period of COVID-19, on the level of Ukrainian GDP compared with the countries of the world in modern conditions and to propose appropriate recommendations for the activation and stimulation of women’s participation in business. The authors emphasize that women are disproportionately affected by various social crises: climate change, wars, conflicts and human rights violations etc. The authors analyze the Ukrainian Gender Inequality Index in and make a conclusion that it more than halved during the last decades. The reason for this, especially in recent years, was the COVID-19 pandemic and the subsequent full-scale Russian invasion of Ukraine that had a very negative impact on business. The authors note that Ukraine is situated in 35th place in the European ranking of countries concerning the value of the Gender Inequality Index. A large number of women are generally not involved in the labor market or other economic activities. At the same time, a continuing consequence of the Russian full-scale invasion of Ukraine was a noticeable lack of qualified personnel on the labor market. This is due to the involvement of exclusively men in certain sectors of the economy and their mobilization. The results of the regression analysis indicate that economic participation has the greatest impact on GDP among all the components of the Global Gender Gap Index in the USA, Canada and Poland. Educational attainment is situated on the second place. As for Ukraine, the authors show that as the level of participation of women in the labor force increases, Ukrainian GDP also increases. Taking into account the results of the calculations, the authors conclude that gender factors have a direct impact on the country's economy

Published: February 2025

Currently, students are competing to join organizations based on their interests for various purposes. However, it turns out that not all students are committed while joining the organization. It is definitely detrimental to the organization, as well as the students themselves. This research aims to determine the commitment of student volunteers and their suitability for interacting with each other. This research method is quantitative correlational. The subjects in this research were 201 final year students who were volunteer members of an organization. They had previously been selected using a purposive sampling technique. The measuring instruments used in this research are the Affective Commitment Scale, Self-Regulation Scale, and Perceived Employability Scale. This study uses multiple linear regression statistics and uses the SPSS series 16 computer as an aid in processing data. The results of this research indicate that self-regulation and perceived employability have a partial or simultaneous relationship with student volunteer commitment.

Quantifying and combining uncertainty for improving the behavior of Digital Twin Systems
Authors: Deantoni Julien , Muñoz Paula , Gomes Cláudio , Verbrugge Clark , Mittal Rakshit , Heinrich Robert , Bellis Stijn , Vallecillo Antonio 
Published: February 2025

Abstract
Uncertainty is an inherent property of any complex system, especially those that incorporate physical parts or operate in real environments. In this paper, we focus on the Digital Twins of adaptive systems, which are particularly complex to design, verify, and optimize. One of the problems of having two systems (the physical one and its digital replica) is that their behavior may not always be consistent. In addition, both twins are normally subject to different types of uncertainties, which complicates their comparison. In this paper we propose the explicit representation and treatment of the uncertainty of both twins, and show how this enables a more accurate comparison of their behaviors. Furthermore, this allows us to reduce the overall system uncertainty and improve its behavior by properly averaging the individual uncertainties of the two twins. An exemplary incubator system is used to illustrate and validate our proposal.
Test engines for the asset administration shell
Authors: Otto Björn , Kleinert Tobias 
Published: February 2025

Abstract
The Asset Administration Shell (AAS) is a standard for Digital Twins, a key element of Industry 4.0. In order to realize interoperability as its central prerequisite, manufacturers must implement the formal AAS metamodel specification correctly down to the last detail. To ensure this, conformance testing procedures should be defined and carried out as appropriate quality measures. This article presents comprehensive approaches to carry out formalized metamodel conformance tests for the AAS and its software components by describing the AAS Test Engines. First, the AAS software ecosystem is analyzed providing a systematic categorization of existing AAS software components. Based on these findings, basic building blocks and test setups needed for AAS conformance testing are identified. Then, implementation of these building blocks in the AAS Test Engines is described. Finally, usage, findings and limits of the presented methods based on a real-world case study from the AAS community are illustrated.
Wann ist ein Mann ein (Ehe-)Mann? Der Nachweis gleichgeschlechtlicher Ehen und der Geschlechtsfluidität in der römischen Kaiserzeit
Authors: Coert Jean 
Published: February 2025

Zusammenfassung
Dieser Text bricht mit der breit akzeptierten Forschungsannahme, dass in der Antike Ehen nur zwischen Frauen und Männern bestehen konnten, indem er untersucht, ob Ehen zwischen gleichgeschlechtlichen Partnern im Römischen Reich existiert haben. So wird an mehreren dokumentierten Fällen und Quellenpassagen, die teilweise bisher nicht in der Forschung berücksichtigt wurden, gezeigt, dass Personen intendiert im Konsens ihrer Zeitgenossen ihren sozialen Geschlechtsstatus wechseln konnten und im Rahmen ihrer neuerworbenen geschlechtsspezifischen Privilegien eine Ehe mit einer Person des gleichen biologischen Geschlechts führen konnten. Damit verbunden wird auch die Einordnung des Phänomens durch zeitgenössische Autoren nachverfolgt, denen diese Praktik zumindest teilweise gut vertraut war und die sie auch ausgiebig kritisierten. Warum diese Formen der Geschlechtsfluidität und der gleichgeschlechtlichen Ehen trotz der Kritik zunächst Bestand hatten und Duldung erfuhren, dann in der Spätantike kriminalisiert wurden und damit als Phänomen die Antike nicht überdauern konnten, wird abschließend besprochen.
A novel design methodology for preventing dislocation in the Zig-zag shroud
Authors: Du Chenhong , Wang Yanrong , Li Di , Jiang Yuanyuan 
Published: February 2025

Abstract
Dislocation is defined as the inability of shrouded blades to return to their normal position after deformation caused by an external force. Numerous methods exist for designing shrouds of turbine engines, targeting structural strength, sealing performance, contact interface wear, or damping. However, these designs often fail when dislocation occurs, which is a common issue in engineering. Limited methods focus on preventing shroud dislocation. In this article, we classify the dislocation of zig-zag shrouds into two patterns. A method for calculating the equivalent stiffness of the contact interface is provided to determine the clearance of non-working surfaces. Through a series of static analysis, we introduce a method to adjust the shroud shape and assess its capability in preventing dislocation. All methods are tested on a low-pressure turbine blade.
Envoltorio y pedernal: Octavio Paz y Luis Cardoza y Aragón sacando chispas. O de las intuiciones ch’ixi sobre la identidad en El Laberinto de la soledad y Guatemala las líneas de su mano
Authors: Urízar Julio 
Published: February 2025

This work compares the metaphors associated with mestizo identity and subjectivity in two essays from Latin American literature: El laberinto de la soledad (1950) by Octavio Paz and Guatemala, las líneas de su mano (1955) by Luis Cardoza y Aragón. The notions of identity and subjectivity are read as enveloping and sparkling processes, where discomfort and contradiction are inherent to the affirmative process of the Mexican and Guatemalan experiences. It is concluded that the texts express in their most poetic facet an experience of mestizo identity and subjectivity similar to Ch’ixi subjectivity, proposed by the Bolivian sociologist Silvia Rivera Cusicanqui as a space of friction and discomfort that does not allow the pacification of unity, open to the possibility of new and plural recognitions.
