Published: February 2025

Background
Preoperative diagnosis of malignancy in patients with pancreatic cystic lesions (PCLs) remains challenging. The aim of this study was to assess the sensitivity, specificity, and positive and negative likelihood ratios (LRs) of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA)-based cytology in differentiating malignant PCLs from benign PCLs.

Methods
A comprehensive search was performed in multiple databases in November 2023. Studies differentiating benign and malignant PCLs via EUS-FNA-based cytology, in which the results were compared with those of surgical excision histopathology, were included in this meta-analysis. Data from the selected studies were pooled to summarize the sensitivity, specificity, positive and negative LRs, diagnostic odds ratios and summary receiver operating characteristic (SROC) curves.

Results
We included 755 patients from 15 distinct studies who underwent EUS-FNA-based cytology and had a histopathological diagnosis. The pooled sensitivity and specificity in diagnosing malignant PCLs were 0.62 (95% CI, 0.42–0.78) and 0.96 (95% CI, 0.91–0.98), respectively. The positive and negative LRs for diagnosing malignant PCLs were 16.3 (95% CI, 7.2–37.0) and 0.40 (95% CI, 0.25–0.64), respectively. The area under the curve (AUC) was 0.94 (95% CI, 0.91–0.95).

Conclusions
EUS-FNA-based cytology has overall high specificity, medium sensitivity and good diagnostic accuracy in differentiating malignant from benign PCLs. Further research is needed to improve the overall sensitivity of EUS-FNA-based cytology for the diagnosis of malignant PCLs.
Biomechanical comparison of various bone reduction forceps in interfragmentary compression and area of compression in an experimental model of canine lateral humeral condylar fractures
Authors: Baskette Madison , Ferrigno Cassio Ricardo Auada 
Published: February 2025

Objective
To compare contact area and interfragmentary compression generated by Vulsellum forceps, Patellar forceps, Kyon FineTouch forceps, point-to-point forceps with soft-locking mechanism, and point-to-point forceps with speed-locking mechanism in simulated lateral humeral condylar fractures in canine cadavers.

Study design
Ex-vivo biomechanical study.

Materials and methods
Seven cadaveric canine humeri with simulated lateral humeral condylar fractures were used in this study. A stress-sensitive film was placed at the fracture gap and five different bone reduction forceps were used to reduce the fractures to their maximum pressure before failure occurred. The compression and interfragmentary compression area were recorded during the entire compression interval and compared after the pressure had reached a plateau.

Results
Patellar forceps generated the highest interfragmentary compression, followed by Vulsellum forceps. Compression generated by both the Patellar and Vulsellum forceps were significantly higher than point-to-point forceps with soft-lock, point-to-point forceps with speed lock, and Kyon forceps (P = 0.0008, 0.0084). No statistically significant difference was observed in the areas of compression among all forceps types.

Conclusion
Patellar and Vulsellum forceps generate a greater interfragmentary compression compared to Kyon FineTouch forceps and point-to-point forceps with both speed and soft-locking mechanisms in this experimental lateral condylar fracture model.
Usability of a digital mindfulness training program for smoking cessation: A mixed-method single-center pilot study protocol (HowToMind)
Authors: Demina Anastasia , Soudry-Faure Agnès , Petit Benjamin , Meunier-Beillard Nicolas , Trojak Benoit 
Published: February 2025

Background
Tobacco use is one of the leading causes of preventable disease and death worldwide. Despite the availability of evidence-based pharmacological treatments, only a small number of individuals with tobacco use disorder achieve long-term abstinence after smoking cessation. This highlights the need to enhance existing interventions. In this protocol, we describe our single-center mixed-method trial, HowToMind, conducted in Dijon, France. This trial aims to investigate the usability and acceptability of a digital mindfulness-based intervention designed to complement standard smoking cessation treatment to potentiate its effects.

Methods
We will include 60 adults seeking treatment for tobacco use disorder, as defined by DSM-5 criteria, who wish to quit smoking and own a smartphone. All participants will receive a combination of transdermal and oral nicotine replacement therapy and will be introduced to an eHealth app that provides a digital equivalent of an 8-week mindfulness training program. The acceptability of the initial version of our app will be assessed based on usage frequency, and usability will be evaluated using the Mobile App Rating Scale (French version). A participatory approach will be employed through focus groups conducted at the end of the 8 weeks of app use, aimed at co-constructing the final version of the app based on participant feedback.

Discussion
Our pilot mixed-method trial seeks to explore the usability and acceptability of our app, making necessary adjustments to its content and functionality based on participant feedback before its implementation in a large randomized controlled trial assessing the app’s potential to enhance the effects of standard treatment.

Published: February 2025

Abstract

Objectives
Infertility is a global medical problem with annually increasing prevalence. In China, since the implementation of the universal two-child policy, the demand for fertility treatments continues to rise. During treatment, women with infertility may undergo various negative emotions, which can affect the treatment outcome, or even lead to refusal or discontinuation of treatment. However, maintaining a positive psychology can help alleviate negative emotions and increase patients’ confidence during the treatment process. The aim of this study is to investigate the subjective well-being (SWB) of infertile women undergoing the treatment of in vitro fertilization and embryo transfer (IVF-ET), and to analyze the factors affecting their psychological status during IVF-ET treatment.

Methods
In this study, 1,042 subjects were selected through convenience sampling from female subjects who received IVF-ET treatment from November 2021 to April 2022 at the Reproductive Medicine Center of a Grade A tertiary hospital in Beijing. All subjects were required to complete a basic profile questionnaire, self-esteem scale, fertility problem inventory (FPI), and SWB scale. A stepwise multiple linear regression was performed to analyze the factors impacting SWB.

Results
The mean score of SWB given by subjects was 88.97±12.08 (mean±standard deviation (SD)). The main factors influencing SWB included age, occupational status, personal monthly income, duration of infertility, self-esteem, and fertility stress (p<0.05), which together explain 51.5 % of total variance.

Conclusions
Overall, female subjects receiving IVF-ET treatment have a moderate level of SWB, which is affected by various factors. Our study suggests that clinical care should identify factors influencing SWB and provide interventions to enhance SWB of infertile women during IVF-ET treatment in order to encourage them to face treatment positively.

Published: February 2025

Abstract
To enhance patient care, it is necessary to increase the lifetime of double modular hip endoprostheses with tapered junctions. One approach to increasing the lifetime of components is to adjust the residual stress state to the load. Therefore, this study investigates the influence of process parameters and the effect of their interaction on the residual stresses of neck adapters manufactured from CoCr28Mo6. With the investigated process parameters, compressive residual stresses are present after turning. This study reveals the interaction and issues between surface roughness and the high bending of the surface due to the small radius of the samples in the measurement of residual stress.

Abstract
In recent years, the metal processing industry has undergone a massive rethinking in terms of energy use. With the phase-out of nuclear energy, Germany wants to take responsibility and embark on a more sustainable path to green electricity. Not only due to the discontinuation of fast-available nuclear energy, but also due to the increasing demand for electrical energy and the geopolitical situation, the costs for production are continuously rising. Furthermore, the use of fossil fuels has come under criticism in the face of current climate policy discussions, and the procurement of fossil fuels such as natural gas has experienced a significant price increase due to the current geopolitical situation. A more efficient use of energy and resources is therefore essential, also with regard to socio- and environmental factors and, in particular, climatic aspects.
In this work, a standard industrial gas nitriding process is examined with regard to its key energy figures and potential savings are identified. On the basis of these, the significance of the heating of the components, the insulation technology and other process-relevant energy flows is determined. It was found that, on the basis of conservative calculation models, the heating of these industrial furnaces types is among the largest energy consumers, whereas only a smaller part is required for treating the components. Furthermore, the majority of the electrical power provided dissipates as power loss from the heat treatment process.

Abstract
α-UO3 is a common intermediate compound found in the nuclear fuel cycle, yet the exact crystal structure of this material has long been debated. Inconsistent computational and experimental data in previous works has led to varying conclusions between authors. To ensure the validity of our results in this work, the structural and spectroscopic signatures of pure phase α-UO3 are investigated using powder X-ray diffraction and optical vibrational spectroscopy (infrared and Raman). Rietveld refinement of powder X-ray diffraction data on pure phase α-UO3 collected in this work allows us to propose an alteration to the currently accepted C2mm structure (a = 3.9705 Å, b = 6.8553 Å, c = 4.15955 Å, α = β = γ = 90°) for α-UO3 with no uranyl [UO2
2+] bonds. Raman spectra collected using two excitation wavelengths (two instruments using 532 nm and one 785 nm) are presented, and differences with recently published results are discussed. Infrared spectra from two instruments used here agree well with recently published results, but the spectral range encompassed in our data extends past what has been reported with modern techniques. Additionally, we provide tentative vibrational mode assignments based on density functional perturbation theory calculations and resulting phonon eigenvector visualizations. Unexpected features in the optical vibrational spectra of α-UO3 are explained by unique features in the structure we present.
Ein verletzliches Leben. Vulnerable Existenzweisen, performative Praktiken und ihre politische Beziehung
Authors: Lluis Conrad 
Published: February 2025

Zusammenfassung
Der Aufsatz fragt nach der Stellung der Vulnerabilität in der Gesellschaft. Als Ausgangspunkt dienen zwei gegenläufige Verständnisse von Vulnerabilität: einerseits gerinnt Vulnerabilität zu einer scheinbar unveränderlichen sozialen Tatsache, andererseits wird sie ständig politisch herausgefordert. Um diesen Widerspruch aufzulösen, werden zwei konträre Vulnerabilitätsbegriffe sozialtheoretisch so reformuliert, dass sie als Pole eines dynamischen Kontinuums erscheinen. An einem Pol steht Judith Butlers ontologischer Begriff von Vulnerabilität als basale Abhängigkeit von einer Um- und Mitwelt, am anderen Pol das in öffentlichen Debatten dominierende Verständnis von ‚vulnerablen Gruppen‘, die fest und handlungsunfähig scheinen. Die Vulnerabilität bewegt sich stets, so die These, in der Spannung zwischen diesen zwei Polen. Mittels eines von Butler stammenden, aber anhand der Ethnographie der Plattform der Hypothekbetroffenen (PAH) Barcelona analytisch ausgebauten Konzepts der kollektiven Performativität wird zunächst der aktiv-transformative Pol der Vulnerabilität ausformuliert. Im Rückgriff auf die Gender Studies, insbesondere auf Andrea Maihofer, sowie auf Einsichten der konstruktivistischen Disability Studies und der Arbeitssoziologie nach Bahl und Staab wird anschließend der Begriff der vulnerablen Existenzweise eingeführt. Dieser Begriff steht für den passiv-erfahrenden Pol der Vulnerabilität. Der aktive und der passive Pol der Vulnerabilität werden durch eine politische Beziehung verwoben.

Published: February 2025

Abstract
Sericin, a protein extracted from the cocoons of silkworms, has recently become an attractive biomaterial due to its potential as a good candidate for wound healing especially wounds seen in diabetic and immune-compromised patients. This review discusses the special biological nature of sericin such as its water-solubility and inherent moisturizing properties, antimicrobial, and antioxidant activities, which can act synergistically to foster ideal conditions for wound healing. The incorporation of sericin into composite wound dressings along with other natural and synthetic polymers was found to improve the mechanical properties, biocompatibility, and overall therapeutic performance. Moreover, the review draws attention toward sericin-based materials in diabetic wound healing with a focus on promoting rapid tissue regeneration and cell proliferation and enhancing clinical outcomes that conventional therapeutics cannot serve. The review also discusses the challenges associated with the production and application of sericin-based wound dressings and outlines the prospects for this emerging field. As research continues to advance, silk sericin holds the potential to revolutionize wound care, offering innovative solutions for the effective and holistic management of complex wounds.

Published: February 2025

Рассмотрена возможность получения композиционного материала из ферросплава на основе нитридов кремния, алюминия и циркония методом самораспространяющегося высокотемпературного синтеза. Показано что внесение азотсодержащей добавки на основе ферроалюмосиликоцирконии в количестве до 35 масс. % к исходному ферросплаву приводит к увеличению содержания азота, выходу основных нитридных фаз в продуктах горения, замедлению продвижения фронта волны горения и уменьшению максимальной температуры горения. Выявлено, что внесение предварительно азотированного материала более 20 масс. % позволяет перевести режим распространения фронта волны горения в стационарный и получить продукты горения с макрооднородным составом. В условии естественной фильтрации азота горением порошковой смеси на основе ферроалюмосиликоцирконии и азотированного материала получен композит, состоящий из фаз AlN, Si3N4 и ZrN и α-Fe.
The possibility of obtaining a composite material from a ferroalloy based on silicon, aluminum, and zirconium nitrides by the method of self-propagating high-temperature synthesis is considered. It is shown that introduction of a nitrogen-containing additive on the basis of ferroalumosilicozirconium in amounts up to 35% to the initial ferroalloy leads to an increase in the nitrogen fraction, emission of the basic nitride phases in combustion products, deceleration of motion of the combustion wave front, and reduction of the maximum combustion temperature. It is found that introduction of a preliminary nitridized material in amounts of more than 20% makes it possible to convert combustion wave front propagation to a steady regime and to obtain combustion products with a macroscopically homogeneous composition. Under the conditions of natural filtration of nitrogen, combustion of a powder mixture based on ferroalumosilicozirconium and a nitridized material yields a composite consisting of AlN, Si3N4, ZrN, and α-Fe phases.

Представлено исследование процесса механохимического синтеза нитрида титана в условиях двойной механической активации (МА) порошка титана: в аргоне и в газообразном азоте. В экспериментах варьировали времена МА титана в аргоне и в азоте. Анализ морфологий порошковых смесей, данных рентгенофазового и микроанализа показал, что предварительная МА титана в аргоне способствует ускорению механохимического синтеза нитрида титана. Получены аналитические соотношения и даны теоретические оценки, позволяющие прогнозировать процесс двойной механоактивации титана.
A study of the process of mechanochemical synthesis of titanium nitride under conditions of double mechanical activation of titanium powder: in argon and in nitrogen gas is presented. In the experiments, the time of mechanical activation of titanium in argon and nitrogen was varied. Analysis of the morphology of powder mixtures, X-ray diffraction and microanalysis data showed that preliminary mechanical activation of titanium in argon helps to accelerate the mechanochemical synthesis of titanium nitride. Analytical relationships are obtained and theoretical estimates are given that make it possible to predict the process of double mechanical activation of titanium.

Published: February 2025

Pott’s Puffy Tumour (PPT) is an inflammation and swelling of the forehead secondary to osteomyelitis of the frontal bone. Multiple aetiologies are associated with this condition, predominately involving a prior sinus surgery or a direct trauma to the frontal bone. There can be intracranial extension with an epidural, subdural as well as intracerebral abscess. We present the case of an 8-year-old boy who presented with swelling in his forehead secondary to trauma. His general condition was poor, and further evaluation revealed multiple subdural empyemas. Although PPT is rare in this modern era of antibiotics, it should be kept as a differential for any inflammation of the forehead. Timely diagnosis and the appropriate treatment by a multidisciplinary team are indispensable in reducing the morbidity and mortality associated with this case.
A szervezeti adaptabilitás és az otthoni munkavégzés lehetőségének hatása az észlelt stressz, magányosság és általános jóllét kapcsán
Authors: Klajkó Dóra , Csapó Gyöngyvér Virág , Czibor Andrea 
Published: February 2025

Háttér és célkitűzések: A 21. századi szervezeteket a folyamatos és rendkívül gyors változás jellemzi. A világjárvány idején a szervezeti rugalmasság kérdésköre még nagyobb prioritást élvezett, amely a szervezet működésének kulcskritériumát is jelentette egyben. A rugalmasság nemcsak a munkavégzés módjára (online, távmunka, munkaidő-kedvezmények), hanem a szervezeti tanulásra és a változásokra való fogékonyságra is kiterjed. Mindezzel szorosan összefonódva a munkavállalói egészségvédelem és a mentális jóllét is előtérbe került. A korábbi szakirodalmi eredményeket alapul véve jelen kutatás célja volt, hogy feltárjuk a szervezeti rugalmasság különböző aspektusait a munkavállalói jóllét szempontjából. A változásra és tanulásra fókuszáló szervezeti kultúrát, valamint egy rugalmas szervezeti intézkedést, a távoli munkavégzés hatásait vizsgáltuk meg részletesebben. Módszer: Kutatásunk 203 fő magyar munkavállaló bevonásával zajlott, amely során a pandémia után tapasztalt megváltozott munkavégzési sajátosságokat és a munkavállalói jóllét aspektusait vizsgáltuk. Az adatgyűjtéshez a Denison Organizational Culture Profile (OCP) adaptabilitás skáláját, valamint a munkavállalói észlelt stressz kérdőívet (PSS), a WHO általános jóllét kérdőívét (WHO10) és az UCLA Loneliness Scale (Magányosság Skála) 8 itemes verzióját használtuk. Emellett rákérdeztünk arra, hogy a kitöltő az elmúlt két hónap során milyen gyakran végezte a munkáját otthonából. Eredmények: Az adatelemzés során Structural Equation Modeling (SEM) eljárást alkalmaztunk egy elméleti modell felállítása céljából, amely a szervezeti adaptabilitás és az otthoni munkavégzés hatásainak mechanizmusait tárja fel a munkavállalói jóllét látens változói kapcsán. Ezen belül egy multigroup elemzést is végeztünk a nemi különbségek feltárására. Következtetések: A SEM elemzés során erős modellilleszkedést találtunk, illetve kimutatható volt, hogy a szervezeti adaptabilitás pozitívan hat a munkavállalói jóllétre, míg az otthoni munkavégzésnek nincsenek szignifikáns hatásai. A multigroup elemzés során feltárult az otthoni munkavégzés nőkre és férfiakra nézve eltérő hatása. Míg a nők esetében nem találtunk szignifikáns hatást (nem szignifikáns fordított korrelációt igen), addig a férfiak esetében egy közepes erősségű pozitív kapcsolat rajzolódott ki a munkavállalói jóllét kapcsán, amely eredmény illeszkedik a korábbi nemzetközi kutatások eredményeihez is.
Economy and Ethnicity. The Recolta Agricultural Cooperative as a Driver of Local Economic and Social Resilience in the Village of Csanálos
Authors: Szilágyi Levente 
Published: February 2025

AbstractThis study examines the impact of the agricultural cooperative currently operating in Csanálos (Urziceni), a Swabian settlement in Szatmár (Satu Mare), on the local economy and society. Agricultural cooperatives played an important role at the beginning of the process of agrarian transformation after the regime change in Romania. Established on a voluntary basis, the successor organizations to the socialist agricultural collectives were able to offset the impoverishment brought about by re-peasantization or forced peasantization during the long transition period, provided a stable financial basis for communities in the difficult periods following the regime change, and, often taking over state responsibilities, represented social cooperation and trust-based social localism. On the other hand, they took advantage of their monopolistic position to hinder the emergence of individual and family farmers. The risk-averse, self-reliant economic model of the cooperatives evokes the self-sufficient organization of peasant farms. Cooperatives can thus be seen as a very specific form of post-socialist post-peasant production system.
