Hip-spine syndrome from the perspective of radiology: correlations between hip joint disease and lumbar spine MRI findings
Authors: Pan Haibin , Wang MingLiang , Tang Jianyan , Wu Shiming , Li YueHua , Li Xiaobing
Published: January 2025

Background

Hip joint (HJ) pain, which may be caused by lumbar disease, is a common complaint.

Purpose

To investigate the prevalence and specific correlations between various HJ diseases and lumbar spine magnetic resonance imaging (MRI) findings in patients with HJ pain.

Material and Methods

Patients with the chief complaint of HJ pain who had both HJ MRI and lumbar MRI were retrospectively included. According to the existence of HJ disease, patients were divided into the following groups: non-HJ disease; osteoarthritis (OA); femoroacetabular impingement (FAI); ischiofemoral impingement (IFI); greater trochanter pain syndrome (GTPS); and other diseases. The prevalence of major lumbar MRI findings was compared. Correlations between HJ disease and major lumbar MR findings were explored.

Results

A total of 585 patients were included, of which 566 (96.8%) had major findings on lumbar MRI. The HJ disease group was more likely to be female and had more spondylolisthesis, while the non-HJ disease group had more low back or leg pain. The OA group was older and correlated with lumbar spinal stenosis (contingency coefficient = 0.164) and spondylolisthesis (contingency coefficient = 0.095). The FAI group was younger, had more male patients, and correlated with lumbosacral transitional vertebrae (contingency coefficient = 0.122). The IFI group was older, had more female patients, and correlated with facet joint osteoarthritis (contingency coefficient = 0.168). The GTPS group was older, had more female patients, and correlated with spondylolisthesis (contingency coefficient = 0.097).

Conclusion

Major lumbar MRI findings were frequently observed in patients with hip pain, even in patients without HJ disease. Specific lumbar MRI finding correlated with different HJ disease.

Published: January 2025

Behçet’s disease (BD) is a rare systemic vasculitis that is characterized by recurrent oral and genital ulcers, uveitis, and skin lesions. Although neurological involvement is a known complication, ischemic stroke remains uncommon. Herein, we report a 37-year-old Kuwaiti woman who experienced recurrent ischemic stroke with no traditional risk factors. Imaging studies, including magnetic resonance imaging and angiography, confirmed the diagnosis of recurrent ischemic stroke and identified the underlying vasculitic changes. A detailed examination revealed a history of recurrent orogenital ulcers, leading to a diagnosis of BD. High-dose corticosteroids, azathioprine, and antiplatelet treatment were effectively used to manage her acute strokes and underlying vasculitis, thus preventing further thrombotic events. Our case report underscores the difficulties of diagnosing BD with ischemic stroke as the initial manifestation and emphasizes the importance of a multidisciplinary approach that involves rheumatologists, neurologists, and radiologists to create an effective treatment plan. Our findings also underscore the need for medical practitioners to be more knowledgeable about ischemic stroke in young patients without risk factors from endemic areas of BD, and to develop effective therapy plans. Our review of the English literature indicates that this is only the fifth report of stroke as the first presentation of BD.

Acute pancreatitis (AP) is a life-threatening condition, with a higher mortality rate in men than women and in which estrogens might play a protective role. This study aimed to investigate sex-dependent differences in a mouse model of caerulein-induced AP. Thirty-six C57BL/6J mice (19 females and 17 males) were treated intraperitoneally with phosphate-buffered saline or caerulein, and sacrificed 12 hours, 2 days, or 7 days after the last injection. Blood was collected for amylase, lipase, and glucose determination. Severity and extent of inflammation, apoptosis, and acinar to ductal metaplasia (ADM) in pancreatic tissue were scored histologically and total macrophages, major histocompatibility complex (MHC)-II+ cells, M2 macrophages, T and B cells, neutrophils, apoptosis, and ADM were marked immunohistochemically and quantified by digital image analysis. Serum amylase had a peak at 12 hours, without differences between the sexes. In females, pancreatitis reached a peak at 12 hours with a fast recovery while, in males, the peak was delayed to day 2 with residual apoptosis still present. Macrophages were the main inflammatory cell population, followed by T cells, B cells and neutrophils, without differences between sexes. In males, CD206+ cells and apoptosis were higher at both days 2 and 7, and cytokeratin-19+ (CK19+) ADM was higher at day 7 compared with females. The results of this study revealed a faster onset and resolution of caerulein-induced AP in female mice compared with male mice, supporting a sex-dependent modulation of acute pancreatitis.
Effect of TiO2 on melting and crystallisation properties of CaF2(50%)-CaO-Al2O3-MgO(3%)-ZrO2(4%) electroslag
Authors: Ju JianTao , Zhou Yuan , Yang YongKun , Luo Ning , Guo WenKe
Published: January 2025

This study investigates the effect of highly fluorinated electroslag with TiO2 content of 0%, 3%, 6% and 9% on the melting process, crystallisation kinetics and crystalline product structure by using STA, XRD and SEM-EDS techniques. The results demonstrated a gradual decrease in the melting temperature, heat of fusion and first crystallisation temperature of the slag as the TiO2 content increased. The main precipitation phases in the slag are Ca12Al14O32F2, CaF2, CaZrO3, CaTiO3, (Ca, Zr, Ti)O2 and MgO. The larger the ratio of TiO2:ZrO2, the higher the precipitation rate of multi-faceted CaTiO3. The precipitation of dendritic CaZrO3 was also gradually suppressed. Crystallisation kinetic analysis revealed that the slag exhibited the highest activation energy for crystallisation at a TiO2 content of 6%. These findings have a positive impact on determining the TiO2 content in the electroslag and enhancing the surface quality of the ingot.
Financial geography II – green finance and climate transition
Authors: Lai Karen PY
Published: January 2025

This second progress report on financial geography focuses on green finance and research on financing climate transition and environmental challenges. It explores theoretical approaches to green finance, with Marxist perspectives on shifting capital-nature relations in broader regimes of capitalist accumulation that are complemented with a Foucauldian lens on biopolitical governmentality. It then examines specific forms of green financial markets and instruments, with financial geographers focusing most strongly on carbon markets, green bonds and catastrophe bonds/insurance-linked securities and the reconfiguration of risks. The final section covers governance and regulation of green finance through a growing assemblage of organisations and programmes, and the evolving roles of state actors and central banks in just climate transition.

Comparison of International Methods to Estimate Maximum Speed Through Roundabouts
Authors: Arries Jared Tyrell , Bruwer Megan Melissa , Krogscheepers Johann Christoff
Published: January 2025

Roundabout operating speed estimation is a critical aspect of safe roundabout infrastructure design, yet existing international guidelines for speed evaluation exhibit inconsistencies and limited agreement with actual observed speeds at roundabouts. This study provides a comprehensive evaluation of five existing international guidelines and their implications for roundabout safety. This study focused on the discrepancies between estimated and observed fastest path speeds by conducting Passing–Bablok regression analyses of speed estimates evaluated from guidelines from Australia, the Netherlands, the United Kingdom, the USA, and South Africa, and speeds observed at 29 roundabouts, encompassing both single- and double-lane configurations. This study represents the most extensive comparison between methods used in various countries for fastest path analysis and is the first instance of empirical fastest path speed assessment. A widening of the confidence intervals around regression lines at higher speeds indicated poor agreement between estimated and observed speeds. All minimum observed speeds exceeded estimated design speeds for double-lane roundabouts signaling a failure of current design methodologies to sufficiently reduce speeds. The findings of the study uncover a systematic tendency for international guidelines to underestimate operating speeds lower than 60 km/h and overestimate higher speeds, posing significant safety concerns. This discrepancy not only challenges prevailing assumptions about roundabout safety but also highlights the potential for a false sense of security among designers. By shedding light on these discrepancies, insights are gained to inform more accurate speed estimation methods, thereby contributing to improved design practices and sufficient speed reduction at roundabouts.
Extended Pedestrian Evacuation Model Considering Multiple Evacuation Behaviors
Authors: Qinghua Mao , Yang Li , Rongfu Yu , Bing Zhao , Wenteng Huo
Published: January 2025

A variety of behaviors can exist in pedestrian evacuation, altruistic, competitive, indifferent, and so forth. Understanding the psychological state of pedestrians and the various evacuation behaviors that arise is important because it plays a critical role in understanding the entire evacuation process. In this paper, an extended cellular automata model is developed to study the different behaviors of pedestrians in evacuation. Pedestrians are classified by psychological and physical heterogeneity, including helpful pedestrians, aggressive pedestrians, apathetic pedestrians, and vulnerable pedestrians. In this model, pedestrians are affected by static fields, dynamic fields, helper fields, and attack fields. In addition, the pedestrian view is affected by the density and position of movement of surrounding pedestrians. And, pedestrian movement, small group movement, helping behavior, aggressive behavior, and apathetic behavior are also considered simultaneously. Numerical simulations were conducted to discuss the pedestrian evacuation problem under multiple behaviors, and the effects of helping behavior, the number of attackers, attack force, pedestrian density, and apathetic behavior on the evacuation process were analyzed in detail. The results of the study can provide reference and guidance for the development of pedestrian evacuation strategies in the presence of helping, aggressive behavior events, and reducing casualties.
Combined Revealed- and Stated-Preference Survey to Understand the Impact of Multi-Source Real-Time Information on Travel Mode Choice
Authors: Hridoy Daud Nabi , Tasnia Rifa , Pandey Venktesh , Rijal Birat , Hasnine Md Sami
Published: January 2025

This study presents a combined revealed preference (RP) and stated preference (SP) survey to understand travelers’ mode choices under the influence of real-time information for different activity types and trip lengths. The D-efficient method is adopted to generate SP scenarios. The empirical data for this study came from a “Survey to understand the impact of ICT on transportation choices” (SUIT; ICT = information and communication technology), conducted in July 2023 in the Washington, DC metro area and the Charlotte metro area, North Carolina (NC), USA A combined RP–SP multinomial logit and mixed logit model (MxL) capturing the error components have been estimated based on the collected data. The model results reveal that daily parking costs significantly impact individuals’ mode choices and tend to discourage driving. Furthermore, real-time information such as the availability of parking spaces at workplaces and metro stations encourages people to prefer drive and park & ride modes. Conversely, information on flash flooding alerts, road closures, and road accidents discourages people from driving, riding as auto-passengers, or taking a transportation network company (TNC) (Uber/Lyft) for trip purposes. Lastly, information on reduced waiting time and disruption plays a significant role in selecting transit and park & ride modes. The results obtained from this study can be beneficial to policymakers when assessing or designing alternative sustainable modes in the presence of real-time information. As its policy finding, the study recommends that transit disruption should be handled carefully to retain loyal customers and achieve various sustainability goals. In the event of transit disruption, alternative sustainable transportation modes should be offered to transit riders.
Does the Addition of a Lateral Extra-articular Procedure to a Primary Anterior Cruciate Ligament Reconstruction Result in Superior Functional and Clinical Outcomes? A Systematic Review and Meta-analysis of Randomized Controlled Trials
Authors: Kan Adrian , English Tayla , Penny Allanah , Franc-Smith Jordan , Tudor Francois , Sattler Larissa
Published: January 2025

Background:

Current research focused on clinical outcomes suggests that lateral extra-articular procedures (LEAPs) can reduce rotational instability and graft failure rates in primary anterior cruciate ligament reconstructions (ACLRs). Limited studies have investigated the functional outcomes after LEAPs, including patient-reported outcome measures, sports participation, and physical performance.

Purpose:

To conduct a systematic literature review and meta-analysis to determine whether the addition of a LEAP to an ACLR results in superior functional and clinical outcomes as compared with an isolated ACLR.

Study Design:

Systematic review and meta-analysis; Level of evidence, 1.

Methods:

Five databases were searched to identify randomized controlled trials comparing clinical and functional outcomes after the addition of LEAPs to an isolated primary ACLR. Study selection was performed in accordance with the PRISMA guidelines (Preferred Reporting Items for Systematic Reviews and Meta-analyses). Assessment of methodological quality for included studies was undertaken using the Cochrane Risk of Bias 2 tool for randomized controlled trials. Studies were eligible for meta-analysis if an outcome measure utilizing similar time points was present across ≥2 studies and reported in mean difference or standard deviation.

Results:

Meta-analysis of 10 studies showed that the addition of LEAPs to an ACLR can reduce rates of rotatory instability (risk ratio, 1.45 [95% CI, 1.17-1.79]; P = .0006; I2 = 0%) and graft rupture (risk ratio, 0.21 [95% CI, 0.08-0.55]; P < .001; I2 = 0%). As supported by studies eligible for meta-analysis, this review showed that the addition of LEAPs to an ACLR can reduce rotatory instability. Short-term morbidity, including increased pain, joint stiffness, and muscle weakness, as compared with isolated ACLRs was resolved by 12 months after surgery.

Conclusion:

ACLR in combination with a LEAP results in superior clinical outcomes when compared with an isolated ACLR. Despite early postoperative outcomes concerning pain and function favoring isolated ACLRs, any negative effects were not still observed 6 months after surgery. A conclusion around the correlation between LEAPs and accelerated knee osteoarthritis could not be drawn, owing to the lack of long-term prospective studies available.
Efficacy of an Autologous Dermal Fibroblast Injection in Reducing the Retear Rate After Arthroscopic Rotator Cuff Repair: A Prospective Randomized Controlled Trial
Authors: Kim Young Kyu , Kim Yong Tae , Won Yoo-Sun , Jang Young Hoon , Hwang Sun Tae , Han Jikhyon , Jeon Saewha , Kim Sae Hoon , Oh Joo Han
Published: January 2025

Background:

Interest in biological augmentation for improving bone-tendon interface (BTI) healing after arthroscopic rotator cuff repair (ARCR) is growing. Dermal fibroblasts, known for collagen synthesis similar to tenocytes, have shown effectiveness in BTI healing in chronic rotator cuff tear (RCT) models in rabbits. However, no human clinical trials have been conducted.

Purpose:

To evaluate the clinical efficacy of autologous dermal fibroblasts (ADFs) for BTI healing after ARCR in patients with full-thickness RCTs >2 cm.

Study Design:

Randomized controlled trial; Level of evidence, 2.

Methods:

A total of 86 patients were prospectively enrolled and randomized into 2 groups: an additional ADF injection between the bone and tendon during ARCR (ADF group) or ARCR alone (control group). A skin biopsy from the buttock was performed to obtain ADFs, which were cultured for approximately 4 weeks before surgery. ARCR was standardized to the double-row suture bridge technique to reduce the heterogeneity in different repair methods. The primary variable for evaluating ADF efficacy was the retear rate using magnetic resonance imaging at 6 months postoperatively. Secondary variables included range of motion, the American Shoulder and Elbow Surgeons score, the Constant score, and the Simple Shoulder Test score at baseline and at 6 and 12 months postoperatively.

Results:

Overall, 13 patients dropped out because of a subscapularis tendon tear, loss to follow-up, or the withdrawal of consent (7 in the ADF group and 6 in the control group). The retear rate was significantly lower in the ADF group (5.6% [2/36]) than in the control group (24.3% [9/37]) ( P = .025). The American Shoulder and Elbow Surgeons, Constant, and Simple Shoulder Test scores showed significant improvement after surgery in both groups (all P values <.001). Functional scores and range of motion did not significantly differ between the 2 groups at 6 and 12 months (all P values >.05).

Conclusion:

ADF application into the BTI during ARCR significantly decreased the retear rate in patients with full-thickness RCTs >2 cm. Therefore, an ADF injection could be a promising biological supplement to enhance BTI healing in these patients. However, clinical outcomes showed no significant difference between the 2 groups at 6 months and 1 year postoperatively.
Bone Marrow Aspirate Concentrate Combined With an Appropriate Carrier Effectively Promotes Bone-Tendon Interface Healing in a Rabbit Model of Chronic Rotator Cuff Tear
Authors: Han Sheng Chen , Han Jian , Kim Young Kyu , Hyun Myung Jae , Jeong Hyeon Jang , Oh Joo Han
Published: January 2025

Background:

The efficacy of bone marrow aspirate concentrate (BMAC) in promoting bone-tendon interface (BTI) healing without any carriers remains a subject of debate.

Purpose:

To evaluate BMAC effects with different carriers on tendon regeneration in a rabbit model of chronic rotator cuff tear.

Study Design:

Controlled laboratory study.

Methods:

In vitro, the amount of growth factor and the differentiation potential of BMAC with different carriers (polydeoxyribonucleotide [PDRN] and atelocollagen [ATC]) were assessed. In vivo, 64 rabbits were randomly allocated into 4 groups. Different materials were injected into the repair site according to the allocated group: control, saline; BMAC, BMAC and saline; BMAC-PDRN, BMAC with PDRN; BMAC-ATC, BMAC with ATC (n = 16 in each). Genetic and histologic analyses were conducted at 4 and 12 weeks after repair, while biomechanical evaluations were performed at 12 weeks after repair.

Results:

In vitro, the degree of multilineage differentiation was much stronger using BMAC with ATC as compared with administration of BMAC alone or BMAC with PDRN ( P < .001). In vivo, the BMAC-ATC group had the highest levels of aggrecan expression, bone morphogenetic protein 2, and collagen type I alpha 1 among all groups (all P < .001) at 4 weeks after repair. Furthermore, the BMAC-ATC group showed collagen fiber continuity, denser collagen fibers, and more mature BTI as compared with the other groups (all P < .001) at 12 weeks after repair. Concurrently, the BMAC-ATC group also demonstrated significantly higher load-to-failure versus the remaining groups (all P < .001) at 12 weeks after repair.

Conclusion:

Local application of BMAC without appropriate carriers could not enhance BTI healing. However, BMAC with 2 different carriers effectively accelerated BTI healing, particularly in the ATC environment. Therefore, the combination of BMAC and ATC may act as a powerful biological agent to promote healing after rotator cuff repair in a chronic rotator cuff tear model using rabbits.

Clinical Relevance:

Local application of BMAC without appropriate carriers could not enhance BTI healing. However, the combination of BMAC and ATC may synergistically promote rotator cuff tendon healing.
“Is oral antioxidant (Vit C & E) helpful in minimizing shock wave induced renal damage? A study from a tertiary care Center from eastern India” A prospective study
Authors: Soni Praveen Kumar , Maiti Krishnendu , Sarkar Debansu
Published: January 2025

Introduction:

Extracorporeal shock wave lithotripsy (ESWL) causes trauma to the renal parenchyma. Due to the kidney injury, free radicals are generated, and an inflammatory process develops. Inflammatory markers like interleukin’s (IL), C-reactive protein (CRP), and procalcitonin (PCT) are released into the circulation. Antioxidants have the potential to mitigate the effects of the inflammatory process. Our objectives were the measurement of the effect of supplementation with Vit C and Vit E (antioxidants) and their effect on the reduction of CRP and procalcitonin and further kidney damage.

Methodology:

There were two groups with 100 patients each. Group A, receiving oral Vitamin E (400 mg twice a day) and oral Vitamin C (500 mg twice a day) beginning 3 days before the lithotripsy and continuing for up to 7 days after the lithotripsy (total of 10 days). Group B served as the control group. Serum levels of CRP and procalcitonin were measured on the day of lithotripsy, day 2, and day 10 post ESWL.

Results:

In Group B, CRP and PCT values are statistically significantly elevated as compared to Group A. In Group A, pre-ESWL, day 2 and day 10 CRP values are 1.23, 3.58, and 1.61. In Group B pre-ESWL, day 2 and day 10 CRP values are 1.38, 6.70, and 3.09 ( p value < 0.001 in day 2 and 10). In Group A, pre-ESWL, day 2 and day 10 PCT values are 0.41, 1.42, and 0.44. In Group B pre-ESWL, day 2 and day 10 PCT values are 0.36, 3.03, and 1.10 ( p value < 0.001 in day 2 and 10).

Conclusion:

The serum levels of the inflammatory marker for acute renal injury are decreased when vitamins C and E are taken orally, which can help to minimize kidney damage after lithotripsy for renal stone disease.
Tragic landscapes: TJ Clark and Gillian Rose on modernity and the future
Authors: Bunyard Tom
Published: January 2025

This essay places the work of the art historian TJ Clark in relation to the social and political philosophy of Gillian Rose. It develops an interpretation of the ideas that inform his art history, and of the ways in which they inform his advocacy of a ‘tragic’ approach to what he calls ‘Left’ politics. The latter approach is intended to avoid the dangers that Clark takes to be inherent in the Left's classical focus on shaping the social conditions of the future. The essay shows that Rose's philosophy is also sensitive to such concerns, and that it echoes aspects of Clark's position. In her work, however, this does not come at the cost of abandoning an orientation to the future. These points are developed via a discussion of the two writers’ respective conceptions of modernity, and via a consideration of their differing readings of two paintings by Nicolas Poussin.
Embracing Change Through Team Diversity: The Impact of Age Diversity on Civil Servants’ Perceptions of Organizational Change
Authors: Wynen Jan , Verlinden Stéphanie , Pieters Danika , Kleizen Bjorn , Verhoest Koen
Published: January 2025

This study explores the influence of age diversity within teams on civil servants’ perceptions of organizational change. Age diversity is examined through two dimensions: age variety, which refers to the range of different ages within a team, and age polarization, which denotes the extent to which age groups are segregated or clustered within a team. Individual perceptions of change are based on how civil servants evaluated a recent merger. While age polarization shows a significant effect—with less polarized teams exhibiting more positive perceptions of the merger—age variety does not demonstrate a notable impact. These results highlight that while age diversity is important, its impact is nuanced: simply having a range of ages is not sufficient, but reducing age polarization is crucial.
Effects of Online Professional Development on First-Grade Writing Instruction: Coaching plus Manual Improves Teachers’ Implementation, Confidence, and Students’ Writing Quality
Authors: Traga Philippakos Zoi A. , Rocconi Louis , Voggt Ashley
Published: January 2025

This mixed-methods study examined the effects of different models of online professional development (PD) on 21 US elementary teachers’ writing instruction, on the teachers’ confidence, and on students’ writing quality. Participants were first-grade teachers who were randomly assigned to one of three conditions: Coaching-plus-Manual (C+M), Manual (M), or Business-as-Usual (BAU). All teachers received online-PD but the C+M and the M conditions received PD on genre-based writing-strategy instruction. The M group taught using only the manual of that approach but the C+M also received coaching. Results found that C+M teachers increased the most in their writing confidence, and C+M students wrote papers of better quality at posttest compared to the M and BAU students.
Translanguaging Space Construction in Five Chinese EFL Learners’ Collaborative English-Language Culture-Introduction Videos: Patterns and Influential Factors
Authors: Fu Xuehua , Zhang Lawrence Jun
Published: January 2025

The study investigates how Chinese English-as-a-foreign-language (EFL) learners construct translanguaging space via multimodal orchestration in collaborative English-language YouTube videos introducing Chinese culture. By triangulating multimodal analysis of videos and students’ interview responses, the current research maps translanguaging space construction within and across modes and identifies four multimodal translanguaging space patterns. Meanwhile, learners’ understanding of modal affordances, their intents, their perceptions of the intended audience, and their experiences with relevant (multimodal) texts were found to influence their multimodal orchestration in translanguaging space construction. Digital multimodal composing (DMC) provides EFL learners with opportunities to draw upon their expanded multimodal repertoires, to combine multiple modes for meaning-making creatively, and to transcend the boundaries of languages and modalities critically. Pedagogical suggestions are provided regarding integrating DMC tasks into multilingual learning environments.

Adapted alternating treatment designs were used to evaluate and compare two computer-based phrase-reading interventions in four postsecondary students with an intellectual or developmental disability. Each intervention targeted eight unknown words from each student’s elective college class. For each word, interventions included three stimulus-response–stimulus-response learning trials, which prompted students to read a brief phrase containing an unknown word. During the single-phrase intervention, for each unknown word, three learning trials including the same phrase were presented. During the multiphrase intervention, three different phrases per unknown word were presented. Three generalization phrases were developed for each word. Both interventions increased students’ accurate reading of words embedded in generalization phrases and the entire generalization phrases, with the multiphrase intervention resulting in more rapid learning. Discussion focuses on future research designed to evaluate and enhance the effectiveness of phrase-reading interventions on generalized reading performance in students with disability.

Bystanders play a potentially important role in intervening in incidents of racism, but they often fail to act. Much research has focused on investigating facilitators and barriers to bystander behavior, but mainly in the context of sexual violence. There is a dearth of research in the context of racism, especially outside the English-speaking world. In this pilot study, we employed a qualitative approach to explore bystander facilitators and barriers in higher education students in Finland. Online participants ( N = 649) read two vignettes depicting a racist incident and wrote open-ended answers on factors that would facilitate and prevent intervention. We constructed six main themes using an inductive thematic analysis: (i) Perceived self-efficacy to intervene; (ii) Justification and moral reasoning; (iii) Clarity of the situation; (iv) Responsibility and permission to act; (v) Social relationships, support, and presence of others; and (vi) Consequences and impacts of action. We discuss the results with a reference to theories and literature, as well as the unique context of Finland.

Published: January 2025

The fashion industry is undertaking transformative changes driven by various digital technologies. However, these changes present challenges, ranging from employee resistance to slow organizational response to digital change, leading to a high rate of failure in digital transformations. Guided by the change readiness theory and Porter's Diamond Model, this study aims to conceptualize fashion digital readiness and systematically understand digital readiness in fashion business organizations, endeavoring to uncover the crucial drivers and enablers from a practical business perspective. Through a systematic review method, 64 peer-reviewed articles from Google Scholar reveals 5 clusters on the current state of literature, identifies 6 main drivers and 21 main enablers, and proposes the Fashion Digital Readiness—Drivers and Enablers (FDR-D, E) framework. The study expands on the advancements in change readiness theory into fashion digital readiness, provides insights into the propositions, theoretical and practical implications, and highlights further research avenues.
Microstructure generation of long fiber reinforced hybrid composites using the fused sequential addition and migration method
Authors: Lauff Celine , Schneider Matti , Böhlke Thomas
Published: January 2025

We present a fused sequential addition and migration (fSAM) algorithm to generate synthetic microstructures for long fiber reinforced hybrid composites. To incorporate the bending of long fibers, we model the fibers as polygonal chains and use an optimization framework to search for a non-overlapping fiber configuration with the desired properties. As microstructures of hybrid composites consist of materials with varying characteristics, e.g., different fiber orientation distributions or fiber volume fractions, the unit cell needs to be divided in subcells. Then, the objective function is required to account for the characteristics of the subcells individually. To ensure that the location of a fiber is restricted to its respective subcell, we apply box constraints during the optimization procedure. Depending on the materials and the manufacturing processes, the interfaces within hybrid composites show either strict separation or interlocking of the different materials. Hence, we enable selecting the box-constraint type to model the interface according to the desired composite. We provide a detailed discussion of the extensions of the original fSAM algorithm to generate hybrid composites, considering two alternative procedures to handle the box constraints during the optimization procedure. As the selection of the box-constraint type influences the synthetic microstructures, we investigate the shape of the interfacial areas and the computed effective stiffnesses. Last but not least, to validate the capability of the fSAM algorithm to generate representative microstructures, we compare the resulting mechanical behavior with experimental data.
Study on short-term mechanical properties of multi-reinforced steel-plastic composite pipe under internal pressure
Authors: Lv Jie , Li Yingjie , Zeng Li , Yuan Bei , Shi Jun
Published: January 2025

A multiple-reinforced steel-plastic composite pipe (MRSPCP) is a new type of composite pipe developed in China recent years. The MRSPCP is composed of high-density polyethylene (HDPE) matrix, steel-wire mesh, and steel strip. It is an improved version of the traditional structural wall pipe, and it is able to carry both external and internal pressures. Nowadays, it has been employed in many projects that require large diameter and high flow media transportation, such as water distribution systems, drainage systems, agricultural irrigation systems. As the MRSPCP is newly developed, its mechanical properties and failure mechanism are not clear, and its design method lacks theoretical basis, so this paper carries out the experimental, theoretical and simulated research to investigate the short-term mechanical properties of the MRSPCP. Firstly, uniaxial tensile tests are carried out to acquire the mechanical properties of the constituents. As the steel wire is curly and it is hard to get the stress-strain relationship directly, an inverse identification method was applied to determine the mechanical parameters of a bilinear model representing the steel-wire mechanical behavior. Moreover, short-term burst tests of the MRSPCP are carried out to assess its mechanical performance and provide data for the verification of the theoretical and simulated research. Secondly, a theoretical model is established to calculate the failure pressure by constructing force equilibrium relationship along the axial and hoop directions of the MRSPCP respectively, based on elastic mechanics. In the end, a finite element model of MRSPCP is established, considering the nonlinear mechanical property of the materials. Both the theoretical and the simulated results agrees well with the burst test result, with the relative error of only −13.18% and −4.41% respectively. As the finite element model not only provides more accurate result, but also it can demonstrate contour plots of different constituents inside the MRSPCP, the model is used to study the effects of the pipe thickness, composite strip winding angle and steel-wire diameter on the mechanical properties of MRSPCP. This study might be a guide for the design and safe application of the MRSPCP and similar composite pipes.

Published: January 2025

Background

Numerous deep leaning methods for low-dose computed technology (CT) image denoising have been proposed, achieving impressive results. However, issues such as loss of structure and edge information and low denoising efficiency still exist.

Objective

To improve image denoising quality, an enhanced multi-dimensional hybrid attention LDCT image denoising network based on edge detection is proposed in this paper.

Methods

In our network, we employ a trainable Sobel convolution to design an edge enhancement module and fuse an enhanced triplet attention network (ETAN) after each [Formula: see text] convolutional layer to extract richer features more comprehensively and suppress useless information. During the training process, we adopt a strategy that combines total variation loss (TVLoss) with mean squared error (MSE) loss to reduce high-frequency artifacts in image reconstruction and balance image denoising and detail preservation.

Results

Compared with other advanced algorithms (CT-former, REDCNN and EDCNN), our proposed model achieves the best PSNR and SSIM values in CT image of the abdomen, which are 34.8211and 0.9131, respectively.

Conclusion

Through comparative experiments with other related algorithms, it can be seen that the algorithm proposed in this article has achieved significant improvements in both subjective vision and objective indicators.
Proximal femur segmentation and quantification in dual-energy subtraction tomosynthesis: A novel approach to fracture risk assessment
Authors: Matsushima Akari , Chen Tai-Been , Kimura Koharu , Sato Mizuki , Hsu Shih-Yen , Okamoto Takahide
Published: January 2025

Background

Osteoporosis is a major public health concern, especially among older adults, due to its association with an increased risk of fractures, particularly in the proximal femur. These fractures severely impact mobility and quality of life, leading to significant economic and health burdens.

Objective

This study aims to enhance bone density assessment in the proximal femur by addressing the limitations of conventional dual-energy X-ray absorptiometry through the integration of tomosynthesis with dual-energy applications and advanced segmentation models.

Methods and Materials

The imaging capability of a radiography/fluoroscopy system with dual-energy subtraction was evaluated. Two phantoms were included in this study: a tomosynthesis phantom (PH-56) was used to measure the quality of the tomosynthesis images, and a torso phantom (PH-4) was used to obtain proximal femur images. Quantification of bone images was achieved by optimizing the energy subtraction (ene-sub) and scale factors to isolate bone pixel values while nullifying soft tissue pixel values. Both the faster region-based convolutional neural network (Faster R-CNN) and U-Net were used to segment the proximal femoral region. The performance of these models was then evaluated using the intersection-over-union (IoU) metric with a torso phantom to ensure controlled conditions.

Results

The optimal ene-sub-factor ranged between 1.19 and 1.20, and a scale factor of around 0.1 was found to be suitable for detailed bone image observation. Regarding segmentation performance, a VGG19-based Faster R-CNN model achieved the highest mean IoU, outperforming the U-Net model (0.865 vs. 0.515, respectively).

Conclusions

These findings suggest that the integration of tomosynthesis with dual-energy applications significantly enhances the accuracy of bone density measurements in the proximal femur, and that the Faster R-CNN model provides superior segmentation performance, thereby offering a promising tool for bone density and osteoporosis management. Future research should focus on refining these models and validating their clinical applicability to improve patient outcomes.
Leadership development programs in healthcare organizations: What they are and how to assemble them
Authors: Fortenberry John L.
Published: January 2025

In the highly competitive, perennially-changing healthcare industry, management prowess is vitally needed by those in positions of authority, but in isolation it is insufficient for delivering optimal results. Instead, management proficiencies must be complemented by leadership skills which amplify managerial efforts and outcomes. One avenue for building leadership acumen in healthcare organizations involves the establishment of leadership development programs. These programs generally assemble a range of opportunities permitting managers to learn about leadership and acquire associated proficiencies. Leadership development programs afford many benefits for healthcare providers, but in order to capitalize fully, thoughtful assembly is required. To shed light on this important topic, this article provides an overview of leadership development programs, noting a formal definition, stipulating associated benefits, and discussing options for assembly, all through the lens of Willis Knighton Health’s leadership development initiatives and experiences.
