Primary hepatic angiosarcoma: a systematic review
Authors: Rojas Santiago , Rey Chaves Carlos Eduardo , Robledo Sofía , Conde Danny , Sabogal Olarte Juan Carlos 
Published: January 2024

Background:
Hepatic angiosarcoma is a rare type of tumour. In adults, the diagnosis remains challenging as the clinical manifestations are generally nonspecific and are usually made too late when complications or metastases are already present, associated with a poor prognosis. Due to the lack of agreement regarding the optimal treatment approach, a comprehensive analysis of the evidence in the literature on the surgical and survival outcomes in terms of disease-free survival time (DFS) and overall survival (OS) for patients treated for primary hepatic angiosarcoma is needed.

Study design:
A systematic review of articles published in Pubmed, EMBASE, and Scopus, from 2000 to 2023 with the search terms hepatic angiosarcoma and liver resection or hepatectomy. Pooled individual data concerning the prognosis following various therapies was analyzed.

Results:
A total of 15 articles involving 886 patients were eligible for inclusion. The male population represents 66.2% (n=586) of the population, with a median age of 57 years (41–66). The median survival rate was 7 months. The median OS after surgical resection was 17.18 months (SD 12.6) vs. 3.72 months (SD 4.6) for patients treated without a surgical approach. The median DFS was 15.2 months (SD 11).

Conclusion:
Primary liver angiosarcoma remains a surgical challenge with a poor prognosis even with complete surgical resection and adjuvant therapy. Surgical management shows increased overall survival in comparison with non-surgical management. Early diagnosis could change the natural history of the disease. The literature available is scarce, and further studies are required to create standardized diagnostic and treatment protocols.

Authors: Uysal Halil Hakan , Yildirim Sahan Tezel , Keklicek Hilal , Anaforoglu Kulunkoglu Bahar 
Published: January 2024

Background:
It is obvious that educational activities were affected globally due to the pandemic.

Objective:
This study was planned to examine the effects of online education on undergraduate degree (UD) and associate degree (AD) Orthotics and Prosthesis education in the COVID-19 pandemic.

Study Design:
A crossectional online survey.

Method:
The Google Forms questionnaire was delivered to students of Orthotics and Prosthesis in the level of undergraduate degree and AD and academicians conducted in the study. Next, the participants were reviewed regarding their knowledge about devices used for online education and related technical problems. A 5-point Likert-type questionnaire with 18 questions that was developed specifically for this study was applied to examine their views on online education.

Results:
The study included 472 participants who had a mean age of 21.30 ± 0.22 years. Among the participants, 262 were AD students (55.5%). Approximately 82% of the participants were used their mobile phones for connection. The connection problems, and inappropriateness of online education in applied course, preference of online education for theoretical courses, insufficiency of digital course materials, failure to access education easily, insufficiency of online examinations for measurement and evaluation, and preference of homework over online education were stated by 79%, 88.3%, 41.9%, 54.5%, 70.1%, 41.7%, and 42.8% of the participants, respectively.

Conclusion:
Both academicians and students experienced connection problems, and applied courses were not suitable for online education. Motivation to attend the courses was low in online education, relevant workload increased, online examinations were not sufficient for measurement and evaluation, and studies were more unplanned. It is necessary to switch to formal education after the pandemic.

Published: January 2024

Objective
The present study aimed to evaluate the effectiveness of minimally invasive 980 nm laser-assisted lipolysis and skin tightening in lower eyelid blepharoplasty of Asian patients.

Methods
Patients with mild and moderate degree of eyebags underwent 980 nm laser-assisted lipolysis via lower eyelid stab incision between December 2017 and December 2019. Evaluation criteria was reviewed by photographs taken preoperatively and 6 months postoperatively in accordance with guidelines of Global Aesthetic Improvement Scale, the patient's perspective from the questionnaire with the perception of reduction in eyebags size, the average perception of improvement in skin tightening, and the patient overall satisfaction, all with a score of 1 to 5 (5 being the most noticeable and very satisfied) and complications such as dyspigmentation, hematoma, prolonged edema, skin bump and thermal burn were documented as well.

Results
A total of 178 cases with 137 women and 41 men (age range from 23 to 50 years) were included. Total energy of 1200 J to 2000 J was delivered to both eyebags at 6 to 10 W. They were followed up for at least 6 months. A total of 166 patients (93.26%) revealed an improvement in Global Aesthetic Improvement Scale, with the 12 patients (6.74%) complaint no change 6 month postoperatively. Perception of improvement in eye bag protrusion scored 4.39 ± 0.59, improvement in skin tightening scored 4.42 ± 0.58 and the overall patient's satisfaction scored 4.59 ± 0.53. The patients' average recovered swelling from 4.35 ± 2.3 days. There were 5 patients (2.8%) with dyspigmentation, 3 patients (1.69%) with prolonged edema and 2 patients (1.12%) with skin bump and none of the patients had thermal burn. All of them resolve after 6 months of follow up.

Conclusion
Patients with mild to moderate degree of eyebags who resist surgery are good candidates for laser-assisted lower eyelid blepharoplasty.
Comparison of Postoperative Complications in Patients Undergoing Limb Salvage Reconstructive Surgery Based on Estimated Prevalence of Preexisting Peripheral Arterial Disease
Authors: Pekcan Asli , Roohani Idean , Stoneburner Jacqueline , Boudiab Elizabeth , O'Brien Devon , Cordero Justin J. , Carey Joseph N. 
Published: January 2024

Background
Limb salvage after lower extremity (LE) trauma requires optimal blood flow for successful microsurgical reconstruction. Peripheral arterial disease (PAD) decreases LE perfusion, affecting wound healing. Patients who present with LE trauma may have undiagnosed PAD, particularly those with atherosclerotic risk factors. This study assesses outcomes after LE salvage in patients at risk for PAD.

Methods
This retrospective review evaluated patients who underwent LE reconstruction at a level 1 trauma center between 2007 and 2022. Patients with a nontraumatic mechanism of injury, missing postoperative records, and unspecified race were excluded. Demographics, flap characteristics, and postoperative complications were abstracted. The prevalence of LE PAD was calculated using a validated risk assessment tool.

Results
At our institution, 285 LE flaps performed on 254 patients were included in the study. Patients were categorized by prevalence of PAD, including 12 (4.7%) with high risk, 45 (17.7%) with intermediate risk, and 197 (77.6%) patients with low risk. The high-risk cohort had higher rates of partial flap necrosis (P = 0.037), flap loss (P = 0.006), and amputation (P < 0.001) compared with the low-risk group. Fewer high-risk patients achieved full ambulation compared with the low-risk (P = 0.005) cohort. Overall flap survival and limb salvage rates were 94.5% and 96.5%, respectively. Among the intermediate- and high-risk cohorts, only 50.9% of patients received a preoperative vascular assessment, and 3.8% received a vascular surgery consultation.

Conclusions
Peripheral arterial disease represents a reconstructive challenge to microvascular surgeons. Patients with high-risk for PAD had higher rates of partial flap necrosis, flap loss, and amputation. In the setting of trauma, emphasis should be placed on preoperative vascular assessment for patients at risk of having undiagnosed PAD. Prospective studies collecting ankle-brachial index assessments and/or angiography will help validate this study's findings.
Straintronics with single-layer
MoS2
: A quantum Monte Carlo study
Authors: Huang Y. , Manzoor M. , Brndiar J. , Milivojevic M. , Štich I. 
Published: January 2024

Using state-of-the-art quantum Monte Carlo (QMC) methods, we study straintronic properties of a single MoS2 monolayer. 2D MoS2 is a quintessential straintronic material for which many experiments have been performed. First, we determine the equilibrium atomic structure which is not known experimentally and is strictly needed to correctly determine the straintronic properties. That enables us to precisely analyze the quasiparticle band gaps for any applied biaxial strain, which we describe by a bivariate paraboloid function of lattice constant and internal structural parameter. Using the fixed-node QMC calculations fitted by analytical formulas, we localize the following excited state crossings between the direct, K→K, and indirect Γ→X and K→K/2 excitations. Based on this highly accurate many-body treatment, we predict a gauge factor of 136 meV/% for the K→K transition and a fairly narrow window of ≈2.8% from compressive to mildly tensile strains, accounting for only ≈0.3 eV band gap change maintaining the direct character of the gap. Consequently, we suggest that, compared to other 2D materials, such as phosphorene, there is only a limited straintronic tuneability in this material often studied for its straintronic properties. QMC results are compared to results of standard DFT modeling, which reveal insights into the corresponding inaccuracies and therefore open a window for educated use of rapid DFT approaches.

Thermodynamic limit of spin systems on random graphs
Authors: Searle Amy , Tindall Joseph 
Published: January 2024

We utilize the graphon—a continuous mathematical object which represents the limit of convergent sequences of dense graphs—to formulate a general, continuous description of quantum spin systems in thermal equilibrium when the average coordination number grows extensively in the system size. Specifically, we derive a closed set of coupled nonlinear Fredholm integral equations which governs the properties of the system. The graphon forms the kernel of these equations, and their solution yields exact expressions for the macroscopic observables in the system in the thermodynamic limit. We analyze these equations for both quantum and classical spin systems, recovering known results and providing analytical solutions for a range of more complex cases. We supplement this with controlled, finite-size numerical calculations using Monte Carlo and tensor network methods, showing their convergence towards our analytical results with increasing system size.

How knowledge sharing affects career adaptability: roles of knowledge depth, self-efficacy and reflective thinking
Authors: Xu Shiyong , Yu Jia , Zhou Jinyi 
Published: January 2024

PurposeDrawing on the social cognitive model of career self-management (CSM model) and deep learning theory, the authors' study aims to investigate the effect of knowledge sharing on career adaptability and explore how and when this effect occurs. The authors proposed a moderated sequential-mediation model linking knowledge sharing, knowledge depth, self-efficacy and career adaptability, moderated by reflective thinking.Design/methodology/approachThe authors used a field survey involving 611 employees working in different enterprises in China to test the authors' predictions. For supplementary validation, the authors conducted a scenario-based experiment with a distinct sample of 148 employees from Chinese enterprises. The authors used hierarchical regression analysis, ANOVA analysis and moderated sequential-mediation analysis to test the hypotheses.FindingsThe results indicated a positive effect of knowledge sharing on career adaptability, sequentially mediated through knowledge depth and self-efficacy. Additionally, reflective thinking strengthened the positive effect of knowledge sharing on knowledge depth and further moderated the sequential mediating effect.Originality/valuePrevious research has predominantly focused on the perspective that individuals act as “recipients” from the environment in developing career adaptability. Instead, the authors adopt a “giving” perspective by investigating the influence of knowledge sharing on career adaptability, which advances the existing knowledge on the predictors of career adaptability.
Human factors and cyber-security risks on the railway – the critical role played by signalling operations
Authors: Thron Eylem , Faily Shamal , Dogan Huseyin , Freer Martin 
Published: January 2024

Purpose
Railways are a well-known example of complex critical infrastructure, incorporating socio-technical systems with humans such as drivers, signallers, maintainers and passengers at the core. The technological evolution including interconnectedness and new ways of interaction lead to new security and safety risks that can be realised, both in terms of human error, and malicious and non-malicious behaviour. This study aims to identify the human factors (HF) and cyber-security risks relating to the role of signallers on the railways and explores strategies for the improvement of “Digital Resilience” – for the concept of a resilient railway.

Design/methodology/approach
Overall, 26 interviews were conducted with 21 participants from industry and academia.

Findings
The results showed that due to increased automation, both cyber-related threats and human error can impact signallers’ day-to-day operations – directly or indirectly (e.g. workload and safety-critical communications) – which could disrupt the railway services and potentially lead to safety-related catastrophic consequences. This study identifies cyber-related problems, including external threats; engineers not considering the human element in designs when specifying security controls; lack of security awareness among the rail industry; training gaps; organisational issues; and many unknown “unknowns”.

Originality/value
The authors discuss socio-technical principles through a hexagonal socio-technical framework and training needs analysis to mitigate against cyber-security issues and identify the predictive training needs of the signallers. This is supported by a systematic approach which considers both, safety and security factors, rather than waiting to learn from a cyber-attack retrospectively.
Forestry offsets under China’s certificated emission reduction (CCER) for carbon neutrality: regulatory gaps and the ways forward
Authors: Xu Shengqing 
Published: January 2024

Purpose
As a typical nature-based solution to climate change, forestry carbon sinks are vital to achieving carbon neutrality in China. However, regulations in China are insufficient to promote the development of carbon offset projects in forestry. This study aims to identify the regulatory obstacles impeding the development of forestry offsets under China’s certified emission reduction (CCER) and explore ways to improve the regulatory system.

Design/methodology/approach
This study conducts a qualitative analysis using a normative legal research method. This study conducted a synthetic review of national and local regulatory documents to gain insights into the regulatory landscape of forestry offsets in China. The main contents and characteristics of these documents are illustrated. Furthermore, related secondary literature was reviewed to gain further insight into forestry offset regulations and to identify significant gaps in China’s CCER regulation.

Findings
Forestry offset regulations under the CCER are characterized by fragmentation and a relatively lower legally binding force. There is no systematic institutional arrangement for forestry offset development, impeding market expectations and increasing transaction costs. The main challenges in China’s regulation of forestry carbon sinks include entitlement ambiguity, complicated rules for registration and verification, a lack of mechanisms for incentives, risk prevention and biodiversity protection.

Originality/value
Forestry carbon sinks’ multiple environmental and social values necessitate their effective development and utilization. This study assessed forestry offset regulations in China and proposed corresponding institutional arrangements to improve forestry carbon sink regulations under the CCER.

The effects of polarisation on trust in government: evidence from Ethiopia
Authors: Gebrihet Hafte Gebreselassie , Mwale Martin Limbikani 
Published: January 2024

Purpose
The purpose of this study is to examine the effect of polarisation on trust in government.

Design/methodology/approach
The authors use the ordered probit technique to model trust as a function of polarisation and various control variables. The authors apply the instrumental variables approach to address potential endogeneity in polarisation, using ethnic diversity as an instrument.

Findings
The results reveal that an increase in polarisation reduces trust in central government. However, trust in local government is non-responsive to this polarisation. The estimations controlled for government performance, and the authors found a positive association between government performance and trust in government, which, however, does not alter the relationship between polarisation and trust in government.

Practical implications
In ethnically polarised nations, policymakers should consider decentralisation measures. This can help sustain trust and development support, particularly in regions where citizens prioritise ethnicity over nationality.

Social implications
The social implications of this research underscore the importance of promoting trust in government to foster social cohesion and stability, particularly in ethnically diverse societies.

Originality/value
The authors find that increased ethnic polarisation reduces trust in the central government, particularly among those prioritising their ethnicity over nationality. This adds a non-performance dimension to government trust literature, suggesting that policies focusing solely on performance may yield limited results. The research extends beyond central government trust to include local governments. Unlike central government, local government trust remains tied to performance attributes unaffected by polarisation. Hence, investing resources through local governments is a viable strategy for enhancing citizen support while mitigating polarisation’s adverse effects.
Strengths use support and knowledge sharing: mediating roles of work engagement and knowledge self-efficacy
Authors: Matsuo Makoto 
Published: January 2024

Purpose
This study aims to examine the influence of perceived supervisor support (PSS) for strengths use on knowledge sharing (KS) intentions, mediated through work engagement and knowledge self-efficacy, based on the job demand-resources theory and the broaden and build theory.

Design/methodology/approach
Structural equation modeling and bootstrap analyses were performed to examine the research model using data derived from a two-wave questionnaire survey of 162 employees from five health-care organizations.

Findings
The results indicate that PSS for strengths use promoted KS intentions fully mediated through work engagement and subsequently through knowledge self-efficacy. However, there was no direct relationship between PSS for strengths use and KS intention.

Originality/value
The contribution of this research to the literature on KS is to find the effectiveness of a strengths-based approach in promoting KS intentions across boundaries and identifying mediating factors that link PSS for strengths use to KS intentions.
