Application of Preexpanded Free Flaps Based on Thoracic Branch of Supraclavicular Artery for Facial Scar Treatment
Authors: Pei Jiaomiao , Zhang Juan , Liu Chaohua , Li Yang , Song Baoqiang 
Published: April 2023

Background:
As an exposure region, the face is susceptible to burn injuries, which often lead to physical and psychological problems. For facial scar reconstruction, the subclavicular region has the advantages of matched color, similar texture, and thin and pliable tissue supply. The island or pedicled subclavicular flap, which is nourished by the thoracic branch of supraclavicular artery (TBSA) had been reported to cover cervical facial defects and achieved good outcomes. However, the main restriction is the limitation of the pedicle length. Therefore, the authors applied preexpanded TBSA free flap transplantation for treatments of upper and contralateral facial scars to overcome the pedicle limitation.

Methods:
Three patients were treated with preexpanded TBSA flaps to repair the facial defects after scar resections. Two of them were combined with forearm or deltopectoral flaps according to different purposes. The patients were followed up for 2 to 7 years. The clinical data and surgical techniques were recorded and analyzed. The scars were scored by Vancouver Scar Scale.

Results:
Two of the TBSA flaps survived well without complication. Partial flap necrosis in the distal end was healed by dressing changes, and mild contracture in the left medial canthus was corrected by Z plasty in case 1. The scars around transferred flaps and donor sites were scored 3 to 4 by Vancouver Scar Scale. The patients were satisfied with the outcomes. All the donor sites were closed primarily.

Conclusion:
A preexpanded TBSA-free flap could overcome the restriction of pedicle length for reconstruction procedures. The method is a feasible alternative of thoracic flaps to repair facial defects beyond pedicle limitation.

Published: April 2023

Objective:
The objective of this study was to compare endovascular aortic aneurysm repair (EVAR) versus open aortic repair (OAR) on mortality and reintervention after ruptured infrarenal abdominal aortic aneurysm (rAAA) repair in the Vascular Quality Initiative (VQI).

Background:
The optimal treatment modality for rAAA remains debated, with little data on long-term comparisons.

Methods:
VQI rAAA repairs (2004–2018) were matched with Medicare claims (VQI-VISION). Primary outcomes were in-hospital and long-term mortality. Secondary outcome was reintervention. Inverse probability weighting was used to adjust for treatment selection, and Cox Proportional Hazards models and negative binomial regressions were used for analysis. Landmark analysis was performed among patients surviving hospital discharge.

Results:
Among 1885 VQI/Medicare rAAA patients, 790 underwent OAR, and 1095 underwent EVAR. Median age was 76 years; 73% were male. Inverse probability weighting produced comparable groups. In-hospital mortality was lower after EVAR versus OAR (21% vs 37%, odds ratio: 0.52, 95% CI, 0.4–0.7). One-year mortality rates were lower for EVAR versus OAR [hazard ratio (HR) 0.74, 95% CI, 0.6–0.9], but not statistically different after 1 year (HR: 0.95, 95% CI, 0.8–1.2). This implies additional benefits to EVAR in the short term. Reintervention rates were higher after EVAR than OAR at 2 and 5 years (rate ratio: 1.79 95% CI, 1.2–2.7 and rate ratio:2.03 95% CI, 1.4–3.0), but not within the first year. Reintervention was associated with higher mortality risk for both OAR (HR: 1.66 95% CI, 1.1–2.5) and EVAR (HR: 2.14 95% CI, 1.6–2.9). Long-term mortality was similar between repair types (HR: 0.99, 95% CI, 0.8–1.2).

Conclusions:
Within VQI/Medicare patients undergoing rAAA repair, the perioperative mortality rate favors EVAR but equalizes after 1 year. Reinterventions were more common after EVAR and were associated with higher mortality regardless of treatment.
Five-year Comorbidity Outcomes in Laparoscopic Vertical Sleeve Gastrectomy (LVSG) and Laparoscopic Roux-en-Y Gastric Bypass (LRYGB): A Systematic Review and Meta-analysis of Randomized Controlled Trials
Authors: Osland Emma J. , Yunus Rossita M. , Khan Shahjahan , Memon Muhammed Ashraf 
Published: April 2023

Background:Laparoscopic vertical sleeve gastrectomy (LVSG) is now the most commonly performed bariatric procedure; however, it remains to be elucidated if it delivers equivalent long-term comorbid disease resolution outcomes similar to the longer established laparoscopic Roux-en-Y gastric bypass (LRYGB). We undertook a systematic review and meta-analysis of randomized controlled trials (RCTs) to investigate the comparative 5-year outcomes of both procedures.Methods:Electronic databases (Pubmed, EMBASE, CINAHL) were searched for RCTs conducted in adults (>18y) that compared the 5-year- outcomes of LVSG to LRYGB and described comorbidity outcomes were included. Where data allowed, effect sizes were calculated using the Hartung-Knapp-Sidik-Jonkman estimation method for random effects model. Presence of bias was assessed with Cochrane Risk of Bias 2.0 and funnel plots, and certainty of evidence evaluated by GRADE. The study prospectively registered with PROSPERO (CRD42018112054).Results:Three RCTs (LVSG=254, LRYGB=255) met inclusion criteria and reported on chronic disease outcomes. Improvement and/or resolution of hypertension favoured LRYGB (odds ratio 0.49, 95% CI 0.29, 0.84;P=0.03). Trends favoring LRYGB were seen for type 2 diabetes and dysplidemia, and LVSG for sleep apnea and back/joint conditions (P>0.05). The certainty of evidence associated with each assessed outcome ranged from low to very low, in the setting of ‘some’ to ‘high’ bias assessed as being present.Conclusion:Both LRYGB and LVSG are effective in providing long-term improvements in commonly experienced obesity-related comorbidities; however, the limited certainty of the evidence does not allow for strong clinical conclusions to be made at this time regarding benefit of one procedure over the other.
Efficacy of Laparoscopic Iliopubic Tract Repair Plus Transabdominal Preperitoneal Hernioplasty for Treating Inguinal Hernia After Robot-assisted Radical Prostatectomy
Authors: Lee Sung Ryul 
Published: April 2023

Background:
Robot-assisted radical prostatectomy (RARP) is a risk factor for inguinal hernia (IH). Furthermore, in patients who have undergone RARP, the fibrotic scar tissue in the RARP area limits preperitoneal dissection. This study aimed to evaluate the efficacy of performing laparoscopic iliopubic tract repair (IPTR) in addition to transabdominal preperitoneal hernioplasty (TAPPH) to treat IH after RARP.

Patients and Methods:
A total of 80 patients with an IH after RARP were treated with TAPPH from January 2013 to October 2020 and were included in this retrospective study. Patients who underwent conventional TAPPH were categorized as the TAPPH group (25 patients with 29 hernias), whereas those who underwent TAPPH with IPTR were categorized as the TAPPH + IPTR group (55 patients with 63 hernias). The IPTR comprised suture fixation of the transversus abdominis aponeurotic arch to the iliopubic tract.

Results:
All patients had indirect IH. The incidence of intraoperative complications was significantly higher in the TAPPH group than in the TAPPH + IPTR group [13.8% (4/29) vs 0.0% (0/63), P = 0.011]. The average operative time was also significantly shorter in the TAPPH + IPTR group than in the TAPPH group (P < 0.001). There were no differences between the two groups in the duration of hospitalization, recurrence rate, and pain severity.

Conclusions:
The addition of laparoscopic IPTR to TAPPH for treating IH after RARP is safe and is associated with a minimal risk of intraoperative complications and a short operative time.
Identification and assessment of risks related to digitalization in Indian construction: a quantitative approach
Authors: Bajpai Avirag , Misra Subhas Chandra , Kim Dong-Young 
Published: April 2023

PurposeThe purpose of this research article is to investigate the critical risk factors associated with the digitalization impact on the Indian construction industry, as these firm plans to implement digitalization in order to improve their construction management processes.Design/methodology/approachIn this research article, risk factors and dimensions are taken from diverse industries and validated in the construction domain by industry and academic experts. Further, multi-criteria decision-making techniques are employed to assess the Indian construction sector scenario quantitatively. The interrelationship and weightage of risk factors and dimensions are determined by the Fuzzy Decision-making Trial and Evaluation Laboratory Analytic Network Process (DANP) method. However, the method Grey Technique for the Order of Prioritization by Similarity to Ideal Solution (TOPSIS) is used to determine the ranking of each risk factor.FindingsThis study finds 14 critical risk factors along with four risk dimensions. Operational and financial dimensions are significant risk dimensions. Whereas the threat of high outlay and low yield is a significant risk factor in construction. Besides that, the interrelationship among risk factors, the weightage of each factor and the ranking of critical risk factors are also identified.Research limitations/implicationsThis research article uses Fuzzy DANP and Grey TOPSIS techniques as exploratory research methods with a limited group of construction professionals from a leading Indian construction firm. Furthermore, comprehensive confirmatory research can also be performed with a large group of construction experts using advanced analytical techniques to validate the ranking of critical risk factors.Practical implicationsThe findings of this study provide insight into the knowledge of construction firms by emphasizing significant risk factors related to digitalization in construction operations. Another finding of this study shows that the risks associated with digitalization in construction are similar to those in manufacturing, where high outlay and low yield hold a significant role in the transformation process.Originality/valueThe research is unique since there have only been limited studies in the Indian construction scenario to analyze the significant risks associated with digitalization. Furthermore, this study demonstrates that the combination of Fuzzy DANP and Grey TOPSIS techniques may be used successfully to prioritize risks in construction digitalization, which is still in its early phases.
Improved methods for stator end winding leakage inductance calculation
Authors: Kostro Grzegorz , Michna Michal , Kutt Filip , Ryndzionek Roland 
Published: April 2023

Purpose
Calculating the stator end-winding leakage inductance, taking into account the rotor, is difficult due to the irregular shape of the end-winding. The end-winding leakage may distribute at the end of the active part and the fringing flux of the air gap. The fringing flux belongs to the main flux but goes into the end-winding region. Then, not all the magnetic flux occurring in the end region is the end-winding leakage flux. The purpose of this paper was to find a method to accurately separate the leakage from the total flux, taking into account the rotor.

Design/methodology/approach
In this paper, two methods based on energy calculation are presented. Both methods require the assumption that the machine is symmetrical. The first method depends on the total leakage inductance and the machine’s active region length. The second method is based on the energy stored in the end region of the machine. In this case, removing the energy produced by the fringing flux of the air gap is necessary. The model should have a volume-closing fringing flux to remove the part of energy belonging to the end of the air gap.

Findings
The method presented in the paper does not require rotor removal. The values of the end-winding leakage inductance computed based on the proposed method were compared with values computed using the method with the removed rotor. The computations show that the proposed method is closest to the results from the method presented in the literature. Results obtained in the first method present that rotor influence on the value of end-winding leakage inductance exists. The model of the stator end-winding described in the paper is general. Therefore, the proposed methods are suitable for calculating the end-winding leakage inductance of other electric machines.

Originality/value
The method presented in the paper considers the rotor in end-winding leakage inductance calculation. It is not necessary to remove the rotor as in the similar method presented in the literature. The authors elaborated a parametric model with a volume-closing fringing flux to remove the part of energy belonging to the end of the air gap. The authors also elaborated their 3D model of the machine winding for calculations in Opera 3D.
Measuring long-run housing affordability for Malaysian millennial households: a geospatial and income distribution analysis
Authors: Rangel Gary John , Ng. Jason Wei Jian , Murugasu Thangarajah Thiyagarajan , Poon Wai Ching 
Published: April 2023

Purpose
The purpose of this study is to use a lifetime income measure to evaluate the long-run housing affordability for an understudied cohort of households in the literature – the millennials. The authors do this in the context of Malaysia, measuring long-run affordability for four housing types across geographic locations and income distributions.

Design/methodology/approach
This study calculates a long-run housing affordability index (HAI) using data on house prices and household incomes. Essentially a ratio of predicted lifetime incomes to house prices, the HAI is computed for four common housing types in Malaysia from 2005 to 2016 and for six states in the country. The HAI is also compared across four income percentiles.

Findings
The analysis reveals varying patterns of housing affordability among different states in Malaysia. Housing affordability has declined since 2010, with most housing types being unaffordable for millennial-led households with the lowest income. Housing is most affordable for those in the highest income bracket, although even here, there are pockets of unaffordable housing as well.

Practical implications
Based on the findings, this study proposes three targeted interventions to improve housing affordability for Malaysian millennials.

Originality/value
This study fills a gap in the literature by examining the long-run housing affordability of Malaysian millennial-led households based on both geographic location and income distribution. The millennial population is understudied in the housing affordability literature, making this study a valuable contribution to the field.
On impersonal justice: libraries' neutrality as an act of change
Authors: Foderaro Antonella 
Published: April 2023

PurposeThis study introduces Simone Weil's impersonal justice concept and its relevance to libraries' identity and role in societies. The article presents the constituents of impersonal justice and a theoretical justification for the coexistence of neutrality with libraries' commitment to social causes.Design/methodology/approachConceptual analysis of 3 Weil's works, 13 scientific articles and 12 libraries' official documents was applied, looking at relevant concepts and findings, contexts of use, arguments and types of authority.FindingsFive constituents of impersonal justice were found: universality, concreteness, unicity, inviolability and inappropriability. Impersonal justice, based on the inviolable value of each individual and the universal expectation of good, allows for a more accurate definition of social justice. Besides, it justifies libraries' commitment to climate change, migrants and Black lives matter, among other causes.Originality/valueIn contrast to previous works, this paper focuses on clarifying concepts by applying conceptual analysis to Weil's works, Library and Information Science (LIS) sources in scientific and normative contexts. Additionally, the analysis of arguments and types of authority for justifying claims pro and against neutrality allows the reconstruction of the argumentative discourse beyond the examined sources.
From seedlings to ships: supply chain and production management in the Venice Arsenale, 1400–1800
Authors: Wilson James M. , Favotto Alvise 
Published: April 2023

Purpose
The Arsenale was the largest medieval industrial enterprise, famous for its assembly line. Management faced extreme variations between peace-time and war-time demands. Satisfying these unpredictable and sudden demands for a large, complex product with a multiple years–long production cycle was challenging. The purpose of this study is to analyze the Arsenale’s operations and supply chain arrangements, and to identify and assess their management policies. We also track its development and investigate its influence on other countries.

Design/methodology/approach
The research methodology used is archival research with content analysis of text and graphic representations of production processes.

Findings
These reveal that Venice’s supply chain management evolved from simply exploiting woodlands as needs arose, to a managed forest with planned planting, cultivation and harvesting, ending with the active modification of growing trees so their natural growth was artificially shaped to satisfy production requirements. Instead of fabricating components in their factory, the Venetians formed them by shaping the trees while they were still growing. These arboriculture techniques then provided a planned and regular supply of high-quality components that purely natural processes provided only randomly.

Research limitations/implications
There may be undiscovered archival documents despite the authors’ best efforts. The development of this historic supply chain reflects modern managerial concerns.

Practical implications
Modern restorations of historic ships and buildings use some of the fabrication methods identified, although the more intensive techniques would require higher volume production.

Social implications
This reveals historical forestry practices emphasised long-term needs and sustainable use.

Originality/value
To the best of the authors’ knowledge, this is a unique long-term investigation of an integrated production system and considers its influence on Iberian, French, British and American forestry and ship building. The close integration of production requirements with forestry practices was a novel finding.
Empowering middle managers to free their strategic capabilities
Authors: Letierce Clara , Mills Colleen , Arnaud Nicolas 
Published: April 2023

PurposeThis article aims to better understand how empowered middle manager engage in change translation? Relying on the notions of building and dwelling strategizing, the authors analyze the micro-practices of middle managers during organizational change, when middle managers are freed from time-consuming administrative activities.Design/methodology/approachThis empirical study relies on a qualitative embedded case study approach that involves comparing two banking units belonging to a large French bank. The qualitative data were collected from three different sources: exploratory and semi-structured interviews, observations and secondary data. The coding analysis enables to distinguish middle managers' dwelling and building strategizing during organizational change.FindingsThe study’s findings show how managers translate organizational change relying on both building and dwelling strategizing. By doing so, managers enable to adapt the prescribed strategy to local circumstances and foster front-line empowerment.Research limitations/implicationsEven though the findings are based on the analysis of a single organization, the authors provide several theoretical insights. First, the authors contribute to the recent academic debate in strategy-as-practice literature by showing the recursive relation between building and dwelling strategizing. The authors also shed a new light on middle managers' strategizing by emphasizing the idea that middle managers are not only passive change “translators” but that middle managers enact a real agency in the organizational change process.Practical implicationsFrom a managerial perspective, the study’s findings enable to enlight what empowering middle managers means in practice. Indeed, the authors show clear empirical illustrations of how middle managers can be empowered by both organizational structure and top-management support. The results also reveal how empowering middle managers enable to empower their team by three different activities: (1) federate the team spirit to facilitate collaboration; (2) develop employees' capabilities and (3) adjust managers' activity according to employees' needs.Originality/valueWhile multiple current new ways of organizing encourage to transform organizations from inefficient bureaucracies into flatter and more dynamic project-based teams, calling into question the importance of middle managers' strategic role, this study provides an original case study of an organization that chose to run against the tide and created an additional middle management level.
Effectiveness of MOOCs on learning efficiency of students: a perception study
Authors: N. Abhishek , Kulal Abhinandan , M.S. Divyashree , Dinesh Sahana 
Published: April 2023

PurposeThe study is aimed at analyzing the perceptions of students and teachers regarding the effectiveness of massive open online courses (MOOCs) on learning efficiency of students and also evaluating MOOCs as an ideal tool for designing a blended model for education.Design/methodology/approachThe analysis was carried out by using the data gathered from the students as well as teachers of University of Mysore, Karnataka, India. Two separate sets of questionnaires were developed for both the categories of respondents. Also, the respondents were required to have prior experience in MOOCs. Further, the collected data was analyzed using statistical package for social sciences (SPSS).FindingsThe study showed that MOOCs have a more positive influence on learning efficiency, as opined by both teachers and students. Negative views such as cheating during the assessment, lack of individual attention to students and low teacher-student ratio were also observed.Practical implicationsMany educational institutions view that the MOOCs do not influence learning efficiency and also do not support in achieving their vision. However, this study provides evidence that MOOCs are positively influencing the learning efficiency and also can be employed in a blended model of education so as to promote collaborative learning.Originality/valueTechnology is playing a pivotal role in all fields of life and the education sector is not an exception. It can be rightly said that the technology-based education models such as MOOCs are the need of the hour. This study may help higher education institutions to adopt MOOCs as part of their blended model of education, and, if already adopted, the outcome of the present study will help them to improve the effectiveness of the MOOCs they are offering.
