Authors: Erguibi Driss , Kamal Khadija , Eddaoudi Yassine , Hajri Amal , Boufettal Rachid , Rifki El Jai Saad , Chehab Farid 
Published: March 2023

Introduction:
It is a great challenge to distinguish the parietal inflammation, centered on the foreign body that pierced the digestive tract and remained in the wall before surgery, because of its atypical clinical nature. Ingestion of foreign bodies is not uncommon. Fish bones are particularly notorious culprits; however, most will pass through the gastrointestinal tract uneventfully.

Patients and Methods:
The authors report a case of a patient who presented with periumbilical abdominal pain and a computed tomography (CT) scan that revealed the presence of periumbilical fat infiltration on a foreign body admitted on the Department of Digestive Cancer Surgery and Liver Transplantation, Casablanca, Morocco. An exploratory laparotomy revealed a parietal mass centered by a fish bone.

Results:
Accidental ingestion of foreign bodies is common in clinical practice. However, perforation of the intestine by a foreign body is less common because the majority of foreign bodies pass without incident into the feces and only 1% of them (the sharpest and most elongated objects) will perforate the gastrointestinal tract, usually at the level of the ileum.
CT, especially multidetector CT, is considered the method of choice for preoperative diagnoses of ingested foreign bodies and their complications due to its high-quality multiplanar capabilities and high resolution.
Foreign body ingestion usually goes unnoticed, but the complications of this incident can be severe.

Conclusion:
This case report highlights the fact that intestinal perforation caused by an ingested foreign body is a difficult diagnosis that should always be suspected in an attack of abdominal pain. Frequently, the clinical diagnosis is difficult, and recourse to imaging is sometimes necessary. Most of the time, the treatment is only surgical.
An Easy Way to Harvest Super-thin SCIP flap with Long Pedicle: Reappraisal of the Inferolateral Branches of SCIA
Authors: Zhang Yuwei , Zeng Ang 
Published: March 2023

Despite being the first free flap used in reconstructive surgery in 1973 1, the groin flap slowly fell out of fashion because of its short pedicle length, small vessel diameter, variable vascular anatomy, and bulkiness. In 2004, Dr. Koshima revived the groin flap by applying the concept of perforators and proposed the superior iliac artery perforator (SCIP) flap, which he used successfully to reconstruct limb defects 2. As a workhorse flap, the SCIP flap can be used to reconstruct various body regions 3-15. However, it is still challenging to harvest super-thin SCIP flaps with long pedicles.
Over the years, we have found perforators consistently exist inferolateral to the deep branch of SCIA forming an F configuration with the main branch. The F configuration of the perforators have reliable anatomy and extend directly into the dermal plexus. In this article, we present the anatomy of these perforators of SCIA with F configurations and describe the flap design based on them.
Identification of drug compounds for capsular contracture based on text mining and deep learning
Authors: Lu Yeheng , Chen Zhiwei , Pan Yuyan , Qi Fazhi 
Published: March 2023

Background:
Capsular contracture is a common and unpredictable complication after breast implant placement. Currently, the pathogenesis of capsular contracture is unclear and the effectiveness of non-surgical treatment is still doubtful. Our study aimed to investigate new drug therapies for capsular contracture by using computational methods.

Methods:
Genes related to capsular contracture were identified by text mining and GeneCodis. Then the candidate key genes were selected through protein-protein interaction analysis in STRING and Cytoscape. Drugs targeting the candidate genes with relation to capsular contracture were screened out in Pharmaprojects. Based on the drug-target interaction analysis by DeepPurpose, candidate drugs with highest predicted binding affinity were obtained eventually.

Results:
Our study identified 55 genes related to capsular contracture. Gene set enrichment analysis and protein-protein interaction analysis generated 8 candidate genes. 100 drugs targeting the candidate genes were selected. 7 candidate drugs with highest predicted binding affinity were determined by DeepPurpose, including tumor necrosis factor alpha (TNF-α) antagonist, estrogen receptor (ESR) agonist, insulin like growth factor 1 (IGF-1) receptor tyrosine kinase inhibitor and matrix metallopeptidase 1 (MMP1) inhibitor.

Conclusion:
Text mining and DeepPurpose can be used as a promising tool for drug discovery in exploring non-surgical treatment to capsular contracture.
Baseline Characteristics and Clinical Presentation of Biopsy-Proven Giant Cell Arteritis in White Compared with Black Patients
Authors: Sun Emily , Li Ximin , Gruener Anna M. , Chang Jessica R. , Henderson Amanda D. , Carey Andrew R. 
Published: March 2023

Background:
Giant cell arteritis (GCA) is the most prevalent systemic vasculitis in the elderly and can lead to permanent vision loss if left untreated. Most earlier studies have evaluated GCA in primarily white populations, and GCA was traditionally thought to occur at nearly negligible frequency in black populations. Our previous study showed that GCA may occur at similar rates in white and black patients, but little is known about the presentation of GCA in black patients. The purpose of this study is to examine baseline presentation of biopsy-proven GCA (BP-GCA) in a tertiary care center–based population with a sizeable proportion of black patients.

Methods:
Retrospective study from a single academic institution of a previously described cohort of BP-GCA. Presenting symptoms, laboratory findings, and GCA Calculator Risk score were compared in black and white patients with BP-GCA.

Results:
Among 85 patients with biopsy-proven GCA, 71 (84%) were white and 12 (14%) were black. White patients had higher rates of elevated platelet count (34% vs 0%, P = 0.04), whereas black patients had higher rates of diabetes mellitus (67% vs 12%, P < 0.001). There were no statistically significant differences in age, gender, biopsy classification (active vs healed arteritis), cranial symptoms, visual symptoms/ophthalmic findings, rates of abnormal erythrocyte sedimentation rate or C-reactive protein, unintentional weight loss, polymyalgia rheumatica, or GCA risk calculator score.

Conclusions:
Presenting features of GCA were similar between white and black patients in our cohort, except for rates of abnormal platelet level and diabetes. Physicians should feel comfortable relying on the usual clinical features for the diagnosis of GCA independent of race.

Three strains (H4-D09T, S2-D11 and S9-F39) of a member of the genus

Paracoccus

attributed to a novel species were isolated from topsoil of temperate grasslands. The genome sequence of the type strain H4-D09T exhibited a complete set of genes required for denitrification as well as methylotrophy. The genome of H4-D09T included genes for two alternative pathways of formaldehyde oxidation. Besides the genes for the canonical glutathione (GSH)-dependent formaldehyde oxidation pathway, all genes for the tetrahydrofolate–formaldehyde oxidation pathway were identified. The strain has the potential to utilize methanol and/or methylamine as a single carbon source as evidenced by the presence of methanol dehydrogenase (mxaFI) and methylamine dehydrogenase (mau) genes. Apart from dissimilatory denitrification genes (narA, nirS, norBC and nosZ), genes for assimilatory nitrate (nasA) and nitrite reductases (nirBD) were also identified. The results of phylogenetic analysis based on 16S rRNA genes coupled with riboprinting revealed that all three strains represented the same species of genus

Paracoccus

. Core genome phylogeny of the type strain H4-D09T indicated that

Paracoccus thiocyanatus

and

Paracoccus denitrificans

are the closest phylogenetic neighbours. The average nucleotide index (ANI) and digital DNA–DNA hybridization (dDDH) with the closest phylogenetic neighbours revealed genetic differences at the species level, which were further substantiated by differences in several physiological characteristics. The major respiratory quinone is Q-10, and the predominant cellular fatty acids are C18 : 1ω7c, C19 : 0cyclo ω7c, and C16 : 0, which correspond to those detected in other members of the genus. The polar lipid profile consists of a diphosphatidylglycerol (DPG), phosphatidylethanolamine (PE), phosphatidylglycerol (PG), phosphatidylcholine (PC), aminolipid (AL), glycolipid (GL) and an unidentified lipid (L).
On the basis of our results, we concluded that the investigated isolates represent a novel species of the genus

Paracoccus

, for which the name Paracoccus methylovorus sp. nov. (type strain H4-D09T=LMG 31941T= DSM 111585T) is proposed.
A prediction model of users' attention transfer in the context of multitopic competition
Authors: An Lu , Shen Yan , Li Gang , Yu Chuanming 
Published: March 2023

PurposeMultiple topics often exist on social media platforms that compete for users' attention. To explore how users’ attention transfers in the context of multitopic competition can help us understand the development pattern of the public attention.Design/methodology/approachThis study proposes the prediction model for the attention transfer behavior of social media users in the context of multitopic competition and reveals the important influencing factors of users' attention transfer. Microblogging features are selected from the dimensions of users, time, topics and competitiveness. The microblogging posts on eight topic categories from Sina Weibo, the most popular microblogging platform in China, are used for empirical analysis. A novel indicator named transfer tendency of a feature value is proposed to identify the important factors for attention transfer.FindingsThe accuracy of the prediction model based on Light GBM reaches 91%. It is found that user features are the most important for the attention transfer of microblogging users among all the features. The conditions of attention transfer in all aspects are also revealed.Originality/valueThe findings can help governments and enterprises understand the competition mechanism among multiple topics and improve their ability to cope with public opinions in the complex environment.
DC operating points of nonlinear circuits and generalized Carleman linearization
Authors: Weber Harry , Mathis Wolfgang 
Published: March 2023

Purpose
The purpose of this paper is to present a procedure for approximating DC operating points of nonlinear circuits. The presented approach can also be applied in case of multiple DC operating points.

Design/methodology/approach
A generalized Carleman linearization is used, which transforms an algebraic nonlinear equation into an equivalent infinite-dimensional linear system. In general, no close-form solution can be given for the infinite-dimensional linear system. Hence, the infinite-dimensional linear system is approximated by a finite one over a predefined interval using a self-consistent technique. The presented procedure allows to approximate all possible DC operating points within a predefined interval. To isolate all DC operating points, the initial interval is gradually divided into subintervals.

Findings
It is shown that the presented approach is not restricted to the polynomial case and allows to approximate all DC operating points. The presented approach can be applied in case of multiple DC operating points and does not depend on the domain of attraction of the DC operating points.

Originality/value
A new procedure for the approximation of DC operating points of nonlinear circuits based on a generalized Carleman linearization is presented. This approach can be applied in case of multiple DC operating points and is independent of the domain of attraction. Further, this generalized approach is not restricted to the polynomial case and can be applied to a variety of circuits.
Bio-networking among librarians, parents, and children in a modern children’s library: a phenomenological study
Authors: Guirguis Bernadette M. , Alsheikh Negmeldin 
Published: March 2023

Purpose
This study aimed to understand how parents and librarians describe their lived experiences in a modern children’s library that aims to create a triad bond through the organization of multiliteracy events and activities.

Design/methodology/approach
The study used a phenomenological case study approach using two semistructured interviews, the first with parents (n = 5) and the second with library staff (n = 5), to record their lived experiences in creating and attending literacy events and activities.

Findings
The findings indicated multiplicities of transformative and heterotypic spaces that juxtapose different yet compatible and vicarious experiences for librarians, parents and their children. The virtual and interactive features of the library fuel children’s curiosity and creativity and afford them authentic materials through a creative blend of local heritage and technology-mediated multimodal literacies. Moreover, the librarians engage in constant program evaluation and upgrades. The library environment creates a vibrant bio-network for disseminating literacy through creativity and ingenuity and affords an affinity space for community socialization.

Research limitations/implications
This study has some limitations and delimitations. The data for this study were collected during the pandemic, which affected the sample size. Moreover, the children’s views were not considered, which could broaden our understanding of the phenomena. Furthermore, the study relied on interviews as the sole source of data; other sources, such as archival data and documents, could enrich the data and increase the study’s rigor. Finally, the study is confined to only one site.

Practical implications
The study found that a “living library” philosophy with an enthusiastic and attentive staff that caters to patrons’ interests draws parents and children to visit. Additionally, unexpected fun activities that occur when sufficient children are present keep them engaged and motivated to stay and learn more. The study suggests that librarians, architects, school leaders, policymakers and educators should consider how to conceptualize, design and experience a modern library space that prioritizes literacy activities and incorporates technology to inspire children’s innovations. The findings can be applied to both public and academic libraries.

Originality/value
The findings from this study could provide researchers, teachers, administrators, librarians and artificial intelligence with a viable orientation to envision new ways of reconceptualizing public and school libraries to create affinity spaces for the literate community, especially in a non-western context such as the United Arab Emirates.
The effects of IT chargeback on strategic alignment and performance: the contingent roles of business executives' IT competence and CIOs' business competence
Authors: Cheng Rocky Chung-Ngam , Men Xiaohua , Hsieh J.J. Po-An , Cheng Zhuo June , Cui Xiaocong , Wang Tiange , Hsu Sheng-Hsun 
Published: March 2023

PurposeIn the era of the digital economy, organizations are under much pressure to justify their information technology (IT) spending on digital transformation. Some organizations have thus implemented IT chargeback, an IT governance (ITG) mechanism, to clarify and allocate IT costs among various business units. While practitioners have stressed the importance of IT chargeback, there has been little theoretical effort that investigates its strategic effects and boundary conditions.Design/methodology/approachSynthesizing the ITG literature and the resource-based view (RBV), the authors develop a research model to examine if IT chargeback affects IT–business strategic alignment and, in turn, organizational performance and how human IT resources strengthen the impacts of IT chargeback. The authors designed a survey to collect data from 103 firms and tested the model using partial least squares (PLS).FindingsThe authors found that IT chargeback promoted strategic alignment and then organizational performance only for firms with business-competent chief information officers (CIOs), rather than IT-competent business executives.Originality/valueThis study enriches the ITG literature by exploring the strategic value of an IT cost governance mechanism (i.e. IT chargeback). This study further proposes and validates a measure of IT chargeback. Drawing on the RBV, this study quantitatively investigates the strategic impacts and boundary contingencies of IT chargeback. This study also advances the CIO literature by identifying the strategic leading role, instead of the traditional supporting role, of CIOs in modern organizations.
Flawed public diplomacy: when Croatia Instagram Riviera narrative destination branding ignores dark tourism amateurs
Authors: Seccardini Gabriela , Desmoulins Lucile 
Published: March 2023

PurposeThis article tackles Croatian public diplomacy, destination and nation branding vis-à-vis an emerging Instagram trend to publish dark tourism related pictures sometimes using the official hashtag CroatiaFullOfLife; hence, poking Croatia tourism development accounts, which promote the country as merely a Riviera destination, and deletes the memories of Yugoslavian and Second Independence wars. Such a monolithic, shortsighted and amnesic destination branding strategy neglects alternative public tourism and public diplomacy opportunities.Design/methodology/approachThe article may improve the understanding of the links between the concepts of Public Diplomacy, nation and destination branding through an exploratory study of dark tourism amateurs experiences in Croatia, documented by pictures published on Instagram, the key digital social media for destination branding. It also outlines the history of Croatian tourism and government's efforts in promoting the overwhelming image of a sunny sea destination since the launching of the “Croatia Full Of Life” destination branding campaign in 2015. The study compares what and how dark tourism amateurs and Croatian main social media influencers publish contents destined to foreign publics.FindingsCroatia's official PR strategies and Instagram accounts ignore the increasing interest of foreign tourists, local younger generations and artists in abandoned places and Yugoslavian and Homeland War heritage monuments. These “light dark chiaroscuro” places are nowhere to be seen on Croatia's official Instagram account. Croatian government fails to embrace some aspects of the nation identity and to take advantage of Instagram trends and niche dark tourism influencers to boost and enrich its public diplomacy and the memorialization process of the darkest aspects of its past.Originality/valueThis research suggests that international Instagram influencers as well as local photographers, artists and history amateurs promote many shades of light–dark chiaroscuro tourism approaches. Their posts tell new narratives about the past and its memorialization, far from the silence and denial promoted by Croatian official Instagram accounts. Mainstream IG Croatian lifestyle marketing influencers and institutional accounts consistently shows beaches, blue waters and bikinis strictly respecting a monolithic, shortsighted and amnesic destination branding strategy. This study shows that some destination and nation-branding strategies could hinder rather than enhance public diplomacy.

Authors: Mengistu Desalegn Girma , Ashene Daniel Alemayehu , Halabo Handebo Ayele 
Published: March 2023

Purpose
The purpose of this study is to investigate the challenges and potential improvement mechanisms for the development of technology and innovation in the Ethiopian construction industry.

Design/methodology/approach
In this study both quantitative and qualitative research approaches were adopted. While a structured questionnaire was used for the quantitative data collection, semi-structured interview was used for qualitative data collection. In analyzing the quantitative data, mean score was used to rank the variables and factor analysis was conducted to identify the underlying dimensions of the research constructs. The qualitative data was analyzed thematically focusing on specific objectives of the study; the challenges and improvement mechanisms of technology and innovation development.

Findings
The findings indicate that the major challenges are nature of the industry and lack of awareness, weak capacity of companies and the regulatory instruments, inadequate tender duration and poor monitoring and controlling practice. The suggested improvement mechanisms are effective coordination of the process and awareness creation, promoting technology and innovation in the procurement process and technology and innovation consideration in construction project registration.

Originality/value
Effectiveness of construction industry improvement programmes is affected by inappropriateness of the adopted implementation mechanisms. Understanding the operating environment; the enablers and potential barriers, is important for the success of any envisioned improvement programme. The improvement framework proposed by this study indicates the potential intervention areas and improvement mechanisms to effectively induce and enhance technology and innovation development in the construction industry. Major pillars of the improvement framework are improving regulatory framework, raising awareness and stakeholder engagement and continual monitoring and controlling of the practice.
The physician CEO advantage and hospital performance during the COVID-19 pandemic: capacity utilization and patient satisfaction
Authors: Belasen Alan , Belasen Ariel , Feng Zhilan 
Published: March 2023

PurposePrior studies have shown that physician-led hospitals have several advantages over non-physician-led hospitals. This study seeks to test whether these advantages also extend to periods of extreme disruptions such as the COVID-19 pandemic, which affect bed availability and hospital utilization.Design/methodology/approachThe authors utilize a bounded Tobit estimation to identify differences in patient satisfaction rates and in-hospital utilization rates of top-rated hospitals in the United States.FindingsAmong top-rated US hospitals, those that are physician-led achieve higher patient satisfaction ratings and are more likely to have higher utilization rates.Research limitations/implicationsWhile the COVID-19 pandemic generated greater demand for inpatient beds, physician-led hospitals improved their hospitals’ capacity utilization as compared with those led by non-physician leaders. A longitudinal study to show the change over the years and whether physician Chief Executive Officers (CEOs) are more likely to improve their hospitals’ ratings than non-physician CEOs is highly recommended.Practical implicationsRecruiting and retaining physicians to lead hospitals, especially during disruptions, improve hospital’s operating efficiency and enhance patient satisfaction.Originality/valueThe paper reviews prior research on physician leadership and adds further insights into the crisis leadership literature. The authors provide evidence based on quantitative data analysis that during the COVID-19 pandemic, physician-led top-rated US hospitals experienced an improvement in operating efficiency.
