Introduction and importance:
Extraction of mandibular third molars can lead to complications such as chronic sclerosing osteomyelitis (CSO), an inflammatory bone marrow disease that tends to progress. CSO involves the cortical plates and often the periosteal tissues and is caused by a variety of microorganisms, including Corynebacterium spp. The treatment of CO and CSO remains challenging, as there is no universal treatment protocol. This case report investigated whether jaw bone that has healed from chronic sclerosing osteomyelitis can be considered healthy bone when planning dental implants.

Case presentation:
A 21-year-old Caucasian woman developed chronic osteomyelitis (CO) and CSO after third molar surgery.

Clinical discussion:
A combination of alveolar ridge bone resection, extraction of teeth 47–32, and long-term specific antibiotic therapy against Corynebacterium spp. was administered. An attempt at preprosthetic alveolar ridge reconstruction with an anterior superior iliac crest bone graft resulted in graft failure and the patient refused further harvesting procedures. Implantation in the intraforaminal zone also resulted in the loss of two implants after loading. Finally, inferior alveolar nerve transposition resulted in the successful reimplantation of two implants, which were fully functional almost 11 years later.

Conclusion:
This case report presents the treatment history of this patient. With a longitudinal observation period of >20 years, the results of this case demonstrate the successful treatment of bone with CO, CSO, and Corynebacterium spp. infection. Following the removal of infected bone, radical debridement, and long-term antibiotic therapy, bone health was restored.

Published: February 2024

Background
The association between hyperuricemia and development of progressive chronic kidney disease has received increasing attention in recent years. Recent preclinical studies have shown that non–crystalline uric acid can induce renal-specific arteriolopathy, leading to renal injury and tubulointerstitial inflammation.

Methods
We conducted a open-label cross-sectional study of 25 patients with chronic kidney disease stage III (estimated glomerular filtration rate [eGFR], 7.0 mg/dL) levels of serum uric acid. To determine the correlation between hyperuricemia on urinary protein levels and renal disease progression, we retrospectively compared urine protein and eGFR data between the 2 groups.

Results
Eleven patients with normal uric acid levels and 14 with hyperuricemia were enrolled. Urinary levels of both kidney injury molecule-1 (KIM-1) and monocyte chemoattractant protein-1 (MCP-1) were significantly higher in patients with hyperuricemia. Among the normouricemic White and African American (AA) subgroups, there was no difference in KIM-1 or MCP-1 levels, whereas KIM-1 levels were significantly higher among hyperuricemic AA patients with hyperuricemia. Urinary protein was significantly higher between Whites and AA patients with serum uric acid level >7.0 mg/dL as well as patients with urinary KIM-1 levels >1000 pg/mg Cr. A trend toward a more rapid decline in eGFR was noted among hyperuricemic AAs; however, this trend was not statistically significant.

Conclusions
Patients with type 2 diabetic nephropathy and persistently elevated serum uric acid levels express higher levels of both KIM-1 and MCP-1 reflective of on-going renal injury and inflammation.

Published: February 2024

Background:
This study aims to determine the population-based incidence and characterize the features of nonarteritic anterior ischemic optic neuropathy (NAION) using the Rochester Epidemiology Project (REP).

Methods:
All patients diagnosed with an optic neuropathy from January 1, 1990, to December 31, 2016, were retrospectively reviewed to identify incident cases of NAION using the REP database, which is a record-linkage system of medical records for all patient–physician encounters among Olmsted County, Minnesota residents. The overall incidence of NAION was estimated using the age-specific and sex-specific population figures for Olmsted County census data for 1990 through 2016. Visual outcomes and risk factors were evaluated. The systemic risk factors were compared with age-matched controls.

Results:
One hundred four patients were diagnosed with NAION during the 26-year study period. The overall age and sex adjusted incidence was 3.89 per 100,000 individuals (95% confidence interval [CI]: 3.14–4.65). The incidence was 7.73 (CI: 6.24–9.22) in patients aged 40 years or older and 10.19 (CI: 8.15–12.23) in patients aged 50 years or older. Median age at diagnosis was 65 years (range, 40–90 years), and 59 (56.7%) were male. The median logMAR visual acuity at presentation was 0.35 (Snellen equivalent of 20/40) with 14 patients (13.5%) having vision of counting fingers or worse. Among the 91 patients with final visual acuity outcome data available, the median visual acuity was 0.40 (Snellen equivalent of 20/50) with 12 patients (13.2%) having vision of counting fingers or worse. Twenty-four patients (26.4%) were noted to have final acuity at least 3 Snellen lines worse than at presentation, whereas 17 patients (18.7%) were noted to improve by at least 3 lines. The median mean deviation on automated visual field testing was −10.2 dB at presentation and −11.1 dB at follow-up. Twenty-two patients (21.2%) suffered NAION in the fellow eye; the median interval between involvement of the first and second eyes was 1.39 years. Systemic diseases present in the NAION cohort included hypertension (79.8%), diabetes mellitus (39.4%), obstructive sleep apnea (23.1%), and hyperlipidemia (74.0%), which were all statistically higher than age-matched controls.

Conclusions:
NAION is a relatively common optic neuropathy in elderly patients with vascular risk factors. Our data indicate that the incidence of NAION has remained relatively stable in the population of Olmsted County over the past 4 decades.
The demand of cancer patients to anticipate the management of undernutrition: is a nutrition prehabilitation before treatment conceivable as supportive care to improve quality of life? Argument for the NEHOTEL® concept
Authors: Philippe Pouillart , Flore Dépeint , Isabelle Soula , Bruno Raynard 
Published: February 2024

AbstractPurposeOur translational research team in nutrition and cancer works to identify changes in eating and cooking behaviors since the diagnosis. Educational tools have been standardized as supportive care workshops in culinary practice and nutrition to enhance quality of life with regards to symptoms associated with treatment. Ongoing work with a cluster of expert patients led to the conclusion that such tools are essential but may be addressed too late, once symptoms are present and undernutrition is set. We thus investigated the concept of an early nutritional and multimodal prehabilitation program to improve quality of life.MethodsOver a period of one year, 10 patients, together with researchers and caregivers co-constructed the NEHOTEL educational program. The relevance of this program was then confronted to the practical, medical and ethical points of view.ResultsAn innovative multimodal supportive care 5-days course has been validated with our panel of expert patients. In this setting, new cancer patients will be invited to a non-medical hotel facility specifically designed for this project.ConclusionsIn the synopsis of the cancer care path as currently conceived in France, the early positioning of this intervention, which formalizes the need for unmet supportive care of patients in nutrition, raises questions about its medico-technical feasibility and the chances of visualizing a benefit on the quality of life. NEHOTEL® concept design is the outcome of this translational work, supported by an ongoing clinical feasibility study.

ABSTRACTWith current trends in proteomics, especially regarding clinical and low input (to single cell) samples, it is increasingly important to both maximize the throughput of the analysis and maintain as much sensitivity as possible. The new generation of mass spectrometers (MS) are taking a huge leap in sensitivity, allowing to analyze samples with shorter liquid chromatography (LC) methods while digging as deep in the proteome. However, the throughput can be doubled by implementing a dual column nano-LC-MS configuration. For this purpose, we used a dual-column setup with a two-outlet electrospray source, and compared it to a classic dual-column setup with a single-outlet source.
The regulatory network of the White Collar complex during early mushroom development inSchizophyllum commune
Authors: Vonk Peter Jan , van der Poel Marieke J. P. , Niemeijer Zoé E. , Ohm Robin A. 
Published: February 2024

AbstractBlue light is an important signal for fungal development and is detected by the White Collar complex, which consists of WC-1 and WC-2. Most of our knowledge on this complex is derived from the ascomyceteNeurospora crassa, where both WC-1 and WC-2 contain GATA zinc-finger transcription factor domains. In basidiomycetes, WC-1 is truncated and does not contain a transcription factor domain, but both WC-1 and WC-2 are still important for development . In the model mushroomSchizophyllum commune, we show that dimerization of WC-1 and WC-2 happens independent of light, but that induction by light is required for promoter binding by the White Collar complex. Furthermore, the White Collar complex is a promoter of transcription, but binding of the complex alone is not always sufficient to initiate transcription. For its function, the White Collar complex associates directly with the promoters of structural genes involved in mushroom development, like hydrophobins, but also promotes the expression of other transcription factors that play a role in mushroom development.
The impact of management practices on export margins of firms: evidence from a recent Egyptian industrial survey
Authors: Kamal Yasmine 
Published: February 2024

PurposeThe paper aims at studying the effect of management practices on the extensive and intensive export margins of Egyptian manufacturing firms.Design/methodology/approachThe study relies on the 2020/2021 Egyptian Industrial Firm Behavior Survey (EIFBS) which comprises 2,383 manufacturing firms representing small, medium, and large sized firms located in different regions of Egypt: Urban Governorates, Lower Egypt, and Upper Egypt. It constructs an overall management z score for each firm to estimate its effect on a firm’s probability of exporting and value of exports using Ordinary Least Squares (OLS) regressions.FindingsResults indicate that good management is associated with a higher probability of firm exporting as well as higher export revenues conditional on exporting, robust to controlling for the level of domestic sales. These effects do not differ by firm ownership or type of sector, but rather by firm size, with managerial competence raising the probability of exporting more for large-sized firms. Additionally, good management is associated with higher firm productivity, innovation and worker training propensities which gives evidence that it is both an efficiency and a quality enhancer. Moreover, monitoring and targeting practices have significant positive effects on both margins, while incentives are only significant for the extensive margin.Practical implicationsFirms that aim at enhancing their export prospects and revenues should devote resources to review and upgrade their management systems to boost their product quality and production efficiency. Policy-wise, the government should create a competitive market environment that is open to both domestic and foreign firms’ entry to stimulate the adoption of better management practices.Originality/valueThe paper is the first to explore the link between firm management practices and export outcomes for a MENA country (Egypt). It makes use of a recent survey, the 2020/2021 Egyptian Industrial Firm Behavior Survey (EIFBS). The findings shed light on the importance of different management components (monitoring, targeting and incentives) in driving a manufacturing firm’s export performance.
Numerical modelling of heating and melting of metal in a mini industrial direct current electrical arc furnace
Authors: Pavlovs Sergejs , Jakovičs Andris , Chudnovsky Alexander 
Published: February 2024

Purpose
The purpose of this paper is the study of the electro-vortex flow (EVF) as well as heating and melting processes for mini industrial direct current electric arc furnace (DC EAF).

Design/methodology/approach
A mini DC EAF was designed, manufactured and installed to study the industrial processes of heating and melting a small amount of melt, being 4.6 kg of steel in the case under study. Numerical modelling of metal melting was performed using the enthalpy and porosity approach at equal values and non-equal values of the solidus and liquidus temperatures of the metal. The EVF of the liquid phase of metal was computed using the large eddy simulation model of turbulence. Melt temperature measurements were made using an infrared camera and a probe with a thermocouple sensor. The melt speed was estimated by observing the movement of particles at the top surface of melt.

Findings
The thermal flux for metal heating and melting, which is supplied through an arc spot at the top surface of metal, is estimated using the thermal balance of the furnace at melting point. The melting time was estimated using numerical modelling of heating and melting of metal. The process started at room temperature and finished once whole volume of metal was molten. The evolution of the solid/melt phase boundary as well as evolution of EVF patterns of the melt was studied.

Originality/value
Numerical studies of heating and melting processes in metal were performed in the case of intensive liquid phase turbulent circulation due to the Lorentz force in the melt, which results from the interaction of electrical current with a self-magnetic field.
How a leader in the footsteps of Atatürk enlightened the lives of thousands of children
Authors: Ünsal Efe 
Published: February 2024

Learning outcomes
The key learning from this case study include the following: first, there are various leadership types that leaders can exhibit, such as servant leadership and transformational leadership, and an individual’s leadership style can be evaluated by analysing his/her traits and behaviours. Second, decision-making is much more critical for leaders than for anyone else, and there are different approaches, such as rational and intuitive decision-making, that leaders can apply when making a decision. Third, in male-dominated work environments such as the sports sector, female executives should carefully weigh the risks and opportunities of leadership positions while being promoted.

Case overview/synopsis
The UPS Sports and Culture Club was founded in 2003 by Haluk Ündeğer in Zeytinburnu district, one of the most dangerous neighbourhoods in Istanbul that had a bad reputation for being high on crime and drugs. The club’s main goal was to train children from disadvantaged groups to develop a career in sports. Shortly after the club’s founding, Semra Demirer, a physical education teacher who had devoted her life to children’s physical, cultural and personal development, crossed paths with the UPS Club. In 2004, Demirer started to work at the UPS Sports and Culture Club as the general coordinator. She played an important role in the growth and development of many children over the years and helped raise very talented athletes such as Simge Aköz. In 2020, on the heels of financial and administrative difficulties, the club was at the risk of being shut down. Hence, Demirer grappled with the decision of whether to share this information with the employees and players in the club. She deeply considered how she could overcome the conflict between transparency and confidentiality she was experiencing.

Organizational learning, quality and safety culture in patient care: comparing Colombia and the Kingdom of Saudi Arabia
Authors: Santa Ricardo , Morante Diego , Tegethoff Thomas , Berggrun Luis 
Published: February 2024

Purpose
The purpose of this study is to determine the interactions between factors such as organizational learning, feedback about errors, punitive response to errors and communication quality in hospitals in the Kingdom of Saudi Arabia and Colombia when adopting a culture of quality and safety (CQS) in patient care.

Design/methodology/approach
Based on a literature review, a self-administered questionnaire was developed and used to collect data from 417 Saudi respondents affiliated with hospitals and 483 Colombian respondents at the beginning of the pandemic. Structural equation modeling is used in this study to test the hypothesized relationships.

Findings
The results show a solid and significant predictive relationship between feedback about errors and the CQS in both countries (Colombia: b = 0.55, p < 0.001; KSA: b = 0.44, p < 0.001), but a very low and insignificant predictive relationship between no punitive response to errors and CQS (Colombia: b = –0.02, p > 0.05; KSA: b = 0.05, p > 0.05).

Practical implications
This study demonstrates the importance of organizational learning in fostering a CQS in the health-care sector in the Kingdom of Saudi Arabia and Colombia. Recent unprecedented policy actions motivated by the COVID-19 pandemic, such as social distancing, lockdowns and safety practices enforcement, have further highlighted this concern. Moreover, attention to the dimensions addressed in this study is required for accreditation purposes in organizations seeking to promote a CQS. Overall, this research highlights the vital role of safety and quality practices among health-care organizations, which has significant policy implications, especially in the current period of high uncertainty.

Originality/value
This paper contributes to the theory and practice in the health-care sector by extending the current knowledge of the impact of the quality of communications, non-punitive response to errors and feedback about errors in organizational learning and safety culture, and by presenting a novel, quantitative methodology seldom used for these topics.
Reinforcing infrastructure equity through leveraging Envision rating system within construction education
Authors: Rahat Rubaya , Calle Müller Claudia , ElZomor Mohamed 
Published: February 2024

Purpose
Construction education rarely addressed the importance of disseminating knowledge on infrastructure equity, thus impeding progress toward creating equitable and sustainable developments. This study aims to investigate the existing sustainability courses under the American Council for Construction Education (ACCE) accredited construction management (CM) programs to examine the integration of infrastructure equity topics and assess improvement in CM students’ knowledge and awareness to address this issue through an intervention.

Design/methodology/approach
To achieve these objectives, this research reviewed the sustainability course descriptions of the ACCE-accredited undergraduate and graduate CM curricula. Furthermore, the study implemented a workshop within a CM sustainability course that taught the students about the key concepts of infrastructure equity as well as how to address this issue by leveraging the Envision infrastructure rating system.

Findings
The course review results showed that most sustainability courses lack topics such as infrastructure equity and social sustainability. Moreover, the analysis of pre- and postworkshop surveys indicated that guided training could improve the students’ understanding as well as boost their confidence to address and mitigate infrastructure inequity issues.

Originality/value
The findings of the study are valuable for increasing awareness of infrastructure equity and facilitating the future construction workforce with the required expertise to develop equitable infrastructure systems.
Validating two shortened versions of the fitness switching cost scale
Authors: Kim Kyungyeol , Lee Senyung 
Published: February 2024

PurposeAlthough the fitness switching costs scale (FSCS) was shown to have sound psychometric properties, the length of the 54-item may impose burdens on survey participants and present methodological and analytic challenges for researchers and practitioners. Therefore, the present study shortened and validated two versions of the FSCS, namely the 33-item FSCS (FSCS-33) and the 11-item FSCS (FSCS-11).Design/methodology/approachIn Study 1 (n = 411), the most useful items from the FSCS for the FSCS-33 and FSCS-11 were identified using item response theory (IRT). Study 2 (n = 391) and Study 3 (n = 400) assessed the psychometric properties of the FSCS-33 and FSCS-11, respectively, using partial least squares structural equation modeling.FindingsThe FSCS-33 and FSCS-11 demonstrated strong reliability and validity in assessing switching costs in fitness centers.Originality/valueThe psychometrically sound short-form scales provide researchers and practitioners with convenient and accurate means of measuring switching costs in fitness centers.
