Fenestrated aortic arch prostheses represent a robust therapeutic option for select pathologies. The Najuta is a semicustomized stent graft designed to achieve reliable sealing zones for the supra-aortic vessels through a variable number of fenestrations. A defining aspect of the procedure is the creation of a through-and-through wire (TATW), which is executed through a transaxillary approach via the fenestration of the brachiocephalic trunk. The omission of the catheter rendezvous technique for safe removal of the TATW, as described herein, may result in severe complications, including damage to the fabric or secondary dislocation of the stent graft, potentially leading to catastrophic outcomes such as aortic dissection or stroke. During implantation, the Najuta prosthesis is introduced using a 4-m soft Terumo wire configured in a transaxillary-transfemoral TATW arrangement. A loop is then formed around the aortic valve, facilitating the safe advancement of the prosthesis into the aortic arch. This loop configuration must be untied after implantation. If this is performed carelessly, excessive tension may be exerted on the medial edge of the brachiocephalic trunk fenestration, which may potentially lead to fabric damage or secondary dislocation of the entire prosthesis. To avoid this, catheters are inserted via both the transaxillary and transfemoral access points. These catheters meet at the loop area in a controlled “rendezvous” maneuver, enabling the safe removal of the TATW via the transaxillary access. The catheter rendezvous technique ensures the safe extraction of the loop TATW during the implantation of the Najuta prosthesis, thereby enhancing procedural safety and minimizing patient risk.

Background. The coronavirus disease (COVID-19) is an infectious disease caused by the SARS-CoV-2 virus. A disturbance in the number of white blood cells results from direct damage to cells, primarily lymphocytes, by the SARS-CoV-2 virus. Aim. The work aims to examine the impact of the SARS-CoV-2 virus on the laboratory parameter values ​​in bedridden patients during hospitalization. Results. To determine the impact of COVID-19 infection on laboratory parameter values ​​, the study included 80 respondents hospitalized at the UCC Tuzla Infectious Diseases Clinic from 1.1.2021. - 31.12.2021. year. Among the respondents, 58.75% were men and 41.25% were women. A review of laboratory findings shows that there is a statistically significant difference between erythrocyte values ​​and the time of measurement (P=0.028). At admission, 93.75% of subjects had high C-reactive protein (CRP) values, 87.50% of subjects on day 5 of measurement, and 67.50% of subjects had high values ​​at discharge from the hospital. There was a statistically significant increase in CRP values ​​compared to reference values ​​(P=0.000). There was a statistically significant increase in platelets in subjects measured on admission (11.25% of subjects), on the 5th day of hospital stay (28.75% of subjects), and at discharge (33.75% of subjects) (P=0.000). Conclusion. Given the results obtained, we can conclude about the impact of the SARS-CoV-2 virus on the disruption of laboratory parameter values, especially the decrease in the number of erythrocytes and the increase in ferritin and C-reactive protein.

Cultural and event tourism plays a key role in the global tourism industry, contributing significantly to national, regional, and cross-border development strategies. It attracts visitors interested in cultural heritage, artistic events, and local traditions, supporting the preservation and promotion of local identity. Assessing cultural tourist flows become essential to understand their economic and social impact, and this article proposes an integrated methodology, combining quantitative and qualitative approaches, including data collection on cultural events, participant estimation, economic analysis, satisfaction assessment, data visualization, reporting, and continuous monitoring. The proposed model ensures a comprehensive evaluation of cultural tourist flows and supports the sustainable development of cultural tourism. Its relevance is both theoretical and applied: it offers a conceptual and analytical framework for studying this complex phenomenon, but also, it provides useful insights for decision-makers and stakeholders involved in tourism development, helping to design effective policies and strategies for promoting and managing cultural tourism. The novelty of the research lies in the proposal of a detailed and integrated methodology tailored to the specific challenges of evaluating cultural tourism, aiming to improve data accuracy, strategic planning, and long-term sustainability.

<p>In a period of global social and economic change, the teaching profession in transition countries is undergoing a profound transformation. Teachers of natural sciences and mathematics are particularly affected, as their role becomes crucial in developing the competencies necessary to understand and implement the principles of sustainable development. This paper analyzes the challenges and perspectives of the teaching profession in the context of educational reforms, technological changes, and the demands of the green economy. Using a comparative approach, the research examines the state of teacher education in the fields of natural sciences and mathematics in transition countries, with a special focus on Bosnia and Herzegovina. The results show that it is necessary to redefine teachers&rsquo; professional development through innovative pedagogical models, the integration of digital and environmental competencies, and an interdisciplinary approach to teaching. Particular emphasis is placed on strengthening teacher autonomy, continuous professional learning, and institutional support to empower teachers as agents of change within educational systems. The paper concludes that the future of the teaching profession, especially in the fields of natural sciences and mathematics, plays a key role in building a knowledge-based society and supporting a sustainable transition toward a green and inclusive economy.</p>

<p>In the pursuit of sustainable industrial transformation, additive manufacturing has emerged as more than a technological revolution&mdash;it represents a new philosophy of production. This paper explores how 3D and 4D printing technologies can serve as key enablers of waste reduction and resource optimization across diverse sectors. By shifting from traditional subtractive methods to digitally controlled additive processes, 3D printing minimizes material loss and energy use through precision, customization, and local production. Going a step further, 4D printing introduces smart, stimuli-responsive materials capable of self-adaptation and regeneration, creating systems that not only reduce waste but actively extend product lifecycles. Through an interdisciplinary lens, the study examines material innovation, eco-design principles, and the integration of artificial intelligence and digital twins for real-time optimization of manufacturing processes. The findings highlight the transformative potential of additive and time-evolving manufacturing in supporting circular economy objectives, Industry 5.0 paradigms, and the broader goals of the European Green Deal. Ultimately, the paper argues that the convergence of digital intelligence and material adaptability offers a tangible pathway toward regenerative, zero-waste production ecosystems. Its originality lies in bridging technological foresight with applied sustainability practice, offering actionable insights for industries and policymakers seeking to redesign value chains through intelligent, resourcepositive manufacturing.</p>

The aim of the study was to examine the attitudes of healthcare professionals and the general population towards stuttering. The study included a sample of 50 respondents from the Srebrenik, with 50% of respondents in group of healthcare professionals (N=25) and 50% in group of general population (N=25). The Alabama Stuttering Awareness Test was used as the research instrument. Analysis of the collected data revealed a statistically significant difference in the responses to the four statements examined. The results indicate the need for greater awareness of the general population regarding the provision of support to children who stutter and the necessity of improving healthcare professionals’ knowledge about stuttering. Given that healthcare professionals within primary healthcare play a key role in the early recognition of children who stutter, it is important to ensure their education so that they can adequately advise parents or guardians and refer children for speech therapy assessment and treatment in a timely manner.

<p>Bosnia and Herzegovina is in the early stages of energy transition. There is an obvious increased pressure to modernize existing waste management and environmental protection systems. Actions and actions at the EU and regional levels mark the ever-present need to develop hydrogen technologies and a circular economy. Waste is becoming a resource. The capital of Bosnia and Herzegovina should be a leader in changes of this kind. Sarajevo should be a model to be followed by other cities in the region. This city and its surroundings produce a huge amount of waste, which, if considered a resource, can, through the application of certain technological and technical solutions, become a source of energy and other raw materials for some industries such as the construction or metal industries. Therefore, Sarajevo has a special challenge and is expected to respond correctly and quickly. The Sarajevo landfill, Smiljevići, is the cause of serious problems that are reflected in large quantities of waste, its separation, the capacity of landfill surfaces, and the emission of gases and leachates. These problems have been unsolved for decades and are still a major challenge. They are two-dimensional as a<br />technical problem, but also as an institutional problem.</p>

Background: Refractory atrioventricular nodal reentrant tachycardia (AVNRT) is a rare condition, but poses a clinical challenge after failed standard ablation. Very high-power, short-duration (vHPSD) radiofrequency (RF) ablation has not yet been explored in slow pathway ablation/modification. Case Summary: A 61-year-old woman with recurrent AVNRT despite two prior ablations and multiple antiarrhythmics underwent successful slow pathway ablation using a 90-watt, 4-s vHPSD protocol. CARTO-guided mapping localized the presumed slow pathway, followed by several 90 W applications. Transient second-degree AV block (Wenckebach type) occurred and resolved spontaneously. The patient remained arrhythmia-free at 6-month follow-up. Conclusions: This is the first reported clinical use of 90 W/4 s RF energy for AVNRT. The vHPSD approach may offer an effective alternative for patients with refractory AVNRT.

Attributive relative clauses introduced by adverbial relativizers are rarely used in Modern Standard Arabic, and are completely absent in its syntactic description. The intriguing aspect of this type of relative clause lies in the fact that their attributive function is opposed to the main purpose of the use of adverbial relativizers, namely the formation of adverbial clauses. The main task of this paper is the analysis of examples of attributive relative clauses introduced by the adverbial relativizers ḥayṯu, ḥīna, ʻindamā, kamā and munḏu found in works belonging to Modern Standard Arabic. The analysis is based on the analytical–descriptive method and the typological–functional approach, which allow examining of attributive relative clauses introduced by adverbial relativizers from different perspectives. Although the analysis will include exploring syntactic functions of head nouns in main and relative clauses, whereby the relative clause formation strategy using the relative word to encode the syntactic function of head noun in the relative clause is illustrated, this is not the only goal of the paper. The paper also aims to demonstrate that attributive relative clauses introduced by adverbial relativizers, although formally functioning as attributive modifiers, tend to convey diverse semantic content. Moreover, this type of Arabic relative clause is not only an embodiment of the law of linguistic economy but it also represents an exceptionally effective means of stylistic choice.
