The paper analyzes the sound of drones, both as environmental noise and as a parameter for their detection. The reasons for the psychoacoustic character of the noise and the conditions for effective acoustic detection are examined. Comparative results of sound measurements are provided for three types of reconnaissance drones individually, while hovering at different altitudes.

In the face of pressing socio-economic and environmental challenges, such as climate change, resource depletion, and social inequality, entrepreneurs are increasingly compelled to embrace innovative strategies that harmonize profitability with social and environmental stewardship. Artificial Intelligence (AI) holds promise in facilitating such solutions but requires careful examination to ensure its effective and ethical deployment in pursuit of sustainability objectives. The primary goal of this study was to ascertain whether AI significantly influences the sustainable entrepreneurial process. This comprehensive research framework integrates concepts from entrepreneurship, stakeholder theory, and digital technology, offering a multifaceted perspective. We employed the multiple regression analysis to examine data gathered from 40 entrepreneurs operating within the Bosnia and Herzegovina settings. The study's outcomes revealed that AI positively and significantly impacts the sustainable entrepreneurial process and its five sub-dimensions: “idea generation, opportunity recognition, opportunity development, venture launch, and positive impact”. This study enriches the literature on AI and sustainable entrepreneurship by offering empirical support for the impact of AI on the sustainable entrepreneurial process while also introducing and validating measurement tools for the sustainable entrepreneurial process. Additionally, entrepreneurs can utilize the findings of this research to strategically incorporate AI into their business processes and product/service innovation, improve operational efficiency, reduce costs, mitigate risks, enhance decision-making, foster collaboration across stakeholders, and capitalize on opportunities effectively.

The aim of this paper is to present a case of infective endocarditis (IE) caused by Staphylococcus aureus (S. aureus), focusing on diagnostic and therapeutic approaches. The paper highlights the importance of 2D transesophageal echocardiography (TOE) and discusses the capabilities and advances of appliance of the 3D TOE in patient evaluation, better understanding of the diagnosis, and timely treatment. The use of this advance echocardiographic modality allows clear visualization of complex and destructive tissue lesions, such as the perforation observed and presented in this case.

The study was conducted on the Obedska Bara Ramsar site at two localities, Krstonošića okno and canal Vok, to provide insight into fish community status by analysing fish biomass, biodiversity, and changes after restoration measures. A total of 685 fish samples were examined across four periods, from 2011 to 2023. Biodiversity index, relative biomass, and non-native species were analysed to evaluate the restoration measures’ influence. All parameters showed a negative trend until the restoration works were implemented, after which they increased. This study also provides recommendations to improve the site considering the Mission Restore our Ocean and Waters by 2030.

Objective Despite lack of evidence supporting efficacy, prophylactic fresh frozen plasma and Octaplas transfusions may be administered to very preterm infants to reduce bleeding risk. International variation in plasma transfusion practices in neonatal intensive care units (NICUs) is poorly understood, therefore, we aimed to describe neonatal plasma transfusion practice in Europe. Design Prospective observational study. Setting 64 NICUs in 22 European countries, with a 6-week study period per centre between September 2022 and August 2023. Patients Preterm infants born below 32 weeks of gestational age. Interventions Admission to the NICU. Main outcome measures Plasma transfusion prevalence, cumulative incidence, indications, transfusion volumes and infusion rates and adverse effects. Results A total of 92 of 1143 infants included (8.0%) received plasma during the study period, collectively receiving 177 transfusions. Overall prevalence was 0.3 plasma transfusion days per 100 admission days, and rates varied substantially across Europe. By day 28 of life, 13.5% (95% CI 10.0% to 16.9%) of infants received at least one plasma transfusion, accounted for competing risks of death or discharge. Transfusions were given for a broad range of indications, including active bleeding (29.4%), abnormal coagulation screen results (23.7%) and volume replacement/hypotension (21.5%). Transfusion volumes and infusion rates varied significantly; the most common volume was 15 mL/kg (range: 5–30 mL/kg) and the most common duration was 2 hours (range: 30 min to 6 hours). Conclusions We found wide variation in plasma transfusion practices in Europe, highlighting the need for evidence to inform neonatologists in daily practice and guidelines, in particular for non-bleeding indications. Trial registration number ISRCTN17267090.

Tumour DNA methylation has been investigated as a potential marker for breast cancer survival, but findings often lack replication across studies. This study sought to replicate previously reported associations for individual CpG sites and multi-CpG signatures using an Australian sample of 425 women with breast cancer from the Melbourne Collaborative Cohort Study (MCCS). Candidate methylation sites (N = 22) and signatures (N = 3) potentially associated with breast cancer survival were identified from five prior studies that used The Cancer Genome Atlas (TCGA) methylation dataset, which shares key characteristics with the MCCS: comparable sample size, tissue type (formalin-fixed paraffin-embedded; FFPE), technology (Illumina HumanMethylation450 array), and participant characteristics (age, ancestry, and disease subtype and severity). Cox proportional hazard regression analyses were conducted to assess associations between these markers and both breast cancer-specific survival and overall survival, adjusting for relevant participant characteristics. Our findings revealed partial replication for both individual CpG sites (9 out of 22) and multi-CpG signatures (2 out of 3). These associations were maintained after adjustment for participant characteristics and were stronger for breast cancer-specific mortality than for overall mortality. In fully-adjusted models, strong associations were observed for a CpG in PRAC2 (per standard deviation [SD], HR = 1.67, 95%CI: 1.24–2.25) and a signature based on 28 CpGs developed using elastic net (per SD, HR = 1.48, 95%CI: 1.09–2.00). While further studies are needed to confirm and expand on these findings, our study suggests that DNA methylation markers hold promise for improving breast cancer prognostication.

This study introduces a translation perspective to analyze the policy harmonization process, highlighting imitation, brokering, and editing in shaping policy dynamics at EU and national levels. The translation perspective emphasizes that while policy development is ongoing, the protracted process signals a shift in EU‐wide coordination of skilled labor migration. We show how ongoing translation efforts have transformed the coordination of skilled labor migration across the EU, as labor migration policies have translated into each other, resulting in mutual transformation. The study provides insights into the complex processes of policy harmonization via the Blue Card, enhancing understanding of EU labor migration policy. The findings demonstrate the continuous nature of policy translation between multiple contexts. The article traces developments surrounding the EU Blue Card Directive, including a parallel scheme in Austria, offering insights into skilled migration policy dynamics beyond linear diffusion models.

Healthy plantar pressure distribution beneath the feet plays a crucial role in children’s development from the very beginning, with any deviations potentially leading to various pathologic conditions. This review aims to examine recent applications of pedobarographic analysis in pediatrics applications, providing a clearer picture of current research practices and the topics being addressed. The authors conducted a comprehensive search across several scientific databases, including PubMed, Web of Science, Scopus, and Google Scholar, ultimately selecting 17 studies after applying specific criteria for inclusion. The findings demonstrate that pedobarographic analysis can effectively differentiate between age and sex differences in plantar pressure and detect the influence of various risk factors in healthy children. It was found that a child’s foot health is closely linked to their physical activity level, with body fat percentage playing a significant role in pressure distribution. Furthermore, external factors like school bags and internal factors such as obesity were identified as major contributors to abnormal plantar pressure, and pedobarography proved successful in detecting these effects. The analysis also showed that pedobarography is an effective tool for assessing foot health, tracking changes, and monitoring longterm recovery or trends in children. However, the review also highlights a limitation in the scarcity of research, particularly in the areas of gait and plantar pressure in children. Only a few studies have focused on young healthy athletes, suggesting that future research could delve deeper into this population.

Microneedles (MNs) are emerging as versatile tools for both therapeutic drug delivery and diagnostic monitoring. Unlike hypodermic needles, MNs achieve these applications with minimal or no pain and customizable designs, making them suitable for personalized medicine. Understanding the key design parameters and the challenges during contact with biofluids is crucial to optimizing their use across applications. This review summarizes the current fabrication techniques and design considerations tailored to meet the distinct requirements for drug delivery and biosensing applications. We further underscore the current state of theranostic MNs that integrate drug delivery and biosensing and propose future directions for advancing MNs toward clinical use.

Background: COVID-19 is a respiratory disease caused by a novel coronavirus, with a high mortality, especially in patients with underlying diseases. Patients with COVID-19 pneumonia may express an immune response such as cytokine storm or macrophage activation syndrome, which can lead to organ failure and death.Some studies suggest that corticosteroid and tocilizumab can improve the respiratory status and clinical outcome of patients with COVID-19 pneumonia. Aim: The aim of the study was to determine the potential effect of the use of tocilizumab and corticosteroids in patients with concomitant cardiovascular diseases on the clinical course and outcome during COVID-19 infection. Methods: We performed an observational retrospective study of adult patients admitted to “Travnik” and “Jajce” Hospital, Bosnia and Herzegovina, between 01.03.2020 and 01.12.2022 with confirmed COVID-19 and underlying cardiovascular disease (CVD). Results: The majority of patients (110 or 60.4%) had previously reported cardiomyopathy, and other cardiovascular disease included earlier myocardial infarction, stroke, cardiac arrhythmias, cardiac surgery, compensated cardial disease, and acute myocardial infarction. Total of 159 (87.4%) patients received corticosteroids during treatment. Tocilizumab has been used in 16 patients; nine survived and seven died. Conclusion: Even some studies proved that it might improve clinical presentation and prevent lethal outcomes; in our study there were no significant results to confirm this thesis.             Peer Review History: Received 28 September 2024;   Reviewed 15 November; Accepted 21 December; Available online 15 January 2025 Academic Editor: Dr. DANIYAN Oluwatoyin Michael, Obafemi Awolowo University, ILE-IFE, Nigeria, toyinpharm@gmail.com Average Peer review marks at initial stage: 6.0/10 Average Peer review marks at publication stage: 7.5/10

This paper presents the results of an action research conducted in a kindergarten in Sarajevo Canton. The participants were four female kindergarten educators who collaborated with two university professors who took the role of research leaders and moderators of reflective meetings. The action research was conceived as a model of professional development for preschool teachers in the Reggio pedagogy field, aiming to develop the skill of documenting pedagogical observation and the competence of implementing reflective practice (RP below the text) based on the Reggio principles. Data were collected on two levels: the educators documented their educational practice (photos, transcripts, videos, etc.), which was the basic material for analysis at collaborative reflective meetings, and all of it was documented by the research leaders. The data were analyzed simultaneously during the research (to decide on further action) and finally at the end of the research. The results of the research indicate that the action research raised awareness of the elements of traditional educational practice and developed the skills of pedagogical documentation management and the skill of implementing RP. Considering the limited time period for the realization of the research (14 months), significant but not optimal results were achieved, and there is still room for further progress in terms of improving the skills of keeping records and the capacity of RP implementation. It is necessary to systematically provide support for the professional development of educators through the development of reflective learning communities in kindergartens instead of the one-off and lecture-based forms that are offered.

The occurrence of spinal deformities during periods of rapid growth in children has been increasingly recognized as a significant issue within the broader community. This study aimed to evaluate the spinal posture during one of the most critical phases of physiological development in a specific group of preschool children. The research involved 153 preschool aged 4 to 6 years (mean age ± standard deviation: 4.6 ± 1.1 years) residing in Sarajevo. Postural assessment was conducted using the method proposed by Napoleon Wolanski (1975), which evaluates segmental relationships through the following parameters: head posture assessment (HPA), shoulder posture assessment (SPA), scapular posture assessment (SBPA), chest posture assessment (CPA), scoliotic posture evaluation (SCP), abdominal posture assessment (APA), leg posture assessment (LPA), and foot posture assessment (FPA). Deviations were categorized based on severity, assigned negative points as follows: 0 points for no deviation, 1 point for mild deviation, and 2 points for significant deviation. The associations between the eight parameters were analyzed using Spearman’s correlation coefficient (rho). The highest degree of correlation was observed between the variables of abdominal posture assessment and head posture assessment (0.536). Poor abdominal posture, often linked to weakened core muscles or imbalances in the lumbar region, can result in compensatory shifts in the head and neck to preserve balance and visual orientation.

Cyclosporine A (CsA) is widely used as an immunosuppressant in organ transplantation to improve graft survival and prevent tissue rejection. The impact of CsA on cancer progression is highly complex, influenced by the intricate relationship between immunosuppression and malignancy. While individuals with compromised immune systems, notably organ transplant recipients, face an elevated risk of cancer invasion and progression due to immunosuppressive regimens, CsA’s role in either promoting or inhibiting cancer remains elusive. Divergent outcomes from in vitro and in vivo studies suggest suppression of cancer progression under CsA treatment and complicate the translation of findings to clinical scenarios. Despite promising in vitro and in vivo results, the clinical application of CsA in oncology necessitates careful consideration of its toxicity profile in in vivo models, starting at 50–200 mg/kg/d. The divergence between preclinical and clinical findings highlights the need for further research to elucidate the true nature of CsA’s impact on cancer, providing a foundation for more informed and targeted therapeutic approaches.
